Description

Technical Field

[0001] The utility model relates to the technical field of strain cultivation, and particularly relates to a strain inoculation device. Background Art

[0002] Common bacterial inoculation methods include the streak plate isolation method, the slant inoculation method, and the stab inoculation method. The bacteria are washed off in a solid medium and poured into a liquid medium, or from a liquid culture, the bacterial liquid is transferred to a liquid medium with a pipette, or the bacterial liquid is transferred from a liquid culture to a solid medium.

[0003] In fact, a strain is a sign of a certain microorganism reaching "genetic purity". Once the strain mutates, a new strain name should be marked. When the existing strain inoculation device is used, complicated disinfection means are required, but the inoculation medium is still contaminated, making the strain unusable, thus causing waste of resources. Moreover, during the strain inoculation process, there is a lack of a test tube positioning mechanism, which may cause the test tube to fall during inoculation and even cause contamination. Summary of the Invention

[0004] The purpose of the utility model is to provide a strain inoculation device to solve the above-mentioned defects in the prior art.

[0005] The strain inoculation device includes an inoculation box body. An inoculation box door is hingedly connected to the outside of the inoculation box body. A base is connected to the bottom end of the inoculation box body. A disinfection mechanism is arranged inside the inoculation box body. The disinfection mechanism sterilizes the air and bacteria inside the inoculation box body to avoid the situation that the strain is contaminated by other types of strains during the cultivation process. A positioning mechanism is arranged on one side of the disinfection mechanism. The positioning mechanism positions the test tube for strain cultivation, adjusts the distance between the supporting devices according to the size of the test tube, and drives the test tube to rotate for disinfection at the same time.

[0006] Preferably, the disinfection mechanism includes a motor, a suction box body, an exhaust mesh plate, an air inlet pipe component, an ultraviolet lamp, and a fan blade. The motor is arranged on the top end of the inoculation box body. The output end of the motor is axially connected with the fan blade. One side of the suction box body is penetrated and connected with the exhaust mesh plate. The bottom end of the suction box body is penetrated and connected with the air inlet pipe component. An ultraviolet lamp is arranged on one side of the suction box body.

[0007] Preferably, the air inlet pipe component is communicated with the inside of the inoculation box body through one side penetrating and connecting the suction box body.

[0008] Preferably, the positioning mechanism includes a transmission gear, a threaded column, a tray, an inner tooth sleeve block, and a material supporting tube. The top ends of a set of the transmission gears are connected through the output end of a motor, the bottom ends of the other set of the transmission gears are connected with a tray, the outer side of the tray is equidistantly penetrated and connected with the material supporting tubes, the outer side of the tray is penetrated and connected with the inner tooth sleeve block, and a threaded column is connected inside the inner tooth sleeve block.

[0010] Preferably, the motor is in meshing connection with the top transmission gear of the tray through the transmission gear connected to the output end.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. During use, the inner tooth sleeve block and the tray are positioned by the suspended threaded column. During use, on the one hand, the motor drives the transmission gear to rotate, the transmission gear drives the tray to rotate, and then the rotating tray contacts with the ultraviolet lamp arranged on one side to uniformly disinfect the surface of the tray and the test tube. On the other hand, an operator holds the inner tooth sleeve block and the tray and rotates them on the outer side of the threaded column to adjust the distance between the two trays, so as to facilitate the positioning of the strain test tubes on multiple trays.

[0013] 2. When the internal equipment needs to be disinfected, while the motor drives the tray to rotate, the fan blades are used to inhale air, and then the inhaled air is filtered to avoid introducing other types of germs into the device during the injection of external air, resulting in contamination of the strains.
