I wondered about
zoreh, and then thought, "the person isn't spraying something into the wind, but rather directly into their nose or mouth, so would the air inside a person's body be included"? But spraying something directly into the wind is per the Yerushalmi rather than the Bavli, and many rabbis throughout the ages have disagreed.
Rabbi David Botton says that it's okay to use a spray deodorant onto the body, but not to "Spray yourself with a perfume in a venturi-tube style container (old perfume bottles with the bulb and tube hooked to a nozle that has a straw going down to the perfume)." I'm not sure what the difference is.
Many big poskim seem to be mekeil when it comes to spraying in general:
