The invention discloses a spray nozzle. The spray nozzle comprises a body, a water separation valve, a switching valve and a switch, wherein a water inlet channel, a first water outlet channel, a channel, a second water outlet channel and a third water outlet channel are formed inside the body, wherein the first water outlet channel and the channel communicate with the water inlet channel, and thesecond water outlet channel and the third water outlet channel communicate with the channel. According to the spray nozzle, the water separation valve is used for correspondingly blocking the first water outlet channel or the channel when the water separation valve is in different positions; the switching valve is used for correspondingly blocking the third water outlet channel or the second water outlet channel when the switching valve part is in different states; the switch is used for controlling and blocking the third water outlet channel, so that the water separation valve blocks the channel; and a user can operate the switching valve and the switch to adjust the spray nozzle to achieve switching among the three different water outlet modes.
