Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generating devices, in particular to an aerosol generating device and an atomizer component and an atomizer thereof. Background Art

[0002] The aerosol generating device is used to generate aerosol for the user to inhale. There are many types of aerosol generating devices, including at least contact heating type, non-contact heating type and vibration atomization type. In the contact heating type aerosol generating device, the aerosol generating substrate flows to the surface of the electric heating element, and the electric heating element is used to heat and atomize the aerosol generating substrate to generate an aerosol.

[0003] An aerosol generating device using an aerosol generating substrate generally includes an atomizer and a power source, wherein the atomizer includes a housing, a liquid storage chamber, and an atomizing assembly, wherein the liquid storage chamber is in fluid communication with the atomizing assembly, and the aerosol generating substrate is supplied from the liquid storage chamber into the atomizing assembly, so that the aerosol generating substrate is electrically heated by the atomizing assembly and atomized by heat. In order to be able to replenish the aerosol generating substrate into the liquid storage chamber and extend the use time, a common solution of the current aerosol generating device is that an oil filling hole connected to the liquid storage chamber is provided on the housing of the atomizer, and a removable sealing plug is provided at the oil filling hole. When replenishing the liquid storage chamber with oil, after a large amount of aerosol generating substrate in the liquid replenishing device enters the liquid storage chamber, the gas in the liquid storage chamber cannot be emptied in time, thereby causing the aerosol generating substrate to easily overflow from the oil filling hole.

[0062] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0063] 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).

[0064] When replenishing oil into the liquid storage chamber of the atomizer, in order to avoid over-replenishing of oil, the present application adopts a first liquid guiding component to connect the liquid replenishing device and the liquid storage chamber, and a slow release element is arranged in the liquid guiding channel of the first liquid guiding component. The slow release element can slowly release the aerosol generating matrix, so that the aerosol generating matrix slows down entering the liquid storage chamber.

[0065] In one embodiment, please refer to Figures 1 to 4 The aerosol generating device includes an atomizer, a liquid replenishing device 6 and a power supply 103, and the power supply 103 supplies power to the atomizer. In one embodiment, the atomizer and the power supply 103 are integrated together. In some other embodiments, as an alternative, the atomizer and the power supply 103 can be designed independently. In this case, the power supply 103 includes a power box and a battery configured in the power box. The power box and the atomizer are fixed together by magnetic attraction, snap buckle, etc., so that the atomizer and the power supply 103 can be easily disassembled.

[0066] In one embodiment, please refer to Figures 1 to 4The atomizer includes a housing 1, a capillary liquid storage element 2, an atomizing component 3, a first liquid guide component and a slow release component 4, wherein the housing 1 has a liquid storage chamber 11 and an air flow channel 13, and the capillary liquid storage element 2 is arranged in the liquid storage chamber 11 to store the aerosol generating matrix. The capillary liquid storage element 2 can be made of any feasible porous material, such as oil storage cotton, porous ceramic blocks, etc.

[0067] The atomizing assembly 3 is in fluid communication with the liquid storage chamber 11, so that the aerosol-generating substrate in the liquid storage chamber 11 is transferred from the capillary liquid storage element 2 to the atomizing assembly 3. The atomizing assembly 3 includes an electric heating element 31 for heating and atomizing the aerosol-generating substrate, and at least part of the electric heating element 31 is disposed in the air flow channel 13. The electric heating element 31 can heat and atomize the aerosol-generating substrate entering the atomizing assembly 3 for the user to inhale.

[0068] In one embodiment, the atomization assembly 3 includes an electric heating element 31, which is a spiral heating wire extending along the air flow channel 13. The outer peripheral surface of the electric heating element 31 is covered with a layer of liquid-conducting cotton. The outer peripheral surface of the liquid-conducting cotton is in direct contact with the capillary liquid storage element 2, thereby absorbing and transferring the aerosol-generating matrix to the electric heating element 31.

[0069] In one embodiment, the electric heating element 31 is a conductive mesh (conductive metal mesh), which is a hollow columnar mesh. Compared with a spiral heating wire, the electric heating element 31 generates heat more evenly and can easily increase the amount of atomization.

[0070] In one embodiment, the outer peripheral surface of the electric heating element 31 can also be replaced with a microporous component such as ceramics to replace the liquid-conducting cotton, such as a hollow cylindrical ceramic. The electric heating element 31 can be sintered together with the hollow cylindrical ceramic, or they can be made separately and then assembled.

[0071] In one embodiment, the atomization component is a planar mesh (not shown in the figure), one side of the planar mesh is attached to liquid-conducting cotton or liquid-conducting ceramic, the atomization component is overall plate-shaped, and is positioned in a vertical manner in the air flow channel, and there is a gap between the planar mesh and the inner wall of the air flow channel to allow air flow to pass through.

[0072] In one embodiment, the proximal end of the first liquid guiding component is in fluid communication with the capillary liquid storage element 2, and the distal end of the first liquid guiding component is used to be in fluid communication with the liquid replenishment device 6. The first liquid guiding component has a liquid guiding channel 51 that defines a liquid flow path from the liquid replenishment device 6 to the capillary liquid storage element 2, and the slow release element is positioned in the liquid guiding channel 51. The liquid guiding channel 51 is used to connect the liquid storage chamber 11 with the liquid replenishment device 6, so that the aerosol generating matrix can enter the liquid storage chamber 11 from the liquid replenishment device 6. The liquid guiding channel 51 has a liquid inlet 511 and a liquid outlet 512, and the liquid outlet 512 is connected to the liquid storage chamber 11 to replenish the liquid storage chamber 11. The liquid inlet 511 is used to communicate with the liquid replenishment device 6, so that the aerosol generating matrix in the liquid replenishment device 6 enters the liquid guiding channel 51.

[0073] Specifically, in one embodiment, the distal end of the first liquid guiding component is used to be inserted into the liquid replenishing device 6, and the liquid inlet 511 of the liquid guiding channel 51 is arranged at the distal end of the first liquid guiding component. The proximal end of the first liquid guiding component is inserted into the capillary liquid storage element 2, and the liquid outlet 512 of the liquid guiding channel 51 is arranged at the proximal end of the first liquid guiding component.

[0074] In one embodiment, the aerosol-generating matrix in the fluid replenishment device 6 enters the liquid guide channel 51, and the first liquid guide component has an insertion portion 52 for inserting into the fluid replenishment device 6, and the liquid inlet 511 is located on the insertion portion 52. In one embodiment, a sealing member 63 is provided at the bottle mouth of the fluid replenishment device 6, and the insertion portion 52 enters the fluid replenishment device 6 after passing through the sealing member 63, and the sealing member 63 can reduce or even prevent the leakage of oil. Among them, at least the rigidity of the insertion portion 52 at least satisfies that the insertion portion 52 does not produce deformation that hinders the flow of liquid after being inserted into the fluid replenishment device 6.

[0075] In one embodiment, the slow-release element 4 is filled in the liquid-conducting channel 51 to slow down the oil in the liquid-replenishing device 6 from entering the liquid storage chamber 11. The slow-release element 4 can be made of any feasible porous material, such as liquid-conducting cotton or porous ceramics. Through the buffering effect of the slow-release element 4, the aerosol-generating matrix can be slowed down from entering the liquid storage chamber 11, so that the aerosol-generating matrix is ​​not easy to enter the liquid storage chamber 11 too quickly, and the flow rate or flow of the aerosol-generating matrix can be controlled, thereby improving the leakage problem caused by the easy oversaturation of the capillary liquid storage element 2.

[0076] In one embodiment, the slow-release element 4 includes a porous plate (not shown), the holes on which form the flow holes of the aerosol-generating matrix. The porous plate can effectively limit the cross-sectional area of ​​the liquid-conducting channel 51 and slow down the flow rate.

[0077] In one embodiment, the slow-release element 4 can also be a combination of a porous plate and liquid-conducting cotton; or a combination of a porous plate and porous ceramics; or a combination of liquid-conducting cotton and porous ceramics; or a combination of the above three.

[0078] The oil replenishment operation of the refilling device can be carried out in a variety of feasible ways, such as turning the refilling device upside down or lying flat to allow the aerosol-generating matrix in the refilling device to enter the liquid guide hole; another example is that the refilling device uses a deformable material and the aerosol-generating matrix in the refilling device is squeezed into the liquid guide hole by squeezing the refilling device; another example is the shaking effect generated by the user during the carrying and suction process.

[0079] The first liquid guiding component can be implemented in a variety of feasible ways. For example, in one embodiment, please refer to Figure 1 and Figure 4 The first liquid guiding component includes a liquid guiding tube 5, and a liquid guiding channel 51 is a tube hole of the liquid guiding tube 5. The slow release element 4 is positioned in the liquid guiding tube 5. One end of the liquid guiding tube 5 is a liquid inlet end 54 for inserting into the liquid replenishing device 6, and the liquid inlet port 511 is located at the end of the liquid inlet end 54. The liquid guiding tube 5 has a simple structure and is convenient for processing and installation. For another example, in some other embodiments, in addition to using the liquid guiding tube 5, the liquid guiding channel can be opened on the cavity wall of the liquid storage cavity.

[0080] In a specific embodiment, the liquid inlet 511 is an end opening of the liquid guiding tube 5. In some other embodiments, as an alternative, the liquid inlet 511 can also be arranged on the tube side wall of the liquid guiding tube 5.

[0081] Further, in one embodiment, please refer to Figure 1 and Figure 2 , the liquid guide tube 5 includes an insertion section 55 inserted into the capillary liquid storage element 2, and the liquid outlet 512 is located on the insertion section 55. After the liquid guide tube 5 is inserted into the capillary liquid storage element 2, it is more conducive to the aerosol generating matrix flowing out from the liquid outlet 512 to enter the capillary liquid storage element 2. In order to make the aerosol generating matrix better enter the capillary liquid storage element 2, in one embodiment, the end of the insertion section 55 away from the liquid inlet 511 is a closed end 53, and the closed end is a closed structure. The liquid outlet 512 is on the side wall of the insertion section 55, and the capillary liquid storage element 2 covers the liquid outlet 512. In this way, after the aerosol generating matrix enters the liquid guide tube 5 from one end of the liquid guide tube 5, it will not leak out from the other end and directly enter the capillary liquid storage element 2.

[0082] In some other embodiments, in addition to being inserted into the capillary liquid storage element 2, the liquid guide tube 5 may not be inserted into the capillary liquid storage element 2, for example, the liquid outlet 512 is an end opening of the liquid guide tube 5, and the liquid outlet 512 is attached to the surface of the capillary liquid storage element 2. Of course, in some other embodiments, it is also feasible that there is a gap between the liquid outlet 512 and the capillary liquid storage element 2, and the aerosol generating matrix first enters the liquid storage cavity 11, and then contacts the capillary liquid storage element 2 and is adsorbed by the capillary liquid storage element 2; at this time, after entering the liquid storage cavity 11, the aerosol generating matrix can drip on the capillary liquid storage element 2 by gravity, or flow to the capillary liquid storage element 2 along the cavity wall of the liquid storage cavity 11.

[0083] In some other embodiments, in addition to adopting a structure with one end closed, the liquid catheter 5 can also be open at both ends. In this case, the liquid outlet 512 on the side wall of the liquid catheter 5 can be retained, and the opening at the end can also be used as the liquid outlet 512. In order to prevent the aerosol-generating matrix from leaking out from the end opening, the insertion section 55 is in the capillary liquid storage element 2 at this time, and the capillary liquid storage element 2 blocks all the liquid outlets 512 of the liquid catheter 5.

[0084] In one embodiment, please refer to Figure 1 and Figure 4 Since the liquid outlet 512 is located on the side wall of the insertion section 55, there are at least two liquid outlets 512, and at least two liquid outlets 512 are arranged at intervals along the extension direction of the insertion section 55. In this way, the number of liquid outlets 512 is large, and the aerosol generating matrix can enter the capillary liquid storage element 2 at multiple locations, which is conducive to rapid replenishment of the oil storage element.

[0085] For details, please refer to Figure 3 and Figure 4 The number of the liquid outlets 512 is three groups, with four in each group, and the four liquid outlets 512 in the same group are evenly distributed in the circumferential direction of the liquid guiding tube 5 .

[0086] The slow-release element 4 can have a variety of feasible arrangements. In one embodiment, the slow-release element 4 blocks the liquid outlet 512, so that the aerosol-generating matrix can be quickly adsorbed by the capillary liquid storage element 2 after leaving the slow-release element 4. Figure 1 and Figure 2 , the slow-release element 4 fills the catheter 5. In some other embodiments, the number of the slow-release elements 4 can be multiple, and it is selected whether to set intervals between adjacent slow-release elements 4 as needed. In some other embodiments, the slow-release element 4 is only filled in the insertion section 55 of the catheter 5.

[0087] Further, in one embodiment, please refer to Figure 1 and Figure 2 , the atomizing assembly 3 and the liquid guiding tube 5 are arranged at intervals, the extension direction of the airflow channel 13 is consistent with the extension direction of the liquid guiding tube 5, and the airflow channel 13 and the liquid guiding tube 5 are arranged side by side along the width direction of the atomizer. Such an arrangement structure is more compact, and the aerosol generating matrix in the liquid guiding tube 5 can reach the atomizing assembly 3 faster. In some other embodiments, in addition to the above arrangement, the atomizing assembly 3 and the liquid guiding tube 5 can also be arranged in any other feasible manner, such as the airflow channel 13 of the atomizing assembly 3 extending in a direction perpendicular to the extension direction of the liquid guiding tube 5.

[0088] Further, in one embodiment, please refer to Figure 1 and Figure 2 The housing 1 has an installation space 12 for installing the fluid infusion device, and the first fluid guiding component is at least partially located in the installation space 12.

[0089] The nebulizer also includes a removable element, which is configured to close the first liquid guiding component, and at least part of the removable element can be removed from the first liquid guiding component, so that the first liquid guiding component is in a liquid inlet closed state and a liquid inlet open state, respectively. When the first liquid guiding component is in the liquid inlet closed state, the liquid guiding channel 51 of the first liquid guiding component is closed, the aerosol generating matrix in the liquid guiding channel 51 will not leak, and the aerosol generating matrix cannot be supplied to the liquid guiding channel 51. When the first liquid guiding component is in the liquid inlet open state, the liquid guiding channel 51 of the first liquid guiding component is opened, and the aerosol generating matrix can be supplied to the liquid guiding channel 51 through the liquid replenishing device 6.

[0090] Regarding the structure of the removable element, in one embodiment, the removable element can be a sealing cap (not shown) covering the catheter 5. In one embodiment, in order to prevent the sealing cap from falling off, the sealing cap can be connected to the catheter 5 by any feasible means such as threaded connection, clamping, etc.

[0091] In one embodiment, the removable element may be a silicone plug (not shown in the figure), which is fixed to the catheter 5 in an interference fit manner.

[0092] In one embodiment, the insertion portion 52 is in the installation space 12. The removable element is used to seal the liquid inlet 511 on the insertion portion 52 before the liquid replenishing device 6 is installed in the atomizer.
