Abstract: An oxygen generator, including an upper casing, a base and a lower casing, has a large opening on both sides of the base for installing a molecule tube whose upper and lower plugs are inserted and positioned into engaging slots of the upper and lower casings respectively. An air pump is installed at the bottom of the lower casing and has a motor to drive a cam to drive high-pressure air into the molecule tube through a flow channel and the lower plug of the lower casing. High-pressure oxygen produced after the action of the molecular sieve material passes through flow channels inside the upper plug and the upper casing and remains in the oxygen storage tank. During use, high-pressure oxygen is outputted from an oxygen output regulating valve, converted by an oxygen output solenoid valve, and discharged from a locking slot of the upper casing.

Abstract: A quick release pipe connection includes a first connector and a second connector detachably combined with the first connector. The first connector includes a first connector seat, a first connecting member, a locking member, a limit pin, a first support member, a first elastic member, and a first stop member. The second connector includes a second connector seat, a second connecting member, a second support member, a second elastic member, and a second stop member. Thus, the first connector is combined with the second connector by inserting the second connecting member into the first connecting member, and the second connector is detached from the first connector by pressing the press portion of the locking member, so that the pipe connection is assembled and disassembled easily and rapidly.

Abstract: A filter pump for a pool includes, a motor, a filter, a water intake connecter and a water outlet connecter for combining water pipes. The water intake and outlet connecters are respectively fixed with a connector having male threads outside and a recessed stepped surface inside to make up a receiving space between the connector and the water intake or the water outlet connecter. The water pipe has its end formed with two annular projecting ribs for fitting a rotatable locking cover with female threads therein. After the water pipe is fitted with the water intake or the water outlet connecter, the locking cover is threadably mounted on the connector, letting the water pipe inserted in the receiving space and closely pressed by the locking cover.
