It should be noted that, the dip-dyeing is implemented by putting the dip-dyed component (i.e. the target product) into the dye vat, and the length of the dip-dyeing time affects the color depth of the surface of the component.

In addition, the kinds of the dyeing liquids are one or more, and each of the dyeing liquids is stored in one dye vat.

And putting the target product into a dyeing liquid tank for dip dyeing, selecting different dyeing liquid formulas for different colors, and realizing the setting of the depth of the color on the surface of the target product and the gradual change of the same color or the transitional gradual change among different colors by the length of dip dyeing time and the up-down lifting of the target product.

The same color depth gradual change can be realized by changing the dip dyeing time of the target shell and changing the region of the target shell immersed in the dyeing solution by lifting the target shell up and down, different color gradual changes are realized by firstly dip dyeing one end part region of the target shell and then dip dyeing the other end part region of the target shell by the same method, the specific region size and position can be controlled by the target shell according to the preset condition requirement, and the region of the target shell immersed in the dyeing solution can be changed by lifting the target shell up and down, so as to achieve the required single-color or multi-color gradual change effect. And if the segmented gradual change effect is required to be achieved, the ink protective layer can be coated on the area which does not need to be dyed, and the arrangement can only dip-dye the area which needs to be dip-dyed, so that the appearance effect of any gradual change color of multiple segments of multiple colors of the product appearance is realized.

Finally, it should be noted that after the product with the gradually changed surface color is obtained, a finish paint may be sprayed on the surface of the product with the gradually changed surface color to protect the product with the gradually changed surface color.

In the embodiment of the invention, the transparent product to be dyed is prepared by using the transparent plastic raw material, then the target dye is sprayed on the product to be dyed to obtain the target product, and finally the first target area is put into the dyeing solution for dip dyeing according to the dip dyeing time to obtain the product with gradually changed surface color, so that the aim of coloring the product by using a dip dyeing mode to obtain the product with gradually changed surface color is achieved, and the technical problem that the gradually changed color on the surface of the product is generally realized by gradually changing spraying in the prior art, but the overall appearance effect of the gradually changed color generated by the gradually changing spraying mode is poorer is solved, so that the technical effect of improving the overall appearance effect of the gradually changed color on the surface of the product is realized.

It should be noted that the light-shielding paint is generally gray paint or black paint, and the target product is made of transparent material, so that the light transmission of the target product can be prevented by spraying the light-shielding paint.

After the application of the light-shielding paint, a white paint is applied to the intermediate product.

In addition, after the target product is obtained by spraying the white paint, the target product needs to be cleaned and then dyed.

In the embodiment of the present invention, as shown in fig. 2, after obtaining the intermediate product, the method further includes the following steps:

step S23, engraving a target pattern on the intermediate product so that light can transmit through the target pattern.

In the embodiment of the invention, after the intermediate product is obtained, the target pattern can be laser-etched on the surface of the intermediate product through the red light laser etching machine or the violet light laser etching machine, so that light can penetrate through the target pattern.

The target pattern may be a graphic pattern or a character pattern.

In the embodiment of the present invention, after obtaining the target product, the method further includes the following steps:

In addition, the second target area may be any area of the target product except the first target area (i.e. an area of the target product that does not need to be dyed), and a protective layer may be disposed on the second target area to prevent the second target area from being accidentally dyed during the dyeing process of the first target area.

The protective layer may be provided on the second target area by wrapping the sealing material on the second target area, spraying an ink protective layer on the second target area, or the like.

Preferably, the protective layer is provided by spraying an ink protective layer on the second target area.

The following two methods for manufacturing the gradual change color of the housing of the electric toothbrush are specifically proposed.

The method comprises the following steps:

1, obtaining the shell of the electric toothbrush by using a transparent plastic raw material and an injection molding mode.

2, spraying gray or black shading paint on the surface of the shell of the electric toothbrush to obtain an intermediate shell.

And 3, engraving a target pattern on the middle shell by utilizing a red light laser engraving machine or a purple light laser engraving machine so as to enable light generated when the movement of the electric toothbrush is lightened to pass through the target pattern.

And 4, after the target pattern is carved on the middle shell, spraying white paint on the middle shell to obtain the target shell, wherein the target pattern can still normally transmit light after the white paint is sprayed.

Before dip-dyeing the target shell, the target shell can be cleaned and dried by ultrasonic waves, then the target shell is immersed in a dye liquor tank for 3-6 minutes, the dye liquor consists of toner and liquid medicine, the temperature of the dye liquor is controlled within the range of 60-90 ℃ (the specific temperature is within the accurate range of further controlling the temperature of the dye liquor according to the selection of a PC material or an ABS material), then the target shell is taken out and rinsed for 10-15 minutes by clear water, then the target shell is cleaned and dried by ultrasonic waves (a common dryer can be used), the drying temperature is about 50-60 ℃, and the drying time is about 10-15 minutes.

It should be noted that different dye liquor formulas can be selected for different colors, and the depth of the surface color of the target shell and the gradual change of the same color or the transitional gradual change among different colors can be realized according to the length of the dip dyeing time and the up-down lifting of the target shell.

For example, the same color shading gradual change can be realized by changing the dip dyeing time of the target shell and changing the region of the target shell immersed in the dyeing solution by lifting the target shell up and down, different color gradual changes are realized by firstly dip dyeing a certain end region of the target shell and then dip dyeing the other end region of the target shell by the same method, and the specific region size and position can be controlled by the target shell according to the preset condition requirements and can be changed by lifting the target shell up and down to change the region of the target shell immersed in the dyeing solution), so as to achieve the required single-color or multi-color gradual change effect.

When a partial area of the target housing does not need to be impregnated or is not required to be impregnated with a certain dyeing solution, protective ink can be sprayed on the surface of the partial area before the target housing is impregnated, so that the partial area is prevented from being impregnated accidentally.

And 6, spraying a protective paint surface on the surface of the finish-impregnated target shell, thereby obtaining a final finished product (namely, the shell of the electric toothbrush with the gradually changed surface color).

The second method comprises the following steps:

2, before dip-dyeing the shell of the electric toothbrush, the shell of the electric toothbrush can be cleaned by ultrasonic waves and dried, then the shell of the electric toothbrush is immersed into a dye liquor tank for 3-6 minutes, the dye liquor consists of toner and liquid medicine, the temperature of the dye liquor is controlled within the range of 60-90 ℃, then the shell of the electric toothbrush is taken out and rinsed by clear water for about 10-15 minutes, then the shell of the electric toothbrush is cleaned by ultrasonic waves and dried (a common dryer can), the drying temperature is about 50-60 ℃, and the drying time is about 10-15 minutes.

It should be noted that different dye liquor formulas can be selected for different colors, and the shade of the surface color of the shell of the electric toothbrush and the gradual change of the same color or the transitional gradual change among different colors can be realized according to the length of the dip-dyeing time and the vertical lifting of the shell of the electric toothbrush.

For example, the same color shade gradual change can be realized by changing the dip dyeing time of the shell of the electric toothbrush and changing the region of the shell of the electric toothbrush, which is immersed in the dyeing solution, by lifting the shell of the electric toothbrush up and down, different color gradual changes are realized by first dip dyeing a certain end region of the shell of the electric toothbrush and then dip dyeing the other end region of the shell of the electric toothbrush by the same method, and the specific region size and position can be controlled by the shell of the electric toothbrush according to the preset condition requirements and can be changed by lifting the shell of the electric toothbrush up and down to change the region of the shell of the electric toothbrush, which is immersed in the dyeing solution), so as to achieve the required single-color or multi-color gradual change effect.

And 3, spraying a protective paint surface on the surface of the shell of the finished dip-dyed electric toothbrush to protect the gradient dyeing layer.

4, after the protective paint surface is sprayed, spraying gray or black shading paint on the inner surface of the shell of the electric toothbrush.
