Abstract

The utility model discloses an electric motor brush that brush feather is vertical with brush handle when rotation, a metal rod with one end connected with a coupler and the other end bent to form Z-shaped is used as a driving rod, a brush head matched with pin is provided with a long narrow slot, the Z-shaped head of the driving rod is extended into the long narrow slot, when the driving rod is rotated, the Z-shaped head is to be matched with the long narrow slot so as to drive the brush to sway along the pin to and fro, thereby realizing the purpose of brushing teeth. Compared with the prior art, the utility model simplifies the driving mechanism greatly so as to reduce the cost and assembly difficulty.

Description

A kind of rotary electric toothbrush

This utility model relates to the daily life instrument, particularly a kind of rotary electric toothbrush.

The toothbrush that uses in the daily life is made up of bristle and brush holder, bristle is fixed on an end of brush holder, this toothbrush with low cost, easy to use makes people always get used to horizontal brush, but science proves horizontal brush and can't remove the residue in the teeth space, goes down just to cause the formation of various odontopathies for a long time.In order to address this problem, a kind of rotary electric toothbrush that rotates along teeth space has been proposed, be that bristle changes around brush holder, this toothbrush has thoroughly changed the bad habit of horizontal brush, can remove the residue in the teeth space, but when the bristle of toothbrush turns to the root of the tooth position, to damage root of the tooth unavoidably, simultaneously must install guard shield additional in the one side of colliding with epipharynx, otherwise injure epipharynx, besides the residue of teeth space depths still can't thoroughly clean, and all-in-one-piece brush brush holder structure can't be utilized brush holder again and caused waste.Thereby can rotate the toothbrush of thoroughly removing teeth space depths residue by vertical brush holder so proposed a kind of bristle again, but in order to realize that the vertical brush holder of bristle rotates, gear has all been adopted in these designs, the drive mechanism that tooth bar etc. are complicated, like this, cost is very high, complex structure, the assembling maintenance difficult.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, and cost reduces greatly, the electric toothbrush that the interconvertible bristle of brush rotates perpendicular to brush holder.

Implementation of the present utility model is:

The motor of dry cell power supply, switch keying is housed in the chamber of being made up of brush holder, brush holder support, the output shaft of motor is connected by shaft coupling with drive link, first brush and brush holder support pass through cottered joint, first brush is column type, the axis of first brush is vertical with the drive link pivot center, one end bending of drive link is Z-shaped, and stretches in the vertical slot that the first brush sidewall opened.Brush holder and brush holder support are dismountable socket connections.There is more than one projection to stretch on the brush holder in the corresponding groove on the face of first brush with respect to bristle.The position of adjacent first brush is equipped with second brush on brush holder support.

This rotary electric toothbrush is compared with existing rotary electric toothbrush, and drive mechanism has been save structures such as gear, and substitutes with a drive link, and is simple in structure, realized that inexpensively brush rotates perpendicular to brush holder.And brush holder can change the outfit.

Below in conjunction with drawings and Examples implementation of the present utility model is described further.

Fig. 1: this utility model cross-sectional schematic.

Fig. 2: A enlarged drawing among Fig. 1

Fig. 3: the first brush sketch map

The brush holder 2 of rotary electric toothbrush and brush holder support 9 mutual socket connections, brush holder 2 tail ends are pressed into back shroud 1,1 joint 1.5V aneroid battery 3 and motor 5 is housed in their chamber, switch 6 is equipped with in the outside, the three is electrically connected with the metallic conduction sheet, motor 5 is fixed on brush holder 2 inner chambers by interior cover 16 and inner casing cover 4, and interior cover 16 and inner casing cover 4 and brush holder 2 inner chamber close-fittings play the water proof and dust proof effect to motor 5 and battery 3.

The output shaft of motor 5 is connected by shaft coupling 7 with drive link 8, and drive link 8 is made by an elongated metallic rod, and one end and shaft coupling are connected, and the other end bends to Z-shaped and extend in the elongate slot of opening on first brush 11 12.

Have the groove 12 of long and narrow on first brush 11, the width of groove 12 and drive link 8 matched in clearance.

Respectively there is a projection on corresponding both sides of going up near groove 12 of first brush 11 and bristle, be deep in the groove corresponding on the brush holder support 9, thereby first brush 11 is restricted around the amplitude peak that pin 10 rotates.

Position near first brush 11 has also clamped fixed second brush 13 on brush holder support 9.

After motor 5 starts, driving drive link 8 rotates, the Z font end of drive link 8 is deep in the groove 12 of first brush 11 and with it and cooperates, and then Z font end just drives first brush 11 and swings back and forth around pin 10 when rotate in the axle center of drive link 8, and the amplitude of swing is by the size decision of Z font.Like this, just played the effect of cleaning teeth.

Second brush of being installed near first brush 11 13 can play the effect that improves mouthfeel when brushing teeth.

Sealing ring 14 is installed in brush holder support 9, and anti-sealing enters motor, also has leaking hole 15 on the brush holder support 9.
