Abstract

The utility model provides a driving device of an electric shaver, which is composed of a driving wheel, a driven wheel, a floating shaft sleeve, a spring and a cutter frame. The utility model is characterized in that a shaft and a clamping buckle are arranged on the driven wheel; a clamping head, a fork head and a shaft hole are arranged on the floating shaft sleeve; a trench hole and a shaft are arranged on the cutter frame; the shaft on the driven wheel and the hole on the floating shaft sleeve have enough fit length and a tiny fit gap; under the action of the spring, the floating shaft sleeve can slide from top to bottom along the shaft on the driven wheel. The utility model has the advantages of stable transmission, low noise, sharp and comfortable shaving, etc.

Description

A kind of transmission device of electric shaver

The utility model relates to a kind of transmission device of electric shaver, refer to the transmission device of rotary electric shaver especially, belong to the mechanical ﹠ electrical technology field.

The present transmission device of the rotary electric shaver that uses, great majority are to adorn an axle sleeve on the axle of micro machine, the knife rest that will have blade then is enclosed within to be finished on the axle sleeve.There is the deficiency of following several respects in this transmission device: at first be because the mating part length of axle sleeve and knife rest is shorter, and radial clearance is bigger, thereby knife rest can shake when rotating, and causes blade bump guard, produces the sharpness that noise and influence are shaved; Next is that a micro machine can only drive a blade holder turns; The 3rd is because blade is to use fixation with steel wire on knife rest, and blade is very unstable during use, easily produces swing, can cause the sense of discomfort that shaves when serious.

At above-mentioned deficiency, the purpose of this utility model is exactly to provide that a kind of stable drive, noise are little, sharp comfortable, transmission device that a micro machine can drive a plurality of blade holder turns shaves.

The utility model is assembled by driving wheel, driven pulley, spring, floating buss and knife rest.The technical measures that the utility model is taked are to be provided with step-like axle and buckle on described driven pulley; Be provided with the jaw on band inclined-plane at the top of floating buss, circumference place in bottom then is provided with dop, and portion has step-like through hole within it; Have slotted eye in the middle part of knife rest and thereunder be provided with an axle.

The utility model is achieved like this, elder generation on the axle of driven pulley, is enclosed within spring housing on the driven pulley with floating buss again, and dop on the floating buss and the buckle on the driven pulley are interlocked at this moment, will make transmission become very reliable.Axle on the driven pulley has enough lengths of fit and very little fit clearance with the hole of floating buss, so not only can play the correct positioning effect, and can be reduced to minimum level to the influence of radial clearance, floating buss can not produced when rotating rock.At last knife rest is pressed into the top of floating buss, matched with the slotted eye and the axle of knife rest respectively in the jaw and the hole of floating buss, make knife rest when rotating, become very steady, and because the effect of spring can make floating buss slide up and down along the axle on the driven pulley during rotation.So just overcome the defective of blade bump guard, also increased the comfort that shaves simultaneously.

Therefore, the utility model compared with prior art has stable drive, little, the sharp and comfortable advantage that shaves of noise, and can realize that a plurality of knife rests of micro motor for driving rotate simultaneously.

Accompanying drawing 1 is the structural representation that the utility model does not contain driving wheel.

Accompanying drawing 2 is front view and vertical views of knife rest of the present utility model.

Accompanying drawing 3 is front view and vertical views of floating buss of the present utility model.

Accompanying drawing 4 is front view and vertical views of driven pulley of the present utility model.

Accompanying drawing 5 is front view, vertical view and cutaway views that the utility model does not contain knife rest.

An embodiment of the present utility model now is described in detail in detail in conjunction with the accompanying drawings:

The utility model, is made up of driving wheel 1, driven pulley 2, spring 3, floating buss 4 and knife rest 5 to shown in the accompanying drawing 5 as accompanying drawing 1.The utility model is achieved like this, earlier spring 3 is enclosed within on the axle 10 of driven pulley 2, again floating buss 4 is enclosed within on the driven pulley 2, dop 9 on the floating buss and the buckle 11 on the driven pulley are interlocked at this moment, and the axle 10,12 on hole on the floating buss 13,14 and the driven pulley matches, at last knife rest 5 is pressed into floating buss 4, the hole 12 that the axle 6 on the knife rest 5 is inserted on the floating buss, the slotted eye 7 on the while knife rest matches with the jaw 8 on the floating buss.

During use, by micro motor for driving driving wheel 1, driving driven pulley 2 by driving wheel again rotates, fastening by buckle 11 and dop 9 rotates floating buss 4, again because the cooperation of jaw 8 and slotted eye 7, this moment, knife rest can rotate along with the rotation of floating buss, and because the effect of spring makes floating buss slide up and down along the axle 10,12 on the driven pulley 2.
