The other end of the spring 208 is fixedly connected to the inner wall of the limiting frame 206. A sealing sleeve is fixedly connected to the outer wall of the end plate 205. The end of the blocking block 207 located away from the spring 208 extends to the outside of the limiting frame 206, and the lower end of the side of the blocking block 207 located outside the limiting frame 206 is set as an inclined surface. The blocking block 207 at the inclined surface extends from top to bottom towards the limiting frame 206. Figure 5 As shown, the spring 208 pushes the inclined end of the block 207 to extend to the outside of the limiting frame 206;

[0029] The dust collector body 1 includes a vacuum cylinder 101. Several connecting brackets 109 are fixedly connected to the inner wall of the vacuum cylinder 101. A protective sleeve 110 is fixedly connected to the other side of each connecting bracket 109. The inner wall of the protective sleeve 110 is slidably fitted onto each diversion pipe 203. A sealing ring 211 is fixedly connected to the upper end of the inner wall of each protective sleeve 110. The inner side of the sealing ring 211 abuts against the diversion pipe 203. Figure 4 As shown, the sealing ring 211 is made of rubber and seals the gap between the top of the protective sleeve 110 and the diversion pipe 203.

[0030] Each protective sleeve 110 has a through-hole 112 at the lower end of its outer wall. The bottom surface of the through-hole 112 is beveled, and the upper inner end of the through-hole 112 is slidably connected to the end plate 205. The lower inner end of the through-hole 112 abuts against the block 207. Figures 4-5 As shown, when the diversion pipe 203 moves down along the inside of the protective sleeve 110, the block 207 gradually retracts into the inside of the limiting frame 206;

[0031] A mounting frame 105 is fixedly installed on the inner wall of the vacuum cylinder 101, above the annular tube 201. A sealing ring 106 is fixedly connected to the bottom side of the mounting frame 105, with the bottom surface of the sealing ring 106 abutting against the annular tube 201. The inner wall of the mounting frame 105 is fixedly installed with an electric telescopic rod 107, the extension end of which faces downward and is fixedly connected to the annular tube 201.Figures 1-2 As shown, when the sealing ring 106 abuts against the annular tube 201, it prevents dust from entering the interior of the mounting frame 105;

[0032] A through-tube 108 is fixedly connected to the upper part of the outer wall of the vacuum cylinder 101 and the side away from the mounting frame 105.

[0033] The working principle of this utility model:

[0034] When dust is reduced inside the dust collector body 1, the electric telescopic rod 107 pushes the annular pipe 201 to move down as a whole, so that the diversion pipe 203 moves into the protective sleeve 110. The block 207 moves down and is squeezed by the lower end of the opening 112. The bottom slope of the block 207 is subjected to a horizontal force, and then the block 207 compresses the spring 208 and retracts into the limiting frame 206. At this time, the block 207 cancels the blockage of the opening 112. When the diversion pipe 203 descends, the nozzle 204 is aligned with the opening 112. The end of the connecting hose 202 located outside the vacuum cylinder 101 is connected to the water source. The water source passes through the annular pipe 201 and the diversion pipe 203. Finally, the water source output by the nozzle 204 passes through the opening 112 and enters the vacuum cylinder 101.

[0035] Secondly, when the electric telescopic rod 107 pushes the annular tube 201 upward as a whole, the opening 112 aligns with the block 207, and the spring 208 releases its elastic potential energy to push the block 207 to re-seal the opening 112, thereby preventing dust from passing through the opening 112 and entering the interior of the protective sleeve 110.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
