An improved Q-style aroma diffuser, relating to the technical field of aroma diffusers, comprising a main housing and a perfume bottle assembly. A heater fixing base (1) is mounted inside the main housing. One end of the heater fixing base (1) is provided with a connecting cavity (2), and the other end is detachably equipped with a heater (3). The heater fixing base (1) is provided with a PCB assembly (5). Two sides of the heater are both provided with electrodes (6) in contact and conduction with the PCB assembly (5). The perfume bottle assembly comprises a bottle body (4) and a cotton bar (7). The bottle body (4) is connected to the connecting cavity (2). One end of the cotton bar (7) extends out of the opening of the bottle body (4) and extends into the heater (3). The main housing is provided with a fragrance dispersion region (8), and the main housing is further provided with a rotatable plug base (9). A conductive copper sheet (10) is provided inside the main housing. One end of the conductive copper sheet (10) is in contact and conduction with the rotatable plug base (9), and the other end is in contact and conduction with the PCB assembly (5), in order to achieve high assembly efficiency and facilitate automated production. The aroma diffuser can effectively maintain a constant temperature, and can effectively keep the product horizontally inserted into the socket, thereby preventing the perfume from flowing out.L'invention concerne un diffuseur amélioré d'arôme de type Q, se rapportant au domaine technique des diffuseurs d'arômes, comprenant un boîtier principal et un ensemble bouteille de parfum.
