Abstract
An electrical apparatus with an alarm includes an electrical device and an alarm system, the electrical device and the alarm system being both connected to an external power supply. The alarm system includes a wireless communication circuit and a control module. The control module is connected between the external power supply and the wireless communication circuit. The control module controls the wireless communication circuit to send an alarm notification when the electrical device is disconnected from the external power supply.
Claims20
An electrical apparatus with an alarm system, comprising:
- a power input terminal to receive an operation voltage for operation of the electrical apparatus;
- and
- an alarm system connected to the power input terminal to receive the operation voltage, the alarm system comprising:
- a wireless communication circuit;
- and
- a control module connected between the power input terminal and the wireless communication circuit, the control module comprising a voltage dividing resistor, a bias resistor, a battery and a transistor structured and arranged such that when an input power is provided to the power input terminal, the power input terminal provides the operation voltage to the transistor through the voltage dividing resistor and the bias resistor, to turn off the transistor, wherein the wireless communication circuit is an off-working state when no input power is provided to the power input terminal, and wherein the transistor turns on and the battery provides power to the wireless communication circuit such that the wireless communication circuit is in a working state to send an alarm notification.
