[0002] High-pressure steam sterilizer is a device that uses saturated pressure steam to quickly and reliably disinfect and sterilize items. It is suitable for medical and health care, scientific research, agriculture and other units. High-pressure steam sterilizers are classified according to style and size into portable high-pressure steam sterilizers, vertical pressure steam sterilizers, horizontal high-pressure steam sterilizers, etc. High-pressure steam sterilizers can be used to disinfect and sterilize medical devices, dressings, glassware, solution culture media, etc. It is also suitable for use as steaming equipment in plateau areas and for enterprises and institutions to produce high-quality drinking water. It can also be used as a high-temperature steam source equipment.

[0003] When using a traditional high-pressure steam sterilizer, due to the compact internal space of the steam sterilizer, when the instrument needs to be taken out of the device, the temperature of the instrument surface and the inner wall of the sterilizer is high, which can easily scald the user during the removal process. In addition, since the steam outlet pipe is fixedly installed, the direction of the steam entering the sterilization chamber remains unchanged, and the steam maintains one outlet direction for a long time, making it difficult to ensure the overall uniformity of the steam distribution in the sterilization chamber, resulting in incomplete and uneven sterilization in some locations in the sterilization chamber. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned situation that the surface of the instrument after sterilization and the inner wall temperature of the sterilization device are high, which easily scalds the user during the transportation process; in addition, the steam maintains one exhaust direction for a long time, and it is difficult to ensure the overall distribution uniformity of the steam in the sterilization chamber, resulting in incomplete and uneven sterilization in some positions in the sterilization chamber. A high-pressure steam sterilization device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-pressure steam sterilization device, comprising a sterilization box, the interior of the sterilization box is a hollow structure, grooves are provided at the upper and lower ends of the inner wall of the sterilization box, a cavity is provided inside the sterilization box, a sealing door is movably installed on the surface of the sterilization box, an air inlet pipe is fixedly installed on one side of the outer wall of the sterilization box, a pressure relief valve is fixedly installed on the top of the sterilization box, brackets are fixedly connected on both sides of the inner wall of the sterilization box, a driving motor is movably installed on the top of the sterilization box, four bearing plates are provided inside the sterilization box, a push plate is movably installed inside the sterilization box, the upper and lower ends of the push plate are fixedly connected to fixed plates, a stabilizing seat is fixedly installed on the surface of the push plate, and a guide plate is fixedly installed inside the cavity.

[0007] Preferably, a screw is movably installed inside the two grooves, a bevel gear 1 is fixedly connected to one side of the screw, and the inner wall of the fixing plate is threadedly connected to the surface of the screw.

[0008] Preferably, the output shaft of the driving motor is connected to a connecting rod, and two bevel gears are fixedly mounted on the surface of the connecting rod, and the side surfaces of the bevel gears are meshed with the side surfaces of the bevel gears.

[0009] Preferably, the interior of the guide plate is a hollow structure, and one side of the air inlet pipe is located inside the guide plate.

[0010] Preferably, four connection blocks are fixedly connected to one side of the outer wall of the guide plate, one end of the connection block is fixedly installed on one side of the inner wall of the sterilization box, and the connection block is located on the side of the supporting plate.

[0011] Preferably, one side of the four connecting blocks is provided with an air outlet, and the sizes of the four air outlet holes decrease from bottom to top.

[0025] In this embodiment, the items to be sterilized are placed on the top of the carrier plate 3, and then the sealing door 11 is closed, and high-pressure steam is added to the air inlet pipe 12 to steam sterilize the items inside the sterilization box 1. When the pressure inside the sterilization box 1 is too high, the pressure relief valve 13 is opened under pressure to relieve the pressure inside the sterilization box 1. When the sterilization operation is completed, the sealing door 11 is opened, and the drive motor 2 is started to drive the connecting rod 21 and the bevel gear 22 to rotate. The bevel gear 22 engages with the bevel gear 1 16 to rotate the screw 15 together, and the fixed plate 41 simultaneously drives the push plate 4 to move, pushing the carrier plate 3 outward. At this time, the items on the top of the carrier plate 3 are located outside the sterilization box 1 and can be removed after cooling down slightly. There is no need for personnel to take out the items inside the sterilization box 1 to avoid scalding.

[0026] Example 2

[0027] like Figure 1-Figure 5 As shown, a guide plate 5 is fixedly installed inside the cavity 102, and the interior of the guide plate 5 is a hollow structure. One side of the air inlet pipe 12 is located inside the guide plate 5, and one side of the outer wall of the guide plate 5 is fixedly connected with four connecting blocks 51. One end of the connecting block 51 is fixedly installed on one side of the inner wall of the sterilization box 1. The connecting block 51 is located on the side of the supporting plate 3, and one side of the four connecting blocks 51 is provided with an air outlet hole 511, and the size of the four air outlet holes 511 decreases successively from bottom to top.

[0028] In this embodiment, steam enters the guide plate 5 from the air inlet pipe 12 and is respectively ejected from four connecting blocks 51. The connecting blocks 51 are located on the side of the supporting plate 3, so that the steam is ejected from the air outlet 511 to the surface of the object. Since the sizes of the air outlet holes 511 of the four connecting blocks 51 decrease from bottom to top, the amount of steam ejected from the four connecting blocks 51 decreases successively. The objects on the bottom layer are subjected to more steam sterilization, and the steam on the bottom layer will pass through the through hole 301 and rise to the top of the sterilization box 1. The sides of the objects on the top layer will contact the steam discharged from the air outlet 511, and the bottom will contact the steam rising from the bottom, so that the steam distribution inside the sterilization box 1 is more even.

[0029] The working principle of this embodiment is as follows: the articles are placed on the top of the carrier plate 3 at different positions respectively, and then the sealing door 11 is closed, and high-pressure steam is added to the air inlet pipe 12. The steam enters the guide plate 5 from the air inlet pipe 12 and is ejected from the four connecting blocks 51 respectively. The steam is ejected from the air outlet 511 to the surface of the articles. The articles on the bottom layer are sterilized with more steam, and the articles on the top layer are simultaneously exposed to the steam discharged from the air outlet 511 and the steam rising from the bottom, so that the articles are heated more evenly. Then the sealing door 11 is opened, and the driving motor 2 is started to drive the connecting rod 21 and the bevel gear 2 22 to rotate. The bevel gear 2 22 drives the screw 15 to rotate together by meshing with the bevel gear 1 16. The push plate 4 pushes the carrier plate 3 outward and waits for it to cool down slightly before removing it.
