When the transmission gear 209 rotates within the range of 0-120 degrees, the first one third gear is meshed and driven to rotate so as to pump out the first dye liquor; when the transmission gear 209 rotates within the range of 120-240 degrees, the transmission gear is meshed with and drives a second one-third gear to rotate so as to pump out a second dye solution; the transmission gear 209 is meshed to drive the third gear to rotate when rotating within the range of 240-360 degrees so as to pump out the third dye liquor. By means of the design, different dye liquids can be pumped at different times. The liquid pumping mechanism 2 is provided with five duckbill-shaped spraying heads 201, and liquid is in a water curtain shape when the liquid is sprayed.

The case 3 is mainly composed of a case 302, a vent hole 306, a sub-case 308, a case cover 309, a reservoir cover 307, a reservoir 301, a fan 303, a through hole 306, and a reservoir pipe 305. A vent hole 306 is provided in the case housing 302. The tank 301 is used for storing dye liquor, and the tank pipe 305 is connected with the input pipe 204 through the one-way valve 207. The liquid in the tank 301 reaches the dye liquor spraying device (spraying head 201) through the output pipe 205, and then the dye liquor is sprayed. A fan 303 is located on the side wall of the case for air drying the slides.
