Embodiment Construction

[0013] Below the present invention is described in further detail, see Figure 1 to Figure 3 , the vibration damping device used in personal care equipment, including a main rod 1 and an output shaft 2 mounted on the front end of the main rod 1, and also includes a spring flat plate 3, the above-mentioned spring flat plate 3 is roughly in the shape of a rectangular flat plate, and The flat spring plate 3 includes a node 30, and two grooves 31 of the same shape are evenly spaced on opposite sides of the node 30, and the groove 31 extends along the axial direction of the flat spring plate 3. A washer 8 is fixedly arranged on the main rod 1, and the flat spring sheet 3 is fixed by the node 30 and the gasket 8 on the main rod 1, and both ends of the flat spring sheet 3 are fixed so that it can be in the torsion mode of the main rod 1 , the flat spring plate 3 can be excited around the node 30 . By distributing the stress through the slots 31 on both sides of the node 30, the stre...

Abstract

The invention discloses a damping device used in personal care equipment. The damping device comprises a main rod and an output shaft arranged at the front end of the main rod, and also comprises a flat spring plate, wherein the flat spring plate comprises pitch points; two grooves are formed in two opposite sides of the pitch points; the grooves extend along the axial direction of the flat spring plate; the flat spring plate is fixed with the main rod through the pitch points; the two ends of the flat spring plate are fixed so that the flat spring plate can be stimulated around the pitch points when the main rod is at a torsion mode. The damping device is simple in structure and low in manufacturing cost, and greatly reduces the influence of spindle vibration of a nursing device on a shell.

Description

technical field [0001] The present invention relates to vibration dampening devices for use in personal care appliances. Background technique [0002] Electromagnetic resonance series of sonic electric toothbrushes, the drive adopts the moving magnet method, which uses the alternating electromagnetic field to act on the magnet to generate a resonant frequency with the brush rod system. The resonant frequency swings efficiently. The power unit has very high requirements for the consistency of the vibration system in actual production and application, and the power unit is also relatively large in size, so its portability is limited to a certain extent. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a vibration damping device used in personal care equipment, which effectively reduces the vibration at the handle during the use of the personal care equipment. [0004] The present invention is achieved through the follow...
