Detailed Description

Example (b): the utility model provides a dust removal fan, includes shell 1 and flabellum 2, flabellum 2 can be pivoted install in shell 1, is formed with the blade 3 of a plurality of syntropy slopes on the 2 circumference lateral walls of flabellum, be formed with a dust removal hole 4 on the 1 lateral wall of shell, dust removal hole 4 can be with the inside and outside intercommunication of shell 1, still is equipped with deep bead 5 on the 1 lateral wall of shell, and deep bead 5 can open or seal dust removal hole 4.

When the fan runs normally, the wind shield 5 closes the dust removal hole 4, so that the air volume of the fan under the normal working condition is not reduced due to the increase of the dust removal function; when removing dust, make deep bead 5 break away from dust removal hole 4 and open dust removal hole 4, the dust that the fan anti-operation was stirred is blown down from dust removal hole 4 discharge fan under the reverse moving compressed air, realizes the self-cleaning of fan, avoids piling up the dust in the fan, is favorable to the fan to keep stable air output, improves its radiating effect.

The wind shield 5 is hinged to the side wall of the dust removal hole 4, and the wind shield 5 can rotate around a hinged shaft of the wind shield towards the inner side of the shell 1 by a set angle. Realize opening dust removal hole 4 or seal around articulated shaft 6 rotation through deep bead 5, when deep bead 5 rotates certain angle towards the fan is inside, dust removal hole 4 is opened, forms one through deep bead 5 and blocks guide structure, and it can block that the dust flows at fan housing 1 inner loop to lead the dust to dust removal hole 4, by the dust removal hole 4 discharge fan housing 1 outside.

A limit stop wall 7 is formed on the side wall of the inner side of the shell on one side of the dust removal hole 4, and can stop on the surface of one side wall of the wind shield 5 facing the inner side of the shell. Through spacing backstop wall 7 restriction deep bead 5 towards the inside pivoted angle of fan, when guaranteeing deep bead 5 to rotate extreme position towards the fan is inside, and have certain clearance B between the blade 3 of flabellum 2, avoid interfering the flabellum 2 rotation, simultaneously, it keeps certain opening angle, just can fully block that the interior dust of shell 1 flows to with dust direction dust removal hole 4.

An inclined plane is formed on the limit stop wall 7, and the inclined plane can be just flatly attached to the side wall of the wind shield 5. Through inclined plane and 5 flat contacts of deep bead, avoid the two to take place to block when deep bead 5 opens and put, the best forms the semicircle face at 5 articulated ends of deep bead, forms the cladding in the arc surface at 5 roots of deep bead at 7 roots of spacing backstop wall, and on deep bead 5 contacted gradually and flat inclined plane of pasting spacing backstop wall 7 at the pivoted in-process, form the striking with spacing backstop wall 7 when avoiding deep bead 5 to open, avoid producing the noise.

And a bulge part protruding from the side wall of the shell for a set distance is formed on one side wall of the wind shield 5 facing the inside of the shell. The fan rotates reversely, the protruding portion of the wind shield 5 enables the wind shield 5 to rotate a certain angle towards the inner side of the shell 1 under the blowing of compressed air, and the dust removing hole 4 is opened, so that the effect of automatically opening the dust removing hole 4 by the reverse rotation of the fan is achieved.

The deep bead 5 is towards the inside lateral wall of shell for and the outside lateral wall of shell has the inclined plane of contained angle, and this inclined plane is close to articulated shaft one end and can aligns the linking with the shell inside wall, and there is set distance A between the one end that the articulated shaft was kept away from on this inclined plane and the shell inside wall. Through the inclined plane setting of deep bead 5, make 5 tip thickness increases of deep bead, deep bead 5 is unanimous with 1 lateral wall thickness of shell towards articulated shaft one end thickness, when deep bead 5 closes, its this end aligns with 1 inboard of shell and links up, the deep bead 5 other end then protrusion is in the certain distance of 1 inside wall of shell, form a protruding structure, this structure is when the fan normal operating, can not cause the stopping to the fan air current, guarantee that the air flow is normal, when the fan removes dust, reverse air current can be opened deep bead 5 fast again.

And one end of the wind shield 5, which is far away from the hinged shaft, is contacted with the side wall of the dust removal hole 4 on the side wall of the shell 1 through an inclined plane. Wind shield 5 passes through the inclined plane contact with 4 lateral walls in dust removal hole, is favorable to guaranteeing wind shield 5 abundant closed dust removal hole 4, and the two can not take place the card simultaneously and put, through, wind shield 5 tip forms the inclined plane, and wind shield 5 tip forms closed angle structure 8 towards 1 inside one side of fan housing, and this structure is when removing dust, and high-pressure draught gets into and forms powerful thrust in the clearance between this closed angle structure and the 1 lateral wall of shell, opens wind shield 5 fast.

The device is also provided with a baffle driving device and a control module, the driving device can drive the wind shield 5 to move to close the dust removal hole 4 or separate from the dust removal hole 4, and the control module controls the driving device to work and the main shaft of the fan to rotate. The control module sets according to the preset condition, such as according to the running time of the fan, sets according to the rotating speed of the main shaft of the fan, sets according to the dust condition in the fan shell 1 and the like, controls the baffle driving device to run when the fan meets the set condition, opens the wind shield 5, realizes reverse rotation dust removal of the fan, completes dust removal after the fan reverses the set time, controls the baffle driving device to run reversely to close the wind shield 5, and informs the main shaft of the fan of normal rotation heat dissipation.

The driving device is a servo motor, and the servo motor drives the wind shield 5 to rotate. When the wind shield 5 is rotatably mounted on the housing 1, the servo motor drives the baffle to rotate, so as to open and close the dust removing hole 4, and of course, other driving modes can be adopted, such as a mode that the wind shield 5 slides back and forth, a mode that the wind shield vertically ascends and descends, and the like, so that the dust removing hole 4 can be closed and opened, and the structure is an equivalent alternative structure which can be easily thought by a person skilled in the art according to the patent.

A dust sensing device is also arranged in the fan housing 1 and is signaled to the control module. The dust induction device is used for inducing the dust accumulation condition in the shell 1, and then the baffle driving device is controlled to operate to realize automatic dust removal of the fan, meanwhile, the air baffle 5 is controlled to be closed to stop dust removal according to the dust removal condition in the shell 1, intelligent dust removal is realized by the structure, energy waste is avoided, and the dust induction device can be a sensor, an imaging device and the like.
