An optical hair removal device as claimed in claim 6, wherein: the cleaning plate (611) further comprises an iron plate body (6112) which is integrally formed with the cleaning part (6111); the locking assembly comprises a first electromagnet (82) arranged on the side face, far away from the spring (612), of the second extension shell (61) and a second electromagnet (83) arranged on the side face, on the same side as the spring (612), of the second extension shell (61), and the first electromagnet (82) and the second electromagnet (83) are electrically connected with a controller (8) for controlling the power-on state and the power-off state of the first electromagnet and the second electromagnet.

8. An optical hair removal device as claimed in claim 7, wherein: the controller (8) is electrically connected with a control switch (111) for controlling the emitter (21) to emit light, and the controller (8) is also electrically connected with the emitter (21); an infrared temperature sensor (85) for detecting whether the depilating instrument is close to the skin is arranged in the locking shell (5), the temperature sensor is electrically connected with the controller (8), and a reasonable temperature range of the skin of the human body (2) is preset in the controller (8); when the temperature detected by the infrared temperature sensor (85) is not in a reasonable temperature interval and the control switch (111) is pressed, the controller (8) controls the emitter (21) not to be started.
