That is to say: the sewage output channel 30b may be defined only on the base station body, or only on the water tank, or defined on both the water tank and the base station body, or in other manners. No matter sewage received is directly outputted from the cleaning system <NUM> or the second sewage cavity 41b, as long as the sewage generated by the cleaning system <NUM> can be discharged to the outside of the base station.

For details, reference may be made to the above-mentioned descriptions about the clean water input channel 30a. Of course, based on the different functions of the sewage output channel 30b and the clean water input channel 30a, targeted arrangements may be set accordingly.

When the air pressure at the downstream side of the valve body <NUM> is greater than the air pressure at the upstream side of the valve body <NUM>, the valve body <NUM> may change from the first state to a third state, the valve body <NUM> is closed in the third state ( i.e., neither gas passes through nor fluid flows through).

It should be noted that the upstream side of the valve body refers to the side where the sewage flows through first in the direction of the sewage flowing through, and the downstream side of the valve body refers to the side where the sewage flows through later in the direction of the sewage flowing through.

The above-mentioned the first pump and/or the second pump may be connected with a controller (not shown) arranged on the base station body for controlling the pumps operating. In case the first pump and/or the second pump is power driven, the first pump and/or the second pump may also be connected to a power supply module (not shown) in the base station body, so that the power supply module can be used to provide power required for the operation to the pump.

Moreover, the present invention still utilizes the second clean water cavity 41a and the second sewage cavity 41b for temporary storing water while achieving the automatic water feeding and sewage drainage, which effectively guarantees the reliability of water supplying to the base station of the present invention, and is also conducive to improve the convenience for using the base station.

With regards the clean water output channel and the sewage input channel, there are also various implementation measures, as long as they can be communicated with the cleaning system <NUM>. In the embodiments as shown in <FIG>, <FIG> and <FIG>, the clean water output channel includes a clean water interface 42a provided on the water tank, and the cleaning system <NUM> includes a clean water interface 81a provided on the base station body, when the water tank is installed on the base station body, the clean water interfaces 42a and 81a are coupled to realize a communication between the clean water output channel and the cleaning system <NUM>. The sewage input channel includes a sewage interface 42b arranged on the water tank, and the cleaning system <NUM> includes a sewage interface 81b arranged on the base station body, when the water tank is installed on the base station body, the sewage interfaces 42b and 81b are coupled to realize a communication between the sewage input channel with the cleaning system <NUM>. It should be understood that there are different ways for the clean water interfaces 42a and 81a to be coupled, and different ways for the sewage interfaces 42b and 81b to be coupled. Illustratively, the clean water interface 81a on the base station body is penetrated into the second clean water cavity 41a through the clean water interface 42a on the water tank, the sewage interface 81b on the base station body is penetrated into the second sewage cavity 41b through the sewage interface 42b on the water tank. By such a way, clean water will not directly flow through the clean water interface 42a which acts as a clean water output channel on the water tank, and the sewage will not directly flow through the sewage interface 42b which acts as a sewage input channel on the water tank. In addition, the clean water output channel and the sewage input channel may also include structures such as pipes arranged on the water tank, and so on, which is not limited herein.

In addition, in order to make the sewage enter the second sewage cavity 41b from the cleaning system <NUM> smoothly, the water tank may be provided with an gas hole <NUM> communicating with the second sewage cavity 41b and the outside (as shown in <FIG> and <FIG> ).

In some embodiments, a negative pressure pump (not shown) may be provided at the gas hole <NUM> to evacuate the second sewage cavity 41b. In the case the second sewage cavity 41b is in a negative pressure state, the sewage from the cleaning system <NUM> may flow into the second sewage cavity 41b. In order to cooperate with the negative pressure pump to perform the evacuating, the valve body <NUM> (as shown in <FIG>) is provided to the sewage output channel 30b. In a first state, the valve body <NUM> is slightly opened (for example, slightly splayed) to communicate to the outside and restrict the sewage flowing out. When the negative pressure pump performs evacuating, the valve body <NUM> will be closed under the action of the negative pressure pump, such that the second sewage cavity 41b is capable of being evacuated to a negative pressure state. When the pressure from the sewage reaches a certain level, the valve body <NUM> will be opened (e.g., splayed) to discharge the sewage. It should be noted that, during the second sewage cavity 41b is evacuated, in case there is sewage in the channel between the valve body <NUM> and the second sewage cavity 41b, the valve body <NUM> may not be closed and remain communicating to the outside to restrict the sewage flowing out. Alternatively, the valve body <NUM> may not have a closed state. Specifically, when the sewage output channel 30b is provided with the second pump <NUM>, the valve body <NUM> is preferably arranged downstream of the second pump <NUM>.

It should be noted that "slightly opened" means that the valve body <NUM> has a small gap or a small hole. Due to the existence of the small gap or the small hole, the valve body <NUM> is capable of allowing gas to pass through at normal conditions, but cannot allow fluid to flow out. The maximum slit width of the small gap or the maximum aperture of the small hole may be <NUM> millimeter (mm)-<NUM>, and in the embodiment of the present invention, the maximum slit width or the maximum aperture may be <NUM>. Of course, in other embodiments, those skilled in the art may design according to actual needs, as long as the above effects can be achieved.

Preferably, the valve body <NUM> has a slightly opened and retractable channel <NUM> in normal state. When being evacuated, the channel <NUM> can correspondingly contract and then close due to its own retractable characteristics, thereby enables the second sewage cavity 41b to be evacuated to a vacuum or negative pressure state, and, due to the retractable characteristics of the channel <NUM>, when the sewage pressure increases to a certain extent, the channel <NUM> is opened (larger than normal state) to discharge the sewage. The valve body <NUM> is not limited to a duckbill valve, as long as it has a retractable channel.

If the valve body <NUM> is closed (not slightly opened) in normal state, in the case the second pump <NUM> is not turned on, the pipe section between the second pump <NUM> and the valve body <NUM> defines an gas section that no sewage flows into due to the negative pressure. After the second pump <NUM> is turned on, it needs a long time for the pipe section between the second pump <NUM> and the valve body <NUM> to reach a certain water pressure to open the valve body <NUM> to discharge sewage, such that it will result in a delay for discharging sewage. In this embodiment, the valve body <NUM> may communicates the second sewage cavity 41b and the outside (for example, the valve body <NUM> is in a slightly open state in normal state), once there is sewage in the second sewage cavity 41b, the sewage will flow to the valve body <NUM> but not flow out due to the water tension, such that the sewage can flow out directly from the valve body <NUM> after the second pump <NUM> is turned on.

It should be understood that in the first state (normal state), the valve body <NUM> is not limited to be in a slightly open state, as long as it can communicate to the outside and restrict outflow of the sewage. In addition, the valve body <NUM> is not limited to be cooperatively used with the negative pressure pump.

Of course, in the case the second sewage cavity 41b is formed in a special sewage tank or the base station body, structures such as gas holes, valve bodies, and pumps can also be used for carrying out evacuating operations.

Referring to <FIG>, <FIG>, and <FIG> a and <NUM> b, in an exemplary embodiment, the base station body includes a base station bracket <NUM>, the clean water interface 81a and the sewage interface 81b of the cleaning system <NUM> are arranged on the base station bracket <NUM>, and the base station bracket <NUM> is further provided with an interface <NUM> through which the gas hole <NUM> communicates to the outside.

Referring to <FIG>, the water tank of the present invention further includes a first control valve <NUM> which is configured to close or open the clean water input channel 30a according to a water level in the second clean water cavity 41a. As such, the water tank may automatically supply water to the second clean water cavity 41a according to the water level in the second clean water cavity 41a, and in case the water level is too high, water supply channel will be automatically cut off to prevent the water level in the second clean water cavity 41a being too high, or prevent water from overflowing.

In some embodiments, the first control valve <NUM> may be a floating ball valve which is configured to close or open the clean water input channel 30a according to a water level in the second clean water cavity 41a. In the case the water level in the second clean water cavity 41a is low, water may enter the clean water input channel 30a normally, and the floating ball valve will not interfere with the clean water input channel 30a. As the water level rises, the floating ball valve moves due to the buoyancy of the water, and when the water level in the second clean water cavity 41a reaches a certain height, the floating ball valve blocks the clean water input channel 30a. At this time, the clean water in the clean water input channel 30a can no longer enter the second clean water cavity 41a, so as to prevent the water level being too high. In some embodiments, a valve body structure <NUM> is fixed at the outlet end of the clean water input channel 30a, the floating ball valve includes a floating ball <NUM> and a valve core structure <NUM>, a connecting member <NUM> is connected between the floating ball <NUM> and the valve core structure <NUM>, and a point of the connecting member <NUM> between the floating ball <NUM> and the valve core structure <NUM> is hinged to the valve body structure <NUM> or hinged to other structures. When the water level rises or falls, the float ball <NUM> floats up or down, causing the entire floating ball valve <NUM> to rotate up and down around the hinged point, and when the water level reaches a certain height, the rising of the float ball <NUM> causes the valve core structure <NUM> downwards to block the passage of the valve body structure <NUM>, so as to close the clean water input channel 30a.

In other embodiments, the floating ball valve may be replaced by other devices. Illustratively, other liquid level detecting devices (not shown in the Figure) are provided in the second clean water cavity 41a, the first control valve is electrically connected to the liquid level detecting device, and the first control valve is configured for closing or opening the clean water input channel according to the water level detected by the liquid level detecting device in the clean water cavity. In particular, the liquid level detecting device may include, but is not limited to, at least one of the following: a photoelectric liquid level detecting device, a capacitive liquid level detecting device, a static pressure liquid level detecting device, and the like.

In some embodiments, the clean water input channel 30a may be provided with a first pump (first), and the first pump is configured to provide a power for the second clean water cavity 41a to receive clean water from external waterway. The arrangement of the first pump facilitates the smooth input of clean water to the second clean water cavity 41a through the clean water input channel 30a of the water tank. The sewage output channel 30b may be provided with a second pump <NUM>, and the second pump <NUM> is configured to provide a power for sewage being discharged from the second sewage cavity 41b. The arrangement of the second pump <NUM> is beneficial to smooth sewage discharge from the second sewage cavity 41b to the outside of the base station through the sewage output channel 30b of the water tank.

In an exemplary embodiment, the sewage output channel 30b is provided with the second pump <NUM>, while the clean water input channel 30a is not provided with a pump.

Referring to <FIG> and <FIG>, in some embodiments, the water tank includes a water tank body <NUM> (i.e., the second water tank <NUM>) and an adapter <NUM> detachably connected to the water tank body <NUM>, the water tank receives clean water delivered from the outside of the base station and discharges sewage to the outside of the base station through the adapter <NUM>. The second clean water cavity 41a, the second sewage cavity 41b, the clean water output channel, and the sewage input channel are arranged on the water tank body <NUM>, and the clean water input channel 30a and the sewage output channel 30b are defined in the water tank body <NUM> and the adapter <NUM> (that is, the clean water input channel 30a includes a third clean water channel 3a defined in the water tank body <NUM> and a channel defined in the adapter <NUM>, the sewage output channel 30b includes a third sewage channel 3b defined in the water tank body <NUM> and a channel defined in the adapter <NUM>. In the case the water tank only includes the water tank body <NUM>, the clean water input channel 30a is the third clean water channel 3a and the sewage output channel 30b is the third sewage channel 3b). By the arrangement of the adapter <NUM>, it is convenient for the clean water input channel 30a to be connected to the external waterway and for the sewage output channel 30b to discharge sewage to the outside of the base station. It should be noted that the connection of the water tank to the external water source through the adapter <NUM> is only an optional manner, and the water tank may also not include the adapter <NUM>. In addition, it is not excluded that the base station body is provided with an extension section of the clean water input channel 30a and an extension section of the sewage output channel 30b. When the water tank is installed on the base station body, the clean water input channel 30a and the sewage output channel 30b of the water tank are connected to corresponding extension sections to receive clean water from outside the base station and discharge sewage to the outside of the base station.

In particular, the adapter <NUM> includes a main body <NUM>, a clean water adapting pipe <NUM> which serves as a part of the clean water input channel 30a, and a sewage adapting pipe <NUM> which serves as a part of the sewage output channel 30b. The clean water adapting pipe <NUM> is connected to the part of the clean water input channel 30a located in the water tank body <NUM> through a clean water connecting pipe L, and the sewage adapting pipe <NUM> is connected to the part of the sewage output channel 30b located in the water tank body <NUM> through a sewage connecting pipe M. A check valve <NUM> is provided at one end of the clean water adapting pipe <NUM> connected with the clean water connecting pipe L, the check valve <NUM> is configured to be in a closed state at normal conditions, and is pushed to convert to an open state when the clean water connecting pipe L is inserted into the clean water adapting pipe <NUM>. By the arrangement of the clean water connecting pipe L and the sewage connecting pipe M, it is convenient to install the water tank body <NUM> on the base station body. After the water tank body <NUM> is installed, the clean water connecting pipe L and the sewage connecting pipe M are arranged to connect the adapter <NUM>; in addition, by means of the check valve <NUM> provided in the clean water adapting pipe <NUM> of the adapter <NUM>, clean water in the clean water adapting pipe <NUM> can be prevented from flowing out when the adapter <NUM> is separated from the clean water connecting pipe L.

In this embodiment, the valve body <NUM> is provided in the sewage adapting pipe <NUM>, so that it is unnecessary to set it on the water tank body <NUM>, which is beneficial to the structural layout of the water tank body.

Referring to <FIG> and <FIG>, in some embodiments, the water tank includes a first tank body <NUM> and a second tank body <NUM> which can be separated from each other; the second clean water cavity 41a, the second sewage cavity 41b, the clean water output channel, and the sewage input channel are arranged in the first tank body <NUM>. The clean water input channel 30a includes a first interface 31a arranged on the first tank body <NUM>, a clean water input pipeline 33a and a second interface 32a which are arranged in the second tank body <NUM>.

The sewage output channel 30b includes a third interface 31b arranged in the first tank body <NUM>, a sewage output pipeline 33b and a fourth interface 32b arranged in the second tank body <NUM>. The third interface 31b is communicated with the second sewage cavity 41b, and the fourth interface 32b is arranged at the inlet end of the sewage output pipeline 33b. When the first tank body <NUM> is docked with the second tank body <NUM>, the first interface 31a is coupled with the second interface 32a, and the third interface 31b is coupled with the fourth interface 32b. By virtue of the separable design of the first tank body <NUM> and the second tank body <NUM>, it is convenient to arrange the main structures such as the composition pipes of the clean water input channel 30a and the sewage output channel 30b on the second tank body <NUM>, as well as convenient to take out the first tank body <NUM> which defines the second clean water cavity 41a and the second sewage cavity 41b for cleaning, while the second tank body <NUM> does not need to be taken out to maintain the connection with relevant waterway structures, avoiding re-establishing a connection with the relevant waterway structures every time the water tank is taken out, which is conducive to providing users a better use experience. Of course, the above-mentioned split-type water tank is only an optional manner, and the water tank is not limited to the above-mentioned split-type design.

Referring to <FIG>, <FIG>, and <FIG>, in particular, the first interface 31a may include a first check valve structure 310a, the second interface 32a may include a second check valve structure 320a, the first check valve structure 310a and the second check valve structure 320a are configured to: when the first tank body <NUM> is docked to the second tank body <NUM>, the first check valve structure 310a and the second check valve structure 320a are coupled and pushed with each other to an open state, and when the first tank body <NUM> is separated from the second tank body <NUM>, the first check valve structure 310a and the second check valve structure 320a are automatically reset to a closed state. The third interface 31b may include a third check valve structure <NUM>, when the first tank body <NUM> is docked to the second tank body <NUM>, the third check valve structure 310b and the fourth interface 32b are coupled and the third check valve structure 310b is pushed to an open state, when the first tank body <NUM> is separated from the second tank body <NUM>, the third check valve structure 310b automatically resets to a closed state. By virtue of the two-way check valve arranged between the first interface 31a and the second interface 32a, it can basically avoid outflow of the clean water when the first tank body <NUM> and the second tank body <NUM> are separated; by virtue of the third check valve structure 310b, it can basically prevent outflow of sewage when the first tank body <NUM> and the second tank body <NUM> are separated.

Further, the fourth interface 32b may include a fourth check valve structure 320b, and the third check valve structure <NUM> and the fourth check valve structure 320b are configured to: when the first tank body <NUM> is docked to the second tank body <NUM>, the third check valve structure <NUM> and the fourth check valve structure 320b are coupled and pushed with each other to an open state, and when the first tank body <NUM> and the second tank body <NUM> are separated, the third check valve structure <NUM> and the fourth check valve structure 320b automatically reset to a closed state.

In an exemplary embodiment, the first check valve structure 310a includes a valve body <NUM>, a valve core <NUM>, and an elastic member <NUM>. The valve core <NUM> is movably passed through the valve body <NUM>, and the elastic member <NUM> is disposed between the valve body <NUM> and the valve core <NUM>.

When there is no external force, the valve core <NUM> blocks the passage in the valve body <NUM>, and the valve core <NUM> blocks the passage in the valve body <NUM>; when the first tank body <NUM> is docked to the second tank body <NUM>, the valve core <NUM> and the valve core <NUM> pushes with each other to open the passages in the two valve bodies <NUM> and <NUM>, thereby realizing a communication between the clean water input channel 30a and the second clean water cavity 41a; at the same time, the two elastic members <NUM> and <NUM> are compressed by the movement of the valve cores <NUM> and <NUM> to store elastic potential energy; when the first tank body <NUM> and the second tank body <NUM> are separated, the elastic members <NUM> and <NUM> cause the two valve cores <NUM> and <NUM> to automatically reset to close the passages in the valve bodies <NUM> and <NUM>, which facilitates the clean water to flow out.

With regards the specific designs of the third check valve structure <NUM> and the fourth check valve structure 320b, reference may be made to the above description of the first check valve structure 310a and the second check valve structure 320a, which will not be repeated here.
