DETAILED DESCRIPTION

[0032] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings. Specific implementation method 1

[0034] A biological bacteria breeding device under this specific implementation method, such as Figure 1-2 As shown, a biological bacteria breeding device includes a bottom support portion 1 and a sealing portion 2;

[0035] The bottom support part 1 includes a support base 101, a raised placement boss 102 is fixedly connected to the axis of the top of the support base 101, a sealing ring 103 is fixedly connected to the top of the support base 101, the outer diameter of the sealing ring 103 is equal to the outer diameter of the support base 101, a sealing groove 105 is left between the inner wall of the sealing ring 103 and the outer surface of the placement boss 102, and the height of the sealing ring 103 is lower than the height of the placement boss 102;

[0036] A culture glass 3 having the same diameter as the boss 102 is placed on the top of the boss 102, and the top of the culture glass 3 is used to culture biological bacteria.

[0037] The sealing part 2 includes a sealing cover 201, the outer diameter of the sealing cover 201 is equal to the outer diameter of the supporting base 101, the inner diameter of the sealing cover 201 is equal to the outer diameter of the placement boss 102, and the bottom of the sealing cover 201 is fixedly connected to a sealing head 202, which is inserted into the interior of the sealing groove 105 to form a seal.

[0038] Through the above technical solution, a placement boss 102 is set at the axis of the top of the support base 101, and the biological strains are cultured on the placement boss 102 or the sealing ring 103 is placed on the top of the placement boss 102 to culture the biological strains. When conducting experimental observations, the concave edge will not interfere with the observation equipment, or the culture glass 3 can be directly taken out and placed in the observation equipment for observation, thereby achieving the effect of convenient observation of the biological strains, and the raised placement boss 102 and the detachable culture glass 3 can both facilitate the removal of the biological strains and the cleaning of the vessel;

[0039] The sealing cover 201 is made of transparent glass or colored glass, and is configured according to the breeding environment of the biological strains. Transparent glass can facilitate observation of the breeding conditions of the biological strains, while colored glass is used to block light for biological strains that need to be protected from light.

[0040] Specifically, the outer surface of the sealing ring 103 is provided with anti-slip grooves 104 .

[0041] Through the above technical solution, the anti-skid pattern 104 is provided on the outer surface of the sealing ring 103 to effectively prevent skidding.

[0042] Specifically, the sealing ring 103 is made of rubber and has elasticity.

[0043] Through the above technical solution, the sealing ring 103 is set to rubber material, which can better improve the hand feel. When the sealing ring 103 is elastic, after the sealing head 202 is inserted into the sealing groove 105, the sealing ring 103 will fit with the outer surface of the sealing head 202 through elasticity to further improve the sealing performance.

[0044] Specifically, the inner wall of the sealing cover 201 is fixedly connected with a limiting pressure ring 203 , and the bottom of the limiting pressure ring 203 applies pressure to the edge of the top of the culture glass 3 to limit the culture glass 3 .

[0045] Through the above technical solution, the purpose of setting a limiting pressure ring 203 inside the sealing cover 201 is to limit the culture glass 3 to prevent the culture glass 3 from flipping over when the entire vessel is moved or tilted, causing the top of the culture glass 3 to contact the inner top of the sealing cover 201 and cause the biological strains to be contaminated. Specific implementation method 2

[0047] A sealing part of a biological bacteria breeding device under this specific implementation method, such as Figure 3 As shown, a cavity 204 is provided between the walls of the sealing cover 201 , and the interior of the cavity 204 is vacuum or filled with gas.

[0048] Through the above technical solution, the interior of the cavity 204 is set to a vacuum, which can effectively isolate the transmission of heat and improve the thermal insulation performance, or fill the interior of the cavity 204 with a gas for thermal insulation to make the temperature inside the sealing cover 201 relatively stable. Specific implementation method three

[0050] A sealing part of a biological bacteria breeding device under this specific implementation method, such as Figure 4 As shown, a cavity 204 is provided between the walls of the sealing cover 201 , the interior of the cavity 204 is vacuum or filled with gas, a gas injection port 205 is provided on the top of the sealing cover 201 , the gas injection port 205 is connected with the cavity 204 , and a sealing plug 206 is provided on the gas injection port 205 to seal the gas injection port 205 .

[0051] Through the above technical solution, the purpose of setting the gas injection port 205 is to facilitate the injection of the required gas into the interior of the cavity 204. When the cultured biological strains need to be kept warm, the gas used for insulation is filled. When the cultured biological strains need to be shielded from light, the colored gas is filled to reduce the light transmittance of the sealing cover 201 to achieve the purpose of shading, thereby achieving the effect of conveniently changing the type of gas filled. Specific implementation method four

[0053] A sealing part of a biological bacteria breeding device under this specific implementation method, such as Figure 5 As shown, a cavity 204 is provided between the walls of the sealing cover 201 . The cavity 204 is open at the bottom, and a light shielding member 207 is inserted into the cavity 204 . The light shielding member 207 is coated with a light-shielding layer.

[0054] Through the above technical solution, an opening is set in the cavity 204 from the bottom, and a shading piece 207 is inserted into the cavity 204 through the opening to shield the sealing cover 201. When in use, the shading piece 207 can be easily disassembled and assembled to remove the shading piece 207 or change the shading piece 207 to a different color or a different transparency. Compared with using gas for shading, the cost is lower, and the outer surface of the shading piece 207 can be written and recorded to clarify the type and time of the cultured biological strains. Compared with writing directly on the outer surface of the sealing cover 201, it is clearer. If writing directly on the outer surface of the sealing cover 201, the written records on the sealing cover 201 are easily damaged due to reasons such as holding.

[0055] When in use, a placement boss 102 is arranged at the axis center of the top of the support base 101, and biological strains are cultured on the placement boss 102 or a sealing ring 103 is placed on the top of the placement boss 102. When conducting experimental observations, the concave edge will not interfere with the observation equipment, or the culture glass 3 can be directly taken out and placed in the observation equipment for observation, thereby achieving the effect of convenient observation of biological strains, and the raised placement boss 102 and the detachable culture glass 3 can both facilitate the removal of biological strains and the cleaning of the vessel;

[0056] By setting a cavity 204 between the walls of the sealing cover 201, and setting the interior of the cavity 204 to be vacuum or filled with gas, it can play a role of heat insulation, and by changing the filled gas, the efficiency of heat preservation and light shielding can be changed, so as to achieve the effect of adapting to different breeding conditions and strains;

[0057] By setting a cavity 204, and setting an opening in the cavity 204 from the bottom, and inserting a shading piece 207 into the cavity 204 through the opening, the sealing cover 201 is shielded from light. When in use, the shading piece 207 can be easily disassembled and assembled to remove the shading piece 207 or change the shading piece 207 to a different color or a different transparency, thereby achieving the effect of convenient shading and changing the shading degree.

[0058] It should be noted that although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
