Description

Technical Field

[0001] The present invention relates to the technical field of atomization devices, and in particular to an atomizer and an electronic atomization device thereof. Background Art

[0002] In the prior art, electronic atomization devices primarily consist of an atomizer and a power supply assembly. The atomizer generally includes a liquid reservoir for storing atomizable medium and an atomizer assembly for heating and atomizing the atomizable medium to form an aerosol for the user. The power supply assembly provides energy to the atomizer. Most atomizers are arranged with the atomizing surface facing downward and the bottom facing the air intake. This creates a large amount of eddy currents within the atomizer chamber, allowing condensed smoke oil and oil droplets to remain within the chamber. This accumulation over time can eventually lead to leakage. Summary of the Invention

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The terms "first", "second" and "third" in the present invention are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" and "third" may explicitly or implicitly include at least one feature. In the description of the present invention, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications also change accordingly. The terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products or devices.

[0046] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] To address the issue of bottom-direct air intake affecting atomization volume, the inventors of this application developed an atomizer with an upward-facing atomizing surface, but the design of its air intake method posed a new challenge.

[0048] See also Figure 1(a) to Figure 1(d)Figure 1(a) is a schematic diagram of the aerosol state fitting when the atomizer with the atomizing surface facing upward is in a single airway on both sides of the atomizing chamber; Figure 1(b) is a schematic diagram of the airflow state fitting of the atomizer in Figure 1(a); Figure 1(c) is a schematic diagram of the aerosol volume fraction fitting of the atomizer in Figure 1(a); Figure 1(d) is a schematic diagram of the tracking of 10um large droplets in the atomizing chamber and the air outlet channel of the atomizer in Figure 1(a). If a symmetrical counter-flow air intake method is designed, a "stagnation zone" is easily formed in the central area of the heating element, making it difficult for the aerosol to be carried away. At the same time, the vortex near the air inlet will cause the fried oil droplets to be brought into the central area of the vortex, causing the droplets to adhere to the wall of the atomizing chamber; if an asymmetric air intake method is designed, the droplets will be blown directly to the wall opposite to the air inlet and cannot reach the outside world with the main airflow.

[0049] At the same time, the aerosol is affected by the vortex in the airway and condenses on the wall, resulting in the formation of condensate.

[0050] The inventors of this application have continuously improved and optimized the above technical means and proposed the following embodiments:

[0051] See also Figure 2 、 Figure 3 and Figure 4 , Figure 2 This is a schematic structural diagram of an embodiment of an electronic atomization device provided by the present invention; Figure 3 is a cross-sectional view of an embodiment of an atomizer provided by the present invention; Figure 4 It is a cross-sectional view of the atomizer provided by the present invention from another angle.

When the atomizer 1 needs to be replaced, the atomizer 1 can be disassembled and a new atomizer 1 can be installed on the host 2 to achieve the reuse of the host 2.

[0052] In another optional embodiment, the provided electronic atomization device 100 includes a housing 11, a mounting base 12, an atomizer core 16, and a power supply assembly 21.

Among them, the liquid storage chamber 111 is arranged at the end of the shell 11 close to the suction nozzle assembly 17, and the mounting chamber 112 is arranged at the end of the shell 11 close to the end cover 18. The liquid storage chamber 111 is adjacent to and connected to the mounting chamber 112. The air outlet channel 113 is arranged in the shell 11 and is connected to the end of the shell 11 connected to the suction nozzle assembly 17. The air outlet channel 113 extends along the liquid storage chamber 111 to the end close to the mounting chamber 112, and the air outlet channel 113 extends to the mounting chamber 112 from the end of the liquid storage chamber 111 and is connected to the mounting chamber 112. That is, the air outlet channel 113 connects the nozzle assembly 17 to the mounting chamber 112. In an optional embodiment, the liquid storage chamber 111 is disposed around the air outlet channel 113, with the central axis of the air outlet channel 113 being parallel to the central axis of the atomizer 1. In a preferred embodiment, the central axis of the air outlet channel 113 coincides with the central axis of the atomizer 1. The liquid storage chamber 111 is used to store the substrate to be atomized. The air outlet channel 113 connects the mounting chamber 112 to the nozzle assembly 17.

[0056] Further reading Figure 6 and Figure 7 , Figure 6 This is a structural diagram of an embodiment of the upper seat of the atomizer provided by the present invention; Figure 7This is a structural schematic diagram of the upper body of the atomizer provided by the present invention from another angle. The mounting seat 12 is at least partially accommodated in the mounting cavity 112. In a specific embodiment, the mounting seat 12 is completely accommodated in the mounting cavity 112, and the outer wall of the mounting seat 12 is tightly fitted with the inner wall of the mounting cavity 112. One end of the mounting seat 12 and the inner wall of the shell 11 form the above-mentioned liquid storage cavity 111. One end of the mounting seat 12 has an air outlet 132 and a lower liquid hole 131. The air outlet 132 and the lower liquid hole 131 are arranged at intervals. The air outlet 132 is arranged opposite to and connected to the air outlet channel 113. The part of the air outlet 132 located between the air outlet channel 113 and the atomizer core 16 cooperates with the atomizer core 16 to form the atomizer cavity 133. The main air inlet and the secondary air inlet 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 seat 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 for accommodating the atomizer core 16.

[0057] 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 spaced apart. In a specific embodiment, part of the annular side wall 122 and the outer wall of the air outlet hole 132 form 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 portion of the air outlet hole 132 where the air outlet channel 113 is installed is larger than the inner diameter of the end portion of the air outlet hole 132 that forms the atomizing chamber 133 and is close to the air outlet channel 113. In an optional embodiment, the end portion of the air outlet channel 113 can be in close contact with 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. 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 prevent 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 prevent 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. 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 132 is connected 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. That is to say, 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 connected to 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, the inner diameter of the end of the first cavity 134 connecting 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 passage 113. In one embodiment, the inner wall of the second cavity 135 has a convex curved surface. In another embodiment, the inner wall of the second cavity 135 has a flat surface.In a preferred embodiment, an air guide groove 136 is formed on the inner wall of the first cavity 134. The air guide groove 136 extends from the end of the first cavity 134 connecting to the second cavity 135 to the end of the first cavity 134 away from the second cavity 135. The inner diameter of the end of the second cavity 135 connecting to the first cavity 134 is equal to the inner diameter of the end of the second cavity 135 connecting to the first cavity 134. The central axis of the air outlet 132 coincides with the central axis of the atomizer 1.

[0058] In one embodiment, there are two lower liquid holes 131 symmetrically disposed on both sides of the air outlet 132, or asymmetrically disposed on both sides of the air outlet 132. Specifically, the number and shape of the lower liquid holes 131 can be set according to actual conditions.

[0059] See also Figure 8 , Figure 8 It is a structural schematic diagram of an embodiment of the atomizer core in the atomizer provided by the present invention. The atomizer core 16 is arranged in the installation space formed by the upper seat 121 and the lower seat 141. The atomizer core 16 covers the lower liquid hole 131 and the air outlet 132, so that the lower liquid hole 131 can conduct the matrix to be atomized in the liquid storage chamber 111 to the atomizer core 16. At the same time, the aerosol formed by heating and atomizing the atomizer core 16 can be transmitted to the air outlet channel 113 through the air outlet 132. The atomizer core 16 includes a porous matrix 161 and a heating element 162. Among them, the porous matrix 161 includes an integrally formed liquid guide portion 163 and a protrusion 165. The heating element 162 is provided on the surface of the protrusion 165 on one side away from the liquid guide portion 163. The raised portion 165 is disposed on a side surface of the liquid-guiding portion 163 that is adjacent to the air outlet channel 113. The surface of the raised portion 165 that is distal to the liquid-guiding portion 163 serves as an atomizing surface 166, and the surface of the liquid-guiding portion 163 that contacts the lower liquid hole 131 serves as a liquid suction surface 167. The atomizing surface 166 is spaced apart from and opposite to the air outlet channel 113. That is, the atomizing surface 166 of the atomizer core 16 and at least a portion of the liquid suction surface 167 of the atomizer core 16 are located on the same side and are disposed on the side of the atomizer core 16 that is adjacent to the air outlet channel 113. In another specific embodiment, to increase the liquid suction surface 167, a connecting hole 164 is disposed within the liquid-guiding portion 163. The connecting hole 164 is connected to the lower liquid hole 131 and extends from one side surface of the liquid-guiding portion 163 to the opposite surface. In other words, the two ends of the connecting hole 164 are connected to the lower liquid holes 131 disposed on either side of the air outlet channel 132. The heating element 162 may be a heating film or a heating wire. The porous matrix 161 is made of porous ceramic.

[0060] In one embodiment, a second sealing member 192 is provided at the connection between the atomizer core 16 and the upper body 121. The second sealing member 192 is used to seal the gap formed between the atomizer core 16 and the upper body 121. The material of the second sealing member 192 is silicone.

[0061] See also Figures 9 to 12 , Figure 9 This is a schematic diagram of the state fitting of the aerosol in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; Figure 10 It is a schematic diagram of the airflow state fitting in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; Figure 11 Schematic diagram of the aerosol volume fraction fitting in the atomizing chamber and the air outlet channel of the atomizer provided by the present invention; Figure 12 It is a schematic diagram of tracking large droplets of 10um particle size in the atomizer provided by the present invention. A main air inlet 124 and a secondary air inlet 127 are provided on the mounting base 12. The main air inlet 124 and the secondary air inlet 127 are used to transmit the gas outside the mounting base 12 to the atomizing chamber 133 to adjust the air flow of the aerosol delivered to the air outlet channel 113, avoid the air flow of the aerosol from contacting the inner wall surface of the air outlet channel 113, and thus reduce the condensate and increase the atomization amount. Specifically, when the air flow of the aerosol enters the air outlet channel 113 from the atomizing chamber 133, the secondary air inlet 127 controls the externally input gas to form a barrier layer on the inner wall surface of the air outlet channel 113, so as to reduce the diameter of the air column formed by the air flow of the aerosol.

[0062] See also Figure 4 and Figure 6 Specifically, the main air inlet 124 and the secondary air inlet 127 are arranged on the upper base 121. Specifically, the main air inlet 124 and the secondary air inlet 127 are arranged on the annular side wall 122 of the upper base 121 that does not belong to the lower liquid hole 131. The main air inlet 124 is arranged adjacent to the atomizing surface 166. The main air inlet 124 is used to allow external gas to enter the atomizing chamber 133 and adjust the gas-carrying aerosol to form a mainstream air column with the central axis of the air outlet channel 113 as the center. The secondary air inlet 127 is arranged on the side of the main air inlet 124 away from the atomizing surface 166. The secondary air inlet 127 is used to allow external gas to enter the atomizing chamber 133 and adjust the gas to form a barrier layer on the inner wall of the air outlet channel 113. The barrier layer is an air film. The inner diameter of the outlet channel 113 is constant, and the gas transmitted by the secondary air inlet 127 forms a barrier layer on the inner wall of the outlet channel 113, which can reduce the diameter of the mainstream air column to prevent the aerosol from contacting the inner wall of the outlet channel 113, thereby increasing the atomization amount.

[0063] In one embodiment, the air intake direction of the primary air intake portion 124 and the air intake direction of the secondary air intake portion 127 are parallel to each other and are located on the same longitudinal plane. The air intake direction of the primary air intake portion 124 and the air intake direction of the secondary air intake portion 127 are parallel to the atomizing surface 166. In another embodiment, the air intake direction of the primary air intake portion 124 and the air intake direction of the secondary air intake portion 127 may also be arranged in a non-parallel manner.

[0064] See also Figure 4 Specifically, the main air inlet portion 124 includes at least a first through hole 125 and a second through hole 126, which are respectively arranged on two opposing side walls of the mounting base 12, that is, on two opposing portions of the annular side wall 122. The shape and size of the first through hole 125 and the second through hole 126 are not limited. In one embodiment, the shape of the first through hole 125 and / or the second through hole 126 is rectangular, and the length H1 of the side of the rectangle parallel to the central axis of the atomizer 1 is no greater than the length L1 of the side of the rectangle perpendicular to the central axis of the atomizer 1. The length of the side of the first through hole 125 or the second through hole 126 perpendicular to the central axis of the atomizer 1 is equal to the width of the first through hole 125 and / or the second through hole 126. In a preferred embodiment, the central axis of the first through hole 125 and / or the second through hole 126 is coplanar with the atomizing surface 166. The airflow entering the atomizing chamber 133 through the first through hole 125 and / or the second through hole 126 is used to carry the aerosol into the air outlet channel 113 and form a vortex zone in the atomizing chamber 133.

[0065] See also Figure 13(a) to Figure 13(d) Figure 13(a) is a schematic diagram of the structure when the width ratio of the first through hole to the heating element in the atomizer provided by the present invention is 1:2; Figure 13(b) is a schematic diagram of the structure when the width ratio of the first through hole to the heating element in the atomizer provided by the present invention is 1:1; Figure 13(c) is a schematic diagram of the airflow state fitting when the width ratio of the first through hole to the heating element in the atomizer provided by the present invention is 1:2; Figure 13(d) is a schematic diagram of the airflow state fitting when the width ratio of the first through hole to the heating element in the atomizer provided by the present invention is 1:1. In an optional embodiment, the width L1 of the first through hole 125 and / or the second through hole 126 is equal to the distribution width W1 of the heating element 162. The width direction of the first through hole 125 and the second through hole 126 is a direction perpendicular to the central axis of the atomizer 1. The width direction of the heating element 162 is the direction of the line connecting the two lower liquid holes 131. In an alternative embodiment, when the first through hole 125 and the second through hole 126 are rectangular in shape, the length of the side of the first through hole 125 and the second through hole 126 perpendicular to the central axis of the atomizer 1 is equal to the width of the heating element 162. In another alternative embodiment, the first through hole 125 and the second through hole 126 are circular in shape, and the diameter of the first through hole 125 and the second through hole 126 is equal to the width of the heating element 162.

[0066] When the width of the first through hole 125 and the second through hole 126 is equal to the distribution width of the heating element 162, the gas transmitted into the atomization chamber 133 by the first through hole 125 and the second through hole 126 can carry more aerosol generated by the atomization surface 166 away from the atomization surface 166. The width of the first through hole 125 and the second through hole 126 being equal to the distribution width of the heating element 162 can expand the coverage area of the gas delivered to the atomization chamber 133 and increase the force exerted by the gas when entering the atomization chamber 133, thereby concentrating the aerosol in the atomization chamber 133 on the central axis of the air outlet channel 113, reducing the cross-section of the air column formed by the aerosol, and preventing the aerosol from diffusing in the air outlet channel 113. The air intake from the first through hole 125 and the second through hole 126 can cover the entire surface of the aerosol generated by the heating element 162. Sufficient air intake can carry the large-sized aerosol droplets produced by the atomizing surface 166 to the air outlet channel 113 and into the user's mouth, preventing the large aerosol droplets from falling back to the atomizing surface 166 due to gravity and forming condensate. The large droplets have a particle size of 10-170 μm.

[0067] In a specific embodiment, the position of the first through hole 125 and the position of the second through hole 126 can be set relative to each other. In a specific embodiment, the central axis of the first through hole 125 and the central axis of the second through hole 126 coincide and are parallel to the atomizing surface 166. The position of the first through hole 125 and the position of the second through hole 126 can also be staggered on the annular side wall 122 of the upper seat 121. In a specific embodiment, the position of the first through hole 125 can be longitudinally staggered or laterally staggered with the position of the second through hole 126. The structure of the first through hole 125 and the structure of the second through hole 126 can be the same or different. The shapes of the first through hole 125 and the second through hole 126 can be the same or different. In another optional embodiment, the positions of the first through hole 125 and the second through hole 126 can be staggered, and the first through hole 125 and the second through hole 126 are at least partially set relative to each other. When the positions of the first through hole 125 and the second through hole 126 are symmetrical, the stagnation area formed near the atomizing surface 166 is on the central axis of the atomizer 1; when the positions of the first through hole 125 and the second through hole 126 are asymmetrical, the stagnation area formed near the atomizing surface 166 deviates from the central axis of the atomizer 1.

[0068] The secondary air inlet 127 includes at least a third through hole 128 and a fourth through hole 129, which are disposed on opposite sidewalls of the mounting base 12. The third through hole 128 and / or the fourth through hole 129 are disposed on the upper base 121, on a side of the first through hole 125 and the second through hole 126 away from the lower base 141. In one embodiment, the third through hole 128 and / or the fourth through hole 129 are disposed on the portion of the sidewall of the outlet 132 where the outlet channel 113 is mounted. The end surface of the outlet channel 113 serves as a portion of the sidewall of the third through hole 128 and the fourth through hole 129. The ends of the third through hole 128 and the fourth through hole 129, which are adjacent to the inner wall of the outlet 132, are flush with the inner wall of the outlet channel 113 and the inner wall of the first cavity 134, thus avoiding any blind spots between the third through hole 128 and the fourth through hole 129 and the end surface of the outlet channel 113. The airflow entering the atomizing chamber 133 through the third through hole 128 and the fourth through hole 129 is used to disperse the eddy current region retained in the atomizing chamber 133, so that the aerosol in the eddy current region enters the outlet passage 113. The ports of the third through hole 128 and the fourth through hole 129 close to the atomizing chamber 133 are flush with the inner wall surface of the outlet passage 113, so that the gas entering through the third through hole 128 and the fourth through hole 129 can enter the outlet passage 113 more smoothly, and form a barrier layer on the inner wall surface of the outlet passage 113 to prevent the aerosol from contacting the inner wall surface of the outlet passage 113.

[0069] In one specific embodiment, the central axis of the third through hole 128 and / or the fourth through hole 129 is parallel to the plane of the atomizing surface 166. In another specific embodiment, the distance between the end of the third through hole 128 and / or the fourth through hole 129 close to the atomizing chamber 133 and the plane of the atomizing surface 166 is greater than the distance between the end of the third through hole 128 and / or the fourth through hole 129 away from the atomizing chamber 133 and the plane of the atomizing surface 166. In another optional embodiment, the distance between the end of the third through hole 128 and / or the fourth through hole 129 close to the atomizing chamber 133 and the plane of the atomizing surface 166 is less than the distance between the end of the third through hole 128 and / or the fourth through hole 129 away from the atomizing chamber 133 and the plane of the atomizing surface 166.

[0070] In a specific embodiment, the position of the third through hole 128 and the position of the fourth through hole 129 can be set relative to each other. In a specific embodiment, the central axis of the third through hole 128 and the central axis of the fourth through hole 129 coincide and are parallel to the atomizing surface 166. The position of the third through hole 128 and the position of the fourth through hole 129 can also be staggered on the annular side wall 122 of the upper seat 121. In a specific embodiment, the position of the third through hole 128 can be longitudinally staggered with the position of the fourth through hole 129, or can be laterally staggered. The structure of the third through hole 128 and the structure of the fourth through hole 129 can be the same or different. The shapes of the third through hole 128 and the fourth through hole 129 can be the same or different. In another optional embodiment, the positions of the third through hole 128 and the fourth through hole 129 can be staggered, and at least parts of the third through hole 128 and the fourth through hole 129 are set relative to each other. In a preferred embodiment, the third through hole 128 and / or the fourth through hole 129 is rectangular in shape, and 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 .

[0071] The third through hole 128 and the first through hole 125, and the fourth through hole 129 and the second through hole 126 can be arranged opposite to each other or staggered. In one embodiment, the third through hole 128 and the first through hole 125, and the fourth through hole 129 and the second through hole 126 can be staggered along the central axis of the atomizer 1.

[0072] The height direction of the through hole is the direction extending along the central axis of the atomizer 1. When the height of the first through hole 125 and / or the second through hole 126 is small, the air flow velocity of the first through hole 125 and / or the second through hole 126 is small, and a larger stagnant area will be formed near the atomizing surface 166, and the aerosol in the stagnant area will be difficult to be brought to the outside. When the height of the third through hole 128 and / or the fourth through hole 129 is large, the vortex area formed by the gas transmitted through the first through hole 125 and / or the second through hole 126 and the inner wall of the second cavity 135 becomes smaller, so that the passing rate of the aerosol in the atomizing cavity 133 is increased. In a specific embodiment, please refer to Figure 14 and Figure 15 , Figure 14 3 is a schematic diagram of the flow velocity contours of the aerosol in the atomizing chamber and the air outlet channel when the height of the third through hole provided by the present invention is 0.3 mm; Figure 15133 。 This is a schematic diagram of the flow velocity contours of the aerosol in the atomizing chamber and the air outlet channel when the height of the third through hole provided by the present invention is 0.6 mm. When the height of the first through hole 125 and / or the second through hole 126 is 0.3 mm, and the height of the third through hole 128 and / or the fourth through hole 129 increases from 0.3 mm to 0.6 mm, the height of the third through hole 128 and / or the fourth through hole 129 increases, and the gas in the third through hole 128 and / or the fourth through hole 129 impacts the vortex area formed by the first through hole 125 and / or the second through hole 126 and the inner wall of the atomizing chamber 133. The vortex area formed by the first through hole 125 and / or the second through hole 126 on the inner wall of the atomizing chamber 133 is reduced. Because the gas entering the third through hole 128 and / or the fourth through hole 129 exerts a certain pressure on the gas entering the first through hole 125 and the second through hole 126, the aerosol carried by the gas entering the first through hole 125 and / or the second through hole 126 is squeezed to a certain extent, causing the stagnant area formed near the atomization surface 166 to slightly increase, thereby affecting the aerosol passage rate. Therefore, the heights of the first through hole 125, the second through hole 126, the third through hole 128, and the fourth through hole 129 can be designed based on the aerosol passage rate.

[0073] A liquid collecting trough 137 is provided on the outer wall surface of the annular side wall 122 . The liquid collecting trough 137 is used to collect liquid leaked from the primary air inlet portion 124 and the secondary air inlet portion 127 , and is also used to collect liquid leaked from the air inlet space 151 .

The lower seat body 141 is arranged on the side of the upper seat body 121 away from the air outlet channel 113 and is fixedly connected to the upper seat body 121.

In a specific embodiment, the lower seat body 141 includes a base plate 142 and a support assembly 145 arranged on a surface of the base plate 142 near the atomizing core 16. In a specific embodiment, the support assembly 145 includes a first support arm 146 and a second support arm 147, and the first support arm 146 and the second support arm 147 are arranged on the base plate 142 opposite to each other and spaced apart. A boss 148 is provided on the surface opposite to the first support arm 146 and the second support arm 147. The boss 148 is used to support the atomizing core 16, and the boss 148 is in contact with the side of the atomizing core 16 away from the atomizing surface 166. The boss 148 is provided with a first capillary groove 149, which is used to receive liquid leaking from the atomizer core 16. The base plate 142 is provided with an air inlet hole 144. An air inlet space 151 is formed between the base plate 142 and the atomizer core 16. An air inlet channel 150 is formed between the annular sidewall 122 and the housing 11. One end of the air inlet channel 150 communicates with the air inlet space 151, and the other end communicates with the primary air inlet 124 and the secondary air inlet 127.
