<p>An electronic alarm clock providing negative ions for air purification and providing natural illumination comprises a negative ion generator (1), a fan (2), an LCD display screen (3), a circuit board (4, 5, 7) and a blue light lamp (6). The negative ions produced by the negative ion generator (1) are blown to the blue light illuminated air by the fan (2) blowing wind. The negative ion generator (1) is located in the middle-lower part of the left half part of the main body. The fan (2) is set at the back of the negative ion generator (1). The upper part of the fan (2) is arranged in a hollow manner. The blue light refreshing function and the negative ion purification technique are combined in the electronic alarm clock. And the produced negative ions are effectively distributed in the blue light illuminated space according to the scientific structural design, by which air purifying functions such as sterilization, dust removal, smoke abatement, and odor removal are realized. Therefore the refreshing effect of the blue light has been enhanced and the mental state and temper can be improved. Functions of a clock and a perpetual calendar are also provided to make a user easy to record, thus the multifunction and practical applicability are realized.</p> |
