Description

Technical Field

[0001] This utility model relates to the field of fresh air purification technology, and in particular to a fresh air purification device with a multi-layer filtration structure for indoor central air conditioning. Background Technology

[0002] Fresh air purification is an air treatment technology that combines indoor ventilation and air purification. Its core is to introduce fresh outdoor air into the room through a mechanical system, while filtering and purifying the introduced air (such as removing particulate matter, harmful gases, microorganisms, etc.) and expelling the polluted indoor air, thereby continuously improving indoor air quality and maintaining a healthy and comfortable indoor environment.

[0003] With the development of modern architecture and the increasing demands of people for indoor environmental quality, indoor air quality has become an important factor affecting people's health and comfort. Traditional central air conditioning systems mainly focus on temperature regulation, while their air purification function is relatively limited. Especially in enclosed indoor environments, due to the lack of effective ventilation mechanisms, pollutants such as particulate matter, harmful gases, and microorganisms in indoor air are prone to accumulate, leading to a decline in air quality. This may in turn cause or aggravate health problems such as respiratory diseases and allergic reactions in residents. Therefore, there is a need for an indoor central air conditioning system with a multi-layer filtration structure for fresh air purification. Utility Model Content

[0004] The main purpose of this utility model is to provide an indoor central air conditioning system with a multi-layer filtration structure for fresh air purification, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fresh air purification device with a multi-layer filtration structure for indoor central air conditioning includes a filter box with two doors, two suction fans on the top of the filter box, an isolation mechanism for processing the air drawn in by the two suction fans, a filtration mechanism and a disinfection mechanism inside the filter box, and an air outlet extending outside the filter box from below the disinfection mechanism.

[0007] Preferably, the isolation mechanism includes a rectangular shell, which is installed on the filter box. The rectangular shell contains two isolation plates, each of which contains a spiral blade. Each of the spiral blades is equipped with a brush for cleaning the two isolation plates.

[0008] Preferably, the filtration mechanism includes four slide rails, which are respectively installed on the left and right sides inside the filter box. Each of the two slide rails on the same side is provided with a sliding slider. The opposing surfaces of the two sliders are provided with a primary filter, a medium filter, and a high-efficiency filter. Each slider is provided with a guide rail, and a cleaning brush for cleaning the primary filter is provided between the two guide rails.

[0009] Preferably, the primary filter is used to filter large particulate pollutants in the air drawn in by the suction fan, the medium-efficiency filter is used to filter medium particulate pollutants, and the high-efficiency filter is used to filter small particles.

[0010] Preferably, the disinfection mechanism includes a fixed plate, which is disposed inside the filter box. A circular shell is provided under the fixed plate, and a plurality of ultraviolet lamps are provided on the inner surface of the circular shell. A circular plate is provided between the circular shell and the fixed plate, and three oblique flow holes are provided on the circular plate to guide the air.

[0011] Preferably, the circular shell is further provided with an air outlet plate that discharges air into the air outlet. The circular plate and the air outlet plate are provided with rotating blades on their opposite surfaces, so that the rotating blades prolong the time the air stays in the circular shell.

[0012] Preferably, the fixing plate is used to fix the circular shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device employs a three-layer filtration structure consisting of a pre-filter, a medium-efficiency filter, and a high-efficiency filter. This allows for the sequential filtration of large, medium, and small particulate pollutants from the air, comprehensively removing pollutants of different sizes. This improves indoor air quality and thoroughly purifies the incoming air, meeting the high requirements for clean indoor air. The cleaning brush in the filtration mechanism can slide along a guide rail to clean impurities from the pre-filter. The cooperation between the slider and the rail facilitates the disassembly and deep cleaning of the filter, preventing a decrease in filtration efficiency due to long-term dirt accumulation, thus extending the filter replacement cycle and the overall lifespan of the device.

[0015] 2. The disinfection mechanism of this device guides air obliquely into the circular shell through the oblique flow holes on the circular plate. With the help of rotating blades, the air undergoes centrifugal motion inside the shell, which prolongs the contact time between the air and the ultraviolet lamp. This ensures that the ultraviolet light can fully destroy the DNA or RNA structure of microorganisms (bacteria, viruses, etc.) in the air, improve the thoroughness of disinfection and sterilization, and provide a safer air environment for the indoor environment.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1 and Figure 2 As shown, an indoor central air conditioning fresh air purification device with a multi-layer filtration structure includes a filter box 1, two doors 3 on the filter box 1, two suction fans 7 on the top of the filter box 1, an isolation mechanism 4 on the filter box 1 for processing the air drawn in by the two suction fans 7, a filtration mechanism 5 and a disinfection mechanism 6 respectively inside the filter box 1, and an air outlet 2 extending out of the filter box 1 below the disinfection mechanism 6.

[0025] This device uses a standard voltage for power supply, and its power supply operation is a conventional operation in existing technology, which will not be described in detail here.

[0026] The working process of this device is as follows:

[0027] First, install the device in the designated location. Then, connect the central air conditioning inlet and outlet 2. Next, start the two suction fans 7 to draw in outside air. The air drawn in by the suction fans 7 will first pass through the isolation mechanism 4, which isolates large floating objects in the air, such as plastic bags, paper, etc., to prevent these floating objects from being drawn into the suction fans 7 and ensure that the suction fans 7 can operate normally. When the two suction fans 7 are working, they will also drive the isolation mechanism 4 to move, so that the floating objects isolated by the isolation mechanism 4 will not continue to adhere to the isolation mechanism 4. This allows the suction fans 7 to deliver outside air to the filter box 1 normally. Then, the air will pass through the filter mechanism 5, which performs three layers of filtration to filter out particulate matter in the air, ensuring that the particulate matter in the air is completely isolated.

[0028] As described above, when the suction fan 7 is working, the staff simultaneously activates the disinfection mechanism 6. After the air is isolated by the filter mechanism 5, it enters the disinfection mechanism 6. At this time, the disinfection mechanism 6 causes the air to enter at an angle, making the air centrifugal flow within the disinfection mechanism 6. Then, the disinfection mechanism 6 disinfects the air, destroying the microorganisms in the air. The air then enters the air outlet 2 from the disinfection mechanism 6, and then enters the connected central air conditioning duct from the air outlet 2. This achieves multi-layer filtration of the air, purifies the indoor and outdoor air, and ensures the quality of indoor air.

[0029] In Example 2, further, in order to achieve the purpose of isolating the airborne particles drawn in by the suction fan 7 by the isolation mechanism 4, see [reference needed]. Figure 3 The isolation mechanism 4 includes a rectangular shell 41, which is installed on the filter box 1. The rectangular shell 41 has two isolation plates 44 inside, and each of the two isolation plates 44 has a spiral blade 43. Each of the two spiral blades 43 has a brush 42 for cleaning the two isolation plates 44.

[0030] In the above, when the suction fan 7 draws in outside air, the air first passes through two isolation plates 44, which isolate the floating objects in the air. Then the air enters the suction fan 7, preventing the floating objects from passing through the isolation plates 44 and entering the suction fan 7, thus ensuring that the suction fan 7 can work normally.

[0031] As described above, when the suction fan 7 is working, it will drive the spiral blade 43 to move together and rotate. When the spiral blade 43 rotates, it will drive the brush 42 to rotate. At this time, the brush 42 will clean the isolation plate 44, clean the floating objects attached to the isolation plate 44, and prevent the floating objects from affecting the air intake space of the isolation plate 44, so that the air can smoothly enter the filter box 1.

[0032] As described above, when the brush 42 rotates, after sweeping away the floating objects on the isolation plate 44, the rotation of the brush 42 will cause the floating objects to rotate as well. At this time, the floating objects will be thrown off the isolation plate 44 under the action of centrifugal force, thereby achieving the purpose of cleaning the floating objects.

[0033] Furthermore, in order to achieve the purpose of filtering air by the filtration unit 5, please refer to... Figure 4 The filter mechanism 5 includes four slide rails 57, which are respectively installed on the left and right sides inside the filter box 1. Each of the two slide rails 57 on the same side is provided with a sliding slider 54. The two sliders 54 are provided with a primary filter 53, a medium filter 55 and a high-efficiency filter 56 on their opposite sides. Each slider 54 is provided with a guide rail 52, and a cleaning brush 51 for cleaning the primary filter 53 is provided between the two guide rails 52.

[0034] Furthermore, the primary filter 53 is used to filter large particulate pollutants in the air drawn in by the suction fan 7, the medium-efficiency filter 55 is used to filter medium particulate pollutants, and the high-efficiency filter 56 is used to filter small particles.

[0035] In the above description, the pre-filter 53, medium-efficiency filter 55, and high-efficiency filter 56 are all bolted to the two sliders 54. When the suction fan 7 draws air into the filter housing 1, it first passes through the pre-filter 53, which performs preliminary filtration. The pre-filter 53 is made of non-woven fabric, nylon mesh, and other materials, which can effectively filter large particulate pollutants in the air, such as dust, hair, willow catkins, and insects. Then, the air passes through the pre-filter 53 and comes into contact with the medium-efficiency filter 55 for secondary filtration. The medium-efficiency filter 55 is made of materials such as glass fiber and polyester fiber, which can further filter medium particulate pollutants in the air, such as pollen and mold spores, to improve the air purification effect. Finally, the air enters the high-efficiency filter 56, which uses a HEPA filter and can filter out more than 99% of particles of 0.3 microns and smaller, including bacteria, viruses, PM2.5 and other fine particulate matter, thus completing the air filtration. The filtered air will then enter the disinfection unit 6 for disinfection treatment.

[0036] In the above description, the two sliders 54 are slidably mounted on the four slide rails 57. After a long time, the staff can open the two boxes 3. At this time, the suction fan 7 will no longer be working. Then the staff can remove the primary filter 53, the medium-efficiency filter 55, and the high-efficiency filter 56 from the slide rails 57 through the two sliders 54. At this time, the cleaning brush 51 and the two guide rails 52 will slide out of the filter box 1 along with the two sliders 54. After removal, the staff can pull and push the cleaning brush 51 back and forth, so that the cleaning brush 51 slides on the two guide rails 52 to clean the primary filter 53 and ensure the cleanliness of the surface of the primary filter 53.

[0037] As described above, since the medium-efficiency filter 55 and the high-efficiency filter 56 have higher cleanliness and disinfection capabilities, and impurities are all hidden inside the medium-efficiency filter 55 and the high-efficiency filter 56, when cleaning the medium-efficiency filter 55 and the high-efficiency filter 56, they need to be removed from the two sliders 54 and deeply cleaned separately to ensure that the medium-efficiency filter 55 and the high-efficiency filter 56 maintain a good filtration effect. After cleaning and drying, the staff will reinstall the medium-efficiency filter 55 and the high-efficiency filter 56 on the two sliders 54 using bolts. At this time, the sliders 54 will slide into the filter box 1 through the slide rail 57, so that the primary filter 53, the medium-efficiency filter 55 and the high-efficiency filter 56 can continue to filter the air and maintain a good filtration effect. Then, the staff will close and lock the box door 3. The locking method is a conventional operation of existing technology and will not be described in detail here.

[0038] Furthermore, in order to achieve the goal of disinfecting the air in the disinfection facility, please refer to... Figure 5 and Figure 6 The disinfection mechanism 6 includes a fixing plate 67, which is installed inside the filter box 1. A circular shell 61 is provided under the fixing plate 67. Several ultraviolet lamps 64 are provided on the inner surface of the circular shell 61. A circular plate 62 is provided between the circular shell 61 and the fixing plate 67. Three oblique flow holes 63 are opened on the circular plate 62 to guide the air.

[0039] Furthermore, the circular shell 61 is also provided with an air outlet plate 66 that discharges air into the air outlet 2. The circular plate 62 and the air outlet plate 66 are provided with rotating blades 65 on their opposite sides, so that the rotating blades 65 prolong the time that the air stays in the circular shell 61.

[0040] Furthermore, the fixing plate 67 is used to fix the circular shell 61.

[0041] In the above process, after the suction fan 7 starts working, the staff simultaneously turns on several ultraviolet lamps 64 to emit ultraviolet light. After the air is filtered by the filter mechanism 5, it enters the oblique flow holes 63 on the circular plate 62 through the air duct (the air duct is a structure well known to those skilled in the art, and this article does not impose too many limitations). At this time, the oblique flow holes 63, through their oblique hole design, cause the air to enter the circular shell 61 at an angle, causing the air to undergo centrifugal motion within the circular shell 61. This air then drives the rotating blades 65 to rotate between the circular plate 62 and the air outlet plate 66, causing the rotating blades 65 to drive the air to rotate within the circular shell 61, prolonging the time the air spends within the circular shell 61. Subsequently, the ultraviolet light emitted by the several ultraviolet lamps 64 disinfects the air, disinfecting microorganisms in the air. The air then flows from the several circular holes on the air outlet plate 66 to the air outlet 2, allowing the air outlet 2 to deliver the disinfected air to the air intake pipe of the central air conditioning system, thus completing the air filtration process.

[0042] The ultraviolet lamp 64 mentioned above is an artificial light source device that emits ultraviolet light. Its core principle is to generate electromagnetic waves with wavelengths between 100 nanometers and 400 nanometers by exciting a specific electric light source, and then use it for specific applications. The principle of air disinfection is to use ultraviolet light in the UVC band with wavelengths of 200-280 nanometers to penetrate the cells of bacteria, viruses and other microorganisms in the air, destroy their DNA or RNA structure, and make them lose their ability to reproduce, thereby reducing the concentration of microorganisms in the air. It can adopt the existing technology model: long strip ultraviolet curing lamp.

[0043] In addition, using this device can achieve an air purification level of 10 within the industry.

[0044] It should be noted that the specific installation method, circuit connection method, and control method of the suction fan 7 and ultraviolet lamp 64 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
