[0063] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., indicating orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0064] It should also be noted that, for ease of description, the accompanying drawings only show the parts relevant to the present invention, not the entire structure. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0065] Please see Figures 1 to 43As shown, the present invention provides a self-moving cleaning device, comprising: a body 100, having a first suction port F and a mounting cavity Z on its bottom; a drive wheel assembly located at the bottom of the body 100 for driving the body 100 forward or backward; omnidirectional wheels rotatably located at the bottom of the body 100 for assisting the body 100 in moving forward or backward; a first cleaning component 200 rotatably located within the first suction port F for cleaning the surface to be cleaned; a second cleaning component 300 rotatably located on the bottom of the body 100 for wet mopping the surface to be cleaned, the second cleaning component 300 being positioned behind the first cleaning component 200 in the forward direction of the body 100; and a dust collection box 400 located within the body 100, the dust collection box 400 having a dust collection chamber communicating with the first suction port F, for collecting dirt cleaned by the first cleaning component 200 under the action of a first suction force. In this configuration, the dust collection box 400 is positioned behind the first cleaning component 200 in the forward direction of the body 100, the drive wheel assembly is positioned behind the second cleaning component 300 in the forward direction of the body 100, and the omnidirectional wheel is positioned in front of the first cleaning component 200 in the forward direction of the body 100. The first cleaning component 200 and the second cleaning component 300 are shaped like cleaning rollers. The outer circumferential surfaces of the first cleaning component 200 and the second cleaning component 300 are cleaning surfaces used to clean the surface to be cleaned. The cleaning surface of the first cleaning component 200 contacts the surface to be cleaned to achieve the purpose of dust removal, and the cleaning surface of the second cleaning component 300 contacts the surface to be cleaned to achieve the purpose of wet mopping.

[0066] The aforementioned self-moving cleaning device is a robot capable of performing required cleaning operations in an environment without human guidance. In this invention, the aforementioned self-moving cleaning device is a floor scrubbing robot that simultaneously possesses sweeping and mopping functions, or a floor scrubbing robot with only mopping function. Having only mopping function means that only a rotating mop is provided at the bottom of the machine body, and the floor is cleaned through the rotation of the mop. The aforementioned floor scrubbing robot is hereinafter referred to as a floor scrubbing machine. The first cleaning component 200 is used to sweep the surface to be cleaned. During rotation, the first cleaning component 200 can loosen dirt adhering to the surface to be cleaned and cause dust on the surface to be cleaned to be stirred up, facilitating dust collection. When the floor scrubbing machine is working, a first suction force is generated within its body 100. Under the action of the first suction force, dirt on the surface to be cleaned enters the dust collection chamber of the dust collection box 400 through the first dust suction port F. Please refer to... Figures 28 to 35As shown, the dust collection chamber includes a dust inlet 410 for dust to enter and an air outlet 420 for clean air to exit. The dust inlet 410 is located above the first cleaning component 200. A dust air passage V is provided between the first cleaning component 200 and the dust inlet 410 for dust air circulation. The dust air passage V connects the first cleaning component 200 and the dust inlet 410 of the dust collection chamber. The dust air passage V is arc-shaped, inclined straight, or any shape that facilitates dust air flow. A filter unit 430 is detachably installed on the top of the dust collection chamber. The clean air generated after the dust air drawn into the dust collection chamber is filtered by the filter unit 430 is discharged from the dust collection box 400 through the air outlet 420, and the dust is collected in the dust collection box 400. Considering that the dust collection box 400 on the floor scrubber needs to be cleaned in time after it is full of garbage, if it is not cleaned in time, it will affect the cleaning effect of the floor scrubber. Therefore, the bottom of the dust collection chamber is equipped with an air guide unit H, which is used to connect with external equipment for dust removal.

[0067] In this invention, the machine body 100 is equipped with a dust box assembly, which includes the aforementioned dust collection box 400, the aforementioned dust and air passage V, and an air guide unit H. A first cleaning component 200 is located at the bottom front of the dust box assembly, and a second cleaning component 300 is located at the bottom of the dust box assembly. The air guide unit H includes an air inlet 460 that allows the suction airflow generated by the external device to enter the dust collection chamber, and a dust outlet 470 that allows dirt in the dust collection chamber to be discharged from the dust collection box 400. Both the air inlet 460 and the dust outlet 470 are connected to the dust collection chamber of the dust collection box 400. After the floor scrubber is used with the external device, the dust outlet 470 and the air inlet 460 are adapted to communicate with the first recycling bin of the external device. Please refer to [link to relevant documentation]. Figure 35 As shown, the air inlet 460 and dust outlet 470 are located behind the second cleaning component 300 in the forward direction of the machine body 100. Both the air inlet 460 and dust outlet 470 are located on the bottom of the dust collection box 400. The bottom of the machine body 100 has an air inlet interface 1123 corresponding to the air inlet 460 and a dust outlet interface 1124 corresponding to the dust outlet 470. When the dust outlet interface 1124 and air inlet interface 1123 of the floor scrubber are used in conjunction with external equipment, the dust collection chamber is forced to connect with the first recycling bin. When the floor scrubber is used in conjunction with external equipment, the second suction force generated on the external equipment creates a suction airflow within the dust collection box 400, which is used to transfer dirt from the dust collection chamber to the first recycling bin. Therefore, the automatic dust removal operation of the dust collection box 400 can be achieved through the air guide unit H of the dust collection box 400, avoiding manual emptying by the user and offering the advantage of ease of use.

[0068] To prevent dirt in the dust collection chamber from scattering into the external environment through the air inlet 460 and dust outlet 470 during suction, a first valve unit is provided at the air inlet 460, and a second valve unit is provided at the dust outlet 470. The first valve unit has a closed state (closing the air inlet 460) and an open state (opening the air inlet 460); the second valve unit has a closed state (closing the dust outlet 470) and an open state (opening the dust outlet 470). When the dust collection box 400 is connected to an external device, the first and second valve units respond to the suction airflow, switching the air inlet 460 and dust outlet 470 from the closed state to the open state, enabling the dust collection box 400 to connect to the external device and achieve automatic dust removal. During the above process, the second suction force drives both the first and second valve units to open, connecting the dust collection chamber to the first recycling bin.

[0069] Specifically, the first valve unit includes a first baffle 461, which is located inside the dust collection chamber. The first baffle 461 is made of an elastic material, preferably rubber. The top edge of the first baffle 461 is fixed to the wall of the dust collection chamber, while the other edges of the first baffle 461 are free edges, meaning they are not connected to the dust collection chamber. Therefore, when the first baffle 461 is subjected to a second suction force, it can open towards the interior of the dust collection chamber. The dirt inside the dust collection chamber tends to move inward under the action of the first baffle 461, preventing dirt from falling into the external environment through the air inlet 460 when the first baffle 461 is open. The second valve unit includes a second baffle 471, which is pivotally connected to the dust outlet 470, with the pivot shaft located at the top of the second baffle 471. The second baffle 471 is located outside the dust collection chamber. The second baffle 471 opens towards the outside of the dust collection chamber under the action of the second suction force. The purpose of this setting is to prevent the second baffle 471 from pushing the dirt out of the dust collection chamber when it opens, and also to prevent the dirt in the dust collection chamber from falling into the external environment.

[0070] To prevent the second baffle 471 from deviating from the dust outlet 470 under external force when the machine body 100 collides with an obstacle, an adsorption structure is also provided at the dust outlet 470. The function of the adsorption structure is to prevent dirt leakage caused by the second baffle 471 deviating from the dust outlet 470 under external force when the machine body 100 is not in conjunction with external equipment. In one embodiment, the adsorption structure includes a first magnetic element 472 and a second magnetic element 473, with opposite magnetic forces. The second magnetic element 473 is located at the bottom of the second baffle 471, and the first magnetic element 472 is located at the bottom of the dust collection chamber. Under the magnetic action of the first magnetic element 472 and the second magnetic element 473, the second baffle 471 is tightly pressed against the dust outlet 470, effectively preventing dirt leakage from the dust collection chamber during the cleaning process. Understandably, the magnetic attraction force generated by the first magnetic component 472 and the second magnetic component 473 is less than the second suction force. Therefore, during dust removal operations, the second baffle 471 can open smoothly under the action of the second suction force. Of course, the adsorption structure is not limited to the structure described above, and can also be other structures with adsorption functions, which will not be elaborated here.

[0071] Furthermore, the filter unit 430 includes a filter element 431 and a rigid perforated element 432, which are fixedly mounted to form a single unit. The rigid perforated element 432 is located on the side of the filter unit 430 closest to the interior of the dust collection chamber, and serves to prevent sharp particles in the dust and air within the dust collection chamber from damaging the filter element 431. The filter element 431 is HEPA, and the rigid perforated element 432 is wire mesh. It is understood that the filter element 431 and the rigid perforated element 432 may be, but are not limited to, the forms described above, and may also be other objects with the same function.

[0072] To facilitate the replacement of the filter unit 430, a top cover 440 is pivotally connected to the top of the dust collection box 400. The top cover 440 has an open state and a closed state. When the top cover 440 is in the open state, the filter element 431 is exposed on the top of the dust collection box 400. When the top cover 440 is in the closed state, the filter element 431 is sealed inside the dust collection box 400. A limiting block 441 is provided on the surface of the top cover 440 near the filter element 431. When the top cover 440 is in the closed state, the limiting block 441 abuts against the top of the filter element 431. The limiting block 441 has the function of limiting the installation of the filter element 431, preventing the filter unit 430 from becoming loose when the floor scrubber encounters vibration. Therefore, the filter unit 430 has the advantages of stable and reliable connection and good installation effect.

[0073] In this invention, a cleaning component assembly is provided on the machine body 100. The cleaning component assembly includes the aforementioned second cleaning component 300 and a side-drawing end cap unit 310 rotatably disposed at one end of the second cleaning component 300. The second cleaning component 300 is detachably connected to the machine body 100 through the side-drawing end cap unit 310. The other end of the second cleaning component 300 is drively connected to a driver 900 disposed within the machine body 100 and is driven to rotate by the driver 900. The second cleaning component 300 has a rotation axis and is detachably disposed within the mounting cavity Z along the direction of its rotation axis. The rotation axis of the second cleaning component 300 is perpendicular to the forward direction of the floor scrubber. The mounting cavity Z is disposed on the outer wall surface of the bottom of the machine body 100. The mounting cavity Z is a mounting groove with an open bottom and side wall. The second cleaning component 300 is detachably disposed within the mounting cavity Z through the side wall opening 1125, which is located on the side wall of the machine body 100.

[0074] Further, please refer to Figure 4 , Figures 13 to 18 As shown, the side-drawing end cap unit 310 includes a side-drawing end cap 311, which is rotatably mounted on one end of the second cleaning component 300 via a bearing 312 and a rotating shaft 313. The second cleaning component 300 is detachably connected to the machine body 100 via the side-drawing end cap 311. The second cleaning component 300 includes a hollow cylindrical second cleaning component body 3001, a driven end cap 3002 and an active end cap 3003 located at opposite ends of the second cleaning component body 3001. The side-drawing end cap 311 is rotatably mounted on the driven end cap 3002, and the active end cap 3003 is drively connected to the driver 900. A bearing 312 is fixedly installed inside the driven end cover 3002. A rotating shaft 313 passes through the driven end cover 3002 along the rotation axis of the second cleaning component 300. One end of the rotating shaft 313 is located outside the driven end cover 3002 and is fixedly connected to the side-pull end cover 311. The other end of the rotating shaft 313 is located inside the driven end cover 3002 and connected to the bearing 312. The driver 900 is connected to an output end 910. The active end cover 3003 of the second cleaning component 300 abuts against the output end 910. After the second cleaning component 300 is installed in the mounting cavity Z of the body 100, the side-pull end cover 311 and the output end 910 form an end support for the second cleaning component 300. Therefore, it has the advantages of convenient installation and stable and reliable support.

[0075] Furthermore, the side drawer end cap 311 mates with the side wall opening 1125, and the side wall opening 1125 is provided with at least one first connecting portion 1126. The side drawer end cap 311 is provided with at least one second connecting portion 3111 that mates with the first connecting portion 1126. The side drawer end cap 310 is connected to the body 100 through the mating of the first connecting portion 1126 and the second connecting portion 3111. The connection method between the first connecting portion 1126 and the second connecting portion 3111 includes, but is not limited to, the following: In one method, the first connecting portion 1126 is a screw thread distributed along the circumferential direction of the second cleaning component 300, and the second connecting portion 3111 is a snap-fit ​​block distributed along the circumferential direction of the second cleaning component 300; In another method, the first connecting portion 1126 is a first thread provided at the side wall opening 1125, and the second connecting portion 3111 is a second thread provided on the outer circumferential surface of the side drawer end cap 310, wherein the first thread and the second thread mate with each other.

[0076] To prevent the side drawer end cap 311 from coming loose during the operation of the floor scrubber, a circumferential limiting structure is provided between the side drawer end cap 311 and the machine body 100. The circumferential limiting structure includes a groove 3112 and a protrusion 1127 distributed along the rotation axis of the second cleaning component 300, and the groove 3112 and the protrusion 1127 engage with each other; wherein, the groove 3112 is provided on one of the second connecting part 3111 and the machine body 100, and the protrusion 1127 is provided on the other.

When the floor scrubber is used in conjunction with an external device, the first liquid inlet 510 is adapted to communicate with the replenishment chamber of the external device's replenishment tank; the first liquid outlet 520 is adapted to communicate with the mounting cavity Z. Thus, the cleaning solution in the first housing 500 is delivered to the mounting cavity Z through the first liquid outlet 520 to wet the second cleaning component 300, facilitating the wet mopping of the surface to be cleaned by the second cleaning component 300. When the floor scrubber is used in conjunction with an external device, the second liquid outlet 620 is adapted to communicate with the recovery chamber of the external device's second recovery tank, and the second liquid inlet 610 is adapted to communicate with the mounting cavity Z.

When the floor scrubber is connected to an external device through the replenishment interface 1122, the first liquid inlet 510 is forced to communicate with the replenishment chamber of the replenishment tank of the external device; when the floor scrubber is connected to an external device through the drain interface 1121, the second liquid outlet 610 is forced to communicate with the recovery chamber of the second recovery tank of the external device.

[0079] To prevent leakage at the liquid inlet 1122 and drain 1121 when the main body 100 is separated from external equipment, a liquid inlet 1122 is equipped with a liquid inlet interception mechanism 160. The liquid inlet interception mechanism 160 has a cut-off state and an open state; in the open state, the liquid inlet 1122 is connected to the first liquid inlet 510. Similarly, a drain 1121 is equipped with a drain interception mechanism 170, which has a cut-off state and an open state; in the open state, the drain 1121 is connected to the second liquid outlet 610.

The mounting cavity Z is provided with a second inlet and a second outlet, which are distributed on both sides of the first protrusion W. The first protrusion W extends along the rotation axis of the second cleaning component 300. The first liquid outlet 520 of the first housing 500 is sealed and connected to the second inlet, and the second liquid inlet 610 of the second housing 600 is sealed and connected to the second outlet. Driven by the rotation of the second cleaning component 300, the solution in the mounting cavity is carried from the second inlet, through the outer circumferential surface of the second cleaning component 300, to the second outlet.

[0081] Specifically, the inner wall of the mounting cavity Z is provided with a first arc surface R1 and a second arc surface R2 distributed on both sides of the first protrusion W. The first arc surface R1 and the second arc surface R2 can abut or be adjacent to the outer circumferential surface of the second cleaning component 300.

The second inlet is provided on the liquid inlet area J1, and the second outlet is provided on the liquid outlet area J2.

[0082] Furthermore, the mounting cavity Z is provided with a media distribution mechanism located in the liquid inlet area J1. The media distribution mechanism is used to wet the second cleaning component 300. Please refer to [link to relevant documentation]. Figures 19 to 24 As shown, the media distribution mechanism includes: a distribution seat 150, on which n-stage flow channels are provided, each stage of the flow channel having 2 n There are two outlets evenly distributed along the length of the distribution seat, forming 2 outlets. n-1 The components are symmetrically distributed on the distribution seat 150.

A main flow inlet 151 is provided in the middle of the primary flow channel, and the outlet of the final stage flow channel serves as the discharge outlet 152 of the medium. The distribution seat 150 is distributed along the rotation axis of the second cleaning component 300, that is, along the axial direction of the second cleaning component 300. The main flow inlet 151 is connected to the second inlet, or it can be regarded as the second inlet. The main flow inlet 151 is connected to the first housing 500, through which the cleaning solution is delivered to the medium distribution mechanism. In one embodiment, the first outlet 520 of the first housing 500 is sealed and connected to the second inlet of the mounting cavity Z via an outlet pipe 550. The outlet pipe 550 is provided with a second suction structure 551 for generating suction force, so as to drive the cleaning solution in the first housing 500 through the first outlet 520, the outlet pipe 550, and the main inlet 151 in sequence to be delivered into the mounting cavity Z. The second suction structure 551 is preferably a stop pump. It can be understood that the second suction structure 551 includes, but is not limited to, a stop pump, and may also be a water pump or other suction structures.

[0083] In this invention, the n-stage flow channel has 2n-1 There are 2 branch channels, and all branch channels at the same level form 2 n-2 The groups are symmetrically distributed on the distribution seat 150, where n≥2; in two adjacent flow stages, one outlet of the preceding flow stage branch channel serves as the inlet of one flow stage branch channel, and each branch channel has two symmetrically distributed outlets. The same outlet of the n+1 level branch channel corresponds to two n+2 level branch channels, which are symmetrically distributed on both sides of the same outlet of the nth level branch channel corresponding to the n+1 level branch channel.

[0084] Furthermore, the distribution seat 150 is hollow inside to form a hollow cavity, which extends along the length of the distribution seat 150; the n-stage flow channels are disposed within the hollow cavity. The distribution seat 150 includes a base 1501; the base 1501 has an inwardly recessed hollow cavity, and the bottom of the hollow cavity has a mounting groove corresponding one-to-one with the arrangement of the n-stage flow channels; and a cover plate 1502 is sealed on the opening of the mounting groove, the inner cavity of the mounting groove and the cover plate 1502 forming the aforementioned n-stage flow channels. In one embodiment, n is 3, please refer to [reference needed]. Figure 23 As shown, the distribution seat 150 is provided with a primary flow channel, a secondary flow channel, and a tertiary flow channel. The main inlet 151 is located on the wall of the mounting groove, and the outlet of the final flow channel is located through a portion of the base 1501 at the bottom of the mounting groove. The inner wall of the cover plate 1502 facing the mounting groove has a first protrusion S1 corresponding to the groove opening of the mounting groove; the first protrusion S1 is sealed and inserted into the groove opening of the mounting groove. The two opposite side walls of the mounting groove form a first slot and a second slot respectively with the inner wall of their respective hollow cavities; the inner wall of the cover plate 1502 also has a second protrusion S2 and a third protrusion S3 located on both sides of the first protrusion S1, and the second protrusion S2 and the third protrusion S3 are respectively inserted into the first slot and the second slot. The end of the base 1501 away from the first protrusion W is a blocking end 155 that bends into the mounting cavity Z, and the end face of the blocking end 155 can abut against the outer circumferential surface of the second cleaning component to prevent sewage solution from splashing out.

[0085] To ensure good flow uniformity at the outlet 152, at least one flow equalizing strip 1521 is provided within each outlet 152 in this invention to evenly divide the outlet. The number of flow equalizing strips 1521 should not be excessive, as too many strips will affect the liquid outflow rate of the outlet 152. Preferably, one or two flow equalizing strips 1521 are provided. To further improve the flow uniformity at the outlet 152, the surface of the base 1501, where the outlet end of the outlet 152 is located, has a recessed flow equalizing cavity 154 that corresponds to and communicates with each outlet 152. The flow equalizing cavity 154 is symmetrically conical, and the outlets 152 are distributed along the axis of symmetry of the cone.

[0086] In this invention, a media recovery mechanism 140 located in the liquid outlet zone J2 is also provided within the mounting cavity Z. The media recovery mechanism 140 is disposed adjacent to the second cleaning component 300 and is used for recovering the wastewater solution on the second cleaning component 300. Please refer to [link to relevant documentation]. Figures 25 to 27 As shown, the media recovery mechanism 140 includes: a scraper seat 141 disposed in the mounting cavity Z, the scraper seat 141 having a scraper blade 1412, a receiving cavity 1411, and a drain port 1413 communicating with the receiving cavity 1411; the receiving cavity 1411 and the scraper blade 1412 extend along the axial direction (rotation direction) of the second cleaning member 300; the scraper blade 142 abuts against the cleaning surface of the second cleaning member 300; the receiving cavity 1411 is configured to collect the wastewater solution obtained by squeezing the cleaning surface through the scraper blade 142; and a filter element 142 having a plurality of mesh openings, the filter element 142 being disposed in the receiving cavity 1411 and distributed between the cleaning surface of the second cleaning member 300 and the drain port 1413. The scraper blade 1412 forms a scraping structure near the first protrusion W in the liquid outlet area J2; the scraper blade 1412 extends toward the mounting cavity Z and can be squeezed onto the outer circumferential surface of the second cleaning member 300. The drain port 1413 is connected to the second outlet mentioned above, and can also be regarded as the second outlet. The filter element 142 is closer to the second cleaning element 300 than the second outlet. The filter element 142 is configured to create a negative pressure in the receiving cavity 1411 by adsorbing the sewage solution, so that the sewage solution flows towards the drain port 1413.

[0087] Specifically, the bottom of the scraper seat 141 is provided with a friction surface 1414 that contacts the cleaning surface of the second cleaning member 300; the friction surface 1414 is recessed in the direction away from the cleaning surface to form a receiving cavity 1411, and the scraper blade 1412 protrudes on the edge of the cavity opening of the receiving cavity 1411 in the direction towards the cleaning surface, and the scraper blade 1412 and the receiving cavity 1411 are of equal length.

[0088] To enable the filter element 142 to perform adsorption, it is made of an adsorbent material with liquid adsorption capabilities, such as sponge, silica gel, or nylon. The filter element 142 has several mesh openings arranged in an array, and can be considered a partition-type structure. To reduce wear on the filter element 142, a preset gap exists between the filter element 142 and the cleaning surface of the second cleaning element 300. This reduces friction between the second cleaning element 300 and the filter element 142 during rotation, extending the service life of the filter element 142. A connecting fitting part G is provided within the receiving cavity 1411, and the filter element 142 is disposed on the connecting fitting part G. The connecting fitting part G is configured to form a stepped structure on the cavity wall of the receiving cavity 1411 for mounting and positioning the filter element 142. This provides the advantage of convenient installation.

[0089] Considering that dirt and grime may adhere to the scraper seat 141 during operation, requiring frequent disassembly and cleaning, the scraper seat 141 is detachably mounted within the mounting cavity Z. For details, please refer to... Figure 26 As shown, the scraper seat 141 is provided with a mounting structure 143. The scraper seat 141 is detachably mounted on the target part via the mounting structure 143, and the target part is the mounting cavity Z. The mounting structure 143 includes a magnetic element 1431 disposed on the top of the scraper seat 141. The scraper seat 141 is also provided with a mounting groove 1432 for accommodating the magnetic element 1431. The magnetic element 1431 is configured to allow the scraper seat 141 to be attracted to the target part by magnetic force. It can be understood that the mounting cavity Z can be made of a material capable of attracting magnetic objects, or a magnetic pole with the opposite magnetic properties to the magnetic element 1431 can be provided in the mounting cavity Z, and the scraper seat 141 can be installed by the attraction force between the magnetic pole and the magnetic element 1431.

[0090] In this invention, the aforementioned media recovery mechanism 140 is connected to a second housing 600, which stores the wastewater solution collected via the media recovery mechanism 140. The second inlet 610 of the second housing 600 is connected to the outlet 1413 via a wastewater inlet pipe (not shown). Please refer to [link to relevant documentation]. Figure 9 and Figure 38 As shown, the second housing 600 is also equipped with a negative pressure generator, which is used to create a negative pressure inside the second housing 600. This negative pressure refers to the aforementioned third suction force. Under the action of the third suction force, the wastewater solution on the second cleaning component 300 is sucked into the second housing 600 through the media recovery mechanism 140. The structure of the aforementioned negative pressure generator is as follows: it includes a vacuum port 650 on the second housing 600, a flexible hose 652 connected to the vacuum port 650, and a vacuum pump 651 mounted on the flexible hose 652. The filter element 142 assists in creating a negative pressure within the receiving cavity 1411, causing the wastewater solution to flow towards the drain port 1413.

[0091] The present invention also provides a mating structure, which includes the aforementioned dust collection box 400, the aforementioned first box body 500, and the aforementioned second box body 600. Any one of the dust collection box 400, the first box body 500, and the second box body 600 is detachably disposed within the body 100, and the first box body 500 and the second box body 600 are distributed on the opposite side walls of the dust collection box 400. Preferably, the dust collection box 400, the first box body 500, and the second box body 600 are all suitable for being detachably disposed within the body 100. The mating structure further includes a mounting base 130 housed within the body 100, on which the first box body 500, the dust collection box 400, and the second box body 600 are detachably disposed. The mounting base 130 is detachably disposed within the body 100. The mounting base 130 has a first groove, a second groove, and a third groove that are sequentially distributed and spaced apart. The first housing 500, the dust collection box 400, and the second housing 600 are detachably disposed within the first groove, the second groove, and the third groove, respectively. The first groove, the second groove, and the third groove are located on the top of the mounting base 130, and the first housing 500, the dust collection box 400, and the second housing 600 are detachably installed vertically within their respective grooves. The bottom of the mounting base 130 also has an upwardly recessed area X; the mounting cavity Z corresponds to the recessed area X for mounting the second cleaning component 300.

[0092] In this invention, the body 100 is provided with a cleaning component, which includes the dust box assembly, the first cleaning component 200, the second cleaning component 300, the mounting base 130, the first box body 500, and the second box body 600. The first box body 500 and the second box body 600 are arranged symmetrically on both sides of the dust collection box 400. The dust box assembly is located inside the mounting base 130. The bottom of the mounting base 130 is provided with a clearance area K so that the air inlet 460 is connected to the air inlet interface 1123 and the dust outlet 470 is connected to the dust outlet interface 1124.

[0093] To identify whether the first housing 500, dust collection box 400, and second housing 600 are installed on the mounting base 130, the mounting base 130 is provided with a first assembly detection component 131, and the dust collection box 400, the first housing 500, and the second housing 600 are respectively provided with second assembly detection components 132 that cooperate with the first assembly detection component 131. The first assembly detection component 131 can be a Hall sensor, and the second assembly detection component 132 can be a magnet; the first assembly detection component 131 and the second assembly detection component 132 are configured in a one-to-one correspondence. Thus, the induction between the Hall sensor and the magnet can determine whether the first housing 500, dust collection box 400, and second housing 600 are properly installed. It is understood that the first assembly detection component 131 and the second assembly detection component 132 include, but are not limited to, the above-described structures, and can also be other mutually inductive components.

[0094] To facilitate user removal of the dust collection box 400 from the mounting base 130, a handle 450 is pivotally connected to the top of the dust collection box 400, and a protrusion 451 is provided at the pivot point between the handle 450 and the dust collection box 400. The handle 450 has an initial state and a pulled state; when the handle 450 is in the initial state, it is approximately parallel to the upper surface of the dust collection box, and when the handle 450 is in the pulled state, it is approximately perpendicular to the upper surface of the dust collection box. In this invention, the protrusion 451 is configured to fix or release the dust collection box 400 in response to the change in the handle 450 between the initial and pulled states, thereby achieving a detachable connection between the dust collection box 400 and the mounting base 130. Please refer to... Figures 31 to 35 As shown, the mounting base 130 is provided with a slot 1301 that mates with the protrusion 451; when the handle 450 is in the initial state, the protrusion 451 is engaged with the slot 1301; when the handle 450 is in the lifting state, the protrusion 451 disengages from the slot 1301. The edge of the handle 450 is also provided with spaced-apart blocks 452, and the top of the dust collection box 400 is provided with a groove 480 that mates with the blocks 452. The groove 480 is located at the pivot point where the dust collection box 400 and the upper cover 440 are pivotally connected. When the handle 450 is in the horizontal state, the blocks 452 are engaged in the groove 480; when the user pulls the handle 450, the blocks 452 disengage from the groove 480.

[0095] To monitor the liquid level within the first container 500 in real time, a liquid level detection structure is provided within the first liquid storage chamber of the first container 500. In this invention, the first liquid storage chamber has a height difference in the vertical direction. Please refer to [link / reference needed]. Figure 36 and Figure 37As shown, the liquid level detection structure includes a first conductive element 530 located at the lowest position of the first liquid storage chamber for detecting the lowest liquid level and a second conductive element 540 located at the highest position of the first liquid storage chamber for detecting the highest liquid level. A first terminal 133 for engaging with the first conductive element 530 and a second terminal 134 for engaging with the second conductive element 540 are provided in the first groove of the mounting base 130. The cleaning solution is a conductive medium. When the first housing 500 is installed into the first groove of the mounting base 130, the first conductive element 530 abuts against the first terminal 133, and the second conductive element 540 abuts against the second terminal 134. In this invention, the first conductive element 530 and the second conductive element 540 are metal sheets with positive and negative electrodes, exposed at the bottom of the first housing. The first terminal 133 and the second terminal 134 are floating pins located within the first groove of the mounting base 130. The floating refers to the first terminal 133 and the second terminal 134 being spring-loaded onto the mounting base 130. After the first housing 500 is installed onto the mounting base 130, the first terminal 133 and the second terminal 134 abut against the first conductive element and the second conductive element, respectively. Taking the detection of the lowest point as an example, when there is cleaning solution at the lowest point of the first liquid storage chamber, the positive and negative terminals of the first conductive element 530 are connected, thereby forming an electrical connection; when there is no cleaning solution at the lowest point of the first liquid storage chamber, the positive and negative terminals of the first conductive element 530 cannot be connected, and even if the first conductive element 530 abuts against the first terminal 133, no electrical connection will be formed.

[0096] Similarly, to monitor the liquid level within the second container 600, a full-load detection structure 640 is installed in the second liquid storage chamber of the second container 600 to detect the highest liquid level within the second container 600. The difference between the second container 600 and the first container 500 is that only the highest liquid level needs to be detected in the second container 600; the lowest liquid level is not required. Please refer to [link / reference]. Figure 39 As shown, the full-load detection structure 640 includes a float 641, a float rod 642, and a permanent magnet (not shown). The float 641 is located at one end of the float rod 642. The end of the float rod 642 away from the float 641 is rotatably located in the second housing 600 via a swing shaft 643. The permanent magnet is fixed on the float 641. A Hall sensor 644 that cooperates with the permanent magnet is provided in the second housing 600. The density of the float 641 is less than the density of the sewage solution in the second housing.

[0097] Furthermore, the mounting base 130 is provided with a first inlet connector 135 for connection with the first liquid inlet 510 and a first outlet connector 136 for connection with the first liquid outlet 520, wherein the first inlet connector 135 and the first outlet connector 136 are located at the bottom of the first groove. The mounting base 130 is provided with a second inlet connector 137 for connection with the second liquid inlet 610 and a second outlet connector 138 for connection with the second liquid outlet 620, wherein the second inlet connector 137 and the second outlet connector 138 are located at the bottom of the third groove. The first inlet connector 135 is connected to a replenishment pipe 1601 and is connected to a replenishment interception mechanism 160 through the replenishment pipe 1601; the second outlet connector 138 is connected to a drain pipe 1701 and is connected to a drain interception mechanism 170 through the drain pipe 1701. The purpose of providing the first liquid inlet connector 135, the first liquid outlet connector 136, the second liquid inlet connector 137, and the second liquid outlet connector 138 is to enable a detachable connection between the first housing 500 and the mounting base 130, and between the second housing 600 and the mounting base 130. Without these connectors, the first liquid inlet 510, the first liquid outlet 520, the second liquid inlet 610, and the second liquid outlet 620 would be directly connected to the pipeline, making it inconvenient to remove the first housing 500 and the second housing 600 from the mounting base 130.

[0098] Considering the leakage problem after the first housing 500 is removed from the mounting base 130, in this invention, the first liquid inlet 510 and / or the first liquid outlet 520 are provided with a first intercepting mechanism. The first intercepting mechanism has a cut-off state of cutting off the first liquid inlet 510 and / or the first liquid outlet 520 and an open state of opening the first liquid inlet 510 and / or the first liquid outlet 520. When the first housing 500 is separated from the mounting base 130, the first intercepting mechanism is in the cut-off state. Specifically, the location of the first intercepting mechanism can be divided into three cases: First, the first intercepting mechanism is provided on the first liquid inlet 510, and the first intercepting mechanism has a cut-off state of cutting off the first liquid inlet 510 and an open state of opening the first liquid inlet 510; Second, the first intercepting mechanism is provided on the first liquid outlet 520, and the first intercepting mechanism has a cut-off state of cutting off the first liquid outlet 520 and an open state of opening the first liquid outlet 520; Third, the first intercepting mechanism is provided on both the first liquid inlet 510 and the first liquid outlet 520, and the first intercepting mechanism has a cut-off state of cutting off the first liquid inlet 510 and the first liquid outlet 520 and an open state of opening the first liquid inlet 510 and the first liquid outlet 520. Additionally, the leakage problem at the first liquid inlet 510 can also be solved by providing a hollow extension column 511 at the first liquid inlet 510. Please refer to [link to relevant documentation]. Figure 37As shown, the hollow extension column 511 is housed within the first liquid storage cavity. The hollow extension column 511 is a thin tubular component with openings at the top and bottom, and its top opening is positioned close to the top of the first liquid storage cavity. Therefore, after the first housing 500 is removed, the liquid in the first liquid storage cavity cannot leak out from the first liquid inlet 510.

[0099] Similarly, considering the leakage problem after the second housing 600 is removed from the mounting base 130, in this invention, the second liquid inlet 610 and / or the second liquid outlet 620 are provided with a second intercepting mechanism 630. The second intercepting mechanism 630 has a cut-off state that cuts off the second liquid inlet 610 and / or the second liquid outlet 620 and an open state that opens the second liquid inlet 610 and / or the second liquid outlet 620. When the second housing 600 is separated from the mounting base 130, the second intercepting mechanism 630 is in the cut-off state. Specifically, the second intercepting mechanism 630 can be positioned in three ways: First, the second intercepting mechanism 630 is provided on the second inlet 610, and the second intercepting mechanism 630 has a cut-off state of cutting off the second inlet 610 and an open state of opening the second inlet 610; Second, the second intercepting mechanism 630 is provided on the second outlet 620, and the second intercepting mechanism 630 has a cut-off state of cutting off the second outlet 620 and an open state of opening the second outlet 620; Third, the second intercepting mechanism 630 is provided on both the second inlet 610 and the second outlet 620, and the second intercepting mechanism 630 has a cut-off state of cutting off the second inlet 610 and the second outlet 620 and an open state of opening the second inlet 610 and the second outlet 620.

[0100] In this invention, the first intercepting mechanism, the second intercepting mechanism 630, the liquid replenishment intercepting mechanism 160, and the sewage discharge intercepting mechanism 170 have the same structure. For ease of explanation, the liquid replenishment intercepting mechanism 160 will be used as an example for illustration. Please refer to [link to relevant documentation]. Figure 43 As shown, the liquid replenishment and interception mechanism 160 includes:

[0101] The valve body 161 has a fluid passage and an outlet 1611 and an inlet 1612 communicating with the fluid passage; the fluid passage has a first sealing surface 1613 distributed around its inner wall; a sealing seat 162 is slidably disposed in the fluid passage; the sealing seat 162 has a second sealing surface 1614 facing the first sealing surface 1613; a sealing body 163 is fixed on the first sealing surface 1613 or the second sealing surface 1614; a biasing member 164 is disposed between the valve body 161 and the sealing seat 162, applying a biasing force toward the first sealing surface 1613 to the sealing seat 162, so that the sealing seat 162 abuts against the inlet 1612, thereby putting the liquid replenishment and shut-off mechanism 160 in a shut-off state. In the cut-off state, under the aforementioned bias pressure, the sealing body 163 is clamped between the first sealing surface 1613 and the second sealing surface 1614, sealing both surfaces. In this state, the solution cannot flow within the fluid channel. In the open state, the sealing seat 162 is forced apart from the first sealing surface 1613 by the abutting force of the external ejector. In this state, the solution within the fluid channel can flow from the inlet 1612 to the outlet 1611.

[0102] Specifically, the sealing seat 162 includes a valve core 1621 movably disposed within the fluid channel. The valve core 1621 has the aforementioned second sealing surface 1614. The surface of the valve core 1621 with the second sealing surface 1614 is defined as the first end face, and the surface opposite to the first end face is defined as the second end face. The first end face also has a first rod portion 1622 extending through an inlet 1612 to the outside of the valve body 161. The first rod portion 1622 is used to cooperate with an external ejector. The second end face has a second rod portion 1623 extending in a direction away from the first end face. The second rod portion 1623 is located within the fluid channel and serves to guide the movement of the valve core 1621. The fluid channel also has guide grooves 1615 distributed along the extending direction of the second rod portion 1623. The second rod portion 1623 is inserted into the guide grooves 1615 to guide the movement of the valve core 1621. The first rod portion 1622 and the second rod portion 1623 are parallel or coaxially distributed. The biasing element 164 is preferably a spring, and is distributed along the extending direction of the first rod portion 1622 and the second rod portion 1623, so that the direction of the elastic force provided by the biasing element 164 is consistent with the moving direction of the valve core 1621. The sealing body 163 is an annular sealing ring. In one embodiment, the sealing body 163 is fixed on the valve core 1621 and moves with the valve core 1621. The surface of the sealing body 163 that mates with the first sealing surface 1613 is provided with protruding ridges to improve the sealing performance.

[0103] In this invention, whether external ejector Ts are required on the first liquid inlet connector 135, the first liquid outlet connector 136, the second liquid inlet connector 137, and the second liquid outlet connector 138 depends on whether flow-stopping mechanisms are provided on their corresponding first liquid inlet 510, first liquid outlet 520, second liquid inlet 610, and second liquid outlet 620. The liquid replenishment flow-stopping mechanism 160 on the liquid replenishment interface 1122 and the sewage discharge flow-stopping mechanism 170 on the sewage discharge interface 1121 are triggered by external devices.

[0104] The above description has fully illustrated the connection relationships between the first housing 500, the second housing 600, the second cleaning component 300, the mounting cavity Z, the media distribution mechanism, and the media recovery mechanism. Those skilled in the art will understand the following working process of the circulation system:

[0105] For ease of explanation, the following limitation is made: only the second outlet 620 is equipped with the second intercepting mechanism Y, while the second inlet 610, the first inlet 510, and the first outlet 520 are not equipped with intercepting mechanisms. The reasons are as follows: a filter 560 is connected to the first outlet 520, so when the first housing 500 is separated from the mounting base 130, the liquid in the first storage chamber is not easily leaked out through the first outlet 520; an extension column 511 structure can be used at the first inlet 510, so when the first housing 500 is separated from the mounting base 130, the first inlet 510 is also not easily leaked; similarly, the second inlet 610 can also adopt the same extension column 511 structure as the first inlet 510, so when the second housing 600 is separated from the mounting base 130, the second inlet 610 is also not easily leaked. The second intercepting mechanism Y of the second outlet 620 is triggered to be in the open state after the second housing 600 is installed on the mounting base 130. The second intercepting mechanism Y of the second outlet 620 only changes from the open state to the cut-off state when the second housing 600 is separated from the mounting base 130. The specific working process is as follows:

[0106] When the floor scrubber is not connected to external equipment, it is performing a cleaning task. The first outlet 520 delivers cleaning liquid to the media distribution mechanism in the mounting cavity Z through the outlet pipe 550. The media distribution mechanism wets the second cleaning component 300, which then wets and mops the surface to be cleaned. Simultaneously, under the third suction force generated by the vacuum pump 651, the second housing 600 draws the wastewater solution from the second cleaning component 300 into the second storage chamber through the media recovery mechanism and the wastewater inlet pipe in the mounting cavity Z. When the cleaning solution in the first housing 500 is exhausted or the wastewater solution stored in the second housing 600 is full, the floor scrubber connects to external equipment for replenishment or discharge.

[0107] After the external equipment is used in conjunction with the floor scrubber, the liquid replenishment and interception mechanism 160 on the liquid replenishment interface 1122 is in the open state under the action of the external equipment. The cleaning solution in the liquid replenishment tank of the external equipment is replenished into the first box 500 by passing through the liquid replenishment interface 1122, the inlet 1612 of the liquid replenishment and interception mechanism 160, the outlet 1611 of the liquid replenishment and interception mechanism 160, the liquid replenishment pipe 1601, the first liquid inlet connector 135, and the first liquid inlet 510. This is the liquid replenishment process.

[0108] After the external equipment is used in conjunction with the floor scrubber, the sewage interception mechanism 170 on the sewage discharge port 1121 is in the open state under the action of the external equipment. The sewage solution in the second box 600 passes through the inlet of the second interception mechanism Y, the outlet of the second interception mechanism Y, the second liquid outlet 620, the second liquid outlet connector 138, the sewage pipe 1701, the inlet of the sewage interception mechanism 170, the outlet of the sewage interception mechanism 170, and finally the sewage discharge port 1121, and is discharged into the second recycling box of the external equipment. This is the sewage discharge process.

[0109] In this invention, the fuselage 100 includes a fuselage body 110 and a strike plate assembly floating at the front of the fuselage body 110. (See also...) Figure 11 and Figure 12As shown, the impact plate assembly includes: an impact plate body 120, which is stepped and covers the front of the main body 110 of the floor scrubber; a second triggering mechanism connected to an external drive circuit, configured to trigger and send a stop signal to the floor scrubber when the impact plate body 120 is displaced due to a collision; a buffering mechanism configured to provide elastic buffering for the impact plate body 120 if it further displaces; and a recovery mechanism configured to elastically recover the displacement of the impact plate body 120 when it is displaced, restoring it to the central part of the front of the main body 110. Through these methods, the stepped impact plate body 120 can trigger collisions at the front and sides of the floor scrubber in the direction of operation, effectively improving the overall obstacle avoidance capability of the floor scrubber. When the impact plate body 120 collides with an obstacle, an impact force is generated between the impact plate body 120 and the obstacle. Under the action of the impact force, the floor scrubber will generate vibration and noise. The buffer mechanism can provide elastic cushioning for the impact plate body 120, effectively reducing vibration and noise, improving user comfort, and enhancing the vibration resistance of the floor scrubber. Considering that the impact plate body 120 will develop a form and position deviation with the machine body 110 after multiple collisions, the aforementioned form and position deviation refers to the difference in position and shape between the impact plate body 120 and the machine body 110 compared to the factory state. Such form and position deviation can cause the floor scrubber to collide without triggering, and also affects the aesthetic appearance. In this invention, the recovery mechanism can reduce or eliminate the aforementioned form and position deviation, thereby ensuring triggering sensitivity and aesthetic appearance.

[0110] In this invention, the fuselage body 110 includes a disc-shaped main body P and a forward protrusion Q protruding from the front of the main body P, forming a front-rounded shape. The top surface of the forward protrusion Q is lower than the top surface of the main body P, forming a stepped structure at the front of the fuselage body 110. The impact plate body 120 covers the stepped structure. The impact plate body 120 includes a first impact plate 121 covering the outer peripheral surface of the forward protrusion Q and a second impact plate 122 extending from the top of the first impact plate 121 toward the top surface of the main body P. The second impact plate 122 is arc-shaped and covers the main body P.

[0111] The first impact plate 121 and the second impact plate 122 are configured as follows: First, the first impact plate 121 and the second impact plate 122 are integrated; second, the first impact plate 121 and the second impact plate 122 are separate vertically. When the first impact plate 121 and the second impact plate 122 are separate vertically, installation gaps are unavoidable during installation. External dust and moisture can enter the floor scrubber through these gaps. To avoid this, a rubber seal (not shown) is installed at the connection between the first impact plate 121 and the second impact plate 122. This rubber seal effectively reduces or prevents external dust and moisture from entering the floor scrubber, thus extending the equipment's lifespan to some extent.

[0112] To enable omnidirectional obstacle detection in front of the machine body 110, the second triggering mechanism includes multiple trigger sensors 124. One end of each trigger sensor 124 abuts against the impact plate body 120. The multiple trigger sensors 124 are distributed on the front side and both sides of the stepped structure, which are the left and right sides of the floor scrubber's forward direction. Therefore, during the forward movement of the machine body 110, collision triggering can be achieved at its front end and both sides, enabling omnidirectional obstacle detection and timely adjustment of the floor scrubber's operating status.

[0113] Specifically, the multiple trigger sensors 124 distributed on the front surface of the stepped structure are arranged in two groups, upper and lower. The first group is located on the front surface of the main body P corresponding to the second impact plate 122, and the second group is located on the front surface of the protrusion Q corresponding to the first impact plate 121. Therefore, regardless of whether the collision zone between the impact plate body 120 and the obstacle is located at the top, bottom, or middle of the impact plate body 120, the trigger sensors 124 can be successfully triggered, exhibiting the advantage of high trigger sensitivity. The aforementioned multiple trigger sensors 124 are collision switches; however, it is understood that the aforementioned multiple trigger sensors 124 include, but are not limited to, collision switches, and can also be other collision triggering devices and structures.

[0114] Furthermore, the buffer mechanism includes multiple first elastic buffer elements 125 disposed on the forward protrusion Q for impact buffering of the first impact plate 121, and multiple second elastic buffer elements 126 disposed on the main body P for impact buffering of the second impact plate 122. The first elastic buffer elements 125 and the second elastic buffer elements 126 are made of elastic materials, such as rubber, nylon, or sponge. When the impact plate body 120 collides with an obstacle, the obstacle generates a reaction force on the impact plate body 120. This reaction force drives the impact plate body 120 towards the fuselage body 110, causing further displacement of the impact plate body 120. The first elastic buffer elements 125 and the second elastic buffer elements 126 can absorb part of the impact force generated during the collision, achieving elastic buffering. The multiple first elastic buffer elements 125 can be spaced apart or connected sequentially to form a continuous arrangement. Similarly, the multiple second elastic buffer elements 126 can be spaced apart or continuously arranged. In this invention, the first elastic buffer element 125 and the second elastic buffer element 126 are preferably detachably mounted on the main body 110, thereby enabling easy replacement.

[0115] Furthermore, the recovery mechanism includes at least one elastic element 123. The impact plate body 120 is floatingly disposed at the front of the fuselage body 110 via the elastic element 123. The elastic element 123 is disposed on the fuselage body 110 and connected to the impact plate body 120. The elastic element 123 is preferably a spring. One end of the elastic element 123 is engaged with the fuselage body 110, and the other end of the elastic element 123 is engaged with the impact plate body 120. In order to make the impact plate body 120 return to its original position and remain in the central position at the front of the fuselage body 110, the elastic elements 123 are disposed on the fuselage body 110 in an axially symmetrical manner, and the distance between the front ends of any pair of elastic elements 123 is less than the distance between the rear ends of any pair of elastic elements 123.

[0116] In this invention, the main body 110 includes a bottom cover 112 and a top cover 111. The bottom of the bottom cover 112 is provided with a first suction port F, a mounting cavity Z, a drive wheel assembly, universal wheels, a first cleaning component 200, and a second cleaning component 300. A decorative cover 113 is pivotally connected to the top of the top cover 111. The decorative cover 113 has a closed state that covers the dust collection box 400, the first box body 500, and the second box body 600, thus enclosing the dust collection box 400, the first box body 500, and the second box body 600 within the main body 110, and an open state that flips upwards around the pivot axis, exposing the dust collection box 400, the first box body 500, and the second box body 600 to the outside. This allows for easy removal of the dust collection box 400, the first box body 500, and the second box body 600, and also facilitates easy replacement of the HEPA filter on the dust collection box 400, providing the advantage of ease of use.

[0117] Understandably, the self-moving cleaning device of the present invention can be applied to different usage scenarios, as illustrated below.

[0118] The self-moving cleaning device of this invention can be applied to a cleaning system. This cleaning system includes a cleaning base station (not shown) and the self-moving cleaning device. The cleaning base station is used to house the self-moving cleaning device and perform dust removal, liquid replenishment, and wastewater discharge operations. The cleaning base station is equipped with a first recycling bin, a second recycling bin, and a liquid replenishment bin. When the interface between the cleaning base station and the body 100 of the self-moving cleaning device is engaged, the dust outlet 470 and air inlet 460 of the body 100 are respectively adapted to communicate with the first recycling bin of the cleaning base station for dust removal; the first liquid inlet 510 is connected to the liquid replenishment chamber of the liquid replenishment bin for liquid replenishment; and the second liquid outlet 620 is connected to the second recycling chamber of the second recycling bin for wastewater discharge.
