Abstract: A fume collecting assembly, a range hood, a side suction range hood, a range hood for two-sided fume collection and central air intake, a range hood with partition, and a central fume purification device are provided. The fume collecting assembly includes a fume collecting panel having curved recessed portion and an air deflector, which has curved protruding portion and is connected to the fume collecting panel, and the curved protruding portion is opposite the curved recessed portion, forming first air inlet and second air inlet spaced apart. The fume collecting panel includes a fume collecting port for discharging fumes into a duct of range hood. The first air inlet and the second air inlet both communicate with the fume collecting port. The range hood, the side suction range hood, the range hood for two-sided fume collection and central air intake, and the range hood with partition include the fume collecting assembly.

Abstract: A burner comprises a stove core, a fire cover, and a stove plate and stove end. A plurality of stove core fire outlet hole lugs are arranged on the stove core, stove core fire outlet holes are arranged on each of the stove core fire outlet hole lugs, and a stove core air inlet channel is arranged between adjacent stove core fire outlet hole lugs. A plurality of fire cover fire outlet hole lugs are arranged on the fire cover, fire cover fire outlet holes are arranged on each of the fire cover fire outlet hole lugs, a fire cover air inlet channel is arranged between adjacent fire cover fire outlet hole lugs, and the direction of fire outlet position of the stove core fire outlet hole faces the channel opening of the corresponding fire cover air inlet channel. With the flames of the stove core and the flames of the fire cover being crossed by the alternating arrangement of the fire outlet holes, the air contact area is enlarged such that the heat efficiency is improved.
