Description

Technical Field

[0001] This utility model belongs to the field of home appliance technology, and specifically relates to a fan. Background Technology

[0002] With the improvement of people's living standards and the diversification of living environments, the functional needs of electric fans, as commonly used ventilation and cooling devices in daily life, are becoming increasingly diversified. Traditional electric fans are mostly fixed types, such as floor fans or table fans. Floor fans usually have tall stands and a large airflow range, suitable for larger spaces such as living rooms and offices; while table fans are smaller and placed on desktops or bedside tables, suitable for short-distance localized airflow. However, these two types of fans have limited functions and cannot meet the needs of different usage scenarios, resulting in users needing to purchase multiple fans at the same time, increasing usage costs and storage burden.

[0003] To enhance product versatility, detachable fan designs have emerged in recent years, separating the fan body from the base. This allows the fan to be used on the floor or as a portable desk fan by removing the fan head. This design improves the product's flexibility to some extent. However, existing detachable fans often lack a stable and reliable support structure when used as desk fans. Some products use conventional tripods, but these structures still occupy a significant amount of space when folded, resulting in a bulky overall size and poor portability.

[0004] Therefore, how to design a fan that can freely switch between floor fan and table fan functions, and also has the advantages of compact structure, stable support, and convenient assembly and disassembly, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a fan.

[0006] The objective of this utility model can be achieved through the following technical solution: a fan, comprising:

[0007] Base;

[0008] The fan body is detachably connected to the base, and a support frame is provided at the bottom of the fan body;

[0009] During the process of the support frame moving from a retracted state to an extended state after the fan body is separated from the base, the support frame first rotates around a first axis and then around a second axis.

[0010] As a further improvement of this utility model, the support frame includes a first bracket and two second brackets. A first rotating shaft is provided at the bottom of the fan body. The first rotating shaft defines the first axis. The first bracket is rotatably connected to the bottom of the fan body through the first rotating shaft. Two adjacent second rotating shafts are provided on the first bracket. The second rotating shaft defines the second axis. The second bracket is rotatably connected to the first bracket through the second rotating shaft.

[0011] As a further improvement of this utility model, the first axis is set as a horizontal axis, the second axis is set as a vertical axis, and the two second supports rotate in opposite directions during the rotation of the two second supports around the corresponding second rotating axis.

[0012] As a further improvement of this utility model, the second bracket is provided with a groove. When the support frame is in the retracted state, the first bracket is received in the groove of the two second brackets. When the support frame is in the extended state, the first bracket and the two second brackets are in the horizontal plane.

[0013] As a further improvement of this utility model, the fan body includes a fan head, a support arm, and a rotating base. One end of the support arm is connected to the fan head, and the other end of the support arm is connected to the rotating base. The support frame is disposed at the bottom of the rotating base.

[0014] As a further improvement of this utility model, the bottom of the rotating seat is provided with a connecting groove, the base is provided with a connecting part, the connecting part is inserted into the connecting groove, the side of the rotating seat is provided with a lock hole, the connecting part is provided with an unlock button, the unlock button is retractably provided on the connecting part, and the unlock button is inserted into the lock hole.

[0015] As a further improvement of this utility model, a reset component is provided on the inner side of the unlock button, the side wall of the unlock button extends downward to form a hook, a locking block is provided on the connecting part, a slot is provided on the locking block, and the hook engages with the slot.

[0016] As a further improvement of this utility model, the fan head includes an outer shell, an inner shell, a motor, a control board, and a battery. The inner shell is connected to the outer shell, and an accommodating space is provided in the inner shell. The motor, the control board, and the battery are all disposed in the accommodating space.

[0017] As a further improvement of this utility model, a handle assembly is provided on the outer shell of the fan body. The handle assembly includes a handle and a guide pin. The handle includes a carrying part and a limiting part connected to each other. The limiting part is provided at both ends of the carrying part. The carrying part and the limiting part are respectively provided on the inner and outer sides of the outer shell. A guide hole is provided on the limiting part. The guide pin is inserted into the guide hole and fixedly connected to the outer shell.

[0018] As a further improvement of this utility model, the handle assembly also includes an elastic element, one end of which is connected to the connecting part, and the other end of which is fixedly connected to the outer shell.

[0019] Based on the above technical solution, this utility model can produce at least the following technical effects:

[0020] 1. By setting the support frame to rotate sequentially around the first axis and the second axis during the unfolding process, a two-step unfolding structure is achieved, making the support frame more compact in the folded state, reducing the overall volume, and making it easier to carry and store. At the same time, this two-step unfolding method improves the stability of the support structure, providing reliable support force after unfolding to ensure the stability and safety of the fan body when used as a table fan.

[0021] 2. The first bracket acts as an intermediate connector, driving the two second brackets to unfold in tandem, forming a stable triangular support structure. The connection between the first bracket and the fan body provides the initial unfolding action, while the second bracket completes the final unfolding positioning through the second rotating shaft, achieving step-by-step control. The structure is compact, and the unfolding process is smooth and reliable.

[0022] 3. By setting grooves on the second bracket to accommodate the first bracket, the components of the support frame fit together tightly in the folded state, significantly reducing the space occupied, making the appearance neat and beautiful, and easy to store and carry; while in the unfolded state, the first bracket and the two second brackets are together in the horizontal plane, forming a stable planar support structure, effectively distributing the force, and improving the uniformity of support and overall stability.

[0023] 4. Through the plug-in connection between the connecting slot and the connecting part, along with the locking structure of the unlock button and the lock hole, quick assembly and disassembly of the fan body and the base are achieved, ensuring a secure connection. Users can easily disassemble the fan body by simply pressing the unlock button, making the operation simple and quick, and improving the product's detachability and flexibility of use.

[0024] 5. By integrating the motor, control board, and battery into the inner casing, the core components are highly integrated and effectively protected, preventing external impacts on critical electronic components and extending the product's lifespan. Simultaneously, the built-in battery design allows the fan to operate independently even after detaching from the base, truly realizing a portable table fan function without external power. This broadens its application scenarios, making it particularly suitable for outdoor, bedside, and desk environments without power outlets.

[0025] 6. The handle assembly greatly enhances the portability of the fan body, allowing users to easily grasp the handle to move or carry the fan. The elastic element provides an automatic return function, allowing the handle to automatically return to its folded position when not lifted, maintaining a neat appearance.

In this utility model, unless otherwise explicitly specified and defined, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances. Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0036] The following are specific embodiments of this utility model, in conjunction with the accompanying drawings. Figure 1-8 The technical solution of this utility model will be further described below, but this utility model is not limited to the following embodiments.

[0037] This utility model provides a fan that can be used as a floor fan, and the fan body can be detached from the base 100 and used independently as a table fan, realizing multiple uses and meeting the air supply needs in different scenarios.

[0038] The fan includes a base 100 and a fan body, which are detachably connected to the base 100, allowing users to freely switch between usage modes as needed. When the fan body is mounted on the base 100, it forms a floor fan suitable for wide-area airflow; when the fan body is removed from the base 100, it can be independently supported on a desktop, bedside table, or other flat surface using the support frame 500 at its bottom, and used as a portable table fan.

[0039] The support frame 500 is located at the bottom of the fan body and is in a folded state when not in use, making it easy to carry and store. When needed for use as a table fan, the user unfolds the support frame 500 from the folded state to the unfolded state. During the unfolding process, the support frame 500 first rotates around the first axis A, and then around the second axis B, forming a two-step unfolding structure. This design ensures that the support frame 500 moves in an orderly and smooth manner during unfolding, while significantly improving the space utilization when folded.

[0040] Furthermore, the first axis A is set as a horizontal axis, and the second axis B is set as a vertical axis. The first axis A and the second axis B are perpendicular to each other, so that when the support frame 500 changes from a vertically retracted state to a horizontally extended state, the movement trajectory is reasonable, the structural interference is small, and the operation is smoother.

[0041] The support frame 500 includes a first bracket 510 and two second brackets 520. A first rotating shaft 410 is located at the bottom of the fan body, defining a first axis A. The first bracket 510 is rotatably connected to the fan body via the first rotating shaft 410, achieving the first step of deployment. Two adjacent second rotating shafts 511 are located on the first bracket 510, defining a second axis B. The two second brackets 520 are rotatably connected to the first bracket 510 via their respective second rotating shafts 511, achieving the second step of deployment. During rotation around their respective second rotating shafts 511, the two second brackets 520 rotate in opposite directions.

[0042] Preferably, the second bracket 520 is provided with a groove 521. When the support frame 500 is in the retracted state, the first bracket 510 is embedded in the grooves 521 of the two second brackets 520, realizing nested storage between components. The structure is highly compact and the overall shape is flat, making it easy to carry. When the support frame 500 is fully extended, the first bracket 510 and the two second brackets 520 are all on the same horizontal plane, forming a stable triangular support structure, ensuring that the fan body is placed stably and is not easy to tip over.

[0043] The fan body includes a fan head 200, a support arm 300, and a rotating base 400. One end of the support arm 300 is connected to the fan head 200, and the other end is connected to the rotating base 400. The rotating base 400 can be angled relative to the support arm 300 to adjust the airflow direction. A support frame 500 is located at the bottom of the rotating base 400.

[0044] Furthermore, to facilitate quick assembly and disassembly of the fan body and the base 100, the bottom of the rotating base 400 is provided with a connecting groove 420, and the base 100 is provided with a matching connecting part 110. During connection, inserting the connecting part 110 into the connecting groove 420 completes the initial positioning. To prevent accidental detachment during use, the side of the rotating base 400 is provided with a locking hole 430, and the connecting part 110 is provided with a retractable unlocking button 120. Inserting the unlocking button 120 into the locking hole 430 locks the fan in place.

[0045] Furthermore, the unlock button 120 has a reset element 121 on its inner side. In this embodiment, the reset element 121 is a compression spring. The side wall of the unlock button 120 extends downward to form a hook 122. The connecting part 110 has a locking block 130, and the locking block 130 has a slot 131. The hook 122 engages with the slot 131. When the connecting part 110 is inserted into place, the unlock button 120 is inserted into the lock hole 430, and at the same time, the hook 122 engages with the slot 131 to achieve locking. When disassembly is required, the user presses the unlock button 120 to disengage it from the lock hole 430, and the fan body can be removed from the base 100. The operation is simple and the connection is reliable.

[0046] The fan head 200 includes a housing 210, an inner housing 220, a motor 221, a control board 222, and a battery 223. The inner housing 220 is fixed inside the housing 210, forming a closed receiving space, within which the motor 221, control board 222, and battery 223 are all housed. The battery 223 provides an independent power source for the fan, allowing it to continue operating even after being detached from the base 100, truly achieving portable use without an external power source.

[0047] In addition, the fan body housing 210 is equipped with a handle 211 assembly for easy carrying. The handle 211 assembly includes a handle 211 and a guide pin 212. The handle 211 includes a carrying part and limiting parts located at both ends, which are located on the inner and outer sides of the housing 210, respectively. The limiting parts are provided with guide holes, through which the guide pin 212 passes and is fixedly connected to the housing 210, enabling the handle 211 to be slidably installed.

[0048] Preferably, the handle 211 assembly further includes an elastic element 213, one end of which is connected to the limiting part, and the other end is fixed to the housing 210. When the user releases the handle 211, the elastic element 213 causes the handle 211 to automatically return to the storage position, maintaining a neat appearance and avoiding protrusions and bumps.

[0049] The operation of this fan is as follows: When using it in the living room, the fan body is installed on the base 100 as a floor fan; when it needs to be used at the bedside in the bedroom, the unlock button 120 is pressed to remove the fan body, unfold the bottom support frame 500, and it can be used as a table fan independently. The whole process is simple to operate and the function switching is flexible.

[0050] In summary, this utility model, through its two-step unfolding support frame 500 structure, detachable connection mechanism, built-in battery 223, and handle 211 design, enables the fan to freely switch between a floor fan and a table fan. It has the advantages of compact structure, stable support, convenient carrying, and flexible use, significantly improving the user experience.

[0051] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
