In many countries, especially in developing countries, with the continuous development of industry and agriculture, the problem of water pollution is more and more serious, and the water source of domestic water for people is also influenced slightly or heavily. In addition, the quality of tap water is affected by the external environment and water supply pipelines. For example, the quality of tap water is affected by excessive sand in the tap water source, aging of the pipe network, poor quality of the tap water pipe, lack of cleaning of the water supply pipe network for a long time, and the like. Thus, tap water in many countries is of poor quality and unsuitable for direct consumption, under the influence of a number of factors. The water purifier can effectively remove impurities such as silt, colloid, rust, bacteria and even heavy metal ions in raw water, thereby improving the quality of domestic water and being increasingly favored by consumers. The existing household water purifier for purifying tap water mainly comprises an under-kitchen ultrafiltration water purifier, an RO membrane water purifier, a faucet water purifier and the like. Among these water purifiers, the under-kitchen ultrafiltration water purifier, the RO membrane water purifier, and the like are limited in their application fields due to their complicated structures and large volumes. The tap water purifier has the advantages of small volume, convenient installation and disassembly, capability of automatically purifying tap water under the pressure of the tap water without electric energy and the like, and is popular among many consumers. However, the existing faucet water purifier also has a plurality of defects.

The primary filter element 22H forms the clean water outlet 2201H. It is understood that the raw water inlet 1105H is adapted to communicate with a source of raw water.

As shown in fig. 4 of the drawings, when the control valve 10H of the faucet water purifier according to the embodiment of the present invention controls the water flow to flow out from the first opening 1101H of the filtering device 20H, the raw water flows from the raw water inlet 1105H to the primary filter 22H under the action of the water pressure, and flows to the raw water passage 2101H and the first opening 1101H under the action of the water pressure, and the primary filter 22H is flushed while the raw water flows to the first opening 1101H, and accordingly, the faucet water purifier of the present invention is in a flushing state. Preferably, when the faucet water purifier of the present invention is in the flush state, no water can flow out of the clean water outlet 2201H of the primary filter element 22H. As shown in fig. 5 of the drawings, when the control valve 10H of the faucet water purifier according to the embodiment of the present invention controls the water flow to flow out from the purified water outlet 2201H of the filtering device 20H and not to flow out from the first opening 1101H, the raw water flows into the raw water channel 2101H from the raw water inlet 1105H under the action of the water pressure and is treated by the primary filter element 22H under the action of the water pressure, and the generated purified water flows out from the purified water outlet 2201H of the primary filter element 22H and is provided. Accordingly, at this time, the faucet water purifier of the present invention is in a purification state. Preferably, the raw water passage 2101H is located at one side of the primary filter cartridge 22H, and the purified water outlet 2201H is formed at an opposite side of the primary filter cartridge 22H.

Accordingly, when the faucet water purifier of the present invention is in a purification state, raw water flows into the raw water passage 2101H from the raw water inlet 1105H by water pressure and is treated by the primary filter element 22H by water pressure, and the resulting purified water flows out from the purified water outlet 2201H of the primary filter element 22H and further flows out and is supplied through the third opening 1103H and the fourth opening 1104H. Preferably, the second opening 1102H and the fourth opening 1104H are formed in the spool 12H in a spaced apart relationship.

As shown in fig. 4 of the drawings, the control valve 10H of the faucet water purifier according to the embodiment of the present invention has a flushing operation position, wherein when the control valve 10H is in the flushing operation position, the valve core 12H of the control valve 10H is rotated to make the second opening 1102H of the valve core 12H communicate with the first opening 1101H. Accordingly, when the control valve 10H is in the flushing position, the raw water or tap water flows from the raw water inlet 1105H, the raw water passage 2101H, and then flows to the second opening 1102H of the valve core 12H through the first opening 1101H. Therefore, when the control valve 10H is in the flushing position, the primary filter element 22H is flushed by the raw water under the action of the water pressure, and the generated sewage can be discharged through the first opening 1101H and the second opening 1102H in sequence. It can be understood that, when the control valve 10H of the faucet water purifier according to the embodiment of the present invention is controlled to be at the flushing position, the sewage generated by flushing the first-stage filter element 22H with raw water under the action of water pressure flows out from the first opening 1101H (or the second opening 1102H). At this time, the faucet water purifier of the present invention is controlled to be in its flushing state. Preferably, the third opening 1103H is blocked by the valve body 12H when the faucet water purifier of the present invention is in the flushing state.

As shown in fig. 5 of the drawings, the control valve 10H of the faucet water purifier according to the embodiment of the present invention further has a cleaning operation position, wherein when the control valve 10H is in the cleaning operation position, the valve core 12H of the control valve 10H is rotated until the first opening 1101H of the valve body 11H of the control valve 10H is blocked by the valve core 12H, and the third opening 1103H of the valve body 11H of the control valve 10H is communicated with the fourth opening 1104H of the valve core 12H.
