TECHNICAL FIELD
[0001] The utility model relates to dental medical instrument technical field, concretely is a kind of temperature sensing structure of hot melt dental adhesive gun. BACKGROUND
[0002] Hot melt dental adhesive gun is a tool for dental treatment, mainly used for dental adhesive filling in root canal treatment. When filling dental adhesive, hot melt dental adhesive gun needs accurate temperature control to monitor the temperature of dental adhesive, so that the dental adhesive does not deteriorate due to overheating, and the dental adhesive can be fully melted to a certain temperature. If the temperature control and monitoring are not accurate, it may cause root longitudinal crack or other damage. At present, the thermocouple and glue loading cylinder of hot melt dental adhesive gun are of one-piece structure, and the thermocouple directly senses the temperature of the glue loading cylinder. However, this may cause the glue loading cylinder and the whole machine to be integrated, resulting in more heat being transferred to the machine and causing heat loss. If the thermocouple and the glue loading cylinder are designed separately, the glue loading cylinder can be fully separated from the whole machine, reducing heat loss. However, the existing hot melt dental adhesive gun cannot sense the temperature or cannot accurately sense the temperature when the glue loading cylinder is separated from the whole machine. SUMMARY
