[0058] The present utility model provides an air supply device. Among them, the air supply device can be a heater or an air conditioner, and the specific corresponding product of the air conditioner can be a cabinet of a split air conditioner or a split air conditioner including a cabinet.

[0059] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the air supply device includes:

[0060] A housing 100, formed with an air outlet 101 extending along the height direction of the air supply device, and first end walls 110 and second end walls 120 are respectively provided at both ends of the air outlet 101 in the height direction;

[0061] The first swing blade 210 is rotatably arranged at the air outlet 101 and is correspondingly arranged opposite to the first end wall 110. The first swing blade 210 has an initial position that fits against the first end wall 110 and can swing towards the second end wall 120.

[0062] A plurality of second swing blades 310 distributed along the height direction of the air supply device, the plurality of second swing blades 310 are located between the first swing blade 210 and the second end wall 120 and are connected by a connecting rod 320.

[0063] It can be understood that the first end wall 110 and the second end wall 120 are oppositely arranged in the height direction of the air supply device. One of the first end wall 110 and the second end wall 120 is the top wall of the air outlet 101, and the other is the bottom wall of the air outlet 101. When the first swing blade 210 is in the initial position that fits against the first end wall 110, if the first end wall 110 is the top wall of the air outlet 101, then the second end wall 120 is the bottom wall of the air outlet 101. The rotation of the first swing blade 210 towards the second end wall 120 is also a downward rotation, that is, the first swing blade 210 can rotate downward and is limited by the first end wall 110 and cannot rotate upward; if the first end wall 110 is the bottom wall of the air outlet 101, then the second end wall 120 is the top wall of the air outlet 101. The rotation of the first swing blade 210 towards the second end wall 120 is also an upward rotation, that is, the first swing blade 210 can rotate upward and is limited by the first end wall 110 and cannot rotate downward. Since the plurality of second swing blades 310 are connected by the connecting rod 320, when the connecting rod 320 is driven to displace in the height direction of the air supply device, the plurality of second swing blades 310 can swing synchronously.

[0064] As Figures 1 to 3 shown, when the first end wall 110 is the top wall of the air outlet 101, both the first swing blade 210 and the second swing blade 310 rotate downward, which can guide the hot air to flow downward. Moreover, the first swing blade 210 can press down the hot air at the top end side of the air outlet 101. Thus, the hot air in the entire area of the air outlet 101 can be pressed down, making the hot air flow towards the ground. Subsequently, under the trend of its own upward movement, the hot air can fully diffuse in the height direction of the indoor environment, so that the hot air can be fully diffused in each area of the indoor environment. In addition, under the action of the wall attachment effect, the hot air flowing towards the ground can flow along the ground, so that the hot air can be more efficiently diffused in the indoor environment.

[0065] When the first end wall 110 is the bottom wall of the air outlet 101, both the first swing blade 210 and the second swing blade 310 rotate upward, which can guide the cold air to blow upward. Moreover, the first swing blade 210 can lift the cold air at the bottom end side of the air outlet 101. Thus, the cold air in the entire area of the air outlet 101 can be lifted, causing the cold air to flow towards the ceiling. Subsequently, under the trend of its own sedimentation effect, the cold air can be fully diffused in the height direction of the indoor environment, enabling the cold air to be fully diffused in each area of the indoor environment. In addition, under the action of the wall attachment effect, the cold air flowing towards the ceiling can flow along the ceiling, thereby enabling the cold air to be more efficiently diffused in the indoor environment.

[0066] Thus, when the air supply device is operating, through the cooperation of the first swing blade 210 and the second swing blade 310, the hot air in the entire area of the air outlet 101 can be pressed down, or the cold air in the entire area of the air outlet 101 can be lifted, so that the temperature of the indoor environment can reach the temperature set by the user more efficiently, thereby improving the temperature adjustment effect and comfort of the air supply device.

[0067] For the convenience of subsequent description, the first direction and the second direction are defined as two opposite directions in the height direction, and the first end wall 110 and the second end wall 120 are arranged in sequence along the first direction. Specifically, if the first end wall 110 is the top wall of the air outlet 101, the first direction is the downward direction; if the first end wall 110 is the bottom wall of the air outlet 101, the second direction is the upward direction.

[0068] Furthermore, in this embodiment, the connecting rod 320 is connected with a first transmission part 330, and the first swing blade 210 is connected with a second transmission part 220. In the initial position, the second swing blade 310 is in a horizontal state. When the second swing blade 310 swings towards the first direction, the first transmission part 330 is in a first state of being in transmission connection with the second transmission part 220 to drive the first swing blade 210 to swing towards the first direction. When the second swing blade 310 swings towards the second direction, the first transmission part 330 is in a second state of being disconnected from the second transmission part 220 to keep the first swing blade 210 in the initial position.

[0069] In this way, the linkage between the first swing blade 210 and the second swing blade 310 will not affect the full-angle swing of the second swing blade 310. By driving the first transmission part 330, the first swing blade 210 and the second swing blade 310 can be driven simultaneously. At the same time, the first swing blade 210 can also participate in the swing of half a process, which is beneficial to improving the swing effect of the air supply device. Among them, when the second swing blade 310 swings between the first limit position with the largest inclination angle towards the second direction and the second limit position with the largest inclination angle towards the first direction, the first swing blade 210 can intermittently swing synchronously with the second swing blade 310.

[0070] Specifically, starting from the first limit position, a complete swing process of the first transmission part 330 driving the second swing blade 310 is mainly divided into the following four processes in sequence:

[0071] The first process is that the first transmission part 330 drives the second swing blade 310 to swing towards the first direction, so that the second swing blade 310 swings from the first limit position to the horizontal state, corresponding to the state from Figures 6 to 4 At this time, the first transmission part 330 is in the second state, and there is no transmission cooperation between the first transmission part 330 and the second transmission part 220. The first swing blade 210 does not swing with the second swing blade 310, and the first swing blade 210 will maintain the initial position attached to the first end wall 110. At the same time, the abutting cooperation between the first swing blade 210 and the first end wall 110 will not interfere with the movement of the first transmission part 330;

[0072] The second process is that the first transmission part 330 drives the second swing blade 310 to continue swinging towards the first direction, so that the second swing blade 310 swings from the horizontal state to the second limit position, corresponding to the state from Figures 4 to 1 At this time, the first transmission part 330 is in the first state, and the first transmission part 330 is in transmission connection with the second transmission part 220. While driving the second swing blade 310 to swing, the first transmission part 330 will also drive the first swing blade 210 to swing through the second transmission part 220, so that the first swing blade 210 and the second swing blade 310 swing towards the first direction at the same time;

[0073] The third process is that the first transmission part 330 drives the second swing blade 310 to swing towards the second direction, so that the second swing blade 310 returns from the second limit position to the horizontal state. This process is carried out in the opposite direction to the second process, corresponding to the state from Figures 1 to 4 That is, the first transmission part 330 is still in the first state, and the first transmission part 330 is still in transmission connection with the second transmission part 220. The first transmission part 330 drives the first swing blade 210 and the second swing blade 310 to swing towards the second direction at the same time until the second swing blade 310 returns to the horizontal state, and the first swing blade 210 also abuts against the first end wall 110 correspondingly;

[0074] The fourth process is that the first transmission part 330 continues to drive the second swing blade 310 to swing in the second direction, so that the second swing blade 310 returns from the horizontal state to the first limit position. This process is carried out in the opposite direction to the third process, corresponding to the state from Figures 4 to 6 That is, the first transmission part 330 will be in the second state. The first transmission part 330 will disconnect the transmission connection with the second transmission part 220, so that the first transmission part 330 only drives the second swing blade 310 to swing alone, and will not drive the first swing blade 210 through the second transmission part 220. The first swing blade 210 will maintain its initial position against the first end wall 110 and will not swing together with the second swing blade 310.

[0075] Of course, in other embodiments, it may also be that the first transmission part 330 and the second transmission part 220 are driven by a weak acting force such as frictional force or elastic force. In the first state and the fourth state, for the second transmission part 220, this acting force can be offset by the abutting force of the first end wall 110 on the first swing blade 210, so that the first swing blade 210 can maintain its initial position.

[0076] Further, in this embodiment, please refer to Figures 7 to 9 And Figures 16 to 18 The first transmission part 330 is slidably connected to the housing 100 in the height direction. The first transmission part 330 is provided with a communicating thrust groove 331 and a relief groove 332. The thrust groove 331 and the relief groove 332 are sequentially distributed in the first direction. The relief groove 332 extends along the height direction, and the thrust groove 331 extends obliquely in the height direction. The second transmission part 220 is provided with a first sliding protrusion 221. In the first state, the first sliding protrusion 221 is slidably connected to the thrust groove 331. In the second state, the first sliding protrusion 221 is located in the relief groove 332. In this way, the intermittent transmission cooperation between the first transmission part 330 and the second transmission part 220 can be realized by switching the first sliding protrusion 221 between the thrust groove 331 and the relief groove 332.

[0077] For the convenience of subsequent description, please refer to Figure 18 Define the two groove side walls of the thrust groove 331 sequentially distributed in the first direction as the first groove side wall 3311, the second groove side wall 3312 and the groove end wall 3313 connecting the first groove side wall 3311 and the second groove side wall 3312.

[0078] In the first process, corresponding to the state from Figures 7 to 8In the state where the first transmission part 330 moves in the first direction, the first sliding convex part 221 is located in the avoidance groove 332, and the first sliding convex part 221 will slide along the extension direction of the avoidance groove 332. Therefore, there will be no movement interference between the first transmission part 330 and the second transmission part 220, nor will there be movement transmission;

[0079] In the second process, corresponding to the state where the first transmission part 330 continues to move in the first direction from Figures 8 to 9 In the state where the first transmission part 330 continues to move in the first direction, the first sliding convex part 221 switches to the pushing groove 331. The pushing groove 331 can push the first sliding convex part 221 through the first groove side wall 3311. When the groove end wall 3313 has a certain projected area in the height direction, the pushing groove 331 can also push the first sliding convex part 221 through the groove end wall 3313, thereby driving the first swing blade 210 to swing in the first direction together with the second swing blade 310;

[0080] In the third process, corresponding to the state where the first transmission part 330 moves in the second direction from Figures 9 to 8 In the state where the first transmission part 330 moves in the second direction, the first sliding convex part 221 is still located in the pushing groove 331. The pushing groove 331 can push the first sliding convex part 221 through the second groove side wall 3312, thereby driving the first swing blade 210 to swing in the second direction together with the second swing blade 310;

[0081] In the fourth process, corresponding to the state where the first transmission part 330 continues to move in the second direction from Figures 8 to 7 In the state where the first transmission part 330 continues to move in the second direction, the first sliding convex part 221 switches to the avoidance groove 332, thereby disconnecting the transmission connection between the first transmission part 330 and the second transmission part 220.

[0082] Of course, in other embodiments, it may also be that the intermittent transmission cooperation between the first transmission part 330 and the second transmission part 220 is realized through an incomplete gear mechanism.

[0083] Furthermore, in this embodiment, as Figures 10 to 13As shown, the second transmission part 220 is slidably connected to the housing 100 in the height direction. The housing 100 is further provided with a guide groove 400. The guide groove 400 includes a first groove section 410 and a second groove section 420 that are sequentially connected in the second direction. The first groove section 410 extends in the height direction. The second groove section 420 is provided with a guide inclined surface 421 connected to the first groove section 410. The direction of the guide inclined surface 421 is opposite to the direction in which the pushing groove 331 inclines relative to the first direction. In the second state, the first sliding convex part 221 abuts against the guide inclined surface 421. In the first state, the first sliding convex part 221 can slide along the guide inclined surface 421 and the first groove section 410. In this way, through the guiding action of the guide groove 400 on the first sliding convex part 221, the first sliding convex part 221 can be switched between the avoidance groove 332 and the pushing groove 331. Specifically:

[0084] As Figure 11 shown, when the second swing blade 310 is in the first extreme position, the first sliding convex part 221 abuts against the guide inclined surface 421 and is located in the avoidance groove 332 at a position relatively far from the pushing groove 331;

[0085] In the first process, the first transmission part 330 moves in the first direction, and the avoidance groove 332 and the pushing groove 331 also move in the first direction accordingly, so that the first sliding convex part 221 gradually approaches the pushing groove 331 until the second swing blade 310 is in the horizontal state. The first sliding convex part 221 is located at the communication position of the pushing groove 331 and the avoidance groove 332, and the first side wall 3321 abuts against the first sliding convex part 221;

[0086] In the second process, corresponding to the state from Figure 11 through Figures 12 to 13 , the first transmission part 330 continues to move in the first direction. The pushing groove 331 pushes the first sliding convex part 221 through the first side wall 3321, so that the first sliding convex part 221 slides into the first groove section 410 along the guide inclined surface 421, and drives the first sliding convex part 221 to slide in the first groove section 410 in the first direction, thereby driving the second transmission part 220 to move in the first direction. At the same time, the first sliding convex part 221 will also move in the pushing groove 331 in a direction away from the avoidance groove 332;

[0087] In the third process, the first transmission part 330 moves in the second direction. The pushing groove 331 will push the second sliding convex part 3322 through the second side wall 401, so that the first sliding convex part 221 slides in the first groove section 410 in the second direction along the pushing groove 331, thereby driving the second transmission part 220 to move in the second direction. At the same time, the first sliding convex part 221 will also move in the pushing groove 331 in the direction close to the avoiding groove 332 until the second swing blade 310 is in the horizontal state again, and the first sliding convex part 221 will also be in the previous state, that is, the first sliding convex part 221 abuts against the guiding inclined surface 421 and is located at the communication part of the pushing groove 331 and the avoiding groove 332;

[0088] In the fourth process, the first transmission part 330 continues to move in the second direction, and the first sliding convex part 221 enters the avoiding groove 332. The first transmission part 330 will be in the second state of disconnecting the transmission connection with the second transmission part 220. During the movement of the first transmission part 330, the first sliding convex part 221 will move in the first direction relative to the avoiding groove 332, that is, move in the position away from the pushing groove 331.

[0089] Of course, in other embodiments, it may also be that the first sliding convex part 221 is switched between the pushing groove 331 and the avoiding groove 332 by other means.

[0090] Further, in this embodiment, the groove width of the pushing groove 331 is adapted to the first sliding convex part 221, so that the pushing groove 331 can push the first sliding convex part 221 in different directions through the two groove side walls. The groove width of the avoiding groove 332 is designed with an appropriate allowance, so that the first sliding convex part 221 and the avoiding groove 332 are in clearance fit, ensuring that the first transmission part 330 disconnects the transmission connection with the second transmission part 220 in the second state. Further, as Figure 8 and Figure 9 shown, the end groove wall of the pushing groove 331 is arranged relative to the second side wall 401. In the second process, the pushing groove 331 first pushes the first sliding convex part 221 through the first groove side wall 3311, and at the same time the first sliding convex part 221 slides along the guiding inclined surface 421 until the end groove wall of the pushing groove 331 abuts against the first sliding convex part 221, and the first sliding convex part 221 will slide away from the guiding inclined surface 421 and enter the first groove section 410. After that, the first sliding convex part 221 is driven to slide in the first groove section 410 through the end groove wall. Of course, in other embodiments, it may also be that a part of the first groove side wall 3311 relative to the second side wall 401 pushes the first sliding convex part 221 to slide in the first groove section 410.

[0091] Further, in this embodiment, as Figure 3 and Figure 15As shown, the first swing blade 210 is successively and spacedly provided with a rotating shaft 211 and a first sliding groove 212 in the direction from the inside to the outside of the casing. The central axis of the rotating shaft 211 is parallel to the width direction of the air outlet 101, and the extending direction of the first sliding groove 212 is parallel to the extending direction of the first swing blade 210. The second transmission part 220 is convexly provided with a third sliding convex part 224 in the width direction of the air outlet 101, and the third sliding convex part 224 is slidably connected to the first sliding groove 212. In this way, when the second transmission part 220 moves in the height direction, the height of the third sliding convex part 224 will change. Restricted by the sliding fit between the third sliding convex part 224 and the first annular groove, the first swing blade 210 will rotate around the rotating shaft 211 to tilt to different degrees to adapt to the height change of the third sliding convex part 224. Thus, the second transmission part 220 can drive the first swing blade 210 to rotate. Specifically, the first sliding groove 212 is provided on the side of the first swing blade 210 away from the first end wall 110. The first swing blade 210 is formed with a first avoiding groove 213, and the second transmission part 220 passes through the first avoiding groove 213 so that the third sliding convex part 224 can be slidably connected to the first sliding groove 212. In this way, the surface of the first swing blade 210 facing the first end wall 110 is relatively flat and can abut more closely against the first end wall 110. At the same time, the first swing blade 210 can avoid the connecting rod 320 through the first avoiding groove 213. Of course, in other embodiments, the first swing blade 210 is formed with a shaft body on the outside, and the axis of the shaft body is also parallel to the width direction of the air outlet 101, that is, the horizontal direction. The first swing blade 210 is rotatably connected to the second transmission part 220 through the shaft body.

[0092] Further, in this embodiment, please also refer to Figure 4 、 Figure 5 and Figure 18, the first transmission part 330 is provided with a docking hole 334, the penetration direction of the docking hole 334 is parallel to the penetration direction of the air outlet 101, the connecting rod 320 is formed with a docking groove 321, the docking groove 321 opens outwards, and the first transmission part 330 and the connecting rod 320 are inserted into each other through the docking groove 321 and the docking hole 334. In this way, the first transmission part 330 can apply a force to the connecting rod 320 in the height direction to drive the connecting rod 320 to move in the height direction, thereby driving the plurality of second swing blades 310 to swing synchronously. Specifically, the second swing blade 310 is sequentially provided with two shaft bodies at intervals in the direction from the inside to the outside of the casing 100, the central axes of the two shaft bodies are both parallel to the width direction of the air outlet 101, the second swing blade 310 is rotatably connected to the casing 100 through the inner shaft body, and is drivingly connected to the connecting rod 320 through the outer shaft body. In this way, when the connecting rod 320 drives the second swing blade 310 to swing, the connecting rod 320 will shift slightly in the inner and outer directions, and the insertion fit of the docking groove 321 and the docking hole 334 reserves a margin for the shift of the connecting rod 320 in the inner and outer directions, so that the cooperation between the second transmission part 220 and the connecting rod 320 will not interfere with the cooperation between the connecting rod 320 and the second swing blade 310. Of course, in other embodiments, the first transmission part 330 and the connecting rod 320 can also be connected by a clamping method, and the connecting rod 320 and the second swing blade 310 can be connected by referring to the connection method between the second transmission part 220 and the first swing blade 210.

[0093] Further, in this embodiment, the air supply device further includes a driving device (not shown), and the driving device is drivingly connected to the first transmission part 330. In this way, through one driving device, the first swing blade 210 and the second swing blade 310 can be driven, which is beneficial to simplifying the structure of the air supply device and ensuring the cooperation of the movements of the first swing blade 210 and the second swing blade 310. Of course, in other embodiments, it may also be that the first transmission part 330 and the second transmission part 220 are respectively driven by different driving devices.

[0094] Further, in this embodiment, as Figure 14 and Figure 18As shown, the first transmission part 330 includes a rack part 333, the rack part 333 extends along the height direction, and is slidably connected to the housing 100 in the height direction. The output end of the driving device is connected to a driving gear (not shown), and the driving gear is meshed and transmitted to the rack part 333. In this way, after the driving device is started, the driving gear is driven to rotate, and the first transmission part 330 can be driven to move relative to the housing 100 in the height direction through the meshing transmission of the driving gear and the rack part 333. In addition, the rack part 333 can be moved at a relatively slow speed by controlling the transmission ratio of the driving gear and the rack part 333, so that the swing blades can swing smoothly. Of course, in other embodiments, the first transmission part 330 can also be driven to move by a linear motor.

[0095] Further, in this embodiment, please refer to Figure 14 , the first end wall 110 is provided with an escape opening, the first transmission part 330 and the second transmission part 220 are arranged in the escape opening, the driving device is arranged on the side of the first end wall 110 away from the first swing blade 210, the driving device is connected to the first transmission part 330 on this side, and the first transmission part 330 is connected to the second transmission part 220 on this side. In this way, the installation of the driving device and the arrangement of the first transmission part 330 and the second transmission part 220 can be facilitated, and the air outlet 101 will not be interfered with. Of course, in other embodiments, the driving device can also be installed on the side of the side wall of the air outlet 101 away from the air outlet 101, and each structure is also matched there.

[0096] Specifically, see Figure 14 , the first end wall 110 is provided with a first mounting portion 610 and a second mounting portion 620 in parallel on one side away from the first swing blade 210, and the guide groove 400 is formed in the second mounting portion 620. The first mounting portion 610 is formed with a second slide groove 612 and a receiving groove 611 which are connected to each other, and the driving device and the driving gear are received and installed in the receiving groove 611, and the rack portion 333 is slidably connected to the second slide groove 612, and the end of the rack portion 333 passes through the first mounting portion 610. It can be understood that the rack portion 333 is slidably connected to the second slide groove 612 along the height direction of the air outlet 101, so as to guide the second transmission portion 220 to move up and down through the second slide groove 612, and both ends of the second slide groove 612 are penetrated, respectively for the two ends of the rack portion 333 to pass through, so as to ensure that the rack portion 333 has sufficient length to cooperate with the driving gear. The driving device and the driving gear are received in the receiving groove 611 and can be protected by the first mounting portion 610 . The driving gear and the rack portion 333 are meshed and matched at the connection point between the receiving groove 611 and the second sliding groove 612 .

[0097] Further, in this embodiment, please refer to Figure 8 , Figure 9 and Figure 18 The two side walls of the avoidance groove 332 include a first side wall 3321 distributed downstream in the direction in which the push groove 331 is inclined relative to the avoidance groove 332, and the first side wall 3321 is provided with a second sliding protrusion 3322, and the second sliding protrusion 3322 is used for sliding connection with the first slot section 410. Specifically, the first transmission part 330 also includes a side connection part 335 connected to the side of the rack part 333, and the side connection part 335 is formed with a push groove 331 and an avoidance groove 332. In this embodiment, the movement of the side connection part 335 in the height direction can be guided by the sliding cooperation between the second sliding protrusion 3322 and the first slot section 410, so as to further improve the movement stability of the first transmission part 330.

[0098] Further, in this embodiment, please refer to Figure 18 , there are a plurality of second sliding protrusions 3322 distributed along the height direction, and at least one second sliding protrusion 3322 is slidably connected to the first slot section 410. In this way, the stable connection between the side connection portion 335 and the first slot section 410 can be ensured, so that the first slot section 410 can provide a guiding function for the first slot section 410 throughout the movement of the first transmission portion 330, so as to ensure the movement stability of the first transmission portion 330. At the same time, compared with the setting of the long strip-shaped sliding protrusion, the setting of the plurality of second sliding protrusions 3322 makes the friction between the second sliding protrusion 3322 and the first slot section 410 smaller, which can improve the sliding smoothness of the second sliding protrusion 3322 in the first slot section 410. Specifically, the side walls of the first slot section 410 and the second slot section 420 distributed downstream in the direction in which the push slot 331 is inclined relative to the avoidance slot 332 extend in sequence to form a second side wall 401 whose inner wall surface is on the same vertical line. In the fourth process, one of the second sliding protrusions 3322 slides into the position of the second slot section 420 and abuts against the second side wall 401, and at least one second sliding protrusion 3322 is still in the first slot section 410. Of course, in other ways, on the aforementioned side, the inner wall surface of the side wall of the second slot section 420 extends obliquely in a direction away from the other side wall and then extends in the height direction, as long as the side wall does not interfere with the second sliding protrusion 3322 sliding into the second slot section 420.

[0099] Further, in this embodiment, please refer to Figures 11 to 13 , Figure 16 and Figure 17The second transmission part 220 includes a main body 222 and an additional part 223 connected to each other. The main body 222 is connected to the first swing blade 210. The first sliding protrusion 221 is arranged on the additional part 223. The additional part 223 is inclined relative to the main body 222. Specifically, the first transmission part 330 realizes the sliding fit between the second transmission part 220 and the housing 100 through the main body 222. By arranging the first sliding protrusion 221 on the additional part 223, the transmission fit between the second transmission part 220 and the first transmission part 330 is realized. The inclined setting of the additional part 223 makes it possible for the second transmission part 220 and the above two to not interfere with each other, so that the first transmission part 330 and the second transmission part 220 are conveniently connected to the housing 100 in parallel. Based on the above structure, the main body 222 and the additional part 223 can be roughly rod-shaped structures, which is conducive to saving the material of the second transmission part 220. In addition, the side connection portion 335 is further provided with a second avoidance groove 336 on the side of the push groove 331, so that when the push groove 331 pushes the first sliding protrusion 221, the second avoidance groove 336 avoids the additional portion 223. Of course, in other embodiments, the second transmission portion 220 is provided with a plate-like structure, which cooperates with the housing 100 and the second transmission portion 220 in different areas.

[0100] Further, in this embodiment, please refer to Figures 11 to 13 , Figure 16 and Figure 17 The two side walls of the guide groove 400 include a second side wall 401 distributed downstream in the direction in which the push groove 331 is inclined relative to the avoidance groove 332, the main body 222 is slidably connected to the second side wall 401 at the outer side of the guide groove 400, and the additional part 223 is suspended at intervals on the side of the first side wall 3321 away from the second sliding protrusion 3322. In this way, the main body 222 is slidably connected to the second side wall 401 to achieve the sliding connection between the first transmission part 330 and the housing 100, so as to ensure the sliding stability of the first transmission part 330 relative to the housing 100, and the guide groove 400 can provide both the first sliding protrusion 221 for sliding cooperation and the second side wall 401 for the main body 222 for sliding cooperation, which is conducive to simplifying the structure of the housing 100. In the first state, the first sliding protrusion 221 is in the pushing groove 331, and the first sliding protrusion 221 and the second sliding protrusion 3322 cooperate with different positions of the first groove section 410 without interference; in the second state, since the additional part 223 is suspended on the first side wall 3321, the additional part 223 and the second sliding protrusion 3322 also do not interfere with each other.

[0101] In one embodiment, if Figure 16As shown, the additional part 223 and the main body part 222 are formed separately, and the additional part 223 is rotatably connected to the main body part 222. In this way, when the first sliding convex part 221 slides along the guiding inclined surface 421, the additional part 223 can rotate relative to the main body part 222 adaptively to ensure the smoothness of the sliding of the first sliding convex part 221. At the same time, the sliding of the first sliding convex part 221 along the guiding inclined surface 421 and the sliding of the main body part 222 along the second side wall 401 do not interfere with each other.

[0102] In an embodiment, as Figure 17 shown, the additional part 223 and the main body part 222 are integrally formed, and the additional part 223 can deform relative to the main body part 222. Similarly, this can enable the additional part 223 to rotate relative to the main body part 222 adaptively when the first sliding convex part 221 slides along the guiding inclined surface 421 to ensure the smoothness of the sliding of the first sliding convex part 221. At the same time, the sliding of the first sliding convex part 221 along the guiding inclined surface 421 and the sliding of the main body part 222 along the second side wall 401 do not interfere with each other. It should be noted that materials with high fatigue resistance should be selected to form the second transmission part 220, such as PP (Polypropylene), CFRP (Carbon Fiber Reinforced Polymer), or metal materials, etc.

[0103] Furthermore, when the additional part 223 and the main body part 222 are integrally formed, the guiding groove 400 may not be provided on the casing 100. Through the deformation of the additional part 223, the first sliding convex part 221 can be snapped into or out of the pushing groove 331 to achieve the switching between the first state and the second state. Of course, the guiding groove 400 can also be provided to slidably cooperate with the first sliding convex part 221 to ensure the cooperation stability of the first sliding convex part 221 with the pushing groove 331 and the avoiding groove 332.

[0104] It should be noted that when the housing 100 is configured on a heater, the first swing blade 210 is arranged corresponding to the top wall of the heater to assist the second swing blade 310 in pressing down the hot air of the heater. When the housing 100 is configured on the cabinet, at least one of the top wall and the bottom wall of the air outlet 101 is correspondingly provided with the first swing blade 210. That is, the first swing blade 210 may be arranged alone at the position corresponding to the top wall or the bottom wall of the air outlet 101, so that the cabinet only has one of the two functions of pressing down the hot air in the entire area of ​​the air outlet 101 and lifting the cold air in the entire area of ​​the air outlet 101. Alternatively, a first pendulum blade 210 is provided at the position corresponding to the top wall and the bottom wall of the air outlet 101, and the two ends of the connecting rod 320 are respectively connected to different first pendulum blades 210 in the same manner. The driving device can be provided corresponding to the end wall on one side. In this way, driven by the driving device, in the first half of the process when the second pendulum blade 310 swings upward from the lowest extreme position to the horizontal state, the upper first pendulum blade 210 and the second pendulum blade 310 swing synchronously until they abut against the top wall of the air outlet 101. Thereafter, in the second half of the process when the second pendulum blade 310 continues to swing upward from the horizontal state to the highest extreme position, the lower first pendulum blade 210 can swing upward with the second pendulum blade 310, and the process of placing the second pendulum blade 310 downward is carried out in reverse to the above process, which will not be repeated here.

[0105] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
