Air mattress

Technical Field

The invention relates to the technical field of inflatable products, in particular to an inflatable mattress

Background

The inflatable mattress has strong flexibility and elasticity, and the inflated mattress has the advantages of difficult deformation, comfort and easy carrying, and is popular with people.

Currently, the inflatable mattresses in the market generally have the following defects: firstly, the air permeability is poor, a person sleeps on the mattress for a long time, feels stuffy and uncomfortable, and long-term moisture causes adverse effects on the body health of the person; secondly, the noise is high, when a user lies on the bed and turns over the body, the inflatable mattress can make a sound, and the sleep of the user is influenced; thirdly, the mattress is easy to expand in an irregular shape after being inflated, thereby influencing the use effect.

On the other hand, in order to maintain the inflatable mattress in a desired shape in an inflated state, it is generally necessary to provide drawstrings in the inflation cavity of the inflatable mattress, and conventional inflatable mattresses all use drawstrings that vertically connect a top sheet and a bottom sheet of the inflatable mattress, and after the inflatable mattress is inflated, the drawstrings can generate vertical tension on the top sheet and the bottom sheet. However, the airbed having such a structure has the following disadvantages: firstly, the stress at the joint of the drawstring and the face sheet or the bottom sheet is concentrated, so that the joint of the drawstring and the face sheet or the bottom sheet is easy to break or the face sheet or the bottom sheet is easy to tear; secondly, the bed body is easy to partially collapse or incline upwards and is not stable enough, and the using effect and the service life are influenced.

The present invention is directed to overcoming at least one of the above-mentioned disadvantages of the prior art and providing an air mattress that solves the problems of the air mattress, such as loud noise, poor air permeability, slipping during use, discomfort, and excessive expansion and deformation.

The invention adopts the technical scheme that the inflatable mattress comprises a mattress body which is formed by enclosing a top surface, a bottom surface and side surfaces, wherein the top surface of the mattress body is formed by attaching a flocking layer and a PVC/TPU layer, and the bottom surface and/or the side surfaces of the mattress body are formed by attaching a cloth layer and a PVC/TPU layer.

The flocking layer of the top surface is arranged on the outer side of the PVC/TPU layer, the cloth layer of the bottom surface and/or the side surface is arranged on the outer side of the PVC/TPU layer, and the PVC/TPU layers between the top surface and the side surface and between the bottom surface and the side surface are mutually welded or attached to form a mattress structure.

In this technical scheme, the top surface of mattress body corresponds the one side that the user was lain flat, and the bottom surface corresponds the one side with ground contact, sets up the flocking layer through the top surface at the mattress body, can reduce the noise that PVC material and human friction produced, and at the top surface flocking of mattress body, enables the air mattress more fine and smooth, ventilative, when contacting with human skin, gives other people more comfortable impression to improve the travelling comfort of using.

And the bottom surface and the side of mattress body are laminated by bed of cloth and PVC TPU layer at least one side and are formed, and the bed of cloth can reduce the noise that the mattress produced when being touched, avoids breaking, improves the life of mattress body.

In addition, after the mattress in the prior art is inflated, the mattress body can expand towards the arc shape more, so that the mattress body is protruded in a bread shape, the mattress body is not smooth enough and attractive enough, and the service life is influenced. And the setting up of bed of cloth has restricted the inflation on PVC TPU layer, makes the holistic tensile of mattress body more level and more smooth, pleasing to the eye, realizes the whole difficult technological effect who warp of mattress body, and has improved the hardness of mattress body, makes the travelling comfort of mattress body higher to prevent breaking of mattress body, improve life.

Wherein, preferably, the bottom surface and the side of mattress body are formed by the laminating of bed of cloth and PVC TPU layer, and the bed of cloth can reduce the noise that the mattress produced when being touched, improves its toughness, avoids breaking, improves comfortable effect and the life who uses.

Further, the PVC soft hardness value of the bottom surface of the mattress body is larger than the PVC soft hardness value of the top surface of the mattress body.

Further preferably, the hardness of the PVC on the side surface of the mattress body is consistent with that of the PVC on the bottom surface of the mattress body.

Further, guarantee at least that the bottom surface of mattress body forms for the laminating of bed of cloth and PVC TPU layer, the PVC soft or hard of the top surface structural layer of mattress body is 35 ~ 45PHR, and the PVC soft or hard of the bottom surface structural layer of mattress body is 55 ~ 75 PHR.

In the technical scheme, the structural layers of the top surface and the bottom surface/side surface are different, and the PVC soft hardness value of the top surface structural layer is lower than that of the bottom surface structural layer, namely the flexibility of the top surface is higher, so that the smoothness and the aesthetic property of the mattress body are further kept, the formation of bread-shaped bulges on the surface of the mattress body is avoided, the PVC soft hardness of the PVC/TPU layer on the top surface of the mattress body is adjusted to be between 35 and 45PHR, preferably 40PHR, and the PVC soft hardness and the flexibility of the structural layer of the bottom surface/side surface are better matched and adapted.

The higher the PHR value is, the softer the PVC softness and hardness of the PVC is, the larger the expansion coefficient of the PVC mattress body is, and the larger the flexibility is, so that the PVC mattress is easy to deform; on the contrary, the smaller the expansion coefficient is, the smaller the flexibility is, and the deformation is hard to occur. In order to balance the expansion coefficient and the flexibility of the traditional PVC mattress, the hardness of PVC is generally required to be 50-56 PHR.

Wherein, the parameter PHR represents the part of rubber or resin added in each 100 parts (by mass) of PVC material, and indirectly represents the PVC hardness by indirectly adding the part of the rubber or resin. The PHR value can be measured using a rockwell hardness meter.

In the technical scheme, the flocking layer on the top surface is fiber flocking, and the flexibility of PVC cannot be influenced after the flocking layer is attached to the PVC; and the cloth layer of the bottom surface is integrated with the PVC after being attached because the cloth has small or no elasticity, so that the cloth layer plays a role in binding and limiting the PVC expansion, thereby limiting the expansion and deformation of the mattress body. Wherein, the PVC soft or hard degree of bottom surface laminating is adjusted 55 ~ 75PHR, and further, is adjusted 60 ~ 70PHR, even makes the PVC soft or hard degree of bottom surface laminating softer, also guarantees bottom surface non-deformable, gives other people more comfortable impression when using, more accords with user's demand.

Furthermore, an upper material supplementing four-ply piece is arranged at the joint of the top surface and the side surface of the mattress body, and a lower material supplementing four-ply piece is arranged at the joint of the bottom surface and the side surface of the mattress body.

Among this technical scheme, the mattress body encloses the shape that closes formation cuboid through top surface, side and bottom surface, goes up feed supplement four and closes the piece and locate the mattress body respectively with feed supplement four closes the piece down and encloses the space that closes formation, and goes up feed supplement four and close the piece and be located around top surface and side connection, and feed supplement four closes the piece down and is located the bottom surface and side connection around, constitutes mattress body and goes up the bed edge and lower bed edge. Wherein, the other positions that go to bed along being higher than the top surface can play interception and spacing effect, can effectively avoid the quilt landing, also can avoid the user to slide down from the mattress when sleeping. The setting of lower bed edge has increased the frictional force of mattress and bottom surface, makes the ground of grabbing of mattress body power bigger, grabs ground more steady, has played the antiskid effect and has improved the travelling comfort of using.

In the technical scheme, the PVC/TPU layers of the top surface, the bottom surface and the side surface are all arranged on the inner side, and the flocking layer/fabric layer is arranged on the outer side, so that the noise reduction effect is better. And the top surface and the side surface are connected, and the bottom surface and the side surface are connected through the PVC/TPU layer and the PVC/TPU layer, so that the air tightness and toughness of the joint can be better ensured, and the stability of the mattress is stronger.

Wherein, the mode of butt fusion includes high frequency and hot melt bonding, and the laminating includes sticky laminating or the mode of mould pressing laminating. The top surface, the bottom surface and the side surfaces of the mattress body are connected through hot melting combination or adhesive bonding. And the PVC/TPU and the flocking layer and the PVC/TPU and the fabric layer are formed by gluing, hot melting or die pressing.

Furthermore, the upper feeding four-ply piece and the lower feeding four-ply piece are made of PVC/TPU materials, and PVC/TPU sheets are sequentially welded end to end or attached to form a rectangular shape.

Furthermore, the upper feeding four-in-one sheet and the lower feeding four-in-one sheet are arranged in a space formed by the mattress body in a surrounding mode, the connecting position of the upper feeding four-in-one sheet and the top surface is higher than the connecting position of the upper feeding four-in-one sheet and the side surface, and the connecting position of the lower feeding four-in-one sheet and the bottom surface is lower than the connecting position of the lower feeding four-in-one sheet and the side surface.

The upper material supplementing four-in-one sheet and the lower material supplementing four-in-one sheet are arranged to enable the whole mattress body to be smoother and more stable.

Furthermore, a plurality of drawstrings are arranged in a space enclosed by the side faces, and the drawstrings are respectively connected with the top face and the bottom face of the mattress body.

Wherein, the PVC soft or hard degree of top surface structural layer of this technical scheme is little, and the elasticity is great, and bottom surface or side structural layer is owing to increased the rubberized fabric layer, and the rubberized fabric layer is non-elasticity or elasticity is less, consequently, sets up the stretching strap slope and has adapted to the difference of top surface and bottom surface elasticity better. In order to better adapt to the hardness of the PVC on the top surface of the mattress body, the angle alpha formed by the drawstring and the bottom surface of the mattress body is more than 60 degrees and less than or equal to 90 degrees.

Wherein, this technical scheme's stretching strap draws to one side to not only the stretching strap atress that makes stretching strap top surface and bottom surface staggers, but makes the stretching strap atress not in unified one orientation, and pulls each other through the stretching strap slope, produces the balance that the power of offsetting each other reaches the stress surface, and the stretching strap is from middle progressively to mattress body's head, tail toward outer more and more slope, makes the mattress top surface reach smooth effect after aerifing.

Furthermore, the middle line of the long side of the mattress body is taken as a symmetry axis, and when the drawstrings are even numbers, the drawstrings are symmetrically and obliquely arranged in a space formed by the periphery of the symmetry axis of the mattress body; when the number of the drawstrings is odd, a group of the drawstrings are arranged in the space where the symmetry axis of the mattress body is positioned, the drawstrings are vertical to the bottom surface and the top surface of the mattress body, and the drawstrings except the symmetry axis are symmetrically and obliquely distributed in the space formed by the periphery of the symmetry axis of the mattress body.

Further, the drawstrings are gradually inclined outward from the top surface of the mattress body to the bottom surface of the mattress body.

The stretching strap is from the top surface of mattress body to the bottom surface of mattress body and outwards inclines gradually, and the stretching strap is close to the middle part of mattress body at the position of exerting oneself of mattress body top surface promptly, and the middle part of mattress body is kept away from at the position of exerting oneself of mattress body bottom surface to the stretching strap for mattress body grabs ground more steadily, is difficult for turning on one's side, has more firm and more smooth beneficial effect.

Furthermore, the cloth layer is made of nylon, terylene, polyester-cotton blended fabric, cotton cloth or sandwich mesh cloth.

Furthermore, the drawstring is in a sheet shape or a column shape or an annular structure, the sheet-shaped drawstring is arranged along the inner circumference of the mattress body, and the joint of the top surface/the bottom surface of the mattress body is in a bent shape or a linear design; the drawstrings in a columnar or annular structure are uniformly arranged in the space of the mattress body and are arranged according to a certain pattern or shape.

Wherein, the top/bottom of the drawstring with the sheet structure is in a linear or wave-shaped design, so that the drawstring is more balanced in stress and better in aesthetic property.

The pull belt with the columnar structure is more stable, and the beneficial effects of uniform stress on the top surface and the bottom surface and good attractiveness can be achieved.

Wherein the pull belt with the columnar structure comprises a cylindrical pull belt, an 8-shaped pull belt or a honeycomb pull belt and the like; the drawstring in the technical scheme is not limited to the above structural design, and can also be designed into other design styles, such as a drawstring with an annular structure.
