[0017] Preferably, a limiting member is provided on the inner wall of the receiving groove on the side away from the PCB board. The limiting member is strip-shaped and protrudes from both ends toward the center toward the PCB board.

[0018] Preferably, a heat insulation structure is fitted onto the housing.

[0019] Compared with the prior art, the data cable of this utility model has the following advantages:

[0020] 1. The data cable of this utility model includes a heating device, which comprises a housing, at least one receiving slot formed on the housing, a PCB board disposed in the internal space formed by the housing, and a heating structure electrically connected to the PCB board; the PCB board has a slot corresponding to the receiving slot, and the heating structure is embedded in the slot; 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 two plugs, wherein at least one plug is located at one end of the cable body and electrically connected to the cable body, and at least one plug is located at the other end of the cable body and electrically connected to the cable body. By designing a slot in the PCB board, the heating structure is embedded in the slot, which greatly reduces the total volume occupied by the heating structure and the PCB board in the internal space of the housing, which is conducive to making a smaller heating device and improving the portability of the data cable.

[0021] 2. The receiving groove of this utility model is provided with a pad, which covers the groove hole. One side of the pad is exposed in the receiving groove, and the other side contacts the heating structure. By setting the pad to separate the PCB board and the mosquito coil, the pad provides support when the mosquito coil is placed in the receiving groove, and at the same time protects the PCB board and the heating structure embedded in the groove hole. This prevents direct contact and relative movement between the PCB board and the mosquito coil during insertion, removal, or use, which could lead to scratches or damage to the PCB board or the heating structure. This improves the functional stability and service life of the PCB board and the heating structure.

[0022] 3. In this invention, the edge of the PCB board near the opening of the receiving groove is the first side, and the edge of the housing near the first side is the second side. The two ends of the pad near the first side are bent along a plane parallel to the first side to form a protective wall, which is sandwiched between the first and second sides. Through this protective wall design, direct contact between the first and second sides is blocked, preventing direct friction or collision that could damage the PCB board and affect its normal function. This significantly improves the functional stability and service life of the PCB board.

[0023] 4. The housing of this utility model has two receiving slots, which are respectively located on both sides of the PCB board; the heating structure is sandwiched between two pads; the height of the receiving slot located on one side of the PCB board is less than the height of the receiving slot located on the other side of the PCB board. By opening two opposite receiving slots on both sides of the heating structure, the heating structure can simultaneously heat the mosquito coils inserted in the two receiving slots, greatly improving the utilization rate of the heating structure; and the mosquito repelling effect and range that the heating device can achieve per unit time are greatly improved, making it suitable for use in large indoor or outdoor spaces.

[0024] 5. The inner wall of the housing of this utility model is provided with a first baffle and a second baffle, which define a mounting position and a first cavity and a second cavity located on both sides of the mounting position; the PCB board includes a first component area and a second component area located on both sides of the slot; the first component area is sealed in the first cavity, and the second component area is sealed in the second cavity. By setting the first component area and the second component area, which can be sealed in the first cavity and the second cavity respectively, the housing seals and protects the important circuit modules and structures on the PCB board, avoids external environmental factors from affecting the normal operation of the PCB board, and improves the functional stability and service life of the PCB board.

[0025] 6. The PCB board of this utility model integrates a first control module and a step-down module. The first control module is located in the first component area, and the connection points of the step-down module and the heating structure to the PCB board are located in the second component area. By isolating and sealing the working circuits of the first control module and the step-down module or heating structure, the signal crosstalk that may occur between the first control module and the working circuit is effectively avoided, greatly improving the functional stability of each module.

[0026] 7. In this invention, the pad abuts against the first baffle on one side and against the second baffle on the other side. The PCB board and heating structure are sealed within a sealed cavity formed by the first baffle, the second baffle, and the pad. By setting the edge of the pad to abut against the first and second baffles, the two baffles and the pad form a sealed cavity, jointly protecting the PCB board and heating structure within the sealed cavity. This prevents damage to the PCB board or heating structure from external environmental factors such as splashing water or collisions, thus avoiding malfunctions and significantly enhancing the stability and service life of the heating device.

[0027] 8. A limiting member is provided on the inner wall of the receiving groove on the side away from the PCB board. The limiting member is strip-shaped and protrudes from both ends towards the center towards the PCB board. When the mosquito coil is inserted into the receiving groove, the limiting member abuts against the mosquito coil. Through the abutting relationship between the limiting member and the mosquito coil, the mosquito coil is prevented from accidentally falling off due to external forces such as shaking during the operation of the heating device, thus affecting the mosquito repellent effect of the heating device.

[0028] 9. A heat insulation structure is fitted onto the shell of this utility model. This heat insulation structure prevents users from being burned by the high temperature of the heating device during operation, thus enhancing the safety of the heating device. Attached Figure Description

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0050] Please see Figure 1 , Figures 4-6 The first embodiment of this utility model provides a data cable 1, including a heating device 2. The heating device 2 includes a housing 21, at least one receiving groove 22 formed on the housing 21, a PCB board 25 disposed in the internal space formed by the housing 21, and a heating structure 23 electrically connected to the PCB board 25. The PCB board 25 has a slot 255 corresponding to the receiving groove 22, and the heating structure 23 is embedded in the slot 255. The data cable 1 includes a cable body 3, on which the heating device 2 is disposed, and the cable body 3 is electrically connected to the heating device 2. The data cable 1 also includes at least two plugs 4, wherein at least one plug 4 is located at one end of the cable body 3 and electrically connected to the cable body 3, and at least one plug 4 is located at the other end of the cable body 3 and electrically connected to the cable body 3.

[0051] Specifically, in this embodiment, the long side of the shell 21 is 60mm and the short side is 33mm; the shell 21 is made of PVC fireproof material.

[0052] Specifically, in this embodiment, each end of the cable 3 is provided with a plug 4, and the connector of the plug 4 is a Type-C connector.

[0053] Understandably, when the PCB board 25 does not have a slot 255, the heating structure 23 and the PCB board 25 are stacked, and their total thickness is the sum of their individual thicknesses. After the slot 255 is opened, the heating structure 23 is embedded in the slot 255 of the PCB board 25, and the total thickness of the two is the maximum thickness of either the PCB board 25 or the heating structure 23. This greatly reduces the space required for both to occupy inside the housing 21, which is beneficial for making a smaller heating device 2. It also prevents the heating device 2 from affecting the user's experience when using the data cable 1, and enhances the portability and ease of use of the data cable 1.

[0054] Furthermore, mosquito coils are installed inside the receiving trough 22.

[0055] Understandably, when a mosquito coil is installed in the receiving slot 22, the heating structure 23 heats the mosquito coil and causes it to release the mosquito repellent inside, thereby realizing the mosquito repellent function of the data cable 1.

[0056] Please see Figures 1-4 Furthermore, a pad 24 is provided inside the receiving groove 22, which covers the groove hole 255. One side of the pad 24 is exposed inside the receiving groove 22, and the other side is in contact with the heating structure 23.

[0057] Specifically, in this embodiment, the pad 24 is made of a thermally conductive rigid material to ensure that the pad 24 does not affect the heating effect of the heating structure 23 on the mosquito coil; the pad 24 and the PCB board 25 are bonded together with heat-insulating adhesive.

[0058] Understandably, the pad 24 provides support when the mosquito coil is placed in the receiving slot 22, providing a complete placement platform for the mosquito coil, making it easy for users to stably place mosquito coils with a certain thickness and weight.

[0059] Understandably, when the mosquito coil is installed in the receiving slot 22, the pad 24 isolates the PCB board 25 and the heating structure 23 from the mosquito coil, preventing direct contact between the mosquito coil and the PCB board 25 or the heating structure 23. When the mosquito coil is plugged in or replaced, or when it shakes during use, the pad 24 protects the PCB board 25 and the heating structure 23, preventing scratches and damage caused by friction between the mosquito coil and the PCB board 25. At the same time, it reduces the external influence that may affect the electrical connection between the heating structure 23 and the PCB board 25, thereby greatly improving the functional stability and service life of the internal structure of the heating device 2.

[0060] Furthermore, the edge of the PCB board 25 near the opening of the receiving groove 22 is the first side 257, and the edge of the housing 21 near the first side 257 is the second side 212; the two ends of the pad 24 near the first side 257 are bent along a plane direction parallel to the first side 257 to form a protective wall 241, and the protective wall 241 is sandwiched between the first side 257 and the second side 212.

[0061] Understandably, the protective wall 241 surrounds and protects the first side 257, preventing friction and collision between the first side 257 and the second side 212, which could damage the PCB board 25 and affect its normal function, thus improving the functional stability and service life of the PCB board 25.

[0062] Furthermore, the housing 21 has two receiving grooves 22, which are respectively located on both sides of the PCB board 25; the heating structure 23 is sandwiched between the two pads 24; the height of the receiving groove 22 located on one side of the PCB board 25 is less than the height of the receiving groove 22 located on the other side of the PCB board 25.

[0063] Understandably, the design of the dual-slot 22 allows users to optionally place two mosquito coils for simultaneous use, significantly improving the mosquito-repelling effect and range achievable by the heating device 2 per unit time. This makes it suitable for use in large indoor or outdoor spaces, greatly increasing the practicality of the heating device 2.

[0064] Understandably, the two receiving slots 22 set opposite to the PCB board 25 are conducive to the heating structure 23 heating the receiving slots 22 on both sides at the same time, which greatly improves the utilization rate of the heating structure 23. When mosquito coils are placed in both receiving slots 22, the heating device 2 can obtain a better mosquito repelling effect without having to increase the heating power.

[0065] Understandably, since there are various types of mosquito coils that users can put in, and the mosquito coils have different thicknesses depending on the type, the different heights of the two side receiving slots 22 make it easier for users to install mosquito coils of different thicknesses, preventing the mosquito coils from not being able to be inserted into the receiving slots 22 or from easily slipping out of the receiving slots 22, thus effectively improving the practicality of the heating device 2.

[0066] As an optional implementation, an adjustment device is provided inside the receiving groove 22 to adjust the height of the receiving groove 22.

[0067] Specifically, in this embodiment, the two pads 24 are bonded to the heating structure 23 by thermally conductive adhesive, and the pads 24 are also bonded to the PCB board 25 by adhesive.

[0068] Understandably, the design of the heating structure 23 sandwiched between the two pads 24 confines the heating structure 23 within the space formed by the combination of the two pads 24, effectively protecting the heating structure 23 from being scratched by the mosquito coils on both sides; the adhesive bonding and fixing setting further enhances the stability between the PCB board 25, the pads 24 and the heating structure 23, preventing relative movement between the pads 24 and the heating structure 23 or the PCB board 25 when the heating device 2 shakes during use, which could lead to scratches or damage to the heating structure 23 or the PCB board 25, and greatly improves the internal structural stability of the heating device 2.

[0069] Understandably, the closed pads 24 also help to prevent dust from falling into the PCB board 25, thereby avoiding dust from corroding the components and metal pins on the PCB board 25 and affecting the normal operation of the PCB board 25, thus improving the functional stability and service life of the PCB board 25.

[0070] Please see Figures 1-6Furthermore, the inner wall of the housing 21 is provided with a first baffle 213 and a second baffle 214, which define the mounting position and the first cavity 215 and the second cavity 216 located on both sides of the mounting position; the PCB board 25 includes a first component area 258 and a second component area 259 located on both sides of the slot 255; the first component area 258 is sealed in the first cavity 215 and the second component area 259 is sealed in the second cavity 216.

[0071] Specifically, in this embodiment, when the mosquito coil is placed in the receiving slot 22, the first baffle 213 and the second baffle 214 abut against both ends of the mosquito coil.

[0072] Understandably, the first baffle 213 and the second baffle 214 restrict the movement of the mosquito coil towards the line 3, preventing the mosquito coil from sliding excessively in the receiving groove 22, which could cause the mosquito coil to deviate from the optimal heating position of the heating structure 23, thus affecting the mosquito repellent effect of the heating device 2.

[0073] Understandably, since the first component area 258 and the second component area 259 are respectively sealed in the first cavity 215 and the second cavity 216, the circuit modules and electronic components on the PCB board 25 located in the above two areas are all sealed and protected. On the one hand, this avoids the possibility of the mosquito coil sliding and damaging the circuit modules and electronic components on the PCB board 25; on the other hand, the sealed structure helps to prevent dust from falling into the PCB board 25, thereby preventing dust from corroding the electronic components and metal pins on the PCB board 25, further reducing the impact of external environmental factors on the PCB board 25, and greatly improving the functional stability and service life of the PCB board 25.

[0074] Furthermore, the PCB board 25 integrates a first control module 251 and a step-down module 253. The first control module 251 is located in the first component area 258, and the connection points of the step-down module 253 and the heating structure 23 with the PCB board 25 are located in the second component area 259.

[0075] When the first control module 251 is close to the working circuits such as the step-down module 253 or the heating structure 23, the step-down module 253 may be falsely triggered due to the influence of the signal from the first control module 251. Similarly, the first control module 251 may also be affected by the working signal interference from the step-down module 253 or the heating structure 23.

[0076] Understandably, the first cavity 215 and the second cavity 216 separate the first control module 251 from the working circuits such as the step-down module 253 and seal the working environment respectively, which effectively reduces crosstalk between working signals, avoids false triggering that may occur in the step-down module 253, prevents the heating device 2 from being accidentally started in a non-working state, and greatly enhances the safety of the heating device 2.

[0077] Furthermore, the PCB board 25 also integrates a second control module 252 and a protection module 254 corresponding to each plug 4; part of the second control module 252 and the protection module 254 are located in the first component area 258, and the other part is located in the second component area 259.

[0078] Understandably, the second control module 252 controls both the first control module 251 in the first cavity 215 and the working circuits in the second cavity 216. The design of being located on both sides is beneficial for the second control module 252 to respond to and control the circuits on both sides.

[0079] Understandably, each protection module 254 is located in a cavity close to the corresponding plug 4, which effectively shortens the connection distance between the protection module 254 and the corresponding plug 4, and improves the response speed and performance of the protection module 254.

[0080] Furthermore, the side of the pad 24 near the first baffle 213 abuts against the first baffle 213, and the side near the second baffle 214 abuts against the second baffle 214. The PCB board 25 and the heating structure 23 are sealed in the sealed cavity formed by the first baffle 213, the second baffle 214 and the pad 24.

[0081] Understandably, by setting up a sealed cavity formed by the first baffle 213, the second baffle 214 and the pad 24, the PCB board 25 and the heating structure 23 are located in the sealed cavity and are protected by the pad 24, the first baffle 213 and the second baffle 214. This effectively avoids damage to the PCB board 25 or the heating structure 23 caused by external environmental factors such as splashing water or collisions, improves the functional stability of the PCB board 25 and the heating structure 23, and greatly enhances the practicality and service life of the heating device 2.

[0082] More specifically, the first baffle 213 and the second baffle 214 separate the pad 24 from the circuit modules and electronic components on the PCB board 25, effectively preventing heat transfer from the pad 24 to the circuit modules and electronic components, thereby preventing the above two from being affected by high temperature and even damaged in structure, greatly improving the functional stability and service life of the PCB board 25.

[0083] Furthermore, a limiting member 221 is provided on the inner wall of the receiving groove 22 on the side away from the PCB board 25. The limiting member 221 is strip-shaped and protrudes from both ends to the center towards the PCB board 25.

[0084] Understandably, the limiting member 221 engages and fixes the mosquito coil in the receiving groove 22, and effectively prevents it from moving within the receiving groove 22. This prevents the mosquito coil from accidentally coming out of the receiving groove 22 when the heating device 2 shakes, thereby affecting the mosquito repellent effect of the heating device 2 and causing a waste of electricity for the powered equipment.

[0085] Understandably, when the mosquito coil is inserted into the receiving groove 22, it can be inserted from either end of the receiving groove 22. The trapezoidal design with shorter ends of the limiting member 221 is conducive to the insertion of the mosquito coil from either side of the receiving groove 22. When the mosquito coil is fully inserted into the position corresponding to the heating structure 23 in the receiving groove 22, the upper part of the higher trapezoidal body of the limiting member 221 engages with the mosquito coil and positions it in the receiving groove 22. This ensures that the mosquito coil is fixed in a position that can better receive the heat from the heating structure 23, greatly improving the ease of use and mosquito repellency of the heating device 2.

[0086] Please see Figure 7 The second embodiment of this utility model provides a data cable 100, on which a heat insulation structure 5 is sleeved on the shell 21.

[0087] Specifically, in this embodiment, the heat insulation structure 5 is a silicone heat insulation sleeve, and the silicone heat insulation sleeve is open at one end of the heating device 2, and a through hole is opened at the other end of the heating device 2 corresponding to the wire 3.

[0088] Understandably, the heat insulation structure 5 is designed to prevent users from being burned by the high temperature of the heating device 2 during operation, thereby enhancing the safety of the heating device 2.

[0089] Furthermore, the width of the receiving groove 22 away from the PCB board 25 is smaller than the width of the receiving groove 22 close to the PCB board 25.

[0090] Understandably, the narrower upper width of the receiving slot 22 provides a more spacious initial space for placing the mosquito coil, making it easier for the user to align and insert the mosquito coil into the receiving slot 22, and then push the remaining part of the mosquito coil into the receiving slot 22 to complete the installation of the mosquito coil, which greatly improves the ease of use of the heating device 2.

[0091] Understandably, due to the setting of the pad 24, when the mosquito coil is inserted into the opening of the receiving groove 22 but not fully pushed into the interior, the part of the mosquito coil that has been placed in the receiving groove 22 comes into contact with the pad 24 and is heated, thereby ensuring that the heating device 2 can still achieve the mosquito repelling effect when the mosquito coil is not fully inserted, thus improving the practicality of the heating device 2.

[0092] Furthermore, the heating structure 23 is a ceramic heating element, and there are gaps between the periphery of the ceramic heating element and the inner wall of the slot 255.

[0093] Specifically, in this embodiment, the heating structure 23 is a circular ceramic heating element, and the slot 255 is a square hole.

[0094] Understandably, heating elements made of ceramic have good thermal conductivity, which can quickly and evenly transfer heat to the surface of the ceramic heating element, thereby improving the heating effect of the heating structure 23.

[0095] Understandably, the design of a certain gap between the PCB board 25 and the heating structure 23 avoids direct contact between the two, which helps to reduce the impact of the heat generated by the heating structure 23 during operation on the PCB board 25 and the circuit modules and electronic components on it, and improves the functional stability of the heating device 2.

[0096] Furthermore, the housing 21 has a wire hole corresponding to the wire body 3, and the wire body 3 passes through the wire hole to exit the heating device 2; the two ends of the wire body 3 near the heating device 2 are provided with locking members, and the width of the locking members is greater than the diameter of the wire hole; the two ends of the PCB board 25 near the wire body 3 are provided with grooves corresponding to the locking members, and the locking members are engaged in the limiting space formed by the grooves and the housing 21.

[0097] When the data cable 1 is plugged in and unplugged from the plug 4, the cable body 3 is pulled; when the cable body 3 tends to move relative to the heating device 2, there is a physical impact of pulling or squeezing at the electrical connection between the cable body 3 and the PCB board 25, which may cause the electrical connection between the two to break.

[0098] Understandably, when the cable 3 moves away from the PCB board 25, the locking component abuts against the inner wall of the housing 21 and hinders the movement of the cable 3, thereby preventing the cable 3 from being pulled at the electrical connection point between the cable 3 and the PCB board 25, greatly reducing the possibility of the electrical connection between the two being broken, and effectively improving the functional stability of the data cable 1.

[0099] Understandably, when the groove moves towards the PCB board 25, it abuts against the locking component and hinders the movement of the wire body 3, thereby preventing the electrical connection between the wire body 3 and the PCB board 25 from being squeezed, greatly reducing the possibility of the electrical connection between the two being broken, and effectively improving the functional stability of the data line 1.

[0100] Specifically, in this embodiment, the locking component is a cuboid, and the groove is correspondingly formed into a rectangular hole; more specifically, the four corners of the cuboid locking component are rounded.

[0101] Furthermore, the second control module 252 includes at least one switch button 256, and the housing 21 is provided with a switch pressing member 211 corresponding to the switch button 256; when the switch pressing member 211 is pressed, the switch pressing member 211 moves toward the PCB board 25 and presses the switch button 256.

[0102] Specifically, in this embodiment, the heating device 2 is provided with a switch button 256 and a corresponding switch pressing member 211.

[0103] Understandably, the setting of the switch button 256 facilitates the user's active control of the working state of the heating device 2, and the user can control the heating device 2 by pressing the switch button 211 to abut the switch button 256, which facilitates the user's switch operation and allows the user to get intuitive operation feedback, thereby enhancing the operation convenience and ease of use of the heating device 2.

[0104] Furthermore, the heating device 2 is provided with at least one indicator light 26, which is electrically connected to the PCB board 25.

[0105] Specifically, in this embodiment, the heating device 2 is provided with three indicator lights 26, and all three indicator lights 26 are LED lights.

[0106] More specifically, in this embodiment, the indicator light 26 is disposed on the side of the PCB board 25 where the switch button 256 is disposed, and the housing 21 has a through hole corresponding to the indicator light 26 to allow light to pass through.

[0107] Understandably, the indicator light 26 allows users to intuitively judge the working status of the heating device 2 by observing its status, thus making the working status of the heating device 2 visible. This makes it easier for users to adjust the usage of the data cable 1 or switch the current status of the heating device 2 based on its current working status, thereby improving the usability of the data cable 1.

[0108] Understandably, the indicator light 26 also serves to remind the user whether the heating device 2 is working, preventing the user from making mistakes during the heating process and causing burns, thus improving the safety of the data cable 1.

[0109] More specifically, the second control module 252 can actively control the lighting status, lighting duration and brightness of the indicator light 26, so that the indicator light 26 can be used as a night light or breathing light, enhancing the practicality and aesthetics of the data cable 1.

[0110] Compared with the prior art, the data cable of this utility model has the following advantages:

[0111] 1. The data cable of this utility model includes a heating device, which comprises a housing, at least one receiving slot formed on the housing, a PCB board disposed in the internal space formed by the housing, and a heating structure electrically connected to the PCB board; the PCB board has a slot corresponding to the receiving slot, and the heating structure is embedded in the slot; 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 two plugs, wherein at least one plug is located at one end of the cable body and electrically connected to the cable body, and at least one plug is located at the other end of the cable body and electrically connected to the cable body. By designing a slot in the PCB board, the heating structure is embedded in the slot, which greatly reduces the total volume occupied by the heating structure and the PCB board in the internal space of the housing, which is conducive to making a smaller heating device and improving the portability of the data cable.

[0112] 2. The receiving groove of this utility model is provided with a pad, which covers the groove hole. One side of the pad is exposed in the receiving groove, and the other side contacts the heating structure. By setting the pad to separate the PCB board and the mosquito coil, the pad provides support when the mosquito coil is placed in the receiving groove, and at the same time protects the PCB board and the heating structure embedded in the groove hole. This prevents direct contact and relative movement between the PCB board and the mosquito coil during insertion, removal, or use, which could lead to scratches or damage to the PCB board or the heating structure. This improves the functional stability and service life of the PCB board and the heating structure.

[0113] 3. In this invention, the edge of the PCB board near the opening of the receiving groove is the first side, and the edge of the housing near the first side is the second side. The two ends of the pad near the first side are bent along a plane parallel to the first side to form a protective wall, which is sandwiched between the first and second sides. Through this protective wall design, direct contact between the first and second sides is blocked, preventing direct friction or collision that could damage the PCB board and affect its normal function. This significantly improves the functional stability and service life of the PCB board.

[0114] 4. The housing of this utility model has two receiving slots, which are respectively located on both sides of the PCB board; the heating structure is sandwiched between two pads; the height of the receiving slot located on one side of the PCB board is less than the height of the receiving slot located on the other side of the PCB board. By opening two opposite receiving slots on both sides of the heating structure, the heating structure can simultaneously heat the mosquito coils inserted in the two receiving slots, greatly improving the utilization rate of the heating structure; and the mosquito repelling effect and range that the heating device can achieve per unit time are greatly improved, making it suitable for use in large indoor or outdoor spaces.

[0115] 5. The inner wall of the housing of this utility model is provided with a first baffle and a second baffle, which define a mounting position and a first cavity and a second cavity located on both sides of the mounting position; the PCB board includes a first component area and a second component area located on both sides of the slot; the first component area is sealed in the first cavity, and the second component area is sealed in the second cavity. By setting the first component area and the second component area, which can be sealed in the first cavity and the second cavity respectively, the housing seals and protects the important circuit modules and structures on the PCB board, avoids external environmental factors from affecting the normal operation of the PCB board, and improves the functional stability and service life of the PCB board.

[0116] 6. The PCB board of this utility model integrates a first control module and a step-down module. The first control module is located in the first component area, and the connection points of the step-down module and the heating structure to the PCB board are located in the second component area. By isolating and sealing the working circuits of the first control module and the step-down module or heating structure, the signal crosstalk that may occur between the first control module and the working circuit is effectively avoided, greatly improving the functional stability of each module.

[0117] 7. In this invention, the pad abuts against the first baffle on one side and against the second baffle on the other side. The PCB board and heating structure are sealed within a sealed cavity formed by the first baffle, the second baffle, and the pad. By setting the edge of the pad to abut against the first and second baffles, the two baffles and the pad form a sealed cavity, jointly protecting the PCB board and heating structure within the sealed cavity. This prevents damage to the PCB board or heating structure from external environmental factors such as splashing water or collisions, thus avoiding malfunctions and significantly enhancing the stability and service life of the heating device.

[0118] 8. A limiting member is provided on the inner wall of the receiving groove on the side away from the PCB board. The limiting member is strip-shaped and protrudes from both ends towards the center towards the PCB board. When the mosquito coil is inserted into the receiving groove, the limiting member abuts against the mosquito coil. Through the abutting relationship between the limiting member and the mosquito coil, the mosquito coil is prevented from accidentally falling off due to external forces such as shaking during the operation of the heating device, thus affecting the mosquito repellent effect of the heating device.

[0119] 9. A heat insulation structure is fitted onto the shell of this utility model. This heat insulation structure prevents users from being burned by the high temperature of the heating device during operation, thus enhancing the safety of the heating device.

[0120] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
