Description

Technical Field This utility model mainly relates to a ceiling fan structure. Background Technology Traditional ceiling fans or air conditioning fans have significant limitations in their control modes. For example, mechanical timers, fixed fan speeds, simple linear programs, or on / off temperature control are all open-loop controls that cannot dynamically adjust to ambient temperature. This often leads to problems such as excessive cooling during nighttime use due to temperature fluctuations, requiring manual intervention from the user. This not only affects sleep comfort but also wastes energy, failing to meet modern users' demands for intelligent, seamless, and adaptive comfort experiences. Utility Model Content To solve at least one of the above problems, this utility model proposes a new structural solution. The ceiling fan structure adopts the following technical solution: A ceiling fan structure includes a ceiling assembly, a motor, a light panel, and fan blades, with the fan blades disposed between the ceiling assembly and the light panel; The ceiling assembly includes a ceiling plate, a hanging bracket, a housing, a thermostat probe, and a controller.

[0008] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0009] The preferred embodiment provided by this utility model is as follows: Figures 1-5As shown, a ceiling fan structure includes a ceiling assembly 1, a motor 2, a light panel 3, and fan blades 4. The fan blades 4 are located between the ceiling assembly 1 and the light panel 3. The motor 2 is an external rotor motor 2, and the light panel adopts an existing structure, which will not be described in detail here.

[0010] The ceiling assembly 1 includes a ceiling plate 5, a hanging bracket 6, a housing 7, a thermostat probe 8, and a controller 9. The hanging bracket 6 is a plate with both ends folded up to form connecting feet 61. The hanging bracket 6 is fixed to the ceiling plate 5 through the connecting feet 61. The stator 21 of the motor 2 is connected to the hanging bracket 6. The fan blade 4 is composed of several blades 41 arranged in a circular pattern. The blades 41 are locked to the rotor of the motor 2.

[0011] The controller 9 is mounted on the bracket 6, and the temperature controller probe 8 is installed on the top plate 5. The controller 9 is connected to the temperature controller probe 8 and the motor 2. The controller 9 has a built-in temperature sensor, microcontroller, and drive circuit board.

[0012] The bottom surface of the top plate 5 is provided with a hook 51. A limit block 91 is fixedly connected to the side of the controller 9. A support rod 92 extends from the end of the limit block 91. The stator 21 is provided with a through hole 22. The support rod 92 passes through the through hole 22 and is wrapped around the hook 51 to limit the controller 9 to the hanger 6. The limit block 91 is set horizontally, and the limit block 91 and the through hole are on the same line to facilitate the insertion of the support rod 92.

[0013] The outer casing 7 has a cavity, in which the motor 2, the hanger 6, the temperature controller probe 8 and the controller 9 are housed. The inner side of the top of the outer casing 7 is provided with a protrusion 71, and the top plate 5 is provided with an L-shaped slot 51. The outer casing 7 and the top plate 5 are fixed together by the cooperation of the protrusion 71 and the slot 51.

[0014] Traditional ceiling fans and air conditioning fans typically employ relatively simple and fixed control modes, including: 1. Mechanical timer control: Users manually set the fan's running time, which stops when the time is up. 2. Fixed speed / level control: Offers several fixed speed levels (low, medium, high), which users manually select based on their comfort. However, when nighttime temperatures change, a fixed speed might be too cold in the latter half of the night, requiring the user to wake up and readjust. 3. Simple program control: such as "sleep mode," which usually involves the fan automatically reducing its speed or turning off after running for a period of time. However, this change is preset and linear, without considering actual ambient temperature variations. The core flaw of these traditional technologies is that they are all "open-loop" controls, unable to sense environmental changes and respond in real-time and flexibly. They require frequent user intervention and cannot provide a truly intelligent, comfortable, and seamless sleep experience.

[0015] This solution proposes a "temperature-following" mode, which is achieved through the coordinated operation of a sensor system, a control unit (MCU), and an actuator. The specific technical solution is as follows: Controller system composition: Temperature sensor: The core component, usually a high-precision NTC (negative temperature coefficient thermistor) or digital temperature sensor (such as DS18B20) is used to collect the temperature data of the environment where the fan is located in real time.

[0016] Microcontroller (MCU): The brain of the system, such as ARM Cortex-M series or ESP32 chips. It is responsible for receiving sensor data, running control algorithms, and outputting control signals.

[0017] Driver circuit board: Receives signals from the MCU (usually PWM pulse width modulation signals) and steplessly adjusts the speed (wind speed) of fan motor 2.

[0018] Alternatively, a human-computer interaction interface can be selected: a button, a remote control, or a mobile APP, for users to start the mode and set initial parameters (such as initial wind speed, desired temperature range, etc.).

[0019] Control methods and workflow (core algorithm): Step 1: Real-time monitoring. The temperature sensor continuously monitors the ambient temperature at a certain frequency (e.g., every 1-5 minutes) and transmits the data to the MCU.

[0020] Step Two: Data Processing and Judgment. The MCU compares the real-time temperature reading with the user-set comfort temperature range or the built-in algorithm model.

[0021] Step 3: Dynamic Adjustment (Core). Based on algorithm decisions, the MCU sends instructions to the driver circuit board to smoothly and steplessly adjust the fan speed. When the ambient temperature is high: the fan speed is automatically increased to enhance airflow, accelerate air circulation and evaporation of sweat, resulting in a stronger cooling sensation. When the ambient temperature gradually decreases: the fan speed is automatically and gradually reduced to decrease airflow, avoid overcooling, and maintain comfort. When the ambient temperature drops to a low threshold (e.g., below 26°C): the fan may automatically switch to an extremely gentle "light breeze" mode or enter standby mode, maintaining only a slight airflow.

[0022] Step 4: Cyclic Execution. Throughout the sleep period, the system continuously repeats the closed-loop process of "monitoring-judging-adjusting," thereby achieving the intelligent effect of dynamically adjusting the wind speed according to temperature changes.

[0023] Controller 9 and Temperature Sensor Installation: Controller 9 is installed inside the ceiling fan housing 7 and includes a temperature sensor. Temperature Sensor Installation: The temperature sensor probe passes through the hole in the top plate 5, with the probe exposed to the outside, allowing for real-time and accurate sensing of the ambient temperature. This solution's "temperature-following" control mode achieves "wind speed changes with temperature" through real-time temperature feedback → MCU dynamic speed adjustment → stepless closed-loop control, completely solving the pain points of traditional ceiling fans such as excessive cooling, temperature fluctuations, and manual adjustment, while combining comfort, energy efficiency, and intelligent features.
