The bottom wall 24 of the atomizer seat 2 serves as the bottom of the liquid storage chamber 10, and the liquid storage chamber 10 stores an aerosol generating matrix. It can be understood that in order to better seal the accommodating cavity 11 , a sealing member may also be provided between the periphery of the bottom wall 24 of the atomizer seat 2 and the inner wall surface of the housing 1 .

The cross-sectional shape of the annular side wall 26 of the atomizer seat 2 is not limited; preferably, the first side wall 21 is a planar structure, which is convenient for assembling the atomizer core 3 of the flat structure.

The fixing member 41 may be a metal member, which is not easily deformed and has a better fixing effect on the atomizer core 3. It is understandable that a card slot may be provided on the second side wall 22 and the third side wall 23, and a protrusion may be provided on the blocking member 412 for card connection.

It can be understood that in other embodiments, the first liquid inlet hole 410 may not be set in the center of the fixing member 41. For example, the fixing member 41 can be set to a mesh structure, and the aerosol generating matrix in the liquid storage chamber 10 can enter the atomizer core 3 through multiple micropores in the mesh fixing member 41; or, the size of the first body portion 411 of the fixing member 41 is smaller than the size of the mounting hole 211, and the first body portion 411 of the fixing member 41 is set corresponding to the position of the mounting hole 211 and is smaller than the width of the atomizer core 3, so that the atomizer core 3 is partially exposed in the liquid storage chamber 10, so that the atomizer core 3 is connected to the liquid storage chamber 10, so that the aerosol generating matrix in the liquid storage chamber 10 enters the atomizer core 3 through both sides of the first body portion 411 of the fixing member 41.

The second body portion 421 of the sealing member 42, the raised portion 422 and the atomizer core 3 block the mounting hole 211 to prevent the aerosol-generating matrix in the liquid storage chamber 10 from leaking into the atomizer chamber 20 through the mounting hole 211. Preferably, the raised portion 422 is interference-fitted between the side wall of the mounting hole 211 and the side wall of the atomizer core 3.

As shown in FIG. 10 , in this embodiment, the protrusion 422 of the sealing member 42 is an annular protrusion 422, and the shape of the annular protrusion 422 is a rectangular ring. The inner surface of the annular protrusion 422 is spaced apart from the side of the second liquid inlet hole 423, and the annular protrusion 422 cooperates with the second body part 421 to form a first groove 424, the side of the first groove 424 is the inner surface of the annular protrusion 422, and the bottom surface of the first groove 424 is the surface of the second body part 421 close to the electrical connector 6, and the atomizer core 3 is arranged in the first groove 424 and covers the second liquid inlet hole 423. The depth of the first groove 424 can be greater than or equal to the thickness of the atomizer core 3, or less than the thickness of the atomizer core 3. In this embodiment, the depth of the first groove 424 is equal to the thickness of the atomizer core 3, so that the atomizer core 3 can be stably installed in the first groove 424. The sealing member 42 plays a good role in fixing the atomizer core 3, and at the same time facilitates the electrical connector 6 to abut against the atomizing surface 31 of the atomizer core 3, thereby ensuring effective contact between the atomizer core 3 and the electrical connector 6.

It can be understood that by fixing the atomizer core 3 in the first groove 424 of the sealing member 42, the protrusion 422 of the sealing member 42 is embedded between the side wall of the atomizer core 3 and the side wall of the mounting hole 211, and then the fixing member 41 is fixedly connected to the second side wall 22 and the third side wall 23 of the atomizer seat 2, the fixing member 41 fixes the side of the sealing member 42 away from the electrical connector 6, and the side of the electrical connector 6 abuts against the atomizing surface 31 of the atomizer core 3. The atomizer core 3 is clamped and fixed in the mounting hole 211 by the fixing assembly 4 and the electrical connector 6 arranged on the opposite sides of the atomizer core 3, so that the contact between the electrical connector 6 and the atomizing surface 31 of the atomizer core 3 is more stable, and the abutment of the side of the electrical connector 6 against the atomizing surface 31 will not cause damage to the atomizer core 3.

In this embodiment, the atomizing surface 31 of the atomizing core 3 is a plane parallel to the axial direction A1 of the atomizer 100. As shown in FIG4 , the atomizing surface 31 is flush with the inner surface of the first side wall 21 of the atomizing seat 2, so that the side of the electrical connector 6 can be better in contact with the atomizing surface 31 of the atomizing core 3, and the problem of unstable contact between the electrical connector 6 and the atomizing core 3 is prevented when the atomizing surface 31 is located in the mounting hole 211 and is not flush with the inner surface of the first side wall 21. At the same time, compared with the atomizing surface 31 protruding from the inner surface of the first side wall 21, the atomizing surface 31 is flush with the inner surface of the first side wall 21 of the atomizing seat 2, which can also prevent the atomizing core 3 from blocking the airflow in the atomizing chamber 20, so that the airflow can flow smoothly through the atomizing chamber 20, and the atomizer 100 has a higher atomization efficiency.

In other embodiments, the shape of the raised portion 422 of the sealing member 42 may also be other shapes. For example, the raised portion 422 may be a plurality of protrusions arranged around the second liquid inlet hole 423, and the plurality of protrusions are embedded between the side wall of the mounting hole 211 and the side wall of the atomizer core 3 to fix the sealing member 42 and the atomizer core 3 in the mounting hole 211.

Furthermore, as shown in FIG. 4 , the sealing member 42 further includes a sealing ring 426 , which is disposed on the inner surface of the bottom wall of the first groove 424 and surrounds the second liquid inlet hole 423 to further seal the atomizer core 3 .

Further, as shown in FIG4 , the atomizer 100 further includes a liquid guide member 5, which is disposed in the second liquid inlet hole 423. Specifically, as shown in FIG10 , the sealing member 42 has a second groove 425, which is disposed at the connection position between the side of the second liquid inlet hole 423 and the surface of the second body portion 421 close to the atomizing core 3, and the edge of the liquid guide member 5 is embedded in the second groove 425, and the size of the second groove 425 is smaller than the size of the first groove 424. In this embodiment, the liquid guide member 5 is rectangular in shape, and the liquid guide member 5 is a sheet-like liquid guide member 5. Specifically, the liquid guide member 5 is a porous structure, and the liquid guide member 5 can be a structure such as liquid guide cotton, porous ceramics, etc. The liquid guide member 5 is connected to the liquid storage chamber 10 through the first liquid inlet hole 410 and the second liquid inlet hole 423. The surface of the liquid guide member 5 close to the electrical connector 6 contacts the liquid absorption surface 32 of the atomizer core 3. The aerosol-generating matrix in the liquid storage chamber 10 enters the liquid guide member 5 through the first liquid inlet hole 410 and the second liquid inlet hole 423, and is transported to the atomizer core 3 by the liquid guide member 5 to be heated and atomized by the atomizer core 3. It can be understood that the second groove 425 may not be provided, and the liquid guide member 5 may be clamped and fixed by the first body portion 411 of the fixing member 41 and the atomizer core 3. For example, the size of the second liquid inlet hole 423 and the liquid guide member 5 is set to be larger than the size of the first liquid inlet hole 410.

11 and 12 , FIG. 11 is a schematic structural diagram of the atomizer core of the atomizer provided in FIG. 2 , and FIG. 12 is a schematic structural diagram of the electrical connector of the atomizer provided in FIG. 2 .

In this embodiment, referring to FIG. 4 and FIG. 11 , the atomizing surface 31 of the atomizing core 3 is a plane arranged parallel to the axial direction A1 of the atomizer 100 , and the electrical connector 6 is a columnar structure, and two electrical connectors 6 are arranged in parallel and spaced apart.

As shown in Figure 11, the atomization core 3 includes a sheet-like liquid-conducting liquid 30 and a heating element 33. The sheet-like liquid-conducting liquid 30 is roughly rectangular. The sheet-like liquid-conducting liquid 30 includes a liquid absorption surface 32 and an atomization surface 31 that are relatively arranged. The atomization surface 31 is a plane parallel to the axial direction A1 of the atomizer 100. The heating element 33 is arranged on the atomization surface 31. The heating element 33 includes a metal heating film (not shown) and an electrode 331, which is used to heat the atomized aerosol to generate a substrate to generate an aerosol. In this embodiment, the metal heating film is S-shaped and is integrally formed with the electrode 331. The sheet-like liquid-conducting liquid 30 can be made of a porous ceramic material, or a sheet-like liquid-conducting liquid 30 with a porous structure can be formed by opening holes (such as through holes) in dense ceramics or glass.

As shown in FIG12 , in this embodiment, the electrical connector 6 is a cylindrical metal ejector pin, which is disposed on the bottom wall 24 of the atomizer seat 2 and passes through the assembly hole 241 of the bottom wall 24 of the atomizer seat 2 to enter the atomizer chamber 20. Specifically, the cylindrical metal ejector pin includes a cylindrical body 61 and a first annular protrusion 62 located on the side of one end of the cylindrical body 61, the first annular protrusion 62 protrudes from the side of the cylindrical body 61 and has a cylindrical outer contour, wherein the diameter of the first annular protrusion 62 is smaller than the aperture of the assembly hole 241, so that the first annular protrusion 62 of the electrical connector 6 can pass through the assembly hole 241 to enter the atomizer chamber 20, and the side of the first annular protrusion 62 abuts against the electrode 331 of the heating element 33 to achieve electrical connection between the electrical connector 6 and the atomizer core 3.

The metal ejector pin also includes a second annular protrusion 63 and a limiting protrusion ring 64. The second annular protrusion 63 protrudes from the side of the cylindrical body 61. The second annular protrusion 63 is correspondingly installed in the assembly hole 241 of the bottom wall 24 of the atomizer seat 2. The limiting protrusion ring 64 protrudes from the side of the second annular protrusion 63, that is, the diameter of the limiting protrusion ring 64 is larger than the aperture of the assembly hole 241. The limiting protrusion ring 64 limits the second annular protrusion 63 of the electrical connector 6 in the assembly hole 241, so that the electrical connector 6 can be stably assembled.

It can be understood that in other embodiments, the electrical connector 6 can also be set to a columnar structure of other shapes. For example, the electrical connector 6 can be set to any prism-shaped structure such as a triangular prism, a quadrangular prism, a pentagonal prism, etc., as long as the side of the electrical connector 6 can stably abut against the atomizing surface 31 of the atomizer core 3 and will not cause damage to the atomizer core 3.

Continuing to refer to Figures 6 and 7, the annular side wall 26 of the atomizer seat 2 is provided with a liquid storage ventilation channel 27, which connects the atmosphere and the liquid storage chamber 10, and is used to ventilate the liquid storage chamber 10 while also storing a certain amount of aerosol generation matrix. Specifically, the inner surface of the annular side wall 26 is provided with a plurality of first liquid storage tanks 271, and the first liquid storage tank 271 is arranged in a vertical direction, that is, parallel to the axial direction A1 of the atomizer 100, and is used to buffer the leakage and condensate generated during the user's suction process. The outer surface of the annular side wall 26 is provided with a plurality of second liquid storage tanks 272, the first liquid storage tank 271 and the second liquid storage tank 272 are fluidically connected, the second liquid storage tank 272 and the liquid storage chamber 10 are fluidically connected, and the first liquid storage tank 271 and the second liquid storage tank 272 cooperate with each other to form a liquid storage ventilation channel 27. As shown in Figure 7, the multiple second liquid storage tanks 272 arranged on the outer surface of the annular side wall 26 include multiple second liquid storage tanks 272 arranged along the circumference of the annular side wall 26 and a second liquid storage tank 272 arranged along the vertical direction. The multiple second liquid storage tanks 272 are interconnected. The second liquid storage tanks 272 can cache the aerosol generating matrix squeezed out of the liquid storage chamber 10 due to the increase of negative pressure in the liquid storage chamber 10. When the pressure in the liquid storage chamber 10 is released and the air pressure in the liquid storage chamber 10 returns to normal, the aerosol generating matrix cached in the first liquid storage tank 271 and the second liquid storage tank 272 can also flow back into the liquid storage chamber 10 and be reused.

It can be understood that by providing a liquid storage ventilation channel 27 on the annular side wall 26 of the atomizer seat 2, the liquid storage chamber 10 can be ventilated to ensure that the air pressure in the liquid storage chamber 10 is normal, thereby ensuring that the aerosol-generating matrix in the liquid storage chamber 10 can flow smoothly to the atomizer core 3, ensuring smooth and sufficient liquid supply to the atomizer core 3, and then ensuring that the atomization process proceeds smoothly. At the same time, it can also effectively prevent the liquid storage chamber 10 from leaking and the user from leaking when inhaling, thereby improving the atomization performance of the atomizer 100.

In this embodiment, the width of the first liquid storage tank 271 and the second liquid storage tank 272 is in the range of 0.3-06 mm, the depth of the second liquid storage tank 272 and the second liquid storage tank 272 is in the range of 0.3-0.6 mm, and the port area of the first liquid storage tank 271 and the second liquid storage tank 272 is in the range of 0.07-0.13 square millimeters, ensuring that the first liquid storage tank 271 and the second liquid storage tank 272 can effectively store leaked liquid. As shown in FIG7 , the air inlet end of the second liquid storage tank 272 is connected to the first liquid storage tank 271, and the air outlet end 2721 of the second liquid storage tank 272 is connected to the bottom fluid of the liquid storage chamber 10, that is, the end of the second liquid storage tank 272 arranged in the vertical direction away from the air outlet channel 12 extends to the bottom of the liquid storage chamber 10, and the bottom of the liquid storage chamber 10 is the bottom wall 24 of the atomizer seat 2. It can be understood that by extending the air outlet end 2721 of the second liquid storage tank 272 to the bottom of the liquid storage chamber 10, the aerosol generation matrix in the liquid storage chamber 10 is less, and the liquid storage chamber When the liquid level in 10 is low, the aerosol-generating matrix in the liquid storage chamber 10 can still enter the second liquid storage tank 272 through the air outlet 2721 of the second liquid storage tank 272, and the liquid can still be buffered in the liquid storage ventilation channel 27 to prevent leakage. At the same time, external gas can still enter the liquid storage chamber 10 through the air outlet 2721 of the second liquid storage tank 272 to ventilate the liquid storage chamber 10, making the ventilation process more stable. At the same time, the port area of the air outlet 2721 of the second liquid storage tank 272 is small, and it is easy to form an oil film to ensure the liquid storage effect.

Referring to FIG. 3 and FIG. 4 , the atomizer 100 provided in the present application further includes a base 7, which is arranged at one end of the atomizer seat 2 away from the air outlet channel 12, and is at least partially arranged in the accommodating chamber 11 of the housing 1, and the base 7 is used to further block the accommodating chamber 11 and fix the atomizer seat 2. As shown in FIG. 13 , the base 7 is provided with two avoidance holes 71, and the two avoidance holes 71 are arranged corresponding to the position of the assembly hole 241 of the bottom wall 24 of the atomizer seat 2. After the electrical connector 6 is installed in the assembly hole 241, one end located outside the atomizer chamber 20 is inserted into the avoidance hole 71 and exposed through the avoidance hole 71, that is, the bottom end of the electrical connector 6, that is, the end of the electrical connector 6 away from the air outlet channel 12 is exposed through the avoidance hole 71, and the end face of the end of the electrical connector 6 away from the air outlet channel 12 is arranged parallel to the bottom surface of the base 7, so that the bottom end of the electrical connector 6 is in good contact with the power supply assembly 200, thereby realizing the electrical connection between the atomizer 100 and the power supply assembly 200. An air inlet hole 72 is also provided between the two avoidance holes 71 . The number of the air inlet holes 72 can be set to one or more. The air inlet hole 72 on the base 7 is fluidly connected with the air inlet port 242 provided on the atomizer seat 2 . External gas enters the air inlet port 242 through the air inlet hole 72 and then enters the atomizer chamber 20 .
