the water is filtered downwards from the filter element 21 in a first stage and then flows out from the water outlet pipe 4, and the filtering is finished; in order to inject more water and accelerate the filtering speed, and meanwhile, the water flowing from other filter elements 21 is not influenced, the filtering effect is not influenced, the baffle 221 is rotatably connected to the first groove 22 through the torsion spring 222, and the two baffles 221 are closed under the action of the torsion spring 222 to prevent the water from flowing in; when the circular sleeve 6 is not displaced to the second groove 61 and is aligned with the first groove 22, the ring sleeve 611 is positioned inside the second groove 61, and the ring sleeve 611 abuts against the outer wall of the filter 2 through the elastic force of the spring 613; when the second groove 61 is aligned with the first groove 22, on one hand, the elastic force of the spring 613 pushes the ring sleeve 611 to move towards the first groove 22, the elastic force is transmitted to the baffle 221 through the ring sleeve 611, on the other hand, water flows into the second groove 61 in the round sleeve 6 from the water inlet hole, at the moment, the water pushes the stop block 612, the thrust of the water is transmitted to the ring sleeve 611 and then transmitted to the baffle 221, under the action of two forces, the torsion force of the torsion spring 222 is smaller than the sum of the elastic force of the spring 613 and the thrust of the water, and the baffle 221 can be opened by the ring sleeve 611 and extends into the first groove 22; after the water is filtered, the pushing force of the water transmitted to the stopper 612 disappears, the torsion of the torsion spring 222 is greater than the pushing force of the spring 613, and the baffle 221 is closed, so that the ring sleeve 611 is reset; the end of the ring sleeve 611 is provided with a chamfer, when the round sleeve 6 is displaced to the required filter element 21 and is not aligned with the first groove 22, the ring sleeve 611 can slide out of the second groove 61 under the action of the spring 613, and the chamfer is designed to ensure that the ring sleeve 611 cannot be clamped on the outer wall of the filter 2 and can slide into the first groove 22 through the chamfer; when water filtration is finished, the round sleeve 6 moves downwards, and when the ring sleeve 611 moves downwards, the round sleeve slides out of the first groove 22 through the chamfer and finally abuts against the outer wall of the filter 2, so that the resetting effect of the ring sleeve 611 is stably realized; when the ring sleeve 611 moves against the outer wall of the filter 2, the friction between the ring sleeve 611 and the outer wall of the filter 2 is changed from sliding friction to rolling friction by the balls 615 contacting the outer wall of the filter 2, so that the friction force is reduced; when water is injected into the ultra-filtration water purifier from the water inlet pipe 3, the water drops under the action of gravity and contacts the top of the filter 2 firstly, and the top of the filter 2 is designed into an inverted triangle shape, so that the water can slide onto the round sleeve 6 under the action of gravity; because the annular groove 62 is formed in the upper end face of the round sleeve 6, the vertical section of the annular groove 62 is in an inverted triangle shape, water can be collected at the bottom of the annular groove 62, and then flows into the second groove 61 of the round sleeve 6, and then enters the filter 2 through the first groove 22 for filtering; the top of the filter 2 is in an inverted triangle shape, the upper end face of the round sleeve 6 is provided with the annular groove 62, and the vertical section of the annular groove 62 is in an inverted triangle shape, so that the water can be guided; the baffle plates 221 are close to the groove wall of the first groove 22 and close to the top end of the filter 2, and are rotatably connected to the wall of the filter 2 through the torsion springs 222, so that the two baffle plates 221 can be tightly closed under the action of the torsion springs 222; meanwhile, the relative position of the baffles 221 in the closed state has reached the maximum, and when the baffles 221 rotate, the distance between the tops of the two baffles 221 close to each other will gradually increase, so that the two baffles 221 will not collide with each other, and at the same time, water can be prevented from flowing into the filter 2 from the closed baffles 221.
