Description

Technical Field

[0001] This utility model belongs to the field of electro-etching pen technology, specifically a combinable electro-etching pen. Background Technology

[0002] An electro-etching pen is a tool that uses electrical energy to drive mechanical vibration or heat to write, mark, or etch on the surface of various materials. It is widely used in industrial manufacturing, handicraft processing, and personalized customization. Its core principle is to convert electrical energy into mechanical energy or heat energy, and then use the pen tip to physically act on the surface of the material to form permanent marks.

[0003] Most existing electro-etching pens adopt an integrated structure, encapsulating the power module, power supply module, and control module within the pen body. While this design simplifies the assembly process, it has significant drawbacks. When a module malfunctions, the user needs to disassemble the entire pen for repair, resulting in high repair difficulty and cost. To address this issue, some electro-etching pens adopt a split design with threaded connections between the components. However, vibrations during use can cause these threaded connections to loosen, hindering their operation.

[0004] Secondly, electro-etching is a delicate process, and insufficient light can easily affect the operation, making it difficult to clearly observe the etched area. This can easily lead to problems such as etched deviations and uneven depths, which not only reduces work efficiency but may also cause material waste and increased costs.

[0005] Therefore, a modular electro-etching pen is proposed to address the above problems. Utility Model Content

A heat-absorbing sleeve 7 is provided on the outside of the upper pen shell 1, and the lower end of the heat-absorbing sleeve 7 extends to the lower pen shell 2. The inner wall of the heat-absorbing sleeve 7 is provided with evenly distributed positioning protrusions 8 near the upper and lower ends. Positioning grooves 9 are provided on the outer walls of the upper pen shell 1 and the lower pen shell 2 at positions corresponding to the positioning protrusions 8. The structure of the positioning protrusions 8 and the positioning grooves 9 can prevent the upper pen shell 1 and the lower pen shell 2 from rotating relative to each other, thereby avoiding loosening. An anti-slip sleeve 10 is fitted on the outside of the lower pen shell 2, and an illumination component 11 is connected to the lower end of the outer side of the anti-slip sleeve 10.

[0032] Specifically, the top of the upper pen shell 1 is connected to a cover plate 13 via a connecting shaft 12. A first magnetic adsorption strip 14 is provided on the top surface of the upper pen shell 1, and a second magnetic adsorption strip 15 is provided on the cover plate 13 at a position corresponding to the first magnetic adsorption strip 14. By opening the cover plate 13, the battery 3 can be charged through the charging port 16.

[0033] Furthermore, a charging port 16 is installed on the top surface of the battery 3 to charge the battery 3.

[0034] Furthermore, the heat-absorbing sleeve 7 includes a ring 701 whose inner wall is tightly attached to the outer wall of the pen shell 1. A cavity 702 is provided inside the ring 701, and a coolant 703 is provided inside the cavity 702. The coolant 703 can absorb heat and assist the electro-etching pen in dissipating heat.

[0035] It is worth noting that a liquid injection port 704 and a liquid drain port 705 are respectively provided on one side of the ring 701 near the top and bottom. Both the liquid injection port 704 and the liquid drain port 705 are connected to the cavity 702, which facilitates the replacement of the coolant 703. Furthermore, the liquid injection port 704 and the liquid drain port 705 can be replaced with an inlet connector and an outlet connector, respectively. The inlet connector is connected to the corresponding delivery pump, and the delivery pump is connected to the coolant 703 at a low temperature through a pipeline.

The universal rod 1102 can adjust the direction of the light source in real time according to the writing angle, pen tip position, and light obstruction, ensuring that the light is always focused on the writing point and eliminating shadows caused by the hand or pen body. The universal rod 1102 is connected to a miniature LED light 1103, which can supplement the light and facilitate work.

[0038] It is worth emphasizing that a positioning groove 1104 is provided at the lower end of the outer side of the anti-slip sleeve 10, and a positioning ring 1101 is provided in the positioning groove 1104.

[0040] Working principle and process: First, the electro-etching pen adopts a split structure, allowing for the replacement of different batteries 3 and power modules 4 as needed. Second, the positioning protrusions 8 on the inner wall of the heat-absorbing sleeve 7 extend into the positioning grooves 9 on the outer walls of the upper pen shell 1 and the lower pen shell 2, respectively, preventing the upper pen shell 1 and the lower pen shell 2 from rotating relative to each other due to vibration, thus avoiding loosening. Finally, the structure of the heat-absorbing sleeve 7 can absorb some heat during operation, facilitating better operation of the electro-etching pen. The liquid inlet 704 and the liquid outlet 705 can be replaced with an inlet connector and an outlet connector, respectively. The liquid connector is connected to the corresponding delivery pump, which is connected to the low-temperature coolant 703 through a pipe. The liquid outlet connector is connected to a container to collect the hot coolant 703, so that circulation cooling can be achieved during operation. The lighting component 11 solves the pain point of traditional electro-etching pens in low-light environments. The universal rod 1102 supports the free rotation and positioning of the miniature LED light 1103. Users can adjust the direction of the light source in real time according to the writing angle, pen tip position and light obstruction, to ensure that the light is always focused on the writing point and eliminate shadows caused by the hand or pen body.
