Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spark plugs, in particular to a porous automobile spark plug. Background Art
[0002] A spark plug is a component in a gasoline engine's ignition system that introduces high-voltage current into the cylinder, generating an electric spark to ignite the combustible mixture. It primarily consists of a wire nut, an insulator, a wire screw, a center electrode, a side electrode, and a housing. A specific gap separates the center electrode and the side electrode. This gap allows an arc to form between the center and side electrodes when pulsed power is applied, generating an electric spark. This ensures that the desired spark is generated within a specific time interval, leading to automatic ignition.
[0003] In order to facilitate the contact between the fuel gas and the center electrode and the discharge stage, most spark plugs do not have a protective structure on the outside of the center electrode and the discharge stage, resulting in the center electrode and the discharge stage being exposed to the combustion gas for a long time, which affects the service life of the spark plug. Therefore, a porous automotive spark plug is proposed to solve the above problem. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides a porous automobile spark plug, which has the advantages of protecting the outside of the center electrode and the discharge stage. It solves the problem that most spark plugs do not have a protective structure on the outside of the center electrode and the discharge stage in order to facilitate the contact between the fuel gas and the center electrode and the discharge stage, resulting in the center electrode and the discharge stage being exposed to the combustion gas for a long time, which affects the service life of the spark plug.
[0005] To achieve the above object, the present invention provides the following technical solution: a porous automobile spark plug, comprising a spark plug body, characterized in that a bolt is provided on the outside of the spark plug body, an insulator is provided at the bottom of the bolt, a grounding nut is provided at the bottom of the insulator, and a protective structure is provided on the top of the spark plug body;
[0006] The protective structure includes a first electrode, a fixed body, a central column, a second electrode, a spark hole, a protective cover and a vent. The first electrode is fixedly installed on the top of the spark plug body, the fixed body is fixedly installed on the top of the spark plug body, the central column is fixedly installed on the outside of the fixed body, the second electrode is fixedly installed on the bottom of the central column, the spark hole is opened on the outside of the fixed body, the protective cover is movably installed on the outside of the spark plug body, and the top of the protective cover is provided with a vent.
[0007] Furthermore, a spring is fixedly installed inside the protective cover, a movable plate is fixedly installed outside the spring, a clamping block is fixedly installed outside the movable plate, and a limiting plate is fixedly installed outside the spark plug body.
[0008] Furthermore, the first electrode is close to the second electrode, and a plurality of spark holes are provided on the exterior of the fixed body.
[0009] Furthermore, the protective cover is fitted with the limiting plate, and a slot is provided on the outside of the limiting plate.
[0010] Furthermore, the spring and the movable plate are both located inside the protective cover, and the clamping block passes through the protective cover and extends to the outside of the protective cover.
[0011] Furthermore, the card block is engaged with the card slot, the vent hole is located at the top of the protective cover, and there are two card blocks, which are respectively located on the left and right sides of the protective cover.
[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0013] In this porous automobile spark plug, when the first electrode and the second electrode are effectively discharging a fire, the gas enters the interior of the protective cover through the vent hole on the top of the protective cover, so that the gas is fully burned during the discharge. The spark holes opened on the outside of the fixed body increase the contact area between the spark and the gas, which can better ignite the gas and achieve a better ignition effect. When the protective cover needs to be cleaned, the card block is pressed to squeeze the spring through the movable plate, causing the card block to retract into the interior of the protective cover. At the same time, the protective cover is pulled upward to remove the protective cover from the spark plug body and clean it. While protecting the spark plug body, the gas can also be smoothly introduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-3 A porous automobile spark plug in this embodiment includes a spark plug body 1, a bolt 2 is provided on the outside of the spark plug body 1, an insulator 3 is provided at the bottom of the bolt 2, a grounding nut 4 is provided at the bottom of the insulator 3, and a protective structure 5 is provided on the top of the spark plug body 1.
[0020] The protective structure 5 includes a first electrode 501, a fixed body 502, a central column 503, a second electrode 504, a spark hole 505, a protective cover 506, a vent 507, a spring 6, a movable plate 7, a block 8 and a limit plate 9. The first electrode 501 is fixedly installed on the top of the spark plug body 1, the fixed body 502 is fixedly installed on the top of the spark plug body 1, the central column 503 is fixedly installed on the outside of the fixed body 502, the second electrode 504 is fixedly installed on the bottom of the central column 503, the spark hole 505 is opened on the outside of the fixed body 502, the protective cover 506 is movably installed on the outside of the spark plug body 1, and the top of the protective cover 506 is provided with a vent 507.
[0021] exist Figure 2 In the embodiment, the fixed body 502 is close to the top of the protective cover 506 , and the spark hole 505 is also close to the vent hole 507 . When the gas enters the protective cover 506 , it can quickly contact the first electrode 501 and the second electrode 504 .
[0022] exist Figure 3 In the embodiment, the limiting plate 9 supports the protective cover 506 and fixes the position of the protective cover 506 to prevent the protective cover 506 from falling off from the spark plug body 1 when the spark plug body 1 is in use.
[0023] exist Figure 3 In the embodiment, the bottom of the card block 8 is in an inclined state. When the protective cover 506 is installed, it is only necessary to press the protective cover 506 downwards. The card block 8 will retract due to the squeezing of the limit plate 9 until it reaches the card slot. The card block 8 rebounds to complete the card connection.
[0024] exist Figure 2 In the embodiment, the spark holes 505 outside the fixed body 502 are respectively located around the second electrode 504 and around the first electrode 501. The spark holes 505 are distributed in a circular state, thereby increasing the gas contact area.
[0025] In summary, when the first electrode 501 and the second electrode 504 are effectively discharged, the gas enters the protective cover 506 through the vent hole 507 on the top of the protective cover 506, so that the gas is fully burned under the condition of discharge. The spark hole 505 opened on the outside of the fixed body 502 increases the contact area between the spark and the gas, which can better ignite the gas and achieve a better ignition effect. When the protective cover 506 needs to be cleaned, the block 8 can be pressed to squeeze the spring 6 through the movable plate 7. The protective cover 506 can be removed from the outside of the spark plug body 1 by pulling the protective cover 506 upwards. The protective cover 506 can be cleaned, and the spark plug body 1 can be protected while the gas can enter smoothly. This solves the problem that most spark plugs do not have a protective structure 5 on the outside of the center electrode and the discharge stage in order to facilitate the contact between the gas and the center electrode and the discharge stage, resulting in the center electrode and the discharge stage being exposed to the combustion gas for a long time, thereby affecting the service life of the spark plug.
