1. Working Principle
Mechanical Structure Control:
It has a set of complex mechanical structures, such as springs, gears, slide rails, etc., which can gradually change the size of the water channel when operated, so as to achieve the slow opening of the water flow.
When the user turns on the faucet, the mechanical structure begins to gradually expand or move, gradually increasing the water channel, so that the water flows out at a slow and steady speed.
Through the built-in sensors and processors, the device can monitor the water flow in real time and adjust the opening speed of the water flow according to the preset parameters or user settings.
Water flow resistance design:
The opening speed of the water flow is slowed down by designing a specific water flow channel shape or increasing the water flow resistance.
For example, by setting multiple curved or narrow parts in the water flow channel, the resistance of the water flow is increased when passing through, thereby slowing down the opening speed of the water flow.

2. Application Effect
Water-saving effect: The slowly opened water flow can make it easier for users to control the amount of water flow and reduce unnecessary waste.
Pressure relief effect: For pipe systems that need to withstand high water pressure, the slowly opened water flow can effectively reduce the impact of the water flow and protect the pipes from damage.
User experience: The slowly opened water flow can bring a softer water experience and avoid the discomfort caused by sudden water flow impact to users.

3. Precautions
Regular maintenance: In order to ensure the normal operation of the faucet Spool, users need to maintain it regularly, such as cleaning internal impurities and checking the wear of the mechanical structure.
Correct use: When using, users need to operate the faucet correctly according to the instructions in the manual to avoid damage to the device due to excessive force or improper operation.
