[0034] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so as to fully understand how the present invention uses technical means to solve technical problems and achieve technical effects and to implement it accordingly.

[0035] The term "comprising" as used in the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to". The terms "coupled" or "electrically connected" herein include any direct and indirect electrical coupling means. Therefore, if a first device is described as coupled to a second device, it means that the first device can be directly electrically coupled to the second device, or indirectly electrically coupled to the second device through other devices or coupling means. The following descriptions in the specification are preferred embodiments for carrying out the invention; however, these descriptions are for the purpose of illustrating the general principles of the invention and are not intended to limit the scope of the invention. The scope of protection of this invention is determined by the appended claims.

[0036] The surfaces to be cleaned in this application include ceramic floors, wooden floors, carpets, crevices and corners, kitchen countertop stains, the area around kitchen range hoods, dirt and mold in bathroom corners, children's toys, clothes and wardrobes that have been stored for a long time, sofas and mattresses, etc. The stains to be treated include dust, sewage, water stains, mud stains, oil stains, food, seasonings, etc. The applicable environments include homes, restaurants, outdoor environments, or environments with disinfection requirements. Specific Implementation

[0038] The following is for reference. Figure 1-11 A cleaning device according to an embodiment of the present invention is described.

[0039] refer to Figure 1 The cleaning equipment includes a body 1 and a floor brush assembly 5.

[0040] Specifically, the body 1 includes a top-mounted handle that a user can hold to guide the floor brush assembly 5 to move on the surface to be cleaned. The end of the body 1 away from the handle is rotatably connected to the floor brush assembly 5. The body 1 can rotate about at least two mutually orthogonal axes of the floor brush assembly 5. In one embodiment, the body 1 also has a rotational degree of freedom relative to the floor brush assembly 5.

[0041] The floor brush assembly 5 includes a roller brush receiving cavity. The roller brush 51 is removably arranged within this cavity and driven by a roller brush motor. The roller brush 51 contacts the surface to be cleaned to agitate and sweep away dirt, transferring it into the collection channel 53 of the floor brush assembly 5. The floor brush assembly 5 also includes a distributor 52, comprising nozzles 521 for dispensing cleaning fluid. These nozzles 521 face the surface to be cleaned and / or the surface of the roller brush 51. The cleaning effect is enhanced by the combined action of the cleaning fluid and the agitation of the roller brush. It is worth noting that the cleaning fluid includes, but is not limited to, water, concentrated cleaning agents, disinfectants, mixtures of the above solutions, and steam.

[0042] In some embodiments, a recycling bin assembly 4 is removably disposed on the body 1 or the floor brush assembly 5. The recycling bin assembly 4 includes a recycling bin 41 and a suction source 42. The inlet at the bottom of the recycling bin 41 is connected to a recycling pipe on the body 1 or the floor brush assembly 5, and further connected to a recycling channel 53. The suction source 42 is an actuator such as a fan that can generate a suction effect. At least one filter mechanism is disposed in the fluid pipe between the suction source 42 and the recycling bin 41 to filter out solid and liquid impurities in the fluid sucked in by the suction source 42 from the recycling bin 41. The recycling bin 41 is disposed with at least one separation mechanism 43 that can separate liquid and gas in the recycled dirt.

[0043] Optionally, the recycling bin 41 is also equipped with a detection element (not shown in the figure) that automatically seals the air outlet or stops the suction source when the liquid level in the recycling bin reaches a predetermined position. The detection element is of the type of float switch or resistive sensor. The recycling channel in the floor brush assembly 5 has suction force based on the suction source 42 to suck sewage and solid waste into the recycling bin 41.

[0044] In some application scenarios of the present invention, dirt such as dust, mud, hair, and solid particles on the surface to be cleaned are agitated by the roller brush 51 and sucked into the recycling bin 41 through the recycling channel. The recycling bin separates and collects the dirt, and the separated air is filtered by the filter mechanism in the fluid pipeline and discharged from the exhaust port of the suction source 42.

[0045] Combination Figure 1 ,by Figure 2 Taking the orientation as an example, the cleaning device of the present invention also includes a solution module 3, which includes a solution tank 31. The solution tank 31 is removably disposed on the mounting position at the lower part of the body 1. After the solution module 3 is installed on the cleaning device, the output end at the bottom of the solution tank 31 is connected to the first inlet connector 11 on the mounting position. The first inlet connector 11 is in fluid communication with the distributor 52. Thus, the water or solution in the solution tank 31 can be sprayed from the nozzle 521 of the distributor 52 to the roller brush 51 and / or the surface to be cleaned through the first inlet connector 11 by a pump or by its own weight.

[0046] Optionally, the solution tank 31 is also equipped with a liquid level detection element to detect whether the water tank is short of water. The liquid level detection element is of the type of float switch, capacitive proximity switch, pressure sensor or photoelectric sensor, etc. The detection element is coupled to the control system to display and / or indicate the status of the water tank.

[0047] The cleaning device of the present invention further includes a steam module 2, which comprises a supply tank for storing cleaning solution and a steam generator, the supply tank being connected to the steam generator. The steam module 2 and the solution module 3 are alternatively configured on the cleaning device. Figure 1-2 ,by Figure 3 Taking the orientation as an example, the steam module 2 is removably configured on the mounting position on the upper part of the body 1. When the steam module 2 is configured on the cleaning equipment, its bottom output end is connected to the first inlet connector 11 (not shown in the figure) on the mounting position, so that the steam generated by the steam module 3 is sprayed from the nozzle 521 of the distributor 52 to the roller brush 51 and / or the surface to be cleaned through the first inlet connector 11.

[0048] It is worth noting that when the steam module 2 is configured on the cleaning equipment, it can not only distribute steam to the roller brush 51 and / or the surface to be cleaned, but also distribute solution to the roller brush 51 and / or the surface to be cleaned as needed. Specifically, the brake switch of the steam generator is automatically or manually controlled to control the operation of the steam generator. When the steam generator is working, the solution in the solution tank generates steam through the steam module 2, and the steam is guided to the distributor. When the steam generator stops working, the solution in the solution tank only passes through the steam generator without being converted into steam, and is then guided to the distributor.

[0049] The cleaning equipment of this invention can be configured with different modules for different usage scenarios to switch to different working modes, thereby enriching the usage environment and functions of the cleaning equipment and achieving multi-purpose functionality. The working modes that the cleaning equipment can switch to include at least the following types:

[0050] Dry cleaning. The cleaning equipment is not equipped with steam module 2 and solution module 3. During operation, the main control unit controls the roller brush motor (not shown in the figure) and suction source 42 to start. The roller brush motor drives the roller brush 51 to agitate the stains on the surface to be cleaned, so as to remove the stains from the surface to be cleaned and sweep them into the floor brush assembly 5. At the same time, the suction source 42 generates suction on the recovery channel 53 to guide the stains to the recovery bin 41 for collection.

[0051] In wet cleaning, solution module 3 is installed on the cleaning equipment. During operation, the main control unit controls the roller brush motor (not shown) and suction source 42 to start. The roller brush motor drives the roller brush 51 to agitate the dirt on the surface to be cleaned, removing the dirt from the surface and sweeping it into the floor brush assembly 5. At the same time, suction source 42 generates suction on the recovery channel 53 to guide the dirt to the recovery bin 41 for collection. During this process, the solution in solution module 3 flows from the first inlet connector 11 to the distributor 52 through a pump or by its own weight to distribute the cleaning solution to the roller brush 51 or the surface to be cleaned. In this working mode, the roller brush, in conjunction with the cleaning solution, more effectively removes dirt, improving the cleaning effect.

[0052] Steam cleaning involves replacing the solution module 3 with a steam module 2 on the cleaning equipment. During operation, the main control unit controls the roller brush motor (not shown in the figure) and the suction source 42 to start. The roller brush motor drives the roller brush 51 to agitate the stains on the surface to be cleaned, removing the stains from the surface and sweeping them into the floor brush assembly 5. At the same time, the suction source 42 generates suction on the recovery channel 53 to guide the stains to the recovery bin 41 for collection. During this process, the steam generated by the steam module 2 flows from the first inlet connector 11 to the distributor 52 to distribute hot steam to the roller brush 51 or the surface to be cleaned, accelerating the softening and decomposition of stubborn stains on the surface to be cleaned. At the same time, it has a certain bactericidal effect on the surface to be cleaned, enriching the usage environment of the cleaning equipment and improving the cleaning effect.

[0053] To ensure that the steam module 2 and the solution module 3 can be interchangeably configured on the cleaning equipment, in the embodiments of this application, the steam module 2 and the solution module 3 can be constructed as follows:

[0054] In one configuration of the steam module 2 and solution module 3 in the cleaning equipment, the two are adaptively designed with different shapes based on their respective structures and usage requirements, and thus can be interchangeably assembled in different accommodating spaces within the cleaning equipment. Specifically, see... Figure 4 Taking the orientation shown in the figure as an example, the upper and lower parts of the body 1 are respectively equipped with receiving tanks for solution module 3 and steam module 2, and the bottom surface of each receiving tank is equipped with a first inlet connector 11. When steam module 2 and solution module 3 are arranged in the receiving tank, the first inlet connector 11 corresponds to the fluid outlet of steam module 2 and solution module 3 and is in fluid communication with distributor 52.

[0055] Optionally, the receiving tank is also equipped with a fastener (not shown in the figure) that cooperates with the steam module 2 or the solution module 3. The fastener adopts an elastic buckle, latch or other method that can stably install the solution module 3 or the steam module 2 on the body 1.

[0056] Another construction method for the steam module 2 and solution module 3 in the cleaning equipment is that they are constructed with the same shape and can be interchangeably assembled in the same accommodating space of the cleaning equipment. Specifically, the upper or lower part of the side shell of the body 1 is provided with a receiving groove, and the bottom surface of the receiving groove is provided with a first inlet connector 11. When the steam module 2 and solution module 3 are arranged in the receiving groove, the first inlet connector 11 corresponds to the output end of the steam module 2 and solution module 3 and is in fluid communication with the distributor 52.

[0057] Optionally, the receiving groove is also equipped with a fastener similar to that in the previous construction (not shown in the figure).

[0058] Another possible configuration of the steam module 2 and solution module 3 in the cleaning equipment is as follows: (See...) Figure 5 The solution module 3 is removably mounted on the body 1, while the steam module 2 can be selectively mounted on either the body 1 or the floor brush assembly 5. Specifically, the outer shell of the body 1 is equipped with receiving slots for the steam module 2 and the solution module 3, while the top shell of the floor brush assembly 5 has a corresponding mounting position for the steam module 2, which has a second inlet connector 12 that connects to the output end of the steam module. Furthermore, when the cleaning environment is spacious, the steam module 2 can be mounted on the top shell of the floor brush assembly 5 to shorten the steam pipe length and improve heat utilization; when the cleaning environment has a limited height, the steam module 2 can be mounted on the body 1 so that the floor brush assembly 5 can extend into the limited space for cleaning, making the cleaning equipment suitable for more cleaning environments.

[0059] In some application scenarios where the steam module 2 is installed on the floor brush assembly 5, the interface connection between the steam module and the floor brush assembly may be unstable due to uneven installation location. In some embodiments of the present invention, the bottom of the steam module 2 and the floor brush assembly 5 may be provided with feet, pads, or other support components (not shown in the figure) that can make the steam module 2 stable.

[0060] It should be noted that the body 1 and the floor brush assembly 5 can be configured with fluid lines corresponding to the steam module 2 and the solution module 3 respectively; or only one fluid line common to both the steam module 2 and the solution module 3 can be configured. When using a common fluid line, it is only necessary to connect the inlet connector of each corresponding module to the fluid line.

[0061] To prevent fluid leakage from the outlets of steam module 2 and solution module 3, in some embodiments, the fluid outlets of steam module 2 and solution module 3 are configured with structures such as flexible check valves, see [link to relevant documentation]. Figure 5 When the steam module 2 or the solution module 3 is installed on the cleaning equipment, the inlet connectors 11 and 12 extend into the fluid outlet to open the flexible check valve and complete the connection. When the inlet connectors 11 and 12 are disconnected from the fluid outlet, the flexible check valve automatically closes the outlet.

[0062] To ensure that either the steam module 2 or the solution module 3 can be identified when installed on the cleaning equipment, in some embodiments, an identification element (not shown in the figure) is configured at any location that can detect whether the steam module 2 or the solution module 3 is installed on the cleaning equipment, such as the fluid outlet or inlet connector 11 / 12 of the steam module or solution module. This identification element sends a signal to the control device after detecting the installation of the steam module. The identification element can be an optical sensor, a proximity switch, a reed switch, or any other sensor capable of detecting whether the steam module 2 or the solution module 3 is installed on the cleaning equipment. For example, an infrared sensor is installed in the fluid outlet of the steam module 2 or the solution module 3. When the steam module 2 or the solution module 3 is installed on the cleaning equipment, the inlet connector 11 / 12, extending into the fluid outlet, will block the infrared light. The infrared receiver, unable to receive infrared light, will then send a signal to the control system, thereby displaying and / or indicating the current installation status of the steam module 2 or the solution module 3.

[0063] refer to Figure 6 The diagram shows the main structure of the steam module 2. The steam module 2 includes a housing 21, within which a supply box 22, a steam generator 23, and an output terminal 24 are housed. The supply box 22 is in fluid communication with the steam generator 23, and the steam generator 23 is in fluid communication with the output terminal 24. When the steam module 2 is configured on a cleaning device, the output terminal 24 is connected to the inlet connector on the body 1 or the floor brush assembly 5.

[0064] The supply tank 22 is detachably mounted on the steam module 2 to fill water or solution, or the supply tank 22 can be directly filled with water or solution on the steam module 2. In some embodiments of the invention, a liquid level detection element is installed inside the supply tank 22. When the liquid level detection element detects that the tank is low on water, it sends a signal to the control system. The detection element can be a float switch, a capacitive proximity switch, a pressure sensor, a photoelectric sensor, or any other sensor capable of detecting whether the tank is low on water. Furthermore, a temperature detection element can be installed inside the steam generator 23, and a pressure detection element can be installed inside the steam pipeline. The aforementioned detection elements are coupled to the control system to display and / or indicate the status of the steam tank, the steam generator, and the steam flow rate.

[0065] Optionally, to make the liquid output from the steam tank easier to flow and control, a pump 25 is provided between the supply tank 22 and the steam generator 23, and the solution flows from the supply tank 22 to the steam generator 23 via the pump 25.

[0066] In some application scenarios of the present invention, water or solution is guided from the supply tank 22 to the steam generator 23 by the pump 25, converted into steam, and then sent to the floor brush assembly 5, external accessories, or directly sprayed onto the surface to be cleaned through the output end 24. The stains on the surface to be cleaned are decomposed and softened by the high temperature of the steam to improve the cleaning effect, and at the same time, it can also play a certain role in sterilization.

[0067] Optionally, the steam module 2 also includes a first power supply unit 27, which is coupled to the steam generator 23, the pump 25, or various monitoring elements. Further, when the steam module 2 is configured on a cleaning device, the first power supply unit 27 can also be coupled to connectors configured at inlet connectors 11 and 12 to be coupled to various electrical components of the cleaning device. For details regarding the power supply modes of the steam module 2 or the cleaning device, please refer to the detailed description in the following section on cleaning device power supply modes.

[0068] Since the steam module 2 and the solution module 3 are configured on the cleaning equipment, the fluid is distributed to the roller brush and / or the surface to be cleaned through the distributor 52. However, the location where the fluid is distributed varies in different application scenarios. Therefore, the distributor 52 can be configured in different configurations.

[0069] One configuration of distributor 52 is, as referenced Figure 7 The distributor 52 includes a nozzle 521 and a fluid supply line, wherein one port of the fluid supply line is connected to the nozzle 521 and the other port is connected to the inlet connectors 11 and 12. In one embodiment, the nozzle 521 is directed toward the surface of the roller brush, thereby causing the fluid to be sprayed toward the roller brush to indirectly contact the surface to be cleaned; in another embodiment, the nozzle 521 is directed toward the surface to be cleaned, thereby causing the fluid to be sprayed directly toward the surface to be cleaned, improving the effect of steam softening of stains and dust suppression.

[0070] It is worth noting that the number of nozzles can be adapted to the application scenario, such as setting up a row of nozzles facing the surface to be cleaned or a roller brush. The required number of nozzles varies in different application scenarios, and those skilled in the art can adapt the number of nozzles and their connection method based on usage requirements.

[0071] Another configuration of distributor 52 is, as referenced Figure 8The distributor 52 includes a steam nozzle 5211, a solution nozzle 5212, a reversing valve 522, and a fluid supply line. Two ports of the reversing valve 522 are connected to the steam nozzle 5211 and the water nozzle 5212, and the other port is connected to the inlet connector 11 / 12 via the fluid supply line. In one embodiment, the steam nozzle 5211 is arranged on the top shell of the floor brush assembly 5 at the end away from the body 1 and faces the surface to be cleaned, and the solution nozzle 5212 is arranged inside the floor brush assembly 5 with the nozzle facing the roller brush surface.

[0072] In some application scenarios of the present invention, when the solution module 3 is configured on the cleaning equipment, the first inlet connector 11 is connected to the solution outlet of the solution tank 31, and the solution can flow sequentially through the first inlet connector 11 and the fluid supply pipeline to the nozzle 521, and further be guided to the water nozzle 5212 through the reversing valve 522 to spray onto the roller brush surface; when the steam module 2 is configured on the cleaning equipment, the inlet connectors 11 and 12 are connected to the output end 24, and the steam fluid can flow sequentially through the inlet connectors 11 and 12 and the fluid supply pipeline to the nozzle 521, and further be guided to the steam nozzle 5211 through the reversing valve 522 to spray onto the surface to be cleaned.

[0073] The following is combined Figures 9a-9b The cleaning modes of the cleaning equipment are described below. The cleaning equipment of the present invention can be switched to at least one of the following cleaning modes:

[0074] Deep cleaning mode, see reference. Figure 9a The steam module 2 is configured on the cleaning equipment to enable the steam module 2, roller brush 51 and suction source 42 to work and switch to deep cleaning mode. Specifically, after the steam module 2 is installed on the cleaning equipment, the output end 24 is connected to the first inlet connector 11 on the machine body 1 or the second inlet connector 12 on the floor brush assembly 5. The pump 25 and steam generator 23 are started. The water or solution in the supply tank 22 flows to the steam generator 23 through the pump 25. The generated steam is sprayed out from the steam nozzle 5211 on the floor brush assembly 5 through the inlet connector 11 / 12. Under the action of hot steam, the stubborn stains on the surface to be cleaned are softened and decomposed faster. At the same time, the roller brush 51 on the floor brush assembly 5 rotates at high speed to stir and sweep the stains on the ground and sweep the stains into the floor brush assembly 5. Then, the stains are sucked into the collection bucket 41 by the suction force of the collection channel 53. The collection bucket 41 separates the sewage and solid stains and collects them separately. The air is filtered and discharged through the air outlet of the suction source 42. To achieve better cleaning results, the steam module 2 can also control the steam generator 23 to work intermittently to distribute steam or solution to the steam nozzle 5211 at intervals. Through the combination of steam and solution, the stains on the surface to be cleaned can be cleaned more efficiently.

[0075] Light cleaning mode, see reference. Figure 9bThe solution module 3 replaces the steam module 2 in the cleaning equipment, enabling the roller brush 51, suction source 42, and solution module 3 to work and switch to a light cleaning mode. Specifically, after the solution module 3 is installed on the body 1, the fluid outlet of the solution tank 31 is connected to the first inlet connector 11. The water or solution in the solution tank 31 is sprayed out from the solution nozzle 5212 by a pump or by its own weight. At the same time, the roller brush 51 on the floor brush assembly 5 rotates at high speed to agitate and sweep the stains on the floor and sweep the stains into the floor brush assembly 5. The recovery channel has negative pressure suction, which sucks the sewage and solid waste into the recovery tank 41. Then, the stains are sucked into the recovery tank 41 by the suction force of the recovery channel 53. The recovery tank 41 separates the sewage and solid stains and collects them separately. The air is filtered and discharged through the air outlet of the suction source 42.

[0076] Dry cleaning mode, see reference Figure 1 The cleaning equipment is not equipped with a steam module 2 or a solution module 3. The roller brush 51 and the suction source 42 work together. The stains on the surface to be cleaned are agitated by the roller brush 51 and then sucked into the collection bucket 41 through the collection channel. The collection bucket separates and collects the stains separately. The air is filtered and discharged through the air outlet of the suction source 42.

[0077] It is worth noting that, as indicated in the appendix to this application's specification... Figures 9a-9b The example provided illustrates the configuration of steam module 2 and solution module 3 at different locations on the body 1, but is not limited to this. Steam module 2 and solution module 3 can be configured in any desired configuration, for example, by constructing them in the same shape for interchangeable assembly within the same accommodating space on the cleaning equipment. The common feature of these configurations is that steam module 2 and solution module 3 are interchangeably configured on the cleaning equipment and can work in conjunction with other components.

[0078] The following is combined Figures 10a-10b The power supply mode of the cleaning equipment is described.

[0079] The steam module 2 is equipped with a first power supply unit 27, and the body 1 is equipped with a second power supply unit 13. When the steam module 2 is installed on the cleaning equipment, the first power supply unit 27 and / or the second power supply unit 13 supply power to the entire equipment. Specifically:

[0080] When the cleaning equipment is in deep cleaning mode, that is, after the steam module 2 is configured on the cleaning equipment, the entire cleaning equipment can be powered by the first power supply unit 27 and / or the second power supply unit 13.

[0081] When the cleaning equipment is in light cleaning mode or dry cleaning mode, that is, when the cleaning equipment is not equipped with steam module 2, the entire cleaning equipment is powered by the second power supply unit 13.

[0082] It is understood that power supply units one and two can use wired power or batteries. In different application scenarios of this invention, power supply units one and two can use the same or different power types and can be used individually or in combination. In addition, when the power supply unit uses a battery, the battery can be detachably installed on the body 1 or the steam module 2 for charging, or the battery can be charged directly on the body 1 or the steam module 2 using a wired or wireless method.

[0083] refer to Figure 10a This illustrates one configuration of the power supply units of the cleaning equipment. The first power supply unit 27 uses a connector for connection to an external power source, while the second power supply unit 13 uses a battery. The battery in the second power supply unit 13 powers the equipment in the low-power light cleaning and dry cleaning modes, allowing the cleaning equipment to adapt to more application scenarios. In the high-power deep cleaning mode, the connector in the first power supply unit 27 connects to an external power source, ensuring the cleaning equipment's extended usage time.

[0084] Alternatively, the first power supply unit 27 uses a battery, and the second power supply unit 13 uses a connector that connects to an external power source. When the steam module 2 is configured on the cleaning equipment, the second power supply unit 13 is used for power supply.

[0085] Furthermore, when the first power supply unit 27 or the second power supply unit 28 uses a connector, a winding structure can be provided on the machine body. In one embodiment, the winding structure includes at least two hooks, one of which is rotatable so that the wire can be detached.

[0086] refer to Figure 10b This illustrates an alternative configuration for the power supply units of the cleaning equipment. Both the first power supply unit 27 and the second power supply unit 13 utilize batteries, making the use of the cleaning equipment more convenient and less limited by the environment.

[0087] Optionally, when the first power supply unit 27 and / or the second power supply unit 13 uses a battery, the steam module 2 and / or the body 1 are correspondingly equipped with a power monitoring element. The power monitoring element can be a voltage tester, a coulomb meter, or any other structure that can monitor the battery power in real time.

[0088] Another way to construct the power supply units of the cleaning equipment is that the body 1 is equipped with a connector for connecting to an external power source and a battery. When the solution module 3 is installed on the cleaning equipment, it is powered by a battery; when the steam module 2 is installed on the cleaning equipment, it is powered by a connector connected to an external power source.

[0089] The following examples illustrate the application of the cleaning equipment in the embodiments of this application.

[0090] 1. When the stains on the surface to be cleaned are of the type such as dust or water stains, the user can select the dry cleaning or light cleaning mode of the cleaning equipment, and then hold the handle to guide the movement of the floor brush assembly 5. At the same time, the user can manually control the rotation of the roller brush 51 through a switch, button or other form of brake switch, or automatically control the rotation of the roller brush 51 through a contact switch, sensor or other form of sensing device. In dry cleaning mode, the roller brush 51 agitates and sweeps the stains on the surface to be cleaned. The removed stains are sucked into the collection bin 41 for separation and collection, and the air is filtered and discharged through the air outlet of the suction source 42.

[0091] In the light cleaning mode, the user configures the solution module 3 on the cleaning device. When the recognition element senses that the configuration is complete, the main control unit controls the roller brush 51 and the suction source 42 to perform the above operations. At the same time, the solution in the solution tank 3 is guided to the dispenser 52 by the pump or by its own weight and sprayed onto the surface to be cleaned or the roller brush 51.

[0092] 2. When the stains on the surface to be cleaned are stubborn types such as oil stains, food stains, and seasonings (e.g., in kitchens, restaurants, etc.) or when sterilization is required, the user can configure the steam module 2 on the cleaning equipment and select the deep cleaning mode. Then, hold the handle to guide the movement of the floor brush assembly 5, and simultaneously start the roller brush 51 to rotate. The pump 25 of the steam module 2 automatically guides the fluid. The steam generated by the steam generator 23 is distributed to the nozzles on the floor brush assembly 5 through the first inlet connector 11 or the second inlet connector 12 to spray onto the surface to be cleaned or the roller brush. Under the action of hot steam, the stubborn stains on the surface to be cleaned are decomposed more quickly, and the surface to be cleaned is disinfected. Alternatively, the steam generator 23 can work intermittently, so that the steam module 2 can periodically distribute steam or solution to the surface to be cleaned through the steam nozzles 5211. The roller brush 51 agitates and sweeps the stains on the surface to be cleaned. The removed stains are sucked into the recycling bin 41 for separation and collection. The air is filtered and discharged through the air outlet of the suction source 42.

[0093] This invention provides another cleaning device, which is structurally similar to the cleaning device provided in the above embodiments. The difference lies in that, in this embodiment, the steam module 2 and the solution module 3 can be configured in any suitable position on the cleaning device. For example, the floor brush assembly 5 is provided with a mounting position, which is equipped with an inlet connector communicating with the distributor 52. The steam module 2 and the solution module 3 can be alternatively configured in this mounting position and communicated with the inlet connector.

[0094] This invention provides yet another cleaning device, which is structurally similar to the cleaning device provided in the above embodiments. The difference is that in this embodiment, the steam module 2 is configured to work independently as a portable steam engine.

[0095] Specifically, refer to Figure 11 The steam module 2 also includes a display control unit 26 disposed on the surface of the housing 21. The display control unit 26 is equipped with an input unit, a control unit, and a display unit coupled to the control unit. The input unit is configured as a button, switch, voice, or any other structure that enables signal interaction between the user and the control unit. The control unit is coupled to the liquid level detection element, temperature detection element, pressure detection element of the steam module 2, as well as the brake switch of the pump 25 and the steam generator 23. The display unit is used to display and / or indicate the status of the steam module 2, such as the solution volume and steam flow rate.

[0096] After the steam module 2 is removed from the cleaning equipment, the display control unit 26 receives the user's instructions and controls the working status of the steam generator 23 and the pump 25, such as controlling the steam generator 23 and the pump 25 to work so that steam is generated at the outlet 24 for cleaning stains.

[0097] To further facilitate use and enrich the application scenarios of the cleaning equipment of the present invention, the steam module 2 can also work independently with the external accessory 6 of the cleaning equipment. The user holds the external accessory 6 to disinfect and clean the surface to be cleaned.

[0098] refer to Figure 12 The diagram shows the main structure of the external attachment 6 of the cleaning equipment. The external attachment 6 includes a cleaning unit 61 and a fluid distribution unit 62. The cleaning unit 61 is configured as a bristle-embedded, roller brush or other structure that can agitate the stains on the surface to be cleaned. The cleaning unit 61 is located at the end of the external attachment 6 and is used to agitate the surface to be cleaned. The fluid distribution unit 62 is located on one side of the cleaning unit 61 and its outlet faces the surface to be cleaned. When the external attachment 6 is connected to the steam module 2, the fluid distribution unit 62 is in fluid communication with its output end.

[0099] Optionally, the external accessory 6 also includes a suction unit 63, located on the other side of the cleaning unit 61 with its opening facing the surface to be cleaned. When the external accessory 6 is installed on the floor brush assembly 5, the cleaning unit 61 and the suction unit 63 are in fluid communication with the solution module 3 and the recovery tank assembly 4, respectively. Specifically, the floor brush assembly 5 is equipped with solution supply lines and fluid recovery lines corresponding to the solution module 3 and the recovery tank 41. Each of these lines is equipped with a regulating valve (not shown in the figure). The outlet of the regulating valve in the solution supply line is in fluid communication with the distributor 52 in the floor brush assembly 5 and the fluid distribution unit 62 in the external accessory 6, respectively. The outlet of the regulating valve in the fluid recovery line is in fluid communication with the recovery channel 53 in the floor brush assembly 5 and the suction unit 63 in the external accessory 6, respectively. Furthermore, the solution module 3 and the recovery tank 41 can be switched to be in fluid communication with either the floor brush assembly 5 or the external accessory 6 via the regulating valves in the aforementioned lines to execute different working modes.

[0100] The following is combined Figure 11 The operating mode of the steam module when connected to external accessories is explained.

[0101] Steam module 2 is removed from the cleaning equipment and connected to external accessory 6. The output end 24 of the steam generator distributes steam to the surface to be cleaned. Specifically, after steam module 2 is removed from the body 1 or the floor brush assembly 5, it is connected to external accessory 6, so that the output end 24 is connected to the fluid distribution unit 62 of external accessory 6. Then, pump 25 and steam generator 23 are started. Water or solution in supply tank 22 flows to steam generator 23 through pump 25. The generated steam is guided to fluid distribution unit 62 through output end 24 and sprayed onto the surface to be cleaned. At the same time, cleaning unit 61 agitates the stains on the surface to be cleaned. During this process, first power supply unit 27 supplies power to the electrical components of steam module 2. The user can control the working status of pump and steam generator through display control unit 26. In steam mode alone, the hot steam output by steam module 2 will accelerate the decomposition of stains on the surface to be cleaned, making it easier to clean the stains. At the same time, the hot steam can disinfect the surface to be cleaned, improving the cleaning effect.

[0102] The following is combined Figure 13 The control system of the cleaning equipment in this embodiment will be described.

[0103] The cleaning equipment control system of this embodiment includes a main unit control unit 14 installed on the machine body 1 and a display control unit 26 installed on the steam module 2. The main unit control unit 14 is coupled to the detection, display, prompting, and actuation components in the handle, solution module 3, recycling bin assembly 4, and floor brush assembly 5. The display control unit 26 is coupled to the detection, display, prompting, and actuation components in the supply box 22, pump 25, and steam generator 23.

[0104] When the steam module 2 is used alone, the display control unit 26 controls the various components on the steam module 2. The user can control the steam module 2 using buttons, switches, keys, voice user interface or any other means that enable the user to interact with the display control unit 26.

[0105] When the steam module 2 is installed on the cleaning equipment, i.e. the cleaning equipment is in deep cleaning mode, the main control unit 14 is connected to the display control unit 26, and the entire cleaning equipment can be controlled through the main control unit 14 or the display control unit 26.

[0106] When the solution module 3 replaces the steam module 2 and is configured on the cleaning equipment, or when neither of them is configured on the cleaning equipment, that is, when the cleaning equipment is in light cleaning mode or dry cleaning mode, the main control unit 14 controls the entire cleaning equipment.

[0107] The following examples illustrate the application of the cleaning equipment in the embodiments of this application.

[0108] 3. When the surface to be cleaned is a crevic or corner, kitchen countertop stains, area around the kitchen range hood, bathroom corner dirt and mold, children's toys, clothes and wardrobes that have been stored for a long time, sofas and mattresses, etc., the user removes the steam module 2 from the cleaning device and connects it to the external accessory 6, so that the output end 24 is connected to the corresponding connector of the external accessory 6. At the same time, the user holds the outer shell of the external accessory 6 and guides the external accessory 6 to move on the surface to be cleaned. The display control unit 26 controls the working status of the pump 25 and the steam generator 23. When the steam generator 23 is working, the hot steam generated is sprayed onto the surface to be cleaned through the output end 24. At the same time, when the user guides the external accessory 6 to move, the cleaning unit 61 can agitate the softened and decomposed stains to remove the stains from the surface to be cleaned.

[0109] IV. When the surface to be cleaned contains stains that have already been softened and decomposed, as described above, the user connects the external accessory 6 to the floor brush assembly 5 and simultaneously selects the external accessory mode of the cleaning device via a switch, button, or other trigger. At this time, the collection bin assembly 4 and the suction unit 63 of the external accessory 6 are in fluid communication. The user then holds the outer casing of the external accessory 6 and guides it to move on the surface to be cleaned. The cleaning unit 61 further agitates the stains on the surface, and the suction unit 63 sucks in the removed stains and directs them into the collection bin 41 for collection. Alternatively, when the surface to be cleaned is a wardrobe, sofa, kitchen countertop, crevices, vehicle, etc., and the stains are dust, mud, etc., the user can use... The user connects the external accessory 6 to the floor brush assembly 5 and simultaneously configures the solution module 3 on the cleaning device. When the identification element senses that the configuration is complete, the user selects the external accessory mode of the cleaning device through a switch, button, or other trigger. At this time, the solution module 3 and the recycling bin assembly 4 are fluidly connected to the fluid distribution unit 62 and the suction unit 63 of the external accessory 6, respectively. Next, the user holds the outer shell of the external accessory 6 and guides the external accessory 6 to move on the surface to be cleaned. The cleaning unit 61 further agitates the stains on the surface to be cleaned. The solution module 3 distributes the cleaning solution to the surface to be cleaned through the fluid distribution unit 62. The suction unit 63 sucks in the removed stains and guides them into the recycling bin 41 for collection.

[0110] In summary, this invention provides a cleaning device in which the solution module and steam module are interchangeably configured. This allows the device to be switched to a suitable cleaning mode for different application scenarios, achieving multi-functionality and expanding its application scenarios. Furthermore, the steam unit can be disassembled and used as a portable steam sterilizer, making it more portable and economical. Simultaneously, the cleaning device of this invention offers multiple power supply modes, which can be freely switched in different application scenarios, making it more convenient for users and freeing them from limitations imposed by specific scenarios.
