Description

Technical Field

[0001] This utility model relates to the field of household cleaning appliance technology, and in particular to a dynamic diaphragm water tank system and cleaning equipment. Background Technology

[0002] With the development of technology and the economy, traditional cleaning methods can no longer meet people's current needs, and cleaning equipment has emerged as a result. For example, vacuum cleaners have the advantages of being lightweight, cordless, and low-noise. To adapt to the different floor cleaning needs in various scenarios, existing cleaning equipment has gradually evolved from the original dry suction to the current cleaning equipment that can add water to wash the floor. A core component of current cleaning equipment with water washing function is the wastewater tank.

[0003] To save design space, existing technologies have adopted a method of dividing the clean water storage area and the wastewater storage area by installing a diaphragm inside the wastewater tank. The deformation of the diaphragm dynamically changes the volume of these two storage areas, thus achieving a dynamic water tank function. However, the dynamic water tank function of existing technologies suffers from problems such as uneven diaphragm deformation, inconsistent deformation directions in different areas, deformation in some areas while remaining unchanged, and asynchronous deformation leading to large-area wrinkles in certain parts of the diaphragm. This results in the water tank's space not being used efficiently, causing the actual capacity of the clean water and wastewater areas to be smaller than expected. Consequently, the dynamic water tank does not fully realize its function, and its space utilization efficiency is insufficient. Therefore, existing dynamic water tank technologies still have many problems that need improvement. Utility Model Content

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0056] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0059] Figures 1-19 This is one or more embodiments of the present utility model.

[0060] like Figures 1-17 As shown, the dynamic diaphragm water tank system 100 includes a water tank body 110, a rigid linkage structure 120, and a suspension and guiding mechanism 130. A flexible diaphragm 111 is installed inside the water tank body 110. The diaphragm 111 can be a flexible and deformable membrane made of biofilm, polymer materials, or synthetic materials. The flexible diaphragm 111 can be a watertight membrane or a unidirectional membrane that allows water to pass through only from the wastewater direction to the clean water direction. The diaphragm 111 can divide the inner cavity 1100 of the water tank into a clean water cavity 1101 and a wastewater cavity 1102, such as... Figure 3 , Figures 5-10 As shown.

[0061] like Figures 3-10 As shown, the rigid linkage structure 120 is fixed to the discrete force transmission region 11120 of the diaphragm 111. In one implementation, the rigid linkage structure 120 can be glued to the diaphragm 111; other fixing methods such as snap-fit ​​or embedding are also possible. Considering the sealing of the clear water chamber and the wastewater chamber, the diaphragm 111 can be divided into a sealed connection region 1111 and a non-sealed connection region 1112, such as... Figure 2 , Figure 4As shown, the sealed connection area 1111 is the part of the diaphragm that needs to be fixed at its end when it is set and fixed in the water tank. The part of the diaphragm that occupies space where it fits with the inner wall of the water tank to fix the diaphragm 111 is the sealed connection area 1111. The sealed connection area 1111 cannot be arbitrarily deformed due to the limitation of the fixing parts of the inner wall of the water tank. The other parts of the diaphragm, that is, the parts that are exposed in the water tank space and can deform, are the non-sealed connection areas 1112. The discrete force transmission area 11120 of the diaphragm 111 is located in the non-sealed connection area 1112. Although there is also a force in the sealed connection area 1111, the deformation of this part does not directly affect the volume change of the clear water chamber and the wastewater chamber, so it is not defined or considered. Therefore, only the discrete force transmission area 11120 is defined in the non-sealed connection area 1112. Because the diaphragm 111 is flexible rather than rigid, the force on each region is related to the deformation of the diaphragm. Since the degree of deformation varies in different regions, the force on each region is different, thus exhibiting a discrete nature. By fixing the rigid linkage structure 120 to the discrete force transmission region 11120 of the diaphragm 111, the strongly correlated discrete force transmission region 11120 formed by the rigid linkage structure 120 covering the diaphragm 111 can be forced to move synchronously and in a coordinated manner. This is equivalent to binding these regions together, enabling these strongly correlated regions to move simultaneously and in the same direction, effectively solving the problem of asynchronous deformation and inconsistent deformation direction in the discrete force transmission region 11120 of the diaphragm 111. The main function of the rigid linkage structure 120 is to force the coordinated movement of the discrete force transmission region 11120 of the diaphragm 111. Because the movement of the diaphragm area covered by the rigid linkage structure 120 indirectly drives the movement of other diaphragm areas not covered by the rigid linkage structure 120, it forces the non-sealed areas 1112 of the diaphragm 111 to move synchronously and cooperatively to the greatest extent possible, thereby maximizing the coordinated movement of all discrete force transmission areas 11120 of the diaphragm 111. The rigid linkage structure 120 can be a plate, such as... Figure 12 , Figure 15 As shown, the plate is placed on the diaphragm; the rigid linkage structure 120 can also be a stiffening beam, such as... Figure 13 As shown, it is also possible to set one or more reinforcing beams on the diaphragm.

[0062] like Figures 3-17As shown, the suspension and guiding mechanism 130 includes a guiding component 131 fixed to the water tank body 100 or the rigid linkage structure 120, and a motion constraint component 132 connecting the water tank body 100 and the rigid linkage structure 120. In some embodiments, the guiding component 131 may be connected to the inner wall of the water tank, fixed to the inner wall of the water tank, rotatably fixed to the inner wall of the water tank, or slidably fixed to the inner wall of the water tank. In other embodiments, the guiding component 131 may also be a slide rail or groove structure provided on the inner wall of the water tank. When the slide rail or groove structure serves as the guiding component 131, it may be detachably provided on the inner wall of the water tank or non-detachably provided on the inner wall of the water tank, for example, by injection molding to form the slide rail or groove, or by bonding, screws, rivets, or other structures to fix the slide rail or groove to the inner wall of the water tank. In other embodiments, the guiding component 131 may also be a fixed structural component or a slide rail or groove provided on the rigid linkage structure 120. The motion constraint 132 connects the water tank body 100 and the rigid linkage structure 120. This connection can be a fixed, rotatable, or slidable connection. Alternatively, the motion constraint 132 can be connected to the rigid linkage structure 120 via other components that are fixedly connected to it; this is equivalent to the motion constraint 132 being connected to the rigid linkage structure.The guide component 131 cooperates with the motion constraint component 132. The movement of the motion constraint component 132 is driven by the liquid level changes in the clear water chamber 1101 and the wastewater chamber 1102 within the water tank body 100. This movement can be caused by the pressure difference between the two chambers due to the liquid level changes, or by the pressure or force exerted by the liquid on the motion constraint component 132, such as buoyancy or gravity. Due to the guiding effect of the guide component 131, the motion constraint component 132 moves along a predetermined path direction designed for its structural function. This movement of the motion constraint component 132 along its predetermined structural function direction, denoted as the Z1 direction, in turn drives the rigid linkage structure 120 to move along the clear water chamber or wastewater chamber towards the compression or extension direction Z2. The Z2 direction, as the predetermined path direction of the rigid linkage structure 120, is influenced by the guide component 131 and the motion constraint component 132. Under the joint constraint of the rigid linkage structure 120, the rigid linkage structure 120 resists deflection outside its predetermined path direction, reduces and lowers the movement of the rigid linkage structure 120 away from its predetermined direction, so that the movement direction of the rigid linkage structure 120 is stably moving towards its predetermined path direction Z2. The movement of the rigid linkage structure 120 along its predetermined path will also carry the diaphragm 111 to move along the predetermined path direction, resisting the deformation of the diaphragm 111 in other directions, reducing the deformation of the diaphragm 111 in other directions. Thus, the rigid linkage structure 120 forces the discrete force transmission area 11120 of the diaphragm 111 to move in coordination and drive the deformation of the diaphragm 111, thereby avoiding the problem of uneven deformation and inconsistent deformation direction of the diaphragm 111, which leads to local wrinkles and other uneven deformation problems. This effectively solves the problem of low space utilization in the dynamic water tank.

[0063] In one embodiment:

[0064] like Figure 3As shown, the suspension and guiding mechanism 130 is a spring mechanism 1301, which includes a guide post 13011 and a spring 13012. In this embodiment, the guiding component 131 is the guide post 13011, which can be fixed to the inner wall of the water tank or to the rigid linkage structure 120. The motion constraint component 132 is the spring 13012, with one end connected to the guide post 13011 and the other end connected to the inner wall of the water tank or the rigid linkage structure 120. This allows the spring to act as a buffer between the inner wall of the water tank and the rigid linkage structure 120. The water level changes in the clear water and wastewater areas of the water tank apply pressure to the spring, causing it to move the rigid linkage structure 120. The rigid linkage structure 120 then drives the coordinated deformation of the discrete force transmission zones of the diaphragm 111. In one embodiment, one end of the spring 13012 is connected to the guide post 13011, and the other end is connected to the rigid linkage structure 120. In order to make the movement of the corners of the rigid linkage structure 120 more coordinated, the spring mechanism 1301 can be arranged in four groups, respectively adjacent to the four corners of the rigid linkage structure 120.

[0065] In another embodiment:

[0066] like Figure 5As shown, the suspension and guide mechanism 130 is a multi-stage folding joint mechanism 1302. The multi-stage folding joint mechanism 1302 includes at least two sections and at least two joint units 13020. A rotating shaft can be provided in the middle to connect the two joint units 13020. Multiple joint units 13020 can also be provided, with the head of each joint unit rotatably connected to the tail of the previous section, and the tail rotatably connected to the head of the next section. Adjacent joint units 13020 are connected in series via rotating shafts. Common rotating shafts can be hinged shafts, but other types of rotating shafts can also be used to connect the units, forming the multi-stage folding joint mechanism 1302. In other embodiments, the multi-stage folding joint mechanism 1302 can also use other connection methods to connect the joints, allowing folding between each level of joint. The first joint unit 13021 of the multi-stage folding joint mechanism 1302 is connected to the inner wall of the water tank through the first connecting end 130210, so that the first joint unit 13021 can be fixed to the inner wall of the water tank or can rotate around the first connecting end 130210. Of course, it can also slide, that is, it can be fixed, hinged, rotated, or sliding. The last joint unit 13022 of the multi-stage folding joint mechanism 1302 is connected to the rigid linkage structure 120 through the last connecting end 130220, and can be fixed, hinged, rotated, or sliding. The guide assembly 131 consists of a first end 130210 and a last end 130220, and the motion constraint 132 consists of a joint unit 13020. The multi-stage folding joint mechanism 1302 undergoes folding or stretching motion under the pressure difference between the liquid in the clear water chamber and the sewage chamber, thereby guiding the rigid linkage structure 120 to move in a predetermined direction, which in turn drives the diaphragm 111 to deform in a preset direction, so that the discrete force transmission areas of the diaphragm 111 deform in synergy.

[0067] In another embodiment:

[0068] like Figures 6-8As shown, the suspension and guiding mechanism 130 includes at least one set of linkage and slide mechanism 1303. The linkage and slide mechanism 1303 includes a connecting rod 13030 and a slide 130300, the slide 130300 including a first slide 1303001. The two ends of the connecting rod 13030 are respectively connected to the inner wall of the water tank and the rigid linkage structure 120, the connection can be a fixed connection, a rotating connection, a sliding connection, etc.; in this embodiment, the guiding component 131 is the first slide 1303001 disposed on the inner wall of the water tank or disposed on the rigid linkage structure 120; the motion constraint member 132 is the connecting rod 13030, the connecting rod 13030 has a sliding end 130301, the sliding end 130301 is slidably connected to the first slide 1303001. In one embodiment, the guide assembly 131 includes a first slide groove 1303001 disposed on the rigid linkage structure 120 and a second slide groove 1303002 disposed on the inner wall of the water tank; the sliding end 130301 of the connecting rod 13030 includes a first sliding end 1303011 and a second sliding end 1303012, the first sliding end 1303011 of the connecting rod 13030 is connected to the first slide groove 1303001, and the second sliding end 1303012 is connected to the second slide groove 1303002. In one embodiment, the motion constraint 132 further includes a first slider 1320, and the sliding end 130301 of the connecting rod 13030 is fixed to the first slider 1320. The first slider 1320 is set in the first slide groove 1303001 and can slide along the first slide groove 1303001. It should be noted that the slider structure is not a necessary feature for the implementation of the solution. Without the slider, the sliding end can still slide in the slide groove without affecting the implementation of the solution. After adding the slider, the sliding end will slide more smoothly in the slide groove, which is reflected in the smoother movement of the rigid linkage structure 120 driving the diaphragm 111.

[0069] Furthermore, in one embodiment, the suspension and guiding mechanism 130 includes at least two sets of linkage sliding mechanisms 1303; the two sets of linkage sliding mechanisms 1303 are respectively connected to different positions on the inner wall of the water tank or the rigid linkage structure; of course, the two sets of linkage sliding mechanisms 1303 can be connected at one end to the same position on the inner wall of the water tank, such as... Figure 9As shown, the function of a dynamic water tank can be achieved by rotating the two ends of the linkage mechanism 120 and connecting them to different positions of the rigid linkage structure. Conversely, the two sets of linkage sliding mechanisms 1303 can also be connected at one end to the same position of the rigid linkage structure via a rotating shaft, while the other ends can be connected to different positions of the inner wall of the water tank. Therefore, the two sets of linkage sliding mechanisms 1303 can be connected to the same position of the rigid linkage structure 120, and the two sets of linkage sliding mechanisms 1303 can be rotatedly connected by hinges or rotating shafts. The parts of the two sets of linkage sliding mechanisms 1303 connected to the inner wall of the water tank are all connected by sliding grooves. This allows the pressure difference between the clear water chamber and the wastewater chamber in the water tank to drive the linkage to move, and the linkage then drives the rigid linkage structure 120 and the diaphragm 111 to move in a preset direction. Of course, the two sets of linkage sliding mechanisms can also be connected to different positions of the inner wall of the water tank and the rigid linkage structure via sliding grooves.

[0070] Further, in one embodiment, the suspension and guide mechanism 130 includes a first link slide mechanism 13031 and a second link slide mechanism 13032. The first link slide mechanism 13031 includes a first link 130311, and the second link slide mechanism 13032 includes a second link 130321. The middle portions of the first link 130311 and the second link 130321 can be pivotally connected, so that the link slide mechanisms are combined to form an X-shaped link slide mechanism, forcing the first link slide mechanism 13031 and the second link slide mechanism 13032 to move synchronously and cooperatively. Figure 10As shown, because the X-shaped link increases the motion constraint end of the rigid linkage structure 120, the movement of the rigid linkage structure 120 becomes more uniform and stable, reducing the possibility of tilting. This makes the deformation movement of the diaphragm 111 more uniform and increases the coordination ability of each region. In the implementation process, the middle part of the link is not strictly the midpoint, but rather the part of the link other than the two ends can be understood as the middle. The middle part of the first link 130311 and the middle part of the second link 130321 are connected by a pivot. In one embodiment, this pivot can be understood as connecting the middle parts of the first link 130311 and the middle parts of the second link 130321 through a rotating shaft or hinge shaft, and realizing the rotation and fixation of the two through the rotating shaft. In another embodiment, the pivot can be understood as penetrating the middle parts of the first link 130311 and the middle parts of the second link 130321 respectively through connecting rods, forcibly connecting the originally separate and unconnected first link 130311. 0311 and the second link 130321 are connected together, so that if one of them moves, the other will also move. In addition, the first link and the second link can rotate around the connecting rod respectively. In other embodiments, the pivot can also be connected by two sleeves to respectively engage the first link 130311 and the second link 130321, and then the two sleeves are connected together by a connecting shaft, so that the first link 130311 and the second link 130321 can rotate around the connecting shaft respectively.

[0071] Furthermore, such as Figures 11-13As shown, in one embodiment, the suspension and guiding mechanism 130 includes at least two sets of linkage sliding mechanisms 1303; the sliding ends 130301 of the at least two sets of linkage sliding mechanisms 1303 are interconnected by a rigid synchronizing member 1304, forcing the connected sliding ends 130301 to move synchronously. It should be noted that the sliding end 130301 of the linkage sliding mechanism 1303 can be a sliding end at only one end of the linkage, or both ends of the linkage can be sliding ends. Furthermore, the rigid synchronizing member 1304 can be welded or connected to the two linkages via a sleeve, or both ends of the rigid synchronizing member 1304 can be rotatably connected to the two linkages respectively. Additionally, a connecting rod can be provided at the sliding ends of the two linkages, which can be detachably connected to the sliding ends of the two linkages, or non-detachably connected, such as integrally formed. In one embodiment, the rigid synchronizing member 1304 can be a connecting rod, sleeve, head, connector, etc. In one embodiment, the suspension and guiding mechanism 130 includes a first link slide mechanism 13031 and a second link slide mechanism 13032, wherein the first link slide mechanism 13031 includes a first link 130311 and the second link slide mechanism 13032 includes a second link 130321. In one embodiment, the first link 130311, the second link 130321, and the rigid synchronizing member 1304 are located in the same plane. This allows the first link 130311, the second link 130321, and the rigid synchronizing member 1304 to better coordinate their movements. The fact that the three are located in the same plane also reduces the space occupied by their connection. Because the three are located in the same plane, they do not occupy space in other planes, which helps to save space and avoid space waste. Of course, in other embodiments, such as the rigid synchronizing member 1304 being rotatably connected to the first link and the second link respectively, it is also possible that the planes formed by any two of the first link 130311, the second link 130321 and the rigid synchronizing member 1304 are not the same plane. The first link slide mechanism 13031 further includes a first sliding end 130310, and the second link slide mechanism 13032 further includes a second sliding end 130320. The first sliding end 130310 and the second sliding end 130320 can be the ends of the link, and their two sliding ends are connected together. However, their presentation is not limited to this form and can also be presented in other forms. For example, in the implementation that includes sliders, the first sliding end 130310 and the second sliding end 130320 can also be the two sliding ends of two sliders connected together. Even in other embodiments, the ends of the link can be connected to the slide through a transition member, so that a sliding end is formed on the transition member, and the sliding ends on the transition member are connected together.In some other embodiments, the first sliding end 130310 and the second sliding end 130320 of the two linkage slide mechanisms are connected together by sleeve (sleeve or sleeve connection), snap-fit, threaded connection, welding or integral molding to form a U-shaped linkage frame 1305, such as. Figure 11 As shown, the first link 130311 and the second link 130321 can be arranged parallel to each other to make the space occupied by the U-shaped linkage frame 1305 as compact as possible to save design space; of course, the first link 130311, the second link 130321 and the rigid synchronizing member 1304 can also be designed on the same plane, so that the first link 130311 and the second link 130321 are not arranged parallel, but the first link 130311 and the second link 130321 are designed as the two hypotenuses of a trapezoid.

[0072] Furthermore, such as Figure 14 , Figure 15As shown, in one embodiment, the sliding ends of the first and second connecting rods are directly connected to form a U-shaped linkage frame 1305. The U-shaped linkage frame 1305 includes a first U-shaped linkage frame 13051 and a second U-shaped linkage frame 13052, wherein the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 are arranged crosswise. Of course, in other embodiments, the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 can be arranged in other ways besides being crosswise, such as side-by-side or parallel. To facilitate the linkage operation of the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052, the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 are chosen to be arranged crosswise, and the two linkage frames can be connected together by a pivot. The first U-shaped linkage frame 13051 has a first U-shaped end 130511, and the second U-shaped linkage frame 13052 has a second U-shaped end 130521. Wherein, at least one of the two free ends of the first U-shaped linkage frame 13051, referred to as the first free end 13051a and the second free end 13051b, is connected to the inner wall of the water tank or the rigid linkage structure 120, and the first U-shaped end 130511 is slidably connected to the rigid linkage structure 120 or the inner wall of the water tank; it can be understood that only one of the two free ends 13051a and 13051b of the first U-shaped linkage frame 13051 can be connected to the inner wall of the water tank or the rigid linkage structure 120, or both of the two free ends 13051a and 13051b of the first U-shaped linkage frame 13051 can be connected to the inner wall of the water tank or the rigid linkage structure 120. In one implementation, the two free ends 13051a and 13051b of the first U-shaped linkage frame 13051 can be connected to the inner wall of the water tank. The connection method can be hinged, rotatable, or sliding. The first U-shaped end 130511 is connected to the rigid linkage structure 120. It can be a sliding connection, which can be achieved by a sliding groove or by a slider. The design can be similar to that of the first U-shaped linkage frame 13051. At least one of the two free ends of the second U-shaped linkage frame 13052, referred to as the third free end 13052a and the fourth free end 13052b, is connected to the inner wall of the water tank or the rigid linkage structure 120. The second U-shaped end 130521 is slidably connected to the rigid linkage structure 120 or the inner wall of the water tank. It can be understood that only one of the two free ends 13052a and 13052b of the second U-shaped linkage frame 13052 can be connected to the inner wall of the water tank or the rigid linkage structure 120. Of course, both free ends 13052a and 13052b of the second U-shaped linkage frame 13052 can be connected to the inner wall of the water tank or the rigid linkage structure 120.In one implementation, the two free ends 13051a and 13051b of the second U-shaped linkage frame 13052 can be connected to the inner wall of the water tank, and a sliding connection can be selected; the second U-shaped end 130521 is connected to the rigid linkage structure 120, and a sliding connection can be selected. The sliding connection can be achieved by means of a sliding groove, or by means of a slider transition, etc.

[0073] To enable the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 to interact and move synchronously, their respective arched portions, namely the first arched portion 13051c and the second arched portion 13052c, can be rotatably connected by a pivot. Figure 15 As shown, the connection can be hinged, pivotal, or connected by a rigid rod, allowing the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 to rotate around the rigid rod. These methods form the linkage node, enabling the first U-shaped linkage frame 13051 and the second U-shaped linkage frame 13052 to work in tandem, influencing each other and preventing deformation of the diaphragm's discrete force transmission area caused by each linkage frame driving its own rigid linkage structure 120, or asynchronous movement due to a lack of direct linkage between them, thus avoiding diaphragm malfunction. The problem of localized wrinkles caused by asynchronous deformation in different force transmission zones of the membrane is addressed by this solution. The pressure difference generated by the change in liquid level between the clear water and wastewater chambers of the water tank causes the first U-shaped linkage 13051 and the second U-shaped linkage 13052 to work in tandem. This tandem operation allows the rigid linkage structure areas driven by the first U-shaped linkage 13051 and the second U-shaped linkage 13052 to work collaboratively. Since the first U-shaped linkage 13051 and the second U-shaped linkage 13052 may be connected to different parts of the rigid linkage structure, this is achieved by creating linkage nodes between the first U-shaped linkage 13051 and the second U-shaped linkage 13052 to enable these different rigid linkage structure areas to move collaboratively, thus driving the diaphragm's discrete force transmission zones at different locations.

[0074] Furthermore, such as Figure 16 , Figure 17As shown, in one embodiment, the two free ends 13051a and 13051b of the first U-shaped linkage 13051 are connected to the inner wall of the water tank via the first inner wall sliding groove 13053 and the second inner wall sliding groove 13054, respectively, while the two free ends 13052a and 13052b of the second U-shaped linkage 13052 are rotatably connected to the inner wall of the water tank via rotating shafts. In another embodiment, the two free ends 13051a and 13051b of the first U-shaped linkage 13051 are connected to the inner wall of the water tank via the first inner wall sliding groove 13053 and the second inner wall sliding groove 13054, respectively; the two free ends 13052a and 13052b of the second U-shaped linkage 13052 are slidably connected to the inner wall of the water tank via the third inner wall sliding groove 13055 and the fourth inner wall sliding groove 13056, respectively. The first inner wall sliding groove, the second inner wall sliding groove, the third inner wall sliding groove, and the fourth inner wall sliding groove are all forms of sliding grooves.

[0075] Furthermore, in order to better limit the movement direction of the first U-shaped linkage 13051 and the second U-shaped linkage 13052 and prevent their respective movement directions from deviating, and also to reduce the resistance of the sliding groove on the sliding of the first U-shaped linkage 13051 and the second U-shaped linkage 13052, the sliding connection between the first U-shaped end 130511 and the rigid linkage structure 120 or the inner wall of the water tank can be achieved by parallel shallow grooves 130100, such as... Figure 12 , Figure 13 , Figure 15 As shown, the first U-shaped end 130511 and the second U-shaped end 130521 can be selectively disposed on the rigid linkage structure 120 or the inner wall of the water tank. The number of shallow grooves 130100 can be two or more, and the width of the shallow groove 130100 should not exceed one-third of the width of the first U-shaped end 130511 or the second U-shaped end 130521. The sliding connection between the second U-shaped end 130521 and the rigid linkage structure 120 or the inner wall of the water tank is also achieved through the parallel shallow grooves 130100.

[0076] This solution also provides a cleaning device 200, which has a dynamic diaphragm water tank system 100 according to one of the above embodiments. The cleaning device 200 can be a floor scrubber, cleaning robot, countertop cleaner, or kitchen surface cleaner, or other cleaning device with a water washing function. Figure 18 , Figure 19 As shown, a floor scrubber equipped with the aforementioned dynamic diaphragm water tank system 100.
