Description

Technical Field

[0001] The utility model relates to the technical field of fragrance appliances, in particular to a fragrance machine. Background Art

[0002] At present, the fragrance machines on the market usually use a magnetic suction structure to fix the fragrance bottle. The specific method is to place the iron parts at the bottom of the fragrance bottle cap, and then use the magnet fixed on the fragrance generator to fix it. However, this fixing method has some obvious defects. First of all, it is necessary to fix the magnet on the fragrance generator, which not only increases the complexity of design and manufacturing, but also needs to consider the fixing method of the magnet. In addition, in order to achieve a reliable fixing effect, the magnet usually needs to be made into a special shape, which undoubtedly increases the production cost and manufacturing difficulty of the magnet. Therefore, the fragrance bottle fixing solution needs to be improved in terms of cost and manufacturing process, and most of the existing fragrance machines still manually operate the opening and closing of different fragrance outlets to release fragrance when changing fragrance, which will invisibly reduce the practicality of the fragrance machine.
