[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the gravity direction. In addition, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] See Figures 1 to 5 , an oil fume suction machine, comprising a box body 1 and a smoke collecting hood 2 arranged at the bottom of the box body 1. The fan system (not shown) serving as the power of the oil fume suction machine can be arranged inside the box body 1, or another box body communicating with the box body 1 can be provided for arranging the fan system.

[0030] The width of the box body 1 in the left-right direction is smaller than that of the smoke collecting hood 2. Therefore, a set of back panel assemblies 3 are respectively arranged on the left and right sides of the box body 1, and the back panel assemblies 3 correspond to the rear ends of the box body 1 and the smoke collecting hood 2. The height of the back panel assemblies 3 is approximately equal to that of the box body 1, and the total width of the two sets of back panel assemblies 3 and the box body 1 is approximately equal to the width of the smoke collecting hood 2. The two sets of back panel assemblies 3 have the same structure and are symmetrically arranged.

[0031] The back panel assemblies 3 are respectively installed on the box body 1 and the smoke collecting hood 2. Specifically, each set of back panel assemblies 3 includes a back panel glass 31, a back plate 32, and a gasket 33. The back panel glass 31 is arranged on the back plate 32, and most of the back plate 32 is located on the back surface of the back panel glass 31 (i.e., the surface facing the rear and away from the user in the installed state), so as to be installed on the box body 1 and the smoke collecting hood 2 through the back plate 32, and the back panel glass 31 is protected by arranging the back plate 32.

[0032] The box body 1 includes side plates 11 near the left and right sides. The rear plate 32 includes a plate body 321 whose size and shape match those of the back panel glass 31. The plate body 321 is located on the back side of the back panel glass 31. The back panel glass 31 is in close contact with the side plates 11, while the plate body 321 can slightly exceed the side plates 11 inward to form a mounting portion 322 corresponding to the side plates 11 as described below. That is, for the right back panel assembly 3, the left end of its rear plate 32 can be located on the left side of the right side plate 11, and for the left back panel assembly 3, the right end of its rear plate 32 can be located on the right side of the left side plate 11. A mounting portion 322 is formed at the top of the plate body 321. The mounting portion 322 is provided at a position corresponding to the corresponding side plate 11 of the plate body 321 and extends forward from the position of the plate body 321. Thus, the mounting portion 322 can cooperate with the side plate 11. During installation, the mounting portion 322 is located at the top of the side plate 11, and the two can be fixed by screws. The rear plate 32 further includes folding ears 323, which are formed by bending the plate body 321 forward from the side close to the corresponding side plate 11. The folding ears 323 can have one, two or more. In this embodiment, there are two arranged at intervals up and down. The folding ears 323 are in close contact with the side surface of the back panel glass 31 to prevent stress concentration at the corners of the back panel glass 31.

[0033] See Figure 3 , Figures 6 to 9 , a mounting groove 21 is formed at the rear end of the top of the smoke collecting hood 2. The mounting groove 21 is formed by recessing downward from the top surface of the smoke collecting hood 2. The mounting groove 21 extends in the left-right direction and is used to insert the back panel glass 31. The gasket 33 of the back panel assembly 3 is placed in the mounting groove 21 and supports the bottom of the back panel glass 31. The gasket 33 has a certain elasticity to ensure reliable installation of the back panel glass 31. Through the setting of the mounting groove 21, the overall appearance of the machine can be more integrated, and there will be no light leakage phenomenon caused by the slight inclination or gap of the back panel assembly 3.

[0034] The rear plate 32 further includes a convex portion 324 extending downward from the bottom of the plate body 321. The convex portion 324 is located below the top surface of the smoke collecting hood 2 and behind the mounting groove 21. A screw bushing assembly 22 is provided at the rear of the smoke collecting hood 2. A support groove 3241 is formed by recessing the bottom surface of the convex portion 324 upward. The convex portion 324 supports on the screw bushing assembly 22. The support groove 3241 is semicircular, so that it can cooperate with the screw bushing assembly 22. The screw bushing assembly 22 includes a screw 221 and a bushing 222 provided on the outer periphery of the rod portion of the screw 221. The peripheral wall of the support groove 3241 wraps around the outer periphery of its bushing 222. The screw bushing assembly 22 can have two groups and is arranged at intervals left and right.

[0035] Thus, through the cooperation of the convex portion 324 and the screw bushing assembly 22, the offset of the back panel assembly 3 in the left-right direction can be restricted. The stress in the horizontal direction is concentrated on the two folding ears 323 of the rear plate 32, and a certain distance should be maintained between the side of the back panel glass 31 away from the side plate 11 and the corresponding side of the smoke collecting hood 2. The cooperation between the mounting portion 322 and the side plate 11 can restrict the offset of the back panel assembly 3 in the vertical direction and the offset in the rotational direction.
