Abstract

The utility model relates to a warner for children kicking out quilts, which is composed of a shell, and a temperature measuring circuit, a signal amplifying circuit, a sound circuit, a direct current power supply, and a switch which are arranged in the shell, wherein, a thermistor in the temperature measuring circuit is the temperature measuring element. When the measured temperature is equal to or lower than the set warning temperature, the sound circuit is triggered to send out sound. The warner is attached to the children's clothes when the children sleep. When the children kick out the quilts, the temperature measuring circuit sends out signals; through the processing and amplifying by the signal amplifying circuit in the warner, a music integrated package and a buzzing piece in the sound circuit work. Thus people can be reminded to preserve heat for children and prevent the children from catching cold.

Description

Children's's quilt-kicking warner

The utility model provides a kind of children's's quilt-kicking warner, belongs to a kind of temperature drop warning device of catching a cold when preventing children sleeping.

Existing children are pedaled and are alerted device, complex structure, and sensitivity is low, triggers poor stability, pedals out the problem that quilt is suffered from cold and reported to the police when being difficult to effectively solve children sleeping.

The purpose of this utility model is to provide a kind of simple in structure, the sensitive children's rapidly of temperature-responsive quilt-kicking warner, when children pedal by after, it can make warning rapidly, is that children are incubated with the big people of timely prompting, efficiently solves the ubiquitous warning problem of being suffered from cold of pedaling in the child care.

The purpose of this utility model is achieved through the following technical solutions:

Children's's quilt-kicking warner, it is made up of shell and temperature measurement circuit, signal amplification circuit, acoustics circuit, direct supply E and the K switch be located in the shell, the output signal of temperature measurement circuit is touched the acoustics circuit sounding alarm after signal amplification circuit amplifies, described temperature measurement circuit is by positive and negative thermistor R ₂, R ₁The bleeder circuit and the triode BG that form ₁Form thermistor R ₂And R ₁And be connected between the both positive and negative polarity of direct supply E thermistor R ₂And R ₁Dividing point meet triode BG ₁Base stage, triode BG ₁Emitter connect the positive pole of direct supply E, triode BG ₁Collector connect signal amplification circuit; But have 2 quick resistance R of heat supply on the described shell ₂And R ₁The through hole that stretches out (7), the vocal hole more than 2 (2) and 1 groove (5) that handle (4) moves of stirring that can supply K switch.

Principle of work of the present utility model is: before children are sleeping, the utility model is attached on children's clothes, quilt is built, the K switch closure on the utility model, at this moment, because the temperature in the quilt is a little less than setting alarm temperature of the present utility model, acoustics circuit in the utility model will be triggered and sounding like this, after one song has been played, when the temperature in the quilt is higher than setting alarm temperature of the present utility model, the utility model will enter stand-by state immediately, and in other words, the acoustics circuit in the utility model is sounding no longer, when children are pedaled out quilt in sleep after, temperature potential in the quilt must reduce, when the temperature in the quilt is lower than setting alarm temperature of the present utility model, on the reminiscences just, negative thermistor R ₂And R ₁To the outer low temperature of quilt, their resistance all changes (wherein: R with sensitivity ₁Resistance raises, R ₂Resistance descends), thus make triode BG ₁The voltage-to-ground step-down of base stage, triode BG ₁By by becoming conducting and produce a small electric signal, this electric signal through signal amplification circuit handle amplify after, touch the acoustics circuit sounding alarm, can in time remind big people for children are incubated like this, prevent children's flu of catching a cold.

Because the utility model adopts two thermistor R in the temperature measurement circuit ₂And R ₁As temperature element, it is just comparatively sensitive to the thermometric reaction of variation of ambient temperature like this, when dut temperature is equal to or less than the setting alarm temperature, acoustics circuit will be triggered at once, send the sound, thereby reach the purpose that timely prompting adult correlates children, therefore the utlity model has temperature-responsive sensitivity advantage rapidly; Because the utility model is by shell and be located at miniature thermometric in the shell and report circuit and formed, described miniature thermometric is reported circuit and is only comprised temperature measurement circuit, signal amplification circuit, acoustics circuit, direct supply E and K switch, therefore the utlity model has advantage of simple structure.
