The working principle of the invention is as follows:

The user starts the hydraulic push rod 10 firstly, because the hydraulic push rod 10 can push the second rack 1001 downwards in an inclined way, in the process that the second rack 1001 is pushed transversely, because the third gear 7 is meshed with the second rack 1001, the third gear 7 is not meshed with the first rack 3 at first, because a certain section of the first rack 3 is not provided with teeth, the second rack 1001 can drive the third gear 7 to move transversely together until the two sides of the shaft end of the third gear 7 are contacted with the limiting ring 8, the limiting ring 8 can prevent the third gear 7 from sliding transversely, at the moment, the third gear 7 is meshed with the first rack 3, before the third gear 7 is locked, the second rack 1001 is pushed transversely to only push the fourth gear 12 to rotate in a meshed way, so that the air shielding plate 13 rotates, the air inlet channel at the front end of the range hood outer frame 1 is opened, so that air can enter normally, at the moment, the user can use the state of the range hood normally, only needs to drive the wind wheel 14 to rotate, the range hood is removed, the air can be absorbed by driving the wind wheel 14 to rotate, the air can be absorbed by the air, the air can slide along with the first rack 7, the first rack 5 is required to slide along the end face of the first rack 5, the end face of the range hood is cleaned, the third rack 5 is required to slide along with the first rack 7, the first rack 5, the end face is required to slide transversely, the third rack 7 is slid along with the first rack 5, the end face is required to be cleaned, the end face is completely, and the end face is slid by the third rack 5, and the end face is slid along with the first rack 5, and the end face is slid, and the end face is cleaned, and can be washed by the end 5, and can be a cleaner. The cleaning cotton roller 4 and the first gear 5 are driven to rotate, so that different surfaces of the cleaning cotton roller 4 are contacted with the front end surface of the outer frame 1 of the range hood, only one surface of the cleaning cotton roller is not contacted with the outer frame 1 of the range hood all the time during cleaning, and meanwhile, the second gear 6 can drive the reciprocating screw rod 17 to rotate in the rotating process, the reciprocating screw rod 17 can push the connecting sleeve 18 to do left and right reciprocating motion, so that the pushing rod 19 is pushed to slide back and forth in the piston cylinder 20, the piston in the cleaning cotton roller can slide back and forth, liquid is pumped out from the inner part of the liquid storage tank 24 through the liquid inlet pipe 21, the liquid can only be fed into the liquid inlet pipe 21, the liquid outlet pipe 22 can only be fed out, and the liquid can not be fed into the position of the cleaning cotton roller 4, and therefore a better scrubbing effect is achieved.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
