Floating structure possesses the floating spring 21 that boosts razor head 2 and reinforcing.Set the elastic force of the back-moving spring 26 of the first cutoff tool unit 11 littler than the elastic force of the floating spring 21 of floating structure.
Make the top of the first cutoff tool unit 11 that is positioned at position of readiness be positioned at top than the second cutoff tool unit 12 by the top.Thus, when shaving, can make the first cutoff tool unit 11 tiltedly moving before other cutoff tool unit 12,13.
Effect of the present invention is as follows.
In the present invention, utilize tiltedly moving framework 25 to support outsides 23 and inner edge 24 and constitute cutoff tool unit 11,, thereby can utilize central gear 60 rotations to drive the inner edge 24 of tiltedly moving displacement around the axle supporting tiltedly moving framework 25 in axle center consistent with the axle center of central gear 60.In addition, can utilize back-moving spring 26 to make cutoff tool unit 11 automatically reset to position of readiness.So, if the cutoff tool unit 11 that can tiltedly move independently is set on razor head 2, then compare with making the whole tiltedly moving existing electric shaver of razor head, the 11 tiltedly moving displacements of cutoff tool unit can be made with littler skin reaction force, and the variation of skin surface can be followed sleekly.Therefore, can shave easily.
As if the front and back that first, second cutoff tool unit 11,12 are configured in the first half of central gear 60, the oblique kinetic moment around the axle center consistent with the axle center of central gear 60 of utilizing deadweight to produce is always acted on the first cutoff tool unit 11 that can support tiltedly movingly.If the first cutoff tool unit 11 that is positioned at position of readiness utilizes the elastic force of back-moving spring 26 to overcome above-mentioned oblique kinetic moment and the holding position, but the skin reaction force acts, then overcomes the elastic force of back-moving spring 26 and tiltedly moving displacement.The oblique kinetic moment of the first cutoff tool unit 11 of this moment is followed from the increase of the oblique angle of moving of position of readiness to be increased.This is that the arm of force of the first cutoff tool unit 11 is big more because tiltedly moving angle increases more.Therefore, can utilize the increase of oblique kinetic moment to reduce the increase of back-moving spring 26 elastic force when tiltedly moving in the first cutoff tool unit 11, reduce the skin reaction force in the tiltedly moving process in the first cutoff tool unit 11, thereby can make the 11 tiltedly moving displacements of cutoff tool unit with littler skin reaction force.In addition, the degree that the skin reaction force when shaving reduces correspondingly reduces the stimulation to skin surface, thereby can shave easily.
Owing to first, second cutoff tool unit 11,12 is configured in the front and back of central gear 60, and make the first cutoff tool unit 11 tiltedly moving around the axle center consistent with the axle center of central gear 60, when therefore tiltedly moving in the first cutoff tool unit 11, the interval of two cutoff tool unit 11,12 can be enlarged, thereby skin surface can be stretched.In detail, to tiltedly moving away from the direction of the second cutoff tool unit 12, at this moment, the skin surface of 11,12 of the two cutoff tool unit of stretching erects thereby can make to be poured on the frizzle on the skin surface and to become mildewed when shaving in the first cutoff tool unit 11.Therefore, any that can utilize two cutoff tool unit 11,12 shaved effectively and removed to erecting the beard of state.
If make central gear 60 turning moment direction with utilize back-moving spring 26 consistent to the direction of tiltedly moving framework 25 reinforcings, then can utilize above-mentioned turning moment to assist the homing action of the first cutoff tool unit 11 by back-moving spring 26.Thus, the reset force that can produce with the turning moment by central gear 60 correspondingly reduces the spring pressure of back-moving spring 26, therefore, can make the first cutoff tool unit 11 tiltedly moving more easily with littler power.
If make the diameter difference of inner edge 24,40 of first, second cutoff tool unit 11,12 of the front and back of being located at razor head 2, then can increase the contact area of the cutoff tool unit 12 that possesses the big inner edge of diameter 40 and skin surface, thereby can correspondingly shave effectively at short notice.In addition, with regard to the cutoff tool unit 11 that possesses the little inner edge of diameter 24, existence diminishes with the contact area of skin surface, the skin reaction force correspondingly becomes big tendency, thereby can essence shave undercoat.Therefore, utilize first, second two cutoff tools unit 11,12 slightly to shave collaboratively and essence is shaved, thereby can in the shorter time, shave effectively.
If the peripheral speed of inner edge 24 that diameter is little is set identically or littler than the peripheral speed of inner edge 40 with the peripheral speed of the big inner edge 40 of diameter, then can reduce the little sword of the little inner edge of diameter 24 and skin surface butt number of times, reach amount of friction and relax burden skin surface.In addition, in the big inner edge 40 of diameter, since big with the contact area of skin surface, therefore can shave simultaneously and remove more substantial beard, but need bigger driving torque.In order to ensure this driving torque, the driving rotating speed that the driving speed setting of the inner edge 40 that diameter is big gets the little inner edge of diameter group 24 is little.In addition, can increase with the driving torque of inner edge 40 and correspondingly effectively shave, thereby can relax burden skin surface.
As mentioned above, in possessing the first cutoff tool unit 11 of the little inner edge of diameter 24, compare the skin reaction force with another cutoff tool unit 12 and act on consumingly, skin falls into the inside of outside 23 easily.Therefore, the stimulation increase to skin has the tendency that is easy to generate tingling sensation.But, if tiltedly moving mode supports around the axle center consistent with the axle center of central gear 60 can make the first cutoff tool unit 11, then can be corresponding with the minor variations of skin reaction force, make the first cutoff tool unit 11 tiltedly moving sensitively, therefore can prevent from exceedingly to push skin surface.
Between first, second cutoff tool unit 11,12, be provided with the 3rd cutoff tool unit 13, if drive its inner edge 47 by central gear 60 and 63 rotations of inner edge gear, then utilize the gear drive of a side of being located at razor head 2 to carry out the driving of each cutoff tool unit 11～13 simultaneously.Therefore, can open the following side space of each cutoff tool unit 11～13 fully, thereby remove soft flocks more easily.For example, constitute the occasion that comprises round portable inner edge 47 in the 3rd cutoff tool unit 13, the following side space of at least the three cutoff tool unit 13 is occupied by the inner edge drives structure, can't prevent soft flocks attached to its surface, spends time in cleaning.In addition as mentioned above, the skin surface because the first tiltedly moving cutoff tool unit 11 can stretch, erect thereby make to be poured on the frizzle on the skin surface and to become mildewed, therefore can utilize the 3rd cutoff tool unit of being located between the two cutoff tool unit 11,12 13 to shave effectively and remove the beard that erects.
If the main part 1 by the double as handle can support razor head 2 with fluctuating, then can make the 11 tiltedly moving displacements of the first cutoff tool unit certainly, and razor head 2 is fluctuated with respect to main part 1.Therefore, the user can shave under the state that the first cutoff tool unit 11 is tiltedly moved, or make the first cutoff tool unit 11 tiltedly move, also shave, thereby can when shaving, diversely select pushing force to skin surface while razor head 2 is fluctuated.
If set the elastic force of the back-moving spring 26 of the first cutoff tool unit 11 littler than the elastic force of the floating spring 21 of floating structure, then, can limit fluctuating of razor head 2 up to because of the tiltedly moving spring pressure of back-moving spring 26 that causes in the first cutoff tool unit 11 surpasses setting.Therefore when shaving, can either prevent that razor head 2 from unnecessarily fluctuating, can shave reliably making under the tiltedly moving state in the first cutoff tool unit 11 again.In addition, the second cutoff tool unit 12 is being pressed against under the situation of skin surface tightly, fluctuating, preventing from exceedingly to stimulate skin surface, thereby can relax burden skin surface by making razor head 2.
If being positioned at than the top of the second cutoff tool unit 12, the top of the first cutoff tool unit 11 that is positioned at position of readiness leans on the top, then when shaving, at first make the first cutoff tool unit 11 before other cutoff tool unit 12,13, push skin surface, under the state that skin surface is extended, shave.Therefore, can utilize a plurality of cutoff tools unit 11,12,13 to shave simultaneously and remove the beard of the skin surface of utilizing 11 extensions of the first cutoff tool unit, thereby can shave operation at short notice effectively.
