Abstract: An attachment member for engaging with different tire valves includes a tube having a pipe laterally secured on top. Two caps are secured to the ends of the pipe. Two couplers and two gaskets are engaged in the pipe for engaging with different tire valves. The gaskets each has a curved surface for engaging with a ball. The ball is rotatably engaged between the gaskets and secured to a block for coupling to a hand pump and includes an orifice for aligning with either of the apertures of the gaskets and for supplying pressurized air to the either of the tire valves.

Abstract: A handle includes a limiting member, a handle body, a switch member and a biasing member. The limiting member is adapted to connect with an air pump and has a limiting recess. The handle body is pivotally connected to the limiting member to change between a folded position and a use position, and has a slot. The switch member is pivotally arranged in the slot and has a restricting portion detachably engaged with the limiting recess. The restricting portion is engaged with the limiting recess when the handle body is in the use position, and is disengaged from the limiting recess as the switch member moved relative to the slot. The biasing member biases the switch member toward the outside of the slot.

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 ii 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 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 portable air pump includes an inflation assembly, a head seat pivotally connected to the inflation assembly, a pressure gauge disposed in the head seat, a connection assembly pivotally connected to the inflation assembly, and an axial member. The inflation assembly includes a cylinder and a piston rod moveable relative to the cylinder to compress the air inside the cylinder. One end of the head seat is provided with the containing groove, and another end of the head seat is provided with a pedal portion. The connection assembly is adapted to connect with an air-inflatable object. The axial member is mounted through the inflation assembly and the head seat and is connected to the connection assembly. The axial member is provided with an airflow channel communicating with the cylinder, the containing groove, and the connection assembly.

Abstract: A valve connector includes a connecting member, a threaded member, a joint member, and first and second connection assemblies. The connecting member is inserted into an axial hole of the threaded member to cause an abutting portion of the connecting member to enter into the axial hole. The joint member forms two threaded sections at two opposite ends thereof. The two threaded sections are alternatively detachably connected to a threaded portion of the threaded member so that a first seal ring of the first connection assembly and a second seal ring of the second connection assembly are alternatively removably abutted against the abutting portion for connecting a Schrader valve and a Presta valve.

Abstract: A pump head of an air pump includes a head including an outer body, a handle, and an end cap. The outer body includes a compartment extending therein. The handle is connected to a first end of the outer body. The end cap is connected to a second end of the outer body. A retaining device is received by the compartment and includes a seat actuated by the handle. An air seal ring is received by the compartment and is selectively compressed by the seat. The seat includes a cavity extending therein, at least one slot extending radially from the cavity and through the seat, and at least one retaining arm extending between two sides of the at least one slot and resiliently swingable. The air seal ring has an outer periphery section curved radially inwardly with respect to other periphery sections along a longitudinal length thereof.
