In this embodiment, the check valve 132 includes two semicircular check valve blades 132a, each check valve blade 132a is rotatably disposed in the air outlet 131 through a rotating shaft 132b, when each check valve blade 132a is aligned with the plane of the air outlet 131, the two check valve blades 132a are spliced into a circular piece to seal the air outlet 131, and when the two check valve blades 132a are perpendicular to the plane of the air outlet 131, the air outlet 131 is completely opened.
Further, a purifying chamber 14 is further disposed in the air outlet cover 111, an ozone generator 15 is disposed in the purifying chamber 14, the purifying chamber 14 is communicated with the inner chamber 110 through an air outlet 181, and an air outlet valve plate 18 capable of opening and closing the air outlet 181 is disposed on the air outlet 181, so that when the range hood is in a cooking state, the air outlet valve plate 18 closes the air outlet 181, and thus, the ozone generator 15 can be effectively prevented from being polluted by oil smoke. In this embodiment, the purifying chamber 14 is disposed adjacent to the air outlet chamber 13, that is, the purifying chamber 14 is also disposed above the inner chamber 110, and has a vertical side wall 133 shared with the air outlet chamber 13, an air inlet 1331 is formed on the vertical side wall 133, an air inlet valve plate 17 capable of opening and closing the air inlet 1331 is disposed in the air inlet 1331, and meanwhile, the air outlet 181 is disposed on the bottom wall of the purifying chamber 14 and is located above the air inlet port 121 of the fan 12.
In the present embodiment, the intake valve plate 17 and the exhaust valve plate 18 are linked to the check valve 132 by the transmission mechanism 16. When the check valve 132 rotates in the air outlet 131, the air inlet valve plate 17 can move relative to the air inlet 1331 to open and close the air inlet 1331, and the air outlet valve plate 18 can move relative to the air outlet 181 to open and close the air outlet 181, and when the check valve 132 closes the air outlet 131, both the air inlet 1331 and the air outlet 181 are opened, and when the air outlet 131 is opened, the air inlet valve plate 17 and the air outlet valve plate 18 close the air inlet 1331 and the air outlet 181, respectively.

In the non-cooking state, the fan 12 is in a low-speed running state (i.e. the rotation speed of the fan is lower than that in the cooking state), the check valve blades 132a close the air outlet 131 under the action of gravity (or related existing mechanisms such as springs, etc.), and the air inlet valve plate 17 and the air outlet valve plate 18 are respectively moved away from the air inlet 1331 and the air outlet 181 under the action of the transmission mechanism 16, and the air inlet 1331 and the air outlet 181 are respectively opened (as shown in fig. 7 and 9). In addition, in the non-cooking state, the fan 12 continues to operate (low-speed operation, wind power is smaller than that in the cooking state), under the action of the fan 12, air flow enters the purifying cavity 14 from the air outlet cavity 13 through the air inlet 1331, ozone gas generated by the ozone generator 15 is guided into the inner cavity 110 through the air outlet 181 under the driving of the air flow, the whole inner cavity 110 is quickly filled, the ozone gas is guided into the inner cavity of the fan 12 through the inner cavity 110, and then the ozone gas is guided into the air outlet cavity 13 through the rotation of the fan 12, so that the circulation of the ozone gas in the purifying cavity 14, the inner cavity 110, the inner cavity of the fan 12 and the air outlet cavity 13 is formed, the effective sterilization and deodorization are carried out on the whole interior of the range hood, and the dynamic balance of the effective concentration of ozone concentration in the inner cavity 110 can be kept in the whole sterilization and deodorization process under the action of the air flow generated by the fan 12. In addition, the air outlet 131 is closed in the sterilization and deodorization process of the range hood, so that ozone gas can be prevented from leaking to the outside, and the pollution and damage to the ozone generator 15 caused by the fact that oil smoke in a public flue is blown into the range hood through the air outlet 131 can be avoided.
Specifically, the driving mechanism 16 includes a driving gear 162 and a driving rod 161, one ends of two rotating shafts 132b are respectively exposed at one side of the air outlet 131, the driving gears 162 are two and are respectively fixed on the rotating shafts 132b, the driving rod 161 vertically penetrates through the purifying chamber 14, and both sides of the upper end of the driving rod are respectively provided with a tooth surface 161a capable of being meshed with the corresponding driving gear 162.
