Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an air conditioning device. Background Technology

[0002] Air conditioning equipment is a device used to regulate the air environment. It provides a comfortable environment for people by adjusting parameters such as air temperature, humidity, and airflow direction. Common air conditioning equipment includes air conditioners, fans, and heaters. Among them, tower fans are favored by consumers due to their unique appearance and good air conditioning effect.

[0003] Tower fans adjust the airflow direction by oscillating their guide vanes. However, in related technologies, tower fans typically use a single transmission component (such as an eccentric wheel or oscillation motor) to drive all the vanes to oscillate. This design causes all vanes to oscillate to the same side, resulting in a relatively singular airflow direction and an inability to achieve multiple oscillation states. Utility Model Content

[0004] This application provides an air conditioning device designed to improve the versatility of the air conditioning device's swing states.

[0005] This application provides an air conditioning device, including: The housing has an air outlet, which is divided into a first area and a second area in the left-right direction; The impeller is used to deliver air to the air outlet; The air guiding mechanism includes two sets of fan blade assemblies disposed at the air outlet.

The other transmission member has its two ends respectively connected to the eccentric wheel and another set of fan blade assemblies. The rotational motion of the eccentric wheel drives the transmission member to reciprocate in directions toward and away from the air outlet.

[0010] In some embodiments, one of the transmission member and the drive arm is provided with a latching post, and the other of the transmission member and the drive arm is provided with a latching groove.

[0012] In some of these embodiments, the eccentric wheel is arranged in a cylindrical shape.

[0013] In some embodiments, the housing includes a frame and two sets of snap-fit ​​structures connected to the frame, the frame having the air outlet, and the two sets of snap-fit ​​structures located on opposite sides of the air outlet; The wind guide blade includes a blade body and two rotating shafts respectively connected to both ends of the blade body.

[0014] In some embodiments, the housing further includes a support member connected to the frame, and the support member has a plurality of spaced-apart support holes along the arrangement direction of the plurality of guide vanes. The blade body has a notch located between the two rotating shafts. The guide blade also includes a support shaft disposed in the notch.

[0016] In some embodiments, the housing further includes a plurality of first protective ribs and a plurality of second protective ribs disposed at the air outlet, wherein the plurality of first protective ribs are spaced apart along a first direction and the plurality of second protective ribs are spaced apart along a second direction to form a hollowed-out mesh, wherein the first direction and the second direction are set at an angle.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Air conditioning equipment is a household appliance widely used in homes, offices and other indoor environments. Its main function is to improve air quality and regulate the temperature, humidity, airflow or cleanliness of the air, thereby enhancing user comfort.

[0023] There are many types of common air conditioning equipment, such as fans, heaters, and air conditioners. This application uses a tower fan as an example to illustrate relevant embodiments, while other air conditioning equipment can be set up with reference to this example.

[0024] like Figure 1 and Figure 2 As shown, a tower fan is an electric fan with a slender shape, generally cylindrical or rectangular in shape, including a housing 10 and a fan wheel. The housing 10 can be composed of a main housing 10 and an exhaust frame. The main housing 10 is the main body 421 of the tower fan's outer shell and has an internal air duct. The exhaust frame is connected to the main housing 10 and can be securely connected to the main housing 10 by fastening screws. The main housing 10 and the exhaust frame can be made of the same material, such as engineering plastic, to balance strength, lightweight, and cost. The exhaust frame has an air outlet 10a, while the fan wheel is located inside the main housing 10. The fan wheel can draw in air, increase the kinetic energy of the air through rotating blades to generate airflow, and then send the airflow into the air duct. That is, the fan wheel is used to deliver air to the air duct. The exhaust frame is connected to the side of the main housing facing the user, and the air outlet 10a is connected to the air duct.

[0025] In other embodiments, the housing 10 may also be a tower-shaped cylindrical shell with various internal components. The tower fan also includes a base, and the housing 10 is connected to the base. The base is used to support the housing 10 and provide stability.

[0026] like Figure 3 As shown, in some embodiments, the air outlet 10a is divided into a first region 10a1 and a second region 10a2 in the left-right direction of the tower fan. The first region 10a1 and the second region 10a2 can be symmetrical or asymmetrical, without specific limitations. The air conditioning device 100 also includes an air guiding mechanism 30, a drive mechanism 20, and a transmission mechanism 40. The air guiding mechanism 30 includes two sets of fan blade assemblies 31, both of which are rotatably connected to the housing 10 and located in the first region 10a1 and the second region 10a2, respectively. This means that when the airflow passes through the first region 10a1 and the second region 10a2, it can be guided in different directions through the different swing states of the two sets of fan blade assemblies 31, thereby realizing multiple air supply modes. The drive mechanism 20 is connected to the housing 10 and is the power source of the air conditioning device 100, responsible for providing rotational power for the swing of the two sets of fan blade assemblies 31. The transmission mechanism 40 serves as a bridge connecting the drive mechanism 20 and the air guiding mechanism 30, and is responsible for converting the rotational motion output by the drive mechanism 20 into the oscillating motion of the fan blade assembly 31. Preferably, the first region 10a1 and the second region 10a2 are symmetrically arranged, and the two sets of fan blade assemblies 31 are symmetrically arranged, so that the two sets of fan blade assemblies 31 can more evenly guide the airflow in different directions.

[0027] like Figure 2As shown, the transmission mechanism 40 includes an eccentric wheel 41 and two transmission members 42. The two transmission members 42 are respectively connected to the eccentric wheel 41 and a set of fan blade assemblies 31. The rotational motion of the eccentric wheel 41 drives the transmission members 42 to reciprocate in directions toward and away from the air outlet 10a. The transmission members 42 then cause the corresponding fan blade assembly 31 to swing relative to the housing 10. The eccentric wheel 41 is connected to the output shaft of the drive mechanism 20. The axis of the output shaft of the drive mechanism 20 is the rotation axis of the eccentric wheel 41 connected to it. The rotation axis of the eccentric wheel 41 is off-center. When the eccentric wheel 41 rotates, it generates a periodic eccentric force. This eccentric force acts on the transmission members 42, pushing the transmission members 42 to move in a specific direction. The transmission members 42 are in direct contact with the eccentric wheel 41. The rotational motion of the eccentric wheel 41 is converted into the reciprocating linear motion of the transmission members 42 through this contact. The transmission members 42 further drive the corresponding fan blade assembly 31, enabling it to swing relative to the housing 10. By controlling the geometry of the eccentric wheel 41 and the connection method of the transmission component 42, the swing angle range and speed of the fan assembly 31 can be precisely controlled. The eccentricity of the eccentric wheel 41 determines the swing amplitude, and the motor speed determines the swing frequency.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, the eccentric wheel 41 drives the transmission component 42 to reciprocate in the direction towards and away from the air outlet 10a. The rotation axis of the eccentric wheel 41 cannot be parallel to the direction in which the transmission component 42 approaches or moves away from the air outlet 10a; that is, the rotation axis of the eccentric wheel 41 is set at an angle to the direction in which the transmission component 42 approaches or moves away from the air outlet 10a. Preferably, the rotation axis of the eccentric wheel 41 is set perpendicular to the direction in which the transmission component 42 approaches or moves away from the air outlet 10a. In this way, when using the same eccentric wheel 41, the movement stroke of the transmission component 42 in the direction in which it approaches or moves away from the air outlet 10a is larger, thereby increasing the oscillation amplitude of the fan blade assembly 31.

[0029] Both transmission components 42 are connected to the eccentric wheel 41. During the rotation of the eccentric wheel 41, the eccentric wheel 41 will drive the two transmission components 42 to move synchronously in the direction of approaching or moving away from the air outlet 10a, that is, to move simultaneously in the direction of approaching the air outlet 10a or to move simultaneously in the direction of moving away from the air outlet 10a.

[0030] In one configuration, two sets of fan blade assemblies 31 are arranged along a first direction of the housing 10. Each fan blade assembly 31 includes multiple guide vanes 311, which are spaced apart along the first direction. Each guide vane 311 can swing along the first direction of the air outlet frame. In another configuration, two sets of fan blade assemblies 31 are arranged along a second direction of the air outlet frame. Each fan blade assembly 31 includes multiple guide vanes 311, which are spaced apart along the second direction. Each guide vane 311 can swing along the second direction of the air outlet frame. The first direction and the second direction are set at an angle. In this embodiment, the first direction can be the width direction of the tower fan, and the second direction can be the height direction of the tower fan. Understandably, the guide vanes 311 have an extending direction. In the first configuration described above, the guide vanes 311 extend along the height direction, and the multiple guide vanes 311 are evenly spaced along the width direction on the housing 10. Correspondingly, the guide vanes 311 can sway to the left and right to change the swing state of the tower fan. In the second configuration described above, the guide vanes 311 extend along the width direction, and multiple guide vanes 311 are evenly spaced along the height direction. Correspondingly, the guide vanes 311 can be tilted up and down to change the oscillation state of the tower fan. It should be noted that the number of guide vanes 311 in the two sets of fan blade assemblies 31 can be different or the same. Preferably, the number of guide vanes 311 in the two sets of fan blade assemblies 31 is the same, which makes the airflow guided by the two sets of guide assemblies more uniform.

[0031] like Figure 1 As shown, in this embodiment, the two sets of fan blade assemblies 31 are arranged along the width direction of the tower fan as an example. The guide blades 311 extend along the height direction of the tower fan, which can achieve long-distance air delivery effect. That is, the two sets of fan blade assemblies 31 can swing left and right to meet the air delivery needs of different positions.

[0032] Furthermore, each fan blade assembly 31 in this embodiment is equipped with three guide vanes 311, and the tower fan has a total of six guide vanes 311. The total number of guide vanes 311 is related to the size of the air duct; the larger the air duct, the more guide vanes 311 can be arranged accordingly. If too many guide vanes 311 are set, the spacing between the guide vanes 311 will be too dense, increasing airflow resistance. Therefore, setting the appropriate number of guide vanes 311 according to the size of the air duct can balance factors such as air volume and airflow feel to achieve the best overall air delivery effect.

[0033] like Figure 2As shown, in some embodiments, the guide vane 311 includes a vane body 3112 and two rotating shafts 3113 respectively connected to both ends of the vane body 3112. The "rotating shafts 3113" refer to the shafts or shaft-like structures provided at both ends of the guide vane 311 along its own length direction (extension direction) for supporting the vane and allowing it to rotate about that point. They are the pivot points for the deflection motion of the guide vane 311.

[0034] The housing 10 includes a frame 12 and two sets of snap-fit ​​structures 13 connected to the frame 12. The frame 12 has an air outlet 10a, and the two sets of snap-fit ​​structures 13 are located on opposite sides of the air outlet 10a. The two sets of snap-fit ​​structures 13 on the housing 10 (located on both sides of the air outlet 10a) provide a reference for the installation and positioning of the guide vanes 311. The rotating shafts 3113 at both ends of the guide vanes 311 need to be snapped into the corresponding snap-fit ​​structures 13 on both sides of the housing 10.

[0035] The snap-fit ​​structure 13 includes multiple elastic snaps 131, each corresponding to a multiple rotating shaft 3113. Each elastic snap 131 has a slot, within which the rotating shaft 3113 is engaged and can rotate, allowing the guide vane 311 to deflect around the rotating shaft 3113 at both ends. The slots provided by the elastic snap 131 offer a rotating interface, forming the basis for achieving dynamic effects such as blade opening and closing, and oscillation.

[0036] Specifically, the elastic buckle 131 includes a first buckle portion and a second buckle portion, which are arranged opposite to each other and define a buckle groove. The first buckle portion and the second buckle portion can separate from each other when subjected to external force. When installing the rotating shaft 3113, the rotating shaft 3113 can be quickly installed by pressing it apart.

[0037] like Figure 3 As shown, in some embodiments, the housing 10 has a first side 10b and a second side 10c that are opposite to each other. The first side 10b and the second side 10c are the two sides of the tower fan that are opposite to each other in the front-back direction. The first side 10b is provided with a fan blade assembly 31. The first side 10b is the front side of the tower fan, that is, the side facing the user. The second side 10c is provided with a connecting seat 11. The connecting seat 11 is used to provide a support platform for the drive mechanism 20. The connecting seat 11 has a first connecting hole, and the drive mechanism 20 has a second connecting hole. The drive mechanism 20 is fixedly connected to the connecting seat 11 by fasteners passing through the second connecting hole and the first connecting hole. This provides a very strong fixing method, which can withstand the torque and vibration generated by the drive mechanism 20 during operation, prevent the drive mechanism 20 from being displaced or loosened during operation, and improve the overall structural stability and assembly convenience of the product.

[0038] Understandably, there are two of each of the first and second connecting holes, with the two second connecting holes located on the radial sides of the drive mechanism 20, making the drive mechanism 20 more securely and evenly fixed on the connecting seat 11.

[0039] like Figure 2 As shown, in some embodiments, the housing 10 also has a mounting port 10d connecting the first side 10b and the second side 10c. The mounting port 10d is arranged adjacent to the connecting seat 11. The transmission assembly is disposed at the mounting port 10d for transmission connection with the fan blade assembly 31. This allows a portion of the transmission assembly to extend more directly from the side where the drive mechanism 20 is located, reaching the fan blade assembly 31 through this mounting port 10d. During assembly, it is easier to install the transmission assembly in place and connect it to the drive mechanism 20 and the fan blade assembly 31.

[0040] In some embodiments, each set of fan blade assemblies 31 includes multiple guide vanes 311. Each guide vane 311 includes an interconnected guide section and a transmission section in the direction of movement of the transmission member 42. The guide section is rotatably mounted on the housing 10, and the guide section and transmission section are arranged at an angle. The transmission sections of one set of fan blade assemblies 31 and the transmission sections of another set of fan blade assemblies 31 extend in directions that are closer to or further away from each other. The transmission member 42 is connected to the transmission section in a transmission manner. When the drive mechanism 20 drives the eccentric wheel 41 to rotate, the transmission member 42 pushes the transmission section to swing forward or backward synchronously. Because the transmission sections of the two sets of fan blade assemblies 31 extend in opposite directions, the guide sections of the two sets of fan blade assemblies 31 swing in opposite directions during the swinging process. The two sets of fan blade assemblies 31 swing mirror-imagely, either moving closer to the center or deflecting to the left or right.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, each set of wind blade assembly 31 includes multiple guide blades 311. The guide blade 311 includes a blade body 3112 and a drive arm 3115. The blade body 3112 is rotatably connected to the housing 10. The drive arm 3115 is connected to the plate surface of the blade body 3112 and is set at an angle to the plate surface. The plate surface connected to the drive arm 3115 in one set of wind blade assembly 31 is connected to the plate surface connected to the drive arm 3115 in another set of wind blade assembly 31. One transmission member 42 is drivenly connected to the drive arm 3115 of one set of wind blade assembly 31, and another transmission member 42 is drivenly connected to the drive arm 3115 of another set of wind blade assembly 31. With this configuration, when the drive mechanism 20 drives the eccentric wheel 41 to rotate, the transmission component 42 pushes the drive arm 3115 to swing forward or backward synchronously. By setting the drive arms 3115 of the two sets of fan blade assemblies 31 facing each other or back to back, the blade bodies 3112 of the two sets of fan blade assemblies 31 swing in opposite directions during the swing of the drive arm 3115. As a result, the two sets of fan blade assemblies 31 swing in a mirror image, either converging towards the center or deflecting to the left or right. It can be seen that the two sets of fan blade assemblies 31 have a converging swing state, a dispersing swing state, and a parallel swing state. At the same time, the area occupied by the drive arm 3115 in the air outlet path of the wind turbine is small, which can effectively reduce the turbulence effect of the drive arm 3115 on the air blown out by the wind turbine.

[0042] Considering that the plate surface connected to the drive arm 3115 in one set of fan blade assemblies 31 faces the plate surface connected to the drive arm 3115 in another set of fan blade assemblies 31, in order to avoid interference between the drive arms 3115 of the guide blades 311 of the two sets of fan blade assemblies 31 during the rotation of the guide blades 311, it is necessary to increase the spacing between the blade bodies 3112 of the two sets of fan blade assemblies 31. Therefore, as follows... Figure 3 As shown, the plate surface connected to the drive arm 3115 in one set of fan blade assemblies 31 is arranged opposite to the plate surface connected to the drive arm 3115 in another set of fan blade assemblies 31. This ensures that the drive arms 3115 of the guide blades 311 of the two sets of fan blade assemblies 31 do not interfere with each other during the rotation of the guide blades 311. As a result, the distance between the blade bodies 3112 of the two sets of fan blade assemblies 31 is smaller, thereby improving the air guiding effect of the air conditioning device 100.

[0043] Meanwhile, the distance between the rotation axes of any two adjacent blade bodies 3112 can be set to be the same, so that the oscillation device can guide the wind blown out by the wind turbine more evenly.

[0044] like Figure 2As shown, in this embodiment, the centerline of the drive arm 3115 is perpendicular to the plate surface, which reduces the moving distance of the transmission member 42 in the arrangement direction of the blade body 3112. Furthermore, the centerline of the drive arm 3115 is coplanar with the rotation axis of the blade body 3112, which avoids the lateral bending moment generated when the transmission member 42 drives the arm 3115 to cause a large load on the blade body 3112, thereby effectively protecting the blade body 3112, extending its lifespan, and improving the transmission stability between the transmission member 42 and the drive arm 3115.

[0045] In the parallel swing state, the guide vanes 311 extend approximately along the front-to-back direction of the tower fan. Specifically, with the guide vanes 311 in the parallel swing state defined as a 0° sway, the guide vanes 311 can sway 30° to the left and 30° to the right. In other words, the swing angle of the guide vanes 311 is limited to approximately between 30° to the left and 30° to the right.

[0046] In practical use, this tower fan is currently equipped with two main operation buttons: a "Power On / Off" button and a "Swing-Pause" button. These buttons simplify user operation and enable switching and pausing control between convergent oscillation, dispersed oscillation, and parallel oscillation modes. The "Swing-Pause" button functions as follows: when the tower fan's guide vanes 311 are oscillating, pressing this button immediately pauses the current oscillation and stabilizes the fan at the desired wind direction, such as a parallel left oscillation. Users can experience the wind effect in this paused state. If the user wishes to change the wind direction or switch modes, simply press the "Swing-Pause" button again. This rotates the drive mechanism 20, driving the eccentric wheel 41 and transmission mechanism 40, causing the guide vanes 311 to switch from the current paused position to either convergent or dispersed oscillation, thus entering the switching state. Pressing the "Swing-Pause" button again pauses the tower fan once more. This button design allows users to flexibly switch between continuous oscillation and fixed-point airflow.

[0047] Based on the above embodiments, we limit the observation of the tower fan to a top-down view, and define the upper part of the guide vane 311 in the top view as the upper part. From this perspective, as the drive mechanism 20 drives the eccentric wheel 41 to rotate, the tower fan will undergo a cycle of swing state switching. It can start in a parallel swing state; however, this is not a mandatory starting point. It depends on the state at which the fan was paused during the last shutdown. When the drive mechanism 20 continues to rotate, after approximately 90°, the tower fan will switch from the parallel swing state to a dispersed swing state. At this time, the two sets of fan blade assemblies 31 will mirror each other and swing to the left and right, creating a dispersed effect. If the drive mechanism 20 continues to rotate approximately 90° (accumulating approximately 180°), the tower fan will switch from the dispersed swing state back to the parallel swing state. After rotating another approximately 90° (accumulating approximately 270°), the tower fan will switch to a converging swing state, at which point the two sets of fan blade assemblies 31 will mirror each other and move closer to the center. When the drive mechanism 20 completes a full 360° rotation, the tower fan will return to the initial parallel swing state, thus completing a cycle of convergent and dispersed swing states, namely, the cycle switching of parallel swing -> dispersed swing -> parallel swing -> converged swing -> parallel swing.

[0048] Based on the above configuration, we will illustrate the state switching process in actual use with an example. For instance, in actual use, the user pauses the tower fan in the convergent swing state, at which point both sets of fan blade assemblies 31 move towards the center of the tower fan. If the user wants to switch to the dispersed swing state, they need to click the "Swing Head - Pause" button. This operation will cause the drive mechanism 20 to start rotating, and the eccentric wheel 41 will start driving the two transmission components 42 and the fan blade assembly 31 to move. After experiencing parallel swing, it enters the dispersed swing state. At this point, the user clicks the "Swing Head - Pause" button, causing the tower fan to pause in the dispersed swing state.

[0049] like Figure 3 As shown, in some embodiments, the eccentric wheel 41 is cylindrical, which simplifies the structure of the eccentric wheel 41, reduces the cost of the air conditioning equipment 100, and can reduce the transmission friction between the eccentric wheel 41 and the transmission component 42, so that the eccentric wheel 41 can better drive the transmission component 42 to move back and forth in the direction close to the air outlet 10a and away from the air outlet 10a.

[0050] like Figure 3 and Figure 6As shown, in some embodiments, the transmission member 42 has a guide groove 42a, and the eccentric wheel 41 is disposed within the guide groove 42a. The guide groove 42a restricts the rotation of the eccentric wheel 41. The guide groove 42a has a length direction and a width direction. In this embodiment, the length direction is the same as the left-right direction of the tower fan, and the width direction is the same as the front-back direction of the tower fan. Understandably, the motion trajectory of the eccentric wheel 41 can be decomposed into two components along the length direction and the width direction of the guide groove 42a. The guide groove 42a has a first sidewall 42a1 and a second sidewall 42a2 that are opposite and parallel to each other along the width direction. Both the first sidewall 42a1 and the second sidewall 42a2 extend along the length direction, and both the first sidewall 42a1 and the second sidewall 42a2 slide in contact with the outer wall of the eccentric wheel 41. This allows the eccentric wheel 41 to slide freely relative to each other along the length direction of the guide groove 42a. This means that the component along the length direction of the eccentric wheel 41's motion trajectory mainly manifests as the positional change of the eccentric wheel 41 within the guide groove 42a, rather than directly transmitting as a displacement of the entire transmission component 42 along that direction (the left-right direction of the tower fan). When the eccentric wheel 41's motion generates a displacement component along the width direction, due to the obstruction of the first sidewall 42a1 and the second sidewall 42a2 (a small displacement under sliding fit), a contact force (normal force) is generated between it and the first sidewall 42a1 or the second sidewall 42a2. This force acts on the first sidewall 42a1 or the second sidewall 42a2 of the transmission component 42, driving the transmission component 42 to generate displacement in the width direction (the front-back direction of the tower fan).

[0051] like Figure 6 As shown, in this embodiment, the transmission member 42 is configured as a flat plate structure, while the guide groove 42a is specifically embodied as a U-shaped groove. This choice of shape intuitively reflects both the length direction (the extension direction of the U-shaped groove) and the width direction (the opening width direction of the U-shaped groove). The flat plate structure facilitates integration and installation, while the U-shaped groove provides the required guiding and sliding interface in a simple and efficient manner.

[0052] like Figure 2As shown, in some embodiments, each fan blade assembly 31 includes multiple spaced-apart guide vanes 311. One of the transmission member 42 and the guide vanes 311 is provided with a retaining post 3111, and the other is provided with a retaining groove 42b. The retaining post 3111 is disposed within the retaining groove 42b, and there is a certain gap between the retaining post 3111 and the retaining groove 42b, allowing the guide vane 311 to deflect around its own pivot point when subjected to the force of the transmission member 42. That is, the retaining groove 42b does not tightly clamp the retaining post 3111, but allows relative rotation. Through the cooperation of the retaining post 3111 and the retaining groove 42b, the guide vane 311 can be driven by the transmission member 42 to deflect. The retaining groove 42b and the retaining post 3111 connect the guide vane 311 to the transmission member 42, ensuring that the guide vane 311 can move with the movement of the transmission member 42.

[0053] like Figure 2 As shown, in this embodiment, the transmission component 42 is provided with a retaining groove 42b, the opening of which faces opposite to the opening of the guide groove 42a. The guide vane 311 is provided with a retaining post 3111. Understandably, as described above, the retaining post 3111 and the retaining groove 42b are located at the mounting opening 10d. To facilitate connection with the retaining groove 42b, the retaining post 3111 is positioned closer to the second side 10c than the rotating shaft 3113. The central axis of the retaining post 3111 extends vertically. When the retaining groove 42b moves to the left, its right sidewall will press against the retaining post 3111. The retaining post 3111 is part of the guide vane 311. This leftward force acting on the retaining post 3111 is equivalent to acting on the guide vane 311 near the pivot point, applying a leftward thrust. This leftward thrust generates a torque relative to the pivot point of the guide vane 311. According to the lever principle, this torque will cause the guide vane 311 to rotate around its pivot point, and the guide vane 311 will deflect to the right.

[0054] It should be noted that the corresponding mounting posts 3111 of the guide vanes 311 of the two sets of fan blade assemblies 31 are not at the same height. The mounting posts 3111 need to be connected to the transmission component 42. The driving components of the transmission component 42 that drive these two mounting posts 3111—the first eccentric part and the second eccentric part—are not located on the same horizontal line, but have a certain height difference. The first eccentric part is positioned above the second eccentric part. This staggered design in height... Understandably, in other embodiments, the transmission component 42 may also be configured as a latch 3111, and the air guide blade 311 is provided with a latch groove 42b. The principle is similar to the above configuration, and will not be described again here.

[0055] like Figure 3 and Figure 6As shown, the transmission component 42 further includes a main body 421 and a plurality of fasteners 422 connected to the outer edge of the main body 421. The main body 421 has a guide groove 42a. The plurality of fasteners 422 are arranged in a one-to-one correspondence with a plurality of fastening posts 3111. In this embodiment, one guide vane 311 has one fastening post 3111. That is to say, a set of fan blade assemblies 31 includes a plurality of guide vanes 311. The plurality of guide vanes 311 are all guided and deflected by the plurality of fasteners 422 on a transmission component 42.

[0056] Fastener 422 includes two fastening parts with an arc-shaped clamping structure. The arc-shaped clamping structure provides more uniform contact and support. The two fastening parts define a fastening groove 42b. The fastening post 3111 can deflect along the groove wall of the fastening post 42b to adjust the deflection angle of the guide vane 311, reducing swaying or jamming during the deflection process. The fastening post 3111 deflects along the arc-shaped groove wall, and the trajectory is more in line with the design expectation, making the adjustment of the deflection angle of the guide vane 311 more stable and precise.

[0057] Among them, the two arc-shaped clamping structures can be elastic arc-shaped clamping structures. Before installing the buckle 3111, by applying a relatively small external force (such as prying it open by hand), the two elastic arc-shaped structures that should be tightly fitted or fastened can be forcibly separated to form a sufficiently large gap. At this time, the user can easily insert the buckle 3111 on the air guide blade 311 into the corresponding position set on the transmission component 42 through this gap. Once the buckle 3111 is correctly installed in place and the external force is removed, the elastic arc-shaped structure will automatically return to its original shape by its own rebound force and re-encircle the buckle 3111.

[0058] Because the guide vane 311 extends quite far, if it is only supported by the rotating shafts 3113 at both ends, the middle part of the vane will lack support when it deflects or is impacted by airflow, and it is prone to bending, deformation or even uneven twisting.

[0059] like Figure 2 As shown, in order to solve the above problems, in some embodiments, the housing 10 further includes a support member 14, which is connected to the frame 12 and is arranged along the direction of the arrangement of multiple air guide blades 311. For example, in this embodiment, the air guide blades 311 are arranged along the width direction of the tower fan. Therefore, the support member 14 has multiple support holes 14a arranged at intervals along the width direction.

[0060] The blade body 3112 has a notch 3112a located between two rotating shafts 3113. The guide blade 311 also includes a support shaft 3114, which is disposed in the notch 3112a. The support shaft 3114 is connected to the top wall of the notch 3112a and extends downward. Multiple support shafts 3114 are correspondingly arranged with multiple support holes 14a, and a portion of the support shaft 3114 is rotatably disposed within the support hole 14a. It is not merely a fixed fulcrum, but a guiding structure that assists the guide blade 311 in synchronous and smooth deflection. By adding a support in the middle of the blade, the forces experienced by the blade during movement (such as airflow resistance, its own weight, and inertial forces during deflection) can be distributed to three points (two rotating shafts 3113 points + one support point), instead of being concentrated at both ends, thus making the force on the guide blade 311 more even.

[0061] Furthermore, the housing 10 also has two receiving slots 10f, which are arranged opposite to each other along the arrangement direction of the multiple guide vanes 311. The receiving slots 10f can be square slots, and a connecting clamping channel 10e is formed between the two receiving slots 10f.

[0062] like Figure 7 As shown, the support member 14 includes two support blocks 141 and a support plate 142 connected to the two support blocks 141. The support blocks 141 are cuboid in shape and are adapted to the size of the receiving groove 10f. The support plate 142 has a support hole 14a and is a flat plate structure. It is embedded in the receiving groove 10f through the support blocks 141 and is locked in the clamping channel 10e. The housing 10 can firmly fix the support member 14 to prevent it from loosening, shifting or falling off.

[0063] The receiving groove 10f and the clamping channel 10e provide a precise installation position and orientation for the support member 14. The support hole 14a on the support plate 142 is aligned with the position of the air guide blade 311, ensuring the realization of the intermediate support function. Since the installation position is precisely defined, the assembly differences between different products will be reduced, ensuring the consistency of the installation of the support member 14, and thus ensuring the stability of the support effect of the air guide blade 311.

[0064] like Figure 2As shown, in some embodiments, the housing 10 further includes a plurality of first protective ribs 15 and a plurality of second protective ribs 16 disposed at the air outlet 10a. The plurality of first protective ribs 15 are arranged at intervals along a first direction, and the plurality of second protective ribs 16 are arranged at intervals along a second direction. As mentioned above, the first direction is the width direction of the tower fan, and the second direction is the height direction of the tower fan. It can be understood that the first protective ribs 15 extend along the height direction, and the second protective ribs 16 extend along the width direction to form a hollow mesh. The purpose of setting the first protective ribs 15 and the second protective ribs 16 is to prevent the user's fingers or foreign objects from being inserted into the air inlet.

[0065] The clamping channel 10e is defined by multiple first protective ribs 15 or multiple second protective ribs 16. By utilizing the structure of the first protective ribs 15 and the second protective ribs 16 themselves, the component of separately setting the clamping channel 10e is eliminated. The support member 14 (as mentioned before) is directly inserted into the channel defined by the ribs, which simplifies the structure, reduces costs, and may improve assembly efficiency.
