Atomizing hood, atomizing hood assembly, atomizing device and atomizing equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application filed on December 5, 2023, application number: 2023116529230, entitled: Atomizing hood, atomizing hood assembly, atomizing device and atomizing equipment, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of aerosol generating devices, and in particular to an atomizing hood, an atomizing hood assembly, an atomizing device and an atomizing equipment. Background Art

[0004] An electronic atomizer is a microelectronic atomizer device that generates aerosols to replace cigarettes. Common electronic atomizers on the market include a power supply assembly and an atomizer assembly connected to the power supply assembly. The atomizer assembly is the core component of the electronic atomizer device and is mainly used to heat, atomize, and discharge the atomized liquid stored in the electronic atomizer device under the action of the electrical energy provided by the power supply assembly. The atomizer assembly includes a liquid storage tank, an atomizer core, a vent tube, and other structures. The atomizer core and the vent tube are arranged in the liquid storage tank. The bottom of the atomizer core is provided with an air inlet and the top is provided with an air outlet, which is connected to the vent tube. A liquid hole is provided between the liquid storage tank and the atomizer core. The atomized liquid in the liquid storage tank enters the atomizer core through the liquid hole, is heated and atomized by the heating element in the atomizer core, and is discharged from the vent tube.

[0005] Electronic atomization devices in related technologies usually do not have a pressure relief structure, which can cause problems for users when using the electronic atomization device. On the one hand, after the liquid storage tank is filled with atomizing liquid, the air from the external environment will be pressed into the liquid storage tank when the atomizing component is assembled, making the atmospheric pressure inside the liquid storage tank greater than the external atmospheric pressure. In order to achieve air pressure balance, the atmospheric pressure inside the liquid storage tank will press the atomizing liquid outward, causing the atomizing liquid to leak out, which affects both the user experience and the service life of the product. Therefore, a sealing structure is required to seal the liquid storage tank to prevent the atomizing liquid from leaking. On the other hand, when the amount of atomized liquid in a sealed liquid storage tank decreases to a certain level, the negative pressure inside the liquid storage tank makes it difficult for the atomized liquid in the liquid storage tank to enter the atomizer core through the liquid hole. This reduces the amount of atomized liquid entering the atomizer core, significantly reducing the amount of aerosol smoke, causing abnormal atomization of the atomized liquid and dry burning. This can directly cause the heating element to burn and produce odor, and even cause accidents, thus affecting the vaping experience of the electronic atomizer device. Therefore, making the atomizer component both sealed and breathable is a conflicting requirement and difficult to achieve in general designs. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0045] In the description of this application, if there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0046] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0047] In the description of this application, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0048] 1 to 6 , an embodiment of the present application provides an atomizing hood 320, which is applied to an atomizing device 10. The atomizing device 10 includes a liquid storage chamber and an atomizing core. The atomizing hood 320 includes: a hood body, which is configured to provide space for the atomizing core; at least one liquid inlet 321, which is provided on a side wall of the hood body, and the liquid inlet 321 is used to connect the liquid storage chamber and the atomizing core; and at least one auxiliary air passage structure 322, which is provided on an outer wall of the hood body, and one end of the auxiliary air passage structure 322 is used to connect the liquid storage chamber, and the other end of the auxiliary air passage structure 322 is used to connect the external environment.

[0049] After the aerosol matrix is ​​injected into the liquid storage chamber, only a small amount of air remains in the liquid storage chamber, or the liquid storage chamber is nearly airless. As the aerosol matrix is ​​gradually consumed during use, when the amount of aerosol matrix in the liquid storage chamber decreases to a certain level, the air pressure in the liquid storage chamber becomes significantly lower than the external atmospheric pressure, resulting in a negative pressure between the liquid storage chamber and the external atmospheric pressure. This makes it difficult for the aerosol matrix in the liquid storage chamber to normally enter the atomizer core through the liquid inlet 321.

[0050] In this embodiment, an auxiliary air passage structure 322 is provided on the side wall of the atomizing hood 320. During the user's inhalation process, the auxiliary air passage structure 322 can connect the liquid storage chamber with the external environment, thereby balancing the external air pressure and the air pressure in the liquid storage chamber, so that the aerosol matrix can smoothly pass through the liquid inlet 321 and penetrate into the atomizing core provided in the internal channel of the atomizing hood 320.

[0051] The auxiliary air flow structure 322 is used to provide an auxiliary air flow channel during the suction process, and the external ambient air flows into the liquid storage cavity through the auxiliary air flow channel, thereby preventing the air pressure in the liquid storage cavity from being significantly lower than the external ambient air pressure.

[0052] In some embodiments, the auxiliary air flow structure 322 is a channel arranged on the outer wall of the housing, and the auxiliary air flow structure 322 has a capillary adsorption effect.

[0053] Through the arrangement of this embodiment, when the aerosol matrix in the liquid storage chamber can normally enter the interior of the atomizer core through the liquid inlet 321, the auxiliary air permeation structure 322 adsorbs the aerosol matrix flowing into the auxiliary air permeation structure 322 through capillary action to prevent the aerosol matrix from falling; when the liquid storage chamber is under negative pressure, when the aerosol matrix in the liquid storage chamber is difficult to normally enter the interior of the atomizer core through the liquid inlet 321, the aerosol matrix adsorbed on the auxiliary air permeation structure 322 flows back into the liquid storage chamber. At this time, the auxiliary air permeation structure 322 can connect the external environment and the liquid storage chamber, thereby balancing the external air pressure and the air pressure in the liquid storage chamber, so that the aerosol matrix can naturally flow into the atomizer core.

[0054] In some embodiments, the auxiliary air flow structure 322 is disposed through the peripheral wall of the cover.

[0055] The hollow atomizing cover 320 serves as part of the atomizing channel, and the auxiliary air flow structure 322 passes through the peripheral wall of the cover. The auxiliary air flow structure 322 can communicate with the external environment through the atomizing channel inside the atomizing cover 320 to achieve air pressure balance inside and outside the liquid storage cavity.

[0056] For example, during the user's inhalation process, part of the airflow in the main atomization channel enters the auxiliary air passage structure 322, and passes through the auxiliary air passage structure 322 through the side wall of the atomization cover 320 into the liquid storage chamber, thereby ensuring that the air pressure in the liquid storage chamber is always balanced with the outside.

[0057] In some embodiments, the auxiliary air passage structure 322 is a recessed structure provided on the peripheral wall of the cover body, wherein the recessed structure is formed on the peripheral wall of the cover body on the side facing the liquid storage chamber.

[0058] Compared with the auxiliary air-passing structure 322 provided through the atomizing hood 320, this embodiment forms an axially extending depression on the hood body, and uses the axially extending depression as the auxiliary air-passing structure 322 to avoid excessive connectivity between the liquid storage chamber and the external environment, so that external gas can continue to enter the liquid storage chamber and cause the risk of oil leakage.

[0059] Only when the user inhales, a large amount of airflow flows into the atomizer hood 320 in a short period of time, and forces part of the airflow to enter the oil storage chamber along the auxiliary air flow structure 322, thereby dynamically maintaining the internal and external air pressure balance during inhalation, while avoiding the risk of aerosol matrix leaking from the auxiliary air flow structure 322 when stationary.

[0060] In some embodiments, the auxiliary gas flow structure 322 is at least one of a wave shape, a spiral shape, and a zigzag shape.

[0061] When the width and height are constant, by increasing the length of the auxiliary air passage structure 322, the volume within the auxiliary air passage structure 322 is increased, thereby allowing the auxiliary air passage structure 322 to accommodate more aerosol substrate. Therefore, this embodiment is not limited to the above-mentioned shape; any solution that can increase the volume more than a straight line falls within the scope of protection of this embodiment.

[0062] In some embodiments, the liquid inlet 321 passes through the peripheral wall of the cover body, and at least one liquid inlet 321 is arranged in multiple layers around the atomizer core.

[0063] This embodiment increases the contact area between the atomizing core and the liquid storage chamber by setting, so that the aerosol matrix can quickly lubricate the core. Compared with increasing the diameter of the liquid inlet 321, this embodiment reduces the risk of oil leakage.

[0064] In some embodiments, the atomizing cover 320 further includes an auxiliary air hole 323 disposed on the side wall of the cover body, wherein one end of the auxiliary air passage structure 322 is connected to the liquid inlet 321 , and the other end is connected to the auxiliary air hole 323 .

[0065] This embodiment connects the auxiliary air flow structure 322 to the liquid inlet 321. In the non-inhalation state, or when the oil reservoir chamber is at pressure equilibrium with the external environment, excess aerosol matrix in the liquid inlet 321 is stored through capillary action. When the user inhales, the liquid reservoir chamber is placed under a slight negative pressure. Airflow enters the auxiliary air flow structure 322 through the auxiliary air holes 323, pushing the aerosol matrix within the auxiliary air flow structure 322 back into the liquid reservoir chamber. This increases the instantaneous hydraulic pressure of the oil reservoir chamber, allowing the aerosol matrix to quickly penetrate the liquid-guiding cotton within the atomizing hood 320. Furthermore, some airflow enters the liquid reservoir chamber, thereby balancing the pressure within the liquid reservoir chamber with that of the external environment.

[0066] An embodiment of the present application further provides an atomizing hood assembly, comprising: the atomizing hood 320 of any of the above embodiments; a packaging base 200, the packaging base 200 being used to seal the liquid storage cavity; wherein the atomizing hood 320 and the packaging base 200 are integrally arranged.

[0067] By replacing the conventional metal atomizing hood 320 with an atomizing hood 320 formed by injection molding of a high-temperature resistant polymer material, production costs can be reduced. By making a corresponding mold, an atomizing hood assembly including the atomizing hood 320 structure and the packaging base 200 structure is formed by integral injection molding, so as to optimize the processing technology while ensuring that the relative positions of the atomizing hood 320 and the packaging base 200 are fixed. The arrangement of this embodiment makes the overall structure of the atomizing device more compact, improving the user experience; it saves the manual assembly costs and working hours of multiple components in product production, facilitating automated production; at the same time, by eliminating high-cost components, the company's production costs are reduced.

[0068] As shown in Figure 6, the package base 200 is provided with an air inlet 210, which allows airflow between the external environment and the internal cavity enclosed by the package base 200. By manufacturing the atomizer cover assembly through a one-piece injection molding method, it is ensured that the air passage within the atomizer assembly will not be deformed after assembly due to tolerances between the components, resulting in increased draw resistance.

[0069] 9 to 12 , an embodiment of the present application further provides an atomizing device 10, which includes: a shell 100, wherein one end of the shell 100 is open and the other end extends inwardly to provide an atomizing pipe 370; an atomizing cover 320 such as any of the above embodiments, wherein the atomizing cover 320 is connected to the atomizing pipe 370; a sealing member 360, which is connected to the shell 100 and the atomizing cover 320 so that the sealing member 360, the shell 100, and the atomizing cover 320 form a liquid storage chamber; an atomizing core, which is arranged in the atomizing cover 320 and is configured to atomize an aerosol matrix of the liquid storage chamber; wherein the liquid inlet 321 of the atomizing cover 320 is used to connect the liquid storage chamber and the atomizing core; an auxiliary air passage structure 322 is connected to the sealing member 360 to form an auxiliary airway, wherein one end of the auxiliary air passage structure 322 is used to connect the liquid storage chamber, and the other end of the auxiliary air passage structure 322 is used to connect the external environment.

[0070] The atomizer 10 has entered an activated state, as shown in FIG11 . When a user uses the atomizer 10 for inhalation, airflow from the environment flows into the internal cavity through the air inlet 210 on the bottom wall of the package base 200. The internal airflow is primarily divided into three directions: the first direction is from the bottom of the package cover into the main atomization duct, where the aerosol matrix is ​​atomized and carried away as a mist, ultimately entering the external environment through the mouthpiece 110; the second direction is from the bottom of the atomizer cover 320 into the internal cavity, and then flows into the liquid storage cavity through the auxiliary air flow structure 322 on the side wall of the atomizer cover 320, thereby balancing the air pressure between the liquid storage cavity and the main atomization duct (which is connected to the external environment); the third direction is from the bottom of the package cover into the main atomization duct, then flows into the internal cavity again through the auxiliary air flow holes 323 on the side wall of the atomizer cover 320, and then flows into the liquid storage cavity through the auxiliary air flow structure 322 on the side wall of the atomizer cover 320.

[0071] One end of the auxiliary air passage structure 322 is connected to the liquid inlet 321, and the other end is connected to the auxiliary air hole 323. Airflow in the second and third directions flows through the auxiliary air passage structure 322 on the side wall of the atomizing hood 320 into the liquid storage chamber, thereby balancing the air pressure between the liquid storage chamber and the main atomization channel (which is connected to the external environment), thereby ensuring that the aerosol matrix can smoothly pass through the liquid inlet 321 and be immersed in the liquid guide 340.

[0072] In addition, part of the airflow in the second flow direction and the third flow direction will flow into the main atomization channel from the liquid inlet 321. During this process, part of the airflow in the second flow direction and the third flow direction can carry part of the aerosol matrix and immerse into the liquid guiding liquid 340, thereby quickly replenishing the aerosol matrix in the liquid guiding liquid 340 and avoiding the occurrence of wick burning.

[0073] The atomizing device 10 also includes a sealing member 360, which is hollow and arranged inside the housing 100 and fixedly connected to the housing 100. The sealing member 360 can be threaded and interference-connected to the housing 100. The inner wall of the sealing member 360 contacts the outer wall of the atomizing cover 320, surrounds the atomizing cover 320, and is used to seal the bottom of the liquid storage chamber to prevent the aerosol matrix from leaking out from the bottom of the liquid storage chamber. The width of the sealing member 360 is greater than the width of the liquid inlet 321. Before the user uses it for the first time, the sealing member 360 seals the bottom of the liquid storage chamber while also sealing the liquid inlet 321, separating the aerosol matrix in the liquid storage chamber and the atomizing core assembly. The sealing member 360 is arranged to slide and seal with the atomizing cover 320. During use, the sealing member 360 and the atomizing cover 320 move relative to each other. The sealing member 360 seals the liquid storage cavity while opening the liquid inlet 321 , and the aerosol matrix flows from the liquid storage cavity into the atomizing cover 320 through the liquid inlet 321 .

[0074] The seal 360 is an annular structure, and the auxiliary air flow structure 322 is a groove structure. The inner wall of the annular seal 360 fits tightly against the sidewall of the atomizing hood 320, allowing the auxiliary air flow structure 322 and seal 360 to close together to form an auxiliary airway. One end of the auxiliary airway is connected to the external environment, and the other end is connected to the liquid storage chamber. This allows airflow to enter the liquid storage chamber to balance the internal and external air pressures. In the non-inhalation state, the auxiliary air flow structure 322 can partially enter the auxiliary airway through capillary action and be adsorbed within the auxiliary airway, thereby ensuring that the aerosol matrix in the oil storage chamber does not leak along the sidewall of the atomizing hood 320.

[0075] The seal 360 is provided with a support member 380, and the support member 380 is fixedly connected to the seal 360. The support member 380 and the seal 360 are integrally formed by in-mold injection molding. The support member 380 is made of a hard material, including but not limited to PP, PE or metal. A limiting portion is provided in the shell 100 (at the same position as the support member 380 in the figure), and the support member 380 abuts against the limiting portion to fix the connection between the seal 360 and the shell 100. Since the seal 360 is made of a material with a certain elasticity, it requires external support to fix the position. Compared with the traditional support frame, the integration of the support member 380 and the seal 360 in this embodiment makes the structure more compact, saves the assembly time of one component in the production process, and at the same time, produces one less component, reduces the production cost, and facilitates automated production.

[0076] In some embodiments, an air inlet 210 is provided on the bottom wall of the package body 200 , and the air inlet 210 is used to connect the internal cavity with the external environment.

[0077] By setting an air inlet hole 210 penetrating the bottom wall of the packaging base body 200, external air can flow in from the air inlet hole 210 during the user's inhalation process, thereby ensuring sufficient air flow in the first flow direction, the second flow direction, and the third flow direction.

[0078] A boss is formed on the bottom wall of the package base 200 along the axial direction, and an air inlet hole 210 is formed through the boss. While ensuring a smooth air passage, the boss structure can prevent condensation backflow or leakage of aerosol matrix from flowing out of the bottom of the atomizer 10, thereby ensuring that the working circuit is not contaminated or corroded by the leaked aerosol matrix.

[0079] In one embodiment, the atomizing device 10 includes a sealing ring 310. The sealing ring 310 is disposed between the atomizing pipe (not labeled) and the atomizing cover 320. This seals the connection between the atomizing pipe (not labeled) and the atomizing cover 320 and prevents the aerosol matrix in the liquid storage chamber from escaping through the gap between the two. Silicone can be used as the material of the sealing ring 310.

[0080] The atomizing device 10 includes an atomizing core, which is arranged in the atomizing cover 320 and is configured to atomize the aerosol matrix in the liquid storage chamber. The atomizing core includes a heating element 350 and a liquid guide 340. The heating element 350 is sleeved in the liquid guide 340, and the liquid guide 340 is sleeved inside the atomizing cover 320. The liquid guide is hollow and is used to guide the aerosol matrix flowing into the atomizing chamber in the second liquid storage state, while preventing the aerosol matrix from excessively flowing into the atomizing chamber after the liquid inlet 321 is opened, causing splashing when the heating element is working, and scalding the user. The heating element 350 is arranged close to the inner wall of the liquid guide 340, and the liquid guide 340 is arranged close to the inner wall of the atomizing cover 320.

[0081] The liquid guide 340 is used to directly absorb and conduct the aerosol matrix that enters the atomizer core from the liquid storage chamber through the liquid inlet hole, thereby allowing the aerosol matrix to contact the heating element 350. When the heating element 350 is energized, the aerosol matrix in the liquid storage element is heated and evaporated into a vapor or aerosol, which is then provided to the user for inhalation. The material of the liquid guide 340 can be made of oil-conducting cotton or porous ceramic material. While it plays a better role in conducting the aerosol matrix, it can also withstand the high temperature generated when the heating element 350 is in operation. The heating element 350 includes a heating section and pins. The heating section is used to heat the aerosol matrix. The pins are connected to the heating section and can be set at both ends of the heating section to connect to a power supply device to conduct current to the heating section. The pins include a first pin (not shown) and a second pin (not shown).

[0082] In some embodiments, the atomizer device 10 further includes an absorbent liquid 330 disposed on one side of the atomizer core. The absorbent liquid is housed within the atomizer housing 320 and positioned between the atomizer pipe and the atomizer core. It is used to absorb condensed liquid flowing down the atomizer pipe, preventing it from falling into the liquid guide 340 and being heated again by the heating element 350 to generate aerosol, which would otherwise affect the user's puffing experience.

[0083] 6 to 12 , the present invention also provides an atomizing device 10, which includes a housing 100, one end of which is open and the other end of which is provided with an atomizing pipe 370 extending inward; an atomizing cover 320 such as any of the above embodiments, the atomizing cover 320 is connected to the atomizing pipe 370; a sealing member 360 is connected to the housing 100 and the atomizing cover 320, so that the sealing member 360, the housing 100, and the atomizing cover 320 form a liquid storage chamber; wherein the sealing member 360 is connected to the housing 100 and the atomizing cover 320; The component 360 is movably connected to the atomizing cover 320 to form a first liquid storage state or a second liquid storage state; the atomizing core is arranged in the atomizing cover 320 and is configured to be an aerosol matrix of the atomizing liquid storage chamber; wherein, in the second liquid storage state, the liquid inlet 321 of the atomizing cover 320 is connected to the liquid storage chamber and the atomizing core; the auxiliary air passage structure 322 is connected to the sealing component 360 to form an auxiliary airway, one end of the auxiliary air passage structure 322 is used to connect to the liquid storage chamber, and the other end of the auxiliary air passage structure 322 is used to connect to the external environment.

[0084] As shown in Figure 6 , the atomizer 10 is in the first liquid storage state (inactive state). The inner wall of the annular sealing body fits tightly against the liquid inlet of the atomizer cover 320, preventing leakage of the aerosol matrix. The atomizer 10 is switched from the first liquid storage state to the second liquid storage state by pushing the package base 200 axially.

[0085] Please refer to Figures 6 and 11. When the packaging base 200 is quickly pushed, the hydraulic pressure in the liquid storage chamber will increase instantaneously, forcing the aerosol matrix in the liquid storage chamber to quickly immerse into the liquid guide 340 through the liquid inlet 321, thereby achieving rapid core lubrication in a very short time, avoiding the user from inhaling when the atomizer 10 is not lubricated, resulting in a "core sticking" situation.

[0086] During the process of rapidly pushing the packaging seat 200, the air pressure in the internal cavity increases, forcing the gas to enter the liquid storage cavity through the second flow direction to balance the air pressure between the liquid storage cavity and the main atomization path, thereby preventing the internal air pressure from being lower than the external air pressure, causing the aerosol matrix to be unable to quickly enter the liquid guide 340.

[0087] Furthermore, by increasing the overall length of the auxiliary ventilation structure 322 through bending, the viscosity of the aerosol matrix, the external air pressure, and the air pressure within the liquid storage chamber are balanced, preventing the aerosol matrix from flowing from the auxiliary ventilation structure 322 into the internal cavity. Furthermore, when the package base 200 is rapidly pushed, the air pressure within the internal cavity increases instantaneously, forcing the gas originally within the auxiliary ventilation structure 322 to enter the liquid inlet 321, entraining the aerosol matrix.

[0088] By rapidly pushing the package base 200, the atomizer device 10 transitions from the first liquid storage state to the second liquid storage state, allowing the aerosol matrix within the liquid storage chamber to penetrate the inhalation liquid within the atomizer hood 320 through the liquid inlet 321. As shown in Figure 11, when the atomizer device 10 is in the second liquid storage state (activated state), airflow from the surrounding environment flows into the internal chamber through the air inlet 210 on the bottom wall of the package base 200. The internal airflow is primarily divided into three directions. The first direction is from the bottom of the package hood into the main atomization channel, where the aerosol matrix is ​​atomized and carried away as a mist, ultimately entering the external environment through the inhaler nozzle 110. The second direction is from the bottom of the atomizer hood 320 into the internal chamber, passing through the auxiliary air passage structure 322 on the side wall of the atomizer hood 320 to the liquid storage chamber, thereby balancing the air pressure between the liquid storage chamber and the main atomization channel (which is connected to the external environment). The third flow direction is that after entering the main atomization channel from the bottom of the packaging cover, the air flow passes through the auxiliary air holes 323 on the side wall of the atomization cover 320 and flows into the internal cavity again, and then flows into the liquid storage cavity through the auxiliary air flow structure 322 on the side wall of the atomization cover 320.

[0089] One end of the auxiliary air passage structure 322 is connected to the liquid inlet 321, and the other end is connected to the auxiliary air hole 323. Airflow in the second and third directions flows through the auxiliary air passage structure 322 on the side wall of the atomizing hood 320 into the liquid storage chamber, thereby balancing the air pressure between the liquid storage chamber and the main atomization channel (which is connected to the external environment), thereby ensuring that the aerosol matrix can smoothly pass through the liquid inlet 321 and be immersed in the liquid guide 340.

[0090] In addition, part of the airflow in the second flow direction and the third flow direction will flow into the main atomization channel from the liquid inlet 321. During this process, part of the airflow in the second flow direction and the third flow direction can carry part of the aerosol matrix and immerse into the liquid guiding liquid 340, thereby quickly replenishing the aerosol matrix in the liquid guiding liquid 340 and avoiding the occurrence of wick burning.

[0091] In some embodiments, an air inlet 210 is provided on the bottom wall of the package body 200 , and the air inlet 210 is used to connect the internal cavity with the external environment.

[0092] By setting an air inlet hole 210 penetrating the bottom wall of the packaging base body 200, external air can flow in from the air inlet hole 210 during the user's inhalation process, thereby ensuring sufficient air flow in the first flow direction, the second flow direction, and the third flow direction.

[0093] A boss is formed on the bottom wall of the package base 200 along the axial direction, and an air inlet hole 210 is formed through the boss. While ensuring a smooth air passage, the boss structure can prevent condensation backflow or leakage of aerosol matrix from flowing out of the bottom of the atomizer 10, thereby ensuring that the working circuit is not contaminated or corroded by the leaked aerosol matrix.

[0094] An embodiment of the present application further provides an atomization device, comprising the atomization device 10 in any one of the above embodiments, wherein the atomization device 10 is electrically connected to a power supply device.

[0095] In this embodiment, an auxiliary air passage structure 322 is provided on the side wall of the atomizing hood 320. During the user's inhalation process, the auxiliary air passage structure 322 can connect the liquid storage chamber with the external environment, thereby balancing the external air pressure and the air pressure in the liquid storage chamber, so that the aerosol matrix can quickly penetrate into the atomizing core provided in the internal channel of the atomizing hood 320 through the liquid inlet 321.

[0096] During the process of rapidly pushing the package base 200, the hydraulic pressure in the liquid storage chamber will increase instantaneously, forcing the aerosol matrix in the liquid storage chamber to quickly immerse into the liquid guide 340 through the liquid inlet 321, thereby achieving rapid core lubrication in a very short time (core lubrication can be completed in only 2 to 3 seconds), avoiding the user from inhaling when the atomizer 10 is not lubricated, resulting in a "core sticking" situation.

[0097] The atomizer 10 also includes a conductive element. One end of the conductive element is located on the side of the package body 200 near the atomizer core and is electrically connected to the heating element via a pin. The other end of the conductive element is exposed to the air on the side of the package body 200 and can contact the conductive connector on the power supply device to establish an electrical connection with the power supply device, thereby supplying power from the power supply device to the heating element, thereby heating and atomizing the aerosol.

[0098] In one embodiment, the conductive element and package base 200 are integrally formed using in-mold injection molding. Specifically, the conductive element is first placed into a mold for the package base 200, resulting in an integrated production of the conductive element and package base 200. The conductive element can be an electrode column or an electrode sheet, and is made of a metal with good conductivity. In this embodiment, the package base 200 is made of an insulating material.

[0099] In one embodiment, the conductive member may be an electrode sheet, and the package base 200 may be provided with a support column located at one end of the package base 200 near the heating element to support the conductive member. In this embodiment, the provision of an electrode sheet saves more metal material than an electrode column, thereby reducing production costs.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
