Abstract: An ozone-water generator comprises a machine body, an ozone generator, a gas-liquid mixer and a light-controlled switch. The machine body is employed for holding the ozone generator, the gas-liquid mixer and the light-controlled switch. The ozone generator is connected to the gas-liquid mixer. The gas-liquid mixer is connected to the light-controlled switch. The light-controlled switch comprises a tube, two circuit boards, a movable valve and an elastic device. The movable valve is forwardly and backwardly shiftable within the tube. When the movable valve is shifted by the force of water current, two light-controlled devices on the respective circuit boards can be electrically conducted to form an electrical signal for actuating the ozone generator and thereby mixing the ozone and the liquid. The movable valve is so extremely light in weight that an extremely small force of water current is sufficient to shift the movable valve.

Abstract: An automatic oil pump includes a drive chamber, having a reciprocal driving device, and an oil chamber, having a sucking device, located on two sides of a main body. The reciprocal driving device has a piston unit having a valve chamber at its center and a balance valve and is pushed by a spring. The drive chamber has grooves on its inside wall. The piston unit has two channels, allowing air to flow into the valve chamber past two sides of the piston unit. On the piston unit is a driving rod. The driving rod penetrates into the main body and reaches into the oil chamber. A hermetic cover and a movable piston are attached to an end of the driving rod. On the wall of the piston are pluralities of through holes. The reciprocal driving device drives the piston in the oil chamber to move reciprocally, so oil is sucked into and out of the oil chamber continuously. Thereby, oil sucking speed and volume are upgraded to save time and labor, and oil pumping efficiency is enhanced.

Abstract: A negative ion hairbrush mainly comprises a comb holder and a handle which are folded and pivoted in overlapping manner. The comb holder contains a plurality of flexible or retractable combs and the handle embraces a negative ion generator and a negative ion outlet at the pivot joint directing the anion energy from the generator flowing toward the combs when the comb holder and the handle are in opening position. While the comb holder and the handle are in folded position, the negative ion outlet is exposed and the anion energy continues flowing outward so the negative ion hairbrush is used as the hairbrush and as the air purifier. When used as a hairbrush, the negative ion energy will neutralize the cation charge to prevent the hair cell from decaying and the hair from falling off.

Abstract: An air-purifying cap comprises a main body and an anion generator. The main body has a groove at the front cap edge to accommodate the anion generator. The anion generator is a box incorporating a high voltage circuit and a battery, or a box attached with a solar energy collecting plate, so the battery or the solar energy plate can supply DC power to high voltage circuit and allow the internal discharge electrode for high voltage discharge to produce huge amount of anions that output from the box bottom. The released anions will decompose airborne virus and purify the air quality for human respiratory system. It provides an instant measure to effectively inhibit the spreading virus.

Abstract: An ozone water foot massager includes a container disposed on top of a water compartment and having a recess for receiving feet of users. A tubular member is received in the water compartment and coupled to a nozzle, an ozone generator is coupled to the tubular member for supplying an ozone to a neck of the tubular member. The fluid may flow fastener through the neck of the tubular member, for drawing and mixing the ozone and the fluid with each other into an ozonized water, and for supplying the well mixed ozonized water to clean the feet of the users.

Abstract: The present invention relates to an anti-reverse structure of a continuous pneumatic oil feeding gun. An anti-reverse valve is mounted in the gun bore and includes a valve body formed with an annular groove communicated with the oil supply hole, an oil inlet hole connected between the annular groove and the bore of the bore body, and an oil outlet hole connected between the bore of the bore body and the oil supply hole. Each of the oil inlet and outlet holes is formed with an enlarged receiving space for receiving a ball. The enlarged receiving space is formed with a reduced catch portion to prevent from falling of the ball.

Abstract: The present invention relates a jack assembly that may be lifted rapidly. A secondary shaft is mounted in a lifting column, and has a distal end screwed into an axial hole in the base. The main oil path is provided with a lower ball and an upper ball, and has a first oil hole connected to the oil hole of the secondary shaft, and a second oil hole connected to the inner oil chamber. The hydraulic oil pushes away the lower ball to flow through the first oil hole into the secondary shaft, so that the lifting column that has not worked may be lifted rapidly. The lifting column may work to increase the pressure of the hydraulic oil which flows through the second oil hole into the inner oil chamber, so that the lifting column may have a sufficient lifting force to lift an object.

Abstract: An ozone-generating faucet includes an ozone generator mounted on a mixer tube between a water supply tube and a spout, a water intake valve connected between the mixer tube and the water supply tube to control supply of water from the water supply tube to the mixer tube, an electromagnetic valve controlled to close/open the water intake valve, the ozone generator including an ozone-generating unit, a control circuit board, and an ozone supply tube connected between the ozone-generating unit and the mixer tube, the control circuit board being controlled by control switch to turn on the ozone generator and open the electromagnetic valve, enabling ozone to be supplied to water running through the mixer tube.

Abstract: The present invention relates to a grease gun having an automatic continuous feeding device, including a gun body, a piston chamber, a piston, a spring, a barrel chamber, a plunger, a container, a switch valve, and a trigger. Thus, the piston may be moved reciprocally and automatically by pressing the trigger successively, so that the grease in the container may be ejected outward continuously without having to compress and loosen the trigger repeatedly, thereby facilitating the user operating the grease gun.
