Description

Full bamboo function bed of adjustable soft or hard degree

Technical Field

The invention relates to the technical field of life bed tools, in particular to a full bamboo functional bed with adjustable hardness.

Background

The sleep quality has important influence on the emotion, the work efficiency, the life quality, the social interaction and the like of people, the sleep disorder problem is more and more prominent along with the acceleration of the life rhythm and the change of the life style of modern people, the investigation shows that the average sleep time of residents in China is less than 6.8 hours, 55 percent of people are deeply interfered by the sleep problem, the bed is used as an important carrier of sleep and has a close relation with the sleep condition of people, and the research shows that 7 percent of the sleep disorder problem is related to the support performance of the bed. On one hand, in the sleeping process, the gravity of the human body acts on the bed, so that a certain supporting force can be generated on the surface of the bed, and if the bed does not have a good pressure relieving effect on the human body, the over-concentrated pressure distribution can cause the ischemia phenomenon of local muscle soft tissues of the human body, so that the tissues are irreversibly damaged; on the other hand, if the bed is not sufficiently supported by the human body, the spine of the human body is in an unnatural bent state, which is likely to cause pathological changes in the spine and fatigue of muscles. Therefore, the scientific and reasonable bed design should ensure that the supporting force of the head, the shoulders, the waist, the buttocks, the legs and other areas of the bed surface is matched with the weight distribution of the human body, the shape of the indentation of the human-bed interface is matched with the external dimension of the human body and the musculoskeletal system, and only then, the sleep-posture spine is ensured to be in a natural bending state, and the reasonable pressure distribution of the human-bed interface is ensured. The bed in the market at present mostly presents consumers with the fixed hardness of bed surface is whole, can't provide corresponding holding power to each position of the crowd of different sizes, weight like this, in addition, the bed relies on the hardness subregion design to the mattress to realize the support to each position of human body, so, a section mattress can only satisfy the user demand of a small part of people, can't change and the sleep hobby according to consumer's size, and adjust by oneself to the hardness on bed surface, can't really freely realize the accurate matching between people-the bed promptly, and the mattress subregion design on the market is various, often the subregion design of mattress and the hardness that sets up is unscientific, unreasonable phenomenon.

At present, the manufacturing materials of the bedding on the market are mainly concentrated on wood and metal, and solid wood beds, iron beds, steel beds and the like have high hardness, so that the sleeping comfort is seriously influenced after long-term use, and the protection of the spine and the pressure relief of a human body are not facilitated. In addition, metal is a high-energy-consumption product, environment pollution is easily caused in the production process, the development of low-carbon environment-friendly economy is not facilitated, environment-friendly furniture is more and more popular with consumers along with the enhancement of health and environment-friendly consciousness of people, wood is a low-carbon environment-friendly renewable ecological material, but the resource condition is not optimistic, China is a second big wood consuming country and a first big wood importing country in the world, the total wood consumption amount of China is increased by 173% in recent 10 years, 6 hundred million cubic meters of wood consumption are consumed in the whole country at present, the external dependence degree exceeds 55%, therefore, nowadays, wood resources are increasingly deficient, environment-friendly call is higher, and the use of a high-quality ecological material with a short growth cycle to replace other wood species is urgent. The bamboo wood is a natural plant material which is easy to reproduce, fast to grow, early in lumber formation and high in yield, is successfully forested once, can be selectively cut every year, is the country with the most abundant bamboo resources, the largest bamboo forest area and the most bamboo yield in the world, has the advantages that the bamboo yield accounts for 1/3 of the total world yield, the bamboo forest area, the bamboo forest accumulation amount, the bamboo variety and the bamboo product yield are all in the first place of the world, and the bamboo wood has the excellent advantages of high strength, good elasticity, high toughness, low heat conductivity coefficient, stable performance, higher specific strength and specific rigidity than wood, common steel and the like. Therefore, in conclusion, the bamboo wood is a renewable ecological material with excellent mechanical property and environmental protection property, and is very suitable for being used as a manufacturing material of the bed.
