[0028] Please refer to Figure 1-3 The utility model proposes an aerosol generator, comprising a shell 1, a cover 2, a display component 3 and at least one touch button 4. The display component 3 has an FPC (flexible circuit board) 31, and the display component 3 is installed on the shell 1 and exposed from the shell 1. The cover 2 covers the side of the shell 1 where the display component 3 is exposed. At least one touch button 4 includes a first end 401 and a second end 402, and the first end 401 is arranged on the cover 2, and the second end 402 is arranged on the FPC31. When the surface of the cover 2 corresponding to the first end 401 is touched, the second end is connected to the FPC, and the touch button 4 is triggered. The utility model sets the second end 402 of the touch button 4 on the FPC31 of the display component 3, so that the touch button 4 and the display component 3 share the same FPC31, and there is no need to set up a key control board separately, which not only saves a component, but also is conducive to the miniaturization design of the device due to the thin thickness of the FPC31, which is conducive to simplifying the structure and saving costs.

[0029] In some embodiments, Figure 1As shown, the housing 1 is provided with a first accommodating groove 11, and the first accommodating groove 11 is used to install components such as a battery assembly, a display assembly 3, a control assembly, and an atomization assembly. Among them, the battery assembly may include a battery element and a conductive element. The display assembly 3 includes a display screen, an FPC31 electrically connected to the display screen, and a support frame for supporting the display screen. The control assembly includes a main control board. The atomization assembly includes a housing, a heating element accommodated in the housing, an oil guide element, and an oil storage member. The main control board is electrically connected to the battery element through a conductive element, the FPC31 is connected to the main control board, and the heating element is electrically connected to the battery element. In this embodiment, the second end 402 of the touch button 4 is set on the FPC31, so that the touch button 4 is connected to the main control board via the FPC31, so that when the user triggers the touch button 4, the main control board controls the heating element to heat the oil and generate an aerosol according to the trigger signal.

[0030] In some embodiments, the display assembly 3 is arranged at the open end of the first receiving groove 11, so that the display screen can be exposed outside the housing 1 for viewing by the user. Correspondingly, the cover body 2 covers the housing 1 and closes the first receiving groove 11, so as to cover the components installed in the first receiving groove 11 in the housing 1 for protection. The cover body 2 includes an upper cover 22 and a lower cover 21. The lower cover 21 covers the side of the housing 1 where the display assembly 3 is installed and is fastened to the housing 1. In practical applications, the lower cover 21 can be connected to the housing 1 by a connection method such as a buckle 212 and a latch. The lower cover 21 is provided with a second receiving groove 211 adapted to the first receiving groove 11, and the opening of the second receiving groove 211 is opposite to the first receiving groove 11. When the lower cover 21 is installed on the housing 1, the second receiving groove 211 covers the first receiving groove 11, and the top wall of the second receiving groove 211 is opposite to the screen. Correspondingly, the top wall of the second receiving groove 211 is made of a translucent or fully transparent material, so that the screen can be exposed through the top wall of the second receiving groove 211 for viewing by the user.

[0031] In some embodiments, the upper cover 22 is provided with a third receiving groove 221 adapted to the lower cover 21. The opening direction of the third receiving groove 221 is the same as the opening direction of the second receiving groove 211. When the upper shell 1 is installed on the lower shell 1, the third receiving groove 221 covers the outer periphery of the lower cover 21, that is, the inner wall of the third receiving groove 221 fits with the outer periphery of the lower cover 21. Correspondingly, the top wall of the third receiving groove 221 fits with the top wall of the second receiving groove 211. In order to show the screen, the top wall of the third receiving groove 221 is made of semi-transparent or fully transparent material. It is worth noting that, except for the top wall of the receiving groove, other parts of the upper cover 22 and the lower cover 21 can be made of transparent material or opaque material, which is not limited here. In actual applications, at least one snap buckle 212 can be provided on the side wall of the second receiving groove 211, and at least one matching snap buckle 222 can be provided on the side wall of the third receiving groove 221. When the third receiving groove 221 covers the lower cover 21, the snap buckle 212 engages with the matching snap buckle 212, thereby fastening the upper cover 22 to the lower cover 21.

[0032] In some embodiments, Figure 1-3 As shown, the touch button 4 can be one, two or more, which includes a sensing sheet 43, a pad 41 and a conductive elastic member 42. The sensing sheet 43 is arranged on the top wall of the upper cover 22. Preferably, the sensing sheet 43 can be formed by a conductive ink layer printed on the top wall of the upper cover 22. In this way, the bonding between the sensing sheet 43 and the upper cover 22 is reliable and low in cost. The sensing sheet 43 can also be formed by a conductive cloth adhered to the top wall of the upper cover 22. Correspondingly, a touch area 223 corresponding to the sensing sheet 43 can be provided on the surface of the cover body 2 away from the shell 1. The touch area 223 is arranged just opposite to the sensing sheet 43, and its shape is the same as that of the sensing sheet 43, and its area can be less than or equal to the area of ​​the sensing sheet 43 to improve the sensing sensitivity. The touch area 223 can be identified by an indicating pattern. For example, the touch area 223 can be identified by a circle, a triangle and / or an arrow, or by other patterns. When a person touches the touch area 223, that is, the area where the identification pattern is located, the capacitance between the touch point and the sensor sheet 43 changes, and the capacitance change is transmitted to the second end 402 via the conductive elastic member 42. The second end 402 recognizes and responds to the touch button 4 by monitoring the capacitance change.

[0033] Please refer to Figure 1, the pad 41 is arranged on the FPC31. One end of the FPC31 is electrically connected to the display screen, and the other end is plugged into the main control board. The end of the FPC31 electrically connected to the display screen extends from the display screen and is parallel to the top walls of the second accommodating groove 211 and the third accommodating groove 221. By arranging the control pad 41 of the touch button 4 on the FPC31, the touch button 4 and the display component 3 share the same control board, which not only saves costs but also saves the internal space of the device. In practical applications, the shape of the pad 41 is set according to the shape of the conductive elastic member 42 to ensure that the contact area between the two is maximized, thereby ensuring the stability of conduction. For example, when the conductive elastic member 42 is annular, the pad 41 is annular; when the conductive elastic member 42 is square, the pad 41 can be a corresponding square structure, which is not listed here one by one.

[0034] like Figure 2 and Figure 3 As shown, the conductive elastic member 42 is located between the sensing sheet 43 and the pad 41, and one end thereof elastically abuts against the sensing sheet 43 to form the first end 401, and the other end thereof elastically abuts against the pad 41 to form the second end 402. In this embodiment, the conductive elastic member 42 is used as a conductive medium to conduct the sensing sheet 43 and the pad 41, and the elasticity of the conductive elastic member 42 is used to form a stable electrical connection, without the need for solder fixation, which makes installation simpler, and is conducive to improving assembly efficiency and quality, thereby improving touch sensitivity. In practical applications, the conductive elastic member 42 can be a conductive spring, which is pre-pressed between the upper cover 22 and the FPC 31, and one end of the conductive spring is elastically abutted against the sensing sheet 43, and the other end is elastically abutted against the pad 41, so as to conduct the sensing sheet 43 and the pad 41, and connect the first end 401 and the second end 402 of the touch button 4. In another embodiment, the conductive elastic member 42 may also be made of conductive silicone, and the elasticity of the silicone may be used to achieve stable electrical contact, and the transparency of the silicone may be set to guide light to the indicator light 44 disposed on the FPC 31. Of course, the conductive elastic member 42 may also be made of conductive springs.

[0035] In some embodiments, in order to ensure the stability of the position of the conductive elastic member 42, the lower cover 21 is provided with a guide hole 213 adapted to the conductive elastic member 42, and the central axis of the guide hole 213 passes through the center of the sensing sheet 43 and the touch area 223. In this way, when the conductive elastic member 42 is accommodated in the guide hole 213, the maximum sensing area can be guaranteed, thereby improving the sensitivity of the touch button 4. In this embodiment, the displacement of the conductive elastic member 42 is limited by the guide hole 213 to prevent the conductive elastic member 42 from being offset in a compressed state.

[0036] In some embodiments, the touch button 4 further includes an indicator light 44, which is disposed on the FPC 31, and the projection of the indicator light 44 on the upper cover 22 is located in the touch area 223. The projection may be at the center of the touch area 223, or may be offset from the center of the touch area 223. Preferably, the projection of the indicator light 44 on the upper cover 22 is located at the center of the touch area 223, so that the light emitted by the indicator light 44 can be emitted to the touch area 223 at the shortest distance, thereby ensuring the best light effect in the touch area 223, so that the indication pattern on the touch area 223 is illuminated, which is conducive to indicating the touch area 223. When the user touches the touch area 223 under the guidance of the indication pattern, the indicator light 44 emits light and the touch button 4 is triggered.

[0037] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
