Description

Technical Field

[0001] The present application relates to the technical field of cleaning appliances, and particularly to cleaning equipment, a base, and a cleaning system. Background Art

[0002] With the development of social productive forces, people's living standards have also been improved. On the premise that the material basis is guaranteed, people begin to use various tools to reduce labor and improve the quality of life, and household cleaning equipment emerges as the times require. For example, carpet cleaning equipment, floor washing machines, and so on.

[0003] At present, for water-based household cleaning equipment, wet garbage and solid garbage are both stored in the same recycling cavity. When the adsorption airflow leaves the recycling cavity, it often carries certain solid particles. When passing through the filter element of the recycling cavity, these solid particles will be intercepted by the filter element. Excessive solid particles adsorbed on the filter element will cause blockage of the airflow channel, resulting in suction loss and poor cleaning effect. In addition, if the roller brush on the floor brush of the cleaning equipment is entangled by some dirt, it will also affect the cleaning effect of the cleaning equipment. Summary of the Invention

[0069] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Among some features described in the description, claims and the above-mentioned accompanying drawings of this application, descriptions such as "first" and "second" are used to distinguish different sides, components, parts, modules, devices, etc., and do not represent the order of precedence, nor do they limit that "first" and "second" are of different types. In addition, the embodiments described below are only some embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0070] An embodiment of this application provides a cleaning device. As Figure 1 、 2 shown in Figures 3 and 4, the cleaning device includes: a floor brush 1, a liquid storage bucket 2, a dry recycling bucket 3 and a main motor 4. Among them, a suction nozzle 5 is provided on the floor brush 1. The liquid storage bucket 2 is arranged above the floor brush 1. The dry recycling bucket 3 is communicated with the upper part of the liquid storage bucket 2 and is located behind the liquid storage bucket 2. The main motor 4 is arranged on the floor brush 1 and is located below the dry recycling bucket 3. The main motor 4 is located behind the liquid storage bucket 2 to avoid overlap between the liquid storage bucket 2 and the main motor 4 in the up-down direction, resulting in the need to set a concave space inwards at the bottom of the liquid storage bucket 2 for the main motor 4, so as to occupy the internal space of the liquid storage bucket and form a dead corner area where the liquid cannot be utilized.

[0071] It should be supplemented here that: for the convenience of describing up-down, left-back and front-back, Figure 1 、 Figure 2 and Figure 43 coordinates are marked. As used herein, "up-down" or "vertical" refers to the direction indicated by the Y-axis. The positive direction of the Y-axis (the direction indicated by the arrow) corresponds to up, and the negative direction of the Y-axis corresponds to down. "Front-back" refers to the direction indicated by the X-axis. The positive direction of the X-axis (the direction indicated by the arrow) corresponds to front, and the negative direction of the X-axis corresponds to back. "Horizontal" or "left-right" refers to the direction indicated by the Z-axis. The positive direction of the Z-axis (the direction indicated by the arrow) corresponds to right, and the negative direction of the Z-axis corresponds to left.

[0072] See Figure 5When the main motor 4 operates, the suction airflow generated enters from the suction nozzle 5, sequentially passes through the liquid storage barrel 2 and the dry recovery barrel 3, and then is discharged through the air outlet duct 6 of the main motor 4; the air outlet of the air outlet duct 6 is located at the bottom of the floor brush 1 and faces the area to be cleaned. In the front-rear direction, the air outlet duct 6 is located in front of the dry recovery barrel 3. The dry recovery barrel 3 is communicated with the liquid storage barrel 2 in the front-rear direction, and the dry recovery barrel 3 is communicated with the main motor 4 in the up-down direction.

[0073] Most of the cleaning devices on the market currently have only one barrel for recovering dirty water. Especially for carpet cleaning machines used to clean carpets, they can only recover the dirty water on the ground, and when there are solids such as flying flocs or floating dust, the air inlet will be blocked. In this embodiment, a dry recovery barrel 3 is added to the cleaning device to collect solid dirt and dust flying flocs, reducing the risk of blockage. In addition, in the embodiment of the present application, both the dry recovery barrel 3 and the main motor 4 are arranged at the rear side of the liquid storage barrel 2, and the main motor 4 is located below the dry recovery barrel 3, with a more compact structure and smoother circulation of the suction airflow, which helps to improve the cleaning effect of the cleaning device. The dry recovery barrel 3 is a detachable structure, and the floor brush is provided with a receiving chamber 103 for receiving the dry recovery barrel 3. As Figure 3 shown, the receiving chamber 103 is located above the main motor 4, and the dry recovery barrel 3 can be installed in the receiving chamber 103 or pulled out from the receiving chamber 103 in the front-rear direction. The dry recovery barrel 3 can be fixedly matched with the corresponding groove provided at the bottom of the dry recovery barrel 3 through an elastic locking device (not shown) provided in the receiving chamber 103. After the dry recovery barrel is installed in place, the elastic locking device extends out and locks with the corresponding groove provided on the dry recovery barrel. Of course, the dry recovery barrel 3 and the receiving chamber 103 can also be fixed by interference, and it is not limited thereto.

[0074] See Figure 3 that the receiving chamber 103 can be a groove with openings at the rear side and the upper end as shown in the figure. From Figure 4 the angle shown, the chamber wall of the receiving chamber 103 can be seen.

[0075] In addition, the cleaning device described in this embodiment may further include a heating component 7, as Figure 5 and Figure 7 shown, the heating component 7 is arranged at the air outlet of the air outlet duct 6, and is used to heat the airflow discharged from the air outlet duct 6 to generate a hot airflow blowing towards the cleaning object. The hot airflow can dry the cleaning object (such as a carpet, etc.). From Figure 5As can be seen, with the structure provided in this embodiment, the main motor 4 is located below the dry recovery bin 3. The main motor 4 is placed vertically, which can increase the utilization rate of hot air and contribute to the quick cleaning of cleaning objects (such as carpets, etc.) and the drying of cleaning objects. At the same time, with the motor placed vertically, the air duct travel is optimized and shortened, effectively using the warm air to dry the carpet. Since the main motor 4 is vertically placed, the distance between the main motor 4 and the wall surface accommodating the main motor 4 can also be reduced, making the main motor 4 occupy a small area in the horizontal direction and making the overall arrangement of the main motor 4, the dry recovery bin 3, and the liquid storage bucket 2 more compact. As Figure 5 and Figure 7 shown, the floor brush 1 is also provided with a roller brush 8 and rollers 9. From the front end to the rear end of the floor brush 1, the suction nozzle 5, the roller brush 8, the heating assembly 7, and the rollers 9 are sequentially arranged. Such an arrangement facilitates the drying of the roller brush 8 during self-cleaning of the cleaning device; the content related to self-cleaning will be described in detail below, and reference can be made to the content below. From top to bottom, the dry recovery bin 3, the main motor 4, and the rollers 9 are arranged in sequence from top to bottom.

[0076] Figure 6 shows Figure 2 the internal structure of the floor brush 1 after removing the liquid storage bucket 2, the upper cover 10 of the floor brush, and the lower cover 11 of the suction nozzle from the whole cleaning device shown. As can be seen from Figure 6 and Figure 10 , the floor brush 1 is also provided with: a roller brush motor 12, a pump 13, rollers 9, a water spraying device 14 (as Figure 12 shown), etc. Among them, the main motor 4 can be located between the two rollers 9. The cleaning device further includes a body 15, and the body 15 is connected to the handle 31 through a connecting rod 16. After the liquid storage bucket 2 is removed, as can be seen from Figure 6 , the floor brush 1 is also provided with an intermediate member 127. The intermediate member 127 is located between the liquid storage bucket 2 and the dry recovery bin 3. The intermediate member 127 is provided with a first communication port 68, and the receiving chamber 103 is provided with an interface corresponding to the first communication port 68. A connecting member passes through the first communication port 68 and the interface. The connecting member is made of soft rubber and has a channel connecting the liquid storage bucket 2 and the dry recovery bin 3. The rear end of the connecting member is docked and communicated with the inlet of the dry recovery bin 3, and its front end is communicated with the corresponding interface provided on the liquid storage bucket 2. The dry recovery bin 3 is communicated with the liquid storage bucket 2 through the connecting member. Figure 4 shows the working state of the cleaning device. The user holds the handle 31 and tilts the body 15 and the connecting rod 16 backward, and pushes the floor brush 1 forward through the handle 31. The liquid storage bucket 2, the dry recovery bin 3, and the main motor 4 are on the floor brush 1 and move forward with the floor brush 1.

[0077] The body 15 has two connecting arms 104, which are connected to each other above to form an inverted U shape. In the unused state, the dry recycling bin 3 is located within the space formed by the two connecting arms 104. When viewed from the front to the back, the liquid storage bin 2 obscures the dry recycling bin 3. The two connecting arms 104 are located on both sides of the dry recycling bin. The tops of the two connecting arms are connected to form an inverted U-shaped space. When viewed from the back to the front, the dry recycling bin 3 is located below the U-shaped top of the inverted U-shaped structure and between the two connecting arms 104.

[0078] See Figure 8 As shown, the floor brush 1 is also provided with two mounting holes 105, which are located on both sides of the main motor 4. The end portions of the two connecting arms 104 of the body 15 are respectively installed in the two corresponding mounting holes 105, and the two connecting arms 104 can rotate relative to the floor brush 1. As Figures 1 to 3 , the body 15 is in an upright state; as Figure 4 , after the body 15 rotates and tilts backward relative to the floor brush, the user can hold the handle 31 on the body 15 to operate the cleaning device.

[0079] See Figure 7 As shown, an air distribution plate, namely a perforated plate 17, is provided in the air outlet duct 6. There are two perforated plates 17 in the air outlet duct 6. One perforated plate 17 is arranged in the air outlet duct 6 near the main motor 4, and the other is arranged near the heating component 7. The perforated plate 17 arranged near the main motor 4 is vertically arranged in the air outlet duct 6, and the other perforated plate 17 arranged near the air outlet is horizontally arranged. The two perforated plates 17 are arranged perpendicular to each other. The air flow entering the air outlet duct 6 is dispersed after passing through the holes on the perforated plate 17. Or rather, the air volume entering and leaving is adjusted through a plurality of through holes to realize the adjustment of the air in the duct, and then flows to the heating component 7. The air flow coming out of the main motor 4 is a spiral air flow, which will flow along one side of the air outlet channel and cannot be evenly diffused in the air outlet channel. Through this perforated plate, the spiral air flow can be dispersed to form a uniform air flow, making the air flow blowing to the heating component 7 more uniform, and the hot air flow passing through the heating component 7 and dissipating from the air outlet more uniform, so that the area to be dried under the floor brush is evenly dried, which helps to improve the drying efficiency.

[0080] Furthermore, the main motor 4 is a brushed motor. A cooling fan 18 is also provided inside the main motor 4, and an impeller is arranged outside. As Figure 7 shown, the main motor 4 includes two cavities, namely an inner cavity 22 and an outer cavity 23. A power component 19 is provided in the inner cavity 22; a cold air suction inlet 20 is provided at the bottom of the inner cavity 22. As Figure 3As shown in the figure, a heat dissipation air suction duct 106 is provided between the rear side of the floor brush 1 and the two rollers 9. The heat dissipation air suction duct 106 is communicated with the cold air suction port 20. In addition to the above heat dissipation air suction duct 106, a heat dissipation air suction duct is also provided on each of the two sides at the front end of the floor brush 1. A heat dissipation fan 18 is provided at the top of the inner cavity 22. There is a heat dissipation channel between the inner cavity 22 and the outer cavity 23; the exhaust port of the heat dissipation channel is located at the rear side of the cold air suction port 20. As Figure 7 shown, the heat dissipation air outlet can be located at the bottom of the floor brush 1, and the air flow discharged from the exhaust port of the heat dissipation channel is discharged through the heat dissipation air outlet 107 at the bottom. The power shaft of the power assembly 19 passes through the top cavity wall of the inner cavity 22 and the top cavity wall of the outer cavity 23. An impeller 21 is provided at the end of the power shaft passing through. The power assembly 19 works to output rotational power to drive the impeller 21 to rotate, generating a suction air flow. The heat dissipation fan 18 works to suck external air flow from the cold air suction port 20 at the bottom to the top of the inner cavity 22, then enters the heat dissipation channel between the inner and outer cavities 22 and 23 and descends to the bottom, and is discharged from the heat dissipation air outlet 107 provided at the bottom of the floor brush to dissipate heat from the main motor 4. The main motor 4 is housed in the motor cavity, and a channel communicating with the air outlet duct 6 is formed between the main motor 4 and the inner wall of the motor cavity, and this channel is separated from the heat dissipation channel between the inner and outer cavities 22 and 23 and is not communicated with each other.

[0081] The cleaning device described in this embodiment further includes an absolute pressure sensor 24 and a control device. Among them, the control device is not clearly shown in the drawings. The control device can be provided on the floor brush 1 or the body 15. This embodiment does not make specific limitations on this. Refer to Figure 5 and Figure 7 , the absolute pressure sensor 24 is provided between the dry recovery bucket 3 and the main motor 4. The control device can be provided on the floor brush 1 and is electrically connected to the absolute pressure sensor 24; the control device is used to obtain the first data collected by the absolute pressure sensor 24 when the cleaning device is powered on but the main motor 4 has not been started; determine the blockage determination reference value corresponding to the first data; after the main motor 4 is started, if the second data collected by the absolute pressure sensor 24 is lower than or equal to the blockage determination reference value, it is determined that the air flow pipeline is blocked. The dry recovery bucket 3, the liquid storage bucket 2 and the suction nozzle 5 in the air flow pipeline path are detachable structures. When a blockage occurs, the user can detach the above three for troubleshooting and cleaning to eliminate the fault.

[0082] Specifically, as Figure 5 shown, the suction air flow port of the main motor 4 (i.e., the port corresponding to the impeller 21) is communicated with the air outlet of the dry recovery bucket 3. A sealing device can be provided between the main motor 4 and the dry recovery bucket 3. More specifically, Figure 5In the shown structure, the bottom of the dry recycling bin 3 is an inclined plane, with the side closer to the liquid storage bin 2 (i.e., the side facing the front end of the floor brush 1) being higher and the side farther from the liquid storage bin 2 (i.e., the side facing the rear end of the floor brush 1) being lower. Above the main motor 4, there is an inclined plane adapted to the said inclined plane, and the sealing device is arranged at the connection of the two inclined planes. Due to the inclined plane above the main motor 4, there is a space, and the absolute pressure sensor 24 can be arranged in this space. When the user installs the dry recycling bin 3, the inclined plane can also play a guiding role, guiding the user to push the dry recycling bin 3 into the installation position. At the installation position, the dry recycling bin 3 is hermetically connected to the main motor 4 below and communicated with the liquid storage bin 2.

[0083] It can be seen that adding the absolute pressure sensor 24 in this embodiment can detect the state of the suction air flow duct in real time, intelligently identify blockages, and improve the user experience. When there is a blockage during cleaning in the suction air flow duct, it will cause the cleaning device to be unable to normally suck in dirt. From the perspective of the user experience, the user will feel that the cleaning ability of the cleaning device is weak.

[0084] In addition, due to the different altitudes of the regions where the users are located, if a determination reference value is used to compare with the data sensed by the absolute pressure sensor 24 to determine whether there is a blockage, false alarms will occur, which will also affect the user's use. For example, one user is in a low-altitude or conventional-altitude area, such as Beijing, and another user is in a high-altitude area, such as Lhasa. The altitude of the Beijing Plain is more than 20 meters; the altitude of Lhasa is 3650 meters. If the cleaning device uses the determination reference value set for the altitude of Beijing. Then, when the user in Lhasa uses this cleaning device, it will report a blockage, and the user cannot use the device normally. To solve this problem, in the embodiment of the present application, when the cleaning device is powered on but the main motor 4 is not started, the absolute pressure sensor 24 is allowed to collect once to obtain the first data corresponding to the current air pressure environment; and based on this first data, the corresponding blockage determination reference value is determined.

[0085] Among them, "determining the corresponding blockage determination reference value based on this first data" can be specifically: obtaining the corresponding relationship table between the threshold data and the blockage determination reference value, and based on this relationship table, determining the blockage determination reference value corresponding to the first data.

[0086] The above relationship table can be obtained by testing the readings of the absolute pressure sensor 24 corresponding to blockages under the air pressure of 60Kpa - 102Kpa.

[0087] In an implementable embodiment, the process of the control device determining whether there is a blockage may include the following steps:

[0088] S11. When the cleaning device is powered on but the main motor 4 is not started, obtain the first data collected by the absolute pressure sensor 24.

[0089] Among them, this first data is the atmospheric pressure value of the current altitude.

[0090] S12. Determine the blockage determination reference value corresponding to the first data.

[0091] After the main motor 4 starts, obtain the second data collected by the absolute pressure sensor 24, and compare the second data with the blockage determination reference value.

[0092] S14. If the second data is lower than or equal to the blockage determination reference value and lasts for a set duration, it is determined that there is a blockage.

[0093] It should be noted here that "lasts" means that the absolute pressure sensor 24 collects the second data at a set sampling frequency, and all the second data collected within the set duration is lower than or equal to the blockage determination reference value. The set duration here can be 30 ms, 1 s, etc. The specific value of this embodiment is not limited, and it can be determined based on the actual product design requirements.

[0094] S15. If the second data is lower than or equal to the blockage determination reference value, but the continuous duration is less than the set duration, return to step S13 and continue to obtain the second data collected by the absolute pressure sensor 24.

[0095] S16. If the second data is greater than the blockage determination reference value, return to step S13 and continue to obtain the second data collected by the absolute pressure sensor 24.

[0096] In this embodiment, by using the absolute pressure sensor 24 in combination with the above determination logic, an accurate determination can be made on whether the air flow channel of the cleaning device is blocked. When the cleaning device is cleaning and drying, it will inhale some light dirt, hair and other substances that are easy to block the air flow channel, which will cause the loss of the overall machine characteristics, and then lead to a decrease in the water recovery rate, an increase in the drying time, and a deterioration of the cleaning effect. However, the user cannot intuitively feel the occurrence of this bad phenomenon, which greatly affects the use experience. The solution provided in this embodiment can not only make an accurate judgment and reminder when the blockage occurs, but also take into account the conditions of the machine under different altitudes and different atmospheric pressures, and intelligently remind the user to clean (such as dumping the garbage in the dry recycling bin 3, the sewage inlet pipe 26, the intermediate pipe 27, the suction nozzle channel 25, etc.), ensuring that the machine is in the best performance when in use and guaranteeing the user's use experience. Of course, in addition to the reminder, the cleaning device can also take measures such as stopping the machine after determining the blockage. This embodiment does not limit this.

[0097] Further, such as Figure 5 and 7As shown, a suction nozzle channel 25 is further provided on the floor brush 1. One end of the suction nozzle channel 25 communicates with the suction nozzle 5, and the other end communicates with the bottom inlet of the sewage inlet pipe 26; the sewage inlet pipe 26 is vertically arranged, the top outlet of the sewage inlet pipe 26 communicates with the inlet of the liquid storage barrel 2, and the inlet at the bottom of the sewage inlet pipe 26 is exposed outside the liquid storage barrel 2, and the sewage inlet pipe 26 is not arranged inside the fuselage. In this embodiment, the sewage inlet pipe 26 is arranged outside the liquid storage barrel 2 and is fixedly arranged with the liquid storage barrel 2, and the bottom inlet of the sewage inlet pipe 26 is higher than the bottom of the liquid storage barrel 2; however, in other alternative ways, the sewage inlet pipe 26 can also be integrally arranged with the liquid storage barrel, or arranged inside the liquid storage barrel 2, or the sewage inlet pipe is fixedly installed on the fuselage or integrally arranged with the fuselage.

[0098] See Figure 26 、 Figure 27 and 28 As shown, the liquid storage barrel 2 further includes a barrel cover 65 provided at the open top of the sewage storage space. The barrel cover 65 is provided with a bent channel communicating with the top outlet of the sewage inlet pipe 26. Among them, Figure 26 and Figure 28 In the dotted line circles in, a partial section treatment is adopted, and a cut as shown in the figure is formed at the bent channel. Specifically, as Figure 27 and Figure 28 shown, the fluid entering from the inlet end 651 of the bent channel enters the liquid storage barrel 2 along the Figure 28 path shown. The top outlet of the sewage inlet pipe 26 is arranged forward, while the bent channel of the barrel cover 65 is provided with an inlet end 651 (i.e., the inlet of the bent channel) communicating with the outlet of the sewage inlet pipe 26, and the inlet end 651 is arranged backward, and the outlet end of the barrel cover 65 is arranged toward the front wall of the liquid storage barrel 2 to prevent the splashing liquid from being sucked by the main motor 4. The inlet end and the outlet end of the barrel cover 65 are connected by a bent channel inside. Refer to Figure 28 the barrel cover 65 in the partial sectional view shown in. As Figure 26 and 28 shown, the barrel cover 65 includes: a cover body 652 and a bent channel 654. The upper surface of the cover body 652 is provided with a holding part 653, and the lower surface of the cover body 652 is provided with a downward extending bent channel 654. The bent channel 654 is offset and arranged on the lower surface of the cover body 652 to communicate with the outlet of the sewage inlet pipe located on one side of the liquid storage barrel. Specifically, as Figure 26 and 28, the bent channel 654 includes a transverse channel wall 6541 extending from the rear side to the front side and a vertical channel wall 6542 extending downward at the front side. A bottom plate 6543 is provided at the bottom of the vertical channel wall 6542. An outlet 6544 is provided on the bottom plate 6543, and the outlet 6544 faces the front side (i.e., the side away from the main motor 4 and the dry recovery barrel 3). Or rather, the outlet 6544 of the bent channel faces the front wall of the liquid storage barrel. While ensuring the drainage effect, it avoids affecting the flow of the fluid. Combining Figure 28 it can be known that the fluid entering through the inlet end flows along the bent channel, first flowing horizontally from the rear side to the front side, and then flowing vertically downward to enter the liquid storage barrel. In this embodiment, an opening is provided on the front side wall of the vertical channel wall as the outlet. The stepped front side wall can play a drainage role while ensuring the fluid flux and will not affect the flow of the fluid. The bottom plate can play a role in draining the fluid forward. Without the bottom plate, the fluid will flow directly downward; here, the bottom plate is designed to continue draining the fluid forward after the transverse channel wall. Refer to Figure 24 As shown, a partition member 121 is provided in the liquid storage barrel, dividing the liquid storage barrel into two spaces, namely the upper sewage storage space 59 and the lower clean water storage space 60. The partition member is obliquely arranged, with the front end lower and the rear end higher. There is clean water in the clean water storage space 60, making the partition member 121 in a Figure 24 convex state as shown. If the bottom plate is not provided at the bottom of the vertical channel wall, part of the fluid will enter the rear area of the convex partition member 121, and part of the liquid will enter the front area of the convex partition member 121. In this way, it is very easy to misreport that the sewage storage space 59 is full. Therefore, in this embodiment, a bottom plate is provided at the bottom of the vertical channel wall to continue draining the fluid forward.

[0099] More specifically, as shown in Figure 5 , Figure 6 and Figure 10 , an intermediate pipe 27 as shown in Figure 5 is also connected between the suction nozzle channel 25 and the sewage inlet pipe 26. The intermediate pipe 27 is obliquely arranged in the floor brush 1; at the angle shown in Figure 5 , the intermediate pipe 27 is a concave curve. The design of the concave curve is to leave a position for the liquid storage barrel slot 28, making the structure of the floor brush 1 more compact and small. At the same time, it can also reduce the avoidance space required to be correspondingly set at the bottom of the liquid storage barrel 2, avoiding reducing the overall available volume of the liquid storage barrel 2. Figure 8 shows a schematic diagram of the floor brush 1 after installing the floor brush upper cover 10. The floor brush upper cover 10 is provided with a liquid storage barrel slot 28 and a raised avoidance part for avoiding the sewage inlet pipe 26. Refer to Figure 6 As shown, the intermediate pipe 27 extends backward to the rear wall of the liquid storage barrel and forms an interface exposed outside the floor brush. As shown in Figure 5 , the inlet of the sewage inlet pipe 26 is communicated with the interface of the intermediate pipe 27.

[0100] From Figure 10 It can be seen that in the horizontal direction perpendicular to the vertical direction, that is, in the horizontal direction formed by the X-axis and the Z-axis, one end of the connecting suction nozzle channel 25 of the middle pipe 27 is located in the middle of the front end of the floor brush 1; while the middle pipe 27 extends from this middle position to the rear end of the floor brush 1, it gradually deviates to one side of the floor brush 1 to communicate with the dirt inlet pipe 26.

[0101] As shown in FIGS. 8 and 9, the suction nozzle top cover 113 and the suction nozzle bottom cover 11 are buckled to form the suction nozzle channel 25. The suction nozzle channel 25 is detachably fixed to the front end of the floor brush 1. The suction nozzle top cover 113 is pivotally fixed to the suction nozzle bottom cover 11 and is locked and fixed thereto. The suction nozzle bottom cover 11 is detachably arranged on the floor brush 1. The suction nozzle bottom cover 11 extends upward from the bottom of the front end of the floor brush 1 to the top of the floor brush 1. As Figure 8 shown in the example, the suction nozzle bottom cover 11 is of an arc-shaped structure. Suction nozzle unlocking mechanisms 108 are provided on both sides of the top of the floor brush 1 (i.e., the left and right sides of the floor brush). In one implementation, the suction nozzle unlocking mechanism 108 can be a pressing mechanism, and a locking portion is provided on the pressing mechanism. Correspondingly, as Figure 9 shown, a locking claw 112 is provided at the corresponding position of the suction nozzle bottom cover 11. One side of the locking claw 112 corresponding to the pressing mechanism is a slope. The end of the locking claw 112 has a locking hook. The locking claw 112 is inserted into the locking portion and is locked in the locking portion of the pressing mechanism through the locking hook. When disassembling, the user presses the pressing mechanisms on both sides of the floor brush. The locking portion moves inward under the pressing force and disengages from the locking claw 112 below the suction nozzle bottom cover 11 to achieve unlocking. At the same time, the pressing mechanism moves inward and contacts the slope on the locking claw 112 to lift the locking claw. That is, after unlocking, the suction nozzle provided with the locking claw pops out a part outward. In the state where both sides of the unlocking mechanism are unlocked, the suction nozzle can be detached from the floor brush as a whole, which is convenient for the user to clean the suction nozzle separately.

[0102] See Figure 7 and 8 shown, the roller brush cavity cover plate 110 is located inside the suction nozzle channel 25. The roller brush cavity cover plate 110 can be a transparent cover plate so that the user can view the operation of the roller brush through the transparent cover plate. At the same time, the suction nozzle top cover 113 and the suction nozzle bottom cover 11 are also transparent parts. A claw fixing mechanism 115 is provided at the position of the roller brush cavity cover plate 110 corresponding to the lower part of the floor brush 1 (i.e., the position near the bottom of the front end of the floor brush). See Figure 9 , a fixing claw 111 is provided at the corresponding position of the suction nozzle bottom cover 11. When installing the suction nozzle bottom cover 11, the fixing claw 111 can be fixed at the claw fixing mechanism 115 first, and then the suction nozzle bottom cover 11 is rotated inward and pressed down to lock the locking claw 112 into the locking portion, and the installation of the suction nozzle bottom cover can be completed.

[0103] Furthermore, as Figure 8As shown, a suction port 1061 is provided on the floor brush 1, and this suction port 1061 is communicated with the intermediate pipe 27 mentioned above. As Figure 2 As shown, a nozzle top cover 113 can also be provided on the nozzle lower cover 11. A through hole is provided at the position of the suction port 1061 on the corresponding floor brush of the nozzle lower cover 11. The suction port 1061 is communicated with the nozzle channel 25 between the nozzle top cover 113 and the nozzle lower cover 11 through the through hole. The nozzle top cover 113 is fixedly connected to the nozzle lower cover 11 through a top cover unlocking mechanism 109, and the bottoms of both are pivotally connected. When the nozzle channel 25 is blocked or needs to be cleaned, the top cover unlocking mechanism 109 can be operated to flip and open the nozzle top cover 113 from the nozzle lower cover 11, so as to facilitate cleaning of the nozzle channel 25. When the user needs to externally connect an accessory brush, opening the nozzle top cover 113 can connect the accessory brush with the suction port 1061.

[0104] At least one of the pipe walls of the nozzle channel 25, the intermediate pipe 27, and the dirt inlet pipe 26 is provided with a first sensor for detecting the degree of dirt. A reflection area 29 is provided at the pipe wall corresponding to the position of the first sensor. The detection signal emitted by the first sensor into the pipe reaches the reflection area 29 and is then reflected back to the first sensor by the reflection area 29. Specifically, the first sensor includes a transmitting end and a receiving end. The transmitting end is used to emit a detection signal, and the receiving end is used to receive the reflected detection signal. Adding the reflection area 29 is equivalent to increasing the detection surface and improving the detection accuracy.

[0105] At least one of the pipe walls of the nozzle channel 25, the intermediate pipe 27, and the dirt inlet pipe 26 is provided with the first sensor. The pipe is a transparent pipe.

[0106] For example, the first sensor can be an RGB sensor, that is, a color sensor. The reflection area 29 can be realized by coating a reflection material on a certain area of the pipe wall surface of the dirt inlet pipe 26, such as electroplating an aluminum layer on the pipe wall surface to form a reflection area. The RGB sensor includes a transmitting end and a receiving end. The transmitting end emits an optical signal, and the optical signal refracted by the liquid in the pipe passes through the reflection area 29 and then returns to the receiving end of the RGB sensor along the original path. After adding the reflection area 29, it is equivalent to point-to-plane detection, improving the detection effect. The reflection area 29 can also be realized by installing a reflection material on the wall surface, such as an aluminum foil patch, a reflection mirror, or other reflection materials.

[0107] See Figure 10 In the example shown, the position indicated by the reference numeral in the figure is the reflection area 29. Opposite to the reflection area 29, a first sensor is provided on the pipe wall of the intermediate pipe 27.

[0108] In this embodiment, by adding a first sensor and a reflection area 29 in a pipeline (such as a suction nozzle channel, the intermediate pipeline 27, or the sewage inlet pipe 26), it is possible to intelligently identify the dirtiness of the cleaning object by detecting the dirtiness of the inhaled solid waste and liquid; and then it is convenient for the control device of the cleaning equipment to adjust the working parameters of the cleaning equipment according to the dirtiness. Among them, the working parameters may include but are not limited to: the rotation speed of the rotary brush 8, the water spraying amount of the water spraying device 14, and so on.

[0109] When the cleaning equipment is in use, the user can hold the handle 31 and push and pull the floor brush 1 to move on the cleaning object, so as to clean the cleaning object. However, there are some cleaning equipment, such as the equipment with a liquid storage bucket 2, more specifically, a floor washer, a carpet cleaner, etc., with a large body weight. Especially for a carpet cleaner, it is more laborious for the user to push and pull. When the carpet cleaner is pushed on the carpet, the pile of the carpet has a large resistance to the floor brush 1, making the push and pull even more laborious. Therefore, the embodiment of the present application also adds an assisting system to the cleaning equipment to provide assistance for the rollers 9 on the floor brush 1, making it easier for the user to use. The assisting system includes an assisting driving device arranged on the floor brush 1 and a pre-identifying device arranged at the handle 31 and the connecting rod 16. The pre-identifying device is used to identify the user's usage intention. The control device is electrically connected to the pre-identifying device, and the control device controls the assisting driving device to output power according to the user's usage intention identified by the pre-identifying device, so as to drive the rollers 9 to act (such as moving forward, backward, turning, etc.). But not limited to: an assisting motor 30, a code disk assembly, etc. The floor brush 1 has two rollers 9. The two rollers 9 are respectively driven by two different assisting driving devices. The power end of the assisting motor 30 is connected to the axle of the roller 9 for driving the roller 9 to roll. In specific implementation, if a speed reducer assembly needs to be equipped for the selection of the assisting motor 30, the assisting motor 30 can be connected to the roller 9 through the speed reducer assembly. The code disk assembly is arranged on the roller 9 for detecting the rolling parameters of the roller 9 (such as rolling speed, rolling direction, etc.). The code disk assembly sends the detected rolling parameters to the control device, and the control device controls the working of the assisting motor 30 based on the rolling parameters to ensure the assisting effect.

[0110] The pre-identifying device is an assisting sensor 99 arranged at the connection of the handle 31 and the connecting rod 16, which identifies the user's usage intention by sensing the pushing and pulling force of the user using the cleaning equipment.

[0111] That is, such as Figure 13 and 14In the illustrated example, the cleaning device described in this embodiment may further include a handle 31, a connecting rod 16, a body 15, a control device, and an assisting motor 30. One end of the body 15 is rotatably connected to the floor brush 1, and the other end is connected to the connecting rod 16. The handle 31 is disposed at the end of the connecting rod 16. A force assisting sensor 99 is provided at the connection between the handle 31 and the connecting rod 16 for sensing the pushing and pulling force applied by the user to the cleaning device. The assisting motor 30 is connected to a roller 9 on the floor brush 1. The control device is disposed on the floor brush 1 or the body 15 and is electrically connected to the force assisting sensor 99 and the assisting motor 30. Among them, the control device is configured to control the operation of the assisting motor 30 according to the sensed pushing and pulling force to drive the roller 9 to act to provide assistance. Figure 14 The code disk assembly and the reduction gearbox assembly corresponding structures are not shown in the figure. The force assisting sensor 99 senses the pushing and pulling force applied by the user to the cleaning device. The control device controls the assisting motor 30 to start working according to the pushing and pulling force sensed by the force assisting sensor. By setting a certain threshold value, the mis-start of the assisting system can be prevented.

[0112] Due to different conditions in different cleaning areas, the resistance to the cleaning device is different. A single assisting gear is difficult to adapt to the cleaning areas under different resistance conditions. Therefore, the cleaning device may further include an assisting gear switch 32 to adjust the assisting force required for the cleaning areas under different resistance conditions; the assisting gear switch 32 is disposed on the body 15 and / or the handle 31. Figure 14The illustrated example shows that the power assist gear switch 32 is provided on the body 15. The power assist gear switch 32 has multiple gears, and different gears correspond to different power assist magnitudes; the control device is electrically connected to the power assist gear switch 32. By setting the power assist gear switch 32 here, the user can select the power assist magnitude through this power assist gear switch 32. For example, the power assist gear switch 32 has three gears to choose from. The first gear has a large power assist, the second gear has a moderate power assist, and the third gear has a small power assist. What the power assist gear switch 32 adjusts is the different required arrival times for the same acceleration value. The time required to reach the same acceleration value in the first gear is less than that required in the second and third gears, so as to adapt to the resistance of different cleaning areas and maintain a sense of follow-up with the user. Especially for carpets, long-haired and short-haired carpets have different resistances to the same cleaning device, and different carpet materials with different hardness levels will also cause different resistances; even the roughness of the carpet fluff will also affect the resistance. The user can select the gear according to their own usage habits. For example, when the current user wants to use the cleaning device to clean a long-haired carpet, the user can select the first gear; if the current user uses the cleaning device to clean a short-haired carpet, the user can select the second or third gear, and at the same time, it can also prevent the roller from idling and slipping in place due to excessive power assist when cleaning the short-haired carpet, and prevent the pushing and pulling from being laborious due to too little power assist on the long-haired carpet. At the same time, the gear switch 32 can also be used to identify long-haired and short-haired carpets, so that the cleaning device adopts a cleaning mode corresponding to the gear, such as adjusting the power of the heating component to adapt to long-haired and short-haired carpets. For example, the power of the heating component in the first gear is greater than that in the second gear, and the power in the second gear is greater than that in the third gear.

[0113] The control device controls the operation of the power assist motor 30 based on the gear where the power assist gear switch 32 is located and the pushing and pulling force sensed by the power assist sensor, so as to drive the roller 9 to act to provide power assist.

[0114] In the first feasible embodiment, as Figure 15 、 16 、17 and 18 show, the power assist sensor 99 is a strain sensing device that can deform along the length direction of the connecting rod 16 and sense the pushing and pulling force through the amount of deformation. As Figure 18 shows, the strain sensing device includes a strain block 33 and a strain gauge 34, and the strain gauge 34 is provided on the strain block 33. One end of the strain block 33 is connected to the handle 31, and the other end is connected to the connecting rod 16. When the strain block 33 deforms due to the pushing and pulling force of the handle 31, the strain gauge 34 generates a sensed electrical signal and sends it to the control device, so that the control device controls the operation of the power assist motor 30 according to the received sensed electrical signal.

[0115] For example, as Figure 18As shown in the figure, the strain block 33 is a rectangular parallelepiped; along the length direction, the strain block 33 is provided with a first deformation groove 35, a through hole 37 and a second deformation groove 36 in sequence. Along the width direction, the notches of the first deformation groove 35 and the second deformation groove 36 face each other. When the strain block 33 is subjected to a pulling force in the length direction, the notch gap 76 between the first deformation groove 35 and the second deformation groove 36 becomes larger; when the strain block 33 is subjected to a pushing force in the length direction, the notch gap 76 between the first deformation groove 35 and the second deformation groove 36 becomes smaller.

[0116] In a specific embodiment, Figure 18 As shown, the first deformation groove 35 includes: a first oblong hole extending along the width direction, and a first slit 38 penetrating from a straight side of the first oblong hole to the first side of the strain block 33; the strain gauge 34 is provided at the other straight side of the first oblong hole. The second deformation notch 89 includes: a second oblong hole extending along the width direction, and a second slit 39 penetrating from a straight side of the second oblong hole to the second side of the strain block 33; the strain gauge 34 is provided at the other straight side of the second oblong hole. In the width direction, the first side and the second side of the strain block 33 are opposite.

[0117] See also Figure 17 In the example shown, the strain sensing device is arranged in a bracket 40. The upper part of the strain block 33 of the strain sensing device is connected to the bracket 40. The lower part of the strain block 33 is connected to the fixed block 41 outside the bracket 40. The top and bottom of the strain block 33 contained in the bracket 40 are respectively connected to the bracket 40 and the fixed block 41 through a connector to form an assembly module. After the three are assembled into a module, they are assembled with the handle and the connecting rod to form a modular installation, which reduces the difficulty of assembly and also reduces the installation error, avoiding the error causing the strain block 33 to be subjected to excess force and produce false alarms or inaccurate force measurement. The bracket 40 and the fixed block 41 are embedded in the straight rod section 42 of the handle lining and the connecting rod 16. The bracket 40 is connected to the straight rod section 42 of the handle lining, and the fixed block 41 is connected to the connecting rod 16. Among them, the handle 31 includes a gripping portion and a tubular straight rod section 42 extending downward from the gripping portion, and the straight rod section 42 is inserted into the connecting rod 16 and connected through an external connector.

[0118] The strain sensing device, the bracket 40 and the fixing block 41 can be installed as an integral module.

[0119] In another feasible technical solution, as Figure 19As shown, the pre-identification device includes: a strain gauge 34, a dial block 44, and a reset soft rubber 45. Along the axial direction of the connecting rod 16, the strain gauge 34 and the reset soft rubber 45 are sequentially arranged on the first mounting plate 46. The strain gauge 34 and the reset soft rubber 45 are spaced apart by a certain distance. Both the strain gauge 34 and the reset soft rubber 45 extend along a direction perpendicular to the axial direction of the connecting rod 16. The first mounting plate 46 is fixed on the straight rod section 42 of the handle inner lining. Along the axial direction of the connecting rod 16, the dial block 44 and a reset groove are sequentially arranged on the second mounting plate 47. The second mounting plate 47 is fixed on the connecting rod 16. The dial block 44 has a groove, and the end of the strain gauge 34 is inserted into the groove. The reset soft rubber 45 is inserted into the reset groove.

[0120] When the user pulls the handle 31, the straight rod section 42 of the handle inner lining has an action of detaching from the connecting rod 16, causing the dial block 44 to act and deflect the strain gauge 34 downward in the Figure 19 shown perspective. The reset soft rubber 45 will also deform accordingly. When the pulling force does not exist, the restoring force of the reset soft rubber 45 causes the dial block 44 to return to its original position, and the strain gauge 34 returns to its original state. When the user pushes the handle 31, the straight rod section 42 of the handle inner lining has an action of entering the connecting rod 16, causing the dial block 44 to act and deflect the strain gauge 34 upward in the Figure 19 shown perspective. Similarly, the reset soft rubber 45 will also deform accordingly. When the pushing force does not exist, the restoring force of the reset soft rubber 45 causes the dial block 44 to return to its original position, and the strain gauge 34 returns to its original state.

[0121] In the embodiment of the present application, by adding a pre-identification device and an assist driving device, the force used by the user during pushing and pulling can be reduced; at the same time, during the assist process, the pre-identification device can adjust the feel of the assist in real time according to the user's usage habits, giving the user the most satisfactory assist effect. At the same time, by arranging the pre-identification device at the connection between the handle and the connecting rod, it is possible to avoid occupying the limited space of the handle and also avoid damage or difficulty in recognizing the magnitude of the force applied by the user directly to the strain device on the handle when the body is too heavy.

[0122] In a feasible technical solution, the handle 31 has multiple sides, and the multiple sides are connected end to end, as in Figure 20 the illustrated example. The multiple sides at least include a first side 48, a second side 49, and a third side 50. The first side 48 is vertical and forward, and is a forwardly convex arc. The second side 49 extends backward and upward from the top end of the first side 48; the third side 50 extends backward from the bottom end of the first side 48. The straight rod section 42 of the handle inner lining is connected to the side of the third side 50 opposite to the second side 49. An interaction device is provided on the front side of the first side 48. Here, "front" is referenced with the floor brush 1. Figure 1Shows the installation method of the handle 31 in the whole machine. The first side 48 of the handle 31 faces forward and protrudes forward in an arc.

[0123] See Figure 20 , the second side 49 extends backward and upward from the top of the first side 48. It can be understood that the second side 49 is an inclined hypotenuse that is backward and upward.

[0124] Furthermore, as Figure 20 shown in the example, the multiple sides may further include a fourth side 51. The two ends of the fourth side 51 are respectively connected to the end of the second side 49 and the end of the third side 50.

[0125] Furthermore, see Figure 20 the first auxiliary line a and the second auxiliary line b shown; the first auxiliary line a is the tangent of a point on the arc; the second auxiliary line b is the central axis of the two sides; the included angle c between the first auxiliary line a and the second auxiliary line b is 120 - 160 degrees. For example, the first auxiliary line a can be the tangent of a point on the midpoint of the arc.

[0126] Figure 21 Shows the exploded schematic diagram of the handle 31 structure. As Figure 21 shown, the handle 31 includes a handle inner lining, a handle upper cover 54 and a handle lower cover 55. The handle inner lining includes a main body part 43 corresponding to the above multiple sides and a straight rod section 42 extending downward from the third side 50. The main body part 43 is a groove structure and can be used to accommodate some electrical components, such as a button assembly 52, a screen assembly 53, etc.

[0127] Among them, the button assembly 52 as Figure 2 shown may include: a working mode switching button 521, a power on / off button 522, a drying button 523, etc.

[0128] One way is: the handle upper cover 54 and the handle lower cover 55 are respectively buckled from above and below the main body part 43 to enclose the main body part 43 and the electrical components installed on the main body part 43 inside. Another way is: the handle upper cover 54 and the handle lower cover 55 are respectively buckled from above and below the main body part 43 to enclose the second side 49, the third side 50 and the fourth side 51 of the main body part 43 and the electrical components installed on the corresponding sides inside; a screen assembly 53 adapted to the first side 48 is provided on the first side 48. For example, Figure 21In the illustrated example, a key assembly 52 is provided at the second side 49. The screen assembly 53 may include, but is not limited to, a screen element 56, a screen bracket 57, and a screen cover plate 58. The screen element 56 is disposed on the screen bracket 57, and the screen bracket 57 is fixed at the first side 48 of the main body portion 43, and the screen cover plate 58 is provided at the outermost side. Alternatively, the screen bracket 57 and the screen cover plate 58 are integrally formed by secondary injection molding, and the screen element 56 and the integral structure can be fixed by a fixing structure (such as a snap structure, etc.). The screen assembly 53 is further fixed to the upper handle cover 54 and the lower handle cover 55 by a connecting member (such as a screw, etc.).

[0129] After considering the user experience, the above-mentioned handle 31 structure is adopted in this embodiment. When the handle 31 is in use, it can ensure that the screen display content can be observed from multiple angles. And when the machine is on the base or in an upright state during the self-cleaning process or charging, etc., the user can also understand the state of the cleaning device by observing the screen display content when standing in front of the cleaning device. The best visible range is expanded, and the screen display direction is not only applicable to the observation during the working state, but also takes into account the maximized visibility in multiple directions.

[0130] See Figure 4 As shown, when the user is using the cleaning device and the body 15 is in a reclined state, the user can hold the second side 49 of the handle 31 or the connection between the second side 49 and the first side 48, and the user can see the content displayed on the screen assembly 53. In the upright case, as Figure 2 shown, the user can observe the content displayed on the screen assembly 53 in front of the cleaning device.

[0131] In the solution of this embodiment, the first side 48 on the front side of the handle 31 is a convex arc facing forward, and the second side 49 is a diagonal line extending backward and upward from the top of the first side 48. Such a design makes the shape of the handle 31 smoother and also facilitates the user to observe the screen display content during use. Also, such a design expands the grippable area of the handle 31. For example, when the body 15 is reclined at a certain angle, the user can hold the second side 49; when the body 15 is in a lying flat state or close to the lying flat angle, the hand can move forward to hold the screen area. In this embodiment, the screen assembly 53 is a non-touch screen assembly, and the user can use the screen assembly as a part of the gripping portion of the handle.

[0132] The screen of the screen assembly 53 may have at least one display area. If there are two display areas on the screen, one area can display text, animations, pictures, etc.; the other area is used to display light effects (such as red lights, blue lights, yellow lights, etc.); the two display areas can each account for half.

[0133] At the front end of the holding part of the handle 31, that is, at the end where the second side 49 is connected to the first side 48, a button assembly 52 is provided. The button assembly 52 may include at least one button. When the button assembly 52 includes multiple buttons, the size of the buttons can be reduced as much as possible within a reasonable range, and the positions of the buttons can be made as close to the screen assembly 53 as possible. The inclination angle of the screen is as large as possible to ensure a reasonable viewing angle during use, and the overall appearance surface of the handle 31 remains smooth and flat.

[0134] In this embodiment, the existing space is fully utilized. The single-curved screen assembly 53 is arranged at the front end of the handle 31 to ensure the visible range of the screen and the comfort of user operation. The overall volume of the handle 31 is reduced, and the structure is more compact. The layout design of the screen assembly 53 makes full use of the space on the front side of the handle 31, which is consistent with the bending radian of the appearance surface of the handle 31 and fits as closely as possible to the outer surface. The compact layout makes the width and thickness of the handle 31 smaller, more comfortable to hold, and at the same time, the overall shape of the machine is more regular and beautiful.

[0135] The liquid storage barrel 2 of this embodiment may have two spaces, which are distributed vertically. See Figure 22 and 23 As shown, the upper space of the liquid storage barrel 2 is a sewage storage space 59, and the lower space is a clean water storage space 60. As Figure 26 shown, the middle is separated by a deformable partition 121. For example, the partition 121 may include a soft film structure 61. The dry recycling barrel 3 is communicated with the sewage storage space 59. Figure 22 shows the concave form of the soft film structure 61, Figure 23 shows the convex form of the soft film structure 61. As Figure 26 and 27 shown, the liquid storage barrel 2 is provided with a sewage inlet pipe 26 and a water injection pipe 62. The sewage inlet pipe 26 is arranged vertically. See Figure 5 and Figure 24 shown, the bottom inlet of the sewage inlet pipe 26 is located below the partition 121 and above the bottom wall of the liquid storage barrel. One end of the sewage inlet pipe 26 is communicated with the middle pipe 27 on the floor brush 1, and the other end is communicated with the sewage storage space 59. Figure 24The liquid flow direction of sewage entering the sewage storage space 59 through the sewage inlet pipe 26 is shown. One end at the top of the water injection pipe 62 is the water injection port, and the other end at the bottom is communicated with the fresh water storage space 60. The whole water injection pipe 62 extends along the vertical direction, and the bottom end is communicated with the fresh water storage space 60 in the vertical direction. A water spraying pipeline is further arranged on the floor brush 1. The fresh water storage space 60 is communicated with the water spraying pipeline through a water valve 72 arranged at the bottom. The water valve 72 is located in front of the sewage inlet pipe 26. In this embodiment, the sewage inlet pipe 26 and the water injection pipe 62 are arranged outside the storage barrel 2 and are respectively arranged on the two lateral sides of the storage barrel 2. The two rear side corner joints of the storage barrel 2 are recessed inward to form avoidance spaces. The sewage inlet pipe 26 and the water injection pipe 62 are respectively arranged in the corresponding avoidance spaces. The sewage inlet pipe 26 is arranged in the left avoidance space, and the water injection pipe 62 is arranged in the right avoidance space. Refer Figure 33 As shown, the cross-section of the storage barrel 2 with avoidance spaces on both sides forms a convex shape. The sewage inlet pipe 26 and the water injection pipe 62 are respectively located in the corresponding depressions of the convex cross-section. The sewage inlet pipe 26 and the water injection pipe 62 are designed separately from the storage barrel 2, which can avoid the reduction of the sealing performance caused by the sewage inlet pipe or the water injection pipe being located in the internal space of the storage barrel, and cannot ensure the separation of the sewage storage space 59 and the fresh water storage space 60. Moreover, the manufacturing difficulty of the storage barrel 2 can be reduced through the separate design of the sewage inlet pipe 26 and the water injection pipe 62.

[0136] The sewage storage space 59 and the fresh water storage space 60 are air-communicated to achieve air pressure balance under the same storage barrel. Further, as Figure 35 shown, an air hole 63 is arranged at the upper part of the sewage storage space 59; the sewage storage space 59 and the fresh water storage space 60 balance the air pressure through the air hole 63, and the setting of the air hole 63 will not cause the mixing of the clear water and sewage in the two spaces. The water injection pipe 62 is provided with an air hole corresponding to the air hole 63 of the sewage storage space 59. After the water injection pipe 62 is installed in the corresponding avoidance space of the storage barrel 2, the two air holes are aligned front and back. A soft rubber connecting member 117 is inserted into the two air holes to connect the clear water and sewage storage spaces, as Figure 35 shown.

[0137] Among them, the partition member 121 is obliquely arranged, with the front end lower and the rear end higher. More specifically, the soft film structure is obliquely arranged, with the front end lower and the rear end higher. Similarly, the front and back here respectively correspond to the front end and the rear end of the floor brush 1. As Figure 25 shown, a pivotable water injection cover is arranged at the water injection port at the top of the storage barrel to seal or open the water injection port.

[0138] As Figure 26 and 27 shown, both the sewage inlet pipe 26 and the water injection pipe 62 are located at the rear side of the storage barrel 2; in the horizontal direction, the dry recovery barrel 3 is located between the sewage inlet pipe 26 and the water injection pipe 62. AsFigure 27 As shown, a fixed limit structure 130 is provided at the lower part and / or the upper part of the sewage inlet pipe 26. Specifically, the fixed limit structure 130 may be limit blocks evenly distributed along the circumferential direction of the sewage inlet pipe 26. At the corresponding position of the liquid storage barrel 2, there is a fixed structure 131 (as Figure 27 shown). The fixed limit structure 130 is embedded in the fixed structure 131 to realize the installation and positioning of the sewage inlet pipe, so that the sewage inlet pipe 26 is suspended and exposed outside the liquid storage barrel 2 through the fixed limit structure 130. The sewage inlet pipe is installed in the vertical direction.

[0139] The liquid storage barrel 2 is provided with a second communication port 118 communicating with the dry recovery barrel 3 at the rear wall of the sewage storage space 59. In the front-rear direction, the second communication port 118 is located behind the bent channel. Among them, the bent channel refers to the channel provided on the barrel cover and communicating with the outlet of the sewage inlet pipe mentioned above. See Figure 29 shown, the second communication port 118 is arranged on the rear wall of the sewage storage space 59 and is set away from the soft film structure. A water retaining eaves 64 is arranged in the sewage storage space 59. The water retaining eaves 64 is formed by extending forward from the rear wall. Looking down from top to bottom, the water retaining eaves is integrally arc-shaped and arranged on the rear wall of the sewage storage space; the water retaining eaves 64 is located below the second communication port 118; the dry recovery barrel 3 is communicated with the sewage storage space 59 through the second communication port 118. The water retaining eaves 64 can block liquid from entering or splashing into the second communication port 118. The second communication port 118 corresponds to and communicates with the first communication port 68 on the fuselage 15. After the liquid storage barrel 2 is installed on the floor brush, the second communication port 118 is then communicated with the first communication port 68 on the fuselage 15. The dry recovery barrel 3 is installed on the fuselage 15, and the sewage inlet on the dry recovery barrel 3 corresponds to and penetrates through the first communication port 68 on the fuselage 15. Specifically, the second communication port 118 is communicated with the dry recovery barrel 3 through a connecting piece arranged at the first communication port 68. Combining Figure 27 with Figure 29 it can be seen that in the front-rear direction, the second communication port 118 is located behind the bent channel.

[0140] Such as Figure 25As shown, a water injection port 119 communicating with the clean water storage space is provided beside the handle 66. The water injection port 119 is provided with a pivotable water injection cover 120 to seal or open the water injection port 119. Assuming there is no liquid in the sewage storage space 59, when injecting water into the clean water storage space 60, it is necessary to open the water injection cover 120 provided beside the handle 66 on the storage bucket 2 and add water from the top of the storage bucket 2. The water injection port 119 located at the top of the storage bucket 2 is communicated with the injection port of the water injection pipe 62, and the cleaning liquid can be injected into the clean water storage space 60 located below the sewage storage space 59 through the water injection pipe 62. That is to say, the water injection pipe 62 is vertically arranged, and the bottom of the water injection pipe 62 is communicated with the top of the clean water storage space. The height of the docking port 122 at the rear side of the partition 121 is not lower than the soft film structure to prevent the clean water storage space higher than the docking port 122 from not being injected with the cleaning liquid. Through the above-mentioned water injection port 119, water can be continuously injected into the clean water storage space and the soft film structure 61 can be gradually lifted by the water pressure, and the bulging soft film structure dynamically increases the liquid storage volume of the clean water storage space 60. Among them, the bottom of the water injection pipe 62 is located at the high position of the inclined soft film structure 61, so that more water can be injected. The partition 121 has a soft film structure. Refer Figure 26 , the central part of the partition 121 is the soft film structure 61, and the other parts are plastic parts. The soft film structure 61 ensures the dynamic adjustment of the water volume in the two spaces, and the other plastic parts can be integrally formed with the upper and lower barrel bodies by ultrasonic welding or other methods to complete the sealing of the barrel body; the bottom of the water injection pipe 62 is also communicated with the docking port 122 provided behind the partition 121. The docking port 122 is also inclined, with the front end lower and the rear end higher. The docking port 122 is located at the rear side of the partition 121, that is, the docking port 122 is located at the rear side of the soft film structure.

[0141] During use, clean water is discharged outward through the bottom water valve 72, and the soft membrane structure 61 supported by the clean water will gradually sink, giving the occupied volume to the sewage storage space 59, so as to dynamically adjust the volume of the clean and sewage storage spaces. During use, due to the negative pressure on one side of the sewage storage space 59, if the clean water storage space 60 is connected to the atmosphere, the soft membrane structure 61 will swell directly, causing the soft membrane structure to fail. However, if the clean water storage space 60 is completely closed during use, because there is a negative pressure on one side of the sewage storage space 59 (due to the effect of the suction airflow), the air already in the clean water storage space 60 will expand until the pressure in the clean water storage space 60 is consistent with the pressure in the sewage storage space 59, and the soft membrane structure 61 will swell slightly, thereby reducing the volume of the sewage storage space. In the subsequent drainage process, the pump 13 needs to resist the negative pressure on the sewage storage space 59 side. As the amount of water gradually decreases, the soft membrane structure 61 will gradually concave, but as the amount of water decreases, the negative pressure on the clean water storage space 60 side will gradually increase, resulting in the inability to pump out the clean water. To this end, the present application connects the clean water storage space 60 with the sewage storage space 59 to ensure that the pressures of the two spaces are balanced, that is, the sewage storage space 59 and the clean water storage space 60 balance the air pressure through the air hole 63 and the water injection pipe 62.

[0142] The corresponding mechanism is set on the whole machine to ensure that when the liquid storage barrel 2 is placed, Figure 6 and Figure 55 The water filling cover 120 is shown in a closed and sealed state. A water filling cover baffle 123 is provided on the body 15, and the water filling cover baffle 123 is arranged corresponding to the water filling cover 120. If the user forgets to close the water filling cover 120 after adding clean water to the liquid storage barrel 2, when the liquid storage barrel 2 is placed on the floor brush, the water filling cover baffle 123 abuts against the flip-over water filling cover 120, so that the water filling cover 120 flipped back is supported by the water filling cover baffle 123, and the water filling cover 120 automatically flips back to close, so that the water filling cover is automatically closed without the user manually closing the water filling cover, that is, the water filling cover 120 in the flipped state will abut against the water filling cover baffle 123 during the placement process, and the water filling cover 120 gradually approaches the water filling cover baffle 123 until the liquid storage barrel 2 returns to its position. As the water filling cover 120 and the water filling cover baffle 123 approach each other, the water filling cover baffle 123 will hold the opened water filling cover 120 and return it to its original position, so that the water filling cover 120 is turned back to the top of the water filling pipe 62. Secondly, the soft film structure 61 is also arranged obliquely to ensure that the water splashed or falling on the soft film structure 61 is rebounded by the elastic soft film structure 61 and then splashed forward to the front wall of the liquid storage barrel, thereby reducing the risk of water entering the main motor 4 and preventing the splashed water from flying to the vicinity of the second connecting port 118 and being sucked into the dry recovery barrel or the inside of the main motor.

[0143] In this embodiment, since the carpet cleaning machine uses a large amount of water, the soft film structure 61 needs to bulge and concave frequently. In this embodiment, both the sewage inlet pipe and the water injection pipe 62 are moved outside the barrel to ensure the integrity of the soft film structure 61. In addition, the soft film structure 61 is designed in a wavy shape to ensure the pre-deformation trend of the soft film structure 61 and reduce the force on the soft film structure 61. Here, the wavy shape means that when the soft film structure is in a convex or concave state, the soft film wall of the soft film structure is wavy, rather than a smooth arc. Also, as Figure 27 and 31 shown, the partition member 121 includes the soft film structure 61 and the plastic member 124 outside the soft film structure. In this way, the partition member 121, the plastic housing corresponding to the sewage storage space, and the plastic housing corresponding to the clean water storage space can be made into an integrated structure of the storage barrel 2 through processes such as ultrasonic welding or other methods.

[0144] Many existing cleaning devices are equipped with a clean water bucket and a sewage bucket, which are used to store clean water and sewage respectively, that is, the clean water bucket and the sewage bucket are set separately. During the user's use process, it is necessary to take two buckets, which causes inconvenience to the user. For example, when taking the clean water bucket for replenishing water or pouring water, and taking the sewage bucket for dumping and cleaning, the user cannot operate the two buckets simultaneously. To simplify the user operation process, in this embodiment, the clean water bucket and the sewage bucket are combined into one bucket, and a variable-shaped soft film structure 61 is used to separate them in the middle of the bucket. Or, the liquid storage space in a single bucket is separated into two independent liquid storage spaces by the soft film structure 61 to store clean water and sewage respectively. The soft film structure dynamically adjusts the two liquid storage spaces to increase the space utilization rate and reduce the volume of the storage barrel.

[0145] See Figure 27 shown, at the top of the storage barrel 2, that is, the handle 66 at the top of the sewage storage space 59, which is convenient for the user to take the storage barrel 2. The handle 66 has a grip for people to hold, and the water injection cover 120 is arranged beside the grip, so as to be integrated with the grip visually, improve the aesthetics of the handle 66, and also make the water injection port 119 located at the top of the storage barrel 2, which is convenient for the user to inject water. Or, the handle 66 includes a grip area for the user to hold and a water injection area for water injection. The grip area is the handle, and the water injection area has a flip-up water injection cover 120. A bucket cover 65 of the sewage storage space 59 is arranged in front of the handle 66. The bucket cover 65 is detachable to facilitate the user to pour out the dirt. At the same time, since the water injection port of the clean water storage space is located at the rear side, that is, at the rear side of the soft film structure, when pouring the sewage, in the presence of clean water, the clean water converges at the front side of the storage barrel away from the water injection port, avoiding the problem of clean water flowing out from the water injection pipe when pouring the sewage. A storage barrel unlocking button 67 is arranged on the handle 66, and a movable lock 69 is arranged on the rear wall of the storage barrel 2. The movable lock 69 is used to be buckled with the groove buckle 125 on the wall of the fuselage 15 (see Figure 6), thus realizing the locking and fixing of the liquid storage bucket 2. The movable latch 69 is located above the second communication port 118 of the liquid storage bucket 2. A locking block 126 that protrudes outward and has an inclined latch surface is also provided below the second communication port 118, and the locking block 126 is immovable. The movable latch 69 is linked with the unlocking button 67. When the user presses the unlocking button 67 to make the latch 69 move to the unlocked state, the user can remove the liquid storage bucket 2 from the floor brush. Among them, the first communication port 68 on the middleware 127 is a through hole penetrating the middleware. One end of the through hole is communicated with the second communication port 118 on the liquid storage bucket 2, and the other end is communicated with the sewage inlet of the dry recovery bucket 3.

[0146] Further, as Figure 22 and 23 shown, a detector 70 can also be provided in the sewage storage space 59. As Figure 2 shown, a connector 71 (such as a pogo pin) for docking with the detector 70 is provided at the corresponding position on the body 15. After the liquid storage bucket 2 is installed on the floor brush 1, the detector 70 just corresponds to the connector 71. Specifically, as Figure 2 shown, two symmetric connectors 71 are provided on the body 15. As Figure 27 shown, corresponding to the two connectors 71, two detectors 70 can also be provided in the sewage storage space 59.

[0147] The above detector 70 is used to detect whether the sewage storage space 59 is full of water. The detector 70 can be provided on the inner wall or the outer wall of the sewage storage space 59, and is located above the soft film structure 61. More specifically, referring to Figure 22 and 23 shown in the example, a pair of detectors 70 are located above the high-position side of the inclined soft film structure 61 and are provided on the inner wall of the liquid storage bucket. When the sewage water level rises to the pair of detectors 70, the sewage conducts the two detectors 70 to each other, thus generating a sewage full signal. In this way, after the full signal, the control device receives the full signal and controls the corresponding device (such as an interaction device, etc.) to output a full water prompt, such as a voice broadcast of the sewage full prompt and / or a display of the sewage full prompt.

[0148] As Figure 8As shown, in the horizontal direction, the inlet end nozzle of the sewage inlet pipe and the water valve 72 are on the same side of the floor brush 1, that is, the left side, and the brush roll motor for driving the brush roll 8 is on the other side, that is, the right side. A liquid storage bucket slot 28 is provided on the floor brush 1. A water valve 72 is provided at the bottom of the liquid storage bucket slot 28. After the liquid storage bucket 2 is inserted into the liquid storage bucket slot 28, the water outlet of the clean water storage space 60 is docked with the water valve 72. When the pump 13 starts to work, the water valve 72 is opened, and the clean water in the clean water storage space 60 flows out from the water valve 72 and into the water spraying device 14. The outlet end nozzle of the sewage inlet pipe is docked with the inlet above the sewage storage space 59.

[0149] Further, as Figure 37 shown, a water spraying device 14 is also provided on the floor brush 1; the water spraying device 14 is communicated with the water spraying pipeline to spray the cleaning liquid in the clean water storage space 60 onto the brush roll 8. See Figure 12 shown, the water spraying device 14 is located above the brush roll 8. The water spraying device 14 includes an upper shell 73, a lower shell 74 and a water inlet nozzle 75; a water inlet nozzle 75 for connecting with the water spraying pipeline is provided on the upper shell 73; a fluid channel is formed between the upper shell 73 and the lower shell 74. It is formed by combining an upper shell 73 and a lower shell 74 to form a cavity with a single channel communicating in the horizontal direction. The water flow is transported by the pump 13, enters the cavity through the water inlet nozzle 75 of the upper shell 73, and then evenly flows out from each nozzle 77 of the lower shell 74. As Figure 38 shown, the upper shell 73 is fixedly installed on the lower shell 74 and is fixed to the lower shell 74 by ultrasonic welding to form a fluid channel, and the aperture of each nozzle provided on the lower shell 74 is the same.

[0150] See Figure 40 、 41 and 42 shown, because the water inlet nozzle 75 is arranged leaning towards one side, it is necessary to make the side with more nozzles 77 receive more water. Therefore, an angular water dividing part 132 extending obliquely protrudes from the outer wall of the nozzle 77 opposite to the water inlet nozzle 75. The water dividing part 132 extends obliquely relative to the water inlet nozzle 75, and by means of the inclination, the side with more nozzles 77 obtains more water, so as to balance the water inflow of the nozzles 77 on both sides of the water inlet nozzle 75.

[0151] As Figure 38 、 39As shown in FIGS. 40, a plurality of nozzles 77 are provided on the lower housing 74; corresponding to the positions of different nozzles 77, the sizes of the first gaps 76 in the up-and-down direction between the upper housing 73 and the lower housing 74 are different; the first gap 76 is related to the distance of the nozzle 77 from the water inlet nozzle 75. For example, the farther the distance from the water inlet nozzle 75, the larger the first gap 76; the closer the distance from the water inlet nozzle 75, the smaller the first gap 76. Since the distances of each nozzle 77 from the water inlet nozzle 75 are not equal, by designing the first gaps 76 corresponding to different nozzles 77 to be of different sizes, the water pressure of each nozzle 77 can be balanced, achieving the purpose of uniform water outlet, without the need to adjust the water outlet aperture of each nozzle. Among them, Figure 38 is Figure 40 a schematic cross-sectional view of the structure shown.

[0152] Referring to Figure 38 the example shown, the upper housing 73 and the lower housing 74 are combined. The upper housing 73 and the lower housing 74 have a first gap in the up-and-down direction and a second gap in the front-and-back direction. The corresponding space of the second gap is the water storage chamber 78. The liquid entering from the water inlet nozzle 75 flows into the water storage chamber 78; the liquid in the water storage chamber 78 flows into the gap 76 only when the liquid level line in the water storage chamber 78 reaches and exceeds the top of the nozzle 77, which is equivalent to the overflowing liquid in the water storage chamber 78 entering the first gap 76, and then entering the nozzle 77 through the first gap 76 and flowing out.

[0153] When the apertures of a plurality of water spraying holes are the same, through the first gap 76 between the upper and lower covers of the water spraying plate and the water storage chamber 78 located behind the first gap 76, dripping of the water spraying holes when not working is avoided. The liquid entering from the water inlet nozzle 75 flows into the water storage chamber 78; when the water storage chamber 78 is full of liquid, the overflowing liquid will enter the first gap 76 (such as Figure 39 ) and then is conveyed to each nozzle 77 through the first gap 76, so that a plurality of nozzles 77 discharge water evenly. In the vertical direction, the plane where the top wall of the water storage chamber 78 is located is higher than the plane where the top of the nozzle 77 is located, and the first gap 76 is located above the nozzle 77. In the front-and-back direction, the water storage chamber 78 is located behind the first gap 76 and is communicated with the first gap 76. The first gap 76 can also be called an adjustment chamber, and the adjustment chamber is used to balance the water pressure of each nozzle 77 to achieve the purpose of uniform water outlet. Referring to Figure 38 shown, in the up-and-down direction, the thickness h of the adjustment chamber is less than the thickness H of the water storage chamber 78.

[0154] In other embodiments, the height of the gap in the transverse direction can be unchanged, and the water spraying pressure is adjusted by adjusting the aperture size of the water spraying hole; the existence of the water storage chamber can still ensure that the residual liquid in the water spraying device does not flow out from the nozzle after use, affecting the user experience.

[0155] Referring to Figure 36Another embodiment is shown. To avoid residual water flowing out of the nozzle after the water spraying ends, a tee pipe 79 and a pressure valve 80 are added to the water path between the pump 13 and the water spraying device 14. The pressure valve 80 has the characteristic of unidirectional flow or is a functional valve (such as a solenoid valve) that can switch the on / off state. Two ports of the tee pipe 79 are respectively connected to the water paths of the pump 13 and the water spraying device 14 to form a conventional water delivery pipeline. The last port is connected to one end of the pressure valve 80, and the other end of the pressure valve 80 is directly connected to the atmosphere. Since the outlet resistance of the end of the pressure valve 80 directly connected to the atmosphere is greater than the outlet resistance of the nozzle 77, water flows through the conventional water delivery pipeline and does not leak from the pressure valve 80. After the cleaning device stops, the pump 13 stops working. At this time, the unidirectional flow characteristic of the pressure valve 80 makes the atmospheric pressure at the pressure valve 80 the same as the atmospheric pressure at the nozzle 77, and the water in the water path quickly flows out from the nozzle 77 under the action of gravity; in this way, the residual water in the water path can be discharged.

[0156] In this embodiment, a photoelectric sensor 81 can be used to detect whether there is still clean water in the clean water storage space 60. The photoelectric sensor 81 can be arranged on the water path between the pump 13 and the water spraying device 14. Since this section of the water pipe is always emptied after each use, the transparent shell or transparent pipe wall of the photoelectric sensor 81 is not easily damaged by chemical solvents or attached by other non-transparent substances, thereby improving the reliability of the photoelectric sensor 81 and extending the service life of the photoelectric sensor 81.

[0157] Among them, the pressure valve 80 can be a water valve 72 such as a Tesla valve, a capillary tube, a duckbill valve, a check valve, a globe valve, etc. that has the characteristic of unidirectional flow and can automatically control the flow direction. The end with a small outlet pressure is connected to the atmosphere, and the end with a large pressure is connected to the tee pipe 79. Air / water easily flows from the atmosphere end to the tee end, and it is not easy to flow from the tee end to the atmosphere end. After the pump 13 stops working, since the end of the pressure valve 80 and the nozzle 77 are both connected to the atmosphere, the water in the pipeline will quickly flow out from the water spraying hole under the action of gravity.

[0158] In another implementation solution, Figure 36 the pressure valve 80 in it is cancelled, a pressure relief pipe is connected, and the height of the outlet of the pressure relief pipe is raised so that the outlet resistance of this section of the water pipe is greater than the water outlet resistance of the nozzle 77. At this time, the water will flow out from the nozzle 77 and will not flow out from the pressure relief pipe.

[0159] Alternatively, the pressure valve 80 is replaced with a water valve 72 such as a solenoid valve, a ball valve, a diaphragm valve, etc. that actively controls the fluid flow direction and flow rate. After the pump 13 stops working, the pressure valve 80 is opened again so that the end of the pressure valve 80 and the nozzle 77 are both connected to the atmosphere, and the water in the pipeline quickly flows out from the water spraying hole under the action of gravity.

[0160] Alternatively, a duckbill valve-style soft rubber material is coated on the nozzle 77, and the water outlet position is at the duckbill valve at this time. When the pump 13 operates, the duckbill valve will open under the pressure of the pump 13. After the pump 13 stops working, due to the elastic closing force of the duckbill valve itself and the negative pressure in the pipeline, it is difficult for water to leak. Or, directly use the duckbill valve to replace the nozzle 77.

[0161] Further, the cleaning device provided in this embodiment may further include a first temperature sensor. The first temperature sensor is disposed at the suction nozzle 5 or in the suction nozzle passage 25 communicating with the suction nozzle 5. The control device is electrically connected to the first temperature sensor and is configured to obtain the temperature information collected by the first temperature sensor after the heating component 7 operates, determine the temperature change information, and determine the dryness degree of the cleaning object according to the temperature change information.

[0162] One possible implementation is that there is a first temperature sensor in the suction nozzle passage 25 for detecting the dryness degree of the cleaning object. Among them, the determination process of the control device may include the following steps:

[0163] S21. Obtain the temperature information collected by the first temperature sensor.

[0164] S22. Determine the temperature change information according to the collected temperature information.

[0165] Among them, the temperature change information may be the slope of the temperature change curve. Taking the cleaning object as a carpet as an example, generally, the average temperature change of a wet carpet is not significant, and the slope of the corresponding temperature change curve is small; after the carpet dries, the temperature will suddenly rise, and the slope of the corresponding temperature change curve will suddenly become large. Therefore, the dryness degree of the carpet can be judged by the slope change.

[0166] S23. Determine the dryness degree of the cleaning object according to the temperature change information.

[0167] Specifically, if it is determined based on the temperature change information that the temperature rise slope is greater than the set value, it is determined that the dryness degree of the cleaning object reaches the dry level; if it is determined based on the temperature change information that the temperature rise slope is less than or equal to the set value, it is determined that the dryness degree of the cleaning object does not reach the dry level and belongs to the wet level.

[0168] Still further, as Figure 5As shown, the cleaning device may further include a humidity sensor 82; the humidity sensor 82 is disposed at the bottom of the floor brush 1 for detecting the surface humidity of the cleaning object; the control device is electrically connected to the humidity sensor 82 and is configured to determine the surface humidity of the cleaning object according to the humidity information collected by the humidity sensor 82. Although the humidity sensor 82 is disposed in front of the air outlet of the heating assembly 7 and is spaced apart from it by a certain distance to ensure that it will not be affected by the hot air from the air outlet, in actual operation, due to the front suction nozzle 5 contacting the cleaning object (such as a carpet) to form a quasi-sealing effect, the hot air output by the heating device is difficult to reach the position where the humidity sensor 82 is located and will not affect the detection of the humidity sensor 82.

[0169] See Figure 10 and 11 In the example shown, an intermediate pipe 27 connecting the suction nozzle channel 25 and the dirt inlet pipe 26 is provided on the floor brush 1. A plurality of branch pipes may be provided on the intermediate pipe 27, and the cross-sectional size of the branch pipes is much smaller than the cross-sectional size of the intermediate pipe 27. For example, the plurality of branch pipes include: a first branch pipe 83, a second branch pipe 84, and a third branch pipe 85. The first branch pipe 83 communicates with the humidity sensor 82 to provide negative pressure to the humidity sensor 82. The second branch pipe 84 communicates with the roller brush motor 12 on the floor brush 1 and is used to suck the heat generated during the operation of the roller brush motor 12. The installation position of the first temperature sensor is at the third branch pipe 85. The first temperature sensor is a temperature probe inserted into the intermediate pipe 27 through the third branch pipe 85 for detecting the temperature of the suction air flow in the intermediate pipe 27.

[0170] The humidity sensor 82 disposed at the bottom of the floor brush 1 is used to detect the surface humidity of the cleaning object. When the surface humidity is lower than a certain threshold, the humidity sensor 82 emits a signal to determine that the surface of the cleaning object is dry and belongs to the semi-dry level. In the embodiment of the present application, the detection principle differences between the first temperature sensor and the humidity sensor 82 can be utilized. Both the first temperature sensor and the humidity sensor 82 can detect dryness, but the recognition principles used are different. When the first temperature sensor emits a dry signal, the carpet is in a completely dry state, and when the first temperature sensor emits a wet signal, the carpet is in a wet state. When the humidity sensor 82 emits a dry signal, the carpet is in a state where the surface is dry but the inside is not dry. By utilizing the differences between the two sensors, the detection of the three states of wet, semi-dry, and completely dry of the carpet can be realized.

[0171] Correspondingly, the cleaning device may further include a prompting device. The prompting device is disposed on the floor brush 1; the control device is electrically connected to the prompting device.

[0172] Wherein, the control device is configured to:

[0173] When it is determined that the humidity on the surface of the cleaning object exceeds the humidity threshold based on the humidity information collected by the humidity sensor 82, control the prompting device to output a prompt message indicating high humidity;

[0174] When it is determined that the humidity on the surface of the cleaning object is lower than or equal to the humidity threshold based on the humidity information collected by the humidity sensor 82, control the prompting device to output a prompt message indicating semi-dry;

[0175] Based on the temperature information collected by the first temperature sensor, determine the temperature change information. When it is determined that the dryness degree of the cleaning object meets the full-dry requirement according to the temperature change information, control the prompting device to output a prompt message indicating full dry.

[0176] For example, the prompting device may be, but is not limited to: a voice broadcast device, a prompting light that can emit different colors of light based on different prompt messages, a display screen, and the like.

[0177] Taking the prompting light as an example, both sides of the floor brush 1 are provided with wet-dry and drying indicator lights. The indicator light has three colors: red light - orange light - blue light. As Figure 3 and 53 shown, the prompting light 129 can be arranged on both sides of the bottom of the floor brush 1 and is located between the roller brush and the roller. The prompting light 129 has an arc-shaped illumination surface facing the bottom and the outside. The red light means that the first temperature sensor in the suction nozzle 5 identifies that the current area of the carpet is dry (at this time, the carpet is in a fully dry state, that is, both the top and the root of the carpet hair are dry). The blue light means that the humidity sensor 82 identifies that the current area of the carpet is wet. The orange light means that the humidity sensor 82 detects that the surface of the current area is in a dry state (the actual state of the carpet is that the surface is dry but the inside is not dry, which is equivalent to the top of the carpet hair being dry and the root being wet). When the humidity sensor 82 detects that the carpet is dry (surface dry), the indicator light emits orange light. The user can choose to continue drying in the current area or choose to enter the drying of the next carpet area. When the carpet machine moves to an undried area, the humidity sensor 82 detects that the current carpet is wet, and the indicator light emits blue light. The above-mentioned indicator light only works during the carpet drying operation.

[0178] Furthermore, on the basis of setting the first temperature sensor, a second temperature sensor can also be set on the floor brush 1. The position where the second temperature sensor is set is not specifically limited, and it is preferably a position not affected by the temperature of the fuselage 15. The second temperature sensor is used to detect the ambient temperature. Drying is achieved when the temperature detected by the first temperature sensor is at least higher than the ambient temperature detected by the second temperature sensor. Optionally, when the temperature detected by the first temperature sensor is at least 2°C higher than the ambient temperature, it can be determined that the cleaning object reaches the dry level. By setting redundancy, false alarms are avoided to ensure that the drying object is fully dry. Correspondingly, the determination process of the control device may include the following steps:

[0179] S231. Obtain the ambient temperature detected by the second temperature sensor;

[0180] S232. If the temperature collected by the first temperature sensor exceeds the ambient temperature and the excess amount is greater than or equal to the set amount, determine that the dryness level of the cleaning object reaches the dry level;

[0181] S233. If the temperature collected by the first temperature sensor does not exceed the ambient temperature, determine that the dryness level of the cleaning object does not reach the dry level and belongs to the wet level.

[0182] Further, the first temperature sensor can also be a non-contact temperature detection sensor, such as an infrared temperature sensor, etc. This first temperature sensor is not arranged in the suction nozzle passage 25 and can be arranged at the bottom of the floor brush 1 or the bottom of the body 15. The non-contact first temperature sensor is used to measure the temperature of the cleaning object (such as a carpet), and the dryness level of the cleaning object is judged by the difference or slope between its temperature and the ambient temperature.

[0183] Further, as shown in Figure 10 A pump 13 is also provided on the floor brush 1. An anhydrous detection device is arranged on the output pipeline of the pump 13. The anhydrous detection device can detect whether there is water in the clean water storage space 60 of the liquid storage bucket 2 by detecting whether there is flowing water in the output pipeline of the pump 13. This anhydrous detection device can be a photoelectric sensor 81, etc. One end of the output pipeline of the pump 13 is connected to the pump 13, and the other end is connected to the clean water storage space 60 of the liquid storage bucket 2. Taking the photoelectric sensor 81 as an example, the photoelectric sensor 81 can be arranged at a position of the output pipeline of the pump 13 close to the liquid storage bucket 2. For example, as mentioned above, the photoelectric sensor 81 can be arranged on the water pipeline between the pump 13 and the water inlet nozzle 75 as shown in Figure 36 In. In order to realize rapid anhydrous detection, the photoelectric sensor can be arranged upstream of the pump 13.

[0184] Further, a second sensor 86 for detecting whether the floor brush 1 is on the base can also be arranged on the floor brush 1. This second sensor 86 can be a Hall sensor. The second sensor 86 can be arranged at the bottom of the floor brush 1. More specifically, it can be located between two rollers 9. Correspondingly, a trigger element, such as a magnetic part, which cooperates with the Hall sensor, can be arranged on the base. When the floor brush 1 of the cleaning device is placed on the base and the Hall sensor approaches the trigger element to a certain distance, the Hall sensor is triggered to generate an electrical signal; after the control device receives the electrical signal generated by the Hall sensor, it determines that the cleaning device has been placed on the base and can trigger the self-cleaning program of the cleaning device.

[0185] Another embodiment of the present application also provides a base. This base includes a base body 87 and a cleaning tool 88. As shown in Figures 43 to 50As shown, a bearing structure adapted to the bottom of the floor brush 1 of the cleaning device is provided on the seat body 87. The cleaning tool 88 is detachably connected to the seat body 87. There is a notch 89 on the side wall of the seat body 87, and the cleaning tool 88 is arranged at the notch 89 to fill the side wall notch 89; the position of the cleaning tool 88 corresponds to the position of the roller brush 8 on the floor brush 1; after the cleaning tool 88 is disassembled, one end of the roller brush 8 is exposed through the notch 89, and the roller brush 8 can be disassembled at the notch 89. The roller brush is a press-unlock type, and an unlock button is provided on the end cover of the roller brush. After pressing, the roller brush is unlocked, and then the roller brush can be pulled out from the roller brush cavity.

[0186] As Figure 51 In the example shown, a scraper 90 and a cleaning brush 91 are provided on the cleaning tool 88. The scraper 90 and the cleaning brush 91 are respectively located at two opposite ends of the cleaning tool 88. The cleaning tool 88 further includes a cleaning blade holder 92. For example, the blade of the scraper 90 is embedded at the front end of the cleaning blade holder 92, the cleaning blade holder 92 is rubber-coated and embedded at the side of the blade, and the cleaning brush 91 is hair-implanted and embedded at the tail end of the cleaning blade holder 92. The cleaning tool 88 has two functions. One is to clean the roller brush 8, and the other is to block the notch 89 at the side wall of the base. The notch 89 is used to extract the roller brush 8 and disassemble the roller brush 8 from the floor brush 1. Figure 50 The method shown in is the insertion method and is installed on the base. A slot is provided at the edge of the notch 89 on the side wall of the base, and the cleaning tool 88 can be installed by inserting it into the slot. Of course, other methods can also be adopted, such as the rotary door type. For example, one end of the cleaning tool 88 is inserted into the slot and fixed by the clamping mechanism in the slot; the cleaning tool 88 can rotate relative to the axis of the clamping mechanism, and by rotating the cleaning tool 88, one end of the roller brush 8 can be exposed for convenient extraction. The clamping mechanism is an elastic mechanism. When the user wants to extract the cleaning tool 88 for use, rotate the cleaning tool 88, pinch the other end of the cleaning tool 88 and pull it outwards, and the cleaning tool 88 can be pulled out. Another example is the sliding door type. A chute is provided outside the notch 89 on the side wall of the base, and the cleaning tool 88 can be slid into the chute along one end of the chute to block the notch 89. When the user wants to take out the cleaning tool 88, just slide the cleaning tool 88 out of the chute from the end of the chute.

[0187] This embodiment eliminates the operation of frequently lifting and placing the cleaning device and can quickly take and place the roller brush 8. The user can also use the cleaning tool 88 to cut and clean the hair wound around the roller brush 8.

[0188] As Figure 43 、 45and 47, a sunken groove 93 is provided on the base body 87. The top of the groove wall of the sunken groove upwardly supports the floor brush of the cleaning device. The cleaning device is placed on the base, and the area from the self-priming nozzle at the bottom of the floor brush to the air outlet duct is above the sunken groove. There is a gap between the roller brush on the floor brush and the bottom of the sunken groove so that the roller brush is in a suspended state. At least part of the top of the groove wall of the sunken groove 93 is provided with a sealing device 94, that is, a sealing device is arranged around the top surface of the groove wall forming the sunken groove 93. The sealing device 94 can be a rubber part, a foam part or other soft rubber materials. Ensure that after the floor brush 1 is placed on the base body 87, the bottom edge of the floor brush abuts against the sealing device under the action of the self-gravity of the cleaning device, realizing the seal between the bottom edge of the floor brush and the top surface of the groove wall of the sunken groove 93, and the top of the groove wall of the sunken groove upwardly supports the floor brush of the cleaning device. The area from the self-priming nozzle 5 at the bottom of the floor brush 1 to the heating component 7 is above the sunken groove 93. The suction nozzle 5, the heating component 7 and at least part of the roller brush are located in the space formed by the sunken groove 93, and form a sealed space with the sunken groove 93 through the sealing device 94; the undulation of the bottom of the sunken groove 93 is adapted to the undulation of the bottom of the area of the floor brush 1. For example, the rear end of the groove wall of the sunken groove is high and the front end is low; and / or the rear end of the bottom of the sunken groove is high and the front end is low. Specifically, as Figure 47 shown, the bottom of the sunken groove 93, from front to back, at least includes: a concave arc section L1 and a horizontal straight section L2. Among them, the front end height of the concave arc section L1 is lower than the rear end height. In a specific embodiment, at least part of the top of the groove wall of the sunken groove 93 is provided with a sealing device, and the bottom of the floor brush abuts against the sealing device. For example, Figure 43 shown, the groove wall of the sunken groove 93 includes side walls 932, 934 on the left and right sides, a front wall 931 in the front, and a rear wall 933 in the rear. The top surfaces of the two side walls 932, 934 and the front wall 931 are evenly covered with a sealing device, while only a partial area of the rear wall 933 is covered with the sealing device, and the uncovered area is located at the central part of the top surface of the rear wall 933. Specifically, as Figure 43As shown, the top surface of the rear wall 933 is provided with a notch where there is no sealing device. The existence of this notch can serve as a ventilation opening after the floor brush 1 is placed on the seat body 87, avoiding excessive air pressure in the space between the bottom of the floor brush 1 and the sunken groove 93. In the vertical direction, the top surface of the front wall 931 is lower than the top surface of the rear wall 933, and the top surfaces of the front ends of the two side walls 932 and 934 are also lower than their rear end top surfaces. The top surface 870 of the seat body is a horizontal plane, the top surface of the front wall 931 is formed by being recessed downward from the top surface 870 of the seat body, and the top surface of the rear wall 933 is formed by further extending upward from the seat body 87 and is higher than the top surface 870 of the seat body. The top surfaces of the two side walls 932 and 934 gradually decrease from front to back, gradually decreasing from higher than the top surface 870 of the seat body to lower than the top surface 870 of the seat body. The front end part of the sunken groove sinks below the top surface 870 of the seat body, thereby forming the front wall of the seat body and the two side walls of the seat body surrounding the front area of the sunken groove. A notch is provided on the left side wall 871 of the seat body 87 for the extraction and installation of the roller brush, and the cleaning tool 88 can detachably block the notch 89. The area on the top surface of the rear wall 933 where no sealing device is attached forms a ventilation opening after the cleaning device is placed on the base, avoiding excessive pressure in the space formed by the sunken groove and the cleaning device due to continuous air supply from the air outlet, which may cause sewage to overflow from the front wall 931.

[0189] After the cleaning device is placed on the base, the cleaning device can automatically start the self-cleaning program or start the self-cleaning program under the user's instruction. During the self-cleaning process, the heating component 7 does not work, but the main motor 4 still discharges air flow into the air outlet duct 6, and the suction nozzle also maintains suction, so that the liquid flowing out of the self-spraying device 14 is pushed by the air flow blown out from the air outlet to the front area of the sunken groove for being sucked by the suction nozzle. After the self-cleaning is completed, the cleaning device can enter the drying mode of the roller brush 8. The inlet end of the suction nozzle 5, the roller brush 8, and the air outlet with the heating component 7 are all within this sealed space. After the cleaning device starts the drying mode of the roller brush 8, the roller brush keeps rotating, the main motor 4 works, the suction nozzle 5 sucks air flow, and the air flow enters the main motor 4 of the cleaning device. The air flow in the air outlet duct 6 of the main motor 4 generates hot air flow through the heating component 7; due to the suction effect of the suction nozzle 5, and because the bottom of the sunken groove and the bottom of the floor brush are adapted in undulation, the hot air flow flows along the bottom of the floor brush through the horizontal straight section L2 and then along the concave arc section L1 until the area below the roller brush. The hot air flow is equivalent to sticking to the bottom of the floor brush and flowing along the contour of the bottom of the floor brush, from back to front to the roller brush 8, and then into the suction nozzle 5. The hot air flow flowing through the roller brush 8 can dry the roller brush 8.

[0190] Among them, the front end of the front end of the suction nozzle of the floor brush 1 exactly corresponds to the front edge of the concave arc section L1, so that the front edge of the concave arc section L1 plays a guiding role, and the hot air flow can smoothly enter the suction nozzle along the concave arc section.

[0191] As Figure 43As shown, a collection device 96 is provided in the sunken groove 93; the collection device 96 is located below the front part of the roller brush 8. For example, in a specific and feasible example, as Figure 48 and 49 shown, the collection device 96 may include an upper plate and a lower plate. The upper plate is a flat plate 97, and the lower plate is an arc-shaped plate 98. Among them, the flat plate 97 is adapted to the length of the roller brush 8; through holes penetrating the flat plate are provided on the flat plate 97. The arc-shaped plate 98 extends backward and downward from the front end of the flat plate 97. Through holes penetrating the arc-shaped plate are provided on the arc-shaped plate 98.

[0192] Filter structures are provided on both the flat plate 97 and the arc-shaped plate 98. In one feasible solution, the filter structure on the flat plate can be the through holes provided on the flat plate; similarly, the filter structure on the arc-shaped plate can be the through holes provided on the arc-shaped plate. Correspondingly, the through holes on the flat plate and the through holes on the arc-shaped plate can be called filter holes. As Figure 48 shown in an implementation structure, the filter structure provided on the flat plate 97 can be filter holes vertically penetrating the flat plate 97. The arc-shaped plate 98 extends backward and downward from the front end of the flat plate 97; among them, the filter structure provided on the arc-shaped plate 98 can be filter holes penetrating the arc-shaped plate 98 in the front-back direction or vertically. Or, the filter structure provided on the flat plate 97 and the filter structure provided on the arc-shaped plate 98 are a plurality of horizontal strip-shaped long grooves, etc.

[0193] The collection device 96 is used to collect miscellaneous dirt particles or others that are difficult to be recovered by the suction nozzle 5. The user can take out the net bag with dirt after self-cleaning and rinse it separately. A first connection structure is provided on the collection device 96, and a second connection structure is provided at the corresponding position on the sunken groove. The installation position of the collection device 96 is located below the roller brush of the floor brush 1, as Figure 44 and Figure 50 , the first connection structure can be a groove provided on the collection device 96. The second connection structure provided at the corresponding position at the front end of the sunken groove of the base is a protruding post. When installing the collection device 96, just insert the protruding post into the groove to complete the installation. When disassembling, lift the collection device 96 upward to remove it. In other embodiments, the first connection structure can be an embedding part formed at both ends of the collection device 96, and the second connection structure is a sliding groove structure provided on the side wall, and the embedding part is embedded downward into the sliding groove for installation and fixation. To ensure a certain distance between the collection device 96 and the front wall of the sunken groove, the collection device 96 can also protrude and extend downward to form a support column to the front wall of the sunken groove 93.

[0194] In the solution provided in this embodiment, the cleaning tool 88 is installed at the notch on the side wall of the base, so that the sunken groove of the base forms a closed container, which can be used to store liquid. Here, in order to distinguish the above-mentioned notch as the ventilation port, the notch on the side wall of the base here is called the side wall notch 89. When the cleaning device is placed on the base, when it is necessary to clean the hair of the cleaning roller 8, there is no need to lift the cleaning device out of the base. Just remove the cleaning tool 88 from the base to expose the semi-circular side wall notch 89, and then press the release button at the end of the cleaning roller 8, and the cleaning roller 8 and the floor brush can be unlocked and removed from the side wall notch 89 on the base. The front end of the removed cleaning tool 88 has a metal blade, which can cut the hair on the cleaning roller 8. The cleaning roller 8 is of the type of pressing and side-drawing, and there is no need to open the lower cover 11 of the suction nozzle and then disassemble the cleaning roller 8. The pressing unlock key is integrated on the exposed side surface of the cleaning roller 8.

[0195] See Figure 52a and 52b As shown, the cleaning device is placed on the base. The suction nozzle 5 of the cleaning device is located on the front side of the collection device 96, and the roller brush cavity cover plate 110 of the cleaning device is located above the collection device 96. The cleaning roller 8 of the cleaning device is in a suspended state, that is, there is a certain distance between the cleaning roller 8 and the bottom of the sunken groove 93. After the cleaning device starts self-cleaning, the sewage generated can be sucked into the sewage storage space 59 through the suction nozzle 5. The air outlet duct blows air forward along the sunken groove, pushing the sewage to converge towards the suction nozzle in the front, facilitating the suction nozzle to recover the sewage in the sunken groove. From Figure 52b It can be seen that the collection device is located below the cleaning roller 8, more precisely, below the front part of the cleaning roller. During self-cleaning, the solid particles on the cleaning roller will be scraped off, mainly falling below the front part of the cleaning roller. By setting the collection device here, solid impurities can be collected and not sucked away by the suction nozzle. As Figure 52a shown, after self-cleaning is completed, the cleaning roller 8, the sunken groove 93 of the base, and the collection device 96 are all in a wet state. At this time, the cleaning device can start the drying program. The main motor 4 works, and the heating component 7 works. The hot air flow generated by the heating component 7 at the rear end of the sunken groove 93 flows forward along the sunken groove 93 towards the suction nozzle 5 in the front. At the same time, due to the suction effect of the suction nozzle 5, the hot air enters the suction nozzle 5 through the gap between the cleaning roller 8 and the bottom of the groove after passing through the cleaning roller 8, accelerating the circulation of the hot air and improving the drying efficiency; it stops until the drying requirement is met. Since the cleaning roller 8 of the cleaning device is in a suspended state, the hot air flow reaches the suction nozzle 5 through the bottom of the cleaning roller without being blocked by the cleaning roller 8, and the drying effect will be better. The collection device 96 intercepts and integrates the large-sized dirt after self-cleaning. After drying, the user can easily brush off the dirt on the collection device 96 with the cleaning brush 91. The dirt is easy to handle and does not dirty the hands after being dried.

[0196] Further, as Figure 43As shown, a detachable handle 128 is provided at the rear side of the seat 87, and the handle 128 has a gripping portion, and the user moves the seat 87 through the gripping portion. The handle 128 is also provided with an installation area for accommodating brushes, such as an accommodating groove. The handle 128 extends backward to form a limiting area, that is, the handle 128 can be used as a wall-supporting block, so that when the seat 87 is placed against the wall, it is spaced apart from the wall by one end, so that the cleaning equipment placed on the seat 87 is kept at a certain distance from the wall, and the body is against the wall, which makes it inconvenient to take or there is no space for the cables or external pipes of the cleaning equipment to be entangled.

[0197] The present application also provides a cleaning system in one embodiment. Figures 53 to 55 As shown, the cleaning device is placed on the base. The cleaning device in this embodiment may have all the technical features mentioned in the above cleaning device embodiment. The base in this embodiment may have all the technical features mentioned in the above base embodiment. The specific content can be found above and will not be repeated here.

[0198] The following describes the technical solutions and corresponding effects of the solutions provided in the embodiments of the present application in combination with specific application scenarios.

[0199] Application scenario 1:

[0200] The user uses the carpet cleaning machine to clean the carpet at home. The user touches the start button on the handle 31, the cleaning device is powered on, and the control device controls the absolute pressure sensor 24 to work to collect the first data. The first data is used to determine the reference value for blockage determination. The user operates the body 15 in a similar Figure 14 After the rearward tilting posture shown, the main motor 4 starts working. The user holds the handle 31 to push the body 15. At this time, the power-assistance sensor at the connection between the handle 31 and the connecting rod 16 senses the user's thrust and sends the detected thrust information to the control device. Based on the thrust information, the control device controls the power-assistance motor 30 on the floor brush 1 to work, driving the roller 9 on the floor brush 1 to roll forward to provide power to the user. At this time, the user does not feel that it is difficult to push the cleaning device, but it is very easy, and there is also a feeling that the body automatically moves forward without any effort as long as the handle 31 is lightly supported. When the floor brush 1 cleans the carpet, the water spray device 14 sprays water on the carpet, and the roller brush 8 rotates to scrub the carpet. The sewage generated by cleaning and the solid impurities scrubbed out are sucked into the suction nozzle channel 25 by the suction nozzle 5, and then enter the sewage inlet pipe 26 through the middle pipe 27 on the floor brush 1, and then enter the sewage storage space 59 from the upper part of the sewage storage space 59 through the inlet pipe. The sewage enters the sewage storage space 59. Solid impurities, lint, etc. can follow the suction airflow into the dry recovery barrel 3 through the first connecting port 68 at the upper part of the sewage storage space 59 .

[0201] The absolute pressure sensor 24 continuously collects the second data during the operation of the cleaning device. The control device will determine whether the cleaning device is blocked by comparing the second data with the blockage determination reference value in real time. If blockage occurs, the interactive device on the cleaning device (such as a voice broadcast device, a display screen, etc.) will output a blockage prompt message to prompt the user to clear the blockage.

[0202] After the carpet is cleaned, the cleaning device can start the working mode of drying the carpet. In the drying mode, the heating component 7 continues to work to generate hot air flow; the main motor 4 works. The first temperature sensor and humidity sensor 82 arranged on the floor brush 1 detect the temperature and humidity of the carpet in real time. The control device can determine the dryness of the carpet through the temperature and humidity of the carpet; if the dryness reaches the fully dry level, the control prompt light 129 is controlled to display a red light; when the user sees the red light, he can understand that the current area is dry and can move to the next area. If the dryness reaches the semi-dry level, the control prompt light is controlled to display an orange light; when the user sees the orange light, he can understand that the current area is semi-dry and can consider moving to the next area or drying it for a while. If the dryness reaches the wet level, the control prompt light is controlled to display a blue light; when the user sees the blue light, he can understand that the current area is still very wet and needs to continue drying.

[0203] Application scenario 2:

[0204] After the user has finished using the carpet cleaning machine, the carpet cleaning machine is placed on the base. The area from the self-suction nozzle 5 to the heating component 7 of the floor brush 1 is located in the sunken groove 93 of the base. The Hall sensor on the floor brush 1 is triggered by the trigger on the base. After receiving the trigger signal generated by the Hall sensor, the control device of the cleaning device determines that it is located on the base. At this time, the control device self-checks to detect whether the liquid storage barrel 2 is installed in place, whether the dry recovery barrel 3 is installed in place, whether the sewage storage space 59 is full, and whether the clean water storage space 60 is short of water (enough for this self-cleaning water consumption). If it is detected that the sewage barrel is full, the control device controls the interactive device (such as voice broadcast and / or display) to output a sewage full prompt. After the user sees the sewage full prompt, the liquid storage barrel 2 can be removed from the floor brush 1. After the user has dumped the sewage in the sewage storage space 59, he sees that there is not much water in the clean water storage space 60, so he can fill it up with clean water. The user can complete the dumping of sewage and the injection of clean water by removing one barrel, without having to remove two barrels separately for the operation.

[0205] After the sewage is emptied and the clean water is filled up, the liquid storage bucket 2 can be reinstalled on the floor brush 1. After the control device self-checks and meets the self-cleaning conditions, the self-cleaning program is started. The main motor 4 operates, the pump 13 operates (to spray water through the water spraying device 14), and the roller brush motor 12 operates to drive the roller brush 8 to rotate, so as to clean the roller brush 8. After the self-cleaning program ends, the drying program is started. The main motor 4 operates and the heating component 7 operates to form a hot air flow in the sealed space formed by the floor brush 1 and the sunken groove 93, which goes forward from the heating component 7, passes through the roller brush 8 and reaches the suction nozzle 5, so as to dry the roller brush 8, the suction nozzle channel 25, etc.

[0206] After drying, the user can remove the cleaning device from the base. The user can take out the collection device 96 in the sunken groove 93 and clean it.

[0207] Alternatively, after drying, the user does not need to remove the cleaning device from the base. The cleaning tool 88 on the base is removed, and the roller brush 8 is extracted from the notch 89 to clean the hair wound on the roller brush 8. Of course, the hair on the roller brush 8 can also be cleaned before the self-cleaning program.

[0208] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
