Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Reference Figures 1-3This utility model provides an embodiment of a household water collection and reuse device, including a washbasin 1. A collection component 2 is provided at the bottom of the washbasin 1. The collection component 2 includes a box 21, which is square in shape. A water inlet pipe 22 is fixedly connected to the top of the box 21. A filter component 23 is fixedly connected inside the box 21, below the water inlet pipe 22. A water outlet pipe 24 is fixedly connected to the bottom of the box 21, and a water pump is fixedly connected to the end of the water outlet pipe 24 away from the box 21. 3. The inlet of the water pump 3 is connected to the outlet pipe 24. An angle valve 4 is installed on the pipe at the end of the water pump 3 away from the outlet pipe 24. The end of the water pump 3 away from the outlet pipe 24 is fixedly connected to the toilet 5 through a pipe. The angle valve 4 is installed in the pipe between the water pump 3 and the toilet 5. The inlet pipe 22 is fixedly connected to the bottom of the basin 1. The height of the collection component 2 is higher than that of the water pump 3. The filter component 23 is higher than the outlet pipe 24. The diameter of the filter pipe 237 is larger than that of the inlet pipe 22. The diameter of the filter pipe 237 is smaller than that of the drain outlet 235.
[0011] Reference Figures 2-3 The filter assembly 23 includes a plug 231 with an anti-slip groove at the bottom and a thread 232 on the outside. Support rods 233 are uniformly fixedly connected to the top of the plug 231, and scrapers 234 are uniformly fixedly connected to the outside of the support rods 233. The diameter of the support rods 233 is smaller than the width of the scrapers 234. A drain port 235 is threadedly connected to the outside of the plug 231, and a threaded groove 236 is provided inside the drain port 235. The thread 232 and the threaded groove 236 are threadedly matched. A filter pipe 237 is fixedly connected to the bottom of the inlet pipe 22, and filter holes 238 are uniformly provided on the outside of the filter pipe 237. The scrapers 234 are slidably connected to the filter pipe 237. Inside the filter pipe 237, the diameter of the scraper 234 is smaller than the diameter of the filter pipe 237. The end of the scraper 234 away from the plug 231 is higher than the filter hole 238. The height of the filter hole 238 is lower than the support rod 233. The drain port 235 is fixedly connected to the bottom of the box 21. The diameter of the drain port 235 is smaller than the filter assembly 23. The box 21 is set below the basin 1. The filter hole 238 is opened on the outside of the filter pipe 237 and is lower than the height of the box 21. The support rod 233 is located inside the filter assembly 23. The height of the support rod 233 is lower than the filter pipe 237. The plug 231 is threadedly connected to the drain port 235. The filter pipe 237 is higher than the drain port 235.
[0012] Working principle: When the washbasin 1 is in use, wastewater enters the collection component 2 through the inlet pipe 22. The wastewater first enters the filter component 23 and then flows into the tank 21. During this process, because the filter pipe 237 has filter holes 238, impurities in the wastewater are trapped inside the filter pipe 237. The wastewater discharged after passing through the filter holes 238 then flows into the tank 21. When the toilet 5 needs water, the angle valve 4 is opened, and the water pump 3, connected to the outlet pipe 24, draws wastewater from the tank 21 to supply water to the toilet 5. When the water supply is complete, the water pump 3 is turned off. With angle valve 4, wastewater will remain inside toilet 5 for use. When the filter assembly 23 needs to be cleaned, rotate the plug 231. Since the support rod 233 is fixedly connected to the plug 231 and the scraper 234 is fixedly connected to the support rod 233, when the plug 231 rotates, the scraper 234 will gradually move downwards along the inner wall of the filter pipe 237, carrying out the impurities deposited inside the filter pipe 237, keeping the filter pipe 237 and filter hole 238 clean. When in use, the plug 231 is threadedly connected to the internal thread groove 236 of the drain outlet 235 through the thread 232, so that the box 21 is in a closed state.
[0013] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
