Abstract

The utility model provides an electric shaver including a shell (40) doubling as a handle used for installing a battery, a motor (37) and a circuit board. The end of the handle is provided with tool bits consisting of a stationary knife (32) and a locomotory knife (31). The two groups of tool bits are respectively arranged on both ends of the handle, and a switching device putting the two tool bits alternately in working order. The electric shaver adopts two tool bits working alternately so that the unworkable one can be replaced by the other one, or one of the tool bits is provided with a stationary knife blade with a comparatively big opening while the other one is provided with a stationary knife blade with a comparatively small opening. Compared with the prior art, the electric shaver adopts one electric shaver while achieves the function of the two so as to save the cost. In addition, the user can cut hairs of different thicknesses conveniently due to stationary knife screens with different openings and can conveniently cut hairs of different parts with the tool bits of different types.

Description

Electric shaver

Technical field

The utility model relates to a kind of electric shaver, belong to the dry shaver technical field in the operation.

Background technology

Electric shaver constitutes the cutting working head by guard shape stationary knife and moving knife, has reciprocating type and rotary two kinds.The reciprocating electric razor moving knife is installed on the reciprocating beat frame, and the beat frame is through connecting rod or be directly installed on the eccentric shaft, and eccentric shaft is by driven by motor.The rotary electric shaver moving knife is installed on the rotating shaft.Electric shaver in the past has only one group of cutting working head, or title cutter head, and since the blade in the moving knife be close to the moving knife guard and carry out work as high-speed friction, be very easy to the wearing and tearing rust, and the cost of razor tool tip part to account in whole the product cost only be fraction, so abandon as electric shaver rust, very unfortunate.In addition, the user's of electric shaver hair has different thickness degree, only has a kind of stationary knife of aperture to use inconvenience, and capricious face curved surface also tool setting capitiform formula different needs is arranged.

Summary of the invention

At above-mentioned deficiency, the utility model is exactly that a kind of electric shaver that possesses a plurality of cutter heads will be provided.

The electric shaver that the utility model provides, the housing that is used to install battery, motor and circuit board that the double as handle is arranged, the cutter head that is made of stationary knife and moving knife is installed on the handle end, said cutter head has two groups of two ends that are installed in handle respectively, two groups of cutter heads are that single head is rotary respectively, multi-head rotary, reciprocating type in two kinds identical or different two kinds, make two cutter heads alternately enter the switching device shifter of duty in addition.

The electric shaver that the utility model provides, because but two cutter heads of alternation have been installed, so just might when a cutter head is out of use, use another cutter head instead, or on a cutter head, use the bigger stationary knife guard in hole, the less stationary knife guard of installing hole on another cutter head.Compared with prior art, the utility model is realized the function of two electric shavers with an electric shaver, provide cost savings, the stationary knife guard in different holes allows the user cut the hair of different thicknesses more easily in addition, and multi-form cutter head then allows the user cut the hair at different positions more easily.

The electric shaver that the utility model provides, the said switching device shifter that makes two cutter heads alternately enter duty comprise two moving knife are connected two motors respectively, and connect battery and two motors with a power change-over switch; Or two moving knife are connected on the two end axles of a motor, and two moving knife and motor are installed in one move on the seat, also install one and stir the plectrum that moves seat, move two endpoint locations that seat moves and be that this moving knife contacts with stationary knife and another moving knife breaks away from stationary knife and another moving knife contacts with stationary knife and this moving knife disengaging stationary knife; Or two moving knife are installed in and move on the seat, also install one and stir the plectrum that moves seat to move two endpoint locations that seat moves be that this moving knife is connected with motor and another moving knife and motor lose that connection and another moving knife are connected with motor and this moving knife loses with motor and is connected.

The electric shaver that the utility model provides, on the moving direction of said change-over switch stopper is arranged, this stopper is connected with the cutter head outer protective cover, and this stopper loses barrier effect when protective cover takes off, to make things convenient for the user to switch, an end cutter head of promptly not plucking protective cover can be by error starting.

The electric shaver that the utility model provides, said motor are installed in and depart from moving knife drive axis position, and motor shaft is connected with the moving knife driving shaft by transmission device.
