Based on this, this application provides a cigarette machine structure 10 and range hood (not shown), and cigarette machine structure 10 and range hood can promote the fire prevention reliability.

Referring to fig. 1 and 2, a cigarette maker construction 10 in one embodiment comprises a cigarette maker assembly 100 and a switch assembly (not shown), the cigarette maker assembly 100 being provided with an air opening (not shown) for opening or closing the air opening. The switch assembly is configured to deform to open the air opening when the air temperature inside the cigarette machine assembly 100 is below a preset value, and to resume deformation to close the air opening when the air temperature inside the cigarette machine assembly 100 is above the preset value.

The air inlet can be the air inlet 1242 or the air outlet 112. The quantity of wind gap is a plurality of, for example, one of them can possess the air inlet function, and another can possess the air-out function.

When the cigarette maker construction 10 is in use, when the temperature of the air inside the cigarette maker assembly 100 is below a predetermined level, indicating that a fire has not occurred inside the cigarette maker assembly 100, the switch assembly is deformed and opens the air opening, and smoke can enter or exit along the air opening. When the air temperature inside the cigarette machine assembly 100 is larger than the preset value, the cigarette machine assembly 100 is on fire, the deformation part of the switch assembly recovers to deform to close the air opening, the air entering the cigarette machine assembly 100 is cut off, the automatic fire extinguishing is achieved, and the fire extinguishing reliability is high.
