Description

Technical Field

[0001] The present application belongs to the technical field of aerosol generation, and more specifically, to an atomization component and an aerosol generating device. Background Art

[0002] The atomizer assembly generally has a night storage chamber. Under the premise of ensuring the sealing of the structure, the night storage chamber generally has two air inlet channels, namely the porous atomizer core and the ventilation channel. When the night storage chamber is filled with oil, the atomizer core generally absorbs the atomized medium to generate a certain negative pressure in the night storage chamber to lock the atomized medium, or the atomized medium leaked from the night storage chamber to the ventilation channel is stored through the ventilation channel. However, when the air pressure in the night storage chamber fluctuates greatly due to temperature, it will cause a large positive pressure difference between the night storage chamber and the ventilation channel. The positive pressure difference will squeeze out the atomized medium stored in the ventilation channel, and eventually cause oil leakage. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide an atomization component and an aerosol generating device to solve the technical problem in the prior art that when a large air pressure fluctuation occurs in the storage chamber due to temperature influence, the atomized medium stored in the ventilation channel will be squeezed out and oil leakage will occur.

[0004] To achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide an atomization assembly, including a shell; a night storage chamber is formed in the shell; the night storage chamber is used to accommodate an atomization medium; an absorption structure is provided in the night storage chamber; the absorption structure is arranged to be spaced apart from the atomization medium; the absorption structure is used to absorb oxygen or nitrogen in the air in the night storage chamber.

[0005] In one possible design, the absorption rate of the absorbent structure increases with increasing temperature.

[0006] In one possible design, the absorbent structure is a deoxidizer.

[0007] In one possible design, the deoxidizer includes one or more of reduced iron powder, activated carbon, diatomaceous earth, calcium oxide, magnesium oxide, aluminum oxide, potassium oxide, calcium chloride, sodium sulfate, potassium chloride, ferrous sulfate, sodium sulfide, and copper sulfate.

[0008] In a possible design, the absorbent structure is disposed on the top of the night storage cavity.

[0009] In a possible design, the space between the absorption structure and the atomized medium is assumed to be a gas space; along the axial direction of the shell, the projection of the absorption structure coincides with the projection of the gas space.

[0010] In a possible design, an atomization chamber connected to the external atmosphere is also formed in the shell; a porous atomization core is provided in the atomization chamber; the night storage chamber is connected to the atomization chamber through the atomization core; the atomization assembly also includes a ventilation channel connected to the night storage chamber; the ventilation threshold of the ventilation channel is lower than the ventilation threshold of the atomization core.

[0011] In a possible design, a partition is further provided in the storage chamber; the partition is used to separate the absorption structure from the atomization medium; the partition can allow gas to pass through; and the partition can block liquid from passing through.

[0012] In a possible design, the isolation element is a breathable and oleophobic structure.

[0013] The beneficial effect of the atomizer assembly provided by the present application is that: the atomizer assembly provided by the embodiment of the present application, by arranging an absorption structure in the night storage chamber, when the temperature in the night storage chamber decreases, according to the ideal gas state equation, PV = nRT, wherein P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n represents the amount of gas substance, T represents the thermodynamic temperature of the ideal gas, and R is the ideal gas constant. It can be seen from the above formula that temperature and pressure are proportional. When the temperature decreases, the gas pressure in the night storage chamber will decrease. The temperature drops, causing the pressure in the night storage chamber to drop to exceed the ventilation threshold of the ventilation channel, and the external gas enters the night storage chamber through the ventilation channel, and the amount of gas in the cavity increases, that is, n increases. However, the absorption structure will absorb oxygen or nitrogen in the air entering the night storage chamber, that is, reduce the amount of air n, so that the pressure in the night storage chamber is maintained above the ventilation threshold of the ventilation channel. At this time, no ventilation will be performed, and the pressure value in the night storage chamber will not exceed the external air pressure, and no oil leakage will occur. When the temperature in the night storage chamber rises, according to the ideal gas state equation, it can be seen that as the temperature rises, the pressure in the night storage chamber rises. At this time, the atomized medium in the night storage chamber may be squeezed into the ventilation channel. However, as the temperature rises, the absorption structure can still continue to absorb oxygen or nitrogen in the air in the night storage chamber, thereby controlling the increase in pressure in the night storage chamber, so that the atomized medium in the ventilation channel can be sucked back into the night storage chamber, thereby reducing the occurrence of oil leakage. In general, even if the night storage chamber produces a large pressure fluctuation due to the influence of temperature, it will not cause the atomized medium stored in the ventilation channel to be squeezed out and cause oil leakage.

[0014] On the other hand, the present application also provides an aerosol generating device, including a power supply structure and the above-mentioned atomization component; the power supply structure supplies power to the atomization component.

[0015] The beneficial effect of the aerosol generating device provided by the present application is that the aerosol generating device provided by the embodiment of the present application can reduce the oil leakage of the aerosol generating device through the design of the above-mentioned atomization component.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Under the premise of ensuring the sealing of the structure, the night storage chamber generally has two air inlet channels, namely the porous atomizer core and the ventilation channel. When the night storage chamber is filled with oil, the atomizer core generally absorbs the atomizer medium to generate a certain negative pressure in the night storage chamber to lock the atomizer medium, or the atomizer medium leaked from the night storage chamber to the ventilation channel is stored through the ventilation channel. However, when the air pressure in the night storage chamber fluctuates greatly due to the influence of temperature, it will cause a large positive pressure difference between the night storage chamber and the ventilation channel. The positive pressure difference will squeeze out the atomizer medium stored in the ventilation channel, and eventually cause oil leakage.

[0026] In order to solve the above problems, the inventors of the present application, after a long period of in-depth research, finally provided an atomization assembly and an aerosol generating device, in which an absorption structure is arranged in the shell, and the oxygen or nitrogen in the air in the storage chamber is absorbed by the absorption structure, thereby reducing the air pressure in the storage chamber and alleviating oil leakage.

[0027] See also Figure 1 The embodiment of the present application provides an aerosol generating device, including a power supply structure 200 and an atomizing assembly 100. The power supply structure 200 is mechanically and electrically connected to the atomizing assembly 100. The power supply structure 200 is used to supply power to the atomizing assembly 100. The atomizing assembly 100 is used to atomize the atomizing medium 150 into aerosol particles.

[0028] See also Figure 2 The atomization assembly 100 includes a shell 110; a storage chamber (not shown in the figure) is formed in the shell 110; the storage chamber is used to accommodate an atomizing medium 150; an absorption structure 120 is provided in the storage chamber; the absorption structure 120 is arranged to be spaced apart from the atomizing medium 150; the absorption structure 120 is used to absorb oxygen or nitrogen in the air in the storage chamber.

[0029] The atomizing medium 150 is flowable smoke liquid.

[0030] The absorption structure 120 is arranged to be spaced apart from the atomized medium 150. When the atomized medium 150 is injected into the storage chamber, there is a space between the absorption structure 120 and the atomized medium 150. The space is assumed to be Figure 2 The gas space 111 in the.

[0031] When the atomized medium 150 is injected into the night storage chamber, the atomized medium 150 in the night storage chamber will be mixed with air, and the gas space 111 will also be filled with air; the absorption structure 120 will absorb the oxygen or nitrogen in the air in the atomized medium 150 and the air in the gas space 111.

[0032] Air is composed of nitrogen, oxygen, rare gases (helium, neon, argon, krypton, xenon, radon), carbon dioxide and other substances (such as water vapor, impurities, etc.). Among them, the volume fraction of nitrogen is about 78%, the volume fraction of oxygen is about 21%, the volume fraction of rare gases (helium, neon, argon, krypton, xenon, radon) is 0.934%, the volume fraction of carbon dioxide is 0.04%, and the volume fraction of other substances (such as water vapor, impurities, etc.) is about 0.002%. The oxygen or nitrogen in the air in the storage chamber is absorbed by the absorption structure 120. According to the law of partial pressure of gas pressure, the partial pressure generated by a certain gas in the gas mixture is equal to the pressure generated when it occupies the entire container alone; and the total pressure of the gas mixture is equal to the sum of the partial pressures of each gas therein. Therefore, when the oxygen or nitrogen in the air is absorbed, the pressure of the air will decrease, thereby reducing the occurrence of oil leakage.

[0033] When the air pressure in the night storage chamber fluctuates greatly due to the influence of temperature. Specifically, when the temperature in the night storage chamber decreases, according to the ideal gas state equation, PV=nRT, where P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n represents the amount of gas substance, T represents the thermodynamic temperature of the ideal gas, and R is the ideal gas constant. It can be seen from the above formula that temperature and pressure are proportional. When the temperature decreases by 1°C, the gas pressure in the night storage chamber will drop by 338Pa. The temperature drops, causing the pressure in the night storage chamber to drop to a level exceeding the ventilation threshold of the ventilation channel. External gas enters the night storage chamber through the ventilation channel, and the amount of gas in the cavity increases, that is, n increases. However, the absorption structure 120 will absorb oxygen or nitrogen in the air entering the night storage chamber, that is, reduce the amount of air n, so that the pressure in the night storage chamber is maintained above the ventilation threshold of the ventilation channel. At this time, no ventilation will be carried out, and the pressure value in the night storage chamber will not exceed the external air pressure, and no oil leakage will occur. When the temperature in the storage chamber rises, according to the ideal gas state equation, it can be seen that the temperature rises and the pressure in the storage chamber rises. At this time, the atomized medium 150 in the storage chamber may be squeezed into the ventilation channel. However, when the temperature rises, the absorption structure 120 can still continue to absorb oxygen or nitrogen in the air in the storage chamber, thereby controlling the increase in pressure in the storage chamber, so that the atomized medium 150 in the ventilation channel can be sucked back into the storage chamber, thereby reducing the occurrence of oil leakage. In addition, the atomization assembly 100 is applicable to a wide range of viscosities of the atomized medium 150, from low viscosity to high viscosity.

[0034] It should be noted that the ventilation threshold means that when the difference between the external air pressure and the air pressure in the storage chamber reaches the ventilation threshold, the channel corresponding to the ventilation threshold will be ventilated.

[0035] In actual application, the atomizer assembly 100 is prone to oil leakage in the following three situations: 1. Shelving during the day and night; 2. Large-volume suction; 3. Transport temperature shock. The following is an analysis and comparison of these three situations before and after using the absorption structure.

[0036] 1. Use the absorption structure 120 to solve the problem of liquid leakage when stored: Due to the temperature difference between day and night, when the temperature drops at night, the pressure in the night storage cavity drops to a level that exceeds the ventilation threshold of the ventilation channel. The external gas enters the night storage cavity through the ventilation channel, and the amount of gas in the cavity increases, that is, n increases, and the pressure in the night storage cavity rises at the same time; during the day, due to the increase in the amount and temperature of the gas in the cavity, the pressure in the night storage cavity further increases and even exceeds the external air pressure, causing liquid leakage. The use of the absorption structure 120 in the embodiment of the present application means that when the temperature drops at night, the pressure in the night storage chamber drops to the ventilation threshold, causing gas to enter from the ventilation channel. The absorption structure 120 will absorb the components of the air entering the night storage chamber, that is, reduce the amount of gas n, so that the pressure in the night storage chamber is maintained above the ventilation threshold, and the pressure value in the night storage chamber will not exceed the external air pressure, and oil leakage will not occur; during the day, the temperature rises, and the absorption structure 120 controls the amount of gas entering the night storage chamber at night. At the same time, the absorption structure 120 continues to work when the temperature rises, thereby controlling the pressure rise in the night storage chamber and avoiding the occurrence of liquid leakage when left idle.

[0037] 2. Use the absorption structure 120 to solve the problem of leakage during large-volume puffing: With prolonged puffing, the temperature in the night storage chamber rises due to heat conduction, and in the later stage of puffing, the amount of gas in the night storage chamber increases due to the previous ventilation, which causes the pressure in the night storage chamber to rise and even exceed the external air pressure, causing leakage during puffing. The use of the absorption structure 120 can absorb the components of the air entering the night storage chamber during the previous ventilation, reduce the amount of gas in the night storage chamber, and increase the initial negative pressure in the later stage of puffing. Even if the temperature of the night storage chamber rises due to puffing, the increase in the initial negative pressure and the continuous operation of the absorption structure 120 can prevent the occurrence of leakage of the night storage chamber oil during puffing.

[0038] 3. Use the absorption structure 120 to solve the problem of leakage during transportation temperature shock: This principle is the same as the leakage when left idle during the day and night. When the temperature drops, the absorption structure 120 is used, and the pressure in the night storage chamber drops to the ventilation threshold, causing gas to enter from the ventilation channel, but the absorption structure 120 will absorb the combined components of the air entering the night storage chamber, that is, reduce the amount of gas n, so that the pressure in the night storage chamber is maintained above the ventilation threshold; when the temperature rises, the absorption structure 120 controls the amount of gas entering the night storage chamber at low temperature. At the same time, when the temperature rises, the absorption structure 120 continues to work, thereby controlling the pressure rise in the night storage chamber and avoiding the occurrence of leakage.

[0039] In one embodiment, the absorption rate of the absorption structure 120 increases with the increase of temperature. Therefore, when the temperature in the liquid storage cavity rises, the absorption structure 120 can quickly absorb the oxygen or nitrogen in the air in the liquid storage cavity, and can quickly reduce the air pressure in the liquid storage cavity, thereby reducing leakage.

[0040] In one embodiment, factors affecting the absorption of components in the air by the absorption structure 120 include: temperature, humidity, surface area of ​​the absorption structure 120, concentration of the components in the air, and type of the absorption structure 120. Generally speaking, the higher the temperature, the more concentrated the components in the air, and the larger the surface area of ​​the absorption structure 120 in contact with the air, the faster the absorption structure 120 absorbs the components; the higher the humidity, the slower the absorption structure 120 absorbs the components.

[0041] In one embodiment, the absorption structure 120 is used to absorb oxygen in the air in the storage chamber. Since the volume fraction of oxygen in the air is about 21%, when the absorption structure 120 absorbs all the oxygen in the air in the cavity, the pressure in the storage chamber will be reduced by 21%, thereby effectively reducing the oil leakage of the storage chamber.

[0042] In one embodiment, the absorption structure 120 is a deoxidizer. The deoxidizer is arranged in the night storage chamber to absorb oxygen entering the night storage chamber, so that the night storage chamber is in an oxygen-free state. In this way, not only can the negative pressure difference between the air pressure in the night storage chamber and the air pressure of the external environment be maintained at a high level, but the liquid in the atomizer core 140 can be better locked, and the leakage of the ventilation channel can be reduced; in addition, the smoke oil or high-viscosity cannabis oil is susceptible to temperature, light, moisture, and oxygen. Deterioration occurs, especially the active ingredients in the high-viscosity cannabis oil are gradually oxidized and decomposed under aerobic conditions, reducing its effectiveness and destroying its flavor and taste. Therefore, the deoxidation of the deoxidizer has an anti-mildew effect, which can prevent the smoke oil or high-viscosity cannabis oil from deteriorating during long-term storage. It can be understood that in other embodiments of the present application, the absorption structure 120 can also be other structures that can absorb oxygen, such as a membrane or absorption liquid that can absorb oxygen.

[0043] In one embodiment, the deoxidizer includes one or more of reduced iron powder, activated carbon, diatomaceous earth, calcium oxide, magnesium oxide, aluminum oxide, potassium oxide, calcium chloride, sodium sulfate, potassium chloride, ferrous sulfate, sodium sulfide, and copper sulfate. Reduced iron powder, activated carbon, diatomaceous earth, calcium oxide, magnesium oxide, aluminum oxide, potassium oxide, calcium chloride, sodium sulfate, potassium chloride, ferrous sulfate, sodium sulfide, and copper sulfate all have the function of absorbing oxygen. The deoxidizer can be made of any one of reduced iron powder, activated carbon, diatomaceous earth, calcium oxide, magnesium oxide, aluminum oxide, potassium oxide, calcium chloride, sodium sulfate, potassium chloride, ferrous sulfate, sodium sulfide, and copper sulfate. The deoxidizer can also be mixed by reducing two or more of iron powder, activated carbon, diatomaceous earth, calcium oxide, magnesium oxide, aluminum oxide, potassium oxide, calcium chloride, sodium sulfate, potassium chloride, ferrous sulfate, sodium sulfide, and copper sulfate, and made according to each specific ratio, which is not limited here.

[0044] In one embodiment, the factors affecting the oxygen absorption rate of the deoxidizer include temperature, humidity, oxygen concentration, type of deoxidizer, surface area of ​​contact between the deoxidizer and air, concentration of chemical reactants, and properties of reactants. The higher the temperature, the higher the oxygen concentration, the larger the surface area of ​​contact with air, and the higher the concentration of active ingredients in the deoxidizer, the faster the reaction rate; the higher the humidity, the slower the reaction rate; in addition, different types of deoxidizers have different reaction rates due to the different active ingredients contained therein.

[0045] In one embodiment, see Figure 2 , the absorption structure 120 is arranged at the top of the night storage chamber. During assembly, the absorption structure 120 can be installed on the top of the night storage chamber first, and then the atomizing medium 150 is injected into the night storage chamber, and it is ensured that there is a certain volume of gas space 111 between the atomizing medium 150 and the absorption structure 120. Alternatively, the atomizing medium 150 can be injected into the night storage chamber first, and then the absorption structure 120 is installed above the atomizing medium 150. In this embodiment, since the atomizing medium 150 is tobacco oil, the tobacco oil will flow to a lower place under the action of gravity. When the absorption structure 120 is arranged at the top of the night storage chamber, it can accommodate enough tobacco oil under the condition that the total volume of the night storage chamber is certain, and the space of the night storage chamber can be fully utilized, which is conducive to miniaturization design.

[0046] In one embodiment, see Figure 2 , the absorption structure 120 and the gas space 111 are arranged vertically opposite to each other; in the axial direction of the shell 110, the projection of the absorption structure 120 coincides with the projection of the gas space 111. That is, along the axial direction of the shell 110, the absorption structure 120 and the gas space 111 are arranged correspondingly at any position, so that the absorption structure 120 can fully contact the air in the gas space 111, achieving a higher oxygen absorption speed.

[0047] In one embodiment, see Figure 2 The housing 110 also forms an atomizing chamber 112 connected to the outside atmosphere; a porous atomizing core 140 is provided in the atomizing chamber 112; the night storage chamber is connected to the atomizing chamber 112 through the atomizing core 140; the atomizing assembly 100 also includes a ventilation channel connected to the night storage chamber. The ventilation threshold of the ventilation channel is lower than the ventilation threshold of the atomizing core 140.

[0048] It should be noted here that the ventilation threshold means that when the difference between the external air pressure and the air pressure in the night storage chamber reaches the ventilation threshold, the channel corresponding to the ventilation threshold will be ventilated. For example, when the ventilation threshold of the ventilation channel is set to 600Pa, the ventilation threshold of the atomizer core 140 is set to 1000Pa. Then when the difference between the external air pressure and the air pressure in the night storage chamber reaches 600Pa, the night storage chamber can be ventilated through the ventilation channel, and the external atmosphere can enter the night storage chamber through the ventilation channel to promote the fluidity of the smoke oil in the night storage chamber, but at this time, the atomizer core 140 will not be ventilated, that is, the smoke oil in the night storage chamber can enter the atomizer core 140, but the gas in the atomizer chamber 112 cannot enter the night storage chamber through the atomizer core 140. In the embodiment of the present application, by setting the ventilation threshold of the ventilation channel to be smaller than the ventilation threshold of the atomizer core 140, the storage chamber is mainly ventilated through the ventilation channel, reducing the atomizer core 140 from being used for ventilation while atomizing, avoiding dry burning that affects the taste and reduces the lifespan.

[0049] In addition, the ventilation threshold of the ventilation channel needs to be selected according to the liquid supply of the atomizer core 140. When the liquid supply capacity of the atomizer core 140 is strong, that is, the liquid supply of the atomizer core 140 is smooth, the ventilation threshold of the ventilation channel can be designed to be higher. When the liquid supply capacity of the atomizer core 140 is weak, that is, the liquid supply of the atomizer core 140 is not smooth, the ventilation threshold of the ventilation channel can be designed to be lower. That is, it is necessary to design ventilation channels with different ventilation thresholds for different atomizer cores 140.

[0050] The liquid supply capacity of the atomizer core 140 is generally related to the inner diameter, length and number of the holes in the atomizer core 140. The ventilation threshold of the ventilation channel is related to the length and inner diameter of the ventilation channel.

[0051] In addition, the ventilation threshold design of the ventilation channel also needs to meet the requirement that the negative pressure of the night storage chamber after ventilation can maintain the gravity of the smoke oil in the night storage chamber to prevent oil leakage. When the night storage chamber is ventilated, the night storage chamber may generate positive pressure when it is at high temperature. At this time, the smoke oil in the night storage chamber will leak from the ventilation channel. Therefore, the ventilation channel needs to be long enough to prevent the smoke oil from leaking from the ventilation channel, so as to ensure that it can be sucked back into the night storage chamber when the pressure in the night storage chamber is restored.

[0052] In one embodiment, one end of the ventilation channel is connected to the night storage chamber, and the other end of the ventilation channel is connected to the atomizing chamber 112, that is, ventilation is achieved by conducting the gas in the atomizing chamber 112 to the night storage chamber. In other embodiments, one end of the ventilation channel may be connected to the night storage chamber, and the other end of the ventilation channel may be connected to the external atmosphere, and ventilation is achieved by directly introducing the external atmosphere into the night storage chamber.

[0053] In one embodiment, see Figure 2 The night storage chamber is arranged around the atomization chamber 112 , the absorption structure 120 is arranged around the atomization chamber 112 , and the gas space 111 is arranged around the atomization chamber 112 .

[0054] In one embodiment, the atomizer core 140 is electrically connected to the power supply structure 200. The e-liquid in the storage chamber flows through the atomizer core 140, and the atomizer core 140 heats the e-liquid and atomizes it into aerosol particles.

[0055] In one embodiment, see Figure 2 The shell 110 is connected to a mouthpiece 160 ; the mouthpiece 160 is communicated with the atomization chamber 112 .

[0056] In one embodiment, the amount of deoxidizer is related to the amount of oxygen absorbed. 2.2g of deoxidizer can absorb 240ml of oxygen, and the gram weight of the deoxidizer is linearly related to the amount of oxygen absorbed, that is, 240ml / 2.2g*0.1g=10.9ml of oxygen. In addition, the amount of deoxidizer used is related to the injection volume of the atomizing medium. For example, if the injection volume is 2ml, 0.02g of deoxidizer is theoretically required. Of course, a certain amount of interference can be appropriately increased for the deoxygenation speed. The present application can achieve a negative pressure that meets the design requirements in the night storage chamber by adjusting the gram weight of the deoxidizer and matching the night storage chamber space. This design can avoid complex direct liquid structure design and calculation, and the design is simpler and the cost is lower.

[0057] In one embodiment, see Figure 2 The storage chamber is also provided with a separator 130; the separator 130 is used to separate the absorption structure 120 from the atomization medium 150; the separator 130 can allow gas to pass through; the separator 130 can block liquid from passing through. The air in the gas space 111 can pass through the separator 130 to be partially absorbed by the absorption structure 120, and the smoke oil in the storage chamber is blocked by the separator 130, thereby preventing the smoke oil from increasing the humidity of the absorption structure 120 and preventing the smoke oil from affecting the absorption capacity of the absorption structure 120.

[0058] In one embodiment, the spacer 130 is an air-permeable and oleophobic structure. Gas can pass through the air-permeable and oleophobic structure, but smoke oil cannot pass through the air-permeable and oleophobic structure. Specifically, the air-permeable and oleophobic structure can be formed by stacking multiple layers of thin film materials, and the pore size of the material is designed so that the pore size can only allow air flow to pass through, but not oil to pass through; in addition, an oleophobic layer needs to be designed on the surface of the air-permeable and oleophobic structure to reduce the accumulation of smoke oil on the surface of the air-permeable and oleophobic structure.

[0059] In one embodiment, see Figure 2 The isolation member 130 is disposed below the absorption structure 120 , and the absorption structure 120 is isolated from the atomized medium 150 by the isolation member 130 .

[0060] In one embodiment, see Figure 2 The isolation member 130 is supported below the absorption structure 120 , and the absorption structure 120 can be supported by the isolation member 130 .

[0061] In one embodiment, a limiting member is formed on the inner wall of the storage cavity, and the isolation member 130 is limited by the limiting member to achieve the installation of the absorption structure 120 and the isolation member 130.

[0062] In another embodiment of the present application, the absorption structure 120 is used to absorb oxygen and rare gases in the air in the storage chamber. Since the volume fraction of oxygen in the air is about 21%, and the volume fraction of rare gases is 0.934%, when the absorption structure 120 absorbs all the oxygen and rare gases in the air in the cavity, the pressure in the storage chamber will be reduced by 21.934%, thereby effectively reducing the oil leakage of the storage chamber.

[0063] In another embodiment of the present application, the absorption structure 120 is used to absorb the rare gas in the air in the storage chamber. Although the volume of the rare gas accounts for a small proportion, it can also reduce the pressure in the storage chamber and reduce the oil leakage of the storage chamber to a certain extent.

[0064] In another embodiment of the present application, the absorption structure 120 is used to absorb nitrogen in the air in the storage chamber. Since the volume fraction of nitrogen in the air is about 78%, when the absorption structure 120 absorbs part or all of the nitrogen in the air, the pressure in the storage chamber can be greatly reduced, thereby reducing oil leakage in the storage chamber.

[0065] When the absorption structure 120 is used to absorb nitrogen, the absorption structure 120 may be an active material that can react with nitrogen to generate a solid substance. The active material is in the form of a thin film of less than 10 microns. The active material may be selected or combined from metal lithium, sodium, potassium, barium, calcium, and strontium. It is understandable that in other embodiments of the present application, the absorption structure 120 may also be any other structure that can absorb nitrogen in the air, which is not limited here.

[0066] In yet another embodiment of the present application, the absorption structure 120 is used to absorb nitrogen and rare gases in the air in the storage chamber.

[0067] The following experiment is conducted to verify the before and after comparison of the atomization assembly 100 in the embodiment of the present application using the absorption structure 120. An absorption structure verification group and a non-absorption structure verification group are respectively set up, and two shells 110 are set up in the absorption structure verification group and the non-absorption structure verification group. When a large volume is left at night at the same time, it is observed at the same time during the day that the non-absorption structure verification group leaks while the absorption structure verification group does not leak. Then the two verification groups are puffed continuously for the same number of puffs at the same time, and both verification groups produce a suction curved liquid surface (that is, part of the smoke oil enters the ventilation channel, causing the smoke oil in the night storage chamber to drop), but within a short period of time after the suction is ended, the non-absorption structure verification group cannot suck back the suction curved liquid surface, while the absorption structure verification group can suck all the leaked smoke oil back into the night storage chamber.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
