As analyzed in the background technology of the present application, the sewage tank of the existing floor washing machine is easy to block and the water tank is easy to stink if it is not used for a long time. In order to solve the above technical problems, for this reason, the first aspect, as shown in Figure 1 to Figure 7 As shown, the embodiment of the present invention provides an open water tank. The open water tank is arranged inside the cleaning head housing 1 of the floor washing machine and erected on the cleaning roller 4. The open water tank includes a bead 101, a guide Strip 102, connecting piece 103, air-permeable cover 2; the bead 101 and the guide bar 102 are arranged on the inside of the top wall of the cleaning head housing 1 and protrude toward the cleaning roller 4 and abut against it; the connecting piece 103 Connect the bead 101 and the guide bar 102, which are evenly distributed with filter through-holes 10311 near the lower surface of the cleaning roller 4; the air-permeable cover 2 is covered on the top wall of the cleaning head housing 1 and faces the connecting piece 103 on the strip-shaped opening (not marked in the accompanying drawings), the air-permeable cover 2 can inhibit liquid water from overflowing and ventilating; The upper surface of the cleaning roller 4 and the two end walls (11, 12) of the cleaning head housing 1 jointly surround the open water tank (not shown in the drawings), and the two ends of the open water tank are respectively Connect the fresh water tank 51 and the dirty water tank 52 of the washing machine. When cleaning the water tank, the user only needs to remove the vent cover 2 for convenient cleaning. When the user does not use the scrubber for a long time, since the vent cover 2 can ventilate outward, it is not easy to clean the open tank. smell.

The cleaning head housing 1 provided in this embodiment includes a cleaning head housing body 10 , a first end wall 11 , a second end wall 12 and a cleaning roller cover 13 , and the cleaning roller cover 13 is covered on the cleaning head housing body 10 Above, it is used to cover the cleaning roller 4 of the floor washing machine. The cleaning head housing body 10 includes beading 101, guide bar 102 and connecting piece 103. Both beading 101 and guide bar 102 are arranged on the cleaning head housing body 10. Both the bead 101 and the guide bar 102 are in contact with the cleaning roller 4 installed in the cleaning head housing 1 to form a water tank, the bead 101 is used to squeeze out excess water on the cleaning roller 4, and the guide bar 102 is used to block The sewage extruded on the cleaning roller 4 flows into the garbage collection assembly 7. When the cleaning roller 4 cleans the ground, the bead 101 contacts with the cleaning roller 4 and squeezes the cleaning roller 4. At the same time, the bead 101 and the guide bar The connection piece 103 connected between 102 can filter the particles in the sewage, so as to prevent the sewage from entering the sewage tank, thereby preventing the sewage tank from being blocked. The cleaning roller cover 13 also includes a locking mechanism (not shown in the accompanying drawings) that is located on the cleaning roller cover 13. When the user needs the water tank for maintenance and cleaning, the user only needs to easily release the lock to remove the locking mechanism. The cleaning roller cover 13 is removed from the cleaning head casing 1, and when it needs to be installed back on the cleaning head casing 1, the cleaning head can be adjusted through multiple locking points (not shown in the accompanying drawings). The housing 1 is firmly covered, and the cleaning roller cover 13 is also provided with a long hollow groove (not shown in the drawings), and the vent chamber 23 part of the breathable cover 2 just passes through the hollow groove.

In this embodiment, the connecting piece 103 provided between the bead 101 and the guide bar 102 is mainly used for filtering sewage, preventing particles in the sewage from flowing into the sewage tank in the washing machine, that is to say, the connecting piece 103 can be set Between the bead 101 and the guide bar 102 and before the entrance of the sewage tank, its specific actual location can be selected according to the actual application, which is not specifically limited in this embodiment.

In one or some optional embodiments, the distance from the cross section of the connecting member 103 to the surface of the cleaning roller 4 gradually decreases from the point connecting the guide bar 102 along the direction toward the bead 101 .

In this embodiment, as shown in Fig. 3 and Fig. 4, the cross section of the connector 103 starts from the joint connecting the guide bar 102, and moves away from the surface of the cleaning roller 4 along the direction pointing to the bead 101. The distance gradually decreases until the connecting piece 103 is connected to the bead 101, and the bead 101 elastically abuts against the surface of the cleaning roller. Preferably, the joint where the connecting member 103 connects the bead 101 is higher than the surface of the cleaning roller 4, so as to prevent dirt from accumulating in the gap of the joint during the use of the washing machine. The cross-section of the connector 103 starts from the joint of the connecting guide bar 102 and gradually shrinks away from the surface of the cleaning roller 4 in the direction of the bead 101, so that the wiping layer 41 of the cleaning roller 4 can be rotated along the direction of rotation of the cleaning roller. Seen from above, the wiping layer 41 that has not been squeezed by the bead 101 on the front side of the bead 101 can have a certain buffer space. The layer 41 can transition slowly and smoothly, so as to reduce the current in the working state of the drive motor 4a of the scrubber that drives the cleaning roller 4 to rotate.

In one or some optional embodiments, the distance from the surface of the cleaning roller 4 to the cross section of the connecting member 103 gradually decreases from the middle along the direction to the bead 101, and its cross section starts from the middle along the The distance from the surface of the cleaning roller 4 to the direction of the guide bar 102 is kept constant.

In this embodiment, as shown in Fig. 3 and Fig. 4, the cross section of the connecting piece 103 starts from the middle, and the distance from the surface of the cleaning roller 4 along the direction to the bead 101 gradually decreases until the connecting piece 103 It is connected to the bead 101, and the bead 101 elastically abuts against the surface of the cleaning roller. Preferably, the joint where the connecting member 103 connects the bead 101 is higher than the surface of the cleaning roller 4, so as to prevent dirt from accumulating in the gap of the joint during the use of the washing machine. The cross-section of the connector 103 gradually shrinks from the middle along the direction to the bead 101 from the distance on the surface of the cleaning roller 4, so that the wiping layer 41 of the cleaning roller 4 can be viewed along the direction of rotation of the cleaning roller. The wiping layer 41 on the front side of 101 that has not been squeezed by the bead 101 can have a certain buffer space, so that the wiping layer 41 can be slow and smooth during the change process of the two states from being not squeezed to the maximum degree of being squeezed Transition, in order to reduce the electric current under the working state of the drive motor 4a that drives the cleaning roller 4 of the washing machine to rotate. The reason why it starts from the middle is to make the lower surface of this section of the connecting piece from the connection of the connecting piece 103 connecting the guide bar 102 to the middle of the connecting piece 103 must be higher than the surface of the cleaning roller 4, that is, this section of the connecting piece There is a gap between the lower surface of 103 and the cleaning roller 4 surface, so that the clear water and sewage flowing down from the filter through hole 10311 also have a certain initial velocity to continue to wash the surface of the wiping layer 41 in the gap, which is more conducive to improving the cleaning efficiency.

In one or some optional embodiments, the cross section of the connector 103 is Z-shaped, and there is a gap between the upper surface of the Z-shaped upper end 1033 and the top wall of the cleaning head housing 1, and the Z-shaped There is a gap between the lower surface of the lower end 1031 and the cleaning roller 4 .

In this embodiment, as shown in FIGS. 3 to 8 , the cross-section of the connector 103 is Z-shaped, and a gap is left between the upper surface of the Z-shaped upper end 1033 of the connector 103 and the top wall of the cleaning head housing 1. There is a gap between the lower surface of the zigzag lower end 1031 of the connector 103 and the cleaning roller 4 . As shown in Fig. 3 and Fig. 4, in conjunction with Fig. 5 to Fig. 8, the open water tank has an open top as a whole, and the air-permeable cover 2 covers the top opening of the open water tank. The top wall of the head shell 1 actually refers to the vent cover 2 . There is a gap between the upper surface of the zigzag upper end 1033 of the connector 103 and the breathable cover 2, which can allow the air in the upper space of the tank to circulate more easily, so that it is not easy to stink in the tank at any time. There is a gap between the lower surface of the zigzag lower end 1031 of the connector 103 and the cleaning roller 4, so that the clear water and sewage flowing down from the filter through hole 10311 also have a certain initial velocity to continue to wash the surface of the wiping layer 41 in the gap, more Helps improve cleaning efficiency.

In one or some optional embodiments, the zigzag lower end 1031 of the cross section of the connecting member 103 points to the bead 101 in an arc shape whose distance from the surface of the cleaning roller 4 gradually decreases.

In this embodiment, as shown in Figure 3 and Figure 4, the Z-shaped lower end 1031 of the cross section of the connector 103 points to the bead 101 and is in the shape of an arc whose distance from the surface of the cleaning roller 4 gradually decreases, so that the cleaning roller 4 Viewing the wiping layer 41 along the direction of rotation of the cleaning roller, the wiping layer 41 that has not been extruded by the bead 101 on the front side of the bead 101 can have a certain buffer space. During the change process of the two states to the greatest extent, the wiping layer 41 can be slowly and smoothly transitioned, so as to reduce the current of the driving motor 4a in the working state of the driving cleaning roller 4 of the scrubber.

In one or some optional embodiments, the zigzag upper end 1033 and the zigzag vertical section 1032 of the connecting piece 103 close to the guide bar 102 are close to at least one of the two end walls (11, 12) start to gradually tighten toward the direction of the guide bar 102 until its cross-section changes from a Z-shape to an L-shape.

In some embodiments, as shown in FIG. 5 , the zigzag upper end 1033 and the zigzag vertical section 1032 of the connecting member 103 close to the guide bar 102 gradually tighten toward the guide bar 102 from close to the second end wall 12 until Its cross section changes from Z-shape to L-shape. In conjunction with Fig. 3 and Fig. 4, there is a gap between the front end surface of the Z-shaped vertical section 1032 of the connector and the facade of the guide bar 102. We call this gap space on the facade a large particle garbage storage area J, and the cleaning head The cross-sections of assembly 1 at different positions in the axial direction of the cleaning roller 4 show that the cross-sectional width dimension of the large-particle garbage accommodation area J gradually decreases as it advances toward the direction of the guide bar 102 until the width dimension is reduced to zero. At this time , the cross section of the connector 103 becomes L-shaped. In this way, the clean water outlet 121 on the second end wall 12 and the sewage outlet 111 on the first end wall 11 in the water tank can be staggered in the water outlet direction, so as to prevent the clean water from directly flowing into the sewage outlet along the upper surface of the connecting piece 103 111, which can improve the replacement efficiency of clean water and sewage in the tank, thereby improving the cleaning efficiency of the floor washing machine.

In some embodiments, as shown in FIG. 8 , the zigzag upper end 1033 and the zigzag vertical section 1032 of the connecting member 103 close to the guide bar 102 gradually shrink towards the guide bar 102 from near the two end walls ( 11 , 12 ). Tighten until its cross-section changes from a Z-shape to an L-shape. Combining with Figure 3, Figure 4, and Figure 6, there is a gap between the front end surface of the Z-shaped vertical section 1032 of the connector and the facade of the guide bar 102, and we call this gap space on the facade a large particle garbage storage area J , the cross-sections of the cleaning head assembly 1 at different positions in the axial direction of the cleaning roller 4 show that the cross-sectional width dimension of the large-particle garbage accommodation area J gradually decreases as it advances toward the direction of the guide bar 102, until the width dimension is reduced to zero. , at this time, the cross section of the connector 103 becomes L-shaped. The same technical solutions and technical effects as those in the foregoing embodiments will not be repeated here. The zigzag upper end 1033 and the zigzag vertical section 1032 of the connecting member 103 close to the guide bar 102 gradually move toward the guide bar from near the first end wall 11. The direction of 102 is tightened until its cross section changes from Z-shaped to L-shaped, which can widen the width of the sewage outlet 111 in the width direction of the water tank and allow the sewage to flow more smoothly, thereby further reducing the power of the water pump of the washing machine and further reducing the washing machine. The power consumption and noise of the whole machine.

In one or some optional embodiments, the bead 101 is integrally formed with the housing body 10 of the cleaning head, or is detachably connected with the housing body 10 of the cleaning head.

In this embodiment, as shown in FIGS. 2 to 8 , during the manufacturing process, the cleaning head housing body 10 can be molded to form several protrusions on its surface, and the protrusions can be directly used as extrusion The bead 101 of the cleaning roller 4, the structure of the end of the bead 101 elastically abutting against the cleaning roller 4 matches the cleaning roller 4, that is to say, the end of the bead 101 abutting against the cleaning roller 4 can be an arc-shaped end. Of course, the end of the bead 101 abutting against the roller cleaning roller 4 may be a non-arc end, such as a zigzag end, a polygonal end, etc., which is not specifically limited in this embodiment. Preferably, the bead 101 has a single linear cross-sectional shape and is kept parallel to the axis of the cleaning roller 4 . Further, the bead 101 can be tightened toward the inside of the water tank near the two end walls (not shown in the drawings), so as to prevent the cleaning roller 4 from moving toward the axial direction of the cleaning roller 4 in the entire cleaning head assembly. When one side is inclined, the entire cleaning head assembly is prevented from leaking due to excessive water pressure at the elastic contact between the water tank and the end wall at the inclined position. This "tightening" has two meanings. The first meaning is that the bead 101 tightens toward the width direction of the water tank in the direction of narrowing the width of the water tank. The first meaning is that the bead 101 tightens toward the cleaning roller 4. Extending in the axial direction increases the interference fit of the elastic abutment. This double meaning of "tightening toward the inside of the sink" can further improve the water leakage resistance of the entire sink when it is used at any angle.

In this embodiment, during the manufacturing process of the cleaning head housing body 10, an interface for installing the bead 101 can be reserved on its surface through mold molding, and the bead can be realized by using the installation interface with relevant fasteners if necessary. 101 is detachably connected to the cleaning head housing body 10, and the structure of the end of the bead 101 elastically abutting against the cleaning roller 4 matches the cleaning roller 4, that is to say, the end of the bead 101 abutting against the cleaning roller 4 can be be curved end or non-curved end. After being used for a period of time, the bead 101 is elastically contacted with the wiping layer 41 of the cleaning roller 4 during the working process, the bead 101 and the wiping layer 41 will be worn to a certain extent, and the wear to a certain extent will seriously affect the entire cleaning process. The cleaning efficiency of the floor machine. The cleaning roller 4 itself is positioned as a consumable material, which should be replaced after a period of use. But bead 101 will be much higher than wiping layer 41 because of its own hardness, usually the degree of wear is very small, and there will be a small amount of wear over time. The bead 101 should be replaced when the initial cleaning efficiency of the floor machine is reached. At this time, the bead 101 should be replaced in time. Of course, the material for manufacturing the bead 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 bead 101, such as aluminum alloy, magnesium alloy, magnesium aluminum alloy, zinc alloy, stainless steel, etc. As for the interface form used when the bead 101 is installed on the cleaning head housing body 10 , those skilled in the art can use commonly used ones such as plane step structure, interface structure with grooves or convex grooves, etc., which are not specifically limited in this embodiment.

In one or some optional embodiments, the guide bar 102 is integrally formed with the cleaning head housing body 10 , or is detachably connected with the cleaning head housing body 10 .

In this embodiment, the cleaning head housing body 10 can be molded to form several protrusions on its surface during the manufacturing process. The discharged sewage flows into the guide bar 102 of the garbage collection assembly 7, and the structure of the end of the guide bar 102 elastically abutting against the cleaning roller 4 can also match the cleaning roller 4, that is to say, the guide bar 102 abuts against the cleaning roller 4 One end can be an arc end. Preferably, in order to increase the ability of the guide bar 102 to prevent the cleaning roller 4 from throwing out liquid during high-speed rotation, the end of the guide bar 102 elastically abutting against the wiping layer 41 can be set so that both ends abut against the wiping layer 41, and the middle part is outward. Arch away from the crescent-shaped end of the wiping layer 41 (not shown in the drawings), and the crescent-shaped end has two pointed parts (not shown in the drawings) that elastically contact the wiping layer 41 . Of course, in order to further reduce the resistance of the cleaning roller 4 during high-speed rotation, the tooth-shaped end of the guide strip 102 elastically abutting against the wiping layer 41 may also be only the tip of one end near the bead 101 elastically abutting against the wiping layer 41 . The tip of the other end can facilitate the brush assembly 3 in the cleaning head assembly to directional throw out the brushed solid garbage and sticky garbage to the garbage collection assembly 7 during high-speed rotation, so as to prevent the brush assembly from collecting the garbage again after one revolution. Spin back again and wipe layer 41 surface again. Of course, the end of the guide bar 102 elastically abutting against the wiping layer 41 can also be designed in any shape that can realize the above functions, such as a sickle shape or a wedge shape, which is not specifically limited in this embodiment.

In this embodiment, as shown in Fig. 3 to Fig. 4 and Fig. 6, during the manufacturing process of the cleaning head housing body 10, an interface for installing the guide bar 102 can be reserved on its surface through mold molding. If necessary, the installation interface cooperates with relevant fasteners to realize the detachable connection between the guide bar 102 and the cleaning head housing body 10, and the guide bar 102 can also be directly used to block the sewage squeezed out from the wiping layer 41 of the cleaning roller 4 from flowing into the garbage collection Parts of the assembly 7, the specific structure of the end of the guide bar 102 elastically abutting against the cleaning roller 4 may be consistent with that described in the foregoing embodiments, and will not be repeated here. As shown in FIG. 6 , the cleaning head housing body 10 is provided with a snap groove K for snapping the guide bar 102 on the inner side towards the cleaning roller 4 and between the bead 101 and the brush assembly 3 , as shown in Fig. 3 to As shown in FIG. 4 , the other end of the guide bar 102 away from the cleaning roller 4 is provided with a clamping end (not shown in the drawings), and the clamping end is elastically clamped with the clamping groove. Preferably, an elastic barb structure (not shown in the drawings) is provided on the two side walls of the elastic engagement between the clamping end and the clamping groove, and the elastic barb structure is convenient for the user to easily replace the guide bar 102 The clamping end is clamped into the clamping groove. Preferably, the guide bar 102 has a single linear cross-sectional shape and is kept parallel to the axis of the cleaning roller 4 . Further, the guide bar 102 can be tightened towards the inside of the water tank near the two end walls, so as to prevent the cleaning roller 4 from causing the entire cleaning head assembly to tilt toward the axial side of the cleaning roller 4. In the cleaning head assembly, water leakage occurs due to excessive water pressure at the elastic abutment between the water tank and the end wall at the inclination. This "tightening" has two meanings, which are the same as the meaning of "tightening both ends" of the bead 101 discussed in the foregoing embodiments, and will not be repeated here.

In one or some optional embodiments, one end of the connecting member 103 is connected to the bead 101 .

In this embodiment, the connecting member 103 is detachably connected at the end of the bead 101 abutting against the cleaning roller 4 and toward the side of the guide bar 102 . The lower surface of the connecting piece 103 extends against the guide bar 102 against the surface of the drum assembly. The connecting piece 103 can filter the large particles of garbage brought into the water tank by the cleaning roller 4 and the undissolved granular garbage in the sewage. It is inevitable that a certain degree of stickiness will be generated on the upper surface and the lower surface of the connecting piece 103 during the accumulated use. Garbage deposits, the detachable connector 103 is designed to allow users to remove the connector 103 for thorough cleaning at regular intervals when the simple flushing mode of large water can no longer clean the connector 103 thoroughly, so as to maintain the user's home environment Health and hygiene.

In one or some optional embodiments, the connecting piece 103 extends from the bead 101 toward the side of the guide bar 102 toward the guide bar 102, and the lower surface of the connecting piece 103 is in contact with the A gap is left on the surface of the cleaning roller 4 , and the connecting piece 103 is detachably connected to the bead 101 .

In this embodiment, the connecting member 103 is detachably connected at the end of the bead 101 abutting against the cleaning roller 4 and toward the side of the guide bar 102 . There is a gap 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 to the guide bar 102 . There is a gap (not shown in the accompanying drawings) between the lower surface of the connector 103 and the upper surface of the wiping layer 41 to form a gap space, which can allow the sewage squeezed out by the bead 101 in the gap space to further wash the wiping layer 41 opportunities on the upper surface, and will not allow the lower surface of the connecting piece 103 to also have fine particles of garbage deposited. On the other hand, the gap space can allow the air in the space to circulate, even when the scrubber is not working Sometimes the garbage deposited in the space will not stink due to long-term airtightness. The connecting member 103 has the functions described in the foregoing embodiments, which will not be repeated here.

Further, in this embodiment, the extension end of the connecting piece 103 (not shown in the drawings) is provided with a connecting piece extension hook (not shown in the drawings) extending away from the normal direction of the surface of the drum assembly. , There is a gap between the frontmost surface of the hook portion and the vertical surface of the guide bar 102 (not shown in the drawings).

In this embodiment, the hook portion of the connector 103 deviates from the normal direction along the surface of the drum assembly to form an extension hook portion of the connector (not shown in the drawings). When the ground is on the ground, when the water sucked up by the cleaning roller 4 is squeezed out by the bead 101, when the flow of sewage generated in the water tank is too large, the extended hook of the connector can prevent the sewage from overflowing along the normal direction of the surface of the drum assembly. The top of the hook portion is extended away from the extended connecting piece, so that the squeezed sewage can be forced to pass through the filter of the connecting piece 103 before it can be guided to the sewage outlet 111 at one end of the tank before it can be further transported to the sewage tank 52, thereby preventing The sewage channel caused by sewage bypassing the connection piece 103 is blocked. As shown in FIGS. 3 to 8 , the extended hook portion of the connector continues to extend in a direction parallel to the upper surface of the wiping layer 41 until it forms a connection with the guide bar 102 . The part we call the connector extension connection part (not shown in the accompanying drawings), the connector extension connection part reliably connects the connector extension hook part and the guide bar 102, of course, not all connector extension hook parts and guide bars The parts opposite to the bar 102 need to be reliably connected, and the extended connecting part of the connecting part can be connected at intervals along the axial direction of the cleaning roller 4 to the parts opposite to the extending hook part of the connecting part and the guide bar 102. Partially forms the open channel 10331 of the water tank. As shown in Figures 3 and 4, there is a gap between the front end surface of the extension hook of the connector and the facade of the guide bar 102. We call this gap space on the facade a large particle garbage storage area J, so that the cleaning roller 4 A small amount of large-particle garbage brought up and not brushed off by the brush is hoisted into the sink, and this gap space can often accommodate these large-particle garbage to be constantly flipped and "stayed" here. When the lower surface of the connecting piece 103 When the gap with the wiping layer 41 is smaller than the diameter of the large particles of garbage, these large particles of garbage are turned over and brought to the open slot 10331 that gradually increases the volume of the gap space, and are freely "restricted" in the space within, so as not to be stuck in the narrow gap between the lower surface of the connector 103 and the wiping layer 41 for a long time; Particle garbage is easy to scratch the surface of the wiping layer 41 , thereby shortening the service life of the cleaning roller 4 .

In one or some optional embodiments, as shown in FIGS. 2 to 8 , the connecting member 103 is integrally formed with the cleaning head housing body 10 .

Similarly, the protrusion formed on the cleaning head housing body 10 during the manufacturing process can also be used as a connecting piece 103 for filtering particulate waste in the sewage. After the cleaning roller 4 is installed in the cleaning head housing 1, the protrusion The protrusion also abuts against the cleaning roller 4. At the same time, the protrusion is provided with several filter through holes 10311, the sewage in the tank can be further filtered by the filter through holes 10311, and the filtered sewage can pass through the sewage outlet of the tank 111 is further transported to the sewage tank 52, thereby preventing the sewage channel from being blocked.

It should be noted that the filter through hole 10311 on the connector 103 can be formed during the molding process of the cleaning head housing body 10, or can be set by machining after the cleaning head housing body 10 is formed, which can be adjusted according to actual applications. selection, which is not specifically limited in this embodiment.

It should also be noted that the bead 101, the guide bar 102 and the connecting piece 103 can be simultaneously molded in a single injection during the molding process of the cleaning head housing body 10, and of course can also be molded sequentially by multiple injection molding, that is to say The bead 101, the guide bar 102, the connecting piece 103 and the cleaning head housing body 10 can be integrally formed.

In one or some optional embodiments, one end of the connecting member 103 is disposed on the cleaning head housing body 10 , and the other end abuts against the cleaning roller 4 .

In this 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 prevent the sewage that is thrown out directionally during the high-speed rotation of the cleaning roller 4 and the sewage squeezed out through the bead 101. It will splash in the tank, so that the sewage can slowly flow out of the sewage through the filter through hole 10311 in the connecting piece 103 and the lower surface of the connecting piece 103, and the flowing sewage is further guided to the sewage outlet 111 of the tank through the guide bar 102, and the sewage is further passed through the sewage The channel drains to waste water tank 52 .

In one or some optional embodiments, several filter through holes 10311 are uniformly distributed on the connecting member 103 to isolate solid waste whose particle size is larger than the diameter of the filter through holes.

In this embodiment, as shown in Figures 3 to 8, the diameter of the filter through hole 10311 of the connector 103 can be selected according to different usage scenarios. When the disassembled connection is on the bead 101, the user can configure different connecting parts 103 according to different scenarios according to his actual habits and scenarios of using the scrubber. If the user wants to use the floor washing machine to mop and sweep the house cleaner, he can choose the connecting piece 103 with a smaller filter hole diameter, but the deep cleaning of the connecting piece 103 also needs to be more frequent. Conversely, although the cleaning ability of the floor scrubber may be weaker, the frequency of regular cleaning of the connecting member 103 will be lower.

Further, in some embodiments, as shown in FIG. 3 , FIG. 5 , FIG. 6 and FIG. 7 , the cleaning head housing further includes a first end wall 11 for clamping the cleaning roller 4 , a second The end wall 12, wherein a clean water outlet 121 is provided in the area of the water tank on the second end wall 12, and a sewage outlet 111 is provided in the area of the water tank on the first end wall 11.

In this embodiment, as shown in Figure 3, a clear water outlet 121 is set on the second end wall 12 at one end of the water tank, and as shown in Figure 6, a sewage outlet 111 is set on the first end wall 11 at the other end of the water tank, so as to facilitate The clean water delivered from the clean water tank 51 flows along the water tank, and the clean water can infiltrate into the surface of the wiping layer 41 of the cleaning roller 4 through the connecting piece 103, and the surface of the wiping layer 41 is further scraped and squeezed by the bead 101 so as to realize flushing out with clean water The fine particle garbage mixed in the wiping layer 41 is then replaced with sewage, and then the sewage is further guided to the sewage outlet 111 along the upper surface of the water tank and the guide bar 102, and the sewage is finally discharged to the sewage tank 52 through the sewage channel.

Furthermore, in some embodiments, as shown in FIG. 3 , FIG. 5 to FIG. 7 , the clean water outlet 121 is not directly facing the sewage outlet 111 in the water outlet direction.

In this embodiment, as shown in FIG. 3 , a clean water outlet 121 is provided on the second end wall 12 at one end of the water tank, and the clean water outlet 121 is arranged at a position higher than the upper surface of the connecting piece 103 to facilitate transportation from the clean water tank 51 The clean water that comes flows along the upper surface of the connector 103. Further, the clean water outlet 121 can be set in a circular shape, which is convenient for selecting a circular pipe joint to connect the clean water channel pipeline. Of course, the clean water outlet 121 can be set in a rectangular shape. Select the appropriate pipe joint to facilitate the connection of the clean water channel pipeline. As shown in Figure 6 and Figure 7, a sewage outlet 111 is provided on the first end wall 11 at the other end of the water tank, and the sewage outlet 112 is arranged at a position higher than the upper surface of the connecting piece 103, and the sewage outlet 111 covers the entire water tank This can reduce the resistance of sewage flowing to the sewage channel due to the small diameter of the pipe, and allow the sewage to flow away more smoothly, so that the sewage sent from the surface of the wiping layer 41 can flow along the upper surface of the connecting piece 103 Afterwards, it can be easily and easily discharged into the sewage channel. As shown in Figure 7, combined with Figure 3 and Figure 6, the clean water outlet 121 is not facing the sewage outlet 111 in the water outlet direction, which can prevent the clean water just sent from the clean water outlet 121 from flowing directly along the upper surface of the connector 103 To the sewage outlet 111 , we hope that all the clean water will pass through the connecting piece 103 to replace the clean water and sewage in the wiping layer 41 so as to take away the fine particle garbage mixed in the wiping layer 41 . The scheme in which the clean water outlet 121 is not directly facing the sewage outlet 111 in the water outlet direction will have a higher replacement efficiency for clean water and sewage.

Of course, the clean water outlet 121 and/or the sewage outlet 111 can also be arranged at a position lower than the lower surface of the connecting piece 103. This solution is more direct to the flushing of the surface of the wiping layer 41, but the floor scrubber of this solution After sweeping the ground, it will be more difficult to control the dryness of the ground. Simply put, the ground will be more humid. Users can selectively adjust the positions of the clean water outlet 121 and the sewage outlet 111 at both ends of the sink according to their own usage scenarios.

In some embodiments, as shown in FIGS. The walls jointly form the water tank, and a connecting piece 103 is arranged in the water tank, and the water tank is divided into a wetting area (not shown in the drawings) and a semi-wetting area F by the connecting piece 103, and the wetting area The area is surrounded by the bead 101, the guide bar 102, the upper surface of the cleaning roller 4 between the bead 101 and the guide bar 102, the lower surface of the connector 103 and the walls at both ends. During the working process of the ground machine, no matter whether the water flow in the tank is large or small, the wetting area is always wet, and naturally it is easy to produce the deposition of sticky garbage; the semi-wetting area F is The bead 101, the guide bar 102, the upper surface of the connector 103, the lower surface of the top wall of the cleaning head housing between the bead 101 and the guide bar 102, and the walls at both ends are jointly enclosed. As a result, during the working process of the floor washing machine, the water pump of the floor washing machine intermittently sprays water from the clean water tank 51 to the water tank. , the side wall of the guide strip 102, and most of the top wall of the cleaning head housing are dry. At this time, only the upper surface of the connector 103 has a chance to be wet, and only the upper surface of the connector 103 is more likely to produce stickiness. Garbage deposits. In daily use, if a certain amount of sticky garbage deposits in the wet area and semi-humid area F, it will affect the cleaning efficiency of the scrubber, and the user needs to remove the vent cover 2 to clean the wet area and semi-humid area F in time .

In some embodiments, the connecting piece 103 is arranged at an end of the water tank close to the waste water tank 52 .

In some embodiments, as shown in FIGS. 2 to 8 , the connectors 103 are arranged parallel to the bead 101 and the guide bar 102 respectively, that is to say, the connector 103 is not connected to the bead 101 and the guide bar 102 , but connected The member 103 divides the water tank formed between the guide bar 102 and the bead 101 into two water tanks, and the water tank near the guide bar 102 communicates with the sewage tank 52 . After the bead 101 squeezes the cleaning roller 4 , excess water on the cleaning roller 4 flows into the water tank formed between the connecting piece 103 and the guide bar 102 through the connecting piece 103 , and flows into the sewage tank 52 .

In some embodiments, as shown in FIG. 3 and FIG. 4 , the distance between the end of the bead 101 close to the cleaning roller 4 and the end close to the cleaning head housing body 10 is greater than that of the guide bar 102 The distance between the end close to the cleaning roller 4 and the end close to the cleaning head housing body 10 is simply that the bead 101 presses the wiping layer 41 deeper and the guide bar 102 presses the wiping layer 41 shallower. This design makes it easier for the bead 101 to scrape and squeeze the rolling wiper layer 41 to discharge the sewage, and the guide bar 102 is easier to elastically abut against the wiper layer 41 to guide the squeezed sewage to flow to the sewage outlet 111 .
