[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a sterilization and disinfection device, such as Figure 1-15As shown, the sterilization and disinfection equipment includes: a sterilization box 1 and a solution tank 2, an isolation plate 3 is fixedly installed in the sterilization box 1 to isolate the transmission space and the disinfection space in the sterilization box 1, and the transmission space is located above the disinfection space; a support column 4 is rotatably installed on the isolation plate 3, the top end of the support column 4 is located in the transmission space, and the bottom end is located in the disinfection space, the support column 4 is provided with a solution channel from the top downward, and the bottom end of the support column 4 is a closed end; a plurality of inner cylinders 5 are rotatably sleeved on the part of the support column 4 located in the disinfection space, and the outer ends of the plurality of inner cylinders 5 are each provided with an outer cylinder 6 fixedly connected to the inner wall of the sterilization box 1, and the corresponding bottoms of the inner cylinder 5 and the outer cylinder 6 are fixed with a connecting plate 7 to keep the inner cylinder 5 and the outer cylinder 6 stationary with the sterilization box 1; a storage circular plate 8 is slidably provided between the plurality of inner cylinders 5 and the outer cylinder 6 for placing items to be sterilized, and the storage circular plate 8 slides back and forth up and down between the corresponding inner cylinder 5 and outer cylinder 6 so that the items placed inside are bumped and contacted with the disinfectant flowing on the surface of the storage circular plate 8. Multiple inner cylinders 5, outer cylinders 6 and storage circular plates 8 are arranged in groups, and multiple storage circular plates 8 are provided with drainage holes 10 for discharging waste liquid; multiple spray pipes 9 are fixedly installed on the part of the support column 4 located in the disinfection space, and multiple spray pipes 9 are connected to the solution channel. The spray pipes 9 rotate with the support column 4. Multiple spray pipes 9 are staggered with the inner cylinder 5, outer cylinder 6 and storage circular plates 8 arranged in groups. The spray pipes 9 are located above the corresponding storage circular plates 8 and are used to spray disinfectant onto the storage circular plates 8 to disinfect the items above; a liquid pumping mechanism, the liquid pumping mechanism is arranged on the sterilization box 1 and the solution tank 2, and is used to pump the solution in the solution tank 2 to the solution channel of the support column 4, and finally spray it onto the storage circular plate 8 by the spray pipe 9.

[0035] In this embodiment, when the sterilization and disinfection equipment is used, the items to be sterilized and disinfected are first placed on a plurality of storage circular plates 8. These storage circular plates 8 are located between the inner cylinder 5 and the outer cylinder 6 arranged in groups. The inner cylinder 5 and the outer cylinder 6 are fixedly connected to the inner wall of the sterilization box 1 through the connecting plate 7 and remain stationary. Then, the pump mechanism is started to pump the disinfectant in the solution tank 2 into the solution channel of the support column 4. The disinfectant is sprayed onto the storage circular plates 8 through the spray pipe 9 of the support column 4. During the spraying process, the support column 4 drives the spray pipe 9 to rotate, so that the disinfectant is evenly sprayed on the surface of the items on the storage circular plates 8. At the same time, the storage circular plates 8 slide back and forth between the inner cylinder 5 and the outer cylinder 6. The bumpy effect caused by this sliding makes the items fully contact with the disinfectant flowing on the surface of the storage circular plates 8, thereby achieving comprehensive disinfection of the items. After a period of disinfection, the waste liquid is discharged through the drainage hole 10 on the storage circular plates 8, completing the entire sterilization and disinfection process.

[0036] This sterilization and disinfection equipment has significant beneficial effects. It has a storage circular plate 8 that is slidably arranged between multiple inner cylinders 5 and outer cylinders 6. The items placed on the storage circular plate 8 can be bumped as the storage circular plate 8 slides up and down during the disinfection process, and the items are in full contact with the disinfectant on the surface of the storage circular plate 8. Compared with traditional immersion or spray disinfection methods, this design effectively avoids the problem that the bottom of the items is difficult to contact the disinfectant, ensuring the comprehensiveness of the disinfection. At the same time, the inner cylinder 5, outer cylinder 6 and storage circular plate 8 arranged in groups, as well as the drainage holes 10 on the storage circular plate 8, enable the waste liquid to be discharged smoothly, further improving the disinfection effect and the operating efficiency of the equipment. In addition, the design of the spray pipe 9 rotating with the support column 4 ensures the uniform spraying of the disinfectant, further improving the uniformity and thoroughness of the disinfection.

[0037] This sterilization and disinfection device achieves efficient and comprehensive disinfection of medical devices and other items. Its core component, the storage disc 8, slides back and forth between the inner and outer cylinders 5 and 6, and cooperates with the rotating spraying of the spray pipe 9 to ensure full contact between the items and the disinfectant, effectively solving the problems of traditional disinfection methods.

[0038] In a further preferred embodiment of the present invention, the placement circular plate 8 is at the same height as the corresponding inner cylinder 5 and outer cylinder 6, and the thickness of the placement circular plate 8 is at most 1 / 4 of the height of the inner cylinder 5, so that there is a groove for placing items between the inner cylinder 5, the outer cylinder 6 and the placement circular plate 8.

[0039] In this embodiment, the size of the storage circular plate 8 is optimized. Specifically, the height of the storage circular plate 8 is consistent with that of the inner cylinder 5 and the outer cylinder 6, and its thickness is strictly controlled to be at most 1 / 4 of the height of the inner cylinder 5. Such a size design allows a groove with a certain depth to be formed between the inner cylinder 5, the outer cylinder 6 and the storage circular plate 8, which is used to place items to be sterilized. During actual operation, the items are placed in this groove. When the storage circular plate 8 slides back and forth up and down between the inner cylinder 5 and the outer cylinder 6, the items can be bumped in the groove with the movement of the storage circular plate 8, thereby fully contacting with the disinfectant flowing on the surface of the storage circular plate 8, thereby achieving effective sterilization and disinfection. This size-optimized design further improves the equipment's capacity to accommodate items and the disinfection effect.

[0040] In a further preferred embodiment of the present invention, the liquid pumping mechanism includes a protective shell 11, a pump body 12, an inlet pipe 13 and a discharge pipe 14. The protective shell 11 is fixedly mounted on the solution tank 2, and the pump body 12 is fixedly mounted in the protective shell 11. The inlet pipe 13 and the discharge pipe 14 are respectively mounted on the inlet and discharge ends of the pump body 12. The inlet end of the inlet pipe 13 extends into the solution tank 2, and the discharge end of the discharge pipe 14 extends into the solution channel of the support column 4 after passing through the transmission space. The discharge end of the discharge pipe 14 is mounted in the solution channel using a watertight bearing so that the support column 4 can rotate along the discharge end of the discharge pipe 14.

[0041] In this embodiment, the arrangement of the pump mechanism provides a stable power for delivering disinfectant for the sterilization and disinfection equipment. The pump mechanism includes a protective shell 11, a pump body 12, a liquid inlet pipe 13 and a liquid discharge pipe 14. The protective shell 11 is fixedly mounted on the solution tank 2 to protect the pump body 12 and prevent external factors from damaging the pump body 12. The pump body 12 is fixedly mounted in the protective shell 11 and is the core component of the pump mechanism, responsible for extracting and delivering the disinfectant in the solution tank 2. The liquid inlet pipe 13 is mounted on the liquid inlet end of the pump body 12, and its liquid inlet end extends into the solution tank 2 to ensure that the disinfectant can be smoothly introduced into the pump body 12. The liquid discharge pipe 14 is mounted on the liquid discharge end of the pump body 12, and its liquid discharge end extends into the solution channel of the support column 4 after passing through the transmission space, and is used to deliver the pumped disinfectant to the spray pipe 9, and then spray it onto the surface of the items on the storage circular plate 8. In particular, the discharge end of the discharge pipe 14 is installed in the solution channel using a watertight bearing. This installation method allows the support column 4 to rotate at the discharge end of the discharge pipe 14, which not only ensures the stable delivery of the disinfectant, but also does not affect the function of the support column 4 to drive the spray pipe 9 to rotate, thereby realizing the organic combination of pumping liquid and rotary spraying.

[0042] In a further preferred embodiment of the present invention, the pump body 12 is a plunger pump, and a plurality of nozzles 15 are fixedly mounted on the bottom of each of the plurality of spray pipes 9 for spraying the disinfectant into atomized form toward the placement circular plate 8 .

[0043] In this embodiment, the pump body 12 adopts a plunger pump. This pump body structure can provide stable high-pressure liquid delivery, ensuring that the disinfectant can be delivered to the spray pipe 9 with sufficient pressure. At the same time, multiple nozzles 15 are fixedly installed at the bottom of the multiple spray pipes 9. The function of these nozzles 15 is to atomize the disinfectant and spray it onto the storage circular plate 8. During specific operation, the plunger pump 12 draws the disinfectant in the solution tank 2 through the liquid inlet pipe 13, and delivers it to the solution channel of the support column 4 in a high-pressure manner through the discharge pipe 14. The disinfectant then flows into the spray pipe 9 and is atomized into fine droplets through the nozzle 15, and is evenly sprayed on the surface of the objects on the storage circular plate 8. This atomized spraying method can make the disinfectant cover the surface of the objects more evenly, thereby improving the disinfection effect.

[0044] In a further preferred embodiment of the present invention, the bottom of the sterilization box 1 has a drain port, and a liquid collecting box 16 corresponding to the drain port is fixedly installed at the bottom of the sterilization box 1 for collecting waste liquid. A sewage pipe 17 with a valve is installed at the bottom of the liquid collecting box 16 for discharging waste liquid.

[0045] In this embodiment, a drain port is provided at the bottom of the sterilization box 1, and a corresponding liquid collecting box 16 is fixedly installed thereto for collecting waste liquid discharged from the sterilization box 1. A drain pipe 17 with a valve is installed at the bottom of the liquid collecting box 16. By controlling the opening and closing of the valve, the waste liquid in the liquid collecting box 16 can be discharged. In actual operation, when the sterilization process is completed, the waste liquid on the storage circular plate 8 is discharged through the drain hole 10, flows into the liquid collecting box 16 through the drain port at the bottom of the sterilization box 1 for collection, and then the valve on the drain pipe 17 is opened to discharge the waste liquid out of the equipment, completing the waste liquid treatment process. This design realizes the orderly collection and discharge of waste liquid, facilitates the centralized treatment of waste liquid, and avoids the pollution to the environment caused by the direct discharge of waste liquid.

[0046] In a further preferred embodiment of the present invention, a conical toothed disc 18 is fixedly mounted on the top of the support column 4 located in the transmission space, a motor 19 located in the transmission space is fixedly mounted on the top of the isolation plate 3, and an active bevel gear 20 is fixedly mounted on the output shaft of the motor 19. The active bevel gear 20 is engaged with the conical toothed disc 18 so that the motor 19 drives the support column 4 to rotate.

[0047] In this embodiment, a bevel gear disc 18 is fixedly mounted on the top of the support column 4 within the transmission space. Simultaneously, a motor 19 is fixedly mounted on the top of the isolation plate 3 within the transmission space, and a driving bevel gear 20 is fixedly mounted on the output shaft of the motor 19. By meshing the driving bevel gear 20 with the bevel gear disc 18, when the motor 19 is started, its output shaft drives the driving bevel gear 20 to rotate, which in turn, through gear meshing transmission, drives the bevel gear disc 18 and the support column 4 fixedly connected thereto to rotate. This drive method utilizes the power output of the motor 19, which, through the bevel gear transmission, achieves stable rotation of the support column 4, thereby driving the spray pipe 9 to rotate, allowing the disinfectant to be evenly sprayed onto the surface of the items on the storage circular plate 8, providing effective power support for the sterilization process.

[0048] In a further preferred embodiment of the present invention, one side of the sterilization box 1 has an operation port and is equipped with a cabinet door 21, four support legs 22 are fixedly installed on the bottom of the sterilization box 1, and the top of the solution tank 2 has a liquid filling port and is equipped with a cover 23.

[0049] In this embodiment, the operating port on one side of the sterilization box 1 and the cabinet door 21 provide a convenient operating channel for the staff, making the placement and removal of items to be sterilized easier and faster, thereby improving work efficiency. At the same time, the provision of four supporting legs 22 ensures the stability of the sterilization box 1 during operation, avoiding problems such as poor disinfection effect or equipment damage caused by equipment shaking. Secondly, the design of the liquid filling port and the cover 23 on the top of the solution tank 2 makes it convenient for the staff to add disinfectant to the solution tank 2 at any time, ensuring the supply of disinfectant. The sealing design of the cover 23 can also effectively prevent the volatilization and contamination of the disinfectant during storage, ensuring the quality and safety of the disinfectant.

[0050] In a further preferred embodiment of the present invention, the two supporting legs 22 on the corresponding sides are fixedly connected by a cross bar 24, and an evaporation box 25 is fixedly installed between the two cross bars 24. The evaporation box 25 is located below the liquid collecting box 16. An electric heating component 26 is installed in the evaporation box 25 for heating the solution to generate steam. A steam exhaust pipe 27 is installed on the top of the evaporation box 25. The exhaust end of the steam exhaust pipe 27 extends to one side of the sterilization box 1 and is fixedly installed with a cross pipe 28. A plurality of cross pipes 28 are arranged at the bottom of the sterilization space of the sterilization box 1. The steam distribution pipe 29, a plurality of the steam distribution pipes 29 extend to the outside of the sterilization box 1 and are fixedly connected to the horizontal pipe 28. The plurality of the steam distribution pipes 29 are located below the bottom end of the support column 4 and below the plurality of inner tubes 5, outer tubes 6 and the storage circular plate 8. The bottom of the plurality of the steam distribution pipes 29 is fixedly installed with a branch pipe 30, which is arranged vertically downward to introduce steam into the sterilization box 1 and prevent the solution from entering. The sterilization box 1 is a rectangular box, and its four corners have steam flow channels staggered by the outer tube 6, and the steam flows along the steam flow channels.

[0051] In this embodiment, a steam disinfection system is constructed to enhance the functionality of the sterilization and disinfection equipment. The specific implementation method is as follows: The two supporting legs 22 on corresponding sides are fixedly connected by a crossbar 24, enhancing the structural stability of the entire device. An evaporation box 25 is fixedly mounted between the two crossbars 24 and located below the liquid collection tank 16. An electric heating assembly 26 is installed inside the evaporation box 25, whose primary function is to heat the solution and generate steam for disinfection. A steam exhaust pipe 27 is installed at the top of the evaporation box 25. The exhaust end of this steam exhaust pipe 27 extends to the side of the sterilization box 1 and is connected to a fixed crossbar 28. Multiple steam distribution pipes 29 are arranged and installed at the bottom of the sterilization space of the sterilization box 1. These steam distribution pipes 29 extend outside the sterilization box 1 and are fixedly connected to the crossbar 28. It is worth noting that the multiple steam distribution pipes 29 are located below the bottom end of the support column 4 and below the multiple inner and outer cylinders 5 and 6 and the storage circular plate 8. Furthermore, a vertically downward branch pipe 30 is fixedly mounted at the bottom of each steam distribution pipe 29. Its primary function is to direct steam into the sterilizer 1 while preventing the ingress of liquid. The sterilizer 1 is designed as a rectangular box, with steam flow channels at each corner, offset by an outer tube 6. This allows steam to flow smoothly along these channels, thereby achieving omnidirectional steam sterilization of items within the sterilizer 1.

[0052] In a further preferred embodiment of the present invention, a pressure relief pipe 31 with a solenoid valve is fixedly installed on one side of the sterilization box 1, and the pressure relief pipe 31 is connected to the top of the disinfection space. A pressure sensor and a temperature sensor are provided in the disinfection space, and the pressure sensor and the temperature sensor are both connected to the solenoid valve for controlling the opening and closing of the pressure relief pipe 31.

[0053] In this embodiment, a pressure relief pipe 31 with a solenoid valve is fixedly installed on one side of the sterilization box 1, and the pressure relief pipe 31 is connected to the top of the disinfection space. At the same time, a pressure sensor and a temperature sensor are provided in the disinfection space, and both sensors are connected to the solenoid valve. In actual operation, when the pressure or temperature in the sterilization box 1 reaches a preset safety threshold, the pressure sensor or temperature sensor will transmit a signal to the solenoid valve. After receiving the signal, the solenoid valve automatically opens the pressure relief pipe 31, so that the excess steam in the disinfection space is discharged through the pressure relief pipe 31, thereby reducing the pressure and temperature and ensuring the safety of the equipment operation. When the pressure and temperature drop to a safe range, the sensor sends a signal again, and the solenoid valve closes the pressure relief pipe 31 to maintain a normal working environment in the disinfection space. The design of this intelligent pressure relief system realizes real-time monitoring and automatic control of the pressure and temperature in the sterilization box 1, effectively ensuring the safe operation of the equipment.

[0054] In a further preferred embodiment of the present invention, the top of the evaporator 25 has a filling port and is equipped with a second cover 32, and a controller is installed on the cabinet door 21, and the controller is connected to the pump body 12, the motor 19, the electric heating component 26 and the solenoid valve.

[0055] In this embodiment, a filling port is provided on the top of the evaporation box 25, and a sealing cover 32 is provided to facilitate the addition of solution into the evaporation box 25 while ensuring the sealing during use. In addition, a controller is installed on the cabinet door 21, which is connected to the pump body 12, the motor 19, the electric heating component 26 and the solenoid valve. Through the controller, the operator can centrally control the operation of these key components to achieve automated management of the entire sterilization and disinfection process. For example, the operator can use the controller to start the pump body 12 to deliver disinfectant, control the motor 19 to drive the support column 4 to rotate, adjust the heating power of the electric heating component 26, and control the opening and closing of the solenoid valve to achieve pressure relief. This integrated control design makes the operation of the equipment more convenient and efficient, reduces manual intervention, and improves the operational stability and reliability of the equipment.

[0056] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0057] In another embodiment of the present invention, the sterilization and disinfection equipment also includes a vibration drive mechanism, which includes a driven shaft 38, and the driven shaft 38 is rotatably installed on the other side of the sterilization box 1 corresponding to the cabinet door 21. One end of the driven shaft 38 is located in the transmission space and is fixedly installed with a driven bevel gear 39. The driven bevel gear 39 is meshed with the bevel gear disk 18 so that the support column 4 drives the driven shaft 38 to rotate. The bottoms of the multiple inner cylinders 5 and the outer cylinders 6 are fixedly installed with metal shrapnel 34, and the bottoms of the multiple metal shrapnel 34 are fixedly installed with L-shaped brackets 33. The L-shaped bracket 33 is fixedly connected to the bottom of the corresponding storage circular plate 8 so that the storage circular plate 8 is suspended and supported. The sterilization box 1 is rotatably installed with multiple camshafts 35 and tensioning wheels 41 on one side of the driven shaft 38, and the multiple camshafts 35 extend to the sterilization The space is located below the multiple storage circular plates 8 respectively. The multiple cam shafts 35 are fixedly provided with a pushing cam 36, and the bottoms of the multiple storage circular plates 8 are fixedly installed with a force-bearing piece 37. The force-bearing piece 37 contacts the corresponding pushing cam 36, so that when the cam shaft 35 drives the pushing cam 36 to rotate, the pushing force-bearing piece 37 and the storage circular plate 8 move upward, and the storage circular plate 8 moves upward to drive the L-shaped bracket 33 to move upward and compress the metal spring piece 34. The driven shaft 38 and the multiple cam shafts 35 are fixedly installed with a synchronous wheel 40 at one end outside the sterilization box 1. The multiple synchronous wheels 40 and the tensioning wheel 41 are covered with the same synchronous belt 42, so that the driven shaft 38 drives the multiple cam shafts 35 to rotate. A plurality of stabilizing frames 43 are fixedly installed on the inner wall of the disinfection space, and the multiple stabilizing frames 43 are respectively rotatably connected to the multiple cam shafts 35.

[0058] In this embodiment, a vibration drive mechanism is added to enhance the sterilization and disinfection effect. This mechanism includes a driven shaft 38, which is rotatably mounted on the other side of the sterilization chamber 1 corresponding to the cabinet door 21. One end of the mechanism is located within the transmission space and is fixedly mounted with a driven bevel gear 39. The driven bevel gear 39 engages with the bevel gear disc 18, and the support column 4 drives the driven shaft 38 to rotate. In addition, a metal spring 34 is fixedly mounted at the bottom of each inner cylinder 5 and outer cylinder 6. The bottom of the metal spring 34 is connected to an L-shaped bracket 33, which is then fixed to the bottom of the storage circular plate 8, thereby achieving suspended support for the storage circular plate 8. The sterilization chamber 1 has multiple camshafts 35 and a tensioning pulley 41 rotatably mounted on one side of the driven shaft 38. The camshaft 35 extends into the disinfection space and is located below each storage circular plate 8. A push cam 36 is fixedly mounted on the bottom of the storage circular plate 8. A force-bearing plate 37 is fixedly mounted on the bottom of the storage circular plate 8, contacting the push cam 36. When the camshaft 35 rotates, the push cam 36 pushes the force-bearing plate 37, causing the storage circular plate 8 to move upward, thereby driving the L-shaped bracket 33 to move upward and compressing the metal spring 34. The driven shaft 38 and the end of each camshaft 35 located outside the sterilization box 1 are both equipped with a synchronous pulley 40, and the same synchronous belt 42 is sleeved with the tensioning pulley 41, so that the driven shaft 38 drives multiple camshafts 35 to rotate. A stabilizing frame 43 is fixedly installed on the inner wall of the disinfection space and is rotatably connected to each camshaft 35 to ensure its stable rotation. During the sterilization process, the support column 4 rotates to drive the driven shaft 38, which is transmitted through the synchronous belt 42 to drive the camshaft 35 to rotate. The push cam 36 periodically pushes the force-bearing plate 37, causing the storage circular plate 8 to vibrate up and down, thereby enhancing the contact between the disinfectant and the items and improving the disinfection effect.

[0059] The added vibration drive mechanism in this embodiment significantly enhances the effectiveness of the sterilization and disinfection device. First, the linkage design between the driven shaft 38 and the support column 4 utilizes the rotational power of the support column 4, eliminating the need for an additional power source and ensuring stable rotation of the driven shaft 38. Second, the combination of the metal spring 34 and the L-shaped bracket 33 provides reliable suspension support for the storage disc 8, ensuring stability during vibration. The camshaft 35 and the push cam 36 periodically push the force-bearing plate 37, causing the storage disc 8 to vibrate up and down. This vibration effectively enhances contact between the disinfectant and the items, ensuring a more even distribution of the disinfectant across the surface of the items. This is especially true for items with complex shapes or irregular surfaces, as vibration allows the disinfectant to better penetrate into gaps and corners, significantly improving the uniformity and thoroughness of disinfection. The transmission design of the synchronous pulley 40, synchronous belt 42, and tensioning pulley 41 ensures the synchronous rotation of the driven shaft 38 and the multiple camshafts 35, resulting in coordinated vibration of each storage disc 8 and improving the stability and reliability of the device. The installation of stabilizer 43 further enhances the rotational stability of camshaft 35, reduces the impact of vibration on the device structure, and extends the device's service life. Overall, the introduction of a vibration-driven mechanism significantly optimizes the sterilization process, enabling the device to complete disinfection tasks more efficiently and thoroughly, meeting the high-precision, high-standard disinfection requirements of medical facilities and other medical devices.

A rectangular column 45 is slidably installed on the suspended arm 44, and the height can be adjusted. A limited discharge plate 46 is fixedly installed on the top of the rectangular column 45, and the limited discharge plate 46 is arranged corresponding to the drainage hole 10. The limited discharge plate 46 and the bottom of the storage circular plate 8 have a drainage gap, and the drainage gap changes with the movement of the storage circular plate 8. A fixing bolt 47 is installed on one side of the suspension arm 44 located at the operating port, and the end of the fixing bolt 47 conflicts with the rectangular column 45, and is used to fix the rectangular column 45 and adjust the distance between the limited discharge plate 46 and the bottom of the storage circular plate 8.

[0061] In this embodiment, in order to optimize the drainage process of the sterilization and disinfection equipment, a drainage control device is specially designed. Specifically, a plurality of suspended arms 44 are fixedly installed on the inner wall of the disinfection space, and these suspended arms 44 extend to the bottom of the drainage holes 10 of the plurality of storage circular plates 8 respectively. A rectangular column 45 is slidably installed on the suspended arm 44, and the height of the rectangular column 45 can be adjusted as needed.

In actual operation, by adjusting the height of the rectangular column 45, the size of the drainage gap between the drainage limiting piece 46 and the bottom of the storage circular plate 8 can be changed, thereby controlling the drainage speed and flow rate to meet different disinfection process requirements.

[0062] The drainage control device designed in this embodiment brings significant optimization effects to the drainage process of the sterilization and disinfection equipment. The height adjustability of the rectangular column 45 allows the drainage gap between the limiting plate 46 and the bottom of the storage circular plate 8 to be flexibly adjusted according to actual needs. This adjustability enables the equipment to adapt to different disinfectant viscosities and drainage requirements, thereby improving the versatility and adaptability of the equipment. By precisely controlling the drainage gap, the drainage speed and flow rate can be effectively adjusted, avoiding excessive drainage, so that the disinfectant forms a thinner solution thickness on the storage circular plate 8 that is suitable for the disinfection of the equipment at this position, ensuring that each equipment can be fully and evenly disinfected. In actual operation, according to the type of equipment and disinfection requirements, the height of the rectangular column 45 is adjusted by fixing the bolt 47, and then the spacing between the limiting plate 46 and the bottom of the storage circular plate 8 is adjusted to achieve fine control of the drainage process.

A threaded column 51 is fixedly installed on the top of at least one limiting disc 50, and an L-shaped connecting frame 52 is slidably sleeved on at least one threaded column 51. The bottom of the L-shaped connecting frame 52 extends to the top of the storage circular plate 8 between the inner cylinder 5 and the outer cylinder 6 and is fixedly installed with an elastic limiting strip 53 for cooperating with the storage circular plate 8 To limit the displacement of items to be sterilized, a threaded sleeve on the threaded column 51 is provided with a height limiting nut 54 and a support nut 55, which are respectively located above and below the L-shaped connecting frame 52, and are used to adjust the height of the L-shaped connecting frame 52 on the threaded column 51, thereby adjusting the distance between the elastic limit strip 53 and the storage circular plate 8. Correspondingly, a positioning ring 56 located outside the support column 4 is provided above the inner cylinder 5, and the inner wall of the positioning ring 56 does not contact the outer surface of the support column 4. An ear piece 57 is fixedly installed on the top of the positioning ring 56, and the ear piece 57 is fixedly connected to the inner wall of the sterilization box 1 by a suspended hanger 58. A plurality of positioning holes 59 are opened on the positioning ring 56, and a bolt seat 60 is fixedly installed on the top of the threaded column 51. , the bolt seat 60 is smaller than the diameter of the threaded column 51, and a positioning bolt 61 is threadedly installed on the bolt seat 60, and the positioning bolt 61 is connected to the positioning hole 59 at the corresponding position to locate the position of the threaded column 51. A displacement ring groove 62 is provided on the inner wall of the movable ring groove 48, and a plurality of positioning grooves 63 are provided on the top inner wall of the displacement ring groove 62. A connecting piece 64 fixedly connected to the adjusting column 49 is slidably installed in the displacement ring groove 62, and a positioning column 65 is fixedly installed on the top of the connecting piece 64. The diameter of the positioning column 65 is less than or equal to the height of the positioning groove 63, the thickness of the connecting piece 64 is equal to the height of the positioning column 65, and the thickness of the connecting piece 64 is half the height of the displacement ring groove 62. 4 and the height of the positioning column 65 is less than or equal to the height of the positioning groove 63, so that when the positioning bolt 61 is inserted into the positioning hole 59, the connecting piece 64 is located above the displacement ring groove 62, and the positioning column 65 is inserted into the positioning groove 63. At this time, there is a gap between the bottom of the adjusting column 49 and the bottom inner wall of the movable ring groove 48 that is consistent with the thickness of the connecting piece 64, and there is also a gap between the bottom of the limiting disc 50 and the top of the inner cylinder 5 that is consistent with the thickness of the connecting piece 64. During adjustment, the positioning bolt 61 is disengaged from the positioning hole 59, the threaded column 51 and the adjusting column 49 move downward, the bottom of the limiting disc 50 contacts the top of the inner cylinder 5, the bottom of the adjusting column 49 contacts the bottom inner wall of the movable ring groove 48, and the bottom of the connecting piece 64 contacts the bottom inner wall of the displacement ring groove 62.The positioning column 65 is separated from the positioning groove 63. At this time, the adjustment column 49 can be moved along the movable ring groove 48 to adjust the position of the elastic limiting strip 53.

[0064] In this embodiment, to ensure stable placement of items during the sterilization process and prevent excessive displacement of items due to vibration or liquid flow, multiple inner cylinders 5 are equipped with an item restraint mechanism. The item restraint mechanism in this embodiment significantly optimizes the sterilization and disinfection equipment. First, the adjustment column 49 and the limiting disc 50 within the movable annular groove 48, as well as the L-shaped connecting bracket 52 and the elastic limiting strip 53 on the threaded column 51, effectively restrain items on the storage disc 8. The elastic limiting strip 53 can be lightly pressed against the equipment or not contact it, leaving sufficient clearance for the storage disc 8 to vibrate and the equipment to reciprocate up and down. This design prevents excessive displacement of items during vibration or liquid flow. Second, the provision of the height-limiting nut 54 and the support nut 55 allows for adjustable height of the L-shaped connecting bracket 52, thereby flexibly adjusting the spacing between the elastic limiting strip 53 and the storage disc 8 to accommodate items of varying heights. This adjustability enhances the versatility and adaptability of the equipment, enabling it to meet diverse disinfection needs. Furthermore, the design of the positioning ring 56, lug 57, and suspension rod 58 provides stable support for the object restraint mechanism, ensuring its stability during operation. The alignment of the positioning bolt 61 with the positioning hole 59, and the sliding of the connecting piece 64 and positioning column 65 within the displacement ring groove 62 and positioning groove 63, allow the position of the adjustment column 49 to be precisely fixed, further enhancing the reliability of the object restraint mechanism. Overall, the design of the object restraint mechanism not only improves the disinfection effectiveness of the device, but also enhances its stability and reliability, reducing problems such as incomplete disinfection or equipment failure caused by object displacement.
