Description

Technical Field

[0001] This application relates to the technical field of compressors, and more particularly to a compressor. Background Technology

[0002] A compressor is a device used to compress gas, and its structure is similar to that of a water pump. It is mainly a device that converts mechanical energy into gas pressure energy. Compressors have a wide range of applications, including household appliances, installation and maintenance equipment, and even production line manufacturing machinery.

[0003] Currently, there is a type of dual-cylinder air compressor on the market. Its compressor uses a single motor to drive two pump heads, which is a single-motor dual-cylinder layout. Its biggest structural feature is that the two cylinders are placed at both ends of the motor shaft, thus forming a compressor layout with two pump heads.

[0004] Regarding the aforementioned technologies, the inventors believe that because the two cylinders operate separately and the cavities within the cylinders are not interconnected, there may be errors in the compressor output. Utility Model Content

[0005] In order to reduce the output error of the compressor, this application provides a compressor.

[0006] The compressor provided in this application adopts the following technical solution:

[0007] A compressor includes two compression assemblies 1, a connecting shell 2, and a dual-head motor 3. Each compression assembly 1 includes a housing 11, a cam 12, a piston 13, and a connecting rod 14. The two housings 11 are respectively disposed on both sides of the connecting shell 2. The dual-head motor 3 is disposed inside the connecting shell 2. Each housing 11 has an inner cavity 111. The cam 12 is located inside the inner cavity 111 and is connected to the output shaft of the motor. The connecting rod 14 is rotatably connected to the cam 12. The piston 13 is disposed at the end of the connecting rod 14 away from the cam 12. A square shell 112 is disposed on the housing 11. A circular ring 1121 is disposed inside the square shell 112. The piston 13 is slidably connected to the circular ring 1121. A connecting cover 113 is provided on the square shell 112. Air outlets 1131 are opened on both sides of the connecting cover 113. A connecting pipe 1132 is disposed on the side of the two connecting covers 113 that are close to each other.

[0008] By using the above technical solution, the chambers inside the two connecting covers 113 are connected by setting a connecting pipe 1132, so that the air pressure in the two chambers can be exchanged, thereby reducing the output error of the compressor.

[0009] Optionally, a sealing plate 1133 is provided between the square shell 112 and the connecting cover 113. The sealing plate 1133 has an air hole 11331. The connecting cover 113 has an air cavity 1134 inside. The air hole 11331 and the air cavity 1134 are interconnected.

[0010] Through the above technical solution, by setting a sealing plate 1133, the connecting cover 113 and the square shell 112 are separated, and the air hole 11331 connects the connecting cover 113 and the square shell 112. The sealing plate 1133 reduces the air outlet space and facilitates air compression.

[0011] Optionally, the connecting pipe 1132 is a tee pipe.

[0012] The above technical solution allows for the use of a plug to seal the air outlet 1131, which can then be connected via a T-connector, reducing the number of air outlets 1131 and increasing the compressor's output efficiency.

[0013] Optionally, a sealing ring 11332 is provided between the sealing plate 1133 and the connecting cover 113.

[0014] The above technical solution uses a sealing ring 11332 to seal between the sealing plate 1133 and the connecting cover 113, thereby improving the sealing performance.

[0015] Optionally, a fan 4 is provided in the inner cavity 111 of the housing 11, and the fan 4 is connected to the output shaft of the dual-head motor 3.

[0016] Through the above technical solution, the fan 4 dissipates heat from the inner cavity 111 of the housing 11.

[0017] Optionally, a dustproof net 5 is provided at the opening of the inner cavity 111 of the housing 11.

[0018] Through the above technical solution, the dustproof net 5 blocks external dust and gravel, reducing the risk of internal damage.

[0019] Optionally, the outer peripheral wall of the piston 13 is provided with a wear-resistant ring 131.

[0020] The service life of piston 13 can be increased by replacing the wear ring 131 using the above technical solution.

[0021] The beneficial effects of this utility model are as follows: by setting the connecting pipe 1132, the chambers in the two connecting covers 113 are connected, thereby allowing the air pressure in the two chambers to be interconnected, thereby reducing the output error of the compressor.
