Mist spraying hair brush with retractable bristles

A mist spraying hair brush with retractable bristles comprising:

• a housing having
• a containing space defined in the housing;
• a first casing having
• multiple through holes disposed through a side of the first casing, disposed at spaced intervals, and communicating with the containing space;
• a second casing assembled with the first casing, and the containing space defined between the first casing and the second casing;
• and
• a mounting hole disposed through the side of the first casing that the multiple through holes are disposed through, spaced apart from and surrounded by the multiple through holes, and communicating with the containing space;
• a brush body disposed in the containing space of the housing between the first casing and the second casing, moving linearly in the containing space, and having
• a base;
• and
• multiple bristles disposed at spaced intervals on a side surface of the base facing the first casing, and each one of the multiple bristles being capable of extending out of a corresponding one of the multiple through holes when the base moves toward the first casing;
• at least one restoring spring mounted between the housing and the base of the brush body;
• an actuating shaft being a single element, rotatably mounted to the housing, disposed in the containing space, and having
• a bended portion located between two ends of the actuating shaft and protruding radially;
• and
• a mist spraying assembly disposed in the containing space of the housing between the second casing and the actuating shaft, and having
• an oscillation assembly mounted in the mounting hole of the housing;
• and
• an injection portion disposed in the containing space of the housing, and communicating with the oscillation assembly, such that liquid flowing from the injection portion to the oscillation assembly is atomized into spray when the oscillation assembly is oscillating, and then the spray flows out of the housing via the mounting hole;
• wherein when the actuating shaft is rotated and the bended portion pushes the base of the brush body, the brush body moves linearly and each one of the multiple bristles extends out of the corresponding through hole;
• and
• elastic potential energy is stored in the at least one restoring spring when the bended portion pushes the base of the brush body, and when the bended portion leaves the base, the elastic potential energy is released to make the at least one restoring spring bounce to make the multiple bristles retract into the housing.
