[0050] Referring to FIGS. 1 to 5 , an air duct mechanism 100 provided in an embodiment of the present application includes an air duct body 10, the air duct body 10 having a main mounting position 11 and an emission mounting position 17, the main mounting position 11 being used to mount a main body 211 of an ion generator 210, and the emission mounting position 17 being used to mount an emission portion 212 of the ion generator 210. The emission mounting position 17 is located on a first surface 121 of the air duct body 10 and close to an air inlet of the air duct body 10, and the emission mounting position 17 has an assembly hole 41, and the assembly hole 41 is connected to the interior of the air duct body 10. The main mounting position 11 is located on a second surface 122 of the air duct body 10.

[0051] In one embodiment, the air duct mechanism 100 is used for an air supply device 200 (as shown in FIG. 12 and FIG. 13 ), and the air supply device 200 may be, but is not limited to, a fan, and may specifically be a tower fan. To achieve its normal function, the air supply device 200 further includes a mainboard 216, a touch panel, and a housing 217 for mounting the air duct body 10, etc. The air duct body 10 has an air supply duct 13 and an air inlet and an air outlet connected to the air supply duct 13. The surface of the air duct body 10 forming the air supply duct 13 is defined as the inner surface, and the main mounting position 11 and the emission mounting position 17 may be formed on the outer surface of the air duct body 10.

[0052] Specifically, the ion generator 210 includes a main body 211, an emitting part 212 and a wire 213. The wire 213 is used to electrically connect the main body 211 and the emitting part 212 and / or the main body 211 and the main board 216. The emitting part 212 can be a brush head. The main mounting position 11 is used to mount the main body 211 of the ion generator 210. The emitting part 212 is mounted on the emitting mounting position 17, and at least part of it is located in the air supply duct 13 through the assembly hole 41 to release plasma or negative ions into the air supply duct 13. The air duct mechanism 100 may include at least two main mounting positions 11, and one of them is used to mount the main body 211 of the plasma generator 214, and the other is used to mount the main body 211 of the negative ion generator 215.

[0053] It can be understood that the first surface 121 and the second surface 122 of the air duct body 10 are different, wherein the first surface 121 is a structural surface of the air duct body 10 for forming an air inlet, and the second surface 122 is a structural surface of the air duct body 10 close to the main board 216.

[0054] The above-mentioned air duct mechanism 100, its air duct body 10 has a main mounting position 11 and an emission mounting position 17, so that the main body 211 and the emission part 212 of the ion generator 210 can be installed separately through the two mounting positions. The main body 211 can be close to the main board 216, which is convenient for wiring between the two, and the emission part 212 can be close to the air inlet, which is convenient for it to mix ions into the air supply airflow. Among them, the emission part 212 of the ion generator 210 is arranged on the first surface 121 of the air duct body 10 forming the air inlet, and is arranged close to the air inlet. The emission part 212 can release ions into the air supply air duct 13 through the assembly hole 41 on the emission mounting position 17 connected to the air supply air duct 13, mix into the air supply airflow and blow out with the air supply airflow. The main body 211 of the ion generator 210 is not restricted by the ion release position and is additionally installed on the second surface 122 of the air duct body 10. The main board 216 and the touch panel of the air supply device 200 are also located there. The distance between the main body 211 of the ion generator 210 and the main board 216 of the air supply device 200 is greatly shortened, and the difficulty of wiring is reduced.

[0055] In some embodiments, the air duct mechanism 100 further includes a limit portion 20 and a main buckle 30. The limit portion 20 is disposed on the air duct body 10 and is located around the main installation position 11. The main buckle 30 is disposed on the air duct body 10 and is used to fix the main body 211 located at the main installation position 11.

[0056] The limiting portion 20 may include a plurality of ribs 21, all of which are arranged around the main mounting position 11 to limit the movement of the main body 211 of the ion generator 210 along the plane where the main mounting position 11 is located. The main buckle 30 can be stuck on the surface of the main body 211 of the ion generator 210 to limit the movement of the main body 211 of the ion generator 210 away from the main mounting position 11, so as to stably fix the main body 211 of the ion generator 210 to the main mounting position 11 together with the limiting portion 20. The main buckle 30 at each main mounting position 11 can be arranged in pairs or individually, and it is only necessary to achieve stable fixation of the main body 211 of the ion generator 210, which is not specifically limited here.

[0057] In this way, the ion generator 210 at the installation position is fixed by the limiting portion 20 and the main buckle 30. The installation of the ion generator 210 does not require the use of screws, the required tools and the difficulty of finding are also reduced, and the assembly efficiency of the ion generator 210 can be effectively improved.

[0058] Furthermore, the main buckle 30 has a first guide surface 31 , and the first guide surface 31 is configured to generate a guide for guiding the main body 211 of the ion generator 210 to move toward the main installation position 11 .

[0059] It can be understood that the main buckle 30 is capable of elastic deformation. When the main body 211 of the ion generator 210 abuts against the first guide surface 31 of the main buckle 30 and is pressed down toward the main installation position 11, on the one hand, the main body 211 of the ion generator 210 can move toward the main installation position 11 under the guidance of the first guide surface 31, and on the other hand, the main buckle 30 is deformed by force and recovers and clamps the main body 211 of the ion generator 210 located in the main installation position 11 when the main body 211 of the ion generator 210 is completely in the main installation position 11.

[0060] In this way, the first guide surface 31 helps the main body 211 of the ion generator 210 to find the correct position and reduces the difficulty of its assembly.

[0061] Please refer to FIGS. 6 to 11 . In some embodiments, the air duct mechanism 100 further includes a mounting bracket 40 . The mounting bracket 40 is disposed at the emission mounting position 17 and is used to mount the emission portion 212 of the ion generator 210 .

[0062] It can be understood that the air duct body 10 has at least two emission installation positions 17, one of which has an installation bracket 40 installed for installing the emission part 212 of the plasma generator 214, and the other has an installation bracket 40 installed for installing the emission part 212 of the negative ion generator 215.

[0063] In this way, the emitting portion 212 of the ion generator 210 can be disposed at the emitting mounting position 17 of the air duct body 10 through the mounting bracket 40 and obtain stable support.

[0064] In some embodiments, the air duct mechanism 100 further includes a bracket buckle 50 , which is disposed on the air duct body 10 and is used to fix the mounting bracket 40 .

[0065] In this way, the mounting bracket 40 can also be quickly installed through the bracket buckle 50 , which helps to improve the assembly efficiency of the ion generator 210 .

[0066] Specifically, the bracket buckle 50 has a second guide surface 51 , and the second guide surface 51 is configured to generate a guide for guiding the mounting bracket 40 to move toward the launch mounting position 17 .

[0067] It can be understood that the bracket buckle 50 is capable of elastic deformation. When the mounting bracket 40 abuts against the second guide surface 51 of the bracket buckle 50 and is pressed down toward the launch mounting position 17, on the one hand, the mounting bracket 40 can move toward the launch mounting position 17 under the guidance of the second guide surface 51, and on the other hand, the bracket buckle 50 is deformed by the force and recovers and clamps the mounting bracket 40 located at the launch mounting position 17 when the mounting bracket 40 is completely in the launch mounting position 17.

[0068] In this way, the second guide surface 51 helps the mounting bracket 40 to find the correct position and reduces the difficulty of assembly.

[0069] Furthermore, the air duct mechanism 100 further includes a first positioning structure 60 , which is disposed on the air duct body 10 and located at the emission installation position 17 , and the mounting bracket 40 has a second positioning structure that cooperates with the positioning structure.

[0070] In this way, the first positioning structure 60 and the second positioning structure can cooperate with each other to position the assembly of the mounting bracket 40 so that it can be accurately installed in the launch mounting position 17.

[0071] Furthermore, one of the first positioning structure 60 and the second positioning structure is a positioning column, and the other is a positioning hole.

[0072] Specifically, the first positioning structure 60 is a positioning column, and the second positioning structure is a positioning hole. The positioning column can be perpendicular to the surface where the launch installation position 17 is located, so that the movement of the mounting bracket 40 along the surface where the launch installation position 17 is located is limited through the positioning hole. At the same time, the bracket buckle 50 can be stuck on the surface of the mounting bracket 40 to limit the movement of the mounting bracket 40 away from the launch installation position 17. When assembling the mounting bracket 40, it is only necessary to insert its positioning column into the positioning hole.

[0073] In this way, the mounting bracket 40 can be accurately positioned by inserting the positioning column into the positioning hole, and at the same time, it can also produce a limiting effect to improve the stability of its installation.

[0074] It can be understood that in some other embodiments, the first positioning structure 60 and the second positioning structure can also be positioning grooves, positioning protrusions, etc., which are not specifically limited here.

[0075] In some embodiments, the air duct body 10 further has a wire clamping structure 15 , which is disposed on the wiring path of the wire 213 of the ion generator 210 and is used to clamp the wire 213 of the ion generator 210 .

[0076] Specifically, the wire-holding structure 15 is located between the main mounting position 11 and the transmitting mounting position 17 and / or between the main mounting position 11 and the main board 216, and is located on the routing path of the wire 213, so as to constrain and fix the wire 213. There may be multiple wire-holding structures 15, and they are arranged in sequence along the routing path of the wire 213. The wire-holding structure 15 may be, but is not limited to, a hook, a slot, etc.

[0077] Thus, when installing the ion generator 210 , the wire 213 can be inserted into the wire-holding structure 15 and be constrained and fixed by the wire-holding structure 15 , thereby improving the stability of the electrical connection between the main body 211 and the emitting part 212 and / or the main body 211 and the main board 216 .

[0078] Please refer to FIG. 12 and FIG. 13 . The present application also provides an air supply device 200, including the above-mentioned air duct mechanism 100. It can be understood that in order to realize its normal function, the air supply device 200 also includes an ion generator 210, a main board 216, a housing 217, a wind wheel 220, etc. The wind wheel 220 is arranged in the air supply duct 13 and is used to drive the air flow to form an outward air supply. Among them, the wind wheel 220 can be but not limited to a cross-flow wind wheel 220, and the air supply device 200 can be but not limited to a fan, an air conditioner, an air purifier, etc., which are not specifically limited here.

[0079] Furthermore, the air supply device 200 also includes a mainboard 216 and a casing 217. The air duct mechanism is disposed in the casing 217, and the casing 217 also has a mainboard mounting position. The mainboard mounting position is located upwardly toward the second surface 122, and the mainboard 216 is disposed in the mainboard mounting position.

[0080] In this way, the main board 216 can be stably mounted to the housing 217 and is located close to the main mounting position 11 , which facilitates wiring between it and the main body 211 of the ion generator 210 .

[0081] Specifically, the air supply device 200 is a tower fan, the air supply duct 13 of the duct body 10 is a cross-flow duct, the first surface 121 is the side surface of the duct body 10, the second surface 122 is the end surface of the duct body 10, and the mainboard installation position is at the internal top of the casing 217.

[0082] Furthermore, the main installation position 11 includes a first installation position 111 and a second installation position 112 , and the ion generator 210 includes a plasma generator 214 and a negative ion generator 215 , the plasma generator 214 is installed at the first installation position 111 , and the negative ion generator 215 is installed at the second installation position 112 .

[0083] It can be understood that the shapes of the first installation position 111 and the second installation position 112 are adapted to the ion generator 210 to be installed thereon, and the number and shape of the main buckles 30 and the limiting portions 20 provided therein can be the same or different.

[0084] In this way, the air supply device 200 can realize the plasma function through the plasma generator 214, which has the effect of sterilization and disinfection, and can also realize the negative ion function through the negative ion generator 215, making the air supply fresher.

[0085] The air supply device 200 comprises an air duct body 10, a plasma generator 214, a negative ion generator 215, a limiter 20, a main buckle 30, a bracket buckle 50, a mounting bracket 40, etc. The air duct body 10 has a first mounting position 111, a second mounting position 112 and an emission mounting position 17. The first mounting position 111 and the second mounting position 112 are provided with a limiter 20 and a main buckle 30 around the periphery, and the bracket buckle 50 is provided around the emission mounting position 17.
