[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In one embodiment, Figure 1-Figure 5 As shown, a sterile storage cabinet for cell culture comprises a box body 1, a flip door 2 is rotatably connected to one side of the open end of the box body 1 through a hinge, a snap-on unit 3 for sealing the flip door 2 is fixedly installed between the flip door 2 and one side of the box body 1, an observation window 4 is rotatably connected to the inner wall of one side of the box body 1 close to the flip door 2 through a hinge, a switch unit 5 for sealing the observation window 4 is arranged between one side of the observation window 4 and the open end of the box body 1, a gas concentration control unit 6 and a partition 7 are fixedly installed inside the box body 1, the gas concentration control unit 6 is used to change the concentration of the required gas in the box body 1 according to the culture conditions of different cells, and a plurality of placement grooves 8 with different diameters are provided on the partition 7 so that it can be compatible with and stably place cell culture containers of different sizes;

[0027] A disinfection unit for automatically disinfecting the staff is fixedly installed on the switch unit 5 to simplify the disinfection operation. The disinfection unit includes a sensor 9, which is embedded and installed on the side wall of the switch unit 5 knob. This installation position is the position that the staff must touch when turning the knob to achieve sensitivity and immediacy of the induction. A disinfection nozzle 10 is fixedly installed on the surface of the switch unit 5 knob. A cavity for storing disinfectant is provided inside the circular block of the switch unit 5. The disinfectant is alcohol. This setting can spray alcohol on the hands of the staff for disinfection immediately after the sensor 9 senses.

[0028] A stretching unit for taking out containers is arranged inside the box body 1, and the stretching unit includes a plurality of slide grooves 11, which are symmetrically arranged on the inner walls of both sides of the box body 1 and are vertically equidistantly distributed. A slider 12 is slidably connected to the inner side of the slide groove 11, and a hook 13 is fixedly connected to the side wall of the slider 12. Each group of hooks 13 corresponding to the two sides are respectively sleeved in the grooves on both sides of the partition 7 to place the partition 7 firmly. The inner wall of one end of the slide groove 11 close to the flip door 2 and the end wall of the slider 12 close to the flip door 2 are fixedly embedded with magnets 14. The attraction of the two magnets 14 can increase the stability of the partition 7 when it is pulled out, so as to facilitate the operation of taking out the container;

[0029] Example 2

[0030] A handle assembly is provided at one end of the top of the partition 7 for the convenience of the staff to pull the partition 7. The handle assembly includes two fixing seats 15, which are symmetrically distributed at the top of the partition 7. A handle 16 is rotatably connected between the two fixing seats 15. Torsion springs 17 are fixedly connected between the two sides of the handle 16 and the side walls of the corresponding fixing seats 15. The torsion springs 17 are used to automatically rotate the handle 16 back to a vertical state after use to prevent the closing of the observation window 4 from being affected.

[0031] A temperature control screen 18 for controlling the internal temperature of the box 1 is fixedly mounted on one side outer wall of the box 1, so as to control and adjust the temperature inside the box 1 in real time according to different requirements of cultured cells, so as to improve the professionalism of cultured cells.

[0032] Working principle: When the staff uses this storage cabinet device, they can first turn the nut to open the flip door 2, conduct a preliminary observation of the cells inside the box body 1 through the observation window 4, and then turn the knob on the switch unit 5 to open the observation window 4. When turning the knob, the hand will touch the sensors 9 on both sides of the knob, and the sensors 9 will automatically control the disinfection nozzle 10 to spray alcohol on the hand, thereby facilitating the disinfection operation; after opening the observation window 4, the handle 16 can be pulled outward by hand, and the handle 16 will drive the partition 7 to move outward synchronously through the fixed seat 15, and the hooks 13 and the slider 12 hooked on both sides of the partition 7 will also move synchronously along the slide groove 11, so that it is convenient to take the container placed on the partition 7 close to the depth of the box body 1; after the taking operation is completed, the partition 7 is pushed back to the inside of the box body 1, and the handle 16 automatically rotates back to its original position under the action of the torsion spring 17, and then the observation window 4 and the flip door 2 can be closed in turn to ensure the airtight effect of the box body 1.

[0033] The above-mentioned embodiment discloses a sterile storage cabinet for cell culture, in which a disinfection unit is arranged at the knob of the switch unit 5, so that when the sensor 9 senses that the staff has opened the observation window 4, it will automatically control the disinfection nozzle 10 to spray and disinfect the staff's hands, thereby simplifying the disinfection operation; at the same time, by arranging a pulling unit, the staff can pull the partition 7 along the slide groove 11 through the handle 16 to facilitate the removal of containers placed deep in the box body 1.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
