摘要： A safety syringe includes a barrel which has a hollow passage inside and is coupled with a barrel cover. A push rod has a distal end coupled with a rubber ring to form a close contact with the hollow passage in a slidable manner. A driving module has an inner detent member, a piston seat and a piston rubber ring held in the barrel cover. The push rod is movable forwards to push the inner detent member and the piston rubber ring of the driving module forwards to make a cut surface at one end of the push rod to hit one end of a first stem of the needle mount to be broken and separated so that continuous moving forward of the push rod causes instant release of air pressure inside to retract the needle mount in a holding chamber of the push rod to safely hold a needle after injection.

摘要： A safety syringe includes a barrel, a push rod, a driving module, and a needle mount. The barrel includes a hollow passage and a barrel cover, and the push rod includes a pad disposed around a distal portion and pushed tightly along the hollow passage of the barrel, and the barrel cover includes a plunger, a driving module of a piston pump, and a needle mount having a cut surface at the piston pump, such that the distal portion of the push rod pushes the plunger to move forward, while the cut surface of the distal portion and the cut surface of the needle mount are pressed to separate with each other, and the plunger continues moving forward to offset the air pressure therein, so as to retract the needle mount into a push rod accommodating cavity to accommodate the needle safely after an injection is taken place.

摘要： An apparatus for mixing and proportioning oil and water comprises an upper lid, a first chunk member, a holder, a second chunk member and a base. The first chunk member and second chunk member have respectively an oil inlet, an oil-water mixture outlet and a water outlet that are connected with one another to receive and discharge oil and water. The first and second chunk members have respectively two oil flow gears and two water flow gears that engage with each other to control oil and water entering ratio to achieve optimal combustion efficiency. In the base, a located water regulation valve is adjusted to buffer water intake ratio responding to internal pressure alterations. The water regulation valve forms a buffer passage allowing different ratios of water to flow to the water in/out passage so that an improved oil-water mixture is achieved to enhance combustion efficiency of the combustion system.

摘要： An oil water mixture heating apparatus comprises a metal outer barrel with a helical trough formed inside, a metal inner barrel held in the metal outer barrel to form a helical passage with the helical trough, a first and a second guide cap coupled on two sides of the metal outer and inner barrels, a first and a second seal cap coupled respectively on the first and second guide caps, a first and a second holder fixedly located on outer sides of the two seal caps and an electric heater encasing the metal outer barrel. When combustible oil or oil water mixture enters the helical passage and are heated by the electric heater, the oil or oil water mixture also is constantly blended in the helical passage so that it is heated rapidly to a required temperature and forms a finer oil water mixture.
