AI Technical Summary
Existing sampling brushes can easily obstruct the entry of the pipette tip during the sampling process, and can also carry the sampling brush out when the pipette tip is withdrawn, leading to contamination problems.
Design a ring-shaped sampling brush that allows the pipette tip to enter through a channel formed by the upper and lower rings, avoiding obstruction of the pipette tip by the brush tip, and ensuring that the brush tip is not pulled out when the pipette tip is withdrawn after liquid aspiration.
This ensured a smooth sampling process, prevented contamination caused by the brush head being pulled out, and guaranteed the normal operation of the automated equipment.

Abstract
Claims
1. An annular sampling brush characterized by: The brush head includes a handle and a brush head. The handle includes a handle rod (1) and a connecting rod (2) connected to the handle rod (1). The brush head includes an upper ring (3), a lower ring (4), a bristle arrangement body (5), and bristles (6). The inner and outer diameters of the upper ring (3) are larger than the inner and outer diameters of the lower ring (4). The connecting rod (2) is connected to the upper ring (3). The bristle arrangement body (5) is connected between the upper ring (3) and the lower ring (4). The bristles (6) are connected to the bristle arrangement body (5). The inner diameter of the lower ring (4) is larger than the diameter of the suction head. The upper ring (3) and the lower ring (4) together form a channel (9) for the suction head to enter.
2. The annular sampling brush of claim 1, wherein: The bristle arrangement body (5) includes several rods, on which bristles (6) are implanted.
3. The annular sampling brush according to claim 1, characterized in that: The bristle arrangement body (5) includes several arc-shaped plates, on which bristles (6) are implanted.
4. The annular sampling brush of any of claims 1-3, wherein: The lower end face of the lower ring (4) is connected to bristles (6).
5. The annular sampling brush of any of claims 1-3, wherein: The lower end face of the upper ring (3) is connected to bristles (6).
6. The annular sampling brush of claim 4, wherein: At least two sets of the connecting rods (2) are provided.
7. The annular sampling brush of claim 1, wherein: The upper ring (3) and the lower ring (4) are set concentrically.
8. A sampling device, characterized by: Includes the annular sampling brush and specimen tube (7) as described in any one of claims 1-7.
9. The sampling device of claim 8, wherein: The outer diameter of the upper ring (3) is less than or equal to the inner diameter of the specimen tube (7).
10. The sampling device of claim 8, wherein: The inner diameter of the specimen tube (7) is greater than the outer diameter of the upper ring (3), and the difference between the two is 1~2mm.
