[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] See also Figure 1-2FIG. 1 shows a roller assembly 1 according to a first embodiment of the present invention. The roller assembly 1 comprises a roller 11, an elastic support member 12 wrapped around the outside of the roller 11, and a wiper 13 sleeved on the outside of the elastic support member 12. The elastic support member 12 is closely matched with the roller 11 and the wiper 13, respectively, so that the elastic support member 12 can rotate synchronously with the roller 11 and the wiper 13. In other words, there is no relative rotation or slippage between the roller 11 and the elastic support member 12, and between the elastic support member 12 and the wiper 13. When the drive assembly 3 (see FIG. 11 ) is driven, the roller 11 and the elastic support member 12 are driven by the drive assembly 3. Figure 5 ) When the driving roller 11 rotates, the roller 11 drives the elastic support member 12 to rotate circumferentially, and then drives the wiping member 13 to rotate circumferentially to perform cleaning operations.

[0031] Furthermore, the roller 11 is a rigid material that does not absorb water and is not easily deformed, so that the drum assembly 1 has a certain rigidity, and the inside of the drum assembly 1 is not easy to hide water, which is convenient for cleaning the drum assembly 1. The elastic support member 12 is a discontinuous structure and is an elastic non-absorbent material, which can save materials and reduce the cost of the drum assembly 1. At the same time, it prevents the problem of the drum assembly 1 being easy to hide dirt and grime due to the elastic support member 12 absorbing water. The elastic discontinuous structure also enables the drum assembly 1 to have a large garbage passing capacity, so that the drum assembly 1 can simultaneously meet the requirements of strong cleaning power and easy to wipe clean. In addition, the roller 11 and the elastic support member 12 are both non-absorbent materials, which can prevent the drum assembly 1 from absorbing water and becoming heavy, making it easy to move and improving the user experience. The wiper 13 is an elastic absorbent material, for example, it can be a water-absorbent cloth fiber or sponge material or a disposable wiper 13, etc., so that the wiper 13 can carry moisture and bind impurities, thereby improving the cleaning ability.

[0032] It should be noted that the discontinuous structure referred to in this application is relative to the continuous structure. The continuous structure means that the interior of the elastic support member 12 is solid and has a complete outer surface. The discontinuous structure means that the interior of the elastic support member 12 is discontinuous, and there is a partial hollow structure inside, or the outer surface of the elastic support member 12 is discontinuous, and there is at least a partial depression in the outer surface.

[0033] Furthermore, the material rigidity of the elastic support member 12 is less than that of the wiping member 13, and the radial thickness of the elastic support member 12 is greater than that of the wiping member 13. In one embodiment, the radial thickness of the elastic support member 12 is 6-10 mm, and the radial thickness of the wiping member 13 is 5-7 mm. With such a configuration, the thickness of the water-absorbent wiping member 13 in the drum assembly 1 is small, the water consumption during cleaning is small, and the surface to be cleaned, such as the ground, is not easy to leave water marks. Moreover, since the thickness and elasticity of the elastic support member 12 are large, the drum assembly 1 can have better garbage passing capacity and deformation recovery capacity when encountering large-sized garbage. The size and weight of the drum assembly 1 before and after use do not change much, which improves the precision of the coordination between the structures and the user experience. Moreover, after the work is completed, the water retained in the drum assembly 1 is small, and it can quickly become dry under the action of evaporation, so the drum assembly 1 will not mold or smell. Moreover, when it is used again after being placed for a period of time, it does not need to go through a long water absorption process, which is convenient to use. In addition, by setting the radial thickness of the elastic support member 12 to be larger, it is convenient to set structural supports such as elastic ribs 123 between the inner wall 121 and the outer wall 122 of the elastic support member 12, so that it has a large deformation amount when squeezing large garbage, thereby obtaining a greater garbage passing capacity.

[0034] Furthermore, the inner wall 121 of the elastic support member 12 is tightly matched with the outer side of the roller 11. A first clamping portion 111 is provided on the outer circumference of the roller 11, and a second clamping portion 1211 is correspondingly provided on the inner wall 121 of the elastic support member 12. The roller 11 and the elastic support member 12 are tightly connected through the first clamping portion 111 and the second clamping portion 1211.

[0035] In this embodiment, the first clamping portion 111 is a slot, and the second clamping portion 1211 is a protrusion. A plurality of slots extending along the axial direction of the roller 11 are provided on the side of the roller 11 facing the elastic support member 12, and a plurality of protrusions are correspondingly provided on the inner wall 121 of the elastic support member 12, and the protrusions are correspondingly connected with the slots, so that the roller 11 and the elastic support member 12 are tightly connected and synchronously rotated. In other embodiments, the first clamping portion 111 can also be a slot, and the second clamping portion 1211 is a protrusion, that is, a plurality of protrusions extending along the axial direction of the roller 11 are provided on the side of the roller 11 facing the elastic support member 12, and a plurality of slots are correspondingly provided on the inner wall 121 of the elastic support member 12, and the protrusions are correspondingly connected with the slots. Alternatively, the first clamping portion 111 and the second clamping portion 1211 are other fixedly connected structures, and the present invention is not limited to this, as long as the roller 11 and the elastic support member 12 can be tightly connected and synchronously rotated. By providing the first clamping portion 111 and the second clamping portion 1211, the elastic support member 12 can roll and fit closely with the shaft without the assistance of other positioning structures, which is conducive to reducing production costs. In addition, the roller 11 and the elastic support member 12 can be detachably connected, and when replacement is needed, they can be removed and replaced separately.

[0036] Furthermore, the outer wall 122 of the elastic support member 12 is tightly fitted and connected to the inner wall of the wiping member 13. The tightly fitted connection method includes but is not limited to the elastic support member 12 and the wiping member 13 being bonded and connected, for example, by Velcro or by brushing glue on the outer wall 122 of the elastic support member 12 or by adhesive tape. Alternatively, the elastic support member 12 and the wiping member 13 are snap-fitted and connected, for example, by setting a protrusion and a groove to achieve a snap-fit ​​connection. Alternatively, the hair is directly implanted on the outer wall 122 of the supporting elastic member. Alternatively, the wiping member 13 is elastically contracted on the outer wall 122 of the elastic support member 12. In this way, the elastic support member 12 and the wiping member 13 are kept tightly fitted, and the elastic support member 12 and the wiping member 13 will not be separated from each other due to being squeezed, thereby affecting the life of the roller assembly 1.

[0037] In this embodiment, the elastic support member 12 is a discontinuous structure to reduce production costs and improve the elastic deformation ability of the elastic support member 12, thereby improving the garbage passing ability. The elastic support member 12 includes an inner wall 121 facing the roller 11 and an outer wall 122 facing the wiper 13. A plurality of elastic ribs 123 are provided between the inner wall 121 and the outer wall 122, and the plurality of elastic ribs 123 are spaced between the inner wall 121 and the outer wall 122. By providing the elastic ribs 123, the elastic support member 12 has a certain rigid skeleton, which plays a role in supporting the wiper 13, and has a certain elastic force, which can undergo a certain deformation, thereby having a greater garbage passing ability. In other embodiments, the elastic support member 12 may also be a continuous structure.

[0038] In this embodiment, the elastic ribs 123 are plate-shaped and extend along the length direction of the elastic support member 12. A plurality of plate-shaped elastic ribs 123 are arranged at equal angles between the inner wall 121 and the outer wall 122 with the axis of the elastic support member 12 as the center, and the width of the plate-shaped elastic member is equal to the radial thickness of the elastic support member 12, and the length is equal to the length of the elastic support member 12. Specifically, each elastic rib 123 includes a first end 1231 connected to the inner wall 121 and a second end 1232 connected to the outer wall 122. The number of the first ends 1231 on the inner wall 121 is the same as the number of the second ends 1232 on the outer wall 122, and each first end 1231 is connected to each second end 1232 in a one-to-one correspondence. In other words, any two adjacent elastic ribs 123 do not intersect, that is, the elastic ribs 123 are trapezoidal in the radial cross section of the elastic support member 12. In this way, the elastic rib 123, in other embodiments, the length of the elastic rib 123 can also be less than the length of the elastic support member 12, two or more elastic ribs 123 are arranged in the length direction of the elastic support member 12, and the elastic ribs 123 are arranged at intervals to save materials and reduce costs. The present invention is not limited to this.

[0039] Furthermore, the roller assembly 1 is a structure with blocked ends, and the driving assembly 3 ( Figure 5 ) is connected to the roller 11 in the drum assembly 1 through the connecting member 14, thereby driving the drum assembly 1 to rotate. In this way, the thrust of the user on the cleaning tool can be reduced, and the user experience can be improved.

[0040] Further, the roller assembly 1 also includes a connecting member 14 that is transmission-connected to the driving assembly 3. The connecting member 14 is connected to the side of the roller 11 away from the elastic support member 12 and is configured to drive the roller 11 to rotate in the circumferential direction. In this embodiment, the inner side surface of the roller 11 is provided with a first matching portion 112, and the outer peripheral wall of the connecting member 14 is provided with a second matching portion 141 that is tightly matched with the first matching portion 112. The transmission connection between the connecting member 14 and the roller 11 is achieved through the tight match between the first matching portion 112 and the second matching portion 141. Optionally, the first matching portion 112 is a connecting groove, and the second matching portion 141 is a connecting tooth. The connecting tooth is meshed and connected in the connecting groove to achieve the transmission connection between the roller 11 and the connecting member 14. When the first matching portion 112 is a connecting groove and the first clamping portion 111 is a protrusion, the connecting groove and the protrusion are respectively arranged on opposite sides of the roller 11, and correspond to each other one by one, and are formed and arranged in one step through a stamping process to simplify the manufacturing process of the roller 11 and reduce the process cost. It should be noted that, in other embodiments, the first matching portion 112 and the second matching portion 141 may also be other structures, or the connecting member 14 and the roller 11 may be integrally formed, and the present invention is not limited to this.

[0041] The roller 11 is provided with a roller support 15 at one end away from the connecting member 14, and the roller support 15 is configured to support the roller assembly 1. The roller support 15 includes a roller end face connecting member 151 and a roller end face shaft pin 152. The roller end face connecting member 151 includes an end cover portion and a columnar portion extending from the end cover portion toward the roller 11, and a protrusion is provided on the outer surface of the columnar portion, and the protrusion is engaged with the inner surface of the roller 11. The roller end face connecting member 151 is also provided with an inner hole that penetrates the roller end face connecting member 151 along the length direction, and one end of the roller end face shaft pin 152 is inserted into the inner hole to support the other end of the roller 11.

[0042] See also Figure 3 As shown, it is a roller assembly 1 of the second embodiment of the present invention. The roller assembly 1 of this embodiment includes a roller 11, an elastic support member 12 and a wiping member 13 which are sequentially sleeved and connected from the inside to the outside. The elastic support member 12 is tightly matched with the roller 11 and the wiping member 13 respectively, and keeps synchronous rotation with the roller 11 and the wiping member 13. The elastic support member 12 includes an inner wall 121 facing the roller 11 and an outer wall 122 facing the wiping member 13. A plurality of elastic ribs 123 are provided between the inner wall 121 and the outer wall 122 to make the inner wall 121 and the outer wall 122 discontinuous so as to increase the deformation of the roller assembly 1, thereby making the roller have a larger garbage passing capacity, and at the same time to prevent the problem that the roller assembly 1 absorbs too much water and is difficult to clean, and is easy to hide dirt, so that the roller assembly 1 can simultaneously meet the requirements of strong cleaning power and easy to wipe water clean, thereby improving user usage needs. That is, the structure and material of the roller assembly 1 in the second embodiment are substantially the same as those of the roller assembly 1 in the first embodiment, except that the elastic ribs 123 are arranged differently, so the following content only describes the differences, and the similarities are not repeated.

[0043] In the present embodiment, the elastic ribs 123 are plate-shaped, and two adjacent elastic ribs 123 intersect. That is, the elastic ribs 123 are triangular in the radial cross section of the elastic support member 12. Specifically, each elastic rib 123 includes a first end 1231 connected to the inner wall 121 and a second end 1232 connected to the outer wall 122, and the number of the first ends 1231 on the inner wall 121 is the same as the number of the second ends 1232 on the outer wall 122. Along the radial direction of the elastic support member 12, the projections of several first ends 1231 on the inner wall 121 of the elastic support member 12 and the projections of several second ends 1232 on the inner wall 121 of the elastic support member 12 do not overlap, that is, they are staggered, and each first end 1231 and each second end 1232 are connected to two elastic ribs 123. In this way, the rigidity of the elastic support member 12 can be effectively improved to prevent the elastic support member 12 from being damaged during cleaning.

[0044] See also Figure 4The figure shows a roller assembly 1 according to a third embodiment of the present invention. The structure and material of the roller assembly 1 according to the third embodiment are substantially the same as those of the roller assembly 1 according to the first embodiment, except that the elastic ribs 123 are arranged in a different manner, so the following content only describes the differences, and the similarities are not repeated.

[0045] In the present embodiment, the elastic rib 123 is arc-shaped, and two arc-shaped elastic ribs 123 are symmetrically arranged. Each elastic rib 123 includes a first end 1231 connected to the inner wall 121 and a second end 1232 connected to the outer wall 122, and the number of the first ends 1231 on the inner wall 121 is different from the number of the second ends 1232 on the outer wall 122. Preferably, the number of the second ends 1232 is less than the number of the first ends 1231, and the second ends 1232 are connected to the two first ends 1231 spaced apart. That is, the elastic rib 123 is an arc-shaped triangle that crosses in pairs in the radial cross section of the elastic support member 12. The two arc-shaped sides connected to the vertex of each arc-shaped triangle and the second end 1232 are symmetrically arranged about the vertex of the second end 1232, and the two arc-shaped triangles are symmetrically arranged about their intersection. In this way, the rigidity of the elastic support member 12 can be effectively improved to prevent the elastic support member 12 from being damaged during cleaning.

[0046] It should be noted that, in other embodiments, the elastic rib 123 may also be block-shaped, such as a block-shaped with a square cross section. Alternatively, the elastic rib 123 may also have a variety of cross-sectional shapes, such as a triangular or trapezoidal sawtooth shape.

[0047] The present invention provides a cleaning head 100, which includes at least one roller assembly 1, a roller brush cover 2 covering the roller assembly 1, and a driving assembly 3 connected to the roller assembly 1. Each roller assembly 1 includes a roller 11, an elastic support member 12, and a wiping member 13, which are sequentially sleeved and connected from the inside to the outside. The elastic support member 12 is closely matched with the roller 11 and the wiping member 13, and keeps synchronous rotation with the roller 11 and the wiping member 13. The elastic support member 12 includes an inner wall 121 facing the roller 11 and an outer wall 122 facing the wiping member 13, and a plurality of elastic ribs 123 arranged non-parallel are arranged between the inner wall 121 and the outer wall 122. In this way, the inner wall 121 and the outer wall 122 of the elastic support member 12 are discontinuous, so that the deformation amount of the roller assembly 1 can be increased, so that the roller has a larger garbage passing capacity, and at the same time, the roller assembly 1 is prevented from absorbing too much water and being difficult to clean, and easily hiding dirt, so that the roller brush assembly can simultaneously meet the requirements of strong cleaning power and easy to wipe clean, thereby improving the user experience.

[0048] In order to clearly illustrate the structure of the cleaning head 100 , the following description will be given by taking the cleaning head 100 including two roller assemblies 1 as an example, but the description should not be limited thereto.

[0049] See also Figure 5-7 Combined with Figure 1-4 As shown, the cleaning head 100 includes two roller assemblies 1, which are arranged in parallel along the front-to-back direction of the cleaning head 100, and the two roller assemblies 1 rotate in opposite directions. The roller assembly 1 near the front of the cleaning head 100 rotates counterclockwise, and the other roller assembly 1 rotates clockwise, so that a suction port 4 is formed between the two roller assemblies 1, and a suction channel 5 is provided on the roller brush cover 2. The suction port 4 is located below the suction channel 5 and is connected to the suction channel 5.

[0050] Two scraping strips 21 are provided on the side of the roller brush cover 2 facing the roller assembly 1. The two scraping strips 21 are respectively arranged on both sides of the suction channel 5 along the front-to-back direction and are located above the two roller assemblies 1. They are interference-connected with the roller assemblies 1 and are configured to squeeze and scrape off the dirt on the roller assembly 1. The outer diameter of the roller assembly 1 after the roller assembly 1 is wiped by the scraping strips 21 is defined as the outer diameter of the wiper roller brush. The closed space 6 is formed between the outer diameter of the front wiper roller brush + the outer diameter of the rear wiper roller brush + the front scraping strip 21 + the rear scraping strip 21. Since the suction channel 5 is under negative pressure, the closed space 6 is also a negative pressure cavity. The dirt squeezed and scraped by the scraping strips 21 is sucked by the suction channel 5 in the closed space 6 and then sent to the trash can of the cleaning device (not shown).

[0051] When cleaning small garbage, the small garbage mainly enters the closed space 6 through the deformation A of the wiping members 13 in the two roller assemblies 1, and at this time, the elastic supporting members 12 in the two roller assemblies 1 are basically not deformed or only slightly deformed. When cleaning large garbage, the large garbage enters the closed space 6 through the deformation A of the wiping members 13 in the two roller assemblies 1 + the deformation B of the elastic supporting member 12 in the front roller assembly 1 + the deformation C of the elastic supporting member 12 in the rear roller assembly 1, so that the cleaning head 100 has a greater garbage passing capacity, improving the cleaning effect and cleaning efficiency.

[0052] Furthermore, the two roller assemblies 1 are driven simultaneously by a driving assembly 3. In this embodiment, the driving assembly 3 is a gear transmission device, including a driving motor 31 and a gear set 32. The driving motor 31 is arranged above the roller assembly 1, and the gear set 32 ​​is arranged between the front gear cover and the rear gear cover and is located on the side of the roller assembly 1. A sun gear is sleeved on the motor shaft of the driving motor 31, and the sun gear is meshed with the gear set 32. The gear set 32 ​​is respectively connected to the roller shafts 11 of the two roller assemblies 1 through two connecting members 14. The driving motor 31 drives the two roller assemblies 1 to rotate circumferentially in opposite directions through the gear set 32.

[0053] The end of the cleaning head 100 away from the connecting member 14 is provided with a roller connecting member 7, and the roller connecting member 7 is configured to fix the roller assembly 1 to the cleaning head 100. Specifically, the roller connecting member 7 is fixed to the cleaning head 100, and the roller end face shaft pin 152 in the roller support member 15 is rotatably connected to the roller connecting member 7.

[0054] Furthermore, two fluid distribution devices 8 are provided on the side of the roller brush cover 2 facing away from the roller assembly 1. The two fluid distribution devices 8 are respectively arranged above the two roller assemblies 1 to automatically clean the two roller assemblies 1 respectively, thereby increasing the service life of the roller assembly 1, improving the cleaning efficiency and cleaning effect, and thus improving the user experience. The roller brush cover 2 is provided with a plurality of through holes 22 at the position corresponding to the fluid distribution device 8, and the fluid distribution device 8 provides the cleaning fluid to the roller assembly 1 through the through holes 22. The cleaning liquid is provided to the surface to be cleaned through the movement of the roller assembly 1, so that the roller assembly 1 performs wet cleaning on the surface to be cleaned. Of course, when the fluid distribution module does not provide cleaning liquid to the roller assembly 1, the roller assembly 1 can also perform dry cleaning on the surface to be cleaned. It should be noted that the cleaning liquid can be water or a mixture of water and cleaning liquid.

[0055] Two wipers 23 are also provided on the side of the roller brush cover 2 facing the roller assembly 1. The two wipers 23 are arranged outwardly relative to the two fluid distribution devices 8 and are respectively interference fit with the two roller assemblies 1. After the fluid distribution device 8 provides cleaning liquid to the roller assembly 1, the fluid on the roller assembly 1 can be evenly spread through the two wipers 23 to avoid uneven fluid on the roller assembly and affect the cleaning effect.

[0056] The cleaning head 100 also includes a scraper 9 arranged behind the roller brush assembly. The scraper 9 contacts the surface to be cleaned and is used to scrape off residual dirty liquid and stubborn garbage on the surface to be cleaned, so as to perform secondary cleaning on the surface to be cleaned, improve the cleaning effect, and help keep the surface dry, avoiding the risk of slipping due to water on the surface after cleaning, and causing secondary pollution.

[0057] The present invention provides a cleaning device (not shown), which is used to clean a surface to be cleaned, and includes the above-mentioned cleaning head 100 and roller assembly 1. The surface to be cleaned can be a floor, a wall or a dirty surface of other objects. The present application does not specifically limit the application target or application scenario of the cleaning device. In the present embodiment, the cleaning device is a floor scrubber, which is used to wet clean the surface to be cleaned. The floor scrubber has both a suction function and a mopping function.
