AI Technical Summary
While existing electric hair trimmers offer the option of detachable and replaceable blades, they struggle to balance the reliability, durability, and cost of the light source's sealing, leading to frequent light source replacements or increased design complexity.
The light source is placed inside the handle, and the light guide is integrated into the detachable blade head. The output optical axis of the light source is parallel to the output axis of the motor, and the light-emitting surface of the light guide faces the working area, realizing automatic alignment of the optical path and simplifying the power supply design.
It achieves reliable sealing and long-term protection of the light source, reduces the cost of replacing the cutter head, ensures efficient and stable optical transmission, balances functional integration and ease of use, and improves the lifespan of the light source and the user experience.

Abstract
Claims
1. An electric hair trimmer with a lighting system, characterized in that it includes: The handle (1) has a motor (12) installed in the motor mount (11) at its output end; The blade head (2) can be quickly attached and detached from the motor mount (11) of the handle (1); The lighting system (3) is located on the handle (1) and the blade head (2); The lighting system (3) includes: The light source (31) is placed inside the motor base (11), and its output optical axis is basically parallel to the output axis of the motor (12); A light guide (32) is placed on the head of the cutter (2), with its light-receiving surface (321) corresponding to the output optical axis of the light source (31) and its light-emitting surface (322) facing the working area of the head of the cutter (2).
2. The electric hair trimmer as described in claim 1, characterized in that: The light guide (32) extends upward from the light-receiving surface (321) to the light-emitting surface (322) along the inner side of the front of the outer wall (22) of the blade head (2).
3. The electric hair trimmer as described in claim 2, characterized in that: The lens (33) of the lighting system (3) is installed inside the motor mount (11) and located above the light source (31). The top surface of the lens (33) is basically parallel to the top surface of the motor mount (11). The light emitted by the light source (31) is focused by the lens (33) and transmitted upward to the light-receiving surface (321) of the light guide (32).
4. The electric hair trimmer as described in claim 3, characterized in that: The output optical axis of the light source (31) passes through the middle of the light-receiving surface (321) of the light guide (32), and the light-receiving surface (321) is symmetrically distributed relative to the output optical axis to improve the efficiency of the light source (31) in transmitting light to the light guide (32).
5. The electric hair trimmer as described in claim 4, characterized in that: The light-emitting surface (322) of the light guide (32) extends laterally along the outer wall (22) of the blade head (2), which can increase the irradiation width.
6. The electric hair trimmer as described in claim 5, characterized in that: The output shaft (121) of the motor (12) extends from the motor base (11), and its top end is much higher than the top surface of the motor base (11), so that the driving force of the motor (12) can be output upward to the input end (21) of the cutter head (2).
7. The electric hair trimmer as described in claim 6, characterized in that: The top surface of the motor mount (11) is substantially perpendicular to the output axis of the motor (12); The angle between the top surface of the upper edge of the peripheral wall (111) and the top surface of the lower edge of the outer wall (22) of the motor base (11) and the top surface of the motor base (11) is within the range of 10°-25°, which is used to increase the convenience of mounting and dismounting the cutter head (2) on the motor base (11) of the handle part (1).
8. The electric hair trimmer as described in claim 7, characterized in that: The blade head (2) is a shaving head (2a), and the upper light-emitting surface (3221a) of the shaving light guide (32a) and the top surface of the outer wall (22a) are on the same plane.
9. The electric hair trimmer as described in claim 7, characterized in that: The blade head (2) is a trimmer blade head (2b); The upper middle part of the front side of the outer wall (22b) of the trimmer head (2b) is recessed inward into a U-shaped structure, and the opening of the U-shaped structure faces upward to correspond to the trimmer blade.
