Description

Technical Field

[0002] The pre-filter in the prior art includes: a machine head, a filter bottle connected to the machine head at the upper end, a drainage ball valve connected to the lower end of the filter bottle, a filter screen frame is arranged in the filter bottle, and a filter screen is sleeved on the outer wall of the filter screen frame. During use, water flows from the water inlet of the machine head into the gap between the filter bottle and the filter screen, flows into the center of the filter screen frame after being filtered by the filter screen, and then flows from the center of the filter screen frame to the water outlet of the machine head. The pre-filter has now penetrated into thousands of households and high-end hotels.

[0003] During the use of the pre-filter, the supporting pipe network often leaks due to accidents such as aging, leakage, rupture of the water pipes, or faucets not being closed or forgotten to be closed. On the one hand, it causes a waste of water resources and an increase in water charges. On the other hand, it can seriously harm buildings and cause house damage and property losses. Especially in densely populated residential areas, a leak may cause losses to multiple units in the vicinity and lower floors, causing inconvenience to residents' daily lives. In high-end hotels and other places, floods may occur due to burst water pipes, which may seriously damage the high-end facilities in the hotel. Such situations occur frequently in real life, so leakage monitoring and protection are very necessary. Early detection and early resolution can avoid the expansion of hidden dangers. Leakage monitoring and protection equipment has emerged. The utility model aims to provide a leakage monitoring mechanism for a pre-filter with a more optimized structure and easy industrialization.
