Description

Technical Field

[0001] The utility model relates to the technical field of biological incubators, in particular to a temperature regulating mechanism of a constant temperature incubator. Background Art

[0002] The biological incubator is one of the indispensable laboratory equipment in scientific research and teaching departments such as plants, biology, microorganisms, genetics, viruses, and environmental protection. It is widely used in constant temperature tests, culture tests, environmental experiments, etc., and plays a vital role in scientific research, environmental protection, sewage treatment and other departments.

[0003] The publication number in the existing public technology is: CN220056850U. A temperature regulating mechanism of a constant temperature incubator includes a container box, a glass incubator, and an observation plate; the glass incubator is fixedly installed inside the container box, and the observation plate cover is arranged above the glass incubator. In the utility model, by providing a container box, an annular heating chamber, an electric heating rod, a spoiler pipe, an air duct and a fan, hot air can be blown into the container box, and heat exchange is performed with the glass incubator in the container box to prevent hot air from directly entering the glass incubator and polluting the environment of the glass incubator. By providing four electric heating rods, multiple heat exchange holes and a fan, hot air can be evenly blown to each side wall of the glass incubator, so that the temperature in the glass incubator changes evenly, and the temperature control in the glass incubator is more accurate.

[0004] However, the above patent still has certain disadvantages when in use: heat will be lost in the process of hot air flowing along the air duct and the heat exchange holes, which will cause the temperature rise in the area close to the heat exchange holes to be greater than the temperature in the area far away from the heat exchange holes, thereby causing the overall temperature control to be uneven, and different surfaces of the glass incubator are prone to temperature inconsistencies. Directly adjusting the temperature to the same degree will cause the subsequent temperature to remain uneven, thereby affecting the overall temperature effect and the internal culture effect, and the overall use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-3 As shown, a temperature regulating mechanism of a constant temperature incubator according to an embodiment of the utility model comprises a container 1 and a glass incubator 11, wherein the glass incubator 11 is installed in the middle position inside the container 1, and a plurality of heat insulation boards 12 are fixedly installed around the glass incubator 11, and a plurality of electric heating tubes 8 are evenly installed on one side of the heat insulation board 12 and located on the inner surface of the container 1, and a plurality of guide plates 9 are symmetrically and obliquely installed on both sides of the electric heating tube 8, and a plurality of airflow heads 13 are evenly installed on the surface of the guide plate 9, one end of the airflow head 13 passes through one side of the container 1 and is connected to the guide pipe 6, one end of the guide pipe 6 is connected to the solenoid valve 5, and one end of the solenoid valve 5 is connected to the airflow box 3, and two groups of airflow boxes 3 are provided in total, and the two groups of airflow boxes 3 are respectively installed on the surface positions on both sides of the container 1, and a plurality of blowers 4 and exhaust fans 14 are respectively installed on the surface positions of the airflow boxes 3, and temperature sensors 10 are installed on the inner surface positions of the glass incubator 11, and the temperature sensor 10 is a common temperature detection device, so it will not be described in detail.

[0029] In one embodiment, a sealing cover 2 is rotatably connected to one side of the top of the container 1. The sealing cover 2 is used to seal the glass culture box 11 during culture to prevent the intrusion of external impurities.

[0030] In one embodiment, a plurality of groups of supporting legs 7 are symmetrically installed on both sides of the bottom of the container 1, and the entire device can be fixed by the supporting legs 7, so as to enhance the overall stability in use.

[0031] In one embodiment, a sealing gasket is installed around the surface of the sealing cover 2. The sealing gasket is provided to improve the overall sealing during culture and avoid interference from external impurities.

[0032] In one embodiment, a controller is installed on the surface of one side of the container 1, and the controller is electrically connected to the solenoid valve 5 and the electric heating tube 8. The controller is a common control device, so it is not described in detail. The electric heating tube 8 is connected and used in a single group and a single line, so that each electric heating tube 8 can be used independently, which is convenient for subsequent temperature control operations.

[0033] In one embodiment, the airflow head 13 is connected to the exhaust fan 14 and the blower 4 at intervals, and the airflow head 13 is arranged to enable the exhaust fan 14 and the blower 4 to control the internal airflow.

[0034] In one embodiment, a filter is provided inside the airflow box 3, and the filter is provided to filter and remove impurities from the flowing gas to prevent impurities from entering and adhering to the electric heating tube 8 to affect the subsequent heat generation operation.

[0035] Working principle: In actual use, personnel can place the items to be cultured into the glass incubator 11 for cultivation, and then the temperature of the corresponding surface can be detected by the temperature sensor 10 at each surface position. When the temperature is detected to be below the preset range, the operation of the electric heating tube 8 at the designated position can generate heat, and the blower 4 can continuously introduce gas into the interior. At this time, the gas contacts the electric heating tube 8 to transport the hot gas to the corresponding surface position, thereby achieving the heating operation of the glass incubator 11. Since the temperatures of different surfaces are different, the electric heating tube at the corresponding position can be controlled by an external controller according to the difference between the detected temperature and the preset temperature. 8 and the opening degree of the corresponding solenoid valve 5 are controlled, so that the amount of gas introduced therein changes, so that the temperature change at different positions can be adjusted accordingly, so that multiple surfaces can evenly reach the preset range, avoiding local overheating or insufficient temperature affecting the overall culture effect. At the same time, a heat insulation board 12 is provided between each surface for separation, so that the interference of each other's temperature can be effectively avoided, ensuring the overall use effect. Similarly, when the temperature is too high, the internal hot air can be extracted by the exhaust fan 14, thereby realizing the corresponding cooling operation. The device can effectively realize the temperature regulation operation by adjusting the temperature increase and decrease. The device as a whole has the advantages of uniform temperature control, independent temperature control and little mutual interference.
