[0002] Currently, to ensure users receive a target fluid with specific parameters, it is often necessary to mix two fluids with different parameters, such as the TDS value or temperature of the corresponding fluids. This technology can be specifically applied to water purifiers or water heaters. For example, existing Chinese patent CN201120360449.0 discloses a corresponding water purifier device, which uses two electromagnetic flow control valves configured in a mixing pipeline to mix influent with different parameters by adjusting the opening of these valves, thereby obtaining effluent with suitable water quality.

[0003] However, this method of providing fluid flow through electromagnetic flow control valves is not well applied in complex working conditions, especially due to its slow response speed and poor flow control accuracy. In particular, when there are real-time fluctuations in the incoming water parameters, these electromagnetic flow control valves cannot guarantee that the parameters of the output water will be stably controlled at the target value.
