DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The present invention will be described in more detail below with reference to the drawings and examples. It is understood that the specific examples described here are merely for the purpose of interpreting the present invention and do not limit the present invention. In addition, in order to facilitate the explanation, the drawings show only the parts related to the present invention and do not show the entire structure.

[0018] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, may be fixedly connected, may be detachably connected, may be integrated, may be mechanically connected, may be electrically connected, may be directly connected, may be indirectly connected via an intermediate medium, may be an internal communication between two elements, or may be an interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation.

[0019] In this invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include direct contact between the first feature and the second feature, or may include contact between the first feature and the second feature through another feature between them without direct contact. Furthermore, a first feature being "above," "above," and "on the upper surface" of a second feature may include directly above and diagonally above the second feature, or simply indicate that the horizontal height of the first feature is higher than that of the second feature. A first feature being "below," "below," and "on the lower surface" of a second feature may include directly below and diagonally below the second feature, or simply indicate that the horizontal height of the first feature is lower than that of the second feature.

[0020] In the description of the present embodiment, the orientations and positional relationships of the terms "upper", "lower", "right", etc. are based on the orientations and positional relationships shown in the drawings, and are merely for the purpose of facilitating the description and simplifying the operation, and do not indicate or imply that the described devices or elements must have a specific orientation, be configured and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are merely used for distinction in the description, and do not have any special meaning.

[0021] 1 to 8, an embodiment of the present invention provides a light output module including a light source 1, a first filter 2, a second filter 3 and a switching structure 4, the first filter 2 is fixedly disposed on the path of the light emitted by the light source 1, the second filter 3 has a first position and a second position, when in the first position, the second filter 3 is on the path of the light emitted by the light source 1, and the light emitted by the light source 1 passes through the first filter 2 and the second filter 3 in sequence, or passes through the second filter 3 and the first filter 2 in sequence to form a first care light, when in the second position, the second filter 3 is offset from the path of the light emitted by the light source 1, and the light emitted by the light source 1 passes through the first filter 2 to form a second care light. The switching structure 4 is connected to the second filter 3 and moves the second filter 3 to switch between the first position and the second position. It should be emphasized that there is an overlap between the wavelength range through which the second filter 3 allows light to pass and the wavelength range through which the first filter 2 allows light to pass, and therefore the light output module forms the first care light and the second care light respectively when the first filter 2 overlaps with the second filter 3 and when the first filter 2 does not overlap with the second filter 3. Of course, the function of the second care light when irradiated to the skin can cover the function of the first care light when irradiated to the skin, but the effect of the second care light when irradiated to the skin is different from that of the first care light.

[0022] In the above-mentioned light emitting module, by installing the first filter 2 and the movable second filter 3, the entire light emitting module can emit light of two different wavelength bands. When it is applied to a skin care device, there is no need to replace the head, and two different skin care functions can be realized, which saves the occupied space and avoids the risk of losing the head.

[0023] In one embodiment, the wavelength range through which the first filter 2 allows light to pass is between 530nm and 1200nm, and light within this range can achieve the functions of beauty and hair removal; the wavelength range through which the second filter 3 allows light to pass is between 500nm and 650nm, and light within this range simultaneously includes the absorption peak values ​​of melanin pigment and oxyhemoglobin, so it can be used for melanin pigment removal and acne scar treatment (belonging to the category of beauty); that is, when the second filter 3 is in the first position, the light output module performs the functions of melanin pigment removal and acne scar treatment; and when the second filter 3 is in the second position, the light output module performs the function of hair removal, and at the same time performs the functions of melanin pigment removal and acne scar treatment.

[0024] In another embodiment, the wavelength range through which the first filter 2 allows light to pass is between 530nm and 1200nm, and the wavelength range through which the second filter 3 allows light to pass is between 900nm and 1200nm, and light within the range of 900nm to 1200nm can be used for skin rejuvenation (also belonging to the category of beauty). That is, when the second filter 3 is in the first position, the light output module performs the function of skin rejuvenation, and when the second filter 3 is in the second position, the light output module performs the function of hair removal, and simultaneously performs the function of skin rejuvenation.

[0025] 1 to 3, the light output module further includes a fixed mounting base 5 and a switching holder 6, in which the first filter 2 and the light source 1 are spaced apart from each other along the second direction on the fixed mounting base 5, the light source 1 is an IPL lamp source, the light source 1 and the first filter 2 are both mounted on the fixed mounting base 5, the second filter 3 is mounted on the switching holder 6, the switching holder 6 is slidably mounted on the fixed mounting base 5 along the first direction, and the switching structure 4 is connected to the switching holder 6 and is used to move the switching holder 6 to slide on the fixed mounting base 5. The second direction is disposed at an angle to the first direction, for example, the first direction is the X direction in the figures, the second direction is the Y direction in the figures, and the first direction and the second direction are perpendicular to each other.

[0026] The switching structure 4 may be an electrically driven switching structure or a manually driven switching structure, for example, the switching structure 4 may include a rotary motor, which is power-transmittedly connected to the switching holder 6 and used to drive the switching holder 6 to move along the first direction. Alternatively, based on the switching frequency between the first and second positions of the second filter 3 and the manufacturing cost of the light output module, the switching structure 4 may include a switching push button, and a pressing force may be manually applied to the switching push button to move the switching holder 6 in the first direction, thereby switching the second filter 3 between the first and second positions.

[0027] A guide portion extending along the first direction is further provided on the fixed mounting seat 5 so that the switching holder 6 can stably slide on the fixed mounting seat 5, and the switching holder 6 slides along the guide portion on the fixed mounting seat 5. In one embodiment, the guide portion has a guide groove extending along the first direction, and the switching holder 6 is provided to slide within the guide groove.

[0028] Specifically, in order to reduce the difficulty of assembly, the fixed mounting seat 5 is provided separately and includes a first holder 51, a second holder 52, and a third holder 53, among which the first holder 51 and the second holder 52 are jointly enclosed and closed to form a position restriction space in which the first filter 2 and the light source 1 are attached, and the first holder 51 and the third holder 53 are jointly enclosed and closed to form a guide groove, which is located on one side of the position restriction space along the first direction and communicates with the position restriction space, and at least a portion of the switching holder 6 where the second filter 3 is attached can move from the guide groove into the position restriction space, thereby realizing switching between the first position and the second position of the second filter 3. More specifically, based on the installation of the switching push button, the third holder 53 is further provided with a retreat hole 531 extending along the first direction, and the switching push button is connected to the switching holder 6 by a connection part that penetrates the retreat hole 531 and is exposed from the outside of the fixed mounting seat 5.

[0029] In one embodiment, in order to maintain stability when the second filter 3 is in the first position and the second position, the fixed mounting seat 5 and the switching holder 6 are provided with a first positioning portion 511 and a second positioning portion 61, respectively, and when the second filter 3 is in the first position or the second position, the fixed mounting seat 5 and the switching holder 6 are fitted together by the engagement of the first positioning portion 511 and the second positioning portion 61.

Of course, when the external force received by the switching holder 6 is greater than a preset range, the positioning pin can be removed from the positioning groove to realize switching between the first position and the second position of the second filter 3.

[0030] Specifically, a sliding groove 512 which is not connected to the two positioning grooves is further provided between the two positioning grooves, the positioning pin can slide within the sliding groove 512, and the groove walls at both ends along the first direction of the sliding groove 512 are made into inclined guide surfaces for guiding the positioning pin into the positioning groove, thereby reducing the difficulty of the positioning pin entering the positioning groove.

[0031] In another embodiment, the first positioning portion 511 has a positioning groove, and the second positioning portion 61 has a positioning ball and a spring, and the spring stores elastic energy so that the positioning ball can be partially engaged in the positioning groove when the positioning ball faces the positioning groove, thereby realizing positioning between the switching holder 6 and the fixed mounting seat 5.

[0032] In one embodiment, the light-emitting module further includes a light-transmitting contact member 7 and a cooling member, the position control space is provided with an attachment port 54 at a position on one side of the first filter 2 facing away from the light source 1, the light-transmitting contact member 7 is attached to the attachment port 54 and located in the path of the light emitted by the light source 1 and used to contact the skin, both the first care light and the second care light can pass through the light-transmitting contact member 7 and be irradiated onto the skin of the human body, and the cooling member is used to reduce the temperature of the light-transmitting contact member 7 and improve the user's comfort. Specifically, the light-transmitting contact member 7 includes a sapphire crystal, the cooling member includes a semiconductor cooling sheet, and the cooling member and the light-transmitting contact member are connected by a thermally conductive silicone adhesive.

[0033] More specifically, a first mounting groove 513 is provided on the side of the first holder 51 facing the second holder 52, and a second mounting groove 521 is provided on the side of the second holder 52 facing the first holder 51, and the second holder 52 can be placed around the outside of the first mounting groove 513 to enclose and form the mounting opening 54. At the same time, the inner wall of the second mounting groove 521 abuts against the outer wall of the second mounting groove 521, which reduces the difficulty of assembling the first holder 51 and the second holder 52 to form the mounting opening 54.

[0034] In order to timely dissipate heat from the light source 1, the light output module further includes a heat sink 9 and a heat dissipation fan 30. The heat sink 9 is also located in the position control space and is located on one side facing the first filter 2 of the light source 1, and has a heat dissipation passage extending along a first direction.
