Abstract: A buckle structure for shaver head, the feature is that the connector base is formed with a mounting slot, the sidewall of the mounting slot is at least formed with two corresponding grooves; the connector is formed with an annular mounting boss, the annular mounting boss is adapted to the mounting slot, and inserted in the mounting slot, the sidewall of the annular mounting boss is formed with a mounting hole corresponding to the groove, the mounting hole is provided with a ball, and the connector is provided with an elastic piece which drives the ball to be partially exposed out of the mounting hole to clamp the groove. The advantage is that based on the buckle structure of elastic piece and ball, during assembly and disassembly, the ball rolls, the wear is reduced, the service life is long, and the assembly and disassembly are easier.

Abstract: An injector for co-feeding liquid and solid fuels into a gasifier is provided. The injector includes a body, a first member, and a second member. The body comprises a first channel for conveying a liquid fuel. The first member surrounds the body to define a second channel for pneumatically conveying a solid fuel. The second member surrounds the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel. The liquid fuel is atomized before being mixed with the solid fuel. A method for co-feeding liquid and solid fuels is also presented.
