CN201017438Y - Alarm for baby wetting the bed - Google Patents

Abstract

A baby bed-wetting alarm device is provided, which comprises a cabinet, a circuit controller, a loudspeaker Y, batteries E1 and E2 inside the cabinet. Wherein, the cabinet top is arranged with an alarm lamp; on the front panel of the cabinet mount a power source switch and two junction terminals. The circuit controller is composed of an earth detector switch K, a music generation circuit chip U and a loudspeaker Y. One end, m, of the earth detector switch K is linked to the positive electrode on the battery E2; the other end, N, of the earth detector switch K is attached to Pin 2 on the music generation circuit chip U; Pin 3 on the chip U is connected with the negative electrode on the battery E1; the positive electrode on the battery E1 is connected through a switch K1 with the negative electrode on the battery E2; Pin 1 on the chip U is simultaneously linked to one end of an indication lamp L and one end of the loudspeaker Y; the other ends of the indication lamp L and the loudspeaker Y are simultaneously connected with Pin 2 on the chip U. The utility model has advantages of elegant speculation, simple fabrication, low material consumption, low cost, convenient utilization and being safe and reliable; therefore, the alarm device adapts to baby bringing-up in households.

Description

Baby's alarm of wetting the bed

Technical field

The utility model relates to a kind of alarm, concrete the is baby wets the bed alarm.

Background technology

The baby wets the bed the back under the situation that auntie or mother do not know, and is in moist state for a long time and is sunk into sleep, and this is totally unfavorable to baby's health.Be not used for specially finding that baby's very first time wets the bed but have as yet at present, the very first time is in time carried out the device of changing babies' napkin more or bed clothes to the baby with sound and light prompt mother or auntie.

Summary of the invention

The purpose of this utility model is in order to solve the timely discovery baby problem of device and the baby that the provides alarm of wetting the bed of wetting the bed not to be arranged as yet at present.

The technical scheme that adopts:

Baby's alarm of wetting the bed comprises casing and is contained in circuit controller, loudspeaker Y, battery E1, E2 in the casing; The last end face of described casing is placed with alarm lamp, and the front face of casing is provided with power switch and two connection terminals.

Described circuit controller, comprise detection of electrical leakage K switch, music generative circuit chip U, loudspeaker Y, one end m of detection of electrical leakage K switch connects the positive pole of battery E2, the other end n of detection of electrical leakage K switch connects 2 pin of music generative circuit chip U, 3 pin of music generative circuit chip U connect the negative pole of battery E1, and the positive pole of battery E1 connects the negative pole of battery E2 through K switch 1; 1 pin of music generative circuit chip U connects the end of pilot lamp L and loudspeaker Y simultaneously, and the other end of pilot lamp L and loudspeaker Y connects 2 pin of music generative circuit chip U simultaneously.

The utility model is skillfully constructed, and makes simply, and materials are few, and are with low cost, easy to use, safe and reliable, and the suitable baby of family fosters middle use.
