Problems solved by technology

[0002] Existing electric fans use airflow to enter from the back, blow out from the front, and change the wind direction by shaking the head. The angle of the blown wind is very limited, and it cannot form a rotating airflow when used in an indoor space. The straight blowing wind is very uncomfortable. comfortable

Abstract

The invention provides an electric fan, which mainly consists of a base, an upright tube, a lifting regulation and electric control device, an annular knob switch, an annular halo indicator light, an electromotor, a fan blade, a transmission used for a rotary air director, the rotary air director and a safety shield, wherein the annular knob switch can rotate within 360 degrees left and right. The electric fan disclosed by the invention adopts a mode that the fan blade upwards or downwards blows, airflow enters from bottom or top by the air director and rotation and is blown out in a rotating mode at an angle of 360 degrees to the periphery to form rotary airflow, blown air enables people to feel comfortable, rotary airflow can be formed in indoor space without shaking the head, the periphery of the fan can be blown so as to achieve a purpose of further blowing at an angle of 360 degrees, the electric fan can be arranged at will without distinguishing front and back, and the watching focuses at the angle of 360 degrees at the periphery are the same.

Description

Technical field [0001] The invention relates to a blowing device, in particular to an electric fan. Background technique [0002] Existing electric fans use airflow to enter from the back and blow out from the front. The wind direction is changed by shaking the head. The angle of the wind is very limited, and the rotating airflow cannot be formed in the indoor space. The direct wind is very unpleasant. Comfortable. Summary of the invention [0003] In order to solve the problems in the prior art, the present invention provides an electric fan. [0004] An electric fan comprising a base, a vertical pole, a fan blade, a motor, and an electric control device. The vertical pole is arranged on the base, the motor is connected with the fan blade, and the motor and the fan blade are arranged on the vertical pole , The electric control device controls the motor, and further includes a rotating deflector. The blades of the wind blade are set to blow upward or downward. The deflector covers...
