Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a schematic view of the structure of a mask for collecting the nucleic acid of the new coronavirus in the breath. As shown in FIG. 1, the mask for collecting the nucleic acid of the new coronavirus in the breath includes a mask body 20, an ear band 10, and an adsorption bag 30. The two ear straps 10 are respectively connected to two sides of the mask body 20 and are used for buckling on the back of the ears so as to cover the mask body 20 on the mouth and nose areas of the face. The bag 31 is detachably attached to the mask body 20 and is used for adsorbing the nucleic acid of the new coronavirus in the breath. In some embodiments, the inner side surface (the side facing the oronasal region) of the mask body 20 is provided with a hook and loop fastener, and the absorption bag 30 is attached to the inner side surface of the mask body 20 by the hook and loop fastener. In other embodiments, both ends of the absorbent bag 30 may be inserted into the inner side of the housing 20 to fix the absorbent bag 30.
Fig. 2 is a schematic view of the structure of the adsorption bag 30. As shown in fig. 2, the adsorption bag 30 includes a bag body 31, a filler powder 33, and a silica gel adsorption film 32. Bag 31 is made of a breathable material and has a small pore diameter so that exhaled air can enter bag 31. In some embodiments, the bag 31 is connected to the inner side of the cover 20 by a hook and loop fastener, and in other embodiments, the top side of the bag 31 is open, and two ends of the bag 31 are connected to the cover 20, so that the bag 31 can hold the silica gel adsorption film 32.
