[0002] The steam sterilizer used for biological flora experiments, also known as a sterilizer or high-pressure steam sterilizer, is a closed double-layer metal pot that can withstand a certain pressure. Its working principle is to use electric heating wires to heat water to generate steam, and by maintaining a certain pressure, the boiling point and temperature of the water in the pot are increased accordingly, thereby achieving the purpose of high-temperature sterilization. This type of equipment usually consists of a sealed barrel, a pressure gauge, an exhaust valve, a safety valve and an electric heating wire. Among them, the function of the safety valve is to release the pressure when it exceeds the rated pressure to ensure the safe operation of the equipment. The pressure gauge is used to indicate the pressure display in the pot to help operators understand the working status of the equipment.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1: This embodiment is intended to promote the solution of the problem that most of the steam sterilizers used in the prior art for biological flora experiments use a one-time snap-fit method to seal the boiler, which may cause the snap-fit seal to be not firm enough. When the snap-fit is not firm enough, it may affect the sterilization effect. Please refer to Figure 1-Figure 8 A steam sterilizer for biological flora experiments includes a pot body 110 and a placement frame 180. The placement frame 180 is placed inside the pot body 110. A pot cover 120 is threadedly connected to the pot body 110 through a mounting block 190. A first slot 140 is opened on the side of the pot cover 120. A second slot 330 is axially symmetrically arranged on the side of the first slot 140. A first fixing rod 130 is inserted in the middle of the first slot 140. A second fixing rod 260 is inserted in the middle of the second slot 330. A first mounting slot 150 is opened on the side of the first slot 140. A second mounting slot 340 is opened on the side of the second slot 330.
[0027] A first clamping rod 200 is fixedly connected to the bottom of the first fixing rod 130, and the first clamping rod 200 is plugged into the first clamping slot 140. A first clamping block 220 is placed in the middle of the first installation slot 150, and a first connecting block 250 is fixedly connected to the middle of the first clamping block 220. A first pulley 230 is installed on the side of the first connecting block 250 through a first bearing 240. The first pulley 230 slides in the middle of the first installation slot 150. When the steam sterilizer is in use, the pot cover 120 is first opened, and the objects to be sterilized are placed in the placement frame 180, and then the placement frame 180 is placed in the middle of the pot body 110, and the pot cover 120 is snap-connected with the pot body 110 to sterilize the objects.
[0028] When it is necessary to engage the pot cover 120 with the pot body 110, the pot cover 120 is directly connected to the pot body 110 through threads, and then the first fixing rod 130 and the second fixing rod 260 are engaged with the first clamping groove 140 and the second clamping groove 330 respectively. When the first fixing rod 130 and the second fixing rod 260 are respectively plugged into the first clamping groove 140 and the second clamping groove 330, the first clamping rod 200 at the bottom of the first fixing rod 130 and the second clamping rod 270 at the bottom of the second fixing rod 260 will push the first clamping block 220 and the second clamping block 310. At this time, the first clamping block 220 and the second clamping block 310 will be engaged with the first limiting groove 160 and the second limiting groove 320 respectively, so that the pot body 110 and the pot cover 120 can be tightly engaged. By setting the first sealing ring 360 and the second sealing ring 370, the first fixing rod 130 and the second fixing rod 260 are sealed after being plugged in.
[0029] When the pot cover 120 needs to be opened, the first fixing rod 130 and the second fixing rod 260 are first moved out of the first card slot 140 and connected with the first installation slot 150, and the second card slot 330 is connected with the second installation slot 340. The first card slot 140 and the second card slot 330, the first card slot when the first fixing rod 130 and the second fixing rod 260 are moved out, the first card rod 200 and the second card rod 270 will move upward, and the first card block 220 and the second card block 310 will not be blocked. The first spring 210 and the second spring 350 can push the first card block 220 and the second card block 310 out of the first limiting groove 160 and the second limiting groove 320. At the same time, the high pressure in the pot body 110 can be released, and then the pot cover 120 can be opened.
[0030] In the present embodiment: the steam sterilizer for biological flora experiments, through the threaded connection between the pot cover 120 and the pot body 110, makes it easier to engage and disassemble the pot body 110 and the pot cover 120. At the same time, through the arrangement of the first fixing rod 130 and the second fixing rod 260, the engagement connection between the pot body 110 and the pot cover 120 is tighter, which solves the problem that most of the prior art steam sterilizers for biological flora experiments mentioned in the background technology adopt a one-time engagement method to seal the boiler, which may result in the problem that the engagement seal is not firm enough. When the engagement is not firm enough, the sterilization effect may be affected. Through the arrangement of the first sealing ring 360 and the second sealing ring 370, after the first fixing rod 130 and the second fixing rod 260 are plugged in, the joint is sealed as much as possible, thereby improving the sterilization effect.
