Removable assembly for a diffusing apparatus

A removable assembly for a diffusing apparatus (1), the diffusing apparatus (1) comprising a substance to be diffused in a vapor state into surrounding air, the removable assembly comprising:

• a storage container (10), said storage container (10, 110, 210) including an orifice (12), said storage container (10, 110, 210) containing said substance;
• said substance including at least one substance selected from semiochemical molecules, pheromones, allomones, kairomones, synomones and fragrances of natural or synthetic origin;
• a distributor member (30, 130) positioned at an outlet of said orifice (12) and connected to said orifice (12) to evaporate the substance into the surrounding air;
• said distributor member (30, 130) including a porous body (30, 130) having an evaporation surface (39) situated outside said storage container (10, 110, 210);
• wherein the orifice of the container connected to the distributor member is oriented downward in a direction of acceleration due to gravity when the diffusing apparatus is in a position of use;
• wherein said substance has a viscosity varying as a function of temperature, said viscosity and a surface tension of the substance being such that when the acceleration due to gravity is exerted from the orifice (12) in the direction of the porous body (30, 130) in such a manner as to constitute a motive force susceptible of generating a flow from the storage container towards said evaporation surface (39), said substance does not flow through said porous body (30, 130) at an ambient temperature below a first temperature, the first temperature being greater than 0° C., and said substance flows through said porous body (30, 130) at a second temperature higher than said first temperature;
• and
• wherein said removable assembly includes an air flow guide (41) situated at a periphery of said orifice (12), said air flow guide (41) configured to guide a flow of air in a direction tangential to the evaporation surface (39), in which said removable assembly includes sealing elements for producing sealed connections between the storage container (10) and said air flow guide (41) and between the air flow guide (41) and said porous body (30, 130).
