Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 has schematically shown a kind of shaking type fan according to a kind of mode of execution of the present utility model.
As shown in Figure 1, 2, this shaking type fan comprises housing 1, rocking handle 2, flabellum 3 and driving mechanism.
Driving mechanism comprises actuation gear 4, overdrive gear 5 and rotating shaft 6.
Shown in Fig. 2,3 and 4, actuation gear 4 is fixedlyed connected with rocking handle 2.Overdrive gear 5 has input end 501 and output terminal 502.Input end 501 and actuation gear 4 engagements.Rotating shaft 6 one ends are fixedlyed connected with flabellum 3, and the other end has shaftgear 7.Shaftgear 7 meshes with the output terminal 502 of overdrive gear 5.
The quantity of overdrive gear 5 can be for one or more.When a plurality of, the input end 501 of first overdrive gear 5 and actuation gear 4 engagements, input end 501 engagements of output terminal 502 and second overdrive gear 5, and the like, until output terminal 502 and shaftgear 7 engagements of last overdrive gear 5.The number of teeth of each overdrive gear 5 is successively decreased gradually.Can realize the speedup effect effectively thus, can make that again the number of teeth differs and is not very big between two gears of engagement, reduce the wearing and tearing of wheel between cog effectively, increase the service life.
In the present embodiment, overdrive gear 5 quantity are three, in other embodiments, can be two, four, five etc., select according to the actual design needs.
In the present embodiment, the material of actuation gear 4, overdrive gear 5 and shaftgear 7 is polycarbonate (PC).In other embodiments, can be polyoxymethylene, polyether-ether-ketone or polyester etc.
Rotating shaft 6 is provided with bearing 8.Bearing 8 is socketed on the outer peripheral surface of rotating shaft 6, and the draw-in groove in the housing 1 is gone in clamping.Bearing 8 countershafts 6 are played a supporting role, and make rotating shaft 6 can realize stable rotation.
The quantity of bearing 8 can or be at least two for one.Be preferably the latter, make rotating shaft 6 when rotating a plurality of strong points be arranged thus, can realize more stable rotation.Improved the stability of a kind of shaking type fan work of the utility model.
In the present embodiment, the quantity of bearing 8 is two, in other embodiments, can be three, four or five etc.
In the present embodiment, coupling shaft 9 is to be inlaid in the blind hole on the rocking handle 2 by the interference of one end to fixedly connected with rocking handle, in other embodiments, can be by modes such as glueing joint, be threaded.
901 on the step of the end face of actuation gear 4 and coupling shaft 9 has elastic tension spare 10.Elastic tension spare 10 1 ends hold out against step 901, and the other end holds out against the end face of actuation gear 4, and it is loosening to prevent effectively that coupling shaft 9 from occurring, and has strengthened the effect of fixedlying connected of 9 pairs of actuation gears 4 of coupling shaft and 2 of rocking handles.Strengthened the stability of the work of a kind of shaking type fan of the utility model thus.
In the present embodiment, elastic tension spare 10 is spring, in other embodiments, can be resilient sleeve or spring washer.
Lever 11 has base 12, and base 12 can support whole fan.Make a kind of shaking type fan of the utility model can be placed on the fooled ornaments usefulness of desktop thus, improved the practicability of a kind of shaking type fan of the utility model.
Lever 11, base 12 and housing 1 can be discrete item, and be fixedly connected by modes such as splicing, welding, riveted joints, or the three in one moulding.Be preferably the latter, not only can take full advantage of the production material thus, and saved assembling procedure, reduced manufacture cost.
In the present embodiment, rotating shaft 6 and shaftgear 7 are that the end interference by rotating shaft 6 is inlaid into to fix in the blind hole on the shaftgear 7 and is connected, and in other embodiments, can be by modes such as spline connection, splicing.Rotating shaft 6 is to fixedly connected with flabellum 3 by the mode that its other end interference is inlaid in the containing groove on the flabellum 3, in other embodiments, can be by modes such as glueing joint, rivet or be threaded.
When a kind of shaking type fan of the utility model used, one of user held lever 11, another hand rotation crank 2; rocking handle 2 drives actuation gear 4 and rotates, actuation gear 4 drive overdrive gears 5, and overdrive gear 5 drives shaftgears 7; shaftgear 7 drives rotating shaft 6 and rotates, and then drives flabellum 3 rotations.Because therefore the number of teeth different (number of teeth is progressively successively decreased) of each overdrive gear 5 can realize the speedup effect, namely during rotation crank 2, can make flabellum 3 to rotate faster than the speed of several times of rocking handle 2 rotating speeds, tens times even hundred times.Because during rotation crank 12, what drive actuation gear 4 was done is continuous rotation, not intermittently rotation, therefore can drive flabellum 3 and realize continuous rotation uniformly, the blowing effect is preferable.
When a kind of shaking type fan of the utility model does not use, can be placed in the fooled ornament of desktop.
Above-described only is mode of executions more of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
