[0022] See also Figure 1-4The utility model provides a technical solution: a medical low-temperature steam formaldehyde sterilization cabinet, comprising a main body 1, a sterilization chamber 4 and an installation chamber 3 are sequentially opened on the surface of the main body 1 from top to bottom, and the sterilization chamber 4 is arc-shaped, an upper cabinet door 6 is hinged at the outer edge of the sterilization chamber 4, and a lower cabinet door 5 is hinged at the outer edge of the installation chamber 3. The inner side wall of the sterilization chamber 4 is symmetrically fixedly connected with a fixed block 14, and a rotating component is arranged on the inner side of the fixed block 14. The rotating component includes a storage plate 15, and the storage plate 15 has a built-in driving device. The output shaft of the driving device is drivingly connected with a movable rod 21, and a plurality of equidistantly arranged mounting frames 22 are fixedly connected to the surface of the movable rod 21. A groove 23 is opened on the upper surface of the mounting frame 22, and the center position of the groove 23 is A fixed plate 24 is fixedly connected at the position, and displacement plates 26 are fixedly connected on both sides of the fixed plate 24 through reset springs C25, and the displacement plates 26 slide in a limited position in the groove 23, and a placement hole 27 is opened on the upper surface of the displacement plate 26. Since the sterilization chamber 4 is designed in an arc shape, low-temperature formaldehyde steam will form a backflow when entering the sterilization chamber 4, and the driving device drives the mounting frame 22 to rotate through the movable rod 21, thereby adjusting the angle of the medical test tube in real time according to the direction of the low-temperature formaldehyde steam, so that the tube mouth of the medical test tube is always opposite to the steam direction, so that the low-temperature formaldehyde steam quickly enters the end of the inner wall of the medical test tube for sterilization, so as to adjust the angle of the medical test tube in real time according to the backflow of the low-temperature formaldehyde steam in the sterilization cabinet, thereby improving the practicability of the device.

[0023] like Figure 1-4 As shown, a slider 16 is fixedly connected to the outer side of the storage plate 15, and a slide groove 17 is symmetrically opened on the inner side of the two fixed blocks 14, and the slider 16 slides in the slide groove 17. A return spring A18 is fixedly connected to one end of the slide groove 17, and the return spring A18 is against the slider 16. When storing and retrieving medical test tubes, the storage plate 15 needs to be taken out, and the purpose of quick retrieval can be achieved through the action of the return spring A18.

[0024] like Figure 1-4 As shown, two fixed blocks 14 are symmetrically provided with installation grooves near the outer edge, and the inner wall of the installation groove is fixedly connected with a reset spring B19, one end of the reset spring B19 is fixedly connected with a grinding block 20, and the grinding block 20 slides in the installation groove, and the grinding block 20 limits the storage plate 15. When taking it, the grinding block 20 is pushed to both sides and the reset spring B19 is compressed to release the limit on the storage plate 15. When storing, after the storage plate 15 is pushed forward, the reset spring B19 quickly drives the grinding block 20 to reset and limit the storage plate 15.

[0025] like Figure 1-4As shown, the four corners of the bottom of the main body 1 are provided with a Formosa wheel 2, and the lower surface of the installation cavity 3 is fixedly connected with a storage tank 7, a vacuum pump 8 and a steam generator 9 from left to right in sequence. The input end of the vacuum pump 8 is fixedly connected to the storage tank 7 through a connecting pipe A, and the output end of the vacuum pump 8 is fixedly connected to the steam generator 9 through a connecting pipe B. The upper surface of the steam generator 9 is fixedly connected to the conduit 12 through an air outlet pipe 10, and the upper surface of the conduit 12 is fixedly connected with a vacuum steam pipe 13, and the vacuum steam pipe 13 is designed at 30 degrees. The end of the air outlet pipe 10 close to the conduit 12 is fixedly connected with a pressure sensor 11, and the pressure sensor 11 detects the steam pressure of the steam generator 9 in real time, thereby improving the safety of the device. At the same time, the vacuum steam pipe 13 is designed at 30 degrees and is in an arc shape in conjunction with the sterilization chamber 4, so that the low-temperature formaldehyde steam can form a reflux in the sterilization chamber 4, and the sterilization effect is better.

[0026] Working principle:

[0027] When in use, first open the upper cabinet door 6, place the medical test tube with the mouth facing upward in the placement hole 27, and the return springs C25 on both sides contract to drive the displacement plate 26 to clamp and fix the medical test tube. Since the sterilization chamber 4 is designed in an arc shape, the low-temperature formaldehyde steam enters the sterilization chamber 4 to form a backflow, and the driving device drives the mounting frame 22 to rotate through the movable rod 21. The input end of the vacuum pump 8 transports the formaldehyde aqueous solution in the storage tank 7 to the steam generator 9 through the connecting pipe A through the connecting pipe B, and the formaldehyde aqueous solution is converted into low-temperature formaldehyde steam through the steam generator 9. The low-temperature formaldehyde steam passes through the exhaust pipe 10 and the conduit 12, and is discharged into the sterilization chamber 4 at 30 degrees through the vacuum steam pipe 13, so that the angle of the medical test tube is adjusted in real time according to the direction of the low-temperature formaldehyde steam, so that the mouth of the medical test tube is always opposite to the steam direction, so that the low-temperature formaldehyde steam quickly enters the end of the inner wall of the medical test tube for sterilization;

[0028] When storing or accessing medical test tubes, the grinding blocks 20 on both sides are pushed outward so that the grinding blocks 20 compress the return springs B19, so that the grinding blocks 20 do not abut against the storage plate 15. The return springs A18 are no longer subjected to force to rebound and push the slider 16 to slide in the slide groove 17. The slider 16 drives the storage plate 15 to move outward, making it more convenient to store or access medical test tubes.
