The specific embodiment

Fig. 1 is a functional diagram, shows the embodiment of the electric razor that designs according to the present invention.This figure relates to a kind of situation in the unhairing process.It has not only highly schematically represented each function element of razor, and provides and be used to carry out may connect up according to each electronic component of localization method of the present invention.In the embodiment about razor, razor has a rotatable cutter head 1, and it is installed to be can be around the axle rotation vertical with this plan.Cutter head 1 comprise first blade, 2, the second blades 3 and be installed in blade 2 and blade 3 between central cutter 4.In illustrated situation, second blade 3 contacts with user 6 skin surface 5 physics.Cutter head 1 rotates with respect to the shell in user's 6 hands 8 by positioner 7.Two blades 2 with 3 and central cutter 4 be connected with circuit 9 conductions respectively: first blade 2 is connected with the base stage of the first transistor 10; Second blade 3 is connected with the base stage of transistor seconds 11; Central cutter 4 is connected with the base stage of the 3rd transistor 12.

Transistor

10,11 and 12 the equal ground connection of emitter stage.The colelctor electrode side, the first transistor 10 is connected with the input and first collector resistance 14 represented with F1 of control logic circuit 13; Transistor seconds 11 is connected with the input and second collector resistance 15 represented with F2 of control logic circuit 13; And the 3rd transistor 12 is connected with the input and the 3rd collector resistance 16 represented with MS of control logic 13.Control logic circuit 13 has an output of representing with Z, and it can be connected to positioner 7 by driving stage 17.

Collector resistance

14,15 and 16 is interconnection each other further, and equally with shell 8 in user's 6 hands has an electromotive force Vdd.Under the effect of human body resistance 18, shell 8 is electrically connected by user 6 with second blade 3.For reaching this purpose, shell 8 is at least partially conductive.According to the position of cutter head 1, can also have with the respective electrical of the central cutter 4 and first blade 2 to be connected.Human body resistance 18 is represented user 6 skin surface 5 and the total effective resistance between the hand.

In the embodiment shown in fig. 1, the operations according to the instant invention principle is that cutter head 1 is rotation so all the time, makes two

blades

2 and 3 be adjacent to skin surface 5.For this reason, need on the one hand to obtain about two

blades

2 and 3 whether with the skin surface 5 actual information that are adjacent to, need on the other hand to design a kind of mechanism, be used to make cutter head 1 to have at least a position that is not adjacent to skin surface 5 to rotate to the position that two

blades

2 and 3 all are adjacent to skin 5 from blade 2 and 3.Whether make the circuit 9 of constructing among Fig. 1 produce electric current by detecting two

blades

2 and 3, can obtain about which is adjacent to the information of skin surface 5 in blade 2 and 3.If

blade

2 or 3 is adjacent to skin surface 5, flow through human body resistance 18 and form unique loop of electric current.If, such as, in situation shown in Figure 1, second blade 3 is adjacent to skin surface 5 and therefore is formed into the electric current of the base stage of transistor seconds 11 through human body resistance 18, transistor seconds 11 switches by the input F2 of logic control circuit 13 and with its ground connection so, otherwise input F2 is electromotive force Vdd.If first blade 2 is adjacent to skin surface 5, said circumstances is equally applicable to first blade 2.Because switching

transistor

10,11 and 12 only needs very little electric current, the electric current of the human body resistance 18 of flowing through is perfectly safe for user 6 and can not be discovered.

Control logic circuit 13 is analyzed the signal of its input reception and is controlled driving stage 17 in view of the above; Then, driving stage 17 is controlled positioner 7 in the same manner; Cutter head 1 just can rotate by predetermined way like this.Control logic circuit 13 is analyzed according to the truth table shown in the table 1; This table is input F1, and each group signal combination of F2 and MS is given a control command at the output Z place of control logic circuit 13.The situation of control logic circuit 13 input end groundings in truth table with " 0 " expression, and the input electromotive force to be the situation of Vdd represent with " 1 ".That is, " 0 " expression contact with skin and " 1 " represent and skin contactless.Whether the signal indication central cutter 4 at control logic circuit 13 input MS places is adjacent to skin 5, and its detection mode is with identical to the detection mode of input F1 and F2 place signal.The signal of considering control logic circuit 13 input MS places is not to be absolute necessary, but because of it centre position is also taken into account, so can control cutter head 1 better.

Table 1: truth table

Shown in truth table, if two

blades

2 and 3 all are adjacent to skin surface 5 or all are not adjacent to skin surface 5, cutter head 1 place and original position.Whether central cutter 4 is adjacent to 5 pairs of above-mentioned two kinds of situations of skin surface is not had materially affect.In a kind of modification,, can also make cutter head 1 rotate to the reference position lentamente if neither one is adjacent to skin surface 5 in two blades 2 and 3.When only having first blade 2 not to be adjacent to skin surface 5, the positioner 7 of geometry shown in Figure 1 turns right lentamente, and promptly clockwise direction rotates; Thereby cutter head 1 is to anticlockwise.Further, if central cutter 4 is not adjacent to skin surface 5, suppose that then cutter head 1 more serious position error and positioner 7 occur and turns right rapidly.Conversely, when only having second blade 3 not to be adjacent to skin surface 5, positioner 7 turns left lentamente; In addition, if central cutter 4 is not adjacent to skin surface 5 yet, positioner 7 can turn left rapidly.

Circuit 9 is used for detecting information about the position of two

blades

2 and 3 as checkout gear on the one hand, is used for according to the information control positioner 7 that records as control device on the other hand.Its detection and control function are constantly repeated, thereby whether duplicate detection has electric current to analyze by human body resistance 18 and according to truth table.Like this, the position of cutter head 1 constantly is changed, and contacts with 3 skins that show expectation until two blades 2.Two blades 2 contact with 3 skin thereby realize by setting up a kind of control loop.Be further to strengthen dynamically and the serious site error of correcting cutter head 1 as far as possible apace, can also be in the position fixing process of cutter head 1 pick up speed.

When blade 2 when 3 all contact with skin, resistance difference that forms between they and the shell 8 or the impedance contrast that forms with the latter respectively can be used for locating more accurately cutter head 1.When two blades do not produce above-mentioned difference simultaneously with the effect that contacts of skin.That is, when being crushed on the skin than another more tightly, a blade produces above-mentioned difference.So the cutter head rotation, thereby also be pressed on the skin together with identical dynamics until the resistance or the impedance phase of two blades.Be particularly conducive to like this and produce the desirable effect that shaves.

Supplementary functions as the above-mentioned spinfunction that is used to optimize the skin contact can also realize idle function, rotates to position of readiness according to this function cutter head 1 after the razor outage.Under this position of readiness,

blade

2 and 3 is towards shell 8, thereby avoids the infringement of external action.Similarly, also can following design cutter head 1: by rotary cutter 1 blade system is replaced with another set of cutting system, as become mildewed and remove cutter or difficult region-specific defeathering system.Whether other supplementary functions can also be, be touched or whether the element of cutter head 1 contacts with skin and control each indicator elment or connect razor automatically according to shell 8.Especially, when cutter head 1 contacts with skin without any element, also can reduce the driving power of razor.If razor has assembled linear motor, this function is especially suitable at last.

The function of removing cutter of becoming mildewed can be used as a kind of additional function and realizes.In this case, the user can press button and makes cutter head rotate to a certain position; This position can be used the known cutter that is installed in a certain appropriate location on the cutter head especially easily.This becoming mildewed removed cutter and comprised, such as, a fixing comb; This comb plays a role and has with the blade that driven by mode of vibration and chips.

According to razor of the present invention, whole drive system, promptly the oscillatory driver of independent component and the positioner 7 that makes cutter head 1 rotation in the cutter head 1 can be integrated in the cutter head 1.Cutter head 1 just can have the essential anglec of rotation arbitrarily like this.Similarly, also each driver can be installed in razor shell 8 respectively with interior and beyond cutter head 1.Fig. 2 has provided such embodiment.
