Description

Technical Field

[0001] This utility model relates to the field of equipment installation technology, specifically an easily detachable air intake pipe device. Background Technology

[0002] The air filter box and intake manifold together form the intake manifold system of a car engine. The intake manifold system works to ensure the engine receives clean and properly distributed air for combustion. Its core task is to filter the air; it is the first gateway for air entering the engine. Inside, it contains an air filter structure that removes dust, pollen, grit, insects, and other particulate contaminants from the air entering the engine. This prevents external impurities from wearing down the delicate piston rings, cylinder walls, valves, and fuel injectors, thus ensuring engine lifespan.

[0003] While preventing impurities from directly entering the engine cylinders, the filter element in the intake manifold can accumulate. If it is not maintained for a long time, it will increase intake resistance and affect engine performance. Regular cleaning or replacement of the filter element is required. However, the intake manifold is usually installed on the left side of the engine compartment, above the left front wheel, which means that the staff has to operate in a small space under the vehicle, which is inconvenient. In addition, the roughly square intake manifold is fixed to the vehicle structure with multiple bolts, which requires the staff to find and locate the bolts around the intake manifold, resulting in a slow disassembly speed. Utility Model Content

[0004] The purpose of this utility model is to provide an easily detachable air intake pipe device to solve the problem in the prior art that workers need to operate in a narrow space under the vehicle, find and locate multiple bolts around the air intake pipe device, and the disassembly speed of the air intake pipe device is slow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily detachable air intake pipe device, comprising an air intake pipe, an upper filter housing, and a lower filter housing. Two internally threaded components are fixedly connected to the front side of the upper filter housing, and two internally threaded components are fixedly connected to the front side of the lower filter housing. Limiting baffles are fixedly connected to the left and right sides of the upper filter housing. Multiple limiting hollow frames are fixedly connected to the rear side of the upper filter housing, and multiple snap-fit ​​plates are fixedly connected to the rear side of the lower filter housing. A filtering structure is provided between the upper and lower filter housings.

[0006] Preferably, the air intake pipe is fixedly connected to the outside of the upper shell of the filter box, the upper shell of the filter box is located at the top of the lower shell of the filter box, and an exhaust pipe is fixedly installed on one side of the lower shell of the filter box.

[0007] Preferably, the first internal threaded component and the second internal threaded component correspond one-to-one, and the first internal threaded component and the second internal threaded component on the same side are connected by a fixing bolt.

[0008] Preferably, the limiting baffle portion is fitted to the outer wall of the lower shell of the filter box, and the limiting baffle is configured as L-shaped.

[0009] Preferably, the limiting hollow frame and the snap-fit ​​plate correspond one-to-one, and the snap-fit ​​plate is disposed inside the limiting hollow frame and is interference-fitted with the limiting hollow frame.

[0010] Preferably, the filter structure includes a support frame disposed on the top of the lower shell of the filter box, a fixed vertical pipe fixedly connected inside the support frame, filter material fixedly connected inside the fixed vertical pipe, and a flow guide pipe disposed on the top of the filter material. The top of the lower shell of the filter box is formed with a snap-fit ​​groove, and the support frame fits into the snap-fit ​​groove.

[0011] Preferably, one side of the first flow guide pipe is fixedly connected to two second flow guide pipes, the bottom of the second flow guide pipe is fixedly connected to two atomizing nozzles, the top of the inner cavity of the filter box is fixedly connected to a micro water pump, the outlet of the micro water pump is fixedly connected to the first flow guide pipe with a one-way valve, the inlet of the micro water pump is fixedly connected to an inlet pipe, and the top of the inlet pipe penetrates the upper shell of the filter box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When this application is used, multiple limiting hollow frames, multiple snap-fit ​​plates, two limiting baffles, two internal threaded parts one and two internal threaded parts two work together to fix the upper shell of the filter box to the lower shell of the filter box. Only two fixing bolts are needed to complete the separation of the lower shell of the filter box from the upper shell of the filter box. The operator does not need to search for multiple fixing bolts between the lower shell of the filter box and the upper shell of the filter box in the limited operating space under the vehicle. Without reducing the number of stress points between the upper shell of the filter box and the lower shell of the filter box, the disassembly steps of the lower shell of the filter box are simplified, and the maintenance difficulty of the intake pipe device is reduced.

[0014] 2. When this application is used, after the vehicle has been working for a period of time, the micro water pump is controlled to work for a period of time. After the micro water pump draws lubricating oil, it is delivered to the inside of the two guide pipes through the one-way valve and the first guide pipe. After the hydraulic pressure inside the second guide pipe increases, the atomizing nozzle atomizes the lubricating oil inside the second guide pipe and sprays it out. The atomized lubricating oil is sprayed onto the top of the filter material. The lubricating oil wets the filter material, increases the adsorption and filtration effect of the filter material on impurities, and ensures the air filtration and purification effect of the air intake pipe device composed of the intake pipe, the upper shell of the filter box, the lower shell of the filter box, the filter structure, the exhaust pipe, etc. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-6 As shown, this utility model provides a technical solution for an easily detachable air intake pipe device. The easily detachable air intake pipe device includes an air intake pipe 1, an upper filter housing 2, and a lower filter housing 6. Two internally threaded parts 3 are fixedly connected to the front side of the upper filter housing 2, and two internally threaded parts 9 are fixedly connected to the front side of the lower filter housing 6. Limiting baffles 4 are fixedly connected to the left and right sides of the upper filter housing 2. Multiple limiting hollow frames 5 are fixedly connected to the rear side of the upper filter housing 2, and multiple snap-fit ​​plates 8 are fixedly connected to the rear side of the lower filter housing 6. A filter structure is provided between the upper filter housing 2 and the lower filter housing 6.

[0024] Specifically, the intake pipe 1 is fixedly connected to the outside of the upper shell 2 of the filter box. The intake pipe 1 is connected to the outside and supplies air to the inside of the upper shell 2 of the filter box. The upper shell 2 of the filter box is located on the top of the lower shell 6 of the filter box. An exhaust pipe 7 is fixedly installed on one side of the lower shell 6 of the filter box. The exhaust pipe 7 is used to connect to the intake end of the car engine. The air is purified and filtered by the filter structure set between the upper shell 2 and the lower shell 6 of the filter box and then enters the inside of the lower shell 6 of the filter box. The clean air inside the lower shell 6 of the filter box flows to the car engine through the exhaust pipe 7, providing clean air for the car engine to work.

[0025] Specifically, the internal threaded component 3 and the internal threaded component 9 correspond one-to-one. The internal threaded component 3 and the internal threaded component 9 on the same side are connected by a fixing bolt 10. After aligning the internal threaded component 3 and the internal threaded component 9, the fixing bolt 10 is rotated from the bottom end of the internal threaded component 9 to the top end of the internal threaded component 3. The fixing bolt 10 fixes the internal threaded component 3 and the internal threaded component 9 together. The movement of the upper shell 2 of the filter box and the lower shell 6 of the filter box in the vertical direction, the horizontal direction, and the front and back direction are all restricted.

[0026] Specifically, the limiting baffle 4 is L-shaped. The limiting baffle 4 will not affect the relative displacement in the front-to-back direction between the lower shell 6 and the upper shell 2 of the filter box. The limiting baffle 4 is partially attached to the outer wall of the lower shell 6 of the filter box. Under the action of the limiting baffle 4, the lower shell 6 of the filter box cannot move left or right at the bottom of the upper shell 2 of the filter box. The limiting baffle 4 distributes the force on the internal threaded part 3, the internal threaded part 9 and the fixing bolt 10.

[0027] Specifically, the limiting hollow frame 5 and the snap-fit ​​plate 8 correspond one-to-one. The snap-fit ​​plate 8 is set inside the limiting hollow frame 5 and is interference-fitted with the limiting hollow frame 5. The snap-fit ​​plate 8 and the limiting hollow frame 5 work together to limit the up-down and left-right movement of the filter box upper shell 2, ensuring the stability of the installation between the filter box upper shell 2 and the filter box lower shell 6.

[0028] Specifically, in the filter structure, the support frame 11 is set at the top of the lower shell 6 of the filter box. The fixed vertical tube 13 is fixedly connected inside the support frame 11 and the filter material 14 is fixedly inserted inside. The top of the lower shell 6 of the filter box is formed with a snap-fit ​​groove 12. The support frame 11 fits into the snap-fit ​​groove 12. Under the action of the support frame 11 and the fixed vertical tube 13, the air inside the upper shell 2 of the filter box can enter the lower shell 6 of the filter box after passing through the filter material 14. The filter material 14 filters the dust and impurities in the air.

[0029] A guide pipe 17 is installed at the top of the filter media 14. Two guide pipes 18 are fixedly connected to one side of the guide pipe 17, and two atomizing nozzles 19 are fixedly connected to the bottom of each guide pipe 18. A micro water pump 15 is fixedly connected to the top of the inner cavity of the filter box upper shell 2. A one-way valve 16 is fixedly connected between the water outlet of the micro water pump 15 and the guide pipe 17. A water inlet pipe 20 is fixedly connected to the water inlet of the micro water pump 15. The top of the water inlet pipe 20 passes through the filter box upper shell 2 and is connected to the oil supply system. After the vehicle has been working for a period of time, the micro water pump 15 is controlled to work for a period of time. After pump 15 draws lubricating oil, it is delivered to the two guide pipes 18 through one-way valve 16 and guide pipe 17. After the hydraulic pressure inside the guide pipe 18 increases, the atomizing nozzle 19 atomizes the lubricating oil inside the guide pipe 18 and sprays it out. The atomized lubricating oil is sprayed onto the top of the filter material 14, and the lubricating oil wets the filter material 14, which increases the adsorption and filtration effect of the filter material 14 on impurities. This ensures the air filtration and purification effect of the air intake pipe device composed of the air intake pipe 1, the upper shell of the filter box 2, the lower shell of the filter box 6, the filter structure, and the exhaust pipe 7.

[0030] Working principle: When the filter material 14 needs to be replaced, rotate the two fixing bolts 10 so that the top of the fixing bolts 10 leaves the inside of the internal threaded part 3. Then pull the lower shell 6 of the filter box forward so that the snap-fit ​​plate 8 fixedly connected to the lower shell 6 of the filter box leaves the inside of the limiting hollow frame 5 fixedly connected to the upper shell 2 of the filter box. When the lower shell 6 of the filter box is separated from the limiting baffle 4, the disassembly of the lower shell 6 of the filter box can be completed. The upper shell 2 of the filter box and the lower shell 6 of the filter box are fixedly installed by the cooperation of multiple limiting hollow frames 5, multiple snap-fit ​​plates 8, two limiting baffles 4, two internal threaded parts 1 and two internal threaded parts 2. Only two fixing bolts 10 are needed to complete the separation of the lower shell 6 of the filter box and the upper shell 2 of the filter box. The operator does not need to search for multiple fixing bolts 10 between the lower shell 6 of the filter box and the upper shell 2 of the filter box in the limited operating space under the vehicle. Without reducing the connection stress points between the upper shell 2 of the filter box and the lower shell 6 of the filter box, the disassembly steps of the lower shell 6 of the filter box are simplified, and the maintenance difficulty of the intake pipe device is reduced.

[0031] Press the support frame 11 on the outside of the new filter media 14 into the snap-fit ​​groove 12. The support frame 11 is interference-fitted with the lower shell 6 of the filter box. Since the height of the fixed vertical tube 13 and the filter media 14 at the top of the support frame 11 is limited, and the size of the fixed vertical tube 13 and the filter media 14 is smaller than the inner cavity size of the upper shell 2 of the filter box, the lower shell 6 of the filter box can be pushed from bottom to top first, so that the fixed vertical tube 13 and the filter media 14 enter the interior of the upper shell 2 of the filter box. Then push the lower shell 6 of the filter box backward, so that the snap-fit ​​plate 8 enters the interior of the limiting hollow frame 5. When the second internal thread part 9 is aligned with the first internal thread part 3, rotate the fixing bolt 10 through the second internal thread part 9 and the first internal thread part 3 to complete the replacement and installation of the filter media 14. The lower shell 6 of the filter box and the upper shell 2 of the filter box can be fixed together quickly and stably.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
