Abstract

The utility model provides a simple baby's urine alarm device with electronic music. The utility model is composed of a music IC with high triggering sensitivity, a piezoelectric buzzer, a button cell and two roots of urine wet sensing conducting wires; the long bared parts of the sensing conducting wires are sewed or be in plastic compression on a T-shaped and plastic diaper pad to form a pad type baby's urine alarm device; the short bared wires are respectively stuck or are through a hot pressing at the two top ends of a small plastic clip to form a clip type baby's urine alarm device. The utility model has the advantages of simple circuit, small volume, low power consumption, moderate rine sound, grace music, low cost, convenient operation, etc.

Description

Baby's urine signalling device

The utility model provides a kind of easy electronic music urine-wet alarm.

Baby's urine-wet alarm is to reduce mother's fatigue, prevent that infant skin from macerating wet rotten to the corn good tool, baby's urine-wet alarm of seeing in the market, all employing transistor circuit persons, all exist volume big, power consumption is big, shortcomings such as newspaper urine sound equipment dullness, adopt music IC and transistor combination person, the big or bigger deficiency that waits of power consumption of volume is still arranged.

The purpose of this utility model provides a kind of simple baby's urine-wet alarm, accomplish that circuit component is minimum, the power consumptive province, and volume is little, and cost is low, newspaper urine music grace, sound equipment is moderate, but also easy to use.

The purpose of this utility model is achieved in that the music IC that adopts high trigger sensitivity, connect piezoelectric buzzer at its output pin, at power pins two termination button cells, triggering pin two termination anti-interference capacitors and two wet transducer wires of urine, constitute the circuit unit of baby's urine-wet alarm thus, during use, the bare wire part of two transducer wires is close to baby' diaper, when baby' diaper urine is wet, resistance between the transducer wire is become greatly about 30K Ω by no key, music IC is triggered and plays music, break away from wet diaper until transducer wire, music stops, and has reached to inform that the adult is in time to baby's purpose of changing babies' napkin more, for easy to use, with the long bare wires part of two transducer wires and circuit unit is made or plastic compression moulds on the material pocket diaper pad at T, constitute cushion baby urine-wet alarm, two transducer wire tail end bare wires parts are pasted respectively or hot pressing on small plastic clip two tops, circuit unit is packed in the small-sized plastic-shell, constitutes folder formula baby urine-wet alarm.

Cushion baby urine-wet alarm is reported the function except that realizing that urine is wet, can prevent that also wet diaper from soaking into mattress, and folder formula baby urine-wet alarm is flexible and convenient to use, but double as musical toy also.

The utility model is described in further detail below in conjunction with the embodiment of accompanying drawing and two kinds of structures:

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the structural representation of cushion baby urine-wet alarm.

Fig. 3 is the structural representation of folder formula baby urine-wet alarm.

Among the figure: 1, circuit unit 2, transducer wire 3, pocket diaper pad 4, nylon adhesive are buckled A 5, nylon adhesive is buckled B 6, plastic clip 7, moulded shell

In Fig. 1, music IC adopts KD15 series, and these series of products have high trigger sensitivity, and it triggers the resistance of two terminations greater than 200K Ω, just can trigger and play music, and urine contact resistance event triggering surplus about 30K Ω is very big, can guarantee newspaper urine accurately, and two button cell E can select for use the battery folder structure of KD1001 product to fix, also can make by oneself, hummer, HTD adopt φ 27 bands to help the piezoelectricity singing piece of the operatic tunes, capacitor C to prevent that false triggering from selecting 0.1 μ F.

In cushion baby urine-wet alarm embodiment shown in Figure 2, two sensing bare conductors (2) are parallel at a distance of about 10mm, segmentation is made or the perpendicular position, road of the T shape of plastic compression on the pocket diaper pad (3) of plastics or other nonabsorbent materials, circuit unit (1) is made or plastic compression erects the road tail end T shape, nylon adhesive button A(4) make at the two ends of T shape lateral road nylon adhesive button B(5) make both sides at T shape tail end.During use, diaper is placed on the pocket diaper pad,, fix with the nylon adhesive button then on the baby carrier.

In the embodiment of folder formula baby urine-wet alarm shown in Figure 3, two transducer wires (2) can be selected 0.5 meter insert earphone lead for use, tail end is reserved the bare wire of about 10mm, respectively with its stickup or hot pressing two tops at small plastic clip (6), and note staggering, make clip not short circuit of two bare wires parts when physical slot, circuit unit (1) is loaded on to be moulded in the shell (7), during use clip is clipped to baby' diaper and easily urinates the wet end position and get final product.

The KD15 series IC that the utility model adopts, atomic at its electric current of stand-by state, be generally less than 0.2 μ A, so can remove power switch from, use the piezoelectric buzzer sounding, sound is moderate, can not alarm the baby, and the power consumptive province adopts button cell can satisfy the use of baby carrier diaper phase, and it is simple and easy small and exquisite that circuit unit is accomplished.

Claims

1, a kind of baby's urine-wet alarm, adopt the music IC of high trigger sensitivity, connect piezoelectric buzzer at its output pin, connect button cell in power pins, triggering pin two termination anti-interference capacitors and two wet transducer wires of urine, constitute the circuit unit of baby's urine-wet alarm thus, trigger end connect two transducer wires of high trigger sensitivity music IC and the circuit unit of being characterised in that of the present utility model is fixed on the T shape pocket diaper pad, constitutes cushion baby urine-wet alarm; The short bare wire of two transducer wire tail ends partly is separately fixed at small plastic clip two tops, and circuit unit is packed in the small-sized plastic-shell, constitutes folder formula baby urine-wet alarm.

2, baby's urine-wet alarm according to claim 1, the long bare wire partial parallel of two transducer wires that it is characterized in that cushion baby urine-wet alarm is at a distance of about the 10mm, segmentation is fixed on the position, perpendicular road on the T shape pocket diaper pad, and circuit unit is fixed on the tail end in the perpendicular road of T shape.
