Description
Affiliated technical field
The utility model relates to a kind of water and opens informer, and it can in time point out people's water to open, and prevents that boiling water from overflowing.
Background technology
People when cooking food since sometimes the time longer, people do some other things through regular meeting, and at this moment tend to forget and also cooking food, thereby cause boiling water to overflow, in addition pot in water dryout, food burns, What is more causes fire.Open suggestion device so be necessary very much the water of developing a kind of inexpensive practicality, in time point out people's water to boil, with unburned excessive.
Summary of the invention
Open suggestion device for the water of developing a kind of inexpensive practicality, in time point out people's water to boil, the utility model provides a kind of convenient and practical, simple in structure, cheap water to open informer, can be widely used in when family is daily to cook food to use.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises that battery, moisture sensor extension rod, water opens the water of informer and drive detection and power switch circuit, sound circuit, sounding and drive circuit; The water that battery, water are opened informer opens detection and power switch circuit, sound circuit, sounding and drive circuit are linked in sequence; The water that water is opened informer is opened and is surveyed and power switch circuit comprises moisture sensor, moisture sensor extension rod, NPN triode T1, a PNP triode T2, a resistance R 1; The moisture sensor extension rod is two hard wires, anode connects the emitter stage of PNP triode T2, the base stage of PNP triode T2 connects the colelctor electrode of NPN triode T1 by a resistance R 1, the emitter stage of NPN triode T1 connects GND, the base stage of NPN triode T1 meets in one of two hard wire of moisture sensor extension rod, this another root connects anode, the other end serial connection moisture sensor of two hard wires of moisture sensor extension rod, the colelctor electrode of PNP triode T2 meets the VCC of sound circuit and sounding and drive circuit, and the GND of sound circuit and sounding and drive circuit connects the negative pole of battery; The use that water is opened informer is such: when cooking food, the moisture sensor probe of water being opened informer is placed on the pot cover limit, a large amount of steam evaporations when opening, water are arranged, moisture sensor can detect, NPN triode T1 conducting, make PNP triode T2 conducting simultaneously, power switch circuit is opened, sound circuit is in time handled by sounding and drive circuit sounding prompting people.
The beneficial effects of the utility model are, and are simple in structure, practicality, and effect is obvious.
Description of drawings
Below in conjunction with accompanying drawing, implementation procedure of the present utility model is further specified.
Fig. 1 is a circuit diagram of the present utility model
