A fixed sleeve 601 is installed on the inner side of the limiting block 602, and the fixed sleeve 601 is located outside the sealing end 302.

[0026] Through the above technical solution, the inner combination shell 3 can be hermetically combined with the outer shell 1. The sealing end 302 at the end can increase the sealing performance through extrusion. The internal rotating rod 5 can drive the combination screw 502 and the threaded sleeve 102 to be combined by rotation. By rotating, the sealing end 302 can be extruded to improve the sealing performance. By disassembling in the reverse direction, the inner combination shell 3 can be separated from the outer shell 1, which is convenient for disassembly and maintenance of the internal structure.

[0027] Through the above technical solution, by setting the limit bracket 2, the intake insertion tube 103 on the inner side can be restricted, and at the same time, it can assist the intake insertion tube 103 to perform flipping adjustment. The fixing sleeve 601 on the front is installed on the outside of the sealing end 302, and the limit block 602 can move along the inside of the welding bracket 6. When controlling the extraction of the inner combination shell 3, the limit block 602 will automatically separate from the welding bracket 6. After separation, the intake insertion tube 103 can be controlled to flip along the limit bracket 2, and directly extracting the inner combination shell 3 can perform maintenance without having to disassemble the entire outer shell 1, shortening the time spent.

[0028] Specifically, a connecting hose 104 is installed on the back of the intake insertion tube 103, and a splicing tube 105 is installed on the back of the connecting hose 104.

[0029] Through the above technical solution, the connecting hose 104 is soft and deformable, which is convenient for the outer shell 1 to perform flipping angle adjustment. The splicing tube 105 is used to connect to the inside of the vehicle.

[0030] Specifically, a positioning plate 203 is installed on the top of the limit bracket 2, and reinforcing angle seats 202 are installed on both sides of the positioning plate 203. The reinforcing angle seats 202 are located on both sides of the limit bracket 2.

[0032] Specifically, an exhaust pipe 303 is installed on the front of the sealing end 302, and a group of completely sealed partitions 4 are installed on the inner side of the inner combination shell 3.

[0033] Through the above technical solution, the exhaust pipe 303 can be used to discharge the internal waste gas, and the completely sealed partition 4 can play a good role in sealing and restricting the inner silencing pipe 401.

[0034] Specifically, two groups of perforated sealed partitions 403 are installed on the inner side of the inner combination shell 3, and the perforated sealed partitions 403 are located outside the intake insertion tube 103. Six groups of return pipes 402 are arranged on the inner side of the middle perforated sealed partition 403, and six groups of silencing pipes 401 are arranged on the inner sides of the completely sealed partition 4 and the middle perforated sealed partition 403.

[0035] Through the above technical solution, the opening inside the opening and sealing partition plate 403 can assist in splicing the air intake insertion tube 103. The waste gas can be introduced into the back space by using the return pipe 402, and then the waste gas can be silenced by the silencing pipe 401.

[0036] Specifically, a sealing screw head 501 is installed on the front surface of the rotating rod 5, and the sealing screw head 501 is located on the front surface of the sealing end 302.

[0037] Through the above technical solution, the sealing screw head 501 can control the rotation of the rotating rod 5 through rotation for adjustment, and the outer shell 1 and the inner combined shell 3 can be spliced by adjustment.

[0038] Specifically, a limiting groove 603 is formed inside the welding bracket 6, and the limiting groove 603 is located outside the limiting block 602.

[0039] Through the above technical solution, the limiting groove 603 can provide a limit for the inner limiting block 602, which is convenient for splicing and keeping the outer shell 1 fixed under the vehicle.

[0040] During use, first, when maintenance is required, the rotating rod 5 can be driven to rotate by the sealing screw head 501. During the rotation process, the sealing screw head 501 will be separated from the threaded sleeve 102, and then the inner combined shell 3 can be pulled out. After being pulled out, it can be disassembled. After disassembly, after the limiting block 602 is separated from the limiting groove 603, the air intake insertion tube 103 can be flipped along the limiting bracket 2, and finally it can be removed for maintenance.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit, and the scope is defined by the appended claims and their equivalents.
