[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0057] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 One embodiment of this application provides an atomizer 100, which includes:

[0058] The housing 10 has a liquid storage chamber 11 inside for storing liquid matrix.

[0059] The support 20 is provided with an atomizing core 30 for atomizing a liquid matrix to generate an aerosol, and a first ventilation channel 40 is provided between the support 20 and the atomizing core 30.

[0060] The exhaust channel 50 is configured to discharge aerosols.

[0061] The air intake channel 60 is configured to guide airflow to the atomizing core 30, the first air exchange channel 40, and the air outlet channel 50; and the air guide tube 70 is connected to the support 20. A second air exchange channel 71 is formed inside the air guide tube 70. The second air exchange channel 71 connects the liquid storage chamber 11 and the first air exchange channel 40 so that the first air exchange channel 40 and the liquid storage chamber 11 can exchange gases.

[0062] In this embodiment, the housing 10 is used to form a liquid storage chamber 11, and the liquid matrix is ​​a matrix that can be atomized by the atomizing core 30 to form an aerosol. In one embodiment, the liquid matrix is ​​e-liquid.

[0063] The evaporates or volatiles produced by the liquid matrix under the action of the atomizing core 30 can combine with the air introduced by the air intake channel 60 to form an aerosol. The aerosol flows into the air outlet channel 50 and is then discharged by the air outlet channel 50. The air entering through the air intake channel 60 can flow into the liquid storage chamber 11 through the first air exchange channel 40 and the second air exchange channel 71 in sequence to balance the air pressure between the liquid storage chamber 11 and the outside, thereby preventing negative pressure in the liquid storage chamber 11 or reducing the negative pressure degree of the liquid storage chamber 11, so that the liquid matrix in the liquid storage chamber 11 can flow smoothly to the atomizing core 30 for atomization.

[0064] When the liquid matrix in the storage chamber 11 is consumed, a negative pressure will appear in the storage chamber 11. The negative pressure will prevent the liquid matrix in the storage chamber 11 from flowing into the atomizing core 30, thus causing the atomizing core 30 to burn dry. Therefore, by setting the first ventilation channel 40 and the second ventilation channel 71, the air entering through the air intake channel 60 can enter the storage chamber 11 through the first ventilation channel 40 and the second ventilation channel 71 to balance the internal air pressure.

[0065] In some embodiments, the first ventilation channel 40 and the second ventilation channel 71 are independent of the channel that guides the liquid matrix in the liquid storage chamber 11 to the atomizing core 30. That is, on the support 20, the channel for ventilation and the channel for liquid guiding are independent of each other and do not communicate with each other. This can avoid different channels from affecting each other, achieve oil-gas separation, prevent ventilation bubbles from getting stuck in the area where liquid needs to be guided, make liquid guiding smooth, and thus improve liquid delivery efficiency and atomization volume.

[0066] The air duct 70 is used to set the second ventilation channel 71. The second ventilation channel 71 is formed through the air duct 70, rather than directly forming the second ventilation channel 71 on the support 20. The purpose is to improve the reliability of the second ventilation channel 71 through the structure of the air duct 70 itself, and to prevent the second ventilation channel 71 from becoming narrowed or blocked due to the support 20 being squeezed.

[0067] In some embodiments, the second ventilation channel 71 is a hole disposed within the air guide pipe 70. The cross-section of the hole can be circular, elliptical, rectangular, or other shapes. The hole has a suitable aperture to prevent leakage of the liquid matrix in the storage chamber 11 through the second ventilation channel 71 and to prevent the second ventilation channel 71 from being liquid-sealed by the liquid matrix in the storage chamber 11. The aperture diameter is the shortest distance between the two opposite sides of the hole. For example, when the hole is rectangular, the aperture diameter is the length of the shorter side of the rectangle; when the hole is elliptical, the aperture diameter is the length of the minor axis of the ellipse; and when the hole is circular, the aperture diameter is the diameter of the circle. More specifically, the aperture diameter d satisfies: 0.2mm ≤ d ≤ 0.8mm, preferably, the aperture diameter is approximately 0.5mm. If the aperture is too small, for example, less than 0.2mm, the liquid matrix in the storage chamber 11 can easily liquid-seale the opening of the hole facing the storage chamber 11, thereby hindering air from flowing into the storage chamber 11. If the aperture is too large, for example, when the aperture is greater than 0.8 mm, the liquid matrix in the storage chamber 11 is prone to leakage through the second ventilation channel 71.

[0068] In one embodiment, at least a portion of the support 20 is disposed within the housing 10 for assembly with the housing 10. Furthermore, the support 20 may define a portion of the boundary of the storage cavity 11.

[0069] In one embodiment, at least a portion of the air intake channel 60 and the air outlet channel 50 are located within the housing 10. Further, the housing 10 is provided with a mouthpiece 80 for a user to hold in their mouth. A connecting pipe is provided inside the housing 10, connecting the mouthpiece 80 and the support 20. At least a portion of the air outlet channel 50 is defined by the inner wall of the connecting pipe, and the air outlet channel 50 connects the atomizing core 30 and the mouthpiece. The aerosol formed by the combination of air entering through the air intake channel 60 and the evaporates or volatiles generated by the atomizing core 30 can be introduced into the mouthpiece through the air intake channel 60. Even further, at least a portion of the connecting pipe is located within the storage cavity 11.

[0070] In one embodiment, please refer to Figure 6 The support 20 is also provided with an airflow channel 21 and an air hole 22. The first ventilation channel 40 and the air inlet channel 60 are both connected to the airflow channel 21; simultaneously, the airflow channel 21 also connects the atomizing core 30 and the air outlet channel 50, so that the aerosol generated at the atomizing core 30 flows into the air outlet channel 50 through the airflow channel 21. At least a portion of the air hole 22 can accommodate the end of a connecting tube, thus connecting the airflow channel 21 and the air outlet channel 50.

[0071] Please continue to refer to this. Figure 3 In one embodiment, the air duct 70 includes a first end 72 facing the liquid storage chamber 11 and a second end 73 facing the first ventilation channel 40, the first end 72 being not covered by the support 20.

[0072] Furthermore, an opening 74 of the second ventilation channel 71 is formed on the first end 72. The air guide tube 70 is connected to the liquid storage chamber 11 through the opening 74. The first end 72 is not covered by the support 20, so the opening 74 can remain open. This prevents the support 20 from obstructing the connection between the second ventilation channel 71 and the liquid storage chamber 11, and ensures the smooth flow of air between the liquid storage chamber 11 and the second ventilation channel 71.

[0073] Please continue to refer to this. Figure 3 In one embodiment, the second end 73 is positioned in contact with or near the atomizing core 30 to absorb heat emitted by the atomizing core 30, and the air duct 70 is configured to conduct at least a portion of the heat absorbed by the second end 73 to the first end 72.

[0074] The heat dissipated by the atomizing core 30 through the air guide tube 70 is conducted to raise the temperature of the first end 72, thereby raising the temperature of the liquid matrix near the first end 72. This reduces the viscosity of the liquid matrix near the first end 72, preventing the liquid matrix from blocking the opening 74. This allows the gas in the first air exchange channel 40 to enter the liquid storage chamber 11 more easily, ensuring the smoothness and stability of the gas entering the liquid storage chamber 11.

[0075] In one embodiment, the air duct 70 includes a thermally conductive material.

[0076] The thermally conductive material includes materials with high thermal conductivity. High thermal conductivity means a thermal conductivity of at least 10 W / (m·K). In one embodiment, the thermal conductivity of the thermally conductive material is at least 40 W / (m·K), and in another embodiment, the thermal conductivity of the thermally conductive material is at least 100 W / (m·K). In yet another embodiment, the thermally conductive material includes, but is not limited to, graphite, graphene, aluminum, copper, zinc, steel, silver, thermally conductive polymers, or any combination or alloy thereof. As an example, the vent 70 is made of a material with high thermal conductivity, such as a metal. As an example, the vent 70 includes a base tube and a material with high thermal conductivity disposed on the base tube, such as a thermally conductive coating on the surface of the base tube.

[0077] In one embodiment, please refer to Figure 6 and Figure 7 The atomizing core 30 includes a porous body 31 and a heating element 32 disposed on the porous body 31. The porous body 31 is located between the second end 73 and the heating element 32, thereby making the heating element 32 spaced apart from the second end 73 to prevent the second end 73 from absorbing too much heat from the heating element 32 and becoming too hot, thereby preventing the temperature of the first end 72 from becoming too high and preventing the liquid matrix near the first end 72 from vaporizing or evaporating.

[0078] Furthermore, the second end 73 is spaced apart from the porous body 31. Even further, the distance between the second end 73 and the porous body 31 is between 0.1mm and 0.5mm to control the heat directed from the second end 73 to the first end 72, preventing the temperature of the first end 72 from becoming too high or too low. If the temperature of the first end 72 is too high, it will cause a large amount of liquid matrix in the liquid storage chamber 11 to vaporize, thereby increasing the gas pressure in the liquid storage chamber 11 and causing leakage; if the temperature of the first end 72 is too low, it will be difficult to break through the liquid seal of the viscous liquid matrix on the opening 74, thus causing poor airflow in the second ventilation channel 71.

[0079] Preferably, the heating element 32 is disposed on the side of the porous body 31 opposite to the second end 73. The porous body 31 is used to absorb the liquid matrix from the liquid storage chamber 11, and the heating element 32 is used to heat and atomize at least a portion of the liquid matrix absorbed by the porous body 31, causing it to atomize and generate an aerosol.

[0080] In one embodiment, please refer to Figure 5 The air guide tube 70 protrudes from the support 20 and is thus partially located in the liquid storage chamber 11. On the one hand, this prevents the first end 72 from being covered by the support 20, and on the other hand, it helps to reduce the hydraulic pressure on the air guide tube 70 toward the opening 74 of the liquid storage chamber 11, which helps to reduce the difficulty of air breaking through the liquid seal.

[0081] Furthermore, the length A of the vent tube 70 extending into the liquid storage chamber 11 is greater than or equal to 1 mm. Even further, A ≥ 3 mm. For example, the length A of the vent tube 70 extending into the liquid storage chamber 11 can be approximately 5.35 mm. The total length of the vent tube 70 can be between 5 mm and 15 mm.

[0082] In some embodiments, please refer to Figure 6 and Figure 7 The support 20 includes a base 23 and a first seal 24. The first seal 24 connects the base 23 and the housing 10 to provide a seal between them. The first seal 24 does not cover the opening 74 of the air duct 70 facing the liquid storage chamber 11. The first ventilation channel 40, the airflow channel 21, and the air hole 22 can all be located on the base 23. The air duct 70 can be connected to the base 23. The atomizing core 30 is located on the side of the base 23 away from the storage chamber 11. In one embodiment, a portion of the first seal 24 is disposed between the connecting pipe and the base 23 to provide a seal between the air duct and the base 23, ensuring a sealed connection between the air outlet channel 50 and the air hole 22.

[0083] In some embodiments, please refer to Figure 6 and Figure 7 The support 20 has a liquid guiding channel 25 for guiding the liquid matrix to the atomizing core 30. The opening 74 of the air guide pipe 70 facing the liquid storage chamber 11 is higher than the liquid guiding channel 25. The design of the opening 74 of the air guide pipe 70 facing the liquid storage chamber 11 being higher than the liquid guiding channel 25 allows the position of the opening 74 of the gas entering the liquid storage chamber 11 to be higher than the liquid outlet of the liquid guiding channel 25 facing the liquid storage chamber 11. This creates a vertical drop between the opening 74 and the liquid outlet, which can prevent air bubbles generated by the gas flowing into the storage chamber 11 from blocking the liquid outlet and thus hindering the flow of the liquid matrix in the storage chamber 11 into the liquid guiding channel 25 and the atomizing core 30.

[0084] In some embodiments, the air duct 70 and the liquid outlet are spaced laterally. This also aims to prevent air bubbles generated by gas flowing from the ventilation channel into the storage chamber 11 from clogging the liquid outlet and thus hindering the flow of the liquid matrix in the storage chamber 11 into the liquid duct 25 and the atomizing core 30.

[0085] Please refer to Figure 5 The air duct 70 is a straight pipe. This design shortens the path distance of the second ventilation channel 71 and improves ventilation efficiency.

[0086] Please continue to refer to this. Figure 6 , Figure 7 , Figure 9 and Figure 10In one embodiment, the support 20 is further provided with a mounting cavity 26, and the atomizing core 30 is at least partially disposed in the mounting cavity 26. The mounting cavity 26 includes a first inner wall 261 located between the liquid storage cavity 11 and the atomizing core 30 and a second inner wall 262 disposed at least partially around the atomizing core 30. The first inner wall 261 and the second inner wall 262 respectively define a portion of the boundary of the first ventilation channel 40.

[0087] Furthermore, the atomizing core 30 also includes a second seal 28, which surrounds the porous body and provides a seal between the support 20 and the porous body to prevent leakage of the liquid matrix along the sidewalls of the porous body. The second seal 28 may define a portion of the boundary of the first ventilation channel 40, or at least a portion of the first ventilation channel 40 may be disposed between the second seal 28 and the support 20. Thus, the air in the first ventilation channel 40 can absorb some of the heat emitted by the atomizing core 30.

[0088] Please continue to refer to this. Figure 7 , Figure 9 and Figure 10 In one embodiment, a first groove 41 is provided on the first inner sidewall 261, and a second groove 42 communicating with the first groove 41 is provided on the second inner sidewall 262. A portion of the first ventilation channel 40 is located in the first groove 41, and a portion is located in the second groove 42.

[0089] The first groove 41 can extend to directly communicate with the second groove 42. The first inner sidewall 261 and the second inner sidewall 262 can be arranged perpendicular to each other. Providing the first groove 41 and the second groove 42 extends the length of the first ventilation channel 40 on the support 20, helping to retain the liquid matrix entering the first ventilation channel 40 on the support 20 and preventing leakage. In one embodiment, one end of the second groove 42 communicates with the airflow channel 21 on the support 20, so that the first ventilation channel 40 communicates with the airflow channel 21.

[0090] In one embodiment, at least a portion of the first ventilation passage 40 is approximately "L" shaped.

[0091] Please continue to refer to this. Figure 5 In one embodiment, the support 20 is provided with a fitting hole 27, and the air guide tube 70 is at least partially disposed within the fitting hole 27; alternatively, the air guide tube 70 and the support 20 are injection molded together using an insert. This arrangement allows the air guide tube 70 to be stably fixed in the support 20.

[0092] Please continue to refer to this. Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 An embodiment of this application also provides an atomizer 100, which includes:

[0093] The housing 10 has an internal storage chamber 11 for storing a liquid matrix;

[0094] Support 20, the support 20 is provided with an atomizing core 30 for atomizing liquid matrix to generate aerosol;

[0095] The air duct 70 includes a heat-conducting material and is inserted into the support 20. An air exchange channel is formed inside the air duct 70 and is connected to the liquid storage chamber 11 to guide air into the liquid storage chamber 11.

[0096] The air guide tube 70 includes a first end 72 facing the liquid storage chamber 11 and a second end 73 facing the atomizing core 30, such that the second end 73 can absorb part of the heat emitted by the atomizing core 30, and the air guide tube 70 is configured to conduct at least part of the heat absorbed by the second end 73 to the first end 72.

[0097] In this embodiment, the air guide tube 70 allows the second end 73 to absorb some of the heat generated during the operation of the atomizing core 30 and transfer the heat to the first end 72. This causes the liquid matrix near the first end 72 in the liquid storage chamber 11 to be heated, reducing its viscosity and making it less likely to clog the ventilation channel inside the air guide tube 70. Simultaneously, the air guide tube 70 also prevents the internal ventilation channel from narrowing or becoming blocked due to compression.

[0098] In this embodiment, the ventilation channel within the air duct 70 can be the second ventilation channel 71 described in the above embodiment. In this embodiment, the first ventilation channel 40 is optional rather than mandatory.

[0099] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The atomizer 100 is equipped with a mouthpiece 80 for users to inhale aerosols.

[0100] Please continue to refer to this. Figure 4 An embodiment of this application also provides an atomizing device 1000, which includes:

[0101] Atomizer 100, which is any one of the atomizers 100 in the above embodiments;

[0102] Battery assembly 200 is electrically connected to atomizer core 30 of atomizer 100 and is used to power atomizer core 30.
