One end of the mounting seat 12 has an air outlet hole 132 and a lower liquid hole 131, and the air outlet hole 132 and the lower liquid hole 131 are arranged at intervals. The air outlet hole 132 is arranged opposite to the air outlet channel 113 and is connected. The part of the air outlet hole 132 located between the air outlet channel 113 and the atomizing core 16 cooperates with the atomizing core 16 to form the atomizing cavity 133, and the first air inlet portion 124 and the second air inlet portion 126 are arranged on the side wall of the mounting seat 12 that does not belong to the lower liquid hole 131. In a specific embodiment, the mounting base 12 includes an upper body 121 and a lower body 141 fixedly connected to the upper body 121. The upper body 121 is disposed close to the liquid storage chamber 111, and the lower body 141 is disposed on a side of the upper body 121 away from the liquid storage chamber 111. The upper body 121 and the lower body 141 cooperate to form an installation space, and the installation space is used to accommodate the atomizer core 16.

[0053] The upper seat body 121 includes an annular side wall 122 and a top wall 130 connected to the annular side wall 122. A lower liquid hole 131 and an air outlet hole 132 are provided on the top wall 130, and the lower liquid hole 131 and the air outlet hole 132 are arranged at intervals. In a specific embodiment, part of the annular side wall 122 and the outer wall of the air outlet hole 132 surround the lower liquid hole 131, and one end of the lower liquid hole 131 is connected to the liquid storage chamber 111, and the other end is connected to the installation space. One end of the air outlet hole 132 is connected to the air outlet channel 113, and the other end is connected to the installation space. Among them, the inner diameter of the air outlet channel 113 may not be less than the inner diameter of the air outlet hole 132 near the end of the air outlet channel 113. In an optional embodiment, the inner diameter of the air outlet channel 113 is equal to the inner diameter of the end of the air outlet hole 132 forming the atomization chamber 133 and close to the air outlet channel 113. The inner diameter of the part of the air outlet hole 132 where the air outlet channel 113 is installed is greater than the inner diameter of the end of the air outlet hole 132 forming the atomizing chamber 133 and close to the air outlet channel 113. In an optional embodiment, the end of the air outlet channel 113 can be closely abutted against the side of the top wall 130 away from the annular side wall 122. Among them, a first sealing member 191 is provided between the air outlet channel 113 and the upper seat body 121, and the first sealing member 191 is used to seal the gap between the air outlet channel 113 and the air outlet hole 132, and is also used to seal the gap between the upper seat body 121 and the inner wall of the housing 11, so as to avoid the matrix to be atomized in the liquid storage chamber 111 from leaking out of the gap formed by the cooperation between the air outlet channel 113 and the air outlet hole 132, and also to avoid the matrix to be atomized from leaking out of the gap formed by the cooperation between the upper seat body 121 and the inner wall of the housing 11. Among them, the material of the first sealing member 191 is silicone.

[0054] In a specific embodiment, the atomizing chamber 133 includes a first cavity 134 and a second cavity 135, and the first cavity 134 and the second cavity 135 are connected to each other. The first cavity 134 is arranged near the part where the air outlet hole 132 connects to the air outlet channel 113, and the first cavity 134 is connected to the air outlet channel 113, for example, one end of the air outlet channel 113 is inserted into the first cavity 134. The second cavity 135 is arranged on the side of the first cavity 134 away from the air outlet channel 113. The second cavity 135 is a columnar structure. In other words, the inner diameter of the end of the second cavity 135 connected to the first cavity 134 is equal to the inner diameter of the end of the second cavity 135 away from the first cavity 134. From the end of the first cavity 134 connecting the second cavity 135 to the end of the first cavity 134 away from the second cavity 135, the cross section of the first cavity 134 gradually shrinks into a shrinking structure. That is to say, the inner diameter of the end of the first cavity 134 connected to the second cavity 135 is greater than the inner diameter of the end of the first cavity 134 away from the second cavity 135. The inner diameter of the end of the first cavity 134 away from the second cavity 135 is equal to the inner diameter of the air outlet channel 113. In one specific embodiment, the inner wall surface of the first cavity 134 is a concave curved surface structure. In another specific embodiment, the inner wall surface of the first cavity 134 is a planar structure. The inner diameter of the end of the second cavity 135 connected to the first cavity 134 is equal to the inner diameter of the end of the second cavity 135 connected to the first cavity 134. Among them, the central axis of the air outlet hole 132 coincides with the central axis of the atomizer 1.

[0055] In a specific embodiment, there are two lower liquid holes 131 and they are symmetrically arranged on both sides of the air outlet hole 132, or they can be asymmetrically arranged on both sides of the air outlet hole 132. Specifically, the number and shape of the lower liquid holes 131 can be set according to actual conditions.

[0056] The atomizer core 16 is accommodated in the installation space formed by the upper seat body 121 and the lower seat body 141. A lower liquid channel 136 is formed between the side wall of the atomizer core 16 and the inner wall of the installation space. The two ends of the lower liquid channel 136 are respectively connected to the two lower liquid holes 131. The liquid absorption surface 167 of the atomizer core 16 is connected to the lower liquid channel 136, so that the matrix to be atomized in the lower liquid channel 136 can be transmitted to the atomizing surface 166 of the atomizer core 16 through the atomizing surface 166, and then the matrix to be atomized is atomized through the atomizing surface 166 to form an aerosol.

[0057] The atomizing core 16 only covers the air outlet hole 132, so that the aerosol formed by the atomizing core 16 atomizing the substrate to be atomized can be transmitted to the air outlet channel 113 through the air outlet hole 132. The atomizing core 16 includes a porous substrate 161 and a heating element 162. Among them, the surface of the porous substrate 161 close to the air outlet channel 113 serves as an atomizing surface 166, and the surface of the porous substrate 161 away from the air outlet channel 113 serves as a liquid absorption surface 167. Among them, the atomizing surface 166 is opposite to the air outlet channel 113 and is arranged at a distance.

[0058] The heating element 162 may be a heating film or a heating wire. The porous matrix 161 is made of porous ceramic.

[0059] In a specific embodiment, a second sealing member 192 is provided at the connection between the atomizer core 16 and the upper seat body 121, and the second sealing member 192 is used to seal the gap formed between the atomizer core 16 and the upper seat body 121. The material of the second sealing member 192 is silicone.

[0060] The mounting seat 12 is provided with a first air inlet 124 and a second air inlet 126. The first air inlet 124 and the second air inlet 126 are used to transmit the gas outside the mounting seat 12 to the atomizing chamber 133, so as to adjust the airflow transmission mode of the aerosol delivered to the air outlet channel 113. Specifically, the gas outside the mounting seat 12 enters the atomizing chamber 133 through the first air inlet 124 and the second air inlet 126 to form a spirally ascending airflow, and then the aerosol in the atomizing chamber 133 is carried in the spiral ascending process, and can be fully contacted with the inner wall of the atomizing chamber 133 and the air outlet channel 113, so as to extend the transmission path of the aerosol, so that the large droplets in the aerosol are more attached to the inner wall of the atomizing chamber 133 and the air outlet channel 113, thereby reducing the content of large droplets at the outlet of the atomizing chamber 133.

[0061] Specifically, the first air inlet 124 and the second air inlet 126 are arranged on the upper seat 121. Specifically, the first air inlet 124 and the second air inlet 126 are arranged on the annular side wall 122 of the upper seat 121 that does not belong to the lower liquid hole 131. The first air inlet 124 and the second air inlet 126 are arranged asymmetrically; the gas enters the atomizing chamber 133 from the first air inlet 124 and the second air inlet 126 to form two air flows, and the two air flows form a spiral rising air flow in the atomizing chamber 133, so that the aerosol carried by the air flow is fully in contact with the inner wall of the air outlet channel 113.

[0062] In an optional embodiment, the air intake direction of the first air intake portion 124 and the air intake direction of the second air intake portion 126 are parallel to each other, and are parallel to the atomization surface 166 of the atomization core 16. In other words, the air intake direction of the first air intake portion 124 can be arranged relative to the air intake direction of the second air intake portion 126, so that the air intake airflow of the first air intake portion 124 and the air intake airflow of the second air intake portion 126 have a deviation in direction, which is conducive to the airflow forming a spiral upward airflow in the atomization chamber 133. In another optional embodiment, the air intake direction of the first air intake portion 124 and the air intake direction of the second air intake portion 126 may not be parallel to each other.

[0063] In a specific embodiment, the first air inlet portion 124 includes a first air inlet hole 125, and the second air inlet portion 126 includes a second air inlet hole 127. The first air inlet hole 125 and the second air inlet hole 127 are arranged on two opposite surfaces of the mounting base 12, and the inner wall surface of the first air inlet hole 125 on one side away from the air outlet channel 113 and the inner wall surface of the second air inlet hole 127 on one side away from the air outlet channel 113 are flush with the atomization surface 166 of the atomization core 16.

[0064] The first air inlet hole 125 and the second air inlet hole 127 are arranged asymmetrically. Specifically, the first air inlet hole 125 and the second air inlet hole 127 are arranged non-axisymmetrically.

[0065] In an optional embodiment, the first air inlet 125 and the second air inlet 127 are asymmetrically arranged on the mounting base 12. In a specific embodiment, the first air inlet 125 and the second air inlet 127 are asymmetrically arranged in the direction of the central axis of the atomizer 1. In another specific embodiment, see Figure 8 , Figure 8 It is a cross-sectional view of another embodiment of the atomizer provided by the present invention. The positions of the first air inlet 125 and the second air inlet 127 in a direction perpendicular to the central axis of the atomizer 1 are asymmetrical.

[0066] In another optional embodiment, the sizes of the first air inlet hole 125 and the second air inlet hole 127 are set asymmetrically. In a specific embodiment, the heights of the first air inlet hole 125 and the second air inlet hole 127 in the direction of the central axis of the atomizer 1 are inconsistent. In another specific embodiment, 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 inconsistent.

[0067] In other optional embodiments, the positions of the first air inlet 125 and the second air inlet 127 on the mounting base 12 are asymmetrical, and the sizes of the first air inlet 125 and the second air inlet 127 can also be asymmetrically arranged. In a specific embodiment, the positions of the first air inlet 125 and the second air inlet 127 in the direction of the central axis of the atomizer 1 are asymmetrically arranged, or the positions of the first air inlet 125 and the second air inlet 127 in the direction perpendicular to the central axis of the atomizer 1 are asymmetrical, and the heights of the first air inlet 125 and the second air inlet 127 in the direction of the central axis of the atomizer 1 are inconsistent, or the widths of the first air inlet 125 and the second air inlet 127 in the direction perpendicular to the central axis of the atomizer 1 are inconsistent.

[0068] In one specific embodiment, see Figure 9(a) to Figure 9(c)9(a) is a fitting schematic diagram of an embodiment of the airflow state in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; FIG. 9(b) is a fitting schematic 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 diagram showing the relationship between the passage rate of large droplets in the atomizer provided in FIG. 9(b) and the size of the first air inlet hole and / or the second air inlet hole. When the heights of the first air inlet 125 and the second air inlet 127 in the direction of the central axis of the atomizer 1 are inconsistent, or when the widths of the first air inlet 125 and the second air inlet 127 in the direction perpendicular to the central axis of the atomizer 1 are inconsistent, the air inlet areas of the first air inlet 125 and the second air inlet 127 are inconsistent, and there is a difference between the air flow rate of the airflow entering the atomizing chamber 133 through the first air inlet 125 and the air flow rate of the airflow entering the atomizing chamber 133 through the second air inlet 127, so that the two airflows entering the atomizing chamber 133 through the first air inlet 125 and the second air inlet 127 are more likely to form a spiral rising airflow, and then closely contact with the inner wall of the atomizing chamber 133, so that the large 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 during the spiral rising process, thereby reducing the passing rate of the large droplets in the aerosol. Wherein, the particle size of the large droplets is 10-170um.

[0069] In another specific embodiment, see Figure 10(a) to Figure 10(c) , FIG. 10( a ) is a schematic diagram of a fitting of an embodiment of the airflow state in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; FIG. 10( b ) is a schematic diagram of a fitting of another embodiment of the aerosol state in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention;

[0070] Fig. 10(c) is a graph showing the relationship between the passing rate of large droplets in the atomizer and the size of the first air inlet hole and / or the second air inlet hole provided in Fig. 10(b). When the first air inlet hole 125 and the second air inlet hole 127 are arranged opposite to each other and the central axis coincides, 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, the sizes of the first air inlet hole 125 and the second air inlet hole 127 are inconsistent. There is a difference between the air flow rate entering the atomizing chamber 133 through the first air inlet 125 and the air flow rate entering the atomizing chamber 133 through the second air inlet 127, so that the two air flows entering the atomizing chamber 133 through the first air inlet 125 and the second air inlet 127 are more likely to form a spiral rising air flow, and then closely contact the inner wall of the atomizing chamber 133, so that the large 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 during the spiral rising process, thereby reducing the passing rate of the large droplets in the aerosol. The particle size of the large droplets is 10-170um.

[0071] In another specific embodiment, see Fig.11 , Fig.11 1 is a graph showing the relationship between the passing rate of large droplets and the size of the first air inlet hole and / or the second air inlet hole in another embodiment of the atomizer provided by the present invention. When the heights of the first air inlet hole 125 and the second air inlet hole 127 in the direction of the central axis of the atomizer 1 are inconsistent, and 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 non-axisymmetric. The airflow direction entering the atomizing chamber 133 through the first air inlet 125 and the airflow direction entering the atomizing chamber 133 through the second air inlet 127 are both rotated around the central axis direction of the atomizer 1, so that the two airflows entering the atomizing chamber 133 through the first air inlet 125 and the second air inlet 127 are more likely to form a spiral rising airflow, and then closely contact the inner wall of the atomizing chamber 133, so that the large 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 during the spiral rising process, thereby reducing the passing rate of the large droplets in the aerosol. The particle size of the large droplets is 10-170um.

[0072] In a preferred embodiment, the first air inlet 125 and / or the second air inlet 127 are inclined to the inner wall parallel to the central axis of the atomizer 1, and the inclination direction of the inner wall is consistent. In a specific embodiment, the inner wall surface of the first air inlet 125 and / or the second air inlet 127 is inclined to the side of the outlet channel 113; wherein the distance between the end of the inner wall surface close to the atomizing chamber 133 and the plane where the atomizing surface 166 is located is less than the distance between the end of the inner wall surface away from the atomizing chamber 133 and the plane where the atomizing surface 166 is located. In a preferred embodiment, the shape of the first air inlet 125 and / or the second air inlet 127 is a rectangle, and the height of the side of the rectangle perpendicular to the atomizing surface 166 is not greater than the width of the side of the rectangle parallel to the atomizing surface 166. That is, the length of the side of the rectangle parallel to the central axis of the atomizer 1 is not greater than the length of the side of the rectangle perpendicular to the central axis of the atomizer 1. The shapes of the first air inlet 125 and the second air inlet 127 may also be other shapes, as long as it is convenient for the gas entering the atomizing chamber 133 to form a spiral upward airflow in the atomizing chamber 133. The shapes and sizes of the first air inlet 125 and the second air inlet 127 are not limited.

[0073] In an optional embodiment, the first air inlet 124 and the second air inlet 126 are arranged at positions that are non-axisymmetric. In a preferred embodiment, the first air inlet 124 and the second air inlet 126 can be arranged at positions that are centrally symmetrical, so that external gas can enter the atomizing chamber 133 through the first air inlet 124 and the second air inlet 126 to form a spirally ascending airflow. In a specific embodiment, the position of the first air inlet 125 and the position of the second air inlet 127 can be at least partially misaligned. In a specific embodiment, the central axis of the first air inlet 125 can coincide with the central axis of the second air inlet 127 and be parallel to the atomizing surface 166.

The shapes of the first air inlet 125 and the second air inlet 127 may be the same or different. In another optional embodiment, the positions of the first air inlet 125 and the second air inlet 127 may be offset, and the first air inlet 125 and the second air inlet 127 may be at least partially offset.

[0074] In another optional embodiment, the total air inlet area of ​​the first air inlet portion 124 is inconsistent with the total air inlet area of ​​the second air inlet portion 126. Specifically, the number of the first air inlet holes 125 may be one or more. The number of the second air inlet holes 127 may be one or more. When the air inlet area of ​​a first air inlet hole 125 is equal to the air inlet area of ​​a second air inlet hole 127, the number of the first air inlet holes 125 may be different from the number of the second air inlet holes 127, so that there may be a difference between the flow rate of the airflow entering the atomizing chamber 133 through the first air inlet portion 124 and the flow rate of the airflow entering the atomizing chamber 133 through the second air inlet portion 126, which is conducive to forming a spiral upward airflow in the atomizing chamber 133.

[0075] In a preferred embodiment, the width of the first air inlet hole 125 and / or the second air inlet hole 127 is equal to the distribution width of the heating element 162.

Specifically, the upper seat body 121 can be snap-fitted with the lower seat body 141. A third seal 193 is arranged between the upper seat body 121 and the lower seat body 141, and the third seal 193 is installed on a side of the lower seat body 141 close to the upper seat body 121.

[0077] An air inlet 148 is provided on the end cover 18 , and an end of the air inlet channel 149 away from the first air inlet portion 124 or the second air inlet portion 126 serves as the air inlet 148 . External atmosphere enters the air inlet channel 149 through the air inlet 148 , and is then transmitted to the atomization chamber 133 through the first air inlet portion 124 and the second air inlet portion 126 .
