[0053] In one embodiment, as shown in Figure 2 and Figure 5As shown, the atomization main body comprises a liquid storage assembly 21 and a bracket 22, the liquid storage assembly 21 and the bracket 22 are sequentially arranged along the extension direction of the shell assembly 1, and the liquid storage assembly 21 is close to the top wall of the accommodating cavity; part of the first force transmission assembly 13 is arranged on the top wall of the accommodating cavity and abuts against one end of the liquid storage assembly 21 away from the bracket 22; the second force transmission assembly 14 is arranged on the side wall of the accommodating cavity and abuts against one end of the liquid storage assembly 21 close to the bracket 22, and / or one end of the bracket 22 close to the liquid storage assembly 21; one end of the bracket 22 away from the liquid storage assembly 21 abuts against the bottom wall of the accommodating cavity. It should be noted that in addition to the part of the first force transmission assembly 13 arranged on the top wall of the accommodating cavity, another part is arranged on the bottom wall of the accommodating cavity, and the first force transmission assembly 13 located on the bottom wall of the accommodating cavity can abut against the bracket 22 to realize the transmission of pressure.

[0054] In this embodiment, when the top wall of the shell assembly 1 is subjected to pressure, the first force transmission assembly 13 transmits part of the pressure received by the shell assembly 1 to the liquid storage assembly 21, the liquid storage assembly 21 transmits the pressure to the bracket 22, the bracket 22 transmits part of the pressure to the second force transmission assembly 14 for dispersion, and transmits another part of the pressure to the bottom wall of the shell assembly 1, thereby conducting and dispersing the pressure to prevent stress concentration in the middle part of the shell assembly 1.

[0055] In one embodiment, as shown in the accompanying drawings, Figure 3 The first force transmission assembly 13 comprises a plurality of first protruding portions 131, the plurality of first protruding portions 131 are protrudingly arranged at the middle position of one end of the accommodating cavity along the extension direction of the shell assembly 1; the liquid storage assembly 21 is provided with a plurality of first limiting grooves 2121 at the positions corresponding to the first protruding portions 131, at least one first protruding portion 131 is inserted into one first limiting groove 2121, and at least part of the first protruding portion 131 abuts against the groove wall of the first limiting groove 2121.

[0056] In this embodiment, since the liquid storage assembly 21 is provided with the first limiting groove 2121, the first protruding portion 131 is inserted into the first limiting groove 2121, and at least part of the first protruding portion 131 abuts against the groove wall of the first limiting groove 2121. In this way, on the one hand, since the first protruding portion 131 is inserted into the first limiting groove 2121, the first shell 11 and the second shell 12 can be prevented from being dislocated or loosened in the left-right direction to a certain extent. On the other hand, the contact area of the first protruding portion 131 and the liquid storage assembly 21 can be increased, thereby effectively dispersing the pressure, which is not only conducive to the effective transmission of pressure, but also can avoid damage to the liquid storage assembly 21 caused by stress concentration.

[0057] In one of the embodiments, the shell assembly 1 is further provided with a mounting hole 1111 for mounting the suction nozzle 3 of the atomization device; the first protruding portions 131 are arranged on the top wall of the accommodating cavity adjacent to the mounting hole 1111, and a plurality of the first protruding portions 131 are arranged at intervals on the periphery of the mounting hole 1111; the liquid storage assembly 21 comprises a first sealing member 212 and a liquid storage bin 211, the first sealing member 212 is sealingly connected between the liquid storage bin 211 and the suction nozzle 3 to enable the air passage between the liquid storage bin 211 and the suction nozzle 3, and the first sealing member 212 comprises a connecting portion sealingly connected with the suction nozzle 3, and a plurality of first limiting grooves 2121 are arranged at intervals on the periphery of the connecting portion.

[0058] In the product assembly process, the suction nozzle 3 is usually pressed into the mounting hole 1111 by a press, and in this process, the pressure acting on the suction nozzle 3 is transmitted to the shell assembly 1. When a plurality of the first protruding portions 131 are arranged at intervals on the periphery of the mounting hole 1111, and a plurality of the first limiting grooves 2121 are arranged at intervals on the periphery of the connecting portion of the first sealing member 212, the pressure can be better dispersed through the cooperation of the first protruding portions 131 and the first limiting grooves 2121, so that the pressure is uniformly transmitted from the top end of the shell assembly 1 to the bottom end of the shell assembly 1.

[0059] It should be noted that the number of the first limiting grooves 2121 is not limited in the embodiments of the present application, and can be adjusted according to actual needs by those skilled in the art. In one of the embodiments, the shell assembly 1 comprises a first shell 11 and a second shell 12 arranged opposite to each other along the first direction X and connected with each other, the first shell 11 comprises a first top wall 111, and the second shell 12 comprises a second top wall 121. The first protruding portions 131 are provided with eight, of which four first protruding portions 131 are arranged on the first top wall 111 and four first protruding portions 131 are arranged on the second top wall 121, and the first protruding portions 131 arranged on the first top wall 111 and the second top wall 121 are symmetrically arranged in the third direction Z. Correspondingly, the first limiting grooves 2121 are provided with four, of which two first limiting grooves 2121 correspond to the positions of the four first protruding portions 131 arranged on the first top wall 111, and the other two first limiting grooves 2121 correspond to the positions of the four first protruding portions 131 arranged on the second top wall 121, and adjacent two first protruding portions 131 are inserted into the same first limiting groove 2121, so that the number of the first limiting grooves 2121 can be reduced, and the processing difficulty of the liquid storage assembly 21 can be reduced.

[0060] In one of the embodiments, as shown in FIG. 1, Figure 3 and Figure 5As shown, the first force transmission assembly 13 further comprises at least two second protrusions 132 symmetrically arranged on the side wall of the accommodating cavity, and the second protrusions 132 abut against one end of the liquid storage container 211 away from the support 22. In one embodiment, two second protrusions 132 are arranged symmetrically on the side wall of the accommodating cavity. In this way, after the product is assembled, the second protrusions 132 can abut against one end of the liquid storage container 211 away from the support 22, so that the liquid storage container 211 can be reliably limited from both sides.

[0062] In this embodiment, since the third protrusions 133 are arranged and abut against the circuit board 23 and / or the support 22, a part of the pressure transmitted from the liquid storage assembly 21 to the support 22 can be sequentially transmitted to the bottom wall of the accommodating cavity through the circuit board 23 and / or the third protrusions 133, thereby achieving smooth transmission of pressure from top to bottom, effectively avoiding plastic deformation of the middle part of the shell assembly 1 due to pressure concentration, and preventing the problem of disconnection of the shell assembly 1. In one embodiment, as shown in Figures 6-7 the third protrusions 133 are arranged in three, two of which are arranged on the first bottom wall 112, and the other is arranged on the second bottom wall 122. The two third protrusions 133 arranged on the first bottom wall 112 abut against the circuit board 23, and the third protrusion 133 arranged on the second bottom wall 122 abuts against the support 22. In this way, the pressure transmitted to the support assembly can be dispersed, a part of the pressure is transmitted to the second bottom wall 122 through the support 22 and the third protrusion 133, and the other part of the pressure is transmitted to the first bottom wall 112 through the circuit board 23 and the third protrusion 133, which is beneficial to uniform stress of the first shell 11 and the second shell 12. In addition, the support 22 forms an air channel and a mounting cavity, one end of the air channel communicates with the atomization core arranged in the liquid storage assembly 21, and the other end of the air channel communicates with the external atmosphere. The atomization main body 2 further comprises a battery 24 arranged in the mounting cavity and electrically connected with the circuit board 23, and the circuit board 23 is connected with the atomization core, thereby providing working voltage for the atomization core to atomize the atomization substrate stored in the liquid storage assembly 21 into aerosol.

[0063] In one embodiment, as shown in Figure 8As shown, the bracket 22 comprises a third bottom wall 222, and the third bottom wall 222 is provided with a sixth protruding part 224 on the side away from the third top wall 221, and the sixth protruding part 224 abuts against the bottom wall of the accommodating cavity and / or the third protruding part 133. The bottom wall of the accommodating cavity comprises the first bottom wall 112 of the first shell 11 and the second bottom wall 122 of the second shell 12. In this way, part of the pressure transmitted from the liquid storage assembly 21 to the bracket 22 can be transmitted to the bottom wall of the accommodating cavity through the sixth protruding part 224 and the third protruding part 133 in sequence, or transmitted to the bottom wall of the accommodating cavity through the sixth protruding part 224 in sequence, so as to realize smooth transmission of pressure from top to bottom, effectively avoid plastic deformation of the middle part of the shell assembly 1 caused by pressure concentration, and prevent the problem of disconnection of the shell assembly 1.

[0064] It should be noted that the specific structure and number of the sixth protruding part 224 are not limited in the embodiments of the present application, and those skilled in the art can adjust them according to actual needs. In one of the embodiments, the sixth protruding part 224 is provided with three sixth protruding parts, one of which abuts against the third protruding part 133 provided on the second bottom wall 122, and the other two sixth protruding parts 224 abut against the second bottom wall 122, so as to effectively transmit part of the pressure transmitted to the bracket 22 to the second bottom wall 122.

[0065] In one of the embodiments, as shown in the accompanying drawings, Figure 6 The bracket 22 comprises a third top wall 221 close to the liquid storage assembly 21, and the second force transmission assembly 14 comprises at least two fourth protruding parts 141, which are arranged on the side wall of the accommodating cavity along the circumference of the shell assembly 1 and abut against one end of the third top wall 221 away from the liquid storage assembly 21.

[0066] In this embodiment, the fourth protruding part 141 is arranged and abuts against the third top wall 221 of the bracket 22. In this way, on the one hand, the fourth protruding part 141 can support and fix the bracket 22 and the liquid storage assembly 21 located above the bracket 22; on the other hand, the bracket 22 can transmit part of the pressure to the fourth protruding part 141 located between the first protruding part 131 and the third protruding part 133 for dispersion, so as to further optimize the force transmission path and make the pressure be transmitted uniformly and effectively, so as to avoid the pressure concentration in the middle part of the shell assembly 1.

[0067] It should be noted that the number of the first protruding portion 131, the third protruding portion 133 and the fourth protruding portion 141 is not limited in the embodiments of the present application, and can be adjusted according to actual needs by those skilled in the art. It can be understood that when the first protruding portion 131, the third protruding portion 133 and the fourth protruding portion 141 are all provided with multiple protruding portions, the stress concentration phenomenon can be effectively dispersed and reduced. In addition, the first shell 11 includes the first side wall 113, and the second shell 12 includes the second side wall 123. The present application only shows the case that the fourth protruding portion 141 is arranged on the first side wall 113, but in actual application, the fourth protruding portion 141 can also be arranged only on the second side wall 123, or arranged on the first side wall 113 and the second side wall 123 at the same time, which is not limited herein, and can be adjusted according to actual needs by those skilled in the art.

[0068] In an embodiment, the bracket 22 further includes a third side wall 223, which is arranged on the side of the third top wall 221 away from the bracket. The fourth protruding portion 141 includes an end abutting segment close to the edge of the first shell 11, which extends towards the direction close to the second shell 12 and abuts against the third side wall 223. In addition, the fourth protruding portion 141 includes an end abutting segment close to the edge of the second shell 12, which extends towards the direction close to the first shell 11 and abuts against the third side wall 223.

[0069] In this embodiment, taking the fourth protruding portion 141 arranged on the first side wall 113 as an example, the fourth protruding portion 141 close to the edge of the first side wall 113 (i.e. the fourth protruding portion 141 located on the left side in the figure) extends towards the direction of the second side wall 123 and abuts against the third side wall 223. In this way, on the one hand, the movement of the bracket 22 in the left-right direction can be limited, thereby improving the connection stability of the shell assembly 1 and the bracket 22. On the other hand, when the atomization device is stressed in the left-right direction, the two fourth protruding portions 141 located on the left and right sides can transmit the stress of the shell assembly to the bracket 22 in the left-right direction, thereby avoiding the local deformation of the shell assembly caused by stress concentration. Figure 2

[0070] In an embodiment, the fourth protruding portion 141 is provided with two fourth protruding portions 141, which are arranged on the first side wall 113 and symmetrically distributed in the length direction of the shell (i.e. the third direction Z). By abutting the fourth protruding portion 141 against the third top wall 221 of the bracket 22, the transmission of pressure in the up-down direction can be realized. At the same time, the end abutting segment of the fourth protruding portion 141 can abut against the third side wall 223 of the bracket 22, thereby realizing the transmission of pressure in the left-right direction.

[0071] In an embodiment, as shown in Figure 6 ​As shown, the second force transmission assembly 14 further comprises a plurality of fifth protrusions 142 extending along the circumference of the shell assembly 1 and symmetrically arranged on the side wall of the accommodating cavity, and each of the fifth protrusions 142 abuts against the opposite sides of the liquid storage assembly 21. On one hand, the fifth protrusions 142 can not only enhance the structural strength of the shell assembly 1, so as to better resist deformation, but also provide additional support points, so as to improve the connection stability of the shell and the atomization main body 2. On the other hand, since the plurality of fifth protrusions 142 abut against the opposite sides (including the left and right sides and / or the front and back sides) of the liquid storage assembly 21, when the shell assembly 1 is subjected to force in the left-right direction or the front-back direction, the fifth protrusions 142 can also transmit the force of the shell to the left and right or the front and back through the liquid storage assembly 21, so as to avoid local deformation of the shell caused by stress concentration.
