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
The vibration damping equipment that the present invention relates to use in appliance for personal care.
Background technique
Electromagentic resonance formula series acoustic power toothbrush, this driving adopts moving magnetic mode to belong to and utilizes alternating electromagnetic field to act on magnet, produce and brush holder support system resonance frequency, and magnet is fixed on brush holder support, and follow brush holder support motion, finally show as toothbrush head and efficiently swing with resonant frequency.These power plant are very high for vibration system coherence request in production application, and power plant volume is also larger, and portability is subject to certain restrictions.
Summary of the invention
For the deficiencies in the prior art, the invention provides the vibration damping equipment using in appliance for personal care, effectively reduced the vibration at handle place in appliance for personal care using process.
The present invention is achieved through the following technical solutions: the vibration damping equipment using in appliance for personal care, comprise mobile jib and the output shaft that is installed on described mobile jib front end, comprise a spring plain film, described spring plain film comprises node, in the relative both sides of described node, two grooves are set, described groove extends along the axial direction of spring plain film, described spring plain film is fixed by node and mobile jib, and spring plain film two ends are fixed to make it can be at mobile jib during in torsional mode, and described spring plain film can be energized around node.
In technique scheme, described two groove shape are identical.
In technique scheme, described in comprise base and gland, described mobile jib is by described base, described base is fixed on by described gland in described spring plain film two ends.
In technique scheme, on described mobile jib, be provided with mounting groove, in described mounting groove, motor be set, eccentric mass is set on motor output shaft, after electrical power rotation, drive eccentric mass to produce vibration, thereby make mobile jib produce vibration.
In technique scheme, this vibration damping equipment is for electric toothbrush.
The present invention has following beneficial effect: the present invention by arranging node on spring plain film, described spring plain film is fixed by node and mobile jib, and spring plain film two ends are fixed to make it can be at mobile jib during in torsional mode, described spring plain film can be energized around node, the present invention is simple in structure, fabricating cost is low, and has greatly reduced the impact that care implement spindle vibration produces housing.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present invention.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the structural representation of spring plain film.
Embodiment
Below the present invention is described in further detail, referring to Fig. 1 to Fig. 3, the vibration damping equipment using in appliance for personal care, comprise mobile jib 1 and the output shaft 2 that is installed on described mobile jib 1 front end, also comprise a spring plain film 3, above-mentioned spring flat board 3 roughly has the shape of rectangular flat, and described spring plain film 3 comprises node 30, at described node 30 intervals, relative both sides, two identical grooves 31 of shape are set uniformly, described groove 31 extends along the axial direction of spring plain film 3, on described mobile jib 1, be fixedly installed pad 8, described spring plain film 3 is fixing by the pad 8 on node 30 and mobile jib 1, and spring plain film 3 two ends are fixed to make it can be at mobile jib 1 during in torsional mode, described spring plain film 3 can be energized around node 30.By groove 31 distribute stress in node 30 both sides, thereby make care implement when operation, the stress of housing parts is effectively reduced.Above-mentioned node 30 is hole, by hole and coordinating of hole on pad 8 realizing being fixedly connected with of node and mobile jib 3, node is not limited to said structure certainly, and node can be also a projection, at mobile jib 3, be arranged at the mounting groove of protruding clamping, by projection, be connected with mobile jib 3 with the cooperation realization of mounting groove.
The groove width 2.50mm of described groove, flute length 17.50mm, two groove centers are apart from 5.0mm, significantly to reduce the stress of described spring plain film around described node proximity.
Described base 4 and the gland 5 of comprising, described mobile jib 1 is by described base 4, and described base 4 is fixed on by described gland 5 in described spring plain film 3 two ends, and described base 4 is fixed on the housing of care implement.
On described mobile jib 1, be provided with mounting groove 10, at the interior motor 6 that arranges of described mounting groove 10, eccentric mass 7 is set on motor output shaft, driven by motor eccentric mass produces vibration, thereby make mobile jib produce vibration, certainly make the vibrative mode of described mobile jib be not limited to this, specifically can be with reference to the structure of brush vibration in disclosed a kind of electric toothbrush in U.S. Patent number " US5378153 ", this mode discloses in this patent document, and therefore not in this to go forth.
The vibration damping equipment using in appliance for personal care of the present invention specifically can be applied to as in the care implements such as electric toothbrush, electronic clean instrument.
