Then, the stroller toy is placed on the upper end of the fixed seat 3. Then, the fixed plates 5 are released. The fixed plates 5 will return to their original position under the force of the spring 6 and fix the stroller toy. Then, the spraying chamber door 2 is closed. Then, the linear guide rail 81 is opened by the microcontroller 7. The mounting shell 82 is adjusted to a suitable height according to the height of the stroller toy. Then, the motor 9 is turned on by the microcontroller 7. The motor 9 drives the fixed seat 3 to rotate the stroller toy. Then, the motor 87 and the external negative pressure pump are turned on by the microcontroller 7. The output shaft of the motor 87 drives the turntable 83 to rotate, driving the sliding rod 86 to swing up and down and drive the spray head 85 to swing in the opposite direction, thereby realizing the spraying of the stroller toy.
