Description

Can regulate the defeathering utensil of hair extraction distance

What the present invention relates to is a kind of utensil that is used for removing the hair that grows from skin, this utensil is provided with a clamping device, be used for a hair being clamped and this hair being pulled away skin at least in part with sending out, and one the cutting device, be used at the proximate skin place the hair cut that is partly pulled away skin.

From United States Patent (USP) 3,088, can know a kind of as one section mentioned utensil of top beginning in 205.This known utensil comprises the cutting member of a pectination, and this cutting member is provided with row's cutting element and can vibrates.The cutting element of cutting member is pressed on the sheet metal, then is provided with hair on the above-mentioned sheet metal and is absorbed in opening.Cutting member and then comprise a clamping element, a flexible metal band or a rubber strip for example, this clamping element is arranged in the both sides of first cutting element, and its position is fixed with respect to cutting member.The hair that passes hair trap openings when operation at first is clamped between one of them of sheet metal and clamping element, and when the relative sheet metal of clamping element moved, hair was partly pulled away skin.Subsequently, when the sword of the cutting element of a contiguous its corresponding clamping element and an its corresponding hair trap openings was cooperated mutually, hair promptly was cut off, and a part that is clamped to the hair between sheet metal and the clamping element this moment is promptly cut.Because the hair that is so prescinded is no longer clamped, so the hair that is prescinded turns back within the skin its terminal falling under skin surface.Like this, obtained the smooth capillary effect fruit of shaving by using clamping element, and skin still can keep smooth in the quite a long time after shaving hair.

A shortcoming of known appliance is: before hair is cut off its part being pulled away this process of skin has a pain.Therefore, compared with using common everybody known shaver, the shaver that promptly only cuts is removed hair pain more with this known utensil.The nonoptional leeway of the user of this known appliance.Usually the user can obtain the effect that shaves more smooth when using the shaver that dissection is only arranged with this known utensil, but remove hair by this known appliance to a certain degree pain is always arranged.

A target of the present invention provides a kind of above-mentioned shortcoming of also avoiding above-mentioned known appliance as the mentioned utensil of front beginning section as much as possible.

For this purpose, utensil according to the present invention is characterised in that: this utensil is provided with an adjusting device, is used to regulate the distance that clamping device was extracted hair before cutter sweep cuts off hair.The fact that napkin bag according to the present invention contains above-mentioned adjusting device makes the user of this utensil can regulate clamping device and given the freedom that the user selects what hair was transferred to apart from this before cutter sweep cuts off hair.The user can be provided with, for example, one relatively short extraction distance, above-mentioned distance provides a more rough effect but make defeathering not produce pain basically of shaving really, perhaps the user also can be provided with a relatively long extraction distance, this distance provides very smooth effect and this effect of shaving to remain unchanged in considerable time really, but this defeathering process pain relatively.Alternatively, the user also can, for example, a general extraction distance is set, it can obtain good smooth effect and this effect and can reasonably remain unchanged in a period of time, and to follow the pain degree of this distance be acceptable.

A specific embodiments according to a kind of utensil of the present invention is characterised in that: the device that is used to regulate extraction distance can transfer to a primary importance at least, extraction distance was zero or was roughly zero and transfer to a second place this moment, and this moment, clamping device was extracted hair fully from skin.In this special embodiment, utensil has a wide applications.When first was provided with, hair or was not hardly pulled away skin so utensil and is had painless dissection uniquely before device to be cut is cut off.When second was provided with, utensil had the epilation function, and this moment, hair was extracted fully from skin.In addition, said apparatus can, for example, between first and second settings is continuously adjustable, so that make the user can be the most smooth one, the smooth retention time the longest (be provided with relatively more sorely to realize by second) and one least smooth, the arbitrary needed effect of selection between the smooth retention time the shortest (be provided with not have realize by first) painfully.The user also can, for example, earlier be provided with to send out to prescind and then a prior hair that has prescinded is set and pull out with second becoming mildewed with first of this utensil.

Another embodiment according to a kind of utensil of the present invention is characterised in that: clamping device comprises at least one clamping element, this element hair trap openings of utensil relatively moves, the device that is used to regulate extraction distance then comprises an adjusting device, is used to regulate clamping device used dynamics when grip hair.In this embodiment, it is the result that the relative hair trap openings of clamping element is moved that clamped hair is pulled away skin.If give the device setting one relative stronger clamping force that is used to regulate the clamping dynamics, between clamping element movably and clamped hair less relatively slip will take place then, therefore clamped hair will be driven a relatively long distance by clamping element movably, thereby realize a relatively long extraction distance.If give the device setting one relative more weak clamping force that is used to regulate the clamping dynamics, between clamping element movably and clamped hair relatively large slip will take place then, therefore clamped hair will be driven a relatively short distance by clamping element movably, thereby realize a relatively short extraction distance.Therefore can regulate extraction distance with a simple mode.

Another embodiment again according to a kind of utensil of the present invention is characterised in that: clamping device comprises the cooperation clamping element of at least one pair of, this element can move with respect to hair trap openings, the device that is used to regulate extraction distance then comprises an adjusting device, is used to regulate the position of cutter sweep with respect to clamping device.Hair is clamped between the co-operating clamping element and when above-mentioned co-operating clamping element moves with respect to hair trap openings in the place of contiguous hair trap openings and is pulled away skin in this embodiment.The cut position of clamped hair is determined with respect to the position of clamping device by selected cutter sweep.The distance that clamping device was extracted hair before cutter sweep cuts off hair is determined by the position distance between the two that is clamped between the cut position of hair and the clamped device of hair.Because the cut position of hair can be regulated with respect to the position of clamping device by regulating cutter sweep, so can regulate extraction distance by the above-mentioned position of regulating cutter sweep simply.

A specific embodiments according to a kind of utensil of the present invention is characterised in that: clamping device is arranged on a bearing part, this bearing part can be around a pivot axis parallel with hair trap openings, this bearing part is provided with an elasticity parallel with pivot center and clamps a band and a static clamping cover of cooperating with above-mentioned clamping band, this clamping is covered hair and is absorbed in opening and roughly is concentric arrangement with respect to pivot center, cutter sweep then is positioned on the edge of clamping cover of hair trap openings, and the device that is used to regulate the clamping dynamics comprises that then one can make and clamps the device that cover relatively rotates axis shift.In this embodiment, hair is set at the elasticity clamping band that rotates on the bearing part and clamps and be clamped to subsequently between clamping band and the elasticity clamping cover, fastening being tightened to of above-mentioned clamping cover, for example, on the shell of utensil.When clamping band when clamping cover and rotate, clamp the band band and hair and move together and hair is extracted from parts of skin ground, this moment and can some slips of generation between hair and static clamping cover between clamping band that moves and hair.Because clamping cover is movably with respect to the position of pivot center,, be adjustable between the clamping dynamics that clamps band and clamp between the cover so clamp band when clamping cover and move in elasticity.Less relatively clamping force causes clamping between band and the clamped hair relatively large slip takes place, thereby obtain a relatively short extraction distance, relatively large clamping force then causes clamping between band and the clamped hair less relatively slip takes place, thereby obtains a relatively long extraction distance.Because being arranged at, cutter sweep clamps in the edge that covers hair trap openings, cut off in local device to be cut so partly pull away the hair of skin, so just make by the part of each the root hair that pulls away skin and cut off long as much as possible near skin.

Another embodiment according to a kind of utensil of the present invention is characterised in that: cutter sweep comprises two dentation cutting blades that pitch is identical, they parallel by adjacent arrangement and with pivot center, the cutting blade that deviates from pivot center is static, another cutting blade then can be driven with mode of vibration along the direction parallel with pivot center, and the rotation of this oscillating movement and bearing part and clamping band is synchronous.Because the rotation towards the vibration of the cutting blade of pivot center and bearing part and clamping band is synchronous, cutter sweep will clamp band with respect to a set position of the clamping cover on quiet clamped hair cut, promptly can be at the extraction distance of a set clamping device clamped hair cut.Cutting blade has equal pitch and means all positions at the dentation cutting edge of cutting blade, cutting blade cuts simultaneously, the cutting function that so just makes cutting blade is in all cut direction, in same mode, with the rotational synchronization of bearing part and clamping band, so just can obtain the extraction distance of homogeneous.

Another embodiment again according to a kind of utensil of the present invention is characterised in that: the quiet cutting blade of going up of cutter sweep is side-prominent the arriving outside the vibration cutting blade of cutter sweep towards hair trap openings.Hair is partly pulled away skin cause forming so-called skin cone round above-mentioned hair, this cone can disappear when hair is cut off.Because the static cutting blade of cutter sweep is side-prominent the arriving outside the swing cutting blade of cutter sweep towards hair trap openings, so above-mentioned skin cone just can be pushed back by static cutting blade, so just avoid the skin cone to enter between the tooth of cutting blade to cause skin to be damaged.

Be characterised in that according to one of a kind of utensil of the present invention special embodiment: hair trap openings on one day from the side of cutter sweep in abutting connection with a skin-tightening element, this skin-tightening element extends through on the virtual plane of static section one and extends along the direction that is parallel to pivot center.The use of skin-tightening element prevents that skin from contacting with the bearing part of the rotation of clamping device, prevents that also skin from being clamped.In addition, can deeper penetrate among the hair trap openings thereby the skin-tightening element can make hair lift, the bearing part band of the rotation of the clamped device of hair the possibility that moves has together so just increased largely.

Another embodiment according to a kind of utensil of the present invention is characterised in that: co-operating clamping element be set at one can bearing part around pivot axis on, hair trap openings is set on the flexible cover sheet, above-mentioned flexible cover sheet also can be around pivot axis in small angle range around bearing part and the setting of cooperation clamping element thereof, cutter sweep then comprises a cutting element, this cutting element, see along the direction that bearing part rotates, be set on the cover sheet and close on an end of hair trap openings.The hair that passes hair trap openings is clamped between the co-operating clamping element and is also partly pulled away skin subsequently under the influence that clamping element rotates.The rotation of clamping element moves on to the hair that is arranged in hair trap openings the above-mentioned end of hair trap openings simultaneously, and the cutting element that is used to cut clamped hair is located in this end.Because hair trap openings and cutting element all are arranged on the flexible cover sheet of the rotation axis rotation that can rotate, cutting element is with respect to the position of clamping device, and then the extraction distance of clamping device, just can regulate by the rotation of cover sheet simply.

Another embodiment again according to a kind of utensil of the present invention is characterised in that: the cutting element that is arranged on the cover sheet is a cutting edge that defines hair trap openings.In this embodiment, relative to covering under the effect that sheet rotates, clamped hair is cut off by above-mentioned cutting edge at co-operating clamping element.Cutting edge in connection with hair trap openings has formed a simple and practical especially cutting element.

Be characterised in that according to one of a kind of utensil of the present invention special embodiment: cutter sweep also comprises a cutter spare in addition, the cutting edge that is used for being absorbed in hair opening is cooperated jointly, above-mentioned cutter spare is set on the bearing part and closelys follow after collaboration elements (rotation direction along bearing part is seen), and extends along the direction parallel with pivot center.In this embodiment, the hair that is clamped by co-operating clamping element has so just improved the cutting function of cutter sweep owing to the mutual cooperation between the cutter spare of hair trap openings and rotation is cut off on sizable degree.

Another embodiment according to a kind of utensil of the present invention is characterised in that: hair trap openings is one to be positioned at the slit of cover on the sheet, and it extends along the direction that bearing part rotates, and sees to have the profile that diminishes gradually along the rotation direction of bearing part.The profile that diminishes gradually that slit extends along the bearing part rotation direction provides the very high possibility that clamps hair, also avoids the damage of cutter sweep to skin simultaneously as much as possible.

As Fig. 1 a, first embodiment according to a kind of utensil 1 of the present invention shown in the 1b and 2 is provided with a shell 3 that has defeathering head 5, and above-mentioned head 5 is provided with a hair trap openings 7.Be provided with a defeathering spare 9 in defeathering head 5, skin can be exposed to above-mentioned defeathering spare 9 by hair trap openings 7, so that remove the hair that grows from skin.

Shown in Fig. 1 b and 2, defeathering spare 9 comprises a clamping device 1 and a cutting device 13.Clamping device 11 comprises a cylindric metal bearing part 15, and bearing part 15 can be rotated with respect to shell 3 and defeathering head 5 around pivot center 17 by axle journal supporting, and above-mentioned pivot center 17 extends along the direction parallel with hair trap openings 7.Bearing part 15 has the clamping band 19 of some, for example can have six this kind bands, and above-mentioned band 19 is arranged at the equal intervals place of bearing part 15 and extends along the direction that parallels with pivot center 17.Clamping band 19 is by an elastomeric material, and for example rubber or elastic synthetic resin are made.Bearing part 15 and clamp band 19 and can rotate around pivot center 17 by motor 21, as Fig. 1 G institute was graphic, above-mentioned rotation realized by mechanical driving device, mechanical driving device is that common everybody is known, does not illustrate in the drawings.

As shown in Figure 2, clamping device 11 and then comprise a clamping cover 23 of being made by metal or synthetic resin is used for and clamps band 19 and cooperate mutually.As following institute will further explain, clamping cover 23 resting positions of living in was adjustable with respect to shell 3 and defeathering head 5.Clamp cover 23 and be provided with a clamping surface 25, surface 25 is consistent with arranging roughly with the concentric imaginary circle cylinder of pivot center 17.Clamping cover 23 and clamping surface 25 are defined by the edge 27 of a rounding, and hair trap openings 7 is pressed close at edge 27.When operation, when motor 21 direction that arrow indicated in as Fig. 2 drives bearing part 15 and clamps band 19, clamp band 19 and promptly slip over clamping surface 25 as shown in Figure 2 successively.

Further show brightly as Fig. 1 b and 2, cutter sweep 13 comprises a so-called hairclipper 29, and hairclipper 29 is provided with two cutting blades 31 and 33, above-mentioned cutting blade 31 and 33 adjacent are arranged to clamp in the cover 23 and with the pivot center 17 of bearing part 15 parallel.Shown in Fig. 1 b, a side 35 towards hair trap openings 7 on the cutting blade 31 of bearing part 15 is provided with cutting teeth 37, then is provided with cutting teeth 41 away from one on the cutting blade 33 of bearing part 15 side 39 towards hair trap openings 7.Cutting teeth 37 and 41 has identical pitch and is projected into outside the edge 27 that clamps cover 23.The cutting blade 33 that is positioned at skin side is static, the relative position that is it and shell 3 and defeathering head 5 is fixed, another cutting blade 31 then can be by a motor 21 along the direction vibration that parallels with pivot center 17, above-mentioned vibration realizes by another mechanical driving device, this mechanical driving device is common and for everybody is known, also not shown in the drawings.Be projected into outside the side 35 of vibration cutting blade 31 as Fig. 1 b and 2 sides 39 that further show bright, static cutting blade 33.Hair trap openings 7 deviates from a side that clamps cover 23 at it and is defined by a skin-tightening element 43, and said elements 43 extends along the direction that is parallel to pivot center 17.

Explain that as above-mentioned clamping cover 23 is adjustable with respect to shell 3 and with respect to the resting position that is fixed on the bearing part 15 in the shell 3 with the bearing of journals.As shown in Figure 2, for this purpose, clamp cover 23 and be connected on the shell 3 by a hinge pin 45, above-mentioned hinge pin 45 is extended along the direction that is parallel to pivot center 17.Clamp cover 23 and be maintained on the position with respect to shell 3 by a depression bar 47, depression bar 47 can be regulated nut 49 by one and be moved along longitudinally, and nut can be rotated by the user of utensil 1.Clamp displacement that the clamping surface 25 of cover 23 can be by depression bar 47 and move a bit of distance with respect to pivot center 17, like this at clamping surface 25 and clamp the clamping force that produces between the band 19 and just can be regulated along radially direction roughly.In addition, further mechanical driving device between the vibration cutting blade 31 of mechanical driving device between the bearing part 15 of motor 21 and clamping device 11 and motor 21 and cutter sweep 13 is configured to make the vibration of cutting blade 31 and to clamp the rotational synchronization of band 19 with bearing part 15, promptly, as long as the clamping band 19 that accompanies is in the both allocations with respect to the clamping surface 25 that clamps cover 23, the cutting blade 31 of cutter sweep 13 and 33 will be the hair cut that is positioned between the cutting teeth 37,41.This is synchronized with the movement and can be able to reality by the gear ratio that above-mentioned mechanical driving device is set in everybody common known mode.

The operation of utensil 1 is as described below.When operation, when utensil 1 being placed on the skin 51 that has hair to be removed 53, hair 53 promptly can pass hair trap openings 7 as shown in Figure 2.Entered in the hair trap openings 7 hair 53 at first by clamp band 19 one of them with motion together and be clamped at corresponding clamping band 19 subsequently and clamp between the clamping surface 25 of cover 23.Fig. 2 shows that bright one is clamped to a hair 53a who clamps between band 19a and the clamping surface 25.After corresponding hair 53a has been clamped between clamping band 19a and the clamping surface 25, cover 23 moves continuously and exist friction between hair 53a and clamping band 19a because clamping band 19a is with respect to clamping, so hair is being with clamped band 19a together and is being moved, hair 53a is just partly pulled away skin like this.Hair 53a pasted the edge 27 that clamps cover 23 and was bent this moment, and hair 53a just is cut off in the place of proximate skin by a cutter sweep 13 that is arranged at 27 places, edge like this.Partly pulled away after skin and hair 53a cut off by proximate skin, the not cut part of hair 53a just turns back among the skin, this moment hair 53a not an end of cut part just fall under the surface of skin 51.Fig. 2 shows with the form of example and understands that one is so cut off and turns back to hair 55b among the skin 51 with a terminal 57b.Like this, just can obtain one by the mutual cooperation between clamping device 11 and the cutter sweep 13 and smooth shave the capillary effect fruit.Because the hair that is so cut off will be grown to the height of skin surface again and need the regular hour, so so the smooth effect that obtains can remain unchanged in the quite a long time.

As discussed above, hair clamped device 11 parts before device to be cut 13 is cut off pull away skin clamping device 11 and cut off the so-called extraction distance before the hairs hair extracted especially by clamping band 19 and clamping clamping force between the clamping surface 25 of cover 23 at cutter sweep 13, and clamp band 19 with respect to the position decision of clamping surface 25 at above-mentioned position cutter sweep 13 clamped hair cut, this position is along with being synchronized with the movement and deciding between the top mentioned mechanical driving device.Because the user of utensil 1 can regulate the clamping dynamics that clamps between band 19 and the clamping surface 25 by regulating nut 49, so he also can regulate above-mentioned extraction distance.If the user is provided with clamping force lessly relatively, relatively large slip will take place clamping band 19 and be clamped between the hair that clamps band 19 and clamp 23 on cover then, clamp band 19 like this and just only move a limited distance, and realize a relatively short extraction distance with hair.If the user is provided with clamping force relatively largely, less relatively slip will take place clamping band 19 and be clamped between the hair that clamps band 19 and clamp 23 on cover then, clamp band 19 like this and will move a relatively long distance, and realize a relatively long extraction distance with hair.Just as known, hair from parts of skin pull up the generation pain sensation, this pain sensation increases along with the increase of extraction distance.In view of the above, the user can freely select by using adjustable clamping cover 23.Thereby one extraordinary smooth effect that the user can be provided with a relatively large clamping force and the certain reality of extraction distance, and this effect can remain unchanged in the quite a long time, but clamping device 11 will cause relatively large pain in this is provided with.As an alternative, the user also can be provided with a less relatively clamping force and an extraction distance, and this moment, clamping device caused pain hardly, but thus obtained smooth effect only can keep relatively short a period of time.

Cutting so reaches in the time of all cutting teeth 37,41: the cutting teeth 37 of the cutting blade 31,33 of cutter sweep 13,41 have identical pitch, promptly when clamping band 19 and be positioned at it with respect to both allocations of clamping surface 25, all cutting teeths 37,41 all cut. Whole side 35,39 at cutting blade 31,33 just can obtain a uniform extraction distance like this.Because the side 39 of static cutting blade 33 is projected into outside the side 35 of vibration cutting blade 31, so can stop so-called skin cone to enter between the cutting teeth 37,41 of cutter sweep 13 and cause skin damage bad.This skin cone appears at around clamping device 11 hair that clamped and that partly pulled away skin gives birth to, and disappears when corresponding hair is cut off.Use skin-tightening element 43 can prevent that skin from contacting with the bearing part 15 of rotation, can prevent that also skin is clamped between bearing part 15 and the clamping cover 13.And the hair that lies low on skin can be holded up by skin-tightening element 43, and these hairs just can enter hair trap openings 7 and are being with mobile together by bearing part 15 like this.Preferably skin-tightening element 43 runs through on the virtual plane of static cutting blade 33 one and extends.Obtaining cutter sweep 13 with respect to the mode of the optimum position of skin is, cutting blade in the position of pressing close to very much skin surface clamped hair cut.

What deserves to be mentioned is: the user of utensil 1 can alternatively be arranged on one first extreme position clamping cover 23, and the clamping force that clamps this moment between band 19 and the clamping surface 25 is zero or is substantially zero.When clamping cover 23 was arranged at this position, the distance that clamping device was extracted hair before cutter sweep 13 cuts off hairs was little as can to ignore, and utensil 1 just serves as a traditional shaver like this.The user also can be alternatively be arranged on one second extreme position clamping cover 23, clamps that clamping force between band 19 and the clamping surface 25 is big must to be enough to make clamped hair to be extracted fully from skin before device to be cut 13 has an opportunity to cut off this moment.Like this, when clamping cover 23 was positioned at second extreme position, utensil 1 served as a traditional epilation utensil.Be worth one connect be: utensil 1 also can obtain a traditional epilation function in the following way, that is: the further mechanical driving device of being for motor 21 and vibration cutting edge 31 be provided with a kind of can be by the coupling connection of user's dialysis.In this alternate embodiment, thereby the user just can obtain a traditional epilation function by cutter sweep 13 is closed in the dialysis of the coupling of above-mentioned further mechanical driving device connection.Utensil 1 just has very wide applications like this.For example, the user can be arranged on its first extreme position to the clamping cover 23 of utensil 1 so that long hair is cut short, and then is arranged on its second extreme position so that the hair of having cut short is in advance pulled out clamping cover 23.Moreover, as mentioned above, the user also can be arranged on a centre position between first and second extreme positions clamping cover 23, and this position provides deep layer function user's this moment that shaves can make a balance between the pain degree that shaves effect and will stand.

As Fig. 3,4,5a, among second embodiment 101 according to a kind of utensil of the present invention shown in 5b and the 5c, shell 103 is provided with a defeathering head 105, and head 105 is provided with hair trap openings 107.One defeathering spare 109 is arranged in defeathering head 105, and skin can be exposed to defeathering spare 109 so that remove the hair that grows from it by hair trap openings 107.

As shown in Figures 3 and 4, defeathering spare 109 comprises that a clamping device 111 has a cutting device 113.Clamping device 111 comprises the co-operating metal clamping disk 115 of some, and clamping disk 115 and a driving shaft 117 be the coupling connection mutually, and above-mentioned driving shaft 117 can be driven by a motor 121 and can be around a pivot center 119 rotations by a mechanical driving device 124.Each clamping disk(-sc) 115 all can carry out around pivot deflection with the perpendicular pivotal line relative drive shaft 117 of pivot center 119 around one.Have and the rotor motion rotatable with having of institute from European patent EP-B-0532106 of the structure of clamping device 111 of clamping disk 115 of rotatable and rotor motion with operation the epilation head structure and operate roughly corresponding.In EP-B-0532106 the structure and the operation of clamping device 111 correspondingly thought and be incorporated among the content of the present patent application.Clamping disk 115 is cooperation mutually in couples, and adjacent a pair of clamping disk is by arriving clip position around pivot deflection, is clamped between their clamping surface 125 thereby will cross the hair that catch opening 107 and be exposed to clamping device 111.At above-mentioned clip position, the clamping surface 125 of above-mentioned clamping disk 115 compresses and produces a clamping force mutually.Dish 115 by mutual clamping is with respect to the continuous rotation of hair trap openings 107, and clamped hair is partly pulled away skin subsequently.

Further show brightly as Fig. 3 and 4, cutter sweep 113 comprises flexible metal cover sheet 127, and cover sheet 127 is provided with around the driving shaft 117 that carries co-operating clamping disk 115.As at Fig. 5 a, can be clear that among 5b and the 5c, above-mentioned hair trap openings 107 is set on the cover sheet 27, above-mentioned cover sheet 127 has the hair trap openings 107 that its form is a slit 129 thereon, above-mentioned slit extends along the rotation direction of clamping disk 115, and each slit correspondence each co-operating clamping disk 115 adjacent to the position.See that along the rotation direction of clamping disk 115 slit 129 has wedge-type shape.One defines the cutting edge 133 of an end 131 of slit 129 near the above-mentioned end 131 of each slit 129, as what see along the rotation direction of clamping disk 115.What deserves to be mentioned is that for simplicity, Fig. 5 a, the number of slit 129 shown in 5b and the 5c and clamping disk 115 are than the decreased number shown in Fig. 3.

Further show as Fig. 3 bright, cover sheet 127 one with direction that pivot center 119 parallels on be enclosed in one at first groove 135 among the shell 103 and between second groove 137 among the shell 103.As shown in Figure 4, groove 135 and 137 encloses two terminal extensions of valiant driving shaft 117, the cover sheet just has the possibility that is directed and moves among groove 135 and 137 like this, and can be rotated a limited angle around driving shaft 117 and turning cylinder 119 by the user of utensil 101.To explain further that below cover sheet 127 rotates the effect that is produced.

As Fig. 4,5a, shown in 5b and the 5c, cutter sweep 113 types and comprise that the axis 119 that the cutter 139 of some, these cutters 139 are parallel to rotation extends, and is designed in order to cooperate mutually with the cutting edge 133 of slit 129.Cutter 139 is not shown in Figure 3 for simplicity.Cutter 139 almost extends and is enclosed in respectively in separately the groove of arranging in regular turn 141 along the total length of driving shaft 117, and groove 141 is arranged among the clamping disk of arranging in regular turn 115 and is positioned at one and is parallel on the imaginary plane line of pivot center 119.Rotation direction along clamping disk 115 sees that each cutter 139 is all located and followed closely after the co-operating clamping surface 125 of clamping disk 115.As described in the EP-B-0532106, each clamping disk 115 all has 125 and 125 ', two surfaces 125 and 125 ' of two clamping surfaces to be positioned on two radiuses 143 and 143 ' of clamping disk 115, and the mutual angle between above-mentioned two radiuses is 120 °.EP-B-0532106 and then how to have described thereby identical clamping disk 115 is fastened to the clamping disk 115 that makes on the driving shaft 117 in succession around driving shaft 117 each hexagonal angles that rotate mutually.Therefore cutter sweep 113 just is provided with three cutters 139, and these cutters 139 lie low on three radiuses 145 of clamping disk 115 and form one 120 ° angle mutually.

Explain the operation of utensil 101 below with reference to Fig. 5 a, 5b and 5c.In Fig. 5 a, cover sheet 127 is positioned at one first extreme position, and this moment, utensil 101 served as a traditional shaver, as following the explanation.In Fig. 5 b, cover sheet 127 is positioned at one second extreme position, and this moment, utensil 101 had traditional epilation function.In Fig. 5 C, cover sheet 127 is in a centre position between first and second extreme positions, and this moment, utensil 101 had the function that a deep layer shaves.In each position shown in Fig. 5 a, 5b and the 5c, 115 pairs of the adjacent clamping disks of some have just pivoted by clamping disk 115 and have entered into clip position, and this moment, the preliminary election hair that passes hair trap openings 107 was clamped between the clamping surface 125 of co-operating clamping disk 115.This position of clamping disk 115 is a reference position, indicates by line of reference A-A in Fig. 5 a, 5b and 5c.

When cover sheet 127 is in centre position shown in Fig. 5 c, clamped hair subsequently by co-operating clamping disk 115 with respect to the continuous rotation of hair trap openings 107 from parts of skin extract.When the clamping surface 125 that clips hair therebetween arrived soon after the cutting edge 133 of hair trap openings 107, the hair of being extracted from parts of skin was cut off because of mutual cooperation the between the cutter 139 of contiguous clamping surface 125 and the cutting edge 133.Like this, when the centre position shown in the cover sheet 127 of utensil 101 is positioned at, utensil 101 promptly has the deep layer function that shaves, and at this moment, hair clamped device 111 is earlier extracted certain distance from skin, and then device to be cut is cut off in the position of proximate skin.So just obtain the smooth effect that shaves, and this effect can remain unchanged for a long time, as explaining with reference to utensil 1.

The distance that clamping device 111 was extracted hair before cutter sweep 113 cuts off hair can be regulated around the rotation of clamping disk 115 by cover sheet 127.When cover sheet 127 rotates, it will change the position of the cutting edge 133 of cutter sweep 113 with respect to clamping device 111 and line of reference A-A.If cover sheet 127 begins from the centre position shown in Fig. 5 C to rotate along the rotation direction of clamping disk(-sc) 115, then the distance between cutting edge 133 and line of reference A-A will increase, and extraction distance also can increase like this.Consequently can increase pain during defeathering, but because cut hair deeper falls into to be got back under the skin surface, so so the smooth effect that obtains can keep the long time.If cover sheet 127 begins from the centre position shown in Fig. 5 C to rotate along the negative side with the direction of rotation of clamping disk 115, then the distance between cutting edge 133 and line of reference A-A will reduce, and extraction distance also can reduce like this.Pain more not during defeathering consequently is so but the more shallow smooth effect that so obtains only can remain unchanged in the short period of time under the skin surface because cut hair returns to.

When cover sheet 127 was on first extreme position shown in Fig. 5 a, cutting edge approximately was positioned on the line of reference A-A.When cover sheet 127 when being in this position, hair is clamped between the clamping surface 125 of co-operating clamping disk 115 and then because the mutual cooperation between cutting edge 133 and the cutter 139 almost is cut off at once.Correspondingly, when cover sheet 127 was in this position, clamped hair did not have before being cut off or is not almost extracted from skin, so when cover sheet 127 was in this position, utensil 101 had traditional function that shaves.What deserves to be mentioned is: when first extreme position of cover sheet 127 make cutting edge 133 be positioned at before the line of reference A-A before the time (rotation direction along clamping disk 115 is seen), also can obtain this traditional function that shaves.At this moment, hair is not clamped between the clamping disk 115, but is cut off immediately because of the mutual cooperation between cutting edge 133 and the cutter 139.What deserves to be mentioned is in addition: if cover sheet 127 is positioned at first extreme position, and cutting edge 133 is positioned on the line of reference A-A, or following (rotation direction along clamping disk 115 is seen) after the line of reference A-A closely, the cutter sweep 113 of utensil 101 is not provided with cutter 138 also can have cutting function.In this alternate embodiment of utensil 101, be clamped at hair between the clamping surface 125 of co-operating clamping disk 115 and be held dish 115 and be with and rotate together and cut off by cutting edge 133.

When cover sheet 127 was in second extreme position shown in Fig. 5 b, the distance between incision tip 133 and the line of reference A-A was so big so that the hair that is clamped between the clamping surface 125 of co-operating clamping disk 115 was fully extracted from skin before arriving cutting edge 133.When cover sheet 127 was in this position, utensil 101 had traditional epilation function.

The little width of profile that diminishes gradually of the slit of hair trap openings 107 (seeing along the direction that driving shaft 117 rotates) and the contiguous cutting edge 133 that causes thus prevents that as much as possible hair trap openings 107 that skin passes contiguous cutting edge 133 also and then be cut sword 133 or cutting edge 133 and cutter 139 and damage.Slit provides the higher possibility of catching hair at the relatively large width that the side away from cutting edge 133 is had.

The clamping device 11 of above-mentioned utensil 1 comprises that one has a bearing part 19 that rotates and a clamping cover 23 that clamps band 19, clamp cover 23 and be and be used for to clamp band co-operating, the clamping device 111 of above-mentioned utensil 101 comprises that then one has the driving shaft 117 of the rotation of clamping disk 115.What deserves to be mentioned is: the alternative form that a kind of clamping device also can be set according to a kind of utensil of the present invention, at least one clamping element promptly is set, this clamping element can move with respect to the hair trap openings of device, the alternative form of another kind of clamping device also can be set, at least one pair of co-operating clamping element promptly is set, and these clamping elements can be with respect to the hair trap openings precession campaign of device.Therefore, for example, in utensil 1, can replace clamping band 19 with co-operating clamp, above-mentioned clamp can move with respect to bearing part 15 along the direction that is parallel to pivot center 17.In utensil 101, for example, also can replace having the driving shaft 117 that can change clamping disk 115 with the alternative type of a rotating supporter around pivot, above-mentioned supporter is provided with a plurality of clamps, and the direction that these clamps can parallel along the axis with the supporter rotation is moved with respect to supporter.

The cutter sweep 13 of utensil 1 described above comprises a hairclipper 29, and the cutter sweep 113 of utensil discussed above 101 has the cutting edge 133 of some, these cutting edges 133 be used for the rotary cutter 139 of some co-operating.What deserves to be mentioned is: the cutter sweep that can be provided with alternative type according to utensil of the present invention.Therefore, for example, in utensil 1, available one single vibration is shaved and is cut tool and replace hairclipper 29.Moreover in utensil 1, static cutting blade 33 can be provided with to such an extent that directly be pressed on the skin in use.In utensil 101, for example, can one dissimilar cutting element be set to substitute cutting edge 133 on the sheet 127 at cover, for example can use one to be parallel to the shaver that driving shaft 117 extends.

In the utensil of being discussed in the above 1, the distance that clamping device 11 was extracted hair before cutter sweep 13 cuts off hairs used clamping force when regulating clamping device 13 grip hair can be regulated, and in utensil 101, extraction distance is regulated with respect to the position of clamping device 111 by the cutting edge 113 of regulating cutter sweep 113.It should be noted that at last: the device that is used to regulate extraction distance that an alternative form can be set according to utensil of the present invention.Therefore, for example, in utensil 1, be used to regulate the device 45 of the clamping dynamics of clamping device 11,47,49 can be substituted by the vibration device that is synchronized with the movement between the two of the cutter sweep 31 of the rotation of the bearing part 15 that is used to regulate clamping device 11 and cutter sweep 13.Clamp band 19 with respect to clamping surface 25 residing positions in the time of can being adjusted in cutter sweep B hair cut that is clamped between clamping band 19 and the clamping surface 25 by this replacement device, above-mentioned position is a criterion of extraction distance.
