The upperbed edge chamber102 and the lowerbed edge chamber103 are both arranged around thebed body chamber101, and are respectively located at the top side and bottom side of thebed body chamber101. The upperbed edge chamber102 can enhance the stability of the upper bed edge of thebed body chamber101. The lowerbed edge chamber103 can enhance the stability of the lower bed edge of thebed body chamber101 and increase the grip of the inflatable bed. Theinflator pump200 is connected to the bedmain body100. Theinflator pump200 is configured to inflate thebed body chamber101, the upperbed edge chamber102 and the lowerbed edge chamber103. The one-way valve300 is provided on theinflator pump200 or the bedmain body100, and the one-way valve300 is configured to allow only fluid to enter thebed body chamber101.
By providing thebed body chamber101, the upperbed edge chamber102 and the lowerbed edge chamber103, which are independent from each other, arranging both the upperbed edge chamber102 and the lowerbed edge chamber103 around thebed body chamber101, and providing the one-way valve300 between thebed body chamber101 and theinflator pump200, when theinflator pump200 is used to inflate thebed body chamber101 and bed edge chambers, gas can directly enter the upperbed edge chamber102 and the lowerbed edge chamber103, and when the gas pressure reaches the set value, the one-way valve300 is opened, thebed body chamber101 is inflated, and the upperbed edge chamber102, the lowerbed edge chamber103 and thebed body chamber101 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 valve300, thebed body chamber101 and the upperbed edge chamber102, and thebed body chamber101 and the lowerbed edge chamber103 do not communicate with each other and work independently, such that during use, the gas in thebed body chamber101 does not leak into the upperbed edge chamber102 and the lowerbed edge chamber103, and thebed body chamber101 does not easily have the situation of local pressure sudden change, and has high stability.
The upperbed edge chamber102 and the lowerbed edge chamber103 are arranged around thebed body chamber101 to enhance the stability of thebed body chamber101, 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 toFIG.1, in the present embodiment, optionally, the inflatable bed comprises atop end wall110, abottom end wall120, aperipheral wall130, reinforcing walls and a dividingwall160. Thetop end wall110 and thebottom end wall120 are both in an approximately square shape, theperipheral wall130 is in a shape of an approximate rectangular ring, theperipheral wall130 has two open sides opposite to each other, thetop end wall110 and thebottom end wall120 are both sealingly connected with theperipheral wall130, and thetop end wall110 and thebottom end wall120 seals the two opening sides of theperipheral wall130 respectively. Thetop end wall110, thebottom end wall120 and theperipheral wall130 jointly enclose thebed body chamber101 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 reinforcingwall140 and a second reinforcingwall150, the two reinforcing walls are all in a shape of a roughly rectangular ring, and the first reinforcingwall140 is simultaneously sealingly connected with thetop end wall110 and theperipheral wall130, jointly forming the upperbed edge chamber102 surrounding the upper edge of thebed body chamber101. The upperbed edge chamber102 is in a rectangular ring shape after being inflated. The second reinforcingwall150 is simultaneously sealingly connected with the top wall and theperipheral wall130, jointly forming the lowerbed edge chamber103 surrounding the lower edge of thebed body chamber101, and the lowerbed edge chamber103 is in a rectangular ring shape after being inflated. When in use, the second reinforcingwall150 and thebottom end wall120 are both in contact with the ground, which plays a supporting role. In addition, the lowerbed edge chamber103 jointly formed by the second reinforcingwall150, theperipheral wall130 and thebottom end wall120 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 lowerbed edge chamber103, the structural strength of the lower bed edge of thebed body chamber101 is enhanced, the stability is improved, and the comfort of use is improved.
Referring toFIG.1 andFIG.2, further, the first reinforcingwall140 comprises a first connectingpiece141 and a second connectingpiece142 that are connected with each other, the first connectingpiece141 and the second connectingpiece142 have an included angle and afold line143 formed at the joint thereof, one side of the first connectingpiece141 away from thefold line143 is provided as an annular first connectingside1411, and one side of the second connectingpiece142 away from thefold line143 is provided as an annular second connectingside1421, the annular first connectingside1411 is connected to thetop end wall110, and the annular second connectingside1421 is connected to theperipheral wall130, and after the inflatable bed is inflated, the first connectingpiece141 protrudes from thetop end wall110 in the thickness direction of thebed body chamber101. In this way, after the inflation of the upperbed edge chamber102 is completed, the first reinforcingwall140 is stretched, the first connectingpiece141 and the second connectingpiece142 are both expanded, and the outer surface of first connectingpiece141 and the outer surface of thetop end wall110 form an obtuse angle. Generally, when the inflatable bed is in normal use, thetop end wall110 is approximately a horizontal plane, and the outer surface of thetop end wall110 is a surface that supports the human body, the first connectingpiece141 has an upward angle relative to thetop end wall110, and the height of the first connectingpiece141 in the direction away from thetop end wall110 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, thetop end wall110 can effectively prevent the quilt on thetop end wall110 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 dividingwall160 are all sealingly connected with the inner surface of theperipheral wall130, the dividingwall160 and theperipheral wall130 jointly define aninflatable chamber104, theinflator pump200 is provided in theinflatable chamber104, and the gas inlet of theinflator pump200 communicates with the through hole of theperipheral wall130, so that the gas inlet of theinflator pump200 communicates with the outside. Theinflatable chamber104 communicates with thebed body chamber101 through a firstgas delivery pipe210, the one-way valve300 is provided in the firstgas delivery pipe210, and the one-way valve300 can be opened when gas pressure is greater than a preset value, thereby inflating thebed body chamber101 through theinflator pump200. Theinflatable chamber104 communicates with the upperbed edge chamber102 through a secondgas delivery pipe220 and communicates with the lowerbed edge chamber103 through a thirdgas delivery pipe230. Due to the structural design of theinflatable chamber104, it is convenient to provide theinflator pump200, and theinflator pump200 is located in theinflatable chamber104 without being exposed to the external environment, and theinflator pump200 is not easy to be contaminated and has a long service life, and theinflator pump200 is provided not to protrude theperipheral wall130, such that the inflatable bed occupies a small space, which is convenient for arrangement.
Referring toFIG.4, due to the arrangement of theinflatable chamber104, when theinflator pump200 is used to inflate thebed body chamber101, the upperbed edge chamber102 and the lowerbed edge chamber103, the gas is first delivered to theinflatable chamber104, and then the gas is distributed to thebed body chamber101, the upperbed edge chamber102 and the lowerbed edge chamber103 through theinflatable chamber104. Theinflator pump200 is provided to complete inflation of multiple chambers, which simplifies the structure and reduces the cost. In addition, when inflating, since the one-way valve300 is provided in the firstgas delivery pipe210, in the initial stage of inflation, the gas pressure is low, and the one-way valve300 is in a closed state, and the upperbed edge chamber102 and the lowerbed edge chamber103 are inflated first, and after the inflated gas reaches the set amount, the one-way valve300 is opened to inflate the three chambers synchronously. Since the upperbed edge chamber102 and the lowerbed edge chamber103 are inflated first, the upperbed edge chamber102 and the lowerbed edge chamber103 are preliminarily inflated and shaped, wherein in the shaping process, thebed body chamber101 can be spread out, so as to facilitate the subsequent inflation of thebed body chamber101, and the folding and inflation of thebed body chamber101 are not easily blocked, and the inflation is smoother.
In the present embodiment, it should be noted that thetop end wall110, thebottom end wall120, and theperipheral wall130 may all be sealingly connected by a heat-sealing process. The first reinforcingwall140, thetop end wall110 and theperipheral wall130 may be sealingly connected by the heat-sealing process, and the first reinforcingwall140 may be obtained by connecting four strip-shaped pieces by heat sealing to form a rectangular ring, and then be sealingly connected with thetop end wall110 and theperipheral wall130. In the same way, the second reinforcingwall150, thebottom end wall120 and theperipheral wall130 may be sealingly connected by the heat-sealing process, and the second reinforcingwall150 may be obtained by connecting four strip-shaped pieces by heat sealing to form a rectangular ring, and be sealingly connected with thebottom end wall120 and theperipheral wall130. The dividingwall160 may be sealingly connected with theperipheral wall130 by the heat-sealing process.
In the present embodiment, optionally, the stretchability of thetop end wall110 is less than the stretchability of thebottom end wall120. 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, thebottom end wall120 is easier to deform than thetop end wall110. 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 thetop end wall110 is 50-52 PHR, and the PVC hardness of thebottom end wall120 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 thebottom end wall120 is greater than the deformation of thetop end wall110, after the inflation is completed, the expanded area of thebottom end wall120 is larger than the expanded area of thetop end wall110, 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, thetop end wall110 comprises a PVC flocking layer and a PVC/thermoplastic polyurethane (TPU) adhered cloth layer, which are laminated, and thebottom end wall120 and theperipheral wall130 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 thetop end wall110 is provided on the outside of the PVC/TPU layer, that is, on the side away from thebottom end wall120, the cloth layers of thebottom end wall120 and theperipheral wall130 are provided on the outside of the PVC/TPU layer, that is, the cloth layer of thebottom end wall120 is provided on the side of the PVC/TPU layer away from thetop end wall110, and the cloth layer of theperipheral wall130 are provided on the side of the PVC/TPU layer away from thebed body chamber101. The PVC/TPU layers between thetop end wall110 and theperipheral wall130 and between thebottom end wall120 and theperipheral wall130 are welded to each other to jointly define theinflatable chamber104. The first reinforcingwall140 and the second reinforcingwall150 may both be made of the PVC/TPU material.
In the present embodiment, by providing the flocking layer on thetop end wall110 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 agas escape valve500 is provided on theperipheral wall130, and thegas escape valve500 can discharge the gas in thebed body chamber101 after being opened. In addition, due to the arrangement of the one-way valve300, when the gas in the upperbed edge chamber102 and the lowerbed edge chamber103 is discharged, the gas pressure of thebed body chamber101 is not affected, and the hardness and comfort of thebed body chamber101 are not affected. It should be understood that the upperbed edge chamber102 and the lowerbed edge chamber103 may be exhausted by theinflator pump200.
In the present embodiment, optionally, thepull strap400 is provided as a flexible strap (e.g., a belt, a band), thepull strap400 may be made of a cloth layer, and thepull strap400 may be in a hollow structure. Obviously, in other embodiments, thepull strap400 may also be in a sheet shape or a gourd shape or the like. One end of thepull strap400 is sealingly connected with thetop end wall110, and the other end is sealingly connected with thebottom end wall120. In addition, there may bemultiple pull straps400, and themultiple pull straps400 are arranged in thebed body chamber101 at intervals. It should be understood that eachpull strap400 has an included angle with each of thetop end wall110 and thebottom end wall120, and the position relationship between thepull strap400 and thebottom end wall120 is used for description. The angle between thebottom end wall120 and thepull strap400 near the middle of thebed body chamber101 is 90°, and one end of thepull strap400 connected to thetop end wall110 is inclined close to the middle of thebed body chamber101, so that the pull strap is angled away from the middle of thebed body chamber101, and in this way, the stability of the inflatable bed is high. For example, an angle between thepull strap400 and thebottom end wall120 is between 75° and 90°. For example, the angle between thepull strap400 and thebottom end wall120 is 75°, 80°, 90°, or the like.
It should be noted that themultiple pull strap400 may be arranged in a rectangular array. Obviously, in other embodiments, themultiple pull strap400 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 thebed body chamber101, 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 theinflator pump200 and theinflatable chamber104, enabling simple structure and low cost. The gas in thebed body chamber101 is blocked by the one-way valve300 and does not overflow, and adjusting the gas pressures of the upperbed edge chamber102 and the lowerbed edge chamber103 does not affect the hardness and comfort of thebed body chamber101.
The above are exemplary embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modifications, equivalent replacements, improvements, and the like made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
