A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.

An oral care refill head (300), the oral care refill head (300) may be detachably coupled to a handle (200). The handle (200) may include a stem (250) that is received within a connection cavity (326) of the oral care refill head (300). The stem (250) and the connection cavity (326) may have specific geometries and structures to ensure an adequate coupling therebetween. An oral care implement (100), the oral care implement (100) have a pressure sensing assembly, excessive pressure applied onto the oral care refill head (300) will cause the motor (140) and a motor chassis (401) to rock. As the motor chassis (401) rocks, a contact element (456) thereon will actuate a pressure actuator element (455). In response, a control unit (150) may initiate generation of a user perceptible signal to inform the user of the excess pressure.

A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.

A cleaning tool includes a holding rod and a cleaning assembly that is disposed on at least one end of the holding rod, wherein a connecting assembly is disposed between the holding rod and the cleaning assembly. The connecting assembly includes a controlling member having an engaging portion and a pressing portion. When the holding rod is connected to the cleaning assembly, the engaging portion corresponds to an engaged portion on an inner wall of a connecting tube of the cleaning assembly, so that the holding rod and the cleaning assembly are locked to each other, and the pressing portion is located out of the connecting tube. When the pressing portion is pressed, the engaging portion is disengaged from the engaged portion, thereby allowing the holding rod to be disengaged from the cleaning assembly.

A photosensitive pressure alarm device for electric cleaning care appliances comprises at least one light source, at least one photosensitive unit, a light reflecting surface, a detection circuit, and an alarm portion. The light source and the photosensitive unit are provided on a movable component or a movable component on a same side, and the light reflecting surface is provided on a stationary component or the movable component. Under the combined action of an external force (F.sub.1) and an elastic force (F.sub.2), the light reflecting surface or the light source and the photosensitive unit provided on the movable component can move with the movable component, and the incident angle and the reflection angle of the light on the light reflecting surface change, causing that the light receiving area of the photosensitive unit changes, and in turn resulting in change of the electrical performance of the photosensitive unit.

An apparatus, a system and a method for drying pets include a blower that directs a flow of air through two tubes to two mitts. The two mitts receive the flow of air from the blower and direct the flow of air through perforations to dry the pet. The air may flow through tapered channels within the mitts.

An oral care implement with a soft tissue cleaner. The oral care implement may include a handle and a head, the head having a first surface, and an opposite second surface, and a peripheral surface extending between the first and second surfaces. A soft tissue cleaner may have a first cleaner fixed to the second surface of the head and a second cleaner fixed to the peripheral surface of the head. Furthermore, the second cleaner may incorporate a plurality of grooves extending at least a portion of the distance from the first surface to the second surface along the peripheral surface.

A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.
