Description

Drinking water barrel

Technical field

The utility model relates to the technical field of design of drinking water containers, in particular to a drinking water tank.

Background technique

With the improvement of people's living standards, people pay more and more attention to their own health. As an indispensable necessities in our daily lives, drinking water products are increasingly on the market. Bottled water is one of the more popular drinking water products. Users often get drinking water from bottled water in their homes, offices and public places. Bottled water can greatly facilitate the user's demand for pure water, but there are also health hazards.

Drinking water tanks are water containers for bottled water, and drinking water tanks play an important role in ensuring the cleanliness and hygiene of bottled water. At present, there are a large variety of drinking water tanks on the market, which can prevent secondary pollution of water to a certain extent, but the effect is limited. We know that, considering the cost, the drinking water tank is usually used repeatedly. When the drinking water in the drinking water tank is consumed, the empty drinking water tank will be transported to the drinking water plant for filling the drinking water. In this process, the drinking water tank is more likely to be contaminated, so that the bottled water after refilling is more likely to be contaminated.

Based on this, please refer to Figure 1-3, which is a schematic diagram of a typical drinking water tank during the filling process. The drinking water tanks shown in Figures 1-3 are more common, including a barrel body 01 and a flexible film bag 02 built into the barrel 01. The flexible film bag 02 is used for holding water and is a disposable product, each time it is filled. Both of them are filled with water into the new flexible film bag 02. Obviously, this can improve the cleanliness of the bottled water, and the flexible film bag 02 can isolate the water from the barrel 01, which can further prevent the bottled water from being contaminated. In the current filling process, the bag mouth of the flexible film bag 02 needs to be everted outside the barrel mouth of the barrel 01 during the filling process, which makes the irrigation production line need to increase the device for opening the bag mouth. After the watering is completed, the lid 03 is closed, and when the watering is completed, it is easy to cause more pocket edges 021 to be exposed outside the lid 03, which not only causes the flexible film bag 02 to pass through the exposed bag mouth more easily. The edge 021 is torn and also affects the aesthetics of the bottled water product.

In order to solve this problem, the current drinking water production line needs to increase the cutting mechanism to expose the flexible film bag 02 to the excess bag edge 021 outside the lid 03. The above-structured drinking water tank requires a filling production line to increase the opening mechanism and the cutting mechanism, which in turn increases the complexity of the filling production line and also increases the cost of the filling production line.
