Description

Technical Field

[0001] This invention belongs to the field of cleaning technology, specifically relating to a roller brush assembly, a cleaning device, and a cleaning equipment. Background Technology

[0002] Cleaning equipment, such as floor scrubbers, is increasingly used for household floor cleaning due to its advantages, including ease of use and effective cleaning. A floor scrubber typically consists of a cleaning unit and a main unit. The cleaning unit moves across the surface to be cleaned, while the main unit creates negative pressure within the cleaning unit to draw dirt into it. The cleaning unit includes a suction channel, and the main unit's wastewater tank or dustbin is connected to the suction channel.

[0003] As users demand higher cleaning efficiency from floor scrubbers, dual-brush cleaning devices have emerged. These devices feature two brushes; during cleaning, the brush at the front of the moving direction cleans the surface once, while the brush at the rear of the moving direction performs a second cleaning, thus improving cleaning efficiency. Correspondingly, the device has separate inlet channels connected to each brush. These channels are also connected to suction channels, allowing each brush to draw dirt from the surface into its corresponding inlet channel during operation.

[0004] After prolonged use, the inlet channel of a floor scrubber needs to be cleaned to prevent dirt from accumulating and affecting cleaning performance. In existing technology, cleaning the inlet channel requires first removing the top cover of the cleaning device, then removing the roller brush to expose the inlet channel before cleaning can begin. This process is cumbersome and inconvenient. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is how to quickly and conveniently clean the inlet channel of the cleaning device of the cleaning equipment.

[0009] The housing has a first sludge inlet channel with a first sludge inlet, and the roller brush is disposed near the first sludge inlet. The cover is installed on the housing to form a suction port communicating with the first sludge inlet. The cover is detached from the housing to expose at least a portion of the suction port for cleaning.

[0010] Optionally, in the above-described roller brush assembly, the housing has a first sidewall abutting against the roller brush and a second sidewall connected to the first sidewall and facing the roller brush.

[0011] The cover has an inner wall facing the housing, and the inner wall, the first side wall and the second side wall surround to form the suction port;

[0012] When the cover is disassembled from the housing, all of the suction ports are exposed.

[0013] Optionally, in the above-described roller brush assembly, the outlet of the suction port serves as the first sewage inlet.

[0014] Optionally, in the above-described roller brush assembly, the housing further includes a first guide member connected to the second sidewall;

[0015] The first guide member is inclined toward the first inlet from the side away from the first inlet to the side closer to the first inlet, and is adapted to guide the dirt that falls into the suction port to the first inlet.

[0016] Optionally, in the above-described roller brush assembly, the cover includes a connecting portion connected to the housing and a bent portion that bends from one end of the connecting portion toward the roller brush, wherein the connecting portion and the bent portion form the suction port;

[0017] When the cover is detached from the housing, the suction port is detached along with the cover from the first sewage inlet, so that the first sewage inlet and part of the suction port are exposed.

[0018] Optionally, in the above-mentioned roller brush assembly, the connecting part is provided with a slot communicating with the suction port, and the cover further includes a transparent body disposed at the slot and detachably connected to the slot, the transparent body being adapted to make the interior of the suction port visible.

[0019] When the transparent body is detached from the slot, the suction port is exposed.

[0020] Optionally, in the roller brush assembly described above, the first inlet is inclined from bottom to top toward the roller brush in the height direction of the housing, so that the first inlet is exposed when the cover is disassembled from the housing.

[0021] Optionally, in the above-mentioned roller brush assembly, a scraper and a second guide are provided at the suction port; one end of the scraper is connected to the upper end of the suction port and abuts against the roller brush, which is suitable for hanging the dirt on the roller brush.

[0022] One end of the second guide is connected to the lower end of the suction port and is inclined toward the roller brush, which is suitable for guiding the fallen dirt into the connecting channel.

[0023] The present invention also provides a cleaning device, comprising:

[0024] The housing has a suction channel, a first inlet channel and a second inlet channel that are respectively connected to the suction channel;

[0025] A roller brush assembly is connected to the housing, and the roller brush assembly is positioned near the first sewage inlet of the first sewage inlet channel.

[0026] The cleaning component is rotatably connected to the housing and is adapted to clean the surface to be cleaned; the cleaning component is located near the second inlet of the second dirt inlet channel, with the moving direction of the cleaning device as the front, and the cleaning component is located in front of the roller brush assembly;

[0027] The roller brush assembly is the roller brush assembly described above.

[0028] Optionally, in the above-mentioned cleaning device, the suction channel is arranged perpendicular to the first direction, which is the moving direction of the cleaning device;

[0029] The first sewage inlet channel is positioned parallel to the first direction and is located above the second sewage inlet channel.

[0030] Optionally, in the cleaning device described above, the first sewage inlet channel includes a bent section and a smooth section, wherein the bent section is connected to one end of the first sewage inlet and one end of the smooth section, so as to guide the airflow of the first sewage inlet to the smooth section;

[0031] The other end of the smooth section is connected to the second sewage inlet channel, and the outlet of the smooth section is flush with the second sewage inlet to prevent the airflow flowing out of the outlet of the smooth section from colliding with the airflow entering the second sewage inlet channel from the second sewage inlet.

[0032] Optionally, in the cleaning device described above, the size of the first sewage inlet is smaller than the size of the second sewage outlet of the second sewage inlet channel, so that the airflow rate from the second sewage outlet into the sewage suction channel is greater than the airflow rate from the first sewage inlet into the sewage suction channel.

[0033] Optionally, in the cleaning device described above, the second inlet is located below the first inlet in the height direction of the housing.

[0056] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0057] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0058] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0059] Example 1

[0060] Please combine Figure 1 This embodiment provides a roller brush assembly 10, which is suitable for installation with the cleaning device 100 of a cleaning equipment to perform corresponding cleaning actions on the surface to be cleaned, thereby achieving a cleaning effect. The surface to be cleaned can be a floor, wall, or the surface of an object to be cleaned, and this application does not specifically limit the type of surface to be cleaned.

[0061] The cleaning actions described above can be vacuuming, mopping, or both, to ensure the cleaning efficiency of the cleaning equipment. In this embodiment, the cleaning actions are primarily performed simultaneously with vacuuming and mopping.

[0062] Specifically, the roller brush assembly 10 includes a roller brush 102, which rotates under the drive of a drive motor to clean the surface to be cleaned. Therefore, the roller brush 102 is rotatably connected to the housing 1 of the cleaning device 100.

[0063] The connection between the drive motor and the roller brush 102 can be as follows: the drive motor is located on one side of the roller brush 102 and connected to the roller brush 102 via a transmission component. This transmission component can be a gear and rack drive, a conventional transmission structure, which will not be elaborated upon here. However, this arrangement results in the roller brush 102 occupying a larger volume in the housing 1. To facilitate the arrangement of other components, the overall volume of the housing 1 will increase, thus increasing the overall size of the cleaning device 100.

[0064] Therefore, in this embodiment, the connection between the drive motor and the roller brush 102 is as follows: the roller brush 102 is provided with an inner cavity, and the drive motor can be embedded in the inner cavity so that the drive motor and the roller brush 102 are coaxially arranged, thereby reducing the space occupied by the roller brush assembly 10 on the housing 1, so that the overall volume of the cleaning device 100 is smaller and the overall cleaning device 100 is more compact.

[0065] The roller brush assembly 10 also includes a cover 101 detachably connected to the housing 1. The cover 101 is located above the roller brush 102 to cover at least a portion of the roller brush 102. The purpose of providing the cover 101 is that when the roller brush 102 rotates under the drive of the drive motor, at least some of the dirt on the surface to be cleaned will be splashed to various places under the centrifugal force generated by the rotating roller brush 102, causing secondary cleaning of the surface to be cleaned and cleaning of other places, thus reducing cleaning efficiency. The cover 101 can effectively cover the splashed dirt, thereby preventing further splashing of dirt and ensuring the cleaning efficiency of the cleaning device 100 and the cleaning equipment.

[0066] In this embodiment, the cover 101 is arc-shaped, with one end connected to the housing 1 and the other end extending along the outer circumference of the roller brush 102 toward the surface to be cleaned, thereby effectively blocking at least part of the roller brush 102 and preventing splashed dirt. It is worth noting that there is a gap between the other end of the housing 1 and the surface to be cleaned, thus avoiding friction between the cover 101 and the surface during cleaning, which would reduce cleaning efficiency.

[0067] Please combine Figure 2 and Figure 3 , or combination Figure 4 and Figure 5 The cleaning device 100 has a housing 1 with a first dirt inlet channel 11 and a first dirt inlet 111. A roller brush 102 is positioned near the first dirt inlet 111. When the roller brush 102 rotates to clean the surface to be cleaned, dirt on the surface will enter the first dirt inlet channel 11 from the first dirt inlet 111 under the action of the roller brush 102, thereby cleaning the surface to be cleaned.

[0068] As described above, the cover 101 and the housing 1 are detachably installed. The cover 101 and housing 1 are installed to form a suction port 15 communicating with the first dirt inlet 111. This suction port 15 allows dirt from the roller brush 102 during cleaning to first enter the suction port 15, and then through the suction port 15 and the first dirt inlet 111 into the first dirt inlet channel 11. The cover 101 and housing 1 can be detached to expose at least a portion of the suction port 15, facilitating cleaning by the user.

[0069] Please combine Figure 2 and Figure 3 In one embodiment, the housing 1 has a first sidewall abutting against the roller brush 102 and a second sidewall connected to the first sidewall and facing the roller brush 102. The cover 101 has an inner wall 103 facing the housing 1. The inner wall 103, the first sidewall, and the second sidewall form a suction port 15. The inlet of the suction port 15 is located close to the roller brush 102 so that dirt can enter the suction port 15 from the inlet. The outlet of the suction port 15 serves as a first dirt inlet 111 so that dirt entering the suction port 15 can enter the first dirt inlet channel 11 through the first dirt inlet 111.

[0070] When the cover 101 is disassembled from the housing 1, all suction ports 15 are exposed. Specifically, the inner wall 103, the first side wall, and the second side wall forming the suction port 15 are all exposed. Therefore, the user can clean the exposed inner wall 103, the first side wall, and the second side wall to prevent dirt from remaining in the suction port 15 and causing low cleaning efficiency.

[0071] Furthermore, users can insert auxiliary cleaning components (such as cleaning brushes) into the first dirt inlet 111 through the first dirt inlet 111 to effectively clean the dirt remaining in the first dirt inlet 11, thereby preventing the accumulation of residual dirt in the first dirt inlet 11 and affecting the entry of dirt into the first dirt inlet 11 in other cleaning sessions, thus improving the cleaning efficiency of the cleaning device 100.

[0072] In this embodiment, in order to enable the dirt entering the suction port 15 to enter the first dirt inlet channel 11 better from the first dirt inlet 111, the housing 1 also includes a first guide 14 connected to the second side wall. The first guide 14 is adapted to guide the dirt entering the suction port 15 to the first dirt inlet 111.

[0073] Specifically, the first guide member 14 is inclined toward the first inlet 111 from the side away from the first inlet 111 to the side closer to the first inlet 111, suitable for guiding the dirt that falls into the suction port 15 to the first inlet 111. The cross-section of the first guide member 14 along the horizontal plane is triangular, that is, the first guide member 14 is a triangular prism. The triangular prism has a first right-angled face, a second right-angled face, and an inclined face. The first right-angled face and the second right-angled face are connected to the first sidewall and the second sidewall, respectively, and the inclined face serves as a guide surface to guide the dirt.

[0074] In this embodiment, two first guide members 14 are provided, and the two first guide members 14 are respectively provided on both sides of the first sewage inlet 111, which is suitable for guiding the sewage on both sides of the first sewage inlet 111 to the first sewage inlet 111.

[0075] In order to simplify the manufacturing process and prevent gaps from existing between the first guide member 14 and the first and second sidewalls so that dirt can enter the gaps, the first guide member 14 is integrally formed with the housing 1.

[0076] Please combine Figure 4 and Figure 5 In another embodiment, the cover 101 includes a connecting portion connected to the housing 1 and a bent portion that bends from one end of the connecting portion toward the roller brush 102. There is a gap between the inner surface of the bent portion and the inner surface of the connecting portion, thereby forming a suction port 15 between the connecting portion and the bent portion.

[0077] When the cover 101 is disassembled from the housing 1, the suction port 15 is also disassembled along with the cover 101 and the first sewage inlet 111, so that the first sewage inlet 111 and part of the suction port 15 are exposed. Correspondingly, when the cover 101 is installed with the housing 1, the suction port 15 is installed along with the cover 101 and the first sewage inlet 111.

[0078] Specifically, in this embodiment, the inlet of the suction port 15 is positioned close to the roller brush 102 so that when the roller brush 102 cleans the surface to be cleaned, dirt can enter the suction port 15 from the inlet. Furthermore, the outlet of the suction port 15 is positioned opposite to the first dirt inlet 111, so that dirt entering the suction port 15 can directly enter the first dirt inlet channel 11 from the outlet of the suction port 15 through the first dirt inlet 111, thereby completing the cleaning of the surface to be cleaned.

[0079] To facilitate cleaning of the suction port 15, the connecting part is provided with a slot 105 communicating with the suction port 15. The cover 101 also includes a transparent body 104 disposed at and detachably connected to the slot 105. The transparent body 104 is adapted to make the interior of the suction port 15 visible, thereby facilitating the user to observe the dirt inside the suction port 15. Furthermore, when the transparent body 104 is detached from the slot 105, the suction port 15 is exposed. In this embodiment, the transparent body 104 can be transparent glass or transparent plastic, etc.

[0080] That is, when the user observes through the transparent body 104 that the inside of the suction port 15 is dirty, the transparent body 104 can be disassembled from the groove 105, and an auxiliary cleaning component (such as a cleaning brush) can be inserted into the suction port 15 through the groove 105 to clean the inside of the suction port 15. Alternatively, an auxiliary cleaning component can be inserted into the suction port 15 through the outlet to clean the suction port 15. Similarly, the user can also insert an auxiliary cleaning component into the first dirt inlet 111 through the first dirt inlet channel 11 to clean the first dirt inlet channel 11, etc.

[0081] To facilitate cleaning of the first inlet 111 and the first inlet channel 11, the first inlet 111 is inclined upwards towards the roller brush 102 along the height direction of the housing 1 (as shown by arrow a in the figure), so that the first inlet 111 is exposed when the cover 101 is disassembled from the housing 1. Furthermore, when the first inlet 111 is exposed, its inclined arrangement makes it easier for the user to insert auxiliary cleaning components into the first inlet channel 11 through the first inlet 111 to clean the first inlet channel 11.

[0082] A scraper 3 and a second guide 4 are provided at the suction port 15. One end of the scraper 3 is connected to the upper end of the suction port 15 and abuts against the roller brush 102, suitable for hanging off the dirt on the roller brush 102. One end of the second guide 4 is connected to the lower end of the suction port 15 and is inclined towards the roller brush 102, suitable for guiding the fallen dirt into the connecting channel. Specifically, one end of the scraper 3 is connected to the upper end of the inlet of the suction port 15, and one end of the second guide 4 is connected to the lower end of the inlet of the suction port 15. With the above arrangement, the dirt attached to the roller brush 102 can be hung off, and when the hung dirt falls downward under its own gravity, it will be guided into the suction port 15 by the second guide 4 located below the scraper 3.

[0083] In summary: By installing the cover 101 and the housing 1 to form a suction port 15, at least part of the suction port 15 can be exposed when the cover 101 and the housing 1 are disassembled. This eliminates the need to disassemble the cover 101 and the roller brush 102 in sequence, allowing the user to directly clean the exposed suction port 15. This improves the cleaning efficiency of the suction port 15 and the first sewage inlet channel 11, as well as the overall cleaning efficiency of the cleaning device 100 and the cleaning equipment.

[0084] Example 2

[0085] Please combine Figure 1 This embodiment provides a cleaning device 100, adapted to move along a surface to be cleaned under the action of an external force to clean the surface. The external force can be human force, meaning a user can operate the cleaning device 100 and thus drive it to move. Alternatively, the external force can be mechanical force, meaning the cleaning device 100 can move under the drive of other driving mechanisms.

[0086] The cleaning device 100 is installed with the main unit, which is adapted to generate negative pressure within the cleaning device 100, so that dirt on the surface to be cleaned can enter the cleaning device 100 under the action of negative pressure, thereby completing the cleaning of the surface to be cleaned. This negative pressure is the suction force of the cleaning device 100, which is adapted to suck the dirt on the surface to be cleaned into the cleaning device 100.

[0087] To ensure the cleaning efficiency of the cleaning device 100, in this embodiment, the cleaning device 100 includes a housing 1, a roller brush assembly 10 connected to the housing 1, and a cleaning assembly 2 rotatably connected to the housing 1. That is, in this embodiment, the cleaning device 100 is a cleaning device 100 with dual roller brushes. The roller brush assembly 10 is the same as the roller brush assembly 10 in Embodiment 1 above, and the cleaning assembly 2 includes the same cleaning component as the roller brush 102 in the roller brush assembly 10.

[0088] With the direction of movement of the cleaning device 100 as forward (indicated by arrow b in the figure), the cleaning component 2 is located in front of the roller brush assembly 10. Similarly, in order to ensure the cleaning efficiency of the cleaning device 100 and to prevent dirt from splashing under centrifugal force during the rotation of the cleaning component 2, the housing 1 includes an upper cover portion, which is disposed above the cleaning component 2 to cover at least part of the cleaning component 2.

[0089] The housing 1 also includes a suction channel 13, a first inlet channel 11 and a second inlet channel 12 respectively connected to the suction channel 13. A roller brush assembly 10 is positioned near the first inlet port 111 of the first inlet channel 11, and a cleaning assembly 2 is positioned near the second inlet port 121 of the second inlet channel 12. When the cleaning device 100 cleans the surface to be cleaned, the cleaning assembly 2, located at the front, performs a first cleaning of the surface. The roller brush assembly 10, located at the rear, then performs a second cleaning of the surface, thereby improving the cleaning efficiency.

[0090] Alternatively, when the user drives the cleaning device 100 to move in the opposite direction to its movement, a secondary cleaning of the surface to be cleaned can also be achieved. That is, the roller brush assembly 10 first cleans the surface to be cleaned, and then the cleaning assembly 2 performs a secondary cleaning, thereby ensuring the cleaning efficiency of the cleaning device 100.

[0091] However, in actual use, users typically operate with the cleaning component 2 primarily cleaning the surface to be cleaned, while the roller brush component 10 serves as a supplementary cleaning agent. That is, during the operation of the cleaning device 100, the cleaning component 2 performs primary cleaning of the surface more frequently than the roller brush component 10. Therefore, to ensure the cleaning efficiency of the cleaning device 100 and reduce power consumption to increase overall battery life, the suction power of the cleaning device 100 needs to be rationally distributed.

[0092] The conventional method is to have equal suction power at the cleaning component 2 and at the roller brush component 10. However, as mentioned above, the cleaning component 2 is actually used for primary cleaning, while the roller brush component 10 is used for auxiliary cleaning. Therefore, in this embodiment, the suction power at the cleaning component 2 is greater than the suction power at the roller brush component 10.

[0093] Please combine Figure 6 , or please combine Figures 7 to 9The suction force is closely related to the first inlet 111 of the first inlet channel 11 and the second outlet of the second inlet channel 12. Specifically, in this embodiment, the size of the first inlet 111 is smaller than the size of the second outlet of the second inlet channel 12, so that the airflow rate from the second outlet into the suction channel 13 is greater than the airflow rate from the first inlet 111 into the suction channel 13.

[0094] As mentioned above, the suction force at the roller brush assembly 10 is less than that at the cleaning assembly 2. The reduced suction force may lead to a decrease in the cleaning efficiency of the roller brush assembly 10 located at the rear. In order to ensure the cleaning efficiency of the roller brush assembly 10, the second dirt inlet 121 is located below the first dirt inlet 111 in the height direction of the housing 1.

[0095] Similarly, the suction port 15 is also positioned at a high position along with the first dirt inlet 111. By positioning the second dirt inlet 121 at a high position, dirt can be rotated to a high position as the roller brush 102 rotates. The scraper 3 located at the suction port 15 can scrape the dirt off the roller brush 102, and the scraped dirt is then guided to the first dirt inlet 111 by the second guide 4 located at the suction port 15, thereby effectively ensuring the cleaning efficiency of the roller brush assembly 10.

[0096] Please combine Figure 6 Furthermore, to ensure the cleaning efficiency of the cleaning device 100 and prevent the airflow entering the first inlet channel 11 and the airflow entering the second inlet channel 12 from clashing and reducing suction power, in one embodiment, the suction channel 13 is arranged perpendicular to a first direction, which is the direction of movement of the cleaning device 100; the first inlet channel 11 is arranged parallel to the first direction and is located above the second inlet channel 12. By arranging the first inlet channel 11 above the second inlet channel 12 and arranging the first inlet channel 11 parallel to the first direction, the airflow entering the first inlet channel 11 can avoid clashing with the airflow in the second inlet channel 12 when flowing into the suction channel 13.

[0097] Meanwhile, in this embodiment, a guide is also provided at the first outlet of the first sewage inlet channel 11. The guide is inclined along the first direction, which is suitable for the airflow in the first sewage inlet channel 11 to flow to the inner wall of the sewage suction channel 13 when it flows out of the first outlet, instead of directly colliding with the airflow in the sewage suction channel 13, so as to achieve buffering.

[0098] Please combine Figures 7 to 9In another embodiment, the first sewage inlet channel 11 includes a bent section 112 and a smooth section 113. The bent section 112 is connected to one end of the first sewage inlet 111 and one end of the smooth section 113, respectively, to guide the airflow from the first sewage inlet 111 to the smooth section 113. The other end of the smooth section 113 is connected to the second sewage inlet channel 12, and the outlet of the smooth section 113 is flush with the second sewage inlet 121 to prevent the airflow flowing out of the outlet of the smooth section 113 from colliding with the airflow entering the second sewage inlet channel 12 from the second sewage inlet 121.

[0099] With the above settings, it is possible to effectively prevent the airflow in the first sewage inlet channel 11 and the airflow in the second sewage inlet channel 12 from colliding when entering the sewage suction channel 13, thereby ensuring the cleaning efficiency of the cleaning device 100.

[0100] Example 3

[0101] Please combine Figure 1 This embodiment provides a cleaning device, including a cleaning device 100 and a main unit.
