Description

Technical Field

[0001] This utility model relates to the field of air purification and filtration technology, and in particular to an air purification and filtration absorber that is easy to maintain. Background Technology

[0002] Air purification filtration is a process used to purify air, typically applied in industrial, commercial, or large building environments. It removes pollutants such as particulate matter, harmful gases, and microorganisms from the air through multi-layer filtration technology. Its main components include the housing and multi-layer filtration system, etc.

[0003] Existing technologies, such as the utility model patent with publication number CN222027103U, disclose a duct-type air purifier that is easy to maintain. This utility model employs a duct-type air purifier that is easy to maintain, comprising a main housing with a hollow purification chamber inside. An air inlet and an air outlet are respectively installed on the left and right ends of the main housing, connected by the purification chamber. The side wall of the purification chamber has an openable / closable cabinet door, outside which the main control electrical components are installed. Several layers of guide rails are arranged inside the purification chamber, and several layers of lamp holders and photocatalyst meshes are spaced apart and installed on the guide rails. The openings of the guide rails face the cabinet door, and the lamp holders and photocatalyst meshes can be easily disassembled and installed from the cabinet door direction. By designing an openable / closable cabinet door on the side wall of the purification chamber, key purification components such as the internal guide rails, lamp holders, and photocatalyst meshes can be easily disassembled and installed from the cabinet door direction. This design greatly simplifies maintenance, allowing even non-professionals to quickly clean and replace parts, reducing maintenance costs and shortening maintenance time.

[0004] The following defects were found in response to the above: In air purification filtration, existing technologies often use multi-layer filtration systems for air purification. However, during long-term air purification, the filter screen is often contaminated by airborne particles and microorganisms. When the filter screen becomes contaminated and clogged, existing air purification filters usually can only remove the filter screen for maintenance and cleaning by disassembling the screws or the entire housing. This greatly reduces the efficiency of filter screen maintenance and may also damage the device or cause misinstallation during the disassembly process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing air purifier filters, which typically require disassembling screws or the entire housing to remove the filter for maintenance and cleaning when the filter is clogged. This significantly reduces the efficiency of filter maintenance and may also damage the device or cause misinstallation during the disassembly process. Therefore, this invention proposes an air purifier filter absorber that is easier to maintain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an easy-to-maintain air purifier filter absorber, comprising a housing, an inlet pipe, and an outlet pipe. The inner wall of the housing is provided with four mounting devices, each including two slide rails. The two slide rails are fixedly connected to the inner wall of the housing. The slide rails are U-shaped. Two rectangular strips are slidably connected to the inner walls of the two slide rails. A rectangular frame is fixedly connected to one end of the two rectangular strips that are close to each other. A rectangular plate is fixedly connected to one side of the rectangular frame. A storage frame is slidably connected to the inner wall of the rectangular frame. Two first screws are threaded to both sides of the rectangular frame. A limit plate is rotatably connected to the arc surface of each of the two first screws. Four indicator lights are fixedly connected to one side of the housing, and the four indicator lights are respectively located above the four mounting devices.

[0007] The above components achieve the following effects: the operator can directly pull the rectangular frame out of the box along the slide rail by pulling the rectangular plate, which facilitates quick disassembly of the filter screen for maintenance and cleaning, and facilitates quick installation of the filter screen or activated carbon. Rotating the two first screws can clamp and fix the two limiting plates in a direction that brings them closer to each other. The four indicator lights are different colors, and different filter materials are installed according to the different colors.

[0008] Preferably, a first handle is fixedly connected to one side of the rectangular plate, and the cross-section of the first handle is U-shaped.

[0009] The effect achieved by the above components is that the rectangular plate and rectangular frame can be pulled out of the box by using the first handle, which is more convenient and less strenuous.

[0010] Preferably, a plurality of anti-slip strips are fixedly connected to one side of each of the two limiting plates, and the plurality of anti-slip strips are evenly distributed on the limiting plates.

[0011] The effect achieved by the above components is that the anti-slip strip can increase the friction between the limiting plate and the storage frame, making the fixing effect of the limiting plate better.

[0012] Preferably, magnetic strips are fixedly connected to both sides of the rectangular frame, and the storage frame is made of iron.

[0013] The effect achieved by the above components is that the magnetic strips on both sides of the rectangular frame can attract the storage frame or the iron filter screen into the rectangular frame, preventing the storage frame or filter screen from detaching from the rectangular frame.

[0014] Preferably, the upper surface of the housing is provided with a cleaning device, the cleaning device including an outer frame, the outer frame being fixedly connected to the upper surface of the housing, the upper surface of the outer frame having two elliptical grooves, the inner walls of the two elliptical grooves being slidably connected to cylinders, the ends of the two cylinders away from the elliptical grooves being fixedly connected to a connecting plate, one side of the connecting plate being rotatably connected to a second screw, the end of the second screw away from the connecting plate being threadedly connected to a mounting plate, and the lower surface of the mounting plate being fixedly connected to a cleaning brush.

[0015] The effect achieved by the above components is as follows: when the filter screen needs to be cleaned, the filter screen can be placed directly into the outer frame, then water can be added, and then the second screw can be rotated to adjust the height of the cleaning brush so that it can contact the filter screen. Then, the connecting plate can be pulled back and forth in the oval groove to achieve the effect of cleaning the filter screen.

[0016] Preferably, a knob is fixedly connected to the end of the second screw away from the cleaning brush, and the upper surface of the knob has four arc grooves.

[0017] The effect achieved by the above components is that the second screw is rotated using a knob, making operation simpler and more convenient.

[0018] Preferably, a second handle is fixedly connected to the upper surface of the connecting plate, and the second handle is located in the center of the connecting plate.

[0019] The effect achieved by the above components is that by using the second handle to pull the connecting plate, the cylinder can slide in the elliptical groove, making the operation simpler and less strenuous.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by setting up an installation device, after long-term air purification and filtration, the filter screen will inevitably become dirty due to airborne particles. Therefore, it is necessary to disassemble and clean the filter screen regularly. By setting up an installation device, the filter screen can be quickly installed and removed, thereby increasing maintenance efficiency. The specific operation steps are as follows: When air purification is required, the corresponding filter material can be selected for installation according to the color of the indicator light. For example, activated carbon can be placed in the storage box, and the storage box can be adsorbed onto the magnetic strip, or the filter screen can be directly adsorbed onto the magnetic strip. However, before this, since there are two first screws threaded on both sides of the rectangular frame, and each of the two first screws is rotatably connected to a limiting plate, before installing the storage box or filter screen, the limiting plates located on both sides of the rectangular frame need to be rotated upwards along the arc surface of the first screws. This allows the filter screen or storage box to be placed in the rectangular frame. Then, the limiting plates are rotated downwards to correspond to the two sides of the filter screen or storage box to prevent the storage box from slipping off the rectangular frame. Finally, the filter screen or storage box is adsorbed onto the magnetic strips on both sides. Next, you need to manually push the first handle. Since the rectangular plate is fixedly connected to the handle, pushing the handle will also move the entire rectangular frame. It is important to note that when pushing, you need to align the rectangular strips on the top and bottom sides of the rectangular frame with the slide rail inside the box, and slide the rectangular frame into the box along the inner wall of the slide rail. This completes the installation. When you need to maintain and clean the filter or add activated carbon, you can directly pull the handle, then rotate the first screw to loosen the limiting plate, then rotate the limiting plate to the top, and then remove the filter or storage frame from the strip for maintenance or replenishment. The handle helps the operator save effort, and the anti-slip strips on the limiting plate increase the friction between the limiting plate and the filter or storage frame, making the fixing effect better.

[0022] In this invention, by setting up a cleaning device, after a long period of air purification and filtration, the filter screen will inevitably be polluted by particles or other substances in the air, causing its filtration effect to decrease significantly. Therefore, it is necessary to regularly maintain and clean the filter screen. The built-in cleaning device can directly clean the disassembled filter screen, greatly increasing the efficiency of maintenance. The specific operating steps are as follows: When it is necessary to clean the filter screen, firstly, the filter screen needs to be removed using the installation device, and then the filter screen is placed into the outer frame that is fixedly connected to the housing. Next, a small amount of water and cleaning agent can be placed in the outer frame. Before cleaning the filter screen, there are two oval grooves on the upper surface of the outer frame. Two cylinders are slidably connected to the inner walls of the oval grooves, and the cylinders are fixedly connected to the connecting plate. The connecting plate is rotatably connected to the second screw, which is threadedly connected to the mounting plate and the cleaning brush. Therefore, you can first turn the second screw by the knob to move the cleaning brush downward and make it contact the filter screen. At this time, you can pull the connecting plate by the second handle. The connecting plate drives the cleaning brush to move back and forth along the oval groove, thereby achieving the purpose of cleaning the filter screen. Turning the second screw by the knob makes the operation simpler, and pulling the connecting plate by the second handle saves more effort. Attached Figure Description

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: an easy-to-maintain air purification filter absorber, including a housing 1, an air inlet pipe 2, an air outlet pipe 3, four mounting devices 4 on the inner wall of the housing 1, and a cleaning device 5 on the upper surface of the housing 1.

[0030] The specific setup and function of the installation device 4 and the cleaning device 5 will be described in detail below.

[0031] Reference Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: each of the four installation devices 4 includes two slide rails 401, which are fixedly connected to the inner wall of the housing 1. The slide rails 401 are U-shaped. Two rectangular bars 402 are slidably connected to the inner walls of the two slide rails 401. The same rectangular frame 403 is fixedly connected to one end of the two rectangular bars 402 that are close to each other. A rectangular plate 404 is fixedly connected to one side of the rectangular frame 403. A storage frame 405 is slidably connected to the inner wall of the rectangular frame 403. Two first screws 406 are threadedly connected to both sides of the rectangular frame 403. The arc surfaces of the two first screws 406 are rotatably connected to limit plates 407. Four indicator lights 410 are fixedly connected to one side of the housing 1. The four indicator lights 410 are respectively located above the four installation devices 4. Operators can directly pull the rectangular plate 404 to pull the rectangular frame 403 out of the housing 1 along the slide rail 401, facilitating quick disassembly of the filter screen for maintenance and cleaning, as well as quick installation of the filter screen or activated carbon. Rotating the two first screws 406 clamps the two limiting plates 407 closer together. The four indicator lights 410 are different colors, indicating the installation of different filter materials. A first handle 411 is fixedly connected to one side of the rectangular plate 404. The cross-section of the first handle 411 is "U". Using the first handle 411, the rectangular plate 404 and the rectangular frame 403 can be pulled out of the housing 1, making it more convenient and effortless. Several anti-slip strips 408 are fixedly connected to one side of each of the two limiting plates 407, and the anti-slip strips 408 are evenly distributed on the limiting plates 407. The anti-slip strips 408 increase the friction between the limiting plates 407 and the storage frame 405, making the fixing effect of the limiting plates 407 better. Magnetic strips 409 are fixedly connected to both sides of the rectangular frame 403, and the storage frame 405 is made of iron. The magnetic strips 409 on both sides of the rectangular frame 403 can attract the storage frame 405 or the iron filter screen into the rectangular frame 403, preventing the storage frame 405 or the filter screen from detaching from the rectangular frame 403.

[0032] Reference Figure 5As shown in this embodiment, the cleaning device 5 includes an outer frame 51, which is fixedly connected to the upper surface of the housing 1. Two elliptical grooves 52 are formed on the upper surface of the outer frame 51. A cylinder 53 is slidably connected to the inner wall of each of the two elliptical grooves 52. A connecting plate 54 is fixedly connected to one end of each cylinder 53 away from the elliptical groove 52. A second screw 55 is rotatably connected to one side of the connecting plate 54. A mounting plate 57 is threadedly connected to one end of the second screw 55 away from the connecting plate 54. A cleaning brush 58 is fixedly connected to the lower surface of the mounting plate 57. When the filter needs cleaning, the filter can be directly placed into the outer frame 51, then water can be added. The second screw 55 is then rotated to adjust the height of the cleaning brush 58 so that it can contact the filter. Then, the connecting plate 54 is pulled back and forth in the elliptical groove 52 to achieve the effect of cleaning the filter. A knob 56 is fixedly connected to the end of the second screw 55 away from the cleaning brush 58. Four arc grooves are formed on the upper surface of the knob 56. The second screw 55 is rotated using knob 56, making operation simpler and more convenient. A second handle 59 is fixedly connected to the upper surface of the connecting plate 54, and the second handle 59 is located in the center of the connecting plate 54. By using the second handle 59 to pull the connecting plate 54, the cylinder 53 can slide in the elliptical groove 52, making operation simpler and less strenuous.

[0033] Working principle: In this utility model, by setting up the installation device 4, after long-term air purification and filtration, the filter screen will inevitably become dirty due to airborne particles. Therefore, it is necessary to disassemble and clean the filter screen regularly. By setting up the installation device 4, the filter screen can be quickly installed and removed, thereby increasing maintenance efficiency. The specific operation steps are as follows: When air purification is required, the corresponding filter material can be selected for installation according to the color on the indicator light 410. For example, activated carbon can be placed in the storage frame 405 and adsorbed onto the magnetic strip 409, or the filter screen can be directly adsorbed onto the magnetic strip 409. Prior to this, since there are two first screws 406 threadedly connected to both sides of the rectangular frame 403, and each of the two first screws 406 is rotatably connected to a limiting plate 407, before installing the storage frame 405 or the filter screen, the limiting plates 407 located on both sides of the rectangular frame 403 need to be rotated upwards along the arc surface of the first screws 406. This allows the filter screen or storage frame to be placed into the rectangular frame 403. Then, the limiting plates 407 are rotated downwards to correspond to the two sides of the filter screen or storage frame to prevent the storage frame from slipping off the rectangular frame 403. Finally, the filter screen or storage frame is attracted to the magnetic strips 409 on both sides. Next, the first handle 411 needs to be manually pushed. Since the rectangular plate 404 is fixedly connected to the handle, pushing the handle will also move the entire rectangular frame 403. It should be noted that when pushing, the rectangular strips 402 located on the upper and lower sides of the rectangular frame 403 need to be aligned with the slide rail 401 inside the housing 1, and the rectangular frame 403 should be slid into the housing 1 along the inner wall of the slide rail 401. This completes the installation operation. When the filter needs to be maintained and cleaned, or when activated carbon needs to be added, the handle can be pulled directly, and then the first screw 406 can be rotated to loosen the limiting plate 407. Then, the limiting plate 407 can be rotated to the top, and the filter or storage frame 405 can be removed from the strip for maintenance or replenishment. The handle helps the operator save effort, and the anti-slip strips 408 on the limiting plate 407 can increase the friction between the limiting plate 407 and the filter or storage frame 405, making the fixing effect better.

[0034] In this utility model, by setting up a cleaning device 5, after a long period of air purification and filtration, the filter screen will inevitably be polluted by particles or other substances in the air, causing its filtration effect to drop significantly. Therefore, it is necessary to regularly maintain and clean the filter screen. The built-in cleaning device 5 can directly clean the disassembled filter screen, greatly increasing the maintenance efficiency. The specific operation steps are as follows: When it is necessary to clean the filter screen, firstly, the filter screen needs to be removed through the installation device 4, and then the filter screen is placed into the outer frame 51 which is fixedly connected to the housing 1. Then, a small amount of water and cleaning agent can be placed in the outer frame 51. Before cleaning the filter screen, two elliptical grooves 52 are opened on the upper surface of the outer frame 51. Two cylinders 53 are slidably connected to the inner wall of the elliptical grooves 52. The cylinders 53 are fixedly connected to the connecting plate 54. The second screw 55 is rotatably connected to the connecting plate 54. The second screw 55 is threadedly connected to the mounting plate 57 and the cleaning brush 58. Therefore, the second screw 55 can be rotated by the knob 56 to make the cleaning brush 58 move downward and contact the filter screen. At this time, the connecting plate 54 can be pulled by the second handle 59. The connecting plate 54 drives the cleaning brush 58 to move back and forth along the elliptical grooves 52, thereby achieving the purpose of cleaning the filter screen. Rotating the second screw 55 by the knob 56 makes the operation simpler, and pulling the connecting plate 54 by the second handle 59 saves more effort.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection within a component, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection of two components.
