Its main function is to regulate indoor air quality, temperature and humidity, and it is widely used in machine rooms and other mechanical processing places.

[0003] Existing ventilation fans have a complex structure and unreasonable design. To cool the computer room, they operate continuously day and night. However, when the ambient temperature is low, they can stop working. Therefore, current ventilation fans lack intelligent control and can only blow air in one direction, resulting in low automation. Even in low temperatures, they continue to operate, increasing energy consumption and noise. Furthermore, during assembly, the various components of the panel are typically fixed with screws, requiring workers to use numerous screws, increasing the number of steps and reducing assembly efficiency. Therefore, the inventor has improved the structure of the ventilation fan. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent control ventilation fan. This intelligent control ventilation fan has a simple structure and reasonable design. When the ambient temperature reaches a preset high temperature threshold, the fan blades automatically operate to cool down, realizing automatic control of the fan blades and achieving the purpose of automatic cooling. The entire cooling process is fully automated, requiring no manual intervention, and has a high degree of automation. It also saves energy and avoids noise at low temperatures. The airflow direction can be switched as needed, thus meeting the usage needs of more different rooms. It eliminates the trouble of using screws during assembly, reduces the number of steps, and has the advantages of higher assembly efficiency, thus solving the problems mentioned in the above-mentioned technical background.

The display screen and the power supply are both located on the main board body and are located below the front guide frame.

[0007] Preferably, a fixing groove is provided at one end of the main board near the sub-board, and the circuit board, display screen and power supply are all fixed in the fixing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides an intelligent control ventilation fan, which includes a front panel and a rear panel disposed on one side of the front panel. A fan assembly and a control component located below the fan assembly are disposed between the front and rear panels. The overall structure is simple and reasonably designed.

This achieves automatic control of the fan blades and achieves the purpose of automatic cooling. The entire cooling process is fully automated and does not require manual intervention. It has a high degree of automation and is suitable for widespread use.

[0015] 2. During the operation of the fan blades in this utility model, the temperature and humidity sensor continuously monitors the ambient temperature.

This saves energy in low temperature conditions, avoids the fan blades from running continuously and increasing energy consumption, and also avoids noise generation at low temperatures. It is highly practical.

[0016] 3. The motor in this utility model is a forward and reverse motor, which can drive the fan blades to rotate forward or backward. In actual use, the airflow direction can be switched as needed, thus meeting the usage needs of more different computer rooms.

Multiple locking blocks are fixed on the inner wall of the front guide frame. Multiple locking holes are provided at the end of the front barrel near the front guide frame. The multiple locking blocks are respectively locked into the multiple locking holes. Through the cooperation of the multiple locking blocks and the multiple locking holes, the front guide frame and the front barrel are completely fixed as one unit.

This achieves automatic control of the fan blades 33 and realizes the purpose of automatic cooling. The entire cooling process is fully automated and requires no manual intervention, exhibiting a high degree of automation. When the ambient temperature falls below a preset low-temperature threshold, the temperature and humidity sensor transmits an electrical signal to the main control MCU 411 again, causing the motor 32 to be powered off and the fan blades 33 to stop rotating. This saves energy in low-temperature conditions, avoids the fan blades 33 from running continuously and increasing energy consumption, and also avoids noise generation at low temperatures. In this example, the high-temperature threshold is 35°C and the low-temperature threshold is 25°C. Furthermore, the main control MCU 411 is in a silent state and is only awakened when the high-temperature threshold is reached, thus exhibiting low power consumption.
