7. The gas path connection structure according to claim 5, characterized in that: At least one group of auxiliary connection mechanisms (9) is arranged in the accommodating cavity (42), and the auxiliary connection mechanism (9) includes a first suction body (91) arranged at the bottom of the accommodating cavity (42) and a second suction body (92) arranged on the second carrier (5) corresponding to the first suction body (91), and the first suction body (91) and the second suction body (92) have the characteristic of attracting each other; when assembling, the second connecting part (32) is inserted into the accommodating cavity (42), and the first suction body (91) and the second suction body (92) are attracted to each other, thereby playing an auxiliary connection role for the first connecting part (31) and the second connecting part (32).

8. The gas path connection structure according to claim 2, characterized in that: The first carrier (4) is provided with a T-shaped plug-in groove (44) along its length direction, and a lap platform (45) is formed on both sides of the first carrier (4) corresponding to the T-shaped plug-in groove (44), and a movable groove (46) is provided on the top of the lap platform (45), and an elastic sheet (47) is arranged in the movable groove (46) along the length direction of the T-shaped plug-in groove (44), one end of the elastic sheet (47) is a fixed end connected and fixed to the lap platform (45), and the other end is a free end, and the free end is bent to form a clamping portion (51), and in the absence of external force, the clamping portion (51) always has a tendency to move in a direction away from the movable groove (46); the second carrier (5) is arranged corresponding to the T-shaped plug-in groove (44), and a clamping edge (41) capable of clamping and cooperating with the clamping portion (51) is formed on both sides of the second carrier (5); During assembly, the second connecting portion (32) is inserted into the T-shaped insertion groove (44), and the two are fixedly connected by the engagement of the clamping edge (41) and the clamping portion (51); during disassembly, the second connecting portion (32) is pulled outward, and the clamping portion (51) is forced to move downward under the action of external force until it is disengaged from the clamping edge (41), and the first connecting portion (31) is separated from the second connecting portion (32).

9. The gas path connection structure according to claim 8, characterized in that: A reset member (49) is also provided in the movable groove (46), and the reset member (49) is provided below the elastic sheet (47); when the first connecting portion (31) and the second connecting portion (32) are disassembled, the second connecting portion (32) is pulled outward, and the clamping portion (51) is forced to move downward under the action of an external force and squeeze the reset member (49) until it is disengaged from the clamping edge (41), and the first connecting portion (31) and the second connecting portion (32) are separated, after which the reset member (49) naturally rebounds and assists in lifting the elastic sheet (47) to reset it.
