Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically a modular combined air filter. Background Technology

[0002] Air filters are needed when indoor air quality is poor, outdoor environmental pollution is severe, or there is industrial pollution in the surrounding area. They can remove harmful substances in the air through physical interception and adsorption, thereby filtering pollutants, impurities, and particles and improving air quality.

[0003] Current air filters have fixed filtration configurations, generally containing only basic HEPA filters and activated carbon. They cannot be adjusted for different pollution scenarios. Furthermore, their high degree of structural integration and non-disassembly of components mean that if one component fails, the entire unit must be disassembled for repair, or even scrapped due to the non-disassembly structure. This no longer meets people's needs. Therefore, we propose a new type of modular combined air filter to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a modular combined air filter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular combined air filter, including an integrated frame, and further comprising...

[0006] The first filter module, the second filter module, the third filter module and the fourth filter module are installed sequentially at the top of the integrated frame, and side assembly seats are fixed on both sides of the integrated frame.

[0007] A telescopic cylinder is fixed to the outer wall of the side assembly base. The output end of the telescopic cylinder is connected to a drive arm. A movable air intake plate is fixed between adjacent drive arms. A pressure sensor is installed on the top of the movable air intake plate.

[0008] The first, second, third, and fourth filter modules are respectively equipped with a pre-filter nylon mesh, a HEPA filter, a photocatalytic catalytic mesh, and an activated carbon adsorption layer. The outer walls of the pre-filter nylon mesh, HEPA filter, photocatalytic catalytic mesh, and activated carbon adsorption layer are all fixed with internal inserts. A UV lamp is installed on the internal insert at one end of the photocatalytic catalytic mesh.

[0009] The integrated frame is equipped with a PLC controller and a battery in sequence. Inside the integrated frame, near the PLC controller, there is a fixed air outlet plate. At the bottom of the fixed air outlet plate, there is an exhaust pipe. A flow control valve is installed on the exhaust pipe.

[0010] A variable frequency fan is installed at the bottom of the integrated frame by screws, and a flange is installed between the input end of the variable frequency fan and the exhaust pipe.

[0011] Furthermore, casters are installed on the bottom of both sides of one end of the integrated frame, and an operating handle is provided on the integrated frame above the casters.

[0012] Furthermore, the first filter module, the second filter module, the third filter module, and the fourth filter module are all slidably connected to the inner insert frame. Screws are evenly arranged at the top edge of the inner insert frame, and a rubber sealing layer is vulcanized and connected to the outer side wall of the inner insert frame.

[0013] Furthermore, hollow sealing docking plates are fixed at both ends of the first filter module, the second filter module, the third filter module, and the fourth filter module, as well as at one end of the moving air inlet plate and the fixed air outlet plate, and rubber sealing rings are evenly arranged on the hollow sealing docking plates.

[0014] Furthermore, the UV lamp and the variable frequency fan are respectively connected to the PLC controller by threaded wires.

[0015] Furthermore, two side assembly seats are provided, and a sliding cavity is provided on the side of the side assembly seat near the first filter module.

[0016] Furthermore, the bottom sides of the first filter module, the second filter module, the third filter module and the fourth filter module are all provided with sliding feet that match the sliding cavity.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This modular combined air filter optimizes its structure by incorporating a first filter module, among others. Users can selectively insert the sliding feet of the first, second, third, and fourth filter modules into the sliding cavity according to their actual air filtration needs. Then, activating the telescopic cylinders on the two side mounting bases automatically moves the drive arms at their output ends. This causes the fixed movable air intake plate between the two drive arms to move towards the filter structure, compressing the corresponding number of filter modules. This ensures that the hollow sealing mating plates pre-reserved on the first, second, third, and fourth filter modules, the movable air intake plate, and the fixed air outlet plate are pressed together, forming a complete multi-stage filtration mechanism. Furthermore, by designing the filter structure as a modular unit that allows for quick and easy replacement, greater flexibility is achieved. On the other hand, the first, second, third, and fourth filter modules... The four-filter module contains a pre-filter nylon mesh, a HEPA filter, a UV lamp, a photocatalytic catalytic mesh, and an activated carbon adsorption layer. These components sequentially intercept large particulate impurities such as dust, hair, and fibers from the air; filter fine particles such as PM2.5, bacteria, and allergens; catalyze the decomposition of aldehydes such as formaldehyde and acetaldehyde; and adsorb benzene, TVOC, and odors. Combined with a modular assembly structure, users can adjust the filtration efficiency by adding or removing modules. For example, in smog scenarios, the first, second, and fourth filter modules can be assembled on an integrated rack to achieve a pre-filter plus HEPA and activated carbon combination. For newly renovated homes, the first, second, third, and fourth filter modules can be assembled on an integrated rack to achieve a combination of pre-filter plus HEPA, formaldehyde decomposition, and activated carbon.

[0028] The first filter module 20, the second filter module 19, the third filter module 18 and the fourth filter module 10 are installed sequentially at the top of the integrated frame 1. Side assembly seats 2 are fixed on both sides of the integrated frame 1.

[0029] A telescopic cylinder 7 is fixed to the outer wall of the side assembly seat 2. The output end of the telescopic cylinder 7 is connected to a drive arm 28. A movable air intake plate 12 is fixed between adjacent drive arms 28. A pressure sensor 11 is installed at the top of the movable air intake plate 12.

[0030] Two side assembly seats 2 are provided, and a sliding cavity 27 is provided on the side of the side assembly seat 2 closest to the first filter module 20;

[0031] The bottom sides of the first filter module 20, the second filter module 19, the third filter module 18 and the fourth filter module 10 are all provided with sliding feet 26 that match the sliding cavity 27.

[0032] Hollow sealing docking plate 25 is fixed at both ends of the first filter module 20, the second filter module 19, the third filter module 18, the fourth filter module 10, as well as at one end of the moving air intake plate 12 and the fixed air outlet plate 8. Rubber sealing rings are evenly arranged on the hollow sealing docking plate 25.

[0033] In use, users can selectively insert the sliding feet 26 of the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 into the sliding cavity 27 according to their actual air filtration needs. Then, the telescopic cylinders 7 on the two side mounting bases 2 are activated, which drive the drive arms 28 at their output ends to move automatically. This can drive the moving air intake plate 12 fixed between the two drive arms 28 to move towards the filter structure, pressing the corresponding number of filter modules. This makes the hollow sealing docking plate 25 reserved on the first filter module 20, the second filter module 19, the third filter module 18, the fourth filter module 10, the moving air intake plate 12, and the fixed air outlet plate 8 pressed together to form a complete multi-stage filtration mechanism. Furthermore, by setting the filter structure as a modular unit that is easy to quickly replace, the flexibility is greater.

[0034] The first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 are respectively equipped with a pre-filter nylon mesh 21, a HEPA filter 22, a photocatalytic catalytic mesh 24, and an activated carbon adsorption layer 16. The outer walls of the pre-filter nylon mesh 21, the HEPA filter 22, the photocatalytic catalytic mesh 24, and the activated carbon adsorption layer 16 are all fixed with an inner insert bracket 17. A UV lamp 23 is installed on the inner insert bracket 17 at one end of the photocatalytic catalytic mesh 24.

[0035] In use, the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 are respectively equipped with a pre-filter nylon mesh 21, a HEPA filter 22, a UV lamp 23, a photocatalytic catalytic mesh 24, and an activated carbon adsorption layer 16. These components can sequentially intercept large particulate impurities such as dust, hair, and fibers in the air, filter fine particles such as PM2.5, bacteria, and allergens, catalyze the decomposition of aldehydes such as formaldehyde and acetaldehyde, and adsorb benzene, TVOC, and odors. With these four functions, combined with the modular assembly structure, users can adjust the filtration efficiency by adding or removing modules. For example, for smog scenarios, the first filter module 20, the second filter module 19, and the fourth filter module 10 can be assembled on the integrated frame 1 to achieve a modular combination of pre-filter, HEPA, and activated carbon. For new house renovations, the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 can be assembled on the integrated frame 1 to achieve a combination of pre-filter, HEPA, formaldehyde decomposition module, and activated carbon.

[0036] A PLC controller 13 and a battery 14 are installed sequentially on the integrated frame 1. A fixed air outlet plate 8 is fixed inside the integrated frame 1 near the PLC controller 13. An exhaust pipe 5 is fixed at the bottom of the fixed air outlet plate 8. A flow control valve 6 is installed on the exhaust pipe 5.

[0037] The bottom of the integrated frame 1 is fitted with a variable frequency fan 3 by screws. A flange 4 is installed between the input end of the variable frequency fan 3 and the exhaust pipe 5 to facilitate the independent disassembly and assembly of the variable frequency fan 3.

[0038] Casters 15 are installed on the bottom of both sides of the integrated frame 1, and an operating handle is provided on the integrated frame 1 above the casters 15 to facilitate flexible movement.

[0039] The first filter module 20, the second filter module 19, the third filter module 18 and the fourth filter module 10 are all slidably connected to the inner insert frame 17. Screws are evenly arranged at the top edge of the inner insert frame 17, and a rubber sealing layer is vulcanized on the outer wall of the inner insert frame 17.

[0040] In use, the user can use the inner insert bracket 17 fixed on the pre-filter nylon mesh 21, HEPA filter 22, photocatalytic catalytic mesh 24 and activated carbon adsorption layer 16 to position the corresponding first filter module 20, second filter module 19, third filter module 18 and fourth filter module 10 with the screw locking structure, so as to facilitate the independent disassembly and cleaning of the filter unit.

[0041] The UV lamp 23 and the variable frequency fan 3 are connected to the PLC controller 13 by threaded wires 9.

[0042] The working principle of this utility model is as follows: First, the user can grasp the handle on the integrated frame 1 and tilt it so that the casters 15 touch the ground. After moving the device to a suitable operating position, it is placed flat. During actual operation, the variable frequency fan 3 starts, and in conjunction with the flow control valve 6, the exhaust flow is regulated. At the same time, the user can selectively insert the sliding feet 26 of the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 into the sliding cavity 27 according to actual air filtration needs. Then, the telescopic cylinders 7 on the two side mounting bases 2 are activated, which drives the drive arms 28 at their output ends to move automatically. This can drive the two drive arms 28. The fixed movable air intake plate 12 moves towards the filter structure, pressing the corresponding number of filter modules together. This causes the first filter module 20, the second filter module 19, the third filter module 18, the fourth filter module 10, the movable air intake plate 12, and the hollow sealing docking plate 25 pre-reserved on the fixed air outlet plate 8 to be pressed together, forming a complete multi-stage filtration mechanism. Furthermore, by setting the filter structure as a modular unit that is easy to quickly replace, greater flexibility is achieved. Additionally, the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 are respectively equipped with a pre-filter nylon mesh 21, a HEPA filter 22, and a U... The UV lamp 23, photocatalytic mesh 24, and activated carbon adsorption layer 16 sequentially intercept large particulate impurities such as dust, hair, and fibers in the inhaled air; filter fine particles such as PM2.5, bacteria, and allergens; catalyze the decomposition of aldehydes such as formaldehyde and acetaldehyde; and adsorb benzene, TVOC, and odors. These four functions, combined with a modular assembly structure, allow users to adjust the filtration efficiency by adding or removing modules. For example, in smog scenarios, the first filter module 20, the second filter module 19, and the fourth filter module 10 can be assembled on the integrated frame 1 to achieve a modular combination scheme of pre-filtration plus HEPA and activated carbon. For newly renovated homes, the first filter module 20, the second filter module 19, the third filter module 18, and the fourth filter module 10 can be assembled on the integrated frame 1 to achieve a combination of pre-filtration, HEPA filter, formaldehyde decomposition module, and activated carbon. Furthermore, users can utilize the internal insertion brackets 17 fixed on the pre-filtration nylon mesh 21, HEPA filter 22, photocatalytic catalytic mesh 24, and activated carbon adsorption layer 16 to position and insert the corresponding first filter module 20, second filter module 19, third filter module 18, and fourth filter module 10, along with the screw locking structure, to facilitate the independent disassembly and cleaning of the filter units.
