And the two connecting poles 82 are prevented from being short-circuited.

The working process and the principle thereof are as follows:

the original inner brush 61 and the outer brush 62 are always positioned on the same side as the spring one 69 under the action of the tensile force of the spring one 69, and the rolling cloth 71 is in an open state, so that the outer side surface of the gauze 5 is sealed, dust is prevented from entering a computer in the cabinet body 1 through the gauze 5, and the coil spring 73 is also in a loose state.

When the computer is started, the heat dissipation fan blows air outwards all the time to achieve heat dissipation, the computer runs, the CPU is heated, heat is transferred to the heat absorption plate 22 through the heat dissipater on the CPU, alcohol in the inner cavity of the heat absorption plate 22 absorbs part of the heat and then expands to push the second piston 211 to move upwards, air in the second upper cavity 212 is pressed into the first lower cavity 632 of the first piston cylinder 63, and then the first piston rod moves upwards, and as the driving rope 612 is fixedly connected with the fixing block 66 on the first piston rod, when the first piston rod extends, the inner brush 61 and the outer brush 62 can be pulled to slide towards the side opposite to the first spring 69, meanwhile, the coil spring 73 acts on the scroll 72, so that the scroll 72 rotates, the winding cloth 71 is gradually restored to be in a state of being wound on the scroll 72, and the gauze 5 is also gradually exposed in the air.

The gauze 5 can be cleaned when the inner brush 61 and the outer brush 62 slide.

Originally, two electric connecting columns 82 do not contact with the first long plate 83 and the second long plate 85, the blowing fan 9 is not started, when the connecting block 64 moves rightwards, the two electric connecting columns 82 firstly contact with the first long plate 83 and the second long plate 85, the blowing fan 9 is powered on and turned reversely at the moment, air is blown towards the gauze 5 on the front side, dust cleaned during the movement of the inner brush 61 and the outer brush 62 can be blown outwards, the situation that the cleaned dust enters the computer is avoided, the heat dissipation fan is always blown outwards, and therefore the dust can be led out outwards.

With the temperature rising, the connecting block 64 continues to move to the right, when the electric connection pole 82 is positioned between the first long plate 83 and the first short plate 84, the air supply fan 9 is powered off, when the winding cloth 71 is completely collected, the two electric connection poles 82 are respectively contacted with the first short plate 84 and the second short plate 86, the air supply fan 9 is powered on again, at the moment, the direction of the power-on current of the air supply fan 9 is changed, the air supply fan 9 is changed into the forward rotation, low-temperature air is blown to the computer and is consistent with the wind direction of the heat dissipation fan, flowing wind from the front to the back is formed in the cabinet body 1, and the heat dissipation of the computer is realized.

When the computer is closed, the heat dissipation fan is closed, the temperature of the CPU is reduced, the degree of alcohol expansion is reduced, the pressure applied to the second piston 211 is reduced, the second piston 211 moves downward, the first piston rod cannot keep an extended state, the elastic force of the first spring 69 pulls the return rope 613 downward, and the elastic force of the first spring 73 is smaller than that of the first spring 69, so that the first spring 69 can pull the inner brush 61 and the outer brush 62 to return after the return rope 613 passes through the second fixed pulley 67 and the third fixed pulley 68 to change the direction under the condition of overcoming the elastic force of the first spring 73, and the outer brush 62 pulls the rolling cloth 71 to expand again to seal the front side of the gauze 5.

In the resetting process, the two electric connecting columns 82 are respectively contacted with the first long plate 83 and the second long plate 85, the air supply fan 9 is turned over again, the inner brush 61 and the outer brush 62 in the resetting process are matched to clean the gauze 5 on the front side again, and the gauze 5 on the front side is subjected to air inlet in a long time, so that dust is more easily attached to the gauze 5 with the air inlet, the gauze 5 on the front side needs to be cleaned again after the computer is turned off, and the dust is further prevented from being attached to the gauze 5 on the front side.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
