[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] It should be noted that in the description of this utility model, if the terms "first" or "second" appear, they are only used for the convenience of describing different components or names, and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, if "and / or" appears throughout the text, it means that it includes three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B.
[0040] Please refer to the reference. Fig. 1 to Fig. 5 This utility model embodiment proposes a handheld phototherapy device 100, which includes: a handle shell 10, a phototherapy head 20, a first light-emitting element 30, and a second light-emitting element 40; the handle shell 10 is for the user to hold; the phototherapy head 20 is disposed at one end of the handle shell 10, and the phototherapy head 20 has a first light-transmitting surface 21 and a second light-transmitting surface 22 disposed opposite to each other; the first light-emitting element 30 and the second light-emitting element 40 are located inside the handle shell 10 or the phototherapy head 20, the first light-emitting element 30 emits light facing the first light-transmitting surface 21, and the second light-emitting element 40 emits light facing the second light-transmitting surface 22.
[0041] For the conventional light therapy instrument 100 which only emits light from one surface, the user has to find the light-emitting surface and align it with the skin, especially when switching to another skin area for light therapy, for example, switching the light therapy instrument 100 from the left face to the right face, the user needs to adjust the angle again to ensure that the light-emitting surface is aligned with the skin.
[0042] However, in the embodiment of the utility model, both opposite surfaces of the light therapy instrument 100 can emit light, so the user can use any one of the light-transmitting surfaces for light therapy when using, without fixing the use of a certain surface, so that the use is more flexible and limited. Especially for this handheld light therapy instrument 100, when the user changes the left and right hand to hold the handle shell 10, there is no need to adjust the angle of the handle shell 10, that is, no matter the user holds the handle shell 10 normally or reversely, one of the light-transmitting surfaces can still face the skin, thereby having great convenience for use and being more in line with the user's habit and demand.
[0043] In some embodiments, the light therapy head 20 is flat, the first light-transmitting surface 21 and the second light-transmitting surface 22 are spaced apart along the thickness direction of the light therapy head 20, and the distance between the first light-transmitting surface 21 and the second light-transmitting surface 22 gradually decreases in the direction away from the handle shell 10. In this embodiment, the first light-transmitting surface 21 and the second light-transmitting surface 22 are surfaces of the light therapy head 20 with a larger area, so they have a larger light therapy area and can cover more skin areas. In addition, the flat light therapy head 20 can have a smaller volume while having a larger light therapy area, so it is lighter and easier to hold.
[0044] In some embodiments, the width of the light therapy head 20 gradually increases in the direction away from the handle shell 10, for example, the lower end is the end where the handle shell 10 is located, and the upper end is the end where the light therapy head 20 is located, so the light therapy head 20 has a shape of being narrow at the lower end and wide at the upper end. Alternatively, the upper end of the light therapy head 20 has a shape of being low in the middle and high at both ends, so the entire light therapy head 20 has a fish tail shape. When the light therapy head 20 adopts a relatively soft plastic structure, the light therapy head 20 can have elastic deformation, such as being bent, so as to better adapt to the change of the skin curvature.
[0045] Of course, in other embodiments, the light therapy head 20 can also have other shapes, such as square, triangular, circular, etc.
[0046] In the embodiment of the utility model, the first light emitting part 30 and the second light emitting part 40 can be arranged at the connecting position of the handle shell 10 and the light therapy head 20, or arranged in the light therapy head 20, or arranged in the handle shell 10. In a specific embodiment, the first light emitting part 30 and the second light emitting part 40 are arranged in the interior of the handle shell 10 and located at the upper end of the handle shell 10, and the handle shell 10 is provided with a light transmission hole 11 corresponding to the first light emitting part 30 and the second light emitting part 40, and the light therapy head 20 is sleeved at the upper end of the handle shell 10 and covers the light transmission hole 11.
[0047] In some embodiments, the first light emitting part 30 comprises a first lamp plate 31 and a first light emitting unit 32 fixed on the first lamp plate 31, and the second light emitting part 40 comprises a second lamp plate 41 and a second light emitting unit 42 fixed on the second lamp plate 41; the first lamp plate 31 is parallel to the first light transmission surface 21, and the second lamp plate 41 is parallel to the second light transmission surface 22. Wherein, parallel means parallel or substantially close to parallel, and the light emitting unit means LDE lamp, which can emit red light, infrared light, blue light and purple light to enable light therapy. In the embodiment, the first lamp plate 31 and the second lamp plate 41 are also arranged at an included angle, and the upper ends of the first lamp plate 31 and the second lamp plate 41 are close to each other, and the lower ends are away from each other.
[0048] Further, the light therapy instrument 100 further comprises two micro-current electrodes 50 and a circuit board 61 electrically connected with the micro-current electrodes 50, and the micro-current electrodes 50 are fixed with the light therapy head 20. When the micro-current electrodes 50 contact the skin, the skin acts as an electrical conductor, so that the skin, the two micro-current electrodes 50 and the circuit board 61 form a closed loop, and the micro-current electrodes 50 act as discharge electrodes to stimulate the skin with micro-current. Since the micro-current electrodes 50 are arranged in the light therapy head 20, they are close to the position of light therapy, so they can be used in combination with light therapy to improve the effect of skin physiotherapy.
[0049] The shape of the micro-current electrode 50 is not limited, as long as it is a good electrical conductor, such as a metal contact, a metal column, a metal sheet or a metal block.
[0050] Please refer to Fig. 7 and Fig. 8In some embodiments, the light therapy head 20 comprises a first end 23 and a second end 24 arranged oppositely, the first end 23 is connected with the handle housing 10, and the first light-transmitting surface 21 and the second light-transmitting surface 22 extend from the first end 23 to the second end 24 respectively. Two micro-current electrodes 50 are fixed to the second end 24, the micro-current electrodes 50 have proximal ends 51 and distal ends 52, the proximal ends 51 of the two micro-current electrodes 50 are close to each other and close to the second end 24 relative to the distal ends 52, and the distal ends 52 are away from each other. In this way, the end (proximal end 51) of the two micro-current electrodes 50 close to each other is arranged lower, and the end (distal end 52) of the two micro-current electrodes 50 away from each other is arranged higher, so that the upper end of the whole light therapy instrument 100 presents a shape of middle low and left and right sides high, thereby being more consistent with the curvature of the human face.
[0051] In some embodiments, the micro-current electrode 50 is in the shape of a long strip in the direction from the proximal end 51 to the distal end 52, and the micro-current electrode 50 further has a contact surface 53, the contact surface 53 is connected with the proximal end 51 and the distal end 52 respectively on both sides, the contact surface 53 is away from the second end 24, and the contact surface 53 is an arc surface or an inclined surface. In this embodiment, the contact surface 53 refers to the upper surface, and the contact surface 53 directly contacts the skin when the micro-current stimulation is performed. When the contact surface 53 is an arc surface, the arc surface can be an arc with a fixed curvature, or the arc surface is formed by sequentially connecting a plurality of arc segments with different curvatures.
[0052] Further, the light therapy instrument 100 further comprises two conductive strips 62, one end of the two conductive strips 62 is connected with the two micro-current electrodes 50 one by one, and the other end of the two conductive strips 62 is further electrically connected with the circuit board 61. The light therapy head 20 is a transparent plastic part, the micro-current electrode 50, the conductive strip 62 and the light therapy head 20 are integrally injection molded. In this embodiment, the micro-current electrode 50 and the conductive strip 62 are inserts, and the light therapy head 20 is integrally injection molded to the micro-current electrode 50 and the conductive strip 62, thereby avoiding the micro-current electrode 50 and the conductive strip 62 from being separated.
[0053] Please refer to Fig. 9 and Fig. 10 In order to enhance the bonding force of the micro-current electrode 50 and the light therapy head 20, the lower surface of the micro-current electrode 50 is provided with one or more engagement grooves 54. When the light therapy head 20 in a molten state is combined with the micro-current electrode 50, part of the light therapy head 20 is embedded in the engagement groove 54, so that after the light therapy head 20 is shaped, an engagement protrusion 25 is formed on the second end 24, the engagement protrusion 25 is engaged with the engagement groove 54, thereby increasing the contact area of the micro-current electrode 50 and the light therapy head 20, and making the connection of the two more firm.
[0054] Most of the conductive strip 62 is embedded in the light therapy head 20, only the upper and lower ends of the conductive strip 62 are exposed in the light therapy head 20 to facilitate electrical connection with the relevant electronic elements.
[0055] When the light therapy head 20 is a transparent plastic part, the entire light therapy head 20 is light-transmitting, and the part of the light therapy head 20 that is not blocked by other structures can transmit light outward for light therapy, so the light therapy head 20 has more light therapy areas.
[0056] Please refer to Fig. 11 to Fig. 14 Further, the light therapy instrument 100 further comprises a first support 70, a second support 80 and a circuit board 61, the first support 70 and the second support 80 are located in the handle shell 10 and are spaced apart along the length direction of the handle shell 10. In a specific embodiment, the first support 70 is located above the second support 80.
[0057] The first support 70 is provided with a first slot 71, the second support 80 is provided with a second slot 81, the first slot 71 and the second slot 81 are oppositely arranged, one end of the circuit board 61 is inserted into the first slot 71, and the other end of the circuit board 61 is inserted into the second slot 81. In this way, the upper and lower ends of the circuit board 61 are fixed by the upper and lower supports, and the middle part of the circuit board 61 is not blocked by the support, which is conducive to heat dissipation of the circuit board 61.
[0058] The second support 80 is fixed with the handle shell 10, so the first support 70 can not be fixed with the handle shell 10, but only supported by the circuit board 61 and the second support 80. Of course, the first support 70 can also abut against the handle shell 10 to limit upward movement of the first support 70.
[0059] In the embodiment, the first light emitting part 30 and the second light emitting part 40 are fixed to the first support 70, specifically, the first support 70 is provided with two limiting protrusions 72, and the first lamp plate 31 and the second lamp plate 41 are each provided with a limiting recess (not marked) and are respectively inserted with one limiting protrusion 72.
[0060] Please refer to Fig. 6 and Fig. 11 Further, the light therapy instrument 100 further comprises two conductive parts 63 and a charging module 64, one end of the conductive part 63 is exposed to the handle shell 10 or the light therapy head 20, the other end of the conductive part 63 is further electrically connected with the charging module 64, the charging module 64 is electrically connected with the circuit board 61, and the two conductive parts 63 and the charging module 64 are connected to form a charging circuit. Therefore, the two conductive parts 63 serve as positive and negative electrodes for charging the battery 67 in the handle shell 10.
[0061] Specifically, the conductive member 63 can be a conductive spring, a conductive contact, a conductive sheet, etc. In a specific embodiment, one conductive member 63 is in a column shape, and the other conductive member 63 is in a ring shape and surrounds the column-shaped conductive member 63.
[0062] The conductive member 63 can be arranged on the handle housing 10 or the light therapy head 20. When the conductive member 63 is arranged on the handle housing 10, the conductive member 63 can be fixed on the bottom of the handle housing 10. When the bottom of the handle housing 10 is inserted into the charging base 200, the conductive member 63 on the bottom can be directly used for charging.
[0063] In some embodiments, the handle housing 10 is further provided with a skin detection module 65, and the other end of the conductive member 63 is further electrically connected with the skin detection module 65, and the two conductive members 63 and the skin detection module 65 are connected to form a skin detection circuit. In this embodiment, the conductive member 63 serves as a detection probe, such as a capacitive probe or a resistive probe. When the oil and water on the surface of the skin respectively contact the two conductive members 63, due to the different specific gravity, dielectric constant and morphology of the oil and water, the capacitance value or the resistance value will change. This change is captured by the detection probe and converted into an electrical signal output, thereby realizing the detection of the oil and water content. In this embodiment, the conductive member 63 can detect the skin state, so that the user can select appropriate skin care products according to the detection result.
[0064] Since the skin is a conductor, when the two conductive members 63 contact the skin, the skin detection circuit and the skin together form a closed loop.
[0065] In the embodiment of the utility model, the charging and the skin detection share the conductive member 63, which reduces the arrangement of the conductive member 63 and is beneficial to the simplification of the structure and the reduction of the cost.
[0066] Further, the light therapy instrument 100 further comprises a wireless communication module 66, and the wireless communication module 66 is fixed with the handle housing 10. The wireless communication module 66 is a Bluetooth module, an NFC module or other wireless communication modes. The wireless communication module 66 is electrically connected with the skin detection module 65, and can send relevant information, such as the skin information collected by the conductive member 63, to a terminal such as a mobile phone or a computer.
[0067] The charging module 64, the skin detection module 65 and the wireless communication module 66 in the above can be fixed on the circuit board 61.
[0068] It should be finally pointed out that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been explained in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement to part of the technical features; and these modifications or replacements do not drive the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
