the fan comprises a fan main body, a fan body and a fan body, wherein the fan main body is provided with a fixing frame body and a positioning hole;

the filter screen is provided with filter holes and a drawing tongue for unloading;

the fan fixing piece is internally provided with a positioning column for positioning the fan main body and a fixing buckle for fixing the fan main body, the positioning column is arranged in the positioning hole, the fixing buckle is attached to the fixing frame body in an abutting mode, fixing plates which are arranged in an outward inclining mode are arranged on two sides of the fan fixing piece, and the lower end of each fixing plate is provided with a limiting buckle;

the fan fixing piece is fixed in the notch through a limiting buckle.

The utility model discloses an in this kind of prevent fan filtration fixed knot of flocculus structure, the filter screen is made for engineering plastics.

The utility model discloses an in this kind of prevent fan filter fixed knot of flocculus structure, the card muscle has on the fan mounting, the filter screen passes through the card muscle to be fixed in the fan main part.

The utility model discloses an in this kind of prevent fan filter fixed knot of flocculus structure, still have the protection muscle on the fan mounting.

Implement the utility model discloses a this kind of prevent fan filter fixed knot of flocculus constructs has following beneficial effect: this prevent fan of flocculus filters fixed knot and constructs novel in design, simple structure, the unable effective filtration flocculus that can be fine leads to the radiator to block up or the filter screen easily blocks up but the current situation of difficult clearance under the flocculus environment, and convenient realization fan main part's filter screen installation is cleared up with the dismantlement, does not rely on operating space and instrument to can realize fan main part's quick maintenance and change, maintain and clear up whole wind channel and also very easily realize.

For electrical product manufacturers, the overheating protection risk of the products caused by no filtering is reduced, and the communication cost with customers is reduced; the damage of the internal power device of the product caused by the blockage of the air channel in the floccule environment is reduced, the damage of the fan body caused by the floccule winding is also reduced, and the travel and material expenditure cost caused by field maintenance is reduced.

For an end user, the filtering is specially directed at a floccule field, so that the requirements of filtering floccules can be met, gaps among fins of a radiator are not blocked, the aim of easy cleaning is fulfilled, a filter screen is not easy to block, and the aim of prolonging the maintenance period is fulfilled. In addition, due to the fact that the air channel is easy to maintain and can be cleaned easily, the operability and efficiency of maintenance are greatly improved in practical use, the equipment shutdown maintenance time caused by the risk of reporting the overheating fault or the shutdown maintenance time caused by equipment damage is reduced, and manpower and material resources are greatly saved.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 10, the utility model discloses a this kind of prevent fan filter fixed knot of flocculus constructs, include:

the fan main body 10 is provided with a fixing frame body 11 and a positioning hole 12 on the fan main body 10.

A filter screen 13, the filter screen 13 is provided with a filter hole 14 and a drawing tongue 15 for unloading. The size of the opening of the filter hole 14 is larger than that of a common fan filter screen, so that air can be conveniently fed.

The extraction tongue 15 is used for facilitating the extraction tongue 15 to be taken down when being maintained and cleaned, and the filter screen 13 is made of engineering plastics, has good elastic performance and can be more conveniently installed on the fan fixing piece 16.

The fan fixing piece 16, the fan main body 10 is installed in the middle of the fan fixing piece 16, the inside of the fan fixing piece 16 is provided with a positioning column 17 for positioning the fan main body 10 and a fixing buckle 18 for fixing the fan main body 10, the positioning column 17 is arranged in the positioning hole 12, and the fixing buckle 18 is attached to the fixing frame 11 and used for limiting the fixing frame 11.
