Description

Clean basic station and clean system

Technical Field

The invention relates to the technical field of cleaning equipment, in particular to a cleaning base station and a cleaning system.

Background

The cleaning system comprises a cleaning base station and a cleaning device, wherein the cleaning base station is connected with the cleaning device. The cleaning device is used for cleaning the ground, and the cleaning base station is used for providing a water source for the cleaning device and recovering sewage in the cleaning device. In particular, the cleaning station may include a wastewater tank and a negative pressure pump. The negative pressure pump is used for making the sewage bucket in a negative pressure state so as to pump sewage in the sewage tank of the cleaning base station and the sewage tank of the cleaning equipment, so that the sewage flows into the sewage bucket of the cleaning base station.

However, when the sewage in the sewage tank reaches a certain amount, the negative pressure pump pumps the water vapor mixture when the sewage tank is pumped with negative pressure. This results in the water-vapor mixture being discharged from the outlet of the negative pressure pump into the air, so that the sewage in the water-vapor mixture is discharged on the ground, causing ground pollution.

Disclosure of Invention

The invention provides a cleaning base station and a cleaning system, which can prevent a negative pressure pump from discharging sewage on the ground.

In order to achieve the above purpose, the invention adopts the following technical scheme:

in a first aspect, the present invention provides a cleaning base station comprising: the first water tank, the first pump and the multi-way joint.

Wherein the first pump has a first inlet and a first outlet, the first inlet being in communication with the first tank for withdrawing fluid in the first tank, the fluid comprising water. The multi-way joint has a second inlet in communication with the first outlet and a second outlet for communicating with the drain passage to allow water in the fluid to flow into the drain passage.

According to the cleaning base station provided by the invention, one end of the first pump is connected with the first water tank and is used for pumping fluid in the first water tank, so that the first water tank is in a negative pressure state, and the other end of the first pump is connected with the drainage channel through the multi-way joint. Thus, the fluid pumped by the first pump can directly flow into the drainage channel through the multi-way joint, and the ground pollution caused by the fluid pumped by the first pump flowing on the ground is avoided.

In one possible implementation, the multi-way joint further has a third inlet, and the cleaning base station further includes a first communication assembly.

The first end of the first communication component is communicated with the third inlet, the second end of the first communication component is communicated with the first water tank, when the first pump is pumping fluid in the first water tank, the first communication component is in a closed state, and when the first pump is not pumping fluid in the first water tank, the first communication component is in one-way conduction, so that water in the first water tank flows into the multi-way joint.

When the first pump works, the first communication assembly is in a closed state, so that the first water tank can be kept in a closed state, and the first pump can conveniently pump sewage in the first water tank and sewage in the sewage tank of the cleaning equipment. When the first pump is not in operation, the first communication assembly is in one-way conduction, and water in the first water tank can flow into the multi-way joint through the first communication assembly so as to empty the water in the first water tank.

In one possible implementation, the first communication assembly includes a first valve.

The first end of the first valve is communicated with the third inlet, the second end of the first valve is communicated with the first water tank, when the first pump is pumping fluid in the first water tank, the first valve is in a closed state, and when the first pump is not pumping fluid in the first water tank, the first valve is in one-way conduction, so that water in the first water tank flows into the multi-way joint.

That is, the unidirectional conduction of the first communication assembly is due to the unidirectional conduction of the first valve therein.

In one possible implementation, the first valve is a duckbill valve or a floating ball type one-way valve.

In one possible implementation, the cleaning base station further includes a second pump, a first end of the second pump being in communication with the second outlet, and a second end of the second pump being configured to be in communication with the drain channel.

The first end of the second water tank is connected with an external water source, the second end of the second water tank is communicated with the first end of the second communication assembly, the second end of the second communication assembly is communicated with the fourth inlet, and when water in the second water tank flows into the second communication assembly, the second communication assembly is conducted unidirectionally.

When the water quantity in the second water tank reaches a certain quantity, the water can flow into the multi-way joint through the second communication assembly and then is discharged into the drainage channel, so that the water in the second water tank is prevented from overflowing the ground.

In one possible implementation, the second communication assembly includes a second valve.

The first end of the second valve is communicated with the second end of the second water tank, the second end of the second valve is communicated with the fourth inlet, and when water in the second water tank flows into the second valve, the second valve is conducted unidirectionally. That is, the unidirectional communication of the second communication assembly is due to unidirectional communication of the second valve therein.

In one possible implementation, the second valve includes a valve body and a float ball.

The valve body is provided with a containing cavity, and the floating ball is arranged in the containing cavity. The first end of the accommodating cavity is communicated with the second end of the second water tank, the second end is communicated with the fourth inlet, the area of the cross section of the first end of the accommodating cavity is larger than that of the cross section of the second end of the accommodating cavity, and the first end of the accommodating cavity is located above the second end of the accommodating cavity.

In one possible implementation manner, the cleaning base station further includes: a cleaning liquid tank and a third pump. The cleaning liquid tank is communicated with the second water tank through a third pump.

The cleaning liquid tank is used for adding a certain amount of cleaning liquid into the second water tank under the pressure of the third pump so that the cleaning liquid is contained in the water in the second water tank. The second water tank can provide water with cleaning liquid for the cleaning device, so that the cleaning device can clean the floor conveniently.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present disclosure, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements.

The related art cleaning system includes a cleaning base station, and a cleaning device connected to the cleaning base station. The cleaning equipment is a sweeper, the cleaning base station comprises a clean water bucket, a sewage bucket and a negative pressure pump, and the clean water bucket and the sewage bucket are mutually independent. The clean water bucket is used for storing clean water and providing clean water for the cleaning equipment, and the sewage bucket is used for storing sewage of the cleaning equipment and discharging the sewage into the drainage channel. The negative pressure pump is communicated with the sewage bucket and is used for extracting gas in the sewage bucket to enable the inside of the sewage bucket to be in a negative pressure state so as to facilitate the extraction of sewage in the sewage tank of the cleaning base station and the sewage tank of the cleaning equipment in the negative pressure state. However, when the sewage in the sewage tank of the cleaning base station is too full, the negative pressure pump easily pumps the water vapor mixture into the sewage tank when pumping the gas in the sewage tank. I.e. when there is too much sewage in the sewage tank, the negative pressure pump will pump to a mixture comprising sewage, as well as gas. For the gas, it can be discharged directly into the air through the outlet of the negative pressure pump. However, in the case of sewage, the negative pressure pump discharges the sewage on the ground, causing ground pollution.

In view of the above, embodiments of the present invention provide a cleaning system that may include a cleaning base station and a cleaning device to which the cleaning base station is connected.

The connection here may include a mechanical connection or a communication connection.

The cleaning base station in the embodiment of the invention can comprise a sewage bucket and a negative pressure pump, wherein one end of the negative pressure pump is connected with the sewage bucket, and the other end of the negative pressure pump is used for being connected with a drainage channel. Thus, when the negative pressure pump pumps the water-vapor mixture, the water-vapor mixture flows into the drainage channel, so that the sewage is prevented from flowing on the ground to pollute the ground. The following describes in detail the specific structure of the cleaning base station provided in the embodiment of the present invention.

Fig. 1 shows a schematic structural diagram of a cleaning base station provided by an embodiment of the present invention, and fig. 2 shows a schematic structural diagram of a frame of a cleaning base station provided by an embodiment of the present invention.

As shown in fig. 1 and fig. 2, a cleaning base station provided in an embodiment of the present invention may include: a first water tank 11, a first pump 12 and a multi-way connection 13.

Wherein the first pump 12 has a first inlet and a first outlet, the first inlet being in communication with the first tank 11 for withdrawing a fluid in the first tank 11, the fluid comprising water. The multi-way junction 13 has a second inlet 131 and a second outlet 132, the second inlet 131 being in communication with the first outlet, the second outlet 132 being for communication with the drain channel for allowing water in the fluid to flow into the drain channel.

It should be understood that the above-described first tank 11 may be a sewage tank for cleaning a base station.

The first pump 12 may be an air pump (or a negative pressure pump), which may be located at the top of the first water tank 11.

The fluid may be a water vapor mixture including both the sewage in the sewage tank and the gas, and of course, the fluid may include only the sewage. I.e. the water in the fluid may be sewage in the sewage tank.

According to the cleaning base station provided by the embodiment of the invention, one end of the first pump is connected with the first water tank and is used for pumping fluid in the first water tank, so that the first water tank is in a negative pressure state, and the other end of the first pump is connected with the drainage channel through the multi-way joint. Thus, the fluid pumped by the first pump can directly flow into the drainage channel through the multi-way joint, and the ground pollution caused by the fluid pumped by the first pump flowing on the ground is avoided.

Optionally, as shown in fig. 1, the multi-way connector 13 may further have a third inlet 133, and the cleaning base station may further include a first communication component.

The first end of the first communication assembly is communicated with the third inlet 133, the second end is communicated with the first water tank 11, the first communication assembly can be in a closed state when the first pump 12 is pumping the fluid in the first water tank 11, and the first communication assembly is in one-way conduction when the first pump 12 is not pumping the fluid in the first water tank 11, so that the water in the first water tank 11 flows into the multi-way joint 13.

When the first pump 12 pumps the fluid in the first water tank 11, the first water tank 11 needs to be in a sealed state, and thus the first water tank 11 needs to be disconnected from the multi-way joint 13, i.e., the first communication assembly is turned off. When the water in the first water tank 11 needs to be emptied, the first water tank 11 needs to be communicated with the multi-way joint 13, so that the water in the first water tank 11 flows into the multi-way joint 13 along the first communication assembly, and then flows into the drainage channel from the first outlet of the multi-way joint 13. That is, the first communication means is a one-way communication means, allowing only the liquid to flow from the first tank 11 into the multi-way joint 13, but not from the multi-way joint 13 into the first tank 11. And whether the first communication assembly is on unidirectionally, depends on whether the first pump 12 is operating.

It should be appreciated that the first communication assembly may be connected to the bottom end of the sidewall of the first water tank 11 in order to facilitate the water in the first water tank 11 to be discharged into the multi-way joint through the first communication assembly when the first pump 12 is not operated.

Alternatively, as shown in FIG. 2, the first communication assembly may include a first valve 14.

The first valve 14 has a first end in communication with the third inlet 133 and a second end in communication with the first tank 11, and the first valve 14 is placed in a closed state when the first pump 12 is pumping fluid in the first tank 11. When the first pump 12 does not pump the fluid in the first water tank 11, the first valve 14 is unidirectionally conducted, so that the water in the first water tank 11 flows into the multi-way joint 13 and then flows into the drainage channel.

It can be seen that the unidirectional conduction of the first communication assembly is due to unidirectional conduction of the first valve 14, i.e. the first valve 14 is a unidirectional valve.

First valve 14 may be, for example, a duckbill valve or a floating ball check valve.

In one embodiment, the first valve 14 is a duckbill valve.

The duckbill end of the duckbill valve has two lobes that are drawn together when the first pump 12 is in operation, i.e., in a negative pressure state, i.e., the duckbill valve is in an off state. When the first pump 12 is not in operation, i.e. in its natural state, the two lobes are separated, i.e. the duckbill valve is in the on state.

In another embodiment, the first valve 14 is a floating ball check valve.

The floating ball type one-way valve comprises a valve body with a containing cavity and a floating ball, wherein the floating ball is arranged in the containing cavity. The valve body of the first valve may be horizontally disposed, obliquely disposed or vertically disposed between the first water tank 11 and the multi-way joint. The first end of the receiving chamber is connected to the third inlet 133 of the multi-way junction 13 and the second end of the receiving chamber is connected to the first tank 11. The cross-sectional area of the first end of the receiving cavity is greater than the cross-sectional area of the second end of the receiving cavity. And the size of the cross section of the first end of the accommodating cavity is larger than the diameter of the floating ball, and the size of the cross section of the second end of the accommodating cavity is smaller than the diameter of the floating ball. That is, the floating ball can only block the second end of the accommodating cavity, but cannot block the first end of the accommodating cavity, so that the unidirectional conduction of the first valve 14 can be ensured. Meanwhile, in order to prevent the floating ball from leaving the accommodation chamber from the first end of the accommodation chamber, the first end of the accommodation chamber may be provided with a filter screen.

Under the negative pressure state, the floating ball is clung to the second end of the accommodating cavity under the action of negative pressure suction force, so that the first water tank 11 and the multi-way joint 13 are blocked, namely the floating ball type one-way valve is in a closing state. In a natural state, no negative pressure suction exists, so that the floating ball can roll in the accommodating cavity, namely, the floating ball can leave the second end of the accommodating cavity. At this time, since the first end of the accommodating chamber is provided with the filter screen, the floating ball can be prevented from rolling out of the first end of the accommodating chamber to be separated from the accommodating chamber. Based on this, the first water tank 11 and the multi-way joint 13 can be made conductive, i.e., the floating ball type check valve is in a conductive state.

It should be understood that in a natural state, even though the floating ball is closely attached to the end of the accommodating cavity connected to the first water tank 11, since there is no negative pressure suction at this time, once the water in the first water tank 11 flows into the accommodating cavity under the power, the floating ball is pushed away from the second end of the accommodating cavity under the impact of the water.

Optionally, the first communication assembly may further include a first pipe and a second pipe (the first pipe and the second pipe are not shown in fig. 1 and 2).

Illustratively, a first end of the first valve 14 may be in communication with the third inlet 133 of the multi-way junction 13 via a first conduit, and a second end of the first valve 14 may be in communication with the first tank 11 via a second conduit.

It should be noted that the structure of the first valve 14 is not limited thereto, i.e. the first valve may be a one-way valve with other structures, which is not limited in the embodiment of the present invention.

Alternatively, as shown in fig. 1 and 2, in order to facilitate the water discharge in the first water tank 11, a corresponding power needs to be provided. Thus, the above-described cleaning station may further comprise a second pump 15.

The first end of the second pump 15 communicates with the second outlet 132, and the second end is for communicating with the drain passage. That is, the second pump 15 may be located at the first outlet of the multi-way junction 13, and water in the first water tank 11 may be pumped when the second pump 15 is operated.

The second pump 15 is a water pump, and for example, the second pump may be a vane type water pump, that is, a vane type pump. And, the first pump 12 and the second pump 15 are alternately operated.

The reason why the first pump 12 and the second pump 15 need to operate alternately is that: when the first pump 12 is operated, the first water tank 11 needs to be in a closed state, and then the first communication assembly needs to be in an off state. That is, at this time, the first water tank 11 is blocked from the third inlet 133 of the multi-way junction 13, and the water in the first water tank 11 cannot flow into the multi-way junction through the first communication assembly. If the second pump is also operated at this time, the first communication assembly may be caused to be unidirectionally conducted by the impact of the water in the first water tank 11, which may deteriorate the airtight properties of the first water tank 11. Therefore, the first pump 12 and the second pump 15 need to operate alternately.

As regards when the first pump 12 is operated, when it is stopped, it can be related to the amount of sewage in the sewage tank in the first tank 11, and in the sewage tank of the cleaning device. The sump in the first tank 11 and the sump of the cleaning apparatus may be provided with water level sensors for monitoring the water level in the sump in the first tank 11 and the sump of the cleaning apparatus, respectively. When the water level sensor monitors that the water level in the sewage tank of the first water tank 11 or the water level in the sewage tank of the cleaning apparatus reaches a preset guard height, the water level sensor may transmit a water level signal to the controller of the cleaning base station. After receiving the water level signal, the controller converts the water level signal into a first electrical signal for controlling the operation of the first pump 12, i.e., an operation signal of the first pump 12, and transmits the operation signal to the first pump 12. When the first pump 12 receives the operation signal, it is automatically started to pump out the sewage in the sewage tank of the first tank 11 or the sewage tank of the cleaning apparatus.

As regards when the second pump 15 is working, when it is stopped, it can be related to the quantity of water in the first tank 11. Then, a water level sensor may be provided in the first water tank 11 for monitoring the water level in the first water tank 11. When the water level sensor detects that the water level in the first water tank 11 reaches the warning level (i.e., the amount of water stored in the first water tank has reached the maximum amount), the water level sensor may transmit a water level signal to the controller of the cleaning base station. After receiving the water level signal, the controller converts the water level signal into a second electric signal for controlling the operation of the second pump 15, i.e., an operation signal of the second pump 15, and transmits the operation signal to the second pump 15. When the second pump 15 receives the working signal, it is automatically started to pump out the water in the first water tank 11 and enter the drainage channel along the first communication assembly and the multi-way joint.

It is to be understood that the controller of the cleaning base station may be a controller in a broad sense. For example, the controller may be a control chip. The controller may have stored therein control instructions that control the different structures or components in the cleaning base station.

Optionally, as shown in fig. 1 and 2, the multi-way connector 13 further has a fourth inlet 134, and the cleaning base station may further include a second water tank 16 and a second communication assembly (not shown in fig. 1 and 2).

The second tank 16 has a first end connected to an external water source and a second end in communication with a first end of a second communication assembly, which is in communication with the fourth inlet 134. When water in the second water tank 16 flows into the second communicating member, the second communicating member is made to be unidirectionally conductive.

Illustratively, the second tank 16 is a clean water tub for cleaning a base station, and an external water source may be in communication with a first end of the second tank 16 through a valve to provide a water source to the second tank 16. The second end of the second water tank 16 is connected to the multi-way junction 13 by a second communication assembly. I.e. the second water tank 16 is connected to the multi-way connection 13 via a second communication assembly. When the water in the second water tank 16 reaches a certain amount, the water in the second water tank 16 overflows into the second communication assembly, so that the second communication assembly is conducted unidirectionally, and the overflowed water in the second water tank 16 flows into the drainage channel through the multi-way joint 13, and the overflowed water in the second water tank 16 can be prevented from overflowing to the ground. Meanwhile, since the second communication assembly can be conducted only in one direction, it is possible to prevent the fluid in the multi-way joint 13 from entering the second water tank 16 through the second communication assembly, i.e., to prevent the water in the second water tank 16 from being contaminated.

It will be appreciated that the valve between the external water source and the first end of the second tank 16 may be a solenoid valve, the operating state of which may be controlled by the controller of the cleaning base station. Of course, the valve between the external water source and the first end of the second tank 16 may also be a mechanical valve. For example, the mechanical valve may be a faucet.

Optionally, the cleaning base station may further include a pressure reducing valve.

The pressure relief valve may be located before the valve between the external water source and the first end of the second tank 16 for reducing the pressure of the external water source. I.e. the external water source passes through the pressure relief valve before it enters the second tank 16 through the valve between the external water source and the first end of the second tank.

Optionally, in order to implement the automatic water supply and drain function of the cleaning base station, the cleaning base station may further include a water full sensing device (not shown in fig. 1 and 2). The water full sensing means may be provided in the second water tank 16 for monitoring the water level in the second water tank 16.

When the water level in the second water tank 16 is monitored to reach the preset level, the continuous water injection into the second water tank 16 may be stopped, and when the water level in the second water tank 16 is monitored to not reach the preset level, the continuous water injection into the second water tank 16 is continued. Therefore, the location of the water full sensing monitoring device in the second tank 16 is particularly important.

Illustratively, in order to ensure that both an external water source is supplying sufficient water to the second tank 16 and that the water in the second tank 16 does not overflow to the ground, a water fullness sensing device may be provided at the lower side edge of the outlet of the second tank 16. The height of the outlet is a preset height, and the outlet is the connection between the second water tank 16 and the second communication component.

In the normal case of the water full sensing device, the water full sensing device may send the water level signal (i.e., the water level signal) to the controller of the cleaning base station when the water full sensing device monitors that the water level in the second tank 16 reaches the lower edge of the outlet. After receiving the water level signal, the controller converts the water level signal into an electrical signal (i.e., a shut-off signal) that controls the solenoid valve to shut-off, and sends the shut-off signal to the solenoid valve that connects the external water source with the second water tank 16. After receiving the shut-off signal, the solenoid valve automatically shuts off, stopping the external water supply from adding water to the second water tank 16, so that water in the second water tank 16 does not flow into the second communication assembly.

When the water level in the second tank 16 reaches the lower edge of the outlet, the external water source is still filling the second tank 16 when the water level sensing means fails. Once the water level in the second tank 16 reaches the outlet, water in the second tank 16 flows into the second communication assembly and then into the multi-way junction and finally into the drain passage, thereby avoiding that water in the second tank 16 does not overflow to the ground.

Optionally, the second communication assembly may include a second valve.

The first end of the second valve communicates with the second end of the second tank 16, which communicates with the fourth inlet 134, and when water in the second tank 16 flows into the second valve, the second valve is made to conduct unidirectionally. It can be seen that the unidirectional conduction of the second communication component is due to the unidirectional conduction of the second valve, i.e. the second valve is a unidirectional valve.

In one embodiment, the second valve may also include a valve body having a receiving cavity and a float ball disposed within the receiving cavity. The first end of the receiving chamber communicates with the second end of the second tank 16, the second end communicates with the fourth inlet 134, the cross-sectional area of the first end of the receiving chamber is greater than the cross-sectional area of the second end of the receiving chamber, and the first end of the receiving chamber is located above the second end of the receiving chamber.

When the water in the second water tank 16 does not flow into the second valve, the floating ball can be positioned at the second end of the accommodating cavity under the action of gravity to block the fourth inlet 134, so that the space between the multi-way joint 13 and the second water tank 16 is blocked. That is, under the action of gravity, when the water in the second water tank 16 does not flow into the second valve, the second valve is in a closed state, so that the water in the multi-way joint 13 cannot flow into the second water tank 16, and the water in the second water tank 16 is prevented from being polluted.

When the water in the second water tank 16 flows into the second valve, under the condition that the water in the accommodating cavity reaches a certain amount, the floating ball can leave the fourth inlet 134 to float in the water under the action of the buoyancy of the water, so that the blockage between the multi-way joint 13 and the second water tank 16 is relieved, the second water tank 16 is communicated with the multi-way joint, and the water in the second water tank 16 flows into the multi-way joint 13 from the fourth inlet 134. When there is no water in the receiving chamber, the float ball will re-abut against the fourth inlet 134, blocking the multi-way connection 13 from the second tank 16.

It should be noted that the structure of the second valve is not limited thereto, that is, the second valve may be a check valve with other structures, which is not limited in the embodiment of the present invention.

As can be seen from the above, the multi-way junction 13 may have at least four interfaces. For example, when the multi-way joint 13 is a four-way joint, four ports of the four-way joint may be used to connect the first pump 12, the first communication assembly, the second communication assembly, and the second pump, respectively.

However, it should be understood that the connection relationship of the specific interfaces of the multi-way connector 13 is not limited in the embodiment of the present invention.

Optionally, as shown in fig. 1, the cleaning base station provided in the embodiment of the present invention may further include a cover for covering the tank openings of the first water tank 11 and the second water tank 16.

Based on the tank cover, it is possible to prevent contaminants from entering the first water tank 11 from the tank opening of the first water tank 11, and to prevent contaminants from entering the second water tank 16 from the tank opening of the second water tank 16.

In one embodiment, as shown in fig. 1, the tank cover may be a one-piece tank cover, with a first end of the one-piece tank cover connected to the tank opening of the first tank 11 and a second end of the one-piece tank cover connected to the tank opening of the second tank 16. I.e. a cover can cover both the openings of the first tank 11 and the second tank.

In another embodiment, the case cover may include a first case cover and a second case cover, and the first case cover and the second case cover may be connected by a hinge, or the first case cover and the second case cover may be independent from each other. The first tank cover is detachably connected with the tank opening of the first water tank 11 and is only used for covering the tank opening of the first water tank 11. The second tank cover is detachably connected to the tank opening of the second water tank 16 and is only used for covering the tank opening of the second water tank 16. Based on this, the first cover and the second cover may be opened separately or simultaneously.

Optionally, as shown in fig. 2, the cleaning base station may further include: a cleaning liquid tank 18 and a third pump 19. The cleaning liquid tank 18 may be in communication with the second water tank 16 by a third pump 19.

In one embodiment, the cleaning base station may further include a third pipe and a fourth pipe. The third pipe is used to connect the cleaning liquid tank 18 and the third pump 19, and the fourth pipe is used to connect the second water tank 16 and the third pump 19. When the third pump 19 is operated, a certain amount of cleaning liquid can be drawn from the cleaning liquid tank 18 and can be fed into the second water tank 16 along the third and fourth pipes. Thus, the second tank 16 provides water with cleaning fluid to the cleaning apparatus, facilitating cleaning of the floor by the cleaning apparatus.

Optionally, as shown in fig. 2, the cleaning base station may further include: a three-way joint 20, a fourth pump 21, a mop cleaning mechanism 22, a two-position three-way electromagnetic valve 23, a fifth pump 24 and a sewage recycling mechanism 25.

In one embodiment, the inlet of the three-way connection 20 communicates with the second tank 16, and the two outlets of the three-way connection 20 communicate with the fourth pump 21 and the two-position three-way solenoid valve 23, respectively. The fourth pump 21 is also in communication with the mop cleaning mechanism 22 for drawing water from the second tank 16 and injecting it into the mop cleaning mechanism 22. The mop cleaning mechanism 22 is used to wash the mops of the cleaning device.

In another embodiment, the two-position three-way solenoid valve 23 is also in communication with the clean water tank of the cleaning apparatus. The fifth pump 24 connects the second tank 16 with the clean water tank of the cleaning apparatus for pumping water and gas from the clean water tank of the cleaning apparatus to place the clean water tank of the cleaning apparatus in a negative pressure state. When the clean water tank of the cleaning apparatus is in a negative pressure state and the two-position three-way electromagnetic valve 23 is opened, water in the second water tank 16 can be injected into the clean water tank of the cleaning apparatus.

The two-position three-way electromagnetic valve is an electromagnetic valve controlled by double coils. Wherein, the power is turned off after one coil is instantly electrified, so that the electromagnetic valve is opened, and the power is turned off after the other coil is instantly electrified, so that the electromagnetic valve is closed. With this structure, the solenoid valve can be kept in a closed or open state for a long time, which can make the service life of the coil longer.

In another embodiment, the sewage recovery mechanism 25 connects the first water tank 11 with the sewage tank of the cleaning apparatus for recovering sewage in the sewage tank of the cleaning apparatus.

It will be appreciated that the operating conditions of the third pump 19, the fourth pump 21, the two-position three-way solenoid valve 23 and the fifth pump 24 may also be controlled by a controller in the cleaning base station.

Optionally, as shown in fig. 2, the cleaning base station may further include a plurality of water filtering nets for filtering impurities in water to reduce impurities in water entering the next container.

In one embodiment, a first water filter valve is provided between the first water tank 11 and the waste water recovery mechanism 25 for filtering impurities in the waste water in the cleaning apparatus.

In another embodiment, a second water filter valve is provided between the second water tank 16 and the three-way connection 20 for filtering impurities in the second water tank.

Optionally, each of the water filter valves is removable. Therefore, each water filter valve can be detached periodically to be cleaned.

It will be appreciated that the materials from which each part of the cleaning base station is made may be different in order to extend the useful life of the cleaning base station.

For example, the sewage tank may be made of a material having high hardness and toughness. Because particles such as small stones may exist in the sewage tank, in order to prevent the particles from scratching the inner wall of the sewage tank, the material for manufacturing the sewage tank can be made of a material with high hardness and toughness.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
