Description

Alarm device for urine wet

The utility model is that a kind of infant of being used for urinates wet clothing and bed-wetting and ill old man, the alarm device for urine wet the when paralytic drowns urine.

No. 92201831.6 documents of Chinese patent disclose a kind of " baby's urinating attention device ", it is connected and composed with lead by probe, resistance, music integrated circuit block, light emitting diode, piezoelectric ceramic piece, button cell, and the cushion compound or the flexible plastic sheet that stamp conduction seal material are made probe and made power switch with low-power transistor.This kind structure causes this patent to have following defective: the one, and low and easy damage of the manufacturing process complexity of probe and mechanism's intensity; The 2nd, can fail to report phenomenon than the small property life because of the conductive coating of probe, the 3rd, adopt the triode energized and on the collector of this pipe, insert resistance, volume can reduce and the possibility distortion, and is also influential to the reliability that triggers simultaneously.

The purpose of this utility model is to provide a kind of alarm device for urine wet of making simple, easy to use and good reliability.

The purpose of this utility model is achieved in that it is made up of two conductive rubber electrodes and the voice controller that is attached thereto, this electrode stationary arrangement is on the General Purpose Rubber substrate, and voice controller is formed by control circuit, CMOS speech chip Y with the playback circuit that triode T promotes loudspeaker B.

The spacing of above-mentioned two conductive rubber electrodes can be 2-50mm, and after surpass 50mm, electrode is reliable sensing just.Our experiments show that, be best with the spacing of 10mm.Both areas are at least respectively 3-5mm ², the reliability of electrode is along with the corresponding improve of the increase face of area in general.

Above-mentioned control circuit can be made up of resistance, a not gate, also can be made of the oscillator that can also be made up of two not gates, resistance and electric capacity and be made up of these two parts of circuit that resistance, a rejection gate are formed a resistance.This control circuit can promote the signal triggering speech chip of electrode sensing loudspeaker by triode and emit music or warning message such as " urine are wet " again.

The utility model has the advantages that

One is to use object wide, and infant, paralytic and ill old man all can use.

The 2nd, profile is small and exquisite, solid, is convenient to wear, thereby helps in bed or children's creeps, use when playing, and also can not influence result of use because of children's's rolling in bed.

The 3rd, warning is sensitive, trigger action is reliable, in case urine is wet, just can in time report to the police.

The 4th, electrode life is long, and is not fragile.And, simple in structure, be convenient to make.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of conductive rubber electrode 1 among Fig. 1.

Fig. 3, Fig. 4, Fig. 5 are respectively the circuit theory diagrams of voice controller 5 among Fig. 1.

As shown in Figure 1, the utility model is formed by two conductive rubber electrodes 1 with by the voice controller 5 that high strength lead 4 is attached thereto.These two electrode spread are on General Purpose Rubber substrate 2, and its spacing is 2-50mm, are best with 10mm.The area of each electrode is decided according to using object, but is 3-5mm at least ², its shape is oval or circular or other shape (as the grizzly bar shape).During making, imbed in the substrate for one section of the lead 4 that will link to each other in advance, and the end of lead is exposed, exposed the end of a thread is sealed (see figure 2), two electrode mutually insulateds that make it to arrange on substrate with conductive rubber with electrode.For two electrodes are fixed on the substrate better, can also pass that fixed orifice 3 ties up to or not on trousers with rope or safety pin, during use, only need contact and get final product with common yarn fabric.In the housing of voice controller 5, be provided with control circuit, CMOS speech chip Y and promote the circuit of loudspeaker B playback with triode T.

Fig. 3 has shown the circuit theory in the voice controller 5.As shown in Figure 3, control circuit is made up of resistance R and not gate U.R and U input end, an electrode connect altogether.U output termination speech chip Y trigger end, Y output termination triode T base stage, the T collector meets loudspeaker B.The other end of R and B, Y positive power source terminal connect power supply E positive pole altogether, and another electrode, Y negative power end, T emitter connect the E negative pole altogether.Y is a high level continuous trigger element among the figure.If being low level, triggers Y, then not gate U changes a buffered gate into, or changes the wiring of the resistance R and the electrode other end, is about to the anodal R one end reconfiguration E negative pole that links to each other with E, the electrode reconfiguration E positive pole that links to each other with the E negative pole, these two kinds of methods all can realize the triggering to Y.

For the speech chip Y that meets inner supreme that draw resistance, low level continuous trigger or inner no pull down resistor, high level continuous trigger, the control circuit of its triggering can be finished by a resistance R.As shown in Figure 4, low level Y trigger end and R one end, an electrode connect altogether.The R other end, Y positive power source terminal, loudspeaker B one end connect power supply E positive pole altogether.Y output termination triode T base stage, the T collector connects the B other end.Another electrode, Y negative power end, T emitter connect the E negative pole altogether.For the Y of high level continuous trigger, connection gets final product only to need to exchange the resistance R among Fig. 4 and another electrode once, is about to the anodal R one end reconfiguration E negative pole that links to each other with E, an electrode reconfiguration E positive pole that links to each other with the E negative pole.

For pulsed speech chip Y, its control circuit is made up of vibration and control two parts circuit as shown in Figure 5.The same prior art of oscillatory circuit is by not gate U ₁, U ₂And resistance R ₁, R ₂And capacitor C is formed.The control section circuit is by R ₃, rejection gate U ₃Form.Wherein, R ₃Meet an electrode and U ₃An input end, U ₃Another input termination U ₂Output terminal.R ₃The other end, Y positive power source terminal, loudspeaker B one end connect power supply E positive pole altogether.U ₃Output termination Y trigger end, Y output termination triode T base stage, the T collector connects the B other end.Another electrode, Y negative power end, T emitter connect the E negative pole altogether.

R among resistance R and Fig. 5 among Fig. 3, Fig. 4 ₃Resistance value can select 1-20M Ω for use, occurrence can trigger the sensitivity of reporting to the police to change according to respective change such as the size of conductive rubber electrode area, shapes.Speech chip Y can select HT for use in the accompanying drawing _-813Or MSS _-582The type Music Clip perhaps can send speech chip FH such as " urine is wet ", " I urinate wet " _-122Not gate U, U ₁, U ₂Can select CD for use ₄₀₁₁, CD ₄₀₆₉, ₁₄HC ₀₄With ₇₄HC ₀₀Etc. model, rejection gate U ₃Model can be CD ₄₀₀₁Or ₇₄HC ₀₂Deng.

The course of work of the present utility model is: after clothing, bed are wet by urine, conductive rubber electrode 1 passes to signal in the voice controller 5, trigger CMOS speech chip Y by control circuit, promote loudspeaker B through triode T again and send music or audio alert signals such as " urine is wet ", " I urinate wet ", till turning off power supply or changing the wet fabric of urine.
