Abstract
The utility model discloses a kind of bathroom flush toilet water level caution circuit, comprise conductive head A and conductive head B, described conductive head A is connected in series with resistance R, switch S and power supply E, described conductive head B is connected with triode VT1, be connected with described power supply E after the emitter stage connecting luminous diode LED of described triode VT1, the base stage of the colelctor electrode connecting triode VT2 of described triode VT1, electric capacity C is provided with between the colelctor electrode of described triode VT2 and the base stage of described triode VT1, be connected with described power supply E after the colelctor electrode series connection loudspeaker BL of described triode VT2, the emitter stage of described triode VT2 is connected in parallel to resistance R and switch S.The utility model structure is simple, reasonable in design, can report to the police to the water level that transfinites, and prevents from causing because jettison gear is malfunctioning water level to transfinite the problem of overflowing, easy to use.
Description
Technical field
The utility model relates to a kind of warning circuit, is specifically related to a kind of bathroom flush toilet water level caution circuit.
Background technology
Often need in daily life to carry out early warning operation to some water levels, such as cistern water level, industrial production water level or reservoir level etc., these water-level alarm functions are of crucial importance.The water level of the flush toilet in such as bathroom, rest room is especially important, people may be had in domestic processes to nurse situation not bad, if in the bathroom in public place, once there is the situation of spilling water in flush toilet, often unmanned discovery, result in the water resource that waste is a large amount of, also make troubles to the cleaning in later stage.Flush toilet with water level early warning of the prior art generally generally adopts single-chip microcomputer integrated circuit to control, and cost is high, and later maintenance cost is also higher, uses inconvenience, is not suitable for extensive popularization.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provide a kind of structure simple, be successful low, control bathroom sensitive, that maintenance cost is low and easy to use flush toilet water level caution circuit.
Technical scheme: a kind of bathroom described in the utility model flush toilet water level caution circuit, comprise conductive head A and conductive head B, described conductive head A is connected in series with resistance R, switch S and power supply E, described conductive head B is connected with triode VT1, be connected with described power supply E after the emitter stage connecting luminous diode LED of described triode VT1, the base stage of the colelctor electrode connecting triode VT2 of described triode VT1, electric capacity C is provided with between the colelctor electrode of described triode VT2 and the base stage of described triode VT1, be connected with described power supply E after the colelctor electrode series connection loudspeaker BL of described triode VT2, the emitter stage of described triode VT2 is connected in parallel to resistance R and switch S.
As optimization, described conductive head A and conductive head B is located at different water levels respectively, and one of them conductive head is located at early warning water level.
As optimization, the amount of capacity ratio of described triode VT1 and described triode VT2 is 2:1.
As optimization, the size of described resistance R is adjustable resistor structure.
As optimization, the size of described power supply E is 6V.
Beneficial effect: the utility model structure is simple, reasonable in design, can report to the police to the water level that transfinites, prevents from causing because jettison gear is malfunctioning water level to transfinite the problem of overflowing, easy to use.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
A kind of bathroom flush toilet water level caution circuit as shown in Figure 1, comprise conductive head A and conductive head B, conductive head A is connected in series with resistance R, switch S and power supply E, conductive head B is connected with triode VT1, be connected with described power supply E after the emitter stage connecting luminous diode LED of triode VT1, the base stage of the colelctor electrode connecting triode VT2 of triode VT1, electric capacity C is provided with between the colelctor electrode of triode VT2 and the base stage of triode VT1, be connected with described power supply E after the colelctor electrode series connection loudspeaker BL of triode VT2, the emitter stage of triode VT2 is connected in parallel to resistance R and switch S.
As the further optimization of technique scheme, the conductive head A in the utility model and conductive head B is located at different water levels respectively, and one of them conductive head is located at early warning water level, during work, close switch S, when water level reaches early warning water level, two contact are reported to the police.The amount of capacity ratio of described triode VT1 and described triode VT2 is 2:1, the size of described resistance R is adjustable resistor structure, effectively the water level signal that conductive head A and conductive head B detects can be carried out amplification in real time, accurately to export, and export through loudspeaker BL warning.The size of described power supply E is 6V dc source.
The utility model structure is simple, reasonable in design, can report to the police to the water level that transfinites, and prevents from causing because jettison gear is malfunctioning water level to transfinite the problem of overflowing, easy to use.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
