[0034] Below is the accompanying drawings Figures 1 to 4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0035] like Figure 1-4 As shown, an integrated air compressor with good cooling effect includes a balancing base 1, and an air storage tank 2, a cooling mechanism 3, a water cooling mechanism 4 and a compression mechanism 6 arranged on the balancing base 1;

[0036] The gas outlet end of the gas storage tank 2 is connected to the gas inlet end of the compression mechanism 6 through a pipeline. The gas storage tank 2 is used to deliver air to the compression mechanism 6, and the compression mechanism 6 is used to compress the air delivered by the gas storage tank 2 to output compressed gas;

[0037] The liquid outlet of the water cooling mechanism 4 is connected to the liquid inlet of the compression mechanism 6 through a pipeline, and the water cooling mechanism 4 is used to cool the compression mechanism 6 and the compressed gas output by the compression mechanism 6 by water;

[0038] The liquid outlet end of the compression mechanism 6 is connected to the liquid inlet end of the cooling mechanism 3 through a pipeline, and the liquid outlet end of the cooling mechanism 3 is connected to the liquid inlet end of the water cooling mechanism 4 through a pipeline. The cooling mechanism 3 is used to cool the coolant flowing out of the compression mechanism 6 and transport the cooled coolant to the water cooling mechanism 4.

[0039] The compression mechanism 6 and the compressed gas output by the compression mechanism 6 are cooled by water through the water cooling mechanism 4, and the coolant flowing out of the compression mechanism 6 is cooled by the cooling mechanism 3, and the cooled coolant is transported to the water cooling mechanism 4, so that the coolant can be recycled, thereby integrating the water cooling mechanism on the air compressor, and there is no need to purchase a water cooling mechanism separately when using it.

[0040] like Figure 3 As shown, the compression mechanism 6 includes a drive motor 61, a crank transmission unit 62 and a first compression pump 63 and a second compression pump 65. The crank transmission unit 62 includes two synchronous crank transmission rods whose lower ends are V-shaped and intersect with each other. The upper ends of the two synchronous crank transmission rods are respectively connected to the power parts of the first compression pump 63 and the second compression pump 65. The crankshaft at the intersection of the two synchronous crank transmission rods is connected to the drive shaft of the drive motor 61.

[0041] Furthermore, a belt transmission unit 64 for transmitting power through a belt and two pulleys is provided between the driving motor 61 and the crank transmission unit 62 , and a noise reduction cover 66 for wrapping the belt transmission unit 64 is provided on the outside of the belt transmission unit 64 .

[0042] Specifically, the belt drive unit 64 operates smoothly and with low noise. It has a simple structure, simple manufacturing, and low cost. It does not require lubrication, buffering, or shock absorption, and is easy to install and maintain. Furthermore, the noise reduction cover 66 not only reduces the loudness of the noise, but also ensures the safe operation of the drive motor 61.

[0043] like Figure 2 and 4 As shown, the water cooling mechanism 4 includes a water pump 41, a primary water cooling pipe 42, a gas-liquid separator 43, a secondary water cooling pipe 44 and an exhaust pipe 45;

[0044] The gas outlet end of the gas storage tank 2 is connected to the gas inlet end of the first compression pump 63 through a pipeline. The gas outlet end of the first compression pump 63 is connected to the gas-liquid separator 43 through the primary water-cooling pipe 42. The gas outlet pipe of the gas-liquid separator 43 is connected to the gas inlet end of the second compression pump 65 through a pipeline. The second compression pump 65 is connected to the exhaust pipe 45 through the secondary water-cooling pipe 44.

[0045] The liquid outlet of the water pump 41 is connected to the liquid inlet of the primary water cooling pipe 42 and the first compression pump 63 through a pipeline. The liquid outlet of the primary water cooling pipe 42 is connected to the liquid inlet of the secondary water cooling pipe 44 through a pipeline. The liquid outlet of the secondary water cooling pipe 44 is connected to the liquid inlet of the cooling mechanism 3 through a pipeline. The liquid outlet of the cooling mechanism 3 is connected to the liquid inlet pipeline of the water pump 41 through a pipeline.

[0046] The liquid outlet of the first compression pump 63 is connected to the liquid inlet of the second compression pump 65 through a pipeline, and the liquid outlet of the second compression pump 65 is connected to the pipeline connecting the secondary water cooling pipe 44 and the cooling mechanism 3 through a pipeline.

[0047] Specifically, the air storage tank 2 transports the external air to the first compression pump 63 for compression, and the air is transported to the primary water-cooling pipe 42 after being compressed by the first compression pump 63. The gas compressed by the first compression pump 63 is cooled by the coolant in the primary water-cooling pipe 42 and then transported to the gas-liquid separator 43. The gas-liquid separation is performed in the gas-liquid separator 43, and the separated compressed gas enters the second compression pump 65 for compression. After being compressed by the second compression pump 65, it is transported to the secondary water-cooling pipe 44 for cooling. The gas compressed by the second compression pump 65 is cooled by the coolant in the secondary water-cooling pipe 44 and then transported to the exhaust pipe 45 for discharge. In this process, continuous compression is performed by the first compression pump 63 and the second compression pump 65, which can improve the compression efficiency and exhaust volume.

[0048] It is worth noting that the water pump 41 transports the external coolant to the primary water-cooling pipe 42 and the first compression pump 63 to cool the compressed gas in the primary water-cooling pipe 42 and the first compression pump 63. The coolant passes through the primary water-cooling pipe 42 and the first compression pump 63 and is transported to the secondary water-cooling pipe 44 and the second compression pump 65 respectively to cool the compressed gas in the secondary water-cooling pipe 44 and the second compression pump 65. The coolant passes through the secondary water-cooling pipe 44 and the second compression pump 65 and is transported to the cooling mechanism 3 for cooling. The coolant after cooling by the cooling mechanism 3 is transported to the water pump 41 to realize the recycling of the coolant. Preferably, the coolant is water, which can reduce the cooling cost.

[0049] like Figure 2 and 4 As shown, the cooling mechanism 3 includes a condenser 31 and a water tank 32;

[0050] The liquid outlet end of the secondary water cooling pipe 44 is connected to the liquid inlet end of the condenser 31 through a pipeline, the liquid outlet end of the condenser 31 is connected to the liquid inlet end of the water tank 32 through a pipeline, and the liquid outlet end of the water tank 32 is connected to the liquid inlet pipeline of the water pump 41 through a pipeline.

[0051] Specifically, the coolant flowing out of the secondary water-cooling pipe 44 is transported to the condenser 31 through the pipeline, and is transported to the water tank 32 after being cooled by the condenser 31. Then, the cooled coolant is transported to the water pump 41 through the water tank 32, thereby realizing the recycling of the coolant and reducing waste.

[0052] like Figure 1 As shown, a Y-type filter 33 is installed on the pipeline connecting the water tank 32 and the water pump 41.

[0053] Specifically, the Y-type filter 33 can filter the coolant after cooling the condenser 31, thereby preventing impurities in the recycled coolant from mixing into the gas, which is beneficial to improving the purity of the gas and increasing the service life of the equipment.

[0054] like Figure 4 As shown, a drainage interface 11 is provided on the side wall of the leveling base 1 , and the liquid outlet end of the gas-liquid separator 43 is connected to the drainage interface 11 through a pipeline.

[0055] Specifically, since the liquid separated by the gas-liquid separator 43 may contain impurities such as oil, in order to prevent the separated liquid from contaminating the coolant, the separated liquid needs to be discharged through the drainage interface 11.

[0056] like Figure 1 As shown, a precision filter 21 is installed on the pipeline connecting the air storage tank 2 and the first compression pump 63.

[0057] Specifically, by providing the precision filter 21 , the purity of the gas entering the first compression pump 63 can be further improved, thereby reducing the impact of gas impurities during the gas compression process, which is beneficial to increasing the service life of the equipment.

[0058] like Figure 2 As shown, the first-level water-cooling pipe 42 and the second-level water-cooling pipe 44 are both provided with a pressure gauge and a safety valve.

[0059] Specifically, the air pressure in the pipe can be detected by the provided pressure gauge, and the provided safety valve is used for emergency braking when the air pressure in the pipe exceeds a threshold value, which plays an important protective role in personal safety and air compressor operation.

[0060] like Figure 1 As shown, it also includes an electric control box 5 arranged on the balancing base 1, and the electric control box 5 is used to control the operation of the gas storage tank 2, the cooling mechanism 3, the water cooling mechanism 4 and the compression mechanism 6.

[0061] Specifically, the provided electric control box 5 can facilitate user operation.

[0062] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
