Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically to a device that simulates a person manually fanning themselves. Background Technology

[0002] When the weather is hot and the temperature is high, people always long for a fan. By holding the handle and constantly fanning themselves with the large surface area at the top, they can create a cool breeze to relieve the feeling of heat and discomfort. Fans are essential items for creating a breeze and are a summer necessity. Chinese traditional fan culture has a profound cultural heritage and is an integral part of Chinese culture. In traditional Chinese society, fans were closely related to people's daily lives. The types of fans include feather fans, palm leaf fans, pheasant fans, round fans, folding fans, silk palace fans, gold-leaf fans, black paper fans, sandalwood fans, and so on.

[0003] Current household fans can only be used manually, which is not easy to use, takes up a hand space, and the fanning process can also cause some heat due to the movement. This is especially true for children, so the effect is not good and they are not easy to accept. Utility Model Content

[0004] To solve the above-mentioned technical problems, a device simulating manual fanning is provided. This technical solution solves the problems mentioned in the background art, such as existing household fans can only be used manually, which is not labor-saving, occupies a hand space, and the fanning process can cause a certain amount of heat due to the movement, which is especially undesirable for children.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device simulating a human hand fanning, comprising a base plate, a protective shell at the top of the base plate, and a swing mechanism inside the protective shell, the swing mechanism being electrically connected to a controller via a connecting wire;

[0007] The swing mechanism includes a mounting plate, which is fixedly mounted on the top of the base plate. A drive motor is provided on the rear side of the mounting plate. The output end of the drive motor passes through the front side of the mounting plate and is fixedly connected to the rotating plate.

[0011] Preferably, the controller has a relay inside and a Bluetooth module inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] First, the drive motor rotates the rotating plate, which in turn causes the connecting plate to move the movable plate in a regular reciprocating motion, achieving an automatic fan effect. This frees the user's hands, allowing them to enjoy the coolness while engaging in other activities, thus improving convenience and comfort. Second, the controller precisely controls the drive motor, allowing users to flexibly adjust the fan frequency and intensity according to their needs.

[0025] 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.

[0026] Reference Figures 1-4 As shown, a device simulating a human hand fan includes a base plate 1, a protective shell 2 is provided on the top of the base plate 1, and an oscillating mechanism 3 is provided inside the protective shell 2. The oscillating mechanism 3 is electrically connected to a controller 6 through a connecting line 5.

[0027] The swing mechanism 3 includes a mounting plate 301, which is fixedly mounted on the top of the base plate 1. A drive motor 302 is provided on the rear side of the mounting plate 301. The output end of the drive motor 302 passes through the front side of the mounting plate 301 and is fixedly connected to the rotating plate 303. The front side of the rotating plate 303 is rotatably mounted on one end of the connecting plate 304. The other end of the connecting plate 304 is rotatably mounted on the right top of the movable plate 305, which has a connecting groove 306. The movable plate 305 is rotatably mounted on the front side of the mounting plate 301. Both the top of the movable plate 305 and the connecting plate 304 are provided with connecting rings 307. Both sets of connecting rings 307 have rubber bands 308 inside. The top of the movable plate 305 is fixedly mounted with a fan 4 through two sets of rolling strips 309. The movable plate 305 is movably mounted in the movable groove 201 opened on the right top of the protective shell 2.

[0028] In this design, the drive motor 302 drives the rotating plate 303 to rotate, converting the rotational power into the pushing and pulling action of the connecting plate 304, which in turn drives the movable plate 305 to swing regularly. The elastic connection structure between the rubber band 308 and the connecting ring 307 reduces the structural wear of the fan 4 during high-speed swing by buffering mechanical vibration, thus extending the service life of the device. The detachable fixing method of the rolling strip 309 enables the quick replacement of the fan 4. The cooperation structure between the protective shell 2 and the movable groove 201 restricts the movement trajectory of the movable plate 305, ensuring that the fan 4 swings stably within a safe range. Furthermore, a "Danger" sign can be affixed around the corresponding movable groove 201.

[0029] Reference Figure 2 As shown, the drive motor 302 is electrically connected to the controller 6 via the connecting wire 5. A speed adjustment knob 601 is rotatably mounted on the front side of the controller 6, and a timing knob 602 is rotatably mounted on the top of the controller 6.

[0030] In this solution, the drive motor 302 is electrically connected to the controller 6. The controller 6 uses an STM32F103C8T6 microcontroller as its core, achieving precise control over fan speed and running time. The controller 6 is designed for 220V AC power supply with a rated power of 50W. It has a built-in microprocessor chip and adjusts the motor speed through PWM pulse width modulation technology. It also features a speed control knob 601, which changes the resistance value by rotating and sends a signal to the microprocessor, achieving stepless adjustment of fan intensity. The timer knob 602 uses a mechanical timer structure, which drives a contact switch through a spring-loaded gear set, enabling a timer shutdown function for up to 120 minutes. The controller 6 integrates an overload protection circuit, which automatically cuts off the power supply when the current exceeds 2A, ensuring safe operation in a home environment.

[0031] Reference Figure 4 As shown, the controller 6 has a relay installed inside, and the controller 6 also has a Bluetooth module installed inside.

[0032] In this solution, the device uses a controller 6 of model HC-05, which achieves precise timing control of motor start and stop through built-in relays, thereby simulating the intermittent oscillation effect of natural fan wind. Secondly, by setting up a low-power Bluetooth module, remote linkage with smart terminals is realized through wireless communication protocol. Users can customize the wind speed level and oscillation cycle. The controller 6 is based on the PWM pulse width modulation principle, which changes the motor speed by adjusting the duty cycle. At the same time, it integrates an overload protection circuit to ensure the stability of the device under long-term operation. Furthermore, a programmable logic chip is used to realize the automatic switching of three wind speed modes through preset algorithms.

[0033] The working principle of this utility model is as follows: First, when the drive motor 302 receives the PWM speed control signal from the controller 6, it drives the rotating plate 303 to rotate. The rotational motion is converted into a reciprocating push-pull action through the connecting plate 304, driving the movable plate 305 to swing around the mounting plate 301. The elastic band 308 is elastically deformed in the connecting ring 307 to absorb the impact force during the swing process and reduce the mechanical wear of the fan 4. The controller 6 changes the speed of the drive motor 302 by adjusting the PWM duty cycle, thereby controlling the swing frequency of the fan 4. Second, the timer knob 602 controls the relay to switch on and off through the mechanical gear set to achieve a timer operation of up to 120 minutes. Third, when the Bluetooth module receives external instructions, the controller 6 switches to three wind speed modes according to the preset program. The overload protection circuit cuts off the power when the current exceeds 2A. The fan 4 is fixed to the movable plate 305 by the belt 309 and generates airflow as it swings. The protective shell 2 limits the swing amplitude to ensure safety.
