DETAILED DESCRIPTION

[0043] In order to make the above objectives, features and advantages of the present application more apparent, clear and complete, the technical solutions in the embodiments of the present application are described in detail. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] The air guide device provided by the embodiments of the present application comprises: an air guide cylinder 120, which is arranged at an air outlet and can be switched between a first state and a second state; the air guide cylinder 120 covers the air outlet in the first state, and the air guide cylinder 120 extends outward from the air outlet in the second state to guide the air inside the air conditioner outward; wherein the air guide cylinder 120 is switched from the first state to the second state through a rotating extension action, and is switched from the second state to the first state through a rotating retraction action.

[0045] Specifically, as shown in FIG. 1, the air guide cylinder 120 is arranged at the air outlet 410, and the air guide cylinder is switched between the first state and the second state; when the air guide cylinder 120 is switched to the first state, the air guide cylinder 120 covers the air outlet 410 to prevent dust in the air from entering the inside of the air conditioner and affecting the use effect of the air conditioner; at the same time, the air guide cylinder 120 is accommodated at the air outlet 410, which reduces the occupied space and makes the air conditioner more beautiful; when the air guide cylinder 120 is switched to the second state, as shown in FIG. 2, the air guide cylinder 120 extends outward from the air outlet to guide the air inside the air conditioner outward, thereby improving the air quality indoors. Figure 1 Figure 2

[0046] ​​Specifically, the air guiding device also includes: a sweeping connecting rod 110, which is connected to the air guiding duct 120; a rotary drive device 200, which is connected to the sweeping connecting rod 110 and is used to drive the sweeping connecting rod 110 to swing back and forth along its own axis; and a rotary device 230, which is arranged adjacent to the air guiding duct 120 and is connected to the sweeping connecting rod 110. The sweeping connecting rod 110 swings back and forth, driving the rotary device 230 to rotate, thereby driving the air guiding duct 110 to rotate.

[0047] Specifically, as shown in the appendix Figure 4 As shown, the air guide duct 120 is fixed on the sweeping connecting rod 110. The rotary drive device 200 is located at the end of the sweeping connecting rod 110, driving the sweeping connecting rod 110 to swing back and forth along its own axis, thereby causing the air guide duct 120 to swing. When the sweeping connecting rod 110 swings back and forth, it drives the rotary device 230 to rotate, causing the air guide duct 120 to rotate. During the process of the air guide duct 120 switching from the first state to the second state, the air outlet 410 of the air guide duct 120 extends outward, thereby exhausting the air inside the air conditioner to the outside.

[0048] Specifically, the rotary drive device 200 includes: a rotary motor 210, which is provided with a first gear 211; and a threaded part 220, which is sleeved on the end of the sweeping connecting rod 110. The first gear 211 and the threaded part 220 mesh with each other, driving the sweeping connecting rod 110 to swing back and forth along its own axis, thereby causing the air guide tube 120 to swing.

[0049] As attached Figure 5 As shown, the rotary motor 210 drives the first gear 211 to rotate. The first gear 211 meshes with the threaded component 220, causing the sweeping connecting rod 110 to move along its axial direction. The rotary motor 210 controls the rotation direction of the first gear 211 by rotating forward and backward, thereby realizing the reciprocating oscillation of the sweeping connecting rod 110. This transmission method, where the rotary motor 210 drives the first gear 211 to mesh with the threaded component 230, makes the rotation speed of the first gear 211 more stable and the transmission accuracy higher. At the same time, the gear meshing structure is relatively simple, resulting in higher efficiency and lower production costs during assembly.

[0050] Specifically, the rotating device 230 includes: a mounting part 231, which is disposed on the sweeping connecting rod 110. The sweeping connecting rod 110 is connected to the air guide tube 120 through the mounting part 231. A fixing member 421 is disposed at the bottom of the sweeping connecting rod 110. The sweeping connecting rod 110 and the fixing member 111 are connected to each other. The sweeping connecting rod 110 and the fixing member 111 can slide relative to each other so as to avoid position interference when the air guide tube 120 rotates.

[0051] As attached Figure 6As shown, the mounting portion 231 is arranged on the air sweeping link 110, and specifically, the mounting portion 231 is a circular through hole, as shown in FIG. 2. Figure 7 As shown, the mounting portion 231 is connected with the air guide cylinder 120 through a fastener, which is convenient for mounting and dismounting, and the fastener is cheap and easy to obtain, thereby reducing the production cost. The bottom of the air sweeping link 110 is provided with a fixing member 111, and the fixing member 111 is provided with a waist-shaped hole, as shown in FIG. 2. Figure 8 As shown, when the air guide cylinder 120 is switched from the first state to the second state, the air guide cylinder 120 rotates around the rotating shaft 101 as the rotating center, and the air sweeping bracket 110 is provided with a latch that is embedded in the waist-shaped hole of the fixing member 111. When the air guide cylinder 120 rotates, the latch of the air sweeping bracket 110 reciprocally slides in the waist-shaped hole of the fixing member 111, thereby avoiding position interference when the air guide cylinder 120 rotates, and causing the air guide cylinder 120 to rotate unsmoothly. The sliding of the latch in the waist-shaped hole has a relatively simple structure, is convenient for mounting, does not need to increase an additional motor for driving, has a lower cost, and has a more compact structure and occupies a smaller space.

[0052] For example, the air guide device is connected with the air conditioner through an air guide bracket 420. The air guide bracket 420 is horizontally arranged at the air outlet 410. The air guide cylinder 120 is provided with a rotating shaft 101. The air guide bracket 420 is provided with a mounting member 421. The rotating shaft 101 is connected with the air guide bracket 420 through the mounting member 421, and rotates around the rotating shaft 101 as the rotating center in the case of rotating the air guide cylinder 120.

[0053] As shown in FIG. 2, the air guide device is connected with the air conditioner through the air guide bracket 420. Figure 3 As shown, the rotating shaft 101 is arranged in the interior of the air guide cylinder 120, and the rotating shaft 101 is connected with the air guide bracket 420, as shown in FIG. 2. Figure 3 As shown, the rotating shaft 101 penetrates through the through hole of the mounting member 421 to fix the air guide cylinder 120 on the air guide bracket 420. When the air guide cylinder 120 is switched between the first state and the second state, the air guide cylinder 120 rotates around the rotating shaft 101 as the rotating center, so that the air guide cylinder 120 does not deviate from the original position after stopping rotating and does not interfere with other components. Meanwhile, the rotating shaft 101 plays a role in fixing the air guide cylinder 120, preventing the air guide cylinder 120 from being separated from the air outlet 410, and making the air conditioner more secure during operation, as shown in FIG. 2. Figure 6 As shown, the air guide device is fixed on the air guide bracket 420, thereby being convenient for fixing the air guide device at the air outlet 410 of the air conditioner.

[0054] For example, the air guide device further includes: an air sweeping link 110, which is connected with the air guide cylinder 120; and a telescopic driving device 300, which is connected with the air sweeping link 110 and is used to drive the air sweeping link 110 to rotate along the axis line thereof, so that the air guide cylinder 120 is extended or retracted relative to the air outlet 410 by rotating around the air sweeping link 110.

[0055] As attached Figure 5 As shown, the telescopic drive device 300 and the rotary drive device 200 are arranged adjacent to each other. The telescopic motor 310 drives the third gear 330 to rotate. The second gear 320 is sleeved on the end of the sweeping connecting rod 110, and there is a gap between it and the threaded part 220 to avoid positional interference between the second gear 320 and the first gear 211. The third gear 330 drives the second gear 320 to rotate, thereby causing the sweeping connecting rod 110 to rotate around its own axis. The air guide tube 120 is fixed on the sweeping connecting rod 110. When the sweeping connecting rod 110 rotates around its own axis, it causes the air guide tube 120 to swing. The telescopic motor 310 controls the rotation direction of the third gear 330 by the forward and reverse rotation of the telescopic motor, driving the sweeping connecting rod 110 to reciprocate around its own axis, thereby realizing the extension or retraction of the air guide tube 120 relative to the air outlet.

[0056] For example, the telescopic drive device 300 further includes: a transition gear 340, which is disposed between the second gear 320 and the third gear 330. The transition gear 340 meshes with the second gear 320 and the third gear 330 respectively, so that the third gear 330 drives the second gear 320.

[0057] For details, see attached. Figure 5 As shown, the transition gear 340 is located between the second gear 320 and the third gear 330 to prevent positional interference between the first gear 311 and the third gear 330, which would affect the rotation of the gears. The telescopic motor 310 drives the third gear 330 to rotate, and the third gear 330 meshes with the transition gear 340, causing the transition gear 340 to rotate. The second gear 320 meshes with the transition gear 340, thereby causing the sweeping connecting rod 110 to rotate along with the second gear 320.

[0058] For example, the air guiding device is provided in two sets, and the air guiding tubes 120 of the two sets of air guiding devices rotate in opposite directions so as to avoid interference when the air guiding tubes 120 rotate.

[0059] As attached Figure 8 As shown, the air guiding device has two sets, each set having three air guide tubes 120. If only one set of air guide tubes 120 is located at the air outlet 410, the sweeping connecting rod 110 is prone to breakage. To enhance the strength of the sweeping connecting rod 110, two sets of air guiding devices are provided at the air outlet 410. Furthermore, the two sets of air guiding devices have multiple air guide tubes 120, increasing the airflow of the air conditioner, as shown in the attached diagram. Figure 7 As shown, the air guide tubes 120 of the two sets of air guide devices rotate in opposite directions, which can sweep air on the left and right sides at the same time, resulting in better air delivery.

[0060] The application further provides an air conditioner, which comprises an air conditioner body 400, an air outlet 410 arranged on the air conditioner body 100, and a wind guide device 100 arranged at the air outlet 410.

[0061] As shown in the accompanying drawings, Figure 2 The air conditioner specifically comprises the air conditioner body 400, the air outlet 410 and the wind guide device 100, wherein the air conditioner of the application comprises the wind guide device of any of the technical solutions of the application, thus having all the beneficial effects of the wind guide device of any of the technical solutions of the application, which will not be described herein again.

[0062] As shown in the accompanying drawings, Figure 9 to the accompanying drawings, Figure 12 The movement process of the air guide cylinder 120 from the first state to the second state is shown in the accompanying drawings, so as to guide the air inside the air conditioner to the outside.

[0063] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, and not to limit them; although the application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
