Description

Practical electric toothbrush

This utility model belongs to articles for daily use, relates to a kind of practical electric toothbrush.

According to correct method for brushing teeth, the bristle of toothbrush should move towards crown from tooth root, so just can make the residue between tooth remove clean.But, in existing electric toothbrush technology scheme, the bristle of rotation only rotates towards a direction, therefore when using this electric toothbrush, its direction of rotation in the oral cavity only can make a certain side on or lower teeth be correct method for brushing teeth, other position has but formed bristle and has moved from crown towards the tooth root rightabout, is unfavorable for the cleaning and health care of this part tooth.In addition, the bristle of rotation is unfavorable to oral health with the oral soft tissue friction all the time in rotation process.

The purpose of this utility model provides a kind of practical electric toothbrush that bristle direction of rotation and bristle do not contact with oral soft tissue that changes.

The purpose of this utility model is achieved in that brush holder is provided with the DC micromotor commutation rotation gauge tap that band stops gear, and brush holder support is fixed with the arch shield cover that is positioned at brush one side.

Said shelves are covered with the bolster nest of brush head axis, and this nest engages with the spindle nose of brush head axis;

Said shelves cover inboard is provided with identical with the bristle contour shape, and the concave surface that is connected mutually with bristle ends.

Below with accompanying drawing and embodiment explanation this utility model.

Accompanying drawing 1 this utility model structure partial generalized section accompanying drawing 2 Figure 1A are to view accompanying drawing 3 gauge tap electrical connection graphs

Embodiment illustrated in fig. 1, be provided with minisize dc reducing motor and supplying cell in the brush holder 1, gear is to stop gear in the middle of the gauge tap 2 of control direction of motor rotation, and both sides are respectively to rotate and reverse gear, and brush holder is provided with its direction arrow.Gauge tap selects to have the middle double-pole switch that stops gear, and it is electrically connected schematic diagram and sees Fig. 3, and K switch both sides gear makes the motor D power supply opposite.

Brush holder support 3 ends are fixed on shelves cover 4 cambered surfaces that have as shown in Figure 1 of brush 6 one sides among Fig. 1, and the purpose of avoiding corner angle is to make it that comfort be arranged in the oral cavity.

Shelves cover 4 also is provided with the axle nest that supports brush head axis 5, and shelves cover 4 and brush head axis 5 support mutually, and both stability especially stability of brush is obviously improved, and favourable its rotation is smooth and easy.

The concave of shelves covers 4 inboards is identical with the bristle contour shape, and is connected mutually, its objective is that anti-stop cover inboard accumulates toothpaste or dirt, and bristle and the implication of concave surface linking are only to leave a little space mutually and can not contact.

When using this electric toothbrush according to brush in the position in oral cavity and the tooth position of brushing teeth, in good time conversion gauge tap gear can realize meeting the brush direction of rotation of correct method for brushing teeth.

The utlity model has the practicality of structure Xinjiang, can meet teeth brushing and not damage oral soft tissue Remarkable advantage.
