[0026] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0027] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0030] Reference Figures 1 - 8As shown, in the embodiment of the utility model, a light output module is proposed, including a light source 1, a first filter 2, a second filter 3 and a switching structure 4, the first filter 2 is fixedly arranged on the light path emitted by the light source 1, the second filter 3 includes a first position and a second position, when in the first position, the second filter 3 is on the light path emitted by the light source 1, 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 staggered with the light path 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 to drive the second filter 3 to switch between the first position and the second position. It should be emphasized that the wavelength range that the second optical filter 3 allows light to pass through overlaps with the wavelength range that the first optical filter 2 allows light to pass through, so that the light output module forms the first care light and the second care light respectively when the first optical filter 2 and the second optical filter 3 are superimposed and when the first optical filter 2 is not superimposed with the second optical filter 3. Obviously, the function that the second care light can play when irradiated on the skin can cover the function that the first care light can play when irradiated on the skin, but the second care light and the first care light have different effects when irradiated on the skin.

[0031] The above-mentioned light output module is equipped with a first filter 2 and a movable second filter 3, so that the entire light output module can emit light of two different bands. When it is used in a skin care device, two different skin care functions can be achieved without replacing the head, saving space and avoiding the risk of losing the head.

[0032] In one embodiment, the first filter 2 allows light to pass through a wavelength range of 530nm-1200nm, and the light within this range can play a role in beauty and hair removal. The second filter 3 allows light to pass through a wavelength range of 500nm-650nm. The light within this range also contains the absorption peaks of melanin, oxygen and hemoglobin, and can therefore be used to remove melanin and acne marks (belonging to the category of beauty). That is, when the second filter 3 is in the first position, the light output module plays a role in removing melanin and acne marks. When the second filter 3 is in the second position, the light output module plays a role in hair removal. While removing hair, it can also play a role in removing melanin and acne marks.

[0033] In other embodiments, the wavelength range of light allowed to pass through the first filter 2 is between 530 nm and 1200 nm, and the wavelength range of light allowed to pass through the second filter 3 is between 900 nm and 1200 nm. The light within the range of 900 nm - 1200 nm can be used for skin rejuvenation (which also belongs to the category of beauty). That is, when the second filter 3 is in the first position, the light-emitting module functions for skin rejuvenation. When the second filter 3 is in the second position, the light-emitting module functions for hair removal, and at the same time of hair removal, it can also function for skin rejuvenation.

[0034] Refer to Figures 1 - 3 As shown, the light-emitting module further includes a fixed mounting base 5 and a switching bracket 6. The first filter 2 and the light source 1 are arranged at intervals along the second direction on the fixed mounting base 5. The light source 1 is an IPL light source. Both the light source 1 and the first filter 2 are arranged on the fixed mounting base 5. The second filter 3 is arranged on the switching bracket 6. The switching bracket 6 is slidably arranged along the first direction on the fixed mounting base 5. The switching structure 4 is connected to the switching bracket 6 to drive the switching bracket 6 to slide on the fixed mounting base 5. The second direction and the first direction are arranged at an angle. For example, the first direction is the X direction in the figure, and the second direction is the Y direction in the figure. The first direction and the second direction are perpendicular.

[0035] It can be understood that the switching structure 4 can be either an electrically driven switching structure or a manual switching structure. For example, the switching structure 4 includes a rotating motor, and the rotating motor is in transmission connection with the switching bracket 6 to drive the switching bracket 6 to move along the first direction. Or, considering the switching frequency of the second filter 3 between the first position and the second position and the manufacturing cost of the light-emitting module, the switching structure 4 includes a switching push button. By manually applying a driving force to the switching push button, the switching bracket 6 is moved in the first direction, thereby realizing the switching of the second filter 3 between the first position and the second position.

[0036] In order to enable the switching bracket 6 to slide stably on the fixed mounting base 5, a guiding portion extending along the first direction is further provided on the fixed mounting base 5. The switching bracket 6 slides on the fixed mounting base 5 along the guiding portion. In one embodiment, the guiding portion includes a guiding groove extending along the first direction, and the switching bracket 6 is slidably arranged in the guiding groove.

[0037] Specifically, to reduce the assembly difficulty, the fixed mounting base 5 is provided in a split manner, including a first bracket 51, a second bracket 52, and a third bracket 53. Among them, the first bracket 51 and the second bracket 52 jointly enclose a limiting space for mounting the first filter 2 and the light source 1. The first bracket 51 and the third bracket 53 jointly enclose a guiding groove, which is located on one side of the limiting space along the first direction and communicates with the limiting space. At least a part of the switching bracket 6 on which the second filter 3 is mounted can move from the guiding groove into the limiting space to realize the switching of the second filter 3 between the first position and the second position. More specifically, based on the setting of the switching push button, an avoidance hole 531 extending along the first direction is further provided on the third bracket 53. The switching push button is connected to the switching bracket 6 through a connecting portion that penetrates into the avoidance hole 531 and exposes outside the fixed mounting base 5.

[0038] In one embodiment, to maintain the stability of the second filter 3 when it is in the first position and the second position, a first positioning portion 511 and a second positioning portion 61 are respectively provided on the fixed mounting base 5 and the switching bracket 6. When the second filter 3 is in the first position or the second position, the fixed mounting base 5 and the switching bracket 6 are clamped and matched through the first positioning portion 511 and the second positioning portion 61. In one embodiment, the first positioning portion 511 is provided on the first bracket 51 and is located in the guiding groove. The first positioning portion 511 includes a positioning groove, and two positioning grooves are arranged at intervals along the first direction. The second positioning portion 61 includes a positioning pin. When the switching bracket 6 moves along the first direction, the positioning pin can be clamped into the positioning groove to achieve positioning. Of course, when the external force applied to the switching bracket 6 is greater than the preset range, the positioning pin can be disengaged from the positioning groove to realize the switching of the second filter 3 between the first position and the second position.

[0039] Specifically, a sliding groove 512 that is not connected to the positioning groove is further provided between the two positioning grooves. The positioning pin can slide in the sliding groove 512. The groove walls at both ends of the sliding groove 512 along the first direction are provided as inclined guiding surfaces to guide the positioning pin into the positioning groove and reduce the difficulty of the positioning pin entering the positioning groove.

[0040] In other embodiments, the first positioning portion 511 includes a positioning groove, and the second positioning portion 61 includes a positioning ball and a spring. The spring stores elastic potential energy and can partially insert the positioning ball into the positioning groove when the positioning ball is aligned with the positioning groove, so as to realize the positioning between the switching bracket 6 and the fixed mounting base 5.

[0041] In one embodiment, the light output module further includes a light-transmitting contact member 7 and a cooling member. The limiting space is located on the side of the first filter 2 facing away from the light source 1 and is provided with an installation port 54. The light-transmitting contact member 7 is installed on the installation port 54 and is located on the light path emitted by the light source 1. The light-transmitting contact member 7 is 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 irradiate the human skin. The cooling member is used to reduce the temperature of the light-transmitting contact member 7 to 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 is connected to the light-transmitting member through thermally conductive silicone.

[0042] More specifically, a first mounting groove 513 is provided on one side of the first bracket 51 facing the second bracket 52, and a second mounting groove 521 is provided on one side of the second bracket 52 facing the first bracket 51. The second bracket 52 can be covered outside the first mounting groove 513 to enclose and form a 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 to reduce the difficulty of assembling the first bracket 51 and the second bracket 52 to form the mounting opening 54.

[0043] In order to dissipate heat for the light source 1 in time, the light output module also includes a heat sink 9 and a heat dissipation fan 30. The heat sink 9 is also located in the limited space and on the side of the light source 1 facing away from the first filter 2. The heat sink 9 has a heat dissipation channel extending along the first direction. The heat dissipation fan 30 is located on one side of the heat dissipation channel along the first direction to accelerate heat dissipation. Specifically, the heat sink 9 includes a heat sink body 91 and a mounting plate 92. The heat sink body 91 is fixed on the mounting plate 92. The mounting plate 92 is fixed to the first bracket 51 by screw locking. The second bracket 52 is located between the first bracket 51 and the mounting plate 92. The second bracket 52 is fixed to the first bracket 51 through the mounting plate 92. The first bracket 51 is also provided with a third mounting groove 514 for limiting and fixing the heat dissipation fan 30. The bottom of the third mounting groove 514 is provided with an air port for air flow.

[0044] Specifically, a limiting block 522 is provided on the side of the second bracket 52 facing the mounting plate 92, and the two limiting blocks 522 are spaced apart along the first direction to form a limiting groove, and the mounting plate 92 is at least partially embedded in the limiting groove, thereby reducing the difficulty of screwing the mounting plate 92 and the first bracket 51.

[0045] When the switching bracket 6, the light source 1, the first filter 2 and the second filter 3 are assembled on the fixed mounting base 5, first place the light source 1 and the first filter 2 on the first bracket 51, then cover the second mounting groove 521 on the second bracket 52 over the notch of the first mounting groove 513, lock the mounting plate 92 on the first bracket 51 to limit the first filter 2 and the second bracket 52, and then place the switching bracket 6 on the first bracket 51 and lock the third bracket 53 on the first bracket 51 to enclose and form a guiding groove.

[0046] In one embodiment, the light-emitting module further includes a control circuit board 8 electrically connected to the light source 1, and the control circuit board 8 is used to control the light source 1.

[0047] In one embodiment, the light-emitting module further includes an indicating member and a monitoring member 10. Both the monitoring member 10 and the indicating member are electrically connected to the control circuit board 8. At this time, the control circuit board 8 can also control the monitoring member 10 and the indicating member. The monitoring member 10 is stationary relative to the first filter 2. For example, the monitoring member 10 is disposed on the fixed mounting base 5. The monitoring member 10 can form a preset first induction signal and a preset second induction signal when the second filter 3 is in the first position and the second position respectively, that is, the monitoring member 10 can monitor whether the second filter 3 is in the first position or the second position.

[0048] Taking the monitoring member 10 including Hall elements and the indicating member including indicator lights as an example, two Hall elements are arranged at intervals along the first direction, and a magnet 20 is also arranged on the switching bracket 6. When the second filter 3 is in the first position, one of the Hall elements generates a first induction signal in response to the magnet 20, and the control circuit board 8 instructs the corresponding indicator light to turn on or instructs the indicator light to feedback a corresponding color; when the second filter 3 is in the second position, the other Hall element generates a second induction signal in response to the magnet 20, and the control circuit board 8 instructs the other indicator light to turn on or instructs the indicator light to feedback another corresponding color.

[0049] In other embodiments, the monitoring member 10 includes a distance sensor, and the indicating member includes a sound indicating member.

[0050] The arrangement of the monitoring member 10 and the indicating member in the above embodiments enables the user to determine whether the first filter 2 is in the first position or the second position during use, so as to determine the function of the current light-emitting module.

[0051] In an embodiment of the present invention, a skin care device is further proposed, which includes a housing 40 and the above light-emitting module. The light-emitting module is disposed inside the housing 40. An light-emitting opening 401 for the light emitted by the light source 1 to pass through is formed on the housing 40. The light-transmitting contact member 7 penetrates into the light-emitting opening 401 and the contact surface for contacting the skin is flush with or protrudes from the outer surface of the housing 40. The switching push button is located outside the housing 40.

[0052] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model.
