[0002] Red and yellow devices are primarily used for skin treatment and beauty. Red and yellow devices, particularly red, yellow, and blue light therapy devices, utilize specific wavelengths of red and yellow light to provide targeted treatment for skin problems. Red light (bioactive light) has a wavelength of approximately 633nm and has the potential to increase cell activity, promote cell metabolism, deeply repair, combat inflammation, and improve acne scars and pigmentation. It is suitable for skin conditions such as acne, herpes zoster, skin infections, seborrheic dermatitis, and psoriasis. Yellow light (wavelength approximately 590nm) is used to inhibit hyperreactivity of vascular nerves, improve skin tolerance, repair the skin barrier, and has a certain whitening effect, making it particularly suitable for people with sensitive skin and those suffering from rosacea.

[0003] Existing therapeutic device lights generally have a light shield set on the irradiation lamp to prevent excess light from shining on medical staff and causing harm. However, in actual use, depending on the size of the treatment area, a specific area needs to be irradiated. At this time, it is necessary to replace the light shields of different sizes for use. Each replacement is very inconvenient. Therefore, in response to the above-mentioned problem, a light shield that can adjust the size of the irradiation area is designed. Utility Model Content

[0032] Red and yellow devices are primarily used for skin treatment and beauty. Red and yellow devices, particularly red, yellow, and blue light therapy devices, utilize specific wavelengths of red and yellow light to provide targeted treatment for skin problems. Red light (bioactive light) has a wavelength of approximately 633nm and has the potential to increase cell activity, promote cell metabolism, deeply repair, combat inflammation, and improve acne scars and pigmentation. It is suitable for skin conditions such as acne, herpes zoster, skin infections, seborrheic dermatitis, and psoriasis. Yellow light (wavelength approximately 590nm) is used to inhibit hyperreactivity of vascular nerves, improve skin tolerance, repair the skin barrier, and has a certain whitening effect, making it particularly suitable for people with sensitive skin and those suffering from rosacea.

[0033] In the related art, a light shield is generally provided on the therapeutic device lamp to prevent excess light from shining on medical staff and causing harm. However, in actual use, depending on the size of the treatment area, a specific area needs to be irradiated. At this time, it is necessary to replace the light shield of different sizes for use, which is very inconvenient each time.

[0034] To address the problems in the related art to a certain extent, the present invention provides a light shielding device for a therapeutic device. When the illumination area of ​​the irradiation lamp 12 needs to be adjusted, the tube body 28 can be rotated so that the gear ring 24 engages with the gear 23 during rotation, driving the gear 23 to rotate, causing the threaded rod 22 to rotate, driving the ring body 1 21 to move up and down. When the ring body 1 21 moves downward, it pushes the rotating rod 26 through the connecting rod 25, causing the bottom end of the rotating rod 26 to spread out, and at the same time, the elastic light shielding cloth 27 is stretched, thereby expanding the illumination range of the irradiation lamp 12. When the ring body 1 21 moves upward, the connecting rod 25 pulls the rotating rod 26 to rotate, causing the bottom end of the rotating rod 26 to move closer, causing the elastic light shielding cloth 27 to contract, thereby reducing the illumination range of the irradiation lamp 12. The light shield 13 can then be aligned with the area of ​​the patient to be irradiated for irradiation. After adjustment is completed, the ring body 2 32 can be pushed downward so that the insertion rod 34 is inserted into the positioning hole 32 at the top of the tube body 28, thereby preventing the tube body 28 from rotating, thereby stabilizing the position of the ring body 1 21.

[0035] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0036] Combine Figure 1-Figure 5 The embodiment of the present application provides a light-shielding device for a therapeutic device, comprising: a therapeutic device body 11, on the top connecting arm of which an irradiation lamp 12 is provided; a light shield 13 is provided on the outer wall of the irradiation lamp 12; an adjustment component 2 is provided inside the light shield 13, and the adjustment component 2 comprises: a ring body 21, which is provided inside the light shield 13; a threaded rod 22 whose top end passes through the ring body 21 and the inner wall of the light shield 13, and is threadedly connected to the ring body 21 and rotates with the light shield 13 connection; a gear 23 is arranged at the top of the threaded rod 22; a gear ring 24 is sleeved on the outside of the irradiation lamp 12 and meshes with the gear 23; a connecting rod 25 is arranged inside the light shield 13, and one end is rotatably connected to the outer wall of the ring body 21; one end of the rotating rod 26 is rotatably connected to the inner wall of the light shield 13, and the top is rotatably connected to the bottom end of the connecting rod 25; an elastic light-shielding cloth 27 is arranged inside the light shield 13, and both sides are connected to the rotating rod 26.

[0037] Specifically, the therapeutic device body 11 is a red-yellow instrument, model 5050, a four-in-one medical beauty lamp bead spectrometer, beauty and physical therapy instrument, and lamp bead red, yellow, and blue light therapy device. Its principle is to stimulate ATP production and increase natural skin cell activity by stimulating the production of 630±10nm wavelengths of light absorbed by mitochondria in cells. This can promote the synthesis of fibroblast growth factor and fibroblasts and keratin in the dermis, accelerate the regeneration of new skin tissue, shorten the recovery period, and reduce the formation of acne scars. The elastic blackout fabric 27 is a black stretch fabric with elastic properties that can be stretched and retracted. The black setting can also block light.

[0038] During use, when it is necessary to adjust the size of the illumination area of ​​the irradiation lamp 12, the gear ring 24 can be rotated so that the gear ring 24 engages with the gear 23 during rotation, driving the gear 23 to rotate, causing the threaded rod 22 to rotate, driving the ring body 21 to move up and down, and when the ring body 21 moves downward, it will push the rotating rod 26 through the connecting rod 25, so that the bottom end of the rotating rod 26 spreads out, and the elastic light-shielding cloth 27 is stretched at the same time, which can expand the illumination range of the irradiation lamp 12. When the ring body 21 moves upward, the connecting rod 25 pulls the rotating rod 26 to rotate, so that the bottom end of the rotating rod 26 is close, causing the elastic light-shielding cloth 27 to shrink, which can reduce the illumination range of the irradiation lamp 12, and then the light shield 13 is aligned with the area that the patient needs to irradiate for irradiation.

[0039] In some embodiments, the adjustment assembly 2 further includes: a stopper 221 disposed at the bottom of the threaded rod 22 .

[0040] During use, the setting of the stopper 221 can prevent the ring body 21 and the threaded rod 22 from being separated while the threaded rod 22 rotates.

[0041] In some embodiments, the adjustment assembly 2 further includes: a tube 28 sleeved on the outer wall of the irradiation lamp 12 , and the outer wall of the tube 28 is fixedly connected to the inner wall of the gear ring 24 .

[0042] The arrangement of the tube body 28 during use makes it easy to grip and more comfortable to grip, and can also drive the gear ring 24 to mesh with the gear 23 .

[0043] In some embodiments, the adjustment assembly 2 further includes: an anti-slip strip 281 provided on the outer side wall of the tube body 28 .

[0044] During use, the friction force can be increased when the grip tube 28 is rotated, making it less likely to slip and more convenient to rotate.

[0045] In some embodiments, the adjustment component 2 further includes a sponge ring 29 disposed at the bottom of the light shield 13 .

[0046] The provision of the sponge ring 29 during use can make the bottom of the light shield 13 softer when in contact with the skin, making it more comfortable to use.

[0047] In some embodiments, a fixing assembly 3 is provided on the tube body 28, and the fixing assembly 3 includes: a convex strip 31 provided on the outer wall of the irradiation lamp 12; a second ring body 32 slides on the outer wall of the irradiation lamp 12 and is restricted by the convex strip 31 and cannot rotate; a positioning hole 33 is opened at the top of the tube body 28; an insertion rod 34 is provided at the bottom of the second ring body 32, and the bottom end is inserted into the interior of the positioning hole 33.

[0048] When in use, after adjustment is completed, the ring body 2 32 can be pushed downward so that the insertion rod 34 is inserted into the positioning hole 32 at the top of the tube body 28 to restrict the tube body 28 from rotating, thereby stabilizing the position of the ring body 1 21 .

[0049] In some embodiments, the positioning hole 33 and the insertion rod 34 are designed to be spaced one millimeter apart.

[0050] The dense arrangement of the positioning holes 33 and the insertion rods 34 during use can reduce the error during fixation, making it easier to fix the tube body 28.

[0051] In some embodiments, the fixing assembly 3 further includes: a cone 35 correspondingly disposed at the bottom of the insertion rod 34 .

[0052] The pointed tip at the bottom of the cone 35 makes it easier to insert into the positioning hole 33 during use.

[0053] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0054] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
