Description

Technical Field

[0001] The invention belongs to the field of pyrography pens, in particular to a pyrography pen capable of real-time temperature monitoring and a temperature control method thereof. Background Art

[0002] As an ancient and unique art form with a long history, pyrography art creates patterns and textures on the surfaces of various materials using high-temperature tools, showing a unique artistic charm. With the development of the times, pyrography art has gradually transformed from traditional manual skills to modern, professional tool-assisted creation. In the industrial field, operations such as material surface marking, repair, and processing also put forward requirements for high-precision heating tools. For example, in the manufacture and maintenance of electronic equipment, precise temperature control is essential for processes such as welding and plastic molding; in the pipeline installation and cable laying industry, reliable marking tools are needed to identify different pipes and cables to ensure the normal operation and maintenance of the system. These application scenarios have prompted the continuous evolution and innovation of the technology of tools such as pyrography pens.

[0003] Traditional pyrography pens mainly rely on simple heating devices, such as resistance wire heating, to indirectly control the temperature of the pen tip by adjusting the power supply voltage or current.

[0004] However, the traditional method has many limitations. First, the temperature control accuracy is low, which makes it difficult to meet the requirements of fine pyrography creation or high-precision industrial processing of different materials. Since it is impossible to accurately know the real-time temperature of the pen tip, users often need to rely on experience to judge whether the temperature is appropriate, which can easily lead to unstable quality of the work or defective products in industrial processing. Secondly, traditional pyrography pens lack an effective temperature monitoring and feedback mechanism. During use, safety problems may occur due to excessively high temperatures, such as scalding the user, causing a fire, etc., or the expected creation or processing effect cannot be achieved due to too low a temperature.
