This invention relates to the field of medical
assistive device technology, and proposes a sleep aid device for
neurology, comprising: a water filling section, which includes a
water storage mechanism for holding
clean water; a sound generating section, which includes a sound amplification mechanism, a drive mechanism, a water droplet emitting mechanism, a fan wheel, a rotating base, and a vibrating plate for emitting sleep-aiding sounds; and a drive section, which includes a fragrance storage mechanism and a
timer speed adjustment mechanism for driving the drive source of the drive mechanism in the sound generating section. Through the coordination of the
timer speed adjustment mechanism, the drive mechanism, and the water droplet emitting mechanism, different white noises can be generated, and the
white noise produced by raindrops falling on different materials due to changes in
wind direction can be simulated. This allows patients to continuously listen to the realistic
white noise simulating raindrops falling on different materials to fall asleep, avoiding the situation where some patients are insensitive to electronic sounds played by a player, resulting in
poor sleep aid effects.
