Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an endoscope cleaning and disinfection machine. Background Technology

[0002] During endoscopic procedures, patients' blood, mucus, and tissue debris may remain inside the endoscopic tubing. Therefore, after each use of the endoscope, medical staff must clean the inside and outside of the tubing to remove any residue.

[0003] Currently, endoscope cleaning is generally performed manually by medical staff in the department using the endoscope. When cleaning the internal tubing of the endoscope, medical staff manually clean it with a brush, resulting in high workload, time-consuming and labor-intensive processes. With technological advancements, existing endoscope cleaning equipment has emerged to replace manual cleaning, such as the endoscope cleaning device and equipment disclosed in Chinese patent document CN202211405676.X. The aforementioned existing technology can achieve automated endoscope cleaning.

[0004] Endoscopes have multiple flexible tubes. After cleaning one of the tubes with a brush, the brush needs to be retracted and moved to another tube. During this process, it is necessary to know whether the brush has been retracted and whether it has been ejected again. Currently, existing endoscope cleaning equipment requires manual intervention to make judgments in the above process.

[0005] In addition, clinical practice has shown that it is also necessary to monitor the conveying distance of the brushes delivered by the endoscope cleaning equipment in order to determine whether the brushes slip during delivery. This helps to determine whether the endoscope tubing is blocked and allows for targeted cleaning of the blocked areas. Summary of the Invention

[0006] The main objective of this invention is to provide an endoscope cleaning and disinfection machine to at least partially address the shortcomings of the prior art.

[0007] To achieve the above-mentioned main objectives, the present invention discloses an endoscope cleaning and disinfection machine, comprising:

[0010] The piping system, located inside the cabinet, is used to supply cleaning fluid to at least the cleaning basin;

[0011] A cleaning device, set in a cleaning basin, is used to deliver cleaning brushes to the endoscope to clean the endoscope's tubing.

[0012] The cleaning device includes a winding section, a conveying section, and a detection component. The conveying section is used for outputting and retracting the brushes, and the winding section is used to store the brushes in a winding manner and work in conjunction with the conveying section to output and retract the brushes. The detection component includes a first detection component and a second detection component. The first detection component is located on the brush output side of the conveying section and is used to detect whether the brushes are being conveyed normally. The second detection component is located on the brush input side of the conveying section and is used to detect the conveying distance of the brushes.

[0013] According to a specific embodiment of the present invention, the first detection part includes a detection table, a detection component, a trigger component, and a component to be detected that is linked with the trigger component. The trigger component is movably mounted on the detection table and has an initial position and a detection position. The detection component is mounted on the detection table and corresponds to the component to be detected. The detection table is provided with a channel, and the trigger component can contact a brush passing through the channel and be pushed away from the initial position to the detection position by the brush, thereby driving the component to be detected to generate a follow-up movement to change the detection signal of the detection component.

[0014] According to a specific embodiment of the present invention, the detection platform is provided with a swing shaft orthogonal to the brush conveying direction, and the swing shaft is located on the first side of the channel; wherein, the triggering member is fixedly disposed on the swing shaft, and when the triggering member is in the initial position, it is perpendicular to the channel and can switch to the detection position as the swing shaft swings forward or backward.

[0015] According to a specific embodiment of the present invention, a floating component is provided on the detection table. The floating component is used to keep the triggering component in the initial position when there is no brush conveying in the channel, and can be pushed away to the detection position when the brush is conveyed in the forward and reverse directions.

[0016] The floating assembly includes a floating member and two floating elastic elements, which act on opposite sides of the floating member to maintain its balance.

[0017] The swing shaft is provided with a gear section, and the floating member is provided with a rack section that meshes with the gear section; wherein, under the synergistic action of the two floating elastic members, the floating member can drive the swing shaft to rotate through the rack section and the gear section, so that the triggering member has a tendency to switch from the detection position to the initial position.

[0018] According to one specific embodiment of the present invention, the second detection part includes a transmission roller and a detection component corresponding to the transmission roller. The transmission roller is disposed on the brush conveying path and rotates as the brush is conveyed. The detection component includes a sensor disposed at the transmission roller, which is used to detect the number of rotations of the transmission roller.

[0019] According to one specific embodiment of the present invention, the conveying part includes a conveying base, a support wheel assembly, a pressure wheel assembly, and a self-locking assembly;

[0020] The support wheel assembly includes at least one support wheel disposed on the conveyor base;

[0021] The clamping roller assembly includes a floating clamping seat and at least one clamping roller disposed on the floating clamping seat; the floating clamping seat is disposed on the conveying base and has a disengaged position and a clamping position, when the floating clamping seat is in the clamping position, the clamping roller and the support roller clamp the brush passing between them to convey the brush;

[0022] The self-locking assembly is used to lock the floating clamping seat in the clamping position to maintain continuous feeding of the brush.

[0023] According to one specific embodiment of the present invention, the self-locking assembly includes an actuating shaft, a driving cam, and a locking member;

[0024] The actuating shaft is rotatably mounted on the conveying base and extends in a direction parallel to the brush conveying direction. The driving cam is mounted on the actuating shaft and abuts against the top of the floating clamping seat. When the actuating shaft rotates, the driving cam can press the floating clamping seat down to the clamping position, and the position of the actuating shaft can be locked by the locking member.

[0025] According to a specific embodiment of the present invention, a hinge shaft is provided on the conveying base, the hinge shaft is parallel to the actuating shaft, and the middle part of the locking member is connected to the hinge shaft; wherein, the actuating shaft is provided with a notch, and the locking member is provided with a locking part. When the actuating shaft drives the driving cam to move the floating pressing seat to the pressing position, the notch is exposed and can cooperate with the locking part to be locked in the current position.

[0026] According to a specific embodiment of the present invention, the winding portion includes a winding base, a winding reel, and a rotating member. The brush is wound on the winding reel, and the winding reel is disposed on the rotating member and can rotate relative to the rotating member. The winding reel is provided with a connecting member, which has a first position separated from the rotating member and a second position engaged with the rotating member. When the connecting member is in the first position and separated from the rotating member, the brush can be conveyed forward under the drive of the conveying portion while the brush drives the winding reel to adaptively rotate in the forward direction and be continuously released. When the connecting member is in the second position and engaged with the rotating member, the winding reel can be directly driven by the rotating member to rotate in the reverse direction, so that the brush is continuously wound up.

[0027] According to a specific embodiment of the present invention, the engaging member switches between a first position and a second position in a rotating manner; wherein, the rotating member is provided with connecting teeth, the connecting teeth being outer peripheral gears arranged in the circumferential direction of the rotating member, and the engaging member is disposed on the outside of the connecting teeth in a radially inclined manner relative to the connecting teeth; during the release of the brush, the engaging part on the engaging member can automatically disengage from the connecting teeth and rotate under the push of the connecting teeth, so that the engaging member automatically switches to the first position.

[0028] The present invention has the following beneficial effects: It provides an endoscope cleaning and disinfection machine, which detects whether the brush is being transported normally by a first detection part set on the brush output side of the conveying section, and detects the conveying distance of the brush by a second detection part set on the brush input side of the conveying section, thereby realizing real-time detection of the brush conveying status and conveying distance. The above detection process is carried out synchronously during the brush conveying process, which has the advantages of being simple, efficient and accurate in detection results.

[0029] To more clearly illustrate the purpose, technical solution, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0054] Many specific details are set forth in the following description in conjunction with embodiments in order to provide a full understanding of the invention. However, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of the invention.

[0055] The endoscope cleaning and disinfection machine of this invention embodiment is as follows: Figure 1-2As shown, it includes a cabinet 10, a cleaning basin 20, a piping system, and a cleaning device 30. The cleaning basin 20 is mounted on the cabinet 10, preferably at the top, and is used to hold the endoscope to be cleaned. The cabinet 10 has an openable top cover 11 that covers the cleaning basin 20. The piping system is located inside the cabinet 10 and supplies cleaning fluid, disinfectant, drying gas, etc., to the cleaning basin 20. The cleaning device 30 is located in the cleaning basin 20 and delivers brushes A to the endoscope for automatic cleaning of the endoscope's tubing. In this embodiment, the cleaning basin 20 can be square or have other structures adapted to the shape of the endoscope. The piping system has multiple outlets 12 extending into the cleaning basin 20 to directly supply cleaning fluid, disinfectant, etc., to the cleaning basin 20.

[0056] like Figure 3-4 As shown, the cleaning device 30 includes a housing 31, a winding section 32, a conveying section 33, and a detection section 34; wherein, the conveying section 33 is used for outputting and retracting the brush A, the winding section 32 is used to receive the brush A in a winding manner and cooperate with the conveying section 33 to output and retract the brush A, and the detection section 34 is used to detect whether the brush A is being conveyed normally and to detect the conveying distance of the brush A.

[0057] The endoscope has three internal tubings. To automatically clean each of the three tubings without disassembly, the output position of brush A in this embodiment is switchable. Specifically, the housing 31 is equipped with a switching mechanism 35 and three cable outlet conduits 311, each corresponding to one of the three internal tubings of the endoscope. The delivery section 33 is mounted on the switching mechanism 35 and switches between the positions corresponding to the three internal tubings under the drive of the switching mechanism 35. The switching mechanism 35 can switch in various ways, including sliding, swinging, and multi-axis motion. For example,... Figure 3-4 The swing pattern shown.

[0058] like Figure 5-6 As shown, the conveying section 33 includes a conveying base 331, a support wheel assembly 332, a pressure wheel assembly 333, and a self-locking assembly 334. The conveying base 331 is mounted on the housing 31 to provide installation space for the support wheel assembly 332, the pressure wheel assembly 333, and the self-locking assembly 334. The conveying base 331 is provided with a conveying channel 335 for the brush A to pass through. The conveying channel 335 is used to provide conveying guidance for the brush A to prevent the brush from deviating during the conveying process.

[0059] 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 located on opposite sides of the brush A, specifically, for example, on the upper and lower sides. The support wheel 3321 is preferably fixed in the height direction and can rotate under the drive of the conveying drive assembly to convey the brush A. 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. Thus, the conveying of the brush A can be achieved by the rotation of the support wheel 3321.

[0060] like Figure 7-8 As shown, the clamping wheel assembly 333 also includes a floating clamping seat 3332, a guide rod 3333, and a return spring. Preferably, there are multiple guide rods 3333. The floating clamping seat 3332 is disposed on the guide rod 3333 and can move relative to the guide rod 3333 from a disengaged position to a clamping position, while simultaneously squeezing the return spring. The clamping wheel 3331 is rotatably mounted on the floating clamping seat 3332 and moves toward and away from the support wheel 3321 as the floating clamping seat 3332 moves.

[0061] When the floating clamping seat 3332 is in the clamping position, its position can be locked by the self-locking component 334 to maintain continuous feeding of the brush. Please continue reading Figure 7-8 The self-locking assembly 334 includes a toggle shaft 3341, a drive cam 3342, and a locking member 3343. The toggle shaft 3341 is arranged in a direction parallel to the conveying channel 335. The drive cam 3342 is arranged on the toggle shaft 3341, and the locking member 3343 is arranged on the upper base plate 3311 of the conveying base 331. Preferably, one end of the toggle shaft 3341 is provided with a handle 3344. By manually rotating the handle 3344, the toggle shaft 3341 is driven to rotate to change the position of the drive cam 3342. The drive cam 3342 then acts on the floating pressure seat 3332, specifically on the top of the floating pressure seat 3332, so that the floating pressure seat 3332 switches between a disengaged position and a pressed position.

[0062] like Figure 9-10 As shown, the actuating shaft 3341 is provided with a notch 3345, and the locking member 3343 is provided with a locking part 3346 that is adapted to the notch 3345. When the actuating shaft 3341 rotates to drive the driving cam 3342 to drive the floating pressure seat 3332 to the pressing position, the notch 3345 is exposed and can cooperate with the locking part 3346 on the locking member 3343. The locking part 3346 locks the actuating shaft 3341 in the current position and prevents it from rotating.

[0063] Furthermore, the upper base plate 3311 is provided with a hinge shaft 3312 parallel to the actuating shaft 3341. The middle part of the locking member 3343 is connected to the hinge shaft 3312 and can rotate relative to the hinge shaft 3312. The locking part 3346 is provided on the side of the hinge shaft 3312 near the actuating shaft 3341. For ease of operation, a lifting spring 3347 is provided on the upper base plate 3311. The lifting spring 3347 contacts the side of the locking member 3343 away from the actuating shaft 3341 and drives it to rise, so that the locking part 3346 always has a downward pressing tendency. When the actuating shaft 3341 rotates to the point where the notch 3345 is exposed, the locking part 3346 can automatically press down under the drive of the lifting spring 3347 and form a cooperation with the notch 3345.

[0064] Please refer to it again. Figure 6 A limiting portion 3313 is preferably provided on the upper substrate 3311 near the grip 3344. The limiting portion 3313 is used to limit the maximum angle of forward rotation of the actuating shaft 3341, at which the notch portion 3345 can be exposed. For example, the notch portion 3345 is an L-shaped groove facing the locking portion 3346, and the locking portion 3346 is a protrusion adapted to the notch portion 3345. When the actuating shaft 3341 rotates to the point where the notch portion 3345 is exposed, the locking portion 3346 abuts against the side wall of the notch portion 3345 facing the hinge shaft 3312 and limits the reverse rotation of the actuating shaft 3341, thereby locking the position of the actuating shaft 3341 and the drive cam 3342.

[0065] When it is necessary to unlock, press the locking member 3343 away from the actuating shaft 3341 under the action of external force. At this time, the restriction effect of the locking part 3346 on the notch part 3345 disappears. Manually rotate the actuating shaft 3341 in the opposite direction and drive the drive cam 3342 to rotate. The return spring can realize the automatic lifting of the floating pressure seat 3332 and switch to the disengaged position.

[0066] In this embodiment, there are two support wheels 3321 and two pressure wheels 3331. The two pairs of support wheels 3321 and pressure wheels 3331 are located at the entrance and exit of the conveying channel 335, respectively. In other embodiments, the conveying channel 335 may be provided in multiple sections, and the number of support wheels 3321 and pressure wheels 3331 may be, for example, three, four or even more. This is not limited here and will not be discussed further.

[0067] For example, the multiple support wheels 3321 are driven by a synchronous belt and a tensioner to ensure synchronous rotation. Further, one of the support wheels 3321 preferably has an input gear 336, and the conveyor base 331 also has a conveyor motor and a transmission gear assembly to transmit power to the input gear. Preferably, the input gear 336 is a bevel gear to save space in the drive structure, making the structure more compact.

[0068] The detection section 34 is installed on the conveying section 33 and is used to detect the conveying of brush A. The detection section 34 mainly includes a first detection section 34a and a second detection section 34b. The first detection section 34a is installed on the output side of brush A in the conveying section 33 to detect whether brush A is being conveyed normally, that is, to detect whether brush A is being conveyed normally, especially after switching between multiple positions of different conduits. The second detection section 34b is installed on the input side of brush A in the conveying section 33 to detect the conveying distance of brush A, and to determine whether the endoscope tubing is blocked based on the detection results, so as to carry out key cleaning of the blocked area.

[0069] like Figure 11-16 As shown, the first detection part 34a includes a detection table 341, a detection component 342, a trigger component 343, and a detected component 344 that is linked with the trigger component 343. The trigger component 343 is movably installed on the detection table 341 and has an initial position and two detection positions. The detection component 342 is installed on the detection table 341 and corresponds to the detected component 344. The detection table 341 is provided with a channel 3411. The trigger component 343 can contact a brush A that passes through the channel 3411 and be pushed away from the initial position to the detection position by the brush A, thereby driving the detected component 344 to generate a follow-up movement to change the detection signal of the detection component 342.

[0070] For example, when the trigger member 343 is in the initial position, the detected member 344 can be detected by the detection member 342 and emit a first signal; when the trigger member 343 moves to a non-initial position, the detected member 344 cannot be detected by the detection member 342 and emit a second signal; therefore, the trigger member 343 may have multiple detection positions that prevent the detected member 344 from being detected by the detection member 342. In this way, whether the brush A is being conveyed in the forward or reverse direction, as long as the trigger member 343 is pushed away from the initial position during the conveying process of the brush A, the detection of whether the brush A is being conveyed normally can be achieved.

[0071] Furthermore, the detection table 341 is provided with a swing shaft 345 orthogonal to the conveying direction of brush A, and the swing shaft 345 is located on the first side of the channel 3411; the trigger member 343 is fixedly mounted on the swing shaft 345. When the trigger member 343 is in the initial position, it is perpendicular to the conveying direction of the channel 3411 and can switch to the detection position as the swing shaft 345 swings forward or backward. Preferably, the connection between the swing shaft 345 and the detection table 341 is provided with a bearing or adopts a low-friction fit, so as to smoothly drive the trigger member 343 and the swing shaft 345 to swing during the conveying of brush A, and also to help ensure that the trigger member 343 does not or nearly does not affect the conveying of brush A.

[0072] To maintain the automatic switching of the triggering component 343, a floating component 346 is provided on the detection table 341 in this embodiment. The floating component 346 is used to keep the triggering component 343 in its initial position when there is no brush A being conveyed in the channel 3411, and can be pushed away to the detection position when the brush A is conveyed in both the forward and reverse directions. Please continue. Figure 13-16 The floating assembly 346 includes a floating member 3461 and two floating elastic elements 3462. The two floating elastic elements 3462 act on opposite sides of the floating member 3461 to maintain the balance of the floating member 3461. Specifically, the floating elastic element 3462 is a straight spring, with one end connected to the floating member 3461 and the other end connected to the detection table 341; wherein the two straight springs are aligned with each other in the length direction. Preferably, the two floating elastic elements 3462 are of the same specification.

[0073] The swing shaft 345 is equipped with a gear portion 3451, and the floating member 3461 is equipped with a rack portion 3463 that meshes with the gear portion 3451. Under the synergistic action of the two floating elastic members 3462, the floating member 3461 can drive the swing shaft 345 to rotate through the rack portion 3463 and the gear portion 3451, thereby causing the trigger member 343 to have a tendency to switch from the detection position to the initial position. In this embodiment, the floating component 346 uses a force balance method to control the position of the trigger member 343 through the rack portion 3463 on the floating member 3461 and the gear portion 3451 on the swing shaft 345, which is appropriately adapted to the detection of the brush A that needs to be conveyed in both directions.

[0074] Please continue reading. Figure 11-12The detection table 341 is provided with a pushing member 3412, which is located on the second side of the channel 3411 and corresponds to the trigger member 343. When the brush A passes between the pushing member 3412 and the trigger member 343, it can be restricted by the pushing member 3412, which drives the trigger member 343 to be pushed away from the initial position to the detection position. Further, the detection table 341 is provided with a pushing elastic member 3413, which is used to make the pushing member 3412 have a tendency to move towards the contact member. When the brush A passes between the pushing member 3412 and the trigger member 343, the pushing elastic member 3413 is compressed.

[0075] The pushing member 3412 has a guide surface facing the trigger member 343. When the brush A passes between the pushing member 3412 and the trigger member 343, it can be guided by the guide surface to move towards the side closer to the trigger member 343. Preferably, the guide surface is an arc-shaped guide surface to facilitate the smooth transport of the brush A between the pushing member 3412 and the trigger member 343.

[0076] like Figure 17-18 As shown, the second detection part 34b includes a transmission roller 347 and a detection component corresponding to the transmission roller 347. The transmission roller 347 is disposed on the conveying path of the brush A and rotates as the brush A is conveyed. The detection component includes a sensor 348 disposed on the transmission roller 347. The sensor 348 is used to detect the number of rotations of the transmission roller 347. For example, the sensor 348 is a Hall sensor.

[0077] The transmission roller 347 is preferably mounted on the conveying base 331 via a bearing. 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.

[0078] To maintain synchronized movement between drive roller 347 and brush A, please refer to [further details]. Figure 18 The second detection section also includes a pressing roller 349, which and the transmission roller 347 are located on opposite sides of the brush A. The pressing roller 349 rotates as the brush A is conveyed, simultaneously pressing the brush A against the transmission roller 347 to prevent relative displacement between the brush A and the transmission roller 347. Preferably, the pressing roller 349 is mounted on the floating pressing seat 3332 via a connecting block 3491, and can be raised and lowered along with the floating pressing seat 3332.

[0079] Preferably, at least one of the drive roller 347 and the pressing roller 349 is provided with a flexible sleeve capable of deformation; wherein, the drive roller 347 is preferably provided with a flexible sleeve, which can increase the contact area and friction between the drive roller 347 and the brush A; in the embodiment, under the action of the pressing roller 349, the brush A can be pressed onto the drive roller 347. As the brush A is conveyed, the drive roller 347 generates a corresponding rotation, and the number of rotations of the drive roller 347 is detected by the detection component. The actual distance of the brush A conveyed can be accurately calculated based on the diameter of the drive roller 347. When a blockage occurs or the conveying of the brush A is not smooth, the conveying of the brush A slows down. At this time, the brush A can be conveyed in the opposite direction to the aforementioned conveying direction for a set distance, for example, 20cm, and recorded by the detection component; then, it can be conveyed again in the aforementioned conveying direction for secondary cleaning. Repeating the above process can perform multiple cleanings at the same location.

[0080] like Figure 19-22 As shown, the winding portion 32 in this embodiment includes a winding base 321, a winding reel 322, and a rotating member 323. The winding base 321 is mounted on the housing 31, and the brush A is wound and housed on the winding reel 322. The winding reel 322 is disposed on the rotating member 323 and can rotate relative to the rotating member 323. The winding reel 322 is provided with a connecting member 324, which has a first position separate from the rotating member 323 and a second position engaged with the rotating member 323.

[0081] When the engaging member 324 is in the first position and separated from the rotating member 323, the brush A can be conveyed forward under the drive of the conveying section 33, while the brush A drives the winding reel 322 to adaptively rotate in the forward direction and be continuously released. When the engaging member 324 is in the second position and engaged with the rotating member 323, the winding reel 322 can be directly driven by the rotating member 323 to rotate in the reverse direction, so that the brush A is continuously wound up. In this embodiment, the winding reel 322 is engaged or separated from the rotating member 323 by the engaging member 324. When separated, the winding reel 322 can achieve unpowered rotation to adaptively release the brush A. When engaged, the rotation of the rotating member 323 drives the winding reel 322 to wind up the brush A.

[0082] During the brush winding process, the rate at which the brush is wound by the rotation of the rotating component 323 is preferably slightly greater than the conveying rate of the conveying section 33, thereby keeping the brush wound in a taut state.

[0083] like Figure 21-22As shown, the rotating member 323 is provided with a connecting tooth 3231, and the engaging member 324 is provided with an engaging portion 3241 corresponding to the connecting tooth 3231. When the engaging member 324 is in the second position, the engaging portion 3241 can abut against the connecting tooth 3231, so that the winding reel 322 rotates synchronously with the rotating member 323. Preferably, the winding reel 322 is provided with an engaging elastic member 325, which is used to maintain the engaging member 324's tendency to switch from the first position to the second position, so as to limit the winding reel 322 from rotating in the opposite direction during the release of the brush A.

[0084] In this embodiment, the engaging member 324 switches between a first position and a second position by rotation; the engaging member 324 is preferably a rocker arm structure, and the engaging portion 3241 is specifically one end of the engaging member 324; wherein, the connecting tooth 3231 is specifically an outer peripheral gear arranged in the circumferential direction of the rotating member 323, and the engaging member 324 is arranged on the outside of the connecting tooth 3231 in a radially inclined manner relative to the connecting tooth 3231; during the release of the brush A, the engaging portion 3241 can automatically disengage from the connecting tooth 3231 and rotate under the push of the connecting tooth 3231, so that the engaging member 324 automatically switches to the first position.

[0085] like Figure 23-24 As shown, the winding reel 322 has an inner cavity 322a, and the rotating component 323 is disposed in the inner cavity 322a; wherein, a rotating connector 326 is provided at the connection between the winding reel 322 and the rotating component 323, and the rotating connector 326 is, for example, a bearing or other low-friction component.

[0086] For example, the rotating component 323 includes a first rotating body 323a, a second rotating body 323b, and an intermediate connecting body 323c for connecting the first rotating body 323a and the second rotating body 323b; a winding base 321 is provided with a winding drive assembly 327, which drives the first rotating body 323a to rotate, and the second rotating body 323b is connected to the winding reel 322 through a rotating connector 326. A waterproof baffle 328 is provided in the inner cavity 322a and is fixedly connected to the winding reel 322. The waterproof baffle 328 is rotatably connected to the intermediate connecting body 323c to form an installation space in the inner cavity 322a, and the connecting component 324 is located within the installation space.

[0087] For example, the winding drive assembly 327 includes a main drive shaft 3271, a gear disk 3272, and a gear ring 3273. The main drive shaft 3271 is rotatably supported on the base plate 3211 of the winding base 321. The gear disk 3272 is fixedly mounted on the main drive shaft 3271, and the gear ring 3273 is fixedly mounted on the first rotating body 323a and meshes with the gear disk 3272. In the embodiment, the diameter of the gear disk 3272 is preferably close to the diameter of the winding disk 322 or the difference between the two is small. The main purpose of this setting is to ensure the coaxiality of the rotational movement of the winding disk 322 by using the gear disk 3272, which is beneficial to the conveying of the brush A.

[0088] The winding base 321 is preferably bowl-shaped, and the winding spool 322 is at least partially located inside the winding base 321; the base plate 3211 of the winding base 321 has perforations through which cleaning water can be discharged to the outside of the winding base 321. Please continue reading Figure 24 A sealing ring 329 is provided at the connection between the intermediate connector 323c and the waterproof baffle 328. The sealing ring 329 can restrict the cleaning water from entering the installation space, thereby waterproofing the components in the installation space.

[0089] The cabinet 10 in this embodiment is also equipped with a control module. The control module performs intelligent cleaning control of the endoscope according to the pre-set control instructions, including but not limited to the delivery control of brush A, the supply control of cleaning fluid and disinfectant, and fault alarms, etc. It can realize automatic cleaning without human intervention, effectively avoid the occurrence of faults, and has the advantages of saving time and effort and being highly practical.
