A kind of electric fan
Technical field
The utility model relates to a kind of electric fan.
Background technique
Electric fan is that one is utilized the rotation of motoring flabellum, reaches the household electric appliance that make air accelerate circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air, is widely used in family, office, shop, hospital and hotels and other places.Electric fan is mainly comprised of parts such as fan head, fan blade, guard, supporting frame and control units.Fan head comprises motor, front and rear cover and the wind pushing mechanism etc. of shaking the head.
Refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the structural representation of the electric fan of prior art, and Fig. 2 is the structural representation of the control unit of the electric fan shown in Fig. 1.The electric fan of the prior art comprises motor 11, flabellum 12, guard 13 and control unit 14.Described motor 11 is fixedly mounted on the rear net outside of described guard 13.Described flabellum 12 is arranged on the inside of guard 13, and flabellum 12 is fixedly connected with motor 11, and by motor 11, is driven the rotation of flabellum 12.Described control unit 14 comprises Direct box 141, electric capacity 142, switch 143 and power line 144.Described Direct box 141 is fixedly mounted on the rear net outside of guard 13.Described electric capacity 142, switch 143 are installed in Direct box 141.The output terminal of described power line 144 is arranged in Direct box 141.Described motor 11 is also provided with a guide line 111, and these guide line 111 one end are electrically connected with motor 11, and extend to Direct box, and its other end is electrically connected with the output terminal of electric capacity 142, switch 143 and power line 144 in Direct box 141.In addition, a sidewall of described Direct box 141 is provided with aperture (not shown), and described power line 144 is connected with guide line 111 in Direct box 141 through this aperture.For the position of fixed power source line 144 in Direct box 141, keep the good contact of power line 144 and guide line 111, can be set on this power line 144 by an additional routing clip 1441, power line is fixed on Direct box 141.The size of described routing clip is slightly larger than the radius of aperture on Direct box sidewall.
Under normal circumstances, the installation procedure of above-mentioned electric fan is as follows:
(1) at one, produce on line, first motor 11 is arranged on to the rear online of guard 13, and the guide line of motor 11 111 is pulled out and is fixed on guard 13;
(2), in mounted motor 11, an other product line carries out the installation of control unit, comprises electric capacity 142 and switch 143 are installed in Direct box 144, and power line 144 is also fixed on Direct box through the aperture on the sidewall of Direct box;
(3) according to the position of line mouth, Direct box 141 is fixed on guard 13, and guide line 111 is connected with electric capacity 142 and switch 143 in Direct box 141, and power line 144 and guide line 111 are connected Direct box 141 is interior;
(4) finally flabellum 12 and motor 11 are coupled together.
In addition, power line 144 being fixed in the operation of Direct box, first need to be on power line a sheathed routing clip, the external diameter of these cableties is slightly larger than the radius of aperture on Direct box sidewall, then utilize tool tong brute force that cableties are embedded to the aperture on this Direct box sidewall, thereby reach the object of fixed power source line.
But the structure of existing electric fan can be given the problem of serving of being with of producing.Because the control unit of the electric fan of prior art and motor are separation structures, when mounted, need first motor to be arranged on guard, then after pulling out the guide line on motor and being fixed on guard, again Direct box is arranged on guard, therefore in the installation process of whole motor and Direct box, need to install together with guard, do not have the words of guard can not fix Direct box and guide line, when installing, operation is loaded down with trivial details, and the floor space of guard is large, be unfavorable for the optimization of production and the simplification of operation, in factory for large production, be equivalent to increase the cost of time.In addition, because power line need to be fixed on Direct box by routing clip, when routing clip is filled in to Direct box, need to routing clip could be filled in to Direct box by very large brute force, expend so more manpower and time, be unfavorable for the raising of manufacturing efficiency.Generally speaking, when the structure of existing electric fan causes installing, operation is loaded down with trivial details, convenient not, and the inefficiency of assembling has increased the cost of time extraly.Therefore, existing electric fan still has very large room for improvement.
