Abstract

The utility model relates to a rocket type motor tooth brush, which is composed of a power switch, a miniature motor, a change gear box, a tooth brush and a shell body, wherein, the shell body forms the shape of a rocket which is ready to launch, and a final stage driven wheel on a multi-change speed gear box in the rocket type shell body is provided with an eccentric rod (8). The bottom of a circular disk (7) is provided with straight grooves (18) having the same diameter, and the eccentric rod is inserted in the straight grooves having the same diameter. The straight grooves having the same diameter which are longer than the radius of the circular disk are positioned at one side of the shaft center of the circular disk. The rotation of the motor is changed into the reciprocating and swinging movement of a brush rod (11) via the movements of the eccentric rod and the straight grooves having the same diameter. The utility model having the advantages of exquisite molding design, reasonable structure and stable driving can effectively eliminate tartar, a timing light-emitting and sounding device is arranged for enhancing the fun of the tooth brush, and the utility model is particularly suitable for assisting children in culturing the favorable habit of brushing teeth.

Description

The rocket type electric toothbrush

This utility model relates to a kind of electric toothbrush, belongs to a kind of device that cleans tooth.

As everyone knows, the general teeth brushing way of people all is manually, is mostly to move back and forth about custom adopts in the moving process of brush, and this brush method is science not, and one can not effectively remove with slot and with the food residues at gingiva place.The appearance of electric toothbrush is for addressing this problem to a great extent.Existing patented product (patent No.: the eccentric impact formula structure of design 94241916.2), but it moves not enough balance, bumps, and uses and feels uncomfortable.Another patented product (patent No.: 90100097.3) adopt to be again that circumference is rotary brush teeth, the rotation radian is very big, cleaning efficiency is not high.

The purpose of this utility model provides a kind of rocket type electric toothbrush; it has the feature that operates steadily and effectively remove tartar; prevent antibacterial growing in slot; reach the effect of thorough cleaning teeth; and regularly the luminous and sounding type device makes the daily routines of brushing teeth become interesting again, is particularly conducive to the good custom that children form cleaning oral cavity.

This utility model is to realize like this.The housing of electric toothbrush is designed to rocket type, the step-by-step variable gear case final stage driven pulley that is positioned at rocket type toothbrush front shell is provided with eccentric rod, the eccentric rod top is inserted in the isometrical straight trough of disk bottom, the wide eccentric rod diameter that is slightly larger than of isometrical straight trough, flute length is less than disc radius, straight trough one end passes to the disk limit, be positioned at disc axis one side, the center-pole and the brush holder support in disk front are rigidly connected, motor is by behind the change gear box, through eccentric rod, the transmission of the isometrical straight trough of disk, become the reciprocally swinging of brush holder support by the rotation of motor reel, thereby realize the reciprocating motion of head toothbrushes, change about 45 ° of pivot angle degree, about reciprocating frequence 150 cycle per minutes in flank of tooth upper edge slot direction.Follow luminous, sounding simultaneously.

Come this utility model is further set forth below in conjunction with Figure of description.

Fig. 1 is this utility model structural representation.
