Infectious diseases may be acquired in public areas such as transportation terminals, shopping centers, schools, hospitals, restaurants and hotels. Large surface areas may be disinfected using a spray system to distribute a suitable fluid such as a disinfectant. Many existing spray systems are large and unwieldy causing operator fatigue. Some spray systems have large, heavy external tanks that provide fluid to the spray system using an external fluid hose. Disclosed is an improved portable spraying system that may be carried by a system operator. The improved system has a tank, a quick connect, a pump, a valve, a nozzle, and a fan all powered by a battery. The tank, the pump, and the battery are arranged to minimize operator fatigue. With the valve set to the priming position, fluid recirculates to prime the pump. Once the pump is primed, the valve is turned to the spray position to begin spraying. The quick connect allows an external tank such as a backpack tank to be connected to the sprayer.

A container unit including a plurality of container sub-portions (4) defining a plurality of chambers for containing a liquid substance, each container sub-portion including an outlet, the container unit further including a conduit device (12) serving to connect each of the outlets of the respective sub-portions to an outlet nozzle (8a). In one embodiment, a spray cycle is disclosed having first and second periods of flow allowance and purging respectively. In another embodiment, respective sub-portion (4) controllable liquid displacement devices for dispensing one or more of the liquid substances selected from one or more of the respective sub-portions (4) are disclosed.

A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

The present invention relates to a perfume dispensing device, the device being electronically controlled and the actuation of perfume spraying being performed via an actuator (12) located on or under a device housing (1). All components of the device are located on or in the housing (1), wherein the housing also accommodates a control circuit (10) for controlling the device, which may optionally include a system (13) for wireless communication with a smart device (14) having a dedicated application uploaded, through which the user sets the desired parameters. The device may include several storage containers (2), which allows the user to select the desired perfume or to personalise the perfume via a dedicated application. The actuator is actuated by pressing or touching the actuator (12) or via an external device.

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.

A multicolor powder center supplies at least one powder spraying device with different types of coating powder as required. The multicolor powder center has at least one powder container for receiving coating powder and at least one pump unit comprising at least one powder pump, in particular a dense flow pump or a diluted flow pump. The pressure side of the at least one powder pump is fluidically connected or can be fluidically connected to the powder inlet of a powder spraying device. The at least one powder container has at least one suction channel which is preferably formed in a suction pipe and which has a suction opening that opens into the interior of the powder container and an opposite discharge opening that opens into a connection, wherein the suction side of the at least one powder pump can be fluidically connected to the connection of the powder container.

A multi-compartment sprayer with a main body and an outer casing and which houses a plurality of conduits intended for containing fluids to be sprayed independently. It includes movable equipment having a rotary movement assembly which rotates about a guide shaft of the sprayer and allows selecting the product to be sprayed and has an unlocking movement assembly configured to move axially in the direction of the guide shaft. Likewise, the sprayer includes fixed equipment with a fixed casing inside which the movement assemblies are arranged and with an actuating trigger and a locking button to allow/prevent the change of nozzles for product selection.

A correctional paint wand used to mark lines on pavement, turf, concrete, and other surfaces. It has a rotatable sleeve on the lower end of an elongated handle, with the sleeve having at least two aerosol paint can holders each sized for containing one inverted paint can. At least one can applies distinguishable marking paint, and at least one can applies correctional paint visually covering erroneously applied markings, with the sleeve rotated to place the needed paint can in a dispensing position. A wheel on the lower end of the wand may aid its movement over the surface targeted for marking. The error correcting paint may be green for grass or artificial turf, brown for exposed ground, light gray or off-white for cement, and black for asphalt, or other colors appropriate to the intended application. Contemplated applications include, but are not limited to, use by landscaping designers and utility companies.

A hand-held dispenser to dispense fluid includes a casing to fit into a hand of a user, a nozzle in the casing to dispense a mist, a fluid reservoir contained in the casing to hold a fluid to be turned into the mist, a filament extension atomizer contained in the casing to generate the mist, an air source contained in the casing to provide air flow to direct the mist to the nozzle, a motor contained in the casing to operate the filament extension atomizer, an actuator positioned on the casing to activate the dispenser, a control circuit contained in the casing to receive a signal from the actuator and to send a signal to the motor to cause the motor to actuate, and a power source contained in the casing to provide power to the motor upon receive a signal from the control circuit.
