Description

Technical Field

[0001] This invention relates to the technical field of water softening treatment, and more specifically to a water softening treatment device. Background Art

[0002] Water softening is a water treatment technology that removes hardness ions such as calcium and magnesium from water to reduce water hardness and prevent scale formation. Water softening relies on the ion exchange function of resin to remove calcium and magnesium ions and requires automated operation with the help of controllers, resin tanks, and brine tanks. Furthermore, the resin needs periodic salt regeneration to maintain its softening capacity.

[0003] Patent document CN117185418B discloses an integrated water softening device, comprising a salt tank, a resin tank, and a multi-way valve. A first partition is fixedly installed on the inner wall of the salt tank, dividing it into a salt storage chamber and a melting chamber. A second partition is fixedly installed in the melting chamber, dividing it into a purified water chamber and a brine chamber. An outlet is provided on the first partition, and a sealing plate slides on it. A limiting block for limiting the sealing plate also slides on the first partition. A first driving assembly is provided in the purified water chamber. A purified water pipe is provided between the multi-way valve and the purified water chamber. A reaction tank slides within the brine chamber, and a pump body is installed inside the reaction tank. A salt suction pipe is provided between the pump body and the multi-way valve. An outlet is provided on the second partition. A control component for driving the movement of the sealing plate is also provided in the salt tank. By controlling the amount of salt melting, salt crystallization at the bottom of the reaction tank is reduced.

[0004] However, this solution also has the following problems: When using a resin softening tank to treat hard water, impurities carried in the hard water adhere to the resin surface, causing surface blockage. For example, suspended solids and colloids in the water cover the resin particles, forming a dense contamination layer. This increases water flow resistance and clogs the resin micropores, leading to uneven water distribution and channeling within the resin. This prevents some resin from contacting the hard water, resulting in a poorer softening effect and reduced softening efficiency. If backwashing is used to clean the resin in this situation, frequent backwashing is required because only the surface is blocked, severely impacting work efficiency. Furthermore, insufficient backwashing over a long period can cause the resin surface to clump together, further restricting water flow and affecting the treatment effect. Summary of the Invention

[0005] This invention provides a water softening device, which aims to solve the problem in related technologies where impurities adhering to the surface of the resin lead to insufficient contact between the resin and hard water, thus affecting the treatment efficiency.

[0006] The water softening device of the present invention includes a tank body, and a filling cylinder filled with resin is provided inside the tank body. The filling cylinder includes: a fixed part fixedly connected to the tank body, and a sliding part located above the fixed part and slidingly engaged with the fixed part. The outer side of the sliding part is spaced apart from the inner wall of the tank body to form a collection cavity. An adjustment component and a cleaning component are provided inside the tank body. The adjustment component cooperates with the sliding part to drive it to move up and down. The cleaning component includes a pressure plate, a scraper, and a control component. The pressure plate is located above the sliding part, and the scraper is located below the pressure plate. The pressure plate has multiple through holes for water supply. The control component is connected to the scraper and the pressure plate respectively to drive the pressure plate to move up and down and the scraper to rotate.

[0007] The blockage layer on the upper surface of the resin is located between the pressure plate and the resin. The adjusting component drives the sliding part to move downward so that the upper end of the sliding part is lower than the blockage layer of the resin. The control component drives the scraper to rotate and scrape the blockage layer into the collection chamber. Then, it drives the pressure plate to move downward again to cooperate with the upper end of the sliding part.

[0008] Hard water enters from the top of the tank, passes through the filling cylinder, and finally exits from the bottom of the tank. The hard water is softened by the resin inside the filling cylinder. Impurities in the hard water remain on the surface of the resin, below the pressure plate. When there are many impurities, a blockage layer forms on the surface of the resin. When the blockage layer needs to be cleaned, the adjusting component moves the sliding part downward, so that the upper end of the sliding part is below the blockage layer. At the same time, the pressure plate separates from the sliding part. At this time, the pressure plate comes into contact with the upper surface of the resin, i.e., the blockage layer. The control component drives the scraper to rotate, scraping the blockage layer and some resin into the collection chamber. At this time, the blockage layer below the pressure plate is removed. Then the control component moves the pressure plate downward again to cooperate with the sliding part. This process is repeated to continuously clean the blockage layer on the upper surface of the resin, ensuring full contact between the hard water and the resin, reducing the frequency of resin regeneration, and improving softening efficiency.

[0009] Preferably, the control component includes: a control rod, a drive component one, a connecting ring, and an intermediate component. The control rod is rotatably mounted inside the tank. The drive component one is mounted on the tank. The output end of the drive component one is connected to the control rod to drive the control rod to rotate. The connecting ring is slidably mounted on the control rod and rotates with the pressure plate. The pressure plate is slidably mounted inside the tank. The pressure plate is connected to the control rod through the intermediate component. When the control rod rotates, it drives the pressure plate to move up and down, and at the same time, it drives the scraper to rotate synchronously through the connecting ring.

[0010] The drive unit drives the control lever to rotate, and the control lever drives the scraper to rotate synchronously through the connecting ring, scraping off the blockage layer on the upper surface of the resin. Then, the intermediate part drives the pressure plate to move downward, so that after the blockage layer is cleaned, the pressure plate engages with the sliding part again.

[0011] Preferably, the intermediate component includes: an intermediate ring sleeved on the outside of the control rod, and a spring component 1 disposed between the intermediate ring and the pressure plate. The intermediate ring is disposed on the side of the pressure plate away from the scraper. A threaded groove is provided on the control rod. The intermediate ring is threadedly engaged with the threaded groove 1. The rotation of the control rod drives the intermediate ring to move up and down. The intermediate ring drives the pressure plate to move up and down through the spring component 1.

[0012] When the control lever moves the scraper to clean the blockage layer, it moves the intermediate ring downwards in sync. However, at this time, the scraper does not remove the blockage layer. The pressure plate remains in contact with the blockage layer below, and the intermediate ring moves relative to the pressure plate. At the same time, it compresses the first spring. After the blockage layer is removed, the first spring moves the pressure plate downwards to cooperate with the sliding part.

[0013] Preferably, the adjustment assembly includes: a second driving component, a screw, and an adjusting ring. The second driving component is disposed inside the tank, and its output end is connected to the screw. The adjusting ring is slidably mounted inside the tank. The screw and the adjusting ring are threadedly engaged, and the adjusting ring is sleeved outside the sliding part. A first retaining ring is provided at the bottom of the adjusting ring, which is slidably engaged with the outer side of the sliding part. A second retaining ring is provided on the outer side of the sliding part, located below the first retaining ring. An elastic telescopic rod is provided below the sliding part, and the elastic telescopic rod is connected to the tank to drive the sliding part to move upward.

[0014] The second driving component drives the adjusting ring to move downward via a screw. The downward movement of the adjusting ring causes the first retaining ring to come into contact with the second retaining ring, which in turn causes the sliding part to move downward. Each time the blockage layer needs to be cleaned, the sliding part is moved downward a certain distance, and then the above operation is repeated.

[0015] Preferably, a backflushing assembly is provided on one side of the tank body. The backflushing assembly includes a salt tank, an inlet pipe, and an outlet pipe. Both the inlet pipe and the outlet pipe are connected to the salt tank. An installation ring is provided inside the tank body, located above the sliding part. The inlet pipe is connected to the bottom of the fixed part. The outlet pipe passes through the tank body and is connected to the inside of the installation ring. A hard water pipe for introducing hard water is provided on the tank body, with the outlet end of the hard water pipe located above the installation ring.

[0016] The brine enters the tank and flows upward from the bottom, passing through the resin to regenerate it before finally being discharged through the outlet pipe.

[0017] Preferably, an auxiliary plate is slidably installed inside the fixed part, and multiple auxiliary holes for water supply are opened on the auxiliary plate. A threaded groove is opened on the control rod, and the control rod is threadedly engaged with the auxiliary plate through the threaded groove.

[0018] The control lever rotates in the opposite direction, causing the auxiliary plate to move upward, relieving the pressure applied to the resin in the fixed part, causing the resin to rebound and increasing the gap between the resins. When the brine backflushes the resin, it allows the brine to come into full contact with the resin, improving the regeneration effect of the resin.

[0019] Preferably, the outer side of the control rod is coaxially provided with an annular groove 1 that communicates with thread groove 1 and an annular groove 2 that communicates with thread groove 2. The annular groove 1 is located at the upper end of thread groove 1, and there are two annular grooves 2 at both ends of thread groove 2.

[0020] The intermediate ring stops moving when it reaches one point of the annular groove, and the auxiliary plate stops moving when it reaches the second point of the annular groove. This ensures that when the control lever moves the pressure plate downward, the auxiliary plate is positioned at the second point of the annular groove, at which point the auxiliary plate remains stationary, reducing interference between the pressure plate and the auxiliary plate.

[0021] Preferably, an auxiliary sleeve is provided inside the auxiliary plate, which is fitted outside the control rod. A second spring and a connecting plate are provided inside the auxiliary sleeve. The connecting plate is slidably assembled inside the auxiliary sleeve. The connecting plate cooperates with the second threaded groove. The second spring is connected to the connecting plate and the auxiliary sleeve respectively. The second spring is used to drive the connecting plate to move upward.

[0022] When the control lever moves the pressure plate downward, the connecting plate always engages with the second annular groove. When the control lever rotates in the opposite direction, the second spring moves the connecting plate upward and engages with the second threaded groove. At this time, the control lever can drive the auxiliary plate to rotate in the opposite direction. After the auxiliary plate moves a certain distance, the connecting plate engages with another second annular groove, and the auxiliary plate stops moving. At this time, the auxiliary plate is completed.

[0023] Preferably, a guide slope is provided above the retaining ring, and the side of the guide slope near the sliding part is inclined downward.

[0024] During backflushing, the adjusting ring moves upward, causing the resin in the collection frame to re-enter the sliding part. At the same time, the direction in which the resin enters the sliding part is opposite to the direction of the backflushing water flow, which improves the rinsing effect on the resin and can also flush out impurities contained in the resin and discharge them outside the tank.

[0025] Preferably, the control lever is fitted with a mounting sleeve that slides up and down on its outer side, and the middle ring is fitted with a mounting sleeve that slides up and down on its inner side. The lower end of the mounting sleeve is fixedly connected to the pressure plate. Multiple support rods are provided on the outer circumference of the mounting sleeve, and a support slide rail is provided inside the mounting ring. The end of the support rod away from the mounting sleeve slides in cooperation with the support slide rail.

[0026] The support rod works in conjunction with the support slide rail to support the mounting sleeve. At the same time, the mounting sleeve is fixedly connected to the pressure plate, thereby improving the stability of the pressure plate when it moves up and down.

[0027] Beneficial effects:

[0028] This invention features a sliding part that slides into a fixed part, and a pressure plate and a scraper are mounted on the sliding part. When it is necessary to clean the blockage layer on the resin surface, the adjusting frame moves the sliding part downwards, so that the upper end of the sliding part is lower than the blockage layer. Then, the scraper scrapes the blockage layer into the collection chamber, and the pressure plate moves down again to engage with the sliding part, completing one cleaning of the blockage layer. This process can be repeated to clean the blockage layer on the resin surface multiple times, reducing the frequency of resin regeneration and increasing the contact area between hard water and resin, thereby improving softening efficiency.

Detailed Implementation

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 9 As shown, the water softening device of the present invention includes a tank 1 and a backflushing assembly 2 disposed on one side of the tank 1. The tank 1 contains a filling cylinder 3, an adjusting assembly 4, and a cleaning assembly 5. The filling cylinder 3 is filled with resin for softening hard water. The filling cylinder 3 includes a fixed part 31 and a sliding part 32. The fixed part 31 is fixedly connected to the tank 1, and the sliding part 32 slides vertically with the fixed part 31, with the sliding part 32 disposed at the upper end of the fixed part 31. The adjusting assembly 4 cooperates with the sliding part 32 to adjust the position of the sliding part 32. The cleaning assembly 5 is used to clean the blockage layer on the resin surface.

[0042] The sliding part 32 is arranged at intervals with the inner wall of the tank 1, and a collection cavity 11 for collecting blockages is formed between the sliding part 32 and the tank 1.

[0043] When treating hard water, the hard water passes sequentially through the resin in the sliding part 32 and the fixed part 31 for softening. Impurities in the hard water concentrate on the upper surface of the resin, forming a blockage layer, which is located near the upper end of the sliding part 32. When it is necessary to clean the blockage layer, the adjusting component 4 moves the sliding part 32 downward, so that the upper end of the sliding part 32 is below the resin blockage layer. Then, the cleaning component 5 cleans the blockage layer and moves it into the collection frame to eliminate the impact of the blockage on the upper surface of the resin and improve the softening efficiency. The above operation can be repeated to clean the blockage layer on the resin surface multiple times. After a period of use, the resin is regenerated by the backflushing component 2 to maintain the resin's softening ability.

[0044] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 The cleaning component 5 includes a pressure plate 51, a scraper 52, and a control component 53. The pressure plate 51 is located at the upper end of the sliding part 32 and contacts the upper surface of the resin. The scraper 52 is located below the pressure plate 51. Multiple through holes are evenly distributed on the pressure plate 51 to allow hard water to pass through. The control component 53 is connected to the pressure plate 51 and the scraper 52. The control component 53 drives the pressure plate 51 to move up and down and drives the scraper 52 to rotate. The rotation axis of the scraper 52 is on the same straight line as the center of the sliding part 32.

[0045] In this embodiment, the through hole on the pressure plate 51 has a large diameter, so it will not filter impurities in the hard water and will not affect the flow of hard water. It only allows hard water to pass through. After passing through the through hole, the hard water comes into contact with the resin. The blockage layer on the resin is located between the pressure plate 51 and the resin, that is, below the pressure plate 51.

[0046] Reference Figure 5 , Figure 6 When it is necessary to clean the blockage layer, the sliding part 32 moves so that its upper end is below the blockage layer. At this time, the pressure plate 51 separates from the sliding part 32, and then the control component 53 drives the scraper 52 to rotate, scraping away the blockage layer and the upper surface of the resin, thus cleaning the blockage layer. After cleaning, the pressure plate 51 is moved downward, so that the pressure plate 51 is once again above the sliding part 32, pressing the resin. This process is repeated to clean the blockage layer on the resin surface, ensuring that the hard water and resin are in full contact.

[0047] Reference Figure 3 , Figure 5 , Figure 6 The control component 53 includes: a control rod 531, a drive component 532, a connecting ring 533, and an intermediate component 534. The control rod 531 is arranged vertically and is rotatably mounted inside the tank body 1. The center of the control rod 531 and the center of the sliding part 32 are on the same straight line. The drive component 532 is a motor, and the output end of the drive component 532 is connected to the control rod 531 to drive the control rod 531 to rotate. The connecting ring 533 is sleeved on the outside of the control rod 531 and is slidably mounted on the control rod 531. A groove 6 is provided on the control rod 531 in the vertical direction. The connecting ring 533 is slidably engaged with the groove 6, that is, the connecting ring 533 is slidably engaged with the control rod 531 through the groove 6. The scraper 52 is connected to the side of the connecting ring 533, and multiple scrapers 52 are arranged around the connecting ring 533. The pressure plate 51 is slidably mounted inside the tank body 1. The intermediate part 534 is located between the pressure plate 51 and the control rod 531, and the pressure plate 51 is connected to the control rod 531 through the intermediate part 534.

[0048] The driving component 532 drives the control rod 531 to rotate, and the rotation of the control rod 531 drives the connecting ring 533 to rotate synchronously, which in turn drives the scraper 52 to rotate synchronously, so as to scrape off the blockage layer on the upper surface of the resin. After the blockage layer is scraped off, the intermediate component 534 drives the pressure plate 51 to move downward, so that the pressure plate 51 engages with the sliding part 32 again.

[0049] Reference Figure 6 The intermediate component 534 includes an intermediate ring 535 and a spring 536. The intermediate ring 535 is slidably sleeved on the outside of the control rod 531. The spring 536 is a spring. The intermediate ring 535 is located above the pressure plate 51, and the spring 536 is located between the intermediate ring 535 and the pressure plate 51. The spring 536 is connected to both the pressure plate 51 and the intermediate ring 535. A threaded groove 61 is provided on the outer circumference of the control rod 531. The threaded groove 61 is arranged vertically. The intermediate ring 535 is threadedly engaged with the threaded groove 61, so that the intermediate ring 535 can move up and down when the control rod 531 rotates.

[0050] After the sliding part 32 moves downward, the pressure plate 51 remains in contact with the upper surface of the resin. When the control rod 531 drives the scraper 52 to rotate, the pressure plate 51 remains stationary under the action of the resin. At the same time, the intermediate ring 535 moves downward and approaches the pressure plate 51, while the compression spring 536 applies a downward force to the pressure plate 51. After the scraper 52 scrapes off the upper surface of the resin, the spring 536 drives the pressure plate 51 to move downward so that the pressure plate 51 moves again to engage with the sliding part 32.

[0051] Reference Figure 6 The connecting ring 533 is rotatably engaged with the pressure plate 51. That is, the connecting ring 533 can rotate with the control rod 531 below the pressure plate 51, or it can move up and down with the pressure plate 51. When the pressure plate 51 moves down, it drives the scraper 52 to move synchronously, so as to clean the blockage layer on the resin surface again.

[0052] Reference Figure 2 , Figure 3 An installation ring 7 is provided inside the tank body 1. The installation ring 7 is located above the sliding part 32. A support slide rail 71 is provided inside the installation ring 7. The support slide rail 71 is arranged in the vertical direction.

[0053] Reference Figure 2 , Figure 3 , Figure 6 A mounting sleeve 72 is slidably mounted on the outside of the control lever 531. An intermediate ring 535 is slidably mounted inside the mounting sleeve 72. The mounting sleeve 72 is positioned above the pressure plate 51, and its lower end is fixedly connected to the pressure plate 51. Multiple support rods 73 are arranged circumferentially on the outside of the mounting sleeve 72. The end of each support rod 73 facing away from the mounting sleeve 72 is slidably engaged with a support rail 71.

[0054] By cooperating with the support rail 71 and the support rod 73, the pressure plate 51 is supported, so that the pressure plate 51 can only slide up and down inside the tank body 1, thereby improving the stability of the pressure plate 51 when it moves.

[0055] Reference Figure 2 , Figure 3 , Figure 5 The adjusting assembly 4 includes: a second driving component 41, a screw 42, and an adjusting ring 43. The second driving component 41 is disposed inside the tank body 1, and its output end is connected to the screw 42. The second driving component 41 is configured as a motor. The screw 42 is arranged parallel to the center line of the tank body 1. The adjusting ring 43 is slidably assembled inside the tank body 1, located within the collection chamber 11, and its outer side slides against the inner side of the tank body 1. The screw 42 passes through the adjusting ring 43 and is threadedly engaged with it.

[0056] Reference Figure 5 A retaining ring 431 is provided at the bottom of the adjusting ring 43. The retaining ring 431 is located inside the adjusting ring 43 and slides against the outer side of the sliding part 32. A retaining ring 321 is provided on the outer side of the sliding part 32, positioned below the retaining ring 431. The sliding part 32 is sleeved on the outside of the fixed part 31. An assembly ring 322 is provided at the lower end of the sliding part 32, located below the retaining ring 321. An elastic telescopic rod 323 is provided at the bottom of the assembly ring 322. The elastic telescopic rod 323 consists of two tubes of different diameters that slide against each other, and a spring is installed inside. The bottom of the elastic telescopic rod 323 is fixedly connected to the tank body 1, and the elastic telescopic rod 323 is used to drive the sliding part 32 to move upward.

[0057] Driven component 41 rotates screw 42, which in turn moves adjusting ring 43 downwards. Adjusting ring 43 engages retaining ring 431 and baffle 2, which in turn moves sliding part 32 downwards via retaining ring 321, thus adjusting the position of sliding part 32. As softening water continues to flow, sliding part 32 moves downwards each time the blockage layer needs to be cleared, and is fixed in its corresponding position after each cleaning. An elastic telescopic rod 323 is also provided. During backflushing, drive component 41 moves adjusting ring 43 upwards, and elastic telescopic rod 323 moves sliding part 32 upwards to its initial position, allowing the rinsed resin to re-enter sliding part 32.

[0058] Reference Figure 1The backflushing assembly 2 includes: a salt tank 21 containing brine, an inlet pipe 22 and an outlet pipe 23 installed on the salt tank 21. Both the inlet pipe 22 and the outlet pipe 23 are connected to the salt tank 21. Correspondingly, a water pump is installed on the salt tank 21, and the water pump is connected to the inlet pipe 22 and the outlet pipe 23 to introduce brine into the tank body 1 and extract it. The inlet pipe 22 is connected to the bottom of the tank body 1, and the outlet pipe 23 passes through the tank body 1 and is connected to the inside of the mounting ring 7.

[0059] Reference Figure 1 , Figure 2 , Figure 3 A hard water pipe 8 is installed on the tank body 1. The outlet end of the hard water pipe 8 passes through the tank body 1 and is positioned above the mounting ring 7. Multiple nozzles 81 are installed at the outlet end of the hard water pipe 8, and the multiple nozzles 81 are evenly distributed above the mounting ring 7 to spray hard water evenly onto the resin. The outlet end of the hard water pipe 8 is positioned above the outlet pipe 23.

[0060] When backflushing of the resin is required, the brine in the salt tank 21 is introduced into the tank body 1 through the inlet pipe 22. The brine flows upward through the bottom of the tank body 1, regenerates the resin, and is finally discharged through the outlet pipe 23.

[0061] An auxiliary plate 9 is slidably mounted up and down within the fixed part 31. The outer side of the auxiliary plate 9 slides against the inner side of the fixed part 31. The auxiliary plate 9 is positioned near the top of the fixed part 31 and has multiple auxiliary holes. These auxiliary holes serve the same function as through holes, allowing hard water to pass through. A threaded groove 62 is provided on the control rod 531, which is threadedly engaged with the auxiliary plate 9 via the threaded groove 62. This allows the position of the auxiliary plate 9 to be adjusted when the control rod 531 rotates.

[0062] Reference Figure 2 , Figure 3 , Figure 4 The auxiliary plate 9 presses the resin in the fixed part 31, and the pressure plate 51 presses the resin in the sliding part 32. During backflushing, the control lever 531 rotates, causing the pressure plate 51 to move upward and separate from the sliding part 32, and causing the auxiliary plate 9 to move upward, relieving the pressure on the resin in the fixed part 31. This results in the resin in both the fixed part 31 and the sliding part 32 being in a loose state, increasing the gap between the resins. This allows for a larger contact area between the brine and the resin during backflushing, ensuring sufficient contact between the brine and the resin and improving the regeneration effect of the resin.

[0063] Reference Figure 7 , Figure 8 , Figure 9An annular groove 63 and an annular groove 64 are coaxially formed on the outer side of the control rod 531. The annular groove 63 is connected to the threaded groove 61, and the annular groove 64 is connected to the threaded groove 62. The annular groove 63 is located at the upper end of the threaded groove 61. There are two annular grooves 64, and the two annular grooves 64 are located at the upper and lower ends of the threaded groove 62, respectively.

[0064] When the control lever 531 rotates, the intermediate ring 535 moves up and down under the action of the first thread groove 61, and the auxiliary plate 9 moves up and down under the action of the second thread groove 62. When the intermediate ring 535 moves to the first annular groove 63, the intermediate ring 535 engages with the first annular groove 63. At this time, the control lever 531 rotates the intermediate ring 535 to stop moving. When the auxiliary plate 9 moves to the second thread groove 62, the control lever 531 continues to rotate the auxiliary plate 9 to stop moving.

[0065] Initially, the auxiliary plate 9 engages with the annular groove 64 below the threaded groove 62. When the control lever 531 rotates, causing the intermediate ring 535 to move downwards and the sliding part 32 to move downwards, the auxiliary plate 9 remains stationary, maintaining pressure on the resin within the fixed part 31. When backflushing the resin, the control lever 531 rotates in the opposite direction, causing the sliding part 32 to move upwards. Simultaneously, the auxiliary plate 9 moves to engage with the threaded groove 62, causing it to move upwards as well. After moving a certain distance, the auxiliary plate 9 engages with the annular groove 64 at the upper end of the threaded groove 62, and the auxiliary plate 9 stops moving. When the intermediate ring 535 moves to the annular groove 63, the pressure plate 51 also stops moving, allowing the auxiliary plate 9 and the pressure plate 51 to be quickly adjusted to the designated position.

[0066] Reference Figure 7 When the control lever 531 rotates in the reverse direction, the auxiliary plate 9 can move upward to engage with the threaded groove 62. An auxiliary sleeve 91 is provided inside the auxiliary plate 9, and the auxiliary sleeve 91 is fitted over the control lever 531. A connecting plate 92 and a spring 93 are provided inside the auxiliary sleeve 91. The connecting plate 92 is slidably fitted inside the auxiliary sleeve 91, and engages with the threaded groove 62 and the annular groove 64. That is, the auxiliary plate 9 moves up and down outside the control lever 531 via the connecting plate 92. The spring 93 is a spring that is connected to both the connecting plate 92 and the auxiliary sleeve 91, and is used to drive the connecting plate 92 to move upward.

[0067] Initially, the connecting plate 92 engages with the annular groove 64 at the bottom of the threaded groove 62. At this time, when the control rod 531 rotates and drives the pressure plate 51 to move downward, the connecting plate 92 always engages with the annular groove 64. When the control rod 531 rotates in the opposite direction, the spring 93 drives the connecting plate to engage with the threaded groove 62, so that the connecting plate 92 can be driven to move upward under the action of the threaded groove 62, thereby adjusting the position of the auxiliary plate 9.

[0068] When it is necessary to move the pressure plate 51 and the auxiliary plate 9 downward, adjust the rotation direction of the control lever 531. The intermediate ring 535 and the connecting plate 92 move downward under the gravity of the pressure plate 51 and the auxiliary plate 9, so that the intermediate ring 535 engages with the first thread groove 61 and the connecting plate 92 engages with the second thread groove 62, thereby driving the pressure plate 51 and the auxiliary plate 9 downward. After the connecting plate 92 moves into the second annular groove 64 below the second thread groove 62, it stops moving, while the intermediate ring 535 continues to move, working with the scraper 52 to clean the blockage layer on the upper surface of the resin.

[0069] During backflushing, the screw 42 drives the adjusting ring 43 to move upward, and the sliding part 32 moves upward to its initial position under the action of the elastic telescopic rod 323. At this time, the pressure plate 51 is still above the sliding part 32. When cleaning the blockage layer, impurities and some resin are cleaned to the top of the retaining ring 431. During backflushing, the screw 42 drives the adjusting ring 43 to move upward, so that the resin on the retaining ring 431 re-enters the sliding part 32. At the same time, under the action of the backflushing water flow, the impurities are backflushed to the outside of the tank 1, and the resin in the collection chamber 11 is transferred back to the sliding part 32 so that the hard water can be softened again after backflushing.

[0070] Reference Figure 3 A guide slope 432 is provided above the retaining ring 431, and the side of the guide slope 432 near the sliding part 32 slopes downward. This is so that during backflush, the resin in the collection chamber 11 enters the sliding part 32 under the action of the guide slope 432.

[0071] The implementation principle of this invention is as follows: When cleaning the blockage on the resin surface is required for hard water treatment, the second driving component 41 drives the adjusting ring 43 downward via the screw 42. The adjusting ring 43 drives the sliding part 32 downward via the first retaining ring 431 and the second retaining ring 321, so that the upper end of the sliding part 32 moves below the blockage layer. The first driving component 532 drives the scraper 52 to rotate via the control rod 531, scraping the blockage layer above the resin into the collection chamber 11. When the control rod 531 drives the scraper 52 to rotate, it drives the intermediate ring 535 to move downward, and the pressure plate 51 abuts against the upper surface of the resin. The intermediate ring 535 moves relative to the pressure plate 51 and compresses the elastic element 1. After the scraper 52 scrapes off the upper layer of resin, the pressure plate 51 moves downward under the action of the elastic element 1 536, so that the pressure plate 51 engages with the sliding part 32 again. The above operation is repeated to clean the blockage layer, so that the hard water and resin are in full contact, improving the treatment efficiency.

[0072] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
