The specific embodiment
Describe below in conjunction with the structure of accompanying drawing electric toothbrush of the present invention.
See also Fig. 1, Fig. 1 is the structural representation of specific embodiments of the invention electric toothbrush.Electric toothbrush comprises toothbrush body 1 and driving body 2, and wherein toothbrush body 1 is connected in driving body 2, and driving body 2 produces linear oscillator drive toothbrush body 1 and carries out linear reciprocal movement.
See also Fig. 2 and Fig. 3, Fig. 2 is the cutaway view of specific embodiments of the invention electric toothbrush, and Fig. 3 is the decomposing schematic representation of the electric toothbrush of the specific embodiment of the invention.
One end of toothbrush body 1 is a head toothbrushes, and the other end offers screw thread, is used to connect driving body 2.
Please consult Fig. 2 and Fig. 3 simultaneously.During assembling, the A chamber of the housing 20 of at first driving voltage device 21 being packed into, the B chamber of housing 20 of again magnetic core coil 22 being packed into, and the coil two ends of magnetic core coil 22 are connected in the outfan a and the b of the described control circuit module of driving voltage device 21.Then dividing plate 201 is inserted housing 20, again Attraction block 23 is encased in the C chamber by the opening of housing 20 1 sides and the opening of the dividing plate 201 between C chamber and the D chamber, then spring 25 is packed into the D chamber of housing 20 makes its two ends press on the dividing plate 201 between C chamber and the D chamber and the baffle plate 244 of driving shaft 24 respectively.Again an end of driving shaft 24 is passed the opening and the spring 25 of housing 20 1 sides and screw in the groove 232 of Attraction block 23, thereby driving shaft 24 is fixedly connected on Attraction block 23, at last the other end screw-in toothbrush body 1 of driving shaft 24 is offered a threaded end, thereby also driving shaft 24 and toothbrush body 1 are fixed up.
During use, the control of the control circuit module by driving voltage device 21 makes out the outfan a of driving voltage device 21 and b open outputting drive voltage.The coil of electric current through magnetic core coil 22 arranged after the energising, magnetic core coil 22 produces magnetic fields at this moment, and Attraction block 23 is made by the metallic iron material, so the magnetic field force that magnetic core coil 22 produces will produce captivation to Attraction block 23, makes Attraction block 23 to the direction motion near magnetic core coil 22.Simultaneously, Attraction block 23 drives the baffle plate 244 compression springs 25 of driving shaft 24, and drives toothbrush body 1 to the direction motion near magnetic core coil 22.When the control circuit module of driving voltage device 21 is closed outfan a and b outputting drive voltage, the magnetic field that magnetic core coil 22 produces will disappear, because this moment, spring 25 was in compressive state, so spring 25 will discharge elastic force, promote driving shaft 24 and drive toothbrush body 1 to direction motion away from magnetic core coil 22.Control circuit module by driving voltage device 21 sets the frequency that outfan a and b opened and closed outputting drive voltage, and promptly driving body 2 has just realized that drive toothbrush body 1 carries out linear reciprocal movement.In addition, the control circuit module by driving voltage device 21 also can be provided with the output voltage size, the magnetic field size that produces with control magnetic core coil 22, thereby the amplitude size by this magnetic field size control driving shaft 24.
Be appreciated that middle shell 20 of the present invention can also be for as other shapes such as cylinders, Attraction block 23 can also be as cobalt, nickel etc. other can be by the magnetic material of magnetic field magnetisation, spring 25 can also be for as other elastomers such as rubber plastics.
Than prior art, the elastic force that electric toothbrush of the present invention adopts magnetic core coil 22 energising backs to produce magnetic force and spring 25 drives toothbrush body 1 and carries out linear reciprocal movement, and it is simple in structure, and it is lower to be convenient to dismounting and cost.
Only be preferred case study on implementation of the present invention below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
