Description

Technical Field

[0001] This invention relates to the field of spectral therapy technology, and in particular to a miniaturized high-power near-infrared spectral therapy device. Background Technology

[0002] A spectral therapy device is a medical device that uses light of different wavelengths to perform spectral radiation therapy on the human body. It is used for tissue damage, inflammation and pain relief, and to promote local blood circulation. The working principle of existing spectral therapy devices is relatively simple; they mainly use a light source and filters to output light energy of specific wavelengths to irradiate the desired areas of the body for spectral radiation therapy.

[0003] Currently, existing high-power spectral therapy equipment is not only large in size but also expensive, which undoubtedly limits its widespread application. Existing spectral therapy equipment is mainly used in hospitals and physiotherapy centers. To accelerate the promotion of spectral therapy technology and broaden its application scope, miniaturizing spectral therapy equipment is a trend. This not only significantly reduces the footprint but also lowers costs. While miniaturizing individual components is relatively easy, it also introduces the problem of liquid temperature rise and expansion within the filter. If the liquid temperature rise is not effectively controlled, it can lead to leakage or even explosion.

[0004] In the past, the filters in spectral therapy devices were large, resulting in a large contact area between the liquid and the filter housing. With existing heat dissipation measures, the heat dissipation requirements were generally met, and the liquid temperature rise could be effectively controlled. However, with miniaturization, the filter size has been reduced, and in order to maintain the high-power design to ensure the spectral radiation therapy effect, the liquid temperature rises faster, and the heat is difficult to transfer in time. This can ultimately lead to uncontrolled liquid temperature rise, excessive liquid expansion, and technical problems such as sealing failure, leakage, or even explosion. Summary of the Invention

[0005] This invention provides a miniaturized high-power near-infrared spectroscopy therapy device, solving the problems existing in the prior art. By redesigning and optimizing the heat dissipation system of the spectral therapy device, heat dissipation efficiency is significantly improved, and the liquid temperature rise is effectively controlled, thereby meeting the heat dissipation requirements of high-power miniaturized design. By redesigning and optimizing the filter structure, the contact area between the liquid and the filter housing is increased while meeting the structural strength design requirements. At the same time, explosion-proof measures are added, making the spectral therapy device safer and more reliable to use.

[0006] One of the technical solutions adopted in this invention is: A miniaturized high-power near-infrared spectroscopy therapy device includes a base with a head unit. The head unit includes a housing. Inside the housing, from back to front, are arranged a light source, a reflector, and a filter. The outer wall of the filter has heat dissipation fins. The lower side wall of the housing has several heat dissipation holes. An air guide shroud is located inside the housing. An air guide plate is located at the front end of the air guide shroud. The reflector is located inside the air guide shroud and its front end is spaced apart from the air guide plate. The air guide plate is spaced apart from the filter. A ventilation hole is located in the center of the air guide plate. An air inlet is located at the front end of the air guide shroud, and an air outlet is vertically located at the rear end. A cooling fan is located below the air outlet and is located inside the housing. Under the action of the cooling fan, air flows from the airflow channel between two adjacent heat dissipation fins to the air guide plate. Under the action of the air guide plate, the air flows to the ventilation hole and enters the air guide shroud through the air inlet. The air flows vertically downward through the air outlet on the air guide shroud and is discharged from the heat dissipation hole by the cooling fan for heat dissipation.

[0007] The filter includes a lens housing with heat dissipation fins on its outer wall and a through hole in the center. A liquid storage chamber A is located inside the lens housing, and a filtering mechanism is sealed within the liquid storage chamber A corresponding to the through hole. A liquid storage chamber B is located within the filtering mechanism. Liquid storage chamber A and liquid storage chamber B are connected. An injection port communicating with liquid storage chamber A is located on one side of the lens housing. A pressure switch is connected to the injection port, and the pressure switch is connected to a discharge container.

[0008] The outer surface of the mirror housing is coated with graphene.

[0009] The mirror housing is designed as a split unit consisting of a left mirror housing and a right mirror housing. The left mirror housing has multiple filter threaded holes spaced apart along the circumference, and the corresponding right mirror housing has multiple filter mounting holes spaced apart along the circumference. Filter screws are provided on the filter mounting holes and filter threaded holes to connect the left and right mirror housings together. A sealing groove and a sealing ring are provided between the left and right mirror housings. Two ear plates are symmetrically provided on the side wall of the left mirror housing. The ear plates are respectively provided with mounting holes A and B. A probe is provided on mounting hole B.

[0010] The left mirror housing is provided with a light-concentrating protective cover, which is installed on the filter thread hole by an external screw. The light-concentrating protective cover is designed in a trumpet shape.

[0011] The mirror housing has a mounting groove A corresponding to the through hole, and the mounting groove A has a sealing groove A and a sealing ring A. The filtering mechanism includes a support ring, and mounting grooves B are respectively provided on both sides of the support ring. The mounting grooves B have a sealing groove B and a sealing ring B. A filter is provided on the mounting grooves B, with a portion of the filter disposed in the mounting grooves B and the remaining portion installed in the mounting grooves A. The two filters and the support ring cooperate to form a liquid storage cavity B. The support ring has a plurality of connecting holes spaced along the circumferential direction to connect the liquid storage cavity A and the liquid storage cavity B.

[0012] The housing comprises an upper housing and a lower housing with a split design. The upper housing has multiple upper columns spaced apart, each with threaded holes. Correspondingly, the lower housing has multiple lower columns spaced apart, each with mounting holes. Screws are installed in the mounting holes and threaded holes to connect the upper and lower housings. The upper housing also has multiple columns spaced apart, each with threaded holes. A fan guide has multiple mounting holes spaced apart, with screws installed in these holes to mount the fan guide onto the upper housing. The lower housing has mounting seats on both sides of its front end, each with a threaded hole A. Screws A are installed in the mounting holes A and threaded holes A to mount a filter onto the lower housing. The lower end of the lower housing has four fan columns spaced apart, each with threaded holes. Cooling fans are secured to the fan columns with fan screws.

[0013] The air guide cover includes an upper air guide cover and a lower air guide cover with a split design. The lower air guide cover has a vertical air outlet at its rear end. The upper and lower air guide covers have wing plates on their side plates. The wing plates have multiple mounting holes. The rear ends of the air guide plates have mounting plates on their side plates. The mounting plates have waist-shaped holes that are aligned with the mounting holes located at the front end of the wing plates.

[0014] The front end of the reflector is mounted on the air guide plate via multiple hexagonal isolation posts, fastening nuts, and fastening screws.

[0015] The heat dissipation fins are inclined inward on both sides.

[0016] The lower housing has a support column at its lower center. Multiple stiffeners are spaced apart between the support column and the lower housing along the circumferential direction. A flow guide is provided on the support column. The flow guide is designed in the shape of a frustum. An avoidance opening is provided on the flow guide at the position corresponding to the stiffener. The flow guide directs air to the heat dissipation holes.

[0017] The machine head is mounted on the machine base.

[0018] The beneficial effects of this invention are: (1) By designing structures such as heat dissipation fins, air guide plates, air guide covers, heat dissipation fans and flow guide covers, the airflow direction is redesigned. This not only allows the airflow to carry away heat through the airflow channel between two adjacent heat dissipation fins, but also allows the airflow to flow radially from the outside to the inside to dissipate heat to the right mirror shell located on the inside. Then, when passing through the air guide cover, it can dissipate heat to the inside and outside of the reflector cup. The airflow is allowed to flow vertically downward through the air outlet, and then directly out of the heat dissipation hole through the flow guide cover. By changing the airflow direction, more comprehensive and efficient heat dissipation of the filter is achieved, significantly improving the convective heat transfer effect. (2) By designing two liquid storage chambers, A and B, inside the filter, not only are the light filtering requirements met, but the contact area between the liquid and the mirror shell is also increased, thereby improving the heat transfer rate. The combination of the two can significantly improve the heat dissipation efficiency, so that the liquid temperature rise can be effectively controlled. (3) By designing a pressure switch and a discharge container at the injection port, it can play the role of early warning and explosion prevention, making it safer. Attached Figure Description

Detailed Implementation

[0020] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0022] like Figure 1-17As shown, a miniaturized high-power near-infrared spectroscopy therapy device includes a head unit 1, which is mounted on a base 74. The base 74 can be adaptively designed according to the size of the head unit 1 and the specific application scenario. For example, the head unit 1 can be miniaturized by adopting the above-described technical solution of this application, and the corresponding base 74 can also be miniaturized. For example, as shown... Figure 17 As shown, the head unit 1 and base 74 can be designed as a structure similar to a desk lamp, thereby reducing the footprint and facilitating widespread application. The head unit 1 includes a housing 2, inside which, from back to front, are arranged a light source 3, a reflector 4, and a filter 5. The filter 5 has heat dissipation fins 6 on its outer wall. The lower side wall of the housing 2 has several heat dissipation holes 7. In practical applications, the lower end of the housing 2 usually needs to be connected to the base 74, so the heat dissipation holes 7 can only be set on the side wall of the housing 2. Considering the structural strength required for the housing 2, the heat dissipation holes 7 are usually arranged in a row at intervals. The housing 2 has an air guide shroud 8, and the front end of the air guide shroud 8 has an air guide plate 9. The reflector 4 is set inside the air guide shroud 8 and its front end is spaced apart on the air guide plate 9. As is well known, the reflector cup 4 has a large opening at the front end and a smaller opening at the rear end on the air guide plate 9. This makes it difficult to meet the airflow exhaust requirements by relying solely on the reflector cup 4, thus limiting the heat dissipation efficiency. This application forms an airflow channel by spaced-apart the reflector cup 4 and the air guide plate 9. In this way, the airflow can not only be guided through the reflector cup 4, but also enter the channel between the air guide cover 8 and the reflector cup 4 through the airflow channel. The two finally converge and are discharged from the air outlet 12, significantly improving the heat dissipation efficiency. The air guide plate 9 is spaced apart from the filter 5. The air guide plate 9 has a ventilation hole 10 in the center. The air guide cover 8 has an air inlet 11 at the front end and an air outlet 12 vertically at the rear end. Here, the size of the air outlet 12 is designed to be as large as possible. Figure 6As shown, it meets the ventilation requirements; a cooling fan 13 is provided at the lower end of the air outlet 12, and the cooling fan 13 is installed inside the casing 2; under the action of the cooling fan 13, air flows from the airflow channel 14 between two adjacent heat dissipation fins 6 to the air guide plate 9, and under the action of the air guide plate 9, the air flows to the ventilation hole 10 and enters the air guide shroud 8 through the air inlet 11. The air flows vertically downward through the air outlet 12 on the air guide shroud 8 and is discharged from the heat dissipation hole 7 by the cooling fan 13 for heat dissipation. Compared with existing technologies, this application redesigns the airflow direction by designing structures such as heat dissipation fins 6, air guide plates 9, air guide covers 8, and cooling fans 13. This not only allows airflow to carry away a large amount of heat through the airflow channel 14 between two adjacent heat dissipation fins 6, but also allows the airflow to flow radially from the outside to the inside to dissipate heat from the right mirror shell 24 located on the inner side, thanks to the action of the air guide plate 9. Then, when passing through the air guide cover 8, it can dissipate heat from both the inside and outside of the reflector cup 4. Finally, the airflow flows vertically downward through the air outlet 12 and is discharged from the heat dissipation hole 7. This technical solution significantly improves the convective heat transfer effect, improves the heat dissipation efficiency of the filter 5, and effectively controls the temperature rise of the liquid inside the filter 5. It is especially suitable for miniaturized filters and miniaturized spectral therapy equipment.

[0023] The filter 5 includes a lens housing 15, with heat dissipation fins 6 on its outer wall. A through-hole 16 is located at the center of the lens housing 15. A liquid storage chamber A17 is located inside the lens housing 15. A filtering mechanism 18 is sealed within the liquid storage chamber A17 corresponding to the through-hole 16. A liquid storage chamber B19 is located within the filtering mechanism 18. The liquid storage chambers A17 and B19 are connected. An injection port 20, connected to the liquid storage chamber A17, is located on one side of the lens housing 15. A pressure switch 21 is connected to the injection port 20, and the pressure switch 21 is connected to a discharge container 22. By providing two liquid storage chambers, A17 and B19, within the filter 5, the contact area between the liquid and the lens housing 15 can be significantly increased, thereby improving the heat transfer rate. Combined with the aforementioned heat dissipation technology, this further enhances heat dissipation efficiency, allowing for better control of the liquid temperature rise. By designing the pressure switch 21 and the vent container 22, not only can explosion-proof warnings be provided, but the vent container 22 also provides explosion-proof protection, further improving the safety of the filter 5. In practical applications, the spectral therapy equipment is equipped with a control system (mainly for functions such as power on / off, time recording, temperature monitoring, and communication). The control motherboard 75 in the control system can be installed inside the upper housing 45 (specifically, as shown in the image). Figure 7 As shown, a pressure switch 21 is connected to the control system via a mounting column 76 on the upper housing 45 to monitor the pressure inside the filter 5 in real time and to trigger an alarm.

[0024] The outer surface of the mirror housing 15 is coated with graphene. The graphene coating, together with the heat dissipation fins 6 and the dual-cavity structure design, can further improve heat dissipation efficiency, thereby helping to reduce the liquid temperature.

[0025] The lens housing 15 adopts a split design, consisting of a left lens housing 23 and a right lens housing 24. The left lens housing 23 has multiple filter threaded holes 25 spaced along its circumference, and the corresponding right lens housing 24 has multiple filter mounting holes 26 spaced along its circumference. Filter screws 27 are provided on the filter mounting holes 26 and the filter threaded holes 25 to connect the left lens housing 23 and the right lens housing 24 together. A sealing groove 28 and a sealing ring 29 are provided between the left lens housing 23 and the right lens housing 24. The sealing ring 29 can be an O-ring or a T-ring. Two ear plates 30 are symmetrically provided on the side wall of the left lens housing 23. The ear plates 30 have mounting holes A31 and B32 respectively, and a probe 33 is provided on the mounting hole B32. The specific structure of the filter 5 is given. The split design of the lens housing 15 meets the requirements of the processing and assembly process, and the use of threaded connections and sealing measures meets the structural strength and sealing requirements.

[0026] A focusing protective cover 34 is provided on the outer side of the left mirror housing 23. The focusing protective cover 34 is installed on the filter thread hole 25 by an external screw 35. The focusing protective cover 34 is designed in a trumpet shape. The design of the focusing protective cover 34 not only helps to prevent burns and makes it safer to use, but also has a certain focusing effect, which helps to improve the effect of spectral therapy.

[0027] The mirror housing 15 has a mounting groove A36 corresponding to the through hole 16, and the mounting groove A36 has a sealing groove A37 and a sealing ring A38. The filtering mechanism 18 includes a support ring 39, and mounting grooves B40 are respectively provided on both sides of the support ring 39. The mounting groove B40 has a sealing groove B41 and a sealing ring B42. A filter 43 is provided on the mounting groove B40. A part of the filter 43 is disposed in the mounting groove B40, and the remaining part is installed in the mounting groove A36. The two filters 43 and the support ring 39 cooperate to form a liquid storage cavity B19. The support ring 39 has a plurality of connecting holes 44 spaced along the circumferential direction to connect the liquid storage cavity A17 and the liquid storage cavity B19. The specific structure of the filter mechanism 18 is given. Relying on the support ring 39, the filter 43 is sealed on both sides to form the liquid storage cavity B19 while being sealed in the mirror housing 15. The overall structure design is simple, easy to assemble, and has good sealing performance. Since the liquid storage cavity B19 and the liquid storage cavity A17 are connected, the liquid temperature rise and expansion mainly act on the mirror housing 15. Due to the higher structural strength of the mirror housing 15 and the use of sealing measures, the overall structure of the filter 5 meets the design requirements.

[0028] The housing 2 includes an upper housing 45 and a lower housing 46 with a split design. The upper housing 45 has multiple upper columns 47 spaced apart, each with a housing threaded hole 48. Correspondingly, the lower housing 46 has multiple lower columns 49 spaced apart, each with a housing mounting hole 50. Housing screws 51 connect the upper housing 45 and the lower housing 46 via the housing mounting holes 50 and the housing threaded holes 48. The upper housing 45 also has multiple columns 52 spaced apart, each with a threaded hole 53. The air guide shroud 8 is located on... Multiple mounting holes 54 are provided at intervals. Screws 55 are provided on the mounting holes 54 and threaded holes 53 to install the air guide cover 8 on the upper housing 45. Mounting seats 56 are provided on both sides of the front end of the lower housing 46. The mounting seats 56 are provided with threaded holes A57. Screws A58 are provided on the mounting holes A31 and threaded holes A57 to install the filter 5 on the lower housing 46. Four fan columns 59 are provided at intervals at the lower end of the lower housing 46. Fan threaded holes 60 are provided on the fan columns 59. The cooling fan 13 is fastened to the fan columns 59 by fan screws 61. By adopting a split design for the housing 2, the added air guide shroud 8 is fastened to the upper housing 45 by threaded connection. The reflector cup 4 is installed on the air guide plate 9, and the air guide plate 9 is installed on the air guide shroud 8. This not only achieves the installation of the three components, but also allows for precise determination of their relative positions. The filter 5 is installed at the front end of the lower housing 46, and the cooling fan 13 is installed at the lower end of the lower housing 46. The overall structural layout is more reasonable. During assembly, components can be installed on the upper housing 45 and the lower housing 46 respectively, which not only improves installation efficiency but also provides ample installation space. Finally, the upper housing 45 and the lower housing 46 are assembled together.

[0029] The air guide shroud 8 includes an upper air guide shroud 62 and a lower air guide shroud 63 with a split design. The lower air guide shroud 63 has a vertical air outlet 12 at its rear end. The upper air guide shroud 62 and the lower air guide shroud 63 each have a wing plate 64 on their side plates. The wing plate 64 has multiple mounting holes 54. The air guide plate 9 has mounting plates 65 on its rear side plates. The mounting plates 65 have waist-shaped holes 66, which are aligned with the mounting holes 54 located at the front end of the wing plate 64. By designing wing plates 64 on the air guide shroud 8, not only are the installation requirements of the air guide shroud 8 itself met, but the installation of the air guide plate 9 is also achieved, which has the advantages of convenient installation and high structural strength.

[0030] The front end of the reflector cup 4 is mounted on the air guide plate 9 via multiple hexagonal isolation posts 67, fastening nuts 68, and fastening screws 69. The specific structure of the reflector cup 4 and the air guide plate 9 being spaced apart is shown, which has the advantage of a robust and reliable installation structure.

[0031] The heat dissipation fins 6 are inclined inward on both sides, as can be seen in the following reference. Figure 12As shown. This design makes it easier for airflow to flow in the direction of the ventilation holes 10 of the guide vane 9.

[0032] A support column 70 is located at the center of the lower end of the lower housing 46. Multiple ribs 71 are spaced circumferentially between the support column 70 and the side wall of the lower housing 46. A guide shroud 72 is mounted on the support column 70. The guide shroud 72 is designed in a frustum shape, and clearance openings 73 are provided on the guide shroud 72 corresponding to the positions of the ribs 71. The guide shroud 72 guides air to the heat dissipation holes 7. In practical applications, considering the strength of the housing and the fact that the bottom of the housing 2 is usually used for mounting on the base 74, the heat dissipation holes 7 are typically located on the side wall of the lower end of the housing 2. This leaves space between the heat dissipation holes and the bottom of the housing, causing the vertically downward airflow to be unable to exit directly from the heat dissipation holes 7 immediately. Instead, it rushes towards the bottom of the housing 2, bounces off the bottom, returns, diffuses outwards, and finally exits from the heat dissipation holes 7. This undoubtedly affects the airflow efficiency. By designing the guide shroud 72, the airflow can be directly guided to the heat dissipation holes 7, thereby helping to improve heat dissipation efficiency.

[0033] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0034] Any aspects of this invention not described in detail are well-known to those skilled in the art.
