DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figure 1-Figure 4 , a corrosion-resistant and noise-reducing gas compressor, comprising.

[0022] A main body shell 1, a compression shell 2 is arranged inside the main body shell 1, a compression mechanism is arranged inside the compression shell 2, a gas compression cylinder 3 is fixedly connected to the bottom of the main body shell 1, and a corrosion-resistant spray paint is arranged inside the gas compression cylinder 3, and the corrosion-resistant spray paint can improve the corrosion resistance of the gas compression cylinder 3 and improve the service life of the gas compression cylinder 3;

[0023] One-way valves 4 are provided on both sides of the gas compression cylinder 3. The output end of the one-way valve 4 is connected to a sound-absorbing tube 5. A plurality of annular heat dissipation ports are provided on the gas compression cylinder 3. A driving motor 6 is provided on the main shell 1. The output end of the driving motor 6 runs through the main shell 1 and the compression shell 2. The flow directions of the two one-way valves 4 are opposite. The one-way valve 4 that flows from the inside of the gas compression cylinder 3 to the outside of the gas compression cylinder 3 corresponds to the outlet, and the one-way valve 4 that flows from the outside of the gas compression cylinder 3 to the inside of the gas compression cylinder 3 corresponds to the inlet. The sound-absorbing tube 5 can absorb noise.

[0024] The compression mechanism includes a rotating shaft 7, a linkage shaft 8 and a transmission gear 9. The rotating shaft 7 is rotatably connected to the inner wall of the compression shell 2, the linkage shaft 8 is rotatably connected to the output end of the rotating shaft 7, the transmission gear 9 is rotatably connected to the output end of the linkage shaft 8, a positioning rack 10 is fixedly connected to the inner wall of the compression shell 2, the transmission gear 9 is meshed with the positioning rack 10, a positioning slide rail 11 is fixedly connected to the inner wall of the compression shell 2, an extended-range rack 12 is slidably connected to the positioning slide rail 11, the extended-range rack 12 is meshed with the transmission gear 9, a transmission shaft 13 is fixedly connected to one side of the extended-range rack 12, a compression piston 14 is fixedly connected to the end of the transmission shaft 13 away from the extended-range rack 12, the compression piston 14 is slidably connected to the gas compression cylinder 3, and the output end of the drive motor 6 passes through the compression shell 2 and is connected to the rotating shaft 7 Connection, a connecting frame is fixedly connected to one side of the compression shell 2, and the connecting frame is fixedly connected to the gas compression cylinder 3. When the device is working normally, the rotating shaft 7 coaxially fixedly connected to the output end of the driving motor 6 rotates, and the linkage shaft 8 rotatably connected to the output end of the rotating shaft 7 rotates. When the linkage shaft 8 rotates, the transmission gear 9 will reciprocate. Since the transmission gear 9 is engaged with the positioning rack 10, the transmission gear 9 will also rotate at this time. The displacement distance of the transmission gear 9 will drive the range-extending rack 12 to move. At the same time, the self-rotation of the transmission gear 9 will also cause the range-extending rack 12 to move. Therefore, the stroke of the range-extending rack 12 will be twice that of the positioning rack 10. Through the connection of the transmission shaft 13, the compression piston 14 will reciprocate in the gas compression cylinder 3, thereby compressing the gas.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] The gas compression cylinder 3 is provided with corrosion-resistant spray paint, which can improve the corrosion resistance of the gas compression cylinder 3 and increase the service life of the gas compression cylinder 3;

[0027] The flow directions of the two one-way valves 4 are opposite. The one-way valve 4 that flows from the inside of the gas compression cylinder 3 to the outside of the gas compression cylinder 3 corresponds to the air outlet, and the one-way valve 4 that flows from the outside of the gas compression cylinder 3 to the inside of the gas compression cylinder 3 corresponds to the air inlet. The sound-absorbing pipe 5 can absorb noise.

[0028] When the device is working normally, the rotating shaft 7 coaxially fixedly connected to the output end of the driving motor 6 rotates, and the linkage shaft 8 rotatably connected to the output end of the rotating shaft 7 rotates. When the linkage shaft 8 rotates, the transmission gear 9 will reciprocate. Since the transmission gear 9 is meshed with the positioning rack 10, the transmission gear 9 will also rotate at this time. The displacement distance of the transmission gear 9 will drive the range-extending rack 12 to move. At the same time, the self-rotation of the transmission gear 9 will also cause the range-extending rack 12 to move. Therefore, the stroke of the range-extending rack 12 will be twice that of the positioning rack 10. Through the connection of the transmission shaft 13, the compression piston 14 will reciprocate in the gas compression cylinder 3, thereby compressing the gas.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
