Description

Technical Field

[0001] This invention relates to the field of air purifiers, and particularly to an air purifier for oil fume pollution. Background Technology

[0002] Air purifiers for cooking fumes are air purification devices that filter air in environments with cooking fumes. They are suitable for home kitchens and restaurants, and can effectively deal with cooking fume pollution, making them widely used.

[0003] However, in current air purifier technology, air purification devices targeting cooking fumes are typically designed with filters to adsorb both fumes and particulate matter. However, these common designs generally have some shortcomings. First, most devices use a fixed filtration path; regardless of whether the air contains ordinary particulate matter or cooking fumes, the air flows through the same combination of filter media. This single-mode processing method is inefficient. When processing ordinary air, the high-capacity oil fume filter media may be consumed prematurely, while when processing high-concentration oil fumes, ordinary filter elements are easily clogged by grease, leading to decreased purification effect, increased air resistance, and increased energy consumption. It is difficult to achieve intelligent, on-demand use of the filter media while ensuring purification effect. Second, the grease components in cooking fumes are sticky and easily adhere to and clog the microporous structure of the filter media. When cooking fumes directly contact the filter media used to filter PM2.5 and other fine particles... When high-efficiency filter elements, such as HEPA filters, are used, they quickly become ineffective. This not only wastes the relatively expensive core filter element but also significantly increases the user's operating and maintenance costs. Finally, there are deficiencies in oil collection and cleaning. Many devices rely solely on filter media to adsorb grease, but the intercepted grease still accumulates inside the filter or in the machine's air duct and cannot be effectively discharged. This leads to a deterioration of the internal hygiene of the equipment, producing odors and breeding bacteria. Moreover, it is extremely inconvenient for users to clean, often requiring the disassembly of the entire filter unit for tedious cleaning. At the same time, replacing filter media usually requires disassembling and reassembling each piece, which is cumbersome. Furthermore, the internal structure may be difficult to disassemble due to oil stains, increasing the difficulty and time cost of daily maintenance. Summary of the Invention

[0004] The main objective of this invention is to provide an air purifier that effectively solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An air purifier for oil fume pollution includes a mounting frame, an air inlet mesh plate, and an air guide top plate. The air inlet mesh plate is fixedly installed at the front and rear ends of the mounting frame, and the air guide top plate is fixedly installed at the top of the mounting frame. A snap-fit ​​plate is integrally formed on the top of the air inlet mesh plate. A switching fan structure is provided on the top of the mounting frame. A pull-out motor is fixedly installed on one side of the mounting frame. A side cover plate is movably installed on one side of the mounting frame below the pull-out motor. An oil collection box is fixedly installed at the bottom of one side of the side cover plate. A partition sealing plate is fixedly installed in the center of the interior of the mounting frame. A purification filter element is fixedly installed on one side of the partition sealing plate. A filter plate mounting frame is fixedly installed inside the mounting frame on the other side of the partition sealing plate. A side air guide hood is fixedly installed on one side of the filter plate mounting frame. A switch motor is fixedly installed at the upper end of the side air guide hood. A switch motor is movably installed inside the side air guide hood. A top air guide hood is fixedly installed at the upper end of the filter plate mounting frame. Activated carbon filter plates are fixedly installed at both the front and rear ends of the filter plate mounting frame. A mesh frame mounting frame is fixedly installed above the front and rear ends of the filter plate mounting frame. An oil-separating structure is provided at the lower end of the mesh frame mounting frame.

[0007] As a further embodiment of the present invention, the switching fan structure includes a sealing baffle, a push-pull toothed plate, a sliding plate, a fan box, an exhaust fan, and an exhaust port. The sealing baffle and the sliding plate are located at the top of the mounting frame. The sealing baffle and the sliding plate are fixedly connected in parallel. The push-pull toothed plate is embedded in the bottom surface of the sealing baffle. The fan box is fixedly installed at the upper end of the sliding plate. The exhaust fan is rotatably installed inside the fan box. The exhaust port is opened on one side of the fan box.

[0008] As a further embodiment of the present invention, the snap-fit ​​plate is snapped into the front and rear of the sliding plate and movably connected thereto. An air guide hole is provided inside the air guide top plate. The sealing baffle and the sliding plate are both attached to the upper end of the air guide top plate. The fan box is connected to the interior of the mounting frame through the sliding plate and the air guide hole.

[0009] As a further embodiment of the present invention, the pull-out motor is located below the sealing baffle, and the rotating shaft of the pull-out motor is connected to the push-pull gear plate through gear meshing.

[0010] As a further embodiment of the present invention, the front and rear ends of the air guide plate and the partition sealing plate are fitted and connected to the front and rear air inlet mesh plates, and the purification filter element and the filter plate mounting frame are both located between the two air inlet mesh plates.

[0011] As a further embodiment of the present invention, the air outlets of the purification filter element and the top air guide cover both face the air guide top plate, and the partition sealing plate is fixedly connected to the top of the purification filter element.

[0012] As a further embodiment of the present invention, the rotating shaft of the switch motor passes through the side air guide cover and is fixedly connected to the switch plate, and the side air guide cover passes through the partition sealing plate and is located on one side of the purification filter element.

[0013] As a further embodiment of the present invention, the oil-separating structure includes a filter frame, an oil-separating filter, and a flow guide channel. The filter frame is movably installed at the lower end of the mesh frame mounting frame, the oil-separating filter is fixedly installed on the inner side of the filter frame, and the flow guide channel is fixedly installed below the front end of the filter frame.

[0014] As a further embodiment of the present invention, the guide channel is located below the oil separator screen, one end of the guide channel passes through one side of the mounting frame and is inserted into the oil collection box, and the two oil separator screens are located in front of and behind the two activated carbon filter plates, respectively.

[0015] As a further embodiment of the present invention, a support bracket is fixedly installed at the lower end of the mounting frame, the support bracket is arranged parallel to the oil collection box, and a switch grille is rotatably installed on one side of the air intake grille and the adjacent surface of the mounting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: it can automatically switch the working mode according to the air pollution situation. When there is no oil fume in the air, the fan box is located on the right side, and the air is filtered efficiently only through the purification filter element, mainly targeting ordinary particulate matter. When there is oil fume in the air, the fan box switches to the left side, and the air is filtered sequentially through the oil-separating filter and the activated carbon filter plate. The former can filter out grease, and the latter can adsorb smoke particles and odors, specifically targeting oil fume pollution. When the oil fume concentration is extremely high, the enhanced mode can also be activated. The fan box is located on the right side, but the right air intake is closed and the side air guide hood is opened, so that the air passes through the oil-separating filter, the activated carbon filter plate and the purification filter element in sequence to achieve three-layer deep filtration. This design improves the targeting and efficiency of purification.

[0017] By separating the path of the grease trap and activated carbon filter for fume filtration from that of the ordinary air filtration filter, direct contact between grease and fume is avoided, preventing rapid contamination and clogging of potentially expensive air filtration filters. This prevents inadequate filtration and rapid consumption of consumables during fume filtration, thus extending the lifespan of the core filter and reducing maintenance costs. The specially designed grease trap effectively intercepts airborne grease particles, which drip down into the guide channel and eventually flow into a removable grease collection box for centralized collection. This achieves automatic separation and collection of grease, facilitating cleaning and preventing grease buildup inside the machine. Furthermore, the activated carbon filter and grease trap are integrated into the filter plate mounting frame, resulting in a compact structure with a small footprint. Combined with the movable side cover, the entire filter plate mounting frame can be easily removed for quick replacement of the activated carbon filter and grease trap, creating a modular structure that greatly simplifies daily maintenance and consumable replacement procedures.

[0029] like Figures 1-8As shown, this is an air purifier for treating oil fume pollution. Please refer to it carefully. Figures 1-8 The system includes a mounting frame 1, an air inlet mesh plate 2, and an air guide top plate 11. The air inlet mesh plate 2 is fixedly installed at the front and rear ends of the mounting frame 1, and the air guide top plate 11 is fixedly installed at the upper end of the mounting frame 1. A snap-fit ​​plate 3 is integrally formed on the top of the air inlet mesh plate 2. A switching fan structure 4 is provided on the top of the mounting frame 1. A pull-out motor 28 is fixedly installed on one side of the mounting frame 1. A side cover plate 13 is movably installed on one side of the mounting frame 1 below the pull-out motor 28. An oil collection box 14 is fixedly installed at the bottom of one side of the side cover plate 13. A partition sealing plate 15 is fixedly installed in the center of the interior of the mounting frame 1. The interior of the mounting frame 1 is located in the space between the partition sealing plate 15 and the oil collection box 14. A purification filter element 16 is fixedly installed on the side. Inside the mounting frame 1, on the other side of the partition sealing plate 15, a filter plate mounting frame 17 is fixedly installed. A side air guide hood 18 is fixedly installed on one side of the filter plate mounting frame 17. A switch motor 19 is fixedly installed at the upper end of the side air guide hood 18. The switch motor 19 is movably installed inside the side air guide hood 18. A top air guide hood 21 is fixedly installed at the upper end of the filter plate mounting frame 17. Activated carbon filter plates 22 are fixedly installed at both the front and rear ends of the filter plate mounting frame 17. A mesh frame mounting frame 23 is fixedly installed above the front and rear ends of the filter plate mounting frame 17. An oil-separating structure 24 is provided at the lower end of the mesh frame mounting frame 23.

[0030] Please refer to this carefully. Figure 4 The switching fan structure 4 includes a sealing baffle 5, a push-pull toothed plate 6, a sliding plate 7, a fan box 8, an exhaust fan 9, and an exhaust port 10. The sealing baffle 5 and the sliding plate 7 are located on the top of the mounting frame 1. The sealing baffle 5 and the sliding plate 7 are fixedly connected in parallel. The push-pull toothed plate 6 is embedded in the bottom surface of the sealing baffle 5. The fan box 8 is fixedly installed on the upper end of the sliding plate 7. The exhaust fan 9 is rotatably installed inside the fan box 8. The exhaust port 10 is opened on one side of the fan box 8.

[0031] Please refer to this carefully. Figures 1-3 The snap-fit ​​plate 3 is snapped into the front and rear of the sliding plate 7 and is movably connected to it. The air guide plate 11 has an air guide hole 12 inside. The sealing baffle 5 and the sliding plate 7 are both attached to the upper end of the air guide plate 11. The fan box 8 is connected to the interior of the mounting frame 1 through the sliding plate 7 and the air guide hole 12.

[0032] Please refer to this carefully. Figures 1-4 The pull-out motor 28 is located below the sealing baffle 5, and the shaft of the pull-out motor 28 is connected to the push-pull toothed plate 6 through gear meshing.

[0033] Specifically, when the pull-out motor 28 runs, the drive shaft gear rotates, and the gear meshes with the push-pull toothed plate 6, thus pulling the sealing baffle 5 to move left and right, thereby causing the sliding plate 7 to slide left and right within the snap-fit ​​plate 3, switching the left and right positions of the fan box 8.

[0034] Please refer to this carefully. Figure 5 and Figure 6 The front and rear ends of the air guide plate 11 and the partition sealing plate 15 are fitted and connected to the front and rear air inlet mesh plates 2, and the purification filter element 16 and the filter plate mounting frame 17 are both located between the two air inlet mesh plates 2.

[0035] Please refer to this carefully. Figure 5 and Figure 6 The air outlets of the purification filter element 16 and the top air guide hood 21 both face the air guide top plate 11, and the partition sealing plate 15 is fixedly connected to the top of the purification filter element 16.

[0036] Specifically, when the fan box 8 is located on the right side, the internal exhaust fan 9 rotates to generate negative pressure and draw in air from below, so that the outside air passes through the right side of the air intake mesh 2 and enters the mounting frame 1. Then, the air is purified by passing through the purification filter 16, and then passes upward through the air guide hole 12 into the fan box 8. Finally, the air is discharged from the exhaust port 10 on one side of the fan box 8 to achieve air purification.

[0037] Please refer to this carefully. Figures 5-7 The rotating shaft of the switch motor 19 passes through the side air guide shroud 18 and is fixedly connected to the switch plate 20. The side air guide shroud 18 passes through the partition sealing plate 15 and is located on one side of the purification filter element 16.

[0038] Specifically, the operation of the switch motor 19 controls the rotation of the switch plate 20, which causes the switch plate 20 to seal and open the side air guide shroud 18. When the side air guide shroud 18 is opened, the air in the filter plate mounting frame 17 can pass through the side air guide shroud 18 and enter one side of the mounting frame 1 to contact the purification filter element 16.

[0039] Please refer to this carefully. Figure 7 The oil separation structure 24 includes a filter frame 25, an oil separation filter 26, and a guide channel 27. The filter frame 25 is movably installed at the lower end of the mesh frame mounting frame 23, the oil separation filter 26 is fixedly installed on the inner side of the filter frame 25, and the guide channel 27 is fixedly installed below the front end of the filter frame 25.

[0040] Please refer to this carefully. Figures 5-7 The guide channel 27 is located below the oil separator filter 26. One end of the guide channel 27 passes through one side of the mounting frame 1 and is inserted into the oil collection box 14. The two oil separator filters 26 are located in front of and behind the two activated carbon filter plates 22, respectively.

[0041] Specifically, when the fan box 8 is located on the left side, the negative pressure generated by the exhaust fan 9 causes external air to pass through the left side of the air intake mesh 2 and enter the mounting frame 1. Then, the air first passes through the oil separator 26, and the metal mesh structure of the oil separator 26 filters the grease in the air. Then, the air passes through the activated carbon filter 22 to filter the particulate matter in the air. Finally, the air enters the center of the filter plate mounting frame 17, and enters the fan box 8 from the top air guide hood 21 through the air guide hole 12. Finally, it is discharged from the exhaust port 10 on one side of the fan box 8 to achieve air fume purification.

[0042] Please refer to this carefully. Figure 6 A support bracket 29 is fixedly installed at the lower end of the mounting frame 1. The support bracket 29 is arranged parallel to the oil collection box 14. A switch grille 30 is rotatably installed on one side of the air intake mesh plate 2 adjacent to the mounting frame 1.

[0043] Specifically, the grease on the oil filter screen 26 drips down into the guide groove 27 and flows into the oil collection box 14 for collection. The switch grille 30 seals one side of the air intake screen 2 by rotating the switch.

[0044] It should be noted that this invention relates to a breathable structure in an air purifier for oil fume pollution. During use, when the air is free of oil fumes, the fan box 8, located on the right, uses the purification filter element 16 to filter the air for particulate matter. When the air contains oil fumes, the fan box 8, located on the left, first uses the grease filter 26 to filter the grease, and then uses the activated carbon filter plate 22 to adsorb and filter smoke particles and odors, effectively filtering the oil fumes in the air. This also prevents the purification filter element 16 from failing to filter oil fumes adequately and from excessively rapid consumption of consumables. Furthermore, it addresses the issue of varying oil fume content... When the height is too high, the fan box 8 is located on the right side, and the switch grille 30 on the right side of the air intake mesh 2 is closed, sealing the right side of the air intake mesh 2. The side air guide shroud 18 opens the switch plate 20, so air enters from the left side of the air intake mesh 2, is filtered by the oil separator filter 26 and the activated carbon filter plate 22, and then passes through the side air guide shroud 18 into the right side of the mounting frame 1. It is then filtered again by the purification filter element 16 and discharged, achieving three-layer filtration. Opening the side cover 13 allows the filter plate mounting frame 17 to be removed, enabling quick replacement of the activated carbon filter plate 22 and the oil separator filter 26.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
