An integrated device for water streaming and spraying comprises a support base, a water inlet pipe mounted on the support base, a nozzle including an outer tube mounted on the water inlet pipe and an inner tube, an adjustment sleeve making sealing contact with the outer tube, and a position adjustment mechanism capable of adjusting a position of the adjustment sleeve along front and rear directions. The inner tube provided with a plurality of guide vanes is disposed in and protruding from the outer tube. A cavity of the inner tube is provided with a partition plate, the partition plate and an inner wall of the inner tube together encircle to form an opened diversion groove having a groove wall provided with at least one notch. The adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the opened diversion groove.

A device suitable for dispensing a liquid substance, such as an ophthalmological substance, including a container; a dispenser for dispensing the substance and which includes a piston element, loaded by the pressure of the pressurized substance so as to adopt a standby position by default that prevents the preloading chamber from being flooded by a dose of the substance; and a valve element capable of enabling a connection between the preloading chamber and the outside. The device has an actuation mechanism that sequentially compresses a volume of air used for moving the piston element from the standby position thereof, allowing a dose of the substance to flood the preloading chamber to subsequently mechanically actuate the valve element and simultaneously enable the connection to the outside of the preloading chamber as well as of the volume of air previously used for moving the piston element from the standby position thereof.

The present disclosure is intended to provide a discharge apparatus and an industrial robot, discharge apparatus having a relatively simple configuration capable of removing a remainder of a discharge material remaining in a discharge nozzle and a feeding channel, enabling cost reduction, and having a structure which is easy to clean and with which a function of preventing drips can be imparted. The discharge apparatus includes: a nozzle head having a plurality of feeding channels for feeding a discharge material, and a removal channel communicating with the feeding channels and usable for removing a remainder of the discharge material remaining in the feeding channel; a plurality of discharge nozzles configured to be attached to the nozzle head such that each of the plurality of discharge nozzles is connected to an associated one of the plurality of feeding channels; a delivery tube configured to deliver the discharge material selectively to one of the plurality of feeding channels so that the discharge material is discharged from the discharge nozzle; and a suction tube connectable to the removal channel and usable for sucking the remainder of the discharge material remaining in the feeding channel and the discharge nozzle through the removal channel.

The present invention relates to pathogen cleaning and simulation of pathogen spreading. More particularly, some implementations of the described invention relate to systems and methods for spraying materials in a manner that mimics the spreading of pathogens from coughing or sneezing. Some implementations further relate to using a non-aerosol sprayer that produces both a mist and droplets of a mixture containing water, a fluorescent marker, a surfactant, and an antifoaming agent. In some cases, the pump sprayer defines an internal compartment that includes the mixture. In some cases, the sprayer further includes a pump mechanism that is configured to be pumped to compress a gas within the compartment and a release valve that is configured to release pressure within the compartment through a spray nozzle of the sprayer such that droplets and mist of the mixture are sprayed from the nozzle. Other implementations are also described.
