[0073] In the related art, the filter inside the sewage tank is generally a large-size filter box. The large-size filter box makes the size of the installation cavity large. In the process of taking out the filter box and cleaning the filter box by the user, the user can clearly see the inside of the sewage tank through the large installation cavity, which affects the visual experience. The unpleasant odor inside the sewage tank also overflows through the large installation cavity at a fast speed, which easily causes the user to feel uncomfortable and is not conducive to improving the user experience.

[0074] Therefore, referring to FIGS. 1-8, the embodiment of the present application provides a sewage tank 120, which comprises a shell 150, a support body 12, and a filter 13. The shell 150 has a sewage cavity 11a, a sewage discharge channel 181, and an installation cavity 11c. The sewage cavity 11a is in communication with the sewage discharge channel 181 and the installation cavity 11c, respectively. The support body 12 is detachably connected with the shell 150. The filter 13 is connected with the support body 12. The filter 13 is at least partially located in the sewage discharge channel 181. The filter 13 is removed from the sewage tank 120 through the installation cavity 11c.

[0075] In the embodiment of the present application, the sewage in the sewage tank 120 is collected to the sewage discharge channel 181. In the plane intersecting with the extension direction of the sewage discharge channel 181, the cross-sectional area of the sewage discharge channel 181 is small. The filter 13 is at least partially located in the sewage discharge channel 181. The cross-sectional area of the filter 13 at least partially located in the sewage discharge channel 181 can also be set small to filter the sewage flowing through the sewage discharge channel 181. This is conducive to reducing the cross-sectional area of the filter 13. Under the flow of the sewage in the sewage tank 120, the filter material is easily collected in the filter 13, and then the user can easily clean the filter material collected in the filter 13. The cross-sectional area of the filter 13 can be reduced, which is also conducive to reducing the size of the installation cavity 11c. In the process of taking out the filter 13 to clean the filter material, the user can see the area of the inside of the sewage tank 120, which is conducive to improving the user's visual experience. Further, the small size of the installation cavity 11c can also slow down the speed of the unpleasant odor overflowing from the inside of the sewage tank 120, which is conducive to improving the user experience.

[0076] For example, referring to FIGS. 2 and 3, along the axial direction of the support body 12, the installation cavity 11c is located above the sewage discharge channel 181. The installation cavity 11c, the sewage cavity 11a, and the sewage discharge channel 181 are sequentially communicated from top to bottom, which is conducive to discharging the sewage in the sewage tank 120 from the sewage discharge channel 181.

[0077] It should be noted that the support body 12 is connected with the filter 13. The user can take out the filter 13 at least partially located in the sewage discharge channel 181 through the support body 12, or at least partially install the filter 13 in the sewage discharge channel 181 through the support body 12.

[0078] Exemplarily, referring to FIG. 2 and FIG. 3, the support body 12 is arranged in the installation cavity 11c, one end of the support body 12 along the axial direction is connected with the filter 13, and the other end of the support body 12 along the axial direction is located on the side of the shell 150 away from the sewage cavity 11a. The user can take out the filter 13 located at least partially in the sewage passage 181 through the support body 12, and the filter 13 sequentially passes through the sewage cavity 11a and the installation cavity 11c. When the filter 13 is located outside the sewage tank 120, the user can clean the filter material in the filter 13. When the user finishes cleaning the filter material in the filter 13, the user can install the filter 13 at least partially in the sewage passage 181 through the support body 12, and the filter 13 sequentially passes through the installation cavity 11c and the sewage cavity 11a.

[0079] Exemplarily, the material of the shell 150 is not limited. For example, the material of the shell 150 can be plastic or metal.

[0080] Exemplarily, the type of the filter 13 is not limited. For example, the filter 13 can be a filter box or a filter wire.

[0081] Exemplarily, the type of the support body 12 is not limited. For example, the support body 12 can be a rod with a certain hardness.

[0082] Exemplarily, the connection mode of the filter 13 and the support body 12 is not limited. For example, the filter 13 and the support body 12 can be detachably connected, or the filter 13 and the support body 12 can be fixedly connected.

[0083] In an embodiment, referring to FIG. 2, FIG. 3 and FIG. 5, the filter 13 is located in the sewage passage 181.

[0084] In the embodiment, the entire filter 13 is located in the sewage passage 181, so as to increase the volume of the filter 13 located in the sewage passage 181, and facilitate to improve the filtering effect of the filter 13.

[0085] Exemplarily, the distance of the filter 13 extending into the sewage passage 181 is not limited.

[0086] Exemplarily, referring to FIG. 2, FIG. 3 and FIG. 5, the position where the sewage cavity 11a and the sewage passage 181 are connected is an intersection surface, and the filter 13 can have a certain distance from the intersection surface.

[0087] Exemplarily, the filter 13 can also be flush with the intersection surface.

[0088] In an embodiment, referring to FIG. 2, FIG. 3 and FIG. 5, the filter 13 abuts against the inner wall of the sewage passage 181.

[0089] In the embodiment, the filter 13 abuts against the inner wall of the pollution discharge channel 181, which is beneficial to reduce the gap between the filter 13 and the inner wall of the pollution discharge channel 181, and then is beneficial to reduce the possibility of the filtered material flowing out of the pollution discharge channel 181 from the gap between the filter 13 and the inner wall of the pollution discharge channel 181, and is beneficial to improve the filtering effect of the filter 13.

[0090] It can be understood that the filter 13 can also not abut against the inner wall of the pollution discharge channel 181. For example, there is a small gap between the filter 13 and the inner wall of the pollution discharge channel 181.

[0091] In an embodiment, referring to FIGS. 2, 3, 5 and 8, the filter 13 includes a filter body 131 and bristles 132, the filter body 131 is connected with the support body 12, and the bristles 132 are arranged along the circumference of the filter body 131.

[0092] In the embodiment, the bristles 132 are arranged along the circumference of the filter body 131, so that the filtered material can be attached to the surface of the bristles 132, and in the process of cleaning the filtered material by the user, the user only needs to clean the filtered material on the outer surface of the filter 13, that is, the filtered material attached to the surface of the bristles 132, which is beneficial to improve the efficiency of the user in cleaning the filtered material in the filter 13.

[0093] It can be understood that the type of the filter 13 can not be limited. For example, the filter 13 can be a filter box, the filter box includes a filter box body and a filter screen, and the filter screen is located on the side wall and the bottom wall of the filter box body. When sewage passes through the filter box, the filtered material is filtered by the filter screen and remains in the filter box body. In the process of cleaning the filter box by the user, the user needs to reach into the inside of the filter box to clean the filtered material in the filter box.

[0094] For example, the arrangement mode of the bristles 132 can not be limited.

[0095] For example, referring to FIGS. 2, 3, 5 and 8, the number of the bristles 132 is a plurality, the plurality of bristles 132 are arranged along the axial direction of the support body 12, and the plurality of bristles 132 are all located in the pollution discharge channel 181.

[0096] For example, referring to FIGS. 2, 3, 5 and 8, the bristles 132 are arranged around the outside of the filter body 131.

[0097] For example, referring to FIGS. 2, 3, 5 and 8, the number of the bristles 132 is three, the three bristles 132 are arranged along the axial direction of the support body 12, the three bristles 132 are all arranged around the outside of the filter body 131, the three bristles 132 are all located in the pollution discharge channel 181, and the ends of the three bristles 132 away from the filter body 131 all abut against the inner wall of the pollution discharge channel 181.

[0098] Exemplarily, the number of the bristles 132 is three, the three bristles 132 are arranged axially spaced along the support body 12, the three bristles 132 are all wrapped outside the filter body 131, the three bristles 132 are all located in the pollution discharging channel 181, and the end of the three bristles 132 away from the filter body 131 is in a small gap with the inner wall of the pollution discharging channel 181.

That is, in the vertical direction, the height H1 of the water spraying element 1012 is not less than 2 / 3 of the height of the sewage cavity 101, that is, H1≥2 / 3H. The arrangement of the water spraying element 1012 in the height direction enables the clean water to clean the sewage cavity 101 from top to bottom, and the stains on the inner wall of the sewage cavity 101 close to the top can be flushed to the bottom of the sewage cavity 101, so that the sewage can be discharged from the sewage discharge channel 181, and excessive stains can be prevented from accumulating on the inner wall of the sewage cavity 101.

[0163] The embodiment of the application enables the water spraying element to extend into the sewage cavity to a sufficient height, so that the upper part of the inner wall of the sewage cavity can also be cleaned, the cleaning blind area of the water spraying element is reduced, the cleaning effect of the water spraying element is improved, and the performance of the product is optimized.

[0164] In some embodiments, as shown in FIG. 10, the sewage cavity 101 is also provided with a sewage inlet 123, and the sewage cavity 101 is provided with a sewage float 1015. The height difference between any two of the installation positions of the sewage inlet 123, the sewage float 1015 and the water spraying element 1012 in the vertical direction is less than a first distance D1. That is, the sewage float 1015 in the sewage cavity 101 is located at the water level line that can accommodate the maximum sewage capacity in the sewage cavity 101. In the vertical direction, the sewage inlet 123 is arranged above the highest water level line, and the height of the water spraying element 1012 is also arranged above the highest water level line. The height difference between the sewage inlet 123, the sewage float 1015 and the water spraying element 1012 in the vertical direction is small, so that the positions in the sewage tank that contact the sewage can be sprayed by the clean water.

[0165] The embodiment of the application limits the height of the sewage inlet, the sewage float and the water spraying pipe, so that the clean water sprayed by the water spraying element can contact the contaminated area in the sewage cavity, avoid the cleaning blind area, improve the cleaning quality, ensure the self-cleaning effect of the sewage tank, and improve the user's use experience.

[0166] In some embodiments, as shown in FIG. 13, the sewage inlet 123 of the sewage chamber 101 and the clean water inlet 1011 of the sewage chamber 101 are spaced apart by a second distance D2 in the horizontal direction, and the second distance D2 is greater than or equal to 1 / 2 of the length D of the sewage tank 101 extending in the horizontal direction. It can be understood that, in the horizontal direction, when the distance between the sewage inlet 123 and the clean water inlet 1011 is small, the sewage will contaminate the water jet 1012 when entering the sewage chamber 101, thereby affecting the cleaning effect, and therefore, it is necessary to limit the distance between the sewage inlet 123 and the clean water inlet 1011, i.e., D2≥1 / 2D.

[0167] In the embodiments of the present application, by controlling the distance between the clean water inlet and the sewage inlet in the sewage tank, the sewage is prevented from contaminating the clean water inlet and affecting the cleaning effect, the cleaning quality is further improved, and the product performance is optimized.

[0168] In some embodiments, as shown in FIG. 10, one end of the second pipeline 113 is connected with the water distribution piece 1200, and the other end is connected with the clean water inlet 111, which is arranged at the bottom of the clean water chamber 102. That is, when the water flow pipeline 11 is in the second state B, the second pipeline 113 is in communication with the water inlet pipeline 1110, and at this time, the clean water can enter the clean water chamber 102 from the bottom of the clean water chamber 102 through the clean water inlet 111.

[0169] Similarly, the clean water chamber 102 is also provided with a clean water float 1022, one end of the clean water float 1022 is connected with the clean water inlet 111, and as the water level in the clean water chamber 102 increases, the end of the clean water float 1022 away from the clean water inlet 111 gradually rises with the water level. When the clean water float 1022 rises to the horizontal (the highest point of the water level allowed to be contained), the end of the clean water float 1022 connected with the clean water inlet 1021 will block the clean water inlet 1021, so that the clean water cannot enter the clean water chamber 102 any more, thereby playing a role of controlling the water amount.

[0170] In the embodiments of the present application, the inlet of the clean water chamber is arranged at the bottom of the clean water chamber, and the water amount in the clean water chamber is controlled by the clean water float, thereby simplifying the structure of the water inlet and outlet assembly, reducing the production cost and installation difficulty.

Wherein the cleaning base station 100 is used for cleaning the surface to be cleaned, and the base station 3 comprises a water supply and drainage assembly 10000. The clean water cavity 102 is used for providing clean water for the cleaning base station 100, and the sewage cavity 101 is used for collecting sewage generated by the cleaning base station 100. It can be understood that the cleaning base station 100 is used for moving and cleaning the surface to be cleaned, and when the cleaning base station 100 completes a certain amount of cleaning, the cleaning base station 100 will automatically return to the base station 3, and after the cleaning of the cleaning base station 100 is completed in the base station 3, the cleaning base station 100 will again drive out of the base station 3 to continue cleaning the surface to be cleaned.

[0172] During the cleaning process of the cleaning base station 100 in the base station 3, the water supply and drainage assembly 10000 in the base station 3 works, wherein the clean water stored in the clean water cavity 102 can clean the cleaning base station 100, and the sewage generated during the cleaning process can enter the sewage cavity 101 through the sewage inlet 123. When the sewage cavity needs to be cleaned, the water flow pipeline 11 is adjusted to the first state A to complete the self-cleaning of the sewage cavity 101, without the need for the user to disassemble the sewage cavity 101 for cleaning.

[0173] The application embodiment provides a cleaning device which can perform self-cleaning of the sewage cavity, so that the user does not need to clean the sewage cavity by himself, simplifies the operation, improves the automation degree of the product, and is beneficial to improving the user's use experience.

[0174] The cleaning base station of the application can automatically clean the residual stains on the inner wall of the sewage tank. The user only needs to continuously supply clean water to the clean water tank of the cleaning device. Through the structure inside the cleaning base station, the clean water can be sprayed to the inner wall of the sewage tank to wash the residual stains attached to the inner wall, so that the cleaning work of the sewage tank can be completed without the user's manual operation.

[0175] The cleaning base station of the application can clean the sewage tank according to the user's needs at a predetermined frequency, thereby reducing the serious accumulation of residual stains on the inner wall of the sewage tank and reducing the probability of blocking the downstream pipeline of the sewage tank. Therefore, the cleaning base station of the application meets the requirements of long-term use and reduced maintenance time of the user.

[0176] The cleaning base station of the application is suitable for cleaning robots and can clean the cleaning cloth of the cleaning robot. The cleaning base station can be cleaned while the cleaning robot is cleaned and maintained, so that the cleaning base station can work for a long time and the maintenance time and cost of the cleaning base station are reduced.

[0178] The cleaning base station of the present application can temporarily store a certain amount of sewage in the sewage tank during the cleaning process of other objects to be cleaned, and finally periodically discharge the sewage to the external environment. In order to ensure that the sewage tank of the cleaning base station has good cleanliness, the structure of the clean water tank and the sewage tank is improved without increasing other equipment and costs, so as to achieve the purpose of cleaning the sewage tank.

[0188] The shell 150 of the cleaning base station 100 is provided with a cleaning tank, a clean water cavity, a sewage cavity, and a pipeline assembly. The cleaning assembly further includes a pumping assembly 160 and a suction assembly 170. The pumping assembly 160 is connected to the clean water cavity and the cleaning tank through the pipeline assembly, respectively, for pumping the clean water in the clean water cavity into the cleaning tank. The suction assembly 170 is connected to the cleaning tank and the sewage cavity through the pipeline assembly, respectively, for pumping the sewage in the cleaning tank into the sewage cavity.

[0189] The clean water cavity of the cleaning base station 100 can be independently provided as a clean water tank 110, and the sewage cavity can be independently provided as a sewage tank 120. In the following different embodiments, the clean water tank 110 and the sewage tank 120 are taken as examples. It can be understood that when the cleaning base station 100 is required to be provided as an integral structure, as shown in FIG. 17, the clean water cavity and the sewage cavity can be arranged in the shell 150 of the cleaning base station 100, respectively.

[0190] In the cleaning base station 100 of the present embodiment, the clean water tank 110, the sewage tank 120, the pumping assembly 160, and the suction assembly 170 form a water supply and drainage device, or an automatic water supply and drainage device. When the mop in the cleaning tank needs to be cleaned, the pumping assembly 160 is used to pump clean water into the cleaning tank. After cleaning, the suction assembly 170 is used to pump the sewage in the cleaning tank into the sewage tank 120.

[0191] In order to clean the residual stains on the inner wall of the sewage tank 120, the water supply and drainage device or the automatic water supply and drainage device is improved, the overflow port 112 is arranged on the clean water tank 110, and the spray port 121 is arranged on the sewage tank 120, wherein the spray port 121 faces the inner wall of the sewage tank 120, the overflow port 112 and the spray port 121 are connected through the pipeline 130, and FIG. 20 is a perspective view of the shell 220 of the cleaning base station 100, wherein the overflow port 112 and the spray port 121 connected through the pipeline 130 are shown, as shown in FIG. 20, the clean water in the clean water tank 110 can enter the pipeline 130 through the overflow port 112, and is sprayed to the inner wall of the sewage tank 120 through the spray port 121 connected with the pipeline 130, so as to clean the residual stains on the inner wall of the sewage tank 120.

[0192] The overflow port 112 can be arranged at a suitable position of the clean water tank 110 according to needs, such as the top of the clean water tank 110, the side of the clean water tank 110 or the bottom of the clean water tank 110, and the spray port 121 is arranged at the top or the side of the sewage tank 120. The spray port 121 can be arranged in multiple, and the multiple spray ports 121 are respectively directed to different inner walls of the sewage tank 120, so that different positions of the sewage tank 120 can be cleaned, and stains at different positions can be cleaned.

[0193] In an embodiment of the present application, the overflow port is arranged at the top of the clean water tank, and the spray port is arranged at the top of the sewage tank. When the overflow port and the spray port are connected through the pipeline, during the process of injecting clean water into the clean water tank, after the clean water tank is filled with clean water, the clean water flows to the spray port of the sewage tank along the overflow port and the pipeline. The clean water cleans the inner wall of the sewage tank through the spray port at the top of the sewage tank, and the corners of the sewage tank are cleaned by using the gravity of the clean water.

[0194] In an embodiment of the present application, the clean water tank and the sewage tank of the cleaning base station are in a split type, and the clean water tank and the sewage tank are arranged independently. The split type structure of the clean water tank and the sewage tank is beneficial to the maintenance of different parts of the cleaning base station, such as the independent replacement or maintenance of the clean water tank or the sewage tank.

[0195] In an embodiment of the present application, the clean water tank and the sewage tank of the cleaning base station are integrally formed. Such arrangement can reduce multiple processes during the processing and manufacturing of the cleaning base station, and the clean water tank and the sewage tank are completed in the same process. Meanwhile, the structure of the cleaning base station is more compact, which is beneficial to reducing the volume of the cleaning base station.

[0196] Fig. 18 is a schematic view of the internal structure of the cleaning base station according to an embodiment of the present application. As shown in Fig. 18, the cleaning base station 100 is provided with a clean water tank 110 and a dirty water tank 120, and the clean water tank 110 and the dirty water tank 120 are at substantially the same horizontal level. As can be seen from Fig. 18, the clean water tank 110 and the dirty water tank 120 each occupies a large space, and the cleaning base station 100 needs to store a certain amount of clean water and temporarily store a certain amount of dirty water.

[0197] The designer can also rearrange the volumes of the clean water tank 110 and the dirty water tank 120 according to the specific circumstances of the cleaning base station 100. For example, the volume of the clean water tank 110 can be set to be greater than the volume of the dirty water tank 120, so as to reduce the number of times of delivering clean water into the clean water tank 110. The volume of the dirty water tank 120 can also be set to be greater than the volume of the clean water tank 110, so as to temporarily store more dirty water and clean more rags at one time.

[0198] In an embodiment of the present application, in order to more conveniently clean the residual stains in the dirty water tank 120, a water level detection member can also be arranged in the clean water tank 110. The cleaning base station 100 comprises a control device, which is electrically connected with the water level detection member to obtain the water level information in the clean water tank 110. The control device is also connected with the water supply assembly 140 to control the water supply assembly 140 to supply clean water into the clean water tank 110, and according to the water level in the clean water tank 110 provided by the water level detection member, the control device controls the water supply assembly 140 to supply clean water into the clean water tank 110 until the water level in the clean water tank 110 is above the overflow port 112.

[0199] The clean water tank is provided with a clean water inlet 111, and the water supply assembly delivers clean water into the clean water tank through the clean water inlet 111.

[0200] It should be noted that during the process of cleaning the stains on the inner wall of the dirty water tank 120, the water level in the clean water tank 110 needs to be always above the overflow port 112, that is, the water supply assembly 140 needs to continuously supply clean water into the clean water tank 110 to enable the clean water to overflow into the spray port 121 and clean the inner wall of the dirty water tank 120.

[0201] In an embodiment of the present application, the water supply assembly 140 comprises a water pump and a water pump pipe connected with the water pump. The water inlet of the water pump is connected to a tap valve through the water pump pipe, and the tap valve is in a normally open state. The control device controls the water pump to pump clean water into the clean water tank 110 according to the water level detection member, so that the water level in the clean water tank 110 is above the overflow port 112, and thus the clean water can flow into the spray port 121 through the overflow port 112 to clean the residual stains on the inner wall of the dirty water tank 120.

[0202] The clean water in the clean water tank 110 can flow to the spray port 121 in the sewage tank 120 through the overflow port 112, and the level of the overflow port 112 is higher than that of the spray port 121.

[0203] The water pump can be arranged between the overflow port 112 of the clean water tank 110 and the spray port 121 of the sewage tank 120, and the water in the clean water tank 110 can be supplied to the spray port 121 through the overflow port 112, regardless of whether the level of the overflow port 112 is the same as that of the spray port 121.

[0204] In an embodiment of the present application, the overflow port 112 of the clean water tank 110 is arranged at the top of the clean water tank 110, and the clean water can be supplied to the spray port 121 of the sewage tank 120 through the overflow port 112 only when the clean water tank 110 is filled with clean water. In this embodiment, the control device obtains the water level in the clean water tank 110 through the water level sensor, and clean water is continuously pumped into the clean water tank 110 even when the clean water tank 110 is full, so that the clean water can flow to the spray port 121 of the sewage tank 120 through the overflow port 112 to clean the residual stains in the sewage tank 120.

[0205] In an embodiment of the present application, the cleaning base station 100 can further comprise a signal shielding unit arranged in the clean water tank 110 and close to the water level detection component. The signal shielding unit is used to control the signal communication or disconnection between the control device and the water level detection component, or the signal shielding unit is electrically connected to the water level detection component to shield the detection signal of the water level detection component. In this embodiment, the control device does not need to obtain the water level information in the clean water tank 110 through the water level detection component, and the water supply component 140 continuously supplies clean water to the clean water tank 110, so that the clean water in the clean water tank 110 can be sprayed to the inner wall of the sewage tank 120 through the overflow port 112 and the spray port 121 to clean the stains on the inner wall.

[0206] More specifically, the signal shielding unit can include a control switch. When the control switch is in the off condition, the water level signal obtained by the water level detection component stops being transmitted to the control device, so that the control device does not need to know the water level information in the clean water tank, and the water supply component continuously supplies clean water to the clean water tank.

[0207] The signal shielding unit can also be arranged as a control module inside the control device to shield the water level information of the water level detection component through logical control to prevent the control device from controlling the water supply component to stop supplying water to the clean water tank when the clean water tank is full.

[0208] The signal shielding unit can also be arranged in a processor on the main plate of the cleaning base station, wherein the water level detection member is arranged in the processor, and the signal shielding unit is electrically connected to the water level detection member in the same processor, for controlling the signal communication or disconnection between the control device and the water level detection assembly in the cleaning base station. When the signal between the control device and the water level detection member is disconnected, clean water will continue to be injected into the clean water tank in the cleaning base station, and flow to the spray opening of the sewage tank through the pipeline.
