DETAILED DESCRIPTION OF THE INVENTION

[0029] In order to clarify the objectives, technical solutions and advantages of the present disclosure, the present disclosure will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments of the present disclosure, other embodiments that can be obtained by those skilled in the art without any creative work are all included in the protection scope of the present disclosure.

[0030] The terms used in the embodiments of the present disclosure are used only for the purpose of describing particular embodiments and are not intended to limit the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" are also intended to encompass the plural form unless the context clearly dictates otherwise, and "plurality" generally includes at least two.

[0031] It should be understood that the term "and / or" used herein merely describes the relation between related objects, and for example, A and / or B can have three possibilities: A alone, both A and B, or B alone. Furthermore, in this specification, " / " generally indicates that the related objects before and after it are in an "or" relation.

[0032] It should be understood that, although the embodiments of the present disclosure are described using terms such as first, second, and third, these terms are not intended to be limiting. These terms are used for distinction purposes only. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of the embodiments of the present disclosure.

[0033] It should be noted that the terms "comprises," "has," or any other variation thereof are intended to cover a non-exclusive inclusion, and a product or device comprising a set of elements includes not only those elements but also other elements not expressly listed or inherent in such product or device. Unless further qualified, the fact that a definition is made with the phrase "comprising one of..." does not exclude the presence of other elements of the same type in the product or device of said element.

[0034] Alternative embodiments of the present disclosure will now be described with reference to the accompanying drawings.

[0035] 1 and 2 are structural schematic diagrams of an automatic cleaning device according to an exemplary embodiment. As shown in FIGS. 1 and 2, the automatic cleaning device may be a vacuum ground suction robot, a mop / brush robot, a window climbing robot, etc., and the automatic cleaning device may include a moving platform 100, a sensing system 120, a control system 130, a drive system 140, a cleaning module 150, an energy system 160 and a human interaction system 170.

[0036] The mobile platform 100 may be configured to automatically move along a target direction on an operating surface. The operating surface may be a surface to be cleaned by an automatic cleaning device. In some embodiments, the automatic cleaning device may be a mopping robot, where the automatic cleaning device operates on a floor surface, with the floor surface being the operating surface; a window cleaning robot, where the automatic cleaning device operates on the glass exterior surface of a building, with the glass being the operating surface; or a pipe cleaning robot, where the automatic cleaning device operates on the interior surface of a pipe, with the interior surface of the pipe being the operating surface. For illustrative purposes only, the following description will use a mopping robot as an example.

[0037] In some embodiments, mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. An autonomous mobile platform means that mobile platform 100 itself automatically and adaptively makes operational decisions in response to unexpected environmental inputs. A non-autonomous mobile platform cannot make operational decisions in response to unexpected environmental inputs, but can operate according to a predetermined program or logic. Therefore, if mobile platform 100 is an autonomous mobile platform, the target direction may be determined autonomously by an automatic cleaning device. If mobile platform 100 is a non-autonomous mobile platform, the target direction may be set by a system or manually. If mobile platform 100 is an autonomous mobile platform, mobile platform 100 includes a front portion 111 and a rear portion 110.

[0038] The sensing system 120 includes a positioning device 121 located above the mobile platform 100, a buffer 122 located in the front portion 111 of the mobile platform 100, a cliff sensor 123 located at the bottom of the mobile platform, and sensing devices such as ultrasonic sensors (not shown), infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), and odometers (not shown), and provides the control system 130 with information on the position and movement status of the equipment.

[0039] To more clearly explain the operation of the automatic cleaning device, the following directions are defined: the automatic cleaning device can move on the ground by various combinations of motion about three mutually perpendicular axes defined by the mobile platform 100: the horizontal axis x, the front-to-rear axis y, and the central vertical axis z. The forward driving direction along the front-to-rear axis y is defined as "forward," and the rear driving direction along the front-to-rear axis y is defined as "rear." The horizontal axis x is approximately aligned with the axis defined by the center point of the drive wheel assembly 141 extending between the right and left wheels of the automatic cleaning device. Here, the automatic cleaning device may rotate about the x-axis. When the front part of the automatic cleaning device tilts upward and the rear part tilts downward, this is referred to as "pitch up," and when the front part of the automatic cleaning device tilts downward and the rear part tilts upward, this is referred to as "pitch down." Furthermore, the automatic cleaning device may rotate about the z-axis. When the automatic cleaning device tilts to the right of the y-axis in the forward direction of the automatic cleaning device, this is referred to as "right turn," and when the automatic cleaning device tilts to the left of the y-axis, this is referred to as "left turn."

[0040] 2, cliff sensors 123 are provided at the bottom of the moving platform 100, in front of and behind the drive wheel assembly 141, to prevent the automatic cleaning device from falling when retreating, thereby preventing damage to the automatic cleaning device. The "front" refers to the same side as the traveling direction of the automatic cleaning device, and the "rear" refers to the opposite side to the traveling direction of the automatic cleaning device.

[0041] The position determining device 121 includes, but is not limited to, a camera, a laser distance sensor (LDS).

[0042] Each assembly in the sensing system 120 may be independent or may work together to more accurately achieve its intended function. The cliff sensor 123 and ultrasonic sensor recognize the cleaning surface and determine the physical properties of the cleaning surface (including surface material, cleanliness, etc.), which can be combined with cameras, laser distance measuring devices, etc. to make more accurate determinations.

[0043] For example, an ultrasonic sensor can determine whether the surface to be cleaned is carpet, and if the ultrasonic sensor determines that the surface to be cleaned is carpet material, the control system 130 controls the automatic cleaning device to clean in carpet mode.

[0044] A buffer 122 is provided on the front part 111 of the mobile platform 100, and during the cleaning process, the drive wheel assembly 141 propels the automatic cleaning device to travel on the floor surface. The buffer 122 detects one or more events (or objects) in the travel path of the automatic cleaning device via a sensor system, for example, an infrared sensor, and the automatic cleaning device controls the drive wheel assembly 141 based on the events (or objects), for example, an obstacle or a wall, detected by the buffer 122 so that the automatic cleaning device responds to the event (or object) and, for example, moves away from the obstacle.

[0045] The control system 130 is provided on a circuit motherboard within the mobile platform 100 and includes an arithmetic processor, such as a central processing unit or an application processor, communicating with a non-transitory memory, such as a hard disk, flash memory, or random access memory. The application processor receives environmental information sensed by the multiple sensors from the sensing system 120, obstacle information fed back from the laser distance measuring device, etc., uses a positioning algorithm, such as SLAM, to draw an instantaneous map of the environment in which the automatic cleaning device is located, autonomously determines a travel path based on the environmental information and the environmental map, and then performs operations such as moving forward, backward, and / or steering the drive system 140 based on the autonomously determined travel path. Furthermore, the control system 130 determines whether to operate the cleaning module 150 to perform a cleaning operation based on the environmental information and the environmental map.

[0046] Specifically, the control system 130 combines distance and speed information fed back from sensing devices such as the buffer 122, cliff sensor 123, and ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current operating state of the vacuum cleaner, such as whether it has crossed a threshold, is on a carpet, is on a cliff, is stuck above or below, has a full dustbin, or is being lifted, or provides specific next operating strategies according to different situations, allowing the operation of the automatic cleaning device to better meet the owner's needs and providing a better user experience. Furthermore, the control system can plan the most efficient and rational cleaning path and cleaning method based on the instant map information drawn by SLAM, significantly improving the cleaning efficiency of the automatic cleaning device.

[0047] Based on specific distance and angle information, such as x, y, and θ components, the drive system 140 executes drive commands to drive the automatic cleaning device to move across the floor surface. As shown in FIG. 2 , the drive system 140 includes a drive wheel assembly 141. The drive system 140 may simultaneously control the left and right wheels. For more precise control of the movement of the device, the drive system 140 may include a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are symmetrically arranged along a horizontal axis defined by the mobile platform 100.

[0048] In order for the automatic cleaning device to move more stably on the floor surface or have higher mobility, the automatic cleaning device may include one or more steering assemblies 142, and the steering assembly 142 may be a driven wheel or a driving wheel, and its structural form includes, but is not limited to, a universal wheel, and the steering assembly 142 may be located in front of the driving wheel assembly 141.

[0049] The drive motor 146 provides power to rotate the drive wheel assembly 141 and / or the steering assembly 142 .

[0050] The drive wheel assembly 141 may be detachably connected to the mobile platform 100 for easy installation, removal, and maintenance. The drive wheel may include an offset drop suspension system and may be movably fixed, e.g., rotatably assembled to the automatic cleaning device mobile platform 100, and maintain contact and traction with the floor surface with a constant ground force by means of an elastic element such as a tension spring or compression spring, while the cleaning module 150 of the automatic cleaning device also contacts the surface to be cleaned with a constant pressure.

[0051] The energy system 160 may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery is connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery low voltage monitoring circuit, which are all connected to a single-chip microcomputer control circuit. The host is connected to the charging pile via charging electrodes located on the side or bottom of the device for charging. If dust adheres to the exposed charging electrodes, the resin around the electrodes will melt and deform due to the charge accumulation effect during charging, and the electrodes themselves will also deform, preventing normal charging.

[0052] The human interaction system 170 may include buttons on the host panel, which are used by the user to select functions, a display screen, and / or indicator lights and / or a speaker, which are used to display the current status or function options of the device to the user, and a mobile phone client program. In the case of a route navigation type cleaning device, the mobile phone client can display a map of the device's environment and the device's location to the user, thereby providing the user with more abundant and user-friendly function items.

[0053] The cleaning module 150 includes a dry cleaning module 151 and / or a wet cleaning module 400 .

[0054] As shown in Figure 2, the dry cleaning module 151 includes a roller brush, a dust box, a fan, and an air outlet. The roller brush, which has a certain degree of interference with the floor, sweeps up dust on the floor and lifts it up in front of the dust suction port between the roller brush and the dust box. The dust is then sucked into the dust box by the suction gas generated by the fan and passing through the dust box. The dust removal capacity of a vacuum cleaner is expressed in terms of the dust pickup efficiency (DPU). The DPU is affected by the structure and material of the roller brush, the wind power utilization rate of the airflow path consisting of the dust suction port, dust box, fan, air outlet, and the connecting components between these four components, and the type and output of the fan, making it a complex system design issue. Compared to a typical plug-in vacuum cleaner, improved dust removal capacity is more meaningful for energy-limited automatic cleaning devices. Furthermore, improved dust removal capacity directly and effectively reduces energy requirements; i.e., a device that can clean 80 square meters of floor space on a single charge can be improved to clean more than 180 square meters on a single charge. Battery life is also significantly extended, reducing the number of charges, potentially reducing the frequency with which users need to replace batteries. More intuitively and importantly, improved dust removal capacity provides the most obvious and meaningful user experience, allowing users to directly conclude whether thorough cleaning / mopping has been achieved. The dry cleaning module further includes a side brush 152 with a rotating shaft that is angled relative to the floor surface and moves debris to the roller brush area of ​​the cleaning module 150.

[0055] According to a specific embodiment of the present disclosure, as shown in Figures 3 to 5, the present disclosure provides a wet cleaning module 400 for cleaning at least a portion of the operating surface by wet cleaning, wherein the wet cleaning module 400 includes a cleaning head 410 and a drive unit 420, wherein the cleaning head 410 is used to clean at least a portion of the operating surface, and the drive unit 420 drives the cleaning head 410 to move approximately back and forth along a target surface, which is a portion of the operating surface. The cleaning head 410 moves back and forth along the surface to be cleaned, and a cleaning cloth or cleaning plate is provided on a surface that contacts the cleaning head 410 and the surface to be cleaned, and the back and forth movement generates high-frequency friction with the surface to be cleaned, thereby removing dirt from the surface to be cleaned.

[0056] The higher the friction frequency, the more friction times per unit time. High-frequency reciprocating motion, also known as reciprocating vibration, has a much higher cleaning ability than ordinary reciprocating motion, such as rotational or frictional cleaning. Optionally, the friction frequency is similar to that of sound waves, and the cleaning effect is much better than that of rotational frictional cleaning with several tens of turns per minute. Meanwhile, the tufts on the surface of the cleaning head are more aligned and spread in the same direction due to high-frequency vibration, resulting in a more uniform cleaning effect overall. Unlike the low-frequency rotation, which increases frictional force solely through downward pressure, the tufts do not spread in the same direction due to downward pressure alone. As a result, after high-frequency vibration cleaning, the water marks on the operating surface are more uniform and no chaotic water stains remain.

[0057] The reciprocating motion may be repeated movement along any one or more directions within the operating surface, or vibration perpendicular to the operating surface, but is not strictly limited to this. Alternatively, the cleaning module's reciprocating motion may be approximately perpendicular to the device's direction of travel. Reciprocating motion parallel to the device's direction of travel can cause the device itself to become unstable during operation. The thrust and resistance in the direction of travel can easily cause the drive wheels to skid. The effects of skidding are even more pronounced when a wet cleaning module is included, and a wet operating surface increases the likelihood of skidding. Skidding not only affects the device's ability to clean reliably, but also leads to inaccurate distance measurements by sensors such as odometers and gyroscopes, preventing navigation-based automatic cleaning devices from accurately positioning and mapping. Frequent skidding can also have a significant impact on SLAM (Slide-Away Tracking). Therefore, skidding must be prevented as much as possible. In addition to skidding, the cleaning head's movement in the device's direction of travel can constantly push the device back and forth, resulting in unstable operation.

[0058] As an embodiment of the present disclosure, as shown in FIG. 3, the drive unit 420 includes a drive platform 421 connected to the bottom surface of the moving platform 100 and configured to provide a driving force, and a support platform 422 detachably connected to the drive platform 421, supporting the cleaning head 410, and configured to be driven by the drive platform 421 to move up and down.

[0059] In an embodiment of the present disclosure, a lifting module is provided between the cleaning module 150 and the mobile platform 100, configured to allow the cleaning module 150 to make better contact with the surface to be cleaned or to use different cleaning strategies for surfaces of different materials to be cleaned.

[0060] In an embodiment of the present disclosure, the dry cleaning module 151 may be connected to the mobile platform 100 via a passive lifting module, so that when the cleaning device encounters an obstacle, the dry cleaning module 151 can more easily overcome the obstacle via the lifting module.

[0061] In an embodiment of the present disclosure, the wet cleaning module 400 is connected to the moving platform 100 via an active lifting module, and when the wet cleaning module 400 is temporarily not working or the surface to be cleaned cannot be cleaned by the wet cleaning module 400, the active lifting module lifts the wet cleaning module 400 and separates it from the surface to be cleaned to realize a change of cleaning means.

[0062] As shown in Figures 4 and 5, the driving platform 421 includes a motor 4211 that is located on the side of the driving platform 421 closer to the moving platform 100 and outputs power through a motor output shaft, a driving wheel 4212 that is connected to the motor output shaft and has an asymmetric structure, and a vibration member 4213 that is located on the opposite side of the driving platform 421 from the motor 4211, connected to the driving wheel 4212, and moves back and forth under the asymmetric rotation of the driving wheel 4212.

[0063] The drive platform 421 may further include a gear mechanism. The gear mechanism may connect the motor 4211 and the drive wheel 4212. The motor 4211 may directly drive the pivoting movement of the drive wheel 4212, or may indirectly drive the pivoting movement of the drive wheel 4212 via the gear mechanism. Those skilled in the art will understand that the gear mechanism may be a single gear or a gear set consisting of multiple gears.

[0064] The motor 4211 simultaneously transmits power to the cleaning head 410, the driving platform 421, the support platform 422, the water supply mechanism, the liquid storage tank, etc. through a power transmission device. The energy system 160 provides power and energy to the motor 4211 and is entirely controlled by the control system 130. The power transmission device may be a gear transmission, a chain transmission, a belt transmission, a worm gear, etc.

[0065] The motor 4211 has a forward output mode and a reverse output mode, in which the motor 4211 rotates forward, and in which the motor 4211 rotates reverse. In the forward output mode of the motor 4211, the motor 4211 moves the vibration member 4213 of the drive platform in the wet cleaning assembly 400 approximately back and forth through a power transmission device, and drives the water supply mechanism to move synchronously. In the reverse output mode of the motor 4211, the motor 4211 drives the platform 421 to rise and fall through a power transmission device.

[0066] Furthermore, the drive platform 421 further includes a connecting rod 4214 extending along the edge of the drive platform 421, connecting the drive wheel 4212 and the vibration member 4213, and configured to extend the vibration member 4213 to a predetermined position, wherein the extension direction of the vibration member 4213 is perpendicular to the connecting rod 4214, and the reciprocating movement direction of the vibration member 4213 is approximately perpendicular to the equipment travel direction.

[0067] The motor 4211 is connected to the driving wheel 4212, the vibration member 4213, the connecting rod 4214, and the vibration damping device 4215 via a power transmission device. Here, the vibration member 4213 and the connecting rod 4214 form a substantially L-shaped structure, and as shown in FIG. 6 , the vibration member 4213 is driven by the connecting rod 4214 to move back and forth. The vibration damping device 4215 has the function of reducing vibration and jitter caused by the movement caused by the driving wheel 4212, and allows the vibration member 4213 to stably vibrate within the movement range that can be provided by the support platform 422. Optionally, the vibration damping device 4215 is made of a flexible material, preferably a rubber structure, and the vibration damping device 4215 is fitted to the connecting rod 4214. On the other hand, the vibration damping device 4215 can protect the vibration member 4213 from damage caused by collision with the driving platform 421, thereby affecting the reciprocating movement of the vibration member 4213. The movable and fixed members of the drive platform 421 are connected in a less elastic manner to restrict movement in the direction of travel of the device, but are connected in a more flexible manner to permit movement in a direction substantially perpendicular to the direction of travel, i.e., the vibration direction of the vibrating member 4213. Due to the restriction on movement of both members, the vibrating member 4213 does not move precisely back and forth, but rather moves approximately back and forth. When the wet cleaning assembly 400 is started, the motor 4211 starts rotating forward, and the motor 4211 drives the connecting rod 4214 via the drive wheel 4212 to move back and forth along the surface of the drive platform 421. At the same time, the vibration damper 4215 drives the vibrating member 4213 to move approximately back and forth along the surface of the drive platform 421, and the vibrating member 4213 drives the cleaning substrate 4221 to move approximately back and forth along the surface of the support platform 422, which in turn drives the cleaning substrate 4221 to move approximately back and forth in the active area 412 along the surface to be cleaned. At this time, the clean water pump causes clean water to flow out of the liquid storage tank and through the water discharge device 4217 to spray the clean water onto the cleaning head 410, which then moves back and forth to clean the surface to be cleaned.

[0068] The cleaning intensity / efficiency of the automatic cleaning device can be automatically and dynamically adjusted according to the working environment of the automatic cleaning device. For example, the automatic cleaning device can dynamically adjust based on physical information of the surface to be cleaned detected by the sensing system 120. For example, the sensing system 120 may detect information such as the flatness of the surface to be cleaned, the material of the surface to be cleaned, and the presence or absence of oil or dust, and transmit this information to the control system 130 of the automatic cleaning device. In response to this, the control system 130 can automatically and dynamically adjust the rotation speed of the motor and the transmission ratio of the power transmission device according to the working environment of the automatic cleaning device, and control the automatic cleaning device to adjust the preset reciprocating period of the reciprocating movement of the cleaning head 410.

[0069] For example, when the automatic cleaning device works on a flat floor surface, the preset reciprocating period may be automatically and dynamically adjusted to be longer and the amount of water of the water pump may be automatically and dynamically adjusted to be smaller, and when the automatic cleaning device works on an uneven floor surface, the preset reciprocating period may be automatically and dynamically adjusted to be shorter and the amount of water of the water pump may be automatically and dynamically adjusted to be larger. This is because it is easier to clean a flat floor surface than an uneven floor surface, and therefore faster reciprocating movement (i.e., higher frequency) of the cleaning head 410 and a larger amount of water are required to clean an uneven floor surface.

[0070] For example, when the automatic cleaning device 100 works on a table, the preset reciprocating period may be automatically and dynamically adjusted to be longer and the amount of water flowing from the water pump may be automatically and dynamically adjusted to be smaller, and when the automatic cleaning device 100 works on a floor, the preset reciprocating period may be automatically and dynamically adjusted to be shorter and the amount of water flowing from the water pump may be automatically and dynamically adjusted to be larger. This is because there is less dust and oil on a table than on a floor, and the table material is easier to clean, so the table can be cleaned with fewer reciprocating movements of the cleaning head 410 and a smaller amount of water flowing from the water pump.

[0071] In an embodiment of the present disclosure, the support platform 422 includes a cleaning substrate 4221 movably mounted on the support platform 422, and the cleaning substrate 4221 moves approximately back and forth under the vibration of the vibrating member 4213. In an embodiment of the present disclosure, as shown in Fig. 7, the cleaning substrate 4221 includes an assembly notch 42211 provided at a position where it contacts the vibrating member 4213, and when the support platform 422 is connected to the driving platform 421, the vibrating member 4213 is assembled to the assembly notch 42211, and the cleaning substrate 4221 moves approximately back and forth synchronously with the vibrating member 4213. The cleaning substrate 4221 includes four first limiting positions 42212 in the direction of travel of the cleaning device, which are flexibly connected to the cleaning substrate 4221 and have a small elastic scaling space, thereby limiting the movement of the cleaning substrate 4221 relative to the support platform 422 in the direction of travel of the cleaning device. The cleaning substrate 4221 also includes two second limiting positions 42213 in a direction perpendicular to the direction of travel of the cleaning device, which limit the range of reciprocating movement of the cleaning substrate 4221 in the direction perpendicular to the direction of travel of the cleaning device. Furthermore, a water discharge hole 42214 is provided near the assembly notch 42211 of the cleaning substrate 4221, through which water flowing out from the water discharge device 4217 flows to the cleaning head 410. Due to the influence of the limiting positions and the vibration damping device, the movement of the cleaning substrate 4221 is essentially reciprocating. The cleaning substrate 4221 is located at a portion of the support platform 422, and the local vibrations can cause the vibration frequency to increase, for example, to reach the sonic frequency range. The movable and fixed members of the drive platform 421 are connected in a flexible manner to restrict movement in the direction of travel of the device, but are allowed to move in a direction approximately perpendicular to the direction of travel, i.e., in the vibration direction of the vibrating member 4213, by being connected in a flexible manner.

[0072] Further, the support platform 422 further includes an elastic release button 4229, which is disposed on at least one side of the support platform 422, and which detachably connects the support platform 422 to the engaging claws 4216 of the drive platform 421, so that the support platform 422 is detachably mechanically fixed to the drive platform 421 and fixed to the drive platform and the automatic cleaning device. At least one assembly area 4224 is disposed on the support platform 422 for assembling the cleaning head 410. The assembly area 4224 is formed of an adhesive material having an adhesive layer.

[0073] 3, the cleaning head 410 includes a movable region 412 connected to the cleaning substrate 4221 and adapted to move approximately back and forth along the cleaning surface under the driving force of the cleaning substrate 4221. The movable region 412 is disposed at approximately the center of the cleaning head 410.

[0074] In the embodiment of the present disclosure, an adhesive layer is provided on the side of the movable region 412 connected to the cleaning substrate 4221, and the movable region 412 and the cleaning substrate 4221 are connected via the adhesive layer.

[0075] In an embodiment of the present disclosure, the cleaning head 410 includes a fixed area 411 connected to the bottom of the support platform 422 via the at least one assembly area 4224, and the fixed area 411 cleans at least a portion of the operating surface according to the movement of the support platform 422.

[0076] Furthermore, the cleaning head 410 includes a flexible connection 413 provided between the fixed region 411 and the movable region 412 for connecting the fixed region 411 and the movable region 412. The cleaning head 410 further includes a sliding buckle 414 extending along an edge of the cleaning head 410 and removably attached to an engagement position 4225 of the support platform 422.

[0077] In this embodiment, as shown in Figure 3, the cleaning head 410 is made of a material with a certain degree of elasticity, and is fixed to the surface of the support platform 422 via an adhesive layer to achieve reciprocating movement. When the cleaning head 410 works, the cleaning head 410 is always in contact with the surface to be cleaned.

[0078] The water supply mechanism includes a water discharge device 4217, which is directly or indirectly connected to a cleaning liquid outlet of a liquid storage tank (not shown), i.e., a liquid outlet of the liquid storage tank, where the cleaning liquid flows to the water discharge device 4217 through the cleaning liquid outlet of the liquid storage tank and can be evenly applied to the surface to be cleaned by the water discharge device. A connecting member (not shown) is provided on the water discharge device, and the water discharge device is connected to the cleaning liquid outlet of the liquid storage tank through the connecting member. The water discharge device is provided with a distribution port, which can be a continuous opening or a combination of multiple discontinuous small openings, or the distribution port can be provided with multiple nozzles. The cleaning liquid flows to the distribution port via the cleaning liquid outlet of the liquid storage tank and the connecting member of the water discharge device, and can be evenly applied to the operating surface through the distribution port.

[0079] The water delivery mechanism further includes a clean water pump 4219 and / or a clean water pump pipe 4218, which may be directly connected to the cleaning liquid outlet of the liquid storage tank or may be connected via the clean water pump pipe 4218.

[0080] The clean water pump 4219 may be connected to the connecting member of the water dispensing device and configured to suck the cleaning liquid from the liquid storage tank and pump it to the water dispensing device. The clean water pump may be a gear pump, a vane pump, a plunger pump, a peristaltic pump, etc.

[0081] The water supply mechanism sucks the cleaning liquid from the liquid storage tank via the clean water pump 4219 and the clean water pump pipe 4218 and transports it to the water discharge device. The water discharge device 4217 may be a sprinkler head, drip hole, wet cloth, etc., and distributes water evenly over the cleaning head, wetting the cleaning head and the surface to be cleaned. After wetting, dirt on the surface to be cleaned can be more easily removed. In the wet cleaning assembly 400, the output / flow rate of the clean water pump may be adjusted.

[0082] Furthermore, as shown in FIG. 8, the motor 4211 drives the clean water pump 4219 to move peristally via the gear set 42193, and the peristaltic movement of the clean water pump 4219 causes clean water to enter through the water inlet 42191, flow out through the water outlet 42192, and be transported to the water discharge device 4217 via the clean water pump pipe 4218. The water flowing out of the water discharge device 4217 flows to the cleaning head 410 via the water outlet hole.

[0083] 9, the motor 4211 drives the cable gear 42196 to rotate via the gear set 42193, the cable 42194 is wound around the cable gear 42196, the cable 42194 is wound around the drive platform 421, and the cable gear 42196 raises and lowers the cable 42194, thereby pulling the cable 42194 and raising and lowering the drive platform 421. The cable gear 42196 and the cable 42194 are the core components of the lifting module.

[0084] A clutch 42195 is provided between the gear set 42193 and the cable gear 42196. The clutch 42195 includes a spring and a sheet-like member. By controlling the clutch 42195, the motor 4211 controls the three moving modules, rotating in one direction to drive the vibration of the vibration member and simultaneously realizing the water supply of the clean water pump 4219, and rotating in the opposite direction to drive the lifting module via the cable 42194. Optionally, the combination design of the gear set can control different combinations of the three moving modules, for example, rotating in one direction to allow the clean water pump to supply water and rotating in the opposite direction to realize the lifting and vibration control. Optionally, two motors can be used to control the three moving modules, but adding motors increases costs.

[0085] The cleaning module of the automatic cleaning device includes a dry cleaning module and a wet cleaning module, which can provide more complete cleaning functions. At the same time, the wet cleaning module also includes a drive unit and a vibration area, allowing the cleaning head to move back and forth and repeatedly clean the surface to be cleaned. This allows the cleaning robot to clean multiple times while passing through an area only once, greatly improving the cleaning effect, especially in heavily soiled areas.

[0086] In cooperation with a sensor that can detect the surface type of the surface to be cleaned, such as a surface media sensor, the lifting module can perform cleaning operations according to different surfaces to be cleaned, for example, for carpet surfaces, the wet cleaning module can be lifted and the wet cleaning module can be lowered to clean surfaces such as floors / floor tiles, thereby achieving a more complete cleaning effect.

[0087] In an embodiment of the present disclosure, the automatic cleaning device 10 includes a liquid storage tank 3000, and the liquid storage tank 3000 further has a liquid refill port 3005. As shown in Figures 10 to 12, the liquid refill port 3005 may be provided on the side wall of the liquid storage tank 3000. When the automatic cleaning device 10 stops at the base station, the base station can inject cleaning liquid into the liquid storage tank 3000 of the automatic cleaning device 10 through the liquid refill port 3005.

[0088] 11 , the liquid storage tank 3000 is provided with a second assembly 3004, which is connected to a base station, so that the base station injects cleaning liquid into the liquid storage tank 3000 of the automatic cleaning device 10 through the liquid refill port 3005. The second assembly 3004 further includes a liquid refill port 3005 disposed at a substantially central position of the second assembly 3004 and configured to inject cleaning liquid into the liquid storage tank 3000.

[0089] 12 , a valve 17 is provided at the liquid refill port 3005 of the liquid storage tank 300, and the valve 17 is openable and closable, allowing control of communication between the liquid refill port 3005 and the liquid storage tank 3000. A pipe 18 is provided in the liquid storage tank 3000, and the valve 17 is provided at one end of the pipe 18.

[0090] In an embodiment of the present disclosure, the valve 17 may be an electronic valve or a manual valve, and may be opened or closed by corresponding control. In another embodiment of the present disclosure, the valve 17 may be a check valve, and after the liquid refilling of the liquid storage tank 3000 is completed and the liquid refilling port 3005 is disconnected from the liquid storage tank 3000, the valve 17 may be automatically closed to prevent the cleaning liquid in the liquid storage tank 3000 from leaking out. For example, the valve 17 may be a cross valve, a lift-up check valve, a swing check valve, etc.

[0091] In an embodiment of the present disclosure, as shown in Figures 13 to 16, the automatic cleaning device 10 includes a liquid storage tank assembly structure 4000, and the liquid storage tank 3000 includes a cutout portion 3006 that aligns with the liquid storage tank assembly structure 4000, and when the liquid storage tank 3000 is assembled to the automatic cleaning device 10, the liquid storage tank assembly structure 4000 is assembled to the cutout portion 3006 to achieve perfect alignment.

[0092] 13 and 14, the liquid storage tank assembly structure 4000 includes a tab 4001 configured to abut and engage with the boss 2002 of the button structure 12. The liquid storage tank assembly structure 4000 further includes a second elastic member 4004, which provides a vertical elastic force so that the tab 4001 moves in an expanding and contracting direction along the vertical direction, and the second elastic member 4004 and the tab 4001 are arranged in the same slide to achieve the expanding and contracting movement, and the second elastic member 4004 may be, for example, a coil spring.

[0093] In the embodiment of the present disclosure, the tab 4001 has an inclined surface 4002, and after the tab 4001 and the boss are abutted, the inclined surface 4002 is fitted to the inclined surface of the boss and locked. The tab 4001 further has a vertical surface 4003, and when the liquid storage tank is assembled to the automatic cleaning device, the vertical surface 4003 is locked to the inner surface of the groove 3002. The inclined surface 4002 and the vertical surface 4003 ensure that the liquid storage tank 3000 is accurately positioned forward and backward after being attached to the automatic cleaning device, and can avoid displacement in any direction.

[0094] 11 , liquid storage tank 3000 includes a first assembly part 3001, which is located approximately at the center of liquid storage tank 3000 and may have a rectangular, circular, or other structure, but is not limited thereto. First assembly part 3001 includes button structure 12, a groove 3002, and a light transmission hole 3003. Here, groove 3002 is located at the bottom of first assembly part 3001 and is recessed downward to form a shape that fits button structure 12. When button structure 12 is assembled to liquid storage tank 3000, groove 3002 is used to accommodate button structure 12.

[0095] As shown in Figures 15 and 16, when the button structure 12 is assembled to the first assembly part 3001 of the liquid storage tank, the liquid storage tank is assembled so as to be detachable from the automatic cleaning device. The button structure has an approximately sheet-like structure and includes a rectangular and roughly flat button body 2000, and a pressing part 2001 located at one end of the button body 2000, which, when subjected to a downward acting force, unlocks the liquid storage tank from the automatic cleaning device, making it detachable from the automatic cleaning device. The pressing part 2001 has an edge that is wider than that of the button body 2000, which is convenient for applying pressure. For example, the pressing part 2001 may have a fan-shaped structure, and protruding edges are provided on the outer edge and both side edges of the pressing part 2001, which prevent skidding when pressed and also have the effect of shielding the internal structure of the water tank. After the liquid storage tank is unlocked from the automatic cleaning device, the liquid storage tank can be completely removed from the automatic cleaning device by pulling outward the protruding edge on the outer edge of the pressing part 2001.

[0096] The button structure further includes a boss 2002 provided at one end of the button body 2000 opposite the pressing portion 2001. When the button structure 12 is assembled to the liquid storage tank 3000, the pressing portion 2001 is higher than the boss 2002 under the natural state of the first elastic member, thereby increasing the movable stroke of the pressing portion 2001 and the boss 2002. This contributes to stably attaching the liquid storage tank, making it less likely to fall off, and effectively unlocking the tab when removal is required. The boss 2002 and the pressing portion 2001 move in opposite directions, creating a seesaw effect. Compared to a system in which the boss and the pressing portion move in the same direction, the movable stroke of the boss is further increased, making it easier to detachably assemble the liquid storage tank to the automatic cleaning device.

[0097] 15 , in an embodiment of the present disclosure, the boss 2002 has a first surface 20021, which is a curved surface extending upward along the upper surface of the button body 2000, a second surface 20022, which is a curved surface smoothly connected to the first surface 20021 and configured to abut and engage with the tab of the automatic cleaning device, and a third surface 20023, which is a flat surface smoothly connected to the second surface 20022 and extends approximately vertically, where the third surface is in close contact with the flat surface of the inner surface of the groove and, together with the flat surface of the tab, achieves stable engagement of the three planes. Here, the second surface 20022 may be a recessed multi-radius curved surface that cooperates with the end and inclined surface of the tab to achieve stable engagement.

[0098] In the embodiment of the present disclosure, the connection portion between the first surface 20021 and the second surface 20022 is higher than the connection portion between the second surface 20022 and the third surface 20023, which ensures that the tab does not slide back and forth when it contacts the second surface, thereby realizing stable locking.

[0099] 15 , the button structure further includes lugs 2003 symmetrically provided on both sides of the button body 2000, and a rotation axis 2004 connecting the lugs 2003 and the liquid storage tank, the button structure being configured to rotate around the rotation axis 2004. Here, the rotation axis 2004 may be provided closer to the pressing portion 2001, so that when the button structure realizes seesaw movement via the rotation axis, the boss has a longer movable stroke than the pressing portion, and therefore the tab can be more easily jacked up via the boss, making it easier to attach and detach the liquid storage tank.

[0100] 13 , the button structure further includes a first elastic member 2005, which is provided on the underside of the pressing portion 2001 and configured to provide a restoring force to the pressing portion 2001 when the force applied to the pressing portion 2001 is released. The first elastic member 2005 may be, for example, a coil spring.

[0101] 14 , in the embodiment of the present disclosure, the upper surface of the pressing part 2001 is higher than the upper surface of the button body 2000, and the lower surface of the pressing part 2001 is higher than the lower surface of the button body 2000. This provides more movement space for the pressing part 2001, ensures a movement stroke of the pressing part 2001, and makes it easier to remove the liquid storage tank.

[0102] In an embodiment of the present disclosure, as shown in FIG. 16, a plurality of reinforcing ribs are provided on the underside of the pressing portion 2001 and / or a plurality of reinforcing ribs are provided on the underside of the button body 2000, which can increase the rigidity of the button structure while reducing the overall weight of the button structure.

[0103] 13 , in the embodiment of the present disclosure, the groove 3002 includes a groove wall 30021, and after the button structure 12 is assembled into the groove 3002, the boss 2002 has a height lower than that of the groove wall 30021 under the bias of the tab 4001, so that the tab 4001 can abut against the top end of the boss 2002 and be locked into the groove wall 30021. Furthermore, shaft holes (not shown) are provided on both side walls of the groove 3002 for inserting and rotating the rotating shaft of the button structure.

[0104] When the liquid storage tank is placed on the automatic cleaning device, the tab 4001 first compresses the spring under the pressure of the liquid storage tank, moving upward. When it reaches the groove position, the tab 4001 extends downward under the action of the spring, sliding from the inclined surface 4002 into the groove 3002. The end of the tab then abuts against the second surface 20022 of the boss. At the same time, the vertical surface 4003 of the tab contacts and engages with the inner surface of the groove wall 30021, and the third surface 20023 of the boss 2002 also abuts and engages with the inner surface of the groove wall 30021, thereby firmly fixing the liquid storage tank to the automatic cleaning device. When it is necessary to remove the liquid storage tank, the pressing plate is pressed, and the boss is lifted upward under the action of the rotating shaft, pushing up the tab. At this time, the rear end of the tab no longer contacts the groove side wall, allowing the liquid storage tank to be removed.

[0105] In an embodiment of the present disclosure, as shown in FIG. 11 , the first assembly part 3001 further includes a light transmitting opening 3003 located above the button structure 12, and the light transmitting opening 3003 is aligned with the pile return lamp position on the automatic cleaning device, and the pile return lamp emits light through the light transmitting opening 3003 to realize communication with the charging pile.

[0106] The button structure provided by the embodiment of the present disclosure is a sheet-like structure with a small volume, which increases the volume of the liquid storage tank and makes it easy to control the removal of the liquid storage tank while occupying a small volume. At the same time, the button structure can realize a seesaw-type movement and elastically cooperate with the tab of the automatic cleaning device, which realizes high convenience in attachment and detachment and prevents the stuck phenomenon.

[0107] Finally, it should be noted that the embodiments in this specification are gradually described by focusing on the differences between each embodiment and other embodiments, and that for the same and similar parts of each embodiment, it is sufficient to refer to each embodiment with respect to each other. Furthermore, since the system or device disclosed in the embodiment corresponds to the method disclosed in the embodiment, the description is relatively simple, and it is sufficient to refer to the description in the method section.

The present disclosure has been described in detail with reference to the above examples. However, it should be understood that a person skilled in the art may modify the technical solutions described in the above examples or substitute some technical features with equivalents, and such modifications or substitutions will not cause the essence of the relevant technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
