[0027] Please refer to Figure 1. An embodiment of the present application provides an electronic atomization device. The electronic atomization device 30 includes an atomizer 20 and a battery assembly 10. The battery assembly 10 is electrically connected to the atomizer 20. The atomizer 20 serves as an electrical component of the battery assembly 10, and the battery assembly 10 is used to power the atomizer 20.

[0028] Referring to Figures 2 and 3, a battery assembly 10 provided in an embodiment of the present application includes a housing 100, a limiting assembly 11, an energy storage component 400 and a conductive column 500. The energy storage component 400 is disposed in the housing 100, and the conductive column 500 is at least partially located outside the housing 100 for connection with external electrical components. At least part of the limiting assembly 11 is disposed in the housing 100 to seal the housing 100, and the limiting assembly 11 is provided with a limiting hole 12. The energy storage component 400 includes a pole 410, and the pole 410 is passed through the limiting hole 12. The conductive column 500 is embedded in the limiting hole 12 and is at least partially located outside the housing 100. The conductive column 500 is hollow at one end facing the energy storage component 400 and is conductively plugged with the pole 410, and the other end of the conductive column 500 is used to contact and electrically connect the electrical components.

[0029] In the above-mentioned battery assembly 10, the conductive column 500 and the pole part 410 are conductively plugged in the limiting channel 12, so that the energy storage component 400 can be electrically connected with the external electrical component. In addition, the conductive column 500 is used as an intermediate connector to replace the pole ear to connect with the external electrical component, so that the energy storage component 400 and the electrical component do not need to use a fixed connection method such as solder wire connection. In other words, the conductive column 500 replaces the pole part 410 to connect with the electrical component. Compared with the pole part 410, the conductive column 500 can be conveniently set to be electrically connected to the electrical component in various flexible ways, such as being set to a detachable connection. Furthermore, the conductive column 500 and the limiting assembly 11 are connected and installed in an embedded manner, and the conductive connection between the conductive column 500 and the pole part 410 is plug-in. The embedded and plug-in connection methods are simple, which is convenient for realizing the automated assembly of the conductive column 500 and improving production efficiency.

[0030] Please continue to refer to Figures 2 and 3. In one embodiment, the limiting assembly 11 includes a sealing plug 200 and a top sleeve 300. The sealing plug 200 is at least partially disposed in the housing 100 to seal the housing 100. For example, the sealing plug 200 can be made of soft rubber materials such as silicone and rubber to facilitate sealing the housing 100. The sealing plug 200 can be made of butyl rubber.

[0031] Furthermore, an opening 110 is provided at one end of the housing 100, and the pole portion 410 extends through the opening 110 to the outside of the housing 100 and is conductively plugged with the conductive column 500, so as to transmit electrical energy to the outside through the conductive column 500. Of course, the pole portion 410 can also be arranged to be completely located in the housing 100, in which case the conductive column 500 can extend into the housing 100 through the opening 110 and be conductively plugged with the pole portion 410. In short, the pole portion 410 at least partially located in the housing 100 is conductively connected to the conductive column 500 at least partially located outside the housing 100 through the opening 110. The sealing plug 200 is provided at one end where the opening 110 is located, and the sealing plug 200 is used to block the opening 110.

[0032] In one embodiment, the top sleeve 300 is at least partially located outside the housing 100, and the limiting channel 12 extends from the sealing plug 200 to the top sleeve 300, so that the pole portion 410 is conductively plugged with the conductive column 500 along the limiting channel 12. The conductive column 500 is plugged with the top sleeve 300 by interference, and the top sleeve 300 and the housing 100 are relatively fixed. After the top sleeve 300 and the housing 100 are relatively fixed, the conductive column 500 that is plugged with interference in the top sleeve 300 also has a relatively stable position.

[0033] In one embodiment, the battery assembly 10 further includes a battery rack 13, and the top sleeve 300 and the shell 100 can be respectively installed on the battery rack 13 to achieve relative fixation. Of course, in other embodiments, the top sleeve 300 and the shell 100 are not limited to being relatively fixed only by the battery rack 13, and the two can also be fixed in a more direct manner. For example, the top sleeve 300 is set to be connected to the end surface of the shell 100 by gluing to achieve fixation. Alternatively, the top sleeve 300 can also be set to be sleeved on the end of the shell 100 to achieve fixation. For another example, the top sleeve 300 can also be set to penetrate the opening 110 to achieve fixation. For another example, the top sleeve 300 and the sealing plug 200 can also be set to be integrated. At this time, the part of the top sleeve 300 located outside the shell 100 in the limit assembly 11 can be fixed by the tight fit between the sealing plug 200 located inside the shell 100 and the shell 100.

[0034] In one embodiment, the top cover 300 is made of insulating material. Since the top cover 300 is at least partially located outside the housing 100, and the conductive column 500 and the pole portion 410 are inserted into the top cover 300, the top cover 300 is made of insulating material, which can reduce the problem of poor contact caused by accidental conduction between external factors and the conductive column 500 and / or the pole portion 410. For example, such a setting can reduce the probability of the leaked atomizable medium damaging the battery assembly 10 when the electronic atomization device leaks.

[0035] Furthermore, the top sleeve 300 may be made of a polymer material with certain deformable properties, such as a plastic material, so that the conductive pillar 500 and the top sleeve 300 can be interference-fitted. The sealing plug 200 and the top sleeve 300 may both be made of insulating materials to prevent the two conductive pillars 500 from short-circuiting.

[0036] Please refer to FIG. 2 and FIG. 3 . In one embodiment, a positioning surface 130 is provided at one end of the housing 100 close to the top sleeve 300 . The positioning surface 130 fits with the top sleeve 300 to improve the stability of the relative position of the two.

[0037] In one embodiment, the pole portion 410 may be a pole ear or a conductive pin. When the pole portion 410 is a conductive pin, the pole portion 410 may be directly conductively plugged with the conductive column 500. When the pole portion 410 is a pole ear, since the pole ear is softer than the conductive pin, a fixing device may be added to facilitate electrical connection between the pole ear and the conductive pin. For ease of understanding and description, the following description is based on the pole portion 410 being a conductive pin as an example.

[0038] Please refer to FIG. 1 to FIG. 3. In one embodiment, the energy storage member 400 includes a winding core 420, the pole portion 410 includes a positive pole portion 411 and a negative pole portion 412 both electrically connected to the winding core 420, and the conductive column 500 includes a positive pole column 501 conductively plugged with the positive pole portion 411, and a negative pole column 502 conductively plugged with the negative pole portion 412. The edge of the top sleeve 300 facing away from the sealing plug 200 is provided with a step 310, and the step 310 is used to be relatively fixed by being engaged with the battery rack 13, that is, the battery rack 13 can limit the top sleeve 300 through the step 310, so that the top sleeve 300 and the conductive column 500 inserted in the top sleeve 300 can be fixed relative to the housing 100. On the other hand, since the step 310 is provided at the edge of the top sleeve 300, the positive pole column 501 and the negative pole column 502 can be easily distinguished by using the step 310 as a reference, so as to achieve foolproof installation. For example, as shown in FIG. 2 , when viewed from the direction facing the step 310 , the positive pole 501 is located on the relatively left side (the viewing angle shown in FIG. 2 ), and the negative pole 502 is located on the relatively right side (the viewing angle shown in FIG. 2 ).

[0039] The winding core 420 includes a positive electrode sheet, a negative electrode sheet, and a separator. The winding core 420 may be formed by winding the positive electrode sheet, the negative electrode sheet, and the separator.

[0040] Please refer to FIG. 2 , in one embodiment, two limiting holes 12 may be provided at the top sleeve 300 to correspond to the positive electrode column 501 and the negative electrode column 502 respectively. A mark 330 for distinguishing the corresponding conductive column 500 is provided at the end surface of the top sleeve 300 corresponding to each limiting hole 12, that is, the positive electrode column 501 and the negative electrode column 502 can be quickly distinguished through the mark 330.

[0041] Please refer to Figures 2 and 3 again. In one embodiment, the housing 100 includes a neck 120. The sealing plug 200 is disposed on the neck 120. The neck 120 is concavely disposed to tightly abut the sealing plug 200. Thus, the sealing effect at the sealing plug 200 can be improved. Furthermore, the neck 120 can be concave in an arc shape.

[0042] In one embodiment, the sealing plug 200 may be roughly cylindrical. Alternatively, as shown in FIG. 2 and FIG. 3 , in another embodiment, the outer circumference of the sealing plug 200 is recessed to form a limiting groove 210, and the limiting groove 210 is continuously distributed along the circumference of the sealing plug 200, and the limiting groove 210 is limitedly matched with the inner concave wall of the neck 120. Since the limiting groove 210 forms a limiting match with the inner concave wall of the neck 120, the position stability of the sealing plug 200 can be improved. Moreover, compared with a regular cylindrical surface, the matching surface between the sealing plug 200 and the neck 120 is more complex, which can further improve the sealing effect of the sealing plug 200.

[0043] Please refer to FIG. 3 . In one embodiment, the limiting hole 12 includes a first hole 320 and a second hole 220. The first hole 320 is opened in the top sleeve 300, and the second hole 220 is opened in the sealing plug 200. The first hole 320 and the second hole 220 are coaxially arranged. The number of the first hole 320 and the second hole 220 corresponds to the number of the poles 410, that is, the first hole 320 and the second hole 220 can be both two, the two first holes 320 are spaced apart from each other, and the two second holes 220 are spaced apart from each other, so as to allow the positive pole 411 and the negative pole 412 to pass through, respectively, and the positive pole column 501 and the negative pole column 502 to pass through, respectively.

[0044] Furthermore, since the top cover 300 is made of insulating material, the positive electrode column 501 and the negative electrode column 502 passing through the top cover 300 can be insulated and isolated from each other to avoid short circuit.

[0045] As shown in FIG3 and FIG4, the conductive column 500 includes a conductive plug-in barrel 510 and a connecting portion 520. Both ends of the plug-in barrel 510 are hollow and are used to be plugged with the pole portion 410 and the electrical component respectively. The connecting portion 520 is connected to the plug-in barrel 510, and the connecting portion 520 at least partially protrudes from the outer periphery of the plug-in barrel 510, so that the connecting portion 520 and the first channel 320 are interference-fitted. In short, in this embodiment, the conductive column 500 achieves an interference fit with the top sleeve 300 through the protruding structure of the outer periphery.

[0046] Of course, in other embodiments, the inner wall of the first hole 320 may be provided with an interference ring (not shown) to achieve interference insertion between the first hole 320 and the conductive column 500. Alternatively, in another embodiment, the outer diameter of the conductive column 500 may be directly set to be larger than the inner diameter of the first hole 320 to achieve interference insertion. In the following embodiments, for ease of description, the conductive column 500 including the plug-in tube 510 and the connecting portion 520 is still used as an example for description.

[0047] Please continue to refer to Figure 3. In one embodiment, the first channel 320 includes a first hole segment 321 and a second hole segment 322 that are interconnected. The inner diameter of the second hole segment 322 is larger than the first hole segment 321, and the connecting portion 520 is interference fit with the second hole segment 322. The plug-in barrel 510 is interference fit with the first hole segment 321 at one end facing away from the energy storage member 400. Alternatively, the outer diameter of the plug-in barrel 510 is equal to the inner diameter of the first hole segment 321, and the plug-in barrel 510 is penetrated by the first hole segment 321. As a result, the inner wall of the first hole segment 321 can be supported on the outer periphery of the plug-in barrel 510, thereby improving the position stability of the conductive column 500. It should be noted that, since the connecting portion 520 is in the form of protruding from the outer periphery of the plug-in barrel 510 and having an interference fit with the first hole 320, the connecting portion 520 will form a gap between the hole wall of the first hole 320 and the plug-in barrel 510 while tightly abutting against the hole wall of the first hole 320, making the position of the plug-in barrel 510 unstable. In this embodiment, by providing the first hole section 321 and the second hole section 322 with different radial dimensions, the support of the top sleeve 300 to the plug-in barrel 510 can be achieved without weakening the interference fit. That is, the outer diameter of the plug-in barrel 510 can be greater than or equal to the inner diameter of the first hole section 321.

[0048] Furthermore, the top sleeve 300 is provided with a contact surface 323, which is located at the boundary between the first hole section 321 and the second hole section 322, and the contact surface 323 is in contact with the end surface of the connecting portion 520. Thus, when the conductive column 500 is inserted to a position in contact with the contact surface 323, it means that the conductive column 500 is plugged in place. In short, the contact surface 323 can be used to quickly know whether the conductive column 500 in the top sleeve 300 is plugged in place.

[0049] As shown in FIG. 3 , in one embodiment, the first hole section 321 may be arranged at a side away from the sealing plug 200 relative to the second hole section 322 .

[0050] In one embodiment, the pole part 410 can also be electrically connected to the conductive column 500 in the form of interference fit to improve the stability of electrical conduction. Further, as shown in Figures 3 and 4, the plug-in tube 510 includes a plurality of elastic claws 511 arranged at intervals along the circumference, and the elastic claws 511 surround and form an inner cavity 512 of the plug-in tube 510. When the pole part 410 is inserted into the inner cavity 512, the elastic claws 511 are spread open, so that the elastic claws 511 elastically clamp and electrically connect the pole part 410, so as to improve the stability of electrical conduction between the pole part 410 and the conductive column 500.

[0051] In one embodiment, the number of the elastic claw pieces 511 may be four.

[0052] Please continue to refer to FIG4 . In one embodiment, both sides of the connection portion 520 may be connected to plug-in barrels 510. There are two plug-in barrels 510. Both ends of the conductive column 500 are plugged in through the plug-in barrels 510. Since both ends of the conductive column 500 can be electrically connected in the form of plugging, as shown in FIG3 , the conductive column 500 can be completely disposed in the top sleeve 300.

[0053] The present application does not limit the connection method between the battery assembly 10 and the atomizer 20 provided in each embodiment, that is, the present application does not limit the specific form of the electronic atomization device. For example, the battery assembly 10 can be made into a housing with the atomizer 20 to form a disposable device, or it can be detachably connected with the atomizer 20 to enable the atomizer 20 or the battery assembly 10 to be replaced.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
