[0048] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0049] 1. By providing an open end at the bottom of the end plug body and using the abutting sealing cover to seal and abut against the end plug body at the open end, the abutting sealing cover and the end plug body jointly form two mutually sealed and isolated cavities (the water outlet transfer cavity and the water inlet transfer cavity). The spatial volume of the two mutually sealed and isolated cavities is also cleverly utilized, avoiding the need for a 3D three-dimensional spatial position connecting pipeline that should be provided inside the end plug body 30, and at the same time avoiding the technical problem that the end plug body simply cannot be processed by the thin-wall injection molding process. At the same time, the water outlet transfer cavity and the water inlet transfer cavity are embedded in the end plug body, reducing the solid volume of the end plug body, thereby reducing the raw materials required in the actual injection molding production process, further reducing the weight of the entire end plug body, and improving the production efficiency of manufacturing this component. Further, on the end plug body of the water pump end plug kit, by using the two independent closed cavity spaces built in it, the water inlet and outlet directions of the water inlet and outlet ends of the water pump are cleverly realized to turn vertically in the two cavities respectively and pass through two through holes provided on the side wall of the mounting housing, eliminating the need for the corresponding complex water pipeline connection that should be completed on the end plug body.

[0050] 2. Remove the water pump end plug kit from the large opening end of the installation housing, and then remove the end cover from the small opening end of the installation housing. After that, the damaged water pump located entirely within the installation housing can be taken out. This disassembly process is convenient and reduces the unnecessary disassembly procedures for the manufacturer.

[0051] 3. When the user installs or removes the water pump assembly from the floor washer body for the first time, the electrical connection and water connection of the water pump assembly can be disconnected or connected at one time, improving the maintenance efficiency.

[0052] 4. After adopting the water pump assembly of the present application, only two docking actions are required to achieve the goal that requires four pipeline interface docking actions in the prior art. The production and manufacturing efficiency of the floor washer can be improved. When the user needs to replace and maintain the water pump in case of a water pump failure, the replacement and maintenance efficiency can also be improved, enhancing the convenience of water pump maintenance.

[0070] The following further details the claims of the present utility model in conjunction with specific embodiments and the attached drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts also fall within the protection scope of the present utility model.

[0071] It should be understood that in the description of the embodiments of the present utility model, all terms indicating directional indications, such as "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship when the product of the present utility model is normally placed.

Unless otherwise clearly defined in the specification, when other understandings cannot achieve the corresponding functions or effects, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0074] As described in the background art section, in order to overcome the technical problem that in the technical solution of the existing floor washer, a professional disassembly tool is required to disassemble the housing of the water pump assembly, and the installation and maintenance efficiency of the water pump assembly by manufacturers and users is not high, the applicant filed a Chinese utility model patent application with the application number 202321262901.9 on May 19, 2023, disclosing a water pump end plug and a water pump assembly. The water pump end plug is used to seal a water pump with water inlet and outlet ends at the bottom in an installation housing with one end open to form a water pump assembly. The water pump end plug includes an end plug body, the end plug body has a mating end, a free end, and a circumferential surface connecting the mating end and the free end. The mating end is in sealing cooperation with the water inlet and outlet ends of the water pump, and turns the water inlet and outlet directions of the water inlet and outlet ends of the water pump perpendicular to pass through a first through hole 23 and a second through hole 24 on one circumferential side of the installation housing.

[0075] After continuous improvement and test verification by the inventor, it is found that on the one hand, due to the two drainage pipes sealed by means of two water sealing plugs in the end plug body of the water pump end plug, the 3D spatial pipelines of the two drainage pipelines in the end plug body are too complex, and in order to enclose the 3D spatial pipelines, the wall thickness of the injection molding of the end plug body in each area is uneven, resulting in low injection molding efficiency and large part deformation of a single end plug body, and low part qualification rate. Therefore, it is still necessary to further find a technical solution to optimize the end plug body and the entire water pump assembly.

[0076] To solve the technical problem that in the prior art, most water pump components are integrally arranged, making it difficult to take out the damaged water pump inside the water pump component, and most need to rely on professional disassembly tools to disassemble the outer shell of the water pump component, resulting in unnecessary disassembly processes for manufacturers. To further optimize the detachable water pump component and the design of the water pump end plug therein, the inventor made this application after further research and development, providing a water pump end plug kit and a water pump component. When the water pump is damaged, the water pump end plug kit is disassembled from the installation shell, and then the end cover is disassembled from the installation shell, and the entire water pump can be taken out. This disassembly process is convenient and reduces unnecessary disassembly processes for manufacturers. The following will be described in detail through specific embodiments.

[0077] Embodiment 1

[0078] Refer to Figures 1-6 , this embodiment provides a water pump end plug kit, which is used to seal the water pump 1 in an installation shell 2 with an opening at one end. The water pump end plug kit includes a water pump end plug 3 and a butt joint sealing cover 7.

[0079] Specifically, the water pump end plug 3 includes an end plug body 30. The end plug body 30 has a mating end (not marked in the figure), an open end (not marked in the figure), and a peripheral wall connecting the two. A cavity is enclosed inside the end plug body 30 by the mating end and the peripheral wall, and a partition wall 35 is provided from the mating end to the open end, dividing the cavity into an inlet transfer cavity N and an outlet transfer cavity M. The mating end is in sealing cooperation with the inlet and outlet ends of the water pump 1. An inlet part 11 and an outlet part 12 are provided at the bottom end of the water pump 1. The inlet part 11 is provided with an inlet channel leading into the water pump 1, and the outlet part 12 is provided with an outlet channel leading out of the water pump 1. The mating end is sealingly sleeved on the inlet part 11 and the outlet part 12 of the water pump 1. The outlet transfer cavity N and the inlet transfer cavity M are respectively communicated with the outlet part 12 and the inlet part 11 of the water pump 1. Among them, both the outlet part 12 and the inlet part 11 are provided at the outlet end of the water pump, and water outlet holes (not marked in the figure) and water inlet holes (not marked in the figure) are respectively provided on the side wall of the end plug body 30 corresponding to the outlet transfer cavity N and the inlet transfer cavity M. The butt joint sealing cover 7 abuts against the open end of the end plug body 30 and jointly forms the mutually sealed and isolated inlet transfer cavity N and outlet transfer cavity M with it. At the same time, the butt joint sealing cover 7 is detachably connected to the installation shell 2.

[0080] In a specific embodiment, refer to Figure 1 , Figure 5 and Figure 6, the abutting sealing cover 7 extends vertically with an inlet transfer cavity abutting enclosure wall 7n and an outlet transfer cavity abutting enclosure wall 7m towards the inlet transfer cavity N and the outlet transfer cavity M respectively, and is hermetically abutted against the inner walls of the inlet transfer cavity N and the outlet transfer cavity M respectively. This facilitates the demolding of the end plug body 30 by directly adopting the upper and lower mold splitting method during the production and manufacturing process, and the inlet transfer cavity N and the outlet transfer cavity M are arranged inside the end plug body 30, making full use of the space of the end plug body 30, being applicable to the manufacturing method of thin-wall injection molding, and the production is more efficient. By cleverly designing the inlet transfer cavity N and the outlet transfer cavity M, it avoids the problem of setting 3D communication pipelines inside the end plug body 30 in the prior art, and avoids the technical problem that the end plug body 30 cannot be manufactured by the thin-wall injection molding method, which affects the production and manufacturing efficiency.

[0081] On the other hand, the inventor found that the overall solid volume of the end plug body in the prior art is too large, resulting in a heavier weight of a single part, more injection molding materials required during the manufacturing process, and a higher cost of a single part. In this embodiment, since the inlet transfer cavity N and the outlet transfer cavity M occupy most of the solid volume of the end plug body 30, its solid volume is reduced, further reducing the raw materials required during the production and manufacturing process of injection molding, further reducing the weight of the entire end plug body 30, improving the production and manufacturing efficiency, and also reducing the production cost.

[0082] In a specific embodiment, refer to Figure 1 , Figure 5 and Figure 6 , the mating end of the end plug body 30 is provided with an abutting platform (not marked in the figure) that elastically seals and abuts against the inlet and outlet ends of the water pump 1. An inlet part interface 33 and an outlet part interface 34 are arranged on the abutting platform. The inlet part interface 33 and the outlet part interface 34 are respectively communicated with the inlet transfer cavity M and the outlet transfer cavity N, and the inlet part interface 33 and the outlet part interface 34 can be hermetically abutted against the inlet part 11 and the outlet part 12 respectively.

[0083] In a specific embodiment, refer to Figure 1 and Figure 6 , in the area near the abutting platform of the end plug body 30, a part of the side wall of the end plug body 30 is concave to form a weight reduction area (not marked in the figure), that is, the hollow area shown in the figure. The side wall of the weight reduction area is parallel to the side wall of the end plug body 30. The water inlet hole and the water outlet hole are arranged on the side wall of the weight reduction area. By setting this weight reduction area, the purpose of reducing the weight of the entire end plug body 30 is achieved, and the raw materials required for manufacturing the end plug body 30 are reduced. At the same time, since the side wall of the weight reduction area is parallel to the side wall of the end plug body 30, when the end plug body 30 is subsequently installed into the installation shell 2, it is beneficial to increase the sealing effect on the water pump 1 and can avoid water leakage from the gap between the end plug body 30 and the installation shell 2.

[0084] In a specific embodiment, refer to Figure 1 and Figure 6 , the water pump end plug 3 further includes a water inlet boss 31 and a water outlet boss 32, which are respectively in elastic sealing contact with the water inlet hole and the water outlet hole, and are both fixedly connected to the side wall of the weight reduction area. In order to achieve elastic sealing contact between the end plug body 30 and the installation housing 2, in this weight reduction area, at least one reinforcing rib (not marked in the figure) is fixedly connected to the outer side walls of the water inlet boss 31 and the water outlet boss 32, which can enhance the connection reliability between the water inlet boss 31 and the water outlet boss 32 and the weight reduction area.

[0085] In a specific embodiment, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 , the end plug body 30 is made of an elastic material. When the water inlet part interface 33, the water outlet part interface 34, the water inlet boss 31, and the water outlet boss 32 of the end plug body 30 are respectively docked with the water inlet part 11, the water outlet part 12 of the water pump 1 and the water supply port (not shown in the figure) and the water pumping port (not shown in the figure) of the floor washer body, the elastic deformation of the end plug body 30 itself can be used to eliminate the gaps between the hard water inlet part 11, the water outlet part 12 of the water pump 1 and the water supply port and the water pumping port of the floor washer body. Coupled with the subsequent installation of the end plug body 2 in the installation housing 2, the outer wall of the installation housing 2 can further support the outer peripheral wall of the end plug body 30 to prevent leakage at the various external interfaces of the end plug body 30 under a certain water flow pressure.

[0086] Embodiment 2

[0087] Based on the same inventive concept, the inventor proposes a water pump assembly 100. Refer to Figures 2-6 , the water pump assembly 100 includes a water pump 1, an installation housing 2 for accommodating the water pump 1, and the water pump end plug kit of Embodiment 1. Specifically, the water pump end plug kit includes a water pump end plug 3 and a contact sealing cover 7. The water pump end plug 3 includes an end plug body 30. The end plug body 30 is arranged in the installation housing 2, and one end thereof is in sealing contact with the water pump 1, and the contact sealing cover 7 is in sealing contact with the other end of the end plug body 30.

[0088] The installation housing 2 includes at least one open end (not marked in the figure) to facilitate the installation and removal of the abutting sealing cover 7, and the abutting sealing cover 7 is detachably connected to the installation housing 2. For the convenience of distinction, in the following description, the open end connected to the abutting sealing cover 7 is simply referred to as the large end. At the same time, an installation cavity (not marked in the figure) for assembling the water pump 1 is provided in the installation housing 2. The shape of the water pump 1 can be cylindrical as shown in the figure. Correspondingly, the installation cavity is cylindrical. When the water pump 1 is assembled in the installation cavity, the outer side of the water pump 1 abuts against the inner wall of the installation cavity, so as to be stably assembled in the installation cavity and prevent the water pump 1 from shaking in the installation cavity when the installation housing 2 collides with other devices.

[0089] During use, the water pump end plug 3 seals the water pump 1 in the installation housing 2 and can be detachably plugged into the large end of the installation housing 2. The water inlet and outlet directions of the water inlet and outlet ends of the water pump 1 are vertically turned and then pass through the first through hole 23 and the second through hole 24 on one side of the installation housing 2. When disassembling the installation housing 2, the water pump end plug 3 is disassembled from the large end of the installation housing 2. When assembling the installation housing 2, the water pump end plug 3 is directly elastically pressed into the assembly after facing the large end. When the water pump 1 in the installation housing 2 needs to be replaced due to damage, the user only needs to remove the water pump end plug 3 from the large end, and then rotate the water pump assembly 100 at this time so that the large end of the installation housing 2 faces the direction of gravity. Under the action of gravity, the water pump 1 can slowly slide out of the installation housing 2 by itself. After replacing the water pump 1 in the installation housing 2, the water pump end plug 3 is reassembled into the installation housing 2 from the large end again. The process of replacing the water pump 1 as a whole is very convenient.

[0090] In this embodiment, refer to Figure 1 、 Figures 3-6Referring to Example 1, an inlet port 33 and an outlet port 34 are provided within the water pump end plug 3. When water passes through the water pump end plug 3, it flows into the water pump 1 or out of the water pump 1 through the inlet port 33 and the outlet port 34. The inlet port 33 communicates with the water inlet 11 of the water pump 1, which in turn communicates with the water inlet hole via the water inlet adapter cavity N. The water inlet 11, the inlet connector 33, the water inlet adapter cavity N, the water inlet hole, and the water supply tank of the floor scrubber (not shown) are sequentially connected to form a water inlet pipeline. At this time, the water supply tank of the floor scrubber pours water into the water pump 1. The water outlet 12 of the water pump 1 communicates with the outlet port 34, which in turn communicates with the water outlet hole via the water outlet adapter cavity M, forming a water outlet pipeline. At this time, water flows out of the water pump 1 from the water pump 1. Through the water inlet interface 33 and the water outlet interface 34 and the isolated water inlet adapter chamber N and the water outlet adapter chamber M, water does not affect each other during the process of being poured into or out of the water pump 1. The water pump end plug 3 with the built-in water inlet interface 33 and the water outlet interface 34 makes the water pipe connection that originally required two pipes to connect to the water pump 1 and then to the target interface much simpler. It only requires the water pump 1 to be docked in the axial direction of the abutment platform of the water pump end plug 3 to achieve the docking of the water inlet 11, the water outlet 12 of the water pump 1 and the water inlet interface 33 and the water outlet interface 34. At the same time, the water inlet hole and the water outlet hole are docked to the water supply port and the water suction port of the floor scrubber body, thus achieving the connection of the four pipe interfaces of the water pump assembly 100 installed in the floor scrubber body. Simply put, the water pump assembly 100 of this embodiment achieves the purpose of four pipe interface docking operations required by the prior art by only requiring two docking operations, thereby improving the manufacturing efficiency of floor scrubbers. This also improves the efficiency of water pump replacement and maintenance when users encounter water pump failures and need to replace or maintain the water pump, making water pump maintenance more convenient.

[0091] In one embodiment, see Figure 3 and Figure 4 The abutting sealing cover 7 is flush with the end surface of the mounting housing 2 to prevent instability and damage caused by uneven placement. The mounting housing 2 has a horizontal connecting portion 25 on the bottom edge that cooperates with the sealing cover 7 and can be used to screw in screws. The abutting sealing cover 7 has a threaded hole (not shown) corresponding to the connecting portion 25. The use of screw fastening here further increases the sealing strength between the abutting sealing cover 7 and the mounting housing 2, thereby further improving the reliability of the seal between the abutting sealing cover 7 and the water inlet and outlet transition chambers N and M of the end plug body 30.

[0092] In a specific embodiment, a first through hole 23 and a second through hole 24 are respectively provided on the installation housing 2 corresponding to the water inlet hole and the water outlet hole. In this embodiment, reference can be made to Embodiment 1, where a water inlet boss 31 and a water outlet boss 32 are correspondingly arranged at the water inlet hole and the water outlet hole, a weight reduction area is arranged on the side surface of the end plug body 30, a plurality of reinforcing ribs are arranged on the outer sides of the water inlet boss 31 and the water outlet boss 32, both the water inlet boss 31 and the water outlet boss 32 are higher than the reinforcing ribs, and the height difference between the water inlet boss 31 and the water outlet boss 32 and the reinforcing ribs is greater than or equal to the wall thickness of the first through hole 23 and the second through hole 24. In this way, it can be ensured that when the entire water pump assembly 100 is installed into the body of the floor washer, it can elastically abut more fully against the water supply port (not shown in the figure) and the water pumping port (not shown in the figure) of the floor washer body, ensuring that the water supply port and the water pumping port extend more fully into the water inlet boss 31 and the water outlet boss 32. At the same time, the water inlet boss 31 and the water outlet boss 32 can be set to be higher than the installation housing 2, and the elasticity of the water inlet boss 31 and the water outlet boss 32 themselves can be used to quickly extend and fill the gap between the installation housing 2 and the floor washer body.

[0093] In a specific embodiment, refer to Figure 6 , on the water pump 1, a wire end (not marked in the figure) is provided relative to the water inlet and outlet ends. Two power-taking electrodes (not marked in the figure) are provided on the wire end. A sealing cover 5 is covered above the wire end, which can be used to cover the wire end. Two wire outlet protecting platforms 51 corresponding to the two power-taking electrodes of the water pump 1 are opened on the end surface of the sealing end cover 5. The power-taking electrodes can be accommodated in the wire outlet protecting platforms 51, which plays a role in protecting the power-taking electrodes.

[0094] In a specific embodiment, a positioning groove or a positioning boss is provided at the middle position of the sealing cover 5, and a positioning boss or a positioning groove is correspondingly provided at the middle position of the wire end of the water pump 1. Refer to Figure 6 , an example is given where a positioning groove (not shown in the figure) is provided at the middle position of the sealing cover 5 and a positioning boss 13 is provided at the middle position of the wire end of the water pump 1. When the sealing cover 5 is covered on the wire end of the water pump 1, since the outer diameter of the positioning groove is adapted to the outer diameter of the positioning boss 13, the positioning boss 13 can be inserted into the positioning groove to stably sleeve the sealing cover 5 on the water pump 1, avoiding the situation where the sealing cover 5 shakes and causing damage to the power-taking electrodes, and further improving the stability of the sealing cover 5.

[0095] In a specific embodiment, refer to Figure 5 and Figure 6, an opening is provided at the port of the mounting housing 2 opposite to the abutting sealing cover 7 (for the convenience of distinction, it is simply referred to as the small port end in the following description). A wiring cavity P is formed between the small port end and the sealing cover 5, which is used to accommodate the electrode lead wires electrically connected to the two power-taking electrodes. A partition 21 is arranged in the wiring cavity P to isolate the sealing cover 5, so as to isolate the mounting cavity for assembling the water pump 1 and the wiring cavity P for connecting the electrode lead wires of the water pump 1, and protect the electrical safety. Two power-taking sockets or pins a1, a2 are provided on the side wall of the wiring cavity P, and their orientations are the same as those of the first through hole 23 and the second through hole 24. The partition 21 is provided with wire outlet holes corresponding to the two power-taking electrodes (not shown in the figure). The electrode lead wires can pass through the wire outlet holes and enter the wiring cavity P, and are electrically connected to the power-taking sockets / pins a1, a2 to supply power to the water pump 1. At the same time, the positive electrode and the negative electrode of the electrode matching with the power-taking sockets / pins a1, a2 can be arranged on the body of the floor washer. When the user disassembles or installs the water pump assembly 100 on the body of the floor washer once, the electrical connection and the waterway connection of the water pump assembly 100 can be disconnected or connected at one time, improving the maintenance efficiency.

[0096] During use, when assembling the water pump 1 in the mounting cavity, first pass the two electrode lead wires of the water pump 1 through the two wire outlet holes of the partition 21, then place the large port end opening of the mounting housing 2 upward and the wire end of the water pump 1 downward, and slide the water pump 1 into the mounting housing 2 smoothly until the electrode end of the water pump 1 abuts against the partition 21. At this time, continue to press the abutting platform of the water pump end plug 3 against the water inlet part 11 and the water outlet part 12 of the water pump 1 until the water pump 1 abuts against the abutting platform of the water pump end plug 3, further improving the stability of the water pump 1 and making the water inlet part interface 33 and the water outlet part interface 34 respectively connected to the water inlet part 11 and the water inlet 31. In this way, the alignment connection between the water inlet and outlet ends of the water pump 1 and the water pump end plug 3 is completed. After the connection is completed, the exposed end face of the water pump end plug 3 and the end face of the large port end of the mounting housing 2 are kept flush.

[0097] In a specific embodiment, refer to Figure 6, The two power-taking sockets / pins a1, a2 of the mounting housing 2 are in the same plane as the first through-hole 23 and the second through-hole 24 of the mounting housing 2. Of course, from a geometric perspective, a straight line formed by two points of the power-taking sockets / pins a1, a2, and another straight line formed by the centers of the first through-hole 23 and the second through-hole 24, these two parallel lines will surely be in one plane. When it is said that the two power-taking sockets / pins a1, a2 of the mounting housing 2 are in the same plane as the first through-hole 23 and the second through-hole 24 of the mounting housing 2, it means that the power-taking sockets / pins a1, a2, as well as the first through-hole 23 and the second through-hole 24, are simultaneously arranged on the side wall of the mounting housing 2. In this way, the side wall of a flat mounting housing 2 can be quickly and conveniently installed onto the corresponding flat inner side wall of the floor washer body. Further, if the power-taking sockets / pins a1, a2 and the first through-hole 23 and the second through-hole 24 are respectively arranged on the stepped surfaces of the mounting housing 2 at two different heights, then the corresponding docking surface of the floor washer body should also be a stepped surface, as long as the electrical interface and the waterway interface of the water pump assembly 100 can be quickly connected in one go.

[0098] In a specific embodiment, referring to Figure 6 , the water pump assembly 100 further includes an end cap 4, and the end cap 4 is detachably connected to the wiring cavity P. Different from the traditional mounting housing 2, the end cap 4 of this embodiment can be detached from the small-mouth end of the mounting housing 2. When the manufacturer needs to replace the power-taking sockets / pins a1, a2 inside the end cap 4, after detaching the end cap 4 from the small-mouth end of the mounting housing 2, the damaged power-taking sockets / pins a1, a2 located inside the mounting housing 2 can be taken out.

[0099] In this embodiment, it should be noted that the aforesaid water supply port, water pumping port, water inlet part 11, water outlet part 12, positive electrode, and negative electrode are only alternative expressions for the convenience of expressing the technical solution. In fact, referring to the intake water, outlet water, water supply, water pumping, positive electrode, and negative electrode in the overall application of the technical solution of the present application, alternative selections can be made flexibly according to actual needs, and these technical solutions are all within the protection scope of the present application.

[0100] In a specific embodiment, the entire sealing cover 5 is made of a flexible material. Since the water inside the water pump 1 is likely to leak outside the mounting housing 2, a flexible sealing cover 5 is provided at one end of the water pump 1 close to the end cap 4. Cooperating with the flexible water pump end plug 3 to seal and protect the water pump 1 can further improve the overall sealing performance of the water pump assembly 100 from the two ends of the large-mouth end and the small-mouth end of the mounting housing 2.

[0101] In a specific embodiment, referring to Figure 5 and Figure 6, a connecting post 22 is provided in the wiring cavity P, and a through hole 42 corresponding to the connecting post 22 is provided on the end cover 4. The end cover 4 is detachably connected to the wiring cavity P through a locking member 43. Specifically, the locking member 43 passes through the through hole 42 and is detachably connected to the connecting post 22. The end cover 4 can be conveniently detached from the small-end, facilitating the replacement of the power-taking socket / plug pins a1 and a2.

[0102] In a specific embodiment, refer to Figure 2 and Figure 6 , at least one buckling member 6 is provided on both opposite sides of the mounting housing 2 for clamping the entire water pump assembly 100 inside the body of the floor washer (not shown in the figure). Specifically, refer to Figure 2 , at least one buckling member 6 extends outward along both opposite sides of the small-end of the mounting housing 2. The buckling member 6 first extends downward from the root of the small-end of the mounting housing 2. When it reaches the lowest point, it turns back and extends upward to form a V-shaped deformation part (not marked in the figure) at the root of the small-end of the mounting housing 2. The buckling member 6 extends upward along a certain slope from the lowest point of the turning-back point, forming a clamping sliding-in surface (not marked in the figure) on the surface of the buckling member 6. When the clamping sliding-in surface of the buckling member 6 continues to extend along a specific slope to approach the columnar arc top of the small-end of the mounting housing 2, two opposite buckling members 6 extend outward with clamping parts (not marked in the figure) on both sides of the clamping sliding-in surface in the direction away from the two opposite buckling members 6. The upper surface of the clamping part is provided with a clamping and abutting platform (not marked in the figure) that cooperates with the lower surface of the hook inside the body of the floor washer. The buckling member 6 continues to extend upward along a specific slope on the clamping sliding-in surface until a slightly outwardly bent pressing part (not marked in the figure) is formed at the end of the buckling member 6.

[0103] When the user installs the water pump assembly 100 into the body of the floor scrubber, in addition to the aforementioned water pipe interface and power interface of the water pump assembly 100 cooperating with the components inside the floor scrubber, the snap-in surface of the buckle 6 can continue to slide downward along the inner wall of the relative hook. Under the combined effect of the inclination of the snap-in surface and the elastic stress of the V-shaped deformation portion, when the water pump assembly 100 slides to a certain extent along the snap-in surface of the buckle 6, the snap-in portion will rebound toward the inner wall of the relative hook and form a stable elastic snap-in connection with it. When the user needs to remove the water pump assembly 100, he only needs to press the pressing portion of the buckle 6 first, so that the relative snap-in portions will shrink toward each other and eventually break away from the inner wall of the hook. At this time, the user only needs to remove the entire water pump assembly 100 upward away from the direction of the sliding snap-in connection to complete the separation of the water pump assembly 100 from the floor scrubber body. Traditional water pump assemblies 100 are typically fixed directly inside the body of the floor scrubber, requiring specialized disassembly tools to disassemble the water pump assembly. However, the water pump assembly 100 of this embodiment can be removed by manually prying open the buckles 6 on both sides of the mounting housing 2, allowing the entire water pump assembly 100 to be removed. This improves disassembly convenience, truly achieving tool-free disassembly and assembly of the water pump assembly 100 and reducing the difficulty for users to maintain the water pump assembly 100.

[0104] The water pump assembly 100 of this embodiment can remove the water pump end plug 3 from the large end of the mounting shell 2, and then remove the end cover 4 from the small end of the mounting shell 2, and then the damaged water pump 1 located in the mounting shell 2 can be taken out. This disassembly process is convenient, which reduces the manufacturer's unnecessary disassembly process and reduces the difficulty for users to maintain the water pump assembly 100. When the user removes or installs the water pump assembly 100 to the body of the floor scrubber at a single time, the electrical connection and water connection of the water pump assembly 100 can be disconnected or connected at one time, thereby improving the efficiency of maintenance. After adopting the water pump assembly of the present application, only two docking actions are required to achieve the goal that can only be achieved by docking actions of four pipe interfaces in the prior art, and the production and manufacturing efficiency of the floor scrubber can be improved. When the user needs to replace and maintain the water pump when encountering a water pump failure, the efficiency of replacement and maintenance can also be improved, thereby improving the convenience of water pump maintenance.

The description of the above embodiments is only intended to help understand the method and core ideas of the present application. At the same time, changes or modifications made by those skilled in the art based on the ideas of the present application, the specific implementation methods, and the scope of application of the present application, all fall within the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
