Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomizing device and atomizing equipment. Background Technology

[0002] The principle of atomizing devices is that the atomizing liquid is transferred from the oil tank to the atomizing chamber and seeps into the atomizing coil. The atomizing coil heats and atomizes the atomizing liquid for the user to inhale. However, existing atomizing devices may cause problems such as a burnt coil or poor atomization if the user inhales immediately after filling with oil. Therefore, it is usually necessary to wait for the atomizing liquid to fully wet the atomizing coil before inhaling, which requires users to wait a long time before using the device and reduces the user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide an atomizing device and atomizing equipment to address the issue of users having to wait a long time for the coil to be preheated before use.

[0004] An atomizing device, comprising:

[0005] The housing assembly has an internal oil storage chamber, an atomizing chamber, and an oil passing chamber. The oil storage chamber is used to store a liquid matrix. The atomizing chamber is provided with an atomizing core for atomizing the liquid matrix to generate an aerosol. The oil storage chamber and the atomizing chamber are interconnected through a first oil inlet. The oil storage chamber and the oil passing chamber are connected through an oil passing hole. The oil passing chamber and the atomizing chamber are connected through a second oil inlet.

[0006] A plugging member is disposed in the oil passage and is configured to expand from an initial state to the plugging state. When the plugging member is in the initial state, the oil passage and the second oil inlet are in communication with each other. When the plugging member is in the plugging state, the plugging member blocks at least one of the oil passage and the second oil inlet.

[0007] In one embodiment, the plugging element is configured to absorb the liquid matrix to expand from the initial state to the plugged state.

[0008] In one embodiment, the sealing element is expanded cotton.

[0009] In one embodiment, the flow area of ​​the first oil inlet is smaller than the flow area of ​​the oil passage and / or the second oil inlet.

[0010] In one embodiment, the atomizing device further includes a sealing element disposed within the oil passage chamber. During the expansion process, the sealing element drives the sealing element to move toward the oil passage hole and / or the second oil inlet hole. When the sealing element is in the blocked state, the sealing element is sealed between the inner wall of the oil passage chamber and the sealing element, and the sealing element covers the oil passage hole and / or the second oil inlet hole.

[0011] In one embodiment, when the plugging member is in the initial state, the plugging member has a plugging end face facing the oil passage, the sealing member is a sealing membrane disposed on the plugging end face, and the area of ​​the sealing membrane is smaller than the area of ​​the plugging end face.

[0012] In one embodiment, the housing assembly includes an outer shell, an inner shell, and a separator. The inner shell is disposed inside the outer shell and the atomizing chamber is disposed inside the inner shell. The circumferential surface of the inner shell is provided with the first oil inlet and the second oil inlet at intervals along the axial direction of the inner shell.

[0013] The separator is disposed between the outer shell and the inner shell, located between the second oil inlet and the first oil inlet. The separator has an oil storage chamber on the side of the inner shell facing the first oil inlet in the axial direction, and an atomizing chamber on the side facing the second oil inlet. The separator has an oil passage hole that passes through the inner shell in the axial direction.

[0014] In one embodiment, the oil passage includes a plurality of holes, which are circumferentially spaced around the inner shell.

[0015] And / or, the first oil inlet hole includes a plurality of first oil inlets, all of which are circumferentially spaced around the inner shell component;

[0016] And / or, the second oil inlet includes a plurality of first oil inlets, all of which are circumferentially spaced around the inner housing.

[0017] An atomizing device, comprising the atomizing apparatus as described in any of the preceding claims.

[0018] In one embodiment, the atomizing device further includes a cover member detachably disposed on the housing assembly. The housing assembly is also provided with an oil filling hole that is connected to the oil storage tank. When the cover member is installed on the housing assembly, the cover member closes the oil filling hole.

[0019] And / or, the cover is provided with a suction nozzle, and when the cover is installed on the housing assembly, the suction nozzle is connected to the atomizing chamber.

[0020] When using the aforementioned atomizing device for the first time, the coil needs to be lubricated to ensure that the liquid matrix fully wets the storage medium and the atomizing coil, thereby preventing dry burning. At this time, the sealing component can be controlled to its initial state, so that both the first and second oil inlets are directly or indirectly connected to the oil storage chamber and the atomizing chamber. Therefore, the liquid matrix in the oil storage chamber can enter the atomizing chamber through the first and second oil inlets, allowing the liquid matrix to quickly wet the storage medium and the atomizing coil. Users can then directly inhale without waiting, improving the user experience.

[0021] After the liquid storage medium and atomizer core are initially wetted, and the user uses the atomizer normally, to prevent leakage of atomized liquid into the atomizer chamber due to positive pressure caused by the secondary injection of liquid matrix and the oil reservoir, which could lead to the atomizer core becoming stagnant and affecting the flavor, the user can control the sealing component to expand to a blocking state after the first use of the atomizer. This blocks at least one of the oil inlet and the second oil inlet, cutting off the channel for the oil storage chamber to supply liquid matrix to the atomizer chamber via the oil inlet, leaving only the oil storage chamber connected to the atomizer chamber through the first oil inlet.

[0022] In this way, by expanding and sealing the oil inlet or the second oil inlet, only the first oil inlet is left to connect the oil storage tank and the atomizing tank. This reduces the flow rate of the liquid matrix in the oil storage tank into the atomizing tank, which can reduce the need for secondary injection of liquid matrix and prevent the atomizing liquid from leaking rapidly into the atomizing tank in scenarios such as high and low temperatures or positive pressure in the oil tank when the atomizing device is in a semi-oil state. This reduces the problem of the atomizing coil dying due to oil leakage from the atomizing tank, which affects the taste. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] In related technologies, existing atomizing devices may experience problems such as burnt coils or poor atomization if the user immediately inhales after filling with e-liquid. Therefore, it is usually necessary to wait for the e-liquid to fully saturate the atomizing coil before inhalation, which requires users to wait a long time before use and reduces the user experience.

[0038] However, if the inlet hole between the tank and the atomizer chamber 12 is enlarged to allow for rapid coil lubrication, the atomizer will leak atomized liquid into the chamber 12 during secondary refills, causing the coil 40 to become brittle and affecting the flavor. Furthermore, when the atomizer is in a half-filled state and experiences high or low temperatures, the positive pressure generated in the tank will also cause atomized liquid to rapidly enter the chamber 12 from the inlet hole, leading to leakage and further brittlement of the coil 40.

[0039] Based on the above issues, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the atomizing device according to an embodiment of this application is shown. The atomizing device provided in an embodiment of this application includes a housing assembly 10 and a sealing member 20. The housing assembly 10 has an oil storage chamber 11, an atomizing chamber 12 and an oil passage chamber 13 formed inside. The oil storage chamber 11 is used to store a liquid matrix. The atomizing chamber 12 is provided with an atomizing core 40 for atomizing the liquid matrix to generate an aerosol. The oil storage chamber 11 and the atomizing chamber 12 are interconnected through a first oil inlet 15. The oil storage chamber 11 and the oil passage chamber 13 are connected through an oil passage hole 14. The oil passage chamber 13 and the atomizing chamber 12 are connected through a second oil inlet 16.

[0040] It should be noted that, in this application, the housing assembly 10 refers to the structure used to form the oil storage tank 11, the atomizing tank 12, the oil passage tank 13, and to accommodate and support components such as the atomizing core 40. The shape of the housing assembly 10 may be, but is not limited to, cylindrical, flat elliptical, rectangular, etc.

[0041] The liquid matrix is ​​a flowable liquid aerosol generating matrix. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. Flavorings may contain ingredients that can provide users with various aromas or flavors. Vitamin mixtures may be mixtures containing at least one of vitamins A, B, C, and E, but are not limited to these.

[0042] For example, the liquid matrix is ​​a flowable e-liquid.

[0043] To facilitate the atomizing core 40 in atomizing the liquid matrix to generate an aerosol, a liquid storage medium 41 is also provided inside the atomizing chamber 12. The atomizing core 40 is located inside the liquid storage medium 41. The liquid storage medium 41 comprises a porous material containing numerous pores. The liquid matrix entering the atomizing chamber 12 can be absorbed by the liquid storage medium 41 and then heated by the internal atomizing core 40 to form an aerosol for the user to inhale. Optionally, the atomizing core 40 can be a heating coil, such as a resistance wire. The liquid storage medium 41 can be, but is not limited to, one or more of the following: sponge, paper fiber, cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, cellulose acetate, porous ceramic material, and polymer fiber.

[0044] The sealing element 20 is disposed in the oil passage 13 and is configured to expand from an initial state to a sealed state. When the sealing element 20 is in the initial state, the first oil inlet 15 and the second oil inlet 16 are interconnected. When the sealing element 20 is in the sealed state, it seals at least one of the oil passage 14 and the second oil inlet 16. It is understood that "the sealing element 20 sealing at least one of the oil passage 14 and the second oil inlet 16" means that, depending on the location of the sealing element 20, after expansion, the sealing element 20 can cover the entire oil passage 14, the entire second oil inlet 16, or both simultaneously.

[0045] Thus, when the sealing component 20 is in its initial state, the liquid matrix in the oil storage tank 11 can not only enter the atomizing chamber 12 through the first oil inlet 15, but also enter the oil passage 13 through the oil passage 14. The liquid matrix entering the oil passage 13 will then enter the atomizing chamber 12 through the second oil inlet 16, so that both the first oil inlet 15 and the second oil inlet 16 can discharge the liquid matrix. However, when the sealing component 20 is in the blocked state, regardless of whether the oil passage 14 or the second oil inlet 16 is blocked, the liquid matrix in the oil storage tank 11 cannot enter the atomizing chamber 12 through the oil passage 13. At this time, the oil storage tank 11 can only be connected to the atomizing chamber 12 through the first oil inlet 15.

[0046] When using the atomizing device for the first time, the coil needs to be lubricated to ensure that the liquid matrix fully wets the storage medium 41 and the atomizing coil 40, thereby preventing dry burning of the storage medium 41 and the atomizing coil 40. At this time, the sealing component 20 can be controlled to be in its initial state, so that the first oil inlet 15 and the second oil inlet 16 are directly or indirectly connected to the oil storage chamber 11 and the atomizing chamber 12. Therefore, the liquid matrix in the oil storage chamber 11 can enter the atomizing chamber 12 through the first oil inlet 15 and the second oil inlet 16, thereby allowing the liquid matrix to quickly wet the storage medium 41 and the atomizing coil 40. Users can directly inhale without waiting time, improving the user experience.

[0047] After the liquid storage medium 41 and the atomizing core 40 are initially wetted, and the user uses the atomizing device normally, to prevent leakage of atomizing liquid into the atomizing chamber 12 due to positive pressure caused by the secondary injection of liquid matrix and the oil storage tank 11, which could lead to the atomizing core 40 becoming waterlogged and affecting the taste, the user can control the sealing component 20 to expand to a sealed state after the first use of the atomizing device. This seals at least one of the oil inlet 14 and the second oil inlet 16, cutting off the channel for the oil storage tank 11 to deliver the liquid matrix to the atomizing chamber 12 via the oil inlet 13, leaving only the oil storage tank 11 connected to the atomizing chamber 12 through the first oil inlet 15.

[0048] In this way, by expanding and sealing the oil inlet 14 or the second oil inlet 16 through the sealing component 20, only the first oil inlet 15 is left to connect the oil storage chamber 11 and the atomizing chamber 12. This reduces the flow rate of the liquid matrix in the oil storage chamber 11 into the atomizing chamber 12, which can reduce the secondary injection of liquid matrix and the rapid leakage of atomizing liquid into the atomizing chamber 12 in scenarios such as high and low temperature scenarios when the atomizing device is in a half-oil state and positive pressure is generated in the oil tank. This reduces the problem of the atomizing core 40 being soaked and dying due to oil leakage from the atomizing chamber 12, thus affecting the taste.

[0049] In some embodiments of this application, see [reference] Figure 1 and Figure 2The sealing element 20 is configured to absorb the liquid matrix and expand, and during the expansion process, the sealing element 20 switches from the initial state to the sealing state. In actual use, when the atomizing device is in its factory condition and has not been used by the user, the sealing element 20 is in an unexpanded state, that is, the sealing element 20 is in the initial state, and the oil passage 14 and the second oil inlet 16 are in a state of mutual communication.

[0050] When a user first injects liquid matrix into the reservoir 11 and aspirates, the liquid matrix enters the atomizing chamber 12 through the oil passage 14. A portion of the liquid matrix entering the atomizing chamber 12 continues to flow into the atomizing chamber 12 along the second oil inlet 16, thus working with the first oil inlet 15 to achieve rapid coil lubrication. The remaining liquid matrix entering the atomizing chamber 12 is absorbed by the sealing component 20, causing the sealing component 20 to expand. As lubrication is completed, the sealing component 20 also seals at least one of the oil passage 14 and the second oil inlet 16.

[0051] In this way, when the atomizer is lubricated, the lubrication speed can be increased through the oil passage 14, the oil chamber 13, and the second oil inlet 16. After lubrication is completed, the sealing component 20 will automatically expand to block at least one of the oil passage 14 and the second oil inlet 16. This ensures that during subsequent secondary injections of liquid matrix, and when the user uses the atomizer, the liquid matrix only flows into the atomizing chamber 12 from the first oil inlet 15. The speed and flow rate are less than the amount of liquid matrix injected during the first injection. This ensures that there will be no leakage from the second oil inlet 16 during secondary and multiple injections of liquid matrix, and also ensures that there will be no leakage during user use. This reduces the problem of the atomizer coil 40 becoming stagnant and affecting the taste.

[0052] Optionally, the sealing component 20 is an expanding cotton 21. The expanding cotton 21 is made of 100g flax cotton stacked and compressed in multiple layers. The thickness of each layer of flax cotton is about 0.55mm, and the thickness after compression is about 0.2mm, which is close to 3 times the original thickness. In some specific embodiments, the expanding cotton 21 is made of 12 layers of 100g flax cotton stacked together and compressed from a thickness of 6.6mm to a thickness of 2.0mm. When the expanding cotton 21 absorbs the liquid matrix and expands, it will expand at least 3 times, and the thickness will return to more than 6mm, thereby achieving the sealing of the oil passage 14 and the second oil inlet 16.

[0053] In actual use, the expansion cotton 21 is positioned below the oil passage hole 14, and its maximum thickness is greater than the height of the entire oil passage chamber 13. This allows the expansion cotton 21 to absorb the liquid matrix and expand upwards, first abutting against the inner wall of the oil passage chamber 13, and then expanding towards the interior of the oil passage hole 14, thus sealing the oil passage hole 14. It is understood that in other embodiments, the maximum expansion volume of the expansion cotton 21 can be greater than the volume of the entire oil passage chamber 13, allowing it to expand to fill the entire chamber after absorbing the liquid matrix, thereby simultaneously sealing the oil passage hole 14 and the second oil inlet hole 16.

[0054] It should be noted that in some other embodiments, the sealing element 20 may also be made of an oil-absorbing and expandable rubber material. In some embodiments, the sealing element 20 may also be an inflatable airbag, which, when used with an air pump, allows the user to manually or automatically inflate the airbag after the initial oil injection, thereby expanding the airbag and sealing the oil inlet 14 or the second oil inlet 16.

[0055] In some embodiments, since the absorbent cotton is also a porous material after expansion, even if it blocks the oil inlet 14 or the second oil inlet 16 after expansion, the liquid matrix in the oil storage tank 11 will still seep into the absorbent cotton through the second oil inlet 16 and flow into the atomizing chamber 12. Thus, the liquid matrix in the oil storage tank 11 will continuously seep into the atomizing chamber 12. If the atomizing device is not used for a long time, a large amount of liquid matrix will seep into the atomizing chamber 12, causing the atomizing coil 40 in the atomizing chamber 12 to become saturated and die. When the user uses the atomizing device again, it will affect the user's vaping experience.

[0056] Therefore, the atomizing device also includes a sealing element 22, which is disposed within the oil passage chamber 13. When the blocking element 20 is in its initial state, the sealing element 22 is located between the oil passage hole 14 and the blocking element 20. As the blocking element 20 absorbs the liquid matrix and expands, it will cause the sealing element 22 to move towards the oil passage hole 14. Furthermore, when the blocking element 20 expands to its maximum, i.e., when the blocking element 20 is in a blocking state, the sealing element 22 is sealed between the inner wall of the oil passage chamber 13 and the blocking element 20, and the sealing element 22 covers the oil passage hole 14.

[0057] In this way, the sealing element 22 can achieve a secondary seal on the oil passage 14. Together with the plugging element 20, the oil passage 14 can be completely blocked, thereby preventing the liquid matrix of the oil storage tank 11 from penetrating into the plugging element 20, thus reducing the liquid matrix penetrating into the atomizing chamber 12, reducing the phenomenon of the atomizing core 40 being soaked and dead, and ensuring the taste of the user when using the atomizing device.

[0058] Furthermore, the flow area of ​​the first oil inlet 15 is smaller than that of the oil passage 14 and the second oil inlet 16, so that the first oil inlet 15 is a through hole with a smaller diameter, while the oil passage 14 and the second oil inlet 16 are circular holes or strip-shaped holes with larger diameters. When the second oil inlet 16 is a strip-shaped hole, the extension direction of the second oil inlet 16 is parallel to the circumferential direction of the inner shell 31. In this way, on the one hand, the liquid matrix can be quickly introduced from the oil storage tank 11 into the atomizing chamber 12 through the larger diameter oil passage 14 and the second oil inlet 16, thereby achieving rapid wicking; on the other hand, by controlling the first oil inlet 15 to be a smaller through hole, a thin film can be formed on the surface of the first oil inlet 15 to prevent the liquid matrix from penetrating into the atomizing chamber 12 from the first oil inlet 15.

[0059] Specifically, in actual use, the oil passage 14 and oil chamber 13 are located below the oil storage chamber 11, and the first oil inlet 15 is also located near the bottom of the oil storage chamber 11. After the oil storage chamber 11 is filled with oil for the first time, when the user draws air into the atomizing chamber 12 to create negative pressure, under the action of negative pressure, some of the liquid matrix will flow into the oil chamber 13 through the oil passage 14, so as to realize the oil output of the second oil inlet 16 and the absorption and expansion of the sealing component 20. The other part of the liquid matrix will enter the atomizing chamber 12 through the first oil inlet 15, and work with the second oil inlet 16 to achieve rapid coil lubrication.

[0060] After the user finishes using the atomizer for the first time, either the oil inlet 14 or the second oil inlet 16 is blocked by the sealing component 20. Although the liquid matrix still tends to move towards the atomizing chamber 12 through the first oil inlet 15 under the influence of gravity, since the user no longer inhales, a continuous surface film of liquid matrix forms on the surface of the first oil inlet 15. The contractile or binding force of the film counteracts the gravity of the liquid, thus preventing the liquid matrix from passing through the first oil inlet 15. Therefore, when the user is not using the atomizer, the liquid matrix will not permeate into the atomizing chamber 12 from the first oil inlet 15. The second oil inlet 16 is also blocked by the sealing component 20, thereby reducing the problem of the atomizer coil 40 becoming stagnant due to prolonged disuse of the atomizer. When the user uses the atomizing device again, the flow of the liquid matrix can disrupt the surface film of the first oil inlet 15, thereby weakening the film's contraction or binding force, so that the liquid matrix can pass through the first oil inlet 15 normally and enter the atomizing chamber 12, where it is atomized by the atomizing core 40 to form an aerosol for the user to inhale.

[0061] Meanwhile, when the user injects liquid matrix a second time, or when the atomizer is in a half-oil state and experiences high or low temperatures, or when positive pressure is generated in the oil tank, the tendency of the liquid matrix to move towards the atomizing chamber 12 will be enhanced. However, after the first oil injection, the sealing component 20 will block the connection between the second oil inlet 16 and the oil storage chamber 11, leaving only the first oil inlet 15 connecting the oil storage chamber 11 and the atomizing chamber 12. Even if the liquid matrix breaks through the surface film of the first oil inlet 15, it can only enter the atomizing chamber 12 through the smaller diameter first oil inlet 15, thereby reducing and slowing down the leakage of liquid matrix into the atomizing chamber 12, and thus reducing the problem of the atomizing core 40 becoming stagnant and affecting the taste.

[0062] In some embodiments, when the sealing member 20 is in its initial state, the sealing member 20 has a sealing end face 23 facing the oil passage 14, and the sealing member 22 is a sealing film disposed on the sealing end face 23, and the area of ​​the sealing film is smaller than the area of ​​the sealing end face 23, and part of the sealing film is located on the projection of the oil passage 14 onto the sealing end face 23. In actual use, the sealing member 20 is located below the oil passage 14, so the top surface of the sealing member 20 is the sealing end face 23. The liquid matrix flowing from the oil passage 14 into the oil tank 13 will contact the sealing end face 23 of the sealing member 20. Since the area of ​​the sealing film is smaller than the area of ​​the sealing end face 23, the sealing film will not completely cover the sealing end face 23 of the sealing member 20. Therefore, the liquid matrix can directly contact the sealing member 20 and be absorbed by the sealing member 20, causing the sealing member 20 to expand. After expanding, the sealing element 20 will move together with the sealing membrane toward the oil passage 14 until the sealing element 20 and the sealing membrane seal the oil passage 14.

[0063] In other embodiments, the sealing element 22 can also be disposed on the sealing end face 23 of the plugging element 20 facing the second oil outlet. When the plugging element 20 absorbs the liquid matrix and expands, the expansion of the plugging element 20 will push the sealing element 22 toward the second oil inlet 16 until the sealing element 22 is sealed between the inner wall of the oil tank and the plugging element 20, and the sealing element 22 covers the second oil inlet 16, so as to seal the second oil inlet 16 through the sealing element 22 and the plugging element 20. It can be understood that when the sealing element 22 is disposed on the sealing end face 23 of the second oil outlet side of the plugging element 20, the area of ​​the sealing element 22 can be the same as or larger than the area of ​​the sealing end face 23. That is, the size of the sealing element 22 is not limited, as long as the sealing element 22 does not cover the entire plugging element 20 and the liquid matrix flowing in from the oil outlet 14 can be absorbed by the plugging element 20.

[0064] Optionally, the sealing membrane is a plastic film to make it lightweight, facilitating its movement as the sealing member 20 expands. Furthermore, to prevent the sealing membrane from detaching, it can be adhesively fixed to the surface of the sealing member 20. It is understood that in other embodiments, the sealing member can also be a component with elastic sealing properties, such as a rubber part.

[0065] In some embodiments of this application, the housing assembly 10 includes an outer shell 30, an inner shell 31, and a separator 32. Both the inner shell 31 and the outer shell 30 are cylindrical, and the inner shell 31 is disposed inside the outer shell 30. An atomizing chamber 12 is disposed inside the inner shell 31. A first oil inlet hole 15 and a second oil inlet hole 16 are provided at intervals along the axial direction of the inner shell 31 on the circumferential surface of the inner shell 31. The separator 32 is disposed between the outer shell 30 and the inner shell 31, located between the second oil inlet hole 16 and the first oil inlet hole 15. An oil storage chamber 11 is formed on the side of the inner shell 31 facing the first oil inlet hole 15 along the axial direction, and an atomizing chamber 12 is formed on the side facing the second oil inlet hole 16. An oil passage hole 14 is provided on the separator 32, penetrating along the axial direction of the inner shell 31.

[0066] The housing assembly 10 also includes a support member 33, which is located on the side of the separator 32 facing the second oil inlet 16 and is arranged circumferentially around the inner housing 31. The support member 33, outer housing 30, inner housing 31, and separator 32 together form the oil passage 13. In the initial state, the sealing member 20 is an annular structure arranged on the support member 33 and circumferentially around the inner housing 31. The top of the sealing member 20 is provided with a sealing end face 23, and a sealing element 22 is provided on the sealing end face 23. When liquid matrix flows into the oil passage 14 into the oil passage 13, the sealing member 20 absorbs the liquid matrix and expands upward, thereby sealing the oil passage 14.

[0067] Furthermore, in order to achieve uniform oil intake from the oil storage chamber 11 to the atomizing chamber 12 and avoid uneven wetting of the liquid matrix in the liquid storage medium 41, which would affect the taste, multiple first oil inlets 15 are provided. All the first oil inlets 15 are arranged circumferentially around the inner shell 31, so that all the first oil inlets 15 are arranged circumferentially around the separator 32 on the circumferential surface of the inner shell 31. This allows the oil storage chamber 11 surrounding the atomizing chamber 12 to achieve uniform oil intake through multiple first oil inlets 15, ensuring the wetting effect of the liquid matrix.

[0068] Furthermore, the oil passage 14 includes multiple holes, all of which are circumferentially spaced around the inner shell 31. Similarly, the second oil inlet 16 also includes multiple holes, all of which are spaced around the inner shell 31. This allows for uniform oil intake from the oil storage chamber 11 to the oil passage chamber 13 through the multiple oil passages 14, ensuring a uniform distribution of the liquid matrix within the oil passage chamber 13. The spaced second oil inlets 16 on the surface of the inner shell 31 also ensure that the liquid matrix within the oil passage chamber 13 can uniformly enter the atomizing chamber 12. Thus, the multiple oil passages 14 and multiple second oil inlets 16 not only further accelerate the lubrication process but also guarantee the uniformity of lubrication through the evenly distributed second oil inlets 16.

[0069] This application also provides an atomizing device, including the atomizing apparatus as described in any of the above embodiments. The atomizing device further includes a battery assembly and an airflow sensor, etc. The battery assembly is electrically connected to the atomizing core 40 and is used to supply power to the atomizing core 40. The airflow sensor is used to sense changes in airflow within the atomizing housing during inhalation, in order to control the output power of the battery assembly 103. The airflow sensor can be a microphone sensor or a MEMS sensor, etc.

[0070] The atomizing device also includes a cover 42, which is detachably mounted on the housing assembly 10. The housing assembly 10 is also provided with an oil filling hole 44, which is connected to the oil storage chamber 11. When the cover 42 is installed on the housing assembly 10, the cover 42 closes the oil filling hole 44. When the cover 42 is separated from the housing assembly 10, the oil filling hole 44 opens, connecting with the external space of the oil storage chamber 11. At this time, the user can inject liquid matrix into the oil storage chamber 11 through the oil filling hole 44. Furthermore, the cover 42 is provided with a mouthpiece 43. When the cover 42 is installed on the housing assembly 10, the mouthpiece 43 is connected to the atomizing chamber 12, so that the aerosol formed in the atomizing chamber 12 can be inhaled by the user through the mouthpiece 43.

[0071] The above-mentioned atomizing device has at least the following advantages:

[0072] When using the atomizing device for the first time, the coil needs to be lubricated to ensure that the liquid matrix fully wets the storage medium 41 and the atomizing coil 40, thereby preventing dry burning of the storage medium 41 and the atomizing coil 40. At this time, the sealing component 20 can be controlled to be in its initial state, so that the first oil inlet 15 and the second oil inlet 16 are directly or indirectly connected to the oil storage chamber 11 and the atomizing chamber 12. Therefore, the liquid matrix in the oil storage chamber 11 can enter the atomizing chamber 12 through the first oil inlet 15 and the second oil inlet 16, thereby allowing the liquid matrix to quickly wet the storage medium 41 and the atomizing coil 40. Users can directly inhale without waiting time, improving the user experience.

[0073] After the liquid storage medium 41 and the atomizing core 40 are initially wetted, and the user uses the atomizing device normally, to prevent leakage of atomizing liquid into the atomizing chamber 12 due to positive pressure caused by the secondary injection of liquid matrix and the oil storage tank 11, which could lead to the atomizing core 40 becoming waterlogged and affecting the taste, the user can control the sealing component 20 to expand to a sealed state after the first use of the atomizing device. This seals at least one of the oil inlet 14 and the second oil inlet 16, cutting off the channel for the oil storage tank 11 to deliver the liquid matrix to the atomizing chamber 12 via the oil inlet 13, leaving only the oil storage tank 11 connected to the atomizing chamber 12 through the first oil inlet 15.

[0074] In this way, by expanding and sealing the oil inlet 14 or the second oil inlet 16 through the sealing component 20, only the first oil inlet 15 is left to connect the oil storage chamber 11 and the atomizing chamber 12. This reduces the flow rate of the liquid matrix in the oil storage chamber 11 into the atomizing chamber 12, which can reduce the secondary injection of liquid matrix and the rapid leakage of atomizing liquid into the atomizing chamber 12 in scenarios such as high and low temperature scenarios when the atomizing device is in a half-oil state and positive pressure is generated in the oil tank. This reduces the problem of the atomizing core 40 being soaked and dying due to oil leakage from the atomizing chamber 12, thus affecting the taste.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
