The invention discloses a
smoke generation section for constituting a
smoke generation
system. A tube body is formed by a plurality of cavity
pipe bodies which are coaxially superposed, wherein the cavity
pipe bodies have different
pipe diameters; the pipe bodies are constituted by slices which are connected end to end; and a plurality of heat
convection holes are formed in the slices. The
smoke generation section can be formed by the multiple pipe bodies which are superposed and can also be formed by the slices which are rolled; the
diameter of the tube body can be controlled by controlling the length of the slices in the rolling direction; through the multiple heat
convection holes, the
heat transfer efficiency between a
heating element and the smoke generation section and the
heat transfer efficiency inside the smoke generation section can be improved,
convective heat transfer is enhanced, and the smoke formation effect is improved; through arranged convex patterns, pores between every two adjacent
layers of slices can be increased, and thus large smoke channels are formed so as to achieve the better smoke formation effect and smoking feeling; according to the smoke generation section, smoke can be released in a center heating or center and periphery mixed heating mode; and the smoke generation section is simple in structure, few in preparation step, high in efficiency, rapid and convenient to operate and good in effect, and has very high practicability.
