Abstract
The utility model relates to an omnibearing electric fan. The omnibearing electric fan is composed of a machine shell, a fan cover, the fan blades, an electric motor, a machine body, a shutter driving adjusting control device, a shutter wheel, etc. As the omnibearing electric fan adopts the mode that the blades are backward arranged and a wind delivery device is forward arranged, the wind quantity generated by the backward arranged rotary blades passes through the backward arranged shutter driving adjusting control device and controls the swinging movement of the shutter. Thus, the utility model obtains the wind delivery functions with multiple forms, and satisfies the requirements of the different wind delivery by people.
Description
The utility model relates to a kind of electric fan, is a kind of improvement to existing electric fan.
As everyone knows, no matter existing electric fan is oscillating fan, or box fan, and its function is all comparatively single.Blowing range as oscillating fan only is≤90 °, and box fan then can only be blown along certain circumference, thereby all can't satisfy the air-supply needs of people under wide front yard masses.
In view of the problem of above-mentioned existence, the purpose of this utility model provide a kind of simple in structure, both possessed the air-supply of oscillating fan function arranged, possess the omnibearing electric fan of box fan air-supply function again.
The task that the utility model proposed realizes by following measure:
It has adopted fan blade postposition, the preposition method of blast device, is about to the rearmounted air quantity that rotating blading produced, and by being arranged at the swing of anterior blinds, realizes that it is sent to wind the purpose of both sides.And in order to realize the air-supply of its omnibearing air-supply and 8 fonts, it is provided with blinds driving adjusting Kong system Zhuan Zhi And and blinds is installed on the blinds wheel carrier of a rotatable circle, take turns the asymmetric layout of the blinds vertical line at center by blinds and blinds, make it under the effect of fan blade wind-force, blinds two ends unbalance stress rotates automatically and realizes that it is omnibearing and be the air-supply of 8 fonts by automatic control and produce.
The utility model is owing to taked above-mentioned measure, the amplitude of its straight line air-supply has substantially exceeded the amplitude of common oscillating fan air-supply (≤90 °), its air-supply amplitude can reach 150 °, and with regard to its wind pushing form, also being blown to increase to by single straight line is multiple wind pushing form, thereby has satisfied the requirement of people for different wind pushing forms.
Concrete structure of the present utility model is by providing in the accompanying drawing:
Fig. 1 is the plan view of omnibearing electric fan
Fig. 2 is the right elevation of omnibearing electric fan
Fig. 3 is the structural representation that the blinds of omnibearing electric fan drives control set for adjusting
For ease of understanding the utility model, be elaborated below in conjunction with the embodiment who provides in the accompanying drawing:
Fig. 1, Fig. 2 have provided the structural representation of omnibearing electric fan, and this electric fan drives a few parts such as regulating control adorns 6, blinds wheel 7 by casing 1, fan housing 2, fan blade 3, motor 4, fuselage 5, blinds and formed.On fuselage 5, be provided with timer turn-knob 8, speed governing turn-knob 15, the blinds turn-knob 16 that stops.Blinds wheel 7 is made up of blinds 9, extension spring 10, blinds connection bar 11, blinds wheel carrier 12.The two ends of the every blinds 9 on the blinds wheel 7 are unequal with the distance of the blinds vertical line of taking turns 7 centers by blinds, long end is in a side of blinds vertical line, short end is at the opposite side of blinds vertical line, blinds wheel 7 is installed in blinds wheel supporting axle 13 Shang ， And and can freely rotates around blinds supporting axle 13.Also be provided with the baffle plate 14 of two activities on casing 1, the boss on blinds wheel 7 constitutes the wind pushing mechanism of the electric fan figure of eight.
Fig. 3 has provided the structural representation of omnibearing electric fan blinds driving control set for adjusting.This control gear is by the worm screw 21 that is connected with the fan motor rotor shaft and be installed in institutes such as worm gear 22 in the transmission case 18, driving gearshaft 23, gearwheel 19 and form.Worm gear 22 is contained on the driving gearshaft 23, and gearwheel 19 is driven by driving gearshaft 23.On driving gearshaft 23, also be provided with the clutch 24 of the gear shaft that stops.Clutch 24 is controlled by being arranged at blinds on the fuselage 5 turn-knob 16 that stops.At the end face of gearwheel 19, be provided with chain inner bearing support 20 ， And by chain 26 be arranged on the chain outer support 27 that blinds connects on the bar 11 and be connected, thereby realized driving the purpose of blinds 9 swings by the rotation of gearwheel 19.
For regulating the rotational velocity of blinds wheel 7, blinds wheel supporting axle 13 is provided with blinds wheel speed governing nut 17 and pieces together jack panel 25.
The working procedure of omnibearing electric fan is as follows:
Straight line air-supply: start electric fan, rotor axis of electric drives the worm screw 21, the worm screw 21 that are connected with its afterbody and drives worm gear 22 and driving gearshaft 23, this moment turn blinds turn-knob 16 engaging clutchs 24 that stop, driving gearshaft 23 drives gearwheel 19 and rotates And by being arranged at the chain inner bearing support 20 on the gearwheel 19, drives chain 26, and blinds 9 is swung, thereby make the variation of the distinguished and admirable generating period of fan blade 3 generations, realize its straight line air-supply.Be arranged at the relevant position of two active block stops 14 on the casing 1 by adjusting, the straight line air-supply can be a level, also can be vertical or tilts at any angle.
Figure of eight air-supply: in the straight line air-supply, if adjust two active block stops 14 to several angle, boss on the blinds wheel 7 is clipped between two active block stops 14, because the two ends of blinds 9 are unequal with the distance of the blinds vertical line of taking turns 7 centers by blinds, blinds 9 is under the effect of wind-force, be and periodically come back rotation clockwise, counterclockwise, thereby formed figure of eight air-supply.
Circumference air-supply: when blinds swung to suitable angle, the turn blinds turn-knob 16 that stops broke away from the clutch 24 of driving gearshaft 23, at this moment, driving gearshaft 23 stops operating, and gearwheel 19 also stall ， And stops on a certain angle blinds 9, then, remove two blocks 14 again, blinds wheel 7 is freely rotated under the effect of wind-force, suitably regulate blinds wheel speed governing nut 17, make the rotational velocity of blinds wheel 7 suitable, can realize its suitable circumference air-supply.
