The filter assembly 30 can have an arc-shaped bottom surface or a rectangular bottom surface, and the bottom surface of the filter assembly 30 is spaced from the bottom surface of the receiving groove 201. When the oil smoke passes through the filter assembly 30, the water vapor and grease contained in the oil smoke are captured by the filter holes, and condensed and drip into the water guide 20, and then flow from the water guide 20 to the water collection box 40 for collection.

[0046] The water collecting box 40 can be detachably connected to the fan assembly 10 by means of threaded connection, snap connection, etc. The water collecting box 40 and the water guide 20 are connected through the fan assembly 10, and the condensed water flows from the water guide 20 along the bottom surface of the receiving groove 201 through the fan assembly 10 into the water collecting box 40.

[0056] Specifically, the angle formed by the third side wall 26 and the first wall 27 and the second wall 28 can be a right angle, an acute angle or an obtuse angle. The fan assembly 10 can contact the first wall 27 or the second wall 28. When the first wall 27 contacts the fan assembly 10, the area of ​​the first side wall 24 can be the sum of the areas of the second side wall 25 and the third side wall 26, or it can be greater than the sum of the areas of the second side wall 25 and the third side wall 26; when the second wall 28 contacts the fan assembly 10, the area of ​​the second side wall 25 can be the sum of the areas of the first side wall 24 and the third side wall 26, or it can be greater than the sum of the areas of the first side wall 24 and the third side wall 26.
