Abstract: A pump assembly is provided for use with an inflatable product. The inflatable product has a chamber having an air inlet and an air outlet. The pump assembly has a pump unit that is positioned inside the chamber for inflating and deflating the chamber, the pump unit having at least one motor that is operatively coupled to a first blower and a second blower, with the first blower fluidly coupled to the air inlet and the second blower fluidly coupled to the air outlet. The chamber is inflated by intake of air through the air inlet to the first blower and then into the chamber, and the chamber is deflated by drawing air from the chamber to the second blower and then out of the chamber through the air outlet.

Abstract: A pump unit includes a pump housing having a valve assembly positioned on a wall thereof and adapted to be coupled to an inflatable device, and an air control assembly that is housed inside the pump housing. The air control assembly includes an impeller section that houses an impeller, and has an air inlet and an air outlet. The air control assembly further includes a motor housing that houses a motor, the motor housing having an air vent that communicates the interior of the motor housing with the air inlet and the air outlet, and a vent opening that communicates the interior of the motor housing to the environment. The air outlet is aligned with the valve assembly when the pump unit is operated in the inflation mode, and the air inlet is aligned with the valve assembly when the pump unit is operated in the deflation mode.

Abstract: A machine and method for making an inflatable product is disclosed. The inflatable product has an upper layer and a lower layer. The machine having a presser, a welder press frame, an upper flat plate secured to the presser, and a lower flat plate secured to the welder press frame. Each flat plate has a plurality of slide rests, each slide rest having a plurality of detachable plates positioned along the slide rest. A lower layer of material is placed on top of the lower flat plate and on top of the plurality of detachable plates on the lower flat plate. A plurality of die assemblies is positioned on top of the lower layer of material in a manner where each die assembly is aligned with a corresponding slide rest. Then, an upper layer of material is placed on top of the die assemblies and below the upper flat plate. The upper flat plate is pressed on top of the upper layer of material to perform heat welding.

Abstract: An electrical charging system includes a charging socket and a standby battery product. The charging socket has a socket casing, and a power input interface on the socket casing and electrically connected to a first conductive contact that extends above the socket casing. The standby battery product has a battery casing with a battery housed inside the battery casing, the battery casing further including a conductive pin and a second conductive contact, with the conductive pin and second conductive contact electrically connected to the battery. When the battery casing is placed on top of the socket casing, the conductive pin is aligned with, and contacts, the first conductive contact, creating a charging path that is defined by the power input interface (which receives external power), the first conductive contact of the socket casing, the conductive pin of the battery casing, and the electricity storage unit of the battery product.
