[0002] When the air conditioner filter is installed on the produced air conditioner, it is necessary to clean the air conditioner filter stacked on the site to avoid the accumulation of dust and bacteria due to long-term stacking of the air conditioner filter. To prevent dust or bacteria from entering the air conditioner interior during operation, it is necessary to clean the filter of the air conditioner indoor unit before installation.

[0003] The patent with the application number CN201410663169.5 discloses an air conditioner filter screen cleaning device, which includes a motor, a water tank, and a rotating shaft arranged on the water tank. Annular brackets are arranged at both ends of the rotating shaft, and spring clips for fixing the filter screen are arranged on the circular brackets. A cross bar is arranged above the water tank, and a soft brush is arranged on the cross bar; a drain valve is arranged below the water tank. During cleaning, cleaning water, a cleaning agent, and a bactericide are first placed in the water tank. The air conditioner filter screen is fixed by the annular bracket and the spring clip, and the motor is used to drive the filter screen to rotate. The rotating filter screen contacts the soft brush, thereby realizing the cleaning of the filter screen. The contact frequency between the soft brush and the filter screen is high, the contact surface is complete, and the cleaning force is strong, so that the dirt on the filter screen can be thoroughly removed and bacteria can be killed; and after cleaning, the sewage is discharged from the drain valve, and then clean water is added to quickly clean the filter screen; the cleaning is convenient and time-consuming is short.

[0004] This patent still has the problem that the flushing range is limited, resulting in some areas outside the air conditioner filter not being flushed. Therefore, it is very necessary to design a non-dead-angle automatic cleaning device for air conditioner filter processing that can change the flushing angle and increase the flushing range. Summary of the Invention

[0005] The purpose of the present invention is to provide a non-dead-angle automatic cleaning device for air conditioner screen processing to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A dead-angle-free automatic cleaning device for air-conditioning screen processing, including a bottom shell, the top of the bottom shell is fixedly connected to an upper shell, the inner top of the bottom shell is fixedly connected to a support frame, the side of the upper shell is fixedly connected to a driving motor, and a flushing and cleaning assembly is arranged inside the upper shell. The flushing and cleaning assembly includes a horizontally arranged sliding rod, a sliding plate, a threaded rod, a gear bar, a coaxial gear, a rotating handle, a peristaltic tube, a connecting vibration rod, a knocking tooth block, a deflecting block, a spray head, and a retaining tooth block. The horizontally arranged sliding rod is fixedly connected to the inner side surface of the upper shell, the sliding plate is slidably connected to the outside of the horizontally arranged sliding rod, the threaded rod is rotatably connected to the inside of the upper shell, the gear bar is rotatably connected to the bottom surface of the sliding plate, the coaxial gear is rotatably connected to the surface of the support frame, the rotating handle is fixedly connected to the upper surface of the coaxial gear, the peristaltic tube is arranged outside the rotating handle, the connecting vibration rod is fixedly connected to the inside of the upper shell, the knocking tooth block is fixedly connected to the side surface of the connecting vibration rod, the deflecting block is rotatably connected to the outer top of the peristaltic tube, the spray head is fixedly connected to the inside of the deflecting block, the retaining tooth block is fixedly connected to the surface of the support frame, the peristaltic tube is fixedly connected to the sliding plate, one end of the peristaltic tube bypasses the outside of the rotating handle, and the part bypassing the peristaltic tube is a rubber tube, and the peristaltic tube at the top part of the sliding plate is a metal tube. The peristaltic tube is rotatably connected to the deflecting block, the spray head is communicated with the peristaltic tube, the deflecting block is slidably connected to the connecting vibration rod, the retaining tooth block is in contact with the gear bar, and the gear bar is made of an elastic material. When the driving motor is in a working state, the rotation of the threaded rod is driven by the operation of the driving motor to drive the sliding plate to slide along the horizontally arranged sliding rod. While the sliding plate moves, it will drive the gear bar connected to the bottom side to move along the retaining tooth block. The gear bar blocked by the retaining tooth block will deform and slide along the retaining tooth block. Subsequently, the movement of the retaining tooth block will engage with the side surface of the coaxial gear and drive the upper rotating handle to rotate, so that the rotating handle rotates to peristalsis the hose at the bottom part of the peristaltic tube, and the liquid inside the bottom shell is vertically pumped into the deflecting block connected to the top of the peristaltic tube and the spray head inside, so that the liquid sprays out from the end of the spray head to flush the air-conditioning filter screen inside the bottom shell, thereby flushing the dust on the air-conditioning flat filter screen clean. At the same time, during the movement of the sliding plate, it will contact the knocking tooth block on the side surface of the connecting vibration rod and cause a slight vibration of the liquid inside the upper shell to assist in cleaning. In addition, the movement of the sliding plate will drive the movement of the metal tube part of the peristaltic tube at the top. The movement of the peristaltic tube drives the outer deflecting block to slide on the side surface of the connecting vibration rod, so that the spraying range of the spray head is changed during the movement of the sliding plate, thereby improving the flushing effect.

[0007] According to the above technical solution, a cleaning and positioning structure is provided at the end of the threaded rod. The cleaning and positioning structure includes a short-axis connecting wheel, a short-axis hinge rod, a fixed connecting rod, a cleaning brush plate, a fixed plate bottom plate, and a rubber fixing strip. The short-axis connecting wheel is fixedly connected to the rear end of the threaded rod. The short-axis hinge rod is rotatably connected to the inside of the short-axis connecting wheel. The fixed connecting rod is rotatably connected to the top of the short-axis hinge rod. The rubber fixing strips are evenly distributed inside the upper shell. A convex fixing strip is fixedly connected to the inside of the rubber fixing strip. Side brush fixing plates are provided on both sides of the rubber fixing strip. The cleaning brush plate is fixedly connected to the inner side of the side brush fixing plate. The fixed plate bottom plate is fixedly connected to the bottom end of the cleaning brush plate. The short-axis connecting wheel is composed of two wheel disks connected by an eccentric short axis. The short-axis hinge rod is rotatably connected to the eccentric short axis. The rubber fixing strip is fixedly connected to the inner wall of the upper shell. The rubber fixing strip is slidably connected to the side brush fixing plate. When the threaded rod rotates or reverses through the driving motor, it will drive the short-axis connecting wheel connected to the threaded rod to rotate. During the rotation of the short-axis connecting wheel, the eccentric short axis inside drives the short-axis hinge rod to push the fixed connecting rod to move up and down reciprocally. Thus, the fixed connecting rod drives the connected side brush fixing plate to move up and down, making the cleaning brush plate inside the side brush fixing plate contact both sides of the air-conditioning filter. Along with the movement of the side brush fixing plate, the cleaning brush plate cleans the side of the air-conditioning filter. At the same time, by inserting the air-conditioning filter into the rubber fixing strips on both sides and using the resilience of the rubber material, the convex fixing strips in the rubber fixing strips clamp and fix the edge of the air-conditioning filter, stretching and positioning the air-conditioning filter from the arc shape, thereby improving the cleaning effect of the air-conditioning filter.

[0008] According to the above technical solution, a filtering structure is provided inside the bottom shell. The filtering structure includes a linkage rod, a fixed rod cross plate, an elastic sliding rod, a pressing filter plate, an inclined guide plate, a collection tank, and a discharge port. The linkage rod is fixedly connected to the bottom surface of the fixed plate bottom. The fixed rod cross plate is fixedly connected to the bottom end of the linkage rod. The elastic sliding rod is fixedly connected to the side surface of the fixed rod cross plate. The pressing filter plate is slidably connected to the outside of the elastic sliding rod. The inclined guide plate is fixedly connected to the inner side surface of the bottom shell. The collection tank is fixedly connected to the bottom end of the bottom shell. The discharge port is fixedly connected to the side surface of the collection tank. The elastic sliding rod penetrates from one side of the fixed rod cross plate to the other side. A spring is provided on the outside of the elastic sliding rod, and the two ends of the spring are respectively fixedly connected to the pressing filter plate and the fixed rod cross plate. The elastic sliding rods are symmetrically distributed about the vertical center line of the fixed rod cross plate. When the cleaning brush plate and the fixed plate bottom move up and down reciprocally together, the movement of the fixed plate bottom will drive the linkage rod connected to the bottom side to drive the connected fixed rod cross plate to move downward. At this time, the spring on the outside of the elastic sliding rod pushes the pressing filter plates on both sides to approach each other, and the side edges of the pressing filter plates are in mutual contact with the inclined surface of the inclined guide plate. As the linkage rod and the fixed rod cross plate move upward, the two pressing filter plates move away from each other along the elastic sliding rods, and the dust precipitates generated by the cleaning inside the bottom shell will move along the inclined guide plate and the pressing filter plates to the bottom surface of the bottom shell, playing a role in collecting the precipitates. At the same time, when the linkage rod and the fixed rod cross plate move downward, the fixed rod cross plate pushes the elastic sliding rod, causing the pressing filter plates that are in contact with the inclined guide plate to approach each other and move closer to the bottom of the bottom shell. During the movement of the pressing filter plates in contact with the inclined guide plate, the inclined guide plate is cleaned. In addition, the downward pressure of the inclined guide plate separates the dust from the liquid, concentrates the dust precipitates through extrusion, and collects them into the collection tank for convenient discharge through the discharge port for cleaning.

[0009] According to the above technical solution, a protection structure is provided at the top of the bottom shell. The protection structure includes a storage slide rail, a slide rail hinge block, a protection cover plate, and a flipping hinge bar. The storage slide rail is fixedly connected to the side surface of the bottom shell. The slide rail hinge block is slidably connected to the inside of the storage slide rail. The flipping hinge bar is hingedly connected to the side surface of the storage slide rail. The protection cover plate is fixedly connected to the top end of the flipping hinge bar. There are two storage slide rails on the side surface of the storage slide rail, and the two storage slide rails are symmetrically distributed about the vertical center line of the bottom shell. The flipping hinge bar is located inside the two slide rail hinge blocks. When starting the cleaning, it is necessary to manually pull the protection cover plate, and drive the flipping hinge bar to move through the movement of the protection cover plate. At this time, the flipping hinge bar drives the connected slide rail hinge block to slide along the inside of the storage slide rail through the rotating shaft, and then flip the protection cover plate to cover the top of the upper shell to prevent the liquid inside the upper shell from splashing, and press the top end of the air-conditioning filter by the protection cover plate. At the same time, after the protection cover plate is flipped through the flipping hinge bar and the slide rail hinge block, the slide rail hinge block slides downward along the storage slide rail, so that the protection cover plate is stored on the side surface of the upper shell.

[0010] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, by providing a horizontally arranged sliding rod, a sliding plate, a threaded rod, a rack, a coaxial gear, a rotating handle, a peristaltic tube, a connecting vibration rod, a knocking tooth block, a deflecting block, a nozzle, and a blocking tooth block, liquid is ejected from the end of the nozzle to wash the air conditioner filter screen inside the bottom shell, thereby washing the dust on the air conditioner filter screen clean. At the same time, the movement of the peristaltic tube drives the outer deflecting block to slide on the side of the connecting vibration rod, so that the spraying range of the nozzle is changed during the movement of the sliding plate, thereby improving the washing effect; In the present invention, by providing a short-axis connecting wheel, a short-axis hinge rod, a fixed connecting rod, a side brush fixing plate, a cleaning brush plate, a fixing plate bottom plate, and a rubber fixing strip, the fixed connecting rod drives the connected side brush fixing plate to move up and down, so that the cleaning brush plate inside the side brush fixing plate contacts both sides of the air conditioner filter screen, and the cleaning brush plate cleans the side of the air conditioner filter screen as the side brush fixing plate moves. At the same time, by inserting the air conditioner filter screen into the rubber fixing strips on both sides and using the resilience of the rubber material, the convex fixing strips in the rubber fixing strips clamp and fix the edge of the air conditioner filter screen, stretching the air conditioner filter screen from the arc shape, thereby improving the cleaning effect of the air conditioner filter screen; In the present invention, by providing a linkage rod, a fixed rod cross plate, a resilient sliding rod, a pressing filter plate, an inclined guide plate, a collection tank, and a discharge port, the dust sediment generated during the cleaning inside the bottom shell will move along the inclined guide plate and the pressing filter plate to the bottom surface of the bottom shell, playing a role in collecting the sediment. At the same time, during the movement of the pressing filter plate fitting on the inclined guide plate, it plays a role in cleaning the inclined guide plate. In addition, when the inclined guide plate is pressed down, the dust and liquid are separated, and the dust sediment is concentrated by extrusion and collected in the collection tank for convenient cleaning through the discharge port; In the present invention, by providing a storage slide rail, a slide rail hinge block, a protective cover plate, and a flipping hinge strip, the protective cover plate covers the top of the upper shell to prevent the liquid inside the upper shell from splashing, and presses the top end of the air conditioner filter screen. At the same time, after the protective cover plate is flipped through the flipping hinge strip and the slide rail hinge block, the slide rail hinge block slides downward along the storage slide rail, so that the protective cover plate is stored on the side of the upper shell.

[0014] Please refer to Figure 1-10, an embodiment of the present invention is a non-dead-angle automatic cleaning device for air conditioner screens, including a bottom shell 1. The top of the bottom shell 1 is fixedly connected to an upper shell 2. The inner top of the bottom shell 1 is fixedly connected to a support frame 3. The side of the upper shell 2 is fixedly connected to a driving motor 7. A flushing and cleaning assembly 4 is arranged inside the upper shell 2. The flushing and cleaning assembly 4 includes a horizontal slide bar 41, a sliding plate 42, a threaded rod 43, a gear bar 44, a coaxial gear 45, a rotating handle 46, a peristaltic tube 47, a connecting vibration rod 48, a knocking tooth block 49, a deflection block 410, a nozzle 411, and a retaining tooth block 412.

The coaxial gear 45 is rotatably connected to the surface of the support frame 3. The rotating handle 46 is fixedly connected to the upper surface of the coaxial gear 45. The peristaltic tube 47 is arranged outside the rotating handle 46. The connecting vibration rod 48 is fixedly connected to the inside of the upper shell 2. The knocking tooth block 49 is fixedly connected to the side surface of the connecting vibration rod 48. The deflection block 410 is rotatably connected to the outer side of the top end of the peristaltic tube 47. The nozzle 411 is fixedly connected to the inside of the deflection block 410. The retaining tooth block 412 is fixedly connected to the surface of the support frame 3. The peristaltic tube 47 is fixedly connected to the sliding plate 42. One end of the peristaltic tube 47 bypasses the outside of the rotating handle 46, and the part bypassing the peristaltic tube 47 is a rubber tube, and the peristaltic tube 47 at the top end part of the sliding plate 42 is a metal tube. When the driving motor 7 is in the working state, the rotation of the threaded rod 43 is driven by the operation of the driving motor 7 to drive the sliding plate 42 to slide along the horizontal slide bar 41. While the sliding plate 42 moves, it will drive the gear bar 44 connected to the bottom side to move along the retaining tooth block 412. The gear bar 44 blocked by the retaining tooth block 412 will deform and fit the retaining tooth block 412 to slide. Subsequently, the movement of the retaining tooth block 412 will mesh with the side surface of the coaxial gear 45 and drive the upper rotating handle 46 to rotate, so that the rotating handle 46 rotates to peristalsis the bottom part of the peristaltic tube 47, and the liquid inside the bottom shell 1 is vertically pumped into the deflection block 410 and the nozzle 411 connected to the top end of the peristaltic tube 47, so that the liquid sprays out from the end of the nozzle 411 to wash the air conditioner filter inside the bottom shell 1, thereby washing the dust on the air conditioner flat filter clean. The peristaltic tube 47 is rotatably connected to the deflection block 410, the nozzle 411 is communicated with the peristaltic tube 47, the deflection block 410 is slidably connected to the connecting vibration rod 48, the retaining tooth block 412 and the gear bar 44 are mutually attached, and the gear bar 44 is made of an elastic material. At the same time, during the movement of the sliding plate 42, it will contact the knocking tooth block 49 on the side surface of the connecting vibration rod 48 and cause a slight vibration of the liquid inside the upper shell 2 to assist in cleaning. In addition, the movement of the sliding plate 42 will drive the metal tube part of the top peristaltic tube 47 to move, and the movement of the peristaltic tube 47 drives the outer deflection block 410 to slide on the side surface of the connecting vibration rod 48, so that the spraying range of the nozzle 411 is changed during the movement of the sliding plate 42.Thereby improving the flushing effect.

[0015] A cleaning and positioning structure 5 is provided at the end of the threaded rod 43. The cleaning and positioning structure 5 includes a short-axis connecting wheel 51, a short-axis hinge rod 52, a fixed connecting rod 53, a cleaning brush plate 55, a fixed plate bottom plate 56, and a rubber fixing strip 57. The short-axis connecting wheel 51 is fixedly connected to the rear end of the threaded rod 43. The short-axis hinge rod 52 is rotatably connected to the inner side of the short-axis connecting wheel 51. The fixed connecting rod 53 is rotatably connected to the top of the short-axis hinge rod 52. The rubber fixing strips 57 are equidistantly distributed on the inner side of the upper housing 2. A convex fixing strip 58 is fixedly connected to the inner side of the rubber fixing strip 57. Side brush fixing plates 54 are provided on both sides of the rubber fixing strip 57. The cleaning brush plate 55 is fixedly connected to the inner side surface of the side brush fixing plate 54. When the threaded rod 43 rotates or reverses through the driving motor 7, it will drive the short-axis connecting wheel 51 connected to the threaded rod 43 to rotate. During the rotation of the short-axis connecting wheel 51, the short-axis hinge rod 52 is pushed by the eccentric short axis on the inner side to drive the fixed connecting rod 53 to move up and down reciprocally. Thus, the fixed connecting rod 53 drives the connected side brush fixing plate 54 to move up and down, so that the cleaning brush plate 55 on the inner side of the side brush fixing plate 54 contacts both sides of the air-conditioning filter, and as the side brush fixing plate 54 moves, the cleaning brush plate 55 cleans the side surface of the air-conditioning filter. The fixed plate bottom plate 56 is fixedly connected to the bottom end of the cleaning brush plate 55. The short-axis connecting wheel 51 is composed of two discs connected to an eccentric short axis. The short-axis hinge rod 52 is rotatably connected to the eccentric short axis. The rubber fixing strip 57 is fixedly connected to the inner wall of the upper housing 2. The rubber fixing strip 57 is slidably connected to the side brush fixing plate 54. At the same time, by inserting the air-conditioning filter into the rubber fixing strips 57 on both sides and using the resilience of the rubber material, the convex fixing strips 58 in the rubber fixing strips 57 clamp and fix the edge of the air-conditioning filter, stretching the air-conditioning filter from the arc shape for positioning, thereby improving the cleaning effect of the air-conditioning filter.

[0016] Working principle: When the drive motor 7 is in operation, the rotation of the drive motor 7 drives the threaded rod 43 to rotate, which in turn drives the sliding plate 42 to slide along the horizontally arranged slide bar 41. As the sliding plate 42 moves, it drives the gear rack 44 connected to the bottom side to move along the stop tooth block 412. The gear rack 44 blocked by the stop tooth block 412 will deform and slide along the stop tooth block 412. Subsequently, the movement of the stop tooth block 412 will engage with the side of the coaxial gear 45 and drive the upper rotating handle 46 to rotate. Thus, the rotation of the rotating handle 46 peristalsis the bottom part of the hose of the peristaltic tube 47, causing the liquid inside the bottom shell 1 to be pumped vertically into the peristaltic tube 47 and reach the deflection block 410 and the inner spray head 411 connected to the top of the peristaltic tube 47. As a result, the liquid sprays out from the end of the spray head 411 to wash the air-conditioning filter screen inside the bottom shell 1, thereby washing away the dust on the air-conditioning filter screen. At the same time, during the movement of the sliding plate 42, it contacts the knocking tooth block 49 on the side of the connecting vibrating rod 48, causing the liquid inside the upper shell 2 to vibrate slightly to assist in cleaning. In addition, the movement of the sliding plate 42 drives the metal tube part of the top peristaltic tube 47 to move. The movement of the peristaltic tube 47 drives the outer deflection block 410 to slide along the side of the connecting vibrating rod 48. Thus, during the movement of the sliding plate 42, the spraying range of the spray head 411 is changed, thereby improving the washing effect; When the threaded rod 43 rotates or reverses through the drive motor 7, it will drive the short-axis connecting wheel 51 connected to the threaded rod 43 to rotate. During the rotation of the short-axis connecting wheel 51, the eccentric short axis inside drives the short-axis hinge rod 52 to push the fixed connecting rod 53 to move up and down reciprocally. Thus, the fixed connecting rod 53 drives the connected side brush fixing plate 54 to move up and down, causing the cleaning brush plate 55 inside the side brush fixing plate 54 to contact both sides of the air-conditioning filter screen. Along with the movement of the side brush fixing plate 54, the cleaning brush plate 55 cleans the sides of the air-conditioning filter screen. At the same time, by inserting the air-conditioning filter screen into the rubber fixing strips 57 on both sides and utilizing the resilience of the rubber material, the protruding fixing strips 58 inside the rubber fixing strips 57 clamp and fix the edge of the air-conditioning filter screen, stretching the air-conditioning filter screen from its arc shape positioning, thereby improving the cleaning effect of the air-conditioning filter screen.

[0017] Please refer to Figure 1-10, on the basis of the above embodiments, in another embodiment of the present invention, a filtering structure 6 is provided inside the bottom shell 1. The filtering structure 6 includes a linkage rod 61, a fixed rod cross plate 62, an elastic sliding rod 63, a pressure - applying filter plate 64, an inclined guide plate 65, a collection groove 66, and a discharge port 67. The linkage rod 61 is fixedly connected to the bottom surface of the fixed plate bottom plate 56. The fixed rod cross plate 62 is fixedly connected to the bottom end of the linkage rod 61. The elastic sliding rod 63 is fixedly connected to the side surface of the fixed rod cross plate 62. The pressure - applying filter plate 64 is slidably connected to the outside of the elastic sliding rod 63. The inclined guide plate 65 is fixedly connected to the inner side surface of the bottom shell 1. The collection groove 66 is fixedly connected to the bottom end of the bottom shell 1. The discharge port 67 is fixedly connected to the side surface of the collection groove 66. When the cleaning brush plate 55 and the fixed plate bottom plate 56 move up and down reciprocally together, the movement of the fixed plate bottom plate 56 will drive the linkage rod 61 connected to the bottom side to drive the connected fixed rod cross plate 62 to move downward. At this time, the spring outside the elastic sliding rod 63 pushes the two pressure - applying filter plates 64 to approach each other. The side edges of the pressure - applying filter plates 64 are in contact with the inclined surface of the inclined guide plate 65. When the linkage rod 61 and the fixed rod cross plate 62 move upward, the two pressure - applying filter plates 64 move away from each other along the elastic sliding rod 63. The dust deposits generated by the cleaning inside the bottom shell 1 will move along the inclined guide plate 65 and the pressure - applying filter plates 64 to the bottom surface of the bottom shell 1, playing a role in collecting the deposits. The elastic sliding rod 63 penetrates from one side of the fixed rod cross plate 62 to the other side. A spring is provided on the outside of the elastic sliding rod 63, and the two ends of the spring are respectively fixedly connected to the pressure - applying filter plate 64 and the fixed rod cross plate 62. The elastic sliding rods 63 are symmetrically distributed about the vertical center line of the fixed rod cross plate 62. At the same time, when the linkage rod 61 and the fixed rod cross plate 62 move downward, the fixed rod cross plate 62 pushes the elastic sliding rod 63, making the pressure - applying filter plates 64 that are in contact with the inclined guide plate 65 approach each other and move closer to the bottom of the bottom shell 1. During the movement of the pressure - applying filter plate 64 in contact with the inclined guide plate 65, it plays a role in cleaning the inclined guide plate 65. In addition, the downward pressure of the inclined guide plate 65 separates the dust from the liquid, concentrates the dust deposits through extrusion, and collects them in the collection groove 66 for discharge through the discharge port 67 for convenient cleaning.

[0018] A protective structure 8 is provided at the top end of the bottom end housing 1. The protective structure 8 includes a storage slide rail 81, a slide rail hinge block 82, a protective cover plate 83, and a flipping hinge bar 84. The storage slide rail 81 is fixedly connected to the side surface of the bottom end housing 1. The slide rail hinge block 82 is slidably connected to the inner side of the storage slide rail 81. The flipping hinge bar 84 is hingedly connected to the side surface of the storage slide rail 81. The protective cover plate 83 is fixedly connected to the top end of the flipping hinge bar 84. There are two storage slide rails 81 provided on the side surface of the storage slide rail 81, and the two storage slide rails 81 are symmetrically distributed about the vertical center line of the bottom end housing 1. The flipping hinge bar 84 is located inside the two slide rail hinge blocks 82. When starting to clean, it is necessary to pull the protective cover plate 83 by hand, and drive the flipping hinge bar 84 to move through the movement of the protective cover plate 83. At this time, the flipping hinge bar 84 drives the connected slide rail hinge block 82 to slide along the inner side of the storage slide rail 81 through the rotating shaft, and then flip the protective cover plate 83 to cover the top of the upper end housing 2 to prevent the liquid inside the upper end housing 2 from splashing, and press the top end of the air conditioner filter by the protective cover plate 83. At the same time, after the protective cover plate 83 is flipped through the flipping hinge bar 84 and the slide rail hinge block 82, the slide rail hinge block 82 slides downward along the storage slide rail 81, so that the protective cover plate 83 is stored on the side surface of the upper end housing 2.

[0019] Working principle: When the cleaning brush plate 55 and the fixed plate bottom plate 56 move up and down reciprocally together, the movement of the fixed plate bottom plate 56 will drive the linkage rod 61 connected to the bottom side to drive the connected fixed rod cross plate 62 to move downward. At this time, the springs on the outer side of the elastic slide rod 63 push the two pressure filter plates 64 to approach each other, and the side edges of the pressure filter plates 64 are in mutual contact with the inclined surfaces of the inclined guide plates 65. As the linkage rod 61 and the fixed rod cross plate 62 move upward, the two pressure filter plates 64 move away from each other along the elastic slide rod 63, and the dust sediment generated by the cleaning inside the bottom end housing 1 will move along the inclined guide plates 65 and the pressure filter plates 64 to the bottommost surface of the bottom end housing 1, playing a role in collecting the sediment. At the same time, when the linkage rod 61 and the fixed rod cross plate 62 move downward, the fixed rod cross plate 62 pushes the elastic slide rod 63, so that the pressure filter plates 64 in contact with the inclined guide plates 65 approach each other and approach the bottom of the bottom end housing 1. During the movement of the pressure filter plates 64 in contact with the inclined guide plates 65, the inclined guide plates 65 are cleaned. In addition, the downward pressure of the inclined guide plates 65 will separate the dust from the liquid, concentrate the dust sediment through extrusion, and collect it in the collection tank 66 for convenient discharge through the discharge port 67 for cleaning.

[0020] When starting the cleaning, it is necessary to manually pull the protective cover plate 83, and the movement of the protective cover plate 83 drives the movement of the turning hinge bar 84. At this time, the turning hinge bar 84 drives the connected slide rail hinge block 82 to slide along the inner side of the storage slide rail 81 through the rotating shaft. Subsequently, the protective cover plate 83 is turned over so that the protective cover plate 83 covers the top of the upper housing 2 to prevent the liquid inside the upper housing 2 from splashing, and presses the top of the air conditioner filter through the protective cover plate 83. At the same time, after the protective cover plate 83 is turned over through the turning hinge bar 84 and the slide rail hinge block 82, the slide rail hinge block 82 slides downward along the storage slide rail 81, so that the protective cover plate 83 is stored on the side of the upper housing 2.
