Pulse wall nozzle for bathtub

A pulse wall nozzle for a bathtub, comprising a nozzle body, a nozzle cover and a rotating roller,

• wherein the nozzle body is hollow inside and cooperates with the nozzle cover to form a cyclone cavity, and the nozzle body is provided with a water inlet;
• the nozzle cover is detachably installed on the nozzle body, a plurality of water spray holes is defined in a surface of the nozzle cover opposite from the nozzle body and arranged in a length direction of the nozzle cover, and a side of the nozzle cover close to the water spray holes is provided with an air outlet facing the water spray holes;
• and
• the rotating roller is rotatably arranged in the cyclone cavity, and water from the water inlet is capable of driving the rotating roller to rotate, so that the rotating roller rotationally cooperates with the water spray holes to control the water spray holes to generate pulsed fluid;
• wherein the rotating roller comprises a plurality of quasi-cylindrical rotating units each of which comprises a cylindrical surface and an arc surface;
• a radius of the arc surface is gradually reduced, and a maximum radius end of the arc surface is connected with an end of the cylindrical surface;
• a minimum radius end of the cylindrical surface is connected with an opposite end of the cylindrical surface through a connecting surface, and the connecting surfaces are arranged in a staggered manner.
