Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in combination with specific implementation methods and accompanying drawings.

As shown in Fig. 1 and Fig. 2, this novel wind guiding device filter unit has the casing 8 of flat cuboid shape; The air of the fan is initially filtered to remove dust impurities; the air inlet 10 is provided with an air inlet pipe (not shown) outside to facilitate air entering the casing 8; the inside of the casing 8 has an air duct 9; the lower surface of the casing 8 An air outlet 12 is provided, and a high-efficiency filter 16 is arranged inside the air outlet 12, and the high-efficiency filter 16 performs high-efficiency filtration on the discharged air again. A fan 22 is arranged inside the casing 8 for sucking and exhausting air. The outside of the casing 8 is provided with a handle 18, which is convenient for moving and installing the novel air guiding device filter unit. The outside of the casing 8 also has a control box 20 through which the operator controls the work of the new air guiding device filtering unit.

As shown in FIG. 1 , the fan 22 includes a motor 24 and an impeller 26 , and the impeller 26 is detachably sleeved on the transmission shaft of the motor 24 . The impeller 26 and the motor 24 are arranged separately, so that the impeller can match various motors.

The utility model greatly improves the traditional fan impeller, and the structure of the improved impeller 26 is shown in Fig. 3 and Fig. 4 . FIG. 3 is a top view of the impeller 26 , and FIG. 4 is a right side view of the impeller 26 . As shown in FIGS. 3 and 4 , the impeller 26 includes a bottom cover 3 and several blades 1 mounted on the bottom cover 3 , and there may be seven blades 1 . Wherein, it can be seen from FIG. 4 that the bottom cover 3 is recessed inward, and the height of the bottom cover 3 recessed inward is 50%-70% of the overall height of the impeller 26 . The impeller 26 is of rear wing type, that is, the arc shape of the blade 1 is opposite to the direction of rotation of the impeller 26 when it works. As shown in FIG. 3 , the impeller 26 rotates counterclockwise during operation, while the arc of each blade 1 of the impeller 26 is clockwise. Because the impeller 26 of the utility model adopts a center recessed structure, the overall height of the fan after the motor is installed is effectively reduced, and the specific volume is small. At the same time, the rear wing structure of the blade 1 can effectively reduce the vibration of the fan, reduce the noise of the fan, and increase the wind pressure and air volume at the same time.

Fig. 5 is a structural view of the air guide channel of the filter unit of the new air guide device according to the embodiment of the present invention. As shown in FIG. 3 , the air guiding channel 9 has an arc-shaped edge 9 a, and the arc-shaped edge 9 a cuts 1/3 of the height of the impeller 26 . This kind of air duct can reduce noise, increase wind speed, reduce air volume loss, and expand the application range of the new air guiding device filter unit.

When the novel air guiding device filter unit of the present embodiment is working, the fresh air from the outside is initially filtered by the grid 14, then enters the blower fan 22 through the air inlet 10, is filtered by the high-efficiency filter 16, and is sent in by the air outlet 12. In the working area, air purification is guaranteed by double filtration. The fan 22, especially the special shape design of the impeller 26, and the structure of the air guiding channel 9 make the air supply effect of the new air guiding device filter unit of the present utility model good, the operation noise is low, the volume is small, and the space is saved.

The filter unit of the new wind guide device of the utility model has high working efficiency, strong purification ability, small casing, convenient installation, simple structure, modular design, and is suitable for industrial standardized production; it has a wide range of uses.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
