Description

Cleaning equipment Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] In the design of floor scrubbers, the connection between the wastewater tank and the main structure is based on a detachable structure to enable quick emptying and cleaning of the dirt inside the wastewater tank.

[0003] However, existing sewage tanks typically require aligning the inlet at the bottom of the tank with the fitting interface on the main structure before they can be accurately installed into the mounting slot. Furthermore, the mounting slot is generally a semi-enclosed design, with only the opening open for installation. The bottom of the slot, acting as an installation platform, usually has a downward-extending groove to allow the bottom of the sewage tank to be embedded and contained within it. Both the inlet at the bottom of the sewage tank and the fitting interface on the main structure are located out of sight during installation. This semi-enclosed design also limits the adjustment space during installation. Consequently, users must precisely align the bottom of the sewage tank with the corresponding groove and its limiting structure at the bottom of the mounting slot. Otherwise, multiple attempts and reliance on feel are necessary to accurately and correctly install the sewage tank onto the main structure, making the process cumbersome and significantly impacting the user experience.

[0004] At the same time, the limited space above and below the installation slot not only makes it inconvenient to install the wastewater tank, but also restricts the expansion of the wastewater tank's volume, or in other words, limits the liquid storage capacity of the wastewater tank, which is not conducive to improving the continuous operation capability of the floor scrubber. Summary of the Invention

[0005] The purpose of this application is to provide a cleaning device that simplifies the alignment process and facilitates the assembly of liquid storage tanks.

[0006] To achieve the above objectives, this application provides a cleaning device, which includes at least a main structure. The main structure includes a body, a liquid storage tank, and a first mounting platform supporting the liquid storage tank. The first mounting platform is disposed on the body and extends away from the body. The bottom of the liquid storage tank has a support portion, which forms a mating groove. The first mounting platform is embedded in the mating groove. The first mounting platform has a first top facing the liquid storage tank, a first bottom opposite to the first top, and a first outer wall surface connecting the first top and the first bottom. Along the length of the liquid storage tank, the upper edge of the first outer wall surface is not lower than the bottom surface of the support portion, and the bottom surface of the support portion forms at least a portion of the bottom surface of the main structure.

[0007] To achieve the above objectives, this application also provides a cleaning device, which includes at least a main structure, wherein the main structure has a liquid storage tank and a first mounting platform supporting the liquid storage tank; the bottom of the liquid storage tank has a support portion extending downward and suspended around the outside of the first mounting platform, and the bottom surface of the support portion forms at least a part of the bottom surface of the main structure.

[0008] To achieve the above objectives, this application also provides a cleaning device, which includes at least a main structure and a floor brush; the main structure includes a body, a liquid storage tank, and a first mounting platform supporting the liquid storage tank; the bottom end of the body is connected to the floor brush; the first mounting platform is disposed on the body and extends away from the body; the first mounting platform has a first top supporting the liquid storage tank, a first bottom opposite to the first top, and a first outer wall surface connecting the first top and the first bottom; the liquid storage tank has a support portion, which surrounds a mating groove; when the liquid storage tank is fixed on the first mounting platform, the first mounting platform is embedded in the mating groove, and the first outer wall surface is covered by the support portion.

[0009] Therefore, the technical solution provided in this application allows the first mounting platform to be embedded into the mating groove of the liquid storage tank, achieving docking and stable support between the liquid storage tank and the first mounting platform. This design allows the liquid storage tank to be conveniently installed on the first mounting platform based on the mating relationship between the mating groove and the first mounting platform, thereby simplifying the user's installation process and improving the accuracy and efficiency of operation. Simultaneously, the upper edge of the first outer wall is not lower than the bottom surface of the support portion; that is, the downward extension of the support portion at least exceeds the upper edge of the first outer wall, thus allowing the support portion to at least partially cover the first outer wall, i.e., to at least partially cover the first mounting platform. Furthermore, this design cleverly shifts the joint line between the first mounting platform and the liquid storage tank from the side of the cleaning equipment to the bottom of the equipment, i.e., a position out of sight under normal use, effectively hiding the joint line between the liquid storage tank and the first mounting platform, creating a visually concealed effect for the first mounting platform, further enhancing the overall appearance and aesthetics of the cleaning equipment.

[0010] Furthermore, the upper edge of the first outer wall is not lower than the bottom surface of the support, which means that the liquid storage tank is located below the first top of the first installation platform and suspended on the outer periphery of the first installation platform to form a support. When the support is a hollow structure and communicates with the water storage space inside the liquid storage tank, the water storage space of the corresponding liquid storage tank can also extend downward from the top surface of the first installation platform to increase the depth of the liquid storage tank. This ensures that the liquid position when the liquid storage tank is full is as far away from the top of the liquid storage tank as possible, thereby avoiding the probability of water vapor being sucked into the internal motor by the negative pressure airflow. At the same time, it increases the volume of the liquid storage tank and improves the continuous operation capability of the floor scrubber. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Terms used in this application to indicate spatial relative positions, such as “above,” “over,” “below,” “under,” “first end,” “second end,” “one end,” and “other end,” are used for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0031] Furthermore, the terms "installation," "setup," "equipped with," "connection," "sliding connection," "fixed," and "sleeve connection" should be interpreted broadly. 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, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] As people's living standards improve, more and more families are starting to use various cleaning equipment, such as floor scrubbers and robot vacuums, to reduce labor intensity and improve their quality of life. Taking floor scrubbers as an example, the machine provides clean water to the roller brush through a cleaning solution tank, helping the brush dissolve and clean stains on the floor. At the same time, the wastewater generated is pumped into a wastewater tank through a wastewater recycling pipe, forming a continuous cleaning cycle, thus efficiently completing the cleaning work.

[0033] In the design of the floor scrubber, the connection between the wastewater tank 300 and the main structure 100 is based on a detachable structure to enable rapid emptying and cleaning of the dirt inside the wastewater tank 300. As shown in Figure 18, the main structure 100 of the floor scrubber in the related technology has a liquid storage tank, including a cleaning liquid tank 400 located above and a wastewater tank 300 located below. The main structure 100 is provided with mounting grooves for accommodating the wastewater tank 300 and the cleaning liquid tank 400, respectively. Both mounting grooves are recessed laterally inward from the outer side of the main structure 100. The wastewater tank 300 and the cleaning liquid tank 400 are respectively embedded into the main structure 100 through their corresponding mounting grooves, so that the mounting grooves form a semi-enclosed connection between the wastewater tank 300 and the cleaning liquid tank 400.

[0034] In practical use, taking the sewage tank 300 as an example, when installing the sewage tank 300, the sewage inlet at the bottom of the sewage tank 300 needs to be aligned with the interface at the bottom of the installation groove before it can be accurately installed into the installation groove. The bottom of the installation groove is the installation platform. The sidewalls, top surface, and bottom surface of the sewage tank installation groove surround part of the outer surface of the sewage tank 300. The sidewalls of the sewage tank installation groove extend upward around the bottom surface to form a recessed groove structure. The bottom of the sewage tank is embedded in the groove structure. The top surface of the sidewall located at the bottom of the installation groove and extending around the body is higher than the bottom surface of the sewage tank. This part of the sidewall that is higher than the bottom surface of the installation groove can prevent sewage dripping from the sewage tank from flowing out of the groove structure, but it also means that the bottom of the sewage tank needs to pass over the obstruction of the sidewall before entering the groove structure when installing. The aforementioned groove structure is set on the installation platform. When the sewage tank 300 is initially placed into the mounting groove, it needs to tilt to overcome the obstruction of the side wall of the groove structure and enter the groove structure of the mounting platform. The bottom of the sewage tank extends into the groove structure of the mounting platform before the rest of the tank and contacts its bottom surface. Because the sewage tank 300 is tilted into the groove structure, a part of the bottom of the sewage tank first makes partial contact with the bottom surface of the mounting platform, achieving point support. Then, it rotates using this support point, so that the entire bottom of the sewage tank is completely embedded in the groove structure of the mounting platform. To ensure that the sewage tank 300 is installed in the correct position and that the inlet and outlet are not fully aligned due to rotation or tilting, resulting in sewage leakage into the groove space, the groove space of the mounting platform is generally equipped with protrusions or further recessed grooves to limit the rotation of the bottom of the sewage tank 300. The fit gap between the bottom of the sewage tank 300 and the mutually cooperating limiting structure in the groove of the mounting platform is very small, thus preventing the sewage tank from being installed out of position and achieving precise installation. Because the sewage tank 300 is embedded within the main structure 100, the side walls, top surface, and bottom surface of the mounting groove partially surround the outer surface of the sewage tank 300. This obstructs the positions of the inlet and the connecting interface, as well as the limiting structures that require precise alignment. In other words, the inlet at the bottom of the sewage tank 300, the connecting interface on the main structure 100, and the limiting structures requiring precise alignment are all located in positions invisible to the user during installation. Furthermore, since the sewage tank 300 is embedded within the main structure 100, the top and bottom surfaces of the mounting groove also surround the sewage tank 300, limiting the vertical adjustment space of the sewage tank 300 during installation. This forces users to repeatedly adjust the sewage tank's vertical and horizontal positions within the mounting groove, relying on feel to accurately and correctly install the sewage tank 300 onto the main structure 100, avoiding reduced suction and sewage leakage due to inaccurate alignment of the inlet and connecting interface. This cumbersome operation significantly impacts the user experience.

[0035] Meanwhile, the aforementioned wastewater tank 300 is embedded within the main structure 100, and the upper and lower walls of the mounting groove surround the wastewater tank 300. Clearly, this design prevents the top or bottom of the wastewater tank 300 from extending outwards along its length into the mounting groove, thus limiting the volume expansion of the wastewater tank 300 and consequently restricting its liquid storage depth, which is detrimental to improving the continuous operating capability of the floor scrubber. Furthermore, when the wastewater tank 300 is installed in the mounting groove, the junction line between the bottom of the wastewater tank 300 and the lower wall of the mounting groove is located on the side of the entire structure, affecting the overall aesthetics of the floor scrubber.

[0036] Therefore, this application redesigns the mating structure between the bottom of the storage tank, especially the sewage tank 300, and the mounting platform. This simplifies the alignment process, facilitates tank assembly, expands the storage tank's capacity, and improves the overall aesthetics of the cleaning equipment. Specifically, a groove shape adapted to the mounting platform is formed at the bottom of the sewage tank 300. During assembly, the mounting platform on the main structure 100 is embedded into this groove. Thus, the sewage tank 300 can be conveniently installed on the first mounting platform based on the mating relationship between the groove and the mounting platform, thereby simplifying the user's installation process and improving operational accuracy and efficiency. Furthermore, after assembly, the bottom of the wastewater tank 300 is suspended around the periphery of the mounting platform, unrestricted by the mounting groove space formed by the mounting platform and the main body 110 of the machine. This allows the bottom of the wastewater tank 300 to extend downwards along its length, increasing its depth and ensuring that the liquid level when the tank is full is as far away from the top as possible. This reduces the probability of water vapor being drawn into the internal motor by the negative pressure airflow, while also increasing the tank's capacity and improving the floor scrubber's continuous operating capability. This structural design also allows for the concealment of the mounting platform and the relocation of the junction between the wastewater tank 300 and the mounting platform to a lower, invisible area during normal use, thus improving aesthetics.

[0037] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0038] The cleaning equipment provided in this application can be a cleaning robot with cleaning functions such as washing, sweeping, and mopping. The cleaning equipment can automatically move on the surface to be cleaned to perform cleaning work. Of course, the cleaning equipment can also be a handheld floor scrubber with cleaning functions such as washing, sweeping, and mopping. The user holds the cleaning equipment and pushes it on the surface to be cleaned to perform cleaning work. There is no limitation on this.

[0039] Referring to Figures 1 to 3, in one feasible embodiment, the cleaning equipment may include at least a main structure 100. The main structure 100 includes a body 110, a liquid storage tank, and a first mounting platform 120. The body 110, as the main part of the cleaning equipment, primarily serves to support and protect other components on the cleaning equipment. The first mounting platform 120 is disposed on the body 110 and extends away from the body 110 to form a suspension. In this embodiment, the first mounting platform 120 may extend from the body 110 along a main extension line 111 perpendicular to the body 110 and away from the body 110, and be suspended in mid-air. It should be noted that the body 110 has a top end and a bottom end arranged opposite each other along its length, and the main extension line 111 refers to the straight line connecting the top end and the bottom end of the body 110.

[0040] In one feasible implementation, the body 110 is connected to the floor brush 200 via a pivot, and the top of the body 110 is provided with a handle for easy gripping by the user, who uses the handle to move the main structure 100 and the floor brush 200.

[0041] In practical applications, the main structure 100 can pivot relative to the brush 200 at a certain angle, making it easier for the cleaning device to clean under furniture or in narrow spaces. In other words, the main structure 100 can tilt or even lie flat to accommodate cleaning needs at different heights. Furthermore, it caters to users of different heights, allowing for greater flexibility and convenience when using the floor scrubber. Users can operate it easily without bending or squatting, and this design also helps reduce the physical burden on users during the cleaning process.

[0042] The first mounting platform 120 is used to mate with the bottom of the liquid storage tank to connect with and support the tank. Specifically, the first mounting platform 120 has a first top 122, a first bottom 123, and a first outer wall surface 124 facing the liquid storage tank. The first bottom 123 is disposed opposite to the first top 122, and the first outer wall surface 124 connects the first top 122 and the first bottom 123. The first bottom 123 is suspended and faces the floor brush. In other words, the first mounting platform 120, except for the part connected to the main structure 100, is suspended above the floor brush. The bottom of the liquid storage tank has a support portion 310. The support portion 310 forms a mating groove 311 on a plane intersecting the length direction of the liquid storage tank, and the support portion 310 has a notch 312 facing the outer wall of the liquid storage tank. For ease of description, the bottom surface of the support portion 310 is defined as the first bottom surface 313. When the liquid storage tank is installed on the main structure 100, the first mounting platform 120 can be inserted into the mating groove 311 through the notch 312. Along the length of the liquid storage tank, the upper edge 1242 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 mounting 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 mounting platform 120. Note that the support portion 310 surrounding the outer side surface of the first mounting platform 120 can be a continuously extending U-shaped structure, or the support portion 310 can have a discontinuous area forming a shape that surrounds the first mounting platform 120.

[0043] In another feasible embodiment, the support portion at the bottom of the liquid storage tank forms a mating groove on a plane intersecting the length direction of the liquid storage tank, but without any notch. Referring to the mutually perpendicular X and Y axes in Figure 6, the portion of the support portion adjacent to the main structure 100 and extending along the directions perpendicular to both the X and Y axes in Figure 6 is embedded into the corresponding groove on the top of the first mounting platform, thereby achieving a limiting effect on the liquid storage tank. This support portion can be a hollow structure communicating with the internal space of the liquid storage tank, or it can be a solid structure.

[0044] In practical applications, the liquid storage tank can be used as either a wastewater tank 300 or a cleaning liquid tank 400. When used as a cleaning liquid tank 400, the tank supplies liquid to the floor brush 200 for cleaning purposes. The bottom surface of the first mounting platform 120 faces the floor brush. When used as a wastewater tank 300, it collects and holds the dirt generated during the cleaning process.

[0045] It is worth mentioning that this application achieves docking and stable support between the liquid storage tank and the first mounting platform 120 by embedding the first mounting platform 120 into the mating groove 311 at the bottom of the liquid storage tank. This design allows the liquid storage tank to be conveniently installed on the first mounting platform 120 according to the mating relationship between the mating groove 311 and the first mounting platform 120, thereby simplifying the user's installation process and improving the accuracy and efficiency of operation. Meanwhile, the upper edge 1242 of the first outer wall surface 124 is not lower than the first bottom surface 313, and the support part 310 at least partially covers the first outer wall surface 124 of the first mounting platform 120. When the lower edge 1241 of the first outer wall surface 124 is not lower than the first bottom surface 313 of the support part 310, that is, when the position of the support part 310 extending downward exceeds the lower edge 1241 of the first outer wall surface 124, the support part 310 can cover the first outer wall surface 124, that is, the support part 310 can cover the first mounting platform 120. In addition, this design can also cleverly transfer the joint line between the first mounting platform 120 and the liquid storage tank from the side of the cleaning equipment to the bottom of the equipment, that is, a position that is not visible under normal use, effectively hiding the joint line between the liquid storage tank and the first mounting platform 120, creating a visually invisible effect for the first mounting platform, and further enhancing the overall appearance and aesthetics of the cleaning equipment.

[0046] Furthermore, it is understood that the liquid storage tank is located below the first top 122 of the first mounting platform 120, and the corresponding water storage space of the liquid storage tank can also extend downward from the top surface of the first mounting platform 120 to increase the depth of the liquid storage tank. Specifically, as shown in Figure 4, in one feasible embodiment, the support 310 can be made into a hollow structure, and the internal space of the support 310 can serve as part of the liquid storage space inside the liquid storage tank to accommodate fluid substances (such as dirt or liquid). In other words, the liquid storage space inside the liquid storage tank can extend downward using the support 310 portion, so that the liquid position when the solution tank is full is as far away from the top of the solution tank as possible, thereby avoiding the probability of water vapor being sucked into the internal motor by the negative pressure airflow, and also increasing the ability to operate continuously.

[0047] In another alternative embodiment, the support portion 310 can 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 tank.

[0048] In practical applications, the support part 310 can be an extension of the liquid storage tank itself, and the support part 310 can be integrally designed with the liquid storage tank. Of course, the support part 310 can also be designed separately from the liquid storage tank itself, and then connected to the bottom of the liquid storage tank itself by welding, bonding or hot melting, etc. This application does not make specific limitations on this.

[0049] In one feasible implementation, the support portion 310 can extend along the periphery of the liquid storage tank, and the outer wall of the support portion 310 is part of the outer wall of the liquid storage tank and smoothly connected thereto. That is, the outer surface of the support portion 310 is integrated with the outer surface of the liquid storage tank and has a smooth transition, thus enhancing the visual appeal of the product 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 tank, that is, the outer wall of the support portion 310 may be recessed inward or extended outward from the outer wall of the liquid storage tank.

[0051] Since the storage tank needs to be detached from the main structure 100 for use, whether it is used as a sewage tank or a cleaning fluid tank, in order to prevent the storage tank from tipping over when placed independently on the ground, in one feasible embodiment, the bottom surface of the support part 310 is perpendicular to the length direction of the storage tank. In other words, the bottom surface of the support part 310 is a plane, and the bottom surface of the storage tank forms a 90-degree angle with the length direction of the storage tank. This allows the storage tank to stand stably on a horizontal surface (such as the ground or the surface of an object) through the bottom surface of the support part 310, thereby preventing the storage tank from tipping over.

[0052] Referring to Figures 3 and 8, in one feasible embodiment, the support portion 310 extends downward from the bottom of the liquid storage tank 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 one feasible implementation, the support portion 310 is suspended around the outer periphery of the first mounting platform 120. That is, the first bottom surface 313 of the support portion 310 is suspended and does not contact other surfaces; specifically, the support portion 310 is suspended around the first outer wall surface 124 of the first mounting platform 120, so that the first bottom surface 313 of the support portion 310 can visually form the bottom surface of the main structure 100. Specifically, the first bottom 123 of the first mounting platform 120 and the first bottom surface 313 of the support portion 310 together form the bottom surface of the main structure, and the first bottom surface 313 of the support portion is located on the outer side of the bottom of the first mounting platform 120. The suspended portion can be a hollow structure to communicate with the liquid storage space of the liquid storage tank to expand the liquid storage capacity.

[0054] In another alternative embodiment, the support portion 310 may also protrude downwards from the bottom of the storage tank to form other shapes, such as C-shape, V-shape, etc. Referring also to Figures 4 to 7, in one feasible embodiment, a first docking portion 121 is formed on the first mounting platform 120, and correspondingly, a second docking portion 3111 is formed on the bottom and / or wall of the mating groove 311 to dock with the first docking portion 121. During the process of installing the storage tank to the main structure 100, the mating gap between the second docking portion 3111 and the first docking portion 121 decreases. In other words, during the initial docking of the second docking part 3111 and the first docking part 121, as shown in Figures 4 and 5, the mating gap between the second docking part 3111 and the first docking part 121 is relatively large. This allows the user to insert the second docking part 3111 into the first docking part 121 to complete the initial docking even if the parts are not fully aligned. Building upon this, during further docking of the second docking part 3111 and the first docking part 121, as shown in Figures 6 and 7, the mating gap between the second docking part 3111 and the first docking part 121 is smaller. This allows the liquid storage tank to be precisely assembled onto the first mounting platform 120 under the guidance of the mating of the second docking part 3111 and the first docking part 121. In this way, the installation of the liquid storage tank can be completed even if the parts are not fully aligned, achieving blind insertion installation, simplifying the alignment process, reducing the user's attention and physical operational difficulty during installation, and improving the user experience.

[0055] Regarding the specific structure of the first docking part 121 and the second docking part 3111 described above, this application provides three possible embodiments for reference.

[0056] Example 1: As shown in Figures 4 and 5, the first docking portion 121 can be constructed as a tank structure, and the second docking portion 3111 can be constructed as a protrusion structure. Specifically, the tank 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 during the process of installing the liquid storage tank into the main structure 100, the second docking portion 3111 passes through the guiding section 1212 and the limiting section 1211 in sequence.

[0057] Example 2: The first docking portion 121 can be constructed as a protruding structure, and the second docking portion 3111 can be constructed as a tank structure. Specifically, the tank 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 during the process of installing the liquid storage tank into the main structure 100, the second docking portion 3111 passes through the guiding section 1212 and the limiting section 1211 in sequence.

[0058] Example 3: One of the first docking part 121 and the second docking part 3111 is an arc-shaped claw or an arc-shaped groove, and the other is a horizontally extending protrusion. During the installation of the storage tank on the main structure 100, the protrusion can easily enter the arc-shaped claw or arc-shaped groove through the arc-shaped claw or arc-shaped groove, and abut against the inner bottom surface of the arc-shaped claw or arc-shaped groove. The rotating installation of the sewage tank is realized by using the mating abutment part as the rotation axis, thereby allowing the installation of the storage tank to be completed quickly even if it is not completely aligned.

[0059] Taking the first docking portion 121 in Embodiment 1 as a tank structure and the second docking portion 3111 as a protruding structure, and the first docking portion 121 having a mutually communicating limiting section 1211 and guiding section 1212 as an example. In one feasible embodiment, the protruding structure extends along the length direction of the liquid storage tank 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 body 110 is defined as the guiding surface 12121, the side of the limiting section 1211 connected to the guiding surface 12121 is the abutting surface 12111, and the guiding surface 12121 and the abutting surface 12111 are connected by a transition surface 12122. The guide surface 12121 extends outwards while moving towards the top of the body 110, thus increasing the opening range of the guide section 1212. This ensures that the gap formed by the guide section 1212 is at least partially larger than the gap formed by the limiting section 1211, allowing the user to insert the second mating part 3111 into the first mating part 121 even without complete alignment, facilitating assembly. The guide surface 12121 can be an inclined surface extending straight at a certain angle, or an inclined surface with an arc-shaped curve. The abutment surface 12111 is a straight surface parallel to the length extension direction of the protruding structure, so that after the liquid storage tank is installed in place, it fits against the protruding structure away from the abutment surface 12111, thus achieving limiting.

[0060] In practical applications, as shown in Figure 5, the gap formed by the guide section 1212 can be increased simply by extending the guide surface 12121 outward while extending towards the top of the fuselage 110. Alternatively, the guide section 1212 can have two opposing guide surfaces 12121, and both guide surfaces 12121 can extend outward while extending towards the top of the fuselage 110, thereby increasing the gap formed by the guide section 1212. This application does not specifically limit this approach.

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

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

[0063] Each of the aforementioned first docking part 121 and second docking part 3111 may have one. Of course, each of the first docking part 121 and second docking part 3111 may also have two.

[0064] As shown in Figure 8, in one feasible embodiment, there are two first docking portions 121 and two second docking portions 3111. The two first docking portions 121 are 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 portion 121 communicates with both the top surface and the side wall of the first mounting platform 120. The two second docking portions 3111 are located on opposite sides of the groove wall of the mating groove 311. Furthermore, the two first docking portions 121 and the two second docking portions 3111 correspond one-to-one. Thus, when the liquid storage tank is installed onto the first mounting platform 120, the two second docking portions 3111 are inserted into the two first docking portions 121, thereby distributing the force, reducing stress wear and breakage, and improving service life.

[0065] Referring to Figures 2 and 7, in one feasible embodiment, the first top 122 is constructed as an inclined surface structure tilted downwards from the fuselage 110. This first top 122 can be a straight inclined surface, a curved inclined surface, or a straight inclined surface with partial stepped protrusions. The bottom of the mating groove 311 matches the top surface of the first mounting platform 120; that is, the bottom of the mating groove 311 is also constructed as an inclined surface, and the slope of the bottom of the mating groove 311 is approximately the same as the slope of the top surface of the first mounting platform 120. Thus, when the liquid storage tank is installed onto the first mounting platform 120, the first mounting platform 120 passes through the notch 312 and embeds itself into the mating groove 311, allowing the bottom of the mating groove 311 to contact and support the liquid storage tank. Meanwhile, the inclined surface structure of the first top 122 also facilitates the rotation and installation of the liquid storage tank by using the contact surface of the two as a rotation support point during the process of the tank bottom and the first top 122 fitting together.

[0066] Furthermore, it is understandable that, since the first top 122 is inclined downward from the body 110, when the liquid storage tank is installed on the first top 122, under the action of its own weight, the liquid storage tank tends to slide downward along the first top 122, thereby causing the second docking part 3111 to slide downward along the inclined direction of the first top 122 and cooperate with the abutment surface 12111, so as to reduce the possibility of the liquid storage tank wobbling relative to the main body structure 100 due to the mating gap between the second docking part 3111 and the limiting section 1211, thereby improving the assembly stability of the liquid storage tank on the main body structure 100.

[0067] To further improve the installation stability of the liquid storage tank, please refer to Figures 5 and 7. In one feasible embodiment, the inner wall of the support portion 310 matches the first outer wall surface 124; that is, the shape and size of the inner wall of the support portion 310 match the first outer wall surface 124. Thus, when the first mounting platform 120 passes through the notch 312 and is inserted into the mating groove 311, the inner wall of the support portion 310 mates with the first outer wall surface 124. In this way, the combined action of the second mating portion 3111 abutting with the abutting surface 12111 and the inner wall of the support portion 310 mates with the first outer wall surface 124, more securely fixing the lower part of the liquid storage tank to the first mounting platform 120.

[0068] In this embodiment, when the liquid storage tank needs to be installed on the first mounting platform 120, the user can first tilt and insert the second docking part 3111 of the liquid storage tank into the guide section 1212. Then, the liquid storage tank is rotated about the first mounting platform 120 as the axis of rotation towards the machine body 110. During the rotation, one side of the second docking part 3111 rotates and moves along the bend between the guide section 1212 and the limiting section 1211 (i.e., the transition surface 12122) and gradually inserts into the limiting section 1211. During the rotation, the second docking part 3111 maintains contact with the transition surface 12122 between the guide surface 12121 and the abutment surface 12111 until the second docking part 3111 and the abutment surface 12111 are in contact. The liquid storage tank moves to the top of the first mounting platform 120, and the upper part of the liquid storage tank is detachably connected to the machine body 110, thereby completely constraining the six degrees of freedom of the liquid storage tank and completing the installation operation.

[0069] Referring again to Figure 2, in one feasible 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 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 together form a first mounting groove 140 for accommodating the liquid storage tank. In this embodiment, the top surface of the liquid storage tank and the bottom surface of the second mounting platform 130 are both constructed as planar structures. When the liquid storage tank is installed in the first mounting groove 140, the top surface of the liquid storage tank is parallel to and opposite to the bottom surface of the second mounting platform 130, and the top surface of the liquid storage tank is a closed surface. In practical applications, the top surface of the liquid storage tank may be provided with protrusions, which can support the second mounting platform 130 when the liquid storage tank is installed in the first mounting groove 140.

[0070] It is worth mentioning that this application utilizes the top surface of the liquid storage tank as the rotation center, and the top surface of the liquid storage tank is assembled onto the main structure 100 with the second mounting platform 130 through a planar fit. This allows the opening of the first mounting groove 140 to be less than that of the liquid storage tank, facilitating the installation of the liquid storage tank into the first mounting groove 140. This effectively reduces the assembly gap between the top surface of the liquid storage tank and the bottom surface of the second mounting platform 130, achieving small-gap assembly and improving the overall aesthetics of the cleaning base station. The distance between the top and bottom surfaces of the first mounting groove 130 is less than the distance between the top and bottom surfaces of the liquid storage tank; 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 less than the distance between the top and bottom surfaces of the liquid storage tank.

[0071] Along the length of the storage tank, the bottom surface of the storage tank, or the bottom surface of the support 310, is lower than the bottom surface of the first mounting groove 130, ensuring that the height of the storage tank is not limited by the height inside the first mounting groove 130, thus preventing the expansion of the storage capacity.

[0072] Along the length of the storage tank, the projected area of ​​the support portion 310 is larger than the projected area of ​​the first mounting platform 120, and the projected area of ​​the second mounting platform 130 is larger than the projected area of ​​the first mounting platform 120. The projected area of ​​the first mounting platform 120 is a part of the projected area of ​​the support portion 310, and the projected area of ​​the first mounting platform 120 is a part of the projected area of ​​the second mounting platform 130.

[0073] The gap between the top surface of the liquid storage tank and the bottom surface of the second mounting platform 130 shall not exceed 2 mm. Preferably, the gap between the top surface of the liquid storage tank and the bottom surface of the second mounting platform 130 shall not exceed 1 mm.

[0074] The aforementioned storage tank can be used as a wastewater tank 300 or a cleaning fluid tank 400. However, considering that the wastewater tank 300 should be located near the bottom of the machine body 110, the dirt adsorbed from the floor brush 200 can be efficiently sucked into the wastewater tank 300. Therefore, the aforementioned storage tank is preferably used as a wastewater tank 300.

[0075] In practical applications, when the storage tank is used as a sewage tank 300, an inlet should be provided on the bottom of the groove 311, and a connector should be provided on the top surface of the first mounting platform 120. When the sewage tank 300 is installed in the first mounting groove 140, the inlet and the connector are sealed and connected by a flexible rubber part 160. The flexible rubber part 160 surrounds the connector and protrudes from the first mounting platform 120. A recessed area (as shown in Figure 8) is provided around the inlet of the groove 311 to fit the flexible rubber part 160, so as to make an interference contact with the flexible rubber part 160 protruding from the top surface of the first mounting platform. At the same time, the flexible rubber part 160 can also serve as part of the support for the storage tank in the recessed area. In this way, the dirt sucked up from the floor brush 200 can flow into the sewage tank 300 for storage through the connector and the inlet.

[0076] Referring again to Figure 1, in one feasible embodiment, the cleaning equipment may further include a cleaning liquid tank 400, which is used to hold liquid (clean water or cleaning solution). The liquid in the cleaning liquid tank 400 flows towards the floor brush 200 to dissolve stains and improve the cleaning effect. The cleaning liquid tank 400 is connected to the main body 110 and is located above the wastewater tank 300, so that the liquid in the cleaning liquid tank 400 can flow out smoothly under gravity.

[0077] Furthermore, the main body 110 has a front 112 and a back 113 facing away from each other, with the front 112 located on the side of the main body 110 adjacent to the floor brush 200, and the wastewater tank 300 and cleaning solution tank 400 located on the front 112. In this way, when the user is using the cleaning equipment to clean the surface, the main body 110 is tilted, with the front 112 above the main body 110 and the back 113 below the main body 110. Positioning the wastewater tank 300 and cleaning solution tank 400 on the front 112 makes it easier for the user to observe the levels in both tanks, improving the user experience. Furthermore, compared to related technologies where the wastewater tank 300 and cleaning fluid tank 400 are located below the body 110, in this application, the wastewater tank 300 and cleaning fluid tank 400 are located above the body 110. The body 110 can provide support for the wastewater tank 300 and cleaning fluid tank 400, reducing the stress at the connection between the wastewater tank 300 and cleaning fluid tank 400 and the body 110, reducing the possibility of damage, and increasing service life. After the wastewater tank 300 is installed in place, viewed from the front 112 direction, the first bottom surface 313 of the wastewater tank 300 is suspended above the body 110, and the wastewater tank 300 covers the first mounting platform 120, preventing the first mounting platform 120 from being exposed. That is, the first mounting platform 120 is hidden inside the wastewater tank 300. At the same time, the first bottom surface 313 of the wastewater tank 300 is set close to the bottom end of the main structure 100, so that the first bottom surface 313 of the wastewater tank 300 can form a visual effect similar to the bottom surface of the main structure 100.

[0078] In practical applications, the second mounting platform 130 cooperates with the body 110 to form a second mounting groove 150, which is used to accommodate the cleaning fluid tank 400. The top surface of the second mounting platform 130 may be provided with a water inlet. When the cleaning fluid tank 400 is installed in the second mounting groove 150, the cleaning fluid tank 400 is sealed and connected to the water inlet, so that the liquid in the cleaning fluid tank 400 can flow to the floor brush 200 through the water inlet.

[0079] Referring to Figures 2 and 9, in one feasible embodiment, the cleaning fluid tank 400 is slidably connected to the body 110 via a dovetail groove structure, and a snap-fit ​​structure is provided between the cleaning fluid tank 400 and the body 110. In practical applications, when the cleaning fluid tank 400 needs to be installed in the second mounting slot 150, the user can first slide the cleaning fluid tank 400 from top to bottom through the corresponding dovetail groove structure until the cleaning fluid tank 400 is sealed and connected to the water supply port, and the snap-fit ​​structure between the cleaning fluid tank 400 and the body 110 engages with each other, thereby completing the installation and fixing of the cleaning fluid tank 400.

[0080] As shown in Figures 9 and 10, in one feasible embodiment, the cleaning fluid container 400 may include a first container body 410 and a first container lid 420. The first container lid 420 is detachably connected to the first container body 410. When the first container lid 420 is connected to the first container body 410, the first container lid 420 seals the opening of the first container body 410 to prevent liquid from leaking out of the first container body 410. When the first container lid 420 and the first container body 410 are separated, the user can add water to the first container body 410 through the opening.

[0081] In this embodiment, a drain valve 430 can be integrated into the first lid 420. The cleaning fluid tank 400 is installed upside down on the second mounting platform 130. When the cleaning fluid tank 400 is installed upside down on the second mounting platform 130, the drain valve 430 can be opened at the water supply port on the second mounting platform 130, allowing the liquid in the cleaning fluid tank 400 to flow through the drain valve 430 and through the water supply port on the second mounting platform 130 to the floor brush 200. Furthermore, compared to integrating the drain valve 430 into the first tank body 410, integrating the drain valve 430 into the first lid 420 reduces the processing difficulty of the cleaning fluid tank 400. At the same time, when water is poured into the first tank body 410, it can prevent the liquid in the first tank body 410 from accidentally flowing out through the drain valve 430, improving the user experience.

[0082] Furthermore, a one-way sealing structure 440 can be connected to the first tank body 410 or the first tank lid 420. The one-way sealing structure 440 is used to connect the air inside the cleaning fluid tank 400 with the external environment to balance the pressure difference between the inside and outside, while preventing the liquid inside the cleaning fluid tank 400 from flowing to the outside through the one-way sealing structure 440. In practical applications, the specific structure of the one-way sealing structure 440 can refer to the duckbill valve structure, which will not be described in detail here.

[0083] Preferably, the one-way sealing structure 440 should be disposed on the first tank body 410, and the one-way sealing structure 440 is located at the end of the first tank body 410 away from the first tank cover 420. In this way, when the cleaning liquid tank 400 is installed upside down on the second mounting platform 130, the one-way sealing structure 440 is located above the cleaning liquid tank 400. As the liquid in the cleaning liquid tank 400 gradually flows out, the liquid in the cleaning liquid tank 400 is mostly located below the one-way sealing structure 440, which can reduce the continuous pressure of the liquid in the cleaning liquid tank 400 on the one-way sealing structure 440 and improve the service life of the one-way sealing structure 440.

[0084] Since users need to hold the top of the cleaning equipment to move it during use, to reduce the force required on the equipment, as shown again in Figures 1 and 2, in one feasible embodiment, the cleaning equipment also includes a power source 500. The power source 500 is used to draw air from the wastewater tank 300 to create a negative pressure within it, thereby drawing dirt from the floor brush 200 into the wastewater tank 300 under the combined internal and external pressure. The power source 500 is located behind the storage tank, mounted on the back 113 of the main body 110, behind both the wastewater tank 300 and the cleaning fluid tank 400, and is positioned close to the floor brush 200, with more than half of its portion located between the second mounting platform 130 and the floor brush 200, thus positioning the center of gravity of the power source 500 near the floor brush 200. In other words, when the cleaning equipment is in use, the center of gravity of the power source 500 is set close to the bottom of the cleaning equipment, thereby lowering the overall center of gravity of the cleaning equipment. In this way, when the user holds the top of the cleaning equipment and pushes it, the force exerted on the user's hand by the cleaning equipment can be greatly reduced. That is to say, the user can use very little force to push the cleaning equipment to move it, improving the user's grip, making it more convenient to use and operate, and enhancing the user experience.

[0085] In practical applications, the power source 500 can consist of a motor and an impeller. The motor drives the impeller to rotate at high speed. When the impeller rotates at high speed, it can draw in air and expel it outward, thus creating negative pressure. The power source 500 can be installed as a separate component into the cleaning equipment, or it can be removed from the cleaning equipment as a whole, facilitating subsequent maintenance and replacement. In another optional embodiment, the power source 500 can also be integrated into the cleaning equipment as a non-removable or difficult-to-remove part of the equipment.

[0086] To reduce the likelihood of dirt and / or moisture in the wastewater tank 300 being drawn into the power source 500, and to extend the service life of the power source 500, please refer to Figures 11 and 12. In one feasible embodiment, the air inlet of the power source 500 can be positioned towards the bottom of the body 110. That is, the power source 500 is inverted. Thus, when the cleaning equipment is in use, the air inlet of the power source 500 faces downwards. Under the influence of gravity, this reduces the likelihood of water droplets condensed from dirt and / or moisture falling directly into the motor and causing damage.

[0087] In this embodiment, when the sewage tank 300 is installed in the first mounting slot 140, the air inlet of the power source 500 is connected to the negative pressure port of the sewage tank 300 through the air inlet duct 600. 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 tank 300, and is partially disposed within the body 110. The air inlet 510 of the power source 500 is located below the negative pressure port 370 of the sewage tank 300, achieving a staggered arrangement. Simultaneously, in conjunction with the aforementioned front-to-back layout design of the power source 500 and the sewage tank 300, the length and number of bends of the air inlet duct 600 are maximized to improve the water vapor separation effect and further reduce the possibility of dirt and / or water vapor being drawn into the power source 500.

[0088] In one alternative implementation, 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 tank 300 using a pipe design such as a flexible hose or a rigid pipe.

[0089] In another alternative embodiment, the air inlet duct 600 may also be a channel formed entirely by the inner wall of the body 110, and the air inlet duct 600 may be formed during the molding process of the body 110.

[0090] In another alternative embodiment, the air inlet duct 600 may be partially formed by a channel surrounded by the inner wall of the housing 110, and partially formed by a duct design or surrounded by the outer shell structure of the power source 500. Specifically, referring to Figures 5 to 11, the air inlet duct 600 may include a first air duct 610 and a second air duct 620. The first air duct 610 is formed inside the housing 110, and a first air vent 611 for communicating with the negative pressure port 370 of the sewage tank 300 is formed on the front side 112 located in the first mounting groove 140, and a second air vent 612 is formed on the back side 113. The second air duct 620 is constructed in an L-shape. The second air inlet 612 is connected to the air inlet 510 of the power source 500 through the second air duct 620. The L-shaped second air duct 620 includes a horizontal section and a vertical section. The air inlet 510 of the power source 500 is connected to the top of the vertical section, ensuring that water droplets condensing in the air duct gather at the bottom of the horizontal section due to gravity and cannot be damaged by negative pressure suction passing through the vertical section into the power source. When the power source 500 is running, the power source 500 sequentially draws air from the sewage tank 300 through the second air duct 620, the first air duct 610, and the negative pressure port 370 of the sewage tank 300 to create negative pressure inside the sewage tank 300. At the same time, by increasing the total length of the air duct, water vapor separation is achieved, reducing the risk of water vapor directly entering the power source 500.

[0091] For the specific structure of the sewage tank 300, please refer to Figures 13 and 14. The sewage tank 300 includes a second tank body 320 and a second tank cover 330. The second tank cover 330 is detachably connected to the second tank body 320 and covers the opening of the second tank body 320. A third air duct 630 is formed inside the second tank cover 330. The third air duct 630 extends upward from the opening of the second tank body 320 along the length direction of the sewage tank 300 and then extends in a direction approximately perpendicular to the length direction of the sewage tank 300, thereby forming a negative pressure port 370 of the sewage tank 300 on the side of the second tank cover 330. When the sewage tank 300 is installed in the first mounting groove 140, the negative pressure port 370 is connected to the first air vent 611, so that the air in the second tank body 320 flows sequentially through the third air duct 630, the first air duct 610, and the second air duct 620 to the power source 500. This increases the number of bends in the duct from the inside of the sewage tank 300 to the air inlet of the power source 500, thereby further improving the water vapor separation effect and reducing the possibility of water vapor entering the power source 500.

[0092] In one feasible implementation, a filter element 340 is detachably connected to the second bucket lid 330. The plane of the filter element 340 is approximately parallel to the length direction of the sewage bucket 300, and the filter element 340 is located at the negative pressure port 370. Specifically, it is located inside the negative pressure port 370 and adjacent to the first air duct 611, thereby filtering 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 tank 300, allowing for replacement of the filter element 340 without removing the second tank cover 330, thus facilitating maintenance and replacement. The filter element 340 is installed and removed along a length perpendicular to the sewage tank 300. The filter element 340 can be made of HEPA or other components with filtration functions; this application does not specifically limit its application.

[0094] To further improve the separation effect of water vapor and dirt in the sewage tank 300, please refer again to Figure 12. In one feasible embodiment, the third air duct 630 has a first section and a second section, which are a horizontal section and a vertical section, respectively. The vertical section is approximately parallel to the length direction of the sewage tank 300, and the horizontal section is approximately perpendicular to the length direction of the sewage tank 300. The third air duct 630 has a gas-liquid separation plate 640 in the horizontal section and near 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. Thus, when air is drawn from the sewage tank through the third air duct 630, the air in the sewage tank 300 can flow downstream through the gap between the top of the gas-liquid separation plate 640 and the upper part of the horizontal section (see the arrow in Figure 12 for details). Meanwhile, 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 installed in the horizontal section and at the outlet of the third air duct horizontal section, while the gas-liquid separation plate 640 is installed 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 tank 300 being drawn in first passes over the gas-liquid separation plate 640 for gas-liquid separation, and then is filtered by the filter element 340. This reduces the probability of the filter element 340 being contaminated by water vapor and / or dirt, extends the service life of the filter element 340, reduces user operating costs, and also reduces the probability of water vapor condensing into water droplets in the horizontal section of the third air duct.

[0096] Please refer to Figures 2, 14, and 15. In one feasible embodiment, the second bucket lid 330 is provided with a movable locking fastener 380. The front side 112 of the machine body 110, i.e., the front side within the first mounting groove 140, is provided with a locking groove 114 that matches the movable locking fastener 380. The sewage bucket 300 is detachably connected to the machine body 110 by the engagement of the movable locking fastener 380 with the locking groove 114. Specifically, the movable locking fastener 380 may include a flip-up buckle 331 and a spring (not shown). The middle part of the flip-up buckle 331 is hinged to the second bucket lid 330. One end of the flip-up buckle 331 extends out of the outer wall of the second bucket lid 330 and is provided with a downwardly extending fastening part 3311. The other end of the flip-up buckle 331 is provided with an operating part 3312. A spring abuts against the top surface of the flip-up buckle 331 near the engaging part 3311 and between the second bucket lid 330; alternatively, the spring abuts against the bottom surface of the flip-up buckle 331 near the operating part 3312 and between the second bucket lid 330 to drive the engaging part 3311 to flip downwards. The movable locking element may be one, two, or more; this application does not specifically limit this. In this embodiment, a pair of engaging parts 3311 are arranged symmetrically on both sides of the negative pressure port of the second bucket lid, with the negative pressure port as the center.

[0097] In practical applications, the top surface of the sewage tank 300 is a closed surface and perpendicular to the extension direction of the sewage tank, i.e., the top surface of the sewage tank 300 is a plane. When the sewage tank 300 needs to be installed into the first mounting slot 140, the user first tilts and inserts the second docking part 3111 of the sewage tank 300 into the guide section 1212. Then, the sewage tank 300 is rotated about the first mounting platform 120 as the axis of rotation towards the side of the machine body 110. During the rotation, one side of the second docking part 3111 rotates and moves along the bend between the guide section 1212 and the limiting section 1211 and gradually inserts into the limiting section 1211. By allowing the sewage tank 300 to sink a certain distance simultaneously while rotating, it is ensured that the top surface of the sewage tank will not get stuck and unable to rotate due to insufficient distance between it and the bottom surface of the second mounting platform 130. As the sewage tank 300 moves into the first mounting slot 140, the fastening part 3311 is inserted into the locking slot 114 to achieve automatic fastening without user operation. When unlocking, the user presses the operating part 3312, and the fastening part 3311 flips upward to disengage from the fastening state.

[0098] The gap between the top surface of the sewage tank 300 and the bottom surface of the second mounting platform 130 shall not exceed 2 mm, and they shall be parallel to each other. Preferably, the gap between the top surface of the sewage tank 300 and the bottom surface of the second mounting platform 130 shall not exceed 1 mm.

[0099] After the power source 500 draws air from the sewage tank 300, it also needs to expel the corresponding air. To avoid the air expelled by the power source 500 blowing directly at the user and causing discomfort, please refer to Figures 2, 12, and 14. In one feasible embodiment, an exhaust port 1121 is formed on the front surface 112 located in the first mounting groove 140. The exhaust port 1121 is located below the first air vent 611, and the air outlet of the power source 500 is connected to the exhaust port 1121 through the air outlet duct 700. A spacer 360 is provided on the sewage tank 300 or the front surface 112 located in the first mounting groove 140. When the sewage tank 300 is installed in the first mounting groove 140, the spacer 360 is located between the sewage tank 300 and the front surface 112, so that an exhaust gap 350 is formed between the sewage tank 300 and the front surface 112, and the exhaust port 1121 is connected to the exhaust gap 350.

[0100] In this way, the air exhausted from the power source 500 can flow out through the exhaust duct 700 from the exhaust port 1121 and diffuse in all directions along the exhaust gap 350, thus flowing out from the assembly gap between the wastewater tank 300 and the main structure 100. This reduces the impact force of the air exhausted from the power source 500 and changes the direction of the airflow, avoiding user discomfort and improving the user experience. Simultaneously, during use, the wastewater tank 300 can cover the exhaust port 1121, preventing external leakage and improving the aesthetics of the cleaning equipment. Furthermore, since the air flowing out of the exhaust port 1121 directly impacts the wastewater tank 300, the wastewater tank 300 can also reduce the force of the airflow from the exhaust port 1121, further reducing the impact force of the air exhausted from the power source 500.

[0101] In practical applications, when the spacer 360 is located on the sewage tank 300, it can be situated on the side wall of the second tank body 320. The spacer 360 can be integrally designed with the second tank body 320, or it can be a separate design joined by adhesive, heat fusion, or screws; this application does not impose specific limitations on this. When the spacer 360 is located on the front side 112, it can be integrally designed with the body 110, or it can be a separate design joined by adhesive, heat fusion, or screws; this application does not impose specific limitations on this.

[0102] Regarding the specific structure of the floor brush 200, please refer to Figures 16 and 17. In one feasible embodiment, the floor brush 200 may include a housing 210. The housing 210 is connected to the main structure 100 and has a suction port 211. The suction port 211 communicates with the interface on the main structure 100, and a roller brush 240 is installed on the housing 210 at the suction port 211. When the wastewater tank 300 is installed in the first mounting groove 140, the inlet at the bottom of the wastewater tank 300 communicates with the interface, thereby connecting the suction port 211 to the wastewater tank 300. In this way, the negative pressure inside the wastewater tank 300 can be transmitted to the suction port 211 through the connection between the interface and the inlet, so that the dirt generated by the roller brush 240 can be sucked up by the suction port 211 and flow into the wastewater tank 300. In practical applications, the housing 210 is usually also equipped with wheels 250 to assist the floor brush 200 in moving on the surface to be cleaned.

[0103] In one feasible embodiment, the floor brush 200 may further include a scraper spray assembly 220. The scraper spray assembly 220 is assembled from a toothed scraper and a spray plate. In use, the toothed scraper abuts against the roller brush 240. As the roller brush 240 rotates, the toothed scraper can scrape off dirt from the roller brush 240, allowing the dirt to be sucked up by the suction port 211. The toothed scraper can also straighten any hair or tufts of thread tangled on the roller brush 240, making it easier for them to be sucked up by the suction port 211 and preventing hair or tufts of thread from becoming tangled on the roller brush 240.

[0104] However, during long-term use, it was found that the roller brush 240 gradually wears down, causing the comb-tooth scraper to fail to engage with the roller brush 240 and thus fail to perform the aforementioned function. To solve this problem, in one feasible embodiment, the scraper spray assembly 220 is hinged to the housing 210, and the scraper spray assembly 220 is located above the suction port 211. An elastic element 260 is provided between the scraper spray assembly 220 and the housing 210, and the elastic element 260 is used to drive the scraper spray assembly 220 to engage with the roller brush 240. In this way, as the roller brush 240 gradually wears down, the elastic element 260 can drive the scraper spray assembly 220 to always be in contact with the roller brush, thereby ensuring that the comb-tooth scraper of the scraper spray assembly 220 always engages with the roller brush 240.

[0105] In practical applications, the wiper blade water spray assembly 220 can be provided with rotating shafts at both ends, and the wiper blade water spray assembly 220 is rotatably connected to the housing 210 through the rotating shafts at both ends. The elastic element 260 can be a spring, a rubber block, or other components with elastic deformation capabilities.

[0106] In one feasible embodiment, the floor brush 200 may further include an elastic seal 230. The elastic seal 230 has elastic deformation capability and can be made of elastic materials such as rubber or silicone. The elastic seal 230 is connected to the housing 210, located above the suction port 211, and abuts against the bottom of the wiper blade spray assembly 220. Thus, when the wiper blade spray assembly 220 flips and floats relative to the housing 210, the elastic seal 230 always abuts against the bottom of the wiper blade spray assembly 220, thereby always sealing the gap between the wiper blade spray assembly 220 and the upper wall of the suction port 211. This prevents dirt from entering the gap between the wiper blade spray assembly 220 and the upper wall of the suction port 211, affecting the flipping of the wiper blade spray assembly 220, and preventing dirt from accumulating in the gap between the wiper blade spray assembly 220 and the upper wall of the suction port 211 and causing odors.

[0107] Based on the same inventive concept, this application also provides a cleaning device, which includes at least a main structure 100, wherein the main structure 100 has a liquid storage tank and a first mounting platform 120 supporting the liquid storage tank. The bottom of the liquid storage tank has a support portion 310 extending downward and suspended around the outside 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 periphery of the first mounting platform 120. That is, the bottom surface of the support portion 310 is suspended and does not contact other surfaces; specifically, the support portion 310 is suspended around the first outer wall surface 124 of the first mounting platform 120, thus creating a visual effect of "sharing the same bottom surface" with the main structure 100. The support portion 310 can be a hollow structure to communicate with the liquid storage space of the liquid storage tank to expand the liquid storage capacity.

[0109] It should be noted that the specific structures of the main structure 100, the first installation platform 120, the support part 310 and the liquid storage tank can be referred to the contents described in the above embodiments, and will not be repeated here.

[0110] Based on the same inventive concept, this application also provides a cleaning device, which includes at least a main structure 100 and a floor brush 200. The main structure 100 includes a body 110, a liquid storage tank, and a first mounting platform 120 supporting the liquid storage tank. The bottom end of the body 110 is connected to the floor brush 200. The first mounting platform 120 is disposed on the body 110 and extends away from the body 110. The first mounting platform 120 has a first top 122 supporting the liquid storage tank, a first bottom 123 opposite to the first top 122, and a first outer wall surface 124 connecting the first top 122 and the first bottom 123. The liquid storage tank has a support portion 310, which surrounds and forms a mating groove 311. When the liquid storage tank is fixed on the first mounting platform 120, the first mounting platform 120 is embedded in the mating groove 311, and the first outer wall surface 124 is covered by the support portion 310.

[0111] In this embodiment, the support part 310 can cover 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 tank 300, thereby improving the overall aesthetics of the cleaning equipment.

[0112] It should be noted that the specific structures of the main structure 100, the floor brush 200, and the liquid storage tank can be referred to the contents described in the above embodiments, and will not be repeated here.

[0113] The following section will provide a detailed explanation using a floor scrubber as an example, taking a specific application scenario as an example.

[0114] Application Scenario 1:

[0115] The user purchased a specially designed floor scrubber with a matching groove at the bottom of the wastewater tank and a first mounting platform on the front of the machine body that protrudes outward to support the wastewater tank.

[0116] When users install the wastewater tank onto the first mounting platform, they find that the platform is cleverly concealed within a matching groove on the bottom of the tank. Furthermore, the joint edge between the wastewater tank and the platform is subtly positioned below the platform, and the bottom of the tank is suspended in the air. Viewed from the front of the floor scrubber, the wastewater tank and the main structure appear to share a common bottom surface. This design not only effectively avoids exposing the joint line and the first mounting platform but also enhances the overall integrity and aesthetics of the floor scrubber, presenting a more harmonious and consistent visual experience.

[0117] As users continue cleaning, they gradually realize that the clever design of the wastewater tank's bottom surrounds the side wall of the first mounting platform and extends downwards from the top of the platform. This layout not only looks cleaner but also significantly increases the tank's capacity. This allows the floor scrubber to cover a larger cleaning area in a single operation, reducing the frequency of wastewater emptying during cleaning and thus significantly improving cleaning efficiency and user experience.

[0118] Application Scenario 2:

[0119] The user purchased a specially designed floor scrubber. The scrubber's wastewater tank has two downward-extending protrusions or strips at its bottom. The bottom of the first mounting groove on the scrubber, used to accommodate the wastewater tank, has a downward-sloping surface towards the opening of the first mounting groove, and this slope has two trough structures. These trough structures have a unique shape; specifically, each trough structure includes an interconnected limiting section and a guiding section. The guiding section extends upward from the limiting section, and the side of the limiting section closest to the opening of the first mounting groove slopes towards the opening.

[0120] When the user installs the wastewater tank into the first mounting slot, the large opening of the guide section allows the user to easily insert the protrusion into the guide section. Then, guided by the slot structure, the wastewater tank can rotate around the bottom slope of the first mounting slot into the first mounting slot. The limiting section cooperates with the protrusion to accurately assemble the wastewater tank into the first mounting slot. This allows the installation of the storage tank to be completed even if it is not completely aligned, simplifying the alignment process, reducing the cognitive burden and physical operation difficulty for the user during the installation process, and improving the user experience.

[0121] Meanwhile, by rotating the wastewater tank onto the first mounting groove around the bottom inclined surface, the opening of the first mounting groove does not need to be too large relative to the wastewater tank, and it is also convenient to install the liquid storage tank into the first mounting groove. This effectively reduces the assembly gap between the wastewater tank and the first mounting groove, achieves small gap assembly, and improves the overall aesthetics of the floor scrubber.

[0122] Application Scenario 3:

[0123] The user purchased a cleverly designed floor scrubber in which the cleaning solution tank and wastewater tank are cleverly placed on the front of the machine, while the power source responsible for generating powerful suction is located on the back of the machine, right next to the floor brush.

[0124] When a user holds the floor scrubber to clean the floor, the power source is close to the brush, resulting in a lower center of gravity for the machine. This reduces the force required from the user's hand, making it easier and more convenient to operate. The cleaner and wastewater tanks are located on the front of the machine, making them easily visible and allowing the user to monitor their status. This effectively reduces anxiety caused by worrying about the wastewater tank being full or the cleaning solution tank being empty.

[0125] In summary, this floor scrubber is designed with the user experience in mind, making cleaning easier, reducing psychological stress during operation, and improving cleaning efficiency.

[0126] Therefore, the technical solution provided in this application allows the first mounting platform to be embedded into the mating groove of the liquid storage tank, achieving docking and stable support between the liquid storage tank and the first mounting platform. This design allows the liquid storage tank to be conveniently installed on the first mounting platform based on the mating relationship between the mating groove and the first mounting platform, thereby simplifying the user's installation process and improving the accuracy and efficiency of operation. Simultaneously, the upper edge of the first outer wall is not lower than the first bottom surface of the support portion, meaning the downward extension of the support portion exceeds the upper edge of the first outer wall, allowing the support portion to at least partially cover the first outer wall, i.e., at least partially cover the first mounting platform. When the downward extension of the support portion exceeds the lower edge of the first outer wall, the support portion can completely cover the first outer wall of the first mounting platform. Furthermore, this design cleverly transfers the joint line between the first mounting platform and the liquid storage tank from the side of the cleaning equipment to the bottom of the equipment, i.e., a position out of sight under normal use, effectively hiding the joint line between the liquid storage tank and the first mounting platform, creating a visually concealed effect for the first mounting platform, further enhancing the overall appearance and aesthetics of the cleaning equipment.

[0127] Furthermore, the upper edge of the first outer wall is not lower than the first bottom surface of the support, which means that the liquid storage tank is located below the first top of the first installation platform. When the liquid storage tank is a hollow structure and is connected to the water outlet space inside the liquid storage tank, the water storage space of the corresponding liquid storage tank can also extend downward from the top surface of the first installation platform to increase the depth of the liquid storage tank.

[0128] Furthermore, the top surface of the first installation platform is provided with a first docking part, and the bottom end of the liquid storage tank is provided with a second docking part. During the installation of the liquid storage tank onto the main structure, the minimum mating gap between the second and first docking parts decreases. In other words, during the initial docking of the second and first docking parts, the mating gap is relatively large, allowing the user to insert the second docking part into the first docking part even with incomplete alignment. During further docking of the second and first docking parts, the mating gap is smaller, allowing the liquid storage tank to be precisely assembled onto the main structure under the guidance of the second and first docking parts. This allows for installation of the liquid storage tank even with incomplete alignment, simplifying the alignment process, reducing the cognitive burden and physical operational difficulty for the user during installation, and improving the user experience.

[0129] Furthermore, the bottom of the liquid storage tank rotates around the first top as the rotation center, and the top of the liquid storage tank is assembled to the main structure by fitting with the second mounting platform in a planar manner. This allows the opening of the first mounting slot to be less than that of the liquid storage tank, making it easier to install the liquid storage tank into the first mounting slot. In addition, it can effectively reduce the assembly gap between the top of the liquid storage tank and the side of the second mounting platform adjacent to the ground brush, achieving 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, thus placing the center of gravity of the power source close to the floor brush. In other words, when the cleaning equipment is in use, the center of gravity of the power source is positioned closer to the bottom of the cleaning equipment, thereby lowering the overall center of gravity of the cleaning equipment. This significantly reduces the force exerted on the user's hand when pushing the cleaning equipment by holding the top. In other words, the user can move the cleaning equipment with minimal force, improving the grip, facilitating operation, and enhancing the user experience.

[0131] Furthermore, the power source is inverted. When the cleaning equipment is in use, the air inlet of the power source faces downwards. Under the influence of gravity, this reduces the likelihood of water droplets formed from dirt and / or moisture falling directly into the motor and causing damage. Simultaneously, the staggered placement of the air inlet of the power source and the wastewater tank, along with their front-to-back layout, increases the length and number of bends in the air intake duct, improving the water vapor separation effect and further reducing the possibility of dirt and / or moisture being drawn into the power source.

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