Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] Please refer to Figures 1-6The utility model provides a technical solution: a compressed air supply device for a spray gun, comprising an air compressor 1, an air inlet end of the air compressor 1 is fixedly connected to an air inlet pipe 2, and the other end of the air inlet pipe 2 is fixedly connected to a filter box 3, and the end of the filter box 3 away from the air inlet pipe 2 is fixedly connected to the air inlet pipe 4, and a mounting frame is movably inserted on the top outer surface of the filter box 3, and a filter screen 5 is arranged inside the mounting frame, and a rack 6 is fixedly connected to the front and rear ends of the mounting frame facing the air inlet pipe 4. Two reciprocating screws 7 are rotatably penetrated on the top outer surface of the filter box 3, and the outer surface of the reciprocating screw 7 is threadedly connected with a threaded block 8, and the outer surfaces of the two threaded blocks 8 are fixedly connected to a connecting plate 9, and the outer surfaces of the two connecting plates 9 are rotatably connected to a rotating shaft 10, and a cleaning cylinder 11 is fixedly sleeved on the outer surface of the rotating shaft 10, and a cleaning brush is arranged on the outer surface of the cleaning cylinder 11. The fixed sleeve is provided with two transmission gears 12, and the two transmission gears 12 are movably engaged with the outer surfaces of the two racks 6 respectively. Specifically, air enters the filter box 3 through the air inlet pipe 4, filters the air through the filter screen 5, and enters the interior of the air compressor 1 through the air inlet pipe 2 for compression, and then is transported to the spray gun for use. The two reciprocating screws 7 drive the threaded block 8 to move during the rotation process, and the threaded block 8 drives the connecting plate 9 to move the transmission gear 12 and the cleaning barrel 11. The transmission gear 12 slides on the surface of the rack 6, so that the transmission gear 12 itself rotates, and the rotation of the transmission gear 12 drives the rotating shaft 10 to rotate the cleaning barrel 11, so that it can rotate while the cleaning barrel 11 moves, thereby cleaning the residual impurities on the surface of the filter screen 5 through the cleaning brush on the cleaning barrel 11, so that the filter screen 5 can be cleaned without frequently disassembling it.

[0027] In this embodiment, the top outer surface of the filter box 3 is fixedly connected to the connecting frame 13, and refrigeration fins 14 are installed inside the left and right sides of the connecting frame 13. Two motors 15 are fixedly installed on the top outer surface of the connecting frame 13, and the top inner wall of the connecting frame 13 is rotatably connected to two support shafts 16. The outer surfaces of the two support shafts 16 are fixedly sleeved with a number of blades 17. Specifically, the refrigeration end of the refrigeration fin 14 generates cold air toward the inside of the connecting frame 13. When the motor 15 is working, it drives the support shaft 16 to rotate and causes the blades 17 to rotate. The blades 17 generate wind force to blow the cold air toward the inside of the filter box 3, which can generate air with a certain cooling temperature and enter the air compressor 1, thereby cooling the inside of the air compressor 1 and preventing the air compressor 1 from being in a high temperature state for a long time and reducing its service life.

[0028] It is worth noting that in order to ensure that the motor 15 drives the blades 17 to rotate and generate effective convection, a plurality of through holes need to be opened on the top of the filter box 3.

[0029] In this embodiment, a first horizontal shaft 18 is rotated through the outer surface of the rear side of the connecting frame 13. The first horizontal shaft 18 is located on one side of the inner part of the connecting frame 13 and is fixedly connected to the first driven bevel gear 20. The outer surface of the support shaft 16 is fixedly sleeved with a first driving bevel gear 19. The first driving bevel gear 19 is movably engaged with the outer surface of the first driven bevel gear 20. Specifically, when the motor 15 is working, it drives the support shaft 16 to rotate, and the support shaft 16 drives the first driving bevel gear 19 thereon to rotate. The first driving bevel gear 19 drives the driven bevel gear 12 to rotate so that the first horizontal shaft 18 rotates.

[0030] In this embodiment, a fixed sleeve is provided on the top outer surface of the filter box 3, and a second horizontal shaft 22 is rotated through the outer surface of the rear side of the fixed frame 21. The second horizontal shaft 22 is located on one side inside the fixed frame 21 and is fixedly connected to a second driving bevel gear 25. The outer surface of the rear reciprocating screw rod 7 is fixedly provided with a second driven bevel gear 26. The second driving bevel gear 25 is movably engaged with the outer surface of the second driven bevel gear 26. Specifically, the second horizontal shaft 22 drives the second driving bevel gear 25 to rotate when it rotates, and when the second driving bevel gear 25 rotates, it drives the second driven bevel gear 26 to rotate, thereby rotating the reciprocating screw rod 7 at the rear side.

[0031] In this embodiment, a first transmission wheel 23 is fixedly mounted on the outer surfaces of the first transverse shaft 18 and the second transverse shaft 22, and a first belt 24 is wound around the two first transmission wheels 23. Specifically, when the first transverse shaft 18 rotates, the first transmission wheel 23 thereon is driven to rotate. Under the action of the first belt 24, the first transmission wheel 23 on the second transverse shaft 22 is rotated, thereby driving the second transverse shaft 22 to rotate.

[0032] In this embodiment, the top outer surfaces of the two reciprocating screw rods 7 are fixedly sleeved with a second transmission wheel 27, and a second belt 28 is wound around the two second transmission wheels 27. Specifically, when the reciprocating screw rod 7 on the rear side rotates, it drives the second transmission wheel 27 on it to rotate. Under the action of the second belt 28, the other second transmission wheel 27 rotates, thereby driving the other reciprocating screw rod 7 to rotate.

[0033] In this embodiment, a mounting plate is fixedly connected to the top outer surface of the mounting frame, and the mounting plate is fixedly connected to the top outer surface of the filter box 3 by bolts. Specifically, when the filter 5 needs to be replaced, the bolts are removed to disassemble the mounting plate and pull out the mounting frame.

[0034] In this embodiment, a receiving box is provided on the bottom outer surface of the filter box 3. Specifically, the scraped impurities are collected by the receiving box. The connection between the receiving box and the filter box 3 can be a snap-on or threaded connection.

[0035] In this embodiment, the cooling end of the refrigeration plate 14 faces the inside of the connecting frame 13, and the heating end of the refrigeration plate 14 faces the outside of the connecting frame 13. Specifically, the refrigeration plate 14 generates cold air to the inside of the connecting frame 13, and the hot air generated by the refrigeration plate 14 is discharged to the outside of the connecting frame 13.

[0036] Working principle: When the utility model is in use, air enters the filter box 3 through the air inlet pipe 4, is filtered by the filter screen 5, and enters the interior of the air compressor 1 through the air inlet pipe 2 for compression, and then is transported to the spray gun for use. When the motor 15 is working, it drives the support shaft 16 to rotate, and the support shaft 16 drives the first driving bevel gear 19 thereon to rotate. The first driving bevel gear 19 drives the driven bevel gear 12 to rotate so that the first horizontal shaft 18 rotates. When the first horizontal shaft 18 rotates, it drives the first transmission wheel 23 thereon to rotate. Under the action of the first belt 24, the first transmission wheel 23 on the second horizontal shaft 22 rotates, thereby driving the second horizontal shaft 22 to rotate. When the second horizontal shaft 22 rotates, it drives the second driving bevel gear 25 to rotate. When the second driving bevel gear 25 rotates, it drives the second driven bevel gear The wheel 26 rotates, thereby rotating the reciprocating screw rod 7 on the rear side, and the rotation of the reciprocating screw rod 7 on the rear side drives the second transmission wheel 27 on it to rotate. Under the action of the second belt 28, the other second transmission wheel 27 rotates, thereby driving the other reciprocating screw rod 7 to rotate. The two reciprocating screw rods 7 drive the threaded block 8 to move during the rotation, and the threaded block 8 drives the connecting plate 9 to move the transmission gear 12 and the cleaning barrel 11. The transmission gear 12 slides on the surface of the rack 6, causing the transmission gear 12 itself to rotate. The rotation of the transmission gear 12 drives the rotating shaft 10 to rotate the cleaning barrel 11, so that the cleaning barrel 11 can rotate while it moves, so that the residual impurities on the surface of the filter screen 5 are cleaned by the cleaning brush on the cleaning barrel 11, so that the filter screen 5 can be cleaned without frequently disassembling it.

[0037] The cooling end of the refrigeration plate 14 generates cold air toward the inside of the connecting frame 13. When the motor 15 is working, it drives the support shaft 16 to rotate and causes the blades 17 to rotate. The blades 17 generate wind force to blow the cold air toward the inside of the filter box 3, which can generate air with a certain cooling temperature and enter the air compressor 1, thereby cooling the inside of the air compressor 1 and preventing the air compressor 1 from being in a high temperature state for a long time and reducing its service life.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
