The handle has a first attachment member positioned at least partially within the receptacle and arranged to detachably engage the head when the at least a portion of the head is inserted into the receptacle and a second attachment member positioned at least partially within the receptacle and arranged to engage the head when the at least a portion of the head is inserted into the receptacle. The second attachment member is a different type of attachment member than the first attachment member. In a particular embodiment, the hair grooming appliance is a shaver.

In a hair-cutting unit (6) of a shaving unit (3), a supporting member (30) surrounding and supporting an external cutting member (10) is present, and further a holder (40) mounted to the supporting member (30) is present. A base portion (7) of the shaving unit (3) comprises a hair-collecting chamber (50), a drive shaft (60) extending through an opening (71) in a bottom portion (70) of the base portion (7), and a first shielding member (72) surrounding this bottom opening (71). The holder (40) comprises a second shielding member (42) surrounding an opening (41) in the holder (40), wherein, in a coupled condition of the hair-cutting unit (6) and the base portion (7), the first shielding member (72) and the second shielding member (42) together surround the drive shaft (60) and thereby seal the bottom opening (71) relative to the hair-collecting chamber (50).

A shaving device comprises a head structure (2) and a base structure (4). The head structure (2) is configured to retain and support at least one shaving head (30A, 30B, 30C). The head structure (2) is releasably retainable on the base structure (4). The base structure (4) is free of support elements in an area of an outer circumference of the head structure (2) such that the head structure (2), when coupled to the base structure (4), is not supported in the area of its outer circumference. The head structure (2), when coupled to the base structure (4), is substantially only retained on the base structure (4) by a retaining force provided by a retaining structure of the base structure (4). When an overloading force is exerted on the head structure (2), the force is transferred to a coupling element (8) arranged in a central area (2A) of the head structure (2) such that the coupling element (8) is released from the retaining structure of the base structure (4) in order to prevent damage to the head structure (2).

A detachable floating shaver includes a head, a casing having a third through hole, a main housing, a first floating member, and a second floating member. Through the connection and positioning relationship between the two parent and child pivot portions, that is, the first floating member and the second floating member, the head can achieve a cross rotation relative to the main housing. The second floating member has a connecting member; through the detachable connection between the second floating member and the connecting member, the head of the shaver is detachably connected, which is convenient for replacement, cleaning and maintenance and is more practical. The shaver can achieve 360 rotation through two parent and child pivot portions and two elastic sleeves, and the effect of floating contact of the shaver with the user's face is good.
