[0029] In this embodiment, the sealing unit 22 includes a connecting cylinder 221 fixedly installed at the bottom of the connecting pipe 216 by bolts. An installation cylinder 222 is fixedly installed inside the connecting cylinder 221, and a limiting plate 223 is slidably installed inside the installation cylinder 222. A connecting column 224 is fixedly installed at the bottom of the limiting plate 223, and a pressure plate 226 is fixedly installed at the bottom of the connecting column 224.

[0030] An installation cylinder 222 is fixedly installed inside the connecting cylinder 221, and a limit plate 223 is slidably installed inside the installation cylinder 222. A connecting column 224 is fixedly installed at the bottom of the limit plate 223, and a pressure plate 226 is fixedly installed at the bottom end of the connecting column 224. This realizes the basic structure of the sealing unit 22, provides support for the automatic sealing function, and ensures stability and reliability during operation.

[0031] In this embodiment, an annular plate 227 is fixedly installed inside the connecting cylinder 221, and the pressure plate 226 slides and contacts the annular plate 227 through the limiting plate 223 and the connecting column 224, thereby sealing the internal space of the connecting pipe 216 and the connecting cylinder 221. This is used to prevent external dust from entering the interior of the S-tube 215 when the collection bucket 217 is removed. A sealing gasket 228 is fixedly installed above the annular plate 227 to achieve sealing when the annular plate 227 contacts the pressure plate 226.

[0032] Used to prevent external dust from entering the interior of S-tube 215 when the collection tank 217 is removed, and a sealing gasket 228 is fixedly installed above the ring plate 227 to achieve a seal when the ring plate 227 contacts the pressure plate 226, thereby enhancing the sealing effect and preventing contaminants from entering the system.
