Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a pliers cleaning brush that is easy to clean, comprising:

[0024] Handle 1, which includes a handle 11, and a quick-release assembly 12 is provided on the outer circumferential surface of the handle 11;

[0025] The quick-release assembly 12 includes a movable collar 121. The bottom end of the grip 11 is slidably connected to the movable collar 121, which is in contact with the outer circumference of the grip 11, through a return spring. The inner wall of the movable collar 121 is provided with a slot 122, and the lower part of the grip 11 is provided with a slot 123. There are multiple slots 123, which are arranged in a circumferential array along the central axis of the grip 11. The slots 123 are provided with limiting balls 124.

[0026] Brush head 2 includes brush rod 21, which is hollow. Flexible bristles 22 are fixedly connected to the outer circumference of brush rod 21. A connector 24 is fixedly connected to the top of brush rod 21. A limiting ring groove 25 that fits with the outer surface of limiting ball 124 is opened on the outer circumference of connector 24.

[0027] An input tube that communicates with external cleaning fluid is fixedly connected to the center of the handle 11.

[0028] The outer circumference of the brush rod 21 is provided with liquid outlet holes 23, and multiple sets of liquid outlet holes 23 are arranged in a circular array around the central axis of the brush rod 21.

[0029] A ring frame 13 is fixedly connected to the outer circumference of the handle 11 near the brush bar 21. The ring frame 13 is rotatably connected to a ring plate 14 that fits against the outer circumference of the handle 11 through a cavity inside it. A guide rod 15 is fixedly connected to the outer circumference of the ring plate 14. The guide rod 15 is provided in multiple sets and is arranged in an array along the central axis of the handle 11. A limiting arc plate 16 is slidably connected to the outer surface of the guide rod 15, and an anti-slip pad 17 is fixedly installed on the inner wall of the limiting arc plate 16.

[0030] A compression spring 18 is fixedly connected to the middle of the inner wall of the limiting arc plate 16. The end of the compression spring 18 away from the limiting arc plate 16 is fixedly connected to the outer surface of the ring plate 14. A baffle is fixedly connected to the end of the guide rod 15.

[0031] The slot 122 is conical, and the outer circumferential surface of the movable collar 121 is provided with an anti-slip groove.

[0032] The operator pulls down the movable collar 121, which compresses the return spring. As the movable collar 121 moves, the groove 122 on its inner wall gradually aligns with the slot 123. At this point, the limiting ball 124 moves along the slot 123 into the groove 122. The operator then inserts the connector 24 on the brush rod 21 into the handle 11, connecting the connector 24 to the input tube. After insertion, the operator releases the handle. With the assistance of the return spring, the movable collar 121 will reset, and the inner wall of the movable collar 121 will re-seal the slot 123. Under the pressure of the inner wall of the movable collar 121, the limiting ball 124 will move along the slot 123 until the limiting ball 124 is engaged in the limiting ring groove 25 on the surface of the connector 24. This allows for quick assembly and disassembly between the brush rod 21 and the handle 11, making it convenient for operators to disassemble the brush head 2 for cleaning.

[0033] It is worth noting that the slot 123 adopts a conical design, and a part of the limiting ball 124 can extend out of the slot 123. With the equal-divided limiting ring groove 25 on the connector 24, quick assembly and disassembly between the brush head 2 and the handle 11 can be achieved. Since the limiting ball 124 is elliptical, when the maximum diameter of the limiting ball 124 is engaged in the conical slot 123, it will prevent the limiting ball 124 from completely disengaging from the slot 123, affecting its limiting, and causing the connection between the handle 11 and the brush head 2 to be loose, resulting in the leakage of cleaning fluid.

[0034] Then, the operator inserts the brush rod 21 into the endoscope's clamp channel opening and simultaneously pulls the limiting arc plate 16. When the flexible bristles 22 are fully inserted into the clamp channel (the flexible bristles 22 are made of a soft and elastic material, such as nylon bristles. This material ensures cleaning effectiveness while reducing scratching of the clamp channel's inner wall, and the bristles undergo quality testing to ensure they do not easily fall off under normal use), the limiting arc plate 16 is released, with the assistance of the compression spring 18. The limiting arc plate 16 will fit against the outer surface of the endoscope forceps cannula. Because the limiting arc plate 16 is equipped with an anti-slip pad 17, it increases the friction between the limiting arc plate 16 and the outer surface of the endoscope forceps cannula, thereby positioning the brush head 2. This ensures that the brush head 2 always coincides with its central axis within the endoscope forceps cannula, preventing the brush head 2 from changing position and coming into contact with the inner wall of the endoscope forceps cannula during cleaning, thus avoiding scratches and affecting its normal use. Finally, the operator delivers cleaning fluid through the input tube to the brush handle 21, and with the help of the dispensing hole 23, the cleaning fluid can be sprayed into the forceps cannula. Rotating the handle 11 completes the cleaning of the forceps cannula.
