Abstract
Provided is a brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent. The brush head comprises a bristle set for brushing the teeth and a nozzle for emitting the cleaning agent. When actuating the bristle set from a first configuration, which is optimized for brushing, to a second configuration, which is optimized for emitting of a cleaning agent, at least a part of the bristle 5 set is moved away from the nozzle and/or away from a path of the cleaning agent when being emitted from an orifice of the nozzle.
Claims19
A brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent, the brush head comprising:
- a platen with a first face,
- a first bristle set extending from the first face for brushing the teeth,
- a nozzle extending from the first face comprising an orifice for emitting the cleaning agent from the orifice towards a direction pointing away from the first face of the platen, and
- an actuator for moving at least a part of the first bristle set relative to a path of the cleaning agent from the orifice such that the brush head is configurable to adopt a first configuration in which the path is at least partially blocked by said at least part of the first bristle set, and a second configuration in which the path is cleared of said at least part of the first bristle set.
A brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent, the brush head comprising:
- a platen with a first face;
- a first bristle set extending from the first face for brushing the teeth;
- a nozzle comprising a temporarily extendable portion and an orifice for emitting the cleaning agent from the orifice towards a direction pointing away from the first face of the platen, wherein the orifice for emitting the cleaning agent is located at a tip of the temporarily extendable portion of the nozzle and the nozzle with the temporarily extendable portion is configured for extending its length when emitting the cleaning agent from the orifice of the nozzle;
- and
- an actuator for moving at least a part of the first bristle set relative to a path of the cleaning agent from the orifice such that the brush head is configurable to adopt a first configuration in which the path is at least partially blocked by said at least part of the first bristle set, and a second configuration in which the path is cleared of said at least part of the first bristle set, wherein the temporarily extendable portion of the nozzle is configured for actuating the first bristle set from the first configuration to the second configuration.
