If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0031] See also Figure 1 to Figure 3 , the electronic atomization device provided in this embodiment is now described. The electronic atomization device in this embodiment includes a housing 1, an atomization module 2, a main control module 3, a fixing seat 4 and an airflow sensor (not shown), the top of the housing 1 is provided with a suction nozzle 11, the bottom of the housing 1 is provided with an air inlet groove 12, the atomization module 2 and the main control module 3 are fixed side by side in the housing 1, the atomization module 2 includes an air inlet end 21 and an air outlet end 22 arranged oppositely, the air outlet end 22 is connected to the suction nozzle 11, the fixing seat 4 is arranged at one end of the atomization module 2 away from the suction nozzle 11, the fixing seat 4 is provided with an air inlet channel 41, the two ends of the air inlet channel 41 are respectively connected to the air inlet groove 12 and the air inlet end 21, the fixing seat 4 is also provided with a mounting groove 42, the airflow sensor is fixed in the mounting groove 42, the bottom end of the mounting groove 42 is provided with an air inlet flow channel 43 connected to the air inlet end 21, and the atomization module 2 and the airflow sensor are respectively electrically connected to the main control module 3. Compared with the atomization module 2 and the main control module 3 being distributed up and down, the atomization module 2 and the main control module 3 are arranged side by side in the outer shell 1, and the two components are independent of each other and do not interfere with each other. The atomization module 2 is closer to the air inlet groove 12, and there is no obstruction between the air inlet end 21 of the atomization module 2 and the air inlet groove 12. The airway is short and the air intake is fast. The airflow sensor can quickly detect the airflow change to start the atomization module 2. The condensate flowing out of the atomization module 2 will not drip onto the main control module 3, thereby ensuring the safety of the main control module 3.

[0032] In one possible implementation, see Figure 2-Figure 5 The electronic atomization device also includes a mounting seat 6 that matches the fixing seat 4. The mounting seat 6 is provided with a groove 61 on one side of the fixing seat 4. The bottom of the groove 61 is provided with an air inlet 62 that is connected to the air inlet groove 12. The airflow sensor and the air inlet channel 41 are respectively located above the groove 61. The side wall of the fixing seat 4 is tightly fitted with the side wall of the mounting seat 6. The airflow entering the mounting seat 6 through the air inlet groove 12 can only be gathered by the air inlet channel 41 and flow out to the atomization module 2 to ensure sufficient air intake. Since the fixing seat 4 and the mounting seat 6 have the same shape and size and the joint of the two structures forms a tight connection, the gas entering the mounting seat 6 cannot overflow to the main control module 3, reducing the volume of the gas flow. The airflow sensor can sensitively detect the change of the airflow to trigger the atomization module 2 to work.

[0033] Furthermore, the groove 61 is provided with a protruding block 63 at the position of the air inlet groove 12, and the air inlet hole 62 penetrates the air inlet hole 62 along the height direction of the protruding block 63. A protruding block 63 is provided at the bottom of the groove 61, and the air inlet hole 62 penetrates the entire protruding block 63. When the air inlet of the mounting seat 6 is unobstructed, the groove 61 also forms a liquid storage tank, and the condensed liquid flowing out of the atomization module 2 can fall back and be stored in the groove 61 to prevent the liquid from leaking directly out. Of course, in order to improve the liquid storage capacity of the groove 61, oil-absorbing cotton (not shown) is padded around the side of the groove 61 around the protruding block 63.

[0034] In one possible implementation, see Figure 2 and Figure 3 The electronic atomization device further includes an air regulating plate 65, which is provided with air vents 64. The number of the air vents 64 and the number of the air inlet holes 62 are the same. In this embodiment, the number of the air vents 64 is at least two, the air inlet slot 12 is rectangular, and the cross-sectional area of ​​the air inlet slot 12 is much larger than the total cross-sectional area of ​​the air vents 64. The air regulating plate 65 is slidably mounted on the position of the housing 1 at the air inlet slot 12. In this way, the air intake of the electronic atomization device can be adjusted by sliding the air regulating plate 65 to control the shielding area of ​​the air inlet hole 62, so as to meet the air intake requirements of different working modes of the electronic atomization device and ensure the suction effect.

[0035] In a possible embodiment, the atomization module 2 includes an oil storage cotton 23, two groups of heating meshes 24 and pins 25. The two groups of heating meshes 24 are spaced apart along the height direction of the oil storage cotton 23, and the pins 25 include a common pin 25 connected to one end of the two heating meshes 24 and two independent pins 25 respectively connected to the other ends of the two groups of heating meshes 24, and the two independent pins 25 and the common pin 25 are respectively electrically connected to the main control module 3 through the fixing seat 4. Here, two groups of heating meshes 24 are configured in the atomization module 2, and the two groups of heating meshes 24 can work in turn to extend the service life of the heating meshes 24. Of course, the two groups of heating meshes 24 can also work synchronously to meet the user's pursuit of large smoke and large explosion.

[0036] In one possible implementation, see Figure 2, the main control module 3 includes a battery 31, a main control board 32 and a display screen 33. A buckle position (not shown) is provided on one side of the atomization module 2 in the housing 1. The battery 31 is cylindrical, and the battery 31 is vertically embedded in the buckle position. The main control board 32 and the display screen 33 are stacked on the battery 31 in sequence, and the housing 1 is provided with a mounting position 13 corresponding to the position of the display screen 33, and part of the display screen 33 is embedded in the mounting position 13. The display screen 33 is fixed in the mounting position 13, and the display screen 33 is not easy to loosen or fall off even if it is hit by external force. In order to ensure the overall aesthetic performance of the electronic atomization device, the display screen 33 is flush with the outer side of the housing 1, without protrusions and depressions. The display screen 33 is electrically connected to the main control board 32, and the display screen 33 can display the working condition, remaining power and remaining amount of smoke oil of the atomization module 2 in real time, so that the user can plan in advance. Of course, the display screen 33 can also be a touch screen, and the user can control the working condition of the electronic cigarette through the display screen 33. The display screen 33 can also be equipped with different animation displays according to different working modes.

[0037] Specifically, the end of the main control board 32 close to the air inlet passage 41 is the bottom end of the main control board 32, and a transfer board 34 is provided at the bottom end of the main control board 32. The transfer board 34 is horizontally distributed in the housing 1 and is perpendicular to the main control board 32. A USB interface 35 is provided at one end of the transfer board 34, and a corresponding avoidance port (not shown) is provided at the bottom end of the housing 1. At least part of the USB interface 35 extends out of the avoidance port to connect with an external medium. Figure 2 As shown, the USB interface 35 and the air inlet groove 12 are spaced apart at the bottom of the housing 1. Compared with the air inlet groove 12 integrating the USB interface 35, the air inlet groove 12 is set independently from the USB interface 35, which can avoid the problem of gas blowby or the components of the USB interface 35 blocking the air intake, thereby ensuring smooth ventilation of the air inlet channel 41.

[0038] In one possible implementation, see Figure 2 The housing 1 is provided with a perspective window at the atomization module 2, and a transparent cover plate 5 is provided at the perspective window in a C shape. The atomization module 2 includes a transparent or translucent oil cup 26. In this way, the user can directly observe the remaining smoke oil in the oil cup 26 through the cover plate 5.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
