DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0026] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0027] See also Figures 1 to 6The present invention provides a fan 10, which includes a fan body 100, a power transmitter 200, a power adapter board 300, and a display operation circuit board 400. The power transmitter 200 is located outside the fan body 100, and the power transmitter 200 can be connected to an external power supply. The power transmitter 200 is provided with a wireless transmission circuit; the power adapter board 300 is located inside the fan body 100, and the power adapter board 300 is provided with a first wireless receiving circuit. The first wireless receiving circuit is used to receive electrical energy from the wireless transmitting circuit and is electrically connected to the fan body 100 to power the fan body 100; the display operation circuit board 400 is located inside the fan body 100, and the display operation circuit board 400 is provided with a second wireless receiving circuit. The second wireless receiving circuit is used to receive electrical energy from the wireless transmitting circuit to power the display operation circuit board 400.

[0028] In this way, compared with the traditional fan 10, the fan 10 of the present application integrates a wireless power supply function and does not need to adopt a data cable plug-in power supply method. Therefore, there will be no inconveniences such as poor contact, exposed wires, circuit aging, leakage, and data cable mixing. This solves the inconvenience of the smart fan 10 using a data cable plug-in power supply, and the user can use it whenever he puts it down without excessive operation, which greatly improves the convenience of use of the fan 10.

[0029] In addition, the second wireless receiving circuit is used to receive power from the wireless transmitting circuit of the power transmitter 200. In this way, the display operation circuit board 400 does not need a traditional wired power connection and realizes wireless power supply.

[0030] In some embodiments, the first wireless receiving circuit includes a first resonant circuit and a first rectifier circuit. The first resonant circuit typically consists of an inductor (coil) and a capacitor, forming an LC resonant circuit. The first resonant circuit is tuned to the same frequency as the wireless transmitting circuit to achieve optimal energy coupling. The first rectifier circuit typically includes components such as a diode (e.g., a bridge rectifier) ​​and a filter capacitor to provide a stable DC power supply.

[0031] In some embodiments, the second wireless receiving circuit includes a second resonant circuit and a second rectifier circuit, wherein the second resonant circuit is typically composed of an inductor (coil) and a capacitor, forming an LC resonant circuit. The second resonant circuit is tuned to the same frequency as the wireless transmitting circuit to achieve optimal energy coupling. The second rectifier circuit typically includes components such as a diode (e.g., a bridge rectifier) ​​and a filter capacitor to provide a stable DC power supply.

[0032] In some embodiments, the power transmitter 200 is typically connected to an external power source (such as a mains power source or a battery) to provide the required power.

[0033] In some embodiments, the display operation circuit board 400 is generally equipped with a display screen or other indicator device for displaying the working status, wind speed setting, timing information, etc. of the fan 10. The user can intuitively understand the current operating status of the fan 10 through this display information.

[0034] In some embodiments, the display operation circuit board 400 is generally provided with a touch screen or physical buttons, and the user can directly operate the fan 10 through these interfaces, such as adjusting the wind speed, setting a timer switch, selecting an operating mode, etc.

[0035] In some embodiments, the display operation circuit board 400 is wirelessly connected to the power adapter board 300 to control the operation of the fan body 100. The display operation circuit board 400 is connected to the power adapter board 300 via Bluetooth communication; or, the display operation circuit board 400 is connected to the power adapter board 300 via Wi-Fi communication. By controlling the button or touch screen of the display operation circuit board 400, the display operation circuit board 400 has an input signal (for example, a signal to make the motor 115 run, increase or decrease the speed, etc.), and the display operation circuit board 400 sends the input signal to the power adapter board 300. After receiving the signal, the power adapter board 300 feeds back the signal to the motor 115 of the fan body 100, so that the motor 115 is in the corresponding working condition. In this way, the wireless communication connection eliminates the physical wires between the display operation circuit board 400 and the power adapter board 300, reduces the wiring complexity, and reduces the production cost and maintenance difficulty.

[0036] In some embodiments, the fan body 100 includes a fan body 110, a rotating bracket 120, a support tube 130 and a base 140 connected in sequence. The fan body 110 includes a front mesh 111, a middle circle 112, a rear mesh 113 and a wind wheel 114. The front mesh 111, the middle circle and the rear mesh 113 are connected in sequence along the axial direction of the fan body 110. The front mesh 111, the middle circle and the rear mesh 113 together enclose a wind wheel accommodating space 116. The wind wheel 114 is installed in the wind wheel accommodating space 116. The fan body 110 has an air inlet and an air outlet. The air inlet is located at the rear mesh 113, and the air outlet is located at the front mesh 111.

[0037] The front mesh 111 is located in front of the fan 10 and serves to protect the user and prevent foreign matter from entering the fan 10. The holes or mesh design on the front mesh 111 allows air to be discharged smoothly from the interior of the fan 10, forming an air outlet. The middle ring 112 is located between the front mesh 111 and the rear mesh 113, providing structural support and enhancing the overall stability of the fan body 110. The rear mesh 113 is located at the rear of the fan 10 and also serves to protect the user and prevent foreign matter from entering the fan 10. The holes or mesh design on the rear mesh 113 allows air to be drawn into the fan 10 from the outside, forming an air inlet.

[0038] Thus, the impeller 114 is the core component of the fan 10. Driven by the motor 115, it draws air in through the air inlet and discharges it through the air outlet, generating the desired airflow. The fan body 110 generates airflow through the rotating impeller 114, drawing air in through the air inlet and discharging it through the air outlet, achieving air circulation. The design of the impeller 114 (such as the shape, number, and angle of the blades) directly affects the air volume and wind speed of the fan 10. The air volume can be adjusted by changing the speed of the motor 115.

[0039] In some embodiments, the fan body 110 further includes a motor 115, and the power adapter plate 300 is electrically connected to the motor 115 via a wire. The motor 115 is typically a high-efficiency brushless DC motor 115 (BLDC). This type of motor 115 has a high energy efficiency ratio, can provide stable power output, and reduce energy consumption.

[0040] In this way, the power adapter board 300 is directly electrically connected to the motor 115 via wires, ensuring that the motor 115 receives a stable power supply. This direct connection reduces the number of intermediate links and improves the efficiency and reliability of power transmission. The power adapter board 300 can rectify and stabilize the power received from the wireless transmission circuit, ensuring that the motor 115 receives the appropriate voltage and current, ensuring the normal operation of the motor 115.

[0041] In some embodiments, the power adapter board 300 may be integrated with a temperature sensor to monitor the temperature of the motor 115. If the temperature of the motor 115 is too high, the power adapter board 300 may automatically cut off the power supply to prevent the motor 115 from being damaged.

[0042] In some embodiments, the protection circuit built into the power adapter board 300 can quickly cut off the power supply when a short circuit or other electrical fault is detected, thereby protecting the motor 115 and the entire system from damage.

[0043] In some embodiments, the rear mesh 113 is recessed to form a motor accommodation space 117, and the motor 115 and the power adapter plate are located in the wind wheel accommodation space. In this way, the motor accommodation space 117 formed by the recessed rear mesh 113 can effectively integrate the motor 115 and the power adapter plate 300, making the entire fan 10 more compact and reducing the space occupied.

[0044] Furthermore, by concealing the motor 115 and power adapter board 300 within the rear grille 113, the overall appearance of the fan 10 becomes more concise and aesthetically pleasing, enhancing the product's visual appeal. Furthermore, the recessed space can be designed to facilitate heat dissipation. Appropriate ventilation holes or other heat dissipation measures ensure that the motor 115 and power adapter board 300 maintain good heat dissipation during operation, preventing overheating.

[0045] In some embodiments, the display and operation circuit board 400 is disposed on the front grille 111. The display and operation circuit board 400 may include mechanical buttons or a touch panel. By placing the display and operation circuit board 400 on the front grille 111, the user can intuitively view information displayed on the display screen of the display and operation circuit board 400, such as wind speed, timer settings, and ambient temperature, without having to navigate behind the fan 10 or to other locations. Furthermore, the user can adjust various functions of the fan 10 directly through the touchscreen or buttons on the front grille 111, improving user convenience.

[0046] In some embodiments, the base 140 includes a top plate 141, a bottom plate 142, and a counterweight 143. The top plate 141 and bottom plate 142 together enclose a space for accommodating the counterweight 143. The counterweight 143 is located in the space, and the support tube 130 passes through the top plate 141 and is connected to the bottom plate 142. This increases the overall weight of the base 140 and thus improves the stability of the fan 10. This prevents the fan 10 from tipping over or moving due to wind or other external forces during use.

[0047] In addition, the counterweight 143 is hidden in the counterweight 143 accommodating space formed by the top plate 141 and the bottom plate 142 and will not be exposed to the outside, thus keeping the appearance of the base 140 neat and beautiful.

[0048] In some embodiments, a counterweight 143 is disposed around the support tube 130. Thus, the counterweight 143 disposed around the support tube 130 evenly distributes the weight within the base 140, further improving the overall stability of the fan 10. This even distribution helps prevent the fan 10 from tipping over in any direction.

[0049] In addition, the counterweight 143 is disposed around the support tube 130 , which can more effectively concentrate the weight in the central area of ​​the base 140 , further lowering the center of gravity of the entire fan 10 and improving its anti-dumping capability.

[0050] In some embodiments, the fan body 100 includes a fan body 110, a rotating bracket 120, a support tube 130 and a base 140, the support tube 130 is connected between the rotating bracket 120 and the base 140, the rotating bracket 120 is located above the support tube 130, and the fan body 110 is rotatably connected to the rotating bracket 120 so that the fan body 110 can pitch and rotate relative to the rotating bracket 120.

[0051] In this way, the fan body 110 can be pitched and rotated around the rotating bracket 120, and the user can adjust the angle of the fan 10 as needed to make the air flow blow directly in the desired direction. This improves the flexibility of the fan 10 and meets the needs of different scenarios.

[0052] Furthermore, by adjusting the pitch, the fan 10 can cover a larger area, providing more even air circulation whether blowing upward or downward.

[0053] In some embodiments, the fan body 100 further includes a first drive mechanism comprising a first motor, a first gear, and a second gear. The first gear is fixedly mounted to the rotating bracket 120, the housing of the first motor is fixed to the fan body 110, and the second gear is meshed with the first gear. The drive shaft of the first motor is parallel to the horizontal direction. The drive shaft of the first motor is connected to the second gear to drive the second gear to rotate, thereby causing the fan body 110 to pitch relative to the rotating bracket 120.

[0054] In some embodiments, the rotating bracket 120 is rotatably connected to the support tube 130, allowing the rotating bracket 120 to rotate left and right relative to the support tube 130. This allows the rotating bracket 120 to rotate left and right around the support tube 130, allowing the user to adjust the horizontal direction of the fan 10 as needed, allowing the airflow to cover a larger area. This design allows the fan 10 to be adjusted not only vertically but also horizontally.

[0055] In some embodiments, the fan body 100 further includes a second drive device, which includes a second motor, a third gear, and a fourth gear. The third gear is fixedly mounted to the support tube 130, the housing of the second motor is fixed to the rotating bracket 120, and the fourth gear is meshed with the third gear. The drive shaft of the second motor is parallel to the vertical direction. The drive shaft of the second motor is connected to the fourth gear, driving the fourth gear to rotate, causing the rotating bracket 120 to rotate left and right relative to the support.
