Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0076] Please refer to Figure 1 , Figure 2 and Figure 4 The filter element 10 of this application includes a mounting base 1 and a honeycomb layer 2. The honeycomb layer 2 is fixed to the mounting base 1 and includes a frame 21 and a filter body 22. The frame 21 is provided with a filter channel 23, and the filter body 22 is disposed within the filter channel 23. When air flows through the filter channel 23, it can interact with the filter body 22, and the filter body 22 can decompose harmful substances in the air. At least a portion of the filter channel 23 is curved, which forces the airflow path to lengthen, increasing the contact time between harmful substances in the air and the filter body 22, thereby improving the decomposition rate of harmful substances by the filter body 22. Furthermore, the curved design of the portion of the filter channel 23 allows the air to generate local vortices within the filter channel 23, effectively increasing the residence time of the airflow within the filter channel 23, ensuring sufficient contact between the air and the filter body 22, and improving the decomposition effect of the filter body 22 on harmful substances.

[0077] In this embodiment, the shape of the filter element 22 is not limited; it can be block-shaped, granular, or other shapes. The type of hazardous substance is not limited; it can include formaldehyde, toluene, benzene, or other hazardous substances. The number of filter channels 23 is not limited; there can be one or more filter channels 23.

[0078] In this embodiment, the connection relationship between the mounting base 1 and the honeycomb layer 2 is not limited. The mounting base 1 and the honeycomb layer 2 can be connected by tenon and mortise joints, adhesive bonding, snap-fit ​​24, screw connection or other connection methods.

[0079] In this embodiment, the shape of the mounting base 1 is not limited; it can be box-shaped, cylindrical, frame-shaped, or other shapes. The shape of the honeycomb layer 2 is not limited; it can be cuboid, cylindrical, frame-shaped, or other shapes.

[0080] In this embodiment, the filter channel 23 can be partially or entirely curved, and no limitation is made here.

[0081] In one embodiment, reference Figure 1 The filter element 10 also includes a first filter layer 3. The first filter layer 3 and the honeycomb layer 2 are stacked along the air intake direction. Air can flow through the first filter layer 3 and the honeycomb layer 2 in sequence. The first filter layer 3 can block pollutant particles and reduce the amount of pollutant particles entering the honeycomb layer 2.

[0082] In this embodiment, the material of the first filter layer 3 may include at least one of metal, plastic, and synthetic fiber. For example, the first filter layer 3 may include, but is not limited to, aluminum alloy mesh, titanium alloy mesh, stainless steel mesh, and plastic mesh.

[0083] In one embodiment, the first filter layer 3 is detachably connected to the mounting base 1. For example, the first filter layer 3 and the mounting base 1 can be connected by tenon and mortise joints, snap fasteners 24, magnetic connections, or other detachable connection methods. The detachable connection between the first filter layer 3 and the mounting base 1 facilitates the replacement and cleaning of the first filter layer 3, effectively improving the service life of the subsequent filter element 10.

[0084] In one embodiment, the first filter layer 3 has mesh openings with an average pore size between 0.1 μm and 200 μm, preferably between 1 μm and 5 μm. Optionally, the average pore size can be any one or any two of 0.1 μm, 1 μm, 3 μm, 10 μm, 50 μm, 100 μm, 130 μm, 170 μm, and 200 μm, and is not limited herein. Setting the mesh size of the first filter layer 3 between 0.1 μm and 200 μm can effectively filter large particulate matter such as ground dust, sand, hair, plant fluff, insects, debris, and large pollen particles, while reducing airflow resistance.

[0085] In one embodiment, reference Figure 1 The filter element 10 also includes a first magnetic element 4, which is fixed to the first filter layer 3;

[0086] The mounting base 1 is provided with a second magnetic member 5 that attracts the first magnetic member 4, and the second magnetic member 5 is magnetically connected to the first magnetic member 4. The first filter layer 3 is magnetically connected to the mounting base 1, which facilitates the disassembly, replacement and cleaning of the first filter layer 3, effectively improving the service life of the subsequent filter element 10.

[0087] In this embodiment, the first magnetic attractor 4 and the second magnetic attractor 5 can both be magnets; or, one of the first magnetic attractor 4 and the second magnetic attractor 5 can be a magnet and the other can be a metal, which is not limited here.

[0088] In this embodiment, the shapes of the first magnetic attractor 4 and the second magnetic attractor 5 are not limited, and the first magnetic attractor 4 and the second magnetic attractor 5 can be block-shaped, strip-shaped or other shapes.

[0089] In one embodiment, a first magnetic member 4 surrounds the periphery of the first filter layer 3, and a second magnetic member 5 surrounds the periphery of the mounting base 1. The first magnetic member 4 and the second magnetic member 5 are closely connected. This allows the periphery of the first filter layer 3 to be closely connected to the mounting base 1, ensuring a tight and seamless fit between the edges of the first filter layer 3 and the mounting base 1. This provides good sealing, preventing air leakage at the connection between the first filter layer 3 and the mounting base 1, thereby improving the air filtration effect.

[0090] In one embodiment, reference Figure 1 and Figure 3 The filter element 10 also includes a second filter layer 6. The honeycomb layer 2 and the second filter layer 6 are stacked along the air intake direction, and the second filter layer 6 can block pollutant particles. In this embodiment, air can flow through the honeycomb layer 2 and the second filter layer 6 in sequence. The second filter layer 6 can block pollutant particles and reduce the number of pollutant particles entering the filter.

[0091] In this embodiment, the average particle size of the pollutant particles is between 0.05 μm and 20 μm. Optionally, the average particle size of the pollutant particles can be any one or any two of 0.05 μm, 1 μm, 5 μm, 13 μm, 20 μm, etc., and is not limited here.

[0092] In one specific embodiment, the first filter layer 3, the honeycomb layer 2, and the second filter layer 6 are stacked along the air intake direction, and air can flow through the first filter layer 3, the honeycomb layer 2, and the second filter layer 6 in sequence.

[0093] In one embodiment, the second filter layer 6 includes formaldehyde-removing microparticles 61 and filter paper 62, with the formaldehyde-removing microparticles 61 fixed to the filter paper 62; the filter paper 62 can filter PM2.5, and the formaldehyde-removing microparticles 61 can decompose undecomposed formaldehyde in the honeycomb layer 2. This further improves the removal effect of the filter element 10 on harmful substances.

[0094] In one embodiment, the second filter layer (6) may also consist only of filter paper (62) and not include formaldehyde-removing particles 61, which is not limited here.

[0095] In this embodiment, the second filter layer 6 can be formed by folding filter paper 62 containing formaldehyde-removing particles 61.

[0096] In one embodiment, reference Figure 1 and Figure 3 The second filter layer 6 is detachably connected to the mounting base 1. For example, the second filter layer 6 and the mounting base 1 can be connected by tenon and mortise joints, snap fasteners 24, magnetic connections, or other detachable connection methods. The detachable connection between the second filter layer 6 and the mounting base 1 facilitates the replacement and cleaning of the second filter layer 6, effectively improving the service life of the subsequent filter element 10.

[0097] In one specific embodiment, reference is made to Figure 1 The mounting base 1 includes a surrounding wall 11. A slot 12 is provided on the side of the surrounding wall 11 facing the frame. The slot 12 is a dovetail-shaped groove. The average thickness of the surrounding wall 11 is 3mm-10mm. The dovetail-shaped grooves are located around the perimeter of the surrounding wall 11. The bottom of the dovetail-shaped groove is 1mm-7mm from the outer edge of the surrounding wall 11, and the width of the bottom is 10mm-20mm. The opening of the dovetail-shaped groove is flush with the inner edge of the surrounding wall 11. A protrusion 63 is provided on the outer wall of the second filter layer 6 to mate with the dovetail-shaped groove. The protrusion 63 is inserted into the dovetail-shaped groove and tenon-jointed with it.

[0098] In one embodiment, the honeycomb layer 2 is detachably connected to the mounting base 1. For example, the honeycomb layer 2 and the mounting base 1 can be connected by tenon and mortise joints, snap fasteners 24, magnetic connections, or other detachable connection methods. The detachable connection between the second honeycomb layer 2 and the mounting base 1 facilitates the replacement and cleaning of the honeycomb layer 2, effectively improving the service life of the subsequent filter element 10.

[0099] In one embodiment, the mounting base 1 includes a surrounding wall 11, with a slot 12 on the side of the surrounding wall 11 facing the frame; the honeycomb layer 2 also includes a buckle 24 adapted to the slot 12, the buckle 24 being disposed on the outer side wall 25 of the honeycomb layer 2, and the buckle 24 being tenon-and-mortise connected to the slot 12. The tenon-and-mortise connection ensures a firm bond between the honeycomb layer 2 and the mounting base 1, and the connection between the buckle 24 and the slot 12 has a good sealing effect and a simple connection structure.

[0100] In one embodiment, reference Figure 5and Figure 6 The frame includes a spiral sidewall 251 surrounding the filter channel 23, which causes at least a portion of the filter channel 23 to bend. This bending of the channel forces an increased airflow path, increasing the contact time between harmful substances in the air and the filter element 22, thereby improving the decomposition rate of harmful substances by the filter element 22. Furthermore, the partial bending of the filter channel 23 allows for the generation of localized vortices within the filter channel 23, effectively increasing the residence time of the airflow within the filter channel 23 and ensuring sufficient contact between the air and the filter element 22, thus enhancing the decomposition effect of the filter element 22 on harmful substances.

[0101] In one embodiment, the helical angle α of the spiral sidewall 251 is between 30° and 180°. Preferably, the helical angle α of the spiral sidewall 251 is between 30° and 180°. When the helical angle of the spiral sidewall 251 is less than 30°, the airflow tends to pass through the filter channel 23 in a straight line, resulting in a short contact time between the air and the filter element 22, leading to an unsatisfactory decomposition effect of the filter element 22 on harmful substances. When the helical angle of the spiral sidewall 251 is greater than 180°, the airflow path tends to be too tortuous, increasing the pressure drop and consequently causing a decrease in filter airflow.

[0102] In this embodiment, the helical angle of the helical sidewall 251 can be any one or any two of 30°, 70°, 90°, 100°, 120°, 150°, 180°, etc., and is not limited here.

[0103] In one embodiment, the cross-sectional shape of the filter channel is circular, and the average inner diameter of the filter channel is between 2mm and 10mm. Optionally, the average inner diameter of the filter channel can be any one or any two of 2mm, 4mm, 6mm, 8mm, and 10mm, and is not limited here. In this embodiment, when the average inner diameter of the filter channel is less than 2mm, it is easy to cause increased air resistance, decreased airflow from the filter, and increased energy consumption. When the average inner diameter of the filter channel is greater than 10mm, it is easy to cause the filter body 22 to stack or the gap between the filter body 22 and the side wall 25 of the filter channel 23 to be too large, reducing the effective filtration area of ​​the honeycomb layer 2, making it easier for pollutant particles to penetrate the filter element 10, resulting in reduced filtration efficiency.

[0104] In one embodiment, the cross-sectional shape of the filter channel is polygonal, and the average diameter of the inscribed circle of the polygon is between 2 mm and 10 mm. Optionally, the average diameter of the inscribed circle of the polygon can be any one or any two of 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc., and is not limited here. In this embodiment, when the average diameter of the inscribed circle of the polygon is less than 2 mm, it is easy to cause increased air resistance, decreased airflow from the filter, and increased energy consumption. When the average diameter of the inscribed circle of the polygon is greater than 10 mm, it is easy to cause the filter body 22 to stack or the gap between the filter body 22 and the side wall 25 of the filter channel 23 to be too large, reducing the effective filtration area of ​​the honeycomb layer 2, making it easier for pollutant particles to penetrate the filter element 10, resulting in reduced filtration efficiency.

[0105] In one embodiment, the filter channel has an air inlet and an air outlet, the inner diameter of the air inlet being the same as the inner diameter of the air outlet.

[0106] In one embodiment, the filter channel has an air inlet and an air outlet. The inner diameter of the air inlet is larger than the inner diameter of the air outlet, and the difference between the inner diameters of the air inlet and the air outlet is between 2 mm and 5 mm. Optionally, the difference between the inner diameters of the air inlet and the air outlet can be any one or any two of 2 mm, 3 mm, 4 mm, 5 mm, etc., and is not limited here. When the difference between the inner diameters of the air inlet and the air outlet is too large, it can easily cause fatigue fracture of the sidewall of the filter channel at the air outlet due to airflow impact, shortening its lifespan. Setting the difference between the inner diameters of the air inlet and the air outlet within the above-mentioned range can maintain a stable airflow from the filter and avoid the negative impact of extreme dimensional differences.

[0107] In this embodiment, the inner diameter of the air inlet is larger than the inner diameter of the air outlet, which can reduce the initial resistance of airflow, avoid high-load operation of the filter fan, and reduce energy consumption; at the same time, the inner diameter of the air outlet is smaller than the inner diameter of the air inlet, which can accelerate the airflow, compensate for the resistance caused by filtration, and maintain stable air volume.

[0108] In one embodiment, reference Figure 7 and Figure 8 The frame includes an arcuate sidewall 252 surrounding the filter channel 23, which causes at least a portion of the filter channel 23 to be curved. The curved channel forces an increased airflow path, increasing the contact time between harmful substances in the air and the filter element 22, thereby improving the decomposition rate of harmful substances by the filter element 22. Furthermore, the partial curvature of the filter channel 23 allows for the generation of localized vortices within the filter channel 23, effectively increasing the residence time of the airflow within the filter channel 23 and ensuring sufficient contact between the air and the filter element 22, thus enhancing the decomposition effect of the filter element 22 on harmful substances.

[0109] In one embodiment, the central angle β of the arc-shaped sidewall 252 is greater than 0° and less than or equal to 120°. Preferably, the central angle β of the arc-shaped sidewall 252 is between 10° and 85°. When the central angle of the arc-shaped sidewall 252 is greater than 120°, the airflow tends to pass through the filter channel 23 in a straight line, resulting in a short contact time between the air and the filter body 22, leading to an unsatisfactory decomposition effect of the filter body 22 on harmful substances. In this embodiment, the central angle of the arc-shaped sidewall 252 can be any one or any two of 1°, 10°, 30°, 60°, 90°, 120°, etc., and is not limited here.

[0110] In one embodiment, there are multiple arc-shaped sidewalls 252. In this embodiment, the number of arc-shaped sidewalls 252 can be two, three, or more, and is not limited thereto. Having multiple arc-shaped sidewalls 252 can increase the airflow path, increase the contact time between harmful substances in the air and the filter 22, and improve the decomposition rate of harmful substances in the air by the filter 22.

[0111] In one embodiment, reference Figure 9 and Figure 10 The frame includes sidewalls 25 surrounding the filter channel 23, and the sidewalls 25 include at least two connecting walls 253 connected at an angle to make at least a portion of the filter channel 23 bend. The bend in the channel forces an increase in the airflow path, increasing the contact time between harmful substances in the air and the filter element 22, thereby improving the decomposition rate of harmful substances in the air by the filter element 22. In addition, the partial bend in the filter channel 23 allows the air to generate local vortices within the filter channel 23, effectively increasing the residence time of the airflow within the filter channel 23, ensuring sufficient contact between the air and the filter element 22, and improving the decomposition effect of the filter element 22 on harmful substances.

[0112] In one embodiment, the included angle between two adjacent connecting walls 253 is greater than 90° and less than 180°; preferably, the included angle between two adjacent connecting walls 253 is greater than 100° and less than 180°. In this embodiment, the included angle between two adjacent connecting walls 253 can be any one or any two of 91°, 120°, 140°, 160°, 179°, etc., and is not limited here. Setting the included angle between two adjacent connecting walls 253 to be greater than 90° and less than 180° can increase the airflow path and generate local vortices in the filter channel 23, increasing the contact time between harmful substances in the air and the filter body 22, thereby improving the decomposition effect of the filter body 22 on harmful substances; at the same time, it can prevent the airflow path from being too tortuous and reduce the attenuation of filter airflow.
