[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types. Existing air compressors are very noisy, causing significant disturbance to workers.

[0003] Existing technologies, such as the high-efficiency silencer air compressor disclosed in patent number CN112796975A, include an air compressor body composed of a housing, an air valve, and a compression mechanism. The compression mechanism and the air valve are both connected to the top of the housing, with the air valve located on the right side of the compression mechanism. A heat dissipation layer is fitted onto the surface of the housing, and a sound-absorbing plate is fitted onto the surface of the heat dissipation layer. Sound-absorbing cotton is filled between the sound-absorbing plate and the heat dissipation layer. A base plate is fixedly connected to the bottom of the housing. A silencer is connected to both the output end of the air valve and the input end of the compression mechanism. A shock-absorbing mechanism is provided at the bottom of the housing. This solution solves the problem that existing air compressors radiate a large amount of aerodynamic noise, structural mechanical noise, drive motor noise, and multi-source overlapping noise, which can easily affect the health and lives of employees. This high-efficiency silencer air compressor has advantages such as improved noise reduction effect.

[0004] The compressors disclosed above cannot ensure effective heat dissipation of the motor while reducing noise. Therefore, we have designed a high-efficiency, noise-reducing air compressor. Summary of the Invention

[0006] The objective of this utility model can be achieved through the following technical solution: A high-efficiency, noise-reducing air compressor includes a compression tank and a motor unit. A support frame is installed at the top of the compression tank. The motor unit is fixed to the top of the compression tank by the support frame and bolts. A soundproof cover is provided at the top of the compression tank to cover the motor unit. A sound-absorbing aluminum plate is installed on the inner wall of the soundproof cover. A sound-absorbing cotton layer is provided on one side of the sound-absorbing aluminum plate. The sound-absorbing aluminum plate has a hollow double-layer structure. A heat-conducting column is installed through the inner cavity of the soundproof cover. The two ends of the heat-conducting column are located on both sides of the soundproof cover and connected to heat sinks. The heat-conducting column has a hollow structure and circular holes are opened on its surface.

[0008] In the aforementioned high-efficiency, noise-reducing air compressor, a pressure-reducing adjustment seat and a pressure display gauge are respectively installed at both ends of the pressure-reducing valve, and a flow regulating valve is connected to the air port of the pressure-reducing valve.

[0009] In the aforementioned high-efficiency, noise-reducing air compressor, a caster mounting base is installed on one side of the bottom end of the compression tank, and shock-absorbing casters are installed at both ends of the caster mounting base.

[0010] In the aforementioned high-efficiency, noise-reducing air compressor, a push rod frame is welded and installed on the side wall of the compression tank, and a rubber handle is installed at one end of the push rod frame.

[0011] In the aforementioned high-efficiency silencer air compressor, four silencer aluminum plates are attached and installed around the perimeter of the soundproof cover.

[0012] Compared with the prior art, the advantages of this utility model of a high-efficiency silencer air compressor are as follows: a soundproof cover is used to cover the motor part, and a soundproof aluminum plate is installed on the inner wall of the soundproof cover. A soundproof cotton layer is set on one side of the soundproof aluminum plate. The soundproof aluminum plate has a hollow double-layer structure. A heat-conducting column is installed through the inner cavity of the soundproof cover. The two ends of the heat-conducting column are located on both sides of the soundproof cover and connected to heat sinks.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] As shown in Figures 1, 2 and 3, this utility model discloses a high-efficiency, noise-reducing air compressor.

[0019] Example 1: An air compressor includes a compression tank 1 and a motor unit 2. A support frame 3 is installed at the top of the compression tank 1. The motor unit 2 is fixed to the top of the compression tank 1 by the support frame 3 and bolts. A soundproof cover 6 is provided at the top of the compression tank 1 to cover the motor unit 2. A sound-absorbing aluminum plate 12 is installed on the inner wall of the soundproof cover 6. A sound-absorbing cotton layer 11 is provided on one side of the sound-absorbing aluminum plate 12. The sound-absorbing aluminum plate 12 has a hollow double-layer structure. A heat-conducting column 13 is installed through the inner cavity of the soundproof cover 6. The two ends of the heat-conducting column 13 are located on both sides of the soundproof cover 6 and connected to heat sinks 15. The heat-conducting column 13 has a hollow structure and a circular hole 14 is opened on the surface of the heat-conducting column 13.

[0020] Among them, there are four sound-absorbing aluminum plates 12, which are pasted and installed around the perimeter of the soundproof cover 6.

[0021] The purpose of this design is to cover the motor unit 2 with a soundproof cover 6, so that the noise generated by it is greatly absorbed by the sound-absorbing cotton layer 11 and the sound-absorbing aluminum plate 12 on the inside, and the sound waves penetrating the soundproof cover 6 are greatly reduced, thus achieving the effect of noise reduction. At the same time, the heat generated by the operation of the motor unit 2 is transferred to the heat sink 15 to achieve heat dissipation by utilizing the principle of heat conduction.

[0022] In this design, although the motor unit 2 is covered by the soundproof cover 6, there is a gap that connects to the outside air due to the surface structure of the compression tank 1 and the setting of the support frame 3, thus realizing an air flow channel.

[0023] Based on Embodiment 1, as shown in Figures 1 and 3, in order to better realize the exhaust operation, an exhaust pipe 7 is welded to the exhaust port on one side of the top of the compression tank 1. A filter column 16 is installed at one end of the exhaust pipe 7, and a pressure reducing valve 17 is installed at one end of the filter column 16. A pressure reducing adjustment seat 8 and a pressure display gauge 18 are respectively installed at both ends of the pressure reducing valve 17, and a flow regulating valve 19 is connected to the air port of the pressure reducing valve 17.

[0024] Based on Embodiment 1, as shown in Figure 1, in order to facilitate the movement of the compression tank 1 and make it easy to transport and move, a caster mounting seat 4 is installed on one side of the bottom of the compression tank 1, and shock-absorbing casters 5 are installed at both ends of the caster mounting seat 4. A push rod frame 9 is welded and installed on the side wall of the compression tank 1, and a rubber handle 10 is installed at one end of the push rod frame 9.
