Air isolation structure for drinking bucket

Abstract

The invention discloses an air isolation structure for drinking bucket, including a drinking bucket, a bucket cover, a sleeve barrel and a water sac, wherein, the drinking bucket is provided with a bucket neck and a bucket mouth; the bucket cover is opened with an air hole and a water hole, the water hole is provided with a plug for preventing the water in the bucket from overflowing; the sleeve barrel includes a barrel and a barrel cap, the barrel is a hollow straight pipe, a terminal port of the barrel everts to form the barrel cap; the water sac is used for filling water and has a sac neck and a sac mouth; the water sac and the sleeve barrel are jointly provided in the inner cavity of the drinking bucket, the water sac is sleeved on the barrel of the sleeve barrel through the sac neck, the barrel cap is suspended on the bucket mouth of the drinking bucket, and the inner wall of the drinking bucket and the out wall of the water sac forms a space for storing air; the inner wall of the bucket neck, the bucket mouth rim and the out wall of the water sac neck, the barrel, the barrel cap and the bucket cover jointly constitute an air ingress and egress channel which is communicated to the air storing space. The invention completely isolates the water in the drinking bucket and the air entering into the bucket, so as to avoid the secondary pollution of the bacilli and dust in the air to the drinking water, and the invention will not damage the structure of drinking bucket for facilitating storage and transportation, and is also applicable to automatized filling production line of barrelled water.

Description

technical field [0001] The invention relates to an air isolation structure on a drinking water container, in particular to a structure for isolating water in a drinking bucket from air entering the bucket. Background technique [0002] When people drink water, due to the difference in air pressure inside and outside the drinking bucket, air must enter the bucket from the mouth of the bucket, so that the water in the bucket can flow out normally, which will inevitably bring dust and bacteria in the air into the water, making the inside of the bucket of pure water is polluted. [0003] In order to solve this problem, the utility model 02294689.6 proposes an air-insulated water dispenser bucket, which includes: a hard outer bucket and an inner bucket made of flexible materials in the outer bucket, and there are air holes on the barrel body of the outer bucket. Air is allowed to enter the space between the outer barrel and the inner barrel. This bucket realizes the isolation o...

AI Technical Summary

Problems solved by technology

This bucket realizes the isolation of water and air, and solves the secondary pollution problem of air to pure water, but the shortcomings of this drinking bucket are very obvious: 1. The structural integrity of the bucket is destroyed, and the shock resistance of the drinking bucket is reduced; 2. In the process of transportation and storage, the sharp object pierces the flexible inner barrel through the hole on the barrel body, and the water will leak out from the air hole; 3. It is inconvenient to put the flexible inner barrel into the outer barrel; 4. It is not suitable for bottled water automatic filling production line
