[0039] In one embodiment, Figure 2 , Figure 3 , Figure 4 As shown, the sealing assembly 3 also includes a sealing film cloth 36, both sides of which are respectively located in the corresponding guide rails 2, one end of the sealing film cloth 36 is fixedly connected to the support bar 31, and the other end passes through the support cylinder 33 from the reeling opening 35 and is fixedly connected to the reeling shaft 34. At the same time, a reeling member is provided on the support cylinder 33, and the reeling member is used to control the forward or reverse rotation of the reeling shaft 34 to realize the unwinding operation of the sealing film cloth 36.

[0040] In one embodiment, Figure 1 , Figure 3 As shown, at least one limiting rod 4 is provided between a pair of guide rails 2, and the limiting rod 4 is abutted and limited by the corresponding support strip 31 to achieve the limitation of the maximum sliding stroke of the sealing membrane cloth 36 and other components. At the same time, the side wall of the limiting rod 4 is provided with a step groove 5, and the support strip 31 can be embedded in the corresponding step groove 5 to improve the sealing effect between the limiting rod 4 and the support strip 31.

[0041] In order to more clearly show the relationship between the number and position of the sealing assembly 3 and the limiting rod 4, the specific example is as follows:

[0042] One: The sealing assembly 3 is provided with a group, and the limiting rod 4 is provided with a

[0043] like Figure 5 As shown, the support tube 33 is located at one end of the guide rail 2, the limit rod 4 is located at the other end of the guide rail 2, and the step groove 5 is arranged on the side of the limit rod 4 facing the support tube 33. When the support bar 31 drives the sealing film cloth 36 to move, the reeling shaft 34 unwinds the sealing film cloth 36 until the support bar 31 is embedded in the step groove 5, and the sealing film cloth 36 closes the opening of the odor-causing area.

[0044] 2: There are two sets of sealing components 3, and one limit rod 4

[0045] like Figure 6As shown, the support cylinders 33 on the two sets of sealing components 3 are located at the corresponding ends of the guide rail 2, the limit rod 4 is located at the middle position of the guide rail 2, and the two side walls of the limit rod 4 are respectively provided with step grooves 5. When the two support bars 31 are synchronously close to each other, the two support bars 31 respectively drive the corresponding sealing film cloth 36 to move, and the two reeling shafts 34 respectively discharge the sealing film cloth 36 until the two support bars 31 are respectively embedded in the corresponding step grooves 5, and the two sealing film cloths 36 jointly close the opening of the odor-causing area.

When the two support bars 31 are synchronously approached to each other, until the two support bars 31 are respectively embedded in the corresponding step grooves 5, the two sealing membranes 36 jointly seal part of the opening of the odor-causing area. Another support bar 31 slides until the support bar 31 is embedded in the corresponding step groove 5, and the three sealing membranes 36 jointly seal the opening of the odor-causing area.
