Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning technology, and more specifically to a cleaning device. Background Technology
[0002] Cleaning equipment such as floor scrubbers are cleaning machines suitable for cleaning surfaces such as floors and carpets, while simultaneously sucking up and removing wastewater from the site. They offer advantages such as environmental friendliness, energy efficiency, and high efficiency. A roller brush cover can partially cover the roller brush to protect it from damage caused by contact with hard objects during the cleaning process.
[0003] During the cleaning process, the rotating roller brush of a floor scrubber creates friction between the bristles and the surface to be cleaned, thus achieving cleaning. When the scrubber returns to its base, the roller brush can perform self-cleaning. However, in related technologies, during the self-cleaning process, the rotating roller brush can easily throw debris, wastewater, and other dirt generated during the self-cleaning process onto the air outlet on the base and the surrounding walls, leading to secondary pollution. Utility Model Content
[0004] This application provides a cleaning device that can solve the problem of secondary pollution caused by dirt generated by the roller brush during the self-cleaning process of the roller brush cover.
[0005] In a first aspect, this application provides a cleaning device, comprising:
[0006] Floor brush assembly, the floor brush assembly comprising:
[0007] The main body of the floor brush;
[0008] A roller brush is rotatably connected to the main body of the floor brush.
[0009] A roller brush cover is disposed on the main body of the floor brush. Along the traveling direction of the main body of the floor brush, the end of the roller brush cover located in front of the roller brush is provided with a front scraper. The roller brush cover is flipped relative to the main body of the floor brush so that the front scraper moves up or down.
[0010] A drive unit is disposed on the brush body, and the drive unit is used to drive the roller brush cover to flip.
[0011] A control module, connected to the drive unit, is used to control the drive unit to drive the roller brush cover to flip.
[0012] The base has a platform for placing the floor brush assembly and an air outlet. When the floor brush assembly is placed on the base, the floor brush assembly has a drying mode and a self-cleaning mode.
[0013] When the floor brush assembly is in the drying mode, the control module controls the roller brush cover to flip upward, and there is a gap between the bottom of the front scraper and the placement platform so that the hot air blown out of the air outlet can reach the roller brush.
[0014] When the floor brush assembly is in the self-cleaning mode, the control module controls the roller brush cover to flip downwards, the bottom of the front scraper is in contact with the placement platform, and the front scraper blocks the roller brush and the air outlet.
[0015] The cleaning device provided in this application allows the floor brush assembly to be controlled into a self-cleaning mode when the roller brush needs cleaning. In this mode, the roller brush cover can be flipped downwards so that the bottom of the front scraper on the cover can fit against the placement platform. In other words, there is no gap between the bottom of the front scraper and the placement platform. Therefore, when the roller brush rotates to clean its inner wall, the dirt generated during the cleaning process can be blocked by the roller brush cover and the front scraper, reducing the possibility of dirt being thrown onto the air outlet of the base and the wall surface, thus preventing secondary contamination of the cleaning device.
[0016] The air outlet on the base can provide hot air to the roller brush in drying mode. When dirt generated by the rotating roller brush enters the air outlet, it can easily enter the internal space of the base, leading to the accumulation of dirt and bacteria or odors. It can also affect the working performance and lifespan of the internal components of the base.
[0017] After the roller brush and roller brush cover have finished cleaning, the floor brush assembly can be controlled to enter drying mode. The air vent on the base can be used to supply hot air to the roller brush. At this time, the roller brush cover can be flipped upwards to move the front scraper upwards. There can be a gap between the bottom of the front scraper and the placement platform. Therefore, hot air can be blown from the air vent through the gap to the roller brush to dry it, thereby reducing the possibility of odors or bacteria developing due to the roller brush being in a damp state for an extended period.
[0018] According to one embodiment of this application, in the self-cleaning mode, the front scraper is sealed to the placement platform, and the front scraper blocks the space of the roller brush facing the air outlet of the base.
[0019] In this embodiment, along the travel direction of the floor brush assembly, the roller brush and the air outlet are located on both sides of the front scraper. By setting the front scraper to be sealed to the placement platform, the front scraper can block the space of the roller brush facing the air outlet of the base, so that the dirt generated by the rotation of the roller brush can be blocked by the front scraper, thereby avoiding the possibility of dirt entering the air outlet of the base or contaminating the base wall.
[0020] Specifically, along the direction of travel of the brush assembly, the front scraper is sealed to the mounting platform, dividing the space on the platform into a front space and a rear space. The air outlet of the base is located in the front space. The roller brush is located in the rear space. The front and rear spaces are relatively sealed by the partitioning effect of the front scraper. Dirt thrown out during the rotation of the roller brush can be blocked in the rear space of the front scraper by the roller brush cover and the front scraper, and is not easy to enter the front space.
[0021] In some examples, because the front scraper is flexible, there can be a certain amount of interference between the bottom of the front scraper and the placement platform when the bottom of the front scraper is in contact with the placement platform, so that the bottom of the front scraper and the placement platform can have better sealing, thereby more effectively preventing the roller brush from throwing dirt towards the air outlet of the base.
[0022] According to one embodiment of this application, in the self-cleaning mode, the roller brush abuts against the inner wall of the roller brush cover, and the inner wall of the roller brush cover contacts the bristles of the roller brush.
[0023] During the rotation of the roller brush, dirt on its surface is easily flung onto the inner wall of the roller brush cover, causing dirt to accumulate on the inner wall. Users need to disassemble the roller brush to clean the inner wall of the roller brush cover, which is not conducive to automating the cleaning process, and is time-consuming and laborious, affecting the user experience.
[0024] Therefore, in this embodiment, when the floor brush assembly is in self-cleaning mode, the roller brush cover can be controlled to flip downwards to abut against the inner wall of the roller brush cover. Through the rotation of the roller brush, the roller brush can rub against the inner wall of the roller brush cover, thus cleaning the inner wall and achieving self-cleaning. When the user activates the self-cleaning mode of the floor brush assembly, self-cleaning of the roller brush and the roller brush cover can be achieved.
[0025] It's easy to understand that the roller brush abuts against the inner wall of the roller brush cover. The roller brush cover can extend deep into the bristles of the roller brush. Therefore, during the rotation of the roller brush, there can be a relative squeezing force between the roller brush and the inner wall of the roller brush cover. On the one hand, this increases the friction between the roller brush and the inner wall of the roller brush cover, thereby improving the cleaning effect on the inner wall of the roller brush cover. On the other hand, the inner wall of the roller brush cover can also provide a greater force to the roller brush, squeezing out dirt deep within the bristles. The roller brush cover can provide a kneading force to the roller brush, kneading the bristles and squeezing out dirt protruding from the bristles through the liquid.
[0026] According to one embodiment of this application, a water-equalizing structure is provided between the roller brush cover and the roller brush, the water-equalizing structure extending along the axial direction of the roller brush, and in the self-cleaning mode, at least a portion of the water-equalizing structure penetrates into the bristles of the roller brush.
[0027] In this embodiment, at least a partial water-uniform structure can extend into the bristles of the roller brush, and the water-uniform structure can improve the uniformity of the liquid on the roller brush.
[0028] It's easy to understand that uneven liquid distribution on the roller brush can affect drying efficiency and lead to functional wear. Furthermore, after drying, the roller brush may remain damp in certain areas, potentially causing bacterial growth or unpleasant odors. Additionally, uneven liquid distribution on the roller brush can leave watermarks on the surface being cleaned, affecting the cleaning effect.
[0029] Therefore, in this embodiment of the application, during the cleaning process of the floor brush assembly, when the water distributor sprays liquid onto a portion of the roller brush, the roller brush rotates and comes into contact with the inner wall of the roller brush cover. At this time, the inner wall of the roller brush cover can provide a squeezing force to the roller brush, pushing the excess liquid on the roller brush in a localized direction to the surrounding area. This allows the liquid to be evenly distributed on the roller brush, improving the uniformity of liquid distribution and thus increasing drying efficiency. It also reduces the possibility of watermarks appearing on the surface to be cleaned due to uneven liquid distribution on the roller brush.
[0030] Furthermore, by extending at least partially into the bristles of the roller brush, the water-distributing structure can deeply clean the dirt on the roller brush. Through the rotation of the roller brush, the water-distributing structure provides a deep squeezing force, forcing the liquid deep into the bristles. The liquid and the dirt deep within the brush bristles can be thoroughly mixed. Then, through the deep squeezing and frictional force provided by the water-distributing mechanism, the liquid and dirt deep within the brush bristles are carried out together, thus achieving deep cleaning of the roller brush and improving the cleaning effect on the surface to be cleaned.
[0031] According to one embodiment of this application, the water distribution structure seals the roller brush cover and the roller brush along the radial direction of the roller brush.
[0032] In this embodiment, a gap exists between part of the roller brush and the inner wall of the roller brush cover. During rotation, the roller brush easily picks up liquids and dirt. Dirt can easily clog the gap, affecting the rotation of the roller brush. Liquid can easily enter the brush body, affecting the performance and lifespan of the internal structure. The water-distributing structure can act as a sealant. The water-distributing structure can prevent dirt from being drawn into the gap, reducing the possibility of dirt clogging the gap and causing the roller brush to malfunction.
[0033] Furthermore, the water distribution structure can be used to prevent liquids and dirt from entering the interior of the brush body through the gap between the roller brush and the roller brush cover, so as to avoid liquids or dirt entering the brush body and affecting the operational reliability of the internal structure of the brush body.
[0034] Furthermore, when the floor brush assembly is in drying mode, the water distribution structure can also be used to evenly distribute the hot air across the roller brush surface. Because the water distribution structure has a sealing effect, it can prevent hot air from flowing towards the floor brush assembly, allowing the hot air to accumulate between the roller brush cover and the roller brush. As hot air continues to be supplied from the air outlet, the amount of hot air between the roller brush cover and the roller brush gradually increases. The water distribution structure effectively evens out the airflow. Because of the obstruction effect of the water distribution structure, the hot air cannot continue to flow upwards along the outer periphery of the roller brush, and it will accumulate in the area near the water distribution structure. The hot air can then flow along the extension direction of the water distribution structure, drying the brush bristles in that direction. This more effectively improves the uniformity and efficiency of drying the roller brush, preventing localized dampness that could lead to bacterial growth or odors, and also reducing the possibility of watermarks appearing on the surface to be cleaned due to localized dampness of the roller brush.
[0035] According to one embodiment of this application, after the bottom of the front scraper is attached to the placement platform, the roller brush cover, the front scraper, at least part of the placement platform, and the floor brush body form a closed sealing structure along the circumference of the roller brush.
[0036] In this embodiment, when the roller brush rotates, dirt and liquid on the roller brush are thrown towards the outer periphery of the roller brush under the action of centrifugal force. For example, dirt is thrown out along the tangential direction of the roller brush. When the roller brush cover is controlled to flip downward so that the bottom of the front scraper is in contact with the placement platform, the circumferential space of the roller brush can be sealed by the roller brush cover, the front scraper, at least part of the placement platform, and the brush body. This allows dirt to be blocked within the closed sealing structure and is not easily thrown out in other directions, which helps to avoid secondary pollution caused by dirt being thrown out.
[0037] This application provides a cleaning device, which includes:
[0038] Floor brush assembly, the floor brush assembly comprising:
[0039] The main body of the floor brush;
[0040] A roller brush is rotatably connected to the main body of the floor brush.
[0041] A roller brush cover is disposed on the main body of the floor brush. Along the traveling direction of the main body of the floor brush, the end of the roller brush cover located in front of the roller brush is provided with a front scraper. The roller brush cover is flipped relative to the main body of the floor brush so that the front scraper moves up or down.
[0042] A drive unit is disposed on the brush body, and the drive unit is used to drive the roller brush cover to flip.
[0043] A control module, connected to the drive unit, is used to control the drive unit to drive the roller brush cover to flip.
[0044] The base has a platform for placing the floor brush assembly. When the floor brush assembly is placed on the base, the floor brush assembly has a self-cleaning mode and a drying mode.
[0045] When the floor brush assembly is in the self-cleaning mode, the control module controls the roller brush cover to flip downward so that the bottom of the front scraper is in contact with the placement platform;
[0046] When the floor brush assembly is in the drying mode, the control module controls the roller brush cover to flip upward so that there is a gap between the bottom of the front scraper and the placement platform for hot air to blow onto the roller brush.
[0047] In this embodiment, in self-cleaning mode, the front scraper can be in contact with the placement platform. There is no gap between the front scraper and the placement platform. Therefore, the dirt rolled up during the rotation of the roller brush can be prevented from being thrown onto the wall of the base on the side of the front scraper facing away from the roller brush by the obstruction of the front scraper and part of the roller brush cover.
[0048] After the roller brush is cleaned, the floor brush assembly can be switched to drying mode to dry the roller brush and prevent it from remaining damp for extended periods, which could lead to bacterial growth or unpleasant odors. In drying mode, the roller brush cover can be flipped upwards, and the bottom of the front scraper can be moved away from the placement platform, creating a gap between the bottom of the front scraper and the platform. This gap allows hot air to flow through to the roller brush for drying.
[0049] According to one embodiment of this application, in the drying mode, along the traveling direction of the brush body, the gap corresponds to the air outlet of the base, so that the hot air from the air outlet blows onto the roller brush through the gap.
[0050] In this embodiment, the base is provided with an air outlet. The air outlet can be used to provide hot air. In drying mode, the roller brush cover is flipped upwards, which creates a gap between the bottom of the front scraper and the placement platform. The air outlet corresponds to this gap, allowing the hot air from the air outlet to reach the roller brush through the gap and dry the roller brush.
[0051] According to one embodiment of this application, in the drying mode, the opening width of the air outlet is less than or equal to the gap between the front scraper and the placement table.
[0052] In this embodiment, by setting the opening width of the air outlet to be less than or equal to the gap between the front scraper and the placement table, the hot air released from the air outlet can enter the gap between the front scraper and the placement table as much as possible, or even all of it, and be provided to the roller brush. This helps to reduce the loss of hot air.
[0053] In some examples, the width direction of the air outlet opening can refer to the height direction of the floor brush assembly. The gap between the front wiper blade and the mounting platform can refer to the gap between the front wiper blade and the mounting platform along the height direction of the floor brush assembly.
[0054] When the hot air at the air outlet flows towards the roller brush, it tends to rise due to its lower density. By setting the opening width of the air outlet to be less than or equal to the gap between the front scraper and the placement platform, the hot air flowing upward at the air outlet can also easily enter the roller brush through the gap, thereby improving the utilization rate of hot air and allowing more hot air to act on the roller brush, which helps to reduce the loss of hot air.
[0055] According to one embodiment of this application, in the drying mode, there is a gap between the roller brush cover plate and the roller brush along the radial direction of the roller brush, and a sealing element is provided within the gap, the sealing element extending along the axial direction of the roller brush;
[0056] Along the circumference of the roller brush, the seal is close to the brush body to seal the area where the spacing is close to the brush body.
[0057] In this embodiment, during the drying mode, the roller brush cover is flipped upwards, and there is a radial gap between the inner wall of the roller brush cover and the roller brush. During rotation, the roller brush easily picks up liquids and dirt. These liquids and dirt can easily clog the gap between the roller brush cover and the roller brush, affecting the rotation of the roller brush. In particular, the gap between the inner wall of the roller brush cover and the roller brush is smaller in the area near the main body of the brush, making it easier for dirt to accumulate in this gap and further hindering the rotation of the roller brush. Therefore, by providing a seal near the main body of the brush, this gap can be sealed, effectively reducing the possibility of dirt clogging the gap and preventing the roller brush from rotating.
[0058] According to one embodiment of this application, in the drying mode, an airflow guiding channel is formed between the inner wall of the roller brush cover and the roller brush, so that a portion of the hot air provided by the air outlet flows upward along the outer periphery of the roller brush.
[0059] In this embodiment, the hot air supplied by the air outlet of the base can be blown towards the roller brush through the gap between the bottom of the front scraper and the placement platform. The hot air has a certain flow velocity. When the hot air contacts the outer peripheral surface of the roller brush, it can be split into two sets of airflows along the shape of the roller brush. One set of airflows can flow into the space between the roller brush and the placement platform, while the other set of airflows can flow upwards along the outer periphery of the roller brush and enter the space between the roller brush and the inner wall of the roller brush cover. Thus, along the height direction of the floor brush assembly, the hot air can dry the upper and lower areas of the roller brush. As the roller brush rotates, the hot air can be more evenly distributed on the outer periphery of the roller brush, thereby improving the drying uniformity of the roller brush and enhancing the drying effect.
[0060] Specifically, as hot air rises along the outer circumference of the roller brush, its lower density causes it to flow upwards easily. The roller brush cover prevents this upward flow. In other words, the cover concentrates the hot air between itself and the brush, ensuring continuous contact between the hot air and the brush bristles, thus improving heat utilization and reducing heat loss.
[0061] Furthermore, it's easy to understand that as hot air flows away from the air outlet on the base, its temperature gradually decreases, affecting the drying effect. The roller brush cover can concentrate the hot air between the cover and the roller brush. This concentration slows down the rate at which the hot air temperature decreases, thereby improving drying efficiency.
[0062] Furthermore, because the seal is located between the inner wall of the roller brush cover and the roller brush, and extends axially along the roller brush, the seal can prevent hot air from flowing towards the brush assembly, allowing the hot air to accumulate between the roller brush cover and the roller brush. As hot air is continuously supplied from the air outlet, the amount of hot air between the roller brush cover and the roller brush gradually increases. The seal can also even out the airflow. Because of the seal's obstruction, the hot air cannot continue to flow upwards along the outer circumference of the roller brush, and it accumulates in the area near the seal. The hot air can then flow along the extension direction of the seal, drying the brush bristles in that direction, thus more effectively improving the drying effect and efficiency of the roller brush. This avoids localized dampness that could lead to bacterial growth or odors, and also reduces the possibility of watermarks appearing on the surface being cleaned due to localized dampness of the roller brush.
[0063] It should be noted that when the local brush unit is in self-cleaning mode, the seal can also be used as a water distribution structure. The seal provides squeezing force to the roller brush, which on the one hand makes the liquid sprayed on the roller brush by the water distributor more even, thereby improving drying efficiency; on the other hand, it can squeeze out dirt deep in the roller brush along with the liquid, thereby improving the cleanliness of the roller brush and the cleaning effect on the surface to be cleaned.
[0064] Furthermore, in self-cleaning mode, the roller brush can clean both the roller brush itself and the inner wall of the roller brush cover. After self-cleaning, moisture remains on the inner walls of the roller brush and the roller brush cover. In drying mode, hot air flows through the airflow channel between the inner wall of the roller brush cover and the roller brush. This hot air dries both the roller brush and the inner wall of the roller brush cover, reducing residual moisture. This reduces the possibility that residual water from the inner wall of the roller brush cover might flow onto the surface to be cleaned, thus affecting the cleaning effect.
[0065] According to one embodiment of this application, in the drying mode, the airflow guide channel has a narrow throat area, and along the flow direction of the hot air in the airflow guide channel, the narrow throat area is close to the front scraper.
[0066] In this embodiment, by setting a narrow throat area in the region of the airflow guide channel near the front scraper, the hot air can reach a higher flow rate in the narrow throat area. As the hot air leaves the narrow throat area and continues to flow along the airflow guide channel, the flow rate of the hot air can continue to increase, thereby accelerating the rate of moisture evaporation on the roller brush surface and improving the drying efficiency of the roller brush.
[0067] Specifically, after the hot air enters the gap between the bottom of the front scraper and the placement table through the air outlet, it can first enter the narrow throat area. The opening width of the narrow throat area is smaller than the opening width of the gap between the bottom of the front scraper and the placement table; therefore, the flow velocity of the hot air increases in the narrow throat area. As the airflow continues upward along the airflow channel from the narrow throat area, the opening width of the airflow guide channel can increase, and the resistance of the airflow guide channel to the hot air gradually decreases, allowing the flow velocity of the hot air to continue to increase, thereby improving the drying efficiency of the roller brush.
[0068] According to one embodiment of this application, along the height direction of the floor brush assembly, the base is provided with a shielding member opposite to the placement platform; in the drying mode, after the front scraper is flipped upward, it abuts against the shielding member.
[0069] In this embodiment, the shielding component can have a sealing function in the drying mode. By abutting against the shielding component, the front scraper and the shielding component can fit together, preventing hot air from easily escaping to the outside of the base, thereby reducing heat loss and allowing more of the hot air from the air outlet to act on the roller brush, thus improving the drying efficiency of the roller brush.
[0070] The beneficial effects of the cleaning equipment provided in this application are as follows: When the floor brush assembly is in self-cleaning mode, the roller brush rotates to clean its own inner wall. When dirt generated by the roller brush during cleaning is flung outwards, the roller brush cover and front scraper act as a barrier to prevent the dirt from being flung towards the air outlet, thus reducing the possibility of dirt being thrown onto the air outlet of the base and the wall surface, leading to secondary pollution of the cleaning equipment.
[0071] After the roller brush is cleaned, the floor brush assembly can be switched to drying mode. The roller brush cover can be flipped upwards, and the bottom of the front scraper can be moved away from the placement table, so that a gap can be formed between the bottom of the front scraper and the placement table. Hot air can then flow through this gap to the roller brush to dry it, preventing the roller brush from being in a damp state for a long time, which could lead to bacterial growth or odor.
[0072] 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 as described above, other technical problems that the cleaning equipment provided by the embodiments of the present invention can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0087] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0088] This application provides a cleaning device, which may be, but is not limited to, a floor scrubber. This application uses a floor scrubber as an example. A floor scrubber is a device used for cleaning floors and generally consists of multiple parts such as a brush assembly, a roller brush, a clean water tank, and a wastewater tank. The working principle of the floor scrubber is as follows: the high-speed rotation of the motor drives the roller brush to rotate at high speed, while the clean water tank rotates, spraying clean water forward onto the roller brush through a water path. In conjunction with the high-speed rotation of the roller brush, wastewater is drawn into the wastewater tank through a vacuum suction channel located behind the roller brush and another water path, thus completing the cleaning process.
[0089] During the cleaning process, the rotating roller brush of a floor scrubber creates friction between the bristles and the surface to be cleaned, thus achieving cleaning. However, in related technologies, during the self-cleaning process, the rotating roller brush can easily throw debris, wastewater, and other dirt generated during the self-cleaning process onto the air outlet on the base and the surrounding walls, leading to secondary pollution.
[0090] Based on the aforementioned technical problems, the applicant has improved the structure of existing cleaning equipment. In this embodiment, the roller brush cover can be flipped relative to the floor brush body. The floor brush assembly can have a self-cleaning mode and a drying mode. When the floor brush assembly is in self-cleaning mode, the bottom of the front scraper of the roller brush cover can fit against the placement platform of the base. Therefore, when the roller brush rotates for self-cleaning, the dirt rolled up by the roller brush rotation can be blocked by the roller brush cover and the front scraper, preventing the dirt from being thrown onto the wall of the base and reducing the possibility of secondary pollution.
[0091] After the roller brush and roller brush cover are cleaned, the floor brush assembly can be put into drying mode. At this time, the roller brush cover can be flipped upward so that the bottom of the front scraper is no longer in contact with the placement table, so that hot air can be blown onto the roller brush through the gap between the front scraper and the placement table to dry the roller brush.
[0092] The cleaning equipment 10 provided in this application will now be described with reference to the accompanying drawings and specific embodiments.
[0093] See Figures 1 to 4 As shown, the cleaning device 10 may include a floor brush assembly 100 and a base 200. When the floor brush assembly 100 is placed on the base 200, the base 200 can clean the floor brush assembly 100.
[0094] In some examples, the base 200 may also have a charging function. When the floor brush assembly 100 is placed on the base 200, the floor brush assembly 100 can be charged.
[0095] The floor brush assembly 100 may include a floor brush body 110, a roller brush 120, a roller brush cover plate 130, a drive unit, and a control module.
[0096] The roller brush 120 is rotatably connected to the floor brush body 110. The roller brush cover plate 130 is disposed on the floor brush body 110. Along the traveling direction X of the floor brush body 110, the end of the roller brush cover plate 130 located in front of the roller brush 120 is provided with a front scraper 140. The roller brush cover plate 130 is flipped relative to the floor brush body 110 so that the front scraper 140 moves up or down.
[0097] During the cleaning process, the front scraper 140 can move downwards by flipping the roller brush cover 130. The bottom of the front scraper 140 can contact the surface to be cleaned, so that when the floor brush assembly 100 is pulled back, the front scraper 140 can scrape away water stains on the surface after the roller brush 120 has cleaned it, reducing or eliminating water stains that form after the surface dries, and improving cleaning efficiency. When the floor brush assembly 100 is pushed forward, the front scraper 140 can move upwards to prevent it from pushing dirt forward away from the suction port of the floor brush body 110, thus affecting the cleaning effect.
[0098] The drive unit is located on the brush body 110. The drive unit is used to drive the roller brush cover 130 to rotate. The control module is connected to the drive unit to control the drive unit to drive the roller brush cover 130 to rotate.
[0099] The base 200 has a placement platform 210 for placing the floor brush assembly 100 and an air outlet 200a. When the floor brush assembly 100 is placed on the base 200, the floor brush assembly 100 has a drying mode and a self-cleaning mode.
[0100] See Figure 1 and Figure 2 As shown, when the floor brush assembly 100 is in drying mode, the control module controls the roller brush cover 130 to flip upwards. A gap t1 exists between the bottom of the front scraper 140 and the placement platform 210 to allow hot air from the air outlet 200a to reach the roller brush 120. See also... Figure 3 and Figure 4 As shown, when the floor brush assembly 100 starts the self-cleaning mode, the control module controls the roller brush cover 130 to flip downwards. The bottom of the front scraper 140 is in contact with the placement platform 210, and the front scraper 140 blocks the roller brush 120 and the air outlet 200a.
[0101] In this embodiment, when the roller brush 120 needs to be cleaned, the floor brush assembly 100 can be controlled to be in self-cleaning mode. At this time, the roller brush cover 130 can be flipped downwards so that the bottom of the front scraper 140 on the roller brush cover 130 can fit against the placement platform 210. In other words, there is no gap t1 between the bottom of the front scraper 140 and the placement platform 210. Therefore, when the roller brush 120 rotates to clean its own inner wall, the dirt generated by the roller brush 120 during the cleaning process can be blocked by the roller brush cover 130 and the front scraper 140, thereby reducing the possibility of dirt being thrown onto the air outlet 200a of the base 200 and the wall surface, causing secondary pollution of the cleaning equipment 10.
[0102] The air outlet 200a of the base 200 can be used to provide hot air to the roller brush 120 in the drying mode. When the dirt generated by the rotation of the roller brush 120 enters the air outlet 200a, the dirt can easily enter the internal space of the base 200, which can easily accumulate inside the base 200 and produce bacteria or odors. In addition, it can also affect the working performance and service life of the internal components of the base 200.
[0103] After the roller brush 120 and roller brush cover 130 have finished cleaning, the floor brush assembly 100 can be controlled to enter a drying mode. The air outlet 200a of the base 200 can be used to provide hot air to the roller brush 120. At this time, the roller brush cover 130 can be flipped upwards to allow the front scraper 140 to move upwards. A gap t1 can be present between the bottom of the front scraper 140 and the placement platform 210. Therefore, hot air can be blown from the air outlet 200a through the gap t1 onto the roller brush 120 to dry it, thereby reducing the possibility of the roller brush 120 being in a damp state for an extended period, which could lead to odors or bacteria.
[0104] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, in self-cleaning mode, the front scraper 140 is sealed to the placement platform 210. The front scraper 140 can block the space of the roller brush 120 toward the air outlet 200a of the base 200.
[0105] In this embodiment, along the traveling direction X of the floor brush assembly 100, the roller brush 120 and the air outlet 200a are located on both sides of the front scraper 140. By setting the front scraper 140 to be sealed to the placement platform 210, the front scraper 140 can block the space of the roller brush 120 facing the air outlet 200a of the base 200. Thus, the dirt generated by the rotation of the roller brush 120 can be blocked by the front scraper 140, so as to avoid the possibility of dirt entering the air outlet 200a of the base 200 or contaminating the wall surface of the base 200.
[0106] It is easy to understand that, along the axial direction of the roller brush 120, the size of the front scraper 140 is larger than the size of the roller brush 120, and the size of the roller brush cover plate 130 can also be larger than the size of the roller brush 120. Therefore, when the front scraper 140 is sealed to the placement platform 210, the front scraper 140 and the roller brush cover plate 130 can completely cover the roller brush 120 to prevent the dirt generated by the rotation of the roller brush 120 from being thrown towards the air outlet 200a.
[0107] Specifically, along the travel direction X of the floor brush assembly 100, it is sealed to the placement platform 210 via the front scraper 140. The front scraper 140 divides the space on the placement platform 210 into a front space and a rear space. The air outlet 200a of the base 200 is located in the front space. The roller brush 120 is located in the rear space. The front space and the rear space can be relatively sealed by the partitioning effect of the front scraper 140. Dirt thrown out during the rotation of the roller brush 120 can be blocked in the rear space of the front scraper 140 by the roller brush cover plate 130 and the front scraper 140, and is not easy to enter the front space.
[0108] In some examples, because the front scraper 140 is flexible, when the bottom of the front scraper 140 is in contact with the placement platform 210, there can be a certain amount of interference between the bottom of the front scraper 140 and the placement platform 210, so that the bottom of the front scraper 140 and the placement platform 210 can have better sealing, thereby more effectively preventing the roller brush 120 from rotating and throwing dirt towards the air outlet 200a of the base 200.
[0109] See also some of the possible implementation methods. Figure 4 As shown, in self-cleaning mode, the roller brush 120 abuts against the inner wall of the roller brush cover 130. The inner wall of the roller brush cover 130 is in contact with the bristles of the roller brush 120.
[0110] During the rotation of the roller brush 120, dirt on its surface is easily flung onto the inner wall of the roller brush cover 130, causing dirt to accumulate on the inner wall of the roller brush cover 130. Users need to disassemble the roller brush 120 to clean the inner wall of the roller brush cover 130, which is not conducive to automating the cleaning process, is time-consuming and laborious, and affects the user experience.
[0111] Therefore, in this embodiment, when the floor brush assembly 100 is in self-cleaning mode, the roller brush cover 130 can be controlled to flip downwards to abut against the inner wall of the roller brush cover 130. Through the rotation of the roller brush 120, the roller brush 120 can rub against the inner wall of the roller brush cover 130, thus cleaning the inner wall of the roller brush cover 130 and achieving self-cleaning. When the user activates the self-cleaning mode of the floor brush assembly 100, the roller brush 120 and the roller brush cover 130 can achieve self-cleaning.
[0112] It is easy to understand that the roller brush 120 abuts against the inner wall of the roller brush cover plate 130. The roller brush cover plate 130 can extend deep into the bristles of the roller brush 120. Therefore, during the rotation of the roller brush 120, there can be a relative squeezing force between the roller brush 120 and the inner wall of the roller brush cover plate 130. On the one hand, this can increase the friction between the roller brush 120 and the inner wall of the roller brush cover plate 130, thereby improving the cleaning effect on the inner wall of the roller brush cover plate 130. On the other hand, the inner wall of the roller brush cover plate 130 can also provide a greater force to the roller brush 120 to squeeze out dirt deep within the bristles of the roller brush 120. The roller brush cover plate 130 can provide a kneading force to the roller brush 120 to knead the bristles of the roller brush 120 and squeeze out the dirt protruding from the bristles of the roller brush 120 through the liquid.
[0113] See also some of the possible implementation methods. Figure 4 As shown, a water-distributing structure 150 may be provided between the roller brush cover plate 130 and the roller brush 120 in this embodiment of the application. At least a portion of the water-distributing structure 150 extends along the axial direction of the roller brush 120. In self-cleaning mode, the water-distributing structure 150 extends deep into the bristles of the roller brush 120.
[0114] In this embodiment, the water-uniform structure 150 can extend into the bristles of the roller brush 120 at least partially, thereby improving the uniformity of the liquid on the roller brush 120.
[0115] It's easy to understand that uneven liquid distribution on the roller brush 120 can affect drying efficiency and lead to functional loss. Furthermore, after drying, the roller brush 120 is prone to localized dampness, which can cause bacterial growth or unpleasant odors. Additionally, when the liquid distribution on the roller brush 120 is uneven, the floor brush assembly 100 can easily leave watermarks on the surface to be cleaned during the cleaning process, thus affecting the cleaning effect.
[0116] Therefore, in this embodiment of the application, during the cleaning process of the floor brush assembly 100, when the water distributor sprays liquid onto a portion of the roller brush 120, the roller brush 120 rotates and comes into contact with the inner wall of the roller brush cover plate 130. At this time, the inner wall of the roller brush cover plate 130 can provide a squeezing force to the roller brush 120, thereby squeezing the excess liquid on the roller brush 120 to the surrounding area. This allows the liquid to be evenly distributed on the roller brush 120, improving the uniformity of liquid distribution on the roller brush 120, thereby improving drying efficiency and reducing the possibility of watermarks appearing on the surface to be cleaned due to uneven liquid distribution on the roller brush 120.
[0117] Furthermore, by extending at least partially into the bristles of the roller brush 120, the water-distributing structure 150 can deeply clean the dirt on the roller brush 120. Through the rotation of the roller brush 120, the water-distributing structure 150 provides a deep squeezing force to the roller brush 120, forcing the liquid deep into the bristles. The liquid and the dirt deep within the bristles of the roller brush 120 can be thoroughly mixed. Then, through the deep squeezing and frictional force provided by the water-distributing mechanism, the liquid and dirt deep within the bristles of the roller brush 120 are carried out together, thereby achieving deep cleaning of the roller brush 120 and improving the cleaning effect on the surface to be cleaned.
[0118] In some examples, the water distribution structure 150 can be disposed on the inner wall of the roller brush cover plate 130. The water distribution structure 150 and the roller brush cover plate 130 can be an integral structure or a detachable connection, which is not limited in the embodiments of this application.
[0119] It should be noted that the embodiments of this application do not limit the specific structure of the water distribution structure 150. For example, the water distribution structure 150 may have an arc surface facing the roller brush 120.
[0120] See also some of the possible implementation methods. Figure 4 As shown, along the radial direction of the roller brush 120, the water distribution structure 150 seals the roller brush cover plate 130 and the roller brush 120.
[0121] In this embodiment, a gap exists between part of the roller brush 120 and the inner wall of the roller brush cover plate 130. During rotation, the roller brush 120 easily picks up liquids and dirt. Dirt can easily clog the gap, affecting the rotation of the roller brush 120. Liquid can easily enter the floor brush body 110, affecting the working performance and service life of the internal structure of the floor brush body 110. The water distribution structure 150 can act as a sealant 160 to provide a sealing function. The water distribution structure 150 can prevent dirt from being rolled into the gap, reducing the possibility of dirt clogging the gap and causing the roller brush 120 to fail to rotate.
[0122] Furthermore, the water distribution structure 150 can be used to prevent liquids and dirt from entering the interior of the floor brush body 110 through the gap between the roller brush 120 and the roller brush cover plate 130, so as to avoid liquids or dirt entering the floor brush body 110 and affecting the operational reliability of the internal structure of the floor brush body 110.
[0123] Furthermore, when the floor brush assembly 100 is in drying mode, the water distribution structure 150 can also be used to evenly distribute the hot air on the surface of the roller brush 120. Since the water distribution structure 150 has a sealing function, it can prevent hot air from flowing towards the floor brush assembly 100, allowing the hot air to accumulate between the roller brush cover 130 and the roller brush 120. As the air outlet 200a continuously supplies hot air, the amount of hot air between the roller brush cover 130 and the roller brush 120 gradually increases. The water distribution structure 150 can thus evenly distribute the air. Due to the obstruction of the water distribution structure 150, the hot air cannot continue to flow upwards along the outer periphery of the roller brush 120, and the hot air will accumulate in the area near the water distribution structure 150. Hot air can flow along the extension direction of the water distribution structure 150 and dry the bristles of the roller brush 120 along the extension direction of the water distribution structure 150. This can more effectively improve the drying uniformity and drying efficiency of the roller brush 120, avoid the phenomenon of local dampness leading to bacterial growth or odor, and also reduce the possibility of watermarks on the surface to be cleaned due to local dampness of the roller brush 120.
[0124] See also some of the possible implementation methods. Figure 4 As shown, after the bottom of the front scraper 140 of this application embodiment is attached to the placement platform 210, the roller brush cover plate 130, the front scraper 140, at least part of the placement platform 210 and the floor brush body 110 can form a closed and sealed structure along the circumference of the roller brush 120.
[0125] In this embodiment, when the roller brush 120 rotates, dirt and liquid on the roller brush 120 are thrown towards the outer periphery of the roller brush 120 under the action of centrifugal force. For example, dirt is thrown out along the tangential direction of the roller brush 120. When the roller brush cover plate 130 is controlled to flip downward so that the bottom of the front scraper 140 is in contact with the placement platform 210, the circumferential space of the roller brush 120 can be sealed by the roller brush cover plate 130, the front scraper 140, at least part of the placement platform 210 and the floor brush body 110, so that dirt can be blocked in the closed sealing structure and is not easily thrown out in other directions, which helps to avoid secondary pollution caused by dirt being thrown out.
[0126] This application provides a cleaning device 10. See also... Figures 1 to 4 As shown, the cleaning device 10 of this application embodiment includes a floor brush assembly 100 and a base 200.
[0127] The floor brush assembly 100 of this application embodiment may include a floor brush body 110, a roller brush 120, a roller brush cover plate 130, a drive unit, and a control module.
[0128] The roller brush 120 is rotatably connected to the floor brush body 110. The surface to be cleaned can be cleaned by rotating the roller brush 120. A roller brush cover 130 is disposed on the floor brush body 110. Along the travel direction X of the floor brush body 110, a front scraper 140 is provided at the end of the roller brush cover 130 located in front of the roller brush 120. The roller brush cover 130 is flipped relative to the floor brush body 110, causing the front scraper 140 to move upwards or downwards.
[0129] The drive unit is located on the brush body 110. The drive unit can be used to drive the roller brush cover 130 to rotate. The control module is connected to the drive unit to control the drive unit to drive the roller brush cover 130 to rotate.
[0130] The base 200 has a placement platform 210 for placing the floor brush assembly 100. When the floor brush assembly 100 is placed on the base 200, the floor brush assembly 100 has a self-cleaning mode and a drying mode.
[0131] When the floor brush assembly 100 is in self-cleaning mode, the control module controls the roller brush cover 130 to flip downwards so that the bottom of the front scraper 140 fits against the placement table 210. When the floor brush assembly 100 is in drying mode, the control module controls the roller brush cover 130 to flip upwards so that there is a gap t1 between the bottom of the front scraper 140 and the placement table 210, allowing hot air to be blown onto the roller brush 120.
[0132] In this embodiment, in self-cleaning mode, the front scraper 140 can be in contact with the placement platform 210. There is no gap t1 between the front scraper 140 and the placement platform 210. Therefore, the dirt rolled up during the rotation of the roller brush 120 can be prevented from being thrown onto the wall surface of the base 200 on the side of the front scraper 140 facing away from the roller brush 120 by the blocking effect of the front scraper 140 and part of the roller brush cover plate 130.
[0133] After the roller brush 120 has finished cleaning, the floor brush assembly 100 can be controlled to enter the drying mode to dry the roller brush 120, preventing it from being damp for a long time and thus avoiding bacterial growth or odor. In the drying mode, the roller brush cover 130 can be flipped upwards, and the bottom of the front scraper 140 can be moved away from the placement table 210, so that a gap t1 can be formed between the bottom of the front scraper 140 and the placement table 210. Hot air can then flow through this gap t1 to the roller brush 120 to dry it.
[0134] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, in the drying mode, along the traveling direction X of the floor brush body 110, the gap t1 corresponds to the air outlet 200a of the base 200, so that the hot air from the air outlet 200a is blown to the roller brush 120 through the gap t1.
[0135] In this embodiment, the base 200 is provided with an air outlet 200a. The air outlet 200a can be used to provide hot air. In drying mode, the roller brush cover 130 is flipped upward so that a gap t1 is formed between the bottom of the front scraper 140 and the placement table 210. The hot air from the air outlet 200a can reach the roller brush 120 through the gap t1 by corresponding to the gap t1, and the roller brush 120 is dried.
[0136] See also some of the possible implementation methods. Figure 2 As shown, in the drying mode of this embodiment, the opening width of the air outlet 200a is less than or equal to the gap t1 between the front scraper 140 and the placement table 210.
[0137] In this embodiment, by setting the opening width of the air outlet 200a to be less than or equal to the gap t1 between the front scraper 140 and the placement table 210, the hot air released from the air outlet 200a can enter the gap t1 between the front scraper 140 and the placement table 210 as much as possible or all of it, and be provided to the roller brush 120. This helps to reduce the loss of hot air.
[0138] In some examples, the width direction of the opening of the air outlet 200a may refer to the height direction of the floor brush assembly 100. The gap t1 between the front wiper 140 and the placement platform 210 may refer to the gap t1 between the front wiper 140 and the placement platform 210 along the height direction of the floor brush assembly 100.
[0139] When the hot air at the air outlet 200a flows toward the roller brush 120, it tends to rise due to its lower density. By setting the opening width of the air outlet 200a to be less than or equal to the gap t1 between the front scraper 140 and the placement platform 210, the hot air flowing upward at the air outlet 200a can also easily enter the roller brush 120 through the gap t1, thereby improving the utilization rate of hot air and allowing more hot air to act on the roller brush 120, which helps to reduce the loss of hot air.
[0140] See also some of the possible implementation methods. Figure 2 As shown, in the drying mode, there is a radial gap between the roller brush cover plate 130 and the roller brush 120. A seal 160 is provided within the gap. The seal 160 extends axially along the roller brush 120. Along the circumference of the roller brush 120, the seal 160 is close to the floor brush body 110 to seal the area near the floor brush body 110.
[0141] In this embodiment, during the drying mode, the roller brush cover 130 is flipped upwards, and there is a radial distance between the inner wall of the roller brush cover 130 and the roller brush 120. During rotation, the roller brush 120 easily picks up liquids and dirt. These liquids and dirt can easily clog the distance between the roller brush cover 130 and the roller brush 120, affecting the rotation of the roller brush 120. In particular, the distance between the inner wall of the roller brush cover 130 and the roller brush 120 is smaller in the area near the brush body 110, making it easier for dirt to accumulate in this area, further affecting the rotation of the roller brush 120. Therefore, by providing a seal 160 close to the brush body 110, this distance near the brush body 110 can be sealed, thereby more effectively reducing the possibility of dirt clogging the distance and preventing the roller brush 120 from rotating.
[0142] See also some of the possible implementation methods. Figure 2 As shown, in the drying mode, an airflow guiding channel 100a can be formed between the inner wall of the roller brush cover plate 130 and the roller brush 120, so that part of the hot air provided by the air outlet 200a flows upward along the outer periphery of the roller brush 120.
[0143] In this embodiment, the hot air provided by the air outlet 200a of the base 200 can be blown towards the roller brush 120 through the gap t1 between the bottom of the front scraper 140 and the placement table 210. The hot air has a certain flow velocity. When the hot air contacts the outer peripheral surface of the roller brush 120, the hot air can be split into two sets of airflows along the shape of the roller brush 120. One set of airflows can flow into the space between the roller brush 120 and the placement table 210, and the other set of airflows can flow upward along the outer periphery of the roller brush 120 and enter between the roller brush 120 and the inner wall of the roller brush cover plate 130, so that along the height direction of the floor brush assembly 100, the hot air can dry the upper and lower areas of the roller brush 120. As the roller brush 120 rotates, the hot air can be more evenly distributed on the outer periphery of the roller brush 120 to improve the drying uniformity of the roller brush 120 and improve the drying effect of the roller brush 120.
[0144] Specifically, as hot air rises along the outer periphery of the roller brush 120, its lower density causes it to flow upwards easily. The roller brush cover 130 prevents the hot air from flowing away from the roller brush 120. In other words, the roller brush cover 130 concentrates the hot air between itself and the roller brush 120, ensuring continuous contact between the hot air and the bristles of the roller brush 120, thereby improving the utilization rate of the hot air and reducing heat loss.
[0145] Furthermore, it is easy to understand that as hot air flows away from the air outlet 200a of the base 200, its temperature gradually decreases, affecting the drying effect. The roller brush cover 130 can concentrate the hot air between the roller brush cover 130 and the roller brush 120. This concentration of hot air slows down the rate of temperature decrease, thereby improving drying efficiency.
[0146] Furthermore, since the seal 160 is located between the inner wall of the brush cover 130 and the brush 120, and extends axially along the brush 120, the seal 160 can block the flow of hot air towards the brush assembly 100, allowing the hot air to accumulate between the brush cover 130 and the brush 120. As the air outlet 200a continuously supplies hot air, the amount of hot air between the brush cover 130 and the brush 120 gradually increases. The seal 160 can also provide uniform airflow. Due to the obstruction of the seal 160, the hot air cannot continue to flow upwards along the outer periphery of the brush 120, and the hot air will accumulate in the area near the seal 160. Hot air can flow along the extension direction of the seal 160 and dry the bristles of the roller brush 120 along the extension direction of the seal 160, so as to more effectively improve the drying effect and drying efficiency of the roller brush 120, avoid the phenomenon of local dampness leading to bacterial growth or odor, and also reduce the possibility of watermarks on the surface to be cleaned due to local dampness of the roller brush 120.
[0147] It should be noted that when the local brush host is in self-cleaning mode, the seal 160 can also be used as the water distribution structure 150. The seal 160 provides squeezing force to the roller brush 120. On the one hand, it can make the liquid sprayed on the roller brush 120 by the water distributor more even, thereby improving the drying efficiency. On the other hand, it can squeeze out the dirt deep in the roller brush 120 along with the liquid, thereby improving the cleanliness of the roller brush 120 and improving the cleaning effect on the surface to be cleaned.
[0148] Furthermore, in self-cleaning mode, the roller brush 120 can clean the inner walls of both the roller brush 120 and the roller brush cover 130. After self-cleaning, moisture remains on the inner walls of the roller brush 120 and the roller brush cover 130. In drying mode, hot air flows within the airflow guide channel 100a between the inner wall of the roller brush cover 130 and the roller brush 120. While drying the roller brush 120, the hot air can also dry the inner wall of the roller brush cover 130, reducing the possibility that residual moisture on the inner wall of the roller brush cover 130 might flow onto the surface to be cleaned, thus affecting the cleaning effect.
[0149] In some examples, during the drying mode, the roller brush cover 130 is flipped upwards. The roller brush cover 130 and the roller brush 120 have a radial spacing to serve as an airflow guide channel 100a.
[0150] See some possible implementation methods. Figure 2 As shown, in the drying mode, the airflow guide channel 100a has a narrow throat region 100b. Along the flow direction of hot air within the airflow guide channel 100a, the narrow throat region 100b is close to the front scraper 140.
[0151] In this embodiment, by setting a narrow throat region 100b in the area of the airflow guide channel 100a near the front scraper 140, the hot air can reach a higher flow rate in the narrow throat region 100b. As the hot air leaves the narrow throat region 100b and continues to flow along the airflow guide channel 100a, the flow rate of the hot air can continue to increase, thereby accelerating the rate of moisture evaporation on the surface of the roller brush 120 and improving the drying efficiency of the roller brush 120.
[0152] Specifically, after hot air enters the gap t1 between the bottom of the front scraper 140 and the placement table 210 through the air outlet 200a, the hot air can first enter the narrow throat region 100b. Compared to the opening width of the gap t1 between the bottom of the front scraper 140 and the placement table 210, the opening width of the narrow throat region 100b is smaller; therefore, the flow velocity of the hot air in the narrow throat region 100b increases. As the airflow continues to flow upward along the airflow channel from the narrow throat region 100b, the opening width of the airflow guide channel 100a can increase, and the resistance of the airflow guide channel 100a to the hot air gradually decreases, allowing the flow velocity of the hot air to continue to increase, thereby improving the drying efficiency of the roller brush 120.
[0153] In some examples, during the drying mode, the opening width of the narrow throat region 100b within the airflow guide channel 100a can be minimized, and the opening width of the narrow throat region 100b can be less than the gap t1 between the front scraper 140 and the placement table 210.
[0154] See also some of the possible implementation methods. Figure 2 , Figure 5 and Figure 6 As shown, along the height direction of the floor brush assembly 100, the base 200 is provided with a shield 220 opposite to the placement platform 210. In drying mode, the front scraper 140 flips upward and abuts against the shield 220.
[0155] In this embodiment, the shield 220 can have a sealing function in the drying mode. The front scraper 140 abuts against the shield 220, allowing them to fit together to prevent hot air from easily escaping to the outside of the base 200, thereby reducing heat loss. This allows more of the hot air from the outlet 200a to act on the roller brush 120, improving the drying efficiency of the roller brush 120.
[0156] In some examples, the shield 220 may be formed of a flexible material so that the contact between the shield 220 and the roller brush cover 130 does not impede the movement of the brush assembly 100 when it leaves the placement table 210. The shield 220 may deform so that the roller brush cover 130 can separate from the shield 220, allowing the brush assembly 100 to be removed from the placement table 210. Once the brush assembly 100 has been removed from the placement table 210, the shield 220 may return to its original shape.
[0157] Furthermore, the floor brush assembly 100 has weight, and because the shielding member 220 can deform, when the floor brush assembly 100 is placed in the base 200 in drying mode, the front scraper 140 and the roller brush cover 130 can cause the shielding member 220 to deform so that it can enter the placement table 210. When the floor brush assembly 100 is placed on the placement table 210, the outer wall of the roller brush cover 130 can abut against the shielding member 220.
[0158] In some examples, the shield 220 may surround at least a portion of the opening at the upper end of the base 200. The shield 220 may extend toward the roller brush cover 130.
[0159] The shield 220 can be tilted downward from the edge of the opening toward the roller brush cover 130 to facilitate the brush assembly 100 entering the placement platform 210 of the base 200.
[0160] In some examples, the thickness of the shield 220 near the edge of the opening can be greater than the thickness of the shield 220 near the roller brush cover 130.
[0161] For example, see Figure 2 As shown, the shield 220 can be tilted downwards at a first angle from the edge of the opening towards the roller brush cover 130, and then tilted downwards at a second angle. The second angle can be greater than the first angle. The second angle can be used to guide the roller brush cover 130 when the floor brush assembly 100 is lowered into the placement platform 210.
[0162] Or see Figure 5 As shown, the shield 220 can slope downwards linearly from the edge of the opening towards the roller brush cover 130. Furthermore, see... Figure 6 As shown, after the shielding member 220 tilts downward at a first angle from the edge of the opening toward the roller brush cover plate 130, it can bend downward by a certain arc. No specific limitations are made in this embodiment.
[0163] See also some of the possible implementation methods. Figure 2As shown, along the traveling direction X of the floor brush assembly 100, the orthographic projection of the interval t2 between the inner wall of the base 200 and the front scraper 140 in the height direction of the floor brush assembly 100 is located inside the orthographic projection of the shield 220 in the height direction of the floor brush assembly 100.
[0164] In this embodiment, along the traveling direction X of the floor brush assembly 100, there is a gap t2 between the inner wall of the base 200 and the front scraper 140. This gap t2 can provide movement space for the flipping movement of the roller brush cover 130, avoiding collision between the roller brush cover 130 and the inner wall of the base 200. When the hot air provided by the air outlet 200a blows towards the roller brush 120, since hot air tends to flow upward, by setting a shield 220 corresponding to the upper part of the gap t2, the shield 220 can block the release of hot air to the outside of the base 200, thereby reducing the loss of hot air and allowing more hot air to act on the roller brush 120, which is beneficial to the drying efficiency of the roller brush 120.
