[0018] To realize the positioning installation of radiator 4 in the machine box 1, install the hanging box 9 in the top position in the machine box 1, and the upper part of the hanging box 9 is matched with the radiator 4, and the lower part of the hanging box 9 is provided with the fan 10 capable of blowing air upward, and the fan 10 can accelerate the air flow rate near the radiator 4, to improve the heat exchange efficiency of the radiator 4.

[0019] The cleaning spray pipe 11 is also arranged in the hanging box 9 between the radiator 4 and the fan 10, and the cleaning spray pipe 11 is arranged along the width direction of the radiator 4, and the cleaning spray pipe 11 can reciprocate along the length direction of the radiator 4 and clean the radiator 4 in all directions. Corresponding to the position of the radiator 4, the water suction cover 12 is installed on the top of the machine box 1, and the waste water tank 13 is also arranged on one side of the machine box 1, and the water suction cover 12 and the waste water tank 13 are connected through the water suction pipe 14, and the mesh cover 29 capable of discharging gas is arranged on the top of the waste water tank 13.

[0020] When the radiator 4 is cleaned, the radiator 4 does not need to be disassembled, and the air compressor does not need to be stopped, and can still be in the use state, the cleaning spray pipe 11 sprays water mist upward to wash and clean the radiator 4, and the airflow blown upward by the fan 10 can drive the water mist and dirt to gather upward to the water suction cover 12, and finally enter the waste water tank 13 through the water suction pipe 14.

[0021] The top of the wastewater tank 13 is provided with a mesh cover 29, which allows the internal flowing gas to be smoothly discharged and carries the corresponding wastewater mist into the wastewater tank 13. When the air compressor is normally used, the cleaning spray pipe 11 is fixed at one end of the bottom of the heat dissipation box 4, and the cleaning spray pipe 11 no longer sprays water mist. The fan 10 blows air to the heat dissipation box 4 in the upper position, and the air path channel connected through the water suction cover 12, the water suction pipe 14 and the wastewater tank 13 can achieve the corresponding heat dissipation function of the heat dissipation box 4. The setting of the hanging box 9 can effectively prevent the internal water mist from leaking out and prevent the water mist from damaging the electrical components inside the air compressor.

[0022] Further, in order to realize the movement of the cleaning spray pipe 11 at the bottom of the cleaning spray pipe 11, as shown, Figures 5-7 two rotating shaft rods 15 arranged side by side are installed in the hanging box 9, and each rotating shaft rod 15 is located at the bottom of the length direction of the heat dissipation box 4. The rotating shaft rod 15 is installed on the hanging box 9 through a bearing and can rotate relative to the hanging box 9.

[0023] Belt pulleys 16 are installed at the ends of the rotating shaft rods 15, and belt pulleys 16 on the same side of the rotating shaft rods 15 are cooperatively installed with a belt 17, that is, two belts 17 capable of synchronous rotation are installed between the two rotating shaft rods 15. Fixed seats 18 are arranged on the two belts 17, and the cleaning spray pipe 11 is installed between the fixed seats 18. When the rotating shaft rods 15 rotate, the cleaning spray pipe 11 can reciprocate and clean at the bottom of the heat dissipation box 4 through the transmission of the belt pulleys 16 and the belts 17.

[0024] In order to realize the cleaning and washing of the cleaning spray pipe 11 to the upper heat dissipation box 4, a plurality of spray holes 19 arranged along the length direction are formed at the top of the cleaning spray pipe 11, and the spray holes 19 can spray water mist upward to clean the heat dissipation box 4. In order to ensure the continuous supply of cleaning water during the movement of the cleaning spray pipe 11, a two-way valve is installed in one of the fixed seats 18, one outlet of the two-way valve is connected with the cleaning spray pipe 11, and the other outlet of the two-way valve is installed with a telescopic hose 20. The hose 20 can be connected with a cleaning water source with a water pump, can adaptively stretch and contract with the movement of the cleaning spray pipe 11, will not affect the components inside the device, and at the same time can provide the necessary cleaning water for cleaning.

[0025] In order to realize the power drive of the reciprocating movement of the cleaning spray pipe 11, a drive motor 21 is further installed at the end of one of the rotating shaft rods 15, the output shaft of the drive motor 21 is connected with the rotating shaft rod 15, and the drive motor 21 can drive the cleaning spray pipe 11 to move between the rotating shaft rods 15.

[0026] Further, in order to realize the continuous feeding of the cleaning water into the hose 20, the cabinet 1 is provided with a pneumatic three-way ball valve 22, one side of the cabinet 1 is provided with a high-pressure pump 23 and a cleaning water tank 24, the high-pressure pump 23 is connected with one inlet of the pneumatic three-way ball valve 22 through a gas supply pipe 25, the cleaning water tank 24 is connected with another inlet of the pneumatic three-way ball valve 22 through a water supply pipe 26, and the hose 20 is connected with the outlet of the pneumatic three-way ball valve 22. The cleaning water tank 24 is filled with cleaning water for washing and cleaning the radiator 4, the high-pressure pump 23 can suck the cleaning water and pressurize the cleaning water to be fed into the cleaning spray pipe 11 while outputting high-pressure gas, so as to ensure that the cleaning spray pipe 11 can continuously spray high-pressure water mist upward to the radiator 4 to clean the radiator 4 from all aspects.

[0027] In order to collect the water mist mixed with dirt on the upper part of the radiator 4, the water suction cover 12 is arranged in a conical shape with a large lower part and a small upper part. The water suction cover 12 with the above structure can converge and uniformly guide the water mist to be collected into the water suction pipe 14. However, the water mist contacts the inner wall of the water suction cover 12 to form liquid drops during the rising process, which gradually accumulates and flows down along the inner wall, and then re-pollutes the radiator 4 or affects the drying degree of the internal components. In order to solve the above problem, as shown in Figure 8 a water collecting ring groove 27 is arranged on the inner periphery of the bottom of the water suction cover 12. The water collecting ring groove 27 is connected with the water suction pipe 14 through a drain pipe 28, and the drain pipe 28 is arranged obliquely downward relative to the water suction cover 12. The bottom wall of the water collecting ring groove 27 can also be arranged obliquely downward. The liquid drops collected in the water collecting ring groove 27 flow into the drain pipe 28, and under the action of gravity, the obliquely arranged drain pipe 28 discharges the liquid drops in the internal part to the water suction pipe 14, thereby avoiding the secondary pollution or dampness of the internal structures of the device caused by the liquid drops containing dirt.

[0028] In order to separate and recycle the liquid drops containing dirt entering the waste water tank 13, as shown in Figure 9 a filter screen plate 30 and a waste water box 31 are arranged in the waste water tank 13. The filter screen plate 30 is located on the upper part of the waste water box 31, and the filter screen plate 30 can filter and intercept the dirt. The cleaning water entering the waste water tank 13 through the water suction pipe 14 can pass through the filter screen plate 30 and enter the waste water box 31. The filter screen plate 30 is used to accumulate solid dirt, and the waste water box 31 is used to contain liquid dirt. The solid-liquid separation and recycling of the dirt in the waste water tank 13 can be realized by respectively pulling out the filter screen plate 30 and the waste water box 31.

[0029] Further, in order to change the washing angle of the water mist sprayed by the cleaning spray pipe 11 during the reciprocating movement of the cleaning spray pipe 11 at the bottom of the radiator 4, the washing and cleaning degree of the radiator 4 can be improved, as shown in Figure 10As shown, the cleaning spray pipe 11 is rotatably mounted between the fixed seats 18 by bearings, and the cleaning spray pipe 11 can rotate relative to the fixed seats 18, and the cleaning water can still be continuously supplied during rotation. A tension spring 32 is further connected between the cleaning spray pipe 11 and the fixed seat 18, which always limits the tendency of the cleaning spray pipe 11 to rotate relative to the fixed seat 18.

[0030] The lower end of the cleaning spray pipe 11 is provided with a downwardly protruding swing rod 33, and the tension spring 32 is arranged between the two sides of the swing rod 33 and the fixed seat 18. Corresponding to the position of the swing rod 33, a comb rack 34 is further mounted in the hanging box 9, and the comb rack 34 is arranged along the length direction of the belt 17. When the belt 17 drives the cleaning spray pipe 11 to move, the swing rod 33 can be in contact with each comb on the comb rack 34, and drive the cleaning spray pipe 11 to reciprocatingly swing relative to the fixed seat 18 against the elastic force of the two tension springs 32. During the movement, the angle of the cleaning spray pipe 11 to the water mist sprayed on the heat dissipation box 4 can be repeatedly changed, so as to realize the omnibearing washing of the heat dissipation box 4.

[0031] The air compressor machine capable of automatically cleaning the radiator provided by the utility model can continuously keep the radiator clean, reduce the overheating failure caused by poor heat dissipation, improve the stability and reliability of the whole air compressor machine system, ensure the continuity of the production process and the product quality, solve the problems of complex cleaning and low efficiency of the radiator in the prior art, improve the overall performance and use experience of the air compressor machine through intelligent and environmentally friendly and energy-saving design, and bring remarkable economic benefits and social benefits to industrial production and equipment maintenance.
