[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in combination with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Combined with the embodiments and the attached Figures 1-4 , a laser beauty practice device includes a bionic practice board and a practice target. The bionic practice board includes an epidermis layer 1, a dermis layer 2, and a fat layer 3 arranged in sequence from top to bottom. A plurality of first grooves 41 are recessed on the upper surface of the bionic practice board, and the practice target is placed in the first grooves 41; the practice target includes a plurality of light-transmitting bodies 51 and absorbing bodies 52, and there is a contact surface between the light-transmitting bodies 51 and the absorbing bodies 52 in the first grooves, so that the absorbing bodies 52 are thermally welded and adhered to the light-transmitting bodies 51 after being irradiated by laser; both the light-transmitting bodies 51 and the bionic practice board are made of high transmittance materials, and the absorbing bodies 52 are made of high absorption rate materials.

[0020] The absorber 52 is mixed with laser sensitizer particles, and the laser sensitizer is carbon black. Alternatively, the absorber is pigment-stained so that the absorber is a melanin-like color absorber in brown or grayish black.

[0021] Both the bionic practice board and the light-transmitting body are made of transparent plastic, and the transparent plastic is PMMA or PC, which is convenient for quickly identifying the absorber 52 in the practice target. The thickness of the epidermis layer is 2 - 3 mm, the thickness of the dermis layer is 3 - 5 mm, and the thickness of the fat layer is 9 - 11 mm. The bionic practice board and the light-transmitting body can also be selected from one or more of ABS, LDPE, HDPE, PVC, Nylon 6, Nylon 66, and PS resin, and are molded to fit the skin touch and enhance the softness of the bionic practice board.

[0022] Further, the absorber can be selected from one or more of PBT, PS, PVC, or PP, and the melting point of the absorber is close to or the same as the melting point of the light-transmitting body.

[0023] Further, the absorber is black Nylon 66 particles, and the light-transmitting body is transparent Nylon 66 particles.

[0024] The bottom wall of the first groove 41 is located in the epidermis layer 1 or the dermis layer 2, which is the area where the lesion 50 of the pseudo-junctional nevus or mixed hemorrhoid is located. When in use, the bionic practice board is fixed under the laser emitting head. First, the light-transmitting body 51 is laid as a protective bottom layer in the first groove 41, and then the absorber 52 and the remaining light-transmitting body 51 are laid or scattered according to the type of lesion to be practiced, completing the assembly of the practice target. During practice, the emission path of the laser emitting head sequentially passes through the light-transmitting body 51 - absorber 52 - light-transmitting body 51 located in the protective bottom layer. After the absorber 52 is irradiated by the laser, it melts and adheres to the light-transmitting body 51, and the operator can obtain practice feedback according to the state of the light-transmitting body adhered to the surface of the absorber after laser irradiation. The light-transmitting body and the absorber can be adjusted to mimic the state according to the type of lesion to form lesions such as pseudo-junctional nevus, freckles, and melasma.

[0025] The epidermis layer 1 and the dermis layer 2 are detachably connected. The upper surface of the dermis layer 2 is concave to form a second groove 42 for placing the practice target, and there is a gap between the bottom wall of the second groove 42 and the upper surface of the fat layer 3. The second groove 42 is the area where the lesion of the pseudo-intradermal nevus is located.

[0026] Further, the epidermis layer and the dermis layer are connected by plugging.

[0027] Both the light-transmitting body 51 and the absorber 52 are granular bodies, and the outer diameter of the absorber 52 does not exceed 3 mm, which is convenient for simulating various types of spots.

[0028] Both the light-transmitting body 51 and the absorber 52 are sheet bodies, and the light-transmitting body 51 is laid under the absorber 52, which is convenient for simulating large-area lesions and is suitable for fractional laser practice.

[0029] The bottom of the fat layer 3 is detachably connected to the protective bottom plate 6, and the protective bottom plate is made of a low-light-transmitting material to protect the operating table.

[0030] Furthermore, the protective bottom plate 6 is inserted and connected to the fat layer through a vertical telescopic rod, and a positioning lock is provided on the vertical telescopic rod to adjust the height of the vertical telescopic rod. The number of vertical telescopic rods is not less than two. Adjusting the height of the vertical telescopic rod through the positioning lock realizes the inclination of the bionic practice board to restore the curved surface inclination angles of different parts of the face.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
