In one embodiment, the waste liquid containing cavity 233 and the second liquid storage cavity 231 are distributed in parallel, the cover 25 covers the waste liquid containing cavity 233 and one side of the second liquid storage cavity 231 away from the second connecting portion 21, the end face of the cover 25, which is close to the second connecting portion 21, is provided with a connecting groove 253, the shape of the connecting groove 253 is matched with that of one end, which is close to the cover 25, of the partition 29, one end of the partition 29 is arranged on the inner wall, which is close to the base 30, of the second liquid storage cavity 231, and the other end of the partition 29 is in clamping connection with the connecting groove 253. Through setting up lid 25 and the joint of baffle 29, can carry out spacingly to the removal of the circumference of lid 25, the fixed lid 25 of being convenient for. Of course, in other embodiments, the waste liquid chamber 233 and the second liquid chamber 231 can be distributed in other ways, such as up and down.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
