Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air handling component and an air purification filter. Background Technology

[0002] Activated carbon possesses a rich porous structure and a large specific surface area, enabling it to adsorb odor molecules onto its surface through physical adsorption. Therefore, activated carbon filters are a core deodorizing component in many air purifiers. When air passes through the purifier, odor molecules are adsorbed by the activated carbon filter, thus achieving air deodorization and purification. In related technologies, deodorizing components typically employ mesh-like and honeycomb-like activated carbon deodorizing structures. Mesh-like activated carbon deodorizing structures use a two-dimensional stacking method, resulting in greater thickness, higher air resistance, and higher space occupancy. In honeycomb-like activated carbon deodorizing structures, the contact point / surface between the activated carbon and the honeycomb is the inner wall surface of the honeycomb, and each honeycomb pore is sealed. This results in a small contact area and short contact time between the air and the activated carbon, leading to lower deodorization performance. Utility Model Content

[0037] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 An air handling assembly 100 according to an embodiment of the present invention is described.

[0038] like Figure 1 and Figure 2 As shown, the air handling assembly 100 according to an embodiment of the present invention includes a body 1.

[0039] Specifically, refer to Figure 2 The main body 1 has multiple interconnected receiving spaces 11 arranged along a direction perpendicular to the thickness of the main body 1, and the receiving spaces 11 are connected to the outside of the main body 1. The "outside" refers to the air environment outside the main body 1. In the description of this utility model, "multiple" means two or more.

[0040] For example, in Figure 5 and Figure 6 In the example, the accommodating space 11 can be configured as a hollow circular or polygonal structure, etc. However, it is not limited to this. Multiple hollow accommodating spaces 11 are arranged along the first direction of the body 1 (i.e., Figure 1 The direction indicated by the middle arrow B) and the second direction (i.e. Figure 1The components are arranged closely together (in the direction indicated by the middle arrow C). That is, the body 1 is a three-dimensional mesh structure forming multiple accommodating spaces 11, which are arranged along the length direction (i.e., the first direction), width direction (i.e., the second direction), and / or width direction of the body 1. Figure 1 Other directions within the plane shown.

[0041] Thus, the body 1 forms a three-dimensional structure. The arrangement of the multiple accommodating spaces 11 on the body 1 allows the airflow to pass through the body 1 more evenly and smoothly, increasing the contact area and contact time between the airflow and the air treatment material 3. This improves the adsorption efficiency of the air treatment material 3 for odor gases in the airflow and enhances the deodorization effect. (In this embodiment, the air treatment material 3 is activated carbon granules, which are described in detail below.)

[0042] Furthermore, the arrangement of multiple receiving spaces 11 helps optimize the dispersion and flow of gas within the body 1, reducing gas short-circuiting or situations where the gas flow rate is too fast or too slow in certain areas. This allows the airflow to pass through the receiving spaces 11 more smoothly, improving the overall stability and reliability of the body 1. In addition, it improves the internal space utilization of the body 1, facilitating airflow along the thickness of the body 1. The overall structure of the body 1 is also lighter, which is beneficial for the installation (e.g., winding or bending) and use of the body 1, thus improving its usability.

[0043] Specifically, in combination Figure 1 and Figure 4 The body 1 includes a first body layer 12, a second body layer 13, a plurality of connecting segments 14, and an air treatment material component 3. Specifically, a plurality of first through holes 1211 are formed on the first body layer 12. The second body layer 13 is opposite to the first body layer 12, and a plurality of second through holes 1311 are formed on the second body layer 13. The connecting segments 14 connect the first body layer 13 and the second body layer 13, and the first body layer 12, the second body layer 13, and the plurality of connecting segments 14 together define a plurality of receiving spaces 11.

[0044] For example, refer to Figure 4 The first body layer 12 and the second body layer 13 are along the thickness direction of the air handling assembly 100 (i.e., Figure 2The first body layer 12 (as indicated by the middle arrow A) is arranged at intervals. The second body layer 13 is located directly below the first body layer 12, thereby ensuring sufficient airflow between the first body layer 12 and the second body layer 13 and contact with the air treatment material 3. Furthermore, the centers of the first body layer 12 and the second body layer 13 are aligned. That is, when viewed from directly above or below the thickness direction of the air treatment assembly 100, the outlines of the first body layer 12 and the second body layer 13 are essentially overlapping, ensuring that odorous gases can pass evenly through the treatment areas of the upper and lower layers, avoiding localized poor treatment effects and improving the space utilization of the air treatment assembly 100. In addition, the arrangement of the first body layer 12 and the second body layer 13 makes the structure of the air treatment assembly 100 more regular, thereby reducing its manufacturing and installation difficulties.

[0045] Furthermore, a plurality of first through holes 1211 are formed on the first body layer 12, and a plurality of second through holes 1311 are formed on the second body layer 13. That is, both the first body layer 12 and the second body layer 13 have a plurality of closely arranged through holes, with the first through holes 1211 and the second through holes 1311 penetrating through both the first body layer 12 and the second body layer 13. Thus, the closely arranged first through holes 1211 and second through holes 1311 create multiple gas flow channels inside the air handling assembly 100, effectively improving the air permeability of the first body layer 12 and the second body layer 13, thereby better improving the air permeability of the air handling assembly 100 and enhancing the deodorization effect.

[0046] Combination Figure 4 A plurality of connecting segments 14 are provided between the first body layer 12 and the second body layer 13. These connecting segments 14, opposite to each receiving space 11, are arranged circumferentially at intervals along the first through-hole 1211. For example, the connecting segments 14 may be vertical strips. The connecting segments 14 are adapted to connect the first body layer 12 and the second body layer 13 along the height direction of the air handling assembly 100, and both ends of each connecting segment 14 are connected to the sidewalls of the first through-hole 1211 and the second through-hole 1311, respectively. Thus, the plurality of connecting segments 14 tightly connect the first body layer 12 and the second body layer 13, forming a three-dimensional sandwich structure with high structural strength, thereby effectively enhancing the structural stability of the body 1. Furthermore, the aforementioned three-dimensional structure can increase the receiving space 11 of the air handling material 3, thereby effectively increasing the contact area and contact time between the airflow and the air handling material 3, and improving the deodorization efficiency of the air handling assembly 100. It should be noted that the shape of the plurality of connecting segments 14 can be set according to actual conditions, such as the designer's trade-offs and adjustments regarding airflow and filtration effect. For example, the shapes of the multiple connecting segments 14 can be straight lines, curves, arcs, irregular lines, etc., but are not limited to these. In this application, the connecting segments 14 are designed as straight lines to facilitate airflow and achieve higher airflow (i.e., reduce air obstruction).

[0047] Optionally, the positional relationship between the plurality of connecting segments 14 and the first body layer 12 and the second body layer 13 can be as follows: First, the plurality of connecting segments 14 can be along the thickness direction of the air handling assembly 100 (i.e., Figure 2 The direction indicated by the middle arrow A) is perpendicular to the first body layer 12 and the second body layer 13 (as shown by the middle arrow A). Figure 2 (As shown in the diagram). This arrangement facilitates airflow, achieving a higher airflow rate (i.e., reducing air obstruction). Second, the multiple connecting segments 14 may not be perpendicular to the first body layer 12 and the second body layer 13; that is, the connecting segments 14 form an angle with the plane containing the first body layer 12 and the second body layer 13. This arrangement facilitates air treatment (e.g., deodorization) effects, increasing the time air remains within the body 1 and enhancing the contact time with the air treatment material 3, thereby improving the air treatment effect.

[0048] Reference Figure 2 Air treatment material 3 is disposed within a plurality of receiving spaces 11, and at least a portion of the air treatment material 3 is attached to the connecting section 14. For example, in Figure 1 , Figure 2 and Figure 6 In the example, the air treatment material 3 can be disposed on the side wall of the accommodating space 11. Therefore, when air flows into the body 1, the contact area and contact time between the air treatment material 3 and the air can be effectively increased, thereby improving its adsorption efficiency for odor gases. Furthermore, the space within the air treatment assembly 100 can be fully utilized to increase the filling amount of the air treatment material 3. Thus, without increasing the volume of the air treatment assembly 100, as much air treatment material 3 as possible can be filled within a limited space, increasing the total gas adsorption capacity and thereby improving the performance of the air treatment assembly 100.

[0049] Optionally, the air treatment material component 3 is bonded to the connecting section 14. For example, adhesive can be sprayed onto the connecting section 14 to adhere the air treatment material component 3, thereby improving the space utilization rate inside the air treatment assembly 100. More air treatment material components 3 can be arranged within a limited space, increasing the loading capacity of the air treatment material components 3 and improving the deodorization capacity of the air treatment assembly 100. Furthermore, the adhesion of the air treatment material component 3 to the connecting section 14 creates more adsorption points in the gas flow channels, allowing the gas to fully contact the air treatment material component 3 as it flows through these areas, improving the adsorption efficiency of odor molecules and enhancing the overall deodorization effect of the air treatment assembly 100. Additionally, the aforementioned adhesion method of the air treatment material component 3 can, to a certain extent, increase the connection strength and stability between the two layers, thereby improving the overall structural strength of the air treatment assembly 100 and extending its service life.

[0050] According to the air handling assembly 100 of this utility model, multiple connecting segments 14, a first body layer 12, and a second body layer 13 together define multiple accommodating spaces 11, thereby forming a three-dimensional sandwich structure with high structural strength, which effectively enhances the structural stability of the body 1. Furthermore, the aforementioned three-dimensional sandwich structure can also increase the accommodating space 11 of the air handling material 3, thereby effectively increasing the contact area and contact time between the airflow and the air handling material 3, and improving the deodorization efficiency of the air handling assembly 100. In addition, the air handling assembly 100 has a regular structure, low manufacturing difficulty, low production cost, and a stable structure that is not easily deformed, making it suitable for large-scale production and application.

[0051] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The air handling assembly 100 further includes at least one protective layer 4, which is disposed on at least one side of the body 1 in the thickness direction. The protective layer 4 has a plurality of openings 41 formed thereon, and the exterior of the body 1 communicates with the receiving space 11 through the openings 41. The term "at least one" refers to the presence of at least one protective layer 4, but multiple layers are also possible. For example, in… Figure 1 and Figure 2 In the example, along the thickness direction of body 1 (i.e. Figure 2 A protective layer 4 is provided on the outer surface (in the direction indicated by the middle arrow A), and the protective layer 4 is stacked on top of the main body 1. The shape and surface area of ​​the protective layer 4 are adapted to the shape and thickness of the main body 1. Thus, the protective layer 4 can provide physical protection for the main body 1, preventing it from being damaged by external impacts or friction during installation and use, thereby ensuring the structural integrity and operational stability of the main body 1. In addition, the protective layer 4 can also prevent the air treatment material 3 inside the main body 1 from falling out, and block external impurities such as dust, particulate matter, and moisture from entering the deodorization structure, thereby extending the service life of the main body 1 and ensuring the stability of its deodorization performance.

[0052] Optionally, the protective layer 4 can be bonded to the outer surface of the body 1 using hot melt adhesive. After cooling and curing, the hot melt adhesive has strong bonding force, allowing the protective layer 4 to be firmly bonded to the upper and lower outer surfaces of the body 1. Therefore, the protective layer 4 is less likely to detach from the outer surface of the body 1, ensuring the structural stability of the air handling unit 100 and extending its service life. Furthermore, the hot melt adhesive has a wide temperature range, performing well in both high and low temperature environments, thus ensuring that the deodorization performance of the air handling unit 100 is unaffected by temperature changes.

[0053] Furthermore, the protective layer 4 has multiple openings 41, which can be arranged at equal or non-equal intervals along the length and / or width of the body 1. For example, the protective layer 4 can be a mesh structure. Thus, the receiving space 11 containing the air handling material 3 can communicate with the outside of the body 1 through the openings 41, ensuring unobstructed airflow. Gas can flow through the openings 41 to the surrounding area of ​​the air handling material 3, allowing the air handling material 3 to fully contact the gas and quickly exert its adsorption effect, improving the deodorization efficiency of the air handling assembly 100. In addition, the interconnected structure allows for pressure and humidity balance inside and outside the air handling assembly 100, which helps maintain the optimal adsorption state of the air handling assembly 100, thereby ensuring the working performance and stability of the air handling assembly 100 and extending its service life.

[0054] According to some embodiments of this utility model, there are multiple protective layers 4, which are respectively disposed on both sides of the body 1 in the thickness direction. For example, the body 1 is provided with two protective layers 4, which are respectively located on the outer surfaces of the upper and lower sides in the thickness direction of the air handling assembly 100, and are stacked in a multi-layer structure along the thickness direction of the body 1, with the protective layers 4, the body 1 and the protective layers 4 stacked together.

[0055] Therefore, by providing a protective layer 4 on each of the upper and lower outer surfaces of the air handling assembly 100, the air handling material component 3 that falls off during use can be confined inside the air handling assembly 100, preventing its loss and thus ensuring the deodorization efficiency of the air handling assembly 100. Furthermore, it prevents the falling air handling material component 3 from affecting the operation of other components in the air purification filter, effectively improving the performance of the air purification filter and enhancing the user experience. In addition, the protective layer 4 can also guide the airflow, allowing the gas flowing into the body 1 to be more evenly dispersed into multiple receiving spaces 11, facilitating full contact between the gas to be purified and the air handling material component 3, thereby improving the deodorization efficiency of the body 1. Moreover, providing the protective layer 4 on the outer surface of the body 1 increases its structural strength, preventing damage or deformation due to external forces, ensuring its performance, and extending its service life.

[0056] According to some embodiments of this utility model, refer to Figure 1The maximum length of the opening 41 is less than the maximum length of the air handling material component 3. This arrangement creates an internal and external communication structure where the opening 41 corresponds to the receiving space 11. Because the maximum length of the opening 41 is less than the maximum length of the air handling material component 3, the protective layer 4 can confine the air handling material component 3 inside the air handling assembly 100, preventing it from detaching from the opening 41 and affecting the deodorization efficiency of the air handling assembly 100. This also facilitates the long-term stable use of the air handling assembly 100. Furthermore, the protective layer 4 can effectively block dust, particulate matter, and other impurities from entering the air handling assembly 100, ensuring that its deodorization effect is not affected. In addition, the protective layer 4 can also rectify the airflow entering the air handling assembly 100. When the maximum length of the opening 41 is less than the maximum length of the air handling material component 3, the protective layer 4 can disperse the airflow to a certain extent, preventing the airflow from concentrating in certain local areas, thereby improving the utilization rate of the deodorizing material and making the deodorization effect of the entire air handling assembly 100 more uniform and stable.

[0057] According to some embodiments of this utility model, refer to Figure 1 The cross-sectional area of ​​the first through hole 1211 is greater than the cross-sectional area of ​​the opening 41; and / or, the cross-sectional area of ​​the second through hole 1311 is greater than the cross-sectional area of ​​the opening 41.

[0058] For example, the cross-sectional areas of the first through-hole 1211 and the second through-hole 1311 can be configured in the following ways: First, only the cross-sectional area of ​​the first through-hole 1211 is larger than the cross-sectional area of ​​the opening 41 on the upper protective layer 4 in the thickness direction of the air handling assembly 100; second, only the cross-sectional area of ​​the second through-hole 1311 is larger than the cross-sectional area of ​​the opening 41 on the lower protective layer 4 in the thickness direction of the air handling assembly 100; third, the cross-sectional area of ​​the first through-hole 1211 is larger than the cross-sectional area of ​​the opening 41 on the upper protective layer 4 in the thickness direction of the air handling assembly 100. Simultaneously, the cross-sectional area of ​​the second through-hole 1311 is larger than the cross-sectional area of ​​the opening 41 on the lower protective layer 4 in the thickness direction of the air handling assembly 100.

[0059] This configuration allows the larger apertures of the first through-hole 1211 and the second through-hole 1311 to provide a larger accommodating space 11 for the air treatment material component 3, facilitating its filling and fixation and ensuring more uniform distribution within the structure, thereby enhancing its deodorization effect. The smaller apertures of the protective layer 4 confine the air treatment material component 3 within the air treatment assembly 100, preventing it from falling out due to vibration, airflow, or other factors. Furthermore, this aperture design contributes to enhancing the stability and structural strength of the entire air treatment assembly 100. The smaller apertures of the protective layer 4 provide a tighter support structure, resisting external pressure and impact, and protecting the air treatment assembly 100 from damage. Additionally, it helps optimize airflow within and outside the air treatment assembly 100, reducing airflow resistance and allowing for smoother gas flow within the assembly.

[0060] According to some embodiments of this utility model, combined with Figure 5 The air handling assembly 100 also includes a support 2, which surrounds the outer periphery of the body 1.

[0061] Combination Figure 5 The support portion 2 surrounds the outer periphery of the main body 1. For example, in Figure 1 and Figure 5 In the example, the support portion 2 extends circumferentially along the periphery of the body 1. The perimeter of the support portion 2 is approximately the same as the perimeter of the body 1, and its height is also approximately the same as the overall height of the body 1. Thus, the support portion 2 can completely enclose the body 1 within itself. Therefore, the peripheral support portion 2 can provide stable support for the body 1, ensuring that it maintains its shape and structural integrity under various usage conditions, preventing structural deformation or collapse of the body 1 due to external pressure, thereby guaranteeing the normal operation of its deodorization function. Furthermore, the support portion 2 can also protect the internal air treatment material component 3 and other functional layers from damage by external factors. For example, it prevents dust, moisture, impurities, etc., from entering the interior, avoiding the effects of these substances on the air treatment material component 3, such as pollution, clogging pores, or reducing its adsorption performance, thus extending the service life of the body 1.

[0062] Furthermore, the peripheral support portion 2 typically has a specific shape and structure to facilitate the installation and fixation of the air handling assembly 100 within the air purification filter or other equipment. This specific shape and structure allows the air handling assembly 100 to cooperate well with other components of the air purification filter, ensuring accurate and stable installation of the air handling assembly 100 within the air purification filter. This makes the overall assembly and maintenance of the air purification filter more convenient, and also promotes the integration and miniaturization of the air purification filter, enhancing its market competitiveness. It should be noted that the shape of the support portion 2 is adapted to the shape of the body 1. The shape and size of the support portion 2 can be set according to specific circumstances and are not specifically limited here. In this embodiment, the support portion 2 is planar and perpendicular to the surfaces where the first body layer 12 and the second body layer 13 are located. In this way, the internal space of the body 1 can be sealed in a relatively simple manner, and the overall space occupied by the body 1 can be reduced, preventing the air handling material component 3 from falling out and avoiding affecting the user's experience.

[0063] Optionally, the support 2 is bonded to the outer peripheral surface of the body 1. For example, the support 2 is fixed to the outer peripheral side of the body 1 by hot melt adhesive. On the one hand, hot melt adhesive has strong adhesion, which can tightly connect the support 2 and the body 1 in a short time, achieving a good bonding effect. This makes the support 2 less likely to loosen or fall off, extending the service life of the body 1 and ensuring the structural stability and normal operation of the air purification filter. Moreover, hot melt adhesive can cool and solidify quickly, effectively improving the production efficiency of the body 1 and thus reducing the production cost of the air handling unit 100. On the other hand, hot melt adhesive has a certain structural strength after cooling, making the body 1 more stable and improving its structural strength, so that the body 1 maintains its shape and position stability during long-term use.

[0064] According to some embodiments of the present invention, the support part 2 includes non-woven fabric, sponge, foamed paper or plastic parts.

[0065] For example, non-woven fabric components possess a certain strength and toughness. When used as support parts 2 on the outer periphery of the main body 1, they can form a stable support frame around the main body 1, preventing deformation and collapse due to external forces or internal pressure, thus ensuring the integrity and stability of the main body 1. Furthermore, the good flexibility of non-woven fabric allows the support parts 2 to provide cushioning and shock absorption. When the main body 1 is subjected to external impact or vibration, the support parts 2 can disperse some of the impact force, reducing damage to the interior of the main body 1 and protecting the stability and reliability of the entire air treatment assembly 100. In addition, the porous structure of non-woven fabric facilitates gas diffusion within the main body 1, allowing the gas to fully contact the air treatment material components 3, thereby improving the deodorization efficiency of the air treatment assembly 100. Moreover, the low production cost, light weight, and good processability of non-woven fabric components reduce the production cost of the main body 1, facilitate production and transportation, and effectively enhance the market competitiveness of the air treatment assembly 100.

[0066] Paper is a relatively inexpensive material with wide availability and mature manufacturing processes. Using it in the support portion 2 of the main body 1 can effectively reduce the production cost of the air handling assembly 100 and enhance its market competitiveness. Furthermore, paper has a low density and is lightweight, which is beneficial for the lightweight development of the air handling assembly 100, thereby reducing the weight of the air purification filter. In addition, paper has a certain degree of air permeability, which facilitates airflow within the main body 1, allowing for smoother airflow within the air handling assembly 100, thereby improving the deodorization efficiency of the air handling assembly 100.

[0067] Sponge is a soft and elastic material. When used as the support part 2 on the outer periphery of the main body 1, the support part 2 can adapt well to the shape and structure of the main body 1, allowing it to fit tightly against the outer periphery of the main body 1, thus providing stable support. Furthermore, when the main body 1 is subjected to external impact, the support part 2 can act as a buffer, protecting the internal structure and function of the main body 1 from damage, thereby extending the service life of the main body 1. In addition, sponge is relatively inexpensive, effectively reducing production costs and improving market competitiveness while ensuring the performance of the air treatment component 100.

[0068] The foam component possesses a certain degree of hardness and strength. When the sponge is used as the support part 2 on the outer periphery of the main body 1, it can provide reliable support for the main body 1, ensuring that it maintains a stable shape and structure during use and is not easily deformed or damaged. Furthermore, the foam component is lightweight, which is beneficial to the lightweight development of the air handling assembly 100, effectively reducing its transportation and installation difficulties, thereby improving the production efficiency of the air purification filter. In addition, the foam component has good waterproof performance, preventing moisture from penetrating the interior of the main body 1 and avoiding problems such as failure of the air handling material component 3 due to moisture. It also helps to keep the environment around the main body 1 dry, reducing the possibility of bacterial and mold growth.

[0069] Plastic parts can be manufactured into support sections 2 of various shapes and sizes through various molding processes, such as injection molding and extrusion, precisely meeting the design requirements of the air handling unit 100 and adapting to different application scenarios and spatial layouts. Moreover, plastic parts are lightweight, facilitating installation and handling, which is beneficial for the lightweight development of the air handling unit 100, thereby reducing the weight of the air purification filter. Furthermore, plastic parts possess strong chemical stability and insulation properties, which helps ensure the structural integrity and stability of the support section 2, extending the service life of the main body 1 and improving its safety. In addition, the lower raw material and processing costs of plastic parts can effectively reduce production costs while ensuring the deodorization effect of the air handling unit 100, thus enhancing the product's market competitiveness.

[0070] For example, the support portion 2 can be made of polyethylene terephthalate (PET), which provides reliable support while being relatively lightweight. Furthermore, PET is an electrical insulator; when the air handling assembly 100 is used in a large air purifier, it avoids safety hazards caused by the conductivity of the support portion 2, thus improving the overall safety of the air purifier. In addition, the production and processing technology of PET components is relatively mature; using PET components as the support portion 2 can effectively reduce production costs while meeting performance requirements, thereby enhancing the market competitiveness of the air handling assembly 100.

[0071] According to some preferred embodiments of the present invention, the support portion 2 is planar and perpendicular to the surface where the first body layer 12 and / or the second body layer 13 are located.

[0072] For example, in this application, the support portion 2 is planar and perpendicular to the surfaces containing the first body layer 12 and the second body layer 13. This arrangement allows for the sealing of the internal space of the body 1 in a relatively simple manner and reduces the overall space occupied by the body 1. Furthermore, it prevents the air handling material 3 from falling out, thus avoiding any impact on the user's experience.

[0073] According to some embodiments of this utility model, refer to Figures 3-6Multiple first through holes 1211 constitute multiple first through hole groups 121, and the multiple first through hole groups 121 are along a first direction (i.e. Figure 3 The multiple first through holes 1211 of each first through hole group 121 are arranged along the second direction (i.e., the direction indicated by the middle arrow B). Figure 3 Arranged in the direction indicated by the middle arrow C). The second body layer 13 and the first body layer 12 are arranged along a third direction (i.e., ...). Figure 4 Arranged at intervals in the direction indicated by the middle arrow A, a plurality of second through holes 1311 are formed on the second body layer 13. The second through holes 1311 communicate with the opening 41. The plurality of second through holes 1311 constitute a plurality of second through hole groups 131. The plurality of second through hole groups 131 are arranged along a first direction. The plurality of second through holes 1311 in each second through hole group 131 are arranged along a second direction. The first direction, the second direction, and the third direction are orthogonal. For example, in Figure 3 In the example, a plurality of first through holes 1211 are formed on the first body layer 12. These first through holes 1211 form a group 121 of first through holes arranged closely along a first direction. Within each group 121, the first through holes 1211 are arranged closely along a second direction, i.e., in an array. This arrangement allows the closely arranged first through holes 1211 to effectively increase the contact area between the air handling material 3 and the gas, enabling more gas to fully contact the air handling material 3 through the first through holes 1211, thereby improving the deodorization efficiency of the air handling assembly 100. Furthermore, in the above arrangement, the first body layer 12 has a larger number of first through holes 1211, resulting in a higher total area ratio and higher air permeability, thus better improving the air permeability of the air handling assembly 100 and enhancing the deodorization effect. Similarly, the arrangement and position of the second through hole 1311 and the second through hole group 131 on the second body layer 13 are largely the same as those of the first through hole 1211 and the first through hole group 121 on the first body layer 12. This reduces the installation difficulty of the air handling assembly 100 and lowers the error rate. It should be noted that the first direction, the second direction, and the third direction are perpendicular to each other, and the first body layer 12, the second body layer 13, and the connecting section 14 together constitute the three-dimensional mesh structure of the body 1.

[0074] According to some optional embodiments of the present invention, the first through hole 1211 and the second through hole 1311 are provided correspondingly to each other, and the plurality of connecting segments 14 are perpendicular to the plane where the first body layer 12 and the second body layer 13 are located. That is, the plurality of first through holes 1211 and second through holes 1311 are in the thickness direction of the air treatment assembly 100 (i.e., Figure 2The components (in the direction indicated by arrow A) correspond one-to-one, thus forming a highly interconnected body 1 structure. This arrangement effectively shortens the airflow path within the air handling unit 100, improving gas exchange efficiency and consequently enhancing the deodorization efficiency of the air handling unit 100. Furthermore, the multiple connecting segments 14 are perpendicular to the plane containing the first body layer 12 and the second body layer 13, which improves the structural strength of the body 1 and prevents deformation or bending of the body 1 due to external forces during use, thereby extending the service life of the body 1.

[0075] According to some preferred embodiments of the present invention, refer to Figure 1 The first through hole 1211 and the second through hole 1311 are staggered, and the multiple connecting segments 14 form an angle with the plane containing the first body layer 12 and the second body layer 13. That is, the first through hole 1211 and the second through hole 1311 are in a third direction (i.e., Figure 4 The connecting segments 14 are arranged in an alternating pattern along the direction indicated by the middle arrow A, and are tilted, forming an angle with the plane containing the first body layer 12 and the second body layer 13. It should be noted that the angle formed by the connecting segments 14 with the plane containing the first body layer 12 and the second body layer 13 can be set according to the actual situation, and is not specifically limited here.

[0076] This arrangement ensures a reasonable distribution of the first through-hole 1211 on the first body layer 12 and the second through-hole 1311 on the second body layer 13 along the thickness direction of the air handling assembly 100. When airflow passes through the air handling assembly 100, the flow path is minimized, reducing gas resistance within the through-holes and improving gas exchange efficiency, thereby enhancing the deodorization efficiency of the air handling assembly 100. Furthermore, it allows air to change its flow direction as it passes through the first body layer 12 and the second body layer 13, increasing gas turbulence and allowing for more thorough contact with the air handling material 3, thus improving deodorization efficiency, ventilation efficiency, and heat dissipation performance. Additionally, it enhances the strength and stability of the air handling assembly 100 while reducing weight. It should be noted that the arrangement of the through-holes on the first body layer 12 and the second body layer 13 can be customized to better meet practical applications and is not limited to the above arrangement. For example, the through-holes on the first body layer 12 and the second body layer 13 can also be partially staggered, randomly distributed, or aligned. However, it is not limited to these arrangements.

[0077] According to some embodiments of the present invention, the first body layer 12, the second body layer 13 and the connecting segment 14 respectively include natural fiber parts, metal fiber parts or synthetic fiber parts.

[0078] For example, fibrous components are fibrous materials with a long, thin strip shape, typically made from natural or synthetic polymer compounds. On one hand, fibrous components are soft and flexible. When used as the first body layer 12, the second body layer 13, and the connecting section 14 of the air handling assembly 100, they can adapt to minor deformations and movements that may occur in the air handling assembly 100, ensuring the stability of the air handling assembly 100 and reducing damage to the overall structure of the air handling assembly 100 caused by minor deformations and movements, thereby improving the stability of the air handling assembly 100 and extending its service life. Furthermore, fibrous components have a certain porosity, which facilitates gas flow, allowing gas to diffuse smoothly within the air handling assembly 100, thus enabling it to fully contact the deodorizing structural components and improving the deodorization efficiency of the air handling assembly 100. In addition, fibrous components have good chemical stability and are not easily chemically reacted with substances in the gas, ensuring their long-term stability and extending the service life of the air handling assembly 100. In addition, the relatively low cost of fiber components can effectively reduce production costs and enhance the market competitiveness of the air handling unit 100 while ensuring its structural strength. Moreover, the lightweight nature of the fiber filaments allows for effective control of the overall weight of the air handling unit 100, facilitating installation and transportation.

[0079] For example, natural fiber components have a porous structure and a large specific surface area, giving them a certain adsorption capacity. When natural fiber components are used to manufacture the first body layer 12, the second body layer 13, and the connecting section 14 of the air handling assembly 100, their internal micropores can adsorb odor molecules in the air, thus achieving deodorization. Furthermore, the surface of natural fiber components may contain polar groups that can interact physically or chemically with odor molecules, enhancing the adsorption effect. In addition, natural fiber components have good air permeability, allowing air to circulate freely. In the air handling assembly 100, this helps improve deodorization efficiency and also prevents stuffiness and humidity inside the air handling assembly 100 due to poor air circulation, reducing bacterial growth and further lowering the possibility of odor generation. Moreover, natural fiber components have good processing properties and can be manufactured into different shapes and structures of the first body layer 12, the second body layer 13, and the connecting section 14 through various processing methods to adapt to different application scenarios. For example, natural fiber components can be plant fiber components, animal fiber components, mineral fiber components, etc., which can be selected according to actual needs to meet specific application requirements.

[0080] Metal fiber components possess high strength and rigidity, enabling them to withstand significant pressure and tension without easily deforming. In the air handling unit 100, this ensures stability during installation and use, maintaining its shape and performance even under long-term use and harsh environmental conditions, guaranteeing the durability of its deodorization effect. Furthermore, metal fiber components, through special treatment or inherent corrosion resistance (e.g., stainless steel fibers), resist the erosion from acids, alkalis, and humid environments encountered during deodorization, thus maintaining stable performance and reducing the maintenance and replacement costs of the air handling unit 100.

[0081] Synthetic fiber components possess numerous microporous structures on their surface and interior, resulting in a large specific surface area. This allows them to adsorb odor molecules from the air, thereby achieving deodorization. When synthetic fiber components are used to manufacture the first body layer 12, the second body layer 13, and the connecting section 14 in the air handling assembly 100, the deodorization efficiency of the air handling assembly 100 can be further improved. Furthermore, synthetic fibers possess high strength, wear resistance, and tensile strength, enabling the first body layer 12, the second body layer 13, and the connecting section 14 to withstand certain pressure and friction without easily deforming, breaking, or wearing down. This ensures that they maintain their shape and structural integrity during long-term use, guaranteeing the stability of the deodorization effect of the air handling assembly 100. Additionally, the production cost of synthetic fiber components is relatively low, which helps reduce the production cost of the air handling assembly 100, enhancing its market competitiveness and facilitating its widespread application in various fields, such as deodorization in homes, industries, and public places.

[0082] For example, the connecting section 14 can be woven from polyester filaments, thus forming a layered three-dimensional air treatment assembly 100. Polyester fibers possess high strength and abrasion resistance, and the connecting section 14 woven from polyester filaments can withstand greater tensile and frictional forces, making it less prone to breakage. This improves the structural strength of the air treatment assembly 100 and extends its service life. Furthermore, the layered three-dimensional air treatment assembly 100 has a spatially interlaced internal structure, which effectively reduces wind resistance during gas passage, thereby improving the deodorization efficiency of the air treatment assembly 100.

[0083] According to some optional embodiments of this utility model, the air treatment material component 3 can be activated carbon particles, diatomaceous earth, or zeolite, etc., but is not limited to these. With this configuration, the air treatment material component 3 has a strong adsorption capacity and chemical stability for odor gases, effectively improving the deodorization efficiency of the air treatment component 100 and extending its service life. Furthermore, the raw material cost of the air treatment material component 3 is low, making it suitable for large-scale use and enhancing the market competitiveness of the air treatment component 100. In other embodiments, the air treatment material component 3 can also be aromatic particles (for enhancing the air's fragrance effect), formaldehyde-removing particles (e.g., various substrates loaded with formaldehyde-removing formulations), silica particles (for dehumidification), etc., or a mixture of various materials. Since there are many materials with different functions, designers in the art can use them as needed, and will not elaborate further here.

[0084] The air treatment material component 3 is attached to the connecting section 14, for example, by using a carbon-coated spray method to fix it within the receiving space 11. First, activated carbon particles are evenly spread within the receiving space 11. Then, liquid binder is evenly sprayed onto the activated carbon particles using a spray gun. The binder penetrates into the gaps between the activated carbon particles, and after drying, forms an adhesive bond, fixing the activated carbon particles within the receiving space 11. Thus, fixing the air treatment material component 3 within the receiving space 11 by using a carbon-coated spray method ensures that the air treatment material component 3 is evenly distributed within the receiving space 11. When gas passes through the air treatment material component 3, the gas can contact the air treatment material component 3 evenly, improving the consistency of the air treatment assembly 100's adsorption effect on odor gases, thereby improving the performance of the air purification filter. Furthermore, the carbon-coated spray method allows for precise control of the amount of binder used and the spraying range, improving the production yield of the air treatment assembly 100, thereby reducing the production cost and difficulty of the air treatment assembly 100.

[0085] According to some preferred embodiments of the present invention, the air treatment material 3 is an activated carbon granule.

[0086] For example, activated carbon possesses a rich microporous structure and a large specific surface area, thus providing numerous adsorption sites. When activated carbon granules are used as air treatment material 3 in the air treatment assembly 100, the air treatment material 3 exhibits strong adsorption capacity, effectively removing odor molecules from the air and thereby improving air quality. Moreover, the adsorption of air pollutants by activated carbon granules is primarily a physical adsorption process, involving no chemical reactions and preventing secondary pollution. Furthermore, activated carbon granules can adsorb various types of pollutants, enabling the air treatment assembly 100 to function effectively in complex air environments, thus expanding its application scenarios. In addition, activated carbon granules have relatively low operating costs and high cost-effectiveness, which helps reduce the production cost of the air treatment assembly 100, thereby enhancing its market competitiveness. Figure 2 In the example, air treatment material component 3 is activated carbon granules, which can be used for deodorization.

[0087] According to some embodiments of this utility model, refer to Figure 1 and Figure 5 The maximum width of the accommodating space 11 is W, where W satisfies: 4mm≤W≤15mm.

[0088] For example, in Figure 5 and Figure 6 In the example, the accommodating space 11 can be configured as a closely arranged hollow cylindrical or hexahedral shape, thereby effectively increasing the accommodating capacity of the air handling material 3 without increasing the volume of the air handling assembly 100, and improving the deodorization efficiency of the air handling assembly 100.

[0089] When the maximum width W of the accommodating space 11 is greater than 15 mm, the width of the accommodating space 11 is too large. On the one hand, an excessively wide accommodating space 11 will reduce the structural strength of the air handling assembly 100, making it more prone to deformation and damage, thereby affecting the performance and service life of the air handling assembly 100. When the maximum width W of the accommodating space 11 is less than 4 mm, the width of the accommodating space 11 is too small, resulting in less space for the distribution of the air handling material components 3, which is also not conducive to the placement of the air handling material components 3. In addition, if the accommodating space 11 of the air handling material components 3 is small, the number of air handling material components 3 in the air handling assembly 100 will be too small, making the air handling assembly 100 only able to handle gases with smaller flow rates and lower concentrations, thus limiting the application range of the air handling assembly 100. Furthermore, the accommodating spaces 11 are closely arranged along the first and second directions of the air handling assembly 100 body 1. When the maximum width of the accommodating space 11 is small, the distribution density of the accommodating spaces 11 will increase accordingly, which will increase the production difficulty and production cost of the air handling assembly 100.

[0090] Therefore, by setting the maximum width W of the accommodating space 11 to satisfy 4mm≤W≤15mm, the maximum width of the accommodating space 11 is reasonably set, which can meet the accommodating space 11 required for the uniform distribution of air handling material components 3, thereby improving the deodorization efficiency of the air handling assembly 100 and extending the service life of the air handling material components 3. Moreover, it is also beneficial to set the deodorization structural components within the accommodating space 11, improving the assembly efficiency of the air handling assembly 100. In addition, a suitable accommodating space 11 can also ensure the structural strength of the air handling assembly 100, reduce its production cost, expand the application range of the air handling assembly 100, and facilitate the large-scale production and application of the air handling assembly 100.

[0091] According to some embodiments of this utility model, refer to Figure 2 The thickness of the body 1 is H2, where H2 satisfies: 5mm≤H2≤30mm.

[0092] When the thickness of the body 1, H2, is greater than 30mm, the thickness of the body 1 is excessive. On the one hand, excessive thickness of the body 1 increases the overall volume and weight of the air handling unit 100, making its application susceptible to space constraints. Moreover, when the air handling unit 100 is installed in an air purification filter or needs to be replaced, the operation becomes more difficult, requiring more manpower and time. On the other hand, excessive thickness of the body 1 prolongs the gas flow path and time, thereby reducing the deodorization efficiency of the air handling unit 100.

[0093] When the thickness of the body 1 (H2) is less than 5 mm, the thickness of the body 1 is too small. This means the space 11 for the air treatment material component 3 is small, and the contact area between the air treatment material component 3 and the gas is also reduced. For example, for air treatment material components 3 such as activated carbon particles, surface area is one of the key factors determining their adsorption capacity. When the thickness of the body 1 is too small, the adsorption area provided by the air treatment assembly 100 is limited, and the air treatment material component 3 cannot fully adsorb odor molecules, resulting in reduced deodorization efficiency. Moreover, due to the small filling amount of the air treatment material component 3, the consumption rate of the air treatment material component 3 per unit time will be faster when treating the same amount of odorous gas. For example, in an environment continuously treating an environment containing a certain concentration of odorous gas, the activated carbon in the thin air treatment assembly 100 may quickly reach adsorption saturation, requiring more frequent replacement or regeneration of the deodorizing medium, increasing usage costs and maintenance workload. Furthermore, the residence time of gas in the air treatment assembly 100 is related to the component thickness. A smaller thickness results in a faster gas flow rate and a shorter contact reaction time with the air treatment material component 3. For example, in some deodorizing processes that rely on chemical reactions, if the reaction time is too short, the reaction will be incomplete, failing to fully convert odorous substances into harmless substances, thus affecting the deodorizing effect. In addition, if the thickness of the air handling unit 100 is too small, its structural strength may be affected, especially when subjected to certain pressure or external forces, making it prone to deformation and damage, thus affecting the service life of the air handling unit 100.

[0094] Therefore, by setting the thickness H2 of the body to satisfy the condition: 5mm ≤ H2 ≤ 30mm, the thickness of the body 1 is reasonably set. On the one hand, the space 11 for accommodating the air treatment material component 3 is sufficient, allowing for the filling of an appropriate amount of air treatment material component 3 according to actual conditions. This improves the deodorization performance of the air treatment component 100 while controlling its production cost. Moreover, the appropriate thickness of the body 1 ensures sufficient contact area and contact time between odor molecules and the air treatment material component 3, improving the deodorization efficiency of the air treatment component 100. On the other hand, it also ensures the structural stability of the air treatment component 100, allowing it to maintain a stable shape and performance during long-term use. Furthermore, it reduces manufacturing and processing difficulties, lowers production and transportation costs, and facilitates installation.
