Description

A kind of mute hair cutter of anticollision

Technical field

The utility model is related to a kind of hair cutter, more particularly to a kind of mute hair cutter of anticollision.

Background technology

The hair cutter of traditional infant general to emphasize the characteristics of super-silent, anti-pinch is sent out more.Purpose is to reduce infant couple Hair cutter noise pulls the feeling of pain of hair with hair clip hair is cut so that even if infant when being sunk into sleep and playing, is not knowing not Haircut is completed in feel.

According to investigation, hair cutter on the market, generally from mute motor, the mobile blade of ceramic material, eccentric wheel copper Material and haircut head cooperation eccentric wheel material etc. are started with, and are uttered long and high-pitched sounds at a high speed by mute motor reduction motor, ceramic material rigidity It is nylon wear-resistant material to reduce friction sound, eccentric wheel copper material and haircut head cooperation eccentric wheel material, reduces noise.

By the investigation to domestic and international famous haircut of infant device, still using traditional constructional device, noise master It is that motor is uttered long and high-pitched sounds at a high speed to want source, caused by structureborne noise, the eccentric wheel that eccentric wheel causes mobile blade to rock hit haircut head Impact noise.Impact noise caused by wherein eccentric wheel hits haircut head is first, and it is second that motor, which is uttered long and high-pitched sounds at a high speed, eccentric It is the 3rd to take turns the structureborne noise that mobile blade is caused to rock.

This is solved when eccentric wheel rotate, since eccentric wheel and haircut head cooperation are in chamfered fit, above and below eccentric wheel Groove is formed with left and right abrasion, gap is generated and brings shock haircut capitiform into huge noise.One attachment device of this secondary design, By eccentric wheel rotary motion, it is changed into and only moves left and right mode, so as to which cooperation deviation will not be caused because of upper and lower abrasion, reduces Impact noise.Realize the mute haircut effect of anticollision.

Utility model content

The purpose of this utility model is for the above problem existing for existing technology, provides a kind of anticollision mute haircut Device, technical problem to be solved in the utility model are how to be optimized by the trigger architecture to mobile blade, eliminate and pass The noise that components hit generates in system cam-type trigger architecture.

The purpose of this utility model can be realized by following technical proposal：A kind of mute hair cutter of anticollision, hair cutter Including the columnar handle formed by first shell and second shell clamping, which is characterized in that one end of the handle is provided with Counteredge and mobile blade, the counteredge are detachably connected with first shell, and the mobile blade slides laterally connection There are one being set on counteredge, between the counteredge and mobile blade mobile blade is driven to be located at counteredge just Intermediate resetting spring frame, the handle is interior to be equipped with drive motor, is fixedly installed turntable in the shaft of the drive motor, institute It states and a bolt is fixedly installed at the eccentric position of turntable, set in the first shell there are two catch, opened on the catch Equipped with location hole, this hair cutter further includes a slide bar, and the both ends of the slide bar are plugged in respectively in two location holes, the slide bar Middle part be fixedly installed a triggering block, the guide groove vertical with slide bar is offered in the triggering block, the bolt is plugged in In the guide groove, on the mobile blade there is a mounting hole, there is a connector in the triggering block, the connector is inserted It is located in the mounting hole.

Drive motor is electrically connected with the accumulator being arranged in handle, drive motor drive turntable rotation, inserting on turntable Pin is due to being arranged on eccentric position, and in turntable rotation, bolt is rotated around center of turntable, and eccentric lobe rotation position can be analyzed to X, y-axis position, the movement of x-axis position causes litter to horizontally slip, the movement of y-axis position causes eccentric lobe upper and lower in slide bar sliding slot It slides；X, y location decomposes, and has prevented above and below litter movement appearance, the rapidly vibration that the movement of two directions of left and right is likely to occur, has generated Noise.Further, since x-axis moves left and right, it is possible to eccentric wheel be avoided to hit the chamfered fit to form groove with haircut butt, and made It is happened into wearing up and down and moving left and right two kinds；In addition, the friction in triggering block is sliding friction, connector does not just rub It wipes, it is desirable that installation is close.

So as to horizontally slip with moving slide-bar in location hole, then slide bar drives mobile blade to be relatively fixed blade and back and forth transports It is dynamic, it is formed and shears power, in this structure, slide bar is positioned by location hole, and bolt promotes slide bar or so in guide groove along inner wall It slides, rolling friction is belonged between triggering block, and be constantly in contact condition, so as to eliminate conventional cam formula hair cutter Triggering is hit, and improves the mute performance of hair cutter.

In a kind of above-mentioned mute hair cutter of anticollision, the counteredge is made of metal material.

In a kind of above-mentioned mute hair cutter of anticollision, the mobile blade is made of ceramic material.

In a kind of above-mentioned mute hair cutter of anticollision, two leads, institute are symmetrically arranged on the counteredge It states and two is provided on mobile blade guide groove corresponding with two leads, the lead are plugged in corresponding guide groove respectively It is interior.

Lead and guide groove are oriented to the reciprocating motion of mobile blade.
