[0002] The melting tin furnace is a commonly used melting tin equipment in the electronic manufacturing industry, which can quickly heat the tin material to a molten state and provide a stable melting tin environment. In the inductance production, the melting tin furnace can be used for welding the pins of the inductor or performing other operations that require melting tin.

[0003] The current melting tin furnace usually has a scraper for scraping the impurities floating on the surface of the tin liquid, but after the scraper scrapes the impurities to the edge of the furnace, some impurities will adhere to the scraper, which makes the scraper carry impurities into the tin liquid during subsequent use, thereby reducing the impurity removal effect. In addition, as the liquid level of the tin liquid gradually decreases, workers need to supplement it regularly, which increases the workload of the workers, and the addition of tin will cause the interruption of production, affecting the production efficiency. SUMMARY

[0004] The utility model aims at providing a melting tin liquid device with good impurity removal effect and automatic tin addition.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows.
