[0036] Connecting part 6, one part is connected in the end of fixed frame 3 outside second filter 4, another part of connecting part 6 is connected with sliding piece 5 through the wall outside sliding guide 22

[0037] When the first filter 8 and the second filter 4 exist simultaneously in the light emitting direction of the light source 7, the light emitted by the light source 7 passes through the two filters, and the energy of the light emitted by the light source 7 is reduced, at which time the light emitted by the light emitting head 1 of the hair removal instrument can be used for warm hair removal; when it is necessary to increase the energy of the light emitted by the light source 7, the sliding member 5 can be manually pulled to slide to the other end of the sliding guide rail 22, and the fixed frame 3 is pulled by the sliding member 5 through the connection of the connecting part 6 and the fixed frame 3 during the sliding process, so that the fixed frame 3 slides into the sliding space 21 on the side close to the sliding guide rail 22, and the second filter 4 moves away from the outside of the first filter 8 along with the sliding of the fixed frame 3, at which time only the first filter 8 exists in the light emitting direction of the light source 7, and the light emitted by the light source 7 only passes through the first filter 8, so that the energy of the light emitted by the light source 7 is increased, at which time the light emitted by the light emitting head 1 of the hair removal instrument can be used for hair removal; if it is necessary to adjust to the state that the first filter 8 and the second filter 4 exist simultaneously in the light emitting direction of the light source 7, the sliding member 5 can be moved back to the original position by manual pulling, and the connecting part 6 pushes the fixed frame 3 to slide into the sliding space 21 on the side away from the sliding guide rail 22 during the process, so that the second filter 4 moves back to the outside of the first filter 8 along with the sliding of the fixed frame 3 and overlaps with the first filter 8 in the light emitting direction of the light source 7.

[0038] The filter changing structure adjusts the number of filters in the light emitting direction of the light source 7 by moving the second filter 4 out of or into the position outside the first filter 8, so as to change the energy of the light emitted by the light emitting head 1 during light emission, so that the light emitting head 1 of the hair removal instrument can meet different hair removal use requirements, and the operation is convenient, the structure is simple, and the production cost is reduced.

[0039] It needs to be further explained that, as Figure 4 and Figure 9 shown, the end of the fixed frame 3 on the side close to the sliding guide rail 22 is provided with a first matching opening 31, the wall surface of the fixed frame 3 outside the two sides of the first matching opening 31 is provided with a first groove body 32, the second filter 4 is inserted into the first matching opening 31 along the direction that the two sides thereof match with the first groove body 32, so as to be connected with the fixed frame 3, and the connecting part 6 is connected to the part of the fixed frame 3 outside the first matching opening 31.
