Description

Technical Field

[0001] This invention relates to the field of water pollution control and treatment technology, and in particular to a wastewater recycling treatment device. Background Technology

[0002] Water pollution control in water conservancy projects is a complex and systematic undertaking, involving multiple aspects such as technology, management, law, economy, and social participation. Its core objectives are to reduce pollutant emissions, improve water quality, restore aquatic ecosystems, and ensure the safe and sustainable use of water resources. Physical filtration is one of the commonly used primary or pretreatment methods in water pollution control. It mainly uses media such as filter screens, filter plates, or filter media to intercept suspended solids, particulate matter, and other impurities in the water to achieve preliminary water purification.

[0003] A search revealed that patent document CN221771717U discloses a wastewater recycling treatment device, including a filter box, a purification box, and a filter screen. The filter box has a socket, and the socket contains a plug and a first spring. One surface of the plug has a slot. Crossbars are installed on both sides of the filter box, and sliding plates and a second spring are installed on the periphery of the crossbars. The sliding plates are connected to the plugs, and the crossbars are connected to a limiting plate. One surface of the limiting plate has a slot, in which a pull rod is installed. The filter screen is engaged with the filter box. By engaging the filter screen with the filter box, after wastewater treatment, pulling the pull rods to both sides moves the plug away from the slot via the sliding plate. When the plug is removed from the slot, the second spring resets, causing the plug to spring upwards and pop out of the socket. The filter screen can then be pulled upwards out of the filter box to complete the removal of the filter screen. The surface of the filter screen can then be cleaned, making the operation convenient. In existing technologies, filtration equipment is mostly a single-box structure or a design that requires shutdown for filter element replacement. In actual operation, the filter box or filter media gradually becomes clogged after intercepting impurities, leading to decreased filtration efficiency, reduced treatment capacity, and even system shutdown. To restore treatment capacity, operators must stop the equipment and remove the clogged filter unit for cleaning or replacement. This process not only interrupts the wastewater treatment process and affects overall operational efficiency, especially in scenarios with high requirements for continuous treatment (such as some industrial production lines), causing production inconvenience; but the frequent disassembly and installation operations are also cumbersome, increasing maintenance workload and time costs.

[0004] Furthermore, existing wastewater treatment equipment covers are typically connected using bolts, which makes opening and closing inconvenient and hinders routine inspections, maintenance, and emergency response. The internal structure also often lacks flexible switching and backup mechanisms; when the main filter unit fails or becomes clogged, the backup unit cannot be quickly activated, resulting in insufficient system reliability. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a wastewater recycling treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wastewater recycling treatment device, comprising: The wastewater treatment tank and the cover on top of the wastewater treatment tank are equipped with an observation port, and a transparent plate is fixedly installed inside the observation port; this allows for real-time observation of the wastewater treatment status and filtration process inside the tank. A connecting assembly, located on the sewage treatment tank and its cover, enables quick assembly and disassembly of the cover. The connecting assembly includes two rectangular plates and two connecting fixing seats. The two rectangular plates are fixedly installed on both sides of the sewage treatment tank, and the two connecting fixing seats are fixedly installed on the top of the cover. Each rectangular plate has a horizontal rectangular locking hole. Each connecting fixing seat has a second reset groove on its opposite side. A rectangular insert plate is slidably installed in each of the two second reset grooves. The opposite sides of the two rectangular insert plates engage with the two horizontal rectangular locking holes. A second reset spring is fixedly installed on the opposite sides of the two rectangular insert plates. One end of the second reset spring is fixedly connected to the inner wall of the second reset groove. The inner walls of both sides of the trough are provided with second sliding grooves. Second sliding blocks are fixedly installed on both sides of the rectangular insert plate. The outer sides of the two second sliding blocks slide in contact with the inner walls of the two second sliding grooves. Push-pull plates are fixedly installed on the tops of the two rectangular insert plates. By pushing the two push-pull plates in opposite directions, the second return spring is compressed, causing the rectangular insert plates to disengage from the horizontal rectangular locking holes, thus quickly releasing the lock on the tank cover for easy opening for inspection or cleaning. The two push-pull plates facilitate the movement of the two rectangular insert plates. The top of the sewage treatment tank has multiple positioning slots, and the bottom of the tank cover has multiple positioning blocks fixedly installed. These positioning blocks engage with the multiple positioning slots, ensuring accurate alignment and initial positioning during tank cover installation. A partition plate is fixedly installed inside the wastewater treatment tank, dividing the tank into two filtration chambers. Two mounting ports are located on both sides of the wastewater treatment tank. A main filter collection box and a backup filter collection box are movably installed in each port. Both the main and backup filter collection boxes have openings on their tops and one side. Filter plates are fixedly installed in one side opening of each box to intercept solid impurities in the wastewater. A main water inlet and a backup water inlet are respectively located on the other side of each box. Positioning seats are fixedly installed on both sides of the wastewater treatment tank. A first reset groove is opened on one side of each positioning seat, and a limit plate is slidably installed in each of the two first reset grooves. This device is used to limit the movement of the main filter collection box and the backup filter collection box on opposite sides. A first reset spring is fixedly installed on one side of the inner wall of each of the two first reset slots. The other end of the first reset spring is fixedly connected to the corresponding limiting plate. The spring force automatically pushes the limiting plate towards the outside of the main or backup filter collection box, achieving automatic locking after installation. First sliding grooves are provided on the inner walls of both sides of the first reset slot. First sliding blocks are fixedly installed on both sides of the limiting plate. The outer sides of the two first sliding blocks slide in contact with the inner walls of the two first sliding grooves. The arrangement of the first sliding blocks and the first sliding grooves ensures smooth movement of the limiting plate and prevents skewing or jamming.

[0007] The mounting plate is fixedly installed inside the sewage treatment tank. One side of the mounting plate contacts the outside of the main filter collection box and the backup filter collection box. A fixing seat is fixedly installed on the top of the mounting plate. The fixing seat is provided with a diversion hole. The diversion hole introduces external sewage and distributes it to the target filter channel. An inlet pipe is fixedly installed on one side of the sewage treatment tank. One end of the inlet pipe is fixedly connected to the middle section of the diversion hole. Two drain holes are located at the bottom of one side of the wastewater treatment tank to discharge filtered wastewater. The two drain holes are located in the two filter chambers respectively. A filter channel switching mechanism, located on the wastewater treatment tank, is used to switch between the main filter collection tank and the standby filter collection tank. When the main filter collection tank is clogged or needs cleaning, it can be quickly switched to the standby tank to ensure uninterrupted treatment. The filter channel switching mechanism includes two sealing plates that alternately close the two openings of the diversion hole. Rectangular rods are fixedly installed on the opposite sides of the two sealing plates. Rectangular sliding holes are provided on both sides of the wastewater treatment tank, and the two rectangular rods are slidably installed within these holes. Vertical plates are fixedly installed on the opposite sides of the two rectangular rods, and connecting rods are fixedly installed on one side of each of the two vertical plates. A common transmission plate is fixedly installed between the two connecting rods, located on one side of the wastewater treatment tank. A support plate is fixedly installed on the side of the treatment tank near the transmission plate. A groove is formed at the bottom of the support plate, and two sliders are slidably installed within the groove. The bottoms of both sliders are fixedly connected to the top of the transmission plate. A limit rod is fixedly installed within the groove, and both sliders are slidably connected to the limit rod, allowing the transmission plate to slide stably at the bottom of the support plate. A first locking groove and a second locking groove are formed at the top of the transmission plate. A mounting block is fixedly installed on one side of the sewage treatment tank. A vertical hole is formed on the mounting block, and a locking rod is slidably installed within the vertical hole. The bottom end of the locking rod engages with the first locking groove. A pull block is fixedly installed on the top of the locking rod, and a spring is sleeved on the outside of the locking rod. One end of the spring is fixedly connected to the top of the mounting block, and the other end of the spring is fixedly connected to the bottom of the pull block. Two guide rods are fixedly installed on one side of the wastewater treatment tank. A movable plate is slidably mounted on each guide rod. A baffle is fixedly installed on one side of each movable plate. One side of each baffle slides in contact with the two sides of the wastewater treatment tank. The two baffles alternately limit the movement of the main filter collection tank and the standby filter collection tank on opposite sides. The sides of the main filter collection tank and the standby filter collection tank that are close to each other contact the sides of a partition plate. A locking plate is fixedly installed on both sides of the partition plate. A locking groove is provided on the side of the main filter collection tank and the standby filter collection tank that are close to each other. The two locking plates engage with the two locking grooves. A handle is fixedly installed on the side of the main filter collection tank and the standby filter collection tank that are far apart from each other. A screw is fixedly installed at the bottom of the support plate. The plate and screw mounting plate have a first screw and a second screw rotatably mounted on one side. A first gear and a second gear are fixedly mounted on the outer sides of the first and second screws, respectively. The first and second screws are threadedly connected to two movable plates. A fixed opening is provided at the bottom of the transmission plate, and a rack is fixedly mounted inside the opening. The rack meshes with the first gear, and the first gear meshes with the second gear. The linear motion of the transmission plate drives the gears to rotate, which in turn drives the two screws to rotate synchronously in opposite directions, realizing the relative or opposite movement of the two movable plates and baffles. This completes the linkage locking and unlocking of the main and backup filter collection boxes. Two round holes are opened on each side of the sewage treatment tank, and round rods are slidably mounted in each of the four round holes. A U-shaped plate is fixedly mounted at one end of two round rods on the same side.Two U-shaped plates are fixedly connected at their adjacent sides to the opposite sides of two vertical plates. The other ends of two round rods are fixedly fitted with the same opening / closing plate, which alternately closes two drainage holes. Each drainage hole contains a drain pipe, one end of which is fixedly connected to the same manifold box. A discharge pipe is fixedly connected to one side of the manifold box.

[0008] Compared with the prior art, the advantages of the present invention are as follows: Achieving uninterrupted maintenance and continuous treatment: By setting up a main filter collection box, a backup filter collection box, and a filter channel switching mechanism, when the main filter collection box in use needs cleaning due to impurity accumulation, it can be quickly switched to the backup filter collection box to continue operation. Operators can remove the full main filter collection box for cleaning without shutting down the equipment, greatly reducing interruptions to the wastewater treatment process, ensuring the continuity of system operation and overall treatment efficiency, and is especially suitable for industrial scenarios with high continuity requirements.

[0009] Simple operation and efficient switching: The switching of filter channels is achieved through an integrated linkage mechanism (transmission plate, rack, gear, screw, etc.). Users only need to operate the locking lever and transmission plate to simultaneously switch the inlet and outlet channels and lock the spare filter box, achieving "one-button" switching. This design simplifies complex multi-step operations into a single, continuous action, significantly reducing operational difficulty and maintenance time costs.

[0010] Stable and reliable operation with excellent sealing: Multiple positioning and locking mechanisms are designed. The main or backup filter collection box is secured by limit plates, locking plates, and movable baffles, ensuring stable positioning during operation. The filter channel switching mechanism, through the cooperation of a locking rod and locking groove, firmly holds the transmission plate in a specific position, preventing accidental movement. Simultaneously, the linkage design of the closing plate and the opening / closing plate ensures reliable sealing of the non-working side channels, preventing water short-circuiting or leakage, and improving the stability and reliability of system operation.

[0011] Easy to observe and quick to repair: The cover is equipped with a transparent panel, which allows for real-time observation of the internal operation of the equipment and the degree of impurity accumulation in the filter box. The cover is fixed to the box body by connecting components (rectangular insert plate, second return spring, etc.), and the cover can be quickly installed and removed without tools, which greatly facilitates daily inspection, maintenance and emergency handling.

The bottom of the tank cover 2 is fixedly installed with multiple positioning blocks. The multiple positioning blocks are respectively engaged with the multiple positioning slots 51.

[0025] Working principle: I. Initial equipment status; The filter channel switching mechanism is in its initial position, such as the main filter position. At this time, the locking rod 24 is engaged in the second locking groove 22 of the transmission plate 20 under the action of the spring 25, fixing the position of the transmission plate 20.

[0026] At this workstation, one of the sealing plates 17 seals the opening on the fixed base 12 through the diversion hole 13 leading to the side of the spare filter collection box 59, while the opening leading to the side of the main filter collection box 6 is open.

[0027] At the same time, one baffle 37 is in the extended state, restricting the main filter collection box 6 away from the partition plate 4 so that it will not easily detach, while the other baffle 37 is in the retracted state, not restricting the backup filter collection box 59.

[0028] During the main filtration station, the opening and closing plate 58 of the drain hole 44 corresponding to the filter chamber where the main filter collection box 6 is located is pulled open, and the drainage channel is opened; while the drain hole 44 corresponding to the filter chamber where the backup filter collection box 59 is located is closed by its opening and closing plate 58.

[0029] II. Wastewater filtration treatment, taking the main filtration station as an example Wastewater enters the diversion hole 13 of the fixed base 12 from the inlet pipe 14. Since the outlet of the diversion hole 13 leading to the spare filter collection box 59 is closed by the sealing plate 17, all the wastewater flows to the main filter collection box 6 through the open outlet and enters the main filter collection box 6 from its main inlet hole 7.

[0030] As the wastewater flows through the main filter collection box 6, it is filtered by the filter plate 8 inside it. Impurities are trapped in the main filter collection box 6. The filtered clean water passes through the filter plate 8 and flows into the bottom of the filter chamber. The clean water passes through the drain hole 44 at the bottom of the filter chamber, flows through the sewage pipe 45 into the manifold 46, and is finally discharged through the discharge pipe 47, completing one treatment cycle.

[0031] 3. Switching the filter channel from the main filter to the backup filter; When impurities accumulate in the main filter collection box 6 to the point where cleaning is necessary (the accumulation of impurities can be observed through the transparent plate 3), a switching operation is performed, as follows: Pulling the lever 26 upwards stretches the spring 25, causing the locking lever 24 to rise and its bottom end to disengage from the second locking groove 22 on the transmission plate 20. To the left (e.g.) Figure 4 (in the direction) pull the transmission plate 20 to move horizontally, and the transmission plate 20 slides smoothly in the groove of the bearing plate 21 through the slider.

[0032] The transmission plate 20 drives the two rectangular rods 16 and the sealing plate 17 to move synchronously via the connecting rod 19 and the vertical plate 18. As a result, the sealing plate 17 that originally closed the spare side diversion hole 13 is moved open, while the main filter side diversion hole 13 that was originally open is closed by another sealing plate 17 (e.g., Figure 3 (As shown). At this point, the water inlet channel is switched from the main filter collection box 6 to the backup filter collection box 59.

[0033] After the transmission plate 20 is moved into place, the first locking groove 27 on it moves to directly below the locking rod 24. When the pull block 26 is released, the locking rod 24 engages with the first locking groove 27 under the action of the spring 25, fixing the transmission plate 20 in a new position for the filtration station.

[0034] During the movement of the transmission plate 20, the rack 29 at its bottom drives the first gear 32, which meshes with it, to rotate. The first gear 32 drives the second gear 33, which meshes with it, to rotate in the opposite direction. The first gear 32 and the second gear 33 respectively drive the first screw 30 and the second screw 31 to rotate.

[0035] The rotation of the first screw 30 and the second screw 31 drives the two movable plates 36, which are threadedly connected to them, to move in opposite directions or away from each other along the guide rod 35, thereby causing the two baffles 37 to move.

[0036] In the new standby filter station, the baffle 37 corresponding to the standby filter collection box 59 extends and abuts against the outside of the standby filter collection box 59 to provide a lock; while the baffle 37 corresponding to the main filter collection box 6 moves outward to release the additional lock on it, in preparation for the removal and cleaning of the main filter collection box 6.

[0037] When the transmission plate 20 moves, the two opening and closing plates 58 move in conjunction with the vertical plate 18, the U-shaped plate 50, and the round rod 49. This causes the previously open main filter side drain hole 44 to close, while the previously closed standby filter side drain hole 44 opens. Thus, the drainage channel and the inlet channel simultaneously switch to the standby filter side. After the switch is complete, wastewater filtration can continue, reducing downtime.

[0038] IV. Cleaning and replacing the filter box; Remove the full tank: After the equipment switches to the standby filtration station, the main filter collection tank 6 stops receiving water. (To the right, e.g.) Figure 2 (As shown) Press the limiting plate 40 on the corresponding side of the main filter collection box 6 to compress the first reset spring 41 and retract it into the first reset groove 39, thereby releasing the limitation on the outside of the main filter collection box 6.

[0039] Pull the main filter collection box 6 outward by using handle 9. The inner slot will disengage from the card plate 10, allowing the main filter collection box 6, which is full of impurities, to be removed from the installation port 5 for cleaning.

[0040] Push the cleaned main filter collection box 6 into the installation port 5. The slot engages with the card plate 10. Release the limiting plate 40. Under the action of the first reset spring 41, the limiting plate 40 pops out and presses against the outside of the main filter collection box 6, thus completing the installation.

[0041] At this point, the cleaned main filter collection box 6 becomes the new "backup filter collection box". When the backup filter collection box 59 in use needs cleaning, repeat the above steps and reverse the operation of the switching mechanism to achieve channel switching again and uninterrupted operation of the equipment.

[0042] V. Removal of the box lid; When it is necessary to open the cover 2 to inspect or maintain the inside of the equipment, push the two push-pull plates 57 inward towards each other. The push-pull plates 57 drive the rectangular insert plate 56 to compress the second reset spring and retract into the second reset groove 55, so that its end exits from the transverse rectangular card hole 53 of the rectangular plate 52, thereby releasing the lock on the cover 2. After unlocking, the lid 2 can be lifted upwards to disengage the positioning block from the positioning slot 51, thus completing the quick disassembly of the lid 2.

The setting of the two push-pull plates 57 facilitates the movement of the two rectangular insert plates 56. The top of the sewage treatment tank 1 is provided with multiple positioning slots 51. The bottom of the tank cover 2 is fixedly installed with multiple positioning blocks. The multiple positioning blocks are respectively engaged with the multiple positioning slots 51.

[0053] Working principle: I. Initial equipment status; The filter channel switching mechanism is in its initial position, such as the main filter position. At this time, the locking rod 24 is engaged in the second locking groove 22 of the transmission plate 20 under the action of the spring 25, fixing the position of the transmission plate 20.

[0054] At this workstation, one of the sealing plates 17 seals the opening on the fixed base 12 through the diversion hole 13 leading to the side of the spare filter collection box 59, while the opening leading to the side of the main filter collection box 6 is open.

[0055] At the same time, one baffle 37 is in the extended state, restricting the main filter collection box 6 away from the partition plate 4 so that it will not easily detach, while the other baffle 37 is in the retracted state, not restricting the backup filter collection box 59.

[0056] During the main filtration station, the opening and closing plate 58 of the drain hole 44 corresponding to the filter chamber where the main filter collection box 6 is located is pulled open, and the drainage channel is opened; while the drain hole 44 corresponding to the filter chamber where the backup filter collection box 59 is located is closed by its opening and closing plate 58.

[0057] II. Wastewater filtration treatment, taking the main filtration station as an example; Wastewater enters the diversion hole 13 of the fixed base 12 from the inlet pipe 14. Since the outlet of the diversion hole 13 leading to the spare filter collection box 59 is closed by the sealing plate 17, all the wastewater flows to the main filter collection box 6 through the open outlet and enters the main filter collection box 6 from its main inlet hole 7.

[0058] As wastewater flows through the main filter collection box 6, it is filtered by the filter plate 8 inside. Impurities are trapped inside the main filter collection box 6. The filtered clean water passes through the filter plate 8 and flows into the bottom of the filter chamber. The clean water flows through the drain hole 44 at the bottom of the filter chamber, through the sewage pipe 45 into the manifold 46, and finally is discharged through the discharge pipe 47, completing one treatment cycle. When the wastewater filtered by the filter plate 8 needs to be treated again with wastewater treatment agent, the solenoid valve on the sewage pipe 45 is closed, so that the wastewater is trapped in the filter chamber. Then, wastewater treatment agent is added to the filter chamber through the wastewater treatment agent addition pipe. The wastewater is treated by the wastewater treatment agent. After treatment, the solenoid valve is opened to discharge the wastewater.

[0059] 3. Switching the filter channel from the main filter to the backup filter; When impurities accumulate in the main filter collection box 6 to the point where cleaning is necessary (the accumulation of impurities can be observed through the transparent plate 3), a switching operation is performed, as follows: Pulling the lever 26 upwards stretches the spring 25, causing the locking lever 24 to rise and its bottom end to disengage from the second locking groove 22 on the transmission plate 20. To the left (e.g.) Figure 4 (in the direction) pull the transmission plate 20 to move horizontally, and the transmission plate 20 slides smoothly in the groove of the bearing plate 21 through the slider.

[0060] The transmission plate 20 drives the two rectangular rods 16 and the sealing plate 17 to move synchronously via the connecting rod 19 and the vertical plate 18. As a result, the sealing plate 17 that originally closed the spare side diversion hole 13 is moved open, while the main filter side diversion hole 13 that was originally open is closed by another sealing plate 17 (e.g., Figure 3 (As shown). At this point, the water inlet channel is switched from the main filter collection box 6 to the backup filter collection box 59.

[0061] After the transmission plate 20 is moved into place, the first locking groove 27 on it moves to directly below the locking rod 24. When the pull block 26 is released, the locking rod 24 engages with the first locking groove 27 under the action of the spring 25, fixing the transmission plate 20 in a new position for the filtration station.

[0062] During the movement of the transmission plate 20, the rack 29 at its bottom drives the first gear 32, which meshes with it, to rotate. The first gear 32 drives the second gear 33, which meshes with it, to rotate in the opposite direction. The first gear 32 and the second gear 33 respectively drive the first screw 30 and the second screw 31 to rotate.

[0063] The rotation of the first screw 30 and the second screw 31 drives the two movable plates 36, which are threadedly connected to them, to move in opposite directions or away from each other along the guide rod 35, thereby causing the two baffles 37 to move.

[0064] In the new standby filter station, the baffle 37 corresponding to the standby filter collection box 59 extends and abuts against the outside of the standby filter collection box 59 to provide a lock; while the baffle 37 corresponding to the main filter collection box 6 moves outward to release the additional lock on it, in preparation for the removal and cleaning of the main filter collection box 6.

[0065] When the transmission plate 20 moves, the two opening and closing plates 58 move in conjunction with the vertical plate 18, the U-shaped plate 50, and the round rod 49. This causes the previously open main filter side drain hole 44 to close, while the previously closed standby filter side drain hole 44 opens. Thus, the drainage channel and the inlet channel simultaneously switch to the standby filter side. After the switch is complete, wastewater filtration can continue, reducing downtime.

[0066] IV. Cleaning and replacing the filter box; Remove the full tank: After the equipment switches to the standby filtration station, the main filter collection tank 6 stops receiving water. (To the right, e.g.) Figure 2 (As shown) Press the limiting plate 40 on the corresponding side of the main filter collection box 6 to compress the first reset spring 41 and retract it into the first reset groove 39, thereby releasing the limitation on the outside of the main filter collection box 6.

[0067] Pull the main filter collection box 6 outward by using handle 9. The inner slot will disengage from the card plate 10, allowing the main filter collection box 6, which is full of impurities, to be removed from the installation port 5 for cleaning.

[0068] Push the cleaned main filter collection box 6 into the installation port 5. The slot engages with the card plate 10. Release the limiting plate 40. Under the action of the first reset spring 41, the limiting plate 40 pops out and presses against the outside of the main filter collection box 6, thus completing the installation.

[0069] At this point, the cleaned main filter collection box 6 becomes the new "backup filter collection box". When the backup filter collection box 59 in use needs cleaning, repeat the above steps and reverse the operation of the switching mechanism to achieve channel switching again and uninterrupted operation of the equipment.

[0070] V. Removal of the box lid; When it is necessary to open the cover 2 to inspect or maintain the inside of the equipment, push the two push-pull plates 57 inward towards each other. The push-pull plates 57 drive the rectangular insert plate 56 to compress the second reset spring and retract into the second reset groove 55, so that its end exits from the transverse rectangular card hole 53 of the rectangular plate 52, thereby releasing the lock on the cover 2. After unlocking, the lid 2 can be lifted upwards to disengage the positioning block from the positioning slot 51, thus completing the quick disassembly of the lid 2.

[0071] Example 3: The difference from Example 1 is that an electric push rod replaces the second locking groove 22, mounting block 23, locking rod 24, spring 25, pull block 26, and first locking groove 27. The electric push rod is fixedly installed on the bottom of the support plate 21, and a transmission block is fixedly installed on the output shaft of the electric push rod. One side of the transmission block is fixedly connected to the transmission plate 20. When the impurities in the main filter collection box 6 accumulate to the point where cleaning is required (the accumulation of impurities can be observed through the transparent plate 3), a switching operation is performed, as follows: The electric push rod drives the transmission block to move, which in turn drives the transmission plate 20 to move horizontally. The transmission plate 20 then slides smoothly in the groove of the support plate 21 via a slider.

[0072] The transmission plate 20 drives the two rectangular rods 16 and the sealing plate 17 to move synchronously via the connecting rod 19 and the vertical plate 18. As a result, the sealing plate 17 that originally closed the spare side diversion hole 13 is moved open, while the main filter side diversion hole 13 that was originally open is closed by another sealing plate 17 (e.g., Figure 3 (As shown). At this point, the water inlet channel is switched from the main filter collection box 6 to the backup filter collection box 59.

[0073] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
