Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-4, an oil smoke purifying range hood comprises a range hood 1 with an oil smoke purifying function, an exhaust pipe 2 is arranged at the upper end of the range hood 1, an air pump for exhausting air is arranged at one end of the exhaust pipe 2, and a collecting device 4 convenient for collecting oil stains is arranged at the lower end of the inner wall of the range hood 1;

the collecting device 4 comprises a V-shaped filter screen 3 and a collecting box assembly positioned below the extending section of the V-shaped filter screen 3, the V-shaped opening direction of the V-shaped filter screen 3 faces downwards, and the collecting box assembly is arranged at the bottom of the range hood 1;

the collecting box assembly comprises a collecting box 401, the lower end of the collecting box 401 is provided with a sewage discharge hole, the sewage discharge hole is sealed through a sealing plug, the upper end of the collecting box 401 is fixed with a plurality of groups of fixing frames 403, the upper end of the fixing frames 403 is fixed at the lower end of the range hood 1 through bolts, and the outer wall of the collecting box 401 is wrapped with anti-collision rubber 402; in practical application, because exhaust pipe 2 sets up in range hood 1 intermediate position to the oil smoke can concentrate and inhale away from range hood 1 intermediate position, will collect box 401 and set up in range hood 1 lower extreme edge, thereby reduce the production of collecting box 401 lower extreme oil smoke, V type filter screen 3 passes through the V type setting simultaneously, thereby will drip the direction oil smoke 1 both sides of range hood, avoids dripping to drop from the centre.

Further, the cross section of the collecting box 401 is U-shaped, and the size of the U-shaped opening of the collecting box 401 is larger than the wall thickness of the shell of the range hood 1; in practical application, the U-shaped opening of the collecting box 401 is larger than the wall thickness of the housing of the range hood 1, so that oil drops on the outer wall of the housing of the range hood 1 can drop into the collecting box 401.
