The oscillating mechanism of tower fan
Technical field
Patent of the present invention relates to the fan technical field, particularly a kind of oscillating mechanism of tower fan.
Background technique
The oscillating mechanism of the tower fan of technology is to rely on the one-way synchronization motor that is contained in the tower fan bottom to promote the fan body motion by lanar four rod mechanism now, and this common structure is made up of one-way synchronization motor, crank, connecting rod, support plate, fixed plate, axis, axle sleeve, slip ring etc.; This oscillating mechanism complex structure, the part of composition is many, the assembling difficulty height, simultaneously power line contacts easily with movable connecting rod, causes the probability rising of power line breakage and on fire, and Security is not high; Rotating the position simultaneously is to rely on plastic and plastic friction, and it is bigger to wear and tear, to Mold Making required precision height; And existing oscillating mechanism bearing capacity is poor, can not drive the water-cooled evaporation tower fan of water tank.
Summary of the invention
Purpose of the present invention solves above-mentioned deficiency exactly, and a kind of oscillating mechanism of the tower fan more steady, that the life-span is long of shaking the head is provided, and it is applicable to water-cooled evaporation tower fan, evaporative type air-cooling fan, upright post type fan, mansion fan.
The solution that patent of the present invention solves above-mentioned technical barrier is as follows:
A kind of oscillating mechanism of tower fan, it is characterized in that comprising dunnage that the fuselage that drives tower fan rotates, be installed in fixed plate on the dunnage, be installed in synchronous machine and hall sensor on the fixed plate, be installed in driving gear on the synchronous machine projecting shaft, with the driven gear of driving gear engagement, install driven gear base, be installed in the magnet in the groove of base and be installed in base plate on the base; Be provided with hollow rotating shaft at described fixed plate, be provided with fixed hole at the center of described base, the underpart of described hollow rotating shaft is inserted in the fixed hole and axially locating; Described hall sensor is installed on the dunnage and with magnet and works in coordination.
Described fixed plate is to form with sheet metal part materials processing, and described hollow rotating shaft riveted joint is installed on the fixed plate; Upper end portion at hollow rotating shaft is equipped with thrust ball bearing, and described thrust ball bearing is between fixed plate and base.
Be provided with hollow cavity on described base, described driven gear is installed in the hollow cavity, and wear washer is installed on Transverse plane on the described hollow cavity; At the boss that is provided with below the described fixed plate more than three, described boss cooperates with wear washer.
Insert in the fixed hole of base the lower end of described hollow rotating shaft, puts into pad more successively, snaps in the circlip that hollow rotating shaft is used, and puts into the axle sleeve of the power line of protection motor in the axis hole of hollow rotating shaft.
Be provided with plural positioning boss in described hollow cavity, be provided with the positioning groove more than two on described driven gear outer wall, described positioning boss cooperates with positioning groove makes driven gear be installed on the base and radial location.
The material of described wear washer is POM or PES.
Described axle sleeve is the silica gel material, axle sleeve and hollow rotating shaft drive fit.
The present invention's advantage compared with prior art is: move more steadily, stop internal power cord and intersect to twine, assembly structure is simpler, and the internal friction damage reduces, and cost also reduces.

Embodiment
Below in conjunction with accompanying drawing and case study on implementation patent of the present invention is further described.
As shown in Figure 1, 2, the present invention is the oscillating mechanism of tower fan, it comprises dunnage 10 that the fuselage that drives tower fan rotates, be installed in fixed plate 8 on the dunnage 10, be installed in synchronous machine 9 and hall sensor 12 on the fixed plate 8, be installed in driving gear 6 on synchronous machine 9 projecting shafts, with the driven gear 4 of driving gear 6 engagements, install driven gear 4 base 3, be installed in the magnet 11 in the groove of base 3 and be installed in base plate 1 on the base 3; Be provided with hollow rotating shaft 82 at described fixed plate 8, be provided with fixed hole 33 at the center of described base 3, the underpart of described hollow rotating shaft 82 is inserted in the fixed hole 33 and axially locating; Described hall sensor 12 is installed on the dunnage 10 and with magnet 11 and works in coordination, and hall sensor 12 is the location sensitive of realization complete machine multiple angles, as: 60 degree, 120 degree, 180 degree, 360 degree rotate.
In the present embodiment, described fixed plate 8 is to form with sheet metal part materials processing, and described hollow rotating shaft 82 riveted joints are installed on the fixed plate 8; In the upper end portion of hollow rotating shaft 82 thrust ball bearing 7 is installed, described thrust ball bearing 7 is between fixed plate 8 and base 3, and it is more smooth and easy that thrust ball bearing 7 rotates hollow rotating shaft 82, and the power line of synchronous machine 9 passes the axis hole of hollow rotating shaft 82 and stretches out the outside.
For driven gear 4 is installed, on described base 3, be provided with hollow cavity 31, described driven gear 4 is installed in the hollow cavity 31, and wear washer 5 is installed on Transverse plane on the described hollow cavity 31; In order to stop tower fan large size friction when shaking the head, make life-span upgrading, at the boss 81 that is provided with below the described fixed plate 8 more than three, described boss 81 cooperates with wear washer 5, and the material of described wear washer 5 is POM or PES.
For hollow rotating shaft 82 being installed on the base 3 and axially locating, after the lower end of described hollow rotating shaft 82 is inserted in the fixed hole 33 of base 3, put into pad 13 more successively, snap in the circlip 14 of hollow rotating shaft 82 usefulness; In the axis hole of hollow rotating shaft 82, put into the axle sleeve 15 of the power line of protection motor; described axle sleeve 15 is the silica gel material; axle sleeve 15 and hollow rotating shaft 82 drive fits, axle sleeve 15 can the better protection power lines when tower fan is shaken the head, and it is impaired that power line is not cut.
In order better to make the driven gear radial location, in described hollow cavity 31, be provided with plural positioning boss 311, on described driven gear 4 outer walls, be provided with the positioning groove 41 more than two, be provided with three positioning boss 311 and three positioning grooves 41 in the present embodiment; Described positioning boss 311 cooperates with positioning groove 41 makes driven gear 4 be installed on the base 3 and radial location.When putting into driven gear 4, the positioning groove 41 of driven gear 4 needs to aim at the positioning boss 311 of base 3, and this positioning groove 41 and positioning boss 311 be driven gear 4 fixedly, and is the power of tower fan rotation.
