Description

A sterilizing water dispenser

technical field

The utility model relates to a water dispenser, in particular to a water dispenser with sterilization and disinfection functions, and belongs to the technical field of water treatment.

Background technique

With the improvement of the quality of human life, drinking water dispensers have become widely used drinking water supply facilities in homes, hotels, offices and public places. Since most drinking water dispensers use bottled water as the water source, the water storage buckets are generally placed on top of the drinking water dispensers. To ensure smooth water discharge from the water dispenser, an air inlet is provided on the smart seat of the water dispenser that matches the water storage tank. When the water dispenser nozzle switch is turned on, a negative pressure zone is formed in the top space of the water storage tank as the water flows out, and the air enters The air port enters the water storage barrel, so bacteria, viruses and dust carried in the air can cause pollution of drinking water and bring adverse effects on the health of drinkers.

In order to solve the above problems, the Chinese utility model patent document with the application number 201220370932.1 discloses an ozone disinfection water dispenser, which consists of a water dispenser shell and a bucket, with a water cavity on the top of the water dispenser and a water inlet valve in the middle of the water cavity , By installing ozone in the water dispenser, the air entering the water dispenser is sterilized, and the ozone is carried into the water dispenser through the air to disinfect the water, thus ensuring the safety of drinking water. However, in the technical solution of this patent, the working time of the ozone generator is controlled by the change of the water level in the water chamber. Since the working time of the ozone generator is short, the amount of ozone produced cannot meet the concentration requirements for disinfection of bottled water and it is to remove dust and impurities in the air by being arranged on the air filter on the water dispenser shell, which not only increases the manufacturing cost of the water dispenser, but also needs to regularly clean the air filter, which brings inconvenience to the user.
