The frequency conversion rotating mechanism 15-3 adopts a motor. Other products capable of realizing the frequency conversion rotation function can be adopted instead.

The utility model discloses an overall design rationale of shower nozzle combination: the structure of the cam 15-2-7 is in an elliptical frustum shape, one end of the cam 15-2-7 close to the variable frequency rotating mechanism 3 is a large end, and one end of the cam 15-2-7 far away from the variable frequency rotating mechanism 15-3 is a small end. When the feed motor 15-2-2 stops rotating, a certain point of the cam 15-2-7 is contacted with the universal ball 15-4-8, and when the motor of the variable frequency rotating mechanism 15-3 rotates at a certain rotating speed n, the cam 15-2-7 rotates at the rotating speed n, so that the piston rod 15-4-5 is driven to move up and down.

The shaft section of the cam 15-2-7 is oval, and the motion frequency of the piston rod 15-4-5 is 2 n; when the piston rod 15-4-5 moves upwards, the piston 15-4-4 enables the material suction cavity 15-4-3-2 to form negative pressure, at the moment, as the flexible plug 15-4-12 in the material discharge one-way valve cavity 15-4-3-4 clings to the inner top surface to plug the material discharge channel 15-4-3-3, and the material spray channel 15-4-16 in the material spray head 15-4-15 is equivalent to a closed state, the coating can be sucked into the material suction cavity 15-4-3-2 from the material cylinder 19 through the one-way valve 18. And when the piston rod 15-4-4 moves downwards, the check valve 18 on the material barrel 19 is closed, the piston 15-4-4 enables the material suction cavity 15-4-3-2 to form positive pressure, at the moment, as the flexible plug 15-4-12 in the material discharge check valve cavity 15-4-3-4 is separated from the inner top surface to move downwards, the material discharge channel 15-4-3-3 is opened, and the material spray channel 15-4-16 in the material spray head 15-4-15 is equivalent to an open state, the coating can be sprayed out from the material spray channel 15-4-16 in the material spray head 15-4-15, enters the atomization cover 15-5 and is atomized through the atomization cover 15-5. When the rotating speed n of the variable-frequency rotating mechanism 15-3 is changed, the coating point sprayed out by the spray head is changed, and variable-frequency control is formed.

When the feed motor 15-2-2 stops rotating, a determined oval circle on the cam 15-2-7 is in contact with the universal ball 15-4-8, the amplitude of one rotation of the cam 15-2-7 is b-a, namely the coating amount V is s (b-a), wherein s is the cavity cross-sectional area of the piston cavity 15-4-3-1, b is the major axis radius of the oval, and a is the minor axis radius of the oval. When the feed motor 15-2-2 rotates, the screw 15-2-3 rotates along with the feed motor, so that the feed slider 15-2-4 is driven to move transversely, the cam 15-2-7 is driven to move transversely, after the cam 15-2-7 moves transversely, the elliptical circle on the cam 15-2-7 which is in contact with the universal ball 15-4-8 changes along with the elliptical circle, and the amplitude b-a of the elliptical circle changes along with the elliptical circle, so that the amplitude variation is controlled, namely the discharge quantity at each time is controlled.
