Abstract

The utility model relates to an automatic toothbrush, which improves the driving structure of the general complicated gears, crankshafts, levers, etc. Thus, the automatic tooth brush reduces the resistance of the mechanical drive, prevents the toothbrush from stopping because of the resistance of the mouth cavity and the teeth; the rotation of the counterweight block is driven by the micro motor; under the function of the centrifugal force, the motor body and the toothbrush resonate. As the brush surface is contacted with the tooth surfaces, and the vibration along two directions of the brush surface and the brush back disappears or is shifted into sway at both sides under the function of elasticity; thus the sway at both sides is more violent. The utility model has the advantages of simple structure, easy fabrication and long service life.

Description

Sway type automatic toothbrush

This utility model relates to a kind of electric toothbrush.

Brushing teeth is the thing that people will do every day, and the teeth brushing way of the best is along the perpendicular up and down brush of teeth space, brushes traditionally but erect up and down, firmly goes up and is difficult to grasp, and it is convenient and strength-saving to be not so good as parallel push-and-pull.It is rotary as (CN88210165) and crank type (CN86201907) that existing electric toothbrush mostly is, though they can finish the function of perpendicular brush up and down, but exist toothbrush and be subjected to the resistance of oral cavity, tooth and vexed car phenomenon, and in mechanical bent axle transmission process, the useful work loss is excessive, shortcomings such as useless electricity.

The present utility model a kind of runout formula automatic tooth-brush, abolished the drive mechanism such as gear, bent axle, Bars bar of conventional complexity, thereby reduced the machine driving resistance, avoided toothbrush to be subjected to the resistance of oral cavity, tooth and shortcomings such as vexed car.

Of the present utility model being contemplated that: with the rotation of minitype motor driving eccentric weight, under action of centrifugal force, make body produce resonance together with toothbrush, because brush finish contact facing, the vibration of the brush finish brush back of the body two aspects, disappearing in the elastic reaction of brush holder translates into the both sides runout, makes the both sides runout more strong, and its characteristic structure is simple, easy to manufacture, the life-span is long.

Fig. 2 is a utility model A face cutaway view.

Fig. 3 is a utility model toothbrush cutaway view.

This utility model is made up of toothbrush (1), casing drive end bearing bracket (2), casing (5), motor (10), battery (12), press button (7), bonnet (15), eccentric weight (3), rubber waterproof cover (6) etc., its toothbrush (1) is rectangular wedge shape, be inserted in the oblong aperture of front cover (2), cooperation is seated by the inclined-plane, both sides, its gradient is 1:20, and inboard the tightening with both ends of the surface for fine thread and casing (5) of front cover (2) depends on the jail to seal.Press button (7) is to finish projection by mould when the injection moulding of casing (5), and natural rubber bucker (6) is tight encases press button (7).Press rubber waterproof cover (6), button (7) overcomes the elastic force of spring (8), makes contact (9) contact structure energize loop with motor (10).Contact (9) extends to the afterbody of casing (5), contact with the internal ring (14) of bonnet (15) by elasticity, spring (13) is fixed on the inner face of internal ring (14), when the afterbody of bonnet (15) with fine thread and casing (5) revolves by after sealing, spring (1) is compressed on the negative pole of battery (12), formation conducts the loop, and battery (12) is changed by bonnet.Motor (10) is packed into by casing drive end bearing bracket (2), in casing (5), makes motor not have rotation by the salient point in the casing (5) and the flat location of rubber bushing (11) by rubber bushing (11) liner.The axial location of motor (10) is to push down the motor casing front end face after tightened by drive end bearing bracket (2) with locating snap ring (4), and it is moving to make motor (10) axially not have string.The axle of motor (10) is gone up the eccentric weight (3) that the dress hard lead is made.Holding tail during use presses the button, the rotation of driven by motor eccentric weight, under action of centrifugal force, casing and toothbrush produce resonance thereupon, brush finish and brush back of the body both direction also have same vibration in resonance, because brush finish contacts facing and holds under a little grip of machine handle, transfer to the both sides of toothbrush by the elastic reaction disappearance of brush holder, and then make the runout of both sides more strong.

The utility model has changed the wrong teeth brushing way of Manual parallel push-and-pull and the uncomfortable property of manually erecting up and down brush up hill and dale, abolished the kind of drive such as gear, bent axle, Bars bar of conventional complexity, thereby reduced the useful work loss that causes because of machine driving, avoided toothbrush to be subjected to the resistance of oral cavity, tooth and vexed car phenomenon takes place.

Claims

1, a kind of runout formula automatic tooth-brush of being made up of toothbrush (1), casing drive end bearing bracket (2), casing (5), motor (10), battery (12), press button (7), bonnet (15) etc. is characterized in that:

On the axle of motor (10) metal eccentric weight (3) is housed.

2, runout formula automatic tooth-brush according to claim 1 is characterized in that: toothbrush (1) cooperates for the interior inclined-plane of oblong aperture that microscler wedge shape is inserted into casing drive end bearing bracket (2).

3, runout formula automatic tooth-brush according to claim 1 and 2 is characterized in that: inboard the tightening with both ends of the surface for fine thread and casing (5) of casing drive end bearing bracket (2) depends on the jail to seal, and rubber waterproof cover (6) is tight encases press button (7).
