Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide incubators, and more particularly to carbon dioxide incubators. Background Technology

[0002] A carbon dioxide incubator is a device that simulates the in vivo growth environment of cells to culture them in vitro. It consists of an outer door, a transparent inner door, and a main body. Both the outer and inner doors are hinged to the main body and pivot relative to it to facilitate the placement and removal of biological samples. The outer door is located outside the inner door, and the heating element and sealing strip are located on the outer door. When the outer door is closed, the sealing strip surrounds the inner door, is compressed by the main body, and seals against it; the heating element is in contact with the inner door to heat it. For carbon dioxide incubators, opening and closing the outer door must meet certain requirements, such as requiring moderate force to open, ensuring a good seal when closed, and minimizing vibration when closing to avoid affecting the biological samples inside.

[0003] In existing technologies, the compression of the sealing strip is usually achieved by encapsulating a magnetic strip within the entire sealing strip and using magnetic attraction between the outer door and the main body of the enclosure. While this method results in a uniform magnetic force distribution, requires less force to open the outer door, and minimizes vibration when closing it, the magnetic force is relatively weak, the sealing effect is poor, and condensation is prone to occur on the inner door. Utility Model Content

[0004] This utility model provides a carbon dioxide incubator designed to address the issues of force required to open and close the outer door, sealing effect, and vibration.

[0005] In one aspect, a carbon dioxide incubator is provided, comprising an outer door, an inner door, and a main body of the incubator. Both the outer door and the inner door are hinged to the main body of the incubator and can pivot relative to the main body of the incubator. The outer door is located outside the inner door. The CO2 incubator also includes sealing strips, magnetic assemblies, and buffer devices; The sealing strip is installed on the outer door; When the outer door is closed, the sealing strip surrounds the inner door and fits against the main body of the cabinet, while the magnetic assembly and buffer device are located outside the area surrounded by the sealing strip.

[0006] The carbon dioxide incubator of this utility model places the magnet outside the sealing strip, and the outer door and the main body of the chamber are approximately magnetically attracted at a single point. The force of opening and closing the outer door is adjusted by a buffer device, which improves the sealing effect and takes into account the requirements of the force and vibration of opening and closing the outer door.

[0011] The carbon dioxide incubator of this utility model places the magnet outside the sealing strip, and the outer door and the main body of the chamber are approximately magnetically attracted at a single point. The force of opening and closing the outer door is adjusted by a buffer device, which improves the sealing effect and takes into account the requirements of the force and vibration of opening and closing the outer door.

Figure 2 This is another schematic diagram of the carbon dioxide incubator provided in this embodiment of the utility model. Figure 3 yes Figure 2 An enlarged schematic diagram of region A in the middle. Figure 4 This is a schematic diagram of the outer door and magnet assembly provided in an embodiment of this utility model. (In conjunction with...) Figures 1 to 4 The carbon dioxide incubator includes an outer door 1, a transparent inner door 2, a main body 3, a sealing strip 4, a magnetic assembly 5, and a buffer device 6.

[0013] Outer door 1 and inner door 2 are hinged to the main body 3 of the enclosure via rotating shafts, allowing them to pivot relative to the main body 3. When outer door 1 and inner door 2 are closed, outer door 1 is located outside inner door 2, and the heating devices on outer door 1 are in contact with inner door 2 to heat it; inner door 2 and the main body 3 enclose an inner cavity. Multiple horizontal shelves (not shown in the figure) can be installed in the inner cavity for placing biological samples for cell culture experiments; gas flows in the direction of the arrow, forming a gas circulation within the inner cavity. When only outer door 1 is open and inner door 2 is closed, the biological samples can be observed through inner door 2.

[0014] A sealing strip 4 is provided on the outer door 1. Preferably, the sealing strip 4 forms a rectangular surrounding area. When the outer door 1 is closed, the sealing strip 4 surrounds the inner door 2 and fits against the main body 3 of the chamber. The magnet assembly 5 and the buffer device 6 are located outside the area surrounded by the sealing strip 4. When the outer door 1 is closed, the magnet assembly 5 is located on the side of the outer door 1 away from the rotation axis, in the middle of the CO2 incubator, and the buffer device 6 is located on the side of the outer door 1 away from the rotation axis, in the lower half of the CO2 incubator.

[0015] Preferably, the magnet assembly 5 is a single-piece magnet. The magnet assembly 5 is placed outside the sealing strip 4, which reduces the requirements for the manufacturing process of the sealing strip 4; the use of a single-piece magnet makes the magnetic attraction between the outer door 1 and the main body of the box 3 approximately a single point, with a large magnetic attraction force, which is beneficial to improving the sealing effect; the buffer device 6 adjusts the magnetic attraction force to take into account the requirements of the force and vibration of opening and closing the outer door 1.

[0016] In this embodiment of the invention, in the direction of opening or closing the outer door 1, the thickness of the magnet assembly 5 is less than the thickness of the sealing strip 4. When the outer door 1 is closed, the magnetic attraction between the outer door 1 and the main body 3 compresses the sealing strip 4, causing it to fit tightly against the main body 3, thereby improving the sealing effect. Figure 2As shown, the magnet assembly 5 includes a first magnet 51 disposed on the outer door 1 and a second magnet 52 disposed on the main body 3 of the housing. The magnetic poles of the first magnet 51 and the second magnet 52 are opposite. When the outer door 1 is closed, the first magnet 51 is attracted to the second magnet 52. In the direction of opening or closing the outer door 1, the sum of the thicknesses of the first magnet 51 and the second magnet 52 is less than the thickness of the sealing strip 4. Preferably, the first magnet 51 and the second magnet 52 are made of neodymium iron boron, which has high magnetic properties and can withstand high temperatures of 120 degrees Celsius. To prevent the magnets from shattering upon impact when attracted, the magnet assembly 5 also includes a first rubber sleeve 53 fitted onto the first magnet 51 and a second rubber sleeve 54 fitted onto the second magnet 52. The first rubber sleeve 53 and the second rubber sleeve 54 are made of soft rubber materials such as silicone or rubber.

In this embodiment, the buffer device 6 includes a buffer body 61 disposed on the outer door 1 and a top block 62 disposed on the main body 3 of the housing. The buffer body 61 includes a head 611, an adjusting tail 612, an elastic element 613, and a fixing nut 614. The buffer body 61 is fixed to the outer door 1 by the fixing nut 614, and the adjusting tail 612 adjusts the force of the head 611 inserting into the top block 62 by adjusting the compression of the elastic element 613. The elastic element 613 can also be a hydraulic device, etc., and the adjusting tail 612 adjusts the force of the head 611 inserting into the top block 62 by adjusting the pressure of the hydraulic device. The top block 62 is snap-fitted to the main body 3 of the housing. Preferably, the head 611 is made of soft rubber, and the top block 62 is made of plastic. During the process of the head 611 impacting and inserting into the top block 62, the impact strength is guaranteed without producing obvious impact noise.

[0018] The carbon dioxide incubator of this utility model places the magnet outside the sealing strip, and the outer door and the main body of the chamber are approximately magnetically attracted at a single point. The force of opening and closing the outer door is adjusted by a buffer device, which improves the sealing effect and takes into account the requirements of the force and vibration of opening and closing the outer door.
