Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a floor brush assembly, a cleaning device and a cleaning system. BACKGROUND

[0002] The cleaning device, for example, a scrubber, is a cleaning machine used for cleaning the floor, carpet and other surfaces to be cleaned, and can simultaneously suck and dry the sewage and take the sewage away from the site, having the advantages of environmental protection, energy saving, high efficiency and the like. Some scrubbers are provided with a front squeegee. The front squeegee can quickly and effectively scrape the sewage and residues on the ground, thereby shortening the cleaning time and improving the cleaning efficiency.

[0003] After the scrubber works for a period of time, there will be dirt residues on the front squeegee. Therefore, in the subsequent cleaning operation, it is easy to affect the squeegee operation, resulting in the ground being dirtier after squeegeeing. In the related art, the user needs to manually clean the front squeegee regularly, which is time-consuming and laborious, and affects the user experience. UTILITY MODEL CONTENT

[0004] The present application provides a floor brush assembly, a cleaning device and a cleaning system, which can solve the problem of dirt on the surface of the front squeegee affecting the cleaning effect.

[0005] In a first aspect, the present application provides a floor brush assembly, comprising:

[0006] a floor brush main body;

[0007] a rolling brush, disposed on the floor brush main body, the rolling brush rotating for cleaning the surface to be cleaned;

[0008] a lifting squeegee, movably connected with the floor brush main body, the lifting squeegee comprising a front squeegee and a movable support, along the advancing direction of the floor brush assembly, the front squeegee being located at the front side of the rolling brush, and the movable support being capable of driving the front squeegee to ascend or descend;

[0009] a liquid supply device, located at the front side of the rolling brush along the advancing direction of the floor brush assembly, the liquid supply device being used for supplying liquid to at least part of the surface of the front squeegee facing the rolling brush.

[0010] The front squeegee is used for scraping the sewage and residues on the ground to improve the cleaning effect and efficiency. After the scrubber works for a period of time, there will be dirt residues on the front squeegee. Therefore, in the subsequent cleaning operation, it is easy to affect the squeegee operation, resulting in the ground being dirtier after squeegeeing. In the related art, the user needs to manually clean the front squeegee regularly, which is time-consuming and laborious, and affects the user experience.

[0011] Therefore, the mop assembly provided in the application can supply liquid to the front scraping strip through the liquid supply device arranged on the front side of the rolling brush. The liquid can clean the surface of the front scraping strip facing the rolling brush, so that the dirt on the front scraping strip is cleaned, and the front scraping strip can maintain good water scraping and stain removing effects in the subsequent cleaning process, thereby improving the cleaning effect.

[0012] Since the front scraping strip is located on the front side of the rolling brush, when the mop assembly retreats, the front scraping strip descends to contact the surface to be cleaned. Therefore, the surface of the front scraping strip facing the rolling brush is prone to dirt. The liquid supply device is arranged on the front side of the rolling brush, so that the liquid supply device supplies liquid to at least part of the surface of the front scraping strip facing the rolling brush. The liquid flows through the surface of the front scraping strip facing the rolling brush to clean the surface of the front scraping strip, thereby reducing the possibility that the dirt on the front scraping strip causes the front scraping strip to become dirtier in the subsequent cleaning process, and the front scraping strip can maintain good water scraping and stain removing effects in the subsequent cleaning process, thereby improving the cleaning effect.

[0013] In addition, the rolling brush can spray clean water on the rolling brush to wet the rolling brush during the cleaning of the surface to be cleaned. In the advancing direction of the mop assembly, since the front scraping strip is located on the front side of the rolling brush and has a spacing with the rolling brush, when the mop assembly advances to a position, for example, the mop assembly moves to a corner and cannot continue to advance, the rolling brush cannot continue to advance, and the surface to be cleaned within the spacing between the front scraping strip and the rolling brush cannot be wet cleaned by the rolling brush. The mop assembly starts to retreat, at this time, the front scraping strip performs dry scraping between the surface to be cleaned within the spacing. The dry scraping can affect the cleaning effect of the surface to be cleaned within the spacing, especially for stubborn stains on the surface to be cleaned, the cleaning effect is poor. It can be easily understood that the cleaning effect of dry scraping is lower than that of wet cleaning. When the stubborn stains on the surface to be cleaned are wetted by the liquid, they can become soft and can be easily cleaned by the front scraping strip.

[0014] Based on the above technical problems, in the embodiments of the application, when the mop assembly advances to a position and the mop assembly starts to retreat, the liquid supply device supplies liquid to at least part of the surface of the front scraping strip. The liquid can flow downward along the surface of the front scraping strip to the surface to be cleaned under the action of gravity, so that during the retreat of the mop assembly, the liquid flowing downward on the front scraping strip can be located between the front scraping strip and the rolling brush, so that the surface to be cleaned between the front scraping strip and the rolling brush can be kept wet to improve the cleaning effect of stubborn stains.

[0015] The lifting scraping strip can move relative to the floor brush body. The front scraping strip can be lifted or lowered under the action of the movable support. When the floor brush assembly is in retreat, the front scraping strip can be lowered to be in contact with the surface to be cleaned. The front scraping strip can be used to scrape water stains on the surface to be cleaned, which can dry the surface to be cleaned quickly, thereby improving the cleaning efficiency. On the other hand, the surface to be cleaned can not be left with water marks after drying, thereby improving the cleaning effect. When the floor brush assembly is in advance, the front scraping strip can be lifted. At this time, the front scraping strip can have a spacing with the surface to be cleaned. The liquid supply device can supply liquid to at least part of the surface of the front scraping strip facing the roller brush, so as to clean the front scraping strip by the liquid, thereby realizing self-cleaning of the front scraping strip, and the user can not manually clean the scraping strip, thereby improving the user experience.

[0016] It should be noted that when the sewage generated by cleaning the front scraping strip is likely to flow downward to the surface to be cleaned, the floor brush assembly can be advanced, and the roller brush can clean the sewage generated by cleaning the front scraping strip, thereby reducing the possibility of the sewage generated by cleaning the front scraping strip flowing to the surface to be cleaned and affecting the cleaning effect.

[0017] According to an embodiment of the present application, the liquid supply device is located on the front scraping strip or between the roller brush and the front scraping strip; and at least part of the liquid outlet of the liquid supply device faces the surface of the front scraping strip facing the roller brush.

[0018] In the embodiment of the present application, since at least part of the liquid outlet of the liquid supply device faces the surface of the front scraping strip facing the roller brush, by arranging the liquid supply device on the front scraping strip, the liquid supply device can be kept in connection with the front scraping strip. The liquid provided by the liquid supply device can always flow to the surface of the front scraping strip facing the roller brush, so as to clean the front scraping strip.

[0019] In some examples, at least part of the scraping strip can be located below the liquid supply device, and at least part of the liquid outlet of the liquid supply device faces the surface of the front scraping strip facing the roller brush. Therefore, the liquid provided by the liquid outlet can flow downward along the surface of the front scraping strip under the action of gravity, thereby realizing cleaning of the front scraping strip.

[0020] Alternatively, the liquid supply device can also be located between the roller brush and the front scraping strip. Since the liquid supply device can be located between the roller brush and the front scraping strip, the liquid outlet of the liquid supply device can be arranged to face the surface of the front scraping strip facing the roller brush, so that the liquid provided by the liquid outlet can be directly towards the front scraping strip. The liquid provided by the liquid outlet can directly act on the front scraping strip. Especially when the liquid provided by the liquid outlet has a certain impact force, the dirt on the front scraping strip can be more effectively flushed.

[0021] According to one embodiment of the present application, when the liquid supply device is located between the rolling brush and the front wiping strip, the liquid supply device is connected to the rolling brush upper cover; and the front wiping strip can be raised or lowered relative to the liquid supply device.

[0022] In the embodiment of the present application, when the liquid supply device is located between the rolling brush and the front wiping strip, the liquid supply device is connected to the rolling brush upper cover, so that the liquid supply device can remain in a static state when the front wiping strip is raised or lowered. During the raising or lowering of the front wiping strip, the liquid outlet of the liquid supply device can correspond to different positions of the surface of the front wiping strip, so as to clean the surface of different positions of the front wiping strip, thereby facilitating the increase of the cleaning area of the surface of the front wiping strip and the improvement of the cleaning effect of the front wiping strip.

[0023] According to one embodiment of the present application, the front wiping strip comprises an operating part and a connecting part, and at least one of the operating part and the connecting part corresponds to the liquid supply device when the front wiping strip is in a lowered position.

[0024] In the embodiment of the present application, the operating part can be used to contact the surface to be cleaned, so as to clean the surface to be cleaned. The connecting part can be the area close to the upper end of the front wiping strip. When the front wiping strip is in a lowered position, the liquid outlet of the liquid supply device can correspond to at least one of the operating part and the connecting part. When the front wiping strip is in a raised position, the liquid outlet of the liquid supply device can correspond to the position close to the upper end of the front wiping strip, i.e., the liquid outlet corresponds to the connecting part. The liquid provided by the liquid supply device can flow downward from the connecting part to the operating part under the action of gravity. During the downward flow of the liquid, the surfaces of the connecting part and the operating part facing the rolling brush can be washed, so as to clean the front wiping strip.

[0025] When the front wiping strip is in a raised position, the liquid outlet of the liquid supply device can correspond to the position close to the lower end of the front wiping strip, i.e., the liquid outlet corresponds to the operating part. At this time, the liquid outlet of the liquid supply device can directly act on the operating part of the front wiping strip, so as to clean the area prone to dirt, thereby facilitating the improvement of the cleaning efficiency of the front wiping strip. Moreover, since the liquid supply device remains static, when the front wiping strip is in a lowered position, the liquid outlet of the liquid supply device can clean the connecting part of the front wiping strip. Therefore, in the embodiment, the surfaces of the connecting part and the operating part facing the rolling brush can also be washed.

[0026] According to one embodiment of the present application, the liquid supply device moves synchronously with the front wiping strip, or the front wiping strip moves relative to the liquid supply device; and the liquid outlet of the liquid supply device at least partially faces the surface of the front wiping strip facing the rolling brush.

[0027] In the embodiments of the present application, the liquid supply device can move synchronously with the front scraping strip. When the movable support drives the front scraping strip to ascend or descend, no relative movement occurs between the liquid supply device and the front scraping strip. Therefore, the liquid outlet of the liquid supply device can always correspond to the surface of the front scraping strip facing the rolling brush, so as to ensure the washing effect on the front scraping strip.

[0028] In addition, in the embodiments of the present application, the front scraping strip can move up and down relative to the liquid supply device. When the front scraping strip ascends or descends, the liquid supply device can remain stationary relative to the rolling brush assembly. By ascending or descending of the front scraping strip, the liquid supply device can be directed towards different regions of the surface of the front scraping strip facing the rolling brush, so as to increase the cleaning area of the front scraping strip and improve the cleaning effect on the front scraping strip.

[0029] According to an embodiment of the present application, when the front scraping strip moves up and down relative to the liquid supply device, the liquid supply device is connected with the upper cover of the rolling brush; and the front scraping strip can ascend or descend relative to the liquid supply device.

[0030] In the embodiments of the present application, the liquid supply device can move synchronously with the front scraping strip. When the movable support drives the front scraping strip to ascend or descend, no relative movement occurs between the liquid supply device and the front scraping strip. Therefore, the liquid outlet of the liquid supply device can always correspond to the surface of the front scraping strip facing the rolling brush, so as to ensure the washing effect on the front scraping strip.

[0031] In addition, in the embodiments of the present application, the front scraping strip can move up and down relative to the liquid supply device. When the front scraping strip ascends or descends, the liquid supply device can remain stationary relative to the rolling brush assembly. By ascending or descending of the front scraping strip, the liquid supply device can be directed towards different regions of the surface of the front scraping strip facing the rolling brush, so as to increase the cleaning area of the front scraping strip and improve the cleaning effect on the front scraping strip.

[0032] According to an embodiment of the present application, the number of liquid outlets of the liquid supply device is at least two, and the at least two liquid outlets are arranged along the rolling brush axis direction.

[0033] In the embodiments of the present application, the rolling brush axis direction and the extension direction of the front scraping strip can be the same direction. Therefore, by arranging the at least two liquid outlets along the rolling brush axis direction, different regions of the front scraping strip can be cleaned by the at least two liquid outlets, so as to improve the cleaning effect on the front scraping strip.

[0034] It is easy to understand that the more the number of liquid outlets is, the larger the cleaning area of the front scraping strip is. Therefore, the number of liquid outlets can be reasonably designed according to the length of the front scraping strip. In the embodiments of the present application, the number of liquid outlets is not limited.

[0035] According to an embodiment of the present application, the upper cover of the rolling brush is provided with an internal space in which the movable support is slidably connected, and the movable support moves in the internal space to drive the front scraping strip to rise or fall.

[0036] In the embodiments of the present application, the internal space of the upper cover of the rolling brush can be reasonably utilized so that the movable support can be located in the upper cover of the rolling brush. The movable support can not be easily exposed, thereby reducing the possibility that the movable support is collided by other structures or dust accumulation causes the movable support to be stuck.

[0037] According to an embodiment of the present application, when the liquid supply device is located between the rolling brush and the front scraping strip, the inner wall of the upper cover of the rolling brush and the liquid supply device can have a vertical interval, and part of the movable support can move up and down relative to the liquid supply device in the vertical interval.

[0038] In the embodiments of the present application, since the liquid supply device can be fixed relative to the upper cover of the rolling brush, the liquid supply device and the inner wall of the upper cover of the rolling brush can form a vertical interval. The vertical interval can be used to provide a movement space for part of the movable support to drive the front scraping strip to rise or fall through the movable support.

[0039] The driving unit can be used to drive the movable support to move. In addition, since the vertical interval is formed between the liquid supply device and the inner wall of the upper cover of the rolling brush, the liquid supply device and the upper cover of the rolling brush can limit the movable support to avoid excessive movement of the movable support, thereby affecting the normal operation of the front scraping strip.

[0040] According to an embodiment of the present application, when the liquid supply device is located between the rolling brush and the front scraping strip, the liquid outlet of the liquid supply device is located in the internal space.

[0041] In the embodiments of the present application, by arranging the liquid supply device in the internal space of the upper cover of the rolling brush, the liquid outlet of the liquid supply device can not be easily exposed, so that the dust on the surface to be cleaned can not easily block the liquid outlet when the brush assembly is in the cleaning mode.

[0042] According to an embodiment of the present application, the front scraping strip is provided with bristles on at least part of the surface facing the rolling brush, and at least part of the liquid sprayed by the liquid supply device is sprayed to the bristles.

[0043] In the embodiments of the present application, the bristles act on the surface to be cleaned to clean stubborn stains on the surface to be cleaned, thereby facilitating to improve the cleaning effect on the surface to be cleaned.

[0044] The dirt on the cleaning surface to be cleaned is cleaned by the bristles of the front scraping strip. Dirt is likely to remain on the bristles after the bristles clean the dirt on the cleaning surface to be cleaned. Therefore, at least part of the liquid sprayed by the liquid supply device is sprayed on the bristles, so that the bristles can be self-cleaned. The dirt on the bristles can flow to the cleaning surface to be cleaned under the action of the liquid, and then the dirt on the cleaning surface to be cleaned can be cleaned by the roller brush.

[0045] According to an embodiment of the present application, the bristles are detachably connected to the front scraping strip. When the dirt on the bristles is not washed away, the bristles can be regularly detached and cleaned.

[0046] According to an embodiment of the present application, the end of the bristle is flush with or protrudes downward from the bottom end of the front scraping strip. The bristle is a hard bristle.

[0047] In the embodiment of the present application, the end of the bristle is flush with or protrudes downward from the bottom end of the front scraping strip. This can make the bristle fully contact the cleaning surface to be cleaned, thereby improving the cleaning effect of the bristle on the cleaning surface to be cleaned.

[0048] The bristle can be a hard bristle. The hard bristle can more effectively remove stubborn dirt on the cleaning surface to be cleaned, thereby improving the cleaning effect.

[0049] According to an embodiment of the present application, at least part of the liquid sprayed by the liquid supply device is sprayed on the cleaning surface to be cleaned.

[0050] In the embodiment of the present application, on the one hand, the liquid sprayed by the liquid supply device can act on the surface of the front scraping strip facing the roller brush, so as to clean the front scraping strip. On the other hand, since the front scraping strip has a spacing with the roller brush, when the floor brush assembly advances to a position, the roller brush cannot continue to advance to wet the cleaning surface to be cleaned. When the floor brush assembly is initially started to retreat, the cleaning surface to be cleaned within the spacing between the front scraping strip and the roller brush is in a dry state. Therefore, the liquid sprayed by the liquid supply device can be directly sprayed on the cleaning surface to be cleaned, so as to wet the cleaning surface to be cleaned between the front scraping strip and the roller brush, so that the front scraping strip is no longer dry scraping between the cleaning surface to be cleaned. The liquid can wet the stubborn dirt on the cleaning surface to be cleaned, and the front scraping strip can wet-clean the stubborn dirt on the cleaning surface to be cleaned, thereby improving the cleaning effect of the stubborn dirt.

[0051] In addition, when the front scraping strip wet scrapes on the cleaning surface to be cleaned, the resistance between the front scraping strip and the cleaning surface to be cleaned can be reduced, thereby reducing the friction between the front scraping strip and the cleaning surface to be cleaned, and protecting the cleaning surface to be cleaned. In addition, the reduction of the resistance between the front scraping strip and the cleaning surface to be cleaned can also slow down the movement of the floor brush assembly to a certain extent, thereby reducing the energy consumption.

[0052] According to one embodiment of the present application, the front waterway assembly further comprises a liquid guide pipe, one end of the liquid guide pipe is connected with the liquid supplier, and the other end of the liquid guide pipe is used to be connected with the clean water tank, and the liquid in the clean water tank enters the liquid supplier through the liquid guide pipe.

[0053] In the embodiments of the present application, the front waterway assembly can be used to guide the liquid in the clean water tank into the liquid supplier, so that the liquid supplier can provide liquid to the surface of the front scraper facing the rolling brush. By connecting the front waterway assembly with the clean water tank, the liquid in the clean water tank can be reasonably utilized. The ground brush assembly no longer needs to additionally increase a water tank for cleaning the front scraper, which is beneficial to simplify the structure of the ground brush assembly and reduce the weight of the ground brush assembly.

[0054] According to one embodiment of the present application, the front waterway assembly further comprises a water pump, which is arranged on the ground brush main body and connected with the liquid guide pipe, so as to drive the cleaning liquid in the clean water tank to enter the liquid supplier.

[0055] In the embodiments of the present application, by arranging the water pump, on the one hand, the speed of the liquid in the clean water tank entering the liquid supplier through the liquid guide pipe can be improved when the front scraper is cleaned, so as to realize the rapid self-cleaning of the front scraper. On the other hand, the flow rate of the liquid outlet of the liquid supplier spraying to the front scraper can also be improved, so as to provide a larger washing force for the front scraper by a larger liquid flow rate, which is beneficial to improve the cleaning effect of the front scraper.

[0056] According to one embodiment of the present application, the front waterway assembly further comprises a gas pump and a gas flow pipeline connected with each other, the gas flow pipeline is connected with the liquid supplier or the liquid guide pipe, and the gas pump is used to blow gas into the liquid supplier or the liquid guide pipe.

[0057] In the embodiments of the present application, when the liquid supplier sprays liquid to the front scraper, the gas pump can be started to run. The gas pump can provide gas pressure to the liquid supplier, so that the liquid supplier can provide a gas-liquid mixture to the scraper. The liquid supplier can provide liquid with a higher flow rate and a stronger impact force to quickly wash away the dirt remaining on the front scraper.

[0058] In a second aspect, the present application provides a cleaning device, which comprises the ground brush assembly in any of the above embodiments and a machine body.

[0059] The cleaning device provided in the embodiments of the present application has the function of self-cleaning of the front scraper, so that the possibility that the front scraper becomes dirtier and dirtier when cleaning the surface to be cleaned due to the dirt remaining on the front scraper for a long time can be reduced, and the user no longer needs to manually clean the front scraper, which is beneficial to improve the user experience.

[0060] In a third aspect, the application provides a cleaning system, which comprises:

[0061] a base or a station;

[0062] and the cleaning device described above, which can be placed on the base or the station.

[0063] The base can be used to clean and dry the roller brush to avoid odor or bacteria caused by the long time of the roller brush in a wet state. The station can have a charging function. When the cleaning device is placed on the station, the station can be charged. In addition, the station can also automatically supply water and discharge sewage to realize the functions of automatic water supply and automatic sewage discharge. The base and the station can be a split structure, or the base and the station can be an integrated structure.

[0064] The brush assembly provided by the application has the following beneficial effects: the liquid supply device is arranged on the front side of the roller brush, and the liquid supply device supplies liquid to at least part of the surface of the roller brush facing the front scraper. The liquid flows through the surface of the front scraper where dirt is easy to accumulate, so that the dirt can be cleaned, thereby reducing the possibility that the front scraper continues to clean the ground and causes the ground to be dirtier after being scraped, and realizing self-cleaning of the front scraper, so that the user does not need to manually clean the front scraper. When the brush assembly moves to a position and starts to retreat, because there is a distance between the roller brush and the front scraper that is not wetted by the roller brush, the liquid supply device supplies liquid to the front scraper, and the liquid can flow down from the surface of the front scraper to the surface to be cleaned, so that during the synchronous retreat of the front scraper, the liquid flowing down from the front scraper can be located between the front scraper and the roller brush, thereby avoiding the possibility that the front scraper scratches the surface to be cleaned in the distance that is not wetted by the roller brush, thereby affecting the cleaning effect.

[0065] In addition to the technical problems solved by the above-described embodiments of the application, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features, other technical problems solved by the brush assembly, the cleaning device, and the cleaning system provided by the embodiments of the application, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific embodiments.

[0085] The above drawings have shown the specific embodiments of the present application, which will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0086] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims. It is clear that the described embodiments are a part of, but not all of, embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts are within the scope of protection of the present application.

[0087] The cleaning equipment provided in the embodiments of the present application can be a scrubber. The scrubber is a device for cleaning the ground, which can generally consist of a brush assembly, a roller brush, a clean water tank, a sewage tank and the like. The working principle of the scrubber is as follows: through the high-speed operation of the motor, the roller brush is driven to rotate at high speed, and at the same time, the clean water tank is operated to spray clean water to the roller brush through a water channel. Through the high-speed rotation of the roller brush, the sewage and the like are sucked into the sewage tank through another water channel located behind the roller brush, thereby completing the cleaning process.

[0088] In some examples, the scrubber can further include a front squeegee. The front squeegee can be used to scrape the sewage and residues on the ground to improve the cleaning effect and efficiency. After the scrubber works for a period of time, dirt residues will exist on the front squeegee. Therefore, in subsequent cleaning operations, the scraping operation is easily affected, resulting in the ground being dirtier. In the related art, the user needs to manually clean the front squeegee regularly, which is time-consuming and laborious and affects the user experience.

[0089] Based on the above technical problem, the applicant improves the structure of the existing brush assembly. In the embodiments of the present application, according to the cleaning mode of the brush assembly, the dirt of the front squeegee is usually generated on the side of the front squeegee facing the roller brush. Therefore, by arranging a liquid supply device on the side of the front squeegee facing the roller brush, the liquid supply device can supply liquid to the front squeegee. The liquid can clean the surface of the front squeegee facing the roller brush to clean the dirt on the front squeegee, so that the front squeegee can maintain good scraping and stain removal effects in subsequent cleaning processes, which is beneficial to ensure the cleaning effect. Moreover, the automatic cleaning of the front squeegee can be realized through the liquid supply device, and the user no longer needs to manually clean the front squeegee, which is beneficial to improve the user experience.

[0090] The brush assembly 100, the cleaning equipment and the cleaning system provided in the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0091] Referring to Figure 1As shown, the floor brush assembly 100 can include a floor brush body 110, a rolling brush 120, a lifting squeegee 130, and a liquid supply device 140.

[0092] The rolling brush 120 can be arranged on the floor brush body 110. The rolling brush 120 rotates for cleaning a surface to be cleaned. The lifting squeegee 130 is movably connected to the floor brush body 110. The lifting squeegee 130 includes a front squeegee 131 and a movable bracket 132. The front squeegee 131 is located at a front side of the rolling brush 120 in a forward direction of the floor brush assembly 100. The movable bracket 132 is configured to drive the front squeegee 131 to move up or down.

[0093] The liquid supply device 140 can be arranged at the front side of the rolling brush 120 in the forward direction of the floor brush assembly 100. The liquid supply device 140 is configured to supply liquid to at least part of a surface of the front squeegee 131 facing the rolling brush 120.

[0094] In the embodiment, since the front squeegee 131 is located at the front side of the rolling brush 120, when the floor brush assembly 100 retreats, the front squeegee 131 is lowered to contact the surface to be cleaned. Therefore, the surface of the front squeegee 131 facing the rolling brush 120 is prone to be contaminated. By arranging the liquid supply device 140 at the front side of the rolling brush 120, the liquid supply device 140 can supply liquid to at least part of the surface of the front squeegee 131 facing the rolling brush 120. The liquid flows through the surface of the front squeegee 131 facing the rolling brush 120 to clean the surface of the front squeegee 131, thereby reducing the possibility that the front squeegee 131 is contaminated in the subsequent cleaning process, and the front squeegee 131 can maintain good water wiping and stain removing effects in the subsequent cleaning process, which is conducive to ensuring the cleaning effect.

[0095] In addition, the rolling brush 120 can spray clean water on the rolling brush 120 during cleaning of the surface to be cleaned to wet the rolling brush 120, thereby achieving wet cleaning of the surface to be cleaned. In the forward direction of the floor brush assembly 100, since the front squeegee 131 is located at the front side of the rolling brush 120, the front squeegee 131 has a spacing with the rolling brush 120. Therefore, when the floor brush assembly 100 advances to a position, for example, the floor brush assembly 100 moves to a corner and cannot continue to advance, the rolling brush 120 also cannot continue to advance, and the surface to be cleaned within the spacing between the front squeegee 131 and the rolling brush 120 cannot be wet cleaned by the rolling brush 120. The floor brush assembly 100 starts to retreat, at this time, the front squeegee 131 performs dry wiping between the surface to be cleaned within the spacing. The dry wiping can affect the cleaning effect of the surface to be cleaned within the spacing, especially for stubborn stains on the surface to be cleaned, the cleaning effect is poor. It can be easily understood that the cleaning effect of dry wiping is lower than that of wet cleaning. When the stubborn stains on the surface to be cleaned are wetted by liquid, the stubborn stains can become soft, thereby being cleaned more easily under the action of the front squeegee 131.

[0096] Based on the above technical problems, in the embodiments of the present application, when the floor brush assembly 100 advances to the position and the floor brush assembly 100 starts the retreat operation, the liquid supply device 140 supplies liquid to at least part of the surface of the front scraper 131, and the liquid can flow downward along the surface of the front scraper 131 to the surface to be cleaned under the action of gravity, so that during the retreat operation of the floor brush assembly 100, as the front scraper 131 also retreats synchronously, the liquid flowing down the front scraper 131 can be located between the front scraper 131 and the roller brush 120, so that the surface to be cleaned between the front scraper 131 and the roller brush 120 can be kept wet, so as to improve the cleaning effect on stubborn stains.

[0097] The lifting scraper 130 can move relative to the floor brush body 110. The front scraper 131 can be raised or lowered under the action of the movable support 132. When the floor brush assembly 100 retreats, the front scraper 131 can be lowered to contact the surface to be cleaned. The front scraper 131 can be used to scrape water stains on the surface to be cleaned. On the one hand, it can make the surface to be cleaned dry quickly to improve the cleaning efficiency. On the other hand, it can make the surface to be cleaned dry and not easy to leave water marks to improve the cleaning effect. When the floor brush assembly 100 advances, the front scraper 131 can be raised. At this time, the front scraper 131 and the surface to be cleaned can have a spacing. The liquid supply device 140 can supply liquid to at least part of the surface of the front scraper 131 facing the roller brush 120, so as to clean the front scraper 131 by the liquid, thereby realizing self-cleaning of the front scraper 131, and the user can not manually clean the scraper, which is conducive to improving the user experience.

[0098] It should be noted that when the sewage generated by cleaning the front scraper 131 flows downward to the surface to be cleaned, the floor brush assembly 100 can advance, and the roller brush 120 can clean the sewage generated by cleaning the front scraper 131, thereby reducing the possibility of the sewage generated by cleaning the front scraper 131 flowing to the surface to be cleaned and affecting the cleaning effect.

[0099] In some examples, the floor brush assembly 100 can further include a driving unit for driving the movable support 132 to move. The driving unit can provide a power source for the movable support 132 to drive the front scraper 131 to rise or fall by rising or falling of the movable support 132.

[0100] For example, the driving unit can be, but is not limited to, a steering wheel.

[0101] In some examples, the liquid supply device 140 supplies liquid to the front scraper 131 by providing a mist of water vapor to wet the front scraper 131. Alternatively, the liquid supply method may be that the liquid supply device 140 sprays water jets radially onto the front scraper 131 to clean the surface of the front scraper 131 facing the roller brush 120. This is not limited in this embodiment.

[0102] The liquid used to clean the front scraper 131 can be clean water or a mixture of clean water and cleaning agent, and is not limited in this application.

[0103] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the liquid dispenser 140 of this embodiment can be located on the front scraper 131 or between the roller brush 120 and the front scraper 131. The liquid outlet 140a of the liquid dispenser 140 is at least partially facing the surface of the front scraper 131 facing the roller brush 120.

[0104] In the embodiments of this application, see Figure 2 As shown, since at least a portion of the outlet 140a of the liquid supply device 140 faces the surface of the front scraper 131 facing the roller brush 120, by positioning the liquid supply device 140 on the front scraper 131, the liquid supply device 140 can be kept connected to the front scraper 131. The liquid supplied by the liquid supply device 140 can always flow to the surface of the front scraper 131 facing the roller brush 120 to clean the front scraper 131.

[0105] In some examples, at least a portion of the front scraper 131 may be located below the liquid dispenser 140, and at least a portion of the liquid outlet 140a of the liquid dispenser 140 faces the surface of the front scraper 131 facing the roller brush 120. Therefore, the liquid supplied by the outlet 140a can flow downwards along the surface of the front scraper 131 under gravity, thereby achieving cleaning of the front scraper 131.

[0106] Or see Figure 3 As shown, the liquid supply device 140 can also be located between the roller brush 120 and the front scraper 131. Since the liquid supply device 140 can be located between the roller brush 120 and the front scraper 131, the outlet 140a of the liquid supply device 140 can be positioned directly opposite the surface of the front scraper 131 facing the roller brush 120, so that the liquid supplied by the outlet 140a can directly reach the front scraper 131. The liquid supplied by the outlet 140a can directly act on the front scraper 131. In particular, when the liquid supplied by the outlet 140a has a certain impact force, it can more effectively flush away dirt on the front scraper 131.

[0107] See also some of the possible implementation methods. Figure 3 andFigure 4 As shown, when the liquid supply 140 is located between the rolling brush 120 and the front wiping strip 131, the liquid supply 140 is connected with the rolling brush upper cover 150. The front wiping strip 131 can be raised or lowered relative to the liquid supply 140.

[0108] In the embodiment of the present application, when the liquid supply 140 is located between the rolling brush 120 and the front wiping strip 131, since the liquid supply 140 is connected with the rolling brush upper cover 150, the liquid supply 140 can remain in a static state when the front wiping strip 131 is raised or lowered. During the process of the front wiping strip 131 being raised or lowered, the liquid outlet 140a of the liquid supply 140 can correspond to different positions of the surface of the front wiping strip 131, so as to clean the surface of different positions of the front wiping strip 131, thereby facilitating to improve the cleaning area of the surface of the front wiping strip 131 and improve the cleaning effect of the front wiping strip 131.

[0109] In some examples, the front wiping strip 131 can include an operation part 1311 and a connecting part 1312. The operation part 1311 can refer to the area of the front wiping strip 131 close to the lower end. In other words, the operation part 1311 can be used to contact the surface to be cleaned to clean the surface to be cleaned. The connecting part 1312 can refer to the area of the front wiping strip 131 close to the upper end. When the front wiping strip 131 is located in the lowered position, the liquid outlet 140a of the liquid supply 140 can correspond to at least one of the operation part 1311 and the connecting part 1312.

[0110] When the front wiping strip 131 is located in the raised position, referring to Figure 4 As shown, the liquid outlet 140a of the liquid supply 140 can correspond to the position close to the upper end of the front wiping strip 131, that is, the liquid outlet 140a corresponds to the connecting part 1312. The liquid provided by the liquid supply 140 can flow downward from the connecting part 1312 to the operation part 1311 of the front wiping strip 131 under the action of gravity. During the process of the liquid flowing downward, the surfaces of the connecting part 1312 and the operation part 1311 facing the rolling brush 120 can be washed to clean the front wiping strip 131.

[0111] Alternatively, referring to Figure 5As shown, when the front-positioned scraping strip 131 is in the raised position, the liquid outlet 140a of the liquid supply device 140 can correspond to the position of the lower part of the front-positioned scraping strip 131, that is, the liquid outlet 140a corresponds to the operation part 1311. At this time, the liquid outlet 140a of the liquid supply device 140 can directly act on the operation part 1311 of the front-positioned scraping strip 131 to clean the area prone to dirt, which is beneficial to improve the efficiency of cleaning the front-positioned scraping strip 131. Moreover, since the liquid supply device 140 remains stationary, when the front-positioned scraping strip 131 is in the lowered position, the liquid outlet 140a of the liquid supply device 140 can clean the connecting part 1312 of the front-positioned scraping strip 131. Therefore, in the embodiment, the connecting part 1312 and the surface of the operation part 1311 facing the roller brush 120 can also be cleaned.

[0112] In some implementable manners, referring to Figure 3 and Figure 4 As shown, the liquid supply device 140 can move up and down synchronously with the front-positioned scraping strip 131, or the front-positioned scraping strip 131 can move up and down relative to the liquid supply device 140. The liquid outlet 140a of the liquid supply device 140 at least partially faces the surface of the front-positioned scraping strip 131 facing the roller brush 120.

[0113] In the embodiment, the liquid supply device 140 can move synchronously with the front-positioned scraping strip 131. When the movable support 132 drives the front-positioned scraping strip 131 to rise or fall, no relative movement occurs between the liquid supply device 140 and the front-positioned scraping strip 131. Therefore, the liquid outlet 140a of the liquid supply device 140 can always correspond to at least part of the surface of the front-positioned scraping strip 131 facing the roller brush 120, so as to ensure the flushing effect of the front-positioned scraping strip 131.

[0114] In addition, in the embodiment, the front-positioned scraping strip 131 can move up and down relative to the liquid supply device 140. When the front-positioned scraping strip 131 rises or falls, the liquid supply device 140 can remain stationary relative to the floor brush assembly 100. By rising or falling of the front-positioned scraping strip 131, the liquid supply device 140 can be directed to different areas of the surface of the front-positioned scraping strip 131 facing the roller brush 120, so as to increase the cleaning area of the front-positioned scraping strip 131 and improve the cleaning effect of the front-positioned scraping strip 131.

[0115] In some implementable manners, referring to Figure 3 and Figure 4 As shown, when the front-positioned scraping strip 131 moves up and down relative to the liquid supply device 140, the liquid supply device 140 is connected with the roller brush upper cover 150. The front-positioned scraping strip 131 can rise or fall relative to the liquid supply device 140.

[0116] In the embodiments of the present application, the liquid supply device 140 is connected to the roller brush upper cover 150, and the liquid supply device 140 can be kept stationary relative to the roller brush upper cover 150. Since the front scraper 131 can be lifted and moved relative to the roller brush upper cover 150 under the action of the movable support 132, the front scraper 131 can be lifted or lowered relative to the liquid supply device 140.

[0117] When the front scraper 131 is in the lifted position or the lowered position, the liquid outlet 140a of the liquid supply device 140 corresponds to different surface positions of the front scraper 131, and thus the surface of the front scraper 131 in different positions can be cleaned through the lifting and moving of the front scraper 131.

[0118] In some implementable manners, as shown in Figure 3 and Figure 4 The roller brush upper cover 150 can be provided with an internal space for sliding connection of the movable support 132. The movable support 132 can move in the internal space to drive the front scraper 131 to be lifted or lowered.

[0119] In the embodiments of the present application, the internal space of the roller brush upper cover 150 can be reasonably utilized so that the movable support 132 can be located in the roller brush upper cover 150. The movable support 132 can not be easily exposed, thereby reducing the possibility of the movable support 132 being collided by other structures or causing the accumulation of dust to cause the phenomenon of jamming.

[0120] In some examples, when the movable support 132 drives the front scraper 131 to move to the lowered position, the front scraper 131 can be used to clean the surface to be cleaned. At this time, the front scraper 131 is in a working state, and the front scraper 131 can not be cleaned. When the movable support 132 drives the front scraper 131 to move to the lifted position, the cleaning effect on the front scraper 131 can be started.

[0121] In some examples, when the liquid supply device 140 is located between the roller brush 120 and the front scraper 131, the inner wall of the roller brush upper cover 150 and the liquid supply device 140 can have a vertical spacing 150a. Part of the movable support 132 can be lifted or lowered relative to the liquid supply device 140 in the vertical spacing 150a to drive the front scraper 131 to be lifted or lowered.

[0122] In the embodiments of the present application, since the liquid supply device 140 can be fixed relative to the roller brush upper cover 150, the liquid supply device 140 and the inner wall of the roller brush upper cover 150 can form a vertical spacing 150a. The vertical spacing 150a can be used to provide a movement space for part of the movable support 132 to drive the front scraper 131 to be lifted or lowered through the movable support 132.

[0123] The driving unit can be configured to drive the movable support 132 to move. In addition, since the liquid supply device 140 and the inner wall of the rolling brush upper cover 150 form a vertical space 150a for the movable support 132 to move, the liquid supply device 140 and the rolling brush upper cover 150 can limit the movable support 132 to avoid excessive movement of the movable support 132 and affect the normal operation of the front scraping strip 131.

[0124] In some examples, when the liquid supply device 140 is located between the rolling brush 120 and the front scraping strip 131, the liquid supply device 140 can be completely located in the internal space of the cover plate of the rolling brush 120. The liquid outlet 140a of the liquid supply device 140 can not be exposed.

[0125] In the embodiment of the present application, by arranging the liquid supply device 140 in the internal space of the cover plate of the rolling brush 120, the liquid outlet 140a of the liquid supply device 140 can not be easily exposed, so that the dust on the surface to be cleaned cannot easily block the liquid outlet 140a when the brush assembly 100 is in the cleaning mode.

[0126] In some realizable manners, the number of liquid outlets 140a of the liquid supply device 140 in the embodiment of the present application is at least two. The at least two liquid outlets 140a can be arranged along the axis direction of the rolling brush 120.

[0127] In the embodiment of the present application, the axis direction of the rolling brush 120 and the extension direction of the front scraping strip 131 can be the same direction. Therefore, by arranging the at least two liquid outlets 140a along the axis direction of the rolling brush 120, the different areas of the front scraping strip 131 can be cleaned through the at least two liquid outlets 140a, which is beneficial to improve the cleaning effect of the front scraping strip 131.

[0128] It is easy to understand that the more the number of liquid outlets 140a is, the larger the cleaning area of the front scraping strip 131 is. Therefore, the number of liquid outlets 140a can be reasonably designed according to the length of the front scraping strip 131. The number of liquid outlets 140a is not limited in the embodiment of the present application.

[0129] In some realizable manners, at least part of the surface of the front scraping strip 131 facing the rolling brush 120 in the embodiment of the present application can be provided with bristles. At least part of the liquid sprayed by the liquid supply device 140 is sprayed to the bristles.

[0130] In the embodiment of the present application, the bristles act on the surface to be cleaned, which can clean stubborn stains on the surface to be cleaned, thereby being beneficial to improve the cleaning effect of the surface to be cleaned.

[0131] After the bristles of the front scraping strip 131 clean dirt on the surface to be cleaned, dirt is likely to remain on the bristles. Therefore, at least part of the liquid sprayed by the liquid supply device 140 can be sprayed on the bristles, so that self-cleaning of the bristles can be achieved. Dirt on the bristles can flow to the surface to be cleaned under the action of the liquid, and then the dirt on the surface to be cleaned can be cleaned by the roller brush 120.

[0132] In some examples, the bristles can be detachably connected to the front scraping strip 131. When dirt on the bristles is not washed clean, the bristles can be regularly detached and cleaned.

[0133] In some examples, the bristles can be detachably connected to the front scraping strip 131. When dirt on the bristles is not washed clean, the bristles can be regularly detached and cleaned.

[0134] It should be noted that the detachable connection manner of the bristles and the front scraping strip 131 is not limited in the embodiments of the present application. For example, a dovetail groove can be arranged on the front scraping strip 131. The bristles can be mounted in the dovetail groove in the direction of the axis of the roller brush 120.

[0135] In some realizable manners, the end of the bristle is flush with the bottom end of the front scraping strip 131 or protrudes downward from the bottom end of the front scraping strip 131.

[0136] In the embodiments of the present application, by arranging that the end of the bristle is flush with the bottom end of the front scraping strip 131 or protrudes downward from the bottom end of the front scraping strip 131, the bristle can be fully in contact with the surface to be cleaned, so that the cleaning effect of the bristle on the surface to be cleaned can be improved.

[0137] In some realizable manners, the bristle can be a hard bristle. The hard bristle can more effectively remove stubborn dirt on the surface to be cleaned, which is conducive to improving the cleaning effect.

[0138] In some realizable manners, referring to FIGS. 1 and 2, at least part of the liquid sprayed by the liquid supply device 140 can be sprayed on the surface to be cleaned. Figure 2 Figure 5 In some realizable manners, referring to FIGS. 1 and 2, at least part of the liquid sprayed by the liquid supply device 140 can be sprayed on the surface to be cleaned.

[0139] ​In this embodiment, on one hand, the liquid sprayed by the liquid dispenser 140 can act on the surface of the front scraper 131 facing the roller brush 120 to clean the front scraper 131. On the other hand, since there is a gap between the front scraper 131 and the roller brush 120, when the floor brush assembly 100 moves forward to its position, the roller brush 120 cannot continue to move forward and wet the surface to be cleaned. When the floor brush assembly 100 initially starts its backward movement, the surface to be cleaned between the front scraper 131 and the roller brush 120 within the aforementioned gap is dry. Therefore, the liquid sprayed by the liquid dispenser 140 directly sprays onto the surface to be cleaned, which can wet the surface between the front scraper 131 and the roller brush 120, so that the front scraper 131 is no longer dry scraping with the surface to be cleaned within the aforementioned gap, and the liquid can wet the stubborn stains on the surface to be cleaned. The front scraper 131 can wet-clean the stubborn stains on the surface to be cleaned, which is beneficial to improving the cleaning effect on stubborn stains.

[0140] Furthermore, when the front scraper 131 wet-scrapes the surface to be cleaned, it can reduce the resistance between the front scraper 131 and the surface to be cleaned, which helps to reduce the friction between the surfaces and protect them. In addition, the reduced resistance between the front scraper 131 and the surface to be cleaned can also reduce the movement resistance of the floor brush assembly 100 to a certain extent, thus reducing energy consumption.

[0141] See also some of the possible implementation methods. Figure 6 As shown, the floor brush assembly 100 may further include a front water channel assembly. The front water channel assembly may include a liquid guide pipe 160. One end of the liquid guide pipe 160 may be connected to the liquid dispenser 140. The other end of the liquid guide pipe 160 is used to connect to the clean water tank 200. Liquid in the clean water tank 200 enters the liquid dispenser 140 through the liquid guide pipe 160.

[0142] In this embodiment, the front water channel assembly can be used to guide the liquid in the clean water tank 200 into the liquid supply device 140, so that the liquid supply device 140 can provide liquid to the surface of the front scraper 131 facing the roller brush 120. By connecting the front water channel assembly to the clean water tank 200, the liquid in the clean water tank 200 can be utilized efficiently. The floor brush assembly 100 no longer needs an additional water tank for cleaning the front scraper 131, which simplifies the structure of the floor brush assembly 100 and reduces its weight.

[0143] See also some of the possible implementation methods. Figure 6 As shown, the front water circuit assembly may also include a water pump 170. The water pump 170 may be mounted on the floor brush body 110. The water pump 170 is connected to a liquid guide pipe 160 to drive the cleaning fluid in the clean water tank 200 into the liquid supply device 140.

[0144] In the embodiments of the present application, the water pump 170 is arranged. On one hand, the water pump 170 can improve the speed of the liquid in the clean water tank 200 entering the liquid supply device 140 through the liquid guide pipe 160 when the front scraper 131 is cleaned, so that the front scraper 131 can be quickly self-cleaned. On the other hand, the flow rate of the liquid sprayed from the liquid outlet 140a of the liquid supply device 140 to the front scraper 131 can be improved, so that the front scraper 131 can be provided with a larger washing force through a larger liquid flow rate, and the cleaning effect of the front scraper 131 can be improved.

[0145] In some possible implementation manners, referring to FIG. 1, Figure 6 As shown in FIG. 1, the front water path assembly further includes a gas pump 180 and a gas flow pipeline 190 connected thereto. The gas flow pipeline 190 is connected to the liquid supply device 140 or the liquid guide pipe 160. The gas pump 180 can be used to supply gas to the liquid supply device 140 or the liquid guide pipe 160.

[0146] In the embodiments of the present application, when the liquid supply device 140 sprays liquid to the front scraper 131, the gas pump 180 can be started to operate. The gas pump 180 can provide gas pressure to the liquid supply device 140, so that the liquid supply device 140 can provide a gas-liquid mixture to the front scraper 131. The liquid supply device 140 can provide liquid with a high flow rate and a strong impact force, so that the dirt remaining on the front scraper 131 can be quickly washed away.

[0147] In some examples, the gas flow pipeline 190 can be connected to the liquid supply device 140, so that the gas pump 180 can directly provide gas pressure to the liquid supply device 140. Alternatively, the gas flow pipeline 190 can be connected to the liquid guide pipe 160. The gas pump 180 can provide gas pressure to the liquid guide pipe 160, and the gas is introduced into the liquid supply device 140 through the liquid guide pipe 160, so that the mixing uniformity of the gas-liquid mixture in the liquid supply device 140 can be improved. The embodiments of the present application are not limited in this regard.

[0148] The embodiments of the present application further provide a cleaning device. The cleaning device can include the floor brush assembly 100 and a machine body.

[0149] The floor brush assembly 100 can be connected to the machine body. During the operation of the cleaning device, the user can push the machine body to make the floor brush assembly 100 advance or retreat.

[0150] Since the liquid supply device 140 for cleaning the front scraper 131 is arranged on the floor brush assembly 100, the cleaning device provided by the embodiments of the present application can have the function of self-cleaning the front scraper 131, so that the possibility that the front scraper 131 becomes dirtier and dirtier after being used for a long time can be reduced, and the user does not need to manually clean the front scraper 131, which is beneficial to improving the user experience.

[0151] In some examples, the cleaning device can further include a clean water tank 200 and a dirty water tank. The clean water tank 200 and the dirty water tank can be arranged on the brush assembly 100 or on the machine body. Alternatively, one of the clean water tank 200 and the dirty water tank can be arranged on the brush assembly 100 and the other can be arranged on the machine body. The present application is not limited in this regard.

[0152] The present application also provides a cleaning system. The cleaning system can include a base or a station. The cleaning device can be placed on the base or the station.

[0153] In some examples, the base can be used to wash the roller brush 120 and dry the roller brush 120 to avoid odor or bacteria caused by the long time of the roller brush 120 in a wet state.

[0154] In some examples, the station can have a charging function. When the cleaning device is placed on the station, the station can be charged, and the water can be automatically supplied and drained. The base and the station can be a split structure or an integrated structure, and the present application is not limited in this regard.
