[0017] To address the aforementioned technical issues, this application provides a fan and a method and device for switching its airflow mode. By controlling the wind deflector to adjust the airflow volume of the dual air outlets according to the target airflow mode, the fan can flexibly switch between various airflow modes, improving the accuracy, adaptability, and flexibility of airflow adjustment.

[0018] Please see Figure 1 , Figure 1 This is a schematic block diagram of the fan structure provided in the embodiments of this application, such as... Figure 1 As shown, the fan includes a first air outlet, a second air outlet, an air outlet adjustment component, and a controller.

[0019] Specifically, the air outlet regulating component includes a wind deflector; The controller is configured to: receive an air outlet mode switching instruction; obtain a target air outlet mode corresponding to the air outlet mode switching instruction; determine a drive instruction based on the target air outlet mode; the drive instruction is used to control the wind deflector to change the air volume of the first air outlet and the second air outlet, thereby forming different air outlet modes.

[0020] A fan is a device that blows air outwards. The fans provided in this embodiment include, but are not limited to, household fans and industrial fans in terms of usage scenarios, and include, but are not limited to, desktop fans and standing fans in terms of type. This embodiment only uses a household desktop fan as an illustrative example. The air blown out by the fan can be cold or hot.

[0021] Furthermore, the fan also includes a fan assembly and a heating assembly. The fan assembly generates and outputs airflow, while the heating assembly heats the airflow to produce warm air output. The heating assembly includes a heating element, which is located on one side of the fan assembly. In other words, the heating element is located in the path of the airflow. When the heating element is working, it generates heat, which can increase the temperature of the air, making the blown air warm or hot. In this case, the fan can also be called a heater.

[0022] In some embodiments, the fan further includes a user interaction component. In determining the drive command based on the target airflow mode, the controller is configured to: acquire the current airflow mode; determine whether the current airflow mode is the same as the target airflow mode; if they are the same, send a prompt message to the user interaction component; if they are different, determine the drive command based on a preset airflow mode mapping dataset and the target airflow mode, wherein the airflow mode mapping dataset includes a mapping relationship between the target airflow mode and the drive command.

[0023] Furthermore, the fan also includes a user interaction component, which can be set on the surface of the fan body or can be a user terminal device independent of the fan, used to receive user input commands for switching airflow modes and to provide feedback on the current operating status to the user.

[0024] After receiving the air outlet mode switching command, the controller obtains the current air outlet mode and determines whether the current air outlet mode is consistent with the target air outlet mode. If they are the same, the controller sends a prompt message to the user interaction component to inform the user that the current air outlet mode is already in the target air outlet mode, thus avoiding repeated switching actions. If they are different, the controller matches the corresponding drive command with the target air outlet mode according to the preset air outlet mode mapping dataset. The air outlet mode mapping dataset stores the correspondence between the target air outlet mode and the drive command in advance. The controller can quickly obtain the drive command by querying the correspondence and control the wind deflector to adjust its position or size to execute the air outlet mode switching action.

[0025] The air outlet mode mapping dataset stores the correspondence between different air outlet modes on the surface, but in essence, it is the control parameters matched with different air outlet modes. When the controller determines the drive command based on the dataset, it can accurately control the adjustment of the position or size of the wind deflector according to the parameters matched with the target air outlet mode, making the switching process more stable and the adjustment accuracy higher, and ensuring that the air outlet mode switching is accurate and reliable.

[0026] As can be seen, in this embodiment, by adding a user interaction component and having the controller compare and judge the current air outlet mode with the target air outlet mode, timely feedback can be given to the user when the modes are consistent, avoiding invalid switching actions and improving the rationality of the control logic and the intuitiveness of user operation; when the modes are different, the drive command can be quickly determined according to the preset mapping relationship, making the air outlet mode switching more accurate and the response faster, while reducing the computing load of the controller and improving the system's operational stability and control reliability.

[0027] In some embodiments, the windbreak includes a first windbreak and a second windbreak, wherein the first windbreak is used to adjust the airflow of the first air outlet; the second windbreak is used to adjust the airflow of the second air outlet; the first windbreak and the second windbreak are connected and move up and down synchronously along the axis of the fan under the drive of the controller.

[0028] See Figure 2 , Figure 2 A perspective view of the fan provided in the embodiments of this application, such as... Figure 2 As shown, the fan includes a first air outlet 21 and a second air outlet 22. The first air outlet 21 is used to achieve a wide-range, diffused warm air output, while the second air outlet 22 is used to achieve a directional, concentrated warm air output. A first wind deflector 211 and a second wind deflector 221 are adapted to the fan. The first wind deflector 211 is used to adjust the airflow from the first air outlet 21, and the second wind deflector 221 is used to adjust the airflow from the second air outlet 22. The first wind deflector 211 and the second wind deflector 221 adopt an integrated linkage structure, moving synchronously up and down linearly along the central axis of the fan under the drive of the controller. By changing the relative position of the wind deflector and the air outlet, precise switching between different airflow modes is achieved.

[0029] In some embodiments, the controller is configured to: adjust the opening ratio of the first wind deflector relative to the first air outlet and the second wind deflector relative to the second air outlet, wherein the opening ratio is 0 or 1; the opening ratio refers to the ratio of the actual effective air outlet area to the total effective air outlet area.

[0030] The opening / closing ratio refers to the ratio of the actual effective air outlet area to the total effective air outlet area. This ratio directly quantifies the air outlet's airflow status. A value of 0 indicates that the wind deflector completely covers the corresponding air outlet, and the actual effective air outlet area is 0, i.e., it is in a windless mode. A value of 1 indicates that the wind deflector is completely detached from the corresponding air outlet, and the actual effective air outlet area is exactly the same as the total effective air outlet area, i.e., it is in a full air outlet mode.

[0031] Combining the integrated windbreak structure and the synchronous vertical linear movement along the central axis of this application, the controller can achieve stable switching between two core air outlet modes by precisely driving the windbreak to a preset displacement position that matches the opening and closing ratio of 0 or 1: When the controller drives the integrated windbreak to move synchronously down to the preset low position, the opening and closing ratio of the first windbreak relative to the first air outlet is 0, the first air outlet has no airflow, the opening and closing ratio of the second windbreak relative to the second air outlet is 1, the second air outlet is fully ventilated, and the fan outputs directional, concentrated warm air only through the second air outlet; When the controller drives the integrated windbreak to move synchronously up to the preset high position, the opening and closing ratio of the first windbreak relative to the first air outlet is 1, the first air outlet is fully ventilated, the opening and closing ratio of the second windbreak relative to the second air outlet is 0, the second air outlet has no airflow, and the fan outputs wide-range, diffused warm air only through the first air outlet.

[0032] This embodiment limits the opening and closing ratio to a binary value of 0 or 1, and combines it with the controller's precise control of the wind deflector's displacement position. This makes the fan's air outlet mode switching logic simple and the action execution stable. It does not require a complex graded control structure, and can meet the switching requirements between directional centralized air outlet and large-area diffused air outlet in basic heating scenarios. Furthermore, it is highly compatible with the integrated wind deflector structure, effectively ensuring the reliability of the equipment operation and the convenience of operation.

[0033] Based on this, in some embodiments, the air outlet mode mapping dataset specifically includes the following correspondence: the target air outlet mode is the full air outlet mode of the first air outlet, and the driving command is to control the wind deflector to move upward to a preset high position, and adjust the opening ratio of the first wind deflector to 1 and the opening ratio of the second wind deflector to 0; the target air outlet mode is the full air outlet mode of the second air outlet, and the driving command is to control the wind deflector to move downward to a preset low position, and adjust the opening ratio of the first wind deflector to 0 and the opening ratio of the second wind deflector to 1.

[0034] In this embodiment, the air outlet mode mapping dataset includes two air outlet modes and their driving commands. The core action of the driving commands is to control the first and second wind deflectors of the integrated linkage to move linearly along the central axis of the fan. By changing the relative position of the wind deflector and the air outlet, the 0 / 1 switching of the opening and closing ratio is accurately achieved.

[0035] When the user inputs a control command to the controller for the full air outlet mode, the controller retrieves the corresponding drive command from the air outlet mode mapping data set: controls the wind deflector to move upward and drives the displacement actuator to move the integrated wind deflector to a preset high position. In this position, the first wind deflector is completely separated from the first air outlet, and its opening ratio relative to the first air outlet is 1. The first air outlet achieves a large-scale, diffused warm air output with the total effective air outlet area. At the same time, the second wind deflector completely covers the second air outlet, and its opening ratio relative to the second air outlet is 0. The second air outlet has no warm air output.

[0036] When the user inputs a control command to the controller for the second air outlet in full-air-flow mode, the controller retrieves the corresponding drive command from the air outlet mode mapping data set: controls the wind deflector to move downwards and drives the displacement actuator to move, causing the integrated wind deflector to move down to a preset low position. In this position, the second wind deflector is completely detached from the second air outlet, and its opening ratio relative to the second air outlet is 1. The second air outlet achieves directional and centralized warm air output with the total effective air outlet area. At the same time, the first wind deflector completely covers the first air outlet, and its opening ratio relative to the first air outlet is 0. The first air outlet has no warm air output.

[0037] Building upon the basic control architecture that only achieves two-way switching between full airflow and no airflow at the first and second air outlets, this application aims to further enrich the fan's airflow adjustment dimensions and adapt to diverse scenarios such as small-area precise heating and localized constant-temperature supplementary heating. This is achieved by expanding the controller's control logic and adapting the wind deflector structure, allowing the first and second wind deflectors to be adjusted to opening ratios greater than 0 and less than 1, thus realizing graded airflow from a single air outlet. Furthermore, by supplementing and improving the airflow mode mapping dataset, a precise mapping relationship between graded airflow modes and corresponding drive commands is established, as detailed below: In some embodiments, the controller is configured to: adjust a first opening ratio of the first windshield relative to the first air outlet, wherein the first opening ratio is greater than 0 and less than 1; adjust a second opening ratio of the second windshield relative to the second air outlet, wherein the second opening ratio is 0 or 1; the air outlet mode mapping dataset includes the following correspondence: the target air outlet mode is a first air outlet graded air outlet mode, and the driving command is to control the windshield to move upward to a preset high position, and adjust the opening ratio of the first windshield to a value greater than 0 and less than 1, and the opening ratio of the second windshield to 0.

[0038] In this embodiment, the wind deflector retains the core structure of the integrated linkage between the first and second wind deflectors, which can move synchronously up and down along the central axis of the fan under the drive of the controller. Based on the requirement of graded air outlet, the wind deflector is designed with an adaptive structure so that it can partially cover the corresponding air outlet, thereby allowing the opening and closing ratio to be precisely adjusted to any preset value between 0 and 1. At the same time, the air outlet mode mapping dataset pre-stored in the controller is expanded on the basis of the original binary air outlet mode correspondence, and a graded air outlet mode for the first air outlet is added. The controller can output the wind deflector movement command and the opening and closing ratio adjustment command simultaneously according to the target air outlet mode, so as to realize the coordinated control of displacement and opening and closing.

[0039] In one possible example, in terms of structural improvement, the first windbreak includes a windbreak top cover and an air outlet grille structure, which are integrally connected and move up and down synchronously with the second windbreak along the central axis of the fan. The air outlet grille structure consists of a fixed grille layer and a rotating grille layer. The fixed grille layer is rigidly connected to the windbreak top cover, and the rotating grille layer is nested inside the fixed grille layer. It can rotate circumferentially around the central axis of the fan under the drive of a micro stepper motor. By changing the overlap area of ​​the fixed grille and the rotating grille, the opening and closing ratio of the first windbreak relative to the first air outlet can be infinitely adjusted. For example, when the first wind deflector rises to a preset high position, the second wind deflector completely covers the second air outlet. At this time, the controller can drive the rotating grid layer to rotate to different angles: if the rotating grid layer rotates until the grid gaps are completely aligned with the fixed grid gaps, the opening ratio of the first wind deflector is 1, and the first air outlet achieves large-scale diffused full air outlet with the total effective air outlet area; if the rotating grid layer rotates until the grid strips and the fixed grid gaps are each half-covered, the opening ratio of the first wind deflector is 0.5, and the first air outlet achieves medium-volume diffused air outlet with 50% effective air outlet area; if the rotating grid layer rotates until the grid strips completely cover the fixed grid gaps, the opening ratio of the first wind deflector is 0, and the first air outlet has no warm air output; by controlling the rotation angle of the rotating grid layer, the opening ratio can be precisely adjusted between 0 and 1 to meet the graded air outlet requirements in different scenarios.

[0040] When the user inputs a control command for the graded air outlet mode of the first air outlet into the controller, the controller retrieves the corresponding drive command from the expanded air outlet mode mapping dataset. This command includes two core execution actions: First, it controls the integrated wind deflector to move upward, causing the first and second wind deflectors to move synchronously upward to the preset graded air outlet high position. At this position, the second wind deflector still completely covers the second air outlet, and its opening ratio relative to the second air outlet remains at 0, so that there is no air output from the second air outlet. Second, it precisely adjusts the first opening ratio of the first wind deflector to a preset value that is greater than 0 and less than 1, so that the first wind deflector only partially covers the first air outlet. The actual effective air outlet area of ​​the first air outlet is the product of the total effective air outlet area and the first opening ratio, realizing graded control of large-area diffused air outlet (e.g., adjusting the first opening ratio to 0.3 to achieve micro-airflow diffused air outlet from the first air outlet; adjusting it to 0.7 to achieve large-airflow diffused air outlet from the first air outlet).

[0041] In this mode, the first opening ratio can be flexibly set between 0 and 1 according to heating needs. The controller precisely matches the preset opening ratio value by adjusting the opening and closing range of the wind deflector structure, so that the air volume of the first air outlet can be adjusted in a stepwise manner between no air and full air, which is suitable for scenarios such as constant temperature in small spaces and close-range non-direct blowing heating.

[0042] Based on the above embodiment of graded airflow from the first air outlet, in order to further improve the control dimensions of graded airflow from a single air outlet and adapt to the refined heating needs of directional and concentrated areas, this application also extends the control logic of the second baffle section and adds a mode of simultaneous airflow from both air outlets, enriching the application scenarios of the fan's airflow. The specific implementation is as follows: In some embodiments, the controller is further configured to: adjust a second opening / closing ratio of the second wind deflector relative to the second air outlet, wherein the second opening / closing ratio is greater than 0 and less than 1; adjust a first opening / closing ratio of the first wind deflector relative to the first air outlet, wherein the first opening / closing ratio is 0 or 1; the air outlet mode mapping dataset includes the following correspondence: the target air outlet mode is a graded air outlet mode of the second air outlet; the driving command is to control the wind deflector to move downward to a preset low position, and adjust the opening / closing ratio of the first wind deflector to 0 and the opening / closing ratio of the second wind deflector to a value greater than 0 and less than 1.

[0043] In this embodiment, the windbreak section retains the core structure of the integrated linkage between the first and second windbreak sections, and the motion mode of synchronously moving up and down linearly along the central axis of the fan remains unchanged. Moreover, the adaptable structural design of the windbreak section, such as through circumferential flaps, flexible roll-up curtains, or radial sliding baffles, can achieve stepless adjustment of the coverage area of ​​the side air outlets when in a preset low position, thereby completing precise control of the opening and closing ratio between 0 and 1. The air outlet mode mapping dataset pre-stored in the controller is further supplemented on the basis of the newly added first air outlet graded air outlet mode, and the mapping relationship between the second air outlet graded air outlet mode and the corresponding drive command is added. The controller can synchronously output the windbreak section movement command and the second opening and closing ratio adjustment command according to the target air outlet mode, realizing the coordinated control of displacement and opening and closing. The control logic is consistent with and compatible with the first air outlet graded air outlet mode.

[0044] When the user inputs a control command for the graded air outlet mode of the second air outlet into the controller, the controller retrieves the corresponding drive command from the expanded air outlet mode mapping dataset. This command includes two core execution actions: First, it controls the integrated wind deflector to move downwards, causing the first and second wind deflectors to move synchronously downwards to the preset graded air outlet low position. At this position, the first wind deflector still completely covers the first air outlet, and its opening ratio relative to the first air outlet remains at 0, with no air output from the first air outlet. Second, it precisely adjusts the second opening ratio of the second wind deflector to a preset value greater than 0 and less than 1, so that the second wind deflector only partially covers the second air outlet. The actual effective air outlet area of ​​the second air outlet is the product of the total effective air outlet area and the second opening ratio, realizing graded control of directional centralized air outlet (e.g., adjusting the second opening ratio to 0.2 to achieve micro-volume directional heat replenishment at the second air outlet; adjusting it to 0.8 to achieve large-volume directional heating at the second air outlet).

[0045] In this mode, the second opening ratio can be flexibly set between 0 and 1 according to actual heating needs. The controller precisely matches the preset second opening ratio value by adjusting the opening and closing range of the wind deflector, enabling step-by-step adjustment of the airflow from the second air outlet between no airflow and full airflow. This mode is highly compatible with the directional and centralized warm air output function of the second air outlet, enabling precise airflow replenishment to specific areas. It avoids the problems of excessive direct blowing and localized overheating in the single full airflow mode, making it suitable for scenarios such as precise close-range heating for a single person and constant temperature supplementation for localized areas. This further enriches the dimensions of fan airflow adjustment and improves the comfort and flexibility of heating.

[0046] Based on the aforementioned control implementation method of independent and graded airflow from the first and second air outlets, in order to further enrich the fan's airflow modes and adapt to diverse scenario requirements such as heating multiple people in a medium-sized space, targeted local heating, and overall temperature rise, this application further expands the airflow mode mapping dataset, adding a target mode of simultaneous airflow from both air outlets and corresponding driving commands. This achieves the coordinated output of wide-range diffused airflow from the first air outlet and directional concentrated airflow from the second air outlet. The specific implementation method is as follows: In some embodiments, the controller is configured to: adjust a first opening ratio of the first wind deflector relative to the first air outlet, wherein the first opening ratio is greater than 0 and less than 1; and adjust a second opening ratio of the second wind deflector relative to the second air outlet, wherein the second opening ratio is greater than 0 and less than 1; the air outlet mode mapping dataset includes the following correspondence: the target air outlet mode is a mode in which the first air outlet and the second air outlet simultaneously outlet air, and the driving command is to control the wind deflector to move upward to a preset middle position and independently adjust the opening ratio of the first wind deflector and the second wind deflector to a value between greater than 0 and less than 1.

[0047] In this embodiment, the fan retains the core structure of the integrated linkage between the first and second windshield sections, which can move synchronously up and down along the central axis of the fan under the drive of the controller. The adaptable structural design of the windshield sections supports independent adjustment of the opening and closing ratios of the first and second windshield sections, and the controller can achieve precise control of the two opening and closing ratios without interference. At the same time, the air outlet mode mapping dataset pre-stored in the controller is further supplemented on the basis of the original binary air outlet and single-port graded air outlet mode correspondence. A unique mapping relationship between the simultaneous air outlet mode of the first and second air outlets and the corresponding drive command is added. This drive command takes into account both the displacement positioning of the windshield section and the independent adjustment of the dual opening and closing ratios, realizing the coordinated control of the two. Moreover, the control logic is highly compatible with the single-port graded air outlet mode, without the need to modify the original drive mechanism and structural design.

[0048] When the user inputs a control command to the controller to simultaneously output air from the first and second air outlets, the controller retrieves the corresponding drive command from the expanded air outlet mode mapping dataset. This command contains two core execution actions, which are executed sequentially in the order of "first displacement positioning, then opening and closing adjustment": The integrated wind deflector is moved upward to a preset middle position. This middle position is different from the preset high position for the first air outlet's graded air output and the preset low position for the second air outlet's graded air output. It is a dedicated displacement node pre-stored by the controller to adapt to simultaneous air output from both air outlets. When the wind deflector is in this position, the first wind deflector does not completely cover the first air outlet, and the second wind deflector does not completely cover the second air outlet. Both air outlets have the basic conditions for air output, and this position is the initial state in which the two wind deflectors partially cover the two air outlets, reserving adjustment space for subsequent opening and closing ratio adjustment. With the wind deflector stably in the preset neutral position, the controller independently adjusts the first opening ratio of the first wind deflector and the second opening ratio of the second wind deflector, so that both are preset values ​​greater than 0 and less than 1. The first opening ratio determines the actual air volume of the first air outlet for wide-range diffusion, and the second opening ratio determines the actual air volume of the second air outlet for directional and concentrated air. The two can be set to the same or different values ​​according to heating needs, and the adjustment process does not interfere with each other.

[0049] In this mode, both the first and second opening ratios can be flexibly and independently set between 0 and 1. The controller precisely matches the preset opening ratio values ​​by adjusting the opening and closing amplitude of the dual air baffles, enabling the dual air outlets to simultaneously achieve graded air output, and the air volume can be freely matched to adapt to various actual heating scenarios: for example, setting the first opening ratio to 0.6 and the second opening ratio to 0.4 achieves the air output effect of "main diffusion synergy and auxiliary directional", meeting the needs of overall heating of large spaces while providing precise heat supplementation to local areas; or setting both the first and second opening ratios to 0.5 achieves balanced air output from the dual air outlets, adapting to the needs of multiple people in medium-sized spaces for decentralized heating.

[0050] The design of this dual-outlet simultaneous airflow mode, while fully retaining the original integrated linkage windbreak structure and without adding any additional drive mechanisms, upgrades from "single-outlet airflow" to "dual-outlet collaborative airflow" simply by expanding the airflow mode mapping dataset and adding a preset mid-position displacement node. This not only maintains the advantages of the original architecture in terms of simple control and structural stability, but also further improves the fan's airflow flexibility and scenario adaptability. At the same time, this mode coexists with the original binary airflow and single-outlet hierarchical airflow modes in the airflow mode mapping dataset, allowing users to switch freely according to their needs, greatly improving the product's user experience and practicality.

This satisfies the differentiated needs of wide-range diffused air outlet and directional concentrated air outlet, and improves heating comfort and scene adaptability through fine adjustment of air volume. The overall control logic is simple and reliable, and the structural layout is compact and reasonable.
