Description

Caterpillar type toothbrush

The crawler type toothbrush is a kind of apparatus of cleaning teeth, can use in human daily life.Its international Patent classificating number is A61C17/16(5).

Toothbrush is the most typical with ordinary toothbrush and electric toothbrush.The bristle of ordinary toothbrush is put on hard brush body, and the hand-held brush holder of people carries out cleaning teeth.Electric toothbrush is a kind of cleans tooth with water for the external bristle of cylindric hard brush body is rotated by motor-driven, and the bristle of its contact tooth is few.Another kind is put to be driven in rotation on gear for each bunch bristle is perpendicular and is cleaned tooth with water, and it can not be cleaned with water along tooth root cuspad.Also have a kind of put on hard brush body, to move back and forth for bristle brush teeth.Ordinary toothbrush and electric toothbrush have good function and advantage separately, and are still being used widely.But also there is shortcoming separately in they, and what have can not automatic teeth-brushing, and what have cleans direction with water and can not be undertaken by the root of the tooth cuspad, and the few efficient of the bristle of the contact tooth that has is low.

Be to propose a kind of new design the order of this utility model research, bristle can be put on soft brush body, make the more contact tooth of bristle, clean with water along the root of the tooth cuspad automatically, raise the efficiency, can keep healthy to gingival massage simultaneously.

The technical characterictic of crawler type toothbrush is that its whole mechanism comprises four parts.Crawler type brushing machine, housing, driving mechanism and Switching Power Supply mechanism are arranged.The brush body 4 of crawler type brushing machine for the tubular software, outward have bristle 5, in bulge loop formula track arranged, be arranged on driving shaft 2 and the servo axis 3, and be supported for the crawler belt shape and can roll, driving shaft 2 and servo axis 3 have key, are arranged on housing 1 top for the uniform axial raised line of thick portion external diameter, the lower end of cylinder, axle 2, and support 9 is inserted in axle 2 and 3 external diameters for axis hole is arranged at flat-shaped body, top, the bottom is flat drum shape and is enclosed within housing 1 top external diameter.The middle part of housing 1 is that how much shapes, bottoms are cylinder-like body, and its internal diameter has ring groove and rib-loop.Driving mechanism is by turbine 6,7, side cover 8, motor 13 compositions such as grade, turbine 7 internal diameters have key, be arranged on driving shaft 2 lower ends, turbine 6 has and 7 scroll bars that mesh for the right side, there is axis body at two ends, be arranged in the housing 1, side cover 8 is the plate body that a side has axis hole, be arranged on the housing 1, motor 13 is arranged in the housing 1 fixing by ring 14, scroll bar and turbine 6 engagements are arranged on the arbor, and drive turbine 7 by the scroll bar on 6 right sides and drive driving shafts 2 and rotate, driving brush body by axle 2 rolls, the switch 11 of Switching Power Supply mechanism is 4 groups of contact double-throw formula switches, be arranged on housing 1 side, be connected with power supply with motor by lead, control motor forward or reverse, waterproof membrane 12 is soft book membranous body, be arranged on switch 11 and housing 1 surface, dividing plate 15 is discoideus body, be arranged on housing 1 bottom internal diameter, anodal 16 is plates, be arranged on a side of dividing plate 15, tail shell 17 is a cylinder-like body, the top external diameter has rib-loop, built-in negative pole turriform spring 18, be arranged on housing 1 bottom.

Advantage of the present utility model:

The crawler type toothbrush can make the more softish contact tooth of bristle, brushes teeth along the root of the tooth cuspad automatically, clean with water thoroughly, and high efficiency, simultaneously to the gingival massage health care, the interchangeable health of brush body, small and exquisite power saving, easy to use.
