[0002] The intake pipe is the main intake path of the engine, responsible for introducing air from the intake port, filtering it through the air filter, and then delivering it to each cylinder. The intake pipe is mainly composed of the intake manifold and the intake manifold. Each cylinder has an intake manifold, which is responsible for distributing air from the intake manifold to each cylinder. The design of the intake manifold ensures that the intake distribution of each cylinder is reasonable and uniform. In multi-point electronic fuel injection engines, in order to eliminate intake fluctuations and ensure uniform intake of each cylinder, there are strict requirements on the shape and volume of the intake manifold and the intake manifold. The intake manifold and the intake manifold of some engines are made into one piece, while others are made separately and then connected with bolts. In addition, the angle and shape of the intake duct will also affect the intake effect.

When the oxygen contains impurities, it will affect subsequent use. The device does not filter the oxygen. When the oxygen contains impurities, it will affect subsequent use through the pipeline. Therefore, we need to propose an intake pipeline structure. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] An air intake pipeline structure includes a mounting block 1, a connecting pipe 2 is fixedly connected to the front end of the mounting block 1, an elastic plate 3 is fixedly installed inside the mounting block 1, a mounting plate 4 is connected to the inside of the mounting block 1, a rotating rod 5 is connected to the inside of the mounting plate 4 through a bearing, a fan blade 6 is fixedly connected to the front end of the rotating rod 5, a cleaning rod 7 is fixedly connected to the rear end of the rotating rod 5, a filter screen 8 is rotatably connected to the outer side of the cleaning rod 7, the filter screen 8 is fixedly connected to the mounting block 1, and an internal threaded pipe 9 is fixedly connected to the upper end of the mounting block 1.

[0026] Through the design of the elastic plate 3 , the elastic plate 3 and the connecting pipe 2 are in abutment with each other, and the elastic plate 3 can seal the connecting pipe 2 .

[0027] The interior of the internal threaded pipe 9 is connected to a first branch pipe 10 via threads, and a first pressure reducing valve 11 is provided on the first branch pipe 10 .

[0028] Through the design of the internal threaded tube 9, the internal threaded tube 9 is installed with the first branch pipe 10 through threads to fix the mounting block 1. At the same time, the first pressure reducing valve 11 reduces the pressure of the incoming oxygen to prevent the airflow entering the first branch pipe 10 from being too fast, causing impact on the inner wall of the first branch pipe 10 and damaging the first branch pipe 10, thereby protecting the first branch pipe 10.

[0029] One end of the first branch pipe 10 is fixedly connected to a first diverter block 12 , and a hemispherical groove is provided inside the first diverter block 12 .

[0030] Through the design of the first diverter block 12, a hemispherical groove is opened inside the first diverter block 12. When the airflow passes through the hemispherical groove, the direction of the airflow changes, thereby achieving a diverting effect.

[0031] The outer side of the first branch pipe 10 contacts with a support ring 13 , and the outer side of the support ring 13 is fixedly connected with a support rod 14 .

[0032] The support ring 13 is in the shape of a semicircular ring, and the two support rings 13 are connected by bolts.

[0033] Through the design of the support ring 13, a plurality of support rings 13 are provided, and each two support rings 13 form a group. A group of support rings 13 is fixed by bolts to fix a pipeline. At the same time, each two groups of support rings 13 are connected by a support rod 14. At the same time, the pipelines are connected at a right angle, and a right triangle is formed between the support ring 13, the support rod 14 and the pipeline. The triangle has stability, which can make the connection between the two pipelines more stable.

[0034] The outer side of the first branch pipe 10 is fixedly connected with the second branch pipe 15 , and the second branch pipe 15 is in contact with the support ring 13 .

[0035] Through the design of the first branch pipe 10 and the second branch pipe 15, the first branch pipe 10 and the second branch pipe 15 transport oxygen, and through the connection between the pipes at different angles, the oxygen can be transported to a designated location.

[0036] An air outlet pipe 16 is fixedly connected to the outer side of the second branch pipe 15 , and the air outlet pipe 16 is in contact with the support ring 13 .

[0037] Through the design of the second branch pipe 15, the two groups of second branch pipes 15 transport oxygen through the second diverter block 17 and guide it toward the outlet pipe 16, thereby solving the technical problem of mutual interference of air flow components caused by the air flow entering the opposite second branch pipe 15 when multiple second branch pipes 15 at the same level are connected to the outlet pipe 16 for air supply. The elimination of air flow interference makes the pressure of the oxygen compressor stable, which helps the smooth operation of the gas-using unit under the stable air flow state.

[0038] One end of the air outlet pipe 16 is fixedly connected to a second diverter block 17 , and a second pressure reducing valve 18 is provided on the air outlet pipe 16 .

[0039] Through the design of the air outlet pipe 16, the air outlet pipe 16 outputs oxygen, and the second pressure reducing valve 18 arranged on the air outlet pipe 16 reduces the pressure of oxygen entering the air outlet pipe 16, thereby realizing long-distance stable pressure transmission of the pipeline.

[0040] Working principle: when the utility model is used, the external pipeline or tank is connected through the connecting pipe 2, and the airflow enters the inside of the installation block 1 through the connecting pipe 2. When the oxygen passes through the elastic plate 3, the elastic plate 3 is opened. When the oxygen stops being transported, the elastic plate 3 seals the installation block 1 to prevent impurities from entering the air when the external pipeline is removed, so as to facilitate the collection of impurities. When the airflow passes through the inside of the installation block 1, it can drive the fan blades 6 to rotate, and the fan blades 6 drive the rotating rod 5 to rotate, and the rotating rod 5 drives the cleaning rod 7 to rotate. The cleaning rod 7 rotates on the surface of the filter screen 8 to clean the filter screen 8 to avoid clogging of the filter screen 8. When the airflow passes through the filter screen 8, the filter screen 8 filters the impurities in the airflow to prevent the impurities from entering the inside of the pipeline. After a period of use, the installation block 1 can be removed from the first branch pipe 10, and the elastic plate 3 can be removed to clean the inside of the installation block 1 to avoid the installation block 1 being inconvenient to clean.

[0041] When the oxygen in the first branch pipe 10 is uniformly sent to the outlet pipe 16 for output, the airflow will pass through the second branch pipe 15 and enter the outlet pipe 16. Specifically, after the oxygen passes through the first branch pipe 10, it will enter the first diverter block 12, and after entering the first diverter block 12, it will pass through the second branch pipe 15, and then pass through the second diverter block 17 to be guided toward the outlet pipe 16, thereby solving the technical problem of airflow entering the opposite second branch pipe 15 when multiple second branches 15 at the same level are connected to the outlet pipe 16 for air supply, causing the airflow to interfere with each other. The airflow interference is eliminated, so that the pressure of the oxygen compressor is stable, thereby facilitating the stable operation of the gas-using unit under the stable airflow state;

[0042] When the airflow passes through the first branch pipe 10, the first pressure reducing valve 11 provided on the first branch pipe 10 reduces the pressure of the oxygen entering, so as to prevent the airflow entering the first branch pipe 10 from being too fast and impacting the inner wall of the first branch pipe 10 and causing damage to the first branch pipe 10. When the airflow passes through the outlet pipe 16, the second pressure reducing valve 18 provided on the outlet pipe 16 reduces the pressure of the oxygen entering the outlet pipe 16, so as to realize the stable pressure transmission of the pipeline over a long distance.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
