Description

The verticlly-brushing type electric toothbrush

Technical field this utility model relates to power-actuated cleaning or polishing device, particularly daily electric toothbrush.

The mode that its head toothbrushes great majority of the existing electric toothbrush of background technology adopt rotation to scrub, as Chinese patent CN 2412546, CN 2080343 disclosed technical schemes, they all utilize the rotary toothbrush head to come cleaning teeth.Also have the swing adopted to scrub the electric toothbrush (CN2154025Y) of mode, it adopts fork to stir the mode of head toothbrushes swing, and bristle swings back and forth with arching trajectory and reaches the effect of cleaning teeth.U.S. Pat 8778474 and US 5504958 disclosed electric toothbrushes, though adopted the mode of crank mechanism and single-row bristle swing, but because of each row's head toothbrushes is rotatably mounted on the axle, so single-row bristle is with arching trajectory swing cleaning teeth equally.And the teeth brushing way of science should be a bristle along the direction brush of teeth space, promptly perpendicular brush, and therefore, the requirement that the teeth brushing way of existing electric toothbrush is brushed teeth not in full conformity with science is difficult to reach and protects the purpose that tooth can effectively be removed dirt in the teeth space simultaneously again.

Utility model content the technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art part and provide a kind of bristles to do verticlly-brushing type electric toothbrush perpendicular to the straight reciprocating motion of brush length direction.

This utility model is taked following technical scheme: design a kind of verticlly-brushing type electric toothbrush, comprise: place the motor of toothbrush body inner chamber and the change-speed gearing group that drives by motor, the head toothbrushes that is installed in the vertical handle of toothbrush body and is arranged on this handle leading portion zone and flexibly connects with brush holder, the front of this head toothbrushes is fixed with bristles; The driven gear of described change-speed gearing group is provided with eccentric shaft, and this eccentric shaft converts rotatablely moving of described change-speed gearing group to round rectilinear motion that head toothbrushes drives pull bar by linkage; The back side of described head toothbrushes is provided with oblique square column and as the protruding key of the guiding of oblique square column base portion, described oblique square column is upward through the rectangle pilot hole of handle from the bottom, the oblique rectangle slotted eye that head toothbrushes drives rod head is stretched on its top, and the protruding key of described guiding is inserted in the rectangle pilot hole of handle; The width of the protruding key of described guiding is slightly less than the width of rectangle pilot hole, and its length adds that head toothbrushes verticlly-brushing type amplitude equals the length of rectangle pilot hole; The set screw that has a nut screw in downwards from the top of oblique rectangle slotted eye described oblique square column upper surface the gong hole, thereby realize that head toothbrushes, head toothbrushes drive pull bar and handle three's flexible connection.

When described motor is done to come and go rectilinear motion by change-speed gearing group and linkage drive head toothbrushes driving pull bar, the hole wall that head toothbrushes drives the oblique rectangle slotted eye of rod head will promote the oblique square column at the head toothbrushes back side, make head toothbrushes do reciprocating linear motion along the rectangle pilot hole of brush holder.

Described linkage comprises: connecting rod, union joint and pull rod shaft; Described connecting rod two ends are connected with the rearward end axle of eccentric shaft and union joint respectively; Fixedly connected with the rearward end that head toothbrushes drives pull bar with the leading section of union joint respectively in the two ends of described pull rod shaft.

In order to increase the degree of stability of head toothbrushes side-to-side vibrations, the protruding key of second guiding is set at the back side of described head toothbrushes, the second rectangle pilot hole of this second protruding key of guiding and handle is slidingly matched; The width of the protruding key of described second guiding is slightly less than the width of the second rectangle pilot hole, and its length adds that the amplitude of head toothbrushes side-to-side vibrations should be equal to or slightly less than the length of the second rectangle pilot hole.

The rectangle pilot hole of described handle and the length direction of the second rectangle pilot hole are vertical with the length direction of handle, thereby the direction of motion that guarantees head toothbrushes is vertical with the length direction of handle, realize perpendicular brush.

Compared with prior art, verticlly-brushing type electric toothbrush of the present utility model has following beneficial effect: when the head toothbrushes of electric toothbrush is put into the oral cavity of user naturally, the round linear movement direction of bristles is consistent with the direction of tooth seam, be that bristles is come backwash along the direction of tooth, therefore can not only effectively remove the dirt of dental surface and teeth space, damage tooth surface not meets the science method for brushing teeth that odontologist is recommended again.
