Abstract

The utility model discloses a rotary electric toothbrush, which relates to a device for brushing tooth. The movement of the ordinary toothbrush in the mouth cavity is limited, and the wrong transversal tooth brushing can not be prevented. The inner part of a casing (4) of the utility model is provided with a battery (5) and a motor (3), and the motor (3) drives a rod-shaped toothbrush rod (2) to rotate around the shaft center of the toothbrush rod (2) by a speed reducing gear (6) and a driving shaft (8). The periphery of the other end of the toothbrush rod is provided with brush bristles (1), and the outer part of the casing is provided with a switch (7). The brush bristles can rotate to brush teeth without the vibration of the toothbrush rod, so the difficulty of limited movement in the mouth cavity can be solved. The toothbrush rod is sheathed on a drive shaft. If people brush the teeth transversely, the toothbrush rod can fall off.

Description

Rotary electric toothbrush

This utility model relates to a kind of device of brushing teeth.

Ordinary toothbrush is made up of handle and bristle two parts.Correct method for brushing teeth is the up-down vibration handle, and vertically brush is moving to make bristle adhere to tooth, thus cleaning teeth and slit.But there is this problem in this method: range of activity is limited in the oral cavity, and ordinary toothbrush is vertically brushed teeth and is difficult to brush than difficulty especially tooth inboard.In addition, this toothbrush can't prevent from laterally to brush teeth mistakenly.

The purpose of this utility model is that a kind of improved rotary electric toothbrush will be provided, and it can vertically not brushed teeth by the restriction of range of activity in the oral cavity relatively still, can also prevent from laterally to brush teeth mistakenly.

The purpose of this utility model is achieved in that the shape shell inner bottom part that turns of sealing stands up a batteries, battery top traverse motor, the driving shaft of motor has gear and reduction gearing to coincide, the low speed wheel core wheel and the power transmission shaft of reduction gearing are fixed, power transmission shaft is prismatic, and stretch out outside the shell, be with bar-shaped brush rod.The other end of brush rod is planted bristle.The outer switch control of shell power supply.Motor reduces revolution through reduction gearing, after going into overdrive, makes power transmission shaft drive bar-shaped brush rod around its axial line rotation, and brush rod need not vibrate in the oral cavity, and bristle just can adhere to toothbrush and vertically brush teeth.If laterally brush teeth, then brush rod is easy to come off from power transmission shaft, prevents from laterally to brush teeth mistakenly.

This utility model advantage: rotatablely moving of bar-shaped brush rod replaced the up-down vibration of ordinary toothbrush, so toothbrush static relatively can brushing teeth in the oral cavity solved the difficulty that scope little toothbrush in oral cavity is difficult to vibrate, can clean the toothbrush inboard easily with water.Can also prevent from laterally to brush teeth mistakenly.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Accompanying drawing is the profile according to the rotary electric toothbrush that the utility model proposes.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device comprises shell (4), the shell inner bottom part is standing up battery (5), motor (3) is disposed across battery (5) top, motor (3) driving shaft has gear and reduction gearing (6) to coincide, reduction gearing (6) low speed wheel core wheel and power transmission shaft (8) are fixing, and power transmission shaft (8) is prismatic, and stretch out outside the shell outer end, be with bar-shaped brush rod (2), plant bristle (1) around the other end of brush rod.Shell has switch (7) control power supply outward.

When energized, motor (3) drives bar-shaped brush rod (2) around its axial line rotation by reduction gearing (6) and power transmission shaft (8), bristle (1) can vertically be brushed teeth in the oral cavity, and the relative transfixion of brush rod has solved the range limited difficulty of oral cavity activity.Because brush rod is to be enclosed within on the power transmission shaft (8), so once laterally brush teeth, brush rod is easy to come off, and can prevent wrong method for brushing teeth.

This device can be improved on the basis of common electric shaver, can dual-use material.Promptly remove wire netting, blade, replace reduction gearing (6) and power transmission shaft (8).

Claims

Rotary electric toothbrush, relate to the device of brushing teeth, shape shell (4) the shell inner bottom part that turns of sealing is standing up battery (5), motor (3) is disposed across battery (5) top, it is characterized in that motor (3) driving shaft has gear and reduction gearing (6) to coincide, and reduction gearing (6) low speed wheel core wheel and power transmission shaft (8) are fixing, power transmission shaft (8) is prismatic, stretch out outside the shell outer end, is with bar-shaped brush rod (2), plants bristle (1) around the other end of brush rod.
