[0015] By adopting the above technical solution, the suction of the exhaust pipe causes negative pressure to be generated inside the collection box, thereby generating negative pressure inside the cavity and generating suction in the collection hole.

[0016] The utility model is further configured as follows: a top rod is fixedly connected to the top of the sealing cover, and a filter screen is fixedly connected to the top of the top rod.

[0017] By adopting the above technical solution, the top rod supports and fixes the filter, so that dust remains on the filter, and the sealing cover can be removed for cleaning.

[0018] The utility model is further configured as follows: a discharge port is provided on the outer surface of the collecting cover, and a feed port is provided on the inner wall of the collecting cover.

[0019] By adopting the above technical solution, the feed port and the discharge port correspond to each other, and the feed port facilitates the passage of larger dust into the cavity.

[0020] The utility model is further configured as follows: a reinforcement layer is fixedly connected to the inner wall of the collection cover, and the inner wall of the reinforcement layer is coated with a wear-resistant coating.
