Alternative device of Soxhlet extractor

The utility model relates to an alternative device of a Soxhlet extractor. The alternative device comprises a condenser, an extractor and an extraction bottle, wherein a steam raising branch tube, which is communicated with a chamber and inclines downwards, is arranged on the side wall of the extractor; two connectors are arranged above the extraction bottle; one of the connectors is connected with the steam raising branch tube while the other connector is connected with the outlet of the extractor. According to the alternative device of the Soxhlet extractor, an original single-opening flask is changed into a two-neck bottle as the extraction bottle, the extractor with the steam raising branch tube and an extract return branch tube on two sides is adopted to replace an extractor with a siphon on the side surface, and thus the problems that the siphon on the extractor is likely to be blocked and broken, materials cannot be sufficiently soaked and the like in a conventional experiment are solved.
