Abstract
A computer urine alarm for babies belongs to the field of daily necessities. It includes a music integrated circuit and a loudspeaker. This novel two electrodes of two-sided copper-clad printed circuit board formula sensor put on baby's diaper as the switch, and when the baby urinates, the sensor electrode switches on, and the power adds on integrated circuit, and the music integrated package during operation drives the speaker sound production and reports to the police. The utility model has simple structure and is suitable for household use of the support and the newborn.
Description
This utility model belongs to daily life tools, is specially adapted to a kind of baby's dung urine alarm device.
Existing urinating alarm, the humidity sensor sensitivity adjustment of utilization is poor, and the aridity of diaper itself also can cause warning inadequately, causes error signal, and it is poor that audio frequency, volume are adjusted property in addition, uses inconvenient.Useful discrete component assembling, cost height, chimes of doom dullness, with the piezoelectric ceramic piece pronunciation, sound is too little, the cost height, no anti-tampering merit electric capacity on the circuit can false triggering.
It is simple that the purpose of this utility model provides the strong circuit of a kind of sensitivity, audio frequency and audio frequency adjustability, baby's computer urine-wet alarm with low cost.
The purpose of this utility model can realize by following measure, pin one at music integrated circuit IC, connect on 6 and have the sensors A of two electrodes, be connected in the pin 5 of IC after sensitivity adjustment resistance R 1 and the anti-interference capacitor C1 parallel connection, on 6, rhythm is adjusted the pin two that resistance R 3 is connected IC, on 3, battery is connected on the pin one of IC, on 5, the base stage of crystal triode BG is connected on the pin 4 of integrated circuit, the emission collection of audion BG is connected on its pin 5, is connected on the IC pin one after the collector terminal of audion BG series connection speaker Y and the output volume adjusting resistance R 2.
Sensors A is that two-sided deposited copper printed circuit board (PCB) constitutes, and its electrode 1 and 2 dentations for engagement apply copper face.
Fig. 1 is a circuit structure diagram of the present utility model.
Fig. 2 is the structure chart of pick off.
This novel structure as shown in the figure, when between the electrode 1 and 2 of vane certain moisture content being arranged, circuit is connected, speaker Y sends musical sound, during use, pick off is put into baby's diaper, in case baby's piss, two resistance between electrode are reduced, when being lower than the resistance setting, triggering music integrated circuit and make speaker Y send musical sound.Because of pick off is two-sided deposited copper printed circuit power, two-sidedly all can effectively use, and volume is little, draws materials conveniently, cost is low.Resistance R 1 is for adjusting transducer sensitivity resistance, and resistance is the Da Yi false alarm too, elects as about 60k to good.Capacitor C 1 is provided with for anti-electromagnetic interference false triggering; Resistance R 2 output volume adjusting resistance, resistance and output volume are inversely proportional to, and resistance R 3 is adjusted resistance for the rhythm speed, and the resistance that reduces resistance R 3 can increase performance speed.
Adopt this urine-wet alarm, can make baby father and mother or nursery school aunties changing babies' napkin more in time, with the hip of avoiding the baby and pudendum because of soaking the rubescent or phenomenon of festering with dung urine for a long time.
This novel circuit is reasonable in design, and is simple in structure, with low cost, and result of use is good, and particularly suitable nursery school and newborn baby are used.
Claims (2)
1, a kind of baby's computer urine-wet alarm, the pin one, 6 connections that it is characterized in that music integrated circuit IC have the sensors A of two electrodes, on the pin 5,6 that sensitivity adjustment resistance R 1 in parallel and anti-interference capacitor C1 are connected IC, rhythm is adjusted resistance R 3 and is connected on the pin two, 3 of IC, battery is connected on the pin of IC on 1,5, the base stage of crystal triode BG is connected on the pin 4 of integrated circuit, is connected on the pin one of IC after the collector terminal series connection sound device Y of audion BG and the output volume adjusting resistance R 2.
