Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a surface cleaning device and cleaning system. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' quality of life, the cleaning needs of surfaces such as floors and tabletops are becoming increasingly diversified, placing higher demands on the functional integration and cleaning efficiency of cleaning equipment. At present, surface cleaning equipment on the market (such as floor scrubbers and cleaning robots) has gradually evolved from simple mechanical scrubbing to a composite mode of mechanical scrubbing plus liquid assistance, in which hot water and steam are widely used as highly efficient cleaning media.

[0003] In existing technologies, some cleaning equipment is only equipped with a single hot water or steam output function. Equipment with only hot water function typically sprays hot water directly onto cleaning components (such as roller brushes or cloths), achieving cleaning through contact between the components and the surface to be cleaned. However, the hot water temperature drops during the transfer to the cleaning components due to heat loss, especially when cleaning large areas, significantly weakening its ability to dissolve oil stains and stubborn dirt. While equipment with only steam function can utilize the penetrating power of high-temperature steam to break down stains, the steam has a low moisture content, making it difficult to effectively moisten dry, stubborn stains (such as dried food residue), requiring additional water supply and making operation cumbersome.

[0004] Furthermore, in existing equipment, the output of hot water or steam is often connected to the cleaning component. The medium needs to act indirectly on the surface to be cleaned through the cleaning component, which not only aggravates the loss of heat and pressure, but may also reduce the utilization rate of the medium due to the adsorption effect of the cleaning component, thus affecting the cleaning effect.

[0057] This invention provides a cleaning system and a surface cleaning device 100. The cleaning system includes the aforementioned surface cleaning device 100 and a base. The base is used to hold the surface cleaning device 100. In some embodiments, the base can also integrate functions such as charging, liquid replenishment, self-cleaning of the cleaning component 20, and dirt collection. For example, when the surface cleaning device 100 is placed on the base, the base can charge the battery inside the device to ensure its battery life. The base can also be equipped with a water filling structure, which automatically replenishes water to the water tank 41 of the surface cleaning device 100 when it is placed on the base, reducing the need for manual water filling by the user. Thus, the surface cleaning device 100 is responsible for cleaning the surface to be cleaned, while the base provides auxiliary functions such as storage, charging, and / or water replenishment. The combined use of both improves the ease of use and sustainability of the surface cleaning device 100. The surface cleaning device 100 may specifically include a body 200 and a floor brush assembly 300 disposed at the lower end of the body 200. When the user holds and pushes the body 200, the floor brush assembly 300 moves on the surface to be cleaned and performs specific cleaning activities.

[0058] Please see Figures 1 to 5 The surface cleaning device 100 includes a floor brush housing 10, a cleaning component 20, an output assembly, a liquid supply assembly, a heating device 30, and a first valve component 60. The floor brush housing 10 serves as the main structure of the floor brush assembly 300, providing a mounting and support foundation for the other components. Figure 2 and Figure 3 As shown, the cleaning component 20 is disposed on the floor brush housing 10 and is used to directly contact the surface to be cleaned for cleaning purposes. For example, the cleaning component 20 can be a roller brush or a cloth. The output assembly is at least partially disposed within the floor brush housing 10 and includes a first output structure 51 and a second output structure 52. The first output structure 51 is used to spray steam onto the surface to be cleaned and / or the cleaning component 20, and the second output structure 52 is used to spray hot water onto the surface to be cleaned. Please continue reading. Figure 1 The liquid supply assembly supplies water to the cleaning component 20. Specifically, it may include a water tank 41 mounted on the brush housing 10 or the body 200, which can store clean water or cleaning fluid as needed. A heating device 30 is located downstream of the liquid supply assembly and heats the water supplied by the assembly. The heating device 30 can also be mounted on the brush housing 10 or the body 200 as needed. Both the liquid supply assembly and the heating device 30 are located upstream of the output assembly to supply hot water and / or steam to the output assembly as needed. Optionally, the first output structure 51 includes a spray plate 512, mounted on the brush housing and located in front of the cleaning component 20. This spray plate 512 guides the steam more evenly to the surface to be cleaned. Through the cooperation of the spray plate 512 and the cleaning component 20, the dirt is first dissolved and softened by the steam over a large area, and then thoroughly cleaned through the friction between the cleaning component 20 and the surface to be cleaned.

[0059] The heating device 30 can be a boiler including electric heating elements or heating plates, etc. The heating device 30 can heat water to the required temperature using electrical energy to provide hot water. By adjusting the heating temperature, steam can also be generated when the water vaporizes to supply steam.

[0060] The first valve component 60 is disposed between the heating device 30 and the output component in the liquid supply direction, and the output end of the valve component 60 can be selectively connected to either the first output structure 51 or the second output structure 52. It should be noted that, in this invention, the liquid supply direction refers to the direction in which liquid flows from the liquid supply component to the terminal cleaning component 20 and / or the output structure, and the liquid flows from upstream to downstream. Figure 1 As shown in the figure, the direction of the arrow represents the direction of liquid supply.

[0061] Please continue reading. Figure 1 Specifically, the first valve component 60 has a first valve inlet 61, a first valve outlet 62, and a second valve outlet 63. The first valve inlet 61 is connected to the outlet end of the heating device 30, the first valve outlet 62 is connected to the first output structure 51, and the second valve outlet 63 is connected to the second output structure 52. In practical applications, the liquid supply assembly can be a structure composed of a water tank 41 and a pump body. The pump body pumps the liquid in the water tank 41 and delivers it to the heating device 30. The first valve component 60 can be a three-way solenoid valve. By controlling the valve core of the solenoid valve, the state switching can be achieved: the first valve inlet 61 is connected to the first valve outlet 62 while the second valve outlet 63 is closed, or the first valve inlet 61 is connected to the second valve outlet 63 while the first valve outlet 62 is closed.

[0062] In this embodiment, the liquid supply assembly supplies water to the heating device 30, which heats the water. The heated water then enters the first valve inlet 61 of the first valve component 60. At this time, by controlling the first valve component 60, the heated water or steam can selectively flow from the first valve outlet 62 to the first output structure 51, from which steam is sprayed onto the surface to be cleaned and / or the cleaning component 20. Alternatively, it can flow from the second valve outlet 63 to the second output structure 52, from which hot water is sprayed onto the surface to be cleaned.

[0063] This embodiment directly sprays hot water onto the surface to be cleaned through the first output structure 51 and the second output structure 52, avoiding heat loss and pressure attenuation caused by indirect hot water transfer via the cleaning component 20 in existing technologies, thus improving the cleaning effect on stubborn stains. Simultaneously, the same heating device 30 and the first valve component 60 enable switching between steam and hot water output, eliminating the need for separate heating and control structures for each, simplifying the structure of the surface cleaning device 100 and reducing costs. Finally, the first valve component 60 allows for flexible switching between steam and hot water output, enabling users to quickly adjust according to the type of stain to meet diverse cleaning needs. High-temperature steam can directly decompose stubborn stains, while hot water can directly rinse away stains; the combination of both significantly enhances the cleaning effect. This improves the operational reliability and cleaning efficiency of the surface cleaning device 100.

[0064] Based on the above embodiments, such as Figure 1 As shown, the surface cleaning device 100 also includes a liquid outlet 80, which is disposed on the floor brush housing 10 and sprays water onto the cleaning component 20. Specifically, it can be configured as a water distributor. The liquid supply assembly includes a water tank 41, a first pump body 42, and a second valve component 70. The inlet end of the first pump body 42 is connected to the water tank 41, and the outlet end of the first pump body 42 is connected to the second valve component 70. The output end of the second valve component 70 can be selectively connected to the liquid outlet 80 or the heating device 30.

[0065] Preferably, the second valve component 70 has a second valve inlet 71, a third valve outlet 72, and a fourth valve outlet 73. The second valve inlet 71 is connected to the liquid outlet end of the first pump body 42, the third valve outlet 72 is connected to the liquid outlet component 80, and the fourth valve outlet 73 is connected to the upstream of the heating device 30.

[0066] Based on the structure of the surface cleaning device 100 described above, the surface cleaning device 100 has a conventional cleaning mode and a hot water cleaning mode. In the conventional cleaning mode, the second valve component 70 connects the water tank 41 and the liquid outlet 80. Specifically, the first pump body 42 operates, the second valve inlet 71 is open, the third valve outlet 72 is open, and the fourth valve outlet 73 is closed. In the hot water cleaning mode, the second valve component 70 connects the water tank 41 and the heating device 30. Specifically, the second valve inlet 71 is open, the third valve outlet 72 is closed, and the fourth valve outlet 73 is open. The liquid outlet 80 can be a spray head or a water distributor installed on the floor brush housing 10, which faces the cleaning component 20 and can spray water evenly onto the cleaning component 20. The first pump body 42 provides power for the delivery of water, and the second valve component 70 can be a three-way solenoid valve. By controlling the movement of its valve core, the opening and closing of the third valve outlet 72 and the fourth valve outlet 73 can be realized.

[0067] Specifically, in the normal cleaning mode, the first pump body 42 draws water from the water tank 41. The water enters the second valve inlet 71 of the second valve component 70 through the outlet of the first pump body 42. Since the third valve outlet 72 is open and the fourth valve outlet 73 is closed, the water flows from the third valve outlet 72 to the outlet component 80. The outlet component 80 sprays the water onto the cleaning component 20, which cleans the surface to be cleaned in a wet state. The water sprayed onto the cleaning component 20 is not heated. In the hot water cleaning mode, the first pump body 42 operates. After the water enters the second valve component 70 through the second valve inlet 71, since the third valve outlet 72 is closed and the fourth valve outlet 73 is open, the water flows from the fourth valve outlet 73 to the heating device 30. After being heated by the heating device 30, it becomes hot water. Then, under the control of the first valve component 60, the second output structure 52 sprays the hot water onto the surface to be cleaned, working in conjunction with the cleaning component 20 for cleaning.

[0068] In this embodiment, by setting up a liquid outlet 80 and a second valve component 70, the switching between a conventional cleaning mode and a hot water cleaning mode is realized. In the conventional cleaning mode, water is supplied to the cleaning component 20 to meet daily light cleaning needs, while in the hot water cleaning mode, hot water is supplied to the surface to be cleaned to enhance the cleaning effect. Furthermore, the switching between the two modes can be achieved through the control of the same liquid supply component and the second valve component 70, resulting in a compact structure, convenient operation, and improved applicability of the equipment.

[0069] For further information, please refer to [link / reference]. Figure 1 , Figure 4 and Figure 5 The liquid supply assembly also includes a second pump body 43, which is connected to the water tank 41 and the heating device. In hot water cleaning mode, the liquid flows to the heating device via the second pump body 43. Thus, hot water and room temperature water are supplied through different pump bodies to meet actual cleaning needs.

[0070] Preferably, the liquid supply assembly further includes a first connecting component 44, which is connected to the second pump body 43, the second valve component 70, and the heating device 30, respectively. The rated flow rate of the second pump body 43 is less than that of the first pump body 42. Specifically, the first connecting component 44 has a first inlet 441, a second inlet 442, and a first outlet 443. The inlet end of the second pump body 43 is connected to the water tank 41, the outlet end of the second pump body 43 is connected to the first inlet 441 of the first connecting component 44, the fourth valve outlet 73 is connected to the second inlet 442, and the first outlet 443 is connected to the inlet end of the heating device 30.

[0071] Furthermore, such as Figure 1 As shown, the first pump body 42 and the second pump body 43 are connected to the water tank 41 via a second three-way valve 45. The second three-way valve 45 has a third inlet 451, a second outlet 452, and a third outlet. The third inlet 451 is connected to the water tank 41, the second outlet 452 is connected to the second pump body 43, and the third outlet is connected to the first pump body 42, thus enabling the same water tank 41 to simultaneously supply liquid to both the first pump body 42 and the second pump body 43. When the first pump body 42 is working, the second valve component 70 can be controlled to directly supply cold water to the liquid outlet 80 or to achieve a hot water cleaning mode. When the second pump body 43 is working, a steam cleaning mode can be achieved. It can be understood that the first pump body 42 and the second pump body 43 can also work simultaneously.

[0072] The surface cleaning device 100 also features a steam cleaning mode. In this mode, the second pump 43 operates, the second valve inlet 71 is closed, or the second valve inlet 71 is open, the third valve outlet 72 is open, and the fourth valve outlet 73 is closed. Here, the rated flow rate of the second pump 43 is relatively small, suitable for providing a small, continuous flow of water to the steam-generating heating device 30. The first connecting component 44 can be a pipe connector with three ports, used to collect water from different paths and deliver it to the same outlet.

[0073] In this embodiment, in steam cleaning mode, when the second valve inlet 71 is closed, the second pump body 43 draws water from the water tank 41. The water enters the first inlet 441 of the first connecting component 44 through the outlet of the second pump body 43. Since the second inlet 442 of the first connecting component 44 is connected to the fourth valve outlet 73, and the fourth valve outlet 73 is closed at this time, the water flows to the heating device 30 only through the first outlet 443 of the first connecting component 44. The heating device 30 heats a small amount of water to vaporize it into steam. The steam is sprayed onto the cleaning component 20 and / or the surface to be cleaned by the first output structure 51 under the control of the first valve component 60. When the second valve inlet 71 is open, the third valve outlet 72 is open, and the fourth valve outlet 73 is closed, the first pump body 42 works to deliver water to the outlet component 80 and spray it onto the cleaning component 20. At the same time, the second pump body 43 works to deliver water to the heating device 30 through the first connecting component 44 to generate steam, realizing the combination of steam cleaning and moist cleaning of the cleaning component 20.

[0074] This embodiment, by setting a second pump body 43 with a smaller rated flow rate, can provide an appropriate amount of water for steam generation, ensuring the stability of steam output. The addition of a steam cleaning mode further enriches the equipment's cleaning functions, enabling it to handle more types of stubborn stains and improving its cleaning ability and applicability.

[0075] Based on the above embodiments, please refer to the following: Figure 1 and Figure 5 The first output structure 51 includes a water vapor separation device 511 and a spray plate 512. The water vapor separation device 511 has an inlet 501, a water vapor outlet 502 and a liquid outlet 503. The inlet 501 is connected to the first valve outlet 62, the water vapor outlet 502 is connected to the spray plate 512, and the liquid outlet 503 is used to guide the water liquid to the cleaning component 20.

[0076] In this embodiment, the water vapor separator 511 is a device for separating water and steam. It may have internal baffles or filters to allow steam in the water vapor mixture entering from the inlet 501 to exit from the water vapor outlet 502, while unvaporized water flows out from the liquid outlet 503. The spray plate 512 preferably has multiple small nozzles, allowing steam to be evenly sprayed onto the surface to be cleaned. In this embodiment, the water vapor mixture formed after heating by the heating device 30 enters the inlet 501 of the water vapor separator 511 through the first valve outlet 62. Inside the water vapor separator 511, steam flows through the water vapor outlet 502 to the spray plate 512, and is then sprayed onto the surface to be cleaned. Unvaporized water flows out from the liquid outlet 503 and is guided to the cleaning component 20, where the cleaning agent absorbs excess water while keeping the cleaning component 20 moist.

[0077] In this way, the steam and water in the water-vapor mixture are separated by the water-vapor separation device 511, making the steam sprayed by the spray plate 512 purer and improving the steam cleaning effect. At the same time, the separated water can be used to wet the cleaning parts 20, realizing the rational use of resources and enhancing the overall cleaning effect.

[0078] Based on the previous embodiment, preferably, the surface cleaning device 100 further includes a driving device and a negative pressure device. The cleaning component 20 is rotatably mounted on the floor brush housing 10. The driving device is driven by the cleaning component 20 to drive the cleaning component 20 to rotate. The floor brush housing 10 has a suction port near the cleaning component 20, and the suction port is connected to the negative pressure device. The surface cleaning device 100 also has a self-cleaning mode. In the self-cleaning mode, the driving device and the negative pressure device work, the liquid supply component supplies water to the cleaning component 80, and the heating device 30 heats the water supplied by the liquid supply component. Specifically, this is achieved by controlling the first valve component 60 and the second valve component 70. That is, in the self-cleaning mode, the second valve inlet 71 is open, the third valve outlet 72 is closed, the fourth valve outlet 73 is open, the first valve inlet 61 is open, the first valve outlet 62 is open, and the second valve outlet 63 is closed.

[0079] In this embodiment, the driving device can specifically be a motor, which can be connected to the cleaning component 20 via gear or belt drive to drive the cleaning component 20 to contact the coal during operation. The negative pressure device can include a fan structure, which generates negative pressure to create suction at the suction port, drawing sewage and debris into the sewage tank 41 for storage. In self-cleaning mode, the driving device drives the cleaning component 20 to rotate, while the negative pressure device works to generate suction at the suction port. The first pump body 42 delivers water to the heating device 30 through the fourth valve outlet 73 of the second valve component 70. The heated water-vapor mixture enters the water-vapor separator 511 through the first valve outlet 62 of the first valve component 60. Steam is sprayed from the spray plate 512 and may act on the cleaning component 20. The separated water is also guided to the cleaning component 20 to clean it, while the sewage generated during cleaning is drawn into the suction port and discharged through the negative pressure device.

[0080] In self-cleaning mode, the cleaning component 20 can be automatically cleaned without the need for the user to manually disassemble it for cleaning, reducing the user's operational burden. At the same time, the combination of the drive device, negative pressure device, water and steam can effectively remove stains from the cleaning component 20, ensuring the cleanliness of the cleaning component 20 and thus ensuring the effectiveness of subsequent cleaning work.

[0081] In an alternative embodiment, such as Figures 3 to 5As shown, the floor brush housing 10 includes an upper housing 11 and a lower housing 12 arranged sequentially from top to bottom. The cleaning component 20 is installed in the lower housing 12. An installation cavity 13 is formed between the upper housing 11 and the lower housing 12. A water vapor separation device 511 is installed in the installation cavity 13 and located above the cleaning component 20. A liquid guiding channel is formed in the lower housing 12, which communicates with the liquid outlet 503 and faces the cleaning component 20.

[0082] In this embodiment, the upper housing 11 and the lower housing 12 are detachably connected, specifically by means of clips or screws, forming the overall structure of the floor brush housing 10. The mounting cavity 13 provides installation space for the internal components and protects them from external damage. The liquid guiding channel is a groove or pipe structure opened in the lower housing 12, used to guide the water flowing out of the liquid outlet 503 to the cleaning component 20. Thus, the water vapor separator 511 is installed in the mounting cavity 13 formed by the upper housing 11 and the lower housing 12, and is located above the cleaning component 20. The water flowing out of the liquid outlet 503 of the water vapor separator 511 enters the liquid guiding channel on the lower housing 12, and is guided by the liquid guiding channel to flow accurately to the cleaning component 20, wetting or cleaning the cleaning component 20. The mounting cavity 13 provides a stable installation position for the water vapor separator 511, protecting it from external impacts. The liquid guiding channel ensures that the water flowing out of the liquid outlet 503 accurately reaches the cleaning component 20, preventing the water from flowing randomly and causing damage to other internal components of the equipment, while also improving the utilization rate of the water.

[0083] Further, please refer to Figure 3 and Figure 5 The spray plate 512 is mounted on the lower housing 12 and located in front of the cleaning component 20. The steam outlet 502 is connected to the spray plate 512 through a second pipe 15 disposed in the mounting cavity 13. The second pipe 15 can be a flexible or rigid pipe, used to transport the steam discharged from the steam outlet 502 to the spray plate 512. The spray plate 512 is located in front of the cleaning component 20, so that the steam is sprayed onto the surface to be cleaned first, pre-treating the stains and facilitating the subsequent cleaning of the cleaning component 20.

[0084] In this embodiment, the steam separated by the water vapor separator 511 flows out from the water vapor outlet 502 and is transported through the second pipeline 15 in the mounting cavity 13 to the spray plate 512 installed in the lower housing 12 and located in front of the cleaning component 20. The spray plate 512 sprays steam onto the area in front of the surface to be cleaned, softening and decomposing the stains in the area. Then the cleaning component 20 cleans the area that has been pretreated by steam.

[0085] Based on the above embodiments, the first valve component 60 has a first operating state and a second operating state. In the first operating state, the first valve inlet 61 and the first valve outlet 62 are open, while the second valve outlet 63 is closed. In the second operating state, the first valve inlet 61 and the second valve outlet 63 are open, while the first valve outlet 62 is closed. The surface cleaning device 100 also includes a switch, which, in hot water cleaning mode, controls the first valve component 60 to switch between the first operating state and the second operating state. Figure 2 As shown, the switching switch is preferably located on the handle of the body 200. Its specific form can be a button or a knob. The user sends a control signal to the first valve component 60 by operating the switching switch. The working state switching of the first valve component 60 is usually achieved by the movement of its internal valve core. The movement of the valve core changes the connection state between the interfaces.

[0086] In the hot water cleaning mode, when the user operates the switch to put the first valve component 60 into the first working state, the first valve inlet 61 and the first valve outlet 62 are connected, and steam is sprayed onto the surface to be cleaned and / or the cleaning component 20 through the first output structure 51. When the user operates the switch to put the first valve component 60 into the second working state, the first valve inlet 61 and the second valve outlet 63 are connected, and heated hot water is sprayed onto the surface to be cleaned through the second output structure 52. In this embodiment, the switch allows the user to flexibly switch between steam and hot water output in the hot water cleaning mode according to the degree of dirt on the surface to be cleaned. The operation is simple and convenient, improving the flexibility and targeted cleaning of the equipment.

[0087] The second output structure 52 can have various specific structures, as long as it can directly face the surface to be cleaned. In one embodiment, such as... Figures 3 to 5 As shown, the second output structure 52 includes a nozzle 521 disposed on the floor brush housing 10, with the nozzle 521 positioned facing forward of the floor brush housing 10. The nozzle 521 can be a structure with a certain spray angle, capable of spraying hot water onto the surface to be cleaned in front of the floor brush housing 10 within a suitable range. Positioning it forward allows the hot water to pre-wash away stains in front, facilitating subsequent cleaning by the cleaning components 20. Simultaneously, the user can visually determine which area the hot water can be sprayed on during cleaning, enabling more targeted and precise hot water spraying treatment of stains.

[0088] Based on the previous embodiment, please continue to refer to... Figures 3 to 5The floor brush housing 10 includes an upper housing 11 and a lower housing 12 arranged sequentially from top to bottom. The cleaning component 20 is installed in the lower housing 12. An installation cavity 13 is formed between the upper housing 11 and the lower housing 12. The nozzle 521 is located at the front end of the floor brush housing 10 and is connected to the second valve outlet 63 through a first pipe 14 located in the installation cavity 13. The first pipe 14 is similar to the second pipe 15 and is a pipe for transporting hot water. It can be a flexible or rigid pipe. The first pipe 14 is located in the installation cavity 13, which can be protected by the floor brush housing 10 and make the equipment structure more compact. The nozzle 521 is located at the front end of the floor brush housing 10, which can spray hot water more directly onto the area in front of the surface to be cleaned.

[0089] In this embodiment, heated hot water flows out from the second valve outlet 63 and is transported through the first pipe 14 installed in the mounting cavity 13 of the floor brush housing 10 to the nozzle 521 located at the front end of the floor brush housing 10. The nozzle 521 sprays hot water onto the surface to be cleaned in front of the floor brush housing 10 to rinse away the stains. Then the cleaning component 20 further cleans the area.

[0090] In one embodiment, a surface cleaning device 100 includes a floor brush housing 10, a cleaning component 20, a first output structure 51, a liquid supply assembly, a heating device 30, and a second valve component 70. The cleaning component 20 is disposed within the floor brush housing 10 and is used to directly contact the surface to be cleaned to achieve cleaning. The first output structure 51 is at least partially disposed within the floor brush housing 10 and includes a water vapor separator 511 and a spray plate 512. The water vapor separator 511 has an inlet 501, a water vapor outlet 502, and a liquid outlet 503. Its inlet 501 is connected to the liquid outlet of the heating device 30, and its water vapor outlet 502 is connected to the spray plate 512 to uniformly spray steam onto the surface to be cleaned. The liquid supply assembly is used to supply water to the cleaning component 20 and the first output structure 51, and may include a water tank 41. The heating device 30 is located downstream of the liquid supply component and can heat the water supplied by the liquid supply component to above 100°C, causing the water to partially vaporize and form a water-vapor mixture. The outlet end of the heating device 30 is connected to the inlet 501 of the water-vapor separator 511.

[0091] The second valve component 70 is disposed between the liquid supply assembly, the cleaning component 20, and the heating device 30. Its input end is connected to the liquid outlet of the liquid supply assembly, and its output end can be selectively connected to the liquid outlet 80 supplied by the cleaning component 20 or the liquid inlet of the heating device 30. By controlling the movement of the valve core inside the second valve component 70, selective connection between it and the cleaning component 20 or the heating device 30 can be achieved.

[0092] In this embodiment, when routine cleaning is required, the second valve component 70 switches to a state connected to the cleaning component 20. The water from the supply component is delivered to the outlet component 80 via the second valve component 70. The outlet component 80 evenly sprays the water onto the cleaning component 20 and / or the area to be cleaned near the cleaning component 20. The cleaning component 20 rotates under the drive of the drive device, and the friction between the wet cleaning component 20 and the surface to be cleaned achieves the removal of dirt. When steam cleaning is required, the second valve component 70 switches to a state connected to the heating device 30. The water from the supply component is delivered to the heating device 30. The heating device 30 is energized and heats the water to form a water-vapor mixture. After the water-vapor mixture enters the water-vapor separator 511, the steam flows through the water-vapor outlet 502 to the spray plate 512 and is sprayed onto the surface to be cleaned, softening the stains. At the same time, the separated water is separated from the liquid to improve the purity of the steam and avoid water stains.

[0093] In one embodiment, the surface cleaning device 100 includes a floor brush housing 10, a cleaning component 20, an output component, a liquid supply component, a heating device 30, and a lifting scraper 90. The cleaning component 20 is disposed within the floor brush housing 10 and is used to directly contact the surface to be cleaned. The output component is at least partially disposed within the floor brush housing 10 and is used to spray steam toward the surface to be cleaned in front of the cleaning component 20. Specifically, it may include a spray plate 512 connected to the liquid outlet of the heating device 30. The spray plate 512 is installed in the lower housing 12 of the floor brush housing 10 and located directly in front of the cleaning component 20, ensuring that the steam can be directed onto the area in front of the cleaning component 20 to be cleaned. The liquid supply component supplies water to the cleaning component 20 and the output component. The heating device 30 is located downstream of the liquid supply component and can heat the water supplied by the liquid supply component to above 100°C, causing the water to vaporize and form steam. The liquid outlet of the heating device 30 is connected to the spray plate 512 of the output component to ensure stable steam delivery.

[0094] The lifting scraper 90 is disposed on the floor brush housing 10 and located in front of the cleaning component 20, and has a pressed-down position and a raised position through mechanical structure design. In this embodiment, the lifting scraper 90 is a strip-shaped structure whose position can be adjusted along the direction perpendicular to the surface to be cleaned. It can be made of elastic material such as silicone. Preferably, the lifting scraper 90 extends along the width direction of the floor brush housing 10, and its function is to control the steam action area according to the movement direction of the equipment. Specifically, when the lifting scraper 90 is in the pressed-down position, its lower end face is in contact with the surface to be cleaned; when the lifting scraper 90 is in the raised-down position, its lower end face is detached from the surface to be cleaned.

[0095] The surface cleaning device 100 can detect the direction of movement. When the output component sprays steam, the lifting scraper 90 is in the raised position when the surface cleaning device 100 moves forward and in the depressed position when it moves backward. Thus, when the surface cleaning device 100 is performing steam cleaning, the steam is sprayed towards the surface to be cleaned in front of the cleaning component 20. When the user pushes the floor brush housing 10 forward, the lifting scraper 90 remains in the raised position, allowing steam to diffuse over a large area in front, quickly softening stains. The cleaning component 20 then scrubs the softened stains as the device moves. When the user pulls the floor brush housing 10 backward, the lifting scraper 90 switches to the depressed position, reducing steam loss. In this way, the large-area steam coverage when the surface cleaning device 100 moves forward improves cleaning efficiency, while the concentrated steam action when it moves backward enhances the ability to clean stubborn stains, catering to the needs of different cleaning scenarios.

[0096] Preferably, when the lifting scraper 90 is in the depressed position, the lifting scraper 90, the floor brush housing 10, and the cleaning component 20 enclose and define a steam retention area. Specifically, the front boundary of this area is the lifting scraper 90 in the depressed position, the side boundaries are the baffles of the floor brush housing 10 distributed on both sides of the cleaning component 20, the rear boundary is the front end face of the cleaning component 20, and the lower boundary is the surface to be cleaned. In this way, the lifting scraper 90, the floor brush housing 10, and the cleaning component 20 cooperate to form a relatively enclosed space, in which the output component spray plate 512 can be placed. In this embodiment, the steam retention area can prolong the contact time between steam and stains, improving the effect of steam softening stubborn stains.

[0097] In one embodiment, the surface cleaning device 100 can achieve a self-cleaning function when placed on the base. In this embodiment, a cleaning groove is provided on the base. The cleaning groove is a recessed structure formed by the base, and its shape is adapted to the bottom shape of the floor brush housing 10 to ensure that when the surface cleaning device 100 is placed on the base, the cleaning component 20 on the floor brush housing 10 can at least partially extend into the cleaning groove and can be placed stably.

[0098] The surface cleaning device 100 includes a floor brush housing 10, a cleaning component 20, an output assembly, a drive unit, a negative pressure device, a first pump body 42, a water tank 41, and a heating device 30. The cleaning component 20 is disposed at the bottom of the floor brush housing 10, and can specifically be a roller brush rotatably mounted on the floor brush housing 10. The output assembly is at least partially embedded inside the floor brush housing 10, and its specific structure can be referred to the above embodiment. The function of the output assembly is to output hot water into the cleaning tank, and it is connected to the heating device 30. The drive unit includes a motor, and the output shaft of the motor is connected to the transmission of the cleaning component 20, which can drive the cleaning component 20 to rotate around its own axis. The negative pressure device can specifically be configured as a fan. The bottom of the floor brush housing 10 has a suction port near the cleaning component 20, which is connected to the air inlet of the negative pressure device. The air outlet of the negative pressure device is connected to the wastewater tank 41 for collecting the sucked-in wastewater and debris.

[0099] The first pump body 42, the water tank 41, and the heating device 30 together constitute the liquid supply assembly. The inlet of the first pump body 42 is connected to the outlet of the water tank 41, and the output of the first pump body 42 can be selectively connected to the heating device 30 or the cleaning component 20. In self-cleaning mode, the cleaning component 20 is at least partially located in the cleaning tank, the drive device and the negative pressure device are working, and the first pump body 42 is connected to the heating device 30, thereby outputting hot water to the cleaning tank through the output assembly.

[0100] Preferably, the first pump body 42 is connected to the heating device 30 or the liquid outlet 80 via the second valve component 70. Specifically, the second valve component 70 can be an electromagnetically controlled three-way valve, having a second valve inlet 71, a third valve outlet 72, and a fourth valve outlet 73. The second valve inlet 71 is connected to the liquid outlet end of the first pump body 42 via a pipeline, the third valve outlet 72 is connected to the liquid outlet 80, which is a cold water supply component facing the cleaning component 20, and the fourth valve outlet 73 is connected to the liquid inlet end of the heating device 30 via a pipeline. When the heating device 30 is energized, it heats the flowing water, and its liquid outlet end is connected to the output component via a pipeline, thereby delivering the hot water to a liquid supply component such as the nozzle 521 and / or a water vapor separator.

[0101] When the surface cleaning device 100 needs to be self-cleaned, it is placed on the base. The cleaning component 20, with the assistance of the positioning structure, is at least partially located in the cleaning tank. Upon activation of the self-cleaning mode, the first pump 42 starts, drawing water from the water tank 41. Simultaneously, the second valve component 70, under the control signal, switches to a state where the second valve inlet 71 is open, the third valve outlet 72 is closed, and the fourth valve outlet 73 is open, thus creating a passage to the heating device 30. Water flows into the heating device 30 through the fourth valve outlet 73, heating it to a preset temperature to form hot water. The hot water is then sprayed directly onto the cleaning component 20 or into the cleaning tank through the output component, allowing the cleaning component 20 to come into contact with the hot water. After contact with the surface of the cleaning component 20, the hot water quickly dissolves stubborn stains such as oil and dried food residue. Simultaneously, the drive device and negative pressure device are powered on, and the drive device drives the cleaning component 20 to rotate around its own axis, continuously carrying away the stains. A negative pressure device, such as a fan rotating at high speed, generates negative pressure, creating suction at the suction port, and the wastewater and impurities generated during the cleaning process are sucked into the wastewater tank 41.

[0102] In this cleaning system, the liquid supply components (water tank 41, first pump body 42), recovery components (sewage tank 41), and heating components (heating device 30) for cleaning the cleaning parts 20 are all integrated into the surface cleaning equipment 100 itself. The base only needs to be equipped with a cleaning tank to accommodate the cleaning parts 20 and collect the sewage, eliminating the need for separate hardware such as a liquid supply pump, heating module, and liquid storage container for cleaning the cleaning parts 20. This not only saves on high-cost functional components in the base but also eliminates the need for complex piping installation structures in the base, simplifying the mold development and assembly process of the base. Furthermore, it reduces the subsequent maintenance costs and difficulty of the base, improving the user experience.

[0103] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
