Description

Fluid filling device

The invention relates to a fluid filling device.

According to, the water tank needs to be filled after the vehicle has been used for a period of time. In order to avoid residual air in the water tank, when the liquid in the water tank is about to fill up, the water tank mouth is generally connected to a pipeline, which is connected to an air extractor , In order to pump out the air in the water tank, then connect the pipe to one end of the air pump and remove it and place it in a bucket, so that the liquid in the bucket flows into the water tank to fill the water tank. However, the above operation process is too lengthy. During the process of pumping the pipeline between the air pump and the bucket, it is easy to cause the liquid to overflow from the end of the pipeline away from the water tank, resulting in a humid and messy working environment.
