Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a mounting structure of a smoke baffle of a range hood and the range hood. Background Art

[0002] In order to improve the oil fume extraction effect, existing range hoods, especially close-suction range hoods, are provided with a smoke baffle at the smoke inlet. The installation structure of the smoke baffle is disclosed in the Chinese invention patent application "Smoke baffle drive system, smoke baffle drive method, range hood, and storage medium" with application number 202310804283.4 and application publication number CN116734301A. The smoke baffle drive system is connected to the smoke baffle, and includes a motor; a transmission mechanism is connected between the motor and the smoke baffle, and can convert the rotational motion of the motor into a swinging motion of driving the smoke baffle; a hydraulic system is connected to the transmission mechanism, and is used to provide resistance to the transmission mechanism to adjust the driving speed of the smoke baffle.

[0003] Another example is the solution disclosed in the Chinese utility model patent "Ranoid Hood" with patent number 202123305470.3 and authorization announcement number CN216744515U, which includes: a smoke hood, a push rod mechanism, a flap, a first screw and anti-collision blockage. The flap is hinged to the smoke hood, and the push rod mechanism is connected to the flap to drive the flap to swing relative to the smoke hood. A countersunk hole extending from the outside to the inside is provided on the smoke hood. After the first screw passes through the countersunk hole, it is connected to the push rod mechanism on the inside of the smoke hood. Along the depth direction of the countersunk hole, the top surface of the first screw is lower than the opening end surface of the countersunk hole. A certain gap is left between the opening of the countersunk hole and the top surface of the first screw, and the gap is used to accommodate anti-collision blockage.

[0004] Existing smoke baffles are mostly connected to the output end of the driving mechanism through fasteners such as screws, but due to problems with the processing technology, there will be sharp burrs on the fasteners. When the user cleans the range hood, the user's fingers are easily scratched by the burrs on the fasteners, which poses a safety problem. Utility Model Content
