Description

Heat-storage warm sleeping bag

Technical Field

The utility model belongs to the technical field of outdoor articles for use and specifically relates to a heat accumulation sleeping bag that keeps warm.

Background

The sleeping bag is a bag-shaped object used for outdoor sleeping, is widely applied to the civil and military fields, is a necessary article for expeditioners, mountaineers and soldiers, and provides a good sleeping space for people when people have an outdoor rest.

With the continuous emergence of new materials and the increasing improvement of the living standard of people, outdoor sleeping bags no longer seek single heat preservation performance, but have higher requirements on the aspects of comfort, functionality and the like.

According to the analysis of the heat storage and heat preservation energy sources of the materials used by the sleeping bag, the heat preservation and heat storage modes used by the traditional sleeping bag are divided into two modes of using passive warm-keeping materials and using active warm-keeping materials.

The positive warm-keeping mode refers to actively obtaining heat from the outside to raise the temperature so as to offset or slow down the heat loss and achieve the effect of keeping warm. Generally, two heating ways of external electric heating and sunlight (far infrared conversion) are adopted. The electric heating temperature-rising heat-storage sleeping bag generally adopts an external battery heating mode to heat, the circuit safety can not be completely reliable in a humid environment, and in a low-temperature severe cold area, the discharge voltage of the battery is greatly reduced along with the reduction of the external temperature, so that the battery can reach the discharge cut-off voltage more quickly during low-temperature discharge, and the low-temperature discharge capacity is obviously lower than the normal-temperature capacity, namely, the electric quantity is insufficient. When the environmental temperature is lower, the discharge capacity of the battery rapidly attenuates along with the temperature reduction, when the discharge temperature of the battery is-10 ℃, the 2C rate discharge capacity of the battery attenuates by 50 percent, and once the temperature is lower than-15 ℃, the 2C rate discharge capacity attenuates by nearly 80 percent (Zhang Yu, Lu Sho, Wei Li Chuan, et al. basic experiment research on the correlation between the performance of the lithium battery and the temperature [ J ]. Sian university of transportation, 2018, v.52(05): 138-.

The sunlight (far infrared heating) heat storage sleeping bag adopts the principle that far infrared rays in the spectrum of sunlight can be absorbed and converted into heat energy to be supplied to the sleeping bag for heating (Zhanglian force, Yang Meng, Zhai Bao, Beijing architecture university, a solar heating tent and phase change heat storage sleeping bag cooperative system, publication No. CN109057513A, published time: 2018.12.21), but has large limitation, and sufficient far infrared rays cannot be obtained in cloudy and rainy days and at night, so that the limitation is large during actual use.

Passive warming means that warming is achieved by reducing or preventing the way heat is dissipated. In this way, the filler is made of animal down, cotton, common chemical fiber wadding and other materials. These materials are easy to be agglomerated when being washed and dried, and cannot keep fluffy when being pressed by human body during sleeping, thus affecting the using effect (left fragrant, expert unscrambles down garment warmth retention and detection [ J ] Chinese fiber inspection, 2019(02): 57-59.). According to the research, the warm-keeping effect of the sleeping bag mainly comes from a cavity formed by interweaving and staggering fillers, the cavity can store a large amount of air, the air has a certain heat insulation effect, so that heat inside the sleeping bag is not easy to lose, and once the fillers are agglomerated or compressed, the air capable of being stored inside the sleeping bag is greatly reduced, and the warm-keeping effect is seriously influenced (yellow jade, Shangdong, Schui Yes. Down jackets for warm-keeping discussion [ J ] Proc. Wuhan science and technology college, 2007,20(1): 25-29.).

In the case of the bottom material of a sleeping bag, the bottom layer of a conventional sleeping bag is in direct contact with the ground, and the internal structural space of the sleeping bag is completely compressed by the human body, so that air cannot be stored. The insulation of air is lost among the human body, the sleeping bag filler and the ground, and the human body heat is directly conducted to the ground through the down feather, the wadding sheets and the fabric at the bottom layer of the sleeping bag, so that the internal temperature of the sleeping bag is rapidly lost, effective warm keeping can not be achieved, and the comfort level is greatly reduced.

In conclusion, how to improve the heat storage and warm keeping effects of the sleeping bag and slow down the heat conduction is a problem to be solved urgently at present.
