The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] In existing products, the liquid aerosol matrix in the atomization device may leak out from the aerosol airway due to reasons such as the device being tilted or inverted, thus affecting the user experience.

[0033] To solve the above problems in existing products, please refer to Figure 1-6 , the embodiment of the present application provides an atomization device 1, which mainly includes an atomization tube 10 and an atomization core 11;

[0034] The atomizing tube 10 is formed with an atomizing chamber 101, and has an air inlet end 103 and an air outlet end 104 which are opposite to each other in the axial direction, and the air inlet end 103 and the air outlet end 104 connect the atomizing chamber 101 with the outside of the atomizing tube 10;

[0035] An air guide tube 13 is fixedly provided at the air outlet end 104 of the atomizing tube 10, and the air guide tube 13 at least partially extends into the atomizing chamber 101; the air guide tube 13 is located on the outer wall of the atomizing chamber 101, and a liquid storage space 102 is formed between the air guide tube 13 and the inner wall of the atomizing tube 10, and the liquid storage space 102 is communicated with the atomizing chamber 101;

[0036] The atomizing core 11 is disposed in the atomizing chamber 101 near the air inlet end 103 , and the atomizing core 11 is used to heat the aerosol matrix to form an aerosol.

[0037] The atomizing device 1 in the embodiment of the present application is used to convert an aerosol matrix into an aerosol and discharge it; wherein, an atomizing chamber 101 is formed in the atomizing tube 10 of the atomizing device 1, and the atomizing chamber 101 is used to accommodate the atomizing core 11 and the aerosol processed by the atomizing core 11. The aerosol matrix enters the atomizing chamber 101, is heated by the atomizing core 11 to generate an aerosol, and is then discharged from the atomizing chamber 101. Therefore, according to the discharge direction of the aerosol, that is, the airflow direction, the atomizing tube 10 includes an air inlet end 103 and an air outlet end 104 along its axial direction, and the air inlet end 103 and the air outlet end 104 are arranged opposite to each other.

[0038] In order to discharge the aerosol, the air outlet end 104 on the atomizing tube 10 is fixedly provided with an air guide tube 13 connecting the atomizing chamber 101 with the outside. The air guide tube 13 itself is used for the circulation of the aerosol, and the circulation direction of the airway is also the exhaust direction of the air guide tube 13, specifically, along the axial direction of the air guide tube 13, from the inside of the atomizing chamber 101 to the outside. When the atomizing device 1 is arranged in the atomizing equipment, the air guide tube 13 is connected to the exhaust passage of the atomizing equipment, so the aerosol generated by the atomizing device 1 is discharged through the exhaust passage of the atomizing equipment.

[0039] The atomizer core 11 heats the aerosol matrix to convert the liquid aerosol matrix into aerosol, which is then discharged through the air duct 13; however, due to incomplete heating or aerosol condensation, there will be more or less liquid aerosol matrix in the atomizer chamber 101. In order to prevent the aerosol matrix from being discharged directly through the air duct 13 in liquid form, please continue to refer to Figure 2 and Figure 3 In the embodiment of the present application, at least a portion of the air guide tube 13 directly extends into the atomizing chamber 101; since a portion of the air guide tube 13 extends into the atomizing chamber 101, the inner wall of the atomizing tube 10 used to form the atomizing chamber 101 and the outer wall of the air guide tube 13 located in the atomizing chamber 101 will form a liquid storage space 102, and the liquid storage space 102 is connected to the atomizing chamber 101 itself, so when the liquid aerosol matrix exists in the atomizing chamber 101, it can also enter the liquid storage space 102. Since the liquid aerosol matrix will only adhere to the inner wall and flow, when the atomizing device 1 is tilted or inverted, under the action of gravity, the aerosol matrix will flow along the inner wall of the atomizing tube 10 to the liquid storage space 102, and finally converge at the liquid storage space 102, thereby effectively reducing or even avoiding the leakage of the aerosol matrix caused by the discharge of the aerosol matrix from the air guide tube 13, greatly improving the user experience.

[0040] In addition, when the atomizer 1 returns to an upright state from a tilted or inverted state, the aerosol matrix remaining in the liquid storage space 102 will flow back to the location of the atomizer core 11 under the action of gravity, so that the atomizer core 11 can be heated again to form an aerosol, thereby further improving the utilization rate of the aerosol matrix.

[0041] In some optional embodiments, please continue to refer to Figure 2-4In order to enhance the convergence effect of the aerosol matrix, the atomizing tube 10 has a first peripheral wall 18, which surrounds the air duct 13 and is connected to the air duct 13; at least the first peripheral wall 18 and the outer wall of the air duct 13 enclose a liquid storage space 102. The first peripheral wall 18 is arranged around the air duct 13, that is, the first peripheral wall 18 is the part of the atomizing tube 10 closest to the air duct 13; between the first peripheral wall 18 and the outer wall of the air duct 13, a liquid storage space 102 for accommodating the aerosol matrix or condensate is formed. Under this structure, the cross-sectional shape of the liquid storage space 102 is annular, which can be set according to the cross-sectional shape of the atomizing device 1, or can be set independently of the cross-sectional shape of the atomizing device 1, including but not limited to circular rings, elliptical rings, square rings, triangular rings, and other rings corresponding to regular or irregular shapes. When the atomizer 1 tilts in any direction, the aerosol matrix can be based on the inner wall of the atomizer tube 10, so that the aerosol matrix in each part of the liquid storage space 102 can flow along the inner wall of the atomizer tube 10 to the position of the first peripheral wall 18, so that it can be retained in the liquid storage space 102; after finally converging together, if the atomizer 1 is straightened again, the aerosol matrix in the liquid storage space 102 can flow back to the position of the atomizer core 11 through the outer wall of the air guide tube 13 or the first peripheral wall 18, reducing the occurrence of the aerosol matrix hanging on the wall and further improving the utilization rate of the aerosol matrix. The cross section in the embodiment of the present application refers to the cross section corresponding to the axial direction perpendicular to the corresponding component. For example, the cross section of the liquid storage space refers to the cross section corresponding to the axial direction perpendicular to the air guide tube or the atomizer tube.

[0042] At least the first circumferential wall 18 and the outer wall of the air duct 13 form a liquid storage space, including a case where the liquid storage space is formed by the combination of only the first circumferential wall 18 and the outer wall of the air duct 13; in this case, the first circumferential wall 18 can be a plane or a curved surface. When the first circumferential wall 18 is a plane, in order to form a liquid storage space, the first circumferential wall 18 can extend obliquely relative to the outer wall of the air duct 13, thereby forming a liquid storage space between the outer wall of the air duct 13 and the first circumferential wall 18.

[0043] In some optional embodiments, please continue to refer to Figure 5 The atomizing tube has a second peripheral wall 19, which is arranged around the air duct 13 and connected to the end of the first peripheral wall 18 away from the air duct 13; the first peripheral wall 18, the second peripheral wall 19 and the outer wall of the air duct 13 together enclose a liquid storage space 102. In this structure, the first peripheral wall 18 can directly extend outward perpendicularly to the outer wall of the air duct 13, and the second peripheral wall 19 can be perpendicular or inclined to the first peripheral wall 18 and extend in a direction away from the air duct 13, thereby enclosing an atomizing chamber 101.

[0044] In some optional embodiments, the liquid storage space 102 may be uniformly distributed along the circumference, that is, the cross-sectional shape of the liquid storage space is a symmetrical ring, so that the atomizing device 1 has the same retention effect on the aerosol matrix regardless of which direction it is tilted or inverted. And for the atomizing device 1, aligning the axis of the air guide tube 13 with the axis of the atomizing tube 10 can also improve the adaptability of the atomizing device 1, and can be applied to more types of atomizing equipment.

[0045] In some optional embodiments, please continue to refer to Figure 5 In order to maximize the liquid storage volume of the liquid storage space 102, the areas of any two cross sections of the liquid storage space are equal. Since the areas of any two cross sections of the liquid storage space 102 are equal, when the air guide tube 13 extends into the atomization chamber for the same length, the liquid storage space 102 between the atomization tube and the air guide tube 13 can accommodate more aerosol substrate, thereby further reducing the leakage of the aerosol substrate.

[0046] In addition, please continue to refer to Figure 2-Figure 4 In order to improve the efficiency of aerosol matrix reflux, the cross-sectional area of ​​the liquid storage space can also be set to gradually decrease from the end of the liquid storage space close to the atomization chamber to the end away from the atomization chamber. In this way, the aerosol matrix accommodated can quickly reflux along the inclined surface of the atomization tube 10 or the air guide tube 13 after the atomization device 1 is straightened, reducing the occurrence of aerosol matrix wall hanging phenomenon.

[0047] In some optional embodiments, please continue to refer to Figure 5 In order to achieve a fixed connection between the air guide tube 13 and the atomizer tube 10, the air guide tube 13 and the atomizer tube 10 can be directly integrally formed. Under the integrally formed structure, the sealing between the air guide tube 13 and the atomizer tube 10 can be fully guaranteed, and the process flow can be reduced to improve the operation efficiency. Depending on the material, the air guide tube 13 and the atomizer tube 10 can be made by injection molding, molding, cutting and other processes.

[0048] In some optional embodiments, please continue to refer to Figure 6In addition to setting the air guide tube 13 and the atomizer tube 10 based on an integrally formed structure, the atomizer tube 10 and the air guide tube 13 can also be separated in advance. In this structure, the air outlet end 104 of the atomizer tube 10 is provided with an opening 14 connecting the atomizer chamber 101 with the outside, and the air guide tube 13 is arranged through the opening 14, and the air guide tube 13 and the atomizer tube are sealed with each other at the opening to achieve a fixed connection between the air guide tube 13 and the atomizer tube 10. Based on the structure in which the air guide tube 13 and the atomizer tube 10 are pre-separated, the air guide tube 13 can be set on other components, such as a nozzle for forming an exhaust channel 21 on the atomizer device; the air guide tube 13 and the opening 14 cooperate with each other to achieve a fixed connection, and the air guide tube 13 and the opening 14 can be set to form an interference fit, so that the effects of fixed connection and sealing can be achieved at the same time.

[0049] In addition to the interference fit to achieve fixed connection, the air duct 13 and the opening 14 can also be fixedly connected by threaded fit, that is, an external thread can be provided on the outer wall of the air duct 13, and an internal thread matching the external thread of the air duct 13 can be provided on the inner wall of the opening 14, and the two can be fixedly connected by thread interlocking. In this structure, a seal can be provided between the air duct 13 and the opening 14 to achieve sealing between the two, wherein the seal can include an elastic silicone ring, or a sealant can be used to fill the connection between the air duct 13 and the opening 14.

[0050] In some optional embodiments, please continue to refer to Figure 6 In order to further improve the sealing effect between the atomizing tube 10 and the air guiding tube 13, prevent the aerosol matrix and the aerosol from leaking from the connection between the atomizing tube 10 and the opening 14, and guide the air guiding tube 13, the atomizing tube 10 may also include a limiting tube 15, which surrounds the edge of the opening 14 and extends in the axial direction of the atomizing tube 10 away from the atomizing chamber 101; the air guiding tube 13 is fixedly arranged in the limiting tube 15, and the contact between the air guiding tube 13 and the limiting tube 15 is sealed with each other. The structure of the limiting tube 15 is tubular, and the limiting tube 15 surrounds the air guide tube 13 therein, and the limiting tube 15 extends toward the end of the air guide tube 13 outside the atomization chamber 101, thereby increasing the contact area between the limiting tube 15 and the air guide tube 13, thereby reducing the possibility of leakage of aerosol matrix and aerosol from between the limiting tube 15 and the air guide tube 13; in addition, an interference fit can be formed between the limiting tube 15 and the air guide tube 13, and based on the interference fit, the stability of the fixed connection between the air guide tube 13 and the atomization tube 10 can be further improved, thereby preventing the air guide tube 13 from detaching from the atomization tube 10.

[0051] The air guide tube 13 and the position limiting tube 15 can also be fixedly connected by threaded matching, that is, an external thread can be set on the outer wall of the air guide tube 13, and an internal thread matching the external thread of the air guide tube 13 can be set on the inner wall of the position limiting tube 15, and the two can be fixedly connected by thread interlocking. A seal can also be set between the air guide tube 13 and the position limiting tube 15 to further improve the sealing performance between the air guide tube 13 and the atomizing tube 10. The seal can be an elastic silicone ring, or a sealant can be directly applied between the air guide tube 13 and the atomizing tube 10.

[0052] In some optional embodiments, please continue to refer to Figure 1-6 In order to heat the aerosol matrix, at least one liquid guide hole 16 is also provided on the atomizing tube 10. The atomizing core is provided in the atomizing chamber in the form of a capped liquid guide hole. The liquid guide hole is used to guide the aerosol matrix into the atomizing core, so that the aerosol matrix entering the atomizing chamber will theoretically be heated by the atomizing core to form an aerosol, thereby reducing the retention of the liquid aerosol matrix in the atomizing chamber. Considering the limitation on the efficiency of generating aerosol, a capillary liquid storage part can generally be provided on the atomizing core 11, and the aerosol matrix is ​​infiltrated through the capillary liquid storage part, and then the aerosol matrix is ​​heated to form an aerosol; and the capillary liquid storage part can effectively limit the excessive aerosol matrix from entering the atomizing chamber 101, thereby realizing the control of the aerosol generation efficiency. Among them, the capillary liquid storage part can include liquid storage cotton, ceramic liquid storage part, and the like.

[0053] In some alternative embodiments, please refer to Figure 7 In order to further reduce the possibility of leakage of the aerosol matrix from the air guide tube 13, a liquid-isolating and air-permeable blocking member 17 may be provided at the air inlet end of the air guide tube 13. The function of the blocking member 17 is to prevent the aerosol matrix from entering the air guide tube 13 by blocking the end of the air guide tube 13; in order to achieve the effect of liquid-isolating and air-permeable, that is, to block the liquid and allow the gas to pass normally, the structure of the blocking member 17 may include a plurality of fine micropores, which can block the liquid aerosol matrix and allow the aerosol to pass.
