Description

Technical Field

[0001] The present invention belongs to the technical field of automobile air-conditioning systems, and in particular relates to an air outlet mechanism for converting mechanical wind into natural wind. Background Art

[0002] Currently, most air vents in automotive air conditioning systems utilize traditional designs, including single-channel structures and fixed wind direction adjustment mechanisms. These vents improve airflow quality by adjusting blade angles or adding diffusers. As consumers' demands for automotive comfort continue to rise, so too do the demands for airflow distribution, wind speed control, and intelligence within air conditioning vents. Consumers often expect the cabin's ventilation system to deliver a natural breeze experience, which inevitably requires the vent structure to convert the outflow into a natural breeze.

[0003] However, the air outlets in traditional automotive air conditioning systems have the following defects:

[0004] (1) Limited by the direct blowing effect, the traditional air outlet blows directly into the human body in a concentrated direction, which can easily cause physical discomfort such as dryness, uneven temperature, etc.

[0005] (2) The fixed wind direction and wind speed of traditional air outlet structures make it difficult to simulate the randomness and volatility of natural wind. For example, adjusting the angle of the airflow through blades and designing a diffusion network can only alleviate local problems but does not solve the problem of dynamic airflow distribution. It cannot produce airflow diffusion effects in the horizontal and vertical directions, and cannot obtain airflow with high turbulence effects. It cannot produce a changing airflow field.

[0006] (3) The single-channel structure design of the traditional air outlet structure has poor adjustment flexibility, which makes the air outlet subject to greater restrictions when adjusting the wind direction and wind speed, making it difficult to take into account the needs of different areas in the car.

[0007] (4) In the traditional air outlet structure, after the blades are connected together through a connecting rod, all the blades can only move synchronously; they cannot move differentially.

[0008] The purpose of the present invention is to reconstruct the overall structure of the air outlet in an automobile air conditioning system so that the blowing system can achieve a natural wind experience to the greatest extent possible. The decomposed objectives set by this application that need to be taken into account or focused on include:

[0009] (1) Changing the traditional single-channel structure: After the airflow is split through the dual channels, the outflow is re-coupled at the outlet to make the outflow softer.

[0010] (2) Relative independent movement of blades: Each blade arranged in the air duct has relatively independent movement and different movement postures, which can realize the airflow in the upper and lower channels and achieve different forms of mixing. The mixed airflow has the greatest degree of randomness, uncertainty and irregularity.

[0011] (3) Intelligent adaptation: Cooperate with the sensors of the intelligent cockpit to sense the temperature status of the passenger compartment and automatically adjust the air outlet mode, such as general mode, natural wind mode, swept wind mode, breeze mode, etc.

[0012] (4) Energy saving and noise reduction: The various air outlet modes mentioned in (3) above also have energy saving and noise reduction performance, reducing noise sources while reducing energy consumption and costs. Summary of the Invention

[0013] The technical problem to be solved by the present invention is to provide an air outlet mechanism that converts mechanical wind into natural wind to solve at least one problem mentioned in the background technology or achieve better technical effects.

[0014] In order to solve the above technical problems, the inventors have come up with the technical solution of the present invention through practice and summary. The present invention discloses an air outlet mechanism for converting mechanical wind into natural wind, comprising an outer shell, wherein the outer shell comprises an outer shell upper cover and an outer shell lower cover that are mutually connected, one end of the outer shell is an air inlet end, and the other end is an air outlet end;

[0015] An inner shell is installed in the outer shell, and the inner shell includes an inner shell upper cover and an inner shell lower cover that cooperate with each other, and the inner shell divides the inner space of the outer shell into an upper channel and a lower channel;

[0016] It also includes an air inlet control unit and an air outlet control unit: the air inlet control unit adjusts the air inlet volume entering the upper channel and the lower channel; the air outlet control unit adjusts the air outlet state of the upper channel and the lower channel.

[0017] The air inlet control unit of this solution can realize the switching and different proportions of the upper / lower channel airflow, and the air outlet control unit can realize the mixing of the air outlet directions of the upper and lower channels, adjust the direction and speed of the airflow, thereby achieving fine adjustment, which can better simulate the effect of natural wind and improve passenger comfort.

[0018] Compared with the single-channel design, the dual-channel structure of the upper and lower channels is more flexible in adjusting the wind direction and speed, and can systematically adapt to the needs of different areas in the warehouse. Through dynamic control, it can also achieve adaptation to different environments and distribute airflow on demand, further enhancing the passenger comfort experience. In this way, it effectively solves the problem of traditional air outlets blowing directly on the human body, which can easily cause dryness, uneven hot and cold, and other physical discomforts.

[0019] Preferably, the air inlet control unit includes a first driving element, which is installed outside the outer shell; the first driving element cooperates to drive a driving disc to perform reciprocating rotation around the axis, and one side of the driving disc includes a first driving chute and a second driving chute;

[0020] The air intake control unit further includes a first damper, a second damper, a first connecting rod, and a second connecting rod. The first damper and the second damper are rotatably connected to the inner housing. The first damper limit is located in the upper channel to control its opening and closing degree, and the second damper limit is located in the lower channel to control its opening and closing degree. The first damper rotates around a first axis, the end of the first axis is connected to the side surface of one end of the first connecting rod, and the other side surface of the other end of the first connecting rod extends out of a first cylinder. The second damper rotates around a second axis, the end of the second axis is connected to the side surface of one end of the second connecting rod, and the other side surface of the other end of the second connecting rod extends out of a second cylinder.

[0021] The first cylinder is matched with the first driving slot, and the second cylinder is matched with the second driving slot.

[0022] In this scheme, the movement trajectory of the first cylinder in the first driving chute and the movement trajectory of the second cylinder in the second driving chute can be designed according to functional needs, and the air intake volume of the upper channel / lower channel can be controlled and adjusted according to functional needs. For example: the initial state is that the first air door closes the upper channel and the second air door closes the lower channel; the first adjustment stage is: the first air door closes the upper channel, and the second air door gradually opens the lower channel until it is fully open; the second adjustment stage is that the first air door gradually opens the upper channel, and the second air door keeps the lower channel open. In this stage, the free end of the first air door swings up and down at the air inlet end to adjust the ratio of the air volume entering the upper channel and the lower channel. The limit of the second adjustment stage should not exceed the critical state, which is: the state where the first air door closes the lower channel.

[0023] Preferably, it includes a limiting element, the limiting element is mounted on the outside of the outer shell, the first driving element is mounted on the limiting element, the inner side of the limiting element includes a cylindrical groove, and the cylindrical groove is adapted to the outer contour of the driving disc;

[0024] The other side of the drive disc includes a boss, which includes a cylinder and a limiting protrusion extending from the side of the cylinder; an external gear extends from the end surface of the cylinder; the first drive element outputs rotational motion and cooperates with the external gear;

[0025] The outer side of the limiting element includes a groove, and the groove includes a cylindrical portion and a fan-shaped protruding portion;

[0026] The cylindrical body fits neatly within the cylindrical portion and rotates about its axis. The limiting protrusion is located within the sector-shaped extension and rotates about its axis. When the first driving element drives the external gear, the driving disc and boss rotate synchronously about their axis. The driving disc rotates about its axis within the confined space of the cylindrical groove, the cylindrical body rotates about its axis within the confined space of the cylindrical portion, and the limiting protrusion rotates about its axis within the sector-shaped extension.

[0027] When the first driving element drives the external gear to rotate, the driving disc and the boss rotate synchronously around the axis. The driving disc rotates around the axis in the space limited by the cylindrical groove, the cylinder rotates around the axis in the space limited by the cylindrical part, and the limiting protrusion rotates around the axis in the fan-shaped protruding part.

[0028] This solution has a protective effect: the movement path of the limiting protrusion is limited by the fan-shaped protruding part, the maximum angular range of the rotation of the drive disc is limited, the rotation range of the first drive slot and the second drive slot is limited, the movement trajectory of the first cylinder in the first drive slot is limited and derailment failure or collision damage to parts is prevented, and the movement trajectory of the second cylinder in the second drive slot is limited and derailment failure or collision damage to parts is prevented.

[0029] Preferably, the first damper and the second damper are both rotatably connected to the lower cover of the inner shell.

[0030] This solution helps to simplify the installation process and ensure the accuracy of fit.

[0031] Preferably, the bottom of the lower cover of the inner shell near the air inlet end is a slope, and the slope includes a slope groove. When the second air door rotates until the lower channel is fully open, the second air door is entirely retracted into the slope groove, and the bottom surface of the second air door is flush with the slope.

[0032] This solution prevents the second damper from reducing the wind speed and wind volume entering the lower channel and increases the service life.

[0033] Preferably, the air outlet control unit includes a second driving element and a swing blade, wherein the second driving element is installed outside the outer shell; the second driving element cooperates to drive a slide to perform linear reciprocating motion; the swing blade includes a plurality of upper channel swing blades disposed in the upper channel and a plurality of lower channel swing blades disposed in the lower channel;

[0034] The top of the slide plate includes a plurality of third driving slide grooves, and the bottom includes a plurality of fourth driving slide grooves.

[0035] Preferably, the upper channel swing blade top rotation limit is located on the outer shell upper cover, the upper channel swing blade bottom includes an upper channel swing blade cylinder, the upper channel swing blade cylinder rotation limit is located at or passes through a through hole opened on the inner shell upper cover, the upper channel swing blade cylinder includes a third connecting rod below, and the lower end of the third connecting rod includes a third cylinder;

[0036] The bottom rotation limit of the lower channel swing blade is located on the lower cover of the outer shell, the top of the lower channel swing blade includes a lower channel swing blade cylinder, the rotation limit of the lower channel swing blade cylinder is located at or passes through a through hole opened on the lower cover of the inner shell, the upper end of the lower channel swing blade cylinder includes a fourth connecting rod, and the upper end of the fourth connecting rod includes a fourth cylinder;

[0037] The third cylinder is matched with the third driving slot, and the fourth cylinder is matched with the fourth driving slot.

[0038] In this solution, the movement trajectory of the third cylinder in the third drive slot and the movement trajectory of the fourth cylinder in the fourth drive slot are independent of each other and can be designed according to functional requirements. The rotation angle / speed of each upper channel swing blade / each lower channel swing blade can be controlled and adjusted according to functional requirements to achieve different air outlet effects, including air outlet effects that imitate natural wind.

[0039] The motion trajectory of the third cylinder in the third drive chute or the motion trajectory of the fourth cylinder in the fourth drive chute determines the rotation angle / rotation rate of each upper channel swing blade / each lower channel swing blade. The rotation angle determines the swing direction of each swing blade, and the rotation rate determines the swing rate of each swing blade.

[0040] On the premise of ensuring that there is no collision between adjacent swing blades and between the swing blades and the outer shell or inner shell, the rotation angle / rotation rate of each upper channel swing blade can be configured as needed, and the rotation angle / rotation rate of each lower channel swing blade can be configured as needed. The spacing between adjacent swing blades and between the swing blades and the outer shell or inner shell determines the air distribution volume of the gap air outlet. For example, if there are n swing blades in the upper channel, the upper channel will be divided into n+1 gap air outlets. The opening size of the gap air outlet can be adjusted within a certain range. Therefore, the upper channel or lower channel air outlet state can be designed as needed. For example, the upper channel or lower channel air outlet state can include at least the following four air distribution situations:

[0041] Case 1: The air volume of the gap outlets is the same;

[0042] Case 2: The air volume of the gap outlet shows the highest volume on one side and gradually transitions to the lowest volume on the other side;

[0043] Case 3: The air volume of the gap outlet is the largest on both sides and gradually transitions to the smallest in the middle;

[0044] Case 4: The air volume of the gap air outlet is the largest in the middle and gradually transitions to the smallest on both sides.

[0045] The swing directions of the upper channel and lower channel blades can also be designed according to needs, and can be designed into at least the following two combinations:

[0046] Combination A: The upper channel and lower channel swing blades swing in the same direction, so the upper and lower channel air outlet directions are the same;

[0047] Combination B: The upper channel blades and the lower channel blades swing in opposite directions, so the air outlet directions of the upper channel and the lower channel are opposite;

[0048] The above four situations and two combinations can be used to design different mixed air states according to functional needs. For example, the air outlet can achieve at least the following 32 air outlet states:

[0049] Air outlet state A: The upper and lower channels have the same air outlet direction.

[0050] There are 16 states: the upper channel air distribution state is any one of the states 1-4, and the lower channel air distribution state is any one of the states 1-4;

[0051] Air outlet state B: The upper channel and the lower channel have opposite air outlet directions.

[0052] It includes 16 states: the upper channel air distribution situation is any one of situations 1-4, and the lower channel air distribution situation is any one of situations 1-4.

[0053] Other types of air outlet states can also be designed according to functional requirements.

[0054] This application can achieve different air outlet states of the outflow air, and can realize general mode, natural wind mode, sweeping wind mode, breeze mode and other modes, avoiding direct blowing on the human body, and solving the physical discomfort problems such as dryness, uneven cold and hot caused by direct blowing from traditional air outlets.

[0055] Preferably, it includes a second gear, the second gear is rotatably connected to the lower cover of the inner housing, and the second driving element drives the second gear to rotate;

[0056] The bottoms of both sides of the skateboard include skateboard shoulders and racks;

[0057] The tops of both sides of the lower cover of the inner shell include horizontal bosses;

[0058] The shoulder limit of the slide plate is located on the horizontal boss, and the rack is engaged with the second gear.

[0059] In this solution, the second driving element controls the reciprocating rotational motion of the second gear, which can control and limit the horizontal reciprocating motion of the slide above the lower cover of the inner shell, thereby ensuring the horizontal reciprocating motion of the third driving chute and the fourth driving chute, thereby ensuring the regular swinging of the upper channel and the lower channel swing blades.

[0060] Preferably, the inner shell includes an inner shell side cover, and the side cover is matched with the end portions of the inner shell upper cover and the inner shell lower cover.

[0061] This solution is beneficial for simplifying the shapes of the upper cover and the lower cover of the inner shell and ensuring easy installation of the internal components of the inner shell while ensuring the integrity of the inner shell.

[0062] Preferably, the side cover divides the air outlet end into an upper channel air outlet and a lower channel air outlet.

[0063] The present invention includes at least the following technical effects:

[0064] The air inlet control unit of the present invention can realize the switching and different proportions of the upper / lower channel airflow, and the air outlet control unit can realize the mixing of the air outlet directions of the upper channel and the lower channel, adjust the direction and speed of the airflow, thereby achieving fine adjustment, and can better simulate the effect of natural wind and improve passenger comfort.

[0065] Compared with the single-channel design, the dual-channel structure of the upper and lower channels is more flexible in adjusting the wind direction and speed, and can systematically adapt to the needs of different areas in the warehouse. Through dynamic control, it can also achieve adaptation to different environments and distribute airflow on demand, further enhancing the passenger comfort experience. In this way, it effectively solves the problem of traditional air outlets blowing directly on the human body, which can easily cause dryness, uneven hot and cold, and other physical discomforts.

[0085] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0086] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0087] For example, see Figures 1-17 .

[0088] An air outlet mechanism for converting mechanical wind into natural wind comprises an outer shell, wherein the outer shell comprises an outer shell upper cover 1 and an outer shell lower cover 2 which are mutually connected, one end of the outer shell is an air inlet end, and the other end is an air outlet end;

[0089] An inner shell is installed in the outer shell, and the inner shell includes an inner shell upper cover 3 and an inner shell lower cover 4 that cooperate with each other. The inner shell divides the inner space of the outer shell into an upper channel and a lower channel;

[0090] It also includes an air inlet control unit and an air outlet control unit: the air inlet control unit adjusts the air inlet volume entering the upper channel and the lower channel; the air outlet control unit adjusts the air outlet state of the upper channel and the lower channel.

[0091] The air inlet control unit of this solution can realize the switching and different proportions of the upper / lower channel airflow, and the air outlet control unit can realize the mixing of the air outlet directions of the upper and lower channels, adjust the direction and speed of the airflow, thereby achieving fine adjustment, which can better simulate the effect of natural wind and improve passenger comfort.

[0092] Compared with the single-channel design, the dual-channel structure of the upper and lower channels is more flexible in adjusting the wind direction and speed, and can systematically adapt to the needs of different areas in the warehouse. Through dynamic control, it can also achieve adaptation to different environments and distribute airflow on demand, further enhancing the passenger comfort experience. In this way, it effectively solves the problem of traditional air outlets blowing directly on the human body, which can easily cause dryness, uneven hot and cold, and other physical discomforts.

[0093] Example 2

[0094] Based on Example 1, the air inlet control unit includes a first driving element 6, which is mounted outside the outer shell; the first driving element cooperates to drive a driving disc 8 to reciprocate around the axis, and one side of the driving disc includes a first driving slot 9 and a second driving slot 10;

[0095] The air intake control unit further includes a first damper 11, a second damper 12, a first connecting rod 13, and a second connecting rod 14. The first damper and the second damper are rotatably connected to the inner housing. The first damper limit is located in the upper channel to control its opening and closing degree, and the second damper limit is located in the lower channel to control its opening and closing degree. The first damper rotates around a first axis 15, the end of the first axis is connected to the side surface of one end of the first connecting rod, and the other side surface of the other end of the first connecting rod extends a first cylinder 17. The second damper rotates around a second axis 16, the end of the second axis is connected to the side surface of one end of the second connecting rod, and the other side surface of the other end of the second connecting rod extends a second cylinder 18.

[0096] The first cylinder is matched with the first driving slot, and the second cylinder is matched with the second driving slot.

[0097] In this scheme, the movement trajectory of the first cylinder in the first driving chute and the movement trajectory of the second cylinder in the second driving chute can be designed according to functional needs, and the air intake volume of the upper channel / lower channel can be controlled and adjusted according to functional needs. For example: the initial state is that the first air door closes the upper channel and the second air door closes the lower channel; the first adjustment stage is: the first air door closes the upper channel, and the second air door gradually opens the lower channel until it is fully open; the second adjustment stage is that the first air door gradually opens the upper channel, and the second air door keeps the lower channel open. In this stage, the free end of the first air door swings up and down at the air inlet end to adjust the ratio of the air volume entering the upper channel and the lower channel. The limit of the second adjustment stage should not exceed the critical state, which is: the state where the first air door closes the lower channel.

[0098] Example 3

[0099] Based on Example 2, it further includes a limiting element 19, which is mounted on the outside of the outer shell, and the first driving element is mounted on the limiting element. The inner side of the limiting element includes a cylindrical groove 20, and the cylindrical groove is adapted to the outer contour of the driving disc;

[0100] The other side of the drive disc includes a boss 21, which includes a cylindrical body 22 and a limiting protrusion 23 extending from the side of the cylindrical body; an external gear 24 extends from the end face of the cylindrical body; the first drive element outputs rotational motion and cooperates with the external gear;

[0101] The outer side of the limiting element includes a groove hole 25, and the groove hole includes a cylindrical portion 26 and a fan-shaped protruding portion 27;

[0102] The cylindrical body fits neatly within the cylindrical portion and rotates about its axis. The limiting protrusion is located within the sector-shaped extension and rotates about its axis. When the first driving element drives the external gear, the driving disc and boss rotate synchronously about their axis. The driving disc rotates about its axis within the confined space of the cylindrical groove, the cylindrical body rotates about its axis within the confined space of the cylindrical portion, and the limiting protrusion rotates about its axis within the sector-shaped extension.

[0103] When the first driving element drives the external gear to rotate, the driving disc and the boss rotate synchronously around the axis. The driving disc rotates around the axis in the space limited by the cylindrical groove, the cylinder rotates around the axis in the space limited by the cylindrical part, and the limiting protrusion rotates around the axis in the fan-shaped protruding part.

[0104] This solution has a protective effect: the movement path of the limiting protrusion is limited by the fan-shaped protruding part, the maximum angular range of the rotation of the drive disc is limited, the rotation range of the first drive slot and the second drive slot is limited, the movement trajectory of the first cylinder in the first drive slot is limited and derailment failure or collision damage to parts is prevented, and the movement trajectory of the second cylinder in the second drive slot is limited and derailment failure or collision damage to parts is prevented.

[0105] Example 4

[0106] Based on Example 2, the first damper and the second damper are both rotatably connected to the lower cover of the inner shell.

[0107] This solution helps to simplify the installation process and ensure the accuracy of fit.

[0108] Example 5

[0109] In addition to Example 2, the bottom of the inner housing lower cover near the air inlet is formed into a sloped surface, which includes a sloped groove 28. When the second damper rotates until the lower channel is fully open, the second damper is completely retracted into the sloped groove, and the bottom surface of the second damper is flush with the slope. This solution prevents the second damper from reducing the speed and volume of air entering the lower channel and increases its service life.

[0110] Example 6

[0111] Based on Example 1, the air outlet control unit includes a second driving element 7 and a swing blade, and the second driving element is installed on the outside of the outer shell; the second driving element cooperates to drive a slide 29 to perform linear reciprocating motion; the swing blade includes a plurality of upper channel swing blades 30 placed in the upper channel and a plurality of lower channel swing blades 31 placed in the lower channel; the top of the slide includes a plurality of third driving grooves 32, and the bottom includes a plurality of fourth driving grooves 33.

[0112] Example 7

[0113] Based on Example 6, the upper channel swing blade top rotation limit is located on the outer shell upper cover, the upper channel swing blade bottom includes an upper channel swing blade cylinder 34, the upper channel swing blade cylinder rotation limit is located in or passes through the through hole opened in the inner shell upper cover, the upper channel swing blade cylinder includes a third connecting rod 36 below, and the lower end of the third connecting rod includes a third cylinder 38;

[0114] The bottom rotation limit of the lower channel swing blade is located on the lower cover of the outer shell. The top of the lower channel swing blade includes a lower channel swing blade cylinder 35. The rotation limit of the lower channel swing blade cylinder is located at or passes through a through hole opened on the lower cover of the inner shell. The upper end of the lower channel swing blade cylinder includes a fourth connecting rod 37, and the upper end of the fourth connecting rod includes a fourth cylinder 39.

[0115] The third cylinder is matched with the third driving slot, and the fourth cylinder is matched with the fourth driving slot.

[0116] In this solution, the movement trajectory of the third cylinder in the third drive slot and the movement trajectory of the fourth cylinder in the fourth drive slot are independent of each other and can be designed according to functional requirements. The rotation angle / speed of each upper channel swing blade / each lower channel swing blade can be controlled and adjusted according to functional requirements to achieve different air outlet effects, including air outlet effects that imitate natural wind.

[0117] The motion trajectory of the third cylinder in the third drive chute or the motion trajectory of the fourth cylinder in the fourth drive chute determines the rotation angle / rotation rate of each upper channel swing blade / each lower channel swing blade. The rotation angle determines the swing direction of each swing blade, and the rotation rate determines the swing rate of each swing blade.

[0118] On the premise of ensuring that there is no collision between adjacent swing blades and between the swing blades and the outer shell or inner shell, the rotation angle / rotation rate of each upper channel swing blade can be configured as needed, and the rotation angle / rotation rate of each lower channel swing blade can be configured as needed. The spacing between adjacent swing blades and between the swing blades and the outer shell or inner shell determines the air distribution volume of the gap air outlet. For example, if there are n swing blades in the upper channel, the upper channel will be divided into n+1 gap air outlets. The opening size of the gap air outlet can be adjusted within a certain range. Therefore, the upper channel or lower channel air outlet state can be designed as needed. For example, the upper channel or lower channel air outlet state can include at least the following four air distribution situations:

[0119] Case 1: The air volume of the gap outlets is the same;

[0120] Case 2: The air volume of the gap outlet shows the highest volume on one side and gradually transitions to the lowest volume on the other side;

[0121] Case 3: The air volume of the gap outlet is the largest on both sides and gradually transitions to the smallest in the middle;

[0122] Case 4: The air volume of the gap air outlet is the largest in the middle and gradually transitions to the smallest on both sides.

[0123] The swing directions of the upper channel and lower channel blades can also be designed according to needs, and can be designed into at least the following two combinations:

[0124] Combination A: The upper channel and lower channel swing blades swing in the same direction, so the upper and lower channel air outlet directions are the same;

[0125] Combination B: The upper channel blades and the lower channel blades swing in opposite directions, so the air outlet directions of the upper channel and the lower channel are opposite;

[0126] The above four situations and two combinations can be used to design different mixed air states according to functional needs. For example, the air outlet can achieve at least the following 32 air outlet states:

[0127] Air outlet state A: The upper and lower channels have the same air outlet direction.

[0128] There are 16 states: the upper channel air distribution state is any one of the states 1-4, and the lower channel air distribution state is any one of the states 1-4;

[0129] Air outlet state B: The upper channel and the lower channel have opposite air outlet directions.

[0130] It includes 16 states: the upper channel air distribution situation is any one of situations 1-4, and the lower channel air distribution situation is any one of situations 1-4.

[0131] Other types of air outlet states can be designed according to functional needs. This application can achieve different air outlet states of the outflow airflow, and can realize modes such as general mode, natural wind mode, sweeping wind mode, and breeze mode, avoiding direct blowing on the human body and solving the problems of dryness, uneven hot and cold, and other physical discomfort caused by direct blowing from traditional air outlets.

[0132] Example 8

[0133] Based on Example 6, it includes a second gear 40, the second gear is rotatably connected to the lower cover of the inner housing, and the second driving element drives the second gear to rotate;

[0134] The bottom of both sides of the slide include slide shoulders 41 and racks 42;

[0135] The top of both sides of the lower cover of the inner shell includes horizontal bosses 43;

[0136] The shoulder limit of the slide plate is located on the horizontal boss, and the rack is engaged with the second gear.

[0137] In this solution, the second driving element controls the reciprocating rotational motion of the second gear, which can control and limit the horizontal reciprocating motion of the slide above the lower cover of the inner shell, thereby ensuring the horizontal reciprocating motion of the third driving chute and the fourth driving chute, thereby ensuring the regular swinging of the upper channel and the lower channel swing blades.

[0138] Example 9

[0139] Based on Example 1, the inner housing includes an inner housing side cover 5, which fits over the ends of the inner housing upper and lower covers. This side cover divides the air outlet into an upper channel outlet and a lower channel outlet. While maintaining the integrity of the inner housing, this solution facilitates the simplification of the shape of the inner housing upper and lower covers and ensures easy installation of the inner housing's internal components.
