This scheme is used for dust collecting equipment of computer's principle to lie in:
and starting the motor, wherein the motor drives the piston to slide up and down in the negative pressure cavity in a reciprocating manner through the crank-slider mechanism. When the piston slides downwards, the piston compresses the second chamber, and the space of the first chamber is increased; the air in the second chamber will be exhausted through the second exhaust check valve and the first chamber will draw air in through the first intake check valve. Similarly, when the piston slides upwards, the piston compresses the first chamber, and the space of the second chamber is increased; the air in the first chamber will be exhausted through the first exhaust check valve and the second chamber will be drawn in through the second intake check valve. Because the first air inlet one-way valve and the second air inlet one-way valve are both communicated with the dust collection cavity, negative pressure is formed in the dust collection cavity; and because the dust removal disc is provided with the through holes, the dust suction cavity sucks dust through the through holes.
When the driving shaft reciprocates relative to the dust removing disc, the lower end of the driving shaft and the dust removing disc are provided with a spiral groove and a spiral rib which are matched with each other; therefore, in the process that the spiral rib and the spiral groove are mutually extruded, the dust removing disc rotates in a reciprocating mode relative to the dust removing cylinder, and the dust removing disc drives the hairbrush to rotate. When the brush is contacted with the computer mainboard, the brush can brush off dust, and the dust is sucked into the dust suction cavity by matching with the dust suction effect of the dust suction cavity.
The beneficial effect that this scheme produced is:
the motor drives the piston to slide in the negative pressure cavity in a reciprocating manner through the crank-slider mechanism, so that the dust suction cavity forms negative pressure to achieve the effect of dust suction; and when drive shaft reciprocating motion, the drive shaft still can drive dust removal dish reciprocating rotation, and the dust removal dish will drive the brush motion promptly, reaches the effect of cleaing away the dust on the computer mainboard, and cooperates the dust absorption effect in dust absorption chamber simultaneously, can more efficient clear away the dust, avoids the dust to adsorb on the computer mainboard once more.

The preferable scheme is three: as a further optimization of the second preferred scheme, a first sleeve and a second sleeve which are rotatably connected with the dust removing cylinder are arranged in the water cavity, the second sleeve is sleeved on the periphery of the first sleeve, a sliding sleeve which can only axially slide relative to the dust removing cylinder is sleeved on the periphery of the second sleeve, a spiral groove and a spiral rib which are matched with each other are arranged between the sliding sleeve and the second sleeve, and limiting ribs which are used for limiting the sliding sleeve and are fixed on the side wall of the water cavity are arranged on the upper side and the lower side of the sliding sleeve; all inlay magnet on sliding sleeve and the piston, first sleeve pipe and second sleeve pipe pass through one-way bearing and connect, still are equipped with in the water cavity and rotate the blade of being connected with a section of thick bamboo that removes dust, and the blade passes through torsional spring with first sleeve pipe and is connected, and is fixed with on the lid and carries out spacing gag lever post to the blade.
In the third preferred scheme, because the sliding sleeve and the piston are both inlaid with magnets, when the piston slides in a reciprocating manner in the vertical direction, the sliding sleeve can also slide in the water cavity in a reciprocating manner in the vertical direction due to the mutual attraction of the magnets. Because the spiral groove and the spiral rib which are matched with each other are arranged between the sliding sleeve and the second sleeve, when the sliding sleeve slides, the spiral groove and the spiral rib are extruded with each other, so that the second sleeve rotates in a reciprocating way. The second sleeve and the first sleeve are connected through the one-way bearing, so that the second sleeve can only drive the first sleeve to rotate in one direction; and the blade can not rotate under the limiting action of the limiting rod, so that the torsion spring for connecting the blade and the first sleeve can gradually store energy. After the completion removes dust, open the lid and will pull out the gag lever post simultaneously to the limiting displacement of restricted position pole no longer is driven the blade rotation by the blade, thereby the flow of water cavity water with higher speed avoids the dust to adsorb on the lateral wall in water cavity, is favorable to the dust to discharge out the water cavity.
The preferable scheme is four: as a further optimization of the preferred embodiment, the exhaust pipe is a corrugated pipe; thereby facilitating stretching and bending of the exhaust pipe.
