[0026] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0027] An embodiment of the present application discloses an atomization assembly, which is applied in an aerosol generating device to heat an aerosol generating substrate to generate an aerosol.

[0028] Please refer to Figures 1 to 3 The atomizer assembly of the embodiment of the present application protects the atomizer body, the rotating member 5 and the elastic reset member 6. The atomizer body has a liquid storage chamber 132 for storing a liquid aerosol generating matrix. The atomizer body is provided with an injection hole 111 and an exhaust hole 112 which are connected to the liquid storage chamber 132; the rotating member 5 is rotatably assembled on the atomizer body, and the rotating member 5 has a first blocking member 51 and a second blocking member 52. The rotating member 5 has a first state and a second state during its rotation; in the first state, the first blocking member 51 blocks the injection hole 111, and the second blocking member 52 blocks the exhaust hole 112; in the second state, the injection hole 111 and the exhaust hole 112 are both in an open state, and the liquid storage chamber 132 can be connected to the external space of the atomizer body through the injection hole 111 and the exhaust hole 112 respectively.

[0029] The elastic return member 6 is located between the atomizing body and the rotating member 5. The elastic return member 6 applies an elastic force to the rotating member 5 to rotate the rotating member 5 from the second state to the first state and maintain it in the first state. In this way, when liquid replenishment is needed in the liquid storage chamber 132, the user can apply an external force to the rotating member 5 to overcome the elastic force, thereby driving the rotating member 5 to rotate from the first state to the second state, which is convenient for the user to inject liquid into the injection hole 111; in addition, after the injection is completed, the elastic force applied by the elastic return member 6 to the rotating member 5 can drive the rotating member 5 to rotate from the second state to the first state, so as to close the injection hole 111 and the exhaust hole 112, and keep the injection hole 111 and the exhaust hole 112 in a closed or blocked state, so that the injection hole 111 and the exhaust hole 112 can be blocked after the injection is completed without the need for user operation, and oil leakage from the injection hole 111 due to improper operation of the operator can be avoided.

[0030] In some embodiments, the rotating member 5 is located outside the liquid storage chamber 132 as a whole, or can also be located inside the liquid storage chamber 132 as a whole, the injection hole 111 and the exhaust hole 112 are arranged at intervals, the first blocking member 51 and the second blocking member 52 are connected by a connecting member 53, the connecting member 53 is rotatably assembled on the atomizing body, and the first blocking member 51 and the second blocking member 52 can both be located on the same side of the rotation axis of the connecting member 53; the elastic reset member 6 and the first blocking member 51 can be arranged on both sides of the rotation axis of the connecting member 53, respectively, and the elastic reset member 6 is in a compressed state; or the elastic reset member 6 and the first blocking member 51 can also be arranged on the same side of the rotation axis of the connecting member 53, and the elastic reset member 6 is in a stretched state. During the rotation of the connecting member 53, the first blocking member 51 can block the injection hole 111 while the second blocking member 52 blocks the exhaust hole 112, and the injection hole 111 and the exhaust hole 112 can also be opened at the same time.

[0031] In the embodiment where the rotating member 5 is entirely located outside the liquid storage chamber 132, when the rotating member 5 is in the second state, the first sealing member 51 and the second sealing member 52 are both located outside the liquid storage chamber 132; in the embodiment where the rotating member 5 is entirely located inside the liquid storage chamber 132, when the rotating member 5 is in the second state, the first sealing member 51 and the second sealing member 52 are both located inside the liquid storage chamber 132.

[0032] For some examples, please refer to Figure 2 and Figure 3 The connecting member 53 is rotatably assembled on the atomizing body, and the connecting member 53 can be located inside the liquid storage chamber 132 or outside the liquid storage chamber 132; the first blocking member 51 and the second blocking member 52 are located on both sides of the rotation axis of the rotating member 5, and the elastic reset member 6 can be located on the same side of the rotation axis as the first blocking member 51, and can also be located on the same side of the rotation axis as the second blocking member 52.

[0033] In one embodiment, in the second state, one of the first sealing member 51 and the second sealing member 52 is located inside the liquid storage chamber 132, and the other is located outside the liquid storage chamber 132. In this way, when the liquid storage chamber 132 is under negative pressure or high pressure, the forces exerted on the two sealing members by the negative pressure or high pressure can be in opposite directions. This can avoid the influence of the pressure difference between the inside and outside of the liquid storage chamber 132 on the sealing performance of the injection hole 111 and the exhaust hole 112, which helps to ensure the sealing performance of the entire liquid storage chamber 132, thereby avoiding oil leakage from the liquid storage chamber 132.

[0034] Specifically, the first blocking member 51 and the second blocking member 52 are separately arranged. For example, the first blocking member 51 and the connecting member 53 can be integrally formed, and the second blocking member 52 is connected to the connecting member 53 by means of a threaded connection or a snap connection. Of course, the first blocking member 51 and the connecting member 53 can also be threaded or snap-connected, and the second blocking member 52 and the connecting member 53 can be integrally formed. This facilitates the installation of the rotating member 5 in the atomization assembly.

[0035] As an example, please refer to Figure 2 The connecting member 53 is located in the liquid storage chamber 132. When the rotating member 5 is in the second state, the first blocking member 51 is located in the liquid storage chamber 132, and the second blocking member 52 is located outside the liquid storage chamber 132. The first blocking member 51 can be sealed with the hole wall of the injection hole 111 in a peripheral sealing manner. For example, the outer peripheral surface of the first blocking member 51 and the hole wall of the injection hole 111 can be sealed with a sealing ring, or the first blocking member 51 can be made of rubber material, and the outer peripheral surface of the first blocking member 51 can be directly sealed with the outer peripheral surface of the first blocking member 51. The hole wall of the injection hole 111 is sealed; the second blocking member 52 can be sealed with the hole end face of the exhaust hole 112 in an end face sealing manner, such as the second blocking member 52 has a sealing end face 521 facing the atomizing body, and the sealing end face 521 can be sealed with the hole end face of the exhaust hole 112 by a sealing ring installed on the periphery of the exhaust hole 112, or the second blocking member 52 can be made of rubber material, and the sealing end face 521 on the second blocking member 52 can be directly sealed with the hole end face of the exhaust hole 112. Of course, if the first blocking member 51 and the hole end face of the injection hole 111 are sealed with the end face, and the outer peripheral surface of the second blocking member 52 and the hole wall of the exhaust hole 112 are sealed with the peripheral surface, it is also possible.

[0036] The above-mentioned structure in which the first blocking member 51 is located inside the liquid storage cavity 132 and the second blocking member 52 is located outside the liquid storage cavity 132 in the second state can allow the user to operate the bottle mouth of the liquid injection bottle to push the first blocking member 51 when it is necessary to add liquid aerosol generating matrix to the liquid storage cavity 132, so that the liquid injection hole 111 and the exhaust hole 112 can be opened at the same time, without the need to open the liquid injection hole 111 separately, which facilitates the opening of the liquid injection hole 111. In addition, the first blocking member 51 and the liquid injection hole 111 are sealed on the outer peripheral surface, which facilitates the bottle mouth of the liquid injection bottle to extend into the liquid storage cavity 132 after pushing the blocking member, and can reduce the liquid aerosol generating matrix remaining on the end surface of the first blocking member 51 facing away from the liquid storage cavity 132.

[0037] In another example, when the rotating member 5 is in the second state, the first sealing member 51 is located outside the liquid storage chamber 132, and the second sealing member 52 is located inside the liquid storage chamber 132. Both the first sealing member 51 and the second sealing member 52 can adopt end face sealing and circumferential surface sealing to achieve sealing with the corresponding injection hole 111 and exhaust hole 112, thereby achieving the sealing of the injection hole 111 and the exhaust hole 112.

[0038] In one embodiment, please continue to refer to Figure 2 and Figure 3 The elastic reset member 6 includes a spring, which may be located in the liquid storage chamber 132 or outside the liquid storage chamber 132. In one example, the spring may be a tension spring, one end of which is connected to the atomizing body and the other end is connected to the rotating member 5; in another example, please adopt the consideration Figure 2 The spring can also be a compression spring, one end of the spring abuts against the atomizing body, and the other end abuts against the rotating member 5; the other end of the spring can apply an elastic force to the rotating member 5 to rotate the rotating member 5 toward the first state and maintain it in the first state.

[0039] For further information, please refer to Figure 2 and Figure 3 In some embodiments, the first blocking member 51 and the second blocking member 52 are arranged at both ends of the connecting member 53 in the extension direction thereof. The connecting member 53 has a first connecting end 55 and a second connecting end 56 arranged along the extension direction thereof. The first blocking member 51 can be directly connected to the first connecting end 55, and the second blocking member 52 can be connected to the second connecting end 56 through a connecting arm 57. The first blocking member 51 is generally a cylindrical structure, and the first blocking member 51 has an outer peripheral surface that matches the hole wall surface of the injection hole 111. The second blocking member 52 can be a plate-like structure, and the connecting arm 57 is a rod-like structure. The end face of the second blocking member 52 facing the exhaust hole 112 is a sealing end face 521 that seals with the hole end face of the exhaust hole 112.

[0040] The elastic reset member 6 connected to or abutting the rotating member 5 can directly act on the first connection end 55 and / or the second connection end 56 of the connecting member 53, which can reduce the risk of poor sealing between the first blocking member 51 and the injection hole 111 and the second blocking member 52 and the exhaust hole 112 due to deformation of the rotating member 5 to a certain extent. In one example, there is one elastic reset member 6, and the elastic reset member 6 can act on the first connection end 55 or the second connection end 56; in other examples, there are multiple elastic reset members 6, one of which acts on the first connection end 55, and the other elastic reset member 6 acts on the second connection end 56, or both elastic reset members 6 can act on the same connection end.

[0041] Or in other embodiments, in a structure where the rotating member 5 is not easily deformed, an elastic reset member 6 may be further provided to act on a position of the rotating member 5 close to its rotation axis.

[0042] In one embodiment, please adopt the consideration Figure 2 The connecting member 53 can be a plate-like structure facing the vertical injection hole 111, and the first blocking member 51 is connected to one side of the plate-like structure. The connecting member 53 is provided with a guide column 511 extending in the direction of the vertical connecting plate, and the guide column 511 can be arranged at the action end of the elastic reset member 6, such as the guide column 511 can be located at the first connecting end 55, and the guide column 511 and the first blocking member 51 are respectively arranged on both sides of the connecting member 53, and the elastic reset member 6 is a spring, which is sleeved on the guide column 511, and the guide column 511 can provide guidance for the elastic deformation of the spring, which helps to extend the service life of the spring.

[0043] In other embodiments, the elastic reset member 6 may also be a rubber member with good elastic deformation ability. The rubber member may be arranged into a sleeve structure. The rubber member may be sleeved on the guide column 511 , and the guide column 511 provides guidance for the elastic deformation of the rubber member.

[0044] In one embodiment, please refer to Figure 2 and Figure 3 The atomizer body includes an atomizer shell 1 and an atomizer tube 2 sealed with the atomizer shell 1. The atomizer shell 1 includes an atomizer shell 11, an atomizer nozzle 12 and an atomizer base 13. The atomizer shell 11 and the atomizer base 13 are sealed to enclose a receiving cavity. The injection hole 111 and the exhaust hole 112 are both located on the atomizer shell 11 and are connected to the receiving cavity. The atomizer nozzle 12 is connected to the atomizer shell 11 by a snap or by a thread. The atomizer nozzle 12 can cover the injection hole 111 and the exhaust hole 112 to avoid the injection hole 111 and the exhaust hole 112 being exposed. Before replenishing the liquid aerosol generating matrix into the liquid storage cavity 132, the atomizer nozzle 12 needs to be disassembled first.

[0045] In one embodiment, please continue to refer to Figure 2 and Figure 3 , the atomizing base 13 is sealed with the atomizing housing 11 through the sealing member 14, the atomizing tube 2 is located in the atomizing housing 11, the atomizing tube 2 passes through the atomizing housing 11 and the sealing member 14, one end of the atomizing tube 2 in its extension direction is sealed with the atomizing housing 11, and the other end is sealed with the sealing member 14, the atomizing tube 2, the atomizing housing 11 and the sealing member 14 enclose a liquid storage chamber 132 surrounding the atomizing tube 2. The atomizing body has an atomizing channel 22 located in the atomizing tube 2, an atomizing core is arranged in the atomizing channel 22, the atomizing core comprises an atomizing bracket 31, a first liquid absorbing member 32, a liquid storage member 33 and a heating member 34, the atomizing bracket 31 is pressed between the sealing members 14 of the atomizing tube 2, the atomizing bracket 31 extends toward the inside of the atomizing channel 22, the liquid storage member 33 is located on the radial outer side of the atomizing bracket 31, the first liquid absorbing member 32 is located on the radial inner side of the atomizing bracket 31, and the heating member 34 is located on the radial inner side of the first liquid absorbing member 32. The atomizing tube 2 has an opening connecting the liquid storage chamber 132 and the atomizing channel 22. The liquid aerosol matrix in the liquid storage chamber 132 can pass through the liquid storage component 33 and the first liquid absorption component 32 along the opening in sequence and contact the heating component 34, and be heated by the heating component 34 to generate aerosol.

[0046] The atomizer base 13 has an air inlet and an air inlet channel 131 connected to the air inlet. The air inlet channel 131 is connected to the atomization channel 22. A cavity connecting the air inlet channel 131 and the atomization channel 22 is provided between the atomizer base 13 and the sealing member 14. A second liquid absorbing member 15 is provided in the cavity. The second liquid absorbing member 15 can receive and absorb liquid dripping from the atomization channel 22 due to condensation to prevent liquid from leaking out of the air inlet of the atomizer assembly.

[0047] A connecting electrode 4 is installed on the atomizer base 13, and the heating element 34 in the atomizer core has an external wire, which can pass through the second liquid absorption component 15 and the atomizer base 13 to be conductively connected to the connecting electrode 4. The heating element 34 can be connected to an external power source through the connecting electrode 4 to power the heating element 34.

[0048] In one embodiment, please continue to refer to Figure 2 and Figure 3 , there is a through hole on the atomizing housing 11 that is connected to the atomizing channel 22, and the through hole is located between the liquid injection hole 111 and the exhaust hole 112. The first blocking member 51 and the second blocking member 52 on the rotating member 5 are arranged on both sides of the atomizing tube 2. In this way, the first blocking member 51 and the second blocking member 52 are dispersed relative to the atomizing tube 2, which helps to achieve a compact design of the rotating member 5 and the atomizing tube 2 in the liquid storage cavity 132, and helps to reduce the volume of the atomizing assembly increased by the additional rotating member 5. Of course, in other embodiments, when the shape change and volume increase of the atomizing assembly caused by the additional rotating member 5 are not considered, the first blocking member 51 and the second blocking member 52 can also be arranged to be located on the same side of the atomizing tube 2.

[0049] Furthermore, in an embodiment in which the first blocking member 51 and the second blocking member 52 are respectively arranged on both sides of the atomizer tube 2, a connecting member 53 can also be arranged to be sleeved on the atomizer tube 2, such as a through hole 531 arranged on the connecting member 53 in the extension direction of the atomizer channel 22, so that the atomizer tube 2 is located in the through hole 531, so that the atomizer tube 2 can provide pre-positioning for the installation of the connecting member 53 in the liquid storage chamber 132 through the atomizer tube 2, thereby facilitating the rotational cooperation between the connecting member 53 and the atomizer body.

[0050] In order to ensure the normal rotation of the rotating member 5, the aperture of the through hole 531 on the connecting member 53 can also be set to be larger than the outer diameter of the atomizer tube 2 located in the through hole 531, so that the connecting member 53 and the tube wall of the atomizer tube 2 are spaced apart in the radial direction of the atomizer tube 2. This can avoid interference between the rotation stroke of the atomizer tube 2 and the rotating member 5, can meet the requirement that the rotating member 5 has a larger rotation stroke, and help ensure that the bottle mouth of the injection bottle extends into the liquid storage chamber 132.

[0051] In some embodiments, the rotating member 5 is rotatably assembled on the atomizing body. In the embodiment where the rotation axis is located at the connecting member 53, the connecting member 53 can be rotatably assembled on the atomizing housing 1 through the pin 54.
