Abstract

The utility model discloses a baby-protection device, belonging to the technical field human living necessaries. The utility model comprises a temperature probe and a humidity probe. The two probes are connected with the signal input terminal of a transistor switching circuit by conducting wires, the output terminal of the transistor switching circuit is connected with the input terminal of a music and power amplification circuit, and the output terminal of the power amplification circuit is connected with a buzzer. The utility model can send out a warning when the humidity and the temperature change during a baby's sleep; the warning can remind other people to change a diaper or cover a quilt for the baby in time, in order to prevent the baby from catching cold.

Description

Baby protector

The utility model belongs to the essential technical field of human lives, further relates to a kind of baby protector of the infant's of being used for life.

The infant urinates wet bed clothes sometimes in the life in sleep, can suffer from cold as untimely more changing babies' napkin.For this reason, the someone has invented diaper, attempt to solve the wet problem of urine from diaper material, but urine still lodges in the quilt, and moisture is very big, and still be clammy winter, and child is suffered from cold.Kicking off quilt in the sleep also suffers from cold easily.

The purpose of this utility model is to provide a kind of baby protector that gives the alarm when humidity and temperature change in infantal sleeping.

The utility model comprises detector and signal processing circuit, detector is temp probe and moisture probe, two probes link to each other with the signal input part of transistor switching circuit through cable, the output termination music of on-off circuit and the input end of power amplifier, the output termination hummer of power amplifier.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a block scheme of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.

The utility model moisture probe 1 is that major axis is 15～25mm, and minor axis is the oval two-sided copper-plated epoxy resin board of 8～15mm, thickness of slab 1～1.5mm.Moisture probe links to each other with the moisture signal input end of on-off circuit 3 through soft two-conductor line, ∮ 2.5mm plug, socket.The thermistor that temp probe 2 is links to each other with the moisture signal input end of on-off circuit through soft two-conductor line, ∮ 2.5mm plug, socket.

T1 is the positive-negative-positive switching tube in the electrical schematic diagram, type selecting 9012, and its effect is to trigger musical film YYP, its base stage is through resistance R ₂Link to each other with temp probe 2, when moisture probe 1 conducting, R ₂On have electric current, T1 sends music signal thereby start musical film because of there being base current open-minded, T2 is a NPN type switching tube, type selecting is 9013, T2 and VD1 (IN4007) form temperature observation circuit jointly.When temp probe 2 signals reach set-point, the T2 conducting, and pass through R ₂Provide base current to T1, musical film is triggered and the outputting music signal.C ₁, C ₂, C ₃, R ₁The resistance-capacitance network of forming plays the anti-interference effect of filtering, and circuit can be worked reliably, and this network is connected across the trigger end of power supply and YYP.RK1 is power switch and volume control potentiometer, is serially connected in the power circuit.L ₁Being power light, is common light emitting diode.R ₄Be the pilot lamp current-limiting resistance.L ₁With R ₄Be connected on after the series connection between the power lead and ground wire of circuit.SPK is a hummer, is connected on the output terminal of music and power amplifier.SW is the moisture probe jack.WD is the temp probe jack.

Musical film YYP in music and the effect circuit 4 selects for use general any music all right, but does not select terrified music for use, has NPN triode 9013 rate of doing works to amplify in the circuit.At last music is exported through the hummer sounding.

The utlity model has urine wet inform and pedal be apprised of, have the function of infant music education concurrently.To in the infantal sleeping or urine at ordinary times wet and pedal by, can in time send music and remind tame long process, avoided child to be immersed in for a long time suffering from cold in the wet cloth and pedaled by after suffer from cold.As prompting, can regulate by its volume with music for present technique, and family and child are not had bad stimulation and scaring.Present technique can offer the music that child is acceptant and like in addition, and through repeat playing, child is easy to remember these music, and when music was sounded, child can have a sense of security and cordial feeling.Intelligence development to child also has a kind of optimal stimulation.Help child's intelligence development.And avoided the past to listen fidgety that the complicated music that do not conform to the age causes to child, uneasiness, the morbid night crying of babies etc. are the desirable articles for use of infant care.
