Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 2 , a water bath sterilizer, including a sterilizer body 1 and a water storage tank 2 installed on the top outside the sterilizer.

The plurality of loading frames 3 are stacked on top of each other in the sterilizer body 1 from bottom to top through the limit snap rings 32. The setting of the limit snap rings 32 can limit the upper and lower adjacent loading frames 3, so that multiple layers of loading frames 3 are stacked on top of each other inside the sterilizer body 1, and then it can simultaneously perform the function of water bath sterilization on a large number of bagged items;

[0044] A cover plate 33 is provided on the loading frame 3 at the uppermost layer of the inner cavity of the sterilizer body 1, and a plurality of through holes are provided on the cover plate 33;

[0045] Furthermore, it can play a role in limiting the bagged items at the uppermost loading frame 3, preventing the bagged items from floating out due to the buoyancy of the hot circulating water.

[0046] A support net 4 is provided inside the loading frame 3 and above the filter plate 31. In this embodiment, the support net 4 itself has a relatively light mass. Therefore, when the support net 4 is immersed in the hot circulating water, it has a certain buoyancy, which can drive the bagged items to move upward along the water. And the bagged items are placed on the support net 4. A connecting mechanism 5 for connecting the support net 4 is provided inside the loading frame 3;

[0047] Please refer to Figures 11 to 13 , the connecting mechanism 5 includes a connecting sleeve 51, a connecting rod 52, a connecting block 53 and a support clamping mechanism 54. There are four connecting sleeves 51, and the four connecting sleeves 51 are respectively fixedly installed around the support net 4. The connecting rod 52 slides through the connecting sleeve 51. There are four connecting blocks 53, and the four connecting blocks 53 are respectively located at the four corners of the support net 4, and one end of the two vertically distributed connecting rods 52 is fixedly connected to the connecting block 53;

[0048] There are four support clamping mechanisms 54, and the four support clamping mechanisms 54 are respectively fixedly installed at the four corners of the top of the filter plate 31, and the support clamping mechanism 54 is used to support and limit the connecting block 53.

[0049] The support clamping mechanism 54 includes a support tube 541, a clamping rod 542, a clamping block 543, a pushing block 544, a guide rod 545 and a clamping spring 546. The bottom of the support tube 541 is fixedly installed on the filter plate 31. There are two clamping openings on the support tube 541, and the clamping block 543 slides through the clamping openings. The connecting block 53 is slidably sleeved outside the support tube 541, and the connecting block 53 is located at the bottom of the clamping block 543. In this embodiment, the clamping block 543 is arranged in a wedge shape, so that it is convenient for the connecting block 53 to be sleeved from above the support tube 541 and move down to the bottom of the support tube 541 through the clamping block 543. One end of the two clamping blocks 543 located inside the clamping openings is respectively fixedly connected to the two clamping rods 542. The end of the clamping rod 542 away from the clamping block 543 is located at the top opening 511 of the support tube 541 and is fixedly connected to the pushing block 544;

[0051] There are a plurality of clamping springs 546, and both ends of the plurality of clamping springs 546 are respectively fixedly connected to the sides of the two clamping rods 542 close to each other;

[0052] Specific implementation process: When installing the support net 4, the four connecting blocks 53 are respectively sleeved outside the corresponding support pipes 541. At the same time, the connecting blocks 53 pass through the two clamping blocks 543 of the support pipes 541. Then, the support net 4 is installed in the loading frame 3 through the connecting sleeve 51 and the connecting rod 52. When the support net 4 needs to be disassembled, the two pushing blocks 544 at the support pipes 541 are respectively pressed, so that the two pushing blocks 544 move towards each other. When the pushing blocks 544 move, the clamping blocks 543 are further driven by the clamping rods 542 to move along the clamping ports to the inside of the support pipes 541. At this time, the support net 4 can be pushed upward to realize the rapid disassembly of the support net 4.

[0053] Please refer to Figures 4 to 10 , there are two auxiliary floating mechanisms 6 on the support net 4, and an inflation mechanism 7 is provided at the loading frame 3. The inflation mechanism 7 inflates the auxiliary floating mechanisms 6 through the change of the internal air pressure of the sterilizer body 1, so that the bagged items at the support net 4 float in the loading frame 3, and the bagged items are dispersed from each other during the water bath sterilization.

[0054] The auxiliary floating mechanism 6 includes floating plates 61, floating balls 62, connecting pipes 63 and air guide pipes 64. There are multiple floating plates 61, and the multiple floating plates 61 are distributed in a row on the support net 4. Installation holes are provided at the positions of the support net 4 corresponding to the floating plates 61, and the floating plates 61 penetrate through the installation holes. The connecting pipes 63 penetrate through the floating plates 61. In this embodiment, the connecting pipes 63 are rigid pipes, so that the connecting pipes 63 can play a role in supporting the floating balls 62. At the same time, the air guide pipes 64 are telescopic hoses, so that when the support net 4 moves relative to the inside of the loading frame 3, it can move synchronously with the support net 4 without affecting the movement of the support net 4. The tops of the connecting pipes 63 are communicated with the floating balls 62, and the bottoms of the multiple connecting pipes 63 are communicated with the air guide pipes 64. One end of the air guide pipe 64 is connected to the inflation mechanism 7, a one-way valve is installed on the air guide pipe 64 and close to the inflation mechanism 7, and a valve is provided at the other end of the air guide pipe 64. After each water bath sterilization, the gas can be discharged by opening the valve, and then the next inflation can be carried out.

[0055] The inflation mechanism 7 includes a sealed housing 71, a gas storage member 72, a pushing plate 73, a gas guide cylinder 74 and a propulsion member 75. The sealed housing 71 is fixedly installed outside the loading frame 3. The gas storage member 72 is located inside the sealed housing 71. The pushing plate 73 is slidably connected inside the sealed housing 71, and one side of the pushing plate 73 is in contact with the gas storage member 72. There are two gas guide cylinders 74, and one ends of the two gas guide cylinders 74 are communicated with the sealed housing 71. The propulsion member 75 is located at the gas guide cylinders 74, and the two propulsion members 75 are used to push the pushing plate 73.

[0056] Please refer toFigures 8 to 9 The air storage member 72 includes a high-temperature resistant air storage bag 721. One side of the high-temperature resistant air storage bag 721 is communicated with an air outlet pipe 722. The air outlet pipe 722 penetrates through one side of the loading frame 3. One end of the air outlet pipe 722 located inside the loading frame 3 is communicated with the air guide pipe 64. The pushing plate 73 is used to push the high-temperature resistant air storage bag 721.

[0057] The pushing member 75 includes a pushing rod 751, a buffer spring 752 and a pushing piston 753. One end of the pushing rod 751 is fixedly connected to the pushing plate 73, and the other end of the pushing rod 751 passes through the sealing housing 71 and is fixedly connected to the pushing piston 753. The pushing rod 751 is slidably connected to the sealing housing 71, and the pushing piston 753 is cooperatively connected to the air guide cylinder 74. The buffer spring 752 is sleeved outside the pushing rod 751. One end of the buffer spring 752 is fixedly connected to the outside of the sealing housing 71, and the other end of the buffer spring 752 is fixedly connected to the pushing piston 753.

[0058] A limiting ring 741 is provided on the inner circle of the air guide cylinder 74. The limiting ring 741 is close to the opening 511 of the air guide cylinder 74, and the limiting ring 741 is used to limit the pushing piston 753.

[0059] Specific implementation process: When hot circulating water is introduced into the sterilization tank body, and at the same time the hot circulating water soaks the bagged items in the multi-layer loading frames 3 inside the sterilization tank body, then due to the increase in temperature and pressure inside the sterilization tank, and at the same time as the hot circulating water increases, at this time, the air pressure inside the sealing housing 71 is less than the air pressure inside the sterilization tank body, so the external air pressure causes the pushing piston 753 to move along the air guide cylinder 74. As the pushing piston 753 moves, it synchronously drives the pushing plate 73 to move through the pushing rod 751, and then the pushing plate 73 moves along the inside of the sealing housing 71. When the pushing plate 73 moves along the sealing housing 71, the pushing plate 73 synchronously pushes the high-temperature resistant air storage bag 721. When the air pressure value received by the one-way valve at the air guide pipe 64 reaches the set value, the valve flap at the one-way valve is pushed open, and the air flow enters the connecting pipe 63 through the air guide pipe 64 and enters the floating ball 62 through the connecting pipe 63. At this time, the buoyancy at the floating ball 62 increases, and further the buoyancy of multiple floating balls 62 in two columns on the support net 4 increases simultaneously. Further, the support net 4 is driven by the floating plate 61 to separate from the filter plate 31 at the bottom of the loading frame 3 until the support net 4 floats in the hot circulating water, so that multiple bagged items on the support net 4 float in the hot circulating water, further increasing the contact area between the bagged items and the hot circulating water and ensuring the full sterilization of the bagged items.

[0062] Furthermore, when the connecting sleeve 51 is connected to the connecting rod 52, by bonding the magic male fastener 512 and the magic female fastener 513 at the opening 511 to each other, the connecting sleeve 51 can be stably wound around the outer side of the connecting rod 52, so that the connecting sleeve 51 can play a role in supporting the support net 4. At the same time, the setting of this kind of connecting sleeve 51 can also make the connecting sleeve 51 be quickly detached from the connecting rod 52.

[0063] Embodiment 3
