Abstract

The utility model relates to a flat-rotating electric toothbrush which is composed of a toothbrush head, a toothbrush handle, an electric machine, a power supply, a switch, and a drive mechanism. The flat-rotating electric toothbrush is characterized in that the toothbrush head is divided into a brush plate and an outer shell; the lower part of the brush plate is provided with a worm wheel matched with a worm screw; the worm wheel is engaged with the worm screw in the toothbrush handle; the other end of the worm screw is connected with the shaft of the electric machine through a speed reducing gear wheel pair. The utility model adopts electrical energy (a battery, or an ac power supply, or a dc power supply) to drive the electric machine. The brush plate is driven by a speed reducing gear wheel and the worm screw. The brush plate can rotate on a plane surface, the speed is homogeneous, the force moment is large, and the utility model can be used for thoroughly cleaning the surfaces and the slots of teeth, polishing and removing residual food.

Description

The plane rotating electric toothbrush

This utility model belongs to electric toothbrush.

As everyone knows, the general sanitation and hygiene standard of tooth is: the pure white light of dental surface, do not have food waste in the teeth space.The toothbrush that people use now mostly is with artificial power, cleans that tooth is time-consuming, effort and weak effect.Also have a kind of known powered toothbrushes in addition, it be with toothbrush being the axle center, do rotation in the space or move up and down, the purpose of design is the food of effectively rejecting in the teeth space.But, when this design 1-rotates toothpaste is thrown away tooth, make it to be not fully utilized; 2-brushes tooth and is rotated down to reject teeth space, and the brush lower tooth then rotates up, and rotation will commutate, thereby makes drive mechanism complicated; 3-hinders gingiva, owing to be that circular arc contact between the bristle of rotation and the tooth axially, has a large amount of hairs can the contact gingiva when brushing teeth root, otherwise just brushes the facing less than the root of the tooth place, can not accomplish to clean tooth comprehensively.

The purpose of this utility model is to provide a kind of plane rotating electric toothbrush, and this toothbrush can clean, polish the full surface of tooth, and residual food in the efficiency ground rejecting teeth space, and is simple in structure.

The plane rotating electric toothbrush is made up of brush, brush handle, motor, power supply, switch, drive mechanism, it is characterized in that brush is divided into brush plate and shell, the bottom of brush plate is the worm gear that matches with worm screw, worm engaging in worm gear and the brush handle, the other end of worm screw are paid through reduction gearing and are connect motor reel.

This utility model adopts electric energy (battery or power of alterating and direct current) drive motors, drives brush plate by reduction gearing and scroll bar, the rotation of brush plate plane, and speed is even, and moment is big, can comprehensively clean, polish tooth face and seam, rejects food residual.

As above-mentioned plane rotating electric toothbrush, it is characterized in that having on the brush 2 to 3 brush plates.Use to improve brush speed and to adapt to the adult.

As above-mentioned plane rotating electric toothbrush, it is characterized in that brush and brush handle are divided into two bodies, be connected structure therebetween.This structure can be changed easily with old bristle, saves cost of use.

Fig. 1, plane rotating electric toothbrush structural representation.Wherein, 1 brush, 2 brush plates, 3 shells, 5 worm screws, 6 brush handles, 7 reduction gearing are paid, 8 motors, 9 batteries, 10 bottoms, 11 springs, 12 switches, 13 water proof rings, 14 joints.

Fig. 2 is the sketch map of brush plate 2 among Fig. 1.Wherein, 4 worm gears.

Fig. 3 is the sketch map of worm screw 5 among Fig. 1.

Fig. 4 is the structural representation of Fig. 1 center tap 14.

Fig. 5 cleans schematic diagram.Wherein, 15 teeth, 16 teeth spaces.

Plane of the present utility model rotating electric toothbrush as shown in Figure 1, with battery 9 drive motors 8, motor 8 through reduction gearing pay 7 and worm screw 5, worm gear 4 drive brush plates 2 and in shell 3, do the plane rotation, hair on the brush board 2 contacts with the tooth face with the plane, the way of contact as shown in Figure 4, no matter the tooth limit, in still root of the tooth all can brush, thereby can clean comprehensively and polish.16 one-tenth low-angles of the outer ring hair and the teeth space of brush plate 2 also can effectively be picked out the residue in the teeth space.
