Abstract

The invention discloses a kind of electric toothbrushes, including brush head, handle and vibrating mechanism, brush head to be connected with handle；The back side of brush head is the globoidal structure of protrusion, the shape of tooth paddy among the shape of cambered surface and the tooth peak to tooth at tooth edge is adapted, so that brush head its back side when vibrating work does not collide with corresponding tooth, or collision only transmits the vibrational energy of very small part brush head to corresponding tooth, the vibrational energy for avoiding brush head amplitude from being embodied largely is delivered to the tooth peak at corresponding tooth edge, and reducing vibration influences the collision of tooth.

Description

A kind of electric toothbrush

Technical field

The present invention relates to a kind of toothbrush, in particular to a kind of electric toothbrush.

Background technique

Electric toothbrush generally includes brush head, handle and vibrating mechanism；Brush head is connected with handle, and vibrating mechanism is usually arranged In the cavity in brush head or handle；Vibrating mechanism driving brush generates the vibration of certain amplitude, and the frequency of vibration usually can be with Reach 30,000 times per minute.

In order to which brush head plants the needs of hair, brush head is set as certain thickness slab construction, while the width of brush head plate is logical The often greater than width of tooth, so that bristle has suitable width, with the width of tray covered teeth；The front of brush head, which is equipped with, plants hair Hole, the root of bristle, which is fixed on, plants in pore, and the back side of brush head is plane, and it is lesser that the edge at the brush head back side is equipped with radius Circle.

Disadvantage of the prior art is that: the width of the plate of brush head is greater than the width of tooth, the back of brush head when brushhead vibration Face is easy to collide with the tooth peak at tooth edge, since the vibration frequency of brush head is very high, while the considerable part of brush head amplitude Energy can pass to tooth, the user of electric toothbrush can be made to generate the feeling of numbness felt bad.

Summary of the invention

The present invention is in order to overcome above-mentioned defect in the prior art, by setting at the back side of brush head to from edge to centre The globoidal structure of protrusion, so that brush head its back side when vibrating work does not collide with corresponding tooth, or collision is only transmitted very The vibrational energy of small a part of brush head gives corresponding tooth, improves the usage comfort of electric toothbrush.

The present invention provides a kind of electric toothbrush, including brush head, handle and vibrating mechanism, brush head are connected with handle；Wherein, The back side of brush head is the globoidal structure of protrusion, the shape phase of the tooth paddy among the shape of cambered surface and the tooth peak to tooth at tooth edge Adaptation, so that brush head its back side when vibrating work does not collide with corresponding tooth, or very small part brush is only transmitted in collision The vibrational energy of head gives corresponding tooth, and the vibrational energy for avoiding brush head amplitude from being embodied largely is delivered to corresponding tooth side The tooth peak of edge, reducing vibration influences the collision of tooth.

It is further preferred that the cambered surface everywhere continuous of the back side protrusion of the brush head, and the single order on its every bit is led Number is continuous, so that the cambered surface has enough smooth and smooth, keeps smooth when cambered surface is with oral cavity dermal contact, simultaneously It has breakked away when being collided with tooth, has reduced effect of the vibrational energy to tooth.

It is further preferred that the width of the brush head corresponding with the later tooth of first molar or first molar Match, the high rear portion in aperture front in oral cavity is low, and the back side of brush head is not easy to collide with the tooth before first molar, usual brush head and the One, which grinds one's teeth in sleep, starts to collide, and the width of the later tooth of first molar and the depth of tooth paddy are both greater than first molar, the width of brush head Using first molar as benchmark optimization design, most easily takes into account and to reduce collision and brush head is kept to clean range with water.

It is further preferred that the height of the cambered surface of the brush head back side protrusion and first molar or first molar are later The corresponding matching of tooth, so that toothbrush optimizes the effect of the most important collision area of tooth.

Compared with prior art, the present invention by by the back side of brush head be set as protrusion globoidal structure so that brush head with The tooth peak of corresponding tooth and tooth paddy match, the influence for avoiding or reducing brushhead vibration to tooth, and raising toothbrush uses comfortable Degree；By setting smooth cambered surface for the brush head back side, keep between the brush head back side and mouth skin smooth is contacted；Passing through will Brush head starts Optimized Matching for first molar, can take into account and reduce collision and keep brush head cleans range with water.

Detailed description of the invention

Fig. 1 is a kind of perspective view of electric toothbrush of the present invention.

The following drawings is marked to mark on it in conjunction with attached drawing:

1- brush head；11- bristle；The back side 12-；2- handle；3- lower tooth；The upper tooth of 4-；41- tooth peak；42- tooth paddy.

Specific embodiment

With reference to the accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention Protection scope be not limited by the specific implementation.

A kind of electric toothbrush of the present invention, as shown in Figure 1, including that brush head 1, handle 2 and vibrating mechanism, brush head are connected with handle It connects, the surface of brush head 1 is equipped with bristle 11, and bristle 11 acts on lower tooth 3；The back side 12 of brush head is the globoidal structure of protrusion, cambered surface Towards corresponding upper tooth 4, the shape of the tooth paddy 42 among tooth peak 41 to the tooth at 4 edge of the shape of cambered surface and upper tooth is adapted, So that its back side 12 when vibrating work of brush head 1 does not collide with corresponding upper tooth 4, or very small part brush head is only transmitted in collision Vibrational energy give corresponding upper tooth 4；Corresponding of the width of brush head 1 and first molar (or first molar later tooth) Match；The corresponding matching of the height of the cambered surface of the protrusion of the brush head back side 12 and first molar (or first molar later tooth).

Further as shown in Figure 1, the cambered surface everywhere continuous of the protrusion of the back side 12 of brush head, and the first derivative on its every bit Continuously, so that the cambered surface is smooth.

Disclosed above is only a specific embodiment of the invention, and still, the present invention is not limited to this, any ability What the technical staff in domain can think variation should all fall into protection scope of the present invention.

Claims
