Description

Technical Field

[0001] This utility model belongs to the field of fan technology, specifically relating to a storage structure for a floor fan. Background Technology

[0002] In the field of floor fans, the design of the column tube storage structure has always been a key factor affecting product portability and user experience. Current technologies for floor fan column tube storage structures often have significant defects: First, the fit between the storage groove and the column tube's contour is insufficient, preventing the column tube from fitting snugly against the base during storage. This results in poor storage stability and makes the column tube prone to detaching during transport due to shaking. Second, traditional snap-fit ​​structures often use a single-sided, single-point fixing method, offering limited axial limiting and cumbersome operation, requiring users to repeatedly adjust the tube for storage, severely impacting ease of use. Third, existing base storage structures lack a dedicated tube removal assist design, making it difficult to quickly remove the column tube after insertion into the storage groove, especially as the snaps age over time. Fourth, some floor fan bases directly contact the ground without support pads, making the base susceptible to moisture and wear during storage, and allowing debris from the ground to enter the storage groove, affecting the installation accuracy of the column tube. Summary of the Invention

[0003] The purpose of this invention is to provide a storage structure for a floor fan to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a floor fan storage structure, including a fan base and a fan upright tube, wherein the fan base is provided with a storage groove that matches the outline of the outer wall of the fan upright tube, and the storage groove is used to tightly fit and store the fan upright tube and the fan base.

[0005] The storage groove has at least two symmetrically distributed elastic buckles on its two side walls. These elastic buckles restrict the axial movement of the fan riser by engaging, thus keeping the fan riser secure in its stored state. The shape of the storage groove matches the outer wall contour of the fan riser.

[0006] Preferably, there are at least two elastic buckles, which are diagonally distributed on both sides of the storage groove. The storage groove has symmetrical buckle buffer grooves on its inner side. The elastic buckles are elastically set inside the buckle buffer grooves. The upper surface of the elastic buckle has a sliding inclined surface that allows the fan riser to be pressed into the storage groove and move outward elastically. The bottom side of the sliding inclined surface has an arc-shaped locking surface that allows the fan riser to spring back and fit tightly against the two sides of the fan riser after being inserted into the storage groove.

[0007] Preferably, the fan base has support pads evenly distributed on the lower end face side, which are used to maintain a distance between the fan base and the ground. The lower end face of the fan base has a remote control storage slot for storing the remote control in the inner cavity, and the upper end face of the fan base has a magnetic sheet inside the remote control storage slot for magnetic adsorption when the floor fan is placed on the surface of the fan base.

[0008] Preferably, each of the outer sides of one end of the storage groove is provided with a tube-retrieving groove, which is used to retrieve and place the fan tube from the storage groove.

[0009] Preferably, one end of each fan riser is an external connecting thread and the other end is an internal thread. The fan riser is connected to the internal thread end by screwing the external connecting thread end. One of the fan risers is installed in the internal thread groove provided at the center of the end of the fan chassis seat by the external connecting thread end.

[0010] Preferably, the fan riser assembly forms a support pole structure for the floor fan, and the upper end of the support pole structure is provided with a fan control body for controlling the operation of the fan, and the upper end of the fan control body is detachably connected to the fan head.

[0011] Preferably, the fan head includes a connector that is movably hinged to the upper end of the fan control body, and a motor rear housing is covered on the connector. A synchronous motor is installed inside the motor rear housing via a motor bracket.

[0012] Preferably, a drive motor is mounted on one side of the motor bracket, and a front housing is provided on one side of the drive motor shaft. A fan guard is provided on one side of the front housing, and a fan blade is provided inside the fan guard, which is sleeved and fixed to the drive motor shaft to drive it to rotate.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, the shape of the storage groove perfectly matches the outer contour of the fan riser tube, ensuring a tight fit between the riser tube and the chassis. This structurally avoids the wobbling and detachment problems caused by mismatched contours in existing technologies. Simultaneously, at least two diagonally distributed elastic buckles are provided on both sides of the storage groove, forming a bidirectional axial restraint through engagement. Compared to traditional single-sided, single-point fixing buckle structures, this not only provides higher fixing strength but also allows for quick insertion and removal of the riser tube, solving the problem of cumbersome operation and improving storage convenience.

[0015] This utility model uses an integrally formed support pad on the lower end face of the fan chassis to maintain a certain distance between the chassis and the ground, structurally blocking the direct erosion of the chassis by ground moisture, and preventing ground debris from entering the storage groove. This solves the problems of easy wear of the chassis and the impact of debris accumulation on the installation accuracy of the riser in the storage groove in the prior art, and extends the service life of the storage structure.

[0016] This utility model features a tube-removal groove on the outer side of one end of the storage recess. Through meticulous structural design, it provides users with a leverage point, facilitating quick removal of the fan riser tube even when it is stored. This design overcomes the difficulty in removing the riser tube caused by the lack of a tube-removal auxiliary structure in existing technologies. It also ensures smooth tube removal, especially when the clips wear out, thus improving user convenience. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a storage structure for a floor fan, wherein the fan base 1 is integrally injection molded from high-strength engineering plastic, possessing good impact resistance and wear resistance. The inner wall surface of the storage groove 3 is frosted, ensuring a tight fit with the outer contour of the fan upright 2 while increasing friction to prevent the upright from sliding during storage. The storage groove 3 is used to tightly fit and store the fan upright 2 and the fan base 1, significantly reducing the space occupied by the fan when not in use.

[0024] The counterweight embedded at the end of the fan base 1 is made of high-density cast iron, which provides stable support for the floor fan during operation and effectively prevents the fan from shaking. The upper cover of the fan base 1 is designed with a snap-on mechanism, which is easy to disassemble and install, and forms a smooth surface after installation, which is both aesthetically pleasing and prevents dust from entering the interior of the base. The fan base 1 has a remote control storage slot 16 on one side of its lower end face for storing the remote control in the inner cavity. The remote control storage slot 16 is located in the space between the storage grooves 3 and is flush with one end of the storage grooves 3. The upper end face of the fan base 1 has a magnetic piece inside corresponding to the remote control storage slot 16. When the floor fan is in use, the magnetic piece is placed on the surface of the fan base 1 and magnetically attracted. The magnetic piece is a neodymium iron boron permanent magnet with strong magnetic force. When the floor fan is in use, the remote control is magnetically attracted to the surface of the shell on the upper end face of the fan base 1 by the attraction of the magnetic piece, which prevents the remote control from being lost during use. When the floor fan is not in use, the remote control can be stored in the remote control storage slot 16 on the lower end face of the fan base 1. The storage method is embedded storage. In order to accurately attach the remote control to the position with the magnetic piece when the floor fan is in use, a silk screen mark can be set on the surface of the shell on the upper end face of the fan base 1 to ensure that the remote control is accurately magnetically fixed when the floor fan is in use.

[0025] The storage groove 3 has symmetrically provided buckle buffer grooves 4a on its inner side. The elastic buckle 4 is elastically set inside the buckle buffer groove 4a. The upper surface of the elastic buckle 4 is provided with a sliding inclined surface 4b that allows the fan riser tube 2 to be pressed into the storage groove 3 and move outward elastically. The bottom side of the sliding inclined surface 4b is provided with an arc-shaped locking surface 4c that allows the fan riser tube 2 to be snapped into the storage groove 3 and then spring back to fit against the two sides of the fan riser tube 2.

[0026] When the fan riser tube 2 begins to retract, the user holds the riser tube and aligns it with the storage groove 3, aligning the riser tube axis with the groove axis. At this time, the elastic buckle 4 is in its initial state. Due to the pre-compression allowance during assembly, the silicone buckle protrudes slightly outward and slides into the top of the inclined surface 4b, first contacting the outer wall of the fan riser tube 2.

[0027] As the user applies pressure, the outer wall of the riser slides downwards along the 35° inclined sliding surface 4b. Because the surface of the sliding surface 4b is treated with a nano-coating, the frictional resistance between the fan riser 2 and the elastic clip 4 is significantly reduced, resulting in a smooth and seamless pressing process. During this process, the elastic clip 4 is compressed by the riser, contracting inwards and undergoing elastic deformation within the clip buffer groove 4a. The inner layer of the groove, made of highly elastic TPE soft rubber, provides cushioning, while the outer layer of ABS plastic limits excessive deformation, ensuring structural safety.

[0028] As the riser slides down to the bottom of the inclined plane 4b, its outer wall just reaches the position of the curved locking surface 4c. At this moment, the elastic buckle 4, due to the rebound force of the silicone material, quickly returns to its original position, causing the curved locking surface 4c to fit tightly against both sides of the riser. The radius of the arc of the curved locking surface 4c precisely matches the cylindrical outer wall of the riser, and the 1mm interval of the surface micro-convex anti-slip texture increases the contact friction. Combined with the clamping force of 20N and the magnetic attraction of the magnet, the riser is firmly fixed in the storage groove 3.

[0029] The storage recess 3 has at least two symmetrically distributed elastic clips 4 on both side walls. These clips are made of highly elastic silicone and feature an embedded metal frame for enhanced toughness and durability. The elastic clips 4 restrict the axial movement of the fan riser 2 through an engaging mechanism. In the retracted state, the clips tightly engage with the riser surface, ensuring the fan riser 2 remains secure even under slight impact. The shape of the storage recess 3 matches the outer contour of the fan riser 2; this customized design makes storage more compact and stable. The at least two elastic clips 4 are diagonally distributed on both side walls of the storage recess 3. This arrangement constrains the fan riser 2 from multiple angles, further improving storage stability.

[0030] The fan base 1 has evenly spaced support pads 5 on the lower side of its side surface for stable support of the fan. These pads are made of non-slip rubber and have a fine wave pattern on their surface. This not only keeps the fan base 1 at a distance from the ground, effectively preventing the base from getting damp and damaged, but also increases the friction with the ground, preventing the fan from shifting during use.

[0031] Each end of the storage groove 3 has a tube-removing groove 6 on its outer side. The tube-removing groove 6 is arc-shaped, which makes it easy for users to insert their fingers and easily remove and place the fan tube 2 from the storage groove 3, avoiding scratches on the surface of the tube due to inconvenience in removing the tube.

[0032] Each fan riser tube 2 is made of high-strength aluminum alloy and is precision machined. One end has an external thread, and the other end has an internal thread. The fan riser tube 2 is connected to the internal thread end by screwing the external thread end into the internal thread end. The threaded connection is treated to prevent loosening, ensuring a firm and reliable connection. One of the fan riser tubes 2 is installed in the internal thread groove located at the center of the end of the fan base 1 through the external thread end. The inner wall of the internal thread groove has an anti-slip coating to further enhance the connection stability.

[0033] The fan stand 2 assembly forms the support structure for the floor fan, with its height optimized for ergonomic use. The upper part of the support structure houses the fan control unit 7, which controls the fan's operation. The fan control unit 7's housing is made of flame-retardant ABS material, providing excellent insulation and safety. One side of the fan control unit 7 features a display window and control panel for operating the floor fan. The display window uses a high-definition LCD screen for clear visuals, and the control panel buttons are made of silicone, offering a comfortable touch and waterproof / dustproof functionality. The fan head 8 is detachably connected to the upper part of the fan control unit 7 via a rotating clip, facilitating easy disassembly, cleaning, and maintenance of the fan head 8.

[0034] The connector 9 of the fan head 8 is hinged to the upper end of the fan control body 7 via a precision hinge shaft. A wear-resistant bearing is installed at the hinge shaft to ensure flexible rotation and a long service life for the connector 9. The motor housing 10, which covers the connector 9, can be made of lightweight, high-strength magnesium-aluminum alloy with an anodized surface, providing excellent corrosion resistance and aesthetics. Inside the motor housing 10, a synchronous motor 11 is mounted via a motor bracket. The motor bracket uses a composite structure combining high-strength plastic and metal, ensuring both stable motor mounting and effective noise reduction.

[0035] The crank, which is movably connected to the bottom of the shaft of the synchronous motor 11, undergoes a special heat treatment process to enhance its strength and wear resistance. A drive connector is movably connected to a raised cylinder on one side of the bottom of the crank. This connector adopts a high-precision ball joint structure to ensure accurate and smooth power transmission during the transmission process.

[0036] The drive motor 12, mounted on one side of the motor bracket, is a high-performance brushless DC motor, characterized by high efficiency, energy saving, and stable operation. The metal support rod fixed to the bottom of the drive motor 12 is connected to the motor body via precision welding to ensure connection strength. The positioning sleeve at the bottom of the metal support rod is made of polytetrafluoroethylene (PTFE), which has good self-lubricating properties and wear resistance.

[0037] The bottom end of the positioning sleeve is fitted onto a limiting post on one side of the upper end of the connector 9. The fitting clearance between the limiting post and the positioning sleeve is precisely calculated to ensure the flexible swing of the fan head 8 while preventing wobbling during the swing. A limiting post is provided on the outer side of the positioning sleeve, which is movably connected to the connecting rod. This limiting post is used to limit the swing angle of the drive motor 12, ensuring that the swing range of the fan head 8 meets the design requirements, while preventing damage to components due to excessive swing.

[0038] The circuit board bracket fixed inside the motor rear housing 10 is made of high-strength insulating plastic, providing excellent electrical insulation performance. The circuit board bracket houses a control circuit board for controlling the synchronous motor 11 and the drive motor 12. This control circuit board employs a multi-layer wiring design, offering high integration and stability, and is effectively shielded to prevent electromagnetic interference. The control circuit board is electrically connected to the display control panel, enabling users to precisely control various fan functions via the control panel.

[0039] The motor front housing 13, located on one side of the drive motor 12 shaft, features a streamlined design that is not only aesthetically pleasing but also effectively reduces wind resistance. A fan grille 14, also located on one side of the motor front housing 13, comprises a front grille and a rear grille, both made of high-strength ABS plastic. The rear grille is positioned and fixed to one side of the motor front housing 13 via multiple positioning posts and secured with plastic nuts after installation. This fixing method facilitates disassembly and cleaning of the grille.

[0040] The shaft of the drive motor 12 passes through the front housing 13 and extends into the rear grille. A high-strength limiting rod is attached to the motor shaft, which limits and fixes the fan blade 15 after it enters the motor, preventing the fan blade 15 from moving axially. The suction cap locked on the motor shaft is made of high-strength engineering plastic and has a rubber sealing ring inside. It is used to press the fan blade 15 firmly against the synchronous motor 11, keeping the fan blade 15 stable and secure during rotation, while preventing dust from entering the motor and ensuring the reliability and safety of the fan operation.

[0041] The synchronous motor 11 adopts a closed-loop control method, receiving a PWM (Pulse Width Modulation) signal from the control circuit board. This signal can precisely adjust the motor's speed and direction, achieving uniform oscillation of the fan head 8 within an angle range of 60°-120°. The motor has a rated power of 15W and a starting torque of 0.8N・m, and can quickly reach the set speed within 2 seconds, ensuring smooth and stable fan oscillation. It also has an overload protection function; when the motor load exceeds 120% of the rated value, the control circuit board will automatically cut off the power supply to prevent the motor from overheating and being damaged.

[0042] The drive motor 12 is equipped with a Hall sensor to monitor the rotor position in real time and receive frequency conversion speed control signals from the control circuit board, enabling five levels of fan speed adjustment, corresponding to a power range of 25W to 50W. At the lowest power setting of 25W, the fan blade 15 rotates at 800 rpm, producing a gentle, natural breeze; at the highest power setting of 50W, the speed increases to 1500 rpm, with a maximum airflow of 30 m³ / min. The motor also has a built-in current feedback module that transmits operating current data back to the control circuit board in real time for dynamic adjustment of output power, ensuring effective air delivery while reducing energy consumption and improving energy efficiency.

[0043] Specifically, in use, the storage structure consists of a fan base 1 and a fan riser 2. The fan base 1 has a storage groove 3 that matches the outer contour of the fan riser 2. Elastic buckles 4 are distributed diagonally on both sides of the groove to fix the fan riser 2 axially. The fan base 1 has an embedded counterweight to enhance stability, and a support pad 5 is provided on the lower end to prevent moisture. A magnet is embedded in the surface to magnetically fix the accessories. One end of the storage groove 3 has a tube-removal groove 6 to facilitate the removal and placement of the fan riser 2. The two fan risers 2 are connected by threads to form a support rod, and the upper end is connected to the fan control body 7 and the fan head 8.

[0044] The working principle of the floor fan: The counterweight and support pad 5 of the fan base 1 lower the center of gravity, ensuring fan stability; the drive motor 12 drives the fan blades 15 to rotate, generating airflow, which is guided out by the fan grille 14. The synchronous motor 11 drives the fan head 8 to oscillate left and right through a crank-connecting rod mechanism, and the positioning sleeve and limit column limit the oscillation angle. The user inputs commands through the display panel of the fan control unit 7, and the control circuit board processes the signals and adjusts the speed of the drive motor 12 and the operation of the synchronous motor 11 to achieve wind speed and oscillation mode control.

[0045] The disassembly, assembly, and storage process for fan riser 2: When disassembling, unscrew the threaded connection between fan riser 2 and fan base 1; the metal parts will be attracted to the magnet on fan base 1. When storing, place fan riser 2 into storage groove 3; the elastic clip 4 will automatically engage and secure it. Then, close the top cover of fan base 1. To remove, insert your finger into the tube extraction groove 6 and pull out fan riser 2. Then, reassemble fan riser 2 onto fan base 1 using the threads to restore the overall structure.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
