1. A sprayer assembly comprising:
a sprayer assembly body; and
a cartridge housing a capillary having an outlet configured to emit liquid; wherein the cartridge comprises:
a sheath for the capillary; and
an elastic member;
wherein the cartridge is configured such that the sheath can move relative to the capillary between a first position in which the sheath covers the outlet of the capillary and a second position in which the outlet of the capillary is uncovered by the sheath; and
wherein the cartridge is configured such that, during use, as the sheath moves from the first position to or towards the second position, the elastic member provides a restoring force that acts to restore the position of the sheath to or towards the first position;
the sprayer assembly further comprising:
a nozzle that is removably attachable to the sprayer assembly body;
wherein the nozzle comprises an aperture; and
wherein the sprayer assembly is configured such that attaching the nozzle to the sprayer assembly body can retain the cartridge within the sprayer assembly body such that the liquid emitted from the outlet of the capillary will be directed through the aperture of the nozzle.
