Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0038] Please refer to Figures 1-4 The present application provides a jig 1 for fixing a battery assembly 2, which is suitable for the assembly process of assembling the battery assembly 2 into a tubular shell 3. The atomization device refers to an electronic atomization device including a power supply device and an atomization device, which supplies power to the atomization device through the power supply device, so that the atomization device heats the liquid to be atomized to generate atomized gas for the user to suck. The battery assembly 2 includes a bracket 21 and components such as a battery 22 and a microphone silica gel (not shown in the figure) arranged in the bracket, and the battery assembly 2 is used to be assembled into the tubular shell 3 to form a combined device with the tubular shell 3, which is the main part of the power supply device of the atomization device. One end of the battery assembly 2 is provided with a soft rubber sealing element 23, which is used to seal the gap between the battery assembly 2 and the tubular shell 3. Specifically, in the present embodiment, the soft rubber sealing element 23 is a silica gel sealing seat. When the battery assembly 2 is assembled into the tubular shell 3, the silica gel sealing seat can play a sealing role to ensure the airtightness of the combined device.

[0039] The jig 1 comprises a rod-shaped portion 11 and an abutting portion 13 arranged at one end of the rod-shaped portion 11. The abutting portion 13 is made of a hard material, for example, the abutting portion 13 can be made of hard plastic. The abutting portion 13 is arranged to abut against an end surface of the soft rubber seal 23 and to form a pluggable fixed connection with the soft rubber seal 23. The end surface of the abutting portion 13 has the same shape as the end surface of the soft rubber seal 23 so that the abutting portion 13 can completely cover the end surface of the soft rubber seal 23.

[0040] As can be easily understood, because the abutting portion 13 is made of a hard material, the end surface of the abutting portion 13 completely covers the end surface of the soft rubber seal 23, and the abutting portion 13 abuts against the end surface of the soft rubber seal 23 and forms a fixed connection with the soft rubber seal 23, therefore, when the combined device composed of the battery assembly 2 and the tubular housing 3 is assembled into the tubular housing 3, the abutting portion 13 can protect the soft rubber seal 23 from being squeezed, thereby avoiding the elastic deformation of the soft rubber seal 23, and thereby avoiding the undesirable phenomenon of the soft rubber seal 23 being turned up or falling off.

[0041] In the embodiment, the cross-sectional dimension of the rod-shaped portion 11 is arranged to be smaller than the cross-sectional dimension of the abutting portion 13, so as to ensure that the jig 1 can be smoothly taken out by grabbing the rod-shaped portion 11 after the assembly is completed.

[0042] In the embodiment, the end surface of the abutting portion 13 has the same shape as the cross-sectional shape of the inner cavity of the tubular housing 3. Because the end surface of the abutting portion 13 has the same shape as the cross-sectional shape of the inner cavity of the tubular housing 3, the abutting portion 13 will slide along the inner side wall of the inner cavity of the tubular housing 3 during the assembly process. Because the end surface of the abutting portion 13 has the same shape as the end surface of the soft rubber seal 23, the sliding process of the abutting portion 13 in the inner cavity of the tubular housing 3 can be completely equivalent to the sliding process of the soft rubber seal 23 in the inner cavity of the tubular housing 3 when the battery assembly 2 is directly assembled into the tubular housing 3, thereby ensuring that the position of the combined device assembled into the tubular housing 3 is the same as the position of the battery assembly 2 directly assembled into the tubular housing 3.

[0043] The tool 1 provided by the embodiment of the present application can completely cover the end face of the soft rubber seal 23 after the abutting portion 13 abuts against the end face of the soft rubber seal 23, and the abutting portion 13 and the soft rubber seal 23 are formed in a pluggable fixed connection, so that in the assembling process of assembling the battery assembly 2 into the tubular shell 3, the combined device formed by connecting the battery assembly 2 and the tool 1 can be assembled into the tubular shell 3, and then the tool 1 can be taken out outwardly, and because the end face of the abutting portion 13 has the same shape as the end face of the soft rubber seal 23, the assembling position of the tool 1 in the tubular shell 3 is the same as that of the battery assembly 2; and because the end face of the abutting portion 13 has the same shape as the cross-sectional shape of the inner cavity of the tubular shell 3, and the abutting portion 13 is made of hard material, the shape of the soft rubber seal 23 can be fixed by the abutting portion 13, so that the soft rubber seal 23 is prevented from being elastically deformed to cause the phenomenon of flanging or falling off due to extrusion during the assembling process; and because the cross-sectional size of the rod-shaped portion 11 is smaller than that of the abutting portion 13, the tool 1 can be conveniently taken out outwardly by grabbing the rod-shaped portion 11 after the combined device is assembled into the tubular shell 3, so as to complete the assembling.

[0044] In an embodiment, the tool 1 further comprises a transition portion 12 arranged between the rod-shaped portion 11 and the abutting portion 13, and the transition portion 12 has a circular truncated cone shape with a gradually increasing radius from the rod-shaped portion 11 to the abutting portion 13. By arranging the transition portion 12, the overall shape of the tool 1 is easier to process, and the rigidity and strength of the tool 1 during use can be better guaranteed.

[0045] In an embodiment, the end face of the abutting portion 13 is provided with a clamping groove 131, and the end face of the soft rubber seal is provided with a clamping protrusion 231, and the abutting portion 13 and the soft rubber seal 23 are connected in a pluggable fixed connection through the clamping cooperation of the clamping protrusion 231 and the clamping groove 131.

[0046] It is easily understood that because the abutting portion 13 is provided with the clamping groove 131, and the soft rubber seal 23 is provided with the clamping protrusion 231, when the abutting portion 13 abuts against the end face of the soft rubber seal 23, the clamping protrusion 231 is inserted into the clamping groove 131, so that the abutting portion 13 and the soft rubber seal 23 can be connected in a pluggable fixed connection.

[0047] In an embodiment, the clamping groove 131 is an annular groove arranged around the central axis of the abutting portion 13; and the clamping protrusion 231 is an annular protrusion arranged around the central axis of the soft rubber seal 23.

[0048] It is easy to understand that by setting the clamping protrusion 231 and the clamping groove 131 as annular, the abutting of the abutting portion 13 and the soft rubber seal 23 can be more uniform and complete.

[0049] In an embodiment, the end surface of the soft rubber seal 23 is provided with a first magnetic attraction contact 232, and the end surface of the abutting portion 13 is provided with a second magnetic attraction area 132 corresponding to the first magnetic attraction contact 232 and capable of forming a magnetic attraction connection with the first magnetic attraction contact 232. By setting the first magnetic attraction contact 232 and the second magnetic attraction area 132, the end surface of the abutting portion 13 can be automatically magnetically connected to the end surface of the soft rubber seal 23 when the jig 1 is used, and the end surface of the abutting portion 13 can be automatically abutted on the end surface of the soft rubber seal 23.

[0050] In other embodiments, the end surface of the abutting portion 13 is provided with a second magnetic attraction contact corresponding to the first magnetic attraction contact 232, and the end surface of the abutting portion 13 can also be automatically magnetically connected to the end surface of the soft rubber seal 23 when the jig 1 is used.

[0051] In an embodiment, the end surface of the soft rubber seal 23 is provided with two or more first magnetic attraction contacts 232 evenly spaced around the center of symmetry thereof, and the end surface of the abutting portion 13 is provided with two or more second magnetic attraction areas 132 evenly spaced around the center of symmetry thereof. By setting multiple first magnetic attraction contacts 232 and corresponding multiple second magnetic attraction areas 132, the first magnetic attraction contacts 232 and the second magnetic attraction areas 132 can be automatically aligned magnetically during the abutting of the abutting portion 13 to the end surface of the soft rubber seal 23, so that the clamping protrusion 231 and the clamping groove 131 can also be automatically aligned, and the automatic connection of the abutting portion 13 and the soft rubber seal 23 can be achieved.

[0052] Specifically, in the present embodiment, the end surface of the soft rubber seal 23 is provided with two first magnetic attraction contacts 232 evenly spaced around the center of symmetry thereof, and the end surface of the abutting portion 13 is provided with two second magnetic attraction areas 132 evenly spaced around the center of symmetry thereof. Setting two first magnetic attraction contacts 232 and two second magnetic attraction areas 132 can not only achieve the automatic alignment function, but also save costs and avoid waste of resources to the greatest extent.

[0053] In an embodiment, the end surface of the soft rubber seal 23 is provided with an electrode contact 233 for outputting electrical energy to the outside, and the end surface of the abutting portion 13 is provided with a first avoiding groove 133 for accommodating the electrode contact 233. By setting the first avoiding groove 133, the abutting of the abutting portion 13 and the soft rubber seal 23 and the pluggable fixed connection can be avoided because the electrode contact 233 is protrudingly arranged on the end surface of the soft rubber seal 23.

[0054] In an embodiment, the end surface of the soft rubber seal 23 is provided with a ring-shaped air passage 234 for communication with the outside, and the end surface of the abutting portion 13 is provided with a second avoiding groove 134 for accommodating the ring-shaped air passage 234. By providing the second avoiding groove 134, the abutting of the abutting portion 13 and the soft rubber seal 23 and the pluggable fixed connection can be avoided due to the protruding ring-shaped air passage 234 provided on the end surface of the soft rubber seal 23.

[0055] In addition, referring to Figure 5 The embodiment of the present application also provides a use method of the jig 1, which comprises the following steps:

[0056] S1, using the above-mentioned jig 1, the end surface of the abutting portion 13 of the jig 1 is abutted and connected to the end surface of the soft rubber seal 23 to form a combined device;

[0057] S2, the combined device is pushed into the tubular shell 3 through the opening at one end of the tubular shell 3 to realize the assembly of the combined device and the tubular shell 3;

[0058] S3, the jig 1 is taken out outwardly by grabbing the rod-shaped portion 11 of the jig 1.

[0059] The use method of the jig 1 provided by the embodiment of the present application can also avoid the adverse phenomenon of the elastic deformation of the soft rubber seal 23 due to the extrusion in the assembly process, and the flanging or falling off, because the assembly of the battery assembly 2 and the tubular shell 3 is realized by using the above-mentioned jig 1 and adopting the alternative assembly method of assembling the combined device formed by connecting the battery assembly 2 and the jig 1 into the tubular shell 3 and then taking the jig 1 outwardly; and the jig 1 is taken out outwardly by grabbing the rod-shaped portion 11, which is convenient to operate.

[0060] The specific method of step S3 comprises: using an automatic mechanical arm to automatically clamp the rod-shaped portion 11 of the jig 1 to take the jig 1 outwardly.

[0061] It is easy to understand that the rod-shaped portion 11 of the jig 1 can be clamped by the existing automatic mechanical arm, so as to facilitate the realization of automatic assembly processing, improve the production efficiency and guarantee the cleanliness and other production requirements in production.

[0062] After step S3, the following steps are further included:

[0063] S4, checking whether the assembly effect of the battery assembly 2 and the tubular shell 3 meets the assembly requirements;

[0064] S5, for the battery assembly 2 that does not meet the assembly requirements, the end surface of the abutting portion of the jig 1 is pressed onto the end surface of the soft rubber seal 23 again;

[0065] S6, the jig 1 is taken out and the assembly effect of the battery assembly 2 and the tubular shell 3 is re-inspected to see if it meets the assembly requirements. If it does not, the steps S5-S6 are repeated until the assembly effect of the battery assembly 2 and the tubular shell 3 meets the assembly requirements.

[0066] It is easily understood that through the steps S4-S6, the assembly effect of the battery assembly 2 and the tubular shell 3 is inspected to avoid affecting the finished atomization device due to unqualified assembly, and through the repeated steps S5-S6, the soft rubber seal 23 of the battery assembly 2 that was unqualified in the last assembly can be profiled and tightly pressed to correct the soft rubber seal 23 to the shape when the assembly is qualified, which fully utilizes the jig 1 of the above embodiment to ensure that the shape of the soft rubber seal of the battery assembly 2 meets the assembly requirements.

[0067] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
