[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that the terms "first", "second" and "one end" in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, products or devices.

[0029] See also Figure 1 and Figure 4 The embodiment of the utility model provides a skin treatment device 1. The skin treatment device 1 comprises: a housing 800, a skin treatment light source 100, a main control circuit board 603 and a knob assembly 700. A skin contact structure 820 is provided on the surface of the housing 800. The skin treatment light source 100 is provided in the housing 800, and the light emitted by the skin treatment light source 100 is emitted outward after passing through the skin contact structure 820. The main control circuit board 603 is provided in the housing 800, and the main control circuit board 603 is electrically connected to the skin treatment light source 100. The knob assembly 700 is provided and protrudes from the surface of the housing 800, and the knob assembly 700 is electrically connected to the main control circuit board 603; the knob assembly 700 can be rotated to control the light emission of the skin treatment light source.

[0030] In the skin treatment device 1 provided in the embodiment of the utility model, the skin contact structure 820 is used to contact the user's skin, and allows the light generated by the skin treatment light source 100 to be emitted and reach the user's skin and achieve a skin treatment effect. Specifically, the skin treatment light source 100 can be used to emit intense pulsed light, radio frequency light and other light with skin treatment functions such as freckle removal, skin rejuvenation, and hair removal. The knob assembly 700 arranged on the surface of the housing 800 has a rotation function, and the main control circuit board 603 electrically connects the knob assembly 700 and the skin treatment light source 100. Therefore, the user can send an electrical signal to the main control circuit board 603 by rotating the knob assembly 700, thereby controlling the operating state of the skin treatment light source 100. For example, when the knob assembly 700 is in the initial state, the skin treatment light source 100 is in a stopped state; when the user rotates the knob assembly 700, the skin treatment light source 100 starts to work, and as the user continues to rotate the knob assembly 700 in the same direction, the light intensity of the skin treatment light source 100 increases, or changes its working mode such as its light intensity and light frequency. Under this premise, when the user rotates the knob assembly 700 in the opposite direction to the initial state, the skin treatment light source 100 stops working.

[0031] In summary, the skin treatment device 1 provided by the embodiment of the utility model achieves the technical effect of controlling the switch and working mode of the skin treatment light source 100 by rotation by setting the knob assembly 700. Therefore, it avoids the design of setting multiple buttons on the skin treatment device 1 or requiring the user to press the same button multiple times to set the skin treatment light source 100 to the target working mode. Therefore, the skin treatment device 1 can replace multiple buttons with a single knob assembly 700 with a rotation function, thereby simplifying the control structure on the surface of the skin treatment device 1 and providing the user with a convenient and intuitive way to control the skin treatment device 1.

[0032] Further, see Figure 2 The knob assembly 700 includes: a rotating member 720 and a central functional member 740. The rotating member 720 is arranged around the central functional member 740. The rotating member 720 can rotate relative to the central functional member 740, or the rotating member 720 can drive the central functional member 740 to rotate. Specifically, the central functional member 740 has functions such as light indication and touch control. The rotating member 720 can be rotatably connected to the central functional member 740 through a sliding groove structure, or the rotating member 720 is clamped with the central functional member 740, so that the rotating member 720 can drive the central functional member 740 to rotate.

[0033] Furthermore, if Figure 2 As shown, the central functional part 740 is a screen display part. That is, the knob assembly 700 includes a rotating part 720 and a screen display part. The rotating part 720 is arranged around the screen display part. The screen display part is, for example, a small LED light-emitting screen or other similar devices that can play a screen display function. The screen display part can, for example, inform the user that the skin treatment device 1 is working by emitting light, and reflect the luminous intensity of the skin treatment light source 100 through its luminous intensity. The screen display part can also inform the user of the working state of the skin treatment device 1 by emitting light of different colors, or inform the user of the working state of the skin treatment device 1 by displaying text, symbols, patterns and other contents.

[0034] Furthermore, the screen display component may be, for example, a screen display touch control, that is, the screen display touch control may respond to a user's pressing action. The screen display touch control may be, for example, a capacitive screen. When the user presses the capacitive screen, the capacitive screen generates a weak current signal, which is sent to the main control circuit board 603, so that the user can control the skin treatment device 1.

[0035] In addition, in another embodiment of the present invention, the central functional part 740 is, for example, a pressing part. The rotating part 720 is arranged around the pressing part. The signal conversion part 760 may also be provided with a button. The button abuts against the pressing part. The user may press the button by pressing the pressing part. The button may convert pressure into an electrical signal.

[0036] When the central functional part 740 is used as a screen touch control or a pressing part, the knob assembly 700 can have both pressing and rotating functions, so as to achieve the technical effect of allowing users to combine different operation modes to control the skin treatment device 1. For example, after the screen touch control or the pressing part is pressed by the user, the skin treatment light source 100 will be turned on or off. When the skin treatment light source 100 is in the on working state, the user can adjust the working intensity or working mode of the skin treatment light source 100 by rotating the rotating part 720.

[0037] Further, see Figure 3When the central functional part 740 is used as a pressing part, it can also be, for example, a light-transmitting structure, and the knob assembly 700 further includes a signal converter 760. The signal converter 760 is disposed in the housing 800, and the signal converter 760 is electrically connected to the main control circuit board 603. The light-transmitting structure is connected to and disposed on a side of the signal converter 760 away from the housing 800. The signal converter 760 is, for example, provided with a light source such as an LED, and can convert an electrical signal from the main control circuit board 603 into light. The light is transmitted to the outside of the housing 800 through the light-transmitting structure. At this time, the light-transmitting structure is used as a screen display component and can also be used as a pressing component in combination with the button in the signal converter 760.

[0038] Further, see Figure 3 The signal conversion part 760 is provided in the housing 800 and is electrically connected to the main control circuit board 603. The signal conversion part 760 is connected to the pressing part and the rotating part 720. The signal conversion part 760, for example, has an LED light source and a button as described above, and the signal conversion part 760 can also be provided with a rotary potentiometer, and the rotary potentiometer converts the rotation signal of the rotating part 720 into an electrical signal. The pressing and rotating functions can also be integrated into the same potentiometer, that is, a potentiometer with a pressing switch and a rotating switch.

[0039] In the above embodiment, the pressing function and the screen display function can be realized by the same structure. In another embodiment, the pressing function and the screen display function can also be realized by different structures. For example, the knob assembly includes a screen display part and a pressing part. The screen display part is arranged around the pressing part; the rotating part 720 is arranged around the screen display part. That is, the pressing part is at the center of the screen display part and the rotating part, and the screen display part is annular, and the outermost side of the knob assembly 700 is the rotating part 720.

[0040] In the embodiment of the utility model, when the rotating member 720 is rotatably connected to the central functional member 740, the rotating member 720 is, for example, formed with a first limiting structure 722, and the central functional member 740 is, for example, formed with a second limiting structure 742. When the rotating member 720 is rotated to the first state or the second state relative to the central functional member 740, the first limiting structure 722 and the second limiting structure 742 are in contact. When the rotating member 720 is rotated to the third state relative to the central functional member 740, the first limiting structure 722 and the second limiting structure 742 are separated.

[0041] Specifically, when the rotating member 720 is in the first state relative to the central functional member 740, the position of the first limiting structure 722 relative to the second limiting structure 742 is as follows: Figure 5bIf the user rotates the rotating member 720, the first limiting structure 722 rotates accordingly, and the first limiting structure 722 is in a position relative to the second limiting structure 742 as shown. Figure 5a When the rotating member 720 rotates further, the first limiting structure 722 finally abuts against the second limiting structure 742, and Figure 5c shown.

[0042] Since the rotation function of the rotating member 720 can be used to adjust the working intensity or working mode of the skin treatment light source 100. Therefore, by setting the first limiting structure 722 and the second limiting structure 742, the working intensity of the skin treatment light source 100 can be distributed from the weakest to the strongest within the range of one rotation of the rotating member 720, or the different working modes of the skin treatment light source 100 can be distributed within the range of one rotation of the rotating member 720. Therefore, when the user rotates the rotating member 720 to adjust the working intensity of the skin treatment light source 100, the rotating member 720 will not be over-rotated, for example, the rotating member 720 needs to be rotated for multiple cycles to adjust to the required working intensity or working mode, or the working intensity of the skin treatment light source 100 will jump (for example, from the strongest to the weakest) after the rotating member 720 rotates for more than one cycle. Therefore, the setting of the first limiting structure 722 and the second limiting structure 742 makes the operation of the knob assembly 700 more humane.

[0043] Further, see Figure 6 The knob assembly 700 is provided with an indicator mark, and the housing 800 is provided with a pointer 840, and the pointer 840 points to the knob assembly 700. The indicator mark is, for example, provided on the rotating member 720. The indicator mark and the pointer 840 cooperate to provide a user with a reference for the rotation amplitude, so that the user can know the working state of the skin treatment light source 100 by observing the knob assembly 700.

[0044] In addition, it can be understood that the aforementioned embodiments are merely illustrative descriptions of the present invention. Under the premise that the technical features do not conflict, are not contradictory, and do not violate the utility model purpose of the present invention, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
