Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] Current oral irrigator nozzle devices are usually formed in one piece. Since the steel needle (water passage section) used in the mold is too thin and too long, the steel needle is very likely to deform and break during the mold production process. This makes it difficult for the water outlet aperture of the one-piece nozzle device to be small (for example, less than 0.6 mm), and thus the water pressure cannot be effectively increased, affecting the flushing and cleaning effect on the teeth.
