Abstract
Background: With the rapid development of global economy, the utilization of water resources has become a prominent issue. Water shortage is a serious challenge, thus, water conservation is an important measure to help alleviate a water resources shortage and promote economic and social sustainable development. Currently, the inefficient use of water resource is very common in metropolitan and rural areas. Therefore, the efficient use of water in sustainable development has become an important issue in recent years. Previous research documents that the water tap switch speed affects water-saving efforts in the civil and industrial industries.
Objective: The purpose of this study is to develop a new type of water-saving control device for a water tap switch that provides an effective and efficient method of water-saving.
Methods: In this study, the patent is based on the Archimedes principle, lever principle and liquid pressure relating to water-saving and environmental protection machinery.
Results: A control device is utilized for water-saving application in an unmanned operation maintaining an established water level without utilizing any resources.
Conclusion: The control device of a water tap switch improves the efficiency of water use. Advantages include a simple structure, convenient use, ease of maintenance, and reliable performance. Recent patents of water-saving control devices promote water-saving technology that leads to additional watersaving control devices for water tap switch.
Keywords: Control device, lever principle, liquid pressure, sucking disc, tap switch, water-saving.
