Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan that is easy to adjust. Background Technology

[0002] Fans, as basic devices for regulating airflow, providing heat dissipation and ventilation, are widely used in people's daily lives. To meet the need for cooling multiple people simultaneously, some dual-head fans have emerged in the current technology.

[0003] However, existing dual-head fans typically only allow adjustment of the fan head's airflow direction, offering limited flexibility in adjusting the overall installation position and angle. This is particularly problematic in office environments with workstation partitions, where the partitions prevent effective adjustment of the fan body or fan head to the appropriate position, hindering independent and effective cooling for users at different workstations. This poor installation compatibility and lack of adjustment flexibility limit the application range and effectiveness of existing dual-head fans. Therefore, improvements to the existing technology are urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a fan that is easy to adjust.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fan that is easy to adjust, including a mounting clip and two fan bodies. A base plate is rotatably connected to the mounting clip. A mounting groove is provided on the top of the base plate. A mounting plate is rotatably connected to the inner wall of the mounting groove through a rotating rod. A gooseneck tube is connected to the top of the mounting plate through two connectors.

[0006] The bottom of the fan body is equipped with a ball joint, and the top of the gooseneck tube is equipped with a ball mount that mates with the ball joint. The ball joint is connected to the ball mount.

[0007] Furthermore, the mounting groove has a threaded hole, and the mounting plate has a through hole. The mounting plate is threaded through the through hole and screwed into the threaded hole by bolts.

[0008] Furthermore, the connector includes a threaded portion fixed to the bottom of the gooseneck tube, and the mounting plate has a threaded hole portion that mates with the threaded portion, and the threaded portion and the threaded hole portion are spirally connected.

[0009] Furthermore, a conductive terminal is installed at the bottom of the threaded portion, and a conductive end that is pressed against the conductive terminal is provided inside the threaded hole portion.

[0010] Furthermore, a battery mounting compartment is provided at the bottom of the base plate, and a battery is installed in the battery mounting compartment. The battery is electrically connected to the conductive end in the threaded hole through a wire.

[0011] Furthermore, a charging interface is provided on one side of the base plate, which is electrically connected to the battery.

[0012] Preferably, the mounting clip is a C-shaped clip structure.

[0013] Preferably, the surface of the rotating rod is provided with a damping pad.

[0014] Preferably, the mounting clip is rotatably connected to the base plate via a damping shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By incorporating a mounting clip connecting the base plate, the fan can be easily clamped and fixed in various locations such as desktops or workstation partitions, significantly improving the compatibility of installation scenarios. Especially in scenarios with workstation partitions, such as offices, a rotatable mounting plate is installed on the base plate, connecting two gooseneck tubes and the fan body. This allows the entire fan assembly to rotate on the base plate, enabling the fan body to be rotated above the partition. This solves the problem in existing technologies where dual-head fans cannot independently deliver airflow to two users at different workstations through a partition. Simultaneously, the two fan bodies are connected by adjustable gooseneck tubes, allowing for independent adjustment of their position and angle. The ball joint formed by the spherical connector at the bottom of the fan body and the spherical mounting base at the top of the gooseneck tube further improves the convenience and precision of adjusting the fan's airflow angle, thus achieving independent cooling for two users. This solves the problems of intermittent oscillating airflow in existing technologies and the inability of dual-head fans to achieve independent airflow adjustment. Therefore, this conveniently adjustable fan has the advantages of flexible installation, easy adjustment, and the ability to achieve independent cooling, effectively overcoming the shortcomings of existing technologies.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] As a basic air conditioning device, the development of fans has accompanied humanity's continuous pursuit of a comfortable environment. From early simple mechanical structures to today's diverse electric and intelligent products, the functions and forms of fans have been constantly enriched. However, in certain specific application scenarios, such as office environments where partitions are often installed between workstations, existing fans, especially double-headed fans, often struggle to effectively bypass or traverse these partitions to provide independent and flexible airflow to users on either side. Traditional oscillating fans have airflow intervals, and while existing double-headed fans can blow air onto two people simultaneously, their overall installation position and head angle adjustment are often limited, making them unsuitable for complex environments such as partitions, resulting in poor airflow performance or poor installation compatibility. To solve this problem, this invention provides a fan that is easy to adjust. Through ingenious structural design, particularly the inclusion of a mounting plate that can rotate on the base plate and an independently adjustable gooseneck tube connected to a ball joint, this fan significantly improves the compatibility of installation scenarios and the flexibility of airflow adjustment, making it especially suitable for office environments with partitions.

[0025] like Figures 1 to 5 The fan shown is easy to adjust, including a mounting clip 1 and two fan bodies 16. A base plate 2 is rotatably connected to the mounting clip 1. A mounting groove 18 is opened on the top of the base plate 2. A mounting plate 6 is rotatably connected to the inner wall of the mounting groove 18 through a rotating rod 17. A gooseneck tube 3 is connected to the top of the mounting plate 6 through two connectors.

[0026] A ball joint 4 is installed at the bottom of the fan body 16, and a ball mounting base 5 that mates with the ball joint 4 is installed at the top of the gooseneck tube 3. The ball joint 4 is connected to the ball mounting base 5.

[0027] As one embodiment of this utility model, a threaded hole 9 is provided in the mounting groove 18, and an opening 8 is provided through the mounting plate 6. The mounting plate 6 is threadedly connected to the threaded hole 9 by a bolt 7 passing through the opening 8.

[0028] Compared with existing technologies, the easily adjustable fan of this invention has significant advantages. Existing dual-head fans are typically fixed units; after installation, only the direction of the fan head can be adjusted, not the overall offset relative to the mounting point. Existing structures struggle to achieve this when the fan assembly needs to be mounted as a whole on a workstation partition, with the fan body positioned above the partition. This invention, however, utilizes a rotatable mounting plate 6 on the base plate 2, allowing the mounting plate 6, which supports the fan body 16, to rotate on the base plate 2. When the mounting clip 1 is clamped at the edge of the partition, rotating the mounting plate 6, along with the gooseneck tube 3 and the fan body 16, allows the mounting plate 6, along with the gooseneck tube 3 and the fan body 16, to be rotated from one side of the base plate 2 to the other, for example, to above the partition. This solves the problem of the fan body 16 being obstructed by the partition and greatly improves installation compatibility in partitioned environments. In addition, the two fan bodies 16 are connected by independent gooseneck tubes 3, and the fan bodies 16 and gooseneck tubes 3 are connected by ball joints 4 and ball mounting bases 5. This allows the position and blowing angle of the two fan bodies 16 to be flexibly adjusted completely independently, so as to accurately target the two users on both sides of the partition and provide personalized air supply. This overcomes the air supply interval problem of existing oscillating fans and the problem of insufficient adjustment flexibility of traditional dual-head fans.

[0029] In use, the easily adjustable fan can be fixed to the edge of a desktop or workstation partition using the mounting clip 1. When the entire fan assembly needs to be mounted on the workstation partition, the mounting clip 1 can be clamped to the edge of the partition, with the base plate 2 located on one side of the partition. At this time, by rotating the mounting plate 6, the gooseneck tube 3 and the fan body 16 on it can be rotated around the rotating rod 17 within the mounting groove 18, thus rotating the entire fan assembly above the partition. After rotation, the mounting plate 6 can be fixed (e.g., using bolts). Subsequently, the two gooseneck tubes 3 can be bent separately to make initial adjustments to the position and direction of the two fan bodies 16. Finally, by rotating the ball joint 4 at the bottom of the fan body 16 within the ball joint 5 at the top of the gooseneck tube 3, the blowing angle of the fan body 16 can be finely adjusted to precisely align with the two users. In this process, the mounting clip 1 and the base plate 2 provide a stable mounting foundation; the rotating connection structure of the mounting groove 18, the rotating rod 17, and the mounting plate 6 allows the fan body 16 to adapt to special installation environments such as partitions, enabling positional offset; the two gooseneck tubes 3 provide independent and flexible support, allowing for a wide range of positional adjustments to the two fan bodies 16; and the spherical joint formed by the spherical connector 4 and the spherical mounting base 5 provides flexible and precise angle adjustment capabilities. The entire structure works in concert to achieve convenient installation, flexible adjustment, and independent airflow cooling for two users of the fan body 16, effectively solving the technical problems of poor installation compatibility and inflexible adjustment in existing technologies.

[0030] As one embodiment of this utility model, the connector includes a threaded portion 13 fixed to the bottom of the gooseneck tube 3, and a threaded hole portion that mates with the threaded portion 13 is provided on the mounting plate 6, and the threaded portion 13 and the threaded hole portion are spirally connected.

[0031] During operation, a threaded hole 9 is provided on the inner wall of the mounting groove 18 to fix the position of the mounting plate 6 relative to the base plate 2. Simultaneously, a through hole 8 is provided at a corresponding position on the mounting plate 6. When the mounting plate 6 rotates to the predetermined position, the through hole 8 aligns with the threaded hole 9. Specifically, the bolt 7 is designed to pass through the through hole 8 and screw into the threaded hole 9. This threaded connection provides a reliable fixing method, preventing accidental rotation of the mounting plate 6 during use. As a preferred embodiment, the bolt 7 can be a butterfly bolt, allowing the user to manually tighten or loosen it without tools, thus easily locking or unlocking the rotation of the mounting plate 6. Therefore, by setting the mating structure of the bolt 7, the through hole 8, and the threaded hole 9, the mounting plate 6 can be securely locked after rotation adjustment to the desired angle. This ensures that the airflow direction of the fan body 16 is stably maintained after adjustment, avoiding displacement due to accidental contact or vibration, thereby ensuring continuous and effective airflow to the user and improving the stability and reliability of the device.

[0032] In one embodiment of this utility model, a conductive terminal 15 is installed at the bottom of the threaded portion 13, and a conductive end is provided inside the threaded hole portion to be pressed against the conductive terminal 15; when the threaded portion 13 is screwed into the threaded hole portion, the conductive terminal 15 and the conductive end come into contact with each other and form a press-fit, thereby establishing an electrical connection.

[0033] As one embodiment of this utility model, a battery mounting compartment 10 is provided at the bottom of the base plate 2, and a battery 11 is installed in the battery mounting compartment 10. The battery 11 is electrically connected to the conductive end in the threaded hole through a wire.

[0034] The battery 11 serves as the power source for the device, providing electrical energy to drive the fan body 16. The battery mounting compartment 10 may have a structure for easy insertion and removal of the battery 11, such as a door or cover. The battery 11 is electrically connected to a conductive terminal in a threaded hole via a wire. This conductive terminal is an interface or contact for transferring electrical energy from the battery 11 to the conductive terminal. By integrating the battery mounting compartment 10 and the battery 11 inside the base plate 2, the entire fan device can be powered by the battery 11. Compared to solutions requiring an external power adapter or USB cable, the built-in battery 11 makes the fan body 16 more portable and flexible in use, allowing it to be used in locations without power outlets, eliminating the constraints of power cords, and greatly expanding the application scenarios of the device. This represents a significant improvement in the power supply method of the overall technical solution.

[0035] As one embodiment of this utility model, a charging interface 12 is provided on one side of the base plate 2, and the charging interface 12 is electrically connected to the battery 11.

[0036] On one side of the base plate 2, a charging interface 12 is further provided. This charging interface 12 is designed to connect an external power adapter or charging cable to charge the battery 11 built into the battery mounting compartment 10. The charging interface 12 is electrically connected to the charging management circuit of the battery 11 via internal wires.

[0037] As one embodiment of this utility model, the mounting clip 1 is a C-shaped clip structure; by using a C-shaped clip structure as the mounting clip 1, the device can be conveniently, quickly and stably clamped onto various support structures with edges, such as desktops, bookshelves, and workstation partitions.

[0038] As one embodiment of this utility model, a damping pad is provided on the surface of the rotating rod 17.

[0039] A mounting plate 6 is rotatably connected to the mounting groove 18 at the top of the base plate 2 via a rotating rod 17. To optimize the rotation performance of the mounting plate 6 on the rotating rod 17, a damping pad is provided on the surface of the rotating rod 17. The damping pad provides a certain resistance when the mounting plate 6 rotates, making the rotation process more stable and smooth, and avoiding problems such as free swaying or unstable positioning.

[0040] In one embodiment of this utility model, the mounting clip 1 is rotatably connected to the base plate 2 via a damping shaft.

[0041] By setting a damping pivot between the mounting clip 1 and the base plate 2, the rotation of the base plate 2 (and the entire fan assembly supported on it) relative to the mounting clip 1 is not free and unrestrained, but rather occurs under a certain damping effect. This allows the user to adjust the fan assembly to the desired angle and keep it stably at that angle, preventing positional changes due to its own weight or slight external contact, thus improving the positioning accuracy and stability of the device.

[0042] Working principle of this utility model:

[0043] In use, the easily adjustable fan can be fixed to the edge of a desktop or workstation partition using the mounting clip 1. When the entire fan assembly needs to be mounted on the workstation partition, the mounting clip 1 can be clamped to the edge of the partition, with the base plate 2 located on one side of the partition. At this time, by rotating the mounting plate 6, the gooseneck tube 3 and the fan body 16 on it can be rotated around the rotating rod 17 within the mounting groove 18, thus rotating the entire fan assembly above the partition. After rotation, the mounting plate 6 can be fixed (e.g., using bolts). Subsequently, the two gooseneck tubes 3 can be bent separately to make initial adjustments to the position and direction of the two fan bodies 16. Finally, by rotating the ball joint 4 at the bottom of the fan body 16 within the ball joint 5 at the top of the gooseneck tube 3, the blowing angle of the fan body 16 can be finely adjusted to precisely align with the two users. In this process, the mounting clip 1 and the base plate 2 provide a stable mounting foundation; the rotating connection structure of the mounting groove 18, the rotating rod 17 and the mounting plate 6 allows the fan body 16 to adapt to special installation environments such as partitions and achieve positional offset; the two gooseneck tubes 3 provide independent and malleable support, allowing for a wide range of positional adjustments to the two fan bodies 16; and the spherical joint formed by the spherical connector 4 and the spherical mounting base 5 provides flexible and precise angle adjustment capabilities.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
