In particular, the circuit configuration of the indoor air quality improvement system 100 of the present invention is not limited thereto.

Specifically, when the indoor gas concentration of 210 does not meet the air quality standard, it often reaches the level of harm to human safety, and human beings may lose their ability to judge and move in a very short period of time. The indoor air quality improvement system 100 of the present new type can switch to the automatic mode when the indoor 210 does not meet the air quality standard, that is, automatically start the windmill motor 120 and automatically fully open the air pressure gate 110 . In this way, the air 170 in the indoor 210 can be discharged to the outdoor 220 as soon as possible, and the fresh air 170 of the outdoor 220 can quickly enter the indoor 210, thereby increasing the circulation of the air 170 in the indoor 210, accelerating the improvement of the air quality state of the indoor 210, and instantly Eliminate unfavorable conditions for the human body.

Further, when the sensor 130 detects that the gas concentration in the room 210 does not meet the air quality standard state, it is determined as an air quality warning state, and the air quality warning state may be a harmful state, a dangerous state and a hazardous state.

In other embodiments, the operating intensity of the windmill motor 120 can be adjusted by other means, but the present invention is not limited to this.

Therefore, the indoor air quality improvement system 100 of the present invention can automatically adjust the operating intensity of the windmill motor 120 according to different levels of air quality warning states. Intermittently maintain a high power operating intensity, and achieve the effect of energy saving.

Specifically, the harmful state is that the oxygen concentration is less than or equal to 17% and greater than 14%, the carbon monoxide concentration is greater than or equal to 70 PPM and less than 150 PPM, or the carbon dioxide concentration is greater than or equal to 1000 PPM and less than 3000 PPM. Hazardous states are oxygen concentrations less than or equal to 14% and greater than 9%, carbon monoxide concentrations greater than or equal to 150 PPM and less than 400 PPM, or carbon dioxide concentrations greater than or equal to 3000 PPM and less than 5000 PPM. Hazardous states are oxygen concentrations less than or equal to 9%, carbon monoxide concentrations greater than or equal to 400 PPM, or carbon dioxide concentrations greater than or equal to 5000 PPM. As long as the concentration of any gas reaches the preset value of the state, the controller 140 determines that the current indoor 210 is the state.

When the sensor 130 detects that the gas concentration in the room 210 meets the air quality standard state; that is, the oxygen concentration is greater than 17%, the carbon monoxide concentration is less than 70 PPM, and the carbon dioxide concentration is less than 1000 PPM, the controller 140 controls the windmill motor 120 Stop the operation, and control the air pressure gate 110 to be completely closed. When the indoor 210 meets the air quality standard state, it means that the air quality is good and there is no need for improvement. Therefore, if the windmill motor 120 is continuously operated, it may lead to waste of energy. Therefore, the air 170 in the indoor 210 can be stabilized by the above automatic action. circulation, and achieve the effect of energy saving.

On the other hand, the indoor air quality improvement system 100 can be switched to the manual mode when the air quality standard state is met. In the manual mode, the opening rate of the air pressure gate 110 can be manually selected through the controller 140 to meet various usage scenarios.

Specifically, by adjusting the opening rate of the air pressure gate 110 , the pressure in the indoor 210 can be controlled, and the indoor 210 can be stably maintained in a negative pressure state, so as to increase the ventilation rate of the indoor 210 and maintain the indoor 210 clean air. In this way, the risk of mutual infection between different spaces can be avoided, which can meet the needs of infectious disease prevention.

When the indoor air quality improvement system 100 meets the air quality standard, the controller 140 can control the opening rate of the air pressure gate 110 to be the first opening rate, the second opening rate or the third opening rate. The first opening rate is greater than the second opening rate, and the second opening rate is greater than the third opening rate. Specifically, the first opening rate may be 50% to 100%, the second opening rate may be 25% to 50%, and the third opening rate may be 0% to 25%. Thereby, the pressure in the chamber 210 can be adjusted accordingly.

Specifically, when the opening rate is the first opening rate, the pressure in the chamber 210 may be 0.95 atm to 1 atm, and the chamber 210 may be in a low negative pressure state. When the opening rate is the second opening rate, the pressure of the chamber 210 may be 0.85 atm to 0.95 atm, and the chamber 210 may be in a negative pressure state. When the opening rate is the third opening rate, the pressure of the chamber 210 may be below 0.85 atm, and the chamber 210 may be in a state of strong negative pressure.

In addition, in the manual mode, the operating intensity of the windmill motor 120 can also be manually adjusted, and can be adjusted to the above-mentioned first wind speed, second wind speed or third wind speed. In this way, by adjusting the opening rate of the air pressure gate 110 and the operating intensity of the windmill motor 120, various and changeable air quality improvement effects can be produced, and can more adaptively meet various needs of users.

As shown in FIG. 1 , the indoor air quality improvement system 100 may further include a first filter device 151 connected to the air pressure gate 110 , and the first filter device 151 is used to filter the air 170 entering the room 210 from the outdoor 220 .

The indoor air quality improvement system 100 may further include a second filter device 152 connected to the windmill motor 120 , and the second filter device 152 is used for filtering the air 170 discharged from the indoor 210 to the outdoor 220 . Thereby, the harmful gas in the room 210 can be prevented from being directly discharged.

In addition, the indoor air quality improvement system 100 may further include a display screen 160 whose signal is connected to the sensor 130 , and the display screen 160 displays the gas concentration and pressure in the room 210 . Thereby, the user can monitor the gas concentration and pressure in the room 210 at any time. The display screen 160 can be connected to the controller 140 by a signal, and can further include an operation interface (not shown in the figure), through which the user can select the opening rate of the air pressure gate 110 and the opening rate of the windmill motor 120 in the manual mode through the operation interface. Operation strength, in order to improve the convenience of use.

To sum up, when the indoor gas concentration does not meet the air quality standard state, the new indoor air quality improvement system can automatically start the windmill motor, and automatically fully open the air pressure gate, thereby improving the indoor air quality immediately. air quality and avoid exposing users to dangerous conditions.
