Description

Rotary disassembling toothbrush

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

The toothbrush of usefulness is made up of two parts usually now, be handle and head toothbrushes, they connect by one section slightly crooked linkage section, perhaps the negative and positive deck by part fixes (referring to the dismountable type toothbrush), plants on a long and narrow panel-shaped base body as this toothbrush first with a certain amount of synthetic fibers or animal mane and makes.Traditional toothbrush in use, be facing to tooth traditionally with the hair side of head toothbrushes, prolonging its orientation moves back and forth, because this method is unfavorable for removing the dirty thing between the tooth slot, impair the hygiene and health of tooth, oral cavity expert and doctor actively advocate the method for brushing teeth of employing science for this reason, and the direction of growth that toothbrush should prolonged tooth of promptly brushing teeth moves, and is prolonged and crown by tooth root.Brush tooth, toothbrush is brushed from top to bottom, the brush lower tooth, and toothbrush is brushed from lower to upper.Although this method is science very, limited by oral cavity space, difficulty is used in practical operation, brings some inconvenience to toothbrushing person, thereby has influenced popularizing of this scientific method.

The purpose of this utility model provides a kind of novel structure, the rotary toothbrush that shirks easy to use, with the promotion and application of the method for brushing teeth that advances science.

This utility model is realized with the following methods: the rotary toothbrush that shirks comprises three parts, and first's toothbrush handle includes power supply, motor and control device; Second portion is a fixed mount, and the box pin joint of its base, teeth groove cooperate with box pin joint, the teeth groove of toothbrush handle upper end to overlap mutually through the rotation box pin joint and identically reach interlocking both are connected as one; Third part is a head toothbrushes, and it directly is located at the fixed mount upper end.Power supply is connected with motor by switch, control device in the handle, the motor rotatory force is outwards transmitted by the power output shaft that is arranged in fixed mount centre hole of base hole, the transition axis that links to each other with power output shaft is connected with the head toothbrushes central shaft, thereby drive the rotation of head toothbrushes, head toothbrushes is a cylinder, certain way device fiber undercoat is pressed on its surface, and its rotation can be brushed teeth.During use, as long as the head toothbrushes axis is horizontal in the flank of tooth, make cylindrical toothbrush and the flank of tooth tangent, the rotating vector direction of selection head toothbrushes is consistent with the dental growth direction, presses required direction button, the energized rotation of can achieving one's goal.Steering control device and switch all are located in the toothbrush handle.In order to prevent that the friction of head toothbrushes and oral cavity wall from producing lost work and the oral cavity other parts are produced unnecessary damage, can around brush body, adorn half cylindrical shroud.This toothbrush is because brush is a rotation brush body, control direction in the time its direction of rotation be unidirectional successive, so when brushing teeth, as long as brush is faced toward the tooth position that to brush, power-on, but head toothbrushes is automatic teeth-brushing just, because motion is unidirectional, successive, so, it is very convenient that residue between slot dirt thing is removed, and need not to brush teeth with moving back and forth toothbrush handle down on hand, reduced because of toothbrush and moved in the oral cavity to the damage in oral cavity, also reduced the gingiva damage that is caused because of the dislocation of head toothbrushes and tooth, had easy to operate, characteristics such as useful gingiva and oral hygiene health.

The utility model is described in further detail below in conjunction with accompanying drawing.
