Abstract: An air bed with a stable supporting structure comprises a periphery sheet, a top sheet, and a bottom sheet. A middle sheet separates an air bed into an upper air-chamber and a lower air-chamber, an outer extending strip separates the upper air-chamber into a peripheral air-chamber and an upper main air-chamber, a first set of extending strip is provided in the upper main air-chamber, a second set of extending strip, which is welded with the middle sheet and the bottom sheet, is provided in the lower air-chamber, and an oblique extending strip is provided around the periphery of the second extending strip and is welded with the periphery sheet and the bottom sheet to separate the lower air-chamber into a lower main air-chamber and a peripheral auxiliary air-chamber.

Abstract: A built-in electrical inflating and deflating pump for inflatable product includes an air-pump, a panel, a housing and a base. The inlet of the air-pump is provided with an inlet hole communicated with external space and an inlet hole communicated with an internal space of an inflatable product respectively, the outlet of the air-pump is provided with an outlet hole communicated with external space and an outlet hole communicated with the internal space respectively as well. The first valve sheet is provided between two inlet holes, the second valve sheet is provided between two outlet holes, and each of these two valve sheets is moved between the respective corresponding inlet holes or outlet holes under the control of the valve pole and the valve sheet transmission-control device to open or close their respective corresponding inlet holes or outlet holes.

Abstract: A flexible swimming pool comprises a pool wall, a base sheet and an inflatable ring, the sidewall is a continuous sidewall, that is, there is no welding seam in a vertical direction from the top, on which the inflatable ring is connected, to the bottom, a plurality of notches are cut out in the lower edge of each continuous sidewall, the sidewall is connected directly with the base sheet, the pool wall formed of the sidewalls connected into a loop is connected with the inflatable ring at its top to support the pool wall in a vertical direction, and a sidewall bottom ring folding inwards which is formed by overlapping and bonding the material sheets of both sides of each notch is connected directly with the base sheet. The advantage of the present invention is that it has reduced the welding seams at the lower edge of the sidewall to make the strength of the pool increased and the probability of water-leaking decreased greatly.
