Technologies are generally described for air freshener devices. The devices may comprise an insertion section including electrodes. The electrodes may be effective to receive and conduct an electric current and to secure the devices to an electric source. The devices may include a base. The base may be attached the insertion section. The base may include a port effective to receive at least part of the electric current from the electrodes. The base may include a collar effective to apply heat sufficient to release a fragrance from a material infused with the fragrance when at least part of the electrical current is supplied to the collar from the electrodes. The device may include a cap. The cap may have a ring shaped cross-section and may be sized and shaped so as to be connectable to the base such that the port is accessible when the cap is connected.本案總體上係描述用於空氣清新器裝置之技術。該等裝置可包含具有電極的插入區段，該等電極可有效地接收且傳導電流，且將該等裝置緊固至電源。該等裝置可包括基座。該基座可附接該插入區段。該基座可包括一埠，該埠有效地自該等電極接收該電流之至少一部分。該基座可包括一軸環，當該電流之至少一部分自該等電極供應至該軸環時，該軸環有效地施加足夠的熱而由以芳香劑浸漬的材料釋放該芳香劑。該裝置可包括一罩蓋，該罩蓋可具有環形橫截面，且經設定尺寸並成形以便可連接至該基座，而使得當該罩蓋被連接時，該埠為可進入的。
