Abstract
The utility model relates to an electric fan, which comprises a bracket and blades, wherein the blades are movably arranged on the upper part of the bracket, the blades also comprise a connecting rod and a swinging rod, the connecting rod does reciprocating rectilinear motion, the swinging rod is movably connected with the connecting rod and is pivoted on the bracket, and the swinging rod does lever motion by adopting a pivoting shaft as a fulcrum; the blades are fixed to the swinging rod, and do swing motion with a definite angle along with the swinging rod. The blades of the electric fan do the swing motion which is similar to shake a fan manually and is rich in spice.
Description
Technical field
The utility model belongs to household appliance technical field, particularly relates to a kind of electric fan.
Background technique
Electric fan is a kind of common household electric appliance, its structure be with some vanes fixed in rotating shaft, with driven by motor rotating shaft rotation, and and then drive blade rotation, produce air-flow with this, the purpose of reach blowing, taking a breath.Such electric fan, motion mode are comparatively dull, except blowing effect, do not have other effect.
Summary of the invention
To be solved in the utility model is that electric fan motion is dull, and the problem that effect is single provides a kind of temperament and interest that is rich in, can be simultaneously as the electric fan of decoration.
The technical solution adopted in the utility model is such: a kind of electric fan, comprise support and blade, blade is movably arranged on support top, it is characterized in that: it also comprises connecting rod and swing arm, connecting rod does reciprocating linear motion, swing arm and connecting rod flexibly connect, be installed on the support, and be that fulcrum is done lever motion with its drive-connecting shaft; Vanes fixed is done the oscillating motion of several angle with swing arm on swing arm.
Further, it also comprises motor, and the motor via reducer drivening rod does reciprocating linear motion.
The utility model also can have another kind of further technological scheme, and it also comprises one group of magnet that constitutes the loop, is wound with coil on the connecting rod, places in the magnetic field of magnet.
The magnet that constitutes the loop can be the 2-8 sheet, and magnet can adopt square or tile shape etc., and scheme is made up of 4 square magnets preferably.
Blade of the present utility model has only a slice, does the action of swing during work, and manner of execution approaches hand shaken fan, there is some diffrent interest very much; Changing the orientation of connecting rod and swing arm, just can change the swaying direction of blade, can be above-below direction, also can be left and right directions; Vanes fixed is on swing arm, and its shape can be selected, as can being that bajiao banana is fan-shaped, goose feather is fan-shaped etc., or even other shapes such as casper.
When adopting the scheme of motor, the motion of speed reducer drivening rod, only need the output of motor is converted into straight line motion, quite simple to those skilled in the art, repeat no more; When by connecting rod, coil, when magnet is formed driving mechanism, connecting rod coils the stator that promptly is equivalent to motor, and magnet promptly is equivalent to the mover of motor, and when connecting power supply, connecting rod promptly moves in magnetic field, and drives the swing arm swing.
The hunting frequency of swing arm is slower in the utility model, and in a sense, decorating action is greater than blowing effect; Blade on the swing arm is removable, can play certain blowing effect with the bigger blade of blowing area when weather is warmmer, when changing other blades, then decorating action preferably can be arranged.
Description of drawings
Fig. 1 is embodiment one a structural representation.
Fig. 2 is the schematic representation of driving mechanism among the embodiment two.
Embodiment
Referring to Fig. 1.Present embodiment comprises motor 1, speed reducer 2, connecting rod 3, swing arm 4, blade 5, support 6.Connecting rod does reciprocating linear motion under the motor and speed reducer effect, and connecting rod 3 is to do reciprocal moving up and down among the figure; Swing arm 4 is articulated on the support 6, and flexibly connects with connecting rod 3, is that fulcrum is done lever motion with its drive-connecting shaft 41; Blade 5 is fixed on the swing arm 4, moves with swing arm.When connecting rod 3 moved up and down, swing arm 4, blade 5 were moveable to 4a, 5a to 4b, 5b place, swing in this angular range.
Referring to Fig. 2.Present embodiment is translator not, carry out transmission with magnet, coil etc., be wound with coil 6 on the connecting rod 3, there are 4 square magnet 7a, 7b, 7c, 7d in the outside, constitute a loop, when coil 6 energisings, connecting rod 3 and coil 6 are promptly made the linear reciprocating motion perpendicular to paper in magnetic field, drive the swing arm motion thus.
Claims (4)
1. an electric fan comprises support and blade, and blade is movably arranged on support top, it is characterized in that: it also comprises connecting rod and swing arm, and connecting rod does reciprocating linear motion, and swing arm and connecting rod flexibly connect, being installed on the support, is that fulcrum is done lever motion with its drive-connecting shaft; Vanes fixed is done the oscillating motion of several angle with swing arm on swing arm.
