[0030] In the following description, many specific details are explained in combination with the embodiments to facilitate a full understanding of the present invention. However, it should be understood that the following embodiments and detailed descriptions are only for illustrative purposes and do not limit the scope of protection of the present invention.

[0031] The brush conveying device for cleaning endoscopes according to the utility model is as follows Figure 1-2As shown, it includes a base 10, a cleaning brush 20, a propulsion assembly 30, a guide tube 40, and a tube connector 50. The propulsion assembly 30 is specifically a belt-type assembly, but this embodiment is not limited thereto. For example, the propulsion assembly 30 may also be a pressure wheel-type assembly. Specifically, the base 10 is provided with an outwardly protruding channel tube 11. The guide tube 40 is mounted to the channel tube 11 via the tube connector 50. The brush 20 passes through the guide tube 40 and extends into the channel tube 11. Driven by the propulsion assembly 30, it can be transported forward or backward.

[0032] like Figure 3-4 As shown, the guide tube 40 is specifically arranged in a circular and circuitous manner. Exemplarily, the guide tube 40 includes multiple straight tube sections 41 and multiple curved tube sections 42, and the different straight tube sections 41 are connected by the curved tube sections 42. Preferably, the guide tube 40 is a hard tube, such as a hard rubber tube, and the diameter of the guide tube 40 is set to be larger than the diameter of the brush 20. This helps to reduce the movement of the brush 20 in the guide tube 40, thereby improving the smoothness of the brush 20 transportation.

[0033] The tube connector 50 and the guide tube 40 are preferably connected by plug-in fitting. When not in use, the guide tube 40 can be removed from the tube connector 50 for easy storage of the entire tube. The tube connector 50 and the channel tube 11 are also preferably connected by plug-in fitting. Figure 5-6 、 Figure 11 As shown, the pipe connector 50 includes a hollow connecting body 51 and a movable jaw plate 52. A through hole 521 is provided in the middle of the jaw plate 52 to avoid the channel tube 11. During installation, the channel tube 11 passes through the through hole 521 so that the connecting body 51 can be detachably connected to the channel tube 11 through the jaw plate 52.

[0034] Furthermore, an abutment portion 522 is provided on the jaw plate 52, and an inner guide groove 511 is provided on the connecting body 51. The jaw plate 52 is movably set in the inner guide groove 511 and has a locking position in which the abutment portion 522 abuts against the channel tube 11 and an unlocking position in which the abutment portion 522 is separated from the channel tube 11; preferably, a groove portion 11a is provided on the channel tube 11, and when the connecting body 51 is installed on the channel tube 11, the jaw plate 52 in the locking position extends into the groove portion 11a to form a mating connection with the channel tube 11.

[0035] like Figure 7-10As shown, an elastic member 53 is provided in the inner guide groove 511, and the elastic member 53 and the abutment portion 522 are located on opposite sides of the channel tube 11 (taking the upper and lower sides as an example); wherein, a side pressure plate 523 is provided on the jaw plate 52, and when the jaw plate 52 is pressed down and moved to the unlocking position, the abutment portion 522 avoids the channel tube 11 while the side pressure plate 523 squeezes the elastic member 53; correspondingly, when the downward pressure on the side pressure plate 523 disappears, the side pressure plate 523 and the jaw plate 52 move upward under the action of the elastic member 53 so that the jaw plate 52 switches to the locked position.

[0036] The connecting body 51 is provided with an outer guide groove 512 that is parallel to and connected to the inner guide groove 511. The upper end of the outer guide groove 512 is formed into a closed end. The jaw plate 52 is provided with a stopper 54 that protrudes into the outer guide groove 512. When the jaw plate 52 moves upward, the stopper 54 abuts against the closed end of the outer guide groove 512 to prevent the jaw plate 52 from being separated from the inner guide groove 511. Exemplarily, the jaw plate 52 is provided with a mounting hole 524. The stopper 54 is a bolt that can be assembled into the mounting hole 524. When the jaw plate 52 is installed in the inner guide groove 511 and in place, the stopper 54 limits the position of the jaw plate 52.

[0037] Furthermore, the tube connector 50 includes an inner guide sleeve 55 and an outer guide sleeve 56. The inner guide sleeve 55 is mounted to the side of the connector body 51 away from the jaw plate 52 via the outer guide sleeve 56. Exemplarily, the outer guide sleeve 56 is assembled with the connector body 51, for example, by means of threads. In this embodiment, the inner guide sleeve 55 and the outer guide sleeve 56 cooperate to guide the brush 20, allowing the brush 20, which extends through the channel tube 11, to enter the guide tube 40 directly without turning, thereby ensuring smooth transportation of the brush 20.

[0038] like Figure 12 As shown, the inner guide sleeve 55 includes a connecting ring 551 and a tapered member 552. The tapered member 552 is provided with a central through-hole 5521 for the brush 20 to pass through. When the outer guide sleeve 56 is mounted on the connecting body 51, the connecting ring 551 is pressed against the connecting body 51. Specifically, the tapered member 552 includes a plurality of guide blades 5522, which are arranged at intervals in the circumferential direction around the brush 20. The guide blades 5522 can be elastic blades, which can provide a certain degree of compression to the brush 20 during transportation, thereby facilitating the transportation of the brush 20 in a taut state.

[0039] During use, the brush body (usually a steel wire) of the brush 20 is passed through the propulsion assembly 30, the channel tube 11, and the tube connector 50 into the guide tube 40 in sequence, while keeping the brush head of the brush 20 in the working position; then, the guide tube 40 is connected to the channel tube 11 using the tube connector 50 and locked in position by the jaw plate 52; finally, the propulsion assembly 30 is started to drive the brush 20 forward and input it into the internal pipeline of the endoscope through the entrance of the endoscope for cleaning. After cleaning is completed, the propulsion assembly 30 is used to drive the brush 20 backward to complete the return of the brush 20.

[0040] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe the feasible implementation methods of the present invention, and are not used to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
