Abstract

A swing type electric toothbrush is composed of a handle, a battery, a motor, an eccentric wheel, an eccentric pin, a swing arm, a pin shaft, a brush head and a power switch. After the power is switched on, the motor drives the eccentric wheel and the eccentric pin to rotate, and the eccentric pin drives the swing arm and the brush head to swing, so that the tooth brushing action is completed. The power source of the toothbrush can be an elastic spring or an inertia idler wheel instead of a battery or a motor.

Description

The swing type electric toothbrush

This utility model relates to a kind of electric toothbrush.

At present, known electric toothbrush brush bundle rotates, and with the bristle of rotation tooth is cleaned out.But the brush of this electric toothbrush is special, and cost is higher, and the swing up and down mode of the rotary movement of bristle during with manual brushes is different fully, and it is very uncomfortable that user is felt.

The purpose of this utility model is to provide a kind of swing type electric toothbrush of cheapness, and its brush swings up and down, and is identical with the motion mode of manual brushes.The front end of ordinary toothbrush intercepted just can be contained in this utility model brush of being taken in and use, the source of brush is wide, and cost is low.

The purpose of this utility model is achieved in that in the handle of electric toothbrush on and off switch, battery and motor is housed, motor shaft end is equipped with eccentric and eccentric pin, pin inserts the chute string of swing arm rear end, and the front end of swing arm is an axial deep hole, and swing arm and handle are hinged by bearing pin.Insert brush in the deep hole of swing arm front end.Behind the energized switch, the motor rotation, the pin on the eccentric cooperates with the chute of swing arm rear end and the bearing pin at swing arm middle part, and will rotatablely move is converted to swing, swing arm drives brush and swings up and down, and user leans against brush on the tooth can finish the action of brushing teeth.

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is the sectional side elevation of embodiment 1.

Among the figure: 1. handle, 2. battery, 3. motor, 4. eccentric, 5. eccentric pin, 6. swing arm, 7. bearing pin, 8. brush, 9. switch.

Fig. 2 is the sectional side elevation of embodiment 2.Adopt elastic clockwork spring as power source.

Among the figure: 1. handle, 4. eccentric, 5. eccentric pin, 6. swing arm, 7. bearing pin, 9. brush, 10. elastic clockwork spring.

Fig. 3 is the sectional side elevation of embodiment 3.Adopt the inertia idle pulley as power source.

Among the figure: 1. handle, 4. eccentric, 5. eccentric pin, 6. swing arm, 7. bearing pin, 8. brush, 11. inertia idle pulleys.

In the example 1, battery gives motor 3 power supplies by switch 9, and motor 3 drives eccentric 4 and eccentric pin 5 rotations.Because eccentric pin 5 has inserted in the chute of swing arm 6, swing arm 6 is hinged on the handle 1 by bearing pin 7 can only do swing, and the eccentric pin 5 of rotation drives swing arm 6 swings, and 6 of swing arms drive brush 8 and finish the action of brushing teeth.

In the example 2, elastic clockwork spring 10 drives eccentrics 4 and eccentric pin 5 rotations, and drives swing arm 6 and brush 7 swings up and down, and finishes the action of brushing teeth.

In the example 3, inertia idle pulley 11 drives eccentrics 4 and eccentric pin 5 rotations, and drives swing arm 6 and brush 7 swings up and down, and finishes the action of brushing teeth.
