When the cover body is closed, the plug-in board is released, the limit spring restores its deformation and pushes the plug-in board to move until the plug-in board abuts against the slot wall of the slot body. At this time, the limit spring, the slot body and the plug-in board cooperate to limit the cover body, thereby reducing the possibility of the cover body shaking in the height direction, thereby reducing the occurrence of noise caused by the cover body colliding with the main air duct.

[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The present application embodiment discloses a smoke exhaust device for a hot pot table. Figure 1 and Figure 2 , which is arranged on the hot pot table, comprises a main shell 1 in a rectangular ring shape, and a through hole is provided on the side wall of the main shell 1 for discharging the smoke generated by the hot pot. An air duct 11 covering the through hole is fixedly connected to the outer wall of the main shell 1, and the air duct 11 is bent downward on the side away from the main shell 1 so as to guide the smoke to the bottom of the main shell 1 for centralized treatment. A bottom plate 12 is fixedly connected to all the air ducts 11, and a main air duct 2 located below the main shell 1 is fixedly connected to the bottom plate 12, and the main air duct 2 is connected to the suction fan, and the main air duct 2 is used to discharge the concentrated smoke.
[0032] All the air ducts 11 are commonly and fixedly connected to a ring plate 13 located below the main shell 1. The ring plate 13 is rectangular and is located above the main air duct 2. A cover body 3 is sleeved on the ring plate 13. The cover body 3 is used to close the upper opening of the main air duct 2. The edge of the cover body 3 is bent downward so that the cover body 3 can better cooperate with the ring plate 13. When impurities enter the main shell 1, the impurities fall on the cover body 3, which reduces the occurrence of impurities falling into the main air duct 2, thereby reducing the adverse effects of impurities on the operation of the suction fan.
[0033] Reference Figure 2 and Figure 3 The cover 3 is slidably connected with a plug-in board 4 adapted to the slot 5. The lower surface of the plug-in board 4 is fixedly connected with a slider 41. The upper surface of the cover 3 is depressed downward to form a slide groove 31 corresponding to the slider 41. The length direction of the slide groove 31 is the sliding direction of the plug-in board 4. The slider 41 is inserted into the slide groove 31. The slider 41 cooperates with the slide groove 31 to make the plug-in board 4 and the cover 3 slide together. In order to facilitate the operator to pull the plug-in board 4, a side plate 43 is also connected to the upper surface of the plug-in board 4. The side plate 43 provides a structure that is easy to hold by hand, making the operation more convenient.
[0034] A slot body 5 corresponding to the plug-in board 4 is connected to the side wall of the air duct 11 close to the cover body 3, and the opening of the slot body 5 faces the ring plate 13, which is used to cooperate with the plug-in board 4; a limit spring 42 is fixedly connected to the side wall of the plug-in board 4 away from the corresponding air duct 11, and one end of the limit spring 42 away from the plug-in board 4 is fixedly connected to the middle part of the cover body 3. Under the elastic force of the limit spring 42, the plug-in board 4 can be inserted into the slot body 5, and the upper and lower surfaces of the plug-in board 4 are in contact with the slot wall corresponding to the slot body 5, thereby limiting the cover body 3, reducing the movement of the cover body 3 in the height direction, and reducing the noise caused by the collision between the cover body 3 and the ring plate 13.
[0035] Reference Figure 2 and Figure 4 The lower surface of the cover 3 is connected with a filter plate 6 adapted to the main air duct 2. The filter plate 6 is annular and is used to filter the air entering the main air duct 2 to remove impurities in the air. The filter plate 6 is inserted into the main air duct 2, and the outer wall of the filter plate 6 contacts the inner wall of the main air duct 2, which reduces the relative movement of the cover 3 and the ring plate 13 in the horizontal direction, thereby further reducing the possibility of the cover 3 making noise.
[0036] The lower surface of the filter plate 6 is fixedly connected to a mounting ring 72 coaxial with the filter plate 6, and the lower surface of the mounting ring 72 is vertically fixedly connected to at least two limit rods 7. In this embodiment, the number of limit rods 7 is two, and a clamping spring 8 is sleeved on the limit rod 7. The upper end of the clamping spring 8 is fixed to the lower surface of the mounting ring 72; a limit ring 71 corresponding to the limit rod 7 one by one is fixedly connected to the inner wall of the main air duct 2.
[0037] When the cover 3 is closed, the limiting rod 7 is inserted into the corresponding limiting ring 71, and the limiting rod 7 cooperates with the limiting ring 71 to limit the filter plate 6 and the cover 3, reducing the possibility of the filter plate 6 and the cover 3 rotating in the horizontal direction. At this time, the mounting ring 72 cooperates with the limiting ring 71 to compress the abutting spring 8, and the abutting spring 8 makes the upper surface of the plug-in plate 4 and the inner top surface of the groove 5 abut, thereby improving the stability of the cover 3 and the ring plate 13. When the abutting spring 8 is in a compressed state, the force of the abutting spring 8 is transmitted to the filter plate 6 through the mounting plate, so that the filter plate 6 is subjected to a more uniform force, and the deformation of the filter plate 6 is reduced.
[0038] Reference Figure 2 and Figure 3 In order to further reduce the occurrence of noise from the cover body 3, a rubber pad 32 is fixedly connected to the lower surface of the cover body 3, and the pad 32 is located on the outside of the filter plate 6; the pad 32 separates the ring plate 13 and the cover body 3, reducing the possibility of noise caused by collision between the ring plate 13 and the cover body 3.
[0039] Before closing the cover body 3, the operator pushes the side plate 43 to a position close to the middle of the cover body 3. The side plate 43 drives the plug-in board 4 to move, and the plug-in board 4 compresses the limit spring 42. When the plug-in board 4 moves into place, the operator rotates the cover body 3 to align the plug-in board 4 with the corresponding slot body 5, and the limit rod 7 with the limit ring 71, and then delivers the cover body 3 downward. During this process, the clamping spring 8 first contacts the limit ring 71. As the cover body 3 continues to move downward, the mounting ring 72 compresses the clamping spring 8, and the limit rod 7 is inserted into the limit ring 71.
[0040] When the cover 3 is lowered into place, the pad 32 contacts the upper surface of the ring plate 13, and then the side plate 43 is released. At this time, the limit spring 42 recovers its deformation and pushes the plug-in board 4 to move until the plug-in board 4 abuts against the groove wall of the groove 5. At this time, the limit spring 42, the groove 5 and the plug-in board 4 cooperate to limit the cover 3 vertically, the limit rod 7 and the limit ring 71 cooperate to limit the cover 3 circumferentially, and the tightening spring 8, the plug-in board 4 and the groove 5 cooperate to further limit the cover 3 vertically, reducing the possibility of the cover 3 shaking, thereby reducing the occurrence of noise caused by the collision between the cover 3 and the main air duct 2.
[0041] The implementation principle of a smoke exhaust device for a hot pot table in an embodiment of the present application is as follows: before closing the cover body 3, pull the side panel 43 to move the plug-in board 4 toward the middle of the cover body 3, then rotate the cover body 3 to align the limiting rod 7 with the corresponding limiting ring 71, align the plug-in board 4 with the corresponding slot body 5, and then lower the cover body 3; when the cover body 3 is moved into place, release the side panel 43, and the limiting spring 42 allows the plug-in board 4 to be inserted into the corresponding slot body 5.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
