[0018] Beneficial effects

[0019] The technical solution provided by the present invention has the following beneficial effects compared with the prior art:

[0020] 1. In the disinfection device for urological surgical instruments of the present invention, a steam generation chamber is arranged inside the disinfection box, and an instrument loading assembly is arranged inside the disinfection box. High-temperature steam is used to kill the germs on the urological surgical instruments in the loading box. By arranging a stirring assembly inside the steam generation chamber, the driving rod is driven to rotate by a motor. When the driving rod rotates, the stirring rod is driven to rotate, so that the stirring rod drives the stirring blades to rotate, thereby agitating the water in the steam generation chamber, making the temperature of the water in the steam generation chamber more evenly distributed, accelerating the water heating process, and then accelerating the time to generate high-temperature steam, improving the disinfection efficiency of the high-temperature steam. At the same time, when the driving rod rotates, it will drive the sphere to reciprocally squeeze and push the movable plate, so that the movable plate reciprocally moves up and down, and then the T-shaped rod reciprocally moves up and down, realizing that the T-shaped rod can reciprocally move up and down while rotating. Thus, the thorn column can fully pierce the bubbles generated when the water in the steam generation chamber is heated, reducing the risk of violent boiling, making the heating process more stable, and further improving the disinfection efficiency of the high-temperature steam. This solves the technical problem in the prior art that the disinfection efficiency of high-temperature steam is relatively low due to the single high-temperature steam disinfection method.

[0021] 2. In the disinfection device for urological surgical instruments of the present invention, a steam reuse assembly is arranged inside the disinfection box. High-temperature steam enters the third pipe through the air inlet bell mouth. The high-temperature steam is converted into condensed water by the condensation device inside the third pipe. The condensed water enters the water collection cavity of the second pipe from the bottom of the third pipe. Since the condensed water in the water collection cavity is increasing, the water collection cavity communicates with the water passing cavity, and then the condensed water flows back into the steam generation chamber through the first pipe again, cooling the hot water in the steam generation chamber and also supplementing the water volume in the steam generation chamber, improving the utilization rate of the device.

[0022] 3. In the disinfection device for urological surgical instruments of the present invention, by setting the instrument loading assembly to cooperate with the steam reuse assembly, when the condensed water in the water collection cavity is increasing, the second pipe will slide downward inside the first pipe, and the second pipe drives the rack to move downward synchronously. During the downward movement of the rack, it will engage with the gear and cause the gear to rotate half a turn, so that the loading box is flipped 180 degrees, and then the urological surgical instruments in the loading box are flipped 180 degrees, making the other side of the urological surgical instruments in the loading box face the flow direction of the high-temperature steam, so that the urological surgical instruments in the loading box can be fully disinfected by the high-temperature steam, further improving the disinfection efficiency of the high-temperature steam.

[0075] All other structures are the same as those in the first embodiment.

[0076] The working principle and usage process of the embodiment of the present invention:

[0077] First, start the motor in the power box 32. The motor drives the driving rod 33 to rotate. When the driving rod 33 rotates, it drives the stirring rod 320 to rotate, so that the stirring rod 320 drives the stirring blades 321 to rotate, thereby stirring the water in the steam generating chamber 12, making the temperature of the water in the steam generating chamber 12 more evenly distributed, accelerating the heating process of the water, and then accelerating the time to generate high-temperature steam, improving the disinfection efficiency of the high-temperature steam;

[0078] When the driving rod 33 rotates, it will drive the two connecting plates 316 to rotate. The connecting plates 316 drive the movable plate 312 to rotate around the driving rod 33 through the connecting rod 317 (at this time, the driving rod 33 rotates inside the through hole three at the center of the movable plate 312). When the movable plate 312 rotates, it drives the sealing box 34, the sealing plate 313, and the T-shaped rod 318 to rotate synchronously (when the movable plate 312 rotates, it can drive the sealing box 34 to rotate together by the two ends of the movable plate 312 abutting against the inner wall of the through groove 311);

[0079] When the driving rod 33 rotates, it drives the first bevel gear 35 to rotate. When the first bevel gear 35 rotates, it drives the second bevel gear 38 to rotate. When the second bevel gear 38 rotates, it drives the rotating rod 37 to rotate. When the rotating rod 37 rotates, it drives the straight rod 39 to rotate around the rotating rod 37 as the center, so that the sphere 310 reciprocally squeezes and pushes the movable plate 312 (when the straight rod 39 is in the vertical state, the sphere 310 squeezes the movable plate 312 to move upward, the first spring 314 is compressed, and the first telescopic rod 315 shortens; when the straight rod 39 is in the horizontal state, the contraction force of the first spring 314 resets the movable plate 312 and the first telescopic rod 315), thereby making the movable plate 312 reciprocally move up and down. When the movable plate 312 reciprocally moves up and down, it drives the sealing plate 313 to reciprocally move up and down. When the sealing plate 313 reciprocally moves up and down, it drives the T-shaped rod 318 to reciprocally move up and down. Thus, it realizes that the T-shaped rod 318 can reciprocally move up and down while rotating, and further enables the thorn column 319 to fully pierce the bubbles generated when the water in the steam generation cavity 12 is heated (the water level in the steam generation cavity 12 changes at all times, and the temperature of the heated water also changes at all times. Therefore, the height of the water bubbles also changes at all times. Therefore, the reciprocating up and down movement of the T-shaped rod 318 enables the thorn column 319 to fully pierce the bubbles generated when the water in the steam generation cavity 12 is heated), which can reduce the risk of violent boiling, make the heating process more stable, and further improve the disinfection efficiency of high-temperature steam;

[0080] High-temperature steam can flow from below the loading box 21 to above the loading box 21 through the filter holes 22. The high-temperature steam enters the third pipe body 45 from the air inlet bell mouth 46. The high-temperature steam is converted into condensed water by the condensation device inside the third pipe body 45. The condensed water enters the water collection cavity 419 of the second pipe body 44 from the bottom of the third pipe body 45 (at this time, the third spring 420 is in the natural state, so that the end of the piston plate 417 away from the straight plate 418 abuts against the inner wall of the second pipe body 44, thereby isolating the water collection cavity 419 from the water passing cavity 429, and further making the water collection cavity 419 and the water passing cavity 429 not communicate with each other). The medical filter element inside the water collection cavity 419 filters impurities and microorganisms in the condensed water;

[0081] When the condensate water in the water collection cavity 419 increases, the second pipe body 44 will slide downward inside the first pipe body 43, causing the positioning plate 47 to move downward, and further compressing the second spring 48 (the second telescopic rod 49 shortens). The downward sliding of the second pipe body 44 will drive the sealing pipe 416, the piston plate 417, the straight plate 418, the L-shaped rod 427, and the rack 428 to move downward synchronously. During the downward movement of the rack 428, it will engage with the gear 26. The downward movement of the rack 428 causes the gear 26 to rotate half a circle, and further flips the loading box 21 by 180 degrees. Then, the urological surgical instruments in the loading box 21 are flipped by 180 degrees, so that the other side of the urological surgical instruments in the loading box 21 faces the flowing direction of the high-temperature steam, and further enables the urological surgical instruments in the loading box 21 to be fully disinfected by the high-temperature steam, further improving the disinfection efficiency of the high-temperature steam;

[0082] After the loading box 21 is flipped by 180 degrees, since the condensate water in the water collection cavity 419 will still increase, the rack 428 continues to move downward driven by the second pipe body 44, causing the rack 428 to separate from the gear 26. At this time, since the distance between the positioning plate 47 and the second support plate 413 is relatively close, the fourth magnetic plate 415 generates a magnetic attraction force on the second magnetic plate 411, causing the second pipe body 44 to slide downward at an accelerated speed. When the fourth magnetic plate 415 contacts the second magnetic plate 411, the second pipe body 44 stops sliding downward. At this time, the straight plate 418 is located on one side of the support frame plate 424;

[0083] When the straight plate 418 is located on one side of the support frame plate 424 (at this time, the support frame plate 424 is at the lowest position under the action of gravity), the fifth magnetic plate 425 generates a magnetic attraction force on the sixth magnetic plate 426, causing the straight plate 418 to move towards the support frame plate 424 (the third spring 420 is stretched, and the third telescopic rod 421 is elongated), and further causing the piston plate 417 to move towards the support frame plate 424 until the fifth magnetic plate 425 contacts the sixth magnetic plate 426 (at this time, the rack 428 has moved a certain distance towards the support frame plate 424. Therefore, when the rack 428 moves upward, the rack 428 will not engage with the gear 26), enabling the water collection cavity 419 and the water passing cavity 429 to communicate with each other. Then, the condensate water in the water collection cavity 419 flows downward into the water passing cavity 429 (the medical filter element inside the water passing cavity 429 filters the impurities and microorganisms in the condensate water). Finally, the condensate water flows back into the steam generation cavity 12 through the first pipe body 43, cooling the hot water in the steam generation cavity 12 and also supplementing the water volume in the steam generation cavity 12, improving the utilization rate of the device;

[0084] When the condensed water in the water collection cavity 419 flows into the steam generation cavity 12 through the first pipe body 43, the weight of the second pipe body 44 becomes lighter and lighter. At this time, due to the tension of the second spring 48, the positioning plate 47 moves upward, and then the second pipe body 44 moves upward. At this time, since the fifth magnetic plate 425 and the sixth magnetic plate 426 are magnetically attracted and in contact with each other, the fifth magnetic plate 425 and the sixth magnetic plate 426 are firmly magnetically attracted to form a whole, and then the support frame plate 424 and the straight plate 418 are firmly integrated. Since the straight plate 418 moves upward synchronously with the second pipe body 44, the support frame plate 424 moves upward synchronously with the second pipe body 44. When the support frame plate 424 moves to the highest position, the top of the support frame plate 424 contacts the limit plate 422 above the guide rail 423, so that the support frame plate 424 cannot continue to move upward;

[0085] When the support frame plate 424 cannot continue to move upward, at this time, the positioning plate 47 is relatively close to the first support plate 412, and the third magnetic plate 414 generates a magnetic attraction force on the first magnetic plate 410 to accelerate the upward sliding of the second pipe body 44 until the third magnetic plate 414 contacts the first magnetic plate 410, and the upward sliding of the second pipe body 44 stops (at this time, the second spring 48 is still in a compressed state and the second spring 48 still has an upward tension), and at this time, the sixth magnetic plate 426 is separated from the fifth magnetic plate 425, and the support frame plate 424 slides downward along the guide rail 423 due to gravity until the bottom of the support frame plate 424 contacts the limit plate 422 below the guide rail 423, realizing the reset of the support frame plate 424.

[0086] In summary, by arranging a stirring assembly 3 inside the steam generation chamber 12, starting the motor in the power box 32, the motor drives the driving rod 33 to rotate. When the driving rod 33 rotates, it drives the stirring rod 320 to rotate, causing the stirring rod 320 to drive the stirring blades 321 to rotate, thereby agitating the water in the steam generation chamber 12. As a result, the temperature of the water in the steam generation chamber 12 is more evenly distributed, accelerating the water heating process, and thus accelerating the time to generate high-temperature steam, improving the disinfection efficiency of the high-temperature steam. At the same time, when the driving rod 33 rotates, it drives the sphere 310 to reciprocally squeeze and push the movable plate 312, causing the movable plate 312 to reciprocally move up and down. As a result, the T-shaped rod 318 reciprocally moves up and down, achieving that the T-shaped rod 318 can reciprocally move up and down while rotating. Thus, the thorn column 319 can fully pierce the bubbles generated when the water in the steam generation chamber 12 is heated, reducing the risk of violent boiling and making the heating process more stable, further improving the disinfection efficiency of the high-temperature steam. By arranging a steam reuse assembly 4 inside the disinfection box 1, the high-temperature steam enters the third pipe 45 through the intake bell mouth 46. The high-temperature steam is converted into condensed water by the condensation device inside the third pipe 45. The condensed water enters the water collection cavity 419 of the second pipe 44 from the bottom of the third pipe 45. Since more and more condensed water accumulates in the water collection cavity 419, the water collection cavity 419 communicates with the water passing cavity 429, and then the condensed water flows back into the steam generation chamber 12 through the first pipe 43 again, cooling the hot water in the steam generation chamber 12 and replenishing the water volume in the steam generation chamber 12, improving the utilization rate of the device. By arranging the instrument loading assembly 2 to cooperate with the steam reuse assembly 4, when more and more condensed water accumulates in the water collection cavity 419, the second pipe 44 slides downward inside the first pipe 43, driving the rack 428 to move downward synchronously. During the downward movement of the rack 428, it meshes with the gear 26 and causes the gear 26 to rotate half a turn, thereby flipping the loading box 21 by 180 degrees, and then flipping the urological surgical instruments in the loading box 21 by 180 degrees, so that the other side of the urological surgical instruments in the loading box 21 faces the flow direction of the high-temperature steam, enabling the urological surgical instruments in the loading box 21 to be fully disinfected by the high-temperature steam, further improving the disinfection efficiency of the high-temperature steam.
