[0002] In related technologies, to solve the problem of fixing the desiccant pack, a cylindrical structure and a mesh retainer are often used to secure it. However, the current method of using a cylindrical structure and a mesh retainer has limitations because the internal dimensions of the cylindrical structure are fixed. It can only be used for desiccant packs of a single size and is difficult to adapt to desiccant packs of different sizes, resulting in poor versatility. Summary of the Invention

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention.

[0028] The terms “first,” “second,” “third,” and “fourth” used in this specification are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0029] It should be noted that the directional terms such as up, down, left, right, front, and back mentioned in this specification are based on the orientation in the accompanying drawings and are only for the convenience of describing this application and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] Figures 1 to 10 This illustration depicts an embodiment of a liquid storage device 100. The liquid storage device 100 includes a limiting component 10 and a mating component 20. The mating component 20 has a limiting hole 211. The limiting component 10 includes a frame portion 11 and a limiting member 12. The limiting member 12 is fixedly connected to the frame portion 11, limitedly connected, or is an integral structure with it. The limiting member 12 includes a support portion 121 and at least two snap-fit ​​portions 122. The support portion 121 is cylindrical. In other embodiments, the support portion 121 may also be cuboid or other irregular shapes, as long as the support portion 121 can pass through the limiting hole 211. At least a portion of the support portion 121 is located between the frame portion 11 and the mating component 20. At least a portion of the support portion 121 engages with the wall forming the limiting hole 211 through a clearance fit. At least two snap-fit ​​portions 122 are arranged axially spaced along the support portion 121. The mating component 20 engages with one of the at least two snap-fit ​​portions 122, thus allowing the limiting hole 211 to adjust the axial distance between the frame portion 11 and the mating component 20 by engaging with different snap-fit ​​portions 122. At least one snap-fit ​​portion 122 is located on the side of the mating component 20 relatively away from the frame portion 11. It should be noted that in this embodiment, the liquid storage device 100 is a liquid reservoir. Since at least a portion of the support portion 121 engages with the wall forming the limiting hole 211 through a clearance fit, when adjusting the distance between the frame portion 11 and the mating component 20, the support portion 121 can pass through the limiting hole 211 without obstructing its passage.

[0032] Figures 11 to 15This illustration illustrates an embodiment of a gas-liquid separation device 200. The gas-liquid separation device 200 includes a limiting component 10 and a mating component 20. The gas-liquid separation device 200 has a liquid storage chamber 101. The limiting component 10 and the mating component 20 are located in the liquid storage chamber 101. The mating component 20 has a limiting hole 211. The limiting component 10 includes a dispersing cup 13 and a limiting member 12. The limiting member 12 is fixedly connected to the dispersing cup 13, limitedly connected, or is an integral structure. The limiting member 12 includes a supporting portion 121 and at least two engaging portions 122. At least a portion of the supporting portion 121 is clearance-fitted with the wall forming the limiting hole 211. The at least two engaging portions 122 are arranged at intervals along the axial direction of the supporting portion 121. The mating component 20 is limitedly fitted with one of the at least two engaging portions 122. At least one engaging portion 122 is located on the side of the mating component 20 that is relatively far away from the dispersing cup 13.

[0033] It should be noted that, in this embodiment, the gas-liquid separation device 200 is a gas-liquid separator. At least a portion of the support portion 121 is fitted with the wall gap forming the limiting hole 211. At least two snap-fit ​​portions 122 are arranged at intervals along the axial direction of the support portion 121. The mating component 20 is fitted with one of the at least two snap-fit ​​portions 122. At least one snap-fit ​​portion 122 is located on the side of the mating component 20 that is relatively far away from the liquid dispersing cup 13. In this way, the mating component 20 can adjust the distance between the liquid dispersing cup 13 and the mating component 20 by fitting with different snap-fit ​​portions 122.

[0034] In the description of this application, it should be understood that the terms "length", "width", "thickness", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] In related technologies, a cylindrical structure and a mesh retainer are often used to fix the drying element 30 to achieve the above purpose. However, since the internal space of the cylindrical structure is fixed, it can only be used for drying elements 30 of a single size, making it difficult to adapt to drying elements 30 of different sizes, resulting in poor versatility. The technical solution provided in this application has at least a portion of the support portion 121 located between the frame portion 11 and the mating component 20, at least a portion of the support portion 121 having a clearance fit with the wall forming the limiting hole 211, at least two locking portions 122 arranged axially spaced along the support portion 121, and the mating component 20 having a limiting fit with one of the at least two locking portions 122. At least one locking portion 122 is located on the side of the mating component 20 relatively away from the frame portion 11. In this way, the mating component 20 can adjust the distance between the frame portion 11 and the mating component 20 by limiting fit with different locking portions 122, thus adapting to drying elements 30 of different sizes.

[0036] In this technical solution, the number of snap-fit ​​parts 122 is multiple. In the description of this technical solution, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Specifically, in this application, each support part 121 corresponds to three snap-fit ​​parts 122.

[0037] Please refer to the following for details. Figure 5 When the mating component 20 engages with the snap-fit ​​portion 122 located away from the frame portion 11, at least a portion of the mating component 20 is located between two adjacent snap-fit ​​portions 122, at which point the two snap-fit ​​portions 122 restrict the mating component 20. Understandably, at this time, the mating component 20 is located at the upper end of the limiting component 10, and the distance between the mating component 20 and the frame portion 11 is the farthest.

[0038] When the mating component 20 engages with the locking portion 122 located in the middle, at least part of the mating component 20 is located between two adjacent locking portions 122, at which time the two locking portions 122 restrict the mating component 20.

[0039] When the mating member 20 engages with the snap-fit ​​portion 122 near the frame portion 11, at least one snap-fit ​​portion 122 is located at the end of the mating member 20 that is relatively far from the frame portion 11. At this time, the snap-fit ​​portion 122 engages with the frame portion 11 to restrict the mating member 20. Understandably, at this time, the mating member 20 is located at the lower end of the limiting member 10, and the distance between the mating member 20 and the frame portion 11 is the closest.

[0040] Please refer to the following for details. Figure 6In some embodiments, the snap-fit ​​portion 122 includes a first snap-fit ​​member 1221, which is located radially outside the support portion 121 and extends from the support portion 121 toward the frame portion 11. The first snap-fit ​​member 1221 includes a first end 12211 and a second end 12212. The first end 12211 is fixedly connected to the support portion 121, or is limited to it, or is an integral structure. The second end 12212 abuts against or is clearance-fitted with the mating component 20, and there is a gap between the second end 12212 and the support portion 121.

[0041] It should be noted that there is a gap between the second end 12212 of the first snap-fit ​​member 1221 and the support part 121, so that the first snap-fit ​​member 1221 can deform and pass through the limiting hole 211. After the first snap-fit ​​member 1221 passes through the limiting hole 211, the first snap-fit ​​member 1221 can abut or gap fit with the upper surface of the mating part 20 to restrict the mating part 20.

[0042] In some embodiments, the latching portion 122 includes a second latching member 1222. The second latching member 1222 and the first latching member 1221 are arranged radially spaced along the support portion 121. The second latching member 1222 is located radially outside the support portion 121 and extends from the support portion 121 toward the frame portion 11. The second latching member 1222 includes a third end 12221 and a fourth end 12222. The third end 12221 is fixedly connected to the support portion 121, or is limited to it, or is an integral structure. The fourth end 12222 abuts against or is clearance-fitted with the mating member 20, and there is a gap between the fourth end 12222 and the support portion 121.

[0043] It should be noted that there is a gap between the fourth end 12222 of the second latching member 1222 and the support portion 121, allowing the second latching member 1222 to deform. Since the second latching member 1222 and the first latching member 1221 are arranged radially at intervals along the support portion 121, when the first latching member 1221 and the second latching member 1222 pass through the limiting hole 211 and abut against the upper surface of the mating component 20, their arrangement can better restrict the mating component 20.

[0044] Please refer to the following for details. Figure 14In some embodiments, the snap-fit ​​portion 122 includes a first snap-fit ​​member 1221, which is located radially outside the support portion 121 and extends from the support portion 121 toward the dispensing cup 13. The first snap-fit ​​member 1221 includes a first end 12211 and a second end 12212. The first end 12211 is fixedly connected to the support portion 121, or is limited to it, or is an integral structure. The second end 12212 abuts against or is clearance-fitted with the mating component 20, and there is a gap between the second end 12212 and the support portion 121.

[0045] The latching part 122 includes a second latching member 1222. The second latching member 1222 and the first latching member 1221 are arranged radially spaced along the support part 121. The second latching member 1222 is located on the radially outer side of the support part 121 and extends from the support part 121 toward the liquid dispensing cup 13. The second latching member 1222 includes a third end 12221 and a fourth end 12222. The third end 12221 is fixedly connected to the support part 121, or is limited to it, or is an integral structure. The fourth end 12222 abuts against or is clearance-fitted with the mating part 20. There is a gap between the fourth end 12222 and the support part 121.

[0046] Please refer to the following for details. Figure 10 In some embodiments, the snap-fit ​​portion 122 includes a guide surface 1223, a first abutment surface 1224, and a second abutment surface 1225. Along the axial direction of the support portion 121, the second abutment surface 1225 is closer to the frame portion 11 than the first abutment surface 1224. Along the radial direction of the support portion 121, the second abutment surface 1225 is larger than the first abutment surface 1224. The guide surface 1223 is widened from the first abutment surface 1224 toward the second abutment surface 1225. The second abutment surface 1225 abuts or clearance-fits with the mating component 20. In this embodiment, the guide surface 1223 is frustoconical, and the snap-fit ​​portion 122 is a deformable plastic part, allowing the snap-fit ​​portion 122 to better pass through the limiting hole 211. Along the radial direction of the support portion 121, the size of the second abutting surface 1225 is larger than that of the first abutting surface 1224. When one of the locking portions 122 passes through the limiting hole 211, the second abutting surface 1225 of the locking portion 122 can play a certain role in preventing backflow.

[0047] In some embodiments, the snap-fit ​​portion 122 includes a guide surface 1223, a first abutting surface 1224, and a second abutting surface 1225. Along the axial direction of the support portion 121, the second abutting surface 1225 is closer to the dispensing cup 13 relative to the first abutting surface 1224. Along the radial direction of the support portion 121, the size of the second abutting surface 1225 is larger than that of the first abutting surface 1224. The guide surface 1223 is provided with an expanded diameter from the first abutting surface 1224 toward the second abutting surface 1225. The second abutting surface 1225 abuts or gap-fits with the mating component 20.

[0048] Combination Figures 1 to 10 As shown, in some embodiments, when there are two snap-fit ​​portions 122, when the mating member 20 is located between the two snap-fit ​​portions 122, the second abutting surface 1225 of the upper snap-fit ​​portion 122 abuts against the upper surface of the mating member 20, and the first abutting surface 1224 of the lower snap-fit ​​portion 122 abuts against the lower surface of the mating member 20. Thus, the two snap-fit ​​portions 122 can axially engage to axially restrict the mating member 20. When the mating member 20 is located between the lower snap-fit ​​portion 122 and the frame portion 11, the second abutting surface 1225 of the lower snap-fit ​​portion 122 abuts against the upper surface of the mating member 20, and the frame portion 11 abuts against the lower surface of the mating member 20.

[0049] It should be noted that when there are three or more snap-fit ​​parts 122, the mating part 20 can adjust the distance between the frame part 11 and the mating part 20 by engaging with different snap-fit ​​parts 122. Understandably, the more snap-fit ​​parts 122 there are, the greater the adjustable range of the distance between the mating part 20 and the frame part 11. In some embodiments, to allow the snap-fit ​​parts 122 to pass more smoothly through the limiting hole 211, a gap may exist between the guide surface 1223 and the support part 121, making deformation of the snap-fit ​​parts 122 easier.

[0050] Please refer to the following for details. Figure 10 In some embodiments, the snap-fit ​​portion 122 has a plurality of openings 1226 arranged in a ring, so that the snap-fit ​​portion 122 can pass through the limiting hole 211 more smoothly.

[0051] Combination Figures 3 to 7 As shown, the liquid storage device 100 includes a drying element 30. In this embodiment, the drying element 30 is a molecular sieve package. The frame portion 11 has a first receiving space 111. Along the axial direction of the liquid storage device 100, there is a second receiving space 112 between the frame portion 11 and the mating component 20. The opening of the first receiving space 111 communicates with the second receiving space 112. At least a portion of the drying element 30 is located in the first receiving space 111 and at least a portion of the drying element 30 is located in the second receiving space 112. One end of the drying element 30 abuts against the mating component 20, and the other end of the drying element 30 abuts against the bottom wall 115 forming the first receiving space 111. It should be noted that in this embodiment, part of the drying component 30 is located in the first receiving space 111, and another part of the drying component 30 is located in the second receiving space 112. The axial dimension of the first receiving space 111 is constant, while the axial dimension of the second receiving space 112 is adjustable. When the mating component 20 is engaged with the snap-fit ​​portion 122 at different positions, the second receiving space 112 changes accordingly to accommodate drying components 30 of different sizes.

[0052] In this embodiment, the number of limiting members 12 is at least two, and the at least two limiting members 12 are distributed at intervals along the outer periphery of the drying member 30. Specifically, the number of limiting members 12 is four, and the four limiting members 12 are arranged around the end of the frame portion 11 near the mating member 20. In this way, when the mating member 20 adjusts the distance between the frame portion 11 and the mating member 20 by limiting engagement with different snap-fit ​​portions 122, on the one hand, the multiple limiting members 12 arranged around the frame portion 11 can improve the stability of the adjustment process; on the other hand, the multiple limiting members 12 can play a certain limiting role on the drying member 30, and can prevent the drying member 30 from leaking out of the second receiving space 112.

[0053] Combination Figures 12 to 15 As shown, the gas-liquid separation device 200 includes a drying element 30, a mating component 20 having a first receiving space 111, and a second receiving space 112 between the liquid dispersing cup 13 and the mating component 20 along the axial direction of the gas-liquid separation device 200. The first receiving space 111 and the second receiving space 112 are in communication. At least a portion of the drying element 30 is located in the first receiving space 111 and at least a portion of the drying element 30 is located in the second receiving space 112. One end of the drying element 30 abuts against the liquid dispersing cup 13, and the other end of the drying element 30 abuts against the bottom wall 115 forming the first receiving space 111.

[0054] Combination Figures 1 to 10 As shown, the frame portion 11 includes a side wall 113, a top wall 114, and a bottom wall 115. The side wall 113 has a first through hole 1131, and the bottom wall 115 has a second through hole 1151. The liquid storage device 100 has a liquid storage cavity 101. The limiting component 10 and the mating component 20 are located in the liquid storage cavity 101. The opening of the side wall 113 communicates with the liquid storage cavity 101. The first through hole 1131 communicates with the first receiving space 111 and the liquid storage cavity 101, and the second through hole 1151 communicates with the first receiving space 111 and the liquid storage cavity 101. The support portion 121 extends from the top wall 114 toward the mating component 20. It should be noted that the side wall 113 has a first through hole 1131, which connects the first receiving space 111 and the liquid storage chamber 101, allowing the liquid refrigerant in the liquid storage chamber 101 to enter the first receiving space 111 and be dried by the drying element 30 located in the first receiving space 111, absorbing the moisture therein. The bottom wall 115 has a second through hole 1151, which connects the first receiving space 111 and the liquid storage chamber 101. Similarly, this allows the liquid refrigerant in the liquid storage chamber 101 to enter the first receiving space 111 and be dried by the drying element 30 located in the first receiving space 111, absorbing the moisture therein.

[0055] Combination Figures 11 to 15As shown, the mating component 20 includes a side wall 113, a top wall 114, and a bottom wall 115. The bottom wall 115 has a second through hole 1151. The liquid storage device 100 has a liquid storage cavity 101. The opening of the side wall 113 communicates with the liquid storage cavity 101. The second through hole 1151 communicates with the first accommodating space 111 and the liquid storage cavity 101. The support portion 121 extends from the dispersing cup 13 toward the mating component 20.

[0056] Combination Figure 6 and Figure 7 As shown, there are at least two first through holes 1131, which are arranged in a ring around the side wall 113 at intervals. There are also at least two second through holes 1151, which are arranged at intervals on the bottom wall 115. The bottom wall 115 includes at least two first grid members 1152, each located between two adjacent second through holes 1151. It should be noted that the at least two first through holes 1131 arranged in a ring around the side wall 113 at intervals allow the liquid refrigerant in the liquid storage chamber 101 to more easily enter the first receiving space 111. Similarly, the at least two second through holes 1151 arranged at intervals on the bottom wall 115 allow the liquid refrigerant in the first receiving space 111 to enter the liquid storage chamber 101, and vice versa. Furthermore, the arrangement of the first grid members 1152 enhances the strength of the bottom wall 115. In this embodiment, both the first through hole 1131 and the second through hole 1151 are elongated.

[0057] In some embodiments, the first through hole 1131 and the second through hole 1151 may also be circular holes, elliptical holes, waist-shaped holes or irregular hole structures, as long as the first through hole 1131 and the second through hole 1151 can connect the first accommodating space 111 and the liquid storage chamber 101.

[0058] Please refer to the following for details.
