In order to facilitate quick water filling, washing machines at this stage are generally provided with a water connecting pipe directly connected to the faucet. The water connecting pipe is generally provided with a clamping sleeve at one end connected to the faucet. However, if the clamping sleeve cannot fit tightly with the faucet due to looseness, aging or internal damage, water leakage will occur. Especially in some campuses and urban laundries where washing machines are frequently used, if the water leakage cannot be discovered in time, it will cause certain water resource and economic losses.

[0003] For this purpose, the prior art CN 218565157 U proposes a water leakage alarm device for a washing machine water pipe, which is provided with a device mainly composed of a controller, a solenoid valve, a water immersion sensor and other devices. The water immersion sensor determines whether the water pipe clamp sleeve is leaking and transmits the signal to the controller. The controller controls the on and off of the solenoid valve to interrupt the water supply of the washing machine. However, its main components need to be provided with an AC-DC converter to be powered by a socket, which is inconvenient to use and wastes energy. If the water flow in the washing machine water pipe can be reasonably utilized as the energy source of the entire device, no external power supply is required, green energy saving and more environmentally friendly, the above problems can be solved. Therefore, it is imperative to invent a washing machine water pipe leakage alarm device that does not require an external power supply. Summary of the invention
