Description

Technical Field

[0001] The present invention relates to the technical field of swimming machines, and in particular to a swimming device integrating countercurrent swimming, constant temperature heating, and sterilization and filtration. Background Art

[0002] Standard swimming pools are expensive, energy-intensive, and water-intensive, posing significant health and safety risks. These issues have hindered the widespread adoption of swimming. Infinity pools, above-ground swimming pools, and other alternatives to standard swimming pools, all have their own drawbacks, hindering widespread adoption.

[0003] Infinity pool: A special hydraulic propulsion device is used to form a directional water flow. Swimmers swim against the current in the pool to achieve the purpose of swimming. Similar to a treadmill, because of the propulsion of the water flow, swimmers cannot swim to the edge of the pool, so it is called an infinity pool.

[0004] Existing products often use plastic materials like acrylic and fiberglass for the pool body. A metal frame supports the pool and houses peripheral electrical, plumbing, and decorative materials. These are often equipped with sand filters, filter pumps, and thermostatic heating systems. Due to their usage requirements, pools require a certain length, often exceeding 4 meters. Existing finished products, many of which also function as massage bathtubs, are often over 2 meters wide and 1.2 meters high. This bulk and weight typically require forklifts and cranes for transportation and loading. The high cost of materials, transportation, installation, and maintenance contributes to their high price, limiting their popularity as high-end recreational equipment in today's society.

[0005] Swimming pools with brackets are constructed from a steel frame and meshed polyether vinyl (PVC) fabric. The main structure is supported by steel pipes, while the pool body is formed using high-frequency welding and heat treatment of a woven, double-sided PVC-coated nylon fabric specifically designed for pools. They offer excellent tear resistance, abrasion resistance, and aging resistance, and are aesthetically pleasing. They are also easy to set up, safe to use, and hygienic, requiring no dedicated site. Swimming pools with brackets are typically rectangular in shape, but can be customized to suit the site. They typically range in height from 60cm to 150cm, with dimensions ranging from 2x2m to 50x80m. They are primarily used for recreational swimming, but some also utilize hydraulic propulsion for swimming training. They can also be equipped with filtration and heating systems.

[0006] Existing filtration systems for swimming pools with brackets typically utilize centrifugal pumps with hair filters / collectors and sand filters to filter water. These systems can incorporate disinfection equipment and heating / temperature control equipment. Existing products typically require two or more motors for the hydraulic drive unit and filter pump, resulting in high costs. Both the filtration and heating systems require specialized installation and deployment.

[0007] Based on the above realities, designing an integrated swimming equipment with countercurrent swimming, sterilization filtration and constant temperature heating that can effectively reduce manufacturing cost, transportation cost and construction cost is a necessary condition for popularizing swimming among the whole people.

[0049] The upper flow guide filter is installed above the second water flow outlet in the horizontal direction of the deflector; one side of the upper flow direction switching plate is installed below the upper flow guide filter and is connected to the deflector housing by an elastic hinge. In the absence of external force, the other side of the upper flow direction switching plate is pulled downward by an elastic mechanism and rotated upward around the hinge to close the second water flow outlet, cooperating with the foldable flow direction switching plate to divide the water flow output by the power motor;

[0050] The foldable flow direction switching plate is composed of two foldable loose-leaf plates connected by hinges. One side of the foldable flow direction switching plate is installed above the third water flow outlet of the deflector housing through an elastic hinge. In the absence of external pulling force, the other side of the foldable flow direction switching plate tilts upward, forming a front with the downward tilted side of the upper flow direction switching plate, so that part of the water flows downward into the second water flow outlet, and the remaining input water flows into the third water flow outlet. Rotating the stacked flow direction switching plate downward around the hinge closes the third water flow outlet. The width of the foldable flow direction switching plate is smaller than the inner diameter of the deflector. When swimming against the current, the water flow output direction is horizontal. The foldable flow direction switching plate folds at the bottom of the deflector to block the third water flow outlet. When sterilizing and filtering, the water flow output direction is vertically downward to enter the sterilizing and filtering box. The foldable flow direction switching plate unfolds, causing the water to flow to the third water flow outlet.

The ends of the flow direction switching plate pulling wire rope are respectively connected to the foldable flow direction switching plate and the upper flow direction switching plate. The flow direction switching plate pulling wire rope passes through the wire rope 90-degree guide and U-shaped guide component fixed to the housing of the diversion system. Pulling the U-shaped guide component backward rotates the foldable flow direction switching plate and the upper flow direction switching plate to close, enabling the diversion system to switch the water output.

[0052] The 90-degree guide for the steel wire rope is installed on the side panel of the deflector housing;

[0055] The upper sterilization box consists of a sterilization box shell, a UV germicidal lamp, and a UV lamp mounting bracket. The sterilization box shell is a waterproof and corrosion-resistant box. The top has a hole of the same size as the water outlet of the deflector, which serves as the water inlet of the sterilization box. The bottom of the sterilization box is hollowed out to serve as the water outlet. The sterilization box has a UV lamp mounting bracket installed inside the sterilization box.

The control panel is connected to the WIFI, Bluetooth, and 4G signal antennas, connected to the display screen to output images, connected to physical buttons to receive user operation inputs, and connected to the electronic controller, heating rod, electromagnetic constant temperature heating device, power motor, and sterilization UV lamp circuit.

[0058] The camera speed measurement module uses image recognition to identify and calculate the swimmer's displacement through a camera placed above the water surface, dynamically adjusts the speed of the power motor to automatically adjust the water flow rate;

[0059] The software functions of the electronic operation control module include pool water temperature monitoring function, working mode switching function, working parameter setting function, automatic speed regulation function, and timed task execution function; the pool water temperature monitoring function is transmitted by the water temperature sensor through the IO interface to provide parameters for the heating function, the electronic operation control module includes 9 working modes, the working mode switching function is to switch the working mode through key input and graphical display on the display screen, and the 9 working modes are standby, swimming, constant temperature-swimming, heating, heating + filtration, heating + filtration + UV sterilization, filtration, filtration + UV sterilization, and water injection; working parameters The data setting function sets the upper limit of the heating temperature, the motor speed value during filtration, and the power control value of the electric heater when using 220V voltage through key input and display. The automatic speed regulation function is that the camera speed measurement module provides the swimmer's displacement data to the electronic operation control module, and the electronic operation control module adjusts the power motor speed according to the displacement data to control the water flow speed. The timed task execution function sets the specified cycle and duration of filtration and sterilization tasks through the display and operation buttons; the specified temperature heating task; the specified cycle and duration of constant temperature task; the equipment switches and executes the corresponding functions according to the task.

[0060] The remote interactive function module uses the host computer to realize remote monitoring of the status information of the swimming pool.

[0120] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0121] A swimming device that integrates countercurrent swimming, constant temperature heating, sterilization and filtration, such as Figure 1 As shown, it includes: power and electronic control system 3, flow guidance system 2, heating and constant temperature system 4, sterilization and filtration system 5, electromechanical operation control and remote interaction system. Figure 2 The figure shows the application and installation layout of the swimming equipment of the present invention. An automatic speed regulating countercurrent swimming equipment integrating heating, sterilization and filtration is installed at one end of the bracket swimming pool 2. Figure 1 The flow diversion system 2, sterilization and filtration system 5, and heating and constant temperature system 4 are located inside the swimming pool, and the power and electronic control system 3 is outside the pool. Figure 19 , which includes a bracket for swimming 6, a drawstring 601, and as shown in the figure, the drawstring 601 is connected to the swimming pool bracket. Figure 19The 6011 and 6013 in the middle are fastened. As shown in the figure, the drawstring 601 is fastened to the connecting hole on the bottom plate of the backboard bracket at 6012. After the swimming pool is filled with water, under the action of pressure, the drawstring generates tension in the opposite direction of the backboard bracket to resist deformation of the PVC fabric.

[0122] The present invention uses an axial flow impeller driven by a motor as the water flow power source for countercurrent swimming and the power source of the filtration system. The water flow rate of the axial flow impeller is much greater than the flow rate of the centrifugal water pump, which gets rid of the dependence of existing products on the filter pump in the water filtration system, reduces costs, and gets rid of the problems of pressure resistance, waterproofness, and inconvenience in replacing filter materials of the filter container outside the pool.

[0123] The power and electronic control system includes a back plate bracket, a deflector and filter box mounting bracket, a power motor, an axial flow impeller, a mechanical seal base plate, a motor driver, a self-locking wire pulling mechanism, a motor cooling coil, an electronic controller, a water temperature sensor, a back plate bracket housing, a display screen, and operating buttons;

[0124] like Figure 4 The backplane bracket structure diagram shown in the figure includes a backplane 301, a bracket base 302, an industrial plug and water pipe connector mounting plate 303, and a movable wheel 304 of the backplane bracket. The backplane 301, the bracket base 302, the industrial plug and water pipe connector mounting plate 303 are all laser cut from iron plates with a thickness of more than 3mm.

[0125] The back panel 301 has laser-cut mounting holes for the power motor, power switch, control system, water flow direction switching wire motor and its mechanism, heater, thermostat, water temperature sensor, water inlet, AC input quick plug, etc.

[0126] The bracket base plate 302 has laser-cut movable axle mounting holes, welding positioning holes, etc.

[0127] The industrial plug and water pipe joint mounting plate 303 has an industrial plug mounting hole cut by laser.

[0128] like Figure 4 The back plate 301 shown is bent into a groove shape, the bracket bottom plate 302 is bent into a groove shape, the industrial plug and water pipe joint mounting plate 303 is welded to the back plate 301, and the two groove structures are welded into an L shape to enhance the structural strength and resist the extrusion deformation of the bracket swimming pool, so that the power system and filtration system in the pool can be stably perpendicular to the horizontal plane.

[0129] The movable wheel 304 of the backplane bracket is installed on the bracket base plate 302.

[0130] like Figure 5The power and electrical control structure shown in the figure features a self-locking pull mechanism 305 mounted on the upper portion of the backplate support 301. This mechanism provides tension and generates a position signal for switching the water flow output direction of the deflector within the pool. The self-locking pull mechanism pulls a wire rope to close or open the second and third water flow outlets of the deflector within the pool. The self-locking pull mechanism rotates a self-locking worm motor with a gear, causing the rack to move linearly, driving the wire rope attached to the rack within a metal pull rope conduit 30504 extending into the pool. The wire rope conduit 30504 passes through holes in the waterproof, sealed backplate support and the pool wall, enabling the external pool components to control the mechanical movement of the internal pool components under waterproof conditions. The self-locking pull mechanism 305 has two microswitches that automatically de-energize the motor and generate a level signal when the foldable flow direction switching plate 202 is closed or opened.

[0131] Figure 9 It is a structural schematic diagram of the self-locking pulling mechanism 305, including a wire pulling mechanism base plate 30501, a V-shaped wire bearing 30502, a wire pulling wire rope 30503, wire pulling wire rope metal conduits 30504 and 30509, micro switches 30505 and 30510, a wire pulling rack 30506, a switching plate stop switch wire pulling wire 30507, and a self-locking worm motor 30508. When the equipment is to switch between countercurrent swimming and sterilization filtration working modes, the self-locking worm motor 30508 is energized and rotates clockwise, driving the pull wire rack 30506 to move to the right in the groove of the bottom plate 30501 of the pull wire mechanism. When the pull wire rack 30506 moves, the pull wire rope 30503 connected to it is pulled and also moves to the right. The pull wire rope 30503 is connected to the U-shaped guide component 205 in the pool body along the pull wire rope metal conduit 30504. When the pull wire rope 30503 moves, the U-shaped guide component 205 moves synchronously to make the folding flow direction switching plate 202 of the deflector and the upper flow direction switching plate 207 rotate and close, completing the water flow output switching action to change to countercurrent swimming mode. When the foldable flow direction switching plate 202 is fully closed, the cable wire 30507 is pulled, closing the microswitch 30510 and generating a fully closed signal. The self-locking worm motor 30508 is de-energized and stops clockwise rotation. When the self-locking worm motor 30508 is energized and rotates counterclockwise, it drives the cable rack 30506 to the left within the groove of the cable mechanism base plate 30501. The cable wire 30503 is pulled leftward by the torque of the elastic hinge of the foldable flow direction switching plate 202. When the left end of the cable rack 30506 reaches the position of the microswitch 30505, the self-locking worm motor 30508 is de-energized and stops counterclockwise rotation, returning the deflector to sterilization and filtration mode. Cable wire conduits 30504 and 30509 are secured and sealed with glands.

[0132] The detailed structure of the electromagnetic water valve and its connector and the conduit 310 is as follows: Figure 10As shown, the water inlet of solenoid water valve 31003 of the solenoid water valve and its connector and conduit 310 passes through a hole in the industrial plug and water pipe connector mounting plate 303 and connects to a quick water pipe connector 31004, which is fastened to the industrial plug and water pipe connector mounting plate 303. The water outlet of solenoid water valve 31003 is connected to a corrugated conduit 31002, the other end of which is connected to an external threaded connector mounted on the plywood on the back plate 301. When solenoid water valve 31003 is energized, water can flow from outside the pool into the pool.

[0133] External liquid level sensor 313 Figure 5 As shown, it is installed on the back plate 301. Its detailed structure is as follows Figure 8 The device shown includes a perforated pipe cap 31301, a liquid level switch 31302, a switch mounting bracket 31303, a PVC pipe 31304, plywood pagoda connectors 31305 and 31307, and a conduit 31306. Figure 8 The external liquid level sensor shown is composed of PVC tubing 31304 as its main body. The liquid level switch 31302 is mounted on a perforated pipe cap 31301, which is mounted on the top of the PVC tubing 31304. The switch mounting bracket 31303 is mounted on the side panel of the back panel 301. The pagoda connector 31305 is mounted on the bottom of the PVC tubing 31304 and connected to the pagoda connector 31310 on the back panel 301 via a conduit 31306. By utilizing the principle that liquid levels in connected containers are equal under the same atmospheric pressure, this allows for external measurement of the pool water level. The external liquid level sensor 313 is installed by inserting it into the switch mounting bracket 31303 fixed to the side of the back panel 301. The screws on the switch mounting bracket 31303 allow the height of the external liquid level sensor 313 to be adjusted to the appropriate liquid level. The ideal operating water level is 2 to 5 cm above the top of the deflector. This allows for external water level measurement within the pool, simplifying the internal structure.

[0134] The electronic control execution unit 307 is installed on the side of the back plate 301. Figure 5 The electronic control execution unit 307 can control the on / off of four circuits with currents below 32A and withstand voltages below 400V, and the on / off of four circuits with currents below 10A and withstand voltages below 300V.

[0135] The industrial plug assembly 309 is mounted on the industrial plug and water pipe joint mounting plate 303. The industrial plug assembly 309 is as follows: Figure 11 The figure includes 3-core industrial plugs 30901 and 30902, 5-core industrial plug 30903, and the leakage protector group 308 with two-phase and three-phase power switching function. The function is to provide leakage protection for the equipment and protect the personal safety of users. The detailed structure is as follows Figure 11As shown, the RCDI device assembly 308, which supports two-phase and three-phase switching, consists of seven components: a 3P+N RCDI device 30801, 1P circuit breakers 30802, 30804, 30806, and 30807, and 1P+N RCDI devices 30803 and 30805. The RCDI device assembly 308 is connected by first connecting the neutral and live wires of the three-core industrial plug 30902 of the industrial plug assembly 309 to the neutral and live wires of the input terminals of the 1P+N RCDI device 30805. Then, the neutral and live wires of the three-core industrial plug 30901 of the industrial plug assembly 309 are connected to the neutral and live wires of the input terminals of the 1P+N RCDI device 30803. The neutral wire and live wires L1, L2, and L3 of the 5-core industrial plug 30903 of the industrial plug set 309 are connected to the neutral wire terminal and live wires L1, L2, and L3 terminals of the 3P+N leakage circuit breaker 30801.

[0136] like Figure 11 The method for implementing the two-phase and three-phase power switching function is characterized by comprising the following steps:

[0142] (6) The input terminal of the 1P circuit breaker 30802 is connected to the neutral terminal of the heating rod 401;

[0143] (7) The output neutral terminal of the 1P+N leakage circuit breaker 30803 is connected to the input terminal of the 1P circuit breaker 30804;

[0144] (8) The live wire output terminal of the 1P+N leakage circuit breaker 30803 is connected to the input terminal of the second of the four channels 32A of the electronic control execution unit 307, and the output terminal of the second of the four channels 32A of the electronic control execution unit 307 is connected to the live wire terminal of the heating rod 401;

[0145] (9) The output terminal of 1P circuit breaker 30804 is connected to the input terminal of 1P circuit breaker 30802;

[0146] (10) The output neutral terminal of the 1P+N leakage circuit breaker 30805 is connected to the input terminal of the 1P circuit breaker 30806;

[0147] (11) The output live wire terminal of the 1P+N leakage circuit breaker 30805 is connected to the input terminal of the 1P circuit breaker 30807;

[0148] (12) The live wire output terminal of the 1P+N leakage circuit breaker 30805 is connected to the input terminal of the third of the four channels 32A of the electronic control execution unit 307, and the output terminal of the third of the four channels 32A of the electronic control execution unit 307 is connected to the live wire terminal of the heating rod 402;

[0149] (13) The output terminal of the 1P circuit breaker 30806 is connected to the neutral terminal of the heating rod 403, and the neutral terminal of the heating rod 403 is connected to the neutral terminal of the heating rod 402;

[0150] (14) The output end of the 1P circuit breaker 30806 is connected to the input end of the fourth of the four 32A circuits of the electric control execution unit 307, and the output end of the fourth of the four 32A circuits of the electric control execution unit 307 is connected to the live wire end of the heating rod 403;

[0151] The flow guiding system 2 is as follows Figure 3 As shown, it includes a deflector housing 208, an axial flow guide vane 206, a grid-shaped deflector plate 201, a foldable flow direction switching plate 202, a flow direction switching plate pulling wire rope 203, a wire rope 90 degree guide 204, a U-shaped guide component 205, an upper flow direction switching plate 207, and an upper deflector filter 209.

[0152] The deflector housing 208 is designed as a housing with a rectangular three-way cavity as the main body, with one water flow inlet and three water flow outlets, such as Figure 3The right end of the shell 208 of the diversion system shown is the water inlet, the outlet at the position of the grid-shaped diversion plate 201 is the first water outlet, the outlet at the position of the upper diversion filter 209 is the second water outlet, and the outlet at the position of the wire rope 90-degree guide 204 is the third water outlet. The foldable flow direction switching plate 202 is installed above the third water flow outlet through an elastic hinge. It can be rotated downward around the hinge to close the third water flow outlet. The upper flow direction switching plate 207 is installed on the shell below the upper diversion filter 209 through an elastic hinge. It can be rotated upward around the hinge to close the second water flow outlet. The upper flow direction switching plate 207 uses an elastic mechanism to pull it so that it tilts downward with the hinge as the axis when there is no external force pulling. The elastic hinge of the foldable flow direction switching plate 202 allows it to tilt upward with the hinge as the axis when there is no external force pulling. The foldable flow direction switching plate 202 and the upper flow direction switching plate 207 form a front, allowing a small part of the water to flow upward into the second water flow outlet, and the remaining input water flow enters the third water flow outlet. The two ends of the flow direction switching plate pulling wire rope 203 are respectively connected to the foldable flow direction switching plate 202 and the upper flow direction switching plate 207. Figure 3 In the position shown, the flow direction switching plate pulls the wire rope 203 through the wire rope 90-degree guide 204 and the U-shaped guide component 205 fixed on the shell 208 of the diversion system, and pulls the U-shaped guide component 205 backward to rotate and close the foldable flow direction switching plate 202 and the upper flow direction switching plate 207, so that the diversion system can realize water flow output switching.

[0153] The deflector housing 208 of the deflector system is connected to one end of the power motor cooling coil. When the second and third water flow outlets are closed, the Bernoulli effect is applied to make the water in the cooling pipe flow toward the deflector to circulate and cool the motor. When the second and third water flow outlets are opened, the water pressure inside the deflector is greater than the water pressure outside the deflector. The fluid pressure causes the water in the deflector to flow into the cooling pipe to circulate and cool the motor.

[0154] The upper diversion filter 209 is installed at the second water flow output port of the diverter. The inclined guide plate inside the upper diversion filter 209 causes the water flowing out of the second water flow output port to deviate to one side of the pool wall, forming a circulating water flow in the pool, thereby improving the sterilization and filtration efficiency. The filter net inside the upper diversion filter 209 filters large particles in the water flowing through the second water flow output port.

[0155] The gridded deflector plate 201 is made of waterproof and corrosion-resistant material and features a crisscross grid structure. Its dimensions match those of the deflector's water outlet and it is positioned at one end of the outlet. Together, the gridded deflector plate 201 and the axial flow guide vanes 206 convert the spiraling water flow generated by the rotating axial flow impeller on the power motor into a horizontal, forward flow. A 90-degree wire rope guide 204 redirects the wire rope, while a U-shaped guide component 205 functions as a set of movable pulleys, pulling the wire rope. The upper deflector filter 209 circulates the swimming pool water over a wider area during sterilization and filtration, achieving higher filtration efficiency. An upper flow direction switching plate 207 is mounted in front of the upper deflector filter 209 and is hingedly connected to the deflector housing. It interacts with the foldable flow direction switching plate to divide the water flow output from the power motor. The majority of the water flows vertically into the sterilization filter tank, while a smaller portion flows horizontally through the upper deflector filter to the right or left, creating a circulating water flow within the pool.

[0156] The device power motor 311 and the device power motor driver 306 are as follows: Figure 5 It is shown mounted on the back panel 301 of the back panel bracket.

[0157] Equipment power motor cooling duct 312 such as Figure 12 As shown, the coil is mounted on the power motor 311, and both of its pipe openings pass through the holes on the back plate 301 where the Glen head is installed to enter the pool. Figure 13 The pipe opening 312012 shown is connected to the coil of the deflector and the deflector connector 210, and the pipe opening 312011 is placed in the pool. The diameter of the cooling conduit of the power motor of the equipment is 10 to 20 mm and is adjusted according to the motor power. When the deflector works in the countercurrent swimming mode, Figure 6 The water flow generated by the rotation of the central axial flow impeller 314 passes through the deflector housing at high speed in the horizontal direction. Due to the Bernoulli effect, a water flow from 312011 to 312012 is generated in the cooling duct 312 of the equipment power motor connected to the deflector housing, circulating cooling for the power motor. When the deflector works in the sterilization and filtration mode Figure 6 The water flow generated by the rotation of the central axial flow impeller 314 is changed in direction by the foldable flow switching plate 202, and enters the sterilization filter box vertically downward. After being blocked by the filter element, the water pressure in the deflector is greater than the water pressure outside the deflector. The fluid pressure difference causes a water flow from 312012 to 312011 in the cooling duct 312 of the equipment power motor to circulate and cool the power motor.

[0158] Heating thermostat system Figure 7As shown, it includes heating rods and electromagnetic constant temperature heating devices; wherein the heating rods use three heating rods of the same power, the heating portion of the heating rods is located in the swimming pool, and the tail of the heating rod passes through the holes of the PVC fabric pool wall and the backboard bracket and is installed on the backboard bracket; the electromagnetic constant temperature heating device is composed of an electromagnetic coil installed in the hole of the backboard bracket and a heating plate in the swimming pool, and uses the electromagnetic heating effect to achieve water-electricity isolated constant temperature heating;

[0159] The sterilization and filtration system 5 includes an upper sterilization box, a lower filter box, and a connecting buckle; wherein the upper sterilization box is installed on the deflector and the filter box mounting bracket, is tightly connected to the water flow outlet in the vertical direction of the deflector, and is provided with a UV sterilization lamp; the lower filter box is connected to the upper part of the sterilization and filtration box through the connecting buckle to achieve detachable assembly and assembly, and a PP cotton filter element is provided in the lower filter box, and a perforated baffle is provided on the top of the lower filter box and a bottom plate is provided at the bottom to clamp the PP cotton filter element, and the PP cotton filter element is replaced by opening the bottom plate of the lower filter box; the connecting buckle is used to connect and fasten the lower filter box to the upper sterilization box.

[0160] The water flow of the sterilizing and filtering system 5 is generated by the rotation of the impeller 314. After entering the deflector, the water flow is changed in direction by the unfolded foldable flow direction switching plate 202 and enters the sterilizing and filtering box vertically downward.

[0161] Combine Figure 14 , Figure 15 , Figure 16 In summary, in this embodiment, 12 10-inch PP cotton filter elements 50102 are used. The 10-inch PP cotton filter element 50102 is a cylinder with a bottom diameter of 60 mm and a height of 254 mm. The 12 10-inch PP cotton filter elements 50102 are arranged in a 3X4 layout. Adding the spacing space for comprehensive calculation, the overall size of the sterilization filter box is 340 mm in length, 280 mm in width, and 422 mm in height.

[0162] like Figure 15 As shown, the sterilization box consists of five housing surfaces. A hole of the same size as the third outlet of the deflector is located on the top surface of the sterilization box, serving as the water outlet for the sterilization box. The dimensions of the top surface of the sterilization box are the same length and width as the filter box. The cross-sectional dimensions of the four side panels are slightly smaller than those of the filter box, allowing the sterilization box to be nested within the upper portion of the filter box. In this embodiment, the sterilization box height is 100 mm, which can be adjusted based on parameters such as the size and power of the UV lamp.

[0163] like Figure 15The following is a schematic diagram of the structure of a sterilization box in a sterilization and filtration system according to the present invention. The sterilization box includes a hook 50301 for fastening a buckle, a housing 50201, a UV lamp power cord and a sealing bead 50202, a UV lamp mounting bracket 50203, and a UV germicidal lamp 50204. The UV germicidal lamp 50204 is mounted on the UV lamp mounting bracket 50203, which is mounted on the housing 50201 of the sterilization box. The UV lamp power cord runs from the inside of the sterilization box through a small hole in the top of the housing 50201 of the sterilization box to the outside of the box. It then passes through a hole in the back panel 301, which is equipped with a gland, and connects to the electronic controller 307 on the back panel. 307 controls the on / off circuit of the UV lamp, turning the sterilization function on and off.

[0164] like Figure 16 The filter box, shown in the figure, is a schematic diagram of the structure of the sterilizing filtration system of the present invention. The filter box includes a water outlet 50101, a 10-inch PP cotton filter element 50102, a filter box bottom plate 50103, filter box locking screws 50104, and a filter element upper partition 50105. The filter box uses 12 10-inch PP cotton filter elements 50102. Four filter box locking screws 50104 are fixed to the filter element upper partition 50105. The length is 3 to 5 cm longer than the height of the 10-inch PP cotton filter element 50102. The filter box bottom plate 50103 is removable and has four holes on it that correspond to the fixing positions of the four filter box locking screws 50104. The filter box bottom plate 50103 is installed through these holes and is locked with a hand nut. After entering the filter box, the water flows into each 10-inch PP cotton filter element 50102 through the 12 holes of the filter element upper partition 50105, seeps out from the outer surface of the 10-inch PP cotton filter element 50102, and enters the swimming pool through the filter box outlet 50101 on the surface of the filter box, thereby achieving pool water filtration.

[0165] like Figure 18 As shown in the structural diagram of the deflector and sterilizing filter box mounting bracket of the present invention, the deflector and sterilizing filter box mounting bracket 321 is fastened to the back plate 301 using hexagonal flange double-headed screws 322. The deflector and sterilizing filter box mounting bracket 321 should be made of structurally reinforced and corrosion-resistant materials. In this embodiment, 25mm*25mm304 stainless steel pipes are used for welding.

[0166] Combine Figure 15 、 Figure 18 The deflector is mounted on the upper surface of the deflector and sterilizing filter box mounting bracket 321 and fastened with screws. The sterilizing box is mounted on the lower surface of the deflector and sterilizing filter box mounting bracket 321 and fastened with screws.

[0167] After assembly, the third water outlet of the deflector is tightly connected to the water inlet of the sterilizer, and the joint is sealed with waterproof sealant. Figure 14 As shown, the filter box is connected to the sterilization box using six buckles to achieve replacement of the filter element.

[0168] Combine Figure 17 , the present invention's housing, operating buttons and display structure diagram, including the backplane support housing 317, operating buttons 318, display screen 319, deflector housing 320. Figure 17 As shown, the display screen 319 and the operation button 318 are installed on the back panel support shell 317, and the back panel support shell 317 is installed on the back panel 301. Figure 17 The back panel bracket housing 317, shown above, features a windowed area where the screen is mounted, and a transparent panel is installed. Waterproof sealant is applied to the interface between the transparent panel and the back panel bracket housing 317. Mounting holes are provided on the transparent panel based on the size and number of the operating buttons. The operating buttons 318 are waterproof mechanical buttons, providing both waterproof and dustproof protection, allowing the device to be used outdoors in a variety of weather conditions. The deflector housing 320, mounted on the deflector and sterilizing filter mounting bracket 321, covers the deflector and heater rod, preventing bubbles from being generated by the siphon effect when the axial flow impeller rotates and affecting the water flow rate.
