Abstract

The utility model discloses a toothbrush device for cleaning teeth, which comprises a plastic outer shell, a miniature motor, an output shaft, a toothbrush head, a set of gear mechanism and a crank-rocker mechanism, wherein, rotary motion outputted by the miniature motor drives the output shaft to have reciprocating rotary motion through the gear mechanism and the crank-rocker mechanism, and a rotary angle is less than 180 DEG. The toothbrush head is fixed on the output shaft to follow the output shaft to swing forward and backward, and brush hair rubs the teeth to clean the teeth, while when the toothbrush head moves to both sides, the end face of the brush hair tilts to an angle with the outer surface of the teeth so as to avoid scratching tooth flesh.

Description

The electric toothbrush of reciprocally swinging formula
The present invention relates to a kind of follow-on electric toothbrush.
Tooth is crucial to the health of human body, and modal odontopathy is dental caries and periodontal disease, and a lot of people know the harm of dental caries, do not know that but the harm of periodontal disease is bigger, and periodontal disease is to cause the reason of many people's loss of tooth.And the reason of periodontal morbidity is because antibacterial grows at dental surface, forms film of plaque, and the infringement tooth causes.Up to the present, also do not treat the good method of periodontal disease, the method for prevention of periodontal disease is to form the good custom of often brushing teeth.Electric toothbrush is to utilize micromotor to make bristle produce rotation or vibration; the relative motion of tooth is reached the purpose of cleaning teeth by bristle; it produces high speed relative motion can effectively remove the tooth Mycoderma, reaches gingival disease, the purpose that protects the health of one's teeth.Just because of this, it more and more is subjected to people's welcome.Abroad, the use of electric toothbrush is very universal, domesticly then also is in the development phase, but along with increasing people recognizes the importance of dental health, in the near future, electric toothbrush will be widely used.So electric toothbrush has very big DEVELOPMENT PROSPECT.
Existing electric toothbrush method of work is different, square brush straight-line oscillation type is arranged, rotary cup type etc.But its shortcoming is respectively arranged, the rotary cup type complex structure, cost is higher, and square brush straight-line oscillation type bristle motion mode is damaged tooth meat etc. easily.Task of the present invention provides the electric toothbrush of a kind of follow-on reciprocally swinging formula.It is simple and practical, realize simple, and easy damaged tooth meat not.
The present invention realizes with following method.Rotatablely moving of motor output makes output shaft center on the motion of axis generation reciprocating rotating by gear mechanism and crank and rocker mechanism, the angle of revolution is less than 180 degree, and head toothbrushes is fixed on the output shaft, produces reciprocally swinging thereupon, bristle and tooth mutual friction mutually, the purpose of realization cleaning teeth.
The present invention is simple in structure, and is easy to use, bristle high speed reciprocally swinging, good cleaning teeth, the relative motion of bristle and tooth be for moving up and down, and bristle motion is during to both sides, bristle end face and the tooth angle that tilted has been avoided tooth meat, is difficult for tooth meat is damaged.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of structure longitudinal profile sketch map of the present invention.
Fig. 2 is the cutaway view Amplified image of Fig. 1 electric toothbrush along the B-B line.
Fig. 3 is the fundamental diagram of the crank and rocker mechanism that adopts of the present invention.
Head toothbrushes [1], shell [4], sleeve [5], bonnet [9], support [10], support [11], pinion [13], connecting rod [14], gear wheel [15], bent axle [16] form by plastic injection-moulded.Output shaft [2] is formed by No. 45 steel cuttings, and end mills out a facet, and the head toothbrushes [1] that prevents to be fixed on the output shaft [2] produces relative rotation with it.Its medium-height trestle [10], support [11], pinion [13], gear wheel [15], connecting rod [14] and bent axle [16] are selected wear-resistant plastic, as polyformaldehyde.Adopt between bonnet [9] and the shell [4] to be threaded, rubber seal [3] is enclosed within on the output shaft [2], is pressed between support [11] and the shell [4], is used for waterproof.Micromotor [6] is fixed on sleeve [5] lining, and by No. 5 batteries [7] power supplies, tapered spring [8] is used for compressing battery [7] and as supply access.Rotatablely moving of micromotor [6] output passed to gear wheel [15] by the pinion [13] that is fixed on the motor shaft end, and micromotor [6] output speed is reduced.Gear wheel [15] and output shaft [2] are installed on support [10] and the support [11], and can be around the slick rotation of the axis of oneself, crank [12], connecting rod [14], bent axle [16] and output shaft [2] are formed crank and rocker mechanism, Fig. 3 is the fundamental diagram of crank and rocker mechanism, bent axle [16] one ends are fixed on the gear wheel [15], the other end is coaxial with gear wheel [15], and middle have an offset distance with gear wheel [15], and gear wheel [15] and bent axle [16] are around common axis smooth rotation.The crank and rocker mechanism ABCD that forms by crank [12], connecting rod [14], bent axle [16] that rotatablely moves of gear wheel [15] makes output shaft [2] produce crankmotion, head toothbrushes [1] is fixed on the output shaft [2], produce reciprocally swinging with output shaft [2], by the friction of bristle and tooth, reach the purpose of cleaning teeth.

Claims (2)

1. tooth brushing device of forming by head toothbrushes [1], output shaft [2], shell [4], micromotor [6], battery [7], bonnet [9], pinion [13], gear wheel [15], crank [12], connecting rod [14], bent axle [16], it is characterized in that rotatablely moving of micromotor [6] output pass to gear wheel [15] by the pinion [13] that is fixed on the motor shaft end, micromotor [6] output speed is reduced; Gear wheel [15] and output shaft [2] are installed on support [10] and the support [11], and can rotate glossily around the axis of oneself, crank [12], connecting rod [14], bent axle [16] and output shaft [2] are formed crank and rocker mechanism, bent axle [16] one ends are fixed on the gear wheel [15], the other end is coaxial with gear wheel [15], middle have an offset distance with gear wheel [15], and gear wheel [15] and bent axle [16] are around common axis smooth rotation; The crank and rocker mechanism of forming by crank [12], connecting rod [14], bent axle [16] that rotatablely moves of gear wheel [15] makes output shaft [2] produce crankmotion, and head toothbrushes [1] is fixed on the output shaft [2], produces reciprocally swinging with output shaft [2].
2. by the tooth brushing device of claim 1 regulation, the anglec of rotation that it is characterized in that head toothbrushes is less than 180 degree.
