Detailed Implementation

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0033] This embodiment provides an exhaust device that can adjust its exhaust function according to humidity, such as... Figure 1 It includes an exhaust fan 1, a remote controller 2 and a power module 3. The remote controller 2 includes a remote control module 4, a wireless transmission module 5 and a power supply processing module 6. The exhaust fan 1 includes a fan 7, a main control module 8, a wireless receiving module 9 and a humidity detection module 10.

[0034] The power supply processing module 6 converts the power supply from the power module 3 and outputs the operating voltage to the remote control module 4; the wireless transmission module 5 is signal-connected to the remote control module 4 and is used to transmit the control signals from the remote control module 4; the fan 7, the wireless receiving module 9, and the humidity detection module 10 are all signal-connected to the main control module 8; the wireless receiving module 9 of the exhaust fan 1 receives the control signals from the wireless transmission module 5 and transmits the received signals to the main control module 8; the main control module 8 controls the fan 7 to turn on or off according to the received control signals; the main control module 8 can be selected as GH8RF005.

[0035] Specifically, such as Figure 1As shown, the exhaust fan 1 in this embodiment can operate according to changes in ambient humidity, exhibiting a high degree of intelligence. The humidity detection module 10 detects the ambient humidity and transmits the detection signal to the main control module 8. The main control module 8 can set a humidity threshold. When the ambient humidity detected by the humidity detection module 10 exceeds this threshold, the main control module 8 controls the fan 7 to start for exhaust. When the detected ambient humidity is below the set threshold, the main control module 8 does not turn on the fan 7. Therefore, this embodiment eliminates the need for user control of the exhaust fan 1, making it more convenient to use and avoiding unnecessary running time, thus saving energy and reducing energy consumption. It also ensures timely dehumidification when humidity is high, preventing the growth of mold and bacteria, helping to maintain fresh indoor air and provide a healthy living environment. The humidity detection module includes a humidity sensor U9, an LED 8, and an LED 9. The detection output terminal of the humidity sensor U9 is connected to the main control module. Both LEDs LED 8 and LED 9 are connected to the main control module. LEDs LED 8 and LED 9 are different colors, and their specific connection methods are as follows: Figure 7 As shown, humidity is detected by humidity sensor U9 and transmitted to the main control module via SDA and SCL data lines. LED8 and LED9 can be used to indicate the humidity detection status, such as whether detection is in progress or not. This can be set according to actual needs.

[0036] Furthermore, this embodiment also includes a remote control 2, which allows for free control of the operation of the exhaust fan 1, such as... Figure 3 As shown, the power supply module 6 of the remote controller 2 includes an input rectifier unit 13, an input filter unit 14, a voltage regulator U1, and an output filter unit 15. The input terminal of the input rectifier unit 13 is connected to the power module 3. The output terminal of the input rectifier unit 13 is filtered by the input filter unit 14 and then input to the voltage regulator U1. The output terminal of the voltage regulator U1 is filtered by the output filter unit 15 and then outputs the power supply voltage. Figure 2As shown, the remote control module 4 of the remote controller 2 includes a remote controller U3, a button unit 11, and an indicator light unit 12. The remote controller U3 can be a GH8RF020. The button unit 11 is connected to the I / O port of the remote controller U3, and the indicator light unit 12 is also connected to the I / O port of the remote controller U3. When the button unit 11 is closed, the indicator light unit 12 lights up, and the remote controller U3 transmits the signal from the button unit 11 via the wireless transmission module 5. The button unit 11 includes a power button S1, a sleep button S2, and a fan button 7. The indicator light unit 12 includes a power indicator LED1, a sleep indicator LED5, and a fan indicator LED 7. The power button S1, sleep button S2, and fan button 7 are respectively connected to the three I / O ports of the remote controller U3. The power indicator LED1, sleep indicator LED5, and fan indicator LED 7 are respectively connected to the power button S1, sleep button S2, and fan button 7, respectively. The specific connection method is as follows: Figure 2 As shown, when the power button S1 is closed, the power indicator LED1 is lit by the remote controller U3; when the sleep button S2 is closed, the sleep indicator LED5 is lit by the remote controller U3; when the fan 7 button is closed, the fan 7 indicator light is lit by the remote controller U3.

[0037] Specifically, in this embodiment, the remote control 2 uses a 433 RF connection, the chip model of the wireless transmitting module 5 is GH445, and the chip model of the wireless receiving module 9 is HG710. The circuit principles of the wireless transmitting module 5 and the wireless receiving module 9 are as follows: Figure 4 and Figure 6 As shown. When the power button S1 is closed, the remote controller U3 receives the signal of the power button S1 being closed, and controls the power indicator LED1 to light up. It also transmits the signal to the wireless receiver module 9 through the wireless transmitter module 5. The wireless receiver module 9 transmits the received signal to the main control module 8. The main control module 8 then operates according to the received signal, such as turning on the power, putting the fan 7 into sleep mode, or turning on the fan 7 to perform exhaust work when the fan 7 button is closed.

[0038] like Figure 5 and Figure 8 The diagram shown is a circuit diagram of the main control module 8 and the fan 7 in this embodiment. The fan 7 includes a motor, a switching transistor Q2, and a relay K1. The output terminal of the main control module 8 is connected to the control terminal of the switching transistor Q2. One switching terminal of the switching transistor Q2 is grounded, and the other switching terminal of the switching transistor Q2 is connected to one electromagnetic control terminal of the relay K1. The other electromagnetic control terminal of the relay K1 is connected to the power supply module 3. The switching terminal of the relay K1 is used to control the motor to turn on and off. The specific connection method is as follows: Figure 5 Specifically, when the main control module 8 receives the signal to start the fan 7, it provides a signal to the switch Q2, causing the switch Q2 to conduct, which in turn energizes the relay K1 and closes, causing the motor to start working, and then the fan to start working to exhaust air.

[0039] The specific working principle of this embodiment is as follows:

[0040] 1. A 20V constant voltage power supply powers remote control 2 and exhaust fan 1. The power processing module 6 of remote control 2 converts the power supply into 12V and 3.3V operating voltages to power other components of remote control 2. Similarly, the 20V voltage is supplied through... Figure 9 The power conversion unit shown converts the voltage to 5V to power the components of exhaust fan 1.

[0041] 2. This embodiment has two operating modes. The first is passive exhaust, where the exhaust fan 1 is controlled by the remote control 2. For example, pressing the fan 7 button on the remote control 2 starts the exhaust fan 1; disconnecting the fan 7 button stops the exhaust fan 1. Disconnecting the main power switch stops both the remote control 2 and the exhaust fan 1. The operation of the exhaust fan 1 can be adjusted according to actual needs. The button unit 11 of the remote control 2 can also be further equipped with more buttons, as needed. This embodiment does not impose any restrictions. The second mode is active exhaust, where the humidity detection module 10 is activated by the humidity detection button on the remote control 2. After the humidity detection module 10 starts working, it monitors the ambient temperature in real time and transmits the results to the main control module 8. For example, if the detected humidity is ≥70% RH, the exhaust function is automatically activated; conversely, if the humidity is less than 50% RH, the exhaust fan 1 is automatically stopped. Disconnecting the humidity detection button disables this automatic dehumidification function. Furthermore, the working status can also be indicated by the indicator light unit 12: when the automatic dehumidification function is started, the blue indicator light can be set to flash for 2 seconds and then stop for 2 seconds (detection status). When the humidity detection value is ≥70%Rh, the indicator light will be solid blue. When the detected humidity detection value is ≤50%Rh, the blue indicator light will return to the detection status and flash. The working mode of the indicator light unit 12 can be adjusted according to actual needs, and there are no restrictions here.

[0042] In this embodiment, the humidity detection module 10 monitors the ambient humidity in real time, and the main control module 8 can then control the exhaust fan 1 to turn on or off according to actual needs, avoiding unnecessary running time, thereby saving power and reducing energy consumption; ensuring timely dehumidification when humidity is high, preventing the growth of mold and bacteria, helping to maintain fresh indoor air and provide a healthy living environment; in addition, it can reduce unnecessary working time of the exhaust fan 1, reduce mechanical wear, thereby extending the service life of the equipment and reducing maintenance costs; furthermore, the remote control 2 provides additional convenience, allowing users to adjust the working mode of the exhaust fan 1 according to their personal needs, making the control more flexible and practical.
