AI Technical Summary
Traditional smoke extraction devices suffer from energy waste and installation compatibility issues in multi-burner designs. Integrated oil fume purification units operate at fixed maximum power, resulting in high energy consumption. Furthermore, the air valves cannot be installed inside the smoke extraction hood, limiting the applicability of the devices.
A smoke exhaust device for gas stoves was designed, which adopts a variable frequency oil fume purification unit and a wind valve linkage control. The power is adjusted according to the number of main units of the stove. The wind valve can be installed inside the fume hood or between the flue pipes to achieve precise and directional smoke exhaust.
Variable frequency control enables energy-saving smoke extraction, avoids energy waste, improves the adaptability of the device, prevents oil fume cross-contamination and backflow, and enhances energy utilization efficiency.

Abstract
Claims
1. A smoke exhaust device for a gas stove, disposed above a gas stove unit (1), the gas stove unit (1) comprising a plurality of stove bodies arranged side by side, characterized in that, The exhaust device includes a fume hood (2), a flue pipe (4) connected to the fume hood (2) at one end, and a variable frequency oil fume purification unit (5) connected to the other end of the flue pipe (4). The fume hood (2) is provided with several installation ports connected to the flue pipe (4). Each installation port is provided with a wind valve (3) corresponding to the main body of the stove. The main body of the stove and the wind valve (3) are electrically connected to the variable frequency oil fume purification unit (5). The wind valve (3) is used to open when the corresponding main body of the stove is working. The speed of the variable frequency oil fume purification unit (5) corresponds to the number of main bodies of the stove working.
2. The smoke evacuation device of claim 1, wherein, The variable frequency fume purification unit (5) includes a variable frequency fan.
3. The smoke evacuation device of claim 1, wherein, The air valve (3) includes a frame (32) disposed in the installation port, a plurality of blades (33) disposed in the frame (32) rotating via a rotating shaft connector (34), and a drive unit for driving the plurality of blades (33) to rotate to close or open the frame (32) opening.
4. A smoke extraction device according to claim 3, characterised in that The drive unit includes an electrical box (31) on the fume hood (2), a telescopic device (35) inside the electrical box (31), a connecting rod (38) movably disposed within the wall thickness of the side wall of the frame (32), and a pull rope (37) connecting the telescopic device (35) and the connecting rod (38). The connecting rod (38) is axially connected to several sets of connecting plates (310), and each connecting plate (310) is axially connected to the rotating shaft connector (34) of the corresponding blade (33). The end of the connecting rod (38) away from the pull rope (37) is connected to the inner wall of the frame (32) through an elastic element (39). The connecting rod (38) is driven to move by the pull rope (37) pulled by the telescopic device (35), thereby controlling the opening and closing of the blade (33) by the linkage of the connecting plate (310) and the elastic element (39).
5. A smoke extraction device according to claim 4, characterised in that The rotating shaft connector (34) includes a spring pin detachably disposed at one end of the outer wall of the blade (33) and a rotating shaft seat detachably disposed on the blade (33) and relative to one end of the spring pin. The connecting plate (310) is disposed at the rotating shaft end of the rotating shaft seat.
6. The smoke evacuation device of claim 4, wherein, The electrical box (31) is provided with a pulley seat (36) for guiding the pull rope (37).
7. The smoke evacuation device of claim 4, wherein, The electrical box (31) is located on the outer wall of the fume hood (2), and its top is detachably covered.
