[0003] The existing pressure steam sterilization device includes a kettle body, a sealing cover and a plurality of screws arranged on the sealing cover. When the staff puts the items to be sterilized into the kettle body and places the sealing cover on the top of the kettle body, the staff needs to rotate a plurality of bolts respectively to connect the sealing cover with the kettle body. Only after ensuring that the kettle body is sealed can the items be sterilized. This process is time-consuming and labor-intensive, and the operation process is cumbersome and very inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a vertical pressure steam sterilization device, which solves the problem in the prior art that after the staff puts the articles to be sterilized into the kettle body and places the sealing cover on the top of the kettle body, the staff needs to rotate several bolts respectively to connect the sealing cover with the kettle body, and can continue to sterilize the articles only after ensuring the sealing of the kettle body, and this process is time-consuming, labor-intensive, and the operation process is cumbersome and very inconvenient.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a vertical pressure steam sterilization device comprises a kettle body and a sealing cover, an annular block is integrally formed at the bottom of the sealing cover, an annular groove for the annular block to be inserted is provided at the top of the kettle body, air bags are fixed on the inner and outer walls of the annular block, an inflation hole is also provided on the sealing cover, one end of the inflation hole extends to the inside of the annular block and is respectively connected with two air bags through an air pipe, a sealing member is also fixed on the top of the inflation hole, and the kettle body and the sealing cover are connected by a fixing mechanism.

[0006] Wherein, limiting grooves are arranged on both sides of the inner wall of the annular groove.

[0007] By adopting the above technical scheme, when the articles are actually sterilized by the vertical pressure steam sterilization device, first, the staff puts the articles into the kettle body, then takes the sealing cover, aligns the annular block with the annular groove and snaps it in, then connects the air pump to the inflation hole, and then uses the air pump to inflate the inflation hole. The gas expands the two airbags through the air pipe so that the airbags are tightly pressed against the inner wall of the limiting groove. On the one hand, the contact area between the airbag and the limiting groove is increased, and the friction and sealing are improved. On the other hand, the opening of the arc-shaped limiting groove can effectively limit the up and down movement of the airbag, so that not only the sealing cover can be stably installed on the top of the kettle body, but also the gas inside the kettle body is not easy to leak, which can effectively ensure the high-pressure environment in the kettle body, so that the connection and sealing operation of the sealing cover and the kettle body are convenient, saving time and effort.

[0008] The utility model is further configured as follows: the fixing mechanism includes two connecting plates rotatably connected to both sides of the kettle body, a fixing block is arranged at one end of the connecting plate, fixing grooves for the fixing blocks to be snapped into are opened on both sides of the sealing cover, a buckle is arranged at the bottom of the fixing block, and a slot for the buckle to be snapped into is arranged on the inner wall of the fixing groove.

[0009] The connecting plate is rotatably connected to the kettle body through a rotating member, and the rotating member includes a fixing seat integrally formed on the outer wall of the kettle body, and a rotating shaft is rotatably connected inside the fixing seat, and the connecting plate is fixed on the rotating shaft.

[0010] By adopting the above technical scheme, when fastening the sealing cover through the fixing mechanism, the staff only needs to rotate the two connecting plates towards the fixing groove at the same time. The rotation of the connecting plates drives the rotating shaft to rotate in the fixing seat while driving the fixing block to rotate towards the fixing groove until the fixing block is inserted into the fixing groove. At the same time, the buckle is inserted into the inside of the slot. The sealing cover is limited by the fixing block, so that the sealing cover is not easy to rotate or to separate upward from the kettle body. The fixing block is limited after the buckle is inserted into the slot, so that the fixing block is not easy to rotate, and thus not easy to separate from the fixing groove, so that the fixing mechanism can connect the sealing cover to the kettle body more firmly. When the pressure in the kettle body increases, the sealing cover is not easy to separate from the kettle body, thereby successfully completing the sterilization process.

[0011] The utility model is further configured as follows: both fixing blocks are connected with pressure blocks in a sliding manner vertical to the surface of the fixing blocks, the inner wall of the fixing groove is provided with a slot for the pressure blocks to be inserted into, a convex block is fixed at the bottom of the pressure block, and the inner wall of the bottom of the fixing groove is provided with a groove for the convex block to be inserted into.

[0012] By adopting the above technical scheme, when the buckle is inserted into the slot, the pressure block is just aligned with the slot. At this time, the staff can insert the two pressure blocks into the slot respectively, and the protrusion can be inserted into the groove. After the pressure block is inserted into the slot, the fixed block is limited, making it more difficult for the fixed block to fall out of the fixed slot. After the protrusion is engaged with the groove, the pressure block is limited, making it difficult for the pressure block to fall out of the slot, thereby making the limiting effect of the fixed block on the sealing cover more stable, so that the sealing cover can be more firmly fixed on the kettle body, and the operation process is simple and very convenient.

[0013] The utility model is further configured as follows: a clamping ring is arranged on the top of the pressing block.

[0014] By adopting the above technical solution, the setting of the clamping ring enables the staff to slide the pressing block more conveniently, and the operation is more convenient.

[0015] The utility model is further configured as follows: annular handles are integrally formed on both sides of the sealing cover.

[0016] By adopting the above technical solution, when the staff needs to take the sealing cover, they can take the sealing cover more conveniently by simply holding the annular handle.

[0017] The utility model is further configured as follows: a plurality of casters are fixed on the bottom of the kettle body.

[0018] By adopting the above technical solution, when the staff needs to move the vertical pressure steam sterilization device, they only need to push the kettle body to move the device, and the setting of the casters makes the movement of the device more convenient and labor-saving.

[0019] The beneficial effect of the utility model is that when the articles are actually sterilized by the vertical pressure steam sterilization device, the sealing cover is taken, the annular block is aligned with the annular groove and inserted, and then the air pump is connected to the inflation hole, and then the inflation hole is inflated by the air pump to expand the two air bags so that the air bags are tightly pressed against the inner wall of the limiting groove, which can effectively ensure the high-pressure environment in the kettle body, thereby making the connection and sealing operation of the sealing cover and the kettle body convenient, saving time and effort.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0027] Figure 2 , Figure 3 and Figure 4 As shown, a vertical pressure steam sterilization device includes a kettle body 1 and a sealing cover 2. An annular block 12 is integrally formed at the bottom of the sealing cover 2. An annular groove 15 for the annular block 12 to be inserted is provided on the top of the kettle body 1. Air bags 11 are fixed on the inner and outer walls of the annular block 12. An inflation hole 18 is also provided on the sealing cover 2. One end of the inflation hole 18 extends to the inside of the annular block 12 and is connected to the two air bags 11 respectively through a plurality of air pipes 17. A sealing member is also fixed on the top of the inflation hole 18. The kettle body 1 and the sealing cover 2 are connected by a fixing mechanism.

[0028] Wherein, limiting grooves 16 are provided on both sides of the inner wall of the annular groove 15 .

[0029] When the articles are actually sterilized by the vertical pressure steam sterilization device, first, the staff puts the articles into the kettle body 1, then takes the sealing cover 2, aligns the annular block 12 with the annular groove 15 and snaps it in, then connects the air pump to the inflation hole 18, and then uses the air pump to inflate the inflation hole 18. The gas expands the two air bags 11 through the air pipe 17 so that the air bags 11 are tightly pressed against the inner wall of the limiting groove 16. On the one hand, the contact area between the air bags 11 and the limiting groove 16 is increased, and the friction and sealing are improved. On the other hand, the opening of the arc-shaped limiting groove 16 can effectively limit the up and down movement of the air bags 11, so that not only the sealing cover 2 can be stably installed on the top of the kettle body 1, but also the gas inside the kettle body 1 is not easy to leak, which can effectively ensure the high-pressure environment in the kettle body 1, so that the connection and sealing operation of the sealing cover 2 and the kettle body 1 are convenient, saving time and effort.

[0030] The sealing member is a rubber plug 5, so as to facilitate the sealing of the inflation hole 18. In addition, the fixing mechanism can make the connection between the kettle body 1 and the sealing cover 2 more secure.

[0031] like Figure 4 and Figure 5 As shown, the fixing mechanism includes two connecting plates 9 rotatably connected to both sides of the kettle body 1, a fixing block 6 is arranged at one end of the connecting plate 9, fixing grooves 13 for the fixing block 6 to be snapped into are provided on both sides of the sealing cover 2, a buckle 22 is provided at the bottom of the fixing block 6, and a slot 19 for the buckle 22 to be snapped into is provided on the inner wall of the fixing groove 13.

[0032] The connecting plate 9 is rotatably connected to the kettle body 1 via a rotating member. The rotating member includes a fixing seat 10 integrally formed on the outer wall of the kettle body 1 . A rotating shaft 21 is rotatably connected inside the fixing seat 10 , and the connecting plate 9 is fixed on the rotating shaft 21 .

[0033] When fastening the sealing cover 2 through the fixing mechanism, the staff only needs to rotate the two connecting plates 9 towards the fixing groove 13 at the same time. The rotation of the connecting plate 9 drives the rotating shaft 21 to rotate in the fixing seat 10 while driving the fixing block 6 to rotate towards the fixing groove 13 until the fixing block 6 is stuck in the fixing groove 13. At the same time, the buckle 22 is stuck in the inside of the slot 19. The sealing cover 2 is limited by the fixing block 6, so that the sealing cover 2 is not easy to rotate or to separate upward from the kettle body 1. The fixing block 6 is limited after the buckle 22 is stuck in the slot 19, so that the fixing block 6 is not easy to rotate, and thus not easy to separate from the fixing groove 13, so that the fixing mechanism can connect the sealing cover 2 to the kettle body 1 more firmly. When the pressure in the kettle body 1 increases, the sealing cover 2 is not easy to separate from the kettle body 1, thereby successfully completing the sterilization process.

[0034] like Figure 4 As shown, both fixing blocks 6 are slidably connected with a pressing block 7 along the vertical direction of the surface of the fixing block 6, a slot 14 for the pressing block 7 to be inserted is provided on the inner wall of the fixing groove 13, a protrusion 23 is fixed at the bottom of the pressing block 7, and a groove 20 for the protrusion 23 to be inserted is provided on the inner wall of the bottom of the fixing groove 13.

[0035] Wherein, a clamping ring 8 is arranged on the top of the pressing block 7 .

[0036] When the buckle 22 is inserted into the slot 19, the pressing block 7 is aligned with the slot 14. At this time, the staff can insert the two pressing blocks 7 into the slot 14 respectively, and the protrusion 23 can be inserted into the groove 20. After the pressing block 7 is inserted into the slot 14, the fixing block 6 is limited, so that the fixing block 6 is more difficult to be separated from the fixing slot 13. After the protrusion 23 is engaged with the groove 20, the pressing block 7 is limited, so that the pressing block 7 is not easy to be separated from the slot 14, so that the limiting effect of the fixing block 6 on the sealing cover 2 is more stable, thereby making

[0037] The sealing cover 2 can be more firmly fixed on the kettle body 1, and the operation process is simple and convenient.

[0038] In addition, the provision of the clamping ring 8 enables the staff to slide the pressing block 7 more conveniently, making the operation more convenient.

[0039] like Figure 1 As shown, annular handles 4 are integrally formed on both sides of the sealing cover 2 .

[0040] When the staff needs to take the sealing cover 2 , they can take the sealing cover 2 more conveniently by simply holding the annular handle 4 .

[0041] like Figure 1 As shown, a plurality of casters 3 are fixed to the bottom of the kettle body 1.

[0042] When the staff needs to move the vertical pressure steam sterilization device, they only need to push the kettle body 1 to move the device, and the provision of the casters 3 makes the movement of the device more convenient and labor-saving.

[0043] Working principle:

[0044] When the articles are actually sterilized by the vertical pressure steam sterilization device, first, the staff puts the articles into the kettle body 1, then takes the sealing cover 2, aligns the annular block 12 with the annular groove 15 and snaps it in, then connects the air pump to the inflation hole 18, and then uses the air pump to inflate the inflation hole 18. The gas expands the two air bags 11 through the air pipe 17 so that the air bags 11 are tightly pressed against the inner wall of the limiting groove 16. Then, the staff only needs to rotate the two connecting plates 9 towards the direction of the fixing groove 13 at the same time. The rotation of the connecting plate 9 drives the rotating shaft 21 to rotate in the fixing seat 10 while driving the fixing block 6 to rotate towards the direction of the fixing groove 13 until the fixing block 6 is snapped into the fixing groove 13. At the same time, the buckle 22 is snapped into the inside of the card slot 19. At this time, the staff can snap the protrusion 23 into the inside of the groove 20 by inserting the two pressing blocks 7 into the slot 14 respectively, so as to firmly fix the sealing cover 2 on the kettle body 1, and the operation process is simple and very convenient.
