By utilizing the principle that the temperature control switch can be automatically switched off or automatically switched on when reaching the set temperature, the socket or the power strip is cut off the load, and meanwhile, the sound and light alarm is realized. The control loop is added in a common power strip or a five-hole socket, the principle of the control loop is that the head end of the circuit is connected with commercial power, and is connected with a normally closed temperature control switch in series through switch control to be connected to the load side of the power strip or the socket, when the environmental temperature or the high temperature caused by overload, short circuit and the like of the load exceeds the set safe temperature, the temperature control switch is disconnected, the load power supply is cut off, the temperature is prevented from continuously rising, and therefore the occurrence of fire is avoided. Meanwhile, the head end of the normally closed temperature control switch is connected with a normally open temperature control switch in parallel, the other end of the normally open temperature control switch is connected with an audible and visual alarm, and the other end of the audible and visual alarm is connected with an N line.)

1. The invention comprises the following steps: the control circuit of the invention is added in the socket or the power strip, namely, the commercial power firstly passes through the switch and is connected with a normally closed temperature control switch in series, then the commercial power is connected to the load side, meanwhile, the head end of the normally closed temperature control switch is connected with a normally open temperature control switch in parallel, the other end of the normally open temperature control switch is connected with an audible and visual alarm in series, the other end of the audible and visual alarm is connected to the commercial power N line, when the load temperature or the environment temperature exceeds the set safety range, the normally closed temperature control switch is normally opened, the power supply on the load side is cut off, the normally open temperature control switch is normally closed, and the audible and visual alarm gives out.

Technical Field

The temperature monitoring device is suitable for various places needing to monitor the temperature of load electric equipment.

Background

The circuit on-off of the load side is controlled by using the characteristic that the temperature control switch is changed from normally open to normally closed or from normally closed to normally open at a proper temperature, so that the purpose of protecting the load side from burning equipment or causing fire due to ultrahigh temperature is achieved.

Disclosure of Invention

The control circuit of the invention is added in the socket or the power strip, namely, the commercial power firstly passes through the switch and is connected with a normally closed temperature control switch in series, then the commercial power is connected to the load side, meanwhile, the head end of the normally closed temperature control switch is connected with a normally open temperature control switch in parallel, the other end of the normally open temperature control switch is connected with an audible and visual alarm in series, the other end of the audible and visual alarm is connected to the commercial power N line, when the load temperature or the environment temperature exceeds the set safety range, the normally closed temperature control switch is normally opened, the power supply on the load side is cut off, the normally open temperature control switch is normally closed, and the audible and visual alarm gives out.
