  • Patent number: 11027441
    Abstract: A hair cutting device includes a hair cutting device body and an interchangeable comb unit for defining a hair length after cutting. The hair cutting device body further includes a comb interface for releasable attachment of the comb unit to the hair cutting device body, and a hair length indicator operatively coupled to the comb interface for indicating the hair length to a user. The interchangeable comb unit includes a comb identification member for identifying a hair length associated with the comb unit, and the comb interface includes a comb recognition arrangement being electrically coupled to the hair length indicator. The comb recognition arrangement is configured to sense the comb identification member when the comb unit is connected to the hair cutting device body, and to provide an electronic signal indicative of the hair length associated with the comb unit to the hair length indicator.

  • Patent number: 10029377
    Abstract: The present application relates to a hair trimming device (10). The hair trimming device has a body (11) with a cutting blade assembly (20). A cutting guide (40) is provided on the body and the position of the cutting guide is adjustable relative to the cutting blade assembly to provide a cutting distance from a user's skin to enable hair to be cut to a desired length. A locking unit (60) is also provided to lock the cutting guide at a desired position relative to the cutting blade assembly. The locking unit comprises a first locking element (64), a second locking element (65) and at least one receiving recess (83). The first and second locking elements are alternately locatable in the or one of the receiving recesses when the position of the cutting guide is adjusted relative to the cutting blade assembly to lock the cutting guide at different positions.
