Abstract
The utility model belongs to the technical field of machineries, and particularly relates to a cross-flow fan. Due to the protection purpose, the existing fan is provided with an outer cover, while the outer cover is only installed outside an impeller of the cross-flow fan without consideration that the outer cover installed randomly reduces the blast capacity of the fan and brings loud noise, so that the work efficiency of the cross-flow fan is lowered. The cross-flow fan comprises a motor installed at one side of a shell, wherein the shell is internally provided with the impeller driven by the motor; and the cross-flow fan is characterized in that the outer cover is fixed and screwed on the shell and is provided with rhombic vent holes, and the angle of the vent holes is in accordance with the wind direction of the impeller. Under the premise of protecting the normal work of the cross-flow fan, the cross-flow fan has large blast capacity and low noise and the work efficiency of the motor is improved.
Description
Technical field
The utility model belongs to field of mechanical technique, refers in particular to a kind of cross flow fan.
Background technique
Existing cross flow fan is outside or be provided with an outer cover, or directly allows impeller outside exposed.And be not provided with the cross flow fan of outer cover, and existing certain potential safety hazard, near the foreign object cross flow fan is easily gone by the impeller inspiration, thereby causes the damage of blower fan, and exposed impeller also easily damages the staff; In addition, the existing blower fan that outer cover has been installed is owing to being the purpose that is in protection; only at the impeller outer of cross flow fan, outer cover to be installed; but do not consider that outer cover of careless installation can reduce the air output of blower fan, and bring larger noise, thereby reduced the working efficiency of cross flow fan.
The model utility content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and it is a kind of simple in structure that the spy provides, and simultaneously, can ensure the cross flow fan of larger air output and low noise.
Two, technological scheme
For solving the problems of the technologies described above, the utility model cross flow fan, include the motor that is arranged on housing one side, above-mentioned enclosure interior arranges an impeller by the motor driving, wherein, also be bolted and fixed with outer cover on above-mentioned housing, this outer cover is provided with the vent hole of rhombus, the angle of above-mentioned vent hole with the air-out of impeller to consistent.
As optimization, above-mentioned vent hole transverse distribution is on outer cover.
Three, the beneficial effects of the utility model
Under the prerequisite of protection cross flow fan normal operation, can guarantee the working efficiency that cross flow fan has larger air output, low noise and improves motor.
Description of drawings
Fig. 1 is the perspective view of the utility model cross flow fan.
In figure, 1 is housing, and 2 is impeller, and 3 is motor, and 4 is outer cover, and 5 is vent hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model cross flow fan is described further:
Mode of execution one: as shown in Figure 1, the utility model cross flow fan, include the motor 3 that is arranged on housing 1 one sides, above-mentioned housing 1 inside arranges an impeller 2 by motor 3 drivings, wherein, also be bolted and fixed with outer cover 4 on above-mentioned housing 1, this outer cover 4 is provided with the vent hole 5 of rhombus, and the air-out of the angle of above-mentioned vent hole 5 and impeller 2 is to consistent; Above-mentioned vent hole 5 transverse distribution are on outer cover 4, that is, the diagonal that the vent hole 5 of rhombus is grown is parallel with the axis of impeller 2, and the size of rhombus vent hole 5 is determined by the size of motor 3 power and the size of impeller 2, and concrete large I is determined according to actual conditions.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. cross flow fan, include the motor that is arranged on housing one side, described enclosure interior arranges an impeller by the motor driving, it is characterized in that: also be bolted and fixed with outer cover on described housing, this outer cover is provided with the vent hole of rhombus, the angle of described vent hole with the air-out of impeller to consistent.
