[0002] Existing range hood smoke hoods generally use top plates, back plates, left and right side plates, front cover plates and other parts to fix by screws, rivets, welding and other methods, and enclose a closed box structure. Specifically, the Chinese utility model patent "A Range Hood" with patent number 202122574231.1 and authorization announcement number CN216790286U includes a smoke hood and a fan frame arranged above the smoke hood, and a fan system is arranged in the fan frame. The smoke hood includes a top plate and a left side plate and a right side plate arranged at intervals on the left and right. The top plate is connected between the tops of the left and right plates, and the lower end of the fan frame passes through the top plate. The range hood also includes a guide assembly, which includes two first guide plates, one of which extends between the lower left end of the fan frame and the left plate, and the other first guide plate extends between the lower right end of the fan frame and the right plate.

[0003] The existing smoke hood has a large number of parts, a complicated assembly process, and low assembly efficiency.
