Description

Technical Field

[0001] The invention relates to the technical field of cleaning appliances, in particular to a floor brush structure and a cleaning device. Background Art

[0002] With the development of technology, various cleaning equipment has emerged, such as floor scrubbers. Floor scrubbers can assist manual cleaning work and bring convenience to daily work and life. Floor scrubbers can spray water on the roller brush, use the rotating roller brush to wipe off the stains on the surface to be cleaned, and then use the suction flow to remove the stains and sewage.

[0003] However, in actual use, the wet roller brush often leaves strips of water stains after rolling on the ground, and the water stains are relatively high. At the same time, when encountering relatively sticky stains or hair, the scraper bar on the floor scrubber can hardly remove the stains stuck on the roller brush or the hair entangled in the roller brush, resulting in a poor user experience. Summary of the invention

[0004] In view of the above problems, the embodiments of the present disclosure provide a floor brush structure and a cleaning device.

[0005] A first aspect of the present disclosure provides a floor brush structure, the floor brush structure comprising:

[0006] Roller brush;

[0007] A liquid distributor, the liquid distributor is provided with a first liquid outlet, and the liquid distributor is configured to apply a cleaning medium to the roller brush;

[0008] The interference structure comprises: a first interference member and a second interference member; the first interference member is located at the upper side of the first liquid outlet hole, and the second interference member is located at the lower side of the first liquid outlet hole;

[0009] When the roller brush rotates counterclockwise, both the first interference member and the second interference member are in contact with the roller brush, and the interference amount between the first interference member and the roller brush is smaller than the interference amount between the second interference member and the roller brush;

[0010] Under the action of external force, the liquid distributor can move relative to the rolling brush to change the interference between the first interference member, the second interference member and the rolling brush.

[0011] The first interference member can block the cleaning medium from above. If the roller brush rotates counterclockwise, the first interference member can block the droplets thrown out by the centrifugal force of the roller brush, reducing the cleaning medium from falling to the ground. Therefore, the first interference member has the effect of reducing the generation of water stains and improving the cleaning effect.

[0012] After the liquid dispenser applies the cleaning medium, the cleaning medium squeezed out by the first interference member is blocked by the second interference member and will not easily drip onto the ground to form water stains.

[0013] Since both the first interference member and the second interference member are in contact with the roller brush, the cleaning medium can be temporarily stored between the first interference member and the second interference member, and this part of the cleaning medium still remains in contact with the roller brush. Under the action of gravity or the inertia generated by the rotation of the roller brush, the cleaning medium temporarily stored between the first interference member and the second interference member will flow to the area with less cleaning medium in the roller brush and be reabsorbed by the roller brush. Therefore, the cooperation of the first interference member and the second interference member can also improve the phenomenon of water stain residue and improve the cleaning effect.

[0014] When the roller brush rotates counterclockwise, the possibility of the cleaning medium being squeezed off by the first interference member can be reduced by using the small interference amount of the first interference member on the roller brush. At the same time, the cleaning medium will be gathered to a certain height on the upstream side of the first interference member (referring to the side of the first interference member facing the second interference member), so that the height of the cleaning medium on the upstream side of the first interference member is greater than the height of the cleaning medium on the downstream side of the first interference member (referring to the opposite side of the upstream side), so that under the action of the liquid height difference and the rotation of the roller brush, the cleaning medium is more likely to flow to the downstream side with a lower cleaning medium content, thereby achieving a uniform liquid effect.

[0015] The liquid uniforming effect of the first interference member is also reflected in that the cleaning medium will flow along the axial direction of the roller brush under the guidance of the first interference member, and will not gather in a small area of ​​the roller brush.

[0016] When the roller brush rotates in the counterclockwise direction, the larger interference amount of the second interference member on the roller brush can effectively squeeze out the liquid on the roller brush and separate the dirt from the roller brush.

[0017] When the liquid distributor moves, it can drive the interference structure to move, adjust the distance between different interference parts and the roller brush, and achieve different interference amounts between different interference parts and the roller brush. In addition, the liquid distributor can also adjust the distance between the same interference part and the roller brush by driving the interference structure to move, and achieve different interference amounts between the same interference part and the roller brush. Therefore, using the liquid distributor to drive the interference structure to move can improve the problem of the interference amount between the interference structure and the roller brush decreasing due to the wear of the roller brush.

[0018] In other words, the solution of the present application can achieve both better water uniformity and better dirt scraping effect, and it can also ensure that after the roller brush has been used for a long time and the diameter of the roller brush has changed, it can still achieve almost the same effect as before the change.

[0019] Optionally, the first interference member and the second interference member are respectively connected to the liquid distributor and are respectively located at the upper and lower sides of the first liquid outlet.

[0020] The first interference member and the second interference member are both connected to the liquid distributor, which can effectively ensure that the movement of the liquid distributor drives the two interference members to move at the same time. Moreover, the interference amount between the two interference members and the roller brush can be adjusted without adjusting the movement of the two interference members separately, which can reduce the structural complexity of the floor brush structure and the complexity of operating the interference structure. Moreover, the positions of the liquid distributor and the interference structure will be different. After the two are connected, in addition to directly acting on the interference structure to make the interference structure and the liquid distributor move together, the external force can also be applied to the liquid distributor to achieve the movement of the liquid distributor driving the interference structure to move. The first interference member and the second interference member are respectively connected to the liquid distributor, which can make the method of adjusting the interference amount between the interference structure and the roller brush more flexible.

[0021] Optionally, the roller brush comprises a roller shaft and a roller cloth, and the roller cloth covers the outer circumferential surface of the roller shaft;

[0022] When the roller brush rotates counterclockwise, both the first interference member and the second interference member are in contact with the roller cloth; and the distance between the second interference member and the roller shaft is 1 mm to 2.5 mm.

[0023] It should be understood that the interference between the second interference member and the roller will directly affect the scraping effect. When the distance between the second interference member and the roller is too short, the scraping effect will be greatly reduced. When the distance between the second interference member and the roller is too long, the second interference member may interfere with the roller or directly damage the roller bristles. Therefore, the distance in the present application can ensure the dirt scraping effect and also avoid the situation where the second interference member affects the life of the bristles.

[0024] Optionally, when the roller brush rotates counterclockwise, the distance between the first interference member and the roller axis satisfies the following relationship: x2=x1+D;

[0025] Wherein, x2 represents the distance between the first interference member and the roller, x1 represents the distance between the second interference member and the roller, D is a constant, and 0.5 mm≤D≤2.5 mm.

[0026] It has been mentioned above that when the first interference member and the second interference member rotate in the counterclockwise direction, they are both in contact with the roller brush. When rotating in the counterclockwise direction, the interference between the second interference member and the roller brush is greater, while the first interference member is also in contact with the roller brush. At this time, the first interference member has the effect of uniform water distribution.

[0027] In other words, if the interference between the first interference piece and the roller brush is too large, it will become a scraper and it will be impossible to evenly distribute the water. Therefore, when the interference between the second interference piece and the roller brush is large, the value of the interference between the first interference piece and the roller brush is very important. The above formula provided in the present application can directly obtain the interference between the first interference piece and the roller brush according to the interference between the second interference piece and the roller brush, so that the second interference piece and the first interference piece can achieve optimal usage.

[0028] Optionally, the roller brush is covered with a plurality of bristles, and when the roller brush rotates in a clockwise direction, the first interference member flips up the bristles.

[0029] When the roller brush rotates clockwise, the bristles first contact the first interference member, and the fallen bristles are turned up under the blocking effect of the first interference member to form upright bristles. Since the bristles have a certain "rigidity", the turned up bristles will still maintain a good upright state when the roller brush continues to rotate to the ground, and the "rigidity" of the bristles can apply greater positive pressure to the ground and stains. Therefore, the roller brush rotating clockwise can achieve a better cleaning effect on stubborn stains.

[0030] When the roller brush rotates clockwise, the bristles are turned up, and the amount of liquid stored in the bristles is more than when it is turned down. The liquid recovery rate on the roller brush is reduced, and more liquid will flow to the ground. This part of the liquid flowing to the ground can soften the stains, making them easier to remove, and can assist in cleaning stubborn stains, further improving the cleaning effect.

[0031] Optionally, when the roller brush is rotated in a clockwise direction, the interference between the first interference member and the roller brush is greater than the interference between the second interference member and the roller brush.

[0032] When the roller brush is rotated in the clockwise direction, the interference between the first interference piece and the roller brush is large, which can turn the bristles up to a higher upright state, ensuring that the bristles still maintain good "rigidity" when they reach the ground. The first interference piece can also squeeze out the dirt on the roller brush, playing a role in separating sewage and solid dirt. The second interference piece with a smaller interference with the roller brush can not only reduce the obstruction of the dirt scraped off by the first interference piece, but also assist in turning the bristles.

[0033] The larger interference fit between the first interference member and the roller brush can separate the dirt more cleanly.

[0034] Optionally, when the roller brush rotates in a clockwise direction, both the first interference member and the second interference member are in contact with the roller cloth; and the distance between the first interference member and the roller shaft is 1 mm to 2.5 mm.

[0035] The above scheme can also refer to the above description, and the distance between the first interference member and the roller can also be used to indirectly determine the interference between the first interference member and the roller brush, while both can meet the user experience.

[0036] Optionally, the movement of the liquid distributor relative to the roller brush includes rotation or linear motion;

[0037] When the liquid distributor is configured to rotate, when the roller brush rotates in a counterclockwise direction, the liquid distributor drives the interference structure to rotate in a direction opposite to the direction when the roller brush rotates in a clockwise direction.

[0038] The liquid distributor can adjust the interference amount between the interference structure and the roller brush by rotating or linear motion, and the movement mode is more flexible. When the liquid distributor is configured to rotate, the interference structure rotates in the opposite direction when the roller brush rotates counterclockwise and clockwise. This swinging rotation method can adjust the interference amount between the interference structure and the roller brush at a smaller rotation angle. This swinging method can reduce the occupation of the internal space of the floor brush structure and the interference with other components in the floor brush structure due to large-angle rotation.

[0039] Optionally, the interference structure and the liquid dispenser are split structures, and the interference structure is connected to the liquid dispenser in a fixed manner or a detachable manner; or, the interference structure and the liquid dispenser are integral structures.

[0040] The interference structure and the liquid distributor can be either a split structure or an integral structure, which is highly flexible. When the interference structure and the liquid distributor are an integral structure, at least the assembly steps of the interference structure and the liquid distributor can be saved, which facilitates the assembly and maintenance of the floor brush structure.

[0041] Optionally, the first interference member and the second interference member are split structures, and the first interference member and the second interference member are respectively connected to the dispenser in a fixed manner or a detachable manner; or, the first interference member and the second interference member are integral structures and connected to the dispenser.

[0042] The first interference member and the second interference member can be a split structure or an integral structure, making the design of the interference structure more flexible. When the interference structure is an integral structure, at least the assembly steps of the first interference member and the second interference member can be saved, which facilitates the assembly of the interference structure and the liquid dispenser.

[0043] Optionally, the first interference member is disposed at the upper end of the liquid dispenser and connected to the upper end surface of the liquid dispenser, and the second interference member is disposed at the lower end of the liquid dispenser and connected to the lower bottom surface of the liquid dispenser.

[0044] The first interference member and the second interference member are respectively connected to the upper and lower end surfaces of the liquid distributor, so that the distance between the first interference member and the second interference member is larger. The larger distance can not only reserve more space for the first liquid outlet, but also effectively increase the coverage area of ​​the cleaning medium applied to the roller brush through the first liquid outlet, thereby making the distribution of the cleaning medium on the roller brush more uniform.

[0045] Optionally, the first interference member extends obliquely upwardly toward the axis of the roller brush.

[0046] When the roller brush rotates clockwise, the first interference member extending upwardly and obliquely toward the axis of the roller brush can be opposite to the original inclination direction of the bristles, thereby more conveniently turning up the bristles. When the roller brush rotates counterclockwise, the first interference member extending upwardly and obliquely will not affect the rotation of the roller brush, and can also make the liquid on the roller brush more evenly distributed by smoothing.

[0047] Optionally, the second interference member extends obliquely downwardly toward below the axis of the roller brush.

[0048] When the roller brush rotates counterclockwise, the second interference member extending obliquely downward can guide the dirt squeezed out by it, and the interference between the second interference member extending obliquely downward and the roller brush is increased, so that the dirt can be scraped off more easily.

[0049] Optionally, the first interference member and the second interference member are spaced apart from each other, and the liquid dispenser is located between the first interference member and the second interference member.

[0050] When the first interference member and the second interference member are of a split structure, the interval between the first interference member and the second interference member can reserve installation space for the liquid distributor so as to directly apply the cleaning medium to the roller brush through the first liquid outlet.

[0051] Optionally, the interference structure also includes a connecting portion located between the first interference member and the second interference member, the liquid distributor is connected to the side of the connecting portion facing away from the roller brush, the connecting portion has a second liquid outlet for the cleaning medium to pass through, and the first liquid outlet of the liquid distributor is connected to the second liquid outlet.

[0052] When the first interference member and the second interference member are an integral structure, the connecting portion is a part of the interference structure, and the connecting portion can be used as a carrier for installing the dispenser and as a component of a fluid channel for applying a cleaning medium to the dispenser.

[0053] Optionally, the interference structure moves with the rotation of the roller brush, thereby changing the interference amount between the interference structure and the roller brush.

[0054] Using the rotation of the roller brush to drive the interference structure to rotate not only improves the utilization rate of the roller brush, but also eliminates the need for additional drive components to drive the interference structure to rotate, that is, the interference adjustment can be adaptively adjusted according to the rotation of the roller brush.

[0055] Optionally, the floor brush structure further includes a first driving assembly, and the first interference member and the second interference member move under the driving action of the first driving assembly.

[0056] The source of driving force for driving the interference structure may also be a first driving component independent of the roller brush, so that the rotation of the roller brush and the movement of the interference structure can be controlled separately, which is conducive to the refined design of the movement trajectory of the interference structure.

[0057] Optionally, the floor brush structure further includes: a roller brush cover assembly located above the roller brush, the liquid distributor and the interference structure are connected to the roller brush cover assembly, and the interference structure can be displaced under the action of an external force to change the interference amount.

[0058] The existing roller brush cover assembly in the floor brush structure is used to provide a mounting carrier for the interference structure and the liquid distributor, and there is no need to set up an additional carrier to mount the interference structure and the liquid distributor, thereby reducing the occupied space.

[0059] Optionally, the roller brush cover assembly comprises a movable first roller brush cover, and the first roller brush cover can be switched between a first position and a second position relative to the roller brush;

[0060] The first roller brush cover is connected to the interference structure and the liquid distributor, so that the first roller brush cover drives the liquid distributor to move under the action of the movement, thereby adjusting the interference between the first interference member, the second interference member and the roller brush respectively.

[0061] The first roller brush cover can be switched between the first position and the second position to achieve separation or contact between the first roller brush cover and the roller brush. Since the first roller brush cover is used to block the liquid or dirt thrown out when the roller brush rotates, when the first roller brush cover contacts the roller brush, the rotating roller brush can clean the dirt on the inner wall of the first roller brush cover. When the interference structure is connected to the first roller brush cover, the movement of the first roller brush cover can be used to drive the movement of the interference structure and the liquid dispenser, without the need to set up additional drive components for the interference structure and the liquid dispenser, thus achieving multiple goals at one stroke.

[0062] Optionally, the floor brush structure further includes:

[0063] A second driving assembly, wherein the second driving assembly is configured to drive the first roller brush cover to move.

[0064] The second driving component is used to drive the first roller brush cover to switch between the first position and the second position, and drives the interference structure and the liquid dispenser to move through the first roller brush cover, thereby realizing two uses of one driving component.

[0065] Optionally, the floor brush structure further comprises: a shell, the roller brush being rotatably connected to the shell;

[0066] The roller brush cover assembly further includes: a second roller brush cover, which is connected to the housing and has a gap with the roller brush, and the first roller brush cover is located in the gap between the second roller brush cover and the roller brush.

[0067] The second roller brush cover protects the first roller brush cover and can provide a carrier for the installation of the first roller brush cover.

[0068] Optionally, the roller brush cover assembly includes a first roller brush cover, and the liquid distributor is rotatably arranged on the inner side of the first roller brush cover so that the first interference member and the second interference member contact the roller brush. When the roller brush rotates, the liquid distributor can be driven to rotate to adjust the interference between the first interference member and the second interference member and the roller brush.

[0069] In addition to using the first roller brush cover to drive the interference structure and the liquid dispenser to move, the contact between the roller brush and the interference structure can also be used to drive the interference structure to rotate. Among them, the movement of the first roller brush cover and the movement of the interference structure can be unrelated, that is, the two move independently. Alternatively, the rotating roller brush can also be used to drive the interference structure and the liquid dispenser to rotate, and then the interference structure and the liquid dispenser can drive the first roller brush cover to move.

[0070] Optionally, the floor brush structure further includes an air duct, and the interference structure and the liquid distributor are located above the air duct and connected to the housing of the floor brush structure.

[0071] The interference structure and the liquid distributor are located above the air duct, so that the dirt scraped off by the interference structure can be sucked away by the air duct in time when it falls due to gravity, thereby ensuring the cleaning effect.

[0072] Optionally, the floor brush structure further includes a roller brush cover assembly, the liquid distributor is arranged below the roller brush cover assembly, and a first elastic member is arranged between the roller brush cover assembly and the first interference member, and when the liquid distributor moves, the first elastic member is deformed accordingly.

[0073] The elastic deformation characteristics of the elastic member can be used to block the interval between the roller brush cover assembly and the first interference member, eliminating the sanitary dead corner above the first interference member. In addition, the elastic deformation characteristics of the elastic member can adapt to the movement of the dispenser and the interference structure, ensuring the smoothness of the movement of the interference structure and the dispenser.

[0074] Optionally, the floor brush structure also includes: a cleaning nozzle and a roller brush cover assembly, the cleaning nozzle and the liquid distributor are both arranged below the roller brush cover assembly, the cleaning nozzle is connected to the liquid distributor to spray the cleaning medium from the liquid distributor between the interference structure and the roller brush cover assembly.

[0075] The cleaning medium sprayed by the cleaning nozzle can remove the dirt that may remain in the interval space between the roller brush cover assembly and the first interference member.

[0076] Optionally, the floor brush structure also includes: a first limit member and a second limit member respectively located on the upper and lower sides of the interference structure, and the interference structure abuts against the first limit member after moving upward by a first displacement to limit the interference structure from continuing to move upward; and the interference structure abuts against the second limit member after moving downward by a second displacement to limit the interference structure from continuing to move downward.

[0077] The first limiter is used to limit the maximum distance the interference structure can move upward, and the second limiter is used to limit the maximum distance the interference structure can move downward. This ensures that the movement range of the interference structure is controllable, thereby ensuring that the interference between the corresponding interference member and the roller brush meets the expected requirements.

[0078] Optionally, the housing comprises:

[0079] Upper shell;

[0080] A lower shell, wherein an air duct is provided between the upper shell and the lower shell;

[0081] A bracket is connected to the lower shell and is located above the air duct. The bracket is configured to carry the interference structure and the liquid dispenser. The interference structure and the liquid dispenser are rotatably embedded between the upper shell and the bracket.

[0082] After the interference structure and the liquid distributor are installed on the lower shell, covering the upper shell can not only realize the connection between the upper shell and the lower shell, but also limit the interference structure and the liquid distributor, at least facilitating the assembly of the floor brush structure.

[0083] Optionally, the floor brush structure further includes: a third driving assembly and a rotating shaft, wherein the third driving assembly and the rotating shaft are both connected to the liquid distributor, and the first interference member and the second interference member are both connected to the liquid distributor and are respectively located at the upper and lower sides of the first liquid outlet;

[0084] The liquid distributor can rotate around the rotating shaft under the action of external force to adjust the interference between the first interference member and the roller brush and the interference between the second interference member and the roller brush; and the liquid distributor can move toward the roller brush under the driving action of the third driving component to keep the interference between the first interference member and the roller brush within a first preset range and the interference between the second interference member and the roller brush within a second preset range.

[0085] The external force driving the liquid distributor and the interference structure to move may be independent of the third driving component. The third driving component is used to drive the interference structure and the liquid distributor to approach the roller brush alone, so as to maintain the interference between the first interference member and the second interference member and the roller brush, and reduce the influence caused by the insufficient interference between the interference structure and the roller brush due to the reduction of the diameter of the roller brush due to wear.

[0086] Optionally, when the liquid distributor is configured to move linearly, when the roller brush rotates counterclockwise, the liquid distributor drives the interference structure to move in a vertical direction opposite to the direction when the roller brush rotates clockwise;

[0087] When the roller brush rotates counterclockwise, the interference structure is located above the position where the interference structure is located when the roller brush rotates clockwise.

[0088] When the liquid distributor reciprocates in a straight line along the vertical direction, the motion trajectory is relatively simple, and the adjustment method of the interference amount between the interference structure and the roller brush can be further simplified.

[0089] The second aspect of the present disclosure provides a cleaning device, the cleaning device comprising a body and a floor brush structure as described in the first aspect; the body is connected to the floor brush structure; the body comprises a first box and a second box, the first box is configured to store the cleaning medium; the second box is configured to collect dirt. .

[0090] The floor brush structure is one of the components of the cleaning device, and the cleaning device also has the above-mentioned beneficial effects, which will not be described again here. BRIEF DESCRIPTION OF THE DRAWINGS

[0122] In the embodiments of the present disclosure, the cleaning device is described by taking a floor scrubber as an example. It is understandable that the cleaning device is not limited to a floor scrubber. For example, the cleaning device may also be a sweeping robot.

[0123] like Figure 1As shown, the floor scrubber generally includes a floor brush structure 100 and a body 200, the body 200 is connected to the floor brush structure 100, and the floor brush structure 100 has a certain supporting effect on the body 200, so that the body 200 can stand upright on the floor brush structure 100 without external force. The roller brush 110 is one of the components of the floor brush structure 100.

[0124] The body 200 includes a first box 210 for storing cleaning media and a second box 220 for collecting dirt. The cleaning media in the first box 210 flows to the floor brush structure 100 through a pipeline and is then applied to the roller brush 110. The wetted roller brush 110 rubs the surface to be cleaned (such as the ground) by rotation, thereby achieving the cleaning purpose. The amount of liquid falling to the ground increases due to various reasons such as uneven distribution of the cleaning media applied to the roller brush 110 and the small amount of cleaning media carried by the roller brush 110. The limited suction force cannot completely suck the dirt into the second box 220, so that there are more water stains on the ground after cleaning, causing the ground to be slippery. Moreover, during the cleaning process, the roller brush 110 of the floor scrubber mostly rotates unidirectionally in a counterclockwise direction, and the friction between the roller brush 110 and the ground is small. Although this state can clean most of the dust, there are still stubborn stains remaining on the ground, and the cleaning effect is poor, which reduces the user experience.

[0125] In order to further improve the above-mentioned problems of residual water stains and poor cleaning effect, the embodiments of the present disclosure provide a floor brush structure 100 and a cleaning device having the floor brush structure.

[0126] The following will be combined Figures 2 to 20 The floor brush structure 100 and the cleaning device are further described respectively.

[0127] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the floor brush structure 100 includes: a roller brush 110, a liquid distributor 130 ( Figure 7 ) and the interference structure 120, wherein the liquid distributor 130 is provided with a first liquid outlet 1321 (see Fig.13 and Fig.14 ), the dispenser 130 is configured to apply a cleaning medium to the roller brush 110.

[0128] The interference structure 120 includes: a first interference member 121 and a second interference member 122; the first interference member 121 is located on the upper side of the first liquid outlet 1321, and the second interference member 122 is located on the lower side of the first liquid outlet 1321; when the roller brush 110 rotates counterclockwise (such as Figure 6When the direction is indicated by the middle arrow, the first interference member 121 and the second interference member 122 are both in contact with the roller brush 110, and the interference amount between the first interference member 121 and the roller brush 110 is smaller than the interference amount between the second interference member 122 and the roller brush 110; under the action of external force, the liquid distributor 130 can move relative to the roller brush 110 to change the interference amount between the interference structure 120 and the roller brush 110.

[0129] In the embodiment of the present disclosure, for the convenience of description, the "counterclockwise rotation" of the roller brush 110 is referred to as forward rotation, and the "clockwise rotation" is referred to as reverse rotation.

[0130] When the roller brush 110 rotates forward, the roller brush 110 provides assistance to the user to push the cleaning device forward (away from the user's location).

[0131] The liquid distributor 130 may be in communication with the first housing 210 through a pipeline to distribute the cleaning medium from the first housing 210 so that the cleaning medium is sprayed toward the rolling brush 110 through the first liquid outlet 1321 .

[0132] Exemplarily, the cleaning medium may be water, or a mixed liquid of water and a detergent, wherein the detergent generally refers to a surfactant having a cleaning effect.

[0133] like Figure 7 and Fig. 9 As shown, the cleaning medium is sprayed toward the roller brush 110 from between the first interference member 121 and the second interference member 122 after being separated by the liquid separator 130. When the roller brush 110 rotates forward, the cleaning medium passes through the first interference member 121 before cleaning the ground, and then passes through the second interference member 122 after cleaning the ground.

[0134] like Figure 7 As shown, the first interference member 121 is located above the second interference member 122, and the first interference member 121 and the second interference member 122 are in contact with different positions of the roller brush 110 in the circumferential direction. Figure 7 As shown, the roller brush 110 includes a roller shaft 111 and a roller cloth 113 covering the outer circumference of the roller shaft 111. The roller brush 110 rubs the surface to be cleaned through the roller cloth 113. The roller cloth 113 has bristles 112.

[0135] In an alternative embodiment, if Figure 7 As shown, when the roller brush 110 rotates forward, the first interference member 121 and the second interference member 122 are both in contact with the roller cloth 113; and the distance x1 between the second interference member 122 and the roller 111 is 1 mm to 2.5 mm.

[0136] Exemplarily, x1 may be any value between 1 mm and 2.5 mm, for example, x1 may be 1 mm, 1.2 mm, 1.5 mm, 2 mm or 2.5 mm.

[0137] It should be understood that the interference between the second interference member 122 and the roller 111 will directly affect the scraping effect. When the distance between the second interference member 122 and the roller 111 is too short, the scraping effect will be greatly reduced. When the distance between the second interference member 122 and the roller 111 is too long, the second interference member 122 may interfere with the roller 111 or directly damage the bristles. Therefore, the distance in the present application can ensure the dirt scraping effect and also avoid the situation where the second interference member 122 affects the life of the bristles.

[0138] When the roller brush 110 rotates forward, the distance x2 between the first interference member 121 and the circumference of the roller 111 is the sum of the distance x1 between the second interference member 122 and the circumference of the roller 111 and the constant D. That is, x2=x1+D, wherein the constant D is greater than zero.

[0139] Exemplarily, D may be any value between 0.5 mm and 2.5 mm. For example, D may be 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, or 2.5 mm.

[0140] It can be expressed as follows: when the roller brush 110 rotates forward, x1=(1-2.5) mm, x2=x1+(0.5-2.5) mm.

[0141] On the basis that both the first interference member 121 and the second interference member 122 are in contact with the rolling cloth 113 , the interference amount between the second interference member 122 and the rolling brush 110 can be indirectly determined by using the distance between the second interference member 122 and the roller 111 .

[0142] When the distance between the second interference member 122 and the roller 111 is 1 mm to 2.5 mm, it indicates that the interference between the second interference member 122 and the roller brush 110 is relatively large, and the second interference member 122 can more effectively separate dirt on the roller brush 110 .

[0143] It has been mentioned above that the first interference member 121 and the second interference member 122 are in contact with the roller brush 110 during forward rotation. During forward rotation, the interference between the second interference member 122 and the roller brush 110 is greater, while the first interference member 121 is also in contact with the roller brush 110. At this time, the first interference member 121 has a water uniforming effect.

[0144] In other words, if the interference between the first interference member 121 and the roller brush 110 is too large, it will become a scraping function, and water distribution will not be possible. Therefore, when the interference between the second interference member 122 and the roller brush 110 is large, the value of the interference between the first interference member 121 and the roller brush 110 is very important. The above formula provided in the present application can directly obtain the interference between the first interference member 121 and the roller brush 110 according to the interference between the second interference member 122 and the roller brush 110, so that the second interference member 122 and the first interference member 121 can achieve optimal usage.

[0145] The interference amount can also be understood as the amount of compression of the roller brush 110 under external force. The first interference member 121 and the second interference member 122 both exert a certain extrusion force on the roller brush 110 through interference with the roller brush 110. Among them, the size of the interference amount is roughly proportional to the extrusion force on the roller brush 110. The larger the interference amount, the greater the extrusion force on the roller brush 110. Therefore, when the roller brush 110 rotates forward, the extrusion force of the first interference member 121 on the roller brush 110 is less than the extrusion force of the second interference member 122 on the roller brush 110.

[0146] like Figure 4 and Figure 7 As shown, when the roller brush 110 rotates forward, the liquid droplets are easily thrown out due to the centrifugal force generated by the rotation of the roller brush 110. The first interference member 121 can block the cleaning medium from above, block the thrown liquid droplets, reduce the cleaning medium from falling to the ground, thereby reducing the generation of water stains and improving the cleaning effect.

[0147] After the liquid dispenser 130 applies the cleaning medium, the cleaning medium squeezed out by the first interference member 121 is blocked by the second interference member 122 and will not easily drip onto the ground to form water stains.

[0148] Since both the first interference member 121 and the second interference member 122 are in contact with the roller brush 110, the cleaning medium can be temporarily stored between the first interference member 121 and the second interference member 122, and this part of the cleaning medium still remains in contact with the roller brush 110. Under the action of gravity or the inertial force generated by the rotation of the roller brush 110, the cleaning medium temporarily stored between the first interference member 121 and the second interference member 122 will flow to the area with less cleaning medium content in the roller brush 110 and be reabsorbed by the roller brush 110. Therefore, the cooperation of the first interference member 121 and the second interference member 122 can also improve the phenomenon of water stain residue and improve the cleaning effect.

[0149] like Figure 6 and Figure 7As shown, since the first interference member 121 is located behind the liquid distributor 130 when the roller brush 110 rotates forward, the possibility of the cleaning medium being squeezed off by the first interference member 121 can be reduced by using the small interference amount of the first interference member 121 on the roller brush 110. At the same time, the cleaning medium will be gathered to a certain height on the upstream side of the first interference member 121 (referring to the side of the first interference member 121 facing the second interference member 122), so that the height of the cleaning medium on the upstream side of the first interference member 121 is greater than the height of the cleaning medium on the downstream side of the first interference member 121 (referring to the opposite side of the upstream side), so that under the action of the liquid height difference and the rotation of the roller brush 110, the cleaning medium is more likely to flow to the downstream side with a lower cleaning medium content. Therefore, the first interference member 121 has the function of "smoothing" the cleaning medium, and the function of liquid homogenization.

[0150] The liquid homogenizing effect of the first interference member 121 is also reflected in that the cleaning medium will flow along the axial direction of the roller brush 110 of the first interference member 121 under the guidance of the first interference member 121 , and will not gather in a small area of ​​the roller brush 110 .

[0151] When the roller brush 110 rotates forward, the larger interference amount of the second interference member 122 on the roller brush 110 can effectively squeeze out the liquid on the roller brush 110 and separate the dirt from the roller brush 110 .

[0152] When the rolling brush 110 is reversed, the first interference member 121 and the second interference member 122 are not separated from the rolling cloth 113 , that is, the first interference member 121 and the second interference member 122 are both in contact with the rolling cloth 113 .

[0153] like Fig. 9 As shown, when the roller brush 110 is reversed, the distance x1 between the second interference member 122 and the circumference of the roller 111 is the sum of the distance x2 between the first interference member 121 and the circumference of the roller 111 and the constant D. That is, x1=x2+D. Wherein, the constant D is greater than zero.

[0154] Exemplarily, D may be any value between 0.5 mm and 2.5 mm. For example, D may be 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm or 2.5 mm.

[0155] Exemplarily, x2 may be any value between 1 mm and 2.5 mm. For example, x2 may be 1 mm, 1.2 mm, 1.5 mm, 2 mm or 2.5 mm.

[0156] It can be expressed as follows: when the roller brush 110 rotates forward, x2=(1-2.5) mm, x1=x2+(0.5-2.5) mm.

[0157] The above scheme can also refer to the above description, and the interference between the first interference member 121 and the roller 111 can also be indirectly determined by using the distance between the first interference member 121 and the roller 111, and both can satisfy the user experience. The first interference member 121 and the second interference member 122 are both approximately equal to the length of the roller brush 110 along the axial direction of the roller brush 110. So that when the roller brush 110 rotates, the first interference member 121 and the second interference member 122 interfere with the entire surface of the roller brush 110.

[0158] The first interference member 121 may be a rigid component or a flexible component.

[0159] The second interference member 122 may be a rigid component or a flexible component.

[0160] When the first interference member 121 and the second interference member 122 are flexible components, they can generate elastic deformation when in contact with the roller brush 110. The flexible components have less wear on the roller brush 110, which is beneficial to increase the service life of the roller brush 110.

[0161] The rigid component is not easily deformed, and the rigid component can squeeze out more dirt on the roller brush 110 .

[0162] When the liquid distributor 130 moves, it can drive the interference structure 120 to move, so that different interference parts and the roller brush 110 have different interference amounts, and the same interference part and the roller brush 110 have different interference amounts.

[0163] In addition, the liquid distributor 130 can be used to drive the movement of the interference structure 120, so that the first interference member 121 and the second interference member 122 maintain a tendency to approach the roller brush 110, thereby ensuring that the interference fit between the interference structure 120 and the roller brush 110 meets the expected requirements, thereby improving the problem of the decrease in the interference fit between the interference structure 120 and the roller brush 110 due to wear and tear of the roller brush 110.

[0164] To sum up, the technical solution of the embodiment of the present disclosure can achieve both better water uniformity and better dirt scraping effect, and at the same time it can ensure that after the roller brush has been used for a long time and the diameter of the roller brush has changed, it can still achieve almost the same effect as before the change.

[0165] like Figure 7 As shown, in the embodiment illustrated in the present disclosure, the first interference member 121 and the second interference member 122 are respectively connected to the liquid distributor 130 and are respectively located at the upper and lower sides of the first liquid outlet 1321 .

[0166] In this way, the first interference member 121 and the second interference member 122 move simultaneously with the liquid dispenser 130 , and there is no need to drive the first interference member 121 and the second interference member 122 separately, which can reduce the structural complexity of the floor brush structure 100 and the complexity of operating the interference structure 120 .

[0167] Moreover, the positions of the liquid dispenser 130 and the interference structure 120 may be different, such as Figure 7 As shown, the interference structure 120 is located further forward (i.e., closer to the roller brush 110), while the liquid distributor 130 is located further back. After the interference structure 120 and the liquid distributor 130 are connected, in addition to directly acting on the interference structure 120 to make the interference structure 120 and the liquid distributor 130 move together, the external force can also be applied to the liquid distributor 130 to achieve the movement of the liquid distributor 130 and the movement of the interference structure 120. The first interference member 121 and the second interference member 122 are connected to the liquid distributor 130 respectively, so that the method of adjusting the interference amount between the interference structure 120 and the roller brush 110 can be more flexible.

[0168] like Figures 1 to 3 As shown, in the embodiment illustrated in the present disclosure, the number of the roller brush 110 is one, and the roller brush 110 matches one interference structure 120 and one liquid dispenser 130 .

[0169] In the embodiment not shown in the figure of the present disclosure, the number of roller brushes is two, and the two roller brushes are arranged side by side along the travel direction of the cleaning device. Each roller brush can be matched with an interference structure and a liquid distributor, or only one of the roller brushes can be matched with the interference structure 120 and the liquid distributor 130 described in the embodiment of the present disclosure. In addition, the number of roller brushes can be more than two, and the number of interference structures and liquid distributors can correspond to the number of roller brushes one by one, but it is not limited thereto.

[0170] like Figure 4 and Figure 5 As shown, according to some optional embodiments, the roller brush 110 is covered with a plurality of bristles 112 , and when the roller brush 110 is reversed, the first interference member 121 turns up the bristles 112 .

[0171] When the roller brush 110 is reversed, the roller brush 110 can provide assistance for the user to pull the cleaning device backward (toward the direction close to the user's position). Figure 4 and Figure 5 As shown, the rolling cloth 113 includes bristles 112, and the bristles 112 can be formed on the base layer of the rolling cloth 113 by planting. When the bristles 112 are made, the bristles 112 and the surface of the roller 111 can have a certain angle, such as Figure 4 As shown, the roller brush 110 is rotating in the direction of the bristles 112, and the bristles 112 are more easily flattened. At this time, the bristles 112 are in a prostrate state. The thickness of the roller cloth 113 generally refers to the thickness extending along the radial direction of the roller brush 110 when the bristles 112 are in a prostrate state.

[0172] like Figure 5As shown, the roller brush 110 is reversed to the direction opposite to the bristles 112, and the bristles 112 are more easily turned up and in an upright state. Compared with the reverse rotation of the roller brush 110, when the roller brush 110 rotates forward, the interference between the roller brush 110 and the ground is smaller, the positive pressure applied by the bristles 112 to the ground and the stains is reduced, and the friction force of the bristles 112 when scraping the stains is smaller.

[0173] When the roller brush 110 is reversed, Figure 5 As shown, the bristles 112 first contact the first interference member 121, and the prostrated bristles 112 ( Figure 5 The bristles 112 (a)) are turned up under the blocking effect of the first interference member 121 to form upright bristles 112 (b). Since the bristles 112 have a certain "rigidity", the turned up bristles 112 will still maintain a good upright state 112 (c) when the roller brush 110 continues to reverse to the ground 300, and the "rigidity" of the bristles 112 can apply greater positive pressure to the ground and the stains.

[0174] Therefore, compared with the forward rotation of the roller brush 110, the reverse rotation of the roller brush 110 can achieve a better cleaning effect. In addition, when the roller brush 110 is reversed, since the bristles 112 are turned up, the amount of liquid stored in the bristles 112 is greater than when it is lying down, the liquid recovery rate on the roller brush 110 is reduced, and more liquid will flow to the ground. This part of the liquid flowing to the ground can soften the stains, making the stains easier to remove, and can assist in cleaning stubborn stains, further improving the cleaning effect.

[0175] It is understandable that when the roller brush 110 rotates forward again, it will not only suck the liquid remaining during the reverse rotation, but also restore the fluff to the lying state. As the roller brush 110 rotates forward and reverse alternately, the bristles 112 will also switch between the erected and lying states. Figure 4 and Figure 5 As shown, the first interference member 121 extends upwardly and obliquely toward the axis of the roller brush 110. When the roller brush 110 is reversed, the first interference member 121 extending upwardly and obliquely toward the axis of the roller brush 110 can be opposite to the original oblique direction of the bristles 112, thereby more conveniently turning up the bristles 112.

[0176] When the roller brush rotates forward, the first interference member 121 extending obliquely upward will not affect the rotation of the roller brush 110, and can also make the liquid on the roller brush 110 more evenly distributed by smoothing.

[0177] Alternatively, if Figure 4 and Figure 5As shown, the second interference member 122 extends obliquely downward toward the axis of the roller brush 110. When the roller brush 110 rotates forward, the second interference member 122 extending obliquely downward can guide the dirt squeezed out by it, so that the dirt flows along the second interference member 122 to the roller brush 110 and is reabsorbed by the roller brush 110, reducing the liquid dripping to the ground.

[0178] like Figure 5 , Figure 8 and Fig. 9 As shown, when the roller brush 110 is reversed, the interference between the first interference member 121 and the roller brush 110 is greater than the interference between the second interference member 122 and the roller brush 110 .

[0179] When the roller brush 110 is reversed, the interference between the first interference member 121 and the roller brush 110 is relatively large, so the bristles 112 can be flipped up to a higher upright state, ensuring that the bristles 112 still maintain good "rigidity" when reaching the ground.

[0180] Moreover, the first interference member 121 can be used to squeeze out dirt on the roller brush 110, thereby separating sewage and solid waste. The second interference member 122 having a smaller interference amount with the roller brush 110 can not only reduce the obstruction of dirt scraped off by the first interference member 121, but also assist in turning over the bristles 112. The larger interference amount between the first interference member 121 and the roller brush 110 can separate dirt more cleanly.

[0181] When the liquid distributor 130 is configured to rotate, when the roller brush 110 rotates forward, the liquid distributor 130 drives the interference structure 120 to rotate in a direction opposite to the direction when the roller brush 110 rotates reversely. When the liquid distributor is configured to rotate, the interference structure 120 rotates in opposite directions when the roller brush 110 rotates forward and reversely. This swinging rotation method can adjust the interference amount between the interference structure 120 and the roller brush 110 at a smaller rotation angle, reducing the occupation of the internal space of the floor brush structure 100 and the interference with other components in the floor brush structure 100 due to large-angle rotation.

[0182] For example: Figure 6 As shown, the liquid distributor 130 is configured to rotate. When the liquid distributor 130 rotates clockwise within a certain angle range, the interference between the first interference member 121 and the roller brush 110 can be smaller than the interference between the second interference member 122 and the roller brush 110 .

[0183] During the rotation process, the interference between the first interference member 121 and the roller brush 110 decreases as the rotation angle of the liquid distributor 130 increases, and the interference between the second interference member 122 and the roller brush 110 increases as the rotation angle of the liquid distributor 130 increases.

[0184] like Figure 8As shown, when the liquid distributor 130 rotates counterclockwise within a certain angle range, the interference between the first interference member 121 and the roller brush 110 can be greater than the interference between the second interference member 122 and the roller brush 110. During this rotation process, the interference between the first interference member 121 and the roller brush 110 increases as the rotation angle of the liquid distributor 130 increases, and the interference between the second interference member 122 and the roller brush 110 decreases as the rotation angle of the liquid distributor 130 increases.

[0185] In some optional embodiments, the interference between the same interference member and the roller brush 110 can be changed by controlling the rotation angle of the liquid distributor 130. The rotation direction of the liquid distributor 130 can also be controlled to achieve different interferences between different interference members and the roller brush 110.

[0186] In addition to rotation, the movement of the liquid distributor 130 relative to the roller brush 110 may also be linear motion, or a combination of linear motion and rotation, but is not limited thereto.

[0187] Fig.21 An example in which the liquid dispenser 130 drives the interference structure 120 to move linearly is exemplarily shown.

[0188] like Fig.21 As shown, when the roller brush 110 rotates counterclockwise, the liquid distributor 130 drives the interference structure 120 to move in the vertical direction in the opposite direction to the moving direction when the roller brush 110 rotates clockwise; and when the roller brush 110 rotates counterclockwise, the position of the interference structure 120 is located at the position where it is located when the roller brush 110 rotates clockwise ( Fig.21 The dashed line indicates the top of the dispenser 130 and the interference structure 120).

[0189] When the liquid distributor 130 and the interference structure 120 reciprocate in a straight line along the vertical direction, the movement trajectory is relatively simple, and the adjustment method of the interference amount between the interference structure 120 and the roller brush 110 can be further simplified.

[0190] For example, Fig.12 and Fig.13 As shown, the interference structure 120 and the liquid distributor 130 are split structures. The interference structure 120 has a slot on the side facing away from the roller brush 110. The liquid distributor 130 is inserted into the slot. The connection between the liquid distributor 130 and the interference structure 120 is a detachable connection.

[0191] When the interference structure 120 and the liquid dispenser 130 are split structures, the interference structure 120 and the liquid dispenser 130 can be designed separately, and the structures of the interference structure 120 and the liquid dispenser 130 can be more flexible and easier to manufacture.

[0192] In addition to the clamping connection, the liquid distributor 130 and the interference structure 120 can also be connected by fasteners such as screws and bolts, or by other connection methods such as bonding. Moreover, the connection between the liquid distributor 130 and the interference structure 120 can be non-detachable, that is, fixed, in addition to the detachable connection.

[0193] In the disclosed embodiment, the detachable mode may refer to: the two originally connected parts will not be damaged after being disassembled, and can be restored after being assembled, and can be disassembled and assembled repeatedly. The fixed mode refers to: at least one of the two originally connected parts will be damaged after being disassembled, and cannot be assembled and restored again.

[0194] In some optional embodiments, the interference structure 120 and the liquid distributor 130 are integral structures. For example, the interference structure 120 and the liquid distributor 130 may be integrally formed by injection molding or machining.

[0195] When the interference structure 120 and the liquid dispenser 130 are integral structures, at least the assembly steps of the interference structure 120 and the liquid dispenser 130 can be saved, and the assembly and maintenance of the brush structure 100 are convenient.

[0196] like Figure 7 and Fig. 9 As shown, the first interference member 121 and the second interference member 122 are integral structures and connected to the liquid dispenser 130. When the interference structure 120 is an integral structure, at least the assembly steps of the first interference member 121 and the second interference member 122 can be saved, which facilitates the assembly of the interference structure 120 and the liquid dispenser 130.

[0197] For example, Figures 11 to 13 As shown, the interference structure 120 and the liquid distributor 130 are split structures, and the first interference member 121 and the second interference member 122 are integral structures. In addition to the first interference member 121 and the second interference member 122, the interference structure 120 also includes a connecting portion 123 located between the first interference member 121 and the second interference member 122, the first interference member 121 and the second interference member 122 are spaced apart, one side of the connecting portion 123 faces the roller brush 110, and the other side of the connecting portion 123 facing away from the roller brush 110 is connected to the liquid distributor 130, and the liquid distributor 130 is located between the first interference member 121 and the second interference member 122.

[0198] The connecting portion 123 has a second liquid outlet hole 124 communicated with the first liquid outlet hole 1321 , and the cleaning medium in the liquid distributor 130 is finally applied to the roller brush 110 through the second liquid outlet hole 124 .

[0199] When the first interference member 121 and the second interference member 122 are an integral structure, the connection portion 123 is a part of the interference structure 120, and the connection portion 123 can be used as a carrier for installing the liquid distributor and as a component of the fluid channel for the liquid distributor to apply the cleaning medium. The cleaning medium flowing out of the liquid distributor 130 through the first liquid outlet 1321 is applied to the roller brush 110 through the second liquid outlet 124 of the connection portion 123.

[0200] exist Fig.13 In the illustrated embodiment, the liquid distributor 130 includes a liquid inlet member 131 having a liquid inlet joint 1311 and a liquid distributor 132 having a plurality of first liquid outlet holes 1321. The liquid distributor 132 is located between the liquid inlet member 131 and the connecting portion 123.

[0201] The liquid inlet member 131 and the liquid separator 132 together form a first chamber, and the liquid separator 132 and the interference structure 120 together form a second chamber. The cleaning medium in the first box 210 in the body 200 can enter the first chamber through the pipeline via the liquid inlet connector 1311.

[0202] The resistance of the cleaning medium entering the first chamber is less than the resistance of the cleaning medium flowing out of the first liquid outlet 1321, and then after the cleaning medium fills the first chamber, the cleaning medium will flow into the second chamber from the multiple first liquid outlets 1321 at the same time. Similarly, after the second chamber is filled with the cleaning medium, it will flow out from the multiple second liquid outlets 124 at the same time. The axis of the second liquid outlet 124 is roughly parallel to the axis of the first liquid outlet 1321, and the multiple first liquid outlets 1321 and the multiple second liquid outlets 124 are all arranged along the axial direction of the roller brush 110. When the roller brush 110 rotates, the multiple second liquid outlets 124 can make the cleaning medium more evenly distributed on the entire surface of the roller brush 110.

[0203] Generally, a liquid pump is connected between the first box body 210 and the liquid inlet connector 1311 to increase the pressure of the cleaning medium entering the liquid distributor 130 to achieve liquid spraying.

[0204] exist Fig.14 In the illustrated embodiment, the first interference member 121 and the second interference member 122 are split structures. The first interference member 121 and the second interference member 122 are spaced apart, and the liquid dispenser 130 is located between the first interference member 121 and the second interference member 122. The first interference member 121 is disposed at the upper end of the liquid dispenser 130 and connected to the upper end surface of the liquid dispenser 130, and the second interference member 122 is disposed at the lower end of the liquid dispenser 130 and connected to the lower bottom surface of the liquid dispenser 130. The first interference member 121 and the second interference member 122 can be connected to the liquid dispenser 130 by fasteners such as screws and bolts, adhesive connection, and snap connection. The first interference member 121 and the second interference member 122 can be connected to the liquid dispenser 130 in a fixed manner or in a detachable manner.

[0205] When the first interference member 121 and the second interference member 122 are split structures, the interval between the first interference member 121 and the second interference member 122 can reserve installation space for the liquid distributor 130, so as to directly apply the cleaning medium to the roller brush 110 through the first liquid outlet 1321; the first interference member 121 and the second interference member 122 are respectively connected to the upper and lower end surfaces of the liquid distributor 130, so that the distance between the first interference member 121 and the second interference member 122 is larger. This larger distance can reserve more space for the first liquid outlet, and also effectively increase the coverage area of ​​the cleaning medium applied to the roller brush 110 through the first liquid outlet 1321, thereby making the distribution of the cleaning medium on the roller brush 110 more uniform.

[0206] Fig.14 The exemplary interference structure 120 is composed of two independent scraping bars (ie, a first interference member 121 and a second interference member 122 ), the liquid distributor 130 is located in the interval between the two scraping bars, and the cleaning medium can be directly sprayed toward the roller brush 110 through the first liquid outlet 1321 .

[0207] The driving force for the interference structure 120 and the liquid distributor 130 to move can come from the rotation of the roller brush 110. Using the rotation of the roller brush 110 to drive the interference structure 120 to rotate not only improves the utilization rate of the roller brush 110, but also eliminates the need to set up an additional driving component to drive the interference structure 120 to rotate, which is conducive to cost saving. For example, the interference structure 120 moves with the rotation of the roller brush 110.

[0208] Using the rotation of the roller brush 110 to drive the interference structure 120 to rotate not only improves the utilization rate of the roller brush 110 , but also eliminates the need for an additional driving component to drive the interference structure 120 to rotate. In other words, the interference adjustment can be adaptively adjusted according to the rotation of the roller brush 110 .

[0209] When the roller brush 110 rotates forward, Figure 7 As shown, because the roller brush 110 is in contact with the interference structure 120, the roller brush 110 will drive the interference structure 120 and the liquid distributor 130 to rotate clockwise, thereby achieving an interference amount between the second interference member 122 and the roller brush 110 greater than the interference amount between the first interference member 121 and the roller brush 110; similarly, when the roller brush 110 is reversed, as shown in FIG. Fig. 9 As shown, the roller brush 110 drives the interference structure 120 and the liquid distributor 130 to rotate counterclockwise, thereby achieving that the interference between the second interference member 122 and the roller brush 110 is smaller than the interference between the first interference member 121 and the roller brush 110 .

[0210] In addition, the driving force for the movement of the interference structure 120 and the liquid distributor 130 may not come from the rotation of the roller brush 110. The floor brush structure 100 also includes a first driving component, and the first interference member 121 and the second interference member 122 move under the driving action of the first driving component. The first driving component can provide driving force for the movement of the liquid distributor 130 and the interference structure 120.

[0211] The first driving component, which is the source of the driving force for driving the interference structure, can control the rotation of the roller brush 110 and the movement of the interference structure 120 separately, which is conducive to the refined design of the movement trajectory of the interference structure 120 and helps to realize the intelligent control of the movement of the interference structure 120.

[0212] Optionally, the first driving assembly includes a first driving source and a first transmission assembly, the first driving source generates driving force, and the first transmission assembly can transmit the driving force to the interference structure 120 and the liquid dispenser 130. The driving force of the first driving assembly to drive the interference structure 120 can be a linear driving force or a rotational driving force.

[0213] Combination Figure 3 As shown, the dispenser 130 and the interference structure 120 can rotate around the rotating shaft 170. If the first driving component provides a rotational driving force, when the roller brush 110 rotates forward, the first driving component can drive the interference structure 120 and the dispenser 130 to rotate counterclockwise; when the roller brush 110 rotates reversely, the first driving component can drive the interference structure 120 and the dispenser 130 to rotate clockwise.

[0214] If the first drive assembly provides a linear drive force, such as Fig.15 As shown, the linear driving force can be substantially parallel to the horizontal direction. When the roller brush 110 rotates forward, the first driving component 190 pushes ( Fig.15 The middle arrow x) liquid distributor 130 and the interference structure 120, so that the interference between the first interference member 121 and the roller brush 110 is smaller than the interference between the second interference member 122 and the roller brush 110; when the roller brush 110 is reversed, the first driving assembly 190 pulls ( Fig.15 The middle arrow y) indicates the liquid distributor 130 and the interference structure 120, so that the interference between the first interference member 121 and the roller brush 110 is greater than the interference between the second interference member 122 and the roller brush 110.

[0215] The first driving source includes but is not limited to a motor, an electromagnet, etc. The first transmission component includes but is not limited to a gear transmission, a rack transmission, a conveyor belt transmission or a cam transmission, etc.

[0216] In some optional embodiments of the present disclosure, Figure 6 and Fig.18As shown, the floor brush structure 100 further includes a shell 140 and an air duct 104 . The interference structure 120 and the liquid distributor 130 are both located above the air duct 104 and connected to the shell 140 of the floor brush structure 100 .

[0217] The interference structure 120 and the liquid distributor 130 are located above the air duct 104, so that the dirt scraped by the interference structure 120 can be promptly sucked away by the air duct 104 when it falls due to gravity, thereby ensuring the cleaning effect. The interference structure 120 and the liquid distributor 130 can be movably mounted on the housing 140, and the housing 140 can form the entire or partial structure of the air duct 104. The roller brush 110 is rotatably connected to the housing 140.

[0218] According to some optional embodiments, Fig.16 As shown, the floor brush structure 100 further includes: a roller brush cover assembly located above the roller brush 110, a liquid distributor 130 and an interference structure 120 connected to the roller brush cover assembly, and the interference structure 120 can be displaced under the action of external force to change the interference amount.

[0219] The existing roller brush cover assembly in the floor brush structure 100 is used to provide a mounting carrier for the interference structure 120 and the liquid distributor 130. No additional carrier is required to mount the interference structure 120 and the liquid distributor 130, which is beneficial to saving costs and reducing occupied space.

[0220] When the roller brush 110 rotates, centrifugal force is generated, and liquid, particles, etc. attached to the roller brush 110 are thrown out along the tangential direction of the roller brush 110 under the action of the centrifugal force, and the roller brush cover assembly is configured to block the liquid or particles thrown out by the roller brush 110.

[0221] It is understandable that the interference structure 120 and the liquid distributor 130 can also be connected to the roller brush cover assembly and the housing 140 at the same time. Fig.17 and Fig.18 As shown, the roller brush cover assembly includes a movable first roller brush cover 160, the interference structure 120 and the rotating shaft 170 of the liquid dispenser 130 can be fixed to the shell 140, and the connection between the interference structure 120 and the first roller brush cover 160 is used to achieve movement.

[0222] The first roller brush cover 160 of the roller brush cover assembly can switch between a first position and a second position relative to the roller brush 110. The first roller brush cover 160 is connected to the interference structure 120 and the liquid distributor 130 to drive the liquid distributor 130 to move under the action of the movement of the first roller brush cover 160, thereby adjusting the interference amount between the first interference member 121, the second interference member 122 and the roller brush 110 respectively.

[0223] by Fig.17 and Fig.18 When the first roller brush cover 160 is in the first position, Fig.18As shown, when the roller brush 110 rotates forward, the first roller brush cover 160 is separated from the roller brush 110, and a gap H is formed between the two.

[0224] The first roller brush cover 160 drives the liquid distributor 130 and the interference structure 120 to rotate clockwise, thereby adjusting the interference between the first interference member 121 and the roller brush 110 to be smaller than the interference between the second interference member 122 and the roller brush 110; when the roller brush 110 is reversed, Fig.17 As shown, when the first roller brush cover 160 is in the second position, the first roller brush cover 160 drives the dispenser 130 and the interference structure 120 to rotate counterclockwise, thereby adjusting the interference amount between the first interference member 121 and the roller brush to be greater than the interference amount between the second interference member 122 and the roller brush 110.

[0225] Since the first roller brush cover 160 is used to block the liquid or dirt thrown out when the roller brush 110 rotates, when the first roller brush cover 160 contacts the roller brush 110 , the rotating roller brush 110 can scrub the dirt remaining on the inner wall of the first roller brush cover 160 .

[0226] When the interference structure 120 is connected to the first roller brush cover 160, the movement of the first roller brush cover 160 can be used to drive the interference structure 120 and the liquid dispenser 130 to move, without the need to set up additional driving components for the interference structure 120 and the liquid dispenser 130, thus achieving multiple goals at one stroke.

[0227] Fig.17 and Fig.18 In the embodiment shown, the liquid dispenser 130 and the interference structure 120 are connected to both the roller brush cover assembly and the housing 140. The first roller brush cover 160 is used to drive the liquid dispenser 130 and the interference structure 120 to move, and the housing 140 is used to support the rotating shaft 170 of the liquid dispenser 130 and the interference structure 120, so that the stability of the movement of the liquid dispenser 130 and the interference structure 120 and the reliability of installation can be ensured.

[0228] The floor brush structure 100 also includes: a second driving component, which can provide driving force for the movement of the first roller brush cover 160. The second driving component can drive the first roller brush cover 160 to move, thereby driving the interference structure 120 and the liquid distributor 130 to move.

[0229] The second driving assembly is used to drive the first roller brush cover 160 to switch between the first position and the second position, and to drive the interference structure 120 and the liquid dispenser 30 to move through the first roller brush cover 160, thereby realizing two purposes of one driving assembly.

[0230] Fig.17It is exemplarily shown that the second driving component includes a spring 101, under the action of the elastic force of the spring 101, the first roller brush cover 160 can be driven to move toward the roller brush so as to contact the roller brush 110 and reach the second position; conversely, if an external force is used to overcome the elastic force of the spring 101, the first roller brush cover 160 can move in a direction away from the roller brush 110.

[0231] The first roller brush cover 160 can be kept in the first position by setting a limiting structure, and the limiting structure on the first roller brush cover 160 can be manually or electrically released so that the first roller brush cover 160 automatically returns to the second position under the action of the spring 101.

[0232] In addition to the spring 101, the second drive component can also be a torsion spring, a spring, a tension spring, etc. In addition, the second drive component can also be an electric drive component, for example: the second drive component includes a second drive source and a second transmission component, the second drive source generates a driving force, and the second transmission component transmits the driving force generated by the second drive source to the first roller brush cover 160 to drive the first roller brush cover 160, the interference structure 120 and the liquid distributor 130 to move.

[0233] The specific structure of the second driving source can refer to the first driving source, and the second transmission assembly can refer to the first transmission assembly, which will not be described again. When the second driving assembly is an electric driving assembly, intelligent control of the first roller brush cover 160, the interference structure 120 and the liquid distributor 130 can be achieved.

[0234] According to some optional embodiments, Fig.16 As shown, the liquid distributor 130 is rotatably disposed on the inner side of the first roller brush cover 160 and enables the first interference member 121 and the second interference member 122 to contact the roller brush 110. When the roller brush 110 rotates, the liquid distributor 130 can be driven to rotate to adjust the interference between the first interference member 121 and the second interference member 122 and the roller brush 110.

[0235] In addition to using the second driving component to realize the movement of the first roller brush cover 160, the interference structure 120 and the liquid distributor 130, the rotating roller brush 110 can also be used to drive the interference structure 120 and the liquid distributor 130 to rotate, and the interference structure 120 and the liquid distributor 130 can then drive the first roller brush cover 160 to move.

[0236] When the roller brush 110 rotates forward, the rotating roller brush 110 drives the interference structure 120 and the liquid distributor 130 to rotate clockwise by contact with the interference structure 120, and the interference structure 120 further drives the first roller brush cover 160 to move upward to separate from the roller brush 110. Conversely, when the roller brush 110 rotates reversely, the rotating roller brush 110 drives the interference structure 120 and the liquid distributor 130 to rotate counterclockwise by contact with the interference structure 120, and the interference structure 120 further drives the first roller brush cover 160 to move downward to contact with the roller brush 110.

[0237] In some optional embodiments, the movement of the first roller brush cover and the movement of the interference structure may be unrelated, that is, the two move independently.

[0238] like Figures 16 to 19 As shown, the roller brush cover assembly further includes: a second roller brush cover 150 , which is connected to the housing 140 and has a gap with the roller brush 110 , and a first roller brush cover 160 is located in the gap between the second roller brush cover 150 and the roller brush 110 .

[0239] The second roller brush cover 150 is a fixed cover plate, which can be used as a carrier for installing the second driving component, and can also cover the first roller brush cover 160 to protect the first roller brush cover 160.

[0240] like Fig. 20 As shown, according to some optional embodiments, the liquid distributor 130 is disposed below the roller brush cover assembly, and an elastic member 107 is disposed between the roller brush cover assembly and the first interference member 121. When the liquid distributor 130 moves, the elastic member 107 is deformed accordingly. Figure 7 and Fig.10 As shown, there is a certain spacing space 102 between the first interference member 121 and the roller brush cover assembly. During the cleaning process, the dirt thrown out by the roller brush 110 when rotating, and the dirt separated by the roller brush 110 when the roller brush 110 is reversed, which is squeezed by the first interference member 121, may remain in the spacing space 102. Fig. 20 As shown, after the elastic member 107 is arranged between the roller brush cover assembly and the first interference member 121 , the elastic deformation characteristics of the elastic member 107 can be used to block the interval space 102 , thereby eliminating the sanitary dead corner above the first interference member 121 .

[0241] The elastic deformation characteristics of the elastic member 107 can also adapt to the movement of the liquid dispenser 130 and the interference structure 120 , thereby ensuring the smoothness of the movement of the interference structure 120 and the liquid dispenser 130 .

[0242] Fig. 20 The schematic diagram of the partial structure of the floor brush structure 100 when the roller brush 110 is reversed is shown as an example. If the roller brush 110 starts to rotate forward, the liquid distributor 130 rotates in the clockwise direction, and the liquid distributor 130 and the interference structure 120 squeeze the elastic member 107, and the elastic member 107 is compressed. On the contrary, if the roller brush 110 is reversed, the squeezing force of the liquid distributor 130 and the interference structure 120 on the elastic member 107 is reduced, and the elastic member 107 releases elastic deformation. Regardless of whether the roller brush 110 rotates forward or reversely, the interval space 102 between the roller brush cover assembly and the first interference member 121 can be filled with the elastic member 107 without generating a sanitary dead corner.

[0243] According to some optional embodiments, the floor brush structure 100 also includes: a cleaning nozzle (not shown) and a roller brush cover assembly, the cleaning nozzle and the liquid distributor 130 are both arranged below the roller brush cover assembly, and the cleaning nozzle is connected to the liquid distributor 130 to spray the cleaning medium from the liquid distributor 130 between the interference structure 120 and the roller brush cover assembly.

[0244] In this embodiment, the cleaning medium sprayed from the cleaning nozzle is used to clean the dirt that may remain in the spacing space 102 between the roller brush cover assembly and the first interference member 121.

[0245] A pipeline can be constructed separately to connect the nozzle and the first box 210, and the cleaning medium can be directly provided to the nozzle through the first box 210. Alternatively, the nozzle can be connected to the liquid distributor 130, and the cleaning medium sprayed by the nozzle comes from the liquid distributor 130. In this embodiment, the nozzle and the liquid distributor 130 can be an integral structure or a split structure connected to each other.

[0246] In addition, a sewage discharge channel (not shown) may be provided between the air duct 104 and the partition space 102 , and dirt that may remain in the partition space 102 may be transported to the air duct 104 for discharge through the sewage discharge channel.

[0247] like Fig.18 As shown, according to some optional embodiments, the floor brush structure 100 also includes: a first limiting member 105 and a second limiting member 1061 respectively located on the upper and lower sides of the interference structure 120; after the interference structure 120 moves upward by a first displacement, it abuts against the first limiting member 105 to limit the interference structure 120 from continuing to move upward; after the interference structure 120 moves downward by a second displacement, it abuts against the second limiting member 1061 to limit the interference structure 120 from continuing to move downward.

[0248] The first limiter 105 is used to limit the maximum distance that the interference structure 120 can move upward, and the second limiter 1061 is used to limit the maximum distance that the interference structure 120 can move downward. This ensures that the movement range of the interference structure 120 is controllable, thereby ensuring that the interference between the corresponding interference member and the roller brush 110 meets the expected requirements.

[0249] Fig.18 In the illustrated embodiment, the first stopper 105 is located above the interference structure 120 and the liquid dispenser 130, and the second stopper 1061 is located below the interference structure 120 and the liquid dispenser 130. The interference structure 120 and the liquid dispenser 130 move between the first stopper 105 and the second stopper 1061.

[0250] When the roller brush 110 rotates forward, the interference structure 120 and the liquid distributor 130 can abut against the first limit member 105, or stay below the first limit member 105; when the roller brush 110 rotates reversely, the interference structure 120 and the liquid distributor 130 can abut against the second limit member 1061, or stay above the second limit member 1061.

[0251] like Fig.18 As shown, according to some optional embodiments, the shell 140 includes: an upper shell 141, a lower shell 142 and a bracket 106, and an air duct 104 is provided between the upper shell 141 and the lower shell 142; the bracket 106 is connected to the lower shell 142 and is located above the air duct 104, and the bracket 106 is configured to carry the interference structure 120 and the dispenser 130, and the interference structure 120 and the dispenser 130 are rotatably embedded between the upper shell 141 and the bracket 106.

[0252] In this way, after the interference structure 120 and the liquid distributor 130 are installed on the lower shell 142, covering the upper shell 141 can not only realize the connection between the upper shell 141 and the lower shell 142, but also limit the interference structure 120 and the liquid distributor 130, thereby facilitating the assembly of the floor brush structure 100.

[0253] like Figure 3 and Fig.18 As shown, the first limiting member 105 is clamped and fixed between the upper shell 141 and the interference structure 120 , and the second limiting member 1061 can be a partial structure of the bracket 106 protruding toward the roller brush 110 .

[0254] The rotating shaft 170 is clamped between the upper shell 141 and the lower shell 142. The interference structure 120 and the dispenser 130 can rotate around the axis of the rotating shaft 170. The bracket 106 has a supporting and bearing function for the interference structure 120 and the dispenser 130 to ensure the reliability of the installation and the smoothness of the movement of the interference structure 120 and the dispenser 130.

[0255] The bracket 106 may be fixed to the lower housing 142 by fasteners such as screws or bolts.

[0256] like Figure 3 , Fig.12 and Fig.13 As shown, the floor brush structure 100 further includes a seal 180 connected to the interference structure 120 . The seal 180 is a rectangular annular seal ring. The seal 180 is sleeved on the interference structure 120 and is located between the bracket 106 and the interference structure 120 .

[0257] The lower shell 142 , the bracket 106 and the interference structure 120 together form a portion of the inner wall of the air duct 104 . The seal 180 is configured to form a seal at least at the connection between the lower shell 142 and the interference structure 120 to ensure the sealing of the air duct 104 .

[0258] In an embodiment not shown in the figures of the present disclosure, the floor brush structure 100 also includes: a third driving component, the third driving component and the rotating shaft 170 are both connected to the liquid separator 130, the first interference member 121 and the second interference member 122 are both connected to the liquid separator 130 and are respectively located on the upper and lower sides of the first liquid outlet 1321; the liquid separator 130 can rotate around the rotating shaft 170 under the action of external force to respectively adjust the interference between the first interference member 121 and the roller brush 110, and the interference between the second interference member 122 and the roller brush 110.

[0259] The liquid distributor 130 can be driven by the third driving assembly to move toward the roller brush 110 to keep the interference between the first interference member 121 and the roller brush 110 within a first preset range, and the interference between the second interference member 122 and the roller brush 110 within a second preset range.

[0260] The third driving assembly can maintain the interference between the first interference member 121 and the second interference member 122 and the roller brush 110, thereby reducing the impact caused by the insufficient interference between the interference structure 120 and the roller brush 110 due to the reduction in diameter of the roller brush 110 caused by wear.

[0261] Moreover, in this embodiment, the external force driving the movement of the liquid dispenser 130 and the interference structure 120 is independent of the third driving component. The external force driving the movement of the interference structure 120 and the liquid dispenser 130 can come from the roller brush 110, or from the first driving component, the second driving component or the first roller brush cover 160.

[0262] For example, the first preset range may be represented by the distance between the first interference member 121 and the roller 111 , and the second preset range may be represented by the distance between the second interference member 122 and the roller 111 .

[0263] The floor brush structure 100 of the cleaning device of the disclosed embodiment may refer to the floor brush structure 100 described in any of the above embodiments.

[0264] In addition, the cleaning equipment also includes a control system, a power supply component and a communication system. The power supply component is configured to provide power to the control system, the communication system and the electrical components in the cleaning equipment that require electricity. The control system includes a controller or control buttons, etc. The controller can receive the user's operating instructions through the control buttons and execute the corresponding instructions. Moreover, the controller can also issue reminders to remind the user to replace the cleaning medium, deal with dirt, charge or self-clean, etc. The communication system can establish a wireless communication connection with an external mobile device to receive operating instructions from an external mobile device, or send relevant reminders to an external mobile device. External mobile devices include but are not limited to mobile phones, computers, televisions or wearable devices.

[0265] The cleaning device also includes a base station that is independent of the body 200 and the floor brush structure 100, and the base station can be used to charge the body 200, self-clean the roller brush 110, and other operations.

[0266] The present disclosure also provides a method for controlling a cleaning device. Fig. 22 As shown, the control method includes the following steps:

[0267] S10, obtaining the cleanliness of a preset position;

[0268] S20, in response to the cleanliness being greater than or equal to the first threshold, controlling the roller brush 110 to rotate forward;

[0269] S30 , in response to the cleanliness being less than the first threshold, controlling the roller brush 110 to reverse.

[0270] The cleanliness level is greater than or equal to the first threshold, indicating that the surface to be cleaned is relatively clean with less stains, and the expected cleaning effect can be achieved by the forward rotation of the roller brush 110 .

[0271] When the cleanliness is less than the first threshold, it indicates that there are many stains on the surface to be cleaned. At this time, the roller brush 110 is controlled to reverse and the bristles 112 are turned up, which can better clean stubborn stains and improve the cleaning effect and cleaning efficiency.

[0272] For example, the cleanliness can be assigned a value of 0-100%, and a larger percentage value indicates a larger cleanliness and a cleaner surface to be cleaned; conversely, a smaller percentage value indicates a smaller cleanliness and a dirtier surface to be cleaned. Without limitation, the first threshold value can be any value of 50% or less.

[0273] The preset position may be the roller brush 110, the air duct 104, the first roller brush cover 160, or the surface to be cleaned, but is not limited thereto.

[0274] A sensor may be provided on the roller brush 110, the air duct 104, the first roller brush cover 160 or the housing 140, and the sensor may be used to detect the degree of dirtiness to indicate the cleanliness of the corresponding position. The sensor may be an infrared sensor or other photoelectric sensor.

[0275] At the same time, the dirt sensor in the sewage suction pipe in the current fuselage can also be used for detection and control.

[0276] After step S30 , the control method includes: S40 , after the roller brush 110 reverses for a first preset number of revolutions or the roller brush 110 reverses for a first preset time, controlling the roller brush 110 to stop reversing.

[0277] Step S20 , step S30 and step S40 may be executed by a controller of the cleaning device or may be manually operated by a user.

[0278] In some optional embodiments, the floor brush structure 100 includes two roller brushes, and step S30 includes: in response to the cleanliness being less than the first threshold, controlling one of the two roller brushes to rotate in reverse, while the other roller brush keeps rotating in the forward direction. This can ensure the cleaning effect and reduce the resistance caused by the roller brush reversal to the user pushing the cleaning device forward, thereby improving the user experience.

[0279] In some optional embodiments, the control method of the cleaning device further includes the steps of:

[0280] S50, determining whether there is a stubborn stain;

[0281] S60, in response to the presence of stubborn stains, controlling the roller brush to reverse;

[0282] S70, controlling the roller brush to reverse to a second preset number of revolutions and then stop reversing, or controlling the roller brush to reverse to a second preset time and then stop reversing;

[0283] S80, controlling the roller brush to rotate forward;

[0284] S90, controlling the roller brush to rotate forward to a third preset number of revolutions and then stop rotating forward, or controlling the roller brush to rotate forward to a third preset time and then stop rotating forward;

[0285] S100, controlling the roller brush to reverse again, and reducing the amount of liquid sprayed by the liquid distributor 130, or stopping the liquid distributor 130 from spraying liquid.

[0286] The amount of liquid sprayed by the dispenser 130 in step S60 and step S80 is greater than the amount of liquid sprayed by the dispenser 130 in step S80. Therefore, before step S100, the stubborn stains have been softened by more cleaning media, and executing step S100 can reduce or even stop spraying liquid. This not only effectively ensures the cleaning effect, but also reduces the residual liquid on the ground.

[0287] Step S80 is forward rotation to restore the motor that controls the rotation of the roller brush.

[0288] After step S40, step S10 may be executed again, and the cycle continues.

[0289] Optionally, step S50 includes: recording the number of times the cleanliness is less than the first threshold, and if the number is greater than or equal to the second threshold, determining that stubborn stains exist; if the number is less than the second threshold, determining that stubborn stains do not exist. Each time steps S10 to S40 are cycled once, if the cleanliness is less than the first threshold once, the number of times is incremented by 1.

[0290] Without limitation, the second threshold may be 2, 3, or 4.

[0291] In step S20 and step S30, the movement of the liquid distributor 130 and the interference structure 120 are driven by the roller brush. If the floor brush structure 100 has a first roller brush cover 160 connected to the interference structure 120, then in step S20, after the roller brush rotates forward, the interference structure 120 will drive the first roller brush cover 160 to separate from the roller brush; in step S30, after the roller brush rotates reversely, the interference structure 120 will drive the first roller brush cover 160 to contact the roller brush, so as to use the rotation of the roller brush to clean the dirt on the first roller brush cover 160.

[0292] In some embodiments, the movement of the dispenser 130 and the interference structure 120 is not driven by a roller brush, then:

[0293] Step S20 includes step S21, in response to the cleanliness being greater than or equal to the first threshold, controlling the roller brush to rotate forward, and controlling the preset driving assembly to drive the liquid distributor 130 and the interference structure 120 to move, so that the interference between the first interference member 121 and the roller brush is smaller than the interference between the second interference member 122 and the roller brush;

[0294] Step S30 includes step S31, in response to the cleanliness being less than the first threshold, controlling the roller brush to reverse, and controlling the preset driving component to drive the liquid dispenser 130 and the interference structure 120 to move, so that the interference between the first interference member 121 and the roller brush is greater than the interference between the second interference member 122 and the roller brush. The preset driving component can be the first driving component or the second driving component.

[0295] When the preset driving component is the second driving component, a sensor for detecting dirt can be installed on the roller brush cover component, and the sensor can be used to detect the cleanliness of the inner wall of the first roller brush cover 160.

[0296] like Fig.18 As shown, in step S21, the second driving component is controlled to first drive the first roller brush cover 160 to move upward to separate from the roller brush, and then the first roller brush cover 160 drives the interference structure 120 to rotate clockwise, so that the interference amount between the first interference member 121 and the roller brush is smaller than the interference amount between the second interference member 122 and the roller brush. In step S31, the second driving component is controlled to first drive the first roller brush cover 160 to move downward to contact with the roller brush, and then the first roller brush cover 160 drives the interference structure 120 to rotate counterclockwise, so that the interference amount between the first interference member 121 and the roller brush is larger than the interference amount between the second interference member 122 and the roller brush.

[0297] The embodiments of the present disclosure also provide an apparatus, a computer-readable storage medium or a computer program product for implementing the above-mentioned cleaning equipment control method.

[0298] Among them, the cleaning equipment control device includes: an acquisition module and a processing module electrically connected to the acquisition module, the acquisition module is used to obtain the cleanliness of a preset position; the processing module is used to control the roller brush to rotate forward in response to the cleanliness being greater than or equal to a first threshold; or, in response to the cleanliness being less than the first threshold, control the roller brush to rotate reversely.
