Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a floor brush, a cleaning equipment and a cleaning system. Background Art

[0002] With the development of science and technology and the improvement of people's quality of life, cleaning equipment is increasingly used in people's lives.

[0003] The use of cleaning equipment has greatly reduced the burden of manpower, but when cleaning stubborn stains, cleaning equipment still cannot change different cleaning methods like manual cleaning to remove stubborn stains.

[0004] For this reason, the cleaning of stubborn stains has become a problem that needs to be solved urgently by current cleaning equipment. Utility Model Content

[0005] The present application provides a floor brush, a cleaning device and a cleaning system. The floor brush can clean stubborn stains and has high cleaning efficiency and good cleaning effect.

[0006] A first aspect of an embodiment of the present application provides a floor brush, comprising:

[0007] case;

[0008] A roller brush is mounted on the housing;

[0009] A brush plate assembly, comprising a movable lifting mechanism and a brush plate, wherein the movable lifting mechanism is mounted on the housing, the brush plate is connected to the movable lifting mechanism, and the movable lifting mechanism is used to drive the brush plate to lift and reciprocate;

[0010] A liquid supply assembly is disposed in the housing, the liquid supply assembly includes a first liquid supply pipe and a second liquid supply pipe, the liquid supply assembly provides cleaning liquid to the brush plate assembly or the surface to be cleaned through the first liquid supply pipe, and the liquid supply assembly provides cleaning liquid to the roller brush through the second liquid supply pipe;

[0011] a first water distributor, connected to the first liquid supply pipe, for providing cleaning liquid to the surface to be cleaned or the brush plate assembly;

[0012] The second water distributor is connected to the second liquid supply pipe and is used for spraying cleaning liquid to the roller brush.

[0013] The above has introduced the method for cleaning stubborn stains. Furthermore, the floor brush is provided with a roller brush and a second water divider for wetting the roller brush, and is also provided with a brush plate assembly and a first water divider used in conjunction therewith.

[0014] In actual application, since the roller brush is at the front end of the floor brush, when it is pushed forward, the stain is first cleaned for the first time by the wet roller brush, and then cleaned for the second time by the brush plate assembly after the first cleaning. That is to say, through the above scheme, during actual cleaning, one push can make the stain be cleaned twice, and a backward pull will also pass through the brush plate assembly and the roller brush in turn, that is, the same stain will be cleaned four times with one push and pull, which doubles the cleaning efficiency compared to before.

[0015] At the same time, the brush plate assembly itself can also move back and forth. If the reciprocating movement of the brush plate itself is taken into account during one cleaning process, the same stain can be cleaned four, six, or even eight times during one push-pull cleaning process, and the overall cleaning efficiency can be directly increased by three to four times.

[0016] In this way, the stains can be dissolved first by the liquid supply component. While the stains are being dissolved, the brush plate component and the roller brush can be pushed and pulled to achieve rapid dissolution and rapid cleaning of stubborn stains.

[0017] Moreover, the liquid supply component supplies water to the first water distributor and the second water distributor at the same time, and there is no need to configure a separate water supply component for water supply, which can save a certain cost and also make the structure more compact.

[0018] In a possible implementation, at least one liquid outlet is provided on the housing or the brush plate, the liquid outlet is communicated with the liquid supply assembly, and the cleaning liquid is sprayed out through the liquid outlet.

[0019] In this way, the cleaning liquid can be sprayed onto the surface to be cleaned through the liquid outlet hole, so that the cleaning liquid can fully and completely soak the stains on the surface to be cleaned, and the cleaning efficiency and cleaning effect of the wiping plate can be effectively improved.

[0020] In a possible implementation, there are multiple liquid outlet holes, which are arranged at intervals along the length direction of the brush plate, and the liquid outlet holes cover the entire length direction of the brush plate. This can increase the amount of liquid discharged from the liquid outlet holes, and each area under the brush plate can always be sprayed with the cleaning liquid sprayed from the liquid outlet holes, so that the cleaning liquid can soak the stains in the area where the brush plate passes, so that the brush plate can clean it, which can effectively improve the cleaning effect of the brush plate on stains.

[0021] In a possible implementation, the liquid outlet is located on the housing and in front of the brush plate along the moving direction of the floor brush. In this way, when the floor brush moves, the cleaning liquid sprayed from the liquid outlet can first soak the stains in front of the brush plate. When the brush plate moves onto the stains, the stains have been soaked by the cleaning liquid, which makes it easier for the brush plate to remove the stains.

[0022] In a possible implementation, the first water distributor has a first liquid storage chamber, and the first liquid storage chamber is connected to the first liquid supply pipe and the liquid outlet hole respectively.

[0023] In a possible implementation, a water outlet is provided on the first water distributor, and the water outlet is communicated with the first liquid storage chamber;

[0024] The number of the water outlets is the same as the number of the liquid outlet holes, and the water outlets are aligned with the liquid outlet holes respectively.

[0025] In a possible implementation, the liquid outlet hole extends obliquely toward the brush plate from an end of the liquid outlet hole facing away from the surface to be cleaned to an end of the liquid outlet hole facing the surface to be cleaned.

[0026] In this way, the liquid outlet can guide the spraying direction of the cleaning liquid, and the cleaning liquid sprayed from the liquid outlet can be sprayed in the direction of the brush plate. The stains in the corresponding area below the brush plate can be soaked so that the brush plate can clean the stains, which can effectively improve the cleaning effect of the brush plate on the stains. Moreover, under the guidance of the liquid outlet, the cleaning liquid can also be sprayed toward the brush plate to wet the brush plate, so that when the brush plate cleans the surface to be cleaned, the cleaning liquid on the brush plate can also soak the stains on the surface to be cleaned, so as to reduce the adhesion of the stains, thereby improving the cleaning effect of the brush plate on the stains.

[0027] In addition, a wet brush disc can also reduce the friction between the brush disc and the surface to be cleaned, which helps to reduce the wear of the brush disc and increase the service life of the brush disc.

[0028] In a possible implementation, the cross-sectional area of ​​an end of the liquid outlet hole away from the surface to be cleaned is greater than the cross-sectional area of ​​an end of the liquid outlet hole close to the surface to be cleaned.

[0029] By narrowing the cross-sectional area of ​​the liquid outlet hole near the end of the surface to be cleaned, the pressure of the cleaning liquid sprayed from the liquid outlet hole can be increased, the flow rate of the cleaning liquid can be increased, and the spray range of the cleaning liquid can be expanded, which helps to spray the cleaning liquid in the form of mist. This is conducive to the cleaning liquid quickly penetrating into the stains to fully and completely immerse the stains. Therefore, the brush plate assembly can quickly and thoroughly remove the stains, improve the cleaning efficiency of the brush plate assembly, and enhance the cleaning effect of the brush plate assembly.

[0030] In a possible implementation, the cross-sectional area of ​​the liquid outlet gradually decreases from the end of the liquid outlet facing away from the surface to be cleaned to the end of the liquid outlet facing the surface to be cleaned. This can avoid the liquid outlet having an obvious diameter change portion, avoid stress concentration in the liquid outlet, prevent cracks or damage in the liquid outlet, and help to ensure the service life of the floor brush.

[0031] A second aspect of the embodiments of the present application provides a floor brush, including:

[0032] case;

[0033] A brush plate assembly, comprising a movable lifting mechanism and a brush plate, wherein the movable lifting mechanism is mounted on the housing, the brush plate is connected to the movable lifting mechanism, and the movable lifting mechanism is used to drive the brush plate to lift and reciprocate;

[0034] A liquid supply assembly is arranged in the shell, and is used to provide cleaning liquid to the surface to be cleaned or the brush plate assembly.

[0035] The embodiment of the present application enables the brush plate in the brush plate assembly to be raised and lowered and reciprocated, that is, when the brush plate is needed, the brush plate assembly is lowered to the working position and the brush plate is reciprocated to clean the surface to be cleaned, which can effectively clean stubborn stains and improve the cleaning effect of the cleaning equipment.

[0036] When the brush disc assembly is not needed, the brush disc assembly is raised to the stowed position to avoid the brush disc assembly always contacting the surface to be cleaned, which can effectively reduce the wear of the brush disc assembly. Moreover, the friction resistance between the floor brush and the surface to be cleaned is reduced, which is conducive to keeping the floor brush moving smoothly on the surface to be cleaned.

[0037] In addition, the liquid supply component can be used to soak the stains on the surface to be cleaned or the liquid can be sprayed onto the brush plate component and then the brush plate component can be used to clean the surface to be cleaned. This can efficiently clean stubborn stains on the surface to be cleaned and effectively improve the cleaning effect of stubborn stains.

[0038] In one possible implementation, it also includes:

[0039] An auxiliary lifting mechanism, the brush plate is also connected to the auxiliary lifting mechanism;

[0040] The mobile lifting mechanism and the auxiliary lifting mechanism are respectively connected to opposite ends of the brush plate, and the auxiliary lifting mechanism is used to assist the mobile lifting mechanism in driving the brush plate to lift. This can improve the uniformity of the force on the brush plate, reduce or avoid the tilting of the brush plate during the lifting process, and is conducive to improving the stability and reliability of the brush plate lifting.

[0041] In a possible implementation, the auxiliary lifting mechanism includes:

[0042] A second drive structure;

[0043] a second eccentric wheel connected to the second driving structure;

[0044] A lifting assembly is in contact with the outer edge of the second eccentric wheel and is connected to the brush plate, the second driving structure drives the second eccentric wheel to rotate, the second eccentric wheel drives the lifting assembly to rise and fall, and the lifting assembly drives the brush plate to rise and fall;

[0045] The second driving structure is configured to drive the second eccentric wheel to rotate in two opposite directions along a third direction or a fourth direction;

[0046] When the second eccentric wheel rotates along the third direction, the second eccentric wheel drives the lifting assembly to descend;

[0047] When the second eccentric wheel rotates along the fourth direction, the second eccentric wheel drives the lifting assembly to rise.

[0048] When the mobile lifting mechanism needs to drive the brush plate to descend, the second driving structure in the auxiliary lifting mechanism can drive the second eccentric wheel to rotate in the third direction, so that the second eccentric wheel can drive the brush plate to descend synchronously through the lifting assembly. Correspondingly, when the mobile lifting mechanism needs to drive the brush plate to ascend, the second driving structure in the auxiliary lifting mechanism can drive the second eccentric wheel to rotate in the fourth direction, so that the second eccentric wheel can drive the brush plate to ascend synchronously through the lifting assembly.

[0049] In one possible implementation, the lifting assembly includes:

[0050] A first guide rod extends along the lifting direction of the brush plate and is slidably matched with the housing, and one end of the first guide rod is connected to the brush plate;

[0051] A support plate is connected to the other end of the first guide rod, and the support plate is also in contact with the second eccentric wheel.

[0052] Through the cooperation of the first guide rod and the support plate, the first guide rod can play a guiding role, so that the brush plate can be smoothly lifted and lowered along the first guide rod, which can reduce or avoid the tilting or deviation of the brush plate during the lifting process, and help to improve the smoothness of the brush plate lifting.

[0053] In a possible implementation, the housing has a first guide structure, and the first guide rod is inserted into the first guide structure and slidably cooperates with the first guide structure.

[0054] In a possible implementation, the first guide structure includes:

[0055] A first guide enclosure connected to the housing;

[0056] a first guide member, wherein the first guide rod is inserted into the first guide member and slidably cooperates with the first guide member;

[0057] One of the first guide enclosure and the first guide member has a first slide groove, and the other has a first slider. The first slider is slidably connected to the first slide groove, and the sliding trajectory of the first guide member is the same as the reciprocating movement trajectory of the brush plate.

[0058] During the reciprocating movement of the brush plate, the first guide member and the first guide enclosure can slide relative to each other through the cooperation between the first slider and the first slide groove, so that the first guide member can slide reciprocally synchronously with the brush plate, which helps to improve the reliability and stability of the reciprocating movement of the brush plate.

[0059] In one possible implementation, the first sliding groove is located on an inner wall of the first guide enclosure, and the first sliding block is located on an outer periphery of the first guide member.

[0060] In one possible implementation, it also includes:

[0061] The first elastic member is abutted between the first guide structure and the brush plate. The elastic force generated by the first elastic member acts on the brush plate, so that the brush plate can be in close contact with the surface to be cleaned, thereby ensuring the cleaning effect of the brush plate on the surface to be cleaned.

[0062] A third aspect of an embodiment of the present application provides a floor brush, including:

[0063] case;

[0064] A brush plate assembly, comprising a movable lifting mechanism and a brush plate, wherein the movable lifting mechanism is mounted on the housing, the brush plate is connected to the movable lifting mechanism, and the movable lifting mechanism is used to drive the brush plate to lift and reciprocate;

[0065] A liquid supply assembly, disposed in the housing, and used to supply cleaning liquid to the surface to be cleaned or the brush plate assembly;

[0066] The brush plate comprises:

[0067] A base connected to the mobile lifting mechanism;

[0068] The cleaning part is detachably connected to the base.

[0069] The present case also provides a solution that can perform targeted cleaning for different environments on the basis of cleaning stubborn stains. Specifically, by setting the cleaning part in a detachable form, it can be cleaned according to different stains during actual cleaning. For example, for stubborn stains, such as rice grains, a brush with higher hardness can be replaced for targeted cleaning. For example, for water stains, the current effect of using a brush is poor, and it can be replaced with an absorbent mop, which can be used for wiping while cleaning.

[0070] In a possible implementation, the cleaning portion is provided with bristles, and the bristles are evenly distributed along the width direction and the length direction of the brush plate and cover the side of the brush plate facing away from the movable lifting mechanism.

[0071] In a possible implementation, the cleaning part is a rag, and the rag covers the side of the brush plate facing away from the movable lifting mechanism.

[0072] Two application methods are introduced above. One is to set bristles on the cleaning part so that a better cleaning effect can be obtained by controlling its movement; the other is to set a rag, which can wipe or absorb part of the liquid while cleaning the stains, so that the residual water stains on the ground are reduced.

[0073] In one possible implementation, it also includes:

[0074] A detection member, mounted on the brush plate or the housing, and electrically connected to the movable lifting mechanism and the liquid supply assembly;

[0075] The detection member is configured to identify stains on the work surface, and start the brush plate assembly and the liquid supply assembly when the stains are identified, and shut down the brush plate assembly and the liquid supply assembly when it is identified that the stains are removed.

[0076] By configuring a detection component on the floor brush, the detection component can automatically identify stains on the surface to be cleaned, and then the brush disc assembly can be automatically controlled without manual operation to start and close the brush disc assembly and the liquid supply assembly. In this way, the control of the brush disc assembly and the liquid supply assembly is more automated and intelligent, which can reduce the user's operating difficulty and improve the control performance of the cleaning equipment.

[0077] In a possible implementation, the detection member is disposed in a central area of ​​the brush plate, or the detection member is disposed in the housing.

[0078] In this way, the detection range of the detection part corresponds to the coverage range of the brush plate, and the operation of the brush plate assembly can be accurately controlled so that the brush plate falls exactly on the stains on the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the brush plate assembly.

[0079] In a possible implementation, the detection element includes at least one of an infrared sensor and a camera.

[0080] In one possible implementation, it also includes:

[0081] A control component is electrically connected to the movable lifting mechanism and the detection component; the control component is configured to control the brush plate assembly and the liquid supply assembly to start or shut down according to a control signal sent by the detection component.

[0082] In a possible implementation, the mobile lifting mechanism includes:

[0083] A first driving structure;

[0084] A rotating member connected to the first driving structure, wherein the first driving structure drives the rotating member to rotate;

[0085] A lifting and rotating member connected to the brush plate and the rotating member;

[0086] Wherein, the first driving structure is configured to drive the rotating member to rotate in two opposite directions, a first direction or a second direction;

[0087] When the rotating member rotates along the first direction, the lifting rotating member first descends to a designated position and then is driven to rotate by the rotating member; when the lifting rotating member descends, the lifting rotating member drives the brush plate to descend; when the lifting rotating member rotates, the lifting rotating member drives the brush plate to reciprocate;

[0088] When the rotating member rotates along the second direction, the lifting rotating member rises, and the lifting rotating member drives the brush plate to rise.

[0089] In a possible implementation, the mobile lifting mechanism further includes:

[0090] The first eccentric wheel is connected to the lifting and rotating member and is movably connected to the brush disc. When the lifting and rotating member rotates, the first eccentric wheel is driven to rotate, and the first eccentric wheel drives the brush disc to move back and forth. The first eccentric wheel can convert the rotational action of the lifting and rotating member into the reciprocating action of the brush disc, so that the brush disc can make frictional contact with the surface to be cleaned, so as to achieve the cleaning of stubborn stains on the surface to be cleaned, which can effectively improve the cleaning effect and cleaning efficiency of the brush disc on stubborn stains. At the same time, the use of the eccentric wheel can also make the overall structure more compact. It should be understood that the floor brush is a complex whole with multiple components inside. If it is driven by other methods, it is very likely that it does not have the corresponding installation space at all, or the overall structure of the floor brush will become larger, and the user experience will be poor.

[0091] In one possible implementation, one of the rotating member and the lifting rotating member is provided with a spiral groove that extends spirally continuously, and the other is provided with a spiral slider; the spiral slider is slidably connected to the spiral groove and slides along the extension direction of the spiral groove.

[0092] By providing a spiral groove on one of the rotating part and the lifting rotating part, and providing a spiral slider on the other, the spiral slider extends into the spiral groove and slides along the extension direction of the spiral groove, the rotating part can drive the lifting part to rotate, and the lifting part can be lifted and lowered relative to the rotating part.

[0093] In a possible implementation, the number of the spiral sliders is at least two, and each of the spiral sliders is arranged at intervals along the circumference of the rotating member or the lifting rotating member. By arranging at least two spiral sliders at intervals along the circumference of the rotating member or the lifting rotating member, different spiral sliders contact different parts of the spiral chute on the circumference, which can improve the stability and reliability of the movement of the lifting member relative to the rotating member. In addition, the total contact area between the spiral slider and the spiral chute is small, and the friction resistance between the two is small, which can ensure the smooth movement of the lifting member.

[0094] In a possible implementation, one of the rotating member and the lifting rotating member includes a rotating cylinder, and the other includes an inner cylinder portion and an outer cylinder portion which are arranged inside and outside, a matching space is formed between the inner cylinder portion and the outer cylinder portion, and the rotating cylinder is inserted into the matching space;

[0095] Among them, one of the spiral slider and the spiral groove is arranged on the rotating cylinder, and the other is arranged on the outer peripheral wall of the inner cylinder or the inner peripheral wall of the outer cylinder. By inserting the rotating cylinder into the annular matching space formed between the inner cylinder and the outer cylinder, the matching space guides and restricts the moving trajectory of the rotating cylinder, so that the movement trajectory of the lifting member rotating and lifting can be more accurate, thereby improving the stability of the brush disc rotating on the surface to be cleaned.

[0096] In a possible implementation, the spiral groove is provided on the inner peripheral wall of the outer cylinder portion, and the spiral sliding block is provided on the outer peripheral wall of the rotating cylinder.

[0097] In a possible implementation, the housing has a limiter, which is arranged around the outer periphery of the lifting and rotating member and frictionally cooperates with the lifting and rotating member;

[0098] The limiter is used to limit the rotation of the lifting and rotating member when the lifting and rotating member is lifted. The frictional clamping force generated by the limiter on the lifting and rotating member will prevent the lifting and rotating member from rotating, so that the lifting and rotating member is lifted and lowered under the force of the rotating member, so as to drive the brush plate to descend to the working position or rise to the stowed position.

[0099] In a possible implementation, the inner wall of the first limiter has a friction feeler, and the friction feeler is used to limit the rotation of the lifting and rotating member. The friction feeler can increase the clamping force of the limiter on the lifting and rotating member, and can effectively prevent the lifting and rotating member from rotating, so that the lifting and rotating member can be lifted.

[0100] A fourth aspect of the present application provides a cleaning device, comprising any of the floor brushes described above.

[0101] The embodiment of the present application enables the cleaning device to include the above-mentioned floor brush, thereby effectively improving the cleaning effect of the cleaning device on stubborn stains and effectively improving the cleaning efficiency of the cleaning device.

[0102] In a possible implementation, the cleaning device is a floor scrubber, and the cleaning device also includes a body, and the floor brush is connected to a bottom wall of the body.

[0103] In one possible implementation, along the travel direction of the floor brush, the roller brush is installed at the front end of the shell, and the brush plate assembly is installed behind the roller brush.

[0104] In a possible implementation, the body is provided with a clean water tank, and the clean water tank is used to provide cleaning liquid to the liquid supply assembly.

[0105] In a possible implementation, a liquid storage member is disposed in the housing of the floor brush, and the liquid storage member is used to provide cleaning liquid to the liquid supply assembly.

[0106] A fifth aspect of the present application provides a cleaning system, comprising a base station and any one of the cleaning devices described above;

[0107] The cleaning device is stored on the base station.

[0108] The embodiment of the present application enables the cleaning system to include the above-mentioned cleaning device, thereby effectively improving the cleaning effect of the cleaning device on stubborn stains and effectively improving the cleaning efficiency of the cleaning device.

[0109] In one possible implementation, the base station has a floor brush cleaning groove, which is used to clean the floor brush when the cleaning device is stored in the base station. The floor brush cleaning groove can clean the floor brush, thereby maintaining the floor brush and helping to increase the service life of the floor brush.

[0110] In one possible implementation, the floor brush cleaning tank includes:

[0111] A brush plate cleaning groove, in which the brush plate of the floor brush is located;

[0112] A roller brush cleaning groove, wherein the roller brush in the floor brush is located in the roller brush cleaning groove;

[0113] A connecting channel is connected to the brush plate cleaning tank at one end and connected to the roller brush cleaning tank at the other end, and the sewage in the brush plate cleaning tank flows into the roller brush cleaning tank through the connecting channel.

[0114] The sewage cleaned by the brush disc in the brush disc cleaning tank flows into the roller brush cleaning tank through the connecting channel. The sewage can be sucked up by the roller brush and then sucked into the sewage tank through the sewage suction pipe under the action of negative pressure for storage, thereby completing the cleaning work of the cleaning equipment.

[0115] In a possible implementation, an end of the connecting channel communicating with the brush plate cleaning groove is higher than an end of the connecting channel communicating with the roller brush cleaning groove.

[0116] In this way, the sewage can flow into the roller brush cleaning groove under the action of gravity, so that the sewage can be sucked into the sewage tank in the roller brush cleaning groove, which can reduce or avoid the accumulation of sewage in the brush plate cleaning groove, help to improve the cleanliness of the brush plate cleaning groove, and enhance the cleaning effect of the base on the floor brush.

[0117] In a possible implementation, the height of the connecting channel gradually decreases from one end of the connecting channel connected to the brush plate cleaning groove to the end of the connecting channel connected to the roller brush cleaning groove.

[0118] In this way, the sewage in the brush plate cleaning tank can flow evenly into the roller brush cleaning tank, which can improve the smoothness of sewage flow. In addition, it can also reduce or avoid the accumulation of sewage due to the high and low parts of the connecting channel, which helps to improve the reliability of sewage flowing to the roller brush cleaning tank, thereby effectively improving the cleaning effect of the base station.

[0119] In a possible implementation, a cleaning contact is provided on the bottom of the brush plate cleaning groove, and the cleaning contact is in frictional contact with the brush plate. During the cleaning process of the brush plate, the brush plate moves back and forth and can rub back and forth with the cleaning contact, so that the cleaning contact can clean the brush plate, thereby effectively improving the cleaning effect of the brush plate.

[0138] As described in the background art, existing cleaning equipment is still unable to change different cleaning methods like manual cleaning, and is unable to effectively remove stubborn stains.

[0139] In order to solve the above problems, the embodiments of the present application provide a floor brush, a cleaning device and a cleaning system, by making the brush plate in the brush plate assembly rise and fall and reciprocate, that is, when the brush plate is needed, the brush plate assembly is lowered to the working position and the brush plate is reciprocated to clean the surface to be cleaned, which can effectively clean stubborn stains and improve the cleaning effect of the cleaning device.

[0140] When the brush disc assembly is not needed, the brush disc assembly is raised to the stowed position to avoid the brush disc assembly from always contacting the surface to be cleaned, which can effectively reduce the wear of the brush disc assembly. Moreover, the friction resistance between the floor brush and the surface to be cleaned is reduced, which is conducive to keeping the floor brush moving smoothly on the surface to be cleaned. In addition, the liquid supply assembly can be used to wet the stains on the surface to be cleaned, so that stubborn stains on the surface to be cleaned can be efficiently cleaned, which can effectively improve the cleaning effect of stubborn stains.

[0141] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0142] An embodiment of the present application provides a cleaning device, which can be a household handheld floor scrubber. In this way, a better cleaning effect can be achieved by utilizing a lifting brush disc assembly in conjunction with the reciprocating movement of the brush disc. Water spilled during cleaning by the brush disc assembly can be sucked up by the suction port at the front end of the roller brush. With the cooperation of the two, cleaning in multiple scenarios can be achieved.

[0143] In the embodiment of the present application, a floor scrubber is taken as the above-mentioned cleaning equipment for explanation.

[0144] The cleaning equipment is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a floor, a wall, or the surface of an object to be cleaned with different degrees of roughness. The embodiment of the present application does not specifically limit the type of the surface to be cleaned.

[0146] See also Figure 1 and Figure 2 As shown, the cleaning device may include a floor brush 1. When working, the cleaning device moves on the surface to be cleaned, and the surface to be cleaned is cleaned by the floor brush 1 contacting and rubbing with the surface to be cleaned.

[0147] The cleaning device may also include a body (not shown in the figure), and the floor brush 1 may be connected to the bottom of the body. The body may be equipped with components such as a clean water tank and a dirty water tank. The clean water tank is used to hold cleaning liquid. When the cleaning device is working, the cleaning liquid in the clean water tank is sprayed on the floor brush 1 or the floor brush 1 (in the direction of travel of the cleaning device, Figure 1 or Figure 2 The surface to be cleaned is cleaned in front of the floor brush 1 (in the X direction) to cooperate with the floor brush 1 to clean the surface to be cleaned. The sewage on the surface to be cleaned (together with foreign matter such as particles and hair) is sucked into the sewage tank, thereby completing the cleaning process.

[0148] See also Figure 1 and Figure 2 As shown, the floor brush 1 may include a shell 100, a roller brush 200 and a running wheel 300. The shell 100 is the main support structure of the floor brush 1, and the roller brush 200 and the running wheel 300 may be both installed on the shell 100. When the cleaning device performs cleaning work, the roller brush 200 contacts the surface to be cleaned, and the motor (not shown in the figure) installed in the shell 100 drives the roller brush 200 to rotate at a high speed, so that the roller brush 200 can make friction contact with the surface to be cleaned to clean the surface to be cleaned. The running wheel 300 contacts the surface to be cleaned and rolls along the surface to be cleaned to assist the cleaning device in walking on the surface to be cleaned, which can improve the stability of the floor brush 1 walking on the surface to be cleaned.

[0149] Among them, along the moving direction of the floor brush 1, the roller brush 200 can be installed at the front end of the housing 100, and the running wheel 300 can be installed at the rear end of the housing 100. This makes it easy to control the moving direction of the floor brush 1, which is conducive to maintaining the balance of the floor brush 1 during the moving process. Moreover, the roller brush 200 preferentially contacts the surface to be cleaned, and there is no obstruction in front of the roller brush 200, which is conducive to the roller brush 200 cleaning the surface to be cleaned.

[0150] An auxiliary wheel 400 may also be installed on the housing 100. The auxiliary wheel 400 may be located on the side of the housing 100 facing the surface to be cleaned. The auxiliary wheel 400 may contact the surface to be cleaned and roll along the surface to be cleaned. The auxiliary wheel 400 may make the floor brush 1 walk more steadily and smoothly on the surface to be cleaned. The auxiliary wheel 400 may be located between the running wheel 300 and the roller brush 200. For example, the auxiliary wheel 400 may be arranged close to the roller brush 200, and the distance between the auxiliary wheel 400 and the running wheel 300 is larger, which is conducive to enhancing the balance of the floor brush 1.

[0151] Continue to see 1 and Figure 2 As shown, the floor brush 1 of this embodiment may further include a brush plate assembly 500, which may be mounted on the housing 100. The friction between the brush plate assembly 500 and the surface to be cleaned is greater, and the brush plate assembly 500 may be used to clean stubborn stains on the surface to be cleaned. For example, the stubborn stains may be stains with strong adhesion, thicker stains, heavier stains, etc.

[0152] For example, the brush plate assembly 500 can be arranged along the height direction of the floor brush 1 ( Figure 1 or Figure 2 The brush plate assembly 500 can be raised and lowered in the Z direction (in the Z direction) to control the relative position between the brush plate assembly 500 and the surface to be cleaned. For example, the brush plate assembly 500 can have a working position and a stowed position. When it is necessary to clean stubborn stains, the brush plate assembly 500 can be lowered to the working position. At this time, the brush plate assembly 500 can contact the surface to be cleaned to clean the surface to be cleaned.

[0153] When the stubborn stains are cleaned, the brush plate assembly 500 can rise and return to the retracted position. At this time, the brush plate assembly 500 is away from the surface to be cleaned, that is, there is a distance between the brush plate assembly 500 and the surface to be cleaned, which can avoid friction between the brush plate assembly 500 and the surface to be cleaned.

[0154] Combination Figure 3 As shown, the brush plate assembly 500 may include a movable lifting mechanism 510 and a brush plate 520. The movable lifting mechanism 510 may be used to drive the brush plate 520 to lift and reciprocate, and the brush plate 520 may be used to clean the surface to be cleaned.

[0155] For example, the mobile lifting mechanism 510 may be mounted on the housing 100, and the brush plate 520 may be connected to the mobile lifting mechanism 510. For example, at least a portion of the structure of the mobile lifting mechanism 510 may be accommodated in the housing 100, the brush plate 520 may be connected to the bottom end of the mobile lifting mechanism 510, and the brush plate 520 may be exposed outside the housing 100 so as to contact the surface to be cleaned.

[0156] When the brush plate assembly 500 is in the working position, the mobile lifting mechanism 510 can first lower the brush plate 520 so that the brush plate 520 can contact the surface to be cleaned. After the brush plate 520 is lowered, the brush plate 520 can be reciprocated so that the brush plate 520 can reciprocate and rub the surface to be cleaned to increase the friction between the surface to be cleaned, thereby cleaning the stubborn stains attached to the surface to be cleaned.

[0157] When the stubborn stains are cleaned, the mobile lifting mechanism 510 can stop the brush plate 520 from reciprocating and lift the brush plate 520 to the retracted position to end the work of the brush plate assembly 500 .

[0158] Continue to see Figure 3 As shown, the floor brush 1 may further include a liquid supply assembly 700, and at least part of the structure of the liquid supply assembly 700 may be disposed in the housing 100, for example, at least part of the structure or components of the liquid supply assembly 700 may be located in the accommodation space of the housing 100. The liquid supply assembly 700 may be used to provide cleaning liquid to the surface to be cleaned and the brush plate assembly. For example, the cleaning liquid may be sprayed on the surface to be cleaned to wet the surface to be cleaned, or the cleaning liquid may also be sprayed toward the brush plate assembly 500 to wet the brush plate assembly 500, for example, it may be sprayed on the brush plate 520 in the brush plate assembly 500 to wet the brush plate 520.

[0159] The cleaning liquid can soak the stubborn stains on the surface to be cleaned, which can reduce the adhesion strength of the stains on the surface to be cleaned, and can also make the stains themselves softer. Alternatively, the cleaning liquid is sprayed on the brush plate assembly 500, and after the brush plate 500 in the brush plate assembly 500 is wetted, when the brush plate 520 cleans the surface to be cleaned, the wet brush plate 520 can also soak the stains on the surface to be cleaned. In this way, it is convenient for the brush plate 520 to clean the stains, and the cleaning efficiency of the brush plate 520 can be improved, and the cleaning effect of the brush plate 520 on stubborn stains can be improved. For example, when the stains attached to the surface to be cleaned are dry garbage, the stains can be softened and the adhesion strength of the stains can be reduced by soaking the stains with the cleaning liquid, so that the stains can be cleaned and removed thoroughly.

[0160] Moreover, the cleaning liquid can also play a lubricating effect between the brush plate 520 and the surface to be cleaned, which can reduce the friction between the brush plate 520 and the surface to be cleaned, and avoid scratching the surface to be cleaned, especially for plastic floors, wooden floors and other surfaces to be cleaned that are easily scratched. At the same time, it will also reduce the wear on the brush plate 520 itself, which helps to extend the service life of the brush plate 520.

[0161] The liquid supply assembly 700 can also provide cleaning liquid to the roller brush 200, so as to wet the roller brush 200 or the surface to be cleaned at the roller brush 200 with the cleaning liquid, thereby helping the roller brush 200 to thoroughly clean the surface to be cleaned.

[0162] The embodiment of the present application enables the brush plate 520 in the brush plate assembly 500 to be raised and lowered and reciprocated. That is, when the brush plate 520 is needed, the brush plate assembly 500 is lowered to the working position and the brush plate 520 is reciprocated to clean the surface to be cleaned. This can effectively clean stubborn stains and improve the cleaning effect of the cleaning equipment.

[0163] When the brush disc assembly 500 is not needed, the brush disc assembly 500 is raised to the stowed position to avoid the brush disc assembly 500 from always contacting the surface to be cleaned, which can effectively reduce the wear of the brush disc assembly 500. Moreover, the friction resistance between the floor brush 1 and the surface to be cleaned is reduced, which is conducive to keeping the floor brush 1 moving smoothly on the surface to be cleaned. In addition, the liquid supply assembly 700 can be used to soak the stains on the surface to be cleaned, or the cleaning liquid can be sprayed onto the brush disc assembly 500 and then the brush disc assembly 500 can be used to clean the surface to be cleaned, so that the stubborn stains on the surface to be cleaned can be cleaned efficiently, which can effectively improve the cleaning effect of stubborn stains.

[0164] See also Figure 2 As shown, along the traveling direction of the cleaning device, the brush plate 520 can be installed at the front end of the housing 100, and the brush plate assembly 500 can be located behind the roller brush 200, for example, the brush plate assembly 500 can be located between the roller brush 200 and the running wheel 300. In this way, the brush plate assembly 500 does not occupy additional space, and the spatial layout of the floor brush 1 can be made more reasonable and compact, which is conducive to the miniaturized design of the floor brush 1.

[0165] Continue to see Figure 3 As shown, the housing 100 of the floor brush 1 may include an upper housing 110 and a lower housing 120, which together enclose a receiving space, and the aforementioned motor and other components are received in the receiving space of the housing 100. The roller brush 200 may be detachably mounted on the front end of the housing 100, for example, the roller brush 200 may be limited and fixed by the upper housing 110 and the lower housing 120 together, so as to be mounted on the housing 100.

[0166] For example, the roller brush 200 may include a roller brush body 210 and a support frame 220. The roller brush body 210 is used to contact and roll along the surface to be cleaned to clean the surface to be cleaned. The support frame 220 is used to support and fix the roller brush body 210, and the support frame 220 is detachably connected to the housing 100 to install the roller brush body 210 on the housing 100.

[0167] Continue to see Figure 3 As shown, a sewage suction pipe 600 may also be provided in the housing 100 of the floor brush 1, and the sewage suction pipe 600 may be connected between the roller brush 200 and the sewage tank of the body. In other words, one end of the sewage suction pipe 600 extends to the roller brush 200, and the other end of the sewage suction pipe 600 is connected to the sewage tank. A negative pressure environment may be generated in the sewage suction pipe 600, so that the sewage on the surface to be cleaned (including foreign matter such as particles and hair) around the roller brush 200 enters the sewage tank through the sewage suction pipe 600 under the action of negative pressure, thereby completing the cleaning work.

[0168] Figure 4 A schematic diagram of the structure of a brush plate provided in an embodiment of the present application.

[0169] See also Figure 4 As shown, the brush plate 520 may include a base 521 and a cleaning portion 522, the base 521 may be connected to the mobile lifting mechanism 510, and the cleaning portion 522 may be detachably connected to the base 521. The cleaning portion 522 may be used to make frictional contact with the surface to be cleaned to achieve cleaning of the surface to be cleaned. The base 521 may be used to support the cleaning portion 522, so that the cleaning portion 522 may be installed on the mobile lifting mechanism 510 through the base 521.

[0170] The cleaning portion 522 may be provided with bristles 5221 , and when the brush plate 520 moves back and forth, the bristles 5221 may be in reciprocating frictional contact with the surface to be cleaned, so as to clean the stubborn stains on the surface to be cleaned.

[0171] For example, the bristles 5221 can be evenly distributed along the width and length of the brush plate 520, and cover the side of the brush plate 520 facing away from the movable lifting mechanism 510. In this way, during the reciprocating movement of the brush plate 520, each area passed by the brush plate 520 can always be under the friction of the bristles 5221, which can ensure the smooth operation of the brush plate 520 on the surface to be cleaned, and can effectively improve the cleaning efficiency of the brush plate 520.

[0172] Alternatively, the cleaning part 522 may also be a rag, which may cover the side of the brush plate 520 facing away from the movable lifting mechanism 510. The rag has good water absorption and can effectively absorb and wipe the water stains on the surface to be cleaned, thereby effectively reducing the watermark on the surface to be cleaned.

[0173] By making the cleaning part 522 detachably connected to the base 521, different cleaning parts 522 can be replaced according to the different types of stains to be cleaned on the surface to be cleaned. For example, when stubborn stains need to be cleaned, the cleaning part 522 with bristles 5221 can be installed on the base 521 so that the bristles 5221 can clean the stubborn stains on the surface to be cleaned. When water stains need to be cleaned, the cleaning part 522 with bristles 5221 can be removed and replaced with a rag-type cleaning part 522 to wipe and absorb the water stains. In this way, the flexibility of the brush plate 520 can be effectively improved, which helps to improve the diversity of the cleaning functions of the floor brush 1.

[0174] Figure 5 A cross-sectional view of a cleaning device provided in an embodiment of the present application at a cross section, Figure 6 for Figure 5 Magnified view of area A in the middle.

[0175] See also Figure 5 and Figure 6 As shown, a liquid outlet 130 may be provided on the housing 100 or the brush plate 520, and the liquid outlet 130 may be connected to the liquid supply assembly 700, and the cleaning liquid provided by the liquid supply assembly 700 may be sprayed out through the liquid outlet 130. When the floor brush 1 is moving, the cleaning liquid may be sprayed on the surface to be cleaned through the liquid outlet 130, so that the cleaning liquid may infiltrate the stains on the surface to be cleaned, so as to facilitate the brush plate 520 to remove the stains, and the cleaning efficiency and cleaning effect of the wiping plate may be effectively improved.

[0176] For example, in some examples, the liquid outlet 130 can be as follows Figure 6 As shown in FIG. 1 , the liquid outlet 130 is opened on the housing 100. For example, along the direction of travel of the floor brush 1, the liquid outlet 130 can be located in front of the brush plate 520. In other words, the liquid outlet 130 can be located between the brush plate 520 and the roller brush 200 (refer to FIG. 1 ). Figure 2 As the floor brush 1 moves, the cleaning liquid sprayed from the liquid outlet 130 can first soak the stain in front of the brush plate 520. When the brush plate 520 moves onto the stain, the stain has been soaked by the cleaning liquid, which makes it easier for the brush plate 520 to remove the stain.

[0177] Alternatively, the liquid outlet 130 may also be located behind the brush plate 520, that is, the brush plate 520 is located between the liquid outlet 130 and the roller brush 200. When the floor brush 1 cleans the surface to be cleaned, the floor brush 1 may move back and forth. The liquid outlet 130 may soak the stains at the rear end of the brush plate 520, and when the floor brush 1 moves backward, the brush plate 520 may remove the soaked stains, so as to improve the cleaning effect of the brush plate 520 on the stains.

[0178] Alternatively, in other examples, the liquid outlet 130 may be provided on the brush plate 520. For example, a cavity may be provided inside the brush plate 520, and the liquid outlet 130 may be connected to the cavity inside the brush plate 520. The cleaning liquid provided by the liquid supply assembly 700 may enter the cavity inside the brush plate 520, and then be sprayed outward through the liquid outlet 130 to wet the stains on the surface to be cleaned.

[0179] In the embodiment of the present application, the liquid outlet 130 is provided on the housing 100 as an example for description.

[0180] The number of the liquid outlet holes 130 can be multiple, which can increase the area occupied by the liquid outlet holes 130 on the housing 100, increase the amount of liquid discharged from the liquid outlet holes 130, and thus increase the flow rate of the cleaning liquid. The cleaning liquid can fully soak the stains on the surface to be cleaned, especially for some stains with strong adhesion, which can fully soften the stains, thereby improving the cleaning efficiency of the stains and enhancing the cleaning effect of the stains.

[0181] Among them, a plurality of liquid outlet holes 130 can be arranged at intervals along the length direction of the brush plate 520, and the liquid outlet holes 130 are distributed along the length direction of the brush plate 520. It can be understood that there are liquid outlet holes 130 on the corresponding length of the brush plate 520, and the liquid outlet holes 130 are evenly distributed. In this way, when the brush plate 520 moves back and forth, each area under the brush plate 520 can always be sprayed with the cleaning liquid sprayed from the liquid outlet holes 130, so that the cleaning liquid can infiltrate the stains in the area where the brush plate 520 passes, so that the brush plate 520 can clean, which can effectively improve the cleaning effect of the brush plate 520 on the stains.

[0182] In the embodiment of the present application, the liquid outlet 130 can extend obliquely toward the brush plate 520 from the end of the liquid outlet 130 away from the surface to be cleaned to the end of the liquid outlet 130 facing the surface to be cleaned. In this way, the liquid outlet 130 can guide the spraying direction of the cleaning liquid, and the cleaning liquid sprayed from the liquid outlet 130 can be sprayed toward the brush plate 520. The stains in the corresponding area below the brush plate 520 can be soaked so that the brush plate 520 can clean the stains, which can effectively improve the cleaning effect of the brush plate 520 on the stains.

[0183] Moreover, the cleaning liquid can also be sprayed toward the brush plate 520 under the guidance of the liquid outlet 130 to wet the brush plate 520. In this way, when the brush plate 520 cleans the surface to be cleaned, the cleaning liquid on the brush plate 520 can also soak the stains on the surface to be cleaned to reduce the adhesion of the stains, thereby improving the cleaning effect of the brush plate 520 on the stains.

[0184] In addition, the wet brush disc 520 can also reduce the friction between the brush disc 520 and the surface to be cleaned, which helps to reduce the wear of the brush disc 520 and increase the service life of the brush disc 520.

[0185] For example, the cross-sectional area of ​​the end of the liquid outlet 130 away from the surface to be cleaned is larger than the cross-sectional area of ​​the end of the liquid outlet 130 close to the surface to be cleaned. By narrowing the cross-sectional area of ​​the end of the liquid outlet 130 close to the surface to be cleaned, the pressure of the cleaning liquid sprayed from the liquid outlet 130 can be increased, the flow rate of the cleaning liquid can be increased, and the spray range of the cleaning liquid can be expanded, which helps to spray the cleaning liquid in the form of mist.

[0186] Such a configuration is conducive to the cleaning liquid to quickly penetrate into the stains, so as to fully and completely immerse the stains, thereby enabling the brush plate assembly 500 to quickly and completely remove the stains, improve the cleaning efficiency of the brush plate assembly 500, and enhance the cleaning effect of the brush plate assembly 500.

[0187] For example, the cross-sectional area of ​​the liquid outlet 130 may change gradually. In other words, the cross-sectional area of ​​the liquid outlet 130 may gradually decrease from the end of the liquid outlet 130 away from the surface to be cleaned to the end of the liquid outlet 130 facing the surface to be cleaned. This can avoid the liquid outlet 130 from having an obvious diameter change portion, can avoid stress concentration in the liquid outlet 130, prevent cracks or damage in the liquid outlet 130, and help ensure the service life of the floor brush 1.

[0188] Continue to see Figure 5 and Figure 6 As shown, the liquid supply assembly 700 may include a water pump 710 and a liquid supply pipe (not shown in the figure). The water pump 710 may be arranged in the housing 100 of the floor brush 1, or the water pump 710 may be arranged on the body. A liquid supply pipe is connected between the roller brush 200 and the water pump 710, and between the liquid outlet 130 and the water pump 710, and the liquid supply pipe is used for the cleaning liquid to flow through. The water pump 710 is used to provide pressure and increase the power of the cleaning liquid to transport the cleaning liquid to the roller brush 200 and the liquid outlet 130, so as to use the cleaning liquid to clean the surface to be cleaned.

[0189] In some embodiments, the cleaning liquid of the liquid outlet 130 and the cleaning liquid of the roller brush 200 can both come from the clean water tank on the body. In this case, the cleaning device can provide cleaning liquid to the roller brush 200 and the liquid outlet 130 at the same time through a water pump 710. For example, the water pump 710 can be arranged in the housing 100 of the floor brush 1, and two liquid supply pipes can be connected to the water pump 710, and the two liquid supply pipes can extend to the roller brush 200 and the liquid outlet 130 respectively. For example, the two liquid supply pipes can be a first liquid supply pipe (not shown in the figure) and a second liquid supply pipe (not shown in the figure), wherein the first liquid supply pipe can include a water inlet end (not shown in the figure) and a water outlet end (not shown in the figure), the water inlet end can be connected to the water pump 710, and the water outlet end can extend to the liquid outlet 130 and communicate with the liquid outlet 130, so that the water pump 710 can supply water to the liquid outlet 130 through the first liquid supply pipe. One end of the second liquid supply pipe is connected to the water pump 710, and the other end is set corresponding to the roller brush 200. For example, the second liquid supply pipe can also have a water inlet end and a water outlet end. The water inlet end of the second liquid supply pipe can be connected to the water pump 710, and the water outlet end can be set corresponding to the roller brush 200, so that the water pump 710 can supply water to the roller brush 200 through the second liquid supply pipe.

[0190] Alternatively, the cleaning device may also provide cleaning liquid to the roller brush 200 and the liquid outlet hole 130 respectively through two water pumps 710. For example, the two water pumps 710 may be both disposed in the housing 100 of the floor brush 1. Both water pumps 710 are connected to liquid supply pipes, and the liquid supply pipes connected to the two water pumps 710 extend to the roller brush 200 and the liquid outlet hole 130 respectively, so as to supply water to the roller brush 200 and the liquid outlet hole 130 respectively through the two water pumps 710.

[0191] Alternatively, the cleaning liquid in the liquid outlet 130 and the cleaning liquid in the roller brush 200 may also come from other liquid storage components. For example, a liquid storage component (not shown in the figure) may be provided in the shell 100 of the floor brush 1, and the liquid storage component may be used to provide cleaning liquid to the liquid supply component 700, so that the liquid supply component 700 can provide cleaning liquid to the liquid outlet 130 and the roller brush 200.

[0192] Continuing to refer to the figure, the floor brush 1 may further include a first water divider 720 and a second water divider (not shown in the figure), and the first water divider 720 and the second water divider may be located in the housing 100. The water outlet end of the first liquid supply pipe may be connected to the first water divider 720, and the first water divider 720 may be used to provide cleaning liquid to the liquid outlet hole 130. The other end of the second liquid supply pipe may be connected to the second water divider, and the second water divider may be used to provide cleaning liquid to the roller brush 200.

[0193] For example, the first water distributor 720 may have a first liquid storage chamber 721, which may be connected to the first liquid supply pipe and the liquid outlet 130 respectively, and the first liquid storage chamber 721 may contain cleaning liquid. The cleaning liquid pumped out by the water pump 710 may flow to the first liquid supply pipe, and flow to the first liquid storage chamber 721 in the first water distributor 720 through the first liquid supply pipe, and finally sprayed onto the surface to be cleaned through the liquid outlet 130 connected to the first liquid storage chamber 721.

[0194] Continue to see Figure 6 As shown, a water outlet 722 may be provided on the first water divider 720, and the water outlet 722 may be communicated with the first liquid storage chamber 721, wherein the number of the water outlets 722 may be the same as the number of the liquid outlet holes 130, and the water outlets 722 are respectively aligned with the liquid outlet holes 130. The cleaning liquid in the first water divider 720 may flow out through the water outlet 722 and the liquid outlet holes 130 in sequence, and sprayed onto the surface to be cleaned, so as to infiltrate the stains on the surface to be cleaned.

[0195] Correspondingly, the second water distributor may also have a second liquid storage chamber and a water outlet 722. Specifically, the specific structure of the liquid storage chamber and the water outlet 722 in the second water distributor may refer to the structure of the first water distributor 720, which will not be repeated here.

[0196] By providing a brush plate 520 on the floor scrubber and using a liquid supply assembly 700 to jointly provide liquid to the brush plate 520 and the roller brush 200, the cleaning ability of the floor scrubber can be further improved. When encountering stubborn stains, the roller brush 200 and the brush plate 520 can be used to clean multiple scenes and multiple stains. For example, when encountering stubborn stains, you can first use the brush plate 520 in conjunction with the spray liquid to wipe. After wiping, the stubborn stains on the ground will become ordinary stains. At this time, the roller brush 200 can be used to remove the above-mentioned ordinary stains. In this way, the above-mentioned cooperation can achieve the cleaning of stubborn stains, and at the same time, it can also remove ordinary stains after the stubborn stains are dissolved, and can also absorb the water sprayed from the wiping plate.

[0197] The method of using the above-mentioned liquid supply component 700 to supply liquid to both of them does not need to increase the volume of the floor brush 1, and the control method is simpler. Only one liquid supply component 700 needs to be controlled, which reduces the operation difficulty and cost.

[0198] In the embodiment of the present application, a control component (not shown in the figure) may also be provided in the shell 100 of the floor brush 1. For example, the control component may be a circuit board provided in the shell 100. The control component may be used to control the operation of the brush plate assembly 500 and the liquid supply assembly 700. The moving lifting mechanism 510 of the brush plate assembly 500 may be electrically connected to the control component (for example, through a wire), and the water pump 710 of the liquid supply assembly 700 may also be electrically connected to the control component (for example, through a wire).

[0199] When the brush plate assembly 500 is required to clean the stains on the surface to be cleaned, the control component can control the movable lifting mechanism 510 to operate, so that the movable lifting mechanism 510 drives the brush plate 520 to descend to the working position and reciprocate.

[0200] At the same time, the control unit controls the water pump 710 to start, so as to deliver the cleaning liquid to the first water distributor 720 through the water pump 710, so that the first water distributor 720 sprays the cleaning liquid to the surface to be cleaned through the liquid outlet 130. When the stains on the surface to be cleaned are cleaned, the control unit controls the mobile lifting mechanism 510 to drive the brush plate 520 to rise to the retracted position. At the same time, the control unit controls the water pump 710 to stop delivering the cleaning liquid to the first water distributor 720.

[0201] In some embodiments, the brush plate assembly 500 can be manually controlled by the user to work. For example, the housing 100 or the body of the floor brush 1 is provided with an operating member (not shown in the figure), for example, the operating member can be a touch key, a pressing member or a toggle member, and the operating member is electrically connected to the control member. The user manipulates the operating member to send a control signal to the control member to control the movement and lifting mechanism 510 and the liquid supply assembly 700 of the brush plate assembly 500 to work.

[0202] When the user recognizes that there is a (stubborn) stain on the surface to be cleaned, the cleaning device is moved to the stain so that the brush plate assembly 500 is directly above the stain. Then, the user manipulates the operating member to send a control signal to the control member, and the control member controls the brush plate assembly 500 and the liquid supply assembly 700 to operate. When the user recognizes that the stain is removed, the user manipulates the operating member again to release the control signal of the control member, and the brush plate assembly 500 and the liquid supply assembly 700 stop operating.

[0203] In other embodiments, the floor brush 1 is also provided with a detection member (not shown in the figure), which is used to identify stains on the surface to be cleaned. For example, the detection member is used to identify stubborn stains on the surface to be cleaned, and the detection member is electrically connected to the moving lifting mechanism 510 of the brush plate assembly 500 and the liquid supply assembly 700.

[0204] When the detection part identifies the stain, the moving lifting mechanism 510 and the liquid supply assembly 700 are started, and the moving lifting mechanism 510 drives the brush plate 520 to descend to the working position and reciprocate. The liquid supply assembly 700 provides cleaning liquid to the brush plate 520, so that the stain on the surface to be cleaned is cleaned by the brush plate 520 and the cleaning liquid. When the detection part identifies that the stain on the surface to be cleaned is removed, the brush plate assembly 500 and the liquid supply assembly 700 are closed, the moving lifting mechanism 510 drives the brush plate 520 to rise to the stowed position, and the liquid supply assembly 700 stops providing cleaning liquid to the brush plate 520.

[0205] By configuring the detection member on the floor brush 1, the detection member can automatically identify the stains on the surface to be cleaned, and then the brush plate assembly 500 can be automatically controlled, without manual operation to start and close the brush plate assembly 500 and the liquid supply assembly 700. In this way, the control of the brush plate assembly 500 and the liquid supply assembly 700 is more automated and intelligent, which can reduce the user's operating difficulty and improve the control performance of the cleaning equipment.

[0206] The detection component can be electrically connected to the control component, for example, the detection component and the control component can be connected via wireless communication or wired connection via a circuit board or a wire. The detection component sends a control signal to the control component, and the control component controls the start or shut down of the mobile lifting mechanism 510 and the liquid supply component 700 according to the control signal sent by the detection component.

[0207] When the detection component identifies that there are stains on the surface to be cleaned, the detection component sends a control signal to the control component to start the brush plate assembly 500 and the liquid supply assembly 700, and the control component controls the brush plate assembly 500 and the liquid supply assembly 700 to start. The mobile lifting mechanism 510 drives the brush plate 520 to descend to the working position, and at the same time, the liquid supply assembly 700 provides cleaning liquid to the brush plate 520.

[0208] When the detection component recognizes that the stain on the surface to be cleaned is removed, the detection component sends a control signal to the control component to close the brush plate assembly 500 and the liquid supply assembly 700, and the control component controls the brush plate assembly 500 and the liquid supply assembly 700 to close. The mobile lifting mechanism 510 drives the brush plate 520 to rise to the stowed position, and at the same time, the liquid supply assembly 700 stops supplying cleaning liquid to the brush plate 520.

[0209] The detection member can be arranged on the brush plate 520, for example, the detection member can be arranged in the central area of ​​the brush plate 520. In this way, the detection range of the detection member corresponds to the coverage range of the brush plate 520, and the operation of the brush plate assembly 500 can be accurately controlled so that the brush plate 520 falls exactly on the stains on the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the brush plate assembly 500.

[0210] Of course, in the case where the position on the brush plate 520 is limited or the installation is difficult, the detection member can also be set on the housing 100 of the floor brush 1. By calculating the relationship between the detection range of the detection member and the coverage range of the brush plate 520, it is ensured that the brush plate 520 is accurately positioned above the stain. For example, the detection member can be located on the side wall portion of the housing 100 that is arranged around the outer periphery of the brush plate 520. In this way, the detection member is close to the brush plate 520, and the overlap rate between the detection range of the detection member and the coverage range of the brush plate 520 is high, which facilitates the positioning of the brush plate 520 above the stain.

[0211] Exemplarily, the detection element may be an infrared sensor, which identifies information such as the thickness and area of ​​the stain, thereby determining whether the stain is a stubborn stain, and controlling the start and stop of the brush plate assembly 500 and the liquid supply assembly 700.

[0212] Alternatively, the detection member may also be a camera, which identifies the shape, properties, area and other information of the stain, thereby determining whether the stain is a stubborn stain, and controlling the start and stop of the brush plate assembly 500 and the liquid supply assembly 700.

[0213] Alternatively, the detection member may include an infrared sensor and a camera, which can be used to jointly identify stains, determine whether the stains are stubborn stains, and control the start and stop of the brush plate assembly 500 and the liquid supply assembly 700. In this way, the detection accuracy of the detection member can be improved, and the operation of the brush plate assembly 500 and the liquid supply assembly 700 can be controlled more accurately.

[0214] Figure 7 A structural schematic diagram of a mobile lifting mechanism provided in an embodiment of the present application is shown in FIG. Figure 8 A cross-sectional view of a mobile lifting mechanism provided in an embodiment of the present application.

[0215] See also Figure 7 and Figure 8As shown, the mobile lifting mechanism 510 of the brush plate assembly 500 may include a first driving structure 511, a rotating member 512 and a lifting rotating member 513, wherein the rotating member 512 is connected to the first driving structure 511, and the lifting rotating member 513 is connected to the rotating member 512 by transmission. The brush plate 520 is connected to the lifting rotating member 513, for example, the brush plate 520 may be connected to the bottom end of the lifting rotating member 513. The first driving structure 511 is used to drive the rotating member 512 to rotate, for example, the first driving structure 511 may drive the rotating member 512 to rotate in a first direction or a second direction, and the first direction and the second direction are two opposite rotation directions. When the first driving structure 511 drives the rotating member 512 to rotate in the first direction, the lifting rotating member 513 may first descend to a specified position and then be driven to rotate by the rotating member 512. When the lifting rotating member 513 descends, it may drive the brush plate 520 to descend synchronously. When the brush plate 520 descends to the working position in contact with the surface to be cleaned, the lifting and rotating member 513 rotates and drives the brush plate 520 to move back and forth, so that the brush plate 520 cleans the surface to be cleaned.

[0216] When the first driving structure 511 drives the rotating member 512 to rotate in the second direction, the lifting rotating member 513 rises, and drives the brush plate 520 to rise synchronously. When the brush plate 520 rises to the stowed position, the mobile lifting mechanism 510 stops working.

[0217] Continue to see Figure 7 and Figure 8 As shown, the mobile lifting mechanism 510 may further include a first eccentric wheel 514, which may be connected to the lifting rotating member 513, for example, may be connected to the bottom end of the lifting moving member. The first eccentric wheel 514 is also movably connected to the brush plate 520. When the lifting rotating member 513 rotates, the first eccentric wheel 514 may be driven to rotate, and the first eccentric wheel 514 may drive the brush plate 520 to reciprocate.

[0218] For example, the edge of the first eccentric wheel 514 can abut against the brush disc 520. When the lifting and rotating member 513 drives the first eccentric wheel 514 to rotate, the position abutting against the brush disc 520 also changes with the rotation of the first eccentric wheel 514. Accordingly, the distance between the abutting position of the brush disc 520 and the center of the first eccentric wheel 514 is also different, thereby driving the brush disc 520 to reciprocate, thereby cleaning the surface to be cleaned.

[0219] The first eccentric wheel 514 can convert the rotational motion of the lifting and rotating part 513 into the reciprocating motion of the brush disc 520, so that the brush disc 520 can make frictional contact with the surface to be cleaned to achieve cleaning of stubborn stains on the surface to be cleaned, which can effectively improve the cleaning effect and cleaning efficiency of the brush disc 520 on stubborn stains.

[0220] Moreover, the eccentric wheel has a simple structure, a small size and reliable transmission. By using the first eccentric wheel to convert the rotational motion of the lifting and rotating member 513 into the reciprocating motion of the brush plate 520, the overall structure of the brush plate assembly 500 can be made more compact. It should be understood that the floor brush 1 assembly is a complex whole with multiple components inside. If it is driven by other means, the space it occupies in the floor brush 1 is larger, and there is a high probability that there is no corresponding installation space in the floor brush 1, or the overall structure of the floor brush 1 will become larger, resulting in a poor user experience.

[0221] Continue to see Figure 7 and Figure 8 As shown, the first driving structure 511 may include a first driving motor 5111, a transmission assembly 5112 and a driving shaft 5113. The transmission assembly 5112 is in driving connection with the first driving motor 5111, the driving shaft 5113 is connected with the transmission assembly 5112, and the rotating member 512 is connected with the driving shaft 5113. The first driving motor 5111 is used to generate a driving torque, which is transmitted to the driving shaft 5113 through the transmission assembly 5112. The driving shaft 5113 rotates, driving the rotating member 512 to rotate.

[0222] Among them, the first driving motor 5111 has a relatively large rotation speed and a relatively small torque. By setting a transmission component 5112 between the first driving motor 5111 and the driving shaft 5113, the transmission component 5112 can play a role in reducing speed and increasing torque, so as to transmit a suitable rotation speed and torque to the driving shaft 5113, thereby ensuring stable operation of the brush plate 520.

[0223] Continue to see Figure 7 and Figure 8 As shown, in this embodiment, the output end of the first drive motor 5111 may be provided with a worm 51111, and the transmission assembly 5112 includes a gear set, and the worm 51111 cooperates with the gear set to reduce speed and increase torque, and transmit appropriate speed and torque to the drive shaft 5113. The gear set may include a transmission gear 51121 and an output gear 51122, the transmission gear 51121 meshes with the worm 51111, the output gear 51122 meshes with the transmission gear 51121, and the output gear 51122 is sleeved outside the drive shaft 5113. By designing the transmission ratio between the transmission gear 51121 and the output gear 51122, the speed and torque of the output gear 51122 are controlled within a suitable range.

[0224] For example, the transmission gear 51121 may include a first gear 51121a and a second gear 51121b, the first gear 51121a and the second gear 51121b are coaxially arranged, the first gear 51121a is meshed with the worm 51111 on the first driving motor 5111, and the second gear 51121b is meshed with the output gear 51122. The diameter of the first gear 51121a may be greater than the diameter of the second gear 51121b, the diameter of the output gear 51122 may be greater than the diameter of the first gear 51121a, and the first gear 51121a and the worm are meshed with each other.

[0225] The combination of 51111 can limit the rotation speed of the second gear 51121b. The transmission ratio between the output gear 51122 and the second gear 51121b is relatively large, which can reduce the rotation speed of the output gear 51122 and increase the torque of the output gear 51122.

[0226] Fig. 9 An exploded view of a mobile lifting mechanism provided in an embodiment of the present application.

[0227] See also Figure 8 and Fig. 9 As shown, in order to enable the rotating member 512 to drive the lifting rotating member 513 to lift and rotate, the rotating member 512 and the lifting rotating member 513 can be cylindrical structures arranged inside and outside. In this way, the rotating member 512 and the lifting rotating member 513 can move relative to each other in the axial direction, and the lifting rotating member 513 can be lifted and lowered relative to the rotating member 512. In addition, the rotating member 512 and the lifting rotating member 513 can move relative to each other in the circumferential direction, and the relative rotation between the rotating member 512 and the lifting rotating member 513 can be achieved.

[0228] A spiral groove 5101 extending spirally and continuously may be provided on one of the peripheral wall (the side wall in the circumferential direction) of the rotating member 512 and the peripheral wall of the lifting rotating member 513 (see Fig.10 ), and the other may be provided with a spiral slider 5102 (see Fig.11 As shown in FIG. 5 , the size of the spiral slider 5102 matches the size of the spiral chute 5101. When the rotating member 512 and the lifting rotating member 513 are connected in cooperation, the spiral slider 5102 extends into the spiral chute 5101, or in other words, the spiral slider 5102 is slidably connected to the spiral chute 5101 (see FIG. 5 ). Figure 8 shown).

[0229] During the operation of the brush plate assembly 500 , the first driving structure 511 drives the rotating member 512 to rotate, so that the spiral slider 5102 slides along the extension direction of the spiral slide groove 5101 , thereby enabling the rotating member 512 to drive the lifting rotating member 513 to rotate and lift.

[0230] When the first driving structure 511 drives the rotating member 512 to rotate in the first direction, the spiral slider 5102 slides along the spiral slide groove 5101, so that the distance between the bottom end of the lifting rotating member 513 and the bottom end of the rotating member 512 gradually increases, and the lifting rotating member 513 gradually descends until the brush plate 520 at the bottom end of the lifting rotating member 513 descends to the working position in contact with the surface to be cleaned. The lifting rotating member 513 stops lifting and the rotating member 512 continues to rotate. At this time, the lifting rotating member 513 rotates under the drive of the rotating member 512 and drives the brush plate 520 to reciprocate.

[0231] For example, a limiting structure may be provided on the housing 100. When the rotating member 512 starts to rotate, the limiting structure may limit the lifting rotating member 513 to prevent the lifting rotating member 513 from rotating, thereby allowing the lifting rotating member 513 to be lifted. When the lifting rotating member 513 descends to a specified position, the spiral slider 5102 slides to the end of the spiral slide groove 5101, and the lifting rotating member 513 no longer descends, but rotates with the rotating member 512, thereby driving the brush plate 520 to reciprocate.

[0232] When the first driving structure 511 drives the rotating member 512 to rotate in the second direction, the spiral slider 5102 slides in the opposite direction in the spiral groove 5101, so that the distance between the bottom end of the lifting member and the bottom end of the rotating member 512 gradually decreases, and the lifting member gradually rises until the brush plate 520 at the bottom end of the lifting member rises to the retracted position.

[0233] When designing the rotating member 512 and the lifting rotating member 513, the sliding range of the spiral slider 5102 can be limited according to the working position and the stowed position of the brush plate 520. For example, see Figure 8 As shown, a first stopper 5103 may be provided on the spiral chute 5101, and the first stopper 5103 is used to limit the maximum position of the lifting and rotating member 513 relative to the rotating member 512, and the maximum position may correspond to the working position of the brush plate 520. That is, when the rotating member 512 rotates along the first direction, the spiral slider 5102 slides along the spiral chute 5101 until it abuts against the first stopper 5103, and the lifting and rotating member 513 descends to the lowest position. At this time, the brush plate 520 is just in the working position in contact with the surface to be cleaned.

[0234] Of course, the first stopper 5103 may not be provided on the spiral chute 5101. When the lifting rotating member 513 drives the brush plate 520 to descend to the working position, the spiral slider 5102 is not blocked from continuing to slide along the spiral chute 5101, or in other words, the spiral slider 5102 has a tendency to continue to slide along the spiral chute 5101. However, since the brush plate 520 has contacted the surface to be cleaned, the spiral slider 5102 is limited to the current height position. At this time, under the rotation of the rotating member 512, the lifting rotating member 513 rotates accordingly and drives the brush plate 520 to reciprocate to clean the surface to be cleaned.

[0235] A second stopper (not shown in the figure) may also be provided on the spiral chute 5101, and the second stopper is used to limit the maximum position of the lifting rotating member 513 relative to the rotating member 512, and the maximum position may correspond to the stowed position of the brush plate 520. That is, when the rotating member 512 rotates in the second direction, the spiral slider 5102 slides along the spiral chute 5101 until it abuts against the second stopper, and the lifting rotating member 513 rises to the highest position. At this time, the brush plate 520 is in the stowed position.

[0236] Of course, the second stopper may not be provided on the spiral slide groove 5101, but the bottom of the rotating member 512 may abut against the bottom of the lifting rotating member 513 to limit the highest position of the lifting rotating member 513. In other words, when the lifting rotating member 513 rises to the point where its bottom abuts against the bottom of the rotating member 512, the brush plate 520 is in the retracted position.

[0237] Exemplarily, when the spiral chute 5101 has a first stopper 5103 and a second stopper, the end walls at both ends of the spiral chute 5101 can be used as the first stopper 5103 and the second stopper, respectively. Taking the case where the spiral slider 5102 is arranged on the peripheral wall of the rotating member 512 and the spiral chute 5101 is arranged on the peripheral wall of the lifting rotating member 513 as an example, the end wall at the top of the spiral chute 5101 can be used as the first stopper 5103, and when the spiral slider 5102 slides along the spiral chute 5101 until it abuts against the end wall at the top of the spiral chute 5101, the lifting rotating member 513 descends to the lowest position. The end wall at the bottom of the spiral chute 5101 can be used as the second stopper, and when the spiral slider 5102 slides along the spiral chute 5101 until it abuts against the end wall at the bottom of the spiral chute 5101, the lifting rotating member 513 rises to the highest position.

[0238] Continue to see Figure 8 and Fig. 9As shown, on the basis of the cooperation between the rotating member 512 and the lifting rotating member 513, the brush plate assembly 500 may also include a guide sleeve 530, which is fixed in the housing 100 of the floor brush 1, and the rotating member 512 and the lifting rotating member 513 are both located in the guide sleeve 530. Through the guiding effect of the guide sleeve 530, the lifting trajectory of the lifting rotating member 513 is limited to ensure that the lifting rotating member 513 is lifted vertically. At the same time, the rotation trajectory of the lifting rotating member 513 is also limited to prevent the lifting rotating member 513 from shaking or deflecting. As a result, the brush plate 520 connected to the bottom end of the lifting rotating member 513 can stably contact the surface to be cleaned, ensuring that the brush plate 520 cleans the stains thoroughly and prevents scratching the surface to be cleaned or damaging the brush plate 520.

[0239] Continue to see Figure 8 and Fig. 9 As shown, the floor brush 1 may further include a stopper 540, which may be connected to the housing 100. For example, the stopper 540 may be fixedly connected to the guide sleeve 530 in the housing 100. The stopper 540 may be arranged around the outer periphery of the lifting and rotating member 513, and the stopper 540 and the lifting and rotating member 513 are frictionally matched. The stopper 540 may be used to limit the rotation of the lifting and rotating member 513 when the lifting and rotating member 513 is lifted or lowered.

[0240] For example, during the rotation of the rotating member 512, the rotating member 512 and the lifting rotating member 513 are screwed together, which will generate a screw driving force on the lifting rotating member 513. At this time, the friction clamping force generated by the limiter 540 on the lifting rotating member 513 will prevent the lifting rotating member 513 from rotating, so that the lifting rotating member 513 is lifted and lowered under the screw force, so as to drive the brush plate 520 to descend to the working position or rise to the stowed position.

[0241] For example, the inner wall of the limiter 540 may have a friction feeler 541, and the friction feeler 541 may be used to limit the rotation of the lifting and rotating member 513. For example, the number of friction feelers 541 may be multiple, and the multiple friction feelers 541 may be distributed between the outer wall of the lifting and rotating member 513 and the inner wall of the limiter 540, and the friction feelers 541 may be in a compressed state. The friction feelers 541 in a compressed state will generate an elastic clamping force to clamp the lifting and rotating member 513, which can increase the clamping force of the limiter 540 on the lifting and rotating member 513, and can effectively prevent the lifting and rotating member 513 from rotating, so that the lifting and rotating member 513 can be lifted and lowered.

[0242] Fig.10 A schematic diagram of the structure of a rotating member provided in an embodiment of the present application, Fig.11 A schematic diagram of the structure of a lifting and rotating member provided in an embodiment of the present application.

[0243] On one of the rotating member 512 and the lifting rotating member 513 , the spiral slider 5102 may be provided. The number of the spiral slider 5102 may be at least two, and the spiral slider 5102 may be arranged at intervals along the circumference of the rotating member 512 or the lifting rotating member 513 .

[0244] See also Fig.11 As shown in the figure, the spiral slider 5102 is arranged on the peripheral wall of the rotating member 512, and the spiral slider 5102 is arranged at intervals along the circumference of the rotating member 512. In this way, different spiral sliders 5102 contact different parts of the spiral chute 5101 in the circumferential direction, which can ensure the reliability of the connection between the lifting and rotating member 513 and the rotating member 512, and ensure the smooth movement of the lifting and rotating member 513 relative to the rotating member 512. In addition, since the spiral sliders 5102 are arranged at intervals along the circumferential direction, the total contact area between all the spiral sliders 5102 and the spiral chute 5101 is small, and the friction resistance between the lifting and rotating member 513 and the rotating member 512 is small, which can ensure the smooth movement of the lifting and rotating member 513 relative to the rotating member 512.

[0245] For example, the spiral sliders 5102 may be evenly spaced along the circumference of the rotating member 512 or the lifting rotating member 513 to ensure force balance between the lifting rotating member 513 and the rotating member 512, thereby improving the stability and reliability of the movement of the lifting rotating member 513. For example, three, four, five or more spiral sliders 5102 may be evenly spaced along the circumference on the peripheral wall of the rotating member 512 or the lifting rotating member 513.

[0246] As shown in the figure, as an example, the spiral slider 5102 matched with the spiral chute 5101 can also be extended in a spiral. In this way, the spiral slider 5102 and the spiral chute 5101 are in a surface contact mode, and the spiral slider 5102 and the spiral chute 5101 have a sufficient contact area, which can improve the reliability of the connection between the rotating member 512 and the lifting rotating member 513, and improve the stability of the movement of the lifting rotating member 513.

[0247] It should be noted that in the axial direction of the rotating member 512 or the lifting rotating member 513, the spiral slide 5101 includes a plurality of circles of slideways arranged in sequence. When each spiral slider 5102 extends along the spiral, for each spiral slider 5102 arranged at intervals along the circumference of the rotating member 512 or the lifting rotating member 513, different spiral sliders 5102 are located in different slideways of the spiral slide 5101 in the axial direction. In this way, the cooperation between the spiral slider 5102 and the spiral slide 5101 is more stable and reliable, and the lifting rotating member 513 moves more smoothly relative to the rotating member 512, which can improve the reliability of the brush plate assembly 500.

[0248] See also Fig.10 and Fig.11As shown, on the basis of designing the rotating member 512 and the lifting rotating member 513 as cylindrical structures arranged inside and outside, one of the rotating member 512 and the lifting rotating member 513 may include a rotating cylinder 5121, and the other may include an inner cylinder portion 5131 and an outer cylinder portion 5132 arranged inside and outside, the inner cylinder portion 5131 and the outer cylinder portion 5132 are connected to each other, and a matching space 5133 is formed between the inner cylinder portion 5131 and the outer cylinder portion 5132, and the rotating cylinder 5121 is inserted in the matching space 5133.

[0249] Taking the example of the rotating part 512 including the rotating cylinder 5121 and the lifting rotating part 513 including the inner cylinder portion 5131 and the outer cylinder portion 5132 arranged inside and outside, the bottom ends of the inner cylinder portion 5131 and the outer cylinder portion 5132 of the lifting rotating part 513 can be connected to each other, and the inner cylinder portion 5131 and the outer cylinder portion 5132 together form a matching space 5133 with an opening facing upward, and the rotating cylinder 5121 of the rotating part 512 is inserted into the matching space 5133 of the lifting rotating part 513.

[0250] With such a configuration, the annular matching space 5133 formed between the inner cylinder 5131 and the outer cylinder 5132 can guide and limit the moving trajectory of the rotating cylinder 5121. In addition, the movement trajectory of the lifting and rotating member 513 can be made more precise, the risk of shaking or deflection of the brush disc 520 can be reduced or even eliminated, the stability of the brush disc 520 rotating on the surface to be cleaned can be improved, and the surface to be cleaned or the brush disc 520 can be prevented from being scratched or damaged.

[0251] Among them, one of the spiral slide groove 5101 and the spiral slider 5102 is arranged on the peripheral wall of the rotating cylinder 5121, and the other is arranged on the outer peripheral wall of the inner cylinder 5131 or the inner peripheral wall of the outer cylinder 5132. Taking the spiral slider 5102 arranged on the rotating cylinder 5121 and the spiral slide groove 5101 arranged on the inner cylinder 5131 or the outer cylinder 5132 as an example, the spiral slider 5102 can be arranged on the outer peripheral wall of the rotating cylinder 5121, and correspondingly, the spiral slide groove 5101 can be arranged on the inner peripheral wall of the outer cylinder 5132. In this way, it is convenient to form the spiral slider 5102 on the rotating cylinder 5121, and it is convenient to assemble the lifting rotating member 513 and the rotating member 512.

[0252] Fig.12 A cross-sectional view of a cleaning device provided in an embodiment of the present application under another cross-section, Fig.13 for Fig.12 Magnified view of area B in the middle.

[0253] See also Fig.12 and Fig.13As shown, the floor brush 1 may further include an auxiliary lifting mechanism 800, the brush plate 520 is further connected to the auxiliary lifting mechanism 800, the mobile lifting mechanism 510 and the auxiliary lifting mechanism 800 may be respectively connected to opposite ends of the brush plate 520, and the auxiliary lifting mechanism 800 may be used to assist the mobile lifting mechanism 510 in driving the brush plate 520 to move up and down. For example, the mobile lifting mechanism 510 and the auxiliary lifting mechanism 800 may respectively drive the brush plate 520 to move up and down from both ends of the brush plate 520. In this way, the uniformity of the force on the brush plate 520 may be improved, and the tilting of the brush plate 520 during the lifting process may be reduced or avoided, which is conducive to improving the stability and reliability of the lifting of the brush plate 520.

[0254] Continue to see Fig.13 As shown, the auxiliary lifting mechanism 800 may include a second driving structure 810, a second eccentric wheel 820 and a lifting assembly 830, wherein the second eccentric wheel 820 is connected to the second driving structure 810, the lifting assembly 830 is in contact with the outer edge of the second eccentric wheel 820, and the lifting assembly 830 is connected to the brush plate 520. The second driving structure 810 drives the second eccentric wheel 820 to rotate, and the second eccentric wheel 820 drives the lifting assembly 830 to rise and fall, and the lifting assembly 830 can drive the brush plate 520 to rise and fall.

[0255] The second driving structure 810 can be configured to drive the second eccentric wheel 820 to rotate in two opposite directions, namely, the third direction or the fourth direction. When the second driving structure 810 drives the second eccentric wheel 820 to rotate in the third direction, the second eccentric wheel 820 can drive the lifting assembly 830 to descend, so that the lifting assembly 830 drives the brush plate 520 to descend. When the second driving structure 810 drives the second eccentric wheel 820 to rotate in the fourth direction, the second eccentric wheel 820 can drive the lifting assembly 830 to ascend, so that the lifting assembly 830 drives the brush plate 520 to ascend.

[0256] For example, when the mobile lifting mechanism 510 needs to drive the brush plate 520 to descend, the second driving structure 810 in the auxiliary lifting mechanism 800 can drive the second eccentric wheel 820 to rotate along the third direction, so that the second eccentric wheel 820 can drive the brush plate 520 to descend synchronously through the lifting assembly 830. Correspondingly, when the mobile lifting mechanism 510 needs to drive the brush plate 520 to ascend, the second driving structure 810 in the auxiliary lifting mechanism 800 can drive the second eccentric wheel 820 to rotate along the fourth direction, so that the second eccentric wheel 820 can drive the brush plate 520 to ascend synchronously through the lifting assembly 830.

[0257] Continue to see Fig.13As shown, the lifting assembly 830 may include a first guide rod 831 and a support plate 832. The first guide rod 831 may extend along the lifting direction of the brush disc 520 and slide with the housing 100. One end of the first guide rod 831 may be connected to the brush disc 520, and the other end may be connected to the support plate 832. The support plate 832 may abut against the second eccentric wheel 820. In the process of the second driving structure 810 driving the second eccentric wheel 820 to rotate, the support plate 832 may always abut against the second eccentric wheel 820 under the action of gravity. As the second eccentric wheel rotates, the height of the support rod may change. The support plate 832 may drive the first guide rod 831 to lift relative to the housing 100, so that the first guide rod 831 drives the brush disc 520 to lift.

[0258] The first guide rod can play a guiding role so that the brush plate 520 can be smoothly lifted and lowered along the first guide rod 831, which can reduce or avoid the brush plate 520 from tilting or deflecting during the lifting process, and help improve the lifting and lowering stability of the brush plate 520.

[0259] Continue to see Fig.13 As shown, the housing 100 may further include a first guide structure 840, and the first guide rod 831 may be inserted into the first guide structure 840 and slideably cooperate with the first guide structure 840. For example, the first guide structure 840 may include a first guide enclosure 841 and a first guide member 842, the first guide enclosure 841 may be connected to the housing 100, the first guide rod 831 may be inserted into the first guide member 842 and slideably cooperate with the first guide member 842. One of the first guide enclosure 841 and the first guide member 842 has a first slide groove 8401, and the other has a first slider 8402, the first slider 8402 is slidably connected to the first slide groove 8401, and the sliding track of the first guide member 842 is the same as the reciprocating movement track of the brush plate 520.

[0260] During the reciprocating movement of the brush plate 520, the first guide member 842 and the first guide enclosure 841 can slide relative to each other through the cooperation between the first slider 8402 and the first slide groove 8401, so that the first guide member 842 can slide reciprocally synchronously with the brush plate 520, which helps to improve the reliability and stability of the reciprocating movement of the brush plate 520.

[0261] For example, see Fig.13As shown, the first slide groove 8401 may be located on the inner wall of the first guide enclosure 841, and the first slider 8402 may be located on the outer periphery of the first guide member 842. During the reciprocating movement of the brush plate 520, the brush plate 520 may drive the first guide member 842 to reciprocate synchronously through the first guide rod 831, and the first slider 8402 on the first guide member 842 may slide in the first slide groove 8401. This can effectively reduce or avoid the occurrence of jamming of the brush plate 520 during the reciprocating movement, and help improve the stability of the reciprocating movement of the brush plate 520.

[0262] Continue to see Fig.13 As shown, the floor brush 1 may further include a first elastic member 850, and the first elastic member 850 may abut between the first guide structure 840 and the brush disc 520. For example, the first elastic member 850 may be an elastic member such as a spring, a spring sheet or an elastic glue. One end of the first elastic member 850 may abut against the first guide member 842 in the first guide structure 840, and the other end may abut against the brush disc 520, and the first elastic member 850 may be in a compressed state. Since the first elastic member 850 is in a compressed state, the elastic force generated by the first elastic member 850 acts on the brush disc 520, so that the brush disc 520 can be in close contact with the surface to be cleaned, thereby ensuring the cleaning effect of the brush disc 520 on the surface to be cleaned.

[0263] Fig.14 for Fig.12 Magnified view of area C in the middle.

[0264] See also Fig.12 and Fig.14 As shown, the floor brush 1 may further include an auxiliary guide mechanism 900, which may include a second guide rod 920 and a second guide structure 910. The second guide structure 910 is located on the housing 100, and the second guide rod 920 may be connected to the brush plate 520, and the second guide rod 920 and the second guide structure 910 are slidably matched. The auxiliary guide mechanism 900 and the auxiliary lifting mechanism 800 may be respectively located at opposite ends of the brush plate 520. The second guide rod 920 may be parallel to the first guide rod 831. During the lifting and lowering process of the brush plate 520, the second guide rod 920 may also provide guidance for the lifting and lowering of the brush plate 520, so that the lifting and lowering of the brush plate 520 is more stable and reliable.

[0265] The second guide structure 910 may include a second guide enclosure 911 and a second guide member 912. The second guide enclosure 911 may be connected to the housing 100. The second guide rod 920 may be inserted into the second guide member 912 and slidably cooperate with the second guide member 912. One of the second guide enclosure 911 and the second guide member 912 has a second slide groove 913, and the other has a second slider 914. The second slider 914 is slidably connected to the second slide groove 913, and the sliding track of the second guide member 912 is the same as the reciprocating movement track of the brush plate 520.

[0266] During the reciprocating movement of the brush plate 520, the second guide member 912 and the second guide enclosure 911 can slide relative to each other through the cooperation between the second slider 914 and the second slide groove 913, so that the second guide member 912 can slide reciprocally synchronously with the brush plate 520, which helps to improve the reliability and stability of the reciprocating movement of the brush plate 520.

[0267] For example, see Fig.14 As shown, the second chute 913 may be located on the inner wall of the second guide enclosure 911, and the second slider 914 may be located on the outer periphery of the second guide member 912. During the reciprocating movement of the brush plate 520, the brush plate 520 may drive the second guide member 912 to reciprocate synchronously through the second guide rod 920, and the second slider 914 on the second guide member 912 may slide in the second chute 913. This can effectively reduce or avoid the occurrence of jamming of the brush plate 520 during the reciprocating movement, and help improve the stability of the reciprocating movement of the brush plate 520.

[0268] Continue to see Fig.14 As shown, a second elastic member 930 may also be provided between the second guide structure 910 and the brush plate 520. One end of the second elastic member 930 may abut against the second guide member 912 in the second guide structure 910, and the other end may abut against the brush plate 520, and the second elastic member 930 may be in a compressed state. Since the second elastic member 930 is in a compressed state, the elastic force generated by the second elastic member 930 may act on the brush plate 520, so that the brush plate 520 may be in close contact with the surface to be cleaned, thereby ensuring the cleaning effect of the brush plate 520 on the surface to be cleaned.

[0269] In addition, the second elastic member 930 and the first elastic member 850 are respectively pressed against the brush plate 520 at both ends of the brush plate 520, which helps to improve the uniformity of the force applied to the brush plate 520, enables the brush plate 520 to contact the surface to be cleaned more evenly, and helps to improve the cleaning effect of the brush plate 520 on the surface to be cleaned.

[0270] Fig.15 A schematic diagram of the structure of a cleaning system provided in an embodiment of the present application is shown in FIG. Fig.16An exploded view of a cleaning system provided in an embodiment of the present application, Fig.17 A schematic diagram of the structure of a base station provided in an embodiment of the present application.

[0271] The present application also provides a cleaning system 10, see Fig.15 and Fig.16 As shown, the cleaning system 10 may include a base station 2 and a cleaning device in any of the above scenarios. The base station 2 may be used to store the cleaning device. For example, when the cleaning device finishes cleaning work, the cleaning device may be placed on the base station 2. The base station 2 may charge and clean the cleaning device to maintain the cleaning device.

[0272] By making the cleaning system 10 include the above-mentioned cleaning equipment, the cleaning effect and cleaning efficiency of the cleaning system 10 can be effectively improved, and the comprehensive performance of the cleaning system 10 can be improved.

[0273] See also Fig.16 As shown, the base station 2 may have a floor brush cleaning slot 21, and the floor brush cleaning slot 21 is used to clean the floor brush 1 when the cleaning device is stored in the base station 2. Fig.17 As shown, the floor brush cleaning groove 21 may include a brush plate cleaning groove 201 and a roller brush cleaning groove 202. The brush plate 520 in the floor brush 1 may be located in the brush plate cleaning groove 201, and the roller brush 200 may be located in the roller brush cleaning groove 202. The brush plate cleaning groove 201 may clean the brush plate 520, and the roller brush cleaning groove 202 may clean the roller brush 200.

[0274] Continue to see Fig.17 As shown, there may be a connecting channel 203 between the brush plate cleaning tank 201 and the roller brush cleaning tank 202, one end of the connecting channel 203 may be connected to the brush plate cleaning tank 201, and the other end may be connected to the roller brush cleaning tank 202, and the sewage in the brush plate cleaning tank 201 may flow into the roller brush cleaning tank 202 through the connecting channel 203. For example, after the sewage cleaned by the brush plate 520 in the brush plate cleaning tank 201 flows into the roller brush cleaning tank 202 through the connecting channel 203, the sewage may be sucked up by the roller brush 200, and then sucked into the sewage tank by the sewage suction pipe 600 under the action of negative pressure for storage, thereby completing the cleaning work of the cleaning equipment.

[0275] Continue to see Fig.17 As shown, a cleaning contact 2011 may be provided on the bottom of the brush plate cleaning groove 201, and the cleaning contact 2011 is in frictional contact with the brush plate 520. During the cleaning process of the brush plate 520, the brush plate 520 moves back and forth and can rub back and forth with the cleaning contact 2011, so that the cleaning contact 2011 can clean the brush plate 520, thereby effectively improving the cleaning effect of the brush plate 520.

[0276] The height of the end of the connecting channel 203 connected to the brush cleaning tank 201 can be higher than the end of the connecting channel 203 connected to the roller brush cleaning tank 202. In this way, the sewage can flow into the roller brush cleaning tank 202 under the action of gravity, so that the sewage can be sucked into the sewage tank in the roller brush cleaning tank 202, which can reduce or avoid the accumulation of sewage in the brush cleaning tank 201, help improve the cleanliness of the brush cleaning tank 201, and enhance the cleaning effect of the base 521 on the floor brush 1.

[0277] For example, the height of the connecting channel 203 can be gradually reduced from one end of the connecting channel 203 connected to the brush cleaning tank 201 to the end of the connecting channel 203 connected to the roller brush cleaning tank 202. In this way, the sewage in the brush cleaning tank 201 can flow evenly into the roller brush cleaning tank 202, which can improve the smoothness of the sewage flow. In addition, it can also reduce or avoid the phenomenon of sewage accumulation due to many ups and downs in the connecting channel 203, which helps to improve the reliability of sewage flowing to the roller brush cleaning tank 202, thereby effectively improving the cleaning effect of the base station 2.
