Abstract
The utility model provides an impeller electric fan which can realize wind blowing to the circumference at an angle of 360 DEG without oscillation. A motor is vertically arranged on a support, an impeller is arranged on a rotary shaft of the motor and blades are uniformly arranged on the impeller. When the utility model is used, the impeller is driven to rotate by the rotary shaft of the motor and the blades on the impeller continuously carry out the wind blowing to the circumference at an angle of 360 DEG. The wind power levels are regulated by changing the rotary speed of the motor.
Description
The utility model relates to a kind of novel electric fan, particularly a kind of do not shake the head can 360 degree ground to around the electric fan of air-supply.Be applicable to and land electric fan, table fan, wall hanging electric fan.
Existing electric fan generally is made up of support, horizontally-mounted motor, blade and protection net.The electric fan of selling on the market is exactly this form.Electric fan comes and goes in the limited angle scope and shakes the head during use, can only be intermittent air-supply concerning a certain concrete wind-engaging place; Do not shake the head though rotate the grid type electric fan, can only in the limited angle scope, intermittence blow yet; Though rotary-type electric fan revolves three-sixth turn air-supply, also be intermittent air-supply to a certain specified place, and strengthened that the space is moving disturbs.Therefore, general land electric fan, table fan, wall hanging electric fan all discontinuously 360 degree to around air-supply.
The purpose of this utility model is that a kind of novel electric fan will be provided, it does not shake the head can be incessantly 360 degree to around air-supply.
The utility model is achieved in that the upright motor of installing on support, installs impeller on the motor rotary shaft, evenly is provided with blade on the impeller.During use, the motor rotary shaft impeller is rotated, blade on the impeller with the air in the impeller to around discharge, form negative pressure in the impeller, air enters impeller in two ends up and down by impeller, again by the blade on the impeller with the air in the impeller to around discharge, go round and begin again like this, the impeller electric fan incessantly 360 degree to around air-supply.For safe in utilization, protection net is installed on motor.
Should be suitable for novel and existing electric fan and compare, do not shake the head incessantly 360 degree to around air-supply, do not have the sensation of impact strong wind, the people is felt comfortably cool, more favourable to health.
Below with reference to accompanying drawing this is suitable for novel being described in further detail.
Fig. 1 is the front view of a kind of specific embodiment structure of the utility model.
Fig. 2 is the utility model embodiment's a plan view.
With reference to Fig. 1, Fig. 2, go up the upright motor (2) of installing at support (1).Motor rotary shaft (3) is gone up installing impeller (4), evenly is provided with blade (5) on the impeller (4).For safe in utilization, go up installation protection net (6), its sideline of only drawing among the figure at motor (2).
During use, connect motor power, motor rotary shaft (3) impeller (4) is rotated, blade (5) on the impeller (4) with the air in the impeller to around discharge, form negative pressure in the impeller (4), air enters impeller (4) in two ends up and down by impeller (4), again by the blade (5) on the impeller (4) with the air in the impeller to around discharge, go round and begin again like this, the impeller electric fan incessantly 360 the degree to around the air-supply.The size of regulating wind-force by the rotating speed that changes motor.
Claims (1)
1. electric fan of forming by support (1), vertically installed motor (2), impeller (4) and protection net (6), the size that this electric fan is regulated wind-force by the rotating speed that changes motor is characterized in that:
A., impeller (4) is housed on vertically installed motor rotary shaft (3),
B. evenly be provided with blade (5) on this impeller (4).
