On September 4th, the torch of the Hangzhou Asian Games was officially delivered in Ningbo, Zhejiang Province. More than 2000 torches were loaded onto trucks and transported to 11 cities in Zhejiang Province, and the highly anticipated Hangzhou Asian Games torch relay event is ready.

The relevant person in charge of the Hangzhou Asian Games Organizing Committee introduced that the overall height of the torch is 730 millimeters, with a net weight of 1200 grams. The color of the upper part is "Dan Gui Jin", which gradually changes from the "waistline" to the theme color of the Asian Games, "Rainbow Rhyme Purple". The overall design concept of the torch comes from the Liangzhu culture, which demonstrates the 5000 year history of Chinese civilization.

From a structural perspective, the torch is divided into multiple parts from top to bottom, including the outlet, torch crown, torch body, and torch base. The design of the fire outlet originates from the earliest oracle bone script shape of "Cong", which means "light starts from the inner circle"; The torch crown is characterized by the meaning of jade cong, blending square and circle, standing proudly; The body of the torch is evolved from the spiral pattern of Liangzhu, resembling fingerprints, naturally interwoven, exquisite and delicate; Juji, on the other hand, has eight water veins as the veins of civilization, representing the eight major water systems in Zhejiang.

"The name of the torch, 'Yanhuo', itself contains the meaning of 'inheritance'." Wang Yun, the director of the torch design and director of the Industrial Design and Research Institute of the Chinese Academy of Fine Arts, said that the overall contour curve of the torch is like holding firewood, emitting a sense of power and convergence from the outside in the midst of movement and stillness, with a style that is peaceful, elegant and atmospheric. ".

In addition to the "firewood" torch, the extension materials for the torch include flame collectors, flame rods, spark pots, spark lamps, spark boxes, ignition rods, spark light boxes, torch brackets, etc., all of which were designed and completed by the team of the Industrial Design and Research Institute of China Academy of Fine Arts.

The reporter learned that the research and development and manufacturing of torches have gone through two years, and the technical team is composed of five teams, each specifically responsible for torch structure design, process treatment, product testing, production manufacturing, and quality control. In order to ensure the stability of torch combustion, the team carried out a special breakthrough in the combustion system around four independently developed combustion technologies: direct injection flame stabilization technology, dense cluster net combustion technology, large hole diversion rainproof technology, and double jet mixing technology.

For example, the direct flame stabilization technology can allow the direct flame to burn below the circular main flame and reignite it after the main flame of the torch is accidentally extinguished. The dual jet mixing technology can make the inner ring direct flame mixing more uniform, with a short and powerful flame that is not affected by external environmental interference. These technologies have all improved the wind resistance of the torch.

Yu Yu, the technical director of the torch project, told reporters that in order to minimize the impact of extreme weather such as rainstorm, the torch dense network was designed to effectively prevent rainwater blockage through large holes and small holes. The large hole diverts rainwater, while the small hole prevents rainwater from falling and blocks the nozzle, greatly improving the rainproof performance of the torch.

"After repeated testing, our staff has compiled a total of 26 test instructions and issued over 60 test reports, breaking through multiple technical bottlenecks in the fields of technology, materials, and production." Yu Yu said that currently, the torch can continue to burn under wind speeds of 8 levels and heavy rain, and the flame is clearly visible. The torch has broken multiple records in terms of wind resistance, high temperature resistance, and other aspects. "We strive to achieve the ultimate quality of every Asian Games torch."
