A delivery device (5) for injecting a liquid active ingredient formulation (4) into a plant comprises a vessel assembly (51, 52) having a distal side (512) and a proximal side (523), a delivery outlet (53) connected to the distal side (512) of the vessel assembly (51, 52), a product port (57) connected to the distal side (512) of the vessel assembly (51, 52), a dosing piston (511) movably arranged in the vessel assembly (51, 52) such that a variable product chamber (515; 595) is formed between the dosing piston (511) and the distal side (512) of the vessel assembly (51), a directional valve (54) connected to the proximal side (523) of the vessel assembly (51, 52), a proximal chamber (525) limited by the proximal side (523) of the vessel assembly (51, 52) and reciprocally variable relative to the product chamber (515), and a pressure medium port (541) connected to the directional valve (54). The directional valve (54) is configured to switch between a delivery position in which the proximal chamber (525) of the vessel assembly (51, 52) and the pressure medium port (541) are in fluid connection, and a charging position in which the proximal chamber (525) of the vessel assembly (52) and the pressure medium port (541) are fluid tight towards each other.

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.

An inkjet coating machine is provided to prevent the components in the paint from precipitating. The inkjet coating machine includes: a robot arm having a chuck at a front end and a nozzle head unit detachably mounted on the chuck. The nozzle head unit includes a nozzle head having a nozzle for spraying the paint, a nozzle control unit for controlling driving of the nozzle, and a head-side circulation path enabling the paint to circulate within the nozzle head. The nozzle head, the nozzle control unit and the head-side circulation path are integrally configured. The coating machine further includes a standby holding unit that holds at least one nozzle head unit in standby and a head replacement unit that replaces the nozzle head unit.

The invention relates to a method for controlling an electrostatic atomizer for liquids, the atomizer comprising a liquid tank and a delivery device for liquid from the liquid tank, a high-voltage source and also at least one atomizer nozzle for the atomization of liquid, the at least one atomizer nozzle being connected to the high-voltage source. Here, the voltage and/or the current intensity at at least one of the atomizer nozzles are detected by sensors of control electronics and/or the voltage and/or the current intensity at the high-voltage source are detected by sensors of the control electronics.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.

This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit having a storing part to store the liquid, the atomization unit being configured to generate an aerosol by atomizing the liquid; and a temperature control part configured to control the temperature of the liquid at a given location between the accommodating part (cartridge) and the storing part.

A fluid dispenser assembly comprising a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62), the fluid reservoir (4) including a piston (42) that is movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir, the dispenser assembly being characterized in that it further comprises an RFID tag (40) that is secured to the piston (42).

An electrostatic spinning device including a nozzle that sprays spinning liquid that has been charged; a switch that controls spray operation of the spinning liquid; and a housing that includes a bulging portion and a grip portion for grip of the user, the bulging portion bulging outward from a virtual line connecting a tip of the nozzle and an end of the switch on a side of the nozzle, an angle formed by an axis of the nozzle and an axis of the grip portion being 45 degrees or more.

A product applicator assembly including a housing having a first end and a second end;

a dispensing force; a dispensing device operatively attached to the dispensing force; at least one power source; a dispensing switch operatively attached to the dispensing force; a data operator electrically connected to an electrical power source. Also provided is a bait applicator and a method of using the applicator to apply bait.
