Description
[technical field]
The utility model relates to a kind of electric fan of shaking the head, and it has and continues the function of shaking the head and not shaking the head.
[background technique]
Now on the market, shake the head in order to realize the sustainable of fan, the sustainable many employings two-stage worm and gear of shaking the head of mechanical type and a quadratic crank mechanism are realized.Motor provides power for first order worm gear, and second level worm screw connects the rocking arm of quadratic crank mechanism.Through twice gearing down of worm and gear, reach the rocking arm slow rotation of quadratic crank mechanism, to promote about the fan head shaking the head of rule rate being arranged.
For the control of whether shaking the head, all be the mode of inserting to dial, promptly mention the one-level worm screw, itself and second-stage worm gear are broken away from, stop the transmission of worm gear, after worm and gear stopped transmission, quadratic crank mechanism ran out of steam, and fan head swinging promptly stops.When needing fan head swinging work, only need press the worm screw that is raised downwards, it is contacted with worm gear, worm and gear begins transmission, and quadratic crank mechanism gains impetus, and the fan head has shaking the head of rule rate about getting final product.
Aforesaid way is mode more intuitively, adopts part number also fewer.But it is too poor that topmost shortcoming is a stability.By force dialling of worm screw inserted, increased the wearing and tearing of worm and gear, seriously reduced the life-span of part; Can directly cause gap increasing between a part, noise is excessive, further influences the global stability of fan head; Reduced the service time of fan, caused irreversible infringement to fan.
[summary of the invention]
The utility model technological scheme to be solved is to provide a kind of electric fan of shaking the head, and it has stability preferably.
For realizing above-mentioned purpose; The utility model adopts following technological scheme: a kind of electric fan of shaking the head; It comprises rotating assembly, first order Worm-gear assembly, second level Worm-gear assembly and motor that fan head, base, drive fan head work are shaken the head; First order Worm-gear assembly connects motor, and second level Worm-gear assembly connects rotating assembly, and this electric fan of shaking the head further comprises knob; Rotary knob makes second level Worm-gear assembly engage with first order Worm-gear assembly and drives second level Worm-gear assembly start, thereby drives rotating assembly work.
Compared with prior art, the utility model is realized switching shaking the head of electric fan through knob, has good stable property.
