[0001] The present invention relates to the technical field of electronic product data connection, in particular to a data cable. Background Art

[0002] In daily life, the use of electronic devices such as mobile phones and tablets is becoming more and more widespread, and the frequency of people using these electronic devices is gradually increasing. In order to charge electronic devices in time to ensure the normal use of the devices, people usually carry data cables with them when they go out.

[0003] To accommodate outdoor data cable use, existing cables now feature integrated mosquito repellent devices, such as mosquito coils, to repel mosquitoes while users are using the cables outdoors. However, these cables often draw power from a fixed end of the cable, requiring users to distinguish between the input and output ends. If a power-supply device is connected to the output end, the mosquito coil function will not function properly, compromising the cable's usability. Summary of the Invention

[0010] Preferably, when at least two of the plugs are connected to external devices, the plugs other than the power supply end are defined as external device ends; the power supply end charges and / or transmits data to the external device end through the first control module and the line.

[0011] Preferably, the heating device further comprises a heating structure electrically connected to the PCB board, the PCB board is provided with a protection module corresponding to each of the plugs, and each of the protection modules is electrically connected to the cable, the heating structure and the first control module respectively; The first control module is provided with a preset threshold value, which is a power value of the external device determined based on the state of the external device when the power supply is stable; when the heating device draws power from the power taking end, the first control module detects the output power of the external device connected to the power taking end, and when the output power of the external device is greater than the preset threshold value, the wire body and the heating structure are connected; when the output power of the external device is less than the preset threshold value, the protection module cuts off the electrical connection between the wire body and the heating structure.

[0012] Preferably, a second control module is provided on the PCB board, the second control module is electrically connected to the wire body and the heating structure respectively, and the second control module controls the start state, the shut down state and the working power of the heating structure in the start state; The PCB board is further provided with a step-down module, the input end of the step-down module is electrically connected to the line body, and the output end of the step-down module is electrically connected to the second control module; The step-down module is electrically connected to the heating structure through the second control module; the voltage input to the heating device by the wire is stepped down by the step-down module and then input to the heating structure.

[0013] Preferably, the heating device is arranged at the other end of the wire body away from the plug, and the heating device is provided with a socket; the socket can be pluggably connected to an external data line.

[0014] Preferably, a heat insulation structure is provided on the heating device.

[0015] Compared with the prior art, the data cable of the present invention has the following advantages: 1. The data cable of the present invention includes a heating device; the data cable includes a cable body, on which the heating device is disposed, and the cable body is electrically connected to the heating device; the data cable also includes at least one plug, located at an end of the cable body away from the heating device and electrically connected to the cable body; when the at least one plug is connected to an external device, the heating device draws power from the external device connected to one of the plugs. By designing that the heating device can selectively draw power from any plug, the possibility of a powered device being unable to draw power when connected to any plug is avoided, allowing users to freely connect devices without affecting the normal function of the heating device, thereby improving the usability of the data cable.

[0016] 2. The heating device of the present invention includes a housing and a PCB disposed within the interior space formed by the housing. The PCB is provided with a first control module. When at least one plug is connected to an external device, the first control module detects the type of external device connected to the plug. If the external device is a power-supply device, the plug currently connected to the power-supply device is defined as the power supply terminal, and the heating device draws power from the power supply terminal. By providing the first control module, the device type connected to the plug is detected, and then whether power can be supplied to the heating device, and the power supply terminal is defined as the power supply terminal, further improving the stability and safety of the heating device's power supply and significantly enhancing the usability of the data cable.

[0017] 3. While the heating device of the present invention is drawing power, if a plug other than the power supply terminal is connected to a new power-supply device, the first control module defines the plug connected to one end of the new power-supply device as the second power supply terminal, and the heating device is updated to draw power from the second power supply terminal. By updating the plug definition by the first control module, the data cable can change the power supply direction of the heating device without disconnecting the plug from the external device, reducing the need for users to unplug the plug to change the power supply device and greatly improving the convenience of the data cable.

[0018] 4. When at least two plugs of the present invention are connected to an external device, the plug other than the power supply is defined as the external device. The power supply charges and / or transmits data to the external device via the first control module and the cable. By providing the first control module, when the power supply is connected to an electronic device with OTG functionality, the data cable enables charging and data transmission between the power supply device and the external device, eliminating the need for data transmission between devices through a traditional host such as a computer, thereby improving the practicality of the data cable.

[0019] 5. The heating device of the present invention also includes a heating structure electrically connected to the PCB board. The PCB board is provided with a protection module corresponding to each plug. Each protection module is electrically connected to the wire body, the heating structure and the first control module respectively. The first control module is provided with a preset threshold value, which is the power value of the external device determined based on the state of the external device when the power is stably supplied. When the heating device draws power from the power supply end, the first control module detects the output power of the external device connected to the power supply end. When the output power of the external device is greater than the preset threshold value, the wire body and the heating structure are connected. When the output power of the external device is less than the preset threshold value, the protection module cuts off the electrical connection between the wire body and the heating structure. By setting a protection module that can switch the electrical connection between the wire body and the heating structure according to the output power of the power supply device at the power supply end, when the output power of the power supply device is insufficient, the protection module blocks the mosquito killing module from continuing to draw power from the power supply end, thereby ensuring that the power of the power supply device itself does not decrease too quickly, and preventing interruption or error in data transmission and communication between devices, thereby greatly improving the functional stability and practicality of the data line.

[0020] 6. The present invention includes a second control module disposed on a PCB board, the second control module being electrically connected to the cable and the heating structure, and controlling the operating power of the heating structure in the on, off, and on states. The PCB board also includes a voltage-step-down module, the input of which is electrically connected to the cable, and the output of which is electrically connected to the second control module. The voltage-step-down module is electrically connected to the heating structure via the second control module. The voltage input from the cable to the heating device is stepped down by the voltage-step-down module before being input to the heating structure. On the one hand, by disposing the second control module between the cable and the heating structure, the operating power of the heating structure is controlled, thereby adjusting the heating power of the heating structure during operation, facilitating user selection of a more appropriate operating temperature for the heating device in different operating environments, thereby improving the practicality of the heating device. On the other hand, since the plug can be connected to different types of external devices, each of which has a different output voltage, the voltage input from the cable to the heating device is kept within a certain range. The voltage-step-down module stabilizes the output voltage, preventing the output voltage from being affected by fluctuations in the input voltage from the cable, thereby ensuring the normal operation of the heating structure connected to the other end of the voltage-step-down module, thereby significantly improving the practicality of the heating device.

[0021] 7. The heating device of the present invention is located at the end of the cable away from the plug. The heating device is provided with a socket that can be plugged and unplugged into an external data cable. By providing the socket, the external data cable can be selectively plugged into the heating device. When the heating device is not in use, the cable can be detached and used alone, thereby improving the flexibility and versatility of the data cable.

[0022] 8. The heating device of the present invention is provided with a heat-insulating structure, which prevents users from getting burned due to the high temperature of the heating device during operation, thereby enhancing the safety of the heating device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0040] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0041] See also Figure 1-Figure 5 A first embodiment of the present invention provides a data cable 1, comprising a heating device 2; the data cable 1 comprises a cable body 3, on which the heating device 2 is provided, and the cable body 3 is electrically connected to the heating device 2; the data cable 1 further comprises at least one plug 4, which is located at one end of the cable body 3 away from the heating device 2 and is electrically connected to the cable body 3; when the at least one plug 4 is connected to an external device, the heating device 2 draws power from the external device connected to one of the plugs 4.

[0042] More specifically, in this embodiment, the connector of the plug 4 is a Type-C connector.

[0043] It can be understood that the heating device 2 can optionally draw power from an external device connected to one of the plugs 4, preventing the heating device 2 from having no power input when a power-supply device is connected to either end of the plug 4, thereby improving the usability of the data cable 1.

[0044] Furthermore, the heating device 2 is arranged away from the end of the wire 3 , and the wire 3 includes at least two plugs 4 , at least one of which is located at an end of the wire 3 away from the heating device 2 and is electrically connected to the wire 3 .

[0045] Specifically, in this embodiment, a plug 4 is provided at each end of the line body 3; when both plugs 4 are connected to external devices, charging transmission can be performed normally between the two plugs 4, and the data line can normally realize the charging function.

[0046] Furthermore, the heating device 2 includes a shell 21 and a PCB board 23 arranged in the internal space formed by the shell 21, and a first control module 231 is provided on the PCB board 23; when at least one plug 4 is connected to an external device, the first control module 231 detects the type of external device to which the plug 4 has been connected. If the external device is a power-supply device, the plug 4 currently connected to the power-supply device is defined as the power supply end 41, and the heating device 2 draws power from the power supply end 41.

[0047] Specifically, in this embodiment, the long side dimension of the shell 21 is 60 mm, and the short side dimension is 33 mm; the shell 21 is made of PVC fireproof material.

[0048] More specifically, in this embodiment, the first control module 231 is a PD (Power Delivery) protocol control module.

[0049] The PD protocol is an intelligent power supply protocol that allows devices to communicate power through a data interface, that is, to exchange information between the power supply device and the powered device, so that the devices can dynamically negotiate voltage and current through the data interface, thereby achieving efficient and fast charging. Furthermore, the PD protocol control module is a controller that manages power transmission and negotiation through the PD protocol. It has the function of detecting the type of connected device and the PD version it supports. At the same time, it can dynamically adjust the communication voltage and current in real time according to the device requirements to ensure charging efficiency.

[0050] It can be understood that when the plug 4 is connected to an external device, the external device and the first control module 231 are adaptively matched through the PD protocol. The first control module 231 detects the type of the connected device, determines whether the external device can be used as a power-supply device, and defines the plug 4 connected to one end of the power-supply device as the power-taking end, thereby achieving the effect that the heating device 2 can optionally draw power from either end of the plug 4, which is convenient for users to freely connect devices without affecting the normal use of the functions of the heating device 2, greatly improving the usability of the data cable 1; in addition, the first control module 231 intelligently adapts to the power transmission mode that is most suitable for the external device and the heating device 2 to work at the same time, avoiding damage to the equipment due to voltage or current mismatch between the two, and improving the stability and safety of the power supply of the heating device 2.

[0051] Furthermore, the heating device 2 includes at least one receiving groove 22 provided on the housing 21 ; a mosquito coil is installed in the receiving groove 22 .

[0052] It can be understood that when a mosquito coil is installed in the receiving groove 22 , the heating structure 24 heats the mosquito coil and releases the mosquito repellent inside, thereby realizing the mosquito repellent function of the data cable 1 .

[0053] Furthermore, please combine Figure 4 During the period when the heating device 2 is drawing power, if the plug 4 other than the power supply end 41 is connected to a new power-supply device, the first control module 231 defines the plug 4 connected to one end of the new power-supply device as the second power supply end 43, and the heating device 2 is updated to draw power from the second power supply end 43.

[0054] Specifically, the first control module 231 supports a power role switching function that allows the device to switch between power supply and power receiving roles by coordinating ports of multiple devices through the first control module 231 without disconnecting physical connections.

[0055] It can be understood that during the normal operation of the heating device 2, if the plug 4 other than the power supply end 41 is connected to a new power-supply device, the new power-supply device initiates a power role exchange request to the original power-supply device, and the first control module 231 stops the power supply status of the original power-supply device and redefines the plug currently connected to one end of the new power-supply device as the second power supply end. The heating device 2 is updated from drawing power from the power supply end 41 to drawing power from the second power supply end 43, and there is no need to reconnect the plug 4 to the external device, which facilitates the user to switch the power-supply device without unplugging the plug 4, greatly improving the convenience of using the data cable 1.

[0056] Furthermore, when at least two plugs 4 are connected to external devices, the plugs other than the power supply end 41 are defined as the external device end 42 ; the power supply end 41 charges and / or transmits data to the external device end 42 through the first control module 231 and the line body 3 .

[0057] Specifically, in this embodiment, the power terminal 41 can be used as a port supporting the OTG function.

[0058] More specifically, in this embodiment, the charging direction between the two end devices is that the power-taking end 41 device charges the peripheral end 42 device, that is, the power-taking direction of the peripheral end 42 device is consistent with that of the heating device 2 .

[0059] OTG, or On-The-Go, is a technology that allows data to be transferred between devices. Ports with OTG functionality allow mobile devices (such as mobile phones and tablets) to connect to other USB devices (such as USB flash drives, keyboards, and mice), enabling data transfer and device control between multiple devices without the need for a computer.

[0060] It can be understood that by setting up the first control module, when the power supply end 41 is connected to an electronic device with OTG function, the data cable 1 can realize charging communication and data transmission communication between the device connected to the power supply end 41 and the device connected to the peripheral end 42, which is beneficial to eliminate the step of transmitting data between devices through traditional hosts such as computers, enhances the convenience of data transmission between the two devices, and greatly improves the practicality of the data cable 1.

[0061] More specifically, when the device connected to the power supply terminal 41 and the device connected to the peripheral terminal 42 both support the fast charging function, the first control module 231 identifies and manages the charging protocol of each device, thereby enabling fast charging communication between the devices, and the device connected to the power supply terminal 41 quickly charges the device connected to the peripheral terminal 42.

[0062] Please continue reading Figure 1 、 Figure 3-Figure 6Furthermore, the heating device 2 also includes a heating structure 24 electrically connected to the PCB board 23. The PCB board 23 is provided with a protection module 234 corresponding to each plug 4. Each protection module 234 is electrically connected to the line body 3, the heating structure 24 and the first control module 231 respectively; the first control module 231 is provided with a preset threshold, which is a power value of the external device determined based on the state of stable power supply of the external device; when the heating device 2 draws power from the power taking end 41, the first control module 231 detects the output power of the external device connected to the power taking end 41. When the output power of the external device is greater than the preset threshold, the line body 3 and the heating structure 24 are connected; when the output power of the external device is less than the preset threshold, the protection module 234 cuts off the electrical connection between the line body 3 and the heating structure 24.

[0063] Specifically, in this embodiment, the maximum power supported by the data line 1 is 100W.

[0064] More specifically, in this embodiment, the protection module 234 uses a field effect transistor as a circuit switch.

[0065] A field-effect transistor is a semiconductor device that controls the current path between its source and drain based on the electric field effect, thereby realizing the switching or amplification function of the circuit.

[0066] It can be understood that the heating device 2 needs to allocate power from the wire body 3 to operate normally, and since the heating structure 24 generates heat during the operation of the heating device 2, the power required to be allocated by the heating device 2 is relatively large, which may result in a lower power distribution between the plug 4 and the wire body 3, thereby affecting the function of the data cable 1; in order to ensure the stability of the operating power of the heating device 2 and the normal charging or data transmission function between the power taking end 41 and the external device end 42, and to avoid the rapid reduction of the power of the device connected to the power taking end 41, thereby affecting the battery life of the device, the first control module 231 sets a preset threshold for determining whether the output power of the external device supports the normal operation of the device and the data cable; when the first control module 231 detects that the output power of the external device at the power taking end 41 is less than the preset threshold, the first control module 231 determines that the output power of the external device is insufficient, and controls the protection module 234 to cut off the electrical connection between the wire body 3 and the heating structure 24, preventing the heating device 2 from continuing to draw power from the external device, thereby ensuring the functional stability of the data cable 1 and protecting the battery life of the external device at the power taking end 41.

[0067] Please continue reading Figure 1 、 Figure 3-Figure 8Furthermore, a second control module 235 is provided on the PCB board 23, and the second control module 235 is electrically connected to the wire body 3 and the heating structure 24 respectively, and the second control module 235 controls the start state, the shutdown state and the working power of the heating structure 24 in the start state; a step-down module 233 is also provided on the PCB board 23, and the input end of the step-down module 233 is electrically connected to the wire body 3, and the output end of the step-down module 233 is electrically connected to the second control module 235; the step-down module 233 is electrically connected to the heating structure 24 through the second control module 235; the voltage of the wire body 3 input to the heating device 2 is stepped down by the step-down module 233 and input to the heating structure 24.

[0068] Specifically, in this embodiment, the second control module 235 includes a single-chip microcomputer and a field effect transistor, and a PWM (Pulse-Width Modulation) output pin of the single-chip microcomputer is connected to the gate of the field effect transistor.

[0069] It can be understood that when the heating structure 24 needs to adjust the operating frequency, the second control module 235 controls the conduction time between the source and drain of the field effect tube by changing the duty cycle of the PWM signal output by the single-chip microcomputer, thereby adjusting the operating power of the heating structure 24, making it easier for the heating device 2 to switch to an operating temperature that is more suitable for the volatilization of mosquito coils in different usage environments, thereby improving the mosquito repellent effect of the heating device 2.

[0070] Specifically, since the battery and internal circuits of the electronic device all operate based on direct current, the external device outputs direct current to the data line 1 during charging or data transmission. In this embodiment, the step-down module 233 is a DC-DC step-down module.

[0071] It can be understood that since the voltage inside the wire body 3 is affected by different external devices connected to the plug 4, the input voltage of the wire body 3 to the heating device 2 has a certain volatility; the step-down module 233 steps down the input voltage and outputs it after stabilizing it at a fixed voltage value, thereby ensuring that the heating structure 24 electrically connected to the step-down module 233 can operate at a relatively stable voltage, thereby improving the functional stability of the heating structure 24 and greatly improving the practicality of the heating device 2.

[0072] Specifically, in this embodiment, the acceptable input voltage range of the step-down module 233 is 4V to 28V, and the output voltage of the step-down module 233 is 5V.

[0073] Furthermore, the second control module 235 is also provided with a clock module, so that the second control module 235 can control the timing start and stop of the heating device 2.

[0074] Furthermore, the second control module 235 includes at least one switch button 236 , and the housing 21 is provided with a switch pressing member 211 corresponding to the switch button 236 ; when the switch pressing member 211 is pressed, the switch pressing member 211 moves toward the PCB board 23 and presses the switch button 236 .

[0075] Specifically, in this embodiment, the heating device 2 is provided with a switch button 236 and a corresponding switch pressing member 211 .

[0076] It can be understood that the setting of the switch button 236 makes it convenient for the user to actively control the working status of the heating device 2, and the user can control the heating device 2 by pressing the switch pressing part 211 to abut the switch button 236, which is convenient for the user's switch operation and helps the user to intuitively obtain operation feedback, thereby enhancing the operating convenience and ease of use of the heating device 2.

[0077] See also Figures 1-10 Furthermore, the heating device 2 includes at least one accommodating groove 22 opened on the shell 21, and the accommodating groove 22 is opened corresponding to the heating structure 24; the PCB board 23 is provided with a slot 232 corresponding to the accommodating groove 22, and the heating structure 24 is located in the slot 232.

[0078] Specifically, in this embodiment, the heating device 2 is provided with two receiving grooves 22 , and the two receiving grooves are respectively provided on two sides of the PCB board 23 .

[0079] It can be understood that when a mosquito coil is installed in the receiving groove 22 , the heating structure 24 heats the mosquito coil and releases the mosquito repellent inside, thereby realizing the mosquito repellent function of the data cable 1 .

[0080] More specifically, the height of the receiving groove 22 disposed on one side of the PCB board 23 is smaller than the height of the receiving groove 22 disposed on the other side of the PCB board 23 .

[0081] It is understandable that since there are many types of mosquito coils that users can put in, and the mosquito coils have different thicknesses due to different types, the different height settings of the receiving grooves 22 on both sides are conducive to users installing mosquito coils of different thicknesses, preventing the mosquito coils from being unable to be inserted into the receiving grooves 22 or easily slipping out of the receiving grooves 22, thereby effectively improving the practicality of the heating device 2.

[0082] As an optional embodiment, an adjusting device capable of adjusting the height of the accommodating groove 22 is provided inside the accommodating groove 22 .

[0083] Specifically, in this embodiment, the heating structure 24 is configured as a ceramic heating element, and the shape of the ceramic heating element is circular.

[0084] It can be understood that when the PCB board 23 does not have the slot 232, the heating structure 24 and the PCB board 23 are in a stacked position relationship, and the total thickness of the two is the sum of their respective thicknesses; after the slot 232 is opened, the heating structure 24 is embedded in the slot 232 of the PCB board 23, and the total thickness of the two is the maximum thickness of the PCB board 23 or the heating structure 24, which greatly reduces the space required for the two to occupy inside the shell 21, is conducive to making a smaller heating device 2, avoiding the heating device 2 affecting the user experience when using the data cable 1, and enhancing the portability and ease of use of the data cable 1.

[0085] More specifically, in this embodiment, the slot 232 is in the shape of a rectangular hole, and the short side of the slot 232 is longer than the diameter of the heating structure 24, that is, there is a certain space between the slot 232 and the heating structure 24, which is beneficial to the heat dissipation of the heating structure 24, and prevents the heat emitted by the heating structure 24 from affecting the working performance of the PCB board 23 and the circuit modules and electronic components thereon, thereby ensuring the functional stability of the heating device 2.

[0086] Furthermore, the shell 21 is provided with two opposite receiving grooves 22 arranged on both sides of the PCB board 23, and a pad 26 is provided in the receiving groove 22. The pad 26 covers the slot hole 232. One side of the pad 26 is exposed in the receiving groove 22, and the other side contacts the heating structure 24.

[0087] It can be understood that when the mosquito coil is installed in the accommodating groove 22, the pad 26 isolates the PCB board 23 and the heating structure 24 from the mosquito coil, thereby preventing the mosquito coil from directly contacting the PCB board 23 or the heating structure 24, causing the PCB board 23 to be scratched or damaged or affecting the electrical connection between the heating structure 24 and the PCB board 23, thereby improving the functional stability and service life of the internal structure of the heating device 2.

[0088] It can be understood that the two closed pads 26 are also helpful in preventing dust from falling into the PCB board 23, thereby preventing the dust from corroding the components and metal pins on the PCB board 23 and affecting the normal operation of the PCB board 23, thereby improving the functional stability and service life of the PCB board 23.

[0089] Specifically, in this embodiment, the pad 26 is made of a heat-conductive hard material, thereby ensuring that the pad 26 does not affect the heating effect of the heating structure 24 on the mosquito coil; the pad 26 and the PCB board 23 are bonded with heat-insulating glue.

[0090] It can be understood that the design of having two back-to-back receiving grooves 22 on both sides of the heating structure 24 is conducive to the heating structure 24 heating the mosquito coils in the two receiving grooves 22 at the same time, greatly improving the utilization rate of the heating structure 24; in addition, the design of the double receiving grooves 22 makes it convenient for users to optionally place two mosquito coils for use at the same time, and the mosquito repellent effect and mosquito repellent range that can be achieved by the heating device 2 per unit time are greatly improved, which is suitable for use in large spaces indoors or outdoors, and greatly increases the practicality of the heating device 2.

[0091] Specifically, in this embodiment, the two pads 26 and the heating structure 24 are bonded together by thermally conductive adhesive, which further enhances the stability of the heating structure 24 in the space formed by the two pads 26 and prevents the heating structure 24 from being scratched or broken due to relative movement with the pads 26, thereby preventing damage to the heating structure 24.

[0092] More specifically, in this embodiment, the pad 26 extends near both ends of the side of the PCB board 23 and forms a protective wall that partially surrounds the side of the PCB board 23, further protecting the structure of the PCB board 23 and preventing it from being bumped.

[0093] Furthermore, a first baffle 212 and a second baffle 213 are provided on the inner wall of the shell 21, and the first baffle 212 and the second baffle 213 define the mosquito coil installation position; the pad 26 abuts against the first baffle 212 on one side close to the first baffle 212, and abuts against the second baffle 213 on the other side close to the second baffle 213, and the PCB board 23 and the heating structure 24 are sealed in the sealed cavity formed by the first baffle 212, the second baffle 213 and the pad 26.

[0094] It can be understood that by setting up a sealed cavity formed by the first baffle 212, the second baffle 213 and the pad 26, the PCB board 23 and the heating structure 24 are located in the internal space and are protected by the pad 26 and the shell 21, effectively avoiding the damage to the PCB board 23 or the heating structure 24 caused by external environmental factors such as splashing water or collision, thereby improving the functional stability of the PCB board 23 and the heating structure 24, and greatly enhancing the practicality and service life of the heating device 2.

[0095] More specifically, the first baffle 212 and the second baffle 213 separate the pad 26 from the circuit modules and electronic components on the PCB board 23, effectively preventing heat from the pad 26 from being transferred to the circuit modules and electronic components, thereby preventing the above-mentioned two from being affected in function or even damaged in structure due to higher temperatures, thereby greatly improving the functional stability and service life of the PCB board 23.

[0096] Furthermore, the heating device 2 is provided with at least one indicator light 25 , and the indicator light 25 is electrically connected to the PCB board 23 .

[0097] Specifically, in this embodiment, the heating device 2 is provided with three indicator lights 25 , and the three indicator lights 25 are all LED lights.

[0098] More specifically, in this embodiment, the indicator light 25 is disposed on a side of the PCB board 23 where the switch button 236 is disposed, and the housing 21 is provided with a through hole corresponding to the indicator light 25 to achieve light transmission.

[0099] It can be understood that the setting of the indicator light 25 is conducive to the user to intuitively judge the working condition of the heating device 2 through the status of the indicator light 25, realizing the visualization of the working status of the heating device 2, thereby facilitating the user to adjust the usage mode of the data cable 1 or switch the current status of the heating device 2 according to the current working status of the heating device 2, thereby improving the usability of the data cable 1.

[0100] It can be understood that the setting of the indicator light 25 also serves to remind the user whether the heating device 2 is working, thereby preventing the user from making misoperations during the heating period of the heating device 2, which may cause burns, and improving the safety of the data cable 1.

[0101] More specifically, the second control module 235 can actively control the lighting state, lighting duration and brightness of the indicator light 25, so that the indicator light 25 can be used as a night light or a breathing light, enhancing the practicality and aesthetics of the data cable 1.

[0102] Furthermore, the voltage reduction module 233 is disposed at one end of the PCB board 23 away from the first control module 231 , and the heating structure 24 is electrically connected to the end of the PCB board 23 where the voltage reduction module 233 is disposed.

[0103] It can be understood that when the first control module 231 is set close to the working circuits such as the step-down module 233 or the heating structure 24, the step-down module 233 may be affected by the signal of the first control module 231 and caused to be falsely triggered. The first control module 231 may also be affected by the interference of the working signal of the step-down module 233 or the heating structure 24. The design of separating the above modules effectively avoids the possible false triggering of the step-down module 233, prevents the heating device 2 from accidentally starting in the non-working state, and greatly enhances the safety of the use of the heating device 2.

[0104] More specifically, in this embodiment, the switch button 236 is disposed at one end of the PCB board 23 close to the first control module 231 , and the indicator light 25 is disposed at one end of the PCB board 23 away from the first control module 231 .

[0105] Furthermore, as an optional embodiment, the heating device 2 is arranged at the other end of the wire body 3 away from the plug 4, and the heating device 2 is provided with a socket; the socket can be pluggably connected to an external data cable.

[0106] Specifically, in this embodiment, the socket is one of a Type-C interface, a USB interface or a lighting interface.

[0107] It can be understood that by providing a socket, the external data cable can be optionally connected to the heating device 2. When the heating device 2 is not in use, the external data cable can be removed and used separately, thereby improving the flexibility and versatility of the data cable 1.

[0108] See also Figure 11 A second embodiment of the present invention provides a data cable 100 , wherein a heat insulating structure 5 is provided on the heating device 2 .

[0109] Specifically, in this embodiment, the heat insulating structure 5 is a silicone heat insulating sleeve, and the silicone heat insulating sleeve is open at one end corresponding to the heating device 2 , and a through hole is opened at the other end corresponding to the heating device 2 corresponding to the wire body 3 .

[0110] It can be understood that the provision of the heat insulation structure 5 prevents the user from being scalded due to the high temperature of the heating device 2 during use, thereby enhancing the safety of the heating device 2.

[0111] Compared with the prior art, the data cable of the present invention has the following advantages: 1. The data cable of the present invention includes a heating device; the data cable includes a cable body, on which the heating device is disposed, and the cable body is electrically connected to the heating device; the data cable also includes at least one plug, located at an end of the cable body away from the heating device and electrically connected to the cable body; when the at least one plug is connected to an external device, the heating device draws power from the external device connected to one of the plugs. By designing that the heating device can selectively draw power from any plug, the possibility of a powered device being unable to draw power when connected to any plug is avoided, allowing users to freely connect devices without affecting the normal function of the heating device, thereby improving the usability of the data cable.

[0112] 2. The heating device of the present invention includes a housing and a PCB disposed within the interior space formed by the housing. The PCB is provided with a first control module. When at least one plug is connected to an external device, the first control module detects the type of external device connected to the plug. If the external device is a power-supply device, the plug currently connected to the power-supply device is defined as the power supply terminal, and the heating device draws power from the power supply terminal. By providing the first control module, the device type connected to the plug is detected, and then whether power can be supplied to the heating device, and the power supply terminal is defined as the power supply terminal, further improving the stability and safety of the heating device's power supply and significantly enhancing the usability of the data cable.

[0113] 3. While the heating device of the present invention is drawing power, if a plug other than the power supply terminal is connected to a new power-supply device, the first control module defines the plug connected to one end of the new power-supply device as the second power supply terminal, and the heating device is updated to draw power from the second power supply terminal. By updating the plug definition by the first control module, the data cable can change the power supply direction of the heating device without disconnecting the plug from the external device, reducing the need for users to unplug the plug to change the power supply device and greatly improving the convenience of the data cable.

[0114] 4. When at least two plugs of the present invention are connected to an external device, the plug other than the power supply is defined as the external device. The power supply charges and / or transmits data to the external device via the first control module and the cable. By providing the first control module, when the power supply is connected to an electronic device with OTG functionality, the data cable enables charging and data transmission between the power supply device and the external device, eliminating the need for data transmission between devices through a traditional host such as a computer, thereby improving the practicality of the data cable.

[0115] 5. The heating device of the present invention also includes a heating structure electrically connected to the PCB board. The PCB board is provided with a protection module corresponding to each plug. Each protection module is electrically connected to the wire body, the heating structure and the first control module respectively. The first control module is provided with a preset threshold value, which is the power value of the external device determined based on the state of the external device when the power is stably supplied. When the heating device draws power from the power supply end, the first control module detects the output power of the external device connected to the power supply end. When the output power of the external device is greater than the preset threshold value, the wire body and the heating structure are connected. When the output power of the external device is less than the preset threshold value, the protection module cuts off the electrical connection between the wire body and the heating structure. By setting a protection module that can switch the electrical connection between the wire body and the heating structure according to the output power of the power supply device at the power supply end, when the output power of the power supply device is insufficient, the protection module blocks the mosquito killing module from continuing to draw power from the power supply end, thereby ensuring that the power of the power supply device itself does not decrease too quickly, and preventing interruption or error in data transmission and communication between devices, thereby greatly improving the functional stability and practicality of the data line.

[0116] 6. The present invention includes a second control module disposed on a PCB board, the second control module being electrically connected to the cable and the heating structure, and controlling the operating power of the heating structure in the on, off, and on states. The PCB board also includes a voltage-step-down module, the input of which is electrically connected to the cable, and the output of which is electrically connected to the second control module. The voltage-step-down module is electrically connected to the heating structure via the second control module. The voltage input from the cable to the heating device is stepped down by the voltage-step-down module before being input to the heating structure. On the one hand, by disposing the second control module between the cable and the heating structure, the operating power of the heating structure is controlled, thereby adjusting the heating power of the heating structure during operation, facilitating user selection of a more appropriate operating temperature for the heating device in different operating environments, thereby improving the practicality of the heating device. On the other hand, since the plug can be connected to different types of external devices, each of which has a different output voltage, the voltage input from the cable to the heating device is kept within a certain range. The voltage-step-down module stabilizes the output voltage, preventing the output voltage from being affected by fluctuations in the input voltage from the cable, thereby ensuring the normal operation of the heating structure connected to the other end of the voltage-step-down module, thereby significantly improving the practicality of the heating device.

[0117] 7. The heating device of the present invention is located at the end of the cable away from the plug. The heating device is provided with a socket that can be plugged and unplugged into an external data cable. By providing the socket, the external data cable can be selectively plugged into the heating device. When the heating device is not in use, the cable can be detached and used alone, thereby improving the flexibility and versatility of the data cable.

[0118] 8. The heating device of the present invention is provided with a heat-insulating structure, which prevents users from getting burned due to the high temperature of the heating device during operation, thereby enhancing the safety of the heating device.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
