Description

Technical Field

[0001] This invention relates to the field of air conditioning technology for large spaces, and specifically to an intelligent industrial building HVAC system. Background Technology

[0002] High-ceiling space air conditioning systems are specialized air conditioning equipment developed for buildings with tall ceilings. They primarily address the heating, cooling, ventilation, and heat recovery needs of such spaces, offering a high level of comfort. With an air supply height of up to 30 meters, they are mainly used for temperature control in various factories, stadiums, exhibition halls, logistics warehouses, and other buildings with high ceilings. The heat source for high-ceiling space air conditioning systems can be chilled or hot water; traditional central air conditioning systems can all serve as their heat source, with the high-ceiling space air conditioner acting as a terminal device.

[0003] Existing high-ceiling air conditioners for industrial buildings (hereinafter referred to as air conditioners) have relatively simple structures and poor performance. Furthermore, many manufacturers have reported that the air conditioners installed in their production workshops are prone to clogging due to the simple structure of the inlet filters and the influence of particulate matter, smoke, dust, and other dust generated during raw material processing. This clogging obstructs airflow, significantly reducing the cooling or heating effect of the airflow after heat exchange; the jet airflow at the outlet is further weakened, severely limiting the cooling or heating effect in the workshop and resulting in resource waste.

[0004] Furthermore, the air conditioner is installed at a relatively high height, requiring workers to use special auxiliary lifting equipment to approach it for cleaning, which is very inconvenient and poses significant safety hazards due to working at height. Moreover, the air inlet filter is built-in, requiring the air conditioner casing to be opened to remove it for cleaning or replacement, which is time-consuming and labor-intensive.

[0005] Furthermore, existing air conditioners suffer from poor heat exchange efficiency. The airflow entering the casing from the inlet quickly passes through the heat exchange coils and exits through the exhaust vent. In summary, the heat exchange path between the airflow and the heat source in the heat exchange coils is relatively short. Consequently, under preset temperature cooling or heating control, the heat exchange effect resulting from this rapid airflow is minimal. Therefore, to achieve a suitable temperature in the workshop, traditional air conditioners must either lower the preset temperature control (cooling) or raise the preset temperature control (heating), leading to poor heat exchange efficiency and energy waste. Summary of the Invention

[0006] In order to address the shortcomings and deficiencies of existing air conditioners, this invention provides an intelligent high-ceiling air conditioner with an externally mounted filter structure that is easy to connect and install, intelligent and automated lifting operation, time and labor saving, energy saving and improved heat exchange effect.

The first motor is mounted on the hoisting plate via a bracket, and its output shaft is connected to the lead screw to maintain synchronous rotation.

[0013] As a preferred technical solution, the hoisting structure includes a hoisting plate, a pulley, a wire rope, a winding reel, and a winding motor; the hoisting plate is movably mounted on the mounting plate and has an internal cavity, with a hook on the top surface of the filter box; the winding motor is located in the cavity, and its output shaft is connected to the winding reel; the pulley is located in the cavity, and one end of the wire rope is connected to the winding reel, while the other end passes around the pulley, extends downward, and connects to the hook.

[0014] In a further preferred technical solution, the pulley, hook, wire rope, and winding reel are three sets of matched installations, and the three hooks are distributed in an equilateral triangle; a positioning plate is also provided between the three wire ropes to ensure that the wire ropes can be raised and lowered stably.

[0015] In a further preferred embodiment, the hoisting structure further includes a vertical plate, a rotating screw, a second motor, a rotating block, and a guide rod; the vertical plate is disposed at one end of the mounting plate; the rotating block is disposed on the hoisting plate; the rotating screw passes through the vertical plate and maintains a rotatable connection with the rotating block, and the output shaft of the second motor is connected to the rotating screw; the guide rod is T-shaped and slidably disposed on the mounting plate so that the rotating screw rotates, driving the rotating block and the hoisting plate to move left and right as a whole.

[0016] In a further preferred embodiment, the hoisting structure further includes connecting rods, connecting sleeves, locking rods, and electric push rods; there are multiple connecting rods, evenly distributed in the filter box, with locking holes on one side of each connecting rod; there are multiple connecting sleeves matching the connecting rods, located on one side of the box; the connecting sleeves have cross-shaped through slots; the electric push rods are located in the box, with their output ends connected to the locking rods, so that when the filter box is installed with the box, the connecting rods pass through the through slots in the left-right direction, and the locking rods pass through the locking holes and the through slots in the front-back direction.

The scissor arm combination structure is simple, providing more stable and reliable lifting and lowering of the filter box, laying the foundation for subsequent precise positioning and installation. Furthermore, it utilizes a hoisting structure combining steel wire ropes and pulleys, suitable for air conditioners connected to building ceilings and installed at higher heights. The steel wire rope structure allows for high-altitude lifting operations within limited space, offering a simple structure and higher cost-effectiveness, and providing the foundation for subsequent precise positioning and installation of the filter box driven by the steel wire rope. This achieves intelligent and automated filter box lifting operations, avoiding the hassle and safety hazards of high-altitude cleaning and replacement, saving time and effort. Additionally, it employs a rotating screw and a second motor for left-right displacement, and a locking structure securely installs the filter box, with sealing gaskets at the connection points maintaining a tight seal.

[0021] The adoption of finned heat exchange coils further increases the area of ​​airflow contact with the heat source for heat exchange, thereby improving the heat exchange effect. Simultaneously, two cooperating guide vanes with specially distributed guide fins are used, causing the airflow entering the inner center of the finned heat exchange coil to form a zigzag downward airflow direction under the action of the guide vanes, flowing through the heat exchange coil multiple times. This further increases the travel distance of the airflow through the finned heat exchange coil, enhancing the heat exchange effect and avoiding the problem of airflow entering from the inlet and quickly passing through the heat exchange coil and exiting from the exhaust port. This achieves the goal of improving heat exchange effect while saving energy, making it more practical and easier to promote to the market. Attached Figure Description

Without further limitations, the use of phrases such as "comprising a..." to define an element does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, 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; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Example 1: As Figures 1-11 As shown:

[0041] An intelligent industrial building HVAC system includes a mounting plate 1, a housing 2, a filter element mechanism 3, and a heat exchange mechanism 4. Among them, for example... Figure 1 As shown: Mounting plates 1 are distributed on the left and right sides and are fixed to the top surface by fastening bolts. The top surface can be the interior ceiling of a tall building or a supporting steel beam inside the building. Mounting plates 1 are connected and fixed to the housing 2 by multiple evenly distributed screws 11 to ensure the installation balance of the housing. Spring vibration dampers 12 are also provided between the screws 11 and the housing 2 to reduce vibration or shaking and to provide a buffering effect.

[0042] like Figure 3 As shown: the housing 2 has a hollow structure, and air inlets 21 are located on the upper left and right sides of the housing 2. The housing 2 is made of double-layer steel plates with a sandwich layer of high-pressure injected polyurethane (PU) foam insulation material. The filter element mechanism 3 is mounted on the air inlet 21 via a hoisting structure 23, allowing for easy removal and replacement. After being raised to a preset position, the filter element mechanism 3 is precisely positioned and secured with the air inlet 21. This design utilizes an external filter structure, facilitating easy connection, installation, disassembly, cleaning, and replacement. It also enhances the heat exchange effect of the air conditioner to a certain extent, saving energy and extending its service life.

[0043] In this embodiment, as Figure 3 As shown: The hoisting structure 23 includes a hoisting plate 51, a movable rod 52, a fixed rod 53, a shear arm 54, and a support plate 55. The hoisting plate 51 is arranged parallel to and movably mounted on the mounting plate 1. The purpose of moving the hoisting plate is to allow it to be moved a preset distance before the filter box is completely disassembled for replacement or cleaning, so that the filter box can be unlocked and separated from the air inlet of the box body, thereby ensuring free and stable vertical movement. The movable rod 52 is movably mounted on one side of the hoisting plate 51, and the fixed rod 53 is distributed front to back on the right side of the hoisting plate 51.

[0044] Among them, such as Figure 3As shown: there are multiple shear arms 54, with two intersecting shear arms 54 forming one section; two symmetrically distributed shear arm sections 54 form a group, hinged together by connecting rods distributed front and back. The shear arm 54 structure consists of multiple groups distributed vertically; the shear arms 54 are hinged to the moving rod 52 and the fixed rod 53. The intersection of two shear arms 54 and between adjacent vertical shear arms 54 are hinged together by connecting rods 56, allowing the moving rod 52 to move, enabling the shear arm structure to extend or retract, and allowing the support plate 55 to perform lifting operations. The structure at the support plate 55 is the same as that at the lifting plate 51, and the support plate 55 is connected to the filter box 31 by fastening bolts. The purpose of this arrangement is to form a shear lifting structure by combining multiple shear arms of preset lengths, specifically as follows... Figure 7 As shown.

[0045] like Figure 4 As shown: In this embodiment, the hoisting structure 23 further includes a driving component 57, which includes a first motor 571, a lead screw 572, and a driving block 573. The driving block 573 is located in the middle of the moving rod 52, has a square structure, and the two are integrally formed. The lead screw 572 is distributed on both sides, with one end passing through the side wall of the hoisting plate 51 and the other end maintaining a threaded rotational connection with the driving block 573. The first motor 571 is mounted on the hoisting plate 51 via a bracket, and its output shaft is connected to the lead screw 572 to maintain synchronous rotation.

[0046] The scissor arm assembly hoisting structure is suitable for air conditioners with steel structure connections and supports, and installed at a relatively low height. Furthermore, the scissor arm assembly structure is simple to install and provides more stable and reliable lifting and lowering of the filter box, laying the foundation for subsequent precise positioning and installation. The rotation of the first motor drives the lead screw to rotate synchronously, which in turn moves the drive block and the moving rod as a whole, causing the scissor arm structure to lengthen and thus lower the filter box. This air conditioner achieves intelligent and automated filter box lifting and lowering operations, avoiding the trouble and safety hazards of high-altitude cleaning and replacement. Whether cleaning or replacing the filter element, it is time-saving, labor-saving, and more efficient.

[0047] In this embodiment, as Figure 6 As shown, the hoisting structure 23 also includes a vertical plate 71, a rotating screw 72, a second motor 73, a rotating block 74, and a guide rod 75. The vertical plate 71 is located at one end of the mounting plate 1; the rotating block 74 is located on the hoisting plate 51. One end of the rotating screw 72 passes through the vertical plate 71 and is rotatably connected to the rotating block 74, and the output shaft of the second motor 73 is connected to the rotating screw 72. This allows the rotating screw 72 to rotate, driving the rotating block 74 and the hoisting plate 51 to move left and right as a whole, facilitating the movement, disassembly, and installation of the filter box, and providing a foundation for subsequent lifting operations.

[0048] like Figure 6As shown: Guide rod 75 is T-shaped and slidably mounted on mounting plate 1. This design provides guidance and support for the lifting plate. The filter box mainly supports the filter element and other structures, and is relatively lightweight. A limiting rod is also provided on the side wall of the box to limit the position of the filter box. Initially, the filter box is in contact with the end of the limiting rod. After the filter box descends to complete the cleaning or replacement of the filter element, it rises again to the preset height, where the limiting rod acts as a limit. In this state, the air inlet of the box and the air outlet of the filter box are coaxially aligned, and the outer diameter of the air outlet is equal to the inner diameter of the air inlet. A rubber sealing ring is also provided at the connection between the air outlet and the air inlet to ensure a tight seal.

[0049] In this embodiment, as Figure 5 As shown: The hoisting structure 23 also includes a connecting rod 81, a connecting sleeve 82, a locking rod 83, and an electric push rod 84. See details... Figure 8 The image shows a three-dimensional view. Multiple connecting rods 81 are evenly distributed within the filter box 31, with locking holes 85 on one side of each rod. Multiple connecting sleeves 82 are matched to the connecting rods 81 and are located on one side of the housing 2. Each connecting sleeve 82 has a cross-shaped through groove 86. An electric push rod 84 is located on the housing 2, with its output end connected to a locking rod 83. This allows the connecting rods 81 to pass through the left-right through grooves 86 when the filter box 31 is installed with the housing 2, and the locking rod 83 to pass through the locking holes 85 and the through grooves 86 in the front-back direction. The electric push rod 84 is an electro-hydraulic push rod, which provides greater stability and smoother output.

[0050] The filter box adopts a square structure. Therefore, it is preferable that the connecting rod 81, connecting sleeve 82, locking rod 83, and electric push rod 84 are arranged in a ring, evenly distributed and matched four sets. This arrangement ensures sufficient and balanced tightening force, thereby guaranteeing the stability of the connection between the filter box and the housing. Furthermore, since a rubber sealing ring is provided at the connection between the air inlet and the air outlet, the movement of the lifting plate ensures the positioning and guiding installation of the air inlet and the air outlet. Therefore, an inclined surface is provided to match the locking rod and the locking hole. The pushing and inserting of the locking rod will cause the connecting rod with the locking hole to continue moving, that is, the air outlet continues to move towards the air inlet. This process will compress the rubber sealing ring, further achieving a sealing effect and preventing air leakage.

[0051] In this embodiment, as Figure 3 As shown: The filter element mechanism 3 includes a filter box 31, a filter element 32, and a pressing element 33. The filter box 31 has a quadrangular prism structure and is hollow inside. The inner diameter of this hollow area is equal to the outer diameter of the filter element. The outer surface of the filter box 31 has multiple evenly distributed air inlets 34, and the right side has an air outlet 35. This "outer surface" can be any one or a combination of the front side, rear side, and bottom side of the filter box.

[0052] like Figure 9As shown: the filter element 32 is cylindrical and includes a first filter screen 321, a filter plate 322, and an activated carbon screen 323 distributed sequentially from the outside to the inside. Figure 10 As shown: Filter plate 322 is made of PET material and forms a columnar structure through a folded structure. Filter plate 322 has many small ventilation holes; activated carbon mesh 323 is composed of activated carbon impregnation material. The purpose of this design is not only to serve as the core support for the overall filter element structure, but also to increase the contact area for air intake filtration, making it easier to achieve a good purification and filtration effect. All three components are closed at one end by a solid cover plate 324 and connected to a base plate 325 at the other end. The base plate 325 has a through hole 326 in the center and a concave cross-section. The cover plate ensures no ventilation and facilitates pressing and tightening. The "concave" base plate design is designed to complement the filter box structure, facilitating the positioning and installation of the filter element, and further ensuring that the air entering from the air inlet is filtered and purified by the filter element before being discharged unidirectionally from the through hole to the air outlet.

[0053] like Figure 11 As shown: In this embodiment, the pressing member 33 is used to press and tighten the filter element 32 with a preset clamping force after the filter element 32 is installed. Preferably, the pressing member 33 includes a pressing plate 331, a compression spring 332, and a pressing plate 333. The pressing plate 331 is hinged to the filter box 31 and can be opened and closed. A sealing ring is also provided at the connection between the pressing plate and the filter box. The pressing plate 331 has a groove 334, the compression spring 332 is disposed in the groove 334, and the pressing plate 333 is disposed in the groove 334 and located outside the compression spring 332, so that the pressing plate 333 can move. The purpose of this arrangement is to ensure the tight positioning of the filter element and prevent it from shaking.

[0054] In this embodiment, as Figure 3 As shown: The heat exchange mechanism 4 includes a finned heat exchange coil 41, a condenser plate 42, an axial fan 43, and a flow guide and silencer 44. The finned heat exchange coil 41 is mounted inside the housing 2 via a bracket and is located at the output end of the air inlet 21. The input end of the heat exchange coil is connected to an external heat source, and the output end is connected to the outside via a drain pipe. The finned heat exchange coil is a square spiral coil, meaning its shape appears square when viewed from above. The condenser plate 42 is located below the finned heat exchange coil 41, and the axial fan 43 is located at its center. The flow guide and silencer 44 is located below the axial fan 43. A swirl air outlet 22 is located at the bottom of the housing 2, and the swirl air outlet 22, the flow guide and silencer 44, and the axial fan 43 are aligned along their central axes. The air conditioner is powered by an external power source via an electrical plug.

[0055] Among them, such as Figure 3As shown: A guide plate 45 is also provided inside the housing 2. Multiple guide vanes 46 are evenly distributed on the guide plate 45, all of which are angled downwards. The guide plate 45 includes a first guide plate 451, a second guide plate 452, and a third guide plate 453. The first and second guide plates 451 and 452 are respectively located below the left and right air inlets 21 and are connected to the side walls by fastening bolts. The third guide plate 453 is vertically installed in the housing 2 and located at the center of the finned heat exchange coil 41. Guide vanes 46 are provided on both sides of the third guide plate 453. The top of the third guide plate is fixedly connected to the top wall of the housing. In this embodiment, there are three guide vanes on both the first and second guide plates 451 and 452, and they are evenly distributed. The third guide plate 453 also has three guide vanes on both sides, which are staggered from the guide vanes of the first and second guide plates, thus forming a downward zigzag airflow direction.

[0056] The use of finned heat exchange coils 41 increases the area of ​​airflow contact with the heat source for heat exchange, thereby improving the heat exchange effect. Simultaneously, two cooperating guide plates 45 and specially distributed guide vanes 46 are employed, which, under the action of the guide vanes 46, facilitate the formation of a zigzag downward airflow direction when airflow enters the inner center of the finned heat exchange coil 41. This allows the airflow to pass through the heat exchange coil multiple times, further increasing the travel distance of the airflow through the finned heat exchange coil 41, enhancing the heat exchange effect, and preventing the problem of airflow entering from the inlet end and quickly passing through the heat exchange coil before being discharged from the exhaust port. This achieves the goal of improving heat exchange effect while saving energy.

[0057] The working principle of an intelligent industrial building HVAC system:

[0058] First, the staff assembled all the components of the air conditioner. Then, using auxiliary lifting equipment, they secured the mounting plate 1 to the ceiling of the factory workshop using expansion bolts. Next, the air conditioner was hoisted as a whole using auxiliary hoisting equipment, and screws 11 and spring vibration dampers 12 were installed to ensure the stable installation of the air conditioner casing 2. Finally, the external cold and heat sources were connected via water pipes, and the system was drained to the outside through a drain pipe. After debugging, it was ready for normal operation.

[0059] During normal operation of the air conditioner, the use of finned heat exchange coils 41 increases the area of ​​airflow contact with the heat source for heat exchange, thereby improving the heat exchange effect to a certain extent. Simultaneously, two cooperating guide plates 45 (forming a group) and specially distributed guide vanes 46 are used, causing the airflow entering the inner center of the finned heat exchange coil 41 to form a zigzag downward airflow direction under the action of the guide vanes 46, flowing through the heat exchange coil multiple times. This further increases the travel distance of the airflow through the finned heat exchange coil 41, achieving the goal of improving heat exchange effect while saving energy.

[0060] In the initial state, the connecting rod 81 passes through the through groove 86 in the left-right direction, and the locking rod 83 passes through the locking hole 85 and the through groove 86 in the front-back direction, maintaining a stable connection between the filter box 31 and the box body 2. The shear arm 54 structure is in a folded and retracted state. In this state, the distance between the moving rod 52 and the fixed rod 53 is at its maximum.

[0061] When the air conditioner needs to have its filter structure (filter element 32) replaced or cleaned after a period of operation, the workshop manager activates the electro-hydraulic push rod via a control switch. The electro-hydraulic push rod retracts the locking rod 83, completing the unlocking operation. At this time, the connecting rod 81 can be easily moved out of the through groove 86. The movement of the filter boxes 31 on both sides is the same as that of the hoisting structure 23. Here, we take the movement of the left filter box 31 as an example.

[0062] The workshop manager starts the second motor 73 via a control switch. The second motor 73 is a servo motor. Therefore, the clockwise rotation of the second motor 73 will drive the rotating screw 72 to rotate synchronously, thereby causing the rotating block 74 to move to the left along the rotating screw 72. At this time, the lifting plate 51 and the entire structure connected to the lifting plate 51 will move to the left. Specifically, the filter box 31 will move to the left by a preset distance (which can be controlled by rotating the servo motor a preset number of times) and disengage from the box body 2, ensuring that the downward movement of the filter box 31 will not interfere.

[0063] The next step is to activate the first motor 571, which is also a servo motor. The first motor 571 rotates clockwise, causing the drive block 573 to move to the right, simultaneously moving the moving rod 52 along the slide rail on the hoisting plate 51. This, in turn, causes the multiple shear arm 54 structures to open, lengthening the overall structure. That is, the angle between two shear arms 54 within the same section, initially acute, gradually increases to an obtuse angle. This hoisting and lifting structure using shear arm 54 combinations is suitable for air conditioners with steel structure connections and supports, and installed at relatively low heights. Generally, air conditioners installed with steel beam connections are relatively low in height. This air conditioner allows for intelligent and automated lifting of the filter box 31, avoiding the hassle and safety hazards of high-altitude cleaning and replacement. Whether cleaning or replacing the filter element 32, it is time-saving and labor-saving.

[0064] After the management personnel clean or replace the filter element 32, the first motor 571 is started and rotated counterclockwise. This causes the drive block 573 to move to the left, and simultaneously causes the moving rod 52 to move to the left along the slide groove set on the lifting plate 51. This, in turn, causes the multiple sets of shear arms 54 to retract as a whole, shortening the overall structure of the shear arms 54, thereby causing the filter box 31 to move upward. Then, under the action of the limit rod, the filter box 31 is blocked, and the first motor 571 stops operating. At this time, the air outlet 35 and the air inlet 21 of the filter box 31 are coaxial, but there is a gap between them.

[0065] Next, the control switch starts the second motor 73. The second motor 73 rotates counterclockwise, causing the rotating block 74 to move to the right and reset along the rotating screw 72. At this time, the hoisting plate 51 and the filter box 31 will move to the right, and the air outlet 35 and the air inlet 21 will gradually approach and reset. During this reset process, the right air outlet 35 of the filter box 31 first enters the air inlet 21 of the box 2, thus completing the precise positioning and installation between the filter box 31 and the box 2. The connecting rod 81 of the filter box 31 will be inserted into the through groove 86. Then the electric hydraulic push rod is activated to start the reset operation. Specifically, the electric hydraulic push rod extends, which will drive the locking rod 83 to extend and insert into the position where the through groove 86 communicates with the locking hole 85, thus completing the locking operation between the filter box 31 and the box 2, further enhancing the stability of the connection between the two.

[0066] Example 2: This example is largely similar to the technical solution of Example 1, except that: Figure 12 As shown: The hoisting structure 23 includes a hoisting plate 51, pulleys 61, wire rope 62, winding reel 63, and winding motor 66. The hoisting plate 51 is movably mounted on the mounting plate 1 and has an internal cavity. The top surface of the filter box 31 has hooks 64. The winding motor 66 is located in the cavity, and its output shaft is connected to the winding reel 63. Figure 12As shown, this embodiment takes the distribution structure of the left filter box and the hoisting plate as an example; the winding disc 63 and the winding motor 66 are located on the right side of the cavity of the hoisting plate 51.

[0067] A pulley 61 is disposed within the cavity. One end of a wire rope 62 is connected to a winding reel 63, and the other end passes over the pulley 61, extends downward, and connects to a hook 64. Preferably, the pulley 61, hook 64, wire rope 62, and winding reel 63 are three sets of matched components, and the three hooks 64 are arranged in an equilateral triangle. Figure 13 As shown. A positioning plate 65 is also provided between the three wire ropes 62 to ensure stable lifting and lowering of the wire ropes 62. The positioning plate maintains frictional contact with all three wire ropes. A protrusion is provided in the middle of the wire rope, which is smoothly connected to the wire rope to form a slightly protruding part in the middle of the wire rope, so that the positioning plate is optimally positioned in the middle of the wire rope.

[0068] A hoisting structure using steel wire rope 62 and pulley 61 is further adopted, suitable for air conditioners connected to the interior ceiling and installed at a relatively high height. The steel wire rope structure allows for high-altitude lifting operations within limited space, offering a simple structure and higher cost-effectiveness. This provides a foundation for the subsequent precise positioning and installation of the filter box 31 by the steel wire rope 62. This enables intelligent and automated filter box lifting operations, avoiding the hassle and safety hazards of high-altitude cleaning and replacement. The winding motor 66 drives three spaced winding discs 63 to rotate synchronously, thereby driving the three steel wire ropes 62 to move up or down synchronously, ensuring lifting stability. Simultaneously, a positioning plate 65 is used to assist in preventing steel wire rope swaying due to excessive height, further ensuring the smoothness of filter box lifting.
