Its technical solution includes a tank storage cabin, a washing cabin and a packaging cabin arranged in sequence in the horizontal direction and a control system. The washing cabin is respectively connected to the tank storage cabin and the packaging cabin. The tank storage cabin is provided with at least a cleaning tank, a multi-enzyme washing tank, a disinfection tank and a drying tank. The control system is used to control the cleaning tank, the multi-enzyme washing tank, the disinfection tank and the drying tank to move to the washing position of the washing cabin in time. A robotic arm is provided at the upper position in the washing cabin. The robotic arm is used to clamp the endoscope and put it into or take it out of the cleaning tank, the multi-enzyme washing tank or the disinfection tank or the drying tank, and can move the endoscope to the packaging cabin.

[0005] The technical solutions disclosed in the above patent documents can realize automatic cleaning of flexible endoscopes, but in terms of specific structure, multiple bins or tanks are required as working spaces for different cleaning processes of flexible endoscopes, which increases the space occupied by the equipment and complicates the overall structure of the equipment, which is not conducive to reducing the production cost of the cleaning equipment and simplifying the cleaning process of the flexible endoscope. In addition, when the flexible endoscope is placed in the cleaning equipment described in the above patent for cleaning and disinfection, the flexible endoscope needs to be bent and coiled, and more parts of the flexible endoscope are pressed against each other, which will lead to an increase in cleaning dead angles, thereby affecting the cleaning effect of the flexible endoscope; although the purpose of eliminating cleaning dead angles can be achieved by changing the placement posture and performing multiple cleanings, it will undoubtedly lead to an extension of the cleaning cycle and an increase in cleaning costs.

[0033] Specifically, Figure 2 As shown, the cleaning and disinfection tank 300 used in the present invention is divided into a placement area 310 and a flushing area 320, and the placement area 310 and the flushing area 320 are functional divisions; in order to make the structural division clear, it can also be achieved by setting a lower height partition between the placement area 310 and the flushing area 320, but the placement area 310 and the flushing area 320 are essentially two connected areas in the cleaning and disinfection tank 300. The placement area 310 is used to place the flexible endoscope 900 at the beginning of the cleaning work, and the flushing area 920 is used to disinfect, flush, and scrub the insertion part 920 of the stretched flexible endoscope 900 in the subsequent steps of the cleaning work. A perfusion joint 311 is arranged on the wall of the cleaning and disinfection tank 300 located in the placement area 310. The perfusion joint 311 is used to connect with the perfusion port on the joint part 910 of the flexible endoscope 900. The number of perfusion joints 311 is set according to the number of perfusion ports on the joint part 910; the perfusion joint 311 is connected with the water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 fixed inside the cabinet 100 through a pipeline, and the connecting pipeline of the perfusion joint 311 is connected with the water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 through a multi-way joint and a branch pipeline. A control valve is arranged at the multi-way joint to control the flow channel and flow rate. The water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 are equipped with a liquid pump to provide power for liquid output; the flexible endoscope 900 is fully perfused through the perfusion joint 311. A brush joint 321 is provided on the groove wall of the cleaning and disinfection groove 300 located in the flushing area 320. The brush joint 321 is used to connect with the irrigation port of the joint part 910 of the flexible endoscope 900. A brush head 322 is also provided in the brush joint 321. The brush head 322 is a retractable brush head. After the irrigation port of the joint part 910 of the flexible endoscope 900 is connected with the brush joint 321, the brush head 322 can be extended to pass through the irrigation port into the interior of the insertion part 920 by extending the brush head 322, and the internal pipeline of the insertion part 920 can be cleaned by brushing.

[0034] like Figure 2As shown, a liquid injection port 330, a liquid discharge port 340 and a flushing nozzle 350 are arranged on the tank wall of the cleaning and disinfection tank 300; the liquid injection port 330 and the flushing nozzle 350 are arranged on the side wall of the cleaning and disinfection tank 300, and the liquid discharge port 340 is arranged on the bottom wall of the cleaning and disinfection tank 300. The liquid injection port 330 and the flushing nozzle 350 are connected to the water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 fixed inside the cabinet 100 through a pipeline, and the corresponding connecting pipelines of the liquid injection port 330 and the flushing nozzle 350 are connected to the water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 through a multi-way joint and a branch pipe, and a control valve is arranged at the multi-way joint to switch the flow channel and control the flow rate. At least one liquid injection port 330 is arranged, and the liquid injection port 330 is used to inject cleaning water, disinfectant or multi-enzyme liquid into the cleaning and disinfection tank 300 to soak and clean the flexible endoscope 900 placed in the cleaning and disinfection tank 300. A plurality of flushing nozzles 350 are required to be provided, and the outside of the flexible endoscope 900 is flushed by spraying cleaning water, disinfectant or multi-enzyme liquid. The flushing nozzle 350 adopts a rotatable nozzle to increase the coverage of the flushing work of the flushing nozzle 350; the flushing water volume and flushing water pressure of the flushing nozzle 350 are controlled by the cooperation of the liquid pump and the control unit 200. The drain port 340 is connected to the drain pipe arranged inside the cabinet 100, and the liquid in the cleaning and disinfection tank 300 can be discharged through the drain port 340 and the drain pipe after the cleaning is completed; the drain port 340 is an openable and closable structure, which is kept closed during the cleaning process of the flexible endoscope 900, and is opened for drainage only after the cleaning is completed.

[0035] The present invention can stretch the insertion portion 920 of the flexible endoscope 900 so that the insertion portion 920 of the flexible endoscope 900 is kept in a straight state for flushing. The stretching of the flexible endoscope 900 is achieved by the cooperation of the bracket, the clamping component 700 and the brushing connector 321. Figure 2As shown, a plurality of brackets are provided in the cleaning and disinfection tank 300, and the brackets include a positioning bracket 610 and a flushing bracket 620. The positioning bracket 610 is used to position the flexible endoscope 900 placed in the cleaning and disinfection tank 300 after the perfusion work is completed, and the part where the insertion part 920 of the flexible endoscope 900 and the joint part 910 are connected is placed on the positioning bracket 610 as a starting point for stretching the insertion part 920; the flushing bracket 620 is used to support the insertion part 920 of the flexible endoscope 900 after stretching. Only one positioning bracket 610 is required, while multiple flushing brackets 620 need to be provided; the positioning bracket 610 is provided between the placement area 310 and the flushing area 320 of the cleaning and disinfection tank 300, and all the flushing brackets 620 are provided in the flushing area 320 of the cleaning and disinfection tank 300, and multiple flushing brackets 620 are evenly spaced and arranged in the flushing area 320 along the axis between the perfusion joint 311 and the scrubbing joint 321; the perfusion joint 311 and the scrubbing joint 321 are axially aligned to ensure that the insertion portion 920 of the flexible endoscope 900 remains straight after stretching. The clamping component 700 is used to stretch the insertion portion 920 of the flexible endoscope 900, and the joint portion 910 of the flexible endoscope 900 is clamped by the clamping component 700, and then the clamping component 700 pulls the joint portion 910 toward the scrubbing joint 321 until the insertion portion 920 is straightened and the perfusion port of the joint portion 910 is docked with the scrubbing joint 321. The present invention stretches the insertion portion 920 of the flexible endoscope 900 so that the insertion portion 920 of the flexible endoscope 900 remains straight during the cleaning process, thereby avoiding the problem of dead angles during cleaning caused by placing the flexible endoscope 900 in a spiral position, thereby effectively improving the cleaning effect of the flexible endoscope 900.

[0036] During the process of the clamping component 700 stretching the insertion part 920, the bracket can be lowered to a certain height to leave space for the movement of the insertion part 920. The clamping component 700 can adopt a mature mechanical arm in the prior art, which has high flexibility and strong controllability; the operation of the mechanical arm is controlled by the control unit 200. The mechanical arm can be installed on the side wall of the cleaning and disinfection tank 300, and the installation height should be higher than the liquid injection port 330 and the flushing nozzle 350, and also higher than the liquid level in the cleaning and disinfection tank 300.

[0037] The lifting and lowering of the bracket can be achieved by pneumatic drive, hydraulic drive, gear drive, etc. Figure 2 , Figures 6 to 8As shown, the present invention adopts a lifting drive mechanism to realize the lifting of the bracket by pneumatic drive. A pressurized gas source 630 is fixed inside the cabinet 100, and the pressurized gas source 630 is located below the cleaning and disinfection tank 300. A plurality of driving cylinders 640 are arranged on the pressurized gas source 630, and the driving cylinders 640 and the brackets are in a one-to-one correspondence relationship; at the same time, a plurality of bracket holes are arranged at the bottom of the cleaning and disinfection tank 300, and the bracket holes and the brackets are also in a one-to-one correspondence relationship. The bottom of the bracket is connected to the output end of the corresponding driving cylinder 640, and the upper part of the bracket extends into the cleaning and disinfection tank 300 after passing through the corresponding bracket hole upward. The work of the pressurized gas source 630 and the driving cylinder 640 is controlled by the control unit 200; under the control of the control unit 200, the lifting and lowering actions of each bracket can be performed independently or synchronously. Due to the use of a liftable bracket, after the insertion part 920 of the flexible endoscope 900 is stretched and supported by the bracket, the bracket supporting the insertion part 920 can be raised and lowered during the process of stretching and cleaning the insertion part 920. A part of the bracket is used to support the insertion part 920, and after cleaning for a period of time, another part of the bracket is raised to support different parts of the insertion part 920, and the previously supporting bracket is lowered, so that the part of the insertion part 920 supported by the bracket can be cleaned, further avoiding cleaning dead corners.

[0038] Furthermore, in order to ensure the sealing of the bottom of the cleaning and disinfection tank 300 while achieving the lifting action of the bracket, as Figure 2 , Figures 6 to 8 As shown, the present invention provides a sealing cover 650 on the bracket. A sealing cover 650 is provided on each bracket, and the sealing cover 650 is a flexible waterproof sealing cover with a small upper end and a large lower end. The upper and lower ends of the sealing cover 650 are provided with openings. The lower end opening of the sealing cover 650 is connected to the orifice of the corresponding bracket hole to form a sealing fit, and the upper end opening of the sealing cover 650 is sleeved and connected to the corresponding bracket to form a sealing fit. The sealing cover 650 can be made of a rubber material with good elasticity, and is connected and fixed to the orifice of the bracket hole and the peripheral surface of the bracket by bonding. In the process of lifting and lowering the bracket, the sealing cover 650 can adapt to the lifting and lowering action of the bracket through its own deformation, and ensure the sealing of the bracket hole.

[0039] In order to ensure that the positioning bracket 610 forms a stable positioning for the insertion portion 920 of the flexible endoscope 900, to prevent the insertion portion 920 of the flexible endoscope 900 from retracting when placed on the positioning bracket 610, and to enable the clamping component 700 to accurately grasp and clamp the joint portion 910 of the flexible endoscope 900, the present invention further optimizes the structure of the positioning bracket 610. Figure 6 and Figure 7As shown, the present invention is provided with a non-return assembly at the top of the positioning bracket 610, and the non-return assembly includes two bristle rollers, and the bristle rollers are cylindrical structures with soft bristles covered on the surface, and the two bristle rollers are arranged at intervals in the height direction of the positioning bracket 610, and the bristle roller located at the bottom is the lower bristle roller 611, and the bristle roller located at the top is the upper bristle roller 612; two support rods are vertically fixed on the top of the positioning bracket 610, and the lower bristle roller 611 and the upper bristle roller 612 are rotatably matched with the support rods through a rotating shaft, and the vertical spacing between the lower bristle roller 611 and the upper bristle roller 612 is not less than the outer diameter of the insertion portion 920. When the insertion part 920 of the flexible endoscope 900 is positioned by the positioning bracket 610, the end of the insertion part 920 is passed between the lower bristle roller 611 and the upper bristle roller 612, and the insertion part 920 is clamped by the lower bristle roller 611 and the upper bristle roller 612; at the same time, when the clamping part 700 clamps the joint part 910 to stretch the insertion part 920, a rolling fit is formed between the insertion part 920 and the lower bristle roller 611 and the upper bristle roller 612, which will not affect the movement of the insertion part 920, and the soft bristles on the surface of the bristle roller can clean the surface of the insertion part 920 by rolling the bristle roller during the stretching process.

[0040] Furthermore, in order to make the two bristle rollers have a better fit with the surface of the insertion part 920, the present invention optimizes the structure of the bristle rollers, and the surfaces of the lower bristle roller 611 and the upper bristle roller 612 are set to radially concave arc surfaces, so that the lower bristle roller 611 and the upper bristle roller 612 form a waist-shaped cylinder structure with an outer diameter gradually increasing from the middle to the two ends, and the arc curvature of the lower bristle roller 611 and the upper bristle roller 612 are adapted to the surface curvature of the insertion part 920; the two bristle rollers can form a better fit with the surface of the insertion part 920, and the soft brush has a better cleaning effect on the insertion part 920. In addition, the present invention also optimizes the arrangement of the soft bristles on the bristle rollers, such as Figure 6 As shown, the soft bristles are arranged obliquely on the surface of the corresponding bristle roller, and the inclination direction of the soft bristles is opposite to the rotation direction of the corresponding bristle roller, that is, the end of the soft bristles that is not connected to the bristle roller is facing away from the stretching direction of the insertion part 920, which can play a non-return role on the insertion part 920 and clean the surface of the insertion part 920 along the stretching direction of the insertion part 920 without damaging the surface of the insertion part 920.

[0041] In addition, the present invention also provides a support pad 621 on the top of the flushing bracket 620. The support pad 621 is a concave arc support pad, and the arc of the support pad 621 matches the surface arc of the insertion part 920. When the flushing bracket 920 supports the stretched insertion part 920, the contact surface of the support pad 621 and the insertion part 920 is more suitable, which can limit the insertion part 920 to prevent the insertion part 920 from being deflected, and can provide a more stable support effect for the insertion part 920, and will not cause damage to the insertion part 920.

[0042] like Figures 2 to 4 As shown, in the present invention, a brush head driving mechanism is provided to drive the brush head 322 to extend and retract. The brush head driving mechanism includes a driving motor 323, a brush head connecting portion 324 and a spiral channel 325. The driving motor 323 and the spiral channel 325 are both fixed in the cabinet 100. There is no direct connection relationship between the spiral channel 325 and the driving motor 323. The spiral channel 325 is a channel structure that spirally extends. The spiral channel 325 is centered on the output end axis of the driving motor 323 and spirally extends from the inside to the outside and communicates with the brushing joint 321 from the inside of the cabinet 100. The brush head connecting portion 324 is a linear structure with certain deformation performance and hardness, for example, a rubber material or a flexible metal material; one end of the brush head connecting portion 324 is wound and fixed on the output end of the driving motor 323, and the other end of the brush head connecting portion 324 passes through the spiral channel 325 and is fixedly connected to the brush head 322. After the driving motor 323 is started, the output end of the driving motor 323 can rotate forward or reverse, so that the brush head connection part 324 is further wound on the output end of the driving motor 323, thereby driving the brush head 322 to retract; or the brush head connection part 324 is loosened on the output end of the driving motor 323. Due to the limiting effect of the spiral channel 325 and the fact that the brush head connection part 324 has a certain hardness, it can only extend outward along the spiral channel 325, thereby driving the brush head 322 to extend. The control unit 200 controls the driving motor 323 to rotate forward or reverse to drive the brush head 322 to extend or retract. After the clamping part 700 stretches the insertion part 920 of the flexible endoscope 900 and clamps the joint part 910 to dock the irrigation port with the brushing joint 321, the brush head 322 can pass through the irrigation port and extend into the interior of the insertion part 920. The interior of the insertion part 920 is scrubbed by the reciprocating motion of the brush head 322 extending and retracting repeatedly.

[0043] like Figure 4As shown, in order to improve the brushing effect of the brush head 322 on the inside of the insertion part 920, the present invention further sets the brush head connection part 324 as a hollow soft hose, for example, a metal hose, so that liquid can be passed into the brush head connection part 324, and one end of the water pipe 360 ​​is connected with the water source pipeline, the disinfectant configuration box 400 and the multi-enzyme liquid configuration box 500 through a multi-way joint, and a control valve is provided at the multi-way joint to control the flow channel and flow rate; the other end of the water pipe 360 ​​is connected with the relay part 326 fixed to the output end of the driving motor 323, and a hollow cavity is provided in the relay part 326. The outer shape structure of the relay part 326 is not limited, and is preferably cylindrical. A joint is provided on the circumferential surface of the relay part 326 to communicate with the brush head connection part 324, and the brush head connection part 324 is wrapped around the relay part 326; as shown Figure 5 As shown, the main body of the brush head 322 is a nozzle head 328, an internal cavity connected to the brush head connection part 324 is arranged inside the nozzle head 328, and a bristle layer 327 is arranged outside the nozzle head 328. The base layer of the bristle layer 327 can be fixed on the nozzle head 328 by snapping or clamping so that the bristle layer 327 can be disassembled, and a plurality of bristles are arranged evenly spaced on the base surface of the bristle layer 327; a plurality of spray holes connected to the internal cavity are arranged on the surface of the nozzle head 328, and a through hole is also arranged on the base layer of the bristle layer 327 to form a communication relationship with the spray holes. When it is necessary to brush the inside of the insertion part 920 to improve the cleaning effect, the bristle layer 327 can be installed on the nozzle head 328; when it is only necessary to rinse the inside of the insertion part 920 to avoid the bristles from damaging the inside of the insertion part 920, the bristle layer 327 can be removed from the nozzle head 328. Through the above structure, the liquid can flow into the relay part 326 through the water pipe 360, then flow into the brush head connecting part 324 through the joint, and finally be sent to the nozzle part 328 through the brush head connecting part 324. When the brush head 322 brushes the inside of the insertion part 920, water is sprayed outward through the spray hole, and the brush bristle layer 327 cooperates to realize the brushing of the inside of the insertion part 920.

[0044] Since the relay part 326 is fixedly arranged at the output end of the driving motor 323, the relay part 326 rotates under the drive of the driving motor 323. If the water pipe 360 ​​and the relay part 326 are relatively fixed, it is easy to cause the water pipe 360 ​​to be damaged due to repeated twisting. The present invention further improves the connection structure between the water pipe 360 ​​and the relay part 326; Figure 4As shown, the water pipe 360 ​​and the relay part 326 form a rotatable fit through the relay bearing 329, the outer ring of the relay bearing 329 is fixedly connected to the relay part 326, the inner ring of the relay bearing 329 is fixedly connected to the end of the water pipe 360, and the relay bearing 329 is located on the rotation axis of the relay part 326; when the relay part 326 rotates, the water pipe 360 ​​will not rotate with the relay part 326, and remains stable on the rotation axis of the relay part 326.

[0045] After the flexible endoscope 900 is cleaned, the present invention can also dry the flexible endoscope 900 by providing a drying mechanism. Figure 2 As shown, the drying mechanism includes a drying air pump 820 and a drying nozzle 810. The drying air pump 820 is fixedly arranged inside the cabinet 100. One or more drying nozzles 810 are arranged on the tank walls of the cleaning and disinfection tank 300 on both sides of the bracket. The setting height of the drying nozzle 810 is higher than the liquid injection port 330 and the flushing nozzle 350. The drying nozzle 810 is connected to the drying air pump 820 through a drying air pipe 830. The drying nozzle 810 adopts a rotatable nozzle. After the cleaning and disinfection process of the flexible endoscope 900 is completed, the outer surface of the flexible endoscope 900 is blown dry in all directions through the drying nozzle 810. In addition, in order to dry the inside of the flexible endoscope 900, the present invention branches out a pipe from the drying air pipe 830 as a drying branch pipe 840, the drying branch pipe 840 is connected to the brushing connector 321, and an air valve is provided on the drying branch pipe 840 to control the opening and closing of the branch pipe air circuit to prevent water from entering the drying branch pipe 840 when the brush head 322 is performing brushing operation. In order to further improve the drying effect of the flexible endoscope 900, the drying mechanism in the present invention can achieve negative pressure drying by setting an exhaust hole on the groove wall of the cleaning and disinfection tank 300, and configuring a vacuum pump connected to the exhaust hole, fixing the vacuum pump inside the cabinet 100 and connecting it to the exhaust hole through an exhaust pipe. When the drying work is performed, the vacuum pump works to evacuate the cleaning and disinfection tank 300 through the exhaust hole to form a negative pressure inside the sealed cleaning and disinfection tank 300. The air pressure inside the cleaning and disinfection tank 300 is lower than the atmospheric pressure, and the boiling point of water adsorbed on the flexible endoscope 900 is reduced, thereby accelerating its evaporation rate and shortening the drying time. At the same time, the vacuum pump can also extract moisture in the cleaning and disinfection tank 300 when performing the exhaust work, thereby further improving the drying efficiency and drying effect.
