Description
Technical field
A kind of air exhausting device is the utility model is related to, is especially a kind of blower fan.
Background technology
Problems with use often be present in the blower fan of prior art：
1st, blower fan more or less can all produce vibrations in the course of the work, for industrial blower fan, typically
Because power is larger and volume is more huge, cross flow medium impact under shake it is particularly evident, vibrations can both bring it is larger
Noise, the service life of blower fan is had a strong impact on again；
2nd, blower fan wind wheel is inconvenient to clean after enclosure is installed to；
3rd, blower interior oil smoke is not filtered when being discharged, and ventilation shaft is oiled, and smoke stratification needs are long-term to be cleaned, clearly
Wash more troublesome.
The content of the invention
In view of the defects of above-mentioned prior art, the purpose of this utility model is：A kind of blower fan is provided, good muffling effect,
Wind wheel is easy to clean and blower interior had filtering fume function.
Technical solution of the present utility model is：Blower fan, including shell and the wind wheel that is arranged in shell, wind wheel connect
Ventilation duct is connected to, ventilation duct bottom has ventilating opening, and the back of the shell is provided with a door-plate, and one end and the shell of the door-plate are carried on the back
Portion is rotatably connected, and the back fixation of the door-plate has a support, and the top of the support is provided with a motor, and the rotating shaft of motor is worn
It is connected after crossing door-plate with wind wheel, and wind wheel is fixed on the inside of door-plate；The outer casing inner wall is provided with silencing cotton and noise reduction mesh plate；
The ventilation duct top is provided with screen pack orifice plate.
Further, one end of the door-plate is hinged by two hinges with case back.
Further, the noise reduction mesh plate is located on the inside of silencing cotton.
Using blower fan provided by the utility model, its advantage is：
1st, enclosure has silencing cotton and noise reduction mesh plate, can greatly reduce noise；
2nd, wind wheel is fixed on the inside of door-plate, and one end and the case back of door-plate are hinged, so door-plate is turned an angle
Afterwards, wind wheel can just stretch out shell, thus facilitate cleaning wind wheel, moreover, after motor is exposed at enclosure, it is ensured that
Oil smoke will not enter in motor bearings, ensure that the service life of motor；
3rd, ventilation duct top is provided with screen pack orifice plate, and screen pack orifice plate will be arranged by ventilation duct again after filtering oil smoke one time
Go out, with regard to the covering of oil smoke layer can be reduced in pipe surface of so divulging information, so as to reduce the cleaning frequency of ventilation duct.
Brief description of the drawings
Fig. 1 is schematic front view of the present utility model；
Fig. 2 is left view schematic diagram of the present utility model；
Fig. 3 is enclosure structural representation.
Shown in figure：1-shell, 2-wind wheel, 3-ventilation duct, 31-ventilating opening, 4-door-plate, 5-support, 6-electricity
Machine, 7-silencing cotton, 8-noise reduction mesh plate, 9-hinge, 10-screen pack orifice plate.
Embodiment
For it is relatively directly perceived, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model accompanying drawing
Nonrestrictive feature description is as follows：
As shown in Fig. 1-Fig. 3, blower fan, including shell 1 and the wind wheel 2 that is arranged in shell 1, wind wheel 2 are connected with ventilation
Pipe 3, the bottom of ventilation duct 3 have ventilating opening 31, and the back of shell 1 is provided with a door-plate 4, and one end and the back of shell 1 of the door-plate 4 can
Rotation connection, the back fixation of door-plate 4 have a support 5, and the top of support 5 is provided with a motor 6, and the rotating shaft of motor 6 passes through door-plate 4
It is connected afterwards with wind wheel 2, and wind wheel 2 is fixed on the inner side of door-plate 4；The inwall of shell 1 is provided with silencing cotton 7 and noise reduction mesh plate 8, noise reduction
Mesh plate 8 is located at the inner side of silencing cotton 7；The top of ventilation duct 3 is provided with screen pack orifice plate 10.
Rotated in order to facilitate door-plate 4, one end of door-plate 4 is hinged by two hinges 9 and the back of shell 1.
Blower fan provided by the utility model, there are silencing cotton 7 and noise reduction mesh plate 8 inside shell 1, can greatly reduce
Noise；Wind wheel 2 is fixed on the inner side of door-plate 4, and one end and the back of shell 1 of door-plate 4 are hinged, so door-plate 4 is turned an angle
Afterwards, wind wheel 2 can just stretch out shell 1, thus facilitate cleaning wind wheel 2, moreover, after motor 6 is exposed at the outside of shell 1, can
To ensure that oil smoke will not enter in the bearing of motor 6, the service life of motor 6 ensure that；The top of ventilation duct 3 is provided with screen pack orifice plate
10, screen pack orifice plate 10 will be discharged by ventilation duct 3 again after filtering oil smoke one time, and just oil can be reduced on such surface of ventilation duct 3
The covering of smoke stratification, so as to reduce the cleaning frequency of ventilation duct 3.
Certainly, it these are only preferred embodiment of the present utility model, it is non-therefore limit to patent of the present utility model
Scope, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, all should similarly wrap
It is contained within scope of patent protection of the present utility model.
