Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a near-infrared physiotherapy device. Background Art

[0002] Near-infrared physiotherapy devices mainly utilize the thermal effect of infrared light. By emitting near-infrared light of a specific wavelength, the near-infrared physiotherapy device can penetrate the skin and directly cause thermal effects on muscles, subcutaneous tissues, etc., accelerating the removal of waste and transporting nutrients, strengthening the metabolism of local tissue cells, reducing pain, increasing muscle relaxation, and producing a massage effect. Existing near-infrared physiotherapy devices generally use a water filter and a filter to filter the light emitted by the light source. The light passes through the water filter and the filter in sequence. When the near-infrared physiotherapy device works for a long time, the liquid in the water filter will expand due to the increase in temperature, resulting in a large pressure inside the water filter and causing the liquid to easily leak; in addition, when the liquid in the water filter absorbs too much heat, due to the increase in liquid expansion pressure, an explosion may occur, which will pose a relatively large safety hazard to users.

Detailed implementation mode

[0019] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation mode of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0020] In the description of the present utility model, it should be understood that the present utility model uses the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] As Figures 1-4 , a near-infrared physiotherapy device according to a preferred embodiment of the present utility model includes an outer shell 1, a reflecting cup 2, a light source 3, a water filtering component 4, a filter sheet 5, and an optical film 6. The reflecting cup 2 is installed inside the outer shell 1. The front end of the reflecting cup 2 is the light outlet. The light source 3 is installed inside the reflecting cup 2. The water filtering component 4 is arranged on the front side of the reflecting cup 2. The filter sheet 5 is arranged on the front side of the water filtering component 4. The optical film 6 is arranged at the rear end of the water filtering component 4 and corresponds to the position of the light outlet of the reflecting cup 2. The optical film 6 can reflect light with a wavelength greater than the set wavelength and can allow light with a wavelength less than or equal to the set wavelength to pass through. It should be noted that this type of optical film 6 is a prior art. For example, a resin lens with an anti-infrared effect disclosed in a Chinese patent (application number: CN201010193580.2) is provided with an optical thin film layer that has a high reflection effect on near-infrared light and an anti-reflection effect on visible light. This optical thin film layer is composed of an alternating stack of a low refractive index material film layer and another high refractive index material film layer.

[0022] The working principle of this embodiment is as follows: The light emitted by the light source 3 is reflected by the reflector 2 and basically irradiates to the optical film 6. The optical film 6 can reflect the light with a wavelength greater than the set wavelength back into the reflector 2, and the remaining light (not greater than the set wavelength of the optical film 6) will pass through the optical film 6, pass through the water filtering component 4 and the filter 5 in sequence, and finally be emitted. The water filtering component 4 and the filter 5 filter the light respectively, so that the emitted light is near-infrared light with the required wavelength; the optical film 6 can reflect the light with a wavelength greater than the set wavelength. On the one hand, it can achieve the filtering effect and help reduce the temperature of the water filtering component 4 (the heat of the light transmitted to the water filtering component 4 is reduced); on the other hand, a part of the light reflected by the optical film 6 is reflected back into the reflector 2, which can increase the temperature at the light source 3, thus helping to increase the emissivity of the infrared radiation of the light source 3 and reduce the energy consumption of the light source 3, and the remaining light reflected by the optical film 6 is reflected inside the housing 1, which helps to dissipate heat.

[0023] Exemplarily, the water filtering component 4 includes a first mounting ring 41, a first glass sheet 43, a second mounting ring 42 and a second glass sheet 44. The first mounting ring 41 and the second mounting ring 42 are coaxially arranged and fit together. The first glass sheet 43 is fittingly mounted in the inner hole of the first mounting ring 41, and the second glass sheet 44 is fittingly mounted in the inner hole of the second mounting ring 42. A cavity 45 is provided between the first glass sheet 43 and the second glass sheet 44, and the cavity 45 is filled with a liquid (generally water). In this embodiment, the first mounting ring 41 is located at the rear side of the second mounting ring 42, the position of the first glass sheet 43 corresponds to the position of the reflector 2, the optical film 6 is covered on the rear end of the first glass sheet 43, and the filter 5 is mounted on the rear side of the second mounting ring 42 and corresponds to the position of the second glass sheet 44. The light passing through the optical film 6 passes through the first glass sheet 43, the cavity 45 and the second glass sheet 44 in sequence. The liquid in the cavity 45 plays a role in filtering and absorbing heat of the light. Generally, the materials of the first mounting ring 41 and the second mounting ring 42 are metals, which helps to dissipate heat.

[0024] Exemplarily, an expansion cavity 46 communicating with the cavity 45 is provided between the first mounting ring 41 and the second mounting ring 42. The expansion cavity 46 is annular. As Figure 4 shown, the setting of the expansion cavity 46 plays a role in decompression and heat dissipation.

[0025] Exemplarily, a sealing ring 461 is provided between the first mounting ring 41 and the second mounting ring 42. The position of the sealing ring 461 corresponds to the position of the expansion cavity 46 to ensure the sealing of the expansion cavity 46 and prevent the liquid from leaking.

[0026] Exemplarily, a plurality of heat dissipation fins 47 are respectively arranged at intervals on the outer peripheries of the first mounting ring 41 and the second mounting ring 42, which helps to improve the heat dissipation efficiency of the first mounting ring 41 and the second mounting ring 42.

[0027] Exemplarily, a connecting cover 12 is installed inside the housing 1, the reflecting cup 2 is arranged inside the connecting cover 12, and the reflecting cup 2 is connected to the connecting cover 12 through a connecting member for the installation and fixation of the reflecting cup 2. There is a spacing between the outer side of the connecting cover 12 and the inner side of the housing 1, which can play a certain heat insulation effect (the connecting cover 12 can be made of heat-insulating material) to prevent the temperature of the side part of the housing 1 from being too high.

[0028] Exemplarily, a fixing seat 11 is provided on the side part of the housing 1, and the fixing seat 11 is provided with a telescopic rod 13 that can be telescopically adjusted. The telescopic rod 13 is arranged along the axial direction of the housing 1, and the setting of the telescopic rod 13 helps to determine the safe distance between the device and the irradiated object.

[0029] Exemplarily, the device further includes a bracket 14. The bracket 14 is U-shaped, and both sides of the bracket 14 are rotatably connected to the side part of the housing 1, which helps to place the housing 1 and adjust the irradiation angle of the device.

[0030] Exemplarily, a heat dissipation hole 15 is provided at the rear end of the housing 1, and a heat dissipation fan 16 corresponding to the position of the heat dissipation hole 15 is installed inside the housing 1, which helps to dissipate the heat inside the housing 1.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
