Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, specifically relating to a multi-functional cleaning machine and a control method for the cleaning machine. Background Technology

[0002] Existing cleaning equipment faces complex indoor cleaning scenarios. For example, there's a need to clean relatively smooth floor surfaces as well as relatively rough surfaces like carpets and rugs. Different surfaces require different types of roller brushes. For floors, highly absorbent brushes are used to wet-mop and remove dirt. For carpets, stiff brushes with high-speed rotation are needed to pat and vacuum away dust. To meet the different needs of floor and carpet cleaning, current technology typically provides continuous liquid supply for floor cleaning and stops supplying liquid for carpet cleaning. However, when there are localized stains on the carpet surface, cleaning liquid needs to be supplied to dissolve the dirt. The unsupplied carpet cleaning mode cannot meet the needs of carpet cleaning. Therefore, a liquid supply control method needs to be designed to simultaneously meet the cleaning needs of vacuuming and dissolving dirt in carpet cleaning. Summary of the Invention

[0003] This application provides a multi-functional cleaning machine and a control method for the cleaning machine, in order to solve the technical problem that the selection of cleaning strategies in existing cleaning equipment is relatively lagging, and that it is impossible to adjust the cleaning strategies in a timely and adaptive manner according to the actual situation when cleaning areas such as carpets that are prone to absorbing water.

[0004] The technical solution adopted in this application is as follows:

[0005] A multi-functional cleaning machine includes a floor brush and a liquid supply unit. The floor brush includes a floor brush body, a front cover detachably mounted on the floor brush body, a scraper assembly, and cleaning components. The cleaning components include a floor cleaning component and a carpet cleaning component, one of which is selectively mounted on the floor brush body. The machine also includes:

[0006] A water circuit control unit is linked to the liquid supply unit to control the liquid supply unit to stop supplying liquid to the carpet cleaning component when the carpet cleaning component is assembled on the floor brush body, and to control the liquid supply unit to supply liquid to the carpet cleaning component when the switch button on the handle of the cleaning machine is triggered for more than a preset time.

[0007] The multi-functional cleaning machine described in this application also includes the following additional technical features:

[0008] When the carpet cleaning component is assembled with the floor brush body, the liquid supply unit is triggered and supplies liquid to the carpet cleaning component at a flow rate of Q1. When the floor cleaning component is assembled with the floor brush body, the liquid supply unit supplies liquid to the floor cleaning component at a flow rate of Q2, wherein Q1>Q2.

[0009] The scraper assembly is movably installed. The cleaning machine also includes a triggering mechanism linked to the scraper assembly. The triggering mechanism is linked to the scraper assembly and is used to move the scraper assembly according to the type of cleaning component so that the scraper assembly is in a scraping state that is in contact with the floor cleaning component or in a avoidance state that is away from the carpet cleaning component.

[0010] The scraper assembly includes a scraping part that can cooperate with a cleaning component and a first linkage part that cooperates with a triggering mechanism. The triggering mechanism includes a first protrusion on the floor cleaning component, wherein the first protrusion cooperates with the first linkage part to put the scraping part in a scraping state that abuts against the floor cleaning component; or, the first protrusion is on the carpet cleaning component, wherein the first protrusion cooperates with the first linkage part to put the scraping part in a avoidance state that moves away from the carpet cleaning component.

[0011] The cleaning component includes a brush roller and a side plate. The brush roller is detachably mounted on the floor brush body via the side plate. The scraper assembly is movably mounted on the front cover. The first linkage part includes a positioning port through which the first protrusion passes. The first protrusion engages with the first linkage part to lock and fix the side plate to the floor brush body.

[0012] The floor brush body is provided with a transmission head that is connected to the cleaning component. The floor brush body is provided with a support plate near the transmission head. The scraper assembly is provided on the front cover. The scraper assembly includes a scraping part that can cooperate with the cleaning component and a second linkage part that cooperates with the triggering mechanism. The support plate is provided with a second protrusion that can cooperate with the second linkage part.

[0013] The scraper assembly is fixedly connected to the floor brush body, and the outer diameter of the carpet cleaning component is smaller than the outer diameter of the floor cleaning brush.

[0014] The scraper assembly includes a scraping component and a comb component, wherein the carpet cleaning component abuts against the comb component and is separate from the scraping component.

[0015] This application also discloses a control method for a cleaning machine, the cleaning machine including a floor brush body, a movable scraper assembly, cleaning components, and a liquid supply unit. The cleaning components include a floor cleaning component and a carpet cleaning component selectively installed on the floor brush body. The scraper assembly has a scraping state that abuts against the floor cleaning component and a avoidance state that moves away from the carpet cleaning component. The cleaning machine also includes a water circuit control unit. The control method includes:

[0016] Install the cleaning component and trigger the scraper assembly to move to the scraping state or the avoidance state during the installation process;

[0017] The water circuit control unit controls the liquid supply unit to supply liquid according to the type of cleaning component to meet the cleaning needs of the surface to be cleaned. When the carpet cleaning component is installed on the floor brush body, the liquid supply unit can be controlled to supply liquid to the carpet cleaning component by pressing and holding the handle of the cleaning machine.

[0018] The main body of the floor brush is provided with one of the Hall detection units or magnets, and the cleaning component is provided with the other of the Hall detection units or magnets.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] 1. The water circuit control unit in this application can operate in different states depending on the type of cleaning component installed in the floor brush body. First, the operating state of the cleaning machine is adjusted according to the type of cleaning component installed, improving the timeliness of response. Specifically, the water circuit control unit in this application can control the liquid supply unit to stop supplying liquid to the carpet cleaning component when the carpet cleaning component is assembled on the floor brush body. That is, the liquid supply strategy can be selected when the carpet cleaning component or floor cleaning component is installed, and the cleaning machine is operated at this time, which greatly improves cleaning efficiency and cleaning effect, and provides corresponding protection for the cleaning component itself and the surface to be cleaned. Second, when the carpet cleaning component is installed on the floor brush body, the liquid supply unit in this application is not limited to a state of not supplying liquid to the carpet cleaning component. When the carpet surface to be cleaned requires sufficient liquid to soften the dirt attached to it in order to achieve the corresponding cleaning effect, the water circuit control unit in this application can supply liquid according to the user's needs. Specifically, the cleaning machine's handle features a switch button for supplying liquid to the liquid supply unit. When the user presses the switch button for a preset time, it controls the liquid supply unit to soak and soften the dirt on the surface to be cleaned. When the user presses the switch button again or releases it, the liquid supply unit stops supplying liquid. This optimizes the cleaning strategy, improves cleaning efficiency, increases the cleaning machine's versatility, and enhances its practicality. Through a linkage mechanism, it is more suitable for cleaning needs in various scenarios and working conditions. The cleaning machine in this application is more user-friendly, providing users with an efficient, flexible, and easy-to-operate cleaning solution.

[0021] 2. In a preferred embodiment of this application, the liquid supply unit supplies liquid to the carpet cleaning component at a flow rate Q1 and to the floor cleaning component at a flow rate Q2, wherein Q1>Q2. This liquid supply method can better adapt to the water absorption characteristics of carpet surfaces. For example, carpets and blankets can usually absorb more water, while hard surfaces such as tiles or floors do not easily absorb water. Therefore, when the relatively large flow rate Q1 is used to supply liquid to the carpet cleaning component, it can better help the easily absorbent surfaces such as carpets and blankets to dissolve and soften dirt and dust, making it easier to remove dirt and dust attached to carpets and blankets. For hard surfaces such as floors and tiles, if the hard surfaces are kept wet for a long time, it may lead to material damage or an increased risk of slipping. Therefore, when the relatively small flow rate Q2 is used to supply liquid to the floor cleaning component, the drying time of the surface to be cleaned can be shortened, reducing or even avoiding potential problems.

[0022] 3. Cleaning components for floor cleaning have strong water absorption and dirt adsorption capabilities. Typically, a scraper assembly is installed on the floor brush to abut against the floor cleaning component, using the scraper assembly to remove dirt and liquid adhering to the floor cleaning component, reducing water residue on the floor. Cleaning components for carpet cleaning have stiff bristles, and their contact with the scraper assembly can cause abnormal noise during operation. Therefore, when installing floor cleaning and carpet cleaning components on the floor brush body, the two different types of cleaning components and the scraper assembly should have different positional relationships. The triggering mechanism in this application can move the scraper assembly according to the type of cleaning component, adaptively adjusting the position of the scraper assembly to adjust the cooperation between the scraper assembly and the cleaning component, enabling the cleaning machine to adapt to different types of surfaces to be cleaned. The ability to move the scraper assembly according to the type of cleaning component means that the triggering mechanism and the scraper assembly can be linked during the installation of the cleaning component, allowing the scraper assembly to move to the target state under the action of the triggering mechanism to better adapt to the material of the cleaning surface. Therefore, the linkage between the triggering mechanism and the scraper assembly caused by the installation of the cleaning component in this application improves the timeliness of response. The moment the cleaning component is installed, the scraper assembly is already matched to the appropriate working state. That is, once the cleaning component is installed, the scraper assembly is also ready to work with the cleaning component. Users can directly run the cleaning machine without having to perform any extra operations or pay enough attention to observe the status of the scraper assembly. The operation is convenient and quick, improving the user experience.

[0023] 4. In a preferred embodiment of this application, the triggering mechanism includes a first protrusion on the floor cleaning component or the carpet cleaning component, and the scraper assembly includes a scraping part and a first linkage part that cooperates with the triggering mechanism. The first protrusion and the first linkage part cooperate to place the scraper assembly in a scraping state that abuts against the floor cleaning component, or to place the scraper assembly in a avoidance state that moves away from the carpet cleaning component. In this embodiment, the mechanical linkage mechanism between the first protrusion and the first linkage part is realized during the switching process of the cleaning component. That is, when the user changes the cleaning component, there is no need to manually adjust the position of the scraper assembly. The linkage mechanism in this embodiment automatically completes this switching process, reducing the complexity of operation. The cooperation between the first protrusion and the first linkage part can achieve a rapid response, thereby controlling the position of the scraper assembly and enabling the scraper assembly to quickly enter the required working state, ensuring that the best usage and cleaning effect can be achieved in different cleaning modes. Moreover, this embodiment provides a seamless switching experience. During use, the user can focus more on the cleaning work itself without having to operate the scraper assembly. The installation of the cleaning component triggers the scraper assembly to complete the state switching, simplifying the usage process. Furthermore, this embodiment employs a mechanical linkage method, eliminating the need for electronic components, thereby improving the overall reliability of the cleaning machine, reducing the failure rate, and providing a foundation for future intelligent technology upgrades and functional expansions. Therefore, the linkage mechanism between the triggering mechanism and the scraper assembly in this embodiment simplifies operation, improves cleaning efficiency and adaptability, and enhances user-friendliness.

[0024] Furthermore, the scraper assembly is movably mounted on the front cover. The first linkage part has a positioning hole through which the first protrusion passes. The first protrusion can engage with the positioning hole to lock the side plate to the brush body, thereby securing the cleaning component. In this embodiment, the first linkage part and the first protrusion can not only switch the position of the scraper assembly through their mutual linkage, but also lock or unlock the side plate, thereby assembling and disassembling the cleaning component. In other words, this embodiment, through the cooperation of the first linkage part and the first protrusion, can achieve integrated operation of scraper assembly state switching and side plate locking or unlocking, simplifying the usage process and reducing the number of additional parts used to secure the cleaning component. This not only simplifies the overall design, but also reduces the likelihood of accidents during use due to the reduced number of parts, such as the loss of fasteners used to install the cleaning component. It also reduces the complexity of assembling and maintaining the cleaning component. In addition, securing the side plate by mechanical snap-fit ​​reduces the loosening of the side plate due to vibration or impact, improving the durability of the cleaning machine.

[0025] 5. In a preferred embodiment of this application, a support plate is provided at one end of the floor brush body near the transmission head that is connected to the cleaning component. A second protrusion is provided on the support plate. This second protrusion can be linked with a second linkage part on the scraper assembly, so that the scraper assembly is in a scraping state abutting against the floor cleaning component, or in a avoidance state away from the carpet cleaning component. By providing the second protrusion, which can be linked with the second linkage part, on the floor brush body, the position of the second protrusion is ensured, dynamic factors are reduced, and the relative position of the second protrusion and the second linkage part during the state switching process of the scraper assembly is more easily guaranteed. This makes the second linkage part easier to trigger, reduces the alignment difficulty during the interaction process, allows the scraper assembly to be precisely triggered, ensures the timeliness of the scraper assembly state switching, significantly reduces the user's operating difficulty, and improves the user experience.

[0026] In another embodiment, where the cleaning machine has both a first protrusion and a second protrusion, and the scraper assembly has both a first linkage and a second linkage, the cooperation between the first protrusion and the first linkage, together with the cooperation between the second protrusion and the second linkage, can further ensure the reliability of the scraper assembly in randomly switching states during the installation of the cleaning components. This avoids the phenomenon that the scraper assembly's state switching is not timely due to a problem with one of the linkage mechanisms. It not only simplifies the adjustment process, but also enhances the reliability and stability of the entire machine.

[0027] In a preferred embodiment of this application, the triggering mechanism includes at least two elastic structures symmetrically arranged along the length of the scraper assembly, and at least two sets of guide structures symmetrically arranged along the length of the scraper assembly. The symmetrical arrangement of the elastic structures helps provide a balanced restoring force to the scraper assembly, thereby facilitating rapid switching between scraping and avoidance states. The guide structures provide movement guidance and a clear movement path for the scraper assembly during state switching, preventing tilting, jamming, or deviation from the predetermined path during movement. This ensures the scraper assembly maintains precision, smoothness, and consistency in movement during multiple switching processes, thus ensuring the stability and reliability of the scraper assembly's state switching. Furthermore, the symmetrical arrangement of the elastic and guide structures helps reduce uneven wear of the scraper assembly due to prolonged use, extending its service life and reducing the maintenance costs of the cleaning machine.

[0028] 6. This application designs a scraper assembly that is fixedly connected to the main body of the floor brush. By making the outer diameter of the carpet cleaning component smaller than that of the floor cleaning component, the carpet cleaning component is at least partially separated from the scraper assembly when it is installed in the main body of the floor brush, reducing the abnormal noise generated by the carpet cleaning component hitting the scraper assembly during rotation. At the same time, the floor cleaning component with a larger outer diameter at least partially abuts against the scraper assembly, satisfying the requirement that the scraper assembly scrapes the cleaning component during the rotation of the floor cleaning component.

[0029] 7. To improve the hair removal capability of the scraper assembly, the scraper assembly may include a scraping component and a comb component. The scraping component and the comb component are arranged vertically and extend towards the cleaning component. For the same cleaning component, the comb component is closer to the cleaning component than the scraping component. When the floor cleaning component is installed in the floor brush body, both the scraping component and the comb component are interference-fitted with the floor cleaning component, with the interference of the scraping component being greater than that of the comb component. When the carpet cleaning component is installed in the floor brush body, the scraping component separates from the carpet cleaning component, and the comb component at least partially abuts against the carpet cleaning component to remove filamentous debris from the carpet cleaning component. Optionally, to reduce abnormal noise during the operation of the cleaning machine, the comb component is made of a relatively low-hardness plastic material.

[0030] 8. This application also discloses a control method for a cleaning machine. The control method includes: installing a cleaning component and triggering the scraper assembly to move to a scraping state or an avoidance state during the installation process; the water circuit control unit of the cleaning machine controls the liquid supply unit to supply liquid according to the type of cleaning component to adapt to the cleaning needs of the surface to be cleaned; and when the carpet cleaning component is installed on the floor brush body, the liquid supply unit is controlled to supply liquid to the carpet cleaning component by pressing and holding the handle of the cleaning machine. Under this control method, the switching of the scraper assembly position and the selection of the cleaning strategy are both realized during the installation process of the cleaning component. That is, when the carpet cleaning component or floor cleaning component is installed, the cleaning machine can automatically select the liquid supply strategy, and the state of the scraper assembly is also matched. At this time, when the cleaning machine is run, it can clean the surface to be cleaned according to the type of cleaning component, the matching state of the scraper assembly, and the appropriate cleaning strategy, which greatly improves the cleaning efficiency and the cleaning effect, and provides corresponding protection for the cleaning component itself and the surface to be cleaned, thus improving user-friendliness.

[0031] 9. This application sets Hall effect sensors or magnets on the cleaning component and the floor brush body that is installed in conjunction with the cleaning component to monitor the installation type of the cleaning component. This method is low-cost and can accurately obtain results when the cleaning component is fully assembled. Attached Figure Description

[0047] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0048] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0051] Example 1:

[0052] like Figures 1 to 3 , Figure 12 As shown, a multi-functional cleaning machine includes a floor brush and a liquid supply unit. The floor brush includes a floor brush body 3, a front cover 4 detachably mounted on the floor brush body 3, a scraper assembly 5, and cleaning components. The cleaning components include a floor cleaning component 1 and a carpet cleaning component 2, with one of the floor cleaning component 1 and the carpet cleaning component 2 selectively mounted on the floor brush body 3. The machine also includes:

[0053] The water circuit control unit is linked with the liquid supply unit to control the liquid supply unit to stop supplying liquid to the carpet cleaning component 2 when the carpet cleaning component 2 is assembled on the floor brush body 3, and to control the liquid supply unit to supply liquid to the carpet cleaning component 2 when the switch button on the handle of the cleaning machine is triggered for more than a preset time.

[0054] This application provides a cleaning machine that can clean carpets and floors in various scenarios simply by changing the cleaning components. Due to the different installation types of the cleaning components, the water circuit control unit has different control logic.

[0055] In a preferred embodiment, a detection unit is provided at the mating position of the cleaning component and the floor brush body. Based on the installation type of the cleaning component detected by the detection unit, the water circuit control unit controls the liquid supply according to the information detected by the detection unit. Compared with the prior art, this solution allows for timely selection of the control strategy by the water circuit control unit. Specifically, the water circuit control unit in this application can control the liquid supply unit to stop supplying liquid to the carpet cleaning component 2 when the carpet cleaning component 2 is assembled into the floor brush body 3; that is, the liquid supply strategy can be selected when the carpet cleaning component 2 or the floor cleaning component 1 is installed. This significantly improves cleaning efficiency and effect, and provides corresponding protection for both the cleaning component itself and the surface to be cleaned.

[0056] Another difference between this application and existing technologies is that, when the carpet cleaning component 2 is installed on the brush body 3, the liquid supply unit in this application is not limited to a state where it cannot supply liquid to the carpet cleaning component 2. When the carpet surface awaiting cleaning requires sufficient liquid to soften the dirt adhering to it in order to achieve the corresponding cleaning effect, the water circuit control unit in this application can also control the liquid supply unit to supply liquid to the carpet cleaning component 2 when the switch button on the cleaning machine handle is triggered after a preset time. This allows the cleaning machine to supply liquid to the area to be cleaned through its own liquid supply unit when the carpet cleaning component 2 is assembled on the brush body 3, optimizing the cleaning strategy, improving cleaning efficiency, increasing the versatility of the cleaning machine, and enhancing its practicality. Through the linkage mechanism, it is more suitable for cleaning needs in multiple scenarios and under multiple working conditions. The cleaning machine in this application is more user-friendly, providing users with an efficient, flexible, and easy-to-operate cleaning solution. Specifically, the cleaning machine handle is also equipped with a switch button to control the liquid supply unit's liquid supply / disabling function. When the carpet cleaning component 2 is assembled with the floor brush body 3, the water circuit control unit controls the liquid supply unit to stop supplying liquid. At this time, dust is collected only by the rotation and beating of the carpet by the carpet cleaning component 2. When local dirt appears on the carpet and needs to be dissolved and cleaned with liquid, the user can press the switch button. When the switch button is triggered for more than a preset time, the liquid supply unit will be controlled to supply liquid.

[0057] As an optional solution in this embodiment, the switch button can be a trigger button with a fixed liquid supply duration. That is, when the user triggers the switch button once, the liquid supply unit continuously supplies liquid for a first preset duration, which can be any suitable time for carpet cleaning, such as 15s, 30s, 1min, or 3min.

[0058] As an optional solution in this embodiment, the switch button can be an on / off trigger button, that is, when the user presses the switch button for more than a preset time, the liquid supply unit is controlled to supply liquid, and when the user presses the switch button again for more than a preset time, the liquid supply unit is controlled to stop supplying liquid.

[0059] As an optional solution in this embodiment, the switch button can be a trigger-type button, meaning that if the user presses the switch button for a preset time, the liquid supply unit will be controlled to supply liquid. In carpet cleaning mode, if the user wants to control the liquid supply unit, they need to keep pressing the switch button to obtain a continuous liquid flow. When the user stops pressing the switch button, the liquid supply unit stops supplying liquid.

[0060] Those skilled in the art will know that the switch button used to control the opening and closing of the liquid supply unit in carpet cleaning mode can be a physical, pressable mechanical button or a touch button. It can be an independent button used only to control the liquid supply unit or an integrated button that integrates other functions.

[0061] When the carpet cleaning component 2 is assembled with the floor brush body 3, the liquid supply unit is triggered and supplies liquid to the carpet cleaning component 2 at a flow rate of Q1. When the floor cleaning component 1 is assembled with the floor brush body 3, the liquid supply unit supplies liquid to the floor cleaning component 1 at a flow rate of Q2.

[0062] In one implementation, Q1 = Q2, meaning that the liquid supply flow rate of the liquid supply unit is equal or approximately equal in both carpet cleaning mode and floor cleaning mode.

[0063] In another implementation, Q1 > Q2. This liquid supply method is better adapted to the water absorption characteristics of the surface to be cleaned. For example, carpets and blankets can usually absorb more water, while hard surfaces such as tiles or floors do not easily absorb water. Therefore, when liquid is supplied to the carpet cleaning unit 2 with a relatively large flow rate of Q1, it can better help the easily absorbent surfaces such as carpets and blankets to dissolve and soften dirt and dust, making it easier to remove dirt and dust attached to carpets and blankets. For hard surfaces such as floors and tiles, if the hard surface is kept wet for a long time, it may lead to material damage or an increased risk of slipping. Therefore, when liquid is supplied to the floor cleaning unit 1 with a relatively small flow rate of Q2, the drying time of the surface to be cleaned can be shortened, reducing or even avoiding potential problems.

[0064] In another implementation, during the floor cleaning process, the carpet cleaning component rotates at a speed of V1, and the floor cleaning component rotates at a speed of V2, where V1 > V2. The rapidly rotating carpet cleaning component pats the carpet, raising dust scattered on the carpet, which is then collected in the cleaning machine. The relatively slower rotating floor cleaning component rubs and wipes the floor, adhering to dirt on the surface.

[0065] In another embodiment, the cleaning machine also includes a suction motor and a suction port for generating suction force. To improve the suction power of the carpet cleaning mode, the power of the suction motor in the carpet cleaning mode is P1, and the power of the suction motor in the floor cleaning mode is P2, where P1 > P2.

[0066] like Figures 1 to 3 As shown, a multi-functional cleaning machine includes a floor brush and a liquid supply unit. The floor brush includes a floor brush body 3, a front cover 4 detachably mounted on the floor brush body 3, a scraper assembly 5, and cleaning components. The cleaning components include a floor cleaning component 1 and a carpet cleaning component 2, with one of the floor cleaning component 1 and the carpet cleaning component 2 selectively mounted on the floor brush body 3. The machine also includes:

[0067] The triggering mechanism is linked with the scraper assembly 5 and is used to move the scraper assembly 5 according to the type of cleaning component so that the scraper assembly 5 is in a scraping state that is in contact with the floor cleaning component 1 or in a avoidance state that is away from the carpet cleaning component 2.

[0068] The water circuit control unit is linked with the liquid supply unit to control the liquid supply unit to stop supplying liquid to the carpet cleaning component 2 when the carpet cleaning component 2 is assembled on the floor brush body 3, and to control the liquid supply unit to supply liquid to the carpet cleaning component 2 when the switch button on the handle of the cleaning machine is triggered for more than a preset time.

[0069] In the process where the water circuit control unit controls the liquid supply unit to supply liquid according to the type of cleaning component to meet the cleaning requirements of the surface to be cleaned, the determination of the type of cleaning component includes, but is not limited to, the following implementation methods:

[0070] Method 1: The water circuit control unit includes a first detection element for detecting the state of the scraper assembly 5. Since the state of the scraper assembly 5 matches the type of cleaning component, the type of cleaning component is determined by detecting the state of the scraper assembly 5. The detection of the state of the scraper assembly 5 can, for example, detect the position of the scraping portion 51 or the first linkage portion 52 on the scraper assembly 5. The first detection element can be a micro switch, proximity switch, photoelectric sensor, etc.

[0071] Method 2: The water circuit control unit includes a second detection element. During the installation of the carpet cleaning component 2 or the floor cleaning component 1, the second detection element can be triggered by a triggering mechanism to determine the type of cleaning component. For example, the second detection element is a micro switch, and the triggering mechanism includes a first protrusion 12 provided on the side plate 11 of the carpet cleaning component 2 or the floor cleaning component 1. During the installation of the carpet cleaning component 2 or the floor cleaning component 1, the first protrusion 12 can contact to trigger the micro switch, thereby determining the type of cleaning component based on the detection result of the second detection element.

[0072] Method 3: The water circuit control unit also includes a third detection element located in the brush body 3. The floor cleaning component 1 and / or carpet cleaning component 2 are equipped with a trigger element capable of triggering the third detection element. The water circuit control unit determines the installation status of the cleaning component based on the feedback signal from the third detection element. For example, a magnetic component is provided inside the carpet cleaning component 2, and the third detection element is a Hall sensor located in the brush body 3. When the carpet cleaning component 2 is installed on the brush body 3, the Hall sensor detects the magnetic component, thereby determining that the type of cleaning component is carpet cleaning component 2. The water circuit control unit controls the liquid supply unit to stop supplying liquid to the carpet cleaning component 2, and controls the liquid supply unit to supply liquid to the carpet cleaning component 2 when the switch button on the handle of the cleaning machine is triggered for more than a preset time.

[0073] The floor cleaning component 1 and carpet cleaning component 2 of this application can be selectively installed on the brush body 3 to adapt to the cleaning needs of different surfaces. For example, when cleaning hard surfaces such as floors and tiles, the floor cleaning component 1 is installed on the brush body 3; when cleaning soft surfaces such as carpets and rugs, the carpet cleaning component 2 is installed on the brush body 3. Preferably, the floor cleaning component 1 is a soft-bristled roller brush, and the carpet cleaning component 2 is a hard-bristled roller brush. The scraper assembly 5 is movable, and its state can be adjusted to match the use of the cleaning components. This prevents interference between the scraper assembly 5 and the carpet cleaning component 2 during use, thereby reducing noise during the operation of the carpet cleaning component 2.

[0074] The triggering mechanism in this application can move the scraper assembly 5 according to the type of cleaning component, adaptively adjusting its position to suit the type of cleaning component. This adjusts the relationship between the scraper assembly 5 and the cleaning component, enabling the cleaning machine to adapt to different types of surfaces to be cleaned. The ability to move the scraper assembly 5 according to the type of cleaning component means that the triggering mechanism and scraper assembly 5 can be linked during the installation process, allowing the scraper assembly 5 to move to the target state under the triggering mechanism's influence, better adapting to the material of the cleaning surface. Therefore, the linkage between the triggering mechanism and scraper assembly 5 caused by the installation of the cleaning component in this application improves the timeliness of response. The moment the cleaning component is installed, the scraper assembly 5 is already matched to the appropriate working state; that is, once the cleaning component is installed, the scraper assembly 5 is ready to work in conjunction with it. Users can directly operate the cleaning machine without additional operation or sufficient attention to observe the status of the scraper assembly 5, making operation convenient and quick, and improving the user experience.

[0075] It should be noted that both the cleaning component and the front cover 4 in this application can be detachably installed on the brush body 3. Therefore, when changing the type of cleaning component, the installation process of the cleaning component varies depending on the model. That is, the "installation process of the cleaning component" mentioned above, which states that "the linkage between the trigger mechanism and the scraper assembly 5 can be realized during the installation process of the cleaning component", is not limited to its literal meaning depending on the actual application model.

[0076] In one embodiment, the disassembly and assembly of the cleaning component requires the disassembly and assembly of the front cover 4 as well. That is, when disassembling the cleaning component, the front cover 4 must first be removed before the cleaning component can be taken out. When installing the cleaning component, the cleaning component is installed first, and then the front cover 4 is installed in place. Therefore, for the cleaning machine in this embodiment, the "cleaning component installation process" in the phrase "the linkage between the trigger mechanism and the scraper assembly 5 can be realized during the cleaning component installation process" refers to the installation process of the front cover 4 after the cleaning component is installed in place.

[0077] In another embodiment, the disassembly and assembly of the cleaning component does not involve the disassembly and assembly of the front cover 4. That is, the front cover 4 does not interfere with the disassembly and assembly of the cleaning component. Therefore, relative to the dynamic operation during the disassembly and assembly of the cleaning component, the front cover 4 is fixedly installed on the floor brush body 3 during this process. When changing the type of cleaning component, only the cleaning component needs to be disassembled and assembled. Therefore, for the cleaning machine in this embodiment, the "cleaning component installation process" in the phrase "the linkage between the trigger mechanism and the scraper assembly 5 can be realized during the cleaning component installation process" refers to the cleaning component installation process in its surface sense.

[0078] Example 2:

[0079] Based on Embodiment 1, this application, to further ensure the universality of carpet cleaning and floor cleaning components on the same brush body, designs a movable scraper assembly and a triggering mechanism that works in conjunction with the scraper assembly. The linkage between the scraper assembly 5 and the triggering mechanism can be any of the following embodiments:

[0080] Method 1: For example Figures 1 to 5 As shown, the scraper assembly 5 includes a scraping part 51 that can cooperate with the cleaning component and a first linkage part 52 that cooperates with the triggering mechanism. The triggering mechanism includes a first protrusion 12 provided on the floor cleaning component 1. The first protrusion 12 cooperates with the first linkage part 52 to make the scraping part 51 in a scraping state that abuts against the floor cleaning component 1; or, the first protrusion 12 is provided on the carpet cleaning component 2. The first protrusion 12 cooperates with the first linkage part 52 to make the scraping part 51 in a avoidance state that moves away from the carpet cleaning component 2.

[0081] In Method 1, the mechanical linkage mechanism between the first protrusion 12 and the first linkage part 52 is implemented during the switching process of the cleaning component. That is, when the user changes the cleaning component, there is no need to manually adjust the position of the scraper assembly 5. The linkage mechanism in this Method 1 automatically completes this switching process, reducing operational complexity. The cooperation between the first protrusion 12 and the first linkage part 52 enables rapid response and precise control of the scraper assembly 5's position, allowing it to quickly enter the required working state and ensuring optimal usage and cleaning effects in different cleaning modes. Furthermore, this Method 1 provides a seamless switching experience, allowing users to focus more on the cleaning work itself without additional operation of the scraper assembly 5. The installation of the cleaning component triggers the scraper assembly 5 to complete the state switch, simplifying the usage process. In addition, this Method 1 uses a mechanical linkage method, eliminating the need for electronic components, thereby improving the overall reliability of the cleaning machine, reducing the failure rate, and providing a foundation for future intelligent technology upgrades and functional expansion. Therefore, the linkage mechanism between the triggering mechanism and the scraper assembly 5 in this embodiment simplifies operation, improves cleaning efficiency and adaptability, and enhances user-friendliness.

[0082] When the first protrusion 12 is provided on the floor cleaning component 1, the initial position of the scraper assembly 5 is away from the installation area on the brush body 3 where the cleaning component is installed. During the process of installing the floor cleaning component 1 onto the brush body 3, the first protrusion 12 cooperates with the first linkage 52 to drive the scraper assembly 5 to move, so that the scraper assembly 5 moves from the initial position to a scraping state that can abut against the floor cleaning component 1. However, since the carpet cleaning component 2 does not have the first protrusion 12, when the carpet cleaning component 2 is assembled onto the brush body 3, the first linkage 52 is not triggered, and the scraper assembly 5 remains in the initial position, thus avoiding interference with the carpet cleaning component 2.

[0083] When the first protrusion 12 is provided on the carpet cleaning component 2, the initial position of the scraper assembly 5 is close to the installation area on the brush body 3 for installing the cleaning component. More specifically, this initial position is such that when the floor cleaning component 1 is installed onto the brush body 3, the floor cleaning component 1 can directly contact the scraper assembly 5 so that the scraper assembly 5 is in a scraping state. Since the first protrusion 12 is provided on the carpet cleaning component 2, during the process of installing the carpet cleaning component 2 onto the brush body 3, the first protrusion 12 cooperates with the first linkage part 52 to drive the scraper assembly 5 to move, so that the scraper assembly 5 moves from the initial position to a state of avoidance away from the carpet cleaning component 2, thereby avoiding mutual interference between the scraper assembly 5 and the carpet cleaning component 2.

[0084] In Method 1, after the cleaning component is installed onto the brush body 3, to prevent it from detaching from the brush body 3 during use, any of the following embodiments can be used to achieve locking and fixing of the cleaning component after it is installed in place:

[0085] Option 1: As Figure 4 and Figure 5 As shown, the cleaning component includes a brush roller 13 and a side plate 11. The brush roller 13 is detachably mounted on the floor brush body 3 via the side plate 11. The scraper assembly 5 is movably mounted on the front cover 4. The first linkage part 52 includes a positioning port 521 through which the first protrusion 12 passes. The first protrusion 12 engages with the first linkage part 52 to lock and fix the side plate 11 to the floor brush body 3.

[0086] In this embodiment 1, the first linkage part 52 and the first protrusion 12 can not only switch the position of the scraper assembly 5 through their mutual linkage, but also lock or unlock the side plate 11, thereby realizing the assembly and disassembly of the cleaning component. In other words, through the cooperation of the first linkage part 52 and the first protrusion 12, Scheme 1 can realize the integrated operation of switching the state of the scraper assembly 5 and locking or unlocking the side plate 11, simplifying the usage process and reducing the number of additional parts used to fix the cleaning component. This not only simplifies the overall design, but also reduces the possibility of accidents during use due to the reduced number of parts, such as the loss of fasteners used to install the cleaning component. It also reduces the complexity of assembling and maintaining the cleaning component. In addition, fixing the side plate 11 by mechanical snap-fit ​​can reduce the loosening of the side plate 11 caused by vibration or impact, improving the durability of the cleaning machine.

[0087] In Scheme 1, both the cleaning component and the front cover 4 can be detachably installed on the brush body 3. Scheme 1 does not limit the installation order of the cleaning component and the front cover 4. Under different installation orders, the setting and engagement of the first linkage part 52 and the first protrusion 12 are slightly different, as follows:

[0088] Example 1: The cleaning component is installed on the brush body 3 before the front cover 4. That is, when changing the type of cleaning component, the cleaning component is installed on the brush body 3 first. After the cleaning component is installed, the front cover 4 is then installed on the brush body 3. During the installation of the front cover 4, the first linkage part 52 and the first protrusion 12 drive the scraper assembly 5 to move, thus achieving state switching. In this Example 1, the cleaning component moves along the first direction X to be assembled onto the brush body 3, the front cover 4 moves along the second direction Z, which is perpendicular to the first direction X, to be assembled onto the brush body 3, and the scraper assembly 5 moves along the third direction Y, which is perpendicular to both the first direction X and the second direction Z, to achieve state switching.

[0089] The following example, taking the first protrusion 12 located on the side plate 11 of the floor cleaning component 1, will be used to specifically explain the cooperation method between the first linkage part 52 and the first protrusion 12 in this example 1.

[0090] like Figure 1 , Figure 4 and Figure 5As shown, the side panel 11 of the floor cleaning component 1 is provided with a first protrusion 12 on one side, and the scraper assembly 5 is provided with a first linkage part 52. One of the first protrusion 12 and the first linkage part 52 is provided with a drive groove, and the other of them is provided with a drive protrusion that can extend into the drive groove. One of the drive groove and the drive protrusion is provided with a first drive inclined surface 121, and the other is provided with a first mating surface. During the relative movement between the front cover 4 and the cleaning component, the scraper assembly 5 is driven to move by the cooperation of the first drive inclined surface 121 and the first mating surface, so that the scraper assembly 5 moves to a scraping state that can abut against the floor cleaning component 1.

[0091] As a preferred option, such as Figure 1 and Figure 4 As shown, the first linkage part 52 is provided with a vertically penetrating positioning port 521, which forms a drive groove. The first protrusion part 12 is provided with a drive protrusion extending in the vertical direction, which is provided with a first drive inclined surface 121. During the process of assembling the front cover 4 to the floor brush body 3 in the second direction Z, the drive protrusion extends into the positioning port 521 and drives the first linkage part 52 to move in the third direction Y through the first drive inclined surface 121, thereby driving the scraper assembly 5 to move in the third direction Y to the scraping state.

[0092] Example 2: The front cover 4 is installed on the brush body 3 before the cleaning component. That is, when changing the type of cleaning component, it is not necessary to remove the front cover 4; only the cleaning component needs to be removed and installed. In this Example 2, the cleaning component moves along the first direction X to assemble into the brush body 3, and the scraper assembly 5 moves along the third direction Y, which is perpendicular to the first direction X, to achieve state switching.

[0093] The following example, taking the first protrusion 12 located on the side plate 11 of the floor cleaning component 1, will be used to specifically illustrate the cooperation method between the first linkage part 52 and the first protrusion 12 in this Example 2.

[0094] like Figure 9 As shown, the side panel 11 of the floor cleaning component 1 is provided with a first protrusion 12 on one side, and the scraper assembly 5 is provided with a first linkage part 52. One of the first protrusion 12 and the first linkage part 52 is provided with a drive groove, and the other of them is provided with a drive protrusion that can extend into the drive groove. One of the drive groove and the drive protrusion is provided with a first drive inclined surface 121, and the other is provided with a first mating surface 56. During the relative movement between the front cover 4 and the cleaning component, the scraper assembly 5 is driven to move by the cooperation of the first drive inclined surface 121 and the first mating surface 56, so that the scraper assembly 5 moves to a scraping state that can abut against the floor cleaning component 1.

[0095] Specifically, the first linkage part 52 has an opening facing the side plate 11, which forms a drive groove. The first protrusion part 12 has a drive protrusion extending along the first direction X. The drive protrusion has a first drive inclined surface 121. During the process of assembling the cleaning component to the floor brush body 3 along the first direction X, the drive protrusion extends into the opening and drives the first linkage part 52 to move along the third direction Y through the first drive inclined surface 121, thereby driving the scraper assembly 5 to move along the third direction Y to the scraping state.

[0096] Option 2: The cleaning components include a brush roller 13 and a side plate 11. The brush roller 13 is detachably mounted on the floor brush body 3 via the side plate 11. The scraper assembly 5 is movably mounted on the front cover 4. One of the side plate 11 and the floor brush body 3 is provided with a magnetic component, and the other is provided with a mating component adapted to the magnetic component. The magnetic attraction between the magnetic component and the mating component keeps the side plate 11 in a position where it is attracted to the floor brush body 3.

[0097] Scheme 2 does not limit the mating parts: in one example, the mating part is a ferromagnetic or other metal structure that can interact with the magnetic part; in another example, the mating part is also a magnetic structure that is itself magnetic, but the arrangement of the magnetic poles of the mating part is exactly the opposite of the arrangement of the magnetic poles of the magnetic part, so as to attract the side plate 11 to the brush body 3 by the attraction of opposite poles.

[0098] Option 3: The cleaning components include a brush roller 13 and a side plate 11. The brush roller 13 is detachably mounted on the floor brush body 3 via the side plate 11. The scraper assembly 5 is movably mounted on the front cover 4. The floor brush body 3 is provided with a mounting groove that matches the side plate 11. When the side plate 11 is assembled to the floor brush body 3, there is an interference fit between the side plate 11 and the mounting groove.

[0099] Option 4: The floor brush housing is equipped with a locking component, which is movably configured relative to the floor brush body 3 to have a locked state when locked with the side plate 11 and an unlocked state when disengaged from the side plate 11. In a specific example, a protruding positioning part can be provided on one side of the side plate 11, with a positioning hole on the positioning part. The locking component includes a telescopic locking rod. When the side plate 11 is installed on the floor brush body 3, the locking rod extends into the positioning hole to lock and fix the side plate 11. When it is necessary to disassemble the cleaning component, the locking rod is retracted by external force to move out of the positioning hole, thereby unlocking.

[0100] Method 2: For example Figures 6 to 8As shown, the floor brush body 3 is equipped with a transmission head that is connected to the cleaning component. A support plate 31 is located near the transmission head on one end of the floor brush body 3. The scraper assembly 5 is mounted on the front cover 4. The scraper assembly 5 includes a scraping part 51 that cooperates with the cleaning component and a second linkage part 53 that cooperates with the triggering mechanism. The support plate 31 is equipped with a second protrusion 32 that cooperates with the second linkage part 53. By placing the second protrusion 32, which can cooperate with the second linkage part 53, on the floor brush body 3, the position of the second protrusion 32 is ensured, dynamic factors are reduced, and the relative position of the second protrusion 32 and the second linkage part 53 during the state switching process of the scraper assembly 5 is more easily guaranteed. This makes the second linkage part 53 easier to trigger, reduces the alignment difficulty during the cooperation process, and enables the scraper assembly 5 to be triggered accurately. This ensures the timeliness of the scraper assembly 5's state switching, significantly reduces the user's operational difficulty, and enhances the user experience.

[0101] Method two does not limit the movement of the second protrusion 32, and it can adopt any of the following embodiments:

[0102] Option 5: The second protrusion 32 can swing relative to the support plate 31 to have a triggered state that cooperates with the second linkage part 53 and a stored state that is separated from the second linkage part 53.

[0103] Option 6: As Figure 7 and Figure 8 As shown, the second protrusion 32 is movably disposed on the support plate 31, having a triggered state that can cooperate with the second linkage part 53 and a retracted state that is separated from the second linkage part 53. That is, in embodiment 6, the second protrusion 32 can extend and retract along the support plate 31 to cooperate with or separate from the second linkage part 53.

[0104] Regardless of whether it is scheme 5 or scheme 6, the driving of the second protrusion 32 can be implemented in the following way: such as Figure 7 and Figure 8 As shown, the support plate 31 is also provided with a third protrusion 33 that cooperates with the cleaning component. The second protrusion 32 and the third protrusion 33 are connected in a transmission manner. When the floor cleaning component 1 or the carpet cleaning component 2 is assembled to the floor brush body 3, the cleaning component pushes the third protrusion 33 to move and drives the second linkage part 53 to move through the third protrusion 33, so that the scraper assembly 5 is in a scraping state or an avoidance state.

[0105] Preferably, the third protrusion 33 moves linearly along the assembly direction of the cleaning part. Through the transmission cooperation between the third protrusion 33 and the second protrusion 32, it is converted into linear feed motion or oscillation of the second protrusion 32, thereby driving the second linkage part 53 to move.

[0106] In a specific example, such as Figure 7 and Figure 8As shown, one of the second protrusion 32 and the third protrusion 33 is provided with a second driving slope, and the other is provided with a second mating surface adapted to the second driving slope. The third protrusion 33 makes a linear feed motion under the push of the cleaning component, and drives the second protrusion 32 to move upward through the cooperation of the second driving slope and the second mating surface. One of the second protrusion 32 and the second linkage part 53 is provided with a third driving slope, and the other is provided with a third mating surface. When the second protrusion 32 moves upward, the second linkage part 53 is driven to move through the transmission of the third driving slope and the third mating surface, thereby driving the scraper assembly 5 to move.

[0107] Furthermore, the support plate 31 is also provided with an elastic reset member 34 for applying a restoring force to the second protrusion 32. The elastic reset member 34 can be, for example, a spring. When the carpet cleaning part 2 or the floor cleaning part 1 is removed from the floor brush body 3, the third protrusion 33 is no longer pushed up. Under the restoring force of the elastic reset member 34, the second protrusion 32 moves downward, thereby driving the third protrusion 33 to reset, so as to be triggered again.

[0108] The cleaning component can push against the third protrusion 33 using any of the following examples:

[0109] Example 3: The floor cleaning component 1 or the carpet cleaning component 2 is provided with a radially outward protruding squeezing part. During the installation of the cleaning component, the protruding squeezing part pushes the third protrusion 33 to move, so as to ultimately drive the scraper assembly 5 to achieve state switching.

[0110] Example 4: The cleaning component includes a brush roller 13 and brush bristles. The diameter of the brush roller 13 of the floor cleaning component 1 is larger than that of the brush roller 13 of the carpet cleaning component 2, so that the brush roller 13 of the floor cleaning component 1 abuts against the third protrusion 33. That is, in this Example 4, the position of the third protrusion 33 is such that when the floor cleaning component 1 is installed onto the floor brush body 3, the brush roller 13 of the floor cleaning component 1 can contact and push the third protrusion 33 to move, thereby driving the scraper assembly 5 to switch states; while during the installation of the carpet cleaning component 2, because the diameter of the brush roller 13 of the carpet cleaning component 2 is relatively small, the carpet cleaning component 2 cannot push the third protrusion 33 to move, thereby not driving the scraper assembly 5 to move.

[0111] Method 3: For example Figures 1 to 8As shown, the scraper assembly 5 includes a scraping part 51 that can cooperate with the cleaning component and a first linkage part 52 and a second linkage part 53 that cooperate with a triggering mechanism. The triggering mechanism includes a first protrusion 12 on the floor cleaning component 1, which cooperates with the first linkage part 52 to put the scraper assembly 5 in a scraping state that abuts against the floor cleaning component 1; or, the first protrusion 12 is provided on the carpet cleaning component 2, which cooperates with the first linkage part 52 to put the scraper assembly 5 in a avoidance state that moves away from the carpet cleaning component 2. Moreover, the floor brush body 3 is provided with a transmission head that is connected to the cleaning component. The floor brush body 3 is provided with a support plate 31 near the transmission head. The support plate 31 is provided with a second protrusion 32 that can cooperate with the second linkage part 53. During the installation of the cleaning component, the second protrusion 32 can be moved to make the second protrusion 32 cooperate with or disengage from the second linkage part 53, thereby driving the scraper assembly 5 to switch between the scraping state and the avoidance state.

[0112] In Method 3, the cooperation between the first protrusion 12 and the first linkage 52, together with the cooperation between the second protrusion 32 and the second linkage 53, can further ensure the reliability of the scraper assembly 5 in randomly switching states during the installation of the cleaning parts. This avoids the phenomenon that the scraper assembly 5 will not switch states in time due to a problem with one of the linkage mechanisms. It not only simplifies the adjustment process, but also makes the overall reliability and stability of the machine stronger.

[0113] As a preferred embodiment of this application, such as Figure 2 , Figure 3 and Figure 5 As shown, the triggering mechanism includes at least two elastic structures 7 symmetrically arranged along the length of the scraper assembly 5, and at least two sets of guide structures symmetrically arranged along the length of the scraper assembly 5. The elastic structures 7 apply a restoring force to the scraper assembly 5, and the guide structures provide movement guidance for the scraper assembly 5 during the switching between the scraping state and the avoidance state. The symmetrical arrangement of the elastic structures 7 helps to provide a balanced restoring force to the scraper assembly 5, thereby facilitating the rapid switching between the scraping state and the avoidance state. The guide structures provide movement guidance and a clear movement path for the scraper assembly 5 during state switching, preventing the scraper assembly 5 from tilting or jamming during movement, or deviating from the predetermined path. This ensures that the scraper assembly 5 maintains the accuracy, smoothness, and consistency of movement during multiple switching processes, thereby ensuring the stability and reliability of the scraper assembly 5's state switching. Furthermore, the symmetrical arrangement of the elastic structures 7 and the guide structures helps to reduce uneven wear of the scraper assembly 5 caused by prolonged use, extending the service life of the scraper assembly 5 and reducing the maintenance cost of the cleaning machine.

[0114] In a specific implementation, such as Figure 5As shown, a plurality of elastic structures 7 and guide structures are provided along the length direction of the scraper assembly 5. Preferably, the elastic structures 7 and guide structures are arranged alternately. Specifically, a water distribution plate 6 is fixedly provided on the front cover 4, and the scraper assembly 5 is movably provided on the water distribution plate 6. The water distribution plate 6 is provided with a plurality of screw holes 62 along its length direction. The guide structure includes screws 8 and guide through holes 54 provided on the scraper assembly 5. The guide through holes 54 are elongated holes so that the scraper assembly 5 can move as a whole along the elongated holes when it moves. The scraper assembly 5 is also provided with a receiving cavity 55 for accommodating the elastic structure 7. The water distribution plate 6 is provided with a mounting position 61 for installing the elastic structure 7. One end of the elastic structure 7 is fixedly connected to the mounting position 61, and the other end abuts against the side wall of the receiving cavity 55 to provide elastic force for the reset of the scraper assembly 5.

[0115] like Figure 12 As shown, this application also discloses a control method for a cleaning machine. The cleaning machine includes a floor brush body 3, a movable scraper assembly 5, cleaning components, and a liquid supply unit. The cleaning components include a floor cleaning component 1 and a carpet cleaning component 2, which are selectively installed on the floor brush body 3. The scraper assembly 5 has a scraping state that abuts against the floor cleaning component 1 and a avoidance state that moves away from the carpet cleaning component 2. The cleaning machine also includes a water circuit control unit. The control method includes:

[0116] Install the cleaning component and trigger the scraper assembly 5 to move to the scraping state or avoidance state during the installation process;

[0117] The water circuit control unit controls the liquid supply unit to supply liquid according to the type of cleaning component to meet the cleaning needs of the surface to be cleaned. When the carpet cleaning component 2 is installed on the floor brush body 3, the liquid supply unit can be controlled to supply liquid to the carpet cleaning component 2 by pressing and holding the handle of the cleaning machine.

[0118] Under this control method, the switching of the cleaning machine scraper assembly 5 position and the selection of the cleaning strategy are both achieved during the installation of the cleaning components. That is, when the carpet cleaning component 2 or the floor cleaning component 1 is installed, the cleaning machine can automatically select the liquid supply strategy, and at the same time, the state of the scraper assembly 5 is also matched. When the cleaning machine is run, it can clean the surface to be cleaned according to the type of cleaning component, the matching state of the scraper assembly 5, and the appropriate cleaning strategy, which greatly improves the cleaning efficiency and the cleaning effect. It also provides corresponding protection for the cleaning component itself and the surface to be cleaned, thus improving user-friendliness.

[0119] In the process where the water circuit control unit controls the liquid supply unit to supply liquid according to the type of cleaning component to meet the cleaning requirements of the surface to be cleaned, the determination of the type of cleaning component includes, but is not limited to, the following implementation methods:

[0120] Method 1: The water circuit control unit includes a first detection element for detecting the state of the scraper assembly 5. Since the state of the scraper assembly 5 matches the type of cleaning component, the type of cleaning component is determined by detecting the state of the scraper assembly 5. The detection of the state of the scraper assembly 5 can, for example, detect the position of the scraping portion 51 or the first linkage portion 52 on the scraper assembly 5. The first detection element can be a micro switch, proximity switch, photoelectric sensor, etc.

[0121] Method 2: The water circuit control unit includes a second detection element. During the installation of the carpet cleaning component 2 or the floor cleaning component 1, the second detection element can be triggered by a triggering mechanism to determine the type of cleaning component. For example, the second detection element is a micro switch, and the triggering mechanism includes a first protrusion 12 provided on the side plate 11 of the carpet cleaning component 2 or the floor cleaning component 1. During the installation of the carpet cleaning component 2 or the floor cleaning component 1, the first protrusion 12 can contact to trigger the micro switch, thereby determining the type of cleaning component based on the detection result of the second detection element.

[0122] Method 3: The water circuit control unit also includes a third detection element located in the brush body 3. The floor cleaning component 1 and / or carpet cleaning component 2 are equipped with a trigger element capable of triggering the third detection element. The water circuit control unit determines the installation status of the cleaning component based on the feedback signal from the third detection element. For example, a magnetic component is provided inside the carpet cleaning component 2, and the third detection element is a Hall sensor located in the brush body 3. When the carpet cleaning component 2 is installed on the brush body 3, the Hall sensor detects the magnetic component, thereby determining that the type of cleaning component is carpet cleaning component 2. The water circuit control unit controls the liquid supply unit to stop supplying liquid to the carpet cleaning component 2, and controls the liquid supply unit to supply liquid to the carpet cleaning component 2 when the switch button on the handle of the cleaning machine is triggered for more than a preset time.

[0123] Example 3:

[0124] This embodiment, based on Embodiment 1, provides a fixed scraper assembly that can simultaneously meet the operational needs of both the carpet cleaning component and the floor cleaning component. In this embodiment, the carpet cleaning component has a smaller outer diameter than the floor cleaning component, ensuring that when the floor cleaning component is mounted on the brush body 3, the scraper assembly 5 at least partially abuts against the floor cleaning component 1, and when the carpet cleaning component 2 is mounted on the brush body 3, the scraper assembly 5 at least partially separates from the carpet cleaning component 2. This satisfies the scraping and cleaning needs of the floor cleaning component 1 by the scraper assembly 5 while reducing abnormal noise during the rotation of the carpet cleaning component 2.

[0125] Furthermore, such as Figure 10 and Figure 11As shown, to reduce the entanglement of filamentous material on the cleaning component, the scraper assembly 5 can be configured to include a scraper 57 and a comb 58. The scraper 57 and comb 58 are arranged along the outer periphery of the cleaning component and extend towards it. For the same cleaning component, the comb 58 is closer to the cleaning component than the scraper 57. When the floor cleaning component 1 is inserted into the floor brush body 3, both the scraper 57 and the comb 58 are interference-fitted with the floor cleaning component 1, with the interference of the scraper 57 being greater than that of the comb 58. When the carpet cleaning component 2 is inserted into the floor brush body 3, the scraper 57 separates from the carpet cleaning component 2, and the comb 58 at least partially abuts against the carpet cleaning component 2, removing filamentous material from the carpet cleaning component 2. Optionally, to reduce abnormal noise during the operation of the cleaning machine, the comb 58 is made of a relatively low-hardness plastic material.
