[0028] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0033] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] This disclosure provides a cleaning component and a cleaning device. The cleaning device includes a cleaning component, which can be various cleaning devices such as fabric cleaning machines, carpet cleaners, handheld floor scrubbers, and robot vacuum cleaners. This disclosure does not limit the scope of the cleaning device. The following description uses a fabric cleaning machine as an example, and the structure and working principle of the cleaning component will be described simultaneously with the description of the cleaning device. In embodiments where the cleaning device is a fabric cleaning machine, the cleaning component can be a cleaning brush head on the fabric cleaning machine.

[0036] Fabric cleaning machines are used to clean surfaces such as sofas, carpets, curtains, and leather chairs. After prolonged use, fabric items accumulate dirt on their surfaces, which the cleaning components of the fabric cleaning machine can remove. The working principle of a fabric cleaning machine is mainly based on a three-step process: spraying water to dissolve stains, brushing to loosen dirt, and using strong suction to remove dirty water. Therefore, the cleaning components must have at least the functions of spraying water and negative pressure suction.

[0037] The cleaning assembly disclosed herein includes a first housing, a cleaning component, and a water inlet component. The cleaning component is floatingly connected to the first housing and has a cleaning element for cleaning the work surface. Further, the cleaning assembly also includes a second housing, within which the cleaning component can be disposed, and a negative pressure suction port is formed between the first and second housings, surrounding the cleaning component. During cleaning operations, the cleaning component conforms to the work surface, and under negative pressure, wastewater generated during cleaning is drawn into the cleaning assembly through the negative pressure suction port. The cleaning component, floatingly connected to the first housing, can adaptively float up and down based on the actual condition of the work surface (e.g., according to the material, flatness, hardness, etc. of the work surface).

[0038] This disclosure provides a cleaning component that is floatingly connected to the first housing. This eliminates the need for the user to scrape water downwards during cleaning. Instead, the cleaning component automatically floats up and down due to changes in vacuum levels under different fabric conditions. This achieves automatic fabric cleaning and self-absorption, resulting in labor-saving cleaning and improved cleaning efficiency.

[0039] The cleaning component has at least a first water outlet channel and a second water outlet channel, which correspond to different water outlet modes. Specifically, the two water outlet modes can be a uniform water outlet mode and a high-pressure water spray mode, respectively. The water inlet component has a water inlet passage for supplying water to the cleaning component, wherein the cleaning component and the water inlet component are configured to switch between a first coupling state and a second coupling state. When the cleaning component and the water inlet component are in the first coupling state, the water inlet passage is connected to the first water outlet channel; when the cleaning component and the water inlet component are in the second coupling state, the water inlet passage is connected to the second water outlet channel.

[0040] This disclosure allows for switching between at least two water patterns through the relative movement of the cleaning component and the water inlet component: when switching to the uniform water output mode, it can clean surface dirt; when switching to the high-pressure water spray mode, it can achieve deep cleaning. This enhances the functionality of the cleaning component, thereby better meeting the user's cleaning needs.

[0041] Users can manually control the relative movement of the cleaning component and the water inlet component, or control them via electronic control, remote control, or other means. Specifically, the cleaning component can be set to remain stationary while the water inlet component is controlled to move, thereby switching between the two coupling states and thus switching between water type modes; alternatively, the water inlet component can be set to remain stationary while the cleaning component is controlled to move, thereby switching between the two coupling states and thus switching between water type modes.

[0042] This disclosure provides the following two specific embodiments: Embodiment 1 provides a specific scheme in which the cleaning component is fixed and the water inlet component moves; Embodiment 2 provides a specific scheme in which the water inlet component is fixed and the cleaning component moves. The two specific embodiments provided in this disclosure will now be described with reference to the accompanying drawings.

[0043] Example 1 refer to Figures 1 to 9 The cleaning assembly provided in this disclosure includes a first housing 1, a cleaning component floatingly connected to the first housing 1, and a water inlet component. For example... Figure 3 As shown, the first housing 1 is the outer shell of the cleaning component. The first housing 1 has a first inner cavity 10, in which the cleaning component and the water inlet component can be installed.

[0044] In one embodiment of this disclosure, the first housing 1 includes a main body and a connecting portion extending outward from the main body. Both the cleaning component and the water inlet component are installed in the first inner cavity 10 of the main body of the first housing 1. The connecting portion can be used to connect to the main unit of the cleaning equipment, or to connect to a pipeline for connection to the main unit. Specifically, the cleaning component is connected to the main unit of the cleaning equipment via both water and air.

[0045] refer to Figures 1 to 3 A decorative cover 12 can be provided on the connecting part, and a water inlet connector 13 is provided inside the decorative cover 12. The water inlet end of the water inlet connector 13 extends outward to the end of the decorative cover 12 to form a main water inlet 11. The main water inlet 11 can be used to connect with the main unit of the cleaning equipment to establish a water circuit, and the main unit can supply clean water or cleaning fluid to the water inlet connector 13 through the main water inlet 11. The water inlet component has a water inlet passage for supplying water to the cleaning component, and the water outlet end of the water inlet connector 13 extends inward and communicates with the water inlet passage. The cleaning fluid from the main unit of the cleaning equipment can be delivered to the cleaning component in sequence through the main water inlet 11, the water inlet connector 13, and the water inlet passage of the water inlet component, thereby enabling the cleaning component to achieve a water-based cleaning effect.

[0046] refer to Figures 1 to 3 The cleaning component includes a cleaning element 9 for cleaning the work surface, which may include cleaning components such as a brush head and a cloth head. In a specific embodiment of this disclosure, such as Figure 1 As shown, the cleaning component 9 is provided with a nozzle 96 for spraying liquid. The nozzle 96 can spray clean water or cleaning liquid onto the working surface and / or the cleaning component, thereby cleaning the working surface with water. The nozzle 96 may include a high-pressure water spray nozzle located at the center of the bottom surface of the cleaning component 9, and may also include multiple uniformly sprayed water nozzles arranged around the center.

[0047] refer to Figure 7The cleaning component 9 has at least a first water outlet channel 91 and a second water outlet channel 92, which correspond to different water outlet modes. Specifically, the water outlet mode corresponding to the first water outlet channel 91 can be a uniform water outlet mode, and the water outlet mode corresponding to the second water outlet channel 92 can be a high-pressure water spray mode. The cleaning component 9 may include a first top plate 901, a first bottom plate 902, and a middle plate 903 sandwiched between the first top plate 901 and the first bottom plate 902. A flow channel groove may be formed on the middle plate 903, and the first top plate 901 and the first bottom plate 902 can be enclosed with the flow channel groove to form the first water outlet channel 91 and the second water outlet channel 92.

[0048] In one specific embodiment of this disclosure, such as Figure 7 As shown, the first water outlet channel 91 includes a first inlet 911 formed on the first top plate 901 and a first outlet 912 formed on the first bottom plate 902. The first water outlet channel 91 can be constructed as an annular structure, and a plurality of first outlets 912 arranged around the center can be formed at the bottom of the first water outlet channel 91, and the first outlets 912 can communicate with a plurality of uniformly emitting water nozzles. Liquid from the first inlet 911 can flow along the annular first water outlet channel 91 and be uniformly distributed therein, thereby uniformly discharging water from the plurality of first outlets 912.

[0049] In one specific embodiment of this disclosure, such as Figure 7 As shown, the second water outlet channel 92 includes a second inlet 921 formed on the first top plate 901 and a second outlet 922 formed on the first bottom plate 902. The second outlet 922 is located at the center of the first bottom plate 902 and can communicate with a high-pressure water nozzle. Conversely, the second inlet 921 is located on the first top plate 901 away from the center. The second water outlet channel 92 can be constructed as a straight line, thereby connecting the second inlet 921 to the second outlet 922. Liquid from the second inlet 921 can flow along the straight second water outlet channel 92, thereby flowing rapidly to the second outlet 922 to achieve high-pressure water output.

[0050] The cleaning component includes a second housing 2 for mounting the cleaning element 9, such as Figure 3 As shown, the second housing 2 has a second inner cavity 20, and the cleaning component 9 is disposed in the second inner cavity 20. The second housing 2 is constructed to be nested within the first inner cavity 10, and a negative pressure suction port 15 surrounding the cleaning component 9 is formed between the first housing 1 and the second housing 2. Specifically, during operation, the cleaning component 9 can conform to the working surface, and under the action of negative pressure, the wastewater generated during cleaning is sucked up by the cleaning component through the negative pressure suction port 15. The cleaning component, which is floatingly connected to the first housing 1, can adaptively float up and down based on the actual condition of the working surface (e.g., according to the material, flatness, hardness, etc. of the working surface).

[0051] In one embodiment of this disclosure, the water inlet component is configured to drive the cleaning component to float relative to the first housing 1 in a predetermined direction. For example... Figure 3 As shown, the dashed line Z indicates the preset direction, which can be perpendicular to the cleaning component 9. The water inlet component can drive the cleaning component to float along the Z direction, thereby allowing the cleaning component 9 to adaptively float up and down. Specifically, the cleaning component is configured to be connected to the water inlet component. This disclosure allows the cleaning component to be installed on the water inlet component, thereby forming both a water circuit connection and a transmission relationship. (Reference) Figure 3 The water inlet component is configured to float on the first housing 1 via an elastic device 6. Under the action of the elastic device 6, the water inlet component floats on the first housing 1, thereby indirectly connecting the cleaning component to the first housing 1. Both components float up and down together in a preset direction. This disclosure, by providing a cleaning component that floats on the first housing 1, eliminates the need for the user to scrape water downwards during cleaning. Instead, the cleaning component 9 adaptively floats up and down based on changes in vacuum levels under different fabric conditions, achieving automatic fabric cleaning and self-absorption, thus saving effort and improving cleaning efficiency.

[0052] The cleaning component and the water inlet component can switch between a first coupling state and a second coupling state. When the cleaning component and the water inlet component are in the first coupling state, the water inlet passage is connected to the first water outlet channel 91; when the cleaning component and the water inlet component are in the second coupling state, the water inlet passage is connected to the second water outlet channel 92. Specifically, in this embodiment, the cleaning component can be fixed, and the user can control at least some components in the water inlet component to rotate relative to the cleaning component, thereby switching between two different coupling states and thus switching between two water pattern modes.

[0053] When the water inlet component is moved relative to the cleaning component to form a first coupling state, the water inlet passage can be connected to the first inlet 911. Liquid from the first inlet 911 can flow along the annular first outlet channel 91 and be evenly distributed therein, thereby uniformly discharging water from multiple first outlets 912. When switching to this uniform water discharge mode, surface dirt can be cleaned. When the water inlet component is moved relative to the cleaning component to form a second coupling state, the water inlet passage can be connected to the second inlet 921. Liquid from the second inlet 921 can flow along the linear second outlet channel 92, thereby quickly flowing to the second outlet 922, achieving high-pressure water discharge. When switching to this high-pressure water spray mode, deep cleaning can be achieved. This disclosure enhances the functional versatility of the cleaning component 9, thereby better meeting the user's cleaning needs.

[0054] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 5 and Figure 6 The water inlet component includes a switching lever 52 extending along a preset direction (i.e., the Z direction), and the switching lever 52 has a switching passage 520 forming at least part of the water inlet passage. The switching lever 52 is configured to move relative to the cleaning component, switching the water inlet component and the cleaning component between a first coupling state and a second coupling state. Specifically, when the cleaning component and the water inlet component are in the first coupling state, the switching lever 52 is located in a first working position relative to the cleaning component, and the switching passage 520 is connected to the first water outlet channel 91; when the cleaning component and the water inlet component are in the second coupling state, the switching lever 52 is located in a second working position relative to the cleaning component, and the switching passage 520 is connected to the second water outlet channel 92.

[0055] In one specific embodiment of this disclosure, the switching lever 52 is rotatable relative to the cleaning component about its axis, thereby switching between a first working position and a second working position. The switching passage 520 forms an inlet and an outlet 523 on the outer wall of the switching lever 52, wherein the outlet 523 is configured to communicate with either the first outlet channel 91 or the second outlet channel 92 during rotation. Optionally, the switching lever 52 may be provided with two inlets distributed circumferentially, such as... Figure 6 As shown, the two inlets are designated as the first inlet 521 and the second inlet 522, respectively. Correspondingly, the switching passage 520 within the switching rod 52 may also have two branches, one extending from the first inlet 521 to the outlet 523, and the other extending from the second inlet 522 to the outlet 523.

[0056] During the rotation of the switching lever 52, when switching to the first working position, the first water inlet 521 is connected to the water inlet connector 13, and the water outlet 523 is connected to the first water outlet channel 91. This allows the liquid from the water inlet connector 13 to flow through the water inlet passage between the first water inlet 521 and the water outlet 523 to the first water outlet channel 91, thus placing the water inlet component and the cleaning component in a first coupling state. When switching to the second working position, the second water inlet 522 is connected to the water inlet connector 13, and the water outlet 523 is connected to the second water outlet channel 92. This allows the liquid from the water inlet connector 13 to flow through the water inlet passage between the second water inlet 522 and the water outlet 523 to the second water outlet channel 92, thus placing the water inlet component and the cleaning component in a second coupling state.

[0057] In one embodiment of this disclosure, the water inlet component is provided with a mounting groove, and the switching rod 52 is configured to extend into the mounting groove and rotatably engage with it. Specifically, refer to... Figure 2 , Figure 4 and Figure 5The water inlet component includes a first water inlet bracket 3 and a first water outlet bracket 4. The mounting groove includes a first mounting groove 35 located on the first water inlet bracket 3 and a second mounting groove 41 located on the first water outlet bracket 4. The switching rod 52 passes through the first mounting groove 35 and the second mounting groove 41 from top to bottom, and is able to rotate relative to the first water inlet bracket 3 and the first water outlet bracket 4.

[0058] The water inlet component is provided with a first passage 31 that communicates with the water inlet and extends through the mounting groove. This first passage 31 can form at least a partial water inlet passage. Specifically, the first passage 31 is configured to penetrate the inner wall of the first mounting groove 35 and extend outward to a position corresponding to the water inlet connector 13. The first passage 31 provided on the first water inlet bracket 3 can be connected to the water inlet connector 13 through a pipe structure (e.g., a hose), and liquid from the water inlet connector 13 flows into the water inlet component through the first passage 31. The position of the switching rod 52 adjacent to its water inlet is configured to fit within the first mounting groove 35, and the water inlet of the switching rod 52 is configured to communicate with the first passage 31 during rotation. Optionally, the switching rod 52 can be rotated relative to the first water inlet bracket 3 to communicate with its first water inlet 521 and the first passage 31, or rotated to communicate with its second water inlet 522 and the first passage 31, thereby allowing liquid from the first passage 31 to flow into the switching passage 520. Optionally, a long strip-shaped water inlet extending circumferentially can be provided on the switching rod 52, so that the first passage 31 can always be connected to the switching passage 520 through the long strip-shaped water inlet during the rotation of the switching rod 52.

[0059] refer to Figure 4 The water inlet component is provided with a second passage 42 that communicates with the first water outlet channel 91 and passes through the mounting groove, and a third passage 43 that communicates with the second water outlet channel 92 and passes through the mounting groove. In the first coupling state, the second passage 42 constitutes at least a partial water inlet passage, and in this case, the water inlet passage, in the water flow direction, is sequentially the first passage 31, the switching passage 520, and the second passage 42. In the second coupling state, the third passage 43 constitutes at least a partial water inlet passage, and in this case, the water inlet passage, in the water flow direction, is sequentially the first passage 31, the switching passage 520, and the third passage 43.

[0060] Specifically, the second passage 42 and the third passage 43 are configured to penetrate the inner wall of the second mounting groove 41, respectively. The second passage 42, provided on the first water outlet bracket 4, can be connected to the first water outlet channel 91 via a pipe structure (e.g., a flexible hose), and the third passage 43, provided on the first water outlet bracket 4, can be connected to the second water outlet channel 92 via a pipe structure (e.g., a flexible hose). The first water outlet bracket 4 and the cleaning component 9 can be relatively fixedly installed together. In a specific embodiment of this disclosure, a mounting base 93 can be provided on the cleaning component 9, and the bottom of the first water outlet bracket 4 can sit in the mounting base 93, thereby fixing the two together.

[0061] The position of the switching rod 52 adjacent to its outlet 523 is configured to pass through the first mounting groove 35 and fit within the second mounting groove 41. The outlet 523 is configured to connect with the second passage 42 or the third passage 43 during rotation. Specifically, when the switching rod 52 rotates to the first working position, it rotates relative to the first water inlet bracket 3 to connect its first water inlet 521 with the first passage 31, and rotates relative to the first water outlet bracket 4 to connect its outlet 523 with the second passage 42, thereby opening the following passage: water inlet connector 13 → first passage 31 → switching passage 520 (first water inlet 521 → outlet 523) → second passage 42 → first water outlet channel 91. This achieves switching to a uniform water output mode, enabling the cleaning of surface dirt.

[0062] When the switching lever 52 rotates to the second working position, it rotates relative to the first water inlet bracket 3 so that its second water inlet 522 connects to the first passage 31, and rotates relative to the first water outlet bracket 4 so that its water outlet 523 connects to the third passage 43. This opens the following passage: water inlet connector 13 → first passage 31 → switching passage 520 (second water inlet 522 → water outlet 523) → third passage 43 → second water outlet channel 92. This enables deep cleaning when switching to the high-pressure water spray mode.

[0063] In one embodiment of this disclosure, reference is made to Figures 3 to 5 The switching lever 52 is configured to be supported on the first housing 1, and its end away from its outlet 523 is configured to extend through the first housing 1 to form an operating end 51. Two gaskets 526 are spaced apart along the axial direction on the switching lever 52, and the switching lever 52 is axially fixed to the first housing 1 by the gaskets 526. An operating end 51 exposed outside the first housing 1 is provided at the top of the switching lever 52. The operating end 51 can be a knob, so that the user can conveniently and intuitively control the rotation of the switching lever 52 by turning the operating end 51, thereby switching between the first working position and the second working position, and thus switching between different water output modes.

[0064] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 5 In the Z direction, that is, in the axial direction of the switching rod 52, the positions of the switching rod 52 on both sides of the water inlet are configured to seal with the inner wall of the first mounting groove 35 through the first sealing element 525. Two first sealing elements 525 can be arranged at intervals on the switching rod 52. The first sealing element 525 can be a sealing ring. Both first sealing elements 525 are tightly sealed with the inner wall of the first mounting groove 35 at their corresponding positions, thereby achieving a side seal with the first water inlet bracket 3. The side seal has the advantages of easy maintenance, good dynamic performance, and high durability. It is understood that during the process of rotating the switching rod 52 to switch the water path, the first water inlet 521 and the second water inlet 522 may not be aligned with the first passage 31, and the liquid from the first passage 31 may flow into the first mounting groove 35. In order to prevent further leakage of liquid during the water inlet process, this embodiment provides two first sealing elements 525 spaced apart in the axial direction, so that the water inlet is in the sealed space between the two first sealing elements 525, which achieves the effect of sealing and waterproofing.

[0065] In one embodiment of this disclosure, reference is made to Figure 5 A groove 5241 is provided on the side wall of the switching rod 52. A second sealing element 524 is provided in the groove 5241 for engaging with the inner wall of the second mounting groove 41. The outlet 523 of the water inlet passage is configured to extend to the end face of the second sealing element 524. The second sealing element 524 is configured to engage with the second passage 42 and the third passage 43 during rotation. Specifically, the second sealing element 524 can be a block-shaped sealing gasket, which is embedded in the groove 5241. An opening is made on the inner wall of the groove 5241 and extends through to the end face of the second sealing element 524, thereby forming the outlet 523. The second sealing element 524 is tightly sealed against the inner wall of the second mounting groove 41 at its corresponding position, thereby achieving a side seal with the first water outlet bracket 4. It is understandable that during the process of switching the water path by rotating the switching rod 52, the outlet 523 may not be aligned with the second passage 42 or the third passage 43, and the liquid from the water inlet passage may flow into the second mounting groove 41. In order to prevent the liquid from leaking out further during the water outflow process, this embodiment is provided with a second sealing member 524, thereby achieving the effect of sealing and waterproofing.

[0066] In one embodiment of this disclosure, a first water inlet bracket 3 is disposed on a first housing 1, and the first water inlet bracket 3 is configured to guide and engage with the first housing 1 along the Z direction (i.e., the axial direction of the switching rod 52). Specifically, as shown... Figure 9As shown, an inwardly protruding limiting protrusion 14 is provided on the inner wall of the first housing 1, and a first limiting groove 32 extending along the axial direction of the switching rod 52 is provided on the first water inlet bracket 3. The limiting protrusion 14 can extend into the first limiting groove 32. In this way, on the one hand, it restricts the rotational freedom of the first water inlet bracket 3 relative to the first housing 1, and on the other hand, it provides space for the first water inlet bracket 3 to float in the axial direction relative to the first housing 1.

[0067] Furthermore, an elastic device 6 is provided between the first water inlet bracket 3 and the first housing 1, and the first water inlet bracket 3 is configured to be floatingly connected to the first housing 1 via the elastic device 6. Figure 5 As shown, a first spring groove 33 is provided on the first water inlet bracket 3, and the first spring groove 33 can surround the outside of the first mounting groove 35. Figure 3 As shown, the elastic device 6 can be a spring, the lower end of which can extend into the first spring groove 33 and contact the bottom surface of the first spring groove 33; the upper end of the spring can be connected to the first housing 1.

[0068] The cleaning component can be installed below the first water inlet bracket 3, and thus floatably connected to the first housing 1 via the elastic device 6. Under the elastic force of the elastic device 6, the first water inlet bracket 3 can drive the cleaning component to float. During cleaning, the cleaning component can adaptively float up and down by changing the vacuum level under different fabric conditions, thereby achieving automatic fabric cleaning and self-absorption, realizing labor-saving cleaning and improving cleaning efficiency.

[0069] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 8 The second housing 2 is provided with a mating groove 23, and the first water outlet bracket 4 is configured to be located within the mating groove 23. The mating groove 23 is configured to be detachably connected to the first water inlet bracket 3. The second housing 2, the first water outlet bracket 4, and the cleaning component 9 together form a detachable assembly, and the first housing 1, the first water inlet bracket 3, and the switching rod 52 together form a fixed assembly. Users can easily remove the detachable components from the fixed assembly, thereby facilitating the replacement and cleaning of the cleaning component 9.

[0070] Specifically, a snap-fit ​​element 21 can be provided on the inner wall of the mating groove 23 of the second housing 2, and a snap-fit ​​groove 34 for engaging with the snap-fit ​​element 21 is provided on the outer wall of the first water inlet bracket 3. The snap-fit ​​element 21 extends into the snap-fit ​​groove 34 during external force screwing and is fixed. When disassembly is required, the user only needs to screw the cleaning component 9 or the second housing 2 in the opposite direction, thereby causing the snap-fit ​​element 21 to be withdrawn from the snap-fit ​​groove 34, thus easily achieving disassembly. In addition to using a snap-fit ​​method to achieve detachable connection, other detachable structures known to those skilled in the art, such as magnetic attraction, threads, and snap-fit, can also be used, and this disclosure does not limit this to any particular type.

[0071] Further, refer to Figure 4 and Figure 5 One end of the switching lever 52 near the outlet 523 is configured to detachably engage with the second mounting groove 41. The top of the second mounting groove 41 is an exposed opening. During installation, the user can insert the detachable assembly into the first inner cavity 10 of the first housing 1 and align the lower end of the switching lever 52 with the second mounting groove 41, allowing the lower end of the switching lever 52 to be inserted into the second mounting groove 41. With the snap-fit ​​21 and snap-fit ​​groove 34 in place, the outlet 523 of the switching lever 52 can communicate with the second passage 42 or the third passage 43. During disassembly, the user can unscrew the second housing 2 to unlock it, disengaging the snap-fit ​​21 from the snap-fit ​​groove 34, thereby allowing the detachable assembly to be removed as a whole, and the lower end of the switching lever 52 to be pulled out of the second mounting groove 41.

[0072] The above design solves the difficulty of combining floating design with detachability. Specifically, this disclosure incorporates a floating design for the fixed assembly. The first water inlet bracket 3 is floatingly connected to the first housing 1 via an elastic device 6, while the detachable assembly itself is not floating. The second housing 2 in the detachable assembly is snapped onto the first water inlet bracket 3, thus achieving both quick detachment and the ability for the cleaning component 9 to float up and down.

[0073] Furthermore, while the various structures of the detachable assembly are relatively fixed, the switching lever 52, used to switch water paths, is part of the fixed assembly. It can rotate relative to the first housing 1 and the first water inlet bracket 3 within the fixed assembly, thereby switching between different water inlet paths. In the installed state, the switching lever 52, extending into the second mounting groove 41, can rotate relative to the first water outlet bracket 4, allowing for the selection of the first water outlet channel 91 or the second water outlet channel 92 of the cleaning component 9 according to actual cleaning needs. This integrates quick-release, floating, and water path switching functions into the cleaning assembly.

[0074] Example 2 refer to Figures 10 to 18This embodiment also provides a cleaning component. The main difference between this embodiment and Embodiment 1 is that it provides a specific scheme in which the water inlet component is fixed and the cleaning component is movable. Based on this, the specific structures of the water inlet component and the cleaning component are significantly different in this embodiment, while the basic structure of the first housing 1 is basically the same as in Embodiment 1, and will not be described again in this embodiment.

[0075] refer to Figure 11 , Figure 17 and Figure 18 Similar to Embodiment 1, the cleaning component has a cleaning element 9 for cleaning the working surface, and the cleaning element 9 is provided with a nozzle 96 for spraying liquid. The cleaning element 9 has at least a first water outlet channel 91 and a second water outlet channel 92 corresponding to different water outlet modes. The cleaning element 9 may include a second top plate 904 and a second bottom plate 905. Specifically, flow path grooves may be formed on the second top plate 904 and the second bottom plate 905, and the second top plate 904 and the second bottom plate 905 can enclose the flow path grooves to form the first water outlet channel 91 and the second water outlet channel 92.

[0076] refer to Figures 11 to 13 The cleaning component includes a second housing 2 for mounting the cleaning element 9, and a water inlet component is disposed on the second housing 2. The cleaning element 9 rotates relative to the water inlet component to switch between a first coupling state and a second coupling state. When the cleaning element and the water inlet component are in the first coupling state, the cleaning element 9 is located in a third working position relative to the water inlet component, and the water inlet passage is connected to the first water outlet channel 91; when the cleaning element and the water inlet component are in the second coupling state, the cleaning element 9 is located in a fourth working position relative to the water inlet component, and the water inlet passage is connected to the second water outlet channel 92.

[0077] Specifically, refer to Figure 15 The cleaning component 9 is equipped with a switching handle 95, which can be hinged to the circumferential side wall of the cleaning component 9. The switching handle 95 can be constructed in a semi-circular shape. During cleaning operations, the switching handle 95 is rotated to a position flush with the cleaning component 9, thereby avoiding interference with the contact and fit between the bottom surface of the cleaning component 9 and the working surface. When it is necessary to switch water channels, the user can rotate the switching handle 95 to a position protruding from the bottom surface of the cleaning component 9 using the handle on the switching handle 95. This makes it easier for the user to hold the switching handle 95 and rotate the cleaning component 9. The cleaning component 9 can be rotated to the third or fourth working position, thereby achieving the switching to different water outlet modes.

[0078] Optionally, a switching lever can be provided on the cleaning component 9. The switching lever is connected to the cleaning component 9 and extends radially, passing through the side walls of the second housing 2 and the first housing 1 in sequence. This allows the switching lever to be at least partially exposed outside the first housing 1, making it convenient for the user to turn the cleaning component 9. Compared with the solution of providing a switching handle 95, this embodiment provides a more user-friendly switching method by providing a switching lever. Specifically, this embodiment avoids the need for the user to turn the cleaning component 9 over or reach to the bottom of the cleaning component 9 to pull the switching handle 95, thereby preventing the user's hands from touching dirt and improving the user experience.

[0079] In one embodiment of this disclosure, reference is made to Figures 13 to 15 The water inlet component includes a second water inlet bracket 7 and a second water outlet bracket 8. The second water inlet bracket 7 has a fourth passage forming at least a portion of the water inlet path, and the second water outlet bracket 8 has a fifth passage forming at least a portion of the water inlet path. The fifth passage is configured to communicate with the fourth passage, thereby forming a complete water inlet path. Specifically, refer to... Figure 11 and Figure 14 The internal cavity of the second water inlet bracket 7 is the fourth passage, and the second water inlet bracket 7 is provided with a liquid inlet connector 75 that communicates with the fourth passage. Specifically, the liquid inlet connector 75 can extend outward to the position corresponding to the water inlet connector 13, and is connected to the water inlet connector 13 through a pipeline structure (e.g., a hose). Liquid from the water inlet connector 13 flows into the second water inlet bracket 7 through the liquid inlet connector 75.

[0080] In one embodiment of this disclosure, such as Figure 11 and Figure 15 As shown, the second water outlet bracket 8 is provided with an extension 81 that extends into the fourth passage, and the fifth passage passes through the extension 81 and communicates with the water inlet passage. The cavity inside the extension 81 is the fifth passage, and the extension 81 extends into the cavity inside the second water inlet bracket 7, thereby connecting the fifth passage with the fourth passage. An opening for the extension 81 to extend into is provided at the bottom of the second water inlet bracket 7, and the fourth passage communicates with this opening. If it is not sealed, liquid will flow out from the bottom opening of the second water inlet bracket 7 during the water inlet process.

[0081] To allow liquid to flow smoothly from the fourth passage into the fifth passage, a third seal 82 is provided between the extension 81 and the fourth passage. (Refer to...) Figure 12 and Figure 13The third sealing element 82 can be a sealing ring fitted onto the upper part of the extension 81. When the extension 81 extends into the second water inlet bracket 7, the third sealing element 82 can tightly seal against the inner wall surface of the second water inlet bracket 7, thereby achieving a side seal between the extension 81 and the second water inlet bracket 7. The side seal has advantages such as easy maintenance, good dynamic performance, and high durability. In this embodiment, by providing the third sealing element 82, the fifth passage inlet at the top of the extension 81 is located in the sealed space above the third sealing element 82, thereby achieving a waterproof effect.

[0082] refer to Figure 15 and Figure 16 The fifth passage forms a water outlet 841 on the side of the second water outlet bracket 8 facing the cleaning component 9, for communicating with the first water outlet channel 91 or the second water outlet channel 92. This water outlet 841 is directly opposite the second top plate 904 of the cleaning component 9, on which a first inlet 911 and a second inlet 921 are spaced apart. Further, the cleaning component 9 is configured to be rotatably connected to the second water outlet bracket 8. When the cleaning component 9 rotates to the third working position, the first inlet 911 can rotate to communicate with the water outlet 841, thereby allowing the liquid flowing out of the water outlet 841 to flow into the first water outlet channel 91 through the first inlet 911; when the cleaning component 9 rotates to the fourth working position, the second inlet 921 can rotate to communicate with the water outlet 841, thereby allowing the liquid flowing out of the water outlet 841 to flow into the second water outlet channel 92 through the second inlet 921.

[0083] In one specific embodiment of this disclosure, reference is made to Figure 15 and Figure 16 The second water outlet bracket 8 has a notch 83 on the side facing the cleaning component 9. A fourth sealing element 84 for sealing with the cleaning component 9 is disposed within the notch 83. A fifth passage extends to form a water outlet hole 841 on the end face of the fourth sealing element 84. The fourth sealing element 84 can be a block-shaped sealing gasket embedded in the notch 83. A flow path for water outlet is provided inside the fourth sealing element 84. The fifth passage within the extension 81 connects to the notch 83. A mating interface 842 is provided on the end face of the fourth sealing element 84 facing the extension 81, and the mating interface 842 connects to the outlet of the fifth passage on the notch 83. The mating interface 842 connects to the water outlet hole 841 through the internal flow path of the fourth sealing element 84. Liquid from the fifth passage flows into the fourth sealing element 84 through the mating interface 842 and flows out from the water outlet hole 841, thus flowing to the first water outlet channel 91 or the second water outlet channel 92.

[0084] Understandably, during the rotation and water path switching process of the cleaning component 9, the first inlet 911 or the second inlet 921 may not be aligned with the water outlet 841, and liquid from the water outlet passage may flow into the gap between the second water outlet bracket 8 and the cleaning component 9. To prevent further leakage of liquid during the water outlet process, this embodiment provides a fourth sealing component 84, the bottom surface of which is in close contact with the end face of the cleaning component 9, thereby achieving a sealing and waterproofing effect.

[0085] In one embodiment of this disclosure, reference is made to Figure 15 Multiple mounting posts 94 protrude from the upper surface of the cleaning component 9, and correspondingly, multiple guide mounting grooves 85 are formed on the second water outlet bracket 8. The guide mounting grooves 85 can be constructed in an arc shape to accommodate the curvature of the cleaning component 9's rotation. The mounting posts 94 can pass through the guide mounting grooves 85 one by one and be fixed in place by screws, thus providing axial fixation and allowing the second water outlet bracket 8 to be movably mounted on the cleaning component 9. At the same time, during the rotation of the cleaning component 9, the guide mounting grooves 85 can restrict its rotation path and limit the extreme position of the cleaning component 9's rotation, thereby ensuring that the first inlet 911 or the second inlet 921 can be accurately aligned with the water outlet 841.

[0086] In one embodiment of this disclosure, reference is made to Figure 12 and Figure 14 A mounting post 72 is provided on the second water inlet bracket 7, and a washer-equipped screw 73 is provided on the top of the mounting post 72, such as... Figure 10 and Figure 11 As shown, the mounting post 72 penetrates the top of the first housing 1, and a washer screw 73 is fixedly connected to the top of the mounting post 72. The second water inlet bracket 7 is movably connected to the first housing 1 via the washer screw 73. Further, the second water inlet bracket 7 is configured to float with the first housing 1 via an elastic device 6. A second spring groove 74 is provided on the second water inlet bracket 7, and the second spring groove 74 can surround the outside of the mounting post 72. Figure 14 As shown, the elastic device 6 can be a spring, which can be sleeved on the mounting post 72, with its lower end extending into the second spring groove 74 and contacting the bottom surface of the second spring groove 74; the upper end of the spring can be connected to the first housing 1.

[0087] The cleaning component 9 is mounted below the second water inlet bracket 7 via the second water outlet bracket 8, and is thus floatingly connected to the first housing 1 via the elastic device 6. Under the elastic force of the elastic device 6, the second water inlet bracket 7 can cause the cleaning component 9 to float. During cleaning, the cleaning component 9 can adaptively float up and down by changing the vacuum level under different fabric conditions, thereby achieving automatic fabric cleaning and self-absorption, realizing labor-saving cleaning and improving cleaning efficiency.

[0088] In one embodiment of this disclosure, the second water inlet bracket 7 is axially guided to engage with the first housing 1. As described in Embodiment 1, an inwardly protruding limiting protrusion 14 is provided on the inner wall of the first housing 1, such as... Figure 14 As shown, a second limiting groove 76 extending axially is provided on the second water inlet bracket 7, and the limiting protrusion 14 can extend into the second limiting groove 76. In this way, on the one hand, it restricts the rotational freedom of the second water inlet bracket 7 relative to the first housing 1, and on the other hand, it provides space for the second water inlet bracket 7 to float in the axial direction relative to the first housing 1.

[0089] In one embodiment of this disclosure, reference is made to Figure 12 The second inlet bracket 7 is configured to be detachably connected to the second outlet bracket 8. As mentioned earlier, the bottom of the second inlet bracket 7 has an exposed opening. During installation, the user can align the extension 81 of the second outlet bracket 8 with the bottom opening of the second inlet bracket 7 and insert it into the second inlet bracket 7. The third sealing member 82, which is sleeved on the upper part of the extension 81, can cooperate with the inner wall of the second inlet bracket 7 to form a water channel seal. However, a cleaning member 9 is also installed at the bottom of the second outlet bracket 8. Under the action of gravity, the second outlet bracket 8 can easily detach from the second inlet bracket 7.

[0090] To solve the above problems, an additional detachable fixing structure is needed to ensure the stability of the cleaning component structure in the installed state. In one embodiment of this disclosure, see... Figure 12 The second housing 2, the second water outlet bracket 8, and the cleaning component 9 together form a detachable assembly, while the first housing 1 and the second water inlet bracket 7 together form a fixed assembly. Users can easily remove the detachable components from the fixed assembly, which facilitates the replacement and cleaning of the cleaning component 9.

[0091] Specifically, a mating groove 23 is provided on the second housing 2, and the bottom of the second water inlet bracket 7 includes a mounting portion 71, the configuration of which is adapted to the mating groove 23. In the state where the detachable assembly and the fixed assembly are connected, the mounting portion 71 is assembled within the mating groove 23. The mating groove 23 can be located above the second inner cavity 20, and the second water outlet bracket 8 is located in the second inner cavity 20, its extension 81 penetrating upwards through the bottom wall of the mating groove 23, thereby extending into the mating groove 23 to achieve water circuit connection in the assembled state. A magnet 711 is provided within the mounting portion 71, and a magnetic attracting element 22 is provided in the second inner cavity 20 of the second housing 2 at a position corresponding to the bottom wall of the mating groove 23. During assembly, the magnetic attracting element 22 is attracted by the magnet 711, thereby firmly embedding the mounting portion 71 into the mating groove 23, achieving a stable assembly relationship. Besides using magnetic attraction to achieve a detachable connection, other detachable structures known to those skilled in the art, such as snap-fit, threaded, or buckled connections, can also be used; this disclosure does not limit this to any particular method.

[0092] The above design solves the challenge of combining floating design with detachability. Specifically, this disclosure incorporates a floating design for the fixed assembly, with the second water inlet bracket 7 floatingly connected to the first housing 1 via an elastic device 6, while the detachable assembly itself is not floating. The second housing 2 in the detachable assembly is magnetically attached to the second water inlet bracket 7, thus achieving both quick disassembly and the ability for the cleaning component 9 to float up and down.

[0093] Furthermore, while the various structures of the fixed assembly are relatively fixed, the cleaning component 9, which enables water path switching, is part of the detachable assembly. It can rotate relative to the second housing 2 and the second water outlet bracket 8 within the detachable assembly, allowing for switching between the first water outlet channel 91 and the second water outlet channel 92 according to actual cleaning needs. This integrates quick-release, floating, and water path switching functions into the cleaning component.

[0094] Application Scenario 1 (corresponding to the cleaning component provided in Implementation Example 1) In home cleaning scenarios, users use a fabric cleaning machine to clean the surface of a sofa. Specifically, firstly, the cleaning component needs to achieve even water output to clean the large surface of the sofa; then, the cleaning component needs to achieve high-pressure water output to remove stubborn stains from the sofa; finally, the cleaning components need to be removed and the cleaning part 9 cleaned, and then reinstalled after cleaning.

[0095] When uniform water flow is required, the user controls the switching lever 52 to rotate to the first working position by turning the operating end 51, thereby putting the cleaning component and the water inlet component into a first coupling state. At this time, the switching lever 52 rotates relative to the first water inlet bracket 3 so that its first water inlet 521 is connected to the first passage 31, and rotates relative to the first water outlet bracket 4 so that its water outlet 523 is connected to the second passage 42, thereby opening the following passage: water inlet connector 13 → first passage 31 → switching passage 520 (first water inlet 521 → water outlet 523) → second passage 42 → first water outlet channel 91. The first water outlet channel 91 can be constructed as a ring, and multiple first outlets 912 arranged around the center can be opened at the bottom of the first water outlet channel 91. The first outlets 912 can be connected to multiple uniform water outlet nozzles, so that when the passage is opened, the multiple uniform water outlet nozzles spray water evenly, enabling the cleaning component to clean surface dirt.

[0096] When high-pressure water output is required, the user controls the switching lever 52 to rotate to the second working position by turning the operating end 51, thereby putting the cleaning component and the water inlet component into a second coupling state. The switching lever 52 rotates relative to the first water inlet bracket 3 to connect its second water inlet 522 with the first passage 31, and rotates relative to the first water outlet bracket 4 to connect its water outlet 523 with the third passage 43, thereby opening the following path: water inlet connector 13 → first passage 31 → switching passage 520 (second water inlet 522 → water outlet 523) → third passage 43 → second water outlet channel 92. The second water outlet channel 92 can be constructed as a straight line, thereby connecting the second inlet 921 to the second outlet 922, which can be connected to the high-pressure water spray head. When this path is open, the liquid from the second inlet 921 can flow along the straight second water outlet channel 92, thereby flowing quickly to the second outlet 922, and the high-pressure water spray head outputs water, enabling the cleaning component to achieve deep cleaning.

[0097] During the cleaning process, the cleaning component 9 conforms to the work surface, and under negative pressure, the wastewater generated during cleaning is sucked up by the cleaning assembly through the negative pressure suction port 15. The cleaning component, which is floatingly connected to the first housing 1, can adaptively float up and down based on the actual condition of the work surface (e.g., the material, flatness, hardness, etc.). By setting a cleaning component that is floatingly connected to the first housing 1, this disclosure eliminates the need for the user to scrape water downwards during cleaning. Instead, the cleaning component 9 can adaptively float up and down by changing the vacuum level under different fabric conditions, thereby achieving automatic fabric cleaning and self-absorption, realizing labor-saving cleaning and improving cleaning efficiency.

[0098] When disassembly is required, the user can unscrew the second housing 2 to unlock it, causing the latch 21 to disengage from the latch slot 34, thereby allowing the detachable assembly to be removed as a whole, and the lower end of the switching lever 52 to be pulled out of the second mounting slot 41. Specifically, the second housing 2, the first water outlet bracket 4, and the cleaning component 9 together form the detachable assembly, while the first housing 1, the first water inlet bracket 3, and the switching lever 52 together form the fixed assembly. The user can easily remove the detachable components from the fixed assembly, thus facilitating the replacement and cleaning of the cleaning component 9.

[0099] When installation is required, the user can insert the detachable assembly into the first inner cavity 10 of the first housing 1 and align the lower end of the switching rod 52 with the second mounting groove 41. The lower end of the switching rod 52 can be inserted into the second mounting groove 41. The snap-fit ​​21 extends into the snap-fit ​​groove 34 during the external force screwing process and is fixed. When the snap-fit ​​21 is connected to the snap-fit ​​groove 34, the outlet 523 of the switching rod 52 can communicate with the second passage 42 or the third passage 43.

[0100] Application Scenario 2 (corresponding to the cleaning component provided in Implementation Example 2) In home cleaning scenarios, users use a fabric cleaning machine to clean the surface of a sofa. Specifically, firstly, the cleaning component needs to achieve even water output to clean the large surface of the sofa; then, the cleaning component needs to achieve high-pressure water output to remove stubborn stains from the sofa; finally, the cleaning components need to be removed and the cleaning part 9 cleaned, and then reinstalled after cleaning.

[0101] When uniform water flow is required, the user rotates the cleaning component 9 to the third working position by switching the handle 95, thereby putting the cleaning component and the water inlet component into a first coupling state. At this time, the first inlet 911 can be rotated to communicate with the water outlet 841, so that the liquid flowing out of the water outlet 841 can flow into the first water outlet channel 91 through the first inlet 911. Specifically, the cleaning component in the first working position has the following pathway: water inlet connector 13 → liquid inlet connector 75 → fourth pathway (internal cavity of the second water inlet bracket 7) → fifth pathway (internal cavity of the extension 81) → water outlet 841 → first inlet 911 → first water outlet channel 91. The first water outlet channel 91 can be constructed as a ring, and multiple first outlets 912 arranged around the center can be opened at the bottom of the first water outlet channel 91. The first outlets 912 can be connected to multiple uniform water outlet nozzles, so that when this pathway is open, multiple uniform water outlet nozzles spray water evenly, enabling the cleaning component to clean surface dirt.

[0102] When high-pressure water output is required, the user rotates the cleaning component 9 to the fourth working position by switching the handle 95, thereby putting the cleaning component and the water inlet component into a second coupling state. At this time, the second inlet 921 can be rotated to communicate with the water outlet 841, so that the liquid flowing out of the water outlet 841 can flow into the second water outlet channel 92 through the second inlet 921. Specifically, the cleaning component in the first working position has the following pathway: water inlet connector 13 → liquid inlet connector 75 → fourth pathway (internal cavity of the second water inlet bracket 7) → fifth pathway (internal cavity of the extension 81) → water outlet 841 → second inlet 921 → second water outlet channel 92. The second water outlet channel 92 can be constructed as a straight line, thereby connecting the second inlet 921 to the second outlet 922, and the second outlet 922 can be connected to the high-pressure water spray head. When the passage is open, the liquid from the second inlet 921 can flow along the straight second outlet channel 92, thereby quickly flowing to the second outlet 922, where the high-pressure water nozzle sprays water, enabling the cleaning components to achieve deep cleaning.

[0103] During the cleaning process, the cleaning component 9 conforms to the work surface, and under negative pressure, the wastewater generated during cleaning is sucked up by the cleaning assembly through the negative pressure suction port 15. The cleaning component, which is floatingly connected to the first housing 1, can adaptively float up and down based on the actual condition of the work surface (e.g., the material, flatness, hardness, etc.). By setting a cleaning component that is floatingly connected to the first housing 1, this disclosure eliminates the need for the user to scrape water downwards during cleaning. Instead, the cleaning component 9 can adaptively float up and down by changing the vacuum level under different fabric conditions, thereby achieving automatic fabric cleaning and self-absorption, realizing labor-saving cleaning and improving cleaning efficiency.

[0104] The second housing 2, the second water outlet bracket 8, and the cleaning component 9 together form a detachable assembly, while the first housing 1 and the second water inlet bracket 7 together form a fixed assembly. Users can easily detach the detachable components from the fixed assembly, facilitating the replacement and cleaning of the cleaning component 9. When disassembly is required, the user can forcefully pull out the detachable assembly magnetically attached to the second water inlet bracket 7. Simultaneously, the upper end of the extension 81 of the second water outlet bracket 8 is pulled out of the second water inlet bracket 7.

[0105] When installation is required, the user can insert the detachable assembly into the first inner cavity 10 of the first housing 1, and align the extension 81 of the second water outlet bracket 8 with the bottom opening of the second water inlet bracket 7, thereby inserting the extension 81 into the second water inlet bracket 7. At the same time, the mounting part 71 is assembled in the mating groove 23, and the magnetic attracting member 22 can be attracted by the magnet 711, thereby making the mounting part 71 firmly embedded in the mating groove 23, achieving a stable assembly relationship.
