Abstract:
Provided are a spray head (100) of a nozzle (200), a nozzle (200), and an oral irrigator. The spray head (100) comprises a spray head main body (1) and a stop structure (2). A first flow channel (10) is defined in the spray head main body (1). One end of the first flow channel (10) is formed as a water inlet (10a), and the other end of the first flow channel (10) is formed as a water outlet (10b). The stop structure (2) is arranged on the outer circumferential wall of the spray head main body (1) and comprises two abutting portions (21) arranged opposite to each other in the radial direction of the first flow channel (10). The two abutting portions (21) extend away from each other. In the radial direction of the first flow channel (10), the water outlet (10b) is located between the free ends of the two abutting portions (21). The two abutting portions (21) are suitable for separately abutting against adjacent teeth in the same row, and the teeth against which the two abutting portions (21) abut are different, so that the water outlet (10b) is suitable for being opposite to a diastema between the adjacent teeth.
