Description

A water dispenser using bagged water

Technical Field

The invention belongs to the technical field of water dispensers, and in particular relates to a water dispenser using bagged water.

Background technique

When drinking water from a traditional water dispenser that uses a large barrel of water, air will enter the dispenser because the barreled water is inverted. Bacteria and microorganisms in the outside air will contaminate the large barrel of water and attach to the inside of the dispenser. Since the water in the water tank cannot be discharged and the heating tube exists, this becomes a breeding ground for bacteria. In addition, air will enter the large barrel of water during the water discharge process, causing secondary pollution; repeated use of the barrels is prone to cross contamination.

When taking water from a water dispenser that uses a large barrel of water, air must enter the water bucket so that the water in the bucket can flow smoothly into the water dispenser and out of the water dispenser faucet. In order to allow outside air to enter the water bucket, all ordinary barrel water dispensers are equipped with an unsealed water tank under the smart seat. As a place for the exchange of water and air, and a place for the discharge of steam generated when the heating water tank is heated, outside air enters the water bucket through this water tank, and the water in the water bucket is also diverted to the cold water faucet and the heating water tank through this water tank. Since there are a large number of harmful substances such as bacteria and viruses in the air, when the air enters the water bucket, these harmful substances are also brought into the water bucket, so that the originally clean and hygienic drinking water is polluted again.
