Furthermore, the lowered and forward shift of the center of gravity also allows the cleaning brush head to adhere more closely to the surface to be cleaned, thereby improving the cleaning capability of the cleaning device.

[0051] In addition, conductive components can be set on the periphery of the brush head body, which facilitates electrical connection with the transmission head set on the base station, eliminating the need for electrical connection on the top of the base station and saving height space of the base station.

[0078] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0079] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0080] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0081] like Figure 1 As shown, some embodiments provide a cleaning system. This cleaning system may include a base station 20 and a cleaning device 10. The base station 20 can be used to house the cleaning device 10. The cleaning device 10 may be a floor scrubber, a robotic vacuum cleaner, a vacuum and mop combo, etc., and this disclosure does not impose specific limitations thereon.

[0082] like Figures 1 to 9 As shown, the base station 20 may include a body 201 and a transmission component 202. The body 201 may include a base 2011. The top of the base 2011 may have a placement space 2013, which can be used to place the cleaning device 10.

[0083] The main body 201 may also include a stop structure 2012, which may be located on top of the seat 2011, and the seat 2011 may be connected to the stop structure 2012. The seat 2011 and the stop structure 2012 may form the aforementioned placement space 2013.

[0084] In some embodiments, the stop structure 2012 can guide the cleaning device 10 during placement on the base station 20, ensuring that the cleaning device 10 can accurately enter the placement space 2013 and thus accurately dock with the base station 20. Furthermore, the stop structure 2012 can also limit the cleaning device 10 after it has been placed on the base station 20, preventing it from falling off.

[0085] There may be one or more stop structures 2012. When the body part 201 includes a stop structure 2012, the stop structure 2012 may be provided on either side of the seat 2011 to guide and limit the cleaning device 10 on that side.

[0086] When the main body 201 includes a plurality of stop structures 2012, the plurality of stop structures 2012 can be spaced apart, thereby improving its ability to guide and limit the cleaning equipment 10. For example, the main body 201 may include a first stop structure 2014 and a second stop structure 2015, which can be spaced apart.

[0087] However, it is not limited to this. When the main body 201 includes multiple stop structures 2012, any two adjacent stop structures 2012 can be connected to each other so that each stop structure 2012 is connected as one unit, thereby improving the structural strength and limiting effect of each stop structure 2012.

[0088] Furthermore, when the main body 201 includes a plurality of stop structures 2012, the plurality of stop structures 2012 may be located on different sides of the seat 2011, for example: the first stop structure 2014 and the second stop structure 2015 may be located on opposite sides of the seat 2011.

[0089] like Figures 2 to 9 As shown, the transmission component 202 may include a transmission head 2021 and a mounting base 2022. The transmission head 2021 can be mounted on the mounting base 2022, and the transmission head 2021 can be used to transmit electrical energy and / or transmit electrical signals to the cleaning device 10. That is, it can be understood that the transmission head 2021 can be used to transmit electrical energy to the cleaning device 10 to charge the cleaning device 10. Alternatively, the transmission head 2021 can be used to transmit electrical signals to the cleaning device 10 for information interaction with the cleaning device 10. Alternatively, the transmission head 2021 can be used to both transmit electrical energy and transmit electrical signals to the cleaning device 10, so as to simultaneously satisfy the functions of charging the cleaning device 10 and interacting with the cleaning device 10.

[0090] The mounting base 2022 can be installed on the side of the main body 201 near the placement space 2013, thereby saving height space of the base station 20 and reducing its thickness. Furthermore, since the transmission head 2021 is mounted on the mounting base 2022, when the mounting base 2022 is installed on the side of the main body 201 near the placement space 2013, the main body 201 can provide protection for both the transmission head 2021 and the mounting base 2022, preventing damage from external impacts.

[0091] Furthermore, the mounting base 2022 can be installed on the side of the stop structure 2012 near the placement space 2013. Alternatively, the mounting base 2022 can be installed on the side of the base body 2011 near the placement space 2013. Alternatively, the mounting base 2022 can be installed on both the side of the stop structure 2012 near the placement space 2013 and the side of the base body 2011 near the placement space 2013. This arrangement can further save height space in the base station 20 and further reduce its thickness.

[0092] The mounting base 2022 may have a first initial position and a first avoidance position, the first avoidance position being farther away from the placement space 2013 relative to the first initial position. During the process of placing the cleaning device 10 in the placement space 2013, the mounting base 2022 can switch from the first initial position to the first avoidance position, allowing the mounting base 2022 to move away from the placement space 2013. This avoids hard contact between the mounting base 2022 and the cleaning device 10, reducing the probability of damage to both the mounting base 2022 and the cleaning device 10, and improving the service life and operational stability of the base station 20.

[0093] Meanwhile, when the mounting base 2022 switches from the first initial position to the first avoidance position, the mounting base 2022 can drive the transmission head 2021 to move away from the placement space 2013, which can also prevent the transmission head 2021 from making hard contact with the cleaning equipment 10, thereby slowing down the wear rate of the transmission head 2021, improving the docking effect between the base station 20 and the cleaning equipment 10, and ensuring the stability of the transmission head 2021 in transmitting power and / or transmitting electrical signals, thereby further improving the service life and operational stability of the base station 20.

[0094] In some embodiments, the mounting base 2022 may also have a first working position. When the mounting base 2022 is in the first working position, the transmission head 2021 may be electrically connected to the cleaning device 10 to deliver electrical energy and / or electrical signals to the cleaning device 10.

[0095] The first working position can be close to the placement space 2013 relative to the first clearance position. That is, the first working position can be located between the first clearance position and the first initial position, or the first working position can be the first initial position. After the cleaning device 10 is placed in the placement space 2013, the mounting base 2022 can switch from the first clearance position to the first working position. That is, it can be understood that when the cleaning device 10 is placed in the placement space 2013, the mounting base 2022 can move towards the placement space 2013, so that the mounting base 2022 switches to the first working position, thereby enabling the transmission head 2021 to abut against the electrical connection structure on the cleaning device 10, so that the transmission head 2021 can stably transmit electrical energy and / or electrical signals to the cleaning device 10.

[0096] like Figure 5As shown, the transmission component 202 may further include a first moving element 2023. The first moving element 2023 may be configured to switch the mounting base 2022 from a first clearance position to a first working position. Furthermore, when the first working position is between the first initial position and the first clearance position, the first moving element 2023 may also be configured to switch the mounting base 2022 from the first working position to the first initial position, so that after the cleaning device 10 is detached from the placement space 2013, the mounting base 2022 can be reset, thereby ensuring that the next docking can proceed normally.

[0097] The first moving component 2023 can be a first elastic element. The first elastic element can be a spring, but is not limited to this; it can also be made of soft rubber, etc. The first elastic element can be disposed between the mounting base 2022 and the stop structure 2012. When the mounting base 2022 is in the first clearance position, the first elastic element can have a restoring force, thereby allowing the first elastic element to drive the mounting base 2022 to switch to the first working position, or the first elastic element to drive the mounting base 2022 to switch to the first initial position. This configuration ensures that the first moving component 2023 can drive the mounting base 2022 to move while reducing the manufacturing cost of the first moving component 2023.

[0098] like Figure 5 and Figure 6 As shown, the transmission component 202 may further include a first guide structure 2024. The first guide structure 2024 may be disposed on the stop structure 2012, or on the mounting base 2022, or both the mounting base 2022 and the stop structure 2012 may have the first guide structure 2024. Furthermore, the first guide structure 2024 can be used to provide guidance for the mounting base 2022 when switching positions, to ensure that the mounting base 2022 can move accurately along a predetermined direction.

[0099] The first guide structure 2024 can be set on the side of the stop structure 2012 near the placement space 2013 to avoid occupying other space of the stop structure 2012. It can also prevent the first guide structure 2024 from interfering with the cleaning device 10 during the process of placing the cleaning device 10 in the placement space 2013 and after the cleaning device 10 is placed in the placement space 2013 when it is set in other positions of the stop structure 2012.

[0100] However, it is not limited to this. The first guide structure 2024 can also be set in other positions of the stop structure 2012. It can be selected and set according to the actual situation, and all of this is within the protection scope of this disclosure.

[0101] The first guide structure 2024 can be a first guide post, and the first elastic element can be sleeved on the outer circumferential surface of the first guide post to limit the first elastic element by the first guide post, so as to prevent the first elastic element from shifting position or falling off when the mounting base 2022 switches positions, thereby improving the stability of the mounting base 2022 when switching positions and improving the service life of the base station 20.

[0102] Two first elastic elements and two first guide posts can be provided. The two first guide posts can be diagonally arranged on the side of the stop structure 2012 near the placement space 2013, and the two first elastic elements can be respectively sleeved on the outer circumferential surface of the two first guide posts. This arrangement can improve the accuracy and stability of the movement of the mounting base 2022 when switching positions. At the same time, setting only two first guide posts and two first elastic elements diagonally can avoid the problem of jamming of the mounting base 2022 due to excessive limitation during movement caused by too many first guide posts and first elastic elements, thus ensuring the smoothness of the mounting base 2022 switching positions.

[0103] Alternatively, the first guide structure 2024 can also be disposed on the side of the mounting base 2022 facing away from the placement space 2013, to avoid the first guide structure 2024 occupying the circumferential space of the mounting base 2022, facilitating the placement of other structural components around the mounting base 2022. Furthermore, it can also prevent positional interference between the first guide structure 2024 and the cleaning equipment 10 during or after placement in the placement space 2013 if the first guide structure 2024 is disposed in other positions on the mounting base 2022.

[0104] However, it is not limited to this. The first guide structure 2024 can also be set on the periphery of the mounting base 2022. It can be selected and set according to the actual situation, which is within the protection scope of this disclosure.

[0105] When the first guide wire structure is positioned on the side of the mounting base 2022 facing away from the placement space 2013, the two first guide posts can be diagonally positioned on the same side of the mounting base 2022 facing away from the placement space 2013, and the two first elastic elements can be respectively fitted onto the outer circumferential surfaces of the two first guide posts. This arrangement improves the accuracy and stability of the movement of the mounting base 2022 when switching positions. Furthermore, by only positioning the two first guide posts and two first elastic elements diagonally, the problem of jamming due to excessive number of first guide posts and first elastic elements during movement is avoided, ensuring smooth position switching of the mounting base 2022.

[0106] The first guide post can be a cross-shaped guide post, which can reduce manufacturing costs while ensuring high structural strength. However, it is not limited to this; the first guide post can also be cylindrical, prismatic, etc., and can be selected and set according to the actual situation.

[0107] The first guide structure 2024 may also be a non-first guide post. For example, the first guide structure 2024 may be a guide groove or a guide block, which is also within the protection scope of this disclosure.

[0108] In some embodiments, the first moving member 2023 may be an active driving member. For example, the first moving member 2023 may include a driving part and a connecting part. The connecting part may be connected to the mounting base 2022, and the driving part may drive the connecting part to move in a direction closer to or further away from the placement space 2013, so that the connecting part may drive the mounting base 2022 to switch from a first clearance position to a first working position, and may drive the mounting base 2022 to switch from the first working position to a first initial position.

[0109] When the first moving component 2023 is an active driving component, the first moving component 2023 can also be configured to switch the mounting base 2022 from the first initial position to the first avoidance position. That is, when the cleaning device 10 is placed in the placement space 2013, the first moving component 2023 can actively drive the mounting base 2022 from the first initial position to the first avoidance position to avoid the cleaning device 10.

[0110] In other embodiments, the first working position can be a first avoidance position, that is, when the mounting base 2022 reaches the first avoidance position, the transmission head 2021 can be electrically connected to the cleaning device 10, which is also within the protection scope of this disclosure.

[0111] In some embodiments, such as Figures 2 to 5 As shown, the transmission component 202 may further include a guide wheel 2025. That is, both the first transmission component 203 and the second transmission component 204 may include a guide wheel 2025. The guide wheel 2025 is rotatably mounted on the mounting base 2022, and the guide wheel 2025 may be configured to provide guidance for the cleaning device 10 during placement in the placement space 2013.

[0112] The maximum distance between the guide wheel 2025 and the mounting base 2022 in the first direction X can be greater than the maximum distance between the transmission head 2021 and the mounting base 2022 in the first direction X. Here, the first direction X can be the direction of movement of the mounting base 2022 when switching positions. That is, the guide wheel 2025 protrudes from the transmission head 2021. With this configuration, during the placement of the cleaning device 10 in the placement space 2013, the guide wheel 2025 can support the cleaning device 10, preventing contact between the cleaning device 10 and the transmission head 2021, thereby avoiding wear and tear on the transmission head 2021.

[0113] like Figure 4 As shown, the guide wheel 2025 may include a first guide surface 2026 and a second guide surface 2027. The second guide surface 2027 may be disposed on the side of the first guide surface 2026 away from the base body 2011, that is, when the base station 20 is placed on the ground, the second guide surface 2027 may be disposed above the first guide surface 2026. The second guide surface 2027 may be inclined in a direction close to the axis of the guide wheel 2025, that is, it can be understood that the second guide surface 2027 may be a conical surface or a partially conical surface. With this configuration, the second guide surface 2027 can be used to guide the cleaning device 10 when it is placed vertically into the placement space 2013 or when it is taken out vertically from the placement space 2013, thereby improving the smoothness of the placement and removal of the cleaning device 10.

[0114] The first guide surface 2026 and / or the second guide surface 2027 can be made of soft rubber. This design can prevent the first guide surface 2026 and / or the second guide surface 2027 from wearing down the cleaning device 10. However, it is not limited to this; the first guide surface 2026 and / or the second guide surface 2027 can also be made of other softer materials, such as foam, which can be selected and set according to the actual situation.

[0115] In some embodiments, the projections of the guide wheel 2025 along its axial extension direction and the projection of the transmission head 2021 along the axial extension direction of the guide wheel 2025 may at least overlap. This arrangement reduces the horizontal distance between the guide wheel 2025 and the transmission head 2021, saving space in the mounting base 2022 and improving the integration of the transmission assembly 202. The axial extension direction of the guide wheel 2025 may intersect the horizontal direction. For example, the angle between the axial extension direction of the guide wheel 2025 and the horizontal direction may be 90°, etc.

[0116] The horizontal projections of the guide wheel 2025 and the transmission head 2021 can at least overlap. This arrangement reduces the vertical distance between the guide wheel 2025 and the transmission head 2021, saving space in the mounting base 2022 and improving the integration of the transmission assembly 202.

[0117] The projections of the guide wheel 2025 along its axial extension direction and the transmission head 2021 along the axial extension direction of the guide wheel 2025 can at least overlap, and the projections of the guide wheel 2025 and the transmission head 2021 in the horizontal direction can also at least overlap. This arrangement further reduces the distance between the guide wheel 2025 and the transmission head 2021, further saves space in the mounting base 2022, and further improves the integration of the transmission assembly 202.

[0118] In some embodiments, such as Figures 7 to 9 As shown, the mounting base 2022 may include a first plate portion 20221 and a second plate portion 20224. The first plate portion 20221 may have a first through hole. The second plate portion 20224 and the first plate portion 20221 may be disposed opposite to each other, and the second plate portion 20224 may be located away from the placement space 2013 relative to the first plate portion 20221. The transmission head 2021 may be mounted on the second plate portion 20224, and at least a portion of the transmission head 2021 may protrude through the first through hole for electrical connection with the cleaning device 10.

[0119] The transmission head 2021 may have a second initial position and a second avoidance position, the second avoidance position being farther away from the placement space 2013 relative to the second initial position. During the placement of the cleaning device 10 into the placement space 2013, the transmission head 2021 can switch from the second initial position to the second avoidance position. That is, during the placement of the cleaning device 10 into the placement space 2013, the transmission head 2021 can move away from the placement space 2013, thereby avoiding hard contact between the transmission head 2021 and the cleaning device 10, reducing the degree of wear on the transmission head 2021, and further improving the service life and operational stability of the base station 20.

[0120] In some embodiments, the transmission head 2021 may also have a second operating position. When the transmission head 2021 is in the second operating position, the transmission head 2021 may be electrically connected to the cleaning device 10 to deliver electrical energy and / or electrical signals to the cleaning device 10.

[0121] The second working position can be close to the placement space 2013 relative to the second clearance position. That is, the second working position can be located between the second clearance position and the second initial position, or the second working position can be the second initial position. After the cleaning device 10 is placed in the placement space 2013, the transmission head 2021 can switch from the second clearance position to the second working position. That is, it can be understood that when the cleaning device 10 is placed in the placement space 2013, the transmission head 2021 can move towards the placement space 2013, so that the transmission head 2021 switches to the second working position, thereby enabling the transmission head 2021 to abut against the electrical connection structure on the cleaning device 10, so that the transmission head 2021 can stably transmit electrical energy and / or electrical signals to the cleaning device 10.

[0122] like Figure 8 As shown, the transmission component 202 may further include a second moving member 2028. The second moving member 2028 may be configured to switch the transmission head 2021 from a second clearance position to a second working position. Furthermore, when the second working position is between the second initial position and the second clearance position, the second moving member 2028 may also be configured to switch the transmission head 2021 from the second working position to the second initial position, so that after the cleaning device 10 is detached from the placement space 2013, the transmission head 2021 can be reset, thereby ensuring that the next docking can proceed normally.

[0123] The second moving component 2028 can be a second elastic element. The second elastic element can be a spring, but is not limited to this; it can also be made of soft rubber, etc. The second elastic element can be disposed between the transmission head 2021 and the second plate portion 20224. When the transmission head 2021 is in the second clearance position, the second elastic element can have a restoring force, thereby allowing the second elastic element to drive the transmission head 2021 to switch to the second working position, or the second elastic element to drive the transmission head 2021 to switch to the second initial position. This configuration ensures that the second moving component 2028 can drive the transmission head 2021 while reducing the manufacturing cost of the second moving component 2028.

[0124] like Figure 8 and Figure 9 As shown, the transmission component 202 may further include a second guide structure 2029. The second guide structure 2029 may be disposed on the second plate portion 20224, and the second guide structure 2029 may be used to provide guidance for the transmission head 2021 when the transmission head 2021 switches positions, so as to ensure that the transmission head 2021 can move accurately along a predetermined direction.

[0125] The second guide structure 2029 can be a second guide post, and the second elastic element can be sleeved on the outer circumferential surface of the second guide post to limit the second elastic element by the second guide post, so as to prevent the second elastic element from shifting position or falling off when the transmission head 2021 switches positions, thereby improving the stability of the transmission head 2021 switching positions and improving the service life of the base station 20.

[0126] The second guide post can be a cross-shaped guide post, which can reduce manufacturing costs while ensuring high structural strength. However, it is not limited to this; the second guide post can also be cylindrical, prismatic, etc., and can be selected and set according to the actual situation.

[0127] The second guide structure 2029 may also be a non-second guide post. For example, the second guide structure 2029 may be a guide groove or a guide block, which is also within the protection scope of this disclosure.

[0128] In some embodiments, the second moving member 2028 can be an active driving member. For example, the second moving member 2028 may include a driving part and a connecting part. The connecting part may be connected to the transmission head 2021, and the driving part may drive the connecting part to move in a direction closer to or farther from the placement space 2013, so that the connecting part may drive the transmission head 2021 to switch from a second avoidance position to a second working position, and may drive the transmission head 2021 to switch from the second working position to a second initial position.

[0129] When the second moving member 2028 is an active driving member, the second moving member 2028 can also be configured to switch the transmission head 2021 from the second initial position to the second avoidance position. That is, when the cleaning device 10 is placed in the placement space 2013, the second moving member 2028 can actively drive the transmission head 2021 from the second initial position to the second avoidance position to avoid the cleaning device 10.

[0130] In other embodiments, the second working position can be a second avoidance position, that is, the transmission head 2021 can be electrically connected to the cleaning device 10 when it reaches the second avoidance position, which is also within the protection scope of this disclosure.

[0131] In some embodiments, such as Figure 4 and Figure 8As shown, the first plate portion 20221 may have a third guide surface 20222. The third guide surface 20222 may be disposed on the side of the first plate portion 20221 near the placement space 2013 and may surround at least part of the first through hole. The third guide surface 20222 may be inclined toward the axis of the first through hole, and the third guide surface 20222 is not on the movement path of the transmission head 2021. With this configuration, the third guide surface 20222 can guide the cleaning device 10 during the placement of the cleaning device 10 in the placement space 2013, preventing the cleaning device 10 from colliding with the transmission head 2021 and damaging the transmission head 2021. At the same time, the third guide surface 20222 can guide the electrical connection of the cleaning device 10 to the transmission head 2021, ensuring that the cleaning device 10 can be accurately electrically connected to the transmission head 2021.

[0132] The third guide surface 20222 can be arranged around the first through hole, so that the third guide surface 20222 is a partially conical surface. With this arrangement, when the cleaning device 10 is placed in the placement space 2013 from any direction, the third guide surface 20222 can guide the cleaning device 10.

[0133] The first plate portion 20221 may also have a fourth guide surface 20223, which may extend along the axial direction of the first through hole and connect the first plate portion 20221 and the end of the third guide surface 20222 away from the first plate portion 20221, so as to improve the guidance of the movement of the transmission head 2021 and further improve the accuracy of the movement of the transmission head 2021.

[0134] Furthermore, the outer peripheral surface of the transmission head 2021 can contact the fourth guide surface 20223. This arrangement can further improve the guiding capability of the fourth guide surface 20223 for the transmission head 2021.

[0135] In some embodiments, there may be a gap between the first plate portion 20221 and the second plate portion 20224. This arrangement provides sufficient movement space for the transmission head 2021. The first gap 20225 may be less than or equal to 6 mm to avoid the problem of excessive thickness of the mounting base 2022 due to an excessively large first gap 20225, and at the same time, it can also reduce the movement stroke of the transmission head 2021 during movement.

[0136] The transmission head 2021 may include a main body 20211 and a stop 20212. At least a portion of the main body 20211 can extend through a first through-hole for electrical connection with the cleaning device 10. The stop 20212 can be connected to the main body 20211, and at least a portion of the stop 20212 is located between a first plate 20221 and a second plate 20224 to limit the main body 20211, preventing it from falling out of the first through-hole during movement, thereby further improving the service life and operational stability of the base station 20.

[0137] In some embodiments, such as Figure 2 and Figure 3 As shown, base station 20 may include: a first transmission component 203 and a second transmission component 204. The first transmission component 203 may include a first mounting base 2031 and a first transmission head 2032. The second transmission component 204 may be disposed at a distance from the first transmission component 203, and the second transmission component 204 may include a second mounting base 2041 and a second transmission head 2042.

[0138] The polarities of the first transmission head 2032 and the second transmission head 2042 can be opposite, meaning that both the first transmission head 2032 and the second transmission head 2042 can be used to transmit electrical energy, and the first transmission head 2032 and the second transmission head 2042 can be the first positive terminal and the first negative terminal, respectively. This configuration allows for a larger gap between the positive and negative terminals of the base station 20, preventing short circuits.

[0139] In addition, the first transmission head 2032 and the second transmission head 2042 can also be used to transmit electrical energy and electrical signals, respectively. That is, one of the first transmission head 2032 and the second transmission head 2042 can be an electrode, and the other can be a signal transmission end. By arranging the first transmission component 203 and the second transmission component 204 at intervals, the distance between the electrode and the signal transmission end can be increased, avoiding the problem of short circuits between the electrode and the signal transmission end.

[0140] The first transmission component 203 can be disposed on the first stop structure 2014, and the second transmission component 204 can be disposed on the second stop structure 2015. That is, the first mounting base 2031 can be mounted on the side of the first stop structure 2014 near the placement space 2013, and the second mounting base 2041 can be mounted on the side of the second stop structure 2015 near the placement space 2013. Since the first stop structure 2014 and the second stop structure 2015 are spaced apart, the distance between the first transmission component 203 and the second transmission component 204 can be further increased, further reducing the probability of short circuit.

[0141] Furthermore, when the first stop structure 2014 and the second stop structure 2015 are located on opposite sides of the base 2011, the first transmission component 203 can be further moved away from the second transmission component 204, further reducing the risk of a short circuit between the first transmission head 2032 and the second transmission head 2042.

[0142] In some embodiments, the first transmission head 2032 can be a first positive electrode, and the second transmission head 2042 can be a first negative electrode. The distance between the first transmission head 2032 and the upper surface of the base 2011 can be greater than the distance between the second transmission head 2042 and the upper surface of the base 2011. The upper surface of the base 2011 can be the surface on which the cleaning device 10 is placed after being placed in the placement space 2013, and which supports the cleaning device 10. That is, the first transmission head 2032 is positioned higher than the second transmission head 2042. This configuration avoids the problem of a short circuit between the first transmission head 2032 and the second transmission head 2042 due to water conduction on the base station 20. Furthermore, since the first positive electrode is generally connected to an external power supply and the first negative electrode is generally grounded, a short circuit will only occur when the water level on the base station 20 is above the first transmission head 2032, thereby further reducing the probability of a short circuit at the first positive electrode.

[0143] The distance between the first transmission head 2032 and the upper surface of the base 2011 can be greater than or equal to 30mm and less than or equal to 70mm. For example, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This setting ensures that the first transmission head 2032 has sufficient height to reduce the probability of a short circuit. Simultaneously, it avoids the problem of needing to increase the height of the first stop structure 2014 due to the first transmission head 2032 being set too high, thus reducing the overall height of the base station 20.

[0144] The distance between the second transmission head 2042 and the upper surface of the base 2011 can be greater than or equal to 20mm and less than or equal to 40mm. For example, 20mm, 25mm, 30mm, 35mm, 40mm, etc. This setting avoids the second transmission head 2042 being too low and too close to the base 2011, thus reducing the probability of short circuits between the second transmission head 2042 and components on the base 2011. Simultaneously, it avoids the problem of the first transmission head 2032 needing to be set too high due to the second transmission head 2042 being set too high, which allows for a reduction in the height of the first stop structure 2014 and the second stop structure 2015, thereby reducing the overall height of the base station 20.

[0145] In some embodiments, the second transmission component 204 may further include a third transmission head 2043. The third transmission head 2043 can be mounted on the second mounting base 2041, that is, the third transmission head 2043 and the second transmission head 2042 can be mounted on the same mounting base 2022. The third transmission head 2043 can be used to transmit electrical signals. Since the second transmission head 2042 is the first negative terminal, placing the third transmission head 2043 and the second transmission head 2042, which transmit electrical signals, on the same mounting base 2022 will not cause a short circuit risk. At the same time, placing the third transmission head 2043 and the second transmission head 2042 on the same mounting base 2022 can improve the integration of the base station 20 and save space in the transmission component 202.

[0146] like Figure 4 As shown, the second transmission head 2042 may have a first center line L1 extending vertically, and the third transmission head 2043 may have a second center line L2 extending vertically. The first center line L1 and the second center line L2 may be staggered in the horizontal direction. This arrangement can prevent accidental contact during the horizontal placement of the cleaning device 10 in the placement space 2013, which could lead to problems with signal communication and power supply mis-triggers.

[0147] The second transmission head 2042 may have a third center line L3 extending horizontally, and the third transmission head 2043 may have a fourth center line L4 extending horizontally. The third center line L3 and the fourth center line L4 may be staggered in the vertical direction. This arrangement can prevent accidental contact during the vertical placement of the cleaning device 10 in the placement space 2013, which could lead to problems with signal communication and power supply mis-triggers.

[0148] The distance between the third transmission head 2043 and the upper surface of the base 2011 can be greater than the distance between the second transmission head 2042 and the upper surface of the base 2011. That is, the third transmission head 2043 is positioned higher than the second transmission head 2042. This configuration avoids the problem of a short circuit between the third transmission head 2043 and the second transmission head 2042 due to water conduction on the base station 20. Furthermore, since the third transmission head 2043, which transmits electrical signals, is connected to an electrical signal source, and its first negative terminal is generally grounded, a short circuit will only occur when the water level on the base station 20 is above the third transmission head 2043, further reducing the probability of a short circuit in the third transmission head 2043.

[0149] The distance between the third transmission head 2043 and the upper surface of the base 2011 can be greater than or equal to 40mm and less than or equal to 70mm. For example, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, etc. This setting ensures that the third transmission head 2043 has sufficient height to reduce the probability of short circuits. Simultaneously, it avoids the problem of needing to increase the height of the second stop structure 2015 due to the third transmission head 2043 being set too high, thus reducing the overall height of the base station 20.

[0150] In some embodiments, such as Figure 1 , Figures 10 to 13 As shown, the cleaning device 10 may include a cleaning brush head 101 and a conductive element 102. The cleaning brush head 101 can be used to clean the surface to be cleaned, and the conductive element 102 can be configured to transmit electrical energy and / or electrical signals. When the cleaning brush head 101 is placed in the placement space 2013, the conductive element 102 can dock with the corresponding structure of the base station 20. For example, the conductive element 102 can be electrically connected to the transmission head 2021 to receive electrical energy and / or electrical signals transmitted by the transmission head 2021 and transmit the electrical energy and / or electrical signals to the components inside the cleaning device 10. For example, the cleaning device 10 may include a battery and power-consuming components, and the conductive element 102 can transmit the electrical energy transmitted by the transmission head 2021 to the battery and power-consuming components. The cleaning device 10 may also include a signal processor. The conductive element 102 can transmit the electrical signal delivered by the transmission head 2021 to the signal processor, or the conductive element 102 can transmit the electrical signal emitted by the signal processor to the transmission head 2021, and the transmission head 2021 can transmit the electrical signal to the processor in the base station 20. In this way, the base station 20 and the cleaning device 10 can achieve signal interaction. The shape of the conductive element 102 can be rectangular, but it is not limited thereto. The shape of the conductive element 102 can also be circular, triangular, etc., and this disclosure does not impose specific limitations on it.

[0151] The cleaning brush head 101 may include a brush head body 1011 and a liquid reservoir 1012. The brush head body 1011 can be used to clean the surface to be cleaned. The liquid reservoir 1012 can be used to store cleaning fluid and / or detergent to improve the cleaning effect of the cleaning brush head 101. The cleaning fluid and / or detergent stored in the liquid reservoir 1012 can also be used to clean the brush head body 1011. However, it is not limited to this; the liquid reservoir 1012 can also be used to store wastewater, which is also within the scope of this disclosure.

[0152] The liquid storage tank 1012 can be connected to the brush head body 1011. This configuration allows the center of gravity of the cleaning device 10 to be lowered and moved forward, increasing the active driving force of the cleaning device 10, enabling it to be pushed into or move into the placement space 2013 of the base station 20. Furthermore, the lowered and forward-moving center of gravity of the cleaning device 10 also allows the cleaning brush head 101 to fit more tightly against the surface to be cleaned, thereby improving the cleaning ability of the cleaning device 10.

[0153] Furthermore, the liquid reservoir 1012 can be detachably mounted on the top surface of the brush head body 1011. It is understood that the top surface of the brush head body 1011 refers to the side of the brush head body 1011 that is furthest from the surface to be cleaned during the cleaning process of the cleaning device 10. This arrangement further lowers and shifts the center of gravity of the cleaning device 10, thereby increasing the active driving force of the cleaning device 10. Moreover, with the center of gravity further lowered and shifted forward, the cleaning brush head 101 can fit more tightly against the surface to be cleaned, thus further improving the cleaning ability of the cleaning device 10. Additionally, by mounting the liquid reservoir 1012 on the top surface of the brush head body 1011, it is also convenient to remove and install the liquid reservoir 1012 when the cleaning device 10 is placed on the base.

[0154] The conductive element 102 can be disposed on the circumferential side of the brush head body 1011 to facilitate electrical connection with the transmission head 2021 disposed on the base station 20, eliminating the need for electrical connection on the top of the base station 20 and saving height space of the brush head body 1011. It should be noted that the circumferential side of the brush head body 1011 refers to the front, rear, left, and right sides of the brush head body 1011, with the forward direction of the cleaning device 10 as the front. The forward direction of the cleaning device 10 refers to the direction of movement of the cleaning device 10 during the cleaning process of the surface to be cleaned.

[0155] The conductive element 102 can be located on at least one side of the brush head body 1011 in the second direction Y. Specifically, in the horizontal plane, the second direction Y is perpendicular to the forward direction of the cleaning device 10. It should be noted that, assuming the surface to be cleaned is flat, the horizontal plane can be parallel to the surface. This arrangement avoids the conductive element 102 occupying space in front of and behind the brush head body 1011, thus preventing it from affecting the cleaning operation of the brush head body 1011.

[0156] In some embodiments, a receiving groove 10111 may be provided on the circumferential side of the brush head body 1011, and the conductive element 102 may be disposed on the bottom surface of the receiving groove 10111. This arrangement provides a more stable mounting space for the conductive element 102 using the receiving groove 10111, and the sidewalls of the receiving groove 10111 protect the conductive element 102. Furthermore, when the conductive element 102 abuts against the transmission head 2021, the sidewalls of the receiving groove 10111 can limit the transmission head 2021, preventing the conductive element 102 from disengaging from the transmission head 2021 during electrical connection, thus ensuring the stability of power and / or signal transmission.

[0157] The sidewall of the receiving groove 10111 can be inclined in a direction away from the center line extending along its depth direction of the receiving groove 10111. With this configuration, the sidewall of the receiving groove 10111 can be used to guide the transmission head 2021, so as to ensure that the transmission head 2021 can accurately enter the receiving groove 10111 and make electrical connection with the conductive element 102.

[0158] The depth of the receiving groove 10111 can be less than or equal to 3mm, such as 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. This setting can avoid the receiving groove 10111 from being too deep, thus saving the space occupied by the receiving groove 10111.

[0159] The width of the receiving groove 10111 can be greater than or equal to 5mm and less than or equal to 30mm. For example: 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. This setting ensures that the receiving groove 10111 has sufficient width to accommodate the conductive component 102, and avoids the problem of excessive space occupied by the receiving groove 10111 due to its excessive width.

[0160] In some embodiments, the cleaning device 10 may further include a cleaning working section 106 and a traveling section 107. The cleaning working section 106 may be disposed on the brush head body 1011 for cleaning the surface to be cleaned. The cleaning working section 106 may be a roller brush, side brush, etc. The traveling section 107 may be disposed on the brush head body 1011, and the traveling section 107 and the cleaning working section 106 may be spaced apart in the forward direction of the cleaning device 10.

[0161] The aforementioned conductive element 102 can be disposed between the cleaning work section 106 and the traveling section 107 to avoid the conductive element 102 occupying the installation space of the cleaning work section 106 or the traveling section 107. In the forward direction of the cleaning device 10, the distance between the conductive element 102 and the cleaning work section 106 can be greater than the distance between the conductive element 102 and the traveling section 107. This arrangement keeps the conductive element 102 away from the cleaning work section 106, preventing dirt on the surface to be cleaned or dirt rolled up by the cleaning work section 106 from contaminating the conductive element 102, thus avoiding short circuits or poor contact problems with the conductive element 102.

[0162] Furthermore, the conductive element 102 can be disposed on the side of the brush head body 1011 near the walking part 107. This arrangement can further increase the distance between the conductive element 102 and the cleaning working part 106, further preventing dirt on the surface to be cleaned or dirt rolled up by the cleaning working part 106 from contaminating the conductive element 102, and thus further preventing short circuits or poor contact problems of the conductive element 102.

[0163] In some embodiments, the brush head body 1011 may also be provided with a clearance space 10112, which may be disposed on the same side as the conductive element 102. This clearance space 10112 may be located close to the walking portion 107 relative to the conductive element 102. This clearance space 10112 may be used to avoid protruding structures on the base station 20, so that after the cleaning device 10 is placed on the base station 20, the protruding structure can be located within the clearance space 10112, thus preventing the protruding structure from obstructing the electrical connection between the conductive element 102 and the transmission head 2021. The protruding structure may be the aforementioned guide wheel 2025, but is not limited to it; it may also be other protruding structures on the base station 20.

[0164] Furthermore, the brush head body 1011 may be provided with a clearance notch, which may be provided on the same side as the conductive component 102, and the clearance space 10112 may be located within the clearance notch. However, it is not limited to this, the brush head body 1011 may also be provided with a clearance groove, which may be provided on the same side as the conductive component 102, and the clearance space 10112 may be located within the clearance groove.

[0165] The cleaning device 10 may include a first conductive element 103 and a second conductive element 104. The first conductive element 103 and the second conductive element 104 may be arranged alternately, and the first conductive element 103 and the second conductive element 104 may be used to transmit electrical energy and electrical signals, respectively. That is, one of the first conductive element 103 and the second conductive element 104 may be an electrode, and the other may be a signal transmission terminal. By arranging the first conductive element 103 and the second conductive element 104 alternately, the distance between the electrode and the signal transmission terminal can be increased, avoiding the problem of short circuits between the electrode and the signal transmission terminal.

[0166] Furthermore, when the base station 20 includes a first transmission head 2032 and a second transmission head 2042, the first conductive element 103 can be correspondingly configured with the first transmission head 2032, and when the cleaning brush head 101 is placed in the placement space 2013, the first conductive element 103 can abut against the first transmission head 2032 to achieve electrical connection. The second conductive element 104 can be correspondingly configured with the second transmission head 2042, and when the cleaning brush head 101 is placed in the placement space 2013, the second conductive element 104 can abut against the second transmission head 2042 to achieve electrical connection.

[0167] Furthermore, the first conductive element 103 and the second conductive element 104 can be located on opposite sides of the brush head body 1011 in the second direction Y. This arrangement further distances the first conductive element 103 from the second conductive element 104, further reducing the risk of a short circuit between the first conductive element 103 and the second conductive element 104.

[0168] In some embodiments, the first conductive element 103 can be a second positive electrode, and the second conductive element 104 can be a second negative electrode. The distance between the first conductive element 103 and the bottom surface of the brush head body 1011 can be greater than the distance between the second conductive element 104 and the bottom surface of the brush head body 1011. The bottom surface of the brush head body 1011 can be the side of the cleaning device 10 that is closest to the surface to be cleaned when cleaning the surface. That is, the first conductive element 103 is positioned higher than the second conductive element 104. This arrangement avoids the problem of a short circuit between the first conductive element 103 and the second conductive element 104 due to water on the surface to be cleaned. Furthermore, since the second negative electrode is generally grounded, a short circuit will only occur when the water level on the surface to be cleaned exceeds the first conductive element 103, thereby further reducing the probability of a short circuit at the second positive electrode.

[0169] The distance between the first conductive element 103 and the bottom surface of the brush head body 1011 can be greater than or equal to 20mm and less than or equal to 60mm. For example, 20mm, 30mm, 40mm, 50mm, 60mm, etc. This setting ensures that the first conductive element 103 has sufficient height to reduce the probability of short circuits in the first conductive element 103. At the same time, it can also avoid the problem of needing to increase the height of the brush head body 1011 due to the first conductive element 103 being set too high, thus reducing the overall height of the brush head body 1011.

[0170] The distance between the second conductive element 104 and the bottom surface of the brush head body 1011 can be greater than or equal to 10mm and less than or equal to 30mm. For example, 10mm, 15mm, 20mm, 25mm, 30mm, etc. This setting avoids the problem of the second conductive element 104 being too low and too close to the bottom surface of the brush head body 1011, thus reducing the risk of short circuit when the second conductive element 104 comes into contact with water on the surface to be cleaned. At the same time, it also avoids the problem of the first conductive element 103 needing to be set higher if the second conductive element 104 is set too high, which further avoids the problem of the brush head body 1011 needing to be set higher, thereby reducing the overall height of the brush head body 1011.

[0171] In some embodiments, the second transmission component 204 may further include a third conductive element 105. The third conductive element 105 can be used to transmit electrical signals and can be spaced apart from the first conductive element 103 and the second conductive element 104. This arrangement increases the distance between the third conductive element 105 and the first conductive element 103 and the second conductive element 104, reducing the probability of a short circuit occurring between the third conductive element 105 and the first conductive element 103 and the second conductive element 104.

[0172] When the base station 20 includes a third transmission head 2043, the third conductive element 105 can be configured to correspond with the third transmission head 2043, and when the cleaning brush head 101 is placed in the placement space 2013, the third conductive element 105 abuts against the third transmission head 2043.

[0173] Furthermore, the third conductive element 105 can be located on a different side of the brush head body 1011 from the first conductive element 103. Since the first conductive element 103 is the first positive electrode, placing the third conductive element 105, which transmits electrical signals, and the first conductive element 103 on the same side of the brush head body 1011 may cause a short circuit.

[0174] The third conductive element 105 and the second conductive element 104 can be located on the same side of the brush head body 1011. Since the second conductive element 104 is the second negative electrode, placing the third conductive element 105 and the second conductive element 104, which transmit electrical signals, on the same side of the brush head body 1011 will not cause a short circuit risk. At the same time, placing the third conductive element 105 and the second conductive element 104 on the same side of the brush head body 1011 can improve the integration of the cleaning brush head 101 and save space in the brush head body 1011.

[0175] The distance between the third conductive element 105 and the bottom surface of the brush head body 1011 can be greater than the distance between the second conductive element 104 and the upper surface of the base 2011. That is, the third conductive element 105 is positioned higher than the second conductive element 104. This arrangement avoids a short circuit between the third conductive element 105 and the second conductive element 104 due to water on the surface to be cleaned. Furthermore, since the third conductive element 105, which transmits electrical signals, is connected to an electrical signal source, and the second negative terminal is generally grounded, a short circuit will only occur when the water level on the surface to be cleaned does not exceed the third conductive element 105, thus further reducing the probability of a short circuit in the third conductive element 105.

[0176] The distance between the third conductive element 105 and the bottom surface of the brush head body 1011 can be greater than or equal to 30mm and less than or equal to 60mm. For example, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc. This setting ensures that the third conductive element 105 has sufficient height to reduce the probability of a short circuit. Simultaneously, it avoids the problem of needing to raise the cleaning brush head 101 due to the third conductive element 105 being set too high, thus reducing the overall height of the cleaning brush head 101.

[0177] In some embodiments, the second conductive element 104 has a first center point, and the third conductive element 105 has a second center point. The first center point and the second center point can be offset in the forward direction of the cleaning device 10. This arrangement allows the second conductive element 104 and the third conductive element 105 to be misaligned in the forward direction of the cleaning device 10, preventing the second conductive element 104 from accidentally contacting the third transmission head 2043 during the process of the cleaning device 10 being pushed into or entering the placement space 2013, thus avoiding problems such as false triggering of signal communication and power supply.

[0178] The first center point and the second center point can be staggered in the height direction Z of the cleaning device 10. This arrangement allows the second guide to be staggered with the third conductive member 105 in the height direction Z, preventing the second conductive member 104 from accidentally contacting the third transmission head 2043 during the placement of the cleaning device 10 in the placement space 2013 along the height direction Z, which could lead to problems such as false triggering of signal communication and power supply.

[0179] In some embodiments, such as Figures 10 to 11As shown, the cleaning device 10 may further include an electrical connector 108. The electrical connector 108 may be disposed on the brush head body 1011, and may be disposed on the same side as the conductive element 102. The electrical connector 108 may be located on the side of the conductive element 102 away from the brush head body 1011. The electrical connector 108 is electrically connected to the conductive element 102 for transmitting electrical energy and / or electrical signals. It is understood that the electrical connector 108 may electrically connect the conductive element 102 and the electrical components and / or signal processor within the cleaning brush head 101 to further transmit the electrical energy and / or electrical signals transmitted by the conductive element 102 to the electrical components and / or signal processor. Simultaneously, by positioning the electrical connector 108 on the side of the conductive element 102 away from the brush head body 1011, structural components such as the liquid storage tank 1012 can be used to shield and protect the electrical connector 108, preventing it from coming into contact with liquids in the external environment and causing a short circuit.

[0180] The cleaning device 10 may include a first electrical connector 109 and a second electrical connector 110. The first electrical connector 109 is electrically connected to a first conductive element 103 for transmitting electrical energy and / or electrical signals transmitted by the first conductive element 103. The first electrical connector 109 may be disposed on the same side as the first conductive element 103 and may be located on the side of the first conductive element 103 closer to the liquid supply tank. The second electrical connector 110 is electrically connected to a second conductive element 104 for transmitting electrical energy and / or electrical signals transmitted by the first conductive element 103. The second electrical connector 110 may be disposed on the same side as the second conductive element 104 and may be located on the side of the second conductive element 104 closer to the liquid supply tank.

[0181] The cleaning device 10 may further include a third electrical connector 111. The third electrical connector 111 may be electrically connected to the third conductive element 105 for transmitting electrical signals transmitted by the third conductive element 105.

[0182] The third electrical connector 111 can be disposed on the same side as the third conductive member 105 and located on the side of the third conductive member 105 closer to the liquid supply tank. There is a gap between the third electrical connector 111 and the second electrical connector 110 to avoid short circuit between the third electrical connector 111 and the second electrical connector 110.

[0183] The second electrical connector 110 may have a third center point, and the third electrical connector may have a fourth center point. The third and fourth center points may be offset in the forward direction of the cleaning device 10. This arrangement allows the second electrical connector 110 and the third electrical connector 111 to be offset in the forward direction of the cleaning device 10, saving space occupied by the second electrical connector 110 and the third electrical connector 111 and improving the space utilization of the brush head body 1011. At the same time, it also facilitates the connection of the second electrical connector 110 and the third electrical connector 111 to the circuit and reduces the risk of short circuits in the second electrical connector 110 and the third electrical connector 111.

[0184] The third and fourth center points can be offset in the second direction Y. This arrangement allows the second electrical connector 110 and the third electrical connector 111 to be staggered in the second direction Y, saving space occupied by the second and third electrical connectors 110 and improving the space utilization of the brush head body 1011. Simultaneously, it facilitates the connection of the second and third electrical connectors 110 and 111 to the circuit, and reduces the risk of short circuits between them.

[0185] In some embodiments, the cleaning device 10 may further include a handle assembly, which can be connected to the cleaning brush head 101 for a user to operate and hold. By holding the handle assembly, the user controls the cleaning brush head 101 to move on the surface to be cleaned, thereby achieving the purpose of cleaning the surface to be cleaned.

[0186] The cleaning brush head 101 can be movably connected to the handle assembly, such as by pivoting or ball joint. When the user holds the handle assembly and moves the cleaning brush head 101 over the surface to be cleaned, the relative angle between the handle assembly and the cleaning brush head 101 can be adjusted by moving the handle assembly and the cleaning brush head 101, thereby changing the operating angle and flexibly adjusting the cleaning posture for easier cleaning operation.

[0187] In some embodiments, such as Figures 10 to 15 As shown, along the forward direction of the cleaning device 10, the liquid storage tank 1012 can be located in front of the walking part 107, that is, the liquid storage tank 1012 is positioned in front of the walking part 107, so that the center of gravity of the liquid storage tank 1012 is located on the brush head body 1011 closer to the cleaning working part 106, so as to further realize the forward shift of the center of gravity of the cleaning brush head 101, and the weight of the liquid storage tank 1012 can be applied more to the cleaning working part 106, so as to further increase the downward pressure on the surface to be cleaned by the cleaning working part 106 located in front of the brush head body 1011.

[0188] The liquid reservoir 1012 and the cleaning work section 106 have at least a partial overlap in their orthographic projections onto the surface to be cleaned along the height direction Z of the cleaning device 10, meaning that at least a portion of the liquid reservoir 1012 is directly above the cleaning work section 106. By positioning at least a portion of the liquid reservoir 1012 directly above the cleaning work section 106, the weight of at least a portion of the liquid reservoir 1012 can directly act on the cleaning work section 106, thereby increasing the downward pressure exerted by the cleaning work section 106 on the surface to be cleaned. This relatively increases the friction between the cleaning work section 106 and the surface to be cleaned, thus improving the cleaning effect.

[0189] In some embodiments, the orthographic projection of the liquid storage tank 1012 along the height direction Z of the cleaning device 10 completely covers the orthographic projection of the cleaning work part 106 along the height direction Z of the cleaning device 10, so that more of the weight of the liquid storage tank 1012 can directly act on the cleaning work part 106, thereby further increasing the downward pressure on the surface to be cleaned by the cleaning work part 106, and further increasing the friction between the cleaning work part 106 and the surface to be cleaned, thereby further improving the cleaning effect.

[0190] In the second direction Y, the liquid storage tank 1012 and the walking part 107 have an overlapping portion, which can effectively utilize the space of the cleaning brush head 101 in the second direction Y, so that the liquid storage tank 1012 has a larger size in the second direction Y, thereby increasing the volume of the liquid storage tank 1012.

[0191] The volume of the liquid storage tank 1012 can be 800ml to 1200ml, such as 800ml, 850ml, 900ml, 950ml, 1000ml, 1050ml, 1100ml, 1150ml, 1200ml, etc., which will not be listed here. Since the liquid storage tank 1012 is located on the side of the walking part 107 close to the cleaning work part 106, the size of the liquid storage tank 1012 can be designed to be relatively large, so that the liquid storage tank 1012 can meet the requirement of a volume of 800ml or more, thereby increasing the usable time of the cleaning fluid in the cleaning equipment 10, and thus increasing the duration of a continuous cleaning operation, thereby improving the user experience.

[0192] In some embodiments, such as Figure 14 As shown, when the cleaning brush head 101 is docked with the base station 20, it can move along the length direction W of the base station 20 onto the base station 20. It can also be as follows... Figure 15 As shown, the cleaning device 10 moves along the height direction Z of the base station 20 to perform at least one function on the base station 20, such as docking, charging, self-cleaning, sewage discharge, and water replenishment. In other words, when the cleaning device 10 docks with the base station 20, it can simultaneously achieve push-in docking and placement docking, which increases the functionality of the cleaning system and improves the user experience.

[0193] like Figures 14 to 19 As shown, the base station 20 may also include a ramp 21, and the cleaning device 10 can move along the length W of the base station 20 through the ramp 21 to the base station 20; in the length W of the base station 20, the base station 20 has a first pair of interfaces 227, and in the height Z of the base station 20, the base station 20 has a second pair of interfaces 228; the cleaning brush head 101 can be connected to the base station 20 through the first pair of interfaces 227 or the second pair of interfaces 228.

[0194] The base station 20 includes a main body 201, and a ramp 21 is located on one side of the main body 201 along the length W of the base station 20. The ramp 21 has a first end and a second end opposite to each other along the length W of the base station 20. The first end is connected to the main body 201, and the second end is located on the base 2011. By providing the ramp 21, the cleaning brush head 101 can be directly connected to the base station 20 from the ramp 21 by the user's push, without requiring the user to lift the cleaning brush head 101. This facilitates the connection between the cleaning brush head 101 and the base station 20 and improves the user experience.

[0195] In some embodiments, the cleaning brush head 101 has a push-in guide structure configured to guide the cleaning brush head 101 when the cleaning device 10 moves horizontally onto the base station 20, i.e., to guide the cleaning brush head 101 to dock with the base station 20 through the first pair of interfaces 227. By providing the push-in guide structure, a guiding effect can be formed when the user pushes the cleaning brush head 101 to dock with the base station 20, enabling the cleaning brush head 101 and the base station 20 to dock accurately and quickly, thereby improving the user experience.

[0196] Among them, such as Figures 14 to 19 As shown, the push-in guide structure includes at least one first guide wheel 251. By setting the first guide wheel 251, when the user pushes the cleaning brush head 101 to connect with the base station 20, the rotation of the first guide wheel 251 can form a guiding effect. At the same time, the first guide wheel 251 can reduce the resistance when the cleaning brush head 101 connects with the base station 20, thereby reducing the pushing force required by the user when pushing the cleaning brush head 101 to connect with the base station 20, thus improving the user experience.

[0197] The ramp 21 is equipped with a first guide wheel 251. When the user pushes the cleaning brush head 101 on the ramp 21, the cleaning brush head 101 is in a climbing state because the ramp 21 is tilted. The first guide wheel 251 reduces the resistance of the cleaning brush head 101 on the ramp 21, thereby reducing the pushing force required by the user and improving the user experience.

[0198] The ramp 21 may be provided with two first guide wheels 211, which may be spaced apart along the second direction Y and positioned close to the first pair of interfaces 227 along the length direction W of the base station 20. This provides better guidance at the transition point where the ramp 21 connects to the first pair of interfaces 227, preventing the bottom of the cleaning brush head 101 from rubbing against the top of the ramp 21. Of course, more first guide wheels 211 may be provided on the ramp 21, and multiple first guide wheels 211 may be positioned at other locations on the ramp 21; this disclosure does not impose any limitations on this.

[0199] The first guide wheel 211 can be rotatably mounted via a first rotating shaft. A first mounting groove can be formed on the ramp plate 21, and the first rotating shaft is located in the first mounting groove. That is, the portion of the first guide wheel 211 above the first rotating shaft can protrude from the surface of the ramp plate 21, thus providing support and guidance for the cleaning brush head 101 while preventing the first guide wheel 211 from being too high. The first guide wheel 211 and the first rotating shaft can be an integral structure or a separate structure.

[0200] The first rotating shaft is perpendicular to the length direction W of the base station 20, meaning that the rotation direction of the first guide wheel 211 is along the length direction W of the base station 20, facing the front or rear of the base station 20. This provides better guidance when the cleaning brush head 101 engages with or disengages from the base station 20 along the length direction W. Of course, the first guide wheel 211 can also be a caster wheel, and this disclosure does not limit this.

[0201] Among them, such as Figures 14 to 16 As shown, the ramp 21 is provided with an anti-slip structure 212, which is located in the area traversed by the walking part 107 of the cleaning brush head 101 to prevent the walking part 107 from slipping when the cleaning brush head 101 climbs on the ramp 21. The anti-slip structure 212 may be a raised stripe structure formed on the surface of the ramp 21, and the extension direction of the stripe structure may be a second direction Y, that is, perpendicular to the movement direction of the walking part 107 on the ramp 21.

[0202] In some embodiments, the angle between the ramp 21 and the horizontal plane is no greater than 20°, so that the upward angle of the cleaning brush head 101 can be controlled below 20°, which can improve the user's experience of pushing the cleaning brush head 101 onto the pile.

[0203] The angle between the ramp slab 21 and the horizontal plane can be 10° to 20°, such as 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, etc., which will not be listed here in this disclosure.

[0204] like Figures 14 to 20As shown, the stop structure 2012 may include a first side portion 20121, a second side portion 20122, and a third side portion 20123. The first side portion 20121 and the ramp plate 21 are located on both sides of the base body 2011 along the length direction W of the base station 20, and the second side portion 20122 and the third side portion 20123 are located on both sides of the base body 2011 along the second direction Y. The first transmission component 203 and the second transmission component 204 are located on the second side portion 20122 and the third side portion 20123, respectively.

[0205] The base station 20 includes a drying module 22. The main body 201 has a receiving space, and a first side portion 20121 has an air outlet 20124. The drying module 22 is located within the receiving space of the main body 201 and is configured to output hot air through the air outlet 20124. The drying module 22 utilizes the space of the main body 201, avoiding the drying module 22 occupying space along the length W of the base station 20. While keeping the length of the base station 20 constant or substantially constant, the length of the ramp 21 is relatively increased. This increased length of the ramp 21 relatively reduces its slope, ultimately allowing the upward angle of the cleaning brush head 101 to be controlled below 20°, saving the thrust required by the user and improving the user experience.

[0206] Among them, the ramp 21 is used to support the cleaning equipment 10. The ramp surface of the ramp 21 is an inclined plane, that is, the ramp surface of the ramp 21 is an inclined plane. When the cleaning brush head 101 travels on the ramp 21, there is no bump caused by the change of slope, and the stability is good, which can improve the user's experience of pushing the cleaning brush head 101 onto the pile.

[0207] It is understood that the ramp slab 21 may also include multiple slopes along its length W, with adjacent slopes directly connected or connected through a transition surface; the angle between the transition surface and the horizontal plane is smaller than the angle between the two adjacent slopes and the horizontal plane. The angles between the multiple slopes and the horizontal plane may be the same or different, and the angles with the horizontal plane can be 10° to 20°.

[0208] Among them, such as Figure 16 , Figure 18 and Figure 19As shown, a cleaning groove 205 is formed on the main body 201, which is used to place the cleaning head 130 of the cleaning brush head 101. An air outlet 20124 can be located on the first side portion 20121, that is, along the height direction Z, the air outlet 20124 is located above the cleaning groove 205, so that hot air at a preset temperature is output through the air outlet 20124 to dry the cleaning roller. The preset temperature can be 40℃~90℃, for example 40℃, 45℃, 50℃, 55℃, 60℃, 65℃, 70℃, 75℃, 80℃, 85℃, 90℃, etc., which are not listed here. By using high-temperature drying gas, the cleaning roller can be dried quickly, avoiding problems such as odor and bacterial growth caused by moisture, thus improving the user experience.

[0209] Among them, such as Figure 16 As shown, multiple air outlets 20124 are distributed in the second direction Y, and the width of the distribution area is comparable to the length of the cleaning work section 106, so as to dry each position on the cleaning work section 106 at the same time and improve the drying effect.

[0210] Among them, such as Figure 16 As shown, multiple air vents 20124 can be installed in the height direction Z of the base station 20, for example, two rows of air vents 20124 can be installed to simultaneously dry multiple positions around the cleaning work section 106, thereby improving the drying effect. When multiple air vents 20124 are installed, the two air vents 20124 corresponding to two adjacent rows of air vents 20124 in the height direction Z can be staggered in the second direction Y, so that each position on the cleaning work section 106 can be directly dried by hot air, thereby improving the drying effect.

[0211] In this system, after the cleaning brush head 101 is connected to the base station 20, the height of the first side portion 20121 in the height direction Z can be greater than the height of the cleaning head 130 in the cleaning brush head 101. By making the height of the first side portion 20121 greater than the height of the cleaning head 130 in the cleaning brush head 101, on the one hand, when the cleaning head 130 performs self-cleaning on the base station 20, the cleaning liquid sprayed by the cleaning head 130 will be thrown out during the rotation process. The higher first side portion 20121 can form a barrier to the thrown cleaning liquid, preventing the cleaning liquid from being thrown out of the base station 20; on the other hand, when the self-cleaned cleaning working part 106 is dried by the drying module 22, the higher first side portion 20121 can extend the flow path of the drying gas around the cleaning working part 106, thereby increasing the air temperature around the cleaning working part 106 and thus improving the drying efficiency of the cleaning working part 106.

[0212] Among them, such as Figures 16 to 20As shown, the base station 20 also includes a base plate 20111 and a support plate 20112. The first end of the ramp plate 21 is connected to the support plate 20112, and a cleaning groove 205 is formed on the support plate 20112. The base plate 20111, the support plate 20112, the side plates of the base 2011, and the ramp plate 21 enclose and form a receiving space under the support plate 20112 and a receiving space under the ramp plate 21. That is, target devices can be assembled under both the support plate 20112 and the ramp plate 21 to save the size of the main body 201 in the length direction W.

[0213] The drying module 22 includes a fan 221, a fan housing 222, a heater 223, and an air duct 224. The fan 221 is assembled inside the fan housing 222, which is connected to a support plate 20112. The air inlet of the heater 223 is connected to the air outlet 20124 of the fan housing 222, and the air outlet 20124 of the heater 223 is connected to the air inlet of the air duct 224. The air outlet 20124 of the air duct 224 is the air outlet 20124 on the first side 20121. There is a gap between the fan housing 222 and the support plate 20112, which serves as the air inlet of the fan housing 222. The fan housing 222 and the support plate 20112 can be connected by screws, so that there is a gap between the fan housing 222 and the support plate 20112 around the circumference of the fan 221, allowing air to enter around the circumference.

[0214] The base plate 20111 is provided with an air inlet structure 20113. The gap between the fan housing 222 and the support plate 20112 is connected to the air inlet structure 20113 so that air from the outside of the base station 20 can be drawn in through the air inlet structure 20113. After being heated by the heater 223, the air inlet structure 20113 dries the cleaning roller through the air outlet 20124.

[0215] The air intake structure 20113 can be a grid structure formed on the base plate 20111. The air intake structure 20113 can sink down along the height direction ZZ towards the support plate 20112 to increase the distance between the air intake structure 20113 and the bearing surface of the base station 20, which is conducive to the air at the bottom of the base station 20 entering the fan 221 through the air intake structure 20113.

[0216] The air intake structure 20113 is equipped with a filter element 20114, which is located in the receiving space. The filter element 20114 filters the air drawn in through the air intake structure 20113, preventing foreign objects, dust, and sewage from entering the fan 221 through the air intake structure 20113, thus improving the service life and reliability of the fan 221. The filter element 20114 can be, for example, a sponge, and can be secured to the air intake structure 20113 with hooks, improving the cost-effectiveness of later maintenance. Of course, the filter element 20114 can also be a filter screen, paper-based filter element, etc., and can be fixed in the receiving space by adhesive, threaded connection, or other methods; this disclosure does not limit this.

[0217] Among them, such as Figure 17 As shown, the air intake structure 20113 and the filter element 20114 are located in the accommodating space below the ramp plate 21, saving the accommodating space below the support plate 20112. This allows for a further reduction in the length of the base station body, while relatively increasing the length of the ramp plate 21, thus further reducing the slope of the ramp plate 21. It is understood that other devices of suitable height can be installed in the accommodating space below the ramp plate 21 to reduce the accommodating space occupied by the devices below the support plate 20112, and this disclosure does not impose any limitations on this.

[0218] Among them, such as Figure 20 As shown, the base station 20 also includes a circuit board 225, which is disposed in the accommodating space. The air inlet of the fan 221 and the orthographic projection of the circuit board 225 along the second direction Y on the preset reference plane have an overlapping portion, that is, the gap between the fan housing 222 and the support plate 20112 can draw in air around the circuit board 225, thereby increasing the air flow speed around the circuit board 225, reducing the temperature of the air around the circuit board 225, and achieving cooling of the circuit board 225, so that the circuit board 225 is within the normal operating temperature range.

[0219] The distance between the air intake structure 20113 and the circuit board 225 along the length direction W is no more than 5cm, such as 5cm, 4cm, 3cm, 2cm, 1cm, etc., which can better improve the air flow speed around the circuit board 225, so as to reduce the temperature of the air around the circuit board 225 and achieve cooling of the circuit board 225.

[0220] Among them, such as Figure 20 As shown, a clearance notch 2251 is formed on the circuit board 225, and the clearance notch 2251 is located between the circuit board 225 and the heater 223 along the second direction Y. The circuit board 225 avoids the heater 223 by using the clearance notch 2251, thus preventing the heat generated when the heater 223 heats the gas sucked in by the fan 221 from affecting the normal operation of the circuit board 225 and improving the reliability of the circuit board 225.

[0221] Among them, such as Figure 20 As shown, the heater 223, circuit board 225, and fan 221 are located between the drying duct 224 and the ramp 21 along the length direction W. That is, the heater 223 and fan 221 and circuit board 225 are distributed in the width direction, which saves the space occupied by the base station in the length direction W, thereby further shortening the length of the base station, while relatively increasing the length of the ramp 21, and further reducing the slope of the ramp 21.

[0222] Among them, such as Figure 20 As shown, the base station 20 also includes a control component 226, which is located between the drying air duct 224 and the ramp 21 along the length direction W. That is, the control component 226 and the circuit board 225 are distributed in the second direction Y, which saves the space occupied by the base station in the length direction W, thereby further shortening the length of the base station body, while relatively increasing the length of the ramp 21, and further reducing the slope of the ramp 21.

[0223] The base plate 20111 and the support plate 20112 can be used to form an air duct 224, that is, the base plate 20111 and the support plate 20112 are fastened together to form an air duct 224; the air duct 224 can also be formed directly on the support plate 20112 or the base plate 20111, or the air duct 224 can be formed as an independent structural component set between the base plate 20111 and the support plate 20112. This disclosure does not limit this.

[0224] The base plate 20111 can be provided with assembly structures for assembling the heater 223, circuit board 225, and control component 226, forming a positioning assembly and improving the assembly efficiency, assembly accuracy, and post-assembly stability of each component in the base station 20. The assembly structure corresponding to each component only needs to match the shape and size of each component; this disclosure does not impose any limitations in this regard.

[0225] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
