Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a floor brush assembly, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment, such as floor scrubbers, is a type of cleaning machinery used to clean surfaces like floors and carpets. It simultaneously vacuums up wastewater and removes it from the site, offering advantages such as environmental friendliness, energy efficiency, and high performance. Some floor scrubbers are equipped with squeegees. These squeegees quickly and effectively remove wastewater and residue from the floor, thus shortening cleaning time and improving efficiency. For example, in some cleaning equipment, the squeegee can be positioned in front of the roller brush. This way, as the scrubber reverses, the squeegee collects dirt from the floor and transfers it to the cleaning equipment via the roller brush, achieving both cleaning and drying of the floor.

[0003] Because the squeegee stirs up dirt and water stains on the floor during the cleaning process, when the cleaning equipment pauses or stops cleaning, water stains remain at the contact point with the floor that cannot be completely scraped away and collected by the roller brush. Furthermore, some water residue on the squeegee surface drips down and onto the contact point with the floor after the equipment stops, making it impossible to clean completely. These factors can easily result in noticeable watermarks around the squeegee contact point after cleaning, affecting not only the cleaning effect of the equipment but also the user's perception and product experience. Utility Model Content

[0004] This application provides a floor brush component, cleaning equipment, and cleaning system that can solve the problem of watermarks remaining around the squeegee during the cleaning process, resulting in incomplete cleaning and thus affecting the cleaning effect.

[0005] In a first aspect, this application provides a floor brush assembly capable of moving along a preset travel direction on a surface to be cleaned, comprising:

[0006] The floor brush body is provided with a main channel and a suction channel. The suction channel corresponds to the surface to be cleaned. The main channel is used to provide a negative pressure environment so that when the main channel and the suction channel are connected, the suction channel is used to collect dirt from the surface to be cleaned.

[0007] A roller brush cover plate is disposed on the floor brush body, and the roller brush cover plate is used to cover at least part of the roller brush.

[0008] A scraper is disposed on the roller brush cover plate and located in front of the main body of the floor brush in the preset travel direction. The scraper is used to clean the dirt on the surface to be cleaned.

[0009] A water stain suction channel is arranged on the rolling brush cover plate, and the water stain suction channel comprises a first end close to the main channel and a second end away from the main channel. The first end is connected with the main channel, and the second end branches into at least two suction ports corresponding to the scraping strips.

[0010] When the water stain suction channel is connected with the main channel, the main channel provides a negative pressure environment for the water stain suction channel to suck the water stains around the scraping strips.

[0011] The ground brush assembly provided by the application is provided with a water stain suction channel. One end of the water stain suction channel can be used to communicate with the main channel, and the other end of the water stain suction channel can be provided with a suction port and correspond to the scraping strips. Therefore, when the water stain suction channel is connected with the main channel, the negative pressure environment in the main channel can be used to make the water stain suction channel also in a negative pressure environment. The water stain suction channel can suck the water stains around the scraping strips through the suction port and suck them into the corresponding sewage recovery container (such as a sewage tank) of the cleaning equipment through the water stain suction channel and the main channel.

[0012] Therefore, the water stains on the scraping strips and the water stains on the surface to be cleaned around the scraping strips can be sucked by the water stain suction channel, so that the ground surface can no longer be left with water stains after cleaning, which is also conducive to reducing the possibility of water stains on the scraping strips seeping downward to the surface to be cleaned, thereby causing secondary pollution of the surface to be cleaned, and improving the cleaning effect.

[0013] Specifically, since the first end of the water stain suction channel is connected with the main channel, the main channel can provide a negative pressure environment for the water stain suction channel when the water stain suction channel is connected with the main channel. Since the second end of the water stain suction channel can branch into at least two suction ports corresponding to the scraping strips, the suction ports can suck the water stains around the scraping strips into the water stain suction channel and into the cleaning equipment under the action of the negative pressure environment when the water stain suction channel is connected with the main channel.

[0014] It should be noted that the scraping strips are in an external environment, so the air pressure at the scraping strips is the same as the air pressure of the external environment. When a negative pressure environment is formed in the water stain suction channel, the air pressure in the water stain suction channel is lower than the air pressure at the scraping strips (the air pressure of the external environment). Therefore, under the action of the air pressure, the water stains in the region of the scraping strips corresponding to the suction ports can be sucked into the water stain suction channel.

[0015] In addition, the scraping strip can be located at the front side of the rolling brush along the preset advancing direction of the floor brush assembly. When the floor brush assembly retreats, the scraping strip can be in contact with the surface to be cleaned for scraping water stains and dirt on the surface to be cleaned. Therefore, the surface of the scraping strip facing the rolling brush is prone to dirt and water stains. The suction port of the water stain suction channel can correspond to the surface of the scraping strip facing the rolling brush to suck the surface of the scraping strip prone to dirt and water stains, so that the accuracy of water stain suction of the scraping strip can be improved, and dirt and water stains can be more effectively avoided from mixing to form sewage and then seeping onto the surface to be cleaned, causing secondary pollution of the surface to be cleaned.

[0016] According to an embodiment of the present application, the floor brush assembly further comprises a first switching member for connecting or blocking the water stain suction channel and the main channel.

[0017] In the embodiment of the present application, the first switching member can be used to control the connection or disconnection of the water stain suction channel and the main channel.

[0018] Specifically, when the first switching member connects the water stain suction channel and the main channel, and a negative pressure environment is generated in the main channel, a negative pressure environment can also be formed in the water stain suction channel. The water stain suction channel can suck the water stains on the scraping strip clean through the suction port. The water stains can enter the main channel through the water stain suction channel and then enter the cleaning equipment.

[0019] It should be noted that when the first switching member connects the water stain suction channel and the main channel, the state of the dirt suction channel is not limited in the embodiment of the present application. At this time, the dirt suction channel can be in a state of being connected with the main channel, or the dirt suction channel can also be in a state of being disconnected with the main channel.

[0020] When the first switching member controls the water stain suction channel and the main channel to be disconnected, no negative pressure environment is formed in the water stain suction channel, and the water stain suction channel does not suck the water stains on the scraping strip at this time. For example, at this time, the scraping strip can be in a state of cleaning the surface to be cleaned.

[0021] It should be noted that when the first switching member blocks the water stain suction channel and the main channel, the state of the dirt suction channel is not limited in the embodiment of the present application. At this time, the dirt suction channel can be in a state of being connected with the main channel, or the dirt suction channel can also be in a state of being disconnected with the main channel.

[0022] According to an embodiment of the present application, when the first switching member connects the water stain suction channel and the main channel, the first switching member blocks the dirt suction channel and the main channel.

[0023] In the embodiments of the present application, the first switching member can be used to control the connection state between the water stain suction passage and the main passage and the connection state between the dirt suction passage and the main passage.

[0024] In some examples, the main passage can be connected to one of the water stain suction passage and the main passage through the first switching member. In other words, only one of the water stain suction passage and the dirt suction passage can be in a state of being connected to the main passage.

[0025] Specifically, when the first switching member connects the water stain suction passage and the main passage, a negative pressure environment generated in the main passage can cause a negative pressure environment to be generated in the water stain suction passage, so as to suck the water stain around the squeegee. At this time, the first switching member can control the dirt suction passage and the main passage not to be connected. That is, the negative pressure environment in the main passage can completely enter the water stain suction passage and is not easy to be dispersed by the dirt suction passage, so that the suction force of the water stain suction passage on the water stain around the squeegee can be improved, and the effect of sucking the water stain can be improved.

[0026] When the first switching member connects the dirt suction passage and the main passage, the first switching member can control the water stain suction passage and the main passage not to be connected. That is, the negative pressure environment in the main passage can completely enter the dirt suction passage, so that the suction force generated by the negative pressure environment can not be easily dispersed to the water stain suction passage, and the suction force can completely act on the to-be-cleaned surface, so as to ensure the cleaning effect on the to-be-cleaned surface.

[0027] According to an embodiment of the present application, the floor brush assembly further comprises a second switching member, which is used to connect or block the dirt suction passage and the main passage.

[0028] In the embodiments of the present application, the water stain suction passage and the dirt suction passage can be independently controlled through the first switching member and the second switching member. The first switching member is used to control the connection state between the water stain suction passage and the main passage. The second switching member is used to control the connection state between the dirt suction passage and the main passage.

[0029] In some examples, when the cleaning mode of the to-be-cleaned surface is started, the second switching member can be used to control the dirt suction passage and the main passage to be connected. At this time, the first switching member can connect the water stain suction passage and the main passage or block the water stain suction passage and the main passage, which is not limited in the embodiments. For example, in order to ensure the suction effect on the to-be-cleaned surface, the first switching member can be used to control the water stain suction passage and the main passage not to be connected, so that the suction force can completely act on the to-be-cleaned surface.

[0030] When the water-wet mode of the suctioning scraping strip is started, the first switching piece can be used to control the communication between the water-wet suction channel and the main channel. At this time, the second switching piece can be used to control the communication or blockage between the dirt suction channel and the main channel, which is not limited in the embodiment. For example, in order to ensure the suction effect of the water-wet scraping strip, the second switching piece can be used to control the non-communication between the dirt suction channel and the main channel, so that the suction force can fully act on the scraping strip.

[0031] According to an embodiment of the present application, the first switching piece is an electromagnetic valve; and / or, the second switching piece is an electromagnetic valve.

[0032] In the embodiment of the present application, the first switching piece can be an electromagnetic valve. During the operation of the cleaning device, the first switching piece can be transmitted with instructions through electric signals. The first switching piece can be controlled to communicate or block the water-wet suction channel and the main channel under the control of the electric signals. Similarly, the second switching piece can also be an electromagnetic valve. During the operation of the cleaning device, the second switching piece can be transmitted with instructions through electric signals. The second switching piece can be controlled to communicate or block the dirt suction channel and the main channel under the control of the electric signals.

[0033] Therefore, by controlling the states of the first switching piece and the second switching piece through electric signals, the automatic switching between the scraping strip suction mode and the cleaning surface to be cleaned mode can be realized, which is beneficial to improve the automation and intelligence of the cleaning device.

[0034] It is easy to understand that the electric control mode for controlling the first switching piece and the second switching piece has simple structure and high operation reliability.

[0035] According to an embodiment of the present application, the brush assembly further comprises a driving unit, which is arranged on the roller brush cover plate and connected with the scraping strip. The driving unit is used to drive the scraping strip to lift up and down, so that the scraping strip has an initial position and a working position.

[0036] When the scraping strip is in the working position, the scraping strip cleans the surface to be cleaned, and the main channel and the dirt suction channel are in communication.

[0037] When the scraping strip is in the initial position, the scraping strip has a spacing with the surface to be cleaned.

[0038] In the embodiments of the present application, the scraping strip can have a change in the horizontal height under the action of the driving unit. For example, the scraping strip can rise or fall. When the scraping strip is located at the working position, the scraping strip is in contact with the surface to be cleaned to scrape off the stains on the surface to be cleaned. At this time, the scraping strip and the rolling brush can work synchronously. The rolling brush can wipe the surface to be cleaned, and the scraping strip can be used to scrape off the water marks generated by the rolling brush on the surface to be cleaned to achieve quick drying of the surface to be cleaned, which is beneficial to shorten the cleaning time and improve the cleaning efficiency. When the scraping strip is located at the initial position, the scraping strip can rise by a distance. At this time, the surface to be cleaned is mainly cleaned by the rolling brush. Therefore, it is easy to understand that the height of the scraping strip at the initial position is higher than the height of the scraping strip at the working position.

[0039] When the scraping strip is located at the working position, the rolling brush and the scraping strip work synchronously. There is always water stain on the scraping strip. At this time, if the first switching piece connects the water stain suction channel and the main channel, the water stain on the scraping strip can be suctioned at the same time in the process of the action of the rolling brush and the scraping strip. Alternatively, the first switching piece can be controlled to block the water stain suction channel and the main channel at this time, in other words, the water stain on the scraping strip can not be suctioned at this time. The negative pressure environment generated by the main channel can act on the dirt suction channel to provide suction force for the dirt suction channel, so as to ensure the cleaning effect of the surface to be cleaned.

[0040] According to an embodiment of the present application, the ground brush assembly further comprises a transmission mechanism, one end of the transmission mechanism is connected with the driving unit, and the other end of the transmission mechanism is connected with the first switching piece. The driving unit drives the scraping strip to rise and drives the transmission mechanism to open the first switching piece.

[0041] In the embodiments of the present application, in the process of driving the scraping strip to move by the driving unit, the driving unit can control the position state of the first switching piece through the transmission mechanism. In other words, the position state of the first switching piece can be controlled by mechanical transmission.

[0042] In the process of driving the scraping strip to rise to the initial position by the driving unit, the first switching piece can be driven to be in the state of connecting the water stain suction channel and the main channel by the transmission mechanism. Therefore, when the driving unit drives the scraping strip to be at the initial position, the driving unit can also make the first switching piece connect the water stain suction channel and the main channel. The scraping strip and the first switching piece can be linked by the driving unit. At this time, the water stain suction channel can use the negative pressure environment of the main channel to suction the scraping strip.

[0043] It should be noted that in the present embodiment, when the scraping strip rises to the initial position, the connection state of the dirt suction channel and the main channel is not limited. The dirt suction channel and the main channel can be connected or not connected.

[0044] According to an embodiment of the present application, when the scraping strip is located at the initial position, the first switching member is controlled to connect the main channel and the water stain suction channel.

[0045] In the embodiment of the present application, when the scraping strip is located at the initial position, the scraping strip has a distance from the surface to be cleaned. The scraping strip can be in an inoperative state. At this time, in order to avoid the water stain on the scraping strip from dripping onto the surface to be cleaned under the action of gravity, the first switching member can be controlled to connect the water stain suction channel and the main channel, and the second switching member can be controlled to separate the dirt suction channel and the main channel. The negative pressure environment generated by the main channel can act on the water stain suction channel, so as to provide suction force for the water stain suction channel, thereby ensuring the suction effect of the scraping strip.

[0046] According to an embodiment of the present application, the rolling brush cover plate is provided with an internal space, and at least part of the water stain suction channel and at least part of the driving unit are located in the internal space.

[0047] In the embodiment of the present application, the water stain suction channel and at least part of the driving unit can be arranged on the rolling brush cover plate. Therefore, the space on the rolling brush cover plate can be used to arrange the driving unit and the water stain suction channel, so as to make the internal structure of the rolling brush cover plate compact, and facilitate the realization of the lightness of the floor brush body.

[0048] In some examples, the water stain suction channel can be arranged inside the rolling brush cover plate. The shell of the rolling brush cover plate can protect the water stain suction channel from being easily damaged by external force, thereby reducing the possibility that the water stain suction channel is damaged and affects the suction effect.

[0049] It is easy to understand that at least part of the driving unit is located in the rolling brush cover plate, which can reduce the exposure of the driving unit and the possibility that the driving unit is easily interfered or impacted by external structures, thereby affecting the movement of the scraping strip.

[0050] According to an embodiment of the present application, the floor brush assembly further comprises a liquid guide pipe, a first end of the water stain suction channel is connected with the main channel through the liquid guide pipe, and the first switching member is arranged on the liquid guide pipe.

[0051] In the embodiment of the present application, the water stain suction channel can be connected with the main channel through the liquid guide pipe. Since the water stain suction channel is arranged on the rolling brush cover plate, the main channel is usually located on the floor brush body, and therefore the first end of the water stain suction channel can be connected with the main channel through the liquid guide pipe.

[0052] It is easy to understand that the liquid guide pipe can be a curved pipe. The curved pipe can be arranged by using the spare space in the floor brush body to avoid other structural members in the space of the floor brush body, thereby reducing the space occupied by the liquid guide pipe.

[0053] According to one embodiment of the present application, the driving unit comprises an adapter connected with the scraping strip, and the adapter is provided with an avoiding through hole corresponding to the suction port and facing the surface of the surface to be cleaned.

[0054] The avoiding through hole is located on the side of the scraping strip facing the side wall of the rolling brush along the movement direction of the ground brush assembly.

[0055] In the embodiment of the present application, the scraping strip can be fixed to the driving unit through the adapter. Since at least part of the water stain suction channel is arranged in the rolling brush cover plate, and the scraping strip needs to be exposed outside the rolling brush cover plate when in the working position to contact the surface to be cleaned. Therefore, the scraping strip is located on the side of the water stain suction channel facing the surface to be cleaned. Correspondingly, the adapter can also be located on the side of the scraping strip facing the surface to be cleaned. Therefore, the adapter needs to be provided with an avoiding through hole corresponding to the suction port. When the water stain suction channel is communicated with the main channel, the water stain on the scraping strip can be sucked into the water stain suction channel through the avoiding through hole and the suction port.

[0056] According to one embodiment of the present application, the side wall of the scraping strip facing the rolling brush is provided with a first flow guide structure, and the suction port sucks the water stain on the scraping strip along the first flow guide structure.

[0057] In the embodiment of the present application, the first flow guide structure can provide a guiding effect for the suction direction of the suction port when the water stain suction channel is in a negative pressure environment, so that the suction port can be directed to the surface of the scraping strip where the water stain is prone to occur, thereby reducing the dispersion of suction force and reducing the possibility of weakening the suction effect on the surface of the scraping strip where the water stain is prone to occur.

[0058] In addition, the first flow guide structure can also have a guiding effect on the water stain on the scraping strip. When the water stain suction channel is communicated with the main channel, the suction port of the water stain suction channel can suck most of the water stain on the scraping strip into the water stain suction channel along the first flow guide structure, avoiding the phenomenon of water stain flowing to other directions and then dripping onto the surface to be cleaned. The first flow guide structure can improve the suction effect on the water stain on the scraping strip.

[0059] According to one embodiment of the present application, the ground brush assembly further comprises a second flow guide structure, the second flow guide structure is detachably connected to at least one of the scraping strip and the adapter, and the second flow guide structure is provided with a flow guide space.

[0060] One end of the second flow guide structure is connected with the suction port, and the other end of the second flow guide structure corresponds to the side wall of the scraping strip facing the rolling brush.

[0061] In the embodiments of the present application, the second flow guide structure can provide a guiding effect for the suction force at the suction port when the water stain suction channel communicates with the main channel, and can also provide a guiding effect for the flow of water stains on the scraping strip to the water stain suction channel.

[0062] In addition, the second flow guide structure in the embodiments of the present application is detachably connected to at least one of the scraping strip and the adapter, so that the second flow guide structure can be conveniently cleaned regularly, thereby reducing the possibility that the second flow guide structure is blocked by water stains or dirt, thereby affecting the suction effect of the water stains on the scraping strip.

[0063] According to an embodiment of the present application, the driving unit is arranged on the rolling brush cover plate and connected to the scraping strip, and the driving unit is used to drive the scraping strip to lift and lower, so that the scraping strip has an initial position and a working position.

[0064] In the vertical direction, the initial position represents that a part of the scraping strip corresponds to the water stain suction channel, and the end of the scraping strip close to the surface to be cleaned has a spacing from the surface to be cleaned.

[0065] In the vertical direction, the working position represents that a part of the scraping strip corresponding to the water stain suction channel has a spacing from the water stain suction channel, and the part of the scraping strip corresponding to the water stain suction channel communicates with the water stain suction channel through a fluid channel, and the end of the scraping strip close to the surface to be cleaned is used to suck the water stains around the scraping strip.

[0066] In the embodiments of the present application, when the scraping strip is in the initial position, the scraping strip has a spacing from the surface to be cleaned. The scraping strip can be in an inactive state. When the scraping strip is in the working position, if the cleaning device pauses or stops cleaning, the scraping strip will suddenly stop scraping at this time, and water stains will be left on the ground in contact with the scraping strip. In order to avoid leaving a row of water marks on the surface to be cleaned around the scraping strip, the first switching piece can be controlled to communicate the water stain suction channel with the main channel, and the second switching piece can be controlled to separate the dirt suction channel from the main channel. The negative pressure environment generated by the main channel can act on the water stain suction channel, so as to provide suction force for the water stain suction channel, thereby ensuring the suction effect of the scraping strip.

[0067] According to an embodiment of the present application, the scraping strip sucks the water stains around the scraping strip on the surface to be cleaned, including:

[0068] The scraping strip is hollow, and the part of the scraping strip corresponding to the water stain suction channel and the end of the scraping strip close to the surface to be cleaned are both provided with through holes to form a fluid channel, the fluid channel communicates with the water stain suction channel to provide a negative pressure environment at the end of the scraping strip close to the surface to be cleaned, and the water stains around the scraping strip on the surface to be cleaned are sucked.

[0069] Secondly, this application provides a cleaning device, including a body and a floor brush assembly as described in any of the above embodiments. The floor brush assembly is connected to the body.

[0070] In this embodiment of the application, by setting a water stain suction channel in the floor brush assembly, the cleaning device can have the function of suctioning water stains on the squeegee, thereby reducing the possibility of water stains on the squeegee dripping onto the surface to be cleaned under the action of gravity, causing secondary pollution to the surface to be cleaned.

[0071] Thirdly, this application provides a cleaning system that may include a base or base station and cleaning equipment. The cleaning equipment may be placed on the base or base station.

[0072] The beneficial effects of the floor brush component provided in this application are as follows: By connecting the water suction channel to the main channel, a negative pressure environment can be created within the main channel, allowing the water suction channel to be connected to the main channel to draw water from the squeegee. The water on the squeegee can be drawn out by the water suction channel, preventing water residue from remaining on the squeegee. This reduces the possibility of water dripping down the squeegee onto the surface to be cleaned, thus minimizing the possibility of secondary contamination and improving cleaning effectiveness.

[0073] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush components, cleaning equipment, and cleaning systems provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0096] The cleaning device provided by the embodiments of the present application can be a scrubber. The scrubber is a device for cleaning the ground and can generally include a brush assembly, a roller brush, a clean water tank, a dirty water tank, and the like. The working principle of the scrubber is as follows: through the high-speed rotation of a motor, the roller brush is driven to rotate at a 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 dirty water and the like are sucked into the dirty water tank through another water channel located behind the roller brush, thereby completing the cleaning process.

[0097] The cleaning device can further include a scraping strip. The scraping strip can be used to scrape the dirty water and residues on the ground to improve the cleaning effect and the cleaning efficiency.

[0098] Specifically, the scraping strip can be located on the side of the roller brush facing a preset advancing direction. When the cleaning device retreats for cleaning, the scraping strip can clean the ground. After the cleaning device stops cleaning, because the scraping strip can scrape dirt and water stains on the ground during the cleaning process, the surface of the scraping strip facing the roller brush can have water stains with dirt residues. The water stains can easily drip down to the ground along the surface of the scraping strip, thereby easily causing secondary pollution to the cleaned ground, affecting the cleaning effect of the cleaning device, and further affecting the user experience.

[0099] Based on the above technical problem, the applicant improves the structure of the existing brush assembly. In the embodiments of the present application, the brush assembly is provided with a water stain suction channel. One end of the water stain suction channel can be used to communicate with the main channel, and the other end of the water stain suction channel can be provided with a suction port and correspond to the scraping strip. Therefore, when the water stain suction channel communicates with the main channel, the negative pressure environment in the main channel can be used to make the water stain suction channel also in a negative pressure environment. The water stain suction channel can suction the water stains on the scraping strip through the suction port. The water stains on the scraping strip can be sucked into the cleaning device through the water stain suction channel and the main channel.

[0100] Therefore, the water stains on the scraping strip can be sucked by the water stain suction channel, so that the water stains on the scraping strip can no longer remain, which is beneficial to reduce the possibility of water stains on the scraping strip seeping downward to the surface to be cleaned, thereby causing secondary pollution of the surface to be cleaned, thereby improving the cleaning effect.

[0101] The floor brush assembly 100, the cleaning device, and the cleaning system provided by the present application are described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0102] Referring to Figures 1 to 4 As shown, the floor brush assembly 100 of the embodiments of the present application can move on the surface to be cleaned in a preset advancing direction. The preset advancing direction can refer to the advancing direction of the floor brush assembly. The floor brush assembly 100 includes a floor brush body 110, a roller brush cover plate 120, a scraping strip 140, and a water stain suction channel 150.

[0103] Referring to Figure 2 The floor brush body 110 is provided with a main channel 111 and a dirt suction channel 112. The dirt suction channel 112 corresponds to the surface to be cleaned. The main channel 111 is used to provide a negative pressure environment, so that when the main channel 111 and the dirt suction channel 112 are communicated, the dirt suction channel 112 is used to collect dirt on the surface to be cleaned.

[0104] The one end of the dirt suction channel 112 can be connected with the main channel 111, and the other end of the dirt suction channel 112 can correspond to the surface to be cleaned. When the dirt suction channel 112 and the main channel 111 are communicated, because the main channel 111 can have a negative pressure environment, the dirt suction channel 112 can also be in a negative pressure environment, so that the dirt suction channel 112 can suck the dirt on the surface to be cleaned to clean the surface to be cleaned.

[0105] In some examples, the dirt suction channel 112 can absorb the dirt collected after the roller brush 130 cleans the ground. The dirt therein can be, but is not limited to, sewage formed by mixing dirt and water. The sewage can be taken away from the surface to be cleaned and sucked into the cleaning device by the dirt suction channel 112.

[0106] In some examples, the cleaning device can include a fan. By starting the fan, a negative pressure environment can be provided for the main channel 111.

[0107] Referring to Figure 2 and Figure 3The rolling brush cover plate 120 can be arranged on the brush body 110. The rolling brush cover plate 120 can be used to cover at least part of the rolling brush 130. The squeegee strip 140 can be arranged on the rolling brush cover plate 120 and located at the front side of the brush body 110 in the preset advancing direction. The squeegee strip 140 can be used to clean dirt on the surface to be cleaned. The water stain suction channel 150 can be arranged on the rolling brush cover plate 120. The water stain suction channel 150 includes a first end 151 close to the main channel 111 and a second end 152 away from the main channel 111. The first end 151 can be used to communicate with the main channel 111. The second end 152 can branch into at least two suction ports 150a. The at least two suction ports 150a correspond to the squeegee strip 140. When the water stain suction channel 150 communicates with the main channel 111, the main channel 111 provides a negative pressure environment for the water stain suction channel 150 to suction the water stain on the squeegee strip 140.

[0108] In the embodiment of the present application, since the first end 151 of the water stain suction channel 150 is connected with the main channel 111, the main channel 111 can provide a negative pressure environment for the water stain suction channel 150 when the water stain suction channel 150 communicates with the main channel 111. Since the second end 152 of the water stain suction channel 150 can branch into at least two suction ports 150a corresponding to the squeegee strip 140, the suction ports 150a can suction the water stain on the squeegee strip 140 into the water stain suction channel 150 and into the cleaning equipment under the action of the negative pressure environment when the water stain suction channel 150 communicates with the main channel 111, so that the water stain on the surface of the squeegee strip 140 is reduced to not easily drip downward under the action of gravity, and even the water stain on the squeegee strip 140 can be completely suctioned, so as to keep the surface of the squeegee strip 140 dry, thereby reducing the possibility of secondary pollution of the surface to be cleaned caused by the water dripping from the squeegee strip 140.

[0109] It should be noted that the squeegee strip 140 is in an external environment, so the air pressure at the squeegee strip 140 is the same as the air pressure of the external environment. When the negative pressure environment is formed in the water stain suction channel 150, the air pressure in the water stain suction channel 150 is lower than the air pressure at the squeegee strip 140 (the air pressure of the external environment). Therefore, under the action of the air pressure, the water stain in the region of the squeegee strip 140 corresponding to the suction port 150a can be suctioned into the water stain suction channel 150.

[0110] In some examples, the main channel 111 can communicate with the sewage tank of the cleaning equipment. Therefore, after the water stain on the squeegee strip 140 enters the water stain suction channel 150 under the action of the air pressure, the water stain can enter the sewage tank through the main channel 111, so that it is not necessary to additionally increase a water tank for collecting the water stain on the squeegee strip 140, which is beneficial to simplify the structure design and reduce the production cost of the product.

[0111] In some examples, the scraping strip 140 can be located at the front side of the rolling brush 130 along the preset advancing direction of the floor brush assembly 100. When the floor brush assembly 100 retreats, the scraping strip 140 can be in contact with the surface to be cleaned for scraping water stains and dirt on the surface to be cleaned. Therefore, the surface of the scraping strip 140 facing the rolling brush 130 is prone to dirt and water stains. The suction port 150a of the water stain suction channel 150 can correspond to the surface of the scraping strip 140 facing the rolling brush 130 to suck the surface of the scraping strip 140 prone to dirt and water stains, so that the accuracy of water stain suction of the scraping strip 140 can be improved, and the mixing of dirt and water stains to form sewage that leaks onto the surface to be cleaned and causes secondary pollution of the surface to be cleaned can be avoided more effectively.

[0112] In some examples, the second end 152 of the water stain suction channel 150 can be divided into at least two suction ports 150a which are spaced apart along the length direction of the scraping strip 140. The number of suction ports 150a can be designed according to the length of the scraping strip 140, so that the suction area of the plurality of suction ports 150a can cover the surface of the scraping strip 140 prone to water stains, and the possibility that the part of the surface of the scraping strip 140 prone to water stains is not subjected to suction and affects the suction effect can be avoided.

[0113] In some implementable manners, referring to FIGS. 1, 2 and 3, Figure 4 and Figure 5 the floor brush assembly 100 of the embodiment of the present application can further include a first switching piece 161. The first switching piece 161 can be used to communicate or block the water stain suction channel 150 and the main channel 111.

[0114] In the embodiment of the present application, the first switching piece 161 can be used to control the communication or non-communication of the water stain suction channel 150 and the main channel 111.

[0115] Specifically, when the first switching piece 161 communicates the water stain suction channel 150 and the main channel 111, and a negative pressure environment is generated in the main channel 111, a negative pressure environment can also be formed in the water stain suction channel 150. The water stain suction channel 150 can suck the water stains on the scraping strip 140 clean through the suction port 150a. The water stains can enter the main channel 111 through the water stain suction channel 150, and then enter the cleaning equipment.

[0116] It should be noted that when the first switching piece 161 communicates the water stain suction channel 150 and the main channel 111, the state of the dirt suction channel 112 is not limited in the embodiment of the present application. At this time, the dirt suction channel 112 can be in a state of communication with the main channel 111, or the dirt suction channel 112 can also be in a state of non-communication with the main channel 111.

[0117] When the first switching piece 161 controls the water stain suction passage 150 to be not communicated with the main passage 111, a negative pressure environment is not formed in the water stain suction passage 150, and at this time, the water stain suction passage 150 does not suck the water stain on the squeegee 140. For example, at this time, the squeegee 140 can be in a state of cleaning the surface to be cleaned.

[0118] It should be noted that when the first switching piece 161 blocks the water stain suction passage 150 and the main passage 111, the state of the dirt suction passage 112 is not limited in the embodiment of the present application. At this time, the dirt suction passage 112 can be in a state of being communicated with the main passage 111, or the dirt suction passage 112 can also be in a state of being not communicated with the main passage 111.

[0119] In some realizable ways, referring to FIG. 1, Figure 5 As shown in FIG. 1, when the first switching piece 161 communicates the water stain suction passage 150 and the main passage 111, the first switching piece 161 can block the dirt suction passage 112 and the main passage 111.

[0120] In the embodiment of the present application, one first switching piece 161 can be used to control the connection state between the water stain suction passage 150 and the main passage 111 and the connection state between the dirt suction passage 112 and the main passage 111. In other words, the first switching piece 161 can be used to control the communication state between the water stain suction passage 150 and the main passage 111 and the communication state between the dirt suction passage 112 and the main passage 111.

[0121] In some examples, the main passage 111 can be communicated with one of the water stain suction passage 150 and the main passage 111 through the first switching piece 161. In other words, only one of the water stain suction passage 150 and the dirt suction passage 112 can be in a state of being communicated with the main passage 111.

[0122] Specifically, when the first switching piece 161 communicates the water stain suction passage 150 and the main passage 111, a negative pressure environment can be formed in the water stain suction passage 150 through the negative pressure environment formed in the main passage 111, so as to suck the water stain on the squeegee 140. At this time, the first switching piece 161 can control the dirt suction passage 112 and the main passage 111 to be not communicated. That is, the negative pressure environment in the main passage 111 can completely enter the water stain suction passage 150, and is not easy to be dispersed by the dirt suction passage 112, so as to improve the suction force of the water stain suction passage 150 on the water stain on the squeegee 140, and is beneficial to improve the effect of sucking the water stain.

[0123] When the first switching piece 161 connects the dirt suction channel 112 and the main channel 111, the first switching piece 161 can make the water stain suction channel 150 not connected with the main channel 111. That is, the negative pressure environment in the main channel 111 can completely enter the dirt suction channel 112, so that the suction force generated by the negative pressure environment can not be easily dispersed to the water stain suction channel 150, and the suction force can completely act on the surface to be cleaned, so as to ensure the cleaning effect on the surface to be cleaned.

[0124] In some examples, since the cleaning device is in the mode of cleaning the surface to be cleaned for a long time, the first switching piece 161 can be set to a state of isolating the water stain suction channel 150 from the main channel 111 for a long time. When it is necessary to suck the squeegee 140, the water stain suction channel 150 and the main channel 111 are connected again.

[0125] In some realizable ways, referring to Figure 6 As shown in the figure, the floor brush assembly 100 can further include a second switching piece 162. The second switching piece 162 can be used to connect or block the dirt suction channel 112 and the main channel 111.

[0126] In the embodiment of the application, the water stain suction channel 150 and the dirt suction channel 112 can be independently controlled by the first switching piece 161 and the second switching piece 162. The first switching piece 161 is used to control the connection state between the water stain suction channel 150 and the main channel 111. The second switching piece 162 is used to control the connection state between the dirt suction channel 112 and the main channel 111.

[0127] In some examples, when the mode of cleaning the surface to be cleaned is started, the second switching piece 162 can be used to control the dirt suction channel 112 and the main channel 111 to be connected. At this time, the first switching piece 161 can connect the water stain suction channel 150 and the main channel 111, or can block the water stain suction channel 150 and the main channel 111, which is not limited in the embodiment. For example, in order to ensure the suction effect on the surface to be cleaned, the first switching piece 161 can be used to control the water stain suction channel 150 and the main channel 111 not to be connected, so that the suction force can completely act on the surface to be cleaned.

[0128] When the water stain mode of sucking the squeegee 140 is started, the first switching piece 161 can be used to control the water stain suction channel 150 and the main channel 111 to be connected. At this time, the second switching piece 162 can connect the dirt suction channel 112 and the main channel 111, or can block the dirt suction channel 112 and the main channel 111, which is not limited in the embodiment. For example, in order to ensure the suction effect on the water stain of the squeegee 140, the second switching piece 162 can be used to control the dirt suction channel 112 and the main channel 111 not to be connected, so that the suction force can completely act on the squeegee 140.

[0129] In some feasible implementations, the first switching element 161 can be a solenoid valve. The second switching element 162 can also be a solenoid valve.

[0130] In this embodiment, the first switching element 161 can be a solenoid valve. During the operation of the cleaning equipment, commands can be transmitted to the first switching element 161 via electrical signals. Under the control of the electrical signals, the first switching element 161 can connect or block the water suction channel 150 and the main channel 111. Similarly, the second switching element 162 can also be a solenoid valve. During the operation of the cleaning equipment, commands can be transmitted to the second switching element 162 via electrical signals. Under the control of the electrical signals, the second switching element 162 can connect or block the sludge suction channel 112 and the main channel 111.

[0131] Therefore, by controlling the state of the first switching element 161 and the second switching element 162 with electrical signals, the automatic switching between the suction scraper 140 mode and the cleaning surface mode can be realized, which is beneficial to improving the automation and intelligence of the cleaning equipment.

[0132] It is easy to understand that controlling the first switching element 161 and the second switching element 162 by means of electronic control is simple in structure and has high operational reliability.

[0133] See also some of the possible implementation methods. Figure 4 and Figure 7 As shown, the floor brush assembly 100 in this embodiment may further include a drive unit 170. The drive unit 170 may be disposed on the roller brush cover plate 120 and connected to the scraper blade 140. The drive unit 170 may be used to drive the scraper blade 140 to rise and fall, so that the scraper blade 140 may have an initial position and a working position.

[0134] When the scraper 140 is in the working position, it can clean the surface to be cleaned. The main channel 111 and the suction channel 112 are connected. When the scraper 140 is in the initial position, there can be a gap between the scraper 140 and the surface to be cleaned.

[0135] In this embodiment, the scraper 140 can change its horizontal height under the action of the drive unit 170. For example, it can rise or fall. When the scraper 140 is in the working position, it contacts the surface to be cleaned to remove dirt. At this time, the scraper 140 and the roller brush 130 can work synchronously. The roller brush 130 can wipe the surface to be cleaned, and the scraper 140 can be used to remove watermarks generated by the roller brush 130 on the surface to be cleaned, so as to achieve quick drying of the surface to be cleaned, which helps to shorten the cleaning time and improve the cleaning efficiency. When the scraper 140 is in the initial position, it can rise a certain distance. At this time, the surface to be cleaned is mainly cleaned by the roller brush 130. Therefore, it is easy to understand that the height of the scraper 140 in the initial position is higher than the height of the scraper 140 in the working position.

[0136] When the blade 140 is in the working position, the brush 130 and the blade 140 work synchronously. There is always water stain on the blade 140. At this time, if the first switching piece 161 connects the water stain suction channel 150 and the main channel 111, the water stain on the blade 140 can be suctioned at the same time in the process of the action of the brush 130 and the blade 140. Alternatively, the first switching piece 161 can be controlled to block the water stain suction channel 150 and the main channel 111 at this time, in other words, the water stain on the blade 140 can not be suctioned at this time. The negative pressure environment generated by the main channel 111 can act on the dirt suction channel 112 entirely, so as to provide suction force for the dirt suction channel 112, thereby ensuring the cleaning effect of the surface to be cleaned.

[0137] In some examples, the driving unit 170 can include a power source (not shown in the figure) and a lifting support 171. One end of the lifting support 171 can be connected with the power source. The power source is used to provide power for the lifting support 171. The other end of the lifting support 171 can be connected with the blade 140, so as to drive the blade 140 to lift by the movement of the lifting support 171.

[0138] It should be noted that the movement direction of the lifting support 171 is not limited to be upward or downward. The function of the lifting support 171 is to change the horizontal height of the blade 140. Therefore, the specific movement direction of the lifting support 171 is not limited.

[0139] In some examples, the power source can be, but is not limited to, a rudder.

[0140] In some realizable ways, the floor brush assembly 100 of the embodiment of the application can further include a transmission mechanism (not shown in the figure). One end of the transmission mechanism is connected with the driving unit 170. The other end of the transmission mechanism is connected with the first switching piece 161. The driving unit 170 can drive the blade 140 to rise, and drive the transmission mechanism to open the first switching piece 161.

[0141] In the embodiment of the application, the driving unit 170 can control the position state of the first switching piece 161 through the transmission mechanism in the process of driving the blade 140 to move. In other words, the position state of the first switching piece 161 can be controlled by mechanical transmission.

[0142] In the process of driving the squeegee 140 to rise to the initial position by the driving unit 170, the first switching piece 161 can be driven to a state of connecting the water stain suction channel 150 and the main channel 111 by the transmission mechanism. Therefore, when the driving unit 170 drives the squeegee 140 to the initial position, the driving unit 170 can also make the first switching piece 161 connect the water stain suction channel 150 and the main channel 111. The squeegee 140 and the first switching piece 161 can be linked by the driving unit 170. At this time, the water stain suction channel 150 can use the negative pressure environment of the main channel 111 to suction the squeegee 140.

[0143] It should be noted that in the present embodiment, the connection state of the sewage suction channel 112 and the main channel 111 is not limited when the squeegee 140 rises to the initial position. The sewage suction channel 112 and the main channel 111 can be connected or not connected.

[0144] In some examples, in the process of driving the squeegee 140 to drop to the working position by the driving unit 170, the first switching piece 161 is controlled to connect the sewage suction channel 112 and the main channel 111 by the transmission mechanism. At this time, one of the water stain suction channel 150 and the sewage suction channel 112 can be connected with the main channel 111. In other words, the first switching piece 161 can be located at a position of blocking the water stain suction channel 150 and the main channel 111. The sewage suction channel 112 can use the negative pressure environment of the main channel 111 to clean the surface to be cleaned.

[0145] In some examples, the second switching piece 162 can also be connected with the driving unit 170 by the transmission mechanism. The driving unit 170 can control the movement state of the first switching piece 161 and the second switching piece 162 at the same time by the transmission mechanism. Alternatively, the second switching piece 162 can also be connected with the driving unit 170 by other mechanical structures. This is not limited in the present application.

[0146] In some examples, the transmission mechanism can be, but is not limited to, a connecting rod mechanism, a gear mechanism, etc.

[0147] In some realizable ways, when the squeegee 140 of the present embodiment is located at the initial position, the first switching piece 161 can be controlled to connect the main channel 111 and the water stain suction channel 150.

[0148] In the embodiments of the present application, when the scraping strip 140 is located at the initial position, the scraping strip 140 has a spacing with the surface to be cleaned. The scraping strip 140 can be in an inoperative state. At this time, in order to avoid water stains on the scraping strip 140 from dripping onto the surface to be cleaned under the action of gravity, the first switching piece 161 can be controlled to connect the water stain suction channel 150 and the main channel 111, and the second switching piece 162 can be controlled to separate the dirt suction channel 112 and the main channel 111. The negative pressure environment generated by the main channel 111 can act on the water stain suction channel 150 entirely, so as to provide suction force for the water stain suction channel 150, thereby ensuring the suction effect of the scraping strip 140.

[0149] In some implementable manners, referring to Figure 2 and Figure 3 It is shown that the rolling brush cover plate 120 is provided with an internal space, and at least part of the water stain suction channel 150 and at least part of the driving unit 170 are located in the internal space.

[0150] In the embodiments of the present application, the water stain suction channel 150 and at least part of the driving unit 170 can be arranged on the rolling brush cover plate 120. Therefore, the space on the rolling brush cover plate 120 can be utilized to arrange the driving unit 170 and the water stain suction channel 150, so that the internal structure of the rolling brush cover plate 120 is compact, which is beneficial to realize the lightness of the brush main body 110.

[0151] In some examples, the water stain suction channel 150 can be arranged in the internal space of the rolling brush cover plate 120. The shell of the rolling brush cover plate 120 can protect the water stain suction channel 150 from being damaged by external force, thereby reducing the possibility that the water stain suction channel 150 is damaged and affects the suction effect.

[0152] It is easy to understand that at least part of the driving unit 170 is located in the rolling brush cover plate 120, which can reduce the exposure of the driving unit 170, so that the driving unit 170 is not easily interfered or impacted by external structures, thereby reducing the possibility that the movement of the scraping strip 140 is affected.

[0153] In some examples, the rolling brush cover plate 120 can include a rolling brush upper cover 121 and a rolling brush lower cover 122. The rolling brush upper cover 121 and the rolling brush lower cover 122 are connected to form a space for accommodating at least part of the driving unit 170 and at least part of the water stain suction channel 150.

[0154] In the embodiments of the present application, the fixing manner of the water stain suction channel 150 is not limited. For example, the water stain suction channel 150 can be fixed on at least one of the rolling brush upper cover 121 and the rolling brush lower cover 122 by clamping, screwing or the like.

[0155] In some implementable manners, referring to Figure 1 and Figure 4As shown, the brush assembly 100 can further include a liquid guide pipe 180. The first end 151 of the water stain suction channel 150 can be connected with the main channel 111 through the liquid guide pipe 180. The first switching member 161 is arranged on the liquid guide pipe 180.

[0156] In the embodiment, the water stain suction channel 150 can be connected with the main channel 111 through the liquid guide pipe 180. Since the water stain suction channel 150 is arranged on the roller brush cover plate 120, the main channel 111 is usually arranged on the brush body 110, and thus the first end 151 of the water stain suction channel 150 can be connected with the main channel 111 through the liquid guide pipe 180.

[0157] It is easy to understand that the liquid guide pipe 180 can be a curved pipe. The curved pipe can be arranged by using the space in the brush body 110 to avoid other structural members in the space of the brush body 110, so as to reduce the space occupied by the liquid guide pipe 180.

[0158] The first switching member 161 can be arranged on the liquid guide pipe 180. In the embodiment, the specific position of the first switching member 161 is not limited. The first switching member 161 can be arranged according to the internal structure layout of the brush body 110. For example, the first switching member 161 can be arranged close to the main channel 111 in the brush body 110.

[0159] In some possible implementation manners, referring to Figure 3 and Figure 7 As shown, the driving unit 170 can further include an adapter 172 connected with the scraping strip 140. The adapter 172 is provided with a avoiding through hole 172a corresponding to the suction port 150a on the surface facing the surface to be cleaned. Along the movement direction of the brush assembly 100, the avoiding through hole 172a is located on the side of the scraping strip 140 facing the roller brush 130, and the avoiding through hole 172a is close to the scraping strip 140.

[0160] In the embodiment, the scraping strip 140 can be fixed to the driving unit 170 through the adapter 172. Since at least part of the water stain suction channel 150 is arranged in the roller brush cover plate 120, and the scraping strip 140 needs to be exposed outside the roller brush cover plate 120 to contact the surface to be cleaned in the working position. Therefore, the scraping strip 140 is located on the side of the water stain suction channel 150 facing the surface to be cleaned. Correspondingly, the adapter 172 can also be located on the side of the scraping strip 140 facing the surface to be cleaned. Therefore, the avoiding through hole 172a corresponding to the suction port 150a needs to be arranged on the adapter 172. When the water stain suction channel 150 is connected with the main channel 111, the water stain on the scraping strip 140 can be sucked into the water stain suction channel 150 through the avoiding through hole 172a and the suction port 150a.

[0161] In some examples, the water stain suction channel 150 can be connected with the lifting support 171. When the power source drives the lifting support 171 to move, the lifting support 171 can make the water stain suction channel 150 move synchronously in the process of moving the squeegee 140, so that the suction port 150a of the water stain suction channel 150 can always correspond to the surface of the squeegee 140, and the distance between the suction port 150a and the squeegee 140 can remain unchanged to ensure the suction effect on the squeegee 140.

[0162] In some examples, the water stain suction channel 150 can be connected with the lifting support 171. When the power source drives the lifting support 171 to move, the lifting support 171 can make the water stain suction channel 150 move synchronously in the process of moving the squeegee 140, so that the suction port 150a of the water stain suction channel 150 can always correspond to the surface of the squeegee 140, and the distance between the suction port 150a and the squeegee 140 can remain unchanged to ensure the suction effect on the squeegee 140. Figure 3 As shown in the figure, the squeegee 140 can be provided with a first flow guide structure 141 on the side wall facing the roller brush 130. The suction port 150a can suck the water stains on the squeegee 140 along the first flow guide structure 141.

[0163] In the embodiments of the present application, the first flow guide structure 141 can provide a guide function for the suction direction of the suction port 150a when the water stain suction channel 150 is in a negative pressure environment, so that the suction port 150a can be directed to the surface of the squeegee 140 where water stains are prone to occur, thereby reducing the dispersion of suction force and reducing the possibility of weakening the suction effect on the surface of the squeegee 140 where water stains are prone to occur.

[0164] In addition, the first flow guide structure 141 can also have a guide function for the water stains on the squeegee 140. When the water stain suction channel 150 is in communication with the main channel 111, the suction port 150a of the water stain suction channel 150 can suck most of the water stains on the squeegee 140 into the water stain suction channel 150 along the first flow guide structure 141, avoiding the phenomenon of water stains flowing to other directions and then dripping onto the surface to be cleaned. The first flow guide structure 141 can improve the suction effect on the water stains on the squeegee 140.

[0165] In some examples, the first flow guide structure 141 can be but is not limited to an inclined guide surface. The inclined guide surface can be arranged in the area close to the squeegee 140 of the avoiding through hole 172a. When the water stain suction channel 150 is in communication with the main channel 111, the inclined guide surface can face the surface of the roller brush 130 towards the squeegee 140, so that the suction force can act on the surface of the squeegee 140 facing the roller brush 130 to concentrate the suction force on the squeegee 140. At this time, the water stains on the squeegee 140 can enter the avoiding through hole 172a along the surface of the squeegee 140 facing the roller brush 130 and the inclined guide surface, so that the water stains on the squeegee 140 can enter the suction port 150a.

[0166] In some examples, the water stain suction channel 150 can be connected with the lifting support 171. When the power source drives the lifting support 171 to move, the lifting support 171 can make the water stain suction channel 150 move synchronously in the process of moving the squeegee 140, so that the suction port 150a of the water stain suction channel 150 can always correspond to the surface of the squeegee 140, and the distance between the suction port 150a and the squeegee 140 can remain unchanged to ensure the suction effect on the squeegee 140. Figure 8As shown, the brush assembly 100 can further include a second flow guide structure 190. The second flow guide structure 190 can be detachably connected to at least one of the wiper strip 140 and the adapter 172, and a flow guide space can be provided in the second flow guide structure 190. The second flow guide structure 190 is connected to the suction port 150a at one end, and the other end of the second flow guide structure 190 corresponds to the side wall of the roller brush 130 facing the wiper strip 140.

[0167] In the embodiment of the present application, the second flow guide structure 190 can provide a guiding effect for the suction force at the suction port 150a when the water stain suction channel 150 is in communication with the main channel 111, and can also provide a guiding effect for the flow direction of the water stain on the wiper strip 140 to the water stain suction channel 150.

[0168] In addition, the second flow guide structure 190 in the embodiment of the present application can be detachably connected to at least one of the wiper strip 140 and the adapter 172, so that the second flow guide structure 190 can be conveniently cleaned regularly, thereby reducing the possibility of the second flow guide structure 190 being blocked by water stains or dirt, which affects the suction effect of the water stain on the wiper strip 140.

[0169] In some examples, the second flow guide structure 190 can be a hollow pipe structure. The second flow guide structure 190 has a first opening 191 and a second opening 192 in communication. The first opening 191 can correspond to the avoidance through hole 172a. The second opening 192 can correspond to the surface of the wiper strip 140 facing the roller brush 130. Therefore, when the water stain suction channel 150 is in communication with the main channel 111, a suction force can be generated at the second opening 192 to suction the water stain on the surface of the wiper strip 140 facing the roller brush 130 into the water stain suction channel 150.

[0170] The connection mode of the second flow guide structure 190 with the wiper strip 140 and the adapter 172 can be, but is not limited to, clamping, plug-in, etc.

[0171] According to an embodiment of the present application, the driving unit 170 is arranged on the roller brush cover plate 120 and connected to the wiper strip 140, and the driving unit 170 is used to drive the wiper strip 140 to ascend and descend, so that the wiper strip 140 has an initial position and a working position.

[0172] In the vertical direction, the initial position part represents that the wiper strip 140 corresponds to the water stain suction channel 150, and the end of the wiper strip 140 close to the surface to be cleaned has a spacing with the surface to be cleaned.

[0173] In the vertical direction, the working position represents that the portion of the scraping strip 140 corresponding to the water stain suction channel 150 has a spacing with the water stain suction channel 150, the portion of the scraping strip 140 corresponding to the water stain suction channel 150 is communicated with the water stain suction channel 150 through the fluid channel, and the end of the scraping strip 140 close to the surface to be cleaned is used to suck the water stain around the scraping strip 140 on the surface to be cleaned.

[0174] In the embodiment of the present application, when the scraping strip 140 is located at the initial position, the scraping strip 140 has a spacing with the surface to be cleaned. The scraping strip 140 can be in an inoperative state. When the scraping strip 140 is located at the working position, if the cleaning device pauses or stops cleaning, at this time, the scraping strip 140 suddenly stops the scraping action, and the position in contact with the ground will leave water stains that cannot be scraped by the scraping strip 140. In order to avoid producing a row of water marks on the surface to be cleaned around the scraping strip 140, the first switching piece 161 can be controlled to communicate the water stain suction channel 150 with the main channel 111, and the second switching piece 162 can be controlled to separate the dirt suction channel 112 from the main channel 111. The negative pressure environment generated by the main channel 111 can be fully applied to the water stain suction channel 150, so as to provide suction force for the water stain suction channel 150, thereby ensuring the suction effect of the scraping strip 140.

[0175] According to an embodiment of the present application, the scraping strip 140 sucks the water stain around the scraping strip 140 on the surface to be cleaned, including:

[0176] The scraping strip 140 is hollow, and the portion of the scraping strip 140 corresponding to the water stain suction channel 150 and the end of the scraping strip 140 close to the surface to be cleaned are both provided with through holes to form fluid channels, the fluid channels are communicated with the water stain suction channel 150 to provide a negative pressure environment at the end of the scraping strip 140 close to the surface to be cleaned, and the water stain around the scraping strip 140 on the surface to be cleaned is sucked.

[0177] The embodiment of the present application also provides a cleaning device, referring to Figure 4 As shown in the figure, the cleaning device can include a floor brush assembly 100 and a machine body.

[0178] The floor brush assembly 100 can be connected with 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.

[0179] In the embodiment of the present application, by arranging the water stain suction channel 150 in the floor brush assembly 100, the cleaning device can have the function of sucking the water stain around the scraping strip 140, thereby reducing the water mark residues around the position in contact with the surface to be cleaned by the scraping strip 140.

[0180] In some examples, the cleaning device can further include a clean water tank and a dirty water tank. The clean water tank and the dirty water tank can be arranged on the floor brush assembly 100 or on the machine body. Alternatively, one of the clean water tank and the dirty water tank can be arranged on the floor brush assembly 100 and the other can be arranged on the machine body. The present application is not limited in this regard.

[0181] 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.

[0182] In some examples, when the cleaning device is placed on the base or the station, clean water can be introduced into the base or the station to clean the roller brush 130. At this time, the scraping strip 140 can be lowered to the working position so that the scraping strip 140 can be cleaned during the cleaning of the roller brush 130, thereby reducing the possibility that the surface of the scraping strip 140 becomes dirty and causes the surface to be cleaned to become dirtier. It should be noted that the water stain suction channel 150 can not be in communication with the main channel 111 during the self-cleaning of the roller brush 130.

[0183] After the self-cleaning of the roller brush 130 is completed, since the scraping strip 140 is in contact with the bottom wall of the base or the station when the scraping strip 140 is in the working position, when the water stain suction channel 150 is in communication with the main channel 111 and the main channel 111 can generate a negative pressure environment, according to a predetermined cleaning logic, a cleaning record, or an external trigger condition based on a user's instruction control, a cleaning step for the water stain suction channel 150 can be started. That is, the water stain suction channel 150 can suck the dirty water in the base or the station after cleaning the roller brush 130 into the dirty water tank in the cleaning device through the water stain suction channel 150. The dirty water can enter the suction port 150a along the scraping strip 140 towards the surface of the roller brush 130.

[0184] In some examples, the base or the station can also be used to wash the roller brush 130 and dry the roller brush 130 to avoid the generation of odor or bacteria due to the long time of the roller brush 130 in a wet state.

[0185] In some examples, the base station can have a charging function. When the cleaning device is placed on the base station, the base station can be charged, and the water can be automatically supplied and discharged. The base and the base station can be a split structure, or the base and the base station can be an integrated structure, which is not limited in the present application.
