[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1 , Figure 2 As shown, the utility model provides a technical solution of a sterile biosafety cabinet that is easy to handle waste: comprising a frame 1, a plurality of moving wheels 11 are arranged at the bottom of the frame 1, and the moving wheels 11 are distributed at the corners, a foot pad 12 is arranged on one side adjacent to the moving wheel 11, a cabinet body 13 is arranged on the frame 1, a guide groove 131 is arranged in the cabinet body 13, a cabinet door 2 is arranged in the guide groove 131, a collection box 22 and a handle 24 are installed on the cabinet door 2, a collection box 22 is installed at the bottom of the cabinet body 13, and a bottom of the collection box 22 is provided with a handle 24. A liquid discharge valve 232 is installed on the cabinet 13, and a mesh plate 231 is installed on the collecting box 22. A disinfection component is arranged on the upper part of the cabinet 13, and the disinfection component includes an ultraviolet lamp source 31 installed on the cabinet 13. A pump body 33 is installed on the adjacent side of the ultraviolet lamp source 31. The output end of the pump body 33 is connected to an atomizing pipe 34, and an atomizing nozzle 36 is arranged at the bottom of the atomizing pipe 34. The output end of the pump body 33 is connected to a disinfectant suction pipe 32. A plurality of atomizing pipes 34 are arranged, and adjacent atomizing pipes 34 are connected through a connecting pipe 35.

[0022] In this embodiment, when in use, the experimenter can conveniently open the cabinet door 2 by pulling the handle 24 to perform the experiment. During the experiment, the waste generated can fall into the collection box 22 through the mesh plate 231, which prevents the waste from being scattered inside the biosafety cabinet and reduces the risk of cross contamination. When the waste in the collection box 22 accumulates to a certain extent, the experimenter can take out the collection box 22 by pulling the handle 24 and clean up the waste. The liquid discharge valve 232 at the bottom of the collection box 22 can conveniently discharge the liquid in the waste, which is convenient for the disposal of the waste.

[0023] At the same time, a disinfection component is also provided to disinfect and sterilize the interior of the biosafety cabinet. The disinfection component includes an ultraviolet light source 31, a pump body 33, an atomizing pipe 34, and an atomizing nozzle 36. The pump body 33 can extract the disinfectant from the disinfectant suction pipe 32, and spray it inside the biosafety cabinet through the atomizing pipe 34 and the atomizing nozzle 36, thereby achieving all-round disinfection. The provision of multiple atomizing pipes 34 can further improve the disinfection effect, so that the disinfectant can be sprayed more evenly inside the biosafety cabinet, covering every corner inside the biosafety cabinet, thereby improving the disinfection effect.

[0024] In addition, the utility model further provides a shell 4, on which a positioning column head 41 and a spring 42 are provided, which can cooperate with the positioning groove 21 on the cabinet 13, so that the cabinet door 2 can be tightly closed on the cabinet 13, ensuring the sterility of the experimental environment.

[0025] The utility model has the advantages of easy waste treatment, good disinfection effect, convenient operation, etc., and is suitable for various biological experimental sites, providing a safer, more efficient and convenient experimental environment for experimenters. At the same time, the utility model also has the characteristics of simple structure and easy maintenance, which reduces the use cost and maintenance cost, and has high practicality and promotion value.

[0026] like Figure 1 and Figure 3 As shown, a positioning groove 21 is provided on the cabinet door 2 located in the guide groove 131, and a shell 4 is installed on the cabinet body 13, a spring 42 is provided in the shell 4, and a positioning column head 41 is installed on the end face of the spring 42, the positioning column head 41 passes through the shell 4 and the cabinet body 13, and is slidably connected thereto, and the positioning column head 41 cooperates with the positioning groove 21.

[0027] In this embodiment, when in use, the user can open or close the cabinet body 13 by pushing the cabinet door 2. When the cabinet door 2 is in a closed state, the positioning groove 21 cooperates with the positioning column head 41, so that the cabinet door 2 is firmly maintained in the closed position. The positioning column head 41 is always maintained in the positioning groove 21 by the elastic force of the spring 42, thereby ensuring the tightness of the cabinet door 2.

[0028] When the cabinet door 2 needs to be opened, the user can apply a certain force to overcome the elastic force of the spring 42, so that the positioning column head 41 is disengaged from the positioning groove 21. As the user pushes, the cabinet door 2 slides along the guide groove 131 until it is fully opened. At this time, the user can easily access the items in the cabinet body 13.

[0029] When closing the cabinet door 2, the user only needs to push the cabinet door 2 back to its original position along the guide groove 131, and the positioning column head 41 will automatically enter the positioning groove 21 under the elastic force of the spring 42, thereby completing the closing action of the cabinet door 2. This design makes the opening and closing operation of the cabinet door 2 simple and convenient, and also improves the sealing and stability of the cabinet door 2.

[0030] This embodiment achieves automatic positioning and stable closing of the cabinet door 2 by cleverly utilizing the cooperation between the spring 42 and the positioning groove 21 , thereby improving the convenience and safety of using the cabinet body 13 .
