Abstract
The utility model relates to a rotary electric fan. The prior electric fan technically has the following defects: the fan head cannot rotate circumferentially, so that the blowing scope is limited; and the inclination of the fan head cannot be automatically changed when the fan works, so that the upper and the lower space of a house cannot be blown at the same time. In order to solve the technical defects of the prior art, the utility model provides a rotary type multi-functional electric fan which has low cost and is practical. The rotary type multi-functional electric fan comprises one or more fan heads, a main electric motor, a rotation control electric motor, an inclination control electric motor, a support, a rotating crankshaft, a fixed crankshaft, a connecting rod and a rotating hollow shaft. The main electric motor drives fan blades to rotate; the rotation control electric motor can realize the 360-degree rotation of the fan heads; and the inclination control electric motor drives the fan heads to longitudinally incline back and forth. The rotary type multi-functional electric fan can blow cool wind to the whole indoor space, and is applicable to household use, and the staffs in meeting rooms and offices.
Description
Technical field:
The utility model relates to a kind of rotary fan, but the fan head wing drop.
Background technique:
The extensive use in daily life of existing electric fan, but have the following disadvantages: (1), fan head can not be done the circumference rotation, and the scope of blowing is restricted.(2), can only regulate the inclination of fan head in advance, in the fan running process, can't change automatically, can not make top, house and lower space all blow to wind.
Summary of the invention:
The utility model is in order to overcome some defectives of prior art, and design has one or more fan heads (1), main motor (4), Spin Control motor (17), control motor (2), support (11), rotary crankshaft (10), fixed crankshaft (6), connecting rod (5), revolving hollow spindle (7) tilt; Main motor (4) is housed on the support (11), and the electric drive axle (3) of main motor (4) links to each other with fan head (1); Fan head (1) is installed in parallel on the same support (11); Control motor (2) is equipped with on the fixed plate of support (11), the rotating shaft of tilting to control motor (2) links to each other with an end of connecting rod (5) by rotary crankshaft (10), and the other end of connecting rod (5) is fixed on the fixed crankshaft (6) on revolving hollow spindle (7) top; Support (11) is fixed on the top of revolving hollow spindle (7) by pin, and the bottom of revolving hollow spindle (7) links to each other with Spin Control motor (17).
The beneficial effects of the utility model are, realize 360 ° of rotations of fan head, and fan head can regulate vertical angle automatically in operation process, thereby have promoted the practical usefulness of electric fan.
