Background

With the increasing improvement of living standard and the increasing emphasis on health, the quality requirement of people on domestic water is higher and higher. On the other hand, however, many countries, especially developing countries, have increasingly serious water pollution problems with the continuous development of agriculture and industry, which inevitably leads to the water source of domestic water, especially tap water, being affected either lightly or heavily. In addition, the quality of tap water is affected by the external environment and water supply pipelines. For example, the water source of tap water has an increased sand content, which leads to a deterioration of the quality of the tap water. The quality of tap water can be influenced by lack of cleaning and aging of a tap water supply pipe network for a long time. Thus, in many cases, tap water is not suitable for direct drinking. In order to solve the above problems of the tap water, various household water purification apparatuses, such as an ultrafiltration water purifier, an RO membrane water purifier, a faucet water purifier, and the like, have appeared on the market to purify the tap water. Among these water purification units, faucet water purifiers are popular with many consumers because of their advantages of small size, convenient assembly and disassembly, and the ability to automatically purify tap water under tap water pressure without the need of electric power. However, the existing faucet water purifier also has a plurality of defects. For example, the filter element is easily clogged after treating raw water (or tap water) for a certain period of time.

Accordingly, when the raw water flows into the raw water passage 2101E and is treated by the primary filter element 22E by the water pressure, the produced purified water flows out from the purified water outlet 2201E of the primary filter element 22E. Therefore, the raw water passage 2101E is located at one side of the primary filter element 22E, and the purified water outlet 2201E is formed at an opposite side. Preferably, the primary filter element 22E is a ceramic filter element. It is understood that the primary filter element 22E may also be a filter element made of other materials, or a composite filter element made of multiple materials, such as a composite filter element made of any two or more of ceramic, carbon fiber, PP wool, and activated carbon particles.

As shown in fig. 2A to 4C of the drawings, the filter device 20E of the faucet water purifier according to the first embodiment of the present invention has a first communication opening 201E and a second communication opening 202E, wherein the first communication opening 201E of the filter device 20E communicates with the raw water passage 2101E of the filter device 20E, so that the control valve 10E can supply raw water to the filtering means 20E through the first communication opening 201E, the second communication opening 202E of the filtering device 20E is communicated with the purified water outlet 2201E of the primary filter element 22E, so that the purified water produced by the primary cartridge 22E can flow out through the second communication opening 202E, and under the control of the control valve 10E, through the utility model discloses a first delivery port 100E or a hot water outlet 9103 of tap water purifier is provided for the user. In other words, the purified water produced by the first-stage filter element 22E of the filtering device 20E of the faucet water purifier flows to the second communication opening 202E of the filtering device 20E under the action of the water pressure.

As shown in fig. 2A to 4C and fig. 11A to 11E of the drawings, correspondingly, when the filtering device 20E of the faucet water purifier according to the first embodiment of the present invention is used for treating raw water, a user can control the raw water to flow to the first communicating opening 201E of the filtering device 20E through the control valve 10E, the raw water flows to the raw water channel 2101E of the filtering device 20E under the action of water pressure, the raw water is treated by the primary filter 22E under the action of water pressure, and then the generated purified water flows from the purified water outlet 1E of the primary filter 22E to the second communicating opening 202E of the filtering device 20E under the action of water pressure, and flows out and is provided from the second communicating opening 202E under the control of the control valve 10E. Correspondingly, this moment according to the utility model discloses this leading water purifier of first embodiment is in a first filtration operating mode or a second filtration operating mode. Further, when according to the utility model discloses this filter equipment 20E of this leading water purifier's of first embodiment this control valve 10E control raw water back flush, user's accessible this control valve 10E control raw water flow direction this second intercommunication opening 202E of this filter equipment 20E, raw water flows to this pure water export 2201E of this one-level filter core 22E of this filter equipment 20E under hydraulic effect, and under hydraulic effect, this one-level filter core 22E of back flush, the sewage of formation flows to this first intercommunication opening 201E of this filter equipment 20E from this raw water passageway 2101E under hydraulic effect, and flow out from this first intercommunication opening 201E under this control valve 10E's control. Correspondingly, this moment according to the utility model discloses this leading water purifier of first embodiment is in a back flush operating condition.
