Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air outlet component, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] Currently, ducted air conditioners are the mainstream type of indoor unit terminal in central air conditioning systems due to their aesthetically pleasing installation and space-saving design. The increasingly popular continuous air outlet style in recent years further enhances their minimalist and sophisticated look, making them highly favored by younger consumers. However, some related technologies incorporate air guide vanes at the air outlets. These vanes open or close by rotating. Because the length of the vane is designed to match the length of the elongated air outlet, its relatively long length can lead to issues such as wobbling or misalignment after rotation, resulting in incomplete sealing of the air outlet and causing condensation or air leakage.

[0057] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0058] refer to Figure 1In some embodiments, the air outlet assembly includes an air outlet frame 1, an air guide plate 2, and a locking mechanism 300, wherein the locking mechanism 300 includes a locking element 3.

[0059] The air outlet frame 1 has an air outlet 11.

[0060] The air guide plate 2 is rotatably disposed on the air outlet frame 1, and the air guide plate 2 is configured to rotate to block the air outlet 11 or avoid the air outlet 11.

[0061] The locking element 3 is configured to lock the air guide plate 2 after it is rotated to a preset position.

[0062] In the above embodiment, an air outlet 11 is formed on the air outlet frame 1 for airflow discharge. The air guide plate 2 is rotatably disposed on the air outlet frame 1 and is configured to rotate around a set axis to selectively block or avoid the air outlet 11. By rotating the air guide plate 2, the air outlet state of the air outlet assembly can be adjusted to control the airflow volume or whether air is being discharged. The locking member 3 is configured to lock the air guide plate 2 after it rotates to a preset position to restrict the free rotation of the air guide plate 2 or its deflection due to airflow disturbance.

[0063] In the above embodiment, after the air guide plate 2 rotates to the preset position, the air guide plate 2 is locked by the locking member 3, which can effectively prevent the air guide plate 2 from vibrating or deflecting under the action of airflow, thereby solving the problem of abnormal noise caused by the instability of the air guide plate 2.

[0064] Furthermore, since the air guide plate 2 is used to block the air outlet 11 when closed, if the air guide plate 2 vibrates or shifts, the air outlet 11 will not be properly sealed, which may lead to problems such as air leakage and uneven airflow. In addition, in a humid and hot environment, condensation may occur at the air outlet 11, and the condensate may seep into the equipment, affecting the safe operation and service life of the equipment.

[0065] Therefore, by setting the locking component 3 to position and lock the air guide plate 2, not only is the stability of the air guide plate 2 in the preset position improved, but the sealing performance of the air outlet 11 is also enhanced, thereby effectively reducing the occurrence of air leakage, reducing the risk of condensation, and improving the overall reliability and sealing of the air outlet assembly.

[0066] refer to Figures 2 to 5 In some embodiments, the air outlet assembly also includes a first round 4.

[0067] The first wheel 4 is connected to the air guide plate 2 to drive the air guide plate 2 to rotate. The first wheel 4 is provided with a locking groove 41.

[0068] The locking component 3 is configured to be inserted into the locking groove 41 after the first wheel 4 drives the air guide plate 2 to rotate to a preset position.

[0069] In the above embodiment, the first wheel 4 rotates to drive the air guide plate 2 to rotate, thereby blocking or avoiding the air outlet 11. The first wheel 4 has a circumferential locking groove 41, the specific position of which can be adjusted according to the rotation angle of the air guide plate 2. After the first wheel 4 drives the air guide plate 2 to a preset position (the air guide plate 2 completely blocks the air outlet 11, completely avoids the air outlet 11, or opens to a certain angle), the locking member 3 is inserted into the locking groove 41 to achieve mechanical locking of the air guide plate 2, preventing it from shifting or shaking due to external airflow disturbances or other vibration factors. The method of locking the air guide plate 2 by inserting the locking member 3 into the locking groove 41 is simple in structure and highly reliable.

[0070] In some embodiments, the air outlet assembly further includes a top block 7 and a connector 8.

[0071] The first end of the connector 8 is connected to the top block 7, the second end of the connector 8 is connected to the locking member 3, and the part of the connector 8 located at the first end and the second end is rotatably connected to the air outlet frame 1.

[0072] The top block 7 is configured to reciprocate under the action of an external force, so that the connecting member 8 rotates clockwise or counterclockwise, so as to insert the locking member 3 into the locking groove 41 or pull the locking member 3 out of the locking groove 41.

[0073] In the above embodiment, the first end of the connector 8 is connected to the top block 7, and the second end of the connector 8 is connected to the locking member 3. The portion of the connector 8 located at the first and second ends is a hinge portion 81, which is rotatably connected to the air outlet frame 1, allowing the connector 8 to rotate around the hinge portion 81 as a fulcrum. The top block 7, the locking member 3, and the connector 8 constitute a lever mechanism, with the top block 7 and the locking member 3 moving in opposite directions. When the top block 7 moves along the first direction, the connector 8 rotates accordingly, causing the locking member 3 to move along the second direction; when the top block 7 moves along the second direction, the locking member 3 moves along the first direction. The first and second directions are opposite to each other.

[0074] The top block 7, the connecting part 8, and the locking part 3 together constitute a lever mechanism. The reciprocating motion of the top block 7 drives the connecting part 8 to rotate, thereby controlling the insertion and removal action of the locking part 3. This enables the locking part 3 to automatically lock or unlock after the air guide plate 2 rotates to a preset position. This linkage structure is simple and reliable, and is easy to integrate into the air outlet assembly to realize the automated operation of locking the air guide plate 2.

[0075] In some embodiments, connector 8 includes a link or hinge.

[0076] In some embodiments, the air outlet assembly further includes a second wheel 5.

[0077] The second wheel 5 extends radially outward and is provided with a pushing part 51. The second wheel 5 is configured to rotate so that the pushing part 51 pushes the top block 7, and in the state where the pushing part 51 pushes the top block 7 at its farthest end, the locking member 3 is inserted into the locking groove 41.

[0078] In the above embodiment, the second wheel 5 is configured to rotate under the drive of the power component, so that the jacking part 51 contacts the top block 7 and applies a thrust during rotation. When the jacking part 51 rotates to its farthest position, it applies the maximum jacking force to the top block 7, thereby locking the air guide plate 2 by means of the locking member 3 inserted into the locking groove 41 through the connecting member 8.

[0079] In the above embodiment, the second wheel 5 rotates to drive the pusher 51 to push the top block 7, and then the locking member 3 is inserted into the locking groove 41 through the connecting member 8 to realize the automatic locking of the air guide plate 2; when operating in the opposite direction, the locking member 3 can be automatically pulled out to unlock the air guide plate 2, so as to facilitate the air guide plate 2 to rotate to different preset positions and realize the automatic locking and unlocking of the air guide plate 2.

[0080] In the above embodiment, through the rotational motion of the second wheel 5, the pusher 51 can accurately push the top block 7 according to the preset position without manual intervention, thereby improving the automation level and reliability of the entire air outlet assembly.

[0081] In some embodiments, the pushing part 51 includes a farthest end and a nearest end, the farthest end being furthest from the center of the second wheel 5, and the nearest end being closest to the center of the second wheel 5.

[0082] In some embodiments, the axis of the first wheel 4 is parallel to the axis of the second wheel 5 and is spaced apart.

[0083] In some embodiments, the air outlet assembly further includes a fixing plate 9, a top rod 71, and an elastic element 10.

[0084] The fixing plate 9 is located on the air outlet frame 1.

[0085] The first end of the push rod 71 is connected to the top block 7, and the second end of the push rod 71 passes through the fixing plate 9 and is connected to the first end of the connector 8.

[0086] The elastic element 10 is provided on the top rod 71 and is located between the top block 7 and the fixed plate 9.

[0087] In the above embodiment, during the process of pushing the top block 7 from the nearest end to the farthest end of the pushing part 51, the top block 7 moves in the first direction along the axial direction of the pushing rod 71. The elastic member 10 is compressed by the top block 7 and the fixing plate 9. The top block 7 drives the connecting member 8 to lock the locking member 3, so that the locking member 3 is inserted into the locking groove 41. During the process of pushing the top block 7 from the farthest end to the nearest end of the pushing part 51 (i.e., the return phase), the restoring force of the elastic member 10 pushes the top block 7 to move in the second direction, driving the connecting member 8 to lock the locking member 3, so that it is pulled out of the locking groove 41, completing the unlocking action.

[0088] In the above embodiment, during the process of the pusher 51 pushing the top block 7, the elastic element 10 absorbs part of the force and plays a buffering role. Furthermore, during the return stroke after the pusher 51 completes its pushing action, the top block 7 automatically resets due to the elastic force of the elastic element 10. The linkage connector 8 then drives the locking element 3 to disengage from the locking groove 41, achieving automatic unlocking of the air guide plate 2 without the need for additional driving components.

[0089] In some embodiments, the starting end and the ending end of the pushing part 51 are both the closest ends of the pushing part 51.

[0090] The farthest end refers to the farthest point of the pushing part 51 in the radial direction from the center of the second wheel 5, and the nearest end refers to the nearest point of the pushing part 51 in the radial direction from the center of the second wheel 5.

[0091] In some embodiments, the farthest end of the pushing portion 51 is located between the starting end and the ending end of the pushing portion 51.

[0092] In some embodiments, the locking member 3 is configured to move toward the locking groove 41 until it is inserted into the locking groove 41 during the process of pushing the top block 7 from the nearest end to the farthest end of the pushing portion 51.

[0093] The locking member 3 is also configured to move away from the locking groove 41 until it disengages from the locking groove 41 during the process of pushing the top block 7 from the farthest end to the nearth end of the pushing part 51.

[0094] In the above embodiment, when the second wheel 5 rotates, as the pushing part 51 pushes the top block 7 from the nearest end to the farthest end, the top block 7 moves along the first direction and drives the locking part 3 to move towards the locking groove 41 through the connecting part 8 until the locking part 3 is fully inserted into the locking groove 41, thereby achieving mechanical locking of the air guide plate 2. When the second wheel 5 rotates, as the pushing part 51 pushes the top block 7 from the farthest end to the nearest end, the top block 7 moves along the second direction under the reset action of the elastic member 10 and drives the locking part 3 away from the locking groove 41 through the connecting part 8, ultimately causing it to disengage from the locking groove 41 and completing the unlocking action.

[0095] In the above embodiments, the locking member 3 can achieve "locking-holding-unlocking" of the air guide plate 2 during the reciprocating movement of the top block 7 between the nearest and farthest ends of the pushing part 51, without the need for additional drive mechanisms or complex control logic, thus improving the automation level and response efficiency of the air outlet assembly in the opening and closing control of the air guide plate 2. At the same time, the structure is compact and reliable, which helps to improve the overall operational stability and sealing performance of the air outlet assembly.

[0096] In some embodiments, the air outlet assembly further includes a third wheel 6.

[0097] The third wheel 6 is provided with a meshing tooth section 61, which meshes with the meshing teeth on the first wheel 4 to drive the first wheel 4 to rotate.

[0098] In the above embodiment, the third wheel 6 is the driving wheel, and the first wheel 4 is the driven wheel. The third wheel 6 can serve as an intermediate transmission component, transmitting power from an external power component (such as a motor) to the first wheel 4, thereby driving the air guide plate 2 to adjust its angle. The meshing tooth segment 61 can be designed as a partial circle according to the transmission ratio requirements to meet the adjustment requirements of the air guide plate 2 under different air outlet conditions. The third wheel 6 and the first wheel 4 are connected by gear meshing, which has the advantages of stable transmission, rapid response, and accurate positioning, and can effectively improve the control accuracy and operational reliability of the air guide plate 2 during rotation.

[0099] In some embodiments, the air outlet assembly further includes a power component that is driven to the third wheel 6. Optionally, the power component includes a motor.

[0100] In some embodiments, the third wheel 6 is coaxially arranged with the second wheel 5. The third wheel 6 is also provided with a toothless segment 62. The span of the toothless segment 62 in the circumferential direction of the third wheel 6 is the same as the span of the farthest end to the nearest end of the pushing part 51 in the circumferential direction of the second wheel 5. The pushing part 51 pushes the top block 7 from the nearest end to the farthest end, corresponding to the beginning end of the toothless segment 62 being closest to the first wheel 4 and the end end of the toothless segment 62 being closest to the first wheel 4.

[0101] In the above embodiment, the third wheel 6 and the second wheel 5 are coaxially arranged and share the same rotation axis, thus achieving synchronous rotation. The third wheel 6 is provided with a toothless section 62, which extends circumferentially along the third wheel 6 and has a certain span in the circumferential direction. The span of the toothless section 62 corresponds to the circumferential span of the nearest end to the farthest end of the pushing part 51 on the second wheel 5. When the nearest end of the pushing part 51 begins to push the top block 7 to the farthest end, the third wheel 6 rotates synchronously, causing the toothless section 62 to rotate from its starting end, which is closest to the first wheel 4, to its ending end, which is closest to the first wheel 4. This rotation process is synchronized with the pushing action. Since the toothless section 62 does not mesh with the teeth on the first wheel 4, it will not drive the first wheel 4 to rotate during this process, and the position of the air guide plate 2 will not change, thus avoiding the air guide plate 2 from rotating due to gear meshing during locking or unlocking, which could cause malfunction.

[0102] In the above embodiment, by setting a toothless section 62 on the third wheel 6 that matches the circumferential span of the pushing part 51, and coaxially connecting the third wheel 6 with the second wheel 5, the precise control of the locking mechanism's action and the stable operation of the transmission system are achieved; this not only improves the coordination and reliability of the air guide plate 2 in the opening, closing and locking process, but also optimizes the spatial layout and enhances the integration of the system.

[0103] In some embodiments, there are two preset positions, two locking slots 41, two toothless sections 62, and two pushing parts 51. Each preset position corresponds to one locking slot 41, one toothless section 62, and one pushing part 51. When the air guide plate 2 is in one of the preset positions, the farthest end of one of the pushing parts 51 pushes the top block 7, which causes the locking member 3 to be inserted into one of the locking slots 41.

[0104] In the above embodiment, when the air guide plate 2 is in one of the preset positions, the nearest end of a pusher 51 pushes the top block 7 to the farthest end. The top block 7, through the connector 8, drives the locking member 3 to insert into a corresponding locking groove 41, thereby locking the air guide plate 2. During the process of the pusher 51 pushing the top block 7 from the farthest end to the nearest end, the top block 7, through the connector 8, drives the locking member 3 to be pulled out of the locking groove 41, thereby unlocking the air guide plate 2. Simultaneously, the locking and unlocking process of the air guide plate 2 at this preset position corresponds to a toothless segment 62 on the third wheel 6.

[0105] When the air guide plate 2 is in another preset position, the corresponding pusher 51 pushes the top block 7 from its nearest to its farthest end. The top block 7, through the connector 8, drives the locking member 3 to insert into the corresponding locking groove 41, thereby locking the air guide plate 2. As the other pusher 51 pushes the top block 7 from its farthest end to its nearest end, the top block 7, through the connector 8, drives the locking member 3 to be pulled out of the corresponding locking groove 41, thereby unlocking the air guide plate 2. Simultaneously, the locking and unlocking process of the air guide plate 2 in this other preset position corresponds to another toothless section 62 on the third wheel 6.

[0106] In the above embodiments, through the coaxial linkage of the second wheel 5 and the third wheel 6, the synchronous cooperation of the push part 51 and the toothless section 62, and the corresponding setting of multiple sets of locking structures, the air outlet assembly can achieve stable locking and automatic unlocking of the air guide plate 2 in multiple preset positions, effectively improving the sealing performance, ease of operation and automation level of the air outlet assembly.

[0107] In some embodiments, the meshing toothed section 61 is located between two toothless sections 62, wherein one toothless section 62 corresponds to a preset position for locking and unlocking the locking member 3 with a locking groove 41, and the other toothless section 62 corresponds to another preset position for locking and unlocking the locking member 3 with another locking groove 41.

[0108] In some embodiments, the preset position includes a first preset position and a second preset position, the locking groove 41 includes a first locking groove 411 and a second locking groove 412, the toothless section 62 includes a first toothless section 621 and a second toothless section 622, the meshing toothed section 61 is disposed between the first toothless section 621 and the second toothless section 622, and the pushing part 51 includes a first pushing part 511 and a second pushing part 512.

[0109] The process of the first pushing part 511 pushing the top block 7 from its closest end to its farthest end corresponds to the state where the first toothless section 621 is closest to the first wheel 4 and the air guide plate 2 is in the first preset position. When the top block 7 is pushed by the farthest end of the first pushing part 511, the locking member 3 is inserted into the first locking groove 411, locking the air guide plate 2 in the first preset position. This process corresponds to the stroke of the first toothless section 621. When it is necessary to change the air guide plate 2 from the first preset position to the second preset position, the top block 7 is pushed from its farthest end to its closest end, pulling the locking member 3 out of the first locking groove 411, unlocking the air guide plate 2 in the first preset position. This process corresponds to the reverse stroke of the first toothless section 621. Since the first toothless section 621 has no teeth, neither the forward nor reverse stroke of the first toothless section 621 will cause the first wheel 4 to rotate, keeping the air guide plate 2 in the first preset position.

[0110] The next segment after the first toothless section 621 is the meshing toothed section 61. Then, through the meshing toothed section 61 meshing with the teeth on the first wheel 4, the air guide plate 2 rotates and reaches the second preset position. The span of the meshing toothed section 61 on the first wheel 4 corresponds to the rotation of the air guide plate 2 from the first preset position to the second preset position. At this time, the second toothless section 622 is close to the teeth on the first wheel 4.

[0111] The process of the second pushing part 512 pushing the top block 7 from its closest end to its farthest end corresponds to the state where the second toothless section 622 is closest to the first wheel 4 and the air guide plate 2 is in the second preset position. When the second pushing part 512 pushes the top block 7 from its farthest end, the locking member 3 is inserted into the second locking groove 412, locking the air guide plate 2 in the second preset position. This process corresponds to the stroke of the second toothless section 622. When it is necessary to change the air guide plate 2 from the second preset position to the first preset position, the second pushing part 512 first pushes the top block 7 from its farthest end to its closest end, pulling the locking member 3 out of the second locking groove 412, unlocking the air guide plate 2 in the second preset position. This process corresponds to the reverse stroke of the second toothless section 622. Since the second toothless section 622 has no teeth, neither the forward nor reverse stroke of the second toothless section 622 will cause the first wheel 4 to rotate, keeping the air guide plate 2 in the second preset position.

[0112] In the above embodiments, the air outlet assembly can achieve stable locking and automatic unlocking of the air guide plate 2 in multiple preset positions, which improves the control accuracy and sealing performance of the air outlet assembly in different operating modes. At the same time, it optimizes the spatial layout of the transmission structure and the automatic control logic, resulting in a reasonable structure, reliable operation, and flexible control.

[0113] In some embodiments, the reciprocating motion direction of the top block 7 is parallel to the direction in which the locking member 3 moves into or out of the locking groove 41.

[0114] In the above embodiment, the reciprocating motion direction of the top block 7 is parallel to the direction in which the locking member 3 moves to insert into or disengage from the locking groove 41. When the top block 7 is pushed by the push part 51 or reset under the action of the elastic member 10, its motion direction is parallel to and opposite to the insertion and removal direction of the locking member 3, thereby ensuring that the connecting member 8 is subjected to uniform force and moves smoothly during the transmission process, reducing mechanical jamming or wear caused by directional deviation.

[0115] Some embodiments of this utility model also provide an indoor air conditioning unit, which includes the above-described air outlet assembly.

[0116] The air conditioner indoor unit provided in this embodiment includes the air outlet assembly provided in this embodiment, and accordingly has the beneficial effects of the air outlet assembly.

[0117] In some embodiments, the air outlet 11 includes a first air outlet and a second air outlet, and the air guide plate 2 is configured to rotate to block the first air outlet and avoid the second air outlet, or to block the second air outlet and avoid the first air outlet.

[0118] In the above embodiments, the air guide plate 2 is configured to rotate to block the first air outlet and avoid the second air outlet, or to block the second air outlet and avoid the first air outlet. The same air guide plate 2 can block or open different air outlets, simplifying the structure and reducing costs.

[0119] Since the air guide plate 2 is used to block the air outlet 11 when closed, if the air guide plate 2 vibrates or shifts, the air outlet 11 will not be sealed properly, which may lead to problems such as air leakage and uneven air distribution. In addition, in a humid and hot environment, condensation may occur at the air outlet 11, and the condensate may seep into the equipment, affecting the safe operation and service life of the equipment.

[0120] Therefore, by setting the locking component 3 to position and lock the air guide plate 2, not only is the stability of the air guide plate 2 in the preset position improved, but the sealing performance of the air outlet 11 is also enhanced, thereby effectively reducing the occurrence of air leakage, reducing the risk of condensation, and improving the overall reliability and sealing of the air outlet assembly.

[0121] Because some related technologies use ducted air conditioners with only one air outlet, for some apartment layouts where the air conditioner is installed in the ceiling between the dining room and living room, users usually need to install two units, one with an air outlet facing the dining room and the other facing the living room, with a return air vent at the bottom. This results in high overall unit costs and an unsightly appearance.

[0122] Therefore, in some embodiments, the indoor unit of the air conditioner is provided with at least two air outlets, and the air outlets can have different air outlet directions to meet various air supply modes.

[0123] In some embodiments, the air outlet direction of at least one air outlet is opposite to that of another air outlet, and air is simultaneously delivered in two opposite directions to meet user needs.

[0124] In some embodiments, at least two air guide plates 2 are provided at the air outlet 11, and the air outlet 11 is sealed by the interlocking of multiple air guide plates 2; by setting a locking member 3 to lock the air guide plate 2 after it rotates to a preset position, the air guide plate 2 can be effectively prevented from vibrating or deflecting under the action of airflow, thereby alleviating the problem of abnormal noise caused by the instability of the air guide plate 2; and also alleviating the problem of poor sealing caused by the long length and insufficient rigidity of the air guide plate 2, as well as the problem of condensation and air leakage caused by poor sealing at the joints between multiple air guide plates 2.

[0125] In some embodiments, the air outlet 11 includes a first air outlet and a second air outlet. The first air outlet has a horizontal air outlet direction, and the second air outlet has a downward air outlet direction. The first air outlet is located above the second air outlet. Two air guide plates 2 are arranged vertically at the first air outlet, and each air guide plate is equipped with a locking mechanism. The two air guide plates 2 cooperate to close the first air outlet. One air guide plate 2 rotates upward and the other air guide plate 2 rotates downward, which can completely open the first air outlet, and the other air guide plate 2 can close the second air outlet due to its downward rotation.

[0126] The following is in conjunction with the appendix Figures 1 to 5 This document describes in detail some specific embodiments of an air conditioner indoor unit.

[0127] refer to Figure 1 The indoor unit of the air conditioner includes a fan 200, a heat exchanger 100, and an air outlet assembly. The air outlet assembly includes an air outlet frame 1, an air guide plate 2, and a locking mechanism 300. The air outlet frame 1 has an air outlet 11. The air guide plate 2 is rotatably mounted on the air outlet frame 1 and is configured to rotate to block or avoid the air outlet 11. The locking mechanism 300 is configured to lock the air guide plate 2 after it has rotated to a preset position. The fan 200 provides power to allow return air to enter the indoor unit. After heat exchange in the heat exchanger 100, the return air is discharged through the air outlet 11 of the air outlet assembly.

[0128] refer to Figures 2 to 5 The locking mechanism 300 includes a first wheel 4, a second wheel 5, a third wheel 6, a top block 7, a locking component 3, a connecting component 8, and an elastic component 10.

[0129] The first wheel 4 has circumferentially meshing teeth, and two locking grooves 41 are spaced apart on the first wheel 4, namely the first locking groove 411 and the second locking groove 412. No meshing teeth are provided at the positions of the two locking grooves 41. The angle s of the central angle corresponding to the arc segment between the two locking grooves 41 is denoted as 90 degrees. Optionally, the angle s is equal to 90 degrees. The first wheel 4 is connected to the air guide plate 2.

[0130] The third wheel 6 and the second wheel 5 are concentric wheels, connected to the same drive shaft, and rotate synchronously. The radii of the third wheel 6 and the second wheel 5 are the same.

[0131] The second wheel 5 has two pushing parts 51, namely the first pushing part 511 and the second pushing part 512. The two pushing parts 51 have identical structures and both extend away from the center of the second wheel 5. Each pushing part 51 has two ends, a starting end and an ending end, which are closest to the center of the second wheel 5 and can also be called the closest end. The starting end and the ending end of the pushing part 51 can be interchanged. When the second wheel 5 rotates clockwise, the end passed first is the starting end, and the end passed later is the ending end. When the second wheel 5 rotates counterclockwise, the end passed first is the starting end, and the end passed later is the ending end. Between the starting end and the ending end is the part farthest from the center of the second wheel 5, called the farthest end. The angle between the central angle of the arc segment corresponding to the farthest end and the starting end is r, and the angle between the central angle of the arc segment corresponding to the farthest end and the ending end is r.

[0132] The third gear 6 has two toothless sections 62, namely the first toothless section 621 and the second toothless section 622. The third gear 6 also has a meshing toothed section 61, which is located between the two toothless sections 62. The angle of the central angle corresponding to the meshing toothed section 61 is s. The two toothless sections 62 have the same radian and the corresponding central angle is r.

[0133] The top block 7 and the locking element 3 are respectively connected to the two ends of the connecting element 8. A hinge part 81 is provided in the middle of the connecting element 8. The connecting element 8 is hinged to the air outlet frame 1 through the hinge part 81 to form an equal-arm lever mechanism. The fixing plate 9 is provided on the air outlet frame 1. The tail of the top block 7 is connected to one end of the top rod 71. The other end of the top rod 71 passes through the fixing plate 9 and is connected to the end of the connecting element 8. An elastic element 10 is provided on the top rod 71. The elastic element 10 abuts against the top block 7 and the fixing plate 9 respectively. The head of the top block 7 has a spherical structure for contacting the second wheel 5.

[0134] refer to Figure 2 The air guide plate 2 is in a first preset position (optionally, the air guide plate 2 is vertically downward) and locked. The farthest end of the first pushing part 511 of the second wheel 5 pushes the head of the top block 7. The top block 7 is located at the farthest point of movement in the first direction. The elastic member 10 is compressed between the top block 7 and the fixed plate 9 by the pushing force of the top block 7. Under the action of the top block 7, the connecting member 8 pushes the locking member 3 out in the second direction. The locking member 3 is located at the farthest point of movement in the second direction and is inserted into the first locking groove 411, thereby locking the air guide plate 2 in the first preset position. At the same time, in this state, one end of the first toothless section 621 of the third wheel 6 is closest to the first wheel 4. The first direction and the second direction are two opposite directions.

[0135] refer to Figure 3 The air guide plate 2 is in the first preset position and is in the unlocked state. From Figure 2 The air guide plate 2 shown is in the first preset position and in a locked state, until... Figure 3 The air guide plate 2 shown is in the first preset position and in the unlocked state. Both the second wheel 5 and the third wheel 6 rotate counterclockwise by an angle r. During the counterclockwise rotation of the second wheel 5 by an angle r, the first pushing part 511 pushes the top block 7 from the farthest end to the nearest end. During this process, the top block 7 moves in the second direction. When the nearest end of the first pushing part 511 contacts the top block 7, the pushing force of the first pushing part 511 on the top block 7 is minimal. At the same time, during the counterclockwise rotation of the second wheel 5 by an angle r, the top block 7 is also subjected to the elastic force of the elastic member 10 until the top block 7 moves to the farthest point in the second direction. The connecting member 8 drives the locking member 3 to move to the farthest point in the first direction and pulls it out of the first locking groove 411, realizing the self-locking release and unlocking the air guide plate 2 in the first preset position. While the second wheel 5 rotates counterclockwise by an angle r, the third wheel 6 also rotates counterclockwise by an angle r. This rotation process brings one end of the first toothless segment 621 closest to the first wheel 4, until the other end of the first toothless segment 621 is closest to the first wheel 4. Because the first toothless segment 621 is closest to the first wheel 4 during the counterclockwise rotation of the third wheel 6, it will not mesh with the first wheel 4, the first wheel 4 will not rotate, and the position of the air guide plate 2 will remain unchanged. At this time, the meshing tooth segment 61 of the third wheel 6 is about to enter contact with the meshing teeth of the first wheel 4.

[0136] refer to Figure 4 The air guide plate 2 switches from the first preset position to the second preset position (optionally, the air guide plate 2 is placed horizontally) and is in the unlocked state. When the air guide plate 2... Figure 3 The first preset position shown is switched to Figure 4During the process of reaching the second preset position, both the second wheel 5 and the third wheel 6 rotate counterclockwise by an angle of s. During this process, the second wheel 5 rotates counterclockwise, and the portion between the first pushing part 511 and the second pushing part 512 contacts the top block 7 until the closest end of the second pushing part 512 contacts the top block 7. During the counterclockwise rotation of the second wheel 5, because the portion between the first pushing part 511 and the second pushing part 512 is in contact with the top block 7, the top block 7 will not move in the first direction. The locking member 3 also remains disengaged from the locking groove 41 during the counterclockwise rotation of the second wheel 5, and the air guide plate 2 remains unlocked. Simultaneously with the counterclockwise rotation of the second wheel 5, the third wheel 6 also rotates counterclockwise by an angle of s, corresponding to the central angle of the meshing tooth segment 61. During this process, the meshing tooth segment 61 engages with the meshing teeth of the first wheel 4, causing the first wheel 4 to rotate clockwise until the air guide plate 2 switches from the first preset position to the second preset position. At this time, the end of the meshing tooth segment 61 is about to leave the meshing teeth on the first wheel 4, and the beginning of the second toothless segment 622 is closest to the first wheel 4. Furthermore, the meshing tooth segment 61 engages with the meshing teeth on the first wheel 4, causing the first wheel 4 to rotate clockwise by an angle of s. At this time, the second locking groove 412 of the first wheel 4 is located near the locking member 3.

[0137] refer to Figure 5 The air guide plate 2 is in the second preset position and locked. When the air guide plate 2 moves from... Figure 4 The second preset position shown is in the unlocked state; switch to the position shown. Figure 5 As shown in the second preset position and in the locked state, the second wheel 5 and the third wheel 6 continue to rotate counterclockwise by an angle r. During the counterclockwise rotation of the second wheel 5 by angle r, the second pushing part 512 pushes the top block 7 from the nearest end to the farthest end. During this process, the top block 7 moves to the farthest point in the first direction. The elastic member 10 is compressed between the top block 7 and the fixed plate 9 by the pushing force of the top block 7. Under the action of the top block 7, the connecting member 8 pushes the locking member 3 out in the second direction. The locking member 3 moves to the farthest point in the second direction and inserts into the second locking groove 412, thereby locking the air guide plate 2 in the second preset position. While the second wheel 5 rotates, the third wheel 6 rotates synchronously. Since the second toothless section 622 is closest to the position of the first wheel 4 during this rotation, it will not mesh with the first wheel 4. The first wheel 4 does not rotate, and the position of the air guide plate 2 remains unchanged, always in the second preset position, thus completing the self-locking of the air guide plate 2 in the second preset position.

[0138] The above Figure 2 and Figure 5The process of the air guide plate 2 switching from a locked state in a first preset position to a locked state in a second position is described. During this process, the second wheel 5 and the third wheel 6 rotate counterclockwise. The first wheel 4 rotates clockwise, causing the air guide plate 2 to switch from the first preset position to the second preset position.

[0139] When the air guide plate 2 needs to switch from the locked state of the second preset position to the locked state of the first preset position, firstly, the second wheel 5 and the third wheel 6 are rotated clockwise while the first wheel 4 remains stationary. The locking element 3 is pulled out of the second locking groove 412, unlocking the air guide plate 2. Then, the second wheel 5 and the third wheel 6 continue to rotate clockwise while the first wheel 4 rotates counterclockwise, causing the air guide plate 2 to rotate from the second preset position to the first preset position, until it is located at the first preset position, where the first locking groove 411 corresponds to the locking element 3. Then, the second wheel 5 and the third wheel 6 continue to rotate clockwise while the first wheel 4 remains stationary, until the locking element 3 is inserted into the first locking groove 411, locking the air guide plate 2 at the first preset position and restoring it to the first preset position. Figure 2 The state shown.

[0140] According to the descriptions of the above embodiments, during the switching process of the air guide plate 2 from the second preset position to the first preset position, the second wheel 5 and the third wheel 6 rotate clockwise, and the first wheel 4 rotates counterclockwise. During the switching process of the air guide plate 2 from the first preset position to the second preset position, the second wheel 5 and the third wheel 6 rotate counterclockwise, and the first wheel 4 rotates clockwise.
