Abstract: An air purifying device includes at least one liquid-absorptive filtering core, a sterilizing liquid contained in the filtering core, and a liquid container for supplying the sterilizing liquid to the filtering core. The sterilizing liquid includes a nonionic detergent and a free radical releasing agent. The filtering core includes a porous foam sheet with a high void ratio and a plurality of highly absorptive cotton threads that are uniformly distributed on the foam sheet and that form carriers for the sterilizing liquid. When the air purifying device is mounted in an inlet or upstream side of a mask or an air circulating path of an air conditioner, the hazardous pollutants in the air can be filtered and the bacteria and virus in the air can be killed, thereby purifying the air.

Abstract: An inflatable tent includes a canopy, an inflatable main frame, and at least one inflatable intermediate arcuate support member. The inflatable main frame includes a first inflatable arcuate support member attached to the canopy and a second inflatable arcuate support member attached to the canopy. The first inflatable arcuate support member has a first end located in a first one of four corners of the canopy and a second end located in a second one of the corners of the canopy. The second inflatable arcuate support member has a first end located in a third one of the corners of the canopy and a second end located in a fourth one of the corners of the canopy. The intermediate arcuate support member is attached to the canopy and located between the first inflatable arcuate support member and the second inflatable arcuate support member.
