Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] 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. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] See Figure 1 This application provides an electrical device 1000. The following description uses a circulating fan as an example to illustrate part of the structure of the electrical device 1000. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electrical device 1000 may also be a cooling fan, electric heater, or other devices, which are not limited here.

[0042] Electrical equipment 1000 includes a main body 100 and an air supply device 300. The main body 100 is generally columnar in shape and mainly serves to support, connect, and house components. The air supply device 300 is installed at one end of the main body 100 to create a directional airflow. It is understood that the specific structure of electrical equipment 1000 is not limited to this and can be configured as needed to meet different requirements.

[0043] In the following embodiments, the length direction of the main body 100 is defined as the first direction (i.e. Figure 1 The X direction in the middle), the width direction is the second direction (i.e. Figure 1 The Y direction in the middle), and the height direction is the third direction (i.e. Figure 1 In the Z direction), the first direction, the second direction, and the third direction intersect each other, and in a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0044] Please combine Figure 2 , Figure 3 As shown, the air supply device 300 includes a housing 310, a first bracket 320, a second bracket 340, an air duct housing 350, and a fan wheel 360.

[0045] The outer casing 310 includes an outer casing body 312, an air inlet grille 314, and an air outlet grille 316. The outer casing body 312 is generally a hollow cylindrical structure open at both ends, and its central axis extends along a first direction. An air inlet is formed at each opposite end of the outer casing body 312 in the first direction, and an arc-shaped air outlet extending around the first direction is formed on the outer periphery of the outer casing body 312. Two disc-shaped air inlet grilles 314 are respectively installed at the two air inlets of the outer casing 310, and the arc-shaped air outlet grille 316 is installed at the air outlet of the outer casing 310, thereby serving functions such as protection and guiding airflow. It is understood that the specific shape and structure of the outer casing 310 are not limited to this and can be configured as needed to meet different requirements.

[0046] The first bracket 320 and the second bracket 340 are installed at intervals along the first direction at opposite ends of the axial direction of the housing 310. The outer contours of the first bracket 320 and the second bracket 340 are roughly circular and match the shape of the air outlet of the housing 310. The air outlet grille 316 can be fixed relative to the housing 310 by the first bracket 320 and the second bracket 340.

[0047] The duct housing 350 is generally a hollow cylindrical structure. It is rotatably mounted between the first support 320 and the second support 340 and housed within the outer casing 310, with the central axis of the duct housing 350 coinciding with the central axis of the outer casing 310. The duct housing 350 has an air inlet at each of its opposite ends in the first direction, and these air inlets are connected to the air inlets of the outer casing 310. An air outlet is provided on the outer periphery of the duct housing 350, and this outlet is connected to the air outlet of the outer casing 310.

[0048] In one specific embodiment, the duct housing 350 includes a first duct housing 352 and a second duct housing 354, which are spliced ​​together in a first direction to form a complete duct housing 350. In other embodiments, the duct housing 350 may also be an integrally formed structure.

[0049] The impeller 360 is coaxially arranged with the duct housing 350 and is rotatably installed inside the duct housing 350 around a first direction. The rotation of the impeller 360 can create negative pressure, so outside air flows into the duct housing 350 through the air inlet of the outer shell 310 and the air inlet of the duct housing 350, and then flows out through the air outlet of the duct housing 350 and the air outlet of the outer shell 310 under the action of the negative pressure of the impeller 360.

[0050] like Figures 2 to 4As shown, in order to achieve the oscillation function, the air supply device 300 of this application also includes an oscillation drive assembly 370. The oscillation drive assembly 370 is located inside the housing 310 and installed on the first bracket 320. The oscillation drive assembly 370 is connected to the air duct housing 350 for driving the air duct housing 350 to rotate relative to the housing 310.

[0051] Thus, compared to the prior art where the oscillation drive component 370 is located outside the housing 310, the oscillation drive component 370 in this application is integrated inside the housing 310 and fixed by the first bracket 320. This makes full use of the fixing function of the first bracket 320 and the internal space of the housing 310, making the overall structure of the air supply device 300 more compact and reasonable, effectively reducing the overall volume of the air supply device 300, making the overall structure of the air supply device 300 more aesthetically pleasing, and facilitating the miniaturization of the air supply device 300.

[0052] Please combine Figure 4 , Figure 5 As shown, specifically, the first bracket 320 includes a first bracket body 321 and a first support ring 323. The first bracket body 321 is generally in the shape of a cross, including a first horizontal bar 3212 and a first vertical bar 3214 that are arranged in a cross direction. The first horizontal bar 3212 extends along a second direction, and the first vertical bar 3214 extends along a third direction. The first support ring 323 is generally circular around the outer periphery of the first bracket body 321. The first support ring 323 is provided with a plurality of grille mounting holes, all of which are arranged at intervals along the circumference of the first support ring 323. The air outlet grille 316 is connected to the first bracket 320 through these grille mounting holes.

[0053] The second support 340 can be constructed similarly to the first support 320, including a second support body and a second support ring. The second support body is roughly cross-shaped, including a second horizontal bar and a second vertical bar that are intersected, with the second horizontal bar extending along a second direction and the second vertical bar extending along a third direction. The second support ring is roughly circular, surrounding the outer periphery of the support body. The second support ring has multiple grille mounting holes, all of which are spaced apart along the circumference of the second support ring. The air outlet grille 316 is connected to the second support 340 through these grille mounting holes.

[0054] Further, please refer to Figures 5 to 7The first bracket 320 has two first mounting posts 3216 protruding from one end of its first bracket body 321, which connects to the main body 100. These two first mounting posts 3216 are spaced apart in a second direction, and the central axis of each first mounting post 3216 extends along a third direction. Similarly, the second bracket 340 has two second mounting posts protruding from one end of its second bracket body, which connects to the main body 100. These two second mounting posts are spaced apart in a second direction, and the central axis of each second mounting post extends along a third direction. The main body 100 has two first mounting holes and two second mounting holes on opposite sides in the first direction, respectively. The two first mounting holes and the two second mounting holes are spaced apart in the second direction.

[0055] Thus, two first mounting posts 3216 are respectively inserted into two first mounting holes along a third direction. Screws and other fasteners are sequentially inserted into the first mounting holes and the first mounting posts 3216 along a third direction to fix the first bracket 320 to the main body 100. Two second mounting posts are respectively inserted into two second mounting holes along a third direction. Screws and other fasteners are sequentially inserted into the second mounting holes and the second mounting posts along a third direction to fix the second bracket 340 to the main body 100. It can be understood that the number and location of the first mounting posts 3216, first mounting holes, second mounting posts, and second mounting holes are not limited to this and can be configured as needed to meet different installation requirements.

[0056] like Figure 5 , Figure 7 and Figure 8 As shown, the air supply device 300 also includes a fixing base 330, which is located on the side of the first bracket 320 facing the second bracket 340. The oscillation drive assembly 370 is mounted on the fixing base 330. Specifically, the fixing base 330 is located at the end of the first vertical rod 3214 of the first bracket body 321 near the main body 100, and is integrally formed with the first bracket body 321. It can be understood that the position of the fixing base 330 is not limited to this, and can be set as needed to fix the oscillation drive assembly 370 in different positions.

[0057] The oscillation drive assembly 370 is mounted on the first bracket body 321 via a fixed base 330. The oscillation drive assembly 370 includes a drive motor 372 and a drive wheel 374. The drive motor 372 is mounted on the fixed base 330, and the drive wheel 374 is located outside the fixed base 330 and connected to the output shaft of the drive motor 372. The drive wheel 374 is connected to the air duct housing 350 in a transmission connection. The drive wheel 374 can rotate synchronously under the drive of the drive motor 372, thereby driving the air duct housing 350 to rotate relative to the outer shell 310.

[0058] like Figure 9As shown, in one specific embodiment, the outer periphery of the duct housing 350 is provided with a plurality of transmission posts 356. All transmission posts 356 are arranged at intervals along the circumference of the duct housing 310. As the drive wheel 374 rotates, the teeth of the drive wheel 374 can be cyclically inserted between two adjacent transmission posts 356, thereby driving the duct housing 350 to rotate. In other embodiments, the outer periphery of the duct housing 350 is provided with a transmission rack extending along the circumference of the duct housing 350. The drive wheel 374 can mesh with the transmission rack to drive the duct housing 350 to rotate.

[0059] Please refer to it again. Figure 5 and Figure 8 In some embodiments, the mounting base 330 includes a surrounding rib 332, which surrounds the outer periphery of the drive motor 372 in the circumferential direction, thereby fixing and protecting the drive motor 372 while strengthening the structure and reducing vibration and noise.

[0060] Furthermore, the fixing base 330 also includes fixing posts 334. Two fixing posts 334 are located on the outside of the surrounding rib 332 and are spaced apart in the circumferential direction of the surrounding rib 332. The drive motor 372 is provided with lugs corresponding to the fixing posts 334. Screws and other fasteners can pass through the lugs and be inserted into the fixing posts 334, thereby further fixing the drive motor 372 and the fixing base 330 and preventing the drive motor 372 from coming out of the fixing base 330.

[0061] The aforementioned air supply device 300 and the electrical equipment 1000 equipped therewith, the oscillation drive component 370 is mounted on the first bracket 320 via the fixed base 330 and located inside the outer casing 310. While not interfering with the rotation of the air duct casing 350, it reduces the overall volume of the air supply device 300, making the overall structure of the air supply device 300 more compact, thereby making the appearance of the electrical equipment 1000 more concise and beautiful, which is conducive to the integration and miniaturization of the electrical equipment 1000.

[0062] 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.

[0063] 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.
