During the assembly of the first assembly component and the second assembly component, if the installation position of the ground wire is located inside the shell, it will make the assembly difficult.

At the same time, the first crimping rod and the second crimping rod of the crimping part cooperate with the first clamping rod and the second clamping rod of the clamping part to fix the ground wire, which can reduce the influence of the size of the ground wire on the fixed structure. At the same time, the fixed installation of the ground wire can be ensured to prevent the ground wire from excessive shaking and excessive bending, thereby improving the safety of the heating equipment.

The conductive sheet 140 is connected to the cable 130 , and the conductive sheet 140 is in contact with the shell 120 . The first connecting member 150 is passed through the conductive sheet 140 and is screwed into the first mounting hole 125 .

[0083] In this embodiment, the shell 120 is provided with a first mounting hole 125, and the heating device 100 also includes a conductive sheet 140 and a first connecting member 150. The conductive sheet 140 is connected to the cable 130, and the conductive sheet 140 is in contact with the shell 120. The first connecting member 150 is passed through the conductive sheet 140 and is screwed into the first mounting hole 125. Then, the first connecting member 150 can be connected to the cable 130 through the conductive sheet 140. It is no longer necessary to reserve a ground wire 132 on the shell 120, and the ground wire 132 can be electrically connected to the shell 120. No additional wiring steps are required, thereby reducing the installation steps of the heating device 100.

[0084] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0085] The base assembly 210 further includes a heating element 240, which is disposed on the base 110; the base 110 is a plastic part, the base assembly 210 is a first assembly component 260, the housing 120 is a metal part, the housing 120 is a second assembly component 270, the housing 120 is connected to the base 110 so that the first assembly component 260 and the second assembly component 270 are fixedly connected, and the heating element 240 and the controller 220 are accommodated in the chamber formed by the base 110 and the housing 120, and the ground wire 132 is in contact with the housing 120 so that the ground wire 132 is electrically connected to the housing 120. Among them, the first assembly component 260 includes but is not limited to only the controller 220, the heating element 240 and the base 110, and in some embodiments, it also includes a connecting member for assembling various components. In some embodiments, the controller 220, the heating element 240 and the base 110 include multiple components. For example, the heating element 240 is not limited to a heating tube. In some embodiments, the heating element 240 also includes a heating element bracket. The second assembly component 270 includes but is not limited to only the shell 120. In some embodiments, the shell 120 includes a detachable air outlet component.

[0086] In this embodiment, the base assembly 210 further includes a heating element 240 , and the heating element 240 is disposed on the base 110 .

[0087] When assembling the heating device 100, since the base assembly 210 is the first assembly assembly 260, the plastic base can be used as a carrier for installing the controller 220 and the heating element 240, that is, the controller 220, the heating element 240 and the base 110 can be assembled into the first assembly assembly 260, and the shell 120 is a metal part, and the shell 120 can be used as the second assembly assembly 270. After the first assembly assembly 260 is assembled, the metal shell can be assembled to the first assembly assembly 260, and the metal shell and the plastic base can be connected by a connector, such as a screw for fixing, so that the first assembly assembly 260 and the second assembly assembly 270 can be assembled and fixed, and the heating element 240 and the controller 220 are accommodated in the chamber formed by the base 110 and the shell 120, and the ground wire 132 is in contact with the shell 120 so that the ground wire 132 and the shell 120 are electrically connected. During the assembly of the first assembly component 260 and the second assembly component 270, if the installation position of the ground wire 132 is located inside the shell 120, it will make the assembly difficult. Therefore, the ground wire 132 is directly connected to the shell 120, so that the wiring position of the ground wire 132 is located outside the heating device 100, which reduces the assembly difficulty of the ground wire 132 and simplifies the assembly process of the ground wire 132; and the controller 220, the heating element 240 and the base 110 are modularly integrated into the first assembly component 260, and then the first assembly component 260 and the second assembly component 270 formed by the shell 120 are fixedly connected to improve the assembly efficiency. At the same time, when integrating the first assembly component 260, since the base 110 is a plastic part, the base 110 can be produced according to the size of the controller 220 and the heating element 240, which improves the adaptability of the base 110. Since the shell 120 is a metal part, the ground wire 132 can be directly electrically connected to the shell 120, reducing the wiring cost.

[0088] By setting the first assembly component 260 and the second assembly component 270, the modular assembly of the base component 210 and the shell 120 can be achieved, thereby improving the assembly efficiency. When assembling the heating device 100, the heating element 240 and the controller 220 can be installed on the base component 210, and then the base component 210 and the shell 120 are assembled. Since the ground wire 132 is in contact with the shell 120, while improving the assembly efficiency, it is no longer necessary to reserve the ground wire 132 on the shell 120, which can ensure that the shell 120 of the heating device 100 is connected to the ground wire 132, while simplifying the structure of the shell 120 on the heating device 100. At the same time, since the ground wire 132 is assembled on the base 110, the ground wire 132 can be electrically connected to the shell 120 through the installation of the base 110 and the shell 120, without the need for additional wiring steps, thereby reducing the installation steps of the heating device 100 and reducing the installation cost.

[0089] Specifically, the ground wire 132 has a ground wire cable and an insulating shell inside, and the end of the ground wire 132 is connected to the conductive sheet 140, and the end of the conductive sheet 140 can be crimped with the end of the ground wire 132 through the insulating shell, thereby forming an electrical connection between the ground wire 132 and the conductive sheet 140.

[0090] The first assembly component is all the structural parts of the base component 210 , and may also be part of the structural parts of the base component 210 .

[0091] In the embodiment of the present utility model, Figure 4 and Figure 5 As shown, a heating device 100 is provided, including a base 110, a shell 120 and a cable 130, the shell 120 is arranged on the base 110, the cable 130 is arranged on the base 110, the cable 130 includes a ground wire 132, and the ground wire 132 is electrically connected to the shell 120.

[0092] A heating device 100 provided in the present application includes a base 110, a shell 120 and a cable 130. The shell 120 is arranged on the base 110, which can ensure the structural stability and safety of the heating device 100 and also make the heating device 100 easier to place and use. The cable 130 is arranged on the base 110, and the cable 130 includes a ground wire 132, and the ground wire 132 is electrically connected to the shell 120. By setting the ground wire 132, the safety of the heating device 100 during operation can be improved, the hidden danger of leakage after the heating device 100 is connected to the power supply can be avoided, and the influence of static electricity on the normal operation of the heating device 100 can be reduced. Since the ground wire 132 is arranged in the cable 130, after the shell 120 and the base 110 are assembled, the ground wire 132 can be electrically connected to the base 110, and then it is no longer necessary to reserve the ground wire 132 on the shell 120. It can ensure that the shell 120 of the heating device 100 is connected to the ground wire 132, and at the same time, the structure of the shell 120 on the heating device 100 is simplified. At the same time, since the ground wire 132 is assembled on the base 110, the ground wire 132 can be electrically connected to the shell 120 through the installation of the base 110 and the shell 120, without the need for additional wiring steps, thereby reducing the installation steps of the heating device 100 and reducing the installation cost.

[0093] Furthermore, after the shell 120 is fixedly connected to the base 110 , the ground wire 132 is electrically connected to the shell 120 , so that static electricity and leakage current on the heating device 100 can be introduced into the ground, thereby improving the safety of the heating device 100 .

[0094] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0095] The shell 120 includes a first body 121 and a first mounting portion 123 . The first body 121 is connected to the base 110 . The first mounting portion 123 is disposed on the first body 121 and located on a side of the first body 121 close to the base 110 . The ground wire 132 is electrically connected to the first mounting portion 123 .

[0096] In this embodiment, the shell 120 includes a first body 121 and a first mounting portion 123. The first body 121 is connected to the base 110, which can enhance the stability of the shell 120 structure and also improve the strength of the connection between the shell 120 and the base 110 when the heating device 100 is installed. Since the first mounting portion 123 is arranged on the first body 121, located on the side of the first body 121 close to the base 110, the ground wire 132 is electrically connected to the first mounting portion 123. After the shell 120 and the base 110 are installed to each other, the ground wire 132 can be electrically connected to the shell 120 through the first mounting portion 123 to ensure the safety of the heating device 100. At the same time, the difficulty of wiring the ground wire 132 and the shell 120 can be reduced, simplifying the assembly process.

[0097] Furthermore, by electrically connecting the first mounting portion 123 provided on the housing 120 to the ground wire 132, there is no need to reserve the ground wire 132 on the housing 120, thereby simplifying the structure of the housing 120. At the same time, when assembling the heating device 100, no additional wiring steps are required, which simplifies the installation steps of the heating device 100 and improves the assembly efficiency of the housing 120 and the base 110 of the heating device 100.

[0098] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0099] The first mounting portion 123 is a first mounting hole 125 . The heating device 100 further includes a conductive sheet 140 and a first connecting member 150 . The conductive sheet 140 is connected to the ground wire 132 . The conductive sheet 140 is provided with a second mounting hole 142 . The second mounting hole 142 is opposite to the first mounting hole 125 . The first connecting member 150 is passed through the first mounting hole 125 .

[0100] In this embodiment, the first mounting portion 123 is set as the first mounting hole 125, which can facilitate the connection between the ground wire 132 and the first mounting portion 123. At the same time, the heating device 100 also includes a conductive sheet 140 and a first connector 150. The conductive sheet 140 is connected to the ground wire 132. By arranging the conductive sheet 140 on the ground wire 132, the difficulty of assembling the ground wire 132 and the first mounting portion 123 can be reduced. A second mounting hole 142 is provided on the conductive sheet 140, and the second mounting hole 142 is provided opposite to the first mounting hole 125. The first connecting member 150 is passed through the first mounting hole 125. After the first mounting hole 125 and the second mounting hole 142 are relatively provided, the first connecting member 150 is passed through the first mounting hole 125 and the second mounting hole 142, so as to realize the connection between the conductive sheet 140 and the first mounting portion 123, and then realize the connection between the ground wire 132 and the shell 120, thereby reducing the difficulty of assembling the ground wire 132 and the shell 120, simplifying the wiring steps, and also reducing the difficulty of installing the heating device 100.

[0101] Furthermore, the shell 120 and the ground wire 132 are connected by using the first connecting member 150, which can stabilize the connection structure between the ground wire 132 and the shell 120. At the same time, the first connecting member 150 can adopt a standardized design, thereby improving the versatility of the heating device 100 and facilitating the replacement and maintenance of the heating device 100.

[0102] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0103] The heating device 100 further includes a clamping portion 160 , which is connected to the base 110 and is located on a side of the base 110 away from the housing 120 ; the conductive sheet 140 is clamped to the clamping portion 160 .

[0104] In this embodiment, the heating device 100 also includes a clamping portion 160, which is connected to the base 110 and is located on the side of the base 110 away from the shell 120. By arranging the clamping portion 160 on the base 110, the difficulty of assembling the heating device 100 can be reduced. The connection structure of the clamping portion 160 is simple and easy to operate, and it can also play a role in installation guidance, reducing the time cost of production and installation. At the same time, the clamping portion 160 can also improve the stability of the internal structure of the heating device 100. Since the conductive sheet 140 is clamped to the clamping portion 160, the installation of the conductive sheet 140 is more convenient and quick, and the installation structure can also be simplified, thereby reducing the production cost. Furthermore, by arranging the clamping portion 160 to fix the conductive sheet 140, the difficulty of assembling the cable 130 can be simplified, and the shaking of the cable 130 inside the heating device 100 can be reduced, thereby improving the stability and safety of the structure of the heating device 100.

[0105] Furthermore, if Figure 6 As shown, during maintenance and inspection of the heating device 100 , the conductive sheet 140 installed by snap-fitting can facilitate the removal of the conductive sheet 140 , which is beneficial for maintenance and replacement of the device and further improves the user experience of the heating device 100 .

[0106] Specifically, Figure 7 As shown, the ground wire 132 can also be fixed on the clamping part 160, and the number of the clamping parts 160 can be two, which can be adjusted according to needs during the production and installation of the heating device 100.

[0107] Specifically, by providing the clamping portion 160 , the ground wire 132 and the conductive sheet 140 can be clamped on the first body 121 respectively.

[0108] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0109] The first mounting portion 123 is a terminal post 126 , and at least a portion of the ground wire 132 is wound around the terminal post 126 .

[0110] In this embodiment, the first mounting portion 123 is a terminal post 126, and at least a portion of the ground wire 132 is wound around the terminal post 126, which can ensure a stable connection of the ground wire 132, and ensure that the ground wire 132 can conduct static electricity and leakage current of the device housing to the ground, thereby improving the safety of the device. At the same time, winding at least a portion of the ground wire 132 around the terminal post 126 can reduce the volume occupied by the ground wire 132 and optimize the space inside the heating device 100. At the same time, the ground wire 132 wound around the terminal post 126 can improve the neatness of the installation of the ground wire 132, avoid the ground wire 132 from being damaged due to bending and transition, and further improve the safety effect of the heating device 100.

[0111] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0112] The base 110 includes a second body 112 and a second mounting portion 113 . The second mounting portion 113 is connected to the second body 112 and is located at a side of the second body 112 close to the housing 120 . The ground wire 132 is connected to the second mounting portion 113 .

[0113] In this embodiment, the base 110 includes a second body 112 and a second mounting portion 113. The second mounting portion 113 is connected to the second body 112 and is located on a side of the second body 112 close to the shell 120. The ground wire 132 is connected to the second mounting portion 113. Firstly, the provision of the second body 112 and the second mounting portion 113 can enhance the stability and structural strength of the base 110 structure. By providing the second mounting portion 113 connected to the second body 112, the installation space of the base 110 can be optimized. Connecting the ground wire 132 to the second mounting portion 113 can improve the safety of the heating device 100. The ground wire 132 can conduct static electricity on the shell 120 of the heating device 100 to the earth through the second mounting portion 113, thereby improving the stability of the heating device 100 during operation. At the same time, it also prevents users from getting electric shocks when using the heating device 100, effectively preventing electrical failures and safety hazards.

[0114] By electrically connecting the ground wire 132 to the second body 112, the ground wire 132 can be electrically connected to the base 110. Therefore, when assembling the base 110 and the shell 120, there is no need to reserve an additional ground wire 132 on the shell 120. It can also ensure that the outer shell of the heating device 100 is electrically connected to the ground wire 132 while simplifying the structure of the shell 120 on the heating device 100. At the same time, since the ground wire 132 is assembled on the base 110, the ground wire 132 can be electrically connected to the shell 120 through the installation of the base 110 and the shell 120. No additional wiring steps are required, which reduces the installation steps of the heating device 100 and reduces the installation cost.

[0115] Specifically, the cable 130 may be directly electrically connected to the second installation portion 113 , and the direct electrical connection between the cable 130 and the second installation portion 113 is equivalent to the direct electrical connection between the ground wire 132 and the second installation portion 113 .

[0116] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0117] The second mounting portion 113 includes at least two clamping portions 170 . The at least two clamping portions 170 are respectively connected to the second body 112 . A first gap 172 is defined between the at least two clamping portions 170 . The ground wire 132 is located in the first gap 172 .

[0118] In this embodiment, the second mounting portion 113 includes at least two clamping portions 170, and the at least two clamping portions 170 are respectively connected to the second body 112. There is a first gap 172 between the at least two clamping portions 170, and the ground wire 132 is located in the first gap 172, which improves the assembly efficiency of the ground wire 132 and reduces the installation difficulty. The two clamping portions 170 limit the position of the ground wire 132, so that the ground wire 132 can be fixedly installed, and the ground wire 132 can be effectively prevented from being damaged by external pollutants, thereby improving the safety of the ground wire 132.

[0119] Furthermore, the provision of the clamping portion 170 can improve the fixing strength of the second mounting portion 113 to the ground wire 132 , while also simplifying the assembly steps.

[0120] Furthermore, since the two clamping parts 170 are independently provided, they can be adjusted and replaced according to the needs of the heating device 100, and thus can be suitable for different scenarios.

[0121] Furthermore, the distance between the two clamping portions 170 can be set to be smaller than the wire diameter of the ground wire 132. When the ground wire 132 is installed between the two clamping portions 170, since the distance between the clamping portions 170 is smaller than the wire diameter, the shell 120 of the ground wire 132 will be squeezed and then elastically deformed. The deformation of the outer surface of the ground wire 132 can make the ground wire 132 stably installed on the base 110. At the same time, the assembly pressure generated by the interference fit between the clamping portions 170 and the ground wire 132 can ensure the stability and reliability of the ground wire 132 line, and can also reduce the falling off of the ground wire 132, thereby improving the electrical performance.

[0122] Furthermore, the number of the clamping parts 170 can be set to three, and the distribution of the clamping parts 170 can be set on one side of the ground wire 132 and two clamping parts 170 on the other side of the ground wire 132, which can improve the stability of the ground wire 132 after assembly.

[0123] Furthermore, the number of the clamping parts 170 may be four, and the distribution of the clamping parts 170 may be such that two clamping parts 170 are provided on each side of the ground wire 132 , thereby improving the stability of the ground wire 132 after assembly.

[0124] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0125] The second mounting portion 113 further includes at least one crimping portion 180 , and the at least one crimping portion 180 is connected to the clamping portion 170 ; the ground wire 132 is located between the crimping portion 180 and the second body 112 .

[0126] In this embodiment, the second mounting portion 113 further includes at least one crimping portion 180, and at least one crimping portion 180 is connected to the clamping portion 170; the ground wire 132 is located between the crimping portion 180 and the second body 112. The crimping portion 180 and the second body 112 can fix the ground wire 132, which can further improve the stability of the ground wire 132 after installation. At the same time, the fixing structure of the crimping portion 180 can be applicable to ground wires 132 of multiple sizes, and can limit the position of the ground wire 132 while avoiding excessive bending of the ground wire 132, thereby improving the safety of the heating device 100.

[0127] Specifically, the crimping parts 180 and the clamping parts 170 can be set to the same number to facilitate the assembly of the ground wire 132. The crimping parts 180 and the clamping parts 170 can also be set to different numbers, and the crimping parts 180 and the clamping parts 170 can be set according to actual needs.

[0128] Specifically, when the number of the crimping portions 180 and the number of the clamping portions 170 are the same, each clamping portion 170 is correspondingly provided with a crimping portion 180 .

[0129] Specifically, when the crimping portion 180 and the clamping portion 170 are set to different numbers, one of the two clamping portions 170 can be provided with a crimping portion 180, and the other clamping portion 170 does not need to be provided with a crimping portion 180, which can ensure the stable assembly of the ground wire 132 while reducing costs.

[0130] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0131] The clamping portion 170 includes a first clamping rod 174 and a second clamping rod 176; the first end of the first clamping rod 174 is connected to the second body 112; the first end of the second clamping rod 176 is connected to the second body 112; the crimping portion 180 includes a first crimping rod 182 and a second crimping rod 184; the first end of the first crimping rod 182 is connected to the second end of the first clamping rod 174, and the second end of the first crimping rod 182 extends toward the second clamping rod 176; the first end of the second crimping rod 184 is connected to the second end of the second clamping rod 176, and the second end of the second crimping rod 184 extends toward the first clamping rod 174, and a second gap 186 is provided between the second end of the second crimping rod 184 and the second end of the first crimping rod 182.

[0132] In this embodiment, the clamping portion 170 includes a first clamping rod 174 and a second clamping rod 176; the first end of the first clamping rod 174 is connected to the second body 112 to improve the structural strength of the first clamping rod 174. The first end of the second clamping rod 176 is connected to the second body 112 to improve the structural strength of the second clamping rod 176. Since the first clamping rod 174 and the second clamping rod 176 are respectively connected to the second body 112, the clamping portion 170 can form a stable clamping structure through the first clamping rod 174 and the second clamping rod 176, so that the ground wire 132 can be firmly fixed at a preset position, reducing the shaking and displacement of the ground wire 132 in the heating device 100.

[0133] The crimping portion 180 includes a first crimping rod 182 and a second crimping rod 184. The first end of the first crimping rod 182 is connected to the second end of the first clamping rod 174, and the second end of the first crimping rod 182 extends toward the second clamping rod 176. The first end of the second crimping rod 184 is connected to the second end of the second clamping rod 176, and the second end of the second crimping rod 184 extends toward the first clamping rod 174. The ground wire 132 can be fixed so that the ground wire 132 is firmly installed on the base 110. At the same time, the first crimping rod 182 and the second crimping rod 184 of the crimping portion 180 cooperate with the first clamping rod 174 and the second clamping rod 176 of the clamping portion 170 to fix the ground wire 132, which can reduce the influence of the size of the ground wire 132 on the fixed structure. At the same time, the fixed installation of the ground wire 132 can be ensured to prevent the ground wire 132 from excessive shaking and excessive bending, thereby improving the safety of the heating device 100.

[0134] A second gap 186 is defined between the second end of the second crimping rod 184 and the second end of the first crimping rod 182 , which can facilitate the assembly of the ground wire 132 and reduce the difficulty of installing the ground wire 132 .

[0135] Specifically, the ground wire 132 can be first fixed in the first gap 172 through the fixing structure of the crimping portion 180 and the clamping portion 170 , and then the base 110 can be fixed on the shell 120 to electrically connect the ground wire 132 to the shell 120 .

[0136] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0137] The distance between the second end of the second crimping rod 184 and the second end of the first crimping rod 182 is smaller than the wire diameter of the ground wire 132 .
