Abstract

The utility model discloses a spring-loaded rotary toothbrush which is used in the daily tooth brushing. A pressing spring is arranged on the brush holder; gear wheels are arranged in the brush holder; the pressed pressure and the pressed elastic force of the pressing spring drive the gear wheels to make the brush shaft whose one end is enchased with toothbrush bristles rotate in positive and negative directions; the toothbrush bristles brush repeatedly from the top to the bottom along the tooth gaps, which can make the residue in the tooth gaps and the surface dirt thoroughly clean with great acting force within a short period of time; meanwhile, the brush cover can be disassembled, and the toothbrush bristles mounted different specifications of model number can be used as brushing and washing tools.

Description

Spring-loaded rotary toothbrush

The utility model is a kind of improvement to the 26S Proteasome Structure and Function of traditional toothbrush.

People carry out laterally in the inside and outside of tooth with traditional toothbrush or brush to move longitudinally and clean the teeth, and this toothbrush speed is slow, and active force is less, and horizontal sometimes brush is moving, then are difficult for the dirt in the teeth crevice is brushed clearly, and tooth can not be protected well.

The purpose of this utility model be design a kind ofly save time, laborsaving, economize the energy and the bigger positive and negative rotary tooth-brush that suppresses of cleaning function.

This rotary tooth-brush that suppresses is to be equipped with to suppress spring on toothbrush handles, suppresses the terminal transmission gear piece of spring and is meshed with the angular wheel of brush shaft end in the brush holder shell.Suppress the spring pressurized, the transmission gear piece drives bevel gear, and then the brush axle just rotates, and brush is moving up and down fast along teeth crevice for hairbrush.Suppress the elasticity that spring produces because of pressurized, drive the rotation of bevel gear rightabout again, rotated so the brush axle drives again round about, hairbrush is brushed round about along teeth crevice.Two sliding bearings separated by a distance of peace or rolling bearing in the brush holder bar shell make brush axle spin stabilization, speed up.Suppress the spring pressurized and speed up, the axially positive and negative two directions rotation of brush is also fast more.

The utility model has the advantages that suppress the spring pressurized, bristle can be both forward and reverse directions and brush up and down, need not use other energy along the slit direction of tooth, in the short time, with bigger active force with the thorough outwash of the dirt that accumulates thing and dental surface in the teeth crevice.

Accompanying drawing is the rotary tooth-brush that suppresses of the present utility model.

Fig. 1 is the front view that suppresses rotary tooth-brush.

Fig. 2 is the right view that suppresses interior transmission gear piece of rotary tooth-brush handle and bevel gear engagement.

Fig. 3 is the cutaway view of hairbrush.

The utility model (see figure 1) is pacified one and is suppressed spring 1 on brush handle shell, an end that suppresses spring is pressed into transmission gear piece 3, and the other end is fixed on the brush holder interior extremity with pivot pin 9.Transmission gear piece 3 (see figure 2) that is meshed with the angular wheel 4 of brush axle 6 ends, the brush axle passes the hollow handle bar, inlays the bristle (see figure 3) on its other end.There is hairbrush guard shield 8 hairbrush 7 outsides, and the hairbrush guard shield is embedded on brush holder bar shell 10 tops, and two rolling bearings separated by a distance 5 or sliding bearing 5 are set in the brush holder bar shell.Suppress the pressurized of spring and elastic force like this and make hairbrush 7 produce the both forward and reverse directions rotation, brush is moving repeatedly up and down along the teeth space crack for bristle, just can not consume other energy in the short period, with active force greatly with the thorough outwash of tooth.

The utility model also can take off the hairbrush guard shield, and brush end can be inlayed various model bristles, as the various brushing tool of scrubbing.
