Then, the upper cover and the lower cover of the cylinder body are stamped out by steel plates, and then copper inlet pipes are welded to the upper cover and the lower cover of the cylinder body. After installing the internal components, finally, the cylinder body, the upper cover, and the lower cover of the cylinder body are welded. However, the metal material causes the liquid storage device to be heavy and the transportation cost to be relatively high. Moreover, the metal cylinder body of the liquid storage device needs to be painted for anti-corrosion treatment, resulting in environmental pollution. Summary of the Invention

Detailed implementation manner

[0032] The object of the present invention is to provide a liquid storage cylinder body, a compressor assembly and a manufacturing method, which are used to achieve the effects of reducing the large weight of the liquid storage cylinder body, reducing the transportation cost, improving the production and installation efficiency, improving the installation strength, eliminating the painting and anti - corrosion process, and protecting the environment.

[0033] In order to make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0034] See Figures 1-10 , the present invention provides a liquid storage cylinder body 100 for a compressor assembly 200. The liquid storage cylinder body 100 includes an upper cover 110 of the cylinder body, a main liquid storage cylinder body 120 and a lower cover 130 of the cylinder body. The upper cover 110 of the cylinder body, the main liquid storage cylinder body 120 and the lower cover 130 of the cylinder body are made of plastic material; at least one of the upper cover 110 of the cylinder body and the lower cover 130 of the cylinder body is welded to the main liquid storage cylinder body 120.

[0035] In this embodiment, the liquid storage cylinder body 100 is more lightweight by being injection - molded with plastic material, which is convenient for transportation and clamping, and is easy to process. Moreover, the material cost of the plastic material is lower, and the manufacturing efficiency of the injection - molding process is higher, effectively reducing the manufacturing cost of the liquid storage cylinder body 100; the liquid storage cylinder body 100 made of plastic will not rust, and no additional anti - corrosion treatment is required on the outside, thus protecting the environment; at least one of the upper cover 110 of the cylinder body, the main liquid storage cylinder body 120 and the lower cover 130 of the cylinder body is disassembled and then welded. On the one hand, it can flexibly replace the combination of parts, is convenient for changing the size, and is also convenient for each part to be separately molded. It is also convenient to install the internal components of the liquid storage and then assemble and seal the liquid storage cylinder body 100.

[0036] It should be noted that the main liquid storage cylinder body 120 is the cylindrical part in the liquid storage cylinder body 100.

[0037] Preferably, there is no working condition of friction in the liquid storage cylinder body 100, so the requirement for wear resistance is not high, and the material selection is more extensive. However, it is necessary to have a certain strength, corrosion resistance, oxidation resistance, and high-temperature resistance. Therefore, the plastic materials used for the upper cover 110 of the cylinder body, the main liquid storage cylinder body 120, and the lower cover 130 of the cylinder body are glass fiber-reinforced nylon, carbon fiber composite material, PEEK (polyether ether ketone), or BMC (bulk molding compound), etc., so as to be lighter and have sufficient strength to withstand the refrigerant pressure and have corrosion resistance.

[0038] Preferably, between the upper cover 110 of the cylinder body and the main liquid storage cylinder body 120, or between the lower cover 130 of the cylinder body and the main liquid storage cylinder body 120, they are joined by hot plate welding or ultrasonic welding, which can improve the strength of the connection part, avoid generating vibration noise by using fasteners, etc., and can further improve the sealing performance through welding.

[0039] In a specific embodiment, the main liquid storage cylinder body 120 and the upper cover 110 of the cylinder body are of an integrally injection-molded structure, and the lower cover 130 of the cylinder body is welded to the main liquid storage cylinder body 120.

[0040] It should be noted that after the main liquid storage cylinder body 120 and the upper cover 110 of the cylinder body are injection-molded together, the upper cover 110 of the cylinder body does not need to be injection-molded separately, saving the number of injection molding and welding times, simplifying the assembly process of the liquid storage cylinder body 100, and improving production efficiency. And the edges of the main liquid storage cylinder body 120 and the upper cover 110 of the cylinder body coincide, which is also convenient for the two to be demolded together.

[0041] In a specific embodiment, the main liquid storage cylinder body 120 and the lower cover 130 of the cylinder body are of an integrally injection-molded structure, and the upper cover 110 of the cylinder body is welded to the main liquid storage cylinder body 120.

[0042] It should be noted that the combined injection molding of the main liquid storage cylinder body 120 and the lower cover 130 of the cylinder body can make the lower cover 130 of the cylinder body not need to be injection-molded separately, reducing the number of injection molding and welding times, also simplifying the assembly process of the liquid storage cylinder body 100, and improving production efficiency. And the edges of the main liquid storage cylinder body 120 and the lower cover 130 of the cylinder body coincide, which is also convenient for the two to be demolded together.

[0043] In a specific embodiment, the upper cover 110 of the cylinder body, the main liquid storage cylinder body 120, and the lower cover 130 of the cylinder body can all be injection-molded separately, and then the three are welded into one piece at a time, so as to facilitate the replacement of the components of the upper cover 110 of the cylinder body, the main liquid storage cylinder body 120, and the lower cover 130 of the cylinder body and simplify their respective molds.

[0044] See Figures 1-2 , Figures 4-5, in a specific embodiment, the liquid storage cylinder 100 further includes: an air outlet pipe insert 140, and the air outlet pipe insert 140 is embedded in the lower cover 130 of the cylinder; wherein, the air outlet pipe insert 140 is installed in the mold of the lower cover 130 of the cylinder, and by injecting the lower cover 130 of the cylinder, the air outlet pipe insert 140 is fitted with the lower cover 130 of the cylinder.

[0045] It should be noted that the air outlet pipe insert 140 is used to introduce the refrigerant of gas-liquid mixture into the liquid storage cylinder 100 to achieve gas-liquid separation; when the lower cover 130 of the cylinder is injection molded, the air outlet pipe insert 140 can be closely fitted with the lower cover 130 of the cylinder, avoiding the loosening of the connection or the leakage of gas or liquid caused by the vibration of the air outlet pipe insert 140, so as to safely and stably transport the refrigerant; the installation efficiency of the air outlet pipe insert 140 is effectively improved by the insert injection molding method.

[0046] For example, the air outlet pipe insert 140 includes an air outlet pipe sleeve, or the air outlet pipe insert 140 is a separate air outlet pipe, which is not limited here.

[0047] Preferably, the air outlet pipe insert 140 includes an air outlet pipe sleeve and an air outlet pipe. The air outlet pipe sleeve forms a pipe sleeve structure in the middle of the bottom of the lower cover 130 of the cylinder, which is used to increase the contact and fit area between the air outlet pipe and the lower cover 130 of the cylinder, so as to improve the installation strength of the air outlet pipe. When the air outlet pipe sleeve is pre-installed as an insert in the mold of the lower cover 130 of the cylinder, the air outlet pipe can also be pre-installed into the air outlet pipe sleeve in advance; the air outlet pipe can also be installed into the air outlet pipe sleeve after the air outlet pipe sleeve is fitted and formed with the lower cover 130 of the cylinder, which is not limited here. Further, the circumferential side of the air outlet pipe insert 140 has an annular groove, so that the lower cover 130 of the cylinder forms an annular protrusion that fits with the annular groove after injection molding, thereby preventing the air outlet pipe insert 140 from disengaging from the lower cover 130 of the cylinder along the axis.

[0048] The air inlet of the air outlet pipe extends into one end of the inner cavity of the liquid storage cylinder near the upper cover 110 of the cylinder. At this time, setting the air outlet pipe sleeve can avoid the inclination of the air outlet pipe and improve the installation stability of the air outlet pipe. Further, the part of the air outlet pipe that cooperates with the air outlet pipe sleeve has a diameter increasing part, so as to form a frustum-shaped support structure and further improve the stability of the air outlet pipe. Still further, the diameter increasing part has a plurality of protrusions arranged circumferentially. For example, 3, 4 or 6 protrusions are uniformly arranged axially on the diameter increasing part, so as to improve the clamping effect between the diameter increasing part and the air outlet pipe sleeve and prevent the air outlet pipe from loosening along the axis or laterally.

[0049] Optionally, when the air outlet pipe insert 140 is a separate air outlet pipe, the lower cover 130 of the cylinder body is a conical structure, and a vertical bending portion is formed at the middle position of the lower cover 130 of the cylinder body. Specifically, the vertical bending portion is located at the bottom of the conical structure to form a tubular structure, and the tubular structure can increase the contact area between its inner wall and the outer wall of the air outlet pipe insert 140, so that after the lower cover 130 of the cylinder body is injection-molded, it can be stably connected to the air outlet pipe insert 140.

[0050] Further, the air outlet pipe insert 140 is, for example, a copper pipe, but this is not limited herein.

[0051] See Figures 1-2 , Figure 6 , in a specific embodiment, the liquid storage cylinder body 100 further includes: an air inlet pipe insert 150, and the air inlet pipe insert 150 is embedded in the upper cover 110 of the cylinder body; wherein, the air inlet pipe insert 150 is installed in the mold of the upper cover 110 of the cylinder body, and by injection-molding the upper cover 110 of the cylinder body, the air inlet pipe insert 150 is fitted with the upper cover 110 of the cylinder body.

[0052] It should be noted that the air inlet pipe insert 150 is used to discharge the separated gaseous refrigerant; when the upper cover 110 of the cylinder body is injection-molded, the air inlet pipe insert 150 can be closely fitted with the upper cover 110 of the cylinder body, avoiding loosening of the connection or leakage of air, liquid or refrigerant caused by the vibration of the air inlet pipe insert 150, so as to discharge the refrigerant safely and stably; the installation efficiency of the air inlet pipe insert 150 is effectively improved by using the insert injection molding method.

[0053] Preferably, the upper cover 110 of the cylinder body is a conical structure to facilitate the diffusion of the refrigerant to the periphery of the inner cavity of the liquid storage device after entering. A vertical bending portion is formed at the top of the upper cover 110 of the cylinder body. Specifically, the vertical bending portion is located at the top of the conical structure to form a tubular structure, and the tubular structure can increase the contact area between its inner wall and the outer wall of the air inlet pipe insert 150, so that after the upper cover 110 of the cylinder body is injection-molded, it can be stably connected to the air inlet pipe insert 150.

[0054] Further, the air inlet pipe insert 150 is, for example, a copper pipe, but this is not limited herein.

[0055] See Figures 1-2 , Figure 7 , in a specific embodiment, the liquid storage cylinder body 100 further includes: a filter element 160, and the filter element 160 is clamped in the main liquid storage cylinder body 120, close to one end of the upper cover 110 of the cylinder body, or is clamped in the upper cover 110 of the cylinder body, close to one end of the main liquid storage cylinder body 120.

[0056] It should be noted that the part from below the filter to the lower cover 130 of the cylinder is used to accommodate the refrigerant of the liquid storage device, and the filter can filter the refrigerant entering through the inlet pipe insert 150. When the upper cover 110 of the cylinder and the main cylinder 120 of the liquid storage device are injection-molded separately, it is convenient to install the filter at one end of the main cylinder 120 of the liquid storage device close to the upper cover 110 of the cylinder or at one end of the upper cover 110 of the cylinder close to the main cylinder 120 of the liquid storage device.

[0057] In a specific embodiment, the liquid storage cylinder 100 further includes: a first socket part 171 and a second socket part 172; at least one of the upper cover 110 of the cylinder and the lower cover 130 of the cylinder is provided with the first socket part 171, and the main cylinder 120 of the liquid storage device is provided with at least one second socket part 172. After the first socket part 171 and the second socket part 172 are sleeved with each other, they are welded and connected.

[0058] It should be noted that the first socket part 171 and the second socket part 172 can be installed with limited positions. Before the upper cover 110 of the cylinder and the main cylinder 120 of the liquid storage device are welded, or before the main cylinder 120 of the liquid storage device and the lower cover 130 of the cylinder are welded, they play a role in radial and axial positioning, realizing accurate coaxial installation and improving the welding accuracy; after the first socket part 171 and the second socket part 172 are adjusted with each other, the sleeved part can increase the welding contact area and improve the welding strength.

[0059] Among them, the first socket part 171 and the second socket part 172 can be a stepped matching structure or a matching structure with at least one inclined surface to realize the lateral limiting function. For example, the first socket part 171 is arranged at the end of the main cylinder 120 of the liquid storage device, and the second socket part 172 is arranged at one end of the upper cover 110 of the cylinder or the lower cover 130 of the cylinder close to the main cylinder 120 of the liquid storage device. The first socket part 171 is an inner ring structure, and the second socket part 172 is an outer ring structure. The second socket part 172 is sleeved outside the first socket part 171 to realize the positioning installation of the upper cover 110 of the cylinder and the main cylinder 120 of the liquid storage device, or the positioning installation of the main cylinder 120 of the liquid storage device and the lower cover 130 of the cylinder.

[0060] See Figures 8-10 , in a specific embodiment, the liquid storage cylinder 100 further includes: a pipeline positioning insert 180. The pipeline positioning insert 180 is located inside the main cylinder 120 of the liquid storage device. The center of the pipeline positioning insert 180 has an avoidance hole for passing through the outlet pipe insert 140 to realize the positioning of the outlet pipe insert 140. The pipeline positioning insert 180 also has liquid passing holes surrounding the avoidance hole for passing through the liquid refrigerant. Among them, the number of the liquid passing holes can be 4, 5, 6, 8, etc., which is not limited here.

[0061] Preferably, the inner wall of the main liquid storage cylinder body 120 has a step for supporting the pipeline positioning insert 180 to realize the positioning and installation of the pipeline positioning insert 180. Specifically, the wall thickness of the main liquid storage cylinder body 120 above the step is smaller than that of the main liquid storage cylinder body 120 below the step, and the pipeline positioning insert 180 is clamped with the inner wall of the main liquid storage cylinder body 120 above the step to realize stable installation, thereby further ensuring the fixation of the air outlet pipe insert 140.

[0063] It should be noted that the clamp 220 can stably fix the liquid storage cylinder body 100 on the side of the compressor housing 210, and the relative installation positions of the compressor housing 210 and the liquid storage cylinder body 100 remain unchanged, which is convenient for the pipeline connection between the two and avoids pipeline loosening; the structure of the clamp 220 can realize the disassembly and assembly of the liquid storage cylinder body 100, which is convenient for maintaining and replacing the liquid storage device.
