Double-layer drinking bucket to solve the secondary pollution

Bottled drinking water has entered the lives of millions of households. In daily use, drinking water is often used for a long time and deteriorated, resulting in odor. Recently, Yang Shuangqing, a sophomore at Tongji University's School of Economics and Management, invented a new type of double-layered drinking bucket that enables the drinking water in the drinking bucket to be “preserved” for a long period of time.

It is understood that the use of drinking water as an air filter during use is a major cause of water deterioration. Whenever the cold or hot water switch is pressed to release drinking water, bubbles can be seen tumbling in the bucket and a "click" sound can be heard. This is because the drinking water machine in the process of water discharge, the formation of negative pressure in the barrel, the air from the barrel into the bottom of the barrel, when drinking water actually acts as an air filter, air, dust, bacteria, microorganisms and other harmful substances Will be filtered in drinking water, water and gas fusion so bacteria multiply quickly, pollute the water quality. If someone in the office has a cold, a cold virus enters the air, and the air enters the drinking water tank to pollute the drinking water, people in the same office drink drinking water with cold viruses.

The new double-layer drinking bucket invented by Yang Shengqing was invented based on the purpose of completely separating “water and gas”. He just added a plastic film core to the usual drinking bucket, which is equivalent to a built-in plastic bag. The water is in the "bag" and the air circulates outside the "bag." During the entire discharge process, drinking water is completely isolated from the air. Dust and bacteria trapped in the air between the membrane and the wall of the drinking water tank will not settle on the surface of drinking water. It can effectively prevent harmful substances in the air from drinking water. Pollution. Due to the presence of the film core, the original drinking water bucket will not pollute the drinking water.

Double-layer bucket creative and environmentally friendly

It is understood that the double-decked drinking bucket is the idea of ​​SARS. At present, this work has already applied for national invention patents and utility model patents. There are now more than 10 manufacturers and manufacturers of drinking water and plastic film, companies and inventors contact, hope to cooperate with him. Yang Shengqing told reporters that the next plan was to raise a sum of money and contact the plastic film factory to mass produce some film cores to make the invention social and economic benefits as soon as possible.

Another advantage of a double-layer bucket is environmental protection. Usually the cost of a drinking bucket is 30 yuan, and the life span is only two or three years. At present, the country still needs about 80 million drinking water buckets per year to fill up the drinking buckets that have been eliminated due to the expiration date. In addition, drinking bins must be cleaned and disinfected after each use, which is not only time-consuming but also a waste of valuable water resources. The new drinking bucket and the original drinking fountain have a good matching function and can be used without having to make complicated modifications to the original drinking fountain, which is favorable for promotion.
