Abstract

The utility model discloses a badge type weather alarm for children, comprising a fixture, a badge-shaped shell, and a flexible chain connecting the fixture and the shell, and a circuit in the shell is formed by that one end of a switch is connected with a power supply and the other end is connected with a thermal bimetal probe; one end of the thermal bimetal probe connected with the switch and the other end connected with the power supply are connected with a thick-film circuit; the other end of the thick-film circuit is connected with a press electroacoustic device and a luminous tube. When the probe tests that temperature is lower than the preset temperature, the power supply is switched on and signals are sent out. The utility model has the advantages of novel design, accurate control and fast reaction speed, can send out signals within seconds when children kick off quilts, and is useful for parents.

Description

Badge formula children changes in temperature reminiscences

The utility model relates to prompting, warning device, particularly a kind of badge formula children changes in temperature reminiscences.

As everyone knows, the infant time has in sleep pedals the custom of playing quilt, this be because: (1), children are in the instinct of development growth phase, daytime the brain fever, evening, cerebral cortex still was in excitatory state when sleeping, can not suppress trick and touch, cause pedaling and play bed clothes.(2), body part is itched when children sleep, do not use hand and scratch where it itches, play quilt and reach antipruritic and can only pedal.(3), when the temperature in the quilt is higher, also can play quilt, pedaling therefore that to play be a kind of instinct action, also is a kind of spontaneous phenomenon.If the head of a family fails in time to observe, in time nursing will cause children to suffer from cold, flu, and fever, and make father and mother cause psychology and financial burden.For a long time, a lot of technological means under people's effort, occur and solved this problem.As: use microelectric technique, but this kind technical difficulty is big, the cost height, and use also more complicated, be difficult for being accepted by people.

The purpose of this utility model provides a kind of badge formula children changes in temperature reminiscences, and on one's body it was clipped in, when bed clothes are kicked very short time off, reminiscences will be sounded, and tells head of a family adult, thereby makes child be difficult for suffering from cold, flu.

The purpose of this utility model is achieved in that

Reminiscences comprises anchor clamps, the shell of a badge shapes, the soft chain of jockey and shell.Circuit in the shell is a termination power of switch, and termination thermo bimetal probe connects this end of switch and another termination thick film circuit of power supply at thermo bimetal's probe, at the other end of thick film circuit and connect piezo-electric acoustic generator and luminotron.

The utility model modern design, simple, reliable, precise control, reaction velocity is fast, in seconds will send acousto-optic as long as kick quilt off, reminding alarm, and cost is low, is easy to be accepted by people.

Further describe below in conjunction with accompanying drawing:

Fig. 1 is external form figure of the present utility model

Fig. 2 is the utility model circuit theory diagrams

Among the figure: 1-anchor clamps, 2-shell 3-soft chain 4-two thermometal probe 3-thick film circuit 6-power supply 7-luminotron 8-probe guards

With reference to accompanying drawing, it 4 is that detecting element and executive component are integrated that the thermo bimetal pops one's head in, and has replaced a large amount of microelectronic components with an element, set two critical temperatures, when probe records temperature and is lower than maximum temperature, open power supply 6, just can send sound and light signal, when probe records temperature and is higher than minimum temperature, will power cutoff, the whole working time was not more than for 2～3 seconds, entered holding state then, and holding state accounted for for 90% above time, therefore very power saving.

Shell 2, anchor clamps 1 are made of plastic, and the thickness of shell 2 is at 5～8mm, and reminiscences can be clipped in the following position of the above neck of belly.

Claims

1, a kind of badge formula children changes in temperature reminiscences is characterized in that it comprises; Anchor clamps (1), the shell of a badge shapes (2), the soft chain (3) of a jockey (1) and shell (2);

2, reminiscences according to claim 1, it is characterized in that the circuit in the described shell (2) is switch one termination power (6), one termination thermo bimetal pop one's head in (4), connect this end of switch and another termination thick film circuit (5) of power supply (6) at thermo bimetal probe (4), at the other end of thick film circuit (5) and connect piezo-electric acoustic generator HTD, luminotron (7).
