Technical Field
[0001] This application relates to the technical field of beauty devices, and particularly to a cooling and repair module for a laser beauty device and its beauty operation method. Background Art
[0002] Fotona 4Dpro, also known as a non-invasive sculpting laser system, is a beauty device with multi-national certifications and extremely high safety. Inside the device, it is composed of two laser emitters that can emit two wavelengths of 2940nm and 1064nm, one deep and one shallow. By covering specific areas with different modes of laser, it can improve skin aging.
[0003] In order to protect the skin surface from being damaged by laser irradiation during the beauty process, a cooling module with a cooling effect on the skin is usually required. Among them, the carbon dioxide cooling module is relatively commonly used. Dry ice is in contact with water to quickly sublimate dry ice into low-temperature carbon dioxide gas, which jets onto the laser irradiation area to play a role in cooling and antioxidant. However, the low-temperature carbon dioxide gas contacts the air and condenses the moisture in the air to form fog, which diffuses to the laser irradiation area. The laser scatters in the fog, resulting in uneven light beams and poor treatment effects. In view of the above related technologies, the applicant proposes a cooling and repair module for a laser beauty device, which can isolate the cold air from the air and can cool the laser irradiation area directionally to prevent skin damage. Summary of the Invention

[0036] The following further describes the present application in detail with reference to the accompanying drawings.
[0037] The embodiment of the present application discloses a laser beauty instrument cooling and repair module and its beauty operation method. Referring to Figure 1 、 2 , it includes an operating cantilever 1 with a boosting function. The front end of the operating cantilever 1 is movably connected to a laser emission module 2. By controlling the laser emission module 2 through the operating cantilever 1, the operation is made more stable and the user is more relaxed.
[0038] Referring to Figure 2 、 3 , a positioning bracket 3 that abuts against the skin extends in the emission end direction of the laser emission module 2. The positioning bracket 3 facilitates the positioning of the laser and the maintenance of the distance. A cooling structure 4 for circulating low-temperature carbon dioxide gas is provided on the abutting end of the operating cantilever 1 extending to the positioning bracket 3. The cooling structure 4 includes a cooling air pipe 41 and a cooling air duct 42. The cooling air pipe 41 extends from the end of the operating cantilever 1 to the side wall of the positioning bracket 3, and a gas supply structure 11 is provided at one end of the cooling air pipe 41 corresponding to the operating cantilever 1.
[0039] Referring to Figure 2 、 4, the air supply structure 11 includes a sealed box 111, a partition 112, a heating wire 113 and a pressure valve 114. Dry ice is placed in the sealed box 111 to prevent water vapor in the atmosphere from entering the sealed box 111. The partition 112 is placed and fixed in the sealed box 111, and the dry ice is placed above the partition 112. The cooling air pipe 41 penetrates and communicates with the inside of the sealed box 111. The heating wire 113 is fixed to the sealed box 111 and is located below the partition 112. The pressure valve 114 penetrates the sealed box 111. The dry ice is heated by the heating wire 113 and quickly sublimes from a solid to a gas, forming a low-temperature cold gas with an increased volume, and enters the cooling air pipe 41 through the generated pressure. When the air pressure in the box is too high, the pressure valve 114 opens to prevent explosion due to excessive pressure.
[0040] Refer to Figure 3 , the cooling air pipe 41 is formed with a thin-channel structure 5 for reducing the gas thickness corresponding to the abutting end of the positioning bracket 3. The thin-channel structure 5 includes upper and lower opposed glass flakes 51 mounted on the abutting end of the positioning bracket 3. The two side glass flakes 51 and the positioning bracket 3 form a cooling cavity 8. The light emitted by the laser emission module 2 can pass through the glass flakes 51 and the thinner cooling gas in the cooling cavity 8 and irradiate the skin, weakening the heat dissipation and refraction effects of the gas on the laser, making the laser act on the skin more precisely.
[0041] Refer to Figure 3 , 5 , for more hygienic use, the lower glass flake 51 adopts a detachable replacement structure. The thickness of the glass flake 51 is set corresponding to the thickness of the cooling cavity 8, so that while the glass flake 51 meets the requirements of disassembly, the thickness of the cooling cavity 8 is reduced as much as possible. The glass flake 51 is connected to the inside of the positioning bracket 3 in a lifting manner. A step is formed on the outer edge of the glass flake 51 to abut against the inner side of the positioning bracket 3. The inner side penetrates the positioning bracket 3. A mounting opening 9 for the glass flake 51 to pass through is horizontally opened on the side wall of the positioning bracket 3 corresponding to the height of the cooling cavity 8. Push the glass flake 51 upward into the cooling cavity 8, and then slide the glass flake 51 horizontally, and the glass flake 51 can be taken out from the mounting opening 9 and a new glass flake 51 can be replaced.
[0042] Refer to Figure 5 , 6, an installation component 10 for keeping the glass sheet 51 stable is provided on the positioning bracket 3. The installation component 10 includes a positioning ring 101, a positioning step 102, and an installation snap ring 103. The positioning ring 101 is horizontally inserted through the installation opening 9 and is annularly arranged along the inner side of the positioning bracket 3, and the positioning ring 101 is positioned on the positioning bracket 3 in the vertical direction of the horizontal plane along the sliding direction; the positioning step 102 is fixed at the outer wall of the positioning ring 101 away from the installation opening 9, the positioning step 102 is horizontally inserted through the inner side wall of the positioning bracket 3 and forms a vertical positioning; the installation snap ring 103 is fixed on the side of the positioning ring 101 corresponding to the installation opening 9, the installation snap ring 103 is arc-shaped and elastic, the installation snap ring 103 is sleeved and buckled on the outer wall of the positioning bracket 3 along the sliding direction of the positioning ring 101. Through the cooperation of the positioning ring 101, the positioning step 102, and the installation snap ring 103, a three-axis positioning is formed between the positioning ring 101 and the positioning bracket 3, and the lower glass sheet 51 is positioned through the cooperation of the positioning bracket 3 and the positioning ring 101, ensuring that the lower glass sheet 51 can still remain stable when abutting against the skin.
[0043] Refer to Figure 3 , and at the same time, since the lower glass sheet 51 can abut against the skin, when the lower glass sheet 51 is precooled, the condensed water generated will contact the skin and be absorbed by the skin, thereby avoiding the formation of water droplets on the lower glass sheet 51 and affecting the efficiency of the laser. At the same time, the condensed water can play a role in lubricating and moisturizing.
[0044] Refer to Figure 7 , 8 , condensed water will be generated on the upper glass sheet 51 due to contact with air. In order to eliminate the condensed water, an anti-condensation structure 7 is provided at the upper glass sheet 51. The anti-condensation structure 7 includes a rotary bearing 71. The rotary bearing 71 is sleeved on the upper glass sheet 51, and the outer side of the rotary bearing 71 is accommodated and fixed in the positioning bracket 3. The upper glass sheet 51 rotates relative to the positioning bracket 3. By rotating the glass sheet 51, the air on the surface of the glass sheet 51 can be accelerated to flow and the moisture can volatilize. At the same time, even if water droplets are formed, the centrifugal force generated by the rotation of the glass sheet 51 can make the water droplets fall to the edge of the glass sheet 51.
[0045] Refer to Figure 1 , 2 , the anti-condensation structure 7 further includes a driving impeller 72 for driving the glass sheet 51 to rotate. The driving impeller 72 is sleeved on the upper glass sheet 51 and is vertically misaligned with the rotary bearing 71. A plurality of blades are formed at the outer edge of the driving impeller 72 at intervals, and the blades are driven by the airflow in the cooling air pipe 41.
[0046] Refer to Figure 1 , 2, the cooling air pipe 41 is fixedly inclined at the position corresponding to the side wall of the positioning bracket 3. The cooling air pipe 41 penetrates through the positioning bracket 3 at the position corresponding to the driving impeller 72 and forms an air flow in the horizontal direction. The thin channel structure 5 further includes an air inlet 52 and an air outlet 53 for connecting the cooling air pipe 41 to the inside of the cooling cavity 8. The air inlet 52 is horizontally spaced and opened on the side wall of the positioning ring 101 and communicates with both the inside and outside of the positioning ring 101. The air inlet end of the cooling structure 4 penetrates through the side wall of the positioning bracket 3 and communicates with the air inlet 52. The cooling air duct 42 is opened on the positioning bracket 3. The blades of the driving impeller 72 corresponding to the air inlet 52 are accommodated in the cooling air duct 42, and the bottom surface of the cooling air duct 42 extends obliquely downward and communicates with the air inlet 52. Thus, the driving impeller 72 and the air inlet duct at the vertical dislocation can be simultaneously affected by the cooling air pipe 41. The gas in the cooling air pipe 41 acts horizontally and drives the driving impeller 72 to rotate. Then, it enters the cooling cavity 8 through the air inlet 52 and continuously cools the lower-layer glass flakes 51 below.
[0047] Refer to Figure 3 , 9 , the air outlet 53 is horizontally spaced and opened on the side wall of the positioning ring 101 and communicates with both the inside and outside of the positioning ring 101. An exhaust structure 12 is provided at the position of the positioning bracket 3 corresponding to the air outlet 53. The exhaust structure 12 includes an exhaust passage 121 and an exhaust air pipe 122. The exhaust passage 121 is opened at the position of the positioning bracket 3 corresponding to the air outlet 53. The exhaust air pipe 122 communicates with the exhaust passage 121 and extends along the operating cantilever 1 and communicates with the atmosphere. Thus, the exhaust end of the exhaust air pipe 122 is far from the laser emission module 2, avoiding the influence of the laser effect caused by the condensation water and water mist generated by the contact of the cold air with the air.
[0048] Refer to Figure 2 , further, the air inlet 52 and the air outlet 53 are arranged on the side wall of the positioning ring 101 in opposite directions and on the same side, and the air inlet 52 and the air outlet 53 are respectively tangent to the outer side wall of the cooling cavity 8. And the exhaust air pipe 122 and the cooling air pipe 41 are close to each other and fixed, so that the exhaust air pipe 122 and the cooling air pipe 41 are located on the same side of the laser emission module 2, preventing the trachea from affecting the line of sight. At the same time, the direction of the air inlet 52 can be set to be the same as the rotation direction of the driving impeller 72, so that the upper-layer rotating glass flakes 51 and the air flow directions of the air inlet 52 and the air outlet 53 are the same, making the air flow more smooth.
[0049] Refer to Figure 2 , 3 , through the isolation of the cooling gas and the air during the cooling process, it is avoided that the cooling gas contacts the air to generate condensation water and water mist, resulting in poor effects such as scattering or refraction of the laser.
[0050] Refer to Figure 3, Further, a plurality of vertically communicating carbon dioxide discharge holes 6 are provided on the surface of the lower glass sheet 51. When the lower glass sheet 51 abuts against the skin, the carbon dioxide discharge holes 6 are sealed to prevent the generation of water mist. When the instrument is separated from the skin, carbon dioxide is discharged and has stability, filling the gap during separation, thereby isolating air to a certain extent and preventing the skin after laser treatment from being oxidized, making the treatment effect better.
[0051] Another embodiment of the present application discloses a beauty operation method of a laser beauty instrument: S1: A sufficient amount of dry ice is placed in the sealed box 111, and the heating wire 113 is started to accelerate the sublimation of dry ice into carbon dioxide gas, thereby generating a sufficient amount of carbon dioxide cooling gas without moisture. The cooling gas enters the cooling air duct 42 and is conveyed to the laser emission module 2.
[0052] S2: The positioning bracket 3 installed with the glass sheet 51 is moved to the skin to be beautified. The gas in the cooling air pipe 41 drives the blades to rotate horizontally by the action of the cooling air duct 42, ensuring that there is no condensed water on the surface of the upper glass sheet 51. Then, it enters the cooling cavity 8 from the air inlet 52, thereby generating a cooling effect on the lower glass sheet 51, cooling the skin surface to be beautified, and preventing the skin surface from being damaged under the action of the laser.
[0053] S3: After the laser treatment is completed, the positioning bracket 3 is lifted, and the carbon dioxide discharge holes 6 on the lower glass sheet 51 release carbon dioxide to protect the just-treated skin from oxidation.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
