[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 8, 2023, with application number 202322122554.6 and invention name “A Aerosol Generating Device Capable of Realizing Liquid Core Separation”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of aerosol generating devices, and in particular to an atomizer and an aerosol generating device capable of achieving liquid-core separation. Background Art

[0003] An aerosol generating device is an electronic product that utilizes an atomizing component to heat and atomize an aerosol matrix into an aerosol form for use by users. At the same time, the aerosol generated by the aerosol generating device does not contain other harmful components such as tar and suspended particulates. Therefore, it has a wide application market. In related technologies, after the aerosol generating device is assembled, in order to avoid leakage of the aerosol matrix, a liquid core separation form is generally required. However, the liquid core separation of the aerosol generating device in related technologies can only achieve liquid core separation before the first use. After the electronic cigarette is used for the first time, the liquid core separation form will be destroyed, and the aerosol matrix will always be in contact with the atomizing component. When the aerosol generating device is not in use, the aerosol matrix is ​​always in contact with the atomizing component, which is not conducive to the storage and transportation of the aerosol generating device, and will also cause a bad experience for the user when it is used again.

[0005] In the second aspect, the present application provides a nebulizer for the above-mentioned aerosol generating device, the nebulizer includes a liquid storage tank, an atomizer assembly slidable relative to the liquid storage tank is arranged in the liquid storage tank, wherein the atomizer assembly is outer-circuited with a liquid partition, the liquid partition is outer-circuited with a liquid partition tube, the liquid partition tube is provided with a liquid inlet hole, the liquid partition is provided with a liquid through hole, the liquid partition tube is fixed in the liquid storage tank, the liquid partition is clamped on the atomizer assembly and can move with the atomizer assembly to connect or close the liquid through hole with the liquid inlet hole.

[0006] The aerosol generating device and atomizer capable of achieving liquid-core separation provided in this application have the following beneficial effects:

[0007] (1) The liquid partition member in the aerosol generating device capable of realizing liquid-core separation provided in the embodiment of the present application is clamped on the atomizing assembly and can move with the atomizing assembly. When the atomizing assembly drives the liquid partition member to move and connects the liquid-passing hole with the liquid-inlet hole, the aerosol matrix stored in the liquid storage tank can flow through the liquid-inlet hole and the liquid-passing hole in sequence and flow to the atomizing assembly located in the liquid partition member. The atomizing assembly can heat the aerosol matrix and atomize it into a mist-like aerosol for the user to use. When the atomizing assembly drives the liquid partition member to move and closes the liquid-passing hole and the liquid-inlet hole, the aerosol matrix stored in the liquid storage tank flows to the liquid-inlet hole and stops. If it does not flow into the liquid partition member, it will not flow to the atomizing assembly, thereby realizing the separation of the aerosol matrix and the atomizing assembly, that is, realizing the liquid-core separation, avoiding the aerosol matrix from being in contact with the atomizing assembly when the aerosol generating device is not in use, thereby facilitating the storage and transportation of the aerosol generating device.

[0008] (2) The liquid partition member in the atomizer provided in the embodiment of the present application is clamped on the atomizer assembly and can move with the atomizer assembly. When the atomizer assembly drives the liquid partition member to move and connects the liquid hole with the liquid inlet hole, the aerosol matrix stored in the liquid storage tank can flow through the liquid inlet hole and the liquid hole in sequence and flow to the atomizer assembly located in the liquid partition member. The atomizer assembly can heat the aerosol matrix and atomize it into a mist-like aerosol for the user to use. When the atomizer assembly drives the liquid partition member to move and closes the liquid hole and the liquid inlet hole, the aerosol matrix stored in the liquid storage tank stops flowing to the liquid inlet hole and will not flow into the liquid partition member and will not flow to the atomizer assembly, thereby realizing the separation of the aerosol matrix and the atomizer assembly, that is, realizing the separation of the liquid core, avoiding the aerosol matrix from being in contact with the atomizer assembly when the atomizer is not in use, thereby facilitating the storage and transportation of the atomizer.

[0021] Example 1

[0022] Please refer to Figures 1-7. The aerosol generating device that can achieve liquid-core separation provided in this embodiment includes a liquid storage tank 1, and an atomizer assembly 40 that can slide relative to the liquid storage tank 1 is arranged in the liquid storage tank 1, wherein a liquid partition member 2 is provided on the outer sleeve of the atomizer assembly 40, a liquid partition tube 3 is provided on the outer sleeve of the liquid partition member 2, a liquid inlet hole 31 is provided on the liquid partition tube 3, and a liquid through hole 21 is provided on the liquid partition member 2. The liquid partition tube 3 is fixed in the liquid storage tank 1, and the liquid partition member 2 is clamped on the atomizer assembly 40 and can move with the atomizer assembly 40 to connect or close the liquid through hole 21 with the liquid inlet hole 31.

[0023] Through the above structure, in actual application, the aerosol generating device that can realize liquid core separation according to the embodiment of the present application is adopted, and the liquid storage tank 1 is used to store the aerosol matrix. The aerosol matrix stored in the liquid storage tank 1 can flow to the liquid inlet hole 31, and the atomizing component 40 can move in the liquid storage tank 1, and the liquid partition 2 is clamped on the atomizing component 40 and can move with the atomizing component 40. When the atomizing component 40 drives the liquid partition 2 to move and makes the liquid hole 21 connected to the liquid inlet hole 31, the aerosol matrix stored in the liquid storage tank 1 can flow through the liquid inlet hole 31 and The liquid passes through the liquid hole 21 and flows to the atomizing assembly 40 located in the liquid partition 2. The atomizing assembly 40 can heat the aerosol matrix and atomize it into a mist-like aerosol for the user to use. When the atomizing assembly 40 drives the liquid partition 2 to move and closes the liquid passing hole 21 and the liquid inlet hole 31, the aerosol matrix stored in the liquid storage tank 1 flows to the liquid inlet hole 31 and stops. If it does not flow into the liquid partition 2, it will not flow to the atomizing assembly 40, thereby realizing the separation of the aerosol matrix and the atomizing assembly 40, that is, realizing the separation of the liquid core, avoiding the aerosol matrix from being in contact with the atomizing assembly 40 when the aerosol generating device is not in use, thereby facilitating the storage and transportation of the aerosol generating device.

[0024] Specifically, the atomizer assembly 40 includes a nozzle 4, an atomizer tube 5 connected to the lower end of the nozzle 4, an inner package 51 provided in the atomizer tube 5, and an atomizer core 52 provided in the inner package 51. The inner package 51 is used to adsorb and store the aerosol matrix flowing into the atomizer tube 5, and the atomizer core 52 is used to heat the aerosol matrix adsorbed in the inner package 51 and atomize it into a mist-like aerosol. The aerosol can flow along the atomizer tube 5 to the nozzle 4 to be used by the user.

[0025] Specifically, a base 11 is provided at the bottom of the liquid storage tank 1, and a fixed component 60 is provided at the top of the liquid storage tank 1. The suction nozzle 4 is provided in the fixed component 60. The base 11 is used for sealing the bottom of the liquid storage tank 1 and installing the atomization component 40. The fixed component 60 is used for installing the suction nozzle 4. The suction nozzle 4 can move up and down in the fixed component 60 to drive the atomization tube 5 to move up and down in the liquid storage tank 1, thereby driving the liquid partition 2 to move up and down relative to the liquid partition tube 3.

[0026] Specifically, a locking member 6 is provided in the fixing assembly 60, and a locking buckle 41 is provided on the atomizing assembly 40. The locking buckle 41 is engaged with the locking member 6 to fix the atomizing assembly 40 on the fixing assembly 60. When installing the atomizing assembly 40, the atomizing assembly 40 is inserted from the upper end of the liquid storage tank 1, and the locking buckle 41 is engaged with the locking member 6, thereby realizing the installation of the atomizing assembly 40.

[0027] Specifically, the fixing assembly 60 includes a base 61 provided at the top of the liquid storage tank 1, a top cover 62 provided at the upper end of the base 61, and a fixing member 63 provided on the outside of the suction nozzle 4. The locking member 6 is provided between the base 61 and the top cover 62. The base 61 cover is provided at the upper end of the liquid storage tank 1. The locking member 6 is fixed between the base 61 and the top cover 62 and is fixed by the fixing member 63. The fixing member 63 can also provide a guide for the installation of the atomization assembly 40.

[0028] Specifically, a sealing gasket 64 is further provided on the base 61 , and the sealing gasket 64 provides a seal for the top of the liquid storage tank 1 , further ensuring that the aerosol matrix in the liquid storage tank 1 does not leak.

[0029] Specifically, a slot 53 is provided on the atomizing tube 5, and a buckle 22 is provided on the liquid partition 2. The buckle 22 engages with the slot 53 so that the atomizing tube 5 drives the liquid partition 2 to move. The buckle 22 engages with the slot 53 so that the liquid partition 2 and the atomizing tube 5 are connected together, thereby ensuring that when the atomizing tube 5 moves up and down, the liquid partition 2 is driven to move up and down, thereby realizing the connection or closure between the liquid hole 21 and the liquid inlet hole 31.

[0030] Specifically, a limiting groove 32 is provided between the fixing part 63 and the liquid isolation tube 3. After the buckle 22 moves into the limiting groove 32, the buckle 22 is separated from the slot 53. The limiting groove 32 can limit the movement of the buckle 22. When the buckle 22 moves into the limiting groove 32, the buckle 22 is separated from the slot 53, so that when the atomization assembly 40 is moved out of the liquid storage tank 1, the liquid isolation part 2 is prevented from being taken out, thereby ensuring that the liquid isolation part 2 is always in the liquid isolation tube 3.

[0031] Specifically, the buckle 22 is a T-shaped buckle. When the atomizer assembly 40 moves downward, since the buckle 22 is T-shaped, the buckle 22 tilts toward the axis of the liquid partition part 2 under the force of the inner wall of the liquid partition tube 3, so that the buckle 22 can be engaged with the limiting groove 32. The atomizer tube 5 ensures that when the atomizer tube 5 moves up and down, it drives the liquid partition part 2 to move up and down. After the buckle 22 moves into the limiting groove 32, the force of the inner wall of the liquid partition tube 3 on the buckle 22 disappears, and the buckle 22 will recover and no longer tilt. At this time, the buckle 22 will be separated from the slot 53, and when the atomizer tube 5 continues to move upward, it will not drive the liquid partition part 2 to move up.

[0032] Specifically, a shell 70 is provided at the lower end of the liquid storage tank 1, and a battery core 7 is provided in the shell 70. The atomizing core 52 is electrically connected to the battery core 7. The battery core 7 is used to power the atomizing core 52, so that the atomizing core 52 can generate heat to heat the aerosol matrix stored in the inner package 51 and atomize it into a mist-like aerosol.

[0033] Specifically, the shell 70 includes an outer shell 71 and a bottom cover 72 provided at the lower end of the outer shell 71. The battery cell is provided in the outer shell 71. A bracket 73 is provided in the outer shell 71. An electrode 74 is provided on the bracket 73. The electrode 74 is electrically connected to the battery cell 7 and the atomizer core 52. The electrode 74 is a connecting conductor between the battery cell 7 and the atomizer core 52, thereby realizing electrical connection between the atomizer core 52 and the battery cell 7.
