(66) The nose hair trimmer head 2b comprises a first trapezoidal cylindrical outer wall 22c. An upper end of the first trapezoidal cylindrical outer wall 22c of the nose hair trimmer head 2b is narrowed radially to form a second trapezoidal cylindrical outer wall 22cl. A bottom portion of the second trapezoidal cylindrical outer wall 22cl is connected to the upper end of the first trapezoidal cylindrical outer wall 22c of the nose hair trimmer head 2b to form an annular step surface 224. The light-emitting surface 322c of the trimming light guide body 32c and the annular step surface 224 of the nose hair trimmer head 2b are located on a same plane.

(67) In one embodiment, the light-receiving surface 321 of the trimming light guide body 32c is circular. A center of the light-receiving surface 321 of the trimming light guide body 32c is located on the output optical axis of the light source 31.

(68) The light-emitting surface 322c of the trimming light guide body 32c is in a kidney shape with a convex middle portion. A curvature of the light-emitting surface 322c of the trimming light guide body 32c is substantially consistent with a curvature of the annular step surface 224 of the nose hair trimmer head 2b.

(69) An upper portion of the trimming light guide body 32c, close to the light-emitting surface 322c of the trimming light guide body, defines a kidney-shaped positioning flange 323c with a contour similar to the light-emitting surface 322c. An upper end surface of the kidney-shaped positioning flange 323c is in contact with a lower surface of the annular step surface 224 of the nose hair trimmer head 2b.

(70) A light channel 225 is defined on a front side of the second trapezoidal cylindrical outer wall 22cl of the nose hair trimmer head 2b. The light channel 225 is inclined inward from the light-emitting surface 322c of the trimming light guide body 32c, and a top portion of the light channel 225 is open.

(71) The light emitted from the light source passes through the lens and enters the light-receiving surface 321c of the nose hair trimming light guide 32c that is circular. The light is then transmitted through the trimming light guide body 32c to the light-emitting surface 322c that is kidney-shaped. The light is then projected upward along the light channel 225 to a nose hair trimming area. The light-emitting surface 322c of the nose hair trimming light guide 32c that is kidney-shaped expands an illumination range, while the kidney-shaped positioning flange 323c ensures stability of the light path.

(72) The illumination system of the present disclosure comprises the light source, the lens, and the light guide body, and the output optical axis of the light source is parallel to the output shaft of the motor, which achieves effective illumination of the working area of the electric hair trimmer.

(73) The foregoing descriptions are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement, or improvement within the technical scope of the present disclosure should be included in the protection scope of the present disclosure.
