Abstract: A cutter head (10) for a hair cutting machine, having an upper blade (14) and a lower blade (12) that is adjustable relative to the upper blade using an actuating element (100), having a support (32) with an adjusting element (16) which is adjustable relative to the support using the actuating element (100) and which carries out a relative movement between the upper blade and the lower blade in the direction of cutting. The actuating element can be selectively placed in one of two opposite side areas of the support for actuating the adjusting element connected to the lower blade (12). The actuating element (100) is removably connected to a shaft (62), mounted in the support (32), having a first element. The adjusting element is a second element having, in the cross-section, a U- and/or C-shape, the transverse or base limb being connected to the lower blade (12).

Abstract: The invention relates to a cutter head (10) for a hair cutting machine, having an upper blade and a lower blade (12) that can be adjusted with respect to the upper blade by means of an actuating element, comprising a support with an adjusting element which can be adjusted with regard to the support by means of the actuating element (100) and which carries out a relative movement between the upper blade and the lower blade in the direction of cutting. The actuating element can be selectively placed in one of two opposite side areas of the support for actuating the adjusting element that is connected to the lower blade (12). The actuating element (100) can be removably connected to a shaft (62) mounted in the support (32) or to a first element protruding therefrom. The adjusting element is a second element having, in the cross-section, a U and/or C-shape, the transverse or base limb being connected to the lower blade (12).

Abstract: Device (1) for drying hair, comprising a hand-held unit (2) which is adapted to emit or discharge a flow of air to be directed onto the hair, characterized in that the hand-held unit (2) has a power source (18) which is arranged in a path (13) of the air flow to be emitted or discharged from the unit (2). In this way, heat or thermal energy that is generated in the power source (18) can be recovered or retrieved and transferred directly to the air flow in the device (1) so as to collect or scavenge waste heat from the power source.
