A kind of no blade fan and the steering gear thereof
The utility model relates to no blade fan technical field, refers to a kind of calm blade fan and the steering gear thereof of any rotation especially.
No blade fan is widely used day by day, and the problem of appearance is also more and more, and the steering gear of no blade fan is: be contained in motor driving transmission arm on the base, drivening rod directly draws the chassis, thereby realization fan the steering gear is done 90 degree toward covering rotation.This kind of drive is to have utilized the four-rod linkage principle.So whole the steering gear because on no blade fan the simple running of claimed structure occur easily rotation not steady, beat, the sound, can not specified angle rotate arbitrarily and force rotation.When drying, need move fan, the using effect of the no blade fan of influence back to the user.
The model utility content
The utility model provides a kind of the steering gear of no blade fan of any rotation, can realize reaching any starting point, arbitrarily specified angle travels at the uniform speed, forces the function that turns to self-return.
To achieve these goals, the utility model provides following technological scheme:
A kind of the steering gear that does not have blade fan, it comprises: base, bottom, rotating shaft, fluted disc, slide plate, pallet, motor, driving plate, button frame, button, transparency window, knob, control panel, winding displacement, small gear, wherein:
Said button, transparency window are fixed on the button frame, and are fixedly mounted on the said bottom together with knob, control panel, driving plate, and control panel is connected through winding displacement with driving plate;
Said slide plate is installed on the said pallet, and said motor is fixed on the said pallet, and said motor connects said driving plate;
Said small gear is fixed on the motor, and said pinion drive connects said fluted disc, and said fluted disc is fixed on the chassis;
Said chassis, rotating shaft and pallet locking are together.
Preferably; The steering gear of said no blade fan also comprises: connect electricity greatly and encircle, connect for a short time electricity ring and probe; Saidly connect electricity ring greatly, connect the electricity ring for a short time and be installed in the fluted disc; The said electricity ring of connecing greatly is respectively arranged with power line with connecing for a short time on the electricity ring, saidly connects the electricity ring greatly and connects electricity for a short time and encircle and be connected said probe through said power line respectively, and said probe stationary is electrically connected on pallet and with driving plate.
Preferably, also comprise: sensitive switch, said sensitive switch is fixed on the pallet, and said sensitive switch connects said driving plate, and said fluted disc is provided with the salient point that is used to touch said sensitive switch.
A kind of no blade fan comprises the steering gear of above-mentioned any described no blade fan.
The beneficial effect of the utility model is: this no blade fan is shaken the head and can at the uniform velocity be turned round from arbitrarily angled beginning; But whether open shake the head function all hand reverse vane; And need not mention no blade fan; Any starting point of the no blade fan of realization, any specified angle travel at the uniform speed and force the function that turns to.And the mode of shaking the head adopts gear transmission mode to improve the quality of no blade fan operation; Avoided the test of carrying out because of the problem of shaking the head in the production process repeatedly; Install more simple and convenient; Help improving the quality of product, reduce loaded down with trivial details the doing over again when going wrong of shaking the head of no blade fan, and self-operating is steady.When regulating angle of swing, turn to automatic spacing at every turn, close and auto zero when adjusting spinfunction.
Description of drawings
Fig. 1 is the steering gear STRUCTURE DECOMPOSITION schematic representation of the no blade fan of the utility model.
Fig. 2 is the steering gear assembly structure schematic representation of the no blade fan of the utility model.
Referring to accompanying drawing 1 and Fig. 2; Comprise in the steering gear of the no blade fan that the utility model embodiment provides: base 1, rotating shaft 2, fluted disc 3, slide plate 6, pallet 8, motor 18, driving plate 10, button frame 14, transparency window 12, knob 17, bottom 11, control panel 15, winding displacement 20, on & off switch 13, first self tapping screw 16, small gear 19; Wherein: said button 14, transparency window 12 are fixed on the button frame 14; Said button 14, transparency window 12 also are fixedly mounted on the said bottom 11 through first self tapping screw 16 together with knob 17, control panel 15, driving plate 10, and control panel 15 is connected through winding displacement 20 with driving plate 10; These control panel 15 controlling and driving plates 15 drive motors 18 are rotated.
Said slide plate 6 is installed on the said pallet 8, and said motor 18 is equiped with small gear 19 through on second self tapping screw, the 7 fixing installing pallets 8 on the motor 18, and among the more concrete embodiment, said small gear 19 is in transmission connection with fluted disc 3.And the rotation around fluted disc 3 centers, said fluted disc 3 is fixed on the chassis 1 through the 3rd self tapping screw 22.Said chassis 1, rotating shaft 2 are locked at pallet 8, and among the more concrete embodiment, band cap self tapping screw 23 is locked at said chassis 1, rotating shaft 2 with pallet 8.Assign the rotation time instruction for motor 18 or assign that to rotate number of turns instruction or clockwise and anticlockwise instruction be that this steering gear of may command carries out 360 degree and turns to.
Further; In other embodiments; This steering gear also includes and connects electricity ring 4 greatly, connects electricity ring 5 and probe 9 for a short time; Wherein: saidly connect electricity ring 4 greatly, connect electricity ring 5 for a short time and be installed in the said fluted disc 3, and this connects electricity ring 4 greatly and connect electricity for a short time and encircle on 5 and be respectively arranged with power line, said probe 9 is fixed on the pallet 8.This probe 9 is assemblies, is built-in with spring.Probe 9 little one with connect electricity ring 4 greatly, free adjustment distance when connecing electricity ring 5 and contact for a short time, probe encircles and is electrically connected with the large and small electricity that connects all the time when guaranteeing the steering gear rotation.Connect electricity greatly and encircle, connect for a short time electric ring, fluted disc, pallet, center chassis coincidence; Connect electricity ring greatly, connect the electricity ring for a short time and overlap with the rotating center of the steering gear; Guaranteed probe and the steering gear rotating center apart from remaining constant in the operation process and contacting, guarantee that the steering gear can 360 degree power takings.
Further; In other embodiments; This steering gear also includes sensitive switch 21; This sensitive switch 21 is installed on the said pallet 8, and when the salient point of ring in the fluted disc 3 touches when being installed in the sensitive switch 21 on the pallet 8, this sensitive switch 21 cuts out through motor 18 these the steering gears of control of its control connection and auto zero when adjusting spinfunction.
When fan in use back to the user, but whether the steering gear of the utility model can make no blade fan open shake the head function all hand reverse the fan bodice, and need not mention no blade fan, realize that forcing of no blade fan turns to.
The utility model embodiment also provides a kind of no blade fan, and this no blade fan comprises the described the steering gear of above-mentioned any embodiment.
More than a kind of no blade fan and the steering gear thereof that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
