Electric shaver
View Patent ↗A height dimension D 1 of a head section 4 is smaller than a front-back dimension D 2 of the head section 4. The head section 4 has therein a linear actuator 12 as a drive source. Inner blades 13 are coupled to a drive coupling section protruding form an actuator main section. A height dimension of the actuator main section is smaller than a front-back dimension of the actuator main section.
1. An electric shaver, comprising:
a body section incorporating a power source, wherein the body section includes a support portion arranged at an upper end of the body section;
a head section pivotally supported by the support portion of the body section such that the head section is configured to pivot about a first axis, wherein the head section includes an upper end and a lower end;
a plurality of outer blades arranged in parallel with each other at the upper end of the head section in a first plane that is orthogonal to the first axis, wherein the plurality of outer blades protrude in a first direction from the upper end of the head section;
an actuator incorporated in the head section, wherein the actuator is electrically connected to the power source incorporated in the body section and includes an actuator main section, which includes an upper end and a lower end, and a drive coupling section, which protrudes in the first direction from the upper end of the actuator main section, wherein the actuator main section includes a stator and a movable element configured to reciprocate along a second direction relative to the stator, and the drive coupling section is coupled to and configured to be reciprocated by the movable element, wherein the second direction is orthogonal to the first plane; and
a plurality of inner blades supported by the drive coupling section of the actuator, the plurality of inner blades being coupled to the drive coupling section and configured to reciprocate along the second direction;
wherein a first maximum height from the upper end to the lower end of the head section is smaller than a first maximum width of the head section along a third direction that is orthogonal to both the first direction and the second direction,
wherein a second maximum height from the upper end to the lower end of the actuator main section is smaller than a second maximum width of the actuator main section along the third direction,
wherein the stator includes a plurality of tooth sections and a plurality of coils respectively wound about the plurality of tooth sections,
wherein the plurality of tooth sections have a common axis orthogonal to the longitudinal axis of the body section,
wherein the common axis is orthogonal to a longitudinal axis of the outer blades, and
wherein the movable element has a surface that faces an end face of each of the plurality of coils.
