Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an automobile ignition coil. Background Art

[0002] The car ignition coil is a key component in the car ignition system. The main function of the car ignition coil is to convert low-voltage direct current (usually 12V from the car battery) into high-voltage pulse electrical energy, thereby generating high energy sufficient to generate an electric spark between the spark plug electrodes to ignite the mixed gas in the engine combustion chamber and enable the engine to operate normally.

[0003] The ignition coil in the related technology will form a large amount of carbon deposits on the spark plug after a certain amount of accumulated working time. The carbon deposits will not only prevent the high voltage electricity generated by the secondary winding of the ignition coil from being released in time to form voltage feedback, but also cause the spark plug to ignite poorly and the mixture to fail to burn fully and timely, so that the ignition coil needs to provide higher energy or longer ignition time to try to ignite the mixture during ignition, causing the ignition coil to be in a high-load state for a long time. The high-load state will generate more heat, which will damage the insulating materials and electronic components inside the ignition coil. The poor stability of the ignition coil will lead to low service life and working efficiency. Summary of the invention

[0026] The car ignition coil is a key component in the car ignition system. The main function of the car ignition coil is to convert low-voltage direct current (usually 12V from the car battery) into high-voltage pulse electrical energy, thereby generating high energy sufficient to generate an electric spark between the spark plug electrodes to ignite the mixed gas in the engine combustion chamber and enable the engine to operate normally.

[0027] The ignition coil in the related technology will form a large amount of carbon deposits on the spark plug after a certain amount of accumulated working time. The carbon deposits will not only prevent the high voltage electricity generated by the secondary winding of the ignition coil from being released in time to form voltage feedback, but also cause the spark plug to ignite poorly and the mixture to fail to burn fully and timely, so that the ignition coil needs to provide higher energy or longer ignition time to try to ignite the mixture during ignition, causing the ignition coil to be in a high-load state for a long time. The high-load state will generate more heat, which will damage the insulating materials and electronic components inside the ignition coil. The poor stability of the ignition coil will lead to low service life and working efficiency.

[0028] Based on this, in order to improve the problem in the related art that carbon deposits are formed on the spark plug, resulting in voltage feedback and the ignition coil requiring higher energy or longer ignition time to ignite the mixture, which causes the internal insulating materials and electronic components of the ignition coil to be damaged due to high load conditions, the embodiments of the present application provide the following solution.

[0029] See also Figure 1 The embodiment of the present application provides an automobile ignition coil 100, which includes a high voltage generating device 10 and a carbon deposit cleaning mechanism 20, wherein: The high voltage generating device 10 includes a transformer mechanism 11 and a high voltage conducting mechanism 12 . The high voltage conducting mechanism 12 is electrically connected to the transformer mechanism 11 . The high voltage conducting mechanism 12 includes a first mounting portion 121 and a second mounting portion 122 insulated from each other. The first mounting portion 121 is used to mount the spark generating device 200 .

[0030] The carbon deposit cleaning mechanism 20 is located below the high voltage conducting mechanism 12 , and the carbon deposit cleaning mechanism 20 is electrically connected to the second mounting portion 122 ; the carbon deposit cleaning mechanism 20 extends to the ignition position of the spark generating device 200 .

[0031] Among them, the high-voltage transmission mechanism 12 is used to electrically connect the transformer mechanism 11 to the first mounting part 121 or the second mounting part 122 selectively; when the transformer mechanism 11 is electrically connected to the first mounting part 121, the high voltage generated by the transformer mechanism 11 is transmitted to the spark generating device 200 through the first mounting part 121, so that the spark generating device 200 generates an electric spark to ignite the mixed gas; when the transformer mechanism 11 is electrically connected to the second mounting part 122, the high voltage generated by the transformer mechanism 11 is transmitted to the carbon deposit cleaning mechanism 20 through the second mounting part 122, so that the carbon deposit cleaning mechanism 20 cleans the carbon deposits on the spark generating device 200.

[0032] It can be understood that the spark generating device 200 can be various types of spark plugs. The transformer mechanism 11 can be a component that can convert low voltage into high voltage, for example, it can be a transformer, and the transformer is composed of a primary coil, a secondary coil and an iron core, etc., but it is not limited to this. The high-voltage transmission mechanism 12 is a structure that can transmit high voltage to the position of the spark generating device 200, for example, it can be a structure having multiple conduction blocks and a conductive plate or conductive sheet that can selectively conduct with the conduction blocks, etc., but it is not limited to this. The carbon deposit cleaning mechanism 20 is a structure that can use high voltage to perform high-pressure cleaning on the carbon deposits on the spark generating device 200, etc., but it is not limited to this.

[0033] From the above, it can be seen that in the automobile ignition coil 100 provided in the embodiment of the present application, the high-voltage transmission mechanism 12 is electrically connected to the transformer mechanism 11, and the high voltage generated by the transformer mechanism 11 can be transmitted through the high-voltage transmission mechanism 12; the first mounting portion 121 and the second mounting portion 122 are insulated from each other and the first mounting portion 121 is used to install the spark generating device 200, which can prevent the high voltage from being simultaneously transmitted to the second mounting portion 122 when the high voltage is transmitted to the spark generating device 200 through the first mounting portion 121, thereby reducing damage to the ignition coil and the engine, and helping to improve safety. When the transformer mechanism 11 is electrically connected to the first mounting portion 121, the transformer mechanism 11 works to generate high voltage, and transmits the generated high voltage to the spark generating device 200 through the first mounting portion 121, and the spark generating device 200 generates electric sparks to ignite the mixed gas, so that it ignites normally; when the transformer mechanism 11 is electrically connected to the second mounting portion 122, the transformer mechanism 11 is electrically connected to the second mounting portion 122, and the transformer mechanism 11 generates high voltage, which is transmitted to the carbon deposit cleaning mechanism 20 through the second mounting portion 122, so that the carbon deposit cleaning mechanism 20 uses the received high voltage to clean the conductor 12 62 Cleaning the carbon deposits on the spark generating device 200 can reduce the carbon deposits on the spark generating device 200 and reduce the situation of poor ignition caused by excessive carbon deposits on the spark generating device 200, so as to improve the ignition efficiency; at the same time, through the setting of the carbon deposit cleaning mechanism 20, the carbon deposits on the spark generating device 200 can be effectively removed, and the ignition coil can be kept in a high load state for a long time as much as possible, so as to prevent the high load state from generating more heat and damaging the insulating materials and electronic components inside the ignition coil, thereby extending the service life of the ignition coil and improving the stable operation of the engine.

[0034] In some embodiments, please refer to Figure 1 and Figure 2 The high voltage transmission mechanism 12 further includes an insulating housing 123, a controllable conductive member 124 and a driving mechanism 125, wherein: The insulating housing 123 is disposed on the transformer mechanism 11 ; the first mounting portion 121 and the second mounting portion 122 are disposed on the insulating housing 123 at intervals.

[0035] The electrical connection portion 126 is disposed on the transformer mechanism 11 and is electrically connected to the transformer mechanism 11 .

[0036] The controllable conductive member 124 is movably disposed in the insulating housing 123 , a first end of the controllable conductive member 124 is electrically connected to the electrical connection portion 126 , and a second end of the controllable conductive member 124 is selectively electrically connected to the first mounting portion 121 or the second mounting portion 122 .

[0037] The power output end of the driving mechanism 125 is connected to the controllable conductive member 124 , and is used to drive the second end of the controllable conductive member 124 to move to be electrically connected to the first mounting portion 121 or the second mounting portion 122 .

[0038] It can be understood that the insulating shell 123 is a structure that can insulate high voltage and accommodate the controllable conductive member 124 and / or the driving mechanism 125. The controllable conductive member 124 is a structure that can selectively control the electrical connection with the first mounting portion 121 or the second mounting portion 122, for example, it can be a structure that controls the conduction through a conductor and a contact part on the conductor, etc., but is not limited to this. The driving mechanism 125 is a component connected to the first mounting portion 121 or the second mounting portion 122 that can drive the controllable conductive member 124 to move, for example, it can be a micro linear motor or a micro telescopic motor, etc., but is not limited to this; wherein, the driving mechanism 125 can also be an integrated controller, which is wirelessly connected to the ECU, and the movement of the driving mechanism 125 can be controlled by the ECU. Among them, the first end of the controllable conductive member 124 is electrically connected to the electrical connecting part 126, and the connection method can be to connect the first end of the controllable conductive member 124 to the electrical connecting part 126 in a hinged manner. When switching the conductive path, the driving mechanism 125 pushes the second end of the controllable conductive member 124 to move to the position of the first mounting part 121 or the second mounting part 122 for contact conduction.

[0039] In this way, the insulating shell 123 is arranged on the clean conductor 1262 transformer mechanism 11 to prevent the high voltage from being lost through the insulating shell 123, thereby helping to improve safety; the second end of the controllable conductive member 124 is selectively electrically connected to the first mounting portion 121 or the second mounting portion 122, so that the driver can flexibly, freely choose and more conveniently clean the carbon deposits on the spark generating device 200. When the automobile is operating normally, the first end of the controllable conductive member 124 is electrically connected to the electrical connection part 126, and the driving mechanism 125 drives the second end of the controllable conductive member 124 to move to the position of the first mounting part 121 and electrically connect, so as to conduct the high voltage generated by the transformer mechanism 11 to the spark generating device 200 through the first mounting part 121, thereby causing the spark generating device 200 to generate an electric spark to ignite the mixed gas; when the automobile is in the ignition-off state, the first end of the controllable conductive member 124 is electrically connected to the electrical connection part 126, and the driving mechanism 125 drives the second end of the controllable conductive member 124 to move to the position of the second mounting part 122 and electrically connect, so as to conduct the high voltage generated by the transformer mechanism 11 to the carbon deposit cleaning mechanism 20 through the second mounting part 122, so as to use the high voltage to clean the carbon deposits on the cleaning conductor 1262 spark generating device 200. The cooperation between the controllable conductive member 124 and the driving mechanism 125 can reduce manual intervention, improve cleaning efficiency, and help to make the performance of the spark generating device 200 more stable and extend the service life of the ignition coil.

[0040] Optionally, in some embodiments, see Figure 2 and Figure 3 The controllable conductive member 124 includes an insulating connector 1241 and a switching component 1242. The insulating connector 1241 is located in the insulating housing 123; one end of the insulating connector 1241 is connected to the power output end of the driving mechanism 125. The switching component 1242 is located in the insulating housing 123 and connected to the other end of the insulating connector 1241.

[0041] The first end of the switching component 1242 is electrically connected to the electrical connection portion 126 , and the second end of the switching component 1242 is electrically connected to either the first mounting portion 121 or the second mounting portion 122 .

[0042] It can be understood that the insulating connector 1241 is a structure that can push the switching component 1242 to move in translation under the power of the driving mechanism 125, for example, it can be a shaft-like structure and made of ceramics, etc., but not limited to this. The switching component 1242 is a structure that can switch the current flow path, for example, it can be a conductor structure that can move in translation, etc., but not limited to this.

[0043] In this arrangement, one end of the insulating connector 1241 is connected to the power output end of the driving mechanism 125, and the switching component 1242 is connected to the other end of the insulating connector 1241, which helps to improve the accuracy and reliability of switching the current flow path; when the engine of the automobile needs to be ignited or the carbon deposits on the spark generating device 200 need to be cleaned, the driving mechanism 125 can drive the insulating connector 1241 to translate, and while the insulating connector 1241 translates, it drives the switching component 1242 to switch the current path to clean the carbon deposits on the spark generating device 200 or ignite the mixed gas. When it is necessary to clean the carbon deposits on the spark generating device 200, it can be more flexible, and it can be determined whether to clean it according to user needs, thereby improving operational flexibility.

[0044] Optionally, in some embodiments, see Figure 3The switching component 1242 includes a switching conductive member 12421, a first elastic member 12422 and a first contact member 12423. The switching conductive member 12421 is movably disposed in the insulating housing 123 and connected to the other end of the insulating connector 1241. One end of the first elastic member 12422 is fixedly connected to the second end of the switching conductive member 12421. One end of the first contact member 12423 is fixedly connected to the other end of the first elastic member 12422. The second end of the switching conductive member 12421 is electrically connected to the first mounting portion 121 or the second mounting portion 122 by selectively contacting the first contact member 12423, and when the second end of the switching conductive member 12421 is electrically connected to the first mounting portion 121 or the second mounting portion 122 by the first contact member 12423, the first end of the switching conductive member 12421 is electrically connected to the electrical connection portion 126.

[0045] It can be understood that the switching conductive member 12421 is a structure capable of switching the current flow path, such as a rectangular conductive block or a conductive body, but not limited thereto. The first elastic member 12422 is a structure capable of being compressed when subjected to pressure, such as a spring structure, but not limited thereto. The first contact member 12423 is a structure capable of conducting high voltage to the first mounting portion 121 or the second mounting portion 122, such as a conductive sheet or block, but not limited thereto.

[0046] With such arrangement, when the automobile engine needs to be ignited, the first end of the switching conductor 12421 is electrically connected to the electrical connection portion 126, and the second end of the switching conductor 12421 squeezes the first contact member 12423 through the first elastic member 12422, so as to be electrically connected through the first contact member 12423 contacting the first mounting portion 121, and at the same time, the high voltage is transmitted to the switching conductor 12421 through the electrical connection portion 126, and then transmitted to the first mounting portion 121 by the switching conductor 12421. When it is necessary to clean the carbon deposits on the spark generating device 200, the first end of the switching conductor 12421 is electrically connected to the electrical connection part 126, and the second end of the switching conductor 12421 squeezes the first contact member 12423 through the first elastic member 12422, so as to be electrically connected through the first contact member 12423 and the second mounting part 122. At the same time, the high voltage is transmitted to the switching conductor 12421 through the electrical connection part 126, and then transmitted to the second mounting part 122 by the switching conductor 12421; according to the needs of the driver, the high voltage can be flexibly switched by controlling the switching conductor 12421, so that the carbon deposits can be cleaned conveniently and the damage to other components can be minimized to increase the service life of the spark generating device 200.

[0047] Optionally, in some embodiments, see Figure 3, the switching conductive member 12421 is disposed in the insulating housing 123 for translational movement, and the switching member 1242 further includes a second elastic member 12424 and a second contact member 12425. One end of the second elastic member 12424 is fixedly connected to the first end of the switching conductive member 12421. One end of the second contact member 12425 is fixedly connected to the other end of the second elastic member 12424. When the second end of the switching conductive member 12421 is selectively electrically connected to the first mounting portion 121 or the second mounting portion 122 through the first contact member 12423, the first end of the switching conductive member 12421 is electrically connected to the electrical connection portion 126 through the second contact member 12425.

[0048] It can be understood that the second elastic member 12424 is a structure that can be compressed when subjected to pressure, such as a spring structure, but not limited thereto. The first contact member 12423 is a structure that can conduct high voltage to the first mounting portion 121 or the second mounting portion 122, such as a conductive sheet or block, but not limited thereto.

[0049] With such arrangement, when the automobile engine needs to be ignited or the carbon deposits on the spark generating device 200 need to be cleaned, when the first end of the switching conductor 12421 is electrically connected to the electrical connection part 126, the second elastic member 12424 is squeezed after being subjected to force, and the second contact member 12425 approaches the second elastic member 12424 to electrically connect the second contact member 12425 to the electrical connection part 126, and the second end of the switching conductor 12421 is electrically connected to the first mounting part 121 through the first contact member 12423, which can reduce interference and improve conduction efficiency. High voltage can be used to clean the carbon deposits on the spark generating device 200 to reduce the carbon deposits on the spark generating device 200 and minimize the situation of poor ignition of the spark generating device 200, thereby helping to improve the effect of igniting the mixed gas.

[0050] Optionally, in some embodiments, see Figure 3 The controllable conductive member 124 is disposed in the insulating housing 123 for translational movement, and the electrical connection portion 126 includes an ignition conductor 1261 and a cleaning conductor 1262, wherein: The ignition conductor 1261 is disposed on the insulating housing 123 and is disposed opposite to the first mounting portion 121 ; one end of the ignition conductor 1261 is electrically connected to the transformer mechanism 11 .

[0051] The clean conductor 1262 is disposed on the insulating housing 123 and is disposed opposite to the second mounting portion 122 ; one end of the clean conductor 1262 is electrically connected to the transformer mechanism 11 .

[0052] Among them, the ignition conductor 1261 and the cleaning conductor 1262 are arranged at intervals along the translation direction of the controllable conductive part 124; when the second end of the controllable conductive part 124 is electrically connected to the first mounting part 121, the first end of the controllable conductive part 124 is electrically connected to the other end of the ignition conductor 1261; when the second end of the controllable conductive part 124 is electrically connected to the second mounting part 122, the first end of the controllable conductive part 124 is electrically connected to the other end of the cleaning conductor 1262.

[0053] It can be understood that the ignition conductor 1261 is a structure capable of transmitting voltage to the spark generating device 200, and may be, for example, a rectangular conductor or a cylindrical conductor, etc., but is not limited thereto. The cleaning conductor 1262 is a structure capable of transmitting high voltage to the carbon deposit cleaning mechanism 20, and may be, for example, a cylindrical conductor or a square conductor, etc., but is not limited thereto. The controllable conductive member 124 is disposed in the insulating housing 123 in a translationally movable manner, and may be moved to the position of the ignition conductor 1261 or the cleaning conductor 1262.

[0054] With such arrangement, when the automobile engine needs to be ignited, the first end of the controllable conductive member 124 is electrically connected to the other end of the ignition conductor 1261, and the second end of the controllable conductive member 124 is electrically connected to the first mounting portion 121. At this time, the voltage generated by the transformer 11 is transmitted to the first end of the controllable conductive member 124 through the ignition conductor 1261, and then the voltage is transmitted to the first mounting portion 121 through the second end of the controllable conductive member 124. When the carbon deposits on the spark generating device 200 need to be cleaned, the first end of the controllable conductive member 124 is electrically connected to the other end of the cleaning conductor 1262, and the controllable conductive member 124 is electrically connected to the first mounting portion 121. The second end is electrically connected to the second mounting portion 122. At this time, the high voltage generated by the transformer mechanism 11 is transmitted to the first end of the controllable conductive member 124 through the cleaning conductor 1262, and then the voltage is transmitted to the second mounting portion 122 through the second end of the controllable conductive member 124. This allows rapid switching of the ignition and cleaning functions, thereby reducing engine maintenance time and improving vehicle operating efficiency. Since the ignition conductor 1261 and the cleaning conductor 1262 are electrically connected to the transformer mechanism 11 respectively, appropriate voltage or high voltage can be provided for different working conditions, which helps to improve the stability of ignition and the efficiency of the cleaning effect.

[0055] Optionally, in some embodiments, see Figure 2 and Figure 5 The second mounting portion 122 includes a first sub-mounting component 1221 and a second sub-mounting component 1222 . The first sub-mounting component 1221 and the second sub-mounting component 1222 are insulated from each other and are respectively located at two sides of the first mounting portion 121 .

[0056] The spark generating device 200 comprises a mounting shell 201, a central conductive member 202 and a side matching member 203. The central conductive member 202 comprises a conductive segment 2021 protruding from the outside of the mounting shell 201. The side matching member 203 comprises a matching segment 2031 protruding from the outside of the mounting shell 201. The conductive segment 2021 and the matching segment 2031 cooperate to generate high pressure to ignite the mixed gas. The carbon deposit cleaning mechanism 20 comprises a first cleaning component 21 and a second cleaning component 22, wherein: The first cleaning component 21 is located below the high voltage conducting mechanism 12 and is electrically connected to the first sub-mounting member 1221 ; the first cleaning component 21 extends to one side of the conductive segment 2021 to clean carbon deposits on the conductive segment 2021 .

[0057] The second cleaning component 22 is located below the high voltage conducting mechanism 12 and is electrically connected to the second sub-mount 1222 ; the second cleaning component 22 extends to one side of the mating section 2031 ; the first cleaning component 21 and the second cleaning component 22 are arranged opposite to each other; the second cleaning component 22 is used to clean the carbon deposits on the side mating component 203 .

[0058] Among them, the high-voltage transmission mechanism 12 is used to electrically connect the transformer mechanism 11 to the first mounting portion 121, the second sub-mounting component 1222 or the second sub-mounting component 1222 selectively; when the transformer mechanism 11 is electrically connected to the first sub-mounting component 1221, the high voltage generated by the transformer mechanism 11 is transmitted to the first cleaning component 21 through the first sub-mounting component 1221, so that the first cleaning component 21 cleans the carbon deposits on the conductive segment 2021; when the transformer mechanism 11 is electrically connected to the second sub-mounting component 1222, the high voltage generated by the transformer mechanism 11 is transmitted to the second cleaning component 22 through the second sub-mounting component 1222, so that the second cleaning component 22 cleans the carbon deposits on the mating segment 2031.

[0059] It can be understood that the first sub-mounting member 1221 is a structure capable of mounting the first cleaning member 21 and transmitting high voltage to the first cleaning member 21, for example, it can be a cylindrical mounting seat and a guide block disposed in the mounting seat, etc., but it is not limited thereto. The second sub-mounting member 1222 is a structure capable of mounting the second cleaning member 22 and transmitting high voltage to the second cleaning member 22, for example, it can be a cylindrical mounting seat and a guide block disposed in the mounting seat, etc., but it is not limited thereto. The mounting shell 201 is a shell structure capable of accommodating the central conductive member 202 and the side matching member 203. The central conductive member 202 is the central electrode of the spark plug, and the side matching member 203 is the side electrode of the spark plug, etc., but it is not limited thereto. The conductive segment 2021 is the ignition end in the central electrode and is located in the engine combustion chamber, and the matching segment 2031 is the protruding portion in the side electrode, and the portion that matches the conductive segment 2021 is also located in the engine combustion chamber. The first cleaning component 21 is a component that can use high voltage to clean the carbon deposits at the conductive segment 2021, and can be, for example, a structure with multiple discharge ends, but is not limited thereto. The second cleaning component 22 is a component that can use high voltage to clean the carbon deposits at the matching segment 2031, and can be, for example, a structure with multiple discharge ends, but is not limited thereto.

[0060] In this way, the first sub-mounting member 1221 and the second sub-mounting member 1222 are insulated from each other and are respectively located on both sides of the first mounting portion 121, which can prevent the voltage from being mistakenly transmitted to other components when cleaning carbon deposits, thereby improving safety during cleaning. When the automobile engine needs to work, the transformer mechanism 11 transmits the voltage to the first mounting portion 121 through the electrical connection portion 126, and the first mounting portion 121 transmits the voltage through the central electrode in the mounting shell 201. The voltage is matched with the matching segment 2031 of the side matching member 203 through the conductive segment 2021 of the central electrode. The conductive segment 2021 and the matching segment 2031 cooperate to generate high voltage to break through the matching segment 2031 to generate electric sparks and ignite the mixed gas. When it is necessary to clean the carbon deposits on the conductive segment 2021, the high voltage generated by the transformer mechanism 11 is transmitted to the first sub-mounting member 1221 of the second mounting portion 122 through the electrical connection portion 126. The first sub-mounting member 1221 transmits the high voltage to the first cleaning member 21. Then, the first cleaning member 21 extending to one side of the conductive segment 2021 is used to apply the high voltage to the conductive segment 2021 to clean the carbon deposits on the conductive segment 2021. When it is necessary to clean the carbon deposits on the mating segment 2031, the high voltage generated by the transformer mechanism 11 is transmitted to the first sub-mounting member 1221 of the second mounting portion 122 through the electrical connection portion 126. The first sub-mounting member 1221 transmits the high voltage to the first cleaning member 21. Then, the first cleaning member 21 extends to one side of the conductive segment 2021. The first cleaning member 21 applies the high voltage to the conductive segment 2021 to clean the carbon deposits on the conductive segment 2021. 6 is transmitted to the second sub-mounting member 1222 of the second mounting portion 122, and the second sub-mounting member 1222 transmits the high voltage to the second cleaning member 22, and then the second cleaning member 22 extending to the side of the matching segment 2031 is used to apply the high voltage to the matching segment 2031 to clean the carbon deposits on the matching segment 2031. The carbon deposits of the conductive segment 2021 and the matching segment 2031 can be cleaned separately. Since there is a special first cleaning member 21 for the conductive segment 2021 and the second cleaning member 22 for the matching segment 2031, the carbon deposits can be accurately processed. For example, the positions and degrees of carbon deposits formed in the conductive segment 2021 and the matching segment 2031 during the working process may be different. This targeted cleaning can effectively remove the carbon deposits according to the actual situation, so that the conductive segment 2021 and the matching segment 2031 have a good working state. When the high voltage is applied to the conductive segment 2021 and the matching segment 2031, the carbon deposits can be instantly impacted and reflected. Compared with traditional cleaning methods (such as chemical cleaning which may require longer soaking time and complicated operating procedures), this cleaning method can complete the removal of carbon deposits in a short time and reduce the time cost of engine maintenance.

[0061] Optionally, the electrical connection portion 126 includes an ignition conductor 1261 and a cleaning conductor 1262 , wherein the cleaning conductor 1262 includes a first conductor and a second conductor; the first conductor and the second conductor are sequentially spaced apart on both sides of the ignition conductor 1261 along the translation direction of the controllable conductive member 124 . When the second end of the controllable conductive part 124 is electrically connected to the first sub-mount 1221 and the first end of the controllable conductive part 124 is electrically connected to the first conductor, the first end of the controllable conductive part 124 is electrically connected to the second conductor; when the second end of the controllable conductive part 124 is electrically connected to the second sub-mount 1222 and the first end of the controllable conductive part 124 is electrically connected to the third conductor, the first end of the controllable conductive part 124 is electrically connected to the fourth conductor. Different cleaning paths can be achieved, and the electrical connection state can be flexibly adjusted as needed (for example, cleaning carbon deposits on the conductive segment 2021 or cleaning carbon deposits on the mating segment 2031). The flexible electrical connection method enhances the adaptability of the equipment to different cleaning tasks, effectively avoids the risk of short circuit between different functional circuits, and contributes to the stability and reliability of the electrical connection.

[0062] Optionally, in some embodiments, see Figure 2 and Figure 4 The second cleaning component 22 includes a main cleaning part 221 and an auxiliary cleaning part 222. One end of the main cleaning part 221 is electrically connected to the second sub-mounting member 1222. The auxiliary cleaning part 222 is connected to the other end of the main cleaning part 221; the auxiliary cleaning part 222 is arc-shaped, and at least a part is located at the bottom of the matching section 2031; the main cleaning part 221 is electrically connected to the second mounting part 122; the first cleaning component 21 is arranged opposite to the main cleaning part 221 and the auxiliary cleaning part 222.

[0063] It can be understood that the main cleaning part 221 is a structure capable of cleaning carbon deposits at least in part of the side electrode, for example, it can be composed of multiple discharge ends, etc., but not limited to this; the main cleaning part 221 is parallel to at least part of the side electrode. The auxiliary cleaning part 222 is a structure capable of cleaning carbon deposits at least in part of the side electrode, for example, it can be composed of multiple discharge ends, etc., but not limited to this; wherein the auxiliary cleaning part 222 is in an arc shape, and at least a part of it is located below the bottom of the matching section 2031, and the height of at least a part of the auxiliary cleaning part 222 located below the bottom of the matching section 2031 does not exceed 5mm (which can be determined according to the width and length of the side electrode, for example, it can be 4mm, 3mm or 1mm, etc.). The shape of the main cleaning part 221 and the auxiliary cleaning part 222 after being connected is the same as the shape of the matching section 2031 of the side matching piece 203, but the bottom of the auxiliary cleaning part 222 is located below the bottom of the matching section 2031.

[0064] With such arrangement, when cleaning the carbon deposits on the mating segment 2031 and the conductive segment 2021, the auxiliary cleaning portion 222 is arc-shaped, and at least a portion is located at the bottom of the mating segment 2031. The main cleaning portion 221 can be used to clean the carbon deposits on at least a portion of the mating segment 2031 (the mating segment 2031 may include a first portion and a second portion, the first portion is a portion without bending or other shapes, and may be straight, and the second portion is an arc-shaped portion; the main cleaning portion 221 cleans the first portion of the mating segment 2031, and the second portion is cleaned by the auxiliary cleaning portion 222). The auxiliary cleaning portion 222 is used to clean the carbon deposits on the remaining portion of the mating segment 2031, so as to completely clean the carbon deposits without cleaning dead corners. During the operation of the mating segment 2031, carbon deposits may form on various surfaces, including the bottom. For example, during the engine combustion process, impurities and incompletely burned substances produced by the combustion may be deposited at the bottom and sides of the mating section 2031. By cleaning part of the area with the main cleaning section 221 and cleaning the remaining areas such as the bottom with the auxiliary cleaning section 222, carbon deposits can be reduced and the cleaning effect can be effectively improved. Different areas of the mating section 2031 can be cleaned at the same time, and the carbon deposit cleaning work of the entire mating section 2031 can be completed in a shorter time.

[0065] Optionally, in some embodiments, see Figure 4 A plurality of first electrodes 211 are sequentially arranged at intervals on the first cleaning component 21 , and the first electrodes 211 protrude toward the conductive segment 2021 ; a plurality of second electrodes 223 are sequentially arranged at intervals on the second cleaning component 22 , and the second electrodes 223 protrude toward the matching segment 2031 .

[0066] It can be understood that the first cleaning component 21 is provided with a plurality of first electrodes 211 arranged in sequence at intervals, and the number of the first electrodes 211 may be 5, 7 or 8, etc., but is not limited thereto. The number of the first electrodes 211 may be specifically set according to the length of the ignition end of the center electrode of the existing spark plug. No matter how many are set, the ignition end of the center electrode needs to be covered (the ignition end of the center electrode can be covered by the length from the first first electrode 211 to the last first electrode 211 being greater than the length of the ignition end of the center electrode, but the length from the first first electrode 211 to the last first electrode 211 cannot exceed 2 mm of the length of the ignition end of the center electrode); the second electrode 223 is similar to the first electrode 211 and will not be repeated.

[0067] In this way, the arrangement of multiple first electrodes 211 and multiple second electrodes 223 enables multiple points to act simultaneously when cleaning carbon deposits, and high voltage impact can be performed from multiple positions. Compared with a single electrode, the multi-point design can cover a larger area and remove carbon deposits more effectively. For example, the distribution of carbon deposits on the conductive segment 2021 and the matching segment 2031 may be uneven, and multiple electrodes can make the carbon deposits at various positions be cleaned, and the time can be greatly shortened.

[0068] Optionally, in some embodiments, see Figure 4 A first discharge gap 2111 is provided between two adjacent first electrodes 211, and a second discharge gap 2231 is provided between two adjacent second electrodes 223. The widths of the first discharge gap 2111 and the second discharge gap 2231 are both 3-5 mm.

[0069] It can be understood that there is a first discharge gap 2111 between two adjacent first electrodes 211, and there are multiple first discharge gaps 2111. The multiple first discharge gaps 2111 can be different, but the width of the discharge gap should be within the range of 3-5mm. The first discharge gap 2111 and the second discharge gap 2231 are similar and will not be described in detail.

[0070] In this way, the width of the first discharge gap 2111 and the second discharge gap 2231 are both 3-5mm. The gap range of 3-5mm is moderate, which can not only generate a discharge spark of sufficient intensity, but also effectively cover the carbon deposit area. The spark intensity and discharge stability are conducive to the rapid decomposition and combustion of carbon deposits, improve the cleaning efficiency, prevent the discharge from being unstable or difficult to break through due to the gap being too large, and prevent the spark intensity from being insufficient due to the gap being too small. When the width of the first discharge gap 2111 and the second discharge gap 2231 is 3-5mm, stable spark discharge can be provided, which is conducive to the reliable conduct of the discharge process. The appropriate gap can make the spark generate sufficient high temperature and impact force, which is conducive to breaking up the carbon deposits and burning them off, and achieving a better cleaning effect.

[0071] Optionally, in some embodiments, see Figure 1 , Figure 2 and Figure 4 , the shapes of the plurality of first electrodes 211 and the plurality of second electrodes 223 are tooth-shaped.

[0072] It can be understood that the shape is tooth-shaped; the shape of the tooth-shaped electrode can change the distribution of the electric field. Since the radius of curvature of the tooth tip is small, according to the electric field theory, the electric field strength at the tooth tip will be relatively high. When voltage is applied to the electrode, the tooth tip can generate a stronger electric field, thereby more effectively ionizing the surrounding air and generating active substances such as plasma to clean carbon deposits.

[0073] In this way, the shapes of the multiple first electrodes 211 and the multiple second electrodes 223 are set to be tooth-shaped. The shape characteristics of the tooth-shaped electrodes increase the contact area between the conductive segment 2021 and the matching segment 2031 compared to electrodes of ordinary shapes; when the electrodes are energized to release high voltage to clean carbon deposits, they can directly contact the high voltage electric field on the electrode surface, thereby improving the cleaning effect; on the conductive segment 2021 and the matching segment 2031, the distribution of carbon deposits is often uneven, and block-shaped or striped carbon deposits may form. The tooth-shaped electrode can better cover and fit the irregular distribution of carbon deposits, and its teeth can correspond to the gaps of carbon deposits, so that carbon deposits in every corner can be cleaned, which can produce a stronger decomposition and removal effect on carbon deposits.

[0074] Optionally, in some embodiments, see Figure 1 , Figure 2 and Figure 4 The carbon deposit cleaning mechanism 20 also includes a first mounting member 23 and a second mounting member 24. The first mounting member 23 is plugged into and matched with the first sub-mounting member 1221, and the second mounting member 24 is plugged into and matched with the second sub-mounting member 1222; the first cleaning component 21 is arranged on the first mounting member 23, and the second cleaning component 22 is arranged on the second mounting member 24; the first mounting member 23 is used to be detachably arranged on the cylinder head, and the second mounting member 24 is used to be detachably arranged on the cylinder head.

[0075] It can be understood that the first mounting member 23 is a structure that can be plugged with the first sub-mounting member 1221 and conduct the high voltage to the first cleaning member 21, for example, it can be a cylindrical structure, etc., but not limited to this. The second mounting member 24 is a structure that can be plugged with the second sub-mounting member 1222 and conduct the high voltage to the second cleaning member 22, for example, it can be a cylindrical structure, etc., but not limited to this. Among them, the first mounting member 23 has an inner sleeve, the first cleaning member 21 has an outer sleeve, and the inner sleeve of the first mounting member 23 is plugged and connected with the outer sleeve of the first cleaning member 21. The inner sleeve can be cylindrical, and its outer surface has multiple circles of conductive rings, and the conductive rings can be made of metal material. The outer sleeve is a hollow cylinder, and its inner wall has a conductive brush or conductive sheet corresponding to the conductive ring of the inner sleeve; when plugging, the inner sleeve is inserted into the outer sleeve so that the conductive ring is in close contact with the conductive brush.

[0076] With such a configuration, the installation and removal process is simple and quick using a plug-in method. During installation, the connection can be completed by simply inserting the mounting component into the corresponding sub-mounting component. No complicated tools or cumbersome operating steps are required, and external electromagnetic interference will not affect the internal electrical conduction path. When cleaning the carbon deposits on the conductive segment 2021, the high voltage is transmitted to the first sub-mounting component 1221, the first mounting component 23 is plugged in with the first sub-mounting component 1221, and the high voltage is transmitted to the first cleaning component 21 through the first mounting component 23 to clean the carbon deposits on the conductive segment 2021; when cleaning the carbon deposits on the mating segment 2031, the high voltage is transmitted to the second sub-mounting component 1222, the second mounting component 24 is plugged in with the second sub-mounting component 1222, and the high voltage is transmitted to the second cleaning component 22 through the second mounting component 24 to clean the carbon deposits on the conductive segment 2021, so that the carbon deposit cleaning of the conductive segment 2021 and the mating segment 2031 have independent conduction. path to avoid cross-influence; when cleaning the carbon deposit on the mating segment 2031, the independent conduction path conducts the high voltage to the second cleaning component 22 through the second sub-mount 1222 and the second mounting member 24, avoiding mutual interference between the cleaning conductive segment 2021 and the mating segment 2031 during the cleaning process; compared with the absence of an independent conduction path, the absence of an independent conduction path will result in chaotic conduction of high voltage between the first cleaning component 21 and the second cleaning component 22, resulting in poor cleaning effect and even possible damage to the cleaning components or other engine components, thereby improving the safety of the cleaning process, isolating high voltage risks, and reducing damage to electronic components, so as to improve service life and work reliability.

[0077] Optionally, the first cleaning component 21 is insulatedly arranged on the first mounting member 23 by an insulating material, and the second cleaning component 22 is insulatedly arranged on the second mounting member 24 by an insulating material; the insulating material may be an insulating ceramic material with high temperature resistance, etc., but is not limited thereto. By insulating the first cleaning component 21 from the first mounting member 23, and the second cleaning component 22 from the second mounting member 24, it is possible to prevent the first cleaning component 21 from conducting high voltage to other parts of the vehicle after conducting with the first mounting member 23, and to prevent the conduction voltage from becoming smaller and smaller, which helps to improve the safety and voltage reliability when removing carbon deposits.

[0078] Optionally, the first hole and the second hole can be opened within the angle range of the side or periphery of the cylinder head; the first hole and the second hole are arranged opposite to each other, and the inner side walls of the first hole and the second hole both have hole threads, the outer side wall of the first mounting member 23 is provided with an external thread for tightening with the hole thread on the inner side wall of the first hole, and the outer side wall of the second mounting member 24 is provided with an external thread for tightening with the hole thread on the inner side wall of the second hole. For example, for an inline four-cylinder engine, the first hole and the second hole can be opened around the spark plug corresponding to each cylinder; wherein the center electrode of the spark plug is the same as the center conductive member 202 in the present application, the side electrode of the spark plug is the same as the side mating member 203 in the present application, the ignition point of the center electrode of the spark plug is the same as the conductive segment 2021 in the present application, and the ignition point of the side electrode of the spark plug is the same as the mating segment 2031 in the present application.

[0079] When the first mounting member 23 is installed in cooperation with the hole thread on the inner wall of the first hole, and the second mounting member 24 is installed in cooperation with the hole thread on the inner wall of the second hole, the hole thread can use fine thread, which has higher pitch accuracy and better connection sealing than coarse thread; for example, M8×1 (diameter 8mm, pitch 1mm) or M10×1.25 (diameter 10mm, pitch 1.25mm), which can provide a more stable connection and prevent the cleaning parts from loosening due to vibration and other reasons during the operation of the engine, which helps to improve the reliability of the threaded connection and avoid damage to the cylinder head.

[0080] The number of rotations of the first mounting member 23 in the first hole can be determined according to the specific size and installation position of the first cleaning member 21 and the spark generating device 200, so that after the first mounting member 23 rotates a preset number of times in the first hole, the first electrode 211 faces the conductive segment 2021. Similarly, the number of rotations of the second cleaning member 22 in the second hole can be determined according to the specific size and installation position of the second cleaning member 22 and the spark generating device 200, so that after the second cleaning member 22 rotates a preset number of times in the second hole, the second electrode 223 faces the side of the matching segment 2031 that is away from the conductive segment 2021.

[0081] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
