[0002] This utility model relates to the technical field of barbecue restaurants, where the emission of oil fumes directly affects the dining experience and environmental hygiene of customers. Traditional tabletop exhaust ducts often lack sufficient smoke extraction capacity when dealing with large or specially shaped barbecue grills, easily leading to the escape of oil fumes and pollution of indoor air. The emergence of the extended smoke collection cover effectively addresses this problem. By combining a rectangular tube sleeve with a variety of lower cover plates, this device can flexibly adapt to rectangular and round barbecue grills, significantly improving the smoke extraction effect and effectively reducing the escape of oil fumes from the perimeter of the duct. At the same time, its modular design facilitates installation and disassembly, making daily use and cleaning maintenance convenient, greatly enhancing the stability and service life of the equipment.

[0003] This device not only improves smoke extraction efficiency, providing customers with a fresh and comfortable dining environment, but also plays a significant role in energy conservation and emission reduction. Through a more efficient smoke collection method, restaurants can reduce the wind power required for the exhaust ducts, lower equipment energy consumption, and reduce oil fume pollution.

[0004] Existing technical solutions, which rely solely on the flue opening for smoke extraction, suffer from insufficient smoke extraction capacity when using large-sized barbecue grills, resulting in fumes escaping from the flue's perimeter. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an extended smoke collection cover for a desktop exhaust duct, which solves the technical problem that existing solutions, which rely solely on the exhaust duct opening for smoke extraction, have insufficient smoke extraction capacity when using large-sized barbecue grills, resulting in fumes escaping from all sides of the duct.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extended smoke collection cover for a desktop exhaust duct, comprising a sleeve and a lower cover plate. The sleeve is a rectangular sleeve with an extended insertion port on its side wall and a smoke inlet at its lower end. The lower cover plate is fixedly connected to the lower wall of the sleeve, and its upper end is sealed to the lower end of the sleeve. The sleeve is inserted into a rectangular exhaust duct, and smoke is collected through the lower cover plate.

[0007] Preferably, the lower cover plate is a rectangular platform, the upper end of the lower cover plate is a rectangle with the same cross-section as the lower wall of the sleeve, the lower end of the lower cover plate is a rectangle, and the cross-section of the lower cover plate is an isosceles trapezoid that is narrower at the top and wider at the bottom, which is suitable for rectangular barbecue grills and provides better smoke extraction capability for rectangular barbecue grills.

[0008] Preferably, the lower cover plate is further configured as a platform with a rectangular upper surface and a circular lower surface. The vertical cross-section of the lower cover plate is an isosceles trapezoid that is narrower at the top and wider at the bottom, which is suitable for round barbecue grills and provides better smoke extraction capability for round barbecue grills.

[0009] Preferably, the side wall of the lower cover plate is provided with a flue groove, which helps to reliably install the smoke collection cover plate for flues with a short distance after the bend in the oil exhaust flue.

[0010] Preferably, an extension tube is slidably installed inside the sleeve. The extension tube is a rectangular tube, and a push button is fixedly installed on the upper wall of the extension tube. This is an optional component that helps to improve the stability after installation, making it less likely for the sleeve to slip off after touching the lower cover plate, thus providing a more stable installation effect.

[0011] Preferably, the lower cover plate is provided with a smoke extraction hole, and an auxiliary lighting diode is fixedly installed inside the lower cover plate. The smoke extraction hole helps to draw in more oil fumes when the exhaust duct forms a negative pressure, preventing the oil fumes from escaping. The auxiliary lighting diode enhances the dining experience for customers.

[0012] Beneficial effects

[0013] This utility model provides an extended smoke collection cover for a desktop exhaust duct. Through optimized design, the smoke collection cover significantly enhances the smoke extraction capacity of the desktop exhaust duct, especially when using large-sized or specially shaped barbecue grills.
