Description
Technical field
The utility model relates to a kind of blower fan, particularly relates to a kind of pipeline fan.
Background technique
The air output that axial-flow blower is had by it is large, and the simple outstanding advantages of structure obtains application at wide spectrum.But it enters air draft direction in the same way, air duct is limited as the shortcoming also outstanding application expansion that govern axial-flow blower of round structure and electric machine inconvenient maintenance in air duct.Motor due to axial-flow blower is placed in logical air-supply pipeline, not only can increase the windage in pipe-line system, affect the flow velocity of fed sheet of a media in pipeline, while the axial-flow blower function that do not purify air.Therefore, for solving the problem, spy provides a kind of new technological scheme.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of pipeline fan.
The utility model is achieved through the following technical solutions:
A kind of pipeline fan; comprise support, fan air drum; described fan air drum inside is provided with motor; the output shaft end of described motor is connected with fan blade; the side that described fan air drum is positioned at motor back is provided with air intake safety cover; state air intake safety cover and be provided with thin-wall conical air guide sleeve near the middle part of a side surface of motor; annular air purifying net is provided with between described air intake safety cover and motor; the lower end of described fan air drum is provided with negative ion generator, and described negative ion generator is connected with air-purifying net function.
As preferably, the opening diameter of a circle of described air guide sleeve is greater than the diameter of motor.
As preferably, described air-purifying net is netted.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the back of motor covers by arranging thin-wall conical air guide sleeve by the utility model, greatly can reduce motor like this to distinguished and admirable resistance, and negative ion generator and air-purifying net, can realize purifying air.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. support; 2. fan air drum; 3. motor; 4. fan blade; 5. air intake safety cover; 6. air guide sleeve; 7. negative ion generator; 8. air-purifying net.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of pipeline fan, comprise support 1, fan air drum 2, described fan air drum 2 inside is provided with motor 3, the output shaft end of described motor 3 is connected with fan blade 4, the side that described fan air drum 2 is positioned at motor 3 back is provided with air intake safety cover 5, described air intake safety cover 5 is provided with thin-wall conical air guide sleeve 6 near the middle part of a side surface of motor 3, the opening diameter of a circle of described air guide sleeve 6 is greater than the diameter of motor 3, and this air guide sleeve 6 is one-body molded with air intake safety cover 5, be convenient to install, the back of motor 3 can cover by air guide sleeve 6 simultaneously, greatly can reduce motor 3 like this to distinguished and admirable resistance, reduce the power consumption of blower fan, annular air purifying net 8 is provided with between described air intake safety cover 5 and motor 3, the lower end of described fan air drum 2 is provided with negative ion generator 7, described negative ion generator 7 is connected with air-purifying net 8 function, described air-purifying net 8 is in netted, negative ion generator 7 and air-purifying net 8 can realize purifying air, and when the impurity that air-purifying net 8 adsorption is more, cleaning can be dismantled.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
