[0025] In the following description, many specific details are explained in combination with the embodiments to facilitate a full understanding of the present invention, but 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.

[0026] like Figure 1-3 As shown, the brush conveying detection device 10 of the embodiment is specifically installed on the brush input side 20a of the brush propulsion device 20, and is used to detect the conveying distance of the output brush A; wherein, the brush propulsion device 20 can be installed in the cleaning basin of the endoscope cleaning and disinfecting machine, and is used to convey the brush to the endoscope to clean the internal pipeline of the endoscope; illustratively, the brush propulsion device 20 can refer to conveying methods such as pressure wheel type and conveyor belt type, which is not limited to this in this embodiment and will not be expanded.

[0027] like Figure 1 , Figure 4-5 As shown, the brush conveying detection device 10 includes a base 11, a transmission roller 12, a clamping roller 13 and a sensor assembly 14 for detecting the number of rotations of the transmission roller 12; wherein the base 11 is specifically installed on the housing 21 of the brush conveying device 20, and a brush conveying channel 111 arranged along the first direction X is provided on the base 11, and the brush passes through the brush conveying channel 111 and is conveyed by the brush propulsion device 20.

[0028] The transmission roller 12 is arranged adjacent to the brush conveying channel 111, and is freely rotatably mounted on the base 11 and arranged along a second direction Y orthogonal to the first direction X; wherein a slewing bearing 15 is provided between the transmission roller 12 and the base 11, and the slewing bearing 15 is mounted on the base 11, for example, via a slewing seat 16.

[0029] The pressing roller 13 is movably mounted on the base 11 and can move toward the transmission roller 12; wherein the pressing roller 13 and the transmission roller 12 are respectively located on opposite sides of the brush conveying channel 111. When the pressing roller 13 moves close to the transmission roller 12, the brush passing through the brush conveying channel 111 can be pressed on the transmission roller 12, so that the transmission roller 12 rotates synchronously with the conveying of the brush. Exemplarily, the pressing roller 13 includes a fixed shaft 131 and a rotating ring 132 mounted on the fixed shaft 131, and the rotating ring 132 can rotate along with the conveying process of the brush.

[0030] Furthermore, the pressing roller 13 is located directly above the driving roller 12, and the two are preferably parallel to each other. The base 11 is provided with a floating pressing seat 17 having a high position and a low position, and the floating pressing seat 17 can be specifically arranged on the housing 21; the pressing roller 13 is installed on the floating pressing seat 17, for example, by means of a connecting block 18, and presses the brush on the driving roller 12 when the floating pressing seat 17 is in the low position.

[0031] For example, the housing 21 is provided with a guide rod 22 and a reset spring (not shown in the figure), the floating pressing seat 17 is arranged on the guide rod 22 and can move from a high position to a low position relative to the guide rod 22, while squeezing the reset spring; when the floating pressing seat 17 is in a low position, its position can be locked by a self-locking component 23, thereby keeping the pressing roller 13 always pressing the brush on the transmission roller 12, so as to maintain the synchronization between the rotation process of the transmission roller 12 and the conveying process of the brush. Among them, the self-locking component 23 is, for example, a bolt locking mechanism, a snap-on locking mechanism, a spring reset locking mechanism, etc., which is not limited in the embodiment and will not be expanded.

[0032] Please continue reading Figure 4-5 The transmission roller 12 has a first end 12a for transmission and a second end 12b for detection. A flexible sleeve 121 is preferably provided at the first end 12a. The flexible sleeve 121 can produce elastic deformation, which is conducive to increasing the contact area and friction between the transmission roller 12 and the brush. Among them, at least one detection point 122 is provided at the end surface of the second end 12b, for example, two symmetrically distributed detection points 122. The sensor assembly 14 includes an electric control board 141 and a sensor 142 connected to the electric control board 141. The sensor 142 is, for example, a Hall sensor, which is arranged on the outer side of the end surface of the second end 12b for detecting the detection point 122; the electric control board 141 can calculate the actual distance the brush is transported according to the detection result of the sensor 142.

[0033] In the embodiment, the brush can be pressed on the transmission roller 12 by the action of the pressing roller 13. As the brush is transported, the transmission roller 12 rotates appropriately and the number of rotations of the transmission roller 12 is detected by the sensor 142 component 14. The actual distance of the brush transport can be accurately calculated according to the diameter of the transmission roller 12. When a blockage occurs or the brush is not transported smoothly, the brush transport slows down. At this time, the brush can be transported in the opposite direction of the aforementioned transport direction for a set distance, such as 20 cm, and recorded by the sensor 142 component 14; then continue to transport again in the aforementioned transport direction for secondary cleaning. Repeating the above process can perform multiple cleanings at the same location.

[0034] Although the present invention is 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 protection scope 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 protection scope defined by the claims of the present invention.
