Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a fan. Background Technology

[0002] One proposed solution involves a humidifying fan. This type of fan typically places a water tank on a base, with a mist outlet on top of the tank to blow out mist for humidification. However, this fan only has one mist outlet, resulting in a relatively unidirectional mist output, and the humidified air cannot diffuse quickly.

[0003] Therefore, designing a fan that can quickly diffuse fog has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to at least solve the technical problem in related solutions where the fan has only one mist outlet, the mist outlet direction is relatively singular, and the humidified air cannot be quickly diffused.

[0005] Therefore, a first aspect of the present invention provides a fan.

[0006] The fan provided by the present invention includes: a fan head assembly, including a fan blade assembly, a mesh cover, and a mist guiding channel; a mist outlet ring, installed on the mesh cover, forming a mist chamber with the mesh cover, the mist chamber and the outlet of the mist guiding channel are connected, the mist chamber is arranged along the circumference of the fan head assembly, and a plurality of mist outlet holes are arranged at intervals along the circumferential direction of the fan head assembly on the mist chamber; and a humidification component for generating mist, the outlet of the humidification component and the mist guiding channel are connected.

[0007] The fan provided by the present invention includes a fan head assembly and a mist outlet ring. The fan head assembly includes a fan blade assembly, a mesh cover, and a mist guiding channel. The fan blade assembly rotates, thereby causing airflow to form an airflow. The mesh cover is installed on the front side of the fan blade assembly to protect it, and the airflow generated by the fan blade assembly can be blown out through the mesh cover. The mist guiding channel is used to conduct mist, delivering the mist generated by the humidification component to the mesh cover. The mist outlet ring and the mesh cover constitute a mist chamber, which is annular and located on the edge of the mesh cover. After the mist generated by the humidification component is delivered to the mesh cover, it can enter the mist chamber and then be discharged through mist outlet holes arranged in various directions within the mist chamber. Because multiple mist outlet holes are arranged along the circumferential direction of the fan head assembly, the mist can be discharged in multiple directions of the fan, thereby enabling rapid diffusion and circulation of the mist, increasing the humidification range of the fan, and improving the uniformity of humidification.

[0008] The fan provided by the present invention may also have the following additional technical features:

[0009] In any of the above embodiments, optionally, the mesh cover includes: a base; an air outlet mesh cover, installed on the base, a mist outlet ring surrounding the circumference of the air outlet mesh cover and installed on the base, forming a mist chamber with the base.

[0010] In this embodiment, the mesh cover includes a base and an air outlet mesh cover. The air outlet mesh cover is configured corresponding to the fan blade assembly and is used to discharge the airflow generated by the fan blade assembly. The mist outlet ring is installed around the air outlet mesh cover, so that the mist chamber is arranged around the entire circumference of the air outlet mesh cover. This allows the fan air to blow out from the center, while the mist can be blown out from the sides of the fan. After the mist is discharged from the mist outlet, it can be further dispersed by the wind, thereby enabling the mist to travel further in the air with the help of airflow, thus making the mist more evenly distributed in the environment.

[0011] In any of the above embodiments, the fan may optionally further include a seal installed between the mist outlet ring and the base to seal the gap between the mist outlet ring and the base.

[0012] In this embodiment, by providing a seal, the gap between the fog ring and the base can be sealed to prevent fog from leaking from the connection between the two.

[0013] In any of the above embodiments, optionally, the fog ring includes: a plurality of fog guides installed on the fog ring and spaced apart along the circumferential direction of the fog chamber, and the plurality of fog guides are located on the side of the fog chamber near the fog outlet.

[0014] In this embodiment, multiple fog guides can divert the fog in the fog chamber, thereby ensuring that the amount of fog output is consistent in all directions, resulting in a more uniform distribution of fog in all directions.

[0015] In any of the above embodiments, optionally, the fog-emitting ring further includes: an inner ring; an outer ring, which is disposed around the circumference of the inner ring and along the radial direction of the inner ring, with a gap between the inner ring and the outer ring to form a fog channel, the fog outlet being formed by the outer ring and the inner ring at the ends away from the base, and the conduction area of ​​at least a portion of the fog channel gradually decreasing along the fog-emitting direction; wherein, a plurality of fog guides are installed between the inner ring and the outer ring, and the fog cavity includes a fog channel.

[0016] In this embodiment, the mist-emitting ring consists of an inner ring and an outer ring. The inner and outer rings are spaced apart to form a mist channel. The cross-sectional area of ​​the mist channel gradually decreases near the mist outlet, thereby increasing the mist discharge speed and allowing the mist to flow further. The mist outlet is formed by the outer end faces of the inner and outer rings, i.e., the end faces furthest from the base. This structure makes the mist-emitting ring relatively simple and easier to manufacture.

[0017] In any of the above embodiments, optionally, the fan head assembly further includes: a pitch bracket, including one of a first mounting shaft and a first mounting channel; the fan head assembly includes the other of the first mounting shaft and the first mounting channel, the first mounting shaft having a first fogging channel formed inside, the first mounting shaft being rotatably mounted in the first mounting channel; a second fogging channel, disposed on the pitch bracket and communicating with the first mounting channel; and a sealing assembly, disposed between the first mounting channel and the first mounting shaft to seal the gap between the first mounting channel and the first mounting shaft.

[0018] In this embodiment, the fan head assembly also includes a pitch bracket. The pitch bracket and the fan head assembly are rotatably connected via a first mounting shaft and a first mounting channel, allowing the fan to utilize the pitch bracket as a support for the fan head assembly, enabling the fan head assembly to rotate relative to the pitch bracket and achieve a pitch function. Simultaneously, a first fogging channel is formed inside the first mounting shaft and communicates with a second fogging channel provided on the pitch bracket. This allows fog entering the second fogging channel to flow directly from inside the first mounting shaft into the fan head assembly. In other words, the first mounting shaft serves both as a rotatable connection between the fan head assembly and the pitch bracket, enabling the pitch function of the fan head assembly, and as a fogging channel, allowing fog to flow into the fan head assembly. This eliminates the need for an additional fogging channel within the fan head assembly, simplifying the fan structure and reducing product costs. At the same time, this setting can guide the mist generated by the fan to the fan head assembly, and then the fan head assembly will emit the mist. This allows the direction of the fan's mist emission to be adjusted according to the fan head assembly, and also allows the mist emission position to be set relatively high, so that the mist can be distributed more evenly in the environment.

[0019] Furthermore, to prevent fog leakage from the connection between the first mounting channel and the first mounting shaft, this connection needs to be sealed. However, since the first mounting channel is stationary, while the first mounting shaft of the fan assembly rotates relative to the first mounting channel during operation, a dynamic sealing issue arises between them. Therefore, this application improves the sealing effect at the connection between the first mounting channel and the first mounting shaft by providing a sealing component, allowing the two to be connected via a sliding seal. This prevents the risk of fog leakage.

[0020] The sealing components can be mechanical seals, packing seals, or piston ring seals, etc.

[0021] In any of the above embodiments, optionally, the pitch support includes: a support body, in which a second fogging channel is provided; a second bushing, mounted on the support body, including a first stepped portion and a second stepped portion connected to each other, wherein a first channel is provided in the first stepped portion and a second channel is provided in the second stepped portion, the inner diameter of the first channel is smaller than the inner diameter of the second channel, a first mounting shaft is rotatably mounted in the second channel, the second fogging channel communicates with the first channel, the first mounting channel includes the first channel and the second channel; the first channel and the second channel form a stepped surface, a sealing component is disposed in the second channel, one end of the sealing component abuts against the stepped surface, and the other end of the sealing component abuts against the first mounting shaft.

[0022] In this embodiment, the pitch support includes a support body and a second bushing. The first stepped portion of the second bushing communicates with the second fogging channel, and the connection between the two is sealed, allowing fog flowing from the second fogging channel to enter the interior of the second bushing. That is, the sealing assembly and the second fogging channel are sealed together through the second bushing. The sealing assembly and the first mounting shaft are installed inside the second stepped portion of the second bushing. Simultaneously, the inner diameter of the first stepped portion is smaller than the inner diameter of the second stepped portion, and the connection between the first and second stepped portions forms a first stepped surface. This first stepped surface can be used as a first support surface. During installation, the first end of the sealing assembly can be abutted against the first stepped surface. The second end of the sealing assembly can be abutted against the first mounting shaft. This structure utilizes the stepped surface for the axial end face of the sealing assembly to abut, thus eliminating the need for a separate first support surface. This reduces the processing difficulty of the second bushing, thereby reducing product costs.

[0023] In any of the above embodiments, optionally, the first mounting shaft includes: a first shaft body rotatably mounted in the second channel, and a first fogging channel disposed in the first shaft body; a first bushing sleeve sleeved and mounted on the first shaft body, capable of rotating with the first shaft body; a sealing component abutting between the stepped surface and the end face of the first bushing sleeve, and / or the end of the sealing component away from the stepped surface sleeved and mounted on the first shaft body.

[0024] In this embodiment, the first mounting shaft includes a first shaft body, within which a first fogging channel is provided. To facilitate contact with the sealing assembly, a first bushing is additionally provided outside the first shaft body. The first bushing forms a contact support surface for contacting the sealing assembly. Simultaneously, to ensure the sealing effect of the sealing assembly, a portion of the sealing assembly can be fitted onto the first shaft body and contact the first bushing, thus enabling the sealing assembly to provide a double seal to the first mounting shaft.

[0025] In any of the above embodiments, optionally, a baffle portion is provided at one end of the first bushing near the first support surface, and the end face of the sealing assembly away from the first support surface abuts against the baffle portion.

[0026] In this embodiment, a dedicated baffle is provided on the first bushing to increase the contact area between the sealing assembly and the first bushing. During installation, the sealing assembly can be sealed between the first support surface and the baffle.

[0027] In any of the above embodiments, the fan may optionally include: an elastic element, sleeved and mounted outside the first bushing, and compressed and mounted between the baffle portion and the fan head assembly.

[0028] In this technical solution, the fan also includes an elastic element, which is compressed and installed between the baffle and the fan head assembly, so that the elastic element always provides an axial thrust to the first bushing, thereby ensuring that the sealing assembly and the first bushing are always in close contact, thus ensuring the sealing effect between the sealing assembly and the first bushing.

[0029] In any of the above embodiments, the baffle portion may optionally be a wear-resistant part.

[0030] In this embodiment, the baffle is made into a wear-resistant part, which can reduce the wear between the sealing assembly and the first bushing and avoid the first bushing from being damaged after long-term use, thus preventing the seal from failing.

[0031] Optionally, the first mounting shaft further includes a first wear-resistant portion. The sealing assembly includes a second wear-resistant portion, and the sealing assembly and the first mounting shaft are slidably sealed together via the first and second wear-resistant portions.

[0032] In this technical solution, the other end of the sealing assembly and the first bushing achieve a dynamic seal through a first wear-resistant part and a second wear-resistant part. The first and second wear-resistant parts have relatively smooth structures, which ensures that they can slide relative to each other while still achieving a seal.

[0033] Optionally, the first wear-resistant part is specifically disposed on the first bushing.

[0034] Optionally, one of the first wear-resistant part and the second wear-resistant part is a ceramic sheet, and the other of the first wear-resistant part and the second wear-resistant part is a graphite sheet.

[0035] In this technical solution, ceramic sheets possess high hardness and wear resistance, while graphite sheets exhibit elasticity and extensibility. Combining ceramic and graphite sheets leverages their respective advantages, thereby improving the sealing performance between the sealing assembly and the first bushing, ensuring excellent sealing performance under various operating conditions. Simultaneously, it extends the overall service life of the sealing assembly and the first bushing, preventing damage.

[0036] In any of the above embodiments, optionally, the first bushing includes a first sealing ring, which is sleeved and installed on the first shaft body, and the first sealing ring and the first shaft body are interference fit.

[0037] The first bushing also includes a first sealing ring, with an elastic element fitted around it. The first sealing ring is in a compressed installation state, so under the action of the elastic element, it tends to spring back, ensuring that the first bushing and the sealing assembly remain in tight contact at all times.

[0038] In this technical solution, the first bushing includes a first sealing ring and a first wear-resistant part, which are connected to each other as a whole. For example, the first sealing ring can be formed by injection molding. The interference fit between the first sealing ring and the first shaft body ensures the seal between the first bushing and the first shaft body, preventing mist from leaking between the first bushing and the first shaft body.

[0039] Optionally, the sealing assembly includes a second sealing ring and a second wear-resistant part, which are connected to each other as a single unit. For example, the second sealing ring can be formed by injection molding. The second sealing ring can achieve a seal between the sealing assembly and the pitch support, allowing all the mist discharged from the second misting channel to enter the sealing assembly and then enter the first mounting shaft. This ensures a seal between the second misting channel and the sealing assembly, preventing mist leakage from the connection between the second misting channel and the sealing assembly.

[0040] In any of the above embodiments, optionally, the fan head assembly includes: a third bushing, mounted on the fan head assembly, wherein one end of the second bushing near the fan head assembly is confined within the third bushing.

[0041] In this technical solution, the fan head assembly includes a third bushing, which is installed on the fan head assembly. The end of the second step portion near the fan head assembly is confined within the third bushing. In this way, the third bushing can be used to axially limit the second step portion of the second bushing, preventing the second bushing from shifting axially.

[0042] In any of the above embodiments, optionally, a first limiting rib is provided inside the third bushing, and a limiting flange is provided on the second bushing, the limiting flange being located on the side of the first limiting rib close to the fan head assembly; a first gap is provided between the limiting flange and the first limiting rib along the axial direction of the first mounting shaft, and a second gap is provided between the limiting flange and the third bushing along the radial direction.

[0043] In this technical solution, a first limiting rib is provided inside the third bushing, and a limiting flange is provided on the second step portion. The limiting flange is located between the first limiting rib and the fan head assembly. Through the cooperation of the first limiting rib and the limiting flange, one end of the second bushing is always inside the third bushing. Thus, the axial limiting of the second step portion can be achieved through the cooperation of the limiting flange and the first limiting rib, thereby preventing the second bushing from shifting axially.

[0044] Furthermore, since the limiting flange and the first limiting rib are provided with a first gap along the axial direction, and the limiting flange and the third bushing are provided with a second gap along the radial direction, the machining error of the second bushing can be effectively absorbed, ensuring flexible rotation and avoiding interference between the second bushing and the fan head assembly after the fan is assembled due to machining error or installation error.

[0045] In any of the above embodiments, optionally, the first mounting shaft is disposed on the first side of the fan head assembly, and the fan head assembly further includes a second mounting shaft disposed on the second side of the fan head assembly, with the first side and the second side of the fan head assembly being disposed opposite to each other; the pitch bracket includes a second mounting channel, and the second mounting shaft is rotatably mounted in the second mounting channel; the pitch drive assembly is mounted on the pitch bracket and connected to the second mounting shaft to drive the second mounting shaft to rotate.

[0046] In this technical solution, the fan head assembly is provided with a first mounting shaft and a second mounting shaft, which are arranged opposite to each other and rotatably connected to the pitch bracket. The pitch bracket is provided with a second mounting channel that mates with the second mounting shaft, and a fourth bushing is provided between the second mounting shaft and the second mounting channel to reduce wear, corrosion, and scratches on the shaft during rotation. Simultaneously, the pitch bracket is also provided with a pitch drive assembly, which is connected to the second mounting shaft to drive the second mounting shaft to rotate, thereby driving the fan head assembly to rotate, thus realizing the pitch function of the fan head assembly.

[0047] Optionally, in the above technical solution, the second mounting shaft is a hollow shaft, which is used for the passage of connecting wires between the pitch support and the fan head assembly.

[0048] In this technical solution, the second mounting shaft is a hollow shaft, and the connecting wires between the pitch bracket and the fan head assembly can be routed through the inside of the second mounting shaft. This makes it easy and convenient to connect the wires on the pitch bracket to the fan head assembly, which not only simplifies the fan structure but also improves the product's aesthetics.

[0049] In any of the above embodiments, optionally, the pitch drive assembly includes: a drive member mounted on a pitch support, the drive member including an output shaft; a first gear mounted on the output shaft; and a second gear mounted on a second mounting shaft and capable of meshing with the first gear; wherein the drive member is capable of driving the second mounting shaft to rotate through the meshing of the first gear and the second gear.

[0050] In this technical solution, the driving force of the driving component is transmitted to the second mounting shaft through gear transmission. This makes the axis of the second mounting shaft eccentrically set with respect to the axis of the output shaft of the driving component, so that the hollow shaft of the second mounting shaft is not affected by the position of the driving component, and it is convenient to connect the wires.

[0051] In any of the above embodiments, optionally, a limiting notch is provided on the second gear, and a limiting protrusion is provided in the second mounting channel. The limiting protrusion is located within the limiting notch and can rotate within the limiting notch.

[0052] In this technical solution, by matching the limiting protrusion in the second mounting channel with the limiting notch on the second gear, the rotation angle of the second gear can be limited, thereby limiting the pitch angle of the fan head assembly, ensuring that the fan works within the effective area and improving air delivery efficiency.

[0053] In any of the above embodiments, optionally, the fan head assembly further includes: a mounting bracket, the mounting bracket including a mist outlet connector and a first mounting shaft, the interior of the mist outlet connector communicating with a first mist passage, the mist outlet connector extending along the axial direction of the fan blade assembly; the mesh cover is provided with a mist inlet hole communicating with the mist chamber, the outlet of the mist outlet connector communicating with the mist inlet hole, and the mist guiding channel including a channel composed of a second mist passage, a first mist passage, a mist outlet connector and a mist inlet hole.

[0054] In this embodiment, the fan head assembly achieves a rotatable connection and mist flow between itself and the pitch support via a mounting bracket. Specifically, the mounting bracket is equipped with a first mounting shaft for support and installation. Simultaneously, the mounting bracket also features a mist outlet connector. The mist outlet connector and the first mounting shaft are positioned at a certain angle, allowing for mist redirection. This directs the mist flow from the radial direction of the fan head assembly to the axial direction, facilitating mist output along the axial direction of the fan head assembly. Furthermore, to facilitate the connection between the mounting bracket and the mist chamber, a mist inlet hole can be provided on the mesh cover. During installation, the mist outlet connector of the mounting bracket can be aligned with the mist inlet hole and sealed between them, allowing the mist to be sealed and delivered into the mist chamber through the mist outlet connector.

[0055] In order to guide the mist into the fan head assembly, a mist guiding channel is formed on the fan head assembly. The flow path of the mist on the fan head assembly is as follows: the mist first passes through the second mist channel, then enters the first mist channel, then enters the mist outlet connector, then enters the mist inlet hole, and finally enters the mist chamber.

[0056] In any of the above embodiments, optionally, the fan further includes: a third rotating shaft, which is rotatable and connected to a pitch bracket to drive the fan head assembly to rotate via the pitch bracket; a third mist inlet connector, which is connected to the third rotating shaft and communicates with the end of the third mist inlet connector away from the fan head assembly; the third rotating shaft is rotatable relative to the mist inlet connector; the third rotating shaft is provided with a rib, and the mist inlet connector is provided with a groove; the rib is inserted into the groove, and the groove is filled with a sealing medium; a second mist inlet connector, which is connected to the third rotating shaft at the end away from the first mounting channel and communicates with the other end of the third mist inlet connector; a mist inlet channel, which connects the mist inlet connector and the outlet of the humidification assembly; and a second drive assembly, which is connected to the third rotating shaft to drive the third rotating shaft to rotate.

[0057] In this embodiment, the fan includes a third rotating shaft, a mist inlet connector, and a second drive assembly. Driven by the second drive assembly, the third rotating shaft rotates the fan head assembly left and right, thus achieving left-right oscillation airflow. Simultaneously, the third rotating shaft has a hollow interior, forming a third mist-passing channel. Water mist requiring humidification can be transported to the fan head assembly through the interior of the third rotating shaft. Furthermore, to ensure mist inlet and outlet on the third rotating shaft, a mist inlet connector and a second mist-passing channel are respectively provided at both ends of the third rotating shaft. The mist inlet connector connects to the humidification assembly via the mist inlet channel, and the second mist-passing channel connects the mist chamber and the third mist-passing channel. This allows water mist to be transported to the fan head assembly along the mist inlet channel, mist inlet connector, third rotating shaft, and second mist-passing channel. This design, by utilizing the third rotating shaft, achieves a connection from static to dynamic for the mist pipe, eliminating the overlapping portion of the pipe between the mist pipe and the third rotating shaft, avoiding mutual interference between the mist pipe and the third rotating shaft. This allows for a more compact design of the fan structure at the oscillation assembly.

[0058] In this embodiment, the mist inlet connector is fixedly mounted on the fifth bushing or the column tube, remaining stationary. The third rotating shaft and the mist inlet connector are rotatably connected, meaning the third rotating shaft can rotate relative to the mist inlet connector. To ensure a seal between the two, the third rotating shaft has raised ribs, and the mist inlet connector has grooves filled with a sealing medium. The sealing medium can specifically be a high-viscosity, non-flowing grease. This structure effectively seals the mist inlet connector and the third rotating shaft, preventing water mist leakage. Simultaneously, the sealing medium also acts as a lubricant, preventing wear between the raised ribs and the inner walls of the grooves, allowing for smoother rotation of the third rotating shaft relative to the mist inlet connector.

[0059] The second drive assembly includes a second drive member; a first gear mounted on the drive shaft of the second drive assembly; and a second gear mounted on a third rotating shaft, capable of meshing with the first gear to rotate the third rotating shaft under the drive of the first gear. The second gear and the third rotating shaft are separate structures, or the second gear is a gear portion mounted on the third rotating shaft.

[0060] In this embodiment, a gear transmission assembly is provided between the second driving member and the third rotating shaft. That is, torque is transmitted between the second driving member and the third rotating shaft through at least two gears. Compared with other transmission methods, gear transmission is smoother and has a simpler structure.

[0061] The second gear and the third shaft can be independent parts, and can be fixedly connected by screws or clips. Alternatively, the second gear and the third shaft can be an integral structure, such as being molded as a single piece, which can reduce the number of parts in the oscillation assembly and make the installation and connection between the second gear and the third shaft more secure.

[0062] In any of the above embodiments, optionally, the fan further includes: a fifth bushing, at least a portion of the third rotating shaft is installed inside the fifth bushing, and the third rotating shaft is rotatable relative to the fifth bushing; at least a portion of the third rotating shaft is rotatably installed inside the fifth bushing via a wear-resistant component; a wire-clamping structure is provided on the outer wall of the fifth bushing, and the wire-clamping structure is provided with a wire passage for allowing wires to enter and exit the wire-clamping structure.

[0063] In this embodiment, the fan also includes a fifth bushing, which is used to mount and protect the third rotating shaft. By providing the fifth bushing, friction between the third rotating shaft and the fan's column tube can be avoided. Simultaneously, the fifth bushing also facilitates the routing of the fan's cable. A cable-holding structure is formed on the outer wall of the fifth bushing. This cable routing channel allows the cable to be fixed, and this routing method secures the cable outside the fifth bushing, preventing interference between the cable and the third rotating shaft.

[0064] In any of the above embodiments, optionally, the fifth bushing includes: two baffles extending along the axial direction of the fifth bushing, the two baffles being spaced apart circumferentially on the outer side wall of the fifth bushing and forming a wiring channel extending along the axial direction of the fifth bushing; along the axial direction of the fifth bushing, the width of the wiring channel on the side closer to the fan head assembly is greater than the width of the wiring channel on the side farther from the fan head assembly.

[0065] In this embodiment, in addition to the wire-clamping structure, two baffles are also provided on the outer wall of the fifth bushing. These two baffles form a wiring channel through which the wire can be routed. The lower end of the wiring channel is narrower to secure the wire's position, while the upper end is wider, allowing the cable to swing with the fan head assembly. Simultaneously, the two baffles better limit the wire's position, preventing it from moving to other locations.

[0066] In any of the above embodiments, optionally, the fifth bushing includes a wire-clamping structure. The wire-clamping structure includes: an isolation rib located outside the fifth bushing and disposed on the side of the fifth bushing near the fan head assembly, forming a wire-clamping channel with the fifth bushing to accommodate the wire, the wire-clamping channel communicating with the wire passage opening; wherein, the isolation rib is provided with a wire passage opening, and two baffle ribs are located on the side of the isolation rib away from the fan head assembly.

[0067] In this technical solution, the isolation rib and the fifth bushing form a cable-holding channel. This channel is relatively wide, allowing the cable to swing with the fan head assembly. Simultaneously, this solution, with the cable routing channel enclosed by the two baffle ribs and the isolation rib together limiting the cable's movement, allows for a simple and quick cable routing channel to be formed simply by installing the isolation rib and baffle ribs outside the fifth bushing. This eliminates the need for additional structures such as grooves outside the fifth bushing, thus simplifying its structure. Furthermore, the isolation rib isolates the cable from the support tube, preventing contact and thus avoiding wear and tear on the cable.

[0068] The isolation rib is equipped with a cable passage opening, which is a notch that allows for easy insertion and removal of the cable. Two retaining ribs are located on the side of the isolation rib furthest from the fan head assembly, below the isolation rib. This design allows the isolation rib to better limit the cable's movement as it swings with the cable, preventing it from moving to other positions.

[0069] In some embodiments, the fifth bushing may optionally include two support portions spaced axially along the third shaft, the fifth bushing being used to be mounted on the column tube via the two support portions.

[0070] In this embodiment, the column tube serves as the vertical support rod for the fan. The fifth bushing is installed inside the column tube. Furthermore, to ensure the installation of the third shaft within the column tube, the fifth bushing is provided with at least two support portions, which enable the fifth bushing to be installed within the column tube.

[0071] The system comprises two supporting components: a first supporting component and a second supporting component. The insulating rib may be part of the first supporting component. The cable clip may be part of the second supporting component.

[0072] In any of the above embodiments, optionally, it further includes: a chassis; a column tube, the column tube being mounted on the chassis; wherein, the humidification component is mounted on the chassis, the mist inlet channel is disposed inside the column tube, and the third rotating shaft is rotatably mounted inside the column tube.

[0073] In this embodiment, the column tube serves as the vertical support structure for the entire fan, ensuring that the fan head assembly can be installed at a certain height. The chassis increases the fan's contact area with the ground, thereby improving the fan's installation stability. The humidification component is mounted on the chassis, allowing for a lower installation position and further enhancing the fan's stability after installation. The mist inlet channel is located inside the column tube, meaning the mist generated by the humidification component is directly delivered to the fan head assembly through the column tube, thus preventing the mist inlet tube from being exposed and improving the fan's aesthetics.

[0074] In any of the above embodiments, the fan may optionally include a single air outlet mode, a single humidification mode, and a mode combining air outlet and humidification.

[0075] In this embodiment, when the fan is in air outlet mode, the fan outputs air, and the humidification component is not working. When the fan is in humidification mode, the humidification component works, and the fan does not output air. In the combined mode, the humidification component works, and the fan outputs air. This configuration allows the fan to operate independently of either humidification or air outlet functions, or simultaneously output air and humidify, thus making the fan more versatile and better meeting different user needs.

Detailed Implementation

[0097] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0098] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0099] The following reference Figures 1 to 17 A fan is described according to some embodiments of the present invention.

[0100] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the fan provided by the present invention includes: a fan head assembly 1, including a fan blade assembly 12, a mesh cover 14, and a mist guiding channel; a mist outlet ring 2, installed on the mesh cover 14, forming a mist chamber 3 with the mesh cover 14, the mist chamber 3 being connected to the outlet of the mist guiding channel, the mist chamber 3 being arranged along the circumference of the fan head assembly 1, and a plurality of mist outlet holes 32 being spaced apart along the circumferential direction of the fan head assembly 1 on the mist chamber 3; and a humidification assembly 8, used to generate mist, the outlet of the humidification assembly 8 being connected to the mist guiding channel.

[0101] The fan provided by the present invention includes a fan head assembly 1 and a mist outlet ring 2. The fan head assembly 1 includes a fan blade assembly 12, a mesh cover 14, and a mist guiding channel. The fan blade assembly 12 rotates, thereby causing airflow to form an airflow. The mesh cover 14 is installed on the front side of the fan blade assembly 12 to protect it, and the airflow generated by the fan blade assembly 12 can be blown out through the mesh cover 14. The mist guiding channel is used to conduct mist, so as to deliver the mist generated by the humidification assembly 8 to the mesh cover 14. The mist outlet ring 2 and the mesh cover 14 constitute a mist chamber 3, which is annular and disposed on the edge of the mesh cover 14. After the mist generated by the humidification assembly 8 is delivered to the mesh cover 14, it can enter the mist chamber 3 and then be discharged through the mist outlet holes 32 arranged in various directions of the mist chamber 3. Since multiple mist outlets 32 are arranged along the circumferential direction of the fan head assembly 1, the mist can be discharged in multiple directions of the fan, which can make the mist spread and circulate quickly, thereby increasing the humidification range of the fan and improving the uniformity of fan humidification.

[0102] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, the mesh cover 14 includes: a base 142; an air outlet mesh cover 144, which is installed on the base 142; a mist outlet ring 2 is arranged around the circumference of the air outlet mesh cover 144 and installed on the base 142, forming a mist chamber 3 with the base 142.

[0103] In this embodiment, the mesh cover 14 includes a base 142 and an air outlet mesh cover 144. The air outlet mesh cover 144 is disposed corresponding to the fan blade assembly 12 and is used to discharge the airflow generated by the fan blade assembly 12. The mist outlet ring 2 is installed around the air outlet mesh cover 144, so that the mist chamber 3 is arranged around the entire circumference of the air outlet mesh cover 144. This allows the fan air to blow out from the center, while the mist can be blown out from the sides of the fan. After the mist is discharged from the mist outlet 32, it can be further dispersed by the wind, so that the mist can move further in the air with the help of airflow, thereby making the mist more evenly distributed in the environment.

[0104] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, the fan also includes a seal 7, installed between the mist outlet ring 2 and the base 142 to seal the gap between the mist outlet ring 2 and the base 142.

[0105] In this embodiment, by providing the sealing element 7, the gap between the fog ring 2 and the base 142 can be sealed, preventing fog from leaking from the connection between the two. In addition, the sealing element 7 can also be used to seal the fog ring 2 and the mesh cover 14.

[0106] In any of the above embodiments, optionally, as Figure 7 , Figure 8 and Figure 9 As shown, the fog ring 2 includes: multiple fog guides 22, which are installed on the fog ring 2 and spaced apart along the circumferential direction of the fog chamber 3, and the multiple fog guides 22 are located on the side of the fog chamber 3 near the fog outlet 32.

[0107] In this embodiment, multiple fog guides 22 can divert the fog in the fog chamber 3, thereby making the amount of fog output consistent in all directions, and thus making the fog distribution more uniform in all directions.

[0108] In any of the above embodiments, optionally, as Figure 7 , Figure 8 and Figure 9 As shown, the fog-emitting ring 2 further includes: an inner ring 24; an outer ring 26, which is arranged around the inner ring 24 in the circumference and along the radial direction of the inner ring 24. A gap is provided between the inner ring 24 and the outer ring 26 to form a fog channel. The fog outlet 32 ​​is formed by the outer ring 26 and the inner ring 24 at the end away from the base 142, and the conduction area of ​​at least part of the fog channel gradually decreases along the fog-emitting direction. Among them, a plurality of fog guide plates 22 are installed between the inner ring 24 and the outer ring 26, and the fog chamber 3 includes a fog channel.

[0109] In this embodiment, the mist outlet ring 2 consists of an inner ring 24 and an outer ring 26. The inner ring 24 and the outer ring 26 are spaced apart to form a mist channel. The cross-sectional area of ​​the mist channel gradually decreases near the mist outlet 32, thereby increasing the mist discharge speed and allowing the mist to flow further by changing the cross-section. The mist outlet 32 ​​is formed by the outer end faces of the inner and outer rings 26, i.e., the end faces away from the base 142. This structure makes the structure of the mist outlet ring 2 relatively simple, thus easier to manufacture.

[0110] In any of the above embodiments, optionally, as Figure 10 , Figure 15 and Figure 16As shown, the fan head assembly 1 further includes: a pitch bracket 42, including one of a first mounting shaft and a first mounting channel 422; the fan head assembly 1 includes the other of the first mounting shaft and the first mounting channel 422, the first mounting shaft having a first fogging channel 1842 formed inside, the first mounting shaft being rotatably mounted in the first mounting channel 422; a second fogging channel 5, disposed on the pitch bracket 42 and communicating with the first mounting channel 422; and a sealing assembly 6, disposed between the first mounting channel 422 and the first mounting shaft to seal the gap between the first mounting channel 422 and the first mounting shaft.

[0111] In this embodiment, the fan head assembly 1 also includes a pitch bracket 42. The pitch bracket 42 and the fan head assembly 1 are rotatably connected via a first mounting shaft and a first mounting channel 422, so that the fan can use the pitch bracket 42 as a support for the fan head assembly 1, allowing the fan head assembly 1 to rotate relative to the pitch bracket 42 and achieve a pitch function. Simultaneously, a first fogging channel 1842 is formed inside the first mounting shaft and communicates with a second fogging channel 5 provided on the pitch bracket 42. Thus, the fog entering the second fogging channel 5 can directly flow from inside the first mounting shaft into the fan head assembly 1. In other words, the first mounting shaft can serve both as a rotatable connector between the fan head assembly 1 and the pitch bracket 42, enabling the pitch function of the fan head assembly 1, and as a fogging channel, allowing fog to flow into the fan head assembly 1. Therefore, it is unnecessary to add an additional fogging channel to the fan head assembly 1, thereby simplifying the fan structure and reducing product costs. At the same time, this setting can guide the mist generated by the fan to the fan head assembly 1, and then the mist is discharged from the fan head assembly 1. This allows the direction of the fan's mist discharge to be adjusted according to the fan head assembly 1, and also allows the mist discharge position to be set relatively high, so that the mist can be distributed more evenly in the environment.

[0112] Furthermore, to prevent fog leakage from the connection between the first mounting channel 422 and the first mounting shaft, this connection needs to be sealed. However, since the first mounting channel 422 is stationary, while the first mounting shaft of the fan assembly 1 rotates relative to the first mounting channel 422 during operation, a dynamic sealing issue arises between them. Therefore, this application provides a sealing component 6 at the connection between the first mounting channel 422 and the first mounting shaft, enabling a sliding seal between them. This improves the sealing effect at the connection and prevents the risk of fog leakage.

[0113] Among them, the sealing component 6 can be a mechanical seal component, a packing seal component, or a piston ring seal component, etc.

[0114] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, the pitch support 42 includes: a support body 420, in which a second fogging channel 5 is provided; a second bushing 426, mounted on the support body 420, including a first stepped portion 4262 and a second stepped portion 4264 connected to each other, wherein a first channel 42622 is provided in the first stepped portion 4262, and a second channel 42642 is provided in the second stepped portion 4264, wherein the inner diameter of the first channel 42622 is smaller than the inner diameter of the second channel 42642, and a first mounting shaft is rotatably mounted in the second channel 42642, wherein the second fogging channel 5 communicates with the first channel 42622, and the first mounting channel 422 includes the first channel 42622 and the second channel 42642; the first channel 42622 and the second channel 42642 form a stepped surface 4266, and a sealing component 6 is disposed in the second channel 42642, wherein one end of the sealing component 6 abuts against the stepped surface 4266, and the other end of the sealing component 6 abuts against the first mounting shaft.

[0115] In this embodiment, the pitch support 42 includes a support body 420 and a second bushing 426. The first stepped portion 4262 of the second bushing 426 communicates with the second fogging channel 5, and the connection between the two is sealed, allowing fog flowing from the second fogging channel 5 to enter the interior of the second bushing 426. That is, the sealing component 6 and the second fogging channel 5 are sealed together through the second bushing 426. The sealing component 6 and the first mounting shaft are installed inside the second stepped portion 4264 of the second bushing 426. Simultaneously, the inner diameter of the first stepped portion 4262 is smaller than the inner diameter of the second stepped portion 4264. The connection between the first stepped portion 4262 and the second stepped portion 4264 forms a first stepped surface 4266, which can be used as a first support surface. During installation, the first end of the sealing component 6 can be abutted against the first stepped surface 4266. The second end of the sealing component 6 can be abutted against by the first mounting shaft. This structure utilizes the stepped surface 4266 for the axial end face of the sealing component 6 to abut, thus eliminating the need for an additional first support surface. This reduces the machining difficulty of the second bushing 426 and consequently lowers product costs.

[0116] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, the first mounting shaft includes: a first shaft body 184, rotatably mounted in a first mounting channel 422, and a first fogging channel 1842 disposed in the first shaft body 184; a first bushing 16, sleeved and mounted on the first shaft body 184, and rotatable with the first shaft body 184; a sealing component 6 abutting between the stepped surface 4266 and the end face of the first bushing 16, and / or the end of the sealing component 6 away from the stepped surface 4266 is sleeved and mounted on the first shaft body 184.

[0117] In this embodiment, the first mounting shaft includes a first shaft body 184, within which a first fogging channel 1842 is provided. To facilitate contact with the sealing component 6, a first bushing 16 is additionally provided outside the first shaft body 184. The first bushing 16 forms a contact support surface for contacting the sealing component 6. Simultaneously, to ensure the sealing effect of the sealing component 6, a portion of the sealing component 6 can be fitted onto the first shaft body 184 and simultaneously contact the first bushing 16, enabling the sealing component 6 to provide a double seal for the first mounting shaft.

[0118] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, a baffle portion 160 is provided at one end of the first bushing 16 near the first support surface, and the end face of the sealing assembly 6 away from the first support surface abuts against the baffle portion 160.

[0119] In this embodiment, in order to increase the contact area between the sealing assembly 6 and the first bushing 16, a special baffle portion 160 is provided on the first bushing 16. During installation, the sealing assembly 6 can be sealed and installed between the first support surface and the baffle portion 160.

[0120] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, the fan also includes: an elastic element 17, which is sleeved and installed outside the first bushing 16 and compressed and installed between the baffle portion 160 and the fan head assembly 1.

[0121] In this embodiment, the fan also includes an elastic element 17, which is compressedly installed between the baffle portion 160 and the fan head assembly 1, so that the elastic element 17 always provides an axial thrust to the first bushing 16, thereby ensuring that the sealing assembly 6 and the first bushing 16 are always in close contact, thus ensuring the sealing effect between the sealing assembly 6 and the first bushing 16.

[0122] In any of the above embodiments, the baffle portion 160 may optionally be a wear-resistant part 97.

[0123] In this embodiment, the baffle portion 160 is configured as a wear-resistant part 97, which can reduce the wear between the sealing assembly 6 and the first bushing 16 and prevent the first bushing 16 from being damaged after long-term use, thus causing the seal to fail.

[0124] Optionally, such as Figure 10 , Figure 14 and Figure 16As shown, the first mounting shaft also includes a first wear-resistant portion 162. The sealing assembly 6 includes a second wear-resistant portion 62, and the sealing assembly 6 and the first mounting shaft are slidably sealed together through the first wear-resistant portion 162 and the second wear-resistant portion 62.

[0125] In this embodiment, the other end of the sealing assembly 6 and the first bushing 16 achieve a dynamic seal through the first wear-resistant part 162 and the second wear-resistant part 62. The first wear-resistant part 162 and the second wear-resistant part 62 have relatively smooth structures, which ensures that they can slide relative to each other while still achieving a seal.

[0126] Optionally, the first wear-resistant part 162 is specifically disposed on the first bushing 16.

[0127] Optionally, one of the first wear-resistant part 162 and the second wear-resistant part 62 is a ceramic sheet, and the other of the first wear-resistant part 162 and the second wear-resistant part 62 is a graphite sheet.

[0128] In this embodiment, because ceramic sheets have high hardness and wear resistance, while graphite sheets have a certain degree of elasticity and extensibility, combining ceramic and graphite sheets can fully leverage their respective advantages, thereby improving the sealing performance between the sealing assembly 6 and the first bushing 16 and ensuring good sealing performance under different operating conditions. Simultaneously, it can also extend the overall service life of the sealing assembly 6 and the first bushing 16, preventing damage.

[0129] In any of the above embodiments, optionally, as Figure 14 As shown, the first bushing 16 includes a first sealing ring 164, which is sleeved and installed on the first shaft body 184. The first sealing ring 164 and the first shaft body 184 are interference fit.

[0130] The first bushing 16 also includes a first sealing ring 164, and an elastic element 17 is sleeved on the outside of the first sealing ring 164. The first sealing ring 164 is in a compressed installation state, so that under the action of the elastic element 17, the first sealing ring 164 has a tendency to spring back, thereby ensuring that the first bushing 16 and the sealing assembly 6 are always in close contact.

[0131] In this embodiment, the first bushing 16 includes a first sealing ring 164 and a first wear-resistant part 162, which are connected to each other as a whole. For example, the first sealing ring 164 can be formed by injection molding. The interference fit between the first sealing ring 164 and the first shaft body 184 can ensure the seal between the first bushing 16 and the first shaft body 184, and prevent mist from leaking between the first bushing 16 and the first shaft body 184.

[0132] Optionally, such as Figure 14As shown, the sealing assembly 6 includes a second sealing ring 64 and a second wear-resistant part 62, which are connected to each other as a whole. For example, the second sealing ring 64 can be formed by injection molding. The second sealing ring 64 can achieve a seal between the sealing assembly 6 and the pitch support 42, so that all the mist discharged from the second mist channel 5 can enter the sealing assembly 6, and then enter the first mounting shaft from the sealing assembly 6. This ensures the seal between the second mist channel 5 and the sealing assembly 6, and prevents the mist from leaking from the connection between the second mist channel 5 and the sealing assembly 6.

[0133] Optionally, such as Figure 14 As shown, the sealing assembly 6 is provided with a first fogging hole 66.

[0134] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, the pitch support 42 includes: a third bushing 15, which is installed on the fan head assembly 1, and a second bushing 426, one end of which is located near the fan head assembly 1, is confined within the third bushing 15.

[0135] In this embodiment, the fan head assembly 1 includes a third bushing 15, which is installed on the fan head assembly 1. The second step portion 4264 is located within the third bushing 15 at one end near the fan head assembly 1. In this way, the third bushing 15 can be used to axially limit the second step portion 4264 of the second bushing 426, thus preventing the second bushing 426 from shifting axially.

[0136] In any of the above embodiments, optionally, as Figure 10 , Figure 14 and Figure 16 As shown, a first limiting rib is provided inside the third bushing 15, and a limiting flange is provided on the second bushing 426. The limiting flange is located on the side of the first limiting rib close to the fan head assembly 1. A first gap is provided between the limiting flange and the first limiting rib along the axial direction of the first mounting shaft, and a second gap is provided between the limiting flange and the third bushing 15 along the radial direction.

[0137] In this embodiment, a first limiting rib is provided inside the third bushing 15, and a limiting flange is provided on the second step portion 4264. The limiting flange is located between the first limiting rib and the fan head assembly 1. Through the cooperation of the first limiting rib and the limiting flange, one end of the second bushing 426 is always inside the third bushing 15. Thus, the axial limiting of the second step portion 4264 can be achieved through the cooperation of the limiting flange and the first limiting rib, thereby preventing the second bushing 426 from shifting axially.

[0138] Furthermore, since the limiting flange and the first limiting rib are provided with a first gap along the axial direction, and the limiting flange and the third bushing 15 are provided with a second gap along the radial direction, the machining error of the second bushing 426 can be effectively absorbed, ensuring flexible rotation and preventing the second bushing 426 from interfering with the fan head assembly 1 after the fan is assembled due to machining error or installation error.

[0139] In any of the above embodiments, optionally, as Figure 11 As shown, the first mounting shaft is disposed on the first side of the fan head assembly 1, and the fan head assembly 1 also includes a second mounting shaft 19 disposed on the second side of the fan head assembly 1. The first side and the second side of the fan head assembly 1 are disposed opposite to each other. The pitch bracket 42 includes a second mounting channel 424, and the second mounting shaft 19 is rotatably mounted in the second mounting channel 424. The fan also includes: a fourth bushing, which is installed in the second mounting channel 424 and sleeved on the outside of the second mounting shaft 19; and a pitch drive assembly 44, which is mounted on the pitch bracket 42 and connected to the second mounting shaft 19 to drive the second mounting shaft 19 to rotate.

[0140] In this embodiment, the fan head assembly 1 is provided with a first mounting shaft and a second mounting shaft 19, which are arranged opposite to each other and rotatably connected to the pitch bracket 42. The pitch bracket 42 is provided with a second mounting channel 424 that mates with the second mounting shaft 19, and a fourth bushing is provided between the second mounting shaft 19 and the second mounting channel 424 to reduce wear, corrosion, and scratches on the shaft during rotation. Simultaneously, the pitch bracket 42 is also provided with a pitch drive assembly 44, which is connected to the second mounting shaft 19 to drive the second mounting shaft 19 to rotate, thereby driving the fan head assembly 1 to rotate, thus realizing the pitch function of the fan head assembly 1.

[0141] In the above embodiments, optionally, as shown... Figure 11 As shown, the second mounting shaft 19 is a hollow shaft, used for the passage of connecting wires between the pitch support 42 and the fan head assembly 1.

[0142] In this embodiment, the second mounting shaft 19 is a hollow shaft, and the connecting wires between the pitch bracket 42 and the fan head assembly 1 can be routed through the inside of the second mounting shaft 19. This makes it easy and convenient to connect the wires on the pitch bracket 42 to the fan head assembly 1, which not only simplifies the fan structure but also improves the product's aesthetics.

[0143] In any of the above embodiments, optionally, the pitch drive assembly 44 includes: a drive member mounted on the pitch support 42, the drive member including an output shaft; a first gear mounted on the output shaft; and a second gear mounted on a second mounting shaft 19, capable of meshing with the first gear; wherein the drive member can drive the second mounting shaft 19 to rotate through the meshing of the first gear and the second gear.

[0144] In this embodiment, the driving force of the driving component is transmitted to the second mounting shaft 19 through gear transmission. This makes the axis of the second mounting shaft 19 eccentrically set with respect to the axial direction of the output shaft of the driving component, so that the hollow shaft of the second mounting shaft 19 is not affected by the position of the driving component, which facilitates the connection of wires.

[0145] In any of the above embodiments, optionally, a limiting notch is provided on the second gear, and a limiting protrusion is provided in the second mounting channel 424. The limiting protrusion is located in the limiting notch and can rotate within the limiting notch.

[0146] In this embodiment, by engaging the limiting protrusion in the second mounting channel 424 and the limiting notch on the second gear, the rotation angle of the second gear can be limited, thereby limiting the pitch angle of the fan head assembly 1, ensuring that the fan works within the effective area and improving air delivery efficiency.

[0147] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, the fan head assembly 1 also includes: a mounting bracket 18, which includes a mist outlet connector 182 and a first mounting shaft. The interior of the mist outlet connector 182 is connected to the first mist passage channel 1842, and the mist outlet connector 182 extends along the axial direction of the fan blade assembly 12. The mesh cover 14 is provided with a mist inlet hole 146 that is connected to the mist chamber 3. The outlet of the mist outlet connector 182 is connected to the mist inlet hole 146. The mist guiding channel includes a channel formed by the second mist passage channel 5, the first mist passage channel 1842, the mist outlet connector 182, and the mist inlet hole 146.

[0148] In this embodiment, the fan head assembly 1 is rotatably connected to the pitch support 42 and allows for mist flow via the mounting bracket 18. Specifically, the mounting bracket 18 is provided with a first mounting shaft for support and installation. The mounting bracket 18 also has a mist outlet connector 182. The mist outlet connector 182 and the first mounting shaft are set at a certain angle, which allows for mist diversion, thus changing the flow of mist from the radial direction of the fan head assembly 1 to the axial direction, facilitating mist output along the axial direction of the fan head assembly 1. Furthermore, to facilitate the connection between the mounting bracket 18 and the mist chamber 3, a mist inlet hole 146 can be provided on the mesh cover 14. During installation, the mist outlet connector 182 of the mounting bracket 18 can be aligned with the mist inlet hole 146 and sealed between them, allowing mist to be sealed and delivered into the mist chamber 3 through the mist outlet connector 182.

[0149] In order to guide the mist into the fan head assembly 1, a mist guiding channel is formed on the fan head assembly 1. The flow path of the mist on the fan head assembly 1 is as follows: the mist first passes through the second mist passage 5, then enters the first mist passage 1842, then enters the mist outlet 182, then enters the mist inlet 146 from the mist outlet 182, and finally enters the mist chamber 3.

[0150] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the fan also includes: a third rotating shaft 92, which is rotatable and connected to the fan head assembly 1 via a pitch bracket 42, so as to drive the fan head assembly 1 to rotate via the pitch bracket 42; a third mist passage 924 is provided inside the third rotating shaft 92; a mist inlet connector 93, which is connected to the third rotating shaft 92 and communicates with the end of the third mist passage 924 away from the fan head assembly 1, and the third rotating shaft 92 is rotatable relative to the mist inlet connector 93; a rib 922 is provided on the third rotating shaft 92, and a groove 932 is provided on the mist inlet connector 93; the rib 922 is inserted into the groove 932, and the groove 932 is filled with a sealing medium; a second mist passage 5, the end of which is away from the first mounting channel 422 is connected to the third rotating shaft 92 and communicates with the other end of the third mist passage 924; a mist inlet channel 94, which is used to connect the mist inlet connector 93 and the outlet of the humidification assembly 8; and a second drive assembly 95, which is connected to the third rotating shaft 92 to drive the third rotating shaft 92 to rotate. The second drive assembly 95 can be specifically mounted on the pitch support 42.

[0151] In this embodiment, the fan includes a third rotating shaft 92, a mist inlet connector 93, and a second drive assembly 95. The third rotating shaft 92, driven by the second drive assembly 95, drives the fan head assembly 1 to rotate left and right, thereby achieving left-right oscillation of the fan for air delivery. Simultaneously, the third rotating shaft 92 has a hollow internal structure, forming a third mist-passing channel 924. Water mist requiring humidification can be transported to the fan head assembly 1 through the interior of the third rotating shaft 92. Furthermore, to ensure mist inlet and outlet of the third rotating shaft 92, a mist inlet connector 93 and a second mist-passing channel 5 are respectively provided at both ends of the third rotating shaft 92. The mist inlet connector 93 connects to the humidification assembly 8 via the mist inlet channel 94, and the second mist-passing channel 5 connects the mist chamber 3 and the third mist-passing channel 924, thus allowing water mist to be transported to the fan head assembly 1 along the mist inlet channel 94, the mist inlet connector 93, the third rotating shaft 92, and the second mist-passing channel 5. This solution utilizes the third rotating shaft 92 to connect the mist tube from a stationary to a moving position, thereby eliminating the overlapping part of the pipe between the mist tube and the third rotating shaft 92 and avoiding mutual interference between the mist tube and the third rotating shaft 92. This allows for a more compact design of the fan structure at the oscillation assembly.

[0152] In this embodiment, the mist inlet connector 93 is fixedly mounted on the fifth bushing 96 or on the column tube 91, and remains stationary. The third rotating shaft 92 and the mist inlet connector 93 are rotatably connected, meaning the third rotating shaft 92 can rotate relative to the mist inlet connector 93. To ensure a seal between them, the third rotating shaft 92 has a raised rib 922, and the mist inlet connector 93 has a groove 932 filled with a sealing medium. The sealing medium can specifically be a high-viscosity, non-flowing grease. This structure effectively seals the mist inlet connector 93 and the third rotating shaft 92, preventing water mist leakage. Simultaneously, the sealing medium also acts as a lubricant, preventing wear between the inner walls of the raised rib 922 and the groove 932, allowing the third rotating shaft 92 to rotate more smoothly relative to the mist inlet connector 93.

[0153] The second drive assembly 95 includes a second drive member; a first gear mounted on the drive shaft of the second drive assembly 95; and a second gear mounted on the third rotating shaft 92, capable of meshing with the first gear to rotate the third rotating shaft 92 under the drive of the first gear. The second gear and the third rotating shaft 92 are separate structures, or the second gear is a gear part disposed on the third rotating shaft 92.

[0154] In this embodiment, a gear transmission assembly is provided between the second driving member and the third rotating shaft 92. That is, torque is transmitted between the second driving member and the third rotating shaft 92 through at least two gears. Compared with other transmission methods, gear transmission is smoother and has a simpler structure.

[0155] The second gear and the third rotating shaft 92 can be independent parts, and can be fixedly connected by screws or clips. Alternatively, the second gear and the third rotating shaft 92 can be an integral structure, such as being molded as a single piece, which can reduce the number of parts in the oscillation assembly and make the installation and connection between the second gear and the third rotating shaft 92 more secure.

[0156] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the fan also includes: a fifth shaft sleeve 96, at least a portion of a third rotating shaft 92 is installed inside the fifth shaft sleeve 96, and the third rotating shaft 92 is rotatable relative to the fifth shaft sleeve 96; at least a portion of the third rotating shaft 92 is rotatably installed inside the fifth shaft sleeve 96 via a wear-resistant part 97; a wire clamping structure 962 is provided on the outer wall of the fifth shaft sleeve 96, and the wire clamping structure 962 is provided with a wire passage 96222 for allowing wires to enter and exit the wire clamping structure 962.

[0157] In this embodiment, the fan further includes a fifth bushing 96, which is used to mount and protect the third rotating shaft 92. By providing the fifth bushing 96, friction between the third rotating shaft 92 and the fan's column tube 91 can be avoided. Simultaneously, the fifth bushing 96 facilitates the routing of the fan's cable. A cable-holding structure 962 is formed on the outer wall of the fifth bushing 96. This cable routing channel 968 allows the cable to be fixed, and this routing method secures the cable outside the fifth bushing 96, preventing interference between the cable and the third rotating shaft 92.

[0158] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the fifth bushing 96 includes: two baffles 966, which extend along the axial direction of the fifth bushing 96. The two baffles 966 are spaced apart on the outer side wall of the fifth bushing 96 in the circumferential direction and form a wiring channel 968 extending along the axial direction of the fifth bushing 96. Along the axial direction of the fifth bushing 96, the width of the wiring channel 968 on the side closer to the fan head assembly 1 is greater than the width of the wiring channel 968 on the side away from the fan head assembly 1.

[0159] In this embodiment, in addition to the wire clamping structure 962, two baffles 966 are also provided on the outer wall of the fifth bushing 96. These two baffles 966 form a wiring channel 968 through which the wire can be routed. The lower end of the wiring channel 968 is narrower to secure the wire's position. The upper end of the wiring channel 968 is wider, allowing the cable to swing with the fan head assembly 1. Simultaneously, the two baffles 966 better limit the wire's position, preventing it from moving to other locations.

[0160] In any of the above embodiments, optionally, as Figure 12 , Figure 13 and Figure 17 As shown, the fifth bushing 96 includes a wire-clamping structure 962. The wire-clamping structure 962 includes: an isolation rib 9622, located outside the fifth bushing 96 and disposed on the side of the fifth bushing 96 near the fan head assembly 1, forming a wire-clamping channel 964 with the fifth bushing 96 to accommodate the wire, the wire-clamping channel 964 communicating with the wire passage 96222; wherein, the isolation rib 9622 is provided with a wire passage 96222, and two baffle ribs 966 are located on the side of the isolation rib 9622 away from the fan head assembly 1.

[0161] In this embodiment, the isolation rib 9622 and the fifth bushing 96 form a cable-holding channel 964. This channel is relatively wide, allowing the cable to swing with the fan head assembly 1. Simultaneously, in this design, the cable routing channel 968 formed by the two baffles 966 and the isolation rib 9622 together limit the movement of the wire. Thus, by simply installing the isolation rib 9622 and baffles 966 outside the fifth bushing 96, the cable routing channel 968 can be formed quickly and easily, without the need for additional structures such as the groove 932 outside the fifth bushing 96, thereby simplifying the structure of the fifth bushing 96. Furthermore, the isolation rib 9622 isolates the cable from the column tube 91, preventing contact between the column tube 91 and the cable, and thus avoiding wear caused by the column tube 91 on the cable.

[0162] The isolation rib 9622 is also provided with a wire passage opening 96222, which is a notch. Through this notch, the wire can be easily inserted into or removed from the wire clamping channel 964. The two baffles 966 are located on the side of the isolation rib 9622 away from the fan head assembly 1, that is, the two baffles 966 are located below the isolation rib 9622. In this way, the isolation rib 9622 can better limit the wire when it swings with the cable, preventing the cable from moving to other positions.

[0163] In some embodiments, optionally, such as Figure 12 and Figure 13 As shown, the fifth bushing 96 includes two support portions spaced apart along the axial direction of the third rotating shaft 92. The fifth bushing 96 is used to be installed on the column tube 91 via the two support portions.

[0164] In this embodiment, the column tube 91 serves as the vertical support rod for the fan. The fifth bushing 96 is installed inside the column tube 91. Meanwhile, to ensure the installation of the third rotating shaft 92 within the column tube 91, the fifth bushing 96 is provided with at least two support portions, which enable the installation of the fifth bushing 96 within the column tube 91.

[0165] The system comprises two supporting components: a first supporting component and a second supporting component. The isolation rib 9622 can be part of the first supporting component. The wire clip can be part of the second supporting component.

[0166] In any of the above embodiments, optionally, as Figures 1 to 4 As shown, the fan also includes: a chassis 90; a column tube 91, which is mounted on the chassis 90; wherein, the humidification component 8 is mounted on the chassis 90, the mist inlet channel 94 is disposed inside the column tube 91, and the third rotating shaft 92 is rotatably mounted inside the column tube 91.

[0167] In this embodiment, the column tube 91 serves as the vertical support structure for the entire fan, ensuring that the fan head assembly 1 can be installed at a certain height. The chassis 90 increases the fan's contact area with the ground, thereby improving the fan's installation stability. The humidification component 8 is mounted on the chassis 90, allowing for a lower installation position and further enhancing the fan's stability after installation. The mist inlet channel 94 is located within the column tube 91, meaning that the mist generated by the humidification component 8 is directly delivered to the fan head assembly 1 through the column tube 91, thus preventing the mist inlet tube from being exposed and improving the fan's aesthetics.

[0168] In any of the above embodiments, the fan may optionally include a single air outlet mode, a single humidification mode, and a mode combining air outlet and humidification.

[0169] In this embodiment, when the fan is in air outlet mode, the fan outputs air, and the humidification component 8 is not working. When the fan is in humidification mode, the humidification component 8 is working, and the fan does not output air. In the combined mode, the humidification component 8 is working, and the fan outputs air. This configuration allows the fan to operate independently of either humidification or air outlet functions, or simultaneously output air and humidify, thus making the fan more versatile and better meeting different user needs.

[0170] The fan in this application will be further described below with reference to a specific embodiment.

[0171] This embodiment designs a fan with a humidification system and a circulating air system. These two systems can be freely combined and independently controlled to achieve humidification and circulating air delivery. For example... Figure 4 As shown, the humidification system (mainly including humidification component 8) is designed in the lower half of the machine. The humidified mist is delivered to the outer casing of the circulating fan (such as the mesh cover 14) through a series of pipes and interfaces to complete the fogging effect of the whole machine. The circulating fan system and the humidification system can work separately or in combination to accelerate the diffusion of humidified mist through the circulating pipe.

[0172] The fan includes a humidification assembly consisting of a humidification module and a water tank, a mist transfer tube, a mist guide tube, a left and right oscillation assembly, a bracket for connecting the mist transfer tube, a pitch mist outlet adapter assembly, a pitch drive assembly, a motor fan blade assembly, a mist outlet, and a mist outlet of the humidification assembly.

[0173] Specific working principle, such as Figure 4 As shown, the humidification module generates mist, which is delivered to the mist guide pipe via a connecting mist pipe. The mist guide pipe and the left and right oscillating components achieve relative movement and a sealed connection for the mist. The mist is then guided to the tilting mist outlet component via the air duct in the oscillating component and the connecting mist pipe in the bracket. The mist then passes through the hollow mist duct in the tilting mist outlet component and is transferred to the mist outlet of the mesh cover, thus achieving humidified mist delivery. The working principle of the circulating fan is as follows: the motor fan blade assembly is directly started to achieve the circulating air delivery function. The air delivered by the circulating fan mixes with the mist, accelerating the diffusion of the mist and achieving efficient delivery of cool air and humidification.

[0174] like Figure 4 , Figure 5 , Figure 6 and Figure 12 As shown, the mist outlet of the humidification module is sealed to the adapter mist tube, the adapter mist tube is sealed to the guide mist tube, the guide mist tube is sealed to the interface of the left and right oscillating components, the upper interface of the left and right oscillating components is fixedly connected to the lower interface of the bracket mist tube, the upper interface of the bracket adapter mist tube is fixedly connected to the connector, and the interface is connected to the mist chamber.

[0175] like Figure 10 and Figure 11 As shown, the left and right oscillating assembly enables the upper and lower halves of the machine body to rotate relative to each other. At the same time, the assembly satisfies the sealed delivery of mist. The rotating mist tube is located at the center of rotation. Specifically, the lower oscillating interface (fixed) and the rotating mist tube (moving) use an oil seal structure to seal the mist. The lower oscillating interface is fixed to the machine body. A rotating bearing is installed on the machine body for support and rotation. The upper half of the machine is connected to the machine body for relative rotation. The drive motor and gear module drive the upper half through gear transmission.

[0176] like Figure 10 As shown, the pitch fog output adapter is equipped with a rotating sealing component. The pitch air intake interface and the rotating sealing component can rotate relative to each other and are hollow structures. The fog from the bracket fog pipe interface is transmitted to the pitch air outlet interface, and finally the fog is transmitted to the fog cavity of the front shell. Then the fog is rectified by the fog output grille of the front shell to achieve the fog output effect of the whole machine.
