Description

TECHNICAL FIELD

[0001] The utility model relates to centrifuge structure technical field, concretely relates to a kind of heating centrifuge structure with efficient temperature control. BACKGROUND

[0002] When centrifuging solution, centrifuge is needed, and the main technical parameters of the centrifuge include rotation speed, capacity, temperature control range and centrifugation time. During the operation of the centrifuge, the change of the temperature of the substance will affect the solubility and reaction rate of the substance in the sample, thereby affecting the separation effect. Therefore, temperature control is crucial for maintaining the state of the sample and ensuring the accuracy of the centrifugation result. In the traditional centrifuge structure, a container made of heat-insulating material is generally used to hold the solution sample, but the temperature of the sample will still decrease over time. The heat-insulating effect of the container is limited, and it can only slow down the rate of temperature decrease of the sample, but it cannot maintain the temperature of the sample. When the temperature of the sample decreases to a certain extent, it will directly affect the result of the operation of the centrifuge.

[0003] It can be seen that the current centrifuge device still needs to be improved, and it should be optimized to maintain the temperature of the sample and control the temperature of the sample, so as to improve the effect of the operation of the centrifuge. Therefore, a more reasonable technical solution is needed to solve the technical problems existing in the prior art. SUMMARY

[0004] To overcome at least one of the above-mentioned defects, the utility model provides a heating centrifuge structure with efficient temperature control, which actively controls the temperature of the container to maintain the temperature of the sample inside, so as to ensure that the sample maintains a suitable state for centrifugation during the centrifugation process, and the result of the entire centrifugation is stable and reliable.

A centrifugal motor is also arranged in the main shell, the rotating shaft of the centrifugal motor penetrates the inner container, the rotating shaft extends from the shaft hole of the heat insulation plate to the top of the inner container, and a heat insulation sleeve is also arranged on the rotating shaft.

[0007] The centrifuge structure disclosed above has the double structure formed by the outer barrel and the inner barrel, has the heat insulation effect, and is provided with the heating assembly in the interval cavity, so that the temperature of the inner barrel can be maintained by active heating, thereby maintaining the temperature of the sample in the inner barrel; the centrifugal motor is used for providing the centrifugal driving force, the heat insulation plate and the heat insulation sleeve cooperatively arranged at the rotating shaft of the centrifugal motor are used for protecting the bearing on the rotating shaft, and the situation that the heat is transmitted from the rotating shaft to the bearing to cause the temperature to be too high can be avoided.

[0008] Further, when the centrifuge is operated, the temperature in the inner barrel needs to be effectively controlled, and therefore the temperature feedback can help better control the temperature.

When the above scheme is adopted, the annular shell cavities form a concentric structure from the inner surface of the cover body, and the heat insulation effect can be improved after the shell cavities are filled with the heat insulation materials.

[0011] Further, the heating assembly is used for heating the inner barrel to maintain the temperature of the sample in the inner barrel, and the structure thereof is not uniquely limited.

When the above scheme is adopted, the heating plate can be attached to multiple positions on the outer part of the inner barrel, including the side surface and the bottom surface. The number of heating plates can also be set to be single or multiple. When the number of heating plates is multiple, the heating plates are uniformly and spacedly arranged.

[0012] Further, the heating plate can also adopt various designs, and the structure is not uniquely limited, and one of the feasible options is optimized and proposed herein: the heating plate comprises a disc-shaped heating disc, and the heating disc is attached to the bottom surface of the inner container. When the above scheme is adopted, the heating disc can be provided as a circular disc.

When the above scheme is adopted, the heat insulation material can be a flexible material, such as heat insulation cotton.

[0014] Further, when the temperature of the inner container or the centrifugal motor is too high, cooling is needed to maintain a suitable temperature, which can be achieved in various ways, and one of the feasible options is optimized and proposed herein: the main shell is formed with a heat dissipation structure.

When the above scheme is adopted, air flow is formed inside and outside the main shell to exchange heat.

[0016] Further, the heat dissipation structure can also be optimized: the heat dissipation structure comprises a heat dissipation fan provided in the main shell. When the above scheme is adopted, the heat dissipation fan is used to promote air circulation inside and outside the main shell to promote heat exchange.
