[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific implementations.

[0028] See also Figures 1 to 8 The present invention provides an electronic atomization device, which includes a housing 1, a power supply assembly 2, a liquid storage assembly 3, an atomizing core 4, a display screen 5, a light-transmitting cover 6, a first cover 7, and a second cover 8. A receiving chamber 11 is provided at one end of the housing 1, and the receiving chamber 11 extends longitudinally along the housing 1. The housing 1 is also provided with an air inlet 11, a first receiving groove 12, and a first positioning post 13. The air inlet 11 is located on a first side of the housing 1, and the first receiving groove 12 and the first positioning post 13 are located on a second side of the housing 1. When a user inhales smoke, external air flows into the atomizing core 4 through the air inlet 11, and brings out smoke formed by atomizing liquid atomized by the atomizing core 4.

[0029] The power supply assembly 2 includes a fixing base 20, a first electrode 21, a control board 22, an elastic sealing base 23, and an airflow sensor 24. One end of the fixing base 20 is inserted into the accommodating cavity 11 and forms a docking groove 200 with the housing 1. The notch of the docking groove 200 is the cavity opening at one end of the accommodating cavity 11, and the docking groove 200 is used to accommodate the liquid storage assembly 3. The fixing base 20 is provided with a first air sensing hole 201, an air guide hole 202, and an air guide groove 203. One end of the first air sensing hole 201 is located at the groove wall of the docking groove 200 and is connected to the atomizer core 4 through the air guide groove 203. The first end of the air guide hole 202 is connected to the air inlet 11, and the second end of the air guide hole 202 is connected to the air guide groove 203. The air guide groove 203 is located at the groove wall of the docking groove 200, and the groove wall of the air guide groove 203 is provided with a limiting step 2031.

[0030] The first electrode 21 is fixed on the fixing base 20 and is electrically connected to the control board 22. The control board 22 is electrically connected to the atomizer core 4 through the first electrode 21. The control board 22 is provided with a second positioning hole 221, a third sensing air hole 222 and a control circuit for controlling the operation of the atomizer core 4. The control circuit is electrically connected to the first electrode 21. The first end of the control board 22 is connected to the fixing base 20, and the second end of the control board 22 is connected to the shell 1. The connection method is not specifically limited here. Since the first end of the control board 22 is connected to the fixing base 20 and the second end of the control board 22 is connected to the shell 1, the fixing base 20, the control board 22 and the shell 1 can be tightly connected together, thereby improving the reliability of the structure.

[0031] Furthermore, the control panel 22 is connected to a start switch 223, which is electrically connected to the control circuit. When a user begins using the electronic atomizer, they first press the start switch 223 a preset number of times within a preset time, thereby activating the electronic atomizer. This prevents the airflow sensor 24 from being accidentally triggered by changes in air pressure, thereby improving safety.

[0032] The elastic sealing seat 23 is located on the first side of the control panel 22 and is provided with a second sensing hole 231. The first end of the elastic sealing seat 23 elastically abuts the fixing seat 20, while the second end of the elastic sealing seat 23 elastically abuts the control panel 22. The second sensing hole 231 communicates with the first sensing hole 201, and the third sensing hole 222 corresponds to the position of the second sensing hole 231. The airflow sensor 24 is located on the second side of the control panel 22 and communicates with the second sensing hole 231 through the third sensing hole 222. The first and second sides of the control panel 22 are positioned opposite each other. The airflow sensor 24 is connected to the control panel 22 and communicates with the first sensing hole 201 through the third sensing hole 222 and the second sensing hole 231. This structure provides a good seal, increases the sensitivity of the airflow sensor 24, prevents the user from inhaling too much air, and improves the user experience.

[0033] The power supply assembly 2 of the present application further comprises a first magnet 25, a battery 26, a first elastic sealing sheet 27, a second elastic sealing sheet 28 and an air adjusting member 29. The first magnet 25 is fixed at the fixed seat 20, and the number of the first magnet 25 is two, which are arranged at intervals. The battery 26 is located in the space formed by the shell 1 and the control panel 22, and is electrically connected with the control panel 22, for supplying power to the atomizing core 4. The first elastic sealing sheet 27 covers part of the slot opening of the butt joint groove 200, and abuts against the limiting step 2031. The slot opening of the butt joint groove 200 is sealed by the first elastic sealing sheet 27, so that after the external gas enters the air inlet hole 11, it is transported to the area corresponding to the position of the atomizing core 4 by the butt joint groove 200, thus the gas leakage can be better avoided. The limiting step 2031 is used for limiting, thus the assembly is facilitated, and the consistency of the product is improved.

[0034] The air adjusting member 29 is movably arranged between the fixed seat 20 and the shell 1, for adjusting the air inlet amount of the air inlet hole 11 into the air guide groove 203. A plurality of air inlet amount adjusting holes 291 are arranged at the air adjusting member 29, the position of the air adjusting member 29 is adjusted up and down, so that one or more air inlet amount adjusting holes 291 are in communication with the air inlet hole 11 and the air guide hole 202, thereby adjusting the air inlet amount to meet the requirements of different users for different air inlet amounts. The second elastic sealing sheet 28 is installed at the side of the fixed seat 20 and elastically abuts against the air adjusting member 29, for sealing the hole opening of the first end of the air guide hole 202 and preventing the air adjusting member 29 from sliding arbitrarily, thereby improving the stability of the air inlet amount.

[0035] One end of the liquid storage assembly 3 is inserted into the butt joint groove 200, and the other end of the liquid storage assembly 3 is located outside the shell 1, which comprises a liquid storage tube 31, an air passage tube 32, a sealing base 33, a bottom cover 34, a liquid absorbing cotton sheet 35, a second electrode 36 and a second magnet 37. The air passage tube 32 is located in the liquid storage tube 31, one end of the air passage tube 32 is connected with the liquid storage tube 31, and the other end of the air passage tube 32 is connected with the sealing base 33. The air passage tube 32 and the liquid storage tube 31 form a liquid storage cavity for storing atomized liquid, and the side wall of the air passage tube 32 is provided with a liquid guide hole 321 in communication with the liquid storage cavity.

[0036] The sealing base 33 is located in one end of the liquid storage tube 31 and covers the cavity opening of the liquid storage cavity. The bottom cover 34 covers the end face of the liquid storage tube 31 and is connected with the liquid storage tube 31 and the sealing base 33. The liquid absorbing cotton sheet 35 is located in the bottom cover 34 and is used for absorbing the leaked atomized liquid. The second electrode 36 is fixed at the bottom cover 34 and is electrically connected with the atomizing core 4 and the first electrode 21. The second magnet 37 is fixed at the bottom cover 34 and is magnetically connected with the first magnet 25.

[0037] The atomizer core 4 is located in the liquid storage assembly 3 and is electrically connected to the control board 22. The atomizer core 4 is connected to 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 sealed tube 44. The porous liquid pipette 41 is located in the fixed tube 43 and is used to adsorb the atomized liquid. 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 atomized liquid, 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 for atomizing the atomized liquid. The electric heating element 42 can be an electric heating grid or an electric heating wire, etc., as long as it can atomize the atomized liquid. The fixed tube 43 is sleeved on the outside of the porous liquid pipette 41, and the sealed tube 44 is sleeved on the outside of the fixed tube 43. The sealed tube 44 can be formed by winding non-woven fabric or cotton cloth.

[0038] 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 atomizer liquid. 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.

[0039] 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.

[0040] 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.

[0041] In summary, since the fixing base 20 is provided with a first sensing air hole 201, one end of which is located on the wall of the docking slot 200, the first end of the control board 22 is connected to the fixing base 20, and the second end of the control board 22 is connected to the housing 1, the elastic sealing base 23 is provided with a second sensing air hole 231, the first end of the elastic sealing base 23 elastically abuts the fixing base 20, and the second end of the elastic sealing base 23 elastically abuts the control board 22, the second sensing air hole 231 is connected to the first sensing air hole 201, and the airflow sensor 24 is connected to the control board 22 and communicates with the first sensing air hole 201 through the second sensing air hole 231.
