1. If bottled water is used, it is estimated that it is caused by air leakage in the bucket. The air leakage point is between the barrel mouth and the bottle cap. All bottled water is refilled. During the filling process, the barrel mouth will be worn to a certain extent. It will affect the sealing degree between the bottle cap and the barrel mouth. So I suggest you change a bucket of water.

2. If it is not a bucket, only the smart seat can be replaced. The air inlet you mentioned is a mesh at the top of the smart seat. Air first enters the water separator from the mesh, and then enters the bucket from the intelligent column. The water in the bucket exchanges places with the air, and then flows into the drinking machine.

That small round hole is vented. If the bladder is not heated and vented, it will burst. If you don't boil water and leak, just change the heating thermostat. If the water is not boiled and leaks, the one-way valve at the bottom of the water filter is broken. Just change it.

It's estimated that the float is broken. Just change it.
