Description
Technical field
The utility model relates to a kind of floor fan, is specially a kind of head motor improvement back is combined with rocking equipment and realizes waving automatically about fan, and adopt rotary positioning mechanism to realize that fan is along the rotation arbitrarily of base for supporting two ends connecting line do.
Background technique
Present fan does not generally have the function of vacillating now to the left, now to the right with lying prone, can only be with manually changing wind direction up and down, and wind ranges is restricted.Along with people use the wide model of floor fan, the floor fan that waves automatically about a kind of can the realization is also arranged on the market now, free rotating shaft all is to adopt universal rotating machinery.Though can reach the function of vacillating now to the left, now to the right, this structure is to adopt a drive unit, promptly directly imports the main shaft that swings with the synchronous machine deceleration arm of force and realizes shaking the head.This device has increased a drive motor and adding electric and oscillatory forces apart from quite big, and synchronous reduction gear is more easy to wear to making, and causes the life-span short and increase the critical defect of cost again, so do not obtain users' approval on promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of swing structure to floor fan to improve, adopt the power of oneself motor to make drive unit, conventional gear, the connecting rod of employing realized the floor fan that swing is shaken the head and the life-span is long simply, and rotation is arbitrarily done in this fan and energy front, rear, left and right.
The purpose of this utility model is achieved in that a kind of floor fan, comprise head, flabellum, base for supporting, safety enclosure, fan housing, rocking equipment and rotary positioning mechanism, head is installed on the safety enclosure, fan housing upper/lower terminal and safety enclosure are hinged, both sides are movably connected on the base for supporting, rocking equipment is fixed on the head, it is characterized in that: described rocking equipment comprises a reduction gear, machine shaft and the eccentric connector that is hinged on the reduction gear driven gear, and the link the other end links at the fan housing; Described machine shaft is stretched the motor rear end certain distance at fan electromotor away from flabellum end edge, and end is provided with screw thread, reduction gear one gear and rotating shaft thread engagement.
Described rocking equipment reduction gear comprises the gearwheel with the rotating shaft threaded engagement, and the coaxial small gear that is provided with is with another driven gearwheel of pinion.
Described fan housing extends a fixed connecting rod to heading, on the link hinged securement connecting rod.
Described rotary positioning mechanism comprises a screw knob, one rubber friction piece between fan housing and base for supporting, have the tapped hole corresponding with knob in fan housing both sides and the corresponding joint of base for supporting, screw knob passes base for supporting, the rubber friction piece is fastenedly connected at the fan housing.
The utility model is by the improvement to rocking equipment, extend the threaded shaft of motor rear end certain distance away from the flabellum end at machine shaft, the action of motor driving swinging mechaism, utilize the eccentric connector rotational position to change the control fan and wave the direction of brushing that changes wind automatically, more existing floor fan increases a drive motor to be realized, obviously can reduce cost more compact structure.
The fan housing is stretched a fixed connecting rod to the heading edge, link is simple in structure, and the structure of whole fan is more tended to be reasonable, and power transmission is effective, life-span is long, and length, the fixed connecting rod angular orientation that changes link can change the fan angular dimension of vacillating now to the left, now to the right.
Base for supporting two ends and neutral position, fan housing both sides are fastenedly connected by screw knob, between base for supporting two ends and fan housing, be provided with the rubber friction piece that screw knob passes, designs simplification, and better effects if, upper and lower, front and rear direction can be rotated arbitrarily, when needing sense of rotation, as long as screw knob is loosened, the fan housing forwarded to be needed the position screw knob to be tightened to get final product again, and relies on rubber friction piece frictional force location.

Embodiment
Below in conjunction with accompanying drawing the utility model floor fan embodiment is elaborated.
As shown in Figure 1, a kind of floor fan comprises head 1 motor, flabellum 2, tubular support base 3, safety enclosure 4, fan housing 8, rocking equipment 5 and rotary positioning mechanism 6.Head 1 is fixedly mounted on the safety enclosure 4, fan housing 8 upper/lower terminals 9 are hinged with safety enclosure 4, both sides 7 are movably connected on the base for supporting, rotary positioning mechanism 6 is positioned at the link position of fan housing 8 base for supporting, rocking equipment 5 housings are fixed on back-end of machine head, and a connection piece 11 is hinged on fan housing 8.
Fig. 2, Fig. 3 is a floor fan rocking equipment linkage structure schematic representation, extend the threaded shaft 13 of motor 1 rear end certain distance away from flabellum 2 ends at machine shaft, threaded shaft 13 is meshed with reduction gear gearwheel 14, the gearwheel 14 coaxial small gears 15 that are provided with, small gear 15 another driven gearwheels 16 of engagement, link 11 the other ends hinged with fan housing 8 are hinged on the edge end face 17 of driven gearwheel away from central shaft, in order to simplify the structure of link, reduce the distance, the power transmission better effects if, extend a fixed connecting rod 18 at the fan housing to heading, end face welds a contiguous block 19 endways, and link 11 two ends are articulated in contiguous block 19 and the driven gearwheel edge end face 17 away from central shaft respectively.When fan electromotor is worked, machine shaft drives 16 actions of rocking equipment reduction gear gearwheel, driven gearwheel behind the reduction of speed utilizes the eccentric wheel rotational position to change the control fan and waves automatically, change the relative driven gearwheel of link length angular orientation, the angle of waving that can regulate fan with contiguous block.
