Secondary pollution-free direct drinking water storage barrel device

Abstract

The invention relates to a secondary pollution-free direct drinking water storage barrel device, and belongs to the technical field of plastic products. The device is composed of a barrel body (1), ahigh-elasticity telescopic bag (2), a bag opening conversion device (3) and a water valve (4); and the high-elasticity telescopic bag (2) is similar to the latex balloon and is arranged in the barrelbody (1), and the bag opening of the high-elasticity telescopic bag is fixed at the end of the barrel opening through the bag opening conversion device (3), and then is in butt joint with the water valve (4) through reserved water inlet and outlet pipe threads of the bag opening conversion device (3) to control water inlet and outlet. The elastic telescopic bag (2) filled with water keeps positivepressure in the bag all the time under the action of the elasticity, thus water can be automatically discharged without gas-water replacement or external force during water taking, water taking equipment is saved virtually, pollution sources are effectively avoided, and the problem of secondary pollution is avoided. Therefore, the quality guarantee period of the water is not affected by the watertaking process, so that the direct drinking safety of the whole-barreled water is ensured. The device is more simple, convenient and safe to use.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a direct drinking water storage bucket device without secondary pollution. Background technique [0002] Water is the source of all life. The water in the human body accounts for 75%-85% of the total weight of the human body. Water participates in the whole process of metabolism in the human body. Therefore, people have to consume a lot of water every day to maintain the normal operation of the body. Under normal circumstances, an adult needs to drink about 2500 milliliters of water every day, but the quality of drinking water is directly related to the health of the human body and the length of life. According to the World Health Organization's survey, 80% of human diseases are related to water, which fully demonstrates the importance of drinking water to human health. With the rapid development of society, water sources have also been damaged and polluted ...

Problems solved by technology

Although some merchants have introduced disposable soft-packed drinking water that can avoid secondary pollution, due to factors such as its small capacity and inconvenient transportation and use, it has not been able to replace bottled water for more than ten years.

[0004] In addition, in the prior art, there is a kind of pressure water storage tank, which uses a flexible inner tank (or air bag) to store water, and its outer layer is a sealed high-strength pressure tank; when storing water, it must first be stored in the pressure tank. Inject air to squeeze out the air in the inner tank and seal it, and then use the pressure to pour water into the inner tank, so that a certain pressure will be generated between the inner tank and the pressure barrel, and the pressure will increase with the increase of the water volume. Therefore, it must Set over-pressure protection; when taking water, just open the water outlet valve, under the action of the air pressure in the bucket, the water will automatically overflow, and the pressure will decrease as the water volume decreases. Once the outer bucket leaks, it may not be able to out of water

Besides, its water storage capacity is only about half of the volume of the pressure tank, and the sealing requirements of the inner and outer layers are very high, and the structure is also relatively complicated, which invisibly increases a lot of technical difficulty and cost, and the efficiency is obviously not high, so it is only suitable for some special places
