[0033] In this embodiment, at least four limiting rods 211 are disposed at the port of the embedding block 21 , which can be used to position the embedding block 21 and limit the function of the embedding block 21 .

[0034] In this embodiment, a slot 1111 cooperating with the limiting rod 211 is provided on the surface of the inner connecting layer 111, and the connecting seat 2 is embedded in the filter installation port 11 through the embedded block 21 to fit with the inner connecting layer 111, and at the same time, the limiting rod 211 at the port of the embedded block 21 will be inserted into the slot 1111 for connection. The above can make the limiting rod 211 at the port of the embedded block 21 inserted into the slot 1111, so that the embedded block 21 and the inner connecting layer 111 are more fitted.

[0035] In this embodiment, the limiting device 12 includes a latch stem 121 and a latch seat 122, the latch stem 121 is arranged in the latch seat 122 for movably connecting, the surface of the latch stem 121 is sleeved with a reset spring 1211, and a locking rod 1212 is also arranged at the bottom of the latch stem 121, the middle part of the latch seat 122 is arranged with a hollow structure slot, and slots matching the locking rod 1212 are arranged on both sides of the slot, and an interlayer 123 is arranged in the middle of the latch seat 122. The above can be disassembled by pulling the latch stem 121 to squeeze the reset spring 1211 and drive the locking rod 1212 to move upward.

[0036] In this embodiment, the surface of the embedded block 21 is also provided with a limiting groove 22 that matches the bottom of the latch stem 121. The limiting device 12 is inserted into the limiting groove 22 of the embedded block 21 of the protruding structure of the connecting seat 2 through the bottom of the latch stem 121 to perform a limiting connection. The above is to first pull the latch stem 121 to squeeze the reset spring 1211 and drive the locking rod 1212 to move upward. At this time, the locking rod 1212 is located in the interlayer 123. At this time, the latch stem 121 is rotated to make it stuck in the interlayer 123, and then the embedded block 21 of the protruding structure of the connecting seat 2 is embedded in the filter installation port, and the latch stem 121 is rotated again to make the locking rod 1212 located in the slot matching the locking rod 1212 and loosen it, so that the reset spring 1211 is reset, and the latch stem 121 is inserted into the limiting groove 22 of the embedded block 21 of the protruding structure of the connecting seat 2 for limiting connection, thereby limiting the position of the connecting seat 2.

[0039] Working principle:

[0040] First, pull the latch stem 121 of the limiting device 12 to squeeze the reset spring 1211 and drive the positioning rod 1212 to move upward. At this time, the positioning rod 1212 is located in the interlayer 123. At this time, rotate the latch stem 121 to make it stuck in the interlayer 123, and then embed the embedded block 21 of the protruding structure of the connecting seat 2 into the filter installation port. The limiting rod 211 at the port of the embedded block 21 will be inserted into the slot 1111, so that the embedded block 21 and the inner connecting layer 111 are more closely fitted. Rotate the latch stem 121 again to make the positioning rod 1212 in the slot matched with the positioning rod 1212 and release it. The reset spring 1211 is reset, and the latch stem 121 is inserted. The protruding structure of the connecting seat 2 is embedded in the limiting groove 22 of the embedded block 21 to limit the position of the connecting seat 2, and then the threaded connection is made with the internal threaded seat 23 on the other side of the connecting seat 2 through the threaded head 31 to be connected with the filter 3; this design is provided with a connecting seat, which can be limitedly connected with the filter mounting port on one side of the carburetor body through a limiting device arranged on the surface, so that the installation is simple and quick, relatively stable, and not easy to fall off.
