Description

Technical Field

[0001] The invention relates to the technical field of biological cultivation, in particular to a biological cultivation device for biological experiments. Background Art

[0002] With the development of society, biological science research has continued to deepen in many fields, and biological culture devices have become indispensable experimental tools. In the process of biological culture, temperature is an extremely critical factor. Different biological samples, such as microorganisms, cells, tissues, etc., have their specific suitable growth temperature range. For example, some bacteria grow and reproduce most vigorously in an environment of about 37°C, while some plant cell cultures may require a constant temperature of about 25°C. Accurately controlling the temperature in the culture device can provide a stable growth environment for biological samples and ensure the accuracy and reliability of experimental results. If the temperature is too high or too low, it may affect the metabolic activity and growth rate of the biological sample and even cause the sample to die, causing the experiment to fail and wasting a lot of manpower, material resources and time resources.

[0003] However, existing biological culture devices have obvious defects and cannot automatically control the temperature. During the experiment, the operator needs to manually monitor the temperature frequently and make adjustments. This not only increases the workload of the operator, but also makes it difficult to ensure the timeliness and accuracy of temperature control. Due to the inability to respond to temperature changes in time, the temperature in the culture device may deviate from the appropriate range for a long time, causing irreversible damage to the biological samples. At the same time, the instability of manual operation will also introduce human errors, affect the repeatability and comparability of the experiment, and is not conducive to the accuracy and standardization of biological science research.

[0031] A water inlet 601 is provided at the top of the outer wall of the water tank 6, and the water inlet 601 is convenient for injecting water into the water tank 6. A drain outlet 602 is provided at the bottom of the outer wall of the water tank 6, and the drain outlet 602 is used to discharge the water in the water tank 6. Plugs are fixedly installed inside the water inlet 601 and the drain outlet 602, and the plugs ensure the sealing of the water inlet 601 and the drain outlet 602 during normal use.

[0032] A plurality of first slots 401 are provided inside the placement table 4, and the first slots 401 enable steam to circulate better around the placement table 4 to improve temperature uniformity. Two second slots 501 are provided inside the mounting plate 5, and the mounting frame 8 is located inside the second slots 501, and the second slots 501 provide installation space for the mounting frame 8.

[0033] The bottom of the housing 1 is fixedly connected with supporting feet 20. There are four supporting feet 20 distributed in a rectangular shape. The supporting feet 20 can place the device stably on the experimental table. The bottom of the supporting feet 20 is made of rubber material and has certain anti-slip properties.

[0034] Working principle: When in use, place the culture vessel on the top of the placement table 4, then inject pure water into the water tank 6 through the water inlet 601, and then turn on the heating wire 7 to heat the pure water inside the water tank 6 and generate steam. At this time, the inside of the shell 1 is at room temperature, which will not affect the shape change of the iron sheet 906 and the copper sheet 907, so the first block 909 will not be located inside the exhaust pipe 901. The steam generated inside the water tank 6 can enter the top of the support plate 3 through the exhaust pipe 901, and the temperature of the steam assists the biological culture.

[0035] During use, if the temperature inside the shell 1 is too high, the iron sheet 906 and the copper sheet 907 will be deformed. Because copper expands faster than iron when heated, this uneven expansion will cause the bimetallic strip to bend and deform, bending toward the side of the iron sheet 906. At this time, in order to cooperate with the bending of the iron sheet 906 and the copper sheet 907, the second mounting block 905 will slide downward, and the first mounting block 904 will slide toward the exhaust pipe 901, while driving the first stopper 909 to block the exhaust pipe 901, so that the steam inside the water tank 6 cannot enter the top of the sealing cover 2. When the temperature inside the shell 1 drops, the iron sheet 906 and the copper sheet 907 will return to the straight state, and the first stopper 909 will no longer block the exhaust pipe 901. In the above process, two sets of temperature control components 9 are used to achieve precise temperature control of the two ends of the shell 1.

[0036] Furthermore, if the pressure inside the shell 1 is high due to steam during use, the steam will push the second baffle 14 upward, allowing the shell 1 to connect with the outside world and release the steam. After the pressure inside the shell 1 stabilizes, the spring 13 pushes the second baffle 14 downward, so that the inside of the shell 1 returns to a sealed state.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
