Removable assembly for a diffusing apparatus, and diffusing apparatus

A removable assembly (50;

• 250;
• 350;
• 450) for a diffusing apparatus (10;
• 710;
• 810;
• 910;
• 1910;
• 2010), the diffusing apparatus for dispersing into the air in the vapor state a substance in the liquid or solid state at ambient temperature, the removable assembly comprising:
• a storage container (60;
• 260;
• 360;
• 460) for containing the substance and including a drain orifice (61;
• 261;
• 361;
• 461), the drain orifice (61;
• 261;
• 361;
• 461) being oriented downwards when the removable assembly (50;
• 250;
• 350;
• 450) is in a position of use;
• and
• a dispensing member positioned at the outlet of the drain orifice (61;
• 261;
• 361;
• 461) and connected to the drain orifice, the dispensing member including a porous body (70;
• 270;
• 370;
• 470) having an evaporation surface situated at the exterior of the storage container (60;
• 260;
• 360;
• 460) to evaporate the substance into the surrounding air,
• wherein the storage container (60;
• 260;
• 360;
• 460) has a concave exterior shape surrounding at least partially a central free space (62;
• 262;
• 362;
• 462) so as to uncover a contact surface on the porous body (70;
• 270;
• 370;
• 470) on the side opposite the evaporation surface, the contact surface being accessible via the central free space (62;
• 262;
• 362;
• 462), and
• wherein the porous body (70;
• 270;
• 370;
• 470) includes a void (75;
• 275;
• 375;
• 475) situated in line with the central free space surrounded by the storage container, and the contact surface includes an interior surface of the void (75;
• 275;
• 375;
• 475).
