Claims

[Scope of utility model registration request]

A syringe body, a cylindrical handle attached to the rear end of the syringe body, and an inner flow path and an outer flow path comprised of a small diameter tube and a large diameter tube coaxially attached to the tip of the syringe body. and a nozzle with a double pipe structure formed in the syringe body, the water and air from the water pipe and the air pipe arranged in the cylindrical handle are opened and closed by a valve provided in the syringe body. The water in the water supply channel is ejected from the tip of the nozzle part through one channel of the nozzle, and the air in the air supply channel is sent to the other flow channel of the nozzle part through the swirling flow nozzle. A swirling flow is generated in the passageway, and an outer high-temperature airflow is ejected from the tip of the nozzle part, and one end of the inner low-temperature backflow airflow is communicated with an exhaust passage and an exhaust passage provided in the syringe body, and the other end is connected to the above-mentioned cylindrical handle. A dental syringe characterized by discharging low-temperature backflow air to the outside of a cylindrical handle using an externally disposed exhaust pipe.
