Abstract: Disclosed is a high-temperature virus-killing mask, including a sunhat, a heating component and a mask body. A high-temperature microtube with a resistance wire is arranged in the sunhat. The resistance wire may be energized to generate heat to enable the temperature in the high-temperature microtube to rise up to about 200° C., so that, when a user inhales air, the NCP in air flowing through the high-temperature microtube will be killed by the high temperature.

Abstract: An air conditioner having a freezing function includes an external device, an expansion valve, a condenser, a compressor, and an evaporator. The compressor, the condenser, the expansion valve, the external device, and the evaporator are sequentially connected to form a loop. The external device includes a capillary tube and a cut-off valve. The capillary tube is spirally disposed. The cut-off valve is connected in parallel to the capillary tube. A tube coupling is disposed at each of two ends of the capillary tube. The tube couplings are separately fixedly connected to a conduit extending from the expansion valve and a conduit extending from the evaporator. A spiral capillary tube is connected between an expansion valve and an evaporator in an air conditioner, so that the pressure of a liquid refrigerant is reduced when entering the capillary tube, thereby lowering the lowest refrigeration temperature to implement quick cooling.
