Referring to FIG. 1 and FIG. 3, in the present embodiment, an inflatable bed comprises a bed main body 100, an inflator pump 200, a one-way valve 300 and a pull strap 400. The bed main body 100 is provided with a bed body chamber 101, an upper bed edge chamber 102 and a lower bed edge chamber 10, which are independent from each other, The pull strap 400 is provided in the bed body chamber 101, and the pull strap 400 is used to provide tension, such that when the bed body chamber 101 is filled with gas, the expansion of the bed body chamber 101 is suppressed, and such that the bed body chamber 101 maintains the 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 at the top side and bottom side 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. 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 inflator pump 200 is connected to the bed main body 100. The inflator pump 200 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 inflator pump 200 or the bed main body 100, and the one-way valve 300 is configured to allow only fluid to enter the bed body chamber 101.
By providing the bed body chamber 101, the upper bed edge chamber 102 and the lower bed edge chamber 103, which are independent from each other, arranging both the upper bed edge chamber 102 and the lower bed edge chamber 103 around the bed body chamber 101, and providing the one-way valve 300 between the bed body chamber 101 and the inflator pump 200, when the inflator pump 200 is used to inflate the bed body chamber 101 and bed edge chambers, gas can directly enter the upper bed edge chamber 102 and the lower bed edge chamber 103, and when the gas pressure reaches the set value, the one-way valve 300 is opened, the bed body chamber 101 is inflated, and 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, such that the inflation is convenient. After the inflation of inflatable bed is completed, due to function of the one-way valve 300, the bed body chamber 101 and the upper bed edge chamber 102, and the bed body chamber 101 and the lower bed edge chamber 103 do not communicate with each other and work independently, such that during use, the gas in the bed body chamber 101 does not leak into the upper bed edge chamber 102 and the lower bed edge chamber 103, and the bed body chamber 101 does not easily have the situation of local pressure sudden change, and has high stability.
The upper bed edge chamber 102 and the lower bed edge chamber 103 are arranged around the bed body chamber 101 to enhance the stability of the bed body chamber 101, and the inflatable bed is not easily collapsed or tilted locally when the periphery of the top is stressed, and during the use of the inflatable bed, the stability is high and the experience is enhanced.
Referring to FIG. 1, in the present embodiment, optionally, the inflatable bed comprises a top end wall 110, a bottom end wall 120, a peripheral wall 130, reinforcing walls and a dividing wall 160. The top end wall 110 and the bottom end wall 120 are both in an approximately square shape, the peripheral wall 130 is in a shape of an approximate rectangular ring, the peripheral wall 130 has two open sides opposite to each other, the top end wall 110 and the bottom end wall 120 are both sealingly connected with the peripheral wall 130, and the top end wall 110 and the bottom end wall 120 seals the two opening sides of the peripheral wall 130 respectively. The top end wall 110, the bottom end wall 120 and the peripheral wall 130 jointly enclose the bed body chamber 101 that is in a cuboid shape after being inflated. Two reinforcing walls are provided, for ease of description. The two reinforcing walls are respectively a first reinforcing wall 140 and a second reinforcing wall 150, the two reinforcing walls are all in a shape of a roughly rectangular ring, and the first reinforcing wall 140 is simultaneously sealingly connected with the top end wall 110 and the peripheral wall 130, jointly forming the upper bed edge chamber 102 surrounding the upper edge of the bed body chamber 101. The upper bed edge chamber 102 is in a rectangular ring shape after being inflated. The second reinforcing wall 150 is simultaneously sealingly connected with the top wall and the peripheral wall 130, jointly forming the lower bed edge chamber 103 surrounding the lower edge of the bed body chamber 101, and the lower bed edge chamber 103 is in a rectangular ring shape after being inflated. When in use, the second reinforcing wall 150 and the bottom end wall 120 are both in contact with the ground, which plays a supporting role. In addition, the lower bed edge chamber 103 jointly formed by the second reinforcing 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, so that the grip of the inflatable bed is greater, and the grip is more stable, which has a non-slip effect. In addition, due to the arrangement 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.
Referring to FIG. 1 and FIG. 2, further, the first reinforcing wall 140 comprises a first connecting piece 141 and a second connecting piece 142 that are connected with each other, the first connecting piece 141 and the second connecting piece 142 have an included angle and a fold line 143 formed at the joint thereof, one side of the first connecting piece 141 away from the fold line 143 is provided as an annular first connecting side 1411, and one side of the second connecting piece 142 away from the fold line 143 is provided as an annular second connecting side 1421, the annular first connecting side 1411 is connected to the top end wall 110, and the annular second connecting side 1421 is connected to the peripheral wall 130, and after the inflatable bed is inflated, the first connecting piece 141 protrudes from the top end wall 110 in the thickness direction of the bed body chamber 101. In this way, after the inflation of the upper bed edge chamber 102 is completed, the first reinforcing wall 140 is stretched, the first connecting piece 141 and the second connecting piece 142 are both expanded, and the outer surface of first connecting piece 141 and the outer surface of the top end wall 110 form an obtuse angle. Generally, when the inflatable bed is in normal use, the top end wall 110 is approximately a horizontal plane, and the outer surface of the top end wall 110 is a surface that supports the human body, the first connecting piece 141 has an upward angle relative to the top end wall 110, and the height of the first connecting piece 141 in the direction away from the top end wall 110 gradually increases, forming an uphill or upward structure, thereby serving to limit, contain, or capture items located on top of the inflatable bed. In this manner, the top end wall 110 can effectively prevent the quilt on the top end wall 110 from slipping off, and can also effectively prevent the user from slipping off the inflatable bed while sleeping, and has enhanced safety.
Optionally, the peripheral edges of the dividing wall 160 are all sealingly connected with the inner surface of the peripheral wall 130, the dividing wall 160 and the peripheral wall 130 jointly define an inflatable chamber 104, the inflator pump 200 is provided in the inflatable chamber 104, and the gas inlet of the inflator pump 200 communicates with the through hole of the peripheral wall 130, so that the gas inlet of the inflator pump 200 communicates with the outside. The inflatable chamber 104 communicates with the bed body chamber 101 through a first gas delivery pipe 210, the one-way valve 300 is provided in the first gas delivery pipe 210, and the one-way valve 300 can be opened when gas pressure is greater than a preset value, thereby inflating the bed body chamber 101 through the inflator pump 200. The inflatable chamber 104 communicates with the upper bed edge chamber 102 through a second gas delivery pipe 220 and communicates with the lower bed edge chamber 103 through a third gas delivery pipe 230. Due to the structural design of the inflatable chamber 104, it is convenient to provide the inflator pump 200, and the inflator pump 200 is located in the inflatable chamber 104 without being exposed to the external environment, and the inflator pump 200 is not easy to be contaminated and has a long service life, and the inflator pump 200 is provided not to protrude the peripheral wall 130, such that the inflatable bed occupies a small space, which is convenient for arrangement.
Referring to FIG. 4, due to the arrangement of the inflatable chamber 104, when the inflator 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 inflatable 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 inflatable chamber 104. The inflator pump 200 is provided to complete inflation of multiple chambers, which simplifies the structure and reduces the cost. In addition, when inflating, since the one-way valve 300 is provided in the first gas delivery pipe 210, in the initial stage of inflation, the gas pressure is low, and the one-way valve 300 is in a closed state, and the upper bed edge chamber 102 and the lower bed edge chamber 103 are inflated first, and after the inflated gas reaches the set amount, the one-way valve 300 is opened to inflate the three chambers 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 shaped, wherein in the shaping process, the bed body chamber 101 can be spread out, so as to facilitate the subsequent inflation of the bed body chamber 101, and the folding and inflation of the bed body chamber 101 are not easily blocked, and the inflation is smoother.
In the present embodiment, it should be noted that the top end wall 110, the bottom end wall 120, and the peripheral wall 130 may all be sealingly connected by a heat-sealing process. The first reinforcing wall 140, the top end wall 110 and the peripheral wall 130 may be sealingly connected by the heat-sealing process, and the first reinforcing wall 140 may be obtained by connecting four strip-shaped pieces by heat sealing to form a rectangular ring, and then be sealingly connected with the top end wall 110 and the peripheral wall 130. In the same way, the second reinforcing wall 150, the bottom end wall 120 and the peripheral wall 130 may be sealingly connected by the heat-sealing process, and the second reinforcing wall 150 may be obtained by connecting four strip-shaped pieces by heat sealing to form a rectangular ring, and be sealingly connected with the bottom end wall 120 and the peripheral wall 130. The dividing wall 160 may be sealingly connected with the peripheral wall 130 by the heat-sealing process.
In the present embodiment, optionally, the stretchability of the top end wall 110 is less than the stretchability of the bottom end wall 120. In the above, the greater the stretchability, the lower the polyvinyl chloride (PVC) hardness value, and the lower the PVC hardness value, the greater the expansion coefficient, and the greater the stretchability, the easier it is to deform, that is, the bottom end wall 120 is easier to deform than the top end wall 110. The parameter parts per hundred resin (PHR) means that the number of parts of rubber or resin added to every 100 parts by mass of PVC material, and the number of parts of the rubber or resin added indirectly indicates the PVC hardness of PVC. In the above, in the inflatable bed of the present embodiment, the PVC hardness of the top end wall 110 is 50-52 PHR, and the PVC hardness of the bottom end wall 120 is 48-50 PHR, which not only can keep the flatness and enhanced performance of the inflatable bed and avoid the formation of bread-shaped protrusions on the surface of the inflatable bed, but also achieve better matching and adaptation with the hardness and stretchability of the bed body. With this design, since the deformation of the bottom end wall 120 is greater than the deformation of the top end wall 110, after the inflation is completed, the expanded area of the bottom end wall 120 is larger than the expanded area of the top end wall 110, the overall shape of the inflatable bed is roughly a trapezoidal platform, that is, the cross-sectional outline of the inflatable bed is roughly an isosceles trapezoid, such that the stability of the inflatable bed is high, and the use is safer and more comfortable.
Further, the top end wall 110 comprises a PVC flocking layer and a PVC/thermoplastic polyurethane (TPU) adhered cloth layer, which are laminated, and the bottom end wall 120 and the peripheral wall 130 each comprise a PVC cloth adhered layer and a PVC/TPU layer or a PVC/TPU flocking layer, which are laminated. In the above, the flocking layer of the top end wall 110 is provided on the outside of the PVC/TPU layer, that is, on the side away from the bottom end wall 120, the cloth layers of the bottom end wall 120 and the peripheral wall 130 are provided on the outside of the PVC/TPU layer, that is, the cloth layer of the bottom end wall 120 is provided on the side of the PVC/TPU layer away from the top end wall 110, and the cloth layer of the peripheral wall 130 are provided on the side of the PVC/TPU layer away from the bed body chamber 101. The PVC/TPU layers between the top end wall 110 and the peripheral wall 130 and between the bottom end wall 120 and the peripheral wall 130 are welded to each other to jointly define the inflatable chamber 104. The first reinforcing wall 140 and the second reinforcing wall 150 may both be made of the PVC/TPU material.
In the present embodiment, by providing the flocking layer on the top end 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 cloth layer can reduce the noise generated when the inflatable bed is touched, avoid breakage, and prolong the service life of the inflatable bed. In addition, after the prior art inflatable bed is inflated, the prior art inflatable bed expands more toward the arc-shaped shape, such that the mattress body presents a bread-like protrusion, and the prior art inflatable bed is not flat enough and not beautiful enough, which affects the service life. By contrast, the arrangement of the cloth layer of the present disclosure limits the expansion of the PVC/TPU layer, which makes the overall stretch of the inflatable bed smoother/flat and more beautiful, realizes the technical effects that the entire inflatable bed is not easily deformed, the hardness of inflatable bed is improved, and the inflatable bed is enabled to be more comfortable and has longer service life.
In the present embodiment, it should be noted that a gas escape valve 500 is provided on the peripheral wall 130, and the gas escape valve 500 can discharge the gas in the bed body chamber 101 after being opened. In addition, due to the arrangement of the one-way valve 300, when the gas in the upper bed edge chamber 102 and the lower bed edge chamber 103 is discharged, the gas pressure of the bed body chamber 101 is not affected, and the hardness and comfort of the bed body chamber 101 are not affected. It should be understood that the upper bed edge chamber 102 and the lower bed edge chamber 103 may be exhausted by the inflator pump 200.
In the present embodiment, optionally, the pull strap 400 is provided as a flexible strap (e.g., a belt, a band), the pull strap 400 may be made of a cloth layer, and the pull strap 400 may be in a hollow structure. Obviously, in other embodiments, the pull strap 400 may also be in a sheet shape or a gourd shape or the like. One end of the pull strap 400 is sealingly connected with the top end wall 110, and the other end is sealingly connected with the bottom end wall 120. In addition, there may be multiple pull straps 400, and the multiple pull straps 400 are arranged in the bed body chamber 101 at intervals. It should be understood that each pull strap 400 has an included angle with each of the top end wall 110 and the bottom end wall 120, and the position relationship between the pull strap 400 and the bottom end wall 120 is used for description. The angle between the bottom end wall 120 and the pull strap 400 near the middle of the bed body chamber 101 is 90°, and one end of the pull strap 400 connected to the top end wall 110 is inclined close to the middle of the bed body chamber 101, so that the pull strap is angled away from the middle of the bed body chamber 101, and in this way, the stability of the inflatable bed is high. For example, an angle between the pull strap 400 and the bottom end wall 120 is between 75° and 90°. For example, the angle between the pull strap 400 and the bottom end wall 120 is 75°, 80°, 90°, or the like.
It should be noted that the multiple pull strap 400 may be arranged in a rectangular array. Obviously, in other embodiments, the multiple pull strap 400 may also be arranged in a ring shape or the like.
For the inflatable bed provided by the present embodiment, by providing three independent chambers, and distributing annular chambers at the upper bed edge and the lower bed edge of the bed body chamber 101, the overall stability of the inflatable bed is high, and it is not prone to partial dent or tilt when in use, such that the items and the user on the bed are all not easy to slip off the inflatable bed, and the use comfort is enhanced. In addition, the three chambers are inflated by the cooperation of the inflator pump 200 and the inflatable chamber 104, enabling simple structure and low cost. The gas in the bed body chamber 101 is blocked by the one-way valve 300 and does not overflow, and adjusting the gas pressures of the upper bed edge chamber 102 and the lower bed edge chamber 103 does not affect the hardness and comfort of the bed body chamber 101.
