Description

Technical Field

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

[0002] Atomizing devices atomize a matrix into an aerosol using an atomizing component. The aerosol flows out from the nozzle of the atomizing device and is inhaled by the user. Some atomizing devices incorporate a temperature-sensitive sealing element. When the atomizing device heats up, the sealing element deforms and opens the liquid inlet, allowing the atomizing matrix to enter the atomizing component, thus preventing the atomizing component from being constantly immersed in the atomizing matrix. However, in existing atomizing devices, the timing of opening or closing the liquid inlet is often not sensitive to temperature. Utility Model Content

[0003] The main purpose of this application is to provide an atomizing device and an electronic cigarette to solve the technical problem that the timing of opening or closing the oil inlet in the atomizing device is often insensitive to temperature.

[0004] To achieve the above objectives, a first aspect of this application provides an atomizing device, the atomizing device comprising:

[0005] The housing has an oil storage chamber inside for storing atomizing matrix, and an atomizing pipe inside the oil storage chamber. A nozzle is formed on the upper part of the housing.

[0006] An atomizing component is disposed in the oil storage chamber and connected to the mist outlet pipe. The atomizing component includes a support member, an oil guide member, and a heating member arranged sequentially from the outside to the inside. The support member has a liquid inlet hole, through which the atomizing matrix enters the interior of the support member and contacts the oil guide member and the heating member.

[0007] A sealing element is disposed on the support element, and the sealing element can deform according to temperature to open or close the liquid inlet hole;

[0008] The heat insulation cover is fixed to the support member and covers the periphery of the enclosure member.

[0009] In some embodiments, the heat insulation cover includes a cylindrical structure and a top plate disposed on top of the cylindrical structure. The bottom end of the heat insulation cover has an opening, allowing the atomizing matrix to enter the interior of the heat insulation cover through the bottom opening. The top plate has a communicating hole and is sealed to the support member.

[0010] The connecting hole connects the atomizing component and the mist outlet pipe, or the support is inserted into the connecting hole, or the mist outlet pipe is inserted into the connecting hole.

[0011] In some embodiments, a first buffer net is provided within the bottom opening.

[0012] In some embodiments, the heat insulation cover has multiple flow ports on its periphery.

[0013] In some embodiments, the plurality of flow ports are offset from the closure.

[0014] In some embodiments, a second buffer mesh is provided within the flow port.

[0015] In some embodiments, the mesh density of the second buffer net gradually decreases from top to bottom.

[0016] In some embodiments, the peripheral wall of the heat insulation cover is a hollow wall.

[0017] In some embodiments, the thickness of the peripheral wall of the heat insulation cover is greater than 1 mm.

[0018] A second aspect of this application provides an electronic cigarette, comprising:

[0019] An electronic control device; and an atomizing device according to any one of the first aspects above, wherein the atomizing device is electrically connected to the electronic control device.

[0020] Compared with the prior art, this application provides an atomizing device. By setting a heat insulation cover, the intensity of liquid exchange of the atomizing matrix on the outside of the sealing component can be reduced, making the temperature of the corresponding area more stable. This makes the timing of opening and closing the liquid inlet in the atomizing device more sensitive to temperature, and can more accurately deform when the deformation temperature is reached on the inside. In addition, the relevant setting of the buffer mesh can further reduce the intensity of liquid exchange of the atomizing matrix on the outside of the sealing component, making the temperature of the corresponding area more stable. Therefore, the technical solution of this application achieves more precise and sensitive liquid inlet control of the atomizing component. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Nebulizers can be used in various fields, such as medical nebulization, beauty nebulization, and cigarette replacement. They primarily work by heating a nebulizing matrix to generate an aerosol, which can be a liquid matrix containing or without nicotine. A nebulizer typically includes a storage chamber for storing the nebulizing matrix and an atomizing component for heating and atomizing the matrix to generate an aerosol.

[0030] like Figures 1 to 3As shown, this application provides an atomizing device 100, which includes a housing 1, an atomizing component, and a sealing member 7. The housing 1 has an oil storage chamber 2 inside, which stores the atomizing matrix. An atomizing channel is formed inside the oil storage chamber 2, and a nozzle is formed on the upper part of the housing. The atomizing component is disposed within the oil storage chamber 2 and communicates with the atomizing channel, for introducing the atomizing matrix stored in the oil storage chamber 2 into its interior and heating and atomizing it to generate an aerosol. Specifically, the atomizing assembly includes a support member 3, an oil guide member 4, and a heating member 5, which are sequentially arranged from the outside to the inside. The support member 3 is fixedly connected to the housing 1 and supports the oil guide member 4 inside it. The oil guide member 4 can be a cylindrical oil guide cotton. The heating member 5 is provided inside the oil guide member 4. The heating member 5 can be a heating wire or a heating mesh, etc., without specific limitations. The support member 3 has a liquid inlet hole 6. The atomizing matrix stored in the oil storage chamber 2 enters the atomizing assembly through the liquid inlet hole 6, and then comes into contact with the oil guide member 4, and then into contact with the heating member 5. Finally, it is heated by the heating member 5 and atomized to generate an aerosol. A sealing member 7 is provided on the outer surface of the support member 3. Specifically, the sealing member 7 can cover the liquid inlet hole 6 on the support member 3. When the atomizing device is working or not working, the temperature inside the sealing member 7 changes. Correspondingly, the sealing member 7 can deform according to the temperature, thereby opening or closing the liquid inlet hole 6. In order to ensure that the sealing member 7 can deform accurately at the preset deformation temperature, the atomizing device 100 also includes a heat insulation cover 8, which is fixed to the support member 3 and covers the periphery of the sealing member 7.

[0031] Understandably, when the atomizing device is not in operation, the sealing member 7 can seal the liquid inlet 6, thereby isolating the interior of the atomizing component from the atomizing matrix stored in the oil storage chamber 2. This design prevents the internal components of the atomizing component (such as the oil guide 4) from being constantly immersed in the atomizing matrix, thus maintaining the oil absorption of the atomizing component and the taste of the atomized matrix. It also reduces the likelihood of atomizing matrix leakage during long-term storage or transportation. When the atomizing device is in operation, conditions can trigger the deformation of the sealing member 7. For example, when the atomizing device is in operation, the heating effect of the heating element 5 causes the inner side of the sealing member 7 to reach a certain temperature and deform. Specifically, the deformation of the sealing member 7 can bend and spring open in the direction away from its corresponding liquid inlet 6, thus automatically opening the liquid inlet 6 and releasing the isolation between the interior of the atomizing component and the atomizing matrix stored in the oil storage chamber 2. This allows sufficient atomizing matrix to enter the atomizing component and be atomized when the atomizing device is in operation.

[0032] In some embodiments, the sealing element 7 is made of at least two layers of materials with different coefficients of thermal expansion. This arrangement allows temperature to act as a trigger for deformation of the sealing element 7, thereby automatically opening the liquid inlet 6 when the atomizing device is in operation. For example, the sealing element 7 is made of two layers of materials with different coefficients of thermal expansion, where the inner layer has a higher coefficient of thermal expansion than the outer layer. When the inner layer of the sealing element 7 is heated by the heating element 5, its expansion is greater than that of the outer layer, causing the sealing element 7 to bend and spring open in a direction away from its corresponding liquid inlet 6. Specifically, the sealing element 7 can be a double-layered metal sheet.

[0033] Intuitively, the design of the insulation cover 8 allows the sealing element 7 to respond quickly and accurately to the deformation temperature. That is, deformation occurs directly once the inner temperature of the sealing element 7 reaches the preset deformation temperature, without deformation occurring before or after reaching the preset deformation temperature. Specifically, the sealing element 7 is made of at least two layers of materials with different coefficients of thermal expansion. The temperature difference between its inner and outer sides directly affects whether it can deform. When the atomizing equipment 100 is working or not working, the temperature inside the sealing element 7 rises or falls rapidly, reaching the deformation condition and causing deformation. Therefore, the design of the insulation cover 8 allows the atomizing matrix around the sealing element 7 to remain relatively stable, thus keeping the temperature on the outer side of the sealing element 7 relatively stable. This allows a large temperature difference to be quickly formed between the inner and outer sides when the temperature inside the sealing element 7 rises or falls rapidly, resulting in rapid and accurate deformation.

[0034] To maintain a relatively stable temperature on the outside of the sealing member 7, in the technical solution of this application, the heat insulation cover 8 may include a cylindrical structure and a top plate disposed on the top of the cylindrical structure. The bottom end of the heat insulation cover has a bottom opening, through which the atomizing matrix can enter the interior of the heat insulation cover. A connecting hole 81 is provided on the top plate, and the top plate is sealed to the support member 3. The connecting hole 81 connects the atomizing component and the mist outlet pipe, or the support member is inserted into the connecting hole 81, or the mist outlet pipe is inserted into the connecting hole 81. When the atomizing device 100 is working, the temperature of the atomizing matrix inside the insulation cover 8 is higher than that of the atomizing matrix outside the insulation cover 8 during the operation of the atomizing device 100. After the atomizing matrix inside the insulation cover 8 is consumed, the atomizing matrix with a lower temperature outside enters the insulation cover 8. The above arrangement allows the atomizing matrix with a lower temperature to enter the insulation cover 8 only from the bottom opening. Since the original atomizing matrix inside the insulation cover 8 has a higher temperature and a certain density difference with the atomizing matrix that enters the insulation cover 8 later, the atomizing matrix that enters from the bottom opening will reduce the degree of convection and mixing of the atomizing matrix inside the insulation cover 8 to a certain extent, thereby maintaining the relative stability of the temperature outside the sealing member 7.

[0035] In some embodiments, a first buffer net (not shown) is provided inside the bottom opening. The first buffer net can divert and refine the atomized matrix entering the heat insulation cover 8, and can also reduce the degree of convection and mixing of the atomized matrix inside the heat insulation cover 8 to a certain extent, thereby maintaining the relative stability of the temperature outside the sealing member 7.

[0036] To meet the liquid supply requirements, the circumferential surface of the insulation cover can be provided with multiple flow ports 82. Simultaneously, to prevent the atomized matrix entering through the flow ports 82 from directly impacting and disturbing the atomized matrix outside the sealing member 7, thus causing temperature changes, the multiple flow ports 82 are staggered with the sealing member. Furthermore, a second buffer mesh 83 can be provided within the flow ports. The mesh density of the second buffer mesh 83 gradually decreases from top to bottom to achieve different degrees of flow diversion and refinement from top to bottom. This ensures that a large liquid supply demand is met while also reducing the convection and mixing of the atomized matrix within the insulation cover 8 to a certain extent, thereby maintaining a relatively stable temperature outside the sealing member 7.

[0037] It is easy to understand that, in order to maintain a relatively stable temperature on the outside of the enclosure 7, the peripheral wall of the insulation cover can be set as a hollow wall, similar to the principle of hollow insulation bricks. This setting can improve the insulation effect of the insulation cover 8. In addition, the thickness of the peripheral wall of the insulation cover can be set to be greater than 1 mm, thereby further improving the insulation effect of the insulation cover 8.

[0038] In some embodiments, in order to enable the atomizing component to achieve more reasonable liquid inlet control, there are multiple liquid inlet holes 6, and the sealing member 7 is provided in a one-to-one correspondence with the liquid inlet hole 6; at least one sealing member 7 has a first deformation temperature, at least one sealing member 7 has a second deformation temperature, and the first deformation temperature is higher than the second deformation temperature.

[0039] Specifically, when the inner temperature of the seal 7 reaches its corresponding deformation temperature, the seal 7 will deform. Therefore, by setting a seal-related structural design with different deformation temperatures, this application can gradually open the liquid inlet according to actual needs, thereby achieving more reasonable liquid inlet control of the atomizing component. In actual use, the amount of atomizing matrix required by the user to replenish varies significantly depending on the usage scenario. For example, when a user is bored, they may only take one puff, while when a user has a high demand for inhalation, they may take large, continuous puffs. The amount of atomizing matrix required for these two scenarios differs significantly. To address this, the above-mentioned design allows the second deformation temperature to be reached when the user takes the first or first few puffs, thus quickly opening the liquid inlet 6 to replenish the atomizing matrix. As the user continues to inhale, the temperature continues to rise to reach the first deformation temperature, thereby opening more liquid inlets 6 to replenish sufficient atomizing matrix into the atomizing component.

[0040] Furthermore, for the atomizing device of this application, the sealing member 7 having the first deformation temperature can be configured corresponding to the liquid inlet 6 having the first aperture, and the sealing member 7 having the second deformation temperature can be configured corresponding to the liquid inlet 6 having the second aperture, wherein the first aperture is larger than the second aperture. It is easily understood that the above configuration allows the second deformation temperature to be reached when the user inhales for the first few puffs, thereby quickly opening the liquid inlet 6 to replenish an appropriate amount of atomizing matrix. When the user continues to inhale, the temperature continues to rise to reach the first deformation temperature, subsequently opening more liquid inlets 6 to quickly replenish sufficient atomizing matrix into the atomizing component, thereby achieving more reasonable liquid inlet control of the atomizing component.

[0041] This application also proposes an electronic cigarette, which includes an electronic control device and an atomizing device, wherein the atomizing device is electrically connected to the electronic control device. The specific structure of the atomizing device is as described in the above embodiments. Since this atomizing device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0042] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
