Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

as shown in fig. 1 and 2, the double-layered massage mattress of the present embodiment comprises an outer cover 8 and a massage mattress 1 wrapped in the outer cover 8, wherein the massage mattress 1 comprises a top layer 11, a bottom layer 12 and massage beads 13 uniformly laid between the top layer 11 and the bottom layer 12 from top to bottom, and the massage beads 13 move between the top layer 11 and the bottom layer 12 under the pressure from the top layer 11.

When the massage mattress 1 is used, because the massage beads 13 are not limited in degree of freedom, the massage beads 13 can make corresponding displacement between the top layer 11 and the bottom layer 12 under the action of human body, for example, when a user lies on the massage mattress 1 flatly, the back and the hip are the force points when the human body is in a natural state, the waist is relatively upward and is not contacted with the massage mattress 1, the massage beads 13 move to the waist more relatively and are stacked on the waist, so that the whole human body is under the action of the massage beads 13, and all-round massage is realized; the user lies on his side and the massage beads 13 will be displaced relatively more in the direction away from the human body.

In the specific embodiments provided by the present disclosure, the massage beads 13 may be configured in any suitable configuration. Alternatively, the massage beads 13 are wooden beads. The size of the massage beads 13 depends on the specific conditions and requirements of the user, and in case of a thin user, a small thickness of the top layer 11 or other situations, the size of the massage beads 13 is relatively small to avoid that the massage beads 13 are too irritating to the user; in case of a fat user, a thicker top layer 11 or other situations, the size of the massage beads 13 is larger to ensure that the massage beads 13 perform a massage function.

The wood beads are made of fragrant wood, so that the massage effect is achieved, and meanwhile, the fragrance of the wood relieves the nerves of a human body, and deep sleep is facilitated; meanwhile, the wood for manufacturing the wooden beads adopts the roots of the felled trees, so that waste is changed into valuable, and the forest is protected; the wood used is wood such as Phoebe serrulata, Phoebe chinensis, Cinnamomum camphora, etc.

In the specific embodiments provided by the present disclosure, massage mattress 1 may be configured in any suitable configuration. Alternatively, the top layer 11 has a thickness less than the thickness of the bottom layer 12; the top layer 11 is made of natural latex and the bottom layer 12 is made of sponge. Latex (latex) generally refers to a colloidal emulsion of polymer particles dispersed in water, and is also called latex. Latex can be classified into natural, synthetic and artificial 3 types. The natural latex is a liquid flowing out from a rubber tree with a certain age when tapping according to a specified cut at a specified time, is milk white, has a solid content of 30-40 percent, and has an average rubber particle size of 1.06 micrometers. The fresh natural latex contains 27-41.3 wt% of rubber component, 44-70 wt% of water, 0.2-4.5 wt% of protein, 2-5 wt% of natural resin, 0.36-4.2 wt% of saccharide and 0.4 wt% of ash. In order to prevent the natural latex from coagulating due to the action of microorganisms and enzymes, ammonia and other stabilizers are often added. Natural latex is mainly used for making sponge products, extruded products and dipped products. Synthetic latexes are typically made by emulsion polymerization, such as polybutadiene latex, styrene-butadiene latex, and the like. To achieve a solids content of 40% to 70%, the rubber particles are first agglomerated into larger particles and then concentrated in a similar manner to natural latex. The artificial latex is a rubber latex which is not emulsion-polymerized. Adding water and surfactant into the colloid generated by solution polymerization to disperse the rubber particles in water, and evaporating to remove the solvent.

Most of the existing sponge mattresses are slow rebound sponge mattresses. The slow rebound sponge mattress has good rebound characteristics, greatly reduces the necessity of turning over on the bed, and further improves the sleep quality of people. The slow rebound memory sponge is different from the traditional sponge in that: slow rebound memory sponges are a special material that is different from any sponge that has been previously contacted. The slow rebound memory sponge is a material which can still deform according to the temperature change of the body. When the slow rebound surface is stressed it does not produce a rebound force until all the pressure is evenly distributed. When the external force extrusion stops, the external force extrusion can slowly recover the original shape.

The mattress made of natural latex has the advantages of mite and bacteria prevention and ventilation, but the price is relatively high, so the massage mattress 1 can also be made of other materials, such as bamboo fiber, springs, palm and the like.
