Embodiment 3

[0076] The present invention also provides embodiment 3, which differs from embodiment 1 and embodiment 2 in that the structure of the water storage device 73 adopted is different. In embodiment 3, the water storage device 73 includes a water tank and a first pressure pump, and the water tank It communicates with the pure water outlet pipe 72 for receiving and storing pure water. The first pressure pump pressurizes the pure water in the water tank when the filter device stops running, so that the pure water enters the filter bottle from the water tank through the pure water outlet pipe 72 The pure water chamber 50 among the 74 enters into the filter core from the water inlet side of the filter core to flush.

[0077] A filter system provided by the present invention adopts the filter device of the above-mentioned embodiment 1, embodiment 2 or embodiment 3.

Abstract

The invention discloses a filtering device and a filtering system. The filtering device comprises a shell, a filter element, a valve and a water storage device, wherein a pure water cavity is formed between the shell and the filter element, the valve is arranged between the pure water cavity and a central pipe and is opened when water pressure at the side of the central pipe is greater than waterpressure at the side of the pure water cavity; and the water storage device is communicated with the pure water outlet to receive pure water and sends the stored pure water to the pure water cavity when the valve is opened. According to the filtering device and the filtering system adopting such a structure, the water storage device is used for backflushing of the filter element, the TDS value ofthe first cup of water obtained after the filtering device or the filtering system stops working for a long time can be effectively reduced; and the water storage device directly flows back into the pure water cavity through the pure water outlet, so a pipeline and a related switch valve do not need to be additionally arranged outside, overall structure is simple, and manufacturing cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a filter device and a filter system. Background technique [0002] The main component of the reverse osmosis water purification device is the reverse osmosis membrane filter element, which generally has three water inlets and outlets: water inlet, pure water outlet and concentrated water outlet. By pressurizing the side of the water inlet, the municipal tap water enters the filter element through the water inlet, and then the tap water is filtered through the reverse osmosis membrane, and the filtered pure water is discharged to the water storage tank or the faucet through the pure water outlet. Various heavy metal ions, impurities and harmful substances that have penetrated the reverse osmosis membrane accumulate on the concentrated water side and are discharged through the concentrated water outlet. [0003] When the reverse osmosis water purification device is shut do...
