Description

Technical Field

[0001] This application relates to the field of swing device 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

[0019] 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.

[0020] 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.

[0021] 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.

[0022] Please see Figures 1 to 2 A tower fan is an electric fan with a slender shape, generally cylindrical or rectangular in shape. It includes a fan wheel, a housing 10, an air guide mechanism 30, and a drive mechanism 20. The housing 10 can be composed of a main housing and an air outlet frame. The main housing is the main body 3121 of the tower fan and has an internal air duct. The air outlet frame is connected to the main housing and can be securely connected to the main housing by screws. The main housing 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, and the fan wheel is located inside the main housing. 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.

[0023] 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.

[0024] 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 swing states of the two sets of fan blade assemblies 31, thereby achieving multiple air delivery modes. The drive mechanism 20 is connected to the housing 10 and is the power source of the air guiding mechanism 30. The drive mechanism 20 includes two drive members 21, which are responsible for providing rotational power to the swing of the two sets of fan blade assemblies 31, so that the two sets of fan blade assemblies 31 can swing.

[0025] Please see Figures 3 to 7 By using two driving components 21 to drive two sets of fan blade assemblies 31 respectively, the movement of the two sets of fan blade assemblies 31 can be relatively independent, achieving non-synchronous movement. This is the basis for realizing multiple air guiding states. Specifically, the two driving components 21 can drive the two sets of fan blade assemblies 31 to swing in the same or opposite directions to switch different working states, thereby enabling the two sets of fan blade assemblies 31 to achieve multiple different air guiding states.

[0026] Understandably, the output shaft of the drive unit 21 can rotate in a first direction and also in a second direction, and the first and second directions are opposite, that is, the output shaft of the drive unit 21 can rotate clockwise and counterclockwise. The two drive units 21 can be started individually to make one set of fan blade assemblies 31 swing while the other set of fan blade assemblies 31 remains stationary. The two drive units 21 can also be started simultaneously to make both sets of fan blade assemblies 31 swing at the same time.

[0027] When both drive components 21 are activated simultaneously, the oscillation state of the two sets of fan blade assemblies 31 can be divided into a first state and a second state. Please refer to [link / reference]. Figures 4 to 5 The first state can be configured as follows: the output shafts of the two drive components 21 rotate in the same direction, causing the two sets of fan blade assemblies 31 to swing towards the same side. Please refer to [link / reference]. Figures 6 to 7 The second state can be configured such that the output shafts of the two drive components 21 rotate in opposite directions, causing the two sets of fan blade assemblies 31 to swing in opposite directions, so that the two sets of fan blade assemblies 31 are roughly brought together, i.e., the wind converges (e.g., Figure 6 As shown), or they sway in opposite directions, i.e., dispersed winds (such as... Figure 7 As shown in the diagram, converging air can direct airflow to a designated area, suitable for scenarios requiring strong airflow. Decentralizing air can distribute airflow over a wider area, allowing users in different locations within the space to experience a cool breeze.

[0028] Please see Figure 1 Two sets of fan blade assemblies 31 are spaced apart along the arrangement direction. The arrangement direction can be the width direction, that is, the two sets of fan blade assemblies 31 swing to guide the wind blown by the wind wheel to the left or right. The arrangement direction can also be the height direction, that is, the two sets of fan blade assemblies 31 swing to guide the wind blown by the wind wheel to the up or down.

[0029] In this embodiment, the two sets of fan blade assemblies 31 can swing in different directions under the drive of the two drive members 21, thereby increasing the diversity of the swing state of the air conditioning device 100. At the same time, the drive member 21 is directly connected to the fan blade assembly 31 to reduce the torque and reduce the loss, thereby reducing the energy consumption of the air conditioning device 100.

[0030] 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 rotation axis of the fan blade assembly 31 is parallel to 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.

[0031] Each fan blade assembly 31 in this embodiment is provided with three guide vanes 311. The guide vanes 311 are arranged at intervals along the arrangement direction, 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 airflow, air feel and other factors to achieve a better overall air supply effect.

[0032] In the second state, the two sets of fan blade assemblies 31 have a convergent swing mode (such as... Figure 6 ), decentralized swing mode (such as Figure 7 ) and the same-direction swing mode (such as Figure 3 ).

[0033] In both the first and second states of the same-direction swing mode, the guide vanes 311 extend approximately along the front-to-back direction of the tower fan. Specifically, in the same-direction swing mode, the guide vanes 311 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 a region approximately between 30° to the left and 30° to the right.

[0034] The initial settings during tower fan production will be adjusted to the first state of airflow. It's important to note that this doesn't refer to a specific sub-state within the first state, but rather a general state for unidirectional airflow. This state was chosen as the factory default primarily based on market research and user habits; most customers prefer the first state where multiple guide vanes 311 are aligned in the same direction.

[0035] In actual use, after receiving the wind direction oscillation signal sent by the user, the tower fan controls the drive unit 21 to work. It should be noted that the user can send the wind direction oscillation signal to the tower fan through voice, wireless signal, buttons set on the tower fan or remote control.

[0036] For example, when the tower fan starts and receives a wind direction oscillation signal, it enters the first state. Both drive components 21 simultaneously drive the corresponding guide vanes 311 to oscillate 30° to the left, then change the rotation direction of the output shaft. That is, the drive component 21 drives the corresponding guide vanes 311 to oscillate to the right until the corresponding guide vanes 311 oscillate 30° to the right, then change the rotation direction of the output shaft. That is, the drive component 21 drives the corresponding guide vanes 311 to oscillate to the left. This process repeats, achieving the same reciprocating oscillation of the two sets of fan blade assemblies 31. It should be noted that the angle by which the guide vanes 311 rotate from oscillating 30° to the left to oscillating 30° to the right is 60°.

[0037] For example, the tower fan may enter a first state after receiving a wind direction oscillation signal after startup, then enter a second state after receiving another wind direction oscillation signal, then enter a third state after receiving another wind direction oscillation signal, and then enter the first state again after receiving another wind direction oscillation signal, and so on in a cycle.

[0038] When the tower fan receives a wind direction oscillation signal in the first state, it will enter the second state. One of the two drive components 21 changes the rotation direction of its output shaft so that the rotation directions of the output shafts of the two drive components 21 are opposite. As a result, the two drive components 21 drive the corresponding air guide blades 311 to rotate in opposite directions to achieve wind dispersion to both sides, or the two drive components 21 drive the corresponding air guide blades 311 to rotate in opposite directions to achieve wind concentration in the middle. For example, when the tower fan enters the second state, one drive unit 21 drives the corresponding air guide blade 311 to swing 30° to the left and then changes the rotation direction of the output shaft, that is, the drive unit 21 drives the corresponding air guide blade 311 to start swinging to the right. The other drive unit 21 drives the corresponding air guide blade 311 to swing 30° to the right and then changes the rotation direction of the output shaft, that is, the drive unit 21 drives the corresponding air guide blade 311 to start swinging to the left. Subsequently, after the two air guide blades 311 rotate by an angle of 60°, the drive unit 21 connected to the two air guide blades 311 changes the rotation direction of the output shaft, so that the two air guide blades 311 change the swing direction.

[0039] For example, after receiving a wind direction oscillation signal in the first state of the tower fan, the two drive units 21 first drive the corresponding guide vanes 311 to oscillate in opposite directions to 30° before reciprocating. It can be understood that the two guide vanes 311 oscillate in the same direction in the first state. This means that when the tower fan receives the wind direction oscillation signal, one of the two guide vanes 311 changes its oscillation direction, resulting in different travel distances required for the two guide vanes 311 to oscillate to 30° in their respective directions. At this time, the drive unit 21 corresponding to the guide vane 311 that oscillates to 30° first stops working until the other guide vane 311 oscillates to 30°, at which point the drive unit 21 restarts. During this time, the two guide vanes 311 only switch back and forth between a converging state and a dispersing state. That is, a cyclical switching between unidirectional central wind guiding mode → dispersed oscillation → unidirectional central wind guiding mode → converging oscillation → unidirectional central wind guiding mode.

[0040] When the tower fan receives a wind direction oscillation signal in the second state, it enters the third state. The two drive components 21 stop working, causing the two guide vanes 311 to stop oscillating. For example, after receiving the wind direction oscillation signal in the third state, the two drive components 21 first drive the corresponding guide vanes 311 to oscillate in opposite directions to 30° before reciprocating. It can be understood that when the two guide vanes 311 are paused in the second state, they oscillate in opposite directions. This means that when the tower fan receives the wind direction oscillation signal, one of the two guide vanes 311 changes its oscillation direction, resulting in different travel distances required for the two guide vanes 311 to oscillate in the same direction to 30°. At this point, the drive component 21 corresponding to the guide vane 311 that oscillates to 30° first stops working until the other guide vane 311 oscillates to 30°, at which point the drive component 21 restarts. At this point, the oscillation angles of the two guide vanes 311 during the oscillation process are the same.

[0041] For example, the tower fan may enter a first state after receiving a wind direction oscillation signal after startup, then enter a third state after receiving another wind direction oscillation signal, then enter a second state after receiving another wind direction oscillation signal, then enter a third state after receiving another wind direction oscillation signal, and so on in a cycle.

[0042] Please see Figure 2 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.

[0043] Please see Figures 8 to 9 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.

[0044] The positions of the two sets of snap-fit ​​structures 13 are related to the arrangement of the air guide mechanism 30. If the air guide blade 311 extends along the height direction of the housing 10, the two sets of snap-fit ​​structures 13 are arranged opposite each other along the height direction of the housing 10. If the air guide blade 311 extends along the width direction of the housing 10, the two sets of snap-fit ​​structures 13 are arranged opposite each other along the width direction of the housing 10.

[0045] Please see Figure 9 The latching structure 13 includes multiple elastic latches 131, each corresponding to a plurality of rotating shafts 3113. Each elastic latch 131 has a slot 131a, within which the rotating shaft 3113 is engaged and can rotate, allowing the guide vane 311 to deflect around the rotating shafts 3113 at both ends. The slot 131a provided by the elastic latch 131 offers a rotating interface, forming the basis for achieving dynamic effects such as blade opening and closing, and oscillation.

[0046] Specifically, the elastic buckle 131 includes a first buckle portion 312a and a second buckle portion 312a. The first buckle portion 312a and the second buckle portion 312a are arranged opposite to each other and define a slot 131a. The first buckle portion 312a and the second buckle portion 312a 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.

[0047] Please see Figure 2 In some embodiments, each set of fan blades 31 includes multiple guide vanes 311 and a connector 312. The multiple guide vanes 311 are rotatably connected to the housing 10, and the connector 312 is drive-connected to the guide vanes 311. The drive member 21 is drive-connected to a guide vane 311 to drive the corresponding guide vane 311 to swing. The guide vane 311 connected to the drive member 21 drives the remaining guide vanes 311 to swing through the connector 312.

[0048] With this configuration, the drive unit 21 drives the corresponding air guide blade 311 to swing, the swing of the air guide blade 311 drives the connecting member 312 to move, and the movement of the connecting member 312 will drive the remaining air guide blades 311 to swing, thereby realizing that one drive unit 21 drives multiple air guide blades 311 to swing, reducing the production cost of the air conditioning equipment 100.

[0049] The drive unit 21 can be connected to any one of the guide vanes 311. For example, the drive unit 21 is connected to the guide vane 311 located in the middle of a set of fan blade assemblies 31. This configuration makes the torque of the drive unit 21 the same as that of the guide vanes 311 located on both sides, so that the drive unit 21 can drive multiple guide vanes 311 to rotate with lower power, thereby extending the service life of the drive unit 21.

[0050] like Figure 2 and Figure 10 As shown, in some embodiments, each fan blade assembly 31 includes multiple spaced-apart guide vanes 311. One of the connector 312 and the guide vane 311 is provided with a latching post 3111, and the other of the connector 312 and the guide vane 311 is provided with a latching groove 312b. The latching post 3111 is disposed within the latching groove 312b, and there is a certain gap between the latching post 3111 and the latching groove 312b, allowing the guide vane 311 to deflect around its own pivot point when subjected to the force of the connector 312. That is, the latching groove 312b does not tightly clamp the latching post 3111, but allows relative rotation. Through the cooperation of the latching post 3111 and the latching groove 312b, the guide vane 311 can be driven by the connector 312 to deflect. The latching groove 312b and the latching post 3111 connect the guide vane 311 to the connector 312, ensuring that the guide vane 311 can move with the movement of the connector 312.

[0051] Please see Figure 2 and Figure 10 In this embodiment, the connector 312 is provided with a retaining groove 312b, and the air guide vane 311 is provided with a retaining post 3111. The central axis of the retaining post 3111 extends in the vertical direction. When the retaining groove 312b moves to the left, the right sidewall of the groove will press against the retaining post 3111. The retaining post 3111 is part of the air guide vane 311. This leftward force acts on the retaining post 3111, which is equivalent to acting on the air guide vane 311 near the pivot point, applying a leftward thrust. This leftward thrust generates a torque relative to the pivot point of the air guide vane 311. According to the lever principle, this torque will cause the air guide vane 311 to rotate around its pivot point, and the air guide vane 311 will deflect to the right.

[0052] like Figure 2As shown, it should be noted that the positions of the corresponding fasteners 3111 of the guide vanes 311 of the two sets of fan blade assemblies 31 are not the same in the height direction. The fasteners 3111 need to be connected to the connectors 312. The connectors 312 that drive the two fasteners 3111 are not located on the same horizontal line, but have a certain height difference, so that the movement trajectories of the two connectors 312 are staggered in the height direction, which can prevent them from colliding or interfering with each other during movement.

[0053] Understandably, in other embodiments, the connector 312 may also be configured as a snap post 3111, and the air guide blade 311 is provided with a snap groove 312b. The principle is similar to the above configuration, and will not be described again here.

[0054] like Figure 10 As shown, the connector 312 further includes a main body 3121 and a plurality of fasteners 3122 connected to the outer edge of the main body 3121. The plurality of fasteners 3122 are configured one-to-one 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 wind vane 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 3122 on a connector 312.

[0055] The fastener 3122 includes two fastening portions 312a with an arc-shaped clamping structure. The arc-shaped clamping structure provides more uniform contact and support. The two fastening portions 312a define a fastening groove 312b. The fastening post 3111 can deflect along the groove wall of the fastening groove 312b 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.

[0056] 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 vane 311 into the corresponding position set on the connector 312 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.

[0057] Please see Figure 3In some embodiments, the air outlet 10a is divided into a first region 10a1 and a second region 10a2 in the arrangement direction of the two sets of fan blade assemblies 31, with the two sets of fan blade assemblies 31 located in the first region 10a1 and the second region 10a2 respectively. This arrangement ensures that the division of the first region 10a1 and the second region 10a2 prevents the airflow from the two sets of fan blade assemblies 31 from interfering with each other when in a dispersed state, thus better dispersing the airflow and allowing it to reach a wider area, enabling users in different locations within the space to better experience the cool breeze.

[0058] Please see Figure 4 In some embodiments, the housing 10 has a first limiting group 17 and two second limiting portions 18. The first limiting group 17 is located between the two sets of fan blade assemblies 31 and is used to limit the two connecting members 312 in a direction that brings them closer together. The two second limiting portions 18 are respectively located on the side of the two connecting members 312 that are farther apart from each other and are respectively used to limit the two connecting members 312 in a direction that keeps them farther apart from each other. With this configuration, when the fan blade assembly 31 swings away from the other fan blade assembly 31 to a specified angle (the aforementioned 30° sway), the connecting member 312 connected to the fan blade assembly 31 abuts against the second limiting portions 18 to prevent the fan blade assembly 31 from swinging excessively and to facilitate the identification of the fan blade assembly 31 swinging to the specified angle. When the fan blade assembly 31 swings closer to the other fan blade assembly 31 to a specified angle (the aforementioned 30° sway), the connecting member 312 connected to the fan blade assembly 31 abuts against the first limiting group 17 to prevent the fan blade assembly 31 from swinging excessively and to facilitate the identification of the fan blade assembly 31 swinging to the specified angle.

[0059] The first limiting group 17 can be composed of a single limiting part, which simultaneously limits two sets of fan blade assemblies 31. Alternatively, the first limiting group 17 can be composed of two limiting parts, each limiting one set of fan blade assemblies 31. Exemplarily, two connecting members 312 are spaced apart along the rotational axis of the guide vane 311. The first limiting group 17 includes two first limiting parts 171, spaced apart along both the rotational axis and the arrangement direction. The first limiting parts 171 abut against and limit the connecting members 312 that are away from themselves in the arrangement direction. This allows for a larger swing amplitude of the two sets of fan blade assemblies 31, thereby improving the practicality of the tower fan. It is understood that when a connecting member 312 abuts against a corresponding first limiting part 171, the connecting member 312 and the other first limiting part 171 are spaced apart along the rotational axis of the guide vane 311, and their projections along the rotational axis of the guide vane 311 at least partially overlap.

[0060] Please see Figure 10In some embodiments, the cross-sectional area of ​​the connector 312 increases toward the corresponding first limiting portion 171. This arrangement increases the contact area between the connector 312 and the first limiting portion 171, thereby facilitating contact between the connector 312 and the first limiting portion 171, and allowing the first limiting portion 171 to better limit the connector 312.

[0061] Please see Figure 9 In some embodiments, the housing 10 has a clearance hole 10g, and two first limiting portions 171 are respectively disposed on the two opposite walls of the clearance hole 10g in the rotational axis. The two connecting members 312 are at least partially located inside the clearance hole 10g and abut against and limit the corresponding first limiting portions 171. This arrangement can make full use of the space of the housing 10 in the front-rear direction, thereby reducing the thickness of the tower fan in the front-rear direction, and thus reducing the volume of the tower fan, making it easier for users to use the tower fan.

[0062] like Figure 2 as well as Figure 11 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.

[0063] 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 plus one support point), instead of being concentrated at both ends, thus making the force on the guide blade 311 more even.

[0064] like Figure 8 As shown, the housing 10 further includes two receiving slots 10f, which are arranged opposite to each other along the arrangement direction of the plurality of 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.

[0065] like Figure 11As 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.

[0066] The receiving groove 10f and the clamping channel 10e provide an 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 limited, 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.

[0067] like Figure 8 As shown, in some embodiments, the housing 10 also 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 the width direction, and the plurality of second protective ribs 16 are arranged at intervals along the height direction. Understandably, the first protective ribs 15 extend along the height direction, while the second protective ribs 16 extend along the width direction to form a hollow mesh. The purpose of providing 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.

[0068] 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.

[0069] In some embodiments, the air conditioning device 100 further includes a control module disposed on the top of the housing 10 and electrically connected to two drive members 21 for controlling the two drive members 21 to drive two sets of fan blade assemblies 31 to rotate in the same or opposite directions. With this configuration, the user only needs to send commands to the control module to control the two sets of fan blade assemblies 31 to swing in the specified directions, thus facilitating user operation of the air conditioning device 100. The control module and the two drive members 21 can be electrically connected via wires or wirelessly via Bluetooth, WIFI, or other means.
