The second elastic sealing sheet 28 is mounted on the side of the fixed base 20 and elastically abuts against the air regulating member 29, which is used to seal the opening of the first end of the air guide hole 202 and prevent the air regulating member 29 from sliding freely, thereby improving the stability of the air intake.

[0034] One end of the liquid storage assembly 3 is inserted into the docking slot 200, and the other end is located outside the housing 1. The liquid storage assembly 3 includes a liquid storage tube 31, a vent tube 32, a sealed base 33, a bottom cover 34, a liquid-absorbing cotton pad 35, a second electrode 36, and a second magnet 37. The vent tube 32 is located within the liquid storage tube 31, with one end of the vent tube 32 connected to the liquid storage tube 31 and the other end of the vent tube 32 connected to the sealed base 33. A liquid storage cavity for storing the aerosol-generating substrate is formed between the vent tube 32 and the liquid storage tube 31. The side wall of the vent tube 32 is provided with a liquid guide hole 321, which communicates with the liquid storage cavity.

[0035] The sealing base 33 is located inside one end of the liquid storage tube 31 and covers the opening of the liquid storage cavity. The bottom cover 34 is located at the end face of the liquid storage tube 31 and is connected to the liquid storage tube 31 and the sealing base 33. The liquid-absorbing cotton sheet 35 is located inside the bottom cover 34 and is used to absorb leaked aerosol-generating matrix.

The second magnet 37 is fixed to the bottom cover 34 and is magnetically connected to the first magnet 25.

[0036] The atomizer core 4 is located within the liquid storage assembly 3 and is electrically connected to the control board 22. The atomizer core 4 is in communication with the first sensing air hole 201. Specifically, the atomizer core 4 includes a porous liquid pipette 41, an electric heating element 42, a fixed tube 43, and a sealing tube 44. The porous liquid pipette 41 is located within the fixed tube 43 and is used to adsorb the aerosol-generating matrix. The porous liquid pipette 41 can be a porous ceramic tube or a fiber tube formed by winding fiber cloth, etc., as long as it can adsorb the aerosol-generating matrix, and its material is not specifically limited here. The electric heating element 42 is attached to the porous liquid pipette 41 and is electrically connected to the second electrode 36 to atomize the aerosol-generating matrix. The electric heating element 42 can be an electric heating grid or an electric heating wire, etc., as long as it can atomize the aerosol-generating matrix. The fixed tube 43 is sleeved on the outside of the porous liquid pipette 41, and the sealing tube 44 is sleeved on the outside of the fixed tube 43. The sealing tube 44 can be formed by winding non-woven fabric or cotton fabric.

[0037] The display screen 5 is connected to the control board 22 and extends into the first receiving slot 12. The display screen 5 is used to display information about the electronic cigarette, such as the battery level and the remaining amount of aerosol-generating substrate. The light-transmitting cover 6 is provided with a second receiving slot 61, a first positioning hole 62, a first limiting protrusion 63, a second limiting protrusion 64, and a second positioning post 65. The light-transmitting cover 6 covers the display screen 5 and is connected to the housing 1 and the control board 22. The display screen 5 extends into the second receiving slot 61. Therefore, the light-transmitting cover 6 assists in positioning the display screen 5, ensuring more accurate positioning.

[0038] The first positioning post 13 is plugged into the first positioning hole 62, facilitating the installation of the display screen 5 in the desired position during assembly. The first limiting protrusion 63 is located on the side of the light shield 6 facing the control board 22. This abuts the control board 22, preventing the light shield 6 from shifting due to external forces. The second positioning post 65 is plugged into the second positioning hole 221, providing a more stable and reliable structure.

[0039] The first cover 7 is provided with a display window 71, a limiting groove 72, and a third receiving groove 73. The first cover 7 is provided on the first side of the housing 1. The display window 71 corresponds to the position of the display screen 5 and the light-transmitting cover 6. The user can observe the information on the display screen 5 through the display window 71. The second limiting protrusion 64 is inserted into the limiting groove 72. Preferably, the second limiting protrusion 64 is located at the edge of the light-transmitting cover 6, and the first positioning hole 62 is located at the second limiting protrusion 64. The light-transmitting cover 6 extends into the third receiving groove 73 to ensure that the light-transmitting cover 6 and the first cover 7 are tightly combined. The second cover 8 is located on the second side of the housing 1, and the first cover 7 and the second cover 8 are arranged in opposite positions. The first cover 7 and the second cover 8 are both connected to the housing 1 by snapping, so there is no need to fix the first cover 7 and the second cover 8 with screws, etc., which is more convenient for assembly.

[0040] Because the first end of the elastic sealing seat 23 elastically abuts the fixing seat 20, and the second end of the elastic sealing seat 23 elastically abuts the control board 22, the second sensing hole 231 communicates with the first sensing hole 201. The airflow sensor 24 is connected to the control board 22 and communicates with the first sensing hole 201 through the second sensing hole 231. As a result, the airflow path between the airflow sensor 24 and the docking slot 200 is well sealed, improving the sensitivity of the airflow sensor 24 and preventing the user from inhaling excessive air. Furthermore, its compact and reliable structure takes up little space, facilitating product miniaturization.

[0041] In summary, the present invention utilizes the coordination between the housing 1, control panel 22, display screen 5, light-transmitting cover 6, and first cover 7. The housing 1 is provided with a first receiving slot 12 on its outer side, the control panel 22 is connected to the housing 1, the display screen 5 is connected to the control panel 22 and extends into the first receiving slot 12, and the light-transmitting cover 6 covers the display screen 5 and is connected to the housing 1 and control panel 22. This allows the display screen 5 to be positioned within the space formed by the housing 1 and light-transmitting cover 6. This facilitates assembly, and the display screen 5 and light-transmitting cover 6 are easily aligned, resulting in a more reliable structure.
