[0024] Example

[0025] The current anaerobic incubators and the anaerobic incubators produced at home and abroad in this industry have a gap between the door 3 provided on the front side and the front opening of the incubator, which leads to air leakage. As a result, when the air supply is stopped, the oxygen content in the operating room of the incubator can be maintained at 0.1% for a short time, and cannot be maintained for a long time, which may cause necrosis of the cultured anaerobic bacteria.

[0026] Secondly, when the anaerobic incubator needs to be moved later, there is no structure to facilitate its movement. It is common to only set rollers 53 around the bottom, which cannot ensure the stability of the anaerobic incubator when it is placed.

[0027] To do this, see Figure 1-3 The utility model provides an anaerobic incubator capable of stopping gas replenishment for a short period of time, comprising: an equipment support cabinet frame 2 installed at the bottom of an anaerobic incubator equipment body 1, two symmetrically arranged box doors 3 are arranged on the front side of the anaerobic incubator equipment body 1, the lateral vertical sections of the box doors 3 are all convex structures, and the tops of the box doors 3 are rotatably connected to the front side of the anaerobic incubator equipment body 1 through two hinges 31, and two symmetrically arranged pneumatic sealing structures 4 are installed on the top of the anaerobic incubator equipment body 1. After the box door 3 is closed, the pneumatic sealing structure 4 can be expanded and sealed by inflating, thereby greatly improving the sealing and anti-leakage effect;

[0028] It also includes a portable moving structure 5, which is installed on the equipment support cabinet 2. When the equipment body needs to be moved, the portable moving structure 5 can be replaced to assist the anaerobic incubator equipment body 1 to move.

[0029] Among them, the anaerobic incubator adopts the latest developed new generation large-screen true color touch screen microcomputer controller, which is set in the middle of the main body of the equipment. It can accurately and intuitively control the incubator temperature and O2 gas concentration, and uses PLC as the core controller. At the same time, the interior of the equipment is supplemented with high-precision temperature sensors, oxygen sensors, pressure sensors, temperature control modules, gas control modules, and pressure control modules. The control accuracy is high, the stability is good, and the safety is high; the humanized human-machine interface facilitates the operator to monitor the process data in real time, and it is equipped with a USB interface. All of the above can be implemented through existing technical means, and no specific description is made here.

[0030] Further Figure 1-3 As shown, in order to achieve the sealing and leakage prevention between the cabinet door 3 and the gap between it and its opening by inflating the sealed inflatable air ring 45, a pneumatic sealing structure 4 is provided, including a groove opened on the periphery of the cabinet door, in which a sealed inflatable air ring 45 with a mouth-shaped structure in vertical section is bonded, and a telescopic air pipe 44 is connected to the air inlet of the sealed inflatable air ring 45, and the other end of the telescopic air pipe 44 extends from the inner side of the cabinet door to the outer side of the cabinet door, and is connected to the bottom air outlet of the air cylinder 42, and the air cylinder 42 is fixed to the inner top wall of the anaerobic incubator equipment body 1, and a piston block 43 is slidably connected in the air cylinder 42, and the piston block 43 squeezes the air preset at the bottom to make it enter the sealed inflatable air ring 45 to achieve the expansion of the sealed gap, and an electric push rod 41 is fixed to the top of the anaerobic incubator equipment body 1, and the electric push rod 41 movably penetrates into the air cylinder 42 and is fixed to the top of the piston block 43.

[0031] The arrangement of the telescopic air tube 44 ensures that the door 3 is not interfered when it is opened, and the telescopic air tube 44 can be stretched and extended when the door 3 is opened.

[0032] Further Figure 1-3 As shown, in order to facilitate the movement of the device body, a convenient movable structure 5 is provided, including two symmetrically arranged U-shaped guide rods 51 fixed on the inner top wall of the device support cabinet frame 2, and the outer sides of the two U-shaped guide rods 51 are movably sleeved with n-shaped movable frames 52, and the two side walls of the two n-shaped movable frames 52 are rotatably connected with rollers 53, and the two n-shaped movable frames 52 are threadedly connected with screws 54, and the top ends of the screws 54 are rotatably connected to the inner top wall of the device support cabinet frame 2, and the bottom ends of the screws 54 are fixed with worm wheels 55, and one side of the worm wheels 55 is meshingly connected with worms 56, and the same transmission shaft 57 is fixed in the mounting shafts of the two worms 56, and the middle part of the transmission shaft 57 is rotatably connected to the device support cabinet frame 2, and the two ends of the transmission shaft 57 are respectively rotatably connected to the device support cabinet frame 2 through bearing seats, and one end of the transmission shaft 57 extends to the outside of the bearing seat and is fixed with a handwheel 58.

[0033] The self-locking effect of the worm wheel 55 and the worm 56 ensures that after the two screws 54 are rotated, they will not rotate due to the gravity of the device body.

[0034] Embodiment: After closing the cabinet door, the electric push rod 41 is started to push the piston block 43 downward, so that the piston block 43 squeezes the air in the air cylinder 42 downward, so that the air enters the sealed inflatable air ring 45 through the telescopic air pipe 44, thereby expanding in the groove, and then the gap between the opening and the cabinet door 3 can be sealed, effectively greatly reducing the speed of oxygen leakage, so that the oxygen content can be maintained at 0.1% for a long time, avoiding the phenomenon that may cause necrosis of cultured anaerobic bacteria;

[0035] Secondly, when the equipment needs to be moved, the transmission shaft 57 can be rotated by the hand wheel 58, so that the two worms 56 can be rotated, and the worm wheels 55 can be driven respectively, so that the two screws 54 can be rotated. Since the screws 54 are threadedly connected to the n-type movable frames 52, the two n-type movable frames 52 can be moved down synchronously, and the four rollers 53 can contact the ground, and the equipment can be lifted as a whole, so as to facilitate the subsequent movement and transportation of the equipment and be easy to use.
