[0004] The utility model is realized as follows: a range hood with multiple smoking holes, which is special in that it includes a housing, a wind cabinet and a glass smoke guide plate.

[0005] The housing includes a front opening and a negative pressure cavity provided on the front wall.

[0006] The negative pressure chamber has a front oblique opening, the end surface of the front oblique opening forms an acute angle with the horizontal plane in front, and a top fume suction hole group is provided at the rear of the top plate of the negative pressure chamber;

[0007] The glass smoke guide plate is equipped with horizontal oil smoke suction holes;

[0008] The upper end of the glass smoke guide plate and the front wall plate of the casing above the front opening of the casing form a middle horizontal oil smoke suction hole.

[0009] The special feature of the range hood with multiple smoking holes is that it also includes a top glass plate, which is arranged on the front wall plate above the front opening.

[0010] The special feature of the range hood with multiple smoking holes is that there is a height difference between the upper end of the glass smoke guide plate and the lower end of the top glass plate.

[0011] The special feature of the range hood with multiple smoking holes is that the angle between the glass smoke guide plate and the front horizontal plane is greater than the angle between the end surface of the front oblique opening and the front horizontal plane.

[0012] The special feature of the range hood with multiple smoking holes is that an acute angle is formed between the top plate of the negative pressure chamber and the horizontal plane in front.

[0013] The utility model discloses a range hood with multiple smoke suction holes. The top smoke suction hole group, the middle horizontal smoke suction hole and the horizontal smoke suction hole are arranged to realize multi-level smoke suction. The arrangement of the negative pressure cavity increases the smoke suction area and effectively prevents smoke overflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0020] like Figure 1 、 Figure 2 As shown, a range hood with multiple smoking holes includes a housing 1, a wind cabinet 2 and a glass smoke guide plate 3.

[0021] The housing 1 includes a front opening 11 and a negative pressure chamber 12 provided on the front wall.

[0022] The negative pressure chamber 12 has a front oblique opening, the end surface of which forms an acute angle α with the horizontal plane in front. A top fume intake hole group 121 is provided at the rear of the top plate of the negative pressure chamber 12. There are two top fume intake hole groups 121, which are arranged on the left and right sides.

[0023] The glass smoke guide plate 3 is provided with a transverse oil smoke suction hole 31, which is provided in the middle of the height direction of the glass smoke guide plate 3 and has a length direction along the left-right direction;

[0024] The lower end of the glass smoke guide plate is fixed to the front wall of the housing below the front opening, and its two sides are bonded to the side walls of the housing. The upper end of the glass smoke guide plate 3 and the front wall of the housing 1 above the front opening of the housing 1 form a central horizontal oil smoke intake hole 4. The upper end of the glass smoke guide plate 3 and the front wall of the housing at the top of the front opening serve to separate oil smoke.

[0025] As a further improvement of the present invention, it further comprises a top glass plate 5 , which is arranged on the front wall plate at the upper part of the front opening.

[0026] As a further improvement of the present invention, there is a height difference between the upper end of the glass smoke guide plate 3 and the lower end of the top glass plate 5. In other words, there is a height difference between the upper end of the glass smoke guide plate 3 and the front wall of the housing at the front opening.

[0027] There is an acute angle β between the top plate of the negative pressure chamber 12 and the horizontal plane in front.

[0028] The angle γ between the glass smoke guide plate and the front horizontal plane is greater than the angle α between the end surface of the front oblique opening and the front horizontal plane.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
