Abstract

The utility model relates to a teeth-cleaning brush, which changes the push and pull movement of a brush holder to a back and forth movement with the direction of motion of brush bristles perpendicular to the direction of motion of the brush holder, therefore, realizing people's purpose of vertical brushing of teeth by pushing and pulling the brush holder. The brush head of the teeth-cleaning brush is provided with a face piece 2 whose middle part is provided with a chute 10 and two bristle-planting boards 1 hinged with the face piece 2. The outer face of each bristle-planting board is provided with brush bristles 4, and the inner face of each bristle-planting board is provided with a slopingly arranged sliding slot 7. The T-shaped head 5 of a T-shaped opening and closing mechanism is arranged in a chute 10 whose both sides are respectively provided with a drawing claw 6 matching with the sliding slot 7. A T-shaped rod 8 forms a slide fit with a round hole 11, and is screw jointed with a brush holder 9. By pushing and pulling the brush holder 9, the T-shaped head 5 can slide in the chute 10, and the brush bristles carry out vertical motion, realizing the purpose of vertical brushing.

Description

Teeth-cleaning brush

The utility model relates to toothbrush, the especially a kind of bristle motion direction and the brush holder direction of motion perpendicular easily to dental prophylactic bruss.

Brushing teeth is the fundamental method of maintaining teeth, and it helps to brush swill and dental plaque on the tooth.Perpendicular brush method is the method for brushing teeth of advocating in recent years, and it can more effectively keep tooth hygiene.But therefore the cross-brushing method of " Dragsaw type " about people get used to, uses traditional toothbrush to be difficult to promote the perpendicular brush method of comparison science.

The purpose of this utility model provides a kind of easily to Tooth-cleaning toothbrush, use this toothbrush, people can be become the bristle back and forth movement vertical with the brush holder direction of motion to the push-and-pull campaign of brush holder, be that people use customary way push-and-pull brush holder, can make bristle along the vertical back and forth movement of tooth, reach the purpose of perpendicular brush.

The utility model is achieved in that easily and comprises brush and brush holder to dental prophylactic bruss.Brush comprises face-piece, carries hair plates and mechanism for opening/closing.There is one the one dark skewed slot of the shallow end of end at the middle part of face-piece inboard.Planting hair plates has two, hinged with the left and right sides of face-piece respectively.Plant the hair plates outside bristle is housed, inner face has the chute of an oblique setting.Mechanism for opening/closing is a T type slide block, and the T connector of T type slide block is placed in the skewed slot of face-piece, and the circular hole of the T type bar of T type slide block and face-piece one end is and is slidingly matched.T connector a pulling claw each side arranged, pulling claw inserts and plants in the chute of hair plates inner face.Brush holder and T type bar are by being threaded.

During use, brush is placed on and gently is pressed on tooth in the mouth, when promoting brush holder, T connector moves to the superficial part of skewed slot from the deep of face-piece skewed slot, plant hair plates and be converted to opening by closure state this moment two, and bristle is done the motion of brushing teeth from inside to outside, when the pulling brush holder, T connector is from the shallow depths of getting back to of face-piece skewed slot, and pulling claw is planted hair plates with two and closed up by planting chute tilting on the hair plates, and bristle is done the motion of brushing teeth of ecto-entad.Along with the continuous push-and-pull of brush holder, the bristle conversion direction of motion constantly along flat tooth vertical motion, thereby reaches perpendicular brush purpose.
