Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a movable air conditioner unit. Background Art

[0002] Air conditioners can be categorized into many types based on their technical principles and application scenarios. Portable air conditioners, also known as mobile air coolers, are designed with universal wheels, allowing them to be moved to any location. These air conditioners are equipped with a water curtain, which forms a uniform film of water. When hot air passes through the damp curtain, the water evaporates, absorbing heat from the air and achieving physical cooling.

[0003] The patent document with announcement number CN218627092U discloses an integrated unit mobile air conditioner; it includes a cabinet, a first fan, a second fan, and a condenser, a compressor, an evaporator and an expansion valve that are cyclically connected; the interior of the cabinet is provided with a separated upper cavity and a lower cavity, the first fan is installed in the upper cavity, the front side wall of the upper cavity is provided with an air outlet directly opposite to the first fan, the remaining three side walls of the upper cavity are provided with air inlet holes and the inner side surfaces of the three side walls are respectively provided with a first water curtain; the cross-sectional shape of the evaporator and the cross-sectional shape of the condenser are both concave, the evaporator is installed in a refrigeration cavity surrounded by three first water curtains and the first fan, and the three side walls of the evaporator are respectively opposite to the three first water curtains, and the first fan works, so that the air outside the cabinet flows through the air inlet hole, the first water curtain, the evaporator and the first fan and is discharged from the air outlet.

[0004] However, this solution also presents the following issues: In addition to cooling the flowing air, the water curtain's honeycomb structure also absorbs pollutants such as dust and odors, delivering clean air. A filter is also required to intercept large particles of pollutants. The filter and the water curtain work together to achieve efficient dust removal and other operations. However, after intercepting impurities, the filter tends to clog its pores, reducing evaporation efficiency and affecting the air cooling efficiency, necessitating disassembly and frequent cleaning. Summary of the Invention

[0005] The present invention provides a movable air-conditioning unit, aiming to solve the problem in the related art that a filter screen is easily clogged and needs to be frequently disassembled for cleaning.

[0006] The movable air-conditioning unit of the present invention includes a water curtain and a filter screen arranged in a body, and a water tank, a control component, a cleaning frame, and a winding component are arranged in the body; the water tank is located below the water curtain, and a sewage pipe connected to the water tank is provided on the side of the body, and the control component is arranged in the water tank to control the closing of the sewage pipe. The cleaning frame is assembled in the water tank for sliding left and right, and the top of the cleaning frame abuts against the side of the filter screen. The winding component is connected to the end of the filter screen to drive the filter screen to move left and right above the cleaning frame; initially, the sewage pipe is closed, and the cleaning frame and the part of the filter screen that cooperates with the cleaning frame are immersed in water; when the filter screen moves to the left, the cleaning frame cooperates with the water in the water tank to clean the filter screen; when moving to the right, the filter screen drives the cleaning frame to move right and cooperate with the control component to open the sewage pipe to discharge the water and impurities in the water tank through the sewage pipe.

[0007] The effect is that, during normal operation, air passes through the filter and the water curtain in sequence, impurities in the air are filtered when passing through the filter, and the air is cooled when passing through the water curtain. At the same time, the water curtain needs to be continuously ventilated during operation. When the filter needs to be cleaned, the water tank is filled with water so that the filter abutting the top of the cleaning frame is immersed in the water. Then, the reel assembly drives the filter to move left, so that the cleaning frame sequentially cooperates with different positions of the filter to scrape off impurities on the filter. At the same time, the filter is always immersed in water. The water can cooperate with the cleaning frame to clean the filter. When the filter moves to the right, the cleaning frame is driven to move right by friction and cooperates with the control assembly to open the drain pipe, and then impurities and water are discharged through the drain pipe. In addition, when draining, water can be continuously ventilated into the water curtain, and the filter is flushed by the water flowing out from under the water curtain, thereby improving the cleaning effect of the filter and reducing the frequency of removing the filter to achieve rapid cleaning of the filter.

[0008] Preferably, the water tank includes a connecting part, a middle part, and a placement part. The connecting part is located below the middle part, the placement part is located on the left side of the middle part, the sewage pipe is connected to the connecting part, and a water outlet pipe connected to the middle part is provided on the machine body. The water flowing out from below the water curtain is discharged through the middle part and the water outlet pipe. When cleaning the filter screen, the water outlet pipe is blocked to increase the water storage capacity in the water tank so that the cleaning frame is located below the water level, and the control component is arranged between the middle part and the connecting part.

[0009] During normal operation, the outlet pipe is open, allowing water from the bottom of the water curtain to flow into the middle section before draining out through the outlet pipe. This water can be recycled. When cleaning the filter, the outlet pipe is closed, allowing the water level in the tank to be above the cleaning frame. As the cleaning frame moves to the right, it cooperates with the control assembly to connect the middle section with the connecting section, opening the drain pipe and draining impurities and water containing them. This prevents wastewater generated during cleaning from entering the circulation system and reduces clogging of the water curtain.

[0010] Preferably, a slide groove is provided on the side wall of the water tank, and the control assembly includes a control panel and a spring member. The control panel is assembled in the slide groove for sliding left and right, and the spring member is arranged in the slide groove and connected to the control panel. The spring member drives the control panel to slide between the middle part and the connecting part. When the control panel slides completely between the middle part and the connecting part, the sewage pipe is in a closed state.

[0011] The spring drives the control plate to move to abut against the inner wall of the water tank, separating the middle part from the connecting part, so that the sewage pipe is in a closed state. When the cleaning frame moves above the connecting part, it drives the control plate to move into the slide groove, connecting the middle part with the connecting part, and opening the sewage pipe.

[0012] Preferably, the cleaning frame slides left and right within the placement portion and the middle portion, a push rod is provided on the cleaning frame, and a baffle is provided on the side of the control panel facing away from the elastic member, the push rod and the baffle are arranged in the same horizontal direction, and when the cleaning frame moves to the right, the push rod and the baffle cooperate to drive the control panel to move to open the sewage pipe.

[0013] When the cleaning frame moves to the right, the push rod moves accordingly, and the push rod moves to abut against the stop rod, and the control plate is driven by the stop rod to move into the chute, thereby controlling the closing of the sewage pipe.

[0014] Preferably, the cleaning frame includes a plurality of scrapers arranged in a left-right arrangement, and the heights of the plurality of scrapers gradually increase in a direction away from the control assembly.

[0015] By providing a plurality of scrapers of different heights, the force of each scraper contacting the filter is gradually increased. The scraping force applied to the filter is gradually increased each time the filter passes through a scraper, thereby improving the cleaning effect of the filter.

[0016] Preferably, two groups of winding components are arranged at intervals corresponding to the upper and lower ends of the water curtain, and the winding components are located on one side of the water curtain. The two ends of the filter screen respectively bypass the upper and lower ends of the water curtain and are connected to the winding components.

[0017] Two groups of winding components are provided, and the two groups of winding components are arranged up and down, one group of winding components winds up the filter net, and the other group unfolds the filter net, and the two groups of winding components cooperate alternately to drive the filter net to move back and forth.

[0018] Preferably, an installation frame is assembled in the machine body for sliding up and down, the water curtain is installed in the installation frame, a pushing member is provided in the machine body, the output end of the pushing member is connected to the installation frame to drive the installation frame to move up and down, a pressing part is provided at the bottom of the installation frame, the pressing part is arranged in the horizontal direction, the installation frame moves downward, and the pressing part presses the filter screen to make it abut against the cleaning frame, while driving the filter screen to be immersed in water.

[0019] The pushing member drives the installation frame to move downward, and the installation frame drives the pressing part to move downward, and the pressing part drives the filter screen below it to abut against the cleaning frame, so that the filter screen passing under the pressing part can abut against the cleaning frame, so that the filter screen can be cleaned through the cleaning frame.

[0020] Preferably, the cleaning frame also includes a mounting frame, and the scraper and the push rod are both mounted on the mounting frame. A through groove for impurities to pass through is formed between two adjacent scrapers. When the scraper is in the placement portion, the bottom of the scraper slides and abuts against the bottom wall of the placement portion.

[0021] When the filter screen passes through the scraper, the scraper scrapes off the impurities on the filter screen, and the scraped impurities enter the through groove. When the scraper moves to the top of the connecting part, the impurities in the scraper pass through the bottom of the scraper and enter the connecting part, so that the impurities can be discharged and collected.

[0022] Preferably, a plurality of openings are provided on the side of the installation frame, the openings passing through the installation frame from left to right and evenly distributed on the installation frame, and the flowing air contacts the water curtain through the openings.

[0023] The circulating air enters the installation frame through the openings and contacts the water film on the water curtain. At the same time, multiple openings are evenly distributed, so that the flowing gas contacts the water curtain more fully, ensuring the cooling effect on the circulating gas.

[0024] Preferably, a water outlet is provided at the bottom of the installation frame, the water outlet is communicated with the interior of the installation frame, a water curtain is located above the water outlet, and water in the water curtain flows out through the bottom of the water curtain and the water outlet.

[0025] Water enters the water curtain through the top of the water curtain, and finally flows out through the outlet at the bottom of the water curtain to rinse the filter.

[0026] Beneficial effects: 1. The present invention sets a cleaning frame under the filter screen. When the winding assembly drives the filter screen to move to the left, it passes through the cleaning frame and scrapes off impurities adhered to the filter screen. When the winding assembly drives the filter screen to move to the right, it cooperates with the control panel to push the control panel to move and open the drain pipe, so that impurities in the water tank and water containing impurities are discharged from the drain pipe. At the same time, the water flowing out from the bottom of the water curtain is used to backwash the filter screen, thereby realizing the cleaning of the filter screen without disassembling, reducing the difficulty of cleaning operation, and facilitating the cleaning of the filter screen.

[0027] 2. A sewage pipe is installed on the machine body, connecting to the connecting section and a drain pipe to the middle section. During normal operation, water flowing out from below the water curtain enters the middle section and then flows out through the outlet pipe. When cleaning the filter, the outlet pipe is closed. As the filter moves to the left, the scraper cooperates with the water in the water tank to scrape impurities from the filter and clean it at the same time. As the filter moves to the right, the drain pipe is opened, and impurities and water are discharged through the drain pipe. The circulating water circulates only through the outlet pipe, and water containing impurities is discharged through the drain pipe. The two are treated separately, reducing the possibility of impurities from cleaning entering the water curtain, thereby reducing the possibility of clogging the water curtain.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 8 As shown, the movable air conditioning unit of the present invention includes a body 1, a water curtain 2, and a filter 3 disposed within the body 1. Universal wheels 16 are provided at the bottom of the body 1, allowing the body 1 to be moved and placed in a desired location for operation. An air inlet 11 and an air outlet 12 are provided on either side of the body 1, with the air outlet 12 on the left side of the body 1 and the air inlet 11 on the right side. The air inlet 11 and the air outlet 12 are arranged in the same horizontal direction. The water curtain 2 and the filter 3 are disposed between the air inlet 11 and the air outlet 12, with the filter 3 disposed on the side of the water curtain 2 closest to the air inlet 11. Airflow enters the body 1 through the air inlet 11, passes through the filter 3 and the water curtain 2 in sequence, and is discharged through the air outlet 12. As the airflow passes through the water curtain 2, it is cooled by the water curtain 2.

[0039] Reference Figure 2 、 Figure 3 、 Figure 5 The body 1 is equipped with a water tank 4, a control component 5, a cleaning frame 6, and a reel assembly 7. The water tank 4 is located below the water curtain 2. Water flowing out from the bottom of the water curtain 2 can enter the water tank 4 and be collected or discharged through the water tank 4. The reel assembly 7 is connected to the filter 3 to drive the filter 3 to move. The cleaning frame 6 is slidably assembled in the water tank 4. The cleaning frame 6 slides left and right in the water tank 4, and the top of the cleaning frame 6 slides against the filter 3. A sewage pipe 13 is provided on the body 1 and is connected to the water tank 4. The control component 5 is arranged in the water tank 4 to control the closure of the sewage pipe 13.

[0040] When the filter 3 needs to be cleaned, the control assembly 5 closes the drain pipe 13, filling the water tank 4 with water until the cleaning frame 6 is completely below the water level. At this time, the portion of the filter 3 in contact with the cleaning frame 6 is immersed in the water in the water tank 4. The reel assembly 7 drives the filter 3 to move leftward, causing various parts of the filter 3 to move past the cleaning frame 6. The cleaning frame 6 scrapes away impurities on the filter 3, and at the same time, the water in the water tank 4 cleans the filter 3.

[0041] Then, the reel assembly 7 drives the filter 3 to move rightward. Since the filter 3 contacts the cleaning frame 6, it drives the cleaning frame 6 to move rightward until the cleaning frame 6 cooperates with the control assembly 5 to open the drain pipe 13. At this time, the water in the water tank 4 and the cleaned impurities are discharged through the drain pipe 13. At the same time, when the drain pipe 13 is opened, the reel assembly 7 drives the filter 3 to move, and at the same time, water is passed into the water curtain 2. The water flows out from the bottom of the water curtain 2 to rinse the filter 3, further improving the cleaning effect of the filter 3.

[0042] Reference Figure 3 、 Figure 4 The water tank 4 includes a connecting portion 41, an intermediate portion 42, and a placement portion 43. The connecting portion 41, the intermediate portion 42, and the placement portion 43 are interconnected. The connecting portion 41 is located below the intermediate portion 42, and the placement portion 43 is located to the left of the intermediate portion 42. The sewage pipe 13 is connected to the connecting portion 41. The water outlet pipe 14 is provided on the body 1 and is connected to the intermediate portion 42. In other words, the water outlet pipe 14 is located above the sewage pipe 13. The control component 5 is disposed between the intermediate portion 42 and the connecting portion 41. When the control component 5 isolates the intermediate portion 42 from the connecting portion 41, the sewage pipe 13 is in a closed state.

[0043] During normal operation, the control assembly 5 separates the middle portion 42 from the connecting portion 41. At this time, water cannot enter the drain pipe 13 through the connecting portion 41, that is, the drain pipe 13 is in a closed state. The outlet pipe 14 is in an open state, and the flowing air is discharged through the water curtain 2. At the same time, water is continuously passed into the water curtain 2. The water passes through the bottom of the water curtain 2 and enters the middle tank, and then is discharged through the outlet pipe 14. A circulation pipe connected to the outlet pipe 14 can be set on the outside of the body 1. The discharged water enters the circulation pipe and finally enters the water curtain 2 again, so that the water is recycled.

[0044] When the filter 3 needs to be cleaned, the outlet pipe 14 is closed, and the water level in the water tank 4 gradually increases. When the water level in the water tank 4 is full, the water flow into the water curtain 2 is stopped. The filter 3 is then moved by the winding assembly 7 to clean it. When the winding assembly 7 drives the filter 3 to move to the right, it drives the cleaning frame 6 to move to cooperate with the control assembly 5. The control assembly 5 controls the middle part 42 to be connected with the connecting part 41, so that the water in the water tank 4 is discharged through the connecting part 41 and the drain pipe 13. At the same time, water is passed into the water curtain 2 again, and the water used for backwashing is also discharged through the drain pipe 13. By setting the control assembly 5, impurities and water containing impurities can be discharged separately, so as to prevent water containing impurities from entering the circulation and reduce the phenomenon of clogging of the water curtain 2.

[0045] Reference Figure 2 、 Figure 3A chute 411 is provided on the sidewall of the water tank 4, i.e., the chute 411 is disposed between the middle portion 42 and the connecting portion 41. The control assembly 5 includes a control panel 51 and a spring 52. The control panel 51 is slidably mounted within the chute 411 and slides left and right within the chute 411, i.e., the control panel 51 and the cleaning frame 6 slide in the same direction. The spring 52 is disposed within the chute 411 and is configured as a spring. The spring is arranged along the sliding direction of the control panel 51. One end of the spring 52 is connected to the inner wall of the chute 411, and the other end is connected to the control panel 51. The spring 52 drives the control panel 51 toward the outside of the chute 411, causing the control panel 51 to abut against the inner wall of the water tank 4, thereby isolating the middle portion 42 from the connecting portion 41. When the cleaning frame 6 slides rightward, it drives the control panel 51 to move, thereby opening the sewage pipe 13.

[0046] Reference Figure 5 、 Figure 6 The cleaning frame 6 is disposed within the placement portion 43 and the middle portion 42, and slides left and right between the placement portion 43 and the middle portion 42. A push rod 8 is disposed at the bottom of the cleaning frame 6, and a stop rod 81 is disposed on the side of the control panel 51 facing away from the elastic member 52. The push rod 8 and the stop rod 81 are disposed in the same horizontal direction. Initially, the cleaning frame 6 is located within the placement portion 43. When the filter 3 moves in the opposite direction, the cleaning frame 6 is driven to move rightward toward the control panel 51, simultaneously driving the push rod 8 and the stop rod 81 to cooperate. The cleaning frame 6 continues to move, and the push rod 8 and the stop rod 81 drive the control panel 51 to move, while compressing the elastic member 52 to adjust the position of the control panel 51. After the filter 3 is cleaned, the filter 3 drives the cleaning frame 6 back into the placement portion 43. The push rod 8 separates from the stop rod 81, and the elastic member 52 drives the control panel 51 to move to its position, thereby closing the sewage pipe 13 again.

[0047] Reference Figure 3 、 Figure 5 、 Figure 6 The cleaning frame 6 includes: a mounting frame 61 and a scraper 62. The push rod 8 is installed on the mounting frame 61. A plurality of scrapers 62 are arranged on the left and right sides of the mounting frame 9 at intervals, so that a through groove 621 for impurities to pass through is formed between every two scrapers 62. The lower end of the scraper 62 slides with the bottom wall of the placement portion 43, and the upper end of the scraper 62 abuts against the filter screen 3.

[0048] When the filter 3 moves to the left, the scraper 62 scrapes off impurities on the filter 3, and the scraped impurities enter the through groove 621. At this time, the scraper 62 is located in the placement groove, and the impurities are temporarily stored in the through groove 621. When the filter 3 moves to the right, the scraper 62 moves above the connecting portion 41. After the sewage pipe 13 is opened, the impurities in the through groove 621 flow downward with the water flow, so that the impurities are quickly discharged.

[0049] Reference Figure 3 、 Figure 5 、 Figure 6 The scrapers 62 are arranged in a vertical direction, and their height gradually increases as they move away from the control assembly 5. That is, the height of the multiple scrapers 62 gradually increases from right to left, and the lower ends of the multiple scrapers 62 are located in the same horizontal direction. The multiple scrapers 62 all abut against the filter 3. By setting the scrapers 62 at different heights, the abutment force between the scrapers 62 and the filter 3 gradually increases. As the filter 3 moves, the scrapers 62 of different heights sequentially clean the filter 3 to varying degrees, thereby improving the cleaning effect of the filter 3. In addition, the upper ends of the scrapers 62 are pointed to reduce the contact area between the scrapers 62 and the filter 3, thereby improving the cleaning effect of the filter 3.

[0050] Reference Figure 2 、 Figure 3 、 Figure 5 Two reel assemblies 7 are provided, each connected to one end of the filter screen 3. While one reel assemblies 7 reels the filter screen 3, the other reel assemblies 7 unroll it. The two reel assemblies 7 operate alternately, driving the filter screen 3 back and forth. The reel assemblies 7 are located on the left side of the water curtain 2. The ends of the filter screen 3 are connected to the reel assemblies 7, bypassing the upper and lower ends of the water curtain 2. This ensures that when the filter screen 3 is reeled in, it passes through the cleaning frame 6 located at the bottom of the water curtain 2.

[0051] Reference Figure 2 、 Figure 3 、 Figure 5 The reel assembly 7 includes a housing 71, a reel shaft, and a motor. The housing 71 is mounted within the machine body 1, and the reel shaft and motor are respectively mounted on the housing 71 (the reel shaft and motor are not shown in the figure). The reel shaft is rotatably mounted within the housing 71. An opening is provided on the side of the housing 71, through which the end of the filter 3 is wound around the reel shaft. The output end of the motor extends into the housing 71 and is fixedly connected to the reel shaft via a coupling. When cleaning the filter 3, the motors in the two reel assemblies 7 operate synchronously and drive the reel shafts to rotate in opposite directions. That is, while one reel shaft is reeling in the filter 3, the other reel shaft is unreeling the filter 3, thereby enabling the filter 3 to move through the cleaning frame.

[0052] In addition, a spare filter 3 can be wound on one of the reels. That is, the length of the filter 3 is much longer than the length required for filtration. If the filtration effect is still not effectively improved after cleaning the filter 3, the part of the filter 3 can be reeled up by the reel, and the spare filter 3 on the other reel can be unfolded and pulled to the side of the water curtain 2, and the spare filter 3 can be used for filtration. This can reduce the frequency of disassembly and replacement of the filter 3.

[0053] Reference Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 A mounting frame 9 is provided within the housing 1. The mounting frame 9 slides vertically within the housing 1 and is positioned perpendicular to the direction of air flow. The water curtain 2 is mounted within the mounting frame 9. A pusher 91 is provided within the housing 1. The pusher 91 is configured as a cylinder, and the piston rod of the cylinder is connected to the mounting frame 9. That is, the output end of the pusher 91 is connected to the mounting frame 9 to drive the mounting frame 9 to move up and down. A pressing portion 92 is provided at the bottom of the mounting frame 9. The pressing portion 92 is arranged in a horizontal direction. The filter screen 3 is connected to the winding assembly 7 through the bottom of the pressing portion 92. The pressing portion 92 is located above the cleaning frame 6.

[0054] When the filter 3 needs to be cleaned, the pusher 91 drives the mounting frame 9 to move downward, and the mounting frame 9 presses the filter 3 downward via the pressing portion 92, causing the filter 3 to abut against the upper end of the cleaning frame 6. Simultaneously, when the filter 3 needs to be cleaned, the filter 3 is pressed downward to prevent the filter 3 from being continuously immersed in water due to water in the water tank 4. Furthermore, the pressing portion 92 can be made of a flexible rubber material to prevent damage to the filter 3 due to excessive force when the pressing portion 92 presses the filter 3. Simultaneously, the pressing portion 92 is made of a flexible material, which can drive the filter 3 to abut against the upper ends of multiple scrapers 62 simultaneously, thereby improving the cleaning effect of the filter 3.

[0055] In addition, the water curtain 2 moves up and down through the mounting frame 9. During the process, the mounting frame 9 supports the water curtain 2, reduces the deformation of the water curtain 2, ensures its contact area with the flowing air, and ensures the cooling effect on the flowing air.

[0056] Reference Figure 7 、 Figure 8 A plurality of openings 93 are provided on the side of the mounting frame 9. The openings 93 pass through the mounting frame 9 on the left and right, and are evenly distributed on the mounting frame 9, so that the flowing air can evenly contact the water film formed on the water curtain 2 through the openings 93, thereby improving the cooling effect.

[0057] In other embodiments, the opening 93 may be divided into opening 931 and opening 932, both of which are evenly distributed on the mounting frame 9, and are staggered. This allows the flowing air to enter the mounting frame 9 through opening 931 and come into contact with the water curtain 2, and then change its path before being discharged through opening 932, thereby increasing the air flow path within the mounting frame 9. Furthermore, at the same air flow rate, the contact time between the air and the water curtain 2 is increased, thereby improving the cooling effect on the flowing air.

[0058] Reference Figure 7 、 Figure 8A water outlet 94 is provided at the bottom of the mounting frame 9, extending along the length of the scraper 62. The water outlet 94 communicates with the interior of the mounting frame 9. The water curtain 2 is located above the water outlet 94. A water inlet pipe 21 is provided above the water curtain 2 and communicates with the interior of the water curtain 2. The water inlet pipe 21 communicates with the water outlet pipe 14 via a circulation pipe, enabling water recycling. Water flows through the water curtain 2 and is discharged through the water outlet 94. When cleaning the filter 3, the water can be flushed to remove impurities within the filter pores, improving the cleaning effect of the filter 3.

[0059] Reference Figure 1 A fan 15 is provided in the body 1, and the fan 15 is provided on one side of the water curtain 2. A channel for air flow is provided in the body 1, and the fan 15 is assembled in the channel. The fan 15 drives the air flow to flow in the channel through the channel.

[0060] The implementation principle of the present invention is: During normal operation, the control panel 51 abuts against the inner wall of the chute 411 , and the middle portion 42 is separated from the connecting portion 41 . At this time, the sewage pipe 13 is closed, and the water outlet pipe 14 is opened to flow water into the water curtain 2 . The water is then discharged through the bottom of the water curtain 2 into the middle portion 42 and finally discharged through the water outlet pipe 14 .

[0061] To clean the filter 3, close the water outlet pipe 14, allowing the water tank 4 to fill with water until the water level is above the scraper 62. Then, the pusher 91 drives the mounting frame 9 downward. The mounting frame 9, through the pressing portion 92, drives the filter 3 below the pressing portion 92 into contact with the top of the scraper 62. At this point, both the scraper 62 and the filter 3 below the pressing portion 92 are immersed in water.

[0062] Then the winding assembly 7 drives the filter screen 3 below the pressing portion 92 to move to the left. When the filter screen 3 moves past the scraper 62, the scraper 62 scrapes off the impurities on the filter screen 3. At the same time, the filter screen 3 is cleaned under the action of the water in the water tank 4.

[0063] Then the reel assembly 7 drives the filter 3 to move to the right, and the filter 3 drives the scraper 62 and the mounting bracket 61 to move to the right, and at the same time drives the push rod 8 to move to the right, and then the push rod 8 cooperates with the stop rod 81. When the scraper 62 moves to the top of the connecting portion 41, the push rod 8 drives the control plate 51 to move into the chute 411 through the stop rod 81. At this time, the middle portion 42 is connected to the connecting portion 41, and the drain pipe 13 is opened. The impurities and water containing impurities in the water tank 4 are discharged through the drain pipe 13. At the same time, the water curtain 2 continues to flow, and the water is discharged from the bottom of the water curtain 2 to rinse the filter 3. Through the above cleaning process, the filter 3 can be cleaned without disassembling, and the replacement frequency of the filter 3 is reduced. When the scraper 62 cleans the filter 3, it can be cleaned by water to improve the cleaning effect of the filter 3.

[0064] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
