Automatic hair dryer

Abstract

An automatic hair dryer includes a base, a movable arm mounted on the base, a hair dryer head at the end of the movable arm, a sensor mounted on the hair dryer head, an air delivery unit, and a control unit connected to each component. By acquiring information on hair distribution, humidity, or hair texture from the sensor, the control unit can automatically drive the movable arm to perform multi-axis displacement and angle adjustment, and simultaneously control the airflow speed and temperature of the air delivery unit. The hair dryer head also includes a hair care unit, with its spray nozzle aligned side-by-side with the air delivery unit to synchronously output atomized liquid, and a display unit allows the user to monitor the device's status. This invention overcomes the shortcomings of conventional devices that cannot dynamically adjust according to hair dryness and humidity, achieving both even drying and simultaneous hair care.

Claims

1. An automatic hair dryer, comprising: a base; a movable arm disposed on the base; a hair dryer head disposed at the end of the movable arm; a sensor disposed on the hair dryer head; an air delivery unit disposed on the hair dryer head; and a control unit connected to the movable arm, the sensor, and the air delivery unit, wherein the control unit controls the movable arm to move the hair dryer head and controls the air delivery unit to deliver air toward the user's head based on hair-related information obtained by the sensor.

2. The automatic hair dryer as described in claim 1, wherein the hair-related information is hair distribution information, and the sensor includes an infrared ranging module or an image recognition lens.

3. The automatic hair dryer as described in claim 1, wherein the hair-related information is hair humidity information or hair quality information, and the sensor includes an infrared temperature sensor or a spectral sensing module.

4. The automatic hair dryer as claimed in claim 1, wherein the hair dryer head is further provided with a hair care unit, the hair care unit including a reservoir for containing hair care liquid and an atomizer communicating with the reservoir, the atomizer being an ultrasonic oscillating plate or a microporous atomizing plate.

5. The automatic hair dryer as claimed in claim 1, wherein the movable arm is a multi-axis robotic arm structure, comprising at least one arm segment, at least one movable joint, and at least one drive element and a transmission mechanism disposed inside the movable arm or at the movable joint, wherein the drive element is a stepper motor or a servo motor.

6. The automatic hair dryer as claimed in claim 5, wherein the drive element is controlled by the control unit to change the bending or rotation angle of the movable joint, thereby driving the hair dryer head to make multi-directional position and angle adjustments in three-dimensional space.

7. The automatic hair dryer as described in claim 1 further includes a display unit for displaying a hair drying mode, a device status, or operation information.
