[0030] In one embodiment, please refer to Figure 2 and Figure 3, the accommodating chamber 231 is located on the bracket 23, the accommodating chamber 231 has an opening facing the second direction, the second direction intersects with the first direction, the second direction can be set to be perpendicular to the first direction, and in other embodiments, the angle between the first direction and the second direction can be set to be an acute angle or an obtuse angle, the battery 21 is located in the accommodating chamber 231, the atomizer assembly 1 is located outside the accommodating chamber 231, the atomizer assembly 1 and the accommodating chamber 231 are arranged in the first direction, the size of the atomizer assembly 1 in the first direction is smaller than the size of the bracket 23 in the first direction, and it can also be understood that the atomizer assembly 1 and the bracket 23 are partially arranged in the second direction; the bracket 23 has a first direction located in the accommodating chamber 231. The first side wall 232 and the second side wall 233 of the accommodating chamber wall are formed on both sides of the cavity 231. The first side wall 232 is located on the side of the accommodating chamber 231 facing away from the atomizer assembly 1 in the first direction. The second side wall 233 is located between the accommodating chamber 231 and the atomizer assembly 1 in the first direction. The second side wall 233 has a second side facing the atomizer assembly 1 in the first direction. The bracket 23 also has a mounting structure for mounting the atomizer assembly 1. The mounting structure protrudes from the second side of the second side wall 233 in the first direction. The second side wall 233 of the bracket 23 cooperates with the atomizer assembly 1 through the mounting structure, which helps to fix the position of the atomizer assembly 1 in the shell 24.

[0031] In one embodiment, please refer to Figure 2 and Figure 3 The mounting structure includes two grooves 2331 with opposite notches, the groove 2331 is a slot, the slot has the slot direction perpendicular to the notch direction of the two grooves 2331, the mounting structure also includes a positioning protrusion 2332, the positioning protrusion 2332 has a supporting surface facing opposite to the slot direction of the groove 2331; the atomizer assembly 1 has a protrusion for matching with the slot and a supporting portion that abuts against the positioning protrusion 2332, the supporting portion having a supporting matching surface facing the same direction as the slot; the protrusion of the atomizer assembly 1 slides into the slot in a direction opposite to the slot direction to achieve the matching of the protrusion slot, and after the protrusion and the slot are matched in place, the supporting matching surface of the supporting portion and the supporting surface of the positioning protrusion 2332 abut against each other in the direction of the slot to achieve the connection and fixation of the atomizer assembly 1 and the bracket 23; and the mounting structure as a whole protrudes from the second side surface of the second side wall 233, which helps to increase the structural strength of the second side wall 233.

[0032] In another embodiment, the bracket may not be provided with a mounting structure, and the atomizer assembly 1 is clamped and fixed in the housing 24 in the first direction only by the second side wall 233 and the end cover 25 .

[0033] In one embodiment, please refer to Figure 2 and Figure 3The first side wall 232 of the bracket 23 extends in a plane perpendicular to the first direction, and the first end surface of the bracket 23 that cooperates with the shell 24 is located on the first side wall 232; the bracket 23 has a pressure relief hole 2321 that connects the accommodating chamber 231 with the external space of the shell, and the pressure relief hole 2321 is located on the first side wall 232. The pressure relief hole 2321 connects the accommodating chamber 231 with the first opening 241. By providing the pressure relief hole 2321, the structural strength of the first side wall 232 can be reduced, so that the structural strength of the first side wall 232 is less than the structural strength of the second side wall 233. In this way, when the battery 21 explodes during use, the energy in the explosion process can be discharged from the pressure relief hole 2321 on the first side wall 232. Since the pressure relief hole 2321 is located on the side of the accommodating chamber 231 that is away from the atomizer assembly 1, the explosion energy is discharged in the direction away from the atomizer assembly 1. In this way, the impact force of the battery 21 during the explosion process is discharged from the pressure relief hole 2321 in the direction away from the user, which helps to reduce the damage to the user caused by the explosion of the battery 21.

[0034] In one embodiment, please refer to Figure 2 and Figure 3 The power supply assembly further includes a protective member 26, which may be a rubber member, such as a silicone sheet. Of course, in other embodiments, it may also be a plastic member or a rigid member. The silicone sheet is located on the side of the bracket 23 facing away from the end cover 25 in the first direction. The silicone sheet is connected to the first side wall 232 of the bracket 23 by gluing, and the silicone sheet blocks the first opening 241 of the housing 24. The silicone sheet corresponds to the pressure relief hole 2321 in the first direction to cover the pressure relief hole 2321. On the one hand, this can ensure the consistency of the appearance of the entire atomizer during normal use of the atomizer, and can also be used through the silicone The film covers the pressure relief hole 2321 on the first side wall 232 to prevent external dust and small particles from entering the accommodating cavity 231 along the pressure relief hole 2321 and affecting the normal operation of the power supply component; on the other hand, the structure of the pressure relief hole 2321 covered by the silicone sheet glued to the bracket 23 can allow the energy of the explosion process to break open the entire silicone sheet during the explosion of the battery 21, and utilize the adhesion between the silicone sheet and the bracket 23 and the characteristics of the silicone sheet itself under force and deformation to buffer and reduce the impact force and energy rushing out of the first opening 241 during the explosion, thereby further reducing the damage to users caused by the explosion of the battery 21.

[0035] Of course, in other embodiments, the silicone sheet can also be fixed to the first side wall 232 of the bracket 23 by means of screw connection, or be connected to the housing 24 by means of gluing, screw connection or interference fit, so as to block the first opening 241 and cover the pressure relief hole 2321 through the silicone sheet, and buffer the impact force and energy during the explosion of the battery 21 through the deformation of the silicone sheet.

[0036] In an embodiment where the protective member 26 is a plastic member or a rigid member, the protective member 26 can also be installed on the housing 24 through a torsion spring. Under the elastic force of the torsion spring, the protective member 26 blocks the first opening 241 and covers the pressure relief hole 2321. The impact force and energy when the battery 21 explodes can overcome the elastic force of the torsion spring to allow the protective member 26 to rotate relative to the rotating shaft of the torsion spring, open the first opening 241 and the pressure relief hole 2321, and discharge the impact force and energy from the first opening 241 and the pressure relief hole 2321.

[0037] In one embodiment, please refer to Figure 2 and Figure 3 The pressure relief hole 2321 on the first side wall 232 is relatively large in size. In order to prevent the silicone member from being sunken at the position of the pressure relief hole 2321, the power supply assembly is provided to further include a blocking member 27. The pressure relief hole 2321 is a circular hole. The blocking member 27 is installed at an end of the pressure relief hole facing away from the accommodating cavity 231 in the first direction. The blocking member 27 blocks the pressure relief hole. The blocking member 27 is a circular sheet structure that matches the shape of the pressure relief hole 2321. At least a portion of the blocking member 27 is located in the pressure relief hole 2321. The outer peripheral surface of the blocking member 27 cooperates with the hole wall surface of the pressure relief hole 2321. There is no fixed connection relationship between the blocking member 27 and the bracket 23. The blocking member 27 has an outer side surface facing away from the atomizer assembly 1 in the first direction. The outer side surface of the blocking member 27 abuts against the silicone member in the first direction. The blocking member 27 is clamped between the battery 21 and the silicone member in the first direction. The blocking member 27 supports the silicone member at the position of the pressure relief hole 2321 to prevent the silicone member from being recessed at the position of the pressure relief hole 2321.

[0038] In one embodiment, please refer to Figure 2 and Figure 3 The blocking member 27 and the first side wall 232 of the bracket 23 are abutted against each other in the first direction. The blocking member 27 has a first abutting surface 271 facing the accommodating cavity 231 in the first direction. The inner wall surface of the pressure relief hole 2321 has a second abutting surface 2322 facing away from the accommodating cavity 231 in the first direction. The first abutting surface 271 and the second abutting surface 2322 abut against each other in the first direction, which facilitates the installation of the blocking member 27 and can prevent the blocking member 27 from entering the accommodating cavity 231 along the first direction during the installation process.

[0039] In another embodiment, the outer peripheral surface of the sealing member 27 and the inner wall surface of the pressure relief hole 2321 can be arranged to be part of a conical surface, and the inner wall surface of the pressure relief hole 2321 and the outer peripheral surface of the sealing member 27 can be abutted against each other in a first direction. This facilitates the installation of the sealing member 27 and can also prevent the sealing member 27 from entering the accommodating cavity 231 along the first direction during the installation process.

[0040] In one embodiment, please refer to Figure 2The first side wall 232 has a first side surface facing away from the atomizer assembly 1 in the first direction. The first side surface is also an end surface of the bracket 23 in the first direction. The outer side surface of the blocking member 27 and the first side surface are both planes. After the blocking member 27 is installed in the pressure relief hole 2321, the outer side surface of the blocking member 27 is flush with the first side surface. This can prevent the silicone member from being recessed at the pressure relief hole 2321 and from bulging at the pressure relief hole 2321, which helps to ensure the consistency of the appearance of the entire atomizer device.

[0041] Of course, in the embodiment where there is a gap between the first side wall 232 and the protective member 26, the outer side surface of the blocking member 27 can also be arranged to slightly protrude from the first side surface, as long as the assembly of the protective member 26 can be achieved and after assembly, it can be ensured that the protective member 26 does not bulge at the position of the pressure relief hole 2321.

[0042] In another embodiment, there are multiple pressure relief holes 2321 on the first side wall 232, and the multiple pressure relief holes 2321 have different structural shapes, and two adjacent pressure relief holes 2321 are arranged at intervals, so that the multiple pressure relief holes 2321 form a hollow structure, and the setting of the blocking member 27 in the power supply assembly can be cancelled. In this way, since the size of each pressure relief hole 2321 is small, the silicone member will not be recessed at the position of the pressure relief hole 2321. Of course, in the embodiment where the protective member 26 is a plastic member or a rigid member, the blocking member 27 may not be provided.

[0043] In one embodiment, please refer to Figure 2 and Figure 3 The circuit board 22 is arranged to extend along the first direction, the circuit board 22 and the battery 21 are arranged in the second direction, the circuit board 22 is located in the housing 24, the circuit board 22 is located at the opening of the accommodating cavity 231, and the circuit board 22 and the battery 21 are attached in the second direction so as to block the opening of the accommodating cavity 231 through the circuit board 22; a positioning protrusion 2351 facing the circuit board 22 is provided on the bracket 23, the bracket 23 has a third side wall 234 and a fourth side wall 235 located on both sides of the accommodating cavity 231 in the second direction to form a cavity wall of the accommodating cavity, the positioning protrusion 2351 is located on the third side wall 234 and the fourth side wall 235 of the accommodating cavity 231, and the corresponding edge position of the circuit board 22 has a positioning groove 221 that is positioned and matched with the positioning protrusion 2351, the positioning groove 221 cooperates with the positioning protrusion 2351, and the circuit board 22 and the battery 21 are attached to realize the positioning of the circuit board 22 in the housing 24; in this way, the impact force and energy discharged from the opening of the accommodating cavity 231 when the battery 21 explodes can be blocked to a certain extent by the circuit board 22. In addition, the shell 24 can be made of metal material. The side walls of the shell 24 can block the impact force and energy of the battery 21 when it explodes, thereby preventing the impact force and energy of the battery 21 from pouring in the vertical first direction, thereby reducing the damage to the user caused by the battery 21 explosion.

[0044] In another embodiment, the size of the circuit board 22 can be set smaller than the opening size of the accommodating cavity 231, so that the opening of the accommodating cavity 231 is an open structure, and only the shell 24 made of metal material is used to block the impact force and energy when the battery 21 explodes, which can also reduce the harm to the user caused by the explosion of the battery 21.

[0045] In one embodiment, the atomizer needs to undergo a drop test, which places high requirements on the connection relationship and relative position between the components in the atomizer housing 24. In order to avoid poor contact of the power supply component after the drop test, the power supply component is provided to include a binding flexible member (not shown in the figure). The binding flexible member may be an insulating tape or a rope. The binding flexible member is wound around the bracket 23 and the battery 21 in a first direction to achieve the positioning of the battery 21 in the accommodating cavity 231. A sponge or foam 28 may also be provided between the side wall of the accommodating cavity 231 and the battery 21 to cushion the impact of the bracket 23 on the battery 21, thereby increasing the probability of the atomizer passing the drop test.

[0046] Furthermore, the bracket 23 has a notch 236 connected to the accommodating cavity 231, so that part of the binding flexible member passes through the notch 236 and contacts the battery 21 in the accommodating cavity 231. If the binding flexible member is an insulating tape, the insulating tape passes through the notch 236 and adheres to the battery 21, which can fix the position of the battery 21 in the accommodating cavity 231.

[0047] Since the circuit board 22 blocks the opening of the accommodating cavity 231 , a binding flexible member may be provided to wrap around the outside of the circuit board 22 , the bracket 23 and the battery 21 to achieve relative fixation of the positions of the circuit board 22 , the battery 21 and the bracket 23 .

[0048] In one embodiment, a notch 236 is arranged opposite to the opening of the accommodating cavity 231 in the second direction, so that the relative positions of the circuit board 22, the battery 21 and the bracket 23 in the second direction can be ensured to avoid poor contact between the circuit board 22 and the battery 21.

[0049] Of course, in another embodiment, it is also possible to dispose the notch 236 on the third side wall 234 and / or the fourth side wall 235 of the accommodating cavity 231 .

[0050] In one embodiment, the housing of the power supply assembly can also be integrally formed, such as the bracket 23 of plastic material and the housing 24 of metal material can be injection molded by overmolding, which requires that the openings of the housing 24 at both ends in the first direction are larger to ensure that the battery 21 can be installed in the accommodating cavity 231. Alternatively, in some other embodiments, the housing 24 can also be made of a plastic material with higher strength, and the housing 24 and the bracket 23 are integrally formed.

[0051] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
