Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

If the specific posture changes, then the directional indications will also change accordingly.

[0044] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present utility model, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0045] The present utility model provides an air supply device, wherein the air supply device can be a warm air blower or an air conditioner. The specific product corresponding to the air conditioner can be a cabinet of a split air conditioner or a split air conditioner including a cabinet.

[0046] Please refer to Figures 1 to 6 , in an embodiment of the present utility model, the air supply device includes:

[0047] A housing 100, formed with an air outlet 101 extending along the height direction of the air supply device, and both ends of the air outlet 101 are respectively provided with a first end wall 110 and a second end wall 120;

[0048] A first swing blade 210, rotatably arranged in the air outlet 101 and corresponding to the first end wall 110. The first swing blade 210 has an initial position attached to the first end wall 110 and can swing towards the second end wall 120;

[0049] 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 other end wall and are connected by a connecting rod 320; and

[0050] A driving device (not shown), drivingly connected to the first swing blade 210 and the connecting rod 320.

[0051] 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 attached to 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.

[0052] As Figure 1 shown, when the first end wall 110 is the top wall of the air outlet 101, the driving device can drive the first swing blade 210 and the second swing blade 310 to rotate downward, so as to guide the hot air to blow out 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 rising effect, 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.

[0053] When the first end wall 110 is the bottom wall of the air outlet 101, the driving device can drive the first swing blade 210 and the second swing blade 310 to rotate upward, so as to guide the cold air to blow out 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, making the cold air flow towards the ceiling. Subsequently, under the trend of its own settling effect, the cold air can fully diffuse in the height direction of the indoor environment, so that the cold air can 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, so that the cold air can be more efficiently diffused in the indoor environment.

[0054] Therefore, 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 user-set temperature more efficiently, thereby improving the temperature adjustment effect and comfort of the air supply device.

[0055] Further, in this embodiment, when the first swing blade 210 is in the initial position, the driving device can drive the first swing blade 210 and a plurality of the second swing blades 310 to swing towards the second end wall 120 simultaneously, and can separately drive the plurality of the second swing blades 310 to swing away from the second end wall 120. In this way, the linkage between the first swing blade 210 and the second swing blade 310 will not affect the full-angle air swing of the second swing blade 310, so that the present utility model can drive the first swing blade 210 and the second swing blade 310 through the same driving device. At the same time, the first swing blade 210 can also participate in the air swing in half of the process, which is beneficial to improving the air swing effect of the air supply device. Among them, when the second swing blade 310 swings between the first extreme position with the largest inclination angle towards the first end wall 110 and the second extreme position with the largest inclination angle towards the second end wall 120, the first swing blade 210 can intermittently swing synchronously with the second swing blade 310. Specifically, when the second swing blade 310 swings from the first extreme position to the horizontal state, the first swing blade 210 will remain in the initial position attached to the first end wall 110. When the second swing blade 310 swings from the horizontal state to the second extreme position, the driving device will drive the first swing blade 210 and the second swing blade 310 to swing simultaneously. When the second swing blade 310 returns from the second extreme position to the first extreme position, the first swing blade 210 will also return to the initial position until the second swing blade 310 is in the horizontal state, and the first swing blade 210 will also be attached and abutted against the first end wall 110. After that, the second swing blade 310 will continue to swing towards the second extreme position alone, and the first swing blade 210 will remain in the initial position attached to the first end wall 110. Of course, in other embodiments, it may also be that the first swing blade 210 and the second swing blade 310 are driven by different driving devices respectively.

[0056] Further, in this embodiment, as Figures 7 to 9As shown, the connecting rod 320 is connected to a first transmission part 330, the first swing blade 210 is connected to a second transmission part 220, the driving device is drivingly connected to the first transmission part 330, the first transmission part 330 is drivingly connected to the second transmission part 220, and when the first swing blade 210 is driven to swing towards the direction of the first end wall 110, it abuts against the first end wall 110. The abutment of the first swing blade 210 during movement means that the acting force of the first transmission part 330 driving the first swing blade 210 cannot overcome the resistance of the first end wall 110 to the first swing blade 210, so that the first swing blade 210 can be maintained at the initial position. At the same time, when this acting force acts on the first transmission part 330 in the opposite direction, it will not interfere with the first transmission part 330 driving the second swing blade 310 to swing. Specifically, this acting force can be an elastic force or a frictional force. Of course, in other embodiments, it can also be that the driving connection between the first transmission part 330 and the second transmission part 220 is disconnected, so that the driving device only drives the second swing blade 310 and does not drive the first swing blade 210.

[0057] Further, in this embodiment, as Figures 7 to 9 shown, the air supply device further includes an elastic member 500. Two ends of the elastic member 500 are respectively fixed to the first transmission part 330 and the second transmission part 220. When the second swing blade 310 is in a horizontal state, the elastic member 500 is in a natural state. When the first swing blade 210 is in the initial position, the second swing blade 310 is correspondingly in a horizontal state, and the elastic member 500 is correspondingly in the Figure 8 natural state shown. Please refer to Figure 7 and Figure 8 together. When the first transmission part 330 drives the second swing blade 310 to swing towards the first limit position, it will drive the elastic member 500 to undergo elastic deformation, and the second transmission part 220 will also be subjected to the elastic force of the elastic member 500. The acting direction of this elastic force is opposite to the abutting force of the first end wall 110 on the first swing blade 210, and the two cancel each other out, so that the first swing blade 210 is maintained at the initial position in contact with the first end wall 110. Please refer to Figure 8 and Figure 9, when the first transmission part 330 drives the second swing blade 310 to swing towards the second extreme position, it can act on the elastic part 500, making the elastic part 500 tend to have elastic deformation. The acting force of the first transmission part 330 can be transmitted to the first swing blade 210 through the elastic part 500 and the second transmission part 220 in sequence. Since the first swing blade 210 is not pushed on the side away from the end wall, this acting force can drive the first swing blade 210 to swing in the same direction as the second swing blade 310. At the same time, the elastic part 500 will also be maintained in the natural state or in a state of appropriate deformation. When the second swing blade 310 moves to the second extreme position and the driving device runs in the reverse direction to drive the second swing blade 310 to reset to the horizontal state, it can also drive the first swing blade 210 to return to the initial position through the elastic part 500. Of course, in other embodiments, it can also be that the first transmission part 330 can also drive the second transmission part 220 through friction.

[0058] Further, in this embodiment, as Figures 7 to 9 shown, the elastic part 500 is sleeved outside the second transmission part 220. The first transmission part 330 is connected with a sleeve part 331. The central axis of the sleeve part 331 is parallel to the height direction. The sleeve part 331 is movably sleeved on the second transmission part 220. The two ends of the elastic part 500 are respectively fixed on the sleeve part 331 and the second transmission part 220. It can be understood that the first transmission part 330 applies an acting force to the connecting rod 320 in the height direction, thereby driving the sleeve part 331 to slide along the second transmission part 220 in the height direction. In this way, the sleeve part 331 can apply an acting force in the height direction to the second transmission part 220 through the elastic part 500 to drive the second transmission part 220 to move in the same way as the first transmission part 330, so as to drive the first swing blade 210 to rotate. In this embodiment, the coaxiality of the sleeve part 331, the elastic part 500 and the second transmission part 220 is good, so that the sleeve part 331 can apply a stable acting force to the second transmission part 220 through the elastic part 500, which is beneficial to ensuring the cooperation stability and transmission stability between the first transmission part 330 and the second transmission part 220. Among them, the elastic part 500 can be a spring, an elastic rubber sleeve, an elastic silica gel sleeve, etc. Of course, in other embodiments, the axis of the elastic part 500 is distributed along the width direction of the air outlet 101. The first transmission part 330 and the second transmission part 220 extend at intervals along the height direction and can move relative to the machine shell 100 in this direction. In this way, the two ends of the elastic part 500 are respectively fixedly connected to the first transmission part 330 and the second transmission part 220, and the transmission cooperation between the first transmission part 330 and the second transmission part 220 can also be realized.

[0059] Further, in this embodiment, please refer to Figure 3 , Figure 10 and Figure 11, the first swing blade 210 is sequentially 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 100. 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 protrudes with a sliding convex part 221 in the width direction of the air outlet 101, and the sliding convex part 221 is slidably connected to the first sliding groove 212. Thus, when the second transmission part 220 moves in the height direction, the height of the sliding convex part 221 will change. Restricted by the sliding fit between the sliding convex part 221 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 sliding convex part 221. 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 an avoidance groove 213, and the second transmission part 220 passes through the avoidance groove 213 so that the sliding convex part 221 can be slidably connected to the first sliding groove 212. Thus, the surface of the first swing blade 210 facing the first end wall 110 is relatively flat and can abut against the first end wall 110 more closely. At the same time, the first swing blade 210 can avoid the connecting rod 320 through the avoidance groove 213. Of course, in other embodiments, the first swing blade 210 forms 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.

[0060] Further, in this embodiment, please refer to Figure 1 and Figure 12, the first transmission part 330 is provided with a docking hole 334 which runs through in the horizontal direction. The connecting rod 320 is formed with a docking groove 321. One side of the docking groove 321 in the horizontal direction is provided with a docking port. The docking groove 321 is inserted into the docking hole 334 from the docking port. 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 a plurality of second swing blades 310 to swing synchronously. Specifically, the second swing blades 310 are sequentially provided with two shaft bodies at intervals in the direction from the inside to the outside of the housing 100. The central axes of the two shaft bodies are both parallel to the width direction of the air outlet 101. The second swing blades 310 are rotatably connected to the housing 100 through the inner shaft body and are drivingly connected to the connecting rod 320 through the outer shaft body. In this way, when the connecting rod 320 drives the second swing blades 310 to swing, the connecting rod 320 will shift slightly in the inner and outer directions. 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 blades 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 blades 310 can be connected by referring to the connection method between the second transmission part 220 and the first swing blades 210.

[0061] Further, in this embodiment, please refer to Figure 2 and Figures 7 to 9 , the elastic member 500 is located on the side of the sleeve part 331 close to the second end wall 120. In this way, when the second swing blade 310 swings independently, the sleeve part 331 will pull the elastic member 500 to stretch. Compared with compressing the elastic member 500, when the elastic range of the elastic member 500 is guaranteed, the moving process of the sleeve part 331 will not be restricted by the space occupied by the elastic member 500 itself, so that the elastic member 500 can meet the requirements of the moving process of the sleeve part 331 to ensure the air-swinging effect of the second swing blade 310. Of course, in other embodiments, on the premise of meeting the moving process of the sleeve part 331, the elastic member 500 can also be arranged on the other side of the sleeve part 331. When the second swing blade 310 swings independently, the elastic member 500 will be compressed.

[0062] Further, in this embodiment, please refer to Figures 7 to 9 , Figure 11 and Figure 12, snap rings 332 are provided on the outer circumferences of both the sleeve portion 331 and the first transmission portion 330, and the end of the elastic member 500 is snap-fitted to the corresponding snap ring 332. Specifically, when the elastic member 500 is a spring, by snap-fitting the snap projection between adjacent spring layers at the corresponding ends of the spring, the two ends of the elastic member 500 are respectively fixed to the sleeve portion 331 and the first transmission portion 330. Of course, in other embodiments, the elastic member 500 can also be fixed by means of embedding or gluing.

[0063] Further, in this embodiment, please refer to Figure 12 and Figure 13 , the first transmission portion 330 includes a rack portion 333, the rack portion 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 drivingly connected to a driving gear 400, and the driving gear 400 meshes with and drives the rack portion 333. In this way, after the driving device is started, it drives the driving gear 400 to rotate, and then through the meshing drive between the driving gear 400 and the rack portion 333, the first transmission portion 330 can be driven to move relative to the housing 100 in the height direction. Moreover, by controlling the transmission ratio between the driving gear 400 and the rack portion 333, the rack portion 333 can move at a relatively gentle speed, so that the swing blade swings smoothly. Of course, in other embodiments, it can also be that the first transmission portion 330 is driven to move by a linear motor.

[0064] Further, in this embodiment, the driving device is provided on the side of the first end wall 110 away from the first swing blade 210, and the first end wall 110 is provided with an avoidance opening, and the first transmission portion 330 and the second transmission portion 220 pass through the avoidance opening. In this way, it is convenient for the installation of the driving device and the arrangement of the first transmission portion 330 and the second transmission portion 220.
