Abstract

The utility model relates to a urinal pad only alarming for a baby's feces, comprising a seepage pad made of permeable cloth and a delay alarm with three electrodes, wherein, the electrodes 1 and 2 are arranged on the surface of the seepage pad, while the electrode 3 is arranged on the bottom surface of the seepage pad; the electrodes 1 and 3 are connected with the electric source of the alarm, while the electrode 2 is connected with the trigger electrode of an integrated circuit block in the alarm. When the urinal pad is wetted by urine, the electrodes are switched on; because of the small separation distance between the electrodes 2 and 3 as well as small resistance, the alarm does not work, according to a partial pressure principle; when the urinal pad is pressed by the feces, the electrodes 2 and 3 are not switched on, and then the alarm works.

Description

Baby shit reporting cushion

This utility model relates to a kind of urine pad that can report to the police to baby stool.

At present, the sepage pad that a kind of " diaper " infant urine spacer of selling on the market has a water penetration fabric to make solving after baby's urine the problem without changing babies' napkin, but can't be reported to the police greatly after an action of the bowels and changes the urine pad as the baby.

The purpose of this utility model is improved and is provided a kind of baby stool that can report to the police greatly after an action of the bowels the baby report pad above-mentioned prior art.

The solution that realizes this utility model purpose is: the baby stool that is provided is reported the sepage pad that spacer has a water penetration fabric to make, and also is provided with a delayed alarm device of being made up of three electrodes, sound chip, the delay capacitor that links to each other with sound chip and sounding component in addition.Wherein two electrodes 1,2 are located at the surface of sepage pad, another electrode 3 is located at the bottom surface of sepage pad, electrode 1 extremely links to each other with the power supply of aforementioned chip respectively with electrode 3, electrode 2 links to each other with the trigger electrode of chip, and the distance that distance that electrode is 1,2 and electrode are 1,3 is all greater than the distance of 2,3 at electrode.

Below in conjunction with accompanying drawing content of the present utility model is described in detail.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is one of sectional drawing of this utility model urine pad part.

Fig. 3 is two of this utility model urine pad sectional drawing partly.

Fig. 4 is overall structure figure of the present utility model.

As shown in Figure 1: the top layer of urine pad 4 is a sepage pad 5, make by the warp knitting nap fabric, its bottom surface place mat one deck common cotton weave cotton cloth or the article of toilet paper and so on as liquid storage pad 6.Electrode 1,2 is positioned at the surface of sepage pad 5, and electrode 3 is located at the bottom surface of sepage pad 5; Electrode 1,3 links to each other with the power supply positive and negative electrode of sound chip 7 respectively, and electrode 2 links to each other with the trigger electrode of chip 7, and delay capacitor 8 and piezoelectric ceramic piece 9 are connected on respectively on the trigger electrode and output stage of chip 7.When the trigger electrode voltage of chip 7 during more than or equal to 1/2nd supply voltages, signal output is arranged, piezoelectric ceramic piece 9 sounding alarms, otherwise, the output of chip 7 no signals.After urine pad 4 was soaked, 2,3 at 1,2 at electrode and electrode were equivalent to connect a resistance R ₁, R ₂, (as shown in phantom in FIG.).At this moment, the trigger electrode voltage of chip 7 is by resistance R ₁, R ₂Obtain resistance R after the dividing potential drop ₁, R ₂Size by electrode spacing and the decision of urine pad humidity.When the baby does not have large and smallly just the time, each electrode is in open-circuit condition, the output of chip 7 no signals.When the baby only urinated, each electrode was switched on, because of the spacing of electrode 1,2 greater than electrode 2,3 spacings, so the resistance R of 1,2 at electrode ₁Resistance R greater than 2,3 at electrode ₂, i.e. R ₁＞R ₂, the trigger electrode voltage of integrated package 7 is less than 1/2nd supply voltages, and integrated package 7 no signals are exported.Piezoelectricity pottery sheet 9 is sounding not.At this moment, this urine pad is just the same with the effect of aforementioned existing " diaper " urine pad, and urine will see through sepage pad 5 very soon and enter liquid storage pad 6, makes urine pad surface be in drying regime.In the moment of baby's urine, electrode 2,3 might not can be switched on immediately, then resistance R ₁＜R ₂, but since the time-lag action of electric capacity 8 make and between time delay, false alarm can not take place.Delay time can be chosen in the several seconds, and urine can be connected electrode 2,3 to see through the sepage pad completely during this period, makes resistance R ₁＞R ₂And do not report to the police.When the baby only defecated, stool was connected electrode 1,2, but can not see through sepage pad 5, and electrode 2,3 is obstructed, interelectrode resistance R ₁＜R ₂, piezoelectric ceramic piece 9 sounding alarms.Simultaneously large and small just the time as the baby, beginning is because the time-lag action of electric capacity 8 and can not reporting to the police, and time-delay is later because urine enters following liquid storage pad 6 gradually, and the humidity of sepage pad 5 is more and more littler, and promptly the resistance of 2,3 at electrode increases gradually, works as R ₁〉=R ₂The time, piezoelectric ceramic piece 9 sounding alarms.

Above-mentioned each electrode can adopt conduction cloth or conductor wire.The position of electrode 3 can be positioned at the side (see figure 2) or the outer side (see figure 3) of electrode 2, but preferably with electrode 2 relative (see figure 1)s.Electrode 1,2 can be fixed on the demountable water penetration fabric gauze 10, so that change washing.

Overall structure of the present utility model as shown in Figure 4.Each electrode divides two-way to be arranged in parallel on the urine pad 4, and each electronic component is contained in the box 11, and each electrode links to each other with integrated package in the box 11 by metal sublayer box 12.

Of the present utility model simple in structure, have the dual-use function that need not change the urine pad and can report to the police after an action of the bowels greatly after urine wets.This utility model is mainly used in baby, child, also can be used for the nursing of some especial patient.
