[0002] Microorganisms are widely present in the surrounding environment, some of which are pathogenic microorganisms. In order to prevent infection, medical workers must strictly implement aseptic operations, disinfect and sterilize the items used and the working environment, and ensure the normal medical and scientific research. Disinfection and sterilization mainly use physical and chemical factors to hinder the main metabolism of microorganisms, or denature and coagulate bacterial proteins, or destroy their genetic material, leading to the death of microorganisms.
[0003] However, due to the various specifications of the laboratory's testing instruments, medical staff cannot ensure that the instrument is in the center area of the fixed cylinder during sterilization, which leads to low sterilization efficiency. In the process of detection, the number of bacteria in a certain area of the instrument will inevitably increase. At this time, it is necessary to focus on disinfecting a certain part of the instrument. Although the purpose of overall sterilization can be achieved by extending the placement time, this sterilization method for certain parts of the instrument will not only reduce efficiency, but may also affect the service life of the instrument.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Reference Figures 1 to 10 The invention discloses an infrared sterilization device for microorganisms in a laboratory, comprising a base 1, a connecting rod 12 is fixedly installed on one side of the upper end of the base 1, and a controller 11 is installed on the other side. The controller 11 is a prior art and is used to control the operation of the device as a whole. A shell 13 is fixedly installed on the top of the connecting rod 12, and a plurality of holes for weight reduction are provided on the surface of the shell 13. A fixed cylinder 2 is fixedly installed inside the shell 13, and an infrared emitter 14 is fixedly installed at one end inside the fixed cylinder 2.
[0022] A mounting groove is provided on one side of the surface of the shell 13, and two sets of fixing plates 21 fixedly installed on the outer surface of the fixing cylinder 2 are arranged in the mounting groove. A motor 22 is fixedly installed on the fixing plate 21, and the output end of the motor 22 is keyed to a driving wheel 23. The outer surface of the driving wheel 23 is made of rubber or other materials with a high friction coefficient, so that it has a strong friction force. A gear ring 24 is rotatably installed in the side wall of the fixing cylinder 2, and the outer surface of the gear ring 24 is in contact with the driving wheel 23, so that when the motor 22 is running, the gear ring 24 can be driven to rotate by the friction between the driving wheel 23 and the outer surface of the gear ring 24.
[0023] A plurality of fixed blocks 43 are fixedly installed at equal angles on one side of the fixed cylinder 2, a rotating column 4 is rotatably installed on the fixed block 43, a rotating block 42 is fixedly sleeved on the outer side of the rotating column 4, an arc-shaped fixed reflector 44 is fixedly installed on one end of the rotating block 42 close to the central axis of the fixed cylinder 2, a slot 41 is provided on the end of the rotating column 4 away from the fixed block 43, a plurality of slide rails 3 are fixedly installed at equal angles on the other side of the fixed cylinder 2, the number of the slide rails 3 is the same as the number of the fixed blocks 43 and the positions of the two correspond one to one, an electric slider 31 is slidably installed on the slide rail 3, and a fixed reflector 44 is fixedly installed on the electric slider 31 The connecting block 32 has a gear 33 fixedly mounted on one end of the connecting block 32 close to the slot 41. The gear 33 is located on the inner side of the gear ring 24 and meshed with the gear ring 24. A clamping block 34 is fixedly mounted inside the gear 33. The positions of the clamping block 34 and the slot 41 correspond one to one, so that when the electric slider 31 is running, the gear 33 can be driven to move by the connecting block 32. When the gear 33 moves, the clamping block 34 can be engaged with the slot 41, and the gear 33 can mesh with the gear ring 24. At this time, when the gear ring 24 rotates, the rotating column 4 can be driven to rotate by the gear 33.
[0024] Two groups of symmetrically arranged connecting parts 45 are fixedly installed at both ends of the fixed reflecting plate 44, a connecting shaft 51 is rotatably installed between the two groups of connecting parts 45, a movable reflecting plate 5 arranged in an arc shape is fixedly installed on the connecting shaft 51, a permanent magnet block 52 is fixedly installed on the end of the movable reflecting plate 5 away from the connecting shaft 51, the permanent magnet block 52 is located on the convex side of the movable reflecting plate 5, and an electromagnetic block 53 fixedly installed on the inner wall of the fixed cylinder 2 is arranged on one side of the permanent magnet block 52, the magnetism of the electromagnetic block 53 can be adjusted by the controller 11, so that an attraction or repulsion is generated between the electromagnetic block 53 and the corresponding permanent magnet block 52, so that the movable reflecting plate 5 rotates compared with the fixed reflecting plate 44, and the magnetic strength of each electromagnetic block 53 is individually controlled by the controller 11.
[0025] The specific working principle of the present invention is as follows. When the instrument to be tested needs to be sterilized, the controller 11 is started so that the controller 11 powers on the infrared emitter 14. After the infrared emitter 14 is powered on, infrared rays are generated inside the fixed tube 2. At this time, medical personnel use tweezers and other clamps to place the instrument to be sterilized into the fixed tube 2. The infrared rays generated by the infrared emitter 14 increase the temperature inside the fixed tube 2, thereby killing the bacteria, thereby achieving the sterilization effect.
[0026] When a certain area of the instrument needs to be sterilized, the position that needs to be sterilized is transmitted to the controller 11. At this time, the controller 11 will start the electric slider 31 corresponding to the position that needs to be sterilized, so that the electric slider 31 slides from the outside to the inside along the inner wall of the slide rail 3. The sliding of the electric slider 31 will drive the gear 33 to move synchronously through the connecting block 32. The movement of the gear 33 will drive the block 34 to move synchronously, so that the block 34 is engaged with the slot 41 provided on the rotating column 4. At the same time, the gear 33 will enter the gap of the teeth on the gear ring 24 when it slides. At this time, the motor 22 is started to rotate. The rotation of the motor 22 will drive the driving wheel 23 to rotate. The rotation of the driving wheel 23 will drive the gear ring 24 to rotate along the inner wall of the fixed cylinder 2 through friction. The rotation of the gear ring 24 will mesh with the gear 33, so that the gear 33 rotates along the axis of the connecting block 32, and the rotation of the gear 33 will drive the block 34 to move synchronously. The block 34 is meshed with the card slot 41, so that the rotation of the gear 33 will drive the rotating column 4 to rotate coaxially through the card block 34, so that the rotating column 4 rotates along the inner wall of the fixed block 43, and the rotation of the rotating column 4 will drive the rotating block 42 to move synchronously, so that the rotating block 42 drives the fixed reflecting plate 44 to move synchronously, so that the fixed reflecting plate 44 drives the connecting shaft 51 to move synchronously through the connecting piece 45, so that the connecting shaft 51 drives the movable reflecting plate 5 to move synchronously, and then the fixed reflecting plate 44 and the two groups of movable reflecting plates 5 rotate along the axis of the rotating column 4. At this time, the fixed reflecting plate 44 and the movable reflecting plate 5 will deflect the angle of the infrared ray generated, so that the infrared ray reflected by the fixed reflecting plate 44 and the movable reflecting plate 5 can directly act on the instrument parts that need to be sterilized, thereby improving the sterilization efficiency, and at the same time avoiding damage to the detection instrument caused by excessive sterilization, thereby increasing the service life of the detection instrument.
[0027] At the same time, when the key part of the instrument is located in the middle or at both ends of the fixed cylinder 2, the controller 11 energizes the electromagnetic block 53 in the opposite direction of the key sterilization part of the instrument, and makes the electromagnetic block 53 and the permanent magnet block 52 fixedly installed at the lower end of the movable reflector 5 have the same magnetic pole. At this time, a repulsive force will be generated between the electromagnetic block 53 and the permanent magnet block 52. Since the electromagnetic block 53 is fixedly installed inside the fixed cylinder 2 and cannot move, the electromagnetic block 53 will convert the repulsive force into a thrust acting on the permanent magnet block 52. The permanent magnet block 52 is subjected to the thrust and will drive the connecting shaft 51 on the movable reflector 5 along the fixed magnet block 44 on the fixed reflector 44. The inner wall of the fixed connecting piece 45 rotates, and the movable reflecting plate 5 is inclined relative to the fixed reflecting plate 44 at this time, so that the movable reflecting plate 5 reflects the infrared rays to the parts of the testing instrument that need to be sterilized, thereby improving the sterilization efficiency. At the same time, due to the long length of the electromagnetic block 53, when the movable reflecting plate 5 and the fixed reflecting plate 44 rotate along the axis of the rotating column 4, the electromagnetic block 53 can still generate a force on the permanent magnet block 52, so that the device can accurately reflect the infrared rays to the parts of the testing instrument that need to be sterilized through the cooperation of the fixed reflecting plate 44 and the movable reflecting plate 5, thereby further improving the sterilization efficiency.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
