Example Embodiment
[0036] Example 1
[0037] see Figure 1 to Figure 8 , the present invention is an automatic cleaning range hood, comprising a casing 1, a main engine arranged in the casing 1 and separated from the inner cavity of the casing 1, the main engine comprising an air suction cavity 2 with a mesh plate 21, and an exhaust air cavity is provided. The motor 31 is connected to the blast chamber 3 that drives the first impeller 32 , the exhaust chamber 4 that communicates with the blast chamber 3 and extends out of the casing 1 , the oil suction device 5 and the air supply device 6 . The air suction chamber 2 , the air blast chamber 3 and the air exhaust chamber 4 are sequentially communicated and arranged in the main body chamber, and the screen plate 21 is provided with an automatic cleaning device 7 .
[0038] Further, the annular groove 33 is provided at the connection between the blast chamber 3 and the suction chamber 2 at the front end of the first impeller 32 , and the opening of...
Example Embodiment
[0050] Embodiment 2
[0051] like Figure 9 As shown, the second embodiment is substantially the same as the automatic cleaning range hood of the first embodiment, the difference is that the automatic cleaning device of the second embodiment includes a rotating scraper a71, a fixed screen a21 and a reducer a72. The scraper a71 is in contact with the screen a21, the exhaust motor shaft is connected to the first impeller and then connected to the reducer a72, the output shaft of the reducer is connected to the rotating scraper a71, and the opposite end of the rotating scraper a71 is connected to a scraper gear ring a74 , meshing with the driving gear a73, the driving gear a73 drives the scraper a71 to rotate. In order to stabilize the rotation of the scraper a71, the edge of the scraper gear ring a74 is also provided with a ballast wheel a23, and the ballast wheel a23 is engaged with the scraper gear ring a74.
[0052] Alternatively, the output shaft of the reducer a72 is dire...

[0053] Embodiment 3
[0054] like Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown in the figure, the automatic cleaning range hood of the third embodiment is roughly the same as that of the first embodiment, the difference lies in that, in the second embodiment, a double main engine b10 is set in the casing b1, and a blower motor b64 is set, and the automatic cleaning device b7 includes a rotating The scraper b71, the fixed screen b21 and the speed reducer b72. The scraper b71 is in contact with the screen b21. The exhaust motor b31 shaft is connected to the first impeller b32 and then extends into the suction chamber b2 to connect to the reducer b72. The output shaft of the reducer b72 passes through the screen b21 and connects to the rotating scraper b71.
[0055] It also includes a lower suction chamber b8 arranged below the suction chamber b2, and the lower suction chamber b8 communicates with the suction chamber b2. The lower suction chambe...
