Description

Technical Field

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

[0002] The design of the parallel dual ultrafiltration filter element can increase the clean water flow rate by connecting two PVDF ultrafiltration membranes in parallel. The parallel water purifier is a device that improves water purification efficiency and water quality by connecting multiple filtering devices in parallel. It consists of multiple independent filtering devices. The water source is connected to each filtering device through an integrated waterway plate, and the filtered water is converged and output. It can supply water at a large flow rate. It can also use the filtered clean water from the filter element at one end to backwash the filter element at the other end, realizing 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 often impacts the filter element of the water purifier to flush the filter element. However, purified water needs to pass through multiple pipes, which will cause the impact force of the purified water to decrease. It may lead to insufficient impact force, making it difficult to effectively remove pollutants on the surface of the filter element, affecting the backwashing effect. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a parallel nanofiltration and ultrafiltration filter element water purifier, comprising two filter tanks, the parts contained in the two filter tanks are the same, the tops of the two filter tanks are connected through a water inlet pipe, and the inner walls of the water inlet pipes are rotatably connected to two valves.

[0005] A diversion mechanism, a filter assembly is fixedly installed on the top of the diversion mechanism, and a drainage assembly is installed at the bottom of the diversion mechanism, and the filter assembly is used to filter tap water;

[0006] A flushing mechanism, which is installed on the inner wall of the diversion mechanism and is used to flush the filter assembly; and

[0007] A flow disturbing mechanism, located at the inner wall of the diverter mechanism and used for disturbing the flushing liquid;

[0008] The inner wall of the filter tank is slidably connected with an extrusion block, the inner wall of the filter tank is connected with a water pipe, the outer wall of the water pipe is rotatably connected with a water collecting frame, and the bottom of the water collecting frame is connected with a water spraying pipe;

[0009] Among them, tap water is injected into the diversion mechanism and filtered through the filter component. At the same time, when the filter component is dirty, the filter component is flushed through the flushing mechanism to peel off the solid impurities on the surface of the filter element, so that the filter element is unobstructed again, which is convenient for filtering the tap water again. The flushing liquid is then disturbed by the disturbing mechanism to enhance the impact force of the liquid.

[0010] Preferably, the diversion mechanism includes:

[0011] The filter assembly is fixedly arranged on the top of the filter tank and is used to filter tap water;

[0012] The drainage assembly is fixedly arranged at the bottom of the filter tank and is used to discharge the dirty water after flushing the filter assembly.

[0013] Preferably, the flushing mechanism comprises:

[0014] A flow guide assembly is slidably arranged on the inner wall of the filter tank through a sliding member to guide the flow of liquid;

[0015] The sliding member comprises a filter element slidably connected to the inner wall of the filter tank, and a fixing sleeve 1 is fixedly connected to the inner wall of the filter tank;

[0016] An extrusion assembly is fixedly arranged on the outer wall of the water pipe through a fixing member and is used for squeezing the flushing fluid;

[0017] The fixing member includes a blocking plate fixedly connected to the outer wall of the water delivery pipe, and the inner wall of the blocking plate is connected with a water injection pipe;

[0018] Among them, part of the clean water is guided to flow to the top of the filter element through the diversion component, and the other part of the clean water is injected into the water collecting frame. Then, the extrusion block is lowered through the extrusion component to squeeze the clean water at the bottom of the extrusion block, thereby accelerating the flow speed of the clean water in the filter element and generating a stronger impact on the impurities in the filter element.

[0019] Preferably, the spoiler mechanism comprises:

[0020] A disturbance component is fixedly arranged on the inner wall of the filter tank through a connecting piece and is used to disturb the purified water;

[0021] The connecting member comprises five fixing frames fixedly connected to the inner wall of the filter tank, and the outer walls of the five fixing frames are all rotatably connected to arc-shaped rotating plates;

[0022] The water discharge component is fixedly arranged on the inner wall of the filter tank and is used to drive the filter element to vibrate;

[0023] Among them, the disturbance component disturbs the clean water impacting the filter element, causing the clean water to fluctuate and increase the turbulence of the clean water. When the extrusion block squeezes the clean water again, the clean water will flow irregularly, which can fully contact different positions of the filter element and better impact the impurities in the filter element. The water discharge component then vibrates the filter element, causing the impurities attached to the surface of the filter element to fall off, making it easier to flush the filter element.

[0024] Preferably, the filter assembly includes a diverter pipe connected through the outer walls of the two filter tanks, and two valves 2 are rotatably connected to the inner wall of the diverter pipe;

[0025] The drainage assembly includes a drainage pipe connected to the bottom of the two filter tanks, and two valves are rotatably connected to the inner wall of the drainage pipe;

[0026] Among them, by inputting tap water into the water inlet pipe, the tap water enters the water delivery pipe through the water inlet pipe, so that the tap water accumulates at the bottom of the filter tank. As the tap water is continuously injected, the tap water will rise and contact the filter element, filtering the tap water until the filter tank is filled with tap water. The tap water at the top of the filter element is the filtered clean water. The clean water will enter the diversion pipe through the diversion plate, and the filtered clean water will be discharged through the diversion pipe.

[0027] Preferably, the flow guide assembly includes a diverter plate fixedly connected to the inner wall of the diverter pipe, a spring return rod 1 is slidably connected to the inner wall of the fixed sleeve 1, and the bottom of the spring return rod 1 is fixedly connected to the top of the extrusion block;

[0028] The inner wall of the extrusion block is slidably connected to the outer wall of the water pipe, and the outer wall of the water pipe is slidably connected to the inner wall of the filter element;

[0029] Among them, when the filter element continues to filter, too many impurities accumulate in the filter element and the filter element needs to be flushed. For example, when the filter element on the left needs to be flushed, the operator closes the valve one on the left to allow tap water to enter the filter tank on the right to filter the tap water. After the filtration is completed, the clean water will enter the filter tank on the left through the diversion pipe to flush the filter element on the left, and then the valve three on the left is opened to discharge the flushed waste water. During the flushing process, since the filter element is blocked, the flow rate of the clean water in the filter element will be slowed down, making the drainage rate less than the water inlet rate. Therefore, the clean water on the top of the filter element will gradually fill the top of the filter element.

[0030] Preferably, the extrusion assembly includes five inclined panels fixedly connected to the bottom of the water collecting frame, the inner wall of the water collecting frame is rotatably connected to the outer wall of the sealing plate, and the outer wall of the water injection pipe is through-connected to the inner wall of the diverter plate.

[0031] Preferably, the extrusion assembly further comprises a protruding rod fixedly connected to the top of the extrusion block, and the inner wall of the extrusion block is slidably connected to the outer wall of the water injection pipe;

[0032] Among them, when the clean water enters the filter tank, part of the clean water will enter the water collecting frame through the water injection pipe until the clean water fills the inside of the water collecting frame. The clean water in the water collecting frame will be sprayed toward the inclined plate through the water spray pipe. Due to the small size of the water spray pipe, the clean water will produce a strong impact force, impacting the inclined plate, causing the inclined plate to drive the water collecting frame to rotate, and causing multiple inclined plates to rotate synchronously. As the inclined plate continues to rotate, the inclined surface of the inclined plate will contact the top of the convex rod, squeezing the convex rod to drop, causing the squeezing block to drop, driving the spring return rod to drop, causing it to be squeezed and accumulate rebound force. When the squeezing block drops, it will squeeze the clean water at the bottom of the squeezing block, speeding up the flow rate of the clean water in the filter element, generating a stronger impact force on the impurities in the filter element, effectively stripping off the solid impurities on the surface of the filter element, and effectively preventing the clean water from flowing through multiple pipes, resulting in a decrease in the impact force of the clean water, affecting the flushing of the filter element.

[0033] Preferably, the disturbance assembly includes five push rods fixedly connected to the bottom of the extrusion block, and the side walls of the five fixing frames are fixedly connected with arc sleeves;

[0034] The inner walls of the five arc-shaped sleeves are all slidably connected with arc-shaped spring rods, and the side walls of the five arc-shaped spring rods are all fixedly connected with the outer walls of the five arc-shaped rotating plates;

[0035] Among them, when the extrusion block descends, it will drive the push rod to descend, allowing the push rod to contact the arc-shaped rotating plate, pushing the arc-shaped rotating plate to rotate, and driving the arc-shaped spring rod to rotate, so that it accumulates rebound force. When the extrusion block rises and separates the push rod from the arc-shaped rotating plate, the rebound force of the arc-shaped spring rod will be released, causing the arc-shaped rotating plate to rotate back to its position. The rebound force of the arc-shaped spring rod causes the arc-shaped rotating plate to swing slightly, disturbing the clean water at the top of the filter element and enhancing the turbulence of the clean water. When the extrusion block squeezes the clean water again, the clean water will produce irregular flow, which can fully contact different positions of the filter element and better impact the impurities in the filter element.

[0036] Preferably, the water discharge assembly includes nine water pipes connected to the inner wall of the filter tank, six fixed sleeves 2 are fixedly connected to the bottom of the filter tank, and the inner walls of the six fixed sleeves 2 are slidably connected to spring return rods 2, and the tops of the six spring return rods 2 are in contact with the bottom of the filter element;

[0037] Among them, when the extrusion block squeezes the clean water, the impact force of the clean water will increase, and the increased impact force will push the filter element down and squeeze the spring return rod 2. When the extrusion block rises, the rebound force of the spring return rod 2 will be released, pushing the filter element up, causing the filter element to vibrate slightly, prompting impurities attached to the surface of the filter element to fall off, and facilitating the flushing of the filter element; in addition: when the water spray pipe sprays clean water, the clean 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 pipe and lower on the side away from the water pipe, the clean water will move toward the water guide pipe, allowing the clean water to enter the water guide pipe and discharge the clean water on the top of the extrusion block, effectively preventing the clean water from accumulating on the top of the extrusion block, causing the water collecting frame to be immersed in the clean water. When the water spray pipe sprays water on the inclined plate, the clean water blocks the clean water sprayed from the water spray pipe, reducing the impact force of the clean water sprayed from the water spray pipe on the inclined plate, affecting the rotation of the water collecting frame.

[0038] The present invention has the following beneficial effects:

[0039] (1) When the present invention is used, when it is necessary to flush the filter element, such as when flushing the filter element on the left, the clean water after filtration is passed through the diversion pipe into the filter tank on the left to flush the filter element, and then the valve three on the left is opened to discharge the waste water after flushing. During the flushing process, part of the clean water is guided to flow to the top of the filter element through the guide component, and the other part of the clean water is injected into the water collection frame. Then, the extrusion block is lowered through the extrusion component to squeeze the clean water at the bottom of the extrusion block, thereby accelerating the flow rate of the clean water in the filter element, generating a stronger impact force on the impurities in the filter element, effectively stripping off the solid impurities on the surface of the filter element, and effectively preventing the clean water from flowing through multiple pipes, resulting in a decrease in the impact force of the clean water and affecting the flushing of the filter element.

[0040] (2) After the inclined plate and the protruding rod are separated, the pushing force on the protruding rod will disappear, and the rebound force of the spring return rod will be released, causing the extrusion block to rise until the inclined plate squeezes the protruding rod again, allowing the extrusion block to squeeze the clean water again, and so on, so that the extrusion block intermittently squeezes the clean water. Since the extrusion block will instantly increase the impact force of the clean water each time it descends to squeeze the clean water, each increased impact force will impact 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, causing the impurities to accumulate at the bottom of the filter element and difficult to fully remove.

[0041] (3) When the extrusion block of the present invention descends, it drives the push rod to descend, allowing the push rod to contact the arc-shaped rotating plate, pushing the arc-shaped rotating plate to rotate, driving the arc-shaped spring rod to rotate, so that it accumulates rebound force. When the extrusion block rises, causing the push rod to separate from the arc-shaped rotating plate, the rebound force of the arc-shaped spring rod will be released, causing the arc-shaped rotating plate to rotate back to its original position. The rebound force of the arc-shaped spring rod causes the arc-shaped rotating plate to swing slightly, disturbing the clean water at the top of the filter element, enhancing the turbulence of the clean water, and allowing the extrusion block to squeeze the clean water again, causing the clean water to produce irregular flow, which can fully contact different positions of the filter element and better impact the impurities in the filter element.

[0042] (4) In the present invention, when the extrusion block squeezes the clean water, the clean water will impact the filter element, causing the filter element to drop. Through the disturbance component, the filter element will generate slight vibration, prompting impurities attached to the surface of the filter element to fall off, making it easier to flush the filter element. In addition, when the water pipe sprays clean water, the clean water will fall on the top of the extrusion block. Through the waterproof component, the clean water is effectively prevented from accumulating on the top of the extrusion block, causing the water collecting frame to be immersed in the clean water. When the water pipe sprays water on the inclined plate, the clean water blocks the clean water sprayed from the water pipe, reducing the impact force of the clean water sprayed from the water pipe on the inclined plate, affecting the rotation of the water collecting frame.

DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] For example 1, please refer to Figure 1-Figure 3 The present invention is a parallel nanofiltration and ultrafiltration filter element water purifier, comprising two filter tanks 111. The two filter tanks 111 contain the same parts. The tops of the two filter tanks 111 are connected with water inlet pipes 112. The inner walls of the water inlet pipes 112 are rotatably connected with two valves 113.

[0056] A diversion mechanism 1, a filter assembly 11 is fixedly installed on the top of the diversion mechanism 1, and a drainage assembly 12 is installed at the bottom of the diversion mechanism 1. The filter assembly 11 is used to filter tap water;

[0057] A flushing mechanism 2 is installed on the inner wall of the diversion mechanism 1 and is used to flush the filter assembly 11; and

[0058] A flow disturbing mechanism 3, which is located on the inner wall of the diverter mechanism 1 and is used to disturb the flushing liquid;

[0059] The inner wall of the filter tank 111 is slidably connected to an extrusion block 214, the inner wall of the filter tank 111 is connected to a water pipe 212, the outer wall of the water pipe 212 is rotatably connected to a water collecting frame 221, and the bottom of the water collecting frame 221 is connected to a water spray pipe 225;

[0060] Among them, tap water is injected into the diversion mechanism 1 and filtered through the filter component 11. At the same time, when the filter component 11 is dirty, the filter component 11 is flushed by the flushing mechanism 2 to peel off the solid impurities on the surface of the filter element 211, so that the filter element 211 is unobstructed again, which is convenient for filtering the tap water again, and then the flushing liquid is disturbed by the disrupting mechanism 3 to enhance the impact force of the liquid.

[0061] The diversion mechanism 1 includes:

[0062] The filter assembly 11 is fixedly arranged on the top of the filter tank 111 and is used to filter tap water;

[0063] The drainage component 12 is fixedly arranged at the bottom of the filter tank 111 and is used to drain the dirty water after flushing the filter component 11.

[0064] Flushing mechanism 2 includes:

[0065] The flow guide component 21 is slidably disposed on the inner wall of the filter tank 111 through a sliding member, and is used to guide the flow of liquid;

[0066] The sliding member includes a filter element 211 slidably connected to the inner wall of the filter tank 111, and a fixing sleeve 215 is fixedly connected to the inner wall of the filter tank 111;

[0067] The extrusion assembly 22 is fixed to the outer wall of the water pipe 212 by a fixing member and is used to squeeze the flushing fluid;

[0068] The fixing member includes a blocking plate 222 fixedly connected to the outer wall of the water delivery pipe 212, and a water injection pipe 223 is connected to the inner wall of the blocking plate 222;

[0069] Among them, part of the clean water is guided to flow to the top of the filter element 211 through the guide component 21, and the other part of the clean water is injected into the water collecting frame 221. Then, through the extrusion component 22, the extrusion block 214 is lowered to squeeze the clean water at the bottom of the extrusion block 214, thereby accelerating the flow speed of the clean water in the filter element 211 and generating a stronger impact force on the impurities in the filter element 211.

[0070] The spoiler mechanism 3 includes:

[0071] A disturbance component 31 is fixedly mounted on the inner wall of the filter tank 111 through a connecting piece and is used to disturb the purified water;

[0072] The connecting member includes five fixing brackets 311 fixedly connected to the inner wall of the filter tank 111, and the outer walls of the five fixing brackets 311 are rotatably connected to arc-shaped rotating plates 312;

[0073] The water discharge component 32 is fixedly arranged on the inner wall of the filter tank 111 and is used to drive the filter element 211 to vibrate;

[0074] Among them, the disturbance component 31 disturbs the clean water impacting the filter element 211, causing the clean water to fluctuate and increase the turbulence of the clean water. When the extrusion block 214 squeezes the clean water again, the clean water will flow irregularly, which can fully contact different positions of the filter element 211 and better impact the impurities in the filter element 211. Then, the water discharge component 32 is used to vibrate the filter element 211, causing the impurities attached to the surface of the filter element 211 to fall off, thereby facilitating the flushing of the filter element 211.

[0075] For example 2, please refer to Figures 1-8 The present invention is a parallel nanofiltration and ultrafiltration filter element water purifier. Based on Example 1, the filter assembly 11 includes a diverter pipe 114 connected to the outer walls of two filter tanks 111, and two valves 115 are rotatably connected to the inner wall of the diverter pipe 114;

[0076] The drainage assembly 12 includes a drainage pipe 121 connected to the bottom of the two filter tanks 111, and two valves 122 are rotatably connected to the inner wall of the drainage pipe 121;

[0077] 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, so that the tap water accumulates at the bottom of the filter tank 111. As the tap water is continuously injected, the tap water will rise and contact the filter element 211, and the tap water will be filtered until the tap water fills the filter tank 111. The tap water at the top of the filter element 211 is the filtered clean water. The clean water will enter the diversion pipe 114 through the diversion plate 213, and the filtered clean water will be discharged through the diversion pipe 114.

[0078] The flow guide assembly 21 includes a diverter plate 213 fixedly connected to the inner wall of the diverter tube 114, a spring return rod 216 slidably connected to the inner wall of the fixed sleeve 215, and the bottom of the spring return rod 216 is fixedly connected to the top of the extrusion block 214;

[0079] The inner wall of the extrusion block 214 is slidably connected to the outer wall of the water pipe 212, and the outer wall of the water pipe 212 is slidably connected to the inner wall of the filter element 211;

[0080] When the filter element 211 continues to filter, there are too many impurities accumulated in the filter element 211, and the filter element 211 needs to be flushed. For example, when the filter element 211 on the left side needs to be flushed, Figure 2As shown, the operator closes the valve 113 on the left side to allow tap water to enter the filter tank 111 on the right side to filter the tap water. The clean water after filtering will enter the filter tank 111 on the left side through the diversion pipe 114 to flush the filter element 211 on the left side, and then the valve 3 122 on the left side is opened to discharge the flushed waste water. During the flushing process, since the filter element 211 is blocked, the flow rate of the clean water in the filter element 211 will be slowed down, making the drainage rate lower than the water inlet rate. Therefore, the clean water on the top of the filter element 211 will gradually fill the top of the filter element 211.

[0081] The extrusion assembly 22 includes five inclined panels 224 fixedly connected to the bottom of the water collecting frame 221. The inner wall of the water collecting frame 221 is rotatably connected to the outer wall of the blocking plate 222. The outer wall of the water injection pipe 223 is through-connected to the inner wall of the diverter plate 213.

[0082] The extrusion assembly 22 further includes a protruding rod 226 fixedly connected to the top of the extrusion block 214, and the inner wall of the extrusion block 214 is slidably connected to the outer wall of the water injection pipe 223;

[0083] When the clean water enters the filter tank 111, part of the clean water will enter the water collection frame 221 through the water injection pipe 223 until the clean water fills the inside of the water collection frame 221. The clean water in the water collection frame 221 will be sprayed toward the inclined plate 224 through the water spray pipe 225. Since the size of the water spray pipe 225 is small, the clean water will have a strong impact force, impacting the inclined plate 224, so that the inclined plate 224 drives the water collection frame 221 to rotate, so that the multiple inclined plates 224 rotate synchronously. As the inclined plate 224 continues to rotate, the inclined plate 224 will rotate synchronously. The inclined surface of 4 will contact the top of the protruding rod 226, squeezing the protruding rod 226 downward, causing the squeezing block 214 to descend, driving the spring return rod 216 to descend, causing it to be squeezed and accumulate rebound force. When the squeezing block 214 descends, it will squeeze the clean water at the bottom of the squeezing block 214, speeding up the flow rate of the clean water in the filter element 211, generating a stronger impact force on the impurities in the filter element 211, effectively stripping off the solid impurities on the surface of the filter element 211, and effectively preventing the clean water from flowing through multiple pipes, resulting in a decrease in the impact force of the clean water, which affects the flushing of the filter element 211.

[0084] The disturbance assembly 31 includes five push rods 313 fixedly connected to the bottom of the extrusion block 214, and the side walls of the five fixing frames 311 are fixedly connected to arc sleeves 314;

[0085] The inner walls of the five arc-shaped sleeves 314 are all slidably connected to arc-shaped spring rods 315, and the side walls of the five arc-shaped spring rods 315 are all fixedly connected to the outer walls of the five arc-shaped rotating plates 312;

[0086] When the squeeze block 214 descends, the push rod 313 will be driven down, so that the push rod 313 contacts the arc-shaped rotating plate 312, and the arc-shaped rotating plate 312 is pushed to rotate, driving the arc spring rod 315 to rotate, so that it accumulates a rebound force. When the squeeze block 214 rises and separates the push rod 313 from the arc-shaped rotating plate 312, the rebound force of the arc spring rod 315 will be released, so that the arc-shaped rotating plate 312 rotates back to its original position. The rebound force of the arc spring rod 315 causes the arc-shaped rotating plate 312 to swing slightly, disturbing the clean water at the top of the filter element 211 and enhancing the turbulence of the clean water. When the squeeze block 214 squeezes the clean water again, the clean water will produce an irregular flow, which can fully contact different positions of the filter element 211 and better impact the impurities in the filter element 211.

[0087] The drain assembly 32 includes nine water pipes 321 connected to the inner wall of the filter tank 111. Six fixing sleeves 322 are fixedly connected to the bottom of the filter tank 111. The inner walls of the six fixing sleeves 322 are all slidably connected to spring return rods 323. The tops of the six spring return rods 323 contact the bottom of the filter element 211.

[0088] When the squeezing block 214 squeezes the clean water, the impact force of the clean water will be enhanced. The enhanced impact force will push the filter element 211 down and squeeze the spring return rod 223. When the squeezing block 214 rises, the rebound force of the spring return rod 223 will be released, pushing the filter element 211 up, causing the filter element 211 to vibrate slightly, causing impurities attached to the surface of the filter element 211 to fall off, making it easier to flush the filter element 211. In addition, when the water spray pipe 225 sprays clean water, the clean water will fall on the top of the squeezing block 214. The side close to the water pipe 212 is high, and the side away from the water pipe 212 is low. Therefore, the clean water will move toward the water pipe 321, so that the clean water enters the water pipe 321, and the clean water on the top of the extrusion block 214 is discharged, effectively preventing the clean water from accumulating on the top of the extrusion block 214, causing the water collecting frame 221 to be immersed in the clean water. When the water spray pipe 225 sprays water on the inclined plate 224, the clean water blocks the clean water sprayed from the water spray pipe 225, reducing the impact force of the clean water sprayed from the water spray pipe 225 on the inclined plate 224, affecting the rotation of the water collecting frame 221.

[0089] There is no limit on the number of the above components. Those skilled in the art can freely set them according to actual needs. They only need to be installed in the corresponding component connection positions.

[0090] A specific application of this embodiment is as follows: when the present invention is used, tap water is input into the water inlet pipe 112, and the tap water is allowed to enter the water delivery pipe 212 through the water inlet pipe 112, so that the tap water accumulates at the bottom of the filter tank 111. As the tap water is continuously injected, the tap water rises and contacts the filter element 211, filtering 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 clean water, which enters the diverter pipe 114 through the diverter plate 213 and is discharged through the diverter pipe 114.

[0091] When the filter element 211 continues to filter, and impurities accumulate too much in the filter element 211, the filter element 211 needs to be flushed. For example, when the filter element 211 on the left side needs to be flushed, Figure 2 As shown, the operator closes the valve 113 on the left side to allow tap water to enter the filter tank 111 on the right side for filtration. The purified water after filtration enters the filter tank 111 on the left side through the diverter pipe 114 to flush the filter element 211 on the left side. The operator then opens the valve 122 on the left side to discharge the flushed waste water.

[0092] During the flushing process, since the filter element 211 is blocked, the flow rate of the clean water in the filter element 211 will be slowed down, making the drainage rate less than the water inlet rate. Therefore, the clean water on the top of the filter element 211 will gradually fill the top of the filter element 211. At the same time, when the clean water enters the filter tank 111, part of the clean water will enter the water collecting frame 221 through the water injection pipe 223 until the clean water fills the interior of the water collecting frame 221. The clean water in the water collecting frame 221 will be sprayed toward the inclined plate 224 through the water spray pipe 225. Since the size of the water spray pipe 225 is small, the clean water will generate a strong impact force to impact the inclined plate 224, causing the inclined plate 224 to drive the water collecting frame 221 to move. 1 rotates, causing multiple inclined plates 224 to rotate synchronously. As the inclined plates 224 continue to rotate, the inclined surfaces of the inclined plates 224 come into contact with the tops of the protruding rods 226, squeezing the protruding rods 226 downward, causing the squeezing block 214 to descend, driving the spring return rod 216 downward, squeezing it, accumulating rebound force, and the squeezing block 214 descends, squeezing the clean water at the bottom of the squeezing block 214, accelerating the flow rate of the clean water in the filter element 211, generating a stronger impact force on the impurities in the filter element 211, effectively stripping off the solid impurities on the surface of the filter element 211, and effectively preventing the clean water from flowing through multiple pipes, resulting in a decrease in the impact force of the clean water, affecting the flushing of the filter element 211;

[0093] Secondly, after the inclined plate 224 is separated from the protruding rod 226, the pushing force on the protruding rod 226 disappears, and the resilience of the spring return rod 216 is released, causing the squeezing block 214 to rise until the inclined plate 224 squeezes the protruding rod 226 again, allowing the squeezing block 214 to squeeze the clean water again, and so on and so forth, so that the squeezing block 214 squeezes the clean water intermittently. Since the squeezing block 214 squeezes the clean water each time it descends, the impact force of the clean water increases instantly, and each increased impact force impacts the impurity layer accumulated at the bottom of the filter element 211, effectively preventing the upper layer of impurities from gradually accumulating downwards when the filter element 211 is flushed from top to bottom, causing the impurities to accumulate at the bottom of the filter element 211 and be difficult to fully remove;

[0094] When the squeeze block 214 is lowered, the push rod 313 is driven to lower, so that the push rod 313 contacts the curved rotating plate 312, and the curved rotating plate 312 is pushed to rotate, which drives the curved spring rod 315 to rotate and accumulates a rebound force. When the squeeze block 214 is raised, so that the push rod 313 is separated from the curved rotating plate 312, the rebound force of the curved spring rod 315 is released, so that the curved rotating plate 312 rotates back to its original position. The rebound force of the curved spring rod 315 causes the curved rotating plate 312 to swing slightly, disturbing the clean water at the top of the filter element 211 and enhancing the turbulence of the clean water. When the squeeze block 214 squeezes the clean water again, the clean water produces an irregular flow, which can fully contact different positions of the filter element 211 and better impact the impurities in the filter element 211.

[0095] Secondly, when the squeezing block 214 squeezes the clean water, the clean water will impact the filter element 211, causing the filter element 211 to fall, squeezing the spring return rod 223, allowing the spring return rod 223 to accumulate rebound force until the squeezing block 214 rises again, the impact force on the filter element 211 disappears, and the rebound force of the spring return rod 223 is released, causing the filter element 211 to vibrate slightly, causing impurities attached to the surface of the filter element 211 to fall off, making it easier to flush the filter element 211; In addition: when the water spray pipe 225 sprays clean water, the clean water will fall on the top of the squeezing block 214. The top of the extrusion block 214 is higher on the side close to the water pipe 212 and lower on the side away from the water pipe 212. Therefore, the clean water will move toward the water pipe 321, allowing the clean water to enter the water pipe 321 and discharge the clean water on the top of the extrusion block 214, effectively preventing the clean water from accumulating on the top of the extrusion block 214, causing the water collecting frame 221 to be immersed in the clean water. When the water spray pipe 225 sprays water on the inclined plate 224, the clean water blocks the clean water sprayed from the water spray pipe 225, reducing the impact force of the clean water sprayed from the water spray pipe 225 on the inclined plate 224, affecting the rotation of the water collecting frame 221.
