[0050] This utility model proposes an air outlet device 100.

[0051] Please see Figures 1 to 6 In one embodiment of this utility model, the air outlet device 100 includes a frame 1, swing blades 2, and mounting components 3. The frame 1 has an overall rectangular shape and extends along the height direction (first direction). An air outlet channel 11 is provided on the frame 1. Figure 3 As shown, the air outlet channel 11 is arranged through the thickness direction (second direction) of the frame 1, and the two ends are respectively provided with an air inlet 112a and an air outlet 111a. The swing blade 2 is installed into the air outlet channel 11 from one side of the air inlet 111a and is rotatably arranged in the air outlet channel 11 to change the air outlet direction of the air outlet channel 11. The swing blade 2 has a coaxial first rotating shaft 21 and a second rotating shaft 22 at both ends along the first direction. A plate-like structure for swinging is provided between the first rotating shaft 21 and the second rotating shaft 22. The mounting assembly 3 includes a first mounting base 31 and a second mounting base 32 that are detachably connected to the frame 1. The first mounting base 31 has a first shaft hole 311, and the first rotating shaft 21 of the swing blade 2 is rotatably disposed in the first shaft hole 311. The second mounting base 32 has a second shaft hole 321, and the second rotating shaft 22 of the swing blade 2 is rotatably disposed in the second shaft hole 321. The first shaft hole 311 and the second shaft hole 321 both extend along the first direction and are arranged with their axial directions overlapping.

[0052] It should be noted that the first mounting base 31 and the second mounting base 32 can be connected to the frame 1 using the following methods, including but not limited to: threaded connection, pin connection, snap ring (clip) connection, quick-connect connection, fastener connection, etc., as long as a detachable connection between the first mounting base 31 and the second mounting base 32 and the frame 1 can be achieved. These methods will not be elaborated further here. It is understood that by setting the first mounting base 31 and the second mounting base 32, direct contact between the swing blade 2 and the frame 1 is avoided, preventing abnormal noise caused by the rotational friction between the frame 1 and the swing blade 2 during use of the air outlet device 100. Furthermore, the first mounting base 31 and the second mounting base 32 can provide stable support for the swing blade 2, ensuring smooth rotation of the swing blade 2 and effectively reducing friction and vibration sources, thereby reducing vibration of the frame 1 and reducing noise.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the first mounting base 31 and the second mounting base 32 are disposed at opposite ends of the frame 1 along a first direction, the first direction being the height direction of the frame 1. The swing blade 2 extends along the height direction of the frame 1. The first rotating shaft 21 and the second rotating shaft 22 are disposed on the swing blade 2 and their rotation axes coincide along the first direction. The first mounting base 31 is disposed at the upper end of the swing blade 2. The first rotating shaft 21 is rotatably disposed in the first shaft hole 311 of the first mounting base 31. The second mounting base 32 is disposed at the lower end of the swing blade 2. The second rotating shaft 22 is rotatably disposed in the second shaft hole 321 of the second mounting base 32. When the swing blade 2 rotates and swings around the first rotating shaft 21 and the second rotating shaft 22, the airflow in the air outlet channel 11 can be controlled to swing and exit in the horizontal direction.

[0054] In another embodiment of this utility model, the air outlet device 100 is placed horizontally during use, with the first direction being horizontal. Both the frame 1 and the swing blades 2 extend horizontally. A first mounting base 31 is located on the left side of the swing blades 2 and rotatably connected to a first rotating shaft 21. A second mounting base 32 is located on the right side of the swing blades 2 and rotatably connected to a second rotating shaft 22. When the swing blades 2 rotate and swing around the first rotating shaft 21 and the second rotating shaft 22, the airflow in the air outlet channel 11 can be controlled to swing and exit in the vertical direction. It is understood that setting the first direction to the height direction of the frame 1 or the horizontal direction allows the air outlet device 100 to adapt to air outlet requirements in different directions, thus improving its adaptability.

[0055] It should be noted that in the above embodiments, regardless of whether the first direction is the height direction or the horizontal direction, both the frame 1 and the swing blade 2 extend along the first direction. However, in some other embodiments of this utility model, the frame 1 may extend along the height direction while the swing blade 2 extends along the horizontal direction, or vice versa. The specific extension is not limited. The first mounting base 31 and the second mounting base 32 are respectively installed at both ends of the swing blade 2. The structure of the frame 1 can be configured to create an air outlet channel 11 according to the installation direction of the swing blade 2, while the first mounting base 31 and the second mounting base 32 are flexibly installed on the frame 1 corresponding to the swing blade 2 to adapt to different air outlet scenarios.

[0056] like Figures 1 to 3 As shown, in one embodiment of this utility model, the upper end of the frame 1 is provided with a first mounting groove 12 that is open to one side. The shape of the first mounting groove 12 matches the shape of the first mounting base 31. The side wall of the first mounting groove 12 near the air outlet channel 11 is provided with a first through hole 13 that communicates with the air outlet channel 11. The first mounting base 31 is detachably installed into the first mounting groove 12 through the groove, so that the first shaft hole 311 is aligned with the first through hole 13. The first rotating shaft 21 of the swing blade 2 in the air outlet channel 11 passes through the first through hole 13 and is inserted into the first shaft hole 311.

[0057] Understandably, the first mounting slot 12 is used to limit the installation of the first mounting base 31, which can improve the stability of the connection between the first mounting base 31 and the swing blade 2. In addition, the first mounting base 31 and the first mounting slot 12 can be detachably connected by screws, pins, clips, dowels, etc., without limitation, and can be selected according to needs. The detachable connection between the first mounting base 31 and the frame 1 is beneficial to improving the disassembly and assembly efficiency of the air outlet device 100, and facilitates assembly and component replacement and maintenance.

[0058] like Figure 3 As shown, in one embodiment of this utility model, the air outlet duct 11 has a first air passage 111 and a second air passage 112. One of the first air passage 111 and the second air passage 112 is configured as an air inlet 112a, and the other is configured as an air outlet 111a. The swing blade 2 can be installed into the air outlet duct 11 from the first air passage 111. The slot of the first mounting base 31 is oriented towards the first air passage 111. (Refer to reference...) Figure 1 and Figure 2 Both the first mounting slot 12 and the first air outlet 111 are arranged along the second direction, so that the first mounting base 31 and the swing blade 2 can be installed from the same side of the frame 1, which helps to reduce assembly difficulty and improve production efficiency. The swing blade 2 can also be installed into the air outlet duct 11 from the second air outlet 112, and its structure is not specifically limited here.

[0059] In one embodiment of this utility model, the wall of the first through hole 13 is provided with a first clearance notch that runs through the axis of the first rotating shaft 21. The first clearance notch is located on the same side as the groove of the first mounting groove 12 and the first air outlet 111. During assembly, the first mounting base 31 can be inserted into the first mounting groove 12 first, and then the swing blade 2 can be inserted into the air outlet channel 11 from one side of the frame 1. The first rotating shaft 21 can be inserted through the first through hole 13 into the first shaft hole 311. Alternatively, the first rotating shaft 21 of the swing blade 2 can be inserted into the first shaft hole 311 of the first mounting base 31 first, and then the swing blade 2 and the first mounting base 31 can be installed together on the frame 1. The first rotating shaft 21 can be inserted into the first through hole 13 through the first clearance notch. As can be seen from the above, by providing a first clearance notch that connects to the first through hole 13, the assembly difficulty of the air outlet device 100 can be further reduced, and the installation method is also more diversified.

[0060] In another embodiment of this utility model, the air outlet channel 11 has a first air passage 111, and the swing blade 2 can be installed into the air outlet channel 11 from the first air passage 111. The slot of the first mounting base 31 is arranged facing the first air passage 111, and the hole wall of the first through hole 13 is provided with a first clearance notch that runs through the axis of the first rotating shaft 21. The first clearance notch is arranged on the same side as the slot of the first mounting groove 12 and the first air passage 111, so that the first rotating shaft 21 can be inserted into the first through hole 13 from the first clearance notch during installation. The specific details will not be elaborated further.

[0061] like Figure 3 and Figure 5 As shown, in one embodiment of this utility model, a first hook 312 is provided on one side of the first mounting base 31, and a first slot 121 is provided on the groove wall of the first mounting groove 12 corresponding to the first hook 312. When the first mounting base 31 is inserted into the first mounting groove 12, the first hook 312 engages in the first slot 121, making the first mounting base 31 detachably connected to the frame 1. Alternatively, a slot may be provided on the first mounting base 31, and a corresponding hook may be provided on the groove wall of the first mounting groove 12, so that the first mounting base 31 can engage in the first mounting groove 12. The specific details are not limited.

[0062] In one embodiment of this utility model, the first mounting base 31 is further provided with a guide portion 313, and the groove wall of the first mounting groove 12 is further provided with a guide hole 122 adapted to the guide portion 313. The guide portion 313 is inserted into the guide hole 122 to guide and position the first mounting base 31, so that the first hook 312 is accurately engaged in the first slot 121, and the first mounting base 31 is prevented from being displaced relative to the frame 1, ensuring the fit between the first rotating shaft 21 and the first shaft hole 311, and avoiding abnormal noise caused by increased friction due to the offset of the first mounting base 31.

[0063] like Figure 5As shown, in one embodiment of this utility model, two first hooks 312 and two guide portions 313 are provided on the same side of the first mounting base 31. The first hooks 312 and guide portions 313 extend in a second direction. The two first hooks 312 are respectively located at both ends of the first mounting base 31, and the two columnar guide portions 313 are spaced apart between the two first hooks 312. Correspondingly, the groove walls on opposite sides of the first mounting groove 12 are respectively provided with first slots 121, and two guide holes 122 are provided between the two first slots 121 to correspond to the first hooks 312 and guide portions 313 respectively. It can be understood that by providing two hooks and two guide portions 313, the first mounting base 31 can be quickly inserted and the position of the first mounting base 31 on the frame 1 can be ensured.

[0064] It should be noted that in some other embodiments of this utility model, the positions of the first hook 312 and the second hook 324 may be located on different sides of the first mounting base 31, so as to achieve positioning and installation, and the number of the first hook 312 and the second hook 324 is not specifically limited.

[0065] Please refer to Figure 2 , Figure 3 and Figure 6 In one embodiment of this utility model, the air outlet duct 11 is arranged along a second direction, and the second mounting base 32 has a first side and a second side opposite to each other along the second direction. The first side is arranged near the air inlet 112a of the air outlet duct 11, and the second side is arranged near the air outlet 111a of the air outlet duct 11. Figure 6 The second shaft hole 321 has a mounting opening 322 on its wall. The first side of the second mounting base 32 is the side with the mounting opening 322, and the second side is the side with the second hook 324. The opening of the mounting opening 322 faces the first side. During assembly, the second mounting base 32 can be fixed to the frame 1 first, and then the swing blade 2 can be inserted into the air outlet 11 through the first air inlet 111. At this time, the mounting opening 322 of the second mounting base 32 faces outward, and the second rotating shaft 22 of the swing blade 2 can be inserted into the second shaft hole 321 through the mounting opening 322.

[0066] It should be noted that the first side of the second mounting base 32 is provided with an elastic part 325, and two elastic parts 325 are provided on the outward side of each second shaft hole 321. An installation opening 322 is formed between the two elastic parts 325. The width of the installation opening 322 is smaller than the diameter of the second rotating shaft 22. When the second rotating shaft 22 is pressed in, the second rotating shaft 22 squeezes the two elastic parts 325 to cause elastic deformation. After the second rotating shaft 22 is inserted into the second shaft hole 321, the elastic part 325 rebounds to limit the second rotating shaft 22 to be located in the second shaft hole 321.

[0067] In one embodiment of this utility model, such as Figure 6As shown, the second mounting base 32 is also provided with a clearance groove 323. The opening of the clearance groove 323 faces the second side of the second mounting base 32, so that the opening direction of the mounting port 322 is set in the opposite direction to the opening of the clearance groove 323. The air outlet device 100 also includes a drive assembly 4. The drive assembly 4 is located at the bottom of the frame 1 and is drivenly connected to the swing blade 2 to drive the swing blade 2 to swing. The clearance groove 323 is used for the installation of the drive assembly 4. The specific structure is described below.

[0068] like Figure 3 As shown, in one embodiment of this utility model, the frame 1 is further provided with a second mounting groove 14 that is open to one side. The second mounting groove 14 has a second through hole 15 on its side wall near the air outlet channel 11. The second mounting base 32 is detachably inserted into the second mounting groove 14 through the groove, such that the second shaft hole 321 is aligned with the second through hole 15. The second rotating shaft 22 of the swing blade 2 in the air outlet channel 11 passes through the second through hole 15 and is inserted into the second shaft hole 321. It can be understood that the second mounting groove 14 is used to limit the installation of the second mounting base 32, which can improve the stability of the connection between the second mounting base 32 and the swing blade 2.

[0069] Similarly, the first mounting base 31 and the frame 1 can be detachably connected by screws, pins, clips, dowels, etc., without specific limitations, and can be selected according to needs. Combining the detachable connection method of the first mounting base 31 and the frame 1, both mounting bases are detachably connected to the frame 1, which can further improve the assembly and disassembly efficiency of the air outlet device 100.

[0070] like Figure 3 As shown, in one embodiment of this utility model, the air outlet duct 11 has a first air passage 111, and the swing blades 2 can be installed into the air outlet duct 11 from the first air passage 111. The opening of the second mounting groove 14 is arranged facing the first air passage 111. (Referring to the reference...) Figure 1 and Figure 2 The second mounting slot 14 and the first air outlet 111 are both arranged along the second direction, so that the second mounting base 32 and the swing blade 2 can be installed from the same side of the frame 1, which helps to reduce the assembly difficulty and improve production efficiency.

[0071] In one embodiment of this utility model, the second through hole 15 has a second clearance notch that extends axially along the second rotating shaft 22. This second clearance notch faces the same side as the opening of the second mounting groove 14 and the first air outlet 111. During assembly, the second mounting base 32 is first inserted into the second mounting groove 14, then the swing blade 2 is inserted into the air outlet channel 11, and finally the second rotating shaft 22 is inserted into the first shaft hole 311 through the mounting port 322, with the first rotating shaft 21 inserted into the first through hole 13 from the first clearance notch. As can be seen, by providing a second clearance notch connecting the second through hole 15, the assembly difficulty of the air outlet device 100 can be further reduced.

[0072] Combined with the first mounting base 31, the specific installation method of the air outlet device 100 can be as follows: first, the first mounting base 31 and the second mounting base 32 are respectively installed into the first mounting groove 12 and the second mounting groove 14; then, the swing blade 2 is installed into the air outlet channel 11; the first rotating shaft 21 is inserted into the first shaft hole 311 of the first mounting base 31; and then the second rotating shaft 22 is pressed from the mounting port 322 of the second mounting base 32 into the second shaft hole 321 to complete the assembly. The assembly steps are simple and efficient.

[0073] In one embodiment of this utility model, a second hook 324 is provided on the second side of the second mounting base 32, and a second slot 141 is provided on the groove wall of the second mounting groove 14 corresponding to the second hook 324. When the second mounting base 32 is inserted into the second mounting groove 14, the second hook 324 engages in the second slot 141, making the second mounting base 32 detachably connected to the frame 1. Alternatively, a slot may be provided on the second mounting base 32, and a hook may be provided on the groove wall of the second mounting groove 14, so that the first mounting base 31 can engage in the first mounting groove 12.

[0074] like Figure 2 As shown, in one embodiment of this utility model, the air outlet device 100 includes a plurality of swing blades 2, which are spaced apart in the air outlet channel 11 along a third direction. The air outlet device 100 also includes a drive assembly 4 mounted on a second mounting base 32. The drive assembly 4 includes a drive motor 41, an eccentric wheel 42, and a transmission link 43. (Refer to reference...) Figures 6 to 8 The second mounting base 32 is also provided with a threaded hole 326 and a positioning post 327. The drive motor 41 is positioned at the second mounting base 32 from below the frame 1 through the positioning post 327, and the drive motor 41 is connected to the second mounting base 32 by screwing screws into the threaded hole 326. The output end of the drive motor 41 is set along the first direction and connected to the eccentric wheel 42. The eccentric wheel 42 is set through the clearance groove 323 of the second mounting base 32.

[0075] The transmission connecting rod 43 is located inside the air outlet duct 11 and is connected to the eccentric wheel 42 for transmission.

[0076] In one embodiment of the present invention, the air outlet device 100 further includes a drive component 4, which can be disposed on any one of the first mounting base 31, the second mounting base 32 and the frame 1. The mounting position is not specifically limited and can be set according to requirements.

[0077] In one embodiment of this utility model, the frame 1 is made of bulk molding compound (BMC) material. For example, the air outlet device 100 can be applied to an electric heater. The frame of the air outlet device of existing electric heaters is generally made of PBT / PET fiber heat-resistant material. Its frame is close to the heating element. After heating, an odor will appear and hot air will be blown out, resulting in a poor user experience.

[0078] In this embodiment, the frame 1 is made of BMC material, which has excellent heat resistance. The heating element 200 does not produce any odor after heating, effectively improving the user experience. However, BMC material is brittle and easily breaks under external force, making it inconvenient to screw the drive motor 41 in place. Therefore, in one embodiment of this solution, the drive assembly 4 is fixed on the second mounting base 32, which solves the problem of inconvenience in installing the drive assembly 4 when using BMC material in the frame 1. Of course, in addition to using BMC material, the frame 1 can also be made of high-temperature resistant plastics such as PPS and PI, which can be selected according to requirements.

[0079] In one embodiment of this utility model, the first mounting base 31 and / or the second mounting base 32 can be made of polyoxymethylene (POM) or nylon. Both POM and nylon materials have excellent wear resistance, which can effectively reduce the friction between the first mounting base 31 / second mounting base 32 and the swing blade 2, extend the service life, and reduce the performance degradation caused by wear. Furthermore, POM has good self-lubricating properties, maintaining good lubrication even with little or no oil, which can improve the noise problem caused by friction between the first rotating shaft 21, the second rotating shaft 22 and the first mounting base 31, the second mounting base 32, and also helps reduce maintenance costs. Both POM and nylon can be molded using common machining methods, making them easy to manufacture and process into the required shapes.

[0080] In another embodiment of the present invention, the air outlet device 100 includes a frame 1, an air swing blade 2 and a first mounting base 31. The frame 1 has an air outlet channel 11. The air swing blade 2 extends along the height direction and is oscillatingly disposed in the air outlet channel 11. The first mounting base 31 is detachably disposed at the upper end of the frame 1. The upper end of the air swing blade 2 is provided with a first rotating shaft 21. The first mounting base 31 is correspondingly provided with a first shaft hole 311. The first rotating shaft 21 is rotatably disposed in the first shaft hole 311.

[0081] It should be noted that, in this embodiment, a second rotating shaft 22 may be provided at the lower end of the swing blade 2, and a second shaft hole 321 may be provided on the frame 1 corresponding to the second rotating shaft 22. Alternatively, this embodiment also includes a second mounting base 32, which is integrally formed with the frame 1, and the second shaft hole 321 is provided on the second mounting base 32. In this embodiment, the second rotating shaft 22 at the lower end of the swing blade 2 may directly contact the frame 1 or the second mounting base 32, which can be set according to requirements.

[0082] This utility model also proposes an electrical device, which includes an air outlet device 100. The specific structure of the air outlet device 100 is as described in the above embodiments. Since this electrical device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0083] like Figure 2 and Figure 3 As shown, in one embodiment, the electrical device includes an electric heater, which includes an air outlet device 100 and a heating element 200. The frame 1 is provided with an air inlet 112a and an air outlet 111a communicating with the air outlet channel 11. The heating element 200 is disposed at the air inlet 112a. The airflow flows from the air inlet 112a to the air outlet 111a in a second direction, and sends the heat emitted by the heating element 200 out of the air outlet 111a. The swing blades 2 realize the swinging effect. Of course, in some other embodiments of this utility model, the electrical device may also include devices with air outlet and swinging requirements, such as air conditioners and hot air blowers, which are not specifically limited here.
