The risk of formation of vortex flows in the collection tank 1 is further reduced, so that the collection efficiency of particles in the collection tank 1 is stabilized. The wind deflector 5 may be a conventional stainless steel sheet or a conventional plastic material.

A gap is formed between the outer wall of the wind shield 5 and the inner wall of the shielding cylinder 2. The gap between the wind shield 5 and the shielding cylinder 2 mainly enables air flow to flow between the wind shield 5 and the shielding cylinder 2 more smoothly, and the gap can reduce resistance of the air flow. Thereby helping to reduce excessive interference of the wind deflector 5 with the airflow and maintain a more stable airflow.

If no gap exists between the shielding cylinder 2 and the outer wall of the wind shield 5, the joint of the shielding cylinder 2 and the wind shield 5 is shielded in multiple directions, so that turbulent flow is easy to occur when air flow enters the region; the clearance between the wind shield 5 and the shielding cylinder 2 ensures that the air flow can pass smoothly, and the risk of excessive interference or blockage of the air flow can be reduced.

Based on the above embodiment, referring to fig. 2 and 4, another embodiment of the present utility model is that the mounting grooves 201 are vertically distributed on the side wall of the shielding cylinder 2, the number of the mounting grooves 201 is more than two, each mounting groove 201 is used for mounting the holder 3, and the edge of the wind deflector 5 is respectively held by the holder 3.
