10 to 12 show the second embodiment of the electronic atomization device of the present invention, which is different from the first embodiment in that the two air guide grooves 2121 are arranged in parallel and on a straight line, and the atomization The cavity 214 is shaped differently. In this embodiment, the atomizing cavity 214 can be roughly in the shape of a rectangular parallelepiped with rounded corners. 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 air flow is guided to the atomizing surface 214 by the air guide structure 2120, the flow direction of the air flow can be changed by using different shapes of atomizing chambers. Compared with the second embodiment, the first embodiment has The air flow is smoother, because although the structures of the air inlet adapter section and the air outlet channel 213 are roughly the same in the first embodiment and the second embodiment, the design of the atomizing cavity 214 is different. The main difference is that the air flow is caused by the adapter section. (The second connecting part 2142) enters the atomizing cavity 214 with different speed and horizontal angles, and the shape of the transition section (the second connecting part 2142) from the atomizing cavity 214 entering the air outlet channel 213 is different, so that the uniformity of the airflow and the The fluidity is different. Specifically, please refer to the comparative analysis of the pressure field and the velocity field of the first embodiment and the second embodiment.

As shown in FIG. 13 and FIG. 14 , the suction resistance of the air passages of the first embodiment and the second embodiment is mainly composed of two parts: the air inlet passage and the transition section (the second connection part 2142 ) entering the atomizing chamber 214 As a result, the suction resistance of the first embodiment is 713.5Pa, and the suction resistance of the second embodiment is 918.3Pa. Compared with the suction resistance of the first embodiment, the suction resistance of the second embodiment is increased by 28.7%. The main reason for the low suction resistance in one embodiment is that the cross-sectional area of the inlet channel of the atomizing chamber 214 is large, the local resistance loss of air entering the atomizing chamber 214 is small, the outlet airway of the atomizing chamber 214 is smoother, and the generated vortex is small. , the resistance loss is small.

As shown in FIG. 15 and FIG. 16 , compared with the first embodiment, the atomizing chamber 214 of the second embodiment has two large vortex areas. The vortex in the area 1 will increase the suction resistance of the airway and cause the atomization to increase. The gas condensation is intensified, and the vortex in the area 2 will cause the atomization medium to be unable to be taken away in time, and the temperature of the heating element will be too high.

As shown in FIG. 17 and FIG. 18 , since the two air guide grooves 2121 of the atomizing chamber 214 of the second embodiment are on the same straight line, the air enters the atomizing chamber 214 from the two air inlets respectively, and then enters the atomizing chamber 214 in the middle. A "stagnant area" appears at the position of the heating element, which generates a large vortex (as shown by the dotted box in the above figure). However, the air guide grooves 2121 of the first embodiment are staggered, so that the air enters the atomizing chamber 214 and diffuses fully, and the velocity distribution in the heating body area is more uniform, which can be fully mixed with the atomizing liquid atomizing medium and then flow out of the atomizing chamber 214. .

Based on the above analysis, it can be seen that, compared with the second embodiment, the air flow in the first embodiment is more evenly mixed and the flow is smoother.

It can be understood that the above examples only represent the preferred embodiments of the present invention, and their descriptions are more specific and detailed, but should not be construed as a limitation on the scope of the patent of the present invention; In other words, without departing from the concept of the present invention, the above-mentioned technical features can be freely combined, and some deformations and improvements can be made, and these all belong to the protection scope of the present invention; All equivalent transformations and modifications made shall fall within the scope of the claims of the present invention.
