[0035] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0037] 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).

[0038] In the present application, the atomization device consists of a liquid storage tank and an atomization component arranged inside the liquid storage tank. A liquid storage component is usually provided inside the liquid storage tank to store the atomization matrix in liquid form. The atomization component is usually composed of an atomization outer tube, an atomization inner tube, a liquid guide component and a heating component. A suction nozzle and an air inlet are usually provided on the liquid storage tank. The atomization inner tube is passed through the interior of the atomization outer tube. The liquid guide component wraps the heating component and is arranged inside the atomization inner tube. A first liquid inlet hole is opened on the atomization outer tube, and a second liquid inlet hole is opened on the atomization inner tube. The first liquid inlet hole is connected to the second liquid inlet hole. The inner cavity of the atomizing inner tube forms an atomizing channel. Normally, the atomizing channel is arranged in a vertical direction, and the top end of the atomizing channel is connected to the suction nozzle, and the bottom end is connected to the air inlet. When the external temperature increases or the external air pressure decreases, the air inside the liquid storage tank (the air above the atomizing matrix stored in the liquid storage tank) expands, causing the air pressure inside the liquid storage tank to be greater than the external atmospheric pressure, causing a pressure difference between the inside and outside of the liquid storage tank, and then causing the atomized matrix to flow out through the first liquid inlet hole and the second liquid inlet hole under the action of gravity and flow to the air inlet, thereby leaking through the air inlet.

[0039] To solve this problem, some manufacturers reduce leakage by adding liquid absorbing parts, or develop special liquid storage materials, reduce the amount of liquid input, etc. However, the development of new materials is time-consuming and costly, and adding parts will also increase costs accordingly. Moreover, reducing leakage by reducing the amount of liquid input will affect the quality of the aerosol.

[0040] In view of the above problems, the present application proposes the following atomizer and atomizing device, so that the atomized matrix can flow back into the interior of the atomizing component after the pressure difference is restored.

[0041] See also Figure 1-Figure 10 As shown, the atomizer provided in this embodiment includes: a liquid storage component 10, an atomizing component 20 and a liquid passage 30, wherein the liquid storage component 10 can be used to store the atomizing matrix and provide the atomizing matrix to the atomizing component 20, and the atomizing component 20 can heat the atomizing matrix to form an aerosol by heating.

[0042] The liquid storage assembly 10 includes: a liquid storage tank 11 and a bottom cover 12. The interior of the liquid storage tank 11 has a liquid storage cavity 111 and an installation cavity 112, wherein the liquid storage cavity 111 is in a closed state relative to the installation cavity 112. The liquid storage cavity 111 is used to store the atomized matrix, and the bottom cover 12 is installed in the installation cavity 112.

[0043] The atomizer assembly 20 includes: an atomizer core 201 and an atomizer tube assembly 21. The atomizer tube assembly 21 is arranged at the periphery of the atomizer core 201. In other words, the atomizer core 201 is arranged inside the atomizer tube assembly 21. The atomizer tube assembly 21 is arranged in the liquid storage chamber 111. The atomizer tube assembly 21 is provided with a liquid inlet hole 211, which is connected to the liquid storage chamber 111. In a specific embodiment, the atomizer tube assembly 21 is penetrated into the liquid storage chamber 111, so that the liquid inlet hole 211 is connected to the liquid storage chamber 111, and the atomizer matrix in the liquid storage chamber 111 can enter the interior of the atomizer tube assembly 21 through the liquid inlet hole 211, and the atomizer core 201 can heat the atomizer matrix to generate aerosol.

[0044] In one embodiment of the present application, the atomizer core 201 includes a heating element 22 and a liquid guide element 221, wherein the liquid guide element 221 wraps the heating element 22, and the atomized matrix is ​​conducted to the liquid guide element 221 through the liquid inlet hole 211. The heating element 22 can generate heat energy under the action of electric energy to heat the atomized matrix.

[0045] One end of the liquid passage 30 is connected to the liquid inlet hole 211 , and the other end of the liquid passage 30 extends to the bottom cover 12 .

[0046] When the atomizer is in a pressure change (e.g., airplane transportation) or high temperature environment, the pressure inside the liquid storage chamber 111 increases relative to the external pressure, and a pressure difference is generated inside the liquid storage chamber 111 relative to the external environment. In the past, when the liquid passage 30 was not provided, the atomized matrix would flow into the inside of the atomizer or flow to the outside of the atomizer under the action of the pressure difference. In this embodiment, since one end of the liquid passage 30 is connected to the liquid inlet hole 211, the atomized matrix that has flowed out flows into the bottom cover 12 through the liquid passage 30.

[0047] In this embodiment, the inner diameter of the liquid passage 30 can provide capillary force, and then when the external atmospheric pressure is restored, the space above the atomizing matrix in the liquid storage chamber 111 increases in volume and relatively decreases in pressure due to the reduction of the atomizing matrix, so that the pressure in the liquid storage chamber 111 is less than the pressure difference caused by the decrease in the atmospheric pressure of the external environment. Then, the atomizing matrix that flows into the bottom cover 12 flows back to the atomizing tube assembly 21 and the liquid storage chamber 111 through the liquid passage 30 under the action of capillary force until the atmospheric pressure of the external environment and the internal pressure of the liquid storage chamber 111 reach a state of equilibrium. In this way, while avoiding the leakage of the atomizing matrix, it can also ensure that the atomizing matrix as a whole is not reduced, and does not affect the actual use of the user. Fig.11 As shown, the liquid storage assembly 10 provided in this embodiment further includes a buffer tank 121, a suction nozzle 113 is provided in the liquid storage tank 11, one end of the atomizing tube assembly 21 is connected to the suction nozzle 113, and the other end of the atomizing tube assembly 32 is connected to the air inlet 122. The atomized matrix flowing out through the liquid inlet 211 flows into the buffer tank 121 for buffering.

[0048] In one embodiment of the present application, the cache slot 121 is disposed on the bottom cover 12 , and an air inlet hole 122 penetrating the cache slot 121 is also disposed on the bottom cover 12 , and an inner slot wall of the cache slot 121 is provided with a non-wetting layer.

[0049] In actual application, the user can use the suction nozzle 113 to allow external gas to enter the interior of the atomizer tube assembly 21 through the air inlet hole 122 by suction, and the atomized matrix that enters the interior of the heating tube assembly 21 through the liquid inlet hole 211 generates aerosol under the action of heating by the atomizer core 201, and the aerosol is output through the suction nozzle 113 under the action of the airflow inside the atomizer tube assembly 21 for use by the user.

[0050] The atomized matrix buffered in the buffer tank 121 flows back to the inside of the atomizing tube assembly 21 through the liquid channel 30 until the atmospheric pressure of the external environment and the internal pressure of the liquid storage chamber 111 reach a balanced state. In this way, while avoiding the leakage of the atomized matrix, it can also ensure that the atomized matrix as a whole is not reduced, and does not affect the actual use of the user.

[0051] It should be noted that the inner wall of the buffer tank 121 is provided with a non-wetting layer, which has a smooth and dense outer surface. After the atomized matrix is ​​cached in the buffer tank 121, since the surface of the buffer tank 121 is provided with a non-wetting layer, the atomized matrix stored in the liquid storage cavity 111 is usually in liquid form, and the non-wetting layer can make the atomized matrix in liquid form form a ball state. Even if the height of the atomized matrix cached in the buffer tank 121 is higher than the height of the air inlet 122, since the atomized matrix is ​​in a ball state, it cannot leak from the air inlet 122.

[0052] In a preferred embodiment, the non-wetting layer is generally made of a non-wetting material such as a mixture of polypropylene (PP) and talcum powder.

[0053] In this embodiment, when the atomizer is in an environment of air pressure change or high temperature so that the internal pressure of the liquid storage chamber 11 increases relative to the external pressure, under the action of the pressure difference, the atomized matrix in the liquid storage chamber 11 flows out through the liquid inlet hole 211 and flows into the buffer groove 121 for buffering. When the external pressure is restored, the atomized matrix buffered in the buffer groove 121 flows back to the liquid storage chamber through the liquid channel 30 under the action of capillary force.

[0054] When the atomized matrix cached in the cache groove 121 refluxes, it is necessary to keep a portion of the atomized matrix remaining in the liquid passage 30, and keep the atomized matrix in the cache groove 121 and the atomized matrix remaining in the liquid passage 30 in a continuous state. Under the action of the pressure difference, the atomized matrix in the cache groove 121 can reflux through the liquid passage 30.

[0055] In this embodiment, see Figure 6 , Figure 7 and Fig.11 As shown, a guide body 123 is also provided on the cache groove 121, one end of the guide body 123 is connected to the other end of the liquid passage 30, and the other end of the guide body 123 extends to the bottom of the cache groove 121, and the guide body 123 is provided with a guide surface 1231 corresponding to the liquid passage 30, and the guide surface 1231 is used to guide the liquid-form atomized matrix in the liquid passage 30 to the bottom of the cache groove 121, thereby keeping the atomized matrix remaining in the liquid passage 30 and the atomized matrix in the cache groove 121 in a continuous state.

[0056] In one embodiment of the present application, a column 124 is provided on the cache slot 121 , and the guide body 123 is a guide slope arranged on the column 124 .

[0057] When the atomizer tube assembly 21 is inserted into the liquid storage cavity 111, in order to position the atomizer tube assembly 21, the atomizer assembly 20 provided in this embodiment further includes: a positioning frame 24, which is installed in the installation cavity 112 and is located between the bottom cover 12 and the liquid storage cavity 111. The positioning frame 24 is provided with a positioning groove 241, which penetrates the thickness direction of the positioning frame 24, and the atomizer tube assembly 21 is fixedly arranged in the positioning groove 241. The positioning frame 24 is also provided with an air hole 242 penetrating the positioning groove 241, and the air hole 242 is communicated with the air inlet hole 122, so that the other end of the atomizer tube assembly 21 is communicated with the air inlet hole 122 through the air hole 242.

[0058] In this embodiment, the liquid passage 30 includes a first liquid passage 23 and a second liquid passage 25. The first liquid passage 23 is arranged on the atomization tube assembly 21, and the second liquid passage 25 is arranged on the positioning frame 24. In a preferred embodiment, the second liquid passage 25 runs through the thickness direction of the positioning frame 24, and one end of the first liquid passage 23 is connected to the liquid inlet hole 211, and the other end of the first liquid passage 23 is connected to one end of the second liquid passage 25. The other end of the second liquid passage 25 extends to the bottom cover 12, that is, extends to the bottom of the cache slot 121.

[0059] As described above, the atomized matrix flowing out through the liquid inlet hole 211 due to the pressure difference flows into the interior of the buffer tank 121 through the first liquid passage 23, the second liquid passage 25 and the guide body 123. When the atomized matrix cached in the buffer tank 121 flows back, it flows back in the direction of the guide body 123, the second liquid passage 25 and the first liquid passage 23.

[0060] In one embodiment of the present application, the atomizer assembly 20 further includes a first seal 261 and a second seal 262 . The first seal 261 is disposed between the atomizer tube assembly 21 and the nozzle 113 , and the second seal 262 is disposed between the atomizer tube assembly 21 and the air hole 242 .

[0064] In this embodiment, the atomizing tube assembly 21 includes: an atomizing outer tube 212 and an atomizing inner tube 213, the atomizing inner tube 213 is arranged inside the atomizing outer tube 212, the heating element 22 is arranged inside the atomizing inner tube 213, and the first liquid passage 23 is arranged between the atomizing outer tube 212 and the atomizing inner tube 213. In other words, the first liquid passage 23 can be arranged on the inner wall of the atomizing outer tube 212 or on the outer wall of the atomizing inner tube 213. The atomizing outer tube 212 is provided with a first liquid inlet hole 214, and the atomizing inner tube 213 is provided with a second liquid inlet hole 215. The first liquid inlet hole 214 is connected with the second liquid inlet hole 215 to form a liquid inlet hole 211.

[0065] In a specific embodiment, when the atomizing inner tube 213 is inserted into the atomizing outer tube 212 , the first liquid inlet hole 214 overlaps with the second liquid inlet hole 215 , and the overlapped first liquid inlet hole 214 and second liquid inlet hole 215 form a liquid inlet hole 211 .

[0066] In this embodiment, the length of the atomizer outer tube 212 is greater than the length of the atomizer inner tube 213, so that the inner cavity of the atomizer outer tube 212 and the inner cavity of the atomizer inner tube 213 together form a channel for the flow of aerosol and external gas, one end of the channel is connected to the suction nozzle 113, and the other end is connected to the air inlet 122.

[0067] In one embodiment of the present application, the first liquid passage 23 is disposed on the tube wall of the atomizing inner tube 213 .

[0075] In summary, the atomizer and atomizing device provided by the present application, when the atomizer is in an air pressure change or high temperature environment, the internal pressure of the liquid storage chamber changes relative to the external pressure, that is, the internal pressure of the liquid storage chamber produces a pressure difference relative to the external environment, and the atomized matrix flows out from the liquid inlet hole through the liquid channel to the bottom cover. When the atmospheric pressure of the external environment is restored, the volume of the space above the atomized matrix in the liquid storage chamber increases due to the reduction of the atomized matrix, and the pressure is relatively reduced, so that the pressure in the liquid storage chamber is less than the atmospheric pressure of the external environment and there is a pressure difference, then the atomized matrix flowing into the bottom cover is reversed through the liquid channel under the action of capillary force to the inside of the atomizing tube assembly, until the atmospheric pressure of the external environment and the internal pressure of the liquid storage chamber reach a state of equilibrium. In this way, while avoiding leakage of the atomized matrix, it can also ensure that the atomized matrix as a whole is not reduced, and does not affect the actual use of the user.
