Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning device. Background Art

[0002] In the design of the floor scrubber, the connection method between the sewage bucket and the main structure is based on a detachable structure to achieve rapid dumping and cleaning of the dirt in the sewage bucket.

[0003] However, the existing sewage bucket usually needs to align the sewage inlet at the bottom of the sewage bucket with the matching interface on the main structure before it can be accurately installed in the mounting groove of the main structure, and the mounting groove is generally designed to semi-enclose the sewage bucket, with only the groove open for the sewage bucket to be installed, and the bottom of the mounting groove is generally formed with a downwardly extending groove as a mounting platform, so that the bottom of the sewage bucket can be embedded in the groove and be surrounded by it. The sewage inlet at the bottom of the sewage bucket and the matching interface on the main structure are both located at positions invisible to the user during installation, and the semi-enclosed mounting groove design limits the adjustment space of the sewage tank during installation, which requires the user to accurately align the bottom structure of the sewage bucket with the corresponding groove structure at the bottom of the mounting groove and the limiting structure in the groove structure. Otherwise, it will take multiple attempts and hand feel to accurately and correctly install the sewage bucket on the main structure, which is cumbersome and greatly affects the user experience.

[0004] At the same time, the restricted space above and below the installation slot not only makes it inconvenient to install the sewage bucket, but also limits the volume expansion of the sewage bucket, or limits the liquid storage capacity of the sewage bucket, which is not conducive to improving the continuous operation capacity of the floor scrubber. Summary of the invention

[0005] The purpose of the present application is to provide a cleaning device that can simplify the alignment process and facilitate the assembly of a liquid storage barrel.

[0006] To achieve the above-mentioned purpose, the present application provides a cleaning device on the one hand, which includes at least a main structure, wherein the main structure includes a fuselage, a liquid storage barrel and a first mounting platform supporting the liquid storage barrel, the first mounting platform is arranged on the fuselage and extends in a direction away from the fuselage; the bottom of the liquid storage barrel has a supporting portion, and the supporting portion is surrounded to form a matching groove; the first mounting platform is embedded in the matching groove, the first mounting platform has a first top facing the liquid storage barrel, a first bottom opposite to the first top, and a first outer wall surface connected between the first top and the first bottom, along the length direction of the liquid storage barrel, the upper edge of the first outer wall surface is not lower than the bottom surface of the supporting portion and the bottom surface of the supporting portion forms at least a part of the bottom surface of the main structure.

[0007] To achieve the above-mentioned purpose, the present application also provides a cleaning device on the other hand, which includes at least a main structure, wherein the main structure has a liquid storage barrel and a first mounting platform supporting the liquid storage barrel; the bottom of the liquid storage barrel has a supporting portion extending downward and suspended around the outer side of the first mounting platform, and the bottom surface of the supporting portion at least forms a part of the bottom surface of the main structure.

[0008] To achieve the above-mentioned purpose, the present application further provides a cleaning device, which comprises at least a main structure and a floor brush; the main structure comprises a fuselage, a liquid storage barrel and a first mounting platform supporting the liquid storage barrel, the bottom end of the fuselage is connected to the floor brush, the first mounting platform is arranged on the fuselage and extends in a direction away from the fuselage, the first mounting platform has a first top supporting the liquid storage barrel, a first bottom opposite to the first top and a first outer wall surface connected between the first top and the first bottom; the liquid storage barrel has a supporting portion, and the supporting portion is surrounded to form a matching groove; when the liquid storage barrel is fixed on the first mounting platform, the first mounting platform is embedded in the matching groove, and the first outer wall surface is blocked by the supporting portion.

[0009] It can be seen that the technical solution provided by the present application is that the first mounting platform is embedded in the matching groove of the liquid storage barrel to achieve docking and stable support between the liquid storage barrel and the first mounting platform. This design allows the liquid storage barrel to be conveniently installed on the first mounting platform according to the matching relationship between the matching groove and the first mounting platform, thereby simplifying the user's installation process and improving the accuracy and efficiency of the operation. At the same time, the upper edge of the first outer wall surface is not lower than the bottom surface of the support portion, that is, the position where the support portion extends downward at least exceeds the upper edge of the first outer wall surface, so that the support portion can at least partially block the first outer wall surface, that is, the support portion can at least partially block the first mounting platform, and the design scheme can also cleverly transfer the joining line between the first mounting platform and the liquid storage barrel from the side of the cleaning device to the bottom of the device, that is, the position that is out of sight in the normal use state, effectively hiding the joining line between the liquid storage barrel and the first mounting platform, visually forming the effect of the first mounting platform being invisible, and further enhancing the appearance integrity and aesthetics of the cleaning device.

[0010] Furthermore, the upper edge of the first outer wall surface is not lower than the bottom surface of the support portion, which means that the liquid storage barrel is partially located below the first top of the first mounting platform and is suspended on the outer periphery of the first mounting platform to form a support portion. When the support portion is a hollow structure and is connected to the water storage space in the liquid storage barrel, the corresponding water storage space of the liquid storage barrel can also be extended downward from the top surface of the first mounting platform to expand the depth of the liquid storage barrel, so that the liquid position when the water in the liquid storage barrel is full is as far away from the top of the liquid storage barrel as possible, thereby avoiding the probability of water vapor being sucked into the internal motor by the negative pressure airflow, while increasing the volume of the liquid storage barrel and improving the continuous operation ability of the floor scrubber.

[0030] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship between a unit or feature as shown in the accompanying drawings relative to another unit or feature for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein are interpreted accordingly.

[0031] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] As people's living standards improve, more and more families are beginning to use various cleaning equipment, such as floor scrubbers, sweeping robots and other equipment to reduce labor intensity and improve the quality of life. Take a floor scrubber as an example. The floor scrubber provides clean water to the roller brush through a cleaning liquid barrel to help the roller brush dissolve and clean the stains on the ground. At the same time, the wastewater generated is pumped into the wastewater barrel through the wastewater recovery pipe, forming a continuous cleaning cycle, thereby efficiently completing the cleaning work.

[0033] In the design of the floor scrubber, the connection between the sewage bucket 300 and the main structure 100 is based on a detachable structure to achieve rapid dumping and cleaning of the dirt in the sewage bucket 300. Fig.18 As shown, the main structure 100 of the floor scrubber in the related art has a liquid storage tank, including a cleaning liquid tank 400 located at the top and a sewage tank 300 located at the bottom. Among them, the main structure 100 is provided with mounting grooves for accommodating the sewage tank 300 and the cleaning liquid tank 400, respectively. Both mounting grooves are recessed inwardly from the outer side of the main structure 100, and the sewage tank 300 and the cleaning liquid tank 400 are respectively embedded in the main structure 100 through the corresponding mounting grooves, so that the mounting grooves form a semi-enclosed connection with the sewage tank 300 and the cleaning liquid tank 400.

[0034] In actual use, taking the sewage bucket 300 as an example, when installing the sewage bucket 300, the sewage bucket 300 needs to first connect the sewage inlet at the bottom of the sewage bucket 300 with the matching interface at the bottom of the installation groove before it can be accurately installed in the installation groove, and the bottom of the installation groove is the installation platform. The side walls, top surface and bottom surface of the sewage bucket installation groove surround part of the outer surface of the sewage bucket 300, and the side walls of the sewage bucket installation groove extend upward around the bottom surface to form a concave groove structure. The bottom of the sewage bucket is embedded in the groove structure. The top surface of the side wall located at the bottom of the installation groove and extending around the fuselage is higher than the bottom surface of the sewage bucket. This part of the side wall higher than the bottom surface of the installation groove can prevent the sewage dripping from the sewage bucket from flowing out of the groove structure, but it also causes the bottom of the sewage bucket to first cross the obstruction of the side wall and enter the groove structure when installing. The above-mentioned groove structure is set on the installation platform. When the sewage bucket 300 is initially placed in the installation groove, due to the obstruction of the side wall of the groove structure, the sewage bucket 300 needs to tilt over the obstructing side wall and enter the groove structure of the installation platform. The bottom of the sewage bucket extends into the groove structure of the installation platform before other parts and contacts its bottom surface. Because the sewage bucket 300 tilts and extends into the groove structure, a part of the bottom of the sewage bucket first makes partial contact with the bottom surface of the installation platform to achieve point support, and then rotates at this support point, so that the entire bottom of the sewage bucket is completely embedded in the groove structure of the installation platform. In order to ensure that the sewage bucket 300 is installed in the right position and does not cause the sewage inlet and the matching port to not be fully connected due to rotation or deflection, resulting in sewage leakage into the groove space, generally, a convex block or a further concave groove is set in the groove space of the installation platform as a limit for the bottom of the sewage bucket 300 during rotation. The matching clearance between the bottom of the sewage bucket 300 and the matching limiting structure in the groove of the installation platform will be very small, thereby avoiding the sewage bucket from being installed in the wrong position and achieving precise installation. Because the sewage bucket 300 is embedded in the main structure 100, the side walls, top surface and bottom surface of the installation groove surround part of the outer surface of the sewage bucket 300, which will block the position of the sewage inlet and the matching interface and the limiting structure that needs to cooperate with each other. In other words, the sewage inlet at the bottom of the sewage bucket 300 and the matching interface on the main structure 100, as well as the limiting structure that needs to be precisely docked, are all located in a position that is invisible to the user during installation. In addition, because the sewage bucket 300 is embedded in the main structure 100, the top surface and bottom surface of the installation groove also surround the sewage bucket 300, limiting the adjustment space of the sewage tank 300 when it is installed. This also requires the user to adjust the upper and lower positions and left and right positions of the sewage bucket in the installation groove for many times and try to rely on the feel to accurately and correctly install the sewage bucket 300 on the main structure 100, so as to avoid the decrease in suction and sewage leakage caused by the inaccurate docking of the sewage inlet and the matching interface. The operation is cumbersome and greatly affects the user's experience.

[0035] At the same time, the above-mentioned sewage bucket 300 is embedded in the main structure 100, and the upper wall and the lower wall of the installation groove surround the sewage bucket 300. Obviously, this design blocks the top or bottom of the sewage bucket 300 from extending to the outside of the installation groove along the length direction of the sewage bucket 300, that is, it limits the volume expansion of the sewage bucket 300, thereby limiting the liquid storage depth of the sewage bucket 300, which is not conducive to improving the continuous operation capacity of the floor scrubber. In addition, when the sewage bucket 300 is installed in the installation groove, the junction line between the bottom of the sewage bucket 300 and the lower wall of the installation groove is located on the side of the whole, thereby affecting the overall aesthetics of the floor scrubber.

[0036] To this end, the present application redesigns the matching structure between the bottom of the liquid storage barrel, especially the sewage barrel 300, and the mounting platform, so as to simplify the alignment process, facilitate the assembly of the liquid storage barrel, expand the volume of the liquid storage barrel and improve the overall aesthetics of the cleaning equipment. Specifically, by forming a groove shape that matches the mounting platform at the bottom of the sewage barrel 300, during assembly, the mounting platform on the main structure 100 is embedded in the groove at the bottom of the sewage barrel 300. In this way, the sewage barrel 300 can be conveniently installed on the first mounting platform based on the matching relationship between the groove and the mounting platform, thereby simplifying the user's installation process and improving the accuracy and efficiency of the operation. Furthermore, after assembly, the bottom of the sewage bucket 300 is suspended on the periphery of the mounting platform, and is not limited by the mounting groove space formed by the mounting platform and the body 110 of the main structure 100, so that the bottom of the sewage bucket 300 can be extended downward along the length direction of the sewage bucket 300, increasing the depth of the sewage bucket 300, so that the liquid position of the sewage bucket 300 when full of water is as far away from the top of the sewage bucket 300 as possible, thereby avoiding the probability of water vapor being sucked into the internal motor by the negative pressure airflow, and at the same time increasing the volume of the sewage bucket 300, and improving the continuous operation capacity of the floor scrubber. At the same time, this structural design can also hide the mounting platform, and transfer the junction line between the sewage bucket 300 and the mounting platform to the bottom, that is, in an invisible area during normal use, so as to hide the junction line between the sewage bucket and the mounting platform and improve the aesthetics.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0038] The cleaning device provided in the present application may be a cleaning robot with cleaning functions such as floor washing, sweeping, and mopping. The cleaning device can automatically move on the surface to be cleaned to clean the surface to be cleaned. Of course, the cleaning device may also be a handheld floor washer with cleaning functions such as floor washing, sweeping, and mopping. The user pushes the cleaning device to move on the surface to be cleaned by holding the cleaning device to clean the surface, which is not limited here.

[0039] Please also see Figures 1 to 3 In an achievable embodiment, the cleaning device may at least include a main structure 100. The main structure 100 includes a fuselage 110, a liquid storage barrel and a first mounting platform 120. The fuselage 110 is the main part of the cleaning device, and is mainly used to support and protect other components on the cleaning device. The first mounting platform 120 is arranged on the fuselage 110, and extends away from the fuselage 110 to form a suspension. In this embodiment, the first mounting platform 120 can extend from the fuselage 110 along a direction perpendicular to the main extension line 111 of the fuselage 110 and away from the fuselage 110 and be suspended. It should be pointed out that the fuselage 110 has a top and a bottom that are relatively arranged along its length direction, and the main extension line 111 refers to a straight line connecting the top of the fuselage 110 with the bottom of the fuselage 110.

[0040] In a feasible implementation, the body 110 is connected to the floor brush 200 via a pivot member, and a handle is provided at the top of the body 110 for the user to hold. The user holds the handle to push the main structure 100 and the floor brush 200 to move.

[0041] In actual application, the main structure 100 can be pivoted at a certain angle relative to the floor brush 200, so that the cleaning device can more easily clean under furniture or in narrow spaces, that is, the main structure 100 can be tilted or even laid flat to meet the cleaning needs of different heights. In addition, it can also meet the needs of users of different heights, allowing users to use the floor scrubber more flexibly and conveniently without bending or squatting to operate easily. At the same time, this design also helps to reduce the physical burden of users during the cleaning process.

[0042] Among them, the first mounting platform 120 is used to cooperate with the bottom of the liquid storage barrel to dock and support the liquid storage barrel. Specifically, the first mounting platform 120 has a first top 122, a first bottom 123 and a first outer wall 124 facing the liquid storage barrel, the first bottom 123 is arranged opposite to the first top 122, the first outer wall 124 is connected between the first top 122 and the first bottom 123, and the first bottom 123 is suspended and arranged toward the floor brush, or in other words, the first mounting platform 120 is suspended as a whole above the floor brush except for the part connected to the main structure 100. The bottom of the liquid storage barrel has a support portion 310, and the support portion 310 is surrounded on a plane intersecting the length direction of the liquid storage barrel to form a matching groove 311, and the support portion 310 has a notch 312 facing the outer wall direction of the liquid storage barrel. For the convenience of description, this application defines the bottom surface of the support portion 310 as the first bottom surface 313. When the liquid storage barrel is installed on the main structure 100, the first installation platform 120 can be inserted into the matching groove 311 through the notch 312. Along the length direction of the liquid storage barrel, the upper edge 1242 of the first outer wall surface 124 is not lower than the first bottom surface 313, and the support portion 310 at least partially surrounds the outer side surface of the first installation platform 120. When the lower edge 1241 of the first outer wall surface 124 is not lower than the first bottom surface 313, the support portion 310 at least partially surrounds the outer side surface of the first installation platform 120. Please note that the support portion 310 surrounding the outer side surface of the first installation platform 120 can be a U-shaped structure formed by continuous extension, or the support portion 310 can have a disconnected area to form a shape surrounding the first installation platform 120.

[0043] In another feasible embodiment, the support portion at the bottom of the liquid storage barrel is provided with a matching groove on a plane intersecting the length direction of the liquid storage barrel but without a notch, so that Figure 6 The mutually perpendicular X-axis and Y-axis are used as references, and the support portion is adjacent to the main structure 100 and along Figure 6 The portion extending perpendicular to both the X-axis and the Y-axis is embedded in the corresponding groove on the top of the first mounting platform, thereby achieving a limiting effect on the liquid storage barrel. The support portion can be a hollow structure connected to the space inside the liquid storage barrel, or a solid structure.

[0044] In practical applications, the liquid storage barrel can be used as a sewage barrel 300 or as a cleaning liquid barrel 400. When the liquid storage barrel is used as a cleaning liquid barrel 400, the liquid storage barrel provides liquid to the floor brush 200 for cleaning. The bottom surface of the first mounting platform 120 is arranged toward the floor brush. When the liquid storage barrel is used as a sewage barrel 300, the sewage barrel 300 is used to collect and contain dirt generated during the cleaning process.

[0045] It is worth mentioning that the present application achieves docking and stable support between the liquid storage barrel and the first mounting platform 120 by embedding the first mounting platform 120 into the matching groove 311 at the bottom of the liquid storage barrel. This design allows the liquid storage barrel to be conveniently installed on the first mounting platform 120 based on the matching relationship between the matching groove 311 and the first mounting platform 120, thereby simplifying the user's installation process and improving the accuracy and efficiency of the operation. At the same time, the upper edge 1242 of the first outer wall 124 is not lower than the first bottom surface 313, and the support portion 310 at least partially blocks the first outer wall 124 of the first mounting platform 120. When the lower edge 1241 of the first outer wall 124 is not lower than the first bottom surface 313 of the support portion 310, that is, the downward extension position of the support portion 310 exceeds the lower edge 1241 of the first outer wall 124, so that the support portion 310 can block the first outer wall 124, that is, the support portion 310 can block the first mounting platform 120, and the design scheme can also cleverly transfer the joining line between the first mounting platform 120 and the liquid storage barrel from the side of the cleaning equipment to the bottom of the equipment, that is, a position that is out of sight under normal use, effectively hiding the joining line between the liquid storage barrel and the first mounting platform 120, visually forming a stealth effect of the first mounting platform, and further enhancing the appearance integrity and aesthetics of the cleaning equipment.

[0046] Furthermore, it is understandable that the liquid storage barrel is partially located below the first top portion 122 of the first mounting platform 120, and the water storage space of the corresponding liquid storage barrel can also be extended downward from the top surface of the first mounting platform 120 to increase the depth of the liquid storage barrel. Figure 4 As shown, in an achievable implementation, the support portion 310 can be made into a hollow structure, and the internal space of the support portion 310 can be used as a part of the liquid storage space in the liquid storage barrel to accommodate fluid substances (such as dirt or liquid). In other words, the liquid storage space in the liquid storage barrel can be partially extended downward by the support portion 310, so that the liquid position in the solution barrel is as far away from the top of the solution barrel as possible when the water in the solution barrel is full, thereby avoiding the probability of water vapor being sucked into the internal motor by the negative pressure airflow, and also increasing the ability to continue working.

[0047] In another optional embodiment, the support portion 310 may be made into a solid structure to increase the strength of the support portion 310 and improve the support stability of the support portion 310 on the liquid storage barrel.

[0048] In practical applications, the support portion 310 can be a part of the liquid storage barrel extending downward, and the support portion 310 is designed as an integral part with the liquid storage barrel. Of course, the support portion 310 can also be designed separately from the liquid storage barrel, and then connected to the bottom of the liquid storage barrel by welding, bonding or hot melting, etc., and this application does not make specific limitations on this.

[0049] In a feasible implementation, the support portion 310 can extend along the periphery of the liquid storage barrel, and the outer sidewall of the support portion 310 serves as a part of the outer sidewall of the liquid storage barrel and smoothly connects. In other words, the outer surface of the support portion 310 is integrated with the outer surface of the liquid storage barrel and smoothly transitions, so that the visual appeal of the product can be improved without sacrificing structural stability.

[0050] Of course, in another optional embodiment, there may be a certain degree of step difference between the outer wall of the support portion 310 and the outer wall of the liquid storage barrel, that is, the outer wall of the support portion 310 may be recessed inward or expanded outward from the outer wall of the liquid storage barrel.

[0051] In view of the fact that the liquid storage barrel needs to be disassembled from the main structure 100 for use regardless of whether it is used as a sewage barrel or a cleaning liquid barrel, in order to prevent the liquid storage barrel from tipping over when placed independently on the ground, in a feasible embodiment, the bottom surface of the support portion 310 is perpendicular to the length direction of the liquid storage barrel. In other words, the bottom surface of the support portion 310 is used as a plane, and the bottom surface of the liquid storage barrel forms a 90-degree angle with the length direction of the liquid storage barrel, so that the liquid storage barrel can stand stably on a horizontal plane (such as the ground or the surface of an object, etc.) through the bottom surface of the support portion 310, thereby preventing the liquid storage barrel from tipping over.

[0052] Ginseng Figure 3 as well as Figure 8 As shown, in a feasible implementation, the support portion 310 protrudes downward from the bottom of the liquid storage barrel to form a U-shaped structure, and the U-shaped support portion 310 surrounds and covers the first outer wall surface 124 of the first mounting platform 120 .

[0053] In a feasible embodiment, the support part 310 is suspended on the periphery of the first mounting platform 120. That is to say, the first bottom surface 313 of the support part 310 is suspended without contacting other surfaces, that is, the support part 310 is suspended as a suspended part around the first outer wall surface 124 of the first mounting platform 120, so that the first bottom surface 313 of the support part 310 can form a visual effect of the bottom surface of the main structure 100, that is, the first bottom 123 of the first mounting platform 120 and the first bottom surface 313 of the support part 310 together form the bottom surface of the main structure, and the first bottom surface 313 of the support part is located outside the bottom of the first mounting platform 120. Among them, the suspended part can be a hollow structure to communicate with the liquid storage space of the liquid storage barrel to expand the liquid storage capacity.

[0054] In another optional embodiment, the support portion 310 may also protrude downward from the bottom of the liquid storage barrel to form other shapes, such as a C shape, a V shape, etc. Figures 4 to 7As shown, in an achievable embodiment, a first docking portion 121 is formed on the first mounting platform 120, and correspondingly, a second docking portion 3111 that docks with the first docking portion 121 is formed on the bottom and / or wall of the matching groove 311. During the process of installing the liquid storage barrel to the main structure 100, the mating gap between the second docking portion 3111 and the first docking portion 121 changes from large to small. In other words, during the initial docking of the second docking portion 3111 and the first docking portion 121, as shown in FIG. Figure 4 and Figure 5 As shown, the mating gap between the second docking portion 3111 and the first docking portion 121 is relatively large, so that the user can insert the second docking portion 3111 into the first docking portion 121 to complete the preliminary docking without being fully aligned; on the basis of the above, when the second docking portion 3111 is further docked with the first docking portion 121, as shown in FIG. Figure 6 and Figure 7 As shown, the matching gap between the second docking portion 3111 and the first docking portion 121 is small, so that the liquid storage barrel can be accurately assembled on the first mounting platform 120 under the matching guidance of the second docking portion 3111 and the first docking portion 121. In this way, the installation of the liquid storage barrel can be completed even when it is not fully aligned, blind insertion installation is achieved, and the alignment process is simplified, so as to reduce the user's attention and physical operation difficulty during the installation process, and improve the user experience.

[0055] Regarding the specific structure of the first docking portion 121 and the second docking portion 3111 , the present application provides three achievable embodiments below for reference.

[0056] Embodiment 1: Figure 4 and Figure 5 As shown, the first docking portion 121 can be constructed as a groove structure, and the second docking portion 3111 can be constructed as a protruding structure. Specifically, the groove structure has a limiting section 1211 and a guiding section 1212 that are interconnected, and the gap formed by the guiding section 1212 is at least partially larger than the gap formed by the limiting section 1211, and when the liquid storage barrel is installed on the main structure 100, the second docking portion 3111 passes through the guiding section 1212 and the limiting section 1211 in sequence.

[0057] Embodiment 2: The first docking portion 121 may be configured as a protruding structure, and the second docking portion 3111 may be configured as a slot structure. Specifically, the slot structure has a limiting section 1211 and a guiding section 1212 that are interconnected, the gap formed by the guiding section 1212 is at least partially larger than the gap formed by the limiting section 1211, and when the liquid storage barrel is installed on the main structure 100, the second docking portion 3111 passes through the guiding section 1212 and the limiting section 1211 in sequence.

[0058] Embodiment three: One of the first docking portion 121 and the second docking portion 3111 is an arc-shaped claw or an arc-shaped groove, and the other is a laterally extending convex column. During the installation of the liquid storage barrel on the main structure 100, the convex column can easily enter the arc-shaped claw or the arc-shaped groove through the arc-shaped claw or the arc-shaped groove, and abut against the inner bottom surface of the arc-shaped claw or the arc-shaped groove, and the sewage barrel can be rotated with the mating abutting part as the rotation axis, thereby allowing the liquid storage barrel to be quickly installed even when it is not completely aligned.

[0059] Take the first docking portion 121 in the first embodiment as a groove structure, the second docking portion 3111 as a protruding structure, and the first docking portion 121 having a limiting section 1211 and a guiding section 1212 that are interconnected as an example. In a feasible implementation, the protruding structure extends along the length direction of the liquid storage barrel to form a convex strip shape, the first docking portion 121 extends downward from the top surface of the first mounting platform 120, and the guiding section 1212 is located above the limiting section 1211. For ease of description, the side of the guiding section 1212 away from the fuselage 110 is defined as a guiding surface 12121, and the side surface of the limiting section 1211 connected to the guiding surface 12121 is abutting surface 12111, and the guiding surface 12121 and the abutting surface 12111 are connected through a transition surface 12122. The guide surface 12121 expands outward while extending toward the top of the fuselage 110, that is, the opening range of the guide section 1212 is increased, so that the gap formed by the guide section 1212 is at least partially larger than the gap formed by the limiting section 1211, so that the user can insert the second docking portion 3111 into the first docking portion 121 without being fully aligned, which facilitates the assembly operation. The guide surface 12121 can be an inclined surface extending straight at a certain angle, or an inclined surface with an arc-shaped curved surface. The abutting surface 12111 is a straight surface parallel to the extension direction of the raised structure, so that after the liquid storage barrel is installed in place, it fits with the raised structure away from the abutting surface 12111 to achieve limiting.

[0060] In practical applications, such as Figure 5 As shown, the guide section 1212 can increase the gap formed by the guide section 1212 only by expanding the guide surface 12121 outward while extending toward the top of the fuselage 110. Of course, the guide section 1212 can also have two guide surfaces 12121 arranged opposite to each other, and the two guide surfaces 12121 expand outward while extending toward the top of the fuselage 110, thereby increasing the gap formed by the guide section 1212, and the present application does not make any specific limitation on this.

[0061] The first docking portion 121 constructed as a groove structure can be connected only to the first top portion 122 , and accordingly, the second docking portion 3111 extends downward from the groove bottom of the matching groove 311 , and the second docking portion 3111 is not connected to the groove wall of the matching groove 311 .

[0062] Of course, the first docking portion 121 constructed as a groove body structure can also be connected to the first top 122 and the first outer wall 124 at the same time. Correspondingly, the second docking portion 3111 can be connected to the groove bottom and groove wall of the matching groove 311 at the same time. In this way, the connection strength between the second docking portion 3111 and the liquid storage barrel can be enhanced, the stability of the second docking portion 3111 can be improved, and the possibility of bending and damage of the second docking portion 3111 can be reduced.

[0063] The first docking portion 121 and the second docking portion 3111 may each have one. Of course, the first docking portion 121 and the second docking portion 3111 may each have two.

[0064] like Figure 8 As shown, in an achievable embodiment, there are two first docking parts 121 and two second docking parts 3111. The two first docking parts 121 are respectively located on opposite sides of the first mounting platform 120 along a direction perpendicular to the main extension line 111, that is, each first docking part 121 is simultaneously connected to the top surface of the first mounting platform 120 and the side wall of the first mounting platform 120. The two second docking parts 3111 are respectively located on opposite sides of the groove wall of the matching groove 311. Moreover, the two first docking parts 121 and the two second docking parts 3111 correspond one to one. In this way, when the liquid storage barrel is installed to the first mounting platform 120, the two second docking parts 3111 are respectively inserted into the two first docking parts 121, thereby sharing the force, reducing the force wear and fracture, and improving the service life.

[0065] Please also see Figure 2 and Figure 7As shown, in an achievable embodiment, the first top 122 is constructed as an inclined surface structure inclined downward from the fuselage 110, and the first top 122 can be a straight inclined surface structure, a curved inclined surface structure, or a straight inclined surface structure with a partial stepped protrusion. The bottom of the matching groove 311 matches the top surface of the first mounting platform 120, that is, the bottom of the matching groove 311 is also constructed as an inclined surface structure, and the slope of the bottom of the matching groove 311 is substantially the same as the slope of the top surface of the first mounting platform 120. In this way, when the liquid storage barrel is installed on the first mounting platform 120, the first mounting platform 120 is embedded in the matching groove 311 through the notch 312, and the bottom of the matching groove 311 can be in contact with the top surface of the first mounting platform 120 to support the liquid storage barrel. At the same time, the setting of the first top 122 as an inclined surface structure also facilitates the rotational installation of the liquid storage barrel with the contact surface of the two as the rotation support point during the process of the groove bottom and the first top 122 being in contact.

[0066] Furthermore, it can be understood that since the first top portion 122 is tilted downward from the body 110, when the liquid storage barrel is installed on the first top portion 122, under the action of the liquid storage barrel's own gravity, the liquid storage barrel has a tendency to slide downward along the first top portion 122, thereby driving the second docking portion 3111 to slide downward along the tilting direction of the first top portion 122 and cooperate with the abutting surface 12111, so as to reduce the possibility of the liquid storage barrel being able to shake relative to the main structure 100 due to the matching gap between the second docking portion 3111 and the limiting section 1211, thereby improving the assembly stability of the liquid storage barrel on the main structure 100.

[0067] To further improve the installation stability of the liquid storage tank, please refer to Figure 5 and Figure 7 As shown, in a feasible implementation, the inner side wall of the support portion 310 matches the first outer wall surface 124, that is, the inner side wall of the support portion 310 matches the shape and size of the first outer wall surface 124. In this way, when the first mounting platform 120 passes through the notch 312 and is embedded in the matching groove 311, the inner side wall of the support portion 310 matches the first outer wall surface 124. In this way, the second docking portion 3111 and the abutting surface 12111 abut and cooperate with each other, and the inner side wall of the support portion 310 and the first outer wall surface 124 cooperate together, so that the lower part of the liquid storage barrel can be more firmly fixed on the first mounting platform 120.

[0068] In this embodiment, when the liquid storage barrel needs to be installed on the first installation platform 120, the user can first obliquely insert the second docking portion 3111 of the liquid storage barrel into the guide section 1212, and then rotate the liquid storage barrel toward the side of the fuselage 110 with the first installation platform 120 as the rotation axis. During the rotation process, one side of the second docking portion 3111 rotates and moves along the bent portion (i.e., the transition surface 12122) between the guide section 1212 and the limiting section 1211 and gradually inserts into the limiting section 1211. During the rotation process, the second docking portion 3111 maintains contact with the transition surface 12122 between the guide surface 12121 and the abutting surface 12111 until the second docking portion 3111 and the abutting surface 12111 are contacted, and the liquid storage barrel moves to the top of the first installation platform 120, and the upper part of the liquid storage barrel is detachably connected to the fuselage 110, thereby completely constraining the six degrees of freedom of the liquid storage barrel, and completing the installation operation.

[0069] Please see again Figure 2 As shown, in an achievable embodiment, the main structure 100 may further include a second mounting platform 130. The second mounting platform 130 extends from the fuselage 110 in a direction perpendicular to the main extension line 111 and in a direction away from the fuselage 110. The second mounting platform 130 is located above the first mounting platform 120, and the first mounting platform 120, the second mounting platform 130 and the fuselage 110 are jointly surrounded to form a first mounting groove 140 for accommodating the liquid storage barrel. In this embodiment, the top surface of the liquid storage barrel and the bottom surface of the second mounting platform 130 are both constructed as a plane structure. When the liquid storage barrel is installed in the first mounting groove 140, the top surface of the liquid storage barrel is parallel to and opposite to the bottom surface of the second mounting platform 130, and the top surface of the liquid storage barrel is a closed surface. In actual application, the top surface of the liquid storage barrel may be provided with convex points, and when the liquid storage barrel is installed in the first mounting groove 140, the liquid storage barrel may support the second mounting platform 130 through the convex points.

[0070] It is worth mentioning that the present application utilizes the top surface of the first mounting platform 120 to rotate around the rotation center, and the top surface of the liquid storage barrel is assembled to the main structure 100 in cooperation with the second mounting platform 130 by plane matching, so that the opening of the first mounting groove 140 does not need to be made too large compared to the liquid storage barrel, and it is also convenient for the liquid storage barrel to be installed to the first mounting groove 140, thereby effectively reducing the assembly gap between the top surface of the liquid storage barrel and the bottom surface of the second mounting platform 130, realizing small gap assembly, and improving the overall aesthetics of the cleaning base station. The distance between the top surface and the bottom surface of the first mounting groove 130 is smaller than the distance between the top surface and the bottom surface of the liquid storage barrel, that is, the distance between the top surface of the first mounting platform 120 and the bottom surface of the second mounting platform 130 is smaller than the distance between the top surface and the bottom surface of the liquid storage barrel.

[0071] Along the length direction of the liquid storage barrel, the bottom surface of the liquid storage barrel, or the bottom surface of the support portion 310 is lower than the bottom surface of the first mounting groove 130, ensuring that the height setting of the liquid storage barrel is not limited by the height inside the first mounting groove 130, thereby failing to expand the liquid storage capacity.

[0072] In the length direction of the liquid storage barrel, the projection area formed by the support portion 310 is larger than the projection area of ​​the first mounting platform 120, and the projection area of ​​the second mounting platform 130 is larger than the projection area of ​​the first mounting platform 120. The projection area formed by the first mounting platform 120 is a part of the projection area formed by the support portion 310, and the projection area formed by the first mounting platform 120 is a part of the projection area formed by the second mounting platform 130.

[0073] The gap between the top surface of the liquid storage barrel and the bottom surface of the second mounting platform 130 is no more than 2 mm. Preferably, the gap between the top surface of the liquid storage barrel and the bottom surface of the second mounting platform 130 is no more than 1 mm.

[0074] The liquid storage barrel can be used as a sewage barrel 300 or as a cleaning liquid barrel 400. However, considering that the sewage barrel 300 should be arranged close to the bottom of the body 110, the dirt absorbed by the floor brush 200 can be efficiently sucked into the sewage barrel 300. Therefore, the liquid storage barrel is preferably used as a sewage barrel 300.

[0075] In actual application, when the liquid storage bucket is used as a sewage bucket 300, a sewage inlet should be provided on the bottom of the groove 311, and a matching interface should be provided on the top surface of the first mounting platform 120. When the sewage bucket 300 is installed in the first mounting groove 140, the sewage inlet and the matching interface are sealed and connected through the soft rubber part 160, and the soft rubber part 160 surrounds the matching interface and protrudes from the first mounting platform 120. A concave area (such as a concave area) that fits the soft rubber part 160 is provided around the sewage inlet corresponding to the matching groove 311. Figure 8 As shown in the figure, the soft rubber part 160 is in interference contact with the top surface of the protruding first mounting platform, and the soft rubber part 160 can also be used as a part of the support liquid storage bucket in the recessed area. In this way, the dirt sucked from the floor brush 200 can flow into the sewage bucket 300 through the matching port and the sewage inlet for storage.

[0076] Please see again Figure 1 As shown, in an achievable embodiment, the cleaning device may further include a cleaning liquid barrel 400, which is used to contain liquid (clean water or cleaning liquid), and the liquid in the cleaning liquid barrel 400 flows to the floor brush 200 to dissolve stains and improve the cleaning effect. The cleaning liquid barrel 400 is connected to the body 110, and the cleaning liquid barrel 400 is located above the sewage barrel 300, so that the liquid in the cleaning liquid barrel 400 can flow out smoothly under the action of gravity.

[0077] Furthermore, the body 110 has a front side 112 and a back side 113 which are arranged back to back, and the front side 112 is located on a side of the body 110 adjacent to the floor brush 200, and the sewage bucket 300 and the cleaning liquid bucket 400 are located on the front side 112. In this way, when the user uses the cleaning device to clean the surface to be cleaned, the body 110 is tilted, the front side 112 is located above the body 110, and the back side 113 is located below the body 110. The sewage bucket 300 and the cleaning liquid bucket 400 are arranged on the front side 112, which can facilitate the user to observe the storage volume in the sewage bucket 300 and the cleaning liquid bucket 400, thereby improving the user experience. Moreover, compared with the related art in which the sewage bucket 300 and the cleaning liquid bucket 400 are located below the fuselage 110, the sewage bucket 300 and the cleaning liquid bucket 400 of the present application are located above the fuselage 110, and the fuselage 110 can provide support for the sewage bucket 300 and the cleaning liquid bucket 400, reduce the stress on the connection between the sewage bucket 300 and the cleaning liquid bucket 400 and the fuselage 110, reduce the possibility of damage, and increase the service life. After the sewage bucket 300 is installed in place, from the front 112 direction, the first bottom surface 313 of the sewage bucket 300 is suspended on the fuselage 110, and the sewage bucket 300 blocks the first installation platform 120 to prevent the first installation platform 120 from being exposed, that is, the first installation platform 120 is hidden inside the sewage bucket 300, and at the same time, the first bottom surface 313 of the sewage bucket 300 is arranged close to the bottom end of the main structure 100, so that the first bottom surface 313 of the sewage bucket 300 can form a bottom surface visual effect similar to the main structure 100.

[0078] In actual application, the second mounting platform 130 cooperates with the body 110 to form a second mounting groove 150, and the second mounting groove 150 is used to accommodate the cleaning liquid barrel 400. The top surface of the second mounting platform 130 may be provided with a water supply port, and when the cleaning liquid barrel 400 is installed in the second mounting groove 150, the cleaning liquid barrel 400 is sealed and connected to the water supply port, so that the liquid in the cleaning liquid barrel 400 can flow to the floor brush 200 through the water supply port.

[0079] Please also see Figure 2 and Fig. 9 As shown, in an achievable embodiment, the cleaning liquid barrel 400 is slidably connected to the body 110 through a dovetail groove structure, and a clamping structure is provided between the cleaning liquid barrel 400 and the body 110. In actual application, when the cleaning liquid barrel 400 needs to be installed in the second installation groove 150, the user can first slide the cleaning liquid barrel 400 from top to bottom through the corresponding dovetail groove structure until the cleaning liquid barrel 400 is sealed and connected to the water supply port, and the clamping structures between the cleaning liquid barrel 400 and the body 110 are clamped to each other, thereby completing the installation and fixation of the cleaning liquid barrel 400.

[0080] like Fig. 9 and Fig.10As shown, in an achievable embodiment, the cleaning liquid barrel 400 may include a first barrel body 410 and a first barrel cover 420. The first barrel cover 420 is detachably connected to the first barrel body 410. When the first barrel cover 420 is connected to the first barrel body 410, the first barrel cover 420 seals the opening of the first barrel body 410 to prevent the liquid in the first barrel body 410 from flowing out. When the first barrel cover 420 and the first barrel body 410 are separated, the user can fill water into the first barrel body 410 through the opening of the first barrel body 410.

[0081] In this embodiment, a drain valve 430 may be integrated on the first bucket cover 420. The cleaning liquid bucket 400 is used to be installed on the second mounting platform 130 in an inverted manner. When the cleaning liquid bucket 400 is invertedly installed on the second mounting platform 130, the drain valve 430 can be pushed open at the water supply port on the second mounting platform 130, so that the liquid in the cleaning liquid bucket 400 passes through the drain valve 430 and flows to the floor brush 200 through the water supply port on the second mounting platform 130. In addition, compared with integrating the drain valve 430 on the first barrel body 410, the drain valve 430 of the present application is integrated on the first bucket cover 420, which can reduce the processing difficulty of the cleaning liquid bucket 400. At the same time, when water is poured into the first barrel body 410, the liquid in the first barrel body 410 can be prevented from accidentally flowing out through the drain valve 430, thereby improving the user experience.

[0082] Furthermore, a one-way blocking structure 440 may be connected to the first barrel body 410 or the first barrel cover 420. The one-way blocking structure 440 is used to connect the air in the cleaning liquid barrel 400 with the external environment to balance the pressure difference between the inside and the outside, and at the same time prevent the liquid in the cleaning liquid barrel 400 from flowing to the outside through the one-way blocking structure 440. In practical applications, the specific structure of the one-way blocking structure 440 can refer to the duckbill valve structure, and this application will not repeat it here.

[0083] Preferably, the one-way blocking structure 440 should be provided on the first barrel body 410, and the one-way blocking structure 440 is located at one end of the first barrel body 410 away from the first barrel cover 420. In this way, when the cleaning liquid barrel 400 is invertedly installed on the second installation platform 130, the one-way blocking structure 440 is located above the cleaning liquid barrel 400. As the liquid in the cleaning liquid barrel 400 gradually flows out, the liquid in the cleaning liquid barrel 400 is located below the one-way blocking structure 440 most of the time, which can reduce the continuous pressure of the liquid in the cleaning liquid barrel 400 on the one-way blocking structure 440 and improve the service life of the one-way blocking structure 440.

[0084] Considering that when the cleaning device is in use, the user needs to hold the top of the cleaning device to push the cleaning device to move. In order to reduce the force that the user needs to apply to the cleaning device, please refer to Figure 1 and Figure 2As shown, in an achievable embodiment, the cleaning device further includes a power source 500. The power source 500 is used to extract air from the sewage bucket 300 to form a negative pressure in the sewage bucket 300, so that the dirt at the floor brush 200 is sucked into the sewage bucket 300 under the action of internal and external pressures. The power source 500 is located at the rear side of the liquid storage bucket, installed on the back side 113 of the body 110, and located at the rear side of the sewage bucket 300 and the cleaning liquid bucket 400, and the power source 500 is arranged adjacent to the floor brush 200, and more than half of the power source 500 is located between the second mounting platform 130 and the floor brush 200, so that the center of gravity of the power source 500 is arranged adjacent to the floor brush 200. In other words, when the cleaning device is in use, the center of gravity of the power source 500 is set close to the bottom of the cleaning device, thereby moving the overall center of gravity of the cleaning device downward. In this way, when the user holds the top of the cleaning device and pushes the cleaning device, the force of the cleaning device on the user's hand can be greatly reduced. In other words, the user can use very little force to push the cleaning device to achieve the movement of the cleaning device, thereby improving the user's grip feel, facilitating the user's operation, and improving the user's experience.

[0085] In practical applications, the power source 500 may be composed of a motor and an impeller. The motor drives the impeller to rotate at high speed. When the impeller rotates at high speed, the impeller can absorb air and discharge the air to the outside to form a negative pressure. The power source 500 can be used as a separate component, integrally installed in the cleaning device, or integrally removed from the cleaning device to facilitate subsequent maintenance and replacement. In another optional embodiment, the power source 500 can also be integrated into the cleaning device as a part of the cleaning device that cannot or is not easily removed.

[0086] In order to reduce the possibility of dirt and / or water vapor in the sewage bucket 300 being absorbed into the power source 500, the service life of the power source 500 is increased. Fig.11 and Fig.12 As shown, in an achievable implementation, the air inlet of the power source 500 can be arranged toward the bottom of the body 110. That is, the power source 500 is arranged upside down, so that when the cleaning device is in use, the air inlet of the power source 500 faces downward, and under the influence of gravity, it can reduce the water droplets condensed by dirt and / or water vapor from falling directly into the motor and causing damage to the motor.

[0087] In this embodiment, when the sewage bucket 300 is installed in the first installation groove 140, the air inlet of the power source 500 is connected to the negative pressure port of the sewage bucket 300 through the air inlet duct 600, and the air inlet duct 600 is formed between the air inlet 510 of the power source 500 and the negative pressure port 370 of the sewage bucket 300, and is partially arranged in the fuselage 110. The air inlet 510 of the power source 500 is located below the negative pressure port 370 of the sewage bucket 300 to achieve a staggered arrangement. At the same time, in conjunction with the front-to-back layout design of the power source 500 and the sewage bucket 300, the length and number of bends of the air inlet duct 600 are increased as much as possible, the water vapor separation effect is improved, and the possibility of dirt and / or water vapor being absorbed into the power source 500 is further reduced.

[0088] In an optional embodiment, the air inlet duct 600 can be connected between the air inlet 510 of the power source 500 and the negative pressure port 370 of the sewage bucket 300 by using a pipeline design such as a hose or a hard pipe.

[0089] In another optional embodiment, the air inlet duct 600 may also be formed by a channel completely surrounded by the inner wall of the fuselage 110 , and the air inlet duct 600 is formed during the molding process of the fuselage 110 .

[0090] In another optional embodiment, the air inlet duct 600 may be partially formed by a channel surrounded by the inner wall of the fuselage 110, and the other part may be formed by a pipeline design or surrounded by the outer shell structure of the power source 500. For details, please refer to Figures 5 to 11 As shown, the air inlet duct 600 may include a first duct 610 and a second duct 620. The first duct 610 is formed in the body 110, and a first vent 611 for communicating with the negative pressure port 370 of the sewage bucket 300 is formed on the front 112 located in the first mounting groove 140, and a second vent 612 is formed on the back 113. The second duct 620 is constructed as an L-shaped structure, and the second vent 612 is communicated with the air inlet 510 of the power source 500 through the second duct 620. The L-shaped second duct 620 includes a horizontal section and a vertical section, and the air inlet 510 of the power source 500 is communicated with the top of the vertical section, ensuring that the water droplets condensed in the duct are gathered on the bottom surface of the horizontal section due to gravity and cannot pass through the vertical section to enter the inside of the power source due to negative pressure suction and cause damage. When the power source 500 is running, the power source 500 absorbs air in the sewage bucket 300 through the second air duct 620, the first air duct 610 and the negative pressure port 370 of the sewage bucket 300 in turn to form a negative pressure in the sewage bucket 300. At the same time, the total length of the air duct is increased to achieve water vapor separation and reduce the risk of water vapor directly entering the power source 500.

[0091] For the specific structure of the sewage bucket 300, please refer to Fig.13 and Fig.14As shown, the sewage bucket 300 includes a second barrel body 320 and a second barrel cover 330. The second barrel cover 330 is detachably connected to the second barrel body 320 and covers the opening of the second barrel body 320. A third air duct 630 is formed in the second barrel cover 330. The third air duct 630 extends upward from the opening of the second barrel body 320 along the length direction of the sewage bucket 300, and then extends in a direction substantially perpendicular to the length direction of the sewage bucket 300, so that the negative pressure port 370 of the sewage bucket 300 is formed on the side wall surface of the second barrel cover 330. When the sewage bucket 300 is installed in the first installation groove 140, the negative pressure port 370 is connected to the first air port 611, so that the air in the second barrel body 320 flows to the power source 500 through the third air duct 630, the first air duct 610 and the second air duct 620 in sequence. In this way, the number of bends of the air duct from the inside of the sewage bucket 300 to the air inlet of the power source 500 can be further increased, thereby further improving the water vapor separation effect and reducing the possibility of water vapor entering the power source 500.

[0092] In a feasible embodiment, a filter element 340 is detachably connected to the second barrel cover 330, and the plane where the filter element 340 is located is roughly parallel to the length direction of the sewage barrel 300, and the filter element 340 is arranged at the negative pressure port 370, specifically, it is arranged inside the negative pressure port 370 and adjacent to the first air duct 611, so as to filter the air flowing through the negative pressure port 370 to prevent water vapor and / or dirt from entering the first air duct 610.

[0093] In practical applications, the filter element 340 can be detachably connected to the negative pressure port 370 of the sewage bucket 300, so that the filter element 340 can be replaced without removing the second bucket cover 330, which is convenient for maintenance and replacement operations. The filter element 340 is disassembled and assembled along a length direction perpendicular to the sewage bucket 300. Among them, the filter element 340 can be made of HEPA or other components with filtering functions, which is not specifically limited in this application.

[0094] In order to further improve the separation effect of water vapor and dirt in the sewage bucket 300, please refer to Fig.12 As shown, in an achievable embodiment, the third air duct 630 has a first section and a second section, which are a horizontal section and a vertical section respectively, wherein the vertical section is substantially parallel to the length direction of the sewage bucket 300, and the horizontal section is substantially perpendicular to the length direction of the sewage bucket 300. The third air duct 630 is provided with a gas-liquid separation plate 640 in the horizontal section and adjacent to the vertical section. The gas-liquid separation plate 640 extends upward from the lower part of the inner wall of the horizontal section to a preset position, and the height of the preset position exceeds half the height of the filter element 340. In this way, when the air of the sewage bucket is extracted through the third air duct 630, the air in the sewage bucket 300 can flow to the downstream through the gap between the top of the gas-liquid separation plate 640 and the upper part of the horizontal section (see for details). Fig.12The arrow in the figure indicates the direction of the air flow), while the relatively heavy water vapor and / or dirt can be blocked by the gas-liquid separation plate 640, thereby achieving the effect of gas-liquid separation. The filter element 340 is arranged in the horizontal section, and the filter element 340 is arranged at the outlet of the third air duct horizontal section, and the gas-liquid separation plate 640 is arranged at the inlet opposite to the aforementioned outlet.

[0095] Furthermore, along the direction of water vapor flow in the horizontal section, the gas-liquid separation plate 640 is located upstream of the filter element 340. In other words, the air in the sewage bucket 300 that is sucked first passes over the gas-liquid separation plate 640 for gas-liquid separation, and then is filtered by the filter element 340, thereby reducing the probability of the filter element 340 being contaminated by water vapor and / or dirt, extending the service life of the filter element 340, reducing the user's use cost, and also reducing the probability of water vapor condensing into water droplets in the horizontal section of the third air duct.

[0096] Please also see Figure 2 , Fig.14 and Fig.15 As shown, in an achievable embodiment, the second bucket cover 330 is provided with a movable locking member 380, and the front side 112 of the body 110, that is, the front side in the first installation groove 140, is provided with a locking groove 114 matching the movable locking member 380, and the sewage bucket 300 is connected with the locking groove 114 through the movable locking member 380 to achieve a detachable connection with the body 110. Specifically, the movable locking member 380 may include a flip buckle plate 331 and a spring (not shown). Among them, the middle part of the flip buckle plate 331 is hinged with the second bucket cover 330, one end of the flip buckle plate 331 extends out of the side wall surface of the second bucket cover 330 and is provided with a buckle portion 3311 extending downward, or in other words, the movable locking member 380 has a buckle portion 3311 exposed to the side wall surface of the second bucket cover 330, and the other end of the flip buckle plate 331 is provided with an operating portion 3312. The spring abuts between the top surface of the flip buckle plate 331 near the buckle part 3311 and the second bucket cover 330, or the spring abuts between the bottom surface of the flip buckle plate 331 near the operating part 3312 and the second bucket cover 330, so as to drive the buckle part 3311 to flip downward. Among them, the movable lock fastener can have one, two or more, which is not specifically limited in this application. In this embodiment, a pair of buckle parts 3311 are arranged on both sides of the negative pressure port of the second bucket cover and are symmetrically arranged with the negative pressure port as the center.

[0097] In actual application, the top surface of the sewage bucket 300 is a closed surface and is perpendicular to the extension direction of the sewage bucket, that is, the top surface of the sewage bucket 300 is a plane. When the sewage bucket 300 needs to be installed in the first installation groove 140, the user first inserts the second docking portion 3111 of the sewage bucket 300 into the guide section 1212 at an angle, and then rotates the sewage bucket 300 toward the side of the fuselage 110 with the first installation platform 120 as the rotation axis. During the rotation process, one side of the second docking portion 3111 rotates and moves along the bent portion between the guide section 1212 and the limiting section 1211 and gradually inserts into the limiting section 1211. By allowing the sewage bucket 300 to sink a certain distance while rotating, it is ensured that the top surface of the sewage bucket will not be stuck and unable to rotate during the rotation process due to insufficient spacing with the bottom surface of the second installation platform 130. As the sewage bucket 300 moves into the first installation groove 140, the buckle portion 3311 is inserted into the locking groove 114 to achieve automatic buckling without user operation. When unlocking, the user presses the operating portion 3312 and the buckling portion 3311 flips upward to leave the buckled state.

[0098] The gap between the top surface of the sewage bucket 300 and the bottom surface of the second mounting platform 130 is no more than 2 mm, and they are parallel to each other. Preferably, the gap between the top surface of the sewage bucket 300 and the bottom surface of the second mounting platform 130 is no more than 1 mm.

[0099] After the power source 500 absorbs the air in the sewage bucket 300, it is also necessary to discharge the corresponding air. In order to avoid the air discharged by the power source 500 blowing directly to the user and causing discomfort to the user, please refer to Figure 2 , Fig.12 and Fig.14 As shown, in an achievable embodiment, the front face 112 in the first mounting groove 140 is formed with an exhaust port 1121, the exhaust port 1121 is located below the first air port 611, and the air outlet of the power source 500 is connected with the exhaust port 1121 through the air outlet duct 700. A spacer 360 is provided on the sewage bucket 300 or the front face 112 in the first mounting groove 140. When the sewage bucket 300 is installed in the first mounting groove 140, the spacer 360 is located between the sewage bucket 300 and the front face 112, so that an exhaust gap 350 is formed between the sewage bucket 300 and the front face 112, and the exhaust port 1121 is connected with the exhaust gap 350.

[0100] In this way, the air exhausted by the power source 500 can flow out from the exhaust port 1121 through the air outlet duct 700, and diffuse to the surroundings along the exhaust gap 350, so as to flow out from the assembly gap between the sewage bucket 300 and the main structure 100, thereby reducing the impact force of the air exhausted by the power source 500, and changing the flow direction of the air exhausted by the power source 500, so as to avoid causing discomfort to the user and improve the user experience. At the same time, when in use, the sewage bucket 300 can block the exhaust port 1121 to prevent the exhaust port 1121 from leaking out to improve the aesthetics of the cleaning equipment. In addition, the air flowing out of the exhaust port 1121 directly impacts the sewage bucket 300, and the sewage bucket 300 can also reduce the air power flowing out of the exhaust port 1121, further reducing the impact force of the air discharged by the power source 500.

[0101] In practical applications, when the spacer 360 is provided on the sewage bucket 300, the spacer 360 can be located on the side wall of the second barrel body 320. The spacer 360 can be designed as an integral part with the second barrel body 320, or it can be designed as a separate part and then connected by gluing, hot melting or screw connection, etc., and this application does not make specific restrictions on this. When the spacer 360 is provided on the front 112, the spacer 360 can be designed as an integral part with the fuselage 110, or it can be designed as a separate part and then connected by gluing, hot melting or screw connection, etc., and this application does not make specific restrictions on this.

[0102] For the specific structure of the floor brush 200, please refer to Fig.16 and Fig.17 As shown, in an achievable embodiment, the floor brush 200 may include a housing 210. The housing 210 is connected to the main structure 100, and the housing 210 has a sewage suction port 211, which is connected to the matching port on the main structure 100, and the housing 210 is installed with a roller brush 240 at the sewage suction port 211. When the sewage bucket 300 is installed in the first mounting groove 140, the sewage inlet at the bottom of the sewage bucket 300 is connected to the matching port, so that the sewage suction port 211 is connected to the sewage bucket 300. In this way, the negative pressure in the sewage bucket 300 can be transmitted to the sewage suction port 211 through the connection between the matching port and the sewage inlet, so that the dirt generated by the roller brush 240 during cleaning can be sucked by the sewage suction port 211 and flow into the sewage bucket 300. In actual applications, walking wheels 250 are usually installed on the housing 210 to assist the floor brush 200 in walking on the surface to be cleaned.

[0103] In an achievable embodiment, the floor brush 200 may further include a scraper bar water spray assembly 220. The scraper bar water spray assembly 220 is composed of a comb-tooth scraper bar and a water spray plate assembled together. When in use, the comb-tooth scraper bar abuts against the roller brush 240. As the roller brush 240 rotates, the comb-tooth scraper bar can scrape off the dirt on the roller brush 240 so that the dirt is sucked by the sewage suction port 211. The comb-tooth scraper bar can also straighten the hair or wire bundle entangled on the roller brush 240, so as to facilitate suction by the sewage suction port 211 and avoid the hair or wire bundle on the roller brush 240 from being entangled.

[0104] However, it is found that the roller brush 240 will be gradually worn during long-term use, which makes it impossible for the comb-tooth scraper bar to abut against the roller brush 240 to achieve the above function. In order to solve the above problem, in a feasible implementation, the scraper bar water spraying assembly 220 is hinged to the housing 210, the scraper bar water spraying assembly 220 is located above the sewage suction port 211, and an elastic member 260 is provided between the scraper bar water spraying assembly 220 and the housing 210, and the elastic member 260 is used to drive the scraper bar water spraying assembly 220 to abut against the roller brush 240. In this way, as the roller brush 240 gradually wears, the elastic member 260 can drive the scraper bar water spraying assembly 220 to always fit with the roller brush, thereby ensuring that the comb-tooth scraper bar of the scraper bar water spraying assembly 220 always abuts against the roller brush 240.

[0105] In practical applications, the two ends of the scraper water spray assembly 220 may be provided with rotating shafts respectively, and the scraper water spray assembly 220 is rotatably connected to the housing 210 through the rotating shafts at both ends. The elastic member 260 may be a spring, a rubber block or other components with elastic deformation ability.

[0106] In an achievable embodiment, the floor brush 200 may further include an elastic seal 230. The elastic seal 230 has elastic deformation capability and may be made of elastic materials such as rubber and silicone. The elastic seal 230 is connected to the housing 210, the elastic seal 230 is located above the sewage suction port 211, and the elastic seal 230 abuts against the bottom of the scraper bar water spray assembly 220. In this way, when the scraper bar water spray assembly 220 flips and floats relative to the housing 210, the elastic seal 230 always abuts against the bottom of the scraper bar water spray assembly 220, thereby always sealing the gap between the scraper bar water spray assembly 220 and the upper wall of the sewage suction port 211, thereby preventing dirt from entering the gap between the scraper bar water spray assembly 220 and the upper wall of the sewage suction port 211 to affect the flipping of the scraper bar water spray assembly 220, and preventing dirt from being hidden in the gap between the scraper bar water spray assembly 220 and the upper wall of the sewage suction port 211 to produce odor.

[0107] Based on the same inventive concept, the present application also provides a cleaning device, which includes at least a main structure 100, wherein the main structure 100 has a liquid storage barrel and a first mounting platform 120 supporting the liquid storage barrel. The bottom of the liquid storage barrel has a support portion 310 extending downward and suspended around the outer side of the first mounting platform, and the bottom surface of the support portion 310 forms at least a part of the bottom surface of the main structure 100.

[0108] In this embodiment, the support portion 310 is suspended around the outer side of the first mounting platform 120. That is, the bottom surface of the support portion 310 is suspended without contacting other surfaces, that is, the support portion 310 is suspended around the first outer wall surface 124 of the first mounting platform 120, so that the suspended portion can form a visual effect of "sharing the same bottom surface" with the main structure 100. Among them, the support portion 310 can be a hollow structure to communicate with the liquid storage space of the liquid storage barrel to expand the liquid storage capacity.

[0109] It should be pointed out that, regarding the specific structures of the main structure 100, the first mounting platform 120, the support portion 310 and the liquid storage tank, reference may be made to the contents described in the above-mentioned embodiments, and the present application will not repeat them here.

[0110] Based on the same inventive concept, the present application also provides a cleaning device, which at least includes a main structure 100 and a floor brush 200. The main structure 100 includes a body 110, a liquid storage barrel and a first mounting platform 120 supporting the liquid storage barrel. The bottom end of the body 110 is connected to the floor brush 200. The first mounting platform 120 is arranged on the body 110 and extends in a direction away from the body 110. The first mounting platform 120 has a first top 122 supporting the liquid storage barrel, a first bottom 123 opposite to the first top 122, and a first outer wall surface 124 connected between the first top 122 and the first bottom 123. The liquid storage barrel has a support portion 310, and the support portion 310 is surrounded to form a matching groove 311. When the liquid storage barrel is fixed on the first mounting platform 120, the first mounting platform 120 is embedded in the matching groove 311, and the first outer wall surface 124 is blocked by the support portion 310.

[0111] In this embodiment, the support portion 310 can shield the first mounting platform 120 to prevent the first mounting platform 120 from being exposed, that is, the first mounting platform 120 is hidden inside the sewage bucket 300, thereby improving the overall aesthetics of the cleaning device.

[0112] It should be pointed out that, regarding the specific structures of the main structure 100, the floor brush 200 and the liquid storage barrel, reference may be made to the contents described in the above-mentioned embodiment, and the present application will not repeat them here.

[0113] The following is a detailed description based on specific application scenarios, taking the cleaning equipment as a floor scrubber as an example.

[0114] Application scenario 1:

[0115] The user purchased a specially designed floor scrubber, in which a matching groove is formed at the bottom of a sewage bucket, and a first mounting platform is provided on the front of the machine body, which protrudes outward and is used to support the sewage bucket.

[0116] When the user installs the sewage bucket on the first mounting platform, he finds that the first mounting platform is embedded in the matching groove at the bottom of the bucket, which cleverly hides the first mounting platform itself. In addition, the joint edge between the sewage bucket and the mounting platform is cleverly placed under the platform. At the same time, the bottom of the sewage bucket is suspended in the air. From the front of the floor scrubber, the sewage bucket and the main structure form a visual effect of "sharing the same bottom surface". This design not only effectively avoids the exposure of the joint line and the first mounting platform, but also enhances the integrity and aesthetics of the appearance of the floor scrubber, presenting a more coordinated and consistent visual experience.

[0117] As users continue to clean, they gradually realize that the design of the bottom of the sewage bucket cleverly surrounds the side wall of the first mounting platform and extends downward from the top of the platform. This layout is not only more visually neat, but also significantly increases the capacity of the sewage bucket. This allows the floor scrubber to cover a larger cleaning area in a single operation, reducing the frequency of users dumping sewage during the cleaning process, thereby significantly improving cleaning efficiency and user experience.

[0118] Application scenario 2:

[0119] The user purchased a specially designed floor scrubber, in which two downwardly extending protrusions or protrusions are arranged at the bottom of the sewage bucket of the floor scrubber, and the bottom of the first mounting groove for accommodating the sewage bucket on the floor scrubber has an inclined surface inclined downward toward the opening direction of the first mounting groove, and two groove structures are arranged on the inclined surface. The groove structure has a special shape, specifically, the groove structure includes a limit section and a guide section that are interconnected, the guide section extends upward from the limit section, and the side of the limit section close to the opening of the first mounting groove is inclined toward the opening direction.

[0120] When the user installs the sewage bucket into the first installation groove, due to the large opening of the guide section, the user can easily insert the protrusion into the guide section, and then under the guidance of the groove structure, the sewage bucket can be rotated around the bottom inclined surface of the first installation groove into the first installation groove, and the limiting section cooperates with the protrusion to accurately assemble the sewage bucket into the first installation groove, so that the installation of the liquid storage bucket can be completed even without complete alignment, simplifying the alignment process, thereby reducing the user's cognitive burden and physical operation difficulty during the installation process, and improving the user experience.

[0121] At the same time, the sewage bucket is installed to the first mounting groove by rotating around the bottom inclined surface of the first mounting groove, so that the opening of the first mounting groove does not need to be made too large compared with the sewage bucket, and the liquid storage bucket can be easily installed in the first mounting groove, thereby effectively reducing the assembly gap between the sewage bucket and the first mounting groove, realizing small gap assembly, and improving the overall aesthetics of the floor scrubber.

[0122] Application scenario three:

[0123] The user purchased a cleverly designed floor scrubber, in which the cleaning liquid bucket and the sewage bucket are cleverly placed on the front of the machine, while the power source responsible for generating strong suction is set on the back of the machine and is set close to the floor brush.

[0124] When the user uses the handheld scrubber to clean the floor, the power source is close to the floor brush, which results in a lower center of gravity for the machine. The corresponding force required by the user's handheld end is reduced, making the user feel lighter when operating, and the grip is lighter. The scrubber can be easily controlled to perform cleaning work without exerting too much force. Secondly, because the cleaning liquid bucket and the sewage bucket are both located on the front of the machine, the user can easily see them while cleaning, so that the user can monitor the status of the two water tanks at any time, effectively reducing the anxiety caused by worrying about the sewage bucket being full or the cleaning liquid bucket being empty.

[0125] In short, the design of this floor scrubber takes the user experience into consideration, making cleaning easier, reducing psychological stress during operation, and improving cleaning efficiency.

[0126] It can be seen that the technical solution provided by the present application is that the first mounting platform is embedded in the matching groove of the liquid storage barrel to achieve docking and stable support between the liquid storage barrel and the first mounting platform. This design allows the liquid storage barrel to be conveniently installed on the first mounting platform according to the matching relationship between the matching groove and the first mounting platform, thereby simplifying the user's installation process and improving the accuracy and efficiency of the operation. At the same time, the upper edge of the first outer wall surface is not lower than the first bottom surface of the support portion, that is, the position where the support portion extends downward exceeds the upper edge of the first outer wall surface, so that the support portion can at least partially block the first outer wall surface, that is, the support portion can at least partially block the first mounting platform, and when the position where the support portion extends downward exceeds the lower edge of the first outer wall surface, the support portion can completely block the first outer wall surface of the first mounting platform, and the design scheme can also cleverly transfer the joining line between the first mounting platform and the liquid storage barrel from the side of the cleaning device to the bottom of the device, that is, a position that is out of sight in the normal use state, effectively hiding the joining line between the liquid storage barrel and the first mounting platform, visually forming a stealth effect of the first mounting platform, and further enhancing the appearance integrity and aesthetics of the cleaning device.

[0127] Furthermore, the upper edge of the first outer wall surface is not lower than the first bottom surface of the supporting portion, which means that the liquid storage barrel is partially located below the first top of the first mounting platform. When the liquid storage barrel is a hollow structure and is connected to the water outlet space in the liquid storage barrel, the corresponding water storage space of the liquid storage barrel can also extend downward from the top surface of the first mounting platform to expand the depth of the liquid storage barrel.

[0128] Furthermore, the top surface of the first mounting platform is provided with a first docking portion, the bottom end of the liquid storage barrel is provided with a second docking portion, and in the process of installing the liquid storage barrel to the main structure, the minimum matching gap between the second docking portion and the first docking portion changes from large to small. In other words, when the second docking portion is initially docked with the first docking portion, the matching gap between the second docking portion and the first docking portion is large, thereby allowing the user to insert the second docking portion into the first docking portion to complete the docking without complete alignment. When the second docking portion is further docked with the first docking portion, the matching gap between the second docking portion and the first docking portion is small, so that the liquid storage barrel can be accurately assembled to the main structure under the matching guidance of the second docking portion and the first docking portion. In this way, the installation of the liquid storage barrel can be completed even in the case of incomplete alignment, simplifying the alignment process, thereby reducing the user's cognitive burden and physical operation difficulty during the installation process, and improving the user experience.

[0129] Furthermore, the bottom of the liquid storage barrel rotates around the first top as the rotation center, and the top of the liquid storage barrel is assembled to the main structure by plane cooperation with the second mounting platform, so that the opening of the first mounting groove does not need to be made too large compared with the liquid storage barrel, and the liquid storage barrel can be easily installed in the first mounting groove. In addition, the assembly gap between the top of the liquid storage barrel and the side of the second mounting platform adjacent to the floor brush can be effectively reduced, thereby realizing small gap assembly and improving the overall aesthetics of the cleaning base station.

[0130] Furthermore, more than half of the power source is located between the second mounting platform and the floor brush, so that the center of gravity of the power source is arranged adjacent to the floor brush. In other words, when the cleaning device is in use, the center of gravity of the power source is arranged close to the bottom end of the cleaning device, thereby moving the overall center of gravity of the cleaning device downward, so that when the user holds the top of the cleaning device and pushes the cleaning device, the force of the cleaning device on the user's hand can be greatly reduced, that is, the user can use very little force to push the cleaning device to achieve the movement of the cleaning device, thereby improving the user's grip feel, facilitating the user's operation, and improving the user's experience.

[0131] Furthermore, the power source is inverted, and when the cleaning device is in use, the air inlet of the power source faces downward, which can reduce the possibility of dirt and / or water vapor condensing into water droplets falling directly into the motor under the influence of gravity, causing damage to the motor. At the same time, the air inlet of the power source and the air inlet of the sewage bucket are staggered, and the power source and the sewage bucket are designed in a front-to-back layout, so as to increase the length and number of bends of the air inlet duct, improve the water vapor separation effect, and further reduce the possibility of dirt and / or water vapor being absorbed into the power source.

[0132] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
