Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The left and right sides of the bottom of the shell 1 are symmetrically welded with connecting blocks 2. The air storage tank 3 is arranged between the tops of the connecting blocks 2. The air compressor 4 is arranged in the middle of the upper inner part of the shell 1. The bottom of the air compressor 4 is connected and communicated with the top of the air storage tank 3. The air compressor 4 can store the compressed air in the air storage tank 3. The upper part of the shell 1 is provided with an air cooling component 5, and the bottom of the shell 1 is provided with a shock absorbing component 6.

The first support frames 51 are welded to the upper parts of the front and rear sides of the shell 1, and the outer sides of the first support frames 51 are provided with filters 52. The first fans 53 are arranged at intervals inside the first support frames 51. When the first fans 53 are working, they can speed up the air flow inside the shell 1, thereby cooling the air compressor 4.

[0038] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The shock absorbing assembly 6 includes a guide rod 61, a support foot 62, a rubber pad 63 and a first spring 64. The left and right sides of the bottom of the shell 1 are symmetrically welded with guide rods 61. Support feet 62 are slidably provided between the lower parts of the two corresponding guide rods 61 on the left and right. Rubber pads 63 are provided on the left and right sides of the bottom of the support foot 62. The rubber pad 63 has an anti-slip effect. The first spring 64 is wound around the guide rod 61. The two ends of the first spring 64 are respectively connected to the shell 1 and the support foot 62. The first spring 64 has a shock absorbing effect.

[0039] When people need to use the device, first put the device in the designated position, the rubber pad 63 can play an anti-slip role, and then start the air compressor 4 and the first fan 53. The air compressor 4 can absorb a large amount of external air, and then pressurize the air and store it in the air tank 3. People can use the pressurized air in the air tank 3 to perform other work. At this time, the first fan 53 on the rear side will blow air into the shell 1, and the first fan 53 on the front side will discharge the air inside the shell 1 to the outside, thereby accelerating the air flow inside the shell 1 to achieve the purpose of heat dissipation of the air compressor 4. The filter 52 can prevent dust from sticking to the first fan 53. At the same time, the air compressor 4 will vibrate when working. At this time, the first spring 64 will deform adaptively, thereby achieving a shock-absorbing effect and reducing noise. When people do not need to use the device, they can just turn off the air compressor 4 and the first fan 53.

The third condenser 75 is located in front of the first fan 53 on the rear side. When the condensate flows inside the first condenser 71, the second condenser 73 and the third condenser 75, it can cool the air blown into the outer shell 1 and enhance the cooling effect. A second fan 76 is provided on the upper inner side of the outer shell 1, and the second fan 76 is located between the first condenser 71 and the air compressor 4.

[0042] Initially, there is condensate in the first condenser tube 71. When people start the air compressor 4, they can open the expansion valve 74 and then start the booster pump 72 and the second fan 76.

Then the condensate will return to the first condenser tube 71, and the second fan 76 can blow air upwards to dissipate the heat of the condensate, so that the condensate can be recycled. When people turn off the air compressor 4, they can turn off the booster pump 72 and the second fan 76, and then close the expansion valve 74.

[0044] When the condensate returns to the first condenser tube 71, the heat sink 82 can absorb the heat in the condensate to achieve the purpose of dissipating the heat of the condensate. The second fan 76 blows air upward to dissipate the heat of the heat sink 82. When people need to clean the heat sink 82, they can push the push rod 85 inward to squeeze the block 83 to move inward. The second spring 84 is compressed so that the block 83 no longer blocks the shell 1. Then people can pull the second support frame 81 upward to take it out, driving the heat sink 82 and the block 83 to move upward. When the block 83 is separated from the shell 1, When the clamping block 83 is completely reset, the second spring 84 returns to its original state, driving the clamping block 83 to move outward and reset, and then the push rod 85 is released. At this time, the heat sink 82 can be cleaned. After cleaning, the second support frame 81 is put back in place, driving the heat sink 82 and the clamping block 83 to move downward and reset. When the clamping block 83 contacts the outer shell 1, the outer shell 1 squeezes the clamping block 83 to move inward, and the second spring 84 is compressed.
