Abstract: A bidirectional air pump to selectively inflate or deflate an inflatable object has a housing, a pump assembly and a motor. The housing has a controller cover, a pump cover, and a motor cover. The pump assembly is mounted inside the housing and has a centrifugal pump, a binary supply/discharge valve assembly, a selectable check valve assembly and a valve controller. The motor is mounted inside the housing. The valve assembly and the motor cooperate to pump air into or draw air out of an air mattress or inflatable sofa.

Abstract: A compact water filter includes a housing, a filter and a water pump. The housing includes a bottom container and a pump casing. The bottom container has a top cavity and a water inlet communicating with the top cavity. The pump casing is mounted on the bottom container to cover the top cavity and has a water discharge port. The filter is mounted and held in the top cavity of the bottom container to remove contaminants from incoming water. The water pump is mounted in the housing to pump water into and out of the water filter through the water inlet and the water discharge port. Consequently, the water filter holds most of the pool water in the bottom container to lower the center of gravity of the water filter to keep the water filter from overturning when the water filter is operating.

Abstract: A control valve includes a horn-like body and a seat with an interior surface mounted on the rear. A secondary outlet, primary outlet and inlet are defined through the seat. Two hollow poles are formed at the interior surface of the seat and two first resilient members are mounted respectively in the hollow poles. A cover is mounted in the body and has two rods mounted in the hollow poles and abutting the first resilient members. Two shafts are formed in the cover and aligned respectively with the secondary outlet and primary outlet. Two valve disks are formed respectively at distal ends of the shafts and respectively align with the outlets. Two buttons are mounted on an outer surface of the cover, and each has a barb to selectively engage a recess defined in the horn-like body.

Abstract: A bidirectional air pump assembly includes a pump mounting case, a valve and an air pump. The pump mounting case is mounted in an inflatable object and has a valve mounting hole. The valve is held in the valve mounting hole and includes an adapter with a valve port and a valve disk. The valve disk is attached to the adapter and has a disk body and at least one disk stop protruding from the disk body. The air pump is detachably mounted in the pump mounting case and connects to the valve port. Therefore, the air pump draws air out of the inflatable body through the valve port and a gap caused by the at least one disk stop abutting the air pump, which keeps the disk body from completely closing the valve port.

Abstract: A nozzle structure has an air pump casing to receive therein the air pump and provided with an outlet defined through a bottom face of the air pump casing and a resilient plate detachably engaging with a peripheral edge defining the outlet of the air pump casing via a guiding element such that air pumped by the air pump is able to push the resilient plate away from the outlet when air is blowing out of the air pump casing and an air pump axle extending out from the air pump is able to push the resilient plate away from engagement with the peripheral edge of the outlet to allow air to flow into the air pump casing.

Abstract: An electric air blower includes a housing being composed of two symmetrical semi-housings. Each semi-housing has multiple feet formed at a lower side thereof, multiple notches respectively defined between the feet, multiple air inlets defined at a bottom plate thereof, a middle plate formed at a middle portion thereof, an upper plate formed at an upper portion thereof, and multiple air outlets defined through a top surface thereof. An air impeller is mounted between the bottom plates and the middle plates of the semi-housings. A motor is mounted between the middle plates and the upper plates of the semi-housings. An output axle of the motor extends downwards for driving the air impeller. A circuit board is installed in the housing and electrically connected with the motor. Thus, an inflatable toy fastened on the air blower can be continuously inflated by the electric air blower to attract passers-by.

Abstract: An air-cushioned bed assembly includes an air bed with a concave space defined in a side face thereof, a casing received in the concave space and securely connected to the side face of the air bed. The casing has a body with a U-shaped cross section, a through hole defined in a side face of the body and a cover foldably connected to a circumference defining the through hole. An air blower is detachably received in the body of the casing and has an inlet and an outlet corresponding to the through hole of the body. A securing device is securely formed in the body to selectively retain the air blower inside the casing. Activation of the air blower facilitates air flowing into the air bed via the through hole, which folds the cover.

Abstract: A valve used for an inflatable article includes a valve body and a male connector. The valve body has a rear hollow portion, a female connector attached to the rear hollow portion, and a spring-loaded valve core movable therein. The male connector has a first tubular end and a second tubular end, and the second tubular end is dimensioned to be snugly plugged in the female connector to move the spring-loaded valve core backward. Furthermore, the female connector of the valve body defines a pair of L-shaped slots, while the male connector is formed with a pair of bayonet fittings adapted to be held in the L-shaped slots after the second tubular end is plugged, thereby allowing the male connector to be fastened to the female connector and hence to the valve body in a quick-detachable manner.
