Abstract
Among other things, techniques are described for self-cleaning door handles. A door handle for a vehicle includes a housing including a hand grip; a hygienic film that is formed around a portion of a circumference of the hand grip; a plurality of cylindrical rollers rotatably connected to the housing and are configured to rotationally guide the hygienic film along the portion of the circumference of the hand grip; and a light that is configured to emit electromagnetic radiation in an ultraviolent spectrum and configured to irradiate at least one portion of the hygienic film to reduce a quantity of bacteria on the at least one portion of the hygienic film.
Claims20
A door handle for a vehicle, the door handle comprising:
- a housing including a hand grip;
- a hygienic film that is formed around a portion of a circumference of the hand grip;
- a plurality of cylindrical rollers rotatably connected to the housing and configured to rotationally guide the hygienic film in a circumferential path around a longitudinal axis of the hand grip along the portion of the circumference of the hand grip such that the hygienic film rotates around the longitudinal axis of the hand grip in the circumferential path;
- and
- a light that is configured to emit electromagnetic radiation in an ultraviolet spectrum and configured to irradiate at least one portion of the hygienic film to reduce a quantity of bacteria on the at least one portion of the hygienic film.
A method comprising:
- advancing, by a plurality of cylindrical rollers, a hygienic film in a circumferential path around a longitudinal axis of a hand grip of a door handle for a vehicle and around a portion of a circumference of the hand grip of the door handle for the vehicle such that the hygienic film circumferentially rotates around the longitudinal axis of the hand grip in the circumferential path;
- and
- irradiating, by a light mounted within the door handle, a contaminated portion of the hygienic film using electromagnetic radiation in an ultraviolent spectrum to reduce a quantity of bacteria on the contaminated portion of the hygienic film.
A non-transitory computer-readable storage medium comprising at least one program for execution by at least one processor of a first device, the at least one program including instructions which, when executed by the at least one processor, cause the first device to perform operations comprising:
- advancing, by a plurality of cylindrical rollers, a hygienic film in a circumferential path around a longitudinal axis of a hand grip of a door handle for a vehicle and around a portion of a circumference of the hand grip of the door handle for the vehicle such that the hygienic film circumferentially rotates around the longitudinal axis of the hand grip in the circumferential path;
- and
- irradiating, by a light mounted within the door handle, a contaminated portion of the hygienic film using electromagnetic radiation in an ultraviolent spectrum to reduce a quantity of bacteria on the contaminated portion of the hygienic film.
