[0023] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used to explain the present application, and should not be understood as a limitation of the present application.

[0024] Reference will be made to Figure 1 A liquid storage device 100 according to an embodiment of the present application is described below.

[0025] As Figure 1 shown, the liquid storage device 100 according to an embodiment of the present application comprises a box body 10 and a liquid inlet pipe 20.

[0026] The box body 10 defines a liquid storage space 11; a part of the liquid inlet pipe 20 extends into the liquid storage space 11 and communicates with the liquid storage space 11, the liquid inlet pipe 20 is adapted to communicate with a liquid source, and a pipe wall of the liquid inlet pipe 20 is formed with an air hole 21 penetrating through the pipe wall, the air hole 21 being located in the liquid storage space 11.

[0027] The box body 10 can define the liquid storage space 11, the liquid storage space 11 can store liquid, and the liquid can be but is not limited to water, oil, solution, etc., the liquid inlet pipe 20 is arranged in communication with the liquid storage space 11, and specifically, a part of the liquid inlet pipe 20 can extend into the liquid storage space 11 to make the liquid inlet pipe 20 communicate with the liquid storage space 11. As some embodiments of the present application, the material of the liquid inlet pipe 20 can be but is not limited to food-grade polypropylene, polyethylene, etc., which can ensure that the liquid is not contaminated.

[0028] The liquid inlet pipe 20 has opposite two ends, one end of which communicates with the liquid storage space 11, and the other end communicates with a liquid source, and the liquid in the liquid source can flow into the liquid storage space 11 through the liquid inlet pipe 20.

[0029] The pipe wall of the liquid inlet pipe 20 is formed with an air hole 21 penetrating through the pipe wall, the air hole 21 being located in the liquid storage space 11, the liquid in the liquid source can flow into the liquid storage space 11 through the liquid inlet pipe 20, and as the liquid in the liquid source flows into the liquid storage space 11 through the liquid inlet pipe 20, the gas in the liquid storage space 11 can be discharged through the air hole 21 and the liquid inlet pipe 20 to balance the internal and external air pressures of the liquid storage space 11, so that the liquid in the liquid source can flow smoothly into the liquid storage space 11.

[0030] It should be noted that by arranging the air hole 21 on the wall of the liquid inlet pipe 20 and locating the air hole 21 in the liquid storage space 11, the gas in the liquid storage space 11 can be directly discharged from the liquid storage space 11 through the air hole 21, thereby balancing the internal and external air pressure of the liquid storage space 11, allowing the liquid in the liquid source to be smoothly injected into the liquid storage space 11, and such arrangement can avoid arranging the exhaust pipe communicating with the outside, thereby reducing the risk of bacteria, dust and the like entering the liquid storage space 11, and being beneficial to guarantee the cleanliness of the liquid storage device 100, and also being able to reduce the maintenance cost of the liquid storage device 100.

[0031] Therefore, by arranging the air hole 21 in the wall of the liquid inlet pipe 20 and located in the liquid storage space 11, when liquid is injected through the liquid inlet pipe 20, the air in the liquid storage space 11 can be discharged through the air hole 21 in the wall to balance the air pressure, thereby reducing the risk of bacteria, dust and the like entering the liquid storage space 11, and being beneficial to guarantee the cleanliness of the liquid storage device 100.

[0032] In some embodiments of the present application, as shown in Figure 1 The box body 10 has a top wall 12 and a bottom wall 13, the distance between the air hole 21 and the top wall 12 is A, the distance between the air hole 21 and the bottom wall 13 is B, and the relationship A < B is satisfied.

[0033] The distance A between the air hole 21 and the top wall 12 and the distance B between the air hole 21 and the bottom wall 13 satisfy the relationship A < B, that is, the distance A between the air hole 21 and the top wall 12 is less than the distance B between the air hole 21 and the bottom wall 13, in other words, the air hole 21 is closer to the top wall 12 of the box body 10.

[0034] When the liquid enters the box body 10, the liquid will deposit at the bottom of the liquid storage space 11, and the air will gather at the top of the liquid storage space 11. By arranging the distance A between the air hole 21 and the top wall 12 to be less than the distance B between the air hole 21 and the bottom wall 13, the gathered air can quickly and smoothly pass through the air hole 21 into the liquid inlet pipe 20 and be discharged, which is beneficial to improve the smoothness of the liquid injection, and can reduce the probability of the air hole 21 being submerged by the liquid, thereby improving the use reliability of the liquid storage device 100.

[0035] In some embodiments of the present application, as shown in Figure 1 The relationship 15 ≤ B / A ≤ 20 is satisfied.

[0036] That is, the ratio of the distance B between the air hole 21 and the bottom wall 13 to the distance A between the air hole 21 and the top wall 12 is greater than or equal to 15 and less than or equal to 20, in other words, the distance B between the air hole 21 and the bottom wall 13 is any multiple of the distance A between the air hole 21 and the top wall 12 between 15 times and 20 times.

[0037] In this way, the position of the air hole 21 is reasonable, the probability of the air hole 21 being submerged by liquid is significantly reduced, the air in the liquid storage space 11 can be effectively ensured to pass through the air hole 21 into the liquid inlet pipe 20 and be discharged, so that the liquid inlet is smooth.

[0038] In some embodiments of the utility model, the air hole 21 is multiple, and the multiple air holes 21 are arranged around.

[0039] The number of air holes 21 can be two, three, four or the like, and as some embodiments of the application, the number of air holes 21 is four, and the four air holes 21 are arranged around the liquid inlet pipe 20.

[0040] In this way, the exhaust efficiency of the liquid storage device 100 can be improved, the liquid inlet is more smooth, and the risk of poor exhaust caused by the blockage of a certain air hole 21 can be reduced, which is beneficial to improve the use reliability of the liquid storage device 100.

[0041] In some embodiments of the utility model, the air hole 21 is multiple, and the multiple air holes 21 are arranged along the height direction (i.e. Figure 1 The Z direction shown in the figure) of the box body 10.

[0042] As some embodiments of the application, the number of air holes 21 is four, and the four air holes 21 are arranged along the height direction (i.e. Figure 1 The Z direction shown in the figure) of the box body 10.

[0043] By arranging the multiple air holes 21 along the height direction (i.e. Figure 1 The Z direction shown in the figure) of the box body 10, the exhaust efficiency of the liquid storage device 100 can be improved, and in this way, the liquid level in the liquid storage space 11 can be continuously and stably exhausted when the liquid level changes, the liquid inlet is more smooth, and in addition, the risk of poor exhaust caused by the blockage of a certain air hole 21 can be reduced, which is beneficial to improve the use reliability of the liquid storage device 100.

[0044] As some embodiments of the application, the number of air holes 21 is eight, and the four air holes 21 are arranged around the liquid inlet pipe 20 to form a group of air hole groups, and the two groups of air hole groups are arranged at intervals along the height direction (i.e. Figure 1 The Z direction shown in the figure) of the box body 10.

[0045] In this way, the exhaust efficiency of the liquid storage device 100 can be further improved, the liquid level in the liquid storage space 11 can be continuously and stably exhausted when the liquid level changes, the liquid inlet is more smooth, and in addition, the risk of poor exhaust of the liquid storage device 100 caused by the blockage of a certain air hole 21 can be reduced, which significantly improves the use reliability of the liquid storage device 100.

[0046] In some embodiments of the utility model, as shown inFigure 1 As shown, the air hole 21 is configured as a circular hole, the diameter of the air hole 21 is R1, the diameter of the liquid inlet pipe 20 is R2, and the relationship 0.05≤R1 / R2≤0.3 is satisfied.

[0047] As shown, the air hole 21 is configured as a circular hole, the diameter of the air hole 21 is R1, the diameter of the liquid inlet pipe 20 is R2, and the relationship 0.05≤R1 / R2≤0.3 is satisfied.

[0048] It should be noted that if the ratio of the diameter R1 of the air hole 21 to the diameter R2 of the liquid inlet pipe 20 is too small, the air hole 21 will be too small, which will cause the liquid storage device 100 to be difficult to exhaust, affecting the liquid inlet efficiency of the liquid storage device 100. If the ratio of the diameter R1 of the air hole 21 to the diameter R2 of the liquid inlet pipe 20 is too large, the liquid is easy to flow into the liquid storage space 11 through the air hole 21, affecting the smoothness of the exhaust. By satisfying the relationship 0.05≤R1 / R2≤0.3 between the diameter R1 of the air hole 21 and the diameter R2 of the liquid inlet pipe 20, the ratio of the diameter of the air hole 21 to the diameter of the liquid inlet pipe 20 can be reasonably set, which is beneficial to improve the rate and stability of liquid inlet.

During installation, the sealing member can be installed in the recessed portion, and then the liquid inlet pipe 20 is arranged in the mounting hole.

[0051] Such arrangement can form a seal between the liquid inlet pipe 20 and the box body 10, reduce the probability of liquid flowing out of the mounting hole, and reduce the risk of bacteria, dust and the like entering the liquid storage space 11 through the gap between the mounting hole and the liquid inlet pipe 20, which is beneficial to ensure the cleanliness of the liquid storage device 100.
