[0054] In order to illustrate the technical scheme described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0055] The embodiment of the present application provides a cleaning device 100, which is used for cleaning the ground.

[0056] Please refer to Figure 1 and Figure 2As shown, 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. Both the first drive member 3 and the water distributor 4 are mounted on the housing 1. The first drive member 3 is connected to the water distributor 4 and drives the water distributor 4 to move, so that at least the outlet 4101 of the water distributor 4 can be at least in a first position near the roller brush 2 (see reference). Figure 4 (as shown) and the second position away from brush 2 (see...) Figure 5 Switch between (as shown).

[0057] like Figure 1 and Figure 2 As shown, the side of the water distributor 4 facing away from the roller brush 2 (see [reference]). Figure 3 The inlet 4102 shown 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 distributor 4, wetting the roller brush 2. The distributor 4 has multiple outlets 4101 distributed on the side facing the roller brush 2; please refer to [reference needed]. Figure 6 As shown.

[0058] like Figure 4 As shown, in the first position, the water distributor 4 is positioned close to the roller brush 2. At 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. This improves the uniformity of spraying across the surface of the roller brush 2, which is suitable for routine floor cleaning, ensuring even cleaning and preventing uncleaned areas or residual moisture. Figure 5 As shown, in the second position, the water distributor 4 is positioned away from the roller brush 2. At this time, the water distributor 4 can quickly wet the ground and the roller brush 2. It is suitable for use in scenarios that require quick cleaning or preliminary cleaning, such as when there are many stains on the ground and the cleaning equipment 100 needs to quickly clean and preliminarily clean the stains on the ground. Since the water distributor 4 is away from the roller brush 2, some water can be sprayed directly onto the ground, which can quickly wet the ground.

[0059] For some floor materials, such as smooth and poorly absorbent materials like tiles and wood, the water distributor 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.

[0060] The cleaning device 100 in this application 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.

[0061] 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.

[0062] In some embodiments, the cleaning device 100 can further comprise a clean water tank, a dirty water tank, a water spraying assembly, a dirty water suction assembly, etc. (all not shown) disposed in the housing 1, the clean water tank is connected with the water distributor 4 through the pipe 8, the water spraying assembly is disposed on the housing 1 and is used to provide power for the clean water from the clean water tank to the water distributor 4, the dirty water tank is in communication with the dirty water suction port 10, and the dirty water suction assembly is disposed on the housing 1 and is used to provide power for the dirty water, garbage, etc. to enter the dirty water tank.

[0063] In some embodiments, taking the self-walking cleaning device as an example, the cleaning device 100 further comprises a walking assembly disposed at the bottom of the housing 1 and a second driving member disposed in the interior of the housing 1 (both not shown), and the second driving member is used to drive the walking assembly.

[0064] Please refer to Figure 4 and Figure 5 In one embodiment, the water distributor 4 is rotatably disposed on the housing 1, and the rotational center axis of the water distributor 4 is parallel to the rotational center axis of the rolling brush 2. Figure 4 and Figure 5 In the figures, the dotted arc arrow represents the rotation direction of the water distributor 4, and the dash-dot arc arrow represents the rotation direction of the rolling brush 2. The first driving member 3 is used to drive the water distributor 4 to rotate, so that the water distributor 4 can rotate to approach and move away from the rolling brush 2.

[0065] In one optional embodiment, in the vertical direction, the rotational center axis of the water distributor 4 is disposed at the upper end of the water distributor 4, that is, the water outlet 4101 of the water distributor 4 is lower than the rotational center axis thereof. Please refer to Figure 4 and Figure 5 In the figures, the water distributor 4 has different angles relative to the vertical direction in the first position and the second position. From the first position to the second position, the water outlet 4101 of the water distributor 4 is deflected downward by a certain angle, so that in the second position, the water flowing out of the water distributor 4 is more likely to flow downward, and a part of the water can be allowed to directly flow onto the ground.

[0066] It should be noted that the “upper” and “lower” used in the above and below are based on the orientation of the cleaning device 100 in the working state. In the non-working state, the cleaning device 100 can have other orientations, but it does not affect the relative positional relationship between the components in the cleaning device 100.

[0067] Without limitation, in other optional embodiments, the rotational center axis of the water distributor 4 can also be disposed higher than or flush with the water outlet 4101 of the water distributor 4, if allowed.

[0068] Specifically, please refer to Figure 4 to Figure 6As shown, the first driving member 3 comprises a motor 31, a driving shaft 32 and a connecting member 35 connected in sequence, the rotating central axis of the driving shaft 32 and the connecting member 35 is parallel to the rotating central axis of the water distributor 4, the motor 31 is fixedly arranged on the housing 1, the output shaft of the motor 31 is connected with the driving shaft 32 for driving the driving shaft 32 to rotate, the driving shaft 32 is connected with the connecting member 35 for driving the connecting member 35 to swing, and the connecting member 35 is further connected with the water distributor 4. The connecting member 35 comprises at least one of a cam and an eccentric wheel.

[0069] The connecting member 35 comprises at least one of a cam and an eccentric wheel, so that the connecting member 35 can drive the water distributor 4 to swing in a plane perpendicular to the rotating central axis of the water distributor 4, so that the water distributor 4 can move away from and close to the roller brush 2.

[0070] The connecting position between the connecting member 35 and the water distributor 4 can limit the swing range of the water distributor 4. For example, in one embodiment, the swing range of the water distributor 4 corresponds to an angle of not more than 15°, and further, the swing range of the water distributor 4 corresponds to an angle of 5°-10°. In some specific embodiments, the swing range of the water distributor 4 corresponds to an angle of 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc.

[0071] As shown in Figure 6 The connecting member 35 is an eccentric wheel, which is arranged on the driving shaft 32 in an eccentric manner, please refer to Figure 3 and Figure 4 The side of the water distributor 4 away from the roller brush 2 is provided with a connecting portion 4121, the connecting portion 4121 is hingedly connected with the eccentric wheel, and the central axis of the hinge is parallel to the rotating central axis of the water distributor 4. Since the rotating central axis of the eccentric wheel is the rotating central axis of the driving shaft 32, but there is a distance between the geometric center of the eccentric wheel and the rotating central axis, when the driving shaft 32 rotates, the eccentric wheel rotates with the driving shaft 32, and the position of the eccentric wheel hingedly connected with the connecting portion 4121 rotates around the driving shaft 32. Since the connecting portion 4121 is hingedly connected with the eccentric wheel, the connecting portion 4121 together with the entire water distributor 4 performs reciprocating swing in a plane perpendicular to the rotating central axis of the water distributor 4. In this way, the water distributor 4 is driven to reciprocating swing.

[0072] In other optional embodiments, the connecting member 35 is a cam rotatably arranged on the driving shaft 32, and the cam is hingedly connected with the connecting portion 4121. The cam can convert the rotation of the driving shaft 32 into a linear motion in a direction perpendicular to the rotating central direction of the driving shaft 32, so as to drive the connecting portion 4121 to reciprocating swing in a plane perpendicular to the rotating central axis of the water distributor 4.

[0073] 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.

[0074] In one alternative embodiment, in a first position, the water distributor 4 is positioned to contact the roller brush 2.

[0075] 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.

[0076] Please refer to further information. Figure 6 As shown, in one optional embodiment, at least in the first position, in the rotation direction of the water distributor 4, the water distributor 4 is floating against the roller brush 2. And, as... Figure 7 As shown, the cleaning device 100 also includes a reset member 36, which is disposed between the housing 1 and the water distributor 4, and is used to provide a force for the water distributor 4 to continue to deflect toward the roller brush 2 when the water distributor 4 contacts the roller brush 2.

[0077] The floating drive of the first driving component 3 to the water distributor 4 can be achieved through the following scheme.

[0078] like Figure 6 As shown, the connecting part 4121 is provided with a pin 4122, and the connecting member 35 is provided with a strip-shaped hole 350. The extension 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 setting of 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 specifically be an oblong hole, a rectangular hole, etc.

[0079] The purpose of such arrangement is that the water distributor 4 is abutted against the rolling brush 2 in a floating manner. On one hand, through the cooperation of the reset member 36 and the first driving member 3, the water distributor 4 is abutted against the rolling brush 2 with a proper force, so that the water distribution is not poor due to too light abutment, and the cleaning effect is not poor due to too heavy abutment. On the other hand, with the use of the cleaning device 100, the water absorption layer on the rolling brush 2 is worn out, the rolling brush 2 is poor in elasticity due to long-term compression, and the like. At this time, the water distributor 4 can still be reliably abutted against the rolling brush 2 by the force provided by the reset member 36, so as to ensure the uniformity of water distribution on the rolling brush 2.

[0080] In other optional embodiments, the bar-shaped hole 350 and the pin shaft 4122 can be arranged in an exchanged position.

[0081] The reset member 36 can be any component capable of providing a force to the water distributor 4 towards the rolling brush 2. For example, in one embodiment, as shown in Figure 7 , the reset member 36 is an elastic member, which can be a spring or other elastic strip structure. For another example, the reset member 36 can include two mutually repulsive permanent magnets (not shown), one of which is arranged on the side of the shell 1 facing the water distributor 4, and the other of which is arranged on the side of the water distributor 4 away from the rolling brush 2.

[0082] As shown in Figure 2 and Figure 3 , in one embodiment, the rolling brush 2 has a certain length, and the water distributor 4 also has a certain length to ensure that water can be sprayed to all positions in the axial direction of the rolling brush 2. On this basis, in order to more balancedly and stably drive the oscillation of the water distributor 4, the driving shaft 32 is arranged to have a certain length, the number of the connecting members 35 and the connecting portions 4121 is multiple, and the multiple connecting members 35 are arranged in an interval along the axial direction of the driving shaft 32. In this way, the multiple connecting members 35 can provide multi-point driving to the water distributor 4, so as to ensure the synchronous oscillation of the water distributor 4 at all positions in the axial direction and ensure the uniform distribution of water at all positions in the axial direction of the rolling brush 2. As shown in Figure 2 , one end of the driving shaft 32 is used to connect the motor 31, and the end of the driving shaft 32 away from the motor 31 can be provided with a bearing 320, which is installed on the shell 1 to support the driving shaft 32.

[0083] In specific applications, a proper number of connecting members 35 can be arranged according to the specific length and material of the rolling brush 2, for example, the number of the connecting members 35 can be two or three. According to other needs, the number of the connecting members 35 can also be other numbers.

[0084] In the axial direction of the rolling brush 2, the number of the reset members 36 can also be multiple, for example, two or three, and the multiple reset members 36 are arranged in an interval.

[0085] Please refer to Figure 2 and Figure 7 As shown in the figures, in one embodiment, the first driving member 3 can further include a first gear 33 and a second gear 34 engaged with each other, the first gear 33 is fixedly connected with the output shaft of the motor 31, and the second gear 34 is coaxial with and fixedly connected with the driving shaft 32. The motor 31 drives the first gear 33 to rotate, the first gear 33 drives the second gear 34 to rotate, and the second gear 34 drives the driving shaft 32 to rotate. In this embodiment, through the matching of the number of teeth of the first gear 33 and the second gear 34, the driving shaft 32 can rotate at a smaller angular velocity, which is also conducive to improving the control accuracy of the swing angle of the water distributor 4.

[0086] Without being limited to the above, in other optional embodiments, the motor 31 and the driving shaft 32 can be connected through other forms of transmission members to realize speed reduction matching.

[0087] Then, please refer to Figure 2 , Figure 3 and Figure 6 As shown in the figures, the water distributor 4 includes a flow guide part 41, the flow guide part 41 is provided with a water guide channel 410 penetrating through it, one end of the water guide channel 410 forms the water outlet 4101 described above and faces the roller brush 2, and the other end of the water guide channel 410 is provided with a water inlet 4102 for flexible communication with the clean water tank.

[0088] Please refer to Figure 2 , Figure 4 and Figure 5 In one embodiment, the water distributor 4 further includes a first scraping strip 42, the first scraping strip 42 is fixedly connected with the flow guide part 41 and synchronously swings with the flow guide part 41, and in the first position, at least the first scraping strip 42 is configured to abut against the roller brush 2. The flow guide part 41 is used to guide water from the clean water tank to the roller brush 2, and the first scraping strip 42 is used to even water and scrape water on the roller brush 2.

[0089] In the second position, the first scraping strip 42 and the flow guide part 41 are both away from the roller brush 2.

[0090] The first scraping strip 42 can be a rigid member, for example, it can be a hard plastic scraping strip, or a metal member, specifically a stainless steel scraping strip, etc.

[0091] Optionally, as shown in Figure 4 and Figure 6As shown, the first scraping strip 42 is arranged at the lower end of the water distributor 4. The purpose of such arrangement is that, in the first position, the first scraping strip 42 is in contact with the roller brush 2, and based on the rotating direction of the roller brush 2, the first scraping strip 42 can carry the water flowing out of the water distributor 4 so that the water enters the roller brush 2 as much as possible and rotates upward with the roller brush 2, which can further ensure the uniform distribution of water on the roller brush 2; thirdly, based on the rotating direction of the roller brush 2, the first scraping strip 42 can also preliminarily separate the sewage on the roller brush 2 and block the sewage below, so that the clean water from the clean water tank and the sewage on the roller brush 2 are isolated from each other, and the sewage is further recycled to the sewage tank through the sewage suction assembly.

[0092] As shown in Figure 3 , Figure 6 and Figure 7 , the flow guide part 41 comprises a flow guide body 411 and a back cover plate 412 which are fixedly connected, the flow guide body 411 is used to form the water guide channel 410 and the water outlet 4101 described above, the back cover plate 412 closes the side of the flow guide body 411 away from the roller brush 2, and the back cover plate 412 is provided with the water inlet 4102 which is in communication with the clean water tank, and the back cover plate 412 forms the connecting part 4121 described above. The flow guide body 411 and the back cover plate 412 are manufactured separately and connected together, which is convenient for respective molding. For example, the flow guide body 411 and the back cover plate 412 can be injection molded respectively.

[0093] As shown in Figure 3 and Figure 7 , the side of the flow guide part 41 away from the roller brush 2 forms a containing groove 4110, part of the reset member 36 is located in the containing groove 4110, and the other part is located outside the containing groove 4110 and abuts against the shell 1.
