Referring to fig. 1 to 3, a filter element 100 is provided. The filter element 100 comprises a filter element body 10, a waterway switching valve 20 and an automatic flushing valve 30, wherein the filter element body 10 is provided with a water inlet, a water outlet and a sewage outlet; the waterway switching valve 20 is provided with a first flow passage and a second flow passage, the waterway switching valve 20 has a filtering position and a flushing position, when the waterway switching valve 20 is in the filtering position, the first flow passage is communicated with an external water inlet and the water inlet of the filter element body 10, and the second flow passage is communicated with an external water outlet and the water outlet of the filter element body 10; when the waterway switching valve 20 is in the flushing position, the first flow channel is communicated with an external water inlet and a water inlet of the filter element body 10, and the second flow channel blocks the external water outlet and/or a water outlet of the filter element body 10; the automatic flushing valve 30 is communicated with the sewage draining outlet, and the automatic flushing valve 30 is opened and closed at regular time. Specifically, when the filter element 100 is in normal operation, the automatic flushing valve 30 is opened at intervals to flush the filter element 100. At this time, the water path switching valve 20 is in the filtering position. After water at the external water inlet flows into the water inlet of the filter element body 10 from the first flow channel, when the automatic flushing valve 30 is in a closed state, the water flows out from the water outlet of the filter element body 10 after being filtered by the inside of the filter element body 10 under the action of external water pressure. When the automatic flushing valve 30 is in a closed state, water flowing in from the external water inlet flushes the filter element body 10, and then flows out from the opened automatic flushing valve 30 through the sewage draining outlet. However, some water may still remain in the filter cartridge body 10 or flow out of the water outlet of the filter cartridge body 10. The automatic flush valve 30 has insufficient flushing effect. Therefore, in order to sufficiently flush the filter element body 10, the waterway switching valve 20 is adjusted to the flushing position, and at this time, since the second flow passage is closed, when the automatic flushing valve 30 is opened, all the water flowing from the external water inlet flows into the automatic flushing valve 30 through the sewage outlet, so that the filter element body 10 is sufficiently flushed. As such, the filter cartridge 100 has multiple modes of operation. The first is normal use of the cartridge 100 and conventional flushing of the cartridge body 10. The waterway switching valve 20 is at the filtering position. Secondly, when the impurities accumulated on the filter element body 10 are too much, the filter element needs to be fully washed, and the waterway switching valve 20 is located at a washing position.
Referring to fig. 4, in an embodiment, the waterway switching valve 20 further includes a third flow channel, the waterway switching valve 20 further has a water stopping position, when the waterway switching valve 20 is located at the water stopping position, the first flow channel blocks the outside water inlet and/or the water inlet of the filter element body 10, the second flow channel blocks the outside water outlet and/or the water outlet of the filter element body 10, and the third flow channel communicates the outside water inlet and the outside water outlet. When the waterway switching valve 20 is located at the water-stopping position, the water flow does not flow into the filter element body 10, so that the filter element body 10 or the automatic flushing valve 30 can be replaced without affecting the whole waterway, and the leakage of the water flow does not occur.
Referring to fig. 2 to 4, in an embodiment, the filter element body 10 includes a housing 11 and a filter element assembly, the filter element assembly is disposed inside the housing 11, the filter element assembly includes an upper end cover 14 and a filter element 12, a water inlet and a water outlet of the filter element body 10 are disposed on the upper end cover 14, the housing 11 is provided with a through hole for avoiding the upper end cover 14, and an edge of the upper end cover 14 is hermetically connected to the housing 11. To prevent leakage, seals are provided at each pipe connection and at the connection of the edge of the upper end cap 14 and the inner wall of the housing 11. Optionally, the seal is a sealing ring 18. By the arrangement, a water inlet and a water outlet do not need to be additionally arranged on the shell 11, the water path structure is simplified, and the manufacturing difficulty and the manufacturing cost of the filter element 100 are reduced. Furthermore, the waterway switching valve 20 can be directly connected into the waterway inside the filter element body 10 through the upper end cover 14, so that the difficulty in mounting the waterway switching valve 20 on the filter element body 10 is reduced. Further, a sealing ring 18 is also disposed at a connection portion between the waterway switching valve 20 and the housing 11 to prevent water from leaking to the outside.
Referring to fig. 2 to 4, in an embodiment, the filter assembly further includes a lower end cap 15, a central tube 13 is formed inside the filter 12, an upper end of the central tube 13 is communicated with the water outlet of the filter element body 10, the lower end cap 15 is connected to a lower end of the filter 12, the lower end cap 15 is provided with a plugging portion for plugging a lower end of the central tube 13, and besides the plugging portion, the lower end cap 15 is further provided with at least one through hole communicated with the sewage drain. Thus, when the waterway switching valve 20 is in the flushing mode, water flows in through the water inlet of the filter element body 10, flows out from the through hole of the lower end cover 15 after the filter body 12 is flushed, and flows out from the sewage outlet. Further, in order to ensure the sewage discharge effect, a gap is arranged between the lower end cover 15 and the bottom end of the shell 11, and the gap is communicated with the through hole of the lower end cover 15 and the sewage discharge port.
Referring to fig. 2 to 5, in an embodiment, the filter body 12 includes a first filter body 12a and a second filter body 12b, the central tube includes a first central tube 13a disposed in the first filter body 12a and a second central tube 13b disposed in the second filter body 12b, a lower end of the first central tube 13a communicates with an upper end of the second central tube 13b, an upper end of the first central tube 13a is connected with the upper cover, a lower end of the second central tube 13b is connected with the lower cover 15, and a side wall of the second central tube 13b is provided with a through hole. Optionally, the present invention provides a filter element 100 with an automatic flushing function, and the filter material used for the filter element which is often required to be provided with the automatic flushing function has a higher cost. Therefore, in the case of poor water quality, the life of the filter medium which plays a main purification role is ensured. Specifically, the present invention provides a filter cartridge 100 having a composite structure, in which water flowing from the external water inlet is pretreated by the first filter 12a and then flows into the second filter 12b to purify the water. It is worth noting that when the waterway switching valve 20 is located at the filtering position, it is finally required that the water flow is purified by the first filtering body 12a and the second filtering body 12b in sequence, in order to ensure that the water flow treated by the first filtering body 12a does not directly flow out from the water outlet of the filter element body 10, the side wall of the first central tube 13a is not provided with a through hole, and the side wall of the second central tube 13b is provided with a through hole. After being filtered by the first filter 12a and the second filter 12b, the purified water flows into the second central tube 13b from the side wall of the second central tube 13b, and then flows into an external water outlet through the first central tube 13a in sequence.
Referring to fig. 5, in an embodiment, the filter assembly further includes a cylindrical connector 16 and a sleeve 17, the first filter 12a and the second filter 12b are connected by the cylindrical connector 16, the upper end cap 14 covers an opening of the cylindrical connector 16, the first filter 12a is disposed inside the cylindrical connector 16, a communication hole for communicating the first center tube 13a and the second center tube 13b is disposed at the bottom of the cylindrical connector 16, a through hole for passing water is disposed at the bottom of the cylindrical connector 16 except for the communication hole, the upper end and the lower end of the sleeve 17 are respectively connected with the cylindrical connector 16 and the lower end cap 15, and the second filter 12b is disposed inside the sleeve 17. Specifically, the cylindrical connecting member 16 and the sleeve 17 divide the interior of the housing 11 into two relatively independent filtering spaces, thereby facilitating the installation of the first filtering body 12a and the second filtering body 12 b. Furthermore, the sleeve 17 and the side wall of the cylindrical connecting piece 16 also ensure that, in the case of external pressure filtration, the water flow does not flow out from the side of the filter body 12, but down or into the central tube. I.e. the arrangement of the sleeve 17 and the cylindrical connection piece 16 further ensures the filtering effect.
Referring to fig. 5, in an embodiment, communication holes are formed at the bottoms of the upper end cover 14, the lower end cover 15, and the cylindrical connecting member 16, and the remaining parts except the communication holes are all hollow structures. For convenience of processing, the upper end cover 14 and the lower end cover 15 are similar structures which are convenient for processing. The hollow structure can allow more water to flow into the filter element body 10, thereby increasing the filtering speed of the filter element 100.
In one embodiment, the first filter 12a is a nonwoven fabric filter or a sponge filter, and the second filter 12b is an ultrafiltration filter. Wherein the first filtering body 12a mainly plays a role of pre-treating water in advance, and the second filtering body 12b mainly plays a role of purifying water. Thus, depending on the different functions performed by the different filter bodies 12. Different kinds of filter materials are adopted as the filter bodies. Specifically, the sponge filter body or the non-woven fabric filter body mainly plays a role in filtering large-particle impurities in water. The Ultrafiltration (UF) technology is a membrane separation technology between microfiltration and nanofiltration, has an average pore size of 3-100 nm, and has functions of purifying, separating, concentrating a solution, and the like. The interception mechanism mainly comprises the sieving effect and the electrostatic effect of the membrane, the filtering medium is an ultrafiltration membrane, and only low molecular weight solute and water can pass through the ultrafiltration membrane under the driving of pressure difference at two sides, so that the purposes of purification, separation and concentration are achieved. That is, the ultrafiltration filter body 12 plays the most important role in the filter cartridge 100 of the present invention, affecting the final purification effect. The cost of the ultrafiltration filter material is high, and the membrane filaments of the ultrafiltration filter material accumulate impurities in transaction, so that the service life and the filtering effect are influenced. When the automatic flushing valve 30 is opened, the water flow mainly flushes the membrane filaments of the ultrafiltration filter material to flush the impurities accumulated on the membrane filaments, thereby prolonging the service life of the filter element 100.
Referring to fig. 5, in an embodiment, the housing 11 includes a housing body 11b and a housing cover 11a, the housing cover 11a covers an opening of the housing body 11b, the filter assembly is disposed inside the housing body 11b, the housing cover 11a is detachably connected to the housing body 11b, and the housing cover 11a is provided with a through hole for avoiding the upper end cover 14. In this manner, the filter body 12 inside the filter cartridge 100 can be easily replaced. Or when other parts in the shell 11 are damaged, the maintenance is convenient.
