[0028] Referring to the drawings in the specification, a simple filtering structure includes a main body 10. In use, the interior of the main body is a hollow cylinder, and the main body is provided with an inlet channel 11 and a water outlet chamber 12 that can be connected. The main body is provided with a first water outlet 13 and a second water outlet 14 that are connected to the water outlet chamber. A filter screen 20 is provided at the water inlet end of the first water outlet. In use of the present invention, a water source (municipal water) flows from the water inlet channel to the water outlet chamber, and then a stream of water flows out from the first water outlet after being filtered by the filter screen, while another stream of water flows out from the second water outlet. At the same time, the water flow will flush impurities attached to the filter screen and remove the impurities from the second water outlet, thereby overcoming the problem of the filter screen being blocked, so that the water outlet component can be used for a long time without affecting its function.
[0029] The present invention further provides a water inlet 15 between the water inlet channel and the water outlet chamber, and a sealing device 30 for controlling the interruption of water flow is provided at the water inlet; when the water outlet assembly of the present invention is in a water-flowing state, the sealing device does not seal the water inlet, thereby maintaining smooth water flow at the water inlet; and when the water outlet assembly needs to be disassembled, the sealing device can seal the water inlet, and no water leakage will occur.
[0030] Preferably, the blocking device includes a limit plate 31, which can be fixed in the main body. Preferably, the limit plate is fitted in the water inlet channel through a threaded connection. The limit plate is provided with a water through hole 311 and a mounting hole 312. The water through hole is used to direct the water flow from the water inlet channel to the water outlet chamber. A movable shaft 32 is provided in the mounting hole, and one end of the movable shaft is inserted in the mounting hole. A sealing gasket 33 is also provided on the periphery of the movable shaft. The sealing gasket can be connected with the water inlet to control the water flow interruption of the water inlet. When the sealing ring contacts and cooperates with the water inlet, the water flow is cut off. A spring 34 is provided between the movable shaft and the limit plate. When the present invention is in use, when the water outlet chamber does not need to pass water, the movable shaft will move toward the water outlet chamber under the action of the spring and the water flow. At this time, the sealing gasket will be connected with the water inlet to cut off the water flow, and under the action of the spring and the water flow, the water flow is always cut off.
[0031] Furthermore, an annular flange 35 is provided on the outer periphery of the movable shaft, and the spring is located between one end face of the annular flange and the limiting plate, thereby ensuring the effective operation of the spring. The other end face of the annular flange is connected to the sealing gasket, and the stability of the sealing ring and the water inlet when they are matched can be ensured through the surface contact, and there will be no misalignment and leakage. In a preferred use, the outer diameter of the annular flange is not less than the outer diameter of the sealing gasket.
[0032] Preferably, a boss 36 is provided on the side of the movable shaft facing the water outlet chamber, and an annular groove 37 is formed between the boss and the other end face of the annular flange. The sealing gasket is located in the annular groove. The sealing gasket is clamped in the annular groove to ensure that the sealing gasket moves synchronously with the movable shaft and at the same time ensure its stability when cooperating with the water inlet.
[0033] In a preferred embodiment of the present invention, it also includes a handle assembly 40, which is located in the water outlet chamber. The handle assembly includes a push rod 41, and the filter screen is arranged on the outer periphery of the push rod. The push rod can be used to control the blocking device. The push rod can be in contact with the movable shaft. When the push rod is installed, the blocking device is in the state of blocking the water inlet. When the push rod is installed in place, the push rod will overcome the water flow pressure and the action of the spring to open the water inlet and start the water flow state.
[0034] Furthermore, a connecting piece 42 is arranged in an arc shape on the outer peripheral side of the push rod, and the filter is located at the connecting piece. In this embodiment, the filter can be annular, and a water channel 43 is formed between adjacent connecting pieces. A first annular body 44 is arranged on the side of the push rod close to the water inlet, and a water outlet 45 is arranged between the first annular body, the connecting piece and the push rod. After the water flows into the water outlet cavity, it first flows from the water outlet to the water channel, and then flows from the water channel to the filter, and flows out from the first water outlet after being filtered by the filter.
[0035] Furthermore, a second annular body 46 is provided on the other side of the push rod, and the filter screen and the first water outlet are located between the first annular body and the second annular body, so that it can be ensured that the filter screen can filter the water flowing to the first water outlet, and the outer periphery of the first annular body and the second annular body is sleeved with a sealing ring 50 that can seal with the inner circumferential wall of the water outlet cavity, that is to say: water flows in from the water outlet to the water channel, and then flows out from the first water outlet after being filtered by the filter screen, ensuring that the water flowing out from the first water outlet is filtered by the filter screen. Preferably, the second water outlet is located on the side of the first annular body facing the water inlet, because the water output from the second water outlet has no requirements on water quality and can contain impurities, and it can also ensure that the water flow will not flow from the handle and the water outlet cavity to the outside of the main body, thereby avoiding water leakage.
[0036] Preferably, a groove 47 is provided on one end face of the push rod facing the water inlet, and a guide slope 48 is provided in the groove. The blocking device includes a movable shaft, and the movable shaft can be inserted into the groove. When the push rod is installed, the guide slope is pre-positioned with the movable shaft to ensure that the installation can be completed quickly. At the same time, after the installation of the handle assembly is completed, the bottom surface of the groove bottom is abutted with the end surface of the movable shaft.

[0038] In the present invention: 1. Open state: the handle pushes the movable shaft open, and water can flow from the water inlet to the water outlet chamber; 2. Closed state: the handle is unscrewed, and under the action of the spring and water pressure, the movable shaft and the sealing gasket block the water inlet of the body; 3. When water flows through the filter screen, impurities will be intercepted by the filter screen; 4. Under the action of the water flow, the impurities in the filter screen will be washed out from the second water outlet; 5. The filter screen can be integrally formed with the handle or assembled on the handle.
[0039] In a preferred use of the present invention, it is used on a toilet, a water source is connected to a water inlet channel, water from a first water outlet is connected to a water inlet end of a buttocks washing / female washing function to ensure hygienic use, and water from a second water outlet is connected to flushing water of the toilet, and the water used for flushing has no hygienic requirements, and impurities in the water source can be flushed out together.
