ROTARY ELECTRIC SHAVER
A rotary electric shaver includes an outer blade whose upper surface functions as annular shaving surfaces and 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 from below the annular shaving surfaces and. At least a portion of the multiple hair inlets is formed in an elongated hole shape extending along a radial direction of the annular shaving surfaces and, and an end portion (alternatively, both end portions and) in the radial direction has a widened portion (alternatively, and) which is open wider in a circumferential direction than a central portion.
1 . A rotary electric shaver comprising:
an outer blade whose upper surface functions as annular shaving surfaces and 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 from below the annular shaving surfaces and,
wherein at least a portion of the multiple hair inlets is formed in an elongated hole shape extending along a radial direction of the annular shaving surfaces and, and both end portions and or one end portion in the radial direction has a widened portion which is open wider in a circumferential direction than a central portion.
2 . The rotary electric shaver according to claim 1 ,
wherein the widened portion is formed from an upper surface across a side surface of the outer blade.
3 . The rotary electric shaver according to claim 2 ,
wherein the widened portion is formed so that an opening width thereof in the circumferential direction gradually becomes wider as a shape on the upper surface of the outer blade goes from the central portion to the end portion in the radial direction.
4 . The rotary electric shaver according to claim 1 ,
wherein the widened portion is formed on a side surface of the outer blade.
5 . The rotary electric shaver according to claim 1 ,
wherein the widened portion is formed on the upper surface of the outer blade.
6 . The rotary electric shaver according to claim 1 ,
wherein the elongated hole-shaped hair inlet is formed in a shape whose long side portion is linear, or in a shape whose long side portion is entirely or partially curved.
7 . The rotary electric shaver according to claim 2 ,
wherein the elongated hole-shaped hair inlet is formed in a shape whose long side portion is linear, or in a shape whose long side portion is entirely or partially curved.
8 . The rotary electric shaver according to claim 3 ,
wherein the elongated hole-shaped hair inlet is formed in a shape whose long side portion is linear, or in a shape whose long side portion is entirely or partially curved.
9 . The rotary electric shaver according to claim 4 ,
wherein the elongated hole-shaped hair inlet is formed in a shape whose long side portion is linear, or in a shape whose long side portion is entirely or partially curved.
10 . The rotary electric shaver according to claim 5 ,
wherein the elongated hole-shaped hair inlet is formed in a shape whose long side portion is linear, or in a shape whose long side portion is entirely or partially curved.
