The reciprocating mechanism comprises a reciprocating shaft, a sleeve, and a first guide assembly. The driving assembly is configured to drive the reciprocating shaft to rotate, so that the sleeve reciprocates in the length direction of the reciprocating shaft; the water pump assembly comprises a water inlet member, a pump body, and a water outlet member, the pump body is connected to the sleeve, the pump body is communicated between the water inlet member and the water outlet member, and when the pump body moves along the axis of the reciprocating shaft, the pump body is configured to feed water from the water inlet member and discharge water from the water outlet member.

A portable liquid-delivery system includes a portable container configured to store an internal liquid, the portable container having a peripheral wall extending along a central axis between a top wall and a bottom wall, the portable container including a cutout disposed partially inward between the peripheral wall and the central axis. A mounting module is configured to mount the portable container to a transportation device. The portable liquid-delivery system further includes a sprayer module that dispenses the internal liquid externally from the portable container.

A pressure washer includes a port for a liquid source, a high-pressure pump, a main line, through which liquid can be conveyed from the port to a spray opening of the main line by the high-pressure pump, a control element for setting a pressure value for the pressure in the main line, and a pressure regulator, which adjusts the pressure in the main line according to the pressure value set by the control element. The control element is continuously adjustable along a travel path. Each position of the control element sets a specific pressure value. The pressure washer has a selector element for selecting at least two different characteristic curves, each with a different relationship between positions of the control element and pressure values. By selecting a characteristic curve using the selector element, the assignment of the position of the control element to the pressure value can be changed.

A routing system for an agricultural sprayer includes a support configured to operably couple with the sprayer. An adaptor is configured to transfer a flow therethrough. The adaptor is at least partially positioned within an envelope defined between a wheel assembly and laterally offset components of the sprayer. A conduit has a first section operably coupled with a first portion of the adaptor and a second section operably coupled with an opposing second portion of the adaptor. The first section and the second section of the conduit are configured to transfer the flow therethrough such that the flow is serially transferred through each of the first section of the conduit, the adaptor, and the second section of the conduit.

A system includes a frame, a spot-free water generator, a booster pump, a tank, a first pressure washer, and a first on-demand pump. The frame is configured to be received within and coupled to a portion of an interior of a vehicle. The spot-free water generator includes a carbon filter, a pre-filter, and a plurality of membranes and is configured to generate spot-free rinse water from tap water. The booster pump receives tap water from an exterior water inlet port and delivers the tap water to the spot-free water generator at a predetermined pressure. The tank is coupled to the frame and receives and stores at least a portion of the spot-free rinse water generated by the spot-free water generator. The first on-demand pump is coupled to the frame and is configured to deliver spot-free rinse water from the tank to the first pressure washer.

A handheld cleaning machine, comprising: a housing, a reciprocating mechanism, a driving assembly, and a water pump assembly. The reciprocating mechanism comprises a reciprocating shaft, a sleeve, and a first guide assembly. The driving assembly is configured to drive the reciprocating shaft to rotate, so that the sleeve reciprocates in the length direction of the reciprocating shaft; the water pump assembly comprises a water inlet member, a pump body, and a water outlet member, the pump body is connected to the sleeve, the pump body is communicated between the water inlet member and the water outlet member, and when the pump body moves along the axis of the reciprocating shaft, the pump body is configured to feed water from the water inlet member and discharge water from the water outlet member.

A pressure washer includes a main line through which, via a high-pressure pump, liquid can be conveyed to a spray opening, and a main valve. The main valve, when in a closed state, prevents liquid from flowing through the main line and, when in an open state, allows liquid to flow through the main line. The main valve is switchable between open and closed via an operator-controlled element. The main line has a suction chamber between the connection and the pump and a pressure chamber between the pump and the spray opening. The pressure chamber is fluidically connected to the suction chamber via a bypass line. A free cross-sectional area of the bypass line is settable via a bypass valve in the bypass line for regulating pressure in the pressure chamber. The bypass valve is adjustable via the operator-controlled element for setting the free cross-sectional area of the bypass line.
