Abstract: A laptop keyboard structure includes a keycap assembly and a key shaft assembly. The keycap assembly includes a keycap positioning plate, a plurality of stroke limiting structures and a plurality of keycaps. The stroke limiting structures are respectively disposed on the keycap positioning plate. The keycaps are respectively connected to the stroke limiting structure. The key shaft assembly, detachably assembled to one side of the keycap assembly, includes a circuit substrate and a plurality of key switches. The key switches are disposed on the circuit substrate and used to abut the keycap. A manufacturing method of the laptop keyboard structure is mainly to prepare the keycap assembly first, then to prepare the key shaft assembly, and finally to mount detachably the key shaft assembly to the keycap assembly by having the key switches respectively to penetrate the switch and further abut the keycap.

Abstract: A thermal cracker device includes an outer furnace and a thermal cracking furnace accommodated in the outer furnace. The outer surface of the thermal cracking furnace and the inner surface of the outer furnace define a space. The outer surface of the thermal cracking furnace has a fin structure to define an air flow channel in the space.
