Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically to a cleaning device. Background Technology

[0002] Existing cleaning equipment, especially floor scrubbers, first sprays liquid, then uses a brush to roll and clean the stains on the floor, and finally uses vacuum negative pressure to collect the dirty liquid into a wastewater tank. However, to facilitate the removal of the wastewater tank, a recess is needed in the tank lid for users to lift it by hand. However, this recess affects the overall appearance of the cleaning equipment, and over time, it can easily become a hard-to-clean, unsanitary corner. A similar technology can be found in Chinese utility model patent CN221105736U. There are also solutions in the industry that use a raised lid for the wastewater tank, but this also affects the appearance, and the inside of the raised lid can easily become a hard-to-clean, leading to a poor user experience. Therefore, improvements are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device that, through the rotation design of the rotating plate, has an internal operating space, which facilitates the placement and removal of the sewage tank and reduces the occupation of external space. At the same time, it keeps the exterior surfaces of the cleaning device coplanar, making it easy to clean, leaving no dead corners for hygiene, and facilitating the disassembly of the sewage tank.

[0004] To achieve the objective of this invention, a cleaning device is provided, comprising a body; a wastewater tank detachably connected to the body; and a rotating plate rotatably connected to the body, with the rotating plate positioned above the wastewater tank along the height direction of the body. When the rotating plate rotates from a first position to a second position, an operating space is formed at one end of the rotating plate near the top of the wastewater tank, facilitating the placement and removal of the wastewater tank based on the operating space.

[0005] Based on the first technical solution, the following supplementary technical solutions are further included: Furthermore, when the rotating plate is in the first position, the outer surface of the rotating plate is coplanar with the outer surface of the machine body, so that the entire outer surface of the product can be cleaned without obstruction, avoiding the problem of hygiene dead corners caused by surface unevenness.

[0006] Furthermore, the cleaning equipment also includes a locking frame, one end of which is rotatably connected to the rotating plate, and the other end of which can be locked or released from the top of the sewage tank. When the rotating plate is in the first position, the other end of the locking frame is locked to the top of the sewage tank, so that the top of the sewage tank can be locked or released by changing the rotation position. The sewage tank can be unlocked by the locking frame, which not only maintains the coplanar appearance of the cleaning equipment and makes it overall coordinated, but also facilitates cleaning, leaves no dead corners for hygiene, and facilitates the disassembly of the sewage tank.

[0007] Furthermore, the sewage tank includes a sewage tank body and a sewage tank cover connected to the sewage tank body, wherein the sewage tank cover includes a locking groove that engages with the other end of the locking frame; wherein the rotating plate has a rotating shaft and a supporting surface, the rotating plate rotates around the rotating shaft, and when in the second position, the supporting surface drives one end of the locking frame to rotate, and releases the other end of the locking frame from the locking groove, so as to release the engagement between the locking frame and the locking groove by the movement of the supporting surface.

[0008] Furthermore, the cleaning device also includes a mounting base that mates with the rotating plate, wherein the mounting base includes a support block that can at least partially accommodate the rotating shaft to support effective rotation of the rotating shaft.

[0009] Furthermore, the rotating plate includes a plate connecting part located on the inner side and a plate protrusion connected to the plate connecting part and located on the inner side. The rotating shaft and the supporting surface are both disposed on the plate protrusion. The supporting surface is located above the plate connecting part and below the center of the rotating shaft. Through the design of the supporting surface, the rotating structure is optimized and the frame lock arm is reliably unlocked.

[0010] Furthermore, the plate protrusion has a connecting block connected to the plate connecting part, wherein the rotating shaft is located above the connecting block, and the rotating shaft and the connecting block partially overlap on the same projection plane. By having the rotating shaft and the connecting block partially overlap on the same projection plane, a compact structure and ease of rotation are achieved.

[0011] Furthermore, the plate protrusions are at least a pair and are spaced apart; wherein the rotating plate has a rotating outer surface extending on a plane, wherein the plane containing the rotating outer surface is parallel to the axial direction of the rotating shaft and perpendicular to the protrusion direction of the plate protrusions. By designing the relative directions of the rotating plate and the plate protrusions, the fit between the two is optimized and the structure is simplified.

[0012] Furthermore, it also includes a panel frame connected to one side of the fuselage and disposed perpendicular to the ground, wherein the panel frame includes a panel receiving block that at least partially houses the rotating shaft and is disposed corresponding to the support block, so that the effective rotation of the rotating shaft is supported by both the support block and the panel receiving block.

[0013] Furthermore, it also includes a torsion spring fitted onto the rotating shaft and providing a restoring force to return the rotating shaft to its pre-operational position.

[0014] Furthermore, the fixing seat includes a base body, a flat plate portion disposed on the base body, and a limiting groove disposed on the flat plate portion and adjacent to the support block, wherein the limiting groove at least partially accommodates the protruding portion of the plate; wherein the locking frame includes a frame base located above the limiting groove, a pair of frame connecting bodies with one end connected to the frame base body, and a pair of frame locking arms with one end connected to the corresponding frame connecting body. Through the linkage structure of the rotating plate, the fixing seat, and the locking frame, the rotation method can ensure reliable unlocking of the sewage tank in the vertical direction.

[0015] Furthermore, there are two plate sections located on both sides of the base body, and each plate section also includes a support block spaced apart from the support block. The limiting groove is located between the support block and the support block, and both the support block and the support block are provided with arc-shaped grooves that can partially accommodate the rotating shaft. Through the arc-shaped groove design of the support block and the support block, the rotating shaft can be accommodated and allowed to rotate, ensuring reliable rotation.

[0016] Furthermore, the fixing base also includes a limiting block located below the base body and corresponding to the limiting groove, and a fixing post disposed on the flat plate. The limiting block limits the position of the plate protrusion to prevent excessive rotation.

[0017] Furthermore, the locking frame also includes a base fixing block disposed on the frame base and an elastic element fixed at one end to the base fixing block, wherein the elastic force direction of the elastic element is perpendicular to the ground, and the position of the base fixing block is reset by the elastic element to ensure the continuity of the action.

[0018] Furthermore, the panel frame includes an outer panel surface, a panel hole located below the outer panel surface, a panel fixing bracket located inside the outer panel surface, a panel connecting post adjacent to the panel receiving block, and a panel fixing block corresponding to the base fixing block. The panel receiving block extends downward from the panel fixing bracket and is provided with a receiving block groove that can accommodate the rotating shaft, thereby supporting the effective rotation of the rotating shaft.

[0019] The advantages of this invention are as follows: By setting a rotating plate that can rotate relative to the main body, and when the rotating plate rotates to the second position, an operating space is formed on top of the sewage tank for the user to place and retrieve the sewage tank, which effectively improves the convenience of the user in placing and retrieving the sewage tank. Furthermore, this application achieves unlocking and locking of the sewage tank through the rotation of the rotating plate. Compared to the prior art where the sewage tank needs to be manually tapped by the user to be installed, this reduces damage to the locking device and effectively provides a smoother installation of the sewage tank, improving the user experience. It also reduces the occupancy of external space. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0024] This invention provides a cleaning device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this invention. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0025] like Figure 1-8As shown, the present invention provides a first embodiment of a cleaning device, which is vertically arranged on the ground and includes: a body 1000, a wastewater tank detachably connected to the body 1000, and a rotating plate 4200 rotatably connected to the body 1000. A fixed base 4400 connected to the rotating plate 4200, a locking frame 4600 pulsatorically connected to the rotating plate 4200, a panel frame 1200 connected to one side of the body 1000, a back plate 1400 connected to the other side of the body 1000, and a wastewater tank located within the body 1000, wherein the rotating plate 4200 is along the height direction of the body 1000 and is located above the wastewater tank. When the rotating plate 4200 rotates from a first position to a second position, the end of the rotating plate 4200 near the top of the wastewater tank flips inward to form an operating space, facilitating the placement and removal of the wastewater tank based on the operating space.

[0026] This application incorporates a rotating plate 4200 that can rotate 1000 degrees relative to the main body. When the rotating plate 4200 rotates to its second position, it creates an operating space on top of the sewage tank for the user to place and retrieve the sewage tank, effectively improving the convenience of the user in handling the sewage tank. Furthermore, this application uses the rotation of the rotating plate 4200 to unlock and lock the sewage tank. Compared to existing technologies where the user needs to manually tap the sewage tank to install it, this reduces damage to the locking device and provides a smoother installation experience, enhancing the user experience. It also reduces the amount of external space occupied.

[0027] Furthermore, the present application achieves the unlocking or locking of the sewage tank and the machine body by rotating the rotating plate 4200. Compared with the prior art, which uses a structure such as a handle to unlock or lock the sewage tank, this avoids the formation of protrusions or gaps on the surface of the sewage tank. This avoids the unevenness of the overall outer surface of the machine body 1000 and also avoids the problem of dust accumulation in the corresponding position of the machine body due to the protrusions or gaps.

[0028] Specifically, when the rotating plate 4200 rotates from the first position to the second position, the end of the rotating plate 4200 near the top of the sewage tank moves laterally inward by 15-25mm, so that the user's fingers can reach into the operating space to pick up or put down the sewage tank.

[0029] Preferably, the distance of lateral inward movement can be 20mm.

[0030] In some embodiments, when the rotating plate 4200 is in the first position, the outer surface of the rotating plate 4200 can be coplanar with the outer surface of the body 1000; so that the overall outer surface of the body is smooth and there are no obvious protrusions or gaps, which can not only avoid dust accumulation at protrusions or gaps, but also improve the overall aesthetics.

[0031] Specifically, the outer surface of the rotating plate 4200 can be coplanar with the outer surface of the body 1000, or the outer surface of the rotating plate 4200 and the outer surface of the body 1000 can be located in the same plane; or the outer surface of the rotating plate 4200 and the outer surface of the body 1000 can be smoothly transitioned.

[0032] In other embodiments, when the rotating plate 4200 is in the first position, the outer surface of the rotating plate 4200 can also be coplanar with the outer surface of the sewage tank, which can also make the overall outer surface of the machine body smooth and without obvious protrusions or gaps.

[0033] Specifically, the outer surface of the rotating plate 4200 can be coplanar with the outer surface of the sewage tank, or the outer surface of the rotating plate 4200 and the outer surface of the sewage tank can be located in the same plane; or the outer surface of the rotating plate 4200 and the outer surface of the sewage tank can be smoothly transitioned.

[0034] In some embodiments, a locking frame 4600 is also included, one end of which is rotatably connected to the rotating plate 4200, and the other end is capable of locking or releasing with the top of the sewage tank. When the rotating plate 4200 is in the first position, the other end of the locking frame 4600 is locked with the top of the sewage tank.

[0035] Specifically, as the rotating plate 4200 rotates from the first position to the second position, it drives one end of the locking frame 4600 to move, causing the other end of the locking frame 4600 to move upward. When the rotating plate 4200 rotates to the second position, the other end of the locking frame 4600 separates from the sewage tank, thus unlocking the sewage tank. This linkage unlocking method is simple and easy to operate, and makes the removal and replacement of the sewage tank very smooth, effectively improving the user experience.

[0036] The fuselage 1000 includes a sewage tank cavity 1020 for accommodating a sewage tank, and a receiving cavity 1040 located above the sewage tank cavity 1020 for accommodating a rotating plate 4200, a fixed base 4400, and a locking frame 4600. The two ends of the receiving cavity 1040 are defined by a panel frame 1200 and a back plate 1400.

[0037] For reference Figure 8As shown, the panel frame 1200 includes a panel outer surface 1204, a panel hole 1220 located below the panel outer surface 1204, a panel fixing bracket 1240 located inside the panel outer surface 1204, a panel receiving block 1260 extending downward from the panel fixing bracket 1240 and at least partially receiving the rotating shaft 4242, a panel connecting post 1270 disposed adjacent to the panel receiving block 1260 and corresponding to the fixing post 4444, and a panel fixing block 1280 corresponding to the base fixing block 4660. In some embodiments, the panel receiving block 1260 is provided with an arc-shaped receiving block groove 1264 that can receive the rotating shaft 4242, thereby ensuring effective rotation of the rotating shaft. The panel connecting post 1270 and the fixing post 4444 are fixedly connected by screws. An elastic member 4900 is provided between the base fixing block 4660 and the panel fixing block 1280 to realize the position reset of the base fixing block 4660 and ensure continuous operation.

[0038] like Figure 5-6 As shown, a wastewater tank is located within a wastewater tank cavity 1020 and includes a wastewater tank body 2000 with a wastewater inlet 2004 and a wastewater tank cover 2400 connected to the wastewater tank body 2000. The wastewater tank body 2000 includes an inner wastewater tank cavity 2020 located therein, an outer wastewater tank surface 2040 located on the outside, a wastewater inlet pipe 2060 located within the inner wastewater tank cavity 2020 and connected at one end to the wastewater inlet 2004, an air inlet / outlet assembly 3000 located within the inner wastewater tank cavity 2020 and connected to the wastewater inlet pipe 2060, and a separator 3200 disposed on the air inlet / outlet assembly 3000. Water-air separation is achieved through the wastewater inlet pipe 2060, the air inlet / outlet assembly 3000, and the separator 3200. The wastewater tank cover 2400 includes an outer surface 2404 on the outer side, a handle groove 2408 on the inner side adjacent to the outer surface 2404, a wastewater tank cover opening 2420 for air outlet, and a latch groove 2440 on the inner side that engages with the other end of the frame latch arm 4640. In some embodiments, the outer surface 1204 of the panel, the rotating outer surface 4204, and the outer surface 2404 of the cover are all on the same surface. This can be achieved by placing the outer surface 1204 of the panel, the rotating outer surface 4204, and the outer surface 2404 of the cover in the same plane, more preferably, on the same plane. Furthermore, the outer surface 1204 of the panel, the rotating outer surface 4204, and the outer surface 2404 of the cover can be smoothly transitioned, resulting in a smooth overall outer surface of the unit without any obvious protrusions or gaps. To further filter impurities and water in the airflow, the wastewater tank cover 2400 further includes a filter element 2600 located within the wastewater tank cover opening 2420. The filter element 2600 is a combination of HEPA and sponge, or a high-grade sponge. A handle for easy gripping is located on the top of the wastewater tank, opposite the clearance space.

[0039] like Figure 2 As shown, the rotating plate 4200 includes an outer rotating surface 4204, an inner plate connecting portion 4220, and an inner plate protrusion 4240 connected to the plate connecting portion 4220. The plate protrusion 4240 has a rotating shaft 4242 and a supporting surface 4245, and the rotating plate 4200 rotates about the rotating shaft 4242. The supporting surface 4245 is located above the plate connecting portion 4220 and below the center of the rotating shaft 4242. There are at least one pair of plate protrusions 4240, spaced apart. The rotating plate 4200 has an outer rotating surface 4204 extending in a plane, the plane of which is parallel to the axial direction of the rotating shaft 4242 and perpendicular to the protrusion direction of the plate protrusion 4240. The design of the rotating plate and the plate protrusion in opposite directions optimizes their fit and simplifies the structure. The plate protrusion 4240 has a connecting block 4246 connected to the plate connecting portion 4220. The rotating shaft 4242 is located above the connecting block 4246, and the rotating shaft 4242 and the connecting block 4246 partially overlap on the same projection plane. This partial overlap of the rotating shaft and the connecting block on the same projection plane achieves a compact structure and facilitates rotation. The plate protrusion 4240 also includes a protruding end face 4244 connected to the support surface 4245, wherein the plane containing the protruding end face 4244 is perpendicular to the horizontal plane. When the rotating plate rotates to the second position, an operating space is formed on the top of the sewage tank for the user to place and retrieve the sewage tank, effectively improving the convenience of the user in placing and retrieving the sewage tank. When the rotating plate 4200 rotates around the rotating shaft 4242, the plate protrusion 4240 drives the frame base 4620 to rotate, releasing the latch between the frame locking arm 4640 and the locking groove 2440. Thus, the rotating plate 4200, the fixed base 4400, and the locking frame 4600 work together to ensure that the sewage tank can be reliably unlocked in the vertical direction by rotation.

[0040] like Figure 3As shown, the fixing base 4400 includes a base body 4420, a flat plate portion 4440 disposed on the base body 4420, a support block 4470 disposed on the flat plate portion 4440 and capable of at least partially accommodating a rotating shaft 4242, a limiting groove 4460 disposed on the flat plate portion 4440 and adjacent to the support block 4470, a limiting block 4464 located below the base body 4420 and corresponding to the limiting groove 4460, and a fixing post 4 disposed on the flat plate portion 4440. 444, wherein the limiting groove 4460 at least partially accommodates the protruding portion 4240 of the plate; two flat plates 4440 are preferably located on both sides of the base 4420, and each flat plate 4440 further includes a support block 4474 spaced apart from the support block 4470, wherein the limiting groove 4460 is located between the support block 4474 and the support block 4470, and both the support block 4470 and the support block 4474 are provided with an arc-shaped groove 4476 that can partially accommodate the rotating shaft 4242. One end of the support block 4474 and the support block 4474 are provided with a support block end face 4478 defined by the limiting block 4464.

[0041] like Figure 1 , 7 As shown, the locking frame 4600 includes a frame base 4620 located above the limiting groove 4460, a pair of frame connectors 4630 connected to the frame base 4620 at one end, a pair of frame locking arms 4640 connected to the corresponding frame connectors 4630 at one end, a base fixing block 4660 disposed on the frame base 4620, and an elastic member 4900 fixed at one end to the base fixing block 4660, wherein the other end of the frame locking arm 4640 is in a locked state; wherein when the rotating plate 4200 rotates around the rotating axis 4242, the supporting surface 4245 of the plate protrusion 4240 drives the frame base 4620 to rotate and releases the locking of the frame locking arm 4640. Through the linkage structure of the rotating plate, the fixing seat, and the locking frame, the rotation method can ensure reliable unlocking of the sewage tank in the vertical direction. The frame base 4620 is located between the limiting block 4464 and the support block 4470, and the frame base 4620 and the frame connector 4630 extend on the same horizontal plane, while the extension direction of the frame locking arm 4640 is perpendicular to this horizontal plane. One end of the locking frame 4600 is rotatably connected to the rotating plate 4200, and the other end can be locked or released from the top of the sewage tank. When the rotating plate 4200 is in the first position, the other end of the locking frame 4600 is locked to the top of the sewage tank. The rotating plate 4200 rotates about the rotating shaft 4242, and when it is in the second position, the support surface 4245 drives one end of the locking frame 4600 to rotate, releasing the other end of the locking frame 4600 from the locking groove 2440.

[0042] Based on the above embodiments, the unlocking principle of the wastewater tank of the cleaning equipment of the present invention is as follows: When a user needs to remove the wastewater tank of the cleaning equipment: the user can manually push the rotating plate 4200 set on the machine body 1000, so that the end of the rotating plate 4200 near the wastewater tank rotates inward. When the rotating plate 4200 rotates to the second position, the wastewater tank cover 2400 and the locking frame 4600 are unlocked, and an operating space is formed on the top of the wastewater tank. Furthermore, the user can use the operating space to grab the wastewater tank and remove it.

[0043] As the user moves away, the rotating plate 4200 automatically resets to the first position.

[0044] Furthermore, when the user needs to return the wastewater tank of the cleaning equipment: the user can manually push the rotating plate 4200 set on the machine body 1000, so that the end of the rotating plate 4200 near the wastewater tank rotates inward. When the rotating plate 4200 rotates to the second position, the locking frame 4600 moves upward, and at the same time, an operating space is formed on the top of the wastewater tank. Furthermore, the user puts the wastewater tank into the wastewater tank cavity 1020 through the operating space. As the user moves away, the rotating plate 4200 automatically returns to the first position. At this time, the locking frame 4600 moves downward to lock with the top of the wastewater tank cover 2400, thereby limiting the position of the wastewater tank.

[0045] Therefore, this invention, by incorporating a rotating plate that can rotate relative to the main body, creates an operating space on top of the sewage tank when the plate rotates to a second position, allowing the user to easily access and place the sewage tank. This effectively improves the convenience of accessing and placing the sewage tank. Furthermore, this application uses the rotation of the plate to unlock and lock the sewage tank. Compared to existing technologies where the user needs to manually tap the sewage tank to install it, this reduces damage to the locking device and provides a smoother installation experience, enhancing the user experience. It also reduces the amount of external space required.

[0046] The present invention provides a detailed description of a cleaning device. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, those skilled in the art will recognize that there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
