DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: an air compressor with a heat dissipation structure, including a tank body 3 for storing gas, a group of supporting parts are arranged around the bottom of the tank body 3, supported on the ground, and the supporting parts adopt rubber foot pads to improve the shock absorption effect of the air compressor when working, and improve the wear resistance of the supporting parts. The top of the tank body 3 is installed and connected with a lower shell 2, and the upper part of the lower shell 2 is threadedly connected with an upper shell 1 for installing various operating parts of the air compressor.

[0024] refer to Figure 1 , Figure 2 The upper shell 1 and the lower shell 2 are provided with heat dissipation ports on the front and rear opposite sides, which play a role in cooling the internal components when the air compressor is started. A driving unit 4 is installed in the middle of the lower shell 2. The driving unit 4 is preferably a dual-axis motor. The driving unit 4 is provided with two output ends, namely a first output end arranged close to the front heat dissipation port and a second output end arranged away from the front heat dissipation port;

[0025] An air guide portion 5 is provided on one side of the first output end for guiding the front heat dissipation port, so that the heat dissipation airflow enters the air compressor from the front heat dissipation port in an orderly manner and is discharged from the rear heat dissipation port, thereby performing the internal heat dissipation process while the air compressor is running.

[0026] Specifically, refer to Figure 3The air guide part 5 includes a first heat dissipation fan 9, which is fixedly connected to the first output end of the driving part 4. When the driving part 4 is started, the air from the front heat dissipation port will form a heat dissipation airflow under the action of the first heat dissipation fan 9 and enter between the upper shell 1 and the lower shell 2 to perform the heat dissipation process inside the air compressor.

[0027] The wind guide portion 5 also includes a first wind guide cover 51 and a second wind guide cover 52. The first wind guide cover 51 and the second wind guide cover 52 constitute an annular wind guide cover for limiting the flow direction of the introduced airflow. An outer ring 53 and an inner ring 54 are respectively fixed on both sides where the first wind guide cover 51 is connected to the second wind guide cover 52. Similarly, an inner ring 54 and an outer ring 53 are respectively fixed on both sides where the second wind guide cover 52 is connected to the first wind guide cover 51 at positions corresponding to the outer ring 53 and inner ring 54 of the first wind guide cover 51, so that the inner ring 54 of the first wind guide cover 51 is snapped into the inner part of the outer ring 53 of the second wind guide cover 52, and the inner ring 54 of the second wind guide cover 52 is snapped into the inner part of the outer ring 53 of the first wind guide cover 51. After the corresponding outer ring 53 and inner ring 54 are snapped, the outer ring 53 and inner ring 54 connected are fixed by screws to achieve the fastening installation of the wind guide portion 5.

[0028] A fixing part 11 is provided on the upper and lower sides of the outside of the driving part 4, and a bracket 6 is connected to the other end of the fixing part 11. The inside of the bracket 6 is provided with a conventional air compression component, which will not be described in detail here. A belt transmission part is provided on one side of the bracket 6 close to the second output end of the driving part 4.

The diameter of the driving wheel 10 is smaller than the diameter of the driven wheel 8. When the driving part 4 is started, the second output end drives the driving wheel 10 to rotate, and the driving wheel 10 then drives the driven wheel 8 to rotate through the belt 7, thereby realizing the subsequent air compression process. The use of the belt 7 is different from the gear transmission, which not only achieves the noise reduction effect, but also improves the service life of the driving wheel 10 and the driven wheel 8.

[0030] Among them, reference Figure 5 A second cooling fan 12 is integrally provided on one side of the driving wheel 10 close to the driving part 4, and the second cooling fan 12 is arranged on the outside of the belt 7. When the driving wheel 10 drives the belt 7 to run, the driving wheel 10 also drives the second cooling fan 12 to rotate synchronously. In addition to the first cooling fan 9 providing a certain heat dissipation effect on the belt transmission part, the addition of the second cooling fan 12 assists and strengthens the heat dissipation of the belt transmission part, effectively improving the service life of the belt 7.

[0031] It should be noted that the fixing part 11 is a detachable structure, and the fixing part 11 includes a fixing rod 111 fixed to the outside of the driving part 4, and a sleeve rod 112 fixedly arranged on the bracket 6. The sleeve rod 112 is used to be sleeved on the outside of the fixing rod 111, and when the belt transmission part and the bracket 6 are installed, the fixing part 111 is detachable. Figure 3 When the belt conveyor is in the position shown, the fixing nut 113 is screwed onto one end of the fixing rod 111 to limit and fix the sleeve rod 112, thereby completing the convenient installation of the belt conveyor.
