Description

A Visualized Handheld Fan Temperature Control System Technical Field

[0001] This invention relates to the field of smart home appliance technology, specifically a temperature control system for a visual handheld fan. Background Technology

[0002] With the widespread use of portable electronic devices, handheld fans have become the preferred cooling tool for many users in summer or high-temperature environments due to their lightweight and portable features. Existing traditional handheld fans typically use physical buttons for simple speed switching and indicator lights to indicate the working status.

[0003] However, in practical use, existing handheld fan technology has the following main shortcomings:

[0004] The interaction methods are simplistic and the information presentation is not intuitive: Traditional fans mostly rely on physical buttons and simple LED lights, making it impossible for users to intuitively obtain the current wind speed level, ambient temperature, or internal device status (such as core temperature and precise battery level). In small devices, there is a lack of an interactive interface that can both make full use of limited space and transform abstract data into an intuitive visual language.

[0005] Lack of intelligent temperature control and emotional experience: Most products exist only as "cold tools" and cannot sense the temperature and humidity of the external environment or the status of their own internal components to automatically adjust the airflow (such as automatically strong wind when the temperature is high and automatically gentle wind when the temperature is low). They also lack mechanisms to communicate with users emotionally (such as providing feedback on the device status through facial expressions), resulting in a rather monotonous and boring user experience.

[0006] Low degree of personalization: The existing fan control logic and display interface are fixed at the factory, and users cannot customize the screen theme, dial layout or operating logic according to personal preferences or specific scenarios (such as sleep, outdoors), which limits the playability and applicability of the product.

[0007] To address this, we propose a visual handheld fan temperature control system. Summary of the Invention

[0008] 1. The problem to be solved

[0009] In view of the problems existing in the prior art, the purpose of this invention is to provide a temperature control system for a visual handheld fan to solve the problems mentioned in the background art.

[0010] 2. Technical Solution

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] A temperature control system for a visual handheld fan includes a main control unit, which is electrically connected to a drive unit, a sensing unit, an interactive display unit, and a wireless communication module. The interactive display unit is a touch screen embedded in the surface of the fan body. The sensing unit collects external environmental data and internal device status data and transmits them to the main control unit. The main control unit outputs control signals to the drive unit based on an intelligent temperature control algorithm and outputs display signals to the touch screen based on the system operating status. The touch screen presents a multimodal visual feedback interface including wind speed level, temperature data, and device status.

[0013] As a further aspect of the present invention: the display interface of the touch screen includes a dynamic particle wind effect area and a gradient color bar. The dynamic particle wind effect area renders the speed and density of particle flow according to the current actual wind speed value, and the gradient color bar is located at the edge of the screen and presents a corresponding color range according to the current temperature value.

[0014] As a further aspect of the present invention: the main control unit internally stores an expression interaction engine, which establishes a mapping relationship between device status data and expression animation frames. When the main control unit receives a power-on signal, a mode switching signal, or a specific temperature threshold signal, it calls the corresponding expression animation data and drives the touch screen to play it. The expression animation data includes at least: a power-on smiling face animation, a high-temperature sweating animation, and a Bluetooth connection animation.

[0015] As a further aspect of the present invention: the sensing unit includes an ambient temperature and humidity sensor and a core temperature sensor; the drive unit is connected to a brushless DC motor; the main control unit calculates the target duty cycle based on the data input from the ambient temperature and humidity sensor and outputs a PWM signal to the drive unit to adjust the speed of the brushless DC motor, increasing the speed under high temperature conditions and decreasing the speed under low temperature conditions.

[0016] As a further aspect of the present invention: the main control unit includes an overheat protection logic circuit. When the temperature value collected by the core temperature sensor exceeds a preset safety threshold, the main control unit sends a deceleration or shutdown command to the drive unit and simultaneously sends a warning emoticon display command to the touch screen.

[0017] As a further aspect of the present invention: the wireless communication module establishes a two-way data communication channel with the mobile terminal APP, the main control unit receives a configuration data packet from the mobile terminal APP, and updates the display parameters of the touch screen according to the configuration data packet, the configuration data packet including screen theme data, dial layout data and emoticon series data.

[0018] As a further aspect of the present invention: the main control unit executes scene triggering logic based on the mobile terminal APP. When the monitored ambient temperature value or the continuous running time of the device matches the triggering conditions set by the APP, the main control unit switches the system to sleep mode and renders the corresponding custom icon on the touch screen. In the sleep mode, the main control unit limits the maximum speed of the motor and reduces the backlight brightness of the touch screen.

[0019] As a further aspect of the present invention, it also includes a power management module connected to the main control unit. The power management module monitors battery voltage data. When the battery voltage data is lower than the low power threshold, the main control unit drives the touch screen to display a drowsy expression and perform a screen flashing action.

[0020] As a further aspect of the present invention: the wireless communication module packages and sends the environmental data and power information collected by the sensing unit to a mobile terminal APP, and the mobile terminal APP generates an environmental data curve and comfort suggestions.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention achieves intuitive visualization and interactive innovation of device status. By integrating a touch screen onto the fan body, dynamic particle effects are used to display wind speed, and gradient color bars are used to display temperature ranges, transforming the abstract wind speed settings and invisible ambient temperature of traditional fans into an intuitive and vivid visual language. This design not only solves the problem of unintuitive information presentation in small devices but also enhances the convenience and technological feel of user operation.

[0023] 2. This invention is based on a highly personalized customization architecture of mobile internet. Unlike the fixed functions of traditional fans, this system allows users to customize screen themes, dial layouts, and scene triggering logic (such as sleep mode) through an app, realizing the transformation from a standardized product to a "personalized" device, greatly expanding the application scenarios and functional extensibility of the fan.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figures 1 to 3. The present invention provides a temperature control system for a visual handheld fan.

[0030] The core hardware architecture of this embodiment is shown in Figure 1. The system includes a main control unit (MCU), and a drive unit, a sensing unit, an interactive display unit, a wireless communication module, and a power management module, all electrically connected to the main control unit. At the physical structure level, as shown in Figure 2, the interactive display unit is configured as a touchscreen 2 embedded in the surface of the fan body 1. The sensing unit integrates an ambient temperature and humidity sensor and a core temperature sensor, used to collect external environmental data and internal heat dissipation data, respectively. The drive unit connects to a brushless DC motor, responsible for outputting power to the fan.

[0031] It should be noted that in this embodiment, the position of the touch screen 2 is not limited to the central axis area of ​​the fan head; it can also be located on the handle of the fan body 1. The initial design intention is to solve the technical problem of the lack of information feedback in traditional handheld fans through a visual interface. By transmitting abstract device status data (such as wind speed, temperature, and battery level) to the touch screen 2 for rendering, this system can intuitively present the device's operational details, improving the efficiency and intuitiveness of human-computer interaction.

[0032] The circuit connections, sensor data acquisition, and signal transmission processing involved in this embodiment are conventional technical applications in the field of electronic engineering. This specification does not elaborate on specific circuit board wiring or general underlying driver protocols. The relevant hardware selection should comply with national electrical safety standards.

[0033] To provide intuitive wind and temperature feedback, the touchscreen 2's display interface is divided into different functional areas. As shown in Figure 2, a gradient color bar 3 is set at the edge of the screen. The main control unit receives the ambient temperature value uploaded by the sensing unit and, based on a preset temperature zone algorithm, controls the gradient color bar 3 to display the corresponding color spectrum: cool colors (such as blue) are displayed in the low-temperature zone, and warm colors (such as red) are displayed in the high-temperature zone. At the same time, the central area of ​​the screen is configured as a dynamic particle wind effect display area. The main control unit calculates the velocity vector and density distribution of particle flow based on the current output power of the drive unit, so that the visual wind speed displayed on the screen is synchronized with the actual physical wind speed.

[0034] It's worth noting that this multimodal feedback mechanism not only enhances the product's technological feel but, more importantly, establishes a visual connection between the user and their environment. Through the hue changes of the gradient color bar 3, users can anticipate the comfort level of the environment without physically probing, while the dynamic particle effect compensates for the stiffness and lack of dynamism in traditional digital display, providing a more natural way of conveying information.

[0035] This system employs closed-loop control logic to achieve intelligent temperature control. As shown in Figure 3, the main control unit calculates the suitable wind speed for the current environment based on data collected by the ambient temperature and humidity sensors using an internal algorithm, and outputs a PWM signal with the corresponding duty cycle to the drive unit. The drive unit then adjusts the speed of the brushless DC motor accordingly, achieving automatic speed increase in high-temperature environments and automatic speed decrease in low-temperature environments.

[0036] Meanwhile, the system has built an overheat protection mechanism based on the internal temperature sensor of the mechanism. When the internal temperature of the mechanism exceeds the preset safety threshold, the main control unit will determine that the device is in an abnormally high load state, and then send a deceleration or shutdown command to the drive unit, and simultaneously drive the touch screen 2 to display a human-like warning expression (such as "sweating" or "blushing") until the temperature drops back to the safe range.

[0037] It should be noted that this protection logic effectively solves the problem of motor overheating and damage caused by prolonged high-load operation of traditional fans, extending the service life of the fan body 1 and its internal components. At the same time, through visual warning emoticons, users can promptly understand the cause of equipment malfunction, avoiding safety hazards caused by blind operation.

[0038] The system incorporates an interactive expression engine that establishes a mapping between device status and animation frame sequences. In addition to the aforementioned high-temperature warning, the main control unit also monitors battery voltage data from the power management module. When the voltage falls below the low-battery threshold, the main control unit drives the touchscreen 2 to display a "drowsy" or "yawning" animation and controls the screen backlight to perform a breathing flashing motion. Furthermore, upon power-on or successful Bluetooth connection, the screen will play a "smiley face" or connection animation.

[0039] It's worth noting that this anthropomorphic interactive design transforms cold device status data into emotionally resonant expressions, reducing the user's cognitive load. Compared to traditional, simple LED indicator flashing, animated expressions convey urgent information such as "low battery" or "device overheating" more accurately and in a more friendly way, enhancing the user experience.

[0040] This system establishes a two-way data channel with a mobile terminal APP via a wireless communication module. On one hand, the system packages and uploads historical temperature and humidity data and power information collected by the sensor unit, and the APP generates environmental data curves and comfort suggestions. On the other hand, the system supports open custom configuration. Users send configuration data packages through the APP, and the main control unit receives and updates the theme, dial layout, and emoji resources of the touchscreen 2.

[0041] Furthermore, the system supports scenario-based automation logic. Users can set trigger conditions in the app (such as "ambient temperature below 26 degrees Celsius" or "running time exceeding 30 minutes"). When the conditions are met, the main control unit automatically switches to sleep mode. In this mode, the main control unit limits the maximum speed of the motor to reduce noise and significantly reduces the brightness of the touchscreen 2, while rendering a specific sleep icon.

[0042] It's worth noting that the open, customizable architecture significantly expands the applicable scenarios for the fan unit 1, transforming it from a single-function cooling tool into a personalized smart device suitable for various occasions such as sleep, office, and outdoor use. Through the synergy of hardware and software, it meets the diverse needs of different user groups.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
