Description

Technical Field

[0001] This disclosure pertains to the field of power equipment technology, and specifically relates to an electrical cabinet. Background Technology

[0002] Electrical cabinets are typically made of steel and are used to house electronic components. They are widely used in various industries. Since electrical cabinets are usually placed outdoors, their interiors inevitably become damp, necessitating moisture-proofing and ventilation measures.

[0003] In related technologies, electrical cabinets include a housing and a ventilation mechanism. The housing houses electronic components. An air outlet is located on the outer wall of the housing. The ventilation mechanism is located inside the housing and connected to the inner wall of the housing. The ventilation mechanism is opposite to the air outlet. Air is blown through the air outlet by the ventilation mechanism to achieve air exchange between the inside and outside of the housing.

[0004] However, in the above structure, since the ventilation mechanism blows air directly into the air outlet during ventilation, debris inside the box will be carried into the ventilation mechanism by the airflow, causing damage to the ventilation mechanism and affecting ventilation. Summary of the Invention

[0005] This disclosure provides an electrical cabinet that can dissipate heat from different locations inside the cabinet to improve heat dissipation efficiency. The technical solution is as follows: This disclosure provides an electrical cabinet, which includes a housing, a ventilation assembly, and a filter assembly. The housing has an air outlet on its side wall. The filter assembly includes a support frame and multiple adsorption modules. The support frame is located inside the housing and connected to the inner wall of the housing. The support frame divides the interior of the housing into a first chamber and a second chamber. The first chamber is connected to the outside of the housing through the air outlet. The second chamber is used to house electronic components. The ventilation assembly is located inside the first chamber. The multiple adsorption modules are spaced apart on the support frame and rotatably connected to the support frame. The axis of rotation of the multiple adsorption modules intersects the air blowing direction of the ventilation assembly. The multiple adsorption modules are used to rotate while the ventilation assembly is ventilating.

[0006] In another implementation of this disclosure, the adsorption module includes a magnet, an adsorbent, and a protective component; the adsorbent is wrapped around the magnet, the protective component is wrapped around the adsorbent, and the protective component is rotatably connected to the support frame.

[0007] In another implementation of this disclosure, the protective component includes a protective block and a protective net; the protective block has an internal cavity, the adsorbent is located inside the cavity of the protective block, and the protective net is located outside the protective block and connected to the protective block.

[0008] In another implementation of this disclosure, the supporting frame includes a plurality of supporting rods and a supporting plate. The plurality of supporting rods are radially arranged around the ventilation component as the center. The first end of each of the plurality of supporting rods is connected to the ventilation component, and the second end of the supporting rod is connected to the inner wall of the housing. The supporting plate is connected to two adjacent supporting rods and to the ventilation component. The first chamber and the second chamber are located on opposite sides of the supporting plate. At least one of the supporting rods and the supporting plate has a plurality of filter holes. The filter holes communicate with the first chamber and the second chamber. The plurality of filter holes correspond one-to-one with the plurality of adsorption modules, and the adsorption module is rotatably located within the corresponding filter hole.

[0009] In another implementation of this disclosure, the enclosure includes a base, a lifting and adjusting assembly, and a main cabinet; the lifting and adjusting assembly is located inside and connected to the base, the bottom of the main cabinet is movably located on the base and connected to the lifting and adjusting assembly, and the main cabinet is configured to move along the air blowing direction of the ventilation assembly under the adjustment of the lifting and adjusting assembly; the accommodating cavity is located inside the main cabinet, and the air outlet is located at the top of the main cabinet.

[0010] In another implementation of this disclosure, the lifting and adjusting assembly includes a rotating rod, a first bevel gear, a second bevel gear, a threaded cylinder, and a support rod; the rotating rod is rotatably connected to the base, and the direction of the axis of the rotating rod is perpendicular to the blowing direction of the ventilation assembly; the first bevel gear is sleeved on the rotating rod, the second bevel gear meshes with the first bevel gear, the threaded cylinder is coaxially connected to the second bevel gear, the support rod is threaded into the threaded cylinder, the first end of the support rod is movably located on the base, and the second end of the support rod is connected to the bottom of the main cabinet.

[0011] In another implementation of this disclosure, the outer wall of the threaded cylinder has an annular groove, and the lifting adjustment assembly further includes a limiting ring and a limiting rod. The limiting ring is rotatably located in the annular groove, the first end of the limiting rod is connected to the outer wall of the limiting ring, and the second end of the limiting rod is connected to the inner wall of the base.

[0012] In another implementation of this disclosure, the main cabinet includes a cabinet body and a moisture-proof board. The bottom of the cabinet body is connected to the moisture-proof board, and the moisture-proof board is connected to the second end of the support rod. The moisture-proof board has multiple air inlet chambers, which are arranged at intervals.

[0013] In another implementation of this disclosure, the moisture-proof board further includes a water storage chamber, which is connected to the plurality of air inlet chambers and is located on the side of the plurality of air inlet chambers away from the air outlet.

[0014] In another implementation of this disclosure, the air intake chamber has a conical structure, with the large end of the air intake chamber facing the air exchange assembly and the small end of the air intake chamber facing the base.

[0015] The beneficial effects of the technical solutions provided in this disclosure are: The electrical cabinet provided in this embodiment, when in use, includes a filter assembly comprising a support frame and multiple adsorption modules. This allows the support frame to connect to the ventilation assembly and the housing, dividing the accommodating cavity into independent first and second chambers. Since each adsorption module is rotatably connected to the support frame, and these multiple adsorption modules rotate while the ventilation assembly is blowing air, they exchange gas between the first and second chambers. Thus, when the ventilation assembly is exchanging air, the adsorption modules can rotate relative to the support frame, allowing air exchange between the first and second chambers while simultaneously adsorbing impurities. This effectively prevents impurities from entering the interior of the ventilation assembly, thereby avoiding damage to the ventilation assembly.

[0016] In other words, the above structure ensures air exchange both inside and outside the chamber under the blowing of the ventilation components, while the filter components filter the air flowing inside the chamber to prevent debris from entering the ventilation components.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0021] This disclosure provides an electrical cabinet, such as... Figure 1 As shown, the electrical cabinet includes a housing 1, which has an air outlet 100.

[0022] Figure 2 yes Figure 1 A sectional view of the upper part. Combined with... Figure 2 The cabinet 1 has an internal accommodating cavity 10. The electrical cabinet also includes a ventilation assembly 2 and a filter assembly 3. The filter assembly 3 includes a support mesh frame 31 and multiple adsorption modules 32. The support mesh frame 31 is located inside the cabinet 1 and connected to the inner wall of the cabinet 1, dividing the interior of the cabinet 1 into a first chamber 101 and a second chamber 102. The first chamber 101 communicates with the outside of the cabinet 1 through an air outlet 100, and the second chamber 102 is used to accommodate electronic components.

[0023] The ventilation assembly 2 is located within the first chamber 101. Multiple adsorption modules 32 are spaced apart on the support frame 31 and are rotatably connected to the support frame 31. The axis of rotation of the multiple adsorption modules 32 is oriented in the direction of (…). Figure 2 (b) and the blowing direction of the ventilation component 2 ( Figure 2 The adsorption modules 32 intersect in the middle direction (a), and multiple adsorption modules 32 are used to rotate while the ventilation component 2 is ventilating.

[0024] When the electrical cabinet provided in this embodiment is in use, since the electrical cabinet includes a filter assembly 3, and the filter assembly 3 includes a support mesh frame 31 and multiple adsorption modules 32, the accommodating cavity 10 can be divided into an independent first chamber 101 and a second chamber 102 by the support mesh frame 31, while the adsorption modules 32 are connected inside the housing 1. Since each adsorption module 32 is rotatably connected to the support mesh frame 31, and multiple adsorption modules 32 are used to rotate while the ventilation assembly 2 is blowing air, when the ventilation assembly 2 is ventilating, the adsorption modules 32 can rotate relative to the support mesh frame 31, so that the first chamber 101 and the second chamber 102 can be ventilated, while adsorbing impurities. This effectively prevents impurities from entering the interior of the ventilation assembly 2, thereby avoiding damage to the ventilation assembly 2.

[0025] In other words, the above structure can ensure that the air inside and outside the box 1 can be exchanged under the action of the ventilation component 2, and at the same time, the air flowing inside the box 1 can be filtered by the filter component 3 to prevent debris from entering the ventilation component 2.

[0026] Optionally, the first chamber 101 and the second chamber 102 are arranged along the air blowing direction of the ventilation assembly 2. This facilitates the arrangement of the first chamber 101 and the second chamber 102, and also enables rapid air exchange between the first chamber 101 and the second chamber 102 during the process of air exchange between the ventilation assembly 2 and the outside air when it blows air towards the air outlet 100.

[0027] The airflow direction mentioned above refers to the direction in which the air exchange component 2 blows air towards the air outlet 100. (See also...) Figure 2 The direction 'a' in the middle.

[0028] See you again Figure 1 Optionally, the enclosure 1 includes a base 11 and a main cabinet 13. The receiving cavity 10 is located inside the main cabinet 13. The air outlet 100 is located at the top of the main cabinet 13.

[0029] Figure 3 for Figure 1 The lower part of the sectional view, combined with Figure 3 The housing 1 also includes a lifting and adjusting assembly 12, which is located within and connected to the base 11. The bottom of the main cabinet 13 is movably located within the base 11 and connected to the lifting and adjusting assembly 12. The main cabinet 13 is configured to move along the airflow direction of the ventilation assembly 2 under the adjustment of the lifting and adjusting assembly 12.

[0030] In the above implementation, the cabinet 1 is set as a base 11, a lifting and adjusting component 12 and a main cabinet 13. In this way, the height of the main cabinet 13 relative to the base 11 can be flexibly changed by the lifting and adjusting component 12, so that the distance between the main cabinet 13 and the ground can be well adjusted when it rains, thereby preventing moisture from entering the main cabinet 13 and solving the problem of poor moisture protection in the existing system.

[0031] See also Figure 3 Optionally, the lifting and adjusting assembly 12 includes a rotating rod 121, a first bevel gear 122, a second bevel gear 123, a threaded cylinder 124, and a second support rod 125. The rotating rod 121 is rotatably connected to the base 11, and the direction of the axis of the rotating rod 121 is perpendicular to the blowing direction of the ventilation assembly 2. The first bevel gear 122 is sleeved on the outside of the rotating rod 121, the second bevel gear 123 meshes with the first bevel gear 122, the threaded cylinder 124 is coaxially connected to the second bevel gear 123, the second support rod 125 is threaded into the threaded cylinder 124, the first end of the second support rod 125 is movably located on the base 11, and the second end of the second support rod 125 is connected to the bottom of the main cabinet 13.

[0032] In the above implementation, the lifting and adjusting assembly 12 includes a rotating rod 121, a first bevel gear 122, a second bevel gear 123, a threaded cylinder 124, and a second support rod 125. The rotating rod 121 can be manually rotated. Simultaneously, the rotating rod 121 drives the first bevel gear 122 to rotate, which in turn drives the second bevel gear 123 to rotate. The rotation of the second bevel gear 123, in turn, drives the threaded cylinder 124 to rotate, which in turn moves the second support rod 125, causing it to rise or fall. This movement of the second support rod 125 then moves the main cabinet 13, ultimately causing the main cabinet 13 to rise relative to the base 11, increasing the distance between the main cabinet 13 and the base 11, thus achieving initial moisture protection.

[0033] In other words, by controlling the rotation of the rotating rod 121 in the above structure, the main cabinet 13 can be easily raised and lowered relative to the base 11.

[0034] In addition, to improve the support strength of the second support rod 125 to the main cabinet 13, there are two second support rods 125. Correspondingly, there are also two first bevel gears 122, two second bevel gears 123, and two threaded cylinders 124. That is, two first bevel gears 122 are sleeved on the outside of the rotating rod 121 at intervals, each first bevel gear 122 is sleeved on the outside of the corresponding rotating rod 121, each second bevel gear 123 meshes with the corresponding first bevel gear 122, each threaded cylinder 124 is coaxially connected to the corresponding second bevel gear 123, each second support rod 125 is threaded into the corresponding threaded cylinder 124, the first end of each second support rod 125 is movably located on the base 11, and the second end of each second support rod 125 is connected to the bottom of the main cabinet 13.

[0035] See also Figure 3 The lifting adjustment assembly 12 also includes a limit ring 126 and a limit rod 127.

[0036] Figure 4 This is a schematic diagram of the structure of the threaded cylinder provided in the embodiments of this disclosure, combined with... Figure 4 Optionally, the outer wall of the threaded cylinder 124 has an annular groove 1240. The retaining ring 126 is rotatably located within the annular groove 1240.

[0037] Figure 5 This is a schematic diagram of the structure of the limiting ring and limiting rod provided in the embodiments of this disclosure, combined with... Figure 5 The first end of the limiting rod 127 is connected to the outer wall of the limiting ring 126, and the second end of the limiting rod 127 is connected to the inner wall of the base 11.

[0038] In the above implementation, by using the annular groove 1240 and the limiting ring 126 together, not only can the rotation process of the threaded cylinder 124 be made more stable, but the threaded cylinder 124 can also only rotate and cannot move.

[0039] Of course, correspondingly, there can be two limiting rings 126. Each limiting ring 126 is rotatably located in the annular groove 1240 of the corresponding threaded cylinder 124. The first end of each limiting rod 127 is connected to the corresponding limiting ring 126, and the second end of each limiting rod 127 is connected to the inner wall of the base 11.

[0040] To improve the limiting effect of the limiting rod 127, each limiting ring 126 can be connected to two limiting rods 127, with the two limiting rods 127 located on the same straight line and the limiting rods 127 located on opposite sides of the corresponding limiting ring 126.

[0041] See you again Figure 3 Optionally, to facilitate operation of the rotating rod 121, one end of the rotating rod 121 protrudes beyond the base 11. The lifting adjustment assembly 12 also includes a rotating handle 129, which is fixed to the end of the rotating rod 121 that protrudes beyond the base 11.

[0042] In the above implementation, one end of the rotating rod 121 protrudes beyond the base 11, which facilitates the control of the rotating rod 121 from outside the base 11. The rotating handle 129 is fixed to the rotating rod 121 for easy operation.

[0043] For example, to further facilitate the operation of the rotating rod 121, the rotating handle 129 is a plastic part, bonded to the rotating rod 121 with adhesive, and the rotating handle 129 is provided with multiple interlocking anti-slip grooves. This increases the friction between the rotating handle 129 and the user's hand, making it easier to rotate the rotating rod 121.

[0044] See also Figure 3 Optionally, a connecting plate 1210 is connected to the top of the second support rod 125, and the connecting plate 1210 is connected to the bottom of the main cabinet 13. Guide blocks 1211 are respectively provided on both sides of the connecting plate 1210 facing the side wall of the base 11. A guide groove 111 is provided on the side wall of the base 11, and the guide blocks 1211 are movably located within the guide groove 111. The extending direction of the guide groove 111 is the same as the axial direction of the second support rod 125.

[0045] In the above implementation, the addition of a connecting plate 1210 allows the movement of the connecting plate 1210 and the second support rod 125 to be limited by the cooperation of the guide block 1211 of the connecting plate 1210 and the corresponding guide groove 111, so that the main cabinet 13 can be raised and lowered stably relative to the base 11.

[0046] For example, the lifting adjustment assembly 12 further includes a plurality of support columns 128, which are spaced apart along the length of the rotating rod 121. The first end of each support column 128 is welded to the bottom of the base 11, and the second end of each support column 128 is rotatably connected to the rotating rod 121. In this way, the rotating rod 121 can be supported by the support columns 128 to ensure stable rotation of the rotating rod 121.

[0047] Figure 6 This is a schematic diagram of the structure of the support column provided in the embodiments of this disclosure, combined with... Figure 6 The support column 128 is a cylindrical structural component, and each support column 128 has a rotating hole 1281 at its top, into which a rotating rod 121 is rotatably inserted. This allows for a simple rotational connection between the support column 128 and the rotating rod 121.

[0048] Figure 7 This is a schematic diagram of the structure of the base provided in the embodiments of this disclosure, combined with... Figure 7 In this embodiment, the base 11 is a steel plate structure with a mounting groove 110 in the middle, and the mounting groove 110 is used to install the lifting adjustment assembly 12.

[0049] Figure 8 This is a schematic diagram of the internal structure of the cabinet provided in the embodiments of this disclosure, combined with... Figure 8 Optionally, the main cabinet 13 includes a cabinet body 131 and a moisture-proof board 132. The bottom of the cabinet body 131 is connected to the bottom surface of the moisture-proof board 132, and the top surface of the moisture-proof board 132 is connected to the connecting plate 1210.

[0050] Figure 9 This is a schematic diagram of the structure of the moisture-proof board provided in the embodiments of this disclosure, combined with... Figure 9 The moisture-proof board 132 has multiple air inlet chambers 1321, which are arranged at intervals.

[0051] In the above implementation, the main cabinet 13 is configured as a cabinet body 131 and a moisture-proof board 132. The cabinet body 131 can accommodate electronic components, while the moisture-proof board 132 can further prevent moisture from entering the main cabinet 13, thereby improving the main cabinet 13's ability to isolate moisture.

[0052] Furthermore, the moisture-proof board 132 has multiple air intake chambers 1321 arranged at intervals. This allows the main cabinet 13 to introduce moisture into the air intake chambers 1321 while isolating moisture, causing it to condense into water quickly, thus further improving the ability to isolate moisture.

[0053] Optionally, the air intake chamber 1321 is a conical cavity, with the large end of the air intake chamber 1321 facing the air exchange assembly 2 and the small end of the air intake chamber 1321 facing the base 11.

[0054] The above structure can improve the condensation effect of the air intake chamber 1321, so that the moisture entering the air intake chamber 1321 can be quickly condensed into water.

[0055] Optionally, the moisture-proof board 132 also has a water storage chamber 1322 inside, which is connected to multiple air inlet chambers 1321. The water storage chamber 1322 is located on the side of the multiple air inlet chambers 1321 away from the air outlet 100.

[0056] In the above implementation, the water storage chamber 1322 is used to collect and recycle the condensate formed in the air intake chamber 1321.

[0057] In this embodiment, to facilitate communication between the water storage chamber 1322 and each air intake chamber 1321, each water storage chamber 1322 is provided with a communication hole 1323 on the side facing the air intake chamber 1321. One end of the communication hole 1323 is connected to the corresponding air intake chamber 1321, and the other end of the communication hole 1323 is connected to the water storage chamber 1322.

[0058] See you again Figure 1 For example, the cabinet 131 includes an outer box 1311 and two doors 1312. The outer box 1311 has a cuboid structure, and each door 1312 is rotatably connected to one side wall of the outer box 1311. The outer box 1311 and the two doors 1312 form a second chamber 102. The cabinet 131 can be easily closed or opened by rotating the doors 1312.

[0059] For example, the door 1312 is provided with a plurality of viewing windows 1313 spaced apart.

[0060] In the above implementation, the electronic components inside the cabinet 131 can be observed through the perspective window 1313.

[0061] Optionally, the viewing window 1313 is detachably connected to the door 1312 by screws or the like. This allows for the replacement of a damaged or dirty viewing window 1313.

[0062] For example, the perspective window 1313 is a high-strength glass structure. This gives the perspective window 1313 high strength and prevents it from being easily damaged.

[0063] Optionally, the cabinet 131 also includes a plurality of mounting plates 1314, which are located within the second chamber 102 and connected to the inner wall of the outer casing 1311. The plurality of mounting plates 1314 are stacked along the moving direction of the main cabinet 13.

[0064] By arranging multiple parallel mounting plates 1314 inside the outer casing 1311, electronic components can be placed in an orderly manner, resulting in a neat arrangement of electronic components.

[0065] In this embodiment, the mounting plate 1314 is detachably fixed to the inner wall of the outer casing 1311 by screws or the like, which facilitates the flexible assembly and disassembly of the mounting plate 1314, and allows for flexible adjustment of the number of mounting plates 1314 according to the size and quantity of electronic components.

[0066] Of course, in order to ensure airflow between each mounting plate 1314, multiple heat dissipation holes are provided on the mounting plate 1314.

[0067] Optionally, the main cabinet 13 also includes a top cover 133, which covers the top of the cabinet body 131 and is connected to the top of the cabinet body 131. An air outlet 100 is located in the middle of the top cover 133. The ventilation assembly 2 is located inside the top cover 133 and is connected to the inner wall of the top cover 133.

[0068] In the above implementation, the top cover 133 is used to form a space with the cabinet 131 to install the ventilation component 2.

[0069] For example, the top cover 133 and the cabinet 131 are detachably connected by fasteners such as screws. This facilitates the assembly of the above structure.

[0070] Optionally, the main cabinet 13 also includes a dustproof screen 134, which is located on the side of the air outlet 100 away from the ventilation component 2 and is connected to the top cover 133.

[0071] In the above implementation, the arrangement of the dustproof mesh 134 can effectively prevent dust and debris from being blown into the main cabinet 13 with the airflow, thereby preventing debris from entering the main cabinet 13.

[0072] In this embodiment, the dustproof mesh 134 is a steel wire mesh structure, which is welded to the top cover 133. This increases the strength of the dustproof mesh 134 and extends its service life.

[0073] Of course, the structure of the above-mentioned box 1 is not limited to the above description. It can also be a single box without a separate top cover 133, and the air outlet 100 can be directly opened on the top of the corresponding box.

[0074] See you again Figure 2 The ventilation assembly 2 includes a fan 21 and a mounting bracket 22. The mounting bracket 22 is connected to the inner wall of the top cover 133. The fan 21 is located between the mounting bracket 22 and the air outlet 100, and is connected to the mounting bracket 22. The fan blades 211 of the fan 21 face the air outlet 100.

[0075] In the above implementation, the ventilation component 2 is configured with the above structure and can be connected to the top cover 133 via the fixing bracket 22 to provide an installation base for the fan 21. The fan 21 is used to blow air towards the air outlet 100, thus achieving air exchange between the inside and outside of the main cabinet 13.

[0076] Optionally, the mounting bracket 22 includes multiple mounting rods 221, with the first end of each mounting rod 221 connected to the outer wall of the fan 21 and the second end of each mounting rod 221 connected to the inner wall of the top cover 133.

[0077] In the above implementation, the fixing frame 22 is set as a multi-rod structure, so that the fan 21 can be fixed to the top cover 133 by fixing rod 221.

[0078] In the above connection, the fixing rod 221 is connected to the outer wall of the fan 21 and the inner wall of the top cover 133 by welding, which can improve the connection strength between them.

[0079] Figure 10 This is a schematic diagram of the adsorption module provided in the embodiments of this disclosure, combined with... Figure 10 The adsorption module 32 includes a magnet 321, an adsorbent 322, and a protective component 323. The adsorbent 322 is wrapped around the magnet 321, and the protective component 323 is wrapped around the adsorbent 322. The protective component 323 is rotatably connected to the support frame 31.

[0080] In the above implementation, the adsorption module 32 is configured with a magnet 321, an adsorbent 322, and a protective component 323. The magnet 321 can adsorb metal debris, while the adsorbent 322 can adsorb particulate dust and other impurities. The protective component 323 is used to wrap and protect the adsorbent 322.

[0081] Optionally, the protective component 323 includes a protective block 3231 and a protective net 3232. The protective block 3231 has a cavity inside, the adsorbent 322 is located inside the cavity of the protective block 3231, and the protective net 3232 is located outside the protective block 3231 and connected to the protective block 3231.

[0082] In the above implementation, the protective block 3231 is used to hold the adsorbent 322, while the protective net 3232 is used to connect to the outside of the protective block 3231 to perform preliminary filtration of the adsorbed impurities.

[0083] Optionally, adsorbent 322 can be activated carbon adsorbent, which can effectively adsorb a large number of particles and other impurities in the airflow.

[0084] Figure 11 This is a schematic diagram of the supporting space frame provided in the embodiments of this disclosure, combined with... Figure 11Optionally, the supporting frame 31 includes a plurality of first support rods 311 and a supporting plate 312. The plurality of first support rods 311 are radially arranged around the ventilation assembly 2, with the ventilation assembly 2 as the center. The first end of each first support rod 311 is connected to the ventilation assembly 2, and the second end of each first support rod 311 is connected to the inner wall of the housing 1. The supporting plate 312 is connected to two adjacent first support rods 311 and to the ventilation assembly 2. The first chamber 101 and the second chamber 102 are located on opposite sides of the supporting plate 312.

[0085] At least one of the first support rod 311 and the support plate 312 has a plurality of filter holes 3110. The filter holes 3110 connect the first chamber 101 and the second chamber 102. The plurality of filter holes 3110 correspond one-to-one with a plurality of adsorption modules 32, and the adsorption module 32 is rotatably located within the corresponding filter hole 3110.

[0086] In the above implementation, the support frame 31 is configured as multiple first support rods 311 and support plates 312. This allows the first support rods 311 to serve as the basic framework for arranging the support plates 312 inside the housing 1. Simultaneously, the filter holes 3110 provide an installation base for the adsorption module 32.

[0087] The radiation mentioned above refers to the arrangement of multiple first support rods 311 at even intervals around the ventilation component 2 in different directions on the outer periphery of the ventilation component 2. For example, when there are 3 first support rods 311, the angle between two adjacent first support rods 311 is 120°; when there are four first support rods 311, the angle between two adjacent first support rods 311 is 90°, and so on.

[0088] Of course, at least one of the first support rod 311 and the support plate 312 has multiple filter holes 3110, meaning the filter holes 3110 can be directly formed on the first support rod 311. In this case, multiple filter holes 3110 can be spaced apart along the length of each first support rod 311. Alternatively, multiple filter holes 3110 can be formed only on the support plate 312, with the multiple filter holes 3110 spaced apart along the circumference of the support plate 312. Filter holes 3110 can also be arranged on both the first support rod 311 and the support plate 312; this disclosure does not limit this.

[0089] In this embodiment, to facilitate the installation of the adsorption module 32 and ensure its adsorption efficiency, the support frame 31 can be simply a support plate structure, i.e., the first support rod 311 structure is omitted, and only the support plate 312 structure is retained. In this case, the support plate is an annular plate, with its inner annular wall connected to the outer wall of the ventilation assembly 2, and its outer annular wall connected to the inner wall of the housing 1. The first chamber 101 and the second chamber 102 are located on opposite sides of the annular plate. Multiple sets of filter holes are uniformly arranged along the radial direction of the support plate, each set including multiple filter holes arranged at intervals. The adsorption module 32 is arranged in a one-to-one correspondence with the filter holes 3110, and the adsorption module 32 is rotatably located within the corresponding filter hole 3110.

[0090] To increase the strength of the support plate, the support plate mentioned above can be a steel plate structural component.

[0091] Of course, the support frame 31 can also consist of multiple support rods and a support net, that is, the support plate can be replaced by a support net structure, with multiple mesh holes evenly distributed on the support net. In this case, the support rods are arranged radially around the ventilation component 2, with the ventilation component 2 as the center. The first end of each first support rod 311 is connected to the ventilation component 2, and the second end of the first support rod 311 is connected to the inner wall of the housing 1. The support net is laid on the support rods, and the first chamber 101 and the second chamber 102 are located on opposite sides of the support net, and the first chamber 101 and the second chamber 102 are connected through the mesh holes of the support net. The adsorption module 32 is connected inside the mesh holes. That is to say, in this case, the support net replaces the support plate 312, and there is no need to arrange filter holes 3110 on the first support rod 311.

[0092] Figure 12 for Figure 2 Enlarged view of point A in the middle, combined with Figure 12 In order to facilitate the installation of the adsorption module 32 in the filter hole 3110, the first support rod 311 is provided with two disc-shaped protrusions 3111 on the two opposite inner walls of the filter hole 3110, and the outer wall of the protective block 3231 is provided with a groove. The protrusions 3111 pass through the protective net 3232 and are rotatably located in the groove.

[0093] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
