This application will heat the module and concentrate to this internally of shower nozzle, can be better carry out modularization, unitization. Specifically, the nozzle body is also provided with components such as a fan and the like. The shower nozzle body is conveniently changed, easy operation, it is efficient.

Furthermore, the surface of the extruding motor provided with the groove and the surface of the nozzle body provided with the first powerful magnet are both made of aluminum materials. The aluminum product quality is light, can be better subtract heavy, convenient heat dissipation simultaneously.

Furthermore, the surface of the extruding motor provided with the groove is fixedly provided with a radiating fin, and when the first powerful magnet and the second powerful magnet are attracted, the radiating fin is back to the surface of the extruding motor and the surface of the sprayer body provided with the first powerful magnet are attached. The radiating fins can better radiate heat, and the heat accumulated between the extruding motor and the nozzle body is reduced.

Furthermore, the radiating fin is arranged at the left lower part of the extruding gear, and one side of the radiating fin, which is opposite to the extruding gear, is provided with a circular arc-shaped notch. The heat of the extruding gear can be better dissipated, and the heat dissipation effect is improved.

Furthermore, air duct through holes are formed in the extruding motor and the spray head body. The heat dissipation can be better performed.

Further, the radiating fins are fixedly connected with the extruding motor through bolts. The installation is convenient, simple and convenient.

Further, the first powerful magnet and the second powerful magnet are both cylindrical. The production and the manufacture are convenient, and the positioning is accurate.

Further, the diameter of the first powerful magnet and the diameter of the second powerful magnet are 10mm, and the thickness of the first powerful magnet and the thickness of the second powerful magnet are 5 mm. Is convenient to use.

Furthermore, the material extruding motor is connected with the x-axis sliding block. The installation and the use are convenient.

In conclusion, the shower nozzle has the advantages of better shower nozzle replacement, simple and fast operation and high efficiency.
