Air path structure of convection toughening furnace

The utility model discloses an air path structure of a convection toughening furnace, which relates to the technical field of glass production devices, and comprises a furnace body, a first heating component and a second heating component, a first heating pipe and a second heating pipe in the first heating component and the second heating component of the device share the same air pipe with a heating pipeline; therefore, in the air path circulation process, the electric heating wire can achieve the purpose of heating internal air by heating the first heating pipe and the second heating pipe, the air is heated more uniformly and quickly, the time for independently checking and maintaining the heating pipes and the air pipe is saved, and the working efficiency is improved. The first heat collecting pipe and the second heat collecting pipe can collect hot air flowing out of the furnace body in the heating process of the glass body, so that lost hot air can be effectively collected and utilized, the first heating
