Detailed Description

The following detailed description of the utility model, taken in conjunction with the accompanying drawings, will provide those skilled in the art with a more readily understood understanding of how the utility model may be practiced. While the present utility model has been described in connection with the preferred embodiments thereof, these embodiments are set forth only and are not intended to limit the scope of the utility model.

First embodiment: referring to fig. 1-3, a water mist head, comprising: the spray head comprises a spray head body 1, a connecting pipe 2, an adjusting pipe 3 and a plurality of spray nozzles 4.

A confluence cavity 101 with one end open is formed at the axis of the nozzle body 1, and a plurality of diversion holes 102 are formed at the periphery of the nozzle body 1; the plurality of tap holes 102 are uniformly distributed; the split flow hole 102 is in spatial communication with the converging cavity 101; in this embodiment, the diversion holes 102 are used for accommodating the nozzles 4, where the diversion holes 102 are disposed in a one-to-one correspondence with the nozzles 4, and further, the nozzles 4 are in threaded connection with the nozzle body 1.

The connecting pipe 2 is fixedly connected with the lower end of the nozzle body 1, and the connecting pipe 2 is coaxial with the converging cavity 101; in other embodiments, to ensure the stability of the structure, the nozzle body 1 and the connecting pipe 2 may be integrally formed; the inner periphery of the connecting pipe 2 is provided with internal threads.
