Automatic test device for heating seat rings of toilet bowls

Abstract

The invention relates to an automatic test device for heating seat rings of toilet bowls. The automatic test device comprises a resistance detection circuit, a sensor detection circuit, a processor and a power circuit. The resistance detection circuit and the sensor detection circuit are independent from each other. External tested devices can be connected into input ends of the resistance detection circuit, output ends of the resistance detection circuit are connected into the processor, external tested sensing devices can be connected into input ends of the sensor detection circuit, and an output end of the sensor detection circuit is connected into the processor; whether the tested devices are normal or not can be judged by the processor according to input signals of the resistance detection circuit and signal input states of the sensor detection circuit; power output ends of the power circuit are electrically connected with power input ends of the resistance detection circuit, the sensor detection circuit and the processor. The automatic test device has the advantages that the heating seat rings of the toilet bowls can be quickly tested by the automatic test device, the test efficiency can be improved, the test complexity can be lowered, and the automatic test device is simple in structure and convenient to operate and is portable.

Description

technical field [0001] The invention relates to the detection field of a toilet heating seat, in particular to an automatic testing device for a toilet heating seat. Background technique [0002] In order to prevent the user from feeling uncomfortable when sitting on a cold toilet, generally a toilet seat with a heating function is provided by covering the edge of the toilet. The existing toilet heating seat generally includes a shell, a capacitive sensor arranged on the top plate of the shell and used to test whether a human body is sitting on the shell, a thermistor control circuit and an aluminum foil heater set in the shell, and a controller . The capacitance sensor, the thermistor control circuit and the aluminum foil heater are electrically connected to the controller respectively, and the controller controls the opening and closing of the thermistor control circuit and the aluminum foil heater according to the capacitance sensor, and the aluminum foil heater During ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing fault detection or maintenance detection of the toilet heating seat is generally tested separately by multiple testers, and the test operation and test circuit are relatively cumbersome and complicated.

Moreover, when testing the aluminum foil heater, it is necessary to heat the aluminum foil in the aluminum foil heater separately and complete the heating to determine whether it is normal; in this way, a 220V power supply is required to heat the aluminum foil alone, which poses a threat to the safety of the testers. , and the test time is long and the test efficiency is low
