| 20110158834 | BUILT-IN ELECTRIC AIR PUMP FOR USE IN INFLATABLE PRODUCTS - A built-in electric air pump mounted on an inflatable bed by heat binding or adhesion is provided, and includes a pump housing; an air duct conversion mechanism mounted in the pump housing; a cover assembly covering the pump housing; a switch assembly connected with the air duct conversion mechanism; an air valve assembly disposed on the bottom of the pump housing; and a power source device connected with the switch assembly and powering the air pump. The air pump receives power from combinations of power sources in four different modes, namely, dry batteries, a rechargeable battery pack assembly, a vehicle-mounted power source and an AC adapter which match one another, to drive the pump, thereby forming multiple power source configurations to drive the same set of air pump and enable the same inflatable bed to be used indoors as well as outdoors at any time. | 06-30-2011 |
| 20100247355 | BUILT-IN ELECTRIC AIR PUMP FOR INFLATABLE PRODUCT - The present invention disclosed a built-in electric air pump for inflatable product, including a housing, a panel cover, an impeller, a motor, an intake, an air valve orifice, an air valve and an air passage part forming a motor chamber, an impeller chamber and an air passage in the housing, wherein an air passage directional chamber is formed by the air passage part, which is the junction of the air passage, the intake and the air valve orifice; an air passage directional valve is mounted within the air passage directional chamber; a motor chamber's air inlet is located on the wall of the air passage directional chamber; and the air passage directional valve has a heat dissipation and pressure release outlet which is used for pressure release, air exhaust and heat dissipation during the inflation process and used for drawing-in cool air from the environment during the deflation process. The present invention has a simple structure. A heat dissipation and pressure release outlet is arranged in the passage directional valve, which results in good heat dissipation and prevents the inflatable product from exploding as excess inflation pressure. Furthermore, the additional seal assembly with double leakproof function prevents the airbed inflated with air from leaking for a long time. | 09-30-2010 |
