Water leakage device

The water leakage prevention device of the present invention is mainly applied to the water leakage prevention technology of the water inlet and the water outlet channel when the machine or equipment leaks.

If the machine or equipment leaks water, if it does not stop water or water in the first time, it will cause the machine or equipment to malfunction or be damaged. In serious cases, there will be a dangerous situation of water leakage or leakage.

Therefore, general machines or equipment, such as water dispensers or water purifiers, are equipped with automatic water shutoff devices when water leaks; traditionally used water shutoff devices, in order to avoid inability to operate during power outages, mostly use power-free expansion bodies. The high expansion ratio after the water is absorbed by the expansion body pushes the water stop component to block the water inlet.

However, the conventional water-cutting devices still have at least the following problems and shortcomings that need to be overcome in practical operation:

1. The conventional water shut-off device adopts a single valve chamber, that is, both the influent and the effluent are carried out in the same valve chamber, so there is a widespread problem of turbulent flow.

2. The conventional water-cutting device uses the high expansion ratio of the expansion body to absorb water, directly pushing the water-stopping component to block the influent. Therefore, after accumulating a certain amount of water leakage and water accumulation, the expansion body can expand enough to push the water stop. The blocker blocks the action of entering the water, and the reaction is slow and inaccurate.
