Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, in particular to a cleaning base station. BACKGROUND

[0002] With the development of household cleaning equipment and the increasing demand of household users for cleaning effect, the scrubber is favored by consumers due to its high efficiency, convenience, environmental protection and dry-wet dual use characteristics. The scrubber is usually equipped with a cleaning base station, which can automatically clean and maintain the scrubber, such as automatically adding water, automatically charging, washing the sewage tank, and discharging sewage, so as to further free the hands of the user.

[0003] In the prior art, the cleaning base station generally discharges the dirt after self-cleaning into the sewer through a sewage discharge hose. Due to the long length of the sewage discharge hose, there is a risk of dirt being stuck after the hose is bent. In addition, the position of the sewage discharge port of the cleaning base station on the market is single and cannot be selected. The user needs to adjust the placement mode of the cleaning base station according to the position of the sewage discharge port and the sewer, which occupies a large installation space and limits the installation position, thereby causing poor user experience. CONTENT OF THE UTILITY MODEL

[0004] The present disclosure provides a cleaning base station to solve the problems in the prior art.

[0005] According to a first aspect of the present disclosure, a cleaning base station is provided, comprising:

[0006] a base station body configured to support a cleaning equipment;

[0007] a sewage discharge mechanism configured to be installed on the base station body and used to discharge the dirt collected by the cleaning equipment to the outside of the base station body through the sewage discharge mechanism;

[0008] The sewage discharge mechanism comprises a sewage discharge port with an opening facing downward, which is configured to be connected with an external sewer; wherein the sewage discharge port is configured to be located in the projection plane of the base station body in the height direction.

[0009] In some embodiments, the sewage discharge port is configured to protrude from the bottom end surface of the base station body to directly connect with the external sewer.

[0010] One beneficial effect of the present disclosure is that the drain outlet of the drainage mechanism can be directly connected with the external ground drain, and the dirt from the cleaning device is first drained into the drainage tank, and then enters the drainage mechanism through the connecting port, and is directly drained into the ground drain through the drain outlet. The present disclosure does not need to additionally set a drainage hose to connect the drain outlet and the ground drain, but can directly drain in a direct drainage manner, thereby fundamentally solving the problem that the drainage hose is easily blocked by dirt after being bent. In addition, the drain outlet of the present disclosure is located in the projection plane of the base station body in the height direction, thereby ensuring that the overall floor area of the cleaning base station will not increase due to the setting of the drainage mechanism, thereby saving the space for installing the cleaning base station, and facilitating the user to plan the placement position of the cleaning base station.

[0011] Other features of the present disclosure and its advantages will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0029] In this document, "upper", "lower", "front", "rear", "left", "right", and the like are used to describe relative positions between the relevant parts, and are not intended to limit the absolute positions of the relevant parts.

[0030] In this document, "first", "second", and the like are used to distinguish between items from one another, and are not intended to indicate importance and order, and the existence of one another.

[0031] In this document, "equal", "same", and the like are not strictly limited in the mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and allowed in manufacturing or use, etc.

[0032] The present disclosure provides a cleaning base station for use in cooperation with a cleaning device for cleaning a work surface such as a floor or a carpet, wherein the cleaning device and the cleaning base station can be docked with each other so that the cleaning device can discharge dirty water into the cleaning base station, and the cleaning base station can also charge the cleaning device, replenish cleaning liquid, etc.

[0033] The cleaning device can be a handheld cleaning device such as a handheld cleaner, a handheld wet vacuum cleaner, a handheld floor cleaner, a handheld fabric cleaner, etc. known to those skilled in the art, or a floor cleaning robot, a sweeping and mopping robot, etc. known to those skilled in the art. The cleaning device at least includes a body and a dirty water tank 3. It can be understood that the cleaning device can also include a floor brush assembly, a cleaning liquid tank, etc., wherein the body serves as a carrier for mounting various functional elements required by the cleaning device.

[0034] The floor brush assembly of the cleaning device is arranged at the bottom end of the body and is used to clean a work surface such as a floor, a carpet, or a furniture surface. The floor brush assembly and the body can be arranged with a pivot shaft, and the floor brush assembly can rotate relative to the body via the pivot shaft, so that the user can drag the cleaning device back and forth to clean the work surface. When cleaning the work surface, the floor brush assembly is always attached to the work surface to wipe off stains on the work surface.

[0035] The dirty water tank 3 of the cleaning device is used to contain dirt sucked from the work surface, which can be dirty water generated during cleaning or various garbage sucked from the work surface. Figure 1 The dirty water tank 3 is used to dock with the cleaning base station, so that the dirt in the inner cavity of the dirty water tank 3 is discharged into the cleaning base station (the complete cleaning device is not shown in the figure, and only the dirty water tank 3 of the cleaning device is shown for simplicity).

[0036] Referring to Figure 1 and Figure 2 , the cleaning base station of the present disclosure includes a base station body 1 and a dirty water discharge mechanism 2. The base station body 1 is configured to support the cleaning device. In an embodiment of the present disclosure, the base station body 1 includes a body 13 and a tray 14. The body 13 is configured to extend in the height direction and is used to mount various functional elements of the base station body 1. The tray 14 is arranged at the bottom of the body 13 and extends forward relative to the body 13 in the horizontal direction. The side opposite to the front side is referred to as the rear side. The tray 14 is mainly used to support the floor brush assembly of the cleaning device when the cleaning device is docked with the cleaning base station for dirty water discharge. The tray 14 can also be used to clean the floor brush assembly or charge the cleaning base station.

[0037] As Figure 1As shown, the base station body 1 is provided with a sewage tank 11, and the bottom of the sewage tank 11 is provided with a docking interface 111. The sewage tank 11 can be arranged in the machine body 13, and a protruding platform for docking the sewage tank 3 of the cleaning device is arranged on the front side wall of the machine body 13. When the cleaning device is parked at the cleaning base station, the sewage tank 3 is docked to the protruding platform, and the dirt in the sewage tank 3 can be discharged into the sewage tank 11 under the action of its own gravity.

[0038] In one embodiment of the present disclosure, a filter assembly 12 is arranged in the sewage tank 11, and the filter assembly 12 can be a filter screen arranged on the sewage discharge path. It can be understood that, in addition to liquid such as sewage, the dirt from the sewage tank 3 of the cleaning device also contains solid waste such as hair, paper, and debris. During the process of discharging the sewage to the ground, the solid waste is easy to cause blockage. Therefore, the present embodiment is provided with the filter assembly 12 in the sewage tank 11, so as to filter the dirt entering the sewage tank 11, and the solid waste can be filtered out by the filter assembly 12, thereby avoiding the problem of blockage of the ground drain.

[0039] As shown in Figure 1 The sewage discharge mechanism 2 is configured to be mounted on the base station body 1, and is used for discharging the dirt collected by the cleaning device to the outside of the base station body 1 through the sewage discharge mechanism 2. Specifically, the sewage discharge mechanism 2 is in communication with the docking interface 111 of the sewage tank 11, so that the dirt in the sewage tank 11 can be discharged into the sewage discharge mechanism 2 through the docking interface 111. The sewage discharge mechanism 2 includes a sewage discharge port 211 opening downward, and the sewage discharge port 211 is configured to protrude from the bottom end face of the base station body 1, so as to be docked with the ground drain outside. The sewage discharge port 211 is configured to be located in the projection plane of the base station body 1 in the height direction. In the actual use scenario, the ground drain is usually flush with the ground or lower than the ground, and the cleaning base station is provided with a support column on the bottom face, so that the sewage discharge port 211 protruding from the bottom end face of the base station body 1 can be inserted into the ground drain downward, so as to be directly connected with the ground drain.

[0040] The dirt from the cleaning device is first discharged into the sewage tank 11, and then enters the sewage discharge mechanism 2 through the docking interface 111, and is directly discharged into the ground drain through the sewage discharge port 211. The present disclosure does not need to additionally arrange a sewage discharge hose to connect the sewage discharge port 211 and the ground drain, but can directly discharge the sewage in a direct discharge manner, thereby solving the problem that the sewage discharge hose is easy to be blocked by dirt after being bent. In addition, the sewage discharge port 211 of the present disclosure is located in the projection plane of the base station body in the height direction, so as to ensure that the overall floor area of the cleaning base station will not be increased due to the arrangement of the sewage discharge mechanism 2, thereby saving the space for installing the cleaning base station, and facilitating the user to plan the placement position of the cleaning base station.

[0041] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2, the sewage mechanism 2 comprises a base 20 and a sewage passage 21 located on the base 20, one end of the sewage passage 21 is configured as a communication port 212 for receiving dirt. The communication port 212 can be located in the middle region of the base 20 to communicate with the docking port 111, and the sewage port 211 is located at the other end of the sewage passage 21. Among them, the base 20 is the main structure of the sewage mechanism 2, the sewage passage 21 is arranged inside the base 20, and the sewage passage 21 penetrates the base 20. In the actual use scene, the upper opening of the sewage passage 21 is the communication port 212, which is docked and communicated with the docking port 111, so that the dirt in the sewage groove 11 can be discharged into the sewage passage 21 through the communication port 212; the lower opening of the sewage passage 21 is the sewage port 211, and the dirt entering the sewage passage 21 from the communication port 212 flows to the sewage port 211 under the action of gravity (or assisted by additional positive pressure), thereby flowing to the ground drain directly connected with the sewage port 211 for discharge.

[0042] In one embodiment of the present disclosure, referring to Figure 7 , at least one end of the sewage passage 21, i.e. the sewage port 211, is configured as a frustum from top to bottom. The sewage port 211 is used for docking to the ground drain, and the frustum configuration makes it easier for the sewage port 211 to extend into the ground drain and firmly clamp with the ground drain, thereby avoiding water leakage at the connection position. In addition, since the flow rate of liquid is inversely proportional to the pipe diameter, the present disclosure configures the position of the sewage port 211, or even the entire sewage passage 21 as a frustum with a wide top and a narrow bottom, so that the pipe diameter gradually decreases in the flow direction, thereby gradually increasing the flow rate, which helps to improve the efficiency of drainage.

[0043] In one embodiment of the present disclosure, as shown in Figure 2 , Figure 3 , Figures 8 to 10 , the sewage passage 21 is provided with a sealing element 27 at one end of the sewage port 211, and the sealing element 27 is configured to seal the sewage passage 21 and the ground drain. The sealing element 27 is configured as a frustum from top to bottom. The sealing element 27 can be sleeved at one end of the sewage port 211 of the sewage passage 21, and the sealing element 27 has a certain elasticity or is configured to be movable. When the ground drain is docked, the frustum-shaped sealing element 27 can easily extend into the ground drain and tightly fit the inner wall of the ground drain, thereby firmly docking the sewage port 211 and the ground drain together. By providing the frustum-shaped sealing element 27, the present disclosure avoids water leakage and odor at the connection position of the sewage port 211 and the ground drain, and improves the firmness and tightness of the docking.

[0044] In one embodiment of the present disclosure, the sewage mechanism 2 is configured to be detachably mounted on the base station body 1. A mounting groove can be provided at the bottom of the base station body 1, which is matched with the sewage mechanism 2 in shape, and a quick-release component can be provided inside the mounting groove. The user can mount or detach the sewage mechanism 2 from the mounting groove. In the mounted state, the communication port 212 of the sewage mechanism 2 is connected and communicated with the docking port 111 at the bottom of the base station body 1; in the detached state, the communication port 212 of the sewage mechanism is separated from the docking port 111 at the bottom of the base station body 1. In this way, the sewage mechanism 2 is modularized, and the same base station body 1 can be matched with different sewage mechanisms 2. The user can select different sewage mechanisms 2 according to the specific use scenario and assemble them by himself to adapt to different home situations.

[0045] Specifically, the floor drain in different home environments can be arranged at different positions. Some floor drains are arranged at the wall position, and some floor drains are arranged at the corner position. Since the present disclosure adopts the direct drainage mode for sewage discharge, the sewage mechanism 2 is directly connected to the floor drain through the sewage outlet 211. Therefore, in order to adapt to the arrangement position of the floor drain in different homes, the arrangement position of the sewage outlet 211 on the sewage mechanism 2 needs to have multiple choices, and the user can select the appropriate sewage mechanism 2 according to the layout of his own home.

[0046] Based on this, the present disclosure provides two specific structural embodiments of the sewage mechanism 2. The sewage outlet 211 in the two embodiments can be arranged at different positions, and the two embodiments can be respectively applied to the home environment where the floor drain is arranged at the wall position and the corner position. It should be noted that the two embodiments provided by the present disclosure are only examples. In addition to the following two specific embodiments, the sewage outlet 211 can also be arranged in other ways, and the various functional components in the sewage mechanism 2 can also be adjusted accordingly, which are not limited by the present disclosure.

[0047] Embodiment one: middle direct drainage

[0048] In one embodiment of the present disclosure, referring to Figure 2 , Figure 3 , Figure 7 and Figure 8The sewage passage 21 is located in the middle area at the back of the base station body 1, and the sewage passage 21 is configured to extend vertically downward from the communication port 212 to the sewage port 211, so that the sewage port 211 is located in the projection plane of the communication port 212 in the height direction. As described above, the front of the base station body 1 is provided with a tray 14 for receiving the floor brush assembly, and the sewage tank 11 is located in the rear body 13, so the sewage mechanism 2 for docking with the docking port 111 must be installed in the rear area. Since the docking port 111 of the sewage tank 11 is located in the middle of the base station body 1, the communication port 212 for docking with the docking port 111 is also located in the middle of the base station body 1. The sewage passage 21 extends vertically downward in the middle area at the back of the base station body 1, and under the action of gravity, the dirt from the sewage tank 11 can flow in the sewage passage 21 to the sewage port 211 through the communication port 212, and then quickly discharged to the ground. The present embodiment sets the sewage port 211 in the middle area at the back of the base station body 1, which can be applied to the case where the ground drain is arranged at the wall position.

[0049] In one embodiment of the present disclosure, referring to Figure 2 、 Figure 3 and Figure 8 , the sewage mechanism 2 further comprises a flushing assembly, which can be used to flush at least the sewage passage 21, thereby playing a role in assisting sewage and avoiding blockage on the one hand, and maintaining the cleanliness of the sewage passage 21 and avoiding dirty wall hanging and odor on the other hand. Specifically, the flushing assembly comprises a water injection valve 22 arranged on the base 20, and at least one flushing pipeline 23 in communication with the water injection valve 22, and the water flow in the flushing pipeline 23 is configured to flow into the sewage passage 21 to flush the sewage passage 21.

[0050] The water injection valve 22 can be located at the top side of the sewage mechanism 2, as shown in Figure 3 , the water injection valve 22 can be provided with only one side, as shown in Figure 8 , the water injection valve 22 can also have two, and the two water injection valves 22 can be symmetrically arranged on both sides of the sewage mechanism 2. Each water injection valve 22 can correspondingly provide a flushing pipeline 23, thereby forming a water flow path between the water injection valve 22 and the sewage passage 21. As shown in Figure 2 , a pipe joint 15 can be provided at the bottom of the base station body 1 corresponding to the position of the water injection valve 22 of the sewage mechanism 2, and when the sewage mechanism 2 is installed on the base station body 1, the pipe joint 15 can be docked with the water injection valve 22. The pipe joint 15 is used to provide cleaning liquid to the flushing assembly, and in the installed state, the passage between the pipe joint 15 and the water injection valve 22 is open, and the cleaning liquid stored in the base station body 1 can flow into the flushing pipeline 23 through the pipe joint 15 and the water injection valve 22, thereby being able to flush the sewage passage 21.

[0051] In one embodiment of the present disclosure, the circumferential direction of the blowdown channel 21 is provided with an annular channel 26, the flushing pipe 23 is communicated to the annular channel 26, and the annular channel 26 is communicated to the blowdown channel 21, so that the liquid in the flushing pipe 23 can flow into the blowdown channel 21 through the annular channel 26, thereby flushing the blowdown channel 21. A plurality of drain openings 260 can be arranged on the bottom surface of the annular channel 26, and the plurality of drain openings 260 are distributed in the circumferential direction of the bottom surface of the annular channel 26. After the liquid flowing out of the flushing pipe 23 enters the annular channel 26, it can flow to the blowdown channel 21 from the plurality of drain openings 260.

[0052] Specifically, in one embodiment of the present disclosure, referring to Figures 3 to 6 , the blowdown channel 21 includes a first blowdown pipe 24 and a second blowdown pipe 25 that are butted together, wherein the upper opening of the first blowdown pipe 24 forms a communication port 212 for butt joint with the butt joint 111, and the lower opening of the second blowdown pipe 25 forms a blowdown port 211 for butt joint with the ground, wherein the lower end of the first blowdown pipe 24 extends into the upper opening of the second blowdown pipe 25, thereby forming a blowdown channel 21 extending vertically downward.

[0053] As shown in Figure 4 , the first blowdown pipe 24 and the second blowdown pipe 25 enclose an annular channel 26 with a drain opening 260 at the position where they are connected. The flushing pipe 23 is configured to be communicated with the annular channel 26, and the liquid in the flushing pipe 23 is configured to flow downward from the drain opening 260 after entering the annular channel 26. The space below the drain opening 260 is the inner cavity of the second blowdown pipe 25. After the liquid in the flushing pipe 23 flows into the annular channel 26, it can flow around the first blowdown pipe 24 along the annular channel 26 and flow downward into the second blowdown pipe 25 through the drain opening 260, thereby flushing the second blowdown pipe 25.

[0054] Referring to Figure 3 and Figure 4 , the second blowdown pipe 25 includes a first portion 251 and a second portion 252, the diameter of the first portion 251 is greater than the diameter of the second portion 252, and the first portion 251 at least includes an inclined surface extending downwardly and inclinedly to the connection with the second portion 252. In the vertical direction, the first portion 251 is directly opposite the drain opening 260, and the water flowing downward from the drain opening 260 falls onto the inner wall surface of the first portion 251 and then flows to the second portion 252 through the inclined surface of the first portion 251. In this way, the inner wall surface of the second blowdown pipe 25 is simultaneously flushed.

[0055] As shown in Figure 3As shown, the height position of the flushing pipe 23 is substantially flush with the annular channel 26, i.e. the flushing pipe 23 is substantially flush with the lower position of the first drain pipe 24. It can be understood that the first drain pipe 24 used for directly connecting to the base station body 1 has a large pipe diameter, and it is difficult to be blocked even without flushing, and the liquid in the flushing pipe 23 is difficult to flow upward against gravity. Therefore, the flushing assembly of the present disclosure can not flush the entire drain channel 21, but only flush the annular channel 26 and the second drain pipe 25 below it. In this way, the waterway design inside the drain mechanism 2 is simplified, and the flushing pipe 23 can extend substantially in the horizontal direction to communicate with the annular channel 26, thereby flushing part of the drain channel 21.

[0056] In an embodiment of the present disclosure, a plurality of drain openings 260 can be provided, and the plurality of drain openings 260 are distributed in the circumferential direction of the bottom of the annular channel 26. The liquid in the annular channel 26 can flow uniformly in the circumferential direction and flow into the second drain pipe 25 through different drain openings 260. The present disclosure provides a plurality of drain openings 260 in the circumferential direction of the bottom of the annular channel 26, so that the liquid can flow into the second drain pipe 25 from different positions in the circumferential direction of the second drain pipe 25, and the water flow force and gravity of the water flow from the drain openings 260 can flush away the dirt, thereby achieving comprehensive flushing of the second drain pipe 25 while preventing blockage of the flushing pipe.

[0057] In an embodiment of the present disclosure, as shown in the drawings, Figure 5 As shown, a first flange 241 protruding outward is arranged on the outer wall of the first drain pipe 24 and / or the inner wall of the second drain pipe 25, and a second flange 242 lower than the first flange 241 in the height direction is arranged on the outer wall of the first drain pipe 24 and / or the inner wall of the second drain pipe 25, and the first flange 241, the second flange 242, the outer wall of the first drain pipe 24 and the inner wall of the second drain pipe 25 form the annular channel 26. In this embodiment, the first flange 241 and the second flange 242 are arranged on the outer wall of the first drain pipe 24, and in other embodiments, one or both of the first flange 241 and the second flange 242 can also be arranged on the inner wall of the second drain pipe 25, which is not limited in the present disclosure.

[0058] The first flange 241 and the second flange 242 arranged on the outer wall of the first drain pipe 24 extend in the radial direction to abut the inner wall of the second drain pipe 25, thereby forming the annular channel 26. Specifically, the lower wall of the first flange 241 forms the upper surface of the annular channel 26, the upper wall of the second flange 242 forms the lower surface of the annular channel 26, the outer wall of the first drain pipe 24 forms the inner surface of the annular channel 26, and the inner wall of the second drain pipe 25 forms the outer surface of the annular channel 26. The second drain pipe 25 is provided with a hollow portion corresponding to the position of the flushing pipe 23, so that the annular channel 26 communicates with the flushing pipe 23.

[0059] As shown in Figure 5 , the lower water outlet 260 is a notch 2421 arranged at the edge of the second flange 242. The edge of the second flange 242 without the notch 2421 can tightly fit the inner wall of the second drain pipe 25, while the edge at the position of the notch 2421 cannot tightly fit the inner wall of the second drain pipe 25, thereby forming the lower water outlet 260 together with the inner wall of the second drain pipe 25. The liquid flowing in the annular channel 26 will naturally flow downward into the second drain pipe 25 under the action of gravity when passing through the lower water outlet 260, thereby flushing the second drain pipe 25. Further, a plurality of notches 2421 can be arranged on the circumferential edge of the second flange 242, thereby forming a plurality of lower water outlets 260 in the circumferential direction of the annular channel 26.

[0060] In one embodiment of the present disclosure, referring to Figure 4 and Figure 5 , a third flange 243 higher than the first flange 241 in the height direction is further arranged on the outer wall of the first drain pipe 24 and / or the inner wall of the second drain pipe 25, and the first flange 241, the third flange 243, the outer wall of the first drain pipe 24, and the inner wall of the second drain pipe 25 enclose an annular sealing space. In the present embodiment, the third flange 243 is arranged on the outer wall of the first drain pipe 24 and is configured to extend in the radial direction to tightly fit the inner wall of the second drain pipe 25, thereby participating in the enclosure of the annular sealing space. As shown in Figure 4 , a sealing ring 247 is arranged in the annular sealing space, and the inner side and the outer side of the sealing ring 247 tightly fit the outer wall of the first drain pipe 24 and the inner wall of the second drain pipe 25, respectively, thereby sealing the top of the second drain pipe 25.

[0061] In another embodiment, as shown in Figure 7 , the drain channel 21 can be a channel formed by a drain pipe extending vertically and tapering from top to bottom, i.e., the diameter of the drain pipe gradually decreases from the communication port 212 to the drain port 211. The annular channel 26 circumferentially surrounds the outer side of the drain pipe.

[0062] In one embodiment of the present disclosure, referring to Figure 5 and Figure 6 , the annular channel 26 includes a first channel 261 and a second channel 262 in communication with the first channel 261 and lower than the first channel 261 in the height direction, and the first channel 261 and the second channel 262 are configured to enclose the annular channel 26. Specifically, the first flange 241 can be configured to extend in the horizontal direction, while different positions of the second flange 242 differ in the height direction, referring to Figure 5The second flange 242 on the left side of the view direction has a higher height, and thus cooperates with the first flange 241 to form a higher first channel 261; the second flange 242 on the right side has a lower height, and thus cooperates with the first flange 241 to form a lower second channel 262. Since the top wall of the annular channel 26 (i.e. the bottom surface of the first flange 241) has a constant height, the first channel 261 has a smaller diameter than the second channel 262.

[0063] The flushing pipe 23 is configured to communicate with the second channel 262, i.e. the position of the annular channel 26 that is relatively lower and has a relatively larger diameter. The number of the water outlets 260 provided on the second channel 262 is less than that on the first channel 261. After the liquid from the flushing pipe 23 enters the second channel 262, due to the faster flow rate, most of the water flow will flow into the first channel 261 and then spread to the entire annular channel, and only a small part of the water flow will directly flow into the second drain pipe 25 from the water outlet 260 in the second channel 262. In this way, the liquid in the annular channel 26 is homogenized, and the liquid can flow into the second drain pipe 25 from all directions, thereby achieving comprehensive flushing of the second drain pipe 25.

[0064] In an embodiment of the present disclosure, a closing mechanism is provided at the bottom of the first drain pipe 24, which includes at least one valve plate 244 hinged on the first drain pipe 24, and the valve plate 244 is configured to close the opening of the first drain pipe 24 in a natural state and move away from the opening under an external force. Specifically, the present disclosure can be provided with two symmetrically arranged valve plates 244, which together close the lower opening of the first drain pipe 24 in a natural state. When the liquid from the drain sump 11 enters the first drain pipe 24 from the communication port 212, the liquid can push the two valve plates 244 to rotate, so as to open the lower opening of the first drain pipe 24, thereby enabling the liquid to continue to flow downward.

[0065] Further, a counterweight part 245 is provided at the end of the valve plate 244 away from the opening, which is configured to drive the valve plate 244 to close the opening under the action of its own gravity in a natural state. In the case of providing two valve plates 244, the counterweight part 245 can also be correspondingly provided with two. The counterweight part 245 and the valve plate 244 can be respectively arranged at opposite ends of the hinge point. In a natural state, the weight of the counterweight part 245 is greater than that of the valve plate 244, and thus the end of the valve plate 244 can be upwardly tilted to a position closing the opening of the first drain pipe 24. After the liquid flows into the first drain pipe 24, when the accumulated weight of the liquid on the valve plate 244 is greater than that of the counterweight part 245, the end of the counterweight part 245 can be upwardly tilted, and the valve plate 244 is downwardly rotated to open the lower opening of the first drain pipe 24.

[0066] The present disclosure sets the valve plate 244 to close the opening of the first drain pipe 24 in the natural state, so that the drain passage 21 can only keep unobstructed during the execution of the drain step, and the valve plate 244 can always close the opening of the first drain pipe 24 in the case of no drain, thereby blocking the drain passage 21. In this way, the odor from the drain can be blocked by the valve plate 244, and the odor cannot spread upward, and the cleaning base station will not produce odor after a long period of use, thereby improving the user's experience.

[0067] Embodiment two: straight side drain

[0068] In an embodiment of the present disclosure, referring to Figure 9 and Figure 10 , the communication port 212 is located in the middle region of the base station body 1 to communicate with the docking port 111 of the drain groove 11, and the drain port 211 is located on one side of the base station body 1 deviating from the middle position at the back. Among them, the drain passage 21 includes a communicating reversing section 213 and a straight-through section 214, the reversing section 213 is configured to extend obliquely downward from the communication port 212 to the bottom of the base 20, and the straight-through section 214 is configured to extend vertically from the position connected with the reversing section 213 to the drain port 211. In this embodiment, in the vertical direction, the drain port 211 is located on the side of the base 20 deviating from the communication port 212, so the drain passage 21 includes the obliquely downward extending reversing section 213. The dirt from the drain groove 11 enters the reversing section 213 through the communication port 212, and flows obliquely downward along the reversing section 213 under the action of gravity, and after flowing into the straight-through section 214, the flow direction of the dirt changes to vertical downward, and the dirt is discharged into the drain through the drain port 211. This embodiment sets the drain port 211 on one side of the base station body 1 deviating from the middle position at the back, which can be applied to the case where the drain is arranged at the corner position.

[0069] In addition, the drain mechanism 2 is designed to be detachable, and the drain mechanism 2 is symmetrical about the communication port 212, so that the detachable drain mechanism 2 can be installed on the base station body 1 in two installation directions, the first installation direction is as shown in Figure 9 , 10 , at this time the drain port 211 is located on the right side of the base station (as shown in the perspective view of Figure 9 , Figure 10 ), and the second installation direction is to turn the drain mechanism 2 in Figure 9 , 10 by 180°, so that the drain port 211 is located on the left side of the base station. In this way, the user can flexibly adjust according to the position of the drain in the family and the installation space.

[0070] In addition, the user can also freely choose the pollution discharge mechanism 2 in Embodiment 1 or the pollution discharge mechanism 2 in Embodiment 2 to cooperate with the base station body 1, and only needs to choose or purchase a separate pollution discharge mechanism 2, without the need to replace the entire base station.

[0071] The pollution discharge mechanism 2 of the embodiment can also include a flushing assembly, such as Figure 10 As shown, the flushing assembly includes a water injection valve 22 arranged on the base 20, and at least one flushing pipeline 23 in communication with the water injection valve 22, and the water flow in the flushing pipeline 23 is configured to flow into the pollution discharge channel 21 to flush the pollution discharge channel 21.

[0072] In a specific embodiment of the present disclosure, only one water injection valve 22 can be arranged, and the water injection valve 22 is arranged on the base 20 away from the pollution discharge port 211. Referring to Figure 10 The pollution discharge port 211 is located at the right bottom end of the base 20, and the reversing section 213 extends from the middle to the right side from top to bottom to communicate with the straight-through section 214; and the water injection valve 22 is arranged at the left top end of the base 20, and the flushing pipeline 23 in communication with the water injection valve 22 can extend horizontally from left to right. It can be seen that by arranging the water injection valve 22 on the base 20 away from the pollution discharge port 211, the flushing pipeline 23 and the pollution discharge channel 21 can be distributed on both sides of the pollution discharge mechanism 2, and they will not interfere with each other, thereby optimizing the internal waterway design of the pollution discharge mechanism 2.

[0073] It can be understood that since the reversing section 213 has a part of the pipeline section extending basically in the horizontal direction, it is considered that the reversing section 213 is the most likely position to accumulate dirt in the pollution discharge channel 21. In a specific embodiment of the present disclosure, the flushing pipeline 23 can communicate with the reversing section 213, thereby directly flushing the reversing section 213. Specifically, as shown in Figure 10 The jetting member 231 is arranged in the flushing pipeline 23, and is configured to flow out the pressurized fluid as a pressure source from the jetting outlet thereof towards the extension direction of the flushing pipeline 23. The jetting outlet of the jetting member 231 is directed towards the reversing section 213, and the pressurized fluid can push the dirt in the reversing section 213 to flow faster after entering the reversing section 213, thereby preventing the pollution discharge channel 21 from being blocked, and the user does not need to manually clean the blocked pollution discharge channel 21, effectively reducing the user's use burden.

[0074] Application scenario

[0075] The present disclosure provides a cleaning base station for cooperating with a handheld scrubber to perform cleaning work. When the user finishes cleaning the working surface using the handheld scrubber, the handheld scrubber can be parked on the cleaning base station to perform maintenance work such as charging, self-cleaning, pollution discharge, and cleaning liquid replenishment.

[0076] The cleaning base station comprises a base station body 1 and a sewage discharge mechanism 2, wherein the base station body 1 is configured to support the handheld scrubber. A sewage discharge groove 11 is arranged in the base station body 1, and when the handheld scrubber is parked at the cleaning base station, the dirt in the sewage tank 3 can be discharged into the sewage discharge groove 11 under the action of gravity.

[0077] The bottom of the sewage discharge groove 11 is provided with a docking interface 111, and the sewage discharge mechanism 2 is configured to be installed on the base station body 1 and communicate with the docking interface 111 of the sewage discharge groove 11, so that the dirt in the sewage discharge groove 11 can be discharged into the sewage discharge mechanism 2 through the docking interface 111. The sewage discharge mechanism 2 comprises a sewage discharge port 211 which is open downward and is configured to protrude from the bottom end face of the base station body 1 for docking with an external ground drain, wherein the sewage discharge port 211 is configured to be located in the projection plane of the base station body 1 in the height direction. The sewage discharge port 211 protruding from the bottom end face of the base station body 1 can extend into the ground drain to directly connect with the ground drain.

[0078] The dirt from the sewage tank 3 of the handheld scrubber is first discharged into the sewage discharge groove 11, and then enters the sewage discharge mechanism 2 through the docking interface 111 and is directly discharged into the ground drain through the sewage discharge port 211. In this way, it is not necessary to additionally provide a sewage discharge hose to connect the sewage discharge port 211 with the ground drain, but a direct discharge mode can be used for sewage discharge, thereby fundamentally solving the problem that the sewage discharge hose is easily blocked by dirt after being bent. In addition, the sewage discharge port 211 of the present disclosure is located in the projection plane of the base station body in the height direction, thereby ensuring that the overall floor area of the cleaning base station will not increase due to the arrangement of the sewage discharge mechanism 2, thereby saving the space for installing the cleaning base station and facilitating the user to plan the placement position of the cleaning base station.

Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
