For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The inflatable bed in the prior art has an inflation cavity. When used after being inflated, the inflatable bed has poor stability and is prone to tilt or sag at a local position, resulting in a poor user experience.

[0034] In view of this, the designer designed an inflatable bed with at least two independent chambers, one of which is the main chamber and the other is an auxiliary chamber. The auxiliary chamber is arranged around the main chamber and can enhance the stability of the edge of the main chamber. When in use, the main chamber is not easy to be partially sunken or tilted, and it has high stability and a high experience.

[0035] See also Figure 1 and Figure 3In this embodiment, the inflatable bed includes a bed body 100, an air pump 200, a one-way valve 300 and a drawstring 400. The bed body 100 is provided with a bed body chamber 101, an upper bed edge chamber 102 and a lower bed edge chamber 103 which are independent of each other. The drawstring 400 is provided in the bed body chamber 101. The drawstring 400 is used to provide a pulling force, so that when the bed body chamber 101 is filled with gas, the expansion of the bed body chamber 101 is suppressed, so that the bed body chamber 101 maintains a set shape, which is convenient for use. The upper bed edge chamber 102 and the lower bed edge chamber 103 are both arranged around the bed body chamber 101, and are respectively located on the top and bottom sides of the bed body chamber 101. The upper bed edge chamber 102 can enhance the stability of the upper bed edge of the bed body chamber 101, and the lower bed edge chamber 103 can enhance the stability of the lower bed edge of the bed body chamber 101 and increase the grip of the inflatable bed. The air pump 200 is connected to the bed body 100 and is configured to inflate the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103. The one-way valve 300 is provided on the air pump 200 or the bed body 100 and is configured to allow only fluid to enter the bed body chamber 101.

[0036] The inflatable bed provided in this embodiment is provided with a bed body chamber 101, an upper bed edge chamber 102 and a lower bed edge chamber 103 which are independent of each other. The upper bed edge chamber 102 and the lower bed edge chamber 103 are both arranged around the bed body chamber 101, and a one-way valve 300 is provided between the bed body chamber 101 and the inflation pump 200. When the bed body chamber 101 and the bed edge chamber are inflated by the inflation pump 200, the gas can directly enter the upper bed edge chamber 102 and the lower bed edge chamber 103, and when the air pressure reaches the set value, the one-way valve 300 is opened, and the bed body chamber 101 is inflated. The upper bed edge chamber 102, the lower bed edge chamber 103 and the bed body chamber 101 do not interfere with each other when being inflated, and inflation is convenient. At the same time, when the inflatable bed is inflated, due to the action of the one-way valve 300, the bed body chamber 101 and the upper bed edge chamber 102, as well as the bed body chamber 101 and the lower bed edge chamber 103 are not interconnected and work independently. During use, the gas in the bed body chamber 101 will not leak into the upper bed edge chamber 102 and the lower bed edge chamber 103, and the bed body chamber 101 is not prone to local pressure fusion and has high stability.

[0037] At the same time, the upper bed edge chamber 102 and the lower bed edge chamber 103 are arranged around the bed body chamber 101, which plays a role in enhancing the stability of the bed body chamber 101. When the top of the inflatable bed is subjected to force on all sides, it is not easy to collapse or tilt locally. During the use of the inflatable bed, the stability is higher and the experience is better.

[0038] See also Figure 1In this embodiment, the inflatable bed optionally includes a top wall 110, a bottom wall 120, a peripheral wall 130, a reinforcement wall and a partition wall 160. The top wall 110 and the bottom wall 120 are both roughly square, the peripheral wall 130 is roughly a rectangular ring, the peripheral wall 130 has two opposite opening sides, the top wall 110 and the bottom wall 120 are both sealed to the peripheral wall 130, and the top wall 110 and the bottom wall 120 respectively seal the two opening sides of the peripheral wall 130. The top wall 110, the bottom wall 120 and the peripheral wall 130 together enclose a bed chamber 101 that is a cube after inflation. There are two reinforcement walls. For ease of description, the two reinforcement walls are respectively a first reinforcement wall 140 and a second reinforcement wall 150. Both reinforcement walls are roughly rectangular rings. The first reinforcement wall 140 is sealed and connected to the top wall 110 and the peripheral wall 130 at the same time, and together form an upper bed edge chamber 102 around the upper edge of the bed body chamber 101. The upper bed edge chamber 102 is in a rectangular ring shape after inflation. The second reinforcement wall 150 is sealed and connected to the top wall and the peripheral wall 130 at the same time, and together form a lower bed edge chamber 103 around the lower edge of the bed body chamber 101. The lower bed edge chamber 103 is in a rectangular ring shape after inflation. When in use, the second reinforcement wall 150 and the bottom end wall 120 are both in contact with the ground, playing a supporting role, and the lower bed edge chamber 103 formed by the second reinforcement wall 150, the peripheral wall 130 and the bottom end wall 120 increases the contact area between the inflatable bed and the ground, thereby increasing the friction between the bottom side of the inflatable bed and the ground, making the inflatable bed more grippy and more stable, playing an anti-slip role. In addition, due to the setting of the lower bed edge chamber 103, the structural strength of the lower bed edge of the bed body chamber 101 is enhanced, the stability is improved, and the comfort of use is improved.

[0039] Please combine Figure 1 and Figure 2Furthermore, the first reinforcement wall 140 includes a first connecting piece 141 and a second connecting piece 142 that are connected. The first connecting piece 141 and the second connecting piece 142 have an angle and form a fold line 143 at the connection point. The side of the first connecting piece 141 away from the fold line 143 is set as a ring-shaped first connecting side 1411, and the side of the second connecting piece 142 away from the fold line 143 is set as a ring-shaped second connecting side 1421. The first connecting side 1411 is connected to the top wall 110, and the second connecting side 1421 is connected to the surrounding wall 130; and after the inflatable bed is inflated, the first connecting piece 141 protrudes from the top wall 110 in the thickness direction of the bed chamber 101. In this way, when the upper bed is inflated along the chamber 102, the first reinforcement wall 140 is stretched open, the first connecting piece 141 and the second connecting piece 142 are both unfolded, and the outer surface of the first connecting piece 141 forms an obtuse angle with the outer surface of the top wall 110. Generally speaking, when the inflatable bed is in normal use, the top wall 110 is roughly a horizontal plane, and the outer surface of the top wall 110 is the surface supporting the human body. The first connecting piece 141 has an upward angle relative to the top wall 110, and the height of the first connecting piece 141 gradually increases in the direction away from the top wall 110, forming an uphill structure, which can play a role of interception and limitation, and can effectively prevent the quilt on the top wall 110 from slipping off, and can also effectively prevent the user from slipping off the inflatable bed when sleeping, with high safety.

[0040] Optionally, the edges of the partition wall 160 are sealed and connected to the inner surface of the peripheral wall 130, and the partition wall 160 and the peripheral wall 130 together define the inflatable chamber 104. The inflatable pump 200 is arranged in the inflatable chamber 104, and the air inlet of the inflatable pump 200 is connected to the through hole on the peripheral wall 130, so that the air inlet of the inflatable pump 200 is connected to the outside. The inflatable chamber 104 is connected to the bed body chamber 101 through the first air delivery pipe 210, and the one-way valve 300 is arranged in the first air delivery pipe 210. The one-way valve 300 can be opened when the air pressure is greater than a preset value, so that the bed body chamber 101 is inflated by the inflatable pump 200. At the same time, the inflatable chamber 104 is connected to the upper bed edge chamber 102 through the second air delivery pipe 220, and is connected to the lower bed edge chamber 103 through the third air delivery pipe 230. Due to the structural design of the inflation chamber 104, the air pump 200 is easy to be installed, and the air pump 200 is located in the inflation chamber 104 without being exposed to the external environment. The air pump 200 is not easily contaminated and has a long service life. The air pump 200 is not protruding from the surrounding wall 130, so the inflatable bed occupies a small space, which is conducive to display.

[0041] Please combine Figure 4At the same time, due to the setting of the inflation chamber 104, when the inflation pump 200 is used to inflate the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103, the gas is first delivered to the inflation chamber 104, and then the gas is distributed to the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103 through the inflation chamber 104. Only one inflation pump 200 is needed to complete the inflation of multiple chambers, simplifying the structure and reducing costs. In addition, during inflation, since a one-way valve 300 is provided in the first gas supply pipe 210, at the initial stage of inflation, the air pressure is low and the one-way valve 300 is in a closed state. The upper bed edge chamber 102 and the lower bed edge chamber 103 are inflated first, and after the inflation reaches the set amount, the one-way valve 300 is opened, so that the three chambers are inflated synchronously. Since the upper bed edge chamber 102 and the lower bed edge chamber 103 are inflated first, the upper bed edge chamber 102 and the lower bed edge chamber 103 are preliminarily inflated and formed first, the bed body chamber 101 can be spread out during the forming process, thereby facilitating the subsequent inflation of the bed body chamber 101, and the folding and inflation of the bed body chamber 101 are less likely to be obstructed, and inflation is smoother.

[0042] In this embodiment, it should be noted that the top wall 110, the bottom wall 120 and the peripheral wall 130 can be sealed and connected by heat sealing process. The first reinforcing wall 140, the top wall 110 and the peripheral wall 130 can be sealed and connected by heat sealing process, and the first reinforcing wall 140 can be heat-sealed and connected to form a rectangular ring by four strips, and then sealed and connected to the top wall 110 and the peripheral wall 130. Similarly, the second reinforcing wall 150, the bottom wall 120 and the peripheral wall 130 can be sealed and connected by heat sealing process, and the second reinforcing wall 150 can be heat-sealed and connected to form a rectangular ring by four strips, and then sealed and connected to the bottom wall 120 and the peripheral wall 130. The partition wall 160 can be sealed and connected to the peripheral wall 130 by heat sealing process.

[0043] In this embodiment, optionally, the elasticity of the top wall 110 is less than that of the bottom wall 120. The greater the elasticity, the lower the PVC hardness value, the lower the PVC hardness value, the greater the expansion coefficient, the greater its elasticity, and the easier it is to deform, that is, the bottom wall 120 is easy to deform the top wall 110. The parameter PHR indicates the number of rubber or resin added to every 100 parts (by mass) of PVC material, and indirectly indicates the PVC hardness of PVC by indirectly adding the number of rubber or resin. In the inflatable bed of this embodiment, the PVC hardness of the top wall 110 is 50-52PHR, and the PVC hardness of the bottom wall 120 is 48-50PHR, which can not only maintain the flatness and aesthetic performance of the inflatable bed, avoid the formation of bread-like protrusions on the surface of the inflatable bed, but also better match the hardness and elasticity of the bed. At the same time, with such a design, since the deformation of the bottom wall 120 is greater than the deformation of the top wall 110, after inflation is completed, the area of ​​the bottom wall 120 that is expanded is greater than the area of ​​the top wall 110, and the overall shape of the inflatable bed is roughly a trapezoidal platform, that is, the outer contour of the cross-section of the inflatable bed is roughly an isosceles trapezoid, and the inflatable bed has higher stability and is safer and more comfortable to use.

[0044] Furthermore, the top wall 110 includes a stacked PVC flocking layer and a PVC / TPU laminated fabric layer, and the bottom wall 120 and the peripheral wall 130 both include a stacked PVC fabric laminated layer and a PVC / TPU layer or a PVC / TPU flocking layer. The flocking layer of the top wall 110 is arranged on the outside of the PVC / TPU layer, that is, on the side away from the bottom wall 120; the fabric layer of the bottom wall 120 and the peripheral wall 130 is arranged on the outside of the PVC / TPU layer, that is, the fabric layer of the bottom wall 120 is arranged on the side of the PVC / TPU layer away from the top wall 110, and the fabric layer of the peripheral wall 130 is arranged on the side of the PVC / TPU layer away from the bed cavity 101. The PVC / TPU layers between the top wall 110 and the peripheral wall 130, and between the bottom wall 120 and the peripheral wall 130 are mutually fused to define the inflation chamber 104. The first reinforcement wall 140 and the second reinforcement wall 150 may both be made of PVC / TPU material.

[0045] In this embodiment, by providing a flocking layer on the top wall 110 of the inflatable bed, the inflatable bed can be made more delicate and breathable, giving people a more comfortable feeling when in contact with human skin, and improving the comfort of use. The fabric layer can reduce the noise generated when the inflatable bed is touched, avoid rupture, and increase the service life of the inflatable bed. In addition, the inflatable bed in the prior art will expand more towards an arc shape after inflation, making the mattress body protrude in a bread-like shape, making the inflatable bed not flat and not beautiful, affecting the service life. The provision of the fabric layer limits the expansion of the PVC / TPU layer, making the overall stretching of the inflatable bed smoother and more beautiful, achieving the technical effect that the inflatable bed as a whole is not easy to deform, and improving the hardness of the inflatable bed, making the inflatable bed more comfortable and having a longer service life.

[0046] In this embodiment, it should be noted that a deflation valve 500 is provided on the peripheral wall 130, and the deflation valve 500 can discharge the gas in the bed cavity 101 after it is opened. In addition, due to the setting of the one-way valve 300, the gas in the upper bed edge cavity 102 and the lower bed edge cavity 103 will not affect the air pressure of the bed cavity 101 when it is discharged, and will not affect the softness, hardness and comfort of the bed cavity 101. It should be understood that the upper bed edge cavity 102 and the lower bed edge cavity 103 can be exhausted by the air pump 200.

[0047] In this embodiment, optionally, the drawstring 400 is set as a flexible belt, the drawstring 400 can be made of a cloth layer, and the drawstring 400 can be a hollow structure. Obviously, in other embodiments, the drawstring 400 can also be a sheet or gourd shape. One end of the drawstring 400 is sealed and connected to the top wall 110, and the other end is sealed and connected to the bottom wall 120. In addition, the number of the drawstrings 400 is multiple, and the multiple drawstrings 400 are arranged in the bed chamber 101 at intervals. It should be understood that each drawstring 400 has an angle with the top wall 110 and the bottom wall 120, and the positional relationship between the drawstring 400 and the bottom wall 120 is described. The angle between the drawstring 400 near the middle of the bed chamber 101 and the bottom wall 120 is 90°, and the ends of the drawstrings 400 far from the middle of the bed chamber 101 connected to the top wall 110 are all inclined near the middle of the bed chamber 101, so that the stability of the inflatable bed is high. For example, the angle between the drawstring 400 and the bottom end wall 120 is between 75° and 90°. For example, the angle between the drawstring 400 and the bottom end wall 120 is 75°, 80°, or 90°.

[0048] It should be noted that the plurality of drawstrings 400 may be arranged in a rectangular array. Obviously, in other embodiments, the plurality of drawstrings 400 may also be arranged in a ring shape.

[0049] The inflatable bed provided in this embodiment has three independent chambers, and annular chambers are distributed on the upper and lower edges of the bed body chamber 101. The overall stability of the inflatable bed is high, and it is not easy to be partially sunken or tilted during use. It is not easy for bedding and users to slide off the inflatable bed, and it is highly comfortable to use. In addition, the three chambers are inflated by the air pump 200 and the inflatable chamber 104, which has a simple structure and low cost. The gas in the bed body chamber 101 is blocked by the one-way valve 300 and will not overflow. Adjusting the air pressure of the upper bed edge chamber 102 and the lower bed edge chamber 103 will not affect the hardness and comfort of the bed body chamber 101.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
