[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a swimming pool circulation filtration device, which includes a filter element 100, a reversing element 200, and a drainage element 300.

[0034] Specifically, the filter element 100 includes a filter tube 101, an inlet cone tube 102, and an outlet sewage pipe 103. The inlet cone tube 102 is located at one end of the filter tube 101, and the outlet sewage pipe 103 is located on the side of the inlet cone tube 102.

[0035] Water enters through the inlet cone pipe 102 and is filtered as it passes through the filter pipe 101. The outlet sludge pipe 103 is used to carry water after cleaning the filter screen. The filter element 100 is used to filter the pool water and remove water containing impurities.

[0036] Specifically, the reversing component 200 is located on one side of the filter element 100 and includes a reversing box 201, a flexible drum 202, and a reversing spring 203. The reversing box 201 is located at the other end of the filter tube 101, the flexible drum 202 is located at the bottom of the reversing box 201, and the spring 203 is sleeved on the outside of the flexible drum 202.

[0037] After the filter screen has filtered a lot, the reversing component 200 will change the direction of water flow. During the filtration process, the soft bucket 202 will slowly fill with water and will stretch, which will cause the reversing spring 203 to also stretch. After the reversing component 200 rises to the top, it will descend to reverse the water flow in the filter tube 101, clean the impurities on the filter screen, and the cleaned water will be discharged from the drain pipe 103.

[0038] Specifically, the drainage component 300 is located on one side of the reversing component 200 and includes a drainage pipe 301 and a support base 302. The drainage pipe 301 is located on one side of the reversing box 201, and the support base 302 is located at the bottom of the drainage pipe 301.

[0039] The support base 302 is fixed to the bottom of the pool, securing the entire device.

[0040] Specifically, the filter element 100 also includes a translation element 104 and a lifting element 105. The translation element 104 is disposed in the middle of the filter tube 101, and the lifting element 105 is disposed on one side of the translation element 104.

[0041] During the filtration process, the translation component 104 will slowly move to the right as the filtration volume of the filter increases. The lifting component 105 will move to the right synchronously with the translation component 104, and at the same time, the lifting component 105 will also move downward.

[0042] Specifically, the translation component 104 includes a bottom limiting block 104a, a first rod 104b, a first spring 104c, and a piston head 104d. The bottom limiting block 104a is vertically arranged on the axis of the filter tube 101, the first rod 104b is arranged on one side of the bottom limiting block 104a, the first spring 104c is sleeved on the outside of the first rod 104b, and the piston head 104d is arranged at one end of the first rod 104b.

[0043] One end of the first spring 104c is fixed to the piston head 104d, and the other end is fixed to a ring of protrusions inside the filter tube 101.

[0044] Specifically, the translation component 104 includes a filter plate 104e, which is sleeved on the outside of the first rod 104b and fits against the bottom limiting block 104a. The bottom limiting block 104a has limiting protrusions 104a-1 at both ends, and the remaining four sides of the bottom limiting block 104a have long limiting holes H1. The inner wall of the filter tube 101 has a long limiting groove H2, and the limiting protrusions 104a-1 and the long limiting groove H2 cooperate with each other.

[0045] During the filtration process, the surface of the filter plate 104e will gradually be covered by impurities, which will reduce the filtration capacity and increase the intensity of water flow impact. As a result, the filter plate 104e will be slowly pushed to the right, which will also drive the entire translation component 104 to move to the right.

[0046] Specifically, the lifting component 105 includes a limiting short rod 105a, a second rod 105b, and a first tube 105c. The limiting short rod 105a is located at one end of the second rod 105b, and the first tube 105c is located at the middle of the side of the second rod 105b. The limiting short rod 105a and the long limiting hole H1 of the bottom limiting block 104a are engaged.

[0047] The limiting rod 105a is square, ensuring that the lifting component 105 will not rotate but will only move up and down along the long limiting hole H1 of the bottom limiting block 104a.

[0048] Specifically, the lifting component 105 also includes a second spring 105d and a third rod 105e. The second spring 105d is located inside the first tube 105c, and there are two third rods 105e, which are respectively located at both ends of the second spring 105d.

[0049] When the end face of rod 105e is subjected to force during movement, it will move into tube 105c and compress spring 105d.

[0050] Specifically, the filter element 100 also includes a one-way plate 106, which is disposed inside the outlet sewage pipe 103 and includes a fixed column 106a, a fixed semicircular plate 106b and a movable semicircular plate 106c. The fixed column 106a is rotatably connected to the inner wall of the outlet sewage pipe 103, the fixed semicircular plate 106b and the fixed column 106a are fixedly connected, and the movable semicircular plate 106c and the fixed semicircular plate 106b are hinged together.

[0051] When the water flows to the right for filtration, the movable semicircular plate 106c and the fixed semicircular plate 106b form a complete ellipse, blocking most of the outlet sewage pipe 103. When the water flows to the left to clean the filter residue, the piston head 104d blocks the inlet cone pipe 102. The movable semicircular plate 106c is impacted by the water flow and forms an angle of about 90 degrees with the fixed semicircular plate 106b. The outlet sewage pipe 103 is opened halfway, and the water used to clean the filter residue flows away from the outlet sewage pipe 103.

[0052] In use, the filter element 100 filters the pool water and removes water containing impurities. The reversing element 200 changes the direction of water flow after the filter screen has filtered a lot of water, and the drain element 300 allows the filtered water to flow in and fixes the entire device in place.

[0053] When the water flows to the right for filtration, the movable semicircular plate 106c and the fixed semicircular plate 106b form a complete ellipse, blocking most of the outlet sewage pipe 103. When the water flows to the left to clean the filter residue, the piston head 104d blocks the inlet cone pipe 102. The movable semicircular plate 106c is impacted by the water flow and forms an angle of about 90 degrees with the fixed semicircular plate 106b. The outlet sewage pipe 103 is opened halfway, and the water used to clean the filter residue flows away from the outlet sewage pipe 103.

[0054] Example 2

[0055] Reference Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0056] Specifically, the reversing box 201 includes a first top surface 201e, a first bottom surface 201f, a first side surface 201a, a second side surface 201b, and a third side surface 201c. The filter pipe 101 passes through and is fixedly connected to the first side surface 201a. The drain pipe 301 is attached to the second side surface 201b. There are two third side surfaces 201c, which are symmetrically arranged between the first side surface 201a and the second side surface 201b.

[0057] The commutator box 201 has six sides, among which the third side 201c is symmetrically arranged and has the same structure.

[0058] Specifically, the third side 201c is provided with a ring limiting groove H3, and the upper left and lower left corners of the ring limiting groove H3 are provided with limiting wedges 201c-1, and the third rod 105e cooperates with the ring limiting groove H3.

[0059] Because of the obstruction of the limiting wedge block 201c-1, rod 105e can only move in one direction within the ring limiting groove H3 and cannot turn back.

[0060] Specifically, the top of the soft bucket 202 is connected to the first bottom surface 201f. The top of the reversing spring 203 is engaged with the first bottom surface 201f, and the bottom is engaged with the bottom of the soft bucket 202. The drainage component 300 also includes a water-blocking ring 303 and a vertical shifting column 304. The water-blocking ring 303 is sleeved on the outside of the drain pipe 301. The water-blocking ring 303 is in contact with the second side surface 201b. The vertical shifting column 304 is set at one end of the drain pipe 301. The second side surface 201b is provided with a water passage hole H4 and a vertical shifting groove H5. The drain pipe 301 is engaged with the water passage hole H4, and the vertical shifting column 304 is engaged with the vertical shifting groove H5.

[0061] During the water filtration process, the soft bucket 202 slowly fills with water and stretches itself, simultaneously stretching the reversing spring 203. The vertical column 304 is located within the vertical groove H5, ensuring that the reversing component 200 remains perpendicular to the drain pipe 301 when moving up and down.

[0062] In the initial stage of use, the filter plate 104e experiences rapid water flow and experiences relatively low pressure from the water flowing to the right. As time progresses, more and more impurities accumulate on the filter plate 104e, gradually increasing the pressure from the water flowing to the right. The filter plate 104e is pushed to the right, simultaneously causing the translation component 104 to move to the right, compressing the first spring 104c. The rightward movement of the translation component 104 then causes the lifting component 105 to move to the right. Due to the engagement of the annular limiting groove H3 on the third rod 105e and the third side 201c, the lifting component 105... When 5 moves to the right, it will simultaneously act on the ring limiting groove H3, causing the third side 201c to move upward, which in turn drives the reversing component 200 and the filter component 100 to move upward. The reversing box 201 slowly rises until the water passage hole H4 of the second side 201b and the drain pipe 301 slowly separate, reducing the water flow speed of the drain pipe 301. The soft bucket 202 will receive this water and stretch itself, while simultaneously stretching the reversing spring 203. The force on the reversing spring 203 is balanced by the upward force of the third rod 105e on the ring limiting groove H3.

[0063] When rod 105e passes the lower right corner limiting wedge 201c-1, the contact point between rod 105e and the ring limiting groove H3 changes from the bottom of the inner wall of the ring limiting groove H3 to the right side of the outer wall of the ring limiting groove H3. The direction of the force exerted by rod 105e on the ring limiting groove H3 changes from upward to rightward, while side 201c cannot move to the right. At this time, the reversing spring 203 begins to contract, discharging the water in the soft bucket 202. Since the water passage hole H4 and the drain pipe 301 of side 201b are misaligned, the water will move to the left, backwashing the filter plate 104e. At the same time, the water moving to the left will move the semicircular plate 106c open, pushing the piston head 104d into the inlet cone pipe 102. The water containing impurities that is flushed out is discharged from the outlet sewage pipe 103.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
