Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on October 28, 2024, with application number 202411514814.7 and application name “Air guide assembly and air treatment equipment”, all contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the technical field of air handling equipment, and in particular to an air guide blade, an adjustment component, an air guide component and air handling equipment. Background Art

[0003] Air handling equipment, such as air conditioning equipment, generally includes an air outlet and an air guide plate disposed at the air outlet. The air guide plate is rotatably connected to the air outlet, and the air supply direction of the air outlet is changed by changing the opening angle of the air guide plate relative to the air outlet.

[0004] However, the above-mentioned method of adjusting the air supply direction results in a relatively limited air supply area of ​​the air handling equipment. Summary of the invention

[0005] The present application provides an air guide blade, an adjustment component, an air guide component and an air treatment device. The air guide blade can change the air supply angle of the adjustment component, the air supply area of ​​the air guide component can be adjusted more flexibly, and the air supply coverage area of ​​the air treatment device can be expanded.

[0006] A first aspect of the present application provides an air guide blade for installation at an air outlet of an air handling device, wherein the air guide blade includes a blade body, the blade body includes a first curved portion and a second curved portion, the first curved portion and the second curved portion are respectively located on both sides of a central axis of the blade body; the first curved portion and the second curved portion are respectively bent on both sides of the thickness direction of the air guide blade, and a side of the first curved portion away from the central axis is a first air guide side, and a side of the second curved portion away from the central axis is a second air guide side.

[0007] The air guide blade provided by the present application is provided with a first curved portion and a second curved portion on the blade body, the first curved portion and the second curved portion are respectively located on both sides of the central axis of the blade body, and the first curved portion and the second curved portion are respectively bent on both sides of the thickness direction of the air guide blade. The side of the first curved portion away from the central axis is the first air guide side of the air guide blade, and the side of the second curved portion away from the central axis is the second air guide side of the air guide blade. Since the extension line of the first air guide side and the extension line of the second air guide side both have an angle with the reference plane where the blade body is located, when the air treatment device is working, no matter whether the first air guide side is outside or the second air guide side is outside, the first air guide side and the second air guide side can change the air supply angle of the adjustment component, so that the air guide component can adjust the air supply area more flexibly, thereby expanding the air supply coverage area of ​​the air treatment device.

[0008] In a possible embodiment, there is a first angle between the extension line of the first wind-guiding side and the reference plane, and there is a second angle between the extension line of the second wind-guiding side and the reference plane, the reference plane is the orthographic projection plane of the blade body, and the reference plane passes through the central axis; wherein the angle of the first angle is greater than the angle of the second angle.

[0009] In this way, when the first air guide side faces the outside of the air outlet, the angle at which the airflow deflects to the same side of the air outlet is relatively larger. When the second air guide side faces the outside of the air outlet, the angle at which the airflow deflects to the same side of the air outlet is relatively smaller. Thus, the user can adjust the opening state of the air guide blade according to actual needs to obtain different air supply directions and air supply areas. In addition, the structures on both sides of the central axis of the air guide blade are different, which facilitates the identification and installation of the air guide blade and reduces the probability of assembly rework and scrapping of the adjustment component.

[0010] In particular, when the first air guide side faces outside the air outlet and the second air guide side faces inside the air outlet, the airflow can better utilize the Coanda effect and expand the air outlet angle of the air guide blade during the process of the airflow flowing along the first curved portion to the first air guide side. At the same time, the second curved portion is close to the inside of the air outlet, and the curvature is smaller, which is more conducive to reducing airflow resistance.

[0011] In a possible implementation manner, the difference between the first angle and the second angle ranges from 6° to 12°.

[0012] In this way, there is a significant angle difference between the first angle α and the second angle β. When the air guide blade is at the same deflection angle, when the first air guide side faces the outside of the air outlet and the second air guide side faces the outside of the air outlet, the air supply direction and air supply area of ​​the adjustment component are significantly different. In addition, the angle difference between the first angle α and the second angle β is not too large, and there is no excessive bending part in the air guide blade, which can ensure the reliability and service life of the air guide blade as a whole.

[0013] In a possible embodiment, when the air guide blade is in a first open state, the first air guide side faces outside the air outlet and the second air guide side faces inside the air outlet; when the air guide blade is in a second open state, the first air guide side faces inside the air outlet and the second air guide side faces outside the air outlet.

[0014] In this way, the air guide blade can increase the air supply deflection angle by using the first air guide side, and can also increase the air supply deflection angle by using the second air guide side. There is no limit on the rotation angle of the air guide blade, the control of the air guide blade is more flexible, and the control method is simpler.

[0015] In a possible embodiment, when the air guide blade is perpendicular to the plane where the air outlet is located and the first air guide side is facing outside the air outlet, the extension line of the first air guide side extends to the same side of the air outlet; and / or, when the air guide blade is perpendicular to the plane where the air outlet is located and the second air guide side is facing outside the air outlet, the extension line of the second air guide side extends to the same side of the air outlet.

[0016] In this way, when the first air guide side faces the outside of the air outlet, when the air guide blade guides the air to the same side of the air outlet, the first air guide side can further increase the air supply deflection angle of the air guide blade. When the second air guide side faces the outside of the air outlet, when the air guide blade guides the air to the same side of the air outlet, the second air guide side can also further increase the air supply deflection angle of the air guide blade. Thus, the air supply area of ​​the adjustment component is expanded.

[0017] In a possible implementation, the angle between the extension line of the first wind guide side and the reference plane is in a range of 5°-55°, and the angle between the extension line of the second wind guide side and the reference plane is in a range of 5°-45°.

[0018] In this way, the air guide blade only needs to rotate within a small angle range to make the air guide blade have a large angle range of air supply area. In addition, the angle between the extension line of the first air guide side (or the second air guide side) and the reference plane is not too large, the bending degree of the first curved portion (or the second curved portion) is appropriate, and the air guide blade will not hinder the flow of air. The overall wind resistance of the adjustment component is very small and will not affect the air supply volume of the air handling equipment.

[0019] In a possible implementation, the angle between the extension line of the first wind guide side and the reference plane is in the range of 25°-55°, and the angle between the extension line of the second wind guide side and the reference plane is in the range of 25°-45°.

[0020] In this way, the first air guiding side (or the second air guiding side) can significantly increase the air supply deflection angle of the air guiding blade, and can better expand the air supply area of ​​the adjustment component.

[0021] In a possible implementation manner, both the first curved portion and the second curved portion are smooth curved portions, and both the first curved portion and the second curved portion have only one curved vertex.

[0022] In this way, the overall curved shape of the first curved portion (or the second curved portion) is relatively gentle, which can make the airflow flow smoothly along its surface, and will not hinder the flow of the airflow while changing the flow direction of the airflow. In addition, the first curved portion (or the second curved portion) is only bent once to one side in the thickness direction of the blade body, which avoids the first curved portion from forming a wavy surface, so as to avoid the first curved portion (or the second curved portion) changing the flow direction of the airflow multiple times, and avoid affecting the air supply direction of the air guide blade, thereby ensuring the first curved portion (or the second curved portion) The effect of adjusting the air supply deflection angle of the air guide blade is guaranteed.

[0023] In one possible embodiment, the extension line of the first wind-guiding side extends toward the first side of the reference plane, and the bending vertex of the first curved portion is located on the second side of the reference plane; and / or, the extension line of the second wind-guiding side extends toward the second side of the reference plane, and the bending vertex of the second curved portion is located on the first side of the reference plane.

[0024] The extension line of the first wind guide side (or the second wind guide side) and the bending vertex of the first curved portion (or the second curved portion) are prevented from being on the same side of the reference plane, and the first curved portion (or the second curved portion) is prevented from being excessively bent toward one side of the wind guide blade. The wind guide blade is flat as a whole, with a small degree of bending, and the wind resistance generated is small. During the long-term use of the wind guide blade, the wind guide blade has higher reliability and longer service life.

[0025] In a possible implementation manner, the blade body further includes a straight portion, and two ends of the straight portion are respectively connected to the first curved portion and the second curved portion.

[0026] In this way, the blade body can guide the air through the first curved part and the second curved part on both sides to expand the air supply coverage of the air guide blade. At the same time, the straight part in the middle part of the blade body has better smoothness, which can reduce the wind resistance in the air guide channel and increase the gas flow rate out of the air outlet. In addition, the straight part has a better effect on dispersing the air pressure, which can make the stress of the blade body more uniform and improve the reliability and service life of the blade body.

[0027] In a possible embodiment, the first end of the straight portion extends along the tangent direction of the first curved portion, and the second end of the straight portion extends along the tangent direction of the second curved portion; wherein the first end of the straight portion is connected to the first curved portion, and the second end of the straight portion is connected to the second curved portion.

[0028] In a possible implementation manner, a plurality of air outlet holes are distributed on the blade body, and the air outlet holes penetrate through both side surfaces of the blade body in the thickness direction.

[0029] In this way, part of the airflow blown out of the air duct will flow outward along the air guide channel formed between adjacent air guide blades, and another part can flow outward through the air outlet holes on the blade body. The interaction of these two parts of airflow can avoid strong wind blowing out of the air outlet, making the air supply effect of the air treatment equipment softer and improving the comfort of using the air treatment equipment.

[0030] In a possible embodiment, the air outlet extends obliquely toward the first air guide side from the first surface of the blade body to the second surface of the blade body; wherein the first surface and the second surface are the two side surfaces of the blade body in the thickness direction, and the extension line of the first air guide side extends toward the side where the first surface is located.

[0031] In this way, when the air guide blade is in the open state, in the air supply direction of the adjustment component, the angle between the extension direction of the air outlet and the side of the blade body close to the air outlet is an acute angle, and the air outlet direction of the air outlet tends to the air guide direction of the blade body. The airflow blown out of the air outlet has little effect on the overall air supply direction of the adjustment component, and the adjustment accuracy of the adjustment component on the air supply direction and air supply area can be guaranteed.

[0032] In a possible implementation manner, the angle between the extension direction of the air outlet and the reference plane is in the range of 30°-60°.

[0033] By designing the included angle between the extension direction of the air outlet and the reference plane to be less than or equal to 60°, when the adjustment component guides the air to the same side of the air outlet, the airflow blown out of the air outlet will not obviously be directed to the other side of the air outlet, and the overall adjustment effect of the adjustment component is better. In addition, the smaller the included angle between the extension direction of the air outlet and the reference plane, the closer the air outlet direction of the air outlet and the overall air supply direction of the adjustment component are.

[0034] In a possible implementation, the wind guide blade further includes a rotation shaft, which is connected to the blade body and extends along the central axis of the blade body, and the blade body rotates around the rotation shaft.

[0035] In this way, the air guide blade can be rotatably connected to the bearing plate by the rotating shaft, and the air supply direction of the adjustment component can be changed by rotating the blade body around the rotating shaft. In addition, by arranging the rotating shaft on the central axis of the blade body, the air guide blade has better stability and higher reliability, which is also beneficial to the layout design of the air guide blade, and the activity space required by the air guide blade is also minimized.

[0036] In a possible implementation manner, the air guide blade is movable between the inner side of the air outlet and the outer side of the air outlet.

[0037] In this way, the position of the air guide blade relative to the air outlet can be changed, and the interference between the air guide blade and the air duct can be significantly improved. The deflection angle of the air guide blade is less affected by the air duct, and the deflection angle range of the air guide blade can be expanded, thereby expanding the air supply coverage area of ​​the air handling equipment.

[0038] The second aspect of the present application provides an adjustment component installed at the air outlet of an air handling device, the adjustment component comprising: a supporting plate extending along the length direction of the air outlet; a plurality of air guide blades, each of which is movably connected to the supporting plate, and each of which is arranged in sequence along the surface of the supporting plate; wherein at least some of the air guide blades are the air guide blades described above.

[0039] The adjustment component provided in the present application adjusts the air supply angle of the adjustment component by sequentially arranging each air guide blade on the surface of a carrier plate and movably connecting each air guide blade to the carrier plate to change the angle between each air guide blade and a certain direction on the surface of the carrier plate.

[0040] Among them, since the adjustment component includes the aforementioned air guide blade, it has all the technical effects of the air guide blade, which will not be repeated here.

[0041] In a possible implementation, the air guide blades are arranged sequentially along the length direction of the carrying plate.

[0042] In a possible embodiment, when the first air guide side of each air guide blade is facing outward from the air outlet, the angle between the extension line of the first air guide side of each air guide blade and the reference plane gradually increases along the direction of the end close to the air outlet; and / or, when the second air guide side of each air guide blade is facing outward from the air outlet, the angle between the extension line of the second air guide side of each air guide blade and the reference plane gradually increases along the direction of the end close to the air outlet.

[0043] In this way, the air supply deflection angle of the regulating component gradually increases from the center of the air outlet to the end of the air outlet, the air supply area of ​​the regulating component is larger, and the air supply coverage is wider. In addition, the air supply area gradually expands outward, the air volume is more dispersed, and the air supply is softer.

[0044] The third aspect of the present application provides an air guide assembly installed at the air outlet of an air handling device, the air guide assembly comprising: an adjustment assembly as described above; a first drive assembly, connected to the adjustment assembly, and driving each air guide blade in the adjustment assembly to change position relative to a supporting plate.

[0045] The air guide assembly provided in the present application drives each air guide blade to move by setting a first driving assembly to change the angle between each air guide blade and a certain direction on the plate surface of the supporting plate, thereby adjusting the air supply angle of the adjusting assembly.

[0046] Among them, since the air guide component includes the aforementioned air guide blades, it has all the technical effects of the air guide blades, which will not be repeated here.

[0047] In a possible implementation, the first driving assembly also drives the carrying plate in the adjusting assembly to move.

[0048] In this way, the first driving component not only drives the air guide blades on the bearing plate to move, but also drives the air guide blades to move together with the bearing plate. In this way, the air supply angle of the air guide component can be flexibly adjusted, the air supply area of ​​the air guide component can be expanded, and the air supply coverage area of ​​the air guide component is larger, which can realize air supply over a large area. The indoor temperature can be adjusted more quickly, the indoor temperature uniformity can be improved, and the indoor comfort can be enhanced.

[0049] Furthermore, by driving both the air guide blades and the bearing plate to move through the first driving component, the driving method of the air guide component is simplified, the number of driving components and the occupied space can be reduced, and the energy consumption of the air guide component is reduced.

[0050] In a possible implementation, there are two adjustment components, and the two adjustment components are spaced apart along the length direction of the air outlet.

[0051] In this way, the two regulating components can supply air to different areas respectively, which can expand the air supply area of ​​the air guide component and the air supply coverage area of ​​the air handling equipment. In addition, the temperature of the entire indoor space can be adjusted more evenly, reducing the temperature difference in the room and the discomfort caused by strong winds in local areas, thereby improving the overall comfort of the room. In addition, the air handling equipment can achieve the cooling or heating target in a shorter time and with higher energy efficiency.

[0052] In a possible implementation, the air guide assembly further includes at least one second drive assembly, the second drive assembly is connected between two adjacent adjustment assemblies, and the second drive assembly simultaneously drives the bearing plates in the two adjustment assemblies to move.

[0053] By setting the first drive assembly to drive the wind guide blades and the second drive assembly to drive the carrier plate, the first drive assembly and the second drive assembly respectively drive a moving object, the driving method is relatively simple, the structural design of the first drive assembly and the second drive assembly can also be relatively simple, and the design costs of both can be reduced. In addition, the first drive assembly and the second drive assembly do not affect each other, and the operation reliability of the wind guide assembly is higher.

[0054] A fourth aspect of the present application provides an air handling device, comprising a device body and an air guide assembly as described above.

[0055] The air handling equipment provided in the present application includes the aforementioned air guide component and thus has all the technical effects of the air guide component, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] As described in the background technology, conventional air conditioners are equipped with swingable air guide plates in the air duct to adjust the air supply angle. For example, the horizontally arranged air guide plates swing up and down to achieve up and down air sweeping, and the vertically arranged air guide plates swing left and right to achieve left and right air sweeping. Among them, the swing angles of all air guide plates are uniformly controlled by connecting rods, thereby adjusting the overall air supply area of ​​the air conditioner.

[0081] However, in the above-mentioned method of adjusting the air supply area, the area size of the air supply area is positively correlated with the area size of the air outlet, which will result in a relatively limited air supply area for the air conditioner, a small air supply coverage area, and inability to achieve air supply over a large area.

[0082] In view of this, an embodiment of the present application provides an air guide blade, an adjustment component, an air guide component and an air treatment device. The air guide component is installed at the air outlet of the air treatment device. The air guide component includes at least one adjustment component. Each adjustment component is provided with multiple air guide blades. The air supply area of ​​the air treatment device is adjusted by swinging the air guide blades.

[0083] By designing at least part of the air guide blade, a first curved portion and a second curved portion are provided on the blade body of the air guide blade, the first curved portion and the second curved portion are respectively located on both sides of the central axis of the blade body, and the first curved portion and the second curved portion are respectively bent on both sides of the thickness direction of the air guide blade. The side of the first curved portion away from the central axis is the first air guide side of the air guide blade, and the side of the second curved portion away from the central axis is the second air guide side of the air guide blade. Since the extension line of the first air guide side and the extension line of the second air guide side both have an angle with the reference plane where the blade body is located, when the air treatment device is working, no matter the first air guide side is outside or the second air guide side is outside, the first air guide side and the second air guide side can change the air supply angle of the adjustment component, so that the air guide component can adjust the air supply area more flexibly, thereby expanding the air supply coverage area of ​​the air treatment device.

[0084] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0085] The embodiment of the present application provides an air treatment device, which includes but is not limited to air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air equipment. In the embodiment of the present application, the air treatment equipment is an air conditioning equipment as an example for description. Among them, the air conditioning equipment may include a wall-mounted air conditioner, a vertical air conditioner, a central air conditioner, a split air conditioner, a mobile air conditioner, a window air conditioner, a duct air conditioner, etc.

[0086] The following description will be specifically made by taking the air handling equipment being a wall-mounted air conditioner as an example.

[0087] Figure 1 This is a schematic diagram of the structure of an air treatment device provided in an embodiment of the present application. Figure 1As shown, the air treatment device 1 includes a device body 10, and the device body 10 has an air outlet 11, and the air treatment device 1 supplies air to the outside through the air outlet 11. Taking a wall-mounted air conditioner as an example, the air treatment device 1 is installed on a wall in the room, and the air outlet 11 can be set on the front side (the side surface facing away from the wall) of the device body 10 and close to the lower part. For example, the air outlet 11 can be set tilted downward, and the air supply area of ​​the air treatment device 1 is more appropriate.

[0088] An air guide assembly 20 is provided at the air outlet 11 of the device body 10 , and the air supply direction and air supply area of ​​the air treatment device 1 are adjusted by the air guide assembly 20 to achieve flexible air supply of the air treatment device 1 .

[0089] Figure 2 A three-dimensional structural diagram from one perspective of an air guide assembly provided in an embodiment of the present application.

[0090] Figure 3 for Figure 2 A three-dimensional structural diagram of the air guide component from another perspective.

[0091] Reference Figure 2 As shown, the air guide assembly 20 includes an adjustment assembly 100, and the adjustment assembly 100 is arranged in the air duct of the device body 10. The air duct has an installation base for the adjustment assembly 100, and the adjustment assembly 100 can be installed on the installation base. In addition, 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 supply direction and air supply area of ​​the device body 10 can be adjusted by the adjustment assembly 100.

[0092] For ease of explanation, this embodiment defines a basic air duct wall 12 (see Figure 1 As shown in the figure, the basic air duct wall 12 is, for example, a side wall of the air duct close to the wall, and the adjustment component 100 can be installed on the basic air duct wall 12. The adjustment component 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.

[0093] The adjustment assembly 100 may include a carrier plate 110 and a plurality of wind guide blades 120. The carrier plate 110 may be mounted on the basic air duct wall 12, and the plate surface of the carrier plate 110 may be, for example, parallel to the wall surface of the basic air duct wall 12. In addition, the carrier plate 110 may extend along the length direction of the air outlet 11, so that the adjustment assembly 100 can cover the air outlet 11. The wind guide blades 120 are sequentially arranged along the plate surface of the carrier plate 110, and the wind guide blades 120 are movably connected to the carrier plate 110.

[0094] The carrier plate 110 is close to the basic air duct wall 12, so that the adjustment assembly 100 can be installed on the basic air duct wall 12 through the carrier plate 110. The air guide blade 120 can be located on a side of the carrier plate 110 away from the basic air duct wall 12, and the air guide blade 120 faces the air outlet 11, and the air guide blade 120 extends 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 blade 120, so that the airflow is guided by the air guide blade 120.

[0095] Reference Figure 3 As shown, the air guide assembly 20 further includes a driving mechanism 200, which is connected to the adjustment assembly 100. The adjustment assembly 100 is driven to move by the driving mechanism 200, so as to adjust the air supply direction and air supply area by the adjustment assembly 100.

[0096] The driving mechanism 200 is at least used to drive the air guide blades 120 of the adjustment component 100 to move, so that the position of each air guide blade 120 changes relative to the carrier plate 110. The angle between each air guide blade 120 and a certain direction on the plate surface of the carrier plate 110 changes, and each air guide blade 120 is uniformly deflected toward one side of the air outlet 11 to adjust the air supply angle of the adjustment component 100.

[0097] On this basis, the carrier plate 110 can be movably connected to the basic air duct wall 12, and the driving mechanism 200 can also be used to drive the carrier plate to move. The driving mechanism 200 drives the carrier plate 110 to move, so that the position of the carrier plate 110 relative to the air outlet 11 changes, and the distance between the carrier plate 110 and the basic air duct wall 12 changes.

[0098] The air guide blades 120 on the carrier plate 110 move together with the carrier plate 110, and the position of the air guide blades 120 relative to the air outlet 11 can be changed. The carrier plate 110 can move toward the outside of the air outlet 11, and some or even all of the air guide blades 120 on the carrier plate 110 can extend out of the air outlet 11. In this way, the interference phenomenon between the air guide blades 120 and the air duct is significantly improved, and the deflection angle restriction of the air duct on the air guide blades 120 can be weakened or even eliminated, and the deflection angle range of the air guide blades 120 can be further expanded.

[0099] In this way, the driving mechanism 200 not only drives the air guide blades 120 on the carrier plate 110 to move, but also drives the air guide blades 120 to move together with the carrier plate 110, so that the driving mechanism 200 drives the adjustment component 100 more flexibly. In this way, the air supply angle of the air guide component 20 can be flexibly adjusted, the air supply area of ​​the air guide component 20 can be expanded, and the air supply coverage area of ​​the air guide component 20 is larger, which can realize air supply over a large area. The indoor temperature can be adjusted more quickly, the indoor temperature uniformity can be improved, and the indoor comfort can be improved.

[0100] Furthermore, the air guide assembly 20 can deliver air to more areas, which can improve the adjustment accuracy of the air guide assembly 20 on the air supply area. Furthermore, by adjusting the air supply angle of the air guide assembly 20 through the driving mechanism 200, the air supply area of ​​the air guide assembly 20 can be kept away from the user's activity area, thereby avoiding physical discomfort or health problems caused by cold air blowing directly on the user. The air supply angle of the air guide assembly 20 can also be driven by the driving mechanism 200 to change continuously, thereby avoiding the air guide assembly 20 blowing directly on a certain area for a long time, thereby improving the uniformity of the overall indoor temperature.

[0101] In this embodiment, the driving mechanism 200 drives the carrier plate 110 to move in a swinging manner, and the carrier plate 110 can swing around its own rotation axis on the basic air duct wall 12 (can also be considered as rotating). In addition, the position of the carrier plate 110 relative to the air outlet 11 is changed, and the angle of the carrier plate 110 relative to the plane direction of the air outlet 11 is changed. With a certain end of the carrier plate 110 away from its own rotation axis as a reference, the end of the carrier plate 110 swings toward the direction close to the air outlet 11 (for example, the end of the carrier plate 110 extends out of the air outlet 11), or the end of the carrier plate 110 swings toward the direction away from the air outlet 11 (for example, the end of the carrier plate 110 is retracted into the air outlet 11).

[0102] In this way, the driving mechanism 200 not only drives the air guide blade 120 to swing relative to the carrier plate 110, but also changes the angle between the air guide blade 120 and a certain direction of the plate surface of the carrier plate 110, and adjusts the air supply direction by the swing of the air guide blade 120 itself. In addition, the driving mechanism 200 also drives the carrier plate 110 to swing relative to the air outlet 11, and the deflection angle of the carrier plate 110 is superimposed on the deflection angle of the air guide blade 120 to adjust the air supply direction. In this way, the air supply angle range of the adjustment component 100 is increased, the air supply area of ​​the adjustment component 100 is expanded, and the air supply coverage area of ​​the air treatment device 1 is larger.

[0103] Of course, in other embodiments, the driving mechanism 200 may drive the carrier plate 110 to move in a translational manner, the length direction of the carrier plate 110 is always consistent with the length direction of the air outlet 11, and the carrier plate 110 translates on the basic air duct wall 12 along its own width direction. In addition, the position of the carrier plate 110 relative to the air outlet 11 is changed. For example, the carrier plate 110 moves from a position accommodated in the air duct toward the direction of the air outlet 11, for example, the carrier plate 110 moves to the plane where the air outlet 11 is located, or even the carrier plate 110 extends out of the air outlet 11 as a whole. Alternatively, the carrier plate 110 moves from a position located in the plane where the air outlet 11 is located or outside the air outlet 11 toward the air duct, so that the carrier plate 110 is recovered into the air duct.

[0104] In this way, the driving mechanism 200 can drive the carrier plate 110 to move toward the air outlet 11, so that the air guide blades 120 on the carrier plate 110 are closer to the air outlet 11, or even extend out of the air outlet 11. It can avoid the air duct from limiting the swing range of the air guide blades 120, and increase the deflection angle range of the air guide blades 120. Furthermore, the air supply area of ​​the adjustment component 100 is expanded, and the air supply coverage area of ​​the air treatment device 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 component 20 is toward the edge of the air outlet 11, it can also avoid the air duct from obstructing the air supply of the air guide component 20, and avoid causing turbulence in the air supply airflow.

[0105] The following description is made by taking the example that the driving mechanism 200 drives the supporting plate 110 to swing on the basic air duct wall 12 .

[0106] Reference Figure 2 or Figure 3 As for the air guiding method of the air guiding assembly 20, as an implementation method, the air guiding assembly 20 can be used to achieve left and right air sweeping. At this time, the air guiding blades 120 installed on the carrier plate 110 can be arranged in sequence along the length direction of the carrier plate 110, and the air flow blown out of the air duct is guided through the air guiding channel formed between the two adjacent air guiding blades 120 on the left and right. Each air guiding blade 120 can swing to the two ends of the length direction of the air outlet 11, or it can be said that each air guiding blade 120 swings to the left and right ends of the air outlet 11, so as to guide the air flow to the left or right side of the air outlet 11.

[0107] For example, each wind guide blade 120 can be rotatably connected to the carrier plate 110. The rotation axis of each wind guide blade 120 can be perpendicular to the plate surface of the carrier plate 110, and the blade surface of each wind guide blade 120 can also be perpendicular to the plate surface of the carrier plate 110. The driving mechanism 200 can drive each wind guide blade 120 to rotate along its own rotation axis, so that all the wind guide blades 120 can swing uniformly toward the left and right ends of the air outlet 11.

[0108] In other embodiments, the air guide assembly 20 can also be used to achieve upward and downward sweeping. In this case, the air guide blades 120 installed on the carrier plate 110 can be arranged in sequence along the width direction of the carrier plate 110, and the air flow blown out of the air duct is guided through the air guide channel formed between the two upper and lower adjacent air guide blades 120. Each air guide blade 120 can swing toward both ends of the height direction (or width direction) of the air outlet 11, or it can be said that each air guide blade 120 swings toward the upper and lower ends of the air outlet 11 to achieve the purpose of guiding the air flow to the upper or lower side of the air outlet 11.

[0109] Exemplarily, each wind guide blade 120 can also be rotatably connected to the carrier plate 110. The rotation axis of each wind guide blade 120 can be parallel to the board surface of the carrier plate 110, and the wind guide blade 120 can be connected to the carrier plate 110 through a support. For example, the two ends of the extension direction of the wind guide blade 120 are its rotation axis, and the rotation axes at both ends of the wind guide blade 120 are rotatably connected to the carrier plate 110 through a support, and there is a gap between the wind guide blade 120 and the board surface of the carrier plate 110. The driving mechanism 200 can drive each wind guide blade 120 to rotate along its own rotation axis, so that all the wind guide blades 120 can swing uniformly toward the upper and lower ends of the air outlet 11.

[0110] In other embodiments, the air guide assembly 20 can also be used to achieve wind sweeping in different directions. For example, the air guide assembly 20 can achieve both left and right wind sweeping and up and down wind sweeping. In other words, each air guide blade 120 can swing toward both ends (left and right ends) in the length direction of the air outlet 11, and each air guide blade 120 can swing toward both ends (upper and lower ends) in the height direction of the air outlet 11.

[0111] Exemplarily, each wind guide blade 120 can also be rotatably connected to the carrier plate 110. Since the wind guide assembly 20 can achieve wind sweeping in different directions, each wind guide blade 120 can have a rotation axis in different directions. For example, each wind guide blade 120 has a rotation axis perpendicular to the board surface of the carrier plate 110, and each wind guide blade 120 has a rotation axis parallel to the board surface of the carrier plate 110. All wind guide blades 120 are installed on the carrier plate 110 in the form of a wind guide group, for example, each wind guide group includes a plurality of wind guide blades 120, each wind guide group is rotatably connected to the carrier plate 110 via a rotation axis perpendicular to the board surface of the carrier plate 110, and each wind guide blade 120 in each wind guide group is provided with a rotation axis parallel to the board surface of the carrier plate 110.

[0112] The following uses the example of the air guide assembly 20 being used to achieve left and right wind sweeping, where each air guide blade 120 is arranged in sequence along the length direction of the carrier plate 110, each air guide blade 120 is rotatably connected to the carrier plate 110, and the rotation axis of each air guide blade 120 is perpendicular to the plate surface of the carrier plate 110 for explanation.

[0113] Continue to refer to Figure 2 or Figure 3 As for the number of adjustment components 100 in the air guide component 20, as an implementation, the number of adjustment components 100 can be two, and the two adjustment components 100 can be arranged at intervals along the length direction of the air outlet 11. Under the drive of the driving mechanism 200, the air guide blades 120 of the two adjustment components 100 can deflect relative to their respective bearing plates 110, and the bearing plates 110 of the two adjustment components 100 can also deflect relative to the air outlet 11.

[0114] By arranging two adjustment components 100 at intervals along the length direction of the air outlet 11, the two adjustment components 100 can respectively supply air to different areas. The two adjustment components 100 respectively have different air supply areas, which can expand the air supply area of ​​the air guide component 20 and expand the air supply coverage area of ​​the air treatment device 1.

[0115] Taking the paper direction in the figure as an example, the adjustment assembly 100 on the left is driven by the driving mechanism 200 to deflect the air guide blade 120 of the adjustment assembly 100 to the left, and the adjustment assembly 100 on the right is driven by the driving mechanism 200 to deflect the air guide blade 120 of the adjustment assembly 100 to the right, so that the overall air supply area of ​​the air guide assembly 20 is expanded. On this basis, if the driving mechanism 200 drives the bearing plate 110 in the left adjustment assembly 100 to deflect to the left and the bearing plate 110 in the right adjustment assembly 100 to deflect to the right, the overall air supply area of ​​the air guide assembly 20 will be further expanded.

[0116] With this setting, the air conditioner has a larger air supply coverage area, which can adjust the temperature of the entire indoor space more evenly, reduce the temperature difference in the room, and improve the overall comfort of the room. In addition, a larger air supply coverage area can also enable the air conditioner to reach the set temperature target faster. The air conditioner can complete the cooling target or heating target in a shorter time, and the air conditioner is more energy efficient. In addition, a larger air supply coverage area makes the air flow distribution area of ​​the air conditioner wider and the air flow rate smoother, which can reduce the discomfort caused by strong winds in local areas, provide a soft air supply effect, and make users feel more natural and comfortable in the air-conditioned environment.

[0117] As another embodiment, the air guide assembly 20 may also include only one adjustment assembly 100. Under the drive of the driving mechanism 200, the air guide blade 120 of the adjustment assembly 100 can deflect relative to the carrier plate 110, and the carrier plate 110 can also deflect relative to the air outlet 11. Therefore, one adjustment assembly 100 also has a sufficiently large air supply area to meet the general indoor space requirements.

[0118] For example, when the air treatment device 1 is used in a living space, the indoor space is small, and only one adjustment component 100 can also meet the indoor space requirements. Alternatively, when the deflection angle range of the air guide blade 120 of the adjustment component 100 is large, the deflection angle range of the bearing plate 110 is also large, and the air guide blade 120 and the bearing plate 110 are superimposed so that the adjustment component 100 has a large air supply area, one adjustment component 100 can also meet the air supply requirements of a large space, and the air guide component 20 can only be provided with one adjustment component 100.

[0119] Of course, in other embodiments, the air guide assembly 20 may also include more than three adjustment assemblies 100, and each adjustment assembly 100 is sequentially arranged along the length direction of the air outlet 11. The driving mechanism 200 drives the air guide blades 120 of each adjustment assembly 100 to deflect relative to their respective bearing plates 110, and the driving mechanism 200 also drives the bearing plates 110 of each adjustment assembly 100 to deflect relative to the air outlet 11.

[0120] For example, when the air handling device 1 is relatively large and has an air outlet 11 with a relatively long length, multiple adjustment components 100 can be sequentially arranged at intervals along the length direction of the air outlet 11, and each adjustment component 100 maintains a suitable length to meet the stability and reliability requirements of the adjustment component 100. Alternatively, when the air handling device 1 is used in a relatively large space such as an office or a factory, multiple adjustment components 100 can be arranged so that the air guide component 20 has a larger air supply coverage area to meet the air supply requirements of the large space.

[0121] Reference Figure 3 As shown, in order to realize that the driving mechanism 200 can drive each air guide blade in the adjustment assembly to deflect relative to the bearing plate, and can also drive the bearing plate to deflect relative to the air outlet, the driving mechanism 200 may include a first driving assembly 210, the first driving assembly 210 is connected to the adjustment assembly, and the first driving assembly 210 is at least used to drive each air guide blade in the adjustment assembly to deflect relative to the bearing plate.

[0122] The first driving assembly 210 and the adjusting assembly can be arranged in a one-to-one correspondence. When the wind guide assembly includes more than two adjusting assemblies, the driving mechanism 200 can also include more than two first driving assemblies 210, and each first driving assembly 210 is correspondingly connected to each adjusting assembly, so that the first driving assembly 210 drives the corresponding adjusting assembly to move.

[0123] Reference Figure 3As shown, in some embodiments, when the air guide assembly includes more than two adjustment assemblies, the driving mechanism 200 may further include at least one second driving assembly 220, and the second driving assembly 220 may be connected between two adjacent adjustment assemblies. In this case, the first driving assembly 210 may only be used to drive each air guide blade to deflect relative to the bearing plate, and the bearing plates in the two adjustment assemblies connected on both sides thereof are driven to move by the second driving assembly 220.

[0124] When the air guide assembly includes two adjustment assemblies, the drive mechanism 200 may be provided with only one second drive assembly 220. The second drive assembly 220 is connected between the two adjustment assemblies, and the second drive assembly 220 may drive the supporting plates of the two adjustment assemblies to move relative to each other.

[0125] When the air guide assembly includes more than three adjustment assemblies, a second drive assembly 220 may be provided between each two adjacent adjustment assemblies, and the second drive assembly 220 drives the bearing plates of the adjacent adjustment assemblies to move relative to each other. Alternatively, only one second drive assembly 220 may be provided between two adjacent adjustment assemblies, and other adjacent adjustment assemblies may be connected via a transmission structure, and the driving force of the second drive assembly 220 may be transmitted via the transmission structure, so that the bearing plates of all the adjustment assemblies can move.

[0126] By setting the first drive assembly 210 to drive the wind guide blades and the second drive assembly 220 to drive the carrier plate, the first drive assembly 210 and the second drive assembly 220 respectively drive a moving object, the driving method is relatively simple, and the structural design of the first drive assembly 210 and the second drive assembly 220 can also be relatively simple. In this way, the design difficulty of the first drive assembly 210 and the second drive assembly 220 is relatively low, and the design cost of both can be reduced. In addition, the first drive assembly 210 and the second drive assembly 220 do not affect each other. Even if one of them fails and cannot work, it does not affect the work of the other. The probability that both the wind guide blades and the carrier plate cannot move is low, and the operation reliability of the wind guide assembly is higher.

[0127] In other embodiments, the driving mechanism 200 may include only the first driving assembly 210, and the first driving assembly 210 is used to drive the air guide blades of the adjustment assembly to deflect relative to the bearing plate, and the first driving assembly 210 is used to drive the bearing plate to deflect relative to the air outlet. In this case, no matter how many adjustment assemblies the air guide assembly includes, only one first driving assembly 210 is required to be provided for each adjustment assembly.

[0128] When the air guide assembly includes more than two adjustment assemblies, each adjustment assembly is independently driven by the first drive assembly 210, and there is no linkage relationship between the adjustment assemblies, and the air supply area of ​​each adjustment assembly can be independently adjusted. In this way, the air handling equipment can be suitable for different indoor layouts and usage requirements, and the user can flexibly adjust the air supply area of ​​the two adjustment assemblies according to actual conditions. In order to meet the needs of different environments for different air supply areas, the airflow blown out by the air handling equipment can be fully and effectively utilized to avoid waste.

[0129] As for the structural design of the first driving component 210, refer to Figure 3 As shown, when the first driving assembly 210 only drives the air guide blades on the carrier plate to move, the first driving assembly 210 may include only one driving motor 201. The output shaft of the driving motor 201 may be directly transmitted to the air guide blades, or the output shaft of the driving motor 201 may be transmitted to the air guide blades after being reduced in speed and increased in torque through a reduction gear.

[0130] When the first driving assembly 210 drives the air guide blade and the carrier plate at the same time, as an implementation method, the first driving assembly 210 can be provided with two driving motors 201, one of which is driven to the air guide blade, and the other is driven to the carrier plate. In this way, the two driving motors 201 do not affect each other, and even if one fails and cannot work, it does not affect the work of the other, and the probability that both the air guide blade and the carrier plate cannot move is low, and the operation reliability of the adjustment assembly is higher.

[0131] When the first driving assembly 210 drives the air guide blades and the carrier plate at the same time, as another embodiment, the first driving assembly 210 may also be provided with only one driving motor 201. The output shaft of the driving motor 201 may be directly transmitted to the air guide blades, and the output shaft of the driving motor 201 is transmitted to the carrier plate through a transmission structure, so as to drive the air guide blades and the carrier plate to move simultaneously through one driving motor 201. Exemplarily, the transmission structure may be a gear set, the driving motor 201 directly drives the air guide blades to rotate, and the driving motor 201 drives the carrier plate to swing through the gear set.

[0132] As for the structural design of the second driving component 220, Figure 2 and Figure 3 As shown, the second drive assembly 220 may include a drive motor 201 and a transmission member 221, wherein the drive motor 201 is in transmission connection with the transmission member 221, and the transmission member 221 is connected between the bearing plates of two adjacent adjustment assemblies. The drive motor 201 drives the transmission member 221 to move, and the transmission member 221 drives the two bearing plates to move relative to each other.

[0133] Exemplarily, the transmission member 221 may include a push-pull rod 2211 and two connecting rods 2212. The drive motor 201 is in transmission connection with the push-pull rod 2211. One end of the two connecting rods 2212 are both connected to the push-pull rod 2211, and the other ends of the two connecting rods 2212 are respectively connected to the two supporting plates. The drive motor 201 drives the push-pull rod 2211 to move in the plane direction where the plate surface of the supporting plate is located, so that the push-pull rod 2211 drives the two connecting rods 2212 to move relative to each other, and then drives the two supporting plates to swing relative to each other.

[0134] Figure 4 A decomposition structure diagram of the adjustment component provided in the embodiment of the present application. Figure 4 As shown, in order to realize that the first driving assembly 210 drives all the air guide blades on the carrier plate to swing, the adjustment assembly can also be provided with a linkage 130, and all the air guide blades are connected to the linkage 130. When the first driving assembly 210 is running, the linkage 130 can be driven to move, so that all the air guide blades can be driven to swing synchronously through the linkage 130.

[0135] The first driving assembly 210 may be connected to one of the air guide blades disposed on the carrier plate, for example, the first driving assembly 210 is connected to the air guide blade located at one end of the carrier plate in the length direction. The first driving assembly 210 drives the air guide blade to rotate, and the air guide blade drives the linkage member 130 connected thereto to move. Furthermore, the linkage member 130 drives all the air guide blades to swing synchronously.

[0136] Alternatively, the first drive assembly 210 may also be connected to the linkage 130, for example, the first drive assembly 210 is connected to the portion of the linkage 130 between two wind guide blades. The first drive assembly 210 drives the linkage 130 to move, and the linkage 130 drives all wind guide blades to swing synchronously.

[0137] Continue to refer to Figure 4 , the linkage member 130 can be arranged in the carrier plate. In this way, it is convenient for the linkage member 130 to be connected with all the wind guide blades. Moreover, the linkage member 130 is also shielded in the carrier plate, making the appearance of the adjustment component more concise. In addition, the linkage member 130 does not occupy an additional separate space, has no effect on the volume of the adjustment component, and is conducive to the thinning of the adjustment component.

[0138] In order to install the linkage member 130 in the carrier plate 110 and facilitate the connection between the linkage member 130 and each wind guide blade, the carrier plate 110 can be divided into two parts: a panel 111 and a bottom plate 112. The panel 111 and the bottom plate 112 together form a receiving cavity, and the linkage member 130 is arranged in the receiving cavity. All wind guide blades can be installed on the panel 111, and the first drive assembly 210 can be installed on the bottom plate 112, and the first drive assembly 210 passes through the bottom plate 112 to connect with the wind guide blade or the linkage member 130.

[0139] like Figure 4 As shown, as an example, the linkage 130 may be a connecting rod 130a, which may extend along the extension direction of the carrier plate 110, and the connecting rod 130a is connected to all the air guide blades 120. The driving motor 201 of the first driving assembly 210 may drive one of the air guide blades 120 to rotate, and the air guide blade 120 drives the connecting rod 130a to reciprocate with a smaller swing amplitude, and through the swinging and reciprocating motion of the connecting rod 130a, all the air guide blades 120 are driven to swing. Alternatively, the output shaft of the driving motor 201 is connected to the connecting rod 130a, and the driving motor 201 rotates to drive the connecting rod 130a to reciprocate with a smaller swing amplitude, thereby driving all the air guide blades 120 to swing.

[0140] 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. In addition, the connecting rod 130a is a simple and reliable transmission structure, which can effectively convert the rotational motion of the drive motor 201 into the linear reciprocating swing of the connecting rod 130a itself, which helps to improve the reliability and durability of the adjustment component 100. In addition, the geometric characteristics of the connecting rod 130a determine that it can provide precise motion control, and can drive the air guide blade 120 to accurately adjust the angle within a set range, so as to provide users with more precise air supply control.

[0141] As another example, the linkage member may be a rack (not shown in the figure), and the rack may extend along the extension direction of the carrier plate 110. Each wind guide blade 120 includes a gear (not shown in the figure), and the gear may be, for example, disposed on the central axis of the wind guide blade 120. The output shaft of the drive motor 201 in the first drive assembly 210 may also be connected to a gear (for example, the output shaft of the drive motor 201 is connected to a gear on one of the wind guide blades 120). The drive motor 201 drives the rack to move along the extension direction of the carrier plate 110 through the gear, and the movement of the rack drives the gears on each wind guide blade 120 to rotate, thereby driving all the wind guide blades 120 to rotate.

[0142] Compared with the connecting rod 130a, the transmission is transmitted by meshing the rack and the gear. Since the rotation of the gear does not limit the rotation angle range, as long as the rack is long enough and the rack moves continuously, the gear can be driven to achieve 360° rotation. Therefore, the gear can drive the air guide blade 120 to achieve a rotation angle range of 0° to 360°, and can achieve all-round wind sweeping. In addition, the rack moves in a linear manner, the transmission method is simpler, the motion trajectory is more precise, the reliability of driving the air guide blade 120 to rotate is higher, and the rotation angle of the air guide blade 120 can be more accurately controlled.

[0143] Figure 5 Another exploded structural diagram of the adjustment component provided in the embodiment of the present application. Figure 5 As shown, the wind guide blade 120 includes a blade body 121, which is the main structure of the wind guide blade 120. An air guide channel is formed between the blade bodies 121 of adjacent wind guide blades 120 to guide the airflow blown out of the air outlet 11. The wind guide blade 120 is driven to move by the first driving assembly 210 to change the direction of the blade body 121 of the wind guide blade 120, thereby changing the air supply direction of the adjustment assembly 100.

[0144] The thickness of the blade body 121 can be between 2 mm and 3 mm. In this way, the blade body 121 has a certain thickness, which meets the processability requirements of the blade body 121 and can ensure the structural strength required by the blade body 121. At the same time, the thickness of the blade body 121 is also small, the space occupied by the blade body 121 is small, and there is sufficient spacing between adjacent blades, so that the airflow in the air duct can be smoothly guided out to avoid affecting the air outlet of the air treatment device 1.

[0145] Illustratively, the thickness of the blade body 121 may be 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3.0 mm, etc.

[0146] When the wind guide blade 120 is rotatably connected to the carrier plate 110, the wind guide blade 120 may further include a rotation shaft 122. The rotation shaft 122 is connected to the blade body 121, and the rotation shaft 122 may be integrally formed on the blade body 121 to form an integrally formed wind guide blade 120. The rotation shaft 122 may be connected to one end of the blade body 121 facing the carrier plate 110, and the rotation shaft 122 is rotatably connected to the carrier plate 110, and the blade body 121 rotates around the rotation shaft 122.

[0147] Exemplarily, the rotating shaft 122 can be located on the central axis of the blade body 121. In this way, the force balance of the air guide blade 120 is good, and the air guide blade 120 has better stability and higher reliability during the rotation process. In addition, the width of the blade body 121 on both sides of the central axis is consistent, which is more conducive to the layout and installation of the air guide blade 120. The spacing between adjacent blades can be designed according to the width of the blade body 121, so that each air guide blade 120 is evenly spaced. In addition, the air guide blade 120 can also be better used in the 360° rotation scenario. The range of movement of the air guide blade 120 is the smallest, and the activity space required by the air guide blade 120 is also the smallest. The space occupied by the air guide assembly 20 can be reduced, which is conducive to the miniaturization of the air treatment equipment 1.

[0148] Exemplarily, the rotating shaft 122 may include a disc structure (not shown in the figure), and a mounting groove (not shown in the figure) may be provided on the bearing plate 110, and the disc structure may rotate in the mounting groove to realize the rotation of the wind guide blade 120 on the bearing plate 110. The disc structure may be completely accommodated in the mounting groove. For example, the disc structure is flush with the front surface of the bearing plate 110 (the side surface of the bearing plate 110 facing the blade body 121). In this way, the disc structure will not protrude on the surface of the bearing plate 110, which helps to reduce the wind resistance of the adjustment component 100. In addition, the adjustment component 100 has better flatness and is more beautiful.

[0149] Figure 6 for Figure 2 Front view of the air guide assembly in FIG. Figure 7 for Figure 6 A partial enlarged view of the wind guide blade at A in a vertical state. Figure 6 and Figure 7 As shown, this embodiment also designs the shape of the air guide blade 120 in the adjustment component 100, and further adjusts the air supply direction through the air guide blade 120, thereby enhancing the flexibility of the adjustment component 100 in adjusting the air supply area, so as to further expand the air supply coverage area of ​​the air guide component 20.

[0150] For ease of description, in this embodiment, the two opposite sides of the blade body 121 of the air guide blade 120 are respectively defined as a first air guide side 1211 and a second air guide side 1212, and the first air guide side 1211 and the second air guide side 1212 are respectively located on both sides of the central axis of the blade body 121. When the air treatment device 1 is in operation and the air guide blade 120 is in a state of opening the air outlet 11, one of the first air guide side 1211 and the second air guide side 1212 of the blade body 121 is located at an inner position of the air outlet 11, and the other is located at an outer position of the air outlet 11.

[0151] Specifically, in this embodiment, the blade body 121 of at least part of the wind guide blades 120 in the adjustment assembly 100 is set to a curved surface shape. For these curved blade bodies 121, the central axis of the blade body 121 is used as a dividing line, and the blade body 121 is a first curved portion 1213 on one side of the central axis of the blade body 121, and the first wind guide side 1211 is a side of the first curved portion 1213 away from the central axis of the blade body 121.

[0152] By designing the blade body 121 as a first curved portion 1213 on one side of the central axis, the first curved portion 1213 causes the first wind-guiding side 1211 to deflect toward one side of the blade body 121. With reference to the reference plane A of the blade body 121, the extension direction of the first wind-guiding side 1211 deviates from the reference plane A, and a first angle α is formed between the extension line of the first wind-guiding side 1211 and the reference plane A (see Figure 7 shown).

[0153] The reference plane A of the blade body 121 is the orthographic projection plane of the blade body 121, and the orthographic projection plane is a projection plane formed by orthographically projecting the blade body 121. In addition, the reference plane A of the blade body 121 includes the central axis of the blade body 121, or in other words, the central axis of the blade body 121 passes through the reference plane A. It can be understood that when the blade body 121 is a planar shape, the plane where the blade body 121 is located is the reference plane A.

[0154] When the air treatment device 1 is in operation, an air guide channel is formed between the blade bodies 121 of adjacent air guide blades 120, and the airflow at the air outlet 11 is blown to the outside along the air guide channel. Since one side of the blade body 121 is a first curved portion 1213, the first curved portion 1213 can cause the airflow passing through the air guide channel to produce a Coanda effect, thereby changing the direction of the airflow. In turn, the air supply direction of the adjustment component 100 is changed, and the air supply area of ​​the air guide component 20 is adjusted.

[0155] The so-called Coanda effect, also known as the wall adhesion or Coanda effect, is a phenomenon in fluid mechanics. Specifically, the fluid (water flow or air flow) will deviate from the original flow direction during the flow process and flow along the protruding surface of the object. When there is surface friction (or fluid viscosity) between the fluid and the surface of the object it flows through, as long as the curvature is not large, the fluid will flow along the surface of the object.

[0156] Thus, when the airflow in the air duct flows toward the air outlet 11, it flows through the surface of the first curved portion 1213, and the airflow rubs against the surface of the first curved portion 1213. The flow direction of the airflow can be changed so that the airflow flows along the surface of the first curved portion 1213. Finally, when the airflow passes through the blade body 121 and is blown to the outside, it can flow along the extension direction of the first wind guide side 1211. In other words, the extension direction of the first wind guide side 1211 can be considered as the air supply direction of the wind guide blade 120.

[0157] In this way, the direction of the airflow blown out of the air outlet 11 is guided by the first air guide side 1211, so that the airflow flows along the extension direction of the first air guide side 1211. There is a first angle between the extension line of the first air guide side 1211 and the reference plane A where the blade body 121 is located, which is equivalent to changing the direction of the airflow that would originally flow along the extension direction of the reference plane A. Furthermore, the air supply angle of the adjustment component 100 can be changed, so that the air guide component 20 can adjust the air supply area more flexibly, and the air supply coverage area of ​​the air treatment device 1 is further expanded.

[0158] When the air treatment device 1 is in operation, the first curved portion 1213 in the blade body 121 can be close to the outside of the air outlet 11, and the first wind guide side 1211 is a side of the airflow out of the air guide channel. In this way, the airflow flows along the surface of the first curved portion 1213, and when the airflow is blown to the outside, it can flow along the extension direction of the first wind guide side 1211, thereby changing the air supply direction of the adjustment component 100.

[0159] Furthermore, in order to expand the air supply area of ​​the adjustment assembly 100, when the first air guide side 1211 faces the outside of the air outlet 11, the first curved portion 1213 can make the first air guide side 1211 deflect toward the same side of the air outlet 11. Figure 7 As shown, taking the air guide blade 120 in a vertical state as a reference, when the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guide side 1211 can extend to the same side of the air outlet 11. Taking the position of the air guide blade 120 closer to the left side of the length direction of the air outlet 11 as an example, the first air guide side 1211 can be tilted to the left side of the air outlet 11, and when the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guide side 1211 can extend to the left side of the air outlet 11.

[0160] In order to make the adjustment component 100 have a larger air supply coverage area, the air guide blade 120 is usually made to guide the air to the same side of the air outlet 11. For example, the air guide blade 120 close to the left side of the length direction of the air outlet 11 guides the air to the left side of the air outlet 11, and the air guide blade 120 close to the right side of the length direction of the air outlet 11 guides the air to the right side of the air outlet 11. By making the extension line of the first air guide side 1211 extend to the same side of the air outlet 11, when the first air guide side 1211 faces outside the air outlet 11, when the air guide blade 120 guides the air to the same side of the air outlet 11, the first air guide side 1211 can further increase the air supply deflection angle of the air guide blade 120. In turn, the air supply area of ​​the adjustment component 100 is expanded.

[0161] The aforementioned air guide blades guiding air to the same side of the air outlet are explained with the following two examples: for the air guide blade 120 close to the left side of the length direction of the air outlet 11, when the air guide blade 120 guides air to the left side of the air outlet 11, the first air guide side 1211 can further deflect the air supply angle of the air guide blade 120 to the left side of the air outlet 11. For the air guide blade 120 close to the right side of the length direction of the air outlet 11, when the air guide blade 120 guides air to the right side of the air outlet 11, the first air guide side 1211 can further deflect the air supply angle of the air guide blade 120 to the right side of the air outlet 11. Thus, the air supply deflection angle of the air guide assembly 20 to the left and right sides of the air outlet 11 is increased, and the air supply area and air supply coverage area of ​​the air guide assembly 20 are expanded.

[0162] Of course, in some embodiments, when the air treatment device 1 is in working state, the first curved portion 1213 in the blade body 121 may also face the inner side of the air outlet 11, and the first wind guide side 1211 is the side where the airflow flows into the wind guide channel. In this way, the flow direction of the airflow can be changed when the airflow flows into the wind guide channel. After the airflow flows along the surface of the first curved portion 1213 in the wind guide channel, the flow direction of the airflow is changed. Furthermore, the flow direction of the airflow after flowing out of the wind guide blade 120 is also changed, thereby changing the air supply direction of the adjustment component 100.

[0163] At this time, in order to expand the air supply area of ​​the regulating component 100, the first curved portion 1213 can also make the first air guide side 1211 deflected to the same side of the air outlet 11. When the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guide side 1211 can extend to the same side of the air outlet 11. In this way, when the air guide blade 120 needs to guide the air to the same side of the air outlet 11, the extension line of the first air guide side 1211 of the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, or the extension line of the first air guide side 1211 of the air guide blade 120 is deflected to the other side of the air outlet 11, so as to ensure that when the airflow flows outward from the air outlet 11, it is biased to flow to the same side of the air outlet 11 as a whole.

[0164] Taking the wind guide blade 120 near the left side of the air outlet 11 in the length direction as an example, when the wind guide blade 120 guides air to the left side of the air outlet 11, the extension line of the first wind guide side 1211 of the wind guide blade 120 facing the air outlet 11 can be perpendicular to the plane where the air outlet 11 is located, or the extension line of the first wind guide side 1211 of the wind guide blade 120 extends to the inside of the air outlet 11 and deflects to the right side of the air outlet 11. In this way, the wind guide blade 120 is deflected to the left side of the air outlet 11 as a whole, and can guide air to the left side of the air outlet 11.

[0165] In this way, with the center line of the length direction of the air outlet 11 as the boundary, when the air treatment device 1 is working, the air guide blade 120 located on the left side of the air outlet 11 can be deflected to the left (for example, the air guide blade 120 in the adjustment component 100 located on the left side of the two adjustment components 100 is deflected to the left), and the air supply angle and air supply area to the left side of the air outlet 11 are expanded through the air guiding effect of the first curved portion 1213. At the same time, the air guide blade 120 located on the right side of the air outlet 11 can be deflected to the right (for example, the air guide blade 120 in the adjustment component 100 located on the right side of the two adjustment components 100 is deflected to the right), and the air supply angle and air supply area to the right side of the air outlet 11 are expanded through the air guiding effect of the first curved portion 1213. Thereby, the air supply coverage area of ​​the air treatment device 1 is significantly expanded.

[0166] Alternatively, the air guide blades 120 located on both sides of the air outlet 11 can all be deflected to the left (for example, the air guide blades 120 in the two adjustment components 100 are all deflected to the left). At this time, the angle of deflection of all the air guide blades 120 on the left side of the air outlet to the left side of the air outlet is increased. In addition, the bearing plate 110 in the adjustment component 100 on the right side can also be deflected to the left, driving the angle of deflection of the air guide blades 120 thereon to the left to increase. Even, the bearing plate 110 in the adjustment component 100 on the left side can also be deflected to the left, driving the angle of deflection of the air guide blades 120 thereon to the left to increase. Therefore, the angle of air guiding to the left side of the air treatment device 1 has a significant gain.

[0167] Similarly, the air guide blades 120 located on both sides of the air outlet 11 can be deflected to the right (for example, the air guide blades 120 in the two adjustment components 100 are all deflected to the right). At this time, the angle at which all the air guide blades 120 on the right side of the air outlet are deflected to the right side of the air outlet is increased. In addition, the bearing plate 110 in the adjustment component 100 on the left side can be deflected to the right, driving the angle at which the air guide blades 120 thereon are deflected to the right to increase. Even, the bearing plate 110 in the adjustment component 100 on the right side can be deflected to the right, driving the angle at which the air guide blades 120 thereon are deflected to the right to increase. Therefore, the angle at which the air treatment device 1 guides the air to the right has a significant gain.

[0168] The following description takes the case where the air handling device 1 is in operation and the first curved portion 1213 of the blade body 121 of the air guide blade 120 faces the outside of the air outlet 11 and the first air guide side 1211 is inclined to the same side of the air outlet 11 as an example.

[0169] Specifically, take an air guide blade 120 on the left side near the length direction of the air outlet 11 as an example, if the first angle α between the extension line of the first air guide side 1211 of the air guide blade 120 and its reference plane A is 30°. When the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the angle between the extension line of the first air guide side 1211 and the vertical line of the air outlet 11 (the line perpendicular to the plane where the air outlet 11 is located) is 30°, which can achieve the air supply angle of the air guide blade 120 to deflect 30° to the left. When the air guide blade 120 deflects 15° to the left, the angle between the extension line of the first air guide side 1211 and the vertical line of the air outlet 11 is 45°, which can achieve the air supply angle of the air guide blade 120 to deflect 45° to the left.

[0170] In this way, when the air guide blade 120 guides air to the same side of the air outlet 11, the blade body 121 of the air guide blade 120 deflects a certain angle to the same side of the air outlet 11, and the angle between the first air guide side 1211 of the blade body 121 and the reference plane A is added, so that the first air guide side 1211 deflects a larger angle to the same side of the air outlet 11. The air supply angle of the blade body 121 is increased, the air supply area of ​​the adjustment component 100 is larger, and the air supply coverage area is wider.

[0171] At the same time, on the basis of a certain air supply angle of the air guide blade 120, the deflection angle of the blade body 121 is the required air supply angle minus the first angle α between the first air guide side 1211 of the blade body 121 and the reference plane A, and the required deflection angle of the blade body 121 is smaller. In this way, the driving motor 201 drives the blade body 121 to rotate at a smaller angle, and the energy consumption of the driving motor 201 is less, which is conducive to saving the energy consumption of the adjustment component 100 and reducing the overall energy consumption of the air treatment device 1.

[0172] Continue to refer to Figure 7 In some embodiments, on the basis of designing one side of the blade body 121 as the first curved portion 1213, the other side of the blade body 121 can also be designed as the second curved portion 1214. In other words, both sides of the central axis of the blade body 121 are designed as curved portions. Among them, the side of the second curved portion 1214 away from the central axis of the blade body 121 is the second wind-guiding side 1212 of the blade body 121. The extension direction of the second wind-guiding side 1212 also deviates from the reference plane A, and the extension line of the second wind-guiding side 1212 and the reference plane A have a second angle β.

[0173] In this way, when the blade body 121 rotates to the outside of the second curved portion 1214 close to the air outlet 11 and the second air guide side 1212 faces the outside of the air outlet 11, the airflow in the air guide channel flows along the surface of the second curved portion 1214. When the airflow is blown to the outside, it can flow along the extension direction of the second air guide side 1212, thereby changing the air supply direction of the adjusting component 100.

[0174] Figure 8 for Figure 6 A partial enlarged view of the wind guide blade at A in another vertical state. Figure 8 As shown, similar to the first curved portion 1213 , when the second wind guiding side 1212 faces outside the air outlet 11 , the second curved portion 1214 can make the second wind guiding side 1212 deflect toward the same side of the air outlet 11 . Figure 8In the figure, the wind guide blade 120 is in the reverse vertical state as a reference. When the wind guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the second wind guide side 1212 can extend to the same side of the air outlet 11. Taking the position of the wind guide blade 120 closer to the left side of the length direction of the air outlet 11 as an example, the second wind guide side 1212 can be tilted to the left side of the air outlet 11. When the wind guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the second wind guide side 1212 can extend to the left side of the air outlet 11.

[0175] Thus, when the second air guiding side 1212 faces the outside of the air outlet 11 and the air guiding blade 120 guides air to the same side of the air outlet 11 , the second air guiding side 1212 can further increase the air supply deflection angle of the air guiding blade 120 , thereby expanding the air supply area of ​​the regulating assembly 100 .

[0176] At the same time, on the basis of the air supply angle of the air guide blade 120 being constant, the deflection angle of the blade body 121 is the required air supply angle minus the second angle β between the second air guide side 1212 of the blade body 121 and the reference plane A, and the required deflection angle of the blade body 121 is smaller. Furthermore, the driving motor 201 drives the blade body 121 to rotate at a smaller angle, and the energy consumption of the driving motor 201 is smaller, which is conducive to saving the energy consumption of the adjustment component 100. No further details are given here.

[0177] like Figure 7 As shown, with the air guide blade 120 perpendicular to the plane where the air outlet 11 is located as a reference, when the first air guide side 1211 faces the outside of the air outlet 11, the extension line of the first air guide side 1211 extends to the same side of the air outlet 11. At this time, the second air guide side 1212 faces the inside of the air outlet 11, and the extension line of the second air guide side 1212 extends to the opposite side of the air outlet 11. Taking the left side of the air guide blade 120 close to the air outlet 11 as an example, the extension line of the first air guide side 1211 facing the outside of the air outlet 11 can extend to the left side of the air outlet 11, and the extension line of the second air guide side 1212 facing the inside of the air outlet 11 can extend to the right side of the air outlet 11.

[0178] like Figure 8 As shown, when the second wind guiding side 1212 faces the outside of the air outlet 11, the extension line of the second wind guiding side 1212 extends to the same side of the air outlet 11. At this time, the first wind guiding side 1211 faces the inside of the air outlet 11, and the extension line of the first wind guiding side 1211 extends to the opposite side of the air outlet 11. Taking the left side of the air guide blade 120 close to the air outlet 11 as an example, the extension line of the second wind guiding side 1212 facing the outside of the air outlet 11 can extend to the left side of the air outlet 11, and the extension line of the first wind guiding side 1211 facing the inside of the air outlet 11 can extend to the right side of the air outlet 11.

[0179] When the air treatment device 1 is working, the air guide blade 120 can be placed in a first open state. At this time, the first air guide side 1211 of the air guide blade 120 faces the outside of the air outlet 11, and the second air guide side 1212 of the air guide blade 120 faces the inside of the air outlet 11. Alternatively, the air guide blade 120 can also be placed in a second open state. At this time, the second air guide side 1212 of the air guide blade 120 faces the outside of the air outlet 11, and the first air guide side 1211 of the air guide blade 120 faces the inside of the air outlet 11.

[0180] In this way, the air guide blade 120 can increase the air supply deflection angle by using the first air guide side 1211, and can also increase the air supply deflection angle by using the second air guide side 1212. In this way, there is no limit on the rotation angle of the air guide blade 120, and the control of the air guide blade 120 is more flexible and the control method is simpler.

[0181] Fig. 9 for Figure 6 A partial enlarged view of the wind guide blade at A in the middle. Fig. 9 As shown, in some embodiments, the bending degree of the first curved portion 1213 may be greater than the bending degree of the second curved portion 1214. Furthermore, compared with the first angle α between the extension line of the first wind-guiding side 1211 and the reference plane A and the second angle β between the extension line of the second wind-guiding side 1212 and the reference plane A, the first angle α is greater than the second angle β.

[0182] With such a configuration, when the air guide blade 120 is in the first open state and the first air guide side 1211 of the air guide blade 120 faces the outside of the air outlet 11, the airflow flowing out of the air guide channel is deflected at a relatively larger angle to the same side of the air outlet 11. When the air guide blade 120 is in the second open state and the second air guide side 1212 of the air guide blade 120 faces the outside of the air outlet 11, the airflow flowing out of the air guide channel is deflected at a relatively smaller angle to the same side of the air outlet 11.

[0183] Thus, the user can adjust the opening state of the air guide blade 120 according to actual needs, so that the first air guide side 1211 of the air guide blade 120 faces outward or the second air guide side 1212 of the air guide blade 120 faces outward, so as to obtain different air supply directions and air supply areas. The adjustment component 100 can more flexibly adjust the air supply coverage range, which can improve the user experience of the air treatment device 1.

[0184] Furthermore, since the bending degrees of the first curved portion 1213 and the second curved portion 1214 are inconsistent, the deflection degree of the first wind-guiding side 1211 is greater than the deflection degree of the second wind-guiding side 1212. The structures on both sides of the central axis of the wind-guiding blade 120 are different, which facilitates the identification and installation of the wind-guiding blade 120. When assembling the adjustment component 100, the first wind-guiding side 1211 of each wind-guiding blade 120 can be made to face one side of the carrier plate 110, and the second wind-guiding side 1212 of each wind-guiding blade 120 can be made to face the other side of the carrier plate 110, so as to ensure that the adjustment component 100 is assembled correctly and reduce the probability of assembly rework and scrapping of the adjustment component 100.

[0185] In particular, when the first curved portion 1213 is close to the outside of the air outlet 11 and the first wind guide side 1211 is facing the outside of the air outlet 11, due to the large curvature of the first curved portion 1213 and the large deflection angle of the first wind guide side 1211, when the airflow flows along the first curved portion 1213 to the first wind guide side 1211 to deliver air outward, the Coanda effect can be better utilized to expand the air outlet angle of the air guide blade 120. At the same time, when the second curved portion 1214 is close to the inside of the air outlet 11 and the second wind guide side 1212 is facing the inside of the air outlet 11, due to the small curvature of the second curved portion 1214 and the large deflection angle of the second wind guide side 1212, it is more conducive to reducing the wind resistance in the air guide channel, increasing the gas flow rate in the air guide channel, and improving the air guide efficiency of the air guide blade 120.

[0186] Exemplarily, the difference between the first angle α and the second angle β can be between 6° and 12°. On the one hand, there is a significant angle difference between the first angle α and the second angle β. When the air guide blade is at the same deflection angle, when the first air guide side 1211 faces the outside of the air outlet 11 and the second air guide side 1212 faces the outside of the air outlet, the air supply direction and air supply area of ​​the adjustment component 100 are significantly different. On the other hand, the angle difference between the first angle α and the second angle β will not be too large, the overall smoothness of the air guide blade 120 is good, there is no excessive bending, and no stress concentration phenomenon will occur, which can ensure the overall reliability and service life of the air guide blade 120.

[0187] Exemplarily, the difference between the first angle α and the second angle β is 6.5°, 7.0°, 7.5°, 8.0°, 8.5°, 9.0°, 9.5°, 10.0°, 10.5°, 11.0°, 11.5°.

[0188] In other embodiments, the curved shape of the second curved portion 1214 can be completely consistent with the curved shape of the first curved portion 1213, and the blade body 121 of the wind guide blade 120 is a central symmetrical structure. When the rotation axis 122 of the wind guide blade 120 is located on the central axis of the blade body 121, the wind guide blade 120 as a whole is a central symmetrical structure. At this time, the first angle α between the extension line of the first wind guide side 1211 and the reference plane A is compared with the second angle β between the extension line of the second wind guide side 1212 and the reference plane A. The angle of the first angle α is equal to the angle of the second angle β.

[0189] In this way, whether the first air guide side 1211 is located outside the air outlet 11 or the second air guide side 1212 is located outside the air outlet 11, when the blade body 121 is deflected to a certain angle, the air supply deflection angle of the air guide blade 120 is the same, so that the air guide blade 120 has the same air supply adjustment effect. In addition, the air guide blade 120 has good structural symmetry, balanced force, better stability and higher reliability. In addition, because the air guide blade 120 is a symmetrical structure, the operability of the air guide blade 120 is better during installation, and there is no need to distinguish and position the two sides of the air guide blade 120. The installation efficiency of the air guide blade 120 is higher, and the appearance effect of the adjustment component 100 is also better.

[0190] In addition, refer to Figure 7 or Figure 8 In some embodiments, the blade body 121 further has a straight portion 1218, and the straight portion 1218 is located between the first curved portion 1213 and the second curved portion 1214, and two ends of the straight portion 1218 are respectively connected to the first curved portion 1213 and the second curved portion 1214.

[0191] In this way, the blade body 121 can guide the air through the first curved portion 1213 and the second curved portion 1214 on both sides to expand the air supply coverage of the air guide blade 120. At the same time, the straight portion 1218 in the middle part of the blade body 121 has better smoothness, which can reduce the wind resistance in the air guide channel and increase the gas flow rate out of the air outlet 11. In addition, the straight portion 1218 has a better dispersion effect on the air pressure, which can make the stress of the blade body 121 more uniform, and improve the reliability and service life of the blade body 121.

[0192] Taking the end of the straight portion 1218 connected to the first curved portion 1213 as its first end and the end of the straight portion 1218 connected to the second curved portion 1214 as its second end as an example, the first end of the straight portion 1218 can extend along the tangent direction of the first curved portion 1213, and the second end of the straight portion 1218 can extend along the tangent direction of the second curved portion 1214. In this way, the straight portion 1218 and the first curved portion 1213, and the straight portion 1218 and the second curved portion 1214 are all linear transitions, the blade body 121 has better overall smoothness, less wind resistance, and more uniform stress.

[0193] In other embodiments, only one side of the blade body 121 may be designed as the first curved portion 1213, and the other side of the blade body 121 may be designed as a straight portion. For example, the extension direction of the straight portion may be designed according to the reference plane A of the blade body 121, the straight portion may extend along the extension direction of the reference plane A, and the center plane of the straight portion in the thickness direction may be located within the reference plane A.

[0194] When one side of the blade body 121 is the first curved portion 1213 and the other side is the straight portion, when the wind guide blade 120 is installed, the first wind guide side 1211 of the wind guide blade 120 can be directed toward the outside of the air outlet 11. In addition, the rotation angle range of the wind guide blade 120 can be controlled so that the first curved portion 1213 of the blade body 121 is always located outside the air outlet 11, and the straight portion of the blade body 121 is always located inside the air outlet 11. The first wind guide side 1211 is used to guide the outlet airflow, and the air supply angle of the wind guide blade 120 is changed.

[0195] Of course, as mentioned above, the straight portion of the blade body 121 can also be located outside the air outlet 11, while the first curved portion 1213 of the blade body 121 is located inside the air outlet 11, and the direction of the airflow entering the air guide channel can be adjusted by using the first curved portion 1213. Thus, the air supply angle of the air guide blade 120 is changed. This will not be described in detail here.

[0196] As for the structural design of all the air guide blades 120 in the entire adjustment component 100, all the air guide blades 120 may be designed to be curved. In this way, the first air guide sides 1211 of all the air guide blades 120 may increase the air supply deflection angle of the air guide blades 120. The air supply angle of the entire adjustment component 100 may be changed, so that the deflection angle of the air supply area of ​​the entire adjustment component 100 is increased.

[0197] Alternatively, part of the air guide blades 120 may be designed to be curved, while the rest of the air guide blades 120 may remain flat. The curved air guide blades 120 may increase the air supply deflection angle of the corresponding area of ​​the adjustment component 100. The rest of the flat air guide blades 120 may maintain the original air supply deflection angle of the corresponding area of ​​the adjustment component 100.

[0198] At this time, the air guide blade 120 closer to the end of the air outlet 11 can be designed as a curved surface, while the air guide blade 120 closer to the center of the air outlet 11 can be designed as a flat surface. The air supply deflection angle of the air guide blade 120 closer to the center of the air outlet 11 is smaller, and the air supply deflection angle of the air guide blade 120 closer to the end of the air outlet 11 is larger. From the center of the air outlet 11 to the end of the air outlet 11, the air supply deflection angle of the adjustment component 100 increases. In this way, the air supply area of ​​the adjustment component 100 is larger, the air supply coverage is wider, and the air output is softer.

[0199] In the adjustment component 100, whether only some of the air guide blades 120 are designed as curved surfaces or all of the air guide blades 120 are designed as curved surfaces, all the air guide blades 120 with curved surfaces can maintain a consistent shape. In this way, the air guide blades 120 with curved surfaces have a consistent air supply adjustment effect on the corresponding area of ​​the adjustment component 100.

[0200] Alternatively, in the direction close to the end of the air outlet 11, that is, from the center of the air outlet 11 to the end of the air outlet 11, the curvature of each air guide blade 120 in a curved shape may gradually increase. For example, the first angle α between the extension line of the first air guide side 1211 of each air guide blade 120 and the reference plane A may gradually increase. The second angle β between the extension line of the second air guide side 1212 of each air guide blade 120 and the reference plane A may also gradually increase.

[0201] In this way, the air supply deflection angle of the adjustment component 100 gradually increases from the center of the air outlet 11 to the end of the air outlet 11, and the air supply area of ​​the adjustment component 100 is larger and the air supply coverage is wider. In addition, the air supply area gradually expands outward, the air volume is more dispersed, and the air supply is softer.

[0202] See also Figure 6, taking the air guide component 20 having two adjustment components 100 as an example, when the air treatment device 1 is working, in the adjustment component 100 located on the left side of the length direction of the air outlet 11, the first air guide side 1211 of the air guide blade 120 in a curved shape is tilted toward the left side of the air outlet 11. In the adjustment component 100 located on the right side of the length direction of the air outlet 11, the first air guide side 1211 of the air guide blade 120 in a curved shape is tilted toward the right side of the air outlet 11. The air supply area of ​​the air guide component 20 can be expanded to the left and right sides, which can increase the air supply coverage of the air guide component 20. The bearing plates 110 of the two additional adjustment components 100 swing outward relative to each other, which can further expand the air supply coverage of the air guide component 20.

[0203] The curved air guide blade 120 will be described in detail below.

[0204] The first angle α between the extension line of the first wind-guiding side 1211 of the wind-guiding blade 120 and the reference plane A may be in the range of 5° to 55°. Figure 7 As shown, the first wind guide side 1211 is taken as an example facing the outside of the air outlet 11, and the plane direction of the wind guide blade 120 perpendicular to the air outlet 11 is taken as a reference. When the first angle α between the extension line of the first wind guide side 1211 and the reference plane A is 5°, the air supply direction of the wind guide blade 120 is deflected 5° to the same side of the air outlet 11; the wind guide blade 120 continues to deflect 85° to the same side of the air outlet 11, so that the extension line of the first wind guide side 1211 is parallel to the plane direction of the air outlet 11. When the first angle α between the extension line of the first wind guide side 1211 and the reference plane A is 55°, the air supply direction of the wind guide blade 120 is deflected 55° to the same side of the air outlet 11; the wind guide blade 120 continues to deflect 35° to the same side of the air outlet 11, so that the extension line of the first wind guide side 1211 is parallel to the plane direction of the air outlet 11.

[0205] In this way, when the air guide blade 120 guides the air through the first air guide side 1211, the air guide blade 120 only needs to rotate within a small angle range, so that the air guide blade 120 can have an air supply area with a large angle range. The air guide blade 120 can flexibly adjust the air supply angle to change the air supply area of ​​the adjustment component 100. In addition, the first angle α between the extension line of the first air guide side 1211 and the reference plane A is not too large, the bending degree of the first curved portion 1213 is appropriate, and the air guide blade 120 will not hinder the flow of airflow. The overall wind resistance of the adjustment component 100 is very small and will not affect the air supply volume of the air treatment device 1.

[0206] Exemplarily, the first angle α between the extension line of the first wind-guiding side 1211 and its reference plane A can be between 25° and 55°. By making the first angle α between the extension line of the first wind-guiding side 1211 and its reference plane A greater than or equal to 25°, when the wind-guiding blade 120 is perpendicular to the plane direction of the air outlet 11, the deflection angle of the air supply direction of the wind-guiding blade 120 toward the same side of the air outlet 11 is greater than or equal to 25°. The first wind-guiding side 1211 can significantly increase the air supply deflection angle of the wind-guiding blade 120, and can better expand the air supply area of ​​the adjustment component 100.

[0207] For example, the first angle α between the extension line of the first wind guiding side 1211 and its reference plane A may be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0208] Continue to refer to Figure 7 The first curved portion 1213 of the blade body 121 can be a smooth curved portion, and the overall curved shape of the first curved portion 1213 is relatively gentle. The first curved portion 1213 can allow the airflow to flow smoothly along its surface, and will not hinder the flow of the airflow while changing the flow direction of the airflow. The airflow flows out of the air guide channel smoothly along the first curved portion 1213, so that the air treatment device 1 stably blows the airflow to the outside.

[0209] Furthermore, the first curved portion 1213 may have only one curved vertex 12131. That is, the first curved portion 1213 is bent only once toward one side in the thickness direction of the blade body 121. In order to achieve the first wind-guiding side 1211 being deflected toward the same side of the air outlet 11, the first curved portion 1213 may be slightly convex toward the other side of the air outlet 11. In this way, the first curved portion 1213 is prevented from forming a continuously concave and convex wave surface, so as to prevent the first curved portion 1213 from changing the flow direction of the airflow multiple times, so as to prevent the air supply direction of the air guide blade 120 from being affected, and to ensure the adjustment effect of the first curved portion 1213 on the air supply deflection angle of the air guide blade 120. It is also possible to prevent the airflow from being turbulent when flowing through the first curved portion 1213, so as to ensure that the airflow can flow out of the air guide blade 120 smoothly and orderly, so as to avoid the loss of the air supply volume of the air treatment device 1.

[0210] When the first curved portion 1213 has only one bending vertex 12131, the extension line of the first wind-guiding side 1211 extends to one side of the reference plane A, and the bending vertex 12131 can be located on the other side of the reference plane A. Taking the wind-guiding blade 120 close to the left side of the length direction of the air outlet 11 as an example, specifically taking the plane where the wind-guiding blade 120 is perpendicular to the air outlet 11 as a reference reference, the extension direction of the first wind-guiding side 1211 of the wind-guiding blade 120 can extend to the left side of the reference plane A, and the bending vertex 12131 can be located on the right side of the reference plane A.

[0211] In this way, it is avoided that the extension line of the first wind-guiding side 1211 and the bending vertex 12131 of the first curved portion 1213 are located on the same side of the reference plane A, and it is avoided that the first curved portion 1213 is excessively bent toward one side of the wind-guiding blade 120. The wind-guiding blade 120 is flat as a whole, with a small degree of bending, and the wind resistance generated is small. During the long-term use of the wind-guiding blade 120, the wind-guiding blade 120 is less compressed by the airflow, and the reliability of the wind-guiding blade 120 is higher and the service life is longer. Moreover, the wind-guiding blade 120 is still flat as a whole, and occupies a small space, which is convenient for the arrangement of the wind-guiding blade 120 on the carrier plate 110.

[0212] Exemplarily, the center line of the first wind-guiding side 1211 in the thickness direction may be located on the reference plane A. In this way, the bending shape of the first curved portion 1213 is constrained, and the first curved portion 1213 is limited to a smaller bending amplitude, the blade body 121 has a higher smoothness, and has less obstruction to the fluid, which is more in line with the efficient air supply requirements of the air treatment device 1.

[0213] When the other side of the blade body 121 is set as the second curved portion 1214, the angle range of the second angle β between the extension line of the second wind-guiding side 1212 of the wind-guiding blade 120 and the reference plane A can be 5°-45°. Figure 8 As shown, the second air guide side 1212 is facing the outside of the air outlet 11 as an example, and the plane direction of the air guide blade 120 perpendicular to the air outlet 11 is used as a reference. When the second angle β between the extension line of the second air guide side 1212 and the reference plane A is 5°, the air supply direction of the air guide blade 120 is deflected 5° to the same side of the air outlet 11; the air guide blade 120 continues to deflect 85° to the same side of the air outlet 11, so that the extension line of the second air guide side 1212 is parallel to the plane direction of the air outlet 11. When the second angle β between the extension line of the second air guide side 1212 and the reference plane A is 45°, the air supply direction of the air guide blade 120 is deflected 45° to the same side of the air outlet 11; the air guide blade 120 continues to deflect 45° to the same side of the air outlet 11, so that the extension line of the second air guide side 1212 is parallel to the plane direction of the air outlet 11.

[0214] In this way, when the air guide blade 120 guides the air through the first air guide side 1211, the air guide blade 120 only needs to rotate within a small angle range, so that the air guide blade 120 can have an air supply area with a large angle range. In addition, the second angle β between the extension line of the second air guide side 1212 and the reference plane A is not too large, the bending degree of the second curved portion 1214 is appropriate, and the air guide blade 120 does not hinder the flow of air. No further details are given here.

[0215] Exemplarily, the second angle β between the extension line of the second wind-guiding side 1212 and its reference plane A can be between 25° and 45°. In this way, the second wind-guiding side 1212 can significantly increase the air supply deflection angle of the wind-guiding blade 120, and can better expand the air supply area of ​​the adjustment component 100. For example, the second angle β between the extension line of the second wind-guiding side 1212 and its reference plane A can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0216] On this basis, similar to the first curved portion 1213, the second curved portion 1214 may also be a smooth curved portion. In addition, the second curved portion 1214 may also have only one curved vertex 12141. For example, the extension line of the second wind-guiding side 1212 extends to one side of the reference plane A, and the curved vertex 12141 may be located on the other side of the reference plane A. In addition, the center line of the second wind-guiding side 1212 in the thickness direction may be located on the reference plane A. This will not be repeated here.

[0217] When the other side of the blade body 121 is set as a straight portion, the center line of the second wind-guiding side 1212 of the blade body 121 in the thickness direction can also be located on the reference plane A. In this way, both sides of the guide vane body 121 are located on its reference plane A, and the overall design of the blade body 121 is more inclined to a planar form, with a more regular shape, good wind-guiding effect, good stability, and high reliability.

[0218] Fig.10 A three-dimensional structural diagram of another air guide assembly provided in an embodiment of the present application. Fig.11 for Fig.10 A partial enlarged view of the air guide assembly in FIG. Fig.11 The structure of the part where one of the air guide blades 120 of the adjustment component 100 is located is schematically shown.

[0219] Reference Fig.10 and Fig.11 As shown, a plurality of air outlet holes 1215 may be distributed on the blade body 121 of the air guide blade 120, and the air outlet holes 1215 penetrate the two side surfaces of the blade body 121 in the thickness direction. When the blade body 121 is the aforementioned curved surface shape, a plurality of air outlet holes 1215 may be opened on the blade body 121. When the blade body 121 is a flat surface shape, a plurality of air outlet holes 1215 may also be opened on the blade body 121. All blade bodies 121 of the adjustment assembly 100 may be opened with air outlet holes 1215.

[0220] By opening a plurality of air outlet holes 1215 on the blade body 121 , when the air treatment device 1 is in operation, the air flow blown out of the air duct can pass through the air outlet holes 1215 on the blade body 121 and flow outward.

[0221] Specifically, when the air guide blades 120 are in the open state, there is an angle between the air guide blades 120 and the plane where the air outlet 11 is located, and an air guide channel is formed between adjacent air guide blades 120. At this time, part of the airflow blown out of the air duct will flow outward along the air guide channel, and another part can flow outward through the air outlet holes 1215 on the blade body 121. In this way, the air supply effect of the air treatment device 1 is improved by using the air outlet holes 1215 on the blade body 121.

[0222] When the air handling device 1 supplies air to the outside through the regulating component 100, in addition to generating a first airflow flowing outward along the air guide channel, a second airflow flowing outward through the air outlet 1215 is also generated, and the flow direction of the second airflow is different from the flow direction of the first airflow. Under the counteraction of the second airflow to the first airflow, the flow rate of the first airflow can be slowed down, and strong wind can be avoided from being blown out from the air outlet 11, so that the air supply effect of the air handling device 1 can be softer, and the use comfort of the air handling device 1 can be improved.

[0223] It should be noted that the aperture of the air outlet hole 1215 provided on the blade body 121 is small, and the airflow in the air duct will still flow outward through the air guide channel between adjacent air guide blades 120 first. Therefore, most of the airflow in the air duct will flow out through the air guide channel between adjacent air guide blades 120, and only a small part of the airflow will flow out through the air outlet hole 1215. This small part of the airflow passing through the air outlet hole 1215 can play a good role in counteracting the mixed flow and can reduce the air flow rate. At the same time, it will not cause too much impact on the overall air supply direction and air supply area of ​​the adjustment component 100, and the air supply adjustment effect of the adjustment component 100 can be guaranteed.

[0224] When the air guide blades 120 are in the closed state, the air guide blades 120 are generally parallel to the plane where the air outlet 11 is located, and the air guide blades 120 of the adjustment component 100 can be located on the same straight line, and there is only a small installation gap between adjacent air guide blades 120. At this time, the air flow blown out of the air duct basically flows outward through the air outlet holes 1215 on the blade body 121. Since the aperture of the air outlet holes 1215 is small and the opening area of ​​the blade body 121 is limited, the flow rate of the air flow flowing out of the air outlet holes 1215 of each air guide blade 120 is small, and the air supply volume and wind speed of the air treatment device 1 are small.

[0225] For example, when the air handling device 1 is heating, the air guide blades 120 can be closed, and only the air outlet holes 1215 on each air guide blade 120 are used to transport hot air outward. Since the flow rate of hot air is low, the wind resistance of the blade body 121 to the hot air is small, and the hot air can be stably output outward through the air outlet holes 1215 on the blade body 121. In addition, only outputting hot air outward through the air outlet holes 1215 on the blade body 121 can limit the flow rate of hot air, maintain the indoor space at a suitable temperature, and reduce the energy consumption of the air handling device 1.

[0226] Among them, the plurality of air outlet holes 1215 can be evenly distributed on the surface of the blade body 121. In this way, it can be ensured that there is a sufficient opening area on the blade plate body, so that the second airflow flowing out through the air outlet holes 1215 has a sufficient air volume, ensuring that the second airflow can effectively play a role in reducing the flow rate of the first airflow, and realizing the softening of the air supply of the air treatment device 1. In addition, since the air outlet holes 1215 are evenly distributed in various areas of the blade body 121, the pressure effect of the second airflow on the blade body 121 is evenly distributed on the blade body 121, the force uniformity of the blade body 121 is good, and the reliability and service life of the blade body 121 can be improved.

[0227] Exemplarily, the air outlet holes 1215 may be distributed in an array on the surface of the blade body 121. Along the height direction of the blade body 121 (the height direction of the blade body 121 is, for example, the width direction of the air outlet holes 1215), multiple rows of air outlet holes 1215 are sequentially arranged, and each row of air outlet holes 1215 includes multiple air outlet holes 1215 sequentially arranged along the width direction of the blade body 121. Two adjacent rows of air outlet holes 1215 may be staggered, wherein each air outlet hole 1215 in one row may be correspondingly located between two adjacent air outlet holes 1215 in another row.

[0228] The area occupied by the air outlet 1215 on the blade body 121 can be 45%-85% of the total area of ​​the blade body 121, that is, the opening rate of the blade body 121 can be 45%-85%. In this way, the blade body 121 has a sufficient opening area to ensure the flow area of ​​the blade body 121 itself, and the airflow flowing out through the air outlet 1215 of the blade body 121 reaches a certain flow rate, which can play an effective air supply softening effect.

[0229] For example, the opening rate of the blade body 121 can be between 50% and 60%. In this way, more than half of the area of ​​the blade body 121 is occupied by the air outlet 1215, and the air flow rate of the air outlet 1215 of the blade body 121 is sufficient. In addition, the opening rate of the blade body 121 is avoided to be too large, and the hole processing requirements of the blade body 121 can be met, and the structural strength and reliability of the blade body 121 can be ensured.

[0230] Fig.12 This is a cross-sectional view of the wind guide blade provided in the embodiment of the present application. Fig.12 As shown in the figure, the air guide blade 120 is cut off in the middle area of ​​an outlet air hole 1215 along the width direction of the air guide blade 120. On the basis of opening the outlet air hole 1215 on the blade body 121, the embodiment further designs the extension direction of the outlet air hole 1215. The outlet air hole 1215 does not extend along the thickness direction of the blade body 121, but the extension direction of the outlet air hole 1215 is tilted.

[0231] For ease of explanation, in this embodiment, the two side surfaces of the blade body 121 in the thickness direction are defined as the first surface 1216 and the second surface 1217. The first surface 1216 is the side where the extension line of the first wind guide side 1211 is located. That is, when the wind guide blade 120 is in the open state and the wind guide blade 120 is tilted and deflected to the same side of the air outlet 11, the first surface 1216 of the blade body 121 faces the inner side of the air outlet 11, and the second surface 1217 of the blade body 121 faces the outer side of the air outlet 11 (see Figure 6 shown).

[0232] Taking the wind guide blade 120 near the left side of the length direction of the air outlet 11 as an example, when the wind guide blade 120 is in the open state and the wind guide blade 120 is tilted and deflected toward the left side of the air outlet 11, the air supply angle of the wind guide blade 120 is deflected toward the left side of the air outlet 11. At this time, the first wind guide side 1211 of the blade body 121 faces the outside of the air outlet 11, the second wind guide side 1212 of the blade body 121 faces the inside of the air outlet 11, and the first surface 1216 of the blade body 121 faces the inside of the air outlet 11, and the second surface 1217 of the blade body 121 faces the outside of the air outlet 11. The extension line of the first wind guide side 1211 extends toward the left side of the air outlet 11, that is, the extension line of the first wind guide side 1211 extends toward the side where the first surface 1216 is located.

[0233] In this embodiment, from the first surface 1216 of the blade body 121 to the second surface 1217 of the blade body 121, the air outlet hole 1215 may be inclined toward the side where the first wind-guiding side 1211 of the blade body 121 is located. In other words, the central axis of the air outlet hole 1215 extends obliquely toward the first wind-guiding side 1211, and the angle between the central axis of the air outlet hole 1215 and the reference plane A of the blade body 121 on the side where the first wind-guiding side 1211 is located is less than 90°, while the angle between the central axis of the air outlet hole 1215 and the reference plane A of the blade body 121 on the side where the second wind-guiding side 1212 is located is greater than 90°.

[0234] Thus, when the air guide blades 120 are in the open state, in the air supply direction of the adjustment component 100, the angle between the extension direction of the air outlet hole 1215 and the side of the blade body 121 close to the outside of the air outlet 11 is an acute angle, and the air outlet direction of the air outlet hole 1215 tends to the air guide direction of the blade body 121. The direction difference between the flow direction of the first airflow flowing outward along the air guide channel between adjacent air guide blades 120 and the flow direction of the second airflow flowing outward through the air outlet hole 1215 is less than 90°.

[0235] When the air guide blades 120 deflect toward the same side of the air outlet 11, and the first airflow flowing out of the air guide channel between the adjacent air guide blades 120 deflects toward the same side of the air outlet 11, although the second airflow flowing out of the air outlet hole 1215 of the blade body 121 does not obviously deflect toward the same side of the air outlet 11, the second airflow will not obviously deflect toward the other side of the air outlet 11. At the same time, the flow rate of the second airflow is obviously smaller than the flow rate of the first airflow. Therefore, the second airflow has a smaller impact on the overall air supply direction of the adjustment component 100, and the adjustment accuracy of the adjustment component 100 on the air supply direction and air supply area can be guaranteed.

[0236] Taking the air guide blade 120 close to the left side of the air outlet 11 as an example, when the air guide blade 120 is deflected to the left side of the air outlet 11, the first airflow flowing out from the air guide channel between adjacent air guide blades 120 is deflected toward the left side of the air outlet 11, and the direction of the second airflow flowing out from the air outlet 1215 of the blade body 121 itself can be roughly toward the front of the air outlet 11, or the direction of the second airflow can also be slightly deflected toward the left side of the air outlet 11.

[0237] Thus, from the first surface 1216 to the second surface 1217 of the blade body 121, by making the air outlet 1215 on the blade body 121 tilt toward the first air guide side 1211, the second airflow flowing out of the air outlet 1215 can offset the first airflow flowing out along the air guide channel, thereby making the air supply of the adjustment component 100 softer. At the same time, the interference of the second airflow on the overall air supply direction of the adjustment component 100 can also be reduced, thereby ensuring the air supply adjustment accuracy of the adjustment component 100.

[0238] Specifically, the angle between the extension direction of the air outlet 1215 on the blade body 121 and the reference plane A ranges from 30° to 60°.

[0239] Taking the deflection angle of the blade body 121 deflected to the same side of the air outlet 11 as 45° as a reference, the angle between the blade body 121 and the vertical direction of the air outlet 11 (the direction perpendicular to the plane where the air outlet 11 is located) is 45°, and the angle between the blade body 121 and the plane direction of the air outlet 11 is also 45°. At this time, the deflection degree of the blade body 121 is moderate, and the air supply angle of the adjustment component 100 is more obviously deflected to the same side of the air outlet 11. It is more appropriate to judge whether the air outlet direction of the air outlet 1215 is appropriate based on this deflection angle.

[0240] Taking the air guide blade 120 near the left side of the air outlet 11 as an example, when the angle between the extension direction of the air outlet 1215 and the reference plane A is 60°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the airflow blown out of the air outlet 1215 is deflected 15 degrees to the right side of the air outlet 1215. When the angle between the extension direction of the air outlet 1215 and the reference plane A is 30°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the airflow blown out of the air outlet 1215 is deflected 15 degrees to the left side of the air outlet 1215.

[0241] It can be seen that the smaller the angle between the extension direction of the air outlet 1215 and the reference plane A, the closer the air outlet direction of the air outlet 1215 is to the overall air supply direction of the adjustment component 100. In addition, when the deflection angle of the blade body 121 to the same side of the air outlet 11 is greater than 45°, it means that the adjustment component 100 has a more obvious effect of guiding the air to the same side of the air outlet 11. Therefore, by designing the angle between the extension direction of the air outlet 1215 and the reference plane A to be less than or equal to 60°, when the adjustment component 100 guides the air to the same side of the air outlet 11, the airflow blown out of the air outlet 1215 will not be obviously directed to the other side of the air outlet 11, and the overall adjustment effect of the adjustment component 100 is better.

[0242] Exemplarily, the angle between the extension direction of the air outlet 1215 on the blade body 121 and the reference plane A is in the range of 40°-50°. Continuing with the air guide blade 120 close to the left side of the air outlet 11 as an example, when the angle between the extension direction of the air outlet 1215 and the reference plane A is 50°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the second airflow blown out of the air outlet 1215 is deflected 5 degrees to the right side of the air outlet 1215. When the angle between the extension direction of the air outlet 1215 and the reference plane A is 30°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the second airflow blown out of the air outlet 1215 is deflected 15 degrees to the left side of the air outlet 1215.

[0243] In this way, when the air supply angle of the regulating component 100 is more obviously deflected to the same side of the air outlet 11, the second airflow blown out from the air outlet 1215 of the blade body 121 is roughly blown in front of the air outlet 11, or the second airflow blown out from the air outlet 1215 is also deflected to the same side of the air outlet 11. In this way, it can be avoided that the air outlet 1215 affects the overall air supply direction of the regulating component 100. In addition, the inclination of the air outlet 1215 is not too large, which is convenient for processing the air outlet 1215 on the blade body 121. In addition, the space occupied by the air outlet 1215 in the plane direction of the blade body 121 is moderate, and a sufficient number of air outlet holes 1215 can be processed on the blade body 121 to ensure the air supply volume of the air outlet 1215 of the blade body 121.

[0244] For example, the angle between the extension direction of the air outlet 1215 on the blade body 121 and the reference plane A is 45°. Continuing with the example of the wind guide blade 120 close to the left side of the air outlet 11, when the angle between the extension direction of the air outlet 1215 and the reference plane A is 45°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the angle between the second airflow blown out of the air outlet 1215 and the vertical direction of the air outlet 11 is 0°, and the second airflow blows directly in front of the air outlet 11. In this way, when the air supply angle of the adjustment component 100 is obviously deflected to the same side of the air outlet 11, the airflow blown out of the air outlet 1215 is also biased to the same side of the air outlet 11.

[0245] As for the shape of the air outlet 1215 on the blade body 121, this embodiment does not impose any specific restrictions on this. The air outlet 1215 can be in a relatively regular shape to avoid stress concentration. For example, the cross-sectional shape of the air outlet 1215 can be circular, elliptical, or regular polygonal. When the cross-sectional shape of the air outlet 1215 is a regular polygon, the cross-sectional shape of the air outlet 1215 is, for example, a regular pentagon, a regular hexagon, a regular octagon, etc.

[0246] According to the size of the blade body 121, an air outlet hole 1215 of a suitable size can be processed on the blade body 121. Taking the air outlet hole 1215 as a circular hole as an example, the aperture of the air outlet hole 1215 can be between 4mm and 9mm. In this way, the air outlet hole 1215 has a sufficient cross-sectional area, and the air outlet hole 1215 meets the air supply demand, ensuring that the air outlet hole 1215 on the blade body 121 has a certain air supply volume. In addition, the cross-sectional area of ​​the air outlet hole 1215 is not too large, and a sufficient number of air outlet holes 1215 can be opened on the blade body 121 to prevent the air outlet hole 1215 from affecting the structural strength and reliability of the blade body 121.

[0247] Exemplarily, the aperture of the air outlet hole 1215 may be 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm, 8.5 mm, etc.
