In this embodiment, the liquid absorbing member housing chamber 13 includes a first region 221 corresponding to the first stage air passage 11 and a second region 222 corresponding to the second stage air passage 12; it is defined that the end of the first rib 2121 near the first segment air duct 11 in the first region 221 is at a first distance L1 from the central axis of the first segment air duct 11, the end of the first rib 2121 near the first segment air duct 11 in the second region 222 is at a second distance L2 from the central axis of the first segment air duct 11, and the first distance L1 is greater than the second distance L2, that is, the height of the first rib 2121 in the second region 222 is greater than the height of the first rib 2121 in the first region 221.

In the experiment, the side wall surface of the opening of the experimental piece is attached to the acrylic plate, so that the liquid flow can be observed conveniently.

The extending direction of the first ribs 2121 and the extending direction of the first segment of air duct 11 form an included angle of 60 to 90 degrees, so that the liquid can smoothly flow into the second space 23 through the first capillary grooves 2122. Preferably, the extending direction of the first ribs 2121 forms an angle of 90 degrees with the extending direction of the first segment of the air duct 11.

By providing a plurality of first ribs 2121 in the wicking element receiving chamber 13, the liquid flowing into the actuation channel 1 is guided such that the liquid is absorbed by the porous liquid storage element 211.

In order to avoid the formation of the capillary action between the plurality of first ribs 2121 in the second region 222, which affects the liquid entering the first capillary grooves 2122 formed by the plurality of first ribs 2121 in the first region 221, the plurality of second distances L2 of the plurality of first ribs 2121 disposed in the second region 222 may form an equal difference decreasing in the direction from away from the first region 221 to close to the first region 221. Liquid spreads over the porous reservoir element 211 in a direction from away from the first region 221 to near the first region 221.

When the amount of the leakage liquid is small, the liquid flowing into the starting channel 1 is guided by the plurality of first ribs 2121 and absorbed by the porous liquid storage element 211, so that the smoothness of the starting channel 1 is not affected.

Fig. 15 is a diagram of an experimental image of the starting channel 1 of the electronic atomization device provided in fig. 14.

In this experiment, the plurality of second distances L2 of the plurality of first ribs 2121 disposed in the second region 222 decrease along the direction from the first region 221 to the first region 221, so as to avoid the formation of capillary action between the plurality of first ribs 2121 in the second region 222, which affects the liquid entering into the first capillary grooves 2122 and the second capillary grooves 2124 formed by the plurality of first ribs 2121 in the first region 221. In the experiment, the side wall surface of the opening of the experimental piece is attached to the acrylic plate, so that the liquid flow can be observed conveniently.

In the fifth embodiment, a plurality of first ribs 2121 and a plurality of second ribs 2123 are provided in one-to-one correspondence. The extending directions of the first ribs 2121 and the second ribs 2123 form an angle of 60-90 degrees with the extending direction of the first segment of the air duct 11, so that the liquid can smoothly flow into the second space 23 through the first capillary grooves 2122 and the second capillary grooves 2124. Preferably, the extending direction of the first ribs 2121 and the second ribs 2123 forms an angle of 90 degrees with the extending direction of the first segment of the air duct 11.

By providing a plurality of first ribs 2121 and a plurality of second ribs 2123 within the wicking element receiving chamber 13, fluid flowing into the actuation channel 1 is directed such that the fluid is absorbed by the porous reservoir element 211. By dividing the liquid absorbing member accommodating chamber 13 into the first region 221 corresponding to the first air passage 11 and the second region 222 corresponding to the second air passage 12, the liquid entering the actuation passage 1 through the interface of the second air passage 12 communicating with the nebulizing passage 5 can more smoothly enter the first capillary groove 2122 and the second capillary groove 2124 by setting the first distance L1 to be greater than the second distance L2. In order to avoid the formation of the capillary action between the plurality of first ribs 2121 in the second region 222, which affects the liquid entering the first capillary grooves 2122 and the second capillary grooves 2124 formed by the plurality of first ribs 2121 in the first region 221, the plurality of second distances L2 of the plurality of first ribs 2121 disposed in the second region 222 may be formed to decrease in equal difference in the direction from being far from the first region 221 to being close to the first region 221. By forming the third capillary groove 2125 between the first ribs 2121 and the second ribs 2122, the liquid is prevented from forming an air column in the first capillary groove 2122 or the second capillary groove 2124, which may affect the absorption of the liquid by the porous liquid storage element 211. Liquid spreads over the porous reservoir element 211 in a direction from away from the first region 221 to near the first region 221.

When the amount of the leakage liquid is small, the liquid flowing into the starting channel 1 is guided by the plurality of first fins 2121 and the plurality of second fins 2123 to be absorbed by the porous liquid storage element 211, so that the smoothness of the starting channel 1 is not affected. When the amount of the liquid leakage is large, the liquid flowing into the starting channel 1 is firstly guided to the porous liquid storage element 211 by the first ribs 2121 and the second ribs 2123, and the porous liquid storage element 211 does not have liquid absorption capacity, the liquid level in the second section of the air passage 12 is further lifted, so that the through hole 111 communicated with the airflow sensor 2 is an area which is contacted with the liquid finally, and the airflow sensor 2 is protected to the maximum. In the use, porous stock solution component 211 absorbs liquid or changes porous stock solution component 211 after the imbibition speed slows down, can avoid liquid to stay in starting passageway 1 as far as, and then avoids liquid to soak air current sensor 2, promotes electronic atomization device's performance.

In the second, third, fourth, and fifth embodiments, the capillary force of the capillary grooves far from the airflow sensor 2 is larger than that of the capillary grooves near the airflow sensor 2, so that more leakage liquid can be stored far from the airflow sensor 2. The capillary drainage structure 212 may include a plurality of first ribs 2121 and/or a plurality of second ribs 2123, and the material of the plurality of first ribs 2121 and the plurality of second ribs 2123 is metal or ceramic. When the capillary drainage structure 212 comprises porous ceramic and the porous liquid storage element 211 is porous ceramic, the capillary force of the capillary drainage structure 212 is different from the capillary force of the porous liquid storage element 211.

According to the invention, the liquid suction part 21 is arranged in the starting channel 1, and the liquid suction part 21 sucks liquid flowing through the starting channel 1 through capillary force, so that liquid leakage is prevented from soaking the airflow sensor 2, the failure of the airflow sensor is avoided, and meanwhile, the smoothness of the starting channel 1 is ensured.
