Description

Technical Field

[0001] The present invention relates to the technical field of filter water purifier equipment, and particularly to a parallel nanofiltration and ultrafiltration filter water purifier. Background Art

[0002] The design of a parallel double ultrafiltration filter element, through the parallel connection of two PVDF ultrafiltration membranes, can increase the purified water flow rate. A parallel water purifier is a device that improves the purified water efficiency and water quality by connecting multiple filtration devices in parallel. It consists of multiple independent filtration devices. The water source is connected to each filtration device through an integrated water circuit board, and the filtered water is collected and output. It can supply water with a large flow rate and can also use the purified water from one end of the filter element to backwash the filter element at the other end, realizing the mutual backwashing between the filter elements and extending the service life.

[0003] Among them, when backwashing the filter element with purified water, the pressure of tap water is often used to impact the filter element of the water purifier to wash the filter element. However, since the purified water needs to pass through multiple pipes, the impact force of the purified water will decrease, which may lead to insufficient impact force, making it difficult to effectively peel off the pollutants on the surface of the filter element and affecting the backwashing effect. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a parallel nanofiltration and ultrafiltration filter water purifier, which includes two filter tanks. The parts contained inside the two filter tanks are the same. The tops of the two filter tanks are connected through a water inlet pipe, and two valves I are rotatably connected to the inner wall of the water inlet pipe; A flow splitting mechanism, at the top of which a filtering component is fixedly installed, and at the bottom of which a drainage component is installed. The filtering component is used for filtering tap water; A flushing mechanism, which is installed on the inner wall of the flow splitting mechanism and is used for flushing the filtering component; and A flow disturbing mechanism, which is located on the inner wall of the flow splitting mechanism and is used for disturbing the flushing liquid; An extrusion block is slidably connected to the inner wall of the filter tank, a water delivery pipe is connected through the inner wall of the filter tank, a water collecting frame is rotatably connected to the outer wall of the water delivery pipe, and a water spraying pipe is connected through the bottom of the water collecting frame; Among them, tap water is injected into the flow splitting mechanism, and the tap water is filtered by the filtering component. At the same time, when the filtering component is dirty, the filtering component is flushed by the flushing mechanism to peel off the solid impurities on the surface of the filter element, making the filter element unblocked again and facilitating the filtration of tap water again. Then, the flushing liquid is disturbed by the flow disturbing mechanism to enhance the impact force of the liquid.

[0005] Preferably, the flow splitting mechanism includes: A filtering component, which is fixedly arranged at the top of the filter tank and is used for filtering tap water; The drainage component is fixedly arranged at the bottom of the filter tank and is used to drain the dirty water after flushing the filter component.

[0006] Preferably, the flushing mechanism includes: The diversion component is slidably arranged on the inner wall of the filter tank through a sliding member and is used to guide the flow of liquid; The sliding member includes a filter element slidably connected to the inner wall of the filter tank, and a first fixing sleeve is fixedly connected to the inner wall of the filter tank; The extrusion component is fixedly arranged on the outer wall of the water delivery pipe through a fixing member and is used to extrude the flushing fluid; The fixing member includes a sealing plate fixedly connected to the outer wall of the water delivery pipe, and a water injection pipe is connected through the inner wall of the sealing plate; Among them, part of the purified water is guided by the diversion component to flow to the top of the filter element, and the other part of the purified water is injected into the water collection frame. Then, through the extrusion component, the extrusion block descends to extrude the purified water at the bottom of the extrusion block, accelerating the flow rate of the purified water in the filter element and generating a stronger impact force on the impurities in the filter element.

[0007] Preferably, the turbulence mechanism includes: The perturbation component is fixedly arranged on the inner wall of the filter tank through a connecting member and is used to perturb the purified water; The connecting member includes five fixing frames fixedly connected to the inner wall of the filter tank, and arc-shaped rotating plates are rotatably connected to the outer walls of the five fixing frames; The water discharge component is fixedly arranged on the inner wall of the filter tank and is used to push the filter element to vibrate; Among them, the purified water impacted on the filter element is perturbed by the perturbation component to cause fluctuations in the purified water and strong purified water turbulence. When the extrusion block extrudes the purified water again, the purified water flows irregularly, enabling it to fully contact different positions of the filter element and better impact the impurities in the filter element. Then, the water discharge component causes the filter element to vibrate, prompting the impurities attached to the surface of the filter element to fall off, facilitating the flushing of the filter element.

[0008] Preferably, the filter component includes a flow dividing pipe connected through the outer walls of the two filter tanks, and two valve two are rotatably connected to the inner wall of the flow dividing pipe; The drainage component includes a drain pipe connected through the bottoms of the two filter tanks, and two valve three are rotatably connected to the inner wall of the drain pipe; Among them, tap water is input into the water inlet pipe, and the tap water enters the water delivery pipe through the water inlet pipe, causing the tap water to accumulate at the bottom of the filter tank. As the tap water continues to be injected, the tap water will rise to contact the filter element to filter the tap water until the filter tank is filled with tap water. The tap water located at the top of the filter element is the filtered purified water, and the purified water will enter the flow dividing pipe through the flow dividing plate, and the filtered purified water is discharged through the flow dividing pipe.

[0009] Preferably, the diversion assembly includes a diversion plate fixedly connected to the inner wall of the diversion pipe. A first spring return rod is slidably connected to the inner wall of the first fixing sleeve, and the bottom of the first spring return rod is fixedly connected to the top of the extrusion block. The inner wall of the extrusion block is slidably connected to the outer wall of the water delivery pipe, and the outer wall of the water delivery pipe is slidably connected to the inner wall of the filter element. Among them, when the filter element continuously filters and too much impurities accumulate in the filter element and it is necessary to wash the filter element. For example, when it is necessary to wash the filter element on the left side, the operator closes the first valve on the left side to allow tap water to enter the filter tank on the right side for filtering the tap water. The purified water after filtration will enter the filter tank on the left side through the diversion pipe to wash the filter element on the left side. Then, the third valve on the left side is opened to discharge the waste water after washing. During the washing process, since the filter element is blocked, the flow rate of the purified water in the filter element will be slowed down, and the drainage rate will be less than the water inlet rate. Therefore, the purified water at the top of the filter element will gradually fill the top of the filter element.

[0010] Preferably, the extrusion assembly includes five inclined panels fixedly connected to the bottom of the water collection frame. The inner wall of the water collection frame is rotatably connected to the outer wall of the sealing plate, and the outer wall of the water injection pipe is connected to the inner wall of the diversion plate in a penetrating manner.

[0011] Preferably, the extrusion assembly further includes a convex rod fixedly connected to the top of the extrusion block. The inner wall of the extrusion block is slidably connected to the outer wall of the water injection pipe. Among them, when the purified water enters the filter tank, part of the purified water will enter the water collection frame through the water injection pipe until the inside of the water collection frame is filled with purified water. The purified water in the water collection frame will be sprayed onto the inclined panels through the spray pipe. Since the size of the spray pipe is small, the purified water will generate a strong impact force to impact the inclined panels, causing the inclined panels to drive the water collection frame to rotate, so that the multiple inclined panels rotate synchronously. As the inclined panels continue to rotate, the inclined surface of the inclined panel will contact the top of the convex rod, squeezing the convex rod to descend, causing the extrusion block to descend, driving the first spring return rod to descend, so that it is squeezed and stores the resilience. When the extrusion block descends, it will squeeze the purified water at the bottom of the extrusion block, accelerating the flow rate of the purified water in the filter element, generating a stronger impact force on the impurities in the filter element, effectively peeling off the solid impurities on the surface of the filter element, and effectively preventing the purified water from flowing through multiple pipes, resulting in a decrease in the impact force of the purified water and affecting the washing of the filter element.

[0012] Preferably, the disturbance assembly includes five push rods fixedly connected to the bottom of the extrusion block. An arc-shaped sleeve is fixedly connected to the side wall of each of the five fixing frames. An arc-shaped spring rod is slidably connected to the inner wall of each of the five arc-shaped sleeves, and the side wall of each of the five arc-shaped spring rods is fixedly connected to the outer wall of each of the five arc-shaped rotating plates. Among them, when the extrusion block descends, it drives the push rod to descend, bringing the push rod into contact with the arc-shaped rotating plate, causing the arc-shaped rotating plate to rotate, driving the arc-shaped spring rod to rotate, and accumulating its resilience. When the extrusion block ascends and the push rod separates from the arc-shaped rotating plate, the resilience of the arc-shaped spring rod is released, causing the arc-shaped rotating plate to rotate back to its original position. The resilience of the arc-shaped spring rod causes the arc-shaped rotating plate to swing slightly, disturbing the purified water at the top of the filter element, enhancing the turbulence of the purified water. When the extrusion block squeezes the purified water again, the purified water flows irregularly, can fully contact different positions of the filter element, and better impacts the impurities in the filter element.

[0013] Preferably, the water discharge assembly includes nine water guide pipes connected through the inner wall of the filter tank. Six fixing sleeves II are fixedly connected to the bottom of the filter tank. The inner walls of the six fixing sleeves II are all slidably connected with spring return rods II. The tops of the six spring return rods II are in contact with the bottom of the filter element. Among them, when the extrusion block squeezes the purified water, the impact force of the purified water will increase. The increased impact force will push the filter element downward, squeezing the spring return rod II. When the extrusion block ascends, the resilience of the spring return rod II will be released, pushing the filter element upward, causing the filter element to vibrate slightly, prompting the impurities attached to the surface of the filter element to fall off, facilitating the flushing of the filter element. Additionally, when the water spray pipe sprays purified water, the purified water will fall on the top of the extrusion block. Since the top of the extrusion block is higher on the side close to the water delivery pipe and lower on the side far from the water delivery pipe, the purified water will move towards the water guide pipe, enabling the purified water to enter the water guide pipe and discharging the purified water on the top of the extrusion block, effectively preventing the accumulation of purified water on the top of the extrusion block, resulting in the water collection frame being immersed in the purified water. When the water spray pipe sprays water on the inclined panel, the purified water blocks the purified water sprayed from the water spray pipe, reducing the impact force of the purified water sprayed from the water spray pipe on the inclined panel and affecting the rotation of the water collection frame.

[0014] The present invention has the following beneficial effects: (1) When the present invention is in use, when it is necessary to flush the filter element, for example, when flushing the filter element on the left side, the purified water after filtration enters the left filter tank through the shunt pipe to flush the filter element. Then, open the valve III on the left side to discharge the wastewater after flushing. During the flushing process, part of the purified water is guided by the diversion assembly to flow to the top of the filter element, and the other part of the purified water is injected into the water collection frame. Then, through the extrusion assembly, the extrusion block descends to squeeze the purified water at the bottom of the extrusion block, accelerating the flow rate of the purified water in the filter element, generating a stronger impact force on the impurities in the filter element, effectively peeling off the solid impurities on the surface of the filter element, and effectively preventing the purified water from flowing through multiple pipes, resulting in a decrease in the impact force of the purified water and affecting the flushing of the filter element.

[0015] (2) After the inclined panel is separated from the convex rod in the present invention, the driving force on the convex rod disappears, and the resilience of the first spring reset rod is released, causing the extrusion block to rise until the inclined panel presses the convex rod again, making the extrusion block press the purified water again. This process repeats, causing the extrusion block to intermittently press the purified water. Since the impact force of the purified water increases instantaneously each time the extrusion block descends to press the purified water, the increased impact force each time impacts the impurity layer accumulated at the bottom of the filter element, effectively preventing the upper impurities from gradually accumulating downward when the filter element is flushed from top to bottom, resulting in the accumulation of impurities at the bottom of the filter element and making it difficult to fully remove them.

[0016] (3) When the extrusion block descends in the present invention, it drives the push rod to descend, causing the push rod to contact the arc-shaped rotating plate and rotate the arc-shaped rotating plate, driving the arc-shaped spring rod to rotate and accumulate resilience. When the extrusion block rises and the push rod separates from the arc-shaped rotating plate, the resilience of the arc-shaped spring rod is released, causing the arc-shaped rotating plate to rotate back to its original position. The slight swing of the arc-shaped rotating plate through the resilience of the arc-shaped spring rod disturbs the purified water at the top of the filter element, enhancing the turbulence of the purified water. When the extrusion block presses the purified water again, the purified water flows irregularly, enabling it to fully contact different positions of the filter element and better impact the impurities in the filter element.

[0017] (4) When the extrusion block presses the purified water in the present invention, the purified water impacts the filter element, causing the filter element to descend. Through the disturbance component, the filter element generates slight vibrations, prompting the impurities attached to the surface of the filter element to fall off, facilitating the flushing of the filter element. Additionally, when the water spray pipe sprays purified water, the purified water falls on the top of the extrusion block. Through the waterproof component, it effectively prevents the purified water from accumulating on the top of the extrusion block, resulting in the water collection frame being immersed in the purified water. When the water spray pipe sprays water on the inclined panel, the purified water blocks the purified water sprayed from the water spray pipe, reducing the impact force of the purified water sprayed from the water spray pipe on the inclined panel and affecting the rotation of the water collection frame.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] In the first embodiment, please refer to Figures 1 - 3 , the present invention is a parallel nanofiltration and ultrafiltration filter element water purifier, including two filter tanks 111. The parts contained inside the two filter tanks 111 are the same. The tops of the two filter tanks 111 are connected through a water inlet pipe 112, and two valves 113 are rotatably connected to the inner wall of the water inlet pipe 112; A shunt mechanism 1, the top of the shunt mechanism 1 is fixedly installed with a filter assembly 11, and the bottom of the shunt mechanism 1 is provided with a drainage assembly 12. The filter assembly 11 is used to filter tap water; A flushing mechanism 2, the flushing mechanism 2 is installed on the inner wall of the shunt mechanism 1 and is used to flush the filter assembly 11; and A turbulence mechanism 3, the turbulence mechanism 3 is located on the inner wall of the shunt mechanism 1 and is used to disturb the flushing liquid; A pressing block 214 is slidably connected to the inner wall of the filter tank 111, and a water delivery pipe 212 is connected through the inner wall of the filter tank 111. A water collecting frame 221 is rotatably connected to the outer wall of the water delivery pipe 212, and a water spraying pipe 225 is connected through the bottom of the water collecting frame 221; Among them, tap water is injected into the diversion mechanism 1, and the tap water is filtered by the filtration component 11. At the same time, when the filtration component 11 is dirty, the filtration component 11 is flushed by the flushing mechanism 2 to strip the solid impurities on the surface of the filter element 211, so that the filter element 211 is unblocked again, facilitating the filtration of tap water again. Then, the turbulent flow mechanism 3 disturbs the flushing liquid to enhance the liquid impact force.

[0023] The diversion mechanism 1 includes: A filtration component 11, which is fixedly arranged at the top of the filter tank 111 and is used for filtering tap water; A drainage component 12, which is fixedly arranged at the bottom of the filter tank 111 and is used for discharging the dirty water after flushing the filtration component 11.

[0024] The flushing mechanism 2 includes: A diversion component 21, which is slidably arranged on the inner wall of the filter tank 111 through a sliding member and is used for guiding the flow of liquid; The sliding member includes a filter element 211 slidably connected to the inner wall of the filter tank 111, and a first fixing sleeve 215 is fixedly connected to the inner wall of the filter tank 111; A pressing component 22, which is fixedly arranged on the outer wall of the water delivery pipe 212 through a fixing member and is used for pressing the flushing fluid; The fixing member includes a sealing plate 222 fixedly connected to the outer wall of the water delivery pipe 212, and a water injection pipe 223 is connected through the inner wall of the sealing plate 222; Among them, part of the purified water is guided by the diversion component 21 to flow to the top of the filter element 211, and the other part of the purified water is injected into the water collecting frame 221. Then, through the pressing component 22, the pressing block 214 is lowered to press the purified water at the bottom of the pressing block 214, accelerating the flow rate of the purified water in the filter element 211 and generating a stronger impact force on the impurities in the filter element 211.

[0025] The turbulent flow mechanism 3 includes: A disturbance component 31, which is fixedly arranged on the inner wall of the filter tank 111 through a connecting member and is used for disturbing the purified water; The connecting member includes five fixing frames 311 fixedly connected to the inner wall of the filter tank 111, and arc-shaped rotating plates 312 are rotatably connected to the outer walls of the five fixing frames 311; A water discharging component 32, which is fixedly arranged on the inner wall of the filter tank 111 and is used for pushing the filter element 211 to vibrate; Among them, the purified water impacted on the filter element 211 is disturbed by the disturbance component 31, causing the purified water to fluctuate and strong purified water turbulence. When the extrusion block 214 extrudes the purified water again, the purified water will flow irregularly, enabling it to fully contact different positions of the filter element 211, better impacting the impurities in the filter element 211. Then, the filter element 211 is vibrated through the water discharge component 32, prompting the impurities attached to the surface of the filter element 211 to fall off, facilitating the flushing of the filter element 211.

[0026] Embodiment 2. Please refer to Figures 1 - 8 , the present invention is a parallel nanofiltration and ultrafiltration filter element water purifier. On the basis of Example 1, the filtration component 11 includes a shunt pipe 114 connected through and at the outer walls of the two filter tanks 111, and two valves II 115 are rotatably connected to the inner wall of the shunt pipe 114; The drainage component 12 includes a drain pipe 121 connected through and at the bottoms of the two filter tanks 111, and two valves III 122 are rotatably connected to the inner wall of the drain pipe 121; Among them, by inputting tap water into the water inlet pipe 112, the tap water enters the water delivery pipe 212 through the water inlet pipe 112, causing the tap water to accumulate at the bottom of the filter tank 111. With the continuous injection of tap water, the tap water will rise and contact the filter element 211 to filter the tap water until the filter tank 111 is filled with tap water. The tap water at the top of the filter element 211 is the filtered purified water, and the purified water will enter the shunt pipe 114 through the shunt plate 213, and the filtered purified water is discharged through the shunt pipe 114.

[0027] The diversion component 21 includes a shunt plate 213 fixedly connected to the inner wall of the shunt pipe 114. A spring return rod I 216 is slidably connected to the inner wall of the fixed sleeve I 215, and the bottom of the spring return rod I 216 is fixedly connected to the top of the extrusion block 214; The inner wall of the extrusion block 214 is slidably connected to the outer wall of the water delivery pipe 212, and the outer wall of the water delivery pipe 212 is slidably connected to the inner wall of the filter element 211; Among them, when the filter element 211 continuously filters and too many impurities accumulate in the filter element 211 and the filter element 211 needs to be flushed. For example, when the filter element 211 on the left needs to be flushed, as Figure 2 shown, the operator closes the valve I 113 on the left, causing the tap water to enter the filter tank 111 on the right to filter the tap water. The filtered purified water will enter the filter tank 111 on the left through the shunt pipe 114 to flush the filter element 211 on the left. Then, the valve III 122 on the left is opened to discharge the flushed wastewater. During the flushing process, since the filter element 211 is blocked, the flow rate of the purified water in the filter element 211 will be slowed down, and the drainage rate will be less than the water inlet rate. Therefore, the purified water at the top of the filter element 211 will gradually fill the top of the filter element 211.

[0028] The extrusion assembly 22 includes five inclined panels 224 fixedly connected to the bottom of the water collection frame 221. The inner wall of the water collection frame 221 is rotatably connected to the outer wall of the plugging plate 222, and the outer wall of the water injection pipe 223 is connected to the inner wall of the flow distribution plate 213 in a penetrating manner.

[0029] The extrusion assembly 22 further includes a convex rod 226 fixedly connected to the top of the extrusion block 214. The inner wall of the extrusion block 214 is slidably connected to the outer wall of the water injection pipe 223; Among them, when the purified water enters the filter tank 111, part of the purified water will enter the water collection frame 221 through the water injection pipe 223 until the inside of the water collection frame 221 is filled with the purified water. The purified water in the water collection frame 221 will be sprayed against the inclined panel 224 through the water spray pipe 225. Since the size of the water spray pipe 225 is small, the purified water will generate a strong impact force, impact the inclined panel 224, cause the inclined panel 224 to drive the water collection frame 221 to rotate, and make the multiple inclined panels 224 rotate synchronously. As the inclined panel 224 continues to rotate, the inclined surface of the inclined panel 224 will contact the top of the convex rod 226, squeeze the convex rod 226 to descend, cause the extrusion block 214 to descend, drive the first spring return rod 216 to descend, make it be squeezed and accumulate the resilience force. When the extrusion block 214 descends, it will squeeze the purified water at the bottom of the extrusion block 214, accelerate the flow rate of the purified water in the filter element 211, generate a stronger impact force on the impurities in the filter element 211, effectively peel off the solid impurities on the surface of the filter element 211, and effectively prevent the purified water from flowing through multiple pipes, resulting in a decrease in the impact force of the purified water and affecting the flushing of the filter element 211.

[0030] The disturbance assembly 31 includes five push rods 313 fixedly connected to the bottom of the extrusion block 214. Arc-shaped sleeves 314 are fixedly connected to the side walls of the five fixed frames 311; Arc-shaped spring rods 315 are slidably connected to the inner walls of the five arc-shaped sleeves 314. The side walls of the five arc-shaped spring rods 315 are fixedly connected to the outer walls of the five arc-shaped rotating plates 312; Among them, when the extrusion block 214 descends, it will drive the push rod 313 to descend, make the push rod 313 contact the arc-shaped rotating plate 312, drive the arc-shaped rotating plate 312 to rotate, drive the arc-shaped spring rod 315 to rotate, and make it accumulate the resilience force. When the extrusion block 214 rises and the push rod 313 separates from the arc-shaped rotating plate 312, the resilience force of the arc-shaped spring rod 315 will be released, make the arc-shaped rotating plate 312 rotate back to its original position, and make the arc-shaped rotating plate 312 swing slightly through the resilience force of the arc-shaped spring rod 315, disturbing the purified water at the top of the filter element 211, enhancing the turbulence of the purified water, making the purified water flow irregularly when the extrusion block 214 squeezes the purified water again, being able to fully contact different positions of the filter element 211, and better impacting the impurities in the filter element 211.

[0031] The water discharge assembly 32 includes nine water guide pipes 321 connected through the inner wall of the filter tank 111. Six fixing sleeves two 322 are fixedly connected to the bottom of the filter tank 111. A spring return rod two 323 is slidably connected to the inner wall of each of the six fixing sleeves two 322. The tops of the six spring return rods two 323 are in contact with the bottom of the filter element 211. Among them, when the extrusion block 214 extrudes the purified water, the impact force of the purified water will increase. The increased impact force will push the filter element 211 downward, squeezing the spring return rod two 323. When the extrusion block 214 rises, the resilience of the spring return rod two 323 will be released, pushing the filter element 211 upward, causing the filter element 211 to vibrate slightly, prompting the impurities attached to the surface of the filter element 211 to fall off, facilitating the flushing of the filter element 211. Additionally, when the water spray pipe 225 sprays purified water, the purified water will fall on the top of the extrusion block 214. Since the top of the extrusion block 214 is higher on the side close to the water delivery pipe 212 and lower on the side far from the water delivery pipe 212, the purified water will move in the direction of the water guide pipe 321, enabling the purified water to enter the water guide pipe 321 and discharging the purified water on the top of the extrusion block 214, effectively preventing the purified water from accumulating on the top of the extrusion block 214 and causing the water collection frame 221 to be immersed in the purified water. When the water spray pipe 225 sprays water on the inclined panel 224, the purified water blocks the purified water sprayed from the water spray pipe 225, reducing the impact force of the purified water sprayed from the water spray pipe 225 on the inclined panel 224 and affecting the rotation of the water collection frame 221.

[0032] The quantity of the above components is not limited. Those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions. A specific application of this embodiment is as follows: When the present invention is in use, tap water is input into the water inlet pipe 112. Through the water inlet pipe 112, the tap water enters the water delivery pipe 212, causing the tap water to accumulate at the bottom of the filter tank 111. With the continuous injection of tap water, the tap water will rise and come into contact with the filter element 211 to filter the tap water until the filter tank 111 is filled with tap water. The tap water located at the top of the filter element 211 is the filtered purified water, and the purified water will enter the shunt pipe 114 through the shunt plate 213, and the filtered purified water is discharged through the shunt pipe 114. When the filter element 211 continuously filters and too much impurities accumulate in the filter element 211, it is necessary to flush the filter element 211. For example, when it is necessary to flush the filter element 211 on the left side, as Figure 2 shown, the operator closes the valve one 113 on the left side, enabling the tap water to enter the filter tank 111 on the right side to filter the tap water. The filtered purified water will enter the filter tank 111 on the left side through the shunt pipe 114 to flush the filter element 211 on the left side, and then the valve three 122 on the left side is opened to discharge the flushed wastewater. During the flushing process, since the filter element 211 is blocked, the flow rate of the purified water in the filter element 211 will be slowed down, causing the drainage rate to be less than the water inlet rate. Therefore, the purified water at the top of the filter element 211 will gradually fill the top of the filter element 211. At the same time, when the purified water enters the filter tank 111, part of the purified water will enter the water collection frame 221 through the water injection pipe 223 until the water collection frame 221 is filled with purified water. The purified water in the water collection frame 221 will be sprayed against the inclined panel 224 through the water spray pipe 225. Since the size of the water spray pipe 225 is small, the purified water will generate a strong impact force, impacting the inclined panel 224, causing the inclined panel 224 to drive the water collection frame 221 to rotate, enabling multiple inclined panels 224 to rotate synchronously. As the inclined panel 224 continues to rotate, the inclined surface of the inclined panel 224 will contact the top of the convex rod 226, squeezing the convex rod 226 to descend, causing the extrusion block 214 to descend, driving the first spring return rod 216 to descend, making it be squeezed and storing elastic resilience. When the extrusion block 214 descends, it will squeeze the purified water at the bottom of the extrusion block 214, accelerating the flow rate of the purified water in the filter element 211, generating a stronger impact force on the impurities in the filter element 211, effectively peeling off the solid impurities on the surface of the filter element 211, and effectively preventing the purified water from flowing through multiple pipes, resulting in a decrease in the impact force of the purified water and affecting the flushing of the filter element 211; Secondly, after the inclined panel 224 separates from the convex rod 226, the driving force on the convex rod 226 disappears, and the elastic resilience of the first spring return rod 216 will be released, causing the extrusion block 214 to rise until the inclined panel 224 squeezes the convex rod 226 again, making the extrusion block 214 squeeze the purified water again. This process repeats, causing the extrusion block 214 to intermittently squeeze the purified water. Since the impact force of the purified water will instantaneously increase each time the extrusion block 214 descends to squeeze the purified water, each increased impact force will impact the impurity layer accumulated at the bottom of the filter element 211, effectively preventing the upper-layer impurities from gradually accumulating downward when the filter element 211 is flushed from top to bottom, resulting in the accumulation of impurities at the bottom of the filter element 211 and being difficult to fully remove; Secondly, when the extrusion block 214 descends, it will drive the push rod 313 to descend, causing the push rod 313 to contact the arc-shaped rotating plate 312, driving the arc-shaped rotating plate 312 to rotate, driving the arc-shaped spring rod 315 to rotate, and storing elastic resilience. When the extrusion block 214 rises and the push rod 313 separates from the arc-shaped rotating plate 312, the elastic resilience of the arc-shaped spring rod 315 will be released, causing the arc-shaped rotating plate 312 to rotate back to its original position. The arc-shaped spring rod 315's elastic resilience causes the arc-shaped rotating plate 312 to slightly swing, disturbing the purified water at the top of the filter element 211, enhancing the turbulence of the purified water. When the extrusion block 214 squeezes the purified water again, the purified water will flow irregularly, being able to fully contact different positions of the filter element 211 and better impact the impurities in the filter element 211; Secondly, when the squeezing block 214 squeezes the purified water, the purified water will impact the filter element 211, causing the filter element 211 to descend and pressing the second spring return lever 323, enabling the second spring return lever 323 to accumulate resilience until the squeezing block 214 rises again and the impact force on the filter element 211 disappears. Then, the resilience of the second spring return lever 323 will be released, causing the filter element 211 to vibrate slightly, prompting the impurities attached to the surface of the filter element 211 to fall off, facilitating the flushing of the filter element 211. Additionally, when the water spraying pipe 225 sprays purified water, the purified water will fall on the top of the squeezing block 214. Since the side of the top of the squeezing block 214 close to the water delivery pipe 212 is higher and the side far from the water delivery pipe 212 is lower, the purified water will move towards the water guide pipe 321, enabling the purified water to enter the water guide pipe 321 and discharging the purified water on the top of the squeezing block 214, effectively preventing the accumulation of purified water on the top of the squeezing block 214, which may cause the water collection frame 221 to be immersed in the purified water. When the water spraying pipe 225 sprays water on the inclined panel 224, the purified water blocks the purified water sprayed from the water spraying pipe 225, reducing the impact force of the purified water sprayed from the water spraying pipe 225 on the inclined panel 224 and affecting the rotation of the water collection frame 221.
