A fluidic component having a flow chamber allowing a fluid flow to flow through, said fluid flow entering the flow chamber through an inlet opening of the flow chamber and emerging from the flow chamber through an outlet opening of the flow chamber, and which flow chamber has at least one means for changing the direction of the fluid flow at the outlet opening in a controlled manner. The flow chamber has a main flow channel, which interconnects the inlet opening and the outlet opening, and at least one auxiliary flow channel as a means for changing the direction of the fluid flow at the outlet opening in a controlled manner. The inlet opening has a larger cross-sectional area than the outlet opening or the inlet opening and the outlet opening have cross-sectional areas that are equal in size.

An execution system (100) for a fluid micro-injection device and a fluid micro-injection device are provided. The execution system (100) has a base body (110), a movable member (120), an executor and an adjusting member (130). The adjusting member (130) is disposed in the executor mounting cavity (110) and connected with the executor. The adjusting member (130) is adjustable for adjusting a pre-tightening force of the executor.

A spray gun shower head includes a shower body and a waterway closing element. The shower body is disposed with a first water passageway communicated with a water intake opening and a first water outflow opening (12), and a second water passageway communicated with the water intake opening and a second water outflow opening. The second water passageway is configured to spray the spray gun water. The waterway closing element is rotatable to a second switch position to open the second water passageway and close the first water passageway while driving an opening structure to push against a cover to be flipped up, so that the second water outflow opening hidden in the shower body by the cover sprays the spray gun water.

The present disclosure proposes a coating nozzle, a coating device and a corresponding coating method. The nozzle includes: a first reactant spout configured to spray a first reactant; a second reactant spout configured to spray a second reactant; and a first air curtain spout configured to spray shielding gas, so that the sprayed shielding gas forms an air curtain which isolates the first reactant from the second reactant. The device includes: one or more coating nozzles described above; and a transport mechanism configured to transport an object to be coated, so that the object to be coated sequentially passes through a first reaction region of the first reactant and a second reaction region of the second reactant for each of the one or more nozzles.
