Abstract
The invention relates to an electric toothbrush based on non-contact magnetic coupling, which mainly comprises a toothbrush body housing, a drive subassembly and an output subassembly. The drive subassembly comprises a motor and a drive permanent-magnet connected with the motor; the output subassembly comprises an elastic component, an output permanent-magnet, an output shaft and a toothbrush head; the output permanent-magnet and the output shaft are directly fixed on the elastic component; the output permanent-magnet and the drive permanent-magnet are arranged oppositely in a non-contact manner; the drive permanent-magnet is directly arranged on the output shaft of the motor or is connected with the output shaft of the motor through a gear and a connecting bar; and the magnetic domain of the drive permanent-magnet is distributed along the radial direction or the axial direction. The electric toothbrush has the characteristics of simple structure, technology maturity, high work efficiency, etc.
Description
Technical field
The present invention relates to a kind of electric toothbrush, belong to daily living article.
Background technology
Electric toothbrush is familiar with by popular.General electric toothbrush head is made rotary oscillation, and this and dentist expert " brushing teeth along tooth " disagrees, and the rotary oscillation frequency is lower, generally is lower than 100 hertz.
In recent years, the suitable tooth electric toothbrush that is operated in hundreds of hertz of frequency of vibration begins to move towards market, and as account for the Philip Sonicare series electric toothbrush of monopoly position in market, its core technology is seen U.S. Patent No. 5,189,751.This patented technology adopts solenoid under the effect of audio pulse, forms hundreds of hertz alternating magnetic field, thereby drives the permanent magnet in this alternating magnetic field, promotes head toothbrushes and makes sliding and swaying with hundreds of hertz frequency.Because solenoid adopts open architecture, the magnetic line of force is not closed, so energy exchange efficient is lower.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of simple and reliable for structure, high efficiency, toothbrush bristle can be done the electric toothbrush of closing based on the non-contact magnetically Rhizoma Nelumbinis of sliding and swaying with the acoustic vibration frequency along tooth.
The objective of the invention is to finish by following technical solution, it mainly is made up of brush body shell, driven unit and output precision, the driving permanent magnet that described driven unit comprises a motor and is attached thereto; Output precision includes an elastic component, output permanent magnet, output shaft and head toothbrushes.
Described output permanent magnet and output shaft all are directly fixed on the elastic component, output permanent magnet and driving permanent magnet noncontact positioned opposite.
Described driving permanent magnet is directly installed on the output shaft of motor or by gear, connecting rod and is connected with motor output shaft; Described driving permanent magnet magnetic region radially distributes or makes axial distribution.
The noncontact output permanent magnet of the adjacent installation of described driving permanent magnet, this output permanent magnet is fixedlyed connected with elastic component, and at the leading section of elastic component output shaft is installed, and on this output shaft head toothbrushes is installed removably.
The present invention because the present invention makes driver part with motor, exports permanent magnet and drives permanent magnet noncontact positioned opposite compared with prior art, has simple in structure, technical maturity, characteristics such as work efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with embodiment shown in the drawings.As shown in Figure 1, electric toothbrush of the present invention mainly is made up of brush body shell 1, driven unit 2 and output precision 3 etc.; Driven unit 2 includes a motor 2a and drives permanent magnet 2b, drives permanent magnet 2b and is installed on the output shaft of motor 2a, and the output shaft of motor 2a and driving permanent magnet 2b rotate together, thereby form alternating magnetic field.Drive permanent magnet 2b and can adopt single magnetic region or a plurality of magnetic region.Change the rotating speed of motor 2a and the quantity of driving permanent magnet 2b magnetic region, thereby change the frequency of alternating magnetic field.
As to the replenishing of above-mentioned driven unit 2 structures, driving the permanent magnet magnetic region can radially distribute, and also can make axial distribution; Drive permanent magnet 2b and can be directly installed on the output shaft of motor 2a, also can be connected with the output shaft of motor 2a by mechanisms such as gear, connecting rods; And motor 2a can adopt and does gyration, also optionally waits the motor that the cycle moves as swing.
As to the replenishing of above-mentioned output precision 3 structures, elastic component can adopt the elastic component or the assembly of flat spring or other form.The output permanent magnet can be directly installed on the elastic component, also can be connected with elastic component by other mechanism; Output shaft can be directly installed on the elastic component, also can be connected with elastic component by other mechanism.
Among the present invention, can drive the magnetic region quantity of permanent magnet 2b and the magnetic region quantity of output permanent magnet 3b, head toothbrushes 3d be worked under resonant frequency, thereby improve output greatly by suitably adjusting motor 2a rotating speed.
