This utility model discloses a magnet assembly structure for a pod-type electronic cigarette, comprising a cartridge and a main unit. The cartridge has a first groove at its bottom, into which a first magnet is embedded. A second groove is located at the bottom of the insertion cavity, into which a second magnet is embedded. The first and second magnets are magnetically attracted to each other. The first and second grooves have identical structures. The sidewall of the first groove has multiple raised ribs perpendicular to its bottom. One end of each rib near the groove opening is beveled, serving as a guide for the insertion of the first magnet. The first magnet is interference-fitted to the raised ribs. A gap is formed between the sidewall of the first magnet and the sidewall of the first groove, filled with glue, thus firmly bonding the first magnet to the first groove. Both the first and second grooves have protrusions at their bottoms, forming glue reservoirs, ensuring glue adhesion around the magnet and ensuring a secure and reliable magnet assembly.

This invention relates to the field of road engineering materials and solid waste resource utilization technology, specifically to basalt fiber reinforced coal gangue asphalt mixture, its preparation method, and its application. By weight, it comprises 100 parts activated coal gangue aggregate, 4-7 parts asphalt binder, 0.2-0.5 parts basalt fiber, 1-3 parts hydrated lime, and 0.3-1.5 parts silane coupling component. The coal gangue is calcined at 550-850°C to remove hydroxyl groups, transforming its surface into a slightly alkaline amorphous silica-alumina active surface. Utilizing the silica-alumina homology between the coal gangue and basalt fiber, the aggregate and fiber are covalently bonded at the contact interface via Si-O-Si and Si-O-Al bonds to form a continuously stressed aggregate-fiber-asphalt interface network. The hydrated lime provides anti-stripping, alkaline activation, and calcium node properties, achieving solid waste resource utilization while maintaining a freeze-thaw splitting strength ratio of over 90% and a dynamic stability of over 6000 cycles / mm.
