Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure sterilizing pots, in particular to a high-pressure sterilizing pot. Background Art

[0002] Autoclave, also known as high-pressure steam sterilizer, can be divided into portable autoclave and vertical autoclave. It is a device that uses electric heating wire to heat water to generate steam and maintain a certain pressure. It mainly consists of a sealed barrel, pressure gauge, exhaust valve, safety valve, electric heating wire, etc. Autoclave is a device used for disinfection and sterilization. It uses high-pressure steam to kill bacteria, viruses, spores and other microorganisms. This equipment is very important in the medical, laboratory, food processing and pharmaceutical industries.

[0003] The autoclave is usually heated to generate steam inside the pot. When the pressure is reached, the exhaust valve is opened to discharge the cold air. After the discharge is completed, the exhaust valve is closed and heating is continued to maintain the required steam pressure for a certain period of time. The sterilizer is then powered off or the fire is turned off, and the sterilizer is allowed to cool naturally before the exhaust valve is slowly opened to discharge the remaining gas. Only then can the lid be opened to take out the items. After sterilization, impurities and disinfectants will remain in the autoclave. The pot should be immediately scrubbed with clean water to remove the remaining impurities and disinfectants. Cleaning the autoclave is essential to ensure the sterilization effect and the long-term stable operation of the equipment. However, there are dead corners at the bottom of the autoclave, which reduces the efficiency and effectiveness of device cleaning. Utility Model Content

[0011] As a further improvement of the above technical solution: the bottom of the cooling zone is connected to the water tank through a pipeline.

[0012] The beneficial effect of this improvement is that the circulating water pump pumps the coolant to the inside of the cooling zone through the pipeline, and then returns to the inside of the water storage tank through the pipeline to form a cooling circulation water circuit. This method can effectively and quickly cool the device.

[0013] In order to facilitate the cleaning of the sterilization liner with a brush plate:

[0014] As a further improvement of the above technical solution: the cross-section of the brush plate is U-shaped, and the brush plate fits tightly against the sterilization liner.

A driving motor 5 is installed at the bottom of the sterilizing pot body 1, and a brush plate 51 is rotatably connected to the top of the driving motor 5. A temperature insulation layer 52 is installed near the driving motor 5 inside the sterilizing pot body 1. During the drainage process, the driving motor 5 drives the brush plate 51 to rotate and scrub the bottom of the sterilization liner 13 to prevent impurities from adhering to the bottom of the sterilization liner 13, thereby ensuring the efficiency and effect of cleaning the inside of the sterilization liner 13. An exhaust valve is installed on the exhaust pipe 3, and one end of the exhaust pipe 3 is connected to the sterilization liner 13. When the device is in use, opening the exhaust valve can facilitate the exhaust of air from the inside of the sterilizing pot body 1. The bottom of the cooling zone 4 is connected to the water tank 42 through a pipeline. The circulating water pump 41 pumps the coolant to the inside of the cooling zone 4 through the pipeline, and then returns to the inside of the water tank 42 through the pipeline to form a cooling circulation water circuit. This method can effectively and quickly cool the device. The cross-section of the brush plate 51 adopts a U-shaped setting, and the brush plate 51 and the sterilization liner 13 are tightly fitted. The U-shaped setting can make the brush plate 51 rotate one circle to clean the bottom of the sterilization liner 13 twice, ensuring the cleaning efficiency and effect. The tightly fitted brush plate 51 can ensure that the brush plate 51 cleans the sterilization liner 13 more reliably and comprehensively. The drive motor 5 and the brush plate 51 are plug-in The plug-in connection can make the brush plate 51 firmly and quickly installed above the driving motor 5. The inner side circumference of the sterilizing liner 13 is provided with a convex block, which can support the storage basket 14, so that the user can take the storage basket 14 out of the sterilizing pot body 1. A drain valve is installed above the drainage pipe 31. Opening the drain valve can facilitate wastewater to enter the wastewater tank 32 through the drainage pipe 31. The top of the sterilizing pot body 1 is equipped with a rotating shaft 2, and the upper half of the rotating shaft 2 is equipped with a rotating frame 21. The middle part of the rotating frame 21 is equipped with a hand-cranked threaded rod 22, and the lower part of the hand-cranked threaded rod 22 is rotatably connected to the pressure cooker cover 23, and the pressure cooker cover 23 is installed with a pressure gauge 24.The rotating frame 21 rotates along the rotating shaft 2 so that the pressure cooker cover 23 reaches the top of the sterilizing pot body 1.

[0036] The working principle of the utility model is as follows: when using the device, water is poured into the sterilization liner 13, and after the water is poured, the storage basket 14 and the articles are placed inside the sterilization liner 13. At this time, the rotating frame 21 rotates along the rotating shaft 2 to make the pressure cooker cover 23 reach the top of the sterilization pot body 1. At this time, the hand-cranked threaded rod 22 is rotated to drive the pressure cooker cover 23 to seal the top of the sterilization pot body 1. After the sealing is completed, the electric heating wire 11 heats the sterilization liner 13 to sterilize the articles. After the sterilization is completed, the circulating water pump 41 pumps the coolant in the water tank 42 to the inside of the cooling zone 4, and the cooling zone 4 cools down the sterilization liner 13. The coolant is heated After being heated, it flows into the interior of the water storage tank 42. The reciprocating cycle can accelerate the reduction of the temperature in the device. After the cooling is completed, the exhaust valve is opened to discharge the high-pressure gas through the exhaust pipe 3. Then, the pressure cooker cover 23 is removed from the top of the sterilizing pot body 1, and the items can be quickly taken out from the interior of the sterilizing liner 13 through the storage basket 14. At this time, the drain valve is opened, and the waste water at the bottom of the sterilizing liner 13 is discharged into the interior of the waste water tank 32 through the drain pipe 31. During the drainage process, the driving motor 5 drives the brush plate 51 to rotate to scrub the bottom of the sterilizing liner 13 to prevent impurities from adhering to the bottom of the sterilizing liner 13, thereby ensuring the efficiency and effect of cleaning the interior of the sterilizing liner 13.
