[0035] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0036] Please refer to Figures 1 to 4 , in some embodiments, an aerosol - generating device is provided, which includes an atomization unit 1, a control unit 2, a first housing 31, and a receiving seat 4.

[0037] The atomization unit 1 is used to store and heat the aerosol - generating matrix. The aerosol - generating matrix can be a liquid or solid aerosol - generating matrix. The liquid aerosol - generating matrix includes e - liquid, medicinal liquid, etc. The atomization unit 1 can heat the aerosol - generating matrix when powered on to generate an aerosol for the user to inhale.

[0038] The control unit 2 includes a circuit board 21, a switch 22, a light-emitting element 23, and a light-transmitting button 24. The circuit board 21 has a control circuit that can control the power-on and power-off of the atomization unit 1 through an electrical signal, thereby controlling the heating of the atomization unit 1. The switch 22 is an electronic component that can open the circuit, interrupt the current, or cause it to flow to other circuits. This switch 22 can be used to control the power, mode, etc. of the atomization unit 1. For example, the switch 22 can be a tactile switch provided on the circuit board 21, etc. The light-emitting element 23 can be a component with light-emitting performance such as an LED, and can emit light in the powered-on state. The on-off of the light-emitting element 23 can be controlled by the control circuit on the circuit board 21. Thus, various status information of the aerosol generating device (such as the on state and off state, power information, etc.) can be indicated to the user through the brightness information. The light-transmitting button 24 can be made of light-guiding silica gel.

[0039] A power supply unit is provided inside the first housing 31. The power supply unit includes a power source 32 provided inside the first housing 31. The power source 32 is used to connect to the circuit board 21 of the control unit 2 to supply power to the control unit 2 and the atomization unit 1.

[0040] The atomization unit 1 is partially received in the receiving seat 4. The receiving seat 4 and the circuit board 21 are received inside the first housing 31. Specifically, the atomization unit 1 and the receiving seat 4 can be detachably connected together, and the circuit board 21 and the receiving seat 4 can also be detachably connected together. The receiving seat 4 can be detachably (directly or indirectly) connected to the first housing 31, so that the receiving seat 4 is separably provided inside the first housing 31. After the atomization unit 1, the circuit board 21, and the receiving seat 4 are assembled as a whole, the atomization unit 1, the circuit board 21, and the receiving seat 4 can be transported as a whole and assembled with the power supply unit as a whole. Thus, there is no need to additionally design a positioning structure for the control unit 2, saving components and facilitating assembly. The structure is compact and suitable for small spaces. During assembly, the atomization unit 1, the circuit board 21, and the receiving seat 4 are placed as a whole inside the first housing 31, and the power source 32 of the power supply unit is connected to the control unit 2. In some embodiments, when the atomization unit 1 needs to be replaced, the receiving seat 4 can be taken out from the inside of the first housing 31, and the circuit board 21 remains inside the first housing 31.

[0041] The switch 22 and the light-emitting element 23 are respectively arranged on the circuit board 21, and the light-transmitting button 24 is located on one side of the switch 22 and can be in contact with the switch 22. Specifically, the light-transmitting button 24 can be located on one side of both the switch 22 and the light-emitting element 23, or can be only located on one side of the switch 22. There may or may not be a connection relationship between the light-transmitting button 24 and the circuit board 21. The first housing 31 is provided with a mounting hole 310, and the mounting hole 310 is located at the lower part of the receiving seat 4. The light-transmitting button 24 is adapted to the mounting hole 310, that is, at least part of the outer shape of the light-transmitting button 24 is adapted to the inner diameter of the mounting hole 310. The receiving seat 4 is provided with a first notch 410, and the first notch 410 is located on the lateral side of the circuit board 21. This lateral direction can be perpendicular to the length direction of the aerosol generating device. Therefore, the first notch 410 is also located on the lateral side of the switch 22 and the light-emitting element 23 on the circuit board 21. The light-transmitting button 24 enters the inside of the first housing 31 through the mounting hole 310 and at least partially extends to the first notch 410. Thus, through the avoidance design of the first notch 410, the light-transmitting button 24 can also be located on the lateral side of the switch 22 and the light-emitting element 23 on the circuit board 21. The part of the light-transmitting button 24 located inside the first housing 31 is arranged on one side of the switch 22 and can be in contact with the switch 22.

[0042] When the atomizing unit 1, the circuit board 21 and the receiving seat 4 are assembled with the first housing 31 as a whole, the light-transmitting button 24 located below the receiving seat 4 is just arranged in the mounting hole 310 so as to be at least partially exposed outside the mounting hole 310. For example, a part of the light-transmitting button 24 enters the inside of the first housing 31 and extends to the first notch 410, and the other part is exposed outside the mounting hole 310. For example, part of the light-transmitting button 24 protrudes from the outer surface of the first housing 31 where the mounting hole 310 is located for the user to press; or, the middle part of the light-transmitting button 24 is recessed and exposed outside the mounting hole 310 to adapt to the pressing curve of the finger. That the light-transmitting button 24 can be in contact with the switch 22 means that when needed, the light-transmitting button 24 has the ability to be in contact with the switch 22, but the light-transmitting button 24 does not necessarily be in contact with the switch 22 all the time and can also be in a separated state from the switch 22.

[0043] According to the above settings, in the first aspect, the light-transmitting button 24 is located on one side of the switch 22 and can contact the switch 22 to serve as a trigger for the switch 22. The mode and power of the aerosol generating device and other status information can be changed by triggering the switch 22. In the second aspect, the light-transmitting button 24 has the ability to transmit light and can transmit the light generated by the light-emitting element 23. Through the mounting hole 310 on the first housing 31, the light-transmitting button 24 can transmit the light generated by the light-emitting element 23 to the outside of the first housing 31, enabling the user to perceive the brightness information, which instantaneously feedbacks the current status information of the aerosol generating device and improves the user experience. In the third aspect, since the first notch 410 is located on the lateral side of the circuit board 21, the first notch 410 is also located on the lateral side of the switch 22 and the light-emitting element 23 on the circuit board 21. And the light-transmitting button 24 is at least partially located in the mounting hole 310, can enter the inside of the first housing 31 through the mounting hole 310, and at least partially extends to the first notch 410 and contacts the switch 22. The user can press the light-transmitting button 24 from the outside to operate the switch 22 for control. Through the avoidance design of the first notch 410, the light-transmitting button 24 can also be located on the lateral side of the switch 22 and the light-emitting element 23 on the circuit board 21, thereby serving as a trigger for the switch and not affecting the disassembly and assembly of the receiving seat 4. Thus, the light-transmitting button 24, the receiving seat 4, and the circuit board 21 cooperate closely with each other without interference, enhancing the structural compactness of the aerosol generating device. In addition, when the atomization unit 1, the circuit board 21, and the receiving seat 4 are assembled with the first housing 31 as a whole, the assembly direction and assembly position can be determined through the matching relationship between the light-transmitting button 24 and the mounting hole 310, which has the function of preventing reverse installation.

[0044] Such as Figure 4 And Figure 5As shown, in some embodiments, the atomization unit 1 includes a second housing 12 and an atomization core 11. The second housing 12 is sleeved around the periphery of the atomization core 11. The second housing 12 is sleeved on the outer periphery of the receiving seat 4. The receiving seat 4 defines a receiving cavity 420, and a part of the atomization core 11 is received in the receiving cavity 420. Specifically, the atomization unit 1 further includes a seal 13, and the seal 13 is sleeved on the outer periphery of the atomization core 11. The second housing 12 is sleeved on the outer periphery of the seal 13. The atomization core 11 is connected to the second housing 12. The second housing 12, the seal 13 and the atomization core 11 together define a liquid storage cavity 14. The liquid storage cavity 14 is used for storing the aerosol generating matrix. Further, the atomization core 11 may include a hollow atomization tube 110, a hollow liquid guiding member 111 disposed on the inner periphery of the atomization tube 110, a heating body 112 attached to the inner periphery of the liquid guiding member 111, and two heating wires 113 connected to the heating body 112. The heating wires 113 are connected to the control unit 2. Among them, the second housing 12 is detachably connected to the first housing 31, so that the atomization unit 1, the circuit board 21 and the receiving seat 4 are assembled with the first housing 31 as a whole.

[0045] As Figure 7 and Figure 8 shown, in some embodiments, a second notch 412 is provided at the position of the circuit board 21 facing the mounting hole 310. The second notch 412 is correspondingly provided with the first notch 410, and the light-transmitting button 24 extends at least partially into the space defined by the first notch 410 and the second notch 412. Thus, through the avoidance design of the second notch 412, the light-transmitting button 24 and the circuit board 21 are closely matched with each other and do not interfere with each other, further improving the structural compactness of the aerosol generating device.

[0046] As Figures 5 to 8 shown, in some embodiments, the switch 22 is disposed on one side of the second notch and is disposed from one side of the circuit board 21 towards the direction of the light-transmitting button 24. Specifically, the switch 22 and the light-emitting element 23 may be respectively located on both sides of the circuit board 21 in the up-down direction. In other embodiments, the relative positions of the switch 22 and the light-emitting element 23 on the circuit board 21 can also be freely adjusted.

[0047] As Figure 4 shown, in some embodiments, a third notch 413 is recessed on the surface of the receiving seat facing the circuit board 21. The third notch 413 is adjacent to the first notch 410, and the light-emitting element 23 can partially extend to the third notch 413.

[0048] As Figures 5 to 8As shown, in some embodiments, the receiving base 4 is provided with a plurality of limiting portions spaced circumferentially, and the circuit board 21 is limited on the receiving base 4 through these limiting portions. Further, the receiving base 4 includes a side wall 42 and a bottom wall 43 that are joined. The side wall 42 is generally cylindrical, and the side wall 42 and the bottom wall 43 together define a receiving cavity 420. At least a part of the atomizing unit 1 is received in the receiving cavity 420. Specifically, at least a part of the atomizing core 11 is received in the receiving cavity 420. For example, in some embodiments, the bottom end of the atomizing tube 110 is disposed in the receiving cavity 420. The sealing member 13 includes a first portion 131 and a second portion 132. The first portion 131, together with the second housing 12 and the atomizing core 11, defines a liquid storage cavity 14. The outer periphery of the second portion 132 is hermetically joined to the inner periphery of the side wall 42. Therefore, the second portion 132 of the sealing member 13 is also received in the receiving cavity 420.

[0049] The circuit board 21 is horizontally disposed at the lower part of the receiving base 4. For example, the circuit board 21 abuts against the bottom of the bottom wall 43. The limiting portions include a first limiting portion 41 and a second limiting portion 44 provided on the bottom wall 43. The first limiting portion 41 forms a first notch 410. The second limiting portion 44 is located on one side of the first limiting portion 41. The circuit board 21 is clamped between the first limiting portion 41 and the second limiting portion 44, thereby realizing the positioning between the circuit board 21 and the receiving base 4. Both the first limiting portion 41 and the second limiting portion 44 can be clamping claws. Specifically, the switch 22 and / or the light-emitting element 23 are exposed at the first notch 410. That is, it can be that only the switch 22 is exposed at the first notch 410, or only the light-emitting element 23 is exposed at the first notch 410, or both the switch 22 and the light-emitting element 23 are exposed at the first notch 410. Specifically, as Figures 5 to 8 shown, the above-mentioned plurality of limiting portions include two clamping claws 411 spaced circumferentially along the bottom wall 43, and the interval between the two clamping claws 411 forms the first notch 410. In some other embodiments, the first limiting portion 41 can also be provided on the side wall 42.

[0050] Further, as Figures 5 to 8 shown, in some embodiments, both the first limiting portion 41 and the second limiting portion 44 are provided with bosses 45 extending radially. The edge of the circuit board 21 abuts against the bosses 45 to be limited. According to the above arrangement, the first limiting portion 41 on the bottom wall 43 can not only avoid the position for the light-transmitting button 24 through the first notch 410, but also cooperate with the second limiting portion 44 to position the circuit board 21, forming a compact and reasonable limiting structure, which is beneficial to saving many limiting components, facilitating assembly, and being applicable to small spaces.

[0051] Specifically, when the atomizing unit 1, the circuit board 21 and the receiving base 4 are assembled into the first housing 31 as a whole, the bottom wall 43 just faces the top surface of the power supply 32.

[0052] As shown in FIGS. 4 and Figure 9 shown, in some embodiments, the surface of the light-transmitting button 24 facing the switch 22 is provided with a groove 240 for accommodating the switch 22. After the atomization unit 1, the circuit board 21, and the receiving seat 4 are assembled as a whole into the first housing 31, the switch 22 is received in the groove 240. Thus, the switch 22 and the light-transmitting button 24 are closely fitted, and the user can touch the switch 22 by gently touching the light-transmitting button 24 on the outside of the first housing 31, so as to realize operations such as mode adjustment and power adjustment of the aerosol generating device.

[0053] As shown in FIGS. 4 and Figure 9 shown, in some embodiments, the light-transmitting button 24 is provided with an inclined surface 241 on the side facing the switch 22. As shown in FIGS. 4 and Figure 9 shown in the embodiments, the side of the light-transmitting button 24 facing the switch 22 is referred to as the inner side, and the side of the light-transmitting button 24 facing away from the switch 22 element is referred to as the outer side. When the user presses the light-transmitting button 24 on the outer side, the switch 22 can be touched. A circle of inclined surfaces 241 is provided on the inner side of the light-transmitting button 24, so that the inner side of the light-transmitting button 24 forms a cone. The positions of these inclined surfaces 241 can function to avoid interference, for example, to avoid interfering with the receiving seat 4 above and the power supply 32 below.

[0054] In order to prevent the light-transmitting button 24 from disengaging from the mounting hole 310 of the first housing 31 when the receiving seat 4 is disassembled and assembled, in some embodiments, the size of the portion of the light-transmitting button 24 located inside the first housing 31 can be larger than the size of the mounting hole 310. Specifically, the cross-sectional area of the portion of the light-transmitting button 24 located inside the first housing 31 along the length direction of the aerosol generating device can be larger than the area of the mounting hole 310.

[0055] As Figures 5 to 8 shown, in some embodiments, the circuit board 21 includes a first surface 211 facing the bottom wall 43 of the receiving seat 4 and a second surface 212 facing away from the bottom wall 43 of the receiving seat 4. The switch 22 is disposed on the second surface 212, and the light-emitting element 23 is disposed on the first surface 211. Thus, as Figures 5 to 7 shown, the switch 22 and the light-emitting element 23 can be simultaneously disposed at the edge positions of the circuit board 21, respectively located on the upper and lower sides of the circuit board 21, which is beneficial to simultaneously disposing the light-transmitting button 24 on one side of the switch 22 and one side of the light-emitting element 23. The projections of the switch 22 and the light-emitting element 23 in the direction facing the light-transmitting button 24 are both within the range of the light-transmitting button 24, that is, the light-transmitting button 24 at least covers the projections of the switch 22 and the light-emitting element 23 in the direction facing the light-transmitting button 24.

[0056] As Figures 5 to 8As shown, in some embodiments, the control unit 2 further includes two electrode posts 25 disposed on the circuit board 21. The receiving seat 4 is provided with two first through holes 46. After the two electrode posts 25 respectively pass through the two first through holes 46, they are electrically connected to the atomization unit 1. Specifically, the two electrode posts 25 are respectively connected to the heating wire 113 after passing through the two first through holes 46. As Figure 8 As shown, in some embodiments, the bottom wall of the atomization tube 110 is provided with two second through holes 1102 and two blind holes 1101. One end of the two heating wires 113 away from the heating body 112 respectively passes through the two second through holes 1102 and is bent by a part. The bent parts are fixed at the two blind holes 1101. The two electrode posts 25 respectively pass through the two second through holes 1102 and abut against the two blind holes 1101, so that the two electrode posts 25 are respectively connected to the two heating wires 113.

[0057] As Figures 5 to 8 As shown, in some embodiments, the control unit 2 further includes two conductive connection parts 26 disposed on the circuit board 21. The two conductive connection parts 26 are respectively connected to the positive electrode and the negative electrode of the power supply 32. Specifically, the two conductive connection parts 26 are respectively connected to the positive electrode lead 321 and the negative electrode lead 322 of the power supply 32. During assembly, the atomization unit 1, the circuit board 21 and the receiving seat 4 are taken as a whole and placed inside the first housing 31, so that the positive electrode lead 321 and the negative electrode lead 322 of the power supply 32 are respectively connected to the two conductive connection parts 26. According to the above settings, a mechanical and / or electrical connection is established among the power supply 32, the two conductive connection parts 26, the circuit board 21, the two electrode posts 25, and the heating wire 113 of the atomization core 11.

[0058] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, based on the idea of the present invention, several simple deductions, deformations or replacements can also be made.
