Description

Technical Field

[0001] The invention belongs to the technical field of HVAC, and in particular is a modular HVAC filter device that can be quickly disassembled, assembled and maintained. Background Art

[0002] HVAC is an important equipment that integrates heating, ventilation and air conditioning functions. Its name comes from the comprehensive abbreviation of the three core functions of heating, ventilation and air conditioning. It is mainly composed of supply fans, exhaust fans and air ducts. The supply fans are responsible for introducing fresh air from outdoors or treated clean air to maintain indoor air renewal and sufficient oxygen; the exhaust fans discharge indoor dirty air, moisture and odor in time. The air duct serves as an air delivery channel to ensure smooth air circulation. To ensure the quality of the air delivered to the room, a filter module is installed inside the air inlet fan to filter the incoming air, effectively intercept dust and other pollutants to prevent them from entering the room, thereby creating a comfortable and healthy indoor environment for people.

[0003] In modern buildings and industrial environments, modular HVAC filtration devices are widely used due to their convenient maintainability and flexible combination. However, in actual operation, the device exposes obvious limitations. When in high-load usage scenarios, the multi-layer stacked filter plates inside can achieve efficient filtration, but also produce negative effects. As the operating time increases, the pollutants intercepted by the filter plates continue to accumulate, further hindering air circulation and causing ventilation efficiency to be significantly reduced. The decrease in ventilation efficiency not only requires the HVAC to consume more energy to maintain the established air handling volume, but also leads to an increase in the equipment operating load, which directly affects the overall operating efficiency of the modular HVAC, increases operating costs and reduces the service life of the equipment. Summary of the invention

[0004] The object of the present invention is to provide a modular HVAC filter device that can be quickly disassembled and maintained, so as to solve the problems raised in the above-mentioned background technology.

A ventilation duct is fixedly installed on the left side of the HVAC air supply housing. A quick-disassembly filter assembly is fixedly installed on the inner wall of the HVAC air supply housing and is located at the connection between the ventilation duct and the HVAC air supply housing. The quick-disassembly filter assembly includes a second filter plate frame fixedly installed on the inner wall of the HVAC air supply housing. A worm is rotatably installed on the bottom side inside the HVAC air supply housing. A motor bracket is fixedly installed on the top of the HVAC air supply housing. A motor is fixedly installed inside the motor bracket, and the output shaft of the motor extends to the inside of the HVAC air supply housing and is fixedly connected to one end of the worm. A rotating shaft is rotatably installed on the inner wall of the HVAC air supply housing. A turbine is fixedly installed at the end of the rotating shaft, and the worm meshes with the turbine. A rotating center block is fixedly installed on the outer surface of the turbine. A first filter plate frame is fixedly installed on the side of the rotating center block. Placement grooves are formed inside the second filter plate frame and the first filter plate frame. A first filter plate and a second filter plate are respectively slidably installed inside the placement grooves. A quick-disassembly filter assembly is fixedly installed on the front of the first filter plate frame and the second filter plate frame. An inductor is fixedly installed on the inner top of the HVAC air supply housing. A connection pipe is fixedly installed on the right side of the HVAC air supply housing and is interconnected.

[0006] Preferably, the quick-disassembly filter assembly includes a first L-shaped bracket fixedly installed on the front of the first filter plate frame and the second filter plate frame. A second L-shaped bracket is fixedly installed at the distal end of the first L-shaped bracket on the front of the first filter plate frame and the second filter plate frame, and a fixing groove is provided inside the second L-shaped bracket. A roller is rotatably installed inside the first L-shaped bracket. A limiting plate is fixedly sleeved on the outer surface of the roller. A magnetic attraction convex block is fixedly installed at the bottom side of the other end of the limiting plate, and the magnetic attraction convex block is exactly magnetically attracted to the fixing groove provided inside the second L-shaped bracket. An auxiliary assembly is fixedly connected to one side of the placement groove.

[0007] Preferably, the auxiliary assembly includes a spring fixedly connected to one side of the placement groove. The other end of the spring is fixedly connected to a connecting plate, and the other side surface of the connecting plate abuts against the first filter plate, and the diameter of the connecting plate is smaller than the diameter of the placement groove.

[0008] Preferably, a protective door is interactively installed on the front of the HVAC air supply housing. The protective door and the HVAC air supply housing are hinged by a hinge. A handle is fixedly installed on the front of the protective door.

[0009] Preferably, a flow guide cover is fixedly installed on the inner wall of the HVAC air supply housing, and the flow guide cover is located at the connection between the ventilation duct and the HVAC air supply housing and is in a shape that is wider on the left and narrower on the right.

[0010] Preferably, a protective grille is fixedly mounted on the end of the air inlet duct, and the diameter of the protective grille is equal to the diameter of the air inlet duct.

[0011] Preferably, the rotating center block is fixedly mounted at the center of the turbine, and the upper end outer surface of the first filter plate frame is fixedly mounted to the side surface of the rotating center block.

[0012] Preferably, the handle is C-shaped and is located in the middle of the outer surface of the protective door.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. When the system monitors that the sensor detects high-load operation, which leads to accumulation of pollutants on the first filter plate and the second filter plate and reduced ventilation efficiency, the present invention intelligently starts the motor to drive the transmission component turbine, worm, rotating center block and the first filter plate frame, and cleverly realizes precise transmission through gear meshing. By rotating the first filter plate to be perpendicular to the second filter plate, the single filter screen filtering mode is switched to effectively expand the ventilation area, quickly increase the ventilation volume, and ensure that the connecting pipe supplies air to the room stably and efficiently. This design can not only maintain the established air handling capacity of the HVAC, but also reduce the equipment operating load, reduce energy consumption and mechanical wear, and extend the service life of the equipment. At the same time, the sensor promptly issues an alarm to remind the replacement of the filter screen, so as to avoid secondary pollution or equipment failure caused by excessively dirty filters, ensure indoor air quality, and realize intelligent, efficient and energy-saving ventilation management.

[0015] 2. The present invention uses a magnetic limiting structure of a limiting plate and a magnetic protrusion. The staff only needs to apply external force to flip the limiting plate to quickly release the fixing restriction on the first filter plate and the second filter plate. With the elastic recovery effect of the auxiliary component, the components can slide out automatically, and disassembly can be completed without complicated tools, which significantly improves maintenance efficiency. At the same time, during normal use, the limiting plate can reliably limit and fix the first filter plate and the second filter plate to ensure stable operation of the components and prevent loosening and displacement. This design takes into account both the operating stability and maintenance convenience of the equipment, effectively reduces the difficulty and time cost of maintenance, and provides a guarantee for the continuous and efficient operation of the equipment.

[0016] 3. The present invention greatly improves the maintenance efficiency through ingenious structural linkage. When the limit plate releases the limit on the first filter plate and the second filter plate, the spring drives the connecting plate to move outward by virtue of its elastic recovery characteristics. The abutment relationship between the connecting plate and the first filter plate and the second filter plate is utilized to push the two to slide outward along the placement groove, so that parts replacement does not require laborious disassembly or precise operation, thereby reducing the difficulty of maintenance. This automated auxiliary removal mechanism reduces the intensity of manual operation and avoids damage to parts caused by repeated disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Such as Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a modular HVAC filter device that can be quickly disassembled and maintained, including an HVAC air supply housing 1. An air inlet pipe 4 is fixedly installed on the left side of the HVAC air supply housing 1. A quick-disassembly filter assembly 3 is fixedly installed on the inner wall of the HVAC air supply housing 1 and is located at the connection between the air inlet pipe 4 and the HVAC air supply housing 1. The quick-disassembly filter assembly 3 includes a second filter plate frame 206 fixedly installed on the inner wall of the HVAC air supply housing 1. A worm 210 is rotatably installed on the bottom side inside the HVAC air supply housing 1. A motor bracket 208 is fixedly installed on the top of the HVAC air supply housing 1. A motor 209 is fixedly installed inside the motor bracket 208, and the output shaft of the motor 209 extends to the inside of the HVAC air supply housing 1 and is fixedly connected to one end of the worm 210. A rotating shaft 201 is rotatably installed on the inner wall of the HVAC air supply housing 1. A turbine 202 is fixedly installed at the end of the rotating shaft 201, and the worm 210 meshes with the turbine 202. A rotating center block 203 is fixedly installed on the outer surface of the turbine 202. A first filter plate frame 204 is fixedly installed on the side of the rotating center block 203. Placement grooves 212 are formed inside the second filter plate frame 206 and the first filter plate frame 204. A first filter plate 205 and a second filter plate 207 are respectively slidably installed inside the placement grooves 212. A quick-disassembly filter assembly 3 is fixedly installed on the front of the first filter plate frame 204 and the second filter plate frame 206. A sensor 211 is fixedly installed on the inner top of the HVAC air supply housing 1. A connection pipe 10 is fixedly installed on the right side of the HVAC air supply housing 1 and is in communication with each other.

[0028] When the connecting pipe 10 is connected to the driving device in the HVAC, external air enters the air supply housing 1 of the HVAC. Then, when the sensor 211 detects that after the HVAC operates at a high load, the pollutants intercepted by the first filter plate 205 and the second filter plate 207 accumulate continuously, further hindering air circulation and causing a significant reduction in ventilation efficiency. After the ventilation efficiency has decreased to a certain extent, the motor 209 will be controlled to start running, which will drive the worm 210 to start rotating. When the worm 210 starts rotating, it will drive the turbine 202 to start rotating through meshing. When the turbine 202 starts rotating, it will drive the rotating center block 203 to start rotating. When the rotating center block 203 starts rotating, it will drive the first filter plate frame 204 to start rotating. And since the upper part of the first filter plate frame 204 is fixedly connected to the center of the rotating center block 203 and will not touch the second filter plate frame 206 during rotation, when the rotating center block 203 starts rotating, it will drive the first filter plate 205 inside the first filter plate frame 204 to start rotating. When the first filter plate 205 rotates to be perpendicular to the second filter plate 207, it stops rotating, so that only the second filter plate 207 conducts filtration and ventilation, effectively increasing the ventilation volume. Then, through the connecting pipe 10, air is introduced into the room. Thus, due to the increased air intake efficiency, the HVAC can maintain the established air treatment capacity, certain reduce the operating load. At the same time, the sensor 211 will issue an alarm to prompt the staff to replace the second filter plate 207 and the first filter plate 205 in a timely manner.

[0029] When the system monitors that the sensor 211 detects that the accumulation of pollutants on the first filter plate 205 and the second filter plate 207 and the decrease in ventilation efficiency due to high-load operation, it intelligently starts the motor 209 to drive the transmission components, namely the turbine 202, the worm 210, the rotating center block 203, and the first filter plate frame 204. It ingeniously realizes precise transmission through gear meshing. By rotating the first filter plate 205 to be perpendicular to the second filter plate 207, it switches to a single-filter filtration mode, effectively expanding the ventilation area, quickly increasing the ventilation volume, and ensuring stable and efficient air supply from the connecting pipe 10 to the room. This design can not only maintain the established air treatment capacity of the HVAC, but also reduce the equipment operating load, reduce energy consumption and mechanical wear, and extend the service life of the equipment. At the same time, the sensor 211 promptly issues an alarm to remind to replace the filter screen, avoiding secondary pollution or equipment failure caused by a dirty filter screen, ensuring indoor air quality, and realizing intelligent, efficient, and energy-saving ventilation management.

[0030] Among them, the quick-disassembly and quick-assembly filter assembly 3 includes a first L-shaped bracket 301 fixedly installed on the front surfaces of the first filter plate holder 204 and the second filter plate holder 206. A second L-shaped bracket 302 is fixedly installed at the distal end of the first L-shaped bracket 301 on the front surfaces of the first filter plate holder 204 and the second filter plate holder 206, and a fixing groove is provided inside the second L-shaped bracket 302. A roller 303 is rotatably installed inside the first L-shaped bracket 301. A limiting plate 304 is fixedly sleeved on the outer surface of the roller 303. A magnetic attraction convex block 305 is fixedly installed at the bottom side of the other end of the limiting plate 304, and the magnetic attraction convex block 305 is exactly magnetically attracted to the fixing groove provided inside the second L-shaped bracket 302. One side of the placement groove 212 is fixedly connected with an auxiliary assembly 6.

[0031] When the staff flips the limiting plate 304 outward by an external force, the magnetic attraction convex block 305 magnetically attracted in the fixing groove of the second L-shaped bracket 302 will be separated, so that the limiting force of the limiting plate 304 on the first filter plate 205 and the second filter plate 207 disappears, resulting in the first filter plate 205 and the second filter plate 207 being pushed outward by the elastic recovery action of the auxiliary assembly 6 and sliding out along the placement groove 212, thus facilitating the staff to quickly disassemble, assemble and maintain the first filter plate 205 and the second filter plate 207. The first filter plate 205 and the second filter plate 207 can be effectively limited by the limiting plate 304.

[0032] Through the magnetic attraction type limiting structure of the limiting plate 304 and the magnetic attraction convex block 305, the staff only needs to apply an external force to flip the limiting plate 304 to quickly release the fixing restriction on the first filter plate 205 and the second filter plate 207. With the elastic recovery action of the auxiliary assembly 6, the components can slide out automatically, and disassembly can be completed without complex tools, significantly improving the maintenance efficiency. At the same time, during normal use, the limiting plate 304 can reliably limit and fix the first filter plate 205 and the second filter plate 207, ensuring the stable operation of the components, preventing loosening and displacement. This design takes into account both the stability of the equipment operation and the convenience of maintenance, effectively reducing the maintenance difficulty and time cost, and providing guarantee for the continuous and efficient operation of the equipment.

[0033] Among them, the auxiliary assembly 6 includes a spring 601 fixedly connected to one side of the placement groove 212. The other end of the spring 601 is fixedly connected with a connecting plate 602, and the other side surface of the connecting plate 602 abuts against the first filter plate 205, and the diameter of the connecting plate 602 is smaller than the diameter of the placement groove 212.

[0034] When the limiting effect of the limiting plate 304 on the first filter plate 205 and the second filter plate 207 disappears, the connecting plate 602 will move outward under the elastic recovery effect of the spring 601. Then, due to the contact between the connecting plate 602 and the first filter plate 205 and the second filter plate 207, it can assist the first filter plate 205 and the second filter plate rack 206 to slide out a little along the placement groove 212, facilitating the staff to take out and replace them.

[0035] Through the ingenious structural linkage, the maintenance efficiency is greatly improved. After the limiting plate 304 releases the limitation on the first filter plate 205 and the second filter plate 207, the spring 601 drives the connecting plate 602 to move outward by virtue of its elastic recovery characteristics. By utilizing the contact relationship between the connecting plate 602 and the first filter plate 205 and the second filter plate 207, the two are pushed to slide out along the placement groove 212, making it unnecessary to disassemble laboriously or operate precisely for component replacement, reducing the maintenance difficulty. This automatic auxiliary removal mechanism reduces the manual operation intensity and avoids component damage caused by repeated disassembly and assembly.

[0036] Among them, a protective door 7 is installed on the front of the HVAC air supply housing 1 in an interactive manner. The protective door 7 and the HVAC air supply housing 1 are hinged by a hinge 8, and a handle 9 is fixedly installed on the front of the protective door 7.

[0037] By pulling the handle 9 outward with an external force, the handle 9 drives the protective door 7 to flip outward. At the same time, the hinge 8 provides a rotational support force for the protective door 7, facilitating the staff to replace the first filter plate 205 and the second filter plate 207.

[0038] Among them, a flow guide cover 11 is fixedly installed on the inner wall of the HVAC air supply housing 1, and the flow guide cover 11 is located at the connection between the air inlet pipe 4 and the HVAC air supply housing 1 and is wider on the left and narrower on the right.

[0039] Since the flow guide cover 11 is located at the connection between the air inlet pipe 4 and the HVAC air supply housing 1 and is wider on the left and narrower on the right, it is convenient to guide the external air entering through the air inlet pipe 4 into the filtration and adjustment assembly 2 for filtration, preventing unfiltered air from entering the room.

[0040] Among them, a protective grille 5 is fixedly installed at the end of the air inlet pipe 4, and the diameter of the protective grille 5 is equal to the diameter of the air inlet pipe 4.

[0041] By fixedly installing a protective grille 5 at the end of the air inlet pipe 4, the entering air can be preliminarily filtered through the protective grille 5, preventing larger particulate matter from entering the interior of the HVAC air supply housing 1.

[0042] Among them, the rotating center block 203 is fixedly installed at the center of the turbine 202, and the outer surface of the upper end of the first filter plate rack 204 is fixedly installed on the side of the rotating center block 203.

[0043] By fixedly installing the outer surface of the upper end of the first filter plate frame 204 on the side surface of the rotary center block 203, it can be avoided that the first filter plate frame 204 is blocked by other components when rotating, reducing the failure rate.

[0044] Among them, the handle 9 is in a C shape and is located in the middle of the outer surface of the protective door 7.

[0045] Since the handle 9 is in a C shape and is located in the middle of the outer surface of the protective door 7, it is convenient for the staff to flip the protective door 7 through the handle 9.

[0046] Working principle and usage process:

[0047] When the connecting pipe 10 is connected to the driving device in the HVAC, external air enters the inside of the HVAC air supply housing 1. Then, when the sensor 211 detects that after the HVAC operates at a high load, the pollutants intercepted by the first filter plate 205 and the second filter plate 207 continuously accumulate, further hindering air circulation and resulting in a significant reduction in ventilation efficiency. After the ventilation efficiency drops to a certain level, the motor 209 will be controlled to start running, driving the worm 210 to start rotating. When the worm 210 starts rotating, it will drive the turbine 202 to start rotating through meshing. When the turbine 202 starts rotating, it will drive the rotary center block 203 to start rotating. When the rotary center block 203 starts rotating, it will drive the first filter plate frame 204 to start rotating. And since the upper part of the first filter plate frame 204 is fixedly connected to the center of the rotary center block 203 and will not touch the second filter plate frame 206 during rotation, when the rotary center block 203 starts rotating, it will drive the first filter plate 205 inside the first filter plate frame 204 to start rotating. When the first filter plate 205 rotates to be perpendicular to the second filter plate 207, it stops rotating, so that only the second filter plate 207 conducts filtering ventilation, effectively increasing the ventilation volume. Then, air enters the room through the connecting pipe 10, so that the HVAC can maintain the established air treatment volume through the increased air intake efficiency, reducing the operation load to a certain extent. At the same time, the sensor 211 will send an alarm to enable the staff to replace the second filter plate 207 and the first filter plate 205 in time.

[0048] When the staff flips the limit plate 304 outward by an external force, the magnetic attraction bumps 305 magnetically attracted in the fixing grooves of the second L-shaped bracket 302 will be disengaged, so that the limiting force of the limit plate 304 on the first filter plate 205 and the second filter plate 207 disappears, and the elastic force recovery effect of the auxiliary assembly 6 is used to push the first filter plate 205 and the second filter plate 207 outwards along the placement groove 212, facilitating the staff to quickly disassemble, assemble and maintain the first filter plate 205 and the second filter plate 207. The limit plate 304 can effectively limit the first filter plate 205 and the second filter plate 207.

[0049] When the limit of the limit plate 304 on the first filter plate 205 and the second filter plate 207 disappears, it will drive the connecting plate 602 to move outwards through the elastic force recovery of the spring 601. Then, because the connecting plate 602 abuts against the first filter plate 205 and the second filter plate 207, it can assist the first filter plate 205 and the filter plate holder 206 of the second filter plate to slide outwards a little along the placement groove 212, facilitating the staff to take out and replace.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
