AI Technical Summary

Technical Problem

Existing heat shrink tubing for sealing cigar filters cannot determine a reasonable heating temperature range, leading to overheating and affecting installation stability.

Method used

A temperature-sensitive color-changing zone is set in the sealed heat shrink tubing. The color change after heating indicates the appropriate heating temperature. Combined with the installation structure of the heat shrink tubing and the mouthpiece fixing part, it ensures that the installation is secure at the appropriate temperature.

Benefits of technology

By observing the color change of the temperature-sensitive color-changing zone, users can understand the appropriate heating temperature range, ensuring the secure installation of the sealed heat shrink tube at the mouthpiece fixing part and avoiding overheating.
