Shock absorption air changing mattress cushion

Abstract

The present invention discloses one kind of damping and scavenging mattress and cushion, each of which includes one upper cushion body, one lower cushion body, one outer cover and one inner cover set between the upper cushion body and the lower cushion body, elastic pieces supporting the outer cover and the inner cover, and locating blocks for locating the elastic pieces inside the outer cover and the inner cover. The elastic piece has at least one inner spring set coaxially with the outer cover and the inner cover; and the outer cover or the inner cover is provided with scavenge ports and non-return leaf valves inside the scavenge ports. The damping and scavenging mattress and cushion have easy assembling and disassembling, adjustable bearing force and good damping and scavenging effect.

Description

technical field [0001] The invention relates to a cushion for a mattress, in particular to a cushion for a shock-absorbing and ventilating mattress. Background technique [0002] At present, there are three main structures of spring mattress cushions on the market: (1) The outer layer of the cushion body is stitched by decorative fabrics, and the outer layer is covered with hundreds of compression springs connected in series by vertical and horizontal spiral steel wires. Spring; (2) The cushion body is made of hundreds of cloth bags that are stitched together in series or bonded with hot melt adhesive to form a bed net, and a coil spring is placed in each cloth bag; (3) The foam sheet is used as the bed The pad is provided with a through hole in the pad body to place a spring to enhance its supporting force. The above-mentioned three kinds of mattress cushions have the following deficiencies in actual use: (1) their cushion bodies are sealed, bonded or foamed sheet entities...

AI Technical Summary

Problems solved by technology

The above-mentioned three kinds of mattress cushions have the following deficiencies in actual use: (1) their cushion bodies are sealed, bonded or foamed sheet entities, and more importantly, their springs are all covered by steel wires. One-piece connection, or fixed on the cushion body, so that the cushion body and the spring are firmly connected as one. When the spring needs maintenance, the disassembly and assembly of the cushion body is very troublesome or even impossible to disassemble, resulting in the mattress seat being unable to be repaired and then discarded or Replacement; (2) Because hundreds of springs in the mattress cushion are either firmly connected with steel wires or fixedly connected with the cushion body, people cannot change the spring support force of the cushion body to adapt to the weight requirements of different users , when the weight of the user is large, or the cushion is used for a long time, it is easy to be partially crushed or tilted and deformed; (3) the cushion is sealed, stitched, glued or foamed, and there is no active replacement Occasionally, only a few holes are set around the cover of the mattress as passive air convection holes, and the humidity, temperature, and human body odor inside the covered mattress are difficult to release out; (4 ) Due to the lack of a perfect ventilation system inside the pad body, it is difficult to clean the internal stains, stagnation, etc. Dust, dander and horny matter from human skin have become food for mites and a breeding ground for bacteria, which does not meet the requirements of cleanliness and hygiene

However, in the actual use process, the protective tube described in this patent has the following disadvantages: ①The pad body, elastic body and protective tube are all fixed designs, and the position of the protective tube cannot be changed at will; ②The built-in spring of the protective tube is a , only one elastic modulus of supporting force can be produced, and the user cannot change the spring supporting force of the mattress according to the weight; ③ There is no air exchange function, and dust and debris are easy to accumulate in the mattress body, and the sanitary conditions are not good

The following disadvantages also exist in the actual use of this patented product: ①The non-woven bag spring strings of the "spring in spring" structure of the bed net and the bag spring string and the bed net mask are bonded together by hot melt adhesive. As a whole, when the spring blank is damaged, it is difficult to disassemble and assemble the pad body, and maintenance is troublesome; ②The user cannot adjust the elastic supporting force of the "spring in spring" at will according to the variation of the user's weight; ③The "spring in spring" of the bed net The structure has no positive air replacement function, and the net bed is also easy to accumulate dust and debris
