Description

[0002] The floor washing machine can be generally divided into a floor washing assembly and a suction source, and the two parts are connected together and generally not disassembled, so that the floor washing machine has its own suction source, in other words, the suction source is special. The reason for this design is that the working condition of the floor washing machine is generally wet mopping the ground, and the air-liquid mixture is sucked in. Although the air-liquid separation unit is provided, the suction source still needs to be specially capable of working in the airflow state with a large humidity.

[0003] From the foregoing, since the suction source has been designed for the humidity working condition, the existing floor washing machine does not judge the humidity of the airflow, and it is unnecessary to judge according to the existing design idea. However, the present applicant believes that this is not the case. The judgment of the humidity of the airflow is of great significance, and the judgment of the humidity of the airflow is beneficial to use the dust collector host as the suction source, thereby providing certain basic conditions for further development of the floor washing machine using the dust collector host.

DETAILED DESCRIPTION

[0051] The following description is presented to enable any person skilled in the art to practice the present application as claimed. The embodiments disclosed in the following description and claims are only exemplary and are not intended to exhaustively describe all possible implementations having the features described herein. The present application is defined by the appended claims and their equivalents.

[0052] The present application is further described in detail by the following:

[0053] As Figure 19 , 20 , 21, 22, a floor cleaning assembly adopting the scheme of the present application, specifically, the floor cleaning assembly comprises a cleaning part 13 and a separation structure, the cleaning part 13 is connected in communication with the separation structure through a first flow channel 10, the separation structure is connected in communication with a second flow channel 11, the second flow channel 11 is used to be connected in communication with a suction source, the separation structure and / or the second flow channel 11 is provided with a humidity filtering unit 44, and the floor cleaning assembly further comprises humidity detection structure used to detect the humidity condition of the humidity filtering unit 44, the humidity detection structure is used to provide a humidity signal of the humidity filtering unit 44 to a control module of the floor cleaning machine. The cleaning part 13 is provided with a suction port, through which a gas-liquid mixture is sucked in, such as Figure 19 , 20The floor cleaning unit 13 shown in 21 and 22 includes a circular mop unit that cleans the floor by rotating, but is not limited to a circular mop unit. It can also be other structures, such as the roller brush structure that will be exemplified below.

[0054] The number of moisture filter units 44 can be one or more; this example uses one.

[0055] The outlet side of the separation structure has a cavity 50, and a moisture filter unit 44 is installed inside the cavity 50. The airflow from the outlet flows to the suction source after being filtered by the moisture filter unit 44. This position and structure can, on the one hand, detect changes in humidity more promptly, and on the other hand, prevent abnormal airflow from directly hitting the suction source. Furthermore, the cavity design is conducive to providing a larger flow rate.

[0056] The opened cavity 50 has an opening into which the moisture filter unit 44 is installed. The cavity 50 is detachably connected to the separation structure. Removing the separation structure exposes the opening, and after the separation structure is installed, the separation structure closes the opening. Figure 19 , 22 As shown, a moisture filter unit 44 is installed along the axial direction of the cavity 50. This design is simple and compact, and facilitates the replacement of the moisture filter unit 44 as well as the cleaning of the cavity 50.

[0057] like Figure 20 , 21 As shown, the outlet of the separation structure is equipped with a baffle wall, and the baffle wall has a guide channel 33. This guide channel 33 is used to extend the airflow travel distance, and the moisture filtration unit 44 is located downstream of the guide channel 33. In this example, the guide channel 33 is only provided in the last stage separation unit of the separation structure, but it is not limited to this example. See also... Figure 8 Understand the flow channel 33.

[0058] The specific structure of the flow guide channel 33 in the final separation unit is as follows: a baffle 29 is connected to the upper side of the top cover 28, and a flow guide channel 33 is provided between the baffle 29 and the top cover 28. The lower surface of the baffle 29 is the baffle wall. The top cover 28 has a through hole as an airflow channel, and the outlet of the airflow channel faces the baffle wall. The baffle wall is provided with the flow guide channel 33, and the outlet is connected to the moisture filtration unit 44 through the flow guide channel 33. The flow guide channel 33 is used to extend the airflow distance and play a certain buffering role for the airflow, which helps to prevent sewage from entering. This helps to protect the moisture filtration unit and thus ensure the usability of the moisture filtration unit.

[0059] In this example, the flow guide channel 33 is provided with a distribution channel 49, which distributes the airflow to the moisture filtering unit 44. In this way, the performance of the moisture filtering unit 44 can be better exerted.

[0060] As shown in Figure 21 , 22 , the moisture filtering unit 44 adopts a cylindrical filter, which is sleeved with an air outlet 48, which is part of the second flow channel 11, or which is independently provided and communicates with the second flow channel 11. In this example, the air outlet 48 is part of the second flow channel 11. The air outlet 48 is tubular, and the air outlet 48 is provided with a plurality of air inlet holes, which are attached to the surface of the cylindrical hole of the cylindrical filter. The distribution channel 49 is located outside the cylindrical hole and is arranged around the cylindrical hole. In this way, the airflow mainly passes through the cylindrical filter and then enters the air outlet 48, and is then drawn out by the suction source through the second flow channel 11.

[0061] The cylindrical filter has a large filtering volume, can be used for a long time, and has good filtering effect, which can better protect the suction source. In addition, the distribution channel 49 limits the flow path of the airflow, so that the cylindrical filter can better exert its effect.

[0062] The humidity detection structure includes a humidity sensor, and the detection part 45 of the humidity sensor is in contact with or located in the moisture filtering unit 44. In this example, as shown in Figure 22 , after the moisture filtering unit 44 is assembled into the container cavity 50, the detection part 45 is located in the moisture filtering unit 44, or said to be inserted into the moisture filtering unit 44, so that the detection can be better.

[0063] The detection part 45 is located inside the container cavity 50 and faces the moisture filtering unit 44. After the moisture filtering unit 44 is assembled into the container cavity 50, the detection part 45 is in contact with or located in the moisture filtering unit 44 through the movement of the assembly. In this way, the installation is convenient, and at the same time, the installation can more reliably guarantee the connection relationship between the detection part 45 and the moisture filtering unit 44, without the need for special attention from the user, greatly facilitating the user's use.

[0064] The above-mentioned floor washing assembly further includes a clean water bucket 22, and the separation structure, the container cavity 50, and the clean water bucket 22 are sequentially arranged from bottom to top. In this way, the structure is compact, the layout is reasonable, and the use is convenient.

[0065] The upper end of the separation structure is detachably connected with the lower end of the container cavity 50, the lower end of the container cavity 50 is provided with an opening for assembling the moisture filtering unit 44, and the upper end of the container cavity 50 is detachably connected with the lower end of the clean water bucket 22. In this way, it is more conducive to compact structure, reasonable layout, and convenient use.

[0066] The lower end of the separation structure is provided with a connecting structure, which is used for connecting when the upper end of the separation structure is sleeved with the opening of the containing cavity 50. When the separation structure is installed, the upper end of the separation structure is first partially sleeved with the opening of the containing cavity 50, and then the lower end of the separation structure is connected with the connecting structure. After the connection is completed, the connecting structure fixes the relative position of the upper end of the separation structure and the opening of the containing cavity 50. When the separation structure is removed, the lower end of the separation structure is first disconnected from the connecting structure, and then the upper end of the separation structure is separated from the opening of the containing cavity 50 to expose the opening of the containing cavity 50. In this way, the assembly relationship can be significantly simplified, which is more conducive to compact structure, reasonable layout and convenient use.

[0067] The connecting structure includes a first inclined part and a second inclined part 47 connected with each other. The first inclined part is arranged at the lower end of the separation structure, and the second inclined part 47 is fixedly arranged. The connection of the lower end of the separation structure with the connecting structure refers to the connection of the first inclined part and the second inclined part 47. In this way, the structure is simple and compact, the connection is reliable and stable, and in addition, the user can use it conveniently.

[0068] The separation structure is provided with a first interface as an air inlet of the separation structure at the first inclined part, and the second inclined part 47 is provided with a second interface 46 which is communicated with the cleaning part 13 through the first flow channel 10. When the separation structure is installed, the first interface is in sealed connection with the second interface 46. In this way, the connection of the separation structure and the containing cavity 50 is realized at the same time, and the sealed connection of the first interface and the second interface 46 is also realized at the same time, which greatly simplifies the connection, is more conducive to simple and compact structure, reliable and stable connection, and in addition, the user can use it conveniently.

[0069] Figure 19 The arrows shown represent the connection direction of the separation structure and the containing cavity 50 and the assembly direction of the containing cavity 50 to the wet gas filtering unit 44, which are for reference.

[0070] Figure 20 The arrows shown represent the flow direction of the airflow. The gas-liquid mixture is sucked through the suction port of the cleaning part 13, and then sequentially passes through the first flow channel 10, the separation structure, the wet gas filtering unit 44, the second flow channel 11 and enters the suction source. The shape and direction represented by these arrows are for reference.

[0071] In this example, the wet gas filtering unit 44 adopts filter cotton, and of course other materials can also be used. The material can have the performance of filtering water vapor and can also ventilate.

[0072] The separation structure of the above-mentioned floor washing assembly includes a plurality of separation units, which is similar to the separation structure of the floor washing assembly or floor washing machine described below, the main difference being that the last separation unit downstream of the above-mentioned floor washing assembly is provided with a wet gas filtering unit 44, instead of being directly communicated with the suction source through the second flow channel 11, and the above-mentioned floor washing assembly does not additionally provide a gas flow humidity detection sensor 23. Of course, the above-mentioned floor washing assembly can also be provided with a gas flow humidity detection sensor 23, thereby better protecting the suction source, i.e., humidity detection of the gas flow, and if the humidity exceeds the set threshold, the suction source can be stopped in time for protection, thereby forming a multiple protection scheme. The specific content of the separation structure and related structures is described below and will not be repeated here. In addition, the above-mentioned floor washing assembly uses the same structure as the water shortage detection of the floor washing assembly or floor washing machine described below for water shortage detection of the clean water tank 22, which will not be repeated here.

[0073] The above-mentioned floor washing assembly can be used as a functional component of a vacuum cleaner and is detachably connected with the vacuum cleaner, wherein it further includes a bracket 14, the cleaning part 13 is connected with the bracket 14, the separation structure is connected with the bracket 14, the bracket 14 is provided with the second flow channel 11, the bracket 14 is provided with a detachable connection structure and an electrical connection terminal for detachable connection with the vacuum cleaner, the detachable connection structure enables the second flow channel 11 to be detachably connected with the vacuum cleaner, and the electrical connection terminal is electrically connected with the control module of the vacuum cleaner, which serves as the control module of the floor washing machine. The foregoing structure is similar to the structure of the floor washing assembly or floor washing machine described below, and the specific content is described below and will not be repeated here.

[0074] The above-mentioned scheme can be used to modify the floor washing assembly or floor washing machine described below, so that the floor washing assembly or floor washing machine described below also has a wet gas filtering unit 44 and related structures, thereby providing better protection for the suction source, and making it a feasible and reliable scheme to use a vacuum cleaner main machine as a suction source for the floor washing machine.

[0075] Figure 11 、 12 , 13 is a schematic view of a floor washing assembly without a cleaning water spray hole 38 and related structures, and Figure 16 、 17 , 18 is a schematic view of a floor washing assembly provided with a cleaning water spray hole 38 and related structures, except for the cleaning water spray hole 38 and related structures, Figure 11 、 12 , the structure of the floor washing assembly shown in 13 and Figure 16 、 17 , the structure of the floor washing assembly shown in 18 is basically the same, so if necessary, they can be referred to each other and compared.

[0076] Figure 16 、 17The washing assembly shown in FIGS. 18 comprises a wet mopping cleaning part 13 and a support 14, the wet mopping cleaning part 13 is connected with the support 14, the wet mopping cleaning part 13 is connected with the gas-liquid separation structure through the first flow channel 10, the gas-liquid separation structure is connected with the support 14, the support 14 is provided with the second flow channel 11, the gas-liquid separation structure is connected with the second flow channel 11, and the second flow channel 11 is used for being connected with the suction source. The first flow channel 10 is provided with a cleaning water spraying hole 38, which is used for independent water spraying cleaning and / or water spraying cleaning cooperating with suction. In this case, the program is set to be able to independently spray water for cleaning and also to spray water for cleaning cooperating with suction, so as to give users more selection. If it is simplified, the cleaning water spraying hole 38 is preferably used for water spraying cleaning cooperating with suction.

[0077] Since the first flow channel 10 is the front entrance and flow channel of the gas-liquid mixture, the cleaning water spraying hole 38 is arranged in the first flow channel 10, which can clean the first flow channel 10. If water is sprayed and suction is performed at the same time, the gas-liquid mixture for cleaning the first flow channel 10 is sucked into the sewage bucket 1, so that the sewage cannot flow out, thereby avoiding contamination of the external environment. At the same time, a small number of cleaning water spraying holes 38 can be arranged to better clean the first flow channel 10. On the other hand, the sewage bucket 1 and the separation structure can also be cleaned to a certain extent. This is because, as the first flow channel 10 is cleaned, the gas-liquid mixture formed during the cleaning of the first flow channel 10 becomes cleaner and cleaner. When the clean gas-liquid mixture is sucked into the sewage bucket 1 and the separation structure by the suction source, the sewage bucket 1 and the separation structure are cleaned to a certain extent. The longer the cleaning time, the more obvious the effect. If the first flow channel 10 is cleaned, the sewage in the sewage bucket 1 is poured out, and then clean water is sprayed into the first flow channel 10 while the suction source is sucking, which can better clean the sewage bucket 1 and the separation structure. As described above, the cleaning is automatically completed without manual flushing. Since the automatic cleaning to a certain extent reduces the breeding of bacteria, it helps to reduce odors. As described above, compared with the existing user disassembly and flushing, the cleaning workload of the user is greatly reduced. In summary, the user's experience can be greatly improved.

[0078] As shown in FIGS. 18, Figure 16 , 17As shown in Figure 18, in this example, cleaning spray holes 38 are provided near the wet mopping cleaning section 13 in the first flow channel 10. This allows for effective cleaning of the entire first flow channel 10 with fewer cleaning spray holes 38, in conjunction with suction from a suction source. Multiple cleaning spray holes 38 are arranged circumferentially around the first flow channel 10, resulting in better and more efficient cleaning. A third flow channel 12 is provided between the clean water tank 22 and the wet mopping cleaning section 13. The third flow channel 12 has two branches: a first branch 39 and a second branch 40. The first branch 39 delivers water from the third flow channel 12 to the wet mopping cleaning section 13, and the second branch 40 delivers water from the third flow channel 12 to the cleaning spray holes 38. This layout facilitates the arrangement of the cleaning spray holes 38.

[0079] The third channel 12, the first branch 39, and the second branch 40 are all water supply hoses. The water inlet end of the water supply hose is connected to the clean water tank 22. The water outlet end of the first branch 39 is connected to the water outlet located on one side of the wet mopping cleaning part 13. The water outlet end of the second branch 40 is connected to the cleaning spray hole 38.

[0080] Four cleaning spray holes 38 are provided and are evenly distributed around the first flow channel 10. The water flow from the second branch 40 is divided into four paths by the distributor 43, each path connected to one cleaning spray hole 38, as shown below. Figure 16 , 18 As shown, Figure 18 It is a cross-sectional view showing three of the cleaning water spray holes 38.

[0081] The first flow channel 10 in this example uses a telescopic corrugated pipe as the main body. If a pipe with a smooth inner wall is used, it will be more conducive to the flow of gas-liquid mixture, less likely to accumulate dirt, and also easier to clean. Therefore, the reduction of folds is beneficial to cleaning and hygiene.

[0082] like Figure 16 As shown, the first branch 39 is equipped with a first water pump 41, and the second branch 40 is equipped with a second water pump 42. This allows for separate control, adapting to the different water spraying requirements of the wet mopping cleaning section 13 and the cleaning spray nozzles 38, providing high flexibility. At the same time, the first water pump 41 and the second water pump 42 also serve as control valves. The first water pump 41 can independently control the connection between the first branch 39 and the third flow channel 12, and the second water pump 42 can independently control the connection between the second branch 40 and the third flow channel 12. Furthermore, there is no need to set up additional control valves, as the pressurization control is integrated, simplifying the structure.

[0083] The spray angle of the cleaning spray nozzle 38 can be different and can be designed and determined according to the first flow channel 10, water pressure, etc. The spray shape of the cleaning spray nozzle 38 can be a water column, a water mist, or other shapes.

[0084] likeFigure 11 、 12 As shown in FIG. 13, the wet mop cleaning part 13 adopts a rolling brush structure. When cleaning the ground, the rolling brush structure mops the ground on one hand and sucks the dirt into the suction source through the flow channel on the other hand. If there is water on the ground, the air-liquid mixture is sucked in. Or the wet mop cleaning part 13 is a wetted wet mop cleaning part 13. The wet mop cleaning part 13 is squeezed by the squeegee. Thus, while mopping the ground, the squeegee squeezes out the sewage. Thus, when the suction source sucks, the air-liquid mixture is sucked in.

[0085] In order to continuously wet the wet mop cleaning part 13, the wet mop cleaning part 13 is circumferentially provided with a water injection nozzle. The water injection nozzle is connected to the clean water tank 22 through the third flow channel 12. In this example, the clean water tank 22 is coaxially arranged with the air-liquid separation structure and is located on the upper side of the air-liquid separation structure.

[0086] The water supply hose is provided with a water shortage detection sensor 17 which can detect whether there is water in a non-contact manner. The water pump 16 is located at the rear end of the water shortage detection sensor 17. The signal obtained by the water shortage detection sensor 17 can make the wet mop cleaning part 13 and the suction source stop working in time or prompt the user of water shortage, water adding, water presence, etc.

[0087] The water shortage detection sensor 17 is arranged in the third flow channel 12, not in the clean water tank 22. When the clean water tank 22 supplies water to the wet mop cleaning part 13, once there is no water flowing through the position where the water shortage detection sensor 17 is located, the water shortage detection sensor 17 detects that there is no water flowing through and generates a signal. The control module of the scrubber judges that there is no water according to the set water absence time delay and stops working or judges that there is no water immediately and stops working. By using the aforementioned signal, the control module of the scrubber can also be set to remind the user. The reminding means can be an audible and visual alarm, etc. Since the water is judged in the third flow channel 12, on one hand, the judgment of the water condition is more accurate and the water in the clean water tank 22 can be used as much as possible. That is to say, when it is detected that there is no water, the water in the clean water tank 22 is basically used up. There is basically no water in the clean water tank 22. The detection is more stable. On the other hand, before the water is completely used up, the control module of the scrubber can stop working and stop spraying water from the cleaning spray hole 38 in time according to the water shortage signal. Thus, there are at least two advantages. Advantage one is that the wet mop cleaning part can stop working while mopping the ground. At this time, the wet mop cleaning part is not very dirty because it is still supplied with clean water from a point in the water supply hose. Thus, after stopping in time, the ground will not be dirty, which is conducive to cleaning. Advantage two is that when there is no water during cleaning, it means that the water in the cleaning spray hole 38 will be used up soon. Thus, the user can be reminded in time to fill the clean water tank 22 with water before cleaning, which can improve the cleaning efficiency.

[0088] The water delivery hose, water pump 16, and water shortage detection sensor 17 are mainly located inside the rear cover 15 of the bracket 14, which facilitates manufacturing and also helps in designing the overall appearance of the floor cleaning assembly.

[0089] The power to rotate the wet mopping cleaning unit 13 can be supplied by its own battery or by a suction source.

[0090] The gas-liquid separation structure and / or the second flow channel 11 are provided with an airflow humidity detection sensor 23, which is used to provide airflow humidity signals to the control module of the floor scrubber.

[0091] The gas-liquid separation structure includes one or more separation units. In this example, the gas-liquid separation structure includes two separation units: a first separation unit and a second separation unit.

[0092] like Figure 1 , 5 As shown, an airflow humidity detection sensor 23 is provided on the exhaust pipe 24 that is connected to the air outlet 25 of the last stage separation unit. The airflow humidity detection sensor 23 is set close to the side of the separation unit, that is, close to the air outlet side of the gas-liquid separation structure. In this way, it is set close to the side of the separation unit, so that it can be detected as early as possible, thereby stopping the suction source in time, which is more conducive to protecting the suction source.

[0093] Exhaust pipe 24 is mainly used to connect to the suction source. Figures 1 to 9 For illustrative purposes only, the lower end of the exhaust pipe 24 is shown. The length of the exhaust pipe 24 is designed as needed, so that the airflow humidity detection sensor 23 can be set along the exhaust pipe 24.

[0094] The floor cleaning assembly serves as a functional component of the vacuum cleaner and is detachably connected to the vacuum cleaner. The bracket 14 is provided with a detachable connection structure that allows the second flow channel 11 to be detachably connected to the vacuum cleaner.

[0095] The detachable connection includes a connector 18, a button 19, and a snap-fit ​​protrusion 20, such as... Figure 14As shown, the plug-in pipe 18 is connected with the plug-in suction port 37 of the handheld vacuum cleaner main machine 27, when inserted, the clamping protrusion 20 is pressed down by the inner surface of the plug-in suction port 37, the plug-in pipe 18 can be smoothly inserted into the plug-in suction port 37, the plug-in suction port 37 is provided with a recess matched with the clamping protrusion 20, when the plug-in pipe 18 is plugged in place, the clamping protrusion 20 is matched with the recess to achieve locking, without pressing the button 19, the plug-in pipe 18 and the plug-in suction port 37 cannot be separated from each other, the button 19 is connected with the clamping protrusion 20, when the button 19 is pressed, the clamping protrusion 20 will be retracted, so as to realize the separation of the clamping protrusion 20 and the recess. The foregoing structure, on the one hand, realizes the reliable detachable connection of the floor cleaning assembly and the handheld vacuum cleaner main machine 27, on the other hand, realizes the communication connection between the second flow channel 11 and the suction source, so as to use the handheld vacuum cleaner main machine 27 as the suction source.

[0096] In order to realize the power supply and control by the handheld vacuum cleaner main machine 27, the floor cleaning assembly is also provided with an electrical connection terminal 21, when the plug-in pipe 18 is connected with the plug-in suction port 37, the electrical connection terminal 21 will be electrically connected with the handheld vacuum cleaner main machine 27 and the control signal line, so as to supply power to the power-consuming part of the floor cleaning assembly on the one hand, and control the power-consuming part through the handheld vacuum cleaner main machine 27 on the other hand, such as the wet mop cleaning part 13, the water pump 16, various sensors and the like.

[0097] As shown in the figure, Figure 14 It is a floor cleaning machine, the floor cleaning assembly and the suction source can be separated, and in order to better adapt to the vacuum cleaner as the suction source, the gas-liquid separation structure is provided with a plurality of separation units, and the airflow humidity detection sensor 23 is arranged, so as to realize the purpose of using the vacuum cleaner as the suction source, such floor cleaning machine can be better popularized, solves the problem of needing to specially configure the suction source, reduces the threshold of purchase and use, and has important significance.

[0098] In this example, as shown in the figure, Figure 14 The suction source adopts the handheld vacuum cleaner main machine 27, and a floor cleaning function of the handheld vacuum cleaner is provided.

[0099] For the gas-liquid separation structure, a good gas-liquid separation structure design is not only beneficial to gas-liquid separation, but also beneficial to the effectiveness and reliability of the airflow humidity detection sensor:

[0100] As shown in the figure, Figure 1 A three-dimensional schematic view of a gas-liquid separation structure is disclosed, including a sewage tank 1 and a separation unit, the separation unit is two or more, the airflow channels of each separation unit are sequentially communicated, and the sewage separated by each separation unit is discharged into the sewage tank 1.

[0101] In this case, a sewage bucket 1 is adopted, which is provided with two separation units, so that the separation effect is good, and the size of the structure can be controlled well. In addition, the sewage bucket 1 is easy to disassemble and clean, and is convenient for users to use. Of course, there can be more than two separation units, and there can be more than one sewage bucket 1.

[0102] As shown in Figure 13 , the sewage bucket 1 is provided with two separation units, which are a first separation unit and a second separation unit. The first separation unit adopts a separation cover structure, and the second separation unit adopts a centrifugal separation structure. The first separation unit includes a separation cover 2 and a first air inlet pipe 3 arranged in an upper and lower manner. The first air inlet pipe 3 is used to input a front-stage gas-liquid mixture. In this case, the second separation unit includes a centrifugal separation cavity 4 and a second air inlet pipe 5 arranged in an upper and lower manner. The air inlet end 6 of the second air inlet pipe 5 is located above the separation cover 2, and the air outlet end 7 of the second air inlet pipe 5 is located in the centrifugal separation cavity 4. Of course, other structures can also be adopted, such as canceling the second air inlet pipe 5. The second separation unit includes the centrifugal separation cavity 4 and the air inlet end 6 provided in the centrifugal separation cavity 4. The centrifugal separation cavity 4 is located above the separation cover 2. The combination of the first separation unit and the second separation unit can further optimize the separation effect and further control the size of the structure.

[0103] As shown in Figure 2 , 3 , 4, 13, the first separation unit and the second separation unit are coaxially arranged. In this case, specifically, the second separation unit and the first separation unit are arranged in an upper and lower manner along the axis direction of the sewage bucket 1. The first separation unit serves as a front-stage separation unit, and the second separation unit serves as a rear-stage separation unit. In this way, compared with the foregoing structure, the separation effect can be further optimized, and the size of the structure can be further controlled.

[0104] As shown in Figure 2 , the separation cover 2 is connected with a floating mechanism 8. The floating mechanism 8 is used to drive the separation cover 2 to move up and down according to the sewage liquid level. The top 9 of the separation cover 2 is used to close / open the air inlet end 6 of the second air inlet pipe 5 according to the sewage liquid level. When the sewage reaches a certain height, the top 9 of the separation cover 2 moves upward to a position for closing the air inlet end 6 of the second air inlet pipe 5, so as to avoid the sewage from being sucked into the second air inlet pipe 5 due to continuous work, and to avoid the suction source from being sucked. Such a height is defined as the sewage being full, and the sewage needs to be poured out for use. In order to guide the movement of the separation cover 2, the separation cover 2 is further connected with a guide structure 35 which is guided and matched with the inner surface of the sewage bucket 1. The guide structure 35 and the floating mechanism 8 can adopt various structures. For example, the guide structure 35 is a guide plate, and the floating mechanism 8 is a float structure.

[0105] As shown in Figure 1 , 2As shown in Figure 3, the sewage tank 1 comprises two detachably connected parts, namely the upper part 1.1 and the lower part 1.2. The space between the upper and lower parts is used to accommodate the various separation units, which makes it more convenient for users to clean the inside of the sewage tank 1. Furthermore, the upper part 1.1 is equipped with a downstream separation unit, which is connected to the upper part 1.1 and can be detached from the sewage tank 1 together with the upper part 1.1. This further facilitates the user to clean the inside of the sewage tank 1 and the various separation units.

[0106] In this example, the detachable connection is achieved by rotating and snapping the upper part 1.1 and the lower part 1.2 together at the connection end, which is a very convenient connection structure.

[0107] like Figure 1 , 2 As shown in Figures 3 and 13, the separation hood structure includes an air inlet 26 and a separation hood 2. The gas-liquid mixture coming from the air inlet 26 enters the sewage tank 1 through the air outlet 7 of the first air inlet pipe 3. Due to the obstruction of the separation hood 2, the separation hood 2 uses its obstruction effect to change the direction of the gas-liquid mixture. In this example, the direction is changed downward. So most of the sewage remains in the sewage tank 1, while the airflow continues upward after bypassing the separation hood 2 due to the suction of the suction source, thereby achieving a certain degree of gas-liquid separation.

[0108] like Figure 4 , 5 As shown in Figures 6, 7, 8, 9, and 13, the centrifugal separation structure includes an air inlet 26 and a centrifugal separation chamber 4. In this example, the air inlet 6 of the second air inlet pipe 5 is the air inlet 26. The gas-liquid mixture from the air inlet 26 enters the centrifugal separation chamber 4 through the air outlet 7 of the second air inlet pipe 5. The centrifugal separation chamber 4 uses the centrifugal force of the rotating gas-liquid mixture to separate the gas and liquid. In this example, to form centrifugal rotation, a cyclone separator 32 is provided at the air outlet 7 of the second air inlet pipe 5 in the centrifugal separation chamber 4. The gas-liquid mixture enters the centrifugal separation chamber 4 after passing through the cyclone separator 32, forming centrifugal rotation, thereby achieving centrifugal separation. Other structures can also be used to form the cyclone, such as... Figure 15 As shown, the centrifugal separation chamber 4 is provided with a tangential guide inlet 36, which is connected to the second air inlet pipe 5. The gas-liquid mixture from the second air inlet pipe 5 is guided by the tangential guide inlet 36 to form a cyclone.

[0109] like Figure 9 , 13 As shown, the centrifugal separation chamber has a collection chamber 4.1 on its surrounding wall. The collection chamber 4.1 has a drain outlet. The collection chamber 4.1 is used to collect wastewater and discharge it into the wastewater tank 1 through the drain outlet. This achieves better separation and facilitates the discharge of wastewater into the wastewater tank 1. Furthermore, as... Figure 9As shown, the collection chamber 4.1 is provided with a tangential guide surface 4.3 designed tangentially to the rotating circumferential surface, so that the cyclone can better enter the collection chamber 4.1, thus bringing a better separation effect. Further, as shown in Figure 6 , 7 , 13, the centrifugal separation cavity 4 is provided with an air outlet pipe 31 axially sleeved with the centrifugal separation cavity 4, so that the air flow is formed to flow out of the air outlet pipe 31 first upwards and then downwards, which is beneficial to keep the separated sewage in the centrifugal separation cavity 4, while allowing the rotating air flow to have sufficient time for separation without being directly discharged. Further, as shown in Figure 13 , the collection chamber 4.1 is provided with a flow baffle 34, the height of which is higher than the bottom of the collection chamber 4.1, so that the rotating air flow entering the collection chamber 4.1 is blocked to some extent, which is beneficial to separate the sewage and keep it in the collection chamber 4.1. Further, as shown in Figure 13 , the collection chamber 4.1 is provided with a flow baffle 34, which is arranged at the cyclone outlet of the collection chamber 4.1 in this example, the height of the flow baffle 34 is higher than the bottom of the collection chamber 4.1, and the centrifugal separation cavity 4 is provided with an air outlet pipe 31 axially sleeved with the centrifugal separation cavity 4, the height of the flow baffle 34 is higher than the air inlet 26 of the air outlet pipe 31, so that the rotating air flow entering the collection chamber 4.1 is blocked to some extent, which is beneficial to separate the sewage and keep it in the collection chamber 4.1, while the separated sewage is not easy to re-enter the air outlet pipe 31, thus ensuring the separation performance.

[0110] The liquid outlet of the collection chamber 4.1 is provided with a one-way valve 4.2, which is beneficial to prevent the air flow in the sewage bucket 1 from entering the centrifugal separation cavity 4 through the sewage outlet, and on the other hand, the pressure in the centrifugal separation cavity 4 is higher than that in the sewage bucket 1, which is beneficial to discharge the sewage to the sewage bucket 1.

[0111] In this example, the basic structure of the centrifugal separation cavity 4 includes a body and a top cover 28, the lower end of the body is connected with the second air inlet pipe 5, and the top cover 28 seals the upper end opening of the body, i.e. Figure 6 connecting the body, the second air inlet pipe 5 and the top cover 28 as shown in Figure 4 .

[0112] In this example, the flow guide channel 33 is only arranged in the last stage separation unit, but is not limited to this example.

[0113] The specific structure of the flow guide channel 33 arranged in the last stage separation unit is that: the top cover 28 is further connected with a baffle 29, the baffle 29 and the top cover 28 are provided with the flow guide channel 33, the lower surface of the baffle 29 is a baffle wall, the top cover 28 is provided with a through hole as an air flow channel, the outlet of the air flow channel faces the baffle wall, the baffle wall is provided with the flow guide channel 33, the outlet is communicated with the exhaust port through the flow guide channel 33, the exhaust port is connected with the exhaust pipe 24, the exhaust pipe 24 is provided with the air flow humidity detection sensor 23, that is, the air flow humidity detection sensor 23 is located at the rear side of the flow guide channel 33, the flow guide channel 33 is used for prolonging the flow distance of the air flow, plays a certain buffering effect on the air flow, is beneficial to prevent the sewage from entering, thereby being beneficial to protecting the suction source, in addition, the buffering effect is also beneficial to the air flow humidity detection sensor 23 to play the detection performance, and more effective detection is realized. The flow guide channel 33 includes a flow guide side wall 30, in this example, the flow guide side wall 30 divides the flow guide channel 33 into two channels, and the air flow is discharged through the two air outlets 25.

[0114] The water pump 16, each sensor, the wet mop cleaning part 13 and the like adopt a conventional structure, and details are not repeated here.
