Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to an infrared therapy lamp head. Background Technology

[0002] Infrared therapy devices are medical treatment equipment that emits infrared rays of specific wavelengths to irradiate parts of the human body, promoting local blood circulation, relieving muscle soreness, accelerating tissue repair, and improving joint stiffness. Existing infrared therapy devices typically use a fixed single-lamp or multi-lamp combination structure, with the lamp head fixed to a bracket. The irradiation direction is changed by manually adjusting the bracket angle or by the user moving their limb. This design has the following disadvantages: First, the irradiation range of the lamp head cannot be adjusted, meaning the length of the infrared coverage area cannot be adjusted according to the treatment area, resulting in either an excessively large irradiation area wasting energy or an insufficiently small area failing to provide complete coverage. Second, adjustment is inconvenient; when irradiating the arm, it is difficult to cover the lower part of the arm, requiring the user to constantly change posture to achieve irradiation around the limb. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide an infrared therapy lamp head that, by comprising a housing, a bracket, and a lamp holder, allows the lamp holder to rotate around the bracket, thereby enabling circumferential irradiation therapy on the limbs, making it convenient to use.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an infrared therapy lamp head, comprising: The outer casing has two opposing positioning holes. The bracket is located inside the outer shell, with its two ends connected to two positioning holes respectively. The bracket has a light-transmitting hole, and an installation cavity is provided between the bracket and the inner wall of the outer shell. The ring frame is rotatably installed in the mounting cavity, with the bracket located inside the ring frame; A lamp holder is fixed on a ring frame, and a movable platform is slidably mounted on the lamp holder. Two parallel lamp bodies are set on the movable platform, with the axial direction of the lamp body, the length direction of the lamp holder, and the length direction of the bracket parallel to each other; The lamp body is used to emit infrared rays. The two lamp bodies are controlled by an adjustment mechanism to change the length of the infrared ray coverage area. The infrared rays are irradiated into the bracket through the light-transmitting hole.

[0005] Preferably, the lamp holder has two parallel through slots, and a lamp holder is slidably installed in the through slots. The two lamp bodies are respectively installed on the two lamp holders. The movable platform is connected to the two lamp holders through an adjustment mechanism. When the movable platform moves, it drives the two lamp holders to move synchronously in the through slots.

[0006] Preferably, the adjustment mechanism includes a drive shaft and a driven shaft, both of which are rotatably mounted on a movable platform. A first motor for driving the drive shaft to rotate is fixed on the movable platform. A first gear and a synchronous pulley are fixed on both the drive shaft and the driven shaft. A synchronous belt is wound around the two synchronous pulleys. A rack is fixed on each of the two lamp holders, and the two racks mesh with the two first gears respectively.

[0007] Preferably, the lamp holder includes a mounting plate and a condenser fixed to the mounting plate near the bracket, the through groove passes through the mounting plate and the condenser, and the two lamp bodies are located on the side of the condenser facing the bracket.

[0008] Preferably, two annular plates are fixed inside the mounting cavity, and limit rings are fixed on the opposite side walls of the two annular plates. Each of the two limit rings is provided with a limit conical surface. There are two annular frames in total, and the two annular frames are fixedly connected by a connecting rod and a lamp holder. Each of the opposite end faces of the two annular frames is provided with a positioning conical surface that mates with the two limit conical surfaces. Rollers are provided between the positioning conical surface and the limit conical surface.

[0009] Preferably, a second motor is fixedly mounted on one of the annular plates, and toothed grooves are formed on the annular frame near the second motor. A second gear that meshes with the toothed grooves is connected to the output shaft of the second motor.

[0010] Preferably, a cooling fan is fixed at one end of the lamp holder, which is used to cool the lamp holder and the adjustment mechanism. Corresponding ventilation holes are provided at both ends of the outer shell, and multiple heat dissipation fins are fixed on the circumferential outer wall of the outer shell.

[0011] Preferably, a connecting arm is hinged to the outer casing, and the connecting arm is connected to an external support.

[0012] Preferably, a plurality of parallel rollers are rotatably mounted on the lower part of the bracket, with a light-transmitting gap between two adjacent rollers, and massage textures are provided on the rollers.

[0013] Preferably, a third motor and a guide rail are fixed on the lamp holder, the movable platform is slidably mounted on the guide rail, a nut seat is fixed on the movable platform, and a screw that is threadedly engaged with the nut seat is rotatably mounted on the lamp holder. The third motor is used to drive the screw to rotate.

[0014] The beneficial effects of this invention are as follows: The lamp head designed in this invention has a cylindrical outer shell with an internal bracket. The user can place their limb on the bracket, at which point the shell surrounds the user's limb. The two lamp bodies that emit infrared rays are axially displaced by an adjustment mechanism, which allows the overall length of the light-emitting unit composed of the two lamp bodies to be changed. As the movable platform slides on the lamp holder, the light-emitting unit can also be axially displaced as a whole. The lamp holder can also rotate as the ring frame rotates within the outer shell. The user only needs to maintain a fixed posture, and the position of the lamp body can be adjusted by moving the movable platform on the lamp holder and rotating the ring frame, allowing for infrared therapy to a fixed location on a specific part of the limb. When the ring frame continuously rotates, it can also provide 360-degree infrared therapy around the user's limb. Furthermore, changing the axial position of the two lamp bodies can adjust the overall irradiation length range of the light-emitting unit, thereby making the treatment location more precise.

[0015] The present invention has a corresponding heat dissipation structure to reduce the temperature of the outer shell and internal structure. The cooling fan is set at one end of the lamp holder, and the two ends of the outer shell have ventilation holes. The cooling fan can drive the outside air into the outer shell to cool the lamp holder and lamp body. The hot air is discharged from the ventilation hole on the other side. At the same time, heat dissipation fins are set on the outer shell for passive heat dissipation to ensure that the temperature of the lamp head is within an appropriate range.

[0016] This invention incorporates rollers within the support frame, making it easier for users to move their limbs. Light-transmitting gaps are reserved between the rollers to reduce the obstruction of infrared rays. Additionally, massage patterns are provided on the rollers, allowing users to move their limbs back and forth autonomously during infrared therapy for auxiliary massage, thereby enhancing the therapeutic effect.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: like Figures 1 to 8 As shown, Embodiment 1 of the present invention provides an infrared therapy lamp head. The lamp head has an outer shell 1 with an overall cylindrical structure. Two opposing positioning holes are symmetrically opened at the front and rear ends of the outer shell 1 to provide stable axial positioning. The bracket 2 is located at the center of the inner side of the outer shell 1. The edges of the two positioning holes are provided with inner grooves. The two ends of the bracket 2 respectively abut against the inner grooves of the two positioning holes, thereby firmly fixing the bracket 2 inside the outer shell 1 and preventing shaking or displacement during use.

[0029] The bracket 2 is also cylindrical in shape. Multiple evenly distributed, penetrating light-transmitting holes 3 are provided on the side wall of the bracket 2 to ensure that infrared rays can pass through the light-transmitting holes 3 and irradiate the interior of the bracket 2, facilitating treatment of the limb placed on the bracket 2. An annular mounting cavity 4 is formed between the bracket 2 and the inner wall of the outer shell 1 to facilitate the installation of structures such as the lamp body 8 and the lamp holder 6.

[0030] like Figure 3 As shown, two annular frames 5 are rotatably mounted inside the mounting cavity 4, with the bracket 2 located inside the annular frames 5, allowing the annular frames 5 to rotate 360 ​​degrees around the axis of the bracket 2. The two ends of the lamp holder 6 are fixed to the two annular frames 5 respectively, and can rotate synchronously with the annular frames 5, thus changing the illumination angle of the lamp body 8 on the lamp holder 6. A third motor 30 is fixed to one end of the lamp holder 6, and a guide rail 31 is fixed to the lamp holder 6, with a movable platform 7 slidably mounted on the guide rail 31. A screw 33 is rotatably mounted on the lamp holder 6 via a bearing seat, and a nut seat 32 is fixed to the movable platform 7, forming a threaded engagement with the screw 33. When the third motor 30 drives the screw 33 to rotate, the rotational motion is converted into linear motion of the movable platform 7 along the length of the lamp holder 6 via the nut seat 32, thereby changing the position of the lamp body 8 along the axial direction of the bracket 2.

[0031] Two parallel lamps 8 are mounted on the movable platform 7. Each lamp 8 is an infrared emitter capable of stably emitting a therapeutic infrared beam of a specific wavelength. The axial direction of each lamp 8 is parallel to the length direction of the lamp holder 6 and the bracket 2. The two lamps 8 form a single light-emitting unit. The axial displacement of each lamp 8 is controlled by an adjustment mechanism mounted on the movable platform 7, thereby changing the axial length of the light-emitting unit and dynamically adjusting the overall length of the infrared coverage area. Infrared rays are emitted through the light-transmitting holes 3 of the bracket 2 and directly act on the user's limbs.

[0032] With the above configuration, the outer shell 1 acts as a surrounding protective shell, allowing the user to naturally place the limb flat on the support 2. The outer shell 1 completely surrounds the limb, providing safe protection and a stable treatment environment, while also preventing the user's eyes from directly looking at the lamp body 8. The rotatable ring frame 5 allows the lamp holder 6 and the lamp body 8 to rotate around the limb at multiple angles, achieving all-round irradiation coverage of the limb. The movable platform 7 slides along the straight line of the lamp holder 6, allowing the light-emitting unit composed of the two lamp bodies 8 to move as a whole along the axial direction, thereby flexibly adjusting the irradiation position and achieving targeted infrared treatment of a fixed local area of ​​the limb. The adjustment mechanism changes the axial length of the light-emitting unit, which can precisely control the length range of the infrared irradiation area to adapt to the needs of treatment sites of different sizes.

[0033] Users only need to maintain a fixed posture to complete the comprehensive adjustment of the position of the lamp body 8 by rotating the ring frame 5 and sliding the movable platform 7. This enables precise local treatment as well as 360-degree surround infrared treatment while the ring frame 5 is continuously rotating. At the same time, by adjusting the interval between the two lamp bodies 8, the treatment area can be adapted to different sizes, making the treatment position more accurate and efficient.

[0034] Example 2: Based on Embodiment 1, Embodiment 2 specifically designs an adjustment mechanism and a rotation support and drive structure for the ring frame 5.

[0035] like Figure 3 and Figure 8 As shown, the lamp holder 6 comprises a mounting plate 17 and a condenser 18. The condenser 18 is fixed to the side of the mounting plate 17 near the bracket 2. The inner wall of the condenser 18 is made of a high-reflectivity material, which can effectively concentrate the infrared beam emitted by the lamp body 8, improve the illumination intensity and focusing accuracy, and reduce energy loss. Two parallel through slots 9 are formed on the mounting plate 17 and the condenser 18, which pass through the mounting plate 17 and the condenser 18. Lamp holders 10 are slidably installed in both through slots 9, and the two lamp bodies 8 are respectively and securely installed on the two lamp holders 10. The lamp body 8 is located on the side of the condenser 18 facing the bracket 2, so that the condenser 18 can concentrate and guide the infrared light emitted by the lamp body 8 towards the bracket 2.

[0036] The movable platform 7 is connected to two lamp holders 10 via an adjustment mechanism. When the movable platform 7 moves, it can drive the two lamp holders 10 to move synchronously and in the same direction within the through groove 9. Figure 5 As shown, the adjustment mechanism includes a drive shaft and a driven shaft 11. Both the drive shaft and the driven shaft 11 are rotatably mounted on the movable platform 7 via bearings. A first motor 12 is fixed on the movable platform 7, and the first motor 12 directly drives the drive shaft to rotate. A first gear 13 and a synchronous pulley 14 are fixed on both the drive shaft and the driven shaft 11. A closed-loop synchronous belt 15 is wound around the synchronous pulley 14 on the drive shaft and the driven shaft 11 to achieve synchronous rotation of the drive shaft and the driven shaft 11 at the same speed. Two lamp holders 10 are each fixed with a rack 16 at the end of the mounting plate 17 away from the condenser cover 18. The two racks 16 precisely mesh with the first gears 13 on the drive shaft and the driven shaft 11, respectively. When the first motor 12 starts, the drive shaft drives the driven shaft 11 to rotate via the synchronous belt 15, causing the two first gears 13 to rotate. The two first gears 13 then drive the two racks 16 to move, thereby driving the two lamp holders 10 to move in the through slot 9, achieving axial movement of the lamp body 8.

[0037] Two opposing annular plates 19 are fixed inside the mounting cavity 4. Limiting rings 20 are fixed to the opposing sidewalls of both annular plates 19, and the bracket 2 passes through the inside of the limiting rings 20. A limiting conical surface is formed on the inner edge of the limiting rings 20. There are two annular frames 5, which are fixedly connected to the lamp holder 6 via multiple connecting rods 21, forming an integrated rotating structure. Positioning conical surfaces with angles matching the limiting conical surfaces are formed on the opposite end faces of the two annular frames 5. The two limiting conical surfaces abut against the two positioning conical surfaces, thus limiting the position of the annular frames 5. Multiple rollers are evenly arranged between the positioning and limiting conical surfaces, and the rollers roll in contact between the conical surfaces to achieve low-friction rotation. A second motor 22 is fixedly mounted on one of the annular plates 19. Continuous toothed patterns 23 are formed on the outer circumference of the annular frame 5 near the second motor 22. A second gear 24 that precisely meshes with the toothed patterns 23 is connected to the output shaft of the second motor 22. When the second motor 22 starts, it drives the ring frame 5 to rotate through the meshing of the second gear 24 and the tooth pattern 23, so that the lamp body 8 can rotate 360 ​​degrees around the bracket 2.

[0038] Through the above configuration, the focusing cover 18 significantly improves the utilization rate and uniformity of infrared energy, enhancing the treatment depth and effect; the first motor 12 directly drives a rack 16 to move through the first gear 13 of the drive shaft, while the synchronous belt 15 drives the driven shaft 11 to rotate synchronously, causing the other rack 16 to move synchronously. The two lamp holders 10 and the lamp body 8 can perform opposite axial displacements, thereby achieving precise adjustment of the axial position of the two lamp bodies 8 and changing the infrared irradiation range; the combination of the annular plate 19, the limiting ring 20, the positioning cone surface and the roller forms a high-precision, low-friction rotation support system, making the axial positioning of the annular frame 5 reliable, the operation smooth and the noise low when it rotates; the second motor 22 drives the annular frame 5 to achieve controllable continuous or intermittent rotation through the meshing of the toothed teeth 23 and the second gear 24, which allows the user to set the rotation speed and angle range according to the treatment needs, achieving precise 360-degree circumferential irradiation.

[0039] Example 3 Based on Embodiment 1 and Embodiment 2, this embodiment further optimizes the heat dissipation system of the lamp head, the auxiliary support and massage function of the bracket 2, and the external fixing connection method of the lamp head.

[0040] like Figures 1 to 3As shown, a cooling fan 25 is fixedly installed at one end of the lamp holder 6, with the blades of the cooling fan 25 facing inwards from the lamp holder 6. This fan is used for active air cooling of the lamp holder 6, adjustment mechanism, lamp body 8, and related motors. Multiple corresponding vents 26 are provided at both ends of the outer shell 1, arranged in a ring. When the cooling fan 25 rotates with the lamp holder 6, a vent 26 position is always aligned with the air inlet and outlet of the cooling fan 25. After the cooling fan 25 is activated, it drives external cold air into the outer shell 1 through one vent 26, providing forced convection cooling to the internal heat-generating components. The hot air, having absorbed heat, is then discharged through the other vent 26, forming a complete air circulation cooling path. Simultaneously, multiple axially extending heat dissipation fins 27 are uniformly fixed on the circumferential outer wall of the outer shell 1. This significantly increases the surface area of ​​the outer shell 1, achieving efficient passive heat dissipation and ensuring that the overall temperature of the lamp head remains within a safe and suitable range during long-term continuous operation, preventing high temperatures from adversely affecting the lifespan of the lamp body 8 and the therapeutic effect.

[0041] Since the first motor 12, the second motor 22, the third motor 30, the lamp body 8, and the cooling fan 25 all require power in this design, and these components need to rotate 360 ​​degrees around the bracket 2, a wiring ring 34 is fixed on one of the ring frames 5. The wiring ring 34 is provided with conductive rings corresponding to each electrical component, and the housing 1 is provided with brushes corresponding to the conductive rings. The specific electrical connection structure can be implemented by those skilled in the art using conventional technical means, and will not be described in detail in this embodiment.

[0042] Multiple parallel rollers 29 are rotatably mounted on the lower part of the bracket 2, and the rollers 29 are mounted on the lower side of the bracket 2 via bearings. A light-transmitting gap is left between adjacent rollers 29, and the surface of the rollers 29 is decorated with regularly distributed massage textures (such as raised stripes or ripples). The free rotation of the rollers 29 significantly reduces resistance when the limb moves on the bracket 2, allowing the user to move the limb back and forth autonomously during treatment. The light-transmitting gap ensures that infrared rays can continuously irradiate the limb surface through the gap, while the massage textures provide a gentle massage stimulation to the skin when the limb moves relative to the rollers 29, promoting local blood circulation and metabolism. Both the bracket 2 and the rollers 29 are covered with heat-resistant silicone. Silicone has poor thermal conductivity and does not easily transfer heat, preventing burns to the user.

[0043] A connecting arm 28 is hinged to the outer casing 1 via a hinge shaft. The other end of the connecting arm 28 is connected to an external bracket, allowing the lamp head to be flexibly fixed on the external bracket. The overall position of the lamp head can be flexibly adjusted by adjusting the hinge angle. A damping pad or bolt can be fitted onto the hinge shaft to facilitate fixing the hinge angle.

[0044] Through the above configuration, the cooling fan 25, combined with the vent 26, forms a highly efficient forced convection airflow channel, quickly removing the heat generated during the operation of the lamp body 8, motor, and adjustment mechanism. The heat dissipation fins 27 further enhance the passive heat dissipation capacity, ensuring the temperature stability and safety of the lamp head during long-term operation. The roller 29 reduces the resistance to limb movement, making it easier for users to adjust their posture or perform slight movements during treatment. The massage texture combined with limb movement provides additional auxiliary massage effects, enhancing the overall efficacy of infrared therapy. The hinged design of the connecting arm 28 gives the lamp head good flexibility and ease of installation, enabling adaptive installation at multiple angles and positions to meet the diverse needs of clinical and home use.

[0045] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
