Specific embodiment

The explanation of following embodiment be with reference to attached drawing, can be to the specific embodiment implemented to the example present invention. The direction and position term that the present invention is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outside", " top Portion ", " bottom ", " side " etc. are only direction or position with reference to attached drawing.Therefore, the direction and position term used be to Illustrate and understand the present invention, rather than limiting the scope of the invention.

The invention will be further described with reference to the accompanying drawing.It please refers to shown in Fig. 1, this is a kind of sense electronics of the present invention The structural schematic diagram of wet absorption articles embodiment one, in figure sense electronics wet absorption articles 10 include disposable paper urine pants, nappy, Diaper, diaper core etc., structure includes:

Absorbed layer 15, this is the key that one of absorbent item composition, is mainly used for absorbing the urine (urine) of body discharges And excrement (stool).The absorbed layer of disposable absorbent article generally includes the suction such as cotton pulp, wood pulp and macromolecule absorption material (SAP) The property received substance.

Below absorbed layer 15, including a flexible water film layer 11, to prevent the urethral leakage in absorbed layer.It would generally Waterproofing membrane is made using soft nontoxic sealed polyethylene plastic (PE), some waterproofing membranes can also breathe freely (referred to as ventilative Film), this both waterproof and vapor-permeable film is commonly used on baby paper diaper.

In the upper surface of absorbed layer 15, including a permeable braid layer 18, which generallys use soft permeable hydrophilic Non-woven fabrics is taken on.Due to moisture pass through permeable braid layer 18 after, be the absorbed layer 15 in high molecular material absorb and After locking, braid layer 18 would generally restore again dry and comfortable, so 18 can be described as dry and comfortable layer again.

The area of flexible water film layer 11 and permeable braid layer 18 would generally be big than absorbed layer 15, so its four side It will there are certain surpluses.In process of production, all can between waterproof film layer 11, absorbed layer 15 and permeable braid layer 18 It is bonded by glue spraying/gluing mode, enables absorbed layer 15 that can be fixed between waterproof film layer 11 and permeable braid layer 18.Due to Waterproof film layer 11 and 18 4 side of permeable braid layer are all larger than absorbed layer 15, the peripheral position except beyond absorbed layer 15 On, waterproof film layer 11 and permeable braid layer 18 can be bonded directly together, and form the neighboring area that an annular closes envelope. Since this neighboring area does not have absorbed layer presence, the moisture in absorbed layer can not reach these positions, i.e., the described region meeting one It is straight to keep dry condition, therefore the region can be known as to annular free from dampness safety zone.

Absorbed layer is divided into two regions by the embodiment of the present invention, is referred to as the first absorption region 151 and the second uptake zone Domain 152, the line of demarcation of the first, second absorption region are 150.It is following for convenience to further describe, figure again in by 152 points be Tri- regions 152a, 152b, 152c, correspond respectively to A, B, C in figure.First absorption region 151 is that the front end of paper diaper (makes Used time corresponds to the preabdomen position of user), it is closer to the urination position of paper diaper user, the region can then be defined To urinate wet (urine) detection zone.And the second absorption region 152 is the rear end of paper diaper (corresponding to the low back of user when use Portion position), it is closer to the defecation position of paper diaper user, which can be then defined as to stool detection zone again.

In order to realize the stool and urine detection function of sense electronics wet absorption articles, an inspection is also needed to configure in practical applications Survey device 20.Detection device would be normally located at the front end of paper diaper on the position of the first absorption region, because of this position Set corresponds to the preabdomen of user, and influence to user is minimum, therefore the embodiment of the present invention is by the output of induction electrode End 12 is located within the free from dampness safety zone of paper diaper front end (hereinafter referred to as the first safety zone), to facilitate and detect dress Set 20 electrical connections.In embodiments of the present invention, it is preferred to use carbon electrically conductive ink prints to generate induction electrode, because printing out The conductive line of induction flexibility come is good, can fold, and the use of paper diaper is not influenced, in embodiments of the present invention by this electrode Referred to as flexible electrode.Embodiment one kind, the flexible electrode be printed on waterproofing membrane 11 towards absorbed layer 15 this Face, i.e., between waterproofing membrane 11 and absorbed layer 15.The flexible electrode of the embodiment of the present invention one includes at least one the first Flexible electrode 121 and at least one the second flexible electrodes 122, two strip electrodes since first safety zone, respectively along The free from dampness safety zone that annular closes envelope extends to the left and right sides, until reaching the free from dampness safety zone of 10 rear end of paper diaper Within (the hereinafter referred to as described region is the second safety zone), this arrangement be can effectively avoid in the first absorption region of paper diaper 151 Influence/interference of the urine to flexible detecting electrode 121,122, therefore the electrode 121,122 of the embodiment of the present invention can be used to examine Survey the moisture conditions in paper diaper specific region (such as second absorption region).

It also include at least one third flexible electrode 125 and at least one the 4th flexible electrode 126 in Fig. 1, it is described 125,126 this one side of permeable braid layer 18 towards absorbed layer 15 is printed on above (18 lower surfaces), due to pacifying in free from dampness In entire area, waterproofing membrane it is upward with permeable braid layer it is downward while mutually bond, so first is flexible It can be achieved to be electrically connected between electrode 121 and third flexible electrode 125 and the second flexible electrode 122 and the 4th flexible electrode 126 It connects, and generates electrode connection points 127,128.

Through the above configuration, electrode 121,122 is able to realize the conversion of different level by electrode 125,126, i.e., conductive Circuit is transferred in the permeable braid layer 18 absorbed layer 15 above from the waterproofing membrane 11 of the lower section of absorbed layer 15, and from close the In the position transfer of one absorption region 151 to the second absorption region 152, realize to table on absorbed layer in the second absorption region 152 The moist detection in face can be by 125,126 short circuit of electrode, to enable detection when 152 upper surface of the second absorption region occurs moist The resistance in circuit becomes smaller.In embodiments of the present invention, the circuit that should be formed by 121,122,125,126 is referred to as first resistor inspection Survey time road.It can be seen that, electrode 125,126 is the main part of measure loop in from the above, and electrode 121,122 is detection The resistance variations information of electrode 125,126 can be transferred to output end 12, and can further transmitted by the connection transition portion in circuit Correlation method for data processing is carried out to detection device 20, then by 20, and the analysis and judgement for whether having stool and urine to occur made.

The first resistor measure loop of embodiment one is primarily to detecting the defecation situation of paper diaper user and being arranged 's.Since it avoids the moisture effect of the first absorption region (urinating wet detection zone), and is extended into from paper diaper rear end Two absorption regions (stool detection zone, is analyzed for convenience, and the second absorption region is divided into tri- regions A, B, C again in figure), from And some distinguished function characteristics can be brought, including location of moisture detection function.

The wet detection zone of the urine of the embodiment of the present invention and stool detection zone are distinguished there is no stringent, in practical applications, size Just may also can interpenetrate, but having any is affirmative, be exactly moist position more rearward, a possibility that being caused by stool, is just It is bigger that (note: the stool detection function of the embodiment of the present invention is mainly needle baby user, and infant faeces water content is larger, foot The position of electrode 125,126 is reached to moisten permeable braid layer 18 and enables two electrodes that short circuit occurs).In order to realize that position is examined It surveys, the printing of low-resistance carbon electrically conductive ink can be used in the electrode 121,122 of embodiment one, (is, for example, less than with lesser resistance 100 kilohms)；At the same time, the electrically conductive ink printing of high electrical resistance value can be used in the electrode 125,126 of the embodiment of the present invention, Its resistance (such as several megohms) with higher, the resistance in such circuit are mainly reflected on 125,126 this two segment electrode, Enable the resistance variations of electrode 125,126 that can be easier to be detected.

Below referring to figure 2. shown in, this be a kind of location of moisture of sense electronics wet absorption articles embodiment one of the present invention with Loop resistance relation curve schematic diagram.Horizontal axis is distance d in figure, corresponds to location of moisture and the first, second absorption region demarcates The distance between line 150 (terminal of line of demarcation 150 and third flexible electrode 125, the 4th flexible electrode 126 in Fig. 1).The longitudinal axis It is resistance r, is the resistance value in entire circuit.When distance d is 0 or negative, r is infinitely great (open circuit of electrode 125,126), represents the Two absorption regions 152 are dry and comfortable.At the section 0-Da, humidity gradually drenches the area A (152a) d since line of demarcation 150, circuit Resistance drops to Ra (short-circuit resistance for ignoring moist generation) from R0.Similarly, after with the diffusion of liquid and location of moisture It moves in (from the area A to the area B again to the area C), resistance r can further fall to Rb from Ra, be finally Rc (when A, B, C are dripping wet).In reality In the application of border, when the loop resistance r detected smaller (closer to Rc), then judge that the probability defecated is bigger.

It can see from above-mentioned curve, under the effect of the moist short circuit in the second absorption region, the third of the embodiment of the present invention Flexible electrode 125 and the 4th flexible electrode 126 can produce one by preceding (area the A) resistance that (area C) gradually successively decreases backward, this knot Structure, which is enabled, judges that location of moisture is possibly realized by the resistance detection in circuit, thus can realize the differentiation of stool and urine.

Below referring again to shown in Fig. 3, this is that a kind of Section A-A of sense electronics wet absorption articles embodiment one of the present invention shows It is intended to.It is apparent that absorbed layer 15 is enclosed within waterproofing membrane 11 and permeable braid layer 18 in figure, and on both sides It include the first flexible electrode 121, the second flexible electrode 122 and in absorbed layer 15 and permeable braiding in free from dampness safety zone It include third flexible electrode 125 and the 4th flexible electrode 126 between nitride layer 18,.When having moist excretion in the second absorption region In the presence of object (such as stool of baby) 17, the moisture for including in 17 can pass through permeable braid layer 18, and electrode 125,126 is short Road, resistance variations can refer to aforementioned curve shown in Fig. 2.

Shown referring to figure 4. below, this is a kind of structural schematic diagram of sense electronics wet absorption articles embodiment two of the present invention. Compared with previous embodiment one, the embodiment of the present invention two includes a short-circuit line 123, by two at the endpoint of electrode 125,126 Electrode is shorted together.For aspect description, the electrode that 125,123 and 126 are constituted is known as the U-shaped electricity of the first high resistant by embodiment two Pole, the position of short-circuit line 123 are known as the bottom of U-shaped electrode, be directed toward absorbent item 10 middle position (in figure with first, the Starting point of the line of demarcation 150 of two absorption regions as U-shaped bottom (inward flange))；The position of electrode connection points 127,128 is referred to as U-shaped The opening of electrode is directed toward the back-end location of absorbent item 10.The major function of short-circuit line 123 is enabled based on U-shaped electrode The first resistor measure loop of body generates a detectable initial resistivity value (R0), which is much larger than Regular Human's excreta The short-circuit resistance generated when acting on (infiltration) U-shaped electrode.Embodiment two monitors first electricity based on the initial resistance The resistance variations in 10 use process of absorbent item for hindering measure loop, would know that the dampness of the quantization of absorbent item 10 Information, and location of moisture detection is enabled to calculate more accurate, circuit structure the opening compared with embodiment one of this closed loop of embodiment two Loop circuit structure has significant progress.Because being printed on waterproofing membrane 11 and permeable braid layer 18 using carbon electrically conductive ink Resistance have very big uncertainty (error that 50% can be had more than), when the type of resistance value and ink, concentration and printing The factors such as temperature, speed it is related, if it is not known that the initial resistivity value in circuit, is likely to result in the mistake of location of moisture judgement Accidentally.The location of moisture of embodiment two detects and moist degree detecting function can make following summing-up description:

When the slop for including electrolytic liquid is injected from absorbed layer upper surface middle position, the suction Receive articles occur it is moist and to external diffusion, including from U-shaped electrode base to U-shaped electrode opening from spread, the electrolytic liquid U-shaped electrode short circuit since bottom is enabled, and the short dot can add with the increasing of moist degree gradually to opening Mobile, the resistance for enabling the first resistor measure loop from large to small, can determine whether the humidity according to the size of the resistance Degree.

Below referring to figure 5. shown in, this be a kind of location of moisture of sense electronics wet absorption articles embodiment two of the present invention with Loop resistance relation curve schematic diagram.Horizontal axis is distance d in figure, correspond to location of moisture and U-shaped electrode base (inward flange) it Between distance.The longitudinal axis is resistance r, is the resistance value in entire circuit.When distance d is 0 or negative, loop resistance value is R0 (in reality Apply in example one, r is infinity in the case where no short-circuit line), it is dry and comfortable for representing the second absorption region 152.In the area 0-Da Between, moist gradually to drench the area A (152a), loop resistance drops to Ra from R0.Similarly, moving back (from the area A with location of moisture The area C is arrived again to the area B), resistance r can further fall to Rb from Ra, be finally Rc (when A, B, C are dripping wet).In practical applications, When the loop resistance r detected smaller (closer to Rc), then judge that the probability defecated is bigger.

It is please referred to shown in Fig. 6 below, this is a kind of structural schematic diagram of sense electronics wet absorption articles embodiment three of the present invention. Absorbent item 10 includes an independent permeable braid layer 16 in figure, and in addition to this, other parts and embodiment are second is that one Sample.In example 2, third flexible electrode 125 and the 4th flexible electrode 126 are to be printed on permeable 18 following table of braid layer On face, since permeable braid layer 18 is more loose, it is less susceptible in the printed thereon conductive oil line of ink marker, and due to permeable volume Tissue layer 18 can touch the skin of user, in order to avoid electrically conductive ink penetrates into upper surface and the skin of permeable braid layer 18 Skin contact, can be used and be first printed on the conductive oil line of ink marker on the lower surface of the permeable braid layer 16 of one suitable independence, then 16 are placed between absorbed layer 15 and permeable braid layer 18 again, and by 16 in free from dampness safety zone with waterproofing membrane 11 and Permeable braid layer 18 bonds, and enables electrode 125,126 be electrically connected with electrode 121,122 and generates tie point 127,128, this is visual For a modified version to the embodiment of the present invention two.

It is please referred to shown in Fig. 7 below, this is a kind of structural schematic diagram of sense electronics wet absorption articles example IV of the present invention. In figure absorbent item 10 in addition to be made of flexible electrode 121,122,125,126 and short-circuit line 123 first resistor measure loop it It outside, further include having second resistance measure loop, the second resistance measure loop is arranged in flexible water film 11 towards absorption On the upper surface of layer 15, directly contacted with the lower surface of absorbed layer 15, it can be achieved that the lower surface to the second absorption region 152 is moist Detection, this is to detect to the first resistor measure loop of the embodiment of the present invention three to 152 upper surface humidity of the second absorption region One supplement.

Specifically, the second resistance measure loop include at least one the 5th flexible electrode 131, it is at least one the 6th soft Property electrode 132, the five, the 6th flexible electrode are located at the interior edge of aforementioned first flexible electrode 121, the second flexible electrode 122, With 121,122 move towards identical, position and shape is similar.It is reached by the free from dampness safety zone of annular from the first safety zone The rear end part (the second safety zone) of paper diaper, then it is flexible at least one the 7th flexible electrode 135 and at least one the 8th The electrical connection of electrode 136 generates tie point 137,138, and then another short-circuit line 133 is again in the line of demarcation of the first, second absorption region By 135,136 short circuit of electrode on position, resistance detection circuit (135,133,136 the second high resistant U of composition of another closed loop are formed Type electrode).In order to realize location of moisture detection function, electrode 131,132 is using low-resistance carbon electrically conductive ink in waterproofing membrane 11 Upper surface printing towards absorbed layer 15, and the carbon electrically conductive ink that electrode 135,136 uses resistance value relatively high is in waterproof Film 11 is printed towards the upper surface of absorbed layer 15, and the dominant resistance in circuit is enabled all to concentrate on electrode 135,136, when humidity will When 135,136 short circuit of electrode, as long as the resistance value in measure loop, moist location of short circuit can be calculated, this is electric with first It is similar for hindering the algorithm of measure loop.Furthermore also can be by the width or thickness of the reduction conductive oil line of ink marker 135,136, or pass through The modes such as adjustment printing plate cylinder parameter, Ink parameters increase its resistance value.

The U-shaped electrode of first and second high resistant is similar in shape in appearance, but the detection emphasis of the two is different.? Within the scope of second absorption region 152, the U-shaped electrode of the first high resistant is configured on permeable 18 lower surface of braid layer, with suction The upper surface for receiving layer 15 is in contact；And the U-shaped electrode of the second high resistant is configured on the upper surface of waterproofing membrane 11, with absorbed layer 15 Following table face contact.By first and second resistance detection circuit to the resistance detection of the U-shaped electrode of first and second high resistant, The moisture conditions of the upper surface and the lower surface of absorbed layer 15 can be known respectively, this is conducive to analysis and distinguishing in second uptake zone Humidity in domain 152 is wet caused by urinating, or as caused by defecating, thus can realize the stool and urine detection of absorbent item 10 And distinguish function.

It is please referred to shown in Fig. 8 below, this is a kind of section B-B signal of sense electronics wet absorption articles example IV of the present invention Figure.11 be flexible water film in figure, and 18 be permeable braid layer, 15 be include absorbed layer between 11 and 18.19 for into Enter the conducting liquid (electrolytic liquid, such as urine) in the second absorption region 152, due to the effect by gravity, urine is downward Accumulation, can by configuration 11 upper surface of waterproofing membrane (towards absorbed layer 15) the 7th flexible electrode 135 and the 8th flexible electrode 136 short circuits, enable the resistance value of second resistance measure loop reduce.

17 be the semisolid humidity excreta (such as baby stool) on the second absorption region 152 in figure, due to defecating not It is liquid, permeable braid layer 18 can not be passed through, but includes that moisture in 17 can cross permeable braid layer 18, and will print Third, 125,126 short circuit of the 4th flexible electrode on 18 lower surface of braid layer, enable the resistance value of first resistor measure loop Reduce.

It can be seen that, first resistor measure loop is mainly for detection of the stool in the second absorption region from the above analysis (semisolid excreta), and second resistance measure loop is mainly for detection of urine (the liquid row in the second absorption region of detection Let out object).If 17 include liquid it is relatively more (urine+stool), the resistance in the first, second resistance detection circuit all can be because of liquid Short circuit and resistance becomes smaller, but because liquid flow from top to bottom, the resistance of first resistor measure loop can become smaller first, so The resistance for being only second resistance measure loop afterwards becomes smaller, the rule for having a sequencing to change, by above-mentioned first, second The resistance variations situation (size and precedence) in resistance detection circuit is analyzed, and can infer the correlation circumstance of excreta, Specifically there are also further descriptions in following legend.

It is please referred to shown in Fig. 9 below, this is a kind of structural schematic diagram of sense electronics wet absorption articles embodiment five of the present invention. Flexible water film 11, permeable braid layer 18 in figure, and include the first absorption region 151, second absorption in 11,18 Region 152 constitutes the main part of absorbent item 10.Further, absorbent item 10 further includes the first flexible electrode 121, Two flexible electrodes 122 and third flexible electrode 125, the 4th flexible electrode 126 and short-circuiting electrode 123 (constitute the first high resistant U Type electrode), above-mentioned electrode constitutes the first resistor measure loop of the embodiment of the present invention, the structure of these and previous embodiment four It is similar.

In place of the main difference of example IV, it is that the second measure loop of embodiment five is that have quantization urine wet by one What the capacitance detecting circuit of detection function was constituted comprising be printed on 11 lower surface of flexible water film (backwards to absorbed layer) 9th flexible electrode 141 and the tenth flexible electrode 142 being printed on 11 upper surface of flexible water film (towards absorbed layer).Electricity Flexible water film 11 between pole 141,142 and electrode constitutes a capacitor.When absorbent item 10 is dry condition When, the size of fixed initial resistance a C0, the C0 area opposite with electrode 141,142 can be presented between electrode 141,142 It is directly proportional.Since 142 width is narrower than 141 very much, the numerical values recited of C0 is directly proportional to 142 width.When absorbent item 10 has It include that urine in absorption region 151,152 is in contact and with 142 in equipotential state with electrode 142 when urinating wet generation (because urine be conducting electrolyte), this width equivalent to increase electrode 142, is detected between electrode 141,142 to enable To capacitance increase, therefore whether absorbent item 10 can be detected by the method for capacitance between detection 141,142 It is wet by urinating, and how urinate wet degree.

It is please referred to shown in Figure 10 below, this is that a kind of section C-C of sense electronics wet absorption articles embodiment five of the present invention shows It is intended to.Electrode 121,122,125,126,123 (not indicating in figure) constitutes first resistor measure loop, it can be achieved that absorbed layer 15 The moist detection of upper surface, and 141,142, electrode constitute the capacitance detecting circuit that wet detection function is urinated with quantization, it can be real The moist detection of existing 15 lower surface of absorbed layer.Electrode 141 is configured in the lower surface (backwards to absorbed layer 15) of waterproofing membrane 11 in figure, Its wider width.Electrode 142 is configured in the upper surface (towards absorbed layer 15) of waterproofing membrane 11, narrower width.Absorbed layer 15 The electrolytic liquid 19 (urine) of lower surface is in contact and with 142 in equipotential state with electrode 142 as electrolyte, at this moment Liquid 19 is quite an equivalent liquid electrode in this capacitance detecting circuit, and the width of electrode 142 is widened, 141, Capacitor between 142 also increases therewith.In this case, waterproofing membrane 11, electrode 141, electrode 142, liquid 19 are constituted One sensu lato nonpolarity variable electrolytic capacitor, wherein 121,122 be two electrodes of electrolytic capacitor, 11 be electrolysis The dielectric of capacitor, 19 be the electrolyte of electrolytic capacitor.In this electrolytic capacitor, in capacitance and absorbed layer 15 Electrolyte 19 content it is related, 19 content of electrolyte is more, shared by bigger (the especially lower surface tide of absorbed layer 15 of area Wetted surface, including transverse width and longitudinal length), the capacitance of the electrolytic capacitor is bigger.

It is please referred to shown in Figure 11 below, this is a kind of sense electronics wet absorption articles example IV of the present invention in the second uptake zone The first, second resistance detection loop resistance change curve schematic diagram when domain has stool excretion to happen.Abscissa is in figure Time t, ordinate are loop resistance value r, and r1 is the resistance value of first resistor measure loop, and r2 is second resistance measure loop Resistance value.In the dry and comfortable situation of absorbent item 10, the resistance value (initial resistivity value) of first resistor measure loop is R10, second The resistance value (initial resistivity value) in resistance detection circuit is R20, it is assumed that has stool excretion situation in the second absorption region in T1 Occur, semisolid excreta 17 is covered on permeable 18 upper surface of braid layer, and moisture, which enables, to be arranged in permeable braid layer Short circuit, R11 when resistance r1 being enabled to drop to T2 from initial value R10 occur for the electrode 125,126 of 18 lower surfaces.Simultaneously with this, The numerical value that the resistance value r2 in two resistance detection circuits then maintains always R20 is constant, because the moisture of semisolid excreta 17 is not It is more, absorbed layer 15 can not be passed through and reach bottom, the resistance of second resistance measure loop is enabled to become smaller.This r1, r2 resistance variations rule Rule is that a situation arises than more typical stool, and resistance r1 changes bigger (i.e. resistance value becomes smaller), it was demonstrated that the position of excreta 17 Set more rearward, and it is also bigger to be confirmed as stool odds.

It is please referred to shown in Figure 12 below, this is a kind of sense electronics wet absorption articles example IV of the present invention in the second uptake zone The first, second resistance detection loop resistance change curve schematic diagram when domain has urine excretion to happen.Not with Figure 11 situation Together, the initial value of the resistance value r1 of first resistor measure loop is R10, is reduced since T1 (urination), is reduced when to T2 To R11.Simultaneously with this, the resistance value of r2 reduces by initial value R20 since T3, until R21 is reduced to when T5, and the resistance of r1 Then from R12 when being begun to ramp up when T4 (urination stop) and reaching T6.

Above-mentioned curvilinear motion illustrate to enable the second absorption region it is moist be liquid urine rather than semisolid stool because Liquid enters from permeable braid layer 18 to enable the resistance of first resistor measure loop become smaller first, then reach absorbed layer 15 Bottom enables the resistance of second resistance measure loop become smaller again.Due to the effect of gravity, the liquid of 15 bottom of absorbed layer is more and more, It enables r2 resistance more become smaller.The liquid on 15 upper layer of absorbed layer is then fewer and fewer at the same time, and r1 resistance is enabled to change from small to big, thus Show curvilinear motion pattern shown in Figure 12.

It is please referred to shown in Figure 13 below, this is a kind of present invention sense electronics wet absorption articles embodiment five in the second uptake zone First resistor measure loop resistance variations and capacitance detecting tank capacitance change curve when domain has urine excretion to happen are shown It is intended to.Horizontal axis is time t in figure, and the longitudinal axis is the resistance r of first resistor measure loop and the capacitor c in capacitance detecting circuit.It is inhaling It receives in the dry and comfortable situation of articles 10, the initial resistance of first resistor measure loop is R0, and the initial capacitance value in capacitance detecting circuit is C0.When T1 has urine excretion to happen in the second absorption region, the resistance of r starts to become smaller, and reaches low ebb in T2, Then at T3 (urine terminates), resistance is begun to ramp up, the resistance variations rule of this and the first resistor measure loop in earlier figures 12 Rule is the same.

With example IV the difference is that capacitance detecting circuit in the embodiment of the present invention five, the capacitance c since T2 It begins to ramp up, it is meant that begin with liquid accumulation and more and more in 15 bottom of absorbed layer, and when urine terminates one section of (T3) Between after (T4) stop rise and rest on the position of numerical value C1.It notices r to begin to ramp up in T3 (urine terminates), exist than c At T4 stop rise time will be earlier, it is meant that liquid reach absorbed layer bottom and start accumulation need it is some more when Between.By the analysis to above-mentioned resistance and capacitance variations rule, the stool and urine excretion situation of user would know that.

It is please referred to shown in Figure 14 below, this is a kind of present invention sense electronics wet absorption articles embodiment five in the second uptake zone First resistor measure loop resistance variations and capacitance detecting tank capacitance change curve when domain has stool excretion to happen are shown It is intended to.Horizontal axis is time t in figure, and the longitudinal axis is the resistance r of first resistor measure loop and the capacitor c in capacitance detecting circuit.It is inhaling It receives in the dry and comfortable situation of articles 10, the initial resistance of first resistor measure loop is R0, and the initial capacitance value in capacitance detecting circuit is C0.Assuming that having stool excretion to happen in the second absorption region in T1, semisolid excreta 17 is covered on permeable braided fabric 18 upper surface of layer, moisture enable the electrode 125,126 that permeable 18 lower surface of braid layer is arranged in that short circuit occurs, enable resistance R1 when r drops to T2 from initial value R0, and the numerical value of C0 is maintained always not with the capacitance c in this while capacitance detecting circuit Become, because the moisture of semisolid excreta 17 is few, absorbed layer 15 can not be passed through and reach bottom, enable the capacitor in capacitance detecting circuit Value becomes larger.This r, c changing rule is that than more typical stool, a situation arises, and bigger (i.e. resistance value is got over for resistance r variation It is small), it was demonstrated that more rearward, it is also bigger to be confirmed as stool odds in the position of excreta 17.

It is please referred to shown in Figure 15 below, this is a kind of present invention sense electronics wet absorption articles embodiment five in the first uptake zone First resistor measure loop resistance variations and capacitance detecting tank capacitance when domain has larger amount of urine excretion to happen become Change curve synoptic diagram.The first resistor measure loop of the embodiment of the present invention only detects the moist feelings of the second absorption region in principle Condition, but due to the first, second absorption region be not it is absolutely separated, when the liquid of the first absorption region is more, will seep It penetrates among the second absorption region, also the resistance of first resistor measure loop can be enabled to change.

The variation of resistance r and capacitor c just illustrate this case in figure.Since the capacitance detecting of the embodiment of the present invention is returned Road is for entire absorbent item, including the first absorption region 151 and the second absorption region 152.In T1, c is begun to ramp up (urination) starts to remain unchanged (urination stops) in T2；Then rising (urinating again) is started again in T3, and in T5 After remain unchanged (urination stop).During T1-T3, it is constant that r numerical value maintains always initial value R0, illustrates that urine does not occur to exist Second absorption region.Become smaller r since T4, since its speed that becomes smaller is slower, slope is lower, and occurs to arrange at second During urine, this urine for being regarded as the first absorption region penetrates into one of the second absorption region as a result, rather than inhaling second Receiving region has the occurrence of stool, urine excretion.

It is please referred to shown in Figure 16 below, this is a kind of present invention sense electronics wet absorption articles embodiment five in the second uptake zone First resistor measure loop resistance variations and the variation of capacitance detecting tank capacitance are shown when domain has stool and urine excretion to happen simultaneously Meaning.It may know that the resistance of first resistor measure loop has a greater change in some moment according to the analysis of related legend before, And its numerical value is remained unchanged in low level or is not rebounded, and can be considered as has stool to happen；And the capacitor in capacitance detecting circuit Value has increase, just proves the generation for having urination.Above-mentioned curve is believed that during T1-T3 while having the feelings of stool and urine Condition enables r reduce (and holding) and c increasing, and only stool happens r is enabled to further decrease (and c numerical value during T4-T5 It remains unchanged).All relevant urination defecation information are substantially all and can be obtained by the analysis on change to r and c curve.
