After the endoscope is placed in place and the relevant pipeline connections are completed, the upper cover 12 is closed and the cleaning operation begins.

[0048] The pipeline system has a plurality of outlets 13 extending into the cleaning basin 20 to supply cleaning fluids such as cleaning liquid, enzyme liquid, disinfectant liquid and drying gas into the cleaning basin 20. Figure 4-5 As shown, a cleaning liquid tank 14, two liquid storage tanks 15 and a gas generating device 16 are provided on the frame body 11. The two liquid storage tanks 15, the cleaning liquid tank 14 and the gas generating device 16 are all arranged below the cleaning basin 20 and are arranged in sequence at intervals in the front-to-back direction. The two liquid storage tanks 15 are arranged side by side in the left-right direction for storing enzyme liquid and disinfectant.

[0049] Among them, the pipeline system includes a plurality of connected or unconnected pipelines, and the cleaning liquid in the cleaning liquid tank 14, the enzyme liquid and disinfectant in the liquid storage tank 15, and the drying gas output by the gas generating device 16 are respectively supplied to the cleaning basin 20 and the endoscope through different pipelines to complete the internal and external cleaning of the endoscope. Preferably, a discharge pipe is provided on the cleaning basin 20, and the used cleaning medium is directly discharged through the discharge pipe or part of the cleaning liquid with low contamination content is circulated to the cleaning liquid tank 14 for recycling. The connection method of the pipeline is not limited in the embodiment, as long as the supply of the cleaning medium can be achieved.

[0050] like Figure 6-7 As shown, the cleaning device 30 includes a shell 31, a winding mechanism 32, a conveying mechanism 33 and a detection mechanism 34; wherein the conveying mechanism 33 is used for outputting and retrieving the brush A, the winding mechanism 32 is used to store the brush A in a winding manner and cooperate with the conveying mechanism 33 to output and retract the brush A, and the detection mechanism 34 is used to detect whether the brush A is normally conveyed and to detect the conveying distance of the brush A.

[0051] The endoscope has three internal pipelines. In order to automatically clean the three internal pipelines separately without disassembly, the output position of the brush A in the embodiment can be switched; specifically, a switching mechanism 35 and three outlet conduits 311 are provided on the housing 31. The three outlet conduits 311 correspond to the three internal pipelines of the endoscope respectively. The conveying mechanism 33 is arranged on the switching mechanism 35 as a whole and switches between the positions corresponding to the three internal pipelines under the drive of the switching mechanism 35. The switching modes of the switching mechanism 35 include sliding mode, swinging mode and multi-axis motion mode, for example, Figure 6-7 The swing pattern shown.

[0052] The conveying mechanism can be a friction conveying mechanism, such as a belt conveying mechanism or a wheel conveying mechanism, or a clamping conveying mechanism, as long as it can realize the conveying of the brush. For example, the wheel conveying mechanism is used as an example for further description. Figure 8-9 As shown, the conveying mechanism 33 includes a conveying base 331, a supporting wheel assembly 332, a clamping wheel assembly 333 and a self-locking assembly 334; the conveying base 331 is installed on the shell 31 to provide installation space for the supporting wheel assembly 332, the clamping wheel assembly 333 and the self-locking assembly 334; wherein, a conveying channel 335 for the brush A to pass through is provided on the conveying base 331, and the conveying channel 335 is used to provide a conveying guide for the brush A to prevent the brush from deviating during the conveying process.

[0053] The support wheel assembly 332 includes at least one support wheel 3321, and the pressure wheel assembly 333 includes at least one pressure wheel 3331 corresponding to the support wheel 3321. In the conveying direction of the brush A, the support wheel 3321 and the pressure wheel 3331 are respectively located on the opposite sides of the brush A, specifically, for example, on the upper and lower sides; wherein, the support wheel 3321 is preferably fixed in the height direction, and can be rotated to convey the brush A under the drive of the conveying drive assembly, and the pressure wheel 3331 can move relative to the support wheel 3321. When the brush A passes through the surface of the support wheel 3321, the pressure wheel 3331 can move toward the support wheel 3321 and press the brush A, thereby realizing the conveyance of the brush A by the rotation of the support wheel 3321.

[0054] like Figure 10-11 As shown, the pressure wheel assembly 333 also includes a floating pressure seat 3332, a guide rod 3333 and a reset spring. The number of the guide rods 3333 is preferably multiple. The floating pressure seat 3332 is set on the guide rod 3333 and can move from a disengaged position to a pressure position relative to the guide rod 3333 while squeezing the reset spring; the pressure wheel 3331 can be rotatably mounted on the floating pressure seat 3332 and move toward and away from the support wheel 3321 along with the floating pressure seat 3332.

[0055] When the floating pressing seat 3332 is in the pressing position, its position can be locked by the self-locking component 334 to maintain continuous delivery of the brush. Figure 10-11 The self-locking assembly 334 includes a toggle shaft 3341, a driving cam 3342 and a locking member 3343. The toggle shaft 3341 is arranged in a direction parallel to the conveying channel 335, the driving cam 3342 is arranged on the toggle shaft 3341, and the locking member 3343 is arranged on the upper substrate 3311 of the conveying base 331; wherein, one end of the toggle shaft 3341 is preferably provided with a gripping handle 3344, and the gripping handle 3344 is manually rotated to drive the toggle shaft 3341 to rotate to change the position of the driving cam 3342, and then the driving cam 3342 acts on the floating pressing seat 3332, specifically on the top of the floating pressing seat 3332, so that the floating pressing seat 3332 switches between the disengaged position and the clamping position.

[0056] like Figure 12-13 As shown, a notch portion 3345 is provided on the toggle shaft 3341, and a locking portion 3346 matched with the notch portion 3345 is provided on the locking member 3343. When the toggle shaft 3341 is rotated to drive the driving cam 3342 to drive the floating clamping seat 3332 to move to the clamping position, the notch portion 3345 is exposed and can cooperate with the locking portion 3346 on the locking member 3343. The locking portion 3346 is used to lock the toggle shaft 3341 in the current position and prevent it from rotating.

[0057] Furthermore, the upper base plate 3311 is provided with a hinge shaft 3312 parallel to the driving shaft 3341, the middle part of the locking member 3343 is connected to the hinge shaft 3312 and can be rotated compared to the hinge shaft 3312, and the locking portion 3346 is arranged on the side of the hinge shaft 3312 close to the driving shaft 3341; wherein, for the convenience of operation, a lifting spring 3347 is provided on the upper base plate 3311, and the lifting spring 3347 contacts the side of the locking member 3343 away from the driving shaft 3341 and drives it to lift upward, so that the locking portion 3346 always has a tendency to press downward, and when the driving shaft 3341 rotates until the notch portion 3345 is exposed, the locking portion 3346 can be automatically pressed down under the drive of the lifting spring 3347 to form a match with the notch portion 3345.

[0058] Please refer again Fig. 9A limiting portion 3313 is provided on the upper base plate 3311, preferably near the holding handle 3344, and the limiting portion 3313 is used to limit the maximum angle of positive rotation of the driving shaft 3341, at which the notch portion 3345 can be exposed; illustratively, the notch portion 3345 is an L-shaped groove toward the locking portion 3346, and the locking portion 3346 is a protrusion adapted to the notch portion 3345. When the driving shaft 3341 is rotated until the notch portion 3345 is exposed, the locking portion 3346 abuts against a side wall of the notch portion 3345 toward the hinge shaft 3312 and limits the reverse rotation of the driving shaft 3341, thereby locking the position of the driving shaft 3341 and the driving cam 3342.

[0059] When the lock needs to be released, it can be completed by pressing the locking member 3343 away from the side of the driving shaft 3341 under the action of external force. At this time, the restrictive effect of the locking part 3346 on the notch part 3345 disappears. The driving shaft 3341 is manually rotated in the opposite direction to drive the driving cam 3342 to rotate. The reset spring can realize the automatic lifting of the floating clamping seat 3332 and switch it to the disengaged position.

[0060] In the embodiment, the number of support wheels 3321 and pressure wheels 3331 is two, wherein the two pairs of support wheels 3321 and pressure wheels 3331 are respectively located at the entrance and exit of the conveying channel 335; in other embodiments, the conveying channel 335 can be provided with multiple sections, and the number of support wheels 3321 and pressure wheels 3331 can also be, for example, three, four or even more, which is not limited here and will not be expanded.

[0061] Exemplarily, the multiple support wheels 3321 are driven by, for example, a synchronous belt and a tensioning wheel, so that the multiple support wheels 3321 rotate synchronously. Further, one of the support wheels 3321 is preferably provided with an input gear 336, and a conveying motor and a transmission gear assembly are also provided on the conveying base 331 to transmit power to the input gear. Preferably, the input gear 336 is a bevel gear to save the space occupied by the drive structure and make the structure more compact.

[0062] The detection mechanism 34 is arranged on the conveying mechanism 33, and is used to detect the conveying of the brush A; the detection mechanism 34 mainly includes a first detection mechanism 34a and a second detection mechanism 34b. The first detection mechanism 34a is arranged on the output side of the brush A of the conveying mechanism 33 to detect whether the brush A is conveyed normally, that is, to detect whether the brush A is conveyed normally, especially whether it is conveyed normally after switching to multiple positions of different catheters; the second detection mechanism 34b is arranged on the input side of the brush A of the conveying mechanism 33 to detect the conveying distance of the brush A, and judge whether the pipeline of the endoscope is blocked according to the detection result to achieve focused cleaning of the blocked area.

[0063] like Figure 14-19 As shown, the first detection mechanism 34a includes a detection platform 341, a detection component 342, a trigger component 343 and a detected component 344 linked to the trigger component 343; the trigger component 343 is movably installed on the detection platform 341 and has an initial position and two detection positions, the detection component 342 is installed on the detection platform 341 and corresponds to the detected component 344; wherein, a channel 3411 is provided on the detection platform 341, the trigger component 343 can contact with the brush A passing through the channel 3411 and be pushed from the initial position to the detection position by the brush A, and drive the detected component 344 to generate a detection signal that follows and changes the detection component 342.

[0064] Exemplarily, when the trigger component 343 is in the initial position, the detected component 344 can be detected by the detection component 342 and send out a first signal; when the trigger component 343 moves to a non-initial position, the detected component 344 cannot be detected by the detection component 342 and send out a second signal; therefore, the trigger component 343 can have a plurality of detection positions at which the detected component 344 cannot be detected by the detection component 342, so that no matter whether the brush A is being transported in the forward or reverse direction, as long as the trigger component 343 is pushed away from the initial position during the transportation of the brush A, it is possible to detect whether the brush A is being transported normally.

[0065] Furthermore, the detection platform 341 is provided with a swing shaft 345 which is orthogonal to the conveying direction of the brush A, and the swing shaft 345 is located at the first side of the channel 3411; the trigger member 343 is fixedly arranged on the swing shaft 345, and the trigger member 343 is in an initial position perpendicular to the conveying direction of the channel 3411 and can be switched to the detection position as the swing shaft 345 swings forward or backward. The connection between the swing shaft 345 and the detection platform 341 is preferably provided with a bearing or a low-friction fit, so that the trigger member 343 and the swing shaft 345 can be smoothly driven to swing when the brush A is conveyed, and it is also helpful to ensure that the trigger member 343 will not or will not affect the conveying of the brush A.

[0066] In order to maintain the automatic switching of the trigger member 343, a floating component 346 may be further provided on the detection platform 341 in the embodiment. The floating component 346 is used to keep the trigger member 343 in the initial position when there is no brush A conveying in the channel 3411 and can be pushed away to the detection position when the brush A is conveyed in the forward and reverse directions; please continue Figure 16-19The floating assembly 346 includes a floating member 3461 and two floating elastic members 3462. The two floating elastic members 3462 act on opposite sides of the floating member 3461 to maintain the balance of the floating member 3461. Specifically, the floating elastic member 3462 is a straight spring, one end of which is connected to the floating member 3461 and the other end is connected to the detection platform 341; wherein the two straight springs are aligned in the length direction. Preferably, the two floating elastic members 3462 preferably adopt the same specifications.

[0067] Among them, the swing shaft 345 is provided with a gear part 3451, and the floating member 3461 is provided with a rack part 3463 meshing with the gear part 3451; under the coordinated action of the two floating elastic members 3462, the floating member 3461 can drive the swing shaft 345 to rotate through the rack part 3463 and the gear part 3451 so that the trigger member 343 has a movement trend of switching from the detection position to the initial position. The floating component 346 in the embodiment adopts a force balance method through the rack part 3463 on the floating member 3461 and the gear part 3451 on the swing shaft 345 to control the position of the trigger member 343, and appropriately adapts to the detection of the brush A that needs to be transported in the forward and reverse directions.

[0068] Please continue reading Figure 14-15 , the detection platform 341 is also provided with a push member 3412, which is located at the second side of the channel 3411 and corresponds to the trigger member 343; wherein, when the brush A passes between the push member 3412 and the trigger member 343, it can be restricted by the push member 3412 and drive the trigger member 343 to be pushed away from the initial position to the detection position. Further, the detection platform 341 is provided with a push elastic member 3413, which is used to make the push member 3412 have a movement tendency to move toward the contact member; wherein, when the brush A passes between the push member 3412 and the trigger member 343, the push elastic member 3413 is compressed.

[0069] The push member 3412 has a guiding surface facing the trigger member 343. When the brush A passes between the push member 3412 and the trigger member 343, it can be guided by the guiding surface and move toward the side close to the trigger member 343; preferably, the guiding surface is an arc-shaped guiding surface to facilitate the brush A to be smoothly transported between the push member 3412 and the trigger member 343.

[0070] like Figure 20-21As shown, the second detection mechanism 34b includes a transmission roller 347 and a detection component corresponding to the transmission roller 347. The transmission roller 347 is arranged on the conveying path of the brush A and rotates as the brush A is conveyed. The detection component includes a sensor 348 arranged at the transmission roller 347. The sensor 348 is used to detect the number of rotations of the transmission roller 347. Exemplarily, the sensor 348 is a Hall sensor.

[0071] The transmission roller 347 is preferably installed on the conveying base 331 through a bearing, and a detection ring 3471 is provided at the other end of the transmission roller 347 away from the brush A, and the sensor 348 corresponds to the detection ring 3471.

[0072] To keep the transmission roller 347 and the brush A in synchronous motion, please continue to refer to Fig.21 The second detection mechanism further includes a pressing roller 349, and the pressing roller 349 and the transmission roller 347 are located on opposite sides of the brush A; wherein the pressing roller 349 can rotate with the conveyance of the brush A and simultaneously press the brush A against the transmission roller 347 to avoid relative displacement between the brush A and the transmission roller 347. Preferably, the pressing roller 349 is arranged on the floating pressing seat 3332 through a connecting block 3491, and can be raised and lowered along with the floating pressing seat 3332.

[0073] Preferably, at least one of the transmission roller 347 and the pressing roller 349 is provided with a flexible sleeve that can generate deformation; wherein, the transmission roller 347 is preferably provided with a flexible sleeve, which can increase the contact area and friction between the transmission roller 347 and the brush A; in the embodiment, under the action of the pressing roller 349, the brush A can be pressed on the transmission roller 347, and as the brush A is conveyed, the transmission roller 347 generates an adaptive rotation and the number of rotations of the transmission roller 347 is detected by the detection component, and the actual distance conveyed by the brush A can be accurately calculated according to the diameter of the transmission roller 347. When a blockage occurs or the brush A is not conveyed smoothly, the conveyance of the brush A slows down. At this time, the brush A can be conveyed in the direction opposite to the aforementioned conveying direction for a set distance, such as 20 cm, and recorded by the detection component; then continue to convey it again in the aforementioned conveying direction for secondary cleaning. Repeating the above process can perform multiple cleanings at the same position.

[0074] like Figure 22-25As shown, the winding mechanism 32 in the embodiment includes a winding base 321, a wire reel 322 and a rotating member 323; the winding base 321 is mounted on the housing 31, the brush A is stored on the wire reel 322 in a wound form, the wire reel 322 is arranged on the rotating member 323 and can rotate under the drive of the rotating member 323, and the wire reel 322 can also rotate relative to the rotating member 323. Among them, a movable engaging member 324 is provided on the wire reel 322, and the engaging member 324 has a first position separated from the rotating member 323 so that the wire reel 322 can rotate independently and a second position engaged with the rotating member 323 so that the wire reel 322 and the rotating member 323 rotate synchronously.

[0075] When the engagement member 324 is in the first position and separated from the rotating member 323, the brush A can be transported forward under the drive of the conveying mechanism 33, and the brush A can be used to drive the wire reel 322 to rotate in the forward direction to be continuously released; when the engagement member 324 is in the second position and engaged with the rotating member 323, the wire reel 322 can be directly driven by the rotating member 323 and rotate in the reverse direction to continuously reel the brush A. In the embodiment, the wire reel 322 is engaged or separated from the rotating member 323 by the engagement member 324. When separated, the wire reel 322 can rotate without power to adaptively release the brush A.
