Description

Technical Field

[0001] This utility model relates to the field of fluid control technology, and in particular to a liquid reservoir. Background Technology

[0002] A refrigeration system includes a compressor, evaporator, condenser, throttling element, and reversing valve. It typically uses an electronic expansion valve as the throttling element and a receiver to store excess refrigerant.

[0003] Chinese utility model application 202121879301.8 discloses a liquid reservoir, including a cylindrical body open at one end with a cap at the opening, and a mesh frame assembly at the other end of the cylindrical body. A filter assembly is fixedly mounted on the mesh frame assembly. The cap has an outlet and an inlet, and both the outlet and inlet are detachably fitted with plugs. A pipeline assembly is provided between the filter assembly and the outlet. A drying package is bundled onto the pipeline assembly. The mesh frame assembly has multiple drainage holes. The filter part of the filter assembly extends into the mesh frame assembly. Liquid flowing into the cylindrical body through the inlet enters the mesh frame assembly through the drainage holes, then passes through the filter assembly and into the pipeline assembly, finally exiting through the outlet. The mesh frame assembly can prevent the drying package from sliding down and cover the filter assembly, but the mesh frame assembly needs to be separately installed with an interference fit to the cylindrical body, increasing the assembly process and product cost.

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0023] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0024] refer to Figures 1 to 7 As shown, this utility model provides a liquid storage device, including a cylindrical body 1 with one end open, and a cap 2 is provided at the opening of the cylindrical body 1. A filter assembly 4 is provided at the other end of the cylindrical body 1. An outlet 6 and an inlet 7 are provided on the cap 2. An outlet pipe 5 is provided between the filter assembly 4 and the outlet 6. The filter assembly 4 is fixedly sleeved outside the port of the outlet pipe 5. A drying bag 10 is tied to the outlet pipe 5.

[0025] The filter assembly 4 includes a cylindrical frame 402 with windows on its sidewalls, a first filter 401, and a partition 403 with snap-fit ​​fasteners. The partition 403 is sleeved with the liquid outlet pipe 5 and snap-fitted to the open end of the frame 402, sealing the open end of the frame 402 and leaving a channel for cooperation with the liquid outlet pipe 5. The first filter 401 is fixedly mounted around the frame. The inner wall of the frame and the outer periphery of the liquid outlet pipe 5 maintain a predetermined distance of 10mm to increase the refrigerant flow area. Even if the filter is partially blocked by impurities, it will not cause a significant flow resistance. Multiple protrusions 404 are provided at the bottom of the frame to prevent the liquid outlet pipe port from being blocked. The protrusions 404 are provided with mating parts 407 that guide the outer wall of the liquid outlet pipe 5 to prevent the end of the liquid outlet pipe from tilting. The open end of the frame 402 is provided with an outward flange, and the partition 403 is provided with an inward flange. The outward flange of the frame open end and the inward flange of the partition 403 are snap-fitted to prevent them from coming off. After assembly, when the filter assembly 4 abuts against the bottom of the cylinder 1, the liquid outlet pipe 5 prevents the filter assembly 4 from detaching. The partition plate 403 is interference-fitted with the liquid outlet pipe 5 for easy and integrated assembly. The filter assembly is first formed as a whole before being installed into the cylinder, simplifying the assembly process and reducing product costs.

[0026] The partition plate 403 is provided with multiple drainage holes 405. Liquid flowing into the cylinder from the inlet 7 passes through the drainage holes 405, the partition plate, and then through the first filter screen 401 before entering the outlet pipe. The first filter screen blocks the drainage holes, and finally the liquid is discharged from the outlet 6. The filter screen assembly, drying package, and outlet pipe are assembled as a whole before being installed into the cylinder, simplifying the assembly process and reducing product costs. The partition plate 403 is made of plastic injection molding, and the frame 402 is made of plastic and the first filter screen 401 injection molding. The partition plate 403 and the cylinder 1 are fitted with a clearance fit, and a second filter screen 406 is fixed to the partition plate 403 by injection molding. The second filter screen is a coarse mesh, which can initially filter impurities in the refrigerant.

[0027] The cap 2, filter assembly 4, drier pack 10, and liquid outlet pipe 5 can be assembled into a single unit first, and then installed into the cylinder 1, simplifying the assembly process. The drier pack 10 abuts against the upper surface of the partition 403. The drier pack 10 can absorb moisture from the refrigerant, and the partition can also prevent the drier pack from sliding further if it becomes loose. The cap 2 and the liquid outlet pipe 5 are interference-fitted for easy and secure assembly.

[0028] The cover 2 includes two parallel plug-in connectors 201 perpendicular to the axis of the cylinder 1 and a fixing hole 202. The connectors 201 are inserted into the opening of the system pipeline and fixed through the fixing hole.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
