With simple structure, it is easily fabricated by traditional extruding method without welding process and related welding technician. Thereby, selling price is reduced with marketing competitiveness because overall manufacturing cost is decreased so that the purchasing intention of the consumers is spurred. Thus, it is not only favorable to promote and penetrate marketing range and depth but also valuable to achieve energy saving and carbon reducing effect.

Abstract: The present invention provides a vibration reducing device for pump cover body of water shut-off diaphragm pump comprising a hood cover mount and a pump cover body with a containing pit, which orderly accommodates a plastic elastic membrane disk, an obstructing baffle and a compressed spring therein. The plastic elastic membrane disk includes a downward central flow directing buffer, which can insert into a flow directing compartment in the containing pit when the hood cover mount docks with the pump cover body. The flow directing buffer can not only absorb the direct impacting momentum of pumped high pressurized water to the surrounding internal wall of the flow directing compartment but also redirect the random impacting direction of the high pressurized water. Thus, the vibration of the pump cover body with annoying noise created by the impacting momentum of the high pressurized water is deleted.

Wherein the main body of hollow discharging duct includes a cylinder bore, a cylindrical discharging mount for containing conical moving plug, and an air passage interposed between hollow discharge chamber and cylinder bore. The external hood jacket is a hollow holder to contain compression spring. The conical moving plug includes a top cone and a planar base with plural footing legs so that a water flow gap is created between the planar base and the air passage at the cylinder bore. If the present invention is properly connected to a water outtake hose of a portable pressurized sprayer, either no air or certain air mingled in the compressed water, it can achieve the air-discharging effect completely.

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.

Thereby, purchasing intention of consumers is increased in consequence of satisfaction of the purchasing ability. Thus, not only the speed and range of the promotion is benefited, but also the environmental protection in energy saving and carbon reducing effect is expedited.

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.
