Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an atomizing mechanism and an aerosol generation device. Background Technology

[0002] Atomizing mechanisms typically include a housing and an atomizing component. The atomizing component is housed within the housing, and the housing defines a liquid storage chamber for storing a liquid matrix. The atomizing component is provided with a liquid guide port, which connects to the liquid storage chamber. This allows the atomizing component to heat the liquid matrix from the liquid storage chamber to generate an aerosol for the user to inhale.

[0003] However, in the process of implementing the embodiments of this utility model, the inventors discovered that: currently, since the atomizing component is connected to the liquid storage chamber through the liquid guide port, the liquid matrix in the liquid storage chamber directly enters the atomizing component. When the atomizing mechanism is not used and is left for a long time, the liquid matrix is ​​prone to leakage. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an atomizing mechanism and an aerosol generating device, which aims to solve the technical problem that the liquid matrix is ​​prone to leakage when the atomizing mechanism is not used and is left for a long time.

[0005] To solve the above-mentioned technical problems, the present invention provides an atomizing mechanism, including a housing, an atomizing component, a base, and a sealing component. The housing defines a liquid storage chamber for storing a liquid matrix. The atomizing component is disposed within the housing and has a liquid guide port for the liquid matrix to enter. The base is connected to the atomizing component. The sealing component includes a first sealing element and a second sealing element, which are spaced apart from each other on the atomizing component. The first sealing element and the second sealing element are located on opposite sides of the liquid guide port. The second sealing element is closer to the base than the first sealing element. The base can move the atomizing component relative to the housing between a first position and a second position. When the base is in the first position, the first sealing element is located between the housing and the atomizing component to seal the liquid storage chamber, preventing the liquid matrix from entering the liquid guide port. When the base is in the second position, the second sealing element is located between the housing and the atomizing component to seal the liquid storage chamber, allowing the liquid matrix to enter the liquid guide port.

[0006] Optionally, the outer casing is provided with a through hole, which communicates with the liquid storage chamber;

[0007] The first seal or the second seal seals the gap between the sidewall of the through hole and the atomizing component.

[0009] Optionally, one of the outer wall of the base and the outer shell is provided with a first snap-fit ​​structure, and the other is provided with a second snap-fit ​​structure and a third snap-fit ​​structure. When the base is in the first position, the first snap-fit ​​structure snaps into the second snap-fit ​​structure, and the first seal seals the liquid storage cavity. When the base is in the second position, the first snap-fit ​​structure snaps into the third snap-fit ​​structure, and the second seal seals the liquid storage cavity.

[0010] Optionally, the first snap-fit ​​structure is a slot, and the second snap-fit ​​structure and the third snap-fit ​​structure are both snap-fit ​​parts;

[0011] Alternatively, the first snap-fit ​​structure may be a snap-fit ​​part, and the second snap-fit ​​structure and the third snap-fit ​​structure may both be snap-fit ​​slots.

[0012] Optionally, the base is provided with an air inlet, which is connected to the atomizing component.

[0013] Optionally, the atomizing mechanism further includes a third seal, the atomizing assembly includes a tubular body, and the third seal is disposed between the housing and the tubular body to seal the tubular body and the housing.

[0014] Optionally, the third sealing element is provided with an airflow channel, one end of the tubular body is inserted into the airflow channel, and the tubular body is connected to the airflow channel.

[0015] Optionally, the atomizing mechanism further includes a fourth seal disposed between the base and the atomizing assembly.

[0016] To solve the above-mentioned technical problems, another technical solution adopted by this utility model is to provide an aerosol generating device, including the above-mentioned atomizing mechanism.

[0017] In this embodiment of the present invention, when the atomizing mechanism is not used and is left unused for a long time, the base is in the first position, and the first sealing member is located between the outer shell and the atomizing component to seal the liquid storage chamber. The liquid matrix in the liquid storage chamber is prevented from entering the liquid guide port, thereby disconnecting the fluid communication between the atomizing component and the liquid storage chamber and preventing the liquid matrix from easily leaking.

The atomizing mechanism 100 includes a housing 1, an atomizing component 2, a base 3, and a sealing component 4. Specifically, the housing 1 defines a liquid storage chamber 11 for storing a liquid matrix. The atomizing component 2 is disposed inside the housing 1 and has a liquid guide port 211 for the liquid matrix to enter. The base 3 is connected to the atomizing component 2. The sealing component 4 includes a first sealing element 41 and a second sealing element 42, which are spaced apart from each other on the atomizing component 2. The first sealing element 41 and the second sealing element 42 are located on both sides of the liquid guide port 211. In other words, the liquid guide port 211 is located between the first sealing element 41 and the second sealing element 42. Between the seals 42, the second seal 42 is closer to the base 3 than the first seal 41. The base 3 can move the atomizing assembly 2 relative to the outer casing 1 between a first position and a second position. When the base 3 is in the first position, the first seal 41 is located between the outer casing 1 and the atomizing assembly 2 to seal the liquid storage chamber 11, preventing the liquid matrix from entering the liquid inlet 211. When the base 3 is in the second position, the second seal 42 is located between the outer casing 1 and the atomizing assembly 2 to seal the liquid storage chamber 11, allowing the liquid matrix to enter the liquid inlet 211. When the atomizing mechanism 100 is not used and is left unused for a long time, the base 3 is in the first position, and the first seal 41 is located between the outer casing 1 and the atomizing assembly 2 to seal the liquid storage chamber 11. The liquid matrix in the liquid storage chamber 11 is prevented from entering the liquid inlet 211, thereby disconnecting the fluid communication between the atomizing assembly 2 and the liquid storage chamber 11 and preventing easy leakage of the liquid matrix.

[0034] In some embodiments, please refer to the figure. Figure 3The outer casing 1 is provided with a through hole 12, which connects to the liquid storage chamber 11. The first seal 41 or the second seal 42 seals the gap between the side wall of the through hole 12 and the atomizing component 2. Specifically, when the base 3 is in the first position, the first seal 41 seals the gap between the side wall of the through hole 12 and the atomizing component 2; when the base 3 is in the second position, the second seal 42 seals the gap between the side wall of the through hole 12 and the atomizing component 2, while the first seal 41 is located inside the liquid storage chamber 11.

[0035] In some embodiments, please refer to Figure 4 The atomizing component 2 includes a tubular body 21, which is hollow. The tubular body 21 is provided with the aforementioned liquid guide port 211, a first mounting groove 212, and a second mounting groove 213. The first mounting groove 212 and the second mounting groove 213 are spaced apart. The liquid guide port 211 is located between the first mounting groove 212 and the second mounting groove 213. A first sealing member 41 is received in the first mounting groove 212, and a portion of the first sealing member 41 protrudes from the first mounting groove 212 so that a portion of the first sealing member 41 is used to abut against the side wall of the through hole 12. A second sealing member 42 is received in the second mounting groove 213, and a portion of the second sealing member 42 protrudes from the second mounting groove 213 so that a portion of the second sealing member 42 is used to abut against the side wall of the through hole 12.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 The atomizing mechanism 100 also includes a third seal 5, which is disposed between the housing 1 and the tubular body 21 to seal the tubular body 21 and the housing 1. The third seal 5 defines a portion of the boundary of the liquid storage chamber 11.

Furthermore, the outer shell 1 is provided with a suction nozzle 13, which is connected to the airflow channel 51.

[0038] It is understood that in some embodiments, when the base 3 is in the second position, the tubular body 21 is connected to the nozzle 13, so that the airflow flows from the tubular body 21 to the nozzle 13 without passing through the airflow channel 51.

[0039] In some embodiments, please refer to Figure 4The atomizing component 2 also includes an external liquid guide 22, an atomizing support 23, an internal liquid guide 24, and a heating element 25.

The heating element 25 is attached to the internal liquid guide 24. The atomizing support 23 is provided with a liquid passage hole 231. The external liquid guide 22 draws the liquid matrix from the liquid storage chamber 11 through the liquid guide port 211, while the internal liquid guide 24 communicates with the external liquid guide 22 through the liquid passage hole 231. Thus, the external liquid guide 22 can transfer the liquid matrix to the internal liquid guide 24 through its internal microporous structure. The internal liquid guide 24 further transfers the liquid matrix to the heating element 25, and the heating element 25 can atomize the liquid matrix to generate an aerosol.
