Abstract

An electric toothbrush being able to brush tooth toward the tooth growth direction. a direct current power supply, a double pole three-throw switch, and a small-sized DC motor are electrically connected in order in an insulated casing, namely a base frame, in addition, a slack-off gear cluster, a bearing rod ,a transmission rod, a toothbrush head, a toothbrush head cover also need to be installed. A cylinder for loading the toothbrush bristles is installed in the middle of the toothbrush head, and the toothbrush bristles are adhered around the cylinder presenting a radiating shape and are vertical to the cylinder surface. The toothbrush head is suited on the transmission rod tail end. When the double pole three-throw switch is placed one end, the electric motor provides electricity to revolve and drives the gear cluster, the transmission rod and the toothbrush head to revolve. The toothbrush head revolves along its central axis, and can brush tooth toward one direction; When the double pole three-throw switch is placed the other end, the output electrode is opposite to the first condition, and the electric motor revolves in an opposite direction and drives the toothbrush head to brush tooth toward another direction; When the double pole three-throw switch placed in the middle closed position, the electric pressure cannot be output, and the electric toothbrush shuts off.

Description

Electric toothbrush

Technical field this utility model relates to a kind of electronic tooth brushing device, especially the tooth brushing device that can brush teeth along the dental growth direction.

Background technology is present, and the head toothbrushes of the electric toothbrush on the market is to stretch out bristle to same direction from disk shape substrate, and during use, substrate is a fulcrum with himself center, along himself plane rotation, drives bristle and grinds tooth.But can not brush teeth along the direction of growth of tooth.The product that also has has more one and moves reciprocatingly or the reciprocating substrate of arc along himself plane, also can only back and forth brush teeth back and forth, can not brush teeth to a direction along the direction of growth of tooth.The method for brushing teeth of science should be " upper tooth is down brushed, and lower tooth is up brushed ".Above-mentioned electric toothbrush can not science brush teeth, life-time service can damage gingiva.

Summary of the invention is in order to overcome the deficiency that existing electric toothbrush can not be brushed teeth along the dental growth direction, this utility model provides a kind of electric toothbrush, this electric toothbrush is not only time saving and energy saving, and is to use the method for " upper tooth is down brushed, and lower tooth is up brushed " to brush teeth.

The scheme that its technical problem that solves this utility model adopts is: in insulation crust is held concurrently pedestal, dc source, double-pole three are put switch, small-sized DC motor is electrically connected in proper order, need to install slack-off gear train, support bar in addition, drive link, head toothbrushes are fixed on the end of drive link.

Support bar hollow, an end be fixed on the pedestal and opening in pedestal, remainder stretches out pedestal, can stretch into the oral cavity.The center allows drive link pass, and drive link can freely rotate therein.Support bar is installed the toothbrush head-shield away from the end of pedestal.

Drive link is carefully cylindrical, pass support bar, expose two ends, end in pedestal is fixed a bigger gear, be meshed than pinion with fixed on the miniature motor, other end top central punch is made female thread, puts behind the brush to screw in a screw, fixedly head toothbrushes advises that fixedly the part of brush is done squarely.Less direct geared is fixed on the rotor of output shaft axle of miniature motor.

Is the cylinder of carrying bristles in the middle of the head toothbrushes, cylinder diameter should be 0.6---between 0.8 centimetre, height is 2.5---between 3.5 centimetres.Bristles is radially attached to around cylindrical, and perpendicular to periphery, bristles length should be 0.7---between 0.8 centimetre.The hole is done at the cylinder center, and square hole is made in suggestion, is enclosed within the end of drive link, and can takes off.In order to overcome the hypotrichous deficiency of toothbrush, bristles can adopt bifurcated configurations, and promptly base portion is one, up is divided into two, is further divided into four.

The main body of toothbrush head-shield is an arc, is fixed on the end of support bar, the side of head toothbrushes, is parallel to the axle of head toothbrushes, masks the part brush from the side.To stop that bristle brushes face and tongue.

Double-pole three is put each two contact of switch ends and is adopted oppositely electrical connection, and selects the one end as power input or outfan, and middle two contacts are outfan or input.

Situation one: when double-pole three was put switch and placed an end, the motor power supply was rotated, and driven gear group, drive link, head toothbrushes rotate, and can brush teeth to a direction; Situation two: when double-pole three was put switch and placed the other end, output electrode was opposite with situation one, and the motor backward rotation drives brush and brushes teeth to another direction; Situation three: double-pole three put switch place in the middle of during the room, output voltage not, electric toothbrush is closed.

The beneficial effects of the utility model are: can use the scientific method of " upper tooth is down brushed, and lower tooth is up brushed " than in time saving and energy saving with traditional toothbrush.

Description of drawings further specifies this utility model below in conjunction with drawings and Examples.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the structural relation figure of main machine components of the present utility model.

Fig. 3 is the A of Fig. 2---the support bar of A cutaway view, drive link, toothbrush head-shield, head portion.

Fig. 4 is an embodiment vertical section structural map of electric toothbrush.

Among the figure, 1. miniature motor, 2. large gear, 3. miniature gear, 4. drive link, 5. support bar, 6. head toothbrushes, 7. toothbrush head-shield, 8. set of cells, the 9 shells pedestal of holding concurrently, 10. double-pole three is put switch, 11 battery hatch.

The specific embodiment is in Fig. 1, and set of cells (8) adopts tandem-type connection, and the output both positive and negative polarity is put switch (10) input with double-pole three respectively and is electrically connected, and double-pole three is put switch (10) outfan and exported two path electrodes and the electrical connection of miniature motor (1) input.Micro-machine (1) should adopt powerful model.

In the embodiment shown in fig. 4, set of cells (8) adopts No. 5 battery series connection of 3 joints, contacts parallel placement (replacing with a batteries among the figure) in twos.Double-pole three is put switch (10) handle and is exposed at hold concurrently pedestal (9) outside of shell, and remainder is hidden in shell pedestal (9) inside of holding concurrently, and battery hatch (11) is arranged on a side of set of cells (8), and is close and parallel with wherein two batteries.The large gear of slack-off gear train (2) adopts internal gear, and miniature gear (3) is meshed with it at large gear (2) inward flange.
