Description

Technical Field

[0001] This application relates to the technical field of air filters, and particularly to an air filter applicable to a new energy internal combustion engine. Background Art

[0002] As an engine that generates power by burning fuel, the internal combustion engine is one of the most widely used engines in the modern industrial and transportation fields. With the progress of technology, new energy internal combustion engines can achieve low-carbon zero-carbon emissions, low noise, and high-efficiency operation, effectively solving problems such as high fuel consumption, high emissions, and high noise existing in old internal combustion engines, and thus gradually replacing old internal combustion engines, becoming a new development trend of internal combustion engines.

[0003] In recent years, ammonia-hydrogen internal combustion engines, as a type of new energy internal combustion engines, use a mixture of ammonia and hydrogen as fuel, combining the advantages of ammonia and hydrogen fuels to achieve the goal of zero carbon emissions, thus contributing to addressing the challenges of global climate change and environmental protection. And the air filter is an essential component of the intake system of ammonia-hydrogen internal combustion engines. Its main function is to filter out dust and impurities in the air, ensure the cleanliness of the gas entering the internal combustion engine, reduce the wear of various moving parts related to the internal combustion engine, improve the reliability and durability of the internal combustion engine, thereby extending the service life of the internal combustion engine and reducing the maintenance frequency.

[0004] The existing air filter mainly consists of a housing and a filter element. The filter element is cylindrical. When in use, air enters from the side of the housing through the intake pipe, and then passes through the filter element for filtration, separating or attaching the dust in the air from the filter element, and the filtered air is discharged from the outlet pipe connected to the inside of the filter element, thereby improving the cleanliness of the air entering the ammonia-hydrogen internal combustion engine and avoiding the occurrence of the "cylinder scoring" phenomenon, and extending the service life of the internal combustion engine.

[0005] However, there are still some defects in the existing air filter during use: Since the air enters from the side wall of the housing, one side of the filter element always bears the instantaneous impact force when the air flow enters, which not only causes this part of the filter element to be more easily damaged compared to other parts, affecting the service life of the filter element, but also makes this part of the filter element more likely to accumulate dust and impurities compared to other parts, affecting the filtering effect of the filter element. Summary of the Invention

[0006] This application proposes an air filter applicable to a new energy internal combustion engine, which has the advantages of fully protecting and timely cleaning the filter element by using a guiding mechanism, and is used to solve the problems that the side wall of the filter element opposite to the intake pipe is easily damaged and easily accumulates dust and impurities.

[0033] The beneficial effects of the present invention are as follows:

[0034] An air filter applicable to a new energy internal combustion engine provided by the present application movably arranges a guiding mechanism between a filtering mechanism and an air inlet pipe. The guiding mechanism is composed of a guide plate, a guide rail, and a cleaning assembly. When the air inlet pipe intakes air, the guide plate effectively guides the airflow to move along the circumferential direction of the main housing, realizing the protection of the side wall of the filter element facing the air inlet pipe, so that the side wall of the filter element does not bear the instantaneous impact force when the airflow enters, thereby preventing the filter element from being damaged and prolonging the service life of the filter element. At the same time, the guide plate is pushed by the airflow and moves towards the filter element, so that the cleaning assembly inserts and cleans the filter element, realizing the full cleaning of the dust and impurities attached to the side wall of the filter element, improving the filtering effect and efficiency of the filter element on air, and thereby preventing the dust and impurities from continuously accumulating on the outer wall of the filter element and causing the filtering effect to decline.

[0035] By providing a guide groove on the outer sidewall of the guide plate and a spiral groove on the guide groove, the air flow blocked by the guide plate can be effectively guided, causing the air flow to rotate by itself when moving circumferentially along the main housing. As a result, some dust with a large mass fails to pass through the filter element with the air due to inertia and adheres to the inner wall of the main housing, effectively reducing the filtration pressure on the filter element. At the same time, since the cleaning component is movably clamped in the guide groove of the guide plate and can swing up and down, when the air flow rotates along the guide groove of the guide plate, the air flow can push the cleaning component to swing up and down, achieving full cleaning of the outer wall of the filter element, thereby further improving the air filtration effect and further extending the service life of the filter element.

[0036] By providing a filtering mechanism, the filter element is arranged between a fixed plate and a movable plate, and the filter element is fixedly supported by an outer fixing rod and an inner fixing rod, keeping the layers of the filter element separated from each other, improving the stability of the position and posture of the filter element. This can not only avoid the problem of reduced filtration effect caused by the bonding of the filter element during long-term use, but also facilitate the disassembly and replacement of the filter element, and more importantly, prepare for the subsequent self-rotation of the filter element.

[0037] By connecting a movable push plate to the inner sidewall of the guide plate and movably arranging a toothed block in the movable push plate, when the guide plate moves towards the filter element, the toothed block on the movable push plate meshes with the movable column, thereby driving the entire filtering mechanism to rotate, realizing the change of the position of the sidewall of the filter element, so that the cleaning component on the guide plate can clean all positions of the filter element, further improving the filtration efficiency of the filter element. At the same time, by providing a fixed push plate at the bottom end of the upper sealing cover and movably arranging a toothed block in the fixed push plate, when the guide plate moves away from the filter element, the toothed block on the fixed push plate meshes with the movable column, making the entire filtering mechanism not rotate, effectively ensuring that the filtering mechanism rotates only in one direction and further ensuring that all parts of the filter element can be fully cleaned.

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] Embodiment 1, an air filter applicable to a new energy internal combustion engine, includes a main housing 11, as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 . The top end of the main housing 11 is fixedly clamped with an upper sealing cover 12, and the bottom end of the main housing 11 is fixedly clamped with a lower sealing cover 13. Using the upper sealing cover 12 and the lower sealing cover 13 to seal both ends of the main housing 11 can provide conditions for the stable installation of the filtering mechanism 2 in the main housing 11. In addition, it can be detached from the main housing 11 through the upper sealing cover 12 or the lower sealing cover 13 to realize the replacement of the filtering mechanism 2. One side wall of the main housing 11 is fixedly communicated with an air inlet pipe 14, and the middle of the lower sealing cover 13 is fixedly communicated with an air outlet pipe 15. The air inlet pipe 14 can be used to make air enter the main housing 11, and the air outlet pipe 15 can be used to make air discharge from the main housing 11. The main housing 11, the upper sealing cover 12, the lower sealing cover 13, the air inlet pipe 14 and the air outlet pipe 15 together form a housing mechanism 1 for providing space for filtering air.

[0058] As Figure 2 and Figure 4 , a filtering mechanism 2 is arranged between the upper sealing cover 12 and the lower sealing cover 13, and the filtering mechanism 2 is movably sleeved in the main housing 11. The filtering mechanism 2 is concentrically arranged with the main housing 11 for filtering air.

[0059] As Figures 2 - 5 , Figure 7 , a guiding mechanism 3 is arranged between the filtering mechanism 2 and the main housing 11, and the guiding mechanism 3 is located on the side of the filtering mechanism 2 facing the air inlet pipe 14 for protecting the side wall of the filtering mechanism 2. When the air inlet pipe 14 intakes air, the guiding mechanism 3 can guide the air flow to move circumferentially along the inner wall of the main housing 11 to reduce the air flow impact force on the side wall of the filtering mechanism 2 facing the air inlet pipe 14, thereby preventing the filter element 24 from being damaged and prolonging the service life of the filter element 24. Specifically, as Figure 7 and Figure 13, the guiding mechanism 3 includes a guide plate 31. The top end of the guide plate 31 is attached to the upper sealing cover 12, and the bottom end of the guide plate 31 is attached to the lower sealing cover 13, ensuring the stability of the guide plate 31 disposed within the housing mechanism 1. The shape of the guide plate 31 is arc-shaped, and the inner circle of the guide plate 31 is adapted to the outer circle of the filtering mechanism 2, capable of fully protecting the side wall of the filtering mechanism 2 facing the air inlet pipe 14. A plurality of guide grooves are formed on the outer circle of the guide plate 31, and threaded grooves are formed on the inner walls of the guide grooves. The guide grooves are arranged in a vertical array, capable of guiding the air flow blocked by the guide plate 31, causing the air flow to perform a self-rotating movement when moving circumferentially along the main housing 11. As a result, some dust with a large mass fails to pass through the filter element 24 with the air due to inertia and adheres to the inner wall of the main housing 11, effectively reducing the filtering pressure of the filter element 24. One end of the guide rail 32 is fixedly connected to the inner wall of the main housing 11, and the other end of the guide rail 32 is attached to the filtering mechanism 2. The number of guide rails 32 is four, and the four guide rails 32 are respectively disposed at the four corners of the guide plate 31. A guide hole is formed in the middle of the guide rail 32, and the guide rail 32 is movably clamped with the guide plate 31 through the guide hole, further ensuring the stability of the guide plate 31 disposed within the housing mechanism 1. A spring is disposed inside the guide rail 32, and the guide plate 31 is connected to the main housing 11 through the spring. When the guide plate 31 is not affected by wind force, under the pulling force of the spring, the guide plate 31 approaches the air inlet pipe 14. When the guide plate 31 is affected by wind force, the guide plate 31 overcomes the spring pulling force and approaches the filtering mechanism 2, thereby providing assistance for cleaning the dust and impurities adhering to the filtering mechanism 2.

[0060] Embodiment 2, on the basis of Embodiment 1, as Figures 2 - 3 , the guiding mechanism 3 further includes a cleaning assembly 4. A plurality of cleaning assemblies 4 are movably disposed on the guide plate 31 for cleaning the side wall of the filtering mechanism 2. As Figures 15 - 16 , the cleaning assembly 4 includes a connecting rod 41. A connection hole is formed on the wall surface of the guide plate 31 located inside the guide groove, and the guide plate 31 is movably clamped with the connecting rod 41 through the connection hole. The number of connecting rods 41 is several, and the several connecting rods 41 are arranged around the guide plate 31, enabling the cleaning assembly 4 to fully cover the filtering mechanism 2 and clean the dust on the filtering mechanism 2. The shape of the connection hole is large at both ends and small in the middle, enabling the connecting rod 41 to swing up and down along the connection hole, thereby preparing for fully cleaning the side wall of the filtering mechanism 2. One end of the connecting rod 41 is fixedly connected with a connecting member 42, and the connecting member 42 is located inside the guide groove. The shape of the connecting member 42 can be set according to requirements to ensure that the connecting member 42 can fully contact air flows in different directions. The other end of the connecting rod 41 is fixedly connected with a connecting block 43, and the connecting block 43 is located inside the inner circle of the guide plate 31. Cleaning hairs are provided on the connecting block 43. When the air flow rotates spirally in the guide groove, the air flow can push the connecting member 42 to swing up and down, and drive the connecting rod 41 and the connecting block 43 to swing, thereby expanding the scanning area of the cleaning assembly 4 and realizing the full cleaning of the side wall of the filtering mechanism 2 by the cleaning hairs.

[0061] Example 3. On the basis of Example 2, as Figures 2 - 5 , the filtering mechanism 2 includes a fixing plate 21, as Figure 9 , the fixing plate 21 is annular, and the inner ring of the fixing plate 21 is movably sleeved on the upper end of the air outlet pipe 15, which can ensure that the filtering mechanism 2 and the air outlet pipe 15 are concentrically arranged. The top surface height of the fixing plate 21 is equal to the top surface height of the air outlet pipe 15, which can ensure the stability of the fixing plate 21 sleeved on the air outlet pipe 15, as Figures 11 - 12 , an outer fixing rod 22 is fixedly connected to the outer side of the top end of the fixing plate 21. The number of the outer fixing rods 22 is several, and several outer fixing rods 22 are evenly arranged around the fixing plate 21. An inner fixing rod 23 is fixedly connected to the inner side of the top end of the fixing plate 21. The number of the inner fixing rods 23 is the same as that of the outer fixing rods 22, and several inner fixing rods 23 are evenly arranged around the fixing plate 21. The inner fixing rods 23 and the outer fixing rods 22 are alternately arranged, which helps to provide conditions for supporting and fixing the filter element 24, as Figure 10 , the movable plate 25 is circular plate-shaped, and the diameter of the movable plate 25 is equal to the outer diameter of the fixing plate 21. A top groove is opened at the bottom end of the movable plate 25, and the movable plate 25 is movably clamped with the outer fixing rod 22 and the inner fixing rod 23 through the top groove, so that the fixing plate 21, the outer fixing rod 22, the inner fixing rod 23 and the movable plate 25 form a complete whole, which is convenient for limiting and fixing the filter element 24, as Figure 11 , the filter element 24 is movably arranged between the fixing plate 21 and the movable plate 25, and the filter element 24 is of a folded annular design, which can effectively increase the filtering area and enhance the filtering effect. The lengths of the outer fixing rod 22 and the inner fixing rod 23 are equal, and the outer fixing rod 22 and the inner fixing rod 23 are longer than the length of the filter element 24, so that while the movable plate 25 is stably supported by the outer fixing rod 22 and the inner fixing rod 23, it can fully fit with the filter element 24 to prevent the filtering mechanism 2 from filtering air insufficiently. A fixing groove is opened on one side of the outer fixing rod 22, and the outer fixing rod 22 is movably clamped with the outer side edge of the filter element 24 through the fixing groove. A fixing groove is opened on one side of the inner fixing rod 23, and the inner fixing rod 23 is movably clamped with the inner side edge of the filter element 24 through the fixing groove. Thus, the outer fixing rod 22 and the inner fixing rod 23 can limit the edges of the filter element 24, keep the layers of the filter element 24 separated, and improve the stability of the position and posture of the filter element 24. It can not only avoid the problem of reduced filtering effect caused by the adhesion of the filter element 24 during long-term use, but also facilitate the disassembly and replacement of the filter element 24, and can also prepare for the stable self-rotation of the filter element 24, as Figure 11 , the bottom end of the movable column 26 is fixedly connected to the center of the top end of the movable plate 25, and the top end of the movable column 26 is movably clamped with the inner bottom end of the upper sealing cover 12. When the upper sealing cover 12 is installed on the main housing 11, the filtering mechanism 2 as a whole can be stably clamped by the upper sealing cover 12 and the lower sealing cover 13, asFigure 9 , a movable groove is formed at the bottom end of the fixing plate 21, and the fixing plate 21 is movably clamped with the movable ball 27 through the movable groove. The number of the movable balls 27 is several, and several movable balls 27 are uniformly arranged around the fixing plate 21, which can reduce the frictional resistance when the fixing plate 21 rotates by itself. Three annular grooves are formed at the top end of the lower sealing cover 13, and the outermost and innermost annular grooves are movably sleeved with the bottom end of the fixing plate 21, and the middle annular groove is in contact with the bottom end of the movable ball 27. By means of the arrangement of the annular grooves, not only the stability of the fixing plate 21 arranged on the lower sealing cover 13 is enhanced, but also through the three-layer design, dust and impurities can be effectively blocked from moving towards the air outlet pipe 15, and the service life of the device is improved.

[0062] Embodiment 4, on the basis of Embodiment 3, as Figures 13 - 14 , a plurality of tooth grooves are formed on the side wall of the movable column 26 below the upper sealing cover 12, which can provide conditions for the rotation of the movable column 26.

[0063] An air filter applicable to a new energy internal combustion engine further includes a movable push plate 5, as Figures 13 - 14 , the movable push plate 5 is placed on the top end of the movable plate 25, and the movable push plate 5 is located behind the movable column 26. One end of the movable push plate 5 is movably clamped with the top end of the guide plate 31 through an inverted "concave" clamping member. When the guide plate 31 moves, the guide plate 31 can drive the movable push plate 5 to move synchronously. A plurality of connecting grooves are formed on one side of the movable push plate 5 close to the movable column 26, and the movable push plate 5 is movably hinged with the tooth block 7 through the connecting grooves. The movable push plate 5 is meshed with the tooth grooves of the movable column 26 through the tooth block 7. When the guide plate 31 and the movable push plate 5 move synchronously, the tooth block 7 on the movable push plate 5 can push the movable column 26 to rotate. The size of the connecting groove is larger than that of the tooth block 7, and the left side wall surface of the connecting groove and the left side wall of the tooth block 7 have the same magnetism. Through the magnetic repulsion force, the tooth block 7 can be pushed to be in a vertical state in the connecting groove and meshed with the movable column 26. When the tooth block 7 and the movable column 26 are in a meshed state, the right side wall of the tooth block 7 is attached to the right side wall of the connecting groove, and the left side wall of the tooth block 7 is not attached to the left side wall of the connecting groove. At this time, if the movable push plate 5 is pushed to the left, the tooth block 7 is blocked by the right side wall of the connecting groove and cannot deflect, so that the tooth block 7 maintains a vertical state and can overcome the resistance of the movable column 26 to push the movable column 26 to rotate. If the movable push plate 5 is pushed to the right, the tooth block 7 will deflect to the left side of the connecting groove under the action of the resistance of the movable column 26 and thus is not meshed with the tooth groove of the movable column 26. Therefore, when the guide plate 31 moves towards the filter element 24, the tooth block 7 on the movable push plate 5 is meshed with the movable column 26, thereby driving the whole filtering mechanism 2 to rotate, realizing the change of the position of the side wall of the filter element 24, so that the cleaning component 4 on the guide plate 31 can clean each position of the filter element 24, and further improving the filtering efficiency of the filter element 24.

[0064] An air filter applicable to a new energy internal combustion engine further includes a fixed push plate 6, as Figures 13 - 14 , the fixed push plate 6 is fixedly connected to the inner bottom end of the upper sealing cover 12, and the fixed push plate 6 is located on the front side of the movable column 26, effectively ensuring that the fixed push plate 6 will always remain stationary. A number of connecting grooves are provided on one side of the fixed push plate 6 close to the movable column 26, and the fixed push plate 6 is movably hinged to the tooth block 7 through the connecting grooves. The fixed push plate 6 is meshed with the tooth groove of the movable column 26 through the tooth block 7. The size of the connecting groove is larger than that of the tooth block 7, and the right side wall surface of the connecting groove and the right side wall of the tooth block 7 have the same magnetism. The tooth block 7 can be pushed by magnetic repulsion to be in a vertical state in the connecting groove and meshed with the movable column 26. When the tooth block 7 and the movable column 26 are in a meshed state, the left side wall of the tooth block 7 is attached to the left side wall of the connecting groove, and the right side wall of the tooth block 7 is not attached to the right side wall of the connecting groove. At this time, if the movable push plate 5 is pushed to the left, since the movable column 26 will have a counterclockwise rotational force under the action of the movable push plate 5, the tooth block 7 in the fixed push plate 6 will be deflected to the right in the connecting groove under the thrust, so that the tooth block 7 on the fixed push plate 6 is not meshed with the tooth groove of the movable column 26, facilitating the movable push plate 5 to push the movable column 26 to rotate. If the movable push plate 5 is pushed to the right, since the tooth block 7 on the fixed push plate 6 is in a vertical state meshed with the movable column 26 and cannot be deflected to the left, the movable column 26 cannot rotate clockwise under the thrust of the movable push plate 5. Thus, when the guide plate 31 moves away from the filter element 24, the tooth block 7 on the fixed push plate 6 is meshed with the movable column 26, making the whole filtering mechanism 2 not rotate, effectively ensuring that the filtering mechanism 2 rotates only in one direction, and further ensuring that all parts of the filter element 24 can be fully cleaned.

[0065] The working principle of the usage method of the present invention is as follows:

[0066] When the device is assembled, first, the filter element 24 is sleeved on the fixed plate 21, and the lower end of the filter element 24 is fitted with the fixed plate 21. When sleeving, note that the edges and corners of the filter element 24 should be snap-connected to the outer fixing rod 22 and the inner fixing rod 23 one by one. Then, the movable plate 25 is installed at the top ends of the outer fixing rod 22 and the inner fixing rod 23, and the upper end of the filter element 24 is fitted with the movable plate 25. Thus, the fixed plate 21, the outer fixing rod 22, the inner fixing rod 23, and the movable plate 25 fix and support the filter element 24, keeping the layers of the filter element 24 separated, improving the stability of the position and attitude of the filter element 24. This can not only avoid the problem of reduced filtration effect caused by the adhesion of the filter element 24 during long-term use, but also facilitate the disassembly and replacement of the filter element 24, and can also prepare for the self-rotation of the filter element 24. Then, the lower sealing cover 13 is installed at the bottom end of the main housing 11, the guide plate 31 is installed in the main housing 11, and the guide plate 31 is movably snap-connected to the guide rail 32. The filtering mechanism 2 is installed in the main housing 11, and the fixed plate 21 is movably snap-connected to the lower sealing cover 13. Then, the movable push plate 5 is placed on the movable plate 25, and the movable push plate 5 is connected to the guide plate 31. Finally, the upper sealing cover 12 is installed at the top end of the main housing 11 to fix the filtering mechanism 2 and the guiding mechanism 3. Thus, the assembly of the device is completed.

[0067] When air enters the main housing 11 through the air inlet pipe 14, since there is a guide plate 31 between the air inlet pipe 14 and the filtering mechanism 2, the air flow is blocked by the guide plate 31 and cannot directly face the filtering mechanism 2, effectively protecting the side wall of the filter element 24 facing the air inlet pipe 14. The side wall of the filter element 24 does not need to bear the instantaneous impact force when the air flow enters, thus preventing the filter element 24 from being damaged and extending the service life of the filter element 24. The blocked air flow moves along the guide groove of the guide plate 31. Since a spiral groove is provided on the guide groove, it effectively promotes the air flow to rotate self when moving to both sides of the guide plate 31. Thus, some dust with large mass cannot pass through the filter element 24 with the air in time due to inertia and adheres to the inner wall of the main housing 11, effectively reducing the filtration pressure of the filter element 24. At the same time, due to the thrust of the air flow, the guide plate 31 moves closer to the filtering mechanism 2. And since a cleaning component 4 is provided on the guide plate 31, the cleaning component 4 can be inserted into the filter element 24 for cleaning, realizing the full cleaning of the dust and impurities adhering to the side wall of the filter element 24, improving the filtration effect and efficiency of the filter element 24 for air, thus preventing the continuous accumulation of dust and impurities on the outer wall of the filter element 24 from causing a decrease in the filtration effect. Also, since the air flow on the guide plate 31 rotates self, it can push the cleaning component 4 to swing up and down, realizing the full cleaning of the outer wall of the filter element 24.

[0068] When the guide plate 31 approaches the filtering mechanism 2 under the action of wind force, the tooth block 7 on the movable push plate 5 meshes with the movable column 26, thereby driving the overall rotation of the filtering mechanism 2 to realize the change of the position of the side wall of the filter element 24. This not only enables the cleaning component 4 on the guide plate 31 to clean each position of the filter element 24, further improving the filtering efficiency of the filter element 24, but also changes the position of the filtering mechanism 2, so that the filtering mechanism 2 will not stay at the same position for a long time, thereby increasing the service life of the filtering mechanism 2. When the guide plate 31 approaches the intake pipe 14 under the action of the spring, the tooth block 7 on the fixed push plate 6 meshes with the movable column 26, causing the movable push plate 5 to move but the overall filtering mechanism 2 not to rotate, effectively ensuring that the filtering mechanism 2 rotates only in one direction and further ensuring that each part of the filter element 24 can be fully cleaned.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
