Technical Field

[0001] This utility model relates to the field of medical aesthetics technology, and in particular to a beauty device. Background Technology

[0002] In existing technology, optical beauty devices include a housing, a cooling unit, and an emitter. The cooling unit is partially exposed on the surface of the housing and is made of a crystalline material. The emitter is housed inside the housing and located on the side of the cooling unit away from contact with the body. The light emitted by the emitter passes through the cooling unit, positioning the emitter on the side of the cooling unit away from contact with the body. While the cooling unit provides both light transmission and cooling effects, it does not focus the light. It requires a reflector to concentrate the light from the emitter towards the cooling unit, which increases structural complexity and cost. Utility Model Content

[0003] The main purpose of this invention is to provide a beauty device that reduces structural complexity while concentrating emitted light to save costs.

[0004] To achieve the above objectives, this utility model proposes a beauty device, comprising:

[0005] The outer casing is equipped with a light emission channel;

[0006] The main circuit board is located inside the housing;

[0007] The light-emitting module is installed inside the housing and located at the inner end of the light-emitting channel;

[0008] A convex focusing lens, disposed within the light emission channel, is used to concentrate the light emitted by the light-emitting module and direct it onto the skin in a rectangular strip shape; and

[0009] A cooling fan is mounted on the main circuit board and electrically connected to the main circuit board.

[0010] Optionally, the outer casing forms a tapered end of the light emission channel, and the outer end of the light emission channel has a rectangular opening.

[0011] Optionally, the beauty device further includes an image sensor, which is disposed on one end of the housing where the light emission channel is located and electrically connected to the main circuit board. The image sensor is used to acquire skin images of the treatment area.

[0012] Optionally, the beauty device further includes a wireless communication module, which is electrically connected to or integrated on the main circuit board and is used to establish wireless communication with the terminal device.

[0013] Optionally, the image sensor is a CCD sensor or a CMOS sensor.

[0014] Optionally, the wireless communication module is a WIFI module, a Bluetooth module, or a 2G / 3G / 4G / 5G / 6G module.

[0015] Optionally, the outer casing is provided with ventilation holes at positions corresponding to the air inlet and air outlet of the cooling fan. The beauty device also includes heat dissipation fins, which are installed on one side of the cooling fan, and the light-emitting module is attached to the heat dissipation fins.

[0016] Optionally, the beauty device also includes a rechargeable battery, which is installed inside the housing and electrically connected to the main circuit board. The housing is provided with a charging interface, which is electrically connected to the rechargeable battery.

[0031] This utility model proposes a beauty device.

[0032] Reference Figures 1 to 3 In one embodiment of this utility model, the beauty device includes a housing 10, a main circuit board 20, a light-emitting module 30, a condensing lens 40, and a cooling fan 50; the housing 10 is provided with a light-emitting channel 10a; the main circuit board 20 is disposed inside the housing 10; the light-emitting module 30 is installed inside the housing 10 and located at the inner end of the light-emitting channel 10a; the condensing lens 40 is disposed inside the light-emitting channel 10a, and the condensing lens 40 is used to concentrate the light emitted by the light-emitting module 30 and make it fall on the skin in a rectangular strip shape; the cooling fan 50 is mounted on the main circuit board 20 and electrically connected to the main circuit board 20.

[0033] In this embodiment, the outer shell 10 may be assembled from a front shell, a rear shell, and end caps, etc., and is not limited here.

[0034] In this embodiment, the light-emitting module 30 can be a laser chip capable of emitting laser light with a wavelength of 600-1200nm, etc., to give the beauty device a better hair removal effect. Preferably, the laser chip emits a laser wavelength of 808nm. In addition to the laser chip, the light-emitting module 30 can also be an LED light, IPL or other light-emitting modules, or a combination of multiple light-emitting modules. Preferably, one end of the housing 10 forming the light emission channel 10a can be tapered, and the outer end of the light emission channel 10a has a rectangular opening. This is beneficial for adapting to the skin at different locations on the body, avoiding treatment blind spots, making a single treatment more thorough, and reducing repeated operations.

[0036] It is understood that this invention improves the structure of the beauty device. By setting a focusing convex lens 40, the emitted light is focused, causing the light to fall on the skin in a rectangular strip shape, which can be applied to different skin locations and reduces treatment blind spots. Furthermore, the cooling fan 50 greatly improves the heat dissipation effect of the internal components of the beauty device, thus enhancing the laser hair removal effect. In addition, the light-emitting module 30 of this invention uses a laser chip, which greatly simplifies the light-emitting structure, reduces heat generation, and has low energy consumption and no irritating noise.

[0037] To further improve heat dissipation, refer to Figures 1 to 3 In one embodiment, the laser beauty device may further include heat dissipation fins 60, which are mounted on a support frame 80 and located on one side of the cooling fan 50.

The beauty device also includes heat dissipation fins 60, which are installed on one side of the cooling fan 50, and the light-emitting module 30 is attached to the heat dissipation fins. This further improves the heat dissipation effect and makes installation more convenient.

[0039] In one embodiment, such as Figures 1 to 3 As shown, the beauty device also includes an image sensor (not shown). The image sensor is located on one end of the housing 10 where the light emission channel 10a is provided and is electrically connected to the main circuit board 20. The image sensor is used to acquire skin images of the treatment area.

[0040] In this embodiment, the beauty device also includes a wireless communication module (not shown in the figure). The wireless communication module is electrically connected to or integrated on the main circuit board 20 and is used to establish wireless communication with the terminal device.

[0041] Preferably, the image sensor can be a CCD sensor or a CMOS sensor, etc. The wireless communication module can be a WIFI module, a Bluetooth module, or a 2G / 3G / 4G / 5G / 6G module, etc., which is not limited here.

[0042] This invention enables image acquisition of the treatment area by setting an image sensor, and transmits the image signal to the user's mobile phone or tablet or other terminal device through a wireless communication module, so that the user can view the hair removal progress of the hair removal area in real time.

[0043] For ease of use, in one embodiment, the beauty device may further include a rechargeable battery 70, which is installed inside the housing 10 and electrically connected to the main circuit board 20. The housing 10 is provided with a charging interface 71, which is electrically connected to the rechargeable battery 70.

[0044] In one embodiment, such as Figure 3 As shown, the beauty device may also include a support frame 80, which has a first mounting part, a second mounting part, and a third mounting part. The first mounting part and the second mounting part are located on the same side of the support frame 80, and the third mounting part is located on the other side of the support frame 80. The cooling fan 50 is mounted on the first mounting part, the rechargeable battery 70 is mounted on the second mounting part, and the main circuit board 20 is mounted on the third mounting part. In this way, the rechargeable battery 70, the cooling fan 50, and the main circuit board 20 can be installed conveniently, while effectively improving the space utilization inside the outer casing 10 and ensuring that heat can be dissipated at a relatively fast rate.

[0045] Furthermore, in one embodiment, such as Figure 1 As shown, the beauty device may also include a contact sensor 90, which is located at the opening of the light emission channel 10a and electrically connected to the main circuit board 20 or the light-emitting module 30.
