Description
The present invention relates to a kind of shave head that disposes a shave spare and a hair controller.Shave spare has a shave sword that is used for the hair of shave length on skin; From the direction that the shave head moves, also dispose a hair controller, the hair controller is positioned at the front of shave sword, and can drive along parallel with the shave sword substantially direction, so that hair is moved along parallel with the shave sword substantially direction.
The invention still further relates to a kind of electric razor that a shave head and drives the driving mechanism that this shave head uses that has, the shave head disposes a shave spare, shave spare has a shave sword that is used for the hair of shave length on skin, the shave head also disposes a hair controller, from the direction that moves along the shave head; The hair controller is positioned at the front of shave sword, and this controller also can make hair move along the direction that is parallel to the shave sword substantially along parallel with the shave sword substantially direction by this drive mechanism.
EP-A-0855256 discloses that class shave head and electric razor of mentioning in opening paragraph.Shave spare in this known shave head and the electric razor is placed in the place, a fixed position in the shave head.Its hair controller has a comb along shave sword arranged parallel, has on the comb substantially along the tooth that extends perpendicular to the direction of shave sword.When running, by driving mechanism the relative shave spare of hair controller is produced along the direction that is parallel to the shave sword and move back and forth.The user along moving direction on skin during mobile shave head, hair is at first grabbed between the tooth of hair controller.Each between cog has comparatively speaking little space, thereby can hair be produced along the reciprocating motion that is parallel to shave sword direction substantially by the hair controller, thereby during shave, hair just moves back and forth along this shave sword.The result makes to have significantly along the required shave power of the moving direction of shave hair and reduces, the shave performance of shave head and shave comfort level are improved significantly.This hair controller also can provide protection, does not make skin incised wound and irriate.The shave head is during moving on the skin, and the skin that the hair controller also will be in shave sword front flattens along being parallel to this moving direction, reduces widely thereby make at relatively large skin wrinkle shave sword front, that skin is hurt.When the hair controller moves back and forth along the direction that is parallel to the shave sword, the hair controller also will be in the skin flattening of shave sword front along the direction that is parallel to this shave sword, thereby make between hair controller tooth, may cause that little incised wound and skin irritant comparatively speaking little skin wrinkle are also reduced widely.
The shortcoming of this known shave head and electric razor is: if the hair controller of shave spare driving is suitable relatively, above-mentioned shave function and prevent skin incised wound and stimulate, just from along perpendicular to shave sword direction, could realize when shave spare has very accurate position relatively, and from perpendicular to the direction of shave sword with from perpendicular to this moving direction, only allowing has relative little gap between this shave spare and hair controller.Just because of this, the shave head must have makes the hair controller relative to the point-device guiding of having moved of this shave spare, is to the precision of the used structure of shave head or to the dimensional tolerance that is allowed in the manufacturing of shave head high requirement to be arranged all therefore.So just cause the design of shave head and make all relatively complicated.
The purpose of this invention is to provide a kind of shave head and electric razor of in opening paragraph, mentioning, this shave head and electric razor can prevent to very high degree incised wound and the stimulation to skin, but also can reduce the shortcoming of above-mentioned known shave head and electric razor as much as possible.
In order to realize this purpose, the feature of the shave head among the present invention is: the hair controller is placed in a position fixing with respect to shave spare, and shave spare can drive along the direction parallel with the shave sword together with the hair controller.
In order to realize this goal of the invention, a kind of electric razor among the present invention is characterised in that wherein used shave head is the shave head among the sort of the present invention.
Because the hair controller is placed in the fixing position of relative shave spare, so the shave head need not to have and is used to accurate guide rail that the hair controller is moved relative to shave spare.In the manufacturing of this shave head, as an example, the hair controller is anchored on the fixing position of relative shave spare, thereby makes and to obtain the desired relative position of shaving part of accurate hair controller in simple relatively and reliable mode.Because have been found that, the position of resulting shave spare/relative shave head of hair controller assemblies need not as the position of the relative shave spare of hair controller accurate, and the configuration of shave head is a kind of moves relative to first of this shave with the hair controller for shave spare relative to easy guide rail so can give.Because hair controller and shave spare can drive along the direction that is parallel to the shave sword substantially together, when the shave head is mobile on skin, skin wrinkle can be eliminated by this hair controller substantially, thereby can make this hair controller can prevent incised wound and skin irritatin to heavens as in this known shave head and the electric razor.
One specific embodiment of shave head of the present invention is characterised in that this hair controller and shave spare constitute a separate piece.When making this separate piece, the hair controller can relatively easily be disposed at or be made on this shave spare with desired precision.The structure and the assembling of shave head have so just been simplified again widely.
One specific embodiment of the electric razor among the present invention is characterised in that, this electric razor disposes in order to produce the mechanism that shave spare moves back and forth, this moves back and forth has an edge and the parallel component of shave head moving direction at least, the shave power required along this moving direction shave hair reduces significantly, has therefore improved the shave performance and the shave level of comfort of this shave head significantly.
After having understood the embodiment that introduces below, these aspects of the present invention and others will seem clearer.
Each accompanying drawing is:
Fig. 1 has showed that one disposes the electric razor embodiment of shave head of the present invention;
The some of the shave head shown in Fig. 2 exploded view 1;
Fig. 3 a shows the part of 11 integral body of another shave head of the present invention embodiment, and
Fig. 3 b is along III b-III b side cross sectional view among Fig. 3 a.
Fig. 1 shows the embodiment of electric razor 1 of the present invention, this razor has a shell 3, utilize on the shell 3 retention mechanism 7 with removably fastening a shave head 5 of the present invention, for for simplicity, 7 of retention mechanisms roughly are showed among the figure, and it can be each traditional type of understanding per capita.Hold a motor 9, in the shell 3 and giving the battery 11 of motor 9 power supplies and the electrically-controlled component 13 of a control motor 9 usefulness.Motor 9 can be disposed at switch 15 on the shell 3 with one and start or turn-off.
As illustrated in fig. 1 and 2, shave head 5 configuration one shave spare 17, shave spare in the embodiment shown 17 is flat, disposes a linearity shave sword 19 of the hair that grows from skin in order to shave on it.Shave sword 19 extends with directions X perpendicular to the moving direction (being shave direction Y) of shave head 5 abreast along one.Shave head 5 also has a hair controller 21, disposes a comb 23 in the present embodiment on the hair controller 21 shown in.Described comb 23 places on the frame 25 of hair controller 21, and tooth 27 is arranged.Tooth 27 is substantially along extending perpendicular to the direction of shave sword, and from along shave head 5 moving direction Y, tooth 27 is placed in the dead ahead of shave sword 19.Should be noted that tooth 27 is to be disposed at along on the total length of shave sword 19 substantially, but for simplicity, on Fig. 2, only show several teeth 27.As illustrated in fig. 1 and 2, shave spare 17 is fixed in the place, fixed position on the frame 25 of hair control device 21, and the comb 23 of hair controller 21 is placed in respect on the fixing position of shave spare 17.In the present embodiment, tabular shave spare 17 is anchored on the upper surface 29 of frame 25 with retention mechanism 31.Just showed retention mechanism 31 in Fig. 1 and 2 roughly, they can be each traditional types of knowing per capita.Sees along the direction that is parallel to directions X, but frame 25 guided with the relative shave headstock 33 of reciprocating manner, and dispose for this reason and guide the guide member 35,37 of ditch 39,41 mating reactions.This guiding ditch 39,41 extends along the direction that is parallel to directions X, and is set on the shave headstock 33.Frame 25 can be driven along the direction parallel with directions X by the driving mechanism 43 of electric razor 1.Driving mechanism 43 is placed in the housing 3, and has above-mentioned motor 9.Driving mechanism 43 also comprises an output shaft 45 and a pin 47 of motor 7.Pin 47 is placed on this driving mechanism prejudicially, and acts synergistically with the ditch 49 that is produced on the frame 25.The direction that is parallel to directions X from the edge, ditch 49 has and the suitable width of pin 47 diameters, thereby makes that can change the rotation of the output shaft 45 of motor 9 into hair controller 21 is parallel to moving back and forth together of the direction of directions X, the relative shave headstock 33 with the edge of fastening shave spare thereon 17.
As user during along the electric razor 1 of moving direction Y moving belt shave head 5 on pending skin, hair controller 21 just plays a part to prevent to hurt and chafe.Owing to see along moving direction Y, hair controller 21 is in the front of shave sword 19, flatten along the direction parallel so hair controller 21 directly will be in the skin 51 of shave sword 19 fronts, skin is reduced widely by shave sword 19 big relatively skin wrinkles incised wound, in shave sword 19 fronts thereby make with the Y moving direction.Because hair controller 21 moves back and forth along the direction that is parallel to shave sword 19, hair controller 21 is also flattening along being parallel to the skin 51 that will be in shave sword 19 fronts on the direction of shave sword 19, may cause the relatively little skin wrinkle of 27 in less incised wound or skin irritant, as to be in hair controller 21 tooth also to be reduced widely thereby also just make.When the user on skin 51 during mobile shave head 5, longly as shown in Figure 1 just grabbed between the tooth 27 of hair controller 21, and arrived shave sword 19 places that thereupon want this hair of shave at the hair on the skin 51 53.For example, if see along the direction that is parallel to X, the width of tooth 27 and interval are in 0.1～0.4 millimeter scope, and hair controller 21 reciprocating frequences are about 100 hertz or higher, and amplitude can obtain the protection effect of enough hair controllers 21 roughly between 0.05 to 0.25mm.
Only have been found that tooth 27 at hair controller 21 just can make hair controller 21 that enough protection effects are arranged when being in the predetermined accurate position of shave sword 19 of relative shave spare 17.Specifically, as shown in Figure 1 at a slit 55 of 27 in shave sword 19 and tooth must be less than a relative little predetermined value along the width on the direction vertical with shave sword 19.Because shave spare 17 and hair controller 21 interfix with retention mechanism 31 in shave head 5 of the present invention each other, the exact position of required tooth 27 relative shave swords 19 can relatively reliably and easily be realized by simple relatively retention mechanism 31 during shave head 5 is made.Owing to have been found that, can allow shave spare 17 quite low precision to be arranged with the position of the headstock 33 of hair controller 21 relative shave heads 5 on it, so the guide member 35 of hair controller 21, if 37 and the guiding ditch 39,41 of the shave headstock 33 have extremely low precision just enough.Therefore, for shave head 5, the protection effect of hair controller is to obtain by the structure of improving shave head 5 and manufacturing process, and its structure and manufacturing process and the shave head with similar protection effect for example want much simple with the comparing of shave head at EP-A-0855256.In the shave head of EP-A-0-855256, shave spare is placed in the place, a fixed position of shave head, and must use the accurate guide rail of the relative shave spare of hair treatment device.
In shave head 5 of the present invention, grabbed between the tooth 27 of hair controller 21 hair by hair controller 21 along and the parallel substantially direction of shave sword 19 move back and forth.Because hair controller and shave spare 17 are fastened onto on the position fixed relative to one another, so this hair does not move back and forth along shave sword 19, so shave head 5 does not limit required shave power in the mode of the disclosed the sort of shave head of EP-A-0855256.In order still to realize, disposed a usefulness for electric razor 1 so that shave spare 17 produces the mechanism 57 that moves back and forth along being parallel to moving direction Y to restriction along the shave power parallel with shave head 5 moving direction Y.Have now found that along under the sort of moving influence parallel with moving direction Y, required shave power has significantly and reduces at shave spare 17.In the embodiment shown, mechanism 57 constitutes in simple especially mode, and there is a unbalance mass, 59 that tightens up with eccentric manner with the output shaft 45 of motor 9 in mechanism 57.And mechanism 57 can replace with different modes and using.In other embodiment, two in its motor driving hair controller and described mechanism, one speed changer can be used between motor and this mechanism and/or be used between motor and the hair controller, and this speed changer can make shave spare obtain conforming with the desired frequency ratio along the direction that is parallel to X with between the direction that is parallel to Y moves.
In above-mentioned shave head 5 of the present invention, shave spare 17 and hair controller 21 are two discrete items that tightened up mutually during shave head 5 is made.But the present invention also can have such embodiment; Shave spare and hair controller are made into a single piece together, and the structure of shave head and assembling are further simplified.A sort of single piece 61 that is used for another embodiment of the present invention is shown in Fig. 3 a and 3b.This embodiment is being identical with above-mentioned shave head 5 basically aspect all the other.Single piece 61 is tabular metal frame 63, be manufactured with ditch 65 with each traditional machined operation of understanding per capita in the frame 63, but also the tooth 67 by each the traditional process for machining of understanding per capita configuration rounding, the tooth 67 of this rounding is positioned on the tabular metal frame 63.In addition, the upper surface 69 of frame 63 is processed to shave sword 71, and this shave sword 71 is fabricated between a pair of adjacent teeth 67.Single piece 61 also has unshowned in the drawings guide, and they are used for relative shave head along the direction guiding single piece 61 that is parallel to shave sword 71.
