Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of intake valve carbon deposit thickness early warning, and specifically relates to a device for early warning of excessive carbon deposit thickness on the back surface of an intake valve of a vehicle engine. BACKGROUND

[0002] During normal operation of the engine, gasoline and normal engine oil entering the combustion chamber cannot be completely combusted under insufficient oxygen supply, and oil fume and lubricating oil burnt particles are generated, which are further oxidized into gum. Under the repeated action of high temperature, the gum is further changed into asphalt, resin and carbon, thereby forming carbon deposits.

[0003] In the prior art, carbon deposits are easily formed on the back surface of the intake valve after long-term operation of the engine. Compared with carbon deposits formed on the piston, the inner surface of the intake pipe and the throttle body, the carbon deposit thickness formed on the back surface of the intake valve gradually decreases when the carbon deposit thickness increases day by day, which causes the intake valve to not completely close the intake port of the combustion chamber, thereby causing some unburnt fuel to continuously evaporate and oxidize, increasing the carbon deposits in the engine, and causing the engine to not work normally, thereby increasing the cost of vehicle maintenance. In view of the above problems, a device for early warning of excessive carbon deposit thickness on the back surface of an intake valve of a vehicle engine is designed. SUMMARY

[0004] To solve the problems in the background art, the application provides a device for early warning of excessive carbon deposit thickness on the back surface of an intake valve of a vehicle engine. The device has the advantages of early warning of excessive carbon deposit thickness on the back surface of the intake valve and small false alarm probability, and is achieved by the structures of the contact ring, the second connecting plate, the first connecting plate and the connecting ring. A gap is left between the contact ring and the intake valve. When the carbon deposit thickness on the back surface of the intake valve exceeds the dangerous height, the carbon deposit on the back surface of the intake valve drives the contact ring to move upward during upward movement of the intake valve, thereby achieving the advantages of early warning of excessive carbon deposit thickness on the back surface of the intake valve and small false alarm probability.

[0006] In the above technical scheme, preferably, the upper end of the connecting body is fixedly connected with the cylinder body, the connecting body is located in the intake pipe, the cylinder body is provided with a connecting hole near the outer side of the upper end of the connecting body, and the wire tube is fixedly sleeved in the connecting hole.

[0007] In the above technical scheme, preferably, the first connecting piece, the second connecting piece and the connecting ring are made of copper material, the first connecting piece and the second connecting piece are electrically connected with the display control end through the wire tube, and the first connecting piece and the second connecting piece do not contact the wall of the inner cavity of the sliding groove.

[0008] In the above technical scheme, preferably, the inner cavity of the display control end is provided with an alarm circuit, and the first connecting piece and the second connecting piece are two poles of a break in the alarm circuit.

[0009] In the above technical scheme, preferably, a gap is left between the bottom surface of the contact ring and the back surface of the intake valve and they are parallel to each other, the contact ring is trumpet-shaped as a whole, and a gap is left between the contact ring and the inner side wall of the intake pipe.

[0010] In the above technical scheme, preferably, the sealing ring is fixedly connected with the connecting body, the first magnetic ring is movably sleeved in the inner cavity of the sliding groove, four first limiting grooves are uniformly formed in the upper and lower ends of the second magnetic ring in a ring shape, and four second limiting grooves are uniformly formed in the upper and lower ends of the sealing ring in a ring shape.

[0011] In the above technical scheme, preferably, the four first limiting grooves and the four second limiting grooves are corresponding in position and matched with the four push pieces, and the four push pieces are movably sleeved in the four first limiting grooves and the four second limiting grooves respectively.

[0012] In the technical solution, preferably, the four transmission columns and the second insulating ring are movably sleeved in the inner cavity of the sliding groove, the connecting ring is not in contact with the inner cavity of the sliding groove, and a gap is left between the connecting ring and the first connecting piece and the second connecting piece.

[0016] The contact ring, the second connecting piece, the first connecting piece, the connecting ring and the like are used to achieve the purpose of early warning of excessive carbon thickness of the intake valve back area. A gap is left between the contact ring and the intake valve. When the bottom surface of the contact ring and the carbon thickness of the intake valve back area exceed the dangerous height, the carbon on the intake valve back area drives the contact ring to move upward during the upward movement of the intake valve, thereby driving the first magnetic ring to move upward, and driving the transmission column to move upward, and driving the second insulating ring and the connecting ring to move upward, so that the connecting ring is in contact with the first connecting piece and the second connecting piece, thereby making the first connecting piece and the second connecting piece connected, making the alarm circuit in the display control end connected, prompting the driver, and thereby achieving early warning of excessive carbon thickness of the intake valve back area.

[0017] The contact ring, the air inlet pipe and the combustion chamber are used to achieve the purpose of small false alarm probability. Through the design of the gas filter holes on the surface of the contact ring and the design of the magnetic material of the air inlet pipe and the combustion chamber, the impact force of the gas on the contact ring caused by the upward movement of the intake valve from the combustion chamber is reduced. When the gas impacts the surface of the contact ring to form an upward thrust, the weak magnetic adsorption of the air inlet pipe and the combustion chamber effectively prevents the air from driving the contact ring to move upward, avoids the possibility of false triggering of the alarm circuit by the intake valve driving the air, and thereby achieves small false alarm probability.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0027] As Figures 1 to 7 shown, the application provides a device for early warning of excessive carbon thickness of the back area of the intake valve of the engine of a vehicle, which comprises a cylinder 5 and an intake valve 4. The intake valve 4 is movably connected with the cylinder 5. The upper end of the intake valve 4 is provided with an intake pipe 7. The lower end of the intake valve 4 is provided with a combustion chamber 8. The outer side of the intake valve 4 movably sleeves a connector 1. The lower end of the connector 1 is provided with a sliding groove 20. The top surface of the inner cavity of the sliding groove 20 is fixedly connected with a first insulating ring 12. The front end of the lower end of the first insulating ring 12 is fixedly connected with a first connecting piece 13. The rear end of the lower end of the first insulating ring 12 is fixedly connected with a second connecting piece 21. The lower end of the inner cavity of the sliding groove 20 is fixedly connected with a sealing ring 19. The upper end of the sealing ring 19 is fixedly connected with a second magnetic ring 18. The upper end of the second magnetic ring 18 is magnetically attracted with a first magnetic ring 17. The lower end of the first magnetic ring 17 is uniformly fixedly connected with four push pieces 2 in a ring shape. The upper end of the first magnetic ring 17 is uniformly fixedly connected with four transmission columns 16 in a ring shape. The upper end of the four transmission columns 16 is fixedly connected with a second insulating ring 15. The upper end of the second insulating ring 15 is fixedly connected with a connecting ring 14. The lower end of the four push pieces 2 is fixedly connected with a contact ring 3. The outer side of the upper end of the connector 1 is fixedly connected with a wire tube 6. The side of the wire tube 6 away from the connector 1 is fixedly connected with a display control end 11.

[0028] As Figure 1, Figure 3 , Figure 5 and Figure 6 As shown, the upper end of the connector 1 is fixedly connected to the cylinder 5. The connector 1 is located inside the intake pipe 7. The cylinder 5 has a connection hole 9 on the outer side near the upper end of the connector 1. The wire tube 6 is fixedly sleeved in the connection hole 9. The first connecting piece 13, the second connecting piece 21 and the connecting ring 14 are made of copper. The first connecting piece 13 and the second connecting piece 21 are electrically connected to the display control terminal 11 through the wire tube 6. The first connecting piece 13 and the second connecting piece 21 do not contact the inner wall of the sliding groove 20. The inner cavity of the display control terminal 11 is equipped with an alarm circuit. The first connecting piece 13 and the second connecting piece 21 are the two extremes of the alarm circuit interruption. When the first connecting piece 13 and the second connecting piece 21 are connected, the interrupted alarm circuit is connected. When the alarm circuit is connected, it prompts the driver that the carbon thickness on the back of the intake valve has reached the warning height.

[0029] like Figure 1 and Figure 3 As shown, there is a gap between the bottom surface of the contact ring 3 and the back surface of the intake valve 4, and they are parallel to each other. The contact ring 3 is generally funnel-shaped, and there is a gap between the contact ring 3 and the inner wall of the intake pipe 7. Through the gap between the contact ring 3 and the intake valve 4 and the gap between the contact ring 3 and the inner wall of the intake pipe 7, when there is carbon buildup on the back surface of the intake valve 4 and the surface of the contact ring 3, as long as it does not exceed the dangerous height, the intake valve 4 will not drive the contact ring 3 to move when it is reciprocating, and thus will not trigger the internal structure of the connecting body 1.

[0030] like Figure 5 and Figure 7 As shown, the sealing ring 19 is fixedly connected to the connecting body 1. The first magnetic ring 17 is movably sleeved in the inner cavity of the sliding groove 20. The upper and lower ends of the second magnetic ring 18 are evenly provided with four first limiting grooves 1801. The upper and lower ends of the sealing ring 19 are evenly provided with four second limiting grooves 1901. The four first limiting grooves 1801 and the four second limiting grooves 1901 are correspondingly positioned and adapted to the four push plates 2. The four push plates 2 are movably sleeved in the four first limiting grooves 1801 and the four second limiting grooves 1901, respectively. The sealing ring 19 seals and protects the inner cavity of the sliding groove 20 to prevent unburned fuel vaporization from entering the sliding groove 20, causing carbon buildup inside the sliding groove 20, and affecting the normal operation of the internal structure of the sliding groove 20.

[0031] like Figures 4 to 7As shown, the four transmission columns 16 and the second insulating ring 15 are movably sleeved in the inner cavity of the sliding groove 20, the connecting ring 14 does not contact the inner cavity of the sliding groove 20, and a gap is left between the connecting ring 14 and the first connecting piece 13 and the second connecting piece 21; when the carbon on the back surface of the intake valve 4 is too thick, the upward and downward reciprocating movement of the intake valve 4 will push the contact ring 3 to move upward, the contact ring 3 will push the first magnetic ring 17 to move upward, the first magnetic ring 17 will drive the four transmission columns 16 to move upward, the four transmission columns 16 will push the second insulating ring 15 to move upward, thereby driving the connecting ring 14 to move upward, so that the connecting ring 14 contacts the first connecting piece 13 and the second connecting piece 21, thereby enabling the alarm circuit in the display control end 11 to be connected.

[0032] As shown in the figure, Figures 1 to 4 The intake pipe 7 and the combustion chamber 8 are made of weak magnetic materials, the outer surface of the contact ring 3 is provided with gas filter holes, the outer side of the connecting body 1 is uniformly provided with four air grooves 10, and the four transmission columns 16 and the four air grooves 10 are staggered; through the design of the gas filter holes on the surface of the contact ring 3, the area of the contact ring 3 blocking the air entering and exiting the combustion chamber 8 is reduced, and at the same time, the air grooves 10 are matched to enable the air to pass through the connecting body 1 to enter and exit the combustion chamber 8, thereby reducing the influence of the size of the device on the amount of air entering and exiting the combustion chamber 8, and through the design of the gas filter holes on the surface of the contact ring 3 and the design of the magnetic materials of the intake pipe 7 and the combustion chamber 8, the impact force of the gas driven by the upward movement of the intake valve 4 from the combustion chamber 8 on the contact ring 3 is reduced, and through the design of the magnetic materials of the intake pipe 7 and the combustion chamber 8, when the gas impact on the surface of the contact ring 3 forms an upward thrust, the weak magnetic adsorption of the intake pipe 7 and the combustion chamber 8 effectively prevents the air from driving the contact ring 3 to move upward, thereby avoiding the possibility of the intake valve 4 driving the air to trigger the alarm circuit by mistake

[0033] The working principle and use process of the present application are as follows:

[0034] The connecting body 1 is sleeved on the outer side of the intake valve 4 and fixedly connected with the cylinder body 5, so that the connecting body 1 and the intake valve 4 move in the same direction; when the carbon on the bottom surface of the contact ring 3 and the back surface of the intake valve 4 forms and gradually thickens, when the carbon reaches a thickness that is easy to cause incomplete closing of the intake valve 4, and the intake valve 4 moves upward, the carbon on the opposite side of the intake valve 4 will push the contact ring 3 to move upward, and at the same time, will drive the push piece 2 to move upward, the push piece 2 will push the first magnetic ring 17 to separate from the second magnetic ring 18, and make the first magnetic ring 17 move upward, the first magnetic ring 17 drives the four transmission columns 16 to move upward, the transmission columns 16 push the second insulating ring 15 and the connecting ring 14 to move upward, the connecting ring 14 moves upward and contacts the first connecting piece 13 and the second connecting piece 21, so that the second connecting piece 21 and the first connecting piece 13 are connected, so that the alarm circuit in the display control end 11 works, prompting the driver that the carbon thickness on the intake valve of the vehicle engine has reached a dangerous height;

[0035] The four air vent grooves 10 and the air filter holes on the surface of the contact ring 3 effectively reduce the resistance of the device to the flowing gas, and reduce the influence on the amount of gas in and out of the combustion chamber 8 per unit time. At the same time, when the intake valve 4 moves upward, the gas in the combustion chamber 8 will be driven upward, and an upward impact force will be formed on the contact ring 3. The air filter holes on the surface of the contact ring 3 reduce the upward force of the impact force on the contact ring 3. At the same time, the first magnetic ring 17 and the second magnetic ring 18 are weakly magnetically attracted to each other, avoiding the impact force formed by the air driven by the intake valve 4 causing the first magnetic ring 17 to push the first connecting piece 13 to move upward, causing the alarm circuit to be connected and false alarms to occur.
