Abstract
The utility model discloses a vibration reduction device used in personal nursing equipment. The vibration reduction device comprises a main rod and an output shaft installed at the front end of the main rod and is characterized in that the vibration reduction device further comprises a flat spring piece, the flat spring piece comprises a node, two grooves are formed in the two opposite sides of the node and stretch in the axial direction of the flat spring piece, the flat spring piece is fixed through the node and the main rod, and the two ends of the flat spring piece are fixed so that the flat spring piece can be excited around the node when the main rod is in a twisting mode. The vibration reduction device is simple in structure and low in manufacturing cost and greatly reduces the influence of vibration of a nursing tool main shaft on a shell.
Description
Technical field
The utility model relates to the vibration damping equipment using 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 utility model provides the vibration damping equipment using in appliance for personal care, has effectively reduced the vibration at handle place in appliance for personal care using process.
The utility model is achieved by the following technical solution: 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 utlity model has following beneficial effect: the utility model 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 utility model is simple in structure, fabricating cost is low, and has greatly reduced the impact that care implement spindle vibration produces housing.
Brief description of the drawings
Fig. 1 is decomposing schematic representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of spring plain film.
Embodiment
Below the utility model 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 in the time of 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, be arranged at the mounting groove of protruding clamping at mobile jib 3, be connected with mobile jib 3 with the cooperation realization of mounting groove by projection.
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 utility model specifically can be applied to as in the care implements such as electric toothbrush, electronic clean instrument.
