[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Please combine Figures 1-8 This embodiment proposes a 670nm red light health care device, characterized in that it includes an aluminum alloy shell 1, a magnet 6, a soft-pack lithium battery 7, a circuit board 8, a diffuse reflector 12, and a light-transmitting mask 11. The red light wavelength of the nursing device is 600-1000nm, and the aluminum alloy shell 1 is drum-shaped. The bottom surface inside the aluminum alloy shell 1 has a magnet fixing position 2, and the magnet 6 is assembled at the magnet fixing position 2. The aluminum alloy shell 1 also has a switch button position 3 and a Type-C port 4. One end of the circuit board 8 is fitted and connected to the Type-C port 4, and the other end is fitted and connected to the switch button position 3. A switch button 15 with hook teeth is inserted into the switch button position 3.
[0022] A soft-pack lithium battery 7 is stacked on top of a magnet 6. A circuit board 8 is stacked on top of the soft-pack lithium battery 7 and welded to it. A diffuse reflector 12 is stacked on top of the circuit board 8. A light-transmitting mask 11 is mounted on top of the diffuse reflector 12 and fits into the aluminum alloy shell 1.
[0023] The specific technical solution is that the core power supply of the device is a soft-pack lithium battery 7, which is welded to a circuit board 8 that integrates various electronic components to provide working power for the entire nursing device; the Type-C port 4 is embedded and connected to the circuit board 8, and external charging devices can replenish the power of the soft-pack lithium battery 7 through the Type-C port 4. During the charging process, the charging blue LED 10 on the circuit board 8 receives the electrical signal of the circuit board 8 and emits blue light to realize the visual prompt of the charging status.
[0024] Furthermore, the switch button 15 is equipped with a reset spring. One end of the reset spring abuts against the bottom of the inner cavity of the switch button 15, and the other end abuts against the inner wall of the switch button position 3 of the aluminum alloy shell 1, so as to realize the reset of the switch button 15 when pressed.
[0025] Power on / off control is achieved by the switch button 15 in conjunction with the self-locking switch on the circuit board 8. Pressing the switch button 15 with a reset spring triggers the self-locking switch on the circuit board 8, completing the switching of circuit on / off. After being pressed, the switch button 15 rebounds and resets through the built-in reset spring, ensuring the continuity of the pressing operation.
[0026] At magnet fixing position 2, the S pole and N pole of the magnet are stacked in a manner 5. Magnet 6 is assembled at magnet fixing position 2 in accordance with the S pole and N pole stacking method 5.
[0027] Circuit board 8 is a PCB board that integrates red LED, charging blue LED, discharging yellow LED and self-locking switch. Circuit board 8 is equipped with 670nm red LED 9 and charging blue LED and discharging yellow LED 10.
[0028] In the specific technical solution, the circuit board 8 serves as the core control and execution carrier, and the integrated 670nm red LED 9 is the red light emission source. When the circuit of the circuit board 8 is completed, the soft-pack lithium battery 7 supplies power to the 670nm red LED 9, triggering the 670nm red LED 9 to emit health-promoting red light in the 670nm band. At the same time, the device can adjust the wavelength of the red LED to the red light band range of 600-1000nm according to the usage requirements. The circuit board 8 adapts the electrical signal output of red LEDs in different bands to meet diverse red light health-promoting needs.
[0029] The diffuse reflector 12 is provided with a diffuse reflector convex mirror 13 and a diffuse reflector grid 14. When the diffuse reflector 12 is assembled, the mirror surface of the diffuse reflector convex mirror 13 is set upward, and the mirror surface of the diffuse reflector grid 14 is set downward and attached to the circuit board 8.
[0030] More specifically, the red light emitted by the 670nm red LED9 is directly projected onto the surface of the diffuse reflector grid 14 of the diffuse reflector plate 12. The diffuse reflector grid 14 first disperses and refracts the red light, and then the red light is transmitted to the diffuse reflector convex mirror 13 of the diffuse reflector plate 12. The diffuse reflector convex mirror 13 performs secondary homogenization on the dispersed red light, and the red light is formed into a uniform surface light source through convex refraction, avoiding the problem of light concentration caused by single-point light source illumination. The red light after double homogenization penetrates the transparent light-transmitting area of the light-transmitting mask 11 and is projected outward. The column of the light-transmitting mask 11 is sprayed with a white opaque coating to directionally constrain the light, ensuring that the red light is accurately projected onto the target area of care, and achieving uniform and gentle red light health care irradiation.
[0031] It should be noted that the aluminum alloy shell 1, magnet 6, soft-pack lithium battery 7, circuit board 8, diffuse reflector 12 and light-transmitting mask 11 are fixed by four studs to form a six-layer stacked overall structure.
[0032] In summary, the aluminum alloy shell 1 is an integral casting structure, serving as the foundation for all components. The internal magnet fixing position 2 is used to assemble the magnet 6. The magnet 6 is assembled strictly according to the stacking method 5 of the magnet's S pole and N pole, ensuring magnetic stability and enabling the use of the care device with magnetic accessories, expanding its application scenarios. The aluminum alloy shell 1 uses four studs to firmly connect the six-layer structure of magnet 6, soft-pack lithium battery 7, circuit board 8, diffuse reflector 12, and light-transmitting mask 11, which are stacked in sequence. The precise fitting and stacking of each component ensures the stability of each structure during operation, avoiding problems such as poor circuit contact and light projection deviation caused by vibration and shaking. At the same time, the compact stacking structure reduces the refraction loss of light inside the device, improving the red light projection efficiency.
[0033] Working principle of the 670nm red light health care device of this invention: The core working principle of this 670nm red light health care device revolves around three main aspects: power supply control, red light emission, and light homogenization projection. These components work together to achieve the red light health care function, while the compact structural design ensures stable operation. The specific working principle is described below: I. Power Supply and On / Off Control Principles The core power supply of the device is a soft-pack lithium battery 7, which is soldered to a circuit board 8 that integrates various electronic components to provide working power for the entire nursing device; the Type-C port 4 is embedded and connected to the circuit board 8, and external charging devices can replenish the power of the soft-pack lithium battery 7 through the Type-C port 4. During the charging process, the charging blue LED 10 on the circuit board 8 receives the electrical signal of the circuit board 8 and emits blue light to realize the visual indication of the charging status.
[0034] Power on / off control is achieved by the switch button 15 in conjunction with the self-locking switch on the circuit board 8. Pressing the switch button 15 with a reset spring triggers the self-locking switch on the circuit board 8, completing the switching of circuit on / off. After being pressed, the switch button 15 rebounds and resets through the built-in reset spring, ensuring the continuity of the pressing operation.
[0035] II. Principles of Red Light Emission and Wavelength Tuning Circuit board 8 serves as the core control and execution carrier, with an integrated 670nm red LED 9 as the red light emission source. When the circuit of circuit board 8 is completed, the soft-pack lithium battery 7 supplies power to the 670nm red LED 9, triggering the 670nm red LED 9 to emit health-promoting red light in the 670nm band. At the same time, the device can adjust the wavelength of the red LED to the red light band range of 600-1000nm according to the usage requirements. Circuit board 8 adapts the electrical signal output of red LEDs in different bands to meet diverse red light health-promoting needs.
[0036] III. Principles of Light Uniformation and Projection The red light emitted by the 670nm red LED9 is directly projected onto the surface of the diffuse reflector grid 14 of the diffuse reflector plate 12. The diffuse reflector grid 14 first disperses and refracts the red light, and then the red light is transmitted to the surface of the diffuse reflector convex mirror 13 of the diffuse reflector plate 12. The diffuse reflector convex mirror 13 performs secondary homogenization on the dispersed red light, and the red light is formed into a uniform surface light source through convex refraction, avoiding the problem of light concentration caused by single-point light source illumination. The red light after double homogenization penetrates the transparent light-transmitting area of the light-transmitting mask 11 and is projected outward. The column of the light-transmitting mask 11 is sprayed with a white opaque coating to directionally constrain the light, ensuring that the red light is accurately projected onto the target area of care, and achieving uniform and gentle red light health care irradiation.
[0037] IV. Auxiliary Working Principle of Equipment Structure The aluminum alloy shell 1 is an integral casting structure, serving as the foundation for all accessories. The magnet fixing position 2 inside is used to assemble the magnet 6. The magnet 6 is assembled strictly according to the stacking method 5 of the magnet's S pole and N pole to ensure magnetic stability. This allows the care device to be used in conjunction with magnetic accessories, expanding the application scenarios. The aluminum alloy shell 1 is fastened to the six-layer structure of magnet 6, soft-pack lithium battery 7, circuit board 8, diffuse reflector 12, and light-transmitting mask 11 by four studs. The precise fitting and stacking of each accessory ensures the stability of each structure during operation, avoiding problems such as poor circuit contact and light projection deviation caused by vibration and shaking. At the same time, the compact stacking structure reduces the refraction loss of light inside the device, improving the red light projection efficiency.
