Water storage box

Abstract

A water storage box comprises a box body, a box cover and a flexible inner container. A bag opening of the flexible inner container is fixed to the box cover. A first cavity is formed in the flexible inner container. A second cavity is formed between the flexible inner container and the box body. The box cover is provided with a water inlet, a water outlet and an air hole, wherein the water inlet is communicated between the first cavity and an external water inlet device; the water outlet is communicated between the first cavity and an external water outlet device; the air hole is communicated with the second cavity and outside atmosphere; a valve device is arranged in the first cavity and opposite to the water inlet, and the valve device can close or open the water inlet along with the water level in the first cavity; a water outlet pipe connected with the water outlet is further disposed in the first cavity. The water storage box has the advantages that the structure is simple and compact, water outflow is stable, water can be automatically supplemented, water does not make contact with air, and the water storage box is healthy and hygienic.

Description

technical field [0001] The invention relates to a water storage tank. Background technique [0002] Existing water storage tanks mainly include a tank body and a tank cover that covers the tank mouth of the tank body. When in use, a suction pipe is directly inserted into the tank body from the tank cover, and the water pump and microcomputer in the water use device are used to control the water. Provide water supply for water installations. The disadvantages of this water storage tank are: 1. When using water, the water will flow out from the water storage tank due to the water absorption of the straw, which will easily form a vacuum in the water storage tank. External air must enter the water storage tank to fill the vacuum to continue to discharge water, resulting in The outlet water flow rate is not large and unstable, and at the same time, the external air will carry bacteria and so on into the water in the water storage tank to pollute the water in the water storage ta...

Problems solved by technology

The disadvantages of this water storage tank are: 1. When using water, the water will flow out from the water storage tank due to the water absorption of the straw, which will easily form a vacuum in the water storage tank. External air must enter the water storage tank to fill the vacuum to continue to discharge water, resulting in The water flow rate is not large and unstable, and at the same time, the outside air will carry bacteria into the water in the water storage tank to pollute the water in the water storage tank, which is extremely unsafe for drinking

2. This kind of water storage tank cannot be connected with the water purifier, so that automatic water replenishment cannot be realized, and it needs to be replaced in real time, which is inconvenient to use and also restricts people from drinking fresher, more hygienic and safer water
