Referring to fig. 2, a schematic structural diagram of a cleaning apparatus with a negative pressure airflow channel according to embodiment 2 of the present invention is shown. The cleaning device provided by the embodiment comprises a steam solid-state garbage separation bin 4 and a rear wiper strip assembly 5 which are attached to each other in a front-rear manner, as well as the cleaning device provided by the embodiment 1. The cleaning device provided by the embodiment is different from the cleaning device provided by the embodiment 1 in that the cleaning device provided by the embodiment further comprises a rolling cleaning component 3 and a water adding component 6.

Wherein, add clear water subassembly 6 and locate roll cleaning assembly 3 top, roll cleaning assembly 3 includes axis of rotation 31 and cleaning member, cleaning member set up in axis of rotation 31 is last.

The working principle (process) of the cleaning device with the negative pressure airflow channel provided by the embodiment is as follows:

when the cleaning device moves forwards (the movement direction of the cleaning device is shown as the direction of arrow a in the figure), a negative pressure airflow is generated under the action of the negative pressure air suction and water storage device, and the negative pressure airflow sequentially flows through a negative pressure airflow channel formed by communicating the first suction port 4100, the front suction channel 410, the front suction cavity 40, the rear suction cavity 50, the second suction port 5100 and the rear suction channel 510 (the direction of the negative pressure airflow is shown as the direction of the arrow of the mixture of the water vapor and the solid matter, and the mixture of the water vapor and the small solid matter in the figure). At the same time, the cleaning member (mop cloth 32 b) of the rolling cleaning assembly 3 is continuously filled with clean water through the clean water adding assembly 6 (the water adding direction is shown as an arrow C direction in the figure), so that the mop cloth 32b is wetted. The mop cloth 32B is rotated (the rotation direction is shown by arrow B) by the rotating shaft 31 to rub against the floor surface for cleaning, so that the mop cloth 32B can mop the floor surface. As the cleaning device moves forward, the mixture of moisture and solid on the floor at the front end of the rolling cleaning assembly 3 is introduced into the first suction port 4100 by the rolling mop 32b, and the moisture is vaporized in the first vaporization region 491 by the negative pressure air flow and the front wiper strip 400, so that the mixture of moisture and solid is formed and introduced into the front suction chamber 40 through the front suction passage 410 by the negative pressure air flow and the rotation of the rolling mop 32b. In addition, the mop cloth 32b is adhered to the moisture and the solid on the surface of the mop cloth 32b after mopping, part of the moisture and the solid is thrown out of the mop cloth 32b to the front suction chamber 40 due to centrifugal force, and the rest of the moisture and the solid is in contact with the scraper 48 as the mop rotates, so that the moisture is scraped by the scraper 48 and the moisture is vaporized in the fourth vaporization region 494, thereby forming a mixture of the moisture and the solid into the front suction chamber 40. The large solid matters which cannot pass through the air vent 401 in the mixture entering the front suction cavity 40 are trapped in the front suction cavity 40, while the water vapor and the small solid matters pass through the air vent 401 under the action of the negative pressure air flow and are vaporized in the second vaporizing region 492 to form a new mixture, and the new mixture entering the rear suction cavity 50 enters the negative pressure air suction water storage device through the second suction port 5100 and the rear suction channel 510.
