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

[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 1As shown, a tower fan is an electric fan with a slender shape, generally cylindrical or rectangular in shape, including a fan wheel and a housing 10. The housing 10 can be composed of a main housing 10 and an air outlet frame. The main housing 10 is the main body 431 of the tower fan's outer shell and has an internal air duct. The air outlet 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 air outlet frame can be made of the same material, such as engineering plastic, to balance strength, lightweight, and cost. The air outlet 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 air outlet 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 2 As shown, in some embodiments, the air conditioning device 100 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. This means that airflow can be guided in different directions through different oscillation states of the two sets of fan blade assemblies 31, thereby achieving 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 oscillation of the two sets of fan blade assemblies 31. The transmission mechanism 40 is a bridge connecting the drive mechanism 20 and the air guiding mechanism 30, responsible for converting the rotational motion output by the drive mechanism 20 into the oscillation motion of the fan blade assemblies 31.

[0027] like Figure 2As shown, the transmission mechanism 40 includes a driving wheel 41, a driven wheel 42, and two transmission components 43. The driving wheel 41 is connected to the output shaft of the drive mechanism 20. The driving wheel 41 is provided with a first transmission column 411, which is spaced apart from the shaft of the driving wheel 41. The driven wheel 42 is provided with a second transmission column 421, which is spaced apart from the shaft of the driven wheel 42. The driving wheel 41 and the driven wheel 42 abut against each other for transmission. The driven wheel 42 can be driven by the driving wheel 41. The driving wheel 41 and the driven wheel 42 rotate in different directions. That is, when the driving wheel 41 rotates clockwise, the driven wheel 42 rotates counterclockwise, and vice versa. There are many ways in which the driving wheel 41 and the driven wheel 42 can be driven by contact. For example, both the driving wheel 41 and the driven wheel 42 are friction wheels, and the driving wheel 41 and the driven wheel 42 transmit power through friction when they contact each other. Or, both the driving wheel 41 and the driven wheel 42 are gears, and the driving wheel 41 and the driven wheel 42 mesh to transmit power through gear meshing. These are just a few examples.

[0028] The axis of the output shaft of the drive mechanism 20 is the rotation axis of the drive wheel 41. The centerline of the first transmission column 411 is offset from the rotation axis of the drive wheel 41. When the drive wheel 41 rotates, the first transmission column 411 rotates around the rotation axis of the drive wheel 41 and acts on the corresponding transmission component 43, pushing the transmission component 43 to move in a specific direction. The centerline of the second transmission column 421 is offset from the rotation axis of the driven wheel 42. When the driven wheel 42 rotates, the second transmission column 421 rotates around the rotation axis of the driven wheel 42 and acts on the corresponding transmission component 43, pushing the transmission component 43 to move in a specific direction.

[0029] like Figure 3 As shown, the rotation axis of the driving wheel 41 is offset from its center position. When the eccentric wheel rotates, it generates a periodic eccentric force. This eccentric force acts on the transmission component 43, pushing it to move in a specific direction. One end of each of the two transmission components 43 is connected to the first transmission column 411 and the second transmission column 421, respectively, and the other end is connected to two sets of fan blade assemblies. The two transmission components 43 are in direct contact with the first transmission column 411 and the second transmission column 421, respectively. The movement of the first transmission column 411 and the second transmission column 421 is converted into the reciprocating linear motion of the transmission component 43 through this contact. The transmission component 43 further drives the corresponding fan blade assembly 31, enabling it to oscillate relative to the housing 10. Through the connection method of the transmission components 43, the oscillation angle range and speed of the fan blade assembly 31 can be precisely controlled. The distance between the first transmission column 411 and the rotation axis of the driving wheel 41, and the distance between the second transmission column 421 and the rotation axis of the driven wheel 42, determine the amplitude of the oscillation, and the motor speed determines the frequency of the oscillation.

[0030] When the drive mechanism 20 drives the driving wheel 41 to rotate, the driving wheel 41 drives the driven wheel 42 to rotate. The first transmission column 411 and the second transmission column 421 respectively drive the two transmission components 43 to move in opposite directions, causing the two sets of fan blade assemblies 31 to swing in opposite directions. This allows the two sets of fan blade assemblies 31 to be roughly close together, i.e., converged airflow, or to swing away from each other, i.e., dispersed airflow. Converged airflow can concentrate and guide airflow to a specific area, which is suitable for scenarios requiring strong airflow. Dispersed airflow can spread airflow to a wider area, allowing users in different locations within the space to feel a cool breeze.

[0031] 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 air guide blades 311 extend along the width direction, and multiple air guide blades 311 are evenly spaced along the height direction. Correspondingly, the air guide blades 311 can be tilted up and down to change the swing state of the tower fan.

[0032] like Figures 7 to 9 As shown, in some embodiments, one set of fan blade assemblies 31 includes at least two first fan blades 31a, and another set of fan blade assemblies 31 includes at least two second fan blades 31b. At least one second fan blade 31b is disposed between the at least two first fan blades 31a. Each first fan blade 31a is driven to a transmission member 43, and each second fan blade 31b is driven to another transmission member 43. This allows the two sets of fan blade assemblies 31 to achieve both side-dispersed air delivery and center-converged air delivery in one state through the staggered arrangement of the first fan blades 31a and the second fan blades 31b. In another state, multi-point converged air delivery can be achieved to improve the air delivery intensity of the tower fan assembly, thereby meeting the diverse needs of users.

[0033] There are many possible arrangements of the first wind vane 31a and the second wind vane 31b, for example, as follows: Figure 7As shown, the first wind vane 31a and the second wind vane 31b are arranged alternately in the left-right direction, that is, there is one second wind vane 31b between two first wind vanes 31a; or, multiple second wind vanes 31b are arranged between two first wind vanes 31a; or, for example, ... Figure 8 As shown, the first wind vane 31a, the second wind vane 31b, the second wind vane 31b, the first wind vane 31a, the first wind vane 31a, and the second wind vane 31b are arranged sequentially in the left-right direction; for example, as... Figure 9 As shown, the first wind vane 31a, the second wind vane 31b, the first wind vane 31a, and the second wind vane 31b are arranged sequentially in the left-right direction. They will not be listed one by one here.

[0034] like Figures 3 to 6 As shown, in this embodiment, the air outlet 10a is divided into a first region 10a1 and a second region 10a2 in the left and right directions. Two sets of fan blade assemblies 31 are rotatably installed in the first region 10a1 and the second region 10a2, so that the air blown out by the fan wheel passes through the first region 10a1 and the second region 10a2, and is guided by the two sets of fan blade assemblies 31 to disperse to the left and right sides or to be guided to the middle to gather, thereby realizing air delivery in multiple directions and meeting the diverse needs of users.

[0035] like Figure 3 As shown, the two sets of fan blade assemblies 31 can be symmetrically arranged, that is, both sets of fan blade assemblies 31 have multiple fan blades, the number of fan blades in the two sets of fan blade assemblies 31 is the same, and they are respectively arranged in the first region 10a1 and the second region 10a2, as shown. Figure 6 As shown, the two sets of fan blade assemblies 31 can also be arranged asymmetrically, that is, the number of fan blades in the two sets of fan blade assemblies 31 is different. For example, one set of fan blade assemblies 31 has two fan blades, two guide vanes 311 are rotatably mounted in the first area 10a1 and are connected to a transmission component 43. The other set of fan blade assemblies 31 has four fan blades, four guide vanes 311 are rotatably mounted in the second area 10a2 and are connected to another transmission component 43. These are not listed one by one here.

[0036] In this embodiment, the two sets of fan blade assemblies 31 are arranged along the left and right directions 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.

[0037] 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.

[0038] like Figure 3 As shown, in some embodiments, both the driving wheel 41 and the driven wheel 42 are gears. The transmission between the driving wheel 41 and the driven wheel 42 is achieved through gear meshing, which provides advantages such as high transmission efficiency, low energy loss, stable transmission ratio, and high transmission accuracy.

[0039] To facilitate understanding, the following description will take the example of two sets of guide vanes 311 being rotatably installed in the first region 10a1 and the second region 10a2, respectively.

[0040] like Figure 3 As shown, in some embodiments, the number of teeth on the drive wheel 41 is the same as that on the driven wheel 42, which can be understood as the drive wheel 41 and the driven wheel 42 having the same size. The two sets of fan blade assemblies 31 are arranged in the left-right direction. The drive mechanism 20 drives the drive wheel 41 to rotate and drives the driven wheel 42 to rotate. The first transmission column 411 and the second transmission column 421 respectively drive the two transmission components 43 to reciprocate in the left-right direction in the directions of mutual orientation and distance.

[0041] At this time, when the drive mechanism 20 drives the drive wheel 41 to rotate, and the first transmission column 411 drives the transmission component 43 to push the corresponding fan blade assembly 31 to swing to one side, the transmission component 43 will rotate in the opposite phase under the transmission of the drive wheel 41. The second transmission column 421 drives the transmission component 43 to push the corresponding fan blade assembly 31 to swing to the opposite side. In this state, the two sets of fan blade assemblies 31 will 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 dispersed swing state, and a parallel swing state.

[0042] like Figure 5 and Figure 6As shown, in one embodiment, the driving wheel 41 and the driven wheel 42 are arranged in a left-right direction. When the two fan blade assemblies 31 are in a converged or dispersed state, the first transmission column 411 is located on the side of the driving wheel 41's axis of rotation away from the driven wheel 42, and the second transmission column 421 is located on the side of the driven wheel 42's axis of rotation away from the driving wheel 41. Alternatively, the first transmission column 411 is located on the side of the driving wheel 41's axis of rotation closer to the driven wheel 42, and the second transmission column 421 is located on the side of the driven wheel 42's axis of rotation closer to the driving wheel 41. At this time, during the rotation of the driving wheel 41 and the driven wheel 42, the first transmission column 411 and the second transmission column 421 will reciprocate in the left-right direction towards each other or away from each other, thereby driving the two sets of fan blade assemblies 31 to swing back and forth.

[0043] In another embodiment, the driving wheel 41 and the driven wheel 42 are arranged in a front-to-back direction. When the two fan blade assemblies 31 are in a converged or dispersed state, the first transmission column 411 and the second transmission column 421 are located on both sides of the axis of rotation of the driving wheel 41 in the left-to-right direction, respectively. At this time, during the rotation of the driving wheel 41 and the driven wheel 42, the first transmission column 411 and the second transmission column 421 will reciprocate in the left-to-right direction in a direction that moves closer to or further away from each other, thereby driving the two sets of fan blade assemblies 31 to swing back and forth.

[0044] like Figure 10 As shown, in some embodiments, the number of teeth on the driving wheel 41 is different from the number of teeth on the driven wheel 42. In this case, the transmission ratios of the driving wheel 41 and the driven wheel 42 are different, causing the first transmission column 411 and the second transmission column 421 to switch between moving to the left together, moving closer to each other, moving to the right together, and moving away from each other in the left-right direction. This causes the transmission component 43 to drive the two sets of fan blade assemblies 31 to switch between swinging to the right together, swinging away from each other, swinging to the left together, and swinging closer to each other. It can be seen that the two sets of fan blade assemblies 31 have a right-swinging state, a dispersed swinging state, a left-swinging state, a converged swinging state, and a medium-swinging state, thereby realizing multiple blowing states of the tower fan and meeting the diverse needs of users.

[0045] Specifically, the number of teeth of the driving wheel 41 is greater than the number of teeth of the driven wheel 42. Since the force required for the transmission component 43 to drive the fan blade assembly 31 to swing is smaller, the torque of the driven wheel 42 can be appropriately reduced to enable the driven wheel 42 to have a larger rotation speed, which can increase the speed of the transmission component 43 connected to the driven wheel 42.

[0046] Furthermore, the number of teeth of the driving wheel 41 is Z1, the number of teeth of the driven wheel 42 is Z2, and the transmission ratio between the driving wheel 41 and the driven wheel 42 is Z1 / Z2, where Z1 / Z2 = 1.25. Taking the state of the driving wheel 41 and the driven wheel 42 before rotation as the initial state, after the driving wheel 41 rotates 4 times, the driving wheel 41 and the driven wheel 42 will return to the initial state to complete one oscillation cycle, which makes the oscillation state of the air conditioning device 100 more controllable.

[0047] For ease of understanding, the guide vanes 311 shown in the parallel swing state extend approximately along the front-to-back direction of the tower fan. Specifically, the guide vanes 311 in the parallel swing state are defined as having a 0° sway. The guide vanes 311 can sway 30° to the left and 30° to the right; that is, the swing angle of the guide vanes 311 is limited to approximately between 30° to the left and 30° to the right.

[0048] For example, taking the parallel swing state as the initial state, after the drive wheel 41 rotates one revolution, the guide vane 311 connected to the first drive column 411 via the transmission member 43 is at 0°, and the guide vane 311 connected to the second drive column 421 via the transmission member 43 is swinging 30° to the left; after the drive wheel 41 rotates another revolution, the guide vane 311 connected to the first drive column 411 via the transmission member 43 is at 0°, and the guide vane 311 connected to the second drive column 421 via the transmission member 43 is swinging 30° to the left. 11 is 0°; after the drive wheel 41 rotates one more revolution, the guide vane 311 connected to the first drive column 411 via the transmission component 43 is 0°, and the guide vane 311 connected to the second drive column 421 via the transmission component 43 is tilted 30° to the right; after the drive wheel 41 rotates one more revolution, the guide vane 311 connected to the first drive column 411 via the transmission component 43 is 0°, and the guide vane 311 connected to the second drive column 421 via the transmission component 43 is 0°, and so on.

[0049] like Figure 2 As 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] like Figure 3 and Figure 10 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 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.

[0054] like Figure 2As shown, to prevent the external environment from affecting the transmission of the driving wheel 41 and the driven wheel 42, in this embodiment of the application, the air conditioning device 100 further includes a protective box 50, which is installed on the connecting seat 11. The driving wheel 41 and the driven wheel 42 are both disposed between the protective box 50 and the connecting seat 11. The drive mechanism 20 is installed on the protective box 50 and is located on both sides of the protective box 50, respectively, along with the driving wheel 41. The connecting seat 11 provides support for the driving wheel 41 and the driven wheel 42. The protective box 50 and the connecting seat 11 cooperate to prevent the transmission of the driving wheel 41 and the driven wheel 42 from being affected by the external environment, and can also prevent users from being pinched when they put their hands between the driving wheel 41 and the driven wheel 42. Simultaneously, the protective box 50 provides support for the drive mechanism 20 and facilitates the assembly of the air conditioning device 100. The protective box 50 can be made of metal or a relatively hard plastic; no specific limitation is made here.

[0055] It should be noted that one end of the two transmission components 43 is connected to the first transmission column 411 and the second transmission column 421 respectively, and both are located between the protective box 50 and the connecting seat 11. The protective box 50 and the connecting seat 11 cooperate to limit the transmission component 43 in the axial direction of the drive wheel 41.

[0056] Please see Figures 11 to 12 In some embodiments, the protective box 50 is provided with a limiting part 51 on the side facing the driven wheel 42. The limiting part 51 passes through the driven wheel 42 and limits the driven wheel 42 in the rotational axis. In this way, the limiting part 51 limits the driven member 42, thereby preventing the driven wheel 42 from sliding off the driving wheel 41 in the axial direction, which would prevent the fan blade assembly 41 from swinging normally. At the same time, the driven wheel 42 rotates around the limiting part 51, so that the limiting part 51 limits the driven wheel 42 in the radial direction, thereby preventing the driven wheel 42 from sliding off the driving wheel 41 in the radial direction, which would prevent the fan blade assembly 41 from swinging normally.

[0057] Please see Figures 11 to 12 For example, the driven wheel 42 has an annular protrusion 422 protruding from the outer periphery of one end where the second transmission post 421 is located, and the driving wheel 41 has an annular groove 412 recessed from the outer periphery of one end where the first transmission post 411 is located. The annular protrusion 422 extends into the annular groove 412 and cooperates with the protective box 50 to limit the driving wheel 41's rotational axis. In this way, the annular protrusion 422 cooperates with the protective box 50 to limit the driving wheel 41's rotational axis, thereby ensuring that the driving wheel 41 and the driven wheel 42 mesh, and thus the driving wheel 41 can stably drive the driven wheel 42 to rotate, ensuring that the driving wheel 41 and the driven wheel 42 can smoothly drive the two sets of fan blade assemblies 41 to swing.

[0058] like Figure 2As 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.

[0059] like Figure 11 As shown, in some embodiments, the bottom of the limiting groove 11a is further recessed with an abutment groove 11b, and the second transmission post 421 extends into the abutment groove 11b, with its outer peripheral wall abutting against the groove wall of the abutment groove 11b. By abutting against the groove wall of the abutment groove 11b with the second limiting post, the driven wheel 42 is further limited radially. At this time, the end of the transmission member 43 that is connected to the second limiting post is located between the bottom of the limiting groove 11a and the protective box 50, which can limit the transmission member 43 axially against the driven wheel 42, preventing the transmission member 43 from disengaging from the second limiting post.

[0060] 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 of the air conditioning unit 100 between various states. 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-hand oscillation. Users can experience the wind effect in this paused state. If the user wishes to change the wind direction or switch modes, simply pressing the "Swing-Pause" button again rotates the drive mechanism 20, driving the eccentric wheel and transmission mechanism 40, causing the guide vanes 311 to switch from the current paused position to either a converging or dispersing oscillation state, thus entering the switching state. Pressing the "Swing-Pause" button again pauses the tower fan again. This button design allows users to flexibly switch between continuous oscillation and fixed-point airflow.

[0061] 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 to rotate, the tower fan will undergo a cycle of swing state switching. It can start in a parallel swing state. It should be noted that while the starting state of this cycle can be parallel swing, this is not necessarily the starting point. It actually depends on the state at which the fan was paused during the last shutdown. Taking the drive wheel 41 and driven wheel 42 having the same number of teeth as an example, when the drive mechanism 20 continues to rotate, after rotating 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° rotations), the tower fan will switch from the dispersed swing state back to the parallel swing state. After rotating approximately 90° (a total of approximately 270°), the tower fan will switch to a convergent 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, i.e., a cycle of parallel swing -> dispersed swing -> parallel swing -> convergent swing -> parallel swing.

[0062] 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 will begin to drive the two transmission components 43 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.

[0063] like Figure 2 and Figure 13As shown, in some embodiments, the transmission member 43 has a guide groove 43a, and an eccentric wheel is disposed within the guide groove 43a. The guide groove 43a restricts the rotation of the eccentric wheel. The guide groove 43a has a length direction and a width direction. In this embodiment, the length direction is in the same direction as the front-rear direction of the tower fan, and the width direction is in the same direction as the left-right direction of the tower fan. Understandably, the motion trajectory of the eccentric wheel can be decomposed into two components along the length direction and the width direction of the guide groove 43a. The guide groove 43a has a first sidewall 43a1 and a second sidewall 43a2 that are opposite and parallel to each other along the width direction. Both the first sidewall 43a1 and the second sidewall 43a2 extend along the length direction, and both the first sidewall 43a1 and the second sidewall 43a2 slide in contact with the outer wall of the eccentric wheel. This allows the eccentric wheel to slide freely relative to each other along the length direction of the guide groove 43a. This means that the component along the length of the eccentric wheel's trajectory mainly manifests as the positional change of the eccentric wheel within the guide groove 43a, rather than directly transmitting as a displacement of the entire transmission component 43 along that direction (the front-to-back direction of the tower fan). When the eccentric wheel's movement generates a displacement component along the width direction, due to the obstruction of the first sidewall 43a1 and the second sidewall 43a2 (a small displacement under sliding fit), a contact force (normal force) is generated between it and the first sidewall 43a1 or the second sidewall 43a2. This force acts on the first sidewall 43a1 or the second sidewall 43a2 of the transmission component 43, driving the transmission component 43 to generate displacement in the width direction (the left-to-right direction of the tower fan).

[0064] like Figure 13 As shown, in this embodiment, the transmission component 43 is configured as a flat plate structure. The transmission component 43 has a connecting protrusion 433. The connecting protrusion 433 has a guide groove 43a extending through it in the direction away from the drive wheel 41. This increases the contact area between the guide grooves 43a of the two transmission components 43 and the first transmission column 411 and the second transmission column 421, respectively. This allows the first transmission column 411 and the second transmission column 421 to better drive the transmission component 43. At the same time, the connecting protrusion 433 can increase the thickness of the transmission component 43, thereby enhancing the strength of the transmission component 43 and improving its service life.

[0065] Specifically, the transmission component 43 includes a transmission part connected to the fan blade assembly 31 and a drive part connected to the first transmission column 411 or the second transmission column 421. The drive part is provided with a connecting protrusion 433 and a guide groove 43a. The connecting protrusion 433 of one transmission component 43 protrudes from the surface of the corresponding drive part close to the drive assembly in the axial direction of the drive wheel 41, and the connecting protrusion 433 of the other transmission component 43 protrudes from the surface of the corresponding drive part away from the drive assembly in the axial direction of the drive wheel 41. In this way, the transmission parts of the two transmission components 43 can be spaced apart in the axial direction of the drive wheel 41, thereby avoiding interference between the drive parts of the two transmission components 43 during the movement of the transmission component 43.

[0066] like Figure 2 As shown, in some embodiments, each fan blade assembly 31 includes multiple spaced-apart guide vanes 311. One of the transmission member 43 and the guide vanes 311 is provided with a retaining post 3111, and the other is provided with a retaining groove 43b. The retaining post 3111 is disposed within the retaining groove 43b, and there is a certain gap between the retaining post 3111 and the retaining groove 43b, allowing the guide vane 311 to deflect around its own pivot point when subjected to the force of the transmission member 43. That is, the retaining groove 43b does not tightly clamp the retaining post 3111, but allows relative rotation. Through the cooperation of the retaining post 3111 and the retaining groove 43b, the guide vane 311 can be driven by the transmission member 43 to deflect. The retaining groove 43b and the retaining post 3111 connect the guide vane 311 to the transmission member 43, ensuring that the guide vane 311 can move with the movement of the transmission member 43.

[0067] like Figure 2 and Figure 13 As shown, in this embodiment, the transmission component 43 is provided with a retaining groove 43b, the opening of which faces opposite to the opening of the guide groove 43a. The guide vane 311 is provided with a retaining post 3111. Understandably, as described above, the retaining post 3111 and the retaining groove 43b are located at the mounting opening 10d. To facilitate connection with the retaining groove 43b, 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 43b 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.

[0068] 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 43. The driving components of the transmission component 43 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 43 may also be configured as a latch 3111, and the air guide blade 311 is provided with a latch groove 43b. The principle is similar to the above configuration, and will not be described again here.

[0069] Furthermore, such as Figure 13 As shown, the transmission component 43 includes a main body 431 and a plurality of fasteners 432 connected to the outer edge of the main body 431. The main body 431 has a guide groove 43a. The plurality of fasteners 432 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 432 on a transmission component 43.

[0070] Fastener 432 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 43b. The fastening post 3111 can deflect along the groove wall of the fastening post 43b 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.

[0071] 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 43 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.

[0072] 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.

[0073] To solve the above problems, such as Figure 2 and Figure 14 As shown, in some embodiments, the housing 10 further includes a support member 14 connected to the frame 12 and arranged along the direction of the plurality of 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 a plurality of support holes 14a spaced apart along the width direction.

[0074] like Figure 2As shown, 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 disposed 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 uniform.

[0075] Furthermore, such as Figure 2 As shown, 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.

[0076] like Figure 14 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.

[0077] 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.

[0078] 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.

[0079] 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.
