The mosquito repellent auxiliary device can be used with different types of mosquito repellent devices, and is mainly composed of a seat and a fan which can be assembled with each other. The seat has a plurality of connecting parts, and one of the plurality of connecting parts is connected with the mosquito repellent device, so that the fan can blow the air towards the mosquito repellent device to form the air supply flow, thereby, the air supply flow can speed up the mosquito repellent device. The flow speed of the surrounding air can further accelerate the volatilization speed of the internal agents of the mosquito repellent device, thus effectively shortening the time of mosquito repellent.本創作驅蚊輔助裝置能配合不同類型的驅蚊裝置使用,並主要由能相互組裝的座體以及風扇所構成,該座體具有複數個連接部,而複數個連接部其中之一與驅蚊裝置相互連接,使得風扇能將空氣朝向驅蚊裝置進行吹送以形成送風氣流,藉此,送風氣流能加快驅蚊裝置周遭空氣的流動速度,進而能加快驅蚊裝置內部藥劑的揮發速度,致使有效縮短驅蚊的時間。
