Therefore, they should not be understood as limitations on the present application.

[0027] It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] like Figure 1 As shown, an embodiment of the present application discloses an electronic atomization device, wherein the electronic atomization device 10 includes a bottom air regulating structure 100, an atomizer 200 and a shell 300, wherein the bottom air regulating structure 100 is fixed to the bottom of the shell 300, and the atomizer 200 is fixed to the top of the shell 300, and the bottom air regulating structure 100 supplies power to the atomizer 200 to control the operation of the heating element in the atomizer 200.

[0029] Combination Figure 1 , Figure 2 and Figure 3As shown, the bottom air regulating structure 100 includes a base 130, a bracket 120 and a USB plug board 110. The base 130 and the bracket 120 are hollow inside, the USB plug board 110 is arranged inside the bracket 120, and the base 130 is sleeved outside the bracket 120; that is, from the inside to the outside, the USB plug board 110, the bracket 120 and the base 130 are distributed in sequence.

[0030] The USB plug board 110 includes a circuit board 111 and a USB socket 112. The USB socket 112 is vertically arranged to the circuit board 111. One end of the USB socket 112 is connected to one side of the circuit board 111, and the other end of the USB socket 112 faces the bottom of the bracket 120. The bottom of the bracket 120 is provided with a first opening 121, and the bottom of the base 130 is provided with a second opening 131. The first opening 121, the second opening 131 and the positive projection of the USB socket 112 overlap, that is, the USB socket 112 is exposed at the bottom of the product. The first opening 121 and the second opening 131 are equivalent to the air avoidance design on the bracket 120 and the base 130.

[0031] Combination Figure 3 and Figure 4 As shown, the circuit board 111 is provided with a first air inlet 113, the side wall of the bracket 120 is provided with a second air inlet 122, and the side wall of the base 130 is provided with a third air inlet 132. The first air inlet 113, the second air inlet 122 and the third air inlet 132 form a connected air passage, one end of the air passage is exchanged with the outside air through the third air inlet 132, and the other end of the air passage enters the atomizer 200 and the mouthpiece through the first air inlet 113.

[0032] The outer wall of the bracket 120 is provided with a first sliding portion 123, and the inner wall of the base 130 is provided with a second sliding portion 133 that cooperates with the first sliding portion 123. The first sliding portion 123 extends in a direction surrounding the central axis of the bracket 120, and the second sliding portion 133 extends in a direction surrounding the central axis of the base 130. The base 130 and the bracket 120 are connected by sliding of the first sliding portion 123 and the second sliding portion 133 to achieve relative rotation.

[0033] It can be understood that in the embodiment of the present application, the bracket 120 and the base 130 are both axisymmetric structures, and the cross-sections are both circular, and the bracket 120 and the base 130 both have a central axis; of course, the bracket 120 and the base 130 may not be axisymmetric structures, in which case the first sliding portion 123 and the second sliding portion 133 may extend in the direction of the central axis of the housing 300. After the first sliding portion 123 and the second sliding portion 133 cooperate, the first sliding portion 123 and the second sliding portion 133 can slide relative to each other, so that the base 130 can rotate around the direction of its central axis.

[0034] In the embodiment of the present application, a communicating air passage is formed by forming the first air inlet 113 on the circuit board 111, the second air inlet 122 on the side wall of the bracket 120 and the third air inlet 132 on the side wall of the base 130, and a first sliding portion 123 is provided on the outer wall of the bracket 120, and a second sliding portion 133 cooperating with the first sliding portion 123 is provided on the inner wall of the base 130, so that the base 130 and the bracket 120 can rotate relative to each other. When the base 130 is rotated, the relative area between the second air inlet 122 and the third air inlet 132 will change. When the second air inlet 122 and the third air inlet 132 are completely overlapped, the opening area of ​​the air passage is the largest and the air intake effect is the best. As the base 130 rotates, the overlapping area of ​​the second air inlet 122 and the third air inlet 132 gradually decreases, and the opening area of ​​the air passage gradually decreases, so that the air intake effect gradually decreases. Through this setting, the air intake volume of the product will also change when it is in use, achieving the effect of adjusting the air and realizing the switching of the air intake gears, providing users with more inhalation modes, thereby meeting the usage needs of different users and improving the user experience.

[0035] In addition, the bottom air-adjusting structure 100 further includes a sealing silicone 140, which is disposed in the bracket 120 and sleeved on the USB socket 112 to protect the USB socket 112 and prevent the USB socket 112 from being damaged by collision during assembly. Moreover, the sealing silicone 140 has a step surface, which faces the first air inlet 113 to prevent the sealing silicone 140 from affecting the air intake effect.

[0036] In the application embodiment, the inner wall of the bracket 120 is provided with a support seat 126, and the side of the circuit board 111 facing the USB port 112 abuts against the support seat 126; a screw hole 127 is provided in the support seat 126, and the opening of the screw hole 127 faces the circuit board 111, and a through hole 114 corresponding to the screw hole 127 is provided on the circuit board 111, and the screw hole 127 and the through hole 114 are connected by a screw 150 to fix the circuit board 111 on the support seat 126. There are two support seats 126, which are respectively located on opposite sides of the bracket 120 to support the two ends of the circuit board 111.

[0037] During the product assembly process, the sealing silicone 140 is first installed in the bracket 120, and then the USB plug board 110 is installed in the bracket 120, and the USB socket 112 is inserted into the sealing silicone 140, and then the USB plug board 110 is fixed to the bracket 120 with screws 150, and then the base 130 is installed on the bracket 120 through the snap-on structure, and finally the shell 300 is installed on the bracket 120 and connected to the upper part of the bracket 120.

[0038] Combination Figure 4 , Figure 5 and Figure 6 As shown, in the embodiment of the present application, the first sliding portion 123 is a sliding groove 128, and the sliding groove 128 is an annular concave structure extending around the central axis of the bracket 120; the second sliding portion 133 is a sliding boss 136, and the sliding boss 136 is an annular convex structure extending around the central axis of the base 130, and the sliding boss 136 is slidably connected with the sliding groove 128. Through this arrangement, the sliding groove 128 and the sliding boss 136 are engaged, so that the base 130 and the bracket 120 form a continuous contact point, and the base 130 has good stability when rotating.

[0039] Of course, the first sliding portion 123 may be two or more sliding grooves 128, and the two or more sliding grooves 128 are sequentially distributed in the height direction of the electronic atomization device 10, and correspondingly, the second sliding portion 133 may be two or more sliding bosses 136. The first sliding portion 123 and the second sliding portion 133 may also be a ring structure connected at the end, or a half-circle, a quarter-circle arc structure, etc.

[0040] In other embodiments, the first sliding portion 123 may be a sliding boss 136 , and the second sliding portion 133 may be a sliding groove 128 .

[0041] In the application embodiment, the outer wall of the bracket 120 is further provided with a limiting protrusion 124, and the limiting protrusion 124 extends in the direction of the central axis of the bracket 120; correspondingly, the inner wall of the base 130 is provided with a limiting groove 134, and the limiting groove 134 extends in the direction of the central axis of the base 130. When the base 130 and the bracket 120 are assembled, the limiting protrusion 124 is inserted into the corresponding limiting groove 134, and the limiting groove 134 and the limiting protrusion 124 are plugged and matched.

[0042] The extending length of the limiting groove 134 is greater than the extending length of the limiting protrusion 124 , and when the base 130 is rotated, the limiting protrusion 124 can rotate in the limiting groove 134 .

[0043] Specifically, the extension length of the limiting groove 134 is less than half a circle, and the rotation angle of the base 130 and the limiting protrusion 124 is less than 180 degrees, and can further be less than 60 degrees.

[0044] Of course, the number of the limiting protrusions 124 and the limiting grooves 134 may be not one, but two or more, and the selection is made according to the actual situation.

[0045] In other embodiments, the limiting protrusion 124 may be disposed on the inner wall of the base 130 , and the limiting groove 134 may be correspondingly disposed on the outer wall of the bracket 120 .

[0046] like Figure 7 As shown, in another embodiment, the first sliding portion 123 also includes at least one first clamping portion 125, and the first clamping portion 125 is arranged on the outer side of the bracket 120, and the second sliding portion 133 also includes at least one second clamping portion 135, and the second clamping portion 135 is arranged on the inner side of the base 130, and the first clamping portion 125 and the second clamping portion 135 are snap-fitted to further improve the connection strength and stability between the base 130 and the bracket 120.

[0047] The first clamping portion 125 is a notch, and the second clamping portion 135 is a hook, and the notch and the hook engage with each other; the notch extends in the direction of the central axis around the bracket 120, and the hook extends in the direction of the central axis around the base 130, and the extension length of the notch is greater than the extension length of the hook, so that the base 130 can rotate, and the connection effect between the base 130 and the bracket 120 is not affected during the rotation of the base 130.

[0048] In other embodiments, the first engaging portion 125 may be a hook, and the second engaging portion 135 may be a notch.

[0049] In the application embodiment, the sliding groove 128 is located between the first clamping portion 125 and the limiting protrusion 124, and the sliding boss 136 is located between the second clamping portion 135 and the limiting groove 134. When the bracket 120 and the base 130 are assembled, the parts located in the middle and the top of the bracket 120 are connected and fixed, which not only performs rotational cooperation and rotational limitation, but also improves the connection stability between the base 130 and the bracket 120.

[0050] In addition, combined Figure 4 , Figure 5 and Figure 6 As shown, along the direction away from the atomizer 200, that is, from the circuit board 111 to the USB port 112, the width of the base 130 and the width of the bracket 120 gradually decrease, so that when the bottom of the bracket 120 is inserted from the top of the base 130, the assembly between the first sliding part 123 and the second sliding part 133, the assembly between the first clamping part 125 and the second clamping part 135, and the assembly between the limiting groove 134 and the limiting protrusion 124 are more convenient.

[0051] The above contents are further explanations of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these explanations. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
