DETAILED DESCRIPTION OF THE INVENTION

[0082] To facilitate understanding of the object, characteristics and effects of the present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided below.

[0083] Refer to FIG. 1 showing a fluid joint structure of the present disclosure. The fluid joint structure includes a first body 1 and a second body 2. The first body 1 and the second body 2 may be ring-shaped. The fluid joint structure of the present disclosure is applicable to engineering pipelines, heat dissipation pipelines of servers or heat dissipation pipelines of data centers.

[0084] The first body 1 includes a first cavity 11. The first cavity 11 is movably provided with a first joint element 12. A first elastic element 13 is provided between the first cavity 11 and the first joint element 12. The first joint element 12 is configured to stop a fluid in the first cavity 11.

[0085] The second body 2 includes a second cavity 21. The second cavity 21 is movably provided with a second joint element 22. A second elastic element 23 is provided between the second cavity 21 and the second joint element 22. The second joint element 22 is configured to stop a fluid in the second cavity 21. The first body 1 is joined with the second body 2, such that the first joint element 12 and the second joint element 22 push against each other to generate a flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21 (wherein the fluid is a liquid or a gas).

[0086] In a joint method of the fluid joint structure of the present disclosure, the first body 1 and the second body 2 may be correspondingly joined, such that the first joint element 12 and the second joint element 22 push against each other to further generate a flow path of the fluid in the first cavity 11 and the second cavity 21, for the fluid to flow in the first cavity 11 and the second cavity 21. For example, the fluid is enabled to flow in a direction from the second cavity 21 to the first cavity 11, or to flow in a direction from the first cavity 11 to the second cavity 21, so that a required fluid is enabled to flow stably in the first body 1 and the second body 2.

[0087] In one embodiment of the present disclosure, one end of the first elastic element 13 pushes against the first joint element 12 and the other end of the first elastic element 13 pushes against one side of the first body 1, such that the first joint element 12 normally leans against the other side of the first body 1 and corresponds to the second joint element 22, so as to stop the fluid flowing through the first cavity 11. One end of the second elastic element 23 pushes against the second joint element 22 and the other end of the second elastic element 23 pushes against one side of the second body 2, such that the second joint element 22 normally leans against the other side of the second body 2 and corresponds to the first joint element 12, so as to stop the fluid flowing through the second cavity 21. Moreover, in this embodiment, the elastic force of the first elastic element 13 is equal to (or similar to) the elastic force of the second elastic element 23, such that the first joint element 12 and the second joint element 22 push against each other to recede simultaneously so as to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21.

[0088] On the basis of the above embodiment, when the fluid enters a pipe 24 of the second body 2, the second elastic element 23 may coordinate with the second joint element 22 to stop the fluid entering the second cavity 21. Once the first joint element 12 and the second joint element 22 butt and push against each other, the first joint element 12 and the second joint element 23 are enabled to recede simultaneously to compress the first elastic element 13 by the first joint element 12 and compress the second elastic element 23 by the second joint element 22, such that the first joint element 12 and the second joint element 22 push against each other and then generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the pipe 24 of the second body 2 and flows through the second cavity 21 to the first cavity 11, and then is guided by a pipe 14 of the first body 1 to a required position or apparatus, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0089] In one embodiment of the present disclosure, a first stop ring 15 is provided between the first joint element 12 and the first body 1, a second stop ring 25 is provided between the second joint element 22 and the second body 2, and a third stop ring 16 is provided between the first body 1 and the second body 2. With the coordination of the first stop ring 15, the second stop ring 25 and the third stop ring 16, the fluid is prevented from leaking from the first body 1 and the second body 2, thus enabling the fluid to flow stably in the first body 1 and the second body 2.

[0090] In one embodiment of the present disclosure, the first joint element 12 is provided with an alignment portion 121, and the second joint element 22 is provided with a corresponding alignment portion 221. The alignment portion 121 and the corresponding alignment portion 221 are configured for mutual alignment, limiting, anti-rotation, guiding alignment or guiding limiting. The first body 1 is provided with a first joint portion 17, and the second body 2 is provided with a second joint portion 26. The first joint portion 17 is in communication with the first cavity 11, and the second joint portion 26 is in communication with the second cavity 21. As such, the first joint portion 17 of the first body 1 and the second joint portion 26 of the second body 2 are enabled to join with each other, so that once the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt and push against each other, the first joint element 12 and the second joint element 22 are enabled to recede simultaneously to compress the first elastic element 13 by the first joint element 12 and compress the second elastic element 23 by the second joint element 22, such that the first joint element 12 and the second joint element 22 push against each other and then generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the pipe 24 of the second body 2 and flows through the second cavity 21 to the first cavity 11, and then is guided by the pipe 14 of the first body 1 to a required position or apparatus, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0091] In one embodiment of the present disclosure, the first body 1 has a fastened portion 18, the second body 2 has a fastening portion 27, and the fastened portion 18 and the fastening portion 27 are fastened with each other. In this embodiment, the fastened portion 18 is a groove, and the fastening portion 27 is a fastener. As such, the first joint portion 17 of the first body land the second joint portion 26 of the second body 2 are enabled to be joined with each other, and be fastened with each other by the fastened portion 18 and the fastening portion 27, thereby securely coupling the first body 1 and the second body 2 to further enable the fluid to flow stably in the first body 1 and the second body 2.

[0092] In one embodiment of the present disclosure, the first joint element 12 has a first neck 122, and the second joint element 22 has a second neck 222. As such, the distance by which the first joint element 12 and the second joint element 22 push against each other can be increased to adjust a travel stroke of the movement of the first joint element 12 and the second joint element 22.

[0093] In one embodiment of the present disclosure, the first elastic element 13 and the second elastic element 23 are springs or elastic bodies, thereby meeting actual application requirements.

[0094] In one embodiment of the present disclosure, when the first joint element 12 and the second joint element 22 come into contact with each other and push against each other to generate an outflowing fluid, the fluid is located at the first body 1 and the second body 2 or an anti-leak range of the first cavity 11 and the second cavity 21, so as to prevent leakage of the fluid to thereby meet actual application requirements.

[0095] In one embodiment of the present disclosure, the first body 1 and the second body 2 are joined with each other, such that the first body 1 and the second body 2 or the first cavity 11 and the second cavity 21 are leak-proof, and the first joint element 12 and the second joint element 22 come into contact with each other and push against each other to generate the outflowing fluid, so as to prevent leakage of the fluid to thereby meet actual application requirements.

[0096] Referring to FIG. 2 to FIG. 4, in one embodiment of the present disclosure, different from the above embodiments, the first body 1 has a first assembly member 100 at which the fastened portion 18 may be disposed, and the second body 2 has a second assembly member 200 at which the fastening portion 27 may be disposed. The fastened portion 18 has a neck 181 and a head 182, wherein the head 182 is disposed at one end of the neck 181. The fastening portion 27 has an entry portion 271 and a fitting portion 272. The entry portion 271 is in communication with the fitting portion 272, and the head 182 is smaller than the entry portion 271 but greater than the fitting portion 272.

[0097] On the basis of the above embodiment, when the first body 1 and the second body 2 are assembled, the head 182 of the fastened portion 18 is inserted into the entry portion 271 of the fastening portion 27, the first body 1 is then rotated (rotating the second body 2) to move the neck 181 of the fastened portion 18 into the fitting portion 272, hence forming a limiting effect by the head 182 and the fitting portion 272 so as to securely couple the first body 1 and the second body 2. When the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt and push against each other, the first joint element 12 and the second joint element 22 are enabled to recede simultaneously to compress the first elastic element 13 by the first joint element 12 and compress the second elastic element 23 by the second joint element 22, such that the first joint element 12 and the second joint element 22 push against each other and then generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the pipe 24 of the second body 2 and flows through the second cavity 21 to the first cavity 11, and is then guided by the pipe 14 of the first body 1 to a required position or apparatus, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0098] In one embodiment of the present disclosure, the first joint element 12 may be provided with a fourth stop ring 120, and the second joint element 22 may be provided with a fifth stop ring 220. With the coordination of the fourth stop ring 120 and the fifth stop ring 220, the fluid is prevented from leaking from the first body 1 and the second body 2, thus enabling the fluid to flow stably in the first body 1 and the second body 2.

[0099] In one embodiment of the present disclosure, different from the above embodiments, the second assembly member 200 may be provided with a limiting portion 204, and further includes a body 205, a fastener 206 and an elastic body 207. The body 205 is disposed at the second assembly member 200, and the elastic body 207 pushes against between the body 205 and the fastener 206. Moreover, the first assembly member 100 is provided with a corresponding limiting portion 183. As such, when the fastened portion 18 is fitted and assembled with the fastening portion 27, the fastener 206 of the limiting portion 204 is fitted with the corresponding limiting portion 183, so that the first body 1 and the second body 2 are securely coupled.

[0100] In addition, the fastened portion 18 may also be disposed at the second body 2, and the fastening portion 27 may be disposed at the first body 1, so as to meet actual application requirements.

[0101] As shown in FIG. 5, in one embodiment of the present disclosure, different from the above embodiments, the first body 1 has a connecting portion 19, the second body 2 has a corresponding connecting portion 28, and the connecting portion 19 is joined with the corresponding connecting portion 28. The fastened portion 18 may be a combination of a slide sleeve 186, an elastic body 187 and a plurality of rollers 188. The fastening portion 27 may be a groove, the first body 1 has a first coupling portion 101, and the second body 2 has a second coupling portion 201.

[0102] On the basis of the above embodiment, when the first body 1 and the second body 2 are assembled, with the coordination of the slide sleeve 186 and the elastic body 187 of the fastened portion 18, the rollers 188 are fitted into the fastening portion 27 to form a limiting effect, so that the first body 1 and the second body 2 are securely coupled. Moreover, when the connecting portion 19 is joined with the corresponding connecting portion 28, the second coupling portion 201 and the first coupling portion 101 come into contact with each other, and the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt and push against each other, so that the first joint element 12 and the second joint element 22 recede simultaneously to compress the first elastic element 13 by the first joint element 12 and compress the second elastic element 23 by the second joint element 22, such that the first joint element 12 and the second joint element 22 push against each other and then generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the pipe 24 of the second body 2 and flows through the second cavity 21 to the first cavity 11, and is then guided by the pipe 14 of the first body 1 to a required position or apparatus, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0103] As shown in FIG. 6 and FIG. 7, in one embodiment of the present disclosure, different from the above embodiments, the first joint element 12 has a first joint portion 123 and at least a first flow path 124, the second joint element 22 has a second joint portion 223 and at least one second flow path 224, and the first joint portion 123 and the second joint portion 223 push against each other for the fluid to flow in the first flow path 124 and the second flow path 224. As such, the first joint portion 123 of the first joint element 12 and the second joint portion 223 of the second joint element 22 are enabled to butt and push against each other to mutually communicate the first flow path 124 and the second flow path 224, for the fluid to flow in the first flow path 124 and the second flow path 224, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0104] In one embodiment of the present disclosure, the first flow path 124 and the second flow path 224 are grooves, recesses, pipes, protrusions, holes or steps, so that the present disclosure can meet actual application requirements.

[0105] In one embodiment of the present disclosure, the first joint element 12 has a first block portion 125, the second joint element 22 has a second block portion 225, the first block portion 125 blocks the first body 1, and the second block portion 225 blocks the second body 2. As such, the first block portion 125 of the first joint element 12 can coordinate with the first stop ring 15 to prevent the fluid from leaking from the first body 1 and the second body 2, and the second block portion 225 of the second joint element 22 can coordinate with the second stop ring 25 to prevent the fluid from leaking from the first body 1, for the fluid to flow stably in the first body 1 and the second body 2.

Moreover, stop rings 102 and 202 are disposed at the first body 1 and the second body 2, respectively.

[0107] On the basis of the above embodiment, when the first body 1 and the second body 2 are assembled, the second coupling portion 201 and the first coupling portion 101 come into contact with each other by joining the connecting portion 19 with the corresponding connecting portion 28, so that the first body 1 and the second body 2 are coupled stably by using the stop rings 102 and 202 to prevent leakage of the fluid. Moreover, the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt and push against each other, so that the first joint element 12 and the second joint element 22 recede simultaneously to compress the first elastic element 13 by the first joint element 12 and compress the second elastic element 23 by the second joint element 22, such that the first joint element 12 and the second joint element 22 push against each other and then generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the pipe 24 of the second body 2 and flows through the second cavity 21 to the first cavity 11, and is then guided by the pipe 14 of the first body 1 to a required position or apparatus, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

Moreover, when the second coupling portion 201 comes into contact with the first coupling portion 101, the second joint element 22 pushes against the second body 2 and then the second joint element 22 pushes against the first joint element 12 to recede so as to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21.

[0109] Moreover, according to requirements, the elastic force of the second elastic element 23 is greater than the elastic force of the first elastic element 13 (or the length, thickness or width of the first elastic element 13 is smaller than, greater than or equal to that of the second elastic element 23), the second joint element 22 coordinates with the second elastic element 23 to push against the first joint element 12 and the first elastic element 13 to recede (or the first elastic element 13 cannot recede any further, or the structure of the first elastic element 13 cannot recede any further, or the first elastic element 13 is compressed to an extent of no remaining elastic space, or the first elastic element 13 is compressed to be in an overlapping state), and then the first joint element 12 pushes against the second joint element 22 to recede so as to generate the flow path of the fluid, thereby meeting requirements of different flow directions of the fluid.

Moreover, when the first body 1 and the second body 2 are separated, the first joint element 12 first closes the first cavity 11, the fluid residing between the first body 1 and the second body 2 flows into the second cavity 21 due to the elastic force, the pressure of the fluid, the pressure of the flow direction or the inertia, and then the second joint element 22 closes the second cavity 21, so as to enable the present disclosure to meet different application requirements.

[0125] In one embodiment of the present disclosure, the elastic force of the first elastic element 13 is greater than the elastic force of the second elastic element 23 (or the elastic force of the second elastic element 23 is greater than that of the first elastic element 13, or a travel stroke of the first elastic element 13 is smaller than, greater than, equal to or similar to that of the second elastic element 23), and the fluid flows from the first body 1 toward the second body 2. When the first body 1 and the second body 2 are separated, the first joint element 12 first closes the first cavity 11 to meet different application requirements, the fluid residing between the first body 1 and the second body 2 flows into the second cavity 21 due to the elastic force of the first elastic element 13, or the force of fluid flowing from the first cavity 11 to the second cavity 21, or the pressure or inertia of the fluid flowing from the first cavity 11 to the second cavity 21, and then the second joint element 22 closes the second cavity 21, so as to enable the present disclosure to meet different application requirements.

[0126] In one embodiment of the present disclosure, when the first body 1 and the second body 2 are separated, the first joint element 12 first closes the first cavity 11, the fluid residing between the first body 1 and the second body 2 flows into the second cavity 21 due to the elastic force, the pressure of the fluid, the pressure of the flow direction, the inertia, the attraction or the center gravity, and then the second joint element 22 closes the second cavity 21, so as to enable the present disclosure to meet different application requirements.

[0127] In one embodiment of the present disclosure, the fluid may also flow from the second body 2 toward the first body 1. When the first body 1 and the second body 2 are separated, the second joint element 22 first closes the second cavity 21, or the fluid residing between the second body 2 and the first body 1 flows into the first cavity 11 due to the elastic force, the pressure of the fluid, the pressure of the flow direction or the inertia, and then the first joint element 12 closes the first cavity 11, so as to enable the present disclosure to meet different application requirements.

[0128] Referring to FIG. 21 and FIG. 22, in one embodiment of the present disclosure, a difference from the above embodiment is that, in addition to the first body 1 and the second body 2, the fluid joint structure further includes a motion unit 3.

[0129] The first body 1 includes a first cavity 11. The first cavity 11 is movably provided with a first joint element 12. The first joint element 12 is configured to stop a fluid in the first cavity 11.

[0130] The second body 2 includes a second cavity 21. The second cavity 21 is movably provided with a second joint element 22. A second elastic element 23 is provided between the second cavity 21 and the second joint element 22. The second joint element 22 is configured to stop a fluid in the second cavity 21, and the first body 1 is joined with the second body 2.

[0131] The motion unit 3 is movably assembled at the first body 1 (or movably assembled at the second body 2). The motion unit 3 and the first joint element 12 push against the second joint element 22 to generate a flow path of a fluid, for the fluid to flow in the first cavity 11 and the second cavity 21.

[0132] In a joint method of the fluid joint structure according to an embodiment of the present disclosure, the first body 1 is joined with the second body 2, such that the motion unit 3 pushes against the first joint element 12 and the first joint element 12 pushes against the second joint element 22 to generate a flow path of a fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. For example, the fluid flows in a direction from the second cavity 21 toward the first cavity 11, or the fluid flows in a direction from the first cavity 11 toward the second cavity 21, further enabling a required fluid to flow stably in the first body 1 and the second body 2.

[0133] In one embodiment of the present disclosure, a first elastic element 13 is provided between the first cavity 11 and the first joint element 12, the motion unit 3 is located on one side of the first body 1, one end of the first elastic element 13 pushes against the first joint element 12 and the other end of the first elastic element 13 pushes against the other side of the first body 1, such that the first joint element 12 normally leans against the motion unit 3 and corresponds to the second joint element 22, so as to stop the fluid flowing through the first cavity 11. One end of the second elastic element 23 pushes against the second joint element 22 and the other end of the second elastic element 23 pushes against one side of the second body 2, such that the second joint element 22 normally leans against the other side of the second body 2 and corresponds to the first joint element 12, so as to stop the fluid flowing through the second cavity 21.

[0134] On the basis of the above embodiment, when the fluid enters a fluid conduit 30 of the motion unit 3, the first elastic element 13 may coordinate with the first joint element 12 to stop the fluid entering the first cavity 11. Once the first body 1 is joined with the second body 2, the fastened portion 18 and the fastening portion 27 are fastened with each other, and the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt with each other. Then, the motion unit 3 pushes against the first joint element 12 and compresses the first elastic element 13, and the first joint element 12 pushes against the second joint element 22 and compresses the second elastic element 23, such that the first joint element 12 and the second joint element 22 push against each other to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. Thus, the fluid enters the motion unit 3 and flows through the first cavity 11 to the second cavity 21, and is then guided by the second body 2 to a required position or apparatus to further enable the required fluid to flow stably in the first body 1 and the second body 2.

[0135] In one embodiment of the present disclosure, a third elastic element 31 is provided between the motion unit 3 and the first body 1, and the motion unit 3 has a stop portion 32. One end of the third elastic element 31 pushes against the first body 1, and the other end of the third elastic element 31 pushes against the stop portion 32. Thus, with the pushing of the third elastic element 31, the motion unit 3 is enabled to be normally located at a position at which the first joint element 12 is not pushed against. When a force is applied to push against the motion unit 3, the third elastic element 31 is compressed, and when the force is not applied on the motion unit 3, the third elastic element 31 pushes against the motion unit 3 to be reset since the elastic force is released, thereby facilitating the motion unit 3 to again perform the function of pushing.

[0136] In one embodiment of the present disclosure, the second joint element 22 has a motion space 29, and the second joint element 22 coordinates with the motion space 29 by an insertion portion 203 so as to be movably disposed in the second cavity 21. As such, with the coordination of the motion space 29 and the insertion portion 203, the second joint element 22 is enabled to move stably in the second cavity 21.

[0137] In one embodiment of the present disclosure, the motion unit 3 is provided with a block portion 33, the first body 1 is provided with a corresponding block portion 104, and the block portion 33 and the corresponding block portion 104 are mutually stopped, so as to prevent the motion unit 3 from moving out of the first body 1 and to maintain a stable movement of the motion unit 3.

[0138] In one embodiment of the present disclosure, the motion unit 3 has an operating portion 34, and the operating portion 34 controls the first joint element 12. As such, a force may be applied to the operating portion 34 to control the motion unit 3 to enable the motion unit 3 to push against the first joint element 12.

[0139] In one embodiment of the present disclosure, the first joint element 12 and the motion unit 3 may be a multi-piece structure (for example, a two-piece structure), or the first joint element 12 and the motion unit 3 are an integrally formed structure. When the first joint element 12 and the motion unit 3 are an integrally formed structure, the motion unit 3 may link the first joint element 12, such that the first joint element 12 pushes against the second joint element 22 to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21. For example, the fluid flows in a direction from the second cavity 21 toward the first cavity 11, or the fluid flows in a direction from the first cavity 11 toward the second cavity 21 to further enable the required fluid to flow stably in the first body 1 and the second body 2, so that the present disclosure can better meet actual application requirements.

[0140] Referring to FIG. 23, in one embodiment of the present disclosure, a difference from the above embodiment is that, the fastened portion 18 of the first body 1 may be a groove, and the fastening portion 27 of the second body 2 may be a combination including a slide sleeve 273, an elastic body 274 and a plurality of rollers 275.

[0141] On the basis of the above embodiments, when the first body 1 and the second body 2 are assembled, with the coordination of the slide sleeve 273 and the elastic body 274 of the fastening portion 27, the rollers 275 are fitted into the fastened portion 18 to form a limiting effect, thereby securely coupling the first body 1 and the second body 2 to further enable a required fluid to flow stably flow in the first body 1 and the second body 2.

[0142] In one embodiment of the present disclosure, the motion unit 3 may be provided with a sixth stop ring 301 and a seventh stop ring 302, so as to maintain airtightness between the motion unit 3 and the first body 1 to achieve the effect of preventing leakage of the fluid.

[0143] Referring to FIG. 24 and FIG. 25, in one embodiment of the present disclosure, a difference from the above embodiment is that, the motion unit 3 is provided with a body 35, which is located on an outer periphery of the first body 1. By abutting the body 35 against the first body 1, the motion unit 3 can be maintained to move stably.

[0144] In one embodiment of the present disclosure, the motion unit 3 is provided with a fastened portion 36. The fastened portion 36 is disposed at the body 35, and the fastening portion 27 of the second body 2 and the fastened portion 36 are fastened with each other. As such, the first joint portion 17 of the first body 1 and the second joint portion 26 of the second body 2 are enabled to join with each other, so that when the alignment portion 121 of the first joint element 12 and the corresponding alignment portion 221 of the second joint element 22 butt with each other, with the coordination of the slide sleeve 273 and the elastic body 274 of the fastening portion 27, the rollers 275 are fitted into the fastened portion 36 to form a limiting effect, thereby securely coupling the second body 2 and the body 35 of the motion unit 3. Then, the motion unit 3 pushes against the first joint element 12, and the first joint element 12 pushes against the second joint element 22 to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 22, further enabling the required fluid to flow stably in the first body 1 and the second body 2.

[0145] Referring to FIG. 26, in one embodiment of the present disclosure, different from the above embodiments, the elastic force of the first elastic element 13 is greater than that of the second elastic element 23. When the first body 1 and the second body 2 are correspondingly joined, the first joint element 12 coordinates with the first elastic element 13 to push against the second joint element 22, the second joint element 22 compresses the second elastic element 23, and the second elastic element 23 is pushed against till there is no longer any compression space (or there is a slight compression space), such that the first joint element 12 pushes against the second joint element 22 to recede so as to generate the flow path of the fluid, for the fluid to flow in the first cavity 11 and the second cavity 21, further enabling the required fluid to flow stably in the first body 1 and the second body 2.
