AI Technical Summary
Technical Problem
Existing portable hot melt glue guns tend to drip from the nozzle after use, and have low heating efficiency, failing to effectively heat the glue stick both inside and out simultaneously.
Method used
The design combines a segmented melting mechanism with a leak-proof vacuum mechanism, heating the glue rod both internally and externally simultaneously, and preventing glue leakage through the vacuum mechanism. The design includes a preliminary preheating, segmented melting, and glue dispensing nozzle structure.
Benefits of technology
It improves heating efficiency, prevents colloid dripping, and enhances the cleanliness of the operating environment.

Abstract
This invention provides a portable hot melt adhesive rapid heating device, including a preliminary preheating mechanism, a segmented melting mechanism, a dispensing nozzle, and a leak-proof vacuum mechanism. The leak-proof vacuum mechanism is installed on the circumferential surface of the preliminary preheating mechanism, and the segmented melting mechanism is installed on its front end face. The dispensing nozzle is also installed on the front end face of the segmented melting mechanism. This design solves the problems of dripping hot melt adhesive after use, which is inconvenient and requires external heating, resulting in low heating efficiency. This invention has a reasonable structure; through the cooperation of the segmented melting mechanism and the leak-proof vacuum mechanism, it can simultaneously heat and melt the inside and outside of the adhesive stick, effectively improving the heating efficiency and preventing leakage from the dispensing nozzle after dispensing, thus improving the cleanliness of the usage environment.
