[0039] See also Figure 1 to Figure 4 , the electronic cigarette provided in this embodiment is now described. The electronic cigarette 100 in this embodiment includes a shell 1, a bottom cover 2, an atomization module 3, a mounting bracket 4, an airflow sensor 8 and a battery 5. One end of the shell 1 has a mouthpiece 11, and the other end has an opening (not shown). The bottom cover 2 is sealed at the opening of the shell 1, and the bottom cover 2 has an air inlet 21. The atomization module 3 and the mounting bracket 4 are inserted into the shell 1 from the opening in turn. The battery 5 is fixed on the mounting bracket 4 and is electrically connected to the atomization module 3 and the airflow sensor 8 respectively. The atomization module 3 has a first air inlet channel 31, which extends along the longitudinal direction of the atomization module 3. The air outlet end of the first air inlet channel 31 is connected to the mouthpiece 11, and the mounting bracket 4 extends from the air inlet hole 21 of the bottom cover 2 to the air inlet end of the first air inlet channel 31 to form a second air inlet channel 42. A groove 43 is provided at the outer wall of the mounting bracket 4 near one end of the atomizing module 3, and the airflow sensor 8 is fixed in the groove 43. The mounting bracket 4 is provided with an airflow channel 44 at the bottom of the groove 43 toward the central axis of the mounting bracket 4. The airflow channel 44 is distributed between the first air inlet channel 31 and the second air inlet channel 42, and is connected with the two air inlet channels. Then, the airflow sensor 8 located at one end of the airflow channel 44 can monitor the air pressure change in the housing 1 in real time to start the atomizing module 3.

[0040] In this embodiment, the first air inlet channel 31 and the second air inlet channel 42 are combined to form the air inlet channel of the electronic cigarette 100, and the air inlet channel extends longitudinally along the shell 1. The airflow sensor 8 is fixed on the outside of the mounting bracket 4, and the atomization module 3 is fixed above the mounting bracket 4. The airflow sensor 8 is located on the outside of the atomization module 3, and an airflow channel 44 is provided at the mounting bracket 4, which is connected to the airflow sensor 8 at one end and connected to the air inlet channel at the other end. Compared with installing the airflow sensor 8 below the atomization module 3, this design can reduce the leakage of condensate flowing out of the atomization module 3 to the airflow sensor 8, thereby ensuring the sensitivity and service life of the airflow sensor 8.

[0041] In a possible embodiment, the mounting bracket 4 has a mounting groove 41 at one end for the atomization module 3 to be placed, and the mounting groove 41 is located at the port of the second air inlet channel 42 and is provided with an annular baffle 45. The annular baffle 45 surrounds the port of the second air inlet channel 42, but does not completely surround the second air inlet channel 42, and the air flow channel 44 extends from the inner side wall of the mounting groove 41 away from the annular baffle 45 toward the groove 43. Among them, part of the air flow channel 44 close to the groove 43 is arranged higher than the bottom of the mounting groove 41. It can be understood that the atomization module 3 is fixed above the mounting bracket 4, the mounting bracket 4 is provided with a groove 43 below the atomization module 3, the airflow sensor 8 is fixed on the outside of the mounting bracket 4, and the mounting bracket 4 is provided with an airflow channel 44 connecting the atomization module 3 and the airflow sensor 8. A similar slope structure is provided at the airflow channel 44, so that at least part of the airflow channel 44 is higher than the bottom of the groove 43, and the condensate falling from the atomization module 3 into the groove 43 is difficult to climb over the slope and enter the airflow sensor 8, thereby ensuring the sensitivity of the airflow sensor 8. An annular baffle 45 is provided at the second air inlet channel 42, and the annular baffle 45 can prevent the condensate from entering the second air inlet channel 42. Of course, the electronic cigarette 100 also includes oil-absorbing cotton 46, which is fixed in the mounting groove 41 and surrounds the annular baffle 45. The oil-absorbing cotton 46 can absorb the condensate dripping from the first air inlet channel 31.

[0042] Specifically, the airflow channel 44 includes a first airflow channel 441 extending transversely from the bottom of the groove 43 toward the central axis of the mounting bracket 4 and a second airflow channel 442 bent downward from the free end of the first airflow channel 441 toward the second air inlet channel 42. Figure 4 As shown, the first airflow channel 441 is horizontally distributed on the mounting bracket 4 from outside to inside, the second airflow channel 442 is extended downward along the height direction of the mounting bracket 4, and the outer side wall of the second airflow channel 442 also has an air guide hole 443, and an angle is formed between the first airflow channel 441 and the second airflow channel 442. Preferably, the angle between the two airflow channels 44 is a right angle, that is, a corner is formed in the airflow channel 44, so that the condensate flowing out of the atomization module 3 is difficult to flow from the airflow channel 44 to the airflow sensor 8.

[0043] In this embodiment, a mounting groove 41 is provided at the top of the mounting bracket 4, the airflow sensor 8 is fixed on the outside of the mounting bracket 4, and an airflow channel 44 is provided in the mounting bracket 4 to connect the first air inlet channel 31 and the second air inlet channel 42. Among them, the part of the airflow channel 44 connected to the airflow sensor 8 is arranged higher than the bottom of the mounting groove 41, so that it is difficult for the condensate flowing out of the first air inlet channel 31 to enter the airflow sensor 8 through the airflow channel 44, and at least one corner structure is provided in the airflow channel 44, which increases the difficulty of the condensate entering the airflow channel 44, thereby preventing the condensate from contaminating the airflow sensor 8.

[0044] See also Figure 1 and Figure 2 , the first air inlet channel 31 and the second air inlet channel 42 extend longitudinally along the atomizer and the mounting bracket 4, respectively. Viewed along the longitudinal direction of the electronic cigarette 100, the first air inlet channel 31 and the second air inlet channel 42 are respectively arranged in a straight cylindrical shape, and the center lines of the first air inlet channel 31 and the second air inlet channel 42 are staggered with each other. That is, the first air inlet channel 31 and the second air inlet channel 42 are partially staggered or completely staggered. The air inlet channel is arranged in a straight cylindrical shape, the air inlet channel is unobstructed, the air intake is stable and fast, and the airflow sound during the air intake is reduced. However, the first air inlet channel 31 and the second air inlet channel 42 are staggered, which can prevent the condensate sliding from the first air inlet channel 31 from directly entering the second air inlet channel 42. Furthermore, the mounting bracket 4 can be provided with an oil-absorbing medium for absorbing the condensate, such as oil-absorbing cotton 46, at the intersection of the first air inlet channel 31 and the second air inlet channel 42.

[0045] In one possible embodiment, Figure 3 As shown, a receiving groove 47 is provided in the middle of the mounting bracket 4, and the battery 5 is received in the receiving groove 47, and the second air inlet channel 42 is located on one side of the receiving groove 47. Here, the second air inlet channel 42 is isolated from the battery 5, so that the airflow flows in the second air inlet channel 42, the first air inlet channel 31 and the air inlet channel, avoiding the influence of other structures and materials on the airflow, and improving the stability and cleanliness of the airflow. Since the second air inlet channel 42 is completely independent of the battery 5, the condensate flowing out of the atomization module 3 can be prevented from soaking the battery 5, thereby ensuring the service life of the battery 5.

[0046] In a possible embodiment, the electronic cigarette 100 also includes a display screen 6 and a main control board 7. The main control board 7 is vertically installed in the shell 1 and is respectively located on one side of the atomization module 3 and the mounting bracket 4. A positioning piece, such as a buckle, a screw, etc., is protruding outward from the middle of the mounting bracket 4. The positioning piece can combine the main control board 7 and the mounting bracket 4 into a whole, thereby improving the stability of the installation of the main control board 7. An opening (not shown) is provided on the side of the shell 1 corresponding to the atomization module 3, and the display module is stacked on the side of the main control board 7 away from the atomization module 3. The interactive surface of the display screen 6 is exposed to the outside through the opening. Figure 1 As shown, the electronic cigarette 100 is cylindrical, and the display screen 6 can be a flexible curved screen. The display screen 6 is exposed on the outer wall of the shell 1, and the display screen 6 extends from the mouthpiece 11 of the shell 1 to the middle of the shell 1, meeting the demand for the electronic cigarette 100 to have a large screen. On the one hand, the display screen 6 can display various parameters of the electronic cigarette 100 in real time, such as the number of puffs, the amount of remaining e-liquid, the remaining power value, temperature, voltage, time, date, etc., which can effectively help users better monitor the habits and preferences of using the electronic cigarette 100, and users can also quickly obtain various energy consumption conditions in the electronic cigarette 100, make plans in advance, avoid accidentally consuming the e-liquid and power, and improve the experience; on the other hand, the display screen 6 is a tool for human-computer interaction, and users can adjust the output power and working mode of the electronic cigarette 100 through the display screen 6.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

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.
