[0054] To explain in detail the technical content, technical steps, objectives and effects of this application, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0055] With the increasing popularity of outdoor activities, portable fans have become an important tool for people during outdoor leisure time. Current portable fans are typically designed with relatively simple power supply and control systems, making it difficult to meet the needs of prolonged use or control in specific environments. Therefore, improving the ease of use and power supply controllability of portable fans has become an urgent problem to be solved.

[0056] This utility model provides a portable outdoor fan 10. Please refer to [link / reference]. Figures 1 to 5 The portable outdoor fan 10 includes a fan head 100 and a control assembly 200 detachably mounted on the fan head 100.

[0057] For fan head 100, such as Figure 2As shown, the fan head 100 includes a mounting frame 110 and a fan blade assembly 120 disposed within the mounting frame 110. The mounting frame 110 is a cylindrical frame structure and is fixedly mounted on the swing mechanism 300 of the portable outdoor fan 10. The fan blade assembly 120 is concentrically disposed within the mounting frame 110.

[0058] Specifically, such as Figure 3 As shown, the fan blade assembly 120 includes a motor and fan blades mounted on the motor. The motor can be a stepper motor, which does not occupy space and is more energy-efficient. The fan blade assembly 120 can be fixedly mounted on the mounting frame 110 by a clamp. The mounting frame 110 is a cylindrical frame, which is formed by combining a circular front grille 111, a cylindrical side grille 112, and a circular rear grille 113.

[0059] Furthermore, the circular front mesh cover 111 is detachably and fixedly connected to the front of the cylindrical side cover 112, and the circular rear mesh cover 113 is detachably and fixedly connected to the back of the cylindrical side cover 112. To reduce the obstruction of airflow caused by the control assembly 200 being located in the center of the circular front mesh cover 111, a guide vane 114 is provided inside the cylindrical side cover 112. When the airflow generated by the fan blows onto the guide vane 114, the guide vane 114 can direct the airflow to the circular rear mesh cover 113, reducing resistance to airflow outflow.

[0060] Understandably, the control component 200, the circular front grille 111, the fan blade assembly 120, the cylindrical side cover 112, the air guide 114, and the circular rear grille 113 are all mounted on the output shaft of the motor, and the fan blade assembly 120 is located between the circular front grille 111 and the circular rear grille 113.

[0061] Regarding the control component 200, it features convenient power supply and function control, and is easy to disassemble and replace. Specifically, such as... Figure 4 As shown, the control assembly 200 includes a rechargeable battery 210, a control panel 220, and a housing 230. The rechargeable battery 210 is disposed within the cavity 231 of the housing 230 and is used to power the portable outdoor fan 10. The control panel 220 is disposed within the cavity 231 of the housing 230 and is used to control the functions of the portable outdoor fan 10. The cavity 231 inside the housing 230 houses the rechargeable battery 210 and the control panel 220, and is detachably mounted on the fan head 100, so that the entire control assembly 200 can be detachably mounted on the fan head 100 along with the housing 230.

[0062] In some embodiments, the rechargeable battery 210 is the power source for the portable outdoor fan 10, providing power for the fan's various functions. This battery has the following characteristics: it is rechargeable, supports multiple cycles to reduce operating costs, and has overcharge and over-discharge protection functions to ensure safe and reliable use.

[0063] In some embodiments, the control panel 220 is used to control various functions of the portable outdoor fan 10, specifically including switch control. Users can turn the fan on or off and adjust the fan speed through the control panel 220. Users can adjust the fan speed according to their needs to achieve different user experiences. The timer function can be set to set the working time of the fan to facilitate energy saving.

[0064] In some embodiments, continue as follows Figure 4 As shown, the control panel 220 includes a knob cover 221 and a control board 222. The user can rotate the knob cover 221 to the corresponding position and the control board 222 receives the corresponding control command for that position to set the on / off control, wind speed adjustment, or working time of the portable outdoor fan 10, thereby controlling the operation of the portable outdoor fan 10.

[0065] In some embodiments, the housing 230 is used to house the rechargeable battery 210 and the control panel 220, and has the following features: a detachable design, allowing users to easily remove the housing 230 to replace the rechargeable battery 210 or the control panel 220 to address insufficient power or malfunction issues; and a robust structure, with the housing 230 protecting the internal components from external environmental influences.

[0066] In a specific application scenario, when the portable outdoor fan 10 is working normally, the rechargeable battery 210 supplies power to the fan head 100 via the control panel 220, causing the fan blades of the fan head 100 to rotate and provide cool air. Users can perform various operations through the control panel 220, such as adjusting the wind speed and setting a timer.

[0067] In one embodiment, when the rechargeable battery 210 is depleted and / or the control panel 220 is faulty, the user can replace the control component 200 by removing the housing 230 from the fan head 100.

[0068] Specifically, in the following situations, users can perform fan maintenance by disassembling the housing 230: ① When the rechargeable battery 210 is low: When the fan indicates low battery or fails to start normally, the user can remove the housing 230 to take out the entire control component 200 and replace it with a new one. ② When the control panel 220 malfunctions and cannot operate normally, the user can remove the housing 230 to take out the entire control component 200 and replace it with a new one, thereby restoring the fan's normal function.

[0069] The technical advantages of the above solution are as follows: Through innovative design of the control components, it makes power supply and functional control more user-friendly and convenient, overcoming several shortcomings of existing technologies. Specifically, users can easily disassemble and reassemble the casing for maintenance, greatly improving the ease of use and maintainability of the portable outdoor fan. Furthermore, the integration of the rechargeable battery and control panel supports multi-functional control, meeting diverse user needs. Finally, the reusable rechargeable battery makes the device more economical and environmentally friendly in use.

[0070] In one embodiment, such as Figure 1 As shown, the portable outdoor fan 10 provided by this utility model also includes a swing mechanism 300 and a base 400 that are configured and connected to each other.

[0071] For the base 400, such as Figure 1 As shown, by setting the base 400, the fan body of the portable outdoor fan 10 can be placed on a flat surface for use. The base 400 can be a spatial structure in the form of a frustum, a rectangular frustum, a cylinder, etc. This application does not make any specific limitation here.

[0072] In some embodiments, such as Figure 5 As shown, on the back side of the portable outdoor fan 10, the surface of the base 400 is provided with an interface groove 410. The interface groove 410 includes a first power input hole 411 and a second power input hole 412. The first power input hole 411 and the second power input hole 412 can be connected to a charging power supply or other devices via a data cable to directly power the portable outdoor fan 10, or the internal lithium battery can be charged through the first power input hole 411 or the second power input hole 412.

[0073] In some embodiments, the first power input port 411 is a "circular socket" that can be connected to a DC plug (direct current power plug) to connect to a DC power supply device. The second power input port 412 is a "flat socket" that can be connected to a USB plug or a Type-C plug to connect to a wide range of mobile devices such as power banks, mobile phones, tablets, and laptops, and supports reversible insertion and fast charging.

[0074] Regarding the oscillating mechanism 300, continue as follows Figure 1 As shown, the base 400 provides support for the swing mechanism 300 to make it stable, and the swing mechanism 300 is hinged to the base 400 to adjust the tilt angle of the fan head 100.

[0075] Specifically, such as Figure 2 As shown, the top edge of the base 400 is chamfered, and the top surface of the base 400 is provided with an upward-facing mounting groove 420. The swing mechanism 300 includes a turntable 310, and a vertically downward-extending rotating shaft 311 is provided at the bottom of the turntable 310. The rotating shaft 311 is rotatably installed in the mounting groove 420, so that the portable outdoor fan 10 can adjust the pitch angle or left and right angle of the fan head 100 through the rotating shaft 311, so as to adjust the air outlet angle of the fan head 100 together with the turntable 310 to improve the use effect.

[0076] In some embodiments, a damping washer 421 is provided between the outer wall of the rotating shaft 311 and the mounting groove 420. The damping washer 421 is used to increase the frictional resistance between the rotating shaft 311 and the mounting groove 420, so that the turntable 310 can maintain a stable angle after rotation. The damping washer 421 can be made of rubber to increase the frictional resistance when the rotating shaft 311 rotates, so that the adjusted fan head 100 can remain stable.

[0077] In another embodiment, a first magnetic element (not shown) may be fixed inside the base 400, and a second magnetic element (not shown) may be movably disposed at the bottom of the swing mechanism 300. The first magnetic element and the second magnetic element may be magnetically attracted to each other, and the fan head 100 may be fixedly connected to the swing mechanism 300.

[0078] Specifically, when using the portable outdoor fan 10, the oscillation mechanism 300 can be placed on the base 400. The oscillation mechanism 300 is fixed to the base 400 by the magnetic attraction between the first and second magnetic elements. During use of the portable outdoor fan 10, the angle of the oscillation mechanism 300 can be freely rotated. During rotation, the second magnetic element moves at the bottom of the oscillation mechanism 300 and always maintains a magnetic attraction with the first magnetic element. This magnetic attraction between the first and second magnetic elements stabilizes the fan head 100. By movably setting the second magnetic element, the user can freely rotate the angle of the fan head 100 as needed, and the base 400 always maintains a magnetic connection and support with the oscillation mechanism 300.

[0079] The technical advantages of the above solution are as follows: Firstly, the rechargeable battery ensures that the fan can be independently powered, meeting the needs of outdoor use. The control panel provides users with an intuitive interface for adjusting fan functions, and the detachable design of the casing allows users to quickly replace newly added control components. This design not only improves the ease of use of the fan but also effectively extends its service life and simplifies the installation of control components and other components. Secondly, by differentiating itself from existing technologies, this solution, through a rational structural design of the portable outdoor fan, simplifies the installation of control components and other components. Users can directly replace the battery when it is low, saving outdoor charging time and solving the battery life problem. Furthermore, since the control panel in the fan is a consumable component, integrating the control panel into the control component allows users to quickly replace the faulty control component when the control panel malfunctions, reducing interruptions caused by component failure and improving the user experience.

[0080] Those skilled in the art will understand that Figures 1 to 5 The portable outdoor fan shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the outdoor fan used in the present application. The specific control components may include more or fewer parts than those shown in the figure, or combine certain parts, or have different part arrangements.

[0081] In one embodiment, such as Figure 4 and Figure 6As shown, the outer casing 230 has a cylindrical structure and a snap-fit ​​groove 232 is provided on the circumferential side of the outer casing 230; and a cylindrical positioning groove 101 adapted to the structure of the outer casing 230 is provided on the fan head 100, and a snap-fit ​​block 102 adapted to the snap-fit ​​groove 232 is also provided in the cylindrical positioning groove 101; wherein, the outer casing 230 is placed into the cylindrical positioning groove 101, and the snap-fit ​​block 102 is fastened and fixed to the snap-fit ​​groove 232 by rotating the outer casing 230, so as to fix the control component 200 to the fan head 100.

[0082] Specifically, the outer casing 230 has a cylindrical structure, designed to improve overall stability. The cylindrical design effectively withstands external forces, reducing the risk of deformation or damage during use. A locking groove 232 is provided on the circumferential side of the outer casing 230, providing a convenient method for subsequent fixing. A cylindrical positioning groove 101, adapted to the structure of the outer casing 230, is provided on the fan head 100, perfectly fitting the casing 230 to form a closed connection. Furthermore, a locking block 102, adapted to the locking groove 232, is provided within the cylindrical positioning groove 101, providing a stable locking mechanism during fixing.

[0083] In some embodiments, during the process of fixing the control component 200 to the fan head 100, the user can insert the housing 230 into the cylindrical positioning groove 101 of the fan head 100. The operation steps are as follows: First, align the housing 230 with the cylindrical positioning groove 101, ensuring that the locking groove 232 and the locking block 102 are in relative positions. Then, the user gently rotates the housing 230, and the locking block 102 will penetrate into the locking groove 232, forming a tight connection. Finally, by rotating, the locking block 102 and the locking groove 232 are fastened and fixed, achieving a stable installation of the control component 200. This design ensures that the housing 230 will not loosen due to external force during use, while simplifying the disassembly and replacement process. The user only needs to rotate the housing 230 clockwise to complete the installation and rotate it counterclockwise to disassemble, bringing great convenience to the user.

[0084] The technical advantages of the above embodiments are as follows: the combination of the cylindrical structure and the swivel joint enhances the connection strength between the outer shell and the fan head, preventing loosening during use. At the same time, users can easily install and remove the outer shell with a simple rotation, improving the operability of the portable outdoor fan.

[0085] In one embodiment, such as Figure 7 and Figure 8As shown, a conductive spring pin 211 connected to the rechargeable battery 210 is provided on the side of the outer casing 230 facing the cylindrical positioning groove 101, and a conductive post 103 is provided at the position where the cylindrical positioning groove 101 matches the conductive spring pin 211; wherein, when the control component 200 is fixedly installed on the fan head 100, the conductive spring pin 211 and the conductive post 103 abut against each other to form a current path, so that the rechargeable battery 210 supplies power to the portable outdoor fan 10 through the current path.

[0086] Specifically, on one hand, a conductive spring pin 211 connected to the rechargeable battery 210 is provided on the side of the outer casing 230 facing the cylindrical positioning groove 101. The conductive spring pin 211 is designed to provide a reliable electrical connection to the rechargeable battery 210. The conductive spring pin 211 has a certain degree of elasticity, allowing it to adaptively adjust its position when it abuts against the conductive post 103, ensuring good electrical contact. On the other hand, a conductive post 103 is provided at the position where the cylindrical positioning groove 101 matches the conductive spring pin 211. The conductive post 103 is designed to form a stable contact point with the conductive spring pin 211, thereby establishing a current path. The conductive post 103 uses a high-quality conductive material to ensure efficient current conduction and reduce energy loss when contact is formed.

[0087] In some embodiments, during the assembly and use of the portable outdoor fan 10, after the user completes the installation of the housing 230, the conductive spring pin 211 and the conductive post 103 naturally come into contact, forming a current path. The working process includes: ① Installation process: When the user fixes the control component 200 to the fan head 100, the conductive spring pin 211 is pressed into the matching conductive post 103. ② Current formation: When the conductive spring pin 211 and the conductive post 103 come into contact, a conductive path is established, allowing current to flow smoothly from the rechargeable battery 210 to the fan motor and other components. ③ Continuous power supply: In operation, the rechargeable battery 210 stably provides power to the portable outdoor fan 10 through the current path, ensuring the fan operates normally and allowing the user to enjoy a cool airflow.

[0088] In other embodiments, the process continues as follows: Figure 7 As shown, a USB interface 212 for connecting to the rechargeable battery 210 is provided on the periphery of the housing 230. The USB interface 212 is used to charge the control component 200 when it is detached from the portable outdoor fan 10 for later use. Specifically, after the control component 200 is detached from the portable outdoor fan 10, the user can easily connect the USB interface 212 to a power device such as a USB power adapter or computer to charge the rechargeable battery 210. This design makes charging more flexible, no longer limited to a specific charger or charging method.

[0089] The technical advantages of the above embodiments are as follows: the complementary design of the conductive spring pin and the conductive post ensures reliable electrical contact and reduces power outages caused by poor contact. Furthermore, the elasticity of the conductive spring pin allows it to self-adjust during installation and subsequent use, enhancing overall applicability. This design simplifies the power connection process, allowing users to ensure smooth power supply to the fan without complex operations.

[0090] In one embodiment, the housing 230 also houses a power transmitting circuit device, connecting wires, and a power transmitting coil (not shown). The power transmitting circuit device converts the electrical energy of the rechargeable battery 210 into electromagnetic induction resonance, which is then transmitted to the power transmitting coil via the connecting wires, and the power transmitting coil transmits the electromagnetic induction resonance into space. The fan head 100 is provided with a power receiving circuit device and a power receiving coil (not shown). The power receiving coil receives the electromagnetic induction resonance transmitted into space by the power transmitting coil, and the power receiving circuit device converts the electromagnetic induction resonance received by the power receiving coil into electrical energy to power the portable outdoor fan 10.

[0091] In the aforementioned power supply method, unlike the conductive design that uses conductive pins and conductive posts, the power transmission of the rechargeable battery is achieved through the principle of electromagnetic induction, eliminating the need for physical connections and improving the portability and flexibility of the device.

[0092] Specifically, on one hand, an energy transmitting circuit is installed inside the housing 230. The main function of this device is to convert the electrical energy stored in the rechargeable battery 210 into an electromagnetic induction resonant signal to achieve wireless power supply. The energy transmitting circuit is connected to the energy transmitting coil via connecting wires so that the converted electrical energy can be effectively delivered to the coil. The energy transmitting coil is located inside the housing 230. Its function is to receive the electromagnetic induction resonant signal from the energy transmitting circuit and transmit it into the surrounding space. To improve the efficiency and distance of wireless power supply, the coil design requires the use of special conductive materials to enhance its electromagnetic transmission capability. On the other hand, an energy receiving circuit is installed in the fan head 100. Its main function is to receive the electrical energy emitted by electromagnetic induction and convert it into electrical energy usable by the fan. The energy receiving coil is connected to the energy receiving circuit and its function is to capture the electromagnetic induction resonance emitted by the energy transmitting coil, making full use of the electrical energy in the space.

[0093] In some embodiments, the wireless power supply structure of the portable outdoor fan 10 in this application includes the following operation steps: ① Power conversion: When the fan control component 200 is working normally, the rechargeable battery 210 begins to convert electrical energy into an electromagnetic induction resonant signal through the power transmission circuit device, and transmits it to the power transmission coil through the connecting wire. ② Power transmission: After receiving the converted electromagnetic signal, the power transmission coil transmits it into the surrounding space, forming an electromagnetic induction resonant field. ③ Power reception: The power receiving coil inside the fan head 100 operates in the electromagnetic field and captures the electromagnetic induction resonant signal transmitted from the transmission coil. ④ Power conversion: The power receiving circuit device converts the received electromagnetic signal into electrical energy and supplies it to the motor and other components of the portable outdoor fan 10 by adjusting the output, thereby achieving continuous power supply for the device.

[0094] The technical advantages of the above embodiments are as follows: Wireless power supply is achieved through electromagnetic induction, avoiding the cumbersome process of traditional battery replacement and the dependence on sockets for charging, thus improving usability. Furthermore, the design of the power transmitting circuit and receiving device improves power conversion efficiency, ensuring stable operation of the fan in various environments.

The control panel provides an intuitive interface for easy fan function adjustment, and the detachable casing allows for quick replacement of new control components. This design not only improves usability but also extends the fan's lifespan and simplifies the installation of control and other components. On the other hand, unlike existing technologies, this solution utilizes a rational structural design for the portable outdoor fan, simplifying the installation of control and other components. Users can directly swap batteries when the power is low, saving outdoor charging time and solving the battery life issue. Furthermore, since the control panel is a consumable component, integrating it into the control unit allows for quick replacement of faulty components in case of control panel malfunction, reducing interruptions caused by component failure and improving user experience.

[0111] With the increasing popularity of outdoor activities, portable fans have become an important tool for people during outdoor leisure time. Current portable fans are typically designed with relatively simple power supply and control systems, making it difficult to meet the needs of prolonged use or control in specific environments.

[0118] In some embodiments, a damping washer 421 is provided between the outer wall of the rotating shaft 311” and the mounting groove 420”. The damping washer 421” is used to increase the frictional resistance between the rotating shaft 311” and the mounting groove 420”, so that the turntable 310” can maintain a stable angle after rotation. The damping washer 421” can be made of rubber material to increase the frictional resistance when the rotating shaft 311” rotates, so that the adjusted fan head 100” can remain stable.

[0119] In another embodiment, a first magnetic element (not shown) may be fixed inside the base 400”, and a second magnetic element (not shown) may be movably provided at the bottom of the swing mechanism 300”. The first magnetic element and the second magnetic element may be magnetically attracted to each other, and the fan head 100” may be fixedly connected to the swing mechanism 300”.

[0120] Specifically, when using the portable outdoor fan 10", the oscillation mechanism 300" can be placed on the base 400".

A locking groove 2321” is provided on the circumferential side of the outer casing 230”, providing a convenient method for subsequent fixing. A cylindrical positioning groove 101” is provided on the fan head 100”, adapted to the structure of the outer casing 230”, perfectly fitting the outer casing 230” to form a closed connection. Furthermore, a locking block 102” is provided within the cylindrical positioning groove 101”, adapted to the locking groove 2321”, providing a stable locking mechanism during fixing.

[0144] In some embodiments, during the process of fixing the control component 200” to the fan head 100”, the user can insert the housing 230” into the cylindrical positioning groove 101” of the fan head 100”. The operation steps are as follows: First, align the housing 230” with the cylindrical positioning groove 101”, ensuring that the snap-fit ​​groove 2321” and the snap-fit ​​block 102” are in relative positions. Then, the user gently rotates the housing 230”, and the snap-fit ​​block 102” will penetrate into the snap-fit ​​groove 2321”, forming a tight connection. Finally, by rotating, the snap-fit ​​block 102” and the snap-fit ​​groove 2321” are fastened and fixed, achieving a stable installation of the control component 200”. This design ensures that the housing 230” will not loosen due to external force during use, while simplifying the disassembly and replacement process. The user only needs to rotate the housing 230” clockwise to complete the installation and rotate it counterclockwise to disassemble, bringing great convenience to the user.

[0145] In one embodiment, continue as follows Figure 14As shown, a USB interface 212" for connecting to the rechargeable battery 210" is provided on the side of the housing 230" facing the fan head 100". The USB interface 212" is used to charge the control component 200" when it is detached from the portable outdoor fan 10" for later use. Specifically, after the control component 200" is detached from the portable outdoor fan 10", the user can easily connect the USB interface 212" to a power device such as a USB power adapter or computer to charge the rechargeable battery 210". This design makes charging more flexible, no longer limited to a specific charger or charging method.

[0146] In one embodiment, continue as follows Figure 14 As shown, a mating toothed disc 252” for mating with the fan head 100” and a magnetic nut 253 for fixing the mating toothed disc 252” are provided on the side of the drive motor 250” facing the fan head 100”.

[0147] Specifically, the mating gear disk 252” is commonly referred to as an “impeller,” “gear disk,” or “joint disk.” Its main function is to transmit the rotational motion of the motor to the fan blade assembly 120”, thereby driving its rotation to generate wind power. As a connector between the motor rotor and the fan blades, the mating gear disk 252” ensures efficient power transmission between the two; and through gears or other mechanical structures, the mating gear disk 252” transmits the torque output by the motor to the fan blade assembly 120”, thus achieving the rotation of the fan blades.

[0148] In some embodiments, the mating gear 252” is typically made of metal (such as cast iron, aluminum alloy) or high-strength plastic to withstand certain mechanical loads and impacts. The design dimensions and shape of the mating gear 252” need to match the design of the drive motor 250” and the fan blade assembly 120” to ensure effective rotation.

[0149] In some embodiments, the magnetic nut 253” primarily enhances the fixing and adsorption force of the mating toothed disc 252”, while improving overall stability and safety. Specifically, during the operation of the drive motor 250”, fan vibration may cause the mating toothed disc 252” to loosen. The magnetic nut 253” provides additional friction to help keep the mating toothed disc 252” fixed. Furthermore, due to the characteristics of the magnetic nut 253”, installing and removing the mating toothed disc 252” is more convenient than with ordinary nuts, enabling quick maintenance.

[0150] The technical advantages of the above solution are as follows: Firstly, the rechargeable battery ensures that the fan can be independently powered, meeting the needs of outdoor use. The control panel provides users with an intuitive interface for adjusting fan functions, and the detachable design of the casing allows users to quickly replace newly added control components. This design not only improves the ease of use of the fan but also effectively extends its service life and simplifies the installation of control components and other components. Secondly, by differentiating itself from existing technologies, this solution, through a rational structural design of the portable outdoor fan, simplifies the installation of control components and other components. Users can directly replace the battery when it is low, saving outdoor charging time and solving the battery life problem. Furthermore, since the control panel in the fan is a consumable component, integrating the control panel into the control component allows users to quickly replace the faulty control component when the control panel malfunctions, reducing interruptions caused by component failure and improving the user experience.
