Description

Technical Field

[0001] This invention relates to the field of surgical instrument cleaning technology, specifically to an automatic cleaning, disinfection and sterilization device for veterinary surgical instruments. Background Technology

[0002] Veterinarians are professionals who use medical methods to promote harmony between the animal's body, microorganisms, and the natural environment. With more and more people keeping pets, the veterinary profession is becoming increasingly common. Correspondingly, the number of treatment or surgical instruments used in daily work is also increasing. Many instruments used in animal treatment are not disposable, and therefore require cleaning, disinfection, and sterilization after each use.

[0003] Existing technologies have disclosed some devices for cleaning and disinfecting veterinary surgical instruments, but the following problems exist in actual use: First, the functions of existing devices are incomplete, failing to integrate the cleaning, disinfection, sterilization, and wastewater treatment functions required during the cleaning process of veterinary surgical instruments, which is somewhat inconvenient; Second, after surgery, the instruments are more or less covered with animal hair. If the surgery time is too long, the instruments cannot be cleaned in time, resulting in hair sticking to the surgical instruments and being difficult to remove, which is a waste of manpower; Third, animals may carry pathogens, and the wastewater from cleaning surgical instruments is discharged directly outside the equipment without disinfection treatment, which may cause environmental pollution. Summary of the Invention

[0004] The present invention aims to solve at least one of the above-mentioned technical problems by providing an automatic cleaning, disinfection and sterilization device for veterinary surgical instruments, which integrates the cleaning, disinfection, sterilization and wastewater treatment functions required in the cleaning process of veterinary surgical instruments, thereby saving manpower and cleaning time.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic cleaning, disinfection, and sterilization device for veterinary surgical instruments includes a housing, a limiting frame, a hair-collecting roller, a hair-collecting assembly, a cleaning and disinfection assembly, and a control system. The housing has a cleaning space with an opening on one side, and a removable sealing cover is fitted to the opening of the cleaning space. The limiting frame is located within the cleaning space and connected to the housing. The hair-collecting roller is correspondingly positioned to the limiting frame and has hairs that bend in the same direction. The hair-collecting roller can reciprocate relative to the limiting frame and can rotate axially. The hair-collecting assembly is located within the cleaning space and communicates with the hair-collecting roller, and is used to clean the hairs on the hair-collecting roller. The cleaning and disinfection assembly is located on the housing and corresponds to the limiting frame, and is used to clean, disinfect, sterilize, and dry the surgical instruments. The control system controls the operation of the hair-collecting assembly and the cleaning and disinfection assembly.

[0006] Furthermore, the hair collection assembly includes a hair collection cylinder, a moving cylinder, a cyclone separator, a hair-hooking cover, and a hair-hooking motor. The hair collection cylinder is installed on one side of the cleaning space. The moving cylinder is located on one side of the hair collection cylinder and can reciprocate relative to the hair collection cylinder. The moving cylinder has a hair-collecting channel that passes through both ends and the hair-collecting channel can communicate with the hair collection cylinder. The cyclone separator is installed inside the moving cylinder. The hair-hooking cover is installed inside the moving cylinder and is located on the side of the cyclone separator opposite to the hair collection cylinder. The hair-hooking roller is covered inside the hair-hooking cover. The hair-hooking motor is connected to the hair-hooking roller.

[0007] Furthermore, the inner wall of the hook cover is provided with hooks, the hooks are curved and the bending direction of the hooks is opposite to the bending direction of the hook roller.

[0008] Further, the cleaning and disinfection assembly includes a clean water tank, a top high-pressure nozzle, a bottom cleaning and disinfection assembly, a sterilization assembly, a drying assembly, an enzyme cleaning agent box, and a peristaltic pump. The clean water tank is installed on the top of the housing. The top high-pressure nozzle is installed on the top of the inner wall of the housing and corresponds to the limiting frame. The bottom cleaning and disinfection assembly is installed in the cleaning space and located on the side of the limiting frame away from the hair-hooking roller. The top high-pressure nozzle and the bottom cleaning and disinfection assembly are both connected to the clean water tank. The sterilization assembly is installed on the top of the housing and is connected to both the top high-pressure nozzle and the bottom cleaning and disinfection assembly. The drying assembly is installed in the cleaning space and corresponds to one end of the limiting frame. The enzyme cleaning agent box is located at the rear of the housing and is connected to the clean water tank via the peristaltic pump. The peristaltic pump is also connected to the top high-pressure nozzle and the bottom cleaning and disinfection assembly. The control system is connected to the top high-pressure nozzle, the sterilization assembly, the bottom cleaning and disinfection assembly, the peristaltic pump, and the drying assembly.

[0009] Furthermore, the bottom disinfection assembly includes a bottom block, an inclined block, a bottom high-pressure nozzle, and a waste liquid box. The bottom block is located on the side of the limiting frame away from the hook roller and extends along the length of the limiting frame. The inclined blocks are disposed on the bottom block and spaced apart along the length of the bottom block. The top surface of the inclined blocks is inclined towards the limiting frame, and a drain outlet is provided through the bottom end of the inclined surface of the inclined blocks. The bottom high-pressure nozzle is installed on the top surface of the inclined blocks and faces the limiting frame. The bottom high-pressure nozzle is connected to both the disinfection and sterilization assembly and the peristaltic pump. The waste liquid box is installed at the bottom of the box and is located on the side of the bottom block away from the limiting frame.

[0010] Furthermore, the bottom cleaning and disinfection assembly also includes a bristle screen, a bristle-pushing cylinder, and a bristle-pushing plate. The bristle screen is located on the side of the waste liquid box facing the bottom block, and a bristle-pushing space is formed between the bristle screen and the bottom block. The bristle-pushing space is connected to the bristle-collecting assembly. The bristle-pushing cylinder is installed on the box body and located at the end of the bristle-pushing space away from the bristle-collecting assembly. The bristle-pushing plate is connected to the bristle-pushing cylinder and contacts the bristle screen.

[0011] Furthermore, the drying assembly includes a hot air blower and an exhaust fan. The hot air blower is installed in the cleaning space and corresponds to one end of the limiting frame, and the exhaust fan is installed on the inner wall of the housing and corresponds to the other end of the limiting frame.

[0012] Furthermore, it also includes an air purification component, which is installed outside the housing and connected to the exhaust fan.

[0013] Furthermore, the disinfection and sterilization assembly includes a heating element, a thermal disinfection section, and a pressure steam sterilization section. The heating element is installed inside the clean water tank. The thermal disinfection section and the pressure steam sterilization section are both connected to the clean water tank. The thermal disinfection section and the pressure steam sterilization section are both connected to the top high-pressure nozzle and the bottom disinfection assembly. The thermal disinfection section and the pressure steam sterilization section are both connected to the control system.

[0014] Furthermore, its working method includes the following steps: S1 Place the pre-cleaned surgical instruments on the limiting frame and close the sealing cover; S2 The heating element heats the water in the clean water tank to warm water, and the top high-pressure nozzle and the bottom cleaning component spray warm water toward the limiting frame and let it stand for a preset time; When the preset time S3 ends, the top high-pressure nozzle sprays water onto the limiting frame again. The control system analyzes the amount of water used during the formal cleaning based on the wastewater flowing through the bottom cleaning component, and obtains the amount of water used in one cleaning cycle. S4 The hair-hooking roller moves back and forth once relative to the limiting frame and rotates axially, while the hair-collecting assembly is activated to collect the hair hooked by the hair-hooking roller. S5 The peristaltic pump draws warm water from the clean water tank and mixes it with the enzyme cleaning agent from the enzyme cleaning agent box, and supplies it to the top high-pressure nozzle and the bottom cleaning component. The top high-pressure nozzle and the bottom cleaning component spray the enzyme cleaning water onto the limiting frame for 2-10 minutes. S6 The top high-pressure nozzle and the bottom cleaning component simultaneously spray hot water toward the limiting frame, and the water volume is the single water volume. During the water spraying process, the control system analyzes whether N+1 cleaning is required based on the wastewater flowing through the bottom cleaning component. If N+1 cleaning is required, the N+1 water volume is obtained, where N=0. This step is repeated until the control system analyzes and obtains that the cleanliness of the wastewater flowing through the bottom cleaning component is "qualified". The "qualified" indicator is that the cleanliness of the wastewater is consistent with the cleanliness of the water from the nozzle. The duration of this step is at least 1 minute. S7 The top high-pressure nozzle and the bottom cleaning component simultaneously spray steam toward the limiting frame. When the pressure in the cleaning space reaches 1.1 ~ 2.2 bar, maintain this pressure for 15-30 minutes. After the S8 steam pressure sterilization operation is completed, the drying component is activated to dry the pre-sterilized surgical instruments.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: In the aforementioned automatic cleaning, disinfection, and sterilization device for veterinary surgical instruments, the hair-hooking roller, moving reciprocally relative to the limiting frame and rotating axially, can remove hair adhering to the surgical instruments and centrally process it through the hair-collecting component. The hair-collecting component and waste liquid box can disinfect the waste liquid and hair before discharging them from the device, reducing environmental pollution. Therefore, integrating the cleaning, disinfection, sterilization, and wastewater treatment functions required for cleaning veterinary surgical instruments into one unit can save manpower and cleaning time.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 3As shown, a preferred embodiment of the present invention provides an automatic cleaning, disinfection, and sterilization device for veterinary surgical instruments, including a housing 1, a limiting frame 2, a hair-hooking roller 3, a hair-collecting assembly 4, a cleaning and disinfection assembly, and a control system. The housing 1 has a cleaning space 10 with an opening on one side. A detachable sealing cover 5 is installed at the opening of the cleaning space 10, and the sealing cover 5 is detachably connected to the outside of the housing 1 by bolts. The limiting frame 2 is located within the cleaning space 10 and connected to the housing 1. The hair-hooking roller 3 is correspondingly arranged with the limiting frame 2, and has hairs that bend in the same direction. The hair-hooking roller 3 can reciprocate relative to the limiting frame 2 and can rotate axially. The hair-collecting assembly 4 is located within the cleaning space 10 and communicates with the hair-hooking roller 3. The hair-collecting assembly 4 is used to clean the hairs on the hair-hooking roller 3. The cleaning and disinfection assembly is located on the housing 1 and corresponds to the limiting frame 2. The cleaning and disinfection assembly is used to clean, disinfect, sterilize, and dry the surgical instruments. The control system is used to control the operation of the hair-collecting assembly 4 and the cleaning and disinfection assembly.

[0024] In this embodiment, the lint collection assembly 4 includes a lint collection cylinder 41, a movable cylinder 42, a cyclone separator 43, a lint hook cover 44, and a lint hook motor 45. The lint collection cylinder 41 is installed on one side of the cleaning space 10, and a siphon tube with a liquid suction cover is installed at the bottom of the lint collection cylinder 41. A discharge valve is provided on the siphon tube. The movable cylinder 42 is located on one side of the lint collection cylinder 41 and can reciprocate relative to the lint collection cylinder 41. Specifically, a base plate is fixed on one side corresponding to the top of the lint collection cylinder 41, and a reciprocating motor 411 is installed on the base plate. The screw of the reciprocating motor 411 extends along the length direction of the limiting frame 2. A guide rod extends in the same direction as the screw on the side of the reciprocating motor 411 facing the inner wall of the housing 1. The barrel body of the movable cylinder 42 is provided with a through hole with internal threads and a guide hole. The through hole is threaded onto the screw of the reciprocating motor 411, and the guide hole is fitted onto the guide rod. The movable cylinder 42 is provided with a hair extraction channel 421 that runs through both ends and can connect to the hair collection cylinder 41. Specifically, the movable cylinder 42 is "﹁" shaped, and the opening on the left side of the movable cylinder 42 is provided with an electric damper 422. The hair collection cylinder 41 is provided with an opening corresponding to the electric damper 422, and a centrifugal fan 412 is provided at the opening. The cyclone separation unit 43 is installed inside the movable cylinder 42. Specifically, the cyclone separation unit 43 adopts a cyclone separation device in the prior art, which is a commonly used technical means in the field. For example, the cyclone separation device disclosed in the utility model patent with publication number CN208640603U and the cyclone separation device in the vacuum cleaner with the same device, and the cyclone separation device disclosed in the Chinese invention patent application with publication number CN1633339A, etc. The specific structure will not be described in detail. A hair-hooking cover 44 is installed inside the moving cylinder 42 and located on the side of the cyclone separator 43 opposite to the hair-collecting cylinder 41. Specifically, the hair-hooking cover 44 is installed at the opening on the right side of the moving cylinder 42. The hair-hooking roller 3 is housed inside the hair-hooking cover 44. The hair-hooking motor 45 is connected to the hair-hooking roller 3. Specifically, the hair-hooking motor 45 is installed at one end of the outer side of the moving cylinder 42, and its working shaft extends into the hair-collecting channel 421 and is driven to connect with the hair-hooking roller 3. The control system is connected to the hair-hooking motor 45, the reciprocating motor 411, the cyclone separator 43, the discharge valve, and the centrifugal fan 412, and controls the operation of the aforementioned components. The hair-hooking motor 45 drives the hair-hooking roller 3 to rotate axially, and the reciprocating motor 411 drives the moving cylinder 42 to move back and forth along the length of the limiting frame 2. As the moving cylinder 42 moves back and forth along the length of the limiting frame 2, the hair-hooking roller 3 removes hair from the surgical instruments. The cyclone separation section 43 sucks the hair held by the hair-hooking roller 3 into the hair-collecting channel 421. After the moving cylinder 42 stops moving, its left end contacts the opening of the hair-collecting cylinder 41, the electric damper 422 opens, and the centrifugal fan 412 turns on, so the hair in the moving cylinder 42 falls into the hair-collecting cylinder 41. The hair-collecting cylinder 41 contains chlorine-containing disinfectant for disinfecting the hair. After the device completes the drying operation, the discharge valve opens and the dirt in the hair-collecting cylinder 41 is removed through the siphon tube.

[0025] In this embodiment, the inner wall of the hair-hooking cover 44 is provided with hair hooks 46. The hair hooks 46 are curved, and the bending direction of the hair hooks 46 is opposite to the bending direction of the hair-hooking roller 3. The roller handle of the hair-hooking roller 3 and the hair hooks 46 are both made of stainless steel, while the hair hooks are made of nylon. When the hair-hooking roller 3 rotates axially, the hair hooks 46 can hook off the hair on the hair-hooking roller 3, thus preventing excessive hair entanglement on the hair-hooking roller 3. Because the hair hooks are made of nylon and the hair hooks 46 are made of stainless steel, the hair hooks of the hair-hooking roller 3 will not directly collide with the hair hooks 46 when the hair-hooking roller 3 rotates, but can be appropriately deformed.

[0026] In this embodiment, the disinfection assembly includes a clean water tank 60, a top high-pressure nozzle 61, a bottom disinfection assembly, a disinfection and sterilization assembly 62, a drying assembly 63, an enzyme cleaning agent box 65, and a peristaltic pump. The clean water tank 60 is installed at the top rear of the housing 1 and is connected to a water source via a pipe. The top high-pressure nozzle 61 is installed on the top of the inner wall of the housing 1 and corresponds to the limiting frame 2. The bottom disinfection assembly is installed in the cleaning space 10 and is located on the side of the limiting frame 2 away from the hook roller 3. The top high-pressure nozzle 61 and the bottom disinfection assembly are all connected to the clean water tank 60 via pipes, and a first four-way valve is provided on the pipes.

[0027] The disinfection and sterilization component 62 is installed on the top of the housing 1. The disinfection and sterilization component 62 is connected to the top high-pressure nozzle 61 and the bottom cleaning and sterilization component. Specifically: The disinfection and sterilization assembly 62 includes a heating element, a thermal disinfection section 621, and a pressure steam sterilization section 622. The heating element is installed inside the clean water tank 60. Both the thermal disinfection section 621 and the pressure steam sterilization section 622 are connected to the clean water tank 60; both are also connected to the top high-pressure spray head 61 and the bottom disinfection assembly. Specifically, the thermal disinfection section 621 includes a high-pressure circulation pump, a water supply solenoid valve, a hot water spray solenoid valve, and a hot water connection pipe. The hot water connection pipe is connected to a first four-way valve at the outlet of the clean water tank 60, and is also connected to the high-pressure circulation pump. The hot water connection pipe is also connected to the top high-pressure spray head 61 and the bottom disinfection assembly via a second four-way valve. The water supply solenoid valve and the hot water spray solenoid valve are installed on the hot water connection pipe. The installation of the high-pressure circulation pump, water supply solenoid valve, and hot water spray solenoid valve on the hot water connection pipe is a common practice in the art. The specific structure, use, and installation methods of the technical means will not be elaborated here. The pressure steam sterilization unit 622 includes a steam generator, a steam connection pipeline, a pressure sensor, a steam inlet solenoid valve, and a steam spray solenoid valve. The steam generator is connected to the first four-way valve at the outlet of the clean water tank 60, and the steam connection pipeline is connected to the steam generator. The steam connection pipeline is also connected to the top high-pressure nozzle 61 and the bottom cleaning and disinfection assembly through the aforementioned second four-way valve. The steam inlet solenoid valve and the steam spray solenoid valve are both installed on the steam connection pipeline. Their connection methods, specific structures, and usage methods are all common technical means in this field and will not be elaborated here. The pressure sensor is installed in the cleaning space 10 and is used to monitor the pressure in the cleaning space 10 in real time. Both the thermal disinfection unit 621 and the pressure steam sterilization unit 622 are connected to the control system. Specifically, the heating element, high-pressure circulating pump, water supply solenoid valve, hot water spray solenoid valve, steam generator, pressure sensor, steam inlet solenoid valve, steam spray solenoid valve, and pressure sensor are all connected to the control system, which controls the operation of the aforementioned components.

[0028] The bottom cleaning assembly includes a bottom block 641, an inclined block 642, a bottom high-pressure nozzle 643, and a waste liquid box 644. The bottom block 641 is located on the side of the limiting frame 2 opposite to the hook roller 3 and extends along the length of the limiting frame 2. The periphery of the bottom block 641 is connected to the inner wall of the housing 1. The inclined blocks 642 are disposed on the bottom block 641 and spaced apart along the length of the bottom block 641. The top surface of the inclined blocks 642 is inclined towards the limiting frame 2, and a drain outlet 640 is provided through the bottom end of the inclined surface of the inclined blocks 642. A conductivity sensor is installed on the top surface of the inclined blocks 642. The conductivity sensor is used to monitor the conductivity of the liquid flowing through the top surface of the inclined blocks 642 in real time, indirectly calculating the concentration of the liquid, such as cleaning agents, or determining whether the total ion content has dropped to a qualified level, such as rinsing water. The bottom high-pressure nozzle 643 is mounted on the top surface of the inclined block 642 and faces the limiting frame 2. The bottom high-pressure nozzle 643 is connected to the disinfection and sterilization component 62, the hot water connection pipe, the steam connection pipe, and the second four-way valve connecting the clean water tank 60. The waste liquid box 644 is installed at the bottom of the box body 1 and is located on the side of the bottom block 641 away from the limiting frame 2. The waste liquid box 644 is used to hold chlorine-containing disinfectant. A drain pipe 649 is installed at the bottom of the waste liquid box 644, and a drain valve is installed on the drain pipe 649. The inclined top surface of the inclined block 642 not only allows the bottom high-pressure nozzle 643 to be closer to the surgical instruments placed on the limiting frame 2, but also ensures that the liquid used for disinfection flows through the conductivity sensor. This not only enables real-time monitoring of the disinfection liquid, but also effectively reduces the possibility of the conductivity sensor being damaged by prolonged immersion in waste liquid.

[0029] The bottom cleaning assembly also includes a bristle screen 645, a bristle-pushing cylinder 646, and a bristle-pushing plate 647. The bristle screen 645 is located on the side of the waste liquid box 644 facing the bottom block 641, forming a bristle-pushing space 648 between the bristle screen 645 and the bottom block 641. The bristle-pushing space 648 is connected to the bristle-collecting assembly 4. Specifically, the bristle-collecting cylinder 41 has a through hole corresponding to the position of the bristle-pushing space 648, and the through hole is connected to the bristle-pushing space 648. The bristle-pushing cylinder 646 is mounted on the housing 1 and located at the end of the bristle-pushing space 648 away from the bristle-collecting assembly 4. The bristle-pushing plate 647 is connected to the bristle-pushing cylinder 646 and contacts the bristle screen 645. When remaining hair on the surgical instruments is washed onto the inclined block 642, the hair flows with the water from the drain 640 onto the hair-collecting screen 645, where it is retained. The wastewater is filtered into the waste liquid box 644. When the hair-pushing cylinder 646 pushes the hair-pushing plate 647 towards the hair-collecting cylinder 41, the hair on the hair-collecting screen 645 is pushed into the hair-collecting cylinder 41 for centralized treatment. The waste liquid box 644 contains chlorine-containing disinfectant for further sterilization and disinfection of the waste liquid, which is then discharged through the drain pipe 649.

[0030] The drying assembly 63 is installed within the cleaning space 10 and corresponds to one end of the limiting frame 2. Specifically, the drying assembly 63 includes a hot air blower 631 and an exhaust fan 632. The hot air blower 631 is installed within the cleaning space 10 and corresponds to one end of the limiting frame 2. Specifically, a mounting platform is provided below the base plate corresponding to the lint collector 41, and the hot air blower 631 is mounted on the mounting platform. It should be noted that a heating electric damper is provided on the wall of the housing 1 corresponding to the position of the hot air blower 631. The area between the hot air blower 631, the base block 641, and the lint roller 3 corresponds to the area where hot air blows towards the limiting frame 2 and the inclined block 642. The exhaust fan 632 is installed on the inner wall of the housing 1 and corresponds to the other end of the limiting frame 2. The hot air blown by the hot air blower 631 can dry the surgical instruments on the limiting frame 2 and can also dry the inclined block 642 simultaneously.

[0031] The enzyme cleaning agent box 65 is located at the rear of the housing 1 and is connected to the clean water tank 60 via a peristaltic pump. The enzyme cleaning agent box 65 is used to hold the enzyme cleaning agent, and the peristaltic pump is used to mix the clean water and enzyme cleaning agent to obtain an enzyme cleaning spray solution of appropriate concentration. The peristaltic pump is also connected to the top high-pressure nozzle 61 and the bottom cleaning assembly. Specifically, the top high-pressure nozzle 61 and the bottom high-pressure nozzle 643 are connected to the outlet end of the second four-way valve. The other three ports of the second four-way valve are respectively connected to the peristaltic pump, the steam generator, and the high-pressure circulating pump through pipelines. The control system is connected to the top high-pressure nozzle 61, the bottom high-pressure nozzle 643, the hair-pushing cylinder 646, the peristaltic pump, the hot air blower 631, the drain valve, and the exhaust fan 632. The control system is used to control the operation of the aforementioned components.

[0032] In this embodiment, the automatic cleaning, disinfection, and sterilization device for veterinary surgical instruments also includes an air purification component 7. The air purification component 7 is installed outside the housing 1 and connected to the exhaust fan 632. The air purification component 7 uses a HEPA high-efficiency filter, the principle of which is existing technology and will not be described further here. The air purification component 7 purifies the air drawn out by the exhaust fan 632, further reducing the possibility of environmental pollution. The control system is connected to the air purification component 7 and controls its operation.

[0033] In this embodiment, the control system includes a PLC controller and a control panel. The PLC controller is connected to the heating element, the hair-hooking motor 45, the reciprocating motor 411, the cyclone separator 43, the centrifugal fan 412, the discharge valve, the high-pressure circulating pump, the water supply solenoid valve, the hot water spray solenoid valve, the steam generator, the pressure sensor, the steam inlet solenoid valve, the steam spray solenoid valve, the pressure sensor, the conductivity sensor, the top high-pressure nozzle 61, the bottom high-pressure nozzle 643, the hair-pushing cylinder 646, the peristaltic pump, the hot air blower 631, the exhaust fan 632, the drain valve, the air purification component 7, and a network communication module. The PLC controller can receive control commands from the control panel to control the heating element, the hair-hooking motor 45, the reciprocating motor 411, the cyclone separator 43, the centrifugal fan 412, the discharge valve, the high-pressure circulating pump, the water supply solenoid valve, the hot water spray solenoid valve, the steam generator, the pressure sensor, the steam inlet solenoid valve, the steam spray solenoid valve, the top high-pressure nozzle 61, the bottom high-pressure nozzle 643, the hair-pushing cylinder 646, the peristaltic pump, the hot air blower 631, the exhaust fan 632, the drain valve, and the air purification component 7. A network communication module is used to receive commands from a remote terminal and transmit them to the control system. The connection and configuration of the PLC controller with the control panel and other devices are well-known to those skilled in the art. For example, similar technical means are described in existing technical documents such as Chinese Utility Model Patent CN206049025U (a nozzle air path control system) and Chinese Utility Model Patent CN215223649U (a landscape automatic sprinkler control system). Therefore, the control system configuration in this embodiment is existing technology and does not involve any improvement to the program.

[0034] The working method of the above-mentioned automatic cleaning, disinfection and sterilization device for veterinary surgical instruments includes the following steps: S1 Place the pre-cleaned surgical instruments on the limiting frame 2, close the sealing cover 5 and tighten the bolts; S2 heating element heats the water in the clean water tank 60 to 40°C. The peristaltic pump draws only warm water to supply the top high-pressure nozzle 61 and the bottom high-pressure nozzle 643. The top high-pressure nozzle 61 and the bottom high-pressure nozzle 643 spray warm water toward the limit frame 2 and let it stand for 30 minutes. S3 When 30 minutes have passed, the top high-pressure nozzle 61 sprays water towards the limit frame 2 again. The control system analyzes the amount of water used during the formal cleaning based on the wastewater flowing through the conductivity sensor and obtains the amount of water used in one cleaning cycle. S4 The hair-hooking motor 45 drives the hair-hooking roller 3 to rotate axially, and the reciprocating motor 411 drives the moving cylinder 42 to move back and forth relative to the limit frame 2 once. At the same time, the cyclone separation section 43 is started and the electric damper 422 is closed. When the moving cylinder 42 finishes one reciprocating movement, the electric damper 422 and the centrifugal fan 412 are both opened and the cyclone separation section 43 is closed. The hair in the moving cylinder 42 is drawn to the hair collection cylinder 41 to come into contact with the chlorine-containing disinfectant for disinfection. S5 peristaltic pump draws warm water from clean water tank 60 and enzyme cleaning agent from enzyme cleaning agent box 65, mixes them, and supplies them to top high pressure nozzle 61 and bottom high pressure nozzle 643. Top high pressure nozzle 61 and bottom high pressure nozzle 643 spray enzyme cleaning water toward limit frame 2 for 2-10 minutes. The S6 heating element continuously heats the water to 90°C. The high-pressure circulating pump and the corresponding pipeline valves supply hot water to the top high-pressure nozzle 61 and the bottom high-pressure nozzle 643. The top high-pressure nozzle 61 and the bottom high-pressure nozzle 643 simultaneously spray hot water towards the limit frame 2. The water volume sprayed is the water volume used in one cycle. During the water spraying process, the control system analyzes the sewage flowing through the conductivity sensor to determine whether N+1 cleaning cycles are needed. If N+1 cleaning cycles are needed, the water volume of N+1 is obtained, where N=0. This step is repeated until the control system analyzes and obtains that the cleanliness of the sewage flowing through the conductivity sensor is "qualified". The indicator of "qualified" is that the cleanliness of the sewage is consistent with the cleanliness of the water exiting the nozzle. The duration of this step is at least 2 minutes. S7 The high-pressure circulating pump and the corresponding pipeline valves are closed, the heating element continues to heat and produce steam, and the steam generator and the corresponding pipeline valves operate to supply steam to the top high-pressure nozzle 61 and the bottom high-pressure nozzle 643. The top high-pressure nozzle 61 and the bottom high-pressure nozzle 643 simultaneously spray steam towards the limit frame 2. When the pressure in the cleaning space 10 reaches 1.1 ~ 2.2 bar, the pressure is maintained for 15-30 minutes. During this process, the pressure sensor constantly monitors the pressure in the cleaning space 10. When the pressure is too high, the exhaust fan 632 is turned on to exhaust the air appropriately. After the S8 steam pressure sterilization operation is completed, the hot air blower 631, exhaust fan 632 and air purification component 7 are activated to dry the pre-cleaned surgical instruments, thus completing the cleaning, sterilization and disinfection of the surgical instruments. S9 push cylinder 646 starts, push plate 647 pushes the hair concentrated on the hair net 645 into hair collection cylinder 41, and let it stand for 60 minutes; drain valve discharges wastewater in waste liquid box 644, and discharge valve discharges waste in hair collection cylinder 41.

[0035] The above-mentioned automatic cleaning, disinfection, and sterilization device for veterinary surgical instruments has the following effects: First, when the top high-pressure nozzle 61 and the bottom high-pressure nozzle 643 are in operation, they spray the surgical instruments simultaneously. The water flow generated by the high pressure can not only wash away the dirt on the surgical instruments, but also confine the surgical instruments to the limiting frame 2.

[0036] Secondly, the system is equipped with a conductivity sensor and the control system allocates cleaning water based on the real-time sensing results of the conductivity sensor, which can ensure thorough cleaning while saving water.

[0037] Third, the cleaning, disinfection, sterilization of veterinary surgical instruments, as well as the treatment of waste liquid and hair, are all completed within this device, which can save manpower and cleaning time.

[0038] As can be seen, the automatic cleaning, disinfection and sterilization device for veterinary surgical instruments of this embodiment integrates the cleaning, disinfection, sterilization and wastewater treatment functions required in the cleaning process of veterinary surgical instruments, which can save manpower and cleaning time, and is convenient and fast.
