[0002] A dust collector is a device that separates dust from flue gas, also called dust removal equipment. Dust collectors are not only widely used in industrial fields, such as industrial workshops and construction sites, but also commonly found in offices and home environments. For example, household dust collectors are professionally designed to suck garbage and dust near the suction nozzle into the dust collector with the airflow under the condition of negative pressure difference, and then are discharged after being filtered by the filter, thus completing the cleaning task.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention sets a connecting assembly at one end of the suction rod, and the connecting assembly includes a replacement part, a pressing part, and a connecting part. The corresponding connecting part is selected according to the size of the suction head. The connecting part moves along the moving space to adjust the position. After the selection is made, the arc tops located at the upper and lower ends of the suction head seat are pressed as above. The arc tops are forced to squeeze the compression spring, so that the adjustment column moves downward along the spring groove. The adjustment column also moves along the fixed groove to the inside of the moving groove. Then the suction head seat is rotated, and the connecting part to be used is rotated to the front end of the sealing seat. At this time, the arc top will rotate to the fixed groove. After the extrusion force is lost, the compression spring is compressed. The spring rebounds and the adjustment column is inserted into the fixing groove for fixing. When replacing suction heads of different sizes, the position of the connection part is adjusted by rotating and the corresponding size is selected for fixing. This improves flexibility and eliminates the need to always disassemble the connection parts and replace the connection parts of the corresponding sizes. This saves time and effort and improves flexibility. Moreover, they are all concentrated together and stored independently when not in use, which is convenient for quick replacement and not easy to lose. This improves flexibility and solves the problem that most of the existing dust collector suction heads are replaced with multiple suction heads corresponding to a single connector, which is inconvenient to fix suction heads of different sizes and requires disassembly and replacement of the connector, and has poor adaptability.

[0021] (2) By sleeveing ​​one end of the lower pressure plate on the outside of the connecting column through a rotating ring seat and rotating it along the connecting column, when it is inconvenient for a person to press the arc top into the movable groove with his fingers, the lower pressure plate is rotated along the rotating inner groove, the position of the lower pressure column is adjusted to the upper end of the arc top that needs to be pressed, and then the lower pressure column end of the lower pressure plate is pressed to drive the arc top to move downward, which is convenient for use by different people and scenes and improves flexibility.
