Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a multi-band portable laser therapy device. Background Technology

[0002] Multi-band portable laser therapy equipment is a type of medical device manufactured based on laser technology. Medical laser therapy devices use lasers of different wavelengths and powers to irradiate the treatment area, achieving the therapeutic purpose by stimulating and regulating the biological responses of human cells. With the continuous development of laser technology, the application of laser therapy devices in the medical field is becoming more and more widespread.

[0003] Currently, laser therapy devices consist of a main unit and a laser probe. The laser probe is connected to the main unit via an optical cable. The main unit includes a power supply circuit, a control circuit, and a laser generation circuit. The power supply module performs power conversion to provide power to the therapy device. The laser generation circuit provides the laser required by the therapy device. The control circuit can adjust the laser irradiation wavelength and power to switch between different treatment modes to meet the needs of different groups of people.

[0004] In related technologies, laser therapy devices generate a large amount of heat during use, requiring excellent heat dissipation. Therefore, laser therapy devices typically have multiple heat sinks, usually made of copper or aluminum. In addition, a cooling fan is also required inside the device. However, the position of the cooling fan is usually fixed, which means that the airflow can only be directed to a fixed location. This results in airflow not being able to circulate in some areas of the device in a timely manner, leading to low overall heat dissipation efficiency and an inability to achieve rapid heat dissipation, thus affecting its usability. Utility Model Content

[0005] To address the problem that the fixed position of the fan in current laser therapy devices results in a fixed airflow path, which cannot fully and quickly drive the airflow inside the device, leading to low heat dissipation efficiency, this application provides a multi-band portable laser therapy device.

[0006] The multi-band portable laser therapy device provided in this application adopts the following technical solution:

[0007] A multi-band portable laser therapy device, comprising:

[0008] The laser therapy device body has a heat dissipation base at its bottom, an installation cavity inside the heat dissipation base, and heat dissipation holes through the bottom of the heat dissipation base.

[0009] A heat dissipation mechanism is used to drive the rapid airflow inside the laser therapy device body. The heat dissipation mechanism is set in the mounting cavity of the heat dissipation base. The heat dissipation mechanism includes a fixed cylinder, a linkage cylinder, a support plate and a fan. The fixed cylinder is fixed at the bottom center of the mounting cavity of the heat dissipation base. The linkage cylinder is slidably engaged inside the fixed cylinder. The support plate is fixed at one end of the linkage cylinder and the fan is fixed on the support plate.

[0010] A transmission mechanism is used to drive the linkage cylinder to slide inside the fixed cylinder, and the transmission mechanism is located at the bottom of the fixed cylinder.

[0011] By adopting the above technical solution, the fan drives the airflow inside the heat dissipation base, thereby achieving the heat dissipation effect on the laser therapy device. At the same time, the transmission mechanism drives the linkage cylinder to slide inside the fixed cylinder. As the linkage cylinder slides, it can deflect, which in turn causes the fan angle to deflect. This allows the fan to quickly and comprehensively drive the airflow inside the heat dissipation base, avoiding the situation where the fan angle is fixed, which would prevent the airflow from flowing quickly. This method is simple, efficient, and practical.

[0012] Optionally, the heat dissipation mechanism further includes a transmission rod, a contact rod, and a driven rod. The transmission rod is rotatably connected to the bottom of the fixed cylinder, with part of the transmission rod located inside the fixed cylinder and part located outside the fixed cylinder. A C-shaped seat is fixed to one end of the transmission rod located inside the fixed cylinder. Two contact rods are fixed at the edge of the C-shaped seat and are symmetrically arranged. The driven rod is connected to the linkage cylinder and is slidably engaged between two adjacent contact rods.

[0013] By adopting the above technical solution, the transmission rod drives the abutment rod to rotate, and then the abutment rod limits the driven rod, so that the driven rod can drive the linkage cylinder to slide inside the fixed cylinder.

[0014] Optionally, the heat dissipation mechanism further includes a limiting groove, a limiting plate, and a support plate. The limiting groove is disposed through the side wall of the fixed cylinder. The support plate is fixed on the outer wall of the fixed cylinder and spans the limiting groove. The limiting plate is fixed at the bottom of the support plate and located inside the limiting groove. One end of the driven rod is slidably engaged in the gap between the limiting groove and the limiting plate.

[0015] By adopting the above technical solution, the driven rod is limited by the limiting groove and the limiting plate, and the driven rod causes the linkage cylinder to deflect to a certain extent when it slides in the fixed cylinder.

[0016] Optionally, rollers are rotatably sleeved at both the upper and lower ends of the driven rod, and the two rollers are respectively located between two adjacent abutment rods and in the gap between the limiting groove and the limiting plate.

[0017] By adopting the above technical solution, the frictional resistance of the driven rod during linkage is reduced by utilizing the rolling of the roller.

[0018] Optionally, the transmission mechanism includes a driven incomplete gear, a driving incomplete gear, and a micro servo motor. The driven incomplete gear is coaxially fixed to one end of the transmission rod located outside the fixed cylinder. The micro servo motor is fixed to the bottom of the fixed cylinder. The driving incomplete gear is coaxially fixed to the output shaft of the micro servo motor, and the driven incomplete gear and the driving incomplete gear mesh with each other.

[0019] By adopting the above technical solution, a micro servo motor is used to drive the active incomplete gear to rotate, which in turn drives the driven incomplete gear to mesh and link together, and the driven incomplete gear drives the transmission rod to rotate.

[0020] Optionally, an arc-shaped groove is provided at the edge of the driven incomplete gear, and an arc-shaped protrusion is provided at the edge of the driving incomplete gear, with the arc-shaped protrusion slidingly abutting against the arc-shaped groove.

[0021] By adopting the above technical solution, the driven incomplete gear is limited by the arc-shaped convex plate and arc-shaped groove.

[0022] Optionally, a lever is fixed to the bottom of the driven incomplete gear, and a stop bar is fixed to the bottom edge of the driving incomplete gear, with one end of the lever slidingly abutting against the stop bar.

[0023] By adopting the above technical solution, the lever is used to move the lever, which in turn drives the driven incomplete gear to rotate, so that the driven incomplete gear can quickly mesh and engage with the driving incomplete gear.

[0024] Optionally, two support plates are provided, which are respectively located at both ends of the linkage cylinder, and the two support plates have different inclination angles.

[0025] By adopting the above technical solution, the fan is supported by support plates with different tilt angles, thereby enabling the airflow inside the heat sink base to circulate more quickly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] This invention utilizes a fan to drive airflow within the heat dissipation base, thereby achieving heat dissipation for the laser therapy device. Simultaneously, a transmission mechanism drives a linkage cylinder to slide within a fixed cylinder. As the linkage cylinder slides, it deflects, which in turn deflects the fan's angle. This allows the fan to quickly and comprehensively circulate airflow within the heat dissipation base, avoiding the situation where a fixed fan angle prevents airflow from being efficient. This invention is simple, efficient, and practical. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a multi-band portable laser therapy device.

[0039] Reference Figure 1 and Figure 2 A multi-band portable laser therapy device includes a laser therapy instrument body 1, a heat dissipation base 2, heat dissipation holes 3, a heat dissipation mechanism 4, and a transmission mechanism 5. The heat dissipation base 2 is located at the bottom of the laser therapy instrument body 1. The heat dissipation base 2 has an internal mounting cavity and a heat dissipation hole 3 is provided through the bottom of the heat dissipation base 2. The heat dissipation mechanism 4 is located in the mounting cavity of the heat dissipation base 2. The transmission mechanism 5 is located at the bottom of the fixed cylinder 41. A fan 44 drives the airflow inside the heat dissipation base 2, thereby achieving the heat dissipation effect on the laser therapy instrument body 1. At the same time as heat dissipation, the transmission mechanism 5 drives the linkage cylinder 42 to slide inside the fixed cylinder 41. As the linkage cylinder 42 slides, it can deflect, thereby causing the fan 44 to deflect at an angle. This allows the fan 44 to quickly and comprehensively drive the airflow inside the heat dissipation base 2, avoiding the situation where the fan 44 is fixed at an angle, which would prevent the airflow from flowing quickly. It is simple, efficient, and practical.

[0040] Reference Figure 3 and Figure 4 Specifically, the heat dissipation mechanism 4 includes a fixed cylinder 41, a linkage cylinder 42, a support plate 43, a fan 44, a transmission rod 45, a contact rod 46, and a driven rod 47. The fixed cylinder 41 is fixed at the center of the bottom of the mounting cavity of the heat dissipation base 2. The linkage cylinder 42 is slidably engaged inside the fixed cylinder 41. The support plate 43 is fixed at one end of the linkage cylinder 42. The fan 44 is fixed on the support plate 43. The transmission rod 45 is rotatably connected to the bottom of the fixed cylinder 41, and part of the transmission rod 45 is located inside the fixed cylinder 41. Part of it is located outside the fixed cylinder 41, and a C-shaped seat is fixed at one end of the transmission rod 45 inside the fixed cylinder 41. The abutment rod 46 is fixed at the edge of the C-shaped seat, and two rods are symmetrically arranged. The driven rod 47 is connected to the linkage cylinder 42 and is slidably engaged between two adjacent abutment rods 46. The transmission rod 45 drives the abutment rod 46 to rotate, and then the abutment rod 46 limits the driven rod 47, so that the driven rod 47 can drive the linkage cylinder 42 to slide inside the fixed cylinder 41.

[0041] In this embodiment of the application, the heat dissipation mechanism 4 further includes a limiting groove 48, a limiting plate 49, and a support plate 410. The limiting groove 48 and the limiting plate 49 limit the driven rod 47, and the driven rod 47 causes the linkage cylinder 42 to slide within the fixed cylinder 41, resulting in a certain degree of deflection.

[0042] Specifically, the limiting groove 48 is provided through the side wall of the fixed cylinder 41, the support plate 410 is fixed on the outer wall of the fixed cylinder 41 and spans the limiting groove 48, the limiting plate 49 is fixed at the bottom of the support plate 410 and located in the limiting groove 48, and one end of the driven rod 47 is slidably engaged in the gap between the limiting groove 48 and the limiting plate 49.

[0043] In this embodiment, rollers are rotatably sleeved at both the upper and lower ends of the driven rod 47, and the two rollers are respectively located between two adjacent abutment rods 46 and in the gap between the limiting groove 48 and the limiting plate 49. The rolling of the rollers reduces the frictional resistance of the driven rod 47 during linkage.

[0044] Reference Figure 5 and Figure 6 Specifically, in this embodiment of the application, the transmission mechanism 5 includes a driven incomplete gear 51, a driving incomplete gear 52, a micro servo motor 53, a lever 54, and a stop lever 55. The micro servo motor 53 drives the driving incomplete gear 52 to rotate, which in turn drives the driven incomplete gear 51 to mesh and link. The driven incomplete gear 51 drives the transmission rod 45 to rotate, and at the same time, the stop lever 55 moves the lever 54, which in turn drives the driven incomplete gear 51 to rotate, so that the driven incomplete gear 51 can quickly mesh and link with the driving incomplete gear 52.

[0045] In this embodiment, the driven incomplete gear 51 is coaxially fixed to one end of the transmission rod 45 located outside the fixed cylinder 41, the micro servo motor 53 is fixed to the bottom of the fixed cylinder 41, and the driving incomplete gear 52 is coaxially fixed to the output shaft of the micro servo motor 53. The driven incomplete gear 51 and the driving incomplete gear 52 mesh with each other. A lever 54 is fixed to the bottom of the driven incomplete gear 51, and a stop bar 55 is fixed to the bottom edge of the driving incomplete gear 52. One end of the lever 54 slides against the stop bar 55.

[0046] Specifically, in this embodiment of the application, regarding the driven incomplete gear 51, an arc-shaped groove is provided at the edge of the driven incomplete gear 51, and an arc-shaped protrusion is provided at the edge of the driving incomplete gear 52. The arc-shaped protrusion slides against the arc-shaped groove, and the arc-shaped protrusion and the arc-shaped groove are used to limit the driven incomplete gear 51.

[0047] There are two support plates 43, which are respectively located at both ends of the linkage cylinder 42. The two support plates 43 have different inclination angles. The fan 44 is supported by the support plates 43 with different inclination angles, so that the airflow inside the heat sink 2 can circulate more quickly.

[0048] The implementation principle of a multi-band portable laser therapy device according to an embodiment of this application is as follows: First, laser therapy is performed on the patient through the laser therapy instrument body 1. At the same time, the laser therapy instrument body 1 is cooled by the fan 44. Simultaneously, the micro servo motor 53 drives the active incomplete gear 52 to rotate, which in turn drives the driven incomplete gear 51 to mesh and link. The driven incomplete gear 51 drives the transmission rod 45 to rotate, which links the abutment rod 46. The abutment rod 46 drives the driven rod 47 to slide in the gap between the limiting groove 48 and the limiting plate 49. Thus, the linkage cylinder 42 can slide back and forth in the fixed cylinder 41 under the limiting action of the driven rod 47, and can also deflect to a certain extent.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
