In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1, an intelligent cleaning device 100 is shown in an embodiment of the present application, and it can be understood that the intelligent cleaning device is specifically a sweeping robot.

Continuing to refer to fig. 1 and fig. 2, the intelligent cleaning device 100 in the present application illustratively includes a base station 10 and a sweeper 20. The base station 10 is configured as a service device supporting the sweeper 20, and can provide cleaning, dirt collecting, charging, disinfecting, water replenishing and other services for the sweeper 20, so that the sweeper 20 has the capability of continuously working in an optimal state. The sweeper 20 is a direct implement for cleaning. For example, in the embodiment, the sweeper 20 can return to the base station 10 and perform sewage disposal operation, and the base station 10 discharges sewage collected by the sweeper 20 into a sewer or periodically cleans the sewage manually.

With continuing reference to fig. 3 and fig. 4, in particular, the base station 10 is provided with a driving mechanism 30; the sweeper 20 comprises a sewage container, and the sewage container is provided with an air hole 211 and a sewage discharge hole. In addition, the intelligent cleaning device 100 further comprises a switch mechanism 40, wherein the switch mechanism 40 is configured to be movably disposed and in driving fit with the driving mechanism 30, and the switch mechanism 40 is in open-close fit with the sewage draining hole and the air hole 211. When the driving mechanism 30 drives the opening and closing mechanism 40, the opening and closing mechanism 40 is activated to open the soil discharge hole and the air hole 211 simultaneously or sequentially.

For example, in this embodiment, the switch mechanism 40 is movably disposed through the blowoff hole and the air hole 211 and can open or close the blowoff hole and the air hole 211. Specifically, the sewage container in this embodiment includes a first sewage tank 21 and a second sewage tank 22, the sewage draining holes include a first sewage draining hole 212 and a second sewage draining hole 221, the first sewage tank 21 is disposed above the second sewage tank 22, the first sewage tank 21 is provided with an air hole 211 and a first sewage draining hole 212, and the second sewage tank 22 is provided with a second sewage draining hole 221 aligned with the first sewage draining hole 212. It is understood that the first soil discharge hole 212 is positioned right above the second soil discharge hole 221 in this embodiment. Of course, in other embodiments, the first wastewater tank 21 may be arranged in a horizontal or approximately horizontal position with the second wastewater tank 22, but it is necessary to ensure that the position of the first wastewater discharge hole 212 is higher than that of the second wastewater discharge hole 221 so as to ensure that wastewater in the first wastewater tank 21 can flow into the second wastewater tank 22 by itself under the action of gravity.

Specifically, the switch mechanism 40 is movably disposed through the first drain hole 212, the second drain hole 221 and the air hole 211; the switch mechanism 40 further comprises a valve mechanism 50, and the valve mechanism 50 is movably arranged at the air hole 211; when the driving mechanism 30 pushes the switch mechanism 40, the switch mechanism 40 is activated to open the sewage draining hole, i.e. the first sewage draining hole 212 and the second sewage draining hole 221 are opened and connected, and the switch mechanism 40 pushes the valve mechanism 50, so that the valve mechanism 50 opens the air hole 211.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the intelligent cleaning device 100 is applied to places such as families and the like, and can replace people to automatically complete cleaning work. Specifically, the sweeper 20 can leave the base station 10 and move according to the terrain, so as to complete the washing and mopping operation on the ground, and the sewage generated by washing and mopping is collected and scraped in the second sewage tank 22 and finally temporarily stored in the first sewage tank 21; after working for a period of time, when the first sewage tank 21 is full of sewage, the sweeper 20 automatically returns to the base station 10, after the sweeper 20 stops at the preset position, the driving mechanism 30 acts to push the switch mechanism 40 to move upwards to open and communicate the first sewage discharge hole 212 and the second sewage discharge hole 221 which are closed originally, and meanwhile, the switch mechanism 40 synchronously pushes the valve mechanism 50 to open the air hole 211, so that air in the external environment can flow into the first sewage tank 21, and the air pressure in the first sewage tank 21 is balanced with the external environment pressure. In this way, all the sewage in the first sewage tank 21 can flow through the second sewage draining hole 221 of the second sewage tank 22 through the first sewage draining hole 212 and finally flow into the sewage tank of the base station 10, so that the base station 10 can recycle the sewage of the sweeper 20, and the secondary working capacity of the sweeper 20 can be ensured.

Compared with the prior art, in the scheme, after the sweeper 20 returns to the base station 10, the driving mechanism 30 can synchronously open the first sewage discharge hole 212, the second sewage discharge hole 221 and the air hole 211, so that the internal pressure and the external pressure of the first sewage tank 21 are balanced, the sewage can be completely discharged, and the cleaning capability and the sanitary condition of the sweeper 20 are ensured.

With continued reference to fig. 4, in some embodiments, the sweeper 20 further includes a main frame 23, and the main frame 23 is provided with a pressing block 231. Specifically, the main body 23 is provided with a slide hole opposite to the air hole 211, a press block 231 is slidably disposed in the slide hole, the press block 231 is disposed between the first sewage tank 21 and the side wall of the sweeper 20, and the press block 231 is in press-contact with the sealing plate 52 to seal the air hole 211. The valve mechanism 50 includes a first push rod 51 and a sealing plate 52, the first push rod 51 is disposed on the sealing plate 52 and slidably disposed in the air hole 211, the first push rod 51 is in clearance fit with the hole wall of the air hole 211, and the first push rod 51 can drive the sealing plate 52 to open or close the air hole 211 by the sealing plate 52.

When the sweeper 20 works normally, it is necessary to ensure that the air hole 211 is blocked and not communicated with the external environment, and the first sewage discharge hole 212 is not communicated with the second sewage discharge hole 221. In order to enable the sealing plate 52 to reliably seal the air hole 211, the pressing block 231 is arranged in the sliding hole of the main machine 23, the pressing block 231 can be pressed on the upper surface of the sealing plate 52, the sealing plate 52 can be guaranteed to tightly press the air hole 211 under the action of the gravity of the pressing block 231, and the air hole 211 is prevented from being accidentally opened due to the fact that the sealing plate 52 is loosened due to vibration and the like in the moving process of the sweeper 20.

In order to prevent the pressing block 231 from falling off from the slide hole, a convex clamping body is convexly arranged on the upper part of the pressing block 231 located on the slide hole, and the convex clamping body is clamped at the upper hole end of the slide hole, so that the pressing block 231 can be prevented from falling off.

One end of the first push rod 51 passes through the air hole 211 and extends to the lower part of the air hole 211, so that the switch mechanism 40 can be conveniently abutted against the first push rod 51 to open the air hole 211. The first push rod 51 is in clearance fit with the hole wall of the air hole 211, so that after the sealing plate 52 is lifted to open the air hole 211, air in the external environment can flow into the first sewage tank 21 through the clearance to balance the pressure inside and outside the tank.

In addition to the above-described embodiment, the valve mechanism 50 further includes a first gasket 53, and the first gasket 53 is disposed on a side of the sealing plate 52 facing the air hole 211 and can be in sealing contact with the wall of the first waste water tank 21. Through setting up first sealing washer 53, thereby first sealing washer 53 pressurized produces deformation and can be sealed more tightly with gas pocket 211, prevents that the gas leakage in the external environment from into first sewage case 21 in, causes the sewage that the negative pressure environment in first sewage case 21 weakens or became invalid and can't retrieve the second sewage case 22 interior and scrape.

Alternatively, the first sealing ring 53 may be, but is not limited to, a rubber ring.

With reference to fig. 4, further, the first top rod 51 is provided with a limit buckle 54 protruding through the outer wall of the rod section of the air hole 211, and the limit buckle 54 can be in limit clamping connection with the wall of the first waste water tank 21. In this way, the stopper 54 is in contact with the wall of the first dirty water tank 21, and thus, when receiving the pushing force of the opening/closing mechanism 40, the first push rod 51 is prevented from moving upward and coming out of the air hole 211.

With continued reference to fig. 4, in some embodiments, the switch mechanism 40 includes a first push rod assembly 41 and a second push rod assembly 42, the first push rod assembly 41 includes a second push rod 411 and a second sealing ring 412, the second sealing ring 412 is disposed on the second push rod 411, the driving mechanism 30 can drive the second push rod assembly 42 to move, and the second push rod assembly 42 synchronously drives the second push rod 411, so that the second sealing ring 412 is away from the opening of the first sewage discharge hole 212 to open the first sewage discharge hole 212.

After the sweeper 20 returns to the preset position in the base station 10, the driving mechanism 30 pushes the second push rod 411 to ascend, the second push rod 411 can synchronously drive the second sealing ring 412 to ascend to open the first sewage draining hole 212, and meanwhile, the second push rod 411 synchronously pushes the first push rod 51 to ascend to open the air hole 211, so that air in the external environment flows into the first sewage tank 21 from the air hole 211, the pressure in the first sewage tank 21 is balanced with the pressure in the external environment, and a necessary condition for draining sewage is formed.

With reference to fig. 4, further, the first push rod assembly 41 further includes a bracket 413 and a first elastic member 414, the second push rod 411 is slidably disposed on the bracket 413, the first elastic member 414 abuts between the bracket 413 and the second push rod 411, and the bracket 413 is provided with a movable space for providing a moving stroke of the second push rod 311 so that the second sealing ring 412 can open the first drainage hole 212. In the sewage disposal process, the second top rod 411 rises to extrude the first elastic member 414 to generate compression deformation, and at the moment, the first elastic member 414 accumulates elastic potential energy; when the drainage is finished, the driving mechanism 30 resets and loses the pushing force on the first push rod assembly 41, the first elastic member 414 actively releases the elastic force, so as to push the second push rod 411 to move downwards to reset, and the first push rod 51 automatically falls down to enable the sealing plate 52 to block the air hole 211 again.

Alternatively, the first elastic member 414 may be, but is not limited to, any one of a spring, an elastic column, a spring plate, and the like. For example, the first elastic member 414 in the present embodiment is a spring.

With continuing reference to fig. 4 and fig. 5, in addition, on the basis of any of the above embodiments, the second push rod assembly 42 includes a third push rod 421 and a pushing member 422, the third push rod 421 is disposed in the second sewage discharge hole 221, the pushing member 422 is disposed in the third push rod 421 and is in clearance fit with an inner wall of the third push rod 421 to form a water passing cavity 423 communicated with the second sewage discharge hole 221, the driving mechanism 30 includes a pushing rod 34, and the pushing rod 34 can push the third push rod 421 to move, so that the third push rod 421 pushes the second push rod 411 to move, so that the first sewage discharge hole 212 is communicated with the water passing cavity 423.

Structurally, the second push rod assembly 42 is located between the first jack assembly and the drive mechanism 30. During the dirt discharging operation, the driving mechanism 30 firstly pushes the second pushing rod assembly 42 upwards, and then the second pushing rod assembly 42 synchronously pushes the first pushing rod assembly 41. That is, the driving mechanism 30 firstly pushes the pushing member 422 to move upward, and the pushing member 422 then drives the third push rod 421 to move upward and push the second push rod 411 upward, so that the first sewage discharge hole 212, the water passing cavity 423 and the second sewage discharge hole 221 are sequentially communicated, and since the air hole 211 is also synchronously opened, sewage in the first sewage tank 21 can finally flow into the sewage tank of the main machine 23 to be collected after flowing through the first sewage discharge hole 212, the water passing cavity 423 and the second sewage discharge hole 221. The whole structure is simple in composition and movement mode, sewage flows through the short pipe, the sewage is discharged to the base station 10 quickly, and the sewage recovery efficiency is improved.

It can be understood that the third push rod 421 is a hollow rod, and the diameter of the pushing member 422 is smaller than that of the hollow cavity of the third push rod 421, so that the pushing member 422 is inserted into the third push rod 421 to form a water passing cavity 423, and the water passing cavity 423 facilitates the inflow of sewage after the sewage flows into the second sewage tank 22, and also makes the structure of the second push rod assembly 42 very compact, occupies a small space, and is convenient to install.

Further, the second push rod assembly 42 further includes a water guiding cylinder 424, the water guiding cylinder 424 is disposed on the third push rod 421 and is opposite to the first sewage draining hole 212, and the water guiding cylinder 424 is used for guiding sewage flowing through the first sewage draining hole 212 into the water passing cavity 423. The water guide cylinder 424 is closely contacted with the lower hole end of the first sewage discharge hole 212, and can guide all the sewage flowing through the first sewage discharge hole 212 into the water passing cavity 423 to be discharged.

The opposite ends of the water guide cylinder 424 are respectively a mounting end and a joint end, the mounting end is arranged on the third push rod 421, the third push rod 421 drives the water guide cylinder 424 to abut against the side wall of the first sewage tank 21, and the water guide cylinder 424 deforms to enable the joint end to be in sealing connection with the first sewage draining hole 212. Specifically, the water guide cylinder 424 is made of a flexible and elastic material (such as rubber), and when the water guide cylinder 424 deforms under the action of an extrusion force, the first sewage discharge hole 212 can be more reliably sealed, so that the sewage is prevented from escaping into the device and causing pollution.

Referring to fig. 4, further, a hollow column 425 is protruded from an outer periphery of the second drainage hole 221, the third push rod 421 is slidably disposed in the hollow column 425, and a second elastic member 426 is disposed between the third push rod 421 and the hollow column 425. The hollow column 425 plays a role in guiding and limiting the vertical sliding of the third push rod 421, and ensures that the third push rod 421 and the second push rod 411 are aligned and abutted accurately. The second elastic member 426 enables the third push rod 421 to automatically reset, and the third push rod 421 does not push the second push rod 411 and the first push rod 51 on line, so as to realize the automatic closing of the air hole 211, the first sewage discharge hole 212 and the second sewage discharge hole 221.

In addition, the second push rod assembly 42 further comprises a third sealing ring 427, and the third sealing ring 427 is disposed outside the third push rod 421 and can be in sealing engagement with the port of the hollow column 425. When the third push rod 421 is not pushed up, the third sealing ring 427 can seal the gap between the third push rod 421 and the hollow column 425, so as to prevent sewage from flowing out of the second sewage discharge hole 221 to the ground through the hollow cavity of the third push rod 421 when sewage is not discharged, and prevent the sewage from flowing to cause sanitary problems and soaking wooden floors and furniture.

Further, the driving mechanism 30 further includes a third elastic member 35, and the third elastic member 35 abuts between the jacking rod 34 and the sidewall of the base station 10. When the rack moves back and resets, the third elastic element 35 can automatically push the jacking push rod 34 to descend and reset.
