Detailed Description

A water storage device, see fig. 1 to 6, comprises a tank body 1 and an isolation component 2. A first partition plate 11 is arranged in the tank body 1, and the first partition plate 11 divides the inner cavity of the tank body 1 into a raw water chamber 12 and a concentrated water chamber 13 which are arranged in parallel. The first partition plate 11 is provided with a communication passage 14, the communication passage 14 has a first communication port 141 communicating with the raw water chamber 12, and the communication passage 14 further has a second communication port 142 communicating with the concentrated water chamber 13. The isolation assembly 2 includes a valve 21, the valve 21 being disposed within the communication passage 14, the valve 21 having a first operating position and a second operating position. When the valve 21 is in the first operating position, the communication passage 14 is open, and water in the concentrate chamber 13 can flow from the communication passage 14 into the raw water chamber 12. When the valve 21 is in the second working position, the communication channel 14 is closed, the raw water chamber 12 and the concentrated water chamber 13 are independent of each other, and water in the concentrated water chamber 13 cannot flow into the raw water chamber 12.

Compared with the prior art, the water storage device of the embodiment connects the raw water chamber 12 and the concentrated water chamber 13 through the communication channel 14, and the connection or disconnection of the raw water chamber 12 and the concentrated water chamber 13 is controlled through the valve 21. Before the initial operation of the water purifying drinking machine, the whole tank 1 can be completely filled with raw water, namely the raw water fills the raw water chamber 12 and the concentrated water chamber 13, the space of the tank 1 is fully utilized, and the valve 21 is at the first working position. During the operation of the water purifying and drinking machine, raw water flows out of the tank 1, concentrated water flows into the concentrated water chamber 13, the outflow rate of the raw water is greater than the inflow rate of the concentrated water, the water in the concentrated water chamber 13 flows into the raw water chamber 12, and the water levels in the two chambers gradually drop. When the water level in the raw water chamber 12 drops to a certain level, the valve 21 is switched from the first working position to the second working position, the valve 21 closes the communication channel 14, and the water quality in the concentrated water chamber 13 does not meet the water source requirement of the water purification system, so that the water in the concentrated water chamber 13 is prohibited from flowing into the raw water chamber 12.

Referring to fig. 1 to 6, in order to reduce raw water pollution and improve space utilization of the tank 1, the first communication port 141 is located above the second communication port 142. The aquatic granule in the dense water cavity 13 can deposit in the bottom of dense water cavity 13 or communicating channel 14, and the water of keeping away from dense water cavity 13, communicating channel 14 bottom can be cleaner, lets comparatively clean rivers go into former water cavity 12, helps reducing the pollution of the water in the former water cavity 12. Meanwhile, the water in the concentrated water chamber 13 can flow into the raw water chamber 12 as much as possible, and the space utilization rate of the box body 1 is further improved.

Referring to fig. 1 to 6, in order to further reduce raw water pollution and improve the space utilization of the tank 1, a raw water outlet 121 is provided at the bottom of the raw water chamber 12.
