Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a vertical fan oscillating head structure. Background Technology

[0002] In modern home and office environments, electric fans, as basic air circulation and cooling devices, are constantly being designed and technologically advanced to meet users' growing needs. Automatic oscillation is a key feature of these fans, increasing the coverage of airflow and thus improving comfort. However, despite the variety of electric fans on the market, including standing fans and circulating fans, most rely on motor drives to achieve automatic oscillation.

[0003] Currently, automatic oscillating floor fans on the market typically employ two main oscillation mechanisms: mechanical and electronic. Mechanical fans achieve oscillation by rotating a main motor to drive a gearbox, while electronic fans use an independent synchronous motor to control the oscillation. Although both methods can provide automatic oscillation within a certain angle range, they generally share a common technical limitation—they cannot manually oscillate 360°.

[0004] This limitation stems from the following aspects:

[0005] Limitations of structural design: Traditional fan designs typically include limiting devices to prevent excessive rotation from causing internal wiring tangling or mechanical damage. This makes it impossible to exceed the set maximum oscillation angle (such as 75° or 150°) even when manually operated, let alone achieve 360° omnidirectional rotation.

[0006] Complexity of the transmission mechanism: In order to achieve 360° unobstructed manual oscillation, the internal transmission mechanism of the fan needs to be redesigned to ensure that it can support automatic oscillation driven by the motor, as well as allow users to freely make omnidirectional manual adjustments.

[0007] As consumers demand greater flexibility and versatility from products, fans that cannot manually oscillate 360° may not fully meet the needs of certain user groups, such as those who require precise control of airflow direction. Utility Model Content

[0008] This invention addresses the shortcomings and deficiencies of existing technologies by providing a vertical fan oscillating head structure that enables precise and stable wind direction adjustment.

[0009] To achieve the above objectives, the present invention provides a vertical fan oscillating head structure, comprising a base, a vertical rod mounted on the base, a fan head assembly mounted on the vertical rod, and an oscillating head assembly mounted on the fan head assembly for driving the fan head assembly to oscillate automatically. It also includes a sleeve fixedly connected to the fan head assembly, a rotating shaft fixed to the sleeve by fasteners, and a connecting pipe movably connected to the rotating shaft. A limiting groove is formed inside the connecting pipe, and an elastic positioning mechanism is installed within the limiting groove. The elastic positioning mechanism includes an elastic element and a plastic steel ball. When the fan head assembly is rotated, the rotating shaft drives the elastic element and the plastic steel ball to rotate synchronously within the limiting groove. Under the action of the elastic element, the plastic steel ball abuts against the inner wall of the limiting groove, thereby achieving stable positioning of the fan head assembly at any angle.

[0010] Furthermore, one end of the elastic element abuts against the limiting groove, and the other end abuts against the plastic steel ball.

[0011] Furthermore, the limiting groove is a spherical groove or a sector-shaped groove.

[0012] Furthermore, the bottom of the rotating shaft is provided with a connecting post, and the top of the connecting tube is provided with a receiving cavity adapted to the connecting post. The connecting post is fixed to the receiving cavity by a locking assembly.

[0013] Furthermore, the locking assembly includes a washer and a screw for locking the rotating shaft within the connecting tube, the washer being disposed between the screw and the rotating shaft.

[0014] Furthermore, the washer is made of any one of metal sheet, plastic, or rubber.

[0015] Furthermore, the elastic element is a compression spring.

[0016] Furthermore, the bottom outer ring of the connecting pipe is provided with a threaded structure, and the top of the upright rod is provided with an internal threaded structure that is compatible with the threaded structure.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a vertical fan oscillating head structure.

[0029] This utility model proposes a vertical fan oscillating head structure.

[0030] In the embodiments of this utility model, such as Figure 1-7 As shown, this oscillating fan structure includes a base 1, a vertical rod 2 mounted on the base 1, a fan head assembly 3 mounted on the vertical rod 2, and an oscillating head assembly 4 mounted on the fan head assembly 3 for driving the fan head assembly 3 to oscillate automatically. It also includes a sleeve 5 fixedly connected to the fan head assembly 3, a rotating shaft 6 fixed to the sleeve 5 by fasteners, and a connecting pipe 7 movably connected to the rotating shaft 6. A limiting groove 71 is formed inside the connecting pipe 7, and an elastic positioning mechanism 8 is installed inside the limiting groove 71. The elastic positioning mechanism 8 includes an elastic element 82 and a plastic steel ball 81. When the fan head assembly 3 is manually rotated, the rotating shaft 6 drives the elastic element 82 and the plastic steel ball 81 to rotate synchronously within the limiting groove 71. Under the action of the elastic element 82, the plastic steel ball 81 abuts against the inner wall of the limiting groove 71 to achieve stable positioning of the fan head assembly 3 at any angle.

[0031] In this embodiment, one end of the elastic element 82 abuts against the limiting groove 71, and the other end abuts against the plastic steel ball 81. When the fan head assembly 3 is manually rotated, the rotating shaft 6 drives the elastic element 82 and the plastic steel ball 81 to rotate synchronously in the limiting groove 71. Under the action of the elastic element 82, the plastic steel ball 81 abuts against the inner wall of the limiting groove 71 to achieve stable positioning of the fan head assembly 3 at any angle.

[0032] In this embodiment, the limiting groove 71 is a spherical groove or a fan-shaped groove. The limiting groove 71 is selected as a spherical groove or a fan-shaped groove to adapt to the positioning and fitting requirements of different shapes. Among them, the spherical groove is more suitable for realizing 360° unrestricted manual head swing, while the fan-shaped groove can be used to limit the range of head swing angle.

[0033] In this embodiment, the bottom of the rotating shaft 6 is provided with a connecting post 61, and the top of the connecting pipe 7 is provided with a receiving cavity adapted to the connecting post 61. The connecting post 61 is fixed to the receiving cavity by a locking assembly. The connecting post 61 is fixed in the receiving cavity by the locking assembly, thereby realizing a stable connection between the rotating shaft 6 and the connecting pipe 7.

[0034] In this embodiment, the locking assembly includes a washer 9 and a screw for locking the rotating shaft 6 within the connecting tube 7. The washer 9 is disposed between the screw and the rotating shaft 6. The washer 9 is made of any one of metal sheet, plastic, or rubber. The washer 9 is used to enhance locking stability and prevent the rotating shaft 6 from loosening within the connecting tube 7. The material of the washer 9 is selected based on actual application requirements.

[0035] In this embodiment, the elastic element 82 is a compression spring.

[0036] In this embodiment, the bottom outer ring of the connecting pipe 7 is provided with a threaded structure, and the top of the upright rod 2 is provided with an internal threaded structure that matches the threaded structure. The connecting pipe 7 and the upright rod 2 are detachably connected through threaded engagement, facilitating installation and disassembly.

[0037] Specifically, the elastic element 82 is preferably a compression spring, which has good elastic recovery performance, ensuring that the plastic steel ball 81 always fits tightly against the inner wall of the limiting groove 71, thereby achieving manual positioning and stable holding of the fan head assembly 3 at any angle. By setting the compression spring and plastic steel ball 81 inside the connecting tube 7 and having them cooperate with the limiting groove 71 inside the connecting tube 7, good damping and shifting feel are achieved during manual oscillation. When adjusting the fan head angle, the user can obtain clear positioning feedback, avoiding random head displacement, thereby achieving precise and stable airflow adjustment. This design has a simple structure and sensitive response, effectively improving the product's operability and user comfort.

[0038] In actual use, when the fan head assembly 3 is manually rotated, the rotating shaft 6 drives the elastic element 82 and the plastic steel ball 81 to rotate synchronously within the limiting groove 71. Under the action of the compression spring, the head of the plastic steel ball 81 maintains elastic contact with the sector-shaped groove inside the connecting tube 7, achieving stable positioning during rotation. As the fan head assembly 3 rotates as a whole, the compression spring compresses and resets between the connecting tube 7 and the rotating shaft 6, thus providing good operational feedback and positioning stability.

[0039] In addition, a connecting post 61 is provided at the bottom of the rotating shaft 6, which can be inserted into the receiving cavity at the top of the connecting tube 7 and locked in place by the washer 9 and screws to ensure a stable and reliable structure. The outer ring at the bottom of the connecting tube 7 is provided with a threaded structure, which can be matched with the internal threaded structure at the top of the support rod 2 to achieve quick installation and disassembly of the entire structure. Users can freely adjust the angle of the fan head according to actual needs, significantly improving the air delivery coverage and spatial adaptability.

[0040] Through the elastic interaction of the compression spring and the 81 plastic steel ball, appropriate damping and speed feedback are generated during manual oscillation, allowing the fan head to stay stably at any angle, avoiding shaking and improving the operating experience.

[0041] Specifically, by setting a limiting groove 71 inside the connecting pipe 7 and installing an elastic positioning mechanism 8 composed of an elastic element 82 and plastic steel balls 81 within it, manual stable positioning of the fan head assembly 3 at any angle is achieved. Compared with the prior art, it has the following significant technical effects and advantages:

[0042] With the design of the elastic positioning mechanism 8, users can freely adjust the fan head to any angle, breaking through the limitation of traditional fans that cannot achieve omnidirectional oscillation due to mechanical constraints, thus improving the flexibility of use and ease of operation.

[0043] This structure not only retains the swing function of the automatic head swing component 4, but also supports manual and flexible adjustment to meet the personalized needs of different users.

[0044] The flexible positioning mechanism 8 is integrated inside the connecting pipe 7. The overall structure is compact with fewer parts, which facilitates assembly and maintenance and helps reduce production costs.

[0045] Under the action of the elastic element 82 (such as a compression spring), the plastic steel ball 81 always fits tightly against the inner wall of the limiting groove 71, so that the fan head can be stably stopped at any angle, avoiding random shaking and improving the user experience.

[0046] The rotating shaft 6 is fixed to the connecting pipe 7 by a locking assembly (such as washer 9 and screws), and is connected to the upright pole 2 by a threaded structure, which not only ensures the stability of the structure, but also supports quick disassembly, making it easy to clean and replace.

[0047] The vertical fan oscillating head structure proposed in this application effectively solves the problem that existing technologies cannot achieve 360° manual oscillation without changing the original automatic oscillation function, and has good practicality and market promotion value.

[0048] This application applies to all types of standing electric fan products, and is especially suitable for home and commercial scenarios that require a high degree of freedom in airflow adjustment.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
