(18) The present disclosure provides a conductive contact structure 10, which is applied to a power supply assembly 100. The power supply assembly 100 includes a cover body 50, and a main body 30 inbuilt with a master control board 90. The cover body 50 and the main body 30 define an installation space 70 therebetween. The conductive contact structure 100 is configured for supplying power to an external load. In the embodiments of the present disclosure, taking the external load being an atomizer for example, the power supply assembly 100 and the atomizer form an electronic cigarette.

(19) Referring to FIG. 1 to FIG. 7, in the embodiments of the present disclosure, the conductive contact structure 10 includes a negative electrode assembly 11, a sealing element 14, an insulating assembly 13 and a positive electrode assembly 12 that are disposed in sequence in the installation space 70. The negative electrode assembly 11 is configured for passing through the cover body 50 to abut against the sealing element 14 and defines a through hole 1111 configured for installing an external load. The insulating assembly 13 has one end configured for covering the positive electrode assembly 12 on the main body 30 and has the other end abutting against the sealing element 14. The positive electrode assembly 12 is configured for partially passing through the insulating assembly 13 and the sealing element 14 in sequence to be accommodated in the through hole 1111. The master control board 90 is configured to be in electric connection with the positive electrode assembly 12 and the negative electrode assembly 11.

(20) According to the conductive contact structure 10 in the technical scheme of the present disclosure, the negative electrode assembly 11 passes through the cover body 50 to abut against the sealing element 14, so that the tobacco liquid can be prevented leaking from the outer circumference of the negative electrode assembly 11 and from the gap between the through hole 1111 and the insulating assembly 13; meanwhile, the positive electrode assembly 12 partially passes through the insulating assembly 13 and the sealing element 14 in sequence to be accommodated in the through hole 1111, that is, the sealing element 14 is sleeved on the positive electrode assembly 12, which further prevents the tobacco liquid leaking from the gap between the positive electrode assembly 12 and the insulating assembly 13. The sealing performance of the conductive contact structure 10 is effectively enhanced. The condition that the tobacco liquid leaks into the power supply assembly 100 from the conductive contact structure 10 is avoided.

(21) Specifically, as shown in FIG. 1, FIG. 4 and FIG. 5, in the embodiments of the present disclosure, one of the insulating assembly 13 and the sealing element 14 is provided with at least one locating block 1311 while the other one defines locating grooves 1421. One of the locating blocks 1311 is inserted into one of the locating grooves 1421 so as to fix the sealing element 14 to the insulating assembly 13. Here, in the present embodiment, the sealing element 14 is made of elastic silicone materials. The insulating assembly 13 is provided with two locating blocks 1311 spaced apart on one end facing the cover body 50. The two locating blocks 1311 are configured to be disposed opposite to each other and spaced apart from each other at two sides of the positive electrode assembly 12. The sealing element 14 defines two locating grooves 1421 correspondingly. The sealing element 14 is fixed to the insulating assembly 13 by way of buckling the two locating elements in the two locating grooves 1421. The connection is firm and the sealing element 14 is convenient to install. Meanwhile, the condition that the sealing element 14 produces a displacement to result in a gap in the usage process is effectively avoided. Moreover, the elastic silicone material has certain elasticity and can be in tight fit with the insulating assembly 13 and the negative electrode assembly 11, thereby further avoiding the generation of gap.

(22) It is understandable that, in the actual application, the number and the installation position of the locating block 1311 and the locating groove 1421 are not limited to the manner in the above embodiment that they are disposed opposite to each other and spaced apart from each other at two sides of the positive electrode assembly 12, and that users can select other numbers and installation positions according to specific sizes or shapes. The latter manner is also included in the scope of protection of the present disclosure.

(23) Specifically, as shown in FIG. 5, in the embodiments of the present disclosure, the sealing element 14 includes a big-diameter portion 141 and at least one small-diameter portion 142 located at the periphery of the big-diameter portion 141. The big-diameter portion 141 is configured for blocking the through hole 1111 and defines a relief hole 1411 allowing the positive electrode assembly 12 to pass through. The small-diameter portion 142 is opened/provided with the locating groove 1421/locating block 1311. Here, in the present embodiment, the big-diameter portion 141 is provided with two small-diameter portions 142 at two sides thereof, and the big-diameter portion 141 blocks the through hole 1111 so as to effectively prevent the tobacco liquid leaking from the through hole 1111. The two small-diameter portions 142 are integrated with the big-diameter portion 141. The two locating grooves 1421 are sleeved on the two locating blocks 1311 provided on the insulating assembly 13. Such arrangement avoids that a whole piece of big-diameter sealing element 14 is needed to seal the parts. The material cost is effectively saved, and the installation space 70 is reduced.

(24) Specifically, as shown in FIG. 2 and FIG. 3, the relief hole 1411 is defined directing facing a center position of the through hole 1111, and the relief hole 1411 has a diameter smaller than that of the through hole 1111. Here, in the present embodiment, the relief hole 1411 is defined directing facing the center position of the through hole 1111 and the relief hole 1411 has the diameter smaller than that of the through hole 1111. Such arrangement effectively ensures that the positive electrode assembly 12 is accommodated in the middle of the through hole 1111 and that the positive electrode assembly 12 keeps certain distance from the negative electrode assembly 11 all the time, and avoids the condition that the negative electrode assembly 11 and the positive electrode assembly 12 are in direct contact to cause a safety hazard of short circuit.

(25) Specifically, as shown in FIG. 1 to FIG. 4, in the embodiments of the present disclosure, the insulating assembly 13 includes a limiting plate 31 and an insulating plate 131 that fit a lateral edge structure of the positive electrode assembly 12. The limiting plate 31 is configured to be installed on the main body 30 and to enclose an accommodating groove 32. The insulating plate 131 has one end configured for covering the accommodating groove 32 and has the other end provided with at least one locating block 1311. The positive electrode assembly 12 has one end elastically installed in the accommodating groove 32 and abutting against the insulating plate 131 and has the other end passing through the insulating plate 131 and the relief hole 1411 to be accommodated in the through hole 1111. Here, in the present embodiment, the limiting plate 31 encloses the accommodating groove 32, the positive electrode assembly 12 has one end elastically installed in the accommodating groove 32, and the insulating plate 131 covers the accommodating groove 32 and thus covers the positive electrode assembly 12 on the main body 30, so that the outer circumference of the positive electrode assembly 12 is packaged. Such arrangement can avoid the condition that an external conducting component (not shown in the drawings) contacts the positive electrode assembly 12 by error to cause a short circuit, and avoid the condition that the positive electrode assembly 12 shakes in the usage process to contact the negative electrode assembly 11 to cause a short circuit. The yield and safety of the power supply assembly 100 are effectively improved.

(26) Specifically, as shown in FIG. 1 to FIG. 3 or in FIG. 7, in the embodiments of the present disclosure, the insulating assembly 13 includes an insulating ring 132. The insulating ring 132 is configured to be sleeved on the outer circumference of the positive electrode assembly 12 located inside the through hole 1111 and is configured to abut against an inner wall of the through hole 1111. Here, in the present embodiment, since the sealing element 14 is made of elastic silicone materials, the sealing element 14 has a soft texture. In order to avoid the condition that the positive electrode assembly 12 produces a displacement to directly contact the negative electrode assembly 11 to cause a short circuit in the long-time usage process, the insulating ring 132 is sleeved on partial outer circumference of the positive electrode assembly 12 located inside the through hole 1111, and an end portion of the negative electrode assembly 11 close to the positive electrode assembly 12 is expanded gradually or is provided with a limiting step to fit and abut against the insulating ring 132, so that the positive electrode assembly 12 and the negative electrode assembly 11 do not contact each other directly to cause a short circuit.

(27) Specifically, as shown in FIG. 1 to FIG. 3 or in FIG. 7, in the embodiments of the present disclosure, the negative electrode assembly 11 includes a connector 111 and a conducting ring 112. The connector 111 has one end embedded into the cover body 50 and the other end accommodated in the installation space 70. The through hole 1111 is defined in the connector 111. The conducting ring 112 is configured to be sleeved on the connector 111 and abut against the sealing element 14. The connector 111 is limited in the installation space 70. The conducting ring 112 is configured for electrically conducting the connector 111 to the master control board 90. Here, in the present embodiment, the connector 111 has one end embedded into the cover body 50 and the other end accommodated in the installation space 70, and the conducting ring 112 is sleeved on the connector 111 by interference fit and abuts against the sealing element 14. Such arrangement effectively prevents the tobacco liquid leaking from the gap between the conducting ring 112 and the insulating assembly 13. Meanwhile, the connector 111 is fixed to the cover body 50, the connection is firm and no bolt is needed. Furthermore, the external load has a contact electrode fixedly and electrically connected to the connector 111 via the through hole 1111, thus, the conductive contact area is big, the stability of the electrical conduction is effectively ensured, and the generation of burning sensation is avoided when a big current passes.

(28) Specifically, as shown in FIG. 7, in the embodiments of the present disclosure, the conducting ring 112 has an outer circumference extending out a wiring pin 1121, and the wiring pin 1121 defines a wiring hole. A lead wire is configured to passes through the wiring hole to be welded to the wiring pin 1121, thereby realizing electrical conduction. Such arrangement effectively facilitates the wiring and welding in a narrow space.

(29) Specifically, as shown in FIG. 1 to FIG. 3, in the embodiments of the present disclosure, the through hole 1111 has the inner wall provided with connection threads (not marked in the drawings), the connection threads being configured to be in connection with a contact electrode of a load. Here, in the present embodiment, the negative electrode assembly is connected to the contact electrode of the load through the connection threads. The assembly and disassembly are convenient. Meanwhile, the connection is more stable and the structure is not easy to shake.

(30) Specifically, as shown in FIG. 3 and FIG. 4, in the embodiments of the present disclosure, the positive electrode assembly 12 includes a conducting column 121 and a conducting elastic sheet 122. The conducting column 121 has one end passing through the insulating assembly 13 and the sealing element 14 to be accommodated in the through hole 1111 and has the other end fixedly connected to the conducting elastic sheet 122. The conducting elastic sheet 122 is configured to be fixedly installed on the master control board 90 and to be electrically conducted to the conducting column 121. Here, in the present embodiment, the conducting column 121 passes through the insulating plate 131 of the insulating assembly 13 and the sealing element 14 in sequence to be accommodated in the connection hole, so that the conducting column 121 keeps certain distance from the negative electrode assembly 11 all the time. When a load is installed on the power supply assembly, the load has an outer circumference negative contact electrode electrically connected to the connector 111 of the negative electrode assembly 11 and has a positive contact electrode abutting against the conducting column 121, so as to form an electric circuit. Meanwhile, the positive electrode assembly 12 is provided with the conducting elastic sheet 122, so that the positive electrode assembly 12 can be welded to the master control board 90 through the conducting elastic sheet 122 to realize electrical connection. Such arrangement avoids the connection through lead wires, further improves the product quality, and reduces the safety hazards caused by rosin joint. Meanwhile, wires are directly arranged on the master control board 90 and are electrically connected to the wiring pin 1121, so that the contact area is far greater than that of lead wire connection and the power supply assembly can bear a load with big current. Furthermore, the conducting elastic sheet 122 has certain elasticity. When a load is installed, the load presses against the conducting column 121, then, the conducting elastic sheet 122 applies certain elastic force to the conducting column 121 correspondingly, so that the conducting column 121 tightly abuts against the positive contact electrode of the load. The stability of current conduction is effectively enhanced.

(31) Specifically, as shown in FIG. 3 or FIG. 6, in the actual application, the conducting elastic sheet 122 in the technical scheme of the present embodiment is provided with a bended portion 1221, to further enhance the elastic force of the conducting elastic sheet 122.

(32) Specifically, as shown in FIG. 1 to FIG. 3, in the embodiments of the present disclosure, the positive electrode assembly 12 further includes an elastic element 123. The elastic element 123 has two ends abutting against the main body 30 and the conducting column 121 respectively. Here, the present embodiment arranges the elastic element 123 in the accommodating groove 32, thereby further enhancing the elastic force of the conducting column 121, so that the conducting column 121 can be in tight fit with the positive contact electrode of the load; meanwhile, the activity of the conducting column 121 can be increased, so that the conducting column 121 can dock various types of loads.

(33) Specifically, as shown in FIG. 2, FIG. 3 or FIG. 6, in the embodiments of the present disclosure, the accommodating groove 32 has an inner wall provided with an elastic element fixing column (not shown in the drawings) corresponding to the positive electrode assembly 12; and/or, the conducting column 121 defines an accommodating chamber 1211 configured for accommodating the elastic element 123. Here, in the present embodiment, the arrangement of the elastic element fixing column and the action of sleeving the elastic element 123 on the elastic element fixing column can effectively prevent the elastic element 123 shaking and displacing in the usage process. Likewise, the arrangement of the accommodating chamber 1211 defined on the conducting column 121 for accommodating the elastic element 123 also can effectively prevent the elastic element 123 shaking and displacing in the usage process. The structure is more compact and the installation space 70 is reduced.

(34) It is understandable that the elastic element 123 can employ a pressure spring or an elastic plastic in the actual application, and that the fixing manner of the elastic element 123 is not limited to the above manner of employing the elastic fixing column or defining the accommodating chamber 121. For example, the elastic element 123 also can employ a conical spring, and the big-diameter end of the conical spring is configured to abut against the limiting plate 31 to realize fixation. The manner in the example is also in the scope of protection of the present disclosure.
