The application provides a self-catalytic reformer based on a 3D printing technology and a manufacturing method thereof, and the method comprises the following steps: S1, respectively taking nickel-based alloy powder and / or iron-based alloy powder and nickel-aluminum alloy powder, mixing the powders uniformly in a mixing device to obtain printing powder; S2, using three-dimensional drawing software to obtain a shell structure with a reserved cavity; S3, using porous design software to obtain a porous structure, and the porous structure is matched with the reserved cavity of the shell structure; S4, 3D printing the self-catalytic reformer: taking the printing powder in step S1 and adding the powder into a powder supply bin of a 3D printer, then respectively taking the shell structure in step S2 and the porous structure in step S3 and introducing the structures into the 3D printer, and using 3D printing technology to print an integrally formed self-catalytic reformer. The self-catalytic reformer is obtained by the above method. The structure and function are integrated, no additional catalyst is needed, the catalytic efficiency is improved, and the production cost is reduced.

The utility model provides a kind of humanoid robot leg and joint unit, the joint unit includes motor, the motor is provided with output shaft and shell;Its characterized in that, the rear portion of the shell is provided with the first mounting site of installing first bearing, the shell is also provided with second mounting site, and the second mounting site is used to connect with the drive object of the motor.This utility model, power itself body is as the axle body of sleeve bearing, can weaken the reaction force that the drive object in the lower part of joint unit is received in movement through bearing, shell and the like multiple isolation structures, at least most is borne by bearing, can effectively protect motor shaft and the transmission structure inside motor, improve the stability and service life of joint component, and have integrated structure.

The invention discloses a hose assembly, a hose and a preparation method, and relates to the technical field of hose connection. The hose assembly comprises a hose body and a connector which are coaxially arranged; the connector comprises a connector piece, an inner core and a sleeve. The connector piece is provided with a connector through hole, the first end of the inner core is communicated with the connector through hole, and the second end of the inner core is sleeved with the sleeve. A sleeve convex groove, a sleeve protrusion and a sleeve boss are sequentially arranged on the inner circumferential face of the sleeve in the first direction. An inner core groove, a limiting protrusion, a first inner core protrusion and a second inner core protrusion are sequentially arranged on the outer circumferential face of the inner core in the first direction. When the hose body is arranged between the outer circumferential face of the second end of the inner core and the inner circumferential face of the sleeve in a sleeved mode, the sleeve convex groove is clamped into the inner core groove, the sleeve protrusion and the first inner core protrusion are meshed in a staggered mode, and the sleeve boss and the second inner core protrusion are meshed in an aligned mode. According to the technical scheme, the structures of the hose body, the inner core and the sleeve tend to be integrated, and deformation of all parts of the hose assembly under high pressure and ultrahigh pressure is avoided.

The invention provides a fire alarm mycelium material and a preparation method and application thereof, and belongs to the technical field of fire alarm materials, and the fire alarm mycelium material comprises hemp stalks, ganoderma lucidum, ethanethiol and the like. The preparation method of the mycelium material comprises the following steps: carrying out mixed culture on a hemp stalk culture material and ganoderma lucidum; dissolving polyvinyl alcohol and lauryl sodium sulfate in deionized water; adding ethanethiol and polymethyl methacrylate into an organic solvent; dropwise adding the water phase into the oil phase, and emulsifying to obtain ethanethiol microcapsules; and mixing the pure mycelium material with ethanethiol microcapsules, culturing, and demolding to obtain the fire alarm mycelium material. According to the invention, intrinsic integration of a material structure and an early warning function is realized through a mycelium biological assembly and microcapsule embedding and fixing technology, so that the material becomes a sensing unit. According to the material, rapid and active fire early warning without external energy is realized by utilizing the temperature-triggered fracture characteristic of the microcapsules and the extremely low odor threshold value of ethanethiol.
