[0002] In existing technologies, air filters used for deodorizing air generally have a multi-layered mesh structure with activated carbon pasted on each mesh layer to achieve deodorization. However, this multi-layered stacking method results in a large filter thickness. When air flows through the filter, the resistance is high and the airflow channel is easily disordered, which reduces the airflow efficiency of the filter and affects its filtration performance, thus failing to meet people's demand for efficient air purification.

[0024] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-2 The filter element 100 of the air purification device according to the first aspect of the present invention is described.

[0025] like Figure 1 and Figure 2 As shown, the filter element 100 of the air purification device according to the first aspect of the present invention includes: at least one carrier 10 and a frame 40.

[0026] Specifically, the carrier 10 includes a plurality of spoilers 11, the plurality of spoilers 11 being arranged along the thickness direction of the spoilers 11 (e.g., Figure 2 The spoilers 11 are arranged at intervals (vertically and vertically) in a wave-like shape. The crest of any spoiler 11 is opposite to the crest of its adjacent spoiler 11, and the trough of any spoiler 11 is opposite to the trough of its adjacent spoiler 11. Two adjacent spoilers 11 together define a flow channel 20, and air can flow in the same direction along multiple flow channels 20. The flow channel 20 is filled with at least one layer of adsorption material 30. A frame 40 is fitted around the outer periphery of the carrier 10.

[0027] For example, in Figure 2 In the example, the number of baffles 11 can be four, but is not limited to this. Each baffle 11 has a roughly identical structure. Along the thickness direction of the baffle 11, the crest of one baffle 11 is positioned opposite to the crest of another adjacent baffle 11, or the trough of one baffle 11 is positioned opposite to the trough of another adjacent baffle 11, so that the flow channel 20 between two adjacent baffles 11 has a uniform flow field. When the airflow passes through the flow channel 20, the wave-shaped baffles 11 can guide the airflow, allowing the air to flow in the same direction along multiple flow channels 20. Compared with the mesh layer in existing filter elements, this reduces turbulence caused by airflow collisions with the mesh layer. The wave-shaped baffles 11 have lower air resistance, improving airflow efficiency and thus ensuring the filtration performance of the filter element 100 of the air purification device. Furthermore, the wave-shaped structure increases the contact area between the adsorbent 30 and the airflow, allowing the adsorbent 30 to more fully adsorb impurities in the airflow, enhancing filtration performance and improving the air purification effect.

[0028] Moreover, compared with the mesh layer in the existing filter element, the shape of the baffle 11 is set to a wave shape, and more adsorption elements 30 can be filled between two adjacent baffles 11. The size of the gap between two adjacent baffles 11 is related to the size of the adsorption elements 30, which makes the overall structure of the air purifier more compact, enhances the filtration capacity of the air purifier, optimizes the filtration effect, simplifies the manufacturing process of the filter element 100 of the air purifier, reduces production costs, and also facilitates the miniaturization design of the filter element 100 of the air purifier.

[0029] According to some embodiments of the present invention, the thickness of each spoiler 11 is D, where D satisfies: 0.2mm≤D≤2mm.

[0030] When D < 0.2 mm, the thickness of each spoiler 11 is too small, resulting in poor rigidity and structural strength, as well as poor resistance to deformation and impact. This makes it prone to deformation after long-term use, affecting the normal operation of the air purifier's filter element 100 and increasing maintenance costs. When D > 2 mm, the thickness of each spoiler 11 is too large, increasing the overall weight and material cost, which is detrimental to the lightweight design of the air purifier's filter element 100. Therefore, by setting the thickness D of each spoiler 11 within the range of 0.2 mm to 2 mm, both the rigidity and structural strength of the spoiler 11 are ensured, while also facilitating the lightweight design of the air purifier's filter element 100.

[0031] According to the embodiment of the present utility model, the filter element 100 of the air purification device has a wavy baffle 11 and an adsorption element 30 is filled in the flow channel 20. Compared with the mesh layer in the existing filter element, the wavy baffle 11 has less air resistance and improves air circulation efficiency, thereby ensuring the filtration performance of the filter element 100 of the air purification device, enhancing the filtration capacity of the air purification device, optimizing the filtration effect, and facilitating the lightweight design of the filter element 100 of the air purification device.

[0032] It should be noted that the adsorption component 30 can be made of materials with high adsorption performance such as activated carbon particles or alumina. Workers can use adhesives (such as glue) to adhere the activated carbon particles to the baffle plate 11. This application does not impose specific restrictions on this.

[0033] In some alternative embodiments, the adsorption element 30 includes a plurality of solid particles, and the minimum distance between two adjacent baffles 11 in the thickness direction of the baffles 11 is equal to the total height of the solid particles.

[0034] For example, in Figure 2In the example, only a single layer of adsorbent 30 is provided, and multiple solid particles are arranged at intervals along the flow channel 20. The minimum distance between two adjacent baffles 11 in the thickness direction of the baffles 11 is equal to the total height of a single solid particle. Alternatively, the adsorbent 30 can also be provided in multiple layers, in which multiple solid particles are arranged at intervals along the flow channel 20 in each layer of adsorbent 30. In this way, the minimum distance between two adjacent baffles 11 in the thickness direction of the baffles 11 is equal to the total height of a single solid particle in each layer of adsorbent 30 in the thickness direction of the baffles 11 (not shown in the figure).

[0035] With this configuration, the gap between two adjacent baffles 11 is related to the size of the solid particles, making the overall structure of the air purifier more compact and facilitating the miniaturization design of the filter element 100 of the air purifier.

[0036] Furthermore, the flow channel 20 is filled with an adsorption element 30, and the minimum distance between two adjacent baffles 11 in the thickness direction is equal to the maximum outer diameter of the solid particles. With this arrangement, the gap between two adjacent baffles 11 is related to the size of the solid particles, making the overall structure of the air purification device more compact and facilitating the miniaturization design of the filter element 100 of the air purification device.

[0037] Specifically, the maximum outer diameter of multiple solid particles is the same, so that multiple solid particles can abut against the two adjacent baffles 11. This avoids excessive stress on some solid particles due to large size differences, and even prevents deformation or damage of solid particles after long-term use. Therefore, by making the maximum outer diameter of multiple solid particles the same, the normal use of the filter element 100 of the air purifier is guaranteed, and the service life of the filter element 100 of the air purifier is extended.

[0038] It should be noted that dimensional errors in the production of solid particles cannot be completely avoided. This application allows for the existence of dimensional errors, and workers can control the dimensional errors within a reasonable range. This application does not impose specific restrictions on this.

[0039] According to some embodiments of the present invention, each spoiler 11 includes a plurality of bent segments 111, the plurality of bent segments 111 being along the length direction of the spoiler 11 (e.g., Figure 2 The two sides are connected sequentially in the left and right directions. In the length direction of each spoiler 11, the distance between the vertices of two adjacent bending segments 111 of each spoiler 11 is L, and L satisfies: 30.0mm≤L≤40.0mm.

[0040] When L < 30.0 mm, the distance between the vertices of two adjacent bends 111 of each spoiler 11 is too small, meaning the shape of the spoiler 11 is too tortuous. This results in an overly tortuous flow path on the surface of the spoiler 11, making it difficult for the airflow to pass smoothly. Turbulence and eddies are easily generated at the bends of the spoiler, reducing airflow efficiency and making it difficult to guarantee the filtration performance of the filter element 100 of the air purifier. When L > 40.0 mm, the distance between the vertices of two adjacent bends 111 of each spoiler 11 is too large, resulting in an overly gentle flow path on the surface of the spoiler 11. The wavy spoiler 11 has a poor guiding effect on the airflow, leading to poor airflow efficiency and filtration performance of the filter element 100 of the air purifier. Therefore, by setting the distance L between the vertices of two adjacent bends 111 of each spoiler 11 within the range of 30.0 mm to 40.0 mm, the airflow efficiency is improved, thereby ensuring the filtration performance of the filter element 100 of the air purifier.

[0041] According to some embodiments of the present invention, each bending segment 111 includes a first inclined segment 1111 and a second inclined segment 1112 connected to each other, and the included angle between the first inclined segment 1111 and the second inclined segment 1112 is α, wherein α satisfies: 90°≤α≤130°.

[0042] like Figure 2 As shown, the first inclined segment 1111 is inclined upward along the length direction of the spoiler 11, and the second inclined segment 1112 is inclined downward along the length direction of the spoiler 11. The first inclined segment 1111 is connected to the second inclined segment 1112 of the same bend segment 111 on one side of the length direction of the spoiler 11, and the first inclined segment 1111 is connected to the second inclined segment 1112 of another adjacent bend segment 111 on the other side of the length direction of the spoiler 11.

[0043] When α < 90°, the angle between the first inclined section 1111 and the second inclined section 1112 is too small. When the airflow passes through the connection of the first inclined section 1111 and the second inclined section 1112, it is easy to turn sharply due to the sudden change in angle, causing the airflow to separate from the baffle 11 in advance, generating turbulence and eddies. As a result, the airflow accumulates at the connection of the first inclined section 1111 and the second inclined section 1112 and is difficult to continue flowing, resulting in poor air circulation efficiency and filtration performance of the filter element 100 of the air purification device.

[0044] When α > 130°, the angle between the first inclined section 1111 and the second inclined section 1112 is too large, meaning the bending section 111 is nearly straight. The airflow passes roughly in a straight line along the surface of the bending section 111, failing to effectively change the airflow direction. Consequently, the contact rate between the airflow and the adsorption element 30 is poor, affecting the filtration effect of the filter element 100 in the air purifier. Furthermore, it increases the overall volume of the baffle 11, which is detrimental to the miniaturization design of the filter element. Therefore, by setting the angle α between the first inclined section 1111 and the second inclined section 1112 between 90° and 130°, both the airflow efficiency and filtration performance of the filter element 100 in the air purifier are ensured, while also facilitating the miniaturization design of the filter element.

[0045] In some optional embodiments, the two outermost bends 111 of the plurality of bends 111 are the first bend 1113 and the second bend 1114. Each spoiler 11 also includes a first extension 112 and a second extension 113. The two ends of the first extension 112 are connected to the frame 40 and the first inclined section 1111 of the first bend 1113, respectively. The two ends of the second extension 113 are connected to the frame 40 and the second inclined section 1112 of the second bend 1114, respectively.

[0046] like Figure 2 As shown, the first extension segment 112 and the second extension segment 113 both extend along the length direction of the spoiler 11. The first extension segment 112 and the second extension segment 113 serve as transition structures between the spoiler 11 and the frame 40, which can increase the connection area between the spoiler 11 and the frame 40, thereby increasing the connection strength between the spoiler 11 and the frame 40 and preventing the spoiler 11 from detaching from the frame 40 and affecting the normal use of the filter element 100 of the air purification device.

[0047] Specifically, the angle between the first extension segment 112 and the first inclined segment 1111 of the first bending segment 1113 is β, and the angle between the second extension segment 113 and the second inclined segment 1112 of the second bending segment 1114 is γ. β and γ satisfy: 150︒≤β<180︒, 150︒≤γ<180︒.

[0048] When β < 150°, the angle between the first extension section 112 and the first inclined section 1111 of the first bend section 1113 is too small. When the airflow passes through the connection between the first extension section 112 and the first inclined section 1111 of the first bend section 1113, it is prone to abruptly changing direction due to the sudden angle change. This causes the airflow to separate prematurely from the spoiler 11, generating turbulence and eddies. Consequently, the airflow accumulates at the connection between the first extension section 112 and the first inclined section 1111 of the first bend section 1113, making it difficult for the airflow to continue. This results in poor airflow efficiency and filtration performance of the filter element 100 of the air purifier. Therefore, by setting the angle β between the first extension section 112 and the first inclined section 1111 of the first bend section 1113 in the range of 150° to 180°, the airflow efficiency and filtration performance of the filter element 100 of the air purifier are ensured.

[0049] When γ < 150°, the angle between the second extension section 113 and the second inclined section 1112 of the second bend section 1114 is too small. When the airflow passes through the connection between the second extension section 113 and the second inclined section 1112 of the second bend section 1114, it is prone to abruptly turning due to the sudden change in angle. This causes the airflow to separate prematurely from the spoiler 11, generating turbulence and eddies. Consequently, the airflow accumulates at the connection between the second extension section 113 and the second inclined section 1112 of the second bend section 1114, making it difficult for the airflow to continue. This results in poor airflow efficiency and filtration performance of the filter element 100 of the air purifier. Therefore, by setting the angle γ between the second extension section 113 and the second inclined section 1112 of the second bend section 1114 within the range of 150° to 180°, the airflow efficiency and filtration performance of the filter element 100 of the air purifier are ensured.

[0050] According to some embodiments of the present invention, the width direction of the spoiler 11 (e.g., Figure 1 The two ends of the flow channel 20 (in the front and back direction) are the air inlet and the air outlet, respectively. Along the direction from the air inlet to the air outlet, the density of the adsorbent 30 in the flow channel 20 gradually increases (not shown in the figure).

[0051] With this configuration, the adsorption element 30 near the air inlet has a lower density, which can intercept large particulate impurities (such as dust and fibers) in the airflow, while the adsorption element 30 near the air outlet has a higher density, which can intercept fine impurities (such as bacteria) in the airflow. This allows the filter element 100 of the air purifier to perform more comprehensive filtration of the airflow, thereby improving the filtration capacity of the filter element 100 of the air purifier.

[0052] According to some other embodiments of the present invention, the filter element 100 of the air purification device further includes a plurality of support structures (not shown in the figure), all of which are disposed in the flow channel 20. The plurality of support structures are arranged at intervals along the length direction of the baffle 11, and each support structure extends along the width direction of the baffle 11.

[0053] The support structure improves the overall structural stability of the filter element 100 of the air purifier. Furthermore, by setting up the support structure, the gap between two adjacent baffles 11 is increased, allowing for the placement of multiple adsorption elements 30 between the two adjacent baffles 11, thereby improving the filtration performance of the filter element 100 of the air purifier.

[0054] It should be noted that the supporting structure can be a column, hollow tube, or other similar structure, and this application does not impose any specific restrictions on it.

[0055] According to some embodiments of this utility model, the filter element 100 of the air purification device further includes two ventilation elements 50. The two ventilation elements 50 are respectively disposed at the air inlet end and air outlet end of the baffle 11, and the cross-sectional area of ​​each ventilation element 50 is larger than the cross-sectional area of ​​the carrier 10 in the projection plane along the length direction of the baffle 11. By providing ventilation elements 50 at the air inlet end and air outlet end of the baffle 11, and making the cross-sectional area of ​​each ventilation element 50 larger than the cross-sectional area of ​​the carrier 10, the ventilation elements 50 can completely cover the carrier 10, which can prevent the adsorption element 30 from falling off from the air inlet end and air outlet end of the baffle 11, ensuring the filtration performance of the filter element 100 of the air purification device, reducing the maintenance cost of the filter element 100 of the air purification device, and the ventilation element 50 located at the air inlet end can filter some large particulate impurities in the airflow, playing a pre-filtration role.

[0056] It should be noted that the ventilation element 50 can be a protective net, and this application does not impose specific restrictions on it.

[0057] According to some other embodiments of the present invention, there are multiple carriers 10, which are arranged along the width direction of the spoiler 11. The two ends of the spoiler 11 in the width direction are the air inlet and the air outlet, respectively. Along the direction from the air inlet to the air outlet, the included angle between the first inclined section 1111 and the second inclined section 1112 of the multiple carriers 10 gradually decreases.

[0058] With this configuration, due to the higher airflow velocity and pressure at the air inlet, the angle between the first inclined section 1111 and the second inclined section 1112 near the air inlet is larger, which can guide the high-speed airflow to quickly diffuse throughout the width of the entire filter element, improving the filtration efficiency of the filter element 100 of the air purifier. On the other hand, the angle between the first inclined section 1111 and the second inclined section 1112 near the air outlet is smaller, the airflow turns multiple times and stays for a longer time, which can fully contact the adsorption element 30, improving the filtration effect of the filter element 100 of the air purifier.

[0059] According to some embodiments of the present invention, the spoiler 11 is a thermoformed part, which reduces the production cost of the filter element 100 of the air purifier, improves the adaptability of the filter element 100 of the air purifier, and is conducive to the lightweight design of the filter element 100 of the air purifier.

[0060] The specific assembly process of the filter element 100 of the air purification device according to an embodiment of the present utility model is as follows: First, the baffle 11 in the carrier 10 is sprayed with glue on one side by an automated glue spraying equipment. After the glue spraying is completed, the baffle 11 enters the drying line. After the glue dries, it enters the automatic carbon sprinkling machine to stick the adsorption component 30 (such as activated carbon) onto the baffle 11. Then, it is automatically re-stacked into the required size by the production line. The baffle 11 is then installed into the frame 40. Finally, the ventilation component 50 (such as a protective net) is installed.

[0061] An air purification device (not shown) according to a second aspect embodiment of the present invention includes a filter element 100 of the air purification device according to the first aspect embodiment of the present invention.

[0062] According to the embodiment of the present utility model, the air purification device, by adopting the filter element 100 of the air purification device, ensures the air circulation efficiency and filtration performance of the air purification device, the overall structure of the air purification device is more compact, the filtration capacity of the air purification device is enhanced, the filtration effect is optimized, the manufacturing process of the air purification device is simplified, the production cost is reduced, and it is also conducive to the miniaturization design of the air purification device.

[0063] It should be noted that, under the premise of the same filter element thickness, the air resistance of the air purifier filter element 100 is reduced by 25%, the CADR (Clean Air Delivery Rate) is increased by 11%, the deodorization performance remains unchanged, and automated production can be achieved, effectively reducing production costs.
