This invention discloses a mechanical boost type cup spray-washing unit integrated with temperature-adjustment and press-control. This unit may regulate the mixing proportion of the cold water and hot water. It in combination with the boosting spray-wash effectively dissolves and washes the residues and juice on the inner wall of cup. This unit is clever in structure, integrates the temperature-adjustment and flush-washing, is directly hidden in the intermediate of the desk installation holes, never occupies surplus space of the kitchen desk, and may be installed in the standard small-hole of the kitchen water-trough desk without extra-opening, or may be directly fixed above the bottom of the water-trough after removal of the drain-panel.

High pressure water jet gun comprising: a dispensing body (6); a gripping body (13) connected to the dispensing body (6); an actuation member (10) reversibly movable between an activation position, wherein it is active on a shutter member (9) in order to at least partly cause an open condition, and a rest position, corresponding to a closed configuration of the shutter member (9); a blocking means (15) reversibly movable between a safety configuration, in which it is active on the actuation member (10) to prevent a passage from the rest position to the activation position, and a working configuration, wherein it enables a reversible passage of the actuation member (10) between the rest position and the activation position. In particular, the blocking means (15) comprises a manual activation element (21) at least partially opposed to the gripping body (13) with respect to the dispensing body (6). The actuation member (10) and the activation element (21) are arranged on opposed portions of the dispensing body (6) so that a single hand of the user can act on the activation element (21) with the thumb and on the actuation member (10) with at least another finger of the same hand.

High pressure water jet gun (1) comprising: a dispensing body (6); a gripping body (13) connected to the dispensing body (6); an actuation member (10) reversibly movable between an activation position, wherein it is active on a shutter member (9) in order to at least partly cause an open condition, and a rest position, corresponding to a closed configuration of the shutter member (9); a blocking means (16) reversibly movable between a safety configuration, in which it is active on the actuation member (10) to prevent a passage from the rest position to the activation position, and a working configuration, wherein it enables a reversible passage of the actuation member (10) between the rest position and the activation position. In particular, the blocking means (16) comprises an activation element (17) mounted on the dispensing body (6) and slidably reversibly movable with respect to the dispensing body (6) between a retracted position, corresponding to the safety configuration of the blocking means (16), and an advanced position, corresponding to the working configuration of the blocking means (16).

A liquid spraying system having a liquid spray section and a controller for controlling liquid to the spray section. The controller includes a valve operable between multiple positions for controlling the supply of liquid to the spray section and enabling the flow of liquid from the spray section to a flow back line only after the liquid supply to the spray section has been terminated.

A water outlet device with water stop and flow rate control comprises a body, a water stop assembly, and a flow rate control assembly. The body comprises a water outflow passage. The flow rate control assembly and the water stop assembly are disposed on the body, first ends of the water stop assembly and the flow rate control assembly are respectively disposed in the water outflow passage, and second ends of the water stop assembly and the flow rate control assembly are exposed out of the body to respectively define a water stop operation end and a flow rate control end. The water stop assembly comprises a first shaft that is operatively connected to the water stop operation end. The flow rate control assembly comprises a second shaft that is operatively connected to the flow rate control end.

A water spray gun for control of an outflow of water and adjustment of the amount of the outflow is revealed. The water spray gun includes a handle portion, a pipe portion connected to the handle portion and used for spraying water, and a control device arranged at the position where the pipe portion meets the handle portion. The control device comprises a press part and a rotary control member. The amount of the water outflow is controlled by the rotary control member. The amount of the outflow sprayed out from the pipe portion at respective stages is continuously controlled and regulated by the control device.

A water spray gun includes a main body, an operating member and a switch part. The main body includes a handle portion and a tube portion extended from the handle portion and provided with a spray head. A control assembly is enclosed in the main body for control of water outflow and adjustment of the amount of the water outflow. The operating member is pivotally connected to the position where the handle portion meets the tube portion. The switch part is arranged at the operating member and is engaged with the control assembly. The amount of water outflow is controlled by relative movement between the switch part and the operating member.
