Title:
WATER FLOW RATE AUTOMATIC CONTROL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/143492
Kind Code:
A1
Abstract:
A water flow rate automatic control module, relating to the field of constant-temperature shower parts. The water flow rate automatic control module comprises: a base (1), a valve body (2), a heat-sensitive component (20), and a diaphragm (3); a temperature sensing unit (10) senses the temperature of passing cold water in real time; when the cold water temperature is low, a mixed water flow rate is slowed and more hot water is supplied to a constant-temperature valve core assembly (17) for mixing; when the cold water temperature is high, a mixed water flow rate is increased and more cold water is supplied to the constant-temperature valve core assembly for mixing. Therefore, the mixed water temperature range of the constant-temperature valve core assembly can be ensured, and the problem of a temperature adjustment failure or temperature out-of-tolerance generated by matching a constant-temperature shower with a gas water heater is solved.
