Abstract: This invention provides a high pressure gas cylinder which comprises a storage tube, an inlet cover, an inlet junction, an outlet cover, an outlet junction, an anti-pressure plate, a solenoid valve, an inner check valve and an outer check valve. The storage tube is provided with longitudinally shaped join troughs distributed evenly on its inner surface. The assembly of the system starts by inserting an anti-pressure plate into each of two openings of the tube, followed by fastening the through holes on the inlet and outlet covers to the corresponding join troughs with the screw bolts, which makes all the joints enclosed by the tube, and makes the closure more solid. The outlet cover is provided with an inner check valve and an outer check valve at its interior and exterior respectively, which substantially avoid all kinds of erroneous operations resulting in the abnormal guiding of the high pressure gas in flowing back into the tube.

Abstract: A pressured drinking water dispenser includes a control device and an air and water connector inserted in the cap of a tank. The control device and the water connector are mutually connected with an air tube and a water tube between. The control device has a circuit board, an air pump and an electromagnetic valve. The air pump and the electromagnetic valve are mutually connected with an air joint and an air tube. The air and water connector is inserted in the cap of a tank, having an air joint and a water joint respectively connected with the air tube and the water tube. When the air pump is electrified to pump air, with the electromagnetic valve electrified to be closed, the air may flow orderly through the air route into the tank to become highly compressed air to force the drinking water therein to flow through the water route into the water container in the dispenser body.

Abstract: A pen-shaped tire pressure gauge includes a hollow body having one end formed with a pressure measuring head and the other end formed with an open end and its interior formed with an accommodating space. The pressure measuring head is formed with an air intake passageway communicating with the accommodating space and has its outside fitted with a metallic protecting ring. A scale rod is received in a coiled spring and they both are positioned in the hollow body. The coiled spring is fitted with a piston at the upper end, and the scale rod is fitted with a stop ring and a stop sleeve around the lower end. A fixing cap is combined with the open end to prevent the components inside the hollow body from dropping out, strengthening the pressure measuring head to prolong its service life.

Abstract: A control device for a ball-hurling machine includes a ball-hurling machine and a control plate. The ball-hurling machine has a body, a receiver and a display provided in the body. The transmitter controls the power of the machine, the mode of balls shot out and the display to show various images of different colors according to the modes of balls shot out. The control plate is separated from the ball-hurling machine, placed at a hitting area, having a transmitter and plural press buttons for control the transmitter to send out various signals to the receiver of the ball hurling machine. Then the ball-hurling machine shoots out balls according to the signal received so that a hitter himself can control operation of the control device to decide the mode of balls hurled out of the machine to get hitting training.

Abstract: A container for liquid oil of energy includes a container body, a top cover and a bottom cover. The container body is made of aluminum squeezed into a tubular shape with a hollow interior and provided with plural vertical support posts and a vertical projection fitted with a gasification box. The top cover and the bottom cover are respectively fitted on the top edges and the bottom edges of the support posts. The top cover is fixed with a stop valve and an air filling pump functioning to turn off power. Then, the bottom side of the stop valve is connected with an air intake pipe extending into the gasification box. The oil container of such design is easy in manufacturing, possible to lower manufacturing cost and capable to permit the oil and air inside mixed completely to elevate the degree of gasification and density of oil gas.
