Description

Technical Field

[0001] This invention relates to the field of thermal sterilization equipment technology, and in particular to a water bath sterilization energy-saving device. Background Technology

[0002] Industrial production requires the rapid sterilization of large quantities of products. Water bath sterilization technology, leveraging the uniform heat conduction of water, can sterilize medical devices, food, and liquid pharmaceuticals while preserving the product's shape. Traditional water bath sterilization equipment uses static placement frames, fixing materials in place. Materials in static frames (such as bagged food and ampoules) tend to accumulate due to gravity, creating narrow gaps that obstruct water flow. This leads to "dead zones" in the corners of the sterilization chamber and between materials, resulting in localized temperature deviations of ±2°C. Consequently, while the surface of the materials is thoroughly sterilized, the interior and corners remain incompletely sterilized. Traditional water bath sterilization equipment primarily uses high-temperature hot water spray sterilization and low-temperature cold water spray cooling. During active cooling, room-temperature cold water replaces the residual heat inside the sterilization chamber, and the heat carried away during discharge is completely lost, further contributing to high energy consumption and low energy efficiency. Summary of the Invention

[0014] (3) Beneficial effects 1. The motor drives the active bevel gear to rotate via the output shaft. The active bevel gear drives the first driven bevel gear and the second driven bevel gear to rotate clockwise and counterclockwise respectively via the side teeth. The first driven bevel gear and the second driven bevel gear drive the rotating shaft to rotate clockwise and counterclockwise reciprocally. The rotating shaft has a thread on the outside and two rectangular wedges are symmetrically provided at the upper end of the rotating shaft. Two guide limit grooves are provided on the rotating shaft corresponding to the lower part of the thread. The upper end of the rotating shaft is threaded with a mounting nut and a washer through the threaded hole. The rotating shaft drives the material placement component to rotate clockwise and counterclockwise reciprocally via the two rectangular wedges. The material placement component drives the items to be sterilized inside to rotate clockwise and counterclockwise reciprocally, so that the items to be sterilized and the high temperature water form forced convection, which further improves the sterilization uniformity and efficiency and avoids sterilization dead zones.

[0015] 2. When the mounting base is fixed to the upper part of the support plate by installing nuts and washers, the mounting base pushes the abutment plates on both sides downward. The abutment plates drive the movable ring and the second limiting wedge to move downward along the guide limiting groove via the movable guide key. Furthermore, the second limiting wedge and the first limiting wedge separate and engage. Thus, when the sterilization chamber drives the material placement component on the upper side to rotate back and forth, the rotating seat and its outer cleaning rod are statically idle. When cleaning the inner wall of the sterilization chamber, turn the mounting nut counterclockwise to remove the mounting nut and washers. Further, remove the mounting base from the rotating shaft. Thus, the flat wire spring releases its elastic potential energy and pushes the movable ring upward, driving the movable guide key and the abutment plate to move upward along the guide limiting groove. The movable ring drives the second limiting wedge to move upward and engage with the material placement component. When the first limiting wedge is engaged, the motor is turned on via the operation screen. The motor drives the active bevel gear to rotate via the output shaft. The active bevel gear drives the first driven bevel gear and the second driven bevel gear to rotate clockwise and counterclockwise respectively via the side teeth. The first driven bevel gear and the second driven bevel gear drive the rotating shaft to rotate clockwise and counterclockwise reciprocally. The rotating shaft drives the movable ring to rotate reciprocally via the guide limiting groove and the movable guide key. The movable ring drives the rotating seat to rotate reciprocally via the second limiting wedge and the first limiting wedge. The rotating seat drives the outer cleaning rod to clean the inner wall of the sterilization chamber. The reciprocating rotation component can drive the material placement component and the cleaning rod to rotate "time-sharingly", so that the material placement component and the cleaning rod perform their respective functions and avoid interference between their rotation.

[0016] 3. The splicing seats at the bottom of the placement frame correspond one-to-one with the bow-shaped frames. The mounting base can install the placement frame through multiple bow-shaped frames and fixing blocks. Arrange the remaining placement frames in sequence. When the upper placement frame is installed downwards, the weight of the placement frame pushes the upper support block downwards to the contact block. The contact block drives the fixing plate to squeeze the return spring through the movable rod. At the same time, the movable rod pushes the movable block downwards. The movable block pushes the movable blocks on both sides to open through the curved grooves on both sides and the fixing rod. Thus, the fixing blocks on the same side limit the placement frame by limiting the movable blocks. Use the handle to open the top cover. The body is placed on top of the uppermost placement frame via a support block and splicing seat. By rotating the knob clockwise, the knob drives the movable plate downward through the rotating screw. The movable plate drives the movable crossbar downward along the guide groove opened in the fixed sleeve. The movable crossbar pushes the movable block downward through the movable rod. The movable block pushes the movable locking blocks on both sides open through the curved grooves on both sides and the fixed rod, thereby limiting the installation of the upper cover body and the upper placement frame. Each placement frame is precisely locked by the upper connecting component during installation, preventing the placement frame from hitting the inner wall of the sterilization chamber due to centrifugal force or water flow impact.

[0017] 4. The placement frame is equipped with a placement tray or placement baffle by four splicing seats. The upper part of the placement frame is equipped with a handle. The placement frame, placement baffle and mounting base are all equipped with water holes. The staff can install the corresponding placement tray or placement baffle according to the actual needs. The sterilization hot water inside the sterilization chamber enters the placement frame through the water holes to sterilize the items. Attached Figure Description

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] A water bath sterilization energy-saving device, such as Figures 1-10 As shown, it includes an insulated box 1. Inside the insulated box 1, a sterilization box 103 and a reciprocating rotating component 2 are provided through a horizontal partition 101. Inside the sterilization box 103, a material placement component 3 is provided for placing items to be sterilized. A sealing component 4 is provided on the upper part of the material placement component 3 to prevent items from falling. A water circulation component 5 is provided on one side of the insulated box 1. The water circulation component 5 is provided with a waste heat recovery closed-loop circulation component 6 through a floor mounting frame 501. The reciprocating rotation assembly 2 includes a motor 201 mounted on the bottom of the insulated box 1 via a support. The output end of the motor 201 is provided with a driving bevel gear 202, with teeth at its upper half. The upper and lower ends of the driving bevel gear 202 are respectively provided with a first driven bevel gear 203 and a second driven bevel gear 204. A rotating shaft 205 is coaxially connected to the first driven bevel gear 203 and the second driven bevel gear 204, extending upwards into the sterilization box 103. The motor 201 drives the driving bevel gear 202 to rotate via the output shaft. The driving bevel gear 202, through its side teeth, sequentially drives the first driven bevel gear 203 and the second driven bevel gear 204 to rotate clockwise and counterclockwise, respectively. 03. The second driven bevel gear 204 drives the rotating shaft 205 to rotate clockwise and counterclockwise. The rotating shaft 205 has a thread on its outer side. Two rectangular wedges 206 are symmetrically arranged on the upper end of the rotating shaft 205. Two guide and limiting grooves 207 are opened on the rotating shaft 205 corresponding to the lower part of the thread. The upper end of the rotating shaft 205 is threaded with a mounting nut 217 and a washer 218 through a threaded hole. The rotating shaft 205 drives the material placement component 3 to rotate clockwise and counterclockwise through the two rectangular wedges 206. The material placement component 3 drives the items to be sterilized inside it to rotate clockwise and counterclockwise, so that the items to be sterilized and the high temperature water form forced convection, further improving the sterilization uniformity and avoiding sterilization dead corners. A rotating seat 208 is fitted inside the sterilization chamber 103 on the rotating shaft 205. The rotating seat 208 has a movable cavity inside. Multiple first limiting wedges 210 are evenly arranged circumferentially at the upper end of the movable cavity. A flat wire spring 211 and a movable ring 212 are fitted inside the movable cavity on the rotating shaft 205. Multiple second limiting wedges 213 corresponding to the first limiting wedges 210 are evenly arranged circumferentially on the side of the movable ring 212. Two movable guide keys 214 are symmetrically arranged in two guide limiting grooves 207 on the inner side of the movable ring 212. Each movable guide key 214 has a contact plate 215 at its upper end. A contact plate 215 is evenly arranged on the outer side of the rotating seat 208 to the sterilization chamber 103. Four cleaning rods 216 are used to clean the inner wall of the sterilizer 103. A support plate 209 is fixedly installed on the upper part of the rotating seat 208 on the rotating shaft 205. The support plate 209 has a groove with a corresponding contact plate 215 at its upper end. When the mounting base 301 is fixed to the upper part of the support plate 209 by the mounting nut 217 and the washer 218, the mounting base 301 pushes the contact plates 215 on both sides downward. The contact plates 215 drive the movable ring 212 and the second limiting wedge 213 to move downward along the guide limiting groove 207 through the movable guide key 214. Furthermore, the second limiting wedge 213 and the first limiting wedge 210 separate and engage. When cleaning the inner wall of the sterilizer 103, the reverse direction is reversed. Rotate the mounting nut 217 to remove the mounting nut 217 and washer 218, and then remove the mounting base 301 from the rotating shaft 205. This releases the elastic potential energy of the flat wire spring 211, pushing the movable ring 212 upwards, causing the movable guide key 214 and the contact plate 215 to move upwards along the guide limiting groove 207. The movable ring 212 then causes the second limiting wedge 213 to move upwards and mesh with the first limiting wedge 210. At this time, the motor 201 is turned on via the operation screen. The motor 201 drives the driving bevel gear 202 to rotate via the output shaft. The driving bevel gear 202, through its side teeth, sequentially drives the first driven bevel gear 203 and the second driven bevel gear 204 clockwise. The clockwise and counterclockwise rotation of the rotating shaft 205 causes the first driven bevel gear 203 and the second driven bevel gear 204 to rotate clockwise and counterclockwise. The rotating shaft 205 drives the movable ring 212 to rotate clockwise and counterclockwise through the guide limit groove 207 and the movable guide key 214. The movable ring 212 drives the rotating seat 208 to rotate clockwise and counterclockwise through the second limit wedge 213 and the first limit wedge 210. The rotating seat 208 drives the outer cleaning rod 216 to clean the inner wall of the sterilization chamber 103. The reciprocating rotation component 2 can drive the material placement component 3 and the cleaning rod 216 to rotate in a "time-sharing" manner, so that the material placement component 3 and the cleaning rod 216 can each perform their respective functions and avoid interference between their rotation.

[0024] like Figure 2 , Figure 6 , Figure 7As shown, the material placement assembly 3 includes a mounting base 301, which is placed on the rotating shaft 205 by a rectangular wedge 206. The mounting base 301 is also mounted on the support plate 209 by a mounting nut 217 and a washer 218. Multiple curved support plates 302 are evenly arranged on the upper edge of the mounting base 301. An arc-shaped frame is provided between each curved support plate 302, and a fixing block 305 is provided between the openings of each arc-shaped frame. Multiple placement frames 303 are sequentially placed on the upper part of the mounting base 301. Four splicing seats 304 are evenly arranged on each placement frame 303. The splicing seats 304 at the bottom of the placement frame 303 correspond one-to-one with the arc-shaped frames. The mounting base 301 can install the placement frames 303 by means of multiple arc-shaped frames and fixing blocks 305.

[0025] like Figure 6 , Figure 7 As shown, the splicing base 304 has an installation opening with two fixing blocks 305. A rectangular cavity is formed inside the splicing base 304, containing a return spring 306 and a fixing plate 307 that cover the movable rod 308. The movable rod 308 extends vertically through the splicing base 304 and has a contact block 309 at its top. A connecting assembly is provided at the lower part of the placement frame 303 corresponding to the lower part of each splicing base 304. The connecting assembly includes a support block 310, which has a sliding cavity inside. Sliding through holes communicating with the sliding cavity are formed on both sides of the support block 310. The end of the movable rod 308 extends downward into the sliding cavity and has a movable block 311 at its end. Two curved sections are symmetrically formed on the movable block 311. The two curved grooves 312 are connected to movable locking blocks 314 by fixed rods 313. The two movable locking blocks 314 are movably connected in the sliding through hole. The remaining placement frames 303 are arranged in sequence. When the upper placement frame 303 is installed downward, the upper support block 310 pushes the contact block 309 downward by the weight of the placement frame 303. The contact block 309 drives the fixed plate 307 to squeeze the reset spring 306 through the movable rod 308. At the same time, the movable rod 308 pushes the movable block 311 downward. The movable block 311 pushes the movable locking blocks 314 on both sides to open through the curved grooves 312 and fixed rods 313 on both sides. Thus, the fixed locking block 305 on the same side limits the placement frame 303 by limiting the movable locking block 314.

[0026] like Figure 7 , Figure 8As shown, the placement frame 303 is equipped with a placement tray 315 or a placement baffle 316 via four splicing seats 304. A handle is provided on the upper part of the placement frame 303. Water holes are provided in the placement frame 303, the placement baffle 316 and the mounting base 301. The staff can install the corresponding placement tray 315 or placement baffle 316 according to actual needs. The sterilization hot water inside the sterilization chamber 103 enters the placement frame 303 through the water holes to sterilize the items.

[0027] like Figure 2 , Figure 6 , Figure 9 As shown, the sealing assembly 4 includes an upper cover 401 with two handles and multiple fan-shaped through holes. A rotating knob 402 is located on the upper part of the upper cover 401, and the knob 402 is movably connected to a movable disc 404 via a rotating shaft. A fixing sleeve 405 is located on the lower part of the upper cover 401 corresponding to the outer side of the movable disc 404. Four movable crossbars 406 are located on the outer side of the movable disc 404. A sliding groove is provided on the fixing sleeve 405 corresponding to each movable crossbar 406. A connecting component is provided at the end of each movable crossbar 406, and a support block 310 in the connecting component is fixedly connected to the upper cover 401. The upper cover 401 is placed on the uppermost placement frame 303 via the support block 310 and splicing seat 304 through the handle. By rotating the knob 402 clockwise, the knob 402 drives the movable plate 404 to move downward through the rotating screw 403. The movable plate 404 drives the movable crossbar 406 to move downward along the guide groove opened in the fixed sleeve 405. The movable crossbar 406 pushes the movable block 311 downward through the movable rod 308. The movable block 311 pushes the movable locking blocks 314 on both sides to open through the curved grooves 312 on both sides and the fixed rod 313, thereby limiting the installation of the upper cover 401 and the upper placement frame 303.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 11 As shown, the sterilization chamber 103 has two collection slots at its bottom, through which solid particulate waste inside the sterilization chamber 103 can be collected. The insulated chamber 1 is equipped with an operation screen 102 for controlling electrical components. A sealing cover 104 is hinged to the upper part of the insulated chamber 1. A sealing strip 105 for sealing the insulated chamber 1 is provided along the edge of the inner part of the sealing cover 104. A sealing ring 106 for sealing the sterilization chamber 103 is provided at the lower part of the sealing cover 104 corresponding to the upper part of the sterilization chamber 103. From left to right, a steam inlet 107, a water spray nozzle 109, and a detection device 108 are provided between the lower part of the sealing cover 104 and the sealing ring 106. A door lock device is provided on the front of the sealing cover 104 and the sterilization chamber 103. A handle is provided on the front of the sealing cover 104. The door lock device can lock the sealing cover 104 and the sterilization chamber 103.

[0029] like Figure 1 , Figure 10 As shown, the water circulation component 5 includes a floor-mounted frame 501. The first layer of the floor-mounted frame 501 is equipped with a controller 502 and a first water pump 503. The second layer of the floor-mounted frame 501, from left to right, is equipped with a hot water tank 505, a second water pump 504, and a cold water tank 507. The hot water tank 505 is equipped with a heater 506. The cold water tank 507 and the hot water tank 505 are respectively equipped with water inlets. The heater 506 can heat the water inside the hot water tank 505. The first water pump 503 can pump the water inside the sterilization chamber 103 into the cold water tank 507 or the hot water tank 505. The second water pump 504 can pump the water inside the cold water tank 507 or the hot water tank 505 into the sterilization chamber 103.

[0030] like Figure 10 As shown, the waste heat recovery closed-loop circulation component 6 includes a compressor 601, an evaporator 602, and a condenser 603. The evaporator 602 and the condenser 603 are respectively located inside the cold water tank 507 and the hot water tank 505. The warm water inside the sterilization chamber 103 is drawn into the cold water tank 507 through a water pipe, and the compressor 601 is turned on. As the compressor 601 works, the evaporator 602 absorbs the waste heat inside the cold water tank, and the compressor compresses the steam inside the evaporator 602, so that the steam is liquefied in the condenser 603 and releases heat in the hot water tank 505, thereby further realizing the full recycling of the cold and hot water sources and high-efficiency energy saving.

[0031] like Figure 1 , Figure 10 As shown, the two collection tanks at the bottom of the sterilization chamber 103 are connected to the drain pipe and the first water pump 503 respectively through water pipes and two solenoid valves. The first water pump 503 is connected to the hot water tank 505 and the cold water tank 507 respectively through water pipes and two solenoid valves. The second water pump 504 connects the hot water tank 505 and the cold water tank 507 to the spray nozzle 109 through water pipes and two solenoid valves. Through the cooperation of the solenoid valves and the first water pump 503, the water inside the sterilization chamber 103 can be accurately drawn into the cold water tank 507, or the cleaning wastewater inside the sterilization chamber 103 can be discharged. Through the cooperation of the solenoid valves and the second water pump 504, the water inside the hot water tank 505 and the cold water tank 507 can be accurately drawn into the sterilization water.

[0032] like Figure 1 , Figure 10As shown, the operation screen 102 is electrically connected to the motor 201, the detection device 108, the heater 506, and the controller 502. The controller 502 is electrically connected to the first water pump 503, the second water pump 504, the compressor 601, and each solenoid valve. The operation screen 102 can control the motor 201, the detection device 108, the heater 506, and the controller 502, making the operation of the equipment more complete.

[0033] Working principle: During sterilization preparation, staff inject water into the hot water tank 505 and cold water tank 507 through the inlet, and heat the water inside the hot water tank 505 by turning on the heater 506 through the operation screen 102. Staff place the items to be sterilized on the corresponding placement frames 303. Next, they install the placement frames 303 onto the mounting base 301 using the handles. The splicing seats 304 at the bottom of the placement frames 303 correspond one-to-one with the arched frames. Further, the remaining placement frames 303 are arranged sequentially. When the upper placement frame 303 is installed downwards, the weight of the placement frame 303 pushes the upper support block 310 downwards, causing the contact block 309 to compress the return spring 306 via the movable rod 308, and simultaneously, the movable rod 308 pushes the movable block 311 downwards. The movable block 311 passes through the curved grooves 312 on both sides and... The fixed rod 313 pushes the movable blocks 314 on both sides to open, so that the fixed blocks 305 on the same side limit the placement frame 303 by limiting the movable blocks 314. After multiple placement frames 303 are placed in sequence, the upper cover 401 is placed on the uppermost placement frame 303 by the handle through the support block 310 and the splicing seat 304. By rotating the knob 402 clockwise, the knob 402 drives the movable plate 404 to move downward through the rotating screw 403. The movable plate 404 drives the movable crossbar 406 to move downward along the guide groove opened in the fixed sleeve 405. The movable crossbar 406 pushes the movable block 311 downward through the movable rod 308. The movable block 311 pushes the movable blocks 314 on both sides to open through the curved grooves 312 on both sides and the fixed rod 313, thereby limiting the installation of the upper cover 401 and the upper placement frame 303.

[0034] After installing the upper cover 401, place the sealing cover 104 onto the insulation box 1 using the handle and close the door lock. Using the operation screen 102, open the second water pump 504 and the corresponding solenoid valve via the controller 502. The second water pump 504 transports the hot water from the hot water tank 505 to the spray nozzle 109 through a water pipe. The spray nozzle 109 sprays the hot water onto the placement tray 315 and into the sterilization box 103. As the water level inside the sterilization box 103 rises, steam is added into the sterilization box 103 through the steam inlet 107 to further heat and pressurize the internal hot water. The water level and pressure inside the sterilization box 103 are monitored in real-time via the detection device 108 on the operation screen 102, allowing for reasonable control of the temperature and pressure inside the sterilization box 103. When the water level inside the sterilization box 103... When the position and pressure reach a suitable range, the second water pump 504 and the corresponding solenoid valve are closed by the controller 502 through the operation screen 102, and the motor 201 is turned on through the operation screen 102. The motor 201 drives the active bevel gear 202 to rotate through the output shaft. The active bevel gear 202 drives the first driven bevel gear 203 and the second driven bevel gear 204 to rotate clockwise and counterclockwise respectively through the side teeth. The first driven bevel gear 203 and the second driven bevel gear 204 drive the rotating shaft 205 to rotate clockwise and counterclockwise. The rotating shaft 205 drives the movable ring 212 and the second limit wedge 213 to rotate back and forth through the guide limit groove 207 and the movable guide key 214. The rotating shaft 205 drives the mounting base 301 and the placement frame 303 to rotate repeatedly through the rectangular wedge 206.

[0035] After sterilization, motor 201 is turned off via operation screen 102, and controller 502 is used to open the first water pump 503 and the corresponding two solenoid valves via operation screen 102. This draws the hot water inside sterilization chamber 103 into hot water tank 505 via water pipe. After the hot water is drawn from sterilization chamber 103, controller 502 is used to turn off the first water pump 503 and the corresponding two solenoid valves via operation screen 102, and opens the second water pump 504 and the corresponding solenoid valve. The second water pump 504 draws cold water from cold water tank 507 into spray nozzle 109 to cool the objects on placement tray 315. After cooling is complete... By using the controller 502 on the operation screen 102, the second water pump 504 and its corresponding solenoid valve are shut off, and the first water pump 503 and its two corresponding solenoid valves are opened. The warm water inside the sterilization chamber 103 is drawn into the cold water tank 507 through the water pipe. After the water is drawn off, the first water pump 503 and its two corresponding solenoid valves are shut off by the controller 502 on the operation screen 102, and the compressor 601 is turned on. As the compressor 601 works, the evaporator 602 absorbs the residual heat inside the cold water tank, and the compressor compresses the steam inside the evaporator 602, so that the steam is liquefied in the condenser 603 and releases heat in the hot water tank 505.

[0036] After the warm water inside the sterilizer 103 is treated, open the door lock and open the sealing cover 104 using the handle. Turn the knob 402 counterclockwise. The knob 402 drives the movable plate 404 upward through the rotating screw 403. The movable plate 404 drives the movable crossbar 406 upward along the guide groove in the fixed sleeve 405. The movable crossbar 406 pulls the movable block 311 upward through the movable rod 308. The movable block 311 pushes the movable locking blocks 314 on both sides inward through the curved grooves 312 on both sides and the fixed rod 313, thereby causing the fixed locking block 305 to lose its restriction on the movable locking block 314. Next, by using the handle, the upper cover 401 is removed from the placement tray 315. As the upper cover 401 separates, the return spring 306 releases its elastic potential energy and pushes the movable rod 308 upward through the fixed plate 307. The movable rod 308 drives the contact block 309 and the movable block 311 to return to their original positions. The movable block 311 pushes the movable locking blocks 314 on both sides to retract inward through the curved grooves 312 on both sides and the fixed rod 313, so that the fixed locking block 305 on the lower side loses its limit on the movable locking block 314. Then, the upper placement frame 303 is removed by using the handle. In summary, each placement tray 315 is removed in sequence.

[0037] When cleaning the sterilizer 103 after prolonged use, remove all the placement frames 303 on the upper side of the mounting base 301, then turn the mounting nut 217 counterclockwise to remove the mounting nut 217 and washer 218. Further remove the mounting base 301 from the rotating shaft 205. This releases the elastic potential energy of the flat wire spring 211, pushing the movable ring 212 upwards, causing the movable guide key 214 and the contact plate 215 to move upwards along the guide limiting groove 207. The movable ring 212 then causes the second limiting wedge 213 to move upwards and mesh with the first limiting wedge 210. Add cleaning fluid into the sterilizer 103. Turn on the motor 201 via the operation screen 102. The motor 201 drives the active bevel gear 202 to rotate via the output shaft. The active bevel gear 202, through its side teeth, sequentially drives... The first driven bevel gear 203 and the second driven bevel gear 204 rotate clockwise and counterclockwise, respectively. The first driven bevel gear 203 and the second driven bevel gear 204 drive the rotating shaft 205 to rotate clockwise and counterclockwise. The rotating shaft 205 drives the movable ring 212 to rotate clockwise and counterclockwise through the guide limit groove 207 and the movable guide key 214. The movable ring 212 drives the rotating seat 208 to rotate clockwise and counterclockwise through the second limit wedge 213 and the first limit wedge 210. The rotating seat 208 drives the outer cleaning rod 216 to clean the inner wall of the sterilization chamber 103. The cleaning rod 216 cleans the scale and solid debris after cleaning into the collection tank. After cleaning, the corresponding solenoid valve is opened by the controller 502 through the operation screen 102, and the cleaning liquid inside the sterilization chamber 103 is discharged through the water pipe.

[0038] After the sterilization chamber 103 is cleaned, the motor 201 is turned off via the operation screen 102, and the mounting base 301 is mounted on the rotating shaft 205 via the rectangular wedge 206. The mounting nut 217 is then rotated clockwise to fix the mounting base 301 to the upper part of the support plate 209 via the mounting nut 217 and the washer 218. As the mounting base 301 is installed, it pushes the abutment plates 215 on both sides downward. The abutment plates 215 drive the movable ring 212 and the second limiting wedge 213 to move downward along the guide limiting groove 207 via the movable guide key 214. Furthermore, the second limiting wedge 213 and the first limiting wedge 210 separate and engage.

[0039] The cleaning brush on the cleaning rod 216 is detachable and can be replaced according to the usage time and effect. The height and size of this sterilization device are not limited during use. This sterilization device can be customized according to the size of different types of sterilized items during production, thereby improving the compatibility of this sterilization device with the items to be sterilized, further ensuring sterilization quality and extending the service life of the equipment.
