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.

Abstract: The present invention provides an air discharge implement for a portable pressurized sprayer comprising a cylindrical main body of discharging duct, an external hood jacket, a conical moving plug and a compression spring. 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.

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.

Abstract: The present invention provides a “compressing diaphragm pump having automatic air expelling and pressure abnormal-preventing features for spray use” that comprises a hollow tubular air discharge assembly, having a plunger body and compressed spring disposed therein as well as a air passage pierced at the wall of the water exit port and a air discharge orifice pierced of the central top surface of the air discharge assembly for connecting with the plunger body; When air being mixed within the pressurized water, the resilient force of the compressed spring being bigger than the water pressure of the pressurized water. Thereby, the air mixed in the pressurized water will get into the air passage and pass the plunger opening of the plunger body via through pore, and finally dispelled out of the upper hood via the air discharge orifice of the air discharge assembly.

The flowing device has a propeller wheel which is driven to rotate by a flow of water and has a magnetic element. The light induction unit has an infrared beam emitting member, an infrared beam detector and a magnetic induction rotator. The magnetic induction rotator is driven by the rotating magnetic element of the propeller wheel to rotate and thus its rotation is in synchronization with the rotating movement of the propeller wheel of the flowing device. When the magnetic rotator rotates, it intermittently blocks off the path of the infrared beam emitted continuously by the infrared beam emitting member and the infrared beam detector receives intermittent infrared light The frequency of reception of such intermittent infrared light by the infrared beam detector is proportional to the flow rate.
