Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, and more specifically, to a rainwater harvesting and filtration device. Background Technology

[0002] Resource scarcity has become a global problem. When traditional water resource development methods can no longer increase water sources, rainwater recycling has become an economical and practical water resource development method. Rainwater, as a non-traditional resource, has multiple functions, and reasonable rainwater collection and utilization can greatly facilitate our lives.

[0003] However, most existing rainwater harvesting and filtration devices do not have the ability to self-clean during use, which means that after use, the filter screen inside the device needs to be disassembled and cleaned frequently by hand, which is quite laborious. Furthermore, the extension distance of the recycling pipe cannot be flexibly adjusted, which means that when the recycling device is used indoors, the water receiving mechanism cannot directly contact the rainwater, thus affecting the flexibility of the device during use.

A guide rod 20 is fixedly provided on the outer wall of the recycling box 1 and on one side of the threaded rod 18, and the other end of the movable plate 17 is slidably installed with the guide rod 20.

[0023] More specifically, when the water filter assembly 2 needs to be cleaned, pressurized water can be guided into the curved pipe 7 through the cleaning pipe 6. At this time, it will spray out from the bottom of the nozzle 8 to achieve the effect of rinsing the water filter assembly 2. The wastewater will then fall into the bottom of the recycling tank 1. At this time, the valve 29 can be opened to discharge the wastewater from the waste discharge pipe 28 for continued use. When using the device indoors, the user can turn the handwheel 19 to rotate the threaded rod 18.

[0024] Please see Figure 1 , Figure 2 and Figure 5 As an embodiment for disassembling and cleaning the water filter assembly 2: The water filter assembly 2 includes a square frame 21. The inside of the square frame 21 is provided with a stainless steel sintered mesh layer 22 and a fine filter screen 23. The stainless steel sintered mesh layer 22 and the fine filter screen 23 are arranged sequentially from bottom to top. A support frame 24 is fixedly provided on the inner wall of the recovery box 1 at the bottom. The bottom of the square frame 21 is in contact with the upper end of the support frame 24, and the upper end of the square frame 21 is in contact with the bottom of the conical block 4. An outlet 25 is opened on the outer wall of the square frame 21 on one side. The outlet 25 is located at the upper end of the fine filter screen 23.

[0025] Specifically, when the user needs to disassemble and replace the water filter assembly 2, the fastening nut 10 can be turned to disengage it from the threaded post 9.

[0026] Please refer to Figure 2 As a further implementation method for draining filtered rainwater: a water outlet pipe 26 is provided on the outer wall of the recycling bin 1, and the water outlet pipe 26 is located on one side of the water outlet 25.

[0027] Specifically, during the collection process, the filtered rainwater will flow out from the outlet pipe 26 to facilitate subsequent collection.

[0028] In summary, during operation, rainwater enters the bottom of the recovery tank 1 through the collection funnel 15 and recovery pipe 14, and after being filtered by the water filter assembly 2, flows out from the outlet 25, achieving the effect of collection and filtration. Residue inside the rainwater is trapped at the bottom by the stainless steel sintered mesh layer 22 and the fine filter screen 23. After use, pressurized water is guided into the curved pipe 7 through the cleaning pipe 6, and then sprayed from the bottom of the nozzle 8 to rinse the water filter assembly 2. Wastewater then falls to the bottom of the recovery tank 1, at which point the valve 29 can be opened to discharge the wastewater from the waste drain pipe 28 for later use. Continuing to use the device indoors, the user can rotate the handwheel 19 to rotate the threaded rod 18. At this time, the threaded rod 18 will drive the moving plate 17 and the telescopic tube 13 to move, so that they gradually open, thereby allowing the recovery tube 14 and the collection funnel 15 to extend outdoors, making it convenient to collect rainwater, which increases the flexibility of the device when in use. When the user needs to disassemble and replace the water filter assembly 2, the user can rotate the fastening nut 10 to disengage it from the threaded column 9. At this time, the cover 3 and the recovery box 1 can be separated, and the water filter assembly 2 can be slid out from the inside of the recovery box 1 for easy replacement, which helps with long-term use.
