At the same time, due to the snap connection between the quick-release unit 32 and the docking unit 21, the stability of the connection between the filter body 3 and the intake pipe joint 2 is also ensured, thereby avoiding setting the connection relationship between the filter body 3 and the intake pipe joint 2 too tightly, which makes it difficult to install and disassemble, and ensuring the convenience of assembly and disassembly.

[0033] like Figure 2 As shown, the quick-release unit 32 is arranged on the inner side of the connecting portion 31, the docking unit 21 is arranged on the outer side of the intake pipe joint 2, and the connecting portion 31 is sleeved on the outer side of the intake pipe joint 2. During the disassembly process, the filter body 3 is the component to be disassembled and assembled, and the filter body 3 is arranged and sleeved on the outer side of the intake pipe joint 2, thereby increasing the convenience of disassembly and assembly of the filter body 3.

[0034] 3. The quick-release unit 32 is a protruding block 321 provided on the connecting portion 31, and the docking unit 21 is a connecting groove 211 provided on the intake pipe connector 2. The protruding block 321 can slide within the connecting groove 211 and engage with the connecting groove 211.

When the connecting portion 31 and the intake pipe joint 2 are connected, the protrusion 321 passes through the opening portion 213 and enters the chute portion 212. The connecting groove 211 includes a chute portion 212 and an opening portion 213. The protrusion 321 can slide relatively on the chute portion 212 to adapt to the rotating sleeve connection between the filter body 3 and the intake pipe joint 2. The opening portion 213 is connected to the chute portion 212, which facilitates the protrusion 321 to enter the chute portion 212 and facilitates the alignment of the filter body 3 and the intake pipe joint 2.

[0036] like Figure 2 As shown, there are multiple quick-release units 32 and multiple docking units 21. Providing multiple docking quick-release units 32 and multiple docking units 21 can ensure the stability of the connection and enhance the connection strength.

[0037] like Figure 2 As shown, an annular plate 324 is provided on the side of the connecting portion 31 away from the intake pipe connector 2, and a limit plate 218 is provided on the intake pipe connector 2. When the connecting portion 31 is sleeved onto the intake pipe connector 2, the connecting portion 31 abuts against the limit plate 218.

[0038] The assembly and operation of the quick-release air intake filter structure in this embodiment are as follows: In this embodiment, the air intake pipe body 1 is connected to a filter body 3, wherein the filter body 3 is a truncated cone-shaped structure. Furthermore, the air intake pipe body 1 includes an air intake pipe joint 2, wherein the air intake joint is connected to the filter body 3. In this embodiment, the air intake joint and the filter body 3 are connected in a detachable manner. Furthermore, in this embodiment, the air intake joint and the filter body 3 both include a circular tube structure. The filter body 3 is provided with a connecting portion 31, wherein the connecting portion 31 is sleeved with the air intake pipe joint 2. In this embodiment, the diameter of the connecting portion 31 is larger than the diameter of the pipe joint, and the connecting portion 31 is sleeved on the outside of the air intake pipe joint 2.

[0039] Furthermore, in this embodiment, an annular vertical plate 324 is provided on the connecting portion 31, wherein the annular vertical plate 324 is provided on the side of the connecting portion 31 away from the intake pipe joint 2. The annular vertical plate 324 can provide a force point for the staff during the installation and removal of the filter body 3, and can improve the structural strength of the filter body 3, thereby avoiding deformation of the filter body 3 during the installation and removal process. During the disassembly process, since the annular vertical plate 324 is provided on the side of the connecting portion 31 away from the intake pipe joint 2, and the annular vertical plate 324 presents a vertical plate structure, that is, the annular vertical plate 324 protrudes toward the outside relative to the connecting portion 31, when force is applied on the side away from the intake pipe joint 2, the filter body 3 can be driven to be disassembled, so that during the rotational disassembly process, the staff's fingers can always be limited on the connecting portion 31, thereby making installation and disassembly easier.

[0040] Furthermore, in this embodiment, a limiting plate 218 is provided on the intake pipe joint 2, wherein the limiting plate 218 is provided on the side of the intake pipe joint 2 away from the filter body 3. Furthermore, the limiting plate 218 is also protruded toward the outside compared to the intake pipe joint 2. Since in this embodiment, the size of the connecting portion 31 is larger than that of the intake pipe joint 2, the connecting portion 31 is sleeved on the outside of the intake pipe joint 2. Therefore, during the connection process, the connecting portion 31 is sleeved on the intake pipe joint 2 and moves toward the side of the limiting plate 218. The limiting plate 218 can provide a limiting constraint effect for the connecting portion 31, thereby preventing the connecting portion 31 from moving beyond the limit, resulting in stress deformation of the docking unit 21 and the quick-release unit 32. Since the limiting plate 218 is arranged in a ring, the structural strength of the intake pipe joint 2 can also be guaranteed.

[0041] Furthermore, in this embodiment, the quick-release unit 32 provided on the connecting portion 31 is a protruding block 321, and the docking unit 21 on the intake pipe joint 2 is a connecting groove 211, wherein the protruding block 321 is snap-fitted and connected to the connecting groove 211, thereby ensuring a stable connection between the intake pipe joint 2 and the filter body 3, wherein the processing complexity of the connecting groove 211 is much higher than the setting of the protruding block 321 in terms of processing difficulty, and in terms of stability, the structural strength and stability of the connecting groove 211 are due to the protruding block 321, so the connecting groove 211 is provided on the intake pipe joint 2, and the protruding block 321 is provided on the filter body 3, thereby ensuring the structural stability of the intake pipe joint 2, and the filter body 3 is used as a replacement part, and the protruding block 321 is provided on the filter body 3 to ensure the cost of the filter body 3.

[0042] Furthermore, in this embodiment, the connection groove 211 provided on the intake pipe joint 2 is divided into a chute portion 212 and an opening portion 213, wherein the opening portion 213 is connected to the chute portion 212, and the opening portion 213 is provided close to one side of the filter body 3, and the shape and size of the opening portion 213 are the same as the shape and size of the protrusion 321, or the shape and size of the opening portion 213 are larger than the protrusion 321, so that the protrusion 321 can enter the chute portion 212 through the opening portion 213, and the protrusion 321 can The connecting portion 31 and the air intake pipe joint 2 slide relative to each other on the sliding groove portion 212. Since both the connecting portion 31 and the air intake pipe joint 2 are circular tubular structures, the movement of the connecting portion 31 relative to the air intake pipe joint 2 is rotational, and the protruding block 321 moves in a circular motion. When the protruding block 321 completes its movement along the direction of the sliding groove portion 212, the protruding block 321 is offset from the opening portion 213. Therefore, it is possible to ensure that the protruding block 321 does not fall out of the opening portion 213, thereby ensuring the stability of the connection between the filter body 3 and the air intake pipe joint 2.

[0043] Furthermore, in this embodiment, a sealing ring is provided between the connecting portion 31 and the intake pipe joint 2 to ensure the sealing of the filter body 3 on the intake pipe joint 2. At the same time, the provision of the sealing ring can further improve the connection tightness between the filter body 3 and the intake pipe joint 2.

The protruding block 321 can slide on the sliding portion 214, and the protruding block 321 snaps into the snap-fit ​​groove 215. The snap-fit ​​groove 215 is provided at the end of the sliding portion 214, and the snap-fit ​​connection with the protruding block 321 is achieved through the snap-fit ​​connection of the snap-fit ​​groove 215, thereby ensuring the stability of the connection.

[0046] A step 216 is formed between the engagement groove 215 and the sliding portion 214. The step 216 is recessed downwardly on the side adjacent to the engagement groove 215. The step 216 is provided between the engagement groove 215 and the sliding portion 214 to create a height difference between the engagement groove 215 and the sliding portion 214. Furthermore, the step 216 is recessed downwardly on the side adjacent to the engagement groove 215, thereby enabling the protrusion 321 to move smoothly and easily from the sliding portion 214 into the engagement groove 215. However, the protrusion 321 is constrained when it moves in the opposite direction within the engagement groove 215, thereby ensuring the stability of the connection.

[0047] The engaging groove 215 is provided with a limiting surface 217. When the protrusion 321 is engaged with the engaging groove 215, the limiting surface 217 abuts against the side surface of the protrusion. The limiting surface 217 provided on the engaging groove 215 can abut against the side surface of the protrusion 321, thereby ensuring a limiting effect on the movement of the protrusion 321. At the same time, the abutment with the protrusion 321 can improve the connection stability of the protrusion 321 within the engaging groove 215.

[0048] like Figure 6 As shown, the raised block 321 includes an abutting top plane 322, with a plurality of oblique guide side surfaces 323 disposed on the sides of the abutting top plane 322. The raised block 321 is formed by combining the multiple oblique guide side surfaces 323 disposed on the sides and the abutting top plane 322 at the top, forming a ridge structure that is smaller at the top and larger at the bottom, thereby ensuring the structural strength of the raised block 321 and preventing deformation and distortion during the disassembly and engagement process.

[0049] The assembly and operation of the quick-release air intake filter structure in this embodiment are as follows: In this embodiment, a filter body 3 is connected to the intake pipe body 1, wherein the filter body 3 is a truncated cone-shaped structure. Furthermore, the intake pipe body 1 includes an intake pipe joint 2, wherein the intake joint is connected to the filter body 3. In this embodiment, the intake joint and the filter body 3 are connected in a detachable manner. Furthermore, in this embodiment, the intake joint and the filter body 3 both include circular tube structures. The filter body 3 is provided with a connecting portion 31, wherein the connecting portion 31 is sleeved with the intake pipe joint 2. In this embodiment, the diameter of the connecting portion 31 is larger than the diameter of the pipe joint, and the connecting portion 31 is sleeved on the outside of the intake pipe joint 2.

[0050] Furthermore, in this embodiment, an annular vertical plate 324 is provided on the connecting portion 31, wherein the annular vertical plate 324 is provided on the side of the connecting portion 31 away from the intake pipe joint 2. The annular vertical plate 324 can provide a force point for the staff during the installation and removal of the filter body 3, and can improve the structural strength of the filter body 3, thereby avoiding deformation of the filter body 3 during the installation and removal process. During the disassembly process, since the annular vertical plate 324 is provided on the side of the connecting portion 31 away from the intake pipe joint 2, and the annular vertical plate 324 presents a vertical plate structure, that is, the annular vertical plate 324 protrudes toward the outside relative to the connecting portion 31, when force is applied on the side away from the intake pipe joint 2, the filter body 3 can be driven to be disassembled, so that during the rotational disassembly process, the staff's fingers can always be limited on the connecting portion 31, thereby making installation and disassembly easier.

[0051] Furthermore, in this embodiment, a limit plate 218 is provided on the intake pipe joint 2, wherein the limit plate 218 is provided on the side of the intake pipe joint 2 away from the filter body 3. Furthermore, the limit plate 218 is also protruded outward compared to the intake pipe joint 2. Since in this embodiment, the size of the connecting portion 31 is larger than that of the intake pipe joint 2, the connecting portion 31 is sleeved on the outside of the intake pipe joint 2. Therefore, during the connection process, the connecting portion 31 is sleeved on the intake pipe joint 2 and moves toward the side of the limit plate 218. The limit plate 218 can provide a limiting constraint effect for the connecting portion 31, thereby preventing the connecting portion 31 from moving beyond the limit, causing the docking unit 21 and the quick-release unit 32 to be deformed by force. Since the limit plate 218 is arranged in a ring, the structural strength of the intake pipe joint 2 can also be guaranteed.

[0052] Furthermore, in this embodiment, the quick-release unit 32 provided on the connecting portion 31 is a protruding block 321, and the docking unit 21 on the intake pipe joint 2 is a connecting groove 211, wherein the protruding block 321 is snap-fitted and connected to the connecting groove 211, thereby ensuring a stable connection between the intake pipe joint 2 and the filter body 3, wherein the processing complexity of the connecting groove 211 is much higher than the setting of the protruding block 321 in terms of processing difficulty, and in terms of stability, the structural strength and stability of the connecting groove 211 are due to the protruding block 321, so the connecting groove 211 is provided on the intake pipe joint 2, and the protruding block 321 is provided on the filter body 3, thereby ensuring the structural stability of the intake pipe joint 2, and the filter body 3 is used as a replacement part, and the protruding block 321 is provided on the filter body 3 to ensure the cost of the filter body 3.

[0053] Furthermore, in this embodiment, the connection groove 211 provided on the intake pipe joint 2 is divided into a chute portion 212 and an opening portion 213, wherein the opening portion 213 is connected to the chute portion 212, and the opening portion 213 is provided close to one side of the filter body 3, and the shape and size of the opening portion 213 are the same as the shape and size of the protrusion 321, or the shape and size of the opening portion 213 are larger than the protrusion 321, so that the protrusion 321 can enter the chute portion 212 through the opening portion 213, and the protrusion 321 can The connecting portion 31 and the air intake pipe joint 2 slide relative to each other on the sliding groove portion 212. Since both the connecting portion 31 and the air intake pipe joint 2 are circular tubular structures, the movement of the connecting portion 31 relative to the air intake pipe joint 2 is rotational, and the protruding block 321 moves in a circular motion. When the protruding block 321 completes its movement along the direction of the sliding groove portion 212, the protruding block 321 is offset from the opening portion 213. Therefore, it is possible to ensure that the protruding block 321 does not fall out of the opening portion 213, thereby ensuring the stability of the connection between the filter body 3 and the air intake pipe joint 2.

[0054] When the locking trough 215 is unlocked, the locking trough 215 is unlocked, and the locking trough 215 is unlocked.

[0055] Furthermore, in this embodiment, the raised block 321 is a prism structure, and is provided with an abutting top plane 322.

Furthermore, an inclined guide side 323 is provided on the circumference of the abutting top plane 322, wherein a plurality of inclined guide side 323 are provided, and in this embodiment, four are provided, thereby ensuring a smooth installation and guidance. At the same time, due to the large inclination of the inclined guide side 323, a structure is formed in which the raised block 321 is smaller at the top and larger at the bottom, thereby ensuring the structural strength of the raised block 321 and preventing deformation. In this embodiment, a plurality of raised blocks 321 and connecting grooves 211 are provided, thereby ensuring a uniform and stable connection.

[0056] Furthermore, in this embodiment, a sealing ring is provided between the connecting portion 31 and the intake pipe joint 2 to ensure the sealing of the filter body 3 on the intake pipe joint 2.
