[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1-6As shown, a biological safety cabinet for sample storage includes a cabinet body 1, an inner cavity 2 is provided on the cabinet body 1, and a movable door 3 is provided on the cabinet body 1, an ozone generator 4 is provided inside the cabinet body 1, and the ozone generator 4 is provided with a connecting plate 5 and a supporting spring 8, an inner wall of the cabinet body 1 is provided with a mounting structure 7, and the mounting structure 7 is connected to the connecting plate 5, an outer wall of the cabinet body 1 is provided with a mounting frame 10, and a filter 9 is provided on the outer wall of the cabinet body 1 through the mounting frame 10, an air vent 11 is provided at the mounting frame 10 on the cabinet body 1, and the cabinet body 1 is provided with a bracket 12 at the lower end, a controller 13 is installed on the cabinet 1, a U-shaped hole 6 is opened on the connecting plate 5, and the connecting plate 5 is connected to the mounting structure 7 through the U-shaped hole 6, the supporting spring 8 contacts the inner wall of the cabinet 1, and the mounting structure 7 includes a fixing seat 701, a guide rod 702, a movable groove 703, a screw hole 704, a plug 705, an end plate 706, a stud 707, a first spring 708 and a tightening plate 709, the guide rod 702 is arranged inside the fixing seat 701, the movable groove 703 is set Between the fixing seat 701 and the guide rod 702, the screw hole 704 is opened on the guide rod 702, the cannula 705 is fixedly connected to the end plate 706, and the cannula 705 is inserted into the movable groove 703, the stud 707 is fixed inside the cannula 705, and the stud 707 is threadedly connected to the screw hole 704, the first spring 708 is fixedly connected to the tightening plate 709, and the first spring 708 and the tightening plate 709 are sleeved on the cannula 705, and the end of the first spring 708 is connected to the end plate 706. The generator 4 is provided with a connecting plate 5 and a supporting spring 8. The ozone generator 4 is installed by using the mounting structure 7 in conjunction with the connecting plate 5. The installation of the ozone generator 4 is completed by hanging and tightening, making the installation or disassembly of the ozone generator 4 extremely convenient and can be achieved without operating multiple screws. The operation is flexible and convenient, saving time and effort. The stud 707 inside the tube 705 is connected to the screw hole 704, and the tightening effect on the connecting plate 5 can be adjusted, making it more adaptable to use.

[0021] When using the biosafety cabinet, the ozone generator 4 is installed through the connecting plate 5 and the mounting structure 7. During this process, the connecting plate 5 is sleeved onto the cannula 705 in the mounting structure 7 through the U-shaped hole 6. The abutting plate 709 contacts the connecting plate 5 under the action of the first spring 708. At the same time, the connecting plate 5 contacts the fixing seat 701, and the cannula 705 is rotated through the end plate 706. The stud 707 rotates and moves in the screw hole 704, thereby moving the end plate 706 and the cannula 705 along the guide rod 702, and the cannula 705 moves in the movable groove 703. At the same time, the first spring 708 and the abutting plate 709 move together, and the compression degree of the first spring 708 becomes greater and greater, and the force on the abutting plate 709 becomes greater and greater until the connecting plate 5 is firmly abutted against the cannula. On 705, the supporting spring 8 contacts the inner wall of the cabinet 1, thus completing the installation of the ozone generator 4. After installing the filter 9 at the mounting bracket 10, the safety cabinet is started. Before use, the movable door 3 is in a closed state, and the ozone generator 4 is started by the controller 13. The ozone generator 4 runs to disinfect and sterilize the inner cavity 2. After the disinfection and sterilization is completed, wait for a period of time, then open the movable door 3, put the biological sample into the inner cavity 2 and close the movable door 3. During the storage of the biological sample, air enters the cabinet 1 from the air vent 11, thereby achieving the purpose of air circulation. In the process of air entering, the filter 9 plays a purification and disinfection effect, preventing the external environment from affecting the purity of the biological sample, thereby ensuring the accuracy of subsequent experiments.

[0022] According to the above embodiment, the filter 9 includes a frame 901, a filter element 902, a sealing connection frame 903, a mounting plate 904, a mounting bolt 905, a slot 906, an elastic sealing strip 907, a rubber column 908 and a second spring 909. The filter element 902 is installed in the frame 901, the sealing connection frame 903 is fixedly connected to the frame 901, the mounting bolt 905 is provided on the mounting plate 904, and the mounting plate 904 is fixed on the sealing connection frame 903, the slot 906 is opened on the sealing connection frame 903, and the elastic sealing strip 907 is fixed to the frame 901. The elastic sealing strip 907 is fixedly connected to the rubber column 908, and the elastic sealing strip 907 and the rubber column 908 are arranged in the slot 906. The second spring 909 is sleeved on the rubber column 908, and the filter 9 is placed outside the cabinet 1 to facilitate disassembly and maintenance. The mounting frame 10 is connected in the slot 906 and contacts the elastic sealing strip 907, which can ensure that the entire filter 9 installation area has good sealing performance, and ensure that the air only circulates from the filter element 902 between the frames 901, thereby ensuring the air purification effect.

[0023] When installing the filter 9, the sealing connecting frame 903 at one end of the frame 901 is set on the mounting frame 10, and the mounting bolts 905 on the mounting plate 904 are used to fix the entire filter 9. At this time, the mounting frame 10 is inserted into the slot 906, and the mounting frame 10 contacts the elastic sealing strip 907. The second spring 909 is in a compressed state. Under the action of the second spring 909 on the rubber column 908, the elastic sealing strip 907 is in close contact with the mounting frame 10 and has a certain elastic deformation, thereby sealing the portion where the sealing connecting frame 903 is connected to the mounting frame 10. After the filter 9 is installed and put into use, the air passes through the filter element 902 into the cabinet 1, and the filter element 902 plays a role of purification and disinfection. When necessary, the filter 9 can be quickly disassembled for replacement and other operations, which is convenient and quick to operate.
