[0028] The filter structure 4 includes a plurality of first filter screens 401, which are all arranged inside the filter box 3. The angle between the side of the first filter screen 401 facing the water flow direction and the water flow direction is less than 90°. The first filter screen 401 is provided with filter holes with flow diversion, and the extension direction of the filter holes coincides with the water flow direction, so that the distance of water flow between two adjacent first filter screens 401 is greater than the vertical distance between the two corresponding adjacent first filter screens 401, that is, the distance a is greater than the distance b. Filter material is filled between two adjacent first filter screens 401. When in use, water is filtered by the filled filter material, and a plurality of filter areas are formed by the first filter screen 401, which is convenient for sequential filtration to improve the filtering effect. The filter material can be made of quartz sand particles.

[0029] An inner cylinder 402 is installed between two adjacent first filter screens 401, and the inner cylinder 402 is connected to the inner wall of the filter box 3; the inner cylinder 402 and the filter box 3 are connected in a detachable manner, and multiple first filter screens 401 are combined into a whole through multiple inner cylinders 402, so as to facilitate the overall removal and replacement inside the filter box 3.

[0030] A second filter 403 is installed on the top of the first filter 401, and filter materials are filled between the first filter 401 and the second filter 403 for filtering the water flowing in the filter box 3; filter holes are provided on the second filter 403, and the diameter of the filter holes on the second filter 403 is the same as the diameter of the first filter 401; the diameters of the filter holes of the multiple first filters 401 gradually decrease from bottom to top, and the particle size of the filter materials decreases successively from bottom to top, which is convenient for intercepting impurities and improving utilization rate.

[0031] The cross-sectional shape of the first filter 401 is V-shaped, and the cross-sectional shape of the second filter 403 is an inverted V-shape. The axis of the filter holes on the second filter 403 is vertically distributed, which plays a role in guiding the water flow to flow vertically upward along the filter holes, thereby increasing the distance in the filter area, thereby improving the filtering effect of the filter area on water.

[0032] The top water inlet of the water tank 1 is connected to the top water outlet of the filter box 3 through a first pipe, and the bottom water inlet of the filter box 3 is connected to the output end of the liquid conveying mechanism through a second pipe.

At the same time, due to the flow of water, the filter material will also move, and the finer filter material will gradually move upward, and the filter material particles will gradually decrease from bottom to top, and the gaps between the particles will gradually decrease, so that the coarser particles can intercept larger impurities, thereby improving the utilization rate of the filter structure 4 and making the larger impurities located at the bottom for easy discharge during flushing.

[0034] The filter box 3 includes a box body and a top cover. The box body is installed on the outside of the water tank 1. The water inlet at the bottom of the box body is connected to the output end of the liquid conveying mechanism through a second pipe. The top of the box body is detachably connected to the top cover, and the top of the top cover is connected to the water tank 1 through a first pipe. The box body and the top cover can be detachably fixed by bolts, and a sealing ring is provided between the two to maintain the seal, so that the box body can be opened to replace the filter material that needs to be replaced.

[0035] A set of flow velocity detection components and turbidity detection components 5 are installed in the box body, which are used to detect the flow velocity and turbidity of the water flow before filtration. Another set of flow velocity detection components and turbidity detection components 5 are installed in the top cover. The two sets of flow velocity detection components and turbidity detection components 5 are respectively located above and below the filtering structure 4, and are used to detect the flow velocity and turbidity of the water flow after filtration. The two sets of turbidity detection components 5 and the flow velocity detection components are respectively communicated with the control system; when in use, by detecting the flow velocity and turbidity before and after filtration, the flow velocity difference and turbidity difference before and after are obtained. When the flow velocity difference is large or the turbidity difference exceeds the set value, it means that the filter material in the filtration area is abnormal, and the filter material needs to be flushed or replaced, so that the smart water personnel can take corresponding measures according to the suggestions of the smart water system.

[0036] The first pipeline includes a second connecting pipe 7 and a third connecting pipe 8, both ends of the third connecting pipe 8 are connected to the top cover and the water tank 1 respectively, the interior of the third connecting pipe 8 is connected to the end of the second connecting pipe 7, the second connecting pipe 7 and the third connecting pipe 8 are respectively connected to the control component for opening or closing the third connecting pipe 8 and the second connecting pipe 7; the second connecting pipe 7 is connected to an external flushing water source and is used for water intake when flushing the filter material, the control component on the third connecting pipe 8 is located on the side close to the water tank 1, which is convenient for cutting off the passage with the water tank 1, and the third connecting pipe 8 and the second connecting pipe 7 are both soft pipes, which is convenient for disassembly of the top cover.

[0037] The second pipeline includes a first connecting pipe 6, the top of which is connected to the bottom of the box body, the first connecting pipe 6 has one end of a fourth connecting pipe 9, the other end of the fourth connecting pipe 9 is connected to the liquid conveying mechanism, the first connecting pipe 6 and the fourth connecting pipe 9 are respectively connected to the control component for opening or closing the first connecting pipe 6 and the fourth connecting pipe 9; the control component on the first connecting pipe 6 is located at one end close to the bottom, so as to facilitate cutting off the passage between the first connecting pipe 6 and the outside, the first connecting pipe 6 opens downward and is connected to a pipeline for recovering flushing waste water, so as to facilitate the recycling of water resources; the control component includes four solenoid valves, which are respectively installed on the first connecting pipe 6, the second connecting pipe 7, the third connecting pipe 8 and the fourth connecting pipe 9, and the four solenoid valves are respectively communicated with the control system to facilitate the control of the first connecting pipe 6, the second connecting pipe 7, the third connecting pipe 8 and the fourth connecting pipe 9.

[0038] When filling water, the water level in the water tank 1 is constantly monitored by the water level detection component 2. After the water level drops to the set value, the detection data is fed back to the control system, and the solenoid valves on the second connecting pipe 7 and the first connecting pipe 6 are controlled to close, and the solenoid valves on the third connecting pipe 8 and the fourth connecting pipe 9 are opened. Then, the liquid conveying mechanism is controlled to allow external water to enter the filter box 3 through the fourth connecting pipe 9 and part of the first connecting pipe 6, and the water is discharged from the top of the filter box 3 after being filtered by the filtering structure 4, and enters the water tank 1 through the third connecting pipe 8, thereby realizing automatic water filling of the water tank 1.

If the filtering effect is still poor or abnormal after multiple cleanings, the filter structure 4 is disassembled to avoid frequent disassembly of the filter structure 4.
