[0052] The following will take a handheld floor scrubber in a vertical state as an example, and the handheld floor scrubber moves from back to front:

[0053] Please combine Figure 4 The machine body 100 generally includes a handle assembly (not shown in the figure), a machine body (not shown in the figure) and a base. The handle assembly is connected to the upper part of the machine body, and the base is connected to the lower part of the machine body. The machine body is generally detachably connected with a clean water tank and its related waterway structure, a cleaning liquid tank and its related waterway system, a sewage tank and its related waterway system, a main drive device, a main control device and other functional components.

[0054] The base generally includes a shell, and the shell forms a mounting cavity 110 at least in the lower area of ​​the base, and the mounting cavity 110 is provided with a first opening 111 that penetrates to the bottom of the shell. The cleaning module 200 is partially accommodated in the mounting cavity 110, and partially extends downwardly from the mounting cavity 110 through the first opening 111, so as to be able to contact the surface to be cleaned passing under the base to perform a cleaning action.

[0055] The housing is generally further formed with a sewage collecting channel 120, which is connected to the installation cavity 110 through a sewage suction port 130. The shape, size, and layout of the sewage collecting channel 120 are not limited. Figure 4 As shown, the dirt collection channel 120 is generally located above the installation cavity 110, and is bent upward and backward to extend in a longitudinal shape. The other end of the dirt collection channel 120 can be directly connected to the outside of the whole machine, for example, connected to a dirt collection box outside the whole machine through a pipeline; or the machine body or base is preset with a dust box, and the other end of the dirt collection channel 120 can be connected to the dust box, so that the dirt can be stored in the dust box.

[0056] When the whole machine is running, negative pressure is formed at least in the sewage collecting channel 120 and the sewage suction port 130.

[0057] The cleaning module 200 is mainly used to clean the surface to be cleaned. Figures 2 to 4 The utility model provides a cleaning module 200 applied to the above-mentioned cleaning device, the cleaning module 200 includes a first roller brush 210, a second roller brush 220 and a driving mechanism 230. The first roller brush 210 and the second roller brush 220 are sequentially arranged on the body 100 of the cleaning device along the walking direction of the cleaning device (i.e., from back to front), the first roller brush 210 and the second roller brush 220 are rotatable, and the rotation directions of the two are opposite, the rolling surface of the second roller brush 220 is convexly provided with elastically deformable ribs along its radial direction, and the ribs are arranged at intervals along the circumference of the second roller brush 220, each of which includes a first rib 221 with a longer protruding length and a second rib 222 with a shorter protruding length; the driving mechanism 230 is used to be arranged on the body 100, and drive the first roller brush 210 and the second roller brush 220 to rotate.

[0058] In the cleaning module 200 provided by the present invention, the rolling surface of the first roller brush 210 is not limited. For example, when the first roller brush 210 is a fluff roller brush, it can perform wet and dry cleaning on the surface to be cleaned; the second roller brush 220 is located at the front side of the first roller brush 210, and elastic ribs are convexly provided on the peripheral side of the second roller brush 220. When the ribs are rotated until they contact the surface to be cleaned, the ribs can perform edge cleaning on the surface to be cleaned through elastic deformation. Regardless of the particle size of the dirt on the surface to be cleaned, the dirt can be efficiently cleaned; it can also scrape off water stains when the first roller brush 210 leaves water stains on the surface to be cleaned , and picks up the wet hair on the surface to be cleaned to prevent the wet hair from being entangled in the first roller brush 210; the first rib 221 with a longer length has sufficient elastic deformation ability, which helps to increase the cleaning area adjacent to the surface to be cleaned; the second rib 222 with a shorter length has sufficient structural strength, which helps to improve the cleaning force adjacent to the surface to be cleaned; by arranging the first rib 221 and the second rib 222 alternately, the cleaning area and cleaning force adjacent to the surface to be cleaned by the second roller brush 220 can be balanced, thereby optimizing the cleaning effect of the surface to be cleaned as a whole and improving the use quality of the whole machine.

[0059] In this design, the cleaning module 200 is provided with at least two roller brushes, each of which is rotatably mounted on the wall of the mounting cavity 110 by, for example, a rotating shaft, and the rotational driving force of each roller brush is directly or indirectly provided by the driving mechanism 230. The two roller brushes are respectively a first roller brush 210 and a second roller brush 220:

[0060] The first roller brush 210 is located at the rear area of ​​the base and can be in the form of a fluff roller brush, a flannel roller brush, a soft roller brush, a rubber strip roller brush, etc.

[0061] The second roller brush 220 is located in the front area of ​​the base. The second roller brush 220 is configured as a rubber strip roller brush, that is, the rolling surface of the second roller brush 220 is convexly provided with a plurality of ribs, each of which extends along the axial direction and radial direction of the second roller brush 220, and all the ribs are arranged at intervals along the circumference of the second roller brush 220.

[0062] Agency Case Number:

[0063] Among them, the arrangement of each rib can be equidistant or non-equidistant; the corresponding size of each rib in the circumferential direction of the second roller brush 220, the corresponding size in the axial direction of the second roller brush 220, the specific material selection, the cross-sectional shape, etc. can be adjusted to be the same according to actual needs, or adjusted to be at least partially different.

[0064] The ribs are made of elastic and deformable materials, such as silicone, rubber, etc. In a further embodiment, Figures 2 to 4In one embodiment, the cleaning device has a bottom surface 141 for walking on the surface to be cleaned. For example, when the cleaning device walks on the surface to be cleaned by rolling the walking wheel 140, the wheel surface of the walking wheel 140 that is rollingly connected to the surface to be cleaned is generally at the bottom of the whole machine, forming the bottom surface 141 of the whole machine. Among them, the walking wheel 140 can be, for example, a one-way roller that can be rolled in a single direction, a multi-directional roller that can be rolled in at least two directions, or a universal wheel that can be rolled in all directions. Based on this, the distance between the rolling surface of the second rolling brush 220 and the bottom surface 141 is less than the protruding length of the first rib 221. In this way, when at least the first rib 221 of the ribs is driven by the second rolling brush 220 to rotate relative to the surface to be cleaned, it will produce elastic deformation under the influence of the rotation driving force and the interaction force between the ribs and the surface to be cleaned, so that the ribs are partially bent and fit the surface to be cleaned, so that the dirt on the surface to be cleaned at the corresponding position can be taken away.

[0065] Specifically, the radial length of the first rib 221 along the second roller brush 220 is greater than the radial length of the second rib 222 along the second roller brush 220. This means that when the rib is driven by the second roller brush 220 to rotate relative to the surface to be cleaned, the elastic deformation of the first rib 221 is generally greater than the elastic deformation of the second rib 222, so that the bending portion of the first rib 221 is larger and the area in contact with the surface to be cleaned is larger, thereby helping to increase the cleaning area adjacent to the surface to be cleaned.

[0066] In view of the above, when the distance between the rolling surface of the second rolling brush 220 and the bottom surface 141 is less than the protruding length of the second rib 222, the second rib 222 can act on the surface to be cleaned. The elastic deformation of the second rib 222 is generally less than the elastic deformation of the first rib 221, so that the interaction force between the second rib 222 and the surface to be cleaned cannot be consumed in large quantities by the elastic deformation of the second rib 222, and still acts between the second rib 222 and the surface to be cleaned, thereby helping to increase the edge cleaning force applied to the surface to be cleaned.

[0067] On the contrary, when the distance between the rolling surface of the second rolling brush 220 and the bottom surface 141 is greater than the protruding length of the second rib 222, the second rib 222 cannot directly act on the surface to be cleaned, that is, the second rolling brush 220 acts on the surface to be cleaned only through the first rib 221. At this time, the arrangement area of ​​the second rib 222 between every two adjacent first ribs 221 does not contact the surface to be cleaned, which is equivalent to reserving sufficient deformation space for the elastic deformation of the first rib 221 without interference, which helps the first rib 221 to achieve its edge cleaning purpose through a large degree of elastic deformation.

[0068] Based on any of the above embodiments, the elastic deformable material of the first rib 221 and the elastic deformable material of the second rib 222 can be set the same. In this case, the first rib 221, the second rib 222, and the peripheral side wall connecting the first rib 221 and the second rib 222 on the second roller brush 220 can be obtained by integrally forming the same material, which helps to simplify the molding process of the second roller brush 220. Of course, the elastic deformable material of the first rib 221 and the elastic deformable material of the second rib 222 can also be set differently. For example, by adjusting the specific selection of the elastic deformable material of the first rib 221 and / or the second rib 222, the elastic deformation performance, structural strength, elastic deformation direction and other parameters of the first rib 221 and / or the second rib 222 can be appropriately adjusted.

[0069] The diameter of the second roller brush 220 is smaller than or equal to the diameter of the first roller brush 210 .

[0070] In addition, please combine Figures 2 to 3 In one embodiment, at the side where the first roller brush 210 and the second roller brush 220 are close to each other, at least the first rib 221 extends toward the first roller brush 210 to movably abut against the rolling surface of the first roller brush 210. It can be understood that the first roller brush 210 and the second roller brush 220 are arranged side by side in the front-to-back direction and rotate respectively, so that the first roller brush 210 and the second roller brush 220 have a side close to each other (that is, located between the first roller brush 210 and the second roller brush 220), and a first side away from each other (that is, the rear side of the first roller brush 210 and the front side of the second roller brush 220). When on the side where the first roller brush 210 and the second roller brush 220 are close to each other, at least the first rib 221 is movably abutted against the rolling surface of the first roller brush 210. As the first roller brush 210 and the second roller brush 220 rotate, the first rib 221 and the rolling surface of the first roller brush 210 can be driven to interfere with each other, which is equivalent to the first rib 221 interfering with the rolling surface of the first roller brush 210 when passing through the rolling surface of the first roller brush 210 at the corresponding position. The interference can enable the first rib 221 to clean the rolling surface of the first roller brush 210, and clean out dirt such as water, impurities, hair, etc. remaining on the first roller brush 210, which helps to maintain the cleanliness of the first roller brush 210 as much as possible, and to a certain extent helps to improve the cleaning ability and cleaning effect of the first roller brush 210 on the surface to be cleaned.

[0071] Also, see Figure 2 and Figure 4In one embodiment, when the installation cavity 110 and the dirt collection channel 120 are connected through the dirt suction port 130 as described above, the cleaning device further includes a stopper 150, which is convexly arranged on the front side of the dirt suction port 130, and when the second roller brush 220 rotates and drives each of the ribs to pass through the stopper 150 in sequence, the stopper 150 at least slides and abuts against the first rib 221. When each rib moves through the stopper 150 and slides and abuts against the stopper 150, the stopper 150 and at least the first rib 221 of the second roller brush 220 interfere with each other, and the interference can make the stopper 150 clean at least the first rib 221, clean the residual dirt on at least the first rib 221 that is not sucked away by the dirt suction port 130, and clean out the dirt such as impurities, hair, etc. remaining on at least the first rib 221, which helps to keep the second roller brush 220 clean as much as possible. Furthermore, since the stopper 150 is disposed adjacent to the dirt suction port 130 , the dirt cleaned from the second roller brush 220 can be directly delivered to the dirt suction port 130 nearby, thereby preventing the dirt from remaining and accumulating in the installation cavity 110 .

[0072] Furthermore, in one embodiment, the stopper 150 is made of a hard material. The hard material is, for example, metal or wear-resistant plastic, which is not easily deformed when in contact with the ribs on the second roller brush 220 and has a certain structural agent.

[0073] The strength helps to improve the cleaning effect of the second roller brush 220.

[0074] The stopper 150 may extend longitudinally along the axial direction of the second roller brush 220 corresponding to each rib, so as to clean the entire rib at the same time. The stopper 150 may be integrally formed with the housing, or may be separately formed with the housing and detachably connected.

[0075] In addition, please combine Figures 2 to 3 In one embodiment, as described above, the installation cavity 110 is further provided with a second opening 112 at its front side; the cleaning device further comprises a front baffle 160 which at least partially covers the second opening 112, and when the second roller brush 220 rotates and drives each of the ribs to pass through the front baffle 160 in sequence, at least the first rib 221 slides and abuts against the inner side surface of the front baffle 160. The front baffle 160 is adapted to the moving track of each rib in the rotating state and extends in an arc shape, shielding the roller brush module in the front direction, reducing the dirt and water in the installation cavity 110 from being thrown forward; and can also limit the roller brush module from escaping from the installation cavity 110. The distance between the front baffle 160 and the rolling surface of the second roller brush 220 is at least not greater than the protruding length of the first convex rib, so that at least the first convex rib can slide and abut against the inner side surface of the front baffle 160 when rotating through the front baffle 160, which is equivalent to cleaning the inner side surface of the front baffle 160.

[0076] Furthermore, in one embodiment, the front baffle 160 is made of a flexible material. Specifically, the front baffle 160 is made of a soft wear-resistant material such as non-pick, soft silicone, and a hair-planted scraper strip, which can not only achieve the water-blocking function, but also make the contact between each rib and the front baffle 160 flexible, thereby avoiding collision noise when the two are in frequent contact, thereby reducing the quality of use of the whole machine.

[0077] Based on any of the above embodiments, in a further solution, at least the surface of the first rib 221 is provided with an interference protrusion 223. A plurality of interference protrusions 223 are dispersed on the first rib 221. The cross-sectional shape of the interference protrusion 223 is not limited, and may be circular, quasi-circular, elliptical, polygonal or a desired special shape; the outer surface of the interference protrusion 223 may be provided in an arc shape so as to be able to smoothly guide the contact between the surface to be cleaned, the rolling surface of the first rolling brush 210, the stopper 150 and the front baffle 160, etc. The interference protrusion 223 is arranged on at least the side wall of the first rib 221, and specifically is a side wall facing the surface to be cleaned, the rolling surface of the first rolling brush 210, the stopper 150 and the front baffle 160 during the process of the first rib 221 rotating and approaching. The arrangement of the interference protrusion 223 on the side wall of the first rib 221 is not limited, and may be arranged in an array, arranged in a radial shape, arranged in a vortex shape, arranged randomly, etc. The protruding heights of the interference protrusions 223 can be set the same, or can be set differently in different regions, so as to strengthen the interference amount in the local area, or weaken the interference amount.

[0078] Based on any of the above embodiments, the first roller brush 210 and the second roller brush 220 are respectively rotatably installed on the body 100, and the rotation directions of the two are opposite. In this way, it not only helps to achieve mutual cleaning between the first roller brush 210 and the second roller brush 220, but also enables the tangent direction of the first roller brush 210 and the tangent direction of the second roller brush 220 to be roughly consistent on the side where the first roller brush 210 and the second roller brush 220 are close to each other, so that the dirt on the first roller brush 210 and the dirt on the second roller brush 220 can be thrown out in the same direction (that is, the location of a sewage suction port 130), which is convenient for the sewage collecting channel 120 to suck sewage through the sewage suction port 130.

[0079] Specifically, in one embodiment, defined on the side where the first roller brush 210 and the second roller brush 220 are close to each other, the rolling surface of the first roller brush 210 has a first tangent direction, and the rolling surface of the second roller brush 220 has a second tangent direction. The first tangent direction refers to the extension direction of the first tangent of the rolling surface at the minimum radius of the first roller brush 210, and the second tangent direction refers to the extension direction of the second tangent of the rolling surface at the minimum radius of the second roller brush 220. The tangent of the rolling surface at any position on the second roller brush 220, the tangent at the longest free end of the second rib 222, the tangent at the longest free end of the first rib 221, and the tangent of the rolling surface at any position on the first roller brush 210 are all located between the first tangent and the second tangent. Therefore, the area between the first tangent and the second tangent defines the maximum sewage discharge area of ​​the first roller brush 210 and the second roller brush 220.

[0080] Based on the above, when the installation cavity 110 and the sewage collecting channel 120 are connected through the sewage suction port 130, the sewage suction port 130 is located in the first tangential direction and the second tangential direction. In this way, the opening range of the sewage suction port 130 can be sufficient to cover the maximum sewage discharge area mentioned above, so that the dirt of the first roller brush 210 and the second roller brush 220 is driven by rotation to enter the sewage collecting channel 120 through the sewage suction port 130.

[0081] Based on any of the above embodiments, the driving mechanism 230 provides driving force for the rotation of the first roller brush 210 and the second roller brush 220:

[0082] In one embodiment, the rotational drive obtained by the first roller brush 210 and the rotational drive obtained by the second roller brush 220 can remain independent of each other, that is, the driving mechanism 230 directly provides rotational driving force to the first roller brush 210 and the second roller brush 220 respectively. Specifically, the driving mechanism 230 includes a first driving component and a second driving component, wherein the first driving component is drivingly connected to the first rolling brush 210 to drive the first rolling brush 210 to rotate at a first speed; the second driving component is drivingly connected to the second rolling brush 220 to drive the second rolling brush 220 to rotate at a second speed; wherein, under the driving of the first driving component and the second driving component, the first rolling brush 210 and the second rolling brush 220 rotate at a differential speed, that is, the first speed and the second speed are not equal, so that a relative rotation stroke can be formed between the first rolling brush 210 and the second rolling brush 220, and in the relative rotation stroke, the abutment of the first rolling brush 210 and the second rolling brush 220 generates relative movement (for example, between the first rib 221 and the rolling surface of the first rolling brush 210), which helps, for example, the relative movement to achieve mutual cleaning between the first rolling brush 210 and the second rolling brush 220. wherein, the first speed is generally set to be no greater than the second speed, which helps to optimize the cleaning effect of the surface to be cleaned, the first rolling brush 210 and the second rolling brush 220.

[0083] The scheme of the first drive assembly and the second drive assembly is not limited, and can be directly composed of a driver, such as a motor or a rotary cylinder; or can be composed of a combination of a driver and a transmission assembly, wherein, when the driver provides a rotational output, the transmission assembly can be, for example, a gear set, a pulley assembly, etc.; when the driver provides a linear output, the transmission agency case number is:

[0084] The moving assembly may be, for example, a screw-nut assembly, a gear rack assembly, or the like.

[0085] Of course, in another embodiment, on the side where the first roller brush 210 and the second roller brush 220 are close to each other, the first roller brush 210 and the second roller brush 220 are at least partially connected by interference, and the driving mechanism 230 is drivingly connected to the first roller brush 210 or the second roller brush 220. That is, the driving mechanism 230 only provides direct rotational driving force to the first roller brush 210 or the second roller brush 220, and the remaining roller brush indirectly receives the rotational driving force of the driving mechanism 230 through the interference connection between the first roller brush 210 and the second roller brush 220. In this way, there is no need to arrange two sets of rotation mechanisms, and there is no need to provide a linkage structure for the transmission connection between the first roller brush 210 and the second roller brush 220.

[0086] Further, in one embodiment, on the side where the first roller brush 210 and the second roller brush 220 are close to each other, the second rib 222 extends toward the first roller brush 210 to movably abut against the rolling surface of the first roller brush 210, so as to achieve interference connection between the first roller brush 210 and the second roller brush 220. In view of the above, the second rib 222 has sufficient structural strength, and when movably abutting against the rolling surface of the first roller brush 210, it is equivalent to linking the first roller brush 210 and the second roller brush 220, so as to achieve the purpose of transmitting the rotational driving force of the first roller brush 210 to the second roller brush 220. And because the protruding length of the first rib 221 is longer than the protruding length of the second rib 222, it can be ensured that between the first roller brush 210 and the second roller brush 220, at least the first rib 221 movably abuts against the rolling surface of the first roller brush 210, which is conducive to power transmission and mutual cleaning of the first roller brush 210 and the second roller brush 220.

[0087] In addition, please combine Figure 2 , Figure 4 , Figure 6 and Figure 7 :

[0088] In one embodiment, the machine body 100 may further be provided with a rear baffle 170 protruding outwardly at the rear side of the second opening 112 of the installation cavity 110 . The arrangement of the rear baffle 170 may refer to the front baffle 160 , and will not be described in detail.

[0089] In one embodiment, the body 100 may further protrude another stop structure 180 on the other side of the dirt suction port 130 opposite to the stop member 150, which can be movably abutted against the rolling surface of the first roller brush 210, and also helps to further scrape out the dirt on the first roller brush 210.

[0090] In one embodiment, the body 100 may be provided with a water divider 300 on the base, and the water inlet of the water divider 300 is connected to the above-mentioned clean water tank, cleaning liquid tank and / or external water source, and the water divider 300 has one or more water outlets arranged along the axial extension of the first roller brush 210 and the second roller brush 220, and each water outlet is at least facing the first roller brush 210, and can provide clean water and / or cleaning liquid to the first roller brush 210.
