Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in the attached figure 1, the utility model provides a portable pressure steam sterilizer, which comprises an outer barrel 1 and an inner barrel 2 arranged in the outer barrel 1, wherein the bottom surface and the side surface of the inner barrel 2 are integrally formed with the outer barrel 1, the bottom surface of the inner barrel 2 is provided with an electric heating device 7, the electric heating device 7 can be a heating rod commonly used by sterilizers, the top of the inner barrel 2 protrudes out of the upper surface of the outer barrel 1, the upper end surface of the inner barrel 2 is provided with an annular first sealing strip 41 and a first sealing groove concentrically arranged with the first sealing strip 41, a first rubber pad 52 is arranged in the first sealing groove, the inner barrel 2 is further provided with a barrel cover 3, the barrel cover 3 is provided with a second sealing groove corresponding to the first sealing strip 41, a second rubber pad 51 is arranged in the second sealing groove, the barrel cover 3 is further provided with a second sealing strip 42 corresponding to the first sealing groove, the cylinder cover 3 and the inner cylinder 2 are fixed through a plurality of swing bolts 6, and a cooling device is arranged in the outer cylinder 1.

The cooling device comprises a cooling liquid storage tank 9 and a heat exchange tube 10 spirally wound outside the inner barrel 2, wherein the cooling liquid storage tank 9 is communicated with the heat exchange tube 10 through a circulating pump (not shown in the figure). When the sterilizer is in a sterilization state, no cooling liquid is present in the heat exchange tube 10. After the sterilization is finished, the circulating pump is started to fill the heat exchange tube 10 with the cooling liquid, so that the cooling liquid and the inner tube 2 exchange heat, and the heat dissipation of the inner tube 2 is accelerated. When the temperature drops to the temperature that the sterilizer can be opened, the circulating pump pumps the cooling liquid in the heat exchange tube 10 into the cooling liquid storage tank 9 again, so as to ensure that no cooling liquid remains in the heat exchange tube 10 during the next sterilization. (if there is cooling liquid in the heat exchange tube 10 during sterilization, the cooling liquid will absorb the heat of the inner tube 2, so that the temperature rising speed thereof is slowed, the sterilization efficiency is affected, and if the cooling liquid is heated along with the inner tube 2, the cooling effect after sterilization will be greatly reduced) to save volume, and the circulation pump can adopt a micro circulation pump.

The inner cylinder 2 is of a circular truncated cone-shaped structure with a large upper part and a small lower part, or the bottom of the inner cylinder 2 is provided with a circular step. FIG. 1 is a schematic structural diagram of an inner cylinder 2 provided with circular steps.

The inner barrel 2 is internally provided with a steaming plate 8, and a plurality of air holes are uniformly distributed on the steaming plate 8. The inner barrel 2 is large at the top and small at the bottom or is provided with steps, so that the steaming plate 8 can be placed in the inner barrel 2 more stably, and a certain space for containing water is reserved below the steaming plate. Water is filled into the inner cylinder 2, the water amount is controlled to be below the steaming plate 8, when the water is heated, the water is continuously vaporized, the water vapor content is increased, and the air pressure in the inner cylinder 2 is increased accordingly. When the temperature and the air pressure both meet the sterilization requirements, the sterilization can be finished.

The central position of the steaming plate 8 is provided with a lifting rod 11 protruding upwards, and the tail end of the lifting rod 11 is provided with an anti-skid handle 12. In the existing sterilizer, if a plurality of utensils are sterilized at the same time, it is difficult to take out the utensils at the same time. And because the inner cylinder 2 is made of metal, the hand is easily scalded when the vessel is taken out. The utility model provides a steam 8 center departments of board and set up portable pole 11, then can perfectly solve above-mentioned problem. After the sterilization is finished, a plurality of utensils can be taken out simultaneously only by stably lifting the lifting rod 11, and the hands can not touch the inner wall of the inner barrel 2, so that scalding is effectively avoided.

A plurality of hinged supports 13 are uniformly distributed on the circumference of the top of the inner cylinder 2, the hinged supports 13 are rotatably connected with a rotating shaft, the eyelet bolt 6 is fixed on the rotating shaft, a fixing lug 14 corresponding to the hinged support 13 is arranged on the cylinder cover 3, and an opening for clamping the eyelet bolt 6 is arranged on the fixing lug 14. The swing bolt 6 is also connected with a nut in a threaded manner.

The inner wall of the cylinder cover 3 is a cambered surface with low circumference and high middle. The inner wall of the cylinder cover 3 is generally a plane, and the cambered surface is arranged to enable water vapor to be gathered towards the periphery of the cylinder cover 3 during condensation, so that the water vapor is prevented from dripping into a sterilized utensil.

The cylinder cover 3 is provided with a safety valve, an air release valve and a pressure gauge, and the bottom of the outer cylinder 1 is provided with a water outlet tap (not shown in the figure) communicated with the bottom of the inner cylinder 2.
