[0002] The existing technology, Chinese patent 201720261326.9, describes an improved lighting side-suction range hood, including a casing, a fan, a drive mechanism, an oil cup, a front panel, a light, and a main control board. The front panel of the casing has an oil fume collection chamber, and the rear panel of the oil fume collection chamber has oil fume guiding holes. The upper part of the front panel of the oil fume collection chamber has a through hole opposite to the main control board. The front panel includes an upper glass plate, a middle glass guide plate, and a lower glass plate. The main control board is located in a control cavity formed by the top of the oil fume collection chamber and the top plate of the casing. It also includes a lampshade with a front opening, and the light is fixed inside the lampshade. The front opening of the lampshade is fixedly connected to the middle glass guide plate. In a static state, the lampshade is located inside the oil fume collection chamber. In use, the middle glass guide plate forms an acute angle with the horizontal plane at the lower front of the casing, and the lampshade faces downwards. The problem is that during operation, the middle glass plate flips, creating a negative pressure zone below it, which still poses a risk of smoke overflow. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
