In addition, in the present embodiment, as shown in fig. 14, a section of the operating rod 2 located between the pivot limiting mechanism 3 and the air door 22 is a straight rod, an acute angle included angle between a plane of the air door 22 and a side surface of the straight rod is 72 °, an acute angle included angle between a center line of the handle 21 passing through the center of the rotating shaft 33 and a side edge of the straight rod is 9 °, an acute angle included angle between a plane of the fresh air inlet 11 and a horizontal plane is 18 °, i.e., 90 ° to 72 °, and therefore, when the operating rod 2 is controlled to rotate until the straight rod is located in the vertical direction, the air door 22 is just abutted against and sealed with the fresh air inlet 11.

Referring to fig. 9, 10, 12 and 13, for example, when the operating rod 2 is in an operating state, when the user needs to open the fresh air inlet 11, the user only needs to rotate the handle 21 on the operating rod 2 to the right or counterclockwise until the first limit surface 3211 of the protrusion 321 disposed on the operating rod 2 contacts the second limit surface 411 of the guide boss 41 disposed on, for example, the damper bracket 12 (described further below) (as shown in fig. 9 and 12); when the user needs to close the fresh air inlet 11, the handle 21 on the operating lever 2 is rotated leftwards or clockwise, until the damper 22 provided on the operating lever 2 contacts with a side casing plate 131 (described further below) of the volute 13 (as shown in fig. 10 and 13). From top to bottom, all set up to the exquisite part of size and mutually support accurately through propping the pivot stop gear 4 and pivot stop gear 3 to difficult noise and damage are difficult for producing, and the turned angle that can accurate control action bars 2 and then ensure high-quality ground switching new trend entry 11.

Referring to fig. 3 and 5, optionally, the protrusion 321 further has a first inclined surface 3212 opposite to the first position-limiting surface 3211, and the guide boss 41 further has a second inclined surface 412 opposite to the second position-limiting surface 411, which are provided to help the protrusion 321 move smoothly relative to the guide boss 41. Fig. 6, 7 and 11, when the operating rod 2 is in the installed state, the positioning boss 34 is aligned with the through groove 4221 and inserted into the hollow portion 421, as shown in fig. 8, the operating rod 2 is rotated in the second direction with the rotating shaft 33 as the center until the first inclined surface 3212 of the protrusion 321 contacts with the second inclined surface 412 of the guide boss 41, i.e., the operating rod 2 is in surface-to-surface sliding fit, and further the operating rod 2 is rotated in the second direction, the first inclined surface 3212 makes the elastic cantilever 32 bounce in the direction away from the guide boss 41, i.e., bounce upwards, under the action of the sliding friction force of the second inclined surface 412, and finally the operating rod 2 is further rotated in the second direction, the elastic cantilever 32 resets under the action of the elastic restoring force after the first inclined surface 3212 passes through the second inclined surface 412, so that the first limiting surface 3211 and the second limiting surface 411 are opposite to each other, and thus, the second limiting surface 411 may contact with the first limiting surface 3211 to limit the position 3211 in the subsequent rotation process of the operating rod 2 to limit the position of the first limiting surface 3211 . Referring further to fig. 6 and 7 and by way of example, when the operating lever 2 is in the installed state, when a user installs the operating lever 2, the positioning boss 34 on the operating lever 2 is aligned with the through groove 4221 of the protrusion 42 provided on the damper bracket 12 and then inserted to the bottom (as shown in fig. 6 and 7), and then the operating lever 2 is rotated clockwise based on the rotating shaft 33 on the operating lever 2 until the first inclined surface 3212 of the elastic cantilever 32 on the operating lever 2 contacts the second inclined surface 412 of the guiding boss 41 provided on the damper bracket 12 (as shown in fig. 8), and then the operating lever 2 is rotated clockwise continuously, and due to the friction force of the relative movement with the second inclined surface 412, the elastic cantilever 32 on the operating lever 2 springs upward, and when the operating lever 2 is rotated clockwise continuously, the elastic cantilever 32 is separated from the guiding boss 41 and then assumes the reset state (as shown in fig. 9), therefore, by providing the structure of the elastic cantilever 32 on the operating rod 2, when the operating rod 2 is installed, the first inclined surface 3212 on the elastic cantilever 32 is clamped into the protrusion 42 through the groove 4221 under the guidance of the second inclined surface 412 of the guide boss 41, and the elastic cantilever 32 can be used for limiting the rotation angle of the operating rod 2 after being reset, so that the installation operation mode of the operating rod 2 is simple and convenient, and the installation can be completed in one step.

Preferably, when the operating rod 2 is in the detached state, the operating rod 2 is rotated around the rotating shaft 33 in the first direction until the first position-limiting surface 3211 contacts the second position-limiting surface 411, and then when the operating rod 2 is further rotated in the first direction, the protrusion 321 is lifted away from the guide boss 41 to elastically deform the elastic cantilever 32, and the operating rod 2 is further rotated in the first direction until the positioning boss 34 is aligned with the through groove 4221, and then the positioning boss 34 is taken away from the through groove 4221. Further referring to fig. 9 and by way of example, with the operating lever 2 described above in a disassembled state, when the operating rod 2 needs to be disassembled for after-sale maintenance, the handle 21 on the operating rod 2 is rotated rightwards, i.e. anticlockwise, until the first limit surface 3211 of the protrusion 321 arranged on the operating rod 2 contacts the second limit surface 411 of the guide boss 41 arranged on the air door bracket 12 (as shown in fig. 9), and then the elastic cantilever 323 on the operating rod 2 is lifted by about 2mm by a finger or a small screw tool to be in an upwards bouncing state, so that the first position-limiting surface 3211 of the protrusion 321 is entirely higher than the second position-limiting surface 411 of the guide boss 41, the handle 21 on the lever 2 then continues to rotate to the right, i.e., counterclockwise, until the positioning boss 34 on the lever 2 aligns with the through slot 4221 of the protrusion 42 provided on the damper bracket 12 and is then removed upward (as shown in fig. 6). In this way, due to the elastic deformation characteristic of the elastic cantilever 32 structure, when the operating rod 2 is disassembled, the first limiting surface 3211 is only required to be away from the second limiting surface 411 by a certain height to remove the interference of the second limiting surface 411 on the first limiting surface 3211 and limit the position, and then the protrusion 321 is rotated away from the guide boss 41 to align the positioning boss 34 with the through groove 4221 until the protrusion is taken out, so that the disassembling operation of the operating rod 2 is simple and convenient, and the disassembling is easily completed.

Referring further to fig. 3 and 5, preferably, the elastic cantilever 32, the through hole 311 and the guiding boss 41 all extend along the same arc line with the rotation shaft 33 as the center, and it should be noted that the overall extending shape of the through hole 311 is similar to the overall extending shape of the elastic cantilever 32 and has a larger size, so as to ensure that the elastic cantilever 32 can be freely and elastically deformed in the through hole 311, and ensure that the elastic cantilever 32 and the guiding boss 41 can reliably abut against each other, and further, it is preferable that a larger gap is provided at the protrusion 321 of the elastic cantilever 32 in the through hole 311, so as to facilitate the insertion of a finger or a small screwdriver tool to lift the elastic cantilever 32. The protruding block 321 is provided with a first concave surface 3213 between the first limiting surface 3211 and the first inclined surface 3212, the guiding boss 41 is provided with a second concave surface 413 between the second limiting surface 411 and the second inclined surface 412, when the first limiting surface 3211 abuts against the second limiting surface 411, the first concave surface 3213 abuts against the second concave surface 413, and the first concave surface 3213 and the second concave surface 413 which are in sliding fit with each other and abut against each other are provided, so that an avoiding space is provided so that the first limiting surface 3211 moves to be completely abutted against the second limiting surface 411, and a limiting effect is further increased, and the protruding block 321 is provided with a guiding function to reduce resistance when being bounced upwards to the guiding boss 41 when the operating rod 2 is installed.

In a further refinement, in the second direction, the first and second inclined surfaces 3212 and 412 have equal acute oblique angles. This is advantageous in that the first inclined surface 3212 and the second inclined surface 412 are closely attached to each other so as to slide smoothly relative to each other and the first inclined surface 3212 receives a uniform sliding friction force.

Referring further to fig. 3 and 5, preferably, a pair of ribs 322 are provided at the fixed end of the protrusion 321, each rib 322 extending in parallel with the extending direction of the elastic cantilever 32 and having a top surface gradually increasing toward the direction away from the protrusion 321, a convex portion 3221 is provided at the free end of each rib 322, and the second position-limiting surface 411 abuts against the convex portion 3221 to prevent the operating rod 2 from further rotating, so that, by providing a pair of ribs 322, not only is the strength of the resilient cantilever 32 enhanced to ensure reliable recovery of the resilient deformation, and when the operating lever 2 is rotated in the second direction to move the projection 321 away from the guide boss 41 until the operating lever is rotated to the second operating position, the two convex tip portions 3221 abut against the guide bosses 41, limit further rotation of the operating lever 2, thereby ensuring that the damper 22 moves accurately to close the fresh air inlet 11, that is, the two convex portions 3221 have the reinforcing and limiting functions. It should be noted that, in the present embodiment, the rotation of the operating rod 2 to the second working position is ensured by the abutting of the damper 22 with the side casing plate 131 of the volute casing 13, so the two convex portions 3221 can further improve the accuracy of the rotation to the second working position, and in addition, the limitation of the rotation angle of the operating rod 2, that is, the accurate rotation to the correct second working position, can also be achieved by the abutting of the two convex portions 3221 with the guiding protrusions 41 alone.
