Description

Automatic water stop device

This creation is an automatic water-stopping device, especially an automatic water-stopping device that can automatically stop the water flow when the water level reaches a certain height during the process of filling a container with water.

In daily life, water resources have a wide range of applications. In addition to being used as drinking water, it can also be used for irrigation of crops, cleaning, or breeding.

When a user needs to use water, he usually places a hose connected to a water source into a container and opens the water source to fill the container with water. During the process of filling the container with water, since the volume of the container is greater than the flow rate of water flowing out of the water source, the user must watch the water filling inside the container and manually close the water source when the water inside the container reaches a certain water level.

However, the process of waiting for water to be filled is relatively long. If the user forgets or fails to pay attention to the filling of the container, it is easy to cause excessive water to overflow the container, thereby resulting in a waste of water resources.

The main purpose of this invention is to provide an automatic water-stopping device, hoping to improve the current process of filling water in a container, which requires manpower to watch over. If the user does not forget or pays no attention to the filling of the container, it is easy to cause excessive water to overflow the container, thereby deriving the problem of water resource waste.
