Description

Technical Field

[0001] This utility model relates to the field of dustproof technology for air conditioning units, specifically a non-woven fabric dustproof structure for the air inlet of an air conditioning unit. Background Technology

[0002] Currently, modular air conditioning units are widely used in building air conditioning, fresh air systems, and industrial ventilation applications. Their air inlets typically require dustproof devices to prevent dust, fibers, and impurities from entering the equipment and affecting heat exchange efficiency and air quality. Existing dustproof structures often use metal filters, detachable frames, or simple non-woven fabric filter layers, fixed to the surface of the air conditioning unit by screws, clips, or magnets.

[0003] In traditional solutions, a common structure is a combination of a metal protective frame and a filter, secured to the air intake of the air conditioning unit with screws. While this provides high stability, each time the filter is replaced or cleaned, tools are needed to remove the screws, making the process cumbersome and time-consuming, especially in confined server room environments, resulting in low maintenance efficiency.

[0004] Another common structure uses magnetic attraction to attach non-woven fabric or filter plates to the air inlet surface. This type of structure is relatively easy to install and remove, but the magnetic connection strength is limited. During long-term operation, the filter layer is prone to loosening or displacement due to vibration of the air conditioning unit or airflow impact, thereby reducing the dustproof effect and even causing secondary pollution.

[0005] Some structures use integrated filter elements or filter cloth directly embedded in the frame. Although the replacement cycle is long, they lack a quick disassembly and assembly design. Once the filter layer is severely contaminated, the entire filter can only be replaced, which increases operating costs.

[0006] In summary, the existing dustproof structures for air inlets of air conditioning units generally have the following problems: First, the connection between the protective frame and the filter layer mostly relies on screws or magnetic attraction, resulting in either inconvenient maintenance or insecure fixing; second, the filter layer is prone to dust accumulation during long-term operation, and the lack of a convenient and efficient quick disassembly and assembly mechanism makes it difficult to maintain and replace regularly; third, some structures lack stability and cannot balance filtration efficiency and installation firmness.

[0007] Therefore, there is an urgent need to propose a new non-woven fabric dustproof structure for the air inlet of an air conditioning unit, which can ensure the air filtration effect while enabling the rapid assembly and reliable locking of the protective frame to the surface of the air conditioning unit, so as to solve the technical problems of inconvenient maintenance and unstable connection in the existing technology. Utility Model Content

[0008] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0009] Therefore, the technical solution adopted by this utility model is as follows: a non-woven fabric dustproof structure for the air inlet of an air conditioning unit, including a protective frame, a non-woven filter layer, and fasteners. The non-woven filter layer is fixedly installed on the surface of the protective frame for primary filtration of the air entering the air conditioning unit. The fasteners include a connecting plate and several posts, with the posts arranged in a matrix on the surface of the connecting plate. Corresponding fasteners are provided on the surface of the protective frame and the air conditioning unit, and the posts of two fasteners interlock to achieve quick assembly and disassembly of the protective frame. Specifically, this structure can effectively improve the assembly and disassembly efficiency and fixing stability of the protective frame.

[0010] In a preferred embodiment, the column head is further configured such that a protrusion is provided at its top, and a retaining groove is formed on the surface of the bottom end of the protrusion, the retaining groove being adapted to the surface curvature of the protrusion. Specifically, this structural design enables a stable engagement between the protrusion and the retaining groove during insertion, improving the installation firmness of the protective frame.

[0011] In a preferred embodiment, the column head is further configured as follows: it has a symmetrical trumpet or hourglass shape, with its outer edge forming a guide surface to guide the protrusion to automatically align with the slot during assembly. Specifically, this structure improves assembly efficiency, makes installation smoother for operators, and avoids misalignment during insertion.

[0012] In a preferred embodiment, the connecting plate is further configured as follows: the column head is integrally injection molded onto the surface of the connecting plate, and the surface of the connecting plate is provided with mounting holes or an adhesive layer structure for positioning the fasteners on the protective frame and the surface of the air conditioning unit. This design ensures stable installation of the fasteners and improves the overall structural reliability.

[0013] In a preferred embodiment, the column heads are further configured such that there are no fewer than four rows, and they are evenly distributed along both the longitudinal and transverse directions. Specifically, this even distribution design ensures that the protective frame is subjected to uniform force when installed on the surface of the air conditioning unit, thereby preventing localized loosening and improving the overall protective effect.

[0014] In a preferred embodiment, the protrusion and the groove are further configured with an interference fit clearance, forming a friction lock after insertion. Specifically, the interference lock method prevents the protective frame from loosening due to vibration during the operation of the air conditioning unit, ensuring long-term operational stability.

[0015] In a preferred embodiment, the post head is further configured to be made of elastic plastic. Specifically, during insertion or removal, the post head can undergo moderate deformation between the protrusion and the groove, thereby improving insertion and removal smoothness, reducing component wear, and enhancing structural durability.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the combination structure of the protective frame and the non-woven filter layer effectively covers the air inlet of the air conditioning unit, so that the air entering the air conditioning unit is filtered by the non-woven filter layer first, which can significantly block dust and impurities in the air, ensure the cleanliness of the air supplied to the air conditioning system, thereby improving the working stability and service life of the air conditioning unit.

[0017] 2. In this utility model, the fastener is composed of a connecting plate and several column heads. The column heads are provided with protrusions and fastening grooves. They are interlocked to form an interference lock fit, which not only ensures the stable installation of the protective frame, but also facilitates quick disassembly and assembly by operators when maintaining or replacing the non-woven filter layer. Specifically, it achieves the technical effects of compact structure, reliable connection, convenient assembly and disassembly, and long-term durability. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a non-woven fabric dustproof structure for the air inlet of an air conditioning unit.

[0023] Combination Figures 1-6As shown, the present invention provides a non-woven fabric dustproof structure for the air inlet of an air conditioning unit, including a protective frame 100, a non-woven filter layer 200, and fasteners 300.

[0024] The protective frame 100 is a rectangular frame structure used for installation on the surface of the air inlet of the air conditioning unit. The non-woven filter layer 200 is fixedly installed on the surface of the protective frame 100, forming a dustproof layer covering the entire air inlet, so that the air entering the air conditioning unit is filtered by the non-woven filter layer 200, thereby blocking dust and impurities in the air and ensuring the cleanliness of the air conditioning system.

[0025] The fastener 300 includes a connecting plate 310 and a plurality of column heads 320, which are arranged in a matrix on the surface of the connecting plate 310. The protective frame 100 and the surface of the air conditioning unit are respectively provided with corresponding fasteners 300. The plurality of column heads 320 of two fasteners 300 are interlocked to enable quick assembly and disassembly of the protective frame 100, facilitating maintenance and replacement of the nonwoven filter layer 200.

[0026] In this embodiment, the top of the column head 320 is provided with a protrusion 321, and a snap-fit ​​groove 322 is formed on the surface of the bottom end of the protrusion 321. The snap-fit ​​groove 322 is adapted to the surface curvature of the protrusion 321. Through this structural design, the column head 320 can achieve a stable engagement between the protrusion 321 and the snap-fit ​​groove 322 when inserted, thereby improving the connection firmness of the fastener 300.

[0027] In this embodiment, the column head 320 has a symmetrical trumpet or hourglass shape, and its outer edge forms a guide surface, which can guide the protrusion 321 and the groove 322 to automatically align during the assembly process, making the insertion process smooth and improving the assembly efficiency.

[0028] In this embodiment, the connecting plate 310 is a sheet structure, and the column head 320 is fixed to the surface of the connecting plate 310 by integral injection molding. The surface of the connecting plate 310 is provided with mounting holes or adhesive layer structure, which are used to position and fix the fastener 300 between the protective frame 100 and the surface of the air conditioning unit, ensuring the stable installation of the fastener 300.

[0029] In this embodiment, the number of column heads 320 is no less than four rows, and they are evenly distributed along the longitudinal and transverse directions. This arrangement ensures that the protective frame 100 is evenly stressed on the surface of the air conditioning unit, preventing local loosening and improving the overall fixation reliability.

[0030] In this embodiment, an interference fit gap is provided between the protrusion 321 and the latching groove 322, so that after the insertion is completed, the protrusion 321 can form a friction lock with the latching groove 322, thereby effectively preventing the protective frame 100 from loosening due to vibration during the operation of the air conditioning unit.

[0031] In this embodiment, the post head 320 is made of elastic plastic. Because elastic materials have a certain deformation capacity, the post head 320 can undergo slight deformation between the protrusion 321 and the groove 322 during the insertion process, making insertion and removal smoother, avoiding damage to components, and improving the durability of the fastener 300.

[0032] Working principle During use, the protective frame 100 is installed on the surface of the air inlet of the air conditioning unit, and the non-woven filter layer 200 covers the protective frame 100. When outside air enters the air conditioning unit, it is first filtered by the non-woven filter layer 200, thereby effectively blocking dust and impurities and ensuring the cleanliness of the air delivered into the air conditioning unit.

[0033] The fastener 300 enables the quick assembly and disassembly of the protective frame 100 through the combination structure of the connecting plate 310 and the column head 320. When the protective frame 100 is positioned opposite the fastener 300 on the surface of the air conditioning unit, several columns 320 of the two fasteners 300 are interlocked, and the protrusion 321 and the fastening groove 322 form a snap-fit ​​engagement. During the interlocking process, the outer edge guide surface of the column head 320 plays an alignment role, ensuring that the protrusion 321 and the fastening groove 322 are smoothly engaged. After the interlocking is completed, the interference fit clearance between the protrusion 321 and the fastening groove 322 provides friction locking, so that the protective frame 100 is firmly installed on the surface of the air conditioning unit.

[0034] When the nonwoven filter layer 200 needs to be replaced or cleaned, the operator only needs to disassemble the protective frame 100. By pulling out the post head 320 of the fastener 300, the engagement between the protrusion 321 and the fastener groove 322 can be released. Because the post head 320 is made of elastic plastic, it can produce moderate deformation during insertion and removal, making the disassembly process simple and quick, and avoiding damage to the protective frame 100 and the fastener 300.

[0035] Thus, the dustproof structure of this utility model achieves two effects: firstly, through the cooperation of the protective frame 100 and the non-woven filter layer 200, it effectively blocks dust from the air inlet and improves the air quality during the operation of the air conditioning unit; secondly, through the structural design of the connecting plate 310 and the column head 320 of the fastener 300, the protective frame 100 can be quickly assembled and disassembled, which has the advantages of simple structure, convenient operation, firm fixation and high durability.
