In one or more embodiments of the present invention, the filter material of the filter element 300 is a metal filter material or a non-metal filter material.

In one or more embodiments of the present invention, when the changeover switch 110 is positioned at the first position, the opening 1121 of the second water channel 112 faces the inner side of the outer casing 120 and is not aligned with the water inlet 121, and the opening of the first water channel 111 1111 is aligned with the water outlet 122. The first chamber 400 communicates with the water outlet 122 through the first water channel 111. The water inlet 121 communicates with the outer water channel 220 through the side flow channel 113. One end of the bracket 500 and the switch 110 is connected, and the limiting member 510 disposed at the other end of the bracket 500 is pressed against the drain valve 210 to close the drain valve 210. As shown in Figure 4. When the switch 110 is positioned at the first position, the water filter of the present invention can be operated in a filtering mode. Since the opening 1121 of the second water channel 112 faces the inner side of the outer casing 120 and is not connected to the water inlet 121, the water inlet 121 is The raw water to be filtered can flow into the side flow passage 113 through the opening 1131 of the side flow passage 113, and then flow into the outer circulation water passage 220 through the other opening 1132 of the side flow passage 113, and press the raw water into the inside of the filter element 300 by water pressure. The filtration becomes purified water, and the inside of the filter element 300 flows into the first water channel 111 through the first chamber 400 and the opening 1112 of the first water channel 111, and flows out through the water outlet 122 through the opening 1111 of the first water channel 111. Therefore, the raw water to be filtered flows in from the water inlet 121 and is filtered through the filter element 300, so that the purified water flows out from the water outlet 122, which is a function of filtering the purified water. The water flow diagram is shown in Figure 5.

In one or more embodiments of the present invention, when the changeover switch 110 is positioned at the second position, the opening 1121 of the second water channel 112 is aligned with the water inlet 121, so that the water inlet 121 is separated by the second water channel 112. A chamber 400 is open, and the opening 1111 of the first water channel 111 in the switch 110 is directed toward the inner side of the outer casing 120. The bracket 500 is actuated by the switch 110 to cause the limiting member 510 to release the drain valve 210 to make the drain valve 210 is turned on, as shown in Figure 6. When the switch 110 is positioned at the second position, the water filter of the present invention can be operated in a clean backwash mode. Since the opening 1121 of the second water channel 112 is aligned with the water inlet 121, the feed water of the water inlet 121 can be used by the first The opening 1121 of the second water channel 112 flows into the first chamber 400 through the other opening 1122 of the second water channel 112 without passing through the side flow path 113 provided on the side of the changeover switch 110. After the feed water flows into the second water channel 112 through the first chamber 400, it flows into the inside of the filter element 300, and the water pressure is forced to flow out of the outer side of the filter element 300 by the water pressure. The impurities adhering to the outer surface of the filter element 300 may be washed by the reverse water pressure, and the dirt flows out through the drain valve 210 as the sewage passes through the outer ring water passage 220. The water flow diagram is as shown in Fig. 7. Therefore, the feed water flows in from the water inlet 121, and after cleaning the impurities on the filter element 300 through the reverse filtration, the sewage is discharged from the drain valve 210, which is a function of the clean backwash. Accordingly, the present invention utilizes only the same water inlet 121, and the operation mode of filtering the raw water and cleaning the backwashing two different functions can be achieved by switching the operation of the switch 110 without changing the water inlet direction.

The filter element 300 can be quickly cleaned, and the dirt flows out of the open drain valve 210 as the sewage passes through the outer water channel 220. By the arrangement of the impeller 320, the water filter of the present invention can be made without additional power assistance, and only the water inlet is utilized. The water flow of 121 drives the filter element 300 to rotate, thereby improving the effect of backwashing. The water flow diagram is shown in Figure 7.

In one or more embodiments of the present invention, as shown in FIG. 2, at least one brush piece 221 is optionally disposed in the outer ring water channel 220 for brushing and adhering to the filter element 300 when performing the backwash function. The dirt on the outer wall is cleaned by the brush sheet 221 to adhere the viscous or large particles adhering to the outer surface of the filter element 300. Therefore, in the backwash mode operation, the changeover switch 110 is positioned at the second position, the feed water flows into the first chamber 400 from the water inlet 121 via the second water channel 112, and the water pressure flowing through the first chamber 400 simultaneously pushes the impeller 320 is actuated to further rotate the filter element 300 in the lower tank body 200, and the water flow then flows into the inside of the filter element 300, and the raw water is forced to flow out of the outer side of the filter element 300 by water pressure, and the outer surface of the filter element 300 is flushed by the reverse water pressure. And the rotating filter element 300 is brushed by the brush piece 221, so that the impurities outside the filter element 300 can be easily dropped, and the dirt flows out from the opened drain valve 210 as the sewage passes through the outer ring water channel 220. By the arrangement of the impeller 320, the water filter of the present invention can be made without additional power assistance, and only the water flow of the water inlet 121 drives the filter element 300 to rotate, thereby improving the backwashing effect.

As described above, the water filter of the present invention can extend the effective use period of the filter element by the backwashing process, thereby saving the time and cost required for replacement and maintenance, and filtering without causing disposable disposal. Consumables can save environmentally friendly processing costs. In addition, compared to the prior art, the water filter of the present invention can achieve the function of backwash without additional use of additional power assistance such as pump or mechanical rotation.
