Abstract

The utility model discloses a fluid pusher which comprises an electric motor and a liquid pushing part. The electric motor at least comprises a stator and a rotor, a rotating shaft of the rotor is a hollow shaft, in which fluid can pass in and out, and the fluid pushing part is fixedly installed inside the hollow shaft. In the fluid pusher, the fluid pushing part (as a turbine or an impeller) is fixedly installed inside the hollow shaft of the electric motor, the hollow rotating shaft forms a fluid access passage, when the hollow rotating shaft of the electric rotates, the fluid pushing part inside the hollow rotating shaft is rotated along with the hollow rotating shaft to further push the fluid to flow with high effect, obviously the fluid pusher can realize perfect combination of the electric motor and the fluid pushing part, thereby reducing total size of the whole equipment, and further reducing fluid resistance while combining with devices such as the turbine, the impeller and the like, and increasing fluid quality.

Description

Fluid promotes machine

Technical field

The utility model relates to a kind of equipment that fluid high-effectives such as gas, liquid flow that is used to promote.

Background technique

Range hood, fan, this kind equipment of water pump mainly are used for promoting fluids such as gas, liquid and flow.This kind equipment is made up of with fluid driving members such as the turbine that is installed in the motor outside, impellers the motor of solid spindle usually in the prior art.In this case, because that motor and fluid promote combining of equipment is more open, shortcoming such as have that volume is big, vibrations are big, noise is high or promotion efficient is low.

The model utility content

The purpose of this utility model is to provide the fluid that a kind of volume is little, promotion efficient is high to promote machine.

The utility model fluid promotes machine, comprises motor and fluid driving member, and described motor comprises a stator and a rotor at least, and the rotating shaft of rotor be for passing in and out the quill shaft of fluid, and described fluid driving member is fixedly mounted in the quill shaft.

Described fluid driving member is turbine or impeller.

The quill shaft of each rotor of described motor is ganged up.

Each stator of described motor is corresponding one by one with each rotor.

Corresponding at least two rotors of stator of described motor.

The utility model is fixedly mounted on fluid driving member (as turbine, impeller) in the hollow axle of motor, hollow axle forms fluid turnover path, when the hollow axle of motor rotates, its inner fluid driving member is followed rotation, and then propelling fluid high efficiency flow, obviously therefore, the utility model can be realized the perfect adaptation of motor and fluid driving member, reduce the size of total equipment, when especially combining with equipment such as turbine, impellers, can further reduce fluid resistance, improve liquid flux.

Description of drawings

Fig. 1 is the structural representation of first kind of mode of execution of the present utility model.

The structural representation of second kind of mode of execution of Fig. 2

Fig. 3 is the structural representation of the third mode of execution.

Embodiment

Mode of execution one:

The structure that has reflected the utility model mode of execution one from Fig. 1, it also is a structure the most basic of the present utility model, as can be seen from the figure the utility model fluid promotion machine still has motor 1 and fluid driving member 2, wherein motor has only a stator 11 and a rotor 12, the rotating shaft of rotor 12 is to pass in and out the quill shaft of fluid 13, fluid driving member 2 is fixedly mounted in the quill shaft 13, and fluid driving member 2 adopts impeller.This mode of execution can be used as axial-flow blower or fan.

Mode of execution two: referring to Fig. 2

Fig. 2 has reflected the structure of the utility model mode of execution two.Present embodiment has two or more stators 11 and rotor 12 as can be seen from Figure 2, and stator and rotor are corresponding one by one, the rotating shaft of rotor 12 equally remains quill shaft 13 with mode of execution one, and all be fixed with fluid driving member 2 (as turbine or impeller) in each quill shaft, each quill shaft is together in series (can connect with bearing 14), forms the fluid access way 15 of an integral body.Present embodiment can be used as water pump, also can be used as range hood, it can increase promotion power, simultaneously, suitably arrange the angle of each internal rotor blade and axis, and rotor is prolonged clockwise the sense of rotation (changeing some rotor counterclockwise rotations as some rotors clockwise) of setting rotor and the vibrations that counterclockwise produce are offset, and effectively reduces the equipment operation noise.

Mode of execution three: referring to Fig. 3

Fig. 3 has reflected the structure of the utility model three.As can be seen from Figure 3 in stator 11 of present embodiment some rotors 12 are arranged, the rotating shaft of these rotors 12 remains quill shaft 13, quill shaft 13 still has fluid driving member 2 (impeller or turbine etc.), and still series connection forms a fluid passage 15 between each quill shaft.Present embodiment also has the advantage that structure is compact more, running noise is littler except that the advantage with mode of execution two, present embodiment especially is suitable as range hood.
