Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] Currently, air outlet devices with different functions in the industry often require the development of different appearance structures, resulting in low versatility between different air outlet devices and a low overall input-output ratio.

[0041] For example, heating and cooling tower fans and single-cooling tower fans have completely different configurations, differing in casing length and vent grille length. Heating and cooling tower fans use two independent motors to drive the cooling and heating modes respectively, while single-cooling tower fans only have one motor to drive the airflow. The significant differences in components between the two products increase production costs. Consequently, the price difference between heating and cooling tower fans and single-cooling tower fans often exceeds 100%. While integrated functions can improve product utilization and reduce space and socket requirements, when the price difference is too large, their purchasing desire decreases significantly, impacting product sales.

[0042] For air outlet devices, the primary requirement is to blow cool air, making it the main selling configuration. Therefore, most air outlet devices on the market only have the single function of blowing cool air, and are mostly only used during hot summer weather. However, to increase product usage scenarios, maximize product value, meet the needs of some consumers requiring both heating and cooling, and significantly reduce investment and the price of multi-functional products, it is necessary to consider using common components for both heating and cooling / cooling-only products. This would allow companies to reduce investment, develop products with various configurations, form a product sales matrix, improve competitiveness, and simultaneously lower the price of multi-functional products, providing consumers with higher cost-effectiveness.

[0043] Based on the above considerations, the applicant, after in-depth research, designed an air outlet device. The air outlet head can be adapted to either a first base or a second base, allowing the air outlet device to choose between the first or second base according to market demand, thereby achieving either a first air outlet mode or a second air outlet mode. This significantly reduces investment costs during the development and production of the air outlet device, thereby correspondingly lowering its selling price and making it more cost-effective.

[0044] See Figure 1 , Figure 2 as well as Figure 3One embodiment of this application provides an air outlet device 100, including a head unit 10, a first base 20, a second base 30, and an air supply assembly 40. The head unit 10 has a first air inlet 11 and a first air outlet 12 that are interconnected. The second base 30 has a first air duct 31 and a second air duct 32 that are interconnected and have different air outlet directions. The air supply assembly 40 is disposed inside the first base 20 or the second base 30, and the air supply assembly 40 has an air supply duct 41 inside. The air outlet device 100 has a first air outlet mode and a second air outlet mode. When the air outlet device 100 is in the first air outlet mode, the head unit 10 is detachably connected to the first base 20, and the air supply duct 41 is connected to the first air inlet 11. When the air outlet device 100 is in the second air outlet mode, the head unit 10 and the second base 30 are detachably connected, the first air duct 31 is connected between the air supply duct 41 and the first air inlet 11, and the second air duct 32 is connected between the air supply duct 41 and the external environment.

[0045] It should be noted that when the air head 10 is connected to the first base 20 or the second base 30, the air head 10 is detachably mounted above the first base 20 or the second base 30. Therefore, when the air outlet device 100 is in the second air outlet mode, the outlet of the second air duct 32 is located below the first air outlet 12, allowing the first air outlet 12 to deliver air at a higher position, and the outlet of the second air duct 32 to deliver air at a lower position, thus meeting the air blowing needs of users in different positions.

[0046] The first air duct 31 and the second air duct 32 in the second base 30 are arranged in different directions. Specifically, the first air duct 31 can be arranged vertically, that is, the outlet of the first air duct 31 opens upward. Correspondingly, the first air inlet 11 on the machine head 10 opens downward. When the machine head 10 and the second base 30 are detachably connected, it is so that the outlet of the first air duct 31 can be tightly connected to the first air inlet 11.

[0047] The second air duct 32 can be set in a horizontal direction, that is, the outlet of the second air duct 32 is opened in a horizontal direction so that the airflow in the second air duct 32 can be blown out in a horizontal direction.

[0048] The air outlet device 100 of this application can be set between a first air outlet mode and a second air outlet mode according to market demand. When the air outlet device 100 needs to work in the first air outlet mode, the head unit 10 is detachably connected to the first base 20, and the air supply component 40 can be housed inside the first base 20 so that the air supply duct 41 is tightly connected to the first air inlet 11 on the head unit 10.

[0049] When the air outlet device 100 needs to operate in the second air outlet mode, the head unit 10 is detachably connected to the second base 30, and the air supply component 40 can be housed inside the second base 30, so that the air supply component 40 is connected to the first air duct 31 and the second air duct 32 respectively. The first air duct 31 can connect the air supply duct 41 and the first air inlet 11. After the airflow is generated in the air supply duct 41, it can enter the first air inlet 11 through the first air duct 31, and then be blown out from the first air outlet 12, or blown out from the second air duct 32.

[0050] Therefore, the components such as the head unit 10 and the air supply assembly 40 in the aforementioned air outlet device 100 have excellent ventilation properties.

[0051] The device can be assembled with either the first base 20 or the second base 30 according to market demand, thus achieving different configurations of the air outlet device 100. This significantly reduces the production cost of the air outlet device 100 and improves efficiency.

[0052] The high cost-performance ratio of the high-efficiency air outlet device is 100.

[0053] Please refer to the following: Figure 1 , Figure 2 as well as Figure 4 In some embodiments, the second base 30 includes a base 33 and an air outlet body 34 detachably assembled inside the base 33, and a second air outlet 331 is provided on the base 33.

[0054] The air outlet body 34 has a second air inlet 341, a first air outlet 342, and a second air outlet 343. The second air inlet 341 and the first air outlet 342 define a first air duct 31. The second air inlet 341 and the first air outlet 343 are connected to the air outlet body 34.

[0055] A second air duct 32 is formed between the second air outlet 343 and the second air supply outlet 331.

[0056] Specifically, the base 33 has an inner cavity in which the air outlet body 34 can be accommodated, and the base 33 can be detachably connected to the head unit 10.

[0057] The base 33 can be detachably connected to the machine head 105 via bolts or snap-fit ​​connections. Similarly, when the first base 20 is detachably connected to the machine head 10, it can also be...

[0058] Connection methods using bolts or clips will not be elaborated here.

[0059] The air outlet body 34 is designed as a hollow structure, and a second air inlet 341, a first air outlet 342, and a second air outlet 343 are respectively opened on the air outlet body 34, so that the second air inlet 341 and the first air outlet 342 are connected.

[0060] The space defines and forms a first air duct 31. When the air outlet body 34 is housed in the inner cavity of the base 33, the second air outlet 343 on the air outlet body 34 and the second air supply outlet 331 on the base 33 are at least partially corresponding, so that...

[0061] The airflow blown out from the second air outlet 343 can be smoothly blown out from the second air supply outlet 331 into the external environment.

[0062] The airflow enters the air outlet body 34 through the second air inlet 341, and is blown out to the external environment through the second air outlet 343 and the second air supply outlet 331 in sequence. Therefore, the second air inlet 341, the second air outlet 343 and the second air supply outlet 331 together define and form a second air duct 32 for airflow to pass through.

[0063] By setting the air outlet body 34, airflow can be blown out from the first air duct 31 or the second air duct 32 in different directions, thereby realizing multi-angle and multi-directional air outlet of the air outlet device 100, making the air outlet device 100 adaptable to more usage scenarios.

[0064] In some embodiments, the air outlet device 100 further includes a heating element 50, which is detachably disposed inside the air outlet body 34 and located on the path through which the airflow flows out from the second air outlet 343.

[0065] Specifically, the heating element 50 is located between the second air inlet 341 and the second air outlet 343. The airflow enters the air outlet body 34 from the second air inlet 341 and blows from the second air outlet 343 to the second air supply outlet 331. During this process, the heating element 50 heats the airflow passing through it, thereby achieving the effect of blowing warm air from the second air supply outlet 331.

[0066] By installing a heating element 50 in the second air duct 32, cold air and warm air can be blown out from the first air duct 31 and the second air duct 32 respectively, so that the air outlet device 100 can meet the different needs of blowing cold air and blowing warm air.

[0067] Furthermore, the heating element 50 can be detachably installed inside the air outlet body 34 by means of a snap-fit ​​connection. Of course, the heating element 50 can also be detachably installed inside the air outlet body 34 by means of bolt connection or other methods.

[0068] Furthermore, as a specific embodiment, the heating element 50 can be configured as a PTC heating device. Of course, the heating element 50 can also be configured as other heating structures, which will not be elaborated here.

[0069] In some embodiments, the air outlet device 100 further includes a switching component 60 disposed on the air outlet body 34, the switching component 60 being movably connected to the air outlet body 34 to selectively close either the first air duct 31 or the second air duct 32.

[0070] Specifically, when the switching component 60 closes the first air duct 31, the second air duct 32 is in a connected state. The airflow in the supply air duct 41 enters the second air duct 32, and the heating element 50 heats the airflow in the second air duct 32. The heated airflow is then blown out from the second air outlet 331, thereby achieving the effect of producing warm air.

[0071] When the switching component 60 closes the second air duct 32, the first air duct 31 is in a connected state. The airflow in the air supply duct 41 enters the first air inlet 11 through the first air duct 31 and is blown out from the first air outlet 12, thereby achieving the effect of producing cold air.

[0072] Therefore, when the air outlet device 100 is in the second air outlet mode, by switching component 60 selectively closing one of the first air duct 31 and the second air duct 32, two air outlet modes, namely, cold air outlet or warm air outlet, can be achieved. That is, when the air outlet device 100 is in the second air outlet mode, the air outlet device 100 is a dual-purpose air outlet device for both cooling and heating.

[0073] Understandably, when the air outlet device 100 is in the first air outlet mode, since the air supply duct 41 is directly connected to the first air inlet 11, the airflow in the air supply duct 41 enters the first air inlet 11 and is blown out from the first air outlet 12, thereby achieving the effect of emitting cold air. That is, when the air outlet device 100 is in the first air outlet mode, the air outlet device 100 is a single-cooling air outlet device 100.

[0074] With the above structure, during the production process of the air outlet device 100, either the first base 20 or the second base 30 can be detachably connected to the head unit 10 according to market demand, thereby providing either a dual-purpose (heating and cooling) air outlet device 100 or a single-purpose (cooling) air outlet device 100. This effectively reduces production costs.

[0075] Please refer to Figure 5 In some embodiments, the switching component 60 includes a rotating shaft 61 and a baffle 62 disposed on the rotating shaft 61. The rotating shaft 61 is rotatably disposed inside the air outlet body 34 and drives the baffle 62 to selectively close either the first air duct 31 or the second air duct 32.

[0076] Specifically, the inner wall of the air outlet body 34 is provided with shaft holes that match the rotating shaft 61. The two ends of the rotating shaft 61 along its own axial direction can be controlled to rotate in the corresponding shaft holes, thereby driving the baffle 62 to rotate synchronously.

[0077] The outer contour of the baffle 62 matches the contours of the first air outlet 342 and the second air outlet 343. As the baffle 62 rotates with the rotating shaft 61, it can be set to correspond to the first air outlet 342 or the second air outlet 343 respectively.

[0078] When the baffle 62 rotates to correspond with the first air outlet 342, the baffle 62 blocks the first air outlet 342, thereby closing the first air duct 31. At this time, the second air duct 32 is connected, and the airflow in the air supply duct 41 is heated by the heating element 50 and then blown out warm air from the second air duct 32.

[0079] When the baffle 62 rotates to correspond with the second air outlet 343, the baffle 62 blocks the second air outlet 343, thereby closing the second air duct 32. At this time, the first air duct 31 is connected, and the airflow in the air supply duct 41 enters the first air inlet 11 through the first air duct 31 and blows out cold air from the first air outlet.

[0080] Therefore, the baffle 62 can be rotated by the rotating shaft 61, thereby quickly switching between cold air mode and warm air mode.

[0081] Please refer to the following: Figure 5 , Figure 6 as well as Figure 7 In some embodiments, a groove 344 is provided on the inner wall of the air outlet body 34, and a sliding post 621 that cooperates with the groove 344 is provided on the baffle 62. The sliding post 621 slides along the groove 344 so that the baffle 62 can selectively close the first air outlet 342 or the second air outlet 343.

[0082] As the baffle 62 rotates with the rotating shaft 61, the sliding column 621 on the baffle 62 slides along the sliding groove 344. This makes the rotation of the baffle 62 with the rotating shaft 61 more stable. It also ensures that the baffle 62 is accurately aligned with either the first air outlet 342 or the second air outlet 343 according to the path opened by the sliding groove 344. When the baffle 62 is aligned with the first air outlet 342, it closes the first air outlet 342, thus closing the first air duct 31. When the baffle 62 is aligned with the second air outlet 343, it closes the second air outlet 343, thus closing the second air duct 32.

[0083] In one specific embodiment, the opening directions of the first air outlet 342 and the second air outlet 343 are perpendicular to each other on the air outlet body 34, with the first air outlet 342 opening upwards and the second air outlet 343 opening horizontally. Thus, the slide groove 344 is formed as a quarter-circle arc on the inner wall of the air outlet body 34. When the slide column 621 slides to the opposite apexes of the slide groove 344, the baffles 62 are respectively positioned corresponding to the first air outlet 342 or the second air outlet 343, thereby smoothly closing the first air outlet 342 or the second air outlet 343.

[0084] Furthermore, for ease of installation, the main air outlet 34 is divided into a first part and a second part that are symmetrical to each other. The first part and the second part together form a second air inlet 341, a first air outlet 342, and a second air outlet 343. In addition, the first part and the second part can be detachably connected by snap-fit ​​connection, bolt connection, or other connection methods.

[0085] Symmetrical shaft holes and symmetrical sliding grooves 344 are respectively opened on the inner walls of the first and second parts facing each other, so that the rotating shaft 61 and the baffle 62 can be stably installed inside the air outlet body 34, and the baffle 62 can rotate more smoothly with the rotating shaft 61.

[0086] Please refer to it again. Figure 1 and Figure 4 In some embodiments, the switching component 60 further includes a first driving member 63 that is drivenly connected to the rotating shaft 61, the first driving member 63 being used to drive the rotating shaft 61 to rotate.

[0087] Specifically, the first driving member 63 can be configured as a drive motor, and the rotating shaft 61 has a connecting hole on one end face along its own axis that matches the drive shaft of the first driving member 63. The drive shaft of the first driving member 63 is inserted into the connecting hole, thereby driving the rotating shaft 61 to rotate around its own axis.

[0088] In some embodiments, the second base 30 further includes a grille 35, which is detachably disposed within the second air outlet 331.

[0089] Specifically, a buckle can be provided on the inner wall of the second air outlet 331, and a slot for engaging the buckle can be provided on the outer periphery of the grille 35, so that the grille 35 can be detachably installed in the second air outlet 331.

[0090] Of course, the grille 35 can also be detachably installed in the second air outlet 331 by bolt connection or other connection methods, which will not be elaborated here.

[0091] The grille 35 is installed inside the second air outlet 331 and can filter out larger pollutants in the external environment, thereby providing a certain degree of protection for the internal structure of the second base 30.

[0092] In some embodiments, the air supply assembly 40 includes a volute 42 and a fan wheel 43. The fan wheel 43 is disposed inside the volute 42 and can rotate around itself to form an air supply duct 41 inside the volute 42.

[0093] The impeller 43 rotates around itself to generate airflow. The airflow passes through the air supply duct 41 and enters the first air inlet 11 or the air outlet body 34, and then exits from the first air outlet 12 or the second air outlet 331.

[0094] As a specific embodiment, to facilitate the installation of the air supply assembly 40, the volute 42 is divided into a first housing and a second housing that are symmetrical to each other. The first housing and the second housing are detachably connected by snap-fit ​​connection, bolt connection or other connection methods, and the impeller 43 is housed between the first housing and the second housing. When the impeller 43 rotates on its own, an air supply duct 41 is formed between the first housing and the second housing.

[0095] In some embodiments, the air supply assembly 40 further includes a second drive member 44 that is driven to drive the impeller 43 to rotate.

[0096] The second driving component 44 can be configured as a drive motor and drivenly connected to the impeller 43. Specifically, a through hole is opened in the first housing or the second housing so that the drive shaft of the second driving component 44 can pass through the through hole and drively connect to the impeller 43 inside the volute 42 to drive the impeller 43 to rotate.

[0097] In some embodiments, the air outlet device 100 further includes a base 70, and the air supply assembly 40 is detachably mounted on the base 70. When the air outlet device 100 is in a first air outlet mode, the first base 20 is connected between the head unit 10 and the base 70. When the air outlet device 100 is in a second air outlet mode, the second base 30 is connected between the head unit 10 and the base 70.

[0098] like Figure 3 As shown, when the air outlet device 100 is in the first air outlet mode, the air supply assembly 40 is first placed on the base 70, and then the base 70 together with the air supply assembly 40 is connected to the lower end of the first base 20, so that the first base 20 covers the air supply assembly 40, and the upper end of the first base 20 is detachably connected to one end of the first air inlet 11 of the head unit 10, thereby completing the assembly of the air outlet device 100 in the first air outlet mode. At this time, the airflow in the air supply assembly 40 enters the first air inlet 11 from the air supply duct 41 and blows out cold air from the first air outlet 12, thereby realizing the single cooling mode.

[0099] like Figure 2When the air outlet device 100 is in the second air outlet mode, the air supply component 40 is first placed on the base 70, and then the base 70 together with the air supply component 40 is connected to the lower end of the second base 30, so that the second base 30 covers the air supply component 40, and the upper end of the second base 30 is detachably connected to one end of the first air inlet 11 of the head 10, thereby completing the assembly of the air outlet device 100 in the second air outlet mode.

[0100] At this time, by controlling the rotating shaft 61 to drive the baffle 62 to rotate, the baffle 62 closes the first air outlet 342, and the second air outlet 343 opens. The airflow in the air supply duct 41 enters the second air duct 32 from the second air inlet 341, and forms warm air under the heating action of the heating element 50. It is then blown out through the second air outlet 343 and the second air supply outlet 331 on the second base 30, thereby realizing the warm air mode.

[0101] When the baffle 62 rotates with the shaft 61 and closes the second air outlet 343, the first air outlet 342 opens. The airflow in the air supply duct 41 enters the first air duct 31 from the second air inlet 341, and enters the first air inlet 11 from the first air outlet 342, and finally blows out cold air from the first air outlet 12 on the machine head 10, thereby realizing the cold air mode.

[0102] Based on the same concept as the air outlet device 100 described above, this application also provides a bladeless fan, including the air outlet device 100 as described above.

[0103] In practical use, when it is necessary to assemble an air outlet device 100 with a single cooling mode, the air supply component 40 is placed on the base 70, and the base 70 together with the air supply component 40 is connected to the lower end of the first base 20, so that the first base 20 covers the air supply component 40. Then, the upper end of the first base 20 is detachably connected to the end of the head unit 10 where the first air inlet 11 is opened, so that the outlet of the air supply duct 41 can be connected to the first air inlet 11.

[0104] The airflow in the air supply duct 41 enters the machine head 10 through the first air inlet 11 and blows out cold air from the first air outlet 12 opened on the machine head 10.

[0105] When assembling an air outlet device 100 with both heating and cooling air outlet modes, the air supply component 40 is placed on the base 70, and the base 70, together with the air supply component 40, is connected to the lower end of the second base 30, so that the second base 30 covers the air supply component 40. Then, the upper end of the second base 30 is detachably connected to the end of the head unit 10 where the first air inlet 11 is located, so that the first air outlet 342 on the air outlet body 34 is connected to the first air inlet 11.

[0106] At this time, the air outlet device 100 has both a cold air mode and a warm air mode. When the cold air mode is turned on, the baffle 62 rotates with the rotating shaft 61 and closes the second air outlet 343. At this time, the first air outlet 342 opens, and the airflow in the air supply duct 41 enters the first air duct 31 from the second air inlet 341, and enters the first air inlet 11 from the first air outlet 342, and finally blows out cold air from the first air outlet 12.

[0107] When the warm air mode is turned on, the baffle 62 rotates with the rotating shaft 61 and closes the first air outlet 342. At this time, the second air outlet 343 opens, and the airflow in the air supply duct 41 enters the second air duct 32 from the second air inlet 341. Under the heating action of the heating element 50, warm air is formed and blown out from the first air outlet 12.

[0108] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
