Description

Atomizer and aerosol generating device capable of realizing liquid-core separation

This application claims the priority of 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

The present application relates to the field of aerosol generating devices, and in particular to an atomizer and an aerosol generating device capable of realizing liquid-core separation.

Background Art

An aerosol generating device is an electronic product that utilizes an atomizing component to heat and atomize an aerosol matrix into an aerosol state 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 the related art, 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 the related art 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 continue to contact with the atomizing component. When the aerosol generating device is not in use, the aerosol matrix will continue to 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.

(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-passing 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 user 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.

(2) The liquid partition member in the atomizer provided in the embodiment of the present application is snapped onto 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 through 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 through 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 through 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 atomizer assembly, thereby realizing the separation of the aerosol matrix and the atomizer assembly, that is, realizing the liquid core separation, 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.

Example 1

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, in which an atomizer assembly 40 that can slide relative to the liquid storage tank 1 is arranged, 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.

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 atomization component 40 can move in the liquid storage tank 1, and the liquid partition member 2 is clamped on the atomization component 40 and can move with the atomization component 40. When the atomization component 40 drives the liquid partition member 2 to move and the liquid through hole 21 is 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 atomization component 40 in sequence. 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 liquid core separation, 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.

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 arranged in the atomizer tube 5, and an atomizer core 52 arranged 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.

Specifically, a base 11 is provided at the bottom of the liquid storage tank 1, a fixed component 60 is provided at the top of the liquid storage tank 1, and the suction nozzle 4 is arranged 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.

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 buckled 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 buckled with the locking member 6, thereby realizing the installation of the atomizing assembly 40.

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

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

Specifically, a slot 53 is provided on the atomizer tube 5, and a buckle 22 is provided on the liquid barrier member 2. The buckle 22 engages with the slot 53 so that the atomizer tube 5 drives the liquid barrier member 2 to move. The buckle 22 engages with the slot 53 so that the liquid barrier member 2 and the atomizer tube 5 are connected together, thereby ensuring that when the atomizer tube 5 moves up and down, it drives the liquid barrier member 2 to move up and down, thereby realizing the connection or closure between the liquid passage hole 21 and the liquid inlet hole 31.

Specifically, a limiting groove 32 is provided between the fixing member 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. Therefore, when the atomization assembly 40 is moved out of the liquid storage tank 1, the liquid isolation member 2 is prevented from being taken out, thereby ensuring that the liquid isolation member 2 is always in the liquid isolation tube 3.

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 member 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, and the atomizer tube 5 ensures that when the atomizer tube 5 moves up and down, it drives the liquid partition member 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 member 2 to move upward.

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 atomizer core 52 is electrically connected to the battery core 7. The battery core 7 is used to supply power to the atomizer core 52, so that the atomizer core 52 can generate heat to heat the aerosol matrix stored in the inner package 51 and atomize it into a mist-like aerosol.

Specifically, the shell 70 includes an outer shell 71 and a bottom cover 72 arranged at the lower end of the outer shell 71. The battery cell is arranged in the outer shell 71. A bracket 73 is arranged in the outer shell 71. An electrode 74 is arranged 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, so as to realize the electrical connection between the atomizer core 52 and the battery cell 7.
