Description
Technical Field
The invention relates to the technical field of mattresses, in particular to a self-adaptive adjusting mattress.
Background
Magnetism is one of the properties of a substance. Both the magnetic substance and the magnetic field have a certain effect on the physiological functions of the organism, which is called the magnetic effect of the organism. This magnetic effect is determined by the electronic movement of the microstructure inside the object and the magnetism of the substances constituting the biological tissue. In recent years, with the development of modern magnetism and biology, edge science of biomagnetism has emerged, and scientific experiments have confirmed that magnetic substances and magnetic fields exhibit different effects on various levels of molecules, cells, nerves, organs and the whole body (referred to as living body) of organisms. The human body also has certain magnetism, and it has been found that the current activity of the human brain, heart, skin and other organs all generate magnetic fields, and even hair follicles on the connecting hairs also generate magnetic fields.
The magnetic therapy is to use the biological magnetic effect inside the human body to adjust and recover various unbalanced or abnormal functional states in the human body so as to achieve the purpose of health care. According to the biological magnetic effect, the magnetic therapy treatment mechanism can be summarized as the following aspects: 1. the redox reaction, nerve conduction, cardiopulmonary beating, etc. during life are all related to the electron transfer inside the human body, and the magnetic field can affect the movement of electrons. 2. The biological membrane has extremely strong permeability selectivity and has main effects on brain potential in the human body and exchange and metabolism of substances. Magnetic fields can affect the permeability of some charged ions, such as potassium, sodium, oxygen, and the like. 3. Various enzymes and proteins in the human body contain many trace transition metals such as iron, cobalt, manganese, copper, etc. These trace elements are mostly components of various enzymes and proteins, and are also the active centers of enzymes and proteins. The magnetic field changes the activity of the enzyme and protein by the action of transition metal elements (magnetic ions), and accelerates the biochemical reaction of the enzyme system. The balance of organism electromagnetism is adjusted through magnetic therapy, and the specific effects on the organism comprise: the permeability of cell membranes can be increased, blood vessels can be expanded, blood circulation can be expanded, and the blood circulation is accelerated, so that the effects of relieving swelling and pain can be achieved; ② the medicine has the functions of diminishing inflammation and relieving pain by influencing physiological and biochemical reactions of tissues; thirdly, the central nervous function excitation is inhibited, the sleep state is improved, the sleep time is prolonged, the muscle spasm is relieved, and the blood pressure is reduced to play a role of sedation; the high-intensity magnetic field can inhibit the growth and the metastasis of certain cancers; low intensity magnetic field, delaying aging process, etc.
The magnetic therapy mattress is a magnetic therapy sleeping system product which can exert magnetic therapy function on human body in the sleeping process. In the prior art, a magnetic mattress is provided with a plurality of magnetic elements for generating a magnetic field, such as hundreds of permanent magnets, which are arranged according to a certain rule. When lying on the magnetic mattress, the magnetic blocks can comfortably and uniformly contact the whole body of a person to generate a magnetic field, so that the magnetic mattress can promote blood circulation, is beneficial to human health and improves sleeping quality.
However, the magnetic strength generated by the magnetic elements in the magnetic therapy mattress in the prior art is fixed, and the magnetic therapy effect exerted by the magnetic therapy mattress on the human body is also fixed. However, as is well known, the functions of the human body to be treated by the magnetic therapy are obviously different among individuals, and the magnetic therapy effect required by each human body and even different parts of one human body may be different, so that the magnetic therapy effect of the magnetic therapy mattress in the prior art on different human bodies is greatly different.
In order to overcome the above technical defects, researchers have proposed coating an organic magnetic material layer on the surface of the magnetic element of the magnetic therapy mattress. However, the ferromagnetism of organic magnetic materials is significantly affected by temperature, and generally has ferromagnetism only at low temperature, thereby limiting the application of the magnetic therapy mattress.
