According to the investigation of the world health organization, 80% of human diseases are related to water, which fully explains the importance of drinking water to human health, so that the quality of drinking water directly influences the health and the life of people. However, with the rapid development of society, water sources are damaged and polluted to different degrees, and the life style of people is greatly changed in addition to the urbanization process. As for the living drinking water on which people live, the drinking water is not limited and meets the requirement of pipeline tap water for a long time. Therefore, various packaged drinking water is produced, wherein bottled water and barreled water are always favored by consumers and become an indispensable part of daily life of people. However, the existing barreled water is not like bottled water, and although the barreled water is safe and can be directly drunk during packaging, the barreled water has a large capacity, and can not be used up in three or five days after being unsealed, even more than twenty days or more, and water can be discharged only by water-gas replacement during water taking, so that secondary pollution is inevitably caused by using the traditional pure barreled water, which is a fact of no conflict. In fact, the bottled water cannot be directly drunk after being opened for more than five days, and must be boiled for drinking, otherwise, potential safety hazards can be brought to the body. The secondary pollution problem of the barreled drinking water can be said to be eye-catching, and the drinking water machine, the water barrel and the air are pollution sources; especially, the air-water replacement when the barreled water is taken is the most inevitable secondary pollution process, the quality of the residual drinking water in the barrel is directly influenced by the replaced air, and the drinking water is easily mistakenly drunk if the barreled water is not used up in time after being unsealed, so that the body is damaged. Nowadays, along with the development of society, people's consciousness to food safety is constantly promoted, and traditional bottled water has been unable to satisfy people's life requirement, so, the improvement and the innovation of straight drinking water packaging technology are especially urgent.

The applicant provides a direct drinking water storage barrel device (patent No. 2019206235757) without secondary pollution, which is an improvement and innovation of the traditional pure hard barrel for storing direct drinking water, can avoid secondary pollution caused by the traditional barreled water in the water taking process, and greatly prolongs the quality guarantee period of the barreled direct drinking water after being sealed. However, in practice, the high-elasticity inner bag is made of latex, and because the processing and manufacturing process of the high-elasticity latex bag is relatively complex, the difficulty is higher when the high-elasticity latex bag reaches the food grade, peculiar smell is inevitably generated, and the water quality is more difficult to avoid being influenced when the high-elasticity latex bag is used for storing drinking water; particularly, the latex inner bag is easy to age and deteriorate and lose elasticity after being contacted with water for a long time, so that the practical significance of automatic water discharge and reutilization by utilizing the elasticity is lost.
