Description

Technical fields:

[0001] This utility model relates to the field of bathroom equipment technology, specifically to a bathtub water supply system device. Background technology:

[0002] In the current bathroom equipment field, bathtub water supply systems typically use traditional manual valves or simple thermostats to mix hot and cold water. These systems have several shortcomings: First, temperature control relies on manual adjustment of the mixing valve, making it difficult to accurately achieve the user's preset temperature, and they are easily affected by fluctuations in municipal hot and cold water pressure, resulting in inconsistent water temperatures. Second, flow regulation lacks real-time monitoring, requiring users to repeatedly adjust the flow to obtain the appropriate water volume, leading to low ease of use. Third, traditional systems do not integrate water treatment functions, failing to effectively treat impurities and bacteria in the water, affecting the bathing experience and hygiene safety. Fourth, energy efficiency is insufficient; the heating device and thermostat system have poor coordination, easily resulting in wasted energy. Furthermore, existing systems are mostly decentralized components, complex to install and maintain, and lack intelligent interactive interfaces, failing to meet modern users' demands for a comfortable, convenient, and healthy bathing environment. Therefore, there is an urgent need for a bathtub water supply system with intelligent regulation, precise temperature control, water quality optimization, and energy efficiency to solve the problems of inconvenient operation, low control precision, and limited functionality inherent in traditional technologies. Therefore, this utility model proposes a bathtub water supply system device to solve the shortcomings and defects of the existing technology. Utility Model Content:

The main control valve 002 is an electromagnetic valve, and its on / off state and opening degree are adjusted by the electrical signal from the control module 008. The temperature sensor 003 and the flow sensor 004 are both installed on the inlet pipe 001, and are installed close to the inner wall of the pipe. They are used to collect the inlet water temperature and flow rate in real time. The data is transmitted to the control module 008.
