A liquid dispensing unit for a hair removal device with a reservoir and an applicator in liquid communication with the reservoir. A first and second connector are in liquid communication with the reservoir. The first and second connector each have a respective first and second valve. A resilient tube is disposed between the connectors. The resilient tube has a neutral position with both valves closed and a second position with one valve open and one valve closed.

A shaving unit (16) is disclosed comprising a housing (12), a guard (20) stationary relative to the housing (12), a cutting edge (22) arranged at a distance from the guard (20) and stationary relative to the housing, a hair-entry opening bounded by the guard and the cutting edge, and a drum (24) arranged within the housing, the drum (24) being configured to be driven rotatingly about a longitudinal axis thereof. A plurality of counter cutting edges (28) is arranged on the drum (24), wherein the counter cutting edges (28) cooperate with the cutting edge (22) during rotation of the drum (24) about the longitudinal axis (26) for shearing or cutting hairs when the shaving unit (16) is moved over a skin (30). The shaving unit (16) further comprises a lubricating arrangement (36) with a liquid reservoir (38) filled with a lubricant and with a feed mechanism (41) for supplying the lubricant from the liquid reservoir (38) to at least one of the counter cutting edges (28) for providing a lubricating film (42) thereto. The feed mechanism (41) comprises a lubricating element (39) arranged adjacent to the drum (24) in a position such as to engage the at least one counter cutting edge (28) during rotation of the drum (24) about the longitudinal axis (26).

A razor cartridge comprises a housing, at least one first cutting member and at least one second cutting member. The at least one first cutting member and the at least one second cutting member are arranged in the housing. The at least one first cutting member is configured to shave in a first direction, and the at least one second cutting member is configured to shave in a second direction opposite to the first direction. A longitudinal support bar is arranged between the at least one first cutting member and the at least one second cutting member. The at least one first cutting member comprises a blade support including a top portion having an inner surface that, in use, faces away from a shaving plane and a blade attached to the inner surface of the top portion, wherein the blade includes a cutting edge.

In certain embodiments, a personal care device can include a housing, a functional assembly attached to the housing, a motor disposed within the housing and operatively connected to the functional assembly to move one or more components of the functional assembly, and a switch configured to move between at least two states.

A shaving applicator device provided with a shaving lubricant dispenser and an applicator head for applying lubricant directly on skin without hand touching the lubricant. The applicator head consists of a flow channel shaft, a roller having two end wheels and a rubber sleeve having self-closing slits. Under a pumping pressure, the lubricant emerges from the slits to spread on the roller surface. Gliding the roller on skin surface can spread the lubricant on the skin evenly with predetermined thickness. The dispenser may contain shaving foam, gel or liquid. For shaving liquid, foaming meshes are installed in the flow channel shaft for generating foam. Additionally, a combination shaver including a shaving lubricant dispenser, an applicator head and a razor unit is provided. In the combination shaver the razor unit and the applicator head are positioned in parallel back to back with a clearance.

A system and a method for adaptively releasing a lubricant or a cosmetic for a razor cartridge, a sensing unit detects a property of at least one of skin, air, water and a chemical agent in a region adjacent to the razor cartridge. A smart polymer provided on the razor cartridge is selectively responsive to a characteristic external stimulus by undergoing a physical or chemical change. A processing unit controls the release of the lubricant or the cosmetic by providing the characteristic external stimulus to cause the smart polymer to undergo a change. The processing unit compares the detected property to a reference threshold parameter and determines whether to provide the characteristic external stimulus to the smart polymer based on the comparison, thereby generating the lubricant or the cosmetic. The determined level of depletion of the smart polymer is indicated by a light, aural, or haptic indication.
