[0002] Biological experiments are a fundamental method of biological research. They utilize specific instruments, materials, and reagents to observe and study the structure, function, genetics, and environmental relationships of organisms under controlled conditions. These experiments aim to verify scientific theories, explore unknown phenomena, and cultivate students' practical skills and scientific thinking. Through biological experiments, we can gain a deeper understanding of the mysteries of life and provide scientific evidence and technical support for fields such as medicine, agriculture, and environmental protection.

[0003] In biological experiments, experimental equipment, culture media, reagents and other items need to be strictly sterilized to ensure the accuracy and safety of the experiment. For this purpose, a steam sterilizer for biological experiments is needed.

[0004] Currently, steam sterilizers usually place laboratory instruments and materials directly on a steam filter, heat the steam at high temperature, and use the steam to sterilize the laboratory instruments and materials. However, in actual use, the laboratory instruments are simply placed directly and remain motionless, resulting in insufficient contact between the high-temperature steam and the laboratory instruments and materials. Steam is not easy to enter the interior of some laboratory instruments with bottle mouths, resulting in low disinfection efficiency and general disinfection effect. Therefore, a steam sterilizer for biological experiments is proposed to solve the above problems. Utility Model Content

[0033] Reference Figure 2-Figure 4The top of the passive bevel gear 9 is fixedly connected with a circular sleeve 10 which plays a fixed connection role. The outer circumference of the circular sleeve 10 passes through and is rotatably connected to the bottom of the steam pot 2. The top of the circular sleeve 10 is fixedly connected with a rotating disc 11, thereby driving the rotating disc 11 to rotate in the same direction and speed as the passive bevel gear 9. The reciprocating screw 5 passes through the interior of the passive bevel gear 9, the circular sleeve 10, and the rotating disc 11 in sequence. The top of the rotating disc 11 is clamped with a sleeve 12. The sleeve 12 is provided with two groups, which are symmetrically arranged on the left and right sides of the rotating disc 11. The inside of the sleeve 12 is slidably connected with a sliding rod 13. The sliding sleeve 12 limits the sliding rod 13 to slide up and down only along the inner wall of the sliding sleeve 12.

The outer periphery of the sleeve 12 is slidably connected to the inside of the positioning slot 22. At this time, the sleeve 12 is clamped in the inside of the positioning slot 22, so that the rotation of the rotating disc 11 can drive the sleeve 12 to rotate along the center of the rotating disc 11.

[0035] Working principle: When you want the steam to fully contact the experimental equipment, place the experimental equipment on the top of the steam filter 14, and then turn on the rotating motor 4. The output shaft at the top of the rotating motor 4 will drive the reciprocating screw 5 to rotate, and the reciprocating screw 5 drives the active bevel gear 6 to rotate. The active bevel gear 6 drives the passive bevel gear 9 to rotate in the opposite direction of the reciprocating screw 5 through the transmission bevel gear 7. The passive bevel gear 9 drives the rotating disc 11 to rotate through the circular sleeve 10. The rotating disc 11 drives the steam filter 14 to rotate through the sleeve 12 and the sliding rod 13. The steam filter 14 drives the threaded block 16 to rotate through the partition rod 15 and the limit assembly, and the rotation direction of the threaded block 16 is opposite to that of the reciprocating screw 5, so that the threaded block 16 drives the steam filter 14 to move up and down, so that the steam filter 14 drives the experimental equipment up and down while rotating, thereby ensuring that the inner wall of the experimental equipment can fully contact with the steam, thereby improving the disinfection efficiency and disinfection effect. When you want to remove the steam filter 14 conveniently and clean the scale inside, push the limit block 20 outward, and the limit block 20 moves outward along the limit groove 18, while compressing the limit spring 19, so that the limit block 20 is disengaged from the inside of the card groove 21, releasing the limit of the partition rod 15 and the threaded round block 16, and lifting the steam filter 14 upward, driving the sleeve 12 to slide out of the positioning groove 22, so that the steam filter 14 can be easily taken out and the internal scale can be easily cleaned.
