The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

The present disclosure provides an atomization device, an aroma diffusion instrument, and an operation method. The atomization device includes an atomization chamber, a mixing chamber, a container, a repair cavity, a suction pump, and a gas pump; the atomization chamber is communicated with the mixing chamber through an atomization port; the suction pump is communicated with the container and the mixing chamber; the suction pump is used for pumping a substance in the container to the mixing chamber or pumping a substance in the mixing chamber back to the container; impurities in the mixing chamber can also be discharged from an opening of the repair cavity; the gas pump is connected with the mixing chamber to convey high-pressure gas to the mixing chamber; the high-pressure gas is used for atomizing liquid of the mixing chamber towards the atomization chamber; and the atomization chamber is provided with a mist outlet.

There is provided a spray apparatus. A first nozzle is configured to eject mist. A second nozzle is provided around the first nozzle. The second nozzle is configured to suck a part of the mist ejected from the first nozzle and to eject a remnant of the mist to an ejection target.

Assembly for dispensing a liquid, in particular a colorant for paint, comprising a container for holding a liquid, a pump, a valve, at least one dispense opening, and comprising or associated with a controller arranged to operate the pump and the valve to withdraw liquid from the container and to dispense liquid via the opening and to operate the pump and the valve to purge liquid from the pump to the container via the dispense opening.

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.
