[0002] A water meter is a device used to measure water flow. It is usually installed by water supply companies in residential or building facilities to monitor and record water flow.

[0003] With the rapid development of science and technology in modern society, water meters are generally smarter and more comprehensive in functions. They even have the functions of remote operation and recording, without the need for manual door-to-door meter reading. However, the existing water meters still have some shortcomings when in use. For example, some faucets will have problems with aging or loosening of seals after long-term use. At this time, the faucet will continue to drip because it cannot be tightened. However, in this phenomenon, due to the slow water flow, the metering structure in the water meter cannot react. Therefore, the lost water flow cannot be recorded, which will cause great economic losses and waste of water resources, which is not conducive to environmental protection. Summary of the invention

When the water level drops to the specified position, the water level buoy will drop, driving the trigger unit to contact the sensing module. The sensing module is connected to the control module through a wire, and the control module records. At the same time, the control module will operate the No. 2 electric cylinder to push The dynamic extrusion block descends. When the extrusion block is pressed down to the specified position, the water in the extrusion groove will be squeezed into the water level groove through the extrusion hole. At this time, the water level in the water level groove rises again, driving the water level buoy to rise. When the faucet continues to drip, the water level buoy will be reciprocated and recorded multiple times through the above operation, so the dripping flow of the faucet can be monitored. At the same time, when the water stored in the water storage space is consumed, the control module will no longer operate the No. 2 electric cylinder, so that the water pipe can be separated from the water inlet end of the water meter to avoid wasting water resources.
