The lining plate 1 is provided with a through hole 11. The glass panel 2 is fixed to the outer side of the lining plate 1. The front end of the switch display box 3 is inserted into the through hole 11 and abuts against the glass panel 2. The side wall of the switch display box 3 is connected to the inner side of the lining plate 1. The sealing assembly 4 is connected between the lining plate 1 and the side wall of the switch display box 3. The fastening structure 5 connects the switch display box 3 and the lining plate 1 to tightly fit the sealing assembly 4 to the inner side of the lining plate 1 and the glass panel 2. The glass panel 2 of the present application is fixed to the outer side of the lining plate 1 by glass glue. The sealing performance between the lining plate 1 and the switch display box 3 is increased by arranging the sealing assembly 4 between the lining plate 1 and the switch display box 3. The switch display box 3 and the lining plate 1 are fastened by the fastening structure 5, so that the display screen 33 on the switch display box 3 can be tightly fitted on the glass panel 2. The present application can not only form a sealed barrier between the lining plate 1 and the switch display box 3, achieving oil-proof, smoke-proof and waterproof effects; it can also make the display screen 33 close to the glass panel 2, solving the problem that the box body 31 of the switch display box 3 cannot be close to the glass due to uneven deformation, which ultimately leads to unclear display. It should be noted that the "front end" of the present application is defined based on the front and back of the range hood, and the front end of the switch display box 3 is the display screen 33, which is in contact with the glass panel 2, that is, the front end of the switch display box 3 is inserted into the through hole 11 and abuts against the glass panel 2.

[0046] In a preferred embodiment of the present invention, Figure 1-6The switch display box 3 shown is provided with a mounting groove 30 on one side close to the lining plate 1, and a first flange 12 is provided on the outer periphery of the through hole 11, the first flange 12 is inserted into the mounting groove 30, and the sealing assembly 4 is connected between the first flange 12 and the mounting groove 30. The sealing ring 41 of the present application is interference-fitted with the mounting groove 30, and the sealing assembly 4 is arranged at the mounting groove 30 and is in close contact with the first flange 12, which can not only realize the assembly of the switch display box 3, the sealing assembly 4 and the lining plate 1, but also play the role of the first layer of sealing between the switch display box 3 and the lining plate 1, and can effectively increase the sealing performance of the lining plate 1 and the switch display box 3.

[0047] In a preferred embodiment of the present invention, Figure 1-6 The sealing assembly 4 shown includes a sealing ring 41, which is inserted into the installation groove 30. A side of the sealing ring 41 close to the first flange 12 is provided with a limiting groove 411 corresponding to the first flange 12. The first flange 12 is inserted into the limiting groove 411, and the first flange 12 and the limiting groove 411 are interference-fitted. In this way, after the first flange 12 is inserted into the limiting groove 411, the first flange 12 is tightly fitted with the sealing ring 41, thereby achieving sealing between the switch display box 3 and the lining plate 1.

[0048] In a preferred embodiment of the present invention, Figure 1-6 The limiting groove 411 shown includes an inner wall 4111 and an outer wall 4112 located outside the inner wall 4111, and the height of the outer wall 4112 is less than the height of the inner wall 4111. Since the height of the outer wall 4112 is less than the height of the inner wall 4111, when the fastening structure 5 fastens the switch display box 3 and the lining plate 1, the sealing ring 41 is pressed downward, so that the inner wall 4111 elastically abuts and fits tightly on the glass panel 2, so that the sealing ring 41 forms a second layer of sealing.

[0049] In a preferred embodiment of the present invention, Figure 1-6 The free end of the outer side wall 4112 is bent outward 230 to form a second flange 412, and then a channel for the second flange 412 to pass through is formed between the mounting groove 30 and the lining plate 1, and the second flange 412 passes through the channel and extends to the outside of the mounting groove 30. When the fastening structure 5 fastens the switch display box 3 and the lining plate 1, the sealing ring 41 is pressed downward, and the second flange 412 is pressed on the lining plate 1 to form a third layer of sealing.

[0050] Preferably, a guide slope inclined from outside to inside is provided on one side of the outer wall 4112 close to the notch to guide the first flange 12 to facilitate the first flange 12 to be inserted into the limiting groove 411 .

[0051] In a preferred embodiment of the present invention, Figure 1-6As shown, the outer side of the lining plate 1 is connected to a glass panel 2, and the switch glass assembly also includes a fastening structure 5, which connects the switch display box 3 and the lining plate 1 and is used to tightly fit the sealing assembly 4 to the inner side surfaces of the lining plate 1 and the glass panel 2.

[0052] In a preferred embodiment of the present invention, Figure 1-6 The fastening structure 5 shown includes a reinforcing bracket 51 and two bases 52. The reinforcing bracket 51 is in a "J" shape. The reinforcing bracket 51 is sleeved on the side of the switch display box 3 away from the lining plate 1. The two bases 52 are symmetrically distributed on both sides of the switch display box 3. The two bases 52 are detachably connected to the reinforcing bracket 51. Specifically, as Figure 1-4 The base 52 shown is bolted or welded to the lining plate 1, and the reinforcing bracket 51 is sleeved on the top of the switch display box 3 and bolted to the base 52 located therebelow, so as to compress the switch display box 3 and the lining plate 1, improve the sealing performance of the sealing ring 41, and achieve the effects of oil-proof, smoke-proof and waterproof.

[0053] In a preferred embodiment of the present invention, Figure 1-4 The reinforcing bracket 51 shown has a clearance fit with the base 52, wherein when the reinforcing bracket 51 and each base 52 are fastened, the sealing assembly 4 fits tightly against the inner side of the glass panel 2 and the lining plate 1. It cannot be seen from the figure that there is a clearance fit between the reinforcing bracket 51 and the base 52. The purpose of this design is that when the reinforcing bracket 51 and each base 52 are fastened with screws, the reinforcing bracket 51 can generate downward pressure on the box body 31 and the sealing ring 41 thereunder, which can not only make the second flange 412 of the sealing ring 41 fit tightly against the lining plate 1, thereby improving the sealing performance of the sealing ring 41 and the lining plate 1; it can also make the display screen 33 fit tightly against the glass panel 2, and ensure that the display screen 33 can fit tightly against the glass panel 2, thereby improving the clarity and sensitivity of the switch glass assembly.

[0054] Preferably, the height of the inner wall 4111 of the sealing ring 41 is greater than the height of the mounting groove 30 , so that the sealing ring 41 also abuts against the glass panel 2 , thereby preventing the plastic box body 31 from causing scratches or other damages to the glass panel 2 .

[0055] In a preferred embodiment of the present invention, Figure 1-5The switch display box 3 shown includes a box body 31 and an annular plate 32, wherein an opening is provided on one side of the box body 31 close to the lining plate 1, and the annular plate 32 is arranged around the opening of the box body 31, wherein the side of the annular plate 32 away from the box body 31 is bent downward, so that the annular plate 32 and the outer wall of the box body 31 are surrounded to form a mounting groove 30. In this embodiment, the box body 31 and the annular plate 32 are integrally formed, wherein the free end of the annular plate 32 and the open end of the box body 31 have a certain height difference, that is, the height of the outer groove wall of the mounting groove 30 is less than the height of the inner groove wall thereof, so that it is convenient for the second flange 412 to pass through the mounting groove 30 and extend to the outside of the mounting groove 30, thereby increasing the contact area between the sealing ring 41 and the lining plate 1, and improving the sealing performance of the sealing ring 41 and the lining plate 1.

[0056] In a preferred embodiment of the present invention, Figure 1-5 The switch display box 3 shown also includes a display screen 33 and a display bracket 34. The display screen 33 is arranged between the opening and the glass panel 2. The display bracket 34 is sleeved on the outer periphery of the display screen 33 and is snapped onto the inner wall of the box body 31. The outer side surfaces of the display bracket 34 and the display screen 33 are in the same plane, ensuring that the display screen 33 can be close to the glass panel 2, thereby improving the clarity and sensitivity of the switch glass assembly.

[0057] In addition, the display bracket 34 includes a bracket body 341 and a buckle 342 connected to the bracket body 341. The inner wall of the box body 31 is provided with a slot 311 corresponding to the buckle 342. The buckle 342 can be inserted into the slot 311. The installation structure is simple and convenient for subsequent maintenance.

[0058] Preferably, the outer periphery of the box body 31 is also connected with a mounting block 35, and the inner side of the lining plate 1 is provided with a mounting frame 13 corresponding to the mounting block, and the mounting block 35 is detachably connected to the mounting frame 13. After the sealing ring 41 is inserted into the mounting groove 30, the mounting block 35 and the mounting frame 13 are connected by screws to achieve the preliminary connection between the switch display box 3 and the lining plate 1, so as to strengthen the connection between the bracket 51 and the base 52.

[0059] The specific process is as follows:

[0060] First, the mounting frame 13 and the base 52 can be welded to the lining plate 1; then, the lining plate 1 is fixed to the glass panel 2 by glass glue; then, the sealing ring 41 is installed on the first flange 12, and the sealing ring 41 is inserted into the mounting groove 30 on the switch display box 3, and then, the switch display box 3 is screwed to the lining plate 1 by using the mounting block 35 and the mounting frame 13; finally, the reinforcing bracket 51 is sleeved on the top of the switch display box 3 and bolted to the base 52 located below it, because the sealing ring 41 and the mounting groove are 30 interference fit, the first flange 12 and the limiting groove 411 are interference fit, so that the sealing ring 41 can form a first sealing structure between the switch display box 3 and the lining plate 1; under the cooperation of the reinforcing bracket 51 and the base 52, a downward extrusion force can be generated on the sealing ring 41, so that the second flange 412 and the lining plate 1 are tightly attached to form a second sealing structure, and the inner wall 4111 and the glass panel 2 are tightly abutted to form a third sealing structure. The present application uses a three-layer sealing structure design to make the switch glass assembly achieve super strong sealing that is oil-proof, waterproof, and smoke-proof. At the same time, it can also make the display screen 33 firmly attached to the glass panel 2, solving the problem that the switch display box 3 cannot be attached to the glass panel 2 due to the uneven deformation of the plastic body 31, which ultimately leads to unclear display.

[0061] A kind of oil smoke suction device of the utility model embodiment, such as Figure 7 The range hood shown comprises a range hood body 6 and Figure 1-6 The switch glass assembly shown in the figure is connected to the range hood body 6. The lining plate 1, the switch display box 3, the sealing ring 41 and the fastening structure 5 work together to form a three-layer sealing structure, which not only achieves oil-proof, smoke-proof and waterproof effects, but also allows the display screen 33 to be closely attached to the glass panel 2, solving the problem that the switch display box 3 cannot be closely attached to the glass due to the uneven deformation of the box body 31, resulting in unclear display.
