Abstract
The utility model discloses a thin type dust-free fan which structurally comprises a main body. A cover plate is arranged on an air inlet of the main body, an air guiding ring is fixed in the middle of the cover plate, handles are arranged on the two sides of the cover plate, a motor base is arranged inside the main body, a motor is fixed on the motor base, an impeller is fixed on the motor, an internally-installed stator is arranged on the motor, an externally-installed rotor is arranged on the outer side of the internally-installed stator, the impeller is fixed on the externally-installed rotor, air deflecting plates are perpendicularly arranged below the impeller, a circular groove is formed in the center of the impeller, the motor is arranged in the circular groove, and a conical flow guiding cavity is formed in the top of the impeller. According to the thin type dust-free fan, the defects in the prior art can be overcome, the internal structure of the dust-free fan is reasonably designed, the thickness of the dust-free fan is reduced on the premise that the air volume is not influenced, and the application environment of the dust-free fan is expanded.
Description
Technical field
The utility model relates to a kind of ventilation plant, especially a kind of slim Dustless air feeder.
Background technique
Existing Dustless air feeder is due to highly higher, narrower and small in some spaces, insufficient height, or have and install more difficultly in the environment of pipeline, limited the use of Dustless air feeder.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of slim Dustless air feeder, can improve the deficiencies in the prior art, internal structure by the appropriate design Dustless air feeder, reduce the thickness of Dustless air feeder under the prerequisite that does not affect air output, expanded the suitable environment of Dustless air feeder.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of slim Dustless air feeder, structure comprises main body, the intake grill of main body is provided with cover plate, in the middle of cover plate, is fixed with air-ducting ring, and the both sides of cover plate are provided with handle, be provided with motor base in main body, be fixed with motor on motor base, be fixed with impeller on motor, described motor is provided with built-in stator, built-in stator arranged outside has outboard rotor, and described impeller is fixed on outboard rotor; Be vertically installed with current plate below described impeller; The center of described impeller is provided with circular groove, and described motor is arranged in circular groove; The top of described impeller is provided with the conical flow guiding chamber.
As preferably, on described air-ducting ring, be provided with protective net.
As preferably, the sidewall of described main body is provided with controller.
The beneficial effect that adopts technique scheme to bring is: the motor in the utility model adopts built-in stator and outboard rotor, can reduce the axial dimension of motor, and then reduces the thickness of blower fan.The exhaust air rate of impeller can be improved in current plate and conical flow guiding chamber, makes under the prerequisite that does not reduce fan delivery, can reduce the thickness of impeller.The circular groove at impeller center is used for installing motor, can reduce motor taking up room in blower fan, reduces blower fan thickness.Protective net is for preventing that foreign matter from entering blower fan.The controller of blower fan is arranged on the side of main body, has reduced the space hold of vertical direction.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of an embodiment of the utility model.
In figure: 1, main body; 2, cover plate; 3, air-ducting ring; 4, motor base; 5, motor; 6, impeller; 7, built-in stator; 8, outboard rotor; 9, current plate; 10, circular groove; 11, conical flow guiding chamber; 12, handle; 13, protective net; 14, controller.
Embodiment
With reference to Fig. 1, structure of the present utility model comprises main body 1, the intake grill of main body 1 is provided with cover plate 2, in the middle of cover plate 2, is fixed with air-ducting ring 3, and the both sides of cover plate 2 are provided with handle 12, be provided with motor base 4 in main body 1, be fixed with motor 5 on motor base 4, be fixed with impeller 6 on motor 5, described motor 5 is provided with built-in stator 7, built-in stator 7 arranged outside have outboard rotor 8, and described impeller 6 is fixed on outboard rotor 8; Be vertically installed with current plate 9 below described impeller 6; The center of described impeller 6 is provided with circular groove 10, and described motor 5 is arranged in circular groove 10; The top of described impeller 6 is provided with conical flow guiding chamber 11.
It should be noted that on described air-ducting ring 3 and be provided with protective net 13.
In addition, the sidewall of described main body 1 is provided with controller 14.
Working principle of the present utility model is: the motor 5 in the utility model adopts built-in stator 7 and outboard rotor 8, can reduce the axial dimension of motor 5, and then reduce the thickness of blower fan.The exhaust air rate of impeller 6 can be improved in current plate 9 and conical flow guiding chamber 11, makes under the prerequisite that does not reduce fan delivery, can reduce the thickness of impeller 6.The circular groove 10 at impeller 6 centers is used for installing motor 5, can reduce motor 5 taking up room in blower fan, reduces blower fan thickness.Protective net 13 enters blower fan for preventing foreign matter.The controller 14 of blower fan is arranged on the side of main body 1, has reduced the space hold of vertical direction.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
