[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Please refer to Figures 1 to 3 This utility model provides an atomizer 100, including a main body 10 and a circuit assembly 20. The first direction Z is the height direction of the atomizer 100, and the second direction X is the width or thickness direction of the atomizer 100, which is not limited.

[0023] Please refer to Figure 1 and Figure 2 The main body 10 has a microphone air passage 111, a suction air passage 112, and a liquid storage chamber 113. The microphone air passage 111 and the suction air passage 112 are located on both sides of the liquid storage chamber 113, and both extend along a first direction Z. The main body 10 also has a first air inlet 114, which communicates with the microphone air passage 111. The main body 10 also includes a receiving cavity 115, which communicates with the microphone air passage 111. The receiving cavity 115 has a connecting hole 116, which connects the receiving cavity 115 and the microphone air passage 111. The cross-sectional shape of the first air inlet 114 and the connecting hole 116 can be circular, rectangular, elliptical, etc., without limitation. The main body 10 can be made of a material with high structural strength, specifically metal materials, high-strength plastics, ceramics, etc. Metal materials include aluminum, aluminum alloys, magnesium alloys, iron, and iron alloys, without limitation. Optionally, the opening of the receiving cavity 115 is located on the side of the receiving cavity 115 opposite to the liquid storage cavity 113, and the circuit assembly 20 is received in the receiving cavity 115 through the opening.

[0024] Please refer to Figure 1 and Figure 2The circuit assembly 20 is housed within the receiving cavity 115. The circuit assembly 20 includes a substrate 21 and a microphone 22. The microphone 22 is disposed on one side of the substrate 21 in the second direction X. A first air inlet 114 is disposed on the side of the microphone 22 facing the substrate 21 in the second direction X. A microphone air passage 111 is disposed on the side of the microphone 22 facing away from the substrate 21. In the orthographic projection in the first direction Z, the connecting hole 116 and the microphone air passage 111 are staggered, and the first direction Z intersects the second direction X. The connecting hole 116 is disposed on the side of the receiving cavity 115 away from the circuit assembly 20. The circuit assembly 20 also includes electronic components disposed on the substrate 21. These electronic components can be sensors, chips, etc., and are not limited. The microphone 22 can be a silicon microphone, an electret microphone, etc., and is not limited. The microphone 22 is electrically connected to the substrate 21. Optionally, in the orthographic projection in the first direction Z, the connecting hole 116 and the microphone air passage 111 can be arranged alternately or partially overlapped, without limitation. Optionally, the atomizer 100 also includes a first absorbent cotton, which is disposed on the side of the microphone air passage 111 near the connecting hole 116, and the first absorbent cotton is spaced apart from the connecting hole 116. The substrate 21 and the microphone 22 are spaced apart in the second direction X to form a first air inlet 114. The first air inlet 114 communicates with the outside through the opening of the receiving cavity 115. After the gas impacts and activates the microphone 22 through the first air inlet 114, it enters the microphone air passage 111. The independent first air inlet 114 reduces the chance of the microphone 22 coming into contact with high temperature / high humidity gas, thereby extending the service life of the microphone 22.

[0025] Optionally, the atomizer 100 also includes a housing 30 and a battery 40. Both the main body 10 and the battery 40 are housed within the housing 30. The battery 40 is located on the side of the circuit assembly 20 facing away from the atomizing core 50 and is used to heat the atomizing core 50.

[0026] Optionally, the battery 40 can be a cylindrical soft-pack battery, a square soft-pack battery, a cylindrical steel-cased battery, etc., without restriction.

[0027] Optionally, the shell 30 may be made of a material with high structural strength, such as metal, high-strength plastic, ceramic, etc. Metal materials include aluminum, aluminum alloy, magnesium alloy, iron and iron alloy, etc., without limitation.

[0028] This invention avoids trigger delays or malfunctions caused by airflow mixing in traditional shared airway designs by setting an independent microphone airway 111. Furthermore, the microphone airway 111 is staggered with the receiving cavity 115 of the circuit assembly 20. At the same time, the positions of the microphone airway 111, microphone 22, and substrate 21 are defined. When the atomizer 100 is tilted or condensation is generated, the condensation will not flow back to the microphone 22 and substrate 21 and other circuit assemblies 20 through the microphone airway 111 and the connecting hole 116. This significantly extends the service life of the circuit assembly 20 and reduces the failure rate of the circuit assembly 20.

[0029] Please refer to Figure 1 In one embodiment, the main body 10 further includes a snap-fit ​​portion 12, which is housed in a receiving cavity 115. The snap-fit ​​portion 12 is connected and fixed to the side of the microphone 22 facing away from the substrate 21. The snap-fit ​​portion 12 has a first start-up air passage 121, one end of which is connected to a first air inlet 114 and the other end is connected to a connecting hole 116. The first start-up air passage 121 extends along a first direction Z.

[0030] Optionally, the first starting airway 121 extends along the first direction Z, and the dimensions of the first starting airway 121 in the second direction X can be consistent or different, without limitation.

[0031] Optionally, the snap-fit ​​part 12 can be made of metal, high-strength plastic, ceramic, elastic element, etc. Metal materials include aluminum, aluminum alloy, magnesium alloy, iron and iron alloy, etc., and elastic elements include silicone, rubber, etc., without limitation.

[0032] Optionally, the snap-fit ​​portion 12 has a receiving groove on the surface of the substrate 21 in the second direction X, the microphone 22 is received in the receiving groove, and the receiving groove has a first hole 122 on the bottom wall in the second direction X, the first hole 122 is connected to the first start air passage 121.

[0033] Optionally, the first starting airway 121 can be formed by the locking part 12, or by the locking part 12 being enclosed by the side wall and top wall of the receiving cavity, without limitation.

[0034] Optionally, the connection between the snap-fit ​​part 12 and the inner wall of the receiving cavity can be snap-fit, adhesive, screw, weld, magnetic connection, etc., without limitation.

[0035] The first start-up air duct 121 is located on the side of the microphone 22 facing away from the substrate 21. Gas passes sequentially through the first air inlet 114, the microphone 22, the first start-up air duct 121, and the microphone air duct 111 before being discharged to the outside. The independent air duct design ensures that the microphone 22 only receives the target airflow signal, avoiding interference from external vibrations, sound, or temperature changes. Furthermore, this design prevents any condensate that may be generated in the microphone air duct 111 from flowing back to the microphone 22 and the circuit components 20 on the substrate 21, thus preventing malfunctions in the circuit components 20.

[0036] Please refer to Figure 1 In one embodiment, the main body 10 also has a second air inlet 117, which is connected to the suction air passage 112 and is located on the side of the microphone 22 facing away from the substrate 21.

[0037] Optionally, the second air inlet 117 is closer to the microphone airway 111 than the suction airway 112.

[0038] The second air inlet 117, in conjunction with the suction channel, forms an independent airflow path, guiding cool air directly through the atomizer core 50 and preventing high-temperature buildup that could lead to dry burning or a burnt smell. The separate airflow paths for the microphone 22 and the atomizer core 50 prevent high-temperature aerosol from heating the microphone 22 area and causing sensor drift. The high-flow, independent second air inlet 117 reduces the rate of carbon buildup inside the atomizer core 50, decreasing the frequency of cleaning. Furthermore, the separate second air inlet 117 ensures stable airflow within the atomizer core 50, preventing aerosol concentration fluctuations caused by interference from the microphone 22's suction.

[0039] Please refer to Figure 1 In one embodiment, the main body 10 further has a second start-up air passage 118, which is disposed on the side of the microphone 22 facing away from the substrate 21. The second start-up air passage 118 is spaced apart from the first start-up air passage 121 and the receiving cavity 115. The second start-up air passage 118 extends along the first direction Z and is connected to the second air inlet 117.

[0040] Optionally, the second start-up airway 118 is formed by the main body 10 and the housing 30, or the second start-up airway 118 is formed by the main body 10 alone.

[0041] Optionally, the atomizer 100 also includes an adjustment valve, which can be located at the second air inlet 117 and / or the second start-up airway 118, allowing the user to adjust the air intake as needed.

[0042] The spaced-out first and second start-up airways 121 and 118 avoid interference from the inhaled airflow on the microphone 22's detection signal when the microphone 22 and atomizer 50 share an airway, reducing false triggering. The independent airway design ensures that the microphone 22 senses negative pressure only through the first start-up airway 121, while the atomizer 50 obtains stable airflow through the second start-up airway 118, ensuring that their operation does not interfere with each other. After entering through the second air inlet 117, the airflow flows directly to the atomizer 50 through the second start-up airway 118, reducing bend loss and lowering draw resistance.

[0043] Please refer to Figure 1 and Figure 3 In one embodiment, the atomizer 100 further includes an atomizing core 50, which is housed within the main body 10 and has a through hole 51. The main body 10 also has an atomizing airway 13 extending along the second direction X. The through hole 51 surrounds and forms part of the atomizing airway 13. One end of the atomizing airway 13 is connected to the suction airway 112, and the other end of the atomizing airway 13 is connected to the second start-up airway 118.

[0044] Optionally, the atomizing airway 13 includes a first atomizing section 131, a second atomizing section 132, and a third atomizing section 133 connected in sequence. The first atomizing section 131 is connected to the second activation airway 118, and the third atomizing section 133 is connected to the suction airway 112. The second atomizing section 132 is formed by the through hole 51 of the atomizing core 50.

[0045] Optionally, the dimension of the first atomizing section 131 in the first direction Z can gradually decrease along the direction closer to the second atomizing section 132. This ensures the airflow velocity within the second atomizing section 132.

[0046] Optionally, the atomizer 100 also includes a second absorbent cotton, which is disposed at the bottom of the third atomizing section 133 in the first direction Z, for absorbing condensate that may be generated in the suction channel 112 and the atomizing channel 13.

[0047] Optionally, the opening of the liquid storage chamber 113 is connected to the atomizing core 50.

[0048] With this configuration, the through hole 51 of the atomizing core 50 directly constitutes part of the atomizing airway 13, allowing the airflow to enter from the second activation airway 118 and flow in a directional manner along a preset path (second direction X), thus avoiding energy loss caused by the diffusion of airflow around the atomizing core 50 in traditional designs.

[0049] Please refer to Figure 3 In one embodiment, the orthographic projection of the inner circumferential surface of the through hole 51 onto the second direction X is a rectangle.

[0050] Optionally, the orthographic projection of the inner circumferential surface of the atomizer core 50 can be a rectangle, a square, etc., without restriction. The inner circumferential surfaces of the atomizer core 50 can be smoothly transitioned or directly connected, without restriction.

[0051] The square through-hole 51 helps to increase the contact area between the inner wall of the atomizing core 50 and the atomizing medium, thus improving the atomization efficiency of the atomizing medium. At the same time, the square through-hole 51 provides better installation space for the heating element 60.

[0052] Please refer to Figure 3 In one embodiment, the orthographic projection of the outer peripheral surface of the atomizing core 50 in the second direction X is a rectangle.

[0053] Optionally, the orthographic projection of the outer peripheral surface of the atomizer core 50 can be a rectangle, a square, etc., without restriction. The outer peripheral surfaces of the atomizer core 50 can be smoothly transitioned.

[0054] The square atomizing core 50 has similar paths from each outer surface to the heating element 60, resulting in uniform liquid distribution. The outer surface of the square atomizing core 50 does not require a cotton-wrapping structure, avoiding the risk of violent vaporization of the atomizing medium and "spitting" caused by localized overheating at high temperatures. The ceramic substrate of the square atomizing core 50 has high thermal stability, uniformly distributing heat and preventing excessively high local temperatures, thus reducing the risk of spitting.

[0055] Please refer to Figure 1 and Figure 3 In one embodiment, the atomizer 100 further includes a heating element 60, which includes a first heating part and a second heating part arranged at a distance from each other, and the first heating part and the second heating part are disposed on the inner peripheral surface of the through hole 51.

[0056] Optionally, the connection method between the atomizing core 50 and the heating element 60 can be snap-fit, screw-fit, welding, bonding, printing / etching patch molding, pre-embedded sintering, metal connecting ring fixing, etc., without limitation.

[0057] Optionally, the heating element 60 can be made of iron-chromium-aluminum alloy, nickel-chromium alloy, nickel, titanium, stainless steel, etc., without restriction.

[0058] Optionally, the heating element 60 can be multiple annular heating units connected end to end. The first heating part and the second heating part, composed of multiple heating elements, are flat, meaning that multiple heating elements are located on the same side surface and are flush. Optionally, the first heating part and the second heating part can be multiple heating elements connected in parallel by means of snap-fit, screw-fit, riveting, etc. The first heating part and the second heating part can also be an integral component manufactured by a one-piece molding process, which can be stamping or is not limited.

[0059] The first heating element 60 is provided with two heating parts, which helps to improve the atomization efficiency of the atomizing medium and avoids phenomena such as charring of the atomizing medium due to local overheating.

[0060] Please refer to Figure 1 and Figure 3 In one embodiment, the atomizer 100 further includes a connector, which includes a first connecting portion and a second connecting portion spaced apart in the second direction X. The first connecting portion and the second connecting portion are both connected to the first heating portion and the second heating portion. The first connecting portion and the second connecting portion protrude from the surface of the atomizing core 50 facing away from the liquid storage chamber 113.

[0061] Optionally, the connector can be an integral part of the heating element 60, or the connection between the connector and the heating element 60 can be welding, bonding, snap-fitting, screwing, etc., without restriction.

[0062] Optionally, both the first connecting part and the second connecting part are conductive components.

[0063] Optionally, the first connecting part and the second connecting part extend in the first direction Z and are electrically connected to the circuit assembly 20, which simplifies the contact resistance in the connection link, improves the efficiency of current transmission, avoids voltage fluctuations caused by poor contact, thereby stabilizing the heating power of the atomizing core 50 and improving the atomization consistency during use.

[0064] Please refer to Figure 1 In one embodiment, the main body 10 is further provided with an air outlet duct 14, one end of which is connected to the outside, and the other end of which is connected to both the suction duct 112 and the microphone duct 111.

[0065] Optionally, the air outlet duct 14 includes a first section, a second section, and a third section. One end of the first section is connected to the microphone air outlet 111, and the other end is connected to the third section. One end of the second section is connected to the suction air outlet 112, and the other end is connected to the third section. The third section is connected to the outside. Alternatively, the end of the main body 10 away from the circuit assembly 20 has a first air outlet and a second air outlet. The first air outlet connects the air outlet duct 14 and the suction air outlet 112, and the second air outlet connects the microphone air outlet 111 and the air outlet duct 14.

[0066] Optionally, the first segment and the second segment form an angle with the first direction Z. Specifically, the first and second segments are symmetrically arranged with respect to the third segment, and the third segment extends along the first direction Z.

[0067] Optionally, the angle between the first segment and the first direction Z is 40°-70°. Specifically, it can be 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., without limitation.

[0068] The first section forms an angle with the first direction Z, allowing the airflow to enter the third section at an oblique angle. This avoids turbulence and energy loss caused by the airflow colliding with the pipe wall when making a right-angle turn, ensuring smooth airflow.

[0069] The first and third sections are connected to the suction airway 112 and the microphone airway 111, respectively, to achieve independent transmission of multiple airflows. The unified outlet of the third section ensures that all airflows are discharged in a balanced manner. Furthermore, the multi-stage exhaust airway extends the airflow path, increases the adhesion time of condensate on the inner wall of the airway, and reduces the risk of it being discharged with the airflow or flowing back into the atomizing core 50.
