CN2164802Y - Motor-driven bidirectional toothbrush - Google Patents

Abstract

The utility model relates to a motor-driven bidirectional toothbrush. A toothbrush head is provided with two rotor brushes which are twisted by two metal wire clamp brushes or plastic rods clustered brushes. The toothbrush head can do rotation in opposite directions through a gear or a friction wheel drive by a miniature motor arranged in a hollow toothbrush handle. The toothbrush rotates longitudinally to the teeth. The toothbrush has the advantages of longitudinal brushing, scientific function, convenience and high durability.

Description

Motor-driven bidirectional toothbrush

This utility model belongs to the personal daily articles for use.

People are for oral hygiene, the permanent fine image that keeps the masticatory function of tooth and have one pair of pure white clean and tidy tooth, so the toothbrush of cleaning teeth has been arranged, current toothbrushes is the end at long handle shape sticking plaster, implant three to four row's bunch shape plastics silk bristles, with hand-held handle, make bunch shape bristle moving at the dental surface rider-type brush, reach the purpose of removing food detritus and dental surface dirt between teeth space.But the modern medicine scientific research shows, this traditional method for brushing teeth is science not very, and when back and forth brushing teeth, toothbrush has applied inside side force to tooth, influenced by side force, and easy year in and year out that tooth is occurred is loosening, makes antibacterial corrode gingiva generation periodontitis.Bristle is in the tooth surface side-friction, and the dental tissue at gingiva place is subjected to the bristle friction the most very, accumulates over a long period, and this method for brushing teeth influences the health and the health of tooth with regard to the groove mark that easily rubs out on the dental tissue at gingiva place.So the dentist warns people to keep tooth with correct, science, vertical method for brushing teeth.Current toothbrushes is because the custom that structural defective and tradition are brushed teeth is difficult for being adjusted into method for brushing teeth correct, science.

The purpose of this utility model is to overcome the defective of existing toothbrush and not enough and a kind of performance science voluntarily function of brushing teeth, the electric double-way toothbrush that can vertically scrub the tooth work automatically be provided.

The purpose of this utility model is to be achieved through the following technical solutions: settle micromachine and battery in the acrylic resin teeth brush holder of hollow, motor shaft drives the driving gear rotation of hollow pommel by extension shaft.Hollow plastic toothbrush pommel extends rectangular female cap shape head toothbrushes.Two each rotor brush or two rotor brushes of parallelization that are twisted into by two one metal wires folder bristle of parallelization in the brush by dense planting family shape bristle around the little sticking plaster, one end of rotor brush respectively have one can coaxial rotation gear, and making the engagement of two gears, the driving gear of one of them gear and driven by motor meshes.

Description of drawings:

Accompanying drawing one is the structural representation (front view) of electric double-way toothbrush

Accompanying drawing two is A-A ' face cutaway view Amplified images of figure one.

Accompanying drawing three is B-B ' face cutaway view Amplified images of figure one.

With reference to the accompanying drawings, in conjunction with the embodiments this utility model is described in further detail: a kind of electric double-way toothbrush, settle micromachine 2 in its hollow handle 1, battery 3 and in order to plug 4 to battery charge, driving gear 6 connects by extension shaft 5 and motor 2 rotating shafts.Two of head toothbrushes 7 interior pivot structure parallelizations press from both sides the stranded rotor of bristle by two one metal wires brushes 8,9(accompanying drawing two) gear 10 is fixed on the rotor brush 8, gear 11 is fixed on the rotor brush 9, gear 6,10,11 at grade, master gear 6 and gear 10 engagements, gear 8 and gear 11 engagements, connected on and off switch 12, motor 2 drives driving gear 6 rotations, 10 rotations of driving gear 6 driven gears, gear 10 driven gears 11 rotate, be fixed on the rotor brush 8 on the gear shaft, 9 as the rotation of accompanying drawing three directions of arrow, and the hairbrush of two relative direction rotations is scrubbed longitudinally to tooth in the oral cavity.Directly over head toothbrushes 7, open one and discharge seam 12, be convenient to the dirt under scrubbing on the tooth is discharged from seam.

Embodiment: hollow brush holder 1 and brush 7 be by the plastics integrated injection molding, and extension shaft 5 is made by copper wire, and gear 6, gear 10, gear 11 are by the engineering plastics injection mo(u)lding.

This utility model compared with prior art has following advantage:

1, science. owing to adopt rotor rotated brush in opposite directions, dental surface is only scrubbed longitudinally, conformed to mechanism cleaning of teeth.

2, convenient. adopt the electronic rotor brush rotation that makes, just can arbitrarily brush teeth as long as toothbrush is put into the oral cavity.

3, durable. when bristle damaged, as long as more exchanging rotor is brushed, toothbrush still can use repeatedly.

When implementing this utility model, also available friction pulley replaces gear, and the friction pulley processing technique is convenient and simple, and effect is effective equally.

Claims (1)

1, a kind of electric double-way toothbrush, form by hollow handle 1, head toothbrushes 7, micromachine 2, major axis 5, driving gear 2, gear 10,11, rotor brush 8,9, each is coaxial with gear 10,11 through major axis 5, driving gear 6 transmission intermeshed gear 10,11, rotor brush 8,9 to it is characterized in that micromachine 2, does to rotate in opposite directions with gear.
