[0001] This application claims priority to a Chinese patent application filed on October 28, 2024, with the China National Intellectual Property Office, and application number

[0002] The priority of the Chinese patent application No. 202411514814.7, with the title of "Air guide assembly and air treatment device", filed on October 28, 2024, is hereby claimed, and its entire content is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the technical field of air treatment devices, in particular to an air guide assembly and an air treatment device. BACKGROUND

[0004] Air treatment devices, such as air conditioning devices, etc., usually include an air outlet and an air guide plate arranged at the air outlet. The air guide plate is rotationally connected at the air outlet, and by changing the angle at which the air guide plate is opened relative to the air outlet, the air supply direction of the air outlet is changed.

[0005] However, the above-mentioned way of adjusting the air supply direction causes the air supply area of the air treatment device to be relatively limited. SUMMARY

[0006] The present application provides an air guide assembly and an air treatment device. The air guide assembly can flexibly adjust the air supply angle of the air treatment device, and expand the air supply coverage area of the air treatment device. Moreover, the driving mode of the air guide assembly is simpler, which is conducive to saving space and reducing energy consumption.

[0007] In one aspect, the present application provides an air guide assembly installed at an air outlet of an air treatment device. The air guide assembly includes an adjustment assembly and a driving assembly. The driving assembly can drive the adjustment assembly to move. The driving assembly can drive each air guide blade on the bearing plate to rotate, and by changing the deflection angle of the air guide blade, the air supply angle is adjusted. Moreover, the driving assembly can also drive the bearing plate to swing relative to the air outlet, and by changing the deflection angle of the bearing plate, the air supply angle is adjusted. In this way, the air supply angle of the air treatment device can be flexibly adjusted, the air supply coverage area of the air treatment device is expanded, large-area area air supply can be achieved, and blind areas of air supply can be avoided, the temperature uniformity in the room is improved, and the comfort in the room is improved.

[0008] The air guide assembly provided by the present application is installed at the air outlet of the air treatment device. The air guide assembly includes an adjustment assembly and a driving assembly. The driving assembly can drive the adjustment assembly to move. The driving assembly can drive each air guide blade on the bearing plate to rotate, and by changing the deflection angle of the air guide blade, the air supply angle is adjusted. Moreover, the driving assembly can also drive the bearing plate to swing relative to the air outlet, and by changing the deflection angle of the bearing plate, the air supply angle is adjusted. In this way, the air supply angle of the air treatment device can be flexibly adjusted, the air supply coverage area of the air treatment device is expanded, large-area area air supply can be achieved, and blind areas of air supply can be avoided, the temperature uniformity in the room is improved, and the comfort in the room is improved.

[0009] Moreover, only one driving motor is used to drive the rotation of the guide vanes and the swing of the carrier plate, thus simplifying the driving mode of the adjusting assembly. The number of driving motors is reduced to the greatest extent, the structure of the driving assembly is simpler, the driving assembly occupies less space and weighs less. The layout space of the air handling equipment can be saved, the arrangement of other components is facilitated, and the energy consumption of the air handling equipment can be saved.

[0010] In a possible implementation, the transmission member is a gear set, which drives the swing of the carrier plate to change the included angle between the carrier plate and the length direction of the air outlet.

[0011] In this way, the gear transmission is used to realize the transmission between the driving motor and the carrier plate. The gear set can drive the swing of the carrier plate to change the included angle between the carrier plate and the length direction of the air outlet. Moreover, the gear set is compact in size, and can reduce the occupied space of the driving assembly. In addition, the gear set is a precise transmission mode, which is high in transmission efficiency and transmission precision, and the guide vane assembly is high in precision of adjusting the air supply angle.

[0012] In a possible implementation, the gear set includes: a first gear pair in transmission connection with the driving motor; and a second gear pair in transmission connection between the first gear pair and the carrier plate and driving the swing of the carrier plate, wherein the driving motor or the first gear pair drives the swing of the guide vanes.

[0013] In this way, the driving motor or the first gear pair drives the continuous rotation of the guide vanes during the continuous operation of the driving motor. Moreover, the power of the driving motor is transmitted to the second gear pair through the first gear pair, and the transmission design of the first gear pair and the second gear pair can realize the transmission of power from the first gear pair to the second gear pair or the non-transmission of power from the first gear pair to the second gear pair, so that the second gear pair can drive the movement of the carrier plate or keep the carrier plate stationary.

[0014] In a possible implementation, the second gear pair is located on the side of the first gear pair close to the carrier plate.

[0015] In this way, the first gear pair and the second gear pair are stacked to facilitate the transmission of power therebetween. The second gear pair is closer to the carrier plate, facilitating the connection between the second gear pair and the carrier plate. Moreover, the gear set is smaller in size, and the driving assembly occupies less space as a whole.

[0016] In a possible implementation, the first gear pair includes a driving wheel connected with the output shaft of the driving motor, and the second gear pair includes a first transmission wheel arranged on the side of the driving wheel close to the carrier plate. The first transmission wheel is in transmission connection with the driving wheel, and the carrier plate is in transmission connection with the first transmission wheel.

[0017] After the driving motor is started, the driving motor can drive the driving wheel to continuously rotate, so as to drive the air guide blade to continuously rotate. In the process of rotation of the driving wheel, the driving wheel can drive the first transmission wheel to rotate to drive the bearing plate to swing, or the driving wheel can not drive the first transmission wheel, and the first transmission wheel remains stationary, so that the bearing plate remains stationary.

[0018] In a possible implementation, the movement mode of the adjustment assembly driven by the driving assembly includes a first movement mode and a second movement mode; when the driving wheel drives the first transmission wheel to synchronously rotate, the air guide blade swings and the bearing plate moves, and the adjustment assembly is in the first movement mode; when the driving wheel rotates and the first transmission wheel is stationary, the air guide blade swings and the bearing plate is stationary, and the adjustment assembly is in the second movement mode.

[0019] In this way, through the transmission cooperation of the driving wheel and the first transmission wheel, the air guide blade can continuously rotate after the driving motor is started, and the bearing plate can swing or remain stationary. The driving assembly can drive the adjustment assembly to flexibly move to meet the needs of different air supply angles. According to the air supply angle requirement of the user, the driving assembly drives the adjustment assembly to move in the first movement mode or in the second movement mode, so that the deflection angle of the air guide blade relative to the initial position reaches the air supply angle.

[0020] In a possible implementation, the first transmission wheel is partially overlapped with the driving wheel, the driving wheel is provided with a transmission rod on the side facing the first transmission wheel, the first transmission wheel is provided with a transmission groove, and the transmission groove is communicated to the side wall of the first transmission wheel; when the transmission rod enters the transmission groove and slides along the transmission groove, the driving wheel drives the first transmission wheel to synchronously rotate; when the transmission rod is separated from the transmission groove, the first transmission wheel is stationary when the driving wheel rotates.

[0021] In this way, in the process of rotation of the driving wheel driven by the driving motor, the transmission rod on the driving wheel performs a circular motion. When the transmission rod on the driving wheel rotates to the notch position of the transmission groove on the first transmission wheel, with the continuous rotation of the driving wheel, the transmission rod will enter the transmission groove and slide along the transmission groove. During this period, the first transmission wheel will synchronously rotate with the driving wheel, so that the adjustment assembly moves in the first movement mode. When the transmission rod is separated from the transmission groove, the first transmission wheel will stop rotating and stay at the current position, so that the adjustment assembly moves in the second movement mode.

[0022] In a possible implementation, the transmission groove extends along the radial direction of the first transmission wheel.

[0023] Thus, in the process of driving the first transmission wheel to rotate by the driving wheel, the movement track of the transmission groove always matches the circumferential track of the transmission rod movement. It can ensure the transmission rod to smoothly slide along the transmission groove, and the transmission rod and the first transmission wheel will not interfere or be stuck, and the driving wheel can smoothly drive the first transmission wheel to rotate.

[0024] In a possible implementation, the first gear pair further comprises a first driven wheel, the first driven wheel is coaxially arranged on the side of the driving wheel close to the bearing plate, and the first driven wheel and the first transmission wheel do not interfere with each other; wherein the driving motor or the first driven wheel drives each guide vane to swing.

[0025] Thus, on the basis of the first transmission wheel and the driving wheel only partially overlapping, the first driven wheel makes the gear set have more overlapping parts, and the first driven wheel increases the counterweight of the gear set, and the stability and reliability of the gear set are higher. Moreover, the first driven wheel and the first transmission wheel do not overlap and are not interfered with each other, and will not affect the rotation of the first transmission wheel.

[0026] In a possible implementation, the outer peripheral wall of the first transmission wheel has at least one concave arc surface, the concave arc surface matches the outer cylindrical surface of the first driven wheel, and the outer cylindrical surface of the first driven wheel slides along the concave arc surface.

[0027] Thus, in the process of driving the first transmission wheel to rotate by the driving wheel, the outer cylindrical surface of the first driven wheel slides along the concave arc surface of the first transmission wheel. The first driven wheel and the first transmission wheel do not interfere with each other, and do not affect the rotation of the first transmission wheel. Moreover, the first driven wheel and the second transmission wheel have mutually matched friction surfaces between them, and a certain friction force is generated between them, which can make the movement of the first transmission wheel more stable and reliable.

[0028] In a possible implementation, the outer peripheral wall of the first transmission wheel has two or more concave arc surfaces, and each concave arc surface is uniformly and spaced apart along the circumference of the first transmission wheel.

[0029] Thus, the profile of the first transmission wheel is more regular and symmetrical. The transmission groove can be arranged corresponding to any concave arc surface, which reduces the processing difficulty of the first transmission wheel and improves the processing efficiency of the first transmission wheel. Moreover, the volume of the first transmission wheel protruding outside the driving wheel is smaller, and the overall operation reliability of the gear set is higher.

[0030] In a possible implementation, the outer peripheral wall of the first driven wheel is provided with a recess for avoiding the transmission rod of the driving wheel.

[0031] Thus, the transmission rod is located on the side of the recess for avoiding, so as to leave a certain space outside the transmission rod, and avoid interference with the cooperation between the transmission rod and the recess.

[0032] In a possible implementation, the avoiding recess is an arc-shaped recess, and the axis of the transmission rod is located on a radial line of the arc-shaped recess.

[0033] In this way, the first driven wheel can be positioned and installed by using the transmission rod. Moreover, the first driven wheel and the driving wheel are symmetrically arranged after assembly, and the appearance effect is better.

[0034] In a possible implementation, the second gear pair further includes a second driven wheel, which is coaxially arranged on the side of the first transmission wheel close to the bearing plate, and is in transmission connection with the bearing plate.

[0035] In this way, the second driven wheel is closer to the bearing plate, and the connection between the second gear pair and the bearing plate is facilitated. Moreover, the coaxially arranged second driven wheel rotates synchronously with the first transmission wheel, so that the bearing plate can be swung by the second gear pair, or the bearing plate is limited at the initial position or the limit position by the second gear pair, and the bearing plate remains stationary.

[0036] In a possible implementation, the second gear pair further includes a second transmission wheel, which is arranged on the side of the first driven wheel close to the bearing plate, and is in mesh with the second driven wheel, and the second transmission wheel is connected with the bearing plate.

[0037] The second transmission wheel can adjust the output rotation speed of the second gear pair, and the size of the second driven wheel can be selected according to the required swinging speed of the bearing plate, so that the rotation speed of the second transmission wheel is controlled within an appropriate range, and the bearing plate is swung stably. Moreover, the second transmission wheel is arranged above the first driven wheel, and the gravity center of the gear set as a whole can be adjusted, so that the gear set as a whole is more stable.

[0038] In a possible implementation, the outer diameter of the second transmission wheel is greater than the outer diameter of the second driven wheel.

[0039] In this way, the second transmission wheel can reduce the speed and increase the torque, so as to maintain the appropriate swinging speed of the bearing plate. Moreover, the torsion between the second transmission wheel and the bearing plate is greater, so that the movement of the bearing plate is more stable and reliable.

[0040] In a possible implementation, the air guide assembly includes an adjusting assembly; wherein the driving assembly is connected to the middle part of the adjusting assembly in the length direction, or the driving assembly is connected to one end of the adjusting assembly in the length direction.

[0041] The air guide blade of the adjusting assembly can be deflected relative to the bearing plate, the bearing plate can also be deflected relative to the air outlet, and one adjusting assembly also has a large enough air supply area, which can meet the requirements of a general indoor space.

[0042] The air guide assembly is more balanced in force and has higher reliability, and the deflection amplitudes of the adjustment assemblies to both sides are consistent, so that the air supply balance of the air guide assembly is better and the universality is higher. By connecting the driving assembly to one end of the adjustment assembly in the length direction, the adjustment assembly can extend more to the outside of the air outlet, and can almost be exposed to the outside, so that the interference and limitation of the air duct on the air guide vane can be avoided, and the air supply area of the adjustment assembly can be maximized.

[0043] In a possible implementation, the number of adjustment assemblies is two, and the two adjustment assemblies are arranged at intervals along the length direction of the air outlet; the number of driving assemblies is two, and the two driving assemblies are connected to the two adjustment assemblies respectively.

[0044] In this way, the two adjustment assemblies can supply air to different areas respectively, so that the air supply area of the air guide assembly and the air supply coverage area of the air handling device can be expanded. Moreover, the air supply areas of the two adjustment assemblies can be independently adjusted by the two driving assemblies driving the two adjustment assemblies respectively, so that the air supply area of the air guide assembly can be more flexibly regulated. Different environmental requirements can be met, and the airflow blown by the air guide assembly can be more fully utilized to avoid waste.

[0045] In a possible implementation, the two driving assemblies are symmetrically arranged with the center line between the two adjustment assemblies as the axis of symmetry.

[0046] In this way, the structure of the air guide assembly as a whole is better in symmetry, more balanced in force, better in stability and higher in reliability. Moreover, the coverage ranges of the air supply areas of the two adjustment assemblies are symmetrical, so that the universality of the air guide assembly is better. In addition, the installation positions of the two adjustment assemblies do not need to be distinguished during assembly of the air guide assembly, so that the assembly efficiency is higher.

[0047] In a possible implementation, the two driving assemblies are located at the ends of the two adjustment assemblies away from each other.

[0048] In this way, the adjustment assembly can extend more to the outside of the air outlet, and can almost be exposed to the outside. The interference and limitation of the air duct on the air guide vane can be avoided, and the air supply area of the adjustment assembly can be further expanded.

[0049] In a possible implementation, the adjustment assembly further comprises a linkage, all the air guide vanes are connected with the linkage, and the driving assembly drives all the air guide vanes to swing through the linkage.

[0050] When the driving assembly operates, the linkage can be driven to move. When the linkage moves, all the air guide vanes can be driven to swing synchronously.

[0051] In a possible implementation, the driving assembly is connected with one of the guide vanes, or the driving assembly is connected with the linkage.

[0052] In a possible implementation, the air guide assembly further comprises a control element, the control element being electrically connected with the driving assembly, and the control element controlling the driving assembly to operate.

[0053] In this way, the driving assembly is controlled to operate by the control element, the swing direction and the deflection angle of the guide vanes are controlled, the movement posture of the bearing plate is controlled, and the air supply direction and the air supply area of the adjustment assembly are precisely controlled.

[0054] Another aspect of the present application provides an air treatment device, comprising a device body and the air guide assembly as described above, the air guide assembly being arranged at an air outlet of the device body.

[0080] As described in the background, the conventional air conditioning equipment is provided with swingable air guide plates in the air duct to adjust the air supply angle. For example, the horizontal air guide plate swings up and down to realize up and down air sweeping, and the vertical air guide plate swings left and right to realize left and right air sweeping. The swing angle of all the air guide plates is uniformly regulated by the connecting rod, so as to adjust the overall air supply area of the air conditioning equipment.

[0081] However, the above-mentioned air supply area adjustment mode has a positive correlation between the area size of the air supply area and the area size of the air outlet. This will cause the air supply area of the air conditioning equipment to be relatively limited, and the air supply coverage area to be small, which cannot realize air supply in a large area. Moreover, since the air guide plate is located in the air duct and can only be deflected at the same rotation angle, a blind area will appear when the air supply angle is adjusted, which will cause the indoor temperature difference to be obvious and the comfort to be improved.

[0082] Therefore, the embodiments of the present application provide an air guide assembly and an air treatment equipment. The air guide assembly is installed at the air outlet of the air treatment equipment. The air guide assembly comprises an adjusting assembly and a driving assembly. The driving assembly can drive the adjusting assembly to move. The driving assembly can drive each air guide blade on the bearing plate to rotate, so as to adjust the air supply angle by changing the deflection angle of the air guide blade. Moreover, the driving assembly can also drive the bearing plate to swing relative to the air outlet, so as to adjust the air supply angle by changing the deflection angle of the bearing plate. In this way, the air supply angle of the air treatment equipment can be flexibly adjusted, the air supply coverage area of the air treatment equipment can be expanded, air supply in a large area can be realized, a blind area can be avoided, the temperature uniformity in the room can be improved, and the comfort in the room can be improved.

[0083] Moreover, only one driving motor and transmission member are used to drive each air guide blade on the bearing plate to rotate and drive the bearing plate to swing, which simplifies the driving mode of the adjusting assembly. The number of driving motors is reduced to the greatest extent, the structure of the driving assembly is simpler, the driving assembly occupies smaller space and weighs less. The layout space of the air treatment equipment can be saved, the arrangement of other components is facilitated, and the energy consumption of the air treatment equipment can be saved.

[0084] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0085] This application provides an air handling device, which includes, but is not limited to, air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air systems. In this application embodiment, an air conditioning unit is used as an example for description. The air conditioning unit may include wall-mounted air conditioners, floor-standing air conditioners, central air conditioning systems, ducted air conditioners, etc.

[0086] The following explanation will use a wall-mounted air conditioner as an example of an air handling unit.

[0087] Figure 1 This is a schematic diagram of an air handling device provided in an embodiment of this application. (Refer to...) Figure 1 As shown, the air handling unit 1 includes a unit body 10, which has an air outlet 11 through which the air handling unit 1 supplies air to the outside. Taking a wall-mounted air conditioner as an example, the air handling unit 1 is installed on an indoor wall, and the air outlet 11 can be located on the front (the side facing away from the wall) of the unit body 10 and near the lower part. For example, the air outlet 11 can be tilted downwards, making the air supply area of ​​the air handling unit 1 more suitable.

[0088] An air guide assembly 20 is provided at the air outlet 11 of the equipment body 10. The air guide assembly 20 is used to adjust the air delivery direction and air delivery area of ​​the air handling equipment 1 so as to achieve flexible air delivery of the air handling equipment 1.

[0089] Figure 2 This is a three-dimensional structural diagram of an air guide component provided in an embodiment of this application.

[0090] Reference Figure 2 As shown, the air guiding assembly 20 includes an adjustment assembly 100, which is disposed within the air duct of the device body 10. The air duct has a mounting base for the adjustment assembly 100, on which the adjustment assembly 100 can be installed. For ease of explanation, this embodiment defines a basic air duct wall 12, which may be, for example, the side wall of the air duct closest to a wall. The adjustment assembly 100 can be installed on the basic air duct wall 12. The adjustment assembly 100 can be directly installed on the basic air duct wall 12, or it can be installed on the basic air duct wall 12 through other supporting components. Furthermore, the adjustment assembly 100 can be located at the air outlet 11 of the device body 10. For example, the adjustment assembly 100 can cover most of the area of ​​the air outlet 11, so that the air delivery direction and air delivery area of ​​the device body 10 can be adjusted by the adjustment assembly 100.

[0091] The adjusting assembly 100 can include a bearing plate 110 and a plurality of air guide blades 120. The bearing plate 110 can be mounted to the base air duct wall 12, and a plate surface of the bearing plate 110 can be parallel to a wall surface of the base air duct wall 12, for example. Also, the bearing plate 110 can extend along a length direction of the air outlet 11 to enable the adjusting assembly 100 to cover the air outlet 11. The air guide blades 120 are arranged in sequence along the plate surface of the bearing plate 110, and each air guide blade 120 is movably connected to the bearing plate 110.

[0092] The bearing plate 110 is close to the base air duct wall 12 to facilitate mounting of the adjusting assembly 100 to the base air duct wall 12 through the bearing plate 110. The air guide blades 120 can be located on a side plate surface of the bearing plate 110 that faces away from the base air duct wall 12, the air guide blades 120 face the air outlet 11, and the air guide blades 120 extend toward the air outlet 11. In this way, the airflow in the air duct can be blown out from the air outlet 11 after passing through the air guide blades 120 to guide the airflow by the air guide blades 120.

[0093] Continuing to refer to Figure 2 The air guide assembly 20 further includes a driving assembly 200 connected with the adjusting assembly 100. The driving assembly 200 drives the adjusting assembly 100 to move to realize adjustment of the air supply direction and the air supply area by the adjusting assembly 100.

[0094] In this embodiment, the bearing plate 110 is also movably connected to the base air duct wall 12. The driving assembly 200 can drive each air guide blade 120 on the bearing plate 110 to move, and the driving assembly 200 can also drive the bearing plate 110 to move. When the driving assembly 200 drives the bearing plate 110 to move, each air guide blade 120 on the bearing plate 110 moves together with the bearing plate 110. Meanwhile, each air guide blade 120 can also move relative to the bearing plate 110.

[0095] The driving assembly 200 can be arranged on a side of the bearing plate 110 that faces the base air duct wall 12. That is, the air guide blades 120 and the driving assembly 200 can be located on two sides of the bearing plate 110 in a thickness direction. In this way, the driving assembly 200 can be directly connected with the bearing plate 110 to facilitate driving of the bearing plate 110 and the air guide blades 120 on the bearing plate 110 by the driving assembly 200. Also, the driving assembly 200 does not occupy the space of the bearing plate 110 on the side where the air guide blades 120 are located, which can increase the layout space of the air guide blades 120 and be beneficial to improving the air guiding effect of the air guide assembly 20. Meanwhile, the side of the bearing plate 110 that faces the base air duct wall 12 also has sufficient space to arrange the driving assembly 200, which is beneficial to the design and installation of the driving assembly 200. In addition, the bearing plate 110 can shield the driving assembly 200 to improve the appearance effect of the air handling device 1.

[0096] The air guide assembly 20 can also be controlled by a control element, which is electrically connected with the driving assembly 200. For example, the control element is connected with the driving assembly 200 through a signal line, or the control element and the driving assembly 200 are connected in wireless communication. The driving assembly 200 is controlled by the control element to control the swing direction and deflection angle of the air guide blades 120 and the swing direction and deflection angle of the bearing plate 110, so as to accurately control the air supply direction and air supply area of the adjustment assembly 100.

[0097] The driving assembly 200 drives the movement of each air guide blade 120 on the bearing plate 110, so that the position of each air guide blade 120 relative to the bearing plate 110 changes. The included angle between each air guide blade 120 and a certain direction of the surface of the bearing plate 110 changes, and each air guide blade 120 deflects towards one side of the air outlet 11 to adjust the air supply angle of the air guide assembly 20.

[0098] The driving assembly 200 drives the movement of the bearing plate 110, so that the position of the bearing plate 110 relative to the air outlet 11 changes, and the distance between the bearing plate 110 and the base air duct wall 12 changes. The movement of the bearing plate 110 together with each air guide blade 120 on the bearing plate 110 can change the position of the air guide blade 120 relative to the air outlet 11, weaken or even eliminate the deflection angle limitation of the air duct on the air guide blade 120. In this way, the deflection angle range of the air guide blade 120 relative to the bearing plate 110 can be increased. When the deflection angle of the bearing plate 110 relative to the air outlet 11 is adjustable, the deflection angle of the air guide blade 120 relative to the bearing plate 110 can be adjusted on the basis of changing the deflection angle of the bearing plate 110, which can further increase the deflection angle range of the air guide blade 120 relative to the air outlet 11.

[0099] In this way, the driving assembly 200 not only drives the movement of each air guide blade 120 on the bearing plate 110, but also drives the movement of the bearing plate 110 together with the air guide blades 120, so that the driving mode of the driving assembly 200 on the adjustment assembly 100 is more flexible. In this way, the air supply angle of the air guide assembly 20 can be flexibly adjusted, the air supply area of the air guide assembly 20 can be expanded, the air supply coverage area of the air guide assembly 20 is larger, and large-area area air supply can be realized. The indoor temperature can be adjusted more quickly, the temperature uniformity in the room can be improved, and the comfort in the room can be improved.

[0100] And, since the driving assembly 200 can drive the air guide blades 120 to move and drive the bearing plate 110 to move, the flexibility of the driving assembly 200 in adjusting the air guide assembly 20 is improved. The air guide assembly 20 can blow air towards more areas, and the accuracy of the air guide assembly 20 in adjusting the air blowing area can be improved. In this way, by adjusting the air blowing angle of the air guide assembly 20 through the driving assembly 200, the air blowing area of the air guide assembly 20 can be avoided from the active area of the user, so as to avoid the discomfort or health problems caused by the direct blowing of cold air to the user. The air blowing angle of the air guide assembly 20 can also be continuously changed through the driving assembly 200, so as to avoid the air guide assembly 20 from blowing air to a certain area for a long time, and improve the uniformity of the overall indoor temperature.

[0101] In addition, since the embodiment only needs to set one driving assembly 200 to achieve the movement of the air guide blades 120 and the movement of the bearing plate 110. In this way, the driving mode of the air guide assembly 20 is simpler, the number of driving assemblies 200 is reduced, the occupied space of the driving assembly 200 is reduced, and the overall volume of the air guide assembly 20 is smaller. The driving assembly 200 consumes less energy, which is conducive to reducing the energy consumption of the air guide assembly 20 and improving the overall energy efficiency of the air handling equipment 1.

[0102] In the embodiment, the movement mode of the driving assembly 200 in driving the bearing plate 110 to move can be swinging, and the bearing plate 110 can swing (or be considered as rotating) on the base air duct wall 12 about the rotation axis of the bearing plate 110. Further, the position of the bearing plate 110 relative to the air outlet 11 is changed, and the included angle of the bearing plate 110 relative to the plane direction of the air outlet 11 is changed. Taking one end of the bearing plate 110 away from the rotation axis of the bearing plate 110 as a reference, the end of the bearing plate 110 swings towards the air outlet 11 (for example, the end of the bearing plate 110 extends out of the air outlet 11), or the end of the bearing plate 110 swings away from the air outlet 11 (for example, the end of the bearing plate 110 is withdrawn into the air outlet 11).

[0103] In this way, the driving assembly 200 not only drives the air guide blades 120 to swing relative to the bearing plate 110, changes the included angle between the air guide blades 120 and the plane of the bearing plate 110 in a certain direction, and adjusts the air blowing direction through the swinging of the air guide blades 120. And, the driving assembly 200 also drives the bearing plate 110 to swing relative to the air outlet 11, and superimposes the deflection angle of the bearing plate 110 on the deflection angle of the air guide blades 120, to achieve the adjustment of the air blowing direction. In this way, the air blowing angle range of the adjustment assembly 100 is increased, the air blowing area of the adjustment assembly 100 is expanded, and the air blowing coverage area of the air handling equipment 1 is larger.

[0104] Of course, in other embodiments, the driving assembly 200 can also drive the bearing plate 110 to move in a translational manner, and the length direction of the bearing plate 110 is always consistent with the length direction of the air outlet 11, and the bearing plate 110 moves along the width direction of the air outlet 11 on the base air duct wall 12. Further, the position of the bearing plate 110 relative to the air outlet 11 is changed. For example, the bearing plate 110 moves from a position accommodated in the air duct to a position towards the air outlet 11, for example, the bearing plate 110 moves to the plane where the air outlet 11 is located, or even the bearing plate 110 is entirely extended out of the air outlet 11. Alternatively, the bearing plate 110 moves from a position located in the plane where the air outlet 11 is located or outside the air outlet 11 to the air duct, so as to recover the bearing plate 110 into the air duct.

[0105] In this way, the driving assembly 200 can drive the bearing plate 110 to move towards the air outlet 11, so that the air guide blades 120 on the bearing plate 110 are closer to the air outlet 11, or even extended out of the air outlet 11. It can avoid the limitation caused by the swing range of the air guide blades 120 in the air duct, and increase the deflection angle unit of the air guide blades 120. Further, the air supply area of the adjusting assembly 100 is expanded, and the air supply coverage area of the air handling equipment 1 is expanded. When the deflection angle of the air guide blades 120 is too large, and the air supply area of the air guide assembly 20 is towards the edge of the air outlet 11, the air duct can also avoid the air supply of the air guide assembly 20, and avoid the air supply flow to be disturbed.

[0106] The following are all examples of driving the bearing plate 110 to swing on the base air duct wall 12 by the driving assembly 200.

[0107] Figure 3 The schematic diagram of the air guide assembly provided by the embodiments of the present application in an initial state is shown. Figure 4 The schematic diagram of the air guide assembly provided by the embodiments of the present application in a working state is shown. Figure 5 The schematic diagram of the air guide assembly provided by the embodiments of the present application in another working state is shown.

[0108] It should be noted that, Figures 3 to 5 The installation structure of the air guide assembly 20 is only shown in the figures. The air guide assembly 20 is shown in the front view of the air guide assembly 20, and the front view of the air guide assembly 20 is in the plane direction of the installation base (the base air duct wall 12). Therefore, the plane direction can also correspond to the plane direction of the bearing plate 110, and the blade surface of the air guide blade 120 is perpendicular to the plane direction. This does not limit the installation orientation of the air guide assembly 20 in the air handling equipment 1.

[0109] Referring to Figures 3 to 5In some embodiments, the air guiding assembly 20 can be used to realize left-right air sweeping. In this case, the air guiding vanes 120 installed on the carrier plate 110 can be arranged in sequence and at intervals along the length direction of the carrier plate 110, and the air flow in the air duct is guided through the air guiding passages formed between two adjacent air guiding vanes 120. The air guiding vanes 120 can swing towards the two ends of the length direction of the air outlet 11, or in other words, the air guiding vanes 120 can swing towards the left and right ends of the air outlet 11 to guide the air flow to the left or right side of the air outlet 11.

[0110] For example, the air guiding vanes 120 can be rotatably connected to the carrier plate 110 (see FIG. 4). Figure 2 In this case, the rotation axes of the air guiding vanes 120 can be perpendicular to the plate surface of the carrier plate 110, and the air surfaces of the air guiding vanes 120 can also be perpendicular to the plate surface of the carrier plate 110. The driving assembly 200 can drive the air guiding vanes 120 to rotate along their rotation axes to realize the swinging of all the air guiding vanes 120 towards the left and right ends of the air outlet 11.

[0111] In some other embodiments, the air guiding assembly 20 can also be used to realize up-down air sweeping. In this case, the air guiding vanes 120 installed on the carrier plate 110 can be arranged in sequence and at intervals along the width direction of the carrier plate 110, and the air flow in the air duct is guided through the air guiding passages formed between two adjacent air guiding vanes 120. The air guiding vanes 120 can swing towards the two ends of the height direction (or width direction) of the air outlet 11, or in other words, the air guiding vanes 120 can swing towards the upper and lower ends of the air outlet 11 to guide the air flow to the upper or lower side of the air outlet 11.

[0112] For example, the air guiding vanes 120 can also be rotatably connected to the carrier plate 110. In this case, the rotation axes of the air guiding vanes 120 can be parallel to the plate surface of the carrier plate 110, and the air guiding vanes 120 can be connected to the carrier plate 110 through support members. For example, the two ends of the extension direction of the air guiding vanes 120 are the rotation axes, the rotation axes of the two ends of the air guiding vanes 120 are rotatably connected to the carrier plate 110 through the support members, and there is a gap between the air guiding vanes 120 and the plate surface of the carrier plate 110. The driving assembly 200 can drive the air guiding vanes 120 to rotate along their rotation axes to realize the swinging of all the air guiding vanes 120 towards the upper and lower ends of the air outlet 11.

[0113] In other embodiments, the air guiding assembly 20 can also be used to realize air sweeping in different directions. For example, the air guiding assembly 20 can realize both left-right air sweeping and up-down air sweeping. That is, each air guiding blade 120 can swing towards both ends (left and right ends) of the length direction of the air outlet 11, and each air guiding blade 120 can also swing towards both ends (upper and lower ends) of the height direction of the air outlet 11.

[0114] For example, each air guiding blade 120 can also be rotatably connected to the carrier plate 110. Since the air guiding assembly 20 can realize air sweeping in different directions, each air guiding blade 120 can have a rotation axis in different directions. For example, each air guiding blade 120 has a rotation axis perpendicular to the plate surface of the carrier plate 110, and each air guiding blade 120 has a rotation axis parallel to the plate surface of the carrier plate 110. All air guiding blades 120 are installed on the carrier plate 110 in the form of air guiding groups, each air guiding group includes a plurality of air guiding blades 120, each air guiding group is rotatably connected to the carrier plate 110 by a rotation axis perpendicular to the plate surface of the carrier plate 110, and each air guiding blade 120 in each air guiding group is provided with a rotation axis parallel to the plate surface of the carrier plate 110.

[0115] The following will be described by taking the air guiding assembly 20 shown in Figures 3 to 5 The air guiding blades 120 are sequentially arranged along the length direction of the carrier plate 110, each air guiding blade 120 is rotatably connected to the carrier plate 110, and the rotation axis of each air guiding blade 120 is perpendicular to the plate surface of the carrier plate 110.

[0116] As for the number design of the adjusting assemblies 100 in the air guiding assembly 20, the following will be described by continuing to refer to Figures 3 to 5 As an embodiment, the number of the adjusting assemblies 100 can be two, and the two adjusting assemblies 100 can be arranged in the length direction of the air outlet 11. Matching the number of the adjusting assemblies 100, the number of the driving assemblies 200 can also be two. The two driving assemblies 200 are respectively connected to the two adjusting assemblies 100, and each driving assembly 200 drives the corresponding adjusting assembly 100 to move.

[0117] By arranging the two adjusting assemblies 100 in the length direction of the air outlet 11 and arranging the two driving assemblies 200 to independently drive the two adjusting assemblies 100, the two adjusting assemblies 100 can respectively send air to different areas, and the two adjusting assemblies 100 respectively have different air sending areas, which can expand the air sending area of the air guiding assembly 20 and expand the air handling equipment 1 air coverage area.

[0118] As an embodiment, the number of the adjusting assemblies 100 can be two, and the two adjusting assemblies 100 can be arranged in the length direction of the air outlet 11. Matching the number of the adjusting assemblies 100, the number of the driving assemblies 200 can also be two. The two driving assemblies 200 are respectively connected to the two adjusting assemblies 100, and each driving assembly 200 drives the corresponding adjusting assembly 100 to move. Figures 3 to 5For example, in the paper plane direction, the adjusting assembly 100 on the left is driven by the corresponding driving assembly 200 to deflect the air guide blade 120 of the adjusting assembly 100 to the left, and the adjusting assembly 100 on the right is driven by the corresponding driving assembly 200 to deflect the air guide blade 120 of the adjusting assembly 100 to the right, so that the air supply area of the air guide assembly 20 as a whole is expanded. On this basis, if the two driving assemblies 200 drive the bearing plates 110 in the adjusting assemblies 100 on the left to deflect to the left and the bearing plates 110 in the adjusting assemblies 100 on the right to deflect to the right, respectively, the air supply area of the air guide assembly 20 as a whole is further expanded.

[0119] For example, taking the air handling device 1 as a wall-mounted air conditioner, the air conditioner has a larger air supply coverage area, can more uniformly adjust the temperature of the entire indoor space, reduces the temperature difference in the indoor space, and improves the overall comfort of the indoor space. Moreover, the larger air supply coverage area also enables the air conditioner to reach the set temperature target faster, and the air conditioner can complete the cooling target or heating target in a shorter time, and the energy efficiency of the air conditioner is higher. In addition, the larger air supply coverage area enables the air flow distribution area of the air flow blown by the air conditioner to be wider and the air flow velocity to be more gentle, which can reduce the discomfort caused by strong wind in a local area, provide a softer air supply effect, and enable the user to have a more natural and comfortable feeling in the air conditioner environment.

[0120] Moreover, by independently driving the two adjusting assemblies 100 through the two driving assemblies 200, the air supply areas of the two adjusting assemblies 100 can be independently adjusted, and there is no linkage relationship between the two adjusting assemblies 100. In this way, the air handling device 1 can be suitable for different indoor layouts and use requirements, and the user can flexibly adjust and control the air supply areas of the two adjusting assemblies 100 according to actual conditions. In order to meet the needs of different environments for different air supply areas, so that the air flow blown by the air handling device 1 is fully and effectively utilized, and waste is avoided.

[0121] The two driving assemblies 200 can be symmetrically arranged, specifically symmetrically arranged with the center line between the two adjusting assemblies 100 as the axis of symmetry. In this way, for the air guide assembly 20 as a whole, the structure is more symmetrical, the overall stress is more balanced, the stability is better, and the reliability is higher. Moreover, in the case that the driving capabilities of the driving assemblies 200 are consistent, the coverage ranges of the air supply areas of the two adjusting assemblies 100 remain symmetrical, the air supply coverage areas of the two adjusting assemblies 100 are the same and have no obvious difference, the air guide assembly 20 has better universality, and the application scenarios of the air handling device 1 are more diverse. In addition, the air guide assembly 20 is easier to assemble, without the need to distinguish the installation positions of the two adjusting assemblies 100, and the assembly efficiency is higher.

[0122] On this basis, the driving assembly 200 can be arranged closer to one end of the corresponding adjustment assembly 100 away from the other adjustment assembly 100. That is, the position of the driving assembly 200 is closer to the end of the length direction of the air outlet 11. For the two adjustment assemblies 100, the two driving assemblies 200 are respectively closer to the two ends of the length direction of the air outlet 11.

[0123] The rotation center of the adjustment assembly 100 is located at the position of the driving assembly 200. By arranging the driving assembly 200 closer to one end of the adjustment assembly 100, the rotation arm between the rotation center of the adjustment assembly 100 and the other end of the adjustment assembly 100 is longer. When the driving assembly 200 is away from the opposite ends of the two adjustment assemblies 100, the rotation arm between the rotation center of the adjustment assembly 100 and the end of the adjustment assembly 100 close to the central region of the air outlet 11 is longer. Under the same driving effect, compared with the case that the driving assembly 200 is close to the opposite ends of the two adjustment assemblies 100, when the driving assembly 200 is close to the ends of the two adjustment assemblies 100 away from each other, the opposite ends of the two adjustment assemblies 100 can extend further out of the air outlet 11.

[0124] When the opposite ends of the two adjustment assemblies 100 extend out of the air outlet 11, the bearing plates 110 of the two adjustment assemblies 100 are respectively deflected towards the sides where they are located, and the two adjustment assemblies 100 assume an outwardly expanded posture, and the air supply area of the air guide assembly 20 as a whole is larger. The farther the opposite ends of the two adjustment assemblies 100 extend out of the air outlet 11, the more the adjustment assemblies 100 are exposed outside the air outlet 11 when the two adjustment assemblies 100 assume the outwardly expanded posture. In this way, the air supply area of the two adjustment assemblies 100 is larger, and the air supply coverage area of the air guide assembly 20 as a whole is wider. At the same time, when the two adjustment assemblies 100 assume the outwardly expanded posture, the adjustment assemblies 100 have less parts located in the air duct, and the air duct has less shielding of the adjustment assemblies 100, so that the air supply blind area can be avoided. Moreover, since the adjustment assemblies 100 have less parts located in the air duct, the movement space required by the adjustment assemblies 100 in the air duct is also smaller, so that the adjustment assemblies 100 can avoid interference with the air duct wall, which is conducive to reducing the overall volume of the air handling device 1.

[0125] For example, two driving assemblies 200 can be respectively located at the ends of the two adjusting assemblies 100 away from each other. In this way, the position of the driving assembly 200 reaches the limit of the optimal design, and when the two adjusting assemblies 100 reach the limit of the outward expansion (the deflection angle of the bearing plate 110 reaches the limit), the adjusting assembly 100 is almost entirely exposed. This avoids the interference and limitation of the air duct on the guide vane 120, avoids the occurrence of the air supply blind area, and can maximize the limit deflection angle of the guide vane 120 (the deflection angle of the guide vane 120 reaches the maximum), so as to further expand the air supply area of the adjusting assembly 100 and expand the air supply coverage area of the entire guide assembly 20.

[0126] As another embodiment, the guide assembly 20 can also include only one adjusting assembly 100, and a driving assembly 200 corresponding thereto can be arranged to drive the adjusting assembly 100. Under the driving of the driving assembly 200, the guide vane 120 of the adjusting assembly 100 can be deflected relative to the bearing plate 110, and the bearing plate 110 can also be deflected relative to the air outlet 11. Thus, the air supply area of the adjusting assembly 100 is large enough to meet the general indoor space requirements.

[0127] For example, when the air treatment device 1 is applied in a residential living space, the indoor space is small, and only one adjusting assembly 100 can meet the indoor space requirements. Alternatively, when the deflection angle range of the guide vane 120 of the adjusting assembly 100 is large, the deflection angle range of the bearing plate 110 is also large, and the guide vane 120 and the bearing plate 110 are superimposed to make the adjusting assembly 100 have a large air supply area, one adjusting assembly 100 can also meet the air supply requirements of a larger space, and then the guide assembly 20 can include only one adjusting assembly 100.

[0128] When the guide assembly 20 includes only one adjusting assembly 100, the driving assembly 200 can be connected to the middle region of the adjusting assembly 100 in the length direction. In this way, the overall force of the guide assembly 20 is more balanced, and the reliability is higher. Moreover, the deflection amplitudes of the adjusting assembly 100 to both sides are consistent, the air supply balance of the guide assembly 20 is better, and the universality is higher.

[0129] Alternatively, the driving assembly 200 can be connected to one end of the adjusting assembly 100 in the length direction, and the adjusting assembly 100 rotates around the one end. The part of the adjusting assembly 100 that can extend out of the air outlet 11 is more, and the adjusting assembly 100 can be almost entirely exposed. In this way, the interference and limitation of the air duct on the guide vane 120 can be avoided, the air supply blind area can be avoided, and the limit deflection angle of the guide vane 120 can be maximized designed to maximize the air supply area of the adjusting assembly 100.

[0130] Of course, in other embodiments, the air guide assembly 20 can also include more than three adjusting assemblies 100, and the number of driving assemblies 200 can also be more than three, and the driving assemblies 200 can be arranged one-to-one with the air guide assembly 20. For example, when the air handling device has a large volume and a large length of the air outlet 11, a plurality of adjusting assemblies 100 can be arranged in sequence along the length direction of the air outlet 11, and each adjusting assembly 100 can maintain a suitable length to meet the requirements of stability and reliability of the adjusting assembly 100. Alternatively, when the air handling device 1 is applied in a large space such as an office or a factory, the air guide assembly 20 can have a larger air supply coverage area by arranging a plurality of adjusting assemblies 100 to meet the air supply requirements of the large space.

[0131] In this embodiment, the driving assembly 200 is designed to drive the air guide blade 120 to rotate continuously, and when the bearing plate 110 needs to swing, the driving assembly 200 also drives the bearing plate 110 to swing. Therefore, the movement mode of the driving assembly 200 driving the adjusting assembly 100 includes two modes, which are the first movement mode and the second movement mode.

[0132] The first movement mode is that the air guide blade 120 swings and the bearing plate 110 moves. That is, when the driving assembly 200 operates, the air guide blade 120 swings on the bearing plate 110, and at the same time, the bearing plate 110 also moves. The second movement mode is that the air guide blade 120 swings and the bearing plate 110 does not move. That is, when the driving assembly 200 operates, only the air guide blade 120 moves on the bearing plate 110, and the bearing plate 110 remains in a stationary state.

[0133] It should be noted that the driving assembly 200 can drive the bearing plate 110 to move between the initial position and the limit position. When the bearing plate 110 is in the initial position, the bearing plate 110 is completely accommodated in the air outlet 11 (or in the air duct), and the length direction of the bearing plate 110 can be parallel to the length direction of the air outlet 11. When the bearing plate 110 is in the limit position, the bearing plate 110 can at least partially extend out of the air outlet 11. Taking the example of the driving assembly 200 driving the bearing plate 110 to swing, the limit position of the bearing plate 110 is the limit deflection position. When the bearing plate 110 is in the limit deflection position, one side of the bearing plate 110 located at a certain position (which is the rotation center of the bearing plate 110) of the driving assembly 200 can extend out of the air outlet 11.

[0134] The carrier plate 110 can be kept at the initial position, or the carrier plate 110 can be kept at the limit position. Thus, when the adjustment assembly 100 is in the first movement mode, the carrier plate 110 can move between the initial position and the limit position, while the guide vane 120 rotates on the carrier plate 110 about the rotation axis of the guide vane 120. When the adjustment assembly 100 is in the second movement mode, the carrier plate 110 can stay at the initial position or the limit position, and only the guide vane 120 rotates on the carrier plate 110 about the rotation axis of the guide vane 120.

[0135] Specifically, when the control member does not receive the demand signal of the air supply angle γ, the adjustment assembly 100 can be in the initial state. When the control member receives the demand signal of the air supply angle γ sent by the user, the control member controls the driving assembly 200 to operate. And according to the specific size of the air supply angle γ, the driving assembly 200 drives the adjustment assembly 100 to move in the first movement mode or in the second movement mode.

[0136] Referring to Figure 3 As shown in the figure, the guide vane assembly 20 is shown in the initial state. When the adjustment assembly 100 is in the initial state, the carrier plate 110 and the guide vane 120 are both in the initial position. When the carrier plate 110 is in the initial position, the carrier plate 110 is completely accommodated in the air outlet 11, and the length direction of the carrier plate 110 is parallel to the length direction of the air outlet 11. When the guide vane 120 is in the initial position, the guide vane 120 is parallel to the length direction of the carrier plate 110 (at this time, the blade surfaces of all the guide vanes 120 are in the same plane). That is, when the adjustment assembly 100 is in the initial state, the guide vane 120 is parallel to the length direction of the air outlet 11, and the included angle between the guide vane 120 and the length direction of the air outlet 11 is 0°.

[0137] In order to facilitate the description of the working principle of the guide vane assembly 20, the embodiment defines the limit deflection angle α of the guide vane 120. The limit deflection angle of the guide vane 120 is the maximum deflection angle of the guide vane 120 relative to its initial position. The limit deflection angle α of the guide vane 120 is the included angle between the guide vane 120 and the length direction of the carrier plate 110 when the guide vane 120 is in the limit deflection position.

[0138] And the embodiment defines the limit deflection angle β of the carrier plate 110. The limit deflection angle of the carrier plate 110 is the maximum deflection angle of the carrier plate 110 relative to its initial position. The limit deflection angle β of the carrier plate 110 is the included angle between the carrier plate 110 and the length direction of the air outlet 11 when the carrier plate 110 is in the limit deflection position.

[0139] Referring to Figure 4As shown in the figure, the air guide assembly 20 is in the first working state. When the air supply angle θ is greater than the limit deflection angle α of the air guide blade 120, the driving assembly 200 drives the air guide blade 120 to rotate relative to the bearing plate 110, and at the same time, the driving assembly 200 also drives the bearing plate 110 to swing relative to the air outlet 11.

[0140] At this time, the driving assembly 200 first drives the adjusting assembly 100 to move in the first movement mode. The driving assembly 200 drives the bearing plate 110 to rotate with a certain center of the driving assembly 200 as the center, and the bearing plate 110 swings to the limit deflection position, and the rotation angle of the bearing plate 110 relative to the initial position is the limit deflection angle β. During this period, the driving assembly 200 also drives the air guide blade 120 to rotate on the bearing plate 110 by an angle γ around the rotation axis of the air guide blade 120. In this way, the rotation angle of the air guide blade 120 relative to the initial position is β+γ.

[0141] If the requirement of the air supply angle θ is still not met, the driving assembly 200 continues to drive the adjusting assembly 100 to move in the second movement mode. The driving assembly 200 limits the bearing plate 110 at the limit deflection position, and the bearing plate 110 no longer rotates. At the same time, the driving assembly 200 drives the air guide blade 120 to rotate on the bearing plate 110 by an angle δ around the rotation axis of the air guide blade 120. In this way, the rotation angle of the air guide blade 120 relative to the initial position is β+γ+δ, and θ=β+γ+δ.

[0142] Referring to Figure 5 As shown in the figure, the air guide assembly 20 is in the second working state. When the air supply angle θ is less than the limit deflection angle α of the air guide blade 120, the driving assembly 200 only needs to drive the air guide blade 120 to rotate relative to the bearing plate 110, and the bearing plate 110 can remain in the initial position and be stationary.

[0143] At this time, the driving assembly 200 drives the adjusting assembly 100 to move in the second movement mode. The driving assembly 200 limits the bearing plate 110 at the initial position, and the bearing plate 110 does not rotate. And the driving assembly 200 only drives the air guide blade 120 to rotate on the bearing plate 110 by an angle δ around the rotation axis of the air guide blade 120. In this way, the rotation angle of the air guide blade 120 relative to the initial position is δ, and θ=δ.

[0144] Figure 6 The driving mode of the air guide assembly provided in the embodiments of the present application is shown in the figure. Referring to Figure 6As shown, in this embodiment, the driving assembly 200 used to drive the adjustment assembly 100 to move includes a driving motor 210 and a transmission member 220, which is drivingly connected between the driving motor 210 and the adjustment assembly 100. The driving motor 210 is used to provide driving force, and the driving motor 210 can be electrically connected with the control member to control the driving motor 210 to operate through the control member. The transmission member 220 is used to transmit the driving force of the driving motor 210 to the adjustment assembly 100 to drive the adjustment assembly 100 to move.

[0145] The transmission member 220 can be drivingly connected with the bearing plate 110. The driving assembly 200 transmits the driving force to the transmission member 220 to drive the bearing plate 110 to move through the transmission member 220. Each of the guide vanes 120 on the bearing plate 110 can be directly connected with the output end of the driving motor 210 to be directly driven to rotate by the driving motor 210. Alternatively, each of the guide vanes 120 can be connected with the transmission member 220 to be driven to rotate by the transmission member 220.

[0146] In this way, only one driving motor 210 cooperates with the transmission member 220 to drive each of the guide vanes 120 on the bearing plate 110 to rotate and drive the bearing plate 110 to move. The structure of the driving assembly 200 is simpler, and the driving mode of the adjustment assembly 100 is simplified. Moreover, there is no other driving component in the driving assembly 200, the driving assembly 200 occupies less space and weighs less as a whole, which can save the space of the air guiding assembly 20, facilitate the layout design of other components in the air handling equipment 1, and is conducive to the lightweight of the air handling equipment 1. In addition, only one driving motor 210 is used to drive the adjustment assembly 100 to move, which maximizes the use of the number of driving motors 210 and can reduce the energy consumption of the air guiding assembly 20.

[0147] In the driving assembly 200, the transmission member 220 can include a first transmission part 221 and a second transmission part 222 (see Figure 7 The first transmission part 221 is connected with the driving motor 210, and the second transmission part 222 is drivingly connected between the first transmission part 221 and the bearing plate 110. The driving motor 210 can directly drive each of the guide vanes 120 to rotate, or the driving motor 210 drives each of the guide vanes 120 to rotate through the first transmission part 221. Moreover, the driving motor 210 can transmit the driving force to the first transmission part 221, and the first transmission part 221 and the second transmission part 222 are drivingly connected with each other to finally drive the bearing plate 110 to move through the second transmission part 222.

[0148] The first transmission part 221 is directly connected with the driving motor 210, and the first transmission part 221 can also continuously operate in the process that the driving motor 210 continuously operates. In this way, the continuous rotation of the guide vanes 120 can be realized whether the driving motor 210 directly drives the rotation of the guide vanes 120 or the driving motor 210 drives the rotation of the guide vanes 120 through the first transmission part 221.

[0149] By designing the structure of the first transmission part 221 and the second transmission part 222, it is realized that the first transmission part 221 can transmit power to the second transmission part 222, and the first transmission part 221 can also not transmit power to the second transmission part 222. When the first transmission part 221 transmits power to the second transmission part 222, the second transmission part 222 operates, and the second transmission part 222 drives the movement of the bearing plate 110. At this time, the guide vanes 120 rotate relative to the bearing plate 110, and the bearing plate 110 also moves relative to the air outlet 11. When the first transmission part 221 does not transmit power to the second transmission part 222, the second transmission part 222 stops operating, and the second transmission part 222 limits the bearing plate 110 at the current position (for example, the initial position or the limit position). At this time, only the guide vanes 120 rotate relative to the bearing plate 110, and the bearing plate 110 does not move.

[0150] For example, the second transmission part 222 can be located on the side of the first transmission part 221 close to the bearing plate 110. In this way, the first transmission part 221 and the second transmission part 222 are adjacent, which facilitates the transmission of power between them. The second transmission part 222 is also closer to the bearing plate 110, which facilitates the connection between the second transmission part 222 and the bearing plate 110. Moreover, the first transmission part 221 and the second transmission part 222 are stacked, the volume of the transmission member 220 is smaller, the driving assembly 200 occupies less space as a whole, and the degree of integration is higher.

[0151] It should be noted that the second transmission part 222 of the present embodiment is located on the side of the first transmission part 221 close to the bearing plate 110, which does not mean that the second transmission part 222 is entirely located on the side of the first transmission part 221. The second transmission part 222 and the first transmission part 221 can also have parts located in the same space to facilitate the transmission between the second transmission part 222 and the first transmission part 221.

[0152] Figure 7 A sectional view of the transmission member provided by the present embodiment. Figure 8 A planar perspective view of the transmission member in Figure 7

[0153] Referring to Figure 7 and Figure 8 ​As shown, in this embodiment, the transmission member 220 connected between the driving assembly 200 and the bearing plate 110 can be a gear set 220a. With the gear set 220a as the transmission member 220, the transmission between the driving motor 210 and the bearing plate 110 is realized through gear transmission.

[0154] The gear set 220a mainly realizes transmission through the setting of mutually meshing and coaxial gears, and is mainly used to drive the target structural member to rotate. In this way, the gear set 220a can drive the bearing plate 110 to swing to change the included angle of the bearing plate 110 relative to the length direction of the air outlet 11. Moreover, the gear set 220a is tightly matched, the gears in the gear set 220a are meshed, stacked and butted, and the overall volume of the gear set 220a is small, which is conducive to reducing the overall occupied space of the driving assembly 200. In addition, the gear set 220a can realize precise transmission, not only with high transmission efficiency, but also with high transmission precision, which can improve the driving precision of the driving assembly 200 and the precision of the air guide assembly 20 in adjusting the blowing angle.

[0155] Of course, in other embodiments, the transmission member 220 can also be in other architectural forms, and the transmission member 220 can transmit power through other transmission modes. For example, the transmission member 220 can be a connecting rod 130a transmission, a telescopic rod transmission, a gear and rack transmission or other transmission architectures. The transmission member 220 can drive the bearing plate 110 to swing, or the transmission member 220 can also drive the bearing plate 110 to translate. This embodiment does not make any limitation.

[0156] Continuing to refer to Figure 7 and Figure 8 , the gear set 220a can specifically include a first gear pair 221a and a second gear pair 222a, and the first gear pair 221a and the second gear pair 222a correspond to the aforementioned first transmission part 221 and the second transmission part 222, respectively. The first gear pair 221a is in transmission connection with the driving motor 210, for example, the first gear pair 221a can be connected with the output shaft of the driving motor 210. The second gear pair 222a is in transmission connection between the first gear pair 221a and the bearing plate 110.

[0157] The second gear pair 222a can be located on the side of the first gear pair 221a close to the bearing plate 110, facilitating the transmission connection between the first gear pair 221a and the second gear pair 222a, and facilitating the connection between the second gear pair 222a and the bearing plate 110. In the thickness direction of the bearing plate 110, the second gear pair 222a and the first gear pair 221a can have a part located in the same thickness space, so as to facilitate the transmission matching between the second gear pair 222a and the first gear pair 221a. Details are not described herein.

[0158] The gear set 220a can avoid the output shaft of the driving motor 210, the output shaft of the driving motor 210 is directly connected to each guide vane 120, and the driving motor 210 drives each guide vane 120 to continuously rotate. Alternatively, the first gear pair 221a is connected to the output shaft of the driving motor 210, and the first gear pair 221a is connected to each guide vane 120, and the first gear pair 221a drives each guide vane 120 to continuously rotate. The second gear pair 222a is in transmission connection with the bearing plate 110, and when the first gear pair 221a transmits to the second gear pair 222a, the second gear pair 222a drives the bearing plate 110 to swing; when the first gear pair 221a does not transmit to the second gear pair 222a, the bearing plate 110 remains stationary.

[0159] In combination with Figure 7 and Figure 8 , the first gear pair 221a can include a driving wheel 2211 connected to the output shaft of the driving motor 210. The second gear pair 222a can include a first transmission wheel 2221 arranged on the side of the driving wheel 2211 close to the bearing plate 110. The first transmission wheel 2221 and the driving wheel 2211 are in transmission cooperation, and the first transmission wheel 2221 is in transmission connection with the bearing plate 110.

[0160] After the driving motor 210 is started, the driving motor 210 can drive the driving wheel 2211 to continuously rotate. Through the transmission design of the driving wheel 2211 and the first transmission wheel 2221, during the rotation of the driving wheel 2211, the driving wheel 2211 can drive the first transmission wheel 2221 to rotate, and the driving wheel 2211 can not drive the first transmission wheel 2221 to rotate, and the first transmission wheel 2221 remains stationary. For example, when the driving wheel 2211 rotates to a certain angle range, the driving wheel 2211 drives the first transmission wheel 2221 to rotate; when the driving wheel 2211 rotates to other angle ranges, the first transmission wheel 2221 remains stationary.

[0161] That is, through the transmission cooperation of the driving wheel 2211 and the first transmission wheel 2221, the adjustment assembly 100 can move in the first movement mode or the second movement mode. When the driving wheel 2211 drives the first transmission wheel 2221 to rotate synchronously, the guide vanes 120 swing and the bearing plate 110 moves, and the adjustment assembly 100 moves in the first movement mode. When the driving wheel 2211 rotates and the first transmission wheel 2221 does not move, the guide vanes 120 swing and the bearing plate 110 does not move, and the adjustment assembly 100 moves in the second movement mode.

[0162] Continuing to refer to Figure 7 and Figure 8As an implementation, the first transmission wheel 2221 can be partially overlapped with the driving wheel 2211, and the driving wheel 2211 can be provided with a transmission rod 22111 on the side facing the first transmission wheel 2221. The first transmission wheel 2221 can be provided with a transmission groove 22211, which can be communicated to the side wall of the first transmission wheel 2221. When the first transmission wheel 2221 is installed, the transmission groove 22211 on the first transmission wheel 2221 is arranged towards the driving wheel 2211, so that the notch of the transmission groove 22211 is located within the coverage range of the driving wheel 2211, and the notch of the transmission groove 22211 is located on the trajectory circumference of the rotation of the transmission rod 22111 on the driving wheel 2211.

[0163] When the driving motor 210 drives the driving wheel 2211 to rotate, the transmission rod 22111 on the driving wheel 2211 performs a circular motion. When the transmission rod 22111 on the driving wheel 2211 rotates to the notch position of the transmission groove 22211 on the first transmission wheel 2221, as the driving wheel 2211 continues to rotate, the transmission rod 22111 will enter the transmission groove 22211. And the transmission rod 22111 will slide along the transmission groove 22211. During this period, the first transmission wheel 2221 is subjected to external force applied by the transmission rod 22111, and the first transmission wheel 2221 will rotate synchronously with the driving wheel 2211. Thus, the driving motor 210 or the driving wheel 2211 drives the guide vane 120 to swing, and at the same time, the first transmission wheel 2221 drives the carrier plate 110 to swing, so that the adjustment assembly 100 moves in the first movement mode.

[0164] As the driving wheel 2211 continues to rotate, the transmission rod 22111 will be separated from the transmission groove 22211. After the transmission rod 22111 is separated from the transmission groove 22211, the first transmission wheel 2221 is no longer subjected to external force, and the first transmission wheel 2221 will stop rotating and stay at the current position (at this time, the carrier plate 110 can stay at the limit position). After that, the driving wheel 2211 continues to rotate in the original direction, the transmission rod 22111 moves away from the first transmission wheel 2221, and the notch of the transmission groove 22211 can no longer correspond to the transmission rod 22111, so the driving wheel 2211 will not drive the first transmission wheel 2221 to rotate. During this period, the adjustment assembly 100 moves in the second movement mode.

[0165] If the driving motor 210 is reversed to reverse the rotation of the driving wheel 2211, the transmission rod 22111 on the driving wheel 2211 moves towards the first transmission wheel 2221, and the transmission rod 22111 can be rotated to correspond to the notch of the transmission groove 22211. When the transmission rod 22111 enters the transmission groove 22211, the transmission rod 22111 can drive the first transmission wheel 2221 to rotate during sliding along the transmission groove 22211. At this time, the first transmission wheel 2221 also reverses the rotation, and the first transmission wheel 2221 drives the bearing plate 110 to reverse swing, so that the bearing plate 110 returns to the initial position.

[0166] The transmission groove 22211 can extend along the radial direction of the first transmission wheel 2221. During the rotation of the first transmission wheel 2221 driven by the driving wheel 2211, the movement track of the transmission groove 22211 always matches the circumferential track of the transmission rod 22111. That is, the center line of the width direction of the transmission groove 22211 always keeps tangential to the circumferential track of the transmission rod 22111. In this way, the smooth sliding of the transmission rod 22111 along the transmission groove 22211 can be ensured, and the interference or jamming between the two can be avoided, so that the driving wheel 2211 can smoothly drive the first transmission wheel 2221 to rotate.

[0167] Continuing to refer to Figure 7 and Figure 8 , the first gear pair 221a can further include a first driven wheel 2212 coaxially arranged on the side of the driving wheel 2211 close to the bearing plate 110. In other words, the first driven wheel 2212 and the first transmission wheel 2221 can be arranged side by side in the same space. In this way, on the basis of the partial overlap between the first transmission wheel 2221 and the driving wheel 2211, the first driven wheel 2212 makes the gear set 220a have more overlapping parts, and the first driven wheel 2212 increases the counterweight of the gear set 220a, so that the stability and reliability of the gear set 220a are higher.

[0168] The first driven wheel 2212 and the first transmission wheel 2221 should not interfere with each other, and there is no overlapping or overlapping part between the two. In this way, the rotation of the first transmission wheel 2221 by the first driven wheel 2212 will not have an impact, so as to ensure that the driving wheel 2211 can smoothly drive the first transmission wheel 2221 to rotate.

[0169] As an implementation, the outer circumferential wall of the first transmission wheel 2221 can have at least one concave arc surface 22212 which matches the outer cylindrical surface of the first driven wheel 2212. In other words, the center of the circle of the concave arc surface 22212 of the first transmission wheel 2221 should coincide with the center of the circle of the outer cylindrical surface of the first driven wheel 2212. When assembling the gear set 220a, the transmission groove 22211 on the first transmission wheel 2221 faces the first driven wheel 2212, and the part of the outer circumferential wall of the first transmission wheel 2221 facing the first driven wheel 2212 should also be the concave arc surface 22212. While ensuring that the transmission rod 22111 can enter the transmission groove 22211, the concave arc surface 22212 of the first transmission wheel 2221 can match the outer cylindrical surface of the first driven wheel 2212.

[0170] During the rotation of the first transmission wheel 2221 driven by the driving wheel 2211, the outer cylindrical surface of the first driven wheel 2212 slides along the concave arc surface 22212 of the first transmission wheel 2221. In this way, the first driven wheel 2212 and the first transmission wheel 2221 do not interfere with each other, and the rotation of the first transmission wheel 2221 is not affected. Moreover, the first driven wheel 2212 and the second transmission wheel 2223 have matching friction surfaces between them, and a certain friction force is generated between them, which can make the movement of the first transmission wheel 2221 more stable and reliable.

[0171] For example, the outer circumferential wall of the first transmission wheel 2221 can have two or more concave arc surfaces 22212, and each concave arc surface 22212 is uniformly spaced along the circumference of the first transmission wheel 2221. In this way, the profile of the first transmission wheel 2221 is more regular and symmetrical. It is convenient for the processing and manufacturing of the first transmission wheel 2221, and the transmission groove 22211 can be arranged corresponding to any concave arc surface 22212, which can reduce the processing difficulty of the first transmission wheel 2221 and improve the processing efficiency of the first transmission wheel 2221. Moreover, the structure of the first transmission wheel 2221 is more regular and stable, the volume of the first transmission wheel 2221 extending outside the driving wheel 2211 is smaller, and the overall operation reliability of the gear set 220a is higher.

[0172] Of course, under the premise of ensuring the operation reliability of the gear set 220a, only one concave arc surface 22212 can be provided on the outer circumferential wall of the first transmission wheel 2221, and the remaining parts of the outer circumferential wall of the first transmission wheel 2221 are all cylindrical surfaces. This embodiment does not make specific limitations in this regard.

[0173] Since the driving rod 22111 is arranged on the side surface of the driving wheel 2211 facing the first driven wheel 2212, in order to ensure that the driving rod 22111 can reliably cooperate with the transmission groove 22211 of the first transmission wheel 2221, the outer peripheral wall of the first driven wheel 2212 can also be provided with an avoiding recess 22121. The avoiding recess 22121 is used to avoid the driving rod 22111 on the driving wheel 2211, and the driving rod 22111 is located on the side of the avoiding recess 22121 to leave a certain space outside the driving rod 22111, so as to avoid interference with the cooperation of the driving rod 22111 and the avoiding groove.

[0174] For example, the avoiding recess 22121 can be an arc-shaped concave surface, the axis of the driving rod 22111 can be located on the radial line of the arc-shaped concave surface, and the distance from the axis of the driving rod 22111 to both ends of the arc-shaped concave surface is equal. In this way, the driving rod 22111 can be used as a positioning reference to position the first driven wheel 2212 when the first driven wheel 2212 is assembled with the driving wheel 2211. Moreover, the first driven wheel 2212 and the driving wheel 2211 are symmetrical after assembly, and the appearance effect is better.

[0175] Continuing to refer to Figure 9 and Figure 10 , the second gear pair 222a can also include a second driven wheel 2222 coaxially arranged on the side of the first transmission wheel 2221 close to the bearing plate 110, and the bearing plate 110 is in transmission connection with the second driven wheel 2222. In this way, the second driven wheel 2222 is closer to the bearing plate 110, which facilitates the connection of the second gear pair 222a and the bearing plate 110.

[0176] Moreover, since the second driven wheel 2222 is coaxially arranged with the first transmission wheel 2221, the second driven wheel 2222 rotates synchronously with the first transmission wheel 2221. When the second driven wheel 2222 rotates synchronously with the first transmission wheel 2221, the bearing plate 110 is driven to swing. When the second driven wheel 2222 is stationary with the first transmission wheel 2221, the bearing plate 110 is limited in the initial position or the limit position, and the bearing plate 110 remains stationary.

[0177] On this basis, the second gear pair 222a can also include a second transmission wheel 2223 arranged on the side of the first driven wheel 2212 close to the bearing plate 110. Moreover, the second transmission wheel 2223 is in meshing connection with the second driven wheel 2222, and the bearing plate 110 is connected with the second transmission wheel 2223 to drive the bearing plate 110 to rotate through the second transmission wheel 2223.

[0178] The transmission ratio between the second drive wheel 2223 and the second driven wheel 2222 can be different. In other words, the outer diameters of the second drive wheel 2223 and the second driven wheel 2222 can be different. Thus, by setting the second drive wheel 2223 to mesh with the second driven wheel 2222, the second driven wheel 2222 maintains the same rotational speed as the first drive wheel 2221, but the rotational speeds of the second drive wheel 2223 and the second driven wheel 2222 are different. This allows the size of the second driven wheel 2222 to be selected according to the required swing speed of the support plate 110, maintaining an appropriate transmission ratio between the second driven wheel 2222 and the second drive wheel 2223, controlling the rotational speed of the second drive wheel 2223 within a suitable range, and ensuring the smooth swing of the support plate 110.

[0179] Since the drive motor 210 typically outputs a high speed, when transmitting power to structural components, it is often necessary to reduce the speed of the drive motor 210 and increase its torque to meet the rotational requirements of the structural components. To address this, the outer diameter of the second transmission wheel 2223 can be larger than the outer diameter of the second driven wheel 2222. The second transmission wheel 2223 can thus reduce speed and increase torque, allowing the support plate 110 to maintain a suitable swing speed. Furthermore, the greater torque between the second transmission wheel 2223 and the support plate 110 makes the movement of the support plate 110 more stable and reliable.

[0180] In addition to adjusting the output speed of the second gear pair 222a, the second transmission wheel 2223, positioned above the first driven wheel 2212, also helps to adjust the overall center of gravity of the gear set 220a, making it more stable and reliable. The second transmission wheel 2223 and the first transmission wheel 2221 can partially overlap, with the driving wheel 2211 and the second transmission wheel 2223 supporting both sides of the first transmission wheel 2221, further strengthening the overall structure of the gear set 220a.

[0181] Figure 9 This is a schematic diagram of the operation of a gear set provided in an embodiment of this application. Figure 10 This is a schematic diagram illustrating the operation of a gear set and an air guide assembly in accordance with an embodiment of this application.

[0182] Combination Figure 9 and Figure 10 As shown in the figure, when the air supply angle θ is greater than the limit deflection angle α of the guide vane 120, the drive component 200 drives the adjustment component 100 to move.

[0183] Reference Figure 9 (a) and Figure 10As shown in (a), when the transmission rod 22111 on the drive wheel 2211 is exactly located at the opening of the transmission groove 22211 on the first transmission wheel 2221, the adjustment assembly 100 is in its initial state. At this time, both the support plate 110 and the guide vane 120 are in their initial positions. The length direction of the support plate 110 can be parallel to the length direction of the air outlet 11, and the guide vane 120 can be parallel to the length direction of the support plate 110.

[0184] Reference Figure 9 (b) and Figure 10 As shown in (b), the drive motor 210 drives the drive wheel 2211 to rotate. When the transmission rod 22111 on the drive wheel 2211 slides along the transmission groove 22211 on the first transmission wheel 2221 to the bottom of the groove, the guide vane 120 rotates a certain angle around its own rotation axis on the support plate 110. At the same time, the support plate 110 swings a certain angle around its own rotation axis relative to the length direction of the air outlet 11. At this time, the support plate 110 can partially extend outside the air outlet 11.

[0185] Reference Figure 9 (c) and Figure 10 As shown in (c), when the transmission rod 22111 on the drive wheel 2211 slides from the bottom of the transmission groove 22211 on the first transmission wheel 2221 to the opening of the transmission groove 22211, the guide vane 120 continues to rotate around its own rotation axis by a certain angle, and the angle between the guide vane 120 and the bearing plate 110 in the length direction increases. Simultaneously, the bearing plate 110 continues to swing around its own transmission axis by a certain angle, and the angle between the bearing plate 110 and the air outlet 11 in the length direction increases. At this point, the bearing plate 110 swings to its limit deflection position, reaching its limit deflection angle. More of the bearing plate 110 extends beyond the air outlet 11.

[0186] Reference Figure 11 (d) and Figure 12 As shown in (d), when the transmission rod 22111 on the drive wheel 2211 disengages from the transmission groove 22211 on the first transmission wheel 2221, the transmission rod 22111 on the drive wheel 2211 moves away from the first transmission groove 22211 as the drive motor 210 continues to operate. At this time, the support plate 110 remains at its limit deflection position and no longer rotates. The guide vane 120 continues to rotate around its own rotation axis, and the angle between the guide vane 120 and the length direction of the support plate 110 increases.

[0187] Figure 11 This is another schematic diagram of the operation of the gear set provided in the embodiment of this application. Figure 11 This is another schematic diagram illustrating the operation of the gear set and the air guide assembly provided in the embodiments of this application.

[0188] Referring to Figure 12 Fig. 4 shows the operation of the gear set 220a when the air supply angle θ is less than the limit deflection angle a of the air guide blade 120. At this time, the drive assembly 200 only needs to drive the air guide blade 120 to rotate, and the carrier plate 110 can remain stationary at the initial position.

[0189] Referring to Figure 11 Fig. 4(a) and Figure 12 Fig. 4(b), when the transmission rod 22111 on the driving wheel 2211 is just located in the notch of the transmission groove 22211 on the first transmission wheel 2221, the adjustment assembly 100 is in the initial state. At this time, the carrier plate 110 and the air guide blade 120 are both in the initial position, and the length direction of the carrier plate 110 can be parallel to the length direction of the air outlet 11, and the air guide blade 120 can be parallel to the length direction of the carrier plate 110.

[0190] Referring to Figure 12 Fig. 4(b) and Figure 12 Fig. 4(c), the drive motor 210 drives the driving wheel 2211 to rotate reversely, and the transmission rod 22111 on the driving wheel 2211 moves away from the first transmission wheel 2221, and the air guide blade 120 rotates on the carrier plate 110 by a certain angle around its own rotation axis. At this time, the air guide blade 120 can be deflected to one end of the length direction of the air outlet 11, and this end of the air outlet 11 can correspond to the adjustment assembly 100 where the air guide blade 120 is located. Taking the adjustment assembly 100 located on the left side of the air outlet 11 as an example, the air guide blade 120 can be deflected to the left side of the air outlet 11.

[0191] Referring to Figure 13 Fig. 4(c), the drive motor 210 continues to drive the driving wheel 2211 to rotate reversely, and the transmission rod 22111 on the driving wheel 2211 continues to move away from the first transmission wheel 2221, and the air guide blade 120 continues to rotate on the carrier plate 110 by a certain angle around its own rotation axis. At this time, the air guide blade 120 can be perpendicular to the length direction of the carrier plate 110, and the air guide blade 120 remains vertically extended to the air outlet 11.

[0192] Referring to Figure 13As shown in (d) of FIG. 11, the driving motor 210 continues to drive the driving wheel 2211 to rotate reversely, and the transmission rod 22111 on the driving wheel 2211 continues to move away from the first transmission wheel 2221, so that the air guide blade 120 continues to rotate on the bearing plate 110. At this time, the air guide blade 120 can be deflected to the other end of the length direction of the air outlet 11, and the end of the air outlet 11 can be the end of the adjusting assembly 100 away from the air guide blade 120. Taking the adjusting assembly 100 on the left side of the air outlet 11 as an example, the air guide blade 120 can be deflected to the right side of the air outlet 11.

[0193] Figure 13 The exploded view of the adjusting assembly is provided for the embodiment of the present application. Referring to FIG. 12, as to how the driving assembly 200 drives all the air guide blades 120 on the bearing plate 110 to swing, as an embodiment, the adjusting assembly 100 can further comprise a linkage 130, and all the air guide blades 120 are connected with the linkage 130. When the driving assembly 200 operates, the linkage 130 can be driven to move. When the linkage 130 moves, all the air guide blades 120 can be driven to move synchronously to drive all the air guide blades 120 to swing synchronously through the linkage 130. Figure 13

[0194] Among them, the driving assembly 200 can be connected with one of all the air guide blades 120, for example, the driving assembly 200 is connected with the air guide blade 120 at the end of the bearing plate 110. The driving assembly 200 drives the air guide blade 120 to rotate, and the air guide blade 120 drives the linkage 130 connected therewith to move. In turn, through the movement of the linkage 130, all the air guide blades 120 are driven to swing synchronously.

[0195] Alternatively, the driving assembly 200 can also be connected with the linkage 130, for example, the driving assembly 200 is connected at the part of the linkage 130 between two air guide blades 120. The driving assembly 200 drives the linkage 130 to move, and the linkage 130 drives all the air guide blades 120 to swing synchronously.

[0196] Continuing to refer to FIG. 12, ​ The linkage 130 can be arranged in the bearing plate 110. In this way, the linkage 130 is connected with all the air guide blades 120. Moreover, the linkage 130 is also shielded in the bearing plate 110, so that the appearance of the air guide assembly 20 is more simple. In addition, the linkage 130 does not occupy additional separate space, and has no influence on the volume of the air guide assembly 20, which is conducive to the miniaturization of the air guide assembly 20.

[0197] ​In order to install the linkage 130 in the bearing plate 110 and facilitate the linkage 130 to be connected with each of the guide vanes 120, the bearing plate 110 can be divided into a face plate 111 and a bottom plate 112, all the guide vanes 120 can be installed on the face plate 111, and the driving assembly 200 can be installed on the bottom plate 112, and the driving assembly 200 is connected with the guide vanes 120 or the linkage 130 through the bottom plate 112. The face plate 111 and the bottom plate 112 jointly form a containing cavity, and the linkage 130 is arranged in the containing cavity.

[0198] As shown in ​ As an example, the linkage 130 can be a connecting rod 130a, the connecting rod 130a can extend along the extension direction of the bearing plate 110, and the connecting rod 130a is connected with all the guide vanes 120. The driving motor 210 can drive one of the guide vanes 120 to rotate, and the guide vane 120 drives the connecting rod 130a to reciprocate with a small swing amplitude, and through the swing and reciprocation of the connecting rod 130a, all the guide vanes 120 are driven to swing. Alternatively, the output shaft of the driving motor 210 is connected with the connecting rod 130a, and the driving motor 210 rotates to drive the connecting rod 130a to reciprocate with a small swing amplitude, and in turn drive all the guide vanes 120 to swing.

[0199] By setting the linkage 130 as the connecting rod 130a, the structure of the linkage 130 can be simplified, the processing technology of the linkage 130 is simple, the production cost is low, and it is suitable for large-scale production and application. Moreover, the connecting rod 130a is a simple and reliable transmission structure, which can effectively convert the rotary motion of the driving motor 210 into the linear reciprocating swing of the connecting rod 130a itself, and help to improve the reliability and durability of the adjusting assembly 100. In addition, the geometric characteristics of the connecting rod 130a determine that it can provide precise motion control and drive the guide vanes 120 to accurately adjust the angle within a set range to provide more accurate air supply control for the user.
