Abstract: Water leakage and damage to the electric motor of a diaphragm type pressurized pump are avoided by providing the diaphragm with integral hollow cylinders which are inserted through ladder holes of piston head pushing chunks and deformed into sealing engagement with the pushing chunks and their corresponding wobble plates by screws extending through the cylinders and threadedly engaged within corresponding threaded holes of the wobble plates.

Abstract: A compressing diaphragm pump having abnormal pressure preventing features for spray use has a hollow tubular air discharge assembly having a plunger body and compressed spring as well as an air passage pierced at the wall of the water exit port and an air discharge orifice pierced of the central top surface of the air discharge assembly for connecting with the plunger body. When air is mixed within the pressurized water, the resilient force of the compressed spring is bigger than the water pressure of the pressurized water. This allows the air mixed in the pressurized water to get into the air passage and pass the plunger opening of the plunger body via through pore, and is dispelled out of the upper hood via the air discharge orifice of the air discharge assembly.

Abstract: The present invention provides a discharge implement of reservoir for portable pressurized sprayer” comprising a discharging vent and a discharging hose. The discharging vent, which created in a vertical tucked buttress for a recessed sole of a portable reservoir, has an end exposed outwardly. The discharging hose has an end opening connected to the exposed end of the discharging vent and another end opening connected to a cylindrical discharging mount of a diaphragm compression pump respectively. If air is mingled in the compressed water, the air is immediately brought into the discharging hose and pass the discharging vent to flow into the portable reservoir with all damped moisture therein so that the damped moisture is completely eliminated without damped moisture remained therein. Thus, the drawbacks of harmfully affecting all parts therein and shortening service life for the portable pressurized sprayer incurred can be entirely avoided.

Abstract: A diaphragm type pressurized pump comprises a hollow cylinder formed on the top surface of each piston acting region of the diaphragm sheet. A piston head pushing chunk is disposed on the diaphragm sheet such that a ladder hole in the piston head pushing chunk receives the hollow cylinder. A fixing screw is driven via the center of the hollow cylinder into the threaded hole on each wobble plate. As a result of driving the fixing screw, the upper portion of the hollow cylinder expands thereby deforming and filling up the space between the bottom surface of the head of the fixing screw and the top surface of the ladder hole of the piston head pushing chunk, and thus preventing water from leaking and seeping into the motor of the pump.

Abstract: A group of genes including GhCIR1 from cotton (Gossypium hirsutum), and AtCIR1 and AtCIR2 from Arabidopsis thaliana promote shoot regeneration in plants even in the absence of cytokinin. In the presence of cytokinin, the genes significantly improve transformation efficiency. The genes can be used as an enhancer as well as a selectable marker of transformation in plants. The proteins encoded by the novel genes have a homeodomain (HD) at the N-terminus and a highly divergent domain at the C-terminus. The proteins share a common structural motif.

Abstract: A manufacturing method and structure of a heat exchanger for a bathing shower involves two plates welded together to form a passage for cold water. Hot water from the shower drips onto the upper plate and transfer heat to cold water flowing through the passage between the plates. The upper plate may be spot welded to the lower plate at bottoms of frustoconical indentations in the lower plate, the plates may sandwich an adiabatic layer, and/or the passage between the plates may be formed by pipes situated between the plates.

Abstract: In a piston valve in a compressing pump, a discharge base formed in the center of the piston valve has a planar shape having discharge spouts formed corresponding with each inlet slots. A 3-bladed anti-backflow plastic gasket covers the top of the discharge base such that each blade can block corresponding discharge spouts. As wobble wheels of the compressing pump push the diaphragm in turns, the water flow from each said inlet slot at each area will continuously run into each discharge spout at each area in said discharge base in turn so that each blade of the gasket moves up and down in turn as well, to achieve an open-and-shut effect of the discharge spouts. Therefore, drawbacks of leakage, pressure loss, or failure can be prevented, and the serving life of the gasket can be prolonged, improving the compressing and discharging efficiency of the pump.

Abstract: The present invention provides a shock damper for outlet pipe of diaphragm pump comprising a shock damper pod including an intake jointer, an outtake jointer, a stroke cavity and a cap receptacle, a damping block, a damping elastomer and a damper cap. After screwing the intake jointer into the water outlet orifice of the pump upper hood with motor power on, pressurized water come from high-pressured chamber will flow into water intake channel of shock damper pod to impact damping block in periodically pulsatile manner; Meanwhile, resilient force of compressed spring will offset the periodic impact of pressurized water in counteracting damper manner so that pressurized water will become a steady flow without any pulsation. Accordingly, the shock damper not only can obviate the shock and vibration for the outlet pipe but also can reduce the shock and annoying noise in the pump upper hood.

Abstract: The present invention provides a leakage-proof contrivance for upper hood of diaphragm pump by modifying the vertical wall of the lower tiered brim in the tiered cavity of the conventional pump upper hood into a sloped wall. Thereby, when stacked assembly of sealing collar gasket, piston valve and diaphragm is inset into the tiered cavity of the pump upper hood in closely attachment manner, the sealing collar gasket will be slantwise squeezed and vertically deformed to produce normal outwards stress in both upwards and downwards manners. Thus, the sealing collar gasket can respectively inset in the pump upper hood and piston valve in much more closely attachment manner to block and prevent the pressurized water from leaking out of the diaphragm pump.

Abstract: The present invention relates to an “improved piston valve for diaphragm pump” features that each of water discharge base and water discharge base has a top camber concave surface with orientating hole center and orientating hole center as lowest point respectively; After anchoring anti-backflow plastic gasket into water discharge base, a gap is formed between bottom surface of anti-backflow plastic gasket and top camber concave surface of water discharge base; Likewise, after anchoring each piston slice into each corresponding water inlet port, a gap is formed between bottom surface of piston slice and top camber concave surface of water inlet port; By functions of foregoing gaps, the overall compressing efficiency is substantially enhanced because both sucking forces of anti-backflow plastic gasket and piston slice are further increased by reciprocal actions of piston pusher.
