It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Examples:

referring to fig. 1 to 7, in a first aspect of the present embodiment, a liquid storage container 100 is provided, which includes: the container body is provided with a liquid storage space 110 and an opening communicated with the liquid storage space 110, and the opening is used for being connected and matched with an external part;

Wherein, the inner wall of the container body is provided with a flexible wall 200 at least towards the area of the liquid storage space 110, and the flexible wall 200 has a pore structure to provide a pressure relief space for the fluid of the liquid storage space 110 when the fluid expands due to heating.

In this embodiment, the inner wall of the container body facing the liquid storage space 110 is provided with a flexible wall 200 having a pore structure, when the fluid in the liquid storage space 110 is expanded by heating, the pressure in the liquid storage space 110 increases, and an elastic pressure release space can be provided for the fluid through the deformation of the flexible wall 200 and the pore structure of the flexible wall 200, so that the pressure in the liquid storage space 110 decreases, the pressure release space can keep a certain pressure in the liquid storage space 110 at different temperatures, and the risk of leakage between the opening of the container body and the connecting part of the external part and/or between the external part and other positions of the liquid storage container 100 having pores is greatly reduced.

As shown in fig. 1 and 2, it should be understood that the first flexible layer 210 may cover the entire inner wall of the container body or may cover only a partial inner wall of the container body. If the first flexible layer 210 covers a partial inner wall of the container body, the first flexible layer 210 covers at least a portion of the area of the inner wall of the container body where the liquid storage space 110 is provided, and as an example, the area of the first flexible layer 210 covering the inner wall of the container body where the liquid storage space 110 is provided may occupy 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, wherein the area of the first flexible layer 210 covering the inner wall of the container body should be such that the first flexible layer 210 has an area where the pore structure is sufficiently provided, thereby ensuring that the first flexible layer 210 can form a sufficient pressure relief space.

The plurality of first holes 211 are provided in the first flexible layer 210 in a region where the liquid storage space 110 is provided, which is covered on the inner wall of the container body.

Specifically, as shown in fig. 1, as an example, the first flexible layer 210 covers the entire inner wall of the container body, and the plurality of first holes 211 are uniformly arranged in an array on the inner wall of the container body, which covers the area of the first flexible layer 210 where a part of the liquid storage space 110 is provided. The even array of a plurality of first holes 211 sets up the region that is equipped with partial stock solution space 110 on the cover container body inner wall of first flexible layer 210, and first hole 211 and flexible wall 200 all provide the pressure release space for the fluid, can adjust the pressure in the stock solution space 110 better, effectively reduce the risk of stock solution container 100 weeping.

Further, as shown in fig. 1-2, the first hole 211 penetrates through the first flexible layer 210 to the surface facing the liquid storage space 110, and the first hole 211 is a capillary hole, so that the fluid in the liquid storage space 110 enters the first hole 211 when being heated and expanded.

In this embodiment, the first holes 211 are capillary holes, and the capillary holes are usually holes with an inner diameter equal to or smaller than 1mm, and the liquid fluid in the liquid storage space 110 generates capillary phenomenon in the capillary holes. At normal temperature, the pressure inside the liquid storage space 110 is equal to the external atmospheric pressure, the liquid fluid in the liquid storage space 110 does not infiltrate the first hole 211, and the liquid fluid can be located outside the first hole 211.

As an example, the first hole 211 may be a through hole penetrating the first flexible layer 210 in the thickness direction, or may be a blind hole penetrating only one surface of the first flexible layer 210 facing the liquid storage space 110. The first hole 211 may be a tapered hole, a stepped hole or a hemispherical hole with gradually reduced hole diameter in the thickness direction, wherein the hole diameter of the side of the first hole 211 close to the liquid storage space 110 is larger than the hole diameter of the side far away from the liquid storage space 110, so that the first flexible layer 210 with the first hole 211 is formed on the inner wall of the container body in an integrated manner, and meanwhile, fluid is convenient to enter and exit the first hole 211 due to temperature change.

In the present embodiment, as shown in fig. 1 to 4, the first hole 211 is a through hole penetrating the first flexible layer 210 in the thickness direction, and the first hole 211 is a cylindrical capillary hole.

Further, as shown in fig. 1 to 4, the aperture of the first hole 211 is 0.2mm to 0.8mm.

The open end of the conventional liquid storage container 100 is sealed with the external component by a silicone part (such as an O-ring), but as shown in fig. 1 and 2, in some embodiments of the present utility model, the first flexible layer 210 has a pressure relief area 210b and a sealing area 210a integrally connected, and the sealing area 210a extends to the open end, so that the ductility of the flexible wall 200 is smartly utilized, and the flexible wall 200 can have the same sealing effect as the silicone part.

Further, as shown in fig. 3 to 4, the flexible wall 200 further includes a second flexible layer 220 disposed on one side of the first flexible layer 210 along the thickness direction, so as to reduce heat transfer of the flexible wall 200 from the container body to the liquid storage space 110.

So set up, on the one hand, the second flexible layer 220 can produce elastic deformation and provide elastic pressure release space for fluid to make the internal pressure that keeps certain under different temperatures of stock solution space 110, on the other hand, the second flexible layer 220 has increased the thickness of flexible wall 200, can reduce outside heat and pass through the container body and transmit in the stock solution space 110, reduce the influence of external environment temperature to the fluid in the stock solution space 110, the junction of opening and external part of container body, or the risk that the liquid leakage takes place in the other positions that have the hole of external part and stock solution container 100 can both be reduced to the above-mentioned two aspects.

As an example, as shown in fig. 3 and 4, in some embodiments, the second flexible layer 220 is disposed on a side of the first flexible layer 210 facing the liquid storage space 110, and the first flexible layer 210 and the second flexible layer 220 are sequentially stacked on a sidewall in the container body, so that a structure in which an intermediate layer has a columnar cavity is formed, and fluid that expands due to a temperature rise in the liquid storage space 110 caused by an influence of an ambient temperature can be pressed against the second flexible layer 220, so that the second flexible layer 220 is partially recessed into the first hole 211 of the first flexible layer 210, and the pressure in the liquid storage space 110 is balanced.

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

As an example, as shown in fig. 3, in an 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 release region 210b and the sealing region 210a of the first flexible layer 210, the second flexible layer 220 is a non-porous layer, and the first holes 211 are uniformly disposed on the sealing region 210a and the pressure release region 210b of the first flexible layer 210 at intervals. Since the surface of the first flexible layer 210 covers the second flexible layer 220, the second flexible layer 220 can be in sealing contact with the external part, and the sealing area 210a of the first flexible layer 210 is provided with the first hole 211, the sealing property between the opening of the liquid storage container 100 and the external part is not affected.

In other embodiments, the sealing region 210a of the first flexible layer 210 may be provided with the first hole 211, or may not be provided with the first hole 211, which does not affect the tightness between the opening of the liquid storage container 100 and the external component. In addition, the person skilled in the art can 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 breather pipe 120 facing the side of the liquid storage space 110, according to the actual situation of the product.

Further, as shown in fig. 4, the second flexible layers 220 each cover the first hole 211 of the first flexible layer 210;

In the pressure relief area 210b, the pore structure further includes a plurality of second holes 221 disposed on the second flexible layer 220 at intervals, at least part of the second holes 221 are in one-to-one correspondence with at least part of the first holes 211;

The fluid in the fluid storage space 110 may sequentially enter the second hole 221 and the first hole 211 in the pressure release region 210b when being expanded by heat.

As an example, as shown in fig. 4, in an 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 is covered on the entire surface of the first flexible layer 210, a portion of the second flexible layer 220, which is covered on the sealing area 210a of the first flexible layer 210, is a non-porous layer for sealing contact with an external component, the first holes 211 are uniformly disposed on the sealing area 210a and the pressure release area 210b of the first flexible layer 210 at intervals, a portion of the second flexible layer 220, which is covered on the pressure release area 210b of the first flexible layer 210, has a plurality of second holes 221 disposed at intervals, the second holes 221 are in one-to-one correspondence with the first holes 211, and the first holes 211 and the second holes 221 are in communication to provide the liquid storage space for fluid in the liquid storage space 110 together, and when the fluid in the liquid storage space 110 is expanded by heating, the fluid can sequentially enter the second holes 221 and the first holes 211.

The present inventors have found that, in practice, if the second flexible layer 220 without pores is covered on the side of the first flexible layer 210 facing the liquid storage space 110, the first flexible layer can perform a certain pressure relief function, but the area where the first holes 211 are distributed is required to occupy a larger area on the inner wall of the container body, and the pore size is also correspondingly larger. In the embodiment of the application, the fluid (mainly the liquid portion) in the liquid storage space 110 can be in an external high-temperature environment, so that the thermal expansion can be reduced by means of the heat insulation effect of the first flexible layer 210 and the second flexible layer 220, meanwhile, the second hole 221 is arranged on the second flexible layer 220, and when in thermal expansion, the fluid enters the first hole 211 through the second hole 221, so that the aperture of the first hole 211 can be relatively larger, the liquid in the liquid storage space 110 can not directly enter the first hole 211 at normal temperature due to the larger aperture of the first hole 211, and the integral pressure relief function of the flexible wall 200 is improved.

In the present embodiment, the second hole 221 and the first hole 211 are through holes penetrating the second flexible layer 220 and the first flexible layer 210 in the thickness direction, and the second hole 221 and the first hole 211 are each cylindrical. In other embodiments, the second hole 221 may be a tapered hole, a stepped hole, or a hemispherical hole having a gradually decreasing hole diameter in the thickness direction.

In some embodiments, the second holes 221 are capillary holes, and the second holes 221 have a smaller pore size than the first holes 211.

As shown in fig. 4, the second hole 221 is a capillary hole, the liquid fluid in the liquid storage space 110 can generate a capillary phenomenon in the capillary hole, which is mainly represented by that the liquid fluid in the liquid storage space 110 does not infiltrate the second hole 221 at normal temperature, the liquid fluid in the liquid storage space 110 does not enter the second hole 221, the aperture of the second hole 221 is smaller than that of the first hole 211, no matter the first hole 211 is set as a capillary hole or a non-capillary hole, the liquid fluid in the liquid storage space 110 does not enter the first hole 211 at normal temperature, and the pressure release space of the liquid storage container 100 is not affected, in this embodiment, the first hole 211 is set as a capillary hole.

The first hole 211 has a larger aperture than the second hole 221 and also provides a larger pressure relief space for the fluid in the reservoir space 110.

In some embodiments, the aperture of the second hole 221 is 5% -30% of the aperture of the first hole 211. Specifically, the aperture range of the second hole 221 may be 0.01mm to 0.8mm.

In some embodiments, as shown in fig. 4, the first holes 211 and the second holes 221 are capillary holes, and the aperture of the second holes 221 is set to 30% of the aperture of the first holes 211.

In other embodiments, the second hole 221 is a capillary hole, the first hole 211 is a non-capillary hole, wherein the second hole 221 is 0.01mm to 0.8mm, and the first hole 211 is 1mm to 3mm, and at this time, the specific pore size of the second hole 221 may be selected to be 5% -30% of the pore size of the first hole 211 in the above range, or may be other percentages.

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.

In some embodiments, the wall thickness of the second flexible layer 220 is less than the wall thickness of the first flexible layer 210. The thickness of the particular second flexible layer 220 is 25% -50% of the thickness of the first flexible layer 210.

In 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.

So set up, first flexible layer 210 can also play the effect of supporting second flexible layer 220, and second flexible layer 220's ductility and elasticity are stronger than first flexible layer 210, have further enlarged the pressure release space that flexible wall 200 can elastically deform and produce in the liquid storage space 110.

As an example, the first flexible layer 210 has a durometer of 25-45 degrees and the second flexible layer 220 has a durometer of 5-20 degrees. At this time, in the specific hardness ranges of the first flexible layer 210 and the second flexible layer 220, the hardness value satisfying that the hardness of the second flexible layer 220 is 10% to 40% of the hardness of the first flexible layer 210 may be selected, or the value not within the above percentage range may be selected.

Du's hardness is used to characterize the hardness of the elastic material, and the second flexible layer 220 is used to provide support for the first flexible layer 210. In one embodiment, as shown in FIG. 3, when the ambient temperature increases, the fluid within the reservoir space 110 expands due to heat, the pressure within the reservoir space 110 increases, the elastic deformation of the second flexible layer 220 is greater than that of the first flexible layer 210 when the first flexible layer 210 and the second flexible layer 220 are subjected to the same pressure, and the second flexible layer 220 is recessed toward the first aperture 211 of the first flexible layer 210.

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

As an example, as shown in fig. 1 and 2, 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 1mm to 5mm, and the total wall thickness of the flexible wall 200 is 1mm to 5mm.

As shown in fig. 3 and 4, 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 3mm to 6mm, wherein the thickness of the first flexible layer 210 may be 2mm to 4mm, the thickness of the second flexible layer 220 may be 0.5mm to 2mm, and as an example, the thickness of the first flexible layer 210 may be 2mm, the thickness of the second flexible layer 220 may be 1mm, or the thickness of the first flexible layer 210 may be 2.5mm, the thickness of the second flexible layer may be 0.5mm, 0.6mm, 1mm, or the like. In the case where the total thickness is satisfied, a specific value satisfying the thickness of the second flexible layer 220 being 25% to 50% of the thickness of the first flexible layer 210 may be selected within the respective thickness ranges of the first flexible layer 210 and the second flexible layer 220, or other values not within the above percentage ranges may be selected.
