Description
Technical Field
[0001] This utility model relates to the field of liquid storage technology, specifically to a liquid storage connection component, a liquid storage device, and a compressor. Background Technology
[0002] Currently, the industry standard for processing rotary compressor receiver vent pipes (such as inlet and outlet pipes) involves flame welding. The vent pipe and the cylinder are fitted with a clearance fit, and brass welding wire is used as the solder. During welding, the cylinder and vent pipe are heated by a flame, and then the welding wire is inserted, melting and flowing into the gap between the vent pipe and the cylinder to form a seal. The clearance between the vent pipe and the cylinder is maintained by welding fixtures. However, the current technology has a drawback: relying primarily on fixtures to ensure the assembly clearance during flame welding in current assembly methods and welding processes can easily lead to problems such as clearance misalignment, uneven solder penetration, insufficient penetration on one side, excessively large clearance on the other, and weld porosity during mass production.

The cylindrical body has an opening, and the inner wall of the opening is provided with a step to form a first segment and a second segment, thereby forming a receiving cavity for accommodating the sleeved welded component. The second segment is further away from the outer end of the opening than the first segment, and the inner diameter of the first segment is larger than the inner diameter of the second segment. The outer diameter of the sleeved welded component is equal to the inner diameter of the first segment so that the outer side of the sleeved welded component can abut against the inner wall of the first segment and the sleeved welded component can be placed on the step. The sleeved welded component is used to sleeve the outer side of the vent pipe.

[0009] Optionally, when the sleeved welded component is placed on the step and the vent pipe is inserted into the sleeved welded component, the sleeved welded component and the vent pipe can be interference-fitted.

[0026] The purpose of this utility model is to provide a liquid reservoir connection assembly, a liquid reservoir and a compressor, which uses a sleeve constraint to ensure that the vent pipe does not misalign during welding with the cylinder.
[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the liquid reservoir connection assembly in its assembled state according to an embodiment of the present invention. Figure 1As shown, to achieve the above objectives, this utility model provides a liquid reservoir connection assembly, including a cylinder 3, a vent pipe 1, and a sleeved welded component 2. The cylinder 3 has an opening 30, and the inner wall of the opening 30 is provided with a step to form a first segment 301 and a second segment 302, thereby forming a receiving cavity for accommodating the sleeved welded component 2. That is, the first segment 301 is located at the outer end of the opening 30, and the second segment 302 is further away from the outer end of the opening than the first segment 301. The inner diameter of the first segment 301 is larger than the inner diameter of the second segment 302. The outer diameter of the sleeved welded component 2 is equal to the inner diameter of the first segment 301 so that the outer side of the sleeved welded component 2 can abut against the inner wall of the first segment 301 and the sleeved welded component 2 can be placed on the step. The sleeved welded component 2 is used to sleeve the outer side of the vent pipe 1.
[0028] When using this invention, the sleeved welding component 2 is first sleeved on the outside of the vent pipe 1, and then the sleeved welding component 2 is placed on the step. Alternatively, the sleeved welding component 2 is placed on the step first, and then the vent pipe 1 is inserted into the sleeved welding component 2. In this case, since the outer diameter of the sleeved welding component 2 is equal to the inner diameter of the first segment 301, the outer side of the sleeved welding component 2 can abut against the inner wall of the first segment 301, and the sleeved welding component 2 can be placed on the step, thereby constraining the vent pipe 1 and preventing the gap between the vent pipe 1 and the cylinder 3 from shifting. With this configuration, this invention utilizes the sleeve constraint to ensure that the vent pipe 1 does not shift during welding with the cylinder 3.
[0029] It should be noted that the shape of the sleeved welding component only needs to be able to abut against the inner wall of the first segment 301 and to be able to be placed on the step. In one exemplary embodiment, the sleeved welding component 2 is a cylindrical structure. In another exemplary embodiment, the sleeved welding component is a ring-shaped structure.
[0030] Furthermore, the inner diameter of the sleeved welded component 2 is smaller than the inner diameter of the second segment 302. In an exemplary embodiment, the difference between the inner diameter of the second segment 302 and the inner diameter of the sleeved welded component 2 is less than 0.4 mm. When the sleeved welded component is placed on the step and the vent pipe is inserted into the sleeved welded component, the sleeved welded component can be melted by a welding process and welded to the vent pipe and the cylinder body. For specific effects, please refer to... Figure 2 , Figure 2 This is an overall schematic diagram of the liquid reservoir connection assembly after welding is completed, according to an embodiment of the present invention. Figure 221 in the figure refers to the sleeved weldment after it has been melted by the welding process. Setting the inner diameter of the sleeved weldment 2 to be smaller than the inner diameter of the second segment 302 allows some of the melted solder to flow between the second segment 302 and the sleeved weldment 2. The difference between the inner diameter of the second segment 302 and the inner diameter of the sleeved weldment 2 is set to be less than 0.4 mm to ensure that too much molten solder flows in, thereby achieving a high-quality and strong weld.
[0031] It should be understood that the welding process is existing technology, and describing the technical solution of this utility model using existing technology conforms to the scope of utility model protection. The welding process includes flame welding or high-frequency welding. High-frequency welding refers to a welding method that uses high-frequency current flowing through the contact surface of the workpiece to generate resistance heat, and applies pressure (or no pressure) to form a connection between the metal parts of the workpiece. High-frequency welding differs from resistance welding. In high-frequency welding, the welding current only makes parallel contact with the workpiece surface; in resistance welding, the current flows perpendicular to the welding interface. Generally, the frequency of high-frequency welding is selected between 300 and 450 kHz; resistance welding uses 50 kHz industrial frequency current. Further details will not be elaborated here.
[0032] Preferably, when the sleeved welding component 2 is placed on the step and the vent pipe 1 is inserted into the sleeved welding component 2, the sleeved welding component 2 and the vent pipe 1 can be interference-fitted. Specifically, the connection between the two can be press-fitting.
[0033] This utility model also provides a liquid reservoir, including any of the liquid reservoir connecting assemblies described above. Because the liquid reservoir includes the liquid reservoir connecting assembly, the liquid reservoir can utilize a sleeve constraint to ensure that the vent pipe does not experience gap misalignment during welding to the cylinder.
[0034] Since the compressor provided by this utility model and the liquid receiver connection assembly described above belong to the same utility model concept, the compressor provided by this utility model has all the advantages of the liquid receiver connection assembly described above. Therefore, the beneficial effects of the compressor provided by this utility model will not be described in detail here.
[0035] This utility model also provides a compressor including the liquid receiver. Because the compressor includes the liquid receiver, the compressor can utilize a sleeve constraint to ensure that no gap misalignment occurs when the vent pipe is welded to the cylinder.
[0036] Since the compressor provided by this utility model and the liquid receiver connection assembly described above belong to the same utility model concept, the compressor provided by this utility model has all the advantages of the liquid receiver connection assembly described above. Therefore, the beneficial effects of the compressor provided by this utility model will not be described in detail here.

Also, the word “or” should be understood to have the definition of logical “or” rather than logical “exclusive OR”, unless the context clearly indicates otherwise. Furthermore, implementation of embodiments of the invention may include performing selected tasks manually, automatically, or in combination.
