Description

Technical Field

[0001] This invention relates to the technical field of cleaning equipment, and more particularly to a water pump assembly and a floor scrubber. Background Technology

[0002] When the water pump assembly malfunctions, the complex internal water piping and numerous power and signal cables often force users to send the entire floor scrubber back to the manufacturer for repair. Since most water pump assemblies are integrated units, removing the damaged pump from within is difficult, requiring specialized tools to disassemble the assembly's casing. Furthermore, the numerous electrical and water connections between the water pump assembly and the floor scrubber body contribute to the inefficiency of installing and maintaining the water pump assembly during manufacturing. Summary of the Invention

[0049] The claims of the present invention will be further described in detail below with reference to specific embodiments and 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 also within the scope of protection of the present invention.

[0050] It should be understood that, in the description of the embodiments of the present invention, all directional indicating terms, such as "up," "down," "left," "right," "front," and "back," indicate the orientation or positional relationship based on the orientation and positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product is in use. These terms are merely for the purpose of simplifying the description of the present invention and do not explicitly or implicitly suggest that the device, element, or component referred to must have a specific orientation or specific orientational structure, and should not be construed as a limitation of the present invention. They are only used to explain the relative positional relationships and movements between the components shown in the accompanying drawings. When this specific orientation changes, the directional indication may also change accordingly.

[0051] Furthermore, in this invention, ordinal numbers such as "first" and "second" are used for distinguishing purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Thus, the features referred to as "first" and "second" may explicitly or implicitly include at least one of those technical features. In the description of this invention, "a plurality of" means at least two, i.e., two or more, unless otherwise explicitly defined; "at least one" means one or more.

[0052] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "screw-in" should be interpreted broadly. For example, they can refer to a relatively fixed positional relationship between components, or a physically fixed connection between components; they can be detachable connections or integral structures; they can be mechanical connections or electrical signal connections; they can be direct connections or indirect connections through intermediate media or components; they can refer to the internal communication of two elements or the interaction between two elements. Unless otherwise explicitly limited in the specification, other interpretations will not achieve the corresponding functions or effects. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0053] To address the technical problem that many existing water pump assemblies are integrated units, making it difficult to remove damaged pumps from within, often requiring specialized disassembly tools to remove the pump assembly casing and resulting in unnecessary disassembly procedures for manufacturers, such as... Figure 1-4As shown, this embodiment of the invention provides a water pump assembly. When the water pump 1 is damaged, the sealing assembly 3 is removed from the large end opening of the mounting housing 2, and the end cover 4 is removed from the small end opening of the mounting housing 2. The entire mounting housing 2 can then be removed. This disassembly process is convenient and reduces unnecessary disassembly procedures for manufacturers.

[0054] In a first aspect, embodiments of the present invention provide a specific structure of a water pump assembly 100, according to the appendix. Figure 2-11 As shown, the water pump assembly 100 specifically includes a water pump 1, a mounting housing 2 for housing and mounting the water pump 1, a sealing component 3 that seals the water pump 1 inside the housing 2 from one end, and an end cap 4 covering the end of the housing 2 from the other end. The water pump 1 has an inlet and outlet end (not shown in the figure) located at its bottom and two power electrodes (not shown in the figure) located at its top. Both ends of the mounting housing 2 have openings of different sizes, and the side wall of the smaller opening end near the power electrodes has two power sockets / pins a1 and a2 that are electrically connected to the power electrodes to supply power to the water pump 1. The sealing component 3 seals the water pump 1 inside the mounting housing 2 and can be detachably inserted into the larger opening end of the mounting housing 2. After the water inlet and outlet directions of the water pump 1 are vertically turned, it passes through two through holes 23 and 24 on one side of the mounting housing 2. When disassembling the mounting housing 2, the sealing component 3 is removed from the larger end of the mounting housing 2. When assembling the mounting housing 2, the sealing component 3 is directly and elastically pressed into place after facing the larger opening end of the mounting housing 2. In addition, the sealing component 3 is sealed to the inlet and outlet of the water pump 1 to prevent water leakage into the interior of the floor scrubber, which could damage the internal electronic structure of the floor scrubber. The end cap 4 is detachably disposed at the wiring cavity end of the second end of the mounting housing 2. The two power sockets / pins are aligned with the two through holes. Unlike traditional mounting housings, the end cap 4 of this embodiment can be removed from the small end opening of the mounting housing 2. When the manufacturer needs to replace the power socket / pin that supplies power to the water pump 1 located inside the end cap 4, the damaged power socket / pin can be removed from the mounting housing 2 after the end cap 4 is removed from the small end opening. When the water pump 1 inside the mounting housing 2 is damaged and needs to be replaced, the user only needs to remove the sealing component 3 from the large end opening of the mounting housing 2 to remove the water pump 1. After replacing the water pump 1 inside the mounting housing 2, the end sealing component 3 is reassembled into the large end opening of the mounting housing 2. The process of replacing the water pump 1 as a whole is very convenient.

[0055] In one or more alternative embodiments, such as Figure 5 , Figure 7 , Figure 10As shown, one end of the sealing assembly 3 is provided with a recess 35 that accommodates and elastically seals against the inlet and outlet ends of the water pump 1. One side of the sealing assembly 3 is provided with an inlet protrusion 31 and an outlet protrusion 32 that respectively connect to the inlet portion 11 and the outlet portion 12 of the water pump 1. The inlet protrusion 31 and the outlet protrusion 32 are respectively elastically sealed against the two through holes 23 and 24 of the mounting housing 2. Further, as... Figure 7 As shown, the sealing component 3 is made of elastic material. The two ends of the peripheral wall near the two ends of the sealing component 3 are provided with upward protruding sealing ribs. This helps to increase the sealing effect of the sealing component 3 on the water pump 1 in the mounting housing 2 and can prevent water from leaking out from the gap between the sealing component 3 and the mounting housing 2.

[0056] In one or more alternative embodiments, such as Figures 5 to 7 , Figure 9As shown, the sealing assembly 3 is provided with a first drain pipe 33 and a second drain pipe 34. The first end (vertical section) of the first drain pipe 33 is connected to the water inlet 11 of the water pump 1, and the second end (horizontal section) of the first drain pipe 33 is connected to the water inlet boss 31. The first end (vertical section) of the second drain pipe 34 is connected to the water outlet 12 of the water pump 1, and the second end (horizontal section) of the second drain pipe 34 is connected to the water outlet boss 32. At the bottom end of the water pump 1, there are an inlet section 11 and an outlet section 12 pointing outward from the bottom end. The inlet section 11 has an inlet channel for entering the water pump, and the outlet section 12 has an outlet channel for flowing out of the water pump. On the end face of the recess 35, in the direction pointing inward from the sealing assembly 3, there are also vertical portions of the first drain pipe 33 and the second drain pipe 34 that can be elastically connected to and accommodate the inlet section 11 and the outlet section 12 respectively. The vertical portions of the first drain pipe 33 and the second drain pipe 34 are both inside the sealing assembly 3, respectively turning vertically towards the inlet boss 31 and the outlet boss 32 and extending outward through the inlet boss 31 and the outlet boss 32 respectively. The height of the inlet boss 31 and the outlet boss 32 above the side of the sealing component 3 is higher than the height of the sealing rib on the periphery of the sealing component 3 above the side of the sealing component 3. The height difference between the inlet boss 31 and the outlet boss 32 and the sealing rib on the periphery of the sealing component 3 is greater than or equal to the wall thickness of the mounting housing 2 in the areas of the two through holes 23 and 24. This ensures that the entire water pump assembly can more fully and elastically contact the water inlet B1 and the water outlet B2 of the floor scrubber body 200 when it is installed into the floor scrubber body 200. This ensures that the water inlet B1 and the water outlet B2 can be more fully inserted into the first drain pipe 33 and the second drain pipe 34 of the inlet boss 31 and the outlet boss 32. The part of the elastic inlet boss 31 and the outlet boss 32 that is higher than the mounting housing 2 can quickly extend and fill the gap between the mounting housing 2 and the floor scrubber body 200 by utilizing its own elasticity. Meanwhile, the floor scrubber body 200 is also equipped with positive electrode A1 and negative electrode A2 that cooperate with the power socket / pins a1 and a2 of the water pump assembly 100. When the user removes or installs the water pump assembly 100 onto the floor scrubber body 200 at one time, the electrical connection and water connection of the water pump assembly 100 can be disconnected or connected at one time, which improves the efficiency of maintenance.

[0057] In one or more alternative embodiments, such as Figure 6 , Figure 7 , Figure 9 , Figure 10As shown, the second end (horizontal section) of the first drainage pipe 33 is a channel perpendicular to the first end (vertical section) that passes through the inlet protrusion 31 and its adjacent side end. A first sealing plug 36 is provided on the adjacent side end of the inlet protrusion 31 to prevent water from flowing out from that side. The second end (horizontal section) of the second drainage pipe 34 is a channel perpendicular to the first end (vertical section) that passes through the outlet protrusion 32 and its adjacent side end. A second sealing plug 37 is provided on the adjacent side end of the outlet protrusion 32 to prevent water from flowing out from that side. Figure 6 As shown, the sealing assembly 3 is made of elastic material. To create channels perpendicular to the first (vertical) ends of the first drain pipe 33 and the second (horizontal) ends of the second drain pipe 34, the simplest method is to directly open the second ends of the first drain pipe 33 and the second drain pipe 34 into channels penetrating one side wall during the plastic molding of the sealing assembly 3. Seal the passages where water flow is not required by adding water-sealing plugs. This reduces the difficulty of machining the three-dimensional channel inside the sealing assembly 3. On the other hand, after sealing the second ends of the first drain pipe 33 and the second drain pipe 34 using the first water-sealing plug 36 and the second water-sealing plug 37, the sealing assembly 3 is inserted into the pump housing 2, as shown... Figure 6 As shown, the outer wall of the water pump housing 2 can further support the first sealing plug 36 and the second sealing plug 37 to prevent leakage of the first sealing plug 36 and the second sealing plug 37 under a certain water flow pressure.

[0058] In one or more alternative embodiments, such as Figure 5 , Figure 7 , Figure 9 , Figure 11As shown, the mounting housing 2 has a partition 21 near its small opening end. This partition 21 separates the mounting housing 2 into a mounting cavity (not shown in the attached figure) for assembling the water pump 1 and a wiring cavity M for wiring the pump 1. The mounting housing 2 has an opening at its large end, which contains a mounting cavity for assembling the water pump 1. The water pump 1 is cylindrical, and the mounting cavity is also cylindrical. When the water pump 1 is assembled in the mounting cavity, the outer side of the water pump 1 abuts against the cavity wall, thus ensuring stable assembly and preventing the water pump 1 from shaking in the mounting cavity when the mounting housing 2 collides with other structures. Additionally, the mounting housing 2 has a large end and a small end positioned opposite each other. The mounting housing 2 has open ends at both the large and small ends. Near the small end, the mounting housing 2 has a partition 21, which isolates a wiring cavity M above the mounting cavity. The partition 21 has two outlet holes (not shown in the attached diagram) corresponding to the two electrode plates (not shown in the attached diagram) of the water pump 1. The electrode leads of the water pump 1 can pass through the outlet holes into the wiring cavity M and then be welded to two power outlet sockets / pins a1 and a2 at the end of the wiring cavity for external power access. One side of the sealing assembly 3 has an inlet 31 and an outlet 32 ​​that communicate with the water inlet 11 and outlet 12 of the water pump 1, respectively. That is, the water inlet 11 of the water pump 1 is connected to the inlet 31, and the water outlet 12 of the water pump 1 is connected to the outlet 32. When water is injected from the outside, water is injected into the water inlet 11 of the water pump 1 through the water inlet 31; conversely, when water is injected from the outside, water is injected into the water outlet 12 of the water pump 1. During this process, water is prevented from leaking into the interior of the floor scrubber because the sealing component 3 is sealed to the large end opening of the mounting housing 2.

[0059] In this embodiment, as Figures 5 to 7 , Figures 9 to 10As shown, a recessed platform 35 is provided on the end face of the sealing component 3 connected to the water pump 1. When replacing the water pump 1 inside the mounting housing 2, first remove the sealing component 3 from the large end of the mounting housing 2. At this time, the opening of the large end of the mounting housing 2 has been opened. Then, detach the water pump 1 from the mounting housing 2 in the direction away from the small end of the mounting housing 2, and the entire water pump 1 can be removed. Simply put, after removing the sealing component 3 from the large end opening of the mounting housing 2, rotate the water pump component 100 so that the large end opening of the mounting housing 2 faces the direction of gravity. Under the action of gravity, the water pump 1 can slowly slide out of the large end opening of the mounting housing 2. When assembling the water pump 1 into the mounting cavity, first pass the two electrode leads of the water pump 1 through the two outlet holes of the partition 21. Then, with the large end opening of the mounting housing 2 facing upwards and the two electrical terminals of the water pump 1 facing downwards, slide the water pump 1 into the mounting housing 2 until the electrical terminals of the water pump 1 abut against the partition 21. At this point, continue to press the sealing assembly 3 into the first end (vertical section) of the first drain pipe 33 and the first end (vertical section) of the second drain pipe 34 of the sealing assembly 3, with the concave platform 35 facing the water pump 1's inlet 11 and outlet 12, until the water pump 1 is close to the concave platform 35 of the sealing assembly 3, connecting the water pump 1's inlet 11 with the inlet 31 and the water pump 1's outlet 12 with the outlet 32. Only then is the alignment and connection of the water pump 1's inlet and outlet ends with the sealing assembly 3 completed. Finally, after the connection is completed, the exposed end face of the sealing assembly 3 and the large end face of the mounting housing 2 should be kept flush. In addition, the outer diameter of the recess 35 is the same as the outer diameter of the water pump 1. Therefore, after the recess 35 of the water pump 1 is aligned and connected with the sealing component 3, the stability of the water pump 1 is further improved.

[0060] In this embodiment, as Figure 1 , Figure 5 , Figure 6 , Figure 7As shown, the sealing assembly 3 is provided with a first drainage pipe 33 and a second drainage pipe 34. When water passes through the sealing assembly 3, it is either poured into the water pump 1 or flows out of the water pump 1 through the first drainage pipe 33 and the second drainage pipe 34. The first end (vertical section) of the first drainage pipe 33 is connected to the water inlet 11 of the water pump 1, and the second end (horizontal section) of the first drainage pipe 33 is connected to the water inlet 31. Both the first end (vertical section) and the second end (horizontal section) of the first drainage pipe 33 are open. When the water inlet 11 of the water pump 1 passes through the first end (vertical section) of the first drainage pipe 33 and the water supply tank of the floor scrubber passes through the water inlet 31 of the second end (horizontal section) of the first drainage pipe 33, a water inlet pipeline is formed. At this time, the water supply tank of the floor scrubber pours water into the water pump 1. The first end (vertical section) of the second drainage pipe 34 is connected to the outlet 12 of the water pump 1, and the second end (horizontal section) of the second drainage pipe 34 is connected to the outlet 32. Both the first end (vertical section) and the second end (horizontal section) of the second drainage pipe 34 are open. When the outlet 12 of the water pump 1 passes through the first end (vertical section) of the second drainage pipe 34 and the water tank of the floor scrubber passes through the outlet 32 ​​of the second end (horizontal section) of the second drainage pipe 34, a water outlet pipeline is formed. At this time, water flows from the water pump 1 into the outlet pump 1. Through the first drainage pipe 33 and the second drainage pipe 34, the water does not interfere with each other during the process of entering or leaving the water pump 1. The sealing assembly 3, which incorporates a first drain pipe 33 and a second drain pipe 34, simplifies the water pipe connection process, which previously required two pipes to connect to and from the water pump 1 and then to the target interface. Only the axial alignment of the water pump relative to the recess 35 of the sealing assembly 3 is needed to connect the water pump 1's inlet 11, outlet 12, and sealing element 3. Connecting the first drain pipe 33 and the second drain pipe 34 on the sealing assembly 3 to the water inlet B1 and outlet B2 of the floor scrubber body simultaneously completes the connection of the four pipe interfaces of the water pump assembly 100 into the floor scrubber body 200. In short, by adopting the water pump assembly 100 of this application, only two directional connection actions are needed to achieve the goal of connecting four pipe interfaces required in the prior art, thus improving the manufacturing efficiency of the floor scrubber. Users can also improve the efficiency and convenience of water pump maintenance when encountering pump failures and need to replace or maintain the pump.

[0061] It should be noted that the aforementioned water inlet B1, water outlet B2, water inlet 11, water outlet 12, positive electrode A1, and negative electrode A2 are merely alternative descriptions for the convenience of describing the technical solution. In actual application of the overall technical solution of this application, the water inlet, water outlet, water supply, water pumping, positive electrode, and negative electrode can be flexibly selected according to actual needs, and these technical solutions are all within the protection scope of this application.

[0062] In one or more alternative embodiments, such as Figure 5 , Figure 7 , Figure 9 , Figure 11 As shown, the mounting housing 2 has a partition 21 near the small end, and a wiring cavity M is separated above the mounting cavity. The wiring cavity M is provided inside the opening of the small end of the mounting housing 2 for mounting the end cover 4. Since the shape of the wiring cavity M matches the shape of the end cover 4, the outer side of the end cover 4 abuts against the groove wall of the wiring cavity M, so that the end cover 4 is completely accommodated in the wiring cavity M. In addition, the distance from the small end of the mounting housing 2 to the partition 21, i.e. the depth of the wiring cavity M, is consistent with the overall thickness of the end cover 4, so that the end cover 4 accommodated in the wiring cavity M is flush with the small end of the mounting housing 2 and cannot protrude outside the wiring cavity M, thereby reducing the height dimension occupied by the entire water pump assembly 100 in the space inside the floor scrubber body 200 and improving the internal utilization rate of the floor scrubber. Furthermore, on the side of the end cover 4 facing the wiring cavity M, there is an electrode partition 45 extending between the two power sockets / pins a1 and a2 inside the wiring cavity. The electrode partition extends from the end face of the end cover 4 that is flush with the end face of the power sockets / pins a1 and a2 of the water pump assembly 100 to the end of the length of the power sockets / pins a1 and a2 inside the wiring cavity M. In this way, the electrode partition 45 can prevent a small amount of water from leaking into the wiring cavity M, and the electrode partition 45 can still effectively prevent water from causing a short circuit between the two power sockets / pins a1 and a2 of the water pump assembly.

[0063] In one or more alternative embodiments, such as Figure 5 , Figure 9As shown, a first connecting post 22 is provided on the partition 21 of the wiring cavity M in the direction facing the end cover 4. The height of the first connecting post 22 is lower than the depth of the wiring cavity M. The height difference between the height of the first connecting post 22 and the depth of the wiring cavity M is exactly the wall thickness of the top of the end cover 4. Therefore, the first connecting post 22 is completely located in the wiring cavity M. When the end cover 4 is attached to the wiring cavity M, the end face of the end cover 4 is flush with the second end of the mounting housing 2. A threaded hole is provided at the end of the first connecting post 22 facing the end cover 4. The end cover 4 is provided with a through hole 42 corresponding to the first connecting post 22. For example, the first connecting post 22 is located in the central axis of the wiring cavity M, and the through hole 42 is located in the central axis of the end cover 4. When the end cover 4 is assembled in the wiring cavity M, the threaded hole and the through hole 42 are correspondingly arranged. The locking member 43 is simultaneously inserted into the through hole 42 and the threaded hole. Since the through hole 42 penetrates the wall thickness of the top of the end cover 4, the locking member 43 is threaded into the threaded hole after being inserted into the through hole 42, so as to assemble the end cover 4 into the wiring cavity M. When it is necessary to remove the water pump 1 from the mounting housing 2 for re-welding the power socket / pins a1 and a2, twist the locking member 43 until it disengages from the through hole 42 and the threaded hole. Then, remove the end cap 4 from the small end opening of the mounting housing 2. At this time, remove the sealing component 3 from the large end opening of the mounting housing 2. Rotate the water pump assembly so that the large end of the mounting housing 2 faces downwards, and the water pump 1 can slide out of the large end opening of the mounting housing 2 under gravity. After assembling the water pump 1 and completing the re-welding of the power socket / pins a1 and a2, assemble the end cap 4 into the wiring cavity M. The locking member 43 passes through both the through hole 42 and the threaded hole to stably assemble the mounting housing 2 between the end cap 4 and the sealing component 3, thereby improving the stability of the mounting housing 2. It should be noted that the locking member 43 in this embodiment of the invention is, for example, a screw or bolt, and is not specifically limited.

[0064] In one or more alternative embodiments, such as Figure 3 As shown, the inner side of the small end opening of the mounting housing 2 is also provided with a positioning groove (not shown in the attached figure) that communicates with the wiring cavity M. The outer periphery of the end cover 4 is provided with a positioning part 44. The groove shape of the positioning groove is adapted to the shape of the positioning part 44. For example, the shape of the end cover 4 is square, and the groove shape of the positioning groove is square. When the end cover 4 is assembled into the wiring cavity M, the outer side of the positioning part 44 abuts against the groove wall of the positioning groove to prevent the entire end cover 4 from rotating around the first connecting post 22, thereby further improving the stability of the end cover 4.

[0065] In one or more alternative embodiments, such as Figure 5 , Figures 7 to 9As shown, the water pump assembly 100 also includes a sealing end cap 5, which is sleeved on the electrode lead end of the water pump 1. Two lead-out guards 51, corresponding to the electrode lead of the water pump 1, are provided on the end face of the sealing end cap 5. Each lead-out guard 51 has a lead-out hole at its center. After the sealing end cap 5 is sleeved on the electrode lead end of the water pump 1, it is then inserted into the mounting housing 2. The sealing end cap 5 is elastically abutted against the partition 21 near the smaller end of the mounting housing 2. The lead-out guards 51 of the sealing end cap 5 correspond to the lead-out holes on the partition 21. The entire sealing end cap 5 is made of flexible material. Because water inside the water pump 1 is prone to leaking outside the mounting housing 2, this flexible sealing end cap 5 is provided at the end of the water pump 1 closest to the end cap 4. Combined with the flexible sealing assembly 3, which provides sealing protection for the water pump 1 at the first end of the mounting housing 2, the overall sealing performance of the water pump assembly can be further improved from both the larger and smaller ends of the mounting housing 2.

[0066] In one or more alternative embodiments, such as Figure 5 , Figure 7 , Figure 9 As shown, a positioning protrusion 13 is provided at one end of the water pump 1 near the end cover 4, and a second connecting post (not shown in the attached figure) is provided on the side of the sealing end cover 5 facing the positioning protrusion 13. The second connecting post is provided with a positioning groove (not shown in the attached figure). When the sealing end cover 5 is fitted onto the end of the water pump 1 near the end cover 4, since the outer diameter of the positioning groove is compatible with the outer diameter of the positioning protrusion 13, the positioning protrusion 13 can be inserted into the positioning groove, so that the sealing end cover 5 can be stably fitted onto the end of the water pump 1 near the end cover 4, avoiding the situation where the sealing end cover 5 shakes, and further improving the stability of the sealing end cover 5.

[0067] In one or more alternative embodiments, such as Figures 1 to 11 As shown, at least one fastening element 6 is provided on each opposite side of the mounting housing 2, for securing the entire water pump assembly 100 inside the floor scrubber body 200 and engaging it in the hook 201. Specifically, as... Figure 2As shown, at least one fastening member 6 extends outward from the small end of the mounting housing 2 along both opposite sides. The fastening member 6 first extends downward from the root of the small end of the mounting housing 2, and then turns back upward after reaching the lowest point, forming a V-shaped deformation portion 64 at the root of the small end of the mounting housing 2. From the lowest point of the turning point, the fastening member 6 extends upward at a certain angle, forming a snap-fit ​​sliding surface 63 on the surface of the fastening member 6. When the snap-fit ​​sliding surface 63 of the fastening member 6 continues to extend at a specific angle to near the mounting housing When the small end of body 2 is cylindrical and arc-shaped, when the two opposing fasteners 6 extend outward from the two sides of the snap-fit ​​sliding surface 63 in a direction that the two opposing fasteners 6 are further apart, the upper surface of the snap-fit ​​part 62 is provided with a snap-fit ​​platform (not shown in the figure) that cooperates with the lower surface of the hook 201 inside the body of the floor scrubber 200. The fasteners 6 continue to extend upward along a specific slope on the snap-fit ​​sliding surface 63 until a slightly outwardly curved pressing part 61 is formed at the end of the fasteners 6. When the user installs the water pump assembly 100 into the floor scrubber body 200, in addition to the water inlet and power outlet of the water pump assembly 100 cooperating with the components inside the floor scrubber body 200, the snap-fit ​​sliding surface 63 of the fastener 6 can continuously slide downward along the inner wall of the opposite hook 201. Under the combined action of the slope of the snap-fit ​​sliding surface 63 and the elastic stress of the V-shaped deformation part 64, when the water pump assembly 100 slides along the snap-fit ​​sliding surface 63 of the fastener 6 to a certain extent, the snap-fit ​​part 62 will spring towards the inner wall of the opposite hook 201 and form a stable elastic snap-fit ​​with the hook 201. When the user needs to remove the water pump assembly 100, they only need to press the pressing part 61 of the latching piece 6. This will cause the opposing locking parts 62 to retract towards each other and eventually disengage from the opposing hooks 201. The user can then simply lift the entire water pump assembly 100 upwards, away from the direction it slid into the locking mechanism, to separate the water pump assembly 100 from the floor scrubber body 200. Traditional water pump assemblies are generally directly fixed inside the floor scrubber body, requiring specialized tools for disassembly. However, in this embodiment of the invention, the water pump assembly can be removed simply by manually prying open the two latching pieces 6 on both sides of the mounting housing 2. This improves the ease of disassembly, truly achieving tool-free disassembly and assembly of the water pump assembly, and reducing the difficulty of maintenance for the user.

[0068] In one or more alternative embodiments, such as Figures 1 to 11As shown, the two power sockets / pins a1 and a2 of the mounting housing 2 and the two through holes 23 and 24 of the mounting housing 2 are on the same plane. Geometrically, the straight line formed by points a1 and a2 and the straight line formed by the centers of the two through holes 23 and 24 are parallel lines that must naturally lie on the same plane. The statement that the two power sockets / pins a1 and a2 of the mounting housing 2 and the two through holes 23 and 24 are on the same plane means that the side wall of the mounting housing 2, which includes the two power sockets / pins a1 and a2 and the two through holes 23 and 24, is itself a complete side wall on the same plane. This allows for convenient and quick installation of a flat mating side wall of the mounting housing 2 onto the corresponding flat inner side wall of the floor scrubber body 200. Furthermore, if the two power sockets / pins a1 and a2 of the mounting housing 2 and the two through holes 23 and 24 of the mounting housing 2 are respectively located on the stepped surfaces of the mounting housing 2 at two different heights, then the corresponding mating surface of the floor scrubber body 200 should also be a stepped surface, as long as the connection between the electrical interface and the water interface of the water pump assembly 100 can be achieved quickly in one go.

[0069] In this embodiment of the invention, the water pump assembly 100 allows for easy removal of the damaged water pump 1 from the mounting housing 2. This is achieved by disassembling the sealing component 3 from the large end opening of the mounting housing 2 and then removing the end cover 4 from the small end opening of the mounting housing 2. This disassembly process is convenient, reducing unnecessary disassembly steps for manufacturers and simplifying maintenance for users. Users can simultaneously disconnect and connect the electrical and water connections of the water pump assembly 100 when removing or installing it onto the floor scrubber body 200, improving maintenance efficiency. Using this water pump assembly, only two connection points on the same side in a single direction are required, achieving the goal of requiring four pipe interfaces in the prior art, thus improving the manufacturing efficiency of the floor scrubber. Furthermore, it improves the efficiency and convenience of water pump maintenance when users need to replace or maintain the water pump in case of failure.

[0070] Secondly, the present invention also provides a floor scrubbing machine, which is provided with the water pump assembly 100 provided in the first aspect. When replacing the water pump 1, the water pump assembly 100 in the floor scrubbing machine is disassembled and the water pump 1 located in the mounting housing 2 is taken out according to the aforementioned embodiment.

[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
