For ordinary skilled persons in the art, the specific meaning of the above terms in the embodiments of the utility model can be understood according to the specific circumstances.
[0044] According to one embodiment of the utility model, referring to Figures 1-4 The hand-held light therapy instrument provided by the utility model includes a handle part 1 and a light therapy part 2. The handle part 1 includes a first shell 3 and a circuit board 4 arranged in the first shell 3. The light therapy part 2 includes a second shell 5 and a light therapy assembly 6. The second shell 5 is connected to one end of the first shell 3, and a light-transmitting hole 7 is arranged at the end of the second shell 5 away from the first shell 3. The light therapy assembly 6 includes a convex lens 8 and a lamp panel 9 arranged in the second shell 5. The convex lens 8 is arranged at the light-transmitting hole 7, and the lamp panel 9 is arranged opposite to the convex lens 8 and is electrically connected to the circuit board 4.
[0045] In the embodiment of the utility model, the first shell 3 of the handle part 1 serves as a shell, which can protect the internal elements from the external environment and provide a holding feeling for the user, facilitating the user to carry it. The circuit board 4 is responsible for controlling the function operation of the entire device, including power management, light therapy mode, light intensity adjustment and the like.
[0046] The second shell 5 can be connected to the top end of the first shell 3, forming the main light-emitting area of the light therapy instrument. The second shell 5 is provided with a light-transmitting hole 7 at the end away from the handle part 1, for allowing light to pass through.
[0047] The convex lens 8 is placed at the light-transmitting hole 7, which focuses the light emitted by the lamp panel 9, so that the light is more concentrated on the target position, thereby enhancing the phototherapy effect and improving the light utilization rate.
[0048] The lamp panel 9 is a core component for generating light of a specific wavelength, which is arranged at a position opposite to the convex lens 8 and can be connected to the circuit board 4 in the handle part 1 through an electric wire. According to different phototherapy requirements, the lamp panel 9 can contain different types of LED lamp beads (such as red light, blue light, infrared light, etc.) to emit light of corresponding wavelengths to achieve specific physiological effects.
[0049] After the user starts the handheld phototherapy instrument, the circuit board 4 controls the lamp panel 9 to emit light of different wavelengths, and when the generated light passes through the convex lens 8 at the light-transmitting hole 7, the light is focused to form a more concentrated light spot, which helps to improve the light density on the local skin area and thereby enhances the phototherapy effect. The focused light penetrates the epidermis to reach deeper tissues, which can stimulate cell activity, promote blood circulation, and accelerate wound healing, etc., and the specific effect depends on the properties (such as wavelength) of the used light.
[0050] Therefore, the handheld phototherapy instrument provided by the embodiment of the present application realizes miniaturization while ensuring good phototherapy effect through optimized structure design.
[0051] According to one embodiment of the present application, as shown in Figure 2 The plane where the light-transmitting hole 7 of the second shell 5 is located has an included angle a with the central axis of the first shell 3, and the included angle a is an acute angle.
[0052] Specifically, the second shell 5 can be a curved member, thereby forming the included angle a, for example, 10°, 20°, 30°, 45°, 60°, etc., which can make the light from the convex lens 8 irradiate the user's skin at a more ergonomic angle, so that the device can be used in a more natural and comfortable handheld posture, which can reduce the pressure on the wrist and arm and improve the comfort of use.
[0053] According to one embodiment of the present application, as shown in Figures 3-5 The inner wall of the second shell 5 is provided with a first positioning groove 10 and a second positioning groove 11; the side of the lamp panel 9 facing the convex lens 8 is electrically connected with a lamp bead 12, and the edge of the lamp panel 9 is provided with a first positioning part 13 which is clamped in the first positioning groove 10; the convex lens 8 includes a light-emitting part 14 and a second positioning part 15, the light-emitting part 14 corresponds to the lamp bead 12, and the second positioning part 15 is arranged at the edge of the light-emitting part 14 and is clamped in the second positioning groove 11.
[0054] Specifically, by clamping the first positioning part 13 of the lamp panel 9 into the first positioning groove 10 and clamping the second positioning part 15 of the convex lens 8 into the second positioning groove 11, unnecessary displacement of these key components during use can be effectively prevented, and the stability of the internal structure of the device is ensured.
[0055] It can be understood that the accurate and stable alignment between the lamp beads 12 on the lamp panel 9 and the light emitting part 14 of the convex lens 8 is the key to achieving efficient light collection. Through the design of the positioning structure, it can be ensured that the light emitted by each lamp bead 12 can be effectively focused by the light emitting part 14 of the convex lens 8, thereby improving the light therapy effect.
[0056] According to an embodiment of the present application, as shown in Figure 3 , the second shell 5 can be a split structure. Specifically, the second shell 5 includes a first shell 16 and a second shell 17 that are spliced together, which facilitates the installation of the convex lens 8 and the lamp panel 9.
[0057] According to an embodiment of the present application, as shown in Figure 3 , the number of lamp beads 12 is multiple, and each lamp bead 12 includes multiple lamp filaments for emitting light of different wavelengths.
[0058] Specifically, since each lamp bead 12 has the ability to emit multiple wavelengths of light, users can choose or combine different wavelengths of light for personalized treatment according to their needs. This makes the device more flexible and can adapt to a wider range of user needs. And by integrating multiple different lamp filaments into a single lamp bead 12, the overall structure can be more compact, facilitating miniaturization design, which is particularly important for handheld devices.
[0059] For example, the lamp panel 9 includes three LED lamp beads, each containing three lamp filaments that can emit red light, blue light, and infrared light, i.e., having three light therapy modes. Among them, red light can stimulate collagen production, improve skin elasticity, and reduce fine lines; blue light can be used to treat acne as it can help kill bacteria that cause acne; infrared light helps promote blood circulation, speeds up wound healing, and reduces inflammation.
[0060] It can be understood that multiple lamp filaments can work at the same time, which means that multiple wavelengths of light can be used simultaneously for comprehensive treatment of the skin during a treatment session, thereby improving treatment efficiency and effectiveness.
[0061] According to an embodiment of the present application, as shown in Figure 1 and Figure 3As shown, the lamp bead 12 includes an infrared lampwick, and an indicator light 18 is electrically connected on the circuit board 4, which is used to indicate the infrared light emitted by the infrared lampwick of the lamp bead 12; and a light guide shell 19 corresponding to the indicator light 18 is arranged on the first shell 3.
[0062] Specifically, since the infrared light is invisible to the human eye, the user cannot directly observe whether the infrared light is working. Through the design of the indicator light 18 and the light guide shell 19, when the device is in the infrared light mode, the indicator light 18 can emit visible light such as green light and transmit it to the user through the light guide shell 19, so that the user can clearly know that the current is infrared light therapy, and ensure that the required light therapy mode is correctly selected, avoiding invalid treatment caused by misoperation.
[0063] Moreover, the indicator light 18 is hidden in the handle part 1 and displayed through the light guide shell 19, which not only maintains the integrity and simplicity of the appearance of the device, but also provides necessary functional information. Such a design is generally more beautiful than directly installing the indicator light 18 on the shell.
[0064] Therefore, the embodiment of the utility model improves the user experience and increases the safety and reliability of use by setting the indicator light 18 and the light guide shell 19. Such a design enables the user to use the device more conveniently and accurately, and also enables the user to better understand and control the light therapy process.

[0066] Specifically, the flexible sheath 20 can be made of soft glue material, and the flexible sheath 20 can provide a variety of color and texture choices, thereby improving the overall appearance of the device. The user can replace the sheath of different styles according to personal preferences, increasing the personalized elements of the product.
[0067] Moreover, the flexible sheath 20 can effectively prevent scratches or wear of the second shell 5 due to daily use, and can also provide a certain degree of waterproof and dustproof function, prolonging the service life of the device.
[0068] In addition, the opening 21 at the end of the flexible sheath 20 corresponds to the light transmission hole 7 on the second shell 5 accurately, ensuring that the light can pass without obstacles and will not affect the light therapy effect.
[0069] According to one embodiment of the utility model, the second shell 5 can be a hard material.
[0070] In particular, the hard material such as plastic, metal, etc. can provide good structural strength and durability, which makes the shell of the phototherapy part 2 more solid and less likely to be deformed or damaged.
[0071] According to an embodiment of the present application, referring to Figure 3 and Figure 4 , the handle part 1 further comprises a mounting rack 22, which is adaptively arranged in the first shell 3, and the circuit board 4 is mounted on the mounting rack 22, and one end of the mounting rack 22 is connected with the second shell 5.
[0072] In this embodiment of the present application, the mounting rack 22 provides a stable mounting platform for the circuit board 4, ensuring that the circuit board 4 will not loosen or shift during use, thereby ensuring reliable operation of the device.
[0073] In addition, the top end of the mounting rack 22 is provided with a clamping groove 23, and the bottom of the second shell 5 is provided with a clamping protrusion 24, which is clamped in the clamping groove 23, realizing the stable connection of the mounting rack 22 and the second shell 5, and the structure of the whole device becomes more compact and integrated. This not only improves the overall stability of the device, but also makes the assembly process simpler.
[0074] In addition, the mounting rack 22 can be a hard material made of a material with certain rigidity, such as hard plastic, which can increase the structural strength of the handle part 1, prevent deformation or damage during use, and improve the service life of the device.
[0075] According to an embodiment of the present application, referring to Figure 1 and Figure 3 , the circuit board 4 is electrically connected with a button 25, the mounting rack 22 is provided with a button cap 26 corresponding to the button 25, and the first shell 3 is provided with a through hole 27 for the button cap 26 to pass through.
[0076] In particular, the mounting rack 22 is provided with a mounting hole, and the button cap 26 is arranged in the mounting hole and passes through the through hole 27 on the first shell 3, which can facilitate the user to press, thereby triggering the button 25 to directly operate the device, such as turning on and off, adjusting different light therapy modes, etc. without complex operation steps, improving the user's experience.
[0077] According to an embodiment of the present application, referring to Figure 1 and Figure 3 , the handle part 1 further comprises a charging battery 28 and a charging interface 29, the charging battery 28 is mounted on the mounting rack 22 and electrically connected to the circuit board 4, and the charging interface 29 is electrically connected to the circuit board 4, and the charging interface 29 is arranged at the other end of the mounting rack 22 away from the second shell 5.
[0078] Specifically, in order to ensure that the charging battery 28 will not be loose or displaced during use, a special battery slot or fixing clamp can be designed on the mounting rack 22.
[0079] The bottom end of the mounting rack 22 is provided with a plug interface 30, and the charging interface 29 can be a Type-C interface and is located in the plug interface 30 of the mounting rack 22. The user can connect to the charging interface 29 through the USB line or other standard charging line through the plug interface 30 to charge the device, which is convenient and fast.
[0080] The embodiment of the utility model makes the device not need to rely on external power supply through the built-in charging battery 28, and the user can use the device more conveniently, which effectively improves the portability of the device.
[0081] According to an embodiment of the utility model, referring to Figure 3 and Figure 6 , a sealing ring 31 is arranged between the first shell 3 and the other end of the mounting rack 22 away from the second shell 5.
[0082] Specifically, the bottom end of the mounting rack 22 is provided with a sealing groove 32, and the sealing groove 32 is provided with a sealing ring 31.

[0083] According to an embodiment of the utility model, referring to Figures 1-4 , the first shell 3 is flat, and correspondingly, the mounting rack 22 is also flat.
[0084] Specifically, the flat design is more in line with the ergonomic principle, making the user hold it more naturally and comfortably. The flat handle 1 can better fit the palm, reducing hand fatigue.
[0085] In addition, the flat design can make the device more compact, convenient to carry and store. The user can easily put the device into a bag or pocket and use it anytime and anywhere.
[0086] According to an embodiment of the utility model, the first shell 3 is a metal piece.
[0087] Specifically, the metal material has high strength and hardness, which can better resist external impact and wear and tear, prolong the service life of the device, and improve the overall quality of the product.
[0088] In addition, the metal surface can provide smooth or delicate touch after appropriate treatment, increasing the user's comfort.
