Description

Hair removal device comprising tweezers

Technical field

[01] the present invention relates to a kind of hand-holdable formula, slough the hair removal device comprising tweezers of human body fine hair.

Background technology

[02] device that comes off of described type generally includes folder, and described folder is sword sheet or the dish type that is installed on the swing roller, and described folder is can be regularly closed, open, to clamp the hair on the skin surface, and the rotation by cylinder, it is pulled out, also can remove the hair of extracting.

[03] the applicant has described a kind of described type device that comes off in patent application WO 98/30125, the described device that comes off comprises a casket body, described casket body can make the expert take and hold the described device that comes off, be equipped with in the casket body and can drive the drive motor of movable drum, after described main shaft is located at the interior hole of casket body around a main axis rotation.Cylinder comprises a few row folders, and every row folder is to form like this: the parallel successively placement of sword sheet and first group of movable sword sheet, be inserted between second group of sword sheet of identical movement, the clamp limit of sword sheet with respect to the sword sheet at the bottom of, towards the axial direction bending.Balladeur train in the middle of first group of sword sheet connects one, second group of sword sheet connects a cage, described cage with coaxial manner around balladeur train, the described device that comes off also comprises cam, described cam side direction is installed on the flange of cylinder, and described cam applies the opposite reciprocal translational motion of direction on balladeur train and cage.Described curved edges sheet constitutes the separation elastic component, and described elastic component can be inserted in the controlled motion of sword sheet, and described elastic component guarantees under minimum process stress, can better control the solid power scope of twisting.

[04] though the operational effect of the described device that comes off is pretty good, its structure and assembling are too complicated.In addition, because its structure is equipped with a plurality of members and side cam, the diameter of swing roller and wide size thereof are very big, and when the described head that comes off was placed on the malleable convex area of human body, this constituted a major defect of described device.Also can see, all double-layered quilts in every row start simultaneously, this power of electric motor that promptly means the whole group folder that need turn round simultaneously must be big, and power of electric motor also can fluctuate between the minimal power values when maximum power value when the starting folder and Dang Qi shut down in time.This requires high power motor, thereby involves great expense, and is bulky, and also can shorten its service life.

[05] proposed a kind of method among the file FR 2 662 338, described a kind of device that comes off in the described file, the described device that comes off comprises the rotary drum-type head that comes off, but the described head that comes off comprises that side direction touches the fixed disk of active blade sheet in turn.Described dish and sword sheet have a square mesopore, and can be in turn against last be the rotation drive shaft of square-section equally.Be roughly criss-cross fixed disk and put and be placed on the pad, distance equates between the dish, has four to be the holes that cross is provided with, and passes can make the control lever around main shaft.The active blade sheet is a cross also, and the expansion that comprises a square-section is mesopore fixedly, and described hole can be fixed on the sword sheet on the pad, to drive its rotation.Two control levers on the shaft diameter two ends connect first group of active blade sheet, and when two control levers were mobile in the opposite direction each other, they can drive the direction rotation of described sword sheet towards fixed disk.Two auxiliary control rods vertical with two control lever connect second group of active blade sheet, drive it and do same motion, but stagger 90 °.One roller is arranged on the end of each control lever, and described roller is engaged in the spiral slot of a stiff end bearing, and described bearing need not spring as cam, only needs described groove that the active blade sheet is moved around.Therefore, the active blade sheet is rotatable, touches the adjacent fixed dish in turn.

[06] therefore, the described device that comes off uses cam, and described cam comprises that one continues the shallow slot of profile, and control lever will have a little control lever wall, and to drive the rotation of active blade sheet, folder is closed, opened to closure in succession.Certainly, the benefit of this practice is: can reduce the energy consumption of motor, reduce noise, but can damage its hard structure, as long as its member is subjected to a little wearing and tearing, it just can't move.Therefore, in the value of the fastening force at sword sheet clamp limit place---described power is to be applied to negative several times of power on the cam control lever, and described power depends on the position of member along the uniformity of described row distribution, but not its hardness.If the size of one of described member has a little error (cam type surface, the position of sword sheet on control lever, the size of sword sheet), all can be when bringing into operation, especially the value of the effective fastening force after wearing and tearing occurring produces harmful effect.Therefore, the value of fastening force is excessive, promptly expresses possibility and can cut off hair, if especially rotary moveable sword sheet---when described sword sheet formed a wide-angle on its closing position, this point was particularly outstanding, if fastening force is too small, but can't accurately pull out hair.Especially can see that as long as a little wearing and tearing appears in cam type surface, the control arm that it can controlled bar enlarges, this can directly influence the value of all sword sheet fastening forces, with the fastening force value that the wearing and tearing of cam path reduce, and can very big reduction operating efficiency and quality.

[07] a kind of rotary drum-type device that comes off has been described among the file FR 2 663 519, the described device that comes off comprises one group of fixed disk and the active blade sheet that is disposed across on the drum spindle, described sword sheet is placed between the fixed disk, to abut in regularly respectively on the adjacent fixed dish.Described active blade sheet is independently of one another, and in axial direction free slippage is installed on two control levers, and described bar is parallel to axle, is held by two frame buccal branches, and described frame cheek can guarantee the driven unit rotation.The main shaft fixed installation of swing roller, upwards there is groove in its week, and described groove forms the cam tracks of active blade sheet.Each clamp sword sheet is engaged on itself the cam tracks on the main shaft circumference.During the cylinder rotation, the active blade sheet moves along its each cam tracks respectively, and this can make it with respect to the adjacent fixed dish, does the axial translation motion, to be resisted against on the adjacent disc, leaves in succession again.

[08] controlled the method for each corresponding active blade sheet respectively by different cams, solved the defective of the device that comes off described in the aforementioned document, in the aforementioned device that comes off, because common pivot edge sheet, the wearing and tearing of cam can hinder the operation of assembly.Equally, because the translational motion of sword sheet, flat clamp district can better distribute fastening force.But can see that fixed disk and active blade sheet more are the hard members that flushes touch.Therefore, the value of fastening force depends on the accuracy of each member (sword sheet, dish, cam tracks), and it can seriously be damaged with the wearing and tearing aggravation of cam tracks, and service time is of a specified duration, and the operating efficiency of the described device that comes off can be affected.
