Description

Electronic rotary toothbrush

This utility model relates to the tooth hygiene articles for use, particularly a kind of electronic rotary toothbrush.

People are when sooner or later brushing teeth at present, and the toothbrush of use all is manual toothbrushs.People grasp handle when brushing teeth, and brush is stretched in the mouth, and bristle contact tooth with pulling moving brush holder side-to-side movement, makes bristle at tooth top left right motion then.The shortcoming one of this toothbrush is that to want staff to pull at moving, the 2nd, and bristle can not be removed totally the dirt in the tooth crack at tooth top left right motion, and it is unfavorable that cleaning is taken care of one's teeth.

The purpose of this utility model is exactly will provide a kind of bristle with the driven by motor brush to rotate at the tooth top and brush holder can separate with brush, the renewable metathetical electronic rotary toothbrush of brush.

This utility model is to realize like this, it is to load onto a joint aneroid battery in brush holder, dc motor and reducing gear, in brush, adorn a hollow cylinder, arrange on the cylinder and load onto the wave bristle, in the hollow cylinder of brush, adorn one then and connect rotating shaft, and be connected brush and brush holder in aggregates by this rotating shaft.Press the button during work, energized, the motor in the brush holder rotates, drive the big pinion rotation of reducing gear, the rotating shaft of gear wheel drives again and connects rotating shaft and rotate, and connects rotating shaft and drives hollow cylinder and bristle rotation in the brush again, and the direction of rotation of bristle can just can be anti-.After toothbrush used a period of time, when bristle damaged, at this moment, we loaded onto new rotating shaft and brush as long as change the brush that connects rotating shaft and damage from brush holder.

This utility model has been realized brushing teeth electronic, and bristle can rotate, and it was both convenient and practical, and cost is saved in the separable renewal displacement of brush and brush holder, helps the health hygienic of tooth again, and its appearance provides a kind of ideal electronic rotary toothbrush for people.

Below in conjunction with accompanying drawing most preferred embodiment is described.

Accompanying drawing 1 is this practical new construction sketch map.

With reference to accompanying drawing 1, the handle of brush holder (9) is as cylindrical, two ends are hemispherical, one hollow long handle is arranged on the hemispherical of upper end, brush holder (9) inside is hollow, battery (11) is loaded onto in the left side in brush holder (9) is hollow, micromotor (10) is loaded onto on the right side, a gear reduction (7) is adorned in top at battery (11) and micromotor (10), the output revolving shaft of micromotor (10) and the pinion rotating shaft on the reducing gear are connected, a triangle deep hole is left in reducing gear gear wheel and pinion interlock, the axle head of the output revolving shaft of gear wheel.Adorn a positive turn-off at the left-external side of brush holder and close (12) and reversal switch (13), and with lead (14), with the circuit communication of switch (12), (13), battery (11), micromotor (10).The top of brush (1) has one] the type opening, the bottom is a long cylinder, a water proof packing ring (15) is adorned in the middle part of having in its perforation of perforation in the long cylinder center, bristle (3) is wavy, be fixed on by rows on the plastic cylinder (4), plastic cylinder (4) axle center has a perforation, it is placed on brush] in the type opening, connect rotating shaft (5) upper end and pass the perforation in the long cylinder of brush and the axle center hole of the plastic cylinder (4) in the brush (1), be contained in the bearing (2) of brush, connecting rotating shaft (5) can rotate the plastic cylinder (4) of band bristle in the long cylinder perforation of brush, then be to be fixed on to connect in the rotating shaft (5), and can rotate with connecting rotating shaft (5).The lower end that connects rotating shaft (5) is triangular in shape for one section, and it passes hollow long of brush holder and inserts in the triangle deep hole of reducing gear gear wheel rotating shaft end, thereby makes brush (1), and brush holder (9) becomes a complete toothbrush.Extract in the axle head triangle deep hole of gear wheel rotating shaft the lower end that will connect rotating shaft (5), then connect rotating shaft (5) and be with brush (1) to separate with brush holder, and replaceable new brush (1) be connected rotating shaft (5).
