The invention relates to a diffuser bottle and a diffuser structure, which firstly introduces powder metallurgy technology into the diffuser field. The main system is: a powder diffuser is die-cast by powder metallurgy technology. The diffuser rod has a fixed hole at the top and an upper end. Positioning flange； a bottle body having an upper joint portion and a lower joint portion； a base, the bottom of the base is closed, and is fixedly connected with the lower joint portion, and a hollow convex post is provided in the center for the fragrance stick to be inserted Positioning； a positioning ring having a perforation, the positioning ring passing through the diffuser stick, and a fixed connection with the upper joint； a cover, the middle of the cover has a perforation, and a locking member passes through the upper cover Perforate and lock the upper cover with the diffuser stick. In this way, the effect of the diffuser stick is not afraid of falling dust and mildew, the diffuser bottle is not afraid of falling, and it is convenient to open and close for storage and use.本發明係一種擴香瓶及其擴香結構，首創將粉末冶金技術帶入擴香領域，主要係：一以粉末冶金技術壓鑄而成擴香棒，該擴香棒頂端具有固定孔，上端具有定位凸緣；一瓶身，該瓶身具有上接合部及下接合部；一底座，該底座底部為封閉，與該下接合部產生固接，中心具有中空凸柱，供該擴香棒插入定位；一定位環，該定位環具有穿孔，該定位環穿過該擴香棒後，與該上接合部產生固接；一上蓋，該上蓋中間具有穿孔，由一鎖固件穿過該上蓋之穿孔，將上蓋與擴香棒鎖固。如此設計，可達到擴香棒不怕落塵發霉、擴香瓶不怕傾倒、方便開合收納使用的功效。
