Through this clamping design, the air inlet cover 100 can be quickly and conveniently installed and disassembled without the need for additional tools, which greatly simplifies the operation steps of the user and improves the convenience of maintenance and cleaning.

[0038] The outer surface of the convex column 170 is provided with a plurality of convex ribs 180, which are arranged along the length direction of the convex column 170, and are suitable for mounting the air inlet cover 100 on the support column 200. The design of the convex ribs 180 increases the contact area between the convex column 170 and the clamping part, thereby improving the stability of the connection between the air inlet cover 100 and the support column 200, and preventing loosening or falling off due to vibration or external force during use.

[0039] The height of the support column 200 is A, which satisfies 22mm≤A≤28mm. It can ensure that a suitable air inlet channel is formed between the air inlet cover 100 and the smoke pipe 160. The support column 200 in this height range can provide sufficient space for the oil fume to smoothly enter the smoke pipe 160, avoiding the problem of poor air inlet or blockage due to improper height, and improving the efficiency of oil fume extraction.

[0040] The center of the air inlet cover 100 is also provided with a convex part 230, which abuts against the center of the first filter layer 120 and the second filter layer 130 when the air inlet cover 100 is completely mounted on the support frame 110, so that the first filter layer 120 and the second filter layer 130 form a conical shape. The conical structure helps to optimize the flow path of the oil fume, so that the oil fume flows more centrally to the middle, thereby improving the collection efficiency of the oil fume. The conical structure reduces the dead angle in the filter layer, avoids the accumulation of oil fume in the filter layer, and improves the collection and filtering effect of the oil fume.

[0041] It can be understood that the air inlet cover 100 is provided with four convex columns 170, which are connected between the four convex columns 170 and the support column 200 through interference fit.

The top of the support frame 110 is provided with eight support columns 200, which are uniformly and circumferentially arranged along the top of the support frame 110. When the support frame 110 is tightly clamped on the top of the smoke pipe 160, the eight support columns 200 can press the first filter layer 120 and the second filter layer 130, so as to ensure that the filter layer does not move during use. The pressing action of the support column 200 makes the first filter layer 120 and the second filter layer 130 be firmly fixed at the air inlet, avoiding movement caused by vibration or air flow, and ensuring the stability and reliability of the filtering effect.

[0043] It can be understood that the bottom of the smoke pipe 160 is provided with a metal blocking net, which effectively prevents users from being injured by accidentally touching the negative pressure fan during cleaning, improving the safety of the device.

[0047] The first filter layer 120 is a filter cotton filter layer, and the second filter layer 130 is an activated carbon filter layer. A multi-level filtration system is formed. The filter cotton layer first intercepts large-particle oil fume and impurities, and the activated carbon layer further adsorbs small-particle matter and odors. This multi-level filtration method significantly improves the overall filtration efficiency and purification effect.

[0048] Referring to Figures 1 to 3 In the first aspect embodiment, the smoke pipe 160 is a hollow pipe body for guiding the flow of oil fume, and the negative pressure fan is arranged at the bottom of the smoke pipe 160 for generating strong suction to quickly extract the oil fume generated during cooking.

[0049] The support frame 110 is arranged at the top of the smoke pipe 160 and used for fixing and supporting the air inlet cover 100. The support frame 110 is made of high-temperature-resistant material and has good high-temperature resistance and corrosion resistance. The air inlet cover 100 is installed on the upper part of the support frame 110 in a clamping manner and forms an oil fume recovery channel with the support frame 110. The air inlet cover 100 is made of plastic material and is light and easy to disassemble and clean. The top of the support frame 110 is provided with eight support columns 200 which are evenly and circumferentially arranged along the top of the support frame 110. Each support column 200 has a height of 25 mm and is provided with a clamping portion at the top, which is adapted to the protruding column 170 on the air inlet cover 100. The air inlet cover 100 is provided with the protruding column 170 which is adapted to the clamping portion of the support column 200. The outer surface of the protruding column 170 is provided with a plurality of protruding ribs 180 extending in the length direction, which increases the contact area between the air inlet cover 100 and the support column 200 and improves the stability of the connection.

[0050] The oil collecting cup 150 is arranged below the filter assembly and has a funnel-shaped design. The side wall of the oil collecting cup 150 is provided with a plurality of reinforcing ribs which extend from the top of the oil collecting cup 150 to the containing cavity and enhance the structural strength of the oil collecting cup 150. The oil collecting net 140 also has a funnel-shaped design and is sleeved to the inner side wall of the oil collecting cup 150, which can effectively intercept the oil droplets in the oil fume and prevent the oil droplets from being directly discharged into the environment through the filter layer. The bottom of the oil collecting cup 150 is provided with a containing cavity which is suitable for containing the oil fume after condensation and avoids the accumulation of oil droplets in the filter assembly, thereby improving the collection efficiency of the oil fume.

[0051] With reference to Figure 4 According to the second aspect of the utility model, the frying and baking tray 210 is integrated with the efficient oil fume recovery device 220, which can quickly extract and filter the oil fume during the cooking process, significantly reduce the emission of the oil fume, improve the kitchen environment and provide a cleaner and healthier cooking experience. The integrated design of the frying and baking tray 210 and the oil fume recovery device 220 makes the overall structure more compact and saves the kitchen space. The user can enjoy the efficient oil fume processing function without additional installation of the range hood or other large equipment.

[0052] When the user starts the frying and baking tray 210, the negative pressure fan starts to work and generates strong suction force to quickly extract the oil fume generated during the cooking process through the smoke pipe 160. The extracted oil fume first passes through the first filter layer 120, and the filter cotton can effectively intercept and filter the large-particle oil fume and impurities. The oil fume passing through the first filter layer 120 then enters the second filter layer 130, and the activated carbon can adsorb the odor and small particles in the oil fume to further purify the oil fume.

[0053] When the user starts the frying and baking tray 210, the negative pressure fan starts to work and generates strong suction force to quickly extract the oil fume generated during the cooking process through the smoke pipe 160. The extracted oil fume first passes through the first filter layer 120, and the filter cotton can effectively intercept and filter the large-particle oil fume and impurities. The oil fume passing through the first filter layer 120 then enters the second filter layer 130, and the activated carbon can adsorb the odor and small particles in the oil fume to further purify the oil fume.

[0054] The filtered oil fume continues to flow downward, passes through the funnel-shaped oil collecting net 140, and the oil droplets are intercepted and flow into the containing cavity at the bottom of the oil collecting cup 150. The condensed oil in the containing cavity can be kept clean and efficient operation of the device by regular cleaning.
