In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, fig. 1 is a perspective view of a cleaner 1 in which an embodiment of the present invention may be implemented, showing the main components of the cleaner 1, including a base 11, a front cleaning head 12, and a combing member 123. Wherein the cleaning chamber 111 and the dry garbage collecting chamber 112 are sequentially arranged in the base 11 from front to back, the cleaning chamber 111 and the dry garbage collecting chamber 112 are independent and separated from each other, the cleaning chamber 111 is transversely and rotatably connected with the front cleaning head 12, and the cleaning chamber 111 and the dry garbage collecting chamber 112 are communicated with each other through an ash throwing channel 1224; the combing member 123 is arranged on the upstream side in the dust conveying direction of the dust throwing passage 1224; the front cleaning head 12 includes:

a cylindrical front roller 125 rotatably connected to the cleaning chamber 111 in a lateral direction; and

wherein each of the rolling brush blades 121 includes a plurality of bristles extending radially outward; the combing member 123 is located on a rotation path of the drum brush blade 121 such that the bristles of the drum brush blade 121 are combed by the combing member 123 during periodic rotation with the front drum 125. So that when the bristles pass through the combing member 123, dirt such as hair, lint, filaments, etc. wound on the bristles can be intercepted by the combing member, and can be cut into finer dirt pieces by the bristles and carried forward again by the following bristles as the rolling brush blades continuously rotate, and then the dirt is thrown into the dry garbage collection chamber 112 through the dust throwing channel 1224 under the action of its own centrifugal force and inertia force, so as to be collected. Hereinafter and throughout the specification, the terms "front/front side" and "rear/rear side" should be understood as referring to the forward direction of the cleaner 1, specifically, the forward direction of the cleaner 1 is shown by the arrow H in fig. 1 and 5, wherein the direction indicated by the arrow H is "front/front side" and the direction opposite to the arrow H is "rear/rear side".

So that the roll brush blade can sweep the surface to be cleaned through the sweeping opening 1111.

With reference to fig. 4, 5 and 6, as a further modification, a front baffle 122 is disposed around the outer periphery of the front cleaning head 12; the front barrier 122 ends at the front side of the front drum 125 after passing at least 1/4 and at most 3/5 of circumference from the inlet of the ash-dumping channel 1224 in the direction of rotation of the front drum 125 to form the sweeping opening 1111 between the lower edge 1223 of the front barrier 122 and the bottom wall of the sweeping chamber 111.

In the embodiment shown in fig. 5, when the front cleaning head 12 is installed in the cleaning chamber 111, a cleaning gap is formed between the inner side of the front barrier 122 and the front drum 125, and a cleaning inlet 126 is formed between the rear side 1112 of the cleaning opening 1111 and the front drum 125; the comb member 123 is arranged in the sweeping gap.

In the embodiment shown in FIG. 4, the lower edge 1223 of the front baffle 122 defines the front side of the scavenge opening 1111; a scraper 124 is provided in the cleaning inlet 126, one end of the scraper 124 is connected to the rear side 1112 of the cleaning opening 1111, and the other end of the scraper 124 faces the surface S to be cleaned.
