Abstract: The present disclosure relates to the field of head-mounted equipment and discloses an air conditioning device of virtual reality (VR) head-mounted equipment. The air conditioning device includes a forehead-mounted piece configured to be worn on the forehead of the head of a user. By the arrangement of the air exchange fan inside the inner cavity, an effect of air circulation between the forehead of the user and an external air flow is achieved, so that effects of heat dissipation, ventilation, and air exchange are achieved; and stuffiness and lens fogging difficultly occur.
