Abstract
Description
Technical Field
[0001] This utility model relates to the field of central air conditioning air intake components, specifically a fresh air intake component with a dustproof mesh. Background Technology
[0002] The fresh air inlet assembly is an important component of the fresh air system. It integrates the inlet shell, dust filter, filter components, seals, brackets or fasteners, and possibly noise reduction and control monitoring components. The dust filter, as the primary filtration layer, effectively filters dust and impurities in the air, ensuring the quality of the air entering the room and providing reliable protection for the fresh air system.
[0003] The existing fresh air intake assembly is an important component of the fresh air system, mainly responsible for introducing fresh outdoor air. When it is necessary to clean the dust filter in the fresh air intake assembly, the user needs to completely remove the entire intake panel and pull the dust filter out from the gap formed by the adjacent limit rod. This process is cumbersome and complicated, and often requires professional cleaning staff to come and clean it. This not only increases the cleaning cost, but also greatly reduces the ease of use of the fresh air intake assembly. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a fresh air inlet assembly with a dustproof screen to solve the technical problem that the entire air inlet plate needs to be disassembled when cleaning the dustproof screen, which is a rather cumbersome and complicated process.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fresh air inlet assembly with a dustproof mesh, including an air inlet frame, a mounting bracket at the bottom of the air inlet frame, an air inlet plate rotatably connected to one side of the mounting bracket via a rotating rod, a limiting plate rotatably connected to one side of the air inlet plate via a rotating shaft, a handle at the other end of the rotating shaft, a spring plate on one side of the top of the air inlet plate, a limiting plate on one side of the spring plate, and a pull rope between the air inlet plate and the air inlet frame.
[0006] By adopting the above technical solution, when users need to clean the dustproof net, they first need to turn the handle. This action will cause the limiting plate to rotate, thereby releasing the locking state between the air inlet plate and the mounting bracket. Subsequently, the air inlet plate rotates under the support of the rotating rod until it is limited to a specific position by the pull rope. At this time, the dustproof net can be easily removed from the gap formed between the air inlet plate and the limiting plate for cleaning.
[0007] Furthermore, the pull rope is provided in two sets, both of which are made of nylon rope, to limit the movement trajectory of the air inlet plate.
[0008] By adopting the above technical solution, the nylon rope has good wear resistance, tensile strength and corrosion resistance, which can ensure that the rope is not easy to break or age during long-term use, thereby stably restricting the movement trajectory of the air inlet plate.
[0009] Furthermore, a gap is formed between one side of the air inlet plate and the limiting plate, and the limiting plate is a rectangular structure, and there are multiple limiting plates arranged linearly at equal intervals.
[0010] By adopting the above technical solution, the disassembly and installation of the dustproof net are greatly facilitated. The width of this gap is moderate, which can ensure that the dustproof net can be easily removed from the gap, and will not allow external impurities to easily enter the fresh air system due to the gap being too large.
[0011] Furthermore, the inner side of the air inlet plate is engaged with the mounting bracket by a limiting piece to restrict the position of the air inlet plate.
[0012] By adopting the above technical solution, this locking mechanism not only ensures that the air inlet plate can fit tightly against the mounting bracket when closed, improving the sealing performance of the fresh air inlet assembly, but also ensures that the air inlet plate remains stable during rotation, avoiding problems such as poor air intake or noise caused by positional displacement.
[0013] Furthermore, a dustproof net is provided between the air inlet plate and the limiting plate, and the dustproof net is made of activated carbon filter material.
[0014] By adopting the above technical solutions, activated carbon filter materials have excellent adsorption performance, which can effectively filter out harmful substances such as dust, pollen, and bacteria in the air, ensuring that the fresh air entering the room is fresher and healthier.
[0015] Furthermore, the air inlet plate is composed of multiple panels connected by connecting columns, and air inlets are formed between adjacent panels.
[0016] By adopting the above technical solutions, the fresh air inlet components are made more flexible and versatile in structure, which not only facilitates processing and installation, but also allows for adjustment of the number and size of air inlets according to actual needs, meeting the ventilation requirements of different scenarios.
[0017] In summary, the present invention has the following main advantages:
[0018] This invention utilizes a pull rope, handle, and limiting plate. When the user needs to clean the dustproof net, simply twisting the handle causes the limiting plate to rotate, thus disengaging the air inlet plate from the mounting bracket. The air inlet plate then rotates to a certain position via a rotating rod, where it is limited by the pull rope. At this point, the user can easily remove the dustproof net from the gap between the air inlet plate and the limiting plate for cleaning. This process eliminates the need to disassemble the entire air inlet plate, greatly simplifying the cleaning process and reducing cleaning costs. Furthermore, when the cleaned dustproof net needs to be installed, the user simply needs to... The dust filter is inserted between the air inlet plate and the limiting plate through the gap, and the spring force of the spring plate limits its position. Then, the air inlet plate is rotated again by rotating the rod, and the limiting plate is rotated by turning the handle to achieve the engagement of the air inlet plate and the mounting bracket, thus completing the installation of the dust filter. This allows users to clean and install the dust filter themselves, which not only improves the ease of use of the fresh air inlet component, but also enhances its practicality. Through the tight cooperation of the rotating rod, handle, and limiting plate, the dust filter and air inlet plate can be quickly disassembled and installed, bringing great convenience to users.

[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] A fresh air inlet assembly with a dust filter, such as Figures 1-4 As shown, the system includes an air inlet frame 1, a mounting bracket 2 at the bottom of the air inlet frame 1, an air inlet plate 3 rotatably connected to one side of the mounting bracket 2 via a rotating rod 7, a limiting plate 10 rotatably connected to one side of the air inlet plate 3 via a rotating shaft, a handle 9 at the other end of the rotating shaft, a spring plate 6 on one side of the top of the air inlet plate 3, a limiting plate 5 on one side of the spring plate 6, and a pull rope 8 between the air inlet plate 3 and the air inlet frame 1. When the user needs to clean the dust filter 4, they first need to turn the handle 9, which will cause the limiting plate 10 to rotate, thereby releasing the engagement between the air inlet plate 3 and the mounting bracket 2. Subsequently, the air inlet plate 3 rotates under the support of the rotating rod 7 until it is limited to a specific position by the pull rope 8. At this time, the dust filter 4 can be easily removed from the gap formed between the air inlet plate 3 and the limiting plate 5 for cleaning. This process does not require disassembling the entire air inlet plate 3, which greatly simplifies the cleaning process, reduces cleaning costs, and improves ease of use.
[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4Two sets of pull ropes 8 are provided, both made of nylon rope, to limit the movement trajectory of the air inlet plate 3. The nylon rope has good wear resistance, tensile strength and corrosion resistance, which can ensure that the pull rope 8 is not easy to break or age during long-term use, thus stably limiting the movement trajectory of the air inlet plate 3. At the same time, the setting of two sets of pull ropes 8 further enhances the stability of the air inlet plate 3 during rotation, preventing it from deviating from the predetermined track due to external forces, ensuring the reliability and safety of the fresh air inlet component. In addition, the lightweight nature of the nylon rope also makes the pull rope 8 more flexible in operation, making it easier for users to clean and install the dustproof net 4, improving the ease of use.
[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A gap is formed between one side of the air inlet plate 3 and the limiting plate 5. The limiting plate 5 has a rectangular structure and multiple plates are arranged linearly at equal intervals. This provides great convenience for the disassembly and installation of the dustproof net 4. The width of this gap is moderate, which ensures that the dustproof net 4 can be easily removed from the gap, and prevents external impurities from easily entering the fresh air system due to the gap being too large. At the same time, the rectangular structure of the limiting plate 5 is not only structurally stable and easy to process, but also ensures a tighter fit with the air inlet plate 3, which improves the sealing performance of the fresh air inlet component and effectively prevents external dust, insects and other impurities from entering the room through the gap, thus ensuring the cleanliness of the indoor air and the comfort of the living environment.
[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The inner side of the air inlet plate 3 is engaged with the mounting bracket 2 by a limiting piece 10 to limit the position of the air inlet plate 3. This engaging mechanism not only ensures that the air inlet plate 3 can fit tightly against the mounting bracket 2 when closed, improving the sealing performance of the fresh air inlet assembly, but also makes the air inlet plate 3 stable during rotation, avoiding problems such as poor air intake or noise caused by positional deviation. At the same time, the engaging relationship between the limiting piece 10 and the mounting bracket 2 is easy to operate and maintain. Users can simply turn the handle 9 to open and close the air inlet plate 3, which greatly improves the ease of use and enhances the overall structural strength of the fresh air inlet assembly, extending its service life.
[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4A dustproof net 4 is installed between the air inlet plate 3 and the limiting plate 5. The dustproof net 4 is made of activated carbon filter material. Activated carbon filter material has excellent adsorption performance and can effectively filter out harmful substances such as dust, pollen, and bacteria in the air, ensuring that the fresh air entering the room is fresher and healthier. At the same time, activated carbon filter material also has good air permeability and durability, and can maintain a stable filtration effect during long-term use, reducing the frequency of replacing the dustproof net 4 and the maintenance cost. In addition, the easy disassembly of the dustproof net 4 also allows users to easily clean and replace it, further improving the practicality of the fresh air inlet component and user satisfaction.
[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The air inlet panel 3 is composed of multiple panels connected by connecting columns, with air inlets formed between adjacent panels. This makes the fresh air inlet assembly more flexible and versatile in structure, not only facilitating processing and installation, but also allowing the number and size of air inlets to be adjusted according to actual needs, meeting the ventilation requirements of different scenarios. At the same time, the air inlets formed between adjacent panels ensure sufficient airflow without causing excessive external noise or dust to enter the room due to excessively large air inlets. The combination of multiple panels also enhances the overall aesthetics and decoration of the fresh air inlet assembly, making it more in line with the decoration style and aesthetic needs of modern homes.
[0034] The implementation principle of this utility model is as follows: When it is necessary to clean the dustproof net 4, first turn the handle 9 to rotate the limiting plate 10, thereby causing the air inlet plate 3 and the mounting bracket 2 to lose their engagement. Then, the air inlet plate 3 is rotated by the rotating rod 7. After rotating to a certain extent, the pull rope 8 limits the air inlet plate 3. At this time, the dustproof net 4 can be removed from the gap formed between one side of the air inlet plate 3 and the limiting plate 5. Then, the dustproof net 4 is cleaned. During this operation, when cleaning the dustproof net, the user does not need to completely remove the entire air inlet plate. He only needs to turn the handle 9. This avoids the need for professional cleaning staff to come to the door for cleaning during traditional cleaning. It not only reduces the cleaning cost but also simplifies the cleaning process and greatly improves the ease of use of the fresh air inlet component.
[0035] When installing the cleaned dustproof net 4, first insert the dustproof net 4 into the gap formed between the air inlet plate 3 and the limiting plate 5 through one side of the air inlet plate 3. Use the elasticity of the spring plate 6 to limit the dustproof net 4. Then, the air inlet plate 3 is rotated by the rotating rod 7. When it is rotated to a certain position, the user turns the handle 9 again to make the limiting plate 10 rotate, thereby realizing the engagement between the air inlet plate 3 and the mounting bracket 2, thus completing the installation of the dustproof net 4. Through the cooperation of the rotating rod 7, the handle 9, and the limiting plate 10, the dustproof net 4 and the air inlet plate 3 can be quickly disassembled and installed. Users can clean the dustproof net themselves, reducing the cost of on-site cleaning by cleaning professionals, thereby improving the practicality of the fresh air inlet component.
