In this embodiment, the upper end surface of the bin body 21 is recessed downward to form a sliding groove 211, the lower end surface of the bin cover 22 is provided with a protrusion 221 which is engaged with the sliding groove 211 in a downward protruding manner, and the protrusion 221 is slidably connected with the sliding groove 211, so that the sliding connection relationship between the bin cover 22 and the bin body 21 is realized. Further, the cross sections of the sliding groove 211 and the protrusion 221 are both in a "convex" shape, so as to prevent the protrusion 221 and the sliding groove 211 from being separated from each other, i.e., to realize the slidable snap-fit connection relationship between the bin cover 22 and the bin body 21. In addition, in order to enable the protrusion 221 and the sliding groove 211 to slide smoothly, the surface of the protrusion 221 is polished smooth.

In addition, referring to fig. 1 again, the bottom of the bin body 21 is provided with a discharge hole 212 communicated with the inner cavity of the bin body 21, and the discharge hole 212 is used for discharging the fire coal. Correspondingly, the bottom plate 11 is provided with a through hole 110 corresponding to the discharge port 212, the through hole 110 is communicated with the discharge port 212, and when in use, the fire coal in the bin body 21 sequentially passes through the discharge port 212 and the through hole 110 and then enters a combustion furnace (not shown) arranged below the bottom plate 11.
