[0027] Therefore, the detailed description below of the embodiments of the present disclosure provided in the drawings is not intended to limit the claimed scope of the present disclosure, but merely represents chosen embodiments of the present disclosure.

[0029] In the description of the present disclosure, it should be noted that orientation or positional relationships indicated by terms such as center, upper, lower, left, right, vertical, horizontal, inner, and outer are based on orientation or positional relationships as shown in the drawings, or orientation or positional relationships of a product of the present disclosure when being conventionally placed in use, merely for facilitating describing the present disclosure and simplifying the description, rather than indicating or suggesting that related devices or elements have to be in the specific orientation or configured and operated in a specific orientation, therefore, they should not be construed as limitation to the present disclosure. Besides, terms first, second, third, etc. are merely for distinguishing the description, but should not be construed as indicating or implying importance in the relativity.

[0030] Moreover, terms horizontal, vertical and the like do not mean that the parts are required to be absolutely horizontal or overhanging, but may be slightly inclined. For example, by horizontal it merely means that a structure is more horizontal in comparison with vertical, rather than being completely horizontal, while the structure can be slightly inclined.

[0031] In the description of the present disclosure, it should be further noted that, unless otherwise specifically specified and defined, the terms set, install, link, and connect should be understood in a broad sense, for example, a connection may be a fixed connection, a detachable connection, or an integrated connection; it may be a mechanical connection or an electrical connection; it may be direct joining or indirect joining through an intermediate medium, and it also may be inner communication between two elements. For a person ordinarily skilled in the art, specific meanings of the above-mentioned terms in the present disclosure could be understood according to specific circumstances.

[0032] Currently, an inflatable bed with three air chambers includes a bed body, a first inclined reinforcing pull strap 400 and a second inclined reinforcing pull strap 400, wherein the first inclined reinforcing pull strap 400 is connected to a top portion and a periphery portion of the bed body, the second inclined reinforcing pull strap 400 is connected to a bottom portion and the periphery portion of the bed body, and in order to achieve communication between the air chambers, through holes are provided on both the first inclined reinforcing pull strap 400 and the second inclined reinforcing pull strap 400. In this way, when manufacturing the inflatable bed with three air chambers in the prior art, two steps are required. One step is fixedly connecting the inclined reinforcing pull strap 400 to the bed body, and the other step is providing holes on the inclined reinforcing pull strap 400, which process is cumbersome and has low efficiency. Meanwhile, as the inclined reinforcing pull strap 400 is provided with holes, the integrity of the inclined reinforcing pull strap 400 is destroyed, the tensile strength of the inclined reinforcing pull strap 400 is weakened, and the service lifetime is short.

[0033] In view of this, the designer provides a novel inflatable bed, which has a simple manufacturing process, a high processing efficiency, and a low manufacturing cost, and meanwhile, the inflatable bed has a high overall strength and a long service lifetime.

[0034] Referring to FIG. 1-FIG. 4, in the present embodiment, the novel inflatable bed includes a bed body 100 and at least one closed annular pull strap. The bed body 100 is provided with a main air chamber. The closed annular pull strap has two annular edges, and the closed annular pull strap is provided in the main air chamber, wherein the two annular edges are respectively welded to two adjacent bed walls of the bed body 100, so that the main air chamber is separated by the closed annular pull strap to form a central air chamber 103 and an edge air chamber. A weld seam formed by welding at least one of the two annular edges with the bed body 100 has at least one broken portion 001, so as to form a channel making the central air chamber 103 and the edge air chamber in communication at the broken portion 001.

[0035] It can be seen from the above description that in the novel inflatable bed provided in the present embodiment, the closed annular pull strap is fixedly connected to the bed body 100 by one-step welding molding process, and in the welding process, at least one of two annular edges of an annular cable-stayed partition plate is not completely welded to the bed wall of the bed body 100, that is, the weld seam formed after welding the annular edge to the bed wall is not a complete annular weld seam, but has at least one broken portion 001. The closed annular pull strap and the bed body 100 have a gap and form a channel at the broken portion 001, and the central air chamber 103 and the edge air chamber are in communication through the channel. In this way, the one-step welding process not only realizes the connection between the closed annular pull strap and the bed body 100, but also forms the channel making adjacent air chambers in communication, which process is simple and has high efficiency. During inflation, the description is made by taking that an inflation hole is provided in the central air chamber 103 as an example. Gas in the central air chamber 103 can enter the edge air chamber from the channel, to realize inflation of the central air chamber 103 and the edge air chamber at the same time, thus the inflating efficiency is high. After the inflation is completed, the closed annular pull strap functions as strengthening, edges of the bed body 100 are not easy to collapse, and the inflatable bed is comfortable to use and highly safe. Meanwhile, since the overall structure of the closed annular pull strap is not destroyed, the closed annular pull strap has strong tensile strength, is not easily damaged in use, and has a long service lifetime and a low use cost.
