Abstract

The utility model discloses an electric toothbrush device which can be conveniently used for vertically brushing teeth, which is a scientific mode for brushing teeth. The electric toothbrush of the utility model is composed of a handle, a cylindrical brush, a protective cover, a micro motor, etc. The utility model is characterized in that the micro motor is connected with a speed reducer connected with the cylindrical brush; the position where the brush is positioned is provided with the protective cover which is used for supporting the brush and separating the brush from the muscle at the part which is corresponding to teeth, which can eliminate uncomfortableness; the extending part of the protective cover and the extending part of the outer shell of the speed reducer are mutually inserted. The brush can rotate along a positive direction or a reverse direction, which is realized by the micro motor controlled by a switch.

Description

Electric health-care toothbrush

This utility model relates to a kind of electric tooth brushing device, particularly can realize easily in the mode of rotating brushes tooth is erected brush.

According to modern stomatology research, the method for brushing teeth of science should be that tooth is erected brush, and horizontal brush is unscientific, and the perpendicular brush of current toothbrushes is extremely inconvenient.

For addressing this problem, Chinese patent application 89211808.3 provides a kind of " electronic health toothbrush " directly drives the hairbrush rotation to reach the purpose of perpendicular brush with a small and special electric machine.But it is investigated interrelated data as can be known the rotating speed of small and special electric machine generally at 3000-5000 rev/min, the hairbrush of such rotating speed is put into mouth, people are difficult to adapt to, this patent application has also proposed to be provided with a resistance and has come reduction of speed in circuit for this reason, but the power of battery is certain, add the power that a resistance just equals to reduce micro machine, though speed can lower like this, but the original very little moment of torsion of micro machine also will reduce, when hairbrush and tooth contact zones load, might not reach the purpose of brushing teeth because of the too small stall of moment of torsion.Its tooth sap cavity also is unnecessary in addition, because of now also having tooth liquid, market can not supply, and inconvenient.

Task of the present utility model provides a kind of improved electric toothbrush device, and it not only can realize perpendicular brush, and can drop to the degree that people can adapt to the rotating speed of hairbrush, does not reduce the power of micro machine again.

Task of the present utility model is achieved in that in the micro machine front of electric toothbrush and connects a decelerator that the output shaft of decelerator is connected with cylindrical brush again, thereby the rotating speed of hairbrush is reduced.

Below with reference to accompanying drawing this utility model is described in further detail.

Fig. 1 is a structural principle sketch map of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Cylindrical plastic hairbrush (1) with reference to a center of Fig. 1 band metal shaft (2) is supported in the protective cover (3) and can be used for brushing teeth by forward or reverse.Protective cover (3) is made with plastics, semicircular in shape, socket of its extension band is used for and peg graft in the extension of reducer shell (21), its main effect is that support cylinder shape hairbrush (1) and the muscle that makes the relative part with tooth of hairbrush (1) separate in order to avoid hairbrush and muscle friction produce incompatible, more than be hairbrush protective cover part, this part can regularly replace.Handle (20) is a shell made from plastics, the inside is provided with battery cavities battery (12) is housed, (13) power supply, the micro machine chamber, micro machine (19) is placed in one and is fixing, the place is provided with switch (11) in the micro machine chamber, being right after the micro machine chamber is decelerator, decelerator is by shell (21) and gear (7), (8), (9), (10) composition such as, gear (9) is fixed on the projecting shaft of micro machine (19), gear (8), (7) be separately fixed on the axle (6), gear (10) is fixed on the output shaft (5), gear (9) and gear (8) engagement, gear (10) and gear (7) engagement, decelerator shell (21) and handle (20) connect together with bonding or screw, socket of the extension band of decelerator shell (21) links to each other in order to the socket with protective cover (3), the output shaft of decelerator (5) is connected by the axle (2) of plastic connector (4) and cylindrical brush, is realized the rotating of hairbrush (1) by switch (11) control.Loam cake (22) plays the cleaning protective effect, has electrode (15), (16) and electrode (17), (18) to be connected battery (12), (13) power supply in the battery cavities.(14) be the battery cavities lid.

Claims

1, a kind of electric health-care toothbrush device, by handle (20), (3) and micro machine compositions such as (19) are put in cylindrical brush (1), protection, it is characterized in that micro machine links to each other with a decelerator, and the output shaft of decelerator (5) is connected with cylindrical brush axle (2) again.

2, it is characterized in that by the described electric health-care toothbrush device of claim 1 axle (2) at cylindrical brush (1) two ends all is supported on the protective cover (3).
