A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate three different substantially rectangular irrigation areas. The nozzle is adjustable to function as a left strip nozzle, right strip nozzle, and side strip nozzle. The strip irrigation setting may be selected by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a flow reduction valve to set the size of the rectangular irrigation areas and may be adjusted by actuation of an outer wall of the nozzle. Other specialty nozzles are provided having a fixed pattern template to irrigate a rectangular area, such as left strip, right strip, or side strip.

A nozzle device applied to a high-pressure cleaning machine is provided, including: a nozzle, including a nozzle casing, where a water outlet channel is provided in the nozzle casing, and a front end of the nozzle casing is provided with at least one liquid discharge port connecting with the water outlet channel; and an exhaust valve, connected to the nozzle casing, and including: a valve seat, provided with a valve cavity; and a valve core, movably arranged in the valve cavity; where the valve seat is provided with an air inlet hole and an air outlet hole, the water outlet channel and a main exhaust passage are arranged in parallel in the nozzle casing, and the valve core is movable relative to the valve cavity to a closed position for blocking the main exhaust passage and an open position for opening the main exhaust passage. In the nozzle device applied to a high-pressure cleaning machine and a handheld high-pressure cleaning machine that are provided in this application, the exhaust valve is provided, and the exhaust valve implements an exhaust function at the open position, and implements a water outlet function at the closed position, thereby implementing self-suction and ensuring that a pressure anomaly is quickly eliminated within a short time during use, to meet a use requirement.

A spray wand for use with a chemical or chemical formulation in solid form. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has at least one nub, indent and/or external channel or groove on its external surface.

Disclosed is a method for calculating the depth of sprayed water of a translational sprinkler in different working conditions, involving placing rain barrels (3) in n rows in the movement direction of a translational sprinkler (1), each row having m barrels, such that the spray radius of rain droplets can completely cover the rain barrels (3) while ensuring that the translational sprinkler (1) is spraying stably; calculating the average sprinkler strength of each rain barrel (3); drawing a relationship curve of the sprinkler strength and the distance from the centre; setting the movement speed s of the translational sprinkler (1); establishing a function relationship between a sprinkler strength d′ and time t; calculating the time t2 needed for the translational sprinkler (1) to completely pass one of the rain barrels (3); and with the condition that the movement time is t2, performing mathematical integration on the sprinkler strength function to obtain the sprinkled depth of water at a certain rain barrel (3). The calculation method has a simple operation, is fast and can effectively save on costs, providing a basis for optimizing the movement speed of the translational sprinkler (1).

The disclosure relates to a pressure cleaning device comprising a pressure generating unit for pressurizing a fluid and for dispensing a pressurized fluid via a hose attachment, preferably via a hand gun or via a cleaning nozzle. The pressure cleaning device can be operated in at least two different operating modes. According to the disclosure, a preferably electric pressure sensor for determining an actual operating pressure and/or a flow rate sensor for determining an actual flow rate and a control device are associated with the pressure generating unit. The control device is designed to control the pressure generating unit in particular, based on a respectively set operating mode in accordance with an actual operating pressure and/or an actual determined flow rate.

The present disclosure relates generally to a showerhead with a pause assembly. The pause assembly can be partially received within a chamber of the housing and positioned between a fluid inlet and a plurality of nozzles to permit flow or substantially reduce flow from the fluid inlet to the plurality of nozzles. The pause assembly includes a valve and a lever coupled to the valve. The lever extends from the housing and movement of the lever in the first direction moves the valve to a first position to permit flow from the fluid inlet to the plurality of nozzles and movement of the lever in a second direction moves the valve to a second position to substantially reduce flow from the fluid inlet to the plurality of nozzles.

A shower head to jet a mist of liquid droplets includes a shower nozzle, mist throttle holes, and mist guides. The mist throttle holes are each formed into a conical hole passing through the shower nozzle. The mist guides are each formed into a conical spiral shape and each fitted in the mist throttle holes so as to define mist flow passages each having a spiral shape.

A structure of rotor nozzle is equipped with a spray unit of a watering device, the spray unit is composed of a mounting member and a housing for defining a chamber, a rotor deployed inside the chamber; wherein, at least one stopper set on the inner side of the chamber near the water outlet side is correspondingly matched to multiple guide members on one end of the water outlet of the rotor, and it can be employable to the handy watering device.

A thermo spray gun (10) includes at least one of; at least one removable nozzle tip (20) for spraying a coating material, at least one replaceable nozzle tip (20) for spraying a coating material, and at least one interchangeable nozzle tip (20) for spraying a coating material. A thermo spray gun system (1000) includes a thermal spray gun (10) and at least one mechanism (30/40) at least one of; storing at least one nozzle tip installable on the thermal spray gun and being structured and arranged to install at least one nozzle tip on the thermal spray gun. A method of coating a substrate (S) using a thermo spray gun (10) includes mounting at least one nozzle tip (20) on the thermo spray gun (10) and spraying a coating material with the at least one nozzle tip (20).

A shower head to jet an air bubble-liquid mixture by mixing air bubbles into the liquid includes a shower nozzle, a flow-adjustment piece, and air introduction passages. The shower nozzle includes an air bubble mixing space. The flow-adjustment piece is arranged in the air bubble mixing space. The air introduction passages cause air to flow into the air bubble mixing space therethrough.
