The following will describe the aspects of the present utility model in detail with reference to the accompanying drawings.

In the prior art, as shown in fig. 1 to 3, a wringing strip 3 is mounted on a housing 10 of a cleaning head 1 for washing the floor, the wringing strip 3 extrudes the surface of a cleaning roller 2, the wringing strip 3 is mounted on a cleaning roller guard plate (not shown in the drawing) with one vertical end face inside the housing 10, a vertical plate (not shown in the drawing) is arranged on the opposite side of the guard plate, a water supporting strip 4 is mounted on the vertical plate, a part of the surface of the wringing strip 3, a part of the surface of the cleaning roller 2, a part of the surface of the water supporting strip, a part of the surface of the vertical plate and a part of the surface of the cleaning roller guard plate enclose a washing tank (not shown in the drawing) which can make clear water continuously wash the upper surface of the cleaning roller, and a detachable flip cover 11 is further arranged right above the washing tank. The wringing strip 3 includes a wringing portion 31, an extension portion 32, and a water dividing hook 33. The wringing portion 31 extends toward the axial direction of the cleaning roller 2, scrapes and squeezes the surface of the cleaning roller 2 to scrape off liquid and solid particle garbage adhering to the surface of the cleaning roller 2, and sewage on the surface of the cleaning roller 2 after washing with clear water is mixed with fine particle garbage and is squeezed out by the wringing strip 3. The extension portion 32 extends from the wringer portion 31 in a tangential direction of the surface of the cleaning roller 2, and gradually precompresss the surface of the cleaning roller 2 from a free state to a state to be squeezed along the rotation direction of the cleaning roller 2. The gap between the lower surface of the extension 32 and the upper surface of the cleaning roller 2 provides a forward flow path for the sewage scraped by the wringer portion 31 and mixed with fine particulate waste, which path is referred to as stratosphere zone a for ease of discussion. The water dividing hook 33 extends from the extension 32 in a direction away from the cleaning roller. The extension 32 is uniformly provided with filtering through holes 321 penetrating the upper and lower surfaces thereof. Although the extension portion 32 is uniformly provided with the filtering through holes 321 penetrating through the upper and lower surfaces thereof, as the gap between the lower surface of the extension portion 32 and the upper surface of the cleaning roller 2 is larger, more clean water is not really deeply washed on the upper surface of the cleaning roller 2, and the clean water flows along the stratosphere area a of the upper surface of the cleaning roller 2 to the collecting area E of the cleaning tank together with the sewage scraped by the water extruding portion 31, and is pumped away by the sewage pipeline, so that the cleaning efficiency of the clean water needs to be improved. The sewage can only be pumped away by the sewage line (not shown) after reaching the collecting area E. When solid garbage, liquid garbage or mixed garbage is present on the surface to be cleaned, the cleaning roller 2 firstly lifts the solid garbage, the liquid garbage or the mixed garbage into the garbage guiding channel (not shown in the drawing) through the shovel bar 5, then the brush roller 6 further sweeps the solid garbage passing through the garbage guiding channel into the garbage box (not shown in the drawing), some viscous garbage, liquid garbage and fine particle garbage are difficult to sweep by the brush roller 6 and can further pass through the tip part (not shown in the drawing) of the water supporting bar 4 and the water squeezing part 31 of the water squeezing bar 3 in sequence, and the water squeezing part can scrape and squeeze the viscous garbage, the liquid garbage and the mixed garbage mixed with the fine particle garbage together to separate the upper surface of the cleaning roller 2, and further the solid garbage is flushed by clean water in the cleaning tank, so that the ground to be cleaned is realized.

In a first aspect, as shown in fig. 4-14, the present utility model provides a multiple filtering wringer bar, which is installed on a housing 10 of a cleaning head 1 of a floor washing machine, wherein the wringer bar 3 presses a surface of a cleaning roller 2, and the wringer bar 3 includes a wringer portion 31, an extension portion 32 and a water diversion hook 33. The wringing portion 31 extends toward the axial direction of the cleaning roller 2, scrapes and squeezes the surface of the cleaning roller 2 to scrape off liquid and solid particle garbage adhering to the surface of the cleaning roller 2, and sewage on the surface of the cleaning roller 2 after washing with clear water is mixed with fine particle garbage and is squeezed out by the wringing strip 3. The extension portion 32 extends from the wringer portion 31 in a tangential direction of the surface of the cleaning roller 2, and gradually precompresss the surface of the cleaning roller 2 from a free state to a state to be squeezed along the rotation direction of the cleaning roller 2. A tiny elastic gap is reserved between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2 and between the lower surface of the extension part 32 and the upper surface of the water supporting strip 4, the extension part 32 is uniformly distributed with filter through holes 321 penetrating through the upper surface and the lower surface of the extension part, and the diameter of the filter through holes 321 is larger than the minimum gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2. The water diversion hook 33 extends from the extension portion 32 towards the direction deviating from the cleaning roller, and divides the cleaning tank into a plurality of water flow filtering areas, as the filtering through holes 321 are uniformly distributed on the extension portion 32, the sewage on the surface of the cleaning roller 2 extruded by the water extrusion portion 31 is mixed with fine particle garbage and arrives at different areas of the cleaning tank in two ways, one sewage is mixed with larger particle garbage and arrives at the first filtering area B through the filtering through holes 321, the other sewage is mixed with smaller particle garbage and arrives at the collecting area E through the stratosphere area A, and the sewage flows through elastic gaps between the lower surface of the extension portion 32 and the upper surface of the cleaning roller 2, between the lower surface of the extension portion 32 and the upper surface of the water supporting strip 4. The water diversion hooks 33 are uniformly provided with filtering through holes 331 penetrating the front surface and the rear surface thereof, and the diameter of the filtering through holes 331 is smaller than that of the filtering through holes 321 of the extension parts 32. When the sewage passes through the first filtering area B, the sewage can further pass through the filtering through holes 331 to further filter the finer particle garbage, and the sewage that further passes through the filtering through holes 331 can further flow into the collecting area E. When the sewage flow rate of the first filtering area B is large, and the filtering of finer particle garbage is not continued, the sewage can turn over the top of the water diversion hook 33 and then fall to the collecting area E. The wringing strip 3 can be provided with more than one water diversion hook. When the wringer strip 3 has only one water dividing hook, the water dividing hook 33 has only a vertical section (not shown in the drawing), and the water dividing hook 33 extends only in a direction away from the cleaning roller 2. When the wringing strip 3 has only two water-dividing hooks, the first water-dividing hook 33a has only a vertical section (not shown in the drawing), and the first water-dividing hook 33a extends only in a direction away from the cleaning roller 2; the second water diversion hook 33b comprises an extension section and a vertical section, wherein the extension section extends from the root of the first water diversion hook 33a along the tangential direction of the surface of the cleaning roller 2, and the vertical section extends from the tail end of the extension section towards the direction away from the cleaning roller. When the wringing strip 3 has more than two water diversion hooks, the water diversion hooks comprise a main water diversion hook and a secondary water diversion hook, the main water diversion hook extends from the tail end of the extension part 32 only towards the direction deviating from the cleaning roller, each secondary water diversion hook comprises an extension section and a vertical section, the extension section of the secondary water diversion hook extends from the root of the previous water diversion hook along the tangential direction of the surface of the cleaning roller 2, and the vertical section of the secondary water diversion hook extends from the tail end of the extension section of the secondary water diversion hook towards the direction deviating from the cleaning roller.

In the application, the multiple filtering wringing strip 3 is matched with the elastic gaps between the bottom of the extension part 32 and the upper surfaces of the cleaning roller 2 and the water supporting strip 4, so that the clean water and the sewage extruded by the wringing strip can reach the collecting area only through at least one water flow filtering area, and the utilization rate of the clean water is improved. On the other hand, the washing tank of the floor washing machine is physically partitioned by the multiple filtering wringing strips 3 through the water diversion hooks 33, and the detachable flip cover of the washing tank of the floor washing machine is matched, so that a user can more accurately and regularly clean a filtering area possibly having a blocking risk without thoroughly and comprehensively cleaning the whole washing tank once every time, and the maintenance and cleaning efficiency of the washing tank is improved.

Fig. 4 shows a schematic view and a schematic view of a flow direction of clear water of a washing tub in which a wringer bar having a single water diversion hook is installed at a cleaning head according to an exemplary embodiment of the present application.

In some embodiments, as shown in fig. 4, the wringer strip 3 is provided with only one water diversion hook 33, and the second filtering through holes 331 are uniformly distributed on the water diversion hook. Compared with the prior art, the embodiment uniformly distributes the second filtering through holes 331 on the water diversion hooks, further narrows the gaps between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2, and between the lower surface of the extension part 32 and the upper surface of the water supporting strip 4, so that the sewage extruded by the clean water and the water squeezing strip can reach the collecting area E only through at least one first filtering area B, and the utilization rate of the clean water is improved.

Of course, the wringing strip 3 may also have more than three water diversion hooks, including a master water diversion hook and a slave water diversion hook. The technical scheme different from the previous embodiment is that: only one of the main water diversion hooks is a main water diversion hook directly extending from the extension part 32, and the rest water diversion hooks are all secondary water diversion hooks. The main water diversion hooks extend from the tail end of the extension part 32 only towards the direction away from the cleaning roller, each of the main water diversion hooks comprises an extension section and a vertical section, the extension section extends from the root of the last water diversion hook along the tangential direction of the surface of the cleaning roller 2, and the vertical section extends from the tail end of the extension section towards the direction away from the cleaning roller.

Other details of the embodiment of the wringing strip having more than three water diversion hooks are the same as those of the previous embodiment, and will not be described in detail here.

In some embodiments, in order to make the multi-filtering wringing strip more convenient to extrusion and stretch a single section profile as shown in fig. 4-14 by using a metal material in a thermoplastic forming manner, of course, the multi-filtering wringing strip can also be injection molded into a shape required by using a non-metal material in a thermoplastic forming manner, and in order to facilitate further processing of the filtering through holes by other processes such as stamping, machining and the like, the wall thickness from the starting end of the extension portion of the wringing strip to the tail end of the water diversion hook of the wringing strip is gradually narrowed.

In some embodiments, in order to make the multi-filtering wringing strip more convenient to extrude and stretch a single section profile as shown in fig. 4-14 by using a metal material in a thermoplastic forming manner, of course, the multi-filtering wringing strip can also be injection molded into a shape required by using a non-metal material in a thermoplastic forming manner, and in order to facilitate further processing of the filtering through holes by other processes such as stamping, machining and the like, the wall thickness from the starting end of the extension portion of the wringing strip to the tail end of the water diversion hook of the wringing strip is constant.

In some embodiments, as shown in fig. 4-14, the multiple filtration wringer strip further comprises a mounting portion (not shown) removably connected to the floor washing machine housing 10, the mounting portion comprising a thin-walled first mounting portion 35 perpendicular to the wringer portion 31, the first mounting portion 35 being removably connected to the housing 10. The mounting portion further includes a second mounting portion 34 extending upward from the wringing portion 31, and the second mounting portion 34 is engaged with a corresponding groove of the housing 10. When the wringing strip is installed, a user only needs to clamp the second installation portion 34 into the corresponding groove of the shell 10, and then the first installation portion 35 is fixedly connected with the shell 10 by using a fastener at the first installation portion 35, so that the installation is completed. When the wringing strip is required to be detached, a user only needs to loosen the fastener at the first mounting portion 35 to release the connection between the first mounting portion 35 and the housing 10, and then pull out the second mounting portion 34 from the corresponding groove of the housing 10, so that the detachment is completed. This allows the mounting portion to receive a torque force from the wringer portion 31 in both the transverse direction (i.e., tangential direction of the cleaning roller 2) and the longitudinal direction (i.e., direction toward the axis of the cleaning roller 2), so that the wringer bar 3 can stably scrape the cleaning roller surface during high-speed rotation of the cleaning roller 2. The process of installing and dismantling the wringing strip is very convenient, and the difficulty of maintaining the cleaning head by a user is reduced. Of course, other structures of the mounting portion may be adopted, so long as the wringing strip can stably bear the transverse and longitudinal torsion forces received by the wringing portion 31, which are all within the scope of the present application.
