Description

Technical Field

[0001] The utility model relates to the technical field of square water storage barrels, in particular to a square water storage barrel with a ventilation function. Background Art

[0002] Square water storage barrels are usually made of plastic. They are widely used as a water storage container because of their low cost, large capacity, and square structure that makes them easy to store and place.

[0003] The existing square water storage barrel usually includes a plastic square barrel, and the water inlet / outlet of the barrel is screwed with a barrel cover. When filling, pouring or drinking water, the barrel cover can be screwed off, which is convenient to use.

[0004] In actual use, in order to adapt to the drinking habits of most people who drink hot water and for safe drinking, boiling water is often poured into the water storage barrel. However, since the barrel is made of plastic and has a thin wall, during the cooling process, according to the principle of thermal expansion and contraction, the air inside the barrel will shrink, forming a negative pressure environment. Under the action of atmospheric pressure, the barrel wall will shrink to varying degrees, that is, there will be a local dent, or even a local flattening phenomenon, which will cause the lid to be unable to be opened normally, thus affecting the normal use of the barrel.
