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 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. Firstly, most of the existing faucet water purifiers, for example, the ceramic filter element or the activated carbon filter element, purify tap water, and the faucet water purifier using a single ceramic filter element or activated carbon filter element, because the ceramic filter element or activated carbon filter element has a large pore size, the tap water is not completely purified, and the obtained purified water is not suitable for direct drinking.
The chinese patent application No. 201811199228.2 discloses a tap water purifier for purifying tap water by using micro-filtration ceramic, activated carbon and ultra-filtration ceramic, wherein when the tap water purifier is used for treating tap water, the micro-filtration ceramic is firstly used for carrying out micro-filtration on the tap water, then the activated carbon is used for carrying out activated carbon filtration on purified water generated by the micro-filtration ceramic, and then the purified water generated by the activated carbon is further filtered by the ultra-filtration ceramic to generate ultra-filtration purified water. However, the faucet water purifier disclosed in this patent lacks a rinsing mechanism, and particularly a mechanism for rinsing the ultrafiltration ceramic, which results in a short period of time in which a large amount of impurities and microorganisms accumulate on the inner surface of the ultrafiltration ceramic membrane, clogging the ultrafiltration ceramic membrane. Even more, the accumulation of a large number of microorganisms causes the faucet water purifier provided by the patent of the invention to be likely to smell after being used for a short time.

As known to those skilled in the art, a faucet water purifier directly installed in a faucet has a small volume due to the limitation of a use space where the faucet water purifier is located. When the tap water purifier utilizes the ultrafiltration filter element, particularly the ultrafiltration filter element which takes the ultrafiltration membrane wire as the main filter element, the ultrafiltration filter element is easy to stink and cannot be used continuously because of the accumulation of tap water impurities, such as microorganisms and other impurities, attached to the surface of the ultrafiltration membrane wire. The filtering device 20 of the faucet water purifier of the present invention allows the purified water generated by the primary filter element 22 to be provided, and simultaneously, the purified water generated by the primary filter element 22 is further used to clean the surface of the ultrafiltration membrane wire 231 of the secondary filter element 23, thereby preventing impurities such as microorganisms in tap water from being accumulated in the secondary filter element 23 and preventing the impurities from smelling and being unable to be used continuously. In other words, the faucet water purifier of the present invention solves the problem that the traditional faucet water purifier is likely to generate impurity accumulation and cannot be discharged in time to cause odor when the traditional faucet water purifier uses the ultrafiltration filter element (or ultrafiltration membrane wire) to filter water through the ingenious structural design of the filtering device 20, so that the ultrafiltration membrane wire 231 of the secondary filter element 23 has a better filtering effect and the service life of the secondary filter element 23 is prolonged. More importantly, because the faucet water purifier has smaller volume, with the structure of the traditional faucet water purifier, when the ultrafiltration filter element is used for treating raw water such as tap water, blockage can occur in a short time. When the tap water purifier utilizes the purified water generated by the primary filter element 22, the tap water purifier has the flushing effect on the ultrafiltration membrane wire 231 of the secondary filter element 23, and the problem that impurities are gathered and cannot be discharged in time when the traditional tap water purifier uses the ultrafiltration filter element (or ultrafiltration membrane wire) to filter water is obviously solved, so that the tap water purifier can use the ultrafiltration filter element to filter water. The faucet water purifier of the invention has greater significance in that consumers can get rid of the traditional desk-top water purifier with large volume and high price.

At this time, since the second opening 1102 and the third opening 1103 of the valve body 11 are communicated with each other through the eighth communication channel 1008, the purified water generated by the first-stage filter element 22 after filtering flows into the purified water channel 2201, flows out from the second communication opening 202, and sequentially flows through the third opening 1103, the eighth communication channel 1008 and the second opening 1102, so that the purified water generated by the first-stage filter element 22 can be provided through the second water outlet 200 communicated with the second opening 1102.

As shown in fig. 20A to 21E of the drawings, accordingly, when the filter device 20D of the faucet water purifier according to the embodiment of the present invention is used to treat raw water, a user can control the flow of raw water to the first communication opening 201 of the filter device 20D through the control valve 10, at this time, if the raw water can freely flow through the second communication opening 202 of the filter device 20D under the control of the control valve 10, and the purified water generated by the primary filter 22D cannot freely flow to the third communication opening 203, the raw water will flow in from the first end 2211D of the ultrafiltration membrane wire 221D, flow out from the second end 2212D of the ultrafiltration membrane wire 221D, and then flow out from the second communication opening 202 and be provided. Raw water flows through the purified water passage 2201D, the membrane wire passage 2210D of the ultrafiltration membrane wire 221D, the second water chamber 2402D, the second communication opening 202 in this order, and is supplied. On the other hand, if the raw water cannot freely flow through the second communication opening 202 of the filtering device 20D under the control of the control valve 10, and the purified water generated by the primary filter element 22D can freely flow to the third communication opening 203, the raw water will flow in from the first end 2211D of the ultrafiltration membrane wire 221D under the action of the water pressure, and after the ultrafiltration treatment of the ultrafiltration membrane wire 221D, will be collected through the water collecting hole 2230D and the collecting channel 2231D of the collecting pipe 223D, and then flow out and be provided through the clean water outlet 2201D of the primary filter element 22D, the first water chamber 2401D and the third communication opening 203. Accordingly, the faucet water purifier according to the embodiment of the invention is in an ultrafiltration working state at this time.
As shown in fig. 20A to 21E of the drawings, the raw water passage 2101D, the membrane wire passage 2210D, the second water chamber 2402D of the base 24D, and the second communication opening 202D of the filter device 20D of the faucet water purifier according to the embodiment of the present invention form a raw water path, and the water collecting hole 2230D of the primary filter element 22D, the collecting passage 2231D, the purified water outlet 2201D, the first water chamber 2401D of the base 24D, and the third communication opening 203D of the filter device 20D form a purified water path. It will be appreciated that the raw water circuit and the purified water circuit are separated to prevent mixing of the water in the raw water circuit and the purified water circuit. In other words, the raw water path and the purified water path are separated to prevent raw water from being mixed into the purified water generated from the primary filter element 22D.
Preferably, the filtering means 20 of the faucet water purifier of the present invention employs an external pressure type ultrafiltration cartridge. In other embodiments, the filter device 20 of the faucet water purifier of the present invention employs an internal pressure type ultrafiltration cartridge. Because the membrane surface area of the contained internal pressure type ultrafiltration membrane filaments is smaller under the same volume of the ultrafiltration filter element, the water flow generated by the internal pressure type ultrafiltration filter element is relatively smaller, and therefore, when the internal pressure type ultrafiltration filter element is adopted, the ultrafiltration filter element is required to have a larger outer diameter or be thicker. This results in a larger volume of the internal pressure ultrafiltration cartridge for the same flow rate of purified water.
