[0021] In the specific implementation process, as Figures 1 - 6 shown, it includes a host box body 1, an installation groove 2 is opened at the top of the host box body 1, an air inlet dust-proof net 3 is arranged on one side of the host box body 1, two support plates 4 are arranged at intervals on the top of the host box body 1, two installation platforms 5 are fixedly arranged at intervals between the two support plates 4, a circular frame 6 is fixed below the installation platform 5, a rotating shaft 7 is movably arranged on the installation platform 5, a plurality of heat dissipation blades 8 are installed at the bottom of the rotating shaft 7, and the two support plates 4 are both fixed on the host box body 1 through a plurality of screws 9.

[0022] An installation frame 10 is fixed on the installation platform 5, a first dust-proof net 11 is installed on the installation frame 10, a second dust-proof net 12 is installed between the two circular frames 6, and the first dust-proof net 11 and the second dust-proof net 12 can prevent external dust from falling into the host box body 1.

[0023] A first bevel gear 13 is installed at the top of each of the two rotating shafts 7. A transverse base 14 is fixed on the mounting table 5. A first transmission shaft 15 is movably arranged on the transverse base 14. A second bevel gear 16 is installed at one end of the first transmission shaft 15, and a third bevel gear 17 is installed at the other end of the first transmission shaft 15. The first bevel gear 13 meshes with the second bevel gear 16. A first longitudinal base 18 is fixed on the support plate 4. A second transmission shaft 19 is movably arranged on the first longitudinal base 18. Two fourth bevel gears 20 are installed at intervals on the second transmission shaft 19. The two fourth bevel gears 20 respectively mesh with the two third bevel gears 17. A motor 21 is installed on the support plate 4. The output end of the motor 21 is connected to the second transmission shaft 19 through a coupling. A second longitudinal base 28 is installed on the support plate 4. A one-way bearing 29 is movably arranged on the second longitudinal base 28. The second transmission shaft 19 is fixedly connected to the inner ring of the one-way bearing 29. The outer ring of the one-way bearing 29 is fixedly connected to a third transmission shaft 30. A fifth bevel gear 31 is installed on the third transmission shaft 30. A sixth bevel gear 32 is installed at the top of the reciprocating lead screw 25. The fifth bevel gear 31 meshes with the sixth bevel gear 32.

[0025] When dissipating heat, the staff only needs to start the motor 21 to rotate forward. Under the driving action of the first bevel gear 13, the second bevel gear 14, the third bevel gear 17 and the fourth bevel gear 20, several rows of heat dissipation blades will be driven to rotate, thereby quickly discharging the heat inside the main body case 1 to the outside. At the same time, due to the characteristic of the one-way rotation of the inner ring and the outer ring of the one-way bearing 29, when the second transmission shaft 19 rotates, the third transmission shaft 30 will not rotate.

[0026] A vertical seat 33 is fixed on one side of each of the two support plates 4. The vertical seat 33 is located on one side of the air inlet dust-proof net 3. The vertical seat 33 is fixedly connected to the main body case 1 through screws. A chute 34 is opened on one side of each of the two vertical seats 33. A sliding seat 22 is slidably arranged inside the chute 34. An installation plate 23 is fixed between the two sliding seats 22. A dust removal brush 24 is arranged on one side of the installation plate 23. The dust removal brush 24 is in contact with the surface of the air inlet dust-proof net 3. A reciprocating lead screw 25 is movably arranged inside the chute 34 through a bearing. The reciprocating lead screw 25 passes through the sliding seat 22, and the reciprocating lead screw 25 is threadedly connected to the sliding seat 22. The reciprocating lead screw 25 is galvanized to improve its service life.

[0027] Start the motor 21 to reverse. At this time, the second transmission shaft 19 will drive the entire one-way bearing 29 and the third transmission shaft 30 to rotate. Under the transmission action of the fifth bevel gear 31 and the sixth bevel gear 32, the reciprocating screw 25 will be driven to rotate. At this time, the slide seat 22 can drive the mounting plate 23 to slide along the slide groove 34. The dust removal brush 24 on one side of the mounting plate 23 can quickly scrape off the dust on the air inlet dust screen 3.

[0028] A card slot 26 is opened on one side of the stand 33, and a closing plate 35 is arranged on one side of the stand 33. A card block 27 is fixed on one side of the closing plate 35, and the card block 27 is engaged with the card slot 26. When it is not necessary to clean the air inlet dust screen 3, the start motor 21 moves the slide 22 to the lowest point, and then the closing plate 35 is inserted into the card slot 26. The closing plate 35 can prevent dust from entering the slide slot 34.

[0029] Working principle of the present invention: When installing the cooling fan of the computer host, the user only needs to fix the support plate 4 and the stand 33 to the host box 1 by screws 9 from the outside to complete the installation of the cooling fan. The operation is simple and convenient, and there is no need to open the host box 1. When heat dissipation is performed, the staff only needs to start the motor 21 to rotate forward. Under the transmission action of the first bevel gear 13, the second bevel gear 14, the third bevel gear 17 and the fourth bevel gear 20, the heat exhaust blades will be driven to rotate and the heat inside the mainframe box 1 will be quickly discharged to the outside. At the same time, due to the unidirectional rotation characteristics of the inner ring and the outer ring of the one-way bearing 29, when the second transmission shaft 19 rotates, the third transmission shaft 30 will not rotate; Start the motor 21 to reverse. At this time, the second transmission shaft 19 will drive the entire one-way bearing 29 and the third transmission shaft 30 to rotate. Under the transmission action of the fifth bevel gear 31 and the sixth bevel gear 32, the reciprocating screw 25 will be driven to rotate. At this time, the slide seat 22 can drive the mounting plate 23 to slide along the slide groove 34. The dust removal brush 24 on one side of the mounting plate 23 can quickly scrape off the dust on the air inlet dust screen 3.
