A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.

A release agent spray system for a vehicle that is used for removing temporary tape from pavement surfaces. The release agent spray system includes a reservoir containing a release agent, a pump for pumping release agent from the reservoir, and a handheld sprayer connected to the reservoir by a fluid conduit or tube and connected electrically to the pump. The handheld sprayer includes an activation switch for activating the pump to deliver release agent from the reservoir to the handheld sprayer.

A disinfectant and sanitizer canister system is disclosed. The system may include a pre-pressurized canister being pre-filled with one or more liquid cleaners and one or more propellants. The system may further include a valve sub-system including a dispensing valve and a valve control mechanism. The control mechanism may be configured to regulate the pressure of the pre-pressurized canister to cause the pre-pressurized canister to release the one or more liquid cleaners. The system may further include a dispensing sub-system configured to fluidically couple the pre-pressurized canister to the valve sub-system. The dispensing sub-system may include a dispensing member configured to dispense the one or more liquid cleaners contained within the pressurized canister. The system may further include a metering device, the metering device configured to provide a predetermined amount of pressure to dispense a predetermined metered dose of the one or more liquid cleaners.

Shrouds for preventing unintentional engagement or initiation of triggers of trigger operated devices during handling of the trigger operated device are described.

Device (1) for spraying active material comprising a case (2) fixed on a support (3), said case (2) containing a liquid solution containing at least one active material in a tank (7), said solution being ejected through an ejection orifice (4), said tank (7) being equipped with an activatable diffusion mechanism (10), which communicates with an electronic circuit (10), powered by a battery (11), the activation of which triggers spraying, characterized in that the ejection orifice (4) is connected to a tubular duct with a length of between 5 and 70 cm provided with at least one outlet orifice (5′) for offsetting the ejection of said active material in the form of fine liquid particles.

A backpack sprayer includes a housing, a spray nozzle assembly, a fan assembly and a switch assembly. The housing is configured to contain a liquid. The spray nozzle assembly is communicated with the housing, and is configured to spray the liquid out from the housing. The fan assembly is connected to the spray nozzle assembly, and is configured to provide the spray nozzle assembly with power to spray the liquid out from the housing. The switch assembly is connected to the spray nozzle assembly and electrically connected to the fan assembly, and is configured to control opening and closing of the spray nozzle assembly and start and shutdown of the fan assembly simultaneously.

The disclosure discloses a connection structure and a spray shower. A connection structure includes a first object, a buckle and a second object. The first object includes a connection channel and a sliding slot perpendicular to the connection channel. A retaining wall and a plug-in channel are provided between the sliding slot and the connection channel. An insertion buckle is provided with a buckle body slidable in the sliding slot and an insertion piece adapted to be inserted in or retracted from the connection channel through the plug-in channel. The second object is inserted into the connection channel and is provided with a recess matching the insertion piece. The spray shower includes the connection mechanism. The connection structure and the spray shower are mechanically connected.

A water outflow control assembly includes a water inlet body, a push rod, a rotor and an elastic member. The water inlet body is provided with a valve cavity. One end of the valve cavity is provided with a push rod hole for sliding of the push rod. The push rod is provided with push blocks. The rotor is provided with tooth blocks extending toward the push rod hole and matching with the push blocks, and a retaining wall with a gap. The retaining wall is in clearance fit with an inner wall of the valve cavity, and rotation of the rotor changes a degree that the retaining wall blocks a water inlet channel. By adopting the shower head with above mentioned assembly, the water outflow control assembly can be installed through a handle hole of a shower head body of a shower head.

Pneumatic spray gun (10) and cartridge tip assemblies for applying sprayable materials to various surfaces are disclosed. A tube of flowable texture material to be sprayed having a cartridge tip (100) may be loaded into a pressure canister of a texture material spray gun (10). The cartridge tip (100) may include radially outwardly extending ribs (130), radially inwardly extending recesses and/or other features that engage with corresponding features of the spray nozzle assembly to reduce or prevent relative rotation between the cartridge tip (100) and the spray nozzle assembly.

A ground-mounted soap injection system that can be used with a SLIP 'N SLIDE or other similar device needing the addition of a lubricating agent. The invention includes a liquid reservoir connected to a metering valve and an injection venturi. A hose is connected to the device and water passing through an internal passage draws the lubricating agent into the moving stream in a controlled fashion. Spikes are provided to secure the device to the ground.
