Advertising terminal for promoting smell combination device to release fragrance by using light-emitting diode (LED) heat

Abstract

The invention discloses an advertising terminal for promoting a smell combination device to release fragrance by using LED heat. The advertising terminal comprises an LED light box of a product advertising playing terminal and a playing system control circuit. A set of smell combination device is arranged on the rear portion of the LED light box. The smell combination device is composed of a heat absorption circulation unit, a heat storage unit, a rotation heating unit and a perfume combination release mechanism. According to the advertising terminal, the smell combination device formed by combination of different perfume basic unit boxes is arranged on the rear portion of the LED light box, heat generated by LED emitted light is absorbed by the heat absorption circulation unit, perfumes in the perfume basic unit boxes corresponding to advertising contents in the perfume combination release mechanism are heated through the heat storage unit and the rotation heating unit, and fragrance of the perfumes is released by smell release ports, and during advertising playing, watchers can obtain visual and auditory experiences and truly feel fragrance identical to the advertising contents, so that a smell experience is obtained, and the degree of awareness of the advertising contents is increased.
