Description

Technical Field

[0001] This utility model relates to the field of exhaust hood technology, specifically a kitchen exhaust hood. Background Technology

[0002] Cooking in the kitchen generates a large amount of fumes, which contain grease, impurities, and harmful gases. If these fumes are not removed promptly, they can seriously affect the kitchen environment and human health. As an important component of the kitchen ventilation system, the kitchen exhaust hood's primary function is to collect and remove these fumes to maintain fresh air in the kitchen.

[0003] Traditional kitchen exhaust hoods typically use a funnel-shaped filter structure to filter cooking fumes, effectively removing grease and impurities. However, after a period of use, grease buildup in the filter holes can obstruct the passage of fumes, necessitating cleaning. Cleaning and replacing the filters in traditional exhaust hoods is difficult, requiring significant time and effort. Furthermore, due to the flawed filter design and limited operating space, thorough cleaning of the filter's interior is challenging, impacting filtration efficiency and kitchen hygiene. Therefore, a new type of kitchen exhaust hood is needed to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a kitchen exhaust hood, including an exhaust hood body 1. A filter mechanism 3 is provided below the exhaust hood body 1. The filter mechanism 3 includes a first filter screen 4 and a second filter screen 5. The first filter screen 4 is rotatably disposed in the internal area of ​​the exhaust hood body 1, and the second filter screen 5 is disposed on one side of the first filter screen 4. A locking assembly 7 is provided in the internal area of ​​the first filter screen 4. The filter mechanism 3 is the main part for filtering oil fumes, and its purpose is to remove grease and impurities from the oil fumes, reduce environmental pollution and damage to exhaust pipes and fans.

[0022] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the locking assembly 7 includes an elastic rubber ball 15, one end of which is fixed with a telescopic slide rod 14. A return spring 17 is sleeved on the surface of the telescopic slide rod 14. A positioning frame 6 is fixed above the second filter shell 5. The elastic rubber ball 15 is attached to the inner wall of the positioning frame 6. A flipping block 13 is fixed to the lower end of the first filter shell 4. A flipping support 12 is fixed below the second filter shell 5. The flipping block 13 is rotatably connected to the flipping support 12. A [missing information - likely a device or component] is fixed to the inner wall of the first filter shell 4. A lifting sleeve 16 is fixedly fitted around the fixed support plate 18 and the telescopic slide rod 14. The telescopic slide rod 14 is slidably connected to the fixed support plate 18. The locking assembly 7 is used to lock and unlock the first filter screen shell 4 and the second filter screen shell 5, and to control the flipping state of the first filter screen shell 4. The elastic rubber ball 15 is attached to the inner wall of the positioning frame 6 to lock the first filter screen shell 4 and restrict its flipping. When it is necessary to flip the first filter screen shell 4, the elastic rubber ball 15 leaves the inner ring wall of the positioning frame 6 and releases the lock.

[0023] Further as Figure 3 As shown, it is worth noting that a sealing gasket is fixed on the upper end face of the flip support 12, one end of the return spring 17 is fixed on the lower end face of the lifting sleeve 16, and the other end of the return spring 17 is fixed on the upper end face of the fixed support plate 18. The first filter screen 4 is an important component of the filter mechanism 3, participating in the initial filtration of oil fumes. At the same time, it can be rotatably installed inside the exhaust hood body 1, and can be flipped to facilitate internal cleaning.

[0024] Further as Figure 5 As shown, it is worth noting that a mounting bracket 9 is fixed on the inner top wall of the main body 1 of the smoke hood. An assembly port 10 is opened at the lower end of the mounting bracket 9. A torsion ring groove 11 communicating with the assembly port 10 is opened inside the mounting bracket 9. A positioning slider 8 is fixed on the upper end face of the positioning frame 6. The assembly port 10 and the torsion ring groove 11 are both adapted to the positioning slider 8. The positioning slider 8 is fixed on the upper end face of the positioning frame 6 and is adapted to the assembly port 10 and the torsion ring groove 11 of the mounting bracket 9. The filter mechanism 3 can be rotated and disassembled by rotating along the torsion ring groove 11 and taking it out from the assembly port 10.

[0025] Further as Figure 1 As shown, it is worth noting that the lower end of the flip support 12 is threadedly connected to an oil collection box 19, and the upper end of the exhaust hood body 1 is provided with an exhaust port 2.

[0026] This solution has the following working process: When in use, the oil fumes enter the exhaust port 2 after being filtered by the first filter shell 4 and the second filter shell 5. They are then led out of the kitchen by the fan in the exhaust port 2. When cleaning the first filter shell 4 and the second filter shell 5, first rotate the flip support 12 below the first filter shell 4 and the second filter shell 5. This will drive the positioning frame 6 to rotate along the torsion ring groove 11 of the mounting support 9 via the positioning slider 8 until the positioning slider 8 rotates to the assembly port 10 that communicates with the torsion ring groove 11. At this time, the positioning slider 8 can be removed along the assembly port 10 of the mounting support 9 to disassemble the filter mechanism 3. The positioning slider 8 and the assembly port 10 are built between the positioning frame 6 and the mounting support 9. This makes the rotation disassembly and assembly method convenient for the filter mechanism 3 to be quickly and smoothly disassembled and assembled on the exhaust hood body 1.

[0027] When brushing the inside of the first filter screen 4 and the second filter screen 5, press down the telescopic slide bar 14, which drives the lifting sleeve plate 16 to press down, causing the return spring 17 to deform. At this time, the elastic ball 15 leaves the inner ring wall of the positioning frame 6 and releases the flipping restriction of the first filter screen 4. The first filter screen 4 flips outward on the flipping support 12 through the flipping block 13. This can expand the brushing operation space between the first filter screen 4 and the second filter screen 5, thereby providing convenient conditions for cleaning the inside of the first filter screen 4 and the second filter screen 5.
