Technical Field
[0001] This utility model relates to the field of compressor technology, specifically to a dual-channel compressor. Background Technology
[0002] In recent years, with industrial development and the popularization of new energy vehicles, the usage of car refrigerators has been increasing year by year. Car refrigerators all require compressors for refrigeration. Existing compression devices usually adopt a direct connection method, that is, the high-pressure gas output by the compressor directly enters the copper pipe after passing through the flow channel. However, due to the working characteristics of reciprocating compressors, obvious pulse and airflow noise are easily generated when working at high pressure, which affects the stability of the system and the comfort of use. Utility Model Content
[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a rationally designed dual-channel compressor that can solve the aforementioned problems.

An outer cover is installed on the front side of the compression shell. A valve plate is provided between the compression shell and the outer cover. A piston hole for piston action to compress gas is opened in the compression shell. An outlet hole for high-pressure gas discharge is provided on the valve plate. An outlet valve plate is provided on the outlet hole. An outlet chamber is provided inside the outer cover. The outlet valve plate faces the outlet chamber. High-pressure gas holes are opened on both sides of the valve plate. The high-pressure gas holes are all connected to the outlet chamber. Two sets of flow channels are opened inside the compression shell. The two high-pressure gas holes are respectively connected to the two sets of flow channels. Both sets of flow channels are connected to the exhaust holes for gas discharge.
[0005] Preferably, one set of the flow channels is a buffer chamber one opened on the compression housing, which is located on the side of the exhaust port, and a venting groove is opened on the surface of the compression housing between the buffer chamber one and the exhaust port; the other set of flow channels includes a buffer chamber two and a buffer chamber three opened on the compression housing, a high-pressure air hole far away from the exhaust port is connected to the buffer chamber three, the buffer chamber two is opened between the buffer chamber three and the exhaust port, and venting grooves for gas flow are opened between the buffer chamber three and the buffer chamber two, and between the buffer chamber two and the exhaust port.
[0006] Preferably, the root of the exhaust port is threaded, and the valve plate and the outer cover are provided with holes opposite to the exhaust port. The outer cover is installed on the outside of the valve plate by screws. One screw is connected to the threaded connection through the aforementioned hole. A venting ring is pressed inside the screw. A high-pressure copper pipe for conveying high-pressure gas is connected to the venting ring. A venting hole is provided in the venting ring that connects the inside and outside. The venting hole is connected to the high-pressure copper pipe.
[0007] Preferably, the valve plate is further provided with an air inlet hole connected to the piston hole, and an air inlet valve plate is provided inside the air inlet hole.
[0008] The beneficial effects of this utility model after adopting the above structure are: This application provides two sets of buffer chambers inside the compressor housing and an outlet chamber inside the outer cover.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] See Figures 1-4As shown, it includes an outer shell 1, inside which is a compression shell 2 for gas compression, and a motor connected to the rear for driving operation. An outer cover 3 is installed on the front side of the compression shell 2. A valve plate 5 is provided between the compression shell 2 and the outer cover 3. A piston hole 9 is opened in the compression shell 2 for piston action to compress gas. An outlet hole 13 for high-pressure gas discharge is provided on the valve plate 5. An outlet valve plate 8 is provided on the outlet hole 13. An outlet chamber 14 is provided in the outer cover 3. The outlet valve plate 8 is directly opposite the outlet chamber 14. High-pressure air holes 6 are opened on both sides of the valve plate 5. The high-pressure air holes 6 are connected to the outlet chamber 14. Two sets of flow channels are opened in the compression shell 2. The two high-pressure air holes 6 are connected to the two sets of flow channels respectively. Both sets of flow channels are connected to the exhaust hole 15 for gas discharge. One set of flow channels is a buffer chamber 10 opened on the compression housing 2, which is located on the side of the exhaust port 15. A venting groove 16 is opened on the surface of the compression housing 2 between the buffer chamber 10 and the exhaust port 15. The other set of flow channels includes a second buffer chamber 11 and a third buffer chamber 12 opened on the compression housing 2. A high-pressure air hole 6 far away from the exhaust port 15 is connected to the third buffer chamber 12. The second buffer chamber 11 is opened between the third buffer chamber 12 and the exhaust port 15. Venting grooves 16 for gas flow are opened between the third buffer chamber 12 and the second buffer chamber 11, and between the second buffer chamber 11 and the exhaust port 15.
[0013] After the gas is compressed in the piston hole 9, the high-pressure gas passes through the outlet valve plate 8 and enters the outlet chamber 14 through the outlet throughlet 13 for the first buffering. Then, it passes through two high-pressure gas holes 6 and is sent into the first buffer chamber 10 and the third buffer chamber 12 respectively. The gas in the first buffer chamber 10 is directly discharged into the exhaust port 15, while the gas in the third buffer chamber 12 passes through the second buffer chamber 11 and then enters the exhaust port 15. The separation of the second buffer chamber 11 and the third buffer chamber 12 is necessary to ensure the strength of the compression shell 2, so as to prevent the structural strength from decreasing due to excessively long cavities. The outlet chamber 14 and the two sets of buffer channels can make the high-pressure output gas form two buffers, reducing pulse and airflow noise.
[0014] See Figures 1-5 As shown, the exhaust port 15 has a thread at its root, and the valve plate 5 and the outer cover 3 have holes opposite to the exhaust port 15. The outer cover 3 is installed on the outside of the valve plate 5 by screws. One of the screws is connected to the thread through the aforementioned hole. A venting ring 17 is pressed inside the screw. A high-pressure copper pipe 4 for conveying high-pressure gas is connected to the venting ring 17. A venting hole 18 is opened in the venting ring 17, which is connected to the high-pressure copper pipe 4. The valve plate 5 also has an air inlet 7 connected to the piston hole 9. An air inlet valve plate is installed inside the air inlet 7.
[0015] By installing the vent ring 17, the outer cover 3 is installed and then pressed tightly to achieve copper pipe installation and ensure gas flow.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.
