[0044] In one embodiment, referring to Figures 1-6 , the power supply assembly of the atomization device includes a shell 100, a battery compartment 200, a control button 300, and a switch part 400.

[0045] Please refer to Figure 1 and Figure 2 The shell 100 can be understood as the main structural part constituting the outer contour of the power supply assembly and the atomization device. The shell 100 has a mounting cavity 110, which can be used to mount part or all of the elements of the power supply assembly except the shell 100, or can be used to provide mounting space for other components such as the atomizer 900 in the atomization device.

[0046] Exemplarily, the shell 100 can include a barrel with two open ends, the inner cavity of the barrel forms the mounting cavity 110, and the opening at one end of the barrel can be provided with a cover 120.

[0048] In an embodiment, referring to Figures 1-3 The battery compartment 200 is arranged in the mounting cavity 110, and the battery compartment 200 includes a main body part 210 and a pressable part 220 arranged integrally. The pressable part 220 includes a pressing part 221 and an elastic arm 222. The pressing part 221 is connected to the main body part 210 through the elastic arm 222. The elastic arm 222 is used to provide an elastic force to the pressing part 221 after the displacement of the pressing part 221, so as to drive the pressing part 221 to reset.

[0049] The shell 100 is provided with a button hole 130. The button hole 130 is arranged at a position corresponding to the pressing part 221. The control button 300 is movably arranged in the button hole 130, and is used to transmit a pressing force to the pressing part 221. The switch piece 400 is arranged on a side of the pressing part 221 away from the button hole 130. The pressing control button 300 can drive the displacement of the pressing part 221, so as to trigger the switch piece 400.

[0050] In use, a pressure is applied to the control button 300 from the outside of the shell 100. The control button 300 transmits the pressure to the pressing part 221, so that the pressing part 221 is driven to displace towards the switch piece 400, thereby triggering the switch piece 400.

[0051] By arranging the pressable part 220 on the battery compartment 200, the elastic force provided by the elastic arm 222 helps to enhance the pressing feeling of the control button 300, and also helps to reduce the risk of accidental triggering of the control button 300. Since the pressable part 220 is integrated on the battery compartment 200, the pressable part 220 can be integrally processed and formed with the battery compartment 200, which facilitates production and assembly, and helps to avoid increasing the assembly difficulty of the power supply assembly due to the arrangement of the pressable part 220.

The button hole 130 corresponding to the pressable part 220 is arranged on a side of the shell 100, so that the control button 300 can be pressed from the side surface of the shell 100. This facilitates pressing the control button 300 at any time when holding the power supply assembly, and facilitates use.

[0053] Those skilled in the art can understand that the battery compartment 200 can be made of metal, plastic or other elastic materials, so that the elastic arm 222 can generate elastic force after deformation. In other embodiments, only the elastic arm 222 or the pressable part 220 can be made of elastic material.

[0054] In an embodiment, referring to Figure 3 and Figure 4 The elastic arm 222 can have at least one bending section 2221 to extend the length of the elastic arm 222 in the case of limited installation space, and to maximize the elastic feedback strength of the elastic arm 222 after being pressed, which helps to further improve the key feel.

[0055] In order to improve the structural stability of the pressable part 220 and reduce the risk of damage caused by pressing, in an embodiment, the opposite sides of the pressing part 221 can be connected with one elastic arm 222.

[0056] In some embodiments, the two elastic arms 222 can be arranged in a symmetrical or central symmetrical manner on the two sides of the pressing part 221; for example, the pressing part 221 can be square, and the two elastic arms 222 are connected at two opposite corners of the pressing part 221. The bending sections 2221 corresponding to the two elastic arms 222 are opposite to each other, so that the two elastic arms 222 are arranged in a central symmetrical or approximately symmetrical manner with respect to the center of the pressing part 221. In order to share the pressure when being pressed, which helps to improve the structural strength.

[0057] Exemplarily, the elastic arm 222 can include a first section 2222, a second section 2223 and a third section 2224 connected in sequence, the first section 2222 is connected with the pressing part 221, the third section 2224 is connected with the main body part 210, the first section 2222 and the third section 2224 are arranged in parallel, and the second section 2223 is perpendicular to the first section 2222 and the third section 2224, so that the connection between the second section 2223 and the first section 2222 and the connection between the second section 2223 and the third section 2224 form the bending section 2221.

[0058] The pressing part 221 has a first side surface 2211 and a second side surface 2212 each connected with an elastic arm 222, the main body part 210 has a first connecting surface 211 opposite to the first side surface 2211 and a second connecting surface 212 opposite to the second side surface 2212, the third section 2224 of one elastic arm 222 is connected to the part of the first connecting surface 211 opposite to the first side surface 2211, and the third section 2224 of the other elastic arm 222 is connected to the part of the second connecting surface 212 opposite to the second side surface 2212.

[0059] Those skilled in the art can understand that the shape of the elastic arm 222 and the number and position of the elastic arm 222 are not limited, as long as they can meet the design and use requirements.

[0060] In an embodiment, referring to Figure 2 and Figure 5 The control button 300 can include a button cap 310 and a buffer pad 320. The button cap 310 is movably clamped in the button hole 130, and the buffer pad 320 is clamped between the button cap 310 and the pressing portion 221. The buffer pad 320 has elasticity, and is used to provide the button cap 310 with elastic force in a direction away from the pressing portion 221. By arranging the buffer pad 320, pressing feedback can be immediately generated when the pressing is started. By cooperating with the pressable portion 220, continuous pressing feedback can be generated during the pressing, which helps to further improve the button feel.

[0061] In an embodiment, the button cap 310 includes a cap body 311 and two clamping elastic arms 312. The cap body 311 can have a mounting groove 3111 opening towards the pressing portion 221. The buffer pad 320 can be partially mounted in the mounting groove 3111, and the remaining part protrudes out of the mounting groove 3111 to abut against the pressing portion 221.

[0062] The two clamping elastic arms 312 protrude from the cap body 311 at one end close to the pressing portion 221, and are oppositely arranged on opposite sides of the cap body 311. The side of the two clamping elastic arms 312 away from each other has a clamping protrusion 3121, which is used to abut against the cavity wall of the mounting cavity 110 to limit the button cap 310 from being pulled out of the button hole 130.

[0063] In order to facilitate the button cap 310 to be assembled into the button hole 130 from the outside of the shell 100, in an embodiment, the clamping protrusion 3121 is located on the side of the clamping elastic arm 312 close to the cap body 311, so that the side of the clamping elastic arm 312 away from the cap body 311 forms a guide section 3122. When the button cap 310 is assembled, the guide section 3122 can be inserted into the button hole 130 before the clamping protrusion 3121, so as to guide the insertion of the part provided with the clamping protrusion 3121, which helps to reduce the assembly difficulty of the button cap 310.

[0064] The elastic arm 222 is arranged in a staggered manner with the guide section 3122 to avoid the movement of the guide section 3122. For example, the first section 2222 and the second section 2223 of the elastic arm 222 form an avoidance area with the pressing portion 221. The guide section 3122 can move in the avoidance area to avoid the interference of the elastic arm 222 to the pressing of the control button 300.

[0065] In order to make the different parts of the control button 300, such as the edge and the middle part, have the same or substantially same pressing feeling when the control button 300 is pressed, in an embodiment, the pressing part 221 has a supporting area towards the surface of the control button 300, and the control button 300 has a pressing surface 321 towards the pressing part 221, and the contact position of the pressing surface 321 and the pressing part 221 is located in the supporting area. Thus, no matter the edge or the middle part of the control button 300 is pressed, the pressing surface 321 can fully contact with the pressing part 221, so that the same or substantially same feeling feedback is obtained.

[0066] For example, the cushion 320 has a plane as the pressing surface 321 towards one side of the pressing part 221, and the pressing part 221 is arranged opposite to the cushion, and the pressing part 221 also has a plane towards the side of the pressing surface 321, the middle part of the plane forms a supporting area opposite to the pressing surface 321, and the area of the supporting area should be not less than the area of the pressing surface 321, so that the contact position of the pressing surface 321 and the pressing part 221 is located in the supporting area.
