The motor is at the operation in-process, when inhaling the air current through suction hole 6, filter the dust in the air current through filter screen 1303, can avoid the dust to enter into organism 1 inside, meanwhile, the motor shaft can drive the lantern ring 1307 through pivot front end 1310 and carry out synchronous rotation, because first slider 1305 can slide in the first spout 1304 of the solid fixed ring 1302 of second, the lantern ring 1307 can drive linkage piece 1306 on first slider 1305 through gangbar 1308 and carry out the circular orbit motion at rotatory in-process, thereby let linkage piece 1306 can drive cleaning plate 1309 and clean the dust that filter screen 1303 surperficial blocked, can ensure that ventilating of filter screen 1303 can not receive the influence of dust.
When the motor operates, the motor shaft drives the first rotary disc 4 to drive the heat dissipation fan blades 5 to operate, the first rotary disc 4 can drive the second rotary disc 10 to synchronously rotate through the transmission shaft 9, at the moment, the second slide block 1402 can operate by utilizing centrifugal force in the rotating process of the second rotary disc 10, because the second slide block 1402 can slide in the second sliding groove 1401, therefore, under the centrifugal force, the second slide block 1402 can stretch the connecting spring 1403 to drive the connecting plate 1404 to move outwards, so that the connecting plate 1404 compresses the first windshield 1405, the air outlet area of the air outlet hole 12 is increased, the quick discharge of hot air in the machine body 1 is facilitated, and the operating power according to the motor is different, at the moment, the connecting plate 1404 compresses the first windshield 1405 under the centrifugal action to different degrees, and the automatic adjustment of the air outlet area of the air outlet hole 12 is facilitated according to the heat dissipation requirement of the motor.
When the connecting plate 1404 moves outwards, the driving rod 1406 can drive the squeezing plate 1407 to move synchronously, so that the squeezing plate 1407 can squeeze the pressurizing air bag 1409, when the pressurizing air bag 1409 is squeezed by the squeezing plate 1407, the gas in the pressurizing air bag 1409 can enter the air cavity 1501 of the first fixing ring 1301 through the connecting pipe 1505, the pneumatic telescopic rod 1502 can be driven to move along with the increase of the air pressure in the air cavity 1501, the pneumatic telescopic rod 1502 can drive the moving plate to move downwards, the moving plate 1503 can compress the second air blocking cover 1504, the air inflow of the air suction holes 6 is increased, and the pneumatic telescopic rod 1502 can control the moving distance of the moving plate 1503 to be equal to the moving distance of the connecting plate 1404 according to the change of the air pressure in the air cavity 1501, so that the air suction holes 6 can be correspondingly adjusted according to the adjustment of the air outlet holes 12, the air inflow of the air suction holes 6 is equal to the air outlet amount of the air outlet holes 12, the flow rate of the cooling air flow at the 1 can be increased, and the cooling effect in the machine body 1 can be improved.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
