Inflatable Bed

Abstract

The present disclosure provides a novel inflatable bed, which relates to the field of articles for daily use. The novel inflatable bed comprises a bed body and a closed annular pull strap. The bed body is provided with a main air chamber. The closed annular pull strap has two annular edges, the closed annular pull strap is provided in the main air chamber, the two annular edges are respectively welded to two adjacent bed walls of the bed body, so that the main air chamber is separated to form a central air chamber and an edge air chamber. A weld seam formed by welding at least one of the two annular edges with the bed body has at least one broken portion, so as to form a channel making the central air chamber and the edge air chamber in communication at the broken portion. Through the high-frequency heat-sealing process, the closed annular pull strap and the bed body are molded in one step, in which not only a fixed connection between the closed annular pull strap and the bed body is achieved, but also the channel for making the edge air chamber and the central air chamber in communication is formed, which process is simple, and has high processing efficiency and low processing cost. Meanwhile, the overall structure of the closed annular pull strap is not destroyed, and the closed annular pull strap has a strong tensile property, a long service lifetime, and a low use cost.

What is claimed is:
