Wherein, the push plates 423 of the pair of pop-up mechanisms 42 are supported under the pair of ear plates 412 in a one-to-one correspondence; the through hole of seting up on the U-shaped plate bottom plate corresponds with 11 positions of window on the 1 diapire of cigarette machine to make the camera can shoot the oil smoke of cigarette machine 1 below.
Preferably, in order to ensure that the transparent shielding plate 3 can be stably supported on the bottom plate of the U-shaped plate, the transparent shielding plate 3 of the present embodiment is configured to include a transparent shielding plate body 31 and a positioning frame 32 disposed around the transparent shielding plate body 31. Wherein, this positioning frame 32 includes: a horizontal plate 321 which is matched with the shape of the bottom plate of the U-shaped plate, and a vertical plate 322 which extends downwards from the bottom surface of the horizontal plate 321 and is arranged around the inner wall of the through hole on the bottom plate of the U-shaped plate 411.

The specific working flow of the automatic cleaning device of the embodiment is as follows:
first, when the transparent protection plate 3 needs to be cleaned, the controller starts the water pump on the water inlet pipe 53 to inject a predetermined amount of clean water into the cleaning tank 51, and meanwhile, the weight data sampled by the current gravity sensor 56 is obtained and recorded as G1, that is, G1 represents the weight of the cleaning tank 51 before water is introduced.
When the water injection is completed, the ultrasonic generator 52 is activated by the controller to sufficiently clean the transparent protection plate 3 in the cleaning tank 51.
After the cleaning is completed, the controller starts the water pump on the water outlet pipe 54 to discharge the sewage in the cleaning tank 51 outward, and obtains the real-time weight sampled by the gravity sensor 56, which is marked as G2. When G2< G1+ x, the controller determines that the wastewater in the cleaning tank 51 has been completely discharged, wherein x represents a preset weight deviation and the physical meaning represents the weight of the wastewater remaining on the inner wall of the cleaning tank 51 and the transparent protection plate 3.
When the controller judges that the sewage in the cleaning tank 51 is completely discharged, the controller turns off the water pump on the water outlet pipe 54 and simultaneously starts the dryer 55 to dry the transparent protection plate 3 in the cleaning tank 51.

firstly, acquiring the variance of the second derivative of the image data of each frame;
then, obtaining a difference value delta D between the variances;
and finally, determining the fuzzy degree of the transparent protection plate 3 according to the preset threshold range to which the difference value delta D belongs.
For example, when Δ D < a first threshold, the degree of blurring of the transparent shield 3 is determined to be severe; when the first threshold value is not more than delta D and less than the second threshold value, determining that the fuzzy degree of the transparent protection plate 3 is moderate; when the second threshold value is not more than delta D and less than the third threshold value, determining the fuzzy degree of the transparent protection plate 3 to be mild; when the delta D is larger than a third threshold value, the fuzzy degree of the transparent protective plate 3 is determined to be clear.
When the fuzzy degree of the transparent protection plate 3 is light, controlling the gear of the ultrasonic generator 52 to be 1 gear; when the fuzzy degree of the transparent protection plate 3 is moderate, controlling the gear of the ultrasonic generator 52 to be 2; when the degree of blurring of the transparent shielding plate 3 is severe, the gear of the ultrasonic generator 52 is controlled to be 3.
And S4, controlling the automatic transmission device to transmit the cleaned transparent protection plate 3 back to the initial position.
Specifically, the automatic transfer device is controlled to perform the step of step S2 in reverse to move the cleaned transparent shield plate 3 onto the window 11 which re-covers the bottom wall of the range hood 1.
Through the steps, automatic transmission and cleaning of the transparent protection plate 3 are achieved, time and labor are saved, meanwhile, corresponding cleaning gears can be automatically matched according to the fuzzy degree of the transparent protection plate 3, and the intelligent degree is further improved.
