[0001] This utility model relates to an intake manifold filter mechanism, belonging to the field of intake manifold technology. Background Technology
[0002] In the intake system of engines and other equipment, the intake manifold is responsible for distributing air to each cylinder. However, the air may contain dust, impurities, and other particulate matter before entering the intake manifold. If these impurities enter the engine directly, they will cause wear and tear on internal engine components, affecting engine performance and lifespan. Most existing intake manifolds lack effective filtration devices, or the filters are inconvenient to replace or have poor filtration effects, failing to meet the high requirements for air quality. Utility Model Content
[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide an intake manifold filter mechanism that improves the filtration efficiency for impurities of different particle sizes, effectively ensures the quality of air entering the engine, reduces the wear of impurities on internal engine components, and extends the service life of the engine.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an intake manifold filter mechanism, comprising: The first intake manifold and the second intake manifold, with multiple intake manifolds arranged on the second intake manifold; A connecting pipe is disposed between the first intake main pipe and the second intake main pipe for connecting the first intake main pipe and the second intake main pipe; A filter assembly, which is detachably installed inside the connecting pipe, is used to filter the gas in the first intake manifold and the second intake manifold.
[0005] Preferably, the connecting pipe comprises: A fixing sleeve, the two ends of which are respectively connected to the first air intake pipe and the second air intake pipe, and a side groove is provided on the side wall of the fixing sleeve to facilitate the removal of the filter assembly from the fixing sleeve; A pressure plate, which is disposed in the side groove, is used to press the filter assembly into the fixed sleeve.
[0006] Preferably, the fixing sleeve has slots on both sides of the side groove; Two elastic plates are respectively provided on both sides of the pressure plate, and the outer wall of the elastic plate is provided with a locking block, which is movably engaged with the locking groove on the same side.
[0007] Preferably, the outer walls of the two elastic plates are provided with anti-slip textures.
[0008] Preferably, the filtering component includes: A sleeve, wherein the sleeve is disposed inside the connecting pipe; A filter screen, wherein the filter screen is disposed inside the sleeve; As the gas passes through the sleeve, the filter screen filters out impurities in the gas.
[0009] Preferably, multiple filter screens are provided, and the multiple filter screens are evenly distributed inside the sleeve.
[0010] Preferably, the mesh size of the multiple filters decreases sequentially from the side closest to the first air intake manifold toward the side closest to the second air intake manifold.
[0011] Preferably, the filter screen is cone-shaped, with the small end of the filter screen facing the first air intake manifold.
[0012] Preferably, the large end of the filter screen is provided with a ring plate, and the inside of the sleeve is provided with multiple partition sleeves, with the ring plate clamped between two corresponding partition sleeves.
[0013] Preferably, both the first and second air intake manifolds are provided with connecting nuts at the ends near the fixed sleeve. The connecting nuts are threadedly engaged with the side wall of the fixed sleeve to connect the first and second air intake manifolds to the fixed sleeve.
[0014] Compared with existing technologies: 1. This utility model incorporates multiple filters, with the mesh size decreasing sequentially from the side closest to the first air intake manifold towards the side closest to the second air intake manifold. This tiered filtration design allows for targeted filtration based on the size of impurity particles, intercepting larger particles first and then filtering smaller ones. This avoids the clogging problems that can occur with a single filter, while simultaneously improving filtration efficiency for impurities of different sizes. This effectively ensures the quality of air entering the engine, reduces wear and tear on internal engine components, and extends the engine's lifespan.
[0015] 2. The fixing sleeve of the connecting pipe in this utility model has a side groove, and the filter assembly can be detachably installed through the cooperation of the pressure plate, elastic plate, locking block, and locking groove. When the filter assembly needs to be replaced or cleaned after a period of use, the operator only needs to press the elastic plate to remove the pressure plate, and then easily take out the filter assembly from the side groove. This makes the disassembly and installation of the filter assembly very convenient and quick, without the need for complicated tools, greatly reducing maintenance and time costs, and improving the efficiency of equipment use.

[0018] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.
[0019] like Figures 1-5 As shown in this embodiment, an intake manifold filtration mechanism is provided, including a first intake main pipe 1 and a second intake main pipe 2, with a plurality of intake manifolds 3 arranged on the second intake main pipe 2; a connecting pipe 4 for connecting the first intake main pipe 1 and the second intake main pipe 2 is provided between the first intake main pipe 1 and the second intake main pipe 2; a filter assembly 5 for filtering the gas in the first intake main pipe 1 and the second intake main pipe 2 is detachably installed in the connecting pipe 4.
[0020] The connecting pipe 4 includes a fixing sleeve 401 and a pressure plate 402. The two ends of the fixing sleeve 401 are respectively connected to the first air intake pipe 1 and the second air intake pipe 2. A side groove 4011 is provided on the side wall of the fixing sleeve 401 to facilitate the removal of the filter assembly 5 from the fixing sleeve 401. The pressure plate 402 is provided in the side groove 4011 and is used to press the filter assembly 5 into the fixed sleeve 401.
[0021] The fixing sleeve 401 has slots 4012 on both sides of the side groove 4011; the pressure plate 402 has two elastic plates 4021 on each side, and the outer wall of the elastic plate 4021 is provided with a locking block 4022, which is movably engaged with the locking slot 4012 on the same side. The outer walls of the two elastic plates 4021 are provided with anti-slip texture.
[0022] The filter assembly 5 includes a sleeve 501 and a filter screen 502. The sleeve 501 is disposed inside the connecting pipe 4; the filter screen 502 is disposed inside the sleeve 501; when gas passes through the sleeve 501, the filter screen 502 filters impurities in the gas.
[0023] Multiple filters 502 are provided, and the multiple filters 502 are evenly distributed inside the sleeve 501.
[0024] The mesh size of the multiple filter screens 502 decreases sequentially from the side closest to the first air intake pipe 1 to the side of the second air intake pipe 2, which can achieve graded filtration of impurities of different particle sizes and improve the filtration effect.
[0025] The filter screen 502 is cone-shaped, with the small end of the filter screen 502 facing the first air intake pipe 1. This shape can increase the filtration area and make it easier for impurities to accumulate on the edge of the filter screen.
[0026] The large end of the filter screen 502 is provided with a ring plate 5021, and the inside of the sleeve 501 is provided with multiple partition sleeves 503. The ring plate 5021 is clamped between two corresponding partition sleeves 503, so that there is a certain gap between two adjacent filter screens 502, ensuring that the gas can pass through each filter screen smoothly.
[0027] Both the first intake manifold 1 and the second intake manifold 2 are provided with a connecting nut 6 at one end near the fixed sleeve 401. The connecting nut 6 is connected to the side wall of the fixed sleeve 401 by thread engagement, thereby connecting the first intake manifold 1, the second intake manifold 2 and the fixed sleeve 401.
[0028] Work process: When the engine is running, air enters from the first intake manifold 1 and passes through the filter assembly 5 inside the connecting pipe 4. At this time, multiple filters 502 filter impurities in the air in stages according to their mesh size. Larger impurities are first intercepted by the filter closest to the first intake manifold 1, while smaller impurities are filtered by subsequent filters with smaller mesh sizes. The filtered clean air is then distributed to each cylinder through multiple intake manifolds 3 on the second intake manifold 2, providing clean air to the engine and ensuring its normal operation. When it is necessary to replace or clean the filter assembly 5, the operator only needs to press the elastic plates 4021 on both sides of the pressure plate 402 to disengage the locking block 4022 from the locking groove 4012, then remove the pressure plate 402, and finally remove the filter assembly 5 from the side groove 4011 for replacement or cleaning. The operation is convenient and quick.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
