The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

The present application provides a base station of a cleaning device and a cleaning system, which are described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Cleaning devices such as a cleaning machine, a floor cleaning machine, a cleaning robot and the like are widely used in various fields due to the advantages of labor saving, convenience and the like. Because cleaning equipment is usually semi-automatic, often need the manual sewage that the cleaning equipment produced of people after finishing using, lead to cleaning equipment's use threshold higher, and the clearance process is loaded down with trivial details, complicated. Currently, there are base stations on the market that can automatically clean cleaning equipment. The base station integrates the functions of automatic water changing, automatic cleaning equipment and the like, and the cleaning equipment and the base station are matched to realize automatic water changing actions, so that the appearance of the new functions is greatly convenient for users. However, currently, the base station only allows a water tank with a larger volume to be arranged, and the base station still needs users to change water regularly. The water in the base station water tank is placed for a long time and is easy to breed bacteria and generate peculiar smell, and the health of users is threatened.

Currently, a base station with an automatic water changing function exists in the market, sewage can be generated by cleaning equipment in the cleaning process, and the base station can automatically discharge the sewage generated by the cleaning equipment to a sewer pipe in a user home environment. Sewage is usually discharged by self gravity, and because the solid content in the sewage is high, a large amount of water is often required to have enough potential energy to flush the sewage into a sewer pipe, the outlet and the inlet of a sewage pipeline are usually required to have a high height difference, and a large amount of water is required to flush. Moreover, due to the fact that the viscosity of sewage generated by the cleaning equipment is high, and due to the fact that the friction force of the pipe wall, the surface tension of the sewage and other factors influence, the flow speed of the sewage is low in the sewage discharging process, the sewage is easy to adhere to the inner wall of a sewage discharging pipeline of a base station or the inner wall of a sewer pipe, the sewage cannot be thoroughly discharged, and even the problem of pipeline blockage is easy to cause.

In view of this, the embodiments of the present application provide a base station of a cleaning device and a cleaning system, which can remove dirt as much as possible, and reduce the risk of blockage of a pipeline assembly and a sewer pipe. As will be described in detail below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a cleaning system according to the present application.

In one embodiment, the cleaning device 10 may be a floor washer or the like. The cleaning device 10 includes a main unit and a brush, and a user holds the main unit and pushes the brush to move on a surface to be cleaned, so that the brush cleans a passing area and recovers dirt generated in the cleaning process. Alternatively, the cleaning device 10 may be a cleaning robot or the like. The cleaning device 10 is capable of moving on the surface to be cleaned by itself to clean the area through which it passes and to recover the dirt produced during cleaning.

The base station 20 is applied to assist the cleaning device 10 in cleaning. The embodiment of the present application is described by taking the example that the base station 20 is applied to the automatic discharging and cleaning device 10 to generate the dirt, which is only needed for discussion, and thus the function of the base station 20 is not limited. It should be noted that the dirt generated by the cleaning device 10 should be understood to include the dirt recovered by the cleaning device 10 during the cleaning process, and may further include the dirt generated by cleaning (i.e., self-cleaning) the cleaning device 10 itself. Further, the cleaning device 10 comprises a dirt storage member 11 for storing dirt. The dirt recovered from the surface to be cleaned by the cleaning device 10 and the dirt recovered by the cleaning device 10 by self-cleaning are stored in the dirt storage member 11. The dirt storage part 11 is provided with a sewage outlet 12, and the sewage outlet 12 is used for discharging dirt, so that the purpose of cleaning the dirt storage part 11 is achieved.

Further, the base station main body 21 also serves to carry the cleaning device 10. The base station main body 21 has a carrying portion 212, and when the cleaning device 10 is returned to the base station 20, the cleaning device 10 is carried on the carrying portion 212, and thus the dirt generated by the cleaning device 10 is automatically discharged through the base station 20. As shown in fig. 4, the base station main body 21 may further include a dirt collecting tank 211, and the dirt collecting tank 211 is specifically located at the carrying portion 212, and the dirt collecting tank 211 is used for collecting dirt generated when the cleaning device 10 is cleaned.

The drain assembly 23 is configured to output a drain fluid to the pipe assembly 22 to drain the dirt in the pipe assembly 22 to the sewer pipe 30 through the drain fluid. In this way, the present embodiment outputs the blowdown fluid to the pipeline assembly 22 through the blowdown assembly 23 to pressurize and discharge the dirty in the pipeline assembly 22 to the sewer pipe 30, so that the dirty can be discharged as much as possible, and the risk of clogging of the pipeline assembly 22 and the sewer pipe 30 can be reduced. Compared with the prior art, the embodiment can save the water for flushing the dirt, does not completely rely on the gravitational potential energy of the dirt to carry out the dirt discharge, is favorable for the overall design of the base station 20 to be smaller, and further improves the flexibility of the arrangement of the base station 20.

It should be noted that the sewage fluid may be a gaseous fluid, a liquid fluid, or a mixture of a gaseous fluid and a liquid fluid, which is not limited herein.

During the process of creating the negative pressure environment by the sewage assembly 23, the second sewage collection control valve 2242 always blocks the flow path between the sewage collection tank 211 and the transfer member 221, and at least after the sewage assembly 23 completes creating the negative pressure environment, the sewage control valve 225 blocks the flow path between the transfer member 221 and the sewer pipe 30.

The drain assembly 23 of the embodiments of the present application is described below.

Please continue to refer to fig. 1. In one embodiment, based on the example of the piping assembly 22 including the first sewage collection control valve 2241 and the sewage control valve 225 described above, the sewage assembly 23 includes the vacuum generating element 231, the inflow pipe 232, and the outflow pipe 233. The vacuum generating element 231 is connected to the transfer member 221 through the inflow pipe 232, and the vacuum generating element 231 is connected to the drain pipe 222 through the outflow pipe 233. Specifically, the outlet pipe 233 is connected to the drain pipe 222 between the drain control valve 225 and the drain pipe 30. The vacuum generating element 231 is used for pumping the gas in the transfer member 221 to the drain pipe 222 for discharging, so as to create a negative pressure environment inside the transfer member 221.

The working procedure of the base station 20 in this embodiment is as follows: first, the first sewage collecting control valve 2241 is controlled to block a flow path between the cleaning device 10 and the intermediate transfer member 221 and the sewage control valve 225 is controlled to block a flow path between the intermediate transfer member 221 and the sewer pipe 30, the vacuum generating element 231 withdraws the gas inside the intermediate transfer member 221 through the inflow pipe 232, and discharges the withdrawn gas to the sewage pipe 222 through the outflow pipe 233 to create a negative pressure environment inside the intermediate transfer member 221 so that the inside of the intermediate transfer member 221 has a target vacuum degree; the sewage discharging assembly 23 is used for completing the creation of the negative pressure environment, and the first sewage collecting control valve 2241 is used for blocking the flow path between the cleaning device 10 and the transfer piece 221 and the sewage discharging control valve 225 is used for blocking the flow path between the transfer piece 221 and the sewer pipe 30, so that the vacuum degree in the transfer piece 221 is maintained; then, the first sewage collection control valve 2241 is controlled to conduct a flow path between the cleaning device 10 and the transferring member 221, so that the sewage generated by the cleaning device 10 is discharged to the transferring member 221 at least under the action of the negative pressure; then, the sewage control valve 225 is controlled to conduct the flow path between the transit member 221 and the sewer pipe 30 so that the sewage in the transit member 221 is discharged to the sewage pipe 222; thereafter, the first sewage collection control valve 2241 is maintained to be communicated with the flow path between the cleaning device 10 and the transit member 221, the sewage assembly 23 outputs the sewage to the sewage pipe 222 to discharge the sewage in the sewage pipe 222 to the sewer pipe 30 through the sewage, and at the same time, the sewage control valve 225 blocks the flow path between the transit member 221 and the sewer pipe 30 to prevent the sewage from flowing to the transit member 221, thereby facilitating the reliable discharge of the sewage in the sewage pipe 222 to the sewer pipe 30 through the sewage.

Further, referring also to FIG. 7, the drain assembly 23 further includes a vacuum hold valve 234. The vacuum maintaining valve 234 is disposed on the inlet pipe 232 and/or the outlet pipe 233, and the vacuum maintaining valve 234 is used for selectively blocking the flow path of the sewage assembly 23, specifically for blocking the flow path of the sewage assembly 23 after the vacuum generating element 231 completes creating the negative pressure environment, that is, blocking the flow path formed by the vacuum generating element 231, the inlet pipe 232 and the outlet pipe 233. Fig. 7 exemplarily shows a case where the vacuum holding valve 234 is provided to the inflow pipe 232.

In the above manner, the present embodiment can maintain the vacuum degree inside the relay member 221 after the vacuum generating element 231 completes the creation of the negative pressure environment by providing the vacuum maintaining valve 234. In other words, the present embodiment allows the negative pressure environment to be created in advance inside the relay 221 before the cleaning apparatus 10 is returned to the base station 20, so that the dirt discharge operation can be performed immediately without waiting for the vacuum generating element 231 to create the negative pressure environment when the cleaning apparatus 10 is returned to the base station 20. In this embodiment, the vacuum generating element 231 with high power is not needed to be selected for efficiently creating the negative pressure environment, i.e. the power requirement for the vacuum generating element 231 is low, which is beneficial to reducing the cost of the vacuum generating element 231.

Of course, the present embodiment also allows the vacuum generating element 231 to be controlled to create a negative pressure environment inside the transferring member 221 after the cleaning apparatus 10 returns to the base station 20, which is not limited herein.

In an alternative embodiment, the present embodiment is different from the above-described embodiment in that the vacuum generating element 231 can block the flow path of the sewage assembly 23 after the creation of the negative pressure environment is completed, so as to omit the vacuum holding valve 234. Specifically, the vacuum generating element 231 itself may be provided with a one-way conduction element such as a one-way valve, which allows gas to flow from the inflow pipe 232 through the vacuum generating element 231 to the outflow pipe 233, while restricting gas from flowing from the outflow pipe 233 through the vacuum generating element 231 to the inflow pipe 232.

In this way, the vacuum generating element 231 of the present embodiment is equipped with the unidirectional conductive element itself to allow the vacuum generating element 231 to create a negative pressure environment inside the relay member 221 while restricting the reverse flow of the gas into the relay member 221, so that the vacuum generating element 231 of the present embodiment can maintain the vacuum degree inside the relay member 221 after the creation of the negative pressure environment is completed.

In the case where the vacuum holding valve 234 is not provided and the vacuum generating element 231 itself is not provided with a unidirectional flow-through element, when the first sewage collection control valve 2241 blocks the flow path between the cleaning device 10 and the intermediate member 221 and the sewage control valve 225 blocks the flow path between the intermediate member 221 and the sewer pipe 30, the vacuum degree of the internal environment of the intermediate member 221 can be maintained for a short period of time. Therefore, in this case, it is necessary to control the vacuum generating element 231 to create a negative pressure environment inside the relay 221 after the cleaning apparatus 10 is returned to the base station 20.

The outlet pipe 233 is connected between the third sewage collection control valve 2243 and the sewer pipe 30, and the third sewage collection control valve 2243 serves to block a flow path between the cleaning device 10 and the outlet pipe 233 when the outlet pipe 233 outputs sewage fluid. Fig. 8 schematically shows that the vacuum generating element 231 is connected to the drain pipe 222 via a drain pipe 233.

The working procedure of the base station 20 in this embodiment is as follows: first, the third sewage collection control valve 2243 is controlled to conduct a flow path between the cleaning device 10 and the sewer pipe 30, and sewage generated by the cleaning device 10 is discharged to the sewage pipe 222 through the transit member 221; thereafter, the third pollution control valve 2243 is controlled to block the flow path between the cleaning device 10 and the outlet pipe 233, the vacuum generating element 231 draws in the gas of the external environment through the inlet pipe 232 therein, and then the vacuum generating element 231 outputs the drawn-in gas to the drain pipe 222 through the outlet pipe 233 to form a drain fluid, so that the dirty in the drain pipe 222 is discharged to the drain pipe 30 through the drain fluid.

Referring to fig. 9, fig. 9 is a schematic structural diagram of an eighth embodiment of the cleaning system of the present application.

In one embodiment, based on the example of the piping assembly 22 including the first sewage collection control valve 2241 and the sewage disposal control valve 225, the sewage disposal assembly 23 includes a vacuum generating element 231 and a flow-through pipe 235, and the vacuum generating element 231 is connected to the transfer member 221 through the flow-through pipe 235.

The vacuum generating element 231 of the present embodiment has a function of switching between the forward and reverse power supply, and the vacuum generating element 231 is switched between the forward and reverse power supply states by switching between the forward and reverse power supply states, thereby switching the vacuum generating element 231 between the first and second states.

Referring to fig. 10, fig. 10 is a schematic structural diagram of a ninth embodiment of the cleaning system according to the present application.

In one embodiment, based on the example of the piping assembly 22 including the first pollution control valve 2241 and the pollution control valve 225 described above, the pollution assembly 23 includes the vacuum generating element 231. The vacuum generating element 231 has an inlet end 2311 and an outlet end 2312. The drain assembly 23 also includes a flow path switching valve 236. The flow path switching valve 236 is connected to the inflow end 2311 and the outflow end 2312, respectively, and the flow path switching valve 236 is also connected to the relay 221. The flow path switching valve 236 further has a connection end 2361 connected to the external environment.

The flow path switching valve 236 is configured to be switchable between a third state and a fourth state. The flow path switching valve 236 in the third state conducts the inflow end 2311 and the transit member 221 and conducts the outflow end 2312 and the connection end 2361, so that the vacuum generating element 231 pumps out the gas in the transit member 221 and discharges the gas to the external environment, thereby creating a negative pressure environment inside the transit member 221; the flow path switching valve 236 in the fourth state communicates the inflow end 2311 with the connection end 2361 and the outflow end 2312 with the relay member 221, so that the vacuum generating element 231 outputs the sewage fluid to the sewage pipe 222 through the relay member 221.

In this way, by providing the flow path switching valve 236, the present embodiment does not require the vacuum generating element 231 to have a function of switching between the forward and reverse power supply, and can adapt to more types of vacuum generating elements 231, thereby facilitating the selection of the types of the vacuum generating elements 231.

In one embodiment, to reduce the risk of damage to the vacuum generating element 231 due to dirt intrusion into the vacuum generating element 231, the vacuum generating element 231 of the present embodiment is located on the side of the transfer member 221 remote from the drain pipe 222. The dirt is deposited on the bottom of the relay member 221 by its own weight, so that the risk of the dirt entering the vacuum generating device 231 can be reduced.

In one embodiment, the drain assembly 23 further includes a filter element 237. The filter element 237 is in fluid communication with the vacuum generating element 231, and the filter element 237 is configured to filter the gas exhausted from the vacuum generating element 231 to the external environment, so as to avoid the odor in the pipeline assembly 22 from diffusing to the external environment as much as possible, which is beneficial to improving the use experience of the user.

For example, for the embodiment described above in which the drain assembly 23 includes the vacuum generating element 231 and the flow-through tube 235, one port of the vacuum generating element 231 is connected to the flow-through tube 235 and the other port is connected to the filter element 237, as shown in fig. 9; for the embodiment described above in which the drain assembly 23 includes the vacuum generating element 231 and the flow path switching valve 236, the filter element 237 is connected to the connecting end 2361 of the flow path switching valve 236, as shown in fig. 10.

Referring to fig. 11, fig. 11 is a schematic structural view of a tenth embodiment of the cleaning system of the present application.

In one embodiment, based on the example of the piping assembly 22 including the first pollution control valve 2241 and the pollution control valve 225 described above, the pollution assembly 23 includes the vacuum generating element 231. The vacuum generating element 231 is provided to the drain pipe 222. The vacuum generating element 231 itself allows passage of gaseous, liquid, solid, etc. media, so that dirt in the drain pipe 222 can be discharged through the vacuum generating element 231 to the drain pipe 30. The vacuum generating element 231 is used for pumping the gas in the transit member 221 to the drain pipe 222 for discharge, so as to create a negative pressure environment inside the transit member 221. The vacuum generating element 231 may be various rotor pumps, gear pumps, peristaltic pumps, etc.

The working procedure of the base station 20 in this embodiment is as follows: first, the first sewage collection control valve 2241 is controlled to block a flow path between the cleaning device 10 and the transit member 221 and the sewage control valve 225 is controlled to conduct a flow path between the transit member 221 and the sewer pipe 30, and the vacuum generating element 231 pumps the gas in the transit member 221 to the sewer pipe 222 to be discharged, so that a negative pressure environment is created inside the transit member 221, so that the inside of the transit member 221 has a target vacuum degree; the sewage discharging assembly 23 is used for completing the construction of the negative pressure environment, keeping the first sewage collecting control valve 2241 to block the flow path between the cleaning device 10 and the transfer piece 221, and controlling the sewage discharging control valve 225 to block the flow path between the transfer piece 221 and the sewer pipe 30, so that the vacuum degree in the transfer piece 221 is kept; then, the first sewage collection control valve 2241 is controlled to conduct a flow path between the cleaning device 10 and the transferring member 221, so that the sewage generated by the cleaning device 10 is discharged to the transferring member 221 at least under the action of the negative pressure; then, the sewage control valve 225 is controlled to conduct the flow path between the transfer member 221 and the sewer pipe 30, the vacuum generating element 231 pumps the sewage in the transfer member 221 to the sewage pipe 222, and the sewage fluid is output to the sewage pipe 222 during the sewage pumping process of the vacuum generating element 231, so that the sewage in the sewage pipe 222 is discharged to the sewer pipe 30 through the sewage fluid.

In addition, in the present embodiment, since the vacuum generating element 231 is disposed at the drain pipe 222, the first sewage collection control valve 2241 blocks the flow path between the cleaning device 10 and the relay member 221 and the sewage control valve 225 blocks the flow path between the relay member 221 and the sewer pipe 30, so that the vacuum degree inside the relay member 221 can be maintained after the vacuum generating element 231 completes the creation of the negative pressure environment. In other words, the present embodiment allows the negative pressure environment to be created in advance inside the relay member 221 before the cleaning apparatus 10 is returned to the base station 20, so that the dirt in the cleaning apparatus 10 can be discharged to the relay member 221 without waiting for the vacuum generating element 231 to create the negative pressure environment when the cleaning apparatus 10 is returned to the base station 20. In this embodiment, the vacuum generating element 231 with high power is not needed to be selected for efficiently creating the negative pressure environment, i.e. the power requirement for the vacuum generating element 231 is low, which is beneficial to reducing the cost of the vacuum generating element 231. Of course, the present embodiment also allows the vacuum generating element 231 to be controlled to create a negative pressure environment inside the transferring member 221 after the cleaning apparatus 10 returns to the base station 20, which is not limited herein.

Further, a drain control valve 225 is provided between the vacuum generating element 231 and the drain pipe 30.

Referring to fig. 12, fig. 12 is a schematic structural diagram of an eleventh embodiment of the cleaning system of the present application.

In an embodiment, the difference between the present embodiment and the above-described embodiment is that the present embodiment does not provide the first sewage collection control valve 2241 and the sewage discharge control valve 225, and the sewage generated from the cleaning device 10 is pumped by the vacuum generating element 231 alone to be discharged to the sewage pipe 30 through the first sewage collection pipe 2231, the transfer member 221 and the sewage discharge pipe 222 in sequence.

In one embodiment, the base station 20 further includes a shredding element 238, as shown in FIG. 11. The mashing element 238 is disposed on the drain pipe 222, and the mashing element 238 is used for mashing dirt in the drain pipe 222, so as to further reduce the risk of clogging of the drain pipe 222 and the drain pipe 30.

Further, for the embodiment in which the vacuum generating element 231 is provided to the drain pipe 222, the mashing element 238 is located between the relay member 221 and the vacuum generating element 231. In this way, before the dirt passes through the vacuum generating element 231, particles, hair fibers, and other easily entangled objects in the dirt, which have a large volume, are crushed by the crushing element 238, so that the risk of clogging of the drain pipe 222 and the drain pipe 30 can be reduced, and the risk of damage to the vacuum generating element 231 can be reduced.

Please continue to refer to fig. 4. In one embodiment, the line assembly 22 further includes a level sensor 227. The liquid level sensor 227 is disposed inside the transfer member 221, and the liquid level sensor 227 is used for detecting a liquid level of dirt inside the transfer member 221. The liquid level sensor 227 can detect the liquid level of the dirt inside the transfer member 221 in real time under the condition that the design volume of the transfer member 221 is small or the dirt inside the transfer member 221 contains a large amount of foam, so as to reduce the risk of overflowing into the vacuum generating element 231 due to the overhigh dirt level inside the transfer member 221, and can also be applied to indirectly judging whether the control valve is normal or not.

It should be noted that the cleaning device 10 and the base station 20 of the present embodiment are described in detail in the above embodiments, and will not be described again here.

The technical scheme provided by the embodiment of the application is explained below in combination with a specific application scene.

Application scenario one:

as shown in fig. 1, the cleaning device 10 is a floor scrubber. After the cleaning device 10 returns to the base station 20, the dirt storage 11 of the cleaning device 10 interfaces with the first dirt collection tube 2231. Then, the first sewage collection control valve 2241 is controlled to block the flow path between the cleaning device 10 and the transit 221 and the sewage control valve 225 is controlled to block the flow path between the transit 221 and the sewer pipe 30, the vacuum generating element 231 withdraws the gas inside the transit 221 through the inflow pipe 232, and the withdrawn gas is discharged to the sewage pipe 222 through the outflow pipe 233 to create a negative pressure environment inside the transit 221; after that, the drain port 12 is opened, and the sewage in the sewage storage member 11 is discharged to the first sewage collection pipe 2231 under the self-gravity; then, the first dirty control valve 2241 is controlled to conduct the flow path between the cleaning apparatus 10 and the transfer member 221, and the dirty in the first dirty pipe 2231 is discharged to the transfer member 221 under the action of self gravity and negative pressure; then, the sewage control valve 225 is controlled to conduct the flow path between the transit member 221 and the sewer pipe 30 so that the sewage in the transit member 221 is discharged to the sewage pipe 222; thereafter, the first sewage collection control valve 2241 is maintained to be communicated with the flow path between the cleaning device 10 and the transit member 221, while the sewage control valve 225 blocks the flow path between the transit member 221 and the sewer pipe 30, and the vacuum generating element 231 continues to pump the gas inside the transit member 221 to the sewage pipe 222 to form a sewage fluid, so that the sewage in the sewage pipe 222 is discharged to the sewer pipe 30 through the sewage fluid. After the completion of the soil discharge, the first soil collecting control valve 2241 and the soil discharging control valve 225 are controlled to be closed, and the vacuum generating device 231 is controlled to stop working, waiting for the next working cycle.

And (2) an application scene II:

as shown in fig. 2, the cleaning device 10 is a floor scrubber. After the cleaning device 10 is returned to the base station 20, the dirt storage 11 of the cleaning device 10 is plugged into the first dirt collection tube 2231, and the seal 226 forms a seal between the first dirt collection tube 2231 and the cleaning device 10. The vacuum generating element 231 itself is provided with a one-way conduction element to allow the vacuum generating element 231 to create a negative pressure environment inside the relay member 221 while restricting the reverse flow of gas into the relay member 221, so that the degree of vacuum inside the relay member 221 can be maintained. In other words, the base station 20 may previously create the negative pressure environment inside the relay 221 before the cleaning apparatus 10 returns to the base station 20, so that the dirt discharge operation can be performed immediately without waiting for the vacuum generating element 231 to create the negative pressure environment when the cleaning apparatus 10 returns to the base station 20.

Specifically, the first sewage collection control valve 2241 is controlled to block a flow path between the cleaning device 10 and the transit member 221 and the sewage control valve 225 is controlled to block a flow path between the transit member 221 and the sewer pipe 30, the vacuum generating element 231 withdraws the gas inside the transit member 221 through the inflow pipe 232, and the withdrawn gas is discharged to the sewage pipe 222 through the outflow pipe 233 to create a negative pressure environment inside the transit member 221 in advance. The vacuum generating member 231 restricts the reverse flow of the gas into the relay member 221, and can maintain the vacuum degree inside the relay member 221 after the creation of the negative pressure environment is completed.

After the cleaning device 10 is returned to the base station 20, the drain 12 of the dirt container 11 on the cleaning device 10 is docked with the first dirt collection pipe 2231. After that, the drain port 12 is opened, and the sewage in the sewage storage member 11 is discharged to the first sewage collection pipe 2231 under the self-gravity; then, the first dirty control valve 2241 is controlled to conduct the flow path between the cleaning apparatus 10 and the transfer member 221, and the dirty in the first dirty pipe 2231 is discharged to the transfer member 221 under the action of self gravity and negative pressure; then, the sewage control valve 225 is controlled to conduct the flow path between the transit member 221 and the sewer pipe 30 so that the sewage in the transit member 221 is discharged to the sewage pipe 222; thereafter, the first sewage collection control valve 2241 is maintained to be communicated with the flow path between the cleaning device 10 and the transfer member 221, and simultaneously the sewage control valve 225 is controlled to block the flow path between the transfer member 221 and the sewer pipe 30, and the vacuum generating element 231 continues to pump the gas inside the transfer member 221 to the sewage pipe 222 to form a sewage fluid, so that the sewage in the sewage pipe 222 is discharged to the sewer pipe 30 through the sewage fluid.

And (3) an application scene III:

as shown in fig. 7, the cleaning device 10 is a floor scrubber. After the cleaning device 10 is returned to the base station 20, the dirt storage 11 of the cleaning device 10 is plugged into the first dirt collection tube 2231, and the seal 226 forms a seal between the first dirt collection tube 2231 and the cleaning device 10. The vacuum maintaining valve 234 blocks the flow path of the sewage assembly 23 after the vacuum generating element 231 completes the creation of the negative pressure environment, and can maintain the vacuum degree inside the relay member 221. In other words, the base station 20 may previously create a negative pressure environment inside the transfer 221 before the cleaning apparatus 10 returns to the base station 20, so that when the cleaning apparatus 10 returns to the base station 20, the dirt discharge operation can be performed without waiting for the vacuum generating element 231 to create the negative pressure environment, and the vacuum generating element 231 can be selected to be of a lower power type.

Specifically, the first sewage collection control valve 2241 is controlled to block a flow path between the cleaning device 10 and the transit member 221 and the sewage control valve 225 is controlled to block a flow path between the transit member 221 and the sewer pipe 30, the vacuum generating element 231 withdraws the gas inside the transit member 221 through the inflow pipe 232, and the withdrawn gas is discharged to the sewage pipe 222 through the outflow pipe 233 to create a negative pressure environment inside the transit member 221 in advance. After the creation of the negative pressure environment is completed, the vacuum maintaining valve 234 blocks the flow path of the sewage assembly 23 to maintain the vacuum degree inside the relay 221.

After the cleaning device 10 is returned to the base station 20, the drain 12 of the dirt container 11 on the cleaning device 10 is docked with the first dirt collection pipe 2231. After that, the drain port 12 is opened, and the sewage in the sewage storage member 11 is discharged to the first sewage collection pipe 2231 under the self-gravity; then, the first dirty control valve 2241 is controlled to conduct the flow path between the cleaning apparatus 10 and the transfer member 221, and the dirty in the first dirty pipe 2231 is discharged to the transfer member 221 under the action of self gravity and negative pressure; then, the sewage control valve 225 is controlled to conduct the flow path between the transit member 221 and the sewer pipe 30 so that the sewage in the transit member 221 is discharged to the sewage pipe 222; thereafter, the first sewage collection control valve 2241 is maintained to communicate with the flow path between the cleaning device 10 and the intermediate member 221, while the sewage control valve 225 is controlled to block the flow path between the intermediate member 221 and the sewer pipe 30 and the vacuum maintaining valve 234 is controlled to communicate with the flow path of the sewage assembly 23, and the vacuum generating element 231 continues to pump the gas inside the intermediate member 221 to the sewage pipe 222 to form a sewage fluid, so that the sewage in the sewage pipe 222 is discharged to the sewer pipe 30 through the sewage fluid.

And application scene IV:

as shown in fig. 8, the cleaning device 10 is a floor scrubber. After the cleaning device 10 returns to the base station 20, the dirt storage 11 of the cleaning device 10 interfaces with the first dirt collection tube 2231. Thereafter, the drain port 12 is opened, and the sewage in the sewage storage member 11 is discharged to the first sewage collecting pipe 2231 by its own weight. Thereafter, the third dirty control valve 2243 is controlled to conduct the flow path between the cleaning apparatus 10 and the drain pipe 30, and the dirty in the first dirty pipe 2231 is discharged to the drain pipe 222 through the transit member 221; thereafter, the third pollution control valve 2243 is controlled to block the flow path between the cleaning device 10 and the outlet pipe 233, the vacuum generating element 231 draws in the gas of the external environment through the inlet pipe 232 therein, and then the vacuum generating element 231 outputs the drawn-in gas to the drain pipe 222 through the outlet pipe 233 to form a drain fluid, so that the dirty in the drain pipe 222 is discharged to the drain pipe 30 through the drain fluid.

Since the cleaning device 10 is generally located above the base station 20 after the cleaning device 10 returns to the base station 20, the dirt in the dirt storage member 11 can be discharged to the first dirt collecting pipe 2231 under the action of self gravity, while the drain pipe 222 is generally horizontally placed and has a longer length, the height difference between the outlet and the inlet of the drain pipe 222 is not significant, so that the kinetic energy loss of the dirt in the drain pipe 222 is large, the dirt is difficult to be discharged cleanly, and the dirt is easily accumulated and blocked in the drain pipe 222 due to the slow flow rate of the dirt. Accordingly, the vacuum generating element 231 can increase the pressure inside the drain pipe 222 by outputting the drain fluid to discharge the dirt in the drain pipe 222 to the drain pipe 30, so that the dirt can be discharged as much as possible, and the risk of clogging of the pipe assembly 22 and the drain pipe 30 can be reduced.
