Abstract

The utility model relates to a baby urine wet alarm, which comprises an alarm with a musical box type, two-core leads which are provided with plugs, and a urine wet detector. The utility model is characterized in that the urine wet detector is composed of a nontoxic plastic thin piece and two piece-typed metal electrodes. The two piece-typed metal electrodes are embedded and fixed on the nontoxic plastic thin piece; one end of each of the two-core lead which is provided with the plug is sealed and fixed in the nontoxic plastic thin piece in watertightness way, and the end heads of the two leads are respectively connected with the two piece-typed metal electrodes; the plugs of the leads are inserted into the inserting opening of the alarm with a musical box type. The utility model can be used for alarming in time when babies urinate to cause diapers to be wet to remind adults to replace the diapers in time.

Description

The baby's urinating alarm device

This utility model relates to a kind of alarm, particularly relate to a kind of baby of prompting little alarm.

The baby large and smallly just can not arbitrarily be trickled in order to make, the bedding of making dirty, normally at baby buttocks diaper is set, and reuse kicking strap bundle is entangled on one's body the baby.But there are a lot of shortcomings in this method, as when baby's defecation, diaper is just soaked, because the baby does not know the notice adult, feces on the wet diaper or urine water is etch infant skin for a long time just, and it is red that infant skin is soaked, even cause dermatosis, this not only makes the baby very painful, and influences the baby and cosily grow up healthy and sound.

The purpose of this utility model is to provide a kind of baby's urinating alarm device at the problems referred to above, and when baby's urine or stool, diaper one is wet, just report to the police at once, and the prompting adult, the baby has urinated or is big.

The purpose of this utility model realizes by following technical proposals, that is:

The baby's urinating alarm device comprises the two core leads of urinating wet detector, alarm and band plug.The wet detector of urine is made up of soft non-toxic plastic thin slice and two chip metal electrodes.2 chip metal electrode edges are solid on soft non-toxic plastic thin slice.The no plug one end watertightness of two core flexible cords is enclosed in the software non-toxic plastic, and the termination of its two leads is connected with two chip metal electrodes respectively, and the other end of two core flexible cords is plugged on the alarm by plug.

Alarm can be a music box.On music box, also be provided with the wet display lamp of urine.The electronic circuit of music box is by audion BG, resistance R, light emitting diode D, on and off switch K, battery E, music module IC, resistance R ₁Q connects and composes with loudspeaker.

Also can set up a diaper band, have a hole, two core flexible cords to stretch out in the hole on the diaper band, the wet detector of urine lies on the diaper band.

To urinate wet strap during use and lie on the diaper, will urinate wet detector and the diaper bundle fixes on the suitable location of baby's health with kicking strap, the energized K switch, light emitting diode D is bright, represents the power supply on.When the baby does not have urine or stool, diaper is done, because plastics are insulators, so be to be in off state between 2 chip metal electrodes on the non-toxic plastic thin slice of the wet detector of urine, audion BG in the electronic circuit of music box is in cut-off state, does not therefore have music and reports to the police.When baby's urine or stool, it is wet that diaper becomes, resistance decreasing between 2 above-mentioned chip metal electrodes (water resistance is widely less than plastics resistance), audion BG conducting, make music module IC work, sing the song of one section setting, the prompting adult by loudspeaker, the baby has urinated or is big, needs timely changing babies' napkin.

This utility model is simple in structure, and is easy to use, can guarantee that the baby is not urinated the hardship of wet etch skin, the stable sleep of energy, comfortable blossom out.

Fig. 1 is the structural representation of a kind of embodiment of the present utility model, and Fig. 2 is a kind of circuit theory diagrams of music box.The utility model is described in further detail below in conjunction with accompanying drawing.

The baby's urinating alarm device comprises the two core leads 3 of urinating wet detector 1 and alarm 2, being with plug.The wet detector 1 of urine is made up of non-toxic plastic thin slice 4, chip metal electrode 5 and chip metal electrode 6.

Chip metal electrode

5 and 6 is inlayed solid on non-toxic plastic thin slice 4 respectively.The no plug one end watertightness sealing of two core leads 3 of band plug is in the non-toxic plastic thin slice, and the termination of two leads is separately fixed on chip metal electrode 5 and 6.The other end of two core leads 3 of band plug is plugged on by plug on the interface of alarm 2, is connected with the internal circuit of alarm 2.Alarm 2 is a music box.The electronic circuit of this music box is by audion BG, resistance R and R ₁, light emitting diode D, on and off switch K, battery E, music module IC and loudspeaker Q.On and off switch K and battery E series connection back are in parallel with the series circuit of resistance R and light emitting diode D, one end of this parallel circuit is connected with 4 feet of loudspeaker Q and music module IC, the other end is connected with chip metal electrode 5 by lead, be connected with the colelctor electrode of audion BG simultaneously, the base stage of audion BG is connected with chip metal electrode 6, the emitter stage of audion BG is connected with 1 foot of music module IC, and passes through resistance R ₁Be connected with its 2 foot.

Claims

1, baby's urinating alarm device, the two core leads (3) and the wet detector (1) of urine that comprise alarm (2), band plug, the plug of two core leads (3) of band plug, insert in the interface of alarm (2), it is characterized in that described urine wet detector (1), form by non-toxic plastic thin slice (4), chip metal electrode (5) and (6), chip metal electrode (5) and (6) are inlayed respectively and are fixed on the non-toxic plastic thin slice (4); The no plug one end watertightness sealing of two core leads (3) of band plug is in non-toxic plastic thin slice (4), and the termination of its two leads is connected with (6) with chip metal electrode (5) respectively.
