Description

Technical Field

[0001] The utility model relates to the technical field of side - electrode spark plugs, and specifically relates to a semi - surface multi - side - electrode spark plug. Background Technique

[0002] A spark plug is an important component of a gasoline engine ignition system. It can introduce high - voltage electricity into the combustion chamber and make it jump across the electrode gap to generate a spark, thereby igniting the combustible mixture in the cylinder. It mainly consists of a terminal nut, an insulator, a terminal screw, a center electrode, a side electrode, and a housing. The side electrode is welded to the housing.

[0003] For example, the patent document with the publication number CN 213878721 U discloses a perforated - electrode spark plug, including a spark - plug body, a center electrode, and a side electrode. An insulator is wrapped around the outside of the center electrode. The center electrode is installed in the middle section of the spark - plug body, and one end of the center electrode protrudes relatively from the spark - plug body. The side electrode is installed at the edge of the end of the spark - plug body. The side electrode is provided with a through - hole, and there is a gap between the through - hole and the center electrode. The above - mentioned perforated - electrode spark plug improves the ignition effect by improving the electrode structure of the spark plug, improves the combustion efficiency of gasoline in the engine cylinder, effectively reduces fuel consumption, and can avoid engine carbon deposition caused by insufficient gasoline combustion efficiency, ensuring that the spark plug is not easily contaminated, thereby effectively improving the service life of the spark - plug body.

[0004] However, during the actual use of this structure, due to its own structural limitations, it can often only perform the energized ignition operation between a set of positive and negative electrodes, resulting in a relatively high risk of ignition failure for the entire device. It is impossible to perform more accurate and stable electric - ignition operations. At the same time, the device cannot perform the operation of limiting and fixing the installation position, cannot ensure the stability of the overall spark plug, and cannot meet the daily use requirements. It can often only perform one set, so it is urgent to design a semi - surface multi - side - electrode spark plug to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a semi - surface multi - side - electrode spark plug to solve the problems in the above - mentioned background technique. During the actual use of the existing structure, due to its own structural limitations, it can often only perform the energized ignition operation between a set of positive and negative electrodes, resulting in a relatively high risk of ignition failure for the entire device. It is impossible to perform more accurate and stable electric - ignition operations. At the same time, the device cannot perform the operation of limiting and fixing the installation position, cannot ensure the stability of the overall spark plug, and cannot meet the daily use requirements.

[0006] To achieve the above object, the utility model provides the following technical solutions: A semi-surface multi-side electrode spark plug, including a threaded socket, a center electrode is arranged at the center of the top of the threaded socket, an arc-shaped side cover is fixedly connected to one side of the top of the threaded socket, an arc-shaped top cover is fixedly connected to the top end of the arc-shaped side cover, an installation arc seat is fixedly connected to the top end inner wall of the arc-shaped side cover, and an arc-shaped multi-side electrode is arranged at the bottom of the installation arc seat;

[0007] A nut, the bottom end of the threaded socket is fixedly connected with a nut, and an energizing socket is arranged at the bottom end of the nut.

[0008] Preferably, a sealing ring is sleeved on the surface of the nut, and a threaded ring is fixedly connected to the inner wall of the sealing ring.

[0009] Preferably, a limit connection seat is fixedly connected to the surface of the nut, and a positioning rubber ring is arranged on the side of the limit connection seat.

[0010] Preferably, a guiding hole groove is opened at the top end of the arc-shaped top cover, and a guiding cone cover is arranged between the arc-shaped top cover and the installation arc seat.

[0011] Preferably, the guiding hole groove and the guiding cone cover are adapted to each other.

[0012] Preferably, a sealing gasket is arranged on the surface of the installation arc seat, and a positioning arc bar is fixedly connected to the back of the surface of the installation arc seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] For this semi-surface multi-side electrode spark plug, through the arranged threaded socket, center electrode, arc-shaped side cover, arc-shaped top cover, installation arc seat, arc-shaped multi-side electrode, nut and energizing socket, the device can perform more accurate and stable semi-surface multi-side electrode ignition operations. In the actual use process, the staff first fixedly installs the whole device to be used through the threaded socket, and screws and installs one end of the center electrode, the arc-shaped side cover and the arc-shaped top cover at the electric ignition position of the engine. Usually, power is supplied internally from the energizing socket, and the current is respectively led to the center electrode at the top of the threaded socket and the arc-shaped multi-side electrode at the bottom of the installation arc seat inside the arc-shaped side cover. At this time, through the multi-electrode design of the arc-shaped multi-side electrode, multiple currents can conduct electricity to the center electrode simultaneously, so that the current at the center electrode can conduct continuous and accurate electric ignition operations more stably. The covering and protection of the arc-shaped side cover and the arc-shaped top cover also ensure the stable guiding of the current, reflecting the practicability of the device design.

[0015] The semi-surface multi-side electrode spark plug further improves the overall use effect of the device through the provided sealing ring, threaded ring, limit socket, positioning rubber ring, guiding hole groove, guiding cone cover, sealing gasket and positioning arc strip. During daily use, the staff can first screw and install the sealing ring on the side of the threaded socket through the threaded ring on the inner wall, and then sleeve the sealing ring on the limit socket on the surface of the nut and install it with sealing and positioning through the positioning rubber ring. When the threaded socket is installed later, the sealing ring can be used to properly seal and reinforce the interface. At the same time, the guiding cone cover can be placed between the installation arc seats of the arc-shaped top cover and the arc-shaped side cover. Under the limit fixation of the sealing gasket and the positioning arc strip, the guiding cone cover can guide the electric ignition fuel to the top of the arc-shaped top cover and the guiding hole groove, ensuring the efficient progress of each electric ignition and reflecting the comprehensiveness of the device design.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0023] A semi-surface multi-side electrode spark plug includes a threaded socket 1. A center electrode 2 is arranged at the center of the top of the threaded socket 1. One side of the top of the threaded socket 1 is fixedly connected with an arc-shaped side cover 3. The top end of the arc-shaped side cover 3 is fixedly connected with an arc-shaped top cover 4. The inner wall top end of the arc-shaped side cover 3 is fixedly connected with a mounting arc seat 5. An arc-shaped multi-side electrode 6 is arranged at the bottom of the mounting arc seat 5. A guiding hole groove 13 is opened at the top end of the arc-shaped top cover 4. A guiding cone cover 14 is arranged between the arc-shaped top cover 4 and the mounting arc seat 5. The guiding hole groove 13 and the guiding cone cover 14 are adapted to each other. A sealing gasket 15 is arranged on the surface of the mounting arc seat 5. A positioning arc strip 16 is fixedly connected to the back of the surface of the mounting arc seat 5. The current is respectively led to the center electrode 2 at the top of the threaded socket 1 and the arc-shaped multi-side electrode 6 at the bottom of the mounting arc seat 5 inside the arc-shaped side cover 3. At this time, through the multi-electrode design of the arc-shaped multi-side electrode 6, multiple strands of current can simultaneously conduct electricity to the center electrode 2, so that the current at the center electrode 2 can perform a continuous and accurate electric sparking operation more stably.

[0024] A nut 7 is fixedly connected to the bottom end of the threaded socket 1. An energizing socket 8 is arranged at the bottom end of the nut 7. A sealing ring 9 is sleeved on the surface of the nut 7. A threaded ring 10 is fixedly connected to the inner wall of the sealing ring 9. A limiting connection seat 11 is fixedly connected to the surface of the nut 7. A positioning rubber ring 12 is arranged on the side of the limiting connection seat 11. The sealing ring 9 is screwed and installed with the side of the threaded socket 1 through the threaded ring 10 on the inner wall. Then the sealing ring 9 is sleeved at the limiting connection seat 11 on the surface of the nut 7 and is sealed and positioned through the positioning rubber ring 12. After that, when the threaded socket 1 is installed, the sealing ring 9 can be used to properly seal and reinforce the interface.

[0025] Working principle: When in use, the operator first fixes and installs the entire device to be used through the threaded socket 1, and screws and installs one end of the central electrode 2, the arc-shaped side cover 3 and the arc-shaped top cover 4 at the electric ignition position of the engine. Usually, power is supplied internally from the power-on socket 8, and the current is respectively led to the central electrode 2 at the top of the threaded socket 1 and the arc-shaped multi-side electrode 6 at the bottom of the arc seat 5 installed inside the arc-shaped side cover 3. At this time, through its multi-electrode design, the arc-shaped multi-side electrode 6 can conduct electricity to the central electrode 2 simultaneously with multiple currents, so that the current at the central electrode 2 can perform continuous and accurate electric sparking operations more stably. The cover protection of the arc-shaped side cover 3 and the arc-shaped top cover 4 also ensures the stable guiding of the current. During daily use, the operator can first screw and install the sealing ring 9 on the side of the threaded socket 1 through the threaded ring 10 on the inner wall, and then sleeve the sealing ring 9 on the limit socket 11 on the surface of the nut 7, and perform sealing and positioning installation through the positioning rubber ring 12.

At the same time, a guiding cone cover 14 can be placed between the installation arc seats 5 of the arc-shaped top cover 4 and the arc-shaped side cover 3. Under the limit fixation of the sealing gasket 15 and the positioning arc strip 16, the guiding cone cover 14 can guide the electric sparking fuel to the top of the arc-shaped top cover 4 and the guiding hole groove 13, ensuring the efficient progress of each electric sparking operation. The above is the entire working principle of the present utility model.
