Provided is 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.

An inflatable product includes an inflatable body and a supplemental layer. The inflatable body includes a first wall and a first auxiliary sheet fused with each other. The supplemental layer is configured to cover the first wall and is fixed to the first auxiliary sheet of the inflatable body by sewing and/or gluing.

A method for installing a universal air handler for a building air conditioning system includes installing a compact outdoor cabinet having a blower and separate intake and outlet chambers separated by an evaporator core. Cool and return air ducts from the building couple to each chamber. Return air drawn by the blower into the return air chamber passes across the evaporator, then through the blower and out through the cool air duct. Coolant lines couple the evaporator to a nearby stand-alone condenser/compressor unit. In one embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the footprint of the combination. In another embodiment, a manifold couples permanently to the building air ducts and releasably couples to the cabinet. The universal air handler easily decouples from the manifold for transportation and maintenance. The manifold may be installed in various locations around the building, including on the roof.

An inflatable bed with a mesh-shaped inclined diaphragm includes a side panel, the mesh-shaped inclined diaphragm and two face layers symmetrically arranged, a first end of the side panel is connected to a periphery of a first face layer of the two face layers, a second end of the side panel is connected to a periphery of a second face layer of the two face layers, a first end of the mesh-shaped inclined diaphragm is connected to the side panel, and a second end of the mesh-shaped inclined diaphragm is connected to one of the two face layers.

A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.

An air bag module of inflatable mattress is disclosed. The inflatable mattress is provided with a lining for the air bag module to be placed therein, and a resilience supplying module being placed in the lining and resting on the air bag module. The air bag module includes at least one air bag unit. The air bag unit is provided with an air distribution layer and a hardness adjustment layer connected with the air distribution layer while located between the air distribution layer and the resilience supplying module. In the air distribution layer, air is inputted into each distributing air bag equally via intercommunication of distributing air bags, such that air from the distributing air bags is consistently received by each supporting air bag of the hardness adjustment layer. Thus, the problem of uneven surface of bed due to non-uniform inflation in the conventional structure is solved.

A mattress with adjustable hardness comprises at least one resilience supplying module, at least one air bag module and a lining provided for the resilience supplying module and the air bag module to be placed therein. The lining is provided with a plurality of lattice-like units, each lattice-like unit defining a mounting space therein. The resilience supplying module is provided with a plurality of elastic bodies respectively provided in one of the mounting spaces. The air bag module is provided with a plurality of air bag units respectively provided in one of the mounting spaces. In this case, the air bag units may be inflated consistently, and the expanded volume of each of the air bag units after inflation may be limited to be uniform by the corresponding lattice-like unit. Thus, the problem of incapability of being kept evenness after inflation in the conventional practice is solved.

The inflatable pad includes an inflatable frame having a length and width that defines a pad area suitable for supporting a person lying thereon. A plurality of internal support members are configured to support the weight of a person lying thereon and elevate the person above the ground. The inflatable pad includes non-supporting regions that require less fill volume than regions that support primary support regions such as the hips and shoulder.
