The following embodiments are used to illustrate the utility model.

[0027] like Figure 1 and Figure 2 As shown, an assembly structure includes: a ventilation pipe 21, the ventilation pipe 21 is a hollow circular tube, which is an existing technology and will not be described in detail here;

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the clamping structure can fix the air duct, and the clamping structure includes side blocks 30 and clamping arcs 37. The side blocks 30 are symmetrically arranged on both sides of the ventilation duct 21, and the clamping arcs 37 are movably connected to the wall surfaces of the side blocks 30. The clamping arcs 37 are also symmetrically arranged on both sides of the ventilation duct 21. The clamping structure also includes a front slider 33, a rear slider 34 and a push rod 36. The front slider 33 is slidably connected in the front slide groove 32, and the rear slider 34 is slidably connected in the rear slide groove 31. The front wall surface of the rear slider 34 is fixedly connected to the rear wall surface of the front slider 33, and one side wall surface of the push rod 36 is fixedly connected to the side wall surface of the front slider 33, and the other side wall surface of the push rod 36 is fixedly connected to the outer arc wall surface of the clamping arc 37 on the corresponding side, and the top of the push rod 36 is L-shaped, and the rear slide groove 31 can adapt to the sliding of the rear slider 34, and the front slide groove 32 can adapt to the sliding of the front slider 33.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the engaging structure further includes a slot 22, a rear slide slot 31 and a front slide slot 32. The slot 22 is provided on the outer wall of the ventilation pipe 21, the rear slide slot 31 is provided on the rear wall of the side block 30, and the front slide slot 32 is provided on the front wall of the side block 30. The inner arcs of the symmetrical arcs 37 can be staggered in the slot 22, and the front slide slot 32 and the rear slide slot 31 can form a convex groove. The engaging structure further includes a locking slot 35, a locking rod 38 and a connecting rod 39. The locking slot 35 runs through the top of the side block 30, the locking rod 38 is clamped in the locking slot 35, and the connecting rod 39 is fixedly connected to the top of the locking rod 38. The locking groove 35 is in the shape of a rectangular groove. A plurality of the same locking grooves 35 are evenly provided on the top of the front slider 33. Each locking groove 35 on the wall of the front slider 33 can be connected with the locking groove 35 on the wall of the side block 30 by sliding the front slider 33. The wall of each side block 30 is provided with a rear slide groove 31, a front slide groove 32, a front slider 33, a rear slider 34 and a push rod 36. The bottom of the connecting rod 39 is symmetrically fixedly connected with a locking rod 38. The bottom center of the connecting rod 39 can contact the top of the ventilation pipe 21. The symmetrical locking rods 38 enter the symmetrical locking grooves 35 on the wall of the side block 30 respectively.

[0030] When in use, firstly, the connecting rod 39 drives the locking rod 38 to unlock the position of the front slider 33. At this time, the air duct to be installed is sleeved on the wall of the ventilation duct 21. At this time, the front slider 33 is pushed toward the other front slider 33. The front slider 33 can drive the rear slider 34 to slide in the rear slide groove 31. The front slider 33 body will slide in the front slide groove 32. The front slider 33 can also drive the push rod 36 to move at the same time. The push rod 36 will drive the arc 37 to move toward the other arc 37. The front slider 33 on the wall of the side block 30 on the other side is also in this way. The symmetrical front sliders 33 can be adjusted at the same time. When the arc 37 moves toward the wall of the ventilation pipe 21, the outer wall of the ventilation pipe will be pressed against the clamping groove 22. After the clamping arc 37 has clamped the ventilation pipe on the wall of the ventilation pipe 21, the connecting rod 39 can drive the locking rod 38 to be inserted into the locking groove 35 on the wall of the symmetrical side block 30. When the locking rod 38 enters the locking groove 35 at the top of the side block 30, it will also directly pass through the locking groove 35 at the corresponding position of the wall of the front slide block 33, thereby fixing the position of the arc 37. At this time, the position of the ventilation pipe is fixed. When the ventilation pipe needs to be removed, the connecting rod 39 can drive the locking rod 38 to disengage from the locking groove 35. At this time, the ventilation pipe can be directly removed from the wall of the ventilation pipe 21.

[0031] In summary, by setting up the locking structure, the air duct can be installed quickly. The locking structure clamps the air duct to the wall of the ventilation duct 21 through the locking arc 37 which can adjust the position at the same time. The symmetrical inner arc surface of the locking arc 37 can just form a circle that fits the outer wall of the air duct, thereby fixing it to the outer wall of the ventilation duct 21. In this installation process, it is only necessary to move the front slider 33 and insert the locking rod 38 into the locking groove 35. When the air duct needs to be disassembled, the air duct can also be quickly removed from the wall of the ventilation duct 21. Therefore, compared with the prior art, this solution is faster and more convenient when installing the air duct, and there is no need to reserve additional tools for auxiliary installation.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the edge block 30 is in a rectangular block shape, the clamping arc 37 is a U-shaped rod with an opening toward the side, the openings of the symmetrical clamping arcs 37 face each other, and the inner wall surface of the clamping arc 37 can contact the wall surface of the ventilation pipe 21;

[0033] In actual use, when the symmetrical clamping arc 37 fixes the air duct to the outer wall of the ventilation pipe 21, the inner arc of the clamping arc 37 will make the outer wall of the air duct contact with the clamping groove 22, so as to fix the position of the air duct when it is sleeved on the outer wall of the ventilation pipe 21;

[0034] In summary, by providing symmetrical clamping arcs 37, air ducts of different sizes can be fixed on the outer wall of the ventilation duct 21, because the symmetrical clamping arcs 37 are staggered to adapt to circular air ducts of different sizes, thereby improving the application range of the device.

[0035] like Figure 1 As shown, an oil mist purifier comprises a purifier case (20) and all the above-mentioned assembly structures, wherein the ventilation pipe (21) is fixedly connected to the rear wall of the purifier case (20), and the side blocks (30) are symmetrically fixedly connected to the wall of the purifier case (20) on both sides of the ventilation pipe (21);

[0036] In summary, by setting up the assembly structure, the assembly speed of the oil mist purifier can be increased, and air ducts of different sizes can be installed on the wall of the oil mist purifier, which increases the range of choices when selecting assembly parts for the oil mist purifier.

[0037] Working principle: First, the connecting rod 39 drives the locking rod 38 to unlock the position of the front slider 33. At this time, the air duct to be installed is sleeved on the wall of the ventilation duct 21. At this time, the front slider 33 is pushed toward the other front slider 33. The front slider 33 can drive the rear slider 34 to slide in the rear slide groove 31. The front slider 33 body will slide in the front slide groove 32. The front slider 33 can also drive the push rod 36 to move at the same time. The push rod 36 will drive the arc 37 to move toward the other arc 37. The front slider 33 on the wall of the side block 30 on the other side is also in this way. The symmetrical front sliders 33 can be adjusted at the same time. When the locking block 38 moves toward the wall of the ventilation duct 21, the outer wall of the ventilation duct will be pressed against the clamping groove 22. After the clamping arc 37 has clamped the ventilation duct on the wall of the ventilation duct 21, the connecting rod 39 can drive the locking rod 38 to be inserted into the locking groove 35 on the wall of the symmetrical side block 30. When the locking rod 38 enters the locking groove 35 at the top of the side block 30, it will directly pass through the locking groove 35 at the corresponding position of the wall of the front slide block 33, thereby fixing the position of the clamping arc 37. At this time, the position of the ventilation duct is fixed. When the ventilation duct needs to be removed, the connecting rod 39 can drive the locking rod 38 to disengage from the locking groove 35. At this time, the ventilation duct can be directly removed from the wall of the ventilation duct 21.
