When the height range is larger than 1.5mm, the introduced airflow cannot contact the atomization surface 214, and the problem of carbonization of the heating film can occur; if the height range is less than 0.5mm, the problem that the air inflow is insufficient and the aerosol quantity is insufficient occurs. In this embodiment, the air guiding direction of the air guiding groove 2121 can be aligned with the position where the temperature of the heating element 222 is highest, that is, aligned with the bending portion 2221.

In this embodiment, the air inlet area of the single air guide groove 2121 can be 0.6mm²～1.5mm²In the meantime. Wherein, when the air inlet area is less than 0.6mm²If so, the air inflow is insufficient; when the air inlet area is more than 1.5mm²Dispersion of the mist occurs so that the amount of atomization is reduced. The sum of the air inlet areas of the two air guide grooves 2121 can be 0.8mm²～3.0mm²Thereby improving the air input and further improving the atomized gas amount.

As shown in fig. 3 and fig. 9, in the present embodiment, the base 23 may include a seat 231 disposed on the seat 231 and a matching portion 232 matching with the atomizing base 21, the cross section of the seat 231 may be substantially elliptical, and the seat 231 may be inserted into the opening end of the housing 1 to close the opening of the housing 1. Of course, it is understood that in other embodiments, the seat 231 may not be limited to having an oval shape. The seat 231 can be snap-connected to the housing 1, and in some embodiments, two opposite sidewalls of the seat 231 can be provided with a snap 2311, and the seat 231 can be snap-connected to the housing 1 through the snap 2311. In the embodiment, the base 23 may be provided with two air inlets 2312, specifically, the air inlets 2312 may be provided on the seat 231, and the two air inlets 2312 may be distributed on the short axis of the seat 231 and may be respectively communicated with the air storage cavity 215. In this embodiment, the base 231 may further include two first through holes 2313, and the two first through holes 2313 may be disposed at intervals for the two electrode elements 24 to be correspondingly mounted one by one. In this embodiment, the base 231 may further include two second through holes 2313, and the two second through holes 2312 may be located at two opposite sides of the two first through holes 2313, and may be used for the magnetic attraction member 25 to be mounted. The matching portion 232 can be disposed at one end of the seat 231 for the second engaging portion 2112 of the atomizing seat 21 to engage. In some embodiments, a supporting structure 2312 may be further disposed at one end of the engaging portion 232, the supporting structure 2312 may be inserted into the atomizing base 231 and may be used for supporting the heat generating component 22, in this embodiment, the supporting structure 2312 may include two oppositely disposed supporting arms, and the two supporting arms may be respectively inserted from the atomizing base 21 and may be located at two opposite sides of the heat generating component 22.

In this embodiment, the atomizing assembly 2 may further include two electrode elements 24, and the two electrode elements 24 may be respectively in one-to-one corresponding conductive connection with the two conductive connection portions 223 on the heating assembly 22. The two electrode members 24 are correspondingly disposed in the first through holes 2313 to electrically connect the heating element 22 and the power element.

In this embodiment, the atomizing assembly 2 may further include two magnetic attraction members 25, the two magnetic attraction members 25 may be installed in the two second through holes 2314 in a one-to-one correspondence, and the whole atomizer may be fixed to the power supply assembly in an attraction manner.

Fig. 10 to 12 show a second embodiment of the electronic atomizer of the present invention, which is different from the first embodiment in that two air guide grooves 2121 are arranged in parallel and on a straight line, and the shape of the atomizing chamber 214 is different. In this embodiment, the atomizing chamber 214 may be substantially rectangular parallelepiped. The first connecting portion 2141 may be a flat surface, the second connecting portion 2142 may be an arc surface, and the third connecting portion 2143 may be a flat surface.

After the airflow is guided to the atomizing surface 214 by the air guide structure 2120, the flow direction of the airflow can be changed by using different shapes of atomizing cavities, and this first embodiment is smoother than this second embodiment because the structures of the air inlet transition section and the air outlet channel 213 are substantially the same in the first embodiment and the second embodiment, but the design of the atomizing cavity 214 is different in that the horizontal included angle of the speed of the airflow entering the atomizing cavity 214 from the transition section (the second connecting portion 2142) is different, and the shape of the transition section (the second connecting portion 2142) entering the air outlet channel 213 from the atomizing cavity 214 is different, so that the uniformity and the flowability of the airflow are different.

As shown in fig. 13 and 14, the resistance to suction of the air passages of the first and second embodiments is mainly caused by two locations of the air intake passage and the transition section (second connecting portion 2142) into the atomizing chamber 214; the suction resistance of the first embodiment is 713.5Pa, the suction resistance of the second embodiment is 918.3Pa, and the suction resistance of the second embodiment is increased by 28.7% compared with the suction resistance of the first embodiment, so that the main reason why the suction resistance of the first embodiment is small is that the cross-sectional area of the inlet passage of the atomizing chamber 214 is large, the local resistance loss of air entering the atomizing chamber 214 is small, the outlet air passage of the atomizing chamber 214 is smoother, the generated vortex is small, and the resistance loss is small.

As shown in fig. 15 and 16, compared with the first embodiment, the atomizing chamber 214 of the second embodiment has two larger swirl areas, the swirl of the area 1 causes the suction resistance of the air passage to increase, the condensation of the atomizing gas to be intensified, the swirl of the area 2 causes the atomizing medium to be taken away in time, and the temperature of the heating element is too high.

As shown in fig. 17 and 18, since the two air guide grooves 2121 of the atomizing chamber 214 of the second embodiment are on the same straight line, after the air enters the atomizing chamber 214 from the two air inlets, a "stagnation region" appears at the middle position of the heating element, a large vortex (shown by the dotted line frame in the above figure) is generated, and most of the air flow is directly discharged to the air outlet channel without being diffused by the onion powder in the atomizing chamber 214. The air guide grooves 2121 of the first embodiment are staggered with each other, so that air is fully diffused after entering the atomizing chamber 214, the velocity distribution of the heating element region is more uniform, and the air can be fully mixed with the atomized liquid atomizing medium and then flows out of the atomizing chamber 214.

From the above analysis, it can be seen that the airflow mixing is more uniform and the flow is smoother in the first embodiment compared to the second embodiment.
