Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to an open-type sink, a cleaning head assembly, and a floor scrubber. Background Technology

[0002] As living standards gradually improve, people's demands for quality of life are also increasing. More and more people are laying beautiful flooring or tiles on their homes. When the flooring or tiles get dirty and need cleaning, the traditional method is to use brooms, mops, or scouring pads. This method is time-consuming and laborious, and it doesn't increase people's interest in cleaning, which is not conducive to maintaining a clean indoor environment. Therefore, floor scrubbers have emerged. A floor scrubber is a cleaning appliance suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site.

[0003] Currently, the wastewater generated by floor scrubbers typically flows into a wastewater tank through a water tank inside the machine. However, the wastewater often contains undissolved particles, which can easily clog the wastewater tank. Furthermore, once a certain amount of debris accumulates in the water tank, the lack of air circulation can cause the cleaning rollers enclosed in the tank to develop an unpleasant odor when the user uses the scrubber for the first time after a long period of inactivity. This results in a poor customer experience as the odor is carried over to the cleaned floor. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an open-type water tank, a cleaning head assembly, and a floor scrubber, aiming to solve the problems of easy clogging of the wastewater tank and foul odor in the water tank of existing floor scrubbers when not in use for extended periods.

[0060] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.

[0061] The scheme of the present application will be described in detail below in conjunction with the accompanying drawings.

[0062] As analyzed in the background art of the present application, the existing sewage tank of the scrubber is easy to be blocked and smelly in the sink for a long time without water. To solve the above technical problems, for this purpose, in a first aspect, a sewage tank for a scrubber is provided, which comprises a sewage tank body and a sewage tank cover, wherein the sewage tank cover is arranged on the sewage tank body and is provided with a sewage tank cover opening. Figures 1 to 7As shown, the embodiment of the present application provides an open water tank, which is arranged inside the cleaning head shell 1 of the scrubber, is arranged above the cleaning roller 4, and comprises a pressing rib 101, a guide strip 102, a connecting piece 103, and a breathable cover 2. The pressing rib 101 and the guide strip 102 are arranged on the inner side of the top wall of the cleaning head shell 1, protrude towards the cleaning roller 4, and abut against the cleaning roller 4. The connecting piece 103 connects the pressing rib 101 and the guide strip 102, is close to the lower surface of the cleaning roller 4, and is uniformly provided with filter through holes 10311. The breathable cover 2 covers the strip-shaped opening (not marked in the drawing) of the top wall of the cleaning head shell 1, which is opposite to the region of the connecting piece 103, can inhibit the liquid water from overflowing outward, and is breathable. The pressing rib 101, the guide strip 102, the upper surface of the cleaning roller 4 between the pressing rib 101 and the guide strip 102, and the two end walls (11, 12) of the cleaning head shell 1 jointly enclose the open water tank (not marked in the drawing), and the two ends of the open water tank are connected with the fresh water tank 51 and the sewage tank 52 of the scrubber respectively. When the user cleans the water tank, only the breathable cover 2 needs to be removed, so that the cleaning is convenient. When the user does not use the scrubber for a long time, the open water tank is not easy to smell due to the fact that the breathable cover 2 can be breathable outward.

[0063] The cleaning head shell 1 provided by the embodiment comprises a cleaning head shell body 10, a first end wall 11, a second end wall 12, and a cleaning roller cover 13. The cleaning roller cover 13 is arranged on the cleaning head shell body 10, and is used for covering the cleaning roller 4 of the scrubber. The cleaning head shell body 10 comprises a pressing rib 101, a guide strip 102, and a connecting piece 103. The pressing rib 101 and the guide strip 102 are arranged on the cleaning head shell body 10, abut against the cleaning roller 4 arranged in the cleaning head shell 1, and form a water tank. The pressing rib 101 is used for extruding excess water on the cleaning roller 4. The guide strip 102 is used for blocking the extruded sewage on the cleaning roller 4 from flowing into the garbage collection assembly 7. When the cleaning roller 4 cleans the ground, the pressing rib 101 contacts and extrudes the cleaning roller 4. Meanwhile, the connecting piece 103 connected between the pressing rib 101 and the guide strip 102 can filter particles in the sewage, so as to prevent the sewage from entering the sewage tank, and thus avoids the blockage of the sewage tank. The cleaning roller cover 13 further comprises a locking mechanism (not marked in the drawing) arranged on the cleaning roller cover 13. When the user needs to maintain and clean the water tank, the cleaning roller cover 13 can be easily removed from the cleaning head shell 1 by unlocking. When the cleaning roller cover 13 needs to be installed on the cleaning head shell 1, the cleaning head shell 1 can be stably covered through multiple locking points (not marked in the drawing). The cleaning roller cover 13 is further provided with a long hollow groove (not marked in the drawing). A part of the breathable cavity 23 of the breathable cover 2 passes through the hollow groove.

[0064] In the embodiment, the connecting piece 103 arranged between the pressing rib 101 and the guide strip 102 is mainly used for filtering sewage, preventing particles in the sewage from flowing into the sewage tank in the scrubber, that is, the connecting piece 103 can be arranged between the pressing rib 101 and the guide strip 102 and located before the sewage tank inlet, and the specific actual position can be selected according to the actual application, which is not limited in the embodiment.

[0065] In one or some optional embodiments, the cross section of the connecting piece 103 gradually reduces from the connecting position of the guide strip 102 to the surface of the cleaning roller 4 in the direction of the pressing rib 101.

[0066] In the embodiment, as shown in Figure 3 , Figure 4 the cross section of the connecting piece 103 gradually reduces from the connecting position of the guide strip 102 to the surface of the cleaning roller 4 in the direction of the pressing rib 101 until the connecting piece 103 is connected to the pressing rib 101, and the pressing rib 101 elastically abuts against the surface of the cleaning roller. Preferably, the connecting position of the connecting piece 103 to the pressing rib 101 is higher than the surface of the cleaning roller 4, so as to prevent the gap at the connecting position from storing dirt in the use of the scrubber. The cross section of the connecting piece 103 gradually reduces from the connecting position of the guide strip 102 to the surface of the cleaning roller 4 in the direction of the pressing rib 101, so that the front side of the pressing rib 101 can have a certain buffer space for the wiping layer 41 of the cleaning roller 4 which is not extruded by the pressing rib 101 in the direction of the rotation of the cleaning roller, and the wiping layer 41 can slowly and smoothly transition in the process of changing from the state of not being extruded to the state of being extruded to the greatest extent, so as to reduce the current of the driving motor 4a of the scrubber in the working state.

[0067] In one or some optional embodiments, the cross section of the connecting piece 103 gradually reduces from the middle to the surface of the cleaning roller 4 in the direction of the pressing rib 101, and the cross section of the connecting piece 103 keeps constant from the middle to the surface of the cleaning roller 4 in the direction of the guide strip 102.

[0068] In the embodiment, as shown in Figure 3 , Figure 4As shown, the cross section of the connecting piece 103 gradually reduces from the middle part to the distance from the surface of the cleaning roller 4 in the direction of the pressing rib 101 until the connecting piece 103 is connected to the pressing rib 101, and the pressing rib 101 elastically abuts against the surface of the cleaning roller. Preferably, the connecting position of the connecting piece 103 to the pressing rib 101 is higher than the surface of the cleaning roller 4, so that the gap at the connecting position can be prevented from storing dirt during the use of the scrubber. The cross section of the connecting piece 103 gradually reduces from the middle part to the distance from the surface of the cleaning roller 4 in the direction of the pressing rib 101, so that the front side of the pressing rib 101 of the wiping layer 41 of the cleaning roller 4 can have a certain buffer space when viewed in the direction of the rotation of the cleaning roller, and the wiping layer 41 can slowly and smoothly transition during the change between the state of not being pressed and the state of being pressed to the maximum extent, so as to reduce the current of the driving motor 4a of the scrubber in the working state of driving the cleaning roller 4 to rotate. The reason for starting from the middle part is to ensure that the lower surface of the connecting piece from the connecting position of the connecting piece 103 to the guide strip 102 to the middle part of the connecting piece 103 is higher than the surface of the cleaning roller 4, that is, a gap is left between the lower surface of the connecting piece 103 and the surface of the cleaning roller 4, so that the clean water and sewage flowing from the filtering through hole 10311 continue to flush the surface of the wiping layer 41 in the gap with a certain initial speed, which is more conducive to improving the cleaning efficiency.

[0069] In one or some optional embodiments, the cross section of the connecting piece 103 is Z-shaped, the upper surface of the upper end 1033 of the Z-shaped connecting piece 103 leaves a gap with the top wall of the cleaning head shell 1, and the lower surface of the lower end 1031 of the Z-shaped connecting piece 103 leaves a gap with the cleaning roller 4.

[0070] In the embodiment, as shown, Figures 3 to 8 the cross section of the connecting piece 103 is Z-shaped, the upper surface of the upper end 1033 of the Z-shaped connecting piece 103 leaves a gap with the top wall of the cleaning head shell 1, and the lower surface of the lower end 1031 of the Z-shaped connecting piece 103 leaves a gap with the cleaning roller 4. As shown, Figure 3 , Figure 4 As shown in combination with Figures 5 to 8 , the overall open water tank is open at the top, and the breathable cover 2 is combined with the top opening of the open water tank. Here, the top wall of the cleaning head shell 1 actually refers to the breathable cover 2. The upper surface of the upper end 1033 of the Z-shaped connecting piece 103 leaves a gap with the breathable cover 2, so that the air in the upper space of the water tank can flow more easily at any time, so that the water tank is not easy to smell. The lower surface of the lower end 1031 of the Z-shaped connecting piece 103 leaves a gap with the cleaning roller 4, so that the clean water and sewage flowing from the filtering through hole 10311 continue to flush the surface of the wiping layer 41 in the gap with a certain initial speed, which is more conducive to improving the cleaning efficiency.

[0071] In one or some optional embodiments, the Z-shaped lower end 1031 of the cross section of the connecting piece 103 points to the pressing rib 101 in an arc shape with gradually reduced distance from the surface of the cleaning roller 4.

[0072] In the present embodiment, as shown in Figure 3 , Figure 4 the Z-shaped lower end 1031 of the cross section of the connecting piece 103 points to the pressing rib 101 in an arc shape with gradually reduced distance from the surface of the cleaning roller 4, so that the wiping layer 41 of the cleaning roller 4 can have a certain buffer space on the front side of the pressing rib 101 that has not been extruded by the pressing rib 101, as viewed along the rotation direction of the cleaning roller, allowing the wiping layer 41 to transition smoothly during the change between the two states of not being extruded and being extruded to the maximum extent, so as to reduce the current of the driving motor 4a of the scrubber in the working state.

[0073] In one or some optional embodiments, the Z-shaped upper end 1033 and the Z-shaped vertical section 1032 of the connecting piece 103 gradually tighten towards the guide bar 102 from at least one of the two end walls (11, 12) approaching.

[0074] In some embodiments, as shown in Figure 5 the Z-shaped upper end 1033 and the Z-shaped vertical section 1032 of the connecting piece 103 gradually tighten towards the guide bar 102 from the second end wall 12 approaching. In combination with Figure 3 , Figure 4 , it can be seen that the frontmost surface of the Z-shaped vertical section 1032 of the connecting piece leaves a gap with the facade of the guide bar 102, which we call the large-particle garbage accommodation area J. The cross-sectional width of the large-particle garbage accommodation area J gradually decreases as it advances towards the guide bar 102, until the width size is reduced to zero, at which point the cross section of the connecting piece 103 becomes L-shaped. This can stagger the water outlet 121 on the second end wall 12 and the sewage outlet 111 on the first end wall 11 in the water outlet direction, so as to prevent clean water from flowing directly along the upper surface of the connecting piece 103 into the sewage outlet 111, thereby improving the displacement efficiency of clean water and sewage in the water tank, and further improving the cleaning efficiency of the scrubber.

[0075] In some embodiments, as shown in Figure 8As shown, the connecting piece 103 gradually tightens towards the guide strip 102 from the Z-shaped upper end 1033 and the Z-shaped vertical section 1032 close to the two end walls (11, 12), until the cross section changes from Z-shaped to L-shaped. In combination with Figure 3 , Figure 4 , Figure 6 As shown, the connecting piece 103 gradually tightens towards the guide strip 102 from the Z-shaped upper end 1033 and the Z-shaped vertical section 1032 close to the two end walls (11, 12), until the cross section changes from Z-shaped to L-shaped. In combination with

[0076] In one or some optional embodiments, the pressing rib 101 is integrally formed with the cleaning head shell body 10, or is detachably connected with the cleaning head shell body 10.

[0077] In the present embodiment, as Figures 2 to 8As shown, the cleaning head housing body 10 can be formed by a mold during the manufacturing process to form a plurality of protrusions on the surface thereof, which can be directly used as the pressing ribs 101 for pressing the cleaning roller 4. The structure of the end of the pressing ribs 101 elastically abutting against the cleaning roller 4 matches the cleaning roller 4, that is, the end of the pressing ribs 101 abutting against the cleaning roller 4 can be an arc-shaped end. Of course, the end of the pressing ribs 101 abutting 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 specifically limited in the present embodiment. Preferably, the pressing ribs 101 are straight lines with a single cross-sectional shape and are parallel to the axis of the cleaning roller 4. Further, the pressing ribs 101 can be tightened toward the inside of the water tank (not marked in the drawing) near the two end walls, 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 toward the axial side of the cleaning roller 4. This "tightening" has two meanings. The first meaning is that the pressing ribs 101 are tightened toward 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 ribs 101 extend toward the axis of the cleaning roller 4 to increase the interference fit amount of the elastic abutting. The double meanings of "tightening toward the inside of the water tank" can further improve the water leakage prevention capability of the entire water tank under any angle of use.

[0078] In the present embodiment, the cleaning head shell body 10 can be formed by a mold during the manufacturing process to reserve an interface for mounting the pressing rib 101 on the surface thereof, and the pressing rib 101 can be detachably connected to the cleaning head shell body 10 by using the mounting interface and cooperating with relevant fasteners if necessary. The structure of the end of the pressing rib 101 that elastically abuts against the cleaning roller 4 matches the cleaning roller 4, that is, the end of the pressing rib 101 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 pressing rib 101 and the wiping layer 41 of the cleaning roller 4 will be worn to a certain extent due to the elastic abutment therebetween during the working process, and the wear will seriously affect the cleaning efficiency of the scrubber when reaching a certain extent. The cleaning roller 4 itself is positioned as a consumable material, and should be replaced after being used for a period of time. However, the wear degree of the pressing rib 101 is usually small due to the hardness thereof being 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 extent, the cleaning efficiency of the scrubber cannot be restored even if the cleaning roller 4 is replaced, and the pressing rib 101 should be replaced at this time. Of course, the material for manufacturing the pressing rib 101 is not limited to non-metallic materials such as hard plastic, and hard metal materials with moderate cost can also be used to manufacture the pressing rib 101, such as aluminum alloy, magnesium alloy, magnesium-aluminum alloy, zinc alloy, stainless steel, etc. As for the interface form for mounting the pressing rib 101 to the cleaning head shell body 10, the skilled in the art can use common interface structures such as flat stepped structures, interfaces with grooves or protrusions, etc., which are not limited in the present embodiment.

[0079] In one or some optional embodiments, the guide bar 102 is integrally formed with the cleaning head shell body 10, or is detachably connected to the cleaning head shell body 10.

[0080] In the present embodiment, the cleaning head housing body 10 can be formed by a mold during manufacturing to form a plurality of protrusions on its surface, which can directly serve as the guide bars 102 for blocking the flow of the squeezed dirty water on the wiping layer 41 of the cleaning roller 4 into the garbage collecting assembly 7. The end of the guide bar 102 that elastically abuts against the cleaning roller 4 can also be matched with the cleaning roller 4, that is, the end of the guide bar 102 that abuts against the cleaning roller 4 can be an arc-shaped end. Preferably, in order to increase the ability of the guide bar 102 to suppress the cleaning roller 4 from throwing out liquid outward during high-speed rotation, the end of the guide bar 102 that elastically abuts against the wiping layer 41 can be provided as a crescent-shaped end (not shown in the drawings) with two pointed ends that elastically abut against the wiping layer 41 and a middle part that arches outward 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 of the guide bar 102 that elastically abuts against the wiping layer 41 can only have one pointed end that elastically abuts against the wiping layer 41 near the end of the pressing rib 101. The other pointed end can facilitate the brush assembly 3 in the cleaning head assembly to throw out the brushed solid and sticky garbage into the garbage collecting assembly 7 during high-speed rotation, avoiding the garbage being thrown back onto the surface of the wiping layer 41 by the brush assembly after one rotation. Of course, the end of the guide bar 102 that elastically abuts against the wiping layer 41 can also be designed into any shape that can achieve the above functions, such as a sickle shape or a wedge shape, which are not limited in the present embodiment.

[0081] In the present embodiment, as shown in Figures 3 to 4 , Figure 6 In the present embodiment, the cleaning head housing body 10 can be formed by a mold during manufacturing to form a plurality of protrusions on its surface, which can directly serve as the guide bars 102 for blocking the flow of the squeezed dirty water on the wiping layer 41 of the cleaning roller 4 into the garbage collecting assembly 7. The end of the guide bar 102 that elastically abuts against the cleaning roller 4 can also be matched with the cleaning roller 4, that is, the end of the guide bar 102 that abuts against the cleaning roller 4 can be an arc-shaped end. Preferably, in order to increase the ability of the guide bar 102 to suppress the cleaning roller 4 from throwing out liquid outward during high-speed rotation, the end of the guide bar 102 that elastically abuts against the wiping layer 41 can be provided as a crescent-shaped end (not shown in the drawings) with two pointed ends that elastically abut against the wiping layer 41 and a middle part that arches outward 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 of the guide bar 102 that elastically abuts against the wiping layer 41 can only have one pointed end that elastically abuts against the wiping layer 41 near the end of the pressing rib 101. The other pointed end can facilitate the brush assembly 3 in the cleaning head assembly to throw out the brushed solid and sticky garbage into the garbage collecting assembly 7 during high-speed rotation, avoiding the garbage being thrown back onto the surface of the wiping layer 41 by the brush assembly after one rotation. Of course, the end of the guide bar 102 that elastically abuts against the wiping layer 41 can also be designed into any shape that can achieve the above functions, such as a sickle shape or a wedge shape, which are not limited in the present embodiment. Figure 6 As shown in Figures 3 to 4As shown, the guide strip 102 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 two side walls of the clamping end elastically clamped with the clamping groove are provided with elastic barb structures (not shown in the drawing), which facilitate the user to easily clamp the clamping end into the clamping groove when replacing the guide strip 102. Preferably, the guide strip 102 is a straight line with a single cross-sectional shape and is parallel to the axis of the cleaning roller 4. Further, the guide strip 102 can be tightened towards the inside of the sink near the two end walls, so as to prevent the entire cleaning head assembly from leaking due to excessive water pressure at the elastic abutting position of the sink and the end wall when the cleaning roller 4 is tilted to one side of the axis of the cleaning roller 4. This "tightening" has two meanings, which are the same as the "tightening at both ends" of the pressure rib 101 discussed in the foregoing embodiment, which will not be repeated here.

[0082] In one or some optional embodiments, one end of the connecting piece 103 is connected to the pressure rib 101.

[0083] In the present embodiment, the connecting piece 103 is detachably connected at the end of the pressure rib 101 abutting the cleaning roller 4 and towards the side of the guide strip 102. The lower surface of the connecting piece 103 extends towards the guide strip 102 along the surface of the roller assembly. The connecting piece 103 can filter the large particle garbage and undissolved particle garbage in the garbage and sewage brought into the sink by the cleaning roller 4. Inevitably, some sticky garbage will accumulate on the upper and lower surfaces of the connecting piece 103 over time. The detachable connecting piece 103 design facilitates the user to detach the connecting piece 103 for thorough cleaning every interval of time when the simple large water flushing mode has failed to thoroughly clean the connecting piece 103, so as to maintain the health and hygiene of the user's home environment.

[0084] In one or some optional embodiments, the connecting piece 103 extends from the side of the pressure rib 101 towards the guide strip 102, the lower surface of the connecting piece 103 leaves a gap with the surface of the cleaning roller 4, and the connecting piece 103 is detachably connected with the pressure rib 101.

[0085] In this embodiment, the connecting piece 103 is detachably connected at the end of the pressure rib 101 abutting against the cleaning roller 4 and on the side facing the guide strip 102. A gap is left between the lower surface of the connecting piece 103 and the upper surface of the wiping layer 41 of the cleaning roller 4, and the connecting piece 103 extends towards the guide strip 102. A gap (not shown in the figure) is left between the lower surface of the connecting piece 103 and the upper surface of the wiping layer 41, forming a gap space, which allows the sewage squeezed out by the pressure rib 101 to further flush the upper surface of the wiping layer 41, and prevents fine particle garbage from depositing on the lower surface of the connecting piece 103. On the other hand, the gap space allows air in the space to circulate, so that even when the scrubber is not in operation, the garbage deposited in the space will not stink due to long-term sealing. The connecting piece 103 has the functions described in the foregoing embodiments, which will not be described here.

[0086] Further, in this embodiment, the extending end of the connecting piece 103 (not shown in the figure) is provided with a connecting piece extending hook portion (not shown in the figure) extending away from the surface of the roller assembly along the normal direction. The frontmost end surface of the hook portion leaves a gap (not shown in the figure) with the vertical surface of the guide strip 102.

[0087] In this embodiment, the hook portion of the connecting piece 103 extends away from the surface of the roller assembly along the normal direction to form a connecting piece extending hook portion (not shown in the figure). When the user is using the scrubber to clean a water-logged floor, and the water sucked up by the cleaning roller 4 is squeezed out by the pressure rib 101 to form a sewage flow in the sump that is too large, the connecting piece extending hook portion can prevent the sewage from overflowing the top end of the connecting piece extending hook portion extending away from the surface of the roller assembly along the normal direction, so that the squeezed-out sewage must pass through the filter of the connecting piece 103 before being guided to the sewage outlet 111 at one end of the sump to be further transported to the sewage tank 52, thereby preventing the sewage channel from being blocked by the sewage bypassing the connecting piece 103. As shown in Figures 3 to 8 The connecting piece extending hook portion continues to extend in a direction parallel to the upper surface of the wiping layer 41 until it is connected to the guide strip 102. The portion between the connecting piece extending hook portion and the guide strip 102 is referred to as a connecting piece extending connecting portion (not shown in the figure), which reliably connects the connecting piece extending hook portion and the guide strip 102. Of course, not all the opposite portions of the connecting piece extending hook portion and the guide strip 102 need to be reliably connected. The connecting piece extending connecting portion can connect the opposite portions of the connecting piece extending hook portion and the guide strip 102 at intervals along the axial direction of the cleaning roller 4, and the interval portion forms the open channel 10331 of the sump. Figure 3 、 Figure 4As shown, the front end surface of the extension hook of the connecting piece leaves a gap with the vertical surface of the guide strip 102, and we call this vertical gap space a large particle garbage containing area J. In this way, a small amount of large particle garbage that is brought up by the cleaning roller 4 and not brushed off by the brush can be hoisted into the water tank. This gap space can often contain these large particle garbage and "stay" while being constantly turned over. When the gap between the lower surface of the connecting piece 103 and the wiping layer 41 is smaller than the diameter of the large particle garbage, the large particle garbage is brought to the open channel 10331 with the gap space volume slowly increasing, and is "restricted" in the space, so as not to be stuck in the narrow gap between the lower surface of the connecting piece 103 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 connecting piece 103 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.

[0088] In one or some optional embodiments, as shown in Figures 2 to 8 As shown, the connecting piece 103 is integrally formed with the cleaning head shell body 10.

[0089] Similarly, the protrusion formed in the manufacturing process of the cleaning head shell body 10 can also be used as the connecting piece 103 for filtering particle garbage in sewage. After the cleaning roller 4 is installed in the cleaning head shell 1, the protrusion also abuts against the cleaning roller 4. Meanwhile, a plurality of filtering holes 10311 are arranged on the protrusion. The sewage in the water tank can be further filtered by the filtering holes 10311. The filtered sewage can be further transported to the sewage tank 52 through the sewage outlet 111 of the water tank, so as to prevent the sewage channel from being blocked.

[0090] It should be noted that the filtering holes 10311 on the connecting piece 103 can be formed in the molding process of the cleaning head shell body 10, or can be machined after the cleaning head shell body 10 is molded. They can be selected according to actual application, and the present embodiment is not limited in this regard.

[0091] It should also be noted that the reinforcing ribs 101, the guide strip 102 and the connecting piece 103 can be simultaneously single-shot molded in the molding process of the cleaning head shell body 10. Of course, they can also be sequentially molded by multiple-shot molding. That is, the reinforcing ribs 101, the guide strip 102, the connecting piece 103 and the cleaning head shell body 10 can be integrally molded.

[0092] In one or some optional embodiments, one end of the connecting piece 103 is arranged on the cleaning head shell body 10, and the other end abuts against the cleaning roller 4.

[0093] In the embodiment, the free end of the connecting piece 103 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 sewage squeezed out through the pressing ribs 101 in the sink during the high-speed rotation of the cleaning roller 4, so that the sewage can slowly flow out through the filtering through holes 10311 in the connecting piece 103 and the lower surface of the connecting piece 103, and the flowing-out sewage is further guided to the sewage outlet 111 of the sink through the guide strips 102, and the sewage is further discharged to the sewage tank 52 through the sewage channel.

[0094] In one or some optional embodiments, the connecting piece 103 is uniformly provided with a plurality of filtering through holes 10311 to isolate solid garbage with a particle size greater than the hole diameter of the filtering through holes.

[0095] In the embodiment, as shown in Figures 3 to 8 , the hole diameter of the filtering through holes 10311 of the connecting piece 103 can be selected according to different use scenarios to have connecting pieces 103 with different filtering through hole diameters. Of course, in the case that the connecting piece 103 is detachably connected to the pressing ribs 101, the user can configure different connecting pieces 103 according to different scenarios according to his / her actual use habit and scenario of the scrubber. If the user wants to use the scrubber to clean the home more cleanly, he / she can select the connecting piece 103 with a smaller filtering through hole diameter, but the deep cleaning of the connecting piece 103 also needs to be more frequent. On the contrary, although the cleaning capacity of the scrubber can be weaker, the frequency of the regular cleaning of the connecting piece 103 will also be lower.

[0096] Further, in some embodiments, as shown in Figure 3 , Figure 5 , Figure 6 , Figure 7 , the cleaning head housing further comprises 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 111 in the sink area.

[0097] In the embodiment, as shown in Figure 3 , the clean water outlet 121 is arranged on the second end wall 12 at one end of the sink, and as shown in Figure 6 , the sewage outlet 111 is arranged on the first end wall 11 at the other end of the sink, so as to facilitate the flowing of the clean water delivered from the clean water tank 51 along the sink, and the clean water can penetrate into the surface of the wiping layer 41 of the cleaning roller 4 through the connecting piece 103, the surface of the wiping layer 41 is further scraped and squeezed by the pressing ribs 101, so as to realize the flushing 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 111 along the sink and the upper surface of the guide strips 102, and the sewage is finally discharged to the sewage tank 52 through the sewage channel.

[0098] Further, in some embodiments, as shown in Figure 3 , Figures 5 to 7 the clean water outlet 121 is not directly opposite the dirty water outlet 111 in the water outlet direction.

[0099] In the present embodiment, as shown in Figure 3 the clean water outlet 121 is arranged on the second end wall 12 at one end of the sink, and is arranged at a position higher than the upper surface of the connecting piece 103, so that the clean water delivered from the clean water tank 51 can flow along the upper surface of the connecting piece 103. 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. As shown in Figure 6 , Figure 7 the dirty water outlet 111 is arranged on the first end wall 11 at the other end of the sink, and is arranged at a position higher than the upper surface of the connecting piece 103. The dirty water outlet 111 covers the entire width of the sink, so that the resistance of the dirty water flowing to the dirty water passage due to a small pipe diameter can be reduced, and the dirty water can flow more smoothly. After the dirty water delivered from the surface of the wiping layer 41 flows along the upper surface of the connecting piece 103, it can be conveniently and easily discharged into the dirty water passage. As shown in Figure 7 in combination with Figure 3 , Figure 6 it can be seen that the clean water outlet 121 is not directly opposite the dirty water outlet 111 in the water outlet direction. In this way, the clean water delivered from the clean water outlet 121 can not directly flow into the dirty water outlet 111 along the upper surface of the connecting piece 103. Instead, we hope that all the clean water passes through the connecting piece 103 to perform clean water and dirty water replacement on the wiping layer 41, so as to carry away the fine particles of garbage mixed in the wiping layer 41. The scheme that the clean water outlet 121 is not directly opposite the dirty water outlet 111 in the water outlet direction can achieve a higher clean water and dirty water replacement efficiency.

[0100] Of course, the clean water outlet 121 and / or the dirty water outlet 111 can also be arranged at a position lower than the lower surface of the connecting piece 103. In this way, the flushing of the surface of the wiping layer 41 is more direct. However, in this way, it is more difficult to control the dryness of the ground after the scrubber sweeps the ground. In other words, the ground will be wetter. Users can selectively adjust the positions of the clean water outlet 121 and the dirty water outlet 111 at the two ends of the sink according to their own use scenarios.

[0101] In some embodiments, as shown in Figures 3 to 7As shown, the pressing ribs 101, the guide bars 102, the upper surface of the cleaning roller 4 between the pressing ribs 101 and the guide bars 102, and the two end walls jointly form the water tank, and a connecting piece 103 is arranged in the water tank. The water tank is divided into a wetting area (not marked in the figure) and a semi-wetting area F by the connecting piece 103. The wetting area is jointly enclosed by the pressing ribs 101, the guide bars 102, the upper surface of the cleaning roller 4 between the pressing ribs 101 and the guide bars 102, the lower surface of the connecting piece 103, and the two end walls. During the working process of the scrubber, the wetting area is always wet, and it is natural to easily cause the deposition of sticky garbage, regardless of the water flow in the water tank. The semi-wetting area F is jointly enclosed by the pressing ribs 101, the guide bars 102, the upper surface of the connecting piece 103, the lower surface of the top wall of the cleaning head shell between the pressing ribs 101 and the guide bars 102, 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 101, the side wall of the guide bar 102, and most of the area of the top wall of the cleaning head shell in the semi-wetting area F are dry. At this time, only the upper surface of the connecting piece 103 has the opportunity to be wet, and only the upper surface of the connecting piece 103 is more likely to cause the deposition of sticky garbage. In daily use, if a certain amount of sticky garbage is deposited in the wetting area and the semi-wetting area F, the cleaning efficiency of the scrubber will be affected, and the user needs to remove the breathable cover 2 in time to clean the wetting area and the semi-wetting area F.

[0102] In some embodiments, the connecting piece 103 is arranged at one end of the water tank close to the sewage tank 52. Specifically, by arranging the connecting piece 103 at one end of the water tank close to the sewage tank 52, the sewage at one end of the cleaning roller 4 close to the sewage tank interface can be reduced to flow into the sewage tank 52 without filtering.

[0103] In some embodiments, as shown in Figures 2 to 8 The connecting piece 103 is arranged parallel to the pressing ribs 101 and the guide bars 102, that is, the connecting piece 103 is not connected to the pressing ribs 101 and the guide bars 102. The connecting piece 103 divides the water tank formed between the guide bars 102 and the pressing ribs 101 into two water tanks, and the water tank close to the guide bars 102 is communicated with the sewage tank 52. After the pressing ribs 101 extrude the cleaning roller 4, excessive water on the cleaning roller 4 flows into the water tank formed between the connecting piece 103 and the guide bars 102 through the connecting piece 103, and then flows into the sewage tank 52.

[0104] In some embodiments, as shown in Figure 3 , Figure 4As shown, the distance between the end of the pressing rib 101 close to the cleaning roller 4 and the end of the pressing rib 101 close to the cleaning head housing body 10 is greater than the distance between the end of the guide bar 102 close to the cleaning roller 4 and the end of the guide bar 102 close to the cleaning head housing body 10. In other words, the pressing rib 101 presses the wiping layer 41 more deeply, while the guide bar 102 presses the wiping layer 41 more shallowly. This design makes it easier for the pressing rib 101 to scrape and press the wiping layer 41 to guide the sewage out, while the guide bar 102 is more easily in elastic abutment with the wiping layer 41 to guide the pressed-out sewage to the sewage outlet 111.

[0105] In one or some optional embodiments, as shown in the drawings, the cleaning head housing body 10 is provided with a water tank 110, and the water tank 110 is provided with a sewage outlet 111. Figures 3 to 8 As shown, the cleaning head housing body 10 is provided with an opening (not labeled in the drawings) at the top of the area opposite the water tank, and the cleaning head assembly further comprises a sealing cover, i.e., the air-permeable cover 2, which covers the opening at the top of the cleaning head housing body 10. The air-permeable cover 2 comprises an air-permeable cover body 21 and a sealing eave 22, and the air-permeable cover body 21 is further provided with an air-permeable cavity 23. The sealing eave 22 at the periphery of the air-permeable cover body 21 is just sealed and covers the opening at the top of the cleaning head housing body 10. 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, the air-permeable cover body 21 of the air-permeable cover 2 is provided with the sealing eave 22, which is just sealed and covers the opening at the top of the cleaning head housing body 10. The air-permeable cover 2 can inhibit the liquid water from overflowing outward and allow air to permeate. When the user uses the scrubber for a period of time and needs to further clean the water tank, the user can remove the air-permeable cover 2 to flush the inside of the water tank. The air-permeable cavity 23 is transparent, so that the user can directly see the flow of clean water and sewage in the water tank through the air-permeable cavity 23 without having to remove the air-permeable cover 2 in sequence.

[0106] In some embodiments, the locking mechanism of the cleaning roller protective cover 13 comprises a pair of elastic locking pieces (not labeled in the drawings) arranged on both sides of the cleaning roller protective cover 13, and the elastic locking pieces are provided with first clamping locking tongues (not labeled in the drawings). The two end walls (the first end wall 11 and the second end wall 12) of the cleaning head housing 1 are provided with a pair of first clamping holes (not labeled in the drawings) corresponding to the elastic locking pieces.

[0107] In the embodiment, the two elastic locking pieces on the two sides of the cleaning roller cover 13 elastically abut against the two end walls (the first end wall 11 and the second end wall 12) of the cleaning head shell 1. The elastic locking pieces can be elastic pieces made of other materials and commonly understood by those skilled in the art to be clamped on the two sides of the two end walls. The elastic locking pieces can also be hooks that are integrally formed with the cleaning roller cover 13 and can be elastically deformed. The elastic locking pieces are provided with first clamping locking tongues. The two end walls of the cleaning head shell 1 are provided with a pair of first clamping holes corresponding to the elastic locking pieces. The specific forms of the first clamping locking tongues and the first clamping holes are not limited in the application, as long as the two can be smoothly and stably clamped. The elastic locking pieces on the two sides of the cleaning roller cover 13 can facilitate the user to easily align the closing position of the cleaning roller cover 13 on the cleaning head shell 1, and after closing in place, the user can hear a crisp clamping sound or feel a slight clamping vibration, thereby reminding the user that the closing action of the cleaning roller cover 13 has been completed.

[0108] In some embodiments, the locking mechanism further includes an elastic locking rod assembly (not shown in the drawings) provided inside the top wall of the cleaning roller cover 13 and capable of simultaneously extending and retracting to the two sides of the two end walls of the cleaning head shell 1. The two end portions of the elastic locking rod assembly are each provided with a second clamping locking tongue (not shown in the drawings). The two end walls of the cleaning head shell 1 are provided with a pair of second clamping holes (not shown in the drawings) corresponding to the second clamping locking tongues.

[0109] In the embodiment, the top wall of the cleaning roller cover 13 is provided with an elastic locking rod assembly (not shown in the drawings) capable of simultaneously extending and retracting to the two sides of the two end walls of the cleaning head shell 1. The two end portions of the elastic locking rod assembly are each provided with a second clamping locking tongue. The extension or retraction of the two locking tongues can be controlled by two elastic buttons provided in the concave portion at the top of the cleaning roller cover 13. The two end walls of the cleaning head shell 1 are provided with a pair of second clamping holes corresponding to the locking tongues. When the user needs to close the cleaning roller cover 13 on the cleaning head shell 1, in addition to the automatic locking of the elastic locking pieces described above, another step requires the user to continue to press the cleaning roller cover 13 downward until the two locking tongues of the elastic locking rod assembly are automatically ejected and locked in the second clamping holes of the two end walls under the elastic action, thereby reliably completing the closing action of the cleaning roller cover 13. As Figure 6As 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 can bear impact force in various directions after being clamped in place, which is much greater than the first clamping locking tongue. The reliable and stable clamping force for clamping the cleaning roller cover 13 to the cleaning head shell 1 mainly comes from the second clamping locking tongue of the elastic locking rod assembly. When the user needs to remove the cleaning roller cover 13, the user first needs to press the two elastic buttons in the lower concave portion at the top of the cleaning roller cover 13 to control the retraction of the two locking tongues, and then can simply lift the entire cleaning roller cover 13 upward.

[0110] In one or some optional embodiments, as Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 As shown, the cleaning head shell 10 further includes a handle mounting portion 104, and a handle (not shown in the drawings) of the scrubber can be rotatably connected to the handle mounting portion 104.

[0111] In a second aspect, as Figures 1 to 2 shown, the present application further provides a cleaning head assembly, which includes the cleaning head shell 1 with the open cleaning tank of the first aspect, the cleaning roller 4, and the 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 water flow channels connected to the open cleaning tank. The cleaning roller 4 is clamped between the two end walls of the cleaning head shell 1, and the cleaning roller 4 includes a driving motor 4a mounted on one end wall and a cleaning drum (not shown in the drawings) sleeved on the output end of the driving motor. The cleaning drum is sleeved with a wiping layer 41 on the outer surface. The water tank assembly 5 can be installed, taken out, and placed from one end wall of the cleaning head shell 1, and the water tank assembly 5 includes a clean water tank 51 and a sewage tank 52 connected to the open cleaning tank. The cleaning head assembly further includes a pair of rear wheels 8 mounted on the cleaning head shell 10, a pair of auxiliary wheels (not shown in the drawings) mounted on the bottom of the cleaning head shell 10, and the cleaning roller 4 together bear the weight of the entire cleaning head assembly. Under the driving force of the driving motor 4a sleeved in the cleaning roller 4, the scrubber can freely mop the floor by cooperating with the user's own pushing and pulling.

[0112] 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 synchronously driving the brush assembly 3 to rotate. The brush assembly 3 is used to sweep the solid garbage and sticky garbage lifted by the cleaning roller 4.

[0113] In a third aspect, the application further provides a floor cleaning machine, which comprises the above-mentioned cleaning head assembly and a handle. The floor cleaning machine can be moved by pushing the handle to clean the area to be cleaned.

[0114] Specifically, the specific working mode of the floor cleaning machine provided by the application is as follows: the floor cleaning machine 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 transported to the surface of the cleaning roller 4 through the clean water tank 51 of the water tank assembly 5 and the clean water pipeline (not marked in the drawing) to wet the surface of the cleaning roller 4. At the same time, 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 collection 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. Through the gap between the shovel strip assembly 6 and the wiping layer 41 of the cleaning roller 4 and the friction force of the wiping layer 41 of the cleaning roller 4, the garbage is brought into the garbage collection assembly 7. At the same time, 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 collection assembly 7, thereby realizing the collection of the garbage on the ground. In addition, when the floor cleaning machine works, clean water is continuously transported 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 through the connecting piece 103. The sewage is transported to the sewage tank 52 of the water tank assembly 5 through the water tank.

[0115] 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 should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.

Claims

1. An open-type water tank, disposed inside the cleaning head housing of a floor scrubber and mounted on a cleaning roller, characterized in that, include: The pressure ribs and guide strips are both located on the inner side of the top wall of the cleaning head housing, protruding towards and abutting against the cleaning roller. The pressure ribs scrape away dirt and sewage on the cleaning roller, and the guide strips guide the sewage away. The guide strips are integrally formed with the cleaning head housing, or can be detachably connected to the cleaning head housing. The connector, which connects the pressure rib and the guide bar, has filter holes evenly distributed on the lower surface of the cleaning roller. The cross-section of the connector gradually decreases in distance from the surface of the cleaning roller from the guide bar towards the pressure rib. The cross-section of the connector is Z-shaped, with a gap between the upper surface of the upper end of the Z-shape and the top wall of the cleaning head housing, and a gap between the lower surface of the lower end of the Z-shape and the cleaning roller. The lower end of the Z-shape of the connector's cross-section forms an arc shape with a gradually decreasing distance from the surface of the cleaning roller towards the pressure rib. A gap is left between the vertical section of the Z-shape of the connector's cross-section and the vertical surface of the guide bar, which can accommodate large particles of waste. Multiple strip-shaped open slots are spaced apart on the upper surface of the upper end of the Z-shape of the connector's cross-section, extending upwards from the upper surface of the cleaning roller located between the pressure rib and the guide bar along the four walls of the multiple open slots to the inner wall of the vent cover, creating multiple open spaces that can accommodate and limit large particles of waste. A vent cover is placed over the strip opening on the top wall of the cleaning head housing, directly opposite the connector, to prevent liquid water from overflowing and to allow air to pass through. The open water tank is formed by the pressure ribs, guide strips, and the upper surface of the cleaning roller located between the pressure ribs and guide strips. The two ends of the open water tank are connected to the clean water tank and wastewater tank of the floor scrubber through the end walls of the two cleaning head housings, respectively.

2. The open-type water tank as described in claim 1, characterized in that, The upper Z-shaped end of the connector near the guide bar and the vertical Z-shaped section gradually tighten towards the guide bar from at least one of the two end walls until its cross-section changes from a Z-shape to an L-shape.

3. The open-type water tank as described in claim 1, characterized in that, The ribs are integrally formed with the cleaning head housing, or are detachably connected to the cleaning head housing.

4. A cleaning head assembly, characterized in that, include: The cleaning head housing has an open water tank and two end walls for holding the cleaning roller as described in any one of claims 1-3, and each end wall is provided with a water flow channel connecting to the open water tank. The cleaning roller is clamped between the two end walls of the cleaning head housing, including a drive motor mounted on one end wall and a cleaning roller sleeved on the output end of the drive motor. The water tank assembly, which can be installed and removed from one end wall of the cleaning head housing, includes a clean water tank and a wastewater tank that connect to an open water tank.

5. A floor scrubbing machine, characterized in that, Includes the cleaning head assembly as described in claim 4.
