Abstract

The utility model relates to an electric fan. An adjustable speed motor is installed on a permanent seat. The electric fan is characterized in that a main shaft of the motor is sequentially connected with a turbine blade group and an inducer, and short sleeves are connected among each layer impellers; a long sleeve is connected between the turbine blade group and the inducer; airflow splitters are evenly distributed on the inducer; a fan gas hood is a cavity integrally, the top of the cavity is connected with the permanent seat through tightening bolts, the upper part of the cavity is provided with an annular air inlet filter fence, and the inside of the fence is connected with an air filter screen; the middle part and the lower part of the cavity are in closes states, the appearance of the lower part is shrunk firstly and then expanded, and the bottom is provided with an air outlet; and the number of airflow splitters on the inducer is equal to that of the blades distributed on each layer of impellers. The utility model blows out air through the rotating inducer along the circumference after the air is compressed, can meet the requirement that people in different directions need blowing simultaneously, improves the mechanical efficiency, reduces the noise and enables the human body to feel more comfortable.

Description

A kind of electric fan
Technical field
The utility model relates to a kind of electric fan, is specifically related to a kind of electric fan that diverse location is dried simultaneously of not realizing by shaking the head.
Background technique
The present oscillating ceiling fan that uses of people, what have is installed in ceiling, and what have is installed in side wall, though the blowing that can circumferentially circulate, a certain moment of fan head can only be aimed at an orientation and be dried, and can not take into account other orientation of circumferencial direction.In addition, the wind uncompressed that existing electric fan is incited out is handled and is directly blown out, and causes air quantity to disperse, and range is limited; Mechanical efficiency is undesirable.Simultaneously, because the rotation of fan head swinging mechanism has been used of a specified duration and can have been produced some noises, make the people feel uncomfortable.
The model utility content
The utility model has designed a kind of novel electric fan; its purpose is to overcome existing electric fan; air quantity disperses; range is limited; especially the electric fan of shaking the head; can not look after each orientation of circumferencial direction simultaneously, and regular meeting produces noise during the rotation of fan head swinging mechanism, makes drawbacks such as the people does not feel well.The utility model provides a kind of electric fan that diverse location is dried simultaneously and had higher mechanical efficiency of not realizing by shaking the head, because wind is handled through overcompression, adopt air-flow to separate far jet distance, therefore can satisfy the requirement that the people of different azimuth dries simultaneously, make human body feel more comfortable.
A kind of electric fan, speed-adjustable motor are installed on the fixed base, it is characterized in that: the main shaft on the motor is connected with inducer with the turbine blade group successively, is connected with short sleeve between every layer of impeller; Be connected with long sleeve between turbine blade group and the inducer; Evenly arrange splitter on the inducer; Fan gas hood integral body is a cavity, and the top is connected with fixed base by fastening screw trip bolt, and top is ring-type inlet air filtration fence, is internally connected with airstrainer at fence; In, the bottom is sealed shape, low profile is to shrink afterwards earlier to expand, the bottom has exhaust outlet.
Described turbine blade group is made of two-layer impeller at least, and every layer of impeller is made up of at least six blades.
The number of blade of arranging on the sheet number of described inducer overdraught shim and the every layer of impeller equates.
Described exhaust outlet is a ring-type; The upper-end surface of exhaust outlet is embedded with bearing, is connected with the end of electric machine main shaft.
Fan gas hood low profile adopts to shrink afterwards earlier to be expanded, and air can be compressed afterwards earlier to discharge.
Working principle of the present utility model is: speed-adjustable motor drives the rotation of turbine blade group, in the fan gas hood, produce certain negative pressure, air sucks gas hood by the inlet hole of fence on the fan gas hood, after in the fan gas hood, being compressed, evenly discharge by inducer with the synchronous rotation of turbine blade group; Because the exhaust outlet of this fan is an annular, wind has reached people's effect that diverse location is dried simultaneously under fan with circumferential uniform blowing out.
Compare with the existing electric fan of shaking the head, the utility model electric fan with air compression after inducer by rotation blow out along circumferential orientation, can satisfy the requirement that the people of different azimuth dries simultaneously, also improved mechanical efficiency to a certain extent simultaneously, reduced noise.

Embodiment
Below in conjunction with drawings and Examples the utility model is illustrated, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
A kind of electric fan of the utility model, as shown in Figure 1, turbine blade group 4 is selected three layers of impeller, and ten blades of every layer of impeller, fixed base 2 are circular, are connected with ceiling board by EXPANSION ANCHOR BOLTS 1; Speed-adjustable motor 3 is installed on the fixed base 2, and the main shaft 5 on the speed-adjustable motor is connected with inducer 9 with turbine blade group 4 successively, and turbine blade group 4, inducer 9 are circumferentially located with spline with main shaft 5 respectively; Three layers of impeller of turbine blade group 4 separate with short sleeve 13; Turbine blade group 4 separates with long sleeve 12 with inducer 9, and sleeve plays the effect of axially locating; Evenly arrange splitter on the inducer, as shown in Figure 4; The sheet number of the splitter 16 of inducer is identical with every layer of impeller blade number.Fan gas hood 8 integral body are a cavity, and the top is connected with fixed base 2 by fastening screw trip bolt 6, and top is ring-type inlet air filtration fence 7, and as shown in Figure 3, the ring-type inlet air filtration fence 7 on fan gas hood top and the vertical guide plate of fence 14 constitute the inlet hole 15 of fence; Be internally connected with airstrainer at ring-type inlet air filtration fence 7; In the fan gas hood, the bottom is sealed shape, low profile is to shrink afterwards earlier to expand, the bottom has ring-type exhaust outlet 11, exhaust outlet is communicated with each air-flow separation lattice on the inducer; As shown in Figure 2.Central authorities at annular exhaust outlet are embedded with rigid bearing 10, and the end of fan main shaft 5 is embedded in the rigid bearing 10, form location, two ends up and down.
