Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and a cleaning robot. Background Technology

[0002] Cleaning robots are robotic systems capable of autonomously or semi-autonomously performing environmental cleaning tasks. With the rapid development of sensor technology, artificial intelligence, computing power, and mechatronics, cleaning robots have evolved from simple automated equipment into intelligent agents with certain environmental perception, decision-making, planning, and task execution capabilities. Their application scenarios have also expanded from the initial household sweeping robots to commercial (such as shopping malls and office buildings), industrial (such as factory workshops and cleanrooms), and other specialized fields.

[0003] Cleaning robots include cleaning devices, which often suffer from poor cleaning results compared to traditional cleaning devices. Utility Model Content

When the drive gear rotates forward, the drive assembly drives the support assembly to rotate the mop, the meshing unit stops meshing with the rack, and the cleaning mechanism can move to the first position. When the drive gear rotates in reverse, the meshing unit meshes with the rack, and the cleaning mechanism can move to the second or third position.

[0032] In one embodiment, the meshing unit includes a drive gear and a meshing gear connected to each other. The drive gear drives the drive gear to rotate.

[0059] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0060] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0061] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0064] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0065] See Figure 1 , Figure 2 , Figure 3 and Figure 7 An embodiment of this application provides a cleaning device 10 including a base 100, a first drive mechanism 200, and a cleaning mechanism 300. The first drive mechanism 200 includes a housing 210, a drive assembly 220, and a water pump 230. The housing 210 is connected to the base 100, and the drive assembly 220 and water pump 230 are disposed within the housing 210. The cleaning mechanism 300 includes a support assembly 310 and a mop 320. The support assembly 310 is connected to the housing 210, and the mop 320 is sleeved on the support assembly 310. The mop 320 is capable of rotating relative to the support assembly 310 along its circumference. When the mop 320 is mounted on the support assembly 310, the mop 320 has a first cleaning surface 321 and a second cleaning surface 322, which are arranged at an included angle. The first cleaning surface 321 is used to clean a first working surface, and the second cleaning surface 322 is used to clean a second working surface, with an included angle between the first and second working surfaces. Therefore, by setting the first cleaning surface 321 and the second cleaning surface 322 at an angle, the mop 320 can simultaneously clean the first and second working surfaces at the angle, thus improving the working efficiency and cleaning effect of the cleaning device 10. For example, the first working surface can be the ground, and the second working surface can be a wall. The wall and the ground can be connected perpendicularly. The first cleaning surface 321 can extend horizontally, and the second cleaning surface 322 can extend vertically. In this case, the first cleaning surface 321 and the second cleaning surface 322 can be perpendicular to each other. In other embodiments, the first and second working surfaces can be set at an acute or obtuse angle. In this case, the first cleaning surface 321 and the second cleaning surface 322 can also be set at an acute or obtuse angle.

[0066] See Figure 7When the drive assembly 220 drives the support assembly 310 on the cleaning mechanism 300 to rotate the mop 320, the drive assembly 220 drives the water pump 230 to pump water to the mop 320. When the drive assembly 220 stops driving the support assembly 310 on the cleaning mechanism 300 to rotate the mop 320, the drive assembly 220 stops driving the water pump 230 to pump water to the mop 320. Therefore, during the process of cleaning the first and second working surfaces by rotating the mop 320, the water pump 230 pumps cleaning fluid to the mop 320, thereby wetting the mop 320 under the action of the cleaning fluid, thus improving the cleaning effect of the mop 320 and the entire cleaning device 10. Furthermore, when the mop 320 stops rotating to stop cleaning, the water pump 230 will automatically stop pumping cleaning fluid to the mop 320 to avoid wasting cleaning resources, thereby improving the ease of use of the cleaning device 10. In this embodiment, the cleaning fluid can be cold water, hot water, disinfectant, cleaning solution, or other liquids used for cleaning.

[0067] See Figure 5 , Figure 6 and Figure 7 In some embodiments, the drive assembly 220 includes a drive gear 221 and a peristaltic gear 222, both of which are rotatably connected to the housing 210. The water pump 230 includes a peristaltic pump. The drive gear 221 drives the peristaltic gear 222 to move. For example, the drive gear 221 can transmit power to the peristaltic gear 222 through the transmission of one or more intermediate gears, thereby driving the peristaltic gear 222 to rotate. When the drive gear 221 rotates forward, the peristaltic gear 222 drives the peristaltic pump to pump water; when the drive gear 221 rotates in reverse, the peristaltic gear 222 stops driving the peristaltic pump to pump water. It is understood that the peristaltic pump may include a pump head 231 and a hose 232. The pump head 231 is connected to the peristaltic gear 222, allowing the pump head 231 to rotate following the peristaltic gear 222. One end of the hose 232 can be connected to the water storage chamber, and the other end of the hose 232 can be positioned close to the mop 320. When the drive gear 221 rotates forward to drive the peristaltic gear 222 to rotate forward, the pump head 231 rotates forward to squeeze the hose 232, thereby drawing water pump 230 from the water storage chamber into the hose through peristalsis and allowing it to flow from the other end of the hose into the mop 320, thus wetting the mop 320. When the drive gear 221 rotates in reverse to drive the peristaltic gear 222 to rotate in reverse, the pump head 231 rotates in reverse to squeeze the hose 232. At this time, the rotating pump head 231 cannot draw water pump 230 from the water storage chamber into the hose. Specifically, when the forward rotation is clockwise, the corresponding reverse rotation is counterclockwise; when the forward rotation is counterclockwise, the corresponding reverse rotation is clockwise.

[0068] See Figure 5 , Figure 6 and Figure 7In some embodiments, the support assembly 310 includes a support member 311 and a drive shaft 312. The drive shaft 312 is rotatably mounted on the support member 311 and can be connected to the drive assembly 220. The drive assembly 220 drives the drive shaft 312 to rotate relative to the support member 311. The mop 320 is sleeved on the support member 311 and covers the drive shaft 312, thus abutting against it. When the drive shaft 312 rotates, friction is generated between it and the mop 320, causing the mop 320 to rotate relative to the support member 311 under the action of this friction, thereby achieving the cleaning function of the mop 320 on the first and second working surfaces. For example, the support member 311 can be approximately a triangular prism structure, and the drive shaft 312 can be provided on each of the three edges of the support member 311. It can be understood that the mop 320 moves in a track-like motion relative to the support member 311. In other embodiments, the support assembly 310 includes a support member 311, which is rotatably connected to the housing 210. The support member 311 has a prism structure, which can be understood as a prism-shaped roller structure. The mop 320 is fixedly sleeved on the support member 311. At this time, the mop 320 also has a first cleaning surface 321 and a second cleaning surface 322 set at an angle. When the support member 311 rotates, the mop 320 rotates synchronously with the support member 311.

[0069] See 3. Figure 6 , Figure 7 and Figure 13 In some embodiments, the drive assembly 220 includes a drive gear 221, a helical gear 223, a transmission gear 224, and a telescopic member 225. The telescopic member 225 is disposed on the transmission gear 224; for example, the telescopic member 225 may be fixedly connected to the transmission gear 224, and the helical gear 223 meshes with the transmission gear 224. The drive gear 221 drives the transmission gear 224 to rotate via the helical gear 223. For example, the drive gear 221 may transmit power to the helical gear 223 through the transmission of one or more intermediate gears, thereby driving the helical gear 223 and the transmission gear 224 to rotate. When the drive gear 221 rotates forward, the telescopic member 225 is connected to the drive shaft 312, the mop 320 rotates, and / or the water pump 230 pumps water; when the drive gear 221 rotates in reverse, the telescopic member 225 disengages from the drive shaft 312, the mop 320 stops rotating, and / or the water pump 230 stops pumping water.

[0070] For example, when the drive gear 221 rotates forward, the helical gear 223 also rotates forward. Simultaneously, the helical gear 223 drives the transmission gear 224 to rotate forward, and the helical gear 223 also causes the transmission gear 224 to slide along the axial direction of the helical gear 223. This causes the transmission gear 224 and the telescopic member 225 to move closer to the transmission shaft 312 until the telescopic member 225 inserts into the transmission shaft 312 and forms a connection. This allows the power of the drive gear 221 to be transmitted to the transmission shaft 312 through the helical gear 223, the transmission gear 224, and the telescopic member 225. In other words, the drive gear 221 drives the transmission shaft 312 to move. When the drive gear 221 rotates forward to drive the transmission shaft 312 to rotate and drive the mop 320 to clean, the drive gear 221 can also transmit power to the peristaltic gear 222, causing the pump head 231 of the peristaltic pump to rotate forward to pump water 230 into the mop 320. This wets the mop 320 during the cleaning process, thereby improving the cleaning effect.

[0071] For example, when the drive gear 221 reverses, the helical gear 223 also reverses. Simultaneously, the helical gear 223 drives the transmission gear 224 to reverse, and the helical gear 223 also causes the transmission gear 224 to slide along the axial direction of the helical gear 223. This causes the transmission gear 224 and the telescopic member 225 to move away from the transmission shaft 312 until the telescopic member 225 is completely withdrawn from the transmission shaft 312 and disconnected from it. This prevents the power of the drive gear 221 from being transmitted to the transmission shaft 312 via the helical gear 223, transmission gear 224, and telescopic member 225; in other words, the drive gear 221 cannot drive the transmission shaft 312 to move. When the transmission shaft 312 cannot rotate, the mop 320 also cannot rotate relative to the support member 311 for cleaning. At this time, the drive gear 221 causes the peristaltic pump head 231 to reverse, preventing the water pump 230 from entering the mop 320 and avoiding water waste.

[0072] See Figure 2 , Figure 3 , Figure 4 and Figure 6In some embodiments, one of the support component 310 and the housing 210 is provided with a guide groove 211, and the other includes a guide rib 3111. The guide rib 3111 cooperates with the guide groove 211. For example, the housing 210 has a guide groove 211 that extends horizontally, and the guide rib 3111 is provided on the support component 310. The shape of the guide rib 3111 matches that of the guide groove 211 and extends horizontally. During the assembly process of the cleaning mechanism 300 and the first drive mechanism 200, the guide rib 3111 can be first engaged with the guide groove 211, and the cleaning mechanism 300 can be installed in place by sliding the guide rib 3111 relative to the guide groove 211. Therefore, the cooperation between the guide rib 3111 and the guide groove 211 can play a good guiding role for the cleaning mechanism 300, thereby improving the assembly efficiency and assembly accuracy of the cleaning mechanism 300.

[0073] See Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments, the support component 310 and the housing 210 are detachably connected. For example, one of the support component 310 and the housing 210 may have a locking hole 212, and the other may have a connecting buckle 3112. The connecting buckle 3112 engages with the locking hole 212, thereby enabling the support component 310 and the housing 210 to be connected by a locking mechanism. During assembly, through the engagement of the guide rib 3111 and the guide groove 211, when the cleaning mechanism 300 is installed in place, the connecting buckle 3112 will also engage with the locking hole 212, thereby achieving a fixed connection between the cleaning mechanism 300 and the housing 210. When it is necessary to unload the cleaning mechanism 300 from the first drive mechanism 200, the engagement between the connecting buckle 3112 and the locking hole 212 is first released, and then the guide rib 3111 is slid relative to the guide groove 211, so that the cleaning mechanism 300 is completely disengaged from the first drive mechanism 200 to achieve the unloading of the cleaning mechanism 300. Therefore, the support component 310 and the housing 210 are detachably connected, which facilitates the maintenance of the cleaning mechanism 300 and improves the ease of use of the cleaning device 10.

[0074] See Figure 8 , Figure 9 , Figure 10 and Figure 11In some embodiments, the cleaning device 10 further includes a second drive mechanism 400, which also includes a housing 210 and a drive assembly 220. The housing 210 is at least partially housed within the receiving cavity 110 and connected to the support assembly 310 on the cleaning mechanism 300. The drive assembly 220 is disposed within the housing 210 and drives the housing 210 to move relative to the base 100, thereby causing the cleaning mechanism 300 to follow the movement of the housing 210 relative to the base 100. Therefore, the cleaning mechanism 300 has multiple positions relative to the base 100, allowing it to cyclically reciprocate between these positions. By enabling the cleaning mechanism 300 to move between multiple positions relative to the base 100, the switching of various cleaning functions of the cleaning mechanism 300 can be achieved, thereby improving the applicability of the cleaning mechanism 300 to various working conditions and ultimately enhancing the ease of use of the cleaning device 10.

[0075] For example, when switching between multiple positions, the cleaning mechanism 300 retracts or extends horizontally, and / or the cleaning mechanism 300 rises or falls vertically. And / or, the mop 320 in multiple positions includes any two of the following: both the first cleaning surface 321 and the second cleaning surface 322 of the mop 320 are located within the receiving cavity 110; both the first cleaning surface 321 and the second cleaning surface 322 of the mop 320 are located outside the receiving cavity 110; the first cleaning surface 321 of the mop 320 is located outside the receiving cavity 110 and the second cleaning surface 322 is located inside the receiving cavity 110; the first cleaning surface 321 of the mop 320 is located inside the receiving cavity 110 and the second cleaning surface 322 is located outside the receiving cavity 110.

[0076] In some examples, the cleaning mechanism has a first position and a second position, and a drive assembly is used to move the cleaning mechanism between the first position and the second position, enabling the cleaning mechanism to retract or extend horizontally, or to rise or fall vertically. In other examples, the base of the cleaning robot is provided with a receiving cavity, into which the cleaning mechanism is housed. When the mop on the cleaning mechanism is in the first and second positions, the relationship between the mop and the receiving cavity can be any two of the following: first, both the first and second cleaning surfaces of the mop are located inside the receiving cavity; second, both the first and second cleaning surfaces of the mop are located outside the receiving cavity; third, the first cleaning surface of the mop is located outside the receiving cavity, and the second cleaning surface is located inside the receiving cavity; fourth, the first cleaning surface of the mop is located inside the receiving cavity, and the second cleaning surface is located outside the receiving cavity. Similarly, in other examples, the cleaning mechanism can have a first position, a second position, and a third position. The drive assembly can be used to move the cleaning mechanism between these positions, for example, from the first position to the second or third position, and from the second or third position back to the first position. In this example, different positions allow the cleaning mechanism to retract or extend horizontally, or to rise or fall vertically. The mop on the cleaning mechanism also has different configurations depending on its position, such as the first cleaning surface of the mop being located within the receiving cavity, etc., which will not be elaborated further here. Different horizontal positions allow the mop on the cleaning mechanism to expand or retract, enabling cleaning of blind spots when expanding. Different vertical positions allow the mop on the cleaning mechanism to rise or fall, preventing the mop from contacting the working surface when rising. In some examples, the cleaning mechanism has a first position, a second position, and a third position, with the third position higher than the first and second positions, and the first position further away from the cleaning robot than the second position. This allows the same cleaning mechanism to retract or extend, as well as to rise or fall.

[0077] This application's embodiments are mainly described using a cleaning mechanism having a first position, a second position, and a third position as an example. For details, please refer to [link / reference needed]. Figure 12 , Figure 13 , Figure 14 and Figure 15The cleaning mechanism 300 has a first position 301, a second position 302, and a third position 303. The drive assembly 220 is also used to move the cleaning mechanism 300 from the first position 301 to the second position 302 or the third position 303, or from the first position 301 through the second position 302 to the third position 303. Movement between the different positions allows the cleaning mechanism to retract or extend horizontally, or to rise or fall vertically. Similarly, in other examples, the base of the cleaning robot is provided with a receiving cavity, and the cleaning mechanism is housed in the receiving cavity. When the mop on the cleaning mechanism moves between different positions, the relationship between the mop and the receiving cavity can be any two of the following: the first is that both the first cleaning surface and the second cleaning surface of the mop are located inside the receiving cavity; the second is that both the first cleaning surface and the second cleaning surface of the mop are located outside the receiving cavity; the third is that the first cleaning surface of the mop is located outside the receiving cavity, and the second cleaning surface is located inside the receiving cavity; the fourth is that the first cleaning surface of the mop is located inside the receiving cavity, and the second cleaning surface is located outside the receiving cavity.

[0078] See Figure 12 , Figure 13 , Figure 14 and Figure 15In some embodiments, the drive assembly 220 includes a drive gear 221, an engagement unit 226, and a rack 227. Both the drive gear 221 and the engagement unit 226 are rotatably connected to the housing 210, and the rack 227 is slidably connected to the housing 210 and can abut against the base 100. When the drive gear 221 rotates forward, the drive assembly 220 drives the telescopic member 225 to insert into the transmission shaft 312, thereby causing the support assembly 310 to drive the mop 320 to rotate, thus enabling the mop 320 to work and achieve the cleaning function. When the mop 320 is working, the engagement unit 226 stops engaging with the rack 227. When the drive gear 221 rotates in reverse, the engagement unit 226 engages with the rack 227, and the cleaning mechanism 300 can move to the second position 302 or the third position 303. When the engagement unit 226 engages with the rack 227, the engagement unit 226 can drive the rack 227 to slide. When the rack 227 abuts against the base 100 and interferes with each other, the housing 210 will slide relative to the base 100, thereby causing the entire cleaning mechanism 300 to move from the first position 301 to the second position 302 or the third position 303 relative to the base 100, following the movement of the housing 210 relative to the base 100. For example, in the first position 301, the first cleaning surface 321 and the second cleaning surface 322 of the mop 320 are both located outside the receiving cavity 110, thus allowing the mop 320 to clean the first working surface and the second working surface simultaneously. In the second position 302, the first cleaning surface 321 of the mop 320 is located outside the receiving cavity 110 and the second cleaning surface 322 is located inside the receiving cavity 110, thus allowing the mop 320 to clean the first working surface but not the second working surface. In the third position 303, the first cleaning surface 321 and the second cleaning surface 322 of the mop 320 are both located in the receiving cavity 110, which makes it impossible for the mop 320 to clean the first and second working surfaces.

[0079] See Figure 3 and Figure 4In some embodiments, the base 100 is generally a cuboid structure, having a bottom surface 120, a top surface 140, and a side surface 130. The bottom surface 120 and the top surface 140 can be arranged parallel to each other, and the side surface 130 connects the bottom surface 120 and the top surface 140, such that the side surface 130 can be perpendicular to both the bottom surface 120 and the top surface 140. The bottom surface 120 faces the first working surface, the top surface 140 faces away from the first working surface, and the side surface 130 faces the second working surface. The bottom surface 120 and the top surface 140 extend horizontally and are spaced apart vertically, while the side surface 130 extends vertically. The accommodating cavity 110 has openings on both the bottom surface 120 and the side surface 130. The opening on the bottom surface 120 is designated as the first opening 121, and the opening on the side surface 130 is designated as the second opening 131. The ends of the first opening 121 and the second opening 131 are interconnected. The first cleaning surface 321 can extend or retract from the first opening 121 into the receiving cavity 110, thereby allowing the first cleaning surface 321 to switch between inside and outside the receiving cavity 110. Similarly, the second cleaning surface 322 can extend or retract from the second opening 131 into the receiving cavity 110, thereby allowing the second cleaning surface 322 to switch between inside and outside the receiving cavity 110. Of course, the receiving cavity 110 may also have an opening on its top surface 140, which would improve the ease of assembly of the cleaning mechanism 300.

[0080] See Figure 12 , Figure 13 , Figure 14 and Figure 15 In some embodiments, the meshing unit 226 includes a drive gear 2261 and a meshing gear 2262, which are interconnected and can be coaxially arranged. The drive gear 221 drives the drive gear 2261 to rotate through the transmission action of the intermediate gear, thereby causing the meshing gear 2262 to move synchronously with the drive gear 2261. The meshing gear 2262 includes a meshing portion 2262a and a tooth-deficient portion 2262b. The meshing portion 2262a has meshing teeth, while the tooth-deficient portion 2262b does not have meshing teeth. When the drive gear 221 rotates forward, the tooth-deficient portion 2262b can correspond to the rack 227, preventing the meshing portion 2262a of the meshing gear 2262 from meshing with the rack 227. Consequently, the drive gear 2261 cannot drive the rack 227 to move through the meshing gear 2262. When the drive gear 221 reverses, the meshing part 2262a corresponds to the rack 227, and the meshing part 2262a will mesh with the rack 227, so that the power gear 2261 drives the rack 227 to move through the meshing gear 2262, thereby enabling the cleaning mechanism 300 to move from the first position 301 to the second position 302 or the third position 303 relative to the base 100 with the housing 210.

[0081] See Figure 12 , Figure 13 , Figure 14 and Figure 15 In some embodiments, the engagement unit 226 further includes a one-way bearing 2263, and the engagement gear 2262 is connected to the drive gear 2261 through the one-way bearing 2263. Therefore, when the drive gear 221 rotates forward to make the mop 320 rotate and the peristaltic pump work, the engagement gear 2262 cannot transmit power to the engagement gear 2262 through the one-way bearing 2263, so that the engagement gear 2262 cannot drive the rack 227 to move; therefore, when the drive gear 221 rotates forward, the engagement gear 2262 will not be able to move, so that the engagement gear 2262 cannot drive the rack 227 to move, and consequently the cleaning mechanism 300 cannot move to the second position 302 or the third position 303. When the drive gear 221 reverses to stop the mop 320 from rotating and the peristaltic pump cannot pump water, the meshing gear 2262 can transmit power to the meshing gear 2262 through the one-way bearing 2263, causing the meshing gear 2262 to rotate. When the meshing part 2262a of the meshing gear 2262 meshes with the rack 227, the meshing gear 2262 will drive the rack 227 to move. Therefore, when the drive gear 221 reverses, the meshing gear 2262 can move, and the meshing gear 2262 will drive the rack 227 to move, thereby allowing the cleaning mechanism 300 to move to the second position 302 or the third position 303.

[0082] See Figure 12 , Figure 13 , Figure 14 and Figure 15In some embodiments, one of the housing 210 and the base 100 has a first groove 161 and the other has a guide post 213. For example, the housing 210 has a guide post 213 and the base 100 has a first groove 161. The first groove 161 extends horizontally, keeping the distance between the first groove 161 and the first cleaning surface 321 and the first working surface constant. The guide post 213 slides in engagement with the first groove 161. In the first position 301, both the first cleaning surface 321 and the second cleaning surface 322 are outside the receiving cavity 110. When the guide post 213 moves to the end of the first groove 161 away from the second opening 131, the cleaning mechanism 300 is in the second position 302. At this time, the first cleaning surface 321 is still exposed outside the receiving cavity 110 through the first opening 121, and the second cleaning surface 322 is retracted into the receiving cavity 110 through the second opening 131. Therefore, the movement trajectory of the cleaning mechanism 300 can be limited by the sliding engagement of the guide post 213 and the first slide groove 161. The base 100 may include a protrusion 150, which protrudes from the inner wall of the accommodating cavity 110. When the rack 227 abuts against the protrusion 150, the housing 210 will move relative to the base 100, thereby causing the cleaning mechanism 300 to move from the first position 301 to the second position 302 relative to the base 100 along with the housing 210.

[0083] See Figure 12 , Figure 13 , Figure 14 and Figure 15 In some embodiments, the second position 302 and the third position 303 are spaced apart. In the third position 303, both the first cleaning surface 321 and the second cleaning surface 322 are located within the receiving cavity 110, at which point the mop 320 loses its cleaning function. When the drive gear 221 reverses, the cleaning mechanism 300 can move from the first position 301 to the third position 303 via the second position 302, or the cleaning mechanism 300 can move from the first position 301 to the third position 303 without passing through the second position 302. Therefore, when the cleaning mechanism 300 is not in use, it can be moved to the third position 303, so that the housing 210 protects the mop 320. Alternatively, when the cleaning mechanism 300 passes over a blanket, it can also be moved to the third position 303, thus preventing the mop 320 from contacting the blanket and contaminating it.

[0084] See Figure 12 , Figure 13 , Figure 14 and Figure 15In some embodiments, one of the housing 210 and the base 100 is provided with a first groove 161 and a second groove 162, and the other is provided with a guide post 213. For example, the base 100 is also provided with a second groove 162, which is interconnected with the first groove 161. In the horizontal direction, the second groove 162 is further away from the second opening 131 relative to the first groove 161. The second groove 162 is inclined at an angle relative to the first cleaning surface 321 and the first working surface. From the end of the second groove 162 near the first groove 161 to the end away from the first groove 161, the distance from the second groove 162 to the first cleaning surface 321 and the first working surface can be increased. The guide post 213 slides in conjunction with the first slide groove 161 and the second slide groove 162. In the first position 301, the guide post 213 is located at the end of the first slide groove 161 furthest from the second slide groove 162. In the second position 302, the guide post 213 is located at the junction of the first slide groove 161 and the second slide groove 162. At this position, the guide post 213 can be understood as being located at either the end of the first slide groove 161 closest to the second slide groove 162, or the end of the second slide groove 162 closest to the first slide groove 161. In the third position 303, the guide post 213 is located at the end of the second slide groove 162 furthest from the first slide groove 161.

[0085] Therefore, when the cleaning mechanism 300 is in the first position 301, both the first cleaning surface 321 and the second cleaning surface 322 are outside the receiving cavity 110. When the cleaning mechanism 300 is in the second position 302, the first cleaning surface 321 is outside the receiving cavity 110, and the second cleaning surface 322 is inside the receiving cavity 110. When the cleaning mechanism 300 is in the third position 303, both the first cleaning surface 321 and the second cleaning surface 322 are inside the receiving cavity 110. It can be understood that during the process of the cleaning mechanism 300 moving from the second position 302 to the third position 303, the first cleaning surface 321 gradually moves upward, that is, the entire cleaning mechanism 300 gradually rises, thereby causing the first cleaning surface 321 to gradually retract from the first opening 121 into the receiving cavity 110. Obviously, the second cleaning surface 322 is further away from the second opening 131, so the second cleaning surface 322 is still inside the receiving cavity 110.

[0086] See Figure 12 , Figure 13 , Figure 14 and Figure 15In some embodiments, the cleaning device 10 further includes an elastic element 500 connected between the housing 210 and the base 100. When the drive gear 221 rotates forward, the elastic element 500 causes the cleaning mechanism 300 to move to the first position 301. That is, the elastic element 500 releases energy and provides power to automatically move the cleaning mechanism 300 from the second position 302 or the third position 303 to the first position 301. It can be understood that the elastic element 500 stores energy during the process of the cleaning mechanism 300 moving from the first position 301 to the second position 302 or the third position 303. The elastic element 500 can be a spring, etc. The second drive mechanism 400 also includes a sensor switch 410. A sensor switch 410 is provided on the housing 210 at locations corresponding to the first position 301, the second position 302, and the third position 303. In this case, the number of sensor switches 410 can be three. By setting the sensor switches 410, the exact position of the cleaning mechanism 300 can be known.

[0087] Therefore, when the cleaning device 10 is working, the drive gear 221 can rotate forward, which in turn causes the peristaltic gear 222 to drive the pump head 231 of the peristaltic pump to rotate forward, thus realizing the water pumping function. At this time, the telescopic member 225 will be inserted into the drive shaft 312 and form a connection with the drive shaft 312, so that the drive shaft 312 drives the mop 320 to rotate relative to the support member 311, thereby realizing the cleaning function of the mop 320. Therefore, during the cleaning process of the mop 320, the peristaltic pump will pump water into the mop 320, thereby improving the cleaning effect of the cleaning device 10. At the same time, the meshing gear 2262 will not be able to rotate, so that the cleaning mechanism 300 cannot move from the first position 301 to the second position 302 or the third position 303, thereby ensuring that the cleaning mechanism 300 cleans the first working surface and the second working surface in the first position 301.

[0088] When the cleaning device 10 needs to stop working, the drive gear 221 can be reversed, which in turn causes the peristaltic gear 222 to drive the pump head 231 of the peristaltic pump to reverse and stop the pumping function. At this time, the telescopic member 225 will disengage from the drive shaft 312 and disconnect from the drive shaft 312, so that the drive shaft 312 stops driving the mop 320 to rotate relative to the support member 311. At the same time, the power gear 2261 will drive the meshing gear 2262 to rotate, so that the meshing gear 2262 drives the rack 227 to move, which in turn causes the cleaning mechanism 300 to move from the first position 301 through the second position 302 to the third position 303.

[0089] It is understandable that when it is necessary to move the cleaning mechanism 300 from the third position 303 to the first position 301, the drive gear 221 can be reversed by a certain angle, thereby causing the meshing part 2262a of the meshing gear 2262 to disengage from the rack 227, so that the tooth-deficient part 2262b of the meshing gear 2262 corresponds to the rack 227. At this time, the meshing gear 2262 will release the holding force on the rack 227, so that the elastic element 500 releases energy and moves the cleaning mechanism 300 from the third position 303 to the first position 301 via the second position 302.

[0090] In some embodiments, the second drive mechanism 400 further includes a water pump 230 disposed within the housing 210. The drive assembly 220 is also used to drive the support assembly 310 on the cleaning mechanism 300 to rotate the mop 320, and to drive the water pump 230 to pump water to the mop 320, thereby keeping the mop 320 in a wet state and improving the cleaning effect of the mop 320.

[0091] This application also provides a cleaning robot, which includes a main unit and the aforementioned cleaning device 10. The base 100 of the cleaning device 10 is disposed on the main unit, thereby realizing the assembly of the cleaning device 10 and the main unit. By including the cleaning device 10 in the cleaning robot, the cleaning effect and ease of use of the cleaning robot can be improved.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
