Abstract

The invention discloses an electric toothbrush, belonging to the technical field of living goods. In order to ensure that the toothbrush can be used for better cleaning teeth, the electric toothbrush adopts the following technical measures: a brush head 4 is arranged on a handle 2, the handle 2 is a Y-shaped structure, the brush head 4 is formed by forming an I-shaped skeleton which consists of two circular discs and one cylinder and planting brush hairs on the inner surface of the I-shaped skeleton, a motor 1 is arranged on the handle 2, a rotating shaft 3 of the motor 1 is provided with a worm rod 5, a rotating shaft of the brush head 4 is provided with a worm wheel 6, the worm rod 5 is meshed with the worm wheel 6 together, and the motor 1 can be used for driving the brush head 4 to rotate by virtue of the worm rod 5 and the worm wheel 6. By virtue of the mode, the electric toothbrush disclosed by the invention has the advantages that because the foremost end of the electric toothbrush is provided with the brush hairs, and the brush head of the electric toothbrush can rotate infinitely instead of performing small-range swing as existing manual toothbrushes and electric toothbrushes, the problems of motion delay, amplitude decrease and the like caused by soft brush hairs can be effectively solved by the electric toothbrush, and the cleaning of innermost cheek teeth and wisdom teeth in the oral cavity can be effectively improved.

Description

Electric toothbrush

Technical field

The invention belongs to a technical field of the articles for daily use.

Background technology

Toothbrush is the dental cleaning that people commonly use, and conventional toothbrush is mainly divided into common manual toothbrush and the large class of electric toothbrush two.The structure of existing manual toothbrush plants bristle of handle.During use, by the friction of bristle and tooth, the food debris on tooth is brushed off.In this process, in order to bristle can rub with tooth, user needs by being constantly applied with down toothbrush or the linear reciprocating motion of front and back.But because bristle has flexibility, it makes the friction of bristle and tooth lag behind the rectilinear motion of handle, the flexibility of bristle, also makes the motion amplitude of friction amplitude much smaller than handle of bristle and tooth simultaneously.Due to these reasons add toothbrush clean be positioned at oral cavity the molar of the inside and wisdom tooth time motion amplitude by the restriction in oral cavity, this creates the terminal a very serious problem.This problem is exactly be positioned at oral cavity the molar of the inside and wisdom tooth can not get the clean wiping same with other teeth.These teeth are especially easily broken down, and this is also that dentist advocates one of reason of destroying wisdom tooth.

Manual toothbrush general under prior art and electric toothbrush, except having above-mentioned shortcoming, also have one to have a not enough place, be exactly it in use, once can only a face of cleaning teeth.So just make can not save during tooth Clean-, do not meet the rhythm of life of modern's anxiety.

Summary of the invention

Tooth is settled accounts better in order to allow toothbrush, this invention takes following technical measures: brush 4 is contained on handle 2, handle 2 is in Y-shaped structure, brush 4 is formed I-shaped skeleton by two disks and a cylinder and is planted bristle at the inner surface of I-shaped skeleton and forms, motor 1 is contained on handle 2, worm screw 5 is equipped with in the rotating shaft 3 of motor 1, the rotating shaft of brush 4 is equipped with worm gear 6, together with worm screw 5 is meshing with worm gear 6, motor 1 drives brush 4 to rotate (as shown in Figure 1) by worm screw 5 and worm gear 6; Or brush 4 is contained on handle 2, handle 2 is in Y-shaped structure, brush 4 is formed I-shaped skeleton by two disks and a cylinder and is planted bristle at the inner surface of I-shaped skeleton and forms, motor 1 is contained on handle 2, small bevel gear 7 is equipped with in the rotating shaft 3 of motor 1, the rotating shaft of brush 4 is equipped with gamp tooth 8, together with gamp tooth 8 is meshing with small bevel gear 7, motor 1 can lead to small bevel gear 7 and gamp tooth 8 drives brush 4 to rotate (as shown in Figure 2).

The benefit done like this is: due to this electric toothbrush is exactly bristle foremost, and the small size swing of the rotation that its brush can be endless instead of existing manual toothbrush and electric toothbrush.Therefore, it can overcome the problems such as the bristle motion delay brought of softness and amplitude reduction effectively, the various toothbrushes under making its clean blind area be significantly smaller than prior art, the innermost molar in oral cavity and the clean of wisdom tooth can be improved.Simultaneously because brush of the present invention rotates, the motion of its existing vertical direction of bristle also has the motion of fore-and-aft direction, and being conducive to it like this can simultaneously to the wiped clean of teeth space.On the other hand, brush 4 of the present invention is in I-shaped, and inner surface is implanted with the bristle for cleaning teeth.Therefore, when rotating in its tooth between the upper jaw and the lower jaw, the upper jaw and the lower jaw tooth can be cleaned simultaneously and have six flank of tooth altogether, greatly shorten when namely three faces (left and right and addendum flank) in its three face (left and right and dedendum flank) and lower jaw teeth that can clean maxillary tooth make for toothbrushing.

detailed description of the invention

In order to allow toothbrush settle accounts tooth better, be particularly positioned at the innermost molar in oral cavity and wisdom tooth, simultaneously also in order to reduce user for toothbrushing time.This invention takes following technical scheme: brush 4 is contained on the handle 2 in Y-shaped structure.Brush 4 is formed I-shaped skeleton by two disks and a cylinder and is planted bristle at the inner surface of I-shaped skeleton and forms.So just form the brush that has three work surfaces (face of cylinder, two circular cards).Wiping upper and lower six simultaneously can be total to a flank of tooth when rotated; In order to drive brush 4 to rotate, the present invention is contained in motor 1 on handle 2, and worm screw 5 is loaded onto in the rotating shaft 3 of motor 1, and the rotating shaft of brush 4 loads onto worm gear 6(as shown in Figure 1).Together with worm screw 5 is meshing with worm gear 6.Such motor 1 just can drive brush 4 to rotate cleaning teeth by worm screw 5 worm gear 6; Another embodiment is on superincumbent part basis, and gamp tooth 8 is reequiped in the rotating shaft of the worm screw 5 in motor 1 rotating shaft 3 being reequiped small bevel gear 7, brush 4.Together with gamp tooth 8 is meshing with small bevel gear 7.Motor 1 just can drive brush 4 to rotate cleaning teeth (as shown in Figure 2) by large small bevel gear.Due to brush 4 have laterally zygomorphic upper three and lower three altogether six can work surface, just can clean six tooth faces when therefore its rotates simultaneously, greatly shorten when making user for toothbrushing.
