[0019] The above explanation of main element symbols is combined with the drawings and specific technologies to make further detailed description of the reservoir. Specific implementation

[0020] In order to make the above-mentioned purposes, features and advantages of the reservoir more obvious and easy to understand, the specific technical solutions of the reservoir are described in detail below in combination with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the reservoir. However, the reservoir can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the reservoir, so the reservoir is not limited by the specific technical solutions disclosed below.

[0021] The terms "first", "second", "third", "fourth" in the specification are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0022] It should be noted that the up, down, left, right, front, back and other orientation words mentioned in the specification are based on the orientation in the drawings of the specification, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] The "limiting connection" in the present application includes clamping, hinging, etc. The "fixed connection" in the present application includes threaded connection, welding, bonding, vulcanization fixing, riveting, insert injection molding, interference fit, etc.

[0024] The present application will be further described below in conjunction with the drawings and specific technical solutions:

[0025] Figures 1 to 9 A technical solution of a liquid reservoir 100 is shown, which includes a body 10, a head 20, a suction tube 30 and a drying assembly 40. The body 10 has a containing cavity 11. The suction tube 30 is limitingly connected with the head 20, and at least part of the suction tube 30 is located in the containing cavity 11. The drying assembly 40 includes a blocking net 41 and a drying bag 42. In the radial direction of the liquid reservoir 100, the radial inner side of the blocking net 41 is fixedly connected with or abuts against the suction tube 30, and the radial outer side of the blocking net 41 abuts against or clearance fits with the wall forming the containing cavity 11. In the axial direction of the liquid reservoir 100, the drying bag 42 is located on one side of the blocking net 41, and the drying bag 42 is fixedly connected with or limitingly connected with the blocking net 41. In the present technical solution, the drying bag 42 is preferably but not limited to a molecular sieve bag, which can absorb moisture in the liquid refrigerant.

[0026] It should be noted that in some technical solutions, the blocking net 41 is in the form of a circular ring, and the blocking net 41 is annularly arranged on the outer periphery of the suction tube 30. In the radial direction of the liquid reservoir 100, the radial inner side of the blocking net 41 is fixedly connected with the suction tube 30, and the radial outer side of the blocking net 41 abuts against or clearance fits with the wall forming the containing cavity 11. In this way, the blocking net 41 can achieve radial limitation of the suction tube 30. The drying bag 42 is located on one side of the blocking net 41, and the drying bag 42 is fixedly connected with or limitingly connected with the blocking net 41. Compared with the prior art, the present technical solution uses a single layer of blocking net 41 to achieve limitation of the drying bag 42, which can save costs. In addition, the radial inner side of the blocking net 41 is fixedly connected with the suction tube 30, and the radial outer side of the blocking net 41 abuts against or clearance fits with the wall forming the containing cavity 11. In this way, the blocking net 41 can cooperate with the wall forming the containing cavity 11 to achieve radial limitation of the suction tube 30.

[0027] In combination with Figures 5 to 7As shown, the liquid accumulator 100 comprises a filter 50 having filter holes (not shown in the figure) communicating the pipe 31 of the suction tube 30 and the containing cavity 11, one end of the suction tube 30 being limitingly connected or fixedly connected with the head 20, one end of the suction tube 30 being limitingly connected or fixedly connected with the filter 50, along the axial direction of the liquid accumulator 100, one end of the filter 50 abutting against the barrier net 41, and one end of the filter 50 abutting against the bottom wall forming the containing cavity 11. It should be noted that the filter 50 communicates the pipe 31 of the suction tube 30 and the containing cavity 11 through the filter holes, which can play a filtering impurity effect, and the liquid refrigerant is input from the inlet portion 21 into the containing cavity 11, and the drying bag 42 can absorb the moisture contained in the liquid refrigerant. Further, one end of the suction tube 30 is limitingly connected with the head 20, and the other end of the suction tube 30 can make one end of the filter 50 abut against the wall forming the containing cavity 11, thereby limiting the action of the filter 50 in the axial direction. In the technical solution, the wall forming the containing cavity 11 is the bottom wall of the containing cavity 11.

[0028] For details, please refer to Figure 5 The liquid accumulator 100 further comprises a limiting member 43, the drying bag 42 is located radially outward of the suction tube 30, and the limiting member 43 can bind the drying bag 42 to the barrier net 41. In this way, the single-layer barrier net 41 cooperates with the limiting member 43 to achieve the limitation of the drying bag 42. On the one hand, it can reduce the production cost of the liquid accumulator 100; on the other hand, if the double-layer barrier net 41 structure is used, the flow resistance of the liquid refrigerant input from the inlet portion 21 into the containing cavity 11 will be increased, which is not conducive to the flow of the liquid refrigerant. The limiting member 43 in the technical solution is a cable tie. By using the structure design of the single-layer barrier net 41, the flow resistance of the liquid refrigerant caused by the barrier net 41 structure can be reduced, the flow of the liquid refrigerant can be facilitated, and the liquid refrigerant can quickly reach other nodes of the refrigeration system.

[0029] Further, the drying bag 42 is located on one side of the barrier net 42, and the filter 50 is located on the other side of the barrier net 41. In this way, it is beneficial for space arrangement. If the drying bag 42 is arranged on the same side of the filter 50, the axial dimension of the drying bag 42 is limited by the axial dimension of the filter 50, which affects the drying effect.

[0030] Specifically, part of the limiting member 43 is located on the side of the drying bag 42 away from the barrier net 41 and abuts against the drying bag 42, and part of the limiting member 43 is located away from the drying bag 42 relative to the barrier net 42 and abuts against the barrier net 41. In this way, the limiting member 43 can bind the drying bag 42 to the upper end of the barrier net 41, and the fixing effect of the drying bag 43 is good.

[0031] Specifically, the blocking net 41 has through holes 414, and the limiting members 43 pass through the through holes 414 to bind the drying bag 42 to the blocking net 41. In the technical solution, the number of the through holes 414 is multiple, each through hole 414 is arranged at intervals from each other, the limiting member 43 passes through at least two through holes 414, and the limiting member 43 can pass through the through holes 414 to bind the drying bag 42 to the blocking net, so that the fixing effect is good. In addition, in the description of the present application, the meaning of “multiple” is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited.

[0032] For details, please refer to Figure 6 In some technical solutions, the blocking net 41 has through holes 414, the drying bag 42 has a plug-in member 44, the plug-in member 44 has a large-diameter part 441 and a small-diameter part 442, at least part of the small-diameter part 442 is located in the through hole 414, the large-diameter part 441 is away from the drying bag 42 relative to the through hole 414, and the radial dimension of the large-diameter part 441 is greater than the radial dimension of the through hole 414. It should be noted that in this technical solution, the drying bag 42 can be fixed to the blocking net 41 by inserting the plug-in member 44 into the through hole 414, and this technical solution can also fix the drying bag 42 to the blocking net 41. In addition, this fixing method makes the drying bag 42 more convenient to assemble and disassemble. Specifically, the plug-in member 44 is made of a flexible material that can deform, and because the radial dimension of the large-diameter part 441 is greater than the radial dimension of the through hole 414, when the large-diameter part 441 passes through the through hole 414, at least part of the large-diameter part 441 abuts against the blocking net 41 to fix the drying bag 42 to the blocking net 41.

[0033] For details, please refer to Figure 9 Specifically, the blocking net 41 has a through avoiding hole 415, at least part of the liquid suction pipe 30 can pass through the avoiding hole 415, the blocking net 41 includes a main body part 411 and a limiting part 412, the main body part 411 is in a plate shape, and along the axial direction of the liquid reservoir 100, the limiting part 412 extends from the main body part 411 towards the direction of the head 20, and the limiting part 412 is fixedly connected with the liquid suction pipe 30. It should be noted that the main body part 411 and the limiting part 412 are an integral structure, the limiting part 412 extends from the edge of the wall forming the avoiding hole 415 towards the direction of the head 20, and the limiting part 412 is fixedly connected with at least part of the liquid suction pipe 30, so as to realize the radial limitation of the liquid suction pipe 30. Here, the fixed connection mode is preferably but not limited to riveting fixation.

[0034] In the description of the utility model, need understanding is, the term "upper", "lower", "front", "back", "left", "right", "axial", "radial", "circumferential" and so on indicate the orientation or positional relation is based on the orientation or positional relation shown in the drawing, only for the convenience of describing the present application and simplifying the description, and it is not indicated or implied that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0035] The baffle net 41 comprises an extension portion 413 extending from the radial outer periphery of the main body portion 411 in the direction away from the head 20 in the axial direction of the liquid reservoir 100, and the outer periphery of the extension portion 413 abuts or clearance fits with the wall forming the accommodation cavity 11. It should be noted that the extension portion 413 extends from the main body portion 411 in the direction away from the head 20, which can extend the limiting length of the extension portion 413 in the axial direction of the liquid reservoir 100, so that the extension portion 413 has a larger fitting area with the wall forming the accommodation cavity 11.

[0036] More specifically, the wall forming the accommodation cavity 11 comprises a first wall surface 113 and a second wall surface 114, one end of the filter 50 abuts the main body portion 411, one end of the filter 50 abuts the first wall surface 113, and the extension portion 413 abuts or clearance fits with the second wall surface 114.

[0037] The head 20 is fixedly connected with the body 10, and the fixed connection is preferably but not limited to welding. One end of the suction tube 30 is limitingly connected with the head 20, and one end of the suction tube 30 is limitingly connected with the filter 50. It should be noted that one end of the suction tube 30 is limitingly connected with the head 20, and one end of the suction tube 30 is limitingly connected with the filter 50, so that the suction tube 30 can abut one end of the filter 50 with the first wall surface 113. Thus, one end of the suction tube 30 is limitingly connected or fixedly connected with the head 20, and one end of the suction tube 30 abuts the filter 50 on the first wall surface 113. Since the baffle net 41 is fixedly connected with the suction tube 30, and the lower end of the baffle net 41 abuts the upper end of the filter 50, the axial position of the suction tube 30 and the filter 50 can be limited.

[0038] In combination Figures 5 to 7As shown, the receiving cavity 11 includes at least a first chamber 111 and a second chamber 112. The first chamber 111 and the second chamber 112 are arranged along the axial direction of the reservoir 100. The first chamber 111 is closer to the end cap 20 than the second chamber 112. The first chamber 111 is located on one side of the baffle 41, and the second chamber 112 is located on the other side of the baffle 41. The desiccant 42 is located in the first chamber 111, and the filter 50 is located in the second chamber 112. The baffle 41 has at least two through holes 414, which are spaced apart on the main body 411 and connect the first chamber 111 and the second chamber 112. It should be noted that the baffle 41 divides the receiving cavity 11 into at least the first chamber 111 and the second chamber 112. The first chamber 111 is used to place the desiccant 42, and the second chamber 112 is used to place the filter 50. The first chamber 111 and the second chamber 112 are connected to each other through the through holes 414. Understandably, the baffle 41 can radially restrict the suction tube 30 and the filter 50. Along the axial direction of the reservoir 100, the upper surface of the baffle 41 can cooperate with the limiting member to fix the drying package 42, and the lower surface of the baffle 41 can cooperate with the first wall surface 113 to axially restrict the filter 50. Specifically, the limiting member can fix the drying package 42 to the baffle 41 by passing through the through hole 414.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] Specifically, along the axial direction of the reservoir 100, the size of the first chamber 111 is larger than that of the second chamber 112. The desiccant 42 is located in the first chamber 111, the filter 50 is located in the second chamber 112, and there is a weld 12 between the end cap 20 and the body 10, with a gap between the desiccant 42 and the weld 12. It should be noted that the dimensions here refer to height. Because the height of the first chamber 111 is greater than that of the second chamber 112, more space can be reserved for the desiccant 42, thus relatively reducing the possibility of damage to the desiccant 42 caused by the heat generated during welding of the end cap 20 and the body 10 at the weld 12.

[0041] Combination Figure 1 , Figure 3 and Figure 5As shown, the head 20 includes an inlet portion 21 and an outlet portion 22, the inlet portion 21 and the outlet portion 22 are located on both sides of the head 20, the inlet portion 21 includes a first inlet 211, a second inlet 212 and a third inlet 213, the first inlet 211, the second inlet 212 and the third inlet 213 are all in communication with the containing cavity 11, the liquid suction pipe 30 has a pipe 31, the outlet portion 22 is in communication with the pipe 31. It should be noted that the first inlet 211 and the second inlet 212 are arranged along the axial direction of the liquid reservoir 100, the first inlet 211 and the second inlet 212 are both in communication with the containing cavity 11, based on Figure 5 As shown, the orientation relationship is the basis, the liquid suction pipe 30 is located between the second inlet 212 and the third inlet 213, the outlet portion 22 is located between the second inlet 212 and the third inlet 213, the first inlet 211 and the second inlet 212 are located on the left side, and the third inlet 213 is located on the right side. In addition, the plurality of inlets are used to input the liquid refrigerant, which improves the conveying efficiency.

[0042] In combination with Figures 5 to 7 As shown, the head 20 has a limiting cavity 23 and a cavity 24, the limiting cavity 23 is in communication with the outlet portion 22 and the pipe 31, at least part of the liquid suction pipe 30 is located in the limiting cavity 23, and the cavity 24 is in communication with the third inlet 213. It should be noted that at least part of the liquid suction pipe 30 is located in the limiting cavity 23, and the wall forming the limiting cavity 23 has a good limiting effect on the liquid suction pipe 30. The cavity 24 is recessed from the bottom wall of the head 20 towards the direction away from the blocking net 41, and the cavity 24 is in communication with the third inlet 213. In this way, on the one hand, the cost of the head 20 can be reduced, and on the other hand, the output size of the third inlet 213 can be increased, thereby improving the output efficiency.

[0043] It should be noted that the above technical solutions are only used to illustrate the present application and not to limit the technical solutions described in the present application.
