Abstract

The utility model relates to a bed-wetting alarm, which comprises a casing, a bottom plate, a loudspeaker, a light emitting diode, a music integrated circuit, a battery, a resistor, a sensor, etc. The independent 3V battery is used as a power supply, the sensor and the resistor compose a level control circuit, and the music integrated circuit, the loudspeaker and the light emitting diode compose an alarm. Thus, when getting a relative humidity, the sensor can make the loudspeaker and the light emitting diode send out an audible and visual alarm. The utility model which is an ideal babies' health product can timely remind people to replace diapers for a baby, prevent the baby from catching dermatoses, and have the advantages of simple circuit, convenience, practicality and cheap price.

Description

Bed-wetting alarm

This utility model relates to a kind of alarm, particularly a kind of urine-wet alarm device.

In the family, the baby generally will use diaper, and often behind the baby's urinating adult in time do not change, make the baby bring out dermatitis or other dermatosiss, cause adverse consequences.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and can in time reports to the police after a kind of baby's urinating is provided, and simple, cheap, the convenient and practical urine-wet alarm device of circuit.

The purpose of this utility model can reach by following measure: this utility model comprises housing, base plate, loudspeaker, light emitting diode, music integrated circuit, battery, it is characterized in that: also have resistance and pick off, pick off is connected to 1,2 feet of music integrated circuit, and connect 4 feet of music integrated circuit by resistance, loudspeaker, light emitting diode also connect the back and join with 1,4 feet of music integrated circuit, and the lead-out wire that is fixed with loudspeaker, light emitting diode, pick off on the face-piece of housing is drawn from the side of housing.

Fig. 1 is an electrical schematic diagram of the present utility model;

Fig. 2 is this utility model contour structures front view;

Fig. 3 is this utility model contour structures side view.

This utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, this utility model comprises compositions such as housing 1, base plate 2, loudspeaker 3, light emitting diode 4, music integrated circuit IC1, battery 5, resistance R, pick off 6.Loudspeaker 3 and light emitting diode 4 are housed on the face-piece of housing 1, and lead-out wire 7 is drawn in the housing 1 and is joined with pick off 6.

Because diaper directly contacts with the baby, for guaranteeing safety, adopts independent 3V battery powered; Pick off 6 can be sandwiched in the diaper when using, and forms level control circuit with resistance R, forms urine-wet alarm device with IC1, loudspeaker 3, light emitting diode 4.When diaper was dry, pick off 6 resistance were greater than 1M Ω; Under the steam effect, also more than 24K Ω, IC1's resistance is failure to actuate.When urine was wet, the resistance on pick off 6 was less than 24K Ω, and until approximate short circuit, at this moment, IC1 is triggered, and 1,4 foot outputting music signals make loudspeaker 3 sounding, and light emitting diode 4 is bright, sends sound and light alarm, and reminds people in time is a more changing babies' napkin of baby.When changing new diaper and drying the urine of pick off 6 when wet, sound and light alarm stops, and recovers original state.

The utility model has following advantage compared to existing technology:

1. when the wet sound of baby' diaper urine, can in time send sound and light alarm, the prompting people in time are more changing babies' napkin of baby, prevent that the baby from catching disease of skin.

2. circuit is simple, cheap, convenient and practical, is a kind of ideal baby health-care articles for use.

Claims

1, a kind of urine-wet alarm device, comprise housing 1, base plate 2, loudspeaker 3, light emitting diode 4, music integrated circuit IC1, battery 5, it is characterized in that: also have resistance R and pick off 6, pick off 6 is connected to 1,2 feet of IC1, and connecing 4 feet of IC1 by R, loudspeaker 3, light emitting diode 4 and 1,4 feet that meet back and IC1 join.

2, alarm according to claim 1 is characterized in that: be fixed with loudspeaker 3, light emitting diode 4 on the face-piece of housing 1, the lead-out wire 7 of pick off 6 is drawn from the side of housing 1.
