Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310475457.7, entitled "A Cover Assembly, a Cleaning Head Assembly and a Scrubber" the content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning equipment, in particular to a cover assembly, a cleaning head assembly and a scrubber. BACKGROUND

[0003] With the gradual improvement of living standards, people's requirements for the quality of life are also getting higher and higher, and more and more people lay exquisite floor or tiles on the ground of the house. When the floor or tiles are dirty and need to be cleaned, the traditional method is to use a broom, mop or mop to clean. This method is time-consuming and laborious, and cannot improve people's interest in cleaning work, which is not conducive to maintaining a clean indoor environment. Therefore, there is a scrubber. The scrubber is a cleaning machine suitable for hard floor cleaning, simultaneous sewage absorption, and sewage removal from the scene.

[0004] At present, the sewage generated by the scrubber when cleaning the ground usually flows into the sewage tank through a water tank in the scrubber.

[0071] The scheme of the present application will be described in detail below in conjunction with the accompanying drawings.

[0072] As analyzed in the background art of the present application, the existing sewage tank of the scrubber is prone to blockage, in order to solve the above technical problems, for this purpose, as Figures 1 to 7As shown in the first aspect, the embodiment of the present application provides a cover assembly 2 for covering a cleaning roller 4 of a scrubber, which comprises a cover body 20, a pressing rib 21, a guide strip 22 and a locking mechanism (not shown in the figure), the cover body 20 is arranged on a cleaning head housing 1; the pressing rib 21 is arranged on the cover body 20 and protrudes towards the cleaning roller and abuts against the cleaning roller; the guide strip 22 is arranged on the cover body 20 and protrudes towards the cleaning roller and abuts against the cleaning roller; the locking mechanism is arranged on the cover body 20 and is used to lock / unlock the cover body 20 on the cleaning head housing; wherein the pressing rib 21 and the guide strip 22 form a water groove (not shown in the figure) on the cover body 20, a filter 23 is arranged in the water groove, one end of the water groove is connected to a clean water tank 51 of the scrubber, and the other end of the water groove is connected to a sewage tank 52 of the scrubber.

[0073] The cover assembly 2 provided by the embodiment is arranged on the cleaning head housing 1 of the scrubber and is used to cover the cleaning roller 4 of the scrubber, which comprises the cover body 20, the pressing rib 21 and the guide strip 22, the pressing rib 21 and the guide strip 22 are arranged on the cover body 20 to form a water groove, the guide strip 22 is used to block the sewage squeezed out of the cleaning roller 4 from flowing into the garbage collection assembly 7, after the cover assembly 2 is arranged on the cleaning head housing 1 of the scrubber, the pressing rib 21 and the guide strip 22 abut against the cleaning roller 4 installed in the cleaning head housing 1, the pressing rib 21 is used to squeeze out the excess water on the cleaning roller 4, and the guide strip 22 is used to block the sewage squeezed out of the cleaning roller 4 from flowing into the garbage collection assembly 7, when the cleaning roller 4 cleans the ground, the pressing rib 21 contacts and squeezes the cleaning roller 4, and at the same time, the filter 23 arranged between the pressing rib 21 and the guide strip 22 can filter the particles in the sewage to prevent the sewage from entering the sewage tank, thereby avoiding the blockage of the sewage tank. The cover assembly 2 further comprises a locking mechanism arranged on the cover body 20, when a user needs to remove the entire cover assembly 2 for maintenance and cleaning, the user can easily remove the cover assembly 2 from the cleaning head housing 1 by unlocking, and when the user needs to install the cover assembly 2 on the cleaning head housing 1, the user can stably cover the cleaning head housing 1 by multiple locking points, and even if the pressing rib 21 and the guide strip 22 simultaneously squeeze the cleaning roller 4, it will not affect the stability of the cover assembly 2 and the cleaning head housing 1.

[0074] In the embodiment, the filter 23 arranged between the pressing rib 21 and the guide strip 22 is mainly used for filtering sewage to prevent particles in the sewage from flowing into the sewage tank of the scrubber, that is, the filter 23 can be arranged between the pressing rib 21 and the guide strip 22 and before the inlet of the sewage tank, and the specific actual position can be selected according to actual application, which is not limited in the embodiment.

[0075] In some embodiments, the locking mechanism includes a pair of elastic locking pieces 24 arranged on both sides of the grommet body 20, and a first clamping locking tongue (not shown in the figure) is arranged on the elastic locking piece 24. A pair of first clamping holes 114 corresponding to the elastic locking piece 24 are arranged on the two end walls (the first end wall 11 and the second end wall 12) of the cleaning head shell 1.

[0076] In the present embodiment, a pair of elastic locking pieces 24 are arranged on both sides of the grommet body 20 at the elastic abutting positions of the two end walls (the first end wall 11 and the second end wall 12). The elastic locking piece 24 can be a clamping piece made of other materials as generally understood by those skilled in the art, or it can be a clamping hook that can be elastically deformed and formed together with the grommet body 20. The elastic locking piece 24 is provided with a first clamping locking tongue, and a pair of first clamping holes 114 corresponding to the elastic locking piece 24 are arranged on the two end walls of the cleaning head shell 1. The specific form of the first clamping locking tongue and the first clamping hole 114 is not limited in the present application, as long as the two can be smoothly and stably clamped. The design of the elastic locking piece 24 on both sides of the grommet body 20 can facilitate the user to easily align the grommet assembly 2 to the closing position of the cleaning head shell 1, and after closing in place, the user can hear a crisp clamping sound or feel a slight clamping vibration, which can remind the user that the closing action of the grommet assembly 2 has been completed.

[0077] In some embodiments, the locking mechanism further includes an elastic locking rod assembly (not shown in the figure) arranged inside the top wall of the grommet body 20 and capable of simultaneously extending and retracting on both sides of the grommet body. Each end of the elastic locking rod assembly is provided with a locking tongue (second clamping locking tongue 25), and a pair of second clamping holes 115 corresponding to the locking tongue are arranged on the two end walls (the first end wall 11 and the second end wall 12) of the cleaning head shell.

[0078] In the present embodiment, an elastic locking rod assembly (not shown in the figure) capable of simultaneously extending and retracting on both sides of the grommet body 20 is arranged inside the top wall of the grommet body 20. Each end of the elastic locking rod assembly is provided with a locking tongue (second clamping locking tongue 25). The extension or retraction of the two locking tongues can be controlled by two elastic buttons arranged in the concave part at the top of the grommet body 20. A pair of second clamping holes 115 corresponding to the locking tongue are arranged on the two end walls of the cleaning head shell 1. When the user needs to close the grommet assembly 2 to the cleaning head shell 1, in addition to the automatic locking of the aforementioned elastic locking piece 24, another step requires the user to continue to press the grommet assembly 2 downward until the two locking tongues of the elastic locking rod assembly are automatically ejected and locked into the second clamping holes 115 of the two end walls under the elastic action, which is considered to reliably complete the closing action of the grommet assembly 2. As Figure 2As shown, the two locking tongues of the elastic locking rod assembly are wider than the first clamping locking tongue in the width direction and higher than the first clamping locking tongue in the height direction. In other words, the second clamping locking tongue 25 can bear impact force in various directions after clamping in place, which is much greater than the first clamping locking tongue. The reliable and stable clamping force for covering the lid assembly 2 to the cleaning head shell 1 mainly comes from the second clamping locking tongue 25 of the elastic locking rod assembly. When the user needs to remove the lid assembly 2, the user first needs to press the two elastic buttons at the top of the lid body 20 to control the contraction of the two locking tongues, and then simply lift the entire lid assembly 2 upward.

[0079] In some embodiments, the pressing ribs 21 are integrally formed with the lid body 20 or detachably connected to the lid body 20.

[0080] In this embodiment, as shown in Figures 2 to 7 、 Figure 10 During the manufacturing process of the lid body 20, a mold can be used to form a plurality of protrusions on the surface of the lid body 20, which can directly serve as the pressing ribs 21 for pressing the cleaning roller 4. The end of the pressing rib 21 that elastically abuts against the cleaning roller 4 matches the structure of the cleaning roller 4, that is, the end of the pressing rib 21 that abuts against the cleaning roller 4 can be an arc-shaped end. Of course, the end of the pressing rib 21 that abuts against the cleaning roller 4 can be a non-arc-shaped end, such as a sawtooth-shaped end, a polygonal end, etc., which is not limited in the present embodiment. Preferably, the pressing rib 21 is a straight line with a single cross-sectional shape and is parallel to the axis of the cleaning roller 4. Further, the pressing rib 21 can be tightened towards the inside of the water tank near the two end walls (not shown in the figure), so as to prevent the entire cleaning head assembly from leaking due to excessive water pressure at the elastic abutting position of the water tank and the end wall when the entire cleaning head assembly is inclined towards the axis of the cleaning roller 4. This "tightening" has two meanings. The first meaning is that the pressing rib 21 is tightened towards the direction of reducing the width of the water tank in the width direction of the water tank. The second meaning is that the pressing rib 21 extends towards the axis of the cleaning roller 4 to increase the interference fit amount of the elastic abutment. The double meanings of "tightening towards the inside of the water tank" can further improve the water leakage prevention capability of the entire water tank under any angle of use.

[0081] In the present embodiment, the cover body 20 can be formed by a mold in the manufacturing process to reserve an interface for mounting the ribs 21 on its surface, and the ribs 21 can be detachably connected to the cover body 20 by cooperating with relevant fasteners through the mounting interface if necessary. The structure of the end of the ribs 21 that elastically abuts against the cleaning roller 4 matches the cleaning roller 4, that is, the end of the ribs 21 that abuts against the cleaning roller 4 can be an arc-shaped end or a non-arc-shaped end. After being used for a period of time, the ribs 21 and the wiping layer 41 of the cleaning roller 4 will be worn to a certain extent because the ribs 21 elastically abut against the wiping layer 41 during the working process, and the wear will seriously affect the cleaning efficiency of the entire scrubber. The cleaning roller 4 itself is positioned as a consumable material, and it should be replaced after being used for a period of time. However, the wear degree of the ribs 21 is usually small because the hardness of the ribs 21 is much higher than that of the wiping layer 41, and a small amount of wear will accumulate over time. When the wear reaches a certain degree, the cleaning efficiency of the scrubber cannot be restored even if the cleaning roller 4 is replaced, and the ribs 21 should be replaced at this time. Of course, the material for manufacturing the ribs 21 is not limited to non-metallic materials such as hard plastic, and hard metal materials with moderate cost, such as aluminum alloy, magnesium alloy, magnesium-aluminum alloy, zinc alloy, and stainless steel, can also be used to manufacture the ribs 21. As for the interface form used when the ribs 21 are mounted to the cover body 20, those skilled in the art can use common interface structures such as a flat stepped structure, a recessed or protruding interface structure, and the like, and the present embodiment is not limited in this regard.

[0082] In some embodiments, the guide bars 22 are integrally formed with the cover body 20 or are detachably connected to the cover body 20.

[0083] In the present embodiment, the grommet body 20 can be formed by a mold during manufacture to form a plurality of protrusions on its surface, which can also directly serve as the guide strip 22 for blocking the flow of the squeezed dirty water on the wiping layer 41 of the cleaning roller 4 into the garbage collection assembly 70. The structure of the end of the guide strip 22 that elastically abuts against the cleaning roller 4 can also be matched with the cleaning roller 4, that is, the end of the guide strip 22 that abuts against the cleaning roller 4 can be an arc-shaped end. Preferably, in order to increase the ability of the guide strip 22 to suppress the cleaning roller 4 from flinging out liquid outwardly during high-speed rotation, the end of the guide strip 22 that elastically abuts against the wiping layer 41 can be provided in a crescent-shaped end portion (not shown in the drawing) that has two pointed portions that elastically abut against the wiping layer 41 and a middle portion that arches outwardly away from the wiping layer 41. Of course, in order to further reduce the resistance of the cleaning roller 4 during high-speed rotation, the crescent-shaped end portion of the guide strip 22 that elastically abuts against the wiping layer 41 can also only have the pointed portion near the end of the pressing rib 21 that elastically abuts against the wiping layer 41. The other pointed portion can facilitate the brush assembly 3 in the cleaning head assembly to direct the brushed-off solid garbage and sticky garbage to the garbage collection assembly 7 during high-speed rotation, so as to avoid the garbage being flung back onto the surface of the wiping layer 41 again by the brush assembly after one rotation. Of course, the end of the guide strip 22 that elastically abuts against the wiping layer 41 can also be designed in any shape that can achieve the above functions, such as a sickle shape or a wedge shape, and the present embodiment is not limited in this regard.

[0084] In the present embodiment, as shown in Figures 3 to 7 、 Figure 10 the grommet body 20 can be formed by a mold during manufacture to reserve an interface for mounting the guide strip 22 on its surface. The mounting interface can be used to realize the detachable connection of the guide strip 22 and the grommet body 20 by cooperating with relevant fasteners if necessary. The guide strip 22 can also directly serve as a component for blocking the flow of the squeezed dirty water on the wiping layer 41 of the cleaning roller 4 into the garbage collection assembly 7. The specific structure of the end of the guide strip 22 that elastically abuts against the cleaning roller 4 can be consistent with the description in the foregoing embodiment, and thus will not be repeated here. Figures 2 to 6 、 Figure 10As shown, the grommet body 20 is provided with a clamping groove (not shown in the drawing) for clamping the guide bar 22 on the inner side of the cleaning roller 4 between the pressing rib 21 and the brush assembly 3. The guide bar 22 is provided with a clamping end (not shown in the drawing) at the other end away from the cleaning roller 4, which is elastically clamped with the clamping groove. Preferably, the clamping end is elastically clamped with the clamping groove on both sides of the elastic barb structure (not shown in the drawing), which facilitates the user to easily clamp the clamping end into the clamping groove when replacing the guide bar 22. Preferably, the guide bar 22 is a straight line with a single cross-sectional shape and parallel to the axis of the cleaning roller 4. Further, the guide bar 22 can be tightened towards the inside of the water tank near the two end walls, so as to prevent the entire cleaning head assembly from leaking due to excessive water pressure at the elastic abutment of the water tank and the end wall when the entire cleaning head assembly is tilted towards the axial side of the cleaning roller 4. This "tightening" has two meanings, as discussed in the foregoing embodiment of the "two-end tightening" of the pressing rib 21, which will not be repeated here.

[0085] In some embodiments, one end of the filter 23 is connected to the pressing rib 21.

[0086] In the present embodiment, the filter 23 is detachably connected at the end of the pressing rib 21 abutting against the cleaning roller 4 and on the side facing the guide bar 22. The lower surface of the filter 23 extends towards the guide bar 22 along the surface of the roller assembly. The filter 23 can filter the large-particle garbage and undissolved particle garbage in the water tank brought in by the cleaning roller 4. Over time, some sticky garbage will inevitably accumulate on the upper and lower surfaces of the filter 23. The detachable filter 23 design facilitates the user to detach the filter 23 for thorough cleaning at regular intervals when the simple large-water flushing mode cannot thoroughly clean the filter 23, so as to maintain the health and hygiene of the user's home environment.

[0087] In some embodiments, as Figures 4 to 6 shown, the filter 23 extends towards the guide bar 22 from the side of the pressing rib 21 facing the guide bar 22, and the lower surface of the filter 23 leaves a gap with the surface of the cleaning roller 4. The filter 23 is detachably connected to the pressing rib 21.

[0088] In this embodiment, the filter 23 is detachably connected to the side of the pressure rib 21 which is in abutment with the cleaning roller 4 and faces the guide strip 22. A gap is left between the lower surface of the filter 23 and the upper surface of the wiping layer 41 of the cleaning roller 4, and the filter 23 extends towards the guide strip 22. A gap (not shown in the figure) is left between the lower surface of the filter 23 and the upper surface of the wiping layer 41, which allows the sewage squeezed out by the pressure rib 21 to further flush the upper surface of the wiping layer 41, and prevents fine-particle garbage from depositing on the lower surface of the filter 23. On the other hand, the gap allows air in the space to circulate, so that even when the scrubber is not in use, the garbage deposited in the space will not stink due to long-term sealing. The filter 23 has the functions described in the foregoing embodiments, which will not be described here again.

[0089] Further, in this embodiment, as shown in Figures 4 to 6 , the extended end of the filter 23 (not shown in the figure) is provided with a hook portion (not shown in the figure) extending away from the surface of the roller assembly in the normal direction, and the front end surface of the hook portion is spaced apart from the vertical surface of the guide strip 22 (not shown in the figure).

[0090] In this embodiment, the hook portion of the filter 23 extends away from the surface of the roller assembly to form a filter extension hook portion 281. When the user is sweeping a waterlogged floor with the scrubber, and the sewage flow in the sump is too large when the water sucked up by the cleaning roller 4 is squeezed out by the pressure rib 21, the filter extension hook portion 281 can prevent the sewage from overflowing the top end of the filter extension hook portion 281 extending away from the surface of the roller assembly in the normal direction, so that the squeezed-out sewage must pass through the filter 23 before being guided to the sewage outlet 112 at one end of the sump and then further conveyed to the sewage tank 52, thereby preventing the sewage channel from being blocked by the sewage bypassing the filter 23. As shown in Figures 5 to 7 、 Figure 11 , the filter extension hook portion 281 continues to extend in a direction parallel to the upper surface of the wiping layer 41 until it is connected to the guide strip 22. The portion between the filter extension hook portion 281 and the guide strip 22 is called a filter extension connecting portion 282, which reliably connects the filter extension hook portion 281 and the guide strip 22. However, not all the opposite portions of the filter extension hook portion 281 and the guide strip 22 need to be reliably connected. The filter extension connecting portion 282 can connect the opposite portions of the filter extension hook portion 281 and the guide strip 22 at intervals along the axial direction of the cleaning roller 4. The interval portion forms the sump opening area 27 of the sump. The filter extension hook portion 281 and the filter extension connecting portion 282 are collectively referred to as a filter extension portion 28. As shown in Figure 11As shown, the front end surface of the filter member extending the hook portion 281 leaves a gap with the vertical surface of the guide strip 22, and we call this vertical gap space as the large particle garbage containing area J, so that a small amount of large particle garbage brought by the cleaning roller 4 and not brushed by the brush can be hoisted into the sink. This gap space can often contain these large particle garbage to be constantly turned "stayed" here. When the gap between the lower surface of the filter member 23 and the wiping layer 41 is smaller than the diameter of the large particle garbage, the large particle garbage is turned to the sink opening area 27 with the gap space volume slowly increasing, and is freely "limited" in the space, so as not to be stuck in the narrow gap between the lower surface of the filter member 23 and the wiping layer 41 for a long time. Moreover, once the large particle garbage is stuck in the gap between the lower surface of the filter member 23 and the wiping layer 41, the large particle garbage is easy to scratch the surface of the wiping layer 41, thereby reducing the service life of the cleaning roller 4.

[0091] In some embodiments, as shown in Figures 2 to 12 As shown, the filter member 23 is integrally formed with the gland body 20.

[0092] Similarly, the protrusion formed in the manufacturing process of the gland body 20 can also be used as the filter member 23 for filtering the particle garbage in the sewage. When the cleaning roller 4 is installed in the cleaning head housing 1, the protrusion also abuts against the cleaning roller 4, and a plurality of mesh holes 231 are arranged on the protrusion. The sewage in the sink can be further filtered by the mesh holes 231, and the filtered sewage can be further transported to the sewage tank 52 through the sewage outlet 112 of the sink, thereby preventing the sewage channel from being blocked.

[0093] It should be noted that the mesh holes 231 on the filter member 23 can be formed during the molding of the gland body 20, or can be machined after the molding of the gland body 20. They can be selected according to actual application, and the present embodiment is not limited in particular.

[0094] It should be further noted that the pressing ribs 21, the guide strip 22 and the filter member 23 can be single-shot molded during the molding of the gland body 20, or can be sequentially molded by multiple-shot molding. That is, the pressing ribs 21, the guide strip 22, the filter member 23 and the gland body 20 can be integrally formed.

[0095] In some embodiments, one end of the filter member 23 is arranged on the gland body 20, and the other end abuts against the cleaning roller 4.

[0096] In the embodiment, the free end of the filter piece 23 elastically abuts against the surface of the wiping layer 41 of the cleaning roller 4, which can further inhibit the splashing of the orientedly thrown-out sewage and the squeezed-out sewage through the pressing ribs 21 in the sink during the high-speed rotation of the cleaning roller 4, so that the sewage can slowly flow out of the sewage through the mesh holes 231 in the filter piece 23 and the lower surface of the filter piece 23, and the flowed-out sewage is further guided to the sewage outlet 112 of the sink through the guide strips 22 and is further discharged to the sewage tank 52 through the sewage channel.

[0097] In some embodiments, the filter piece 23 is uniformly provided with a plurality of mesh holes 231 to isolate solid garbage with a particle size greater than the mesh hole diameter.

[0098] In the embodiment, the mesh hole diameter of the filter piece 23 can be selected according to different use scenarios, and of course, when the filter piece 23 is detachably connected to the pressing ribs 21, the user can configure different filter pieces 23 according to his own actual use habits and scenarios of the scrubber. If the user wants to use the scrubber to clean the home more cleanly, he can select a filter piece 23 with a smaller mesh hole diameter, but the frequency of deep cleaning of the filter piece 23 will also be more frequent. Conversely, although the cleaning capacity of the scrubber may be weaker, the frequency of regular cleaning of the filter piece 23 will also be lower.

[0099] Further, in some embodiments, as shown in Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 shown, the cleaning head housing further includes a first end wall 11 and a second end wall 12 for clamping the cleaning roller 4, wherein the second end wall 12 is provided with a clean water outlet 121 in the sink area, and the first end wall 11 is provided with a sewage outlet 112 in the sink area.

[0100] In the embodiment, the clean water outlet 121 is arranged on the second end wall 12 at one end of the sink, and the sewage outlet 112 is arranged on the first end wall 11 at the other end of the sink, so that the clean water transported from the clean water tank 51 can flow along the sink, and the clean water can penetrate into the surface of the wiping layer 41 of the cleaning roller 4 through the filter piece 23, the surface of the wiping layer 41 is further scraped and squeezed by the pressing ribs 21 to realize the flushing out of the fine particle garbage mixed in the wiping layer 41 with the clean water and the replacement of the sewage, and then the sewage is further guided to the sewage outlet 112 along the sink and the upper surface of the guide strips 22, and the sewage is finally discharged to the sewage tank 52 through the sewage channel.

[0101] Further, in some embodiments, as shown in Figure 11 the clean water outlet 121 does not directly face the sewage outlet 112 in the water outlet direction.

[0102] In the present embodiment, as shown in Figure 5 , a clean water outlet 121 is arranged on the second end wall 12 at one end of the water tank, and the clean water outlet 121 is arranged above the upper surface of the filter element 23, so that the clean water delivered from the clean water tank 51 can flow along the upper surface of the filter element 23. Further, the clean water outlet 121 can be circular, so that a circular pipe joint can be selected for connecting the clean water passage pipeline. Of course, the clean water outlet 121 can also be rectangular, and an appropriate pipe joint can be selected for connecting the clean water passage pipeline. Figure 6 Figure 9 As shown in Figure 11 , a sewage outlet 112 is arranged on the first end wall 11 at the other end of the water tank, and the sewage outlet 112 is arranged above the upper surface of the filter element 23. The sewage outlet 112 covers the entire width of the water tank, so that the resistance of the sewage flowing to the sewage passage due to the small pipe diameter can be reduced, and the sewage can flow more smoothly. The surface of the wiping layer 41 can be replaced by the clean water delivered from the wiping layer 41, and the clean water flowing along the upper surface of the filter element 23 can be conveniently and easily discharged into the sewage passage. Figure 5 Figure 6 Figure 9 As shown in , the clean water outlet 121 is not directly opposite the sewage outlet 112 in the water outlet direction, so that the clean water delivered from the clean water outlet 121 can not directly flow into the sewage outlet 112 along the upper surface of the filter element 23. Instead, we hope that all the clean water can pass through the filter element 23 and replace the clean water and sewage in the wiping layer 41, so as to carry away the fine particles of garbage mixed in the wiping layer 41. The scheme of the clean water outlet 121 not being directly opposite the sewage outlet 112 in the water outlet direction can improve the replacement efficiency of the clean water and the sewage.

[0103] Of course, the clean water outlet 121 and / or the sewage outlet 112 can also be arranged below the lower surface of the filter element 23. This scheme can directly flush the surface of the wiping layer 41, but it is more difficult to control the dryness of the ground after the scrubber sweeps the ground. In short, the ground will be wetter. Users can selectively adjust the positions of the clean water outlet 105 and the sewage outlet 106 at the two ends of the water tank according to their own use scenarios.

[0104] In some embodiments, as shown in Figures 5 to 7 ​​As shown, the pressing ribs 21, the guide bars 22, the upper surface of the cleaning roller 4 between the pressing ribs 21 and the guide bars 22, and the two end walls jointly form the water tank, and the water tank is divided into a wet area (not marked in the figure) and a semi-wet area F by a filter 23. The wet area is jointly enclosed by the pressing ribs 21, the guide bars 22, the upper surface of the cleaning roller 4 between the pressing ribs 21 and the guide bars 22, the lower surface of the filter 23, and the two end walls. During the working process of the scrubber, no matter how much the water flow in the water tank is, the wet area is always wet, and it is natural to easily cause the deposition of sticky garbage. The semi-wet area F is jointly enclosed by the pressing ribs 21, the guide bars 22, the upper surface of the filter 23, the lower surface of the top wall of the pressing cover body between the pressing ribs 21 and the guide bars 22, and the two end walls. During the working process of the scrubber, the water pump of the scrubber intermittently sprays water from the clean water tank 51 to the water tank. When the water flow is not large, the side wall of the pressing rib 21, the side wall of the guide bar 22, and most of the area of the top wall of the pressing cover body in the semi-wet area F are dry. At this time, only the upper surface of the filter 23 has the opportunity to be wet, and only the upper surface of the filter 23 is more likely to cause the deposition of sticky garbage. In daily use, if a certain amount of sticky garbage is deposited in the wet area and the semi-wet area F, the cleaning efficiency of the scrubber will be affected, and the user needs to remove the pressing cover assembly 2 in time to clean the wet area and the semi-wet area F.

[0105] In some embodiments, the filter 23 is arranged at one end of the water tank close to the sewage tank 52. Specifically, by arranging the filter 23 at one end of the water tank close to the sewage tank, the sewage at one end of the cleaning roller 4 close to the sewage tank interface can be reduced without being filtered into the sewage tank.

[0106] In some embodiments, the filter 23 is arranged parallel to the pressing ribs 21 and the guide bars 22, that is, the filter 23 is not connected to the pressing ribs 21 and the guide bars 22. The filter 23 divides the water tank formed between the guide bars 22 and the pressing ribs 21 into two water tanks, and the water tank close to the guide bars 22 is communicated with the sewage tank 52. After the pressing ribs 21 press the cleaning roller 4, excessive water on the cleaning roller 4 flows into the water tank formed between the filter 23 and the guide bars 22 through the filter 23, and then flows into the sewage tank 52.

[0107] In some embodiments, as shown in FIG. 6, the filter 23 is arranged at one end of the water tank close to the sewage tank 52. Figures 3 to 7 , Figure 10As shown, the distance between the end of the pressing rib 21 close to the cleaning roller 4 and the end close to the pressing cover body 20 is greater than the distance between the end of the guide strip 22 close to the cleaning roller 4 and the end close to the pressing cover body 20, in other words, the pressing rib 21 presses the wiping layer 41 more deeply and the guide strip 22 presses the wiping layer 41 more shallowly. This design makes it easier for the pressing rib 21 to scrape and press the wiping layer 41 to guide the sewage out, and the guide strip 22 is more easily in elastic abutment with the wiping layer 41 to guide the pressed-out sewage to the sewage outlet 112.

[0108] In some embodiments, as Figures 10 to 12 As shown, the top of the pressing cover body 20 is provided with an opening (not marked in the figure) opposite the area of the water tank, the pressing cover assembly 2 further comprises a water sealing and air permeable cover 26 connected to the top opening of the pressing cover body 20, the water sealing and air permeable cover 26 comprises a cover plate 261 and a sealing eave 262, and the cover plate 261 is further provided with an observation window 263, and the sealing eave 262 of the water sealing and air permeable cover 26 is just covered on the top opening of the pressing cover body 20. When the user drags the cleaning head assembly to mop the ground, in order to prevent the clean water and sewage in the water tank from being splashed out of the water tank and falling on the ground after being stirred, the sealing eave 262 is provided around the cover plate 261 of the water sealing and air permeable cover 26, and the sealing eave 262 just seals the top opening of the pressing cover body 20. When the user uses the scrubber for a period of time and needs to further clean the water tank, the user can open the water sealing and air permeable cover 26 to flush the inside of the water tank. The observation window 263 is transparent, so that the user can directly see the flow of clean water and sewage in the water tank through the observation window 263 without having to take off the water sealing and air permeable cover 26 one by one.

[0109] The second aspect, as Figures 1 to 4 As shown, the present application further provides a cleaning head assembly comprising the pressing cover assembly 2 of the first aspect, a cleaning head shell 1, a cleaning roller 4 and a water tank assembly 5, the cleaning head shell 1 has a first end wall 11 and a second end wall 12 clamping the cleaning roller 4, and both the end walls are provided with a water flow channel connecting the water tank of the pressing cover assembly; the cleaning roller 4 is clamped between the two end walls of the cleaning head shell, the cleaning roller 4 comprises a driving motor 4a mounted on one end wall and a cleaning roller (not marked in the figure) sleeved on the output end of the driving motor, and the outer surface of the cleaning roller is sleeved with a wiping layer 41; the water tank assembly 5 can be installed, taken and placed from one end wall of the cleaning head shell 1, and comprises a clean water tank 51 and a sewage tank 52 connecting the water tank of the pressing cover assembly; wherein the pressing cover assembly 2 is detachably covered on the cleaning head shell 1.

[0110] Specifically, the cleaning head assembly comprises a cleaning head housing 1, a driving motor 4a mounted on an end wall of the cleaning head housing 1, a cleaning roller 4 sleeved on the driving motor 4a, a water tank assembly 5 mounted and removed through one side of the cleaning head housing 1, a shovel strip assembly 6 slidably mounted and removed at the bottom of the cleaning head housing 1 and used to guide the garbage to be lifted by the cleaning roller 4, and a brush assembly 3 mounted in the cleaning head housing 1 and driven synchronously by the cleaning roller 4. The driving motor 4a drives the cleaning roller 4 to rotate, thereby driving the brush assembly 3 to rotate synchronously. The brush assembly 3 is used to sweep the solid garbage and sticky garbage lifted by the cleaning roller 4.

[0111] In a third aspect, the application further provides a scrubber, which comprises the cleaning head assembly and a handle (not shown in the drawings) fixedly connected with the cleaning head assembly.

[0112] Specifically, the specific working mode of the scrubber provided by the application is as follows: the scrubber is started, the driving motor 4a starts to work, and the water circuit works synchronously. When the driving motor 4a rotates, the cleaning roller 4 rotates, thereby driving the brush assembly 3 to rotate. After the water circuit works, clean water is delivered to the surface of the cleaning roller 4 through the clean water tank 51 of the water tank assembly 5 and a clean water pipeline (not shown in the drawings), thereby wetting the surface of the cleaning roller 4. Meanwhile, the wiping layer 41 of the cleaning roller 4 rolls on the ground to clean the ground. The shovel strip assembly 6 is slidably mounted on the cleaning head housing 1 and closely arranged behind the cleaning roller 4. The garbage collecting assembly 7 is arranged behind the cleaning roller 4 and below the brush assembly 3. When the wiping layer 41 of the cleaning roller 4 rolls on the ground to clean the ground, the garbage on the ground is scooped up by the shovel strip assembly 6, and through the gap between the shovel strip assembly 6 and the wiping layer 41 of the cleaning roller 4 and the friction of the wiping layer 41 of the cleaning roller 4, the garbage is brought into the garbage collecting assembly 7. Meanwhile, the brush assembly 3 is in contact with the wiping layer 41 of the cleaning roller 4, the brush assembly 3 sweeps the garbage remaining on the wiping layer 41 of the cleaning roller 4, and sweeps the garbage into the garbage collecting assembly 7, thereby realizing the collection of the garbage on the ground. In addition, when the scrubber works, clean water is continuously delivered to the surface of the wiping layer 41 of the cleaning roller 4, the clean water after washing the wiping layer 41 of the cleaning roller 4 is replaced into sewage by the filtering piece 23, and the sewage is delivered to the sewage tank 52 of the water tank assembly 5 through a water tank.

[0113] The above merely describes the specific implementation of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the application, and these modifications or replacements shall be covered in the protection scope of the application. Therefore, the protection scope of the application shall be subject to the protection scope of the claims.
