And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0031] In the embodiments of the present utility model, in order to reduce the influence of aerosol discharge in the aerosol generating device and at the same time increase the absorption amount of condensate, please refer to Figure 1-3 As shown, the embodiments of the present application provide an atomizing device 1, including:

[0032] A housing assembly 2, the housing assembly includes a mouthpiece, and a mouthpiece airway 21 is provided inside the mouthpiece; the housing assembly 2 has a liquid absorption chamber 22, wherein the liquid absorption chamber 22, the mouthpiece airway 21, and the outside of the mouthpiece are sequentially communicated;

[0033] An atomizing component 3, the atomizing component is arranged inside the housing assembly 2; for heating the aerosol matrix to generate aerosol; the atomizing component 3 includes an air duct 31 for guiding the aerosol to flow to the mouthpiece airway 21, and the air duct 31 at least partially extends into the liquid absorption chamber 22 to communicate with the liquid absorption chamber 22;

[0034] The liquid absorption member 4 is disposed in the liquid absorption chamber 22, and the liquid absorption member 4 is sleeved on the outer peripheral side of the air guide tube 31; there is a first gap L1 between the liquid absorption member 4 and the nozzle air passage 21 along the length direction of the air guide tube 31, and there is a second gap L2 between the air guide tube 31 and the nozzle air passage 21 along the length direction of the air guide tube 31, and the first gap L1 is smaller than the second gap L2.

[0035] Among them, the housing assembly 2 in the embodiment of the present application may be a wrapped structure, that is, the housing assembly 2 can accommodate the atomization assembly 3 therein, as Figure 1 shown; alternatively, the housing assembly 2 and the atomization assembly 3 may also be in a splicing structure, and the housing assembly 2 and the atomization assembly 3 can be spliced with each other in the up-down direction or the left-right direction to form the atomization device 1.

[0036] The housing assembly 2 includes a nozzle, and the housing assembly 2 and the nozzle may be integrally formed; alternatively, a fixed connection is formed between the housing assembly and the nozzle. A nozzle air passage 21 is formed inside the nozzle, and through the nozzle air passage 21, the aerosol generated by heating the aerosol matrix by the atomization assembly 3 can be discharged from the inside of the housing assembly 2 to the outside. During the discharge process, the high-temperature aerosol will generate condensate after cooling, and the condensate will adhere to the inner wall of the channel along the discharge path of the aerosol and flow back in the opposite direction of the discharge direction. Therefore, in the embodiment of the present application, a liquid absorption chamber 22 is provided, the liquid absorption chamber 22 is communicated with the nozzle air passage 21, and the condensate generated in the nozzle air passage 21 can flow back into the liquid absorption chamber 22, and the condensate generated in the liquid absorption chamber 22 remains in the liquid absorption chamber 22.

[0037] The atomization assembly 3 is disposed in the housing assembly 2, indicating that the atomization assembly 3 is fixedly connected to the housing assembly 2; the connection method may include: an installation chamber is formed inside the housing assembly 2, and the atomization assembly 3 is disposed in the installation chamber; alternatively, the housing assembly 2 and the atomization assembly 3 are spliced with each other to form the atomization device 1. The atomization assembly 3 is used to heat the aerosol matrix to generate aerosol.

[0038] In order to discharge the aerosol, the atomization assembly 3 has an air guide tube 31 for guiding the aerosol to flow to the nozzle air passage 21, and the air guide tube 31 at least partially extends into the liquid absorption chamber 22 to communicate with the liquid absorption chamber 22. Since the nozzle air passage 21 is communicated with the liquid absorption chamber 22, and the air guide tube 31 extends into the liquid absorption chamber 22 and is communicated with the liquid absorption chamber 22, the nozzle air passage 21 is also communicated with the air guide tube 31. In this structure, the generated aerosol can be discharged from the atomization device 1 after passing through the air guide tube 31, the liquid absorption chamber 22, and the nozzle air passage 21 in sequence.

[0039] In order to absorb the generated condensate, please refer to Figure 3, the liquid absorbent member 4 in the embodiment of the present application is further included in the atomizing device 1. The liquid absorbent member 4 is disposed in the liquid absorption chamber 22 and sleeved on the outer peripheral side of the air guide tube 31. Since the liquid absorbent member 4 is sleeved on the outer peripheral side of the air guide tube 31, the liquid absorbent member 4 can directly form a restraint through the connection relationship with the air guide tube 31, thereby improving the assembly convenience of the liquid absorbent member 4; moreover, the volume of the liquid absorbent member 4 is not affected by the gap between the air guide tube 31 and the mouthpiece, and the volume of the liquid absorbent member 4 can be increased to increase the absorption amount of the condensate; in addition, the liquid absorbent member 4 is sleeved on the outside of the air guide tube 31, which does not affect the airflow space inside the air guide tube 31, that is, the liquid absorbent member 4 does not affect the discharge amount of the aerosol. In order for the liquid absorbent member 4 to absorb the condensate, the liquid absorbent member 4 needs to be connected to the channel through which the aerosol is discharged; therefore, there is a first gap L1 between the liquid absorbent member 4 and the mouthpiece airway 21, and a second gap L2 between the air guide tube 31 and the mouthpiece airway 21, and the first gap L1 is smaller than the second gap L2. This means that neither the liquid absorbent member 4 nor the air guide tube 31 is directly connected to the mouthpiece airway 21, but each has a different interval, which brings the benefit to the liquid absorbent member 4 that it provides space for the liquid absorbent member 4 to expand when absorbing the condensate, and allows the liquid absorbent member 4 to absorb more condensate; and the second gap L2 between the air guide tube 31 and the mouthpiece airway 21 is larger than the first gap L1 between the liquid absorbent member 4 and the mouthpiece airway 21, which is equivalent to the air guide tube 31 being farther away from the mouthpiece airway 21 than the liquid absorbent member 4. Therefore, the liquid absorbent member 4 will communicate with the discharge channel of the aerosol at the second gap L2, so as to realize the absorption of the condensate.

[0040] The liquid absorbent member 4 in the embodiment of the present application can be an integral structure, or can also be formed by splicing multiple components.

[0041] In some alternative embodiments, in order to facilitate the discharge of the aerosol and reduce the retention of the condensate at corners, joints, etc., the mouthpiece airway 21 and the air guide tube 31 can be coaxially arranged. Since the mouthpiece airway 21 and the air guide tube 31 are coaxially arranged, the aerosol generated by the atomization assembly 3 can be directly discharged without turning, improving the discharge convenience of the aerosol; and since the mouthpiece airway 21 and the air guide tube 31 are coaxially arranged, the liquid absorbent member 4 surrounding the outer peripheral side of the air guide tube 31 is also coaxially arranged with the mouthpiece airway 21 and the air guide tube 31, which is equivalent to the liquid absorbent member 4 can absorb the condensate uniformly along the axis.

[0042] In some alternative embodiments, to facilitate the user's suction to generate negative pressure, enhance the convenience of aerosol discharge, and at the same time reduce the possibility of condensate flowing out from the nozzle airway 21, the inner diameter of the nozzle airway 21 can be configured to be less than or equal to the outer diameter of the air duct 31. Since the nozzle airway 21 and the air duct 31 are coaxially arranged, the smaller the inner diameter of the nozzle airway 21, the faster the gas flow rate and the lower the pressure during suction, which can enhance the guiding effect on the aerosol; and because the inner diameter of the nozzle airway 21 is small, the condensate is not easily discharged from the nozzle airway 21.

[0043] In some alternative embodiments, to increase the absorption amount of the liquid absorbent member 4 for the condensate, the liquid absorbent member 4 can be configured to be filled and arranged in the liquid absorption chamber 22 from a position close to the nozzle airway 21, and the liquid absorbent member 4 extends along the length direction of the air duct 31 to the bottom wall of the liquid absorption chamber 22; wherein, the bottom wall is the inner wall of the liquid absorption chamber 22 that is far from the nozzle airway 21 along the length direction of the air duct 31. In other words, the liquid absorbent member 4 is filled in the liquid absorption chamber 22. In the entire liquid absorption chamber 22, except for the first gap formed between the liquid absorbent member 4 and the nozzle airway 21, other spaces are occupied by the liquid absorbent member 4 and the air duct 31, which also means that the part of the air duct 31 extending into the liquid absorption chamber 22 is sleeved by the liquid absorbent member 4. This can increase the absorption amount of the condensate without affecting the amount of aerosol discharged by the air duct 31, and avoid the condensate from affecting the user's suction experience.

[0044] In some alternative embodiments, please refer to Figure 3 , since condensate is also generated in the nozzle airway 21, to absorb the condensate in the nozzle airway 21, a round chamfer 23 is provided at the end of the nozzle airway 21 close to the liquid absorbent member 4. Since a round chamfer 23 is provided at the end of the nozzle airway 21 close to the liquid absorbent member 4, that is, the air inlet end of the nozzle airway 21, the condensate generated in the nozzle airway 21 can flow along the round chamfer 23 to the first gap between the nozzle airway 21 and the liquid absorbent member 4, and thus be captured by the liquid absorbent member 4, realizing the absorption of the condensate in the nozzle airway 21.

[0045] In some alternative embodiments, please refer to Figure 4-7As shown, in order to heat the aerosol matrix and discharge the aerosol generated by heating, the atomization assembly 3 may specifically include an atomization tube 32 and a heating element 33. Among them, an atomization channel coaxial with the air guide tube 31 is provided inside the atomization tube 32, and the heating element 33 is arranged in the atomization channel. The air guide tube 31 is communicated with the atomization tube 32, and the air guide tube 31 and the atomization tube 32 are sealed with each other at the connection. An atomization channel is formed inside the atomization tube 32, and the heating element 33 is arranged in the atomization channel. Therefore, the generated aerosol is also located in the atomization channel. The connection between the air guide tube 31 and the atomization tube 32 is sealed to prevent the aerosol from leaking through the gap between the air guide tube 31 and the atomization tube 32. The generated aerosol will also be discharged along the connection between the atomization tube 32 and the air guide tube 31, and discharged from the atomization device 1 along the air guide tube 31, the liquid suction chamber 22 and the nozzle airway 21.

[0046] Among them, the sealing and communicating manner between the air guide tube 31 and the atomization tube 32 may be to insert the air guide tube 31 into the atomization tube 32, or to insert the atomization tube 32 into the air guide tube 31.

[0047] In some alternative embodiments, please refer to Figure 5 , in order to heat the aerosol matrix, the housing assembly 2 further has a liquid storage space 34. A liquid storage member 35 for storing the aerosol matrix is arranged in the liquid storage space 34. The liquid storage member 35 is arranged around the outer peripheral side of the atomization tube 32. A liquid inlet is provided on the tube wall of the atomization tube 32, and the liquid inlet communicates the liquid storage space 34 and the atomization channel. In other words, the housing assembly 2 in the embodiment of the present application forms a liquid storage space 34 for storing liquid, and an atomization tube 32 and a heating element 33 for heating. A liquid storage member 35 is arranged in the liquid storage space 34. The liquid storage member 35 may specifically include a capillary liquid storage structure such as liquid storage cotton or liquid storage ceramics. The atomization tube 32 and the heating element 33 are also arranged in the liquid storage space 34. The liquid storage member 35 is arranged around the atomization tube 32. Since a liquid inlet communicating the liquid storage space 34 and the atomization channel is provided on the tube wall of the atomization tube 32, the aerosol matrix stored in the liquid storage member 35 can be conducted into the atomization tube 32 through the liquid inlet, so that the heating element 33 can heat the aerosol matrix.

[0048] In some alternative embodiments, please refer to Figure 1 , Figure 4 and Figure 5, in order to avoid leakage of the aerosol matrix or aerosol inside, the air duct 31 extends at least partially into the liquid storage space 34, and the housing assembly 2 further includes a first seal 24. The first seal 24 is located in the liquid storage space 34 and is disposed around the outer periphery of the air duct 31, so that the liquid storage space 34 and the liquid suction chamber 22 are isolated from each other on the outer periphery of the air duct 31. The first seal 24 is disposed around the outer periphery of the air duct 31, which makes the possible assembly gap between the air duct 31 and the housing assembly 2 not communicate with each other between the liquid storage space 34 and the liquid suction chamber 22. The aerosol matrix and aerosol cannot escape from the liquid storage space 34 through the outside of the air duct 31. The aerosol matrix will remain in the liquid storage space 34, and the aerosol will flow out along the air flow direction of the atomizing tube 32 - air duct 31 - liquid suction chamber 22 - nozzle airway 21 according to the communication relationship between the atomizing tube 32 and the air duct 31.

[0049] In some alternative embodiments, the housing assembly 2 may be an integral structure or may be composed of multiple components. Specifically, the housing assembly 2 may include an outer shell 25, a lining 26, and a second seal 27 disposed between the outer shell 25 and the lining 26. The second seal 27 is located at the air inlet end of the nozzle airway 21, and the second seal 27 is fixedly connected to the lining 26. The outer shell 25 forms the nozzle airway 21, and the second seal 27 and the lining 26 enclose to form the liquid suction chamber 22. The second seal 27 seals the liquid suction chamber 22. By setting the housing assembly 2 to be formed by splicing multiple components, structures required can be made of different materials according to the design requirements of each component in the atomizing device 1 without being restricted by the same material. At the same time, the required structures can also be produced by different manufacturing processes, reducing the design and production costs. Among them, the housing assembly 2 includes the outer shell 25 and the lining 26 that are fixedly connected to each other, where the outer shell 25 is disposed to cover the lining 26, and the lining 26 forms a receiving space. The receiving space of the lining 26 can integrally form the required nozzle airway 21, liquid suction chamber 22, and even the liquid storage space 34, etc., or can be formed by splicing with other components.

[0050] For example, in order to achieve sealing, the housing assembly 2 further includes a second seal 27, where the second seal 27 is located at the air inlet end of the nozzle airway 21, and the second seal 27 is fixedly connected to the lining 26, that is, the second seal 27 is disposed at the air inlet end of the nozzle airway 21. Through the second seal 27, the connection between the nozzle airway 21 and the liquid suction chamber 22 can be sealed, avoiding leakage of condensate and even aerosol from the connection between the two. Therefore, it is equivalent that the second seal 27 and the lining 26 enclose to form the liquid suction chamber 22, and the liquid suction chamber 22 communicates with the nozzle airway 21.

[0051] In some alternative embodiments, the above-mentioned inner liner 26 may further be formed with a liquid replenishing space 28 and a liquid storage space 34 that communicate with each other. The atomization assembly 3 is disposed in the liquid storage space 34; the atomization device 3 further includes a liquid replenishing device 6. The liquid replenishing device 6 is disposed in the liquid replenishing space 28 and communicates with the atomization assembly 3, and is used to replenish the aerosol matrix for the atomization assembly 3; a second seal 27 is disposed at the opening of the liquid replenishing space 28 and sleeved outside the inner liner 26, and is used for fixedly connecting the liquid replenishing device 6. In the embodiment of the present application, the inner liner 26 may form an accommodation space for accommodating other components, including a liquid replenishing space 28 for accommodating the liquid replenishing device 6 and a liquid storage space 34 for accommodating the atomization assembly 3; since the liquid replenishing device 6 in the liquid replenishing space 28 is used to replenish the aerosol matrix for the atomization assembly 3, the liquid replenishing space 28 and the liquid storage space 34 communicate with each other so that the aerosol matrix can flow into the liquid storage space 34. In order to fixedly connect the liquid replenishing device 6 in the liquid replenishing space 28, the second seal 27 may also be sleeved outside the inner liner. Through the elastic action of the second seal 27, while forming a sealed connection between the outer shell 25 and the inner liner 26, the liquid replenishing device 6 is also fixedly connected to the inner liner 26, which can prevent the liquid replenishing device 6 from detaching from the liquid replenishing space 28.

[0052] The liquid replenishing device 6 is used to replenish the aerosol matrix for the atomization assembly 3; that is to say, the liquid replenishing device 6 can store the aerosol matrix and then replenish the aerosol matrix into the liquid storage space 34 in the atomization assembly 3. To achieve this purpose, the accommodation space of the liquid replenishing device 6 and the liquid storage space 34 can communicate with each other, so as to realize the conduction of the aerosol matrix from the liquid storage device to the liquid storage space 34.

[0053] To facilitate the liquid replenishing device 6 to replenish the aerosol matrix, the opening of the liquid replenishing device 6 can be provided at the bottom, so as to facilitate the discharge of the aerosol matrix from the opening. In addition, a liquid guiding structure 7 may be provided between the liquid replenishing device 6 and the atomization assembly 3. On the one hand, it can be used to guide the aerosol matrix to flow from the liquid replenishing device 6 into the atomization assembly 3, and on the other hand, it can limit the flow of the aerosol matrix flowing in from the liquid replenishing device 6 to prevent the inflow amount per unit time from being too large.

[0054] The embodiment of the present application provides an atomization device 1. Since the liquid absorbing member 4 is sleeved outside the air guiding tube 31, the installation convenience of the liquid absorbing member 4 is improved. At the same time, the liquid absorbing member 4 is not affected by the space between the air guiding tube 31 and the suction nozzle, and a larger-sized liquid absorbing member 4 can be set to increase the absorption amount of the condensate; and there is a gap between the liquid absorbing member 4 and the suction nozzle airway 21, which provides an expansion space for the liquid absorbing member 4, and further greatly improves the absorption amount of the condensate by the liquid absorbing member 4.

[0055] In the embodiment of the present application, an aerosol generating device is also provided. Please refer to Figure 2-5 As shown, the aerosol generating device includes a power supply device 5 and the above-mentioned atomization device 1;

[0056] Among them, the power supply device 5 is electrically connected to the atomization component 3 and is used to supply power to the atomization component 3.

[0057] Among them, the housing component 2 can provide a corresponding accommodation space for the power supply device 5, so that the power supply device 5 can be arranged inside the housing component 2. The power supply device 5 is used to supply power to the atomization component 3, so that the atomization component 3 can heat the aerosol matrix to generate aerosol. Therefore, the power supply device 5 can be directly or indirectly electrically connected to the atomization component 3. The power supply device 5 can be located on the side of the atomization component 3 facing away from the mouthpiece, so that the atomization component 3 and the liquid replenishing device 6 are on the same side of the power supply device 5, which is convenient for reserving enough space for the atomization component 3 and the liquid replenishing device 6; since the liquid absorbing member 4 of the atomization component 3 is slender, the liquid replenishing space 28 reserved for the liquid replenishing device can be as large as possible to ensure the capacity of the aerosol matrix of the atomization device 1.

[0058] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or replacements can also be made.
