Background
The sleeping bag is used as a convenient sleeping warm-keeping tool, can be used in the fields of mountain exploration, field operation and the like, can also be applied to outdoor camping and family outing, and plays a vital role in field survival. Currently, the styles of sleeping bags are mainly divided into two types: one is a side-open zipper design, and the other is a center-open zipper design. For cold protection and warm keeping, the sleeping bag is often filled with cotton, wool or synthetic fiber as filler. In the pursuit of lighter, warmer sleeping bags, down-like materials are increasingly used as a filler to fill sleeping bags.
CN 207626957U discloses a novel warm sleeping bag, which comprises a waterproof layer and an inner layer, wherein a down layer and a plurality of gauze linings for dividing the down layer are arranged between the waterproof layer and the inner layer, and the waterproof layer is provided with a zipper for opening and closing the sleeping bag; when the outdoor sleeping bag is used outdoors, the waterproof layer effectively resists the entrance of external cold air and moisture in the air so as to protect the normal use of the sleeping bag, and the down feather layer blocks the exchange of the external cold air and the air in the sleeping bag, thereby improving the heat preservation effect of the sleeping bag.
CN 206565691U discloses a multi-functional eiderdown sleeping bag, including the bag body, eiderdown quilt, block, tighten up the rope, hammock layer, first inflation hole, second inflation hole, netted hammock and fixed rope, the surface side of the bag body is provided with the zip fastener, and its inside arrangement has the eiderdown quilt, and the left end of the bag body is provided with the pillow of connecting the block, and the inside of the bag body is provided with each layer, and this multi-functional eiderdown sleeping bag can be used in comparatively moist environment, but the protection against insects is waterproof, is applicable to various environment.
