Description
Technical field
The utility model is related to a kind of hair cutter, more particularly to a kind of vibration damping hair cutter.
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.Wherein, if motor speed is greatly lowered, will significantly drop
Low impact noise and structureborne noise, but haircut head shearing kinetic energy and underspeed can be caused, cause to shear unclean, card hair.
Therefore, by reducing motor speed shear velocity is caused to decline, is worthless noiseless hair cutter selection.
This invention is intended to：Keep haircut head shear velocity, it is ensured that shearing kinetic energy.But be greatly lowered motor speed and
Cancel eccentric wheel, so as to reduce motor oscillating frequency and structureborne noise.It eliminates eccentric wheel and hits impact noise caused by haircut head.
By designing set of device, realize that motor is changed direction transmission mechanism, speed adjusting gear and multi-functional be integrated such as automatically move back and forth.
Utility model content
The purpose of this utility model is for the above problem existing for existing technology, provides a kind of vibration damping hair cutter, this
Utility model is the technical problem to be solved is that the friction between how dropping the transmission parts for reducing hair mobile blade movement, to reach
The purpose of vibration and noise reducing.
The purpose of this utility model can be realized by following technical proposal：A kind of vibration damping hair cutter, hair cutter include by
The columnar handle that first shell and second shell clamping form, which is characterized in that one end of the handle is provided with fixing cutter
Sword and mobile blade, the counteredge are detachably connected with first shell, and the mobile blade, which slides laterally, is connected to fixation
On blade, a stent is fixedly installed on the mobile blade, two be freely rotated are symmetrically arranged on the fixing bracket
Roller, this hair cutter further include a short axle, and a turntable and a bevel gear one are fixedly installed in the short axle, is consolidated in the handle
Surely a drive motor is provided with, the horizontal gear engaged with the bevel gear one is fixedly installed in the shaft of the drive motor
Two, there is odd number protrusion, there are one the recess with the raised rounding off of both sides, institutes for tool between adjacent protrusion on the turntable
It states and an escape groove is offered on stent, the short axle is plugged in escape groove；The roller is resisted against the side wall of protrusion or recess
On.
Drive motor band dynamic bevel gear one rotates, transmission torque to bevel gear one, under the /V of roller and guiding role,
The mobile blade traverse motion being connected with stent, can so as to form shear action, the protrusion set on turntable and recess
With two rollers against and being constantly in and be close to state, so as to eliminate fit clearance, make collisionless in rotation process.
In addition, the protrusion and recess that are set on turntable are odd number (being assumed to be n), when bevel gear one drives horizontal gear two to rotate
One week, will realize can cause mobile blade to occur to swing for 2n times.Assuming that mobile blade swings constant, actually drive motor
As long as 1/ (2n)=0.5/n of the original speed of speed.Even if two cause not of uniform size of bevel gear one and horizontal gear, bevel gear one pass through
Horizontal gear two engages, and realizes that angular speed slows down, but protrusion and the n of recess by being set on turntable are bigger, final or real
Show reciprocating motion speed speedup, therefore this is designed, also can be achieved on motor rotation frequency will be greatly lowered, and also ensure
Speed of having hair cut and kinetic energy, avoid pressing from both sides hair.
Since the protrusion and recess that are set on turntable are characterized in, to be ensured by the both ends distance at center stringent equal
Odd number protrusion and recess, also, protrusion and recess rounding off, therefore, it is also rounding off that mobile blade, which moves back and forth, no
Strike note can be generated.
There are multiple protrusions on turntable, in the case of identical shear velocity, turning for drive motor can be substantially reduced
Speed so as to reduce heat dissipation, reduces noise and vibration.
In a kind of above-mentioned vibration damping hair cutter, there is a belt pulley one in the short axle, the both sides of the stent are distinguished
With a belt pulley two, it is connected between the belt pulley one and the belt pulley two of both sides by flexible elastic band.
In order to ensure that roller is close to the side wall of protrusion or recess, elastic band is provided between short axle and stent, so as to disappear
Except minor impact that may be present.
In a kind of above-mentioned vibration damping hair cutter, the counteredge is made of metal material.
In a kind of above-mentioned vibration damping hair cutter, the mobile blade is made of ceramic material.
In a kind of above-mentioned vibration damping hair cutter, two leads, the activity are symmetrically arranged on the counteredge
Two are provided on blade, and guide groove corresponding with two leads, the lead are plugged in corresponding guide groove respectively.
Lead and guide groove are oriented to the reciprocating motion of mobile blade.
