Abstract
The utility model relates to an alarm for a child suffering coldness at night, which mainly solves the problem of alarm for the child who suffers the coldness after wetting a bed and kicking a quilt. The back part of the utility model is provided with an alarm for bedwetting, and the alarm for bedwetting is mainly composed of an amplifier, an oscillator, and a loudspeaker. The front of the utility model is also provided with child the two temperature measuring circuits, and the alarm for a child suffering coldness at night after the child kicks the quilt is composed of the two temperature measuring circuits and the alarm for bedwetting on the back. When the utility model is used, a bedwetting sensor is arranged under a diaper, and after the child wets the bed, the circuits are automatically switched on to enhance the alarm. Temperature sensors are tied on the front chest of the child and the back of the child, and after the child who kicks the quilt suffers the coldness, the thermosensitive resistance of the temperature sensors rises, and the circuits are switched on to enhance the alarm.
Description
The utility model relates to a kind of electronic alarm device, particularly a kind of children's catching cold alarm at night.
Children wet the bed and pedal out quilt and very easily suffer from cold illly night, have also brought many troubles to the head of a family.The report that children's urine-wet alarm device was once arranged before this, it mainly is made up of amplifier, oscillator, loudspeaker and a urine wet sensor.It can send chimes of doom after children wet the bed, and reminded the head of a family in time to change by the wet diaper of urine.But children sleep and easily pedal out quilt and suffer from cold its powerless warning.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of children's catching cold alarm at night is provided, and no matter is that children wet the bed or pedaling out quilt all can report to the police.
The purpose of this utility model is achieved in that there is a shell outside of the present utility model, and shell is provided with switch and socket.Be provided with circuit board in the shell, it is provided with alarm circuit.The rear portion of this warning circuit is the wet alarm circuit of Children's Urine, and oscillator that the amplifier that it is made of three utmost point BG7, triode BG8 constitute and Resistor-Capacitor Unit, urine wet sensor are formed.Unique distinction of the present utility model is: the front at the wet alarm circuit of Children's Urine also is provided with temperature measurement circuit, and amplifier, oscillator and loudspeaker in it and the urine-wet alarm device are formed children jointly and pedaled by catching cold alarm night.
Above-mentioned said temperature measurement circuit is two, and each temperature measurement circuit is made up of three triodes, thermistor, adjustable resistance and biasing resistance.Two thermistor (Rt
1And Rt
2) all be arranged on the temperature sensor, corresponding with children's shirtfront and the back position of suffering from cold respectively.Two temperature measurement circuits all with urine-wet alarm device in amplifier join and then connection oscillator and loudspeaker.
The utility model is simple in structure, and is easy to use, and the children that can report to the police wet the bed, and the children that can report to the police again suffer from cold shirtfront or back because of pedaling out quilt in bed.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is topology layout figure of the present utility model.1,2 is the jack of temperature sensor among the figure, and 3 is circuit board, and 4 is shell, 5 jacks for the wet sensing of urine, and 6 is switch, and 7 is battery folder, and 8 is battery, and 9 is loudspeaker.
Fig. 3 is the structural representation (tying up to children's shirtfront and back) of temperature sensor in the utility model.Among the figure, 10 is nylon buckles, and 11 is thermistor, and 12 and 13 is plug, and 14 is thermistor, and 15 is cloth.
Fig. 4 is the structural representation (being placed on below the diaper) of urine wet sensor in the utility model.Among the figure, 16 is Polypropylence Sheet, and 17 and 18 is bare copper wire, and 19 is plug.
Each structure shown in the drawings and circuit are exactly embodiment of the present utility model.When only using urine-wet alarm device, urine wet sensor plug 19 can be inserted jacks 5, urine wet sensor is placed on below the Children's diaper, be urinated when diaper and be equivalent to the resistance that sensor inserts a 90K Ω after wet, so the base stage of triode BG7 and power connection, loudspeaker can be reported to the police.When using catching cold alarm, the plug 12 and 13 of temperature sensor can be inserted jack 1 and 2 respectively, temperature sensor is tied up to children's chest, two thermistor (Rt on it
1And Rt
2) place shirtfront and back respectively, when children are pedaled out by the period of the day from 11 p.m. to 1 a.m, its temperature descends, and thermosensitive resistance raises and makes the emitter voltage of BG3 or BG6 be higher than base voltage, so BG7 has enough current lead-through, makes the loudspeaker sounding alarm.
