[0016] The technical solution of the present utility model will be further described below through embodiments in conjunction with the drawings.

[0017] Embodiment:

[0018] A cleaning brush for small-caliber reagent bottles in this embodiment, as Figure 1 shown, includes a rod body 1, a movable rod 2, a movable block 4 and a plurality of cleaning ball strips. The rod body 1 is hollow inside. The movable rod 2 is inserted into the rod body 1 and extends out of the rod body 1 at both ends. A cleaning ball is fixedly arranged at the lower end of the movable rod 2. In addition, a connecting rod 5 equal in number to the cleaning ball strips is rotatably arranged at the lower end of the movable rod 2. The end of the connecting rod 5 is rotatably connected to the lower end of the cleaning ball strip. The upper end of the cleaning ball strip is rotatably connected to the vertical rod 6. The upper end of the vertical rod 6 is fixedly connected to the movable block 4. The movable block 4 is sleeved on the rod body 1. The cleaning ball strip includes a flexible rod body 7 and a plurality of cleaning balls 8 distributed on the flexible rod body. Each cleaning ball strip surrounds the rod body. The cleaning ball strip has a slight curvature when not stressed. By adjusting the length of the lower end of the movable rod extending out of the rod body and the position of the movable block on the rod body, the curvature of the cleaning ball strip can be changed so that the cleaning ball strip can be attached to the inner wall of the reagent bottle.

[0019] In this embodiment, the movable rod includes an upper rod body and a lower rod body arranged coaxially. The upper rod body is rotatably connected to the lower rod body. The surface of the upper rod body is provided with a first thread, and the inner wall of the upper end of the rod body is provided with a second thread matching the first thread. The upper end of the upper rod body is provided with a force application part for facilitating the rotation of the upper rod body. By rotating the force application part, the upper rod body can be rotated. Through the cooperation of the first thread and the second thread, the upper rod body can be raised or lowered. When the upper rod body is raised or lowered, the lower rod body can be driven to rise or fall, thereby adjusting the length of the movable rod extending from the lower end of the rod body and fixing the movable rod for cleaning operations. By adjusting the length of the lower end of the movable rod extending from the rod body, the bottom diameter of the cleaning column composed of the cleaning brushes can be changed, and reagent bottles with different bottom diameters can be adapted.

[0020] As Figure 2 shown, the movable block 4 is annular. A number of spring pins 9 are annularly distributed inside the movable block 4. The pin heads of the spring pins 9 extend from the inner wall of the movable block 4. A number of grooves 10 matching the pin heads are provided on the side wall of the rod body 1. When adjusting the position of the movable block, directly slide the movable block along the rod body. After the movable block moves to a suitable position, the pin head is embedded in the groove 10 to fix the movable block.

[0021] When the cleaning brush for small-caliber reagent bottles in this embodiment is in use, first place the movable block at the upper end of the rod body, and try to retract the lower end of the movable rod into the rod body as much as possible to ensure that the cleaning brush can extend into the bottle body through the small-caliber bottle mouth. Then rotate the upper rod body to make the lower end of the movable rod extend out of the rod body until the cleaning balls at the lower end of the cleaning ball strip are in contact with the edge of the bottom of the reagent bottle. Then adjust the position of the movable rod on the rod body so that the cleaning ball strip is in contact with the inner part of the reagent bottle body. Finally, rotate the rod body or the bottle body to clean the inner wall of the reagent bottle.

[0022] Embodiment 2:

[0023] The difference between the cleaning brush for small-caliber reagent bottles in this embodiment and that in Embodiment 1 is that, as Figure 3 shown, in this embodiment, a first flexible rod 11 is rotatably arranged at the lower end of the rod body 1, and the end of the first flexible rod 11 is rotatably connected to the lower end of the cleaning ball strip. The setting of the first flexible rod can support the lower end of the cleaning ball strip and provide the cleaning effect of the lower end of the cleaning ball strip on the bottom of the reagent bottle.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
