Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an anti-clogging multi-channel intake pipe. Background Technology

[0002] The intake system of a car engine is a key system that provides clean air to the engine and precisely controls the intake air volume. Its core function is to ensure the optimal mixing of air and fuel, thereby improving combustion efficiency and power output.

[0003] In construction machinery, agricultural equipment, military vehicles, or vehicles that operate in harsh environments, the air intake is often blocked by foreign objects such as leaves, plastic bags, snow, or mud. However, existing air intake pipes usually only have a single channel structure. Once the channel is blocked, it can lead to a decrease in engine power or even stalling, and in severe cases, it may cause engine damage. Utility Model Content

[0004] This invention provides an anti-clogging multi-channel suction tube, which solves the technical problems in the prior art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A clog-resistant multi-channel intake tube includes an inner tube with an outer tube nested around it. A fixed baffle is provided between the ends of the inner tube and the outer tube, and the fixed baffle has several sets of first through holes. A movable retaining ring is provided between the ends of the inner tube and the outer tube, and is slidably sleeved on the outside of the inner tube. The movable retaining ring has several sets of second through holes. An elastic pushing component acting on the movable retaining ring is also provided in the spare channel formed between the inner tube and the outer tube.

[0007] Furthermore, the elastic pushing assembly includes a fixing ring fixedly connected between the ends of the inner tube and the outer tube, and a spring sleeved on the surface of the inner tube and in a compressed state, with the two ends of the spring respectively abutting between the fixing ring and the movable retaining ring.

[0008] Furthermore, several groups of the first through holes are evenly distributed around the fixed baffle, and the second through holes are staggered from the first through holes on the fixed baffle.

[0009] Furthermore, a spline is provided on the inner wall of the inner tube, and a keyway that matches the spline is provided on the edge of the movable retaining ring.

[0010] Furthermore, both the inner tube and the outer tube are made of stainless steel.

[0011] Furthermore, a connecting bracket is fixedly connected to the outer side of the outer tube, and the connecting bracket has screw holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the arrangement of the inner and outer pipes allows the intake pipe to form a main channel and a backup channel for gas passage. During normal operation, the main channel inside the inner pipe is unobstructed, and the negative pressure generated by the engine allows air to be drawn in through the main channel inside the inner pipe. When the main channel inside the inner pipe is blocked, the movable retaining ring can slide towards the inside of the inner and outer pipes under the increased negative pressure, thereby separating the movable retaining ring from the fixed baffle. Air can then be drawn into the backup channel through the fixed baffle and the movable retaining ring, keeping the backup channel open and thus ensuring the normal operation of the engine.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A multi-channel anti-clogging suction tube includes an inner tube 1 and an outer tube 2 nested around it. The interior of the inner tube 1 serves as the main channel for gas flow, while the space between the inner tube 1 and the outer tube 2 is a backup channel. A fixed baffle 3 is provided between the ends of the inner tube 1 and the outer tube 2. The fixed baffle 3 has several sets of first through holes 4, which are evenly distributed around the fixed baffle 3. A movable retaining ring 5 is provided between the ends of the inner tube 1 and the outer tube 2, slidingly fitted onto the outside of the inner tube 1. The movable retaining ring 5 has several sets of second through holes 6, which are offset from the first through holes 4 on the fixed baffle 3. When the movable retaining ring 5 slides outward from the inner tube 1 and the outer tube 2, it abuts against the fixed baffle 3, thus blocking the second through holes 6 from the first through holes 4, preventing gas from being drawn into the inner tube 1 and the outer tube 2. In the backup channel formed between the inner tube 1 and the outer tube 2, the backup channel is in a closed state. When the movable baffle 5 slides towards the inner side of the inner tube 1 and the outer tube 2, the movable baffle 5 will move away from the fixed baffle 3, creating a certain gap between them. At this time, the second through hole 6 and the first through hole 4 are no longer mutually blocked, and the gas can be drawn into the backup channel through the fixed baffle 3 and the movable baffle 5, and the backup channel is in an open state. In addition, an elastic pushing component acting on the movable baffle 5 is also provided in the backup channel formed between the inner tube 1 and the outer tube 2. The elastic pushing component can always generate an elastic pushing force on the movable baffle 5 to move outward towards the inner tube 1 and the outer tube 2, so that the movable baffle 5 can remain in contact with the fixed baffle 3 under the pushing action, thereby keeping the backup channel formed between the inner tube 1 and the outer tube 2 in a closed state.

[0022] During normal operation, the main passage inside the inner tube 1 is unobstructed, while the movable retaining ring 5, under the action of the elastic push assembly, abuts against the fixed baffle 3, thus closing the spare passage between the inner tube 1 and the outer tube 2. At this time, the negative pressure generated by the engine allows air to be drawn in through the main passage inside the inner tube 1. However, when the main passage inside the inner tube 1 is blocked, the negative pressure at the rear ends of the inner tube 1 and the outer tube 2 increases sharply. Because the main passage inside the inner tube 1 is blocked and closed, this increased negative pressure acts on the movable retaining ring 5, which slides between the ends of the inner tube 1 and the outer tube 2, generating an internal suction force to overcome the elastic push assembly's action on the movable retaining ring 5. The generated elastic thrust allows the movable retaining ring 5 to slide towards the inside of the inner tube 1 and outer tube 2 under the increased negative pressure, thus separating the movable retaining ring 5 from the fixed baffle 3. At this time, since the second through hole 6 and the first through hole 4 are no longer mutually blocked, air can be drawn into the spare passage through the fixed baffle 3 and the movable retaining ring 5, keeping the spare passage open and ensuring the normal operation of the engine. When the blockage of the main passage inside the inner tube 1 is cleared, the negative pressure at the rear end of the inner tube 1 and outer tube 2 returns to normal, and the elastic thrust generated by the elastic thrust assembly drives the movable retaining ring 5 to reset, thus closing the spare passage again.

[0023] For further details, please refer to Figure 2-4 The elastic pushing assembly includes a fixed ring 7 fixedly connected between the ends of the inner tube 1 and the outer tube 2, and a spring 8 sleeved on the surface of the inner tube 1 and in a compressed state. The two ends of the spring 8 respectively abut against the fixed ring 7 and the movable retaining ring 5. When the spring 8 is compressed, it can generate an elastic force on the movable retaining ring 5, so that the movable retaining ring 5 can always be subjected to an elastic pushing force that moves towards the outside of the inner tube 1 and the outer tube 2.

[0024] For further details, please refer to Figure 3 and Figure 4 The inner wall of the inner tube 1 is provided with a spline 9, and the edge of the movable retaining ring 5 is provided with a keyway 10 that matches the spline 9. While the movable retaining ring 5 slides between the inner tube 1 and the outer tube 2, the spline 9 and the keyway 10 can guide the movable retaining ring 5, thereby preventing the movable retaining ring 5 from deflecting in the spare channel between the inner tube 1 and the outer tube 2, and ensuring that the second through hole 6 on the movable retaining ring 5 and the first through hole 4 on the fixed baffle 3 are always kept in a staggered state.

[0025] Furthermore, both the inner tube 1 and the outer tube 2 are made of stainless steel, which has high strength, is not easily deformed under external force, and is not easily corroded, thus having a long service life.

[0026] For further details, please refer to Figure 1The outer tube 2 is fixedly connected to a connecting bracket 11, and a screw hole 12 is provided on the connecting bracket 11. The entire air intake tube can be fixedly installed inside the car by screws through the connecting bracket 11 and the screw hole 12, so as to avoid the structure from shifting due to the vibration of the car and ensure the stability of the air intake tube.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
