AI Technical Summary
Existing auxiliary opening devices for drain valves are complex in structure, expensive, and lack standardized design, making them incompatible with mainstream drain valve products on the market.
A simple auxiliary opening device was designed, which is installed through the overflow pipe of the drain valve. It includes an installation component, a pressing actuator, and a driving component. The pressing actuator is driven by a motor and a transmission structure to press or release the drain valve button. Combined with a control circuit board and a signal transmitting device, the drainage volume can be flexibly adjusted.
It achieves low-cost, highly adaptable assisted opening of drain valves, compatible with most drain valves on the market, and amplifies the output torque through the transmission structure to provide powerful driving force, ensuring the accuracy and reliability of system operation.
