Description

Fan guard releasing dirt is flapped device

Technical field

Flap device the present invention relates to a kind of fan guard releasing dirt, fan in front of fan can be removed in a manner of persistently flapping Dust, the cotton-wool that each ventilation opening inner wall is attached on cover remain each ventilation opening of the fan guard and do not attach, block dust The unobstructed state of cotton-wool, to ensure that running air supply efficiency more particularly to the fan guard releasing dirt of fan are flapped the fan of device Ontology, fan guard, soft flap part and drive module.

Background technique

It using fan rotation, operates to drive air externally to blow or guide the fan structure of air-flow, has been existing skill. This kind of fan structure includes the various electric fan to dry people, also includes computer fan, air-conditioning fan, industrial equipment Wind-guiding fan and extraction fan, be typically provided with fan guard in front of existing fan structure, touched to block personnel or article Fan in rotational run, to prevent the situation of causing danger.

Existing fan guard is usually to be constituted with metal net mask, and wind caused by the fan running is made to pass through the metal net mask On ventilation opening externally send out；In order to control the air supply direction of the fan, existing fan guard may be made as wind-guiding dish-type State enables the ventilation opening on the guide disc to change, guide the air supply direction of the fan at any time.

But the dust, cotton-wool or other pollutants in environment are easy to attach, accumulate the fan guard in front of existing fan The inside and outside wall surface of ventilation opening be easy to cause dust, cotton-wool to be covered with, that block the fan guard each is logical after the fan operates for a long time The situation in air port seriously affects the running air supply efficiency of the fan.

In view of this, the present inventor is the research and practical experience for accumulating many years related fields, spy creates a kind of wind Fan cover releasing dirt is flapped device, so as to improving the defect of the above-mentioned prior art.

Summary of the invention

Therefore, the main object of the present invention is to provide a kind of fan guard releasing dirt and flaps device, comprising: a fan sheet Body, inside are equipped with a fan；One fan guard configures in front of the fan body, which has one towards the fan body Outer end face other than front and one towards the fan inner face, multiple ventilation openings are equipped between the outer end face and inner face； Multiple soft parts of flapping configure between the fan guard inner face and fan, so that the soft part of flapping is respectively by the fan Cover inner face protrudes into each ventilation opening；And a drive module, combine the fan guard and soft part of flapping one of wherein, The drive module can drive the fan guard to move relative to each other with soft part of flapping, and move into the soft part of flapping one by one And remove each ventilation opening.

By above-mentioned, during fan running air-supply, removed in a manner of persistently flapping using the soft part of flapping Dust, the cotton-wool that each ventilation opening inner wall is attached remain each ventilation opening of the fan guard and do not attach, block dust cotton-wool Unobstructed state, keep the fan air-supply smooth and changed by each ventilation opening of the fan guard with ensuring the running air supply efficiency of fan It is apt to ventilation opening in front of existing fan and is easy the defect for attaching, accumulating dust cotton-wool and influencing to operate air supply efficiency.

According to above-mentioned key structural feature, which includes a motor, and it is corresponding to be equipped with one in front of the fan body The opening of the fan, the motor are set by the support of multiple brackets and are fixed on the open center, extend the bracket by the open center To the open circumferential, the soft part of flapping is fixed on the bracket along the extending direction arrangement of the bracket, and the motor Shaft combines fan guard center, enables the motor that the fan guard to be driven to rotate, while promoting the soft bat on the bracket Moving part moves in and out each ventilation opening.

Alternatively, the drive module include an axis body and at least one from the axis body toward the axis body around radial prolong The arm stretched, the axis body are hubbed between the fan guard inner face and fan, it is described it is soft flap part along the arm extension Direction arrangement is fixed on the arm, which can be axle center in the neighbouring fan guard using the fan guard center with the arm It is rotated at inner face, while the soft part of flapping on the arm being promoted to move in and out each ventilation opening.Wherein, the fan The opening of a corresponding fan is equipped in front of ontology, which configures a motor, and the shaft of the motor can drive the wind Fan cover rotation, the axis body have an axis hole, are set in the axis body in the shaft of the motor by axis hole and rotate, which is equipped with Multiple, each arm is placed in the axis hole two sides, and each arm is set as propeller kenel, and the wind-force that can receive the fan is blown It is dynamic, to drive the axis body and arm to rotate；Alternatively, the drive module includes a rot, which can drive institute State axis body and arm rotation.

According to above-mentioned key structural feature, the soft part of flapping be set as hairy, strip, sheet and it is band-like at least within A kind of structure kenel, the soft part of flapping is from the fan guard center toward the fan guard peripheral direction sequential.

According to above-mentioned key structural feature, which is set as one kind at least within of fabric, flexible glue and fiber Soft part of flapping.
