For example, they might be fixed connection, detachable connection, or integrated connection; might be direct connection or indirect connection through an intermediate medium, and might be internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in the present application can be understood under specific circumstances.

[0052] As shown in FIGS. 1-6, a first embodiment of the present application provides a connector 1 for connecting a seat bowl 100 and a base 200 (hereinafter referred to as connector 1 for short), including: a first part 2 facing the seat bowl 100 and a second part 3 facing the base 200 in a connected state, where the first part 2 and the second part 3 are arranged roughly oppositely, for example, the first part 2 is located at an upper part of the connector and the second part 3 is located at a lower part of the connector.

[0053] As shown in FIG. 3 and FIG. 4, a sewage hole 4 penetrating through the first part 2 and the second part 3 of the connector 1 is formed in a middle part of the connector 1, so that sewage in the seat bowl 100 can be discharged downward through the hole. The base 200 is also internally provided with a sewage passage, and sewage can be connected to the outside through a sewage pipe (not shown). The base 200 in the present application can be made by a blow molding process, and mainly has a supporting function, supporting the seat bowl 100 and other components and supporting a user who uses the toilet.

[0054] As shown in FIG. 2 and FIG. 3, a side of the connector 1 where the sewage hole 4 facing the seat bowl 100 is provided with a first groove 41 capable of accommodating a first sealing ring 5, so as to achieve the sealing between the connector 1 and the seat bowl 100.

[0055] The connector 1 is provided with a plurality of first mounting holes 6 and second mounting holes 7 around the sewage hole 4, which respectively penetrate through the first part 2 and the second part 3 of the connector 1. The first mounting holes 6 are configured to mount the connector 1 onto the seat bowl 100; for example, bolts can be inserted from the second part side to the first part side to fix the connector 1 to the seat bowl 100, and the first sealing ring 5 therebetween is also pressed. The second mounting holes 7 are configured to mount the connector 1 onto the base 200; for example, nuts may be pre-embedded at the first part side, and after the seat bowl 100 and the connector 1 are mounted, bolts may be inserted upward from the lower part of the base 200 to cooperate with the pre-embedded nuts to fix the base 200 with the connector 1.

[0056] As shown in FIGS. 2-4, the seat bowl 100 is made of ceramic material, and a recessed embedding groove 101 is formed in a bottom of the seat bowl. The whole connector 1 may be made of plastic material, which is manufactured by one-step molding and has certain rigidity and strength. The first part 2 of the connector is provided with a protruding embedding part 8 which is matched with the embedding groove 101; and by inserting the embedding part 8 into the embedding groove 101, the seat bowl 100 and the connector 1 can be matched and aligned.

[0057] Further, in order to solve the problem that opening precision of the ceramic seat bowl 100 is low and it is difficult to match, the embedding part 8 is surrounded by a plurality of fins which are distributed at intervals and able to be squeezed to deform, for example, elastic plastic sheets are adopted. These fins 9 may be configured to be evenly spaced along an outer wall of the embedding part 8; and an extending direction of each fin 9 is parallel to a connecting direction X between the seat bowl 100 and the connector 1, and extends vertically in FIG. 3, for example. A bottom of each fin 9 is fixed to the first part 2. A chamfer is formed at one end of each fin 9 toward/near the seat bowl 100, so as to guide the embedding part 8 and the fins 9 to be inserted into the embedding groove 101. When the seat bowl 100 is connected with the connector 1, the embedding part 8 and its fins 9 are in interference fit in the embedding groove 101 at the bottom of the seat bowl 100; in this process, at least part of the fins 9 will be squeezed, deformed, and possibly partially damaged, so as to completely fill in the embedding groove 101; because there may be machining accuracy errors in ceramic openings, the fins 9 will compensate for the operation errors to fix the ceramic seat bowl and bear a force in a horizontal direction, thus preventing the seat bowl from moving in the horizontal direction, and achieving high stability.

[0058] As shown in FIGS. 2-4, the connector 1 is provided with a water inlet pipe hole 10 through which a water inlet pipe 11 passes to introduce water from the outside. In a specific embodiment, a bracket 12 extending along the connecting direction X toward the seat bowl 100 is disposed at the first part 2 of the connector, adjacent to an edge of the connector; and the water inlet pipe hole 10 penetrates through the bracket 12. As shown in FIG. 2 and FIG. 4, a mounting groove 13 is also formed in the bracket 12, and the water inlet pipe 11 is provided with a sheet-type structure 14. By inserting the sheet-type structure 14 into the mounting groove 13, the water inlet pipe 11 is fixed to the bracket 12. Further, the mounting groove 13 includes a first groove 131 close to a side of the seat bowl, protruding limiting parts 132 located on two sides of the bracket 12, and an inserting part 133 close to a side of the base; the sheet-type structure 14 can be inserted into the mounting groove 13 from lower to upper from the inserting part 133, so that the top and the two sides of the sheet-type structure 14 are limited by the first groove 131 and the limiting part 132 respectively, and the inserting part 133 at the bottom is limited by the base after being combined with the base 200, thus fixing the water inlet pipe 11.

[0059] As shown in FIG. 3, a root part of the bracket 12 adjacent to the first part 2 of the connector can also be provided with a plurality of fins, which are respectively connected with the bracket 12 and the first part 2 of the connector, so that on the one hand, the stability of the bracket 12 can be enhanced, and on the other hand, the fins can be abutted against an opening at a tail of the seat bowl, thus exerting a function of interference fit similar to the fins of the embedding part.

[0060] The connector 1 is also provided with an up water pipe hole 15 and a down water pipe hole 16 which are adjacent to each other and penetrate through the first part 2 and the second part 3 of the connector respectively, so as to penetrate through an up water pipe and a down water pipe respectively (not shown). As shown in FIG. 3 and FIG. 4, the up water pipe hole 15 and the down water pipe hole 16 can both be located in a space surrounded by the embedding part 8, so that the embedding part 8 is oval, in which a hollow structure is formed. A partition part 17 is formed between the up water pipe hole 15 and the down water pipe hole 16, and the partition part 17 can support the corresponding up water pipe and down water pipe.

[0061] The seat bowl 100 has a hollow structure in which water can be stored. As shown in FIG. 5, the base 200 has a pedal-controlled water valve 202, and the water valve 202 is opened or closed by stepping with a foot outside. The water valve 202 is respectively connected with a water feed pipe and a water discharge pipe, wherein the water feed pipe is connected with the hollow structure of the seat bowl 100, and the water discharge pipe is connected with a water nozzle of the seat bowl; these technical solutions are known in the prior art, such as disclosed in CN103147499A. In the present embodiment, water from the outside can enter the hollow structure of the seat bowl 100 upward for storage after entering from the water inlet pipe 11; when the water valve 202 is opened, since the down water pipe (equivalent to the water feed pipe) is connected with the hollow structure of the seat bowl 100, the stored water can be guided to the water valve 202 of the base 200, and the opened water valve 202 guides the water to the up water pipe (equivalent to the water discharge pipe), and then the seat bowl is washed through the water nozzle of the seat bowl 100. The up and down here refer to the description of the flow direction of water with reference to FIG. 1 and FIG. 2.

[0062] As shown in FIG. 4, a pillar 18 is formed on the second part 3 of the connector extending along the connecting direction X toward the base 200. The pillar 18 can extend with the partition part 17 as the root so that the pillar 18 is located between the up water pipe hole 15 and the down water pipe hole 16. Reinforcing ribs extending to the second part 3 may be formed on two sides of the pillar 18 to increase its strength. The pillar 18 is configured to press the water valve 202 in the base 200, as shown in FIG. 5. Since the water valve will be stressed during the start-up, the water valve 202 can be fixed and the stress can be transmitted through the pillar 18.

[0063] As shown in FIG. 4 and FIG. 5, the second part 3 of the connector is provided with a buckle body 19 which can be clamped into a buckling groove 201 of the base 200. The buckle body 19 has an extension part 191 which can be squeezed and deformed, which is made of plastic, for example, and which has elasticity. A second protruding part 192 is provided at a free end of the extension part 191, so as to be clamped into the buckling groove 201; and one side of the second protruding part 192 toward the base 200 is an inclined surface 193 to guide the clamping. In addition, reinforcing ribs 194 may be provided between the extension part 191 and the second part 3 to enhance the strength of the buckle body 19. Through the connection between the buckle body 19 and the buckling groove 201, the gravity caused by a downward sitting pressure of the user in an opposite direction during use can be resisted.

[0064] As shown in FIG. 2 and FIG. 4, the sewage hole 4 extends along the connecting direction X toward the base 200, and an annular step shape 42 is formed at its free end, which can accommodate a second sealing ring 20 with an L-shaped cross section and adapted (matched) to an outer wall of the step shape 42, so as to achieve the sealing between the connector 1 and the base 200.

[0065] Further, in order to better fix the second sealing ring 20 and prevent it from falling off, as shown in FIG. 4 and FIG. 6, a plurality of first protruding parts 43 are arranged at an outer wall of the sewage hole 4 in a circumferential direction. A locking ring 21 for locking the sealing ring 20 has a plurality of openings 211 at a side close to the second part 3 of the connector 1; and a part of each opening 211 is blocked, thereby forming an enter-opening 212 and a limit-opening 213 which are interconnected with each other; an inner diameter of the locking ring 21 at a side far from the second part 3 of the connector 1 is smaller than an outer diameter of the second sealing ring 20. The first protruding part 43 is configured to be able to enter the enter-opening 212 of the locking ring 21, and then enter the limit-opening 213 of the locking ring 21 by rotation, so that the second sealing ring 20 is locked between the first protruding part 43 and the locking ring 21 and is not easy to fall off.

[0066] In the present embodiment, the sealing between the connector 1 and the base 200 mainly depends on the second sealing ring 20, and the stable connection therebetween mainly depends on the buckle body 19.

[0067] As shown in FIG. 3 and FIG. 4, the first part 2 and the second part 3 of the connector may also be formed with a plurality of recessed parts 22, and mesh-like reinforcing ribs 23 are arranged in at least a part of these recessed parts, so that the supporting strength of the connector 1 can be increased while the weight of the connector is reduced.

[0068] The second embodiment of the present application provides a portable toilet, as shown in FIG. 1 and FIG. 2, which includes the connector 1 for connecting the seat bowl and the base as described in the first embodiment.

[0069] As shown in FIGS. 7-11, a third embodiment of the present application provides another connector 1 for connecting a seat bowl 100 and a base 200. The connector includes: a first part 2 facing the seat bowl 100 and a second part 3 facing the base 200 in a connected state, where the first part 2 and the second part 3 are arranged roughly oppositely.

[0070] As shown in FIG. 9 and FIG. 10, a sewage hole 4 penetrating through the first part 2 and the second part 3 of the connector 1 is formed in a middle part of the connector 1, so that sewage in the seat bowl 100 can be discharged downward through the hole. The base 200 mainly has a supporting function, in which a movable sewage tank (not shown) that can be drawn out from one side can be provided to contain sewage.

[0071] As shown in FIG. 8 and FIG. 9, the connector 1 at a side where the sewage hole 4 facing the seat bowl 100 is provided with a first groove 41 capable of accommodating a first sealing ring 5, so as to achieve the sealing between the connector 1 and the seat bowl 100.

[0072] The connector 1 is provided with a plurality of first mounting holes 6 around the sewage hole 4, which respectively penetrate through the first part 2 and the second part 3 of the connector 1. The first mounting holes 6 are configured to mount the connector 1 onto the seat bowl 100; for example, bolts can be inserted upward from the lower part to fix the connector 1 to the seat bowl 100, and the first sealing ring 5 therebetween is also pressed.

[0073] The seat bowl 100 is made of ceramic material, and a recessed embedding groove 101 is formed in a bottom of the seat bowl. The connector 1 can be made of plastic material. The first part 2 of the connector is provided with a protruding embedding part 8 which is matched with the embedding groove 101; and by inserting the embedding part 8 into the embedding groove 101, the seat bowl 100 and the connector 1 can be matched and aligned.

[0074] Further, in order to solve the problem that opening precision of the ceramic seat bowl 100 is low and it is difficult to match, the embedding part 8 is surrounded by a plurality of fins 9 which are distributed at intervals and able to be squeezed to deform, for example, elastic plastic sheets are adopted. These fins 9 may be configured to be evenly spaced along an outer wall of the embedding part 8; and an extending direction of each fin 9 is parallel to the connecting direction X of the seat bowl 100 and the connector 1. A bottom of each fin 9 is fixed to the first part 2. A chamfer is formed at one end of each fin 9 toward/near the seat bowl 100, so as to guide the embedding part 8 and the fin 9 to be inserted into the embedding groove 101. When the seat bowl 100 is connected with the connector 1, the embedding part 8 and its fins 9 are in interference fit in the embedding groove 101 at the bottom of the seat bowl 100; in this process, at least part of the fins 9 will be squeezed, deformed, and possibly partially damaged, so as to be completely fill in the embedding groove 101; with the effect the same as that of the first embodiment.

[0075] The seat bowl 100 is provided with a water nozzle; the base 200 can store sewage; this technical solution is known in the prior art, such as disclosed in CN103147499A. In the present embodiment, water from the outside is directly connected to the water nozzle of the seat bowl 100 to wash the seat bowl 100, and then flows into the sewage tank in the base 200 through the sewage hole 4, so that no up water pipe nor down water pipe are provided as that in the first embodiment.

[0076] As shown in FIG. 10, the second part 3 of the connector is provided with a plurality of buckle bodies 19 around the sewage hole 4, which are arranged evenly and at intervals; and each of the buckle bodies 19 is located on a circumference of a same circle and is able to be clamped into an annular buckling groove (not shown) of the base 200, so as to be in a rotatable state. Each buckle body 19 has an extension part 191 which can be squeezed and deformed, which is made of plastic, for example, and which has elasticity. A second protruding part 192 is provided at a free end of the extension part 191, so as to be clamped into the buckling groove; and one side of the second protruding part 192 toward the base 200 is an inclined surface 193 to guide the clamping. Through the connection between the buckle bodies 19 and the buckling groove, a rotatable rail structure is formed, so that the connector 1 can rotate after being combined upwards with the ceramic seat bowl 100; in addition, the gravity caused by a downward sitting pressure of the user in an opposite direction during use can be resisted.

[0077] As shown in FIG. 10, the sewage hole 4 extends along the connecting direction X toward the base 200, and an annular step shape 42 is formed at its free end, which can accommodate a second sealing ring 20 with an L-shaped cross section and adapted (matched) to an outer wall of the step shape 42, so as to achieve the sealing between the connector 1 and the base 200.

[0078] In order to better fix the second sealing ring 20 and prevent it from falling off, as shown in FIG. 10 and FIG. 11, an outer wall of the sewage hole 4 may be provided with external threads; a locking ring 21 for locking the sealing ring 20 is provided with internal threads at a side close to the connector 1, and an inner diameter of the locking ring 21 at a side far from the connector 1 is slightly smaller than an outer diameter of the second sealing ring 20; and the rotation matching between the external threads of the sewage hole 4 and the internal threads of the locking ring 21 enables the second sealing ring 20 to be locked between the sewage hole 4 and the locking ring 21, and is not easy to fall off.

[0079] In the present embodiment, the sealing between the connector 1 and the base 200 mainly depends on the second sealing ring 20, and the stable connection therebetween mainly depends on the buckle bodies 19.

[0080] The first part 2 and the second part 3 of the connector may be formed with a plurality of recessed parts 22 to reduce the weight of the connector 1.

[0081] It can be seen that compared with the first embodiment, the third embodiment omits the up water pipe hole 15 and the down water pipe hole 16; it is not necessary to have the up water pipe hole and the down water pipe hole because the water is directly fed; and structures such as the second mounting holes 7 are also omitted. In addition, in the third embodiment, the connector 1 can rotate relative to the base 200, which improves the flexibility of the use scenario. It can be understood that some technical solutions of the two embodiments can be mutually referenced based on actual situations, such as the arrangement of the locking ring, the arrangement of the mesh-like reinforcing ribs, etc.

[0082] A fourth embodiment of the present application provides a portable toilet, as shown in FIG. 7, FIG. 8, FIG. 12 and FIG. 13, which includes the connector 1 for connecting the seat bowl and the base as described in the previous third embodiment.

[0083] Further, a clean water tank 300 for storing clean water is provided on the base 200, which is connected with the seat bowl 100 and able to directly provide clean water for the seat bowl 100.

[0084] An upper surface of the base 200 has one or more recessed second grooves 203 (as shown in FIG. 7 and FIG. 13); the clean water tank 300 has a third protruding part or third protruding parts 301 extending toward the base 200; and the third protruding part 301 can be embedded into the second groove 203 of the base 200 to fix the clean water tank 300 onto the base 200.

[0085] In some embodiments, as shown in FIG. 12 and FIG. 13, the clean water tank 300 also has a recessed arc-shaped part 302; and the arc-shaped part 302 is adjacent to a tail of the seat bowl 100, which limits excessive rotation of the seat bowl 100. When in use, the seat bowl can rotate about 90 degrees to the left and right respectively, but not 360 degrees completely.

[0086] In addition, the clean water tank 300 may also be provided with components such as water adding port and water flush button, which are well known to those skilled in the art.

[0087] Finally, it should be noted that the various embodiments in the present description are described in a progressive way, and each embodiment focuses on the differences from other embodiments, so it is necessary to refer to the same and similar parts between the embodiments.

[0088] The embodiments are only described as preferred embodiments of the present application, and are not intended to limit the scope of the present application.
