Abstract
The invention discloses a small-sized impeller for air suction of small and medium-sized direct current motors. The small-sized impeller comprises a hollow body. A through hole is formed in the center position of the body. An air duct is distributed around the through hole anticlockwise. According to the technical scheme, the angle of a product is adjusted according to the motion direction of an airflow inlet portion, the radian of the air duct is designed reasonably, thus, reasonableness is higher during acceleration of air, then the suction force is improved, and the service life of a battery is prolonged; and meanwhile, the time of application of electric energy is shortened, so that the energy saving effect is achieved.
Description
Technical field
The present invention relates to the technical field of movable vane wheel, more particularly, to a kind of small-sized moving of middle-size and small-size direct current generator air draught
Impeller.
Background technology
Existing hand held cleaner or hair-dryer, are usually used dry cell and are powered, due to DC micro-motor band
Dynamic to rotate at a high speed, air produces under the influence of centrifugal force blast, so as to realize the blowing function of dust catcher function and hair-dryer,
The defect for so producing is that suction is low, and the use time of dry cell is short.
The content of the invention
Present invention aim to address problem set forth above, there is provided a kind of simple structure, reduce noise it is a kind of medium and small
The small-sized moving impeller of type direct current generator air draught.
The purpose of the present invention is realized as follows：A kind of small-sized moving impeller of middle-size and small-size direct current generator air draught,
With hollow body, the body central position is provided with through hole, and the through hole surrounding is distributed with air channel counterclockwise.
The small-sized moving impeller of above-mentioned a kind of middle-size and small-size direct current generator air draught, the air inlet in the air channel is provided with wedge angle
Piece.
The small-sized moving impeller of above-mentioned a kind of middle-size and small-size direct current generator air draught, the cross section in the air channel is air channel arc road
It is consistent with air channel curvature.
Advantages of the present invention：Technical scheme adjusts the angle of product according to the direction of motion in air flow inlet portion,
Rational design exhaust passage arc road so that air more rationally, so as to increase suction, increased battery and use in accelerator
Time, while reducing the time of electric energy, the effect of energy-conservation is reached.
Description of the drawings
In order that present disclosure is easier to be clearly understood, below according to specific embodiment and accompanying drawing is combined, it is right
The present invention is described in further detail, wherein
Fig. 1 is the structural representation of the present invention.
Reference：1st, body, 2, through hole, 3, air channel, 4, wedge angle piece, 5, air channel arc road.
Specific embodiment：
As shown in Figure 1, a kind of small-sized moving impeller of middle-size and small-size direct current generator air draught, with hollow body 1, the body
91 centres are provided with through hole 2, and the surrounding of the through hole 2 is distributed with air channel 3 counterclockwise.The air inlet in the air channel 3 is provided with
Wedge angle piece 4.The cross section in the air channel 3 is that air channel arc road 5 is consistent with air channel curvature.
Particular embodiments described above, has been carried out further in detail to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail it is bright, should be understood that the foregoing is only the present invention specific embodiment, be not limited to the present invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., should be included in the guarantor of the present invention
Within the scope of shield.
