Abstract
The utility model relates to an electric fan, in particular to the electric fan capable of realizing 360-degree air supply. The electric fan comprises a machine head, a support frame and a base, wherein a bearing, a bearing seat and a speed reducing belt pulley are arranged at the bottom part of the support frame, a miniature low-speed motor is also arranged on the base, the miniature low-speed motor is connected with the speed reducing belt pulley through a belt, and a pair of slide rings and an electric brush are arranged under the belt pulley. Because the utility model adopts the miniature low-speed motor for driving the support frame to rotate, the electric fan can rotate in 360 degrees to reach the 360-degree air supply, and the utility model has the characteristics of simple structure and low cost, and is convenient to use.
Description
Technical field
The utility model relates to a kind of electric fan, particularly a kind of electric fan that can 360 ° of air-supplies.
Background technique
Electric fan is called for short electric fan, and Hong Kong is called fan, and Japan and Korea S are called ventilating fan, is a kind of motoring flabellum rotation that utilizes, and reaches the household electric appliance that make air quicken circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.Be widely used in family, office, shop, hospital and hotels and other places.Electric fan mainly is made up of parts such as fan head, fan blade, guard and control gear.The fan head comprises motor, front and rear cover and the wind pushing mechanism etc. of shaking the head.
Electric fan is by the structural type branch of motor: single-phase capacitance formula, single-phase cover pole type, triphase induction type, direct current and AC/DC series excitation commutator electric fan are arranged, can be divided into domestic electric fan and industrial ventilating fan by purposes.Domestic electric fan has ceiling fan, desk fan, stand fan, wall fan, cabin fan etc.; The branch of shaking the head He do not shake the head is arranged, the rotary blade fan that also has in the desk fan again; Have in the stand fan shake the head, blade-rotating.
The slewing area that traditional oscillating fan is general is less than 90 degree, and the air-supply effective scope is less.
Summary of the invention
The purpose of this utility model just provides a kind of electric fan that can 360 ° of air-supplies.
The technical solution of the utility model realizes by following approach, it contains head, support and base, wherein be provided with bearing, bearing support and deceleration belt pulley in the bottom of support, also be provided with miniature low-speed motor on the base, miniature low-speed motor is connected with the deceleration belt pulley by belt, and the belt pulley below is provided with a pair of slip ring and brush.
The utility model is owing to adopt miniature low-speed motor to drive support to rotate, and makes that electric fan can 360 ° of rotations, reaches the purpose of 360 ° of air-supplies, has characteristics simple in structure, easy to use, with low cost.
