The scrubber shown in figure 1 is placed on a base 39 and in use removed from the base 39 and manoeuvred by means of a handle 34, the blower 32 of which is located within the scrubber and is generally not removable, as opposed to a removable arrangement which uses the main cleaner body as the suction source.

The directional arrows in the figure indicate the general flow of the air flow, but the arrows in and below the collecting chamber 11 are primarily intended to indicate the direction of the liquid discharge when the operation is stopped.

The cleaning unit 10 includes a cleaning body and a dirt suction port located in the vicinity thereof, and the dirt suction port communicates with the gas-liquid mixture inflow port of the separation structure via the first flow passage 7.

When the rolling brush 23 of the rolling brush structure is used for cleaning the ground, on one hand, the ground is mopped, on the other hand, the suction source sucks in dirt through the flow channel, if water exists on the ground, the gas-liquid mixture is sucked, or when the rolling brush 23 is in a wet state, the scraping plate presses the periphery of the rolling brush 23, the scraping plate extrudes the dirt while mopping the ground, and the suction source sucks in the gas-liquid mixture.

In order to continuously wet the rolling brush 23, a water injection nozzle is arranged on the circumference of the rolling brush 23 and connected with the clean water barrel 22 through a third flow channel 9.

The third flow channel 9 is a water delivery hose which is provided with a water pump 16 and a water shortage detection sensor 17, and the cleaning part 10 and the suction source can be stopped working in time through signals obtained by the detection of the water shortage detection sensor 17, or information such as water shortage, water adding requirement and water existence is prompted to a user.

The water hose, the water pump 16 and the water shortage detection sensor 17 are mainly arranged in the rear cover 15 of the bracket 14, so that the production and the manufacture are convenient on one hand, and the whole appearance of the floor washing machine is designed on the other hand.

The power for rotating the rolling brush 23 may be electrically driven, or the rolling brush 23 may be rotated in contact with the surface to be cleaned by the pushing force generated when the cleaning part 10 is manually pushed.

The slop pail 1 is equipped with one or more than one separating unit, if there are several separating units, the airflow channels of each separating unit are communicated in sequence, and the slop water separated by each separating unit is discharged into the slop pail 1.

In this example, the design of a slop pail 1 is adopted, and the slop pail 1 is provided with two separation units, so that the separation effect is good, and the size of the structure can be well controlled, and in addition, the design of one slop pail 1 is adopted, so that the slop pail is favorable for dismounting and cleaning, and is convenient for users to use. Of course, more than two separate units are possible, and the slop pail 1 may be more than one.

As shown in fig. 2, two separation units, namely a first separation unit and a second separation unit, are arranged in the slop pail 1, wherein the first separation unit adopts a separation cover structure, and the second separation unit adopts a centrifugal separation structure; the first separation unit comprises a separation cover 2 and a first air inlet pipe 3 which are distributed up and down, the first air inlet pipe 3 is used for inputting a gas-liquid mixture sucked from a dirty suction inlet, and an air outlet end 6 of the first air inlet pipe 3 is a gas-liquid mixture inflow port; in this example, the second separation unit includes a centrifugal separation chamber 4 and a second air inlet pipe 36 which are distributed up and down, an air inlet end 5 of the second air inlet pipe 36 is located above the separation cover 2, an air outlet end 6 of the second air inlet pipe 36 is located in the centrifugal separation chamber 4, of course, other structures are also possible, for example, the second air inlet pipe 36 is omitted, so that the air inlet end 5 is directly located in the centrifugal separation chamber 4, that is, the second separation unit includes the centrifugal separation chamber 4 and the air inlet end 5 located in the centrifugal separation chamber 4, the centrifugal separation chamber 4 is located above the separation cover 2, and at this time, the air inlet end 5 can form good cyclone in the centrifugal separation chamber 4 by arranging a cyclone guide blade. By adopting the combination of the first separation unit and the second separation unit, the separation effect can be further optimized, and the size of the structure can be further controlled.

The first and second separating units are coaxially disposed along the axial direction of the slop pail 1, and in this example, specifically, the second and first separating units are disposed in an up-down arrangement along the axial direction of the slop pail 1, the first separating unit is a front stage separating unit, and the second separating unit is a rear stage separating unit. Thus, the separation effect can be further optimized compared to the aforementioned structure, and the size of the structure can be further controlled.

The slop pail 1 can be designed as two detachably connected upper and lower parts, respectively, for accommodating the respective separating units therebetween, so that it is more convenient for a user to clean the inside of the slop pail 1. Further, the upper part is provided with a rear separating unit which is connected with the upper part and can be detached from the slop pail 1 together with the upper part, thus further facilitating the user to clean the interior of the slop pail 1 and each separating unit. The detachable connection in this case is very convenient by the fact that the upper part and the lower part are rotatably clamped at the connecting end.

The separating hood structure comprises a gas inlet 26 and a separating hood 2, gas-liquid mixture from the gas inlet 26 enters the sewage bucket 1 through the gas outlet end 6 of the first gas inlet pipe 3, the separating hood 2 changes the direction of the gas-liquid mixture by utilizing the blocking effect of the separating hood 2, in the embodiment, the direction is changed downwards, most sewage is remained in the sewage bucket 1, namely, in an annular liquid storage cavity formed between the first gas inlet pipe 3 and the sewage bucket 1, and gas flow bypasses the separating hood 2 and continues to upwards due to the suction of a suction source, so that certain gas-liquid separation is realized. In other words, the sewage and the sundries go down and the air goes up through the first blocking, so that the separation purpose is realized, and meanwhile, the airflow is favorably flowed to the next-stage separation unit.

As shown in figure 2, a closing piece 24 with an opening and closing structure is arranged between the separation cover 2 and the gas-liquid mixture inflow port, the closing piece 24 is opened when the scrubber sucks air and is closed when the scrubber stops sucking air, and therefore the device is compact in design structure, short in opening/closing time and timely in response.

The bottom of the separation cover 2 is provided with an elastic resetting structure which is connected with the closing piece 24, and the bottom of the separation cover 2 is used as a base, so that the structure is simple and compact, and the production and the manufacture are convenient. In addition, the design avoids arranging an additional structure at the periphery of the separation cover 2 to realize elastic reset, so that the structure is simplified on the one hand, and the shielding objects are reduced as much as possible at the inner periphery of the sewage bucket 1 on the other hand, thereby being beneficial to airflow flowing.

The bottom of the separation cover 2 is provided with a movable matching hole 27 axially arranged along the inlet of the gas-liquid mixture, the movable matching hole 27 is movably sleeved with a movable rod 28, one end of the movable rod 28 penetrates through the movable matching hole 27, the other end of the movable rod 28 is provided with a sealing part 24, a reset elastic part 25 is arranged between the bottom of the separation cover 2 and the sealing part 24, one end of the reset elastic part 25 abuts against the bottom of the separation cover 2, and the other end of the reset elastic part 25 abuts against the sealing part 24.

The movable sleeve joint adopts a movable sleeve joint structure for the swing of the movable rod 28, so that when the closing piece 24 is reset, the closing piece has swing displacement, namely transverse movement displacement, and therefore, in the long-term use process, the closing piece 24 can be better matched with a gas-liquid mixture inflow port for closing, and the durability and the reliability are obviously improved.

The surface of the side of the closing member 24 facing the gas-liquid mixture inflow port is provided as a guide surface for guiding the gas-liquid mixture to flow into the slop pail 1, in this case, a curved surface with both ends raised upward is used, which enables better inflow of the gas-liquid mixture, and in addition, the guide surface is provided to facilitate guiding the gas-liquid mixture to the peripheral wall of the separation hood 2 for better separation.

The opening and closing structure realizes opening and closing switching according to the pressure difference established by the pressure difference structure, for example, a dirty suction inlet, a gas-liquid mixture inflow inlet, a liquid storage cavity of the cleaning part 10 of the floor washing machine and a blower 32 suction inlet of the floor washing machine are communicated in sequence, the flow structure formed by the sequential communication serves as the pressure difference structure, and the opening and closing structure realizes opening and closing switching according to the pressure difference between the liquid storage cavity and the dirty suction inlet generated when the floor washing machine sucks air. The dirty suction inlet of the cleaning part 10 of the floor washing machine, the gas-liquid mixture inflow port, the liquid storage cavity and the suction inlet of the fan 32 of the floor washing machine are sequentially communicated to form a natural pressure difference environment to realize the opening and closing of the pressure difference, and the floor washing machine has the advantages of simple and compact structure, timely response and high integration level, can be of course in other applicable pressure difference structures, and can be applicable to all the requirements of the scheme of the invention.

The structure of fig. 2 is such that when the scrubber sucks air, a sufficient pressure difference is generated, so that the closing member 24 is opened against the elastic force of the return elastic member 25 to open the gas-liquid mixture inflow port, and when the scrubber stops sucking air, the pressure difference becomes small, and the return elastic member 25 returns the closing member 24 to close the gas-liquid mixture inflow port.

In this case the air flow coming out of the top of the centrifugal separation unit first passes through the filter 33 and then is discharged by the fan 32, which is a relatively short path because the fan 32 is located close to the top of the centrifugal separation unit. The second flow passage 8 is a flow passage between the filter 33 and the suction opening of the fan 32.

As shown in fig. 2 and 4, the centrifugal separation structure includes a gas inlet 26 and a centrifugal separation chamber 4, in this example, the gas inlet end 5 of the second gas inlet pipe 36 is the gas inlet 26, the gas-liquid mixture from the gas inlet 26 enters the centrifugal separation chamber 4 through the gas outlet end 6 of the second gas inlet pipe 36, the centrifugal separation chamber 4 separates gas and liquid by the centrifugal force of the rotation of the gas-liquid mixture, in this example, in order to form centrifugal rotation, a second cyclone 35 is provided in the second gas inlet pipe 36, and the second cyclone 35 guides the gas-liquid mixture from the gas inlet 26 to enter the centrifugal separation chamber 4 to form cyclone. Other structures can be adopted for forming the cyclone, for example, a tangential inlet is arranged on the peripheral wall of the centrifugal separation chamber 4, the tangential inlet is communicated with the second air inlet pipe 36, and the gas-liquid mixture from the second air inlet pipe 36 is guided through the tangential inlet to form the cyclone. For another example, the centrifugal separation chamber 4 is provided with a cyclone guide vane at the air outlet end 6 of the second air inlet pipe 36, and the gas-liquid mixture enters the centrifugal separation chamber 4 through the cyclone guide vane to form centrifugal rotation, thereby realizing centrifugal separation. For another example, the bottom of the centrifugal separation chamber 4 is connected with a second air inlet pipe 36, a second cyclone 35 is arranged in the second air inlet pipe 36, a cyclone guide vane is arranged at the bottom of the centrifugal separation chamber 4, the cyclone guide vane is marked as a first cyclone, and the gas-liquid mixture from the air inlet sequentially passes through the second cyclone 35 and the first cyclone, is guided into the centrifugal separation chamber, and forms a cyclone.

Furthermore, as shown in fig. 4, the collecting chamber 11 is provided with tangential guide surfaces 13 which are arranged tangentially to the rotating circumferential surface of the centrifugal separation chamber, which enables a better cyclone entry into the collecting chamber 11 and thus a better separation. Furthermore, as shown in fig. 2, the air outlet pipe 30 is arranged in the centrifugal separation cavity 4, and the air outlet pipe 30 is axially sleeved with the centrifugal separation cavity 4, so that air flow formed by the air outlet pipe 30 flows upwards and downwards from the air outlet pipe 30, the separated sewage is favorably kept in the centrifugal separation cavity 4, and meanwhile, the rotating air flow has enough time to separate and cannot be directly discharged. Furthermore, as shown in fig. 2 and 4, the collecting chamber 11 is provided with a baffle plate 31, and the height of the baffle plate 31 is higher than the bottom of the collecting chamber 11, so that the rotating airflow entering the collecting chamber 11 can be blocked to some extent, which is beneficial for separating the sewage and remaining in the collecting chamber 11. Furthermore, as shown in fig. 4, the collecting chamber 11 is provided with a baffle plate 31, in this embodiment, the baffle plate 31 is arranged at the cyclone outlet of the collecting chamber 11, and the baffle plate 31 is a component of the rotating circumferential surface of the centrifugal separation chamber 4, the structure is compact, the wall surface of the baffle plate 31 at one side of the centrifugal separation chamber 4 does not affect the cyclone of the centrifugal separation chamber 4, the height of the baffle plate 31 is higher than the bottom of the collecting chamber 11, the centrifugal separation chamber 4 is provided with an air outlet pipe 30, the air outlet pipe 30 is axially sleeved with the centrifugal separation chamber 4, and the height of the baffle plate 31 is higher than the air inlet 26 of the air outlet pipe 30, so that the rotating air flow entering the collecting chamber 11 can be blocked to a certain extent, which is beneficial to separating the sewage and remaining in the collecting chamber 11, and meanwhile, the separated sewage is not easy to enter the air outlet pipe 30 again, thereby ensuring the separation performance.

The centrifugal separation cavity 4 utilizes the centrifugal force of gas-liquid mixture rotation to separate gas and liquid, can obtain better separation effect, and simultaneously, the setting of collection chamber 11, on the one hand, collects chamber 11 and has promoted gas-liquid separation, and on the other hand makes the sewage that centrifugal separation came out concentrate to collection chamber 11 fast, greatly improves the separation effect, consequently has better gas-liquid separation performance.

The liquid discharge outlet that collects room 11 is equipped with check valve 12, when centrifugal separation unit during operation, this check valve 12 seals the liquid discharge outlet, when centrifugal separation unit stop work, this check valve 12 opens the liquid discharge outlet and supplies sewage to pass through the liquid discharge outlet and discharge to the slop pail, consequently, when centrifugal separation unit during operation, can ensure that the air current in the slop pail 1 can directly not be gone into centrifugal separation chamber 4 through the drain cluster, on the other hand makes centrifugal separation chamber 4 negative pressure higher than slop pail 1, make the negative pressure that fan 32 produced as high-efficient suction source, energy utilization is high, thereby make the air current flow more powerful, when centrifugal separation unit stop work, check valve 12 opens the liquid discharge outlet, discharge sewage to slop pail 1. In conclusion, the scheme of the invention is beneficial to preventing the centrifugal separation unit and the sewage bucket 1 from influencing each other. In this embodiment, the check valve 12 is a rubber or silica gel valve plate, and when the centrifugal separation unit is in operation, the check valve 12 automatically closes the liquid discharge port by using the pressure difference between the centrifugal separation chamber 4 and the slop pail 1, and when the centrifugal separation unit stops operating, the check valve 12 is opened in one direction to discharge the slop pail 1 with the decrease or disappearance of the pressure difference. Of course, the check valve 12 may have other structures, and the control structure for one-way opening may also have other structures, and all that meets the requirements of the scheme of the present invention may be applicable.

As can be seen from the axial arrangement of the separation unit and with reference to the drawings, in this example the discharge opening is located at the bottom of the centrifugal separation chamber 4, so that when the centrifugal separation unit stops operating, the one-way valve 12 opens the discharge opening and the sewage flows naturally towards the slop pail 1, and the path is shortest. The aforementioned bottom arrangement, combined with the arrangement of the collecting chamber 11, i.e. the drain port is located at the bottom of the collecting chamber 11, will achieve better separation and drainage effects.

When the first cyclone is arranged at the bottom of the centrifugal separation chamber 4 and the second air inlet pipe 36 is connected to the bottom of the centrifugal separation chamber 4, the second air inlet pipe 36 is used for increasing the distance between the air inlet end 5 and the first cyclone, such a design is beneficial to accelerating the cyclone, and in addition, sewage which is remained in the sewage bucket 1 is not easy to flow into the first cyclone again or further to the centrifugal separation chamber 4.

Furthermore, an axial flow passage, i.e., a second gas inlet pipe 36, is coaxially arranged along the axial direction of the centrifugal separation chamber 4 at the lower side of the bottom of the centrifugal separation chamber 4, the gas inlet end 5 axially conveys the gas-liquid mixture through the axial flow passage, and the gas-liquid mixture enters the centrifugal separation chamber from the bottom and/or the peripheral wall of the centrifugal separation chamber. Therefore, the arrangement of the air outlet pipe 30 is combined, the air flow flowing is facilitated, the separation effect is improved, the effective utilization of the suction negative pressure energy formed by the suction source is facilitated, in addition, the arrangement structure is facilitated, and the structure is compact.

Furthermore, the bottom of the centrifugal separation chamber 4 is provided with an inlet for the gas-liquid mixture, and a partition is provided between the inlet and the inlet of the gas outlet pipe 30, in this case, the partition is the diffusion cover 37, so that, on one hand, the gas-liquid mixture does not directly flow into the gas outlet pipe 30, on the other hand, the gas-liquid mixture can enter the gas outlet pipe 30 after the centrifugal separation chamber 4 performs cyclone separation as much as possible, which is more favorable for improving the separation efficiency, and on the other hand, when the first cyclone is provided, the first cyclone can be used as the partition, which simplifies the structure.

Furthermore, an annular separation flow passage is formed between the partition and the inlet of the centrifugal separation chamber 4, so that the flow of the gas-liquid mixture is facilitated. When a first cyclone is provided, the annular spaced flow passages may be adapted to receive the cyclone blades of the first cyclone.

In order to have stronger cyclone, the annular interval flow channel can be arranged to be in a diameter-variable arrangement, for example, the annular interval flow channel is provided with at least one narrowing section 38, the narrowing section 38 is arranged between the inlet and the outlet of the annular interval flow channel, the cross sections of the annular flow channel at the inlet and the outlet are all larger than that of the annular flow channel at the narrowing section, thus the airflow can be accelerated by the narrowing section 38, and the cross sections of the annular flow channel at the inlet and the outlet are all larger than that of the annular flow channel at the narrowing section, thereby being beneficial to forming stronger cyclone.

In addition, in fig. 2, because the cyclone blades of the second cyclone 35 provide the structure formed by the cyclone, the annular interval flow channel does not contain the cyclone blades of the first cyclone, so that the annular interval flow channel is more unobstructed, thus being more favorable for the flow of gas-liquid mixture and strengthening the cyclone, and in addition, the reducing setting of the annular interval flow channel is more effective.

In addition, the inlet of the centrifugal separation cavity 4 is provided with the diffusion cover 37, the diffusion cover 37 serves as the partition part, the diffusion cover 37 guides the gas-liquid mixture coming from the second gas inlet pipe 36 to diffuse and enter the centrifugal separation cavity 4, so that on one hand, stronger cyclone is favorably formed, on the other hand, the gas flow is favorably and smoothly whirlwind in the centrifugal separation cavity 4, and on the other hand, the diffusion cover 37 and the partition part are the same component, so that the structure is simplified, in short, the better separation effect is favorably realized, and meanwhile, the structure is simplified. In this example, the diffusion cover 37 is formed in an inverted umbrella shape.

Example two:

as shown in figure 3, the opening and closing structure is changed into a duckbill valve 29, which is opened when the scrubber sucks air and closed when the scrubber stops sucking air, so that the structure is simpler, and the performance is better. The closure 24 configuration of the first embodiment provides additional guidance while providing better reusability of the closure 24.

Example three:

the first and second embodiments are both mechanical structures to be opened and closed, and the third embodiment adopts an opening and closing structure controlled by a control unit of the floor washing machine, such as opening and closing by an electromagnetic switch, so that the design is favorable for later-stage realization and liquid level detection structure linkage, such as when the liquid level reaches a certain value, the active closing of a gas-liquid mixture inflow port is favorable for realizing more accurate control, and the machine performance is improved.
