Abstract: An inflatable mat structure includes a mat. The mat includes an upper covering layer, a lower covering layer, and a plurality of blocking layers horizontally disposed between the upper and lower covering layers. The blocking layers pass through a plurality of longitudinal connecting members to be positioned at different positions. The blocking layers are partially wavy through the structural characteristics of the longitudinal connecting members, and the interior of the mat has a plurality of layered spaces formed by the blocking layers, so that the mat can reduce the possibility of air convection, so as to block air convection and prevent temperature radiation.

Abstract: A portable mat capable of blocking air convection and temperature radiation is disclosed. The portable mat is an inflatable mat, and includes a first outer covering layer and a second outer covering layer that are connected by a plurality of connecting members each in the form of a thin and light ring. Side pieces of the connecting members each have different widths according to high and low positions. A plurality of blocking layers of a blocking unit is fitted on the connecting members. The block layers have openings with different widths. The openings of the blocking layers are different in size corresponding to the different widths of the connecting member, so that the blocking layers are positioned at different heights to form a plurality of spaced space inside the mate, thereby blocking air convection and reducing temperature radiation.

Abstract: A valve nozzle structure for an inflatable cushion includes an outer body, an inner body, and a diaphragm member. The diaphragm member is assembled in the inner body. The inner body is assembled in the outer body. The valve nozzle structure is able to provide one-way inflation with an automatic check function and deflation. The outer body further includes a holding plate configured to release the sealing state of the diaphragm member. Thus, the valve nozzle structure can achieve an automatic and continuous deflation function. The inner body is detachably connected to the outer body, which is beneficial for maintenance and replacement of the parts.

Abstract: An improved structure of automatic pressure adjustable air bed mainly includes an air mattress, an air pump, and air pipes arranged therebetween, as well as a control system disposed on the air bed. The control system includes multiple pressure sensors disposed on the air mattress for acquiring pressure signals, and a main control unit for controlling actions of the air pump or electrical controlled valves thereon, thereby achieving the automatic adjustment of firmness of the air mattress.
