Abstract
The utility model discloses an electric fan, which comprises blades, a rotating shaft, a motor and a power supply. The motor drives the rotating shaft to rotate. The blades are installed at one end far away from the motor of the rotating shaft and rotate with the rotating shaft. The electric fan additionally comprises LED (Light Emitting Diode) lamps and a single-chip microcomputer. The number of the blades is two and the two blades are symmetrically distributed. The number of the LED lamps is more than four and the LED lamps are arranged on one blade. The rotating shaft is hollow. The single-chip microcomputer is arranged in the rotating shaft. Each LED lamp is connected with the single-chip microcomputer through a conducting wire. The single-chip microcomputer independently controls the on and off of each LED lamp. The power supply is used for supplying power to the motor and the single-chip microcomputer. Since the LED lamps are arranged on the blade, the on and off of each lamp is independently controlled by the single-chip microcomputer and the on-off time of different LED lamps is controlled through a program in the single-chip microcomputer, different patterns can be formed by the LED lamps when the blade rotates by using the visual stay effect of human and the ornamental effect is better; since the LED lamps are fixedly arranged between the transparent thin films of the blade, the effects of protecting the LED lamps and preventing the LED lamps from falling can be realized.
Description
Technical field
The utility model relates to a kind of electric fan, belongs to household appliance technical field.
Background technique
Electric fan is a kind of motoring flabellum rotation that utilizes, and reaches the household electric appliance that make air accelerate circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.The small-sized fans that has at present hand-held, is used powered battery, and volume is little, and power is low, easy to carry, is suitable for carrying out using, but this fan looks more dull, and appreciation effect is poor.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, can form the electric fan of various patterns when a kind of rotation is provided.
The technical solution adopted in the utility model is: a kind of electric fan, comprise blade, running shaft, motor and power supply, driven by motor running shaft rotates, blades installation is the one end away from motor at running shaft, along with the rotation of running shaft, rotate, also comprise LED lamp and single-chip microcomputer, described blade has two, symmetrical, the quantity of described LED lamp is greater than 4, be arranged on one of them blade, described running shaft hollow, single-chip microcomputer is located in running shaft, each LED lamp is all connected with single-chip microcomputer by wire, single-chip microcomputer is independently controlled the opening and closing of each LED lamp, described power supply is to motor and single-chip microcomputer power supply.
As the preferred technological scheme of the utility model, described in LED lamp is installed blade by two-layer transparent thin-membrane, formed, the edge of two-layer transparent thin-membrane is fixed together, described LED lamp is fixed between two-layer transparent thin-membrane.
The utility model is provided with a plurality of LED lamps on blade, utilize single-chip microcomputer independently to control the opening and closing of each lamp, flickering the time of the LED lamp that programming Control is different in single-chip microcomputer, utilize people's vision to stop effect, when blade rotation, LED lamp can form different patterns, has stronger appreciation effect.LED lamp is fixed between the transparent thin-membrane of blade and can plays protection LED lamp, prevent the effect that it drops.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric fan of the present utility model.
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Embodiment
As shown in Figure 1, this electric fan, comprise blade 1, running shaft 2, motor 3 and power supply 4, driven by motor running shaft rotates, blade 1 is arranged on running shaft 2 away from one end of motor 3, along with the rotation of running shaft, rotate, also comprise LED lamp 5 and single-chip microcomputer 6, described blade 1 has two, symmetrical, and the quantity of described LED lamp 5 is greater than 4, be arranged on one of them blade 1, the blade 1 that LED lamp 5 is installed is comprised of two-layer transparent thin-membrane, and the edge of two-layer transparent thin-membrane is fixed together, and LED lamp 5 is fixed between two-layer transparent thin-membrane; Running shaft 2 hollows, single-chip microcomputer 6 is located in running shaft 2, and each LED lamp is all connected with single-chip microcomputer 6 by wire, and single-chip microcomputer is independently controlled the opening and closing of each LED lamp 5, and described power supply 4 is given motor 3 and single-chip microcomputer 6 power supplies.
During use, motor 3 driven rotary axles 2 rotate, and running shaft 2 band moving vanes 1 rotate, and the LED lamp on Single-chip Controlling blade was opened or closes with the different time lags, can on blade, form different patterns, had fabulous appreciation effect.
