Description

Technical Field

[0001] This utility model relates to the field of fresh air intake purification technology, and in particular to a multi-layer filter quick-release fresh air intake purification component. Background Technology

[0002] Fresh air intake purification refers to the filtration and purification of fresh air entering the room through various technologies and equipment to improve indoor air quality. It is an independent air handling system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air unit and duct fittings. The fresh air unit purifies outdoor air and introduces it into the room, while the indoor air is exhausted through the ducts.

[0003] Multi-layer filter quick-release fresh air intake purification components typically include a pre-filter, a HEPA filter layer, an activated carbon filter layer, and a post-filter. The combination of multiple filters can filter and adsorb various pollutants in the air in a multi-level and all-round way, effectively removing dust, pollen, smoke, bacteria, viruses, and harmful gases, greatly improving indoor air quality and providing people with a healthy and comfortable breathing environment.

[0004] In existing technologies, outdoor air enters through the air inlet of a fresh air system. First, it passes through a pre-filter in a multi-layer quick-release fresh air intake purification component, which filters out larger particles. Next, the air passes through an antibacterial layer to inhibit bacteria. Then, it enters a HEPA filter layer for fine filtration of fine particulate pollutants. Following this, it passes through an activated carbon filter layer to adsorb harmful gases and odors. Finally, after being filtered again by a post-filter, the clean air enters the room through the air outlet, thus purifying outdoor air and providing fresh, clean air indoors. However, insufficient sealing between the multiple layers of filters can lead to decreased purification efficiency. Multi-layer stainless steel filters wrap the filter edges with first and second edging, have internal grooves for embedding fasteners, and have mounting holes that match the mounting grooves to ensure a tight fit between the filter and the mounting carrier, improving sealing and corrosion resistance. However, issues remain, such as plastic clips cracking due to repeated insertion and removal leading to sealing failure, and metal connectors oxidizing and rusting, increasing disassembly resistance and even causing jamming. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layer filter quick-release fresh air intake purification component, which aims to improve the problems in the prior art where plastic buckles crack due to repeated insertion and removal, leading to sealing failure, and metal connectors rust due to oxidation, increasing disassembly resistance, or even jamming.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-layer filter quick-release fresh air intake purification component, including a pre-filter layer, a high-efficiency filter layer installed on top of the pre-filter layer, a uniform air distribution mesh installed on top of the high-efficiency filter layer, a fixing mechanism installed on the outer wall of the pre-filter layer and the uniform air distribution mesh, the fixing mechanism being used to fix the structure, and multiple vibration damping mechanisms installed at equal intervals at the bottom of the uniform air distribution mesh, the vibration damping mechanisms being used to reduce the vibration impact on the structure; the fixing mechanism includes a fixing frame, the fixing frame being fixedly connected to the outer wall of the pre-filter layer, fixing posts being fixedly connected to the four corners of the top of the fixing frame, and multiple locking blocks being rotatably connected at equal intervals on the inner wall of the fixing frame, the outer wall of the locking blocks being provided with locking grooves.

[0007] As a further description of the above technical solution:

[0008] A fixing plate is fixedly connected to the outer wall of the uniform air distribution net. Multiple limiting grooves are equally spaced on the outer wall of the fixing plate. A limiting groove is opened in the middle of the outer wall of the fixing plate. The card block is slidably connected to the inner wall of the limiting groove. An installation component is installed on the inner wall of the limiting groove and the card groove.

[0009] As a further description of the above technical solution:

[0010] The mounting assembly includes bolts, which are installed on the inner walls of the limiting groove and the slot. Multiple mounting plates are threaded to the left and right sides of the outer wall of the bolts, and the mounting plates are threaded to the inner walls of the fixing column.

[0011] As a further description of the above technical solution:

[0012] The vibration damping mechanism includes a fixed block, which is equidistantly fixed to the bottom wall of the wind distribution net, and a rotating shaft is rotatably connected to the inner bottom of the fixed block.

[0013] As a further description of the above technical solution:

[0014] A pressure block is rotatably connected to the outer wall of the rotating shaft, and a fixing rod is fixedly connected to the middle of the inner wall of the fixing block. The pressure block is slidably connected to the outer wall of the fixing rod.

[0015] As a further description of the above technical solution:

[0016] A limit ring is fixedly connected to the middle of the outer wall of the fixing rod, and a spring is installed on the left side of the outer wall of the fixing rod.

[0017] As a further description of the above technical solution:

[0018] The top wall of the high-efficiency filter layer has multiple mounting slots at equal intervals, and a mesh box is installed on the inner wall of the mounting slot.

[0019] As a further description of the above technical solution:

[0020] Activated carbon is installed on the inner wall of the mesh box, and a cover plate is fixedly connected to the top wall of the mesh box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, after the pre-filter layer, high-efficiency filter layer and uniform air mesh are installed together, the locking block on the outer wall of the fixed frame is rotated so that the locking block is inserted into the limiting groove two. At this time, the locking groove on the outer wall of the locking block is flush with the limiting groove one. Then, the mounting plate is placed into the locking groove and the limiting groove one. Then, the bolts are aligned with the threaded holes on the left and right sides of the outer wall of the mounting plate. The mounting plate and the fixing column are fixed together with the bolts to form a stable connection, which can prevent loosening after installation. The operation is convenient and easy to install and disassemble.

[0023] 2. In this utility model, the fixing blocks are equidistantly installed on the bottom wall of the uniform wind net. When the internal structure is vibrated, it will hit the pressure block, causing the pressure block to rotate on the outer wall of the rotating shaft. The upper end of the pressure block slides backward on the outer wall of the fixing rod, thereby compressing the spring. When the spring is vibrated, it will produce elastic deformation, absorb and buffer the vibration energy, further improve the vibration resistance of the structure, and also absorb some noise. This will prevent the parts from loosening, wearing or even being damaged due to long-term vibration, and extend the service life of the equipment. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a multi-layer filter quick-release fresh air intake purification component, including a pre-filter layer 9, a high-efficiency filter layer 8 installed on the top of the pre-filter layer 9, a uniform air distribution mesh 1 set on the top of the high-efficiency filter layer 8, a fixing mechanism 2 installed on the outer wall of the pre-filter layer 9 and the uniform air distribution mesh 1, the fixing mechanism 2 being used to fix the structure, and multiple vibration damping mechanisms 3 equidistantly installed at the bottom of the uniform air distribution mesh 1, the vibration damping mechanisms 3 being used to reduce the vibration impact on the structure; the fixing mechanism 2 includes a fixing frame 205, the fixing frame 205 being fixedly connected to the outer wall of the pre-filter layer 9, and the top of the fixing frame 205 having four bends Fixed posts 204 are fixedly connected at each corner. Multiple locking blocks 206 are equidistantly rotatably connected to the inner wall of the fixed frame 205. The outer wall of the locking blocks 206 has a locking groove 207. A fixed plate 201 is fixedly connected to the outer wall of the uniform air distribution net 1. Multiple limiting grooves 203 are equidistantly opened on the outer wall of the fixed plate 201. A limiting groove 202 is opened in the middle of the outer wall of the fixed plate 201. The locking blocks 206 are slidably connected to the inner wall of the limiting groove 203. An installation component 208 is installed on the inner wall of the limiting groove 202 and the locking groove 207. The installation component 208 includes bolts 2082, which are installed on... Multiple mounting plates 2081 are threadedly connected to the inner walls of the limiting groove 202 and the slot 207, and to the left and right sides of the outer wall of the bolt 2082. The mounting plates 2081 are threadedly connected to the inner wall of the fixing column 204. During installation, the pre-filter layer 9, the high-efficiency filter layer 8, and the uniform air distribution mesh 1 must first be stacked and assembled in sequence. After completing this step, the next operation involves rotating the locking block 206 on the outer wall of the fixing frame 205 to ensure that the locking block 206 can smoothly embed into the limiting groove 203. Once the locking block 206 is correctly embedded into the limiting groove 203, the slot on the outer wall of the locking block 206 will... 207 will be on the same horizontal line as the limiting groove 202, that is, in a flush state. At this time, the mounting plate 2081 needs to be placed between the slot 207 and the limiting groove 202. To ensure the stability and firmness of the mounting plate 2081, the bolts 2082 need to be aligned with the threaded holes on the left and right sides of the outer wall of the mounting plate 2081, and the mounting plate 2081 and the fixing post 204 need to be tightly fixed with the bolts 2082. This design not only ensures the stability of the connection and prevents the loosening that may occur after installation, but also makes the whole operation simple and quick, greatly improving the efficiency of installation and disassembly.

[0033] Specifically, after installing the pre-filter layer 9, the high-efficiency filter layer 8, and the uniform air distribution mesh 1 together, rotate the locking block 206 on the outer wall of the fixed frame 205 so that the locking block 206 is engaged in the limiting groove 203. At this time, the locking groove 207 on the outer wall of the locking block 206 is flush with the limiting groove 202. Then, place the mounting plate 2081 into the locking groove 207 and the limiting groove 202. Align the bolts 2082 with the threaded holes on the left and right sides of the outer wall of the mounting plate 2081 and use the bolts 2082 to fix the mounting plate 2081 and the fixing post 204 together to form a stable connection. This can prevent loosening after installation, and the operation is convenient, making installation and disassembly easy.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The vibration damping mechanism 3 includes a fixed block 301, which is equidistantly fixed to the bottom wall of the uniform air distribution net 1. A rotating shaft 305 is rotatably connected to the inner bottom of the fixed block 301. A pressure block 304 is rotatably connected to the outer wall of the rotating shaft 305. A fixed rod 303 is fixedly connected to the middle of the inner wall of the fixed block 301. The pressure block 304 is slidably connected to the outer wall of the fixed rod 303. A limit ring 306 is fixedly connected to the middle of the outer wall of the fixed rod 303. A spring 302 is installed on the left side of the outer wall of the fixed rod 303. To improve the vibration resistance of the structure and absorb some noise, the fixed block 301 is uniformly... Installed on the bottom wall of the uniform wind net 1, when the internal structure vibrates due to various factors, the vibration will be transmitted to the pressure block 304, causing it to rotate on the outer wall of the rotating shaft 305. The upper end of the pressure block 304 slides backward on the outer wall of the fixed rod 303. This sliding action causes the spring 302 to be compressed. The spring 302 undergoes elastic deformation under the action of vibration. This deformation can effectively absorb and buffer vibration energy, thereby enhancing the vibration resistance of the entire structure. In addition, this design can also absorb some noise and prevent the loosening, wear and even damage of parts caused by long-term vibration, thereby extending the service life of the equipment.

[0035] Specifically, the fixing blocks 301 are equidistantly installed on the bottom wall of the uniform wind net 1. When the internal structure is vibrated, they will impact the pressure block 304, causing the pressure block 304 to rotate on the outer wall of the rotating shaft 305. The upper end of the pressure block 304 slides backward on the outer wall of the fixing rod 303, thereby compressing the spring 302. When the spring 302 is vibrated, it undergoes elastic deformation, absorbing and buffering vibration energy, further improving the structure's vibration resistance, and also absorbing some noise. This prevents components from loosening, wearing, or even being damaged due to long-term vibration, thus extending the service life of the equipment.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The top wall of the high-efficiency filter layer 8 is provided with multiple installation slots 7 at equal intervals. The inner wall of the installation slot 7 is provided with a mesh box 6. The inner wall of the mesh box 6 is provided with activated carbon 5. The top wall of the mesh box 6 is fixedly connected with a cover plate 4.

[0037] Specifically, activated carbon 5 is a material widely used in the field of air purification. It can effectively adsorb formaldehyde, odors and other gaseous pollutants in the air. In some products, activated carbon 5 is also coated with a photocatalyst. This special coating can further enhance the ability of activated carbon 5 to decompose harmful substances. The high-efficiency filter layer 8 uses multiple mechanisms such as physical interception and electrostatic adsorption to efficiently filter out tiny particles in the air. These particles often have bacteria, viruses and other microorganisms attached to them. The high-efficiency filter layer 8 can effectively intercept these microorganisms, thereby inhibiting their reproduction. In addition, this filter layer can also prevent dust from clogging the pores of activated carbon 5, which not only improves the filtration efficiency, but also extends the service life of activated carbon 5.

[0038] Working principle: During installation, the pre-filter layer 9, high-efficiency filter layer 8, and uniform air distribution mesh 1 must first be stacked and installed together. After completing this step, the next operation is to rotate the locking block 206 on the outer wall of the fixing frame 205 to ensure that the locking block 206 can smoothly engage in the limiting groove 203. When the locking block 206 is correctly engaged in the limiting groove 203, the locking groove 207 on the outer wall of the locking block 206 will be on the same horizontal line as the limiting groove 202, that is, flush. At this time, it is necessary to... Place the mounting plate 2081 between the slot 207 and the limiting slot 202. To ensure the stability and firmness of the mounting plate 2081, align the bolts 2082 with the threaded holes on the left and right sides of the outer wall of the mounting plate 2081, and use the bolts 2082 to firmly fix the mounting plate 2081 to the fixing post 204. This design not only ensures the stability of the connection and prevents loosening that may occur after installation, but also makes the whole operation simple and quick, greatly improving the efficiency of installation and disassembly.

[0039] To further enhance the structure's vibration resistance and absorb some noise, the fixing blocks 301 are equidistantly installed on the bottom wall of the uniform wind net 1. When the internal structure is vibrated for various reasons, these vibrations are transmitted to the pressure block 304. The pressure block 304 rotates on the outer wall of the rotating shaft 305, and its upper end slides backward on the outer wall of the fixing rod 303. This sliding action causes the spring 302 to be compressed. When the spring 302 is vibrated, it will produce elastic deformation. This elastic deformation can effectively absorb and buffer vibration energy, thereby further improving the vibration resistance of the entire structure. At the same time, this design can also absorb some noise and avoid loosening, wear or even damage of components due to long-term vibration, thereby extending the service life of the equipment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
