A built-in water separation power failure thermostat, temperature control method and water separation power failure sensor

Abstract

The invention discloses an internal-mounted water-leaving-power-off thermostat. The internal-mounted water-leaving-power-off thermostat comprises a quartz tube. A heating frame is arranged in the quartz tube, and comprises a cruciform mica frame and four heating wires, the four heating wires abut against right-angle seams of the cruciform mica frame respectively, two free ends of the four heating wires are reserved, the rest ends of the four heating wires are sequentially connected in series, any one of the two free ends is sequentially connected with a temperature control switch and a fuse to be connected to a controller through a wire, and the other one of the two free ends is connected to the controller through a wire; a water-leaving-power-off sensor is located in the quartz tube, abuts against the four heating wires, and is connected to the controller through a wire; a constant temperature sensor is connected to the controller through a wire. According to the internal-mounted water-leaving-power-off thermostat, power of the thermostat can be automatically cut under the condition of leaving water through the independent-research-and-development water-leaving-power-off sensor, the danger that under the condition of leaving water, as the temperature rapidly rises, the thermostat is burst is avoided, and the personal safety of a user is guaranteed.

Description

technical field [0001] The invention relates to heating device technology, in particular to a built-in water-disengaging power-off thermostat. Background technique [0002] At present, the thermostats on the market are all in the way of dealing with current contacts. Through the conduction of water, a weak voltage and current is passed between the two joints to identify the use environment of water or air. The thermostat fails due to the fact that the joints in the fish tank environment are prone to rust, or are easily covered with dirt. Under certain conditions, a weak current becomes a strong current, which may cause a safety accident. [0003] Also disclosed in the prior art are many thermostats for heating fish tanks, but these thermostats generally have a defect: in the process of power-on, when the thermostat breaks away from the water environment and enters the air environment, the thermostat at this time The temperature in the tank will rise in a straight line unti...

Thermostat failure due to joints that are prone to rust in fish tank environments, or become easily covered with dirt

Under certain conditions, a weak current becomes a strong current, which may cause a safety accident

[0003] Many thermostats for heating fish tanks are also disclosed in the prior art, but there is a common defect in these thermostats: in the power-on process, when the thermostat breaks away from the water environment and enters the air environment, the thermostat at this time The temperature in the tank will rise in a straight line until the shell ruptures. When a rupture occurs, the fragments of the shell will easily splash on the body, causing great harm to the human body.
