[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0036] In addition, if the embodiments of the utility model involve descriptions of "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B schemes. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those skilled in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0037] As Figures 1 to 4 As shown in the utility model discloses a kind of patch type phototherapy instrument components, the patch type phototherapy instrument component includes patch 1, control box 2 and charging wire 3, the control box 2 is used to control the patch of patch type phototherapy instrument component, the charging wire 3 is used to charge control box 2.

[0038] Specifically, patch 1 includes an outer patch layer and an inner patch layer, with a circuit board between the outer and inner patches. The circuit board contains multiple phototherapy LED beads. The outer patch layer is an opaque outer layer made of solid-color flexible material, while the inner patch layer is a light-transmitting inner layer made of transparent flexible material. When in use, the light emitted by the phototherapy LED beads passes through the inner patch layer and shines onto the user's skin.

[0039] Specifically, the outer layer of the patch has two charging electrodes 11, and the control box 22 has two magnetic electrodes 21. The two magnetic electrodes 21 can be magnetically connected to the two charging electrodes 11 on the patch 1 respectively and achieve electrical conduction.

[0040] Furthermore, the control box 22 is detachably connected to the patch 1. The detachable design allows users to replace the patch 1 with different shapes, or replace the patch 1 with a new patch 1 if it is damaged, which reduces the replacement cost.

[0041] Specifically, the structure of the charging cable 3 is described in the following embodiments. It is worth noting that since the patch-type phototherapy device assembly adopts all the technical solutions of all the embodiments of the charging cable 3 described below, it possesses at least all the beneficial effects brought about by the technical solutions of the following embodiments, which will not be elaborated upon here.

[0042] This application also proposes a charging cable 3, such as Figures 2 to 9 As shown, the charging cable 3 includes a wire harness 31, a power interface 32, and a charging interface 33.

[0043] Specifically, the wiring harness 31 is a flexible wire structure used to connect the power interface 32 and the charging interface 33 to achieve current transmission. The power interface 32 is located at one end of the wiring harness 31, and this power interface 32 is used to connect an external power source to the charging cable 3, ensuring that the charging cable 3 can obtain power from the external power source.

[0044] Alternatively, the power interface 32 can be a USB-A interface, a Type-C interface, a DC interface, or other interface types compatible with power adapters.

[0045] Alternatively, the external power source can be a power adapter, power bank, tablet computer, laptop computer, car power supply, etc.

[0046] Specifically, the charging interface 33 is located at the other end of the wiring harness 31. The charging interface 33 includes a housing 331, a charging structure 332, and a trigger 335. The housing 331 is used to support and fix the charging structure 332 and the trigger 335 to ensure stability during charging.

[0047] The charging structure 332 is arranged on the shell 331 and exposed from the surface of the shell 331, for being magnetically connected with the magnetic electrode 21 of the control box 2 and conducting to charge the control box 2. Specifically, the charging structure 332 includes two first terminals 332a arranged at intervals, which are respectively attracted to and conducted with the two magnetic electrodes 21 of the control box 2, thereby charging the control box 2. Herein, since the magnetic electrode 21 of the control box 2 has magnetism, the first terminal 332a can be attracted to the magnetic electrode 21. In this way, the automatic alignment and magnetic connection of the first terminal 332a and the magnetic electrode 21 can be achieved, thereby ensuring stable current conduction and simplifying the connection mode of the charging wire 3 and the control box 2, so as to simplify the charging mode of the control box 2.

[0048] Alternatively, the two first terminals 332a are made of passive magnetic materials. The passive magnetic materials generally refer to materials with good magnetic permeability, such as iron, nickel, soft magnetic alloy, nickel-iron alloy or other magnetic metals. These materials do not have permanent magnetism by themselves, but can be induced by an external magnetic field and produce temporary magnetism. Since the passive magnetic material does not actively generate a magnetic field, the use of passive magnetic material to make the two first terminals 332a can ensure the magnetic attraction reliability of the first terminals 332a and the magnetic electrode 21 (usually a permanent magnetic material) of the control box 2, while effectively reducing the magnetic interference that the first terminals 332a may cause to other elements (such as the trigger 335 or the circuit board 336) inside the charging interface 33.

[0049] Alternatively, the first terminal 332a is made of permanent magnet material. The permanent magnet material has long-term stable magnetism, such as neodymium iron boron (NdFeB), ferrite and samarium cobalt (SmCo), etc. These materials can generate a continuous magnetic field and are suitable for use as active magnetic components in magnetic connection. In this way, on the one hand, the stability of the connection between the charging interface 33 and the control box 2 can be further enhanced, and on the other hand, the alignment and attraction of the first terminal 332a and the magnetic electrode 21 are more convenient.

[0050] Of course, the design of the present application is not limited thereto, and in some embodiments, the charging structure 332 is not limited to the form of the first terminal 332a, and can also be arranged in the form of a pin, a contact or the like.

[0051] The trigger 335 is arranged on the shell 331 and is used to trigger the sensor 23 of the control box 2. The control box 2 is arranged to sense the connection state of the charging interface 33 according to the signal of the sensor 23.

[0052] Specifically, when the charging interface 33 is connected to the control box 2, the trigger piece 335 generates a force (e.g. magnetic force, mechanical stress) to trigger the sensor 23 of the control box 2, so that the sensor 23 detects the connection state of the charging interface 33 and sends a first electrical signal to the control module of the control box 2. After receiving the first electrical signal, the control module automatically switches to the charging mode, so that the magnetic suction electrode 22 undertakes the charging task to transfer the current from the charging interface 33 to the internal power supply of the control box 2, thereby realizing the charging function of the control box 2.

[0053] When the control box 2 is disconnected from the charging interface 33, the sensor 23 detects the state change and sends a second electrical signal to the control module due to the disappearance of the force of the trigger piece 335. After receiving the second electrical signal, the control module automatically switches from the charging mode to the power supply mode, and at this time the function of the magnetic suction electrode 22 changes to supply power from the control box 2 to the patch 1.

[0054] Through this design, the control box 2 can automatically switch between the charging mode and the power supply mode according to the detection of the sensor 23 on the trigger piece 335. This not only realizes the intelligent switching of the charging mode and the power supply mode of the control box 2, avoids the conflict between the two modes, thereby effectively protecting the circuit of the control box 2, avoiding the function disorder or damage caused by incorrect operation, improving the stability and reliability of the control box 2, and making the control box 2 no longer need to design an additional charging interface 33.

[0055] In addition, the sensor 23 can be configured to detect the trigger piece 335 only when the charging interface 33 is completely connected, so as to ensure that the control box 2 can recognize the stable connection state and avoid the false charging caused by virtual connection or misalignment, thereby increasing the reliability of the connection between the control box 2 and the charging interface 33.

[0056] Alternatively, the sensor 23 is configured as a Hall sensor, and correspondingly, the trigger piece 335 is configured as a magnetic piece.

[0057] Specifically, the Hall sensor can detect the change of the magnetic field caused by the magnetic piece. When the charging interface 33 is connected to the control box 2, the magnetic field generated by the magnetic piece is sensed by the Hall sensor, thereby triggering the sensor to send a first electrical signal to the control module of the control box. When the control box 2 is disconnected from the charging interface 33, the magnetic field generated by the magnetic piece disappears or changes, and the Hall sensor detects this change and sends a second electrical signal to the control module.

[0058] Through the combination of the Hall sensor and the magnetic piece, the sensor 23 and the trigger piece 335 can realize contactless and frictionless triggering, thereby helping to improve the durability of the charging line 3 and the control box 2. Moreover, this combination also helps to simplify the structural design of the charging line 3 and the control box 2, avoiding the design of an additional physical button.

[0059] Of course, the design of the present application is not limited thereto, in other embodiments, the sensor 23 of the control box 2 can also be provided as a pressure sensor, an infrared sensor, etc., and the trigger piece 335 is designed according to the triggering principle of the sensor 23.

[0060] Alternatively, the magnetic piece (i.e. the trigger piece 335) can be provided as a permanent magnet, or can be provided as an electromagnet.

[0061] It can be understood that the charging wire 3 of the technical solution of the present application is magnetically connected and conducted with the magnetic electrode 21 on the control box 2 through the charging structure 332, and the sensor 23 of the control box 2 is triggered by the trigger piece 335, so that the control box 2 can automatically switch between the charging mode and the power supply mode according to the signal of the sensor 23, and then in the power supply mode, the control box 2 can be charged through the charging structure 332.

[0062] In this way, not only the connection process of the traditional plug-in charging mode is omitted, but also the convenience of charging the control box 2 is significantly improved. Moreover, the control box 2 does not need to be charged through the additional charging interface 33, which can also simplify the circuit structure of the control box 2 and reduce the demand for additional interface components on the control box 2, thereby simplifying the structure and material cost of the control box 2.

[0063] In addition, the magnetic attraction connection mode of the charging structure 332 of the charging interface 33 and the magnetic electrode 21 of the control box 2 also helps to improve the convenience and stability of the connection of the charging interface 33 and the control box 2, and the reliability of the charging of the control box 2.

[0064] It can be seen that compared with the traditional plug-in charging mode, the charging wire 3 of the technical solution of the present application has the advantages of simplifying the charging mode of the control box 2, high charging reliability, simplifying the circuit structure of the control box 2, etc.

[0065] In some embodiments, the trigger piece 335 is spaced apart from the two first terminals 332a, and the connection lines of the trigger piece 335 and the two first terminals 332a are arranged at an angle. That is to say, the trigger piece 335 and the two first terminals 332a are not arranged on the same straight line.

[0066] This design can effectively avoid electromagnetic interference between the trigger piece 335 and the first terminal 332a, so as to ensure that the magnetic field of the trigger piece 335 can accurately act on the sensor 23 area of the control box 2, thereby improving the sensing accuracy of the control box 2 and the reliability of mode switching.

[0067] In addition, this angle design reasonably utilizes the space in the shell 331, so that the trigger piece 335 and the first terminal 332a are distributed at different positions of the shell 331, avoiding that the charging interface 33 is too long or too wide.

[0068] In some embodiments, the shell 331 comprises a panel 331a and a surrounding plate 331e connected to the panel 331a, and the panel 331a and the surrounding plate 331e form a receiving cavity 331c. The charging interface 33 further comprises a circuit board 336 disposed in the receiving cavity 331c, and the circuit board 336 is electrically connected to the wire harness 31 and the first terminal 332a.

[0069] Specifically, the wire harness 31 extends into the receiving cavity 331c and is electrically connected to the circuit board 336, and the first terminal 332a is mounted on the circuit board 336 by welding.

[0070] Specifically, the panel 331a is provided with two positioning holes 331d which pass through the panel 331a and communicate with the receiving cavity 331c. The two first terminals 332a are mounted on the circuit board 336 and respectively inserted into the two positioning holes 331d, and the ends of the two first terminals 332a respectively exposed on the outer surface of the panel 331a through the two positioning holes 331d.

[0071] In this way, the position of the first terminal 332a can be accurately limited through the positioning hole 331d, ensuring that the docking position of the first terminal 332a with the magnetic electrode 21 of the control box 2 is accurate, and avoiding the problem of poor contact caused by misalignment. Secondly, the positioning hole 331d can provide additional physical support for the first terminal 332a, making the first terminal 332a more stable, thereby preventing loosening or displacement due to external forces during long-term use and improving the durability of the charging interface 33.

[0072] At the same time, the first terminal 332a is mounted on the circuit board 336, and multiple fixation is achieved through the cooperation of the circuit board 336 and the positioning hole 331d, which not only simplifies the installation process of the terminal, but also reduces the additional fixing structure, thereby reducing the manufacturing cost and complexity.

[0073] In some embodiments, the panel 331a is further provided with a limiting hole 331b, and the trigger piece 335 is mounted in the limiting hole 331b. By mounting the trigger piece 335 in the limiting hole 331b, not only can the installation position and direction of the trigger piece 335 be limited, but also the magnetic pole direction of the trigger piece 335 can be limited, to ensure that the trigger piece 335 can accurately trigger the Hall sensor of the control box 2. Thus, it can be ensured that the Hall sensor receives stable and correct magnetic field signals, thereby improving the reliability of the charging interface 33 and the control box 2 during mode switching.

[0074] In addition, by designing the limiting hole 331b, the trigger piece 335 can be as close as possible to the outer surface of the shell 331. This close layout can effectively enhance the magnetic field strength of the trigger piece 335, so that the Hall sensor in the control box 2 can respond more sensitively to the magnetic field signal. By optimizing the distance between the trigger piece 335 and the Hall sensor, the stable triggering of the Hall sensor is further ensured, and the mode switching failure caused by insufficient signal strength is avoided.

[0075] At the same time, the limiting hole 331b provides a fixing structure for the trigger piece 335, which not only limits the movement of the trigger piece 335, but also prevents the trigger piece 335 from shifting or loosening due to vibration or external force during use. Such fixing effect enhances the reliability of the trigger piece 335, ensures that the charging interface 33 can maintain functional stability in long-term use, thereby prolonging the service life of the device and improving user experience.

[0076] Of course, the design of the present application is not limited to this. In other embodiments, the trigger piece 335 can also be fixed to the inner surface or outer surface of the shell 331 by adhesion, bayonet, etc., or installed in the accommodating cavity 331c.

[0077] In some embodiments, the limiting hole 331b forms a first opening on the outer surface of the panel 331a, and one end of the trigger piece 335 is exposed through the first opening. Among them, the magnetic pole end refers to the two end parts of the trigger piece 335, and each end represents one magnetic pole of the trigger piece 335, i.e. north pole (N pole) or south pole (S pole). The trigger piece 335 generates a magnetic field through its magnetic pole end, and the magnetic field direction points from the north pole (N pole) to the south pole (S pole).

[0078] Through this structure, the exposed magnetic pole end can reduce the shielding and attenuation effect of the shell 331 material on the magnetic field, so that the magnetic field generated by the trigger piece 335 is more concentrated and has higher strength, thereby ensuring that the Hall sensor in the control box 2 can reliably detect the magnetic field signal. The Hall sensor can accurately determine whether the charging interface 33 is correctly connected according to the presence or absence of the trigger piece 335 signal, thereby realizing stable switching between the charging mode and the power supply mode.

[0079] In some embodiments, the other end of the trigger piece 335 is mounted on the circuit board 336. With this design, the additional fixing structure of the trigger piece 335 is omitted, and the support and positioning functions of the trigger piece 335 are provided by the circuit board 336, thereby simplifying the overall structural design of the charging interface 33, reducing the number of components, and reducing the production cost and assembly difficulty. In addition, in cooperation with the design of the limiting hole 331b, the trigger piece 335 can realize accurate installation position through the geometric limitation of the limiting hole 331b, and at the same time prevent the trigger piece 335 from shifting or loosening during use. The limiting hole 331b cooperates with the circuit board 336 to provide multiple fixation for the trigger piece 335, further enhancing the stability and durability of the installation of the trigger piece 335.

[0080] Of course, the design of the present application is not limited thereto, and in other embodiments, the trigger piece 335 can also be mounted on the shell 331 without relying on the circuit board 336.

[0081] In some embodiments, the charging interface 33 further comprises two second terminals 337 provided on the shell 331, both of which are electrically connected with the circuit board 336, and both of which are exposed from the outer surface of the surrounding plate 331e and used for magnetic attraction connection with the charging electrode 11 of the patch 1 and conduction.

[0082] Specifically, the side of the surrounding plate 331e opposite to the panel 331a is provided with two through holes 331f, one end of the two second terminals 337 is mounted on the circuit board 336 and electrically connected with the circuit board 336, and the other end of the two second terminals 337 is respectively inserted into the two through holes 331f.

[0083] With this design, the second terminal 337 can provide continuous power supply for the patch 1 through the connection with the charging electrode 11. In this way, the charging line 3 can not only charge the control box 2, but also maintain the working state of the patch 1 during charging, thereby ensuring the continuity and efficiency of the patch 1 during treatment. This dual power supply mode effectively solves the problem that the patch 1 cannot be powered in the charging state of the control box 2 in the traditional scheme, so that the user does not need to worry about the problem of treatment suspension when the control box 2 is charging, thereby ensuring the uninterrupted light therapy effect.

[0084] Alternatively, at least one of the two second terminals 337 has an end portion not higher than the outer surface of the surrounding plate 331e. With this design, the end portion of the second terminal 337 is covered or surrounded by the outer surface of the surrounding plate 331e, thereby avoiding direct exposure of the end portion to the external environment. In this way, the opportunity of contact between external conductors (such as metal objects) and the second terminal 337 and the formation of short circuit is greatly reduced. This can effectively prevent short circuit phenomenon caused by accidental touch or contact with external objects, thereby improving the safety of the equipment.

[0085] In some embodiments, the second terminals 337 are made of passive magnetic material. Since passive magnetic material does not actively generate magnetic field, the use of passive magnetic material for the two second terminals 337 can ensure the magnetic attraction reliability between the second terminals 337 and the charging electrodes 11 of the patch 1 (usually made of permanent magnetic material), while effectively reducing the magnetic interference that the second terminals 337 may

[0086] In some embodiments, the second terminals 337 are made of permanent magnetic material, such as neodymium iron boron (NdFeB), ferrite, samarium cobalt (SmCo), etc. These materials can generate a sustained magnetic field, which are suitable for use as active magnetic components in magnetic attraction connection. In this way, on the one hand, the stability of the connection between the charging interface 33 and the patch 1 can be further enhanced, and on the other hand, the alignment and attraction of the second terminals 337 and the charging electrodes 11 can be facilitated.

[0087] In some embodiments, the housing 331 is provided with a positioning slot 333, which is shaped to match the control box 2 (i.e., the shape of the positioning slot 333 is designed according to the contour features of the control box 2) for inserting the control box 2, and the two first terminals 332a are located in the positioning slot 333.

[0088] Specifically, the panel 331a constitutes the bottom wall of the positioning slot 333, so that the two first terminals 332a are exposed from the bottom wall of the positioning slot 333. It should be noted that the design of the present application is not limited thereto, and in other embodiments, the second terminals 337 can also be exposed from the side wall of the positioning slot 333. Specifically, the positioning slot 333 can be a groove structure with a specific geometric shape, which is shaped and sized to match the contour shape of the control box 2. When the user approaches the charging interface 33 to the control box 2, the control box 2 can be inserted into the positioning slot 333. Since the shape of the positioning slot 333 matches the control box 2, it can be ensured that the two first terminals 332a on the charging interface 33 can be precisely connected with the two magnetic attraction electrodes 21 on the control box 2, thereby ensuring the reliability of the charging.

[0089] By providing the positioning slot 333, on the one hand, the user can conveniently connect the charging interface 33 and the control box 2, and on the other hand, the connection problem caused by the positional deviation between the first terminals 332a and the magnetic attraction electrodes 21 can be avoided. In addition, since the positioning slot 333 can be directly formed integrally by the housing 331, without the need for additional parts or assembly processes, the production process of the charging interface 33 can be simplified, and the manufacturing cost thereof can be reduced.

[0090] In some embodiments, the sidewall of the positioning groove 333 is provided with a fool-proof groove 334 extending along the depth direction of the positioning groove 333, which is designed in shape and size to match the protruding structure 22 on the sidewall of the control box 2 for the matching insertion of the protruding structure 22 on the control box 2.

[0091] Specifically, when the user inserts the control box 2 into the positioning groove 333, the fool-proof groove 334 can accommodate the protruding structure 22 on the sidewall of the control box 2, so that the control box 2 can only be inserted into the positioning groove 333 in a unique direction. If the user tries to insert the control box 2 in the reverse or wrong direction, the insertion action will be physically blocked due to the misalignment of the protruding structure 22 and the fool-proof groove 334, thereby avoiding the positive and negative reverse connection of the two first terminals 332a and the two magnetic suction electrodes 21. Thus, a safe and reliable charging connection is achieved, improving the safety of charging and the user experience.

[0092] In addition, the fool-proof groove 334 as a groove structure is relatively simple to design and process, and can be obtained by one-piece molding of the shell 331, reducing the production process and complexity and reducing the manufacturing cost. Moreover, the fool-proof groove 334 as a recessed structure is not easy to be worn during use, and is located at the sidewall, which can reduce the direct impact of external force, thereby better resisting daily wear and tear, prolonging the service life and improving the durability of the charging interface 33.

[0093] The above description is only preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
