[0065] The present disclosure provides a cleaning system comprising a cleaning device and a base station. The cleaning device may be a handheld floor scrubber, a cleaning robot, or the like. The base station is configured to dock with the cleaning device. The cleaning device comprises a body, a sewage bucket disposed on the body, and a sewage outlet disposed on the sewage bucket. The base station comprises a base and a docking platform disposed on the base. The docking platform is provided with a sewage outlet for docking with the sewage outlet of the sewage bucket. Dirt in the sewage bucket is configured to be discharged through the sewage outlet and the sewage outlet.

[0066] A flushing mechanism is provided on the base, which includes a water spray pipe. The water spray pipe is configured to extend the water spray pipe into the inner cavity of the sewage bucket through the sewage outlet. The water spray pipe is configured to spray liquid toward the inner wall of the sewage bucket through the set water outlet to clean the inner wall of the sewage bucket, thereby eliminating the need for users to manually clean the bucket, thereby improving the user experience.

[0067] In the cleaning system disclosed herein, once the cleaning device is docked with the base station, the sewage outlet on the sewage bucket can be docked with the sewage outlet on the base station, allowing dirt within the sewage bucket to be discharged through the outlet and the sewage outlet. Once the sewage is emptied, the flushing mechanism can move into the outlet and spray liquid onto the inner wall of the sewage bucket through the outlet provided on the water spray pipe, flushing away any remaining dirt or solid waste adhering to the inner wall of the sewage bucket, thereby cleaning the sewage bucket. After cleaning, the sewage is still discharged through the sewage outlet and the sewage outlet.

[0068] The technical solution of the present disclosure will be described in detail below in conjunction with specific structures.

[0069] In some embodiments of the present disclosure, Figure 1As shown, the cleaning system includes a cleaning device 1 and a base station 2. The cleaning device 1 has a body 10, on which is provided a sewage bucket 11 for storing sewage, and the sewage bucket 11 is provided with a sewage outlet 110 for discharging sewage. The body 10 can also be provided with a floor brush assembly 14 and a cleaning liquid bucket 13. The floor brush assembly 14 is used to clean the surface to be cleaned, and the cleaning liquid bucket 13 can provide clean water to the floor brush assembly 14, which is conducive to improving cleaning efficiency. The body 10 can also be provided with an air duct and a fan. The fan can create negative pressure in the air duct, and the sewage generated during the cleaning process is sucked into the sewage bucket 11 through the air duct. The base station 2 is used to dock with the cleaning device 1. The base station 2 includes a base 20, which can support the cleaning device 1. The base station 2 can integrate functions such as charging, cleaning, and drying for the cleaning device 1. The base station 2 also includes a tray connected to the bottom of the base 20, which is used to carry the floor brush assembly of the cleaning device 1.

[0070] like Figure 2 As shown, the base station 2 also includes a docking platform 21 provided on the base 20, and the docking platform 21 is provided on the side of the base 20 close to the tray. The tray, the docking platform 21 and the base 20 can form a step structure. When the cleaning equipment 1 is docked with the base station 2, the sewage bucket 11 cooperates with the docking platform 21. A sewage outlet 210 is provided on the docking platform 21, and the sewage outlet 210 is used to dock with the sewage outlet 110 of the sewage bucket 11, and the sewage outlet 210 is located below the sewage outlet 110. After the sewage outlet 110 of the sewage bucket 11 is opened, the dirt in the sewage bucket 11 can fall into the sewage outlet 210 from the sewage outlet 110 and be discharged into the base station 2.

[0071] In one embodiment of the present disclosure, the side of the cleaning device facing the user is designated as the rear side, and the side away from the user is designated as the front side. The wastewater tank 11 is located at the rear side of the device, while the cleaning liquid tank 13 is located at the front side of the device. The sewage outlet 110 can be located at the bottom of the sewage tank 11. This structural design facilitates docking of the sewage outlet 110 with the base station 2 when the cleaning device 1 is placed behind the base station 2.

[0072] Specifically, when the cleaning device 1 is docked on the base station 2, the sewage bucket 11 is located above the docking platform 21, and the sewage outlet 110 of the sewage bucket 11 docks with the sewage outlet 210 of the docking platform 21. The docking platform 21 can be supported on the bottom of the sewage bucket 11, and the sewage outlet 110 can be set at the bottom of the sewage bucket 11, corresponding to the position of the sewage outlet 210, so as to facilitate emptying the sewage in the sewage bucket 11.

[0073] The bottom end surface of the fuselage 10 is provided with a docking area, which is used to directly dock with the base station 2. Figure 2In one embodiment of the present disclosure, the docking area may include a bottom end surface of a first bearing portion 12. The first bearing portion 12 is used to carry a sewage bucket 11. The bottom end surface of the first bearing portion 12 and the docking platform 21 of the base station 2 are a liquid docking portion, which is a liquid exchange portion between the cleaning device 1 and the base station 2. The cleaning device 1 discharges the liquid in the cleaning device 1 into the base station 2 through the liquid docking portion, and the base station 2 injects the liquid in the base station 2 into the cleaning device 1 through the liquid docking portion. In one embodiment of the present patent, the drainage of the sewage bucket 11 of the cleaning device 1 and the replenishment of the cleaning liquid bucket 13 are both achieved through the liquid docking portion.

[0074] refer to Figure 1 and Figure 13 The sewage bucket 11 has a sewage inlet 112. The sewage inlet 112 and sewage outlet 110 of the sewage bucket are located on the bottom surface of the sewage bucket 11, and the sewage outlet 110 is located behind the sewage inlet 112 and exposed downward from the body 10. With this arrangement, when the cleaning device 1 and the base station 2 are docked, the sewage outlet 110 first docks with the sewage outlet 210 of the base station 2. As the cleaning device 1 falls toward the base station 2, the sewage outlet 110 can extend into the sewage outlet 210 until the cleaning device 1 is completely seated on the base station 2.

[0075] Since the sewage outlet 110 is located at the rear side of the sewage bucket 11 relative to the sewage inlet 112, when the cleaning device 1 is docked with the base station 2, the sewage outlet 112 directly docks with and connects to the sewage outlet 210 of the base station 2. The dirt in the sewage bucket 11 flows into the sewage outlet 210 of the base station 2 under its own weight. There is no need to add a connecting pipe between the sewage outlet 110 and the sewage outlet 210, which simplifies the overall structure of the cleaning system and prevents the accumulation of debris due to the presence of bends in the connecting pipe, thereby ensuring smooth sewage discharge.

[0076] refer to Figure 10 and Figure 11 The first supporting portion 12 is provided with a through-notch 121, and the sewage outlet 110 is configured to pass through the notch 121 and emerge from the bottom of the notch 121. Thus, after the cleaning device 1 is placed on the base station 2, the sewage outlet 110 can extend into the sewage outlet 210 of the base station 2, thereby preventing dirt in the sewage bucket 11 from splashing. The sewage outlet 110 emerging from the bottom of the notch 121 mentioned above means that the sewage outlet 110 extends into the notch 121, remains almost flush with the bottom of the notch 121, and does not extend beyond the bottom of the notch 121.

[0077] In one embodiment of the present invention, the notch 121 not only penetrates the first support portion 12 vertically, but also penetrates the side of the first support portion 12 away from the sewage suction pipe, dividing the first support portion 12 into two parts located on either side of the notch 121. The two parts are connected only at the sewage suction pipe. When the sewage bucket 11 is installed on the first support portion 12, the sewage outlet 110 is located within the notch 121. The outer wall surface of the sewage bucket 11 is flush with the outer side of the two parts of the first support portion 12 divided by the notch 121, and forms part of the rear profile of the fuselage 10. The notch 121 is arranged in this way to facilitate the installation and removal of the sewage bucket 11, and will not be blocked when installing or removing the sewage bucket 11.

[0078] Continue to refer Figure 2 and Figure 12 The cleaning device 1 also includes a cleaning liquid barrel 13. A water inlet 122 is provided on the first bearing portion 12. The water inlet 122 is connected to the liquid discharge port through a pipe. The liquid discharge port of the cleaning liquid barrel 13 discharges the liquid in the cleaning liquid barrel 13 to the floor brush assembly 14 to wet the roller brush of the floor brush assembly or the ground in contact with the floor brush assembly. The water inlet 122 is located on the outside of the sewage outlet 110. Correspondingly, an upper water inlet 211 is provided on the docking platform 21. The upper water inlet 211 is located on the outside of the sewage outlet 210. After the cleaning device 2 is docked with the base station 1, the upper water inlet 211 is docked with the water inlet 122, so that the base station 1 replenishes the cleaning liquid barrel 13 of the cleaning device 1 through the upper water inlet 211 and the water inlet 122. In this way, the liquid exchange between the cleaning device 1 and the base station 2 is realized in one area, which simplifies the structural design and reduces the number of openings on the cleaning liquid barrel 13 and the sewage barrel 11.

[0079] like Figure 1 、 Figure 3 As shown, the base station 2 is also provided with a flushing mechanism 3 for flushing the sewage bucket 11 of the cleaning device 1. The flushing mechanism 3 includes a water spray pipe 31, and the water spray pipe 31 is provided with a water outlet. The water spray pipe 31 can be connected to, for example, a clean water bucket, a cleaning liquid bucket, a tap water pipe, etc., and can provide liquids such as clean water and cleaning liquid to the water spray pipe 31. In one embodiment of the present disclosure, a water storage tank is provided in the base 20, and the water storage tank can be connected to the water spray pipe 31 via a water pump, thereby pumping liquid in the water storage tank, such as clean water or cleaning liquid, into the water spray pipe 31.

[0080] When cleaning device 1 is placed on base station 2, water spray pipe 31 extends into the inner cavity of sewage bucket 11 through the connected sewage outlet 210 and sewage outlet 110. Liquid is sprayed toward the inner wall of sewage bucket 11 through the water outlet to clean the sewage bucket. The flushing mechanism 3 is located on base station 2, which avoids adding weight and structural complexity to cleaning device 1, making it more portable and convenient for users.

[0081] In some embodiments of the present disclosure, Figure 3 、 Figure 4 As shown, the flushing mechanism 3 is arranged on the base 20 of the base station 2, and the water spray pipe 31 can extend upward from the sewage outlet 210 on the docking platform 21, and then extend into the inner cavity of the sewage bucket 11 through the sewage outlet 110 to clean the inner wall of the sewage bucket 11. The water spray pipe 31 is located inside the base 20 in the initial state, and the free end of the water spray pipe 31 is located in the sewage outlet 210 of the docking platform 21. After the sewage bucket 11 is docked with the docking platform 21, the water spray pipe 31 can move toward the sewage bucket 11 and extend into the sewage outlet 110, and the water spray pipe 31 moves at least to extend the water outlet into the inner cavity of the sewage bucket 11. That is, the sewage discharge path and the flushing path of the sewage bucket 11 are the same, and the sewage discharge and flushing of the sewage bucket 11 are both achieved through the sewage outlet 110 and the sewage outlet 210.

[0082] refer to Figure 1 and Figure 14 In some embodiments of the present disclosure, the drain chute assembly 22 includes a drain chamber 220. A through-hole 222 is defined in the sidewall of the drain chamber 220. The free end of the water spray pipe 31 seals against the through-hole 222, forming a storage position for the free end of the water spray pipe 31. When flushing the sewage bucket 11 begins, the free end of the water spray pipe 31 moves from the storage position toward the sewage bucket 11. After flushing is complete, the free end of the water spray pipe 31 retracts to the storage position, sealing the through-hole 222.

[0083] Combine Figure 4 and Figure 14 , the central axis of the sewage outlet 110 is parallel to or coincides with the axis of the free end of the water spray pipe 31, the free end of the water spray pipe 31 is in front of the center position of the sewage outlet 110, and the sewage trough assembly 22 adjacent to the water spray pipe 31 is provided with an outwardly extending flange 221, the flange 221 is along the upper end of the side wall of the sewage cavity 120, and extends from the position corresponding to the sewage outlet 210 to the opposite sides of the sewage outlet 210, and the sewage outlet 210 extends from the position corresponding to the sewage cavity 120 to the position corresponding to the flange 221. A through hole 222 is provided on the flange 221 at a position corresponding to the sewage outlet 210, and the free end of the water spray pipe 31 moves from the flange 221 through the through hole 222 toward the sewage bucket 11. After the flushing is completed, the water spray pipe 31 retracts to the position of the flange 221. On the one hand, the structure is more compact, and on the other hand, this design can reduce the residual dirt in dead corners during the sewage discharge process. In one embodiment of the present disclosure, Figure 3 、 Figure 4As shown, when the sewage bucket 11 is mated with the docking platform 21, the extension direction of the sewage bucket 11 aligns with the extension and movement directions of the water spray pipe 31, allowing the water spray pipe 31 to smoothly extend into the sewage bucket 11 through the sewage outlet 110. Specifically, when the sewage bucket 11 is mated with the docking platform 21, the extension direction is vertical, and the extension direction of the sewage bucket 11 can deviate from the height by a certain angle. The extension and movement directions of the water spray pipe 31 align with the extension direction of the sewage bucket 11 at this time, thereby ensuring that the water spray pipe 31 can smoothly extend into the sewage bucket 11. The docking platform 21 is perpendicular to the extension direction of the sewage bucket 11, thereby providing at least vertical support for the sewage bucket 11.

[0084] In one embodiment of the present disclosure, Figure 4 、 Figure 5 As shown, a drain chute assembly 22 is provided on the base 20 of the base station 2, and the drain chute assembly 22 forms a sewage outlet 210 on the docking platform 21. The drain chute assembly 22 is configured so that when the cleaning device 1 is docked on the base station 2, it can dock with the sewage outlet 110 of the sewage bucket 11. The drain chute assembly 22 is positioned lower than the sewage outlet 110, and the sewage in the sewage bucket 11 can flow to the drain chute assembly 22 through the sewage outlet 110 and the sewage outlet 210 under the action of gravity.

[0085] Specifically, the sewage outlet 210 of the sewage chute assembly 22 can be open upward and its size is not smaller than the sewage outlet 110. The downward projection of the sewage outlet 110 completely falls into the inlet of the sewage chute assembly 22, so that sewage can completely enter the inlet of the sewage chute assembly 22. When the cleaning device 1 is docked on the base station 2, the sewage outlet 110 of the sewage bucket 11 can extend into the sewage outlet 210 of the docking platform 21.

[0086] In one embodiment of the present disclosure, the water spray pipe 31 is constructed to pass through the sewage trough assembly 22 and extend into the inner cavity of the sewage bucket 11 through the sewage outlet 110, thereby making the structure of the water spray pipe 31 and the sewage trough assembly 22 more compact.

[0087] In one embodiment of the present disclosure, the discharge outlet of the drain chute assembly 22 is provided on the rear side of the base 20; the dirt flowing into the drain chute assembly 22 is configured to be discharged through the discharge outlet. In detail, the discharge outlet of the drain chute assembly 22 can be connected to a drainage channel such as a floor drain. When the discharge outlet of the drain chute assembly 22 is connected to the floor drain, the sewage in the sewage bucket 11 can be directly discharged into the floor drain through the drain chute assembly 22, without the need for the user to manually dump the sewage bucket 11, thereby improving the user experience. Alternatively, the discharge outlet of the drain chute assembly 22 can also be connected to a sewage collecting bucket, which can be provided inside the base 20 or separately provided outside the base station 2.

[0088] In one embodiment of the present disclosure, Figure 4 As shown, a sealing assembly 111 is provided on the drain outlet 110 of the sewage bucket 11. The sealing assembly 111 is used to open or close the sewage bucket 11. When the sealing assembly 111 opens the drain outlet 110, the sewage in the sewage bucket 11 can be discharged through the drain outlet 110 and enter the sewage trough assembly 22. The water spray pipe 31 can then extend into the inner cavity of the sewage bucket 11 through the drain outlet 110. During the cleaning process of the cleaning device 1, the sealing assembly 111 closes the drain outlet 110, thereby preventing sewage from leaking from the drain outlet 110 and preventing the drain outlet 110 from causing a loss of negative pressure in the sewage bucket 11, which would affect the cleaning effect.

[0089] In one embodiment of the present disclosure, the sealing component 111 is controlled by a motor, and the sealing component 111 can be a valve structure or a gate structure. The sealing component 111 can be controlled to open and close automatically by the motor. The cleaning device 1 is placed on the base station 2. When sewage needs to be discharged or the sewage bucket 11 needs to be flushed, the motor can be controlled to open the sealing component 111, and the sewage in the sewage bucket 11 is discharged through the sewage outlet 110 under the action of gravity. Afterwards, the water spray pipe 31 can be extended into the inner cavity of the sewage bucket 11 through the sewage outlet 110 to flush the inner cavity of the sewage bucket 11. The sewage after flushing will be discharged through the sewage outlet 110 under the action of gravity, thereby completing the cleaning of the sewage bucket 11.

[0090] In another embodiment of the present disclosure, Figure 4 、 Figure 5 As shown, the sealing assembly 111 is controlled by a trigger mechanism 23 to open or close the sewage outlet 110. The trigger mechanism 23 is provided on the base station 2. After the cleaning device 1 is docked with the base station 2, the trigger mechanism 23 is configured to move to open the sealing assembly 111 to allow the dirt in the sewage bucket 11 to flow out through the sewage outlet 110, and to move to close the sealing assembly 111 to close the sewage outlet 110.

[0091] Specifically, one end of the sealing assembly 111 is hingedly connected to one side of the drain outlet 110, and the other end is a free end. This free end engages with the other side of the drain outlet 110 via an elastic buckle to close the drain outlet 110. The trigger mechanism 23 can be driven by a motor to open the buckle, allowing the sealing assembly 111 to rotate downward about the hinged end under the action of gravity or an elastic device, thereby opening the drain outlet 110. The trigger mechanism 23 can also be driven by the motor to push the sealing assembly 111 to rotate upward about the hinged end, causing the free end of the sealing assembly 111 to engage with the buckle, thereby closing the drain outlet 110.

[0092] In one embodiment of the present disclosure, Figure 4As shown, when the water spray pipe 31 extends into the interior of the sewage bucket 11, a gap is left between it and the drain outlet 110. Liquid sprayed onto the inner wall of the sewage bucket 11 is configured to flow through the drain outlet 110 and the sewage outlet 210 to the drain chute assembly 22 under the action of gravity. When the water spray pipe 31 extends out of the sewage outlet 210, a gap is also left between it and the sewage outlet 210, allowing dirt within the sewage bucket 11 to enter the drain chute assembly 22 through the sewage outlet 210. During the flushing process of the sewage bucket 11, the liquid sprayed from the water spray pipe 31 promptly flows through the gap between the water spray pipe 31 and the drain outlet 110 to the drain chute assembly 22, and does not remain in the sewage bucket 11.

[0093] In one embodiment of the present disclosure, the water spray pipe 31 is configured to spray liquid onto the inner wall of the sewage bucket 11 through the water outlet when moving within the inner cavity of the sewage bucket 11. The water spray pipe 31 has a certain range of movement after extending into the inner cavity of the sewage bucket 11. During the movement of the water spray pipe 31, the water outlet can spray water onto a wider range of the inner wall of the sewage bucket 11, thereby increasing the cleaning range. Specifically, the water spray pipe 31 can move along the axis of the sewage bucket 11 within the inner cavity of the sewage bucket 11, and during the movement, it sprays water onto the inner wall of the sewage bucket 11 through the water outlet, ensuring that the inner wall of the sewage bucket 11 at all positions can be flushed, thereby improving the flushing effect of the sewage bucket 11.

[0094] In one embodiment of the present disclosure, at least one water outlet is provided on the water spray pipe 31. If there are multiple water outlets, they may be distributed around the circumference of the water spray pipe 31 and / or at least along the axial direction of the water spray pipe 31, thereby spraying water onto a wider area of ​​the inner wall of the sewage bucket 11 and increasing the cleaning range. Of course, the multiple water outlets may also be distributed on the water spray pipe 31 in other regular or irregular patterns.

[0095] In one embodiment of the present disclosure, Figure 4 、 Figure 5 As shown, a nozzle assembly 32 can be installed on the free end of the water spray pipe 31, and the water outlet is set on the nozzle assembly 32. The nozzle assembly 32 can increase the pressure of the liquid when it is sprayed, thereby improving the cleaning effect on the inner wall of the sewage bucket 11.

[0096] In a specific embodiment of the present disclosure, the nozzle assembly 32 can be configured to be rotatably connected to the water spray pipe 31, and can be configured to rotate around the axis of the water spray pipe 31 under the action of water pressure to spray water in all directions, so that the cleaning range can more comprehensively cover the inner wall of the sewage bucket 11.

[0097] In a specific embodiment of the present disclosure, Figure 6 、 Figure 7As shown, the spray head assembly 32 includes a mounting seat 321 connected to the free end of the water spray pipe 31. The mounting seat 321 has a valve chamber 320. The spray head assembly 32 also includes a valve core 322 movably connected to the valve chamber 320. The valve chamber 320 is in communication with the water spray pipe 31, forming an outlet channel for water to flow out. The water outlet is the open end 3201 of the valve chamber 320. The water flow in the water spray pipe 31 can be sprayed out through the open end 3201 of the valve chamber 320. The valve core 322 is configured to move along the axial direction of the spray head assembly 32 to open or close the valve chamber 320.

[0098] In detail, the end of the valve core 322 can be fitted into the open end 3201 of the valve cavity 320, thereby closing the valve cavity 320. The end of the valve core 322 can move outward to leave the open end 3201 of the valve cavity 320, thereby opening the valve cavity 320, and the water in the valve cavity 320 is ejected through the open end 3201.

[0099] In a specific embodiment of the present disclosure, Figure 6 、 Figure 7 As shown, the valve core 322 is disposed in the valve chamber 320 via an elastic device 323. The elastic device 323 acts to close the valve chamber 320, and the valve core 322, under the action of water pressure, overcomes the force of the elastic device 323 and moves to open the valve chamber 320. The elastic device 323 can be a spring, a spring, or the like, and its elastic action drives the valve core 322 to close the valve chamber 320. As waste in the sewage bucket 11 flows through the sewage outlet 210 to the sewage chute assembly 22, the valve core 322, under the action of the elastic device 323, closes the valve chamber 320, preventing waste from entering the valve chamber 320.

[0100] The opening and closing of the nozzle assembly 32 is controlled by the water pressure in the water spray pipe 31. For example, when the water pump that provides liquid to the water spray pipe 31 is turned on, the nozzle assembly 32 is opened under the action of the water pressure, and the nozzle assembly 32 is closed after the water pump is turned off.

[0101] Specifically, the valve chamber 320 includes a mounting portion 3202. The elastic device 323, which is a spring, is mounted in the mounting portion 3202. One end of the valve core 322 is mounted in the mounting portion 3202, and the other end of the valve core 322 extends into the open end 3201 of the valve chamber 320. One end of the spring engages with the valve core 322, while the other end engages in the mounting portion 3202, pre-pressing the valve core 322 in the valve chamber 320. When the water pressure in the valve chamber 320 increases, it pushes the valve core 322 to overcome the elastic force of the spring, allowing the valve core 322 to open the open end 3201 of the valve chamber 320.

[0102] like Figure 6 、 Figure 7As shown, a sealing ring can be set between the side wall of the valve core 322 and the inner wall of the installation part 3202. The valve core 322 can slide relative to the sealing ring. The sealing ring can prevent the liquid in the valve cavity 320 from entering the installation part 3202, thereby preventing the elastic device 323 from contacting water.

[0103] In a specific embodiment of the present disclosure, Figure 6 、 Figure 7 As shown, the mounting seat 321 includes a radially extending extension portion 3211, which is located below the valve cavity 320. The extension portion 3211 is provided with at least one water inlet 3212 connecting the valve cavity 320 and the water spray pipe 31. The water in the water spray pipe 31 can enter the valve cavity 320 through the water inlet 3212. The opening direction of the water inlet 3212 is configured to be inclined.

[0104] In such Figure 8 In one embodiment shown, the water inlet 3212 extends obliquely relative to the extension direction of the mounting base 321, or spirally around the extension direction of the valve core 322. The water inlet 3212 can guide the water flow. After entering the valve cavity 320 through the water inlet 3212, the water flow rotates within the valve cavity 320 and is then ejected in a rotational manner through the open end 3201 of the valve cavity 320 to flush the inner wall of the sewage bucket 11.

[0105] In detail, the valve chamber 320 also includes an intermediate chamber 3203 located between the open end 3201 and the mounting portion 3202. The water inlet 3212 is connected to the intermediate chamber 3203. Water flows into the intermediate chamber 3203 from the water inlet 3212 and rotates in the intermediate chamber 3203. When the open end 3201 is opened, the rotating water flow is ejected through the open end 3201.

[0106] In a specific embodiment of the present disclosure, Figure 7 、 Figure 8 As shown, the open end 3201 of the valve cavity 320 has a frustoconical flared structure, and the end of the valve core 322 is constructed with a tapered end 3221 that matches the shape of the open end 3201 of the valve cavity 320. The tapered end 3221 has a conical structure. When the valve core 322 is pushed open by water pressure, the tapered end 3221 of the valve core 322 moves outward, forming an annular gap between the valve core 322 and the inner wall of the open end 3201 of the valve cavity 320. The rotating water in the valve cavity 320 is ejected along the annular gap and, guided by the tapered end 3221, the water flows in all directions, thereby increasing the flushing range.

[0107] In detail, the opening end 3201 of the valve cavity 320 gradually narrows towards the middle cavity 3203, and the connection between the opening end 3201 and the middle cavity 3203 is narrow. When the water flow in the middle cavity 3203 enters the opening end 3201, the flow rate increases, which is beneficial to increase the force of the water flow to flush the inner wall of the sewage bucket 11 and increase the cleaning effect.

[0108] In some embodiments of the present disclosure, the mounting base 321 can be fixedly connected to the water spray pipe 31 by threaded connection, interference fit, bonding, fastener connection, etc. Figure 7 、 Figure 8 As shown, the mounting base 321 includes a first end and a second end of different diameters. The outer surface of the mounting base 321 forms a stepped shaft structure, with the first end having a larger diameter than the second end. The outer wall of the first end is threaded and is threadedly connected to the free end of the water spray pipe 31. A sealing ring may be provided between the first end and the water spray pipe 31. The open end 3201 and the intermediate cavity 3203 of the valve chamber 320 are located within the first end, while the mounting portion 3202 is located within the second end. A water inlet 3212 is provided at the junction of the first and second ends.

[0109] In one embodiment of the present disclosure, the water spray pipe 31 can be configured as a telescopic pipe structure, through which the water spray pipe 31 can be extended into the interior of the sewage bucket 11, or retracted. Specifically, when the water spray pipe 31 is extended, it extends into the interior of the sewage bucket 11 through the sewage outlet 110. When the water spray pipe 31 is retracted, it exits the interior of the sewage bucket 11 through the sewage outlet 110. The water spray pipe 31 can adopt a structure comprising at least two pipe sections connected in a sleeve, a telescopic bellows, or other conventional telescopic pipe structures, and the present disclosure does not impose specific limitations on this.

[0110] In one embodiment of the present disclosure, Figure 4 As shown, a guide groove 24 is provided in the base 20, and the water spray pipe 31 is configured to cooperate with the guide groove 24. A motion mechanism 34 can also be provided in the base 20, and the motion mechanism 34 is configured to drive the water spray pipe 31 to move relative to the guide groove 24, so as to extend into the inner cavity of the sewage bucket 11, or retract.

[0111] In detail, such as Figure 5 As shown, the base 20 may be provided with a housing chamber 201 for accommodating the movement mechanism 34. The housing chamber 201 is separated from the drain chute assembly 22, and the water spray pipe 31 can move along the guide groove 24 into the housing chamber 201. A sealing structure may be provided between the housing chamber 201 and the drain chute assembly 22 to prevent sewage in the drain chute assembly 22 from entering the housing chamber 201.

[0112] In some embodiments of the present disclosure, Figure 4As shown, the water spray pipe 31 engages with the guide groove 24 via a linear bearing 25, allowing the water spray pipe 31 to slide along the linear bearing 25. The other end of the water spray pipe 31, opposite the nozzle assembly 32, is connected to a water supply hose via a pipe joint. The hose can follow the water spray pipe 31 within the base 20. A sealing sleeve 26 is also provided at one end of the guide groove 24, adjacent to the sewage outlet 210, and is sleeved onto the outside of the water spray pipe 31. The sealing sleeve 26 is configured to form a sliding seal with the water spray pipe 31. The provision of the sealing sleeve 26 prevents dirt entering the sewage outlet 210 from entering the guide groove 24.

[0113] The motion mechanism 34 may include a driving device such as a motor, a cylinder, a hydraulic cylinder, an electric push rod, etc. to provide power. The driving device can directly cooperate with the water spray pipe 31 to drive the water spray pipe 31 to extend and retract, or the driving device can cooperate with the water spray pipe 31 through a transmission mechanism such as a gear assembly, a screw nut, etc. to drive the water spray pipe 31 to extend and retract through the transmission mechanism.

[0114] In one embodiment of the present disclosure, the motion mechanism 34 includes an electric push rod, the output end of which is fixedly connected to the water spray pipe 31 and drives the water spray pipe 31 to move telescopically along the length direction of the water spray pipe 31.

[0115] In another embodiment of the present disclosure, Figure 9 As shown, the motion mechanism 34 includes a transmission belt 343 and a drive structure that drives the transmission belt 343 to rotate. The transmission belt 343 is fixed to the water spray pipe 31 and is configured to drive the water spray pipe 31 to extend or retract. Specifically, the drive structure of the motion mechanism 34 includes a driving pulley 341 and a driven pulley 342, with the transmission belt 343 connected between the driving pulley 341 and the driven pulley 342. It also includes a drive motor 344 that drives the driving pulley 341 to rotate. The drive motor 344 drives the transmission belt 343 in forward and reverse directions, thereby causing the water spray pipe 31 to extend or retract.

[0116] The above-mentioned structure of the motion mechanism 34 is only an example, and other structures that can drive the water spray pipe 31 to extend and retract fall within the protection scope of the present disclosure.

[0117] In one embodiment of the present disclosure, the cleaning system further includes a control unit, which can be provided on the cleaning device 1 or the base station 2, or can be provided remotely. The control unit is in communication with the trigger mechanism 23 and the motion mechanism 34 on the base station 2. The trigger mechanism 23 is controlled by the control unit to control the sealing assembly 111 to open or close the sewage outlet 110, and the motion mechanism 34 is controlled by the control unit to drive the water spray pipe 31 to extend and retract. A valve for opening or closing the water spray pipe 31 can also be provided on the base station 2. The opening and closing of the valve is controlled by the control unit. When the valve is opened, the water spray pipe 31 can spray water.

[0118] The cleaning device 1 is placed on the base station 2. The control unit can control the trigger mechanism 23 to open the sealing component 111 on the sewage outlet 110 based on the self-cleaning command, and control the motion mechanism 34 to drive the water spray pipe 31 to extend into the inner cavity of the sewage bucket 11 to spray water, thereby realizing automatic emptying and cleaning of the sewage bucket 11, saving the user's workload, making it more convenient to use, and improving the user experience.

[0119] In some embodiments of the present disclosure, the water spray pipe 31 has a first position extending into the inner cavity of the sewage bucket 11, a second position when retracted into the base 2, and a third position between the first and second positions. The first position refers to the position where the water spray pipe 31 moves to the top dead center, that is, the water spray pipe 31 moves upward to the maximum stroke position, at which time the top end of the water spray pipe 31 is located at the top of the sewage bucket 11. For example, referring to Figure 5 In the viewing direction, the water spray pipe 31 is at the top dead center. At this position, the water spray pipe 31 cannot extend further upward. The second position refers to the position where the water spray pipe 31 moves to the bottom dead center. At this position, the water spray pipe 31 cannot retract further downward. At this time, the top end of the water spray pipe 31 retracts into the sewage outlet 210 and is lower than the top edge of the sewage outlet 210. By setting the top dead center and the bottom dead center, the water spray pipe 31 can be prevented from moving too much and colliding with the structure of the sewage bucket 11 or the base 2, thereby avoiding damage to the water spray pipe 31, the sewage bucket 11 or the base 2.

[0120] The water spray pipe 31 also has a third position disposed between the first position and the second position. The third position is a position located a certain distance above the second position. For example, the third position may be 5 mm higher than the second position. In one embodiment of the present disclosure, when the water spray pipe 31 is in the third position, the top end of the water spray pipe 31 is still lower than the top edge of the sewage outlet 210.

[0121] In one embodiment of the present application, when the water spray pipe 31 is in the second position, the top surface of the water spray pipe 31 remains flush with the wall surface of the sewage chamber 220. In other words, the top surface of the water spray pipe 31 constitutes a part of the wall surface of the sewage chamber 220.

[0122] refer to Figure 16A first detection element 271 and a second detection element 272 are provided in the base. The first detection element 271 is configured to be triggered when the water spray pipe 31 moves to the first position. A triggering portion for triggering the first detection element 271 and the second detection element 272 can be provided on the water spray pipe 31. The triggering portion can be a flange structure or a tactile rod structure. The position of the first detection element 271 in the base is such that when the water spray pipe 31 moves to the first position, the first detection element 271 is triggered to send a control signal. The control signal is sent to the control unit and can be used as a signal indicating that the water spray pipe 31 has reached the first position. Based on the control signal, the control unit can control the water spray pipe 31 to stop moving or perform other corresponding controls to prevent it from continuing to extend and causing damage to the base station 2.

[0123] The position of the second detection element 272 within the base 2 is such that when the water spray pipe 31 moves to the second position, the second detection element 272 is triggered to send a control signal. When the second detection element 272 is triggered, a signal indicating that the water spray pipe 31 has reached the second position can be sent to the control unit. Based on the signal, the control unit can control the water spray pipe 31 to stop moving or perform other corresponding controls. The first detection element 271 and the second detection element 272 disclosed in the present invention can be switches for detecting travel, such as micro switches and limit switches, or other types of switches familiar to those skilled in the art, and are not limited to this.

[0124] In one embodiment of the present disclosure, the control unit is configured to control the water spray pipe 31 to move in the opposite direction to the third position for docking based on the electrical signal of the second detection element that is triggered when the water spray pipe 31 moves to the second position. In an embodiment of the present disclosure, after the water spray pipe 31 is cleaned in the sewage bucket 11, it needs to be retracted into the base 2. At this time, the control unit controls the water spray pipe 31 to move from the first position to the second position. After the water spray pipe 31 moves to the second position and triggers the second detection element 272, the control unit can control the water spray pipe 31 to move in the opposite direction to the third position for docking based on the electrical signal triggered by the second detection element 272. That is, the water spray pipe 31 will move in the direction of the first position until it moves to the third position for docking.

[0125] This is because the second position of the present invention is the trigger position of the second detection element 272. When using a switch that relies on pressure to trigger, such as a micro switch or a limit switch, if the above switch is in a compressed state for a long time, it may cause the switch to fail. Therefore, the water spray pipe 31 needs to be docked at a third position higher than the second position to protect the second detection element 272.

[0126] refer to Figure 17 , the first position is recorded as A, the second position is recorded as B, and the third position is recorded as C. Figure 17At the position indicated by D1 in the figure, when the water spray pipe 31 moves to point B, the second detection element 272 triggers an electrical signal indicating that the water spray pipe 31 has moved to the second position. Referring to the position indicated by D2, the control unit controls the water spray pipe 31 to move in the opposite direction to point C based on the electrical signal triggered by the second detection element 272, so that the bottom of the water spray pipe 31 is clear of the second detection element 272. As a result, the second detection element 272 remains in the deactivated state.

[0127] In the cleaning system of the present disclosure, the water spray pipe 31 is always docked in the third position C. In some embodiments of the present disclosure, before the trigger mechanism 23 opens the sealing assembly 111, the control unit is configured to control the water spray pipe 31 to move from the third position to the second position. Thereafter, the second detection element 272 triggers an electrical signal for the water spray pipe 31 to move to the second position. Based on the electrical signal from the second detection element 272, the control unit controls the water spray pipe 31 to remain in the second position. This application scenario involves the process in which the trigger mechanism 23 needs to open the sealing assembly 111 to drain sewage from the sewage bucket 11. Because the water spray pipe 31 moves upward a predetermined distance relative to the second position to reach the third position, dirt in the sewage bucket 11 may adhere to or entangle the top area of ​​the water spray pipe 31. Therefore, during the process of opening the sealing assembly 111 to drain sewage, the water spray pipe 31 needs to be lowered and moved to the second position. During this process, when the water spray pipe 31 moves to the second position and triggers the second detection element 272, the electrical signal triggered by the second detection element 272 serves as a control signal to stop the water spray pipe 31.

[0128] After the sewage in the sewage bucket 11 is completely discharged, the inner cavity of the sewage bucket 11 needs to be cleaned. Figure 17 In some embodiments of the present disclosure, the control unit is configured to control the water spray pipe 31 to move from the second position to the first position based on the cleaning instruction to spray liquid onto the inner wall of the sewage bucket 11. For example, referring to Figure 17 At the schematic positions D1 to D3 in FIG, the top end of the water spray pipe 31 begins to move from the second position B to the first position A. At this point, the first detection element 271 is triggered and emits an electrical signal indicating that the water spray pipe 31 has reached the cleaning start position. Based on the electrical signal emitted by the first detection element 271, the control unit controls the water spray pipe 31 to begin spraying water. During the water spraying process, the control unit can control the reciprocating motion of the water spray pipe 31 within the interior of the sewage bucket 11 based on time or other parameters to completely clean the sewage bucket 11.

[0129] When the sewage bucket is cleaned, the water spray pipe 31 moves from the first position A to the second position B. After the second detection element 272 is triggered, the control unit controls the water spray pipe 31 to move in the opposite direction to the third position C based on the triggered electrical signal and stays at the third position C.

[0130] The present disclosure also provides a base station for placing cleaning equipment, which can be a handheld floor scrubber, a cleaning robot, etc. The base station includes a base 20 and a docking platform 21 provided on the base 20. The docking platform 21 is provided with a sewage outlet 210 for docking with the sewage outlet 110 of the cleaning equipment 1. A flushing mechanism 3 is provided on the base 20, and the flushing mechanism 3 includes a water spray pipe 31; the flushing mechanism 3 is configured to be able to extend the water spray pipe 31 into the sewage bucket 11 of the cleaning equipment 1 through the sewage outlet 110; the liquid in the water spray pipe 31 is configured to be sprayed toward the inner wall of the sewage bucket 11 through the water outlet provided on the water spray pipe 31, thereby cleaning the inner wall of the sewage bucket 11, eliminating the need for the user to manually clean the sewage bucket 11, thereby improving the user experience. The specific structure and principle of the base station can be referred to the above-mentioned cleaning system, and therefore, it will not be repeated in this disclosure.

[0131] The present disclosure also provides a control method for a cleaning system, which uses the above-mentioned cleaning system and includes the following steps:

[0132] Step 1: Place the cleaning device 1 on the base station 2 , and dock the sewage outlet 110 of the sewage bucket 11 in the cleaning device 1 with the sewage outlet 210 on the docking platform 21 .

[0133] After the cleaning device 1 has been operating for a period of time, its sewage bucket 11 absorbs sewage. The cleaning device 1 can be docked on the base station 2 for drainage. The bottom of the sewage bucket 11 has a sewage outlet 110, which is closed by a sealing assembly 111. The docking platform 21 of the base 20 docks with the bottom of the sewage bucket 11, and the sewage outlet 110 docks with the sewage outlet 210 on the docking platform 21. The trigger mechanism 23 on the base 20 can control the sealing assembly 111 to open or close the sewage outlet 110. After the sealing assembly 111 is opened, the dirt in the inner cavity of the sewage bucket 11 can be discharged through the sewage outlet 110 and the sewage outlet 210 into the sewage trough assembly 22 of the base 20.

[0134] Step 2: Control the water spray pipe 31 in the flushing mechanism 3 to extend into the inner cavity of the sewage bucket 11 through the sewage outlet 210 and the sewage outlet 110.

[0135] The flushing mechanism 3 is disposed within the base 20 and includes a water spray pipe 31 and a motion mechanism 34 for driving the water spray pipe 31 to extend or retract. When the cleaning device 1 is docked with the base 2, the water spray pipe 31 is located below the sewage outlet 110. The motion mechanism 34 drives the water spray pipe 31 upward, allowing the water spray pipe 31 to extend out of the sewage outlet 210 and then enter the inner cavity of the sewage bucket 11 through the sewage outlet 110 docked with the sewage outlet 210.

[0136] Step three: control the water spray pipe 31 to spray water toward the inner wall of the sewage bucket 11 to clean the inner wall of the sewage bucket 11 .

[0137] The water spray pipe 31 is connected to a hose for water supply. The water outlet of the water spray pipe 31 is located at one end extending into the sewage bucket 11, and can spray water into the sewage bucket 11. A nozzle assembly 32 is provided at the water outlet. The valve core 322 of the nozzle assembly 32 is closed by the action of a spring, preventing dirt discharged from the sewage bucket through the sewage outlet 110 and the sewage outlet 210 from entering the nozzle assembly 32. The valve core 322 of the nozzle assembly 32 can be opened by water pressure, spraying water onto the inner wall of the sewage bucket 11, thereby rinsing away dirt attached to the inner wall of the sewage bucket 11. The cleaned liquid can enter the sewage outlet 210 through the gap between the sewage outlet 110 and the water spray pipe 31.

[0138] Specifically, the control method described above is implemented by the cleaning system's control unit. When the cleaning device 1 is placed on the base station 2, the control unit, based on a self-cleaning command, controls the trigger mechanism 23 on the base 20 to open the sealing assembly 111 on the drain outlet 110, allowing sewage in the sewage bucket 11 to enter the sewage trough assembly 22 through the drain outlet 110 and the sewage outlet 210. The control unit then controls the motion mechanism 34 to extend the water spray pipe 31, allowing it to extend through the sewage outlet 210 and the drain outlet 110 into the interior of the sewage bucket 11. The control unit then controls the valve of the water spray pipe 31 to open, allowing the water spray pipe 31 to spray water through the nozzle assembly 32 onto the inner wall of the sewage bucket 11 for flushing. After a predetermined cleaning time, the control unit controls the valve of the water spray pipe 31 to close, stopping the water spraying, and controls the motion mechanism 34 to retract the water spray pipe 31. The control unit then controls the trigger mechanism 23 to close the sealing assembly 111 on the drain outlet 110, completing the self-cleaning process.

[0139] A self-cleaning button may be provided on the cleaning device 1 or the base station 2, and the user may issue a self-cleaning instruction to the control unit by pressing the self-cleaning button. Alternatively, the user may issue a self-cleaning instruction to the control unit via a mobile client, a remote control device, or the like.

[0140] The following describes the technical solution adopted by the present disclosure in conjunction with specific application scenarios to facilitate understanding. In the following application scenarios, the cleaning equipment is a floor scrubber and the base station is a floor scrubber base station as an example.

[0141] Application Scenario 1

[0142] When a user uses a floor scrubber to clean the floor, the wastewater generated during the cleaning process is sucked into the wastewater bucket 11 of the floor scrubber and stored. After cleaning, the floor scrubber is placed on the floor scrubber base station. The base 20 of the floor scrubber base station supports the floor scrubber. The wastewater bucket 11 of the floor scrubber is matched with the docking platform 21 on the base 20, and the sewage outlet 110 on the sewage bucket 11 is docked with the sewage outlet 210 on the docking platform 21.

[0143] The user can issue a self-cleaning command to the control unit by pressing the self-cleaning button. Based on the self-cleaning command, the control unit controls the trigger mechanism 23 to open the sealing assembly 111 on the sewage outlet 110. Sewage in the sewage bucket 11 flows through the sewage outlet 110 and the sewage outlet 210 into the sewage trough assembly 22, and then discharges into the floor drain through the sewage trough assembly 22. The control unit controls the motion mechanism 34 to extend the water spray pipe 31 upward and into the interior of the sewage bucket 11 through the sewage outlet 210 and the sewage outlet 110. The water pump supplying water to the water spray pipe 31 is turned on. The nozzle assembly 32 on the water spray pipe 31 opens under the action of the water pressure, and water is sprayed in a rotating manner toward the inner wall of the sewage bucket 11 to clean it. The water used to clean the inner wall of the sewage bucket 11 can flow through the gap between the water spray pipe 31 and the sewage outlet 110 into the sewage outlet 210 and into the sewage trough assembly 22.

[0144] After the predetermined cleaning time, the control unit controls the water pump to turn off, the water pressure decreases, and the nozzle assembly 32 can be closed under the action of the spring. The control unit controls the motion mechanism 34 to retract the water spray pipe 31 and leave the sewage bucket 11, and then controls the trigger mechanism 23 to make the sealing assembly 111 close the sewage outlet 110 of the sewage bucket 11.

[0145] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
