The terms "first" and "second" are used only for the purpose of description and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly specified.

[0032] In cleaning equipment with related technologies, the water distributor operates in a single mode, and the wetting effect of the roller brush is limited and the wetting process is relatively long, which cannot meet different work needs. For example, when there are heavy stains on the ground, it is desirable for the water distributor to quickly wet the roller brush so as to achieve a quick start and initial cleaning of the cleaning work.

[0033] The purpose of this disclosure is to provide a cleaning device that offers a solution suitable for different cleaning needs.

[0034] To illustrate the technical solutions described in this disclosure, the following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0035] This disclosure provides a cleaning device 100 for cleaning the ground.

[0036] Please refer to Figures 1 and 2. Specifically, the cleaning device 100 includes a housing 1, a roller brush 2, a first drive member 3, and a water distributor 4. The roller brush 2 is rotatably mounted on the housing 1 of the cleaning device 100. The first drive member 3 and the water distributor 4 are both mounted on the housing 1. The first drive member 3 is connected to the water distributor 4 and is used to drive the water distributor 4 to move so that at least the outlet 4101 of the water distributor 4 can switch between at least a first position close to the roller brush 2 (see Figure 4) and a second position away from the roller brush 2 (see Figure 5).

[0037] The cleaning device provided in this disclosure has the following advantages: The cleaning device includes a housing, a roller brush, a first drive member, and a water distributor. The roller brush is rotatably mounted on the housing of the cleaning device. The first drive member and the water distributor are both mounted on the housing. The first drive member is connected to the water distributor and is used to drive the water distributor to move, so that the water distributor can switch between at least a first position close to the roller brush and a second position far from the roller brush. In the first position, the water distributor is suitable for uniformly wetting the roller brush. In the second position, the water distributor is suitable for quickly wetting the roller brush and / or the ground. Thus, the cleaning device can be adapted to different cleaning needs.

[0038] As shown in Figures 1 and 2, the side of the water distributor 4 facing away from the roller brush 2 (see the inlet 4102 shown in Figure 3) is used to connect to a clean water tank (not shown) mounted on the housing 1 via a pipe 8. Water in the clean water tank flows to the roller brush 2 through the pipe 8 and the water distributor 4, wetting the roller brush 2. Multiple outlets 4101 are distributed on the side of the water distributor 4 facing the roller brush 2, as shown in Figure 6.

[0039] As shown in Figure 4, in the first position, the water distributor 4 is positioned close to the roller brush 2. In this position, the water from the water distributor 4 can be sprayed almost entirely, or even completely, onto the surface of the roller brush 2, thus improving the uniformity of spraying across the surface. This is suitable for routine floor cleaning, ensuring even cleaning and preventing uncleaned areas or residual water. As shown in Figure 5, in the second position, the water distributor 4 is positioned away from the roller brush 2. In this position, the water distributor 4 can quickly wet both the floor and the roller brush 2. This is suitable for scenarios requiring rapid or preliminary cleaning, where the floor is heavily soiled and the cleaning equipment 100 needs to quickly and initially remove the stains. Because the water distributor 4 is positioned away from the roller brush 2, some water can be sprayed directly onto the floor, quickly wetting it.

[0040] For some floor materials, such as smooth and poorly absorbent surfaces like tiles and wood, the water divider 4 can be positioned in the first position. In this case, the surface of the roller brush 2 is consistently wetted, which can prevent water residue from remaining on the floor after cleaning.

[0041] The cleaning device 100 in this embodiment can be a handheld cleaning device, such as a handheld mop or a handheld vacuum and mop combo, or a self-propelled cleaning device, such as a self-propelled mop or a self-propelled vacuum and mop combo.

[0042] In some embodiments, the first drive member 3 and the pipe 8 may be disposed inside the housing 1, and a portion of the roller brush 2 may be exposed outside the housing 1 to contact the ground.

[0043] In some embodiments, the cleaning device 100 may further include a clean water tank, a wastewater tank, a water spray assembly, a sludge suction assembly, etc. (not shown) disposed in the housing 1. The clean water tank is connected to the water distributor 4 via a pipe 8. The water spray assembly is disposed on the housing 1 and is used to provide power for clean water to flow from the clean water tank to the water distributor 4. The wastewater tank is connected to the sludge suction port 10. The sludge suction assembly is disposed on the housing 1 and is used to provide power for wastewater, garbage, etc. to enter the wastewater tank.

[0044] In some embodiments, taking a self-propelled cleaning device as an example, the cleaning device 100 further includes a walking component disposed at the bottom of the housing 1, and a second driving member (neither shown) disposed inside the housing 1, the second driving member being used to drive the walking component.

[0045] Referring to Figures 4 and 5, in one embodiment, the water distributor 4 is rotatably mounted on the housing 1, and the rotational axis of the water distributor 4 is parallel to the rotational axis of the roller brush 2. In Figures 4 and 5, the dashed curved arrows indicate the rotational direction of the water distributor 4, and the dotted-dashed curved arrows indicate the rotational direction of the roller brush 2. The first driving member 3 is used to drive the water distributor 4 to rotate, thereby enabling the water distributor 4 to move closer to and further away from the roller brush 2 in a rotating manner.

[0046] In one embodiment, the rotation center axis of the water distributor 4 is located at its upper end in the vertical direction; that is, the outlet 4101 of the water distributor 4 is lower than its rotation center axis. Referring to Figures 4 and 5, the angle of the water distributor 4 relative to the vertical direction differs in the first and second positions. From the first position to the second position, the outlet 4101 of the water distributor 4 is deflected downwards at a certain angle. Therefore, in the second position, the water flowing from the water distributor 4 flows downwards more easily, allowing some water to flow directly onto the ground.

[0047] It should be noted that the terms "above" and "below" used in the preceding and following text are based on the orientation of the cleaning equipment 100 in its working state. In its non-working state, the cleaning equipment 100 may be arranged in other orientations, but this does not affect the relative positional relationships between the components of the cleaning equipment 100.

[0048] Not limited to this, in other embodiments, where permitted, the rotation center axis of the water distributor 4 may also be set higher than or flush with the outlet 4101 of the water distributor 4.

[0049] Specifically, as shown in Figures 4 to 6, the first driving component 3 includes a motor 31, a drive shaft 32, and a connector 35 connected in sequence. The rotation center axes of the drive shaft 32 and the connector 35 are parallel to the rotation center axis of the distributor 4. The motor 31 is fixedly mounted on the housing 1. The output shaft of the motor 31 is connected to the drive shaft 32 to drive the drive shaft 32 to rotate. The drive shaft 32 is connected to the connector 35 to drive the connector 35 to swing. The connector 35 is further connected to the distributor 4. The connector 35 includes at least one of a cam and an eccentric wheel.

[0050] The connector 35 includes at least one of a cam and an eccentric wheel, so that in a plane perpendicular to the rotation center axis of the distributor 4, the connector 35 can drive the distributor 4 to swing, so that the distributor 4 can move away from and closer to the roller brush 2.

[0051] By setting the connection position between the connector 35 and the water distributor 4, the swing range of the water distributor 4 can be defined. In one embodiment, the angle corresponding to the swing range of the water distributor 4 does not exceed 15°. In another embodiment, the angle corresponding to the swing range of the water distributor 4 is 5° to 10°. In some embodiments, the angle corresponding to the swing range of the water distributor 4 is 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc.

[0052] As shown in Figure 6, the connecting part 35 is an eccentric wheel, which is eccentrically mounted on the drive shaft 32. Referring to Figures 3 and 4, a connecting part 4121 is provided on the side of the distributor 4 away from the roller brush 2. The connecting part 4121 is hinged to the eccentric wheel, and the central axis of the hinge is parallel to the rotational central axis of the distributor 4. Since the rotational central axis of the eccentric wheel is the same as the rotational central axis of the drive shaft 32, but there is a distance between the geometric center of the eccentric wheel and the rotational central axis, when the drive shaft 32 rotates, the eccentric wheel rotates with the drive shaft 32. The position on the eccentric wheel that is hinged to the connecting part 4121 rotates around the drive shaft 32. Because the connecting part 4121 is hinged to the eccentric wheel, the connecting part 4121, together with the entire distributor 4, reciprocates in a plane perpendicular to the rotational central axis of the distributor 4. This causes the distributor 4 to reciprocate.

[0053] In some embodiments, the connecting member 35 is a cam rotatably mounted on the drive shaft 32, and the cam is hinged to the connecting part 4121. The cam can convert the rotation of the drive shaft 32 into linear motion in a direction perpendicular to the rotation center of the drive shaft 32, so as to drive the connecting part 4121 to reciprocate in a plane perpendicular to the rotation center axis of the water distributor 4.

[0054] In some embodiments, referring to FIG6, the connector 35 is pivotally fitted onto the outside of the eccentric portion 321 of the drive shaft 32. The eccentric portion 321 of the drive shaft 32 rotates with the drive shaft 32, and the eccentric portion 321 of the drive shaft 32 rotates relative to the connector 35, so as to convert the rotational power into the movement of the connector 35 in a direction perpendicular to the rotational center axis of the drive shaft 32, so as to drive the connector 4121 to reciprocate in a plane perpendicular to the rotational center axis of the water distributor 4. The eccentric portion 321 of the drive shaft 32 is circumferentially limited to the shaft body of the drive shaft 32. As shown in FIG6, the shaft body of the drive shaft 32 has a non-circular profile in cross-section perpendicular to its rotational center axis to achieve circumferential limitation.

[0055] It should be noted that the water distributor 4 can be positioned close to or far from the roller brush 2; "close to" and "far from" are relative concepts. In the second position described above, there is a second distance between the water distributor 4 and the roller brush 2. In the first position described above, the water distributor 4 is positioned close to the roller brush 2, which includes the water distributor 4 being in contact with the roller brush 2, or having a first distance from the roller brush 2 that is less than the second distance.

[0056] In one embodiment, in a first position, the water distributor 4 is positioned to contact the roller brush 2.

[0057] The purpose of this design is that, since the outer periphery of the roller brush 2 is usually a soft absorbent layer, such as a multi-hair layer, in the first position, the edge of the water distributor 4 can apply a certain pressure to the absorbent layer, causing the water to disperse to the surrounding area, which in turn helps the water to spread and distribute evenly on the roller brush 2; on the other hand, the water distributor 4 itself can scrape off excess water on the roller brush 2, keeping the moisture content on the roller brush 2 close or even consistent, which is conducive to a uniform cleaning effect.

[0058] Referring further to Figure 6, in one embodiment, at least in the first position, the water distributor 4 floats against the roller brush 2 in the direction of rotation. Furthermore, as shown in Figure 7, the cleaning device 100 also includes a reset member 36, disposed between the housing 1 and the water distributor 4, for providing a force to continue deflecting the water distributor 4 toward the roller brush 2 when the water distributor 4 contacts the roller brush 2.

[0059] The floating drive of the first driving component 3 to the water distributor 4 can be achieved through the following scheme.

[0060] As shown in Figure 6, a pin 4122 is provided on the connecting part 4121, and a strip-shaped hole 350 is provided on the connecting member 35. The extending direction of the strip-shaped hole 350 is perpendicular to the rotation center axis of the water distributor 4. The pin 4122 can rotate and slide within the strip-shaped hole 350. When the first driving member 3 stops operating, for example, when the water distributor 4 abuts against the roller brush 2, the strip-shaped hole 350 provides space for the water distributor 4 to swing in a plane perpendicular to its rotation center axis. At this time, the reset member 36 causes the water distributor 4 to abut against the roller brush 2 with a certain pressure. The strip-shaped hole 350 can be an oblong hole, a rectangular hole, etc.

[0061] The purpose of this design is that the water distributor 4 can float against the roller brush 2. On the one hand, through the cooperation of the reset member 36 and the first driving member 3, the water distributor 4 can be pressed against the roller brush 2 with appropriate force, so that the water distribution effect will not be poor due to too light a pressing, nor will the water on the roller brush 2 be too little and the cleaning effect be poor due to too heavy a pressing. On the other hand, as the cleaning equipment 100 is used, the water absorption layer on the roller brush 2 will be worn away, and the elasticity of the roller brush 2 will deteriorate due to long-term pressure. At this time, with the force provided by the reset member 36, the water distributor 4 can still be reliably pressed against the roller brush 2 to ensure the uniformity of water distribution on the roller brush 2.

[0062] In other embodiments, it is also possible to interchange the positions of the slot 350 and the pin 4122.

[0063] The reset element 36 can be any component capable of providing a force toward the roller brush 2 to the distributor 4. In one embodiment, referring to Figure 7, the reset element 36 is an elastic element, which can be a spring or other elastic strip structure. In one embodiment, the reset element 36 may include two mutually exclusive permanent magnets (not shown), one permanent magnet being disposed on the side of the housing 1 facing the distributor 4, and the other permanent magnet being disposed on the side of the distributor 4 away from the roller brush 2.

[0064] Referring to Figures 2 and 3, in one embodiment, the roller brush 2 has a certain length, and the water distributor 4 also has a corresponding certain length to ensure that water can be sprayed onto all positions along the axial direction of the roller brush 2. Based on this, in order to drive the oscillation of the water distributor 4 more evenly and smoothly, the drive shaft 32 has a certain length, and the number of connecting pieces 35 and connecting parts 4121 is multiple, with the multiple connecting pieces 35 arranged at intervals along the axial direction of the drive shaft 32. In this way, the multiple connecting pieces 35 can provide multi-point drive for the water distributor 4, ensuring synchronous oscillation of the water distributor 4 at all points along the axial direction, and ensuring uniform water distribution along the axial direction of the roller brush 2. As shown in Figure 2, one end of the drive shaft 32 is used to connect to the motor 31, and the end of the drive shaft 32 away from the motor 31 can be provided with a bearing 320, which is mounted on the housing 1 to support the drive shaft 32.

[0065] In practical applications, an appropriate number of connectors 35 can be arranged according to the specific length and material of the roller brush 2. In some embodiments, the number of connectors 35 can be two or three. Depending on other needs, the number of connectors 35 can also be other numbers.

[0066] In the axial direction of the roller brush 2, the number of reset elements 36 can also be multiple, for example, two or three. The multiple reset elements 36 are distributed at intervals.

[0067] Referring to Figures 2 and 7, in one embodiment, the first driving member 3 may further include a meshing first gear 33 and a second gear 34. The first gear 33 is fixedly connected to the output shaft of the motor 31, and the second gear 34 is coaxial and fixedly connected to the drive shaft 32. The motor 31 drives the first gear 33 to rotate, which in turn drives the second gear 34, which in turn drives the drive shaft 32 to rotate. In this embodiment, the meshing of the teeth of the first gear 33 and the second gear 34 allows the drive shaft 32 to rotate at a smaller angular velocity, which also helps to improve the control accuracy of the swing angle of the water distributor 4.

[0068] In other embodiments, the motor 31 and the drive shaft 32 may be engaged by other forms of transmission components to achieve speed reduction.

[0069] Then, please refer to Figures 2, 3 and 6. The water distributor 4 includes a flow guide 41. The flow guide 41 has a through water guide channel 410. One end of the water guide channel 410 forms the above-mentioned water outlet 4101 and faces the roller brush 2. The other end of the water guide channel 410 has a water inlet 4102 for flexible communication with the clean water tank.

[0070] Referring to Figures 2, 4, and 5, in one embodiment, the water distributor 4 further includes a first scraper 42, which is fixedly connected to the flow guide 41 and swings synchronously with the swing of the flow guide 41. In a first position, at least the first scraper 42 is configured to abut against the roller brush 2. The flow guide 41 guides water from the clean water tank to the roller brush 2, and the first scraper 42 performs water distribution and scraping on the roller brush 2.

[0071] In the second position, both the first scraper 42 and the guide portion 41 are far away from the roller brush 2.

[0072] The first scraper 42 can be a rigid component, for example, a hard plastic scraper or a metal component. In some embodiments, the first scraper 42 can be a stainless steel scraper, etc.

[0073] As shown in Figures 4 and 6, the first scraper 42 is positioned at the lower end of the water distributor 4. This arrangement serves two purposes: First, in the first position, the first scraper 42 contacts the roller brush 2. Based on the rotation direction of the roller brush 2, the first scraper 42 can carry the water flowing from the water distributor 4, allowing the water to enter the roller brush 2 as much as possible and rotate upwards with it, further ensuring a uniform distribution of water on the roller brush 2. Third, based on the rotation direction of the roller brush 2, the first scraper 42 can also initially separate the wastewater on the roller brush 2 and block it below, thus isolating the clean water from the clean water tank from the wastewater on the roller brush 2. The wastewater is then further recycled to the wastewater tank via the suction assembly.

[0074] As shown in Figures 3, 6, and 7, the flow guiding section 41 includes a flow guiding body 411 and a rear cover plate 412 that are fixedly connected to each other. The flow guiding body 411 forms the aforementioned water guiding channel 410 and water outlet 4101. The rear cover plate 412 closes the side of the flow guiding body 411 away from the roller brush 2, and a water inlet 4102 is provided on the rear cover plate 412, which communicates with the clean water tank. The aforementioned connecting portion 4121 is formed on the rear cover plate 412. The flow guiding body 411 and the rear cover plate 412 are manufactured separately and then connected together, which facilitates the molding of each part. In some embodiments, the flow guiding body 411 and the rear cover plate 412 can be injection molded separately.

[0075] Referring to Figures 3 and 7, a receiving groove 4110 is formed on the side of the flow guide 41 facing away from the roller brush 2. A portion of the reset member 36 is located within the receiving groove 4110, while another portion is located outside the receiving groove 4110 and abuts against the housing 1. In this way, by limiting the reset member 36 with the receiving groove 4110, the connection and fixation between the reset member 36 and the flow guide 41 can be simplified.

[0076] The receiving groove 4110 can be formed on the flow guide body 411, and the rear cover plate 412 is provided with a clearance hole 4120 corresponding to the receiving groove 4110, as shown in Figure 3. The receiving groove 4110 is isolated from the water guide channel 410. In other embodiments, the receiving groove 4110 is provided on the rear cover plate 412 and is formed by a portion of the rear cover plate 412 being recessed towards the roller brush 2.

[0077] Referring to Figures 4, 7, and 8, in one embodiment, the cleaning device 100 further includes a second scraper 6, which is fixedly disposed on the housing 1. The second scraper 6 is located below the first scraper 42 and contacts the roller brush 2. Based on the rotation direction of the roller brush 2, the second scraper 6 contacts the roller brush 2 before the first scraper 42 and separates the sewage and garbage adhering to the roller brush 2.

[0078] Specifically, as shown in Figures 7 and 8, the lower end of the second scraper 6, facing the roller brush 2, is provided with a comb tooth portion 61. The comb tooth portion 61 includes a plurality of comb teeth spaced apart along the axial direction of the roller brush 2. The comb tooth portion 61 is used to insert into the multi-bristle layer of the roller brush 2 to scrape off and retain the debris attached to the roller brush 2.

[0079] On the cleaning device 100, a suction port 10 can be formed below the second scraper 6 (see Figures 10 and 11). The suction port 10 is connected to a sewage tank (not shown) provided on the housing 1 so that sewage, garbage and the like can enter the sewage tank.

[0080] The second scraper 6 can be a rigid scraper, such as a rigid plastic scraper or a metal scraper. The second scraper 6 can be fixed to the housing 1 by means of screws or other methods.

[0081] In one embodiment, referring to Figures 7 and 8, the cleaning device 100 further includes a seal 7. The seal 7 is fixedly disposed on the side of the second scraper 6 facing the first scraper 42, i.e., the upper side, and is used to make sealing contact with the surface of the first scraper 42 facing the second scraper 6, i.e., the lower surface of the first scraper 42. Due to the oscillation of the guide portion 41 and the first scraper 42, a gap is reserved between the lower surface of the first scraper 42 and the upper surface of the second scraper 6. The seal 7 is disposed here to prevent water, debris, etc., from entering the interior of the housing 1 through this gap.

[0082] As shown in Figures 6, 7, and 8, the seal 7 includes a first sealing portion 71, which abuts against the lower surface of the first scraper 42 to maintain a sealed connection with the lower surface of the first scraper 42 without interfering with the swinging motion of the first scraper 42. In both the first and second positions, the first sealing portion 71 abuts against the lower surface of the first scraper 42.

[0083] In one embodiment, as shown in Figure 8, the seal 7 further includes a second sealing portion 72, which is used to contact the surface of the roller brush 2. It is understood that, since the seal 7 is elastic and the absorbent layer on the surface of the roller brush 2 is also elastic, a certain pressure can exist between the second sealing portion 72 and the surface of the roller brush 2 to maintain a seal between them. This isolates garbage, sewage, etc., below the second sealing portion 72, facilitating the entry of sewage, garbage, etc., into the suction port 10.

[0084] Please refer to Figure 8 for details. The second scraper 6 has multiple mounting holes 60. The seal 7 also includes a mounting part 73 connected to the first sealing part 71 and the second sealing part 72. The mounting part 73 includes multiple protrusions 730, which are interference-fitted into the mounting holes 60, so that the seal 7 can be easily fixed to the second scraper 6. That is, the seal 7 is a structural component capable of elastic deformation, and its protrusions 730 are fixed in the mounting holes 60 in a way that allows for elastic deformation. The specific material of the seal 7 can be, but is not limited to, rubber, flexible plastic, silicone, etc.

[0085] In some embodiments, the seal 7 can be replaced by being fixed to the lower surface of the first scraper 42 by its mounting portion 73, the first sealing portion 71 abutting against and sealing the upper surface of the second scraper 6, and the second sealing portion 72 being able to remain in contact with the surface of the roller brush 2 during the swinging process.

[0086] In addition, please refer to Figures 9 to 11 for other implementations of the first drive element 3 to float drive the water distributor 4.

[0087] Please refer to Figure 9. The drive shaft 32 is coaxial and fixedly connected to the fourth gear 38. The third gear 37 meshes with the fourth gear 38. The water distributor 4 is coaxially mounted on the third gear 37 and can rotate within a certain range relative to the third gear 37. The reset member 36 is a compression spring, which is disposed between the water distributor 4 and the housing 1 to provide a force for the water distributor 4 to rotate towards the roller brush 2. Here, the angle at which the water distributor 4 can rotate relative to the third gear 37 is small. In some embodiments, the angle at which the water distributor 4 can rotate relative to the third gear 37 does not exceed 10°. In other embodiments, the angle at which the water distributor 4 can rotate relative to the third gear 37 is between 4° and 8°, serving as the rotational floating space of the water distributor 4 relative to the third gear 37. Based on the rotational floating of the water distributor 4 relative to the third gear 37, the force provided by the compression spring causes the water distributor 4 to abut against the roller brush 2.

[0088] Specifically, as shown in Figure 9, the third gear 37 is provided with a shaft portion 371 collinear with its rotation center axis. The shaft portion 371 is disposed within a shaft hole 45 on the water distributor 4. The circumferential width of the shaft hole 45 is greater than the circumferential width of the shaft portion 371, thereby allowing the water distributor 4 to rotate and float relative to the shaft portion 371 within a certain angular range. In some embodiments, the profile of the longitudinal section of the shaft hole 45 is greater than the profile of the longitudinal section of the shaft portion 371, and the longitudinal section is a section perpendicular to the rotation center axis of the third gear 37.

[0089] Referring to Figure 10, the drive shaft 32 is coaxial and fixedly connected to the fourth gear 38, the third gear 37 meshes with the fourth gear 38, one end of the connecting rod 39 is eccentrically and hingedly connected to the third gear 37, and the other end of the connecting rod 39 passes through the water distributor 4. A reset member 36 is provided between the water distributor 4 and the housing 1. In some embodiments, a compression spring is provided between the side of the water distributor 4 away from the roller brush 2 and the housing 1, and the compression spring is the reset member 36. When the third gear 37 rotates under the drive of the fourth gear 38, the connecting rod 39 can drive the water distributor 4 to swing, and the compression spring makes the water distributor 4 float against the roller brush 2.

[0090] Please refer to Figure 11. Connector 35 is an eccentric wheel, drive shaft 32 is connected to the eccentric wheel, one end of connecting rod 39 is hinged to the eccentric wheel, and the other end of connecting rod 39 passes through the distributor 4. A reset member 36 is provided between the side of the distributor 4 facing away from the roller brush 2 and the housing 1. In some embodiments, a compression spring is provided between the side of the distributor 4 facing away from the roller brush 2 and the housing 1, and the compression spring is the reset member 36. When the eccentric wheel rotates, connecting rod 39 drives the distributor 4 to swing, and the compression spring causes the distributor 4 to float against the roller brush 2.
