The corresponding relation between the resistance value of the resistor, the voltage/current at two ends and the wavelength of the optical filter is preset.

The resistor 502 is disposed on the circuit board 501 and electrically connected to the control circuit board 9 inside the beauty instrument via the electrode assembly 51. The electrode assembly 51 includes a set of

counter electrodes

511 and 512, which are electrically connected to two ends of the resistor 502 on the circuit board 501 of the filter assembly, respectively, for detecting the voltage at the two ends of the resistor 502, and identifying the resistor 502 and the corresponding filter according to a predetermined value, so as to obtain the wavelength of the used filter. A pair of

electrodes

511 and 512 of the electrode assembly 51 are fixed by an insulating body 513 (see fig. 10 a), and one end of each electrode is electrically connected to one end of the resistor 502 on the filter assembly circuit board 501, and the other end is electrically connected to the control circuit board 9 in the beauty instrument.

electrodes

511 and 512 of the electrode assembly 5 inside the beauty instrument is respectively connected with one end of the resistor 502 on the circuit board 501, so that the control circuit board 9 in the beauty instrument detects the resistance value or the voltage value or the current value of the resistor through the circuit, and inquires the filter wavelength corresponding to the resistance value or the voltage value or the current value so as to identify the different filter assemblies 5.

Further, an elastic relief groove 505 may be formed at an inner side of the bracket 50 and at a side of the reverse-buckled elastic leg 504 to increase elasticity of the reverse-buckled elastic leg 504 from one side and to provide a space for a position where the reverse-buckled elastic leg 504 is deformed. Further, an elastic relief groove 503 is formed at the inner side of the bracket 50 and at the other side of the reverse-buckled elastic edge 504, increasing the elasticity of the reverse-buckled elastic edge 504 from the other side and providing a space for the deformation of the reverse-buckled elastic edge 504. Elastic yielding grooves are formed on two sides of the inverted elastic edge 504, so that the elasticity of the inverted elastic edge 504 and the position space of elastic deformation towards the two sides are increased. An elastic yielding groove can be formed on one side of the inverted elastic edge 504, or a yielding groove is formed on the inner wall of the clamping groove 52, so that an elastic contact point or an anti-cracking buffer structure is formed between the inner wall of the clamping groove and the edge surface of the optical filter.

Referring to fig. 7, since the inner side of the bracket 50 forms an anti-cracking buffer structure, in order to facilitate assembling the optical filter (filter glass) 500 in the bracket 50, the bracket 50 is configured as an assembly structure or a movable assembly structure, so as to respectively splice and clamp the optical filter 500 by a plurality of frames of the bracket; alternatively, the holder 50 may be an open structure, and when the filter (filter glass) 500 is mounted, the open side of the holder may be rotated and closed to clamp and fix the periphery of the filter (filter glass) 500.

The circuit board 501 is preferably located on the surface of the holder fixing position, such as the back of the holder fixing position, so as to connect the electrode assembly 51, the electrode assembly 51 is installed inside the working head 100, and the two

electrodes

511 and 512 are electrically connected to the two ends of the resistor 502 on the circuit board 501, respectively, and may be in contact type electrical connection or in spring type abutting connection. The surface on the other side of the bracket fixing portion 506, for example, the front surface of the bracket fixing portion, is formed with a snap-fit portion, for example, a slot 507, and may also be formed with a hook or a snap or a protrusion, so as to form a snap-fit with the inside of the working head.

The filter assembly 5 is installed in the light-emitting working head 100 and located in front of the light source assembly 3 to filter the emergent light generated by the light source assembly 3. Specifically, a bin 8 is arranged in the light-emitting working head part 100, a bin opening 82 for the light filtering component 5 to enter or exit the bin 8 is formed in the shell, the bin opening 82 is communicated with the bin 8, the light filtering component 5 is inserted into the beauty instrument from the bin opening 82 on the shell, accommodated and clamped in the bin 8, or ejected from the bin 8 and extended out from the bin opening 82.
