Abstract

The utility model discloses an electric tooth-cleaning device, which is used for brushing dirt on the tooth, and is composed of a brush body, a transmission device, a motor, a power supply, etc., wherein, the outer side of the brush body whose periphery is provided with brush bristles is provided with a protecting cover; 70 percent of the brush bristles are protected; one end is provided with a brush body cover; the other end and a main shaft are embedded, and are connected to form integration; the other end of the main shaft is provided with an inner gear which is engaged with a space convex gear which is fixedly connected to a motor shaft. When the motor is rotated, the main shaft is driven to rotate by the engagement of the gears. Thereby, the brush body is rotated. Simultaneously, the space convex gear touches the main shaft and a vibrating spring to drive the brush body to moved to-and-fro. Thus, rotated friction is between the brush bristles on the brush body and the tooth as well as horizontal movement, and the effect of brushing the tooth is increased.

Description

Electric tooth-cleaning device

This utility model relates to a kind of electrodynamic type device for cleaning teeth that is used to brush tooth stain that is configured to by parts such as brush body, actuating device, motor and power supplys.

Human odontopathy sickness rate is very high, and its main cause is that tooth hygiene is bad and cause, and it is very important therefore to carry out the tooth hygiene health service.Brushing teeth is one of main method of dental care, so method for brushing teeth and brushing tool are very important to keeping dental health.At present, the kind of toothbrush mainly contains two kinds of slatted and rolling type structures, its teeth brushing way also is limited and has only plug-type and swing type, and all adopt manual operations, thereby the scope and the effect of brushing teeth are restricted, brush body horizontal movement in oral cavity during especially manual brushing teeth, be unfavorable for comprehensively taking care of one's teeth, can not remove the tartar in the teeth space effectively, and manual brushing teeth, the moving number of times of brush in unit interval generally can only reach 60～80 times/minute, and strength is also inhomogeneous, can not remove tartar comprehensively; The more important thing is the tartar to the tooth inner face, craft is brushed teeth just powerless especially, can cause the gingiva damage sometimes, causes psychological inversion for the especially first toothbrushing person of toothbrushing person, makes the passive of activity change of brushing teeth.In a word, existing brushing tool and method be owing to adopt manual toothbrush, inconvenient operation and shortcoming such as to exist result of use poor, and the moving number of times of brush is few, and labor intensity is big, is unfavorable for removing the dirt in each orientation of tooth comprehensively, and health-care effect is little.

Goal of the invention of the present utility model is to overcome the shortcoming that existing toothbrushing technique exists, making a kind of is the electrodynamic type device for cleaning teeth of power with electric power, this cleaner can be done horizontal movement and vibration in the oral cavity, the dirt of comprehensive removing tooth various aspects, can not only alleviate the labor intensity of toothbrushing person, overcome the psychological inversion of toothbrushing person just, improve toothbrushing effect better.

In order to realize the foregoing invention purpose, the electrodynamic type structure that this utility model is formed by parts body plans such as brush body, actuating device, motor and power supplys.Be shaped on bristle around the brush body that adopts common process to make, brush body one end is shaped on the brush body lid, the other end is by engagement between main shaft and the gear and machine shaft interlock, and by the motion of driven by motor brush body, motor is assemblied in the end in the handgrip shell, and the other end is shaped on battery case, can lay two batteries, also can adopt alternating current steady voltage plug to substitute, a side is shaped on and off switch on the handgrip shell, with the electric connection of control motor and power supply.Brush body adopts and main shaft is nested, and structure connects as one, and reaches the shared purpose of a brush so that change brush body.

This utility model is compared with existing brushing apparatus has novel structure, uses lightly, saves time efficient height, advantage such as effective.Because existing horizontal movement has the dirt at each position of the comprehensive removing flank of tooth of vibrational energy again between brush body and the tooth, and plays the health care massage effect, be applicable to that the invalid toothbrushing person especially just of old children uses.

Fig. 1 is the principle schematic of this utility model,

Fig. 2 is the structural representation of this utility model.

The brush body 2 of this utility model adopts non-toxic plastic to make through conventional technology, and the outside is shaped on bristle 17, and left end is shaped on brush body lid 1, and the outside is shaped on guard shield 3 all around, and brush body 2 is high speed rotating and reciprocating motion under the driving of main shaft 14, to reach the purpose of the cleaning flank of tooth.Brush body 2 right-hand members and main shaft 14 adopt the structure that is nested to insert stressed joint, and be detachable, so that change brush body 2.Brush body 2 centers are moulded casting and are shaped on minor axis 18 and brush body lid 1 composition sliding bearing, play a part to support brush body 2, bear high speed rotating and reciprocating motion.Guard shield 3 protects the bristle 17 on 70% brush body 2 outsides, guarantees to make 30% bristle to contact with the flank of tooth, prevents contacting of bristle and oral soft tissue.Guard shield 3 adopts stretching and punching to make, and is connected with the position, thin end of shell 11 also detachably, is provided with the pressure point location.Brush body lid 1 is stuck in brush body 2 ends and guard shield 3 plays supporting brush body 2.On main shaft 14, be shaped on two

nylon bearings

13 and 15, be fixed on the shell 11 with supporting spindle 14 lubricating oil of can annotating between main shaft and bearing.Be shaped on sealing ring 4 at nylon bearing 15 places to prevent the mutual seepage of toothpaste and lubricating oil.Vibrating spring 5 is housed on the main shaft 14, and it and space convex gear 7 drive brush body and move back and forth, and at spring 5 left ends two pads 16 that slide relatively are housed, and one of them rotates with main shaft 14 with spring, and another plays thrust bearing.Be shaped on internal gear 6 and space convex gear 7 engagements that are connected on the motor shaft at the main shaft low order end, space convex gear 7 plays two effects, and the one, drive brush body 2 with internal gear 6 engagements and rotate; The 2nd, touch drive brush body 2 with main shaft 14 and move back and forth.Internal gear 6 and convex gear 7 adopt the injection mo(u)lding of polyamine aldehyde high-abrasive material, and modulus is 06, and internal gear 6 numbers of teeth are 37, and convex gear 7 numbers of teeth are 22.Motor is selected 151 types for use, power supply is 3 volts of direct currents, the rotating speed of motor 8 is 5000 rev/mins, fixedly be formed on left end in the handgrip shell 11, convex gear 7 is connected on its axle, be shaped on battery case 9 in shell 11 right-hand members and can load No. 5 batteries of 2 joints, also can install alternating current steady voltage plug in the place of battery case 9 to substitute battery.Be shaped on the electric connection of on and off switch 12 on handgrip shell 11 sides with control power supply and motor.The low order end of shell 11 is shaped on pressure-cliping bonnet 10 so that change battery.

When this utility model uses, the outer naked part of the bristle 17 on the brush body 2 contacts with the flank of tooth, outside identical speed of motor speed and gear tooth friction, also moves back and forth with the frequency identical with rotating speed in the horizontal direction, make tooth feel comfortable, and play the health care cleaning function.
