Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam sterilizer technology, specifically a vertical pressure steam sterilizer. Background Technology
[0002] A vertical pressure steam sterilizer is a device that uses high-temperature saturated steam to sterilize items. It is widely used in many fields such as medical treatment, scientific research, and food processing. It kills microorganisms based on the high temperature and high pressure of steam. Water is heated into steam in the sterilizer. As steam is continuously generated, the pressure inside the container gradually increases. Under normal circumstances, the steam temperature will increase with the increase of pressure. Under high temperature and high pressure, the proteins, nucleic acids and other biological macromolecules of microorganisms will denature, thereby causing the microorganisms to die and achieving the purpose of sterilization.
[0003] However, existing technologies still have the following problems:
[0004] First, if the steam sterilizer is not sealed well, humid air from the outside will continuously enter the container, making it impossible to maintain a stable high-temperature environment inside. As hot air is constantly lost, the container needs to be constantly heated to compensate for the heat loss. Poor sealing can cause a series of safety hazards that may be caused by steam leakage, making it difficult to ensure that a relatively stable sealed environment can be formed inside the container. Poor sealing can also lead to a decline in product quality.
[0005] Secondly, sterilizers need to adapt to different working scenarios and needs. When faced with different amounts of condensate accumulation, it is inconvenient to flexibly control and adjust the drainage speed according to actual needs, resulting in poor flexibility and practicality.
[0006] To address the aforementioned problems, the inventors proposed a vertical pressure steam sterilizer. Utility Model Content
[0007] To address the problems of inconvenience in effectively enhancing the sealing effect of containers and inconvenience in flexibly controlling and adjusting the drainage speed according to actual needs, the purpose of this utility model is to provide a vertical pressure steam sterilizer.
[0008] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a vertical pressure steam sterilizer, including a tank body, two fixing rings fixedly sleeved on the outer surface of the tank body, multiple legs arranged in a ring array fixedly sleeved on the outer surface of the fixing rings, an adjustment device provided at the lower end of the tank body, a sealing device snapped onto the upper end of the tank body, the sealing device including a tank lid, a handle symmetrically fixedly connected to the top surface of the tank lid, multiple fixing blocks arranged in a ring array fixedly connected to the upper end of the tank body, a first rotating shaft rotatably connected between the fixing blocks, a hollow sleeve movably sleeved on the outer surface of the first rotating shaft, a rotating rod rotatably connected to the upper end of the hollow sleeve, multiple slots arranged in a ring array opened on the outer surface of the tank lid, the outer surface of the rotating rod engaging with the slots, rotating the rotating rod to engage with the slots, thus fixing the tank lid, a sealing plate fixedly connected to the bottom end of the tank lid, the outer surface of the sealing plate fitting against the inner wall of the tank body, a sealing groove opened on the top surface of the tank body, and a sealing strip for use with the sealing groove fixedly connected to the bottom end of the tank lid.
[0009] Preferably, the regulating device includes a drain pipe, the top end of which is connected to the tank body. A protective shell is fixedly connected to the outer surface of the drain pipe. A second rotating shaft is movably inserted through the lower end of the protective shell. The top end of the second rotating shaft is rotatably connected to the upper inner wall of the protective shell. A worm gear is fixedly sleeved on the outer surface of the second rotating shaft. A worm is meshed with the outer surface of the worm gear. The worm gear and worm are located inside the protective shell. A knob is movably inserted through one side of the protective shell. The end of the knob extends into the protective shell and is fixedly connected to the worm. The bottom end of the second rotating shaft extends into the drain pipe and is fixedly connected to a ball valve. Rotating the knob causes the worm to rotate. Due to the meshing relationship between the worm and the worm gear, the worm gear drives the second rotating shaft to rotate, thereby causing the ball valve, whose bottom end is located inside the drain pipe and whose outer surface is in contact with the inner wall of the drain pipe, to rotate. The ball valve is located inside the drain pipe, and its outer surface is in contact with the inner wall of the drain pipe.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model can fix the can lid in place by placing it at a suitable position on the upper part of the can body when closing the can lid, and then rotating the rotating rod to make it engage with the slot, thereby making the can lid fit tightly against the can body and thus effectively enhancing the sealing effect of the can body.
[0012] 2. This utility model can drive the worm gear to rotate by turning the knob, which will cause the worm wheel to drive the second shaft to rotate, thereby causing the ball valve, whose bottom end is located inside the drain pipe and whose outer surface is in contact with the inner wall of the drain pipe, to rotate, changing the opening angle of the ball valve, thereby achieving the purpose of effectively controlling the amount of drain flow.

An adjustment device 2 is provided at the lower end of the tank body 1. A sealing device 3 is snapped onto the upper end of the tank body 1. The sealing device 3 includes a tank cover 30. A handle 31 is symmetrically fixedly connected to the top surface of the tank cover 30, which facilitates opening and closing. Multiple fixing blocks 32 arranged in a ring array are fixedly connected to the upper end of the tank body 1. A first rotating shaft 33 is rotatably connected between the fixing blocks 32. A hollow sleeve 34 is movably sleeved on the outer surface of the first rotating shaft 33. A rotating rod 35 is rotatably connected to the upper end of the hollow sleeve 34. Multiple slots 36 arranged in a ring array are opened on the outer surface of the tank cover 30. The outer surface of the rotating rod 35 is snapped into the slots 36.
[0021] A sealing plate 37 is fixedly connected to the bottom end of the can lid 30. The outer surface of the sealing plate 37 is in contact with the inner wall of the can body 1. When the can lid 30 is closed, the sealing plate 37 first contacts the inner wall of the can body 1 to play a preliminary sealing and blocking role. A sealing groove 38 is opened on the top surface of the can body 1. A sealing strip 39 that is used in conjunction with the sealing groove 38 is fixedly connected to the bottom end of the can lid 30. The sealing strip 39 is embedded in the sealing groove 38 to further enhance the sealing effect and prevent steam from leaking from the joint between the can lid 30 and the can body 1. When it is necessary to close the can lid 30, after placing the can lid 30 in a suitable position on the upper end of the can body 1, the rotating rod 35 is rotated to make it snap into the slot 36, which can fix the can lid 30 and make it fit tightly against the can body 1, thereby effectively enhancing the sealing effect of the can body 1.
[0022] The regulating device 2 includes a drain pipe 21, the top end of which is connected to the tank 1. A protective shell 22 is fixedly connected to the outer surface of the drain pipe 21. A second rotating shaft 23 is movably passed through the lower end of the protective shell 22. The top end of the second rotating shaft 23 is rotatably connected to the upper inner wall of the protective shell 22. When the knob 26 is rotated, the knob 26 drives the worm gear 25 to rotate. Due to the meshing relationship between the worm gear 25 and the worm wheel 24, the worm wheel 24 will drive the second rotating shaft 23 to rotate.
[0023] A worm gear 24 is fixedly sleeved on the outer surface of the second rotating shaft 23. A worm 25 is meshed with the outer surface of the worm gear 24. The worm gear 24 and the worm 25 are located inside the protective shell 22. A knob 26 is movably inserted through one side of the protective shell 22. The end of the knob 26 extends into the protective shell 22 and is fixedly connected to the worm 25. The bottom end of the second rotating shaft 23 extends into the drain pipe 21 and is fixedly connected to a ball valve 27. The ball valve 27, located inside the drain pipe 21 and with its outer surface in contact with the inner wall of the drain pipe 21, rotates. The ball valve 27, located inside the drain pipe 21 and with its outer surface in contact with the inner wall of the drain pipe 21, can effectively control the drain flow rate.
[0024] Working principle: When the can lid 30 is closed, the sealing plate 37 first contacts the inner wall of the can body 1 to play a preliminary sealing and blocking role. The sealing strip 39 is embedded in the sealing groove 38 to further enhance the sealing effect and prevent steam from leaking from the joint between the can lid 30 and the can body 1. The top surface of the can lid 30 is symmetrically and fixedly connected with a handle 31 for easy operation to open and close. When it is necessary to close the can lid 30, after placing the can lid 30 in a suitable position on the upper end of the can body 1, the rotating rod 35 is rotated to make it snap into the slot 36, which can fix the can lid 30 and make it fit tightly against the can body 1, thereby achieving the purpose of effectively strengthening the sealing effect of the can body 1.
[0025] When it is necessary to adjust the flow rate of the drain, turn knob 26. Knob 26 drives worm 25 to rotate. Due to the meshing relationship between worm 25 and worm wheel 24, worm wheel 24 will drive second shaft 23 to rotate, which in turn causes ball valve 27, whose bottom end is located inside drain pipe 21 and whose outer surface is in contact with the inner wall of drain pipe 21, to rotate. By changing the opening angle of ball valve 27, the purpose of effectively controlling the flow rate of the drain can be achieved.
[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
