The first embodiment is different from the light-homogenizing decorative structure in that the decorative ring 42 is made of transparent or translucent material and has the light-homogenizing effect. A light guide lamp strip 44 is arranged below the decorative ring 42, the light guide lamp strip 44 is a multi-core optical fiber and is connected with an LED light source 45, the LED light source 45 has a large volume, is installed in a part, not installed on the decorative cover 13, in the upper cover 11, and then conducts light through the optical fiber.

The decorative ring 42 can reach the effect of a ring-shaped light belt by the light emitted by the light guide light belt 44.

Meanwhile, due to the design of the independent LED light source 45, the brightness of the LED light source is controlled to gradually change by the MCU, so that the effect of a breathing lamp is achieved, and the breathing lamp corresponds to the starting and working of equipment.

By adopting the scheme design of the second embodiment, the decorative brightness is directly emitted through the decorative ring 42, so that the decorative effect is better; the light source is hidden under the decorative ring 42, so that the light source can be better protected, and the whole air outlet channel 14 is smoother and smoother, which is beneficial to ventilation.

The decorative ring 42 may be adhered to the inside of the upper cover 11 by an adhesive, or may be mounted and fixed in the manner shown in the figure, a plurality of decorative ring mounting posts 4201 are provided on the back surface of the decorative ring 42, and a plurality of decorative ring fixing holes 4202 are correspondingly provided on the mounting position of the decorative ring 42 of the upper cover 11; when the decorative ring 42 is covered on the upper cover 11, the decorative ring mounting post 4201 is inserted into the decorative ring fixing hole 4202, and finally the decorative ring mounting post 4201 passes through the decorative ring fixing hole 4202, and is pressed by a press head to deform the decorative ring mounting post 4201, thereby achieving fixing.

The hand-held household laser beauty instrument has a laser dot matrix treatment effect, and meanwhile, the refrigeration unit 23 is arranged, so that the metal cap 2402 in contact with the skin is maintained at a certain temperature, the skin around a treatment area is synchronously cooled, the burning pain of the skin caused by laser treatment is relieved, and a therapist obtains a comfortable experience.

Because the cooling function is synchronously realized, the skin can be cooled, so that the laser energy density of the laser generator 22 can be improved, and the treatment effect of the handheld household laser beauty instrument can be further improved. Because the laser is a household device, the set laser energy density is low for safety, and the generation of too high temperature, which causes uncontrollable temperature, is prevented; the laser energy density of a professional laser beauty instrument adopted by a medical institution is about 2 times higher than that of a handheld household laser beauty instrument. When the hand-held domestic laser beauty instrument has the synchronous cooling measure, the energy density of some laser can be properly increased to improve the laser treatment effect.

The hand-held domestic laser beauty instrument increases the laser energy density and the refrigeration unit 23, so the power of the whole equipment is increased and the hand-held domestic laser beauty instrument can be maintained only by adopting a battery with a larger size and specification; therefore, a special battery mounting groove 2101 is formed in the middle of the control circuit board 21, so that a larger size battery can be mounted by using a hand-held part of the laser beauty instrument, and the power consumption requirement caused by power increase is met.

The hand-held domestic laser beauty instrument of the invention increases the laser energy density and adds the refrigeration unit 23, so the heat dissipation capacity of the whole instrument is also larger, and on the basis of installing the heat dissipation fins on two power devices which mainly need heat dissipation, the invention also combines the cooling fan 25 and designs a special heat dissipation channel to carry out high-efficiency heat dissipation. When heat is dissipated, outside room temperature air enters from the air inlet channel 15 at one side of the laser beauty instrument main machine close to the skin, so that the heat on the surface of the skin can be indirectly taken away, and the comfortable sensation of a curer is improved; after entering, the air passes through the laser heat dissipation fins 2204 and the refrigeration fin heat dissipation fins 2303 in the vertical direction, takes away the heat on the surfaces of the heat dissipation fins, and is finally discharged from the front surface of the laser beauty instrument main machine through the air outlet channel 14.

Because the upper cover 11 of the hand-held household laser beauty instrument is provided with the air outlet channel 14, in order to improve the aesthetic effect, the original function of the status indicator lamp is kept, the gap is fully utilized to integrate the button function, the decorative cover component 3 with the integration of the button switch function and the status display function is designed, and the gap of the air outlet channel 14 is utilized to arrange a circle of dodging decorative structure, so that the air outlet channel 14 is kept, the status indication function and the button switch function are kept, dodging decoration is added, and the integral aesthetic effect of the equipment is improved.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the embodiments disclosed, but is capable of various modifications and substitutions without departing from the spirit of the invention.
