Description
Technical field
The utility model is related to a kind of hair cutter, more particularly to a kind of double cam noise reduction 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.
Conventional transmission device is an eccentric wheel, and can only be by eccentric wheel among groove, therefore brings eccentric wheel
Being unable to speed change, eccentric wheel and dynamic cutter head, there are angle abrasion two inner wall belts of groove to hit sound.This secondary design, originality propose
Two two eccentric wheels from gear are driven by a master gear, and eccentric wheel is mounted on two outside of left and right, Ji Nengshi
Existing eccentric wheel speed change can also avoid angle abrasion from bringing shock sound.It is thereby achieved that in the constant situation of dynamic cutter head shear velocity
Under, the motor noise that motor speed descent tape is come declines, and eliminates and hits sound.It to be that there are two eccentric wheels that uniquely there are problems
The structureborne noise brought.But motor speed declines, and can offset the increased structureborne noise in this part.
Utility model content
The purpose of this utility model is for the above problem existing for existing technology, provides a kind of double cam noise reduction haircut
Device, technical problem to be solved in the utility model are how to improve the motion frequency of mobile blade.
The purpose of this utility model can be realized by following technical proposal：A kind of double cam noise reduction hair cutter, 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, and a master is fixedly installed on the output shaft of the drive motor
Gear, rotation connection is there are two from gear on the counteredge, two both sides that master gear is symmetrically distributed in from gear, and same
When engaged with master gear, it is described from a cam is fixedly arranged on the gear with, a stent, institute are fixedly installed on the mobile blade
Stating on stent has two pieces of baffles with cam abutment respectively；The number of teeth of the master gear is more than the number of teeth from gear.
It is provided with a cam, it can be ensured that move back and forth accurately, avoid hitting sound, the number of teeth of master gear is much larger than
It is convex on two cams so as to form the motion frequency for the acceleration from gear, that is, improving mobile blade from the number of teeth of gear
Point selects one with baffle against acting on that cam is made with baffle to be close to by the restoring force of resetting spring frame.
In a kind of above-mentioned double cam noise reduction hair cutter, the master gear is 3 with the gear ratio from gear:1.
In a kind of above-mentioned double cam noise reduction hair cutter, the counteredge is made of metal material.
In a kind of above-mentioned double cam noise reduction hair cutter, the mobile blade is made of ceramic material.
In a kind of above-mentioned double cam noise reduction hair cutter, 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.
