Temperature-adjustable thermostatic pad warm in winter and cool in summer

Abstract

The invention discloses a temperature-adjustable thermostatic pad warm in winter and cool in summer. The thermostatic pad comprises a substrate and a temperature adjusting pad, wherein the temperature adjusting pad is a grooved three-dimensional fabric; one or more uniformly arranged grooves are formed in the bottom of the temperature adjusting pad; phase change material bags are placed in the grooves, and are sealed and packaged by adopting a high-strength flexible material; heating units are arranged at the bottoms of the phase change material bags. According to the thermostatic pad, a phase change material can change between a high-energy state and a low-energy state in the presence of the heating units and an air conditioner, so that the micro-climatic environment around a human body can be kept within a relatively constant and proper temperature range in different environments through the thermostatic pad, the requirement of the human body on comfort is met, and the thermostatic pad has warm keeping and cooling functions; necessary elasticity and support force are provided by a high-bending rigidity fiber layer of the raised part in the three-dimensional fabric, so that good pressure spreading effects are achieved, and the phase change material bags in the grooves can be protected; sufficient pores are formed in the raised part of the grooved three-dimensional fabric, so that high air permeability is ensured.

Description

Technical field [0001] The invention belongs to the technical field of production and manufacture of life pads or medical pads, and specifically relates to a thermostatic pad that is warm in winter and cool in summer. Background technique [0002] As the global climate warms, summer temperatures in most parts of my country are gradually higher than before, which has clearly exceeded the human body temperature; winter temperatures are still low, especially in Jiangnan and other places with high humidity and low body temperature. The quality of sleep, the warmth and cooling of mattresses have always been hot issues of concern. [0003] At present, the most common way to heat the bed in winter is to use electric blankets. The problem with electric blanket heating is that it is not safe to use when it is powered on, and electromagnetic radiation may cause potential hazards to the human body; when it is powered off, users often increase the temperature and heat the bedding, and the huma...

AI Technical Summary

Problems solved by technology

The problem with electric blanket heating is that it is unsafe to use with power on, and at the same time, electromagnetic radiation may cause potential harm to the human body; Because the temperature is higher than the comfortable temperature of the human body, it will feel hot and dry during sleep, and after the heat stored in the bedding is dissipated, the human body will feel cold again.

The problem with these patents is that the power cannot be cut off, and it needs to be used with electricity during use, and the temperature cannot be kept constant after the power is cut off.

The problem with this technology is that the energy storage of energy storage materials requires the help of external energy, and the patent does not provide external energy as a means of supplementing the heat of energy storage materials

The problem is that when used as a mattress, 1) the phase change material package has no protection, and the human body is directly pressed against the material package. When the phase change material turns into a liquid, the phase change material package may burst under pressure; 2) ) The cool pad is a one-way temperature adjustment, which can only be used in summer and cannot be used in winter; 3) The watertight material is impervious to vapor and moisture, and the sweat vapor generated by the human body during sleep cannot be removed in time. Although it cools down, it will cause human body Accumulation of moisture on the surface, causing discomfort
