Description
The small-sized water level alarm of the utility model multi-usage is used for cistern water level control warning device, and baby' diaper is done wet, and display room rains outward and reports to the police.It is more suitable particularly to control warning device for the domestic solar water heater.
Commercially available solar domestic water heater roughly has two kinds at present: a kind of is the plate water heater of Automatic Cycle, and another kind is the passive solarenergy water heater, and these two kinds of water heaters are not all had water level control warning device.During water, the user just will stop by water tank on the water tank of solar water heater, treat that water overflows from overflow vent after, but valve-off just makes the people feel very inconvenience.Go up water in this way and have two big shortcomings at least: (1) is gone up water and must be waited for by water tank the user, loses time.(2) behind the full casing of water, flow out from overflow vent, the water waste is serious.
On bigger solar water heater, because of the last water time longer, people often use mechanical plastics water control warning device, but because of excessive temperature differentials in the solar water heater storage water tank, the plastics ball float is aging too fast, spheroid leaks serious, and reasons such as difficulty are slipped up frequently, installed in control, and are difficult for generally promoting and using.Machinery plastics ball float water control warning device is the buoyancy that utilizes water that ball float is produced, and when water level rose, ball float rose synchronously, and to the predetermined water level line, floating ball rod touch switch turn-on power makes a kind of device of alarm work.For safety connecting rod generally will stretch out outside the case, but can only being the interior water of water tank, the consequence of this practice heats up slowly, and heat energy " the outer race ", while plastics floating ball diameter is bigger, and ball float has accounted for the position and can not effectively utilize water tank in water tank.
The purpose of this utility model provides the small-sized water level alarm of a kind of multi-usage, adopt automatic control circuit and warning circuit to constitute alarm circuit, can report to the police to cistern water level control, particularly the control of solar water heater water level is reported to the police more suitable, baby' diaper be can also carry out in addition and wet demonstration, outdoor rainy warning done.
The small-sized water level alarm of multi-usage takes following scheme to realize: the multi-usage water level alarm is mainly by casing, warning selector switch, power switch, light emitting diode, alarm ring newspaper loudspeaker, connect water-level probe binding post, water-level probe, the alarm circuit, the electronic component that are installed in the casing constitute.The alarm circuit partly is made of automatic control circuit part, warning circuit.
