Description
Technical field
The present invention relates to heater technology, and in particular to a kind of built-in from water power-off thermostat.
Background technology
Thermostat in the market is disposal current contact mode, is made between 2 joints by the electric action of water
The use environment of the mode of logical light current current voltage, identification water or air.Because fish jar environment center tap gets rusty easily, or easily quilt
Dirt is covered and thermostat is failed.Weak current becomes forceful electric power and is likely to result in security incident under given conditions.
Also disclose that many thermostats heated to fish jar case in the prior art, but these thermostat generally existings
One defect is exactly：In galvanization, when thermostat departs from water environment to be entered into air ambient, in thermostat now
Temperature can ramp, untill casing rupture, when rupturing, the relic of housing is easy to be splashed on body,
Very big injury is caused to human body.
Therefore, how effectively to solve also to be capable of power themselves down after thermostat disengaging water environment is entered into air ambient
Problem, is current problem in urgent need to solve.
The content of the invention
According to the deficiencies in the prior art, there is provided a kind of stable performance, low cost is completely insulated, can depart from the ring of water
What is automatically powered off under border is built-in from water power-off thermostat.
