Abstract
The utility model relates to an electric toothbrush, which is a scrubbing tool. The electric toothbrush is composed of two rolling brushes which are arranged on a toothbrush head rack in parallel and rotate inversely, a gear, a shaft, a motor, etc.; during operation, the toothbrush is breadthways arranged, toothbrush bristles aim at tooth surfaces, and torque output by the motor is passed down the two rolling brushes through a transmission shaft and the gear to cause the two rolling brushes to start to rotate inversely. The electric toothbrush can simultaneously realize the brushing of upper teeth from top to bottom and the brushing of lower teeth from bottom to top to play the purposes of scientific tooth brushing and gingiva protection, and even if a child can easily master. The utility model has the advantages of science, high efficiency, reliability, convenient use, etc.
Description
Electric toothbrush belongs to scrubbing tool.
The structure of existing toothbrush is to arrange many bunches of bristles at a strip planar surface, and a dull and stereotyped end is connecting a brush holder.There is following shortcoming in this toothbrush: (1) is difficult to the purpose that the realization science is brushed teeth, taken care of one's teeth.The purpose of using existing toothbrush will the realization science to brush teeth, take care of one's teeth, the action of brushing teeth must be when brushing tooth from top to bottom, scrub dental surface along gingiva from bottom to up during the brush lower tooth, otherwise will destroy gingiva, the time one, long tooth root exposed.Because tooth root is that tooth is subject to the corrosive position of inner acidic material, oral cavity most, thereby exposes gums and will directly cause multiple odontopathy.Though yet existing toothbrush also can be realized scientific and reasonable purpose of brushing teeth, extremely difficult grasp the, the especially child of gingiva most fragile.(2) brush teeth length consuming time, efficient is low.Reasonably unidirectional brush teeth action and the low characteristic of the staff operating frequency process certainty length consuming time that determined to brush teeth; Each action of brushing teeth is that bristle tips is streaked rule brush mark at dental surface, and a plurality of action brush marks also are difficult to spread all over whole dental surface, thereby brushing efficiency is inevitable lower.(3) bristle is harder, and the movement range of brushing teeth is difficult to control, often causes gingival hemorrhage.This phenomenon in the winter time or especially serious when being pressed for time after getting up morning.Because winter, the tap water temperature was lower, gingiva is very easily brushed brokenly in the further hardening of bristle; The action of brushing teeth when being pressed for time is very fast, and amplitude is difficult to control, and toothbrush head often bumps brokenly gingiva.
The objective of the invention is in order to overcome the above-mentioned shortcoming of existing toothbrush, a kind of science, reasonable, efficient, electric toothbrush reliably are provided.
The objective of the invention is to realize like this: adopt two round brush to be arranged in parallel, round brush is contained in the brush head frame 1, be positioned on the roller brush shaft of brush holder one end and be fixed with gear 4 and gear 8, gear 4 and gear 5, gear 5 and gear 9, gear 9 are meshing mutually in twos with gear 8.Gear 9 is fixedly installed in power transmission shaft 10 1 ends, and power transmission shaft 10 other ends link to each other with motor 12 main shafts by shaft joint 11, and system provides the energy by battery 13.During work, the main shaft of motor 12 is passed to gear 9 to power by shaft joint 11, power transmission shaft 10, again power is passed to gear 8 and gear 5, gear 4 by it.Because gear 8 is fixedlyed connected with round brush 7, so this moment, round brush 7 rotated up.To meshing with it gear 4, gear 4 rotations drive round brush 2 and are rotated down the gear 5 of rotation transmission of power.So just realized being positioned at top round brush 2 and be positioned at following round brush 7 and rolled in opposite directions.When brushing teeth, when being positioned at top round brush 2 and from up to down brushing tooth, be positioned at following round brush 7 and brush lower tooth from bottom to top, and need not to swing brush holder when brushing teeth, only need that brush is aimed at the flank of tooth and get final product.
Electric toothbrush is compared with existing toothbrush has following advantage:
(1) process engineering of brushing teeth is reasonable.Only need be horizontal when brushing teeth toothbrush, bristle one side is aimed at the flank of tooth and can be realized scrubbing upper and lower tooth simultaneously along the gingiva direction.The child instructs a little and can accurately grasp.
(2) brush teeth and need not to swing brush holder with hands in the process, the round brush of rotation is realized the process of brushing teeth automatically, has avoided amplitude of fluctuation to bump brokenly gingiva greatly.
(3) efficient, reliable.Electric toothbrush when work round brush high speed rotating, bristle stays brush mark moment promptly spreads all over the flank of tooth, and round brush direction of rotation decision bristle can clean slot effectively, removes food debris.Can adopt than the soft and resilient bristle of existing toothbrush, can alleviate effectively like this bristle really up to the mark bring the infringement of gingiva is not influenced toothbrushing effect.
In sum, electric toothbrush has the advantage such as scientific and reasonable, efficient, simple, reliable of brushing teeth.
Concrete structure of the present invention is provided by following examples and accompanying drawing.
Fig. 1 is the structural representation of electric toothbrush.
Fig. 2 is the working condition sketch map of electric toothbrush.
Describe the details and the working condition of the concrete structure that proposes according to the present invention in detail below in conjunction with accompanying drawing.
Parallel round brush 2 and the round brush 7 of being equipped with on the electric toothbrush head frame 1, round brush 2 and round brush 7 are installed with gear 4 and gear 8 respectively near on the roller brush shaft of brush holder one end, and gear 5 and gear 9 are installed between gear 4 and the gear 8.Meshing relation between four gears is: gear 4 and gear are 5 meshing, gear 5 and gear are 9 meshing, gear 9 is meshing with gear 8.Gear 9 is fixedly installed on the power transmission shaft 10, and power transmission shaft 10 extends in the brush holder 6, and links to each other with the main shaft of motor 12 by shaft joint 11, and power supply is provided by battery 13.
When power connection, the torque of motor 12 main shafts output passes to gear 9 by shaft joint 11, power transmission shaft 10, and gear 9 is given round brush 7 and round brush 2 transmission of torque by gear 8, gear 5 and gear 4 respectively.At this moment round brush 2 and 7 while of round brush backward rotation realize the process of brushing teeth.
