the utility model provides a portable high pressure steam sterilization pot, includes the sterilization pot body and can dismantle the upper cover of connection, the internal heating device that is provided with of sterilization pot, is provided with on this heating device and puts the thing platform, the upper cover can be dismantled and be connected with plasma generation mechanism, and plasma generation mechanism includes external plasma power, inserts the electrode rod of the sterilization pot body from the upper cover to and set up the apron that is used for sealing connection electrode rod and upper cover in the electrode rod upper end.
And an insulating part is arranged between the electrode rod and the cover plate and between the electrode rod and the upper cover.
The cover plate is provided with an air exhaust opening used for communicating the sterilization pot body, and the air exhaust opening is used for exhausting negative pressure to the sterilization pot body through an external negative pressure air exhaust device.
The upper cover is provided with an air release valve and a safety valve which are communicated with the sterilization pot body, and a pressure gauge for detecting the pressure of the sterilization pot body.
According to the technical scheme, the sterilization is carried out by adopting the steps of firstly carrying out steam sterilization and then carrying out plasma sterilization, and the generated plasma can directly influence the physiological activities and metabolism of bacteria or germ cells and finally cause death, so that the sterilization pot is ensured to be more thoroughly sterilized, and the sterilization pot is convenient and rapid to use, has no residue and no secondary pollution after sterilization and is thoroughly clean.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 10. the device comprises a sterilizing pot body, 20 parts of an upper cover, 21 parts of a sterilizing pot body, an air release valve, 22 parts of a safety valve, 23 parts of a pressure gauge, 30 parts of a heating device, 40 parts of a placing table, 50 parts of a plasma generating mechanism, 51 parts of a plasma power supply, 52 parts of an electrode rod, 53 parts of a cover plate, 54 parts of an insulating part, 55 parts of an air suction opening.
Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in figure 1, the portable high-pressure steam sterilization pot comprises a sterilization pot body 10 and a detachably connected upper cover 20, wherein the upper cover is provided with a deflation valve 21 and a safety valve 22 which are communicated with the sterilization pot body, and a pressure gauge 23 for detecting the pressure of the sterilization pot body. The sterilization pot is internally provided with a heating device 30 which is provided with an object placing table 40 and can adopt a heating wire.
The plasma generating mechanism 50 comprises a plasma power supply 51, an electrode rod 52 and a cover plate 53, the plasma power supply is external, the anode of the plasma power supply is connected with the sterilization pot body 10, the cathode of the plasma power supply is connected with the electrode rod, the electrode rod is inserted from the upper cover when being installed, the lower end of the electrode rod extends into the lower side of the inside of the sterilization pot body, an insulating part 54 is arranged between the electrode rod and the cover plate and between the electrode rod and the upper cover, and the insulating part adopts a ceramic body.
The cover plate 53 is used for hermetically connecting the electrode rod and the upper cover, and is also provided with an air exhaust opening 55 for communicating with the sterilization pot body, the air exhaust opening performs negative pressure pumping on the sterilization pot body through an external negative pressure air exhaust device, and the negative pressure can increase the sterilization efficiency when plasma sterilization is performed.
The cover plate, the negative pressure air exhaust device, the electrode rod and the plasma power supply are all a whole set of portable device, are convenient to carry and wide in universality, and are suitable for all metal cans.
The use method during sterilization comprises the following steps:
firstly, the articles to be sterilized are put into the placing table 40 in the sterilizing pot body, and the upper cover is covered. Then heating is carried out through the heating device 30 to enable steam to be generated in the sterilizing pot body, when the pointer of the pressure gauge reaches 33.78kPa, the exhaust valve is opened to exhaust cold air, the pointer of the pressure gauge descends at the moment, and when the pointer descends to zero, the exhaust valve is closed. The aim is to fully remove cold air, otherwise the temperature in the pot does not reach the specified temperature, and the sterilization effect is influenced.
Heating is continued, steam in the cooker is increased, the pointer of the pressure gauge is raised again, when the pressure in the cooker is increased to the required pressure, the firepower is reduced, the steam pressure is maintained at the required pressure for a certain time according to the characteristics of the sterilized articles, the sterilizer is powered off or the firepower is cut off, and after the sterilizer is naturally cooled, the exhaust valve is slowly opened to remove residual air. After the high-pressure steam sterilization is finished, the air can not be discharged for pressure reduction, otherwise, the liquid in the bottle can be violently boiled, the bottle stopper is flushed away, the liquid overflows and even the container bursts, and the subsequent operation can be carried out only after the pressure in the sterilizer is reduced to be equal to the atmospheric pressure.
And finally, starting the plasma generating mechanism, generating plasma between the electrode rod and the sterilizing pot body, and spreading the plasma to the inside of the whole sterilizing pot body, so that the inside of the whole pot body is subjected to comprehensive plasma sterilization and disinfection. The plasma can be completely killed within 20 minutes after being generated, and the plasma comprises various germs, pathogens, bacteriophage and microorganisms which are difficult to kill at high temperature and high pressure.
