The specific embodiment is a water inlet pipe fitting for a drum washing machine, and its structural schematic diagram is shown in Figures 1, 2, 3 and 4, including a connecting hose 1, a connecting pipe 4 is connected to the lower end of the connecting hose 1, a filter cartridge 6 is threadedly connected to the connecting pipe 4, a movable plate 12 is movably installed at the bottom of the filter cartridge 6, a limit assembly 8 is installed on the lower surface of the movable plate 12, the upper end of the filter cartridge 6 is threadedly connected to the connecting pipe 4, the connecting pipe 4 is provided with a threaded interface pipe adapted to the filter cartridge 6, an upper filter hole 9 is provided on the upper surface of the filter cartridge 6, a side filter hole 10 is provided above the side of the filter cartridge 6, an intermediate pipe 3 is rotatably connected to the upper end of the connecting hose 1, a connecting head 2 is fixedly connected to the upper end of the intermediate pipe 3, the connecting head 2 is threadedly connected to the faucet, the connecting pipe 4 is threadedly connected to a threaded pipe 7, the threaded pipe 7 is arranged on the washing machine, a sealing ring 5 is fixedly installed in the connecting pipe 4, and a side of the sealing ring 5 away from the threaded pipe 7 is fixedly installed above the inside of the connecting pipe 4 by gluing, and the sealing ring 5 is adapted to the threaded pipe 7. The movable plate 12 is equipped with two groups of symmetrically distributed sliders 11, and the filter cartridge 6 is provided with a vertically arranged groove 13. The slider 11 is slidably adapted to the groove 13. When the faucet is turned on, the tap water then enters the middle tube 3 through the connector 2, and then the water flows into the connecting hose 1, and the water flows into the connecting pipe 4 through the connecting hose 1, and then the water flows into the filter cartridge 6, and finally the water flows into the washing machine through the threaded tube 7. When the water flows through the filter cartridge 6, the water flows first into the lower part of the filter cartridge 6, and the lower part of the filter cartridge 6 is a solid design. After the water flows into the filter cartridge 6, the water level rises until the water flows out through the side filter holes 10 and the upper filter holes 9. When the water flows into the filter cartridge 6, it also brings mud and sand into the filter cartridge 6. Since the mud and sand have a greater specific gravity than water, the mud and sand will be deposited in the lower part of the filter cartridge 6 (in actual use, the filter cartridge 6 can be set longer so that the mud and sand are completely deposited in the lower part of the filter cartridge 6), and the water flows out through the side filter holes 10 and the upper filter holes 9.

2, 3 and 5, the limiting assembly 8 includes a mounting box 803, which is fixedly mounted at the center of the lower surface of the movable plate 12. A circular hole 802 is provided on the side of the mounting box 803, and a connecting rod 808 is slidably passed through the circular hole 802. There are two groups of connecting rods 808, and the ends of the connecting rods 808 are connected to a pasting plate 805, and the pasting plate 805 is arranged with a curved surface, and the pasting plate 805 is in contact with the inner wall of the filter cartridge 6. The end of the connecting rod 808 away from the pasting plate 805 is connected to a pressing plate 807, and there are two groups of pressing plates 807. Multiple groups of springs 804 are installed between the two groups of pressing plates 807. Pull plates 806 are provided on the lower surfaces of the two groups of pressing plates 807. The mounting box 803 is provided with a slide groove that is slidably adapted to the pull plates 806. A plug 801 is installed at the center of the side away from the connecting rod 808, and a socket that is slidably matched with the plug 801 is opened at the lower part of the inner wall of the filter cartridge 6. The pull plate 806 is pressed in the direction of approaching each other, and the movement of the pull plate 806 drives the pressure plate 807 to move, and the movement of the pressure plate 807 drives the connecting rod 808 to move. When the pressure plate 807 moves, the spring 804 is compressed synchronously, and when the connecting rod 808 moves, the sticking plate 805 is driven away from the filter cartridge 6, and the movement of the sticking plate 805 drives the plug 801 to be separated from the socket on the side wall of the filter plate, and the limit of the movable plate 12 is released. Then the movable plate 12 is taken out, and the sediment retained on the upper surface of the movable plate 12 is cleaned, and the filter cartridge 6 is cleaned. After cleaning, it is reinstalled.

Working principle: When the water inlet pipe is actually used, the connector 2 is connected to the tap (the tap has an internal thread, that is, the outer wall of the water outlet of the tap is provided with a thread), and then the connecting pipe 4 is connected to the threaded pipe 7 of the washing machine. When connected, the sealing ring 5 is in close contact with the upper end of the threaded pipe 7 to play a sealing role, which can prevent water from overflowing from the gap between the connecting pipe 4 and the threaded pipe 7. When the tap is turned on, the tap water then enters the intermediate pipe 3 through the connector 2, and then the water flows into the connecting hose 1, and then the water flows into the connecting pipe 4 through the connecting hose 1, and then the water flows into the filter cartridge 6, and finally the water flows into the washing machine through the threaded pipe 7;

When the water flows through the filter cartridge 6, the water flows firstly into the lower part of the filter cartridge 6, and the lower part of the filter cartridge 6 is solid. After the water flows into the filter cartridge 6, the water level rises until the water flows out through the side filter holes 10 and the upper filter holes 9. When the water flows into the filter cartridge 6, the silt is also brought into the filter cartridge 6. Since the silt has a higher specific gravity than water, the silt will be deposited in the lower part of the filter cartridge 6 (in actual use, the filter cartridge 6 can be set longer so that the silt is completely deposited in the lower part of the filter cartridge 6). The water flows out through the side filter holes 10 and the upper filter holes 9.

When it is necessary to uniformly deal with the mud and sand inside the filter cartridge 6, the connecting pipe 4 is screwed out from the threaded pipe 7 on the washing machine, and then the filter cartridge 6 is taken out from the threaded pipe 7, and then the filter cartridge 6 is screwed out from the connecting pipe 4. At this time, the limit assembly 8 is used to release the limit on the movable plate 12. The specific method is to squeeze the pulling plate 806 in the direction of approaching each other, and the movement of the pulling plate 806 drives the pressure plate 807 to move, and the movement of the pressure plate 807 drives the connecting rod 808 to move. When the pressure plate 807 moves, the spring 804 is compressed synchronously. When the connecting rod 808 moves, it drives the sticking plate 805 away from the filter cartridge 6. The sticking plate 805 moves and drives the plug 801 to disengage from the socket on the side wall of the filter plate, thereby releasing the limit on the movable plate 12. Then the movable plate 12 is taken out, and the mud and sand retained on the upper surface of the movable plate 12 is cleaned, and the filter cartridge 6 is cleaned. After cleaning, it is reinstalled.

Finally, it should be noted that the above 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 aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
