[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures.

[0050] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] Existing air conditioning outlets typically use a fixed direction or a simple reciprocating airflow method, resulting in a single and constant airflow pattern. This is significantly different from the natural wind in which wind speed and direction fluctuate randomly. Long-term use can easily lead to discomfort for the human body, such as dryness, uneven temperature, localized overcooling, or "air conditioning sickness." Furthermore, it lacks the ability to dynamically respond to the human body's comfort needs.

[0052] This application uses a control module to execute a natural wind algorithm to generate dynamic control signals, which drive a motor to rotate a gear track disk. Utilizing the cooperation of the track groove and connecting rod, at least two groups of blades deflect asynchronously, dynamically switching between natural wind dispersion and wind concentration modes. This simulates irregular, fluctuating airflow close to a real environment, effectively solving the technical shortcomings of traditional mechanical wind modes, such as rigidity and poor comfort, and significantly improving the naturalness and human adaptability of the airflow. Figure 1-2 As shown, Figure 1 A schematic diagram of the frame of an electric air outlet provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of an electric air outlet provided in an embodiment of this application; the electric air outlet includes a drive motor, a gear track disk, at least two groups of adjustable blades, multiple connecting rods, and a control module.

[0053] In this embodiment, the drive motor is a miniature DC servo motor, which is installed inside the air outlet housing and serves as the power source for the entire system. In other embodiments, the drive motor may be selected from other power sources, and no limitation is made in this regard.

[0054] The gear track disk is connected to the output shaft of the drive motor through gear meshing, and its surface is provided with annularly distributed track grooves. The track grooves are composed of multiple independent curved channels, each channel corresponding to the motion path of a group of blades. The channel shape is optimized to realize asynchronous and nonlinear deflection of the blade group.

[0055] In this embodiment, two groups of adjustable blades are included, namely a first adjustable blade group and a second adjustable blade group; in other embodiments, 3, 4, 5 or more groups of adjustable blades may be included, and there is no limitation thereto.

[0056] Each adjustable blade group contains several blades arranged in parallel. The blades are rigidly connected by a linkage shaft to ensure that the blades in the group rotate synchronously.

[0057] Each group of blades is movably connected to the track groove on the gear track disk via a connecting rod. One end of the connecting rod is fixed to the linkage shaft, and the other end is equipped with a rolling bearing and embedded in the track groove. As the track disk rotates, it drives the blades to deflect.

[0058] The control module is integrated into the air outlet control circuit and has a pre-stored natural wind algorithm program. The control module is configured to execute the natural wind algorithm program to generate control signals. The control signals can be automatically generated based on user selection or environmental sensor input. The control signals are output to the drive motor to realize the output of natural wind.

[0059] The drive motor responds to the control signal output by the control module to drive the gear track disk to rotate. Through the cooperation of the track groove and the connecting rod, it drives at least two groups of blades to move at different deflection angles, thereby enabling the blade groups to dynamically switch between natural wind dispersion mode and natural wind gathering mode.

[0060] The following describes the working process of the electric air outlet in this embodiment:

[0061] When the user activates the natural wind mode, the control module calls the natural wind algorithm to generate a fluctuating control signal. The drive motor then precisely adjusts its speed and direction based on the signal, causing the gear track disk to rotate.

[0062] The trajectory groove drives each link to move along a predetermined curve, causing different blade groups to deflect at different angles and rhythms, realizing the dynamic dispersion (dispersion mode) and concentration (convergence mode) of airflow direction, thereby simulating an irregular air supply effect close to the real natural environment.

[0063] By dynamically switching between natural wind dispersion mode and wind gathering mode, irregular and fluctuating airflow is formed, effectively avoiding the dryness, uneven temperature and body stimulation caused by the direct airflow of traditional air conditioners, and providing a more comfortable experience that is closer to the natural outdoor wind.

[0064] In summary, the electric air outlet of this embodiment includes a drive motor; a gear track disk meshing with the output shaft of the drive motor, the surface of which is provided with annularly distributed track grooves; at least two sets of adjustable blade groups; multiple connecting rods, with the blades in each blade group movably connected to the track grooves via a corresponding connecting rod; and a control module pre-stored with a natural wind algorithm program. The control module is configured to execute the natural wind algorithm program to generate control signals and output them to the drive motor. The drive motor, in response to the control signals output by the control module, drives the gear track disk to rotate. Through the cooperation of the track grooves and connecting rods, it drives at least two sets of blade groups to move at different deflection angles, thereby dynamically switching the blade groups between a natural wind dispersion mode and a natural wind concentration mode. This improves the user experience by outputting natural wind.

[0065] The track grooves of the gear track disk include multiple independent curved channels distributed in a ring. Each curved channel is optimized according to the specific natural wind mode requirements to ensure that when the gear track disk rotates, each curved channel can drive the corresponding blade group to produce different deflection angles and rhythms.

[0066] Each curved channel corresponds to a connecting rod connecting to a blade group; and the shapes of multiple curved channels are configured such that, when the gear track disk rotates, it drives at least two blade groups to produce asynchronous deflection; to achieve the asynchronous deflection effect, the shapes, depths, and curvatures of the different curved channels vary. For example, some channels may be designed to be relatively gentle, causing the corresponding blade groups to deflect slowly within a certain range; while other channels may be designed with a rapidly changing shape, causing the corresponding blade groups to change direction quickly and significantly.

[0067] Each blade group is connected to a specific curved groove on the gear track disk via a connecting rod. One end of the connecting rod is fixed to the linkage shaft of the blade group, and the other end is equipped with a rolling bearing and embedded in the corresponding curved groove; the rolling bearing is used to reduce the frictional resistance when the gear track disk rotates; as the gear track disk rotates, the connecting rod moves along the curved groove, thereby driving the blade group to perform complex movements.

[0068] By designing a unique curved channel, different blade groups can deflect at different speeds and angles during the rotation of the gear track disk. This design breaks through the limitations of traditional synchronous sweeping modes, simulating a dynamic change effect that more closely resembles real natural wind and enhancing user comfort. Each blade group can move independently, thus adjusting the movement of each blade group according to a preset natural wind algorithm program to generate a more delicate and varied airflow pattern. This not only increases the realism of the natural wind mode but also better adapts to various environmental needs and personal preferences.

[0069] Each blade group consists of several parallel blades and a linkage shaft. The blades are rigidly connected by the linkage shaft to achieve synchronous deflection. The blades are rigidly connected together by a linkage shaft that runs through all the blades. The linkage shaft ensures that all blades in the blade group can deflect synchronously, thereby forming a consistent airflow direction. The linkage shaft is usually made of lightweight but high-strength materials, such as aluminum alloy, to reduce the overall weight while ensuring sufficient mechanical strength.

[0070] One end of the connecting rod is fixedly connected to the linkage shaft, while the other end is movably fitted into a track groove. Each group of blades is connected to a specific track groove on the gear track disk via a connecting rod. One end of the connecting rod is fixed to the linkage shaft, typically secured with bolts or other fasteners; the other end is equipped with a rolling bearing and movably fitted into a track groove on the surface of the gear track disk. This design allows the connecting rod to move along the track groove as the gear track disk rotates, thereby driving the blade group to deflect along a predetermined path.

[0071] The curve path of the trajectory slot is configured as follows:

[0072] like Figure 3 As shown, Figure 3This is a schematic diagram of the electric air outlet in natural wind dispersion mode. In natural wind dispersion mode, multiple groups of blades are driven to deflect in different directions. In natural wind dispersion mode, each curved channel guides the corresponding connecting rod to drive the blade group to deflect away from the central axis of the air outlet, so that the airflow is blown out in a divergent manner, covering a wider area.

[0073] like Figure 4 As shown, Figure 4 This is a schematic diagram of the electric air outlet in natural wind gathering mode. In natural wind gathering mode, multiple groups of blades are driven to converge and deflect towards the central axis. In natural wind gathering mode, the curved channel guides the connecting rod to drive the blade groups to converge towards the central axis, so that the airflow is concentrated and directed, enhancing the air delivery distance and intensity.

[0074] The control module outputs control signals in real time according to the natural wind algorithm program, which drives the motor to drive the gear track disk to rotate continuously. As the track disk rotates, the position of the connecting rod in the curved channel changes continuously, and the blade group switches periodically or randomly between "dispersing" and "converging", forming a fluctuating airflow similar to the alternating gusts and breezes in nature.

[0075] By precisely designing the trajectory groove path, the airflow at the outlet dynamically changes between "dispersion" and "convergence," effectively replicating the characteristics of alternating wind strength and random fluctuations in direction in nature. This significantly enhances the naturalness and comfort of the airflow, avoiding the discomfort caused by traditional constant direct airflow.

[0076] In diffused air mode, multiple sets of blades deflect in different directions, which can expand the airflow diffusion angle and achieve wide-area air delivery, suitable for quickly adjusting room temperature or shared spaces with multiple people; in concentrated air mode, the airflow is concentrated and the air delivery distance is longer, suitable for precise cooling or heating at fixed points, meeting the needs of diverse usage scenarios.

[0077] The natural wind algorithm program includes:

[0078] The sample-driven mode generates control signals based on pre-stored natural wind sample data of the target natural scene; the sample-driven mode includes:

[0079] Collect wind speed and wind volume sample data in the target natural scene; deploy high-precision anemometers and wind volume sensors in typical natural scenes (such as forests, seasides, and grasslands) to continuously collect dynamic data of real wind. For example, in a mountain forest environment, collect data sequences of wind speeds that fluctuate periodically between 0.5 and 3.5 m / s, accompanied by random gusts.

[0080] The sample data is filtered to extract feature waveforms; the original sample data is input into the digital signal processing unit, a low-pass filter is used to remove high-frequency noise interference, and the main frequency components (such as low-frequency fluctuations of 0.1 to 0.5 Hz) are analyzed by Fourier transform to extract the feature waveforms that represent the typical wind feel of the scene.

[0081] Control signals are generated through curve fitting algorithms; the extracted feature waveforms are transformed into executable control signal functions using cubic spline interpolation or least squares fitting techniques. For example, a control curve with a period of 8 seconds and a wind speed exhibiting sinusoidal superimposed pulse variations is fitted and used as the reference control command for the "Forest Breeze" mode. This command is then output to the drive motor to control the blade group to alternate between dispersing and concentrating wind according to this rhythm.

[0082] Dynamic generation mode, which generates control signals based on random function models or machine learning algorithms; dynamic generation mode includes:

[0083] The gust sub-mode generates instantaneous strong wind control sequences based on a random distribution model; instantaneous strong wind events are generated using a Poisson distribution model or a Gaussian noise model. For example, the system randomly triggers a "gust" every 30–90 seconds, lasting 2–5 seconds. During this period, the control signal causes the drive motor to accelerate briefly, driving the gear track disk to rotate rapidly, causing the blade group to quickly converge and then disperse, simulating the effect of a sudden strong wind followed by calm in nature.

[0084] The adaptive sub-mode uses machine learning algorithms to process user feedback data or environmental sensor data to dynamically optimize the wind speed fluctuation cycle parameter in the control signal. Integrating machine learning algorithms, the system receives the "comfort score" entered by the user in the APP via Wi-Fi or Bluetooth, and at the same time collects environmental data in conjunction with temperature and humidity sensors and infrared human body sensors.

[0085] The algorithm continuously adjusts key parameters in the control signal based on these inputs, including wind speed fluctuation period, wind dispersion / wind concentration switching frequency, and maximum deflection angle.

[0086] The control module is also configured to perform conventional swing functions, including:

[0087] The system can operate in either a left-sweeping mode, where all blades simultaneously deflect to the left, or a right-sweeping mode, where they simultaneously deflect to the right. In left-sweeping mode, the control module outputs a continuous positive pulse signal to the drive motor, causing the gear track disk to rotate clockwise within a preset angle range. This causes all blade groups to deflect synchronously to the left via the linkage and track groove. In right-sweeping mode, a reverse signal is output, causing the gear track disk to rotate counterclockwise, and all blades to deflect synchronously to the right. When set to "automatic sweeping," the control module controls the motor to periodically reverse direction, enabling the blade groups to oscillate back and forth between their left and right extreme angles.

[0088] This application also provides a natural wind control method, applied to the electrically operated air outlet as described in the above embodiment; Figure 5 As shown, Figure 5 A flowchart illustrating a natural wind control method according to an embodiment of this application includes the following steps:

[0092] S4: Through the cooperation of the track slot and the connecting rod, at least two groups of blades are driven to dynamically switch between natural wind dispersion mode and natural wind gathering mode.
