[0095] First embodiment

[0096] like Figures 1 to 17 A base station according to a first embodiment of the present invention is shown.

[0097] like Figures 1 to 4 As shown, the base station includes a base station base 1 and a cleaning tank 2. The cleaning tank 2 is arranged above the base station base 1. The cleaning tank 2 is provided with a liquid inlet structure, a liquid discharge structure, and a protrusion 21. The protrusion 21 is used to scrape and decontaminate the mopping and wiping parts of the cleaning robot. A sewage collection chamber is formed between the base station base 1 and the cleaning tank 2, and the liquid discharge structure is connected to the sewage collection chamber. Among them, the liquid inlet structure is used to provide cleaning water to the cleaning tank 2, and the liquid discharge structure is used to discharge the cleaning water in the cleaning tank 2 from the cleaning tank 2, for example, to discharge the cleaning water after cleaning the mopping and wiping parts of the cleaning robot from the cleaning tank 2. The protrusion 21 is a protrusion structure protruding from the bottom of the cleaning tank 2. The protrusion 21 scrapes and decontaminates the mopping and wiping parts of the cleaning robot. Specifically, after the protrusion 21 contacts the mopping and wiping parts, the protrusion 21 and the mopping and wiping parts generate relative motion, so that the protrusion 21 can scrape the stains and garbage on the mopping and wiping parts, and scrape these stains and garbage away from the mopping and wiping parts, so as to achieve the decontamination operation of the mopping and wiping parts. The relative movement between the protrusion 21 and the wiping member may be, for example, that the protrusion 21 is stationary and the cleaning robot rotates the wiping member, so that the wiping member rotates relative to the protrusion 21 .

[0098] In the embodiment of the present invention, the protrusion 21 may be a convex block structure, such as a polygonal column structure, a cylindrical structure, etc. The protrusion 21 may also be a strip structure, such as Figure 1 and Figure 2 As shown, the raised portion 21 is a rib-like structure, which can be called a cleaning rib. There are many ways to arrange the cleaning ribs on the cleaning tank 2, such as an array layout, in which multiple cleaning ribs are arranged in parallel on the cleaning tank 2; or a radial layout, in which multiple cleaning ribs are radially arranged on the cleaning tank 2.

[0099] In the first embodiment, the cleaning tank 2 and the base station base 1 are detachably connected.

[0100] like Figures 4 to 6As shown, the drainage structure includes a filter hole 24, which is arranged at the bottom of the cleaning tank 2, preferably, at the lowest position of the cleaning tank 2. The filter hole 24 is communicated with the sewage collection chamber.

[0101] The liquid inlet structure includes a water spray port. For example, the water spray port is an opening structure arranged on the side wall of the cleaning tank 2, and the cleaning water is sprayed into the cleaning tank 2 through the water spray port.

[0102] In an embodiment of the present invention, cleaning water flows from the cleaning tank 2 to the sewage collection chamber through the filter holes 24. The sewage collection chamber is a cavity structure formed by part of the surface of the base station base 1 and part of the surface of the cleaning tank 2. The sewage collection chamber can be located below the cleaning tank 2. The sewage collection chamber is used to collect cleaning water flowing in from the drainage structure, especially dirty cleaning water after cleaning the mopping parts of the cleaning robot.

[0103] Optionally, the liquid inlet structure includes a water spray port 25 and a liquid inlet component 26. The liquid inlet component 26 is disposed on the cleaning tank 2, and the water spray port 25 is disposed on the liquid inlet component 26, for example, on the top surface of the liquid inlet component 26. When cleaning the mop, the protrusion 21 contacts the mop, and there is a gap between the liquid inlet component 26 and the mop. When cleaning the mop, the mop will not block the water spray port 25 on the liquid inlet component 26, so that water can be sprayed normally. Figure 3 As shown, the liquid inlet component 26 may be a rib-shaped structure.

[0104] like Figure 3 and Figure 6 As shown, the base station also includes a water spray pipe 4 and a water suction pipe 5, which are arranged in the sewage collection chamber, the outlet of the water spray pipe 4 is connected to the water spray port 25, and the inlet of the water suction pipe 5 is connected to the sewage collection chamber, the water spray pipe 4 is used to provide cleaning water to the water spray port 25, and the water suction pipe 5 is used to pump the sewage from the sewage collection chamber. The sewage in the sewage collection chamber is dirty cleaning water from the cleaning tank 2. The cleaning water becomes dirty after cleaning the mopping parts in the cleaning tank 2. The dirty cleaning water flows from the cleaning tank 2 to the sewage collection chamber, and then the water suction pipe 5 pumps the dirty cleaning water in the sewage collection chamber out of the sewage collection chamber, for example, into a sewage tank arranged on the base station for temporary storage.

[0105] Preferably, if Figure 6 As shown, the water suction pipe 5 and the water spray pipe 4 are fixed on the base station base 1 through the buckle 20. The installation through the buckle 20 is simple and convenient.

[0106] In one example, if Figure 6As shown, the buckle 20 is fixed or integrally formed on the water spray pipe 4 and the water suction pipe 5, and a clamping position 17 is provided at a corresponding position of the base station base 1. The buckle 20 is clamped into the corresponding clamping position 17 to fix the water spray pipe 4 and the water suction pipe 5 to the base station base 1.

[0107] The filtering holes 24 on the cleaning tank 2 are used to filter large particles of garbage left when cleaning the mop and wipe parts, so as to prevent the large particles of garbage from clogging the water suction pipe 5 on the base station base 1. In addition, large particles of garbage can be left on the cleaning tank 2, which is convenient for the user to clean the cleaning tank 2 after taking it out.

[0108] In addition, if Figure 4 and Figure 5 As shown, a wall filter water inlet 27 connected to the sewage collection chamber is provided on the wall of the cleaning tank 2. In the vertical direction, the water inlet of the wall filter water inlet 27 is higher than the water inlet of the filter hole 24, and the length of the water inlet of the wall filter water inlet 27 projected in the vertical direction is greater than 0. In this way, the water inlet of the wall filter water inlet 27 has a certain extension length in the vertical direction, and the position of the water inlet of the wall filter water inlet 27 is higher than the position of the water inlet of the filter hole 24, so that the wall filter water inlet 27 is less likely to be blocked by garbage than the filter hole 24. If the garbage cleaned from the mopping part blocks the filter hole 24, the cleaning water on the cleaning tank 2 can also flow from the wall filter water inlet 27 to the sewage collection chamber, thereby avoiding the overflow of the cleaning water from the cleaning tank 2.

[0109] In this embodiment, the wall surface of the cleaning tank 2 is a surface that stands up relative to the bottom of the cleaning tank 2, and can be a side wall of the cleaning tank 2, or a wall surface that stands up in the cleaning tank 2. Among them, the side wall of the cleaning tank 2 is a surface that is arranged around the cleaning tank 2. In this way, the wall surface filtering water flow port 27 can be arranged on the side wall of the cleaning tank 2, or on the wall surface in the middle of the cleaning tank, etc.

[0110] Preferably, the filter holes 24 penetrate the bottom of the cleaning tank 2 in the vertical direction, and the wall filter water outlet 27 penetrates the wall of the cleaning tank 2 in the horizontal direction. The advantage of this is that after the cleaning robot cleans on the base station, garbage and sewage will be left behind. Since the filter holes 24 penetrate the bottom of the cleaning tank 2 in the vertical direction, the garbage will also fall vertically, so these vertical filter holes 24 are very easy to be blocked, and the wall filter water outlet 27 penetrates the wall of the cleaning tank 2 in the horizontal direction, and the garbage falling on the cleaning tank 2 is not easy to block the wall filter water outlet 27. In this way, even if the filter holes 24 are blocked, the sewage can flow into the sewage collection chamber through the wall filter water outlet 27.

[0111] In some examples, such as Figure 4As shown, a magnet 3 can also be installed on the cleaning tank 2, and a magnetic sensor (not shown in the figure) can be installed on the base station base 1. By sensing the magnet 3 with the magnetic sensor, it can be identified whether the cleaning tank 2 is installed on the base station base 1. Preferably, the magnetic sensor is buried inside the base station base 1, so that the magnetic sensor can be isolated from the water inside the base station base 1, which plays a waterproof role.

[0112] like Figure 4 and Figure 5 As shown, a guide structure is also provided in the middle of the cleaning tank 2, and the top surface of the guide structure is a plane slope 231. The function of the plane slope 231 is to allow the universal wheels of the cleaning robot to move along the plane slope 231 when the cleaning robot enters the base station, so as to avoid the universal wheels getting stuck in the cleaning tank 2, thereby causing the cleaning robot to be unable to exit the base station. At the same time, a recess 232 is provided at the rear end of the plane slope 231, so that when the cleaning robot reaches the cleaning position of the base station, the universal wheels enter the recessed position and are suspended, so that the gravity of the front part of the cleaning robot presses the mopping member onto the protrusion 21, thereby ensuring the pressure when cleaning the mopping member and increasing the friction of the protrusion on the mopping member.

[0113] The guide structure further comprises a wall surface, and the wall surfaces arranged on both sides of the plane slope 231 are used to support the plane slope 231. The wall surface filtering water flow port 27 can be arranged on the wall surface of the guide structure.

[0114] It should be understood that in some embodiments, the drainage structure includes a wall filter water outlet 27, which is disposed on the wall of the cleaning tank 2, and the length of the water inlet of the wall filter water outlet 27 projected in the vertical direction is greater than 0. At this time, the bottom of the cleaning tank 2 may not be provided with a filter hole 24, or a filter hole 24 may be provided. Because the wall filter water outlet 27 is connected to the sewage collection chamber formed between the base station base 1 and the cleaning tank 2, the cleaning water on the cleaning tank 2 can flow from the cleaning tank 2 to the sewage collection chamber through the wall filter water outlet 27.

[0115] like Figure 7 and Figure 8As shown, the cleaning tank 2 is clearance-matched with the base station base 1 so that the cleaning tank 2 can be detached from the base station base 1. A first limiting structure is provided on the outer surface of the side wall of the cleaning tank 2, and a second limiting structure is provided on the inner surface of the side wall of the base station base 1. The first limiting structure and the second limiting structure are mutually limited to limit the movement of the cleaning tank 2 in the horizontal direction. For example, the first limiting structure and the second limiting structure are both protrusions, or the first limiting structure and the second limiting structure are one of a protrusion and a groove, etc. When the cleaning tank 2 is installed on the base station base 1, the first limiting structure and the second limiting structure abut against each other, thereby limiting the movement of the cleaning tank 2 in the horizontal direction. In this embodiment, the first limiting structure is the outer surface S1 of the side wall of the cleaning tank 2, and the second limiting structure is the inner surface S2 of the side wall of the base station base 1. In this way, the outer surface S1 of the side wall of the cleaning tank 2 is positioned and matched with the inner surface S2 of the side wall of the base station base 1 to limit the movement of the cleaning tank 2 in the horizontal direction. The base station base 1 or the cleaning tank 2 is provided with a support member 29 that is supported between the base station base 1 and the cleaning tank 2 and is used to limit the downward movement of the cleaning tank 2 (see the third embodiment below for the support member 29). In this way, the horizontal and downward displacement of the cleaning tank 2 is limited. Since the robot will stop on the cleaning tank 2 to clean the mopping parts, there is no need to limit the upward displacement of the cleaning tank 2. Since the installation method of the cleaning tank 2 and the base station base 1 is realized by clearance fit (contour positioning), it is not a tight fit installation method, which is equivalent to putting a horizontal and downward limited and non-tight fit part in a concave groove. Therefore, it is only necessary to lift up on the handle 23 to remove the cleaning tank 2 from the base station base 1, which greatly facilitates the user to disassemble the cleaning tank 2, and the user does not need to put his hand into the contaminated cleaning tank 2. Moreover, the cleaning tank 2 and the base station base 1 are matched with each other in the upper and lower clearances, and there is enough space between the cleaning tank 2 and the base station base 1, so that the tension of water is prevented from adhering to the cleaning tank 2 and the base station base 1 at the same time, so that some overflow prevention accidental touch phenomena can be avoided.

[0116] like Figure 7 As shown, preferably, the outer surface S1 of the side wall of the cleaning tank 2 has the same outer contour as the inner surface S2 of the side wall of the base station base 1, and the size of the outer surface S1 of the side wall of the cleaning tank 2 is a proportional reduction of the size of the inner surface S2 of the side wall of the base station base 1.

[0117] In the embodiment of the present invention, the cleaning tank 2 and the base station base 1 are detachably connected and positioned and installed through a limiting structure (such as a contour surface), and other complex installation forms such as screws do not need to be used, which facilitates the user to disassemble the cleaning tank 2.

[0118] Figure 7 1 is a schematic diagram of disassembling the cleaning tank 2 and the base station base 1. When the cleaning tank 2 is clogged with too much dirt, the cleaning tank 2 can be taken out for cleaning.

[0119] Figure 8 It is a schematic diagram of the installation of the cleaning tank 2 and the base station base 1. When the cleaning tank 2 is cleaned, it only needs to be placed in the corresponding position of the base station, which is convenient and simple to operate.

[0120] like Figure 3 , Figures 9 to 13 As shown, the base station also includes an anti-overflow device for preventing water from overflowing the base station. The anti-overflow device includes a control device and at least one anti-overflow touch piece 6. The anti-overflow touch piece 6 is electrically connected to the control device. When the water level in the base station rises to the height of the anti-overflow touch piece 6 and contacts the anti-overflow touch piece 6, the control device sends out an alarm and / or controls the base station to stop supplying water to the liquid inlet structure.

[0121] Among them, there are many ways to implement the anti-overflow touch sheet, such as a conductive sheet, a pressure detection touch sheet, a water level detection touch sheet, an ultrasonic water level sensor, a photoelectric water level sensor, etc., and the embodiments of the present invention do not specifically limit this.

[0122] The anti-overflow touch sheet 6 can be arranged in a variety of ways. For example, the anti-overflow touch sheet 6 can be arranged on the base station base 1, or the anti-overflow touch sheet 6 can be arranged on the cleaning tank 2, and so on.

[0123] In a specific implementation, the anti-overflow touch piece 6 is arranged in the sewage collection chamber, for example, the anti-overflow touch piece 6 is arranged on the side wall of the base station base 1 in the sewage collection chamber or on the wall of the cleaning tank 2 facing the sewage collection chamber. In the vertical direction, the anti-overflow touch piece 6 is located below the overflow water level Level2 of the base station base 1 and above the lowest point of the water level of the base station base 1.

[0124] Alternatively, if Figure 4 and Fig.13 As shown, an anti-overflow water inlet 28 is provided on the cleaning tank 2, and the position of the anti-overflow water inlet 28 is lower than the overflow water level Level1 of the cleaning tank 2. The anti-overflow touch sheet 6 is provided on the inner surface of the side wall of the base station base 1, and the anti-overflow water inlet 28 is arranged opposite to the anti-overflow touch sheet 6. The opposite arrangement means that the opening of the anti-overflow water inlet 28 faces the anti-overflow touch sheet 6. When the cleaning water flows from the cleaning tank 2 to the sewage collection chamber through the anti-overflow water inlet 28, the cleaning water contacts the anti-overflow touch sheet 6, thereby triggering the anti-overflow operation.

[0125] Fig. 9 It is a cross-sectional view of the base station base 1, and it can be seen that the bottom center of the base station base 1 is the lowest point of the water level of the base station base 1, and the triggering position of the anti-overflow contact piece 6 is lower than the overflow water level Level 2 of the base station base 1. In this way, the water will contact the anti-overflow contact piece 6 before overflowing the base station base 1, thereby triggering an alarm.

[0126] In some examples, one or more anti-overflow contact sheets 6 may be provided on only one side of the base station base 1 .

[0127] In some examples, one or more anti-overflow contact sheets 6 may be provided on both sides of the base station base 1. Figure 3 , Fig. 9 and Fig.13 In the example shown, two anti-overflow contact sheets 6 are respectively provided on both sides of the base station base 1 .

[0128] Fig.10 and Fig.11 It can be seen that the lowest water level points of the cleaning tank 2 and the base station base 1 are both at the center of their bottoms, that is, the water after cleaning will flow to the middle, the water on the cleaning tank 2 will flow into the base station base 1 through the filter holes 24, and the water on the base station base 1 will flow to the middle position and then be pumped away through the suction pipe 5. When the base station base 1 cannot pump water and the water level starts to rise, as long as the water contacts the anti-overflow contact piece 6, the anti-overflow contact piece 6 will produce a voltage change. If the changed voltage value or the change in the voltage value exceeds a preset threshold (the preset threshold can be set in advance on the base station), the anti-overflow system will trigger an alarm and control the base station system to stop working, and the base station will no longer spray or absorb water.

[0129] from Fig.12 It can be seen that the bottom of the anti-overflow water outlet 28 of the cleaning tank 2 is lower than the overflow water level Level1 of the cleaning tank 2. In this way, when the cleaning tank 2 is blocked, water will flow into the sewage collection chamber from the anti-overflow water outlet 28, and will not overflow the cleaning tank 2.

[0130] like Fig.13 As shown, when the filter hole 24 on the cleaning tank 2 is blocked, the water in the cleaning tank 2 will flow out from the anti-overflow water outlet 28. In the process of the water flowing into the sewage collection chamber from the anti-overflow water outlet 28, it will flow through the anti-overflow touch piece 6. When the anti-overflow touch piece 6 contacts the water flow, the anti-overflow touch piece 6 measures the changed voltage value or the changed voltage value exceeds the preset threshold value, the anti-overflow system will sound an alarm and stop the water supply of the base station, for example, the water spray pipe 4 stops supplying water to the cleaning tank 2.

[0131] For example, taking the anti-overflow touch piece 6 as a conductive piece, two anti-overflow touch pieces 6 are arranged on the left and right sides of the inner surface of the side wall of the base station base 1, wherein one of the two anti-overflow touch pieces 6 on the side wall on the same side is a positive conductive piece and the other is a negative conductive piece. Each anti-overflow touch piece 6 is arranged opposite to the anti-overflow water outlet 28. In this way, when the water suction pipe 5 of the base station base cannot pump water, or the water supply of the base station is large, etc., causing the water level in the sewage collection chamber to rise until it overflows one of the positive conductive pieces and one of the negative conductive pieces, the positive conductive piece and the negative conductive piece are turned on to generate an electrical signal, so that the control device issues an alarm and / or controls the base station to stop supplying water to the liquid inlet structure. Alternatively, when the filter holes on the cleaning tank 2 are blocked, if the base station still provides cleaning water to the cleaning tank 2, the cleaning water on the cleaning tank 2 flows to the sewage collection chamber through the anti-overflow water outlet 28 provided on the cleaning tank 2. When the cleaning water flows to the sewage collection chamber through the anti-overflow water outlet 28, since the anti-overflow contact piece 6 is arranged opposite to the anti-overflow water outlet 28, the cleaning water contacts the anti-overflow contact piece 6. If any positive conductive sheet and any negative conductive sheet on the base station base 1 contact the connected cleaning water at the same time, the positive conductive sheet and the negative conductive sheet are turned on to generate an electrical signal, so that the control device issues an alarm and / or controls the base station to stop supplying water to the liquid inlet structure. Specifically, a guide structure is further provided in the middle of the cleaning tank 2, and the top surface of the guide structure is a plane slope 231. A group of filter holes are respectively provided on the left and right sides of the guide structure and at the bottom of the cleaning tank 2. If the filter holes on one side of the cleaning tank 2 are blocked by garbage, the cleaning water on that side of the cleaning tank 2 flows from the anti-overflow water outlet 28 on that side of the cleaning tank 2 to the sewage collection chamber. If the positive conductive sheet and the negative conductive sheet on that side are conducted by the cleaning water, the anti-overflow system performs an anti-overflow operation.

[0132] In another specific implementation, the anti-overflow touch sheet 6 is disposed on the inner surface of the side wall of the cleaning tank 2. In the vertical direction, the anti-overflow touch sheet 6 is located below the overflow water level Level 1 of the cleaning tank 2 and above the lowest point of the tank body 22 of the cleaning tank 2. The overflow water level Level 1 of the cleaning tank 2 is the same as the overflow water level Level 2 of the base station base 1.

[0133] At this time, when the base station base 1 fails to pump water and the water level starts to rise, water flows from the sewage collection chamber through the filter holes to the cleaning tank 2 until the water contacts the overflow prevention touch piece 6, triggering the overflow prevention operation. Since the overflow prevention touch piece 6 is located below the overflow water level Level 1 of the cleaning tank 2, water can be prevented from overflowing from the cleaning tank 2.

[0134] In the embodiment of the present invention, the bottom of the cleaning tank 2 can be parallel to or inclined to the horizontal plane, and the embodiment of the present invention does not specifically limit this. For example, in a specific example, the cleaning tank 2 is tilted relative to the base station base 1. At this time, the bottom of the cleaning tank 2, the top surface of the guide structure, and the top surface of the protrusion arranged thereon are tilted relative to the horizontal plane, so that it is convenient for the cleaning robot to enter the cleaning tank 2 from the lower end of the cleaning tank 2, and the bottom surface of the higher end of the cleaning tank 2 and the base station base 1 are spaced relatively large, so that the space volume of the sewage collection chamber near the higher end of the cleaning tank 2 is larger, so that the volume of the sewage collection chamber is increased, which is conducive to the collection of sewage, and more components are arranged therein, for example, a water spray pipe 4 and a water suction pipe 5 are arranged in the space near the higher end of the cleaning tank 2 of the sewage collection chamber. In addition, the cleaning tank 2 is tilted relative to the base station base 1, which helps the driving wheels arranged on the bottom of the cleaning robot to press on the surface of the base station when the cleaning robot is docked on the base station.

[0135] like Figures 14 to 16 As shown, the base station also includes a drying device, which is used to dry the wiping member 101 and / or the sewage collection chamber of the cleaning robot 10 .

[0136] Optionally, the drying device includes a fan 7 disposed outside the base station base 1, and a duct 16 is disposed inside the base station base 1. The air inlet of the duct 16 is connected to the fan 7, and the air outlet of the duct 16 is connected to the sewage collection chamber. Specifically, the air inlet of the duct 16 is connected to the fan 7 through a ventilation plate 8, the fan 7 is mounted on the upper end of the ventilation plate 8, and the lower end of the ventilation plate 8 is mounted on the base station base 1. The interior of the ventilation plate 8 has a flow channel 81 connecting the duct 16 and the fan 7, and the air outlet of the duct 16 is connected to the sewage collection chamber. A part of the wind generated by the fan 7 is blown toward the wiping part 101 of the cleaning robot 10 through the duct 16 and the filter hole 24, and the wind generated by the fan 7 will also circulate in the sewage collection chamber.

[0137] Since the cleaning robot 10 performs self-cleaning work on the base station, there is moisture inside the mop 101, and the mop 101 is wet. For example, when the cleaning robot 10 has finished its work outside and returns to the base station for the last self-cleaning and charging, the mop 101 of the cleaning robot 10 docked on the base station will be wet. If it is in a space with poor air circulation for a long time, the mop 101 will easily become black and smelly, which will greatly affect the user experience. This base station has added a drying device, such as Fig.16As shown, the wind from the fan 7 passes through the air duct 16 and enters the space between the cleaning tank 2 and the chassis of the cleaning robot 10. For example, a part of the wind passes through the filter holes 24 of the cleaning tank 2 and blows toward the mopping and wiping member 101 of the cleaning robot 10, so that the mopping and wiping member is in an air circulation environment, which can effectively dry the mopping and wiping member 101 and prevent the mopping and wiping member 101 from becoming black and smelly. In addition, the wind generated by the fan 7 will also circulate in the sewage collection chamber. Since the base station performs cleaning work, some moisture remains inside the base station base 1. So that the base station base 1 is in an air circulation state, it can effectively dry the base station base 1 and prevent the sewage collection chamber from becoming black and smelly.

[0138] In addition, if Fig.17 As shown, the raised part 21 is also provided with a convex structure 233. When the cleaning robot is cleaning on the base station, when there is no convex structure 233, since the mopping member of the cleaning robot is on the convex part 21, the highest point of each convex part 21 can be on the same plane, that is, when the mopping member is cleaning, the bottom surface of the mopping member rubs against the convex part 21, which is equivalent to the friction between two planes. After the convex structure 233 is added to the convex part 21, when the mopping member is cleaning, the convex structure 233 can extend into the inner layer of the mopping member to scrape out the garbage and stains on the inner layer of the mopping member, which will improve the cleaning effect of the mopping member.

[0139] In the base station provided by the first embodiment of the present invention, when cleaning the mopping and wiping member, the protrusion 21 scrapes the garbage and stains on the mopping and wiping member onto the cleaning tank 2, and the sewage flows into the sewage collection cavity formed between the base station base 1 and the cleaning tank 2 through the drainage structure. After cleaning, the garbage on the cleaning tank 2 can be cleaned, and the base station is easy to clean and has low cleaning difficulty, thereby improving the user experience.

[0140] Second embodiment

[0141] Fig.18 The figure shows a base station provided by the second embodiment of the present invention. The difference from the first embodiment is that the anti-overflow contact sheet 6 is installed on the base station base 1, and the anti-overflow water outlet 28 of the first embodiment is no longer provided on the cleaning tank 2. The sewage flows into the base station base 1 after being filtered through the cleaning tank 2. When there is a problem with water absorption, the water will gradually overflow and soak the anti-overflow contact sheet 6, thereby realizing the anti-overflow function of the base station.

[0142] For example, the anti-overflow touch piece 6 is arranged in the sewage collection chamber and is located on the inner wall of the base station base 1. In the vertical direction, the anti-overflow touch piece 6 is located below the overflow water level of the base station base 1 and above the lowest point of the water level of the base station base 1.

[0143] In the second embodiment, the overflow prevention device can detect the situation that the water suction pipe 5 of the base station base 1 cannot pump water. When the cleaning water is sprayed out from the water spray pipe 4, it falls into the cleaning tank 2 and then flows from the cleaning tank 2 into the sewage collection chamber between the base station base 1 and the cleaning tank 2, and is sucked out of the sewage collection chamber by the water suction pipe 5. When the water suction pipe 5 cannot pump water, water overflows from the bottom of the sewage collection chamber. When the water contacts or soaks the overflow prevention contact piece 6, the control device of the overflow prevention device issues an alarm and / or controls the base station to stop supplying water to the liquid inlet structure.

[0144] Compared with the first embodiment, the cleaning tank 2 is no longer provided with the anti-overflow water outlet 28 of the first embodiment, which can avoid the false triggering of the anti-overflow caused by the cleaning water falling into the anti-overflow water outlet 28 when the water supply of the base station is too large or the cleaning water is slightly blocked in the cleaning tank.

[0145] Third embodiment

[0146] Figures 19 to 22 The base station provided by the third embodiment of the present invention is shown. The base station of the third embodiment of the present invention can be implemented based on any one of the above-mentioned embodiments one to two, and the base station of the third embodiment of the present invention also includes a box 9. The base station base 1 includes a base groove 11, a groove wall 12 arranged on the side of the base groove 11, a guide surface 13 gradually extending downward from one side of the base groove 11, and a guide plate 14 arranged on both sides of the guide surface 13, and the box 9 is connected to the groove wall 12 and the guide plate 14. The box 9 and the base station base 1 form a cavity structure, and the cavity structure includes a base station entrance 15 on the side close to the guide surface 13, and the cleaning tank 2 is located in the cavity structure. The cleaning tank 2 includes a tank body 22 and a handle 23, the tank body 22 is located on the base groove 11, and the handle 23 extends along the guide plate 14 toward the base station entrance 15.

[0147] The cleaning robot enters the base station through the base station entrance 15 to clean the mopping parts of the cleaning robot. The guide surface 13 is used to guide the cleaning robot into the base station, and the guide plates 14 arranged on both sides of the guide surface 13 are used to adjust the moving direction of the cleaning robot so that the cleaning robot reaches and stops at a preset cleaning position in the base station.

[0148] In addition, the cleaning tank 2 is provided with a support member 29 which is supported between the base station base 1 and the cleaning tank 2 and is used to limit the downward movement of the cleaning tank 2 .

[0149] In some modified embodiments of the third embodiment, the support member may also be arranged on the base station base 1 .

[0150] In the first to third embodiments, the cleaning tank 2 and the base station base 1 are detachably connected.

[0151] In the third embodiment, the cleaning tank 2 is located in the cavity structure formed by the box body 9 and the base station base 1. Since the cleaning tank 2 includes a tank body 22 and a handle 23, the handle 23 extends along the guide plate 14 toward the base station entrance 15. Thus, the user can conveniently remove the cleaning tank 2 detachably connected to the base station base 1 from the cavity structure by extracting the handle 23 near the base station entrance 15, so as to facilitate the user to clean the cleaning tank 2.

[0152] However, in some embodiments not shown in the figure, the cleaning tank 2 and the base station base 1 may also be fixedly connected or integrally formed. The fixedly connected connection may be, for example, welding, riveting, gluing, etc.

[0153] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
