Abstract
The eccentric rod that a kind of big angle of revolution electric toothbrush head, including brush holder support, brush and inclination are installed in the brush holder support, the head side of the eccentric rod, which is arranged eccentric sleeve and clamps wear-resisting sleeve, constitutes assembly sleeve device；The side of the brush plugs eccentric sphere；Arc chute is arranged in the other side；The brush is installed on the head of the brush holder support by axis, is limited by the positioning pin protruded into the arc chute, and the eccentric sleeve device of the eccentric rod and the eccentric sphere are slidably matched and drive the brush reciprocally swinging.The electric toothbrush of the utility model, which passes through the eccentric sphere cooperation in eccentric sleeve device and brush, as a result, realizes clearance fit, and conventional rotary is overcome to be also easy to produce dead angle, the small difficult point of amplitude of oscillation angle.This structure is simple, and flexibly, swing angle is big, and noise is small, long service life for rotation.
Description
Technical field
The utility model relates to toilet article articles, and flexibly more particularly, to a kind of rotation, swing angle is big, and the service life is long, noise
Small big angle of revolution electric toothbrush head.
Background technique
The appearance of electric toothbrush facilitates the life of the people.Currently, the main component of electric toothbrush: head toothbrushes, by brush head
Motion mode is divided into two major classes type: linear reciprocation swings brush head and reciprocating rotating (circumgyration) brush head.And reciprocating rotating brush head
It is divided into two kinds of basic systems again: realizes reciprocating rotating using link mechanism and realize reciprocating rotating using eccentric stiffener.
The brush-head structure of the reciprocating rotating of traditional eccentric structure driving, structure is simple, is limited by the brush holder support bodily form, conventional inclined
The heart is away from 0.5~1.8mm；The position radius of gyration are as follows: 4.0~8.0 under conditions of the parameter restricts and do not generate interference, most
Big angle of revolution can only achieve 27 degree, otherwise easily generates dead angle, stuck phenomenon occurs or effective torque is too small, noise is excessive existing
As.Without practical application value.Due to the rigid eccentric structure of application, it is necessary to which objective reality fit clearance, for a long time, noise can increase
Greatly, swing angle also declines.
Utility model content
To solve not working existing for existing electric toothbrush technology, conventional rotary is also easy to produce dead angle, and swing angle is small,
Noise is big, service life short technical problem, and the utility model provides a kind of big angle of revolution, service life long big angle of revolution electric toothbrush
Head.
To achieve the above object, the utility model discloses a kind of big angle of revolution electric toothbrush heads, including brush holder support 2 and brush
1, it is characterised in that further comprise:
The eccentric rod 4 being installed in 2 inner cavity of brush holder support is tilted, it is eccentric by the setting of brush side in 4 head of eccentric rod
Sleeve 42, wear-resisting sleeve 43 and shaft 41；The bias sleeve 42 is integrally formed with eccentric rod 4；Wear-resisting sleeve 43 and shaft
41 be respectively separate piece；Shaft 41 is tightly packed on the central axis limit hole of 4 central axes O '-O ' of eccentric rod and wear-resisting sleeve 43 is mounted in partially
To which the eccentric rod 4 driven by a motor can be around central axes O '-O ' reciprocally swinging in heart sleeve 42 and in shaft 41；
Eccentric sphere 12 is arranged in the side of the brush 1, and arc chute 13 is arranged in the other side；The brush 1 passes through axis 5
It is installed on the head 21 of the brush holder support, is limited by the positioning pin 6 protruded into the arc chute 13, and the eccentric rod 4
It is driving link that eccentric sleeve 42 and wear-resisting sleeve 43, which constitute assembly sleeve device, and the bias sphere 12 is Passive part, driving link
Arc rotary drives eccentric sphere to make corresponding sports and drives 1 reciprocally swinging of brush to be slidably matched.
Wherein: the positive top in head of the eccentric rod 4, which is inserted, stretches out shaft 41, and 41 oblique cutting of shaft is into 2 head of brush holder support
In 21 axis hole；The angle of the central axes (O-O) of the central axes (O '-O ') and the brush holder support 2 of the eccentric rod 4 be 1~5 degree from
And two central axes coaxially do not increase head toothbrushes angle of revolution to increase the eccentricity of eccentric sleeve and maximize.
Wherein: the tail end of the brush holder support 2 inserts attachment base 3, and the front end of the attachment base 3 is set can be with the eccentric rod 4
The accentric support ring 31 of tail end cooperation.
Wherein: the eccentric sleeve 42 and wear-resisting sleeve 43 of the eccentric rod 4 constitute assembly sleeve device be arcuate bottom flute profile,
Open circles taper, spherical shell shape or hollow ellipse taper, the bias sphere 12 and the eccentric sleeve 42 and 43 structure of wear-resisting sleeve
At assembly sleeve device inner surface sliding contact.
Wherein: the bias sphere 12 is metalwork or is plastic cement wear-resistant material.
Wherein: the range of 4 eccentricity of eccentric rod is 2.5-3.5mm；The outer diameter of the bias sphere is Φ 2.0- Φ
3.0mm。
Wherein: the swing angle of the brush 1 is 30-60 degree.
Wherein: the axis 41 is made with axis 5 and positioning pin 6 of stainless steel.
Wherein: the wear-resisting sleeve 43 is made of stainless steel thin slice.
As a result, in the big angle of revolution electric toothbrush head of the utility model, the inclination of eccentric rod 4 is installed on 2 inner cavity of brush holder support
In, the positive top in the head of eccentric rod is provided with the shaft with the dynamic cooperation of the axis hole on brush holder support head, and the head side of eccentric rod is set
Eccentric sleeve device is set, fit clearance is realized by the eccentric sphere on the eccentric sleeve device and brush of eccentric club head.
Flexibly, elasticity is good, and swing angle is big, and noise is small, long service life for rotation.
Since eccentric rod is that inclination is installed on brush holder support inner cavity, and the positive top in head (central axes) of eccentric rod is arranged turn again
Axis, eccentric rod can make eccentric rod inclined in this way around the central axes reciprocally swinging of itself when motor drive drives eccentric rod
The heart realizes brush head large-angle slewing (being greater than 40 degree or more) away from that can increase to 2.5-3.5mm.Experimental data shows
Low noise operation (away from brush head 10cm, being less than 70DB) can be realized under dry conditions, be saturated toothpaste solution, brush head 100%
Rotary axial loads under 170gf pressure, and after accumulation work 100 hours, average noise is less than 65DB, brush and brush holder support and grinds with coincidence
Damage amount is less than 0.3mm, much meets 13.5 hours and accumulates the requirement used.
