The utility model belongs to the technical field of flushers, and discloses an
oral cavity flusher which comprises a
machine shell and a water tank fixed to the bottom of the
machine shell, a
nozzle is detachably connected to the top of the
machine shell, and a liquid pump, an
air pump and a two-position three-way
electromagnetic valve are fixedly arranged in the machine shell. The
nozzle is communicated with a liquid pump and an
air pump through a two-position three-way
electromagnetic valve, a liquid conveying
pipe and an air conveying
pipe are connected between the liquid pump and the water tank and between the
air pump and the water tank respectively, and the liquid conveying
pipe and the air conveying pipe both extend to the bottom of the water tank. The two-position three-way
electromagnetic valve and the air pump are arranged, when mixed liquid of clear water and washing agents is used for washing the
oral cavity, the clear water and the washing agents are added into the water tank respectively, and the nozzles are communicated with the air pump through the two-position three-way electromagnetic valve. The air pump is started to introduce external air into liquid in the water tank through the
nozzle, the air pump and the air delivery pipe in sequence, and clear water and the flushing agent are automatically mixed through air stirring.
