Description

Electric toothbrush

Technical field

This utility model relates to a kind of toothbrush, especially a kind of can automatic teeth-brushing, automatic water jetting, annotate the electric toothbrush of toothpaste automatically.

Background technology

Existing electric toothbrush, the rotating shaft of its brush is vertical with brush holder.Brush is to contact with facing with the plane rotation mode when rotated, therefore can not be along teeth space, brush teeth along the direction of growth of tooth, easily injure gingiva, and expose root of the tooth.In addition, no matter be existing electric toothbrush or portable toothbrush, all water fillings automatically also equally need to establish in addition water container with traditional approach when brushing teeth and are used, and far do not reach real convenience.

Summary of the invention

This utility model is intended to the defective that exists on the existing electric toothbrush teeth brushing way, and problem that can't automatic water jetting, but provide a kind of teeth brushing way science, also automatic water jetting, annotate the electric toothbrush of toothpaste automatically.

For solving the problems of the technologies described above, the technical scheme that this utility model adopted is as follows;

A kind of electric toothbrush comprises brush, brush holder, micromachine, it is characterized in that: have one to be unidirectional rotation round brush with brush holder in the brush, and be connected with motor through rotating shaft.

The bristle of described rotation round brush is layout different in size, and wherein front end has a small amount of hairbrush and rear end to have tangible gap, and front end is plate-like rear end, garden and is the garden column during rotation.

The roller brush shaft of described rotation round brush is a tubulose, and side has some water injection holes, and front end has the inlet opening, and a water injection pipe that is communicated with pressure water source is communicated with the inlet opening of roller brush shaft.

One toothpaste chamber is arranged in the described brush holder, and the indoor toothpaste outlet of toothpaste connects a dentifrice tube, and stretches into brush.

Described brush holder front end is a crank, and the elastic helix rotating shaft is adopted in the rotating shaft in it.

This utility model also can adopt following proposal:

The upper end of brush internal rotation round brush has its top to have the toothpaste chamber of removable cover, and toothpaste is indoor a small-sized round brush of arranging in the same way with the rotation round brush, and toothpaste squeezes on the small-sized round brush of toothpaste chamber, drives small-sized round brush for toothpaste by the rotation of rotation round brush.

The aneroid battery that is connected with motor is housed in the cavity of brush holder, and motor is positioned at the brush holder end.

Advantage of the present utility model is:

The rotating shaft that has overcome existing electric toothbrush head is vertical with brush holder, therefore can not brush teeth along the direction of growth of teeth space, tooth, easily injures gingiva, exposes the defective of root of the tooth, makes toothbrushing person remain the proper teeth brushing way that bristle is brushed outward by teeth space; Can also automatic water jetting in the time of automatic teeth-brushing and annotate toothpaste automatically, user not only can convenient, fast, cosily reach the purpose that cleans the teeth, but also helps the protection of tooth.

The specific embodiment

This utility model provides full-automatic type and portable two kinds of embodiments at household and two kinds of situations of out on tours:

Embodiment 1: full-automatic type

A kind of electric toothbrush comprises brush 1, brush holder 2, micromachine 3, have in the brush 1 one with brush holder 2 be unidirectional rotation round brush 4.The bristle radial arrangement that is different in size of rotation round brush 4, wherein front end has a small amount of hairbrush and rear end to have tangible gap, and front end is plate-like rear end, garden and is the garden column during rotation, and this helps the outwash of teeth space and facing.Rotation round brush 4 major parts are wrapped in the brush protective cover, and the bristle exposed parts contacts with facing, teeth space, and this touches lip with regard to the bristle of having been avoided horizontal rotation.The rotation of rotation round brush 4 is driven by the motor 3 of (3V) low-voltage DC by brush holder 2 afterbodys, can make it remain the proper teeth brushing way that bristle is brushed along teeth space outward by gingiva according to the direction of rotation of the different parts decision head toothbrushes of the up, down, left, right, before and after of brushing teeth tooth.

The roller brush shaft 5 of described rotation round brush 4 in a tubular form, front end water inlet is from water injection hole 6 ejections of side.Inlet opening place connects a water injection pipe 7, walks around brush 1 and stretches out with pressure water source (tap water or pressure water tank) from brush holder 2 afterbodys and be communicated with.The water spray mode is the bristle root ejection of water from rotation round brush 4, and not only making brushes teeth feels comfortably cool conveniently, but also will keep the health of head toothbrushes for a long time.A hole for water spraying can be established in the brush top, can utilize its flushing teeth space.

One toothpaste chamber 8 is arranged in the described brush holder 2, and the toothpaste outlet in the toothpaste chamber 8 connects a dentifrice tube 9, and stretches into brush 1.The fashion of extrusion of toothpaste can adopt the crushing block extruding on the side of toothpaste chamber, also can adopt inner pressed toothpaste, annotates this dual mode of toothpaste through push switch and realizes.

In intraoral use, brush holder 2 front ends are that the brush holder neck should have suitable flexibility for ease of brush 1.Therefore, rotating shaft should be able to have the pipe internal rotation of certain flexibility.We adopt elastic helix rotating shaft 10.Such as rotating shaft of the rotating shaft of working hard in glove with sewer, pin hole gamma camera or the like.

Micromachine 3 provides power for the rotation round brush, and micromachine is driven by the 3V unidirectional current, and rotating speed is adjustable.Change the direction of rotation that the sense of current can change rotation round brush 4, can manually control.Power supply is general dry battery or rechargeable battery, or adopts transformator to be electrically connected with the city.

In addition, this utility model also can be controlled automatically by sequence circuit and brush teeth, sprays water, annotates the toothpaste overall process, and its control principle is seen Fig. 3.

Embodiment 2: portable

Portable brush 1 is identical with full-automatic type, and difference is not establish automatic water jetting, and since brush holder 2 in equipment battery 11 and to supplying the toothpaste mode to adjust accordingly.

The upper end of brush 1 internal rotation round brush 4 has its top to have the toothpaste chamber 13 of removable cover 12, has one to arrange in the same way and contacted small-sized round brush 14 with rotation round brush 4 in the toothpaste chamber 13.Before brushing teeth, toothpaste is injected on the small-sized round brush 14 of toothpaste chamber, cover removable cover 12.After starting motor 3, the rotation of rotation round brush 4 just drives small-sized round brush 14 and rotates synchronously, and toothpaste is supplied with rotation round brush 14 step by step under the rotation of two round brush.

Present embodiment is owing to be portable, just can not use external power source, load the aneroid battery 12 that is connected with motor 3 in the cavity of brush holder 2, motor 3 is positioned at brush holder 2 ends, brush holder 2 middle parts have that a manual double-pole is two puts switch or microswitch, can arbitrarily control the direction of rotation of rotation round brush.
