The invention provides a disinfection device (5) for disinfecting a
personal care device (3) with disinfection light. The disinfection device comprises a housing (17) in which a light module (23) is arranged, the light module (23) having a
light source (25), a first main side (27) emitting disinfection light generated by the
light source, and a second main side (29) opposite the first main side. The housing (17) also accommodates a receiving chamber (49) arranged at the first main side of the light module to hold at least part of the
personal care device in the disinfection position and an
air chamber (51) arranged at the second main side of the light module. At least one first
air channel (59a, 59b) connects the receiving space to the
air chamber and at least one second
air channel (61) connects the
air chamber to the ambient space. Each first
air channel is arranged exclusively outside the light module, and the disinfection device is configured to provide at least one third air channel (63) in a disinfection position of said part of the
personal care device, the third air channel (63) connecting the receiving chamber with the ambient space. During use, the
light source heats the air in the air chamber and the receiving chamber, thereby creating a natural convective air flow through the disinfection device to enable effective
drying of the portion of the personal care device in addition to the disinfection function.
