Abstract

The utility model discloses a urinating alarm, which is characterized in that: a delay circuit is arranged between a humidity sensitive probe and a music integrated block, and connected to a power. The utility model is provided with the delay circuit arranged between the humidity probe and the music integrated block, and the delay circuit can delay the signal transferred from the humidity sensitive probe for a plurality of minutes, which can prevent a baby from being terrified by the music for the device does not alarm immediately after the urinating of the baby, so the diaper can be timely replaced and the replacement times of the diaper can be reduced, which is very beneficial to physical and mental health of the baby.

Description

Urine-sounding instrument

Technical field:

The utility model relates to the technical field of electronic instrument, specifically a kind of Urine-sounding instrument that is mainly used in the baby.

Background technology:

Though existing Urine-sounding instrument can send musical sound after baby' diaper urine is wet, reminds people is in time changed, eliminated the hidden danger of infections in infants diaper rass, but its circuit structure mainly comprises wet quick probe, wet quick probe is connected with the input end of music-integrating block, the output terminal of music-integrating block is connected with the input end of power amplifier, the output terminal of power amplifier is connected with loudspeaker, power supply is connected with power amplifier with music-integrating block respectively, and baby's one piss will be notified immediately, sometimes this music sound can startle the baby, urine can not once have been spread, wait to change behind the new diaper again can very fast urine wetly, increased the number of times of changing babies' napkin, not only can make the baby form the custom of interrupted piss, and often since the wet diaper of urine to contain the urine amount little, often do not report, be unfavorable for baby's physical and mental health.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved Urine-sounding instrument, after it can wait the baby to help a small child urinate by holding his legs apart all to have spread again sounding notify.

The technical solution of the utility model is achieved in that Urine-sounding instrument, it mainly comprises wet quick probe, wet quick probe is connected with the input end of music-integrating block, the output terminal of music-integrating block is connected with the input end of power amplifier, the output terminal of power amplifier is connected with loudspeaker, power supply is connected with power amplifier with music-integrating block respectively, it is characterized in that: establish a delay circuit between wet quick probe and music-integrating block, power supply is connected with delay circuit.

The utility model is owing to establish a delay circuit between wet quick probe and music-integrating block, the signal lag number that this delay circuit can transmit the quick probe that wets minute, when the baby is pissed, can not notify immediately, the drawback that the music sound startles the baby when having avoided the baby to piss, the wet diaper of baby was in time changed, reduced the replacing number of times of diaper simultaneously again, very useful to baby's physical and mental health.

Embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises box body, be contained in the box body or the outer wet quick probe 1 of box body, wet quick probe is connected with the input end of music-integrating block, the output terminal of music-integrating block is connected with the input end of power amplifier, the output terminal of power amplifier is connected with loudspeaker L, power supply is connected with power amplifier with music-integrating block respectively, one end of resistance R 1 is connected with the base stage of triode T1, the other end of resistance R 1 is connected with wet quick probe, it is different from prior art and is: establish a delay circuit between wet quick probe and music-integrating block, power supply is connected with delay circuit, delay circuit is during enforcement, the emitter of transistor T 1 respectively with the emitter of transistor T 2, one end of capacitor C 1, the end of diode D, one end of power end of music-integrating block () and power supply is connected, the collector of transistor T 1 respectively with the base stage of transistor T 2, one end of resistance R 2 is connected, the collector of transistor T 2 is connected with the base stage of transistor T 3, the emitter of transistor T 3 is connected with input end with the other end of diode D and the power end (+) of music-integrating block respectively, the collector of transistor T 3 respectively with resistance R 2, resistance R 3, loudspeaker, the other end of power supply is connected, one end of resistance R 3 is connected with the other end of capacitor C 1, present embodiment connects a capacitor C 2 between the collector of the emitter of transistor T 1 and transistor T 3, between the other end of the collector of transistor T 3 and power supply, connect a switch, the effect of capacitor C 2 is interchange internal resistances of eliminating power supply E (battery), can prolong the serviceable life of battery, power amplifier is a transistor T 4, and the model of music-integrating block is KD-9300.

Principle of work of the present utility model is as follows: when diaper does not have urine wet, because the other end of resistance R 1 is connected with wet quick probe and is hanging shape, one end of resistance R 1 is connected with the base stage of transistor T 1, transistor T 1 ends, transistor T 2 conductings, the electric charge at capacitor C 1 two ends is opened circuit, and transistor T 3 ends, music-integrating block is not worked, and loudspeaker is not also worked; When diaper urinated wet after, because the electric conductivity of urine, wet quick probe is equivalent to the resistance of a number kilohm, thereby make the base stage of transistor T 1 obtain the bias current conducting, the collector output electronegative potential of transistor T 1, transistor T 2 ends, at this moment power supply provides resistance R 3 to capacitor C 1 charging, so the base stage of transistor T 3 still keeps low level and is in cut-off state, music-integrating block is not worked, and along with the prolongation of time, capacitor C 1 both end voltage constantly rises, when the base stage that rises to the starting voltage of light emitting diode D1 and transistor T 3 when voltage is opened the door the voltage sum, transistor T 3 changes conducting state into by cut-off state, and music-integrating block gets electric work, and loudspeaker promptly sends the sound of notifying, the while lumination of light emitting diode, people hear the news and can replace more changing babies' napkin of baby.
