Abstract: A variable-pressure air pump includes a first cylinder with a first chamber and a second cylinder with a second chamber movably connected with one another. The second chamber fluidly communicable with the outside of the variable-pressure air pump selectively. A discharge device includes a connecting member and a switch movably connected with one another. The connecting member defines at least one discharge hole fluidly connecting with the second chamber. The switch has at least one flow guide portion and at least one blocking portion. The switch is movable between a first position in which the at least one flow guide portion is adjacent and opens to the at least one discharge hole and a second position in which the at least one blocking portion is adjacent to and blocks the at least one discharge hole.

Abstract: A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

Abstract: An inflating device includes an air pump, a valve engaging head, and a pushing apparatus disposed on the air pump and selectively engaging and disengaging the valve engaging head. The valve engaging head includes a main body, a connection assembly coupled to the main body and having a connection hole for a Presta valve and another connection hole for a Schrader valve, and a valve seat movably disposed in the main body. The connection assembly has a receiving hole and the valve seat is movably disposed in the receiving hole. The pushing apparatus selectively contacts and disengages from the connection assembly. The pushing apparatus has a pushing portion adapted to drive the valve seat. The pushing apparatus engaging the valve engaging head includes the pushing portion pushing the first abutting portion, thereby driving the valve seat toward the second connection hole.

Abstract: A relief device in air pump includes a main body defining an interior space and a discharge passage fluidly communicating with the interior space. The discharge passage is selectively closed and opened by a valve device. The valve device is movable in the discharge passage. The valve device includes a first sealing portion and a second sealing portion selectively engaging with the discharge passage. The valve device is movable between a first position in which one of the first and the second sealing portions engages with the discharge passage and a second position in which the other of the first and the second sealing portion engages with the discharge passage. The discharge passage has a length measuring from the first end to the second end thereof, which is smaller than a length which measures a separation distance between the first and the second sealing portions.

Abstract: An air pump includes a cylinder, a piston rod, and an upper cover. The cylinder forms an opening at a top end thereof and at least one retaining hole adjacent to the opening. The piston rod is configured to be movable within the cylinder and provided with a piston forming a conical lateral face at one end thereof. The upper cover has a top portion forming a hole for the piston rod to penetrate therethrough, at least one extension portion extended from the top portion, and at least one retaining portion extended from the extension portion. The least one extension portion has an abutting edge selectively abutted against the conical lateral face. The retaining portion is engaged with the retaining hole.

Abstract: An inflator valve connector includes a housing, a connection assembly, a valve seat, and a pushing member. The connection assembly is rotatably arranged in the housing and includes a first connection hole adapted to connect a Presta valve and a second connection hole adapted to connect a Schrader valve. The valve seat has a first abutting portion faced to the first connection hole and adapted to abut a lock nut of the Presta valve, and a second abutting portion faced to the second connection hole and adapted to abut a valve core of the Schrader valve. The pushing member removably contacts the connection assembly and has a pushing portion adapted to enter the housing via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the housing and to close to the second connection hole.

Abstract: A variable pressure air pump includes a first cylinder and a second cylinder movable relative to the first cylinder along a longitudinal axis. An air tube is mounted in the first and second cylinders. A mounting portion is integrally formed on a first end of the air tube. A first piston and a second piston compress air in the first and second cylinders. A connecting device is mounted to the first cylinder for coupling with an object to be inflated. An air escape device selectively seals a second chamber of the second cylinder to selectively compress the air in the second cylinder. A first check valve is mounted to the mounting portion of the air tube. A second check valve is mounted to the second piston.

Abstract: An air pump includes a pumping system, a storage tank, a discharge passage, and a valve. The discharge passage includes a first section and a second section wider than the first section. The valve is movable in the discharge passage. The valve, disposed in a first position, includes a first seal end disposed in the first section and abutting a periphery thereof and includes a second seal end disposed in the second section and abutting a periphery thereof. The valve, disposed in a second position, includes the first seal end disengaging from the first section and not abutting the periphery thereof and includes the second seal end disposed in the second section and abutting the periphery thereof. The first and second seal ends respectively have first and second cross-sectional areas. The ratio of the second cross-sectional area to the first cross-sectional area is at least 2 to 1.
