From an upward perspective, almost half of the area of ​​this type of air intake is occupied by the mesh, with a small contact area with the air and low efficiency in extracting oil fumes. In addition, all the mesh holes are completely open, and when suction is performed, the incoming air is scattered and the flow is unstable, which also affects the efficiency of extracting oil fumes.

[0006] As an improvement, the three layers of corrugated plates are three layers in the width direction of the rectangular suction pipe.

[0007] As an improvement, the bottom ends of the two side wave plates are flush.

[0008] As an improvement, the wave plate is fixedly connected to the rectangular air suction pipe.

[0009] The advantages of the present invention compared with the prior art are: almost the entire area of ​​the rectangular suction pipe is used for air intake, the corrugated opening and the triangular opening are designed in layers in the vertical direction to further increase the contact area with the air, and the intervals between the corrugated plates are conducive to the flow diversion effect. The suction port of the range hood has a high efficiency in absorbing oil fumes. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In addition, if the terms "first", "second", "third", etc. appear, they are only used to distinguish the description and cannot be understood as indicating or implying relative importance. If the terms "horizontal", "vertical", "overhanging", etc. appear, it does not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and it does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of the embodiments of the present invention, if the terms "multiple" or "several" appear, they represent at least two.

[0020] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] This embodiment combines the attached Figures 1 to 3 , an air intake port of a range hood is described in detail.

[0022] The present embodiment provides an air suction port of a range hood, comprising a range hood body 1, characterized in that a fixed air suction port is provided at the bottom of the range hood body 1, the air suction port comprises a rectangular air suction pipe 2, three layers of corrugated plates are provided in the rectangular air suction pipe 2, namely a middle corrugated plate 3 and two side corrugated plates 4, the bottom end of the middle corrugated plate 3 is lower than the side corrugated plate 4, the middle corrugated plate 3 and the side corrugated plate 4 have the same corrugation and form a corrugated opening 6, the side corrugated plate 4 and the rectangular air suction pipe 2 form a continuous triangular opening 5.

[0023] The three-layer wave plate is three layers in the width direction of the rectangular suction pipe 2.

[0024] The bottom ends of the two side wave plates 4 are flush.

[0025] The wave plate is fixedly connected to the rectangular air suction pipe 2 .

[0026] In specific implementation, the range hood with this air suction port is a top-suction range hood. When in use, the oil smoke can enter the rectangular suction pipe 2 from the corrugated port 6 and the triangular port 5 and be sucked away. The corrugated port 6 and the triangular port 5 are layered in the vertical direction to increase the contact area with the air, which is more conducive to sucking away the oil smoke. The spacing between the corrugated plates is conducive to the diversion effect.
