[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, the present utility model provides a technical solution: a self-flushing filter water purification device, comprising: a filter water purification device main body 1, a handle 2, a filter screen mechanism 3, a partition baffle 4, a drain port 5, an electric telescopic rod 6, a connecting block 7, a water delivery pipe 8, an annular water pipe rack 9, a flushing nozzle 10, a limiting groove 11, a limiting block 12, a hydrophobic baffle 13, a rotating handle 14, a spring 15, a blocking door 16, a blocking rod 17 and a connecting groove 18;

[0029] When using this self-flushing filter water purification device, as Figure 1 and Figure 4 shown, hold the two handles 2 on the upper side of the filter water purification device main body 1, take out the filter water purification device main body 1 from the device and place it on the ground. The electric telescopic rod 6 is located inside the filter water purification device main body 1. The electric telescopic rods 6 are symmetric about the vertical central axis of the filter water purification device main body 1, and a connecting block 7 is fixedly connected to the upper side of the electric telescopic rod 6. A water delivery pipe 8 is arranged between the connecting blocks 7. The two electric telescopic rods 6 distributed front and back can make the water delivery pipe 8 rise smoothly, preventing the annular water pipe rack 9 from colliding with the inner side of the filter screen mechanism 3 during lifting and lowering. Then, remove the threaded cap on the connecting pipe on the upper side of the water delivery pipe 8 from the upper side of the water delivery pipe 8, and connect an external water source to the connecting pipe of the cap;

[0030] As Figure 1 and Figure 4 shown, the partition baffle 4 divides the filter screen mechanism 3 into three equal-sized parts inside the filter screen mechanism 3. A sliding groove for the upper and lower lifting of the connecting pipe of the annular water pipe rack 9 and the annular water pipe rack 9 is arranged in the middle of the partition baffle 4. Start the electric telescopic rod 6, and the electric telescopic rod 6 will drive the water delivery pipe 8 to lift and lower through the connecting block 7. The lifting and lowering of the water delivery pipe 8 will cause the annular water pipe rack 9 to lift and lower together, so that the flushing nozzle 10 will lift and lower together. The lifting and lowering flushing nozzle 10 will spray the external water from the flushing nozzle 10 onto the filter screen mechanism 3 and the partition baffle 4. In addition, the flushing nozzles 10 are arranged in an array on the outer side of the annular water pipe rack 9. The flushing nozzles 10 arranged in an array will perform a more complete flushing on the filter screen mechanism 3 and the partition baffle 4, making the flushing effect better;

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when purifying water, the hydrophobic baffle 13 still closely adheres to the lower side of the filter screen mechanism 3, so that the drain opening 5 opened in front of the lower side of the filter screen mechanism 3 is still limited by the hydrophobic baffle 13, preventing water resources from being discharged without passing through the filtration of the filter screen mechanism 3. During flushing, since large impurities may be contained inside the filter screen mechanism 3 and the partition baffle 4, and cannot be discharged from the lower side of the filter screen mechanism 3, it is necessary to open the hydrophobic baffle 13 to allow these impurities to be discharged to the outside from the drain opening 5. Push the turning handle 14 to the left to disconnect the limiting block 12 from the limiting groove 11. At this time, the spring 15 will undergo elastic deformation, and under the action of gravity, the other side of the hydrophobic baffle 13 will drop. At this time, the drain opening 5 will no longer be blocked by the hydrophobic baffle 13, and the sewage carrying impurities can be discharged from the inside of the filter screen mechanism 3. After the impurities are discharged from the inside of the filter screen mechanism 3, turn the turning handle 14 to make the hydrophobic baffle 13 closely adhere to the lower side of the filter screen mechanism 3 again, blocking the drain opening 5, and then pull the spring 15 to the right to make the limiting block 12 snap into the limiting groove 11 again. The spring 15 plays a limiting role on the limiting block 12 to prevent the limiting block 12 from disconnecting from the clamping groove of the limiting groove 11 in case of vibration, resulting in water being discharged without passing through the filtration of the filter screen mechanism 3;

[0032] As Figure 2 and Figure 5 shown, a door 16 is rotatably connected to the front side of the main body 1 of the filter screen water purification device, and a blocking rod 17 is slidably connected to the main body 1 of the filter screen water purification device through a connecting ring. Under normal circumstances, the lower end of the blocking rod 17 is clamped in the connecting groove 18 to prevent the blocking rod 17 from moving and disconnecting the limiting effect on the door 16, resulting in the sewage carrying impurities being directly discharged to the outside during the flushing process, dirtying the flushing environment. In addition, the blocking rod 17 and the connecting groove 18 are symmetric about the vertical central axis of the main body 1 of the filter screen water purification device, further playing a role in reinforcement.
