According to a first aspect there is disclosed a housing assembly comprising: a housing body defining an interior space configured to receive a switch, and an aperture configured to provide access to the interior space from an exterior of the housing body; a soft sealing element disposed in the aperture and bonded to the housing body so as to seal the aperture between the interior space and the exterior of the housing body, the soft sealing element configured to be elastically deformable to actuate the switch when disposed in the housing body; and a hard island fixed to the soft sealing element, wherein the hard island is separate from, and moveable relative to, the housing body into the interior space so as to elastically deform the soft sealing element to actuate the switch when disposed in the housing body.

A comb adjustment assembly for a beard trimmer includes a guide collar, a first adjusting connector, and an adjustor handle threadably coupled to the first adjusting connector. The first adjusting connector includes an extension arm, a connector coupled to the extension arm and configured to connect with an external structure. A guide collar aperture is formed in the guide collar, and the extension arm penetrates through the guide collar aperture. When the guide collar is in a fixed state, the adjustor handle is rotated, and the extension arm moves through the guide collar aperture. After the comb adjustment assembly is coupled to the beard trimmer in the present disclosure, the height of the comb unit may be regulated, and a user can adjust the hair cutting length by accurately regulating the extending length of the comb unit.

A hair clipper is provided, including a clipper housing defining a longitudinal housing axis, having a drive end and including a first housing half and a second housing half, each of the halves having a front end associated with the drive end and an opposite rear end, and each front end defining an attachment formation. Upon assembly of the clipper housing halves, the first and second housing halves are constructed so that the attachment formations are overlapping and are secured using fasteners inserted along a longitudinal axis parallel to the longitudinal housing axis.

A hair trimmer includes a trimmer housing having a drive end, a drive shaft projecting from the drive end, a chassis having one end associated with the drive shaft and an opposite end having at least one projecting charging pin, a radial flange at each of the ends, an endcap at each of the ends, each endcap having an axially extending annular skirt, the annular skirt dimensioned to enclose the corresponding chassis end, and a tubular sleeve of heat deformable plastic film dimensioned for slidingly surrounding the chassis and extending axially at least to the flanges, such that upon application of heat, the sleeve deforms around the chassis and the endcaps and forms a watertight enclosure.

A hair cutter includes a cutter head assembly and a main body. The cutter head assembly has a cutting type and is configured to be removably coupled to the main body. The cutter head assembly includes an identification part associated with the cutting type of the cutter head assembly. The main body includes a detection assembly, a drive assembly and a control board. The detection assembly is configured to transmit a signal indicative of the cutting type based on the identification part. The drive assembly is disposed inside the main body and includes an output shaft configured to be detachable from the cutter head assembly. The control board is disposed inside the main body and is in communication with the drive assembly and the detection assembly. The control board is configured to drive the cutter head assembly based on the cutting type of the cutter head assembly.

Disclosed in the present disclosure is a cutter head structure capable of achieving parallel movement. The cutter head structure includes a movable cutter assembly, a fixed cutter assembly, rolling members, a pressing member, and a gasket, where the movable cutter assembly is sliding fit with the fixed cutter assembly; the pressing member is provided with a first mounting position and second mounting positions, at least part of the movable cutter assembly is disposed at the first mounting position, and at least part of each of the rolling members is disposed at the second mounting position; and the gasket is disposed on one side of the fixed cutter assembly close to the movable cutter assembly. According to the present disclosure, the contact area between a tail portion of the movable cutter assembly and a tail portion of the fixed cutter assembly can be reduced, thereby reducing friction between the two assemblies.

The present disclosure provides an electric shaver, including a handle, and a driving device and a hair cutting unit; the driving device includes a motor housing, and a base, a mover component, a stator component, an elastic suspension component, and an elastic support that are disposed in the motor housing; the stator component is fixedly arranged on the base; an end of the elastic suspension component is fixedly connected to the base, and the other end is fixedly connected to the mover component; the base is suspended and connected to the motor housing through the elastic support; the stator component drives the mover component to move reciprocally in a predetermined direction; the mover component is connected to the hair cutting unit; the handle includes a bracket body and a vibration damping device; the vibration damping device includes a vibration damping oscillator and a cushioning mechanism.

According to a first aspect there is disclosed a housing assembly comprising: a housing body defining an interior space configured to receive a switch, and an aperture configured to provide access to the interior space from an exterior of the housing body; a soft sealing element disposed in the aperture and bonded to the housing body so as to seal the aperture between the interior space and the exterior of the housing body, the soft sealing element configured to be elastically deformable to actuate the switch when disposed in the housing body; and a hard island fixed to the soft sealing element, wherein the hard island is separate from, and moveable relative to, the housing body into the interior space so as to elastically deform the soft sealing element to actuate the switch when disposed in the housing body.

A lid is provided for a hair clipper having a housing containing a motor. The lid includes a first lid portion formed of a first material; and a second lid portion formed of a second material different from the first material and configured for covering the motor as the housing is assembled, and for dampening vibrations generated by the motor.
