[0002] An electronic atomization device is a device for atomizing a liquid medium into an aerosol, mainly including a liquid storage container for storing an atomization liquid and an atomization component assembled on the liquid storage container. In the natural environment, the air pressure inside the liquid storage container is easily affected by temperature, resulting in unstable air pressure inside the liquid storage container, causing the atomization liquid to be extruded out of the liquid storage container, resulting in leakage of the atomization liquid, and posing potential safety hazards during the storage, transportation, and use of the electronic atomization device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Embodiment: Please refer to Figures 1 to 7 , in this embodiment, a first aspect provides a liquid storage container 100, including: a container body, the container body is provided with a liquid storage space 110 and an opening communicating with the liquid storage space 110, and the opening is used for connecting and cooperating with an external component; Wherein, at least in the area facing the liquid storage space 110 on the inner wall of the container body, a flexible wall 200 is provided, and the flexible wall 200 has a pore structure to provide a pressure relief space for the fluid in the liquid storage space 110 when it expands due to heat.

[0024] In this embodiment, on the inner wall of the container body facing the liquid storage space 110, a flexible wall 200 with a pore structure is provided. When the fluid in the liquid storage space 110 expands due to heat, the pressure inside the liquid storage space 110 increases. However, through the deformation of the flexible wall 200 and the pore structure of the flexible wall 200, an elastic pressure relief space can be provided for the fluid, thereby reducing the pressure inside the liquid storage space 110. The pressure relief space can keep a certain pressure in the liquid storage space 110 at different temperatures, greatly reducing the risk of liquid leakage at the connection between the opening of the container body and the external component, and / or at other porous positions of the external component and the liquid storage container 100.

[0025] As an example, the fluid in the liquid storage space 110 includes liquid and / or gas. Specifically, the liquid in the liquid storage space 110 is an atomized liquid.

[0026] Further, the flexible wall 200 includes a first flexible layer 210 integrally formed on the inner wall of the container body, and the pore structure includes a plurality of first holes 211 spaced apart on the first flexible layer 210, and the first holes 211 constitute at least a part of the pressure relief space.

[0027] As Figure 1 and Figure 2 shown, it should be understood that the first flexible layer 210 can cover the entire inner wall of the container body, or only cover a part of the inner wall of the container body. If the first flexible layer 210 covers a part of the inner wall of the container body, then the first flexible layer 210 covers at least a part of the area of the inner wall of the container body where the liquid storage space 110 is provided. As an example, the area of the first flexible layer 210 covering the area of the inner wall of the container body where the liquid storage space 110 is provided can account for at least 20%, 30%, 35%, 40%, 50% or more of the area of the inner wall of the container body where the liquid storage space 110 is provided. Among them, the area of the first flexible layer 210 covering the inner wall of the container body should enable the first flexible layer 210 to have an area with enough space to set the pore structure, so as to ensure that the first flexible layer 210 can form enough pressure relief space.

[0028] A plurality of first holes 211 are provided in the region of the first flexible layer 210 covering the inner wall of the container body where the liquid storage space 110 is provided.

[0029] Specifically, as Figure 1 shown, as an example, the first flexible layer 210 covers the entire inner wall of the container body, and a number of first holes 211 are uniformly arranged in an array in the region of the first flexible layer 210 covering the inner wall of the container body where a partial liquid storage space 110 is provided. A number of first holes 211 are uniformly arranged in an array in the region of the first flexible layer 210 covering the inner wall of the container body where a partial liquid storage space 110 is provided. The first holes 211 and the flexible wall 200 both provide a pressure relief space for the fluid, which can better adjust the pressure in the liquid storage space 110 and effectively reduce the risk of liquid leakage from the liquid storage container 100.

[0030] It can be understood that the plurality of first holes 211 can also be irregularly distributed on the first flexible layer 210. For example, there are a dense area with a larger number of first holes 211 and a sparse area with a smaller number of first holes 211 on the first flexible layer 210. Among them, the temperature distributions in different regions of the container body may be different. The dense area and the sparse area can be correspondingly set according to the temperature distribution of the external environmental temperature acting on the container body. For example, the dense area is set corresponding to the high-temperature area on the container body, and the sparse area is set corresponding to the low-temperature area on the container body, so that the flexible wall 200 as a whole has a better pressure relief and buffering effect.

[0031] Furthermore, as Figures 1 to 2 shown, the first holes 211 penetrate through to the side of the first flexible layer 210 facing the liquid storage space 110, and the first holes 211 are capillary holes, so that when the fluid in the liquid storage space 110 expands due to heat, it enters the first holes 211.

[0032] In this embodiment, the first holes 211 are capillary holes. Capillary holes generally refer to fine holes with an inner diameter equal to or less than 1 mm. Capillary phenomena occur in the capillary holes for the liquid-like fluid in the liquid storage space 110. At normal temperature, the pressure inside the liquid storage space 110 is equivalent to the external atmospheric pressure, and the liquid-like fluid in the liquid storage space 110 does not wet the first holes 211, and the liquid-like fluid can be located outside the first holes 211. When the environmental temperature changes and the temperature of the liquid storage space 110 in the liquid storage container 100 rises, both the gaseous and liquid-like fluids in the liquid storage space 110 expand due to heat, the pressure in the liquid storage space 110 increases, and the liquid-like fluid enters the first holes 211. When the temperature of the liquid storage space 110 returns to normal temperature, the fluid that has entered the first holes 211 flows back into the liquid storage space 110.

[0033] As an example, the first hole 211 can be a through hole that penetrates the first flexible layer 210 in the thickness direction, or it can be a blind hole that only penetrates one side of the first flexible layer 210 facing the liquid storage space 110. The first hole 211 can be a tapered hole, a stepped hole, or a hemispherical hole with a gradually decreasing aperture in the thickness direction. Among them, the aperture of the first hole 211 on the side close to the liquid storage space 110 is larger than the aperture on the side far from the liquid storage space 110. Such a setting facilitates the integrally forming of the first flexible layer 210 with the first hole 211 on the inner wall of the container body, and also facilitates the fluid to enter and exit the first hole 211 due to temperature changes.

[0034] In this embodiment, as Figures 1 to 4 shown, the first hole 211 is a through hole that penetrates the first flexible layer 210 in the thickness direction, and the first hole 211 is a cylindrical capillary hole.

[0035] Furthermore, as Figures 1 to 4 shown, the aperture of the first hole 211 is 0.2 mm - 0.8 mm.

[0036] Furthermore, as Figures 1 to 4 shown, the first flexible layer 210 has a pressure relief area 210b and a sealing area 210a that are integrally connected. The pressure relief area 210b is arranged in the area on the inner wall of the container body facing the liquid storage space 110, and the sealing area 210a extends to the open end of the container body for sealing cooperation with external components. Among them, the first hole 211 is arranged on the pressure relief area 210b.

[0037] Between the open end of the traditional liquid storage container 100 and external components, it is sealed through a silicone part (such as an O-ring rubber seal). However, as Figure 1 and 2 shown, in some embodiments of the present invention, the first flexible layer 210 has a pressure relief area 210b and a sealing area 210a that are integrally connected. The sealing area 210a extends to the open end, making clever use of the ductility of the flexible wall 200, enabling the flexible wall 200 to achieve the same sealing effect as the silicone part. This sealing method has low requirements for process precision, simple process, convenient assembly, reduces the cost of sealing between the open end of the liquid storage container 100 and external components, and also reduces the risk of fluid overflowing from the liquid storage space 110.

[0038] Furthermore, as Figures 3 to 4 shown, the flexible wall 200 further includes a second flexible layer 220 arranged on one side of the first flexible layer 210 in the thickness direction to reduce the heat transfer of the flexible wall 200 from the container body to the liquid storage space 110 direction.

[0039] With such a setting, on the one hand, the second flexible layer 220 can undergo elastic deformation to provide an elastic pressure relief space for the fluid, so that a certain pressure can be maintained in the liquid storage space 110 at different temperatures. On the other hand, the second flexible layer 220 increases the thickness of the flexible wall 200, which can reduce the transfer of external heat into the liquid storage space 110 through the container body and reduce the influence of the external environmental temperature on the fluid in the liquid storage space 110. Both of the above aspects can reduce the risk of liquid leakage at the connection between the opening of the container body and the external component, or at other porous positions of the external component and the liquid storage container 100.

[0040] As an example, such as Figure 3 and Figure 4 shown, in some embodiments, the second flexible layer 220 is disposed on the side of the first flexible layer 210 facing the liquid storage space 110. The first flexible layer 210 and the second flexible layer 220 are sequentially stacked on the side wall inside the container body, forming a structure with a columnar cavity in the middle layer. The fluid that expands due to the increase in temperature in the liquid storage space 110 under the influence of the environmental temperature can squeeze towards the second flexible layer 220, causing the second flexible layer 220 to partially sink into the first holes 211 of the first flexible layer 210 to balance the pressure in the liquid storage space 110.

[0041] In other embodiments, the second flexible layer 220 can also be disposed between the first flexible layer 210 and the inner wall of the container body.

[0042] Furthermore, as Figures 1 to 4 shown, the first flexible layer 210 has a pressure relief area 210b and a sealing area 210a that are integrally connected. The pressure relief area 210b is disposed in the area on the inner wall of the container body facing the liquid storage space 110, and the sealing area 210a extends to the opening end. The first holes 211 are at least disposed in the pressure relief area 210b; The second flexible layer 220 is disposed on the side of the first flexible layer 210 facing the liquid storage space 110. The second flexible layer 220 at least partially covers the pressure relief area 210b and the sealing area 210a of the first flexible layer 210. The part of the second flexible layer 220 that at least covers the sealing area 210a is a non-porous layer for sealing contact with the external component.

[0043] As an example, such as Figure 3As shown, in one embodiment, the second flexible layer 220 is disposed on a surface of the first flexible layer 210 facing the liquid storage space 110. The second flexible layer 220 covers the entire surface of the first flexible layer 210, that is, the second flexible layer 220 covers the pressure relief area 210b and the sealing area 210a of the first flexible layer 210. The second flexible layer 220 is an overall non-porous layer. The first holes 211 are uniformly and spacedly disposed on the sealing area 210a and the pressure relief area 210b of the first flexible layer 210. Since the surface of the first flexible layer 210 is covered by the second flexible layer 220, the second flexible layer 220 can be in sealed contact with external components, and the setting of the first holes 211 in the sealing area 210a of the first flexible layer 210 does not affect the sealing performance between the opening of the liquid storage container 100 and external components.

[0044] In other embodiments, the first holes 211 may or may not be provided in the sealing area 210a of the first flexible layer 210, and neither will affect the sealing performance between the opening of the liquid storage container 100 and external components. In addition, those skilled in the art can, according to the actual situation of the product, cover the first flexible wall 200 and the second flexible wall 200 more on other positions of the liquid storage container 100, such as the inner wall of the ventilation pipe 120 on the side facing the liquid storage space 110.

[0045] Further, as Figure 4 shown, the second flexible layer 220 covers all the first holes 211 of the first flexible layer 210; In the pressure relief area 210b, the pore structure further includes a plurality of second holes 221 spacedly disposed on the second flexible layer 220, and at least some of the second holes 221 are in one-to-one correspondence and communication with at least some of the first holes 211; When the fluid in the liquid storage space 110 expands due to heat, it can sequentially enter the second holes 221 and the first holes 211 in the pressure relief area 210b.

[0046] As an example, as Figure 4 shown, in one embodiment, the second flexible layer 220 is disposed on a surface of the first flexible layer 210 facing the liquid storage space 110. The second flexible layer 220 covers the entire surface of the first flexible layer 210. The part of the second flexible layer 220 covering the sealing area 210a of the first flexible layer 210 is a non-porous layer for sealed contact with external components. The first holes 211 are uniformly and spacedly disposed on the sealing area 210a and the pressure relief area 210b of the first flexible layer 210. The part of the second flexible layer 220 covering the pressure relief area 210b of the first flexible layer 210 has a plurality of spaced second holes 221. The second holes 221 are in one-to-one correspondence and communication with the first holes 211. The first holes 211 and the second holes 221 communicate with each other to provide a pressure relief space for the fluid in the liquid storage space 110. When the fluid in the liquid storage space 110 expands due to heat, it can sequentially enter the second holes 221 and the first holes 211.

[0047] In practice, the inventors of the present application found that if a non-porous second flexible layer 220 is fully covered on the side of the first flexible layer 210 facing the liquid storage space 110, although it can play a certain role in pressure relief, it is required that the area occupied by the distribution area of the first holes 211 on the inner wall of the container body is relatively large, and the hole diameters should also be relatively large accordingly. In the embodiments of the present application, the fluid (mainly the liquid part) in the liquid storage space 110 can, in an external high-temperature environment, reduce thermal expansion by means of the heat insulation effect of the first flexible layer 210 and the second flexible layer 220, and at the same time, by providing second holes 221 on the second flexible layer 220, when there is thermal expansion, the fluid enters the first holes 211 through the second holes 221, which can ensure that the hole diameters of the first holes 211 can be made relatively large, so that the liquid in the liquid storage space 110 will not directly enter the first holes 211 at normal temperature due to the relatively large hole diameters of the first holes 211, thereby improving the overall pressure relief function of the flexible wall 200.

[0048] In this embodiment, the second holes 221 and the first holes 211 are through holes that penetrate the second flexible layer 220 and the first flexible layer 210 in the thickness direction, and both the second holes 221 and the first holes 211 are cylindrical. In other embodiments, the second holes 221 can also be tapered holes, stepped holes or hemispherical holes with gradually decreasing hole diameters in the thickness direction.

[0049] In some embodiments, the second holes 221 are capillary holes, and the hole diameters of the second holes 221 are smaller than the hole diameters of the first holes 211.

[0050] As Figure 4 shown, the second holes 221 are capillary holes. The liquid-like fluid in the liquid storage space 110 can generate capillary phenomena in the capillary holes, which are mainly manifested as that at normal temperature, the liquid-like fluid in the liquid storage space 110 does not wet the second holes 221, the liquid-like fluid in the liquid storage space 110 does not enter the second holes 221, the hole diameters of the second holes 221 are smaller than the hole diameters of the first holes 211, and regardless of whether the first holes 211 are set as capillary holes or non-capillary holes, the liquid-like fluid in the liquid storage space 110 will not enter the first holes 211 at normal temperature, which will not affect the formation of a pressure relief space in the liquid storage container 100. In this embodiment, the first holes 211 are set as capillary holes.

[0051] The hole diameters of the first holes 211 are larger than the hole diameters of the second holes 221, which also provides a larger pressure relief space for the fluid in the liquid storage space 110.

[0052] In some embodiments, the hole diameters of the second holes 221 are 5% - 30% of the hole diameters of the first holes 211. Specifically, the hole diameter range of the second holes 221 can be 0.01 mm to 0.8 mm.

[0053] As Figure 4As shown, in some embodiments, both the first hole 211 and the second hole 221 are capillary holes, and the aperture of the second hole 221 is set to 30% of the aperture of the first hole 211.

[0054] In some other embodiments, the second hole 221 is a capillary hole and the first hole 211 is a non-capillary hole. Among them, the second hole 221 is 0.01 mm to 0.8 mm, and the first hole 211 is 1 mm to 3 mm. At this time, the specific aperture size of the second hole 221 can be selected within the above range as 5% - 30% of the aperture of the first hole 211, or it can be other percentages.

[0055] In some embodiments, the hardness of the second flexible layer 220 is less than the hardness of the first flexible layer 210. Specifically, the hardness of the second flexible layer 220 is 10% - 40% of the hardness of the first flexible layer 210.

[0056] In some embodiments, the wall thickness of the second flexible layer 220 is less than the wall thickness of the first flexible layer 210. Specifically, the thickness of the second flexible layer 220 is 25% - 50% of the thickness of the first flexible layer 210.

[0057] In some other embodiments, the hardness of the second flexible layer 220 is less than the hardness of the first flexible layer 210, and the wall thickness of the second flexible layer 220 is less than the wall thickness of the first flexible layer 210.

[0058] With such a setting, the first flexible layer 210 can also play a role in supporting the second flexible layer 220. The ductility and elasticity of the second flexible layer 220 are stronger than those of the first flexible layer 210, further expanding the pressure relief space generated by the elastic deformation of the flexible wall 200 in the liquid storage space 110.

[0059] As an example, the Shore hardness of the first flexible layer 210 is 25 - 45 degrees, and the Shore hardness of the second flexible layer 220 is 5 - 20 degrees. At this time, within the respective specific hardness ranges of the first flexible layer 210 and the second flexible layer 220, a hardness value that satisfies the hardness of the second flexible layer 220 being 10% - 40% of the hardness of the first flexible layer 210 can be selected, or a value outside the above percentage range can also be selected.

[0060] The Shore hardness is used to characterize the hardness of elastic materials. The second flexible layer 220 is used to provide support for the first flexible layer 210. As Figure 3 shown, in one embodiment, when the ambient temperature rises, the fluid inside the liquid storage space 110 expands due to heat, the pressure inside the liquid storage space 110 increases. When the first flexible layer 210 and the second flexible layer 220 are subjected to the same pressure, the elastic deformation of the second flexible layer 220 will be greater than that of the first flexible layer 210, and the second flexible layer 220 will be recessed toward the first hole 211 of the first flexible layer 210.

[0061] In some embodiments, the wall thickness of the flexible wall 200 is 1 mm - 6 mm.

[0062] As an example, as Figure 1 and 2 shown, if only the first flexible layer 210 is integrally formed on the inner wall of the container body, the thickness of the first flexible layer 210 is 1 mm - 5 mm at this time, and the total wall thickness of the flexible wall 200 is 1 mm - 5 mm.

[0063] Such as Figure 3 and 4 shown, if the flexible wall 200 includes the first flexible layer 210 and the second flexible layer 220, the total wall thickness of the flexible wall 200 is 3 mm - 6 mm. Among them, the thickness of the first flexible layer 210 can be 2 mm - 4 mm, and the thickness of the second flexible layer 220 can be 0.5 mm - 2 mm. As an example, the thickness of the first flexible layer 210 is 2 mm, and the thickness of the second flexible layer 220 can be 1 mm, or the thickness of the first flexible layer 210 is 2.5 mm, and the thickness of the second flexible layer is 0.5 mm, 0.6 mm or 1 mm, etc. It should be noted that under the condition of meeting the above overall thickness, within the respective thickness ranges of the first flexible layer 210 and the second flexible layer 220, specific values that satisfy the thickness of the second flexible layer 220 being 25% - 50% of the thickness of the first flexible layer 210 can be selected, or other values not within the above percentage range can also be selected.

[0064] Compared with the liquid storage container 100 with an externally added elastic pressure relief device, the flexible wall 200 in the present invention has a thickness in the millimeter range, which can not only meet the function of fluid heat expansion and pressure relief inside the liquid storage space 110, but also make the liquid storage container 100 thinner, lighter and more portable, ensuring that there is enough liquid storage space 110 inside the liquid storage container 100.

[0065] Furthermore, the material of the container body is a thermoplastic plastic, and the material of the flexible wall 200 is a thermoplastic elastomer.
