AI Technical Summary
The existing electromagnetic control method of two-position three-way valves generates significant noise during opening and closing, resulting in a poor user experience.
It adopts an electric motor drive, combined with a reciprocating module and an optimized exhaust structure, including incomplete gears and a muffler, to reduce noise generation.
It achieves a silent effect, reduces noise under electromagnetic control, and also reduces heat and useless power consumption, thus improving energy efficiency.
