The cylinder 21 is provided with a one-way intake valve 24 for introducing air into the cylinder 21 and a first one-way exhaust valve 25 for exhausting air from the cylinder 21. The one-way air intake valve 24 is connected to the inside of the lower part of the computer main body 10 through a soft rubber hose for allowing the cylinder 21 to move up and down in the water tub 20. As shown in fig. 2, the end of the first one-way vent valve 25 connected to the cylinder 21 is the air inlet end of the first one-way vent valve 25, the air inlet end of the first one-way vent valve 25 is provided with a filter cotton 26, the filter cotton 26 is used for filtering dust, the first one-way vent valve 25 is communicated with the inner side of the top of the computer mainframe 10 through a soft rubber tube, so that the cylinder 21 can move up and down in the water tank 20.

After the dust collection box 30 is filled with a mixture of gas and dust, when the piston 22 presses the valve core of the pressing valve again, the second one-way gas outlet valve 31 is opened, the mixture of the gas and the dust in the dust collection box 30 can be discharged into the fermentation tank 40 from the dust discharge pipe 32, on one hand, the oxygen in the gas can accelerate the fermentation of microorganisms in the fermentation tank 40, on the other hand, the dust and waste are utilized, and the dust is introduced into the fermentation tank 40 to form organic sludge with rich nutrition, so that flowers and the like can be planted.

When the dump box 60 is full of water, the dump box 60 starts to discharge water, the water flow impacts the cylinder 21 to make the cylinder 21 instantaneously move to the lowest position and make the piston 22 press the valve core of the pressing valve, the pressing valve 27 is opened, the gas containing dust enters the dust collection box 30 at a large flow rate, and the cylinder 21 automatically discharges dust. After the water is drained from the dump box 60, the cylinder 21 moves upward under the buoyancy of the water, and the cylinder 21 sucks the dust-containing gas in the computer main unit 10. The cylinder 21 continuously and intermittently sucks and exhausts air to cool and remove dust from the computer main unit 10.
