    Abstract: The invention discloses an all-plastic spray device, comprising a handle, an environmentally friendly cross-arm plastic spring, a positioning seat, a nozzle mechanism, a hexagonal plug, a piston mechanism, an environmentally friendly plastic upper spring, an environmentally friendly plastic lower spring, a plastic ball, and a pump body. The invention adopts the design of two-stage elastic element. Both the environmentally friendly plastic upper spring and the environmentally friendly plastic lower spring are made of plastic materials, which can well replace the metal spring. The two-stage elastic element also has a significant improvement in the pressing feel. In addition to being suitable for conventional liquid use, it is also very suitable for the use of solutions that are prone to corrosion with metal parts. The invention greatly facilitates people's daily use and maintains life, health and safety in people's daily use.

    Abstract: A pump for dispensing a fluid, has a pump head , a piston body with a piston, a pump chamber limited by a pump chamber body, an inlet valve and an outlet valve, the piston being moveable by respective movement of the pump head between an upper starting position and a lower end position. A return stroke force for a return stroke from the lower end position into the upper starting position is provided by a bellows, formed by two bellows arranged one above the other, Each of the bellows is folded up, when moving the pump head into the lower end position, by exerting a compression force on the pump head, the first bellows receiving the compression force by direct engagement with the pump head, the second bellows receiving the compression force only by engagement with the first bellows.

    Abstract: Disclosed is a pump assembly having slidingly engaged upper and lower sleeves, and a pump having inlet and outlet ends and a pump chamber therebetween. Movement of the lower sleeve towards the upper sleeve causes the pump chamber to reduce in volume. The outlet end of the pump has a shoulder between a first diameter portion and an outlet nozzle extending downwardly from the shoulder and having a second diameter smaller than the first diameter portion. The lower end of the lower sleeve includes a shied extending from a lowermost rim upwards and inwards to terminate at an orifice that is larger than the second diameter but smaller than the first diameter portion. The shoulder supporting against a lip of the orifice and the outlet nozzle extending through the orifice to terminate at a dispersion location within the shield at a distance L from the orifice.
