According to an embodiment of the present invention, a liquid nitrogen cold trap is provided, fig. 1 is a schematic structural diagram of a liquid nitrogen cold trap provided according to an embodiment of the present invention, as shown in fig. 1, the liquid nitrogen cold trap 10 is integrated with a cold trap cleaning device 12, and the cold trap cleaning device 12 includes: a hollow container 122 and a heater 124, wherein the hollow container 122 is used for placing a liquid nitrogen cold trap; and the heater 124 is used for blowing hot air into the hollow container with the liquid nitrogen cold trap, and collecting the hot air through the hollow container to heat the liquid nitrogen cold trap. The heater may include various kinds, for example, a heat gun, etc.
In the embodiment of the invention, the clear cold trap device is integrated on the liquid nitrogen cold trap, hot air is blown into the hollow container with the liquid nitrogen cold trap by the hot air blower, and the liquid nitrogen cold trap is heated by the hot air collected by the hollow container, so that the aim of heating the liquid nitrogen cold trap by the collected hot air is achieved, the technical effect of greatly improving the efficiency of the clear liquid nitrogen cold trap is achieved, and the technical problem of low efficiency of the clear cold trap caused by the fact that the cold trap needs to be continuously heated for a long time in the process of clearing the cold trap in the related technology is solved.

When the liquid nitrogen cold trap needs to be cleaned, the liquid nitrogen cold trap is taken out from the dilution refrigerator and is put into a cold trap cleaning device arranged outside the dilution refrigerator for cleaning. It should be noted that the liquid nitrogen cold trap may be movably disposed in the dilution refrigerator in various manners, for example, the liquid nitrogen cold trap may be movably disposed in the dilution refrigerator by connecting the liquid nitrogen cold trap to the dilution refrigerator through a buckle, or movably disposed in the dilution refrigerator by suspending the liquid nitrogen cold trap in the dilution refrigerator.
For another example, the direct integration of the liquid nitrogen cold trap and the cold trap device includes: the clear cold trap device wraps the liquid nitrogen cold trap and is fixedly connected.
