[0002] Inflatable beds are highly flexible and can be used as beds or mattresses when inflated. They are easy to store and carry when not inflated, and are increasingly widely used in leisure and entertainment, healthcare, home life and other places.

[0003] Most inflatable beds have an internal chamber that is inflated with air to provide a certain level of support. Therefore, the support directly impacts the user experience. Existing inflatable beds are typically made of flexible materials, which can easily cause the outer side surfaces to bulge outward during inflation or use. This not only affects the appearance but also causes unstable pressure within the chamber, reducing the support and impacting the user experience. Summary of the Invention

[0058] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0059] Example 1

[0060] See also Figures 1 to 4 An embodiment of the present invention provides a portable inflatable bed, comprising an outer sheet 11, a top sheet 12, a bottom sheet 13 and at least one air inlet and outlet component 2, the edge of the top sheet 12 is connected to the upper edge of the outer sheet 11, the edge of the bottom sheet 13 is connected to the lower edge of the outer sheet 11, an air chamber is formed between the outer sheet 11, the top sheet 12 and the bottom sheet 13, and the air inlet and outlet component 2 can inflate and discharge air into the air chamber.

[0061] The portable inflatable bed also includes an inner sheet 3, which is arranged in a ring inside the outer sheet 11. The upper edge of the inner sheet 3 is connected to the top sheet 12, and the lower edge of the inner sheet 3 is connected to the bottom sheet 13. The inner and outer sides of the inner sheet 3 form an inner air chamber and an outer air chamber. That is, the outer air chamber is formed between the outer sheet 11 and the inner sheet 3, and the inner air chamber is formed inside the inner sheet 3. The inner air chamber and the outer air chamber are connected. The arrangement of the inner sheet 3 provides support between the top sheet 12 and the bottom sheet 13, thereby improving the internal support force. Specifically, the top wall of the outer air chamber is the top sheet 12, the bottom wall of the outer air chamber is the bottom sheet 13, one side wall of the outer air chamber is the outer sheet 11, and the other side wall of the outer air chamber is the inner sheet 3. The outer air chamber is annular. The top wall of the inner air chamber is the top sheet 12, the bottom wall of the inner air chamber is the bottom sheet 13, and the side walls of the inner air chamber are the inner sheet 3.

[0062] The portable inflatable bed also includes at least one transverse tab 4, which is arranged around the interior of the outer air chamber to divide the outer air chamber into at least two transverse outer air chambers. The outer edge of the transverse tab 4 is connected to the inner side of the outer sheet 11, and the inner edge of the transverse tab 4 is connected to the outer side of the inner sheet 3. The transverse outer air chambers are arranged vertically up and down. The provision of the transverse tab 4 provides support within the outer air chamber, providing inward tension to the outer sheet 11 and preventing it from expanding outward. This solves the problem of side bulges, reduces the expansion of the outer sheet 11 after inflation, and prevents excessive outward deformation of the outer sheet 11, thereby more evenly improving the support force. In addition, by providing the transverse tab 4, the design height of the inflatable bed can be increased, that is, even when the inflatable bed is at a high height, it can still provide stable support force.

[0063] A support portion 6 can be provided within the inner air chamber to provide support and enhance the supporting force. The support portion 6 is disposed within the inner air chamber, with its top end connected to the upper wall of the inner air chamber and its bottom end connected to the lower wall of the inner air chamber. The provision of the support portion 6 provides support within the inner air chamber, thereby enhancing the linear supporting force more uniformly in the vertical direction.

[0064] In this embodiment, the top end of the support portion 6 is connected to the top sheet 12 , and the bottom end of the support portion 6 is connected to the bottom sheet 13 .

[0065] Optionally, at least two support portions 6 are provided, and at least two support portions 6 are arranged side by side in the inner air chamber so that the force in the middle of the inflatable mattress is distributed. There is a gap between adjacent support portions 6 to facilitate gas filling. The support portion 6 is cylindrical or sheet-shaped, which is not limited here.

[0066] All the transverse outer air chambers are connected to the inner air chambers, which facilitates inflation and deflation, making the pressure in the inflatable bed uniform. The transverse outer air chambers can be connected to the inner air chambers directly or indirectly.

[0067] At least one first fluid channel 401 is provided on the transverse pull tab 4, and a second fluid channel 301 is provided on the inner air chamber, communicating with at least one transverse outer air chamber. Since the transverse pull tab 4 is ventilated, adjacent transverse outer air chambers can be connected. To achieve communication between the inner air chamber, only one transverse outer air chamber needs to be connected to the inner air chamber.

[0068] When the transverse pull tab 4 cannot be ventilated, each transverse outer air chamber is independent, and a fluid channel 302 is provided on the inner air chamber corresponding to each transverse outer air chamber. At this time, each transverse outer air chamber is directly connected to the inner air chamber.

[0069] In this embodiment, one transverse pull tab 4 is provided, forming two transverse outer air chambers. Figure 5 As shown, when the first fluid channel 401 is provided on the transverse pull tab 4, only one second fluid channel 301 needs to be provided on the inner air chamber to communicate with one of the transverse outer air chambers. Figure 6 As shown, when the transverse pull tab 4 is not ventilated, a fluid channel 302 is provided on the inner air chamber corresponding to each transverse outer air chamber. Of course, it is also possible to provide both the first fluid channel 401 on the transverse pull tab 4 and the second fluid channel 301 on the inner air chamber corresponding to each transverse outer air chamber, which will not be described in detail here.

[0070] The shapes of the top sheet 12 and bottom sheet 13 are not limited and can be rectangular, circular, or oval, depending on the actual situation. The material of the airbed is not limited and can be made of existing lightweight plastics such as PVC, PU, ​​and PE. The connection between the various components of the airbed can be high-frequency welding, hot melt welding, or ultrasonic welding, without limitation.

[0071] The inflatable bed can be inflated and deflated by an air inlet and outlet component 2. The air inlet and outlet component 2 can be an air inlet and outlet valve, which is connected to the air inlet and outlet valve by an external air pump for inflation. The air inlet and outlet component 2 can also be a built-in air pump, which is provided with an air valve for inflation and deflation. Of course, the air inlet and outlet component 2 can also be a combination of an air inlet and outlet valve and a built-in air pump. There is no restriction on the location of the air inlet and outlet component 2, which is generally provided on the outer sheet 11. Of course, in order to improve the efficiency of air intake and deflation, two or even more air inlet and outlet components 2 can be provided, which will not be elaborated here.

[0072] Example 2

[0073] Figures 7 to 9A second embodiment is shown, wherein components identical or corresponding to those in the first embodiment are denoted by the corresponding reference numerals. For simplicity, only the differences between the second embodiment and the first embodiment are described. The differences are that at least two transverse tabs 4 are provided. At least one transverse tab 4 is a lower transverse tab 41, located at the bottom, forming an air chamber surrounding the bottom frame of the bed between the lower transverse tab 41 and the bottom sheet 13. At least one transverse tab 4 is an upper transverse tab 42, located at the top, forming an air chamber surrounding the top frame of the bed between the upper transverse tab 42 and the top sheet 12. By increasing the number of transverse tabs 4, the structural strength of the airbed is ensured, the support force of the airbed is further increased, the side of the airbed is prevented from protruding outward, and the airbed is evenly layered in the vertical direction.

[0074] See also Figure 7 and Figure 8 Two transverse tabs 4 are provided, dividing the outer air chamber into three transverse outer air chambers. One transverse tab 4 is a lower transverse tab 41, and the other transverse tab 4 is an upper transverse tab 42. The inner air chamber and the three transverse outer air chambers can be connected by providing a first fluid channel 401 on the transverse tab 4, and then providing only one second fluid channel 301 on the inner air chamber to communicate with one of the transverse outer air chambers. Alternatively, the transverse tabs 4 are not ventilated, and the inner air chamber is provided with a fluid channel 302 corresponding to each transverse outer air chamber.

[0075] See also Figure 9 Three transverse pull tabs 4 are provided to divide the outer air chamber into four transverse outer air chambers, two of which are lower transverse pull tabs 41, and one transverse pull tab 4 is an upper transverse pull tab 42. The communication method between the inner air chamber and the four transverse outer air chambers will not be described here in detail, and reference can be made to the above description.

[0076] Example 3

[0077] Figures 10 to 14 A third embodiment is shown, wherein components identical or corresponding to those in the second embodiment are designated by the corresponding reference numerals. For simplicity, only the differences between the third embodiment and the second embodiment will be described. The differences are that the connection between the inner edge of the lower transverse tab 41 and the outer side of the inner peripheral sheet 3 is located near the bottom sheet 13, and the outer edge of the lower transverse tab 41 is higher than the inner edge of the lower transverse tab 41. This allows the lower transverse tab 41 to apply an inward pulling force to the peripheral sheet 11, with the pulling force directed from the outer edge of the lower transverse tab 41 to the inner edge of the lower transverse tab 41. This results in a downward, oblique pulling force applied to the lower portion of the peripheral sheet 11, further improving the stability of the peripheral sheet 11.

[0078] Alternatively, the connection between the inner edge of the upper transverse pull tab 42 and the outer side of the inner peripheral sheet 3 can be arranged close to the top sheet 12, and the outer edge of the upper transverse pull tab 42 can be lower than the inner edge of the upper transverse pull tab 42. This allows the upper transverse pull tab 42 to apply an inward pulling force to the peripheral sheet 11, and the direction of the pulling force is from the outer edge of the upper transverse pull tab 42 to the inner edge of the upper transverse pull tab 42, that is, an oblique upward pulling force is applied to the upper part of the peripheral sheet 11, which is more conducive to improving the stability of the peripheral sheet 11.

[0079] Furthermore, both the upper transverse pull tab 42 and the lower transverse pull tab 41 may be arranged at an angle, which will not be described in detail here.

[0080] Furthermore, when three transverse pull tabs 4 are provided, two may be upper transverse pull tabs 42 and one may be a lower transverse pull tab 41. One of the two upper transverse pull tabs 42 is provided parallel to the bottom sheet 13, and the inner edge of the other is connected to the outer side of the inner peripheral sheet 3 close to the top sheet 12, and the outer edge of the upper transverse pull tab 42 is lower than the inner edge of the upper transverse pull tab 42. The upper transverse pull tab 42 provided parallel to the bottom sheet 13 is connected to the middle position of the peripheral sheet.

[0081] Furthermore, when three transverse pull tabs 4 are provided, two may be lower transverse pull tabs 41 and one may be an upper transverse pull tab 42. One of the two lower transverse pull tabs 41 is arranged parallel to the bottom sheet 13, and the inner edge of the other is connected to the outer side of the inner peripheral sheet 3 near the bottom sheet 13, and the outer edge is higher than the inner edge of the lower transverse pull tab 41. The lower transverse pull tab 41, which is arranged parallel to the bottom sheet 13, is connected to the middle position of the peripheral sheet.

[0082] When the number of the transverse pull tabs 4 is further increased, the number of the transverse pull tabs 4 parallel to the bottom sheet 13 and the number of the transverse pull tabs 4 inclined relative to the bottom sheet 13 can be set as needed.

[0083] Example 4

[0084] Figure 15 and Figure 16 A fourth embodiment is shown, wherein components identical or corresponding to those in the first embodiment are denoted by the corresponding reference numerals. For simplicity, only the differences between the fourth embodiment and the first embodiment will be described. The difference lies in the inclusion of a transverse spacer 5, which is disposed within the inner air chamber and parallel to the bottom sheet 13. The outer edges of the transverse spacer 5 are connected to the inner side of the inner sheet 3, dividing the inner air chamber into an upper inner chamber and a lower inner chamber. The transverse spacer 5 provides support within the inner air chamber, reducing outward expansion of the inner sheet 3 after inflation and preventing excessive outward deformation, thereby providing better support.

[0085] Optionally, a vent hole is provided on the transverse partition 5 so that the upper inner air chamber and the lower inner air chamber separated by the transverse partition 5 are connected. During inflation, gas can flow in the inner air chamber through the vent hole.

[0086] Optionally, at least two transverse partitions 5 are provided to further ensure the structural strength of the inflatable mattress and increase the supporting force. At least two transverse partitions 5 are arranged vertically in the inner air chamber to divide the inner air chamber into multiple air chambers in the upper and lower directions.

[0087] The transverse partition 5 can be arranged on the same plane as the transverse pull-tab 4 , or can be arranged offset from the transverse pull-tab 4 , which will not be described in detail here.

[0088] When the support portion 6 is placed in the inner air chamber, since the inner air chamber is divided into an upper inner air chamber and a lower inner air chamber by the transverse partition 5, the support portion 6 is placed in both the upper inner air chamber and the lower inner air chamber, providing a stronger support effect. The support portion 6 located in the upper inner air chamber is the upper support portion, with its top end connected to the top sheet 12 and its bottom end connected to the transverse partition 5. The support portion 6 located in the lower inner air chamber is the lower support portion, with its top end connected to the transverse partition 5 and its bottom end connected to the bottom sheet 13.

[0089] Example 5

[0090] Figures 17 to 19 A fifth embodiment is shown, wherein components identical or corresponding to those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For simplicity, only the differences between the fifth embodiment and the first embodiment are described. The difference lies in the inclusion of a transverse spacer 5, which is arranged parallel to the bottom sheet 13. The outer edge of the transverse spacer 5 is connected to the inner side of the outer sheet 11. The transverse spacer 5 separates the inner sheet 3 into an independently arranged upper inner sheet 31 and a lower inner sheet 32. The inner and outer sides of the upper inner sheet 31 form an upper inner air chamber and an upper outer air chamber, while the inner and outer sides of the lower inner sheet 32 ​​form a lower inner air chamber and a lower outer air chamber. The transverse spacer 5, as a whole, simultaneously separates the outer and inner air chambers, allowing the air mattress to have better support with fewer components, thereby ensuring the stability of the air mattress.

[0091] When there is one transverse pull tab 4, the transverse pull tab 4 can be set in the lower outer air chamber or in the upper outer air chamber. When there are at least two transverse pull tabs 4, the lower transverse pull tab 41 is set in the lower outer air chamber, and the upper transverse pull tab 42 is set in the upper outer air chamber. The arrangement of the lower transverse pull tab 41 in the lower outer air chamber can refer to Example 2, and the arrangement of the upper transverse pull tab 42 in the upper outer air chamber can refer to Example 2.

[0092] The second embodiment will not be described in detail here.

[0093] The transverse partition 5 is provided with ventilation holes, so that the upper inner air chamber is connected to the lower inner air chamber and / or the upper outer air chamber is connected to the lower outer air chamber. As long as one air inlet and outlet component 2 can be used to inflate and deflate all the air chambers in the inflatable bed, it can be sufficient.

[0094] The upper inner sheet 31 and the lower inner sheet 32 ​​may be arranged on the same plane, or may be staggered relative to the transverse partition 5 , which is not limited here.

[0095] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
