Description

Technical Field

[0001] The present invention relates to the technical field of laser therapeutic apparatus, and more specifically, to a laser therapeutic apparatus with a cold compress function. Background Art

[0002] Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength, energy, and pulse width, the laser can pass through the surface of the skin to reach the hair follicles at the root of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thereby making the hair lose its regeneration ability, while not damaging the surrounding tissues, and the pain is mild. Laser hair removal utilizes the "selective photothermal effect" of the laser, using lasers adjusted to a specific wavelength to pass through the epidermis and directly irradiate the hair follicles. The melanin in the hair follicles and hair shafts selectively absorbs light energy, and the resulting thermal effect causes the hair follicles to necrotize and the hair to fall off, thereby achieving the purpose of hair removal; however, after the light is absorbed at the operating site, the skin will feel burning and painful due to photothermal and photochemical effects, which makes the user feel uncomfortable. To solve this problem, it is necessary to apply cold compresses to the operating part in time to reduce the burning and pain sensations of the user. At the same time, a laser is a device that uses the direct transition of atoms, ions, or molecules in the laser medium to radiate coherent light for amplification. During the operation of the laser, due to the large amount of energy accumulation and high-power output, the laser will generate a lot of heat. In order to ensure the stable operation and prolong the life of the laser, the laser needs to be cooled. Therefore, how to make the laser achieve the effect of cooling the skin is a technical problem to be solved by the present invention. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0033] like Figure 1-Figure 12 As shown, the present invention provides a laser therapy device with a cold compress function, comprising: a handpiece 1 provided with a light exit window 5 and a base, the handpiece 1 and the base are connected by a wire, the handpiece 1 is composed of a laser component 2 provided with a refrigeration component, a handpiece shell 3 and a first control component 4, the laser component 2 and the first control component 4 are both arranged in the handpiece shell 3, the first control component 4 is electrically connected to the base through a wire, the laser component 2 is electrically connected to the first control component 4, the refrigeration component is used to cool the laser component 2 and achieve a cold compress effect through the light exit window 5.

[0034] Through the design of the above structure, the refrigeration component will cool the laser component 2. At the same time, the laser component 2 can contact the skin through the light outlet window 5, providing the user with a cool touch, thereby achieving the effect of cooling the skin. At the same time, the separate design of the handpiece and the base only needs to consider how to improve the heat dissipation efficiency of the handpiece housing 3, and there will be no problems of high heat generation and low heat dissipation efficiency of the all-in-one machine.

[0035] The base is composed of a base shell 6, a power control component, a second control component, an emergency stop switch 7, a key switch 8 and an interlock switch 9. The base shell 6 is provided with a power jack 10 for connecting to the mains. The power jack 10 is electrically connected to the power control component, and the power control component is electrically connected to the first control component 4 through the second control component. The laser assembly 2 is composed of a laser 11, a laser radiator 12, a refrigeration component, a cooling fan 13, and a light guide component. The laser 11 is fixed and pressed against the first fixing plate 15 of the laser radiator 12 through a laser bracket 14. The cooling fan 13 is arranged on a fan bracket 16 and connected to the laser bracket 14 through the fan bracket 16. The air outlet of the cooling fan 13 faces the fins of the laser radiator 12. The laser radiator 12 is located between the laser bracket 14 and the fan bracket 16. The laser bracket 14 and the fan bracket 16 clamp and fix the laser radiator 12. The light guide component is arranged on the laser bracket 14, and the refrigeration component is arranged on the laser bracket 14 and connected to the light guide component to cool the light guide component. The light guide assembly is composed of a light guide crystal 17, a window sheet 18 and a window sheet fixing part 19. The window sheet 18 is bonded to one end of the light guide crystal 17. The light guide crystal 17 is arranged in the window sheet fixing part 19 and connected to the laser bracket 14 through the window sheet fixing part 19. One light guide surface of the light guide crystal 17 faces the light outlet of the laser 11, and the other surface provided with the window sheet 18 faces the light outlet window 5. The window sheet 18 is located in the light outlet window 5. The refrigeration assembly is composed of a refrigeration radiator 20 and a refrigeration sheet 21. A first hole for installing the refrigeration sheet 21 is provided on the laser bracket 14. The refrigeration sheet 21 is located in the first hole, and the cold surface of the refrigeration sheet 21 is in close contact with the window sheet fixing part 19, and the hot surface is in close contact with the second fixing plate 22 of the refrigeration radiator 20. The refrigeration radiator 20 is connected to the laser bracket 14 through the second fixing plate 22, and the refrigeration sheet 21 is pressed tightly. The cooling sheet 21 cools the window sheet 18 through the window sheet fixing member 19 to achieve a cold compress effect. The fins of the cooling radiator 20 are arranged parallel to or normally to the fins of the laser radiator 12 to reduce the resistance of wind flow.

[0036] The second fixing plate 22 is connected to the hot surface of the cooling fin 21 . The heat pipe 23 is disposed on the top of the second fixing plate 22 and is connected to the hot surface of the cooling fin 21 through the second fixing plate 22 .

[0037] The handpiece 1 has a dual air path structure. The wind direction can be changed by installing the cooling fan 13 in reverse. The handpiece housing 3 is provided with three air outlets. The first air outlet is opposite to the cooling fan 13, and the second and third air outlets are opposite to the gap between the fins of the laser radiator 12. Because the cooling radiator 20 is located on one side of the laser radiator 12, the side provided with the cooling radiator 20 is the second air outlet, and the side without the cooling radiator 20 is the third air outlet.

[0038] First air path: under the action of the cooling fan 13, the wind enters the therapeutic device through the first air port of the handpiece housing 3, then enters the air inlet of the cooling fan 13, and then blows into the laser radiator 12 through the air outlet of the cooling fan 13; after that, part of the wind passes through the cooling radiator 20, and then the heat generated by the laser 11 and the heat generated by the cooling sheet 21 are discharged from the therapeutic device through the second air port, and the other part of the wind directly discharges the heat generated by the laser 11 out of the therapeutic device through the second air port; if the cooling fan 13 is installed in reverse, the wind passes through the cooling fan 13 under the action of the cooling fan 13 The second air port of the handpiece housing 3 enters the therapeutic apparatus, and then a part of the air passes through the cooling radiator 20, enters the laser radiator 12, and then enters the air inlet of the cooling fan 13, and then blows out of the first air port of the handpiece housing 3 through the air outlet of the cooling fan 13, so that the heat generated by the laser 11 is discharged from the therapeutic apparatus; another part of the air directly enters the laser radiator 12, and then enters the air inlet of the cooling fan 13, and then blows out of the first air port of the handpiece housing 3 through the air outlet of the cooling fan 13, so that the heat generated by the laser 11 is discharged from the therapeutic apparatus;

[0039] Second air path: under the action of the cooling fan 13, the wind enters the therapeutic instrument through the first air port of the handpiece housing 3, then enters the air inlet of the cooling fan 13, is blown into the laser radiator 12 through the air outlet of the cooling fan 13, and is blown out of the instrument through the third air port, so that the heat generated by the laser 11 is discharged out of the therapeutic instrument; if the cooling fan 13 is installed in reverse, the wind enters the therapeutic instrument through the third air port of the handpiece housing 3 under the action of the cooling fan 13, passes through the laser radiator and enters the air inlet of the cooling fan 13, and is blown out of the first air port of the handpiece housing 3 through the air outlet of the cooling fan 13, so that the heat generated by the laser 11 is discharged out of the therapeutic instrument.

[0040] The laser 11 and the cooling plate 21 in the laser assembly 2 generate heat; the heat generated by the laser 11 is transferred to the first fixing plate 15, and then transferred to the heat pipe and the fins. The function of the heat pipe is to transfer the heat to the fins faster to avoid the heat accumulation on the first fixing plate 15. Through the design of the above structure, the handpiece 1 is provided with a double air path structure consisting of a first air path and a second air path. The first air path and the second air path dissipate the heat generated by the laser 11 and the cooling plate 21 in the laser assembly 2. Figure 6 shown.

[0041] In the previous embodiment, we place the cold surface of the refrigeration plate 21 of the refrigeration assembly close to the window plate fixing member 19, and the hot surface close to the second fixing plate 22 of the refrigeration radiator 20, and the heat pipe 23 is arranged on the top of the second fixing plate 22, and is connected to the hot surface of the refrigeration plate 21 through the second fixing plate 22. However, the second fixing plate 22 is usually used as a structure for fixing the refrigeration plate 21, and the main heat transfer is still completed by the heat pipe 23. Therefore, the second fixing plate 22 must be strong and durable, low in cost, and also have good thermal conductivity to avoid heat accumulation in the second fixing plate 22. Therefore, the selectable manufacturing materials are very limited, and it is more difficult to control the cost. Because the second fixing plate 22 is arranged between the heat pipe 23 and the refrigeration plate 21, the heat transfer efficiency is also reduced. For this reason, we provide another implementation method, that is, directly connecting the heat pipe 23 to the refrigeration plate 21 to improve the efficiency of heat transfer, and the second fixing plate 22 is only used as a structure for fixing the heat pipe 23 and the refrigeration plate 21. In this embodiment, a second hole with a thread and a heat-conducting member threadedly connected to the second hole through a first connecting member 24 are provided on the laser bracket 14. The second hole is located on one side of the first hole to avoid affecting the placement of the cooling plate 21. At least four third holes with internal threads are provided on the window plate fixing member 19. The third holes are all located within the opening range of the first hole. The heat-conducting member extends into the first hole and is tightly attached to the cooling plate 21. The portion of the heat-conducting member located in the first hole is threadedly connected to the third hole through a second connecting member 25. As a result, one end of the heat-conducting member is connected to the laser bracket 14 to achieve fixation between itself and the laser bracket 14, and the other end extends into the first hole and is connected to the window plate fixing member 19 to achieve connection and fixation between itself and the window plate fixing member 19. Compared with the aforementioned embodiment, this arrangement method increases the connection between the window plate fixing member 19 and the laser bracket 14 through the heat-conducting member, making the overall structure more stable. The heat pipe 23 is tightly attached to the heat conductive member and selectively tightly attached to the hot surface of the refrigeration plate 21. Depending on the material and shape of the heat pipe 23, the implementation method of the heat conductive member is different. Some heat pipes 23 can be directly attached to the refrigeration plate 21, while some heat pipes 23 need to be attached to the refrigeration plate 21 through the heat conductive member. See the following implementation methods for details. The second fixing plate 22 is detachably connected to the heat conductive member through the second connecting member 25, and presses the heat pipe 23. Therefore, the function of the second fixing plate 22 is changed from pressing the refrigeration plate 21 and transferring heat to the heat pipe 23 in the aforementioned embodiment to being used only to fix the heat pipe 23. Therefore, the material selection of the second fixing plate 22 can be more flexible and is no longer limited to materials with strong thermal conductivity. The production cost and production process of the second fixing plate 22 can be reduced and optimized.

[0042] In the first embodiment, the heat conducting member is in a "Y" shape, and is composed of a body fixing end 26 connected to the second hole of the laser bracket 14, and two heat pipe fixing ends 27 symmetrically arranged. Figure 8 , 9 As shown, the body fixed end 26 is provided with a first strip hole 28 and a limit bar 29, the limit bar 29 is located outside the first strip hole 28 and located on the side where the body fixed end 26 is connected to the laser bracket 14, as shown in FIG. Fig. 9 As shown, a sliding gasket 30 is provided on the limiting strip 29. When the first connecting member 24 is connected to the second hole, the sliding gasket 30 can slide on the limiting strip 29 to adjust the position. The first connecting member 24 is provided in the first strip hole 28. The first connecting member 24 passes through the first strip hole 28 and the sliding gasket 30, and is threadedly connected to the second hole. The first strip hole 28 can enable the heat conductive member to adjust its position at any time when the first connecting member 24 is installed. A strip groove 31 is provided on the side of the heat pipe fixing end 27 away from the window sheet fixing member 19, and a second strip hole 33 is provided on the inner bottom of the strip groove 31. At least two support columns 32 adapted to the position of the third hole are provided on the side of the heat pipe fixing end 27 close to the window sheet fixing member 19, and the support columns 32 are provided with a strip groove 31 adapted to the position of the third hole. The fourth hole is connected, and the position and shape of the fourth hole are adapted to the third hole. The second connector 25 passes through the second strip hole 33. According to the use requirements, the second fixing plate 22 can be directly connected to the heat-conducting member through the second connector 25. For example, the second connector is a combination of a screw and a nut. The screw passes through the second fixing plate 22 and the second strip hole 33. After adjusting the installation position of the second fixing plate 22, the nut is directly screwed on, so that the nut is pressed against one side of the mounting support column 32 of the heat pipe fixed end 27, and then another screw is used to pass through the fourth hole and threadedly connected to the third hole to achieve the connection between the heat-conducting member and the window sheet fixing member 19. Usually, the above connection method is mostly caused by the fact that the installation hole on the second fixing plate 22 and the fourth hole are not opposite to each other, and the second fixing plate 22 needs to be connected to the heat-conducting member, and the heat-conducting member is connected to the window sheet fixing member 19. Under normal circumstances, the second connector 25 can directly pass through the fourth hole and be threadedly connected to the third hole. By setting the second strip hole 33, the size and shape of the second fixing plate 22 are not restricted, and can be connected to the heat pipe fixed end 27. The heat pipe 23 used in this embodiment is mostly as follows Figure 7 The flat shape shown in FIG. 1 has a larger contact area. Figure 4 , 5 When the circular tube is used as shown in the figure, the contact area between the circular tube and the cooling fin 21 is small. In this case, the heat conducting member mentioned in this embodiment cannot be used. Therefore, a second embodiment of the heat conducting member is provided.

[0043] In the second embodiment, the heat conducting member is composed of a fitting member 34 which is in close contact with the hot surface of the cooling plate 21, and four inclined members 35 provided with fifth holes, such as Fig.10As shown, at least four third strip holes 36 are provided on the fitting member 34. The fitting member 34 is usually rectangular. The four third strip holes 36 are located on the diagonal lines of the fitting member 34. The third hole is located within the opening range of the third strip hole 36, so that the second connecting member 25 can be connected to the third hole through the third strip hole 36, and the position of the inclined member 35 is adjusted. The second connecting member 25 passes through the second fixing plate 22, the fifth hole, and the third strip hole 36 in sequence and is connected to the third hole. Because the heat pipe 23 is usually made of copper or other materials, when installing, such as Fig.11 , 12 As shown, the second connecting member 25 is first passed through the second fixing plate 22, then through the fifth hole of the inclined member 35, and then through the third strip hole 36. Then, the fitting member 34 is placed on the cooling plate 21, and the second connecting member 25 is threadedly connected with the third hole of the window plate fixing member 19. As the second fixing plate 22 is pressed down, the heat pipe 23 is deformed by compression and fits on the inclined member 35. Because the high point of the inclined member 35 is located at the four corners of the fitting member 34, and the low point of the inclined member 35 is located at the center of the fitting member 34, when the heat pipe 23 is deformed by compression, a "wedge" will be formed between the four inclined members 35, thereby preventing the heat pipe 23 from detaching. At the same time, in this embodiment, the first connecting member 24 can be omitted from the heat conducting member, because the cooling plate 21 is located in the first hole, so the laser bracket 14 and the window plate fixing member 19 can be fixed only by the second connecting member 25.
