The sewage chamber 101 is provided with a sewage flow port a and a gas flow port b, as shown in fig. 8 and 9, sewage (the flow path of which can be shown by the bold arrow in fig. 9) firstly passes through the suction port 103 at the bottom of the water tank 100 and then flows into the sewage chamber 101 through the sewage flow port a, the aperture of the through hole of the sewage flow port a can be reduced from large to small from top to bottom, the shape can be flattened by a circle, and the suction force can be increased from top to bottom, so that the sewage can be quickly sucked into the sewage chamber 101. And gas flow opening b on sewage chamber 101 can be located the top of sewage chamber 101, and gas (its circulation route can see thick dotted line arrow in fig. 9) is from the bottom up circulation, and gas in sewage chamber 101 can pass through gas flow opening b and discharge water tank 100, and similarly, gas flow opening b to down and go up through-hole aperture can become by big diminish, and the shape can become flat by the circle, and suction is to down and the gas of going up grow can flow out water tank 100 through gas flow opening b fast.

Example eight

As shown in fig. 11 to 12, in this embodiment, on the basis of the seventh embodiment, a secondary sewage chamber 105 is further disposed in the tank body 10 of the water tank 100, the secondary sewage chamber 105 can be detachably disposed in the tank body 10, specifically, the secondary sewage chamber 105 can be formed by a sewage tank, a sewage scraping member 31 can be further disposed at the rotating cleaning member 30, and the sewage scraping member abuts against and contacts with the outer surface of the rotating cleaning member 30

The structure and function of the water tank in the self-moving robot of this embodiment are the same as those in the fourth embodiment, and specific reference may be made to the description of the fourth embodiment, which is not described herein in detail.

The following describes the working process of the self-moving robot provided in this embodiment with reference to specific application scenarios:

application scenario 1

The user utilizes the remote control or starts from mobile robot's switch on the mobile robot, water tank from mobile robot can provide the washing liquid to ground or fixed cleaning member, for example, the clear water, the cleaning member is treated the cleaning surface and is soaked and clean before being fixed after soaking, rotate the stubborn spot that the cleaning surface was treated in rotatory continuous patting and friction of cleaning member, the realization is to the decomposition of stubborn spot, and fixed back cleaning member carries out comprehensive clean absorption to the stubborn spot after the decomposition, thereby can effectively clear up the stubborn spot of treating the cleaning surface, the cleaning performance from mobile robot has been improved.

Application scenario 2

From mobile robot at the during operation, the electricity switches on the solenoid valve in the water tank, make the washing liquid in the flourishing liquid chamber derive to fixed cleaning member, the cleaning surface is treated to the cleaning member and is soaked and clean before being fixed after soaking, rotate the stubborn spot that the cleaning surface was treated to rotatory the patting constantly and friction of cleaning member, the realization is to the decomposition of stubborn spot, and fixed back cleaning member carries out comprehensive clean absorption to the stubborn spot after the decomposition, thereby can effectively clear up the stubborn spot of treating the cleaning surface, the cleaning performance from mobile robot has been improved.

Application scenario 3

From mobile robot at the during operation, the electricity switches on the solenoid valve in the water tank, make the washing liquid in flourishing liquid chamber directly spray through fluid channel and treat clean surface, fixed cleaning member contact is sprayed the back of treating of washing liquid and is soaked on the clean face, and treat clean face and clean, it constantly beats and rubs the stubborn spot of treating the clean face to rotate the cleaning member rotation, the realization is to the decomposition of stubborn spot, and fixed back cleaning member carries out comprehensive clean absorption to the stubborn spot after the decomposition, thereby can effectively clear up the stubborn spot of treating the clean face, the cleaning performance from mobile robot has been improved.

Application scenario 4

From mobile robot in the course of the work, the fan rotates and produces the negative pressure, the sewage that will treat clean surface passes through the suction inlet of water tank bottom earlier, then the sewage circulation mouth through sewage chamber department inhales the sewage chamber, gaseous air current circulation mouth through the sewage chamber in the sewage chamber is from supreme discharge sewage chamber down, the aperture of sewage circulation mouth extremely up and by diminishing down, the aperture of air current circulation mouth is by diminishing by supreme down, effectively improved the circulation speed of sewage and gas, help improving mobile robot's work efficiency.

Application scenario 5

From mobile robot in the course of the work, the rotation cleaning member in the water tank constantly rolls and cleans treating clean surface, rotate the partial dirty water that cleaning member roll in-process will treat clean surface and get up, rotate the dirty water scraper next door and will rotate the sewage on the cleaning member and scrape down to the vice sewage chamber of dirty water scraper below, and treat that remaining sewage on the clean surface inhales in the dirty water chamber through the suction inlet of water tank department, improve sewage collection efficiency from this.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
