Description

Technical Field

[0001] The present application relates to the field of household electrical appliances, and in particular to an oscillating head assembly and a fan. Background Art

[0002] A related proposal proposes a fan with a humidification function. This fan uses an atomizer to generate water mist to achieve humidification. However, in this fan, the atomizer is located near the chassis of the fan's column tube, meaning that the atomizer is placed in the static part of the fan. The mist outlet is generally located on the fan's head. This requires that the atomizer piping connecting the atomizer and the mist outlet be connected from static to dynamic.

[0003] Therefore, how to achieve the connection of the atomization pipeline from static to dynamic has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to at least solve the problem in the prior art or related art of how to realize the connection of the atomization pipeline of the fan from static to dynamic.

[0005] Therefore, one object of the present invention is to provide a shaking head assembly.

[0006] Therefore, another object of the present invention is to provide a fan.

[0007] To achieve the above-mentioned purpose, the technical solution of the first aspect of the present invention provides an oscillating head assembly for a fan, the fan including a fan head, the oscillating head assembly being used to drive the fan head to rotate, the oscillating head assembly including: a rotating shaft, the rotating shaft being able to rotate, and being used to be connected to the fan head to drive the fan head to rotate; a mist passage being provided in the rotating shaft; a mist inlet joint, connected to the rotating shaft, and connected to one end of the mist passage; a mist outlet joint, connected to the rotating shaft, and connected to the other end of the mist passage; a driving member, connected to the rotating shaft, to drive the rotating shaft to rotate.

[0008] The oscillating head assembly provided in the application is used for a fan. The fan includes a fan head and an oscillating head assembly, wherein the oscillating head assembly is used to drive the fan to swing left and right. At the same time, this fan has a humidification function, which can humidify the air by spraying mist. Specifically, the oscillating head assembly includes a rotating shaft, a mist inlet joint, a mist outlet joint and a driving member. The rotating shaft is used to drive the oscillating head assembly to rotate left and right. At the same time, the interior of the rotating shaft is a hollow structure, and a mist passage can be formed through the hollow inside the rotating shaft, and the water mist that needs to humidify the air can be transported to the fan head of the fan through the interior of the rotating shaft. At the same time, in order to ensure the mist inlet and mist outlet of the rotating shaft, a mist inlet joint and a mist outlet joint are respectively provided at both ends of the rotating shaft. The mist inlet joint is used to connect the mist inlet pipe, and the mist outlet joint is used to connect the mist outlet pipe, so that the water mist can be transported to the fan head along the mist inlet pipe, the mist inlet joint, the rotating shaft, the mist outlet joint and the mist outlet pipe. This solution uses a rotating shaft to achieve the connection of the mist pipe from static to dynamic, thereby eliminating the pipeline in the overlapping part of the mist pipe and the rotating shaft, avoiding mutual interference between the mist pipe and the rotating shaft, so that the structure of the fan at the shaking head assembly can be set more compact.

[0009] In the above technical solution, optionally, the shaking head assembly also includes: a first gear, installed on the driving shaft of the driving member; a second gear, installed on the rotating shaft, capable of engaging with the first gear to rotate the rotating shaft under the drive of the first gear; wherein the second gear and the rotating shaft are a split structure, or the second gear is a gear part arranged on the rotating shaft.

[0010] In this technical solution, a gear transmission assembly is provided between the drive assembly and the rotating shaft. That is, torque is transmitted between the drive assembly and the rotating shaft via at least two gears. Compared to other transmission methods, gear transmission offers smoother transmission and a simpler structure.

[0011] The second gear and the rotating shaft can be independent parts, and the two can be fixedly connected by screws or snaps. At the same time, the second gear and the rotating shaft can also be an integrated structure, such as being integrally molded, thereby reducing the number of parts in the oscillating head assembly and making the installation connection between the second gear and the rotating shaft more secure.

[0012] In the above technical solution, optionally, the second gear includes an arc-shaped tooth portion provided on the rotating shaft, and the arc center angle corresponding to the arc-shaped tooth portion is less than 360°.

[0013] In this technical solution, the second gear is mounted on the rotating shaft and integrally injection-molded with the shaft. This means the second gear is part of the rotating shaft. Furthermore, the second gear comprises an arcuate toothed portion mounted on the rotating shaft. This means that only a portion of the second gear's wheel body is toothed, with the remainder remaining toothless. This means the gear does not form a full circle, and therefore the arc center angle corresponding to the arcuate toothed portion is less than 360°.

[0014] Optionally, the arc center angle corresponding to the arc-shaped tooth portion is related to the fan's swing angle, so that the length of the arc-shaped tooth portion can meet the fan's swing angle. The fan's swing angle is generally 90°, so the arc center angle corresponding to the arc-shaped tooth portion can be roughly set between 90° and 145°.

[0015] In the above technical solution, optionally, the oscillating head assembly further includes: a shaft sleeve, at least a portion of the rotating shaft is installed in the shaft sleeve, and the rotating shaft can rotate relative to the shaft sleeve.

[0016] In this technical solution, the oscillating assembly also includes a sleeve for mounting and protecting the rotating shaft. By providing the sleeve, friction between the rotating shaft and the fan column tube can be avoided. At the same time, the sleeve also makes it easier to route the fan cable.

[0017] In the above technical solution, optionally, at least a portion of the rotating shaft is rotatably mounted in the shaft sleeve via a wear-resistant member.

[0018] In this technical solution, by providing the wear-resistant part, the rotating shaft can be more smoothly rotated and installed in the shaft sleeve, thereby further reducing the friction between the rotating shaft and the shaft sleeve.

[0019] For example, the number of the wear-resistant parts can be one or more. Further, the wear-resistant parts can be specifically bushings or balls.

[0020] For example, the wear-resistant part is a bearing, and the number of the bearings is 2. At least a portion of the rotating shaft is rotatably mounted in the shaft sleeve via the two bearings.

[0021] In the above technical solution, optionally, the fan further includes a column tube, and the shaft sleeve is installed in the column tube.

[0022] In this technical solution, the column tube serves as the vertical support rod for the fan. The shaft sleeve is installed within the column tube. Furthermore, to ensure the proper installation of the rotating shaft within the column tube, the shaft sleeve is provided with at least two supporting portions, which facilitate the installation of the shaft sleeve within the column tube. Furthermore, a wiring channel is formed between the column tube and the shaft sleeve, through which cables connected to the fan head can be routed to the fan head.

[0023] In the above technical solution, optionally, at least one wire-holding structure is provided on the outer side wall of the sleeve, and the wire-holding structure is provided with a wire passage opening for allowing the wire to enter and exit the wire-holding structure.

[0024] In this technical solution, a wire-holding structure is provided on the outer wall of the sleeve. This structure can hold the wire in place. It also features a wire-passing opening, through which the wire can enter and exit the structure. This structure can better secure the wire and simplify wiring.

[0025] In the above technical solution, the oscillating head assembly optionally further comprises: two retaining ribs extending axially along the shaft sleeve, the two retaining ribs being disposed on the outer side wall of the shaft sleeve at intervals along the circumference of the shaft sleeve and forming a wiring channel extending axially along the shaft sleeve. Along the axial direction of the shaft sleeve, the width of the wiring channel on a side closer to the fan head is greater than the width of the wiring channel on a side farther from the fan head.

[0026] In this technical solution, in addition to the wire-holding structure, two retaining ribs are provided on the outer wall of the sleeve. These ribs form a wiring channel through which the wires can be routed. The lower end of the wiring channel is narrower, which helps secure the wires' position. The upper end of the wiring channel is wider, allowing the cables to swing with the fan head. Furthermore, the two retaining ribs better define the wires' position, preventing them from moving elsewhere.

[0027] In the above technical solution, the oscillating head assembly optionally further includes a wire retaining structure. The wire retaining structure comprises: an isolation rib located outside the sleeve and disposed on the side of the sleeve closest to the fan head, which, together with the sleeve, forms a wire retaining channel for accommodating the wires. The isolation rib is provided with a wire passage opening, and two retaining ribs are located on the side of the isolation rib away from the fan head.

[0028] In this technical solution, the isolation ribs and the sleeve form a wire-holding channel. The width of this channel is relatively large, allowing the cable to swing with the fan head. At the same time, in this solution, the wiring channel surrounded by the two retaining ribs and the isolation ribs jointly limit the position of the wires. In this way, only the isolation ribs and retaining ribs need to be set outside the sleeve to quickly and easily form a wiring channel. There is no need to set additional grooves or other structures outside the sleeve, which can make the structure of the sleeve relatively simple. In addition, the isolation ribs can be used to isolate the cable from the column tube, thereby preventing contact between the column tube and the cable, thereby preventing the column tube from causing wear on the cable.

[0029] Among them, the isolation rib is also provided with a wire passing opening, which is a gap. The wire can be easily inserted into or pulled out of the wire clamping channel through the gap.

[0030] Among them, the two retaining ribs are located on the side of the isolation rib away from the fan head, that is, the two retaining ribs are located below the isolation ribs. In this way, the isolation ribs can better limit the position of the wire when the wire follows the cable swing, preventing the cable from moving to other positions.

[0031] The two support portions include a first support portion and a second support portion. The isolation ribs may be part of the first support portion. The two retaining ribs may be part of the second support portion. In the above technical solution, the rotating shaft may optionally rotate relative to the mist inlet connector, the rotating shaft may be provided with a convex rib, and the mist inlet connector may be provided with a groove, into which the convex rib is inserted. Furthermore, the groove is filled with a sealing medium.

[0032] In this technical solution, the mist inlet connector is fixedly mounted on the shaft sleeve or the column tube, making it immovable. The rotating shaft and the mist inlet connector are rotationally connected, meaning the shaft can rotate relative to the inlet connector. To ensure a seal between the two, the rotating shaft is provided with ribs, and the mist inlet connector is provided with grooves. The ribs fit into the grooves, creating a seal within the grooves.

[0033] Furthermore, the groove is filled with a sealing medium. Specifically, the sealing medium can be a high-viscosity, non-flowing grease. This structure effectively seals the mist inlet connector and the rotating shaft, thereby preventing mist leakage. The sealing medium also acts as a lubricant, preventing wear between the ribs and the inner wall of the groove, allowing the rotating shaft to rotate more smoothly relative to the mist inlet connector.

[0034] In the above technical solution, the connection between the mist outlet connector and the rotating shaft can optionally be sealed. For example, the mist outlet connector and the rotating shaft can be sealed by screws. Alternatively, the rotating shaft and the mist outlet connector can be configured as an integrated structure, such as by welding them together or by integrally injection molding them.

[0035] In the above technical solution, optionally, the driving member includes a driving motor, which can drive the rotating shaft to rotate in both forward and reverse directions, so that the fan can swing left and right.

[0036] The technical solution of the second aspect of the present invention provides a fan, including a fan head; and the oscillating head assembly provided by the technical solution of the first aspect, wherein the fan head is connected to a rotating shaft.

[0037] The fan provided by the present invention includes a fan head and an oscillating assembly. The fan head is connected to the oscillating assembly, and the oscillating assembly is used to drive the fan head to rotate left and right. Since the fan also includes the oscillating assembly provided by the technical solution of the first aspect, the fan also includes all the beneficial effects of the oscillating assembly provided by the technical solution of the first aspect, which will not be repeated here.

[0038] In the above technical solution, optionally, the fan also includes: a base; a column tube, installed on the base, and the rotating shaft is at least partially installed in the column tube; an atomizer, installed on the column tube and / or the base; a mist inlet pipeline, installed in the column tube, and connecting the atomizer generator and the mist inlet joint; a mist outlet pipeline, installed on the fan head, and connected to the mist outlet joint.

[0039] In this technical solution, the base serves as the ground support structure for the entire fan, while the column tube provides vertical support, ensuring the fan head can be installed at a certain height. The atomizer generates the water mist needed to humidify the air. The generated water mist is guided to the fan head through the mist inlet pipe, mist inlet connector, rotating shaft, mist outlet connector, and mist outlet pipe, and then discharged into the air from the fan head.

[0040] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0054] like Figures 1 to 8 As shown, an embodiment of the first aspect of the present invention provides an oscillating head assembly 100 and a fan 200 .

[0055] like Figures 1 to 6 As shown, an embodiment of the first aspect of the present invention provides an oscillating head assembly 100, which is used for a fan 200. The fan 200 includes a fan head 210. The oscillating head assembly 100 is used to drive the fan head 210 to rotate. The oscillating head assembly 100 includes: a rotating shaft 1, which can rotate and is used to be connected to the fan head 210 to drive the fan head 210 to rotate; a mist passage 12 is provided in the rotating shaft 1; a mist inlet joint 2, which is connected to the rotating shaft 1 and communicated with one end of the mist passage 12; a mist outlet joint 3, which is connected to the rotating shaft 1 and communicated with the other end of the mist passage 12; a driving member 4, which is connected to the rotating shaft 1 to drive the rotating shaft 1 to rotate.

[0056] The oscillating assembly 100 provided in this application is used in a fan 200. The fan 200 includes a fan head 210 and the oscillating assembly 100, wherein the oscillating assembly 100 is used to drive the fan 200 to swing left and right. Furthermore, the fan 200 has a humidifying function, which can humidify the air by spraying mist.

[0057] Specifically, the oscillating head assembly 100 includes a rotating shaft 1 , a mist inlet joint 2 , a mist outlet joint 3 and a driving member 4 .

[0058] The rotating shaft 1 is used to drive the oscillating assembly 100 to rotate left and right. At the same time, the interior of the rotating shaft 1 is a hollow structure, and a mist passage 12 can be formed through the hollow inside the rotating shaft 1. The water mist that needs to humidify the air can be transported to the fan head 210 of the fan 200 through the interior of the rotating shaft 1. At the same time, in order to ensure the mist inlet and mist outlet of the rotating shaft 1, a mist inlet joint 2 and a mist outlet joint 3 are respectively provided at both ends of the rotating shaft 1. The mist inlet joint 2 is used to connect the mist inlet pipe, and the mist outlet joint 3 is used to connect the mist outlet pipe, so that the water mist can be transported to the fan head 210 along the mist inlet pipe, the mist inlet joint 2, the rotating shaft 1, the mist outlet joint 3, and the mist outlet pipe. This solution realizes the connection of the mist pipe from static to dynamic with the help of the rotating shaft 1, thereby eliminating the pipeline of the overlapping part of the mist pipe and the rotating shaft 1, avoiding mutual interference between the mist pipe and the rotating shaft 1, so that the structure of the fan 200 at the oscillating assembly 100 can be set more compactly.

[0059] In the above embodiment, optionally, as Figure 3 As shown, the fan 200 further includes a connecting member 250 , and the fan head 210 is mounted on the connecting member 250 . The motor is mounted on the connecting member 250 .

[0060] In the above embodiment, optionally, as Figure 1 and Figure 4 As shown, the shaking head assembly 100 also includes: a first gear 7, installed on the driving shaft of the driving member 4; a second gear 8, installed on the rotating shaft 1, which can engage with the first gear 7 to rotate the rotating shaft 1 under the drive of the first gear 7; wherein, the second gear 8 and the rotating shaft 1 are a split structure, or the second gear 8 is a gear part arranged on the rotating shaft 1.

[0061] In this embodiment, a gear transmission assembly is provided between the drive assembly and the rotating shaft 1. That is, torque is transmitted between the drive assembly and the rotating shaft 1 via at least two gears. Compared to other transmission methods, gear transmission offers smoother transmission and a simpler structure. The second gear 8 can be a separate component from the rotating shaft 1, and the two can be fixedly connected using screws or snaps.

[0062] At the same time, the second gear 8 can also be an integrated structure with the rotating shaft 1, for example, the two can be integrally formed, so as to reduce the number of parts of the shaking head assembly 100 and make the installation connection between the second gear 8 and the rotating shaft 1 more secure.

[0063] In the above embodiment, optionally, as Figure 4 As shown, the second gear 8 is an arc-shaped tooth portion 82 provided on the rotating shaft 1 , and the arc center angle corresponding to the arc-shaped tooth portion 82 is less than 360°.

[0064] In this embodiment, the second gear 8 is disposed on the rotating shaft 1 and is integrally injection-molded with the rotating shaft 1. That is, the second gear 8 is a part of the rotating shaft 1.

[0065] Meanwhile, the second gear 8 includes an arcuate tooth portion 82 disposed on the rotating shaft 1. That is, only a portion of the wheel body of the second gear 8 is provided with teeth, while the rest of the wheel body is not provided with teeth. In other words, the gear is not provided with a full circle, and therefore, the arc center angle corresponding to the arcuate tooth portion 82 is less than 360°.

[0066] Optionally, the arc center angle corresponding to the arc-shaped tooth portion 82 is related to the swing angle of the fan 200 , so that the length of the arc-shaped tooth portion 82 can meet the swing angle of the fan 200 .

[0067] The fan 200 generally has a swing angle of 90°. Therefore, the arc center angle corresponding to the arc-shaped tooth portion 82 can be roughly set between 90° and 145°.

[0068] In the above embodiment, optionally, as Figure 1 and Figure 4 As shown, the oscillating head assembly 100 further includes a shaft sleeve 5 , in which at least a portion of the rotating shaft 1 is installed, and the rotating shaft 1 can rotate relative to the shaft sleeve 5 .

[0069] In this embodiment, the oscillating assembly 100 further includes a sleeve 5, which is used to install and protect the rotating shaft 1. By providing the sleeve 5, friction between the rotating shaft 1 and the column tube 220 of the fan 200 can be avoided. At the same time, the provision of the sleeve 5 also makes it easier to route the cables of the fan 200. Figure 1 In the figure, the arrow passing through the interior of the rotating shaft 1 represents the path of the water mist. The arrow passing between the sleeve 5 and the column tube 220 represents the routing path of the cable.

[0070] In the above embodiment, optionally, as Figure 1 and Figure 4 As shown, at least a portion of the rotating shaft 1 is rotatably mounted in the shaft sleeve 5 through a wear-resistant member 6 .

[0071] In this embodiment, by providing the wear-resistant member 6, the rotating shaft 1 can be more smoothly rotated and installed in the shaft sleeve 5. This can further reduce the friction between the rotating shaft 1 and the shaft sleeve 5.

[0072] For example, the number of the wear-resistant parts 6 can be one or more. Furthermore, the wear-resistant parts 6 can be specifically bushings or balls.

[0073] For example, the wear-resistant part 6 is a bearing, and the number of the bearings is 2. At least a portion of the rotating shaft 1 is rotatably mounted in the shaft sleeve 5 via the two bearings.

[0074] In the above embodiment, optionally, as Figure 1 As shown, the sleeve 5 includes two support portions spaced apart along the axial direction of the rotating shaft 1, as shown in FIG. Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the fan 200 further includes a column tube 220 , and the shaft sleeve 5 is used to be installed on the column tube 220 through two supporting parts.

[0075] In this embodiment, the column tube 220 is a vertical support rod of the fan 200. The sleeve 5 is installed in the column tube 220. At the same time, in order to ensure the installation of the shaft 1 in the column tube 220, at least two supporting parts are provided on the sleeve 5. The supporting part can be specifically Figure 4 The first support portion 50 and the second support portion 52 in the column. Based on the first support portion 50 and the second support portion 52, the installation of the sleeve 5 in the column tube 220 can be achieved.

[0076] Furthermore, if Figure 1 and Figure 4 As shown, a wiring channel is formed between the column tube 220 and the shaft sleeve 5, and the cables connected to the fan head 210 can be wired to the fan head 210 through the wiring channel.

[0077] In the above embodiment, optionally, as Figure 2 and Figure 4 As shown, at least one wire-holding structure 54 is provided on the outer wall of the sleeve 5 , and the wire-holding structure 54 is provided with a wire-passing opening 5422 for allowing wires to enter and exit the wire-holding structure 54 .

[0078] In this embodiment, a wire-holding structure 54 is provided on the outer wall of the sleeve 5. This structure can hold the wires in place. Furthermore, a wire-passing opening 5422 is provided on the structure 54, through which the wires can enter and exit the structure 54. This structure can better secure the wires and simplify wiring.

[0079] In the above embodiment, optionally, as Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown, the shaking head assembly 100 further includes: two retaining ribs 58, the retaining ribs 58 are arranged along the axial direction of the sleeve 5 (such as Figure 2 The two retaining ribs 58 extend along the circumference of the sleeve 5 (as shown in the direction Figure 4 The wiring channels 59 are spaced apart (in the direction shown) on the outer side wall of the sleeve 5 and enclose a wiring channel 59 extending along the axial direction of the sleeve 5. Along the axial direction of the sleeve 5, the width T1 of the wiring channel 59 on the side close to the fan head 210 is greater than the width T2 of the wiring channel 59 on the side away from the fan head 210.

[0080] In this embodiment, in addition to the wire-holding structure 54, two retaining ribs 58 are provided on the outer wall of the sleeve 5. The two retaining ribs 58 form a wiring channel 59 through which the wires can be routed. The width T2 at the lower end of the wiring channel 59 is relatively small, which can fix the position of the wires. The width T1 at the upper end of the wiring channel 59 is relatively large, allowing the cables to swing with the fan head 210. Furthermore, the two retaining ribs 58 can better define the position of the wires, preventing them from moving to other locations.

[0081] Exemplarily, the wiring channel 59 gradually increases in size from an end away from the fan head 210 to an end close to the fan head 210 along the axial direction of the shaft sleeve 5 , that is, the wiring channel 59 is in a trumpet shape that gradually expands outward from bottom to top.

[0082] In the above embodiment, optionally, as Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown, a wire retaining structure 54 is provided on the outer wall of the sleeve 5. This structure includes a separating rib 542 located outside the sleeve 5 and on the side of the sleeve 5 closest to the fan head 210. Together with the sleeve 5, this structure forms a wire retaining channel 56 for accommodating the wires. The separating rib 542 includes a wire passage 5422, and two retaining ribs 58 located on the side of the separating rib 542 away from the fan head 210.

[0083] In this embodiment, the isolation ribs 542 and the sleeve 5 form a wire-holding channel 56, which is relatively wide, allowing the cable to swing with the fan head 210. At the same time, in this solution, the wiring channel 59 surrounded by the two retaining ribs 58 and the isolation ribs 542 jointly achieve the limitation of the wire position. In this way, only the isolation ribs 542 and retaining ribs 58 need to be provided on the outside of the sleeve 5 to simply and quickly form the wiring channel 59. There is no need to provide additional structures such as the groove 22 on the outside of the sleeve 5, thereby making the structure of the sleeve 5 relatively simple. In addition, the isolation ribs 542 can be used to isolate the cable from the column tube 220, thereby preventing the column tube 220 from contacting the cable, thereby preventing the column tube 220 from causing wear on the cable.

[0084] Among them, the isolation reinforcement 542 A wire passing opening 5422 is also provided on the top. The wire passing opening 5422 is a gap through which the wire can be easily inserted into or pulled out of the wire clamping channel 56.

[0085] Among them, such as Figure 2 、 Figure 4 、 Figure 7 and Figure 8As shown, the two retaining ribs 58 are located on the side of the isolation rib 542 away from the fan head 210, that is, the two retaining ribs 58 are located below the isolation rib 542. In this way, the isolation rib 542 can better limit the position of the wire when the wire follows the cable swing, preventing the cable from moving to other positions.

[0086] in, Figure 1 and Figure 4 The arrow S1 in FIG. 1 represents the routing path of the wire.

[0087] The two support portions include a first support portion 50 and a second support portion 52. The isolation rib 542 may be a portion of the first support portion 50. The two retaining ribs 58 may be a portion of the second support portion 52.

[0088] In the above embodiment, optionally, as Figure 1 and Figure 4 As shown, the shaft 1 can rotate relative to the mist inlet connector 2. The shaft 1 is provided with a rib 14, and the mist inlet connector 2 is provided with a groove 22. The rib 14 is inserted into the groove 22. Furthermore, the groove 22 is filled with a sealing medium.

[0089] In this embodiment, the mist inlet joint 2 is fixedly mounted on the sleeve 5 or on the column tube 220, and is fixed. The rotating shaft 1 and the mist inlet joint 2 are rotatably connected, that is, the rotating shaft 1 can rotate relative to the mist inlet joint 2. At the same time, in order to ensure the seal between the two, a rib 14 is provided on the rotating shaft 1, and a groove 22 is provided on the mist inlet joint 2. At the same time, the groove 22 is filled with a sealing medium. The sealing medium can be specifically a grease with high viscosity that will not flow. This structure can well achieve the sealing between the mist inlet joint 2 and the rotating shaft 1, thereby avoiding water mist leakage. At the same time, the sealing medium can also play a lubricating role, thereby avoiding wear between the rib 14 and the inner wall of the groove 22, so that the rotating shaft 1 can rotate more smoothly relative to the mist inlet joint 2.

[0090] In the above embodiment, the connection between the mist outlet connector 3 and the rotating shaft 1 is optionally sealed. For example, the mist outlet connector 3 and the rotating shaft 1 can be sealed by screws. Alternatively, the rotating shaft 1 and the mist outlet connector 3 can be configured as an integrated structure, for example, by welding the two into an integrated structure, or by integrally injection molding the two.

[0091] In the above embodiment, the driving member 4 optionally includes a driving motor, which can drive the rotating shaft 1 to rotate in both forward and reverse directions, so that the fan 200 can swing left and right.

[0092] like Figures 1 to 6 As shown, the embodiment of the second aspect of the present invention provides a fan 200, including a fan head 210; and the oscillating head assembly 100 provided by the embodiment of the first aspect, wherein the fan head 210 is connected to the rotating shaft 1.

[0093] The fan 200 provided by the present invention includes a fan head 210 and an oscillating assembly 100. The fan head 210 is connected to the oscillating assembly 100, and the oscillating assembly 100 is used to drive the fan head 210 to rotate left and right. Since the fan 200 also includes the oscillating assembly 100 provided by the embodiment of the first aspect, the fan 200 also includes all the beneficial effects of the oscillating assembly 100 provided by the embodiment of the first aspect, and no further details are given here.

[0094] In the above embodiment, optionally, as Figures 1 to 6 As shown, the fan 200 also includes: a base 270; a column tube 220, installed on the base 270, and the rotating shaft 1 is at least partially installed in the column tube 220; an atomizer generator 260, installed on the column tube 220 and / or the base 270; a mist inlet pipeline 230, installed in the column tube 220, and connecting the atomizer generator 260 and the mist inlet connector 2; a mist outlet pipeline 240, installed on the fan head 210, and connected to the mist outlet connector 3.

[0095] In this embodiment, the base 270 serves as a ground support structure for the entire fan, and the column tube 220 serves as a vertical support structure for the entire fan 200 , which ensures that the fan head 210 can be installed at a certain height.

[0096] The atomizing generator 260 is used to generate the water mist required for humidifying the air. The water mist generated by the atomizing generator 260 can be guided to the fan head 210 through the mist inlet pipe 230, the mist inlet connector 2, the rotating shaft 1, the mist outlet connector 3 and the mist outlet pipe, and then discharged into the air from the fan head 210.

[0097] The following further introduces the oscillating head assembly 100 and the fan 200 in the present application in conjunction with a specific embodiment.

[0098] Normally, the left and right shaking mechanism of the fan 200 also needs to provide additional functions to ensure that the live wires can be connected from the stationary part to the shaking head part. With the increase in the functions of the fan 200, the emergence of the all-in-one fan 200 connects the stationary part of the fan 200 to the shaking part. More and more wires are passed through, and even need to pass through the trachea and water pipes. For a fan 200 that provides a humidification function, its atomizing generator 260 is arranged at the stationary part of the fan 200, and the mist outlet part is arranged on the head of the fan 200. The atomizing pipeline and the connecting wires must pass through the left and right shaking mechanisms.

[0099] The present application is used to solve the problem of achieving the fan shaking about 200 and connecting the atomization pipeline and the connecting wire from static to dynamic.

[0100] Wherein, the fan 200, such as Figures 1 to 4As shown, a rotating shaft 1 and a sleeve 5 are provided. Both are of a certain length, with wear-resistant parts 6 fitting at both ends. The rotating shaft 1 is fastened to the head portion, while the sleeve 5 is fastened to the body portion. The rotating shaft 1 is hollow and is used to pass aerosol. The sleeve 5 is located outside the rotating shaft 1 and is placed within the fan 200 column tube 220. A passage is provided between the sleeve 5 and the fan 200 column tube 220 for the passage of wires. The oscillating mechanism is equipped with mist connectors at the top and bottom, and the upper mist pipe fits over the connectors with an interference fit, providing a seal.

[0101] The misting joint rotates relative to the rotating shaft 1. A circular ring is inserted into the central groove 22 between the two circular rings. High-viscosity, non-fluid grease is added to the groove 22 to provide a seal. Because the fan 200 can swing around at approximately 90°, a large gear is provided on the sleeve 5 (the gear does not need to be a full circle, just enough to achieve a 90° swing). A left-right swing motor is provided on the fan head 210, and a small gear is provided on the motor shaft. The motor shaft rotates forward and backward to achieve the swing.

[0102] Specifically, the shaking mechanism includes a shaking motor, a pinion, a rotating shaft 1, a sleeve 5, a lower mist joint, a lower bearing, an upper bearing, and an upper mist joint. The lower mist joint is connected to the lower mist pipe, and the upper mist joint is connected to the upper mist pipe to form an internal pipeline for passing aerosol. There are annular ribs on the rotating shaft 1, and double annular ribs (i.e., convex ribs 14) on the lower mist joint. The annular ribs are inserted into the grooves 22 formed inside the double annular ribs. The grooves 22 inside the double annular ribs are filled with high-viscosity grease, which plays a sealing role. The rotating shaft 1 is installed inside the sleeve 5, and the two can rotate relative to each other. The rotating shaft 1 and the sleeve 5 are connected by the upper bearing and the lower bearing, so that the rotating shaft 1 can rotate smoothly relative to the sleeve 5. The sleeve 5 is provided with a wiring harness channel. The upper part of the wiring harness channel is wide. When rotating, the wiring harness can swing in it. In order to avoid friction between the wiring harness and the inner surface of the column tube 220 when swinging, the sleeve 5 is also provided with an isolation rib 542; the lower part is narrow, and the wiring harness can be fixed in one position. There is a large gear (second gear 8) on the rotating shaft 1, and the rotating shaft 1 and the large gear are integrated. The large gear does not have to be a full circle, as long as it meets the shaking angle requirements. Three screw columns can be connected to the head part of the fan 200. An upper cylindrical surface (the side of the first support part 50) and a lower cylindrical surface (the side of the second support part 52) ​​are provided on the sleeve 5, and both are connected to the lower part of the fan 200. The shaking motor is installed on the upper connecting part 250. The entire shaking assembly 100 is installed on the column tube 220 through the upper cylindrical surface and the lower cylindrical surface on the sleeve 5.

[0103] This solution places the oscillation motors at a certain distance from the center of the left and right oscillation shafts 1, making the shaft 1 hollow and facilitating the installation of a gas path. In the absence of gas flow, a second channel can be provided on the outer edge of the oscillation mechanism to pass the wiring harness. This dual-channel setup greatly expands the application scenarios of the oscillation mechanism.
