Description

TECHNICAL FIELD

The present disclosure relates to the field of articles for daily use, and particularly to a novel inflatable bed.

BACKGROUND ART

The inflatable bed refers to a bed that expands and becomes large in volume after being inflated. The inflatable bed is flexible and elastic, is not easy to deform, has relatively high comfort in use, and can discharge gas when not in use. The inflatable bed has a small volume, can be folded and stored, and is convenient to carry and transport. At present, since a mattress with a single air chamber has a simple production process and is easy to manufacture, most of the inflatable mattresses on the market have a single air chamber, and an inflator pump used for the mattress with a single air chamber also has a single air chamber, wherein the entire air chamber inside the mattress is inflated and deflated during inflation and deflation. However, the inflatable bed with a single air chamber is easy to collapse at edges, and use effect is not ideal. Inflatable bed with multiple air chambers emerges in the market. A relatively common inflatable bed with multiple air chambers is an inflatable bed with three air chambers, in which an inclined pull strap is provided, and a bed body is strengthened through the inclined pull strap, improving the stability.

According to the inventor's research, the existing inflatable bed with multiple air chambers has the following shortcomings:

the multiple air chambers are in communication with each other by means of through holes provided on the inclined pull strap, in this way, in the process of manufacturing the inflatable bed, the inclined pull strap needs to be first connected to the bed body, and then the through holes are provided on the inclined pull strap, which process is cumbersome and has low efficiency and a high cost; moreover, due to the configuration of the through holes, the structure of the inclined pull strap is destroyed, so that the tensile strength is weakened, and the service lifetime is short.

SUMMARY

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.

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.

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.

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.
