[0033] An A / D converter, the full name is Analog-to-Digital converter, is an electronic device that is used to convert continuous analog signals into discrete digital signals.

[0034] As recorded in the background art, in the prior art, in order to improve the treatment effect during corona treatment of some products, a certain ozone concentration needs to be maintained in the corona treatment station. In the prior art, most ozone extraction fans in corona stations adopt star-delta starting control. When the ozone extraction fan is running normally, it operates at full load, thus completely extracting ozone, and it is relatively difficult to meet the technological requirement of maintaining a certain ozone concentration in the corona treatment station.

[0035] In view of this, the present application proposes a control device for a corona ozone extraction fan to adjust the extraction air volume, control the ozone concentration in the corona component, and improve the quality of special products.

[0036] Refer to Figure 2 , in some embodiments of the present utility model, a control device for a corona ozone extraction fan includes: an air extraction component 100, a control module 200, a concentration detection module 300, and a concentration setting module 400.

[0037] The concentration detection module 300 is installed on the corona component 500. The output end of the concentration detection module 300 is electrically connected to the input end of the control module 200. The concentration detection module 300 can detect the current ozone concentration in the corona component 500, obtain the ozone concentration value, and output the ozone concentration value to the control module 200.

[0038] The output end of the concentration setting module 400 is electrically connected to the input end of the control module 200. The concentration setting module 400 can respond to the trigger of the user, obtain the concentration setting value, and output the concentration setting value to the control module 200.

[0039] The control module 200 receives the ozone concentration value and the concentration setting value, compares the ozone concentration value and the concentration setting value, and outputs an adjustment signal to the air extraction component 100.

[0042] Exemplarily, the concentration setting module 400 responds to a user trigger to determine the set concentration value and outputs it to the control module 200. The concentration detection module 300 detects the ozone concentration in the corona component 500 to obtain the ozone concentration value and outputs it to the control module 200. The control module 200 compares the ozone concentration value with the set concentration value. When the ozone concentration value is greater than the set concentration value, the control module 200 outputs an adjustment signal for increasing the air extraction volume. The air extraction component 100 receives the adjustment signal for increasing the air extraction volume, increases the operating frequency, increases the air extraction volume, and reduces the ozone concentration in the corona component 500 so that the ozone concentration in the corona component 500 reaches the set concentration value.

[0043] Exemplarily, the concentration setting module 400 responds to a user trigger to determine the set concentration value and outputs it to the control module 200. The concentration detection module 300 detects the ozone concentration in the corona component 500 to obtain the ozone concentration value and outputs it to the control module 200. The control module 200 compares the ozone concentration value with the set concentration value. When the ozone concentration value is less than the set concentration value, the control module 200 outputs an adjustment signal for reducing the air extraction volume. The air extraction component 100 receives the adjustment signal for reducing the air extraction volume, reduces the operating frequency, reduces the air extraction volume, until the ozone concentration in the corona component 500 reaches the set concentration value.

[0044] Through the detection of the concentration detection module 300, the current ozone concentration value is determined. Through the concentration setting module 400 responding to a user trigger, the required set concentration value is determined. The control module 200 compares the set concentration value with the ozone concentration value and outputs an adjustment signal. The air extraction component 100 adjusts the air extraction volume of the ozone extracted from the corona component 500 according to the adjustment signal, thereby controlling the ozone concentration in the corona component 500, so that the ozone concentration of the set concentration value is maintained in the corona component 500, improving the corona treatment effect of special products and improving the quality of special products.
