TILT SENSOR FOR CLEANING DEVICE
First Claim
Patent Images
1. A tilt sensor for interrupting operation of a vacuum, the sensor comprising:
- a housing securable relative to the vacuum, the housing having a pair of chambers defined therein;
an optical sensor located to define a detection zone within each of the chambers in which variations in light are detected;
an element located in the detection zone of each of the chambers and moveable in response to tilting of the vacuum;
whereby the tilt sensor is adapted to interrupt operation of the vacuum in response to the movement of the element.

Abstract
A tilt sensor for a cleaning device makes use of an optical sensor to interrupt operation of the device. In one implementation, the tilt sensor shuts off a UV light included in the cleaning device'"'"'s operations. The tilt sensor includes a housing with at least one chamber defined therein. A sliding or moving element is located in the chamber. The optical sensor is operatively associated with the chamber so that, in response to certain movement of the element within the chamber, the optical sensor signals the tilt sensor to turn off the UV light.

7. A tilt sensor for disrupting an electric circuit of a cleaning device, the tilt sensor comprising:
-
at least one wall defining at least one chamber therein; a photo-emitter and a photo-collector operatively associated with the chamber and the electric circuit; an element disposed in the chamber, the element configured to move relative to the photo-emitter in response to predetermined changes in angle relative to horizontal; wherein predetermined movement of the element relative to light from said photo-emitter causes said tilt sensor to disrupt the electric circuit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A cleaning device comprising:
-
a UV light source for disinfecting a cleaning medium; a housing operatively associated with at least one photo-emitter opposite at least one light receiver; at least one sliding element adapted to obstruct light emitted from said photo-emitter; at least one chamber adapted to prevent said sliding element from obstructing light emitted from said photo-emitter in response to changes in angle relative to horizontal of said housing; wherein light received by said photo-collector controls said UV light source. - View Dependent Claims (16, 17, 18)
