In a specific embodiment, the positions of the first air inlet hole 125 and the second air inlet hole 127 in the central axis direction of the atomizer 1 are asymmetrically arranged, or the positions of the first air inlet hole 125 and the second air inlet hole 127 in the direction perpendicular to the central axis of the atomizer 1 are asymmetrically arranged, and the heights of the first air inlet hole 125 and the second air inlet hole 127 in the central axis direction of the atomizer 1 are not consistent, or the widths of the first air inlet hole 125 and the second air inlet hole 127 in the direction perpendicular to the central axis of the atomizer 1 are not consistent.

In an embodiment, please refer to fig. 9(a) to 9(c), fig. 9(a) is a fitting diagram of an embodiment of the airflow state in the atomizing chamber and the air outlet channel of the atomizer according to the present invention; fig. 9(b) is a schematic fitting diagram of an embodiment of the aerosol state in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; fig. 9(c) is a graph of the passage rate of large droplets in the atomizer provided in fig. 9(b) versus the size of the first and/or second air intake holes. When the heights of the first air intake holes 125 and the second air intake holes 127 in the direction of the central axis of the atomizer 1 are not uniform, or when the widths of the first air intake holes 125 and the second air intake holes 127 in the vertical direction of the central axis of the atomizer 1 are not the same, the areas of the air inlets of the first air intake holes 125 and the second air intake holes 127 are not the same, there is a difference between the flow rate of the air introduced into the atomizing chamber 133 through the first air introducing holes 125 and the flow rate of the air introduced into the atomizing chamber 133 through the second air introducing holes 127, so that the two airflows respectively entering the atomizing chamber 133 through the first and second air intake holes 125 and 127 more easily form spirally rising airflows, and then closely contact with the inner wall of the atomizing chamber 133, so that the large liquid droplets in the aerosol are more attached to the inner wall of the atomizing chamber 133 and the inner wall of the air outlet channel 113 due to the centrifugal force in the spiral ascending process, and the passing rate of the large liquid droplets in the aerosol is further reduced. Wherein, the particle diameter of the large liquid drop is 10-170 um.

In another embodiment, please refer to fig. 10(a) to 10(c), fig. 10(a) is a fitting diagram of an embodiment of the airflow state in the atomizing chamber and the air outlet channel of the atomizer according to the present invention; FIG. 10(b) is a schematic diagram showing a fit of another embodiment of the invention to the state of the sol in the nebulization chamber and the outlet channel of the nebulizer;

fig. 10(c) is a graph of the passage rate of large droplets in the atomizer provided in fig. 10(b) versus the size of the first and/or second air intake holes. When the first air inlet hole 125 and the second air inlet hole 127 are oppositely arranged and the central axes coincide, but the height of the first air inlet hole 125 in the direction of the central axis of the atomizer 1 is greater than the height of the second air inlet hole 127, and the width of the second air inlet hole 127 in the direction perpendicular to the central axis of the atomizer 1 is greater than the width of the first air inlet hole 125, so that the sizes of the first air inlet hole 125 and the second air inlet hole 127 are inconsistent. The air flow rate entering the atomizing cavity 133 through the first air inlet hole 125 and the air flow rate entering the atomizing cavity 133 through the second air inlet hole 127 are different, so that two air flows respectively entering the atomizing cavity 133 through the first air inlet hole 125 and the second air inlet hole 127 are easier to form spirally-rising air flows, and further are in close contact with the inner wall of the atomizing cavity 133, so that large liquid drops in the aerosol are more attached to the inner wall of the atomizing cavity 133 and the inner wall of the air outlet channel 113 due to the action of centrifugal force in the spirally-rising process, and the passing rate of the large liquid drops in the aerosol is further reduced. Wherein, the particle diameter of the large liquid drop is 10-170 um.

In another embodiment, please refer to fig. 11, fig. 11 is a graph showing a relationship between a passing rate of large liquid droplets and sizes of the first air inlet hole and/or the second air inlet hole in another embodiment of the atomizer according to the present invention.

The airflow direction entering the atomizing cavity 133 through the first air inlet 125 and the airflow direction entering the atomizing cavity 133 through the second air inlet 127 both rotate around the central axis direction of the atomizer 1, so that two airflows entering the atomizing cavity 133 through the first air inlet 125 and the second air inlet 127 respectively form spirally-rising airflows more easily, and further contact with the inner wall of the atomizing cavity 133 closely, so that large liquid drops in aerosol are attached to the inner wall of the atomizing cavity 133 and the inner wall of the air outlet channel 113 more due to the action of centrifugal force in the spirally-rising process, and the passing rate of the large liquid drops in aerosol is reduced. Wherein, the particle diameter of the large liquid drop is 10-170 um.
