Description

Technical Field

[0001] The utility model relates to the technical field of spray heads, in particular to an adjustable spray head for spraying a stylus pen shell. Background Art

[0002] As we all know, a stylus pen is an input tool for touch screen devices. It can replace fingers for precise operations. Usually, the stylus pen can interact with the screen through capacitance or electromagnetic induction technology to achieve precise writing, drawing, clicking and other operations. Usually, a nozzle is required when spraying the shell of a spray pen. A nozzle refers to a device for spraying liquid or gas.

[0003] However, traditional nozzles for spraying stylus shells can usually only use a single color of paint and cannot adjust the switching of multiple colors, which limits the flexibility in painting or other applications that require multiple colors. In addition, with traditional nozzles for spraying stylus shells, the pigments are easily stratified inside the stylus shell, and the heavier pigments will settle at the bottom, while the lighter pigments will float on top, which will result in uneven color when spraying. Therefore, technical improvements are urgently needed. Utility Model Content
