Patent number: 8641391Abstract: 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.Type: GrantFiled: December 28, 2010Date of Patent: February 4, 2014Assignee: Foshan Shunde Xinshengyuan Electrical Appliances Co., LtdInventor: Erjian Pan

Patent number: 8480359Abstract: A blower comprising: a snail-shaped base, a snail-shaped cover, blades and a motor, wherein the snail-shaped base and the snail-shaped cover form a exhaust channel, the blades are horizontally provided in the exhaust channel, the snail-shaped cover above the blades is provided with an air intake channel formed by a motor mounting chamber and a motor cover, and the motor is vertically disposed in the air intake channel and connected to the blades therebelow. The blower is structurally scientific and concise. When the blower operates, air is taken in and provides effective heat dissipation for the motor, and there is a sufficient distance between the motor and the ground surface, and waterproof designs of the sealed capacitor junction box and both ends of the motor can perform an excellent waterproof function.Type: GrantFiled: February 8, 2010Date of Patent: July 9, 2013Assignee: Foshan Shunde Xinshengyuan Electrical Appliances Co. Ltd.Inventor: Erjian Pan
