A shaver head assembly includes a shaver screen provided with outer fixed blades along an edge, an annular wall, and a blade holder that are coaxially provided. An outer peripheral entry groove is formed between adjacent outer fixed blades. The blade holder has outer movable blades. The outer movable blades and the outer fixed blades cooperate to cut the hairs. An annular collecting groove is formed between the edges of the shaver screen and the annular wall at an end approaching skins. The shaver head assembly further includes guide comb teeth provided on a periphery of the annular wall; the guide comb teeth extend substantially along an axial direction of the shaver screen. Each guide comb tooth has a tooth body for combing and shunting the hairs; a shunt channel is formed between adjacent guide comb teeth.

The invention relates to a shaver, comprising a handle, at least two rotary shaving heads, driven by at least one drive shaft which protrudes from said handle, and a support structure for supporting said shaving heads onto the handle so as to have their joined shaving surface (S) extend substantially perpendicular to said at least one drive shaft. The support structure is configured such, that a space (A), restricted at one side by the shaving heads and at the opposite side by the handle, is substantially open to its remaining, surrounding side.

A shaving head includes at least one cutting unit in which an external cutting member is subjected to a shaving action. The external cutting member is suspended relative to a holder of the shaving head through suspension means. The suspension means includes at least two pivot constructions, wherein one pivot construction enables a member of the suspension means to be pivotable relative to the holder. The other pivot construction enables the external cutting member to be pivotable relative to the suspension member. Furthermore, a pivoting stiffness of a connection of the latter pivot construction is lower than a pivoting stiffness of the first pivot construction. In this manner, good contour following performance is obtained at two levels, in both relatively small and relatively large curvature changing areas.

A shaver, a shaver cutting mesh, and a process for manufacturing the shaver cutting mesh. The process for manufacturing the shaver cutting mesh does not adopt an integral drawing process, but divides the cutting mesh into two parts to be machined, and then completely combines the two parts together by adopting a welding process, so that the mesh surface part is good in uniformity, the radian of the whole mesh surface also can be ensured, the comfort degree and the cleanness in shaving are further improved, and the housing part is machined at a larger thickness (such as 0.5 mm) than that of the mesh surface part to ensure the strength of a whole mesh cover.

A rotary electric shaver includes an outer blade whose upper surface functions as annular shaving surfaces having multiple hair inlets formed therein, and an inner blade that has a small blade which rotates while coming into sliding contact with a lower surface of the outer blade. The small blade is formed so that an inner blade base plate is partially erected, and is disposed in at least two rows on a circumference close to an outer periphery and on a circumference close to an inner periphery. There is provided a movable inner blade that has a movable small blade which is vertically movable along a front end surface in a rotation direction of the small blade, with respect to the predetermined small blade.

A shaver with a handle and at least two rotary shaving heads. The shaver driven by at least one drive shaft which protrudes from the handle, and a support structure for supporting the shaving heads onto the handle so as to have their joined shaving surface extend substantially perpendicular to the at least one drive shaft. The support structure is configured such that a space (A), restricted at one side by the shaving head and at the opposite side by the handle, is substantially open to its remaining, surrounding side.

In an external cutting member (10) which is configured to be used in a hair-cutting unit in combination with a rotatable internal cutting member, a base (11) includes at least one hair-cutting track (21) which is provided with a plurality of hair-entry openings, and an annular base portion (31) located between a central portion (17) of the base (11) and an innermost one of the at least one hair-cutting track (21). The annular base portion (31) is provided with a profiled section which is located between a straight inner section (32) and a straight outer section (33) of the annular base portion (31), which is annular about a central axis (16) of the external cutting member (10), and which is shaped according to a predefined profile, seen in a cross-section of the external cutting member (10) comprising the central axis (16).

According to an aspect, there is provided an electric shaver (100, 300a-b, 100 400, 500a-c) that comprises a first hair-cutting unit (150) that comprises: a first internal cutting member (252); and a first external cutting member (152, 152a, 152b, 152c) arranged to cover the first internal cutting member (252) and wherein the first internal cutting member (252) is movable relative to the first external cutting member (152, 152a, 152b, 152c); wherein the first external cutting member (152, 152a, 152b, 152c) comprises a first skin-contacting area comprising a first plurality of hair-entry openings (266), wherein the first skin-contacting area is arranged, in use, to contact skin. The electric shaver (100, 300a-b, 400, 500a-c) further comprises a second skin-contacting area arranged, in use, to contact the skin and a bi-polar radio frequency (RF) generator unit (120) configured to apply a first polarity RF voltage to the first external cutting member (152, 152a,152b, 152c), and wherein the entirety of the first external cutting member (152, 152a, 152b, 152c) is configured to conduct the first polarity RF voltage; and wherein the bi-polar RF generator unit (120) is further configured to apply a second polarity RF voltage to the second skin-contacting area.

A hair-cutting unit with rotatable cutting elements for use in a shaving device has hair entry slits of which at least a side surface facing in a direction generally opposite to a direction of rotation of the cutting elements, has a relatively flat and oblique intermediate segment between an upper segment forming a curved transition to the outer surface of the annular wall and a lower segment which serves for catching hairs and urging these into an upright position for achieving a close shave. Within a relatively broad range of shaving pressures, the pleat of skin bulging into a hair-cutting slit contacts a portion or at most all of the intermediate segment. Because the intermediate segment is relatively flat, changes in the extent of skin penetration in response to changes in shaving pressure are significantly reduced.

A shaver, a shaver cutting mesh, and a process for manufacturing the shaver cutting mesh. The process for manufacturing the shaver cutting mesh does not adopt an integral drawing process, but divides the cutting mesh into two parts to be machined, and then completely combines the two parts together by adopting a welding process, so that the mesh surface part is good in uniformity, the radian of the whole mesh surface also can be ensured, the comfort degree and the cleanness in shaving are further improved, and the housing part is machined at a larger thickness (such as 0.5 mm) than that of the mesh surface part to ensure the strength of a whole mesh cover.
