DETAILED DESCRIPTION

[0060] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the first heating component in the specification is described in conjunction with a ceramic heater, the present application can obviously use other devices for heating, such as electric heating rods, metal heating wires, etc.

[0061] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "set", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0062] like Figure 1-12 As shown, the floor cleaning device of the present application is described to solve the problem that the operator cannot accurately judge the heating temperature required for different stains, which leads to a decrease in cleaning effect and may cause a waste of energy. The present invention provides a floor cleaning device, including a housing 4, a water storage tank 71, a roller brush body 1, a first heating component 73, a second heating component and a stain detection component; a receiving recess 41 for accommodating the roller brush body 1 is formed on the housing 4, the roller brush body 1 is arranged in the receiving recess 41 and is used to clean the floor, the first heating component 73 is used to heat the liquid flowing to the roller brush body 1, the second heating component is used to heat the roller brush body 1, and the stain detection component is arranged in the housing 4 and is configured to be able to detect the type of stains.

[0063] In this way, the first heating component 73 can heat the liquid flowing to the roller brush body 1, and the second heating component can heat the roller brush body 1. When the first heating component 73 and the second heating component are turned on at the same time, even relatively stubborn stains can be heated and dissolved, achieving a better cleaning effect.

[0064] It should be noted that the stain detection component includes a visual sensor. The visual sensor is connected to the front side of the housing 4 ( Fig.11The outer shell 4 is connected to the lower right side of the paper surface of the middle outer shell 4) and faces the position to be cleaned to shoot the front side of the position to be cleaned. The big data learning algorithm is used to train the labeled stain image samples so that it can automatically learn and identify the stains according to the images collected by the visual sensor. The specific algorithm and recognition principle are conventional means in this field and will not be repeated in this application. At the same time, an illumination lamp is also provided on the front side of the outer shell 4. The illumination lamp is used to illuminate the front area of ​​the outer shell 4 to make the image collected by the visual sensor clearer. It should be noted that the position where the visual sensor is set is not necessary, and those skilled in the art may also set the visual sensor on one side of the outer shell 4 ( Fig.11 The lower left side of the outer shell 4 in the paper direction) or the lower side of the outer shell 4, as long as the front side of the outer shell 4 can be photographed. Furthermore, the use of a visual sensor to detect the type of stain is the best choice. Of course, other sensors can also be used, such as chemical sensors or infrared sensors. Chemical sensors use chemical principles to detect ground stains. Chemical sensors can determine the type of stains by detecting specific chemicals or odors on the stains. For example, a gas sensor can detect the concentration of volatile organic compounds (VOCs) to determine whether there are grease stains. Infrared sensors use the principle of infrared radiation to detect ground stains. Infrared sensors can measure the intensity of infrared radiation on the surface of the stain. Different types of stains will have different effects on infrared radiation, so different types of stains can be distinguished. At the same time, the setting of the lighting lamp is not necessary. Those skilled in the art can also set the lighting lamp at other positions, as long as the area on the front side of the outer shell 4 can be illuminated. Of course, the lighting lamp can also be not set.

[0065] like Figure 1-12 As shown, in a floor cleaning device provided in a preferred embodiment of the present invention, the floor cleaning device includes a housing 4, a roller brush body 1, a handheld frame 6, a water storage tank 71, a water guide channel, a first heating component 73, a battery and a power detection component.

[0066] like Figure 9-12 As shown, a receiving recess 41 for receiving the roller brush body 1 is formed on both sides of the housing 4, and the number of the roller brush bodies 1 is two. The two roller brush bodies 1 are respectively arranged in the two receiving recesses 41 and are used to clean the floor. A spraying member 74 is arranged on the housing 4, and the spraying member 74 is arranged toward the roller brush body 1. One end of the hand-held frame 6 is connected to the housing 4, and an armrest is arranged on the other end of the hand-held frame 6, and a mounting groove for mounting the water storage tank 71 is formed on the hand-held frame 6. A power supply terminal 42 is arranged on the receiving recess 41, and the power supply terminal 42 is used to supply power to the roller brush body 1.

[0067] It should be noted that the provision of the accommodating recess 41 is not mandatory, and those skilled in the art may choose whether to provide the accommodating recess 41 and the specific structure of the accommodating recess 41 based on the specific application scenario. Of course, the accommodating recess 41 may not be provided.

[0068] The water tank 71 is embedded in the mounting groove, one end of the water channel is connected to the water tank 71, and the other end of the water channel is connected to the spraying member 74. A pump body 72 is connected to the handheld frame 6, and the pump body 72 is connected to the water channel. The pump body 72 can pump the liquid in the water tank 71 to the spraying member 74. The first heating component 73 is arranged in the housing 4, and is used to heat the water in the water channel. The spraying member 74 can spray the hot water heated by the first heating component 73 onto the roller brush body 1.

[0069] The number of the spraying parts 74 is also set to two, and the two spraying parts 74 spray the two roller brush bodies 1 respectively. The spraying part 74 includes a long strip spraying shell, and a nozzle is provided on the side of the spraying shell facing the roller brush body 1, and the length of the spraying shell is less than or equal to the length of the roller brush body 1, and the spraying part 74 is fixedly connected to the housing 4.

[0070] It should be noted that the position and specific setting of the spraying member 74 can also be adjusted according to actual needs. For example, the spraying member 74 can also be set above the roller brush body 1, and the nozzle is set at the lower side of the spraying member 74 and facing the roller brush body 1. At this time, the water flow is sprayed from above to the roller brush body 1. In addition, the appearance and setting form of the spray shell or nozzle are not unique, as long as it can achieve the spraying effect.

[0071] The pump body 72 can pump water to the two spray parts 74 respectively through the bifurcated pipe. After the water is sent to the spray parts 74 by the pump body 72, the water is sprayed evenly to the roller brush body 1 because the spray parts 74 are evenly provided with nozzles. Of course, although in this embodiment, the length of the spray shell needs to be less than or equal to the length of the roller brush body 1 due to the position relationship, the two ends of the roller brush body 1 can be wetted by changing the angle of the nozzle toward the roller brush body 1.

[0072] It should be noted that the pump body 72 is not necessarily provided. Those skilled in the art can choose whether to provide the pump body 72 and the specific structure of the pump body 72 based on the specific application scenario. Of course, the pump body 72 may not be provided. The liquid in the water storage tank 71 reaches the nozzle and is sprayed out under the action of gravity. Of course, the pump body 72 may be provided in the housing 4 or on the handheld frame 6.

[0073] The first heating component 73 is heated by a ceramic heater, and of course, it can also be heated by an electric heating rod, a metal heating wire, etc., as long as it can heat the water flow, and can heat the water in the water guide channel and the water in the water storage tank 71. Fig. 9 As shown, it should be noted that the water in the water tank 71 passes through the pump body 72, the first heating component 73 and the spraying part 74 in sequence, and the water is sprayed onto the roller brush body 1 through the spraying part 74. Of course, the above water flow sequence is the best, and other flow modes can also be used, such as the water in the water tank 71 passes through the first heating component 73, the pump body 72 and the spraying part 74 in sequence; or the first heating component 73 heats the water in the water tank 71, and then passes through the pump body 72 and the spraying part 74.

[0074] It should be noted that the handheld frame 6 is not necessarily provided, and those skilled in the art can choose whether to provide the handheld frame 6 and the specific structure of the handheld frame 6 based on the specific application scenario. Of course, the handheld frame 6 may not be provided, and the water storage tank 71, the pump body 72, etc. may be directly provided on the upper side of the housing 4. Accordingly, on the basis of not providing the handheld frame 6, the armrest is not necessarily provided.

[0075] The battery is used to power the components of the floor cleaning device that require electricity, and the power detection component is used to detect the remaining power in the battery. Of course, the setting of the power detection component is not necessary, and those skilled in the art can choose whether to set the power detection component and the specific structure of the power detection component based on the specific application scenario, and of course, the power detection component can also be not set.

[0076] See attached Figure 1-4 The floor cleaning device further comprises a plug-in portion 22, a fixing portion 21, an end cover 3, a second heating component and a driving component. The second heating component comprises a heating wire 51 and a heating element 52, the heating wire 51 is electrically connected to the heating element 52, and the heating element 52 can generate heat when powered.

[0077] The roller brush body 1 is a hollow tubular structure. A heating element 52 is connected to the outside of the roller brush body 1 . Bristles 11 for cleaning the floor are arranged on the outside of the heating element 52 .

[0078] See attached Figure 3-8 The plug-in portion 22 includes a plug-in block 221 and a mounting rod 222. The plug-in block 221 is a cylindrical shape with one end open. The bottom surface and the inner side wall of the plug-in block 221 are formed with a wire groove 225, and the wire groove 225 is used for the heating wire 51 to pass through. The open end of the plug-in block 221 is provided with a flange 2211 to the outside. The plug-in block 221 is inserted into the roller brush body 1, and the flange 2211 abuts against the end surface of the roller brush body 1. The flange 2211 is provided with a notch 226 for the heating wire 51 to pass through. The abutment of the flange 2211 with the end surface of the roller brush body 1 can prevent liquid from entering the roller brush body 1, improve the waterproof performance of the roller brush body 1 and the plug-in block 221, and can be conveniently connected to the heating element 52 through the notch 226.

[0079] It should be noted that, for the sake of convenience, the wire-releasing groove 225 provided on the bottom surface of the plug-in block 221 is named as the first wire-releasing groove, and the wire-releasing groove 225 provided on the inner side surface of the plug-in block 221 is named as the second wire-releasing groove. The first wire-releasing groove is formed by the bottom surface of the plug-in block 221 being recessed downward, and two guide plates 227 are fixedly connected to the side surface of the plug-in block 221, and the two guide plates 227 and the inner side wall of the plug-in block 221 are surrounded to form the second wire-releasing groove.

[0080] See Appendix Figure 7 The mounting rod 222 is formed at the cylindrical bottom of the plug-in block 221. The mounting rod 222 is coaxially arranged with the plug-in block 221, and a connecting hole is provided on the mounting rod 222. The connecting hole is used to plug the connecting shaft 23. The fixed part 21 and the plug-in part 22 are rotatably connected through the connecting shaft 23. It should be noted that the plug-in block 221 and the mounting rod 222 are described separately here only for the convenience of clear description. Of course, the plug-in block 221 and the mounting rod 222 can be integrally formed or fixedly connected.

[0081] The mounting rod 222 is provided with a first conductive component, which includes a conductive ring 24. The cross section of the conductive ring 24 is square. There are two conductive rings 24. The conductive rings 24 are sleeved on the mounting rod 222 and fixed to the mounting rod 222. At the same time, the mounting rod 222 is also provided with a limiting rib 224. A limiting groove 241 is provided on the inner side of the conductive ring 24. When the conductive ring 24 is sleeved on the mounting rod 222, the limiting rib 224 is inserted into the limiting groove 241, which can prevent the conductive ring 24 and the mounting rod 222 from rotating relative to each other. There are two limiting ribs 224 and two limiting grooves 241.

[0082] See attached Figure 3-6The fixing part 21 includes a fixing base 214, a wire fixing plate 211 and a bearing 215, and the second conductive component includes a spring piece 217 and a conductive block 218. The fixing base 214 is plugged into the plug-in part 22, and a bearing 215 is provided in the fixing base 214. A connecting shaft 23 passes through the bearing 215, and the connection between the fixing part 21 and the plug-in part 22 is realized through the connecting shaft 23, and the rotation between the fixing part 21 and the plug-in part 22 is realized through the bearing 215. The connecting shaft 23 ensures that when the fixing part 21 and the plug-in part 22 rotate relative to each other, the rotation axis of the fixing part 21 and the plug-in part 22 will not change, thereby making the connection between the conductive block 218 and the conductive ring 24 more stable. The fixing base 214 is provided with a fixing protrusion 216. One end of the spring sheet 217 is located on the upper side of the fixing protrusion 216. The spring sheet 217 is fixedly connected to the fixing protrusion 216 by a bolt, and a threading hole 219 is provided on the end. The other end of the spring sheet 217 is fixedly connected to the conductive block 218. The elastic force of the spring sheet 217 makes the conductive block 218 always in a state of pressing the outer surface of the conductive ring 24. The first end ( Figure 6 The middle wire fixing plate 211 is close to the right side) and is connected to one end of the outer side of the fixing base 214. The second end of the wire fixing plate 211 ( Figure 6 A clamping protrusion 2112 is formed on the side of the roller brush body 1 (close to the left side of the middle wire fixing plate 211), and a conductive sheet 213 is connected to the clamping protrusion 2112. A part of the conductive sheet 213 is located on the side where the clamping protrusion 2112 is flush with the wire fixing plate 211. The conductive sheet 213 on the outside of the clamping protrusion 2112 is conveniently connected to the power supply end. A wire groove 2111 is provided on the side of the wire fixing plate 211 away from the roller brush body 1, and one end of the conductive sheet 213 is located in the wire groove 2111. One end of the wire is connected to the conductive sheet 213, and the other end of the wire is connected to the threading hole 219 of the spring 217, and the wire passes through the wire groove 2111. A cover plate 212 is provided on the side of the wire fixing plate 211 away from the roller brush body 1, and the cover plate 212 can prevent the wire from being exposed to the outside.

[0083] See attached Figure 4 The heating element 52 is located on the outside of the roller brush body 1 and is used to heat the roller brush body 1. A driving groove is provided at one end of the end cover 3 close to the outside. The driving groove is used to cooperate with the driving component of the roller brush body 1, so that the roller brush body 1 rotates under the action of the driving component.

[0084] There are two heating wires 51, one end of each of which is electrically connected to two conductive rings 24, and there are two wire release grooves 225. The two heating wires 51 pass through different wire release grooves 225 and are fixed in the wire release grooves 225 to prevent the heating wires 51 from being displaced during the rotation of the roller brush body 1, which would cause instability in the power supply to the heating element 52. The heating element 52 is composed of a heating film, which is wound around the outside of the roller brush body 1, and the two poles of the heating element 52 are connected to the two heating wires 51, respectively.

[0085] Other possible implementations of the local surface cleaning device are described below.

[0086] An alternative embodiment, the above-mentioned setting positions of the heating wire 51 and the heating element 52 are the best choice. Of course, the heating wire 51 and the heating element 52 can also be set at other positions, as long as the roller brush body 1 can be heated.

The heating element 52 is fixedly connected to the inside of the roller brush body 1, and the two poles of the heating element 52 are respectively connected to the two heating wires 51.

The conductive block 218 can be pressed on any side of the conductive ring 24, as long as the conductive block 218 can be connected to the conductive ring 24.

It should be noted that the conductive block 218 here is preferably a carbon brush, and of course other conductive metal materials can also be selected.

[0097] The structures involved in the above connection method are described below.

[0102] Refer to the following Fig.13 , the startup control method of the air conditioner of the present application is introduced.

[0103] like Fig.13 As shown, corresponding to the above-mentioned floor cleaning device, the floor cleaning device control method of the present application includes:

[0104] S101, obtaining the type of stain at the position to be cleaned; for example, obtaining an image of the position to be cleaned by a visual sensor, obtaining the type of stain at the cleaning position by analyzing the image, and obtaining the type of stain at the cleaning position.

[0105] S103, determining a cleaning mode of the floor cleaning device based on the type of stain; for example, determining a cleaning mode of the floor cleaning device based on the determined type of stain, so that different stains can be more targeted and the cleaning effect can be better.

[0106] S105, based on the cleaning mode, controlling the opening and closing of the first heating component and the second heating component. For example, according to the cleaning mode, the opening and closing of the first heating component and the second heating component are controlled, that is, different cleaning modes correspond to different opening and closing states of the first heating component and the second heating component.

[0107] The floor cleaning equipment control method of the present application determines different cleaning modes according to different stain types, and turns on or off the first heating component and the second heating component. It can adaptively heat different stain types, heat the stains while cleaning them, and adopts the optimal heating method to achieve better cleaning effect on the stains.

[0108] The preferred implementation modes of the present application are introduced below.

[0109] In one embodiment, the cleaning mode of the present application includes a first mode, a second mode and a third mode.

[0110] The first mode is: the rotation speed of the roller brush body is the first rotation speed, the flow rate of the pump body is the first flow rate, and the first heating component and the second heating component are both turned off. In this way, the first heating component and the second heating component are both turned off, which saves more energy and has a longer battery life.

[0111] The second mode is: the rotation speed of the roller brush body is the second rotation speed, the flow rate of the pump body is the second flow rate, the first heating component is turned off, and the second heating component is turned on. In this way, the bristles on the outside of the roller brush body can be heated to a higher temperature, directly acting on the dirt, and having a better cleaning effect on some stains.

[0112] The third mode is: the rotation speed of the roller brush body is the third rotation speed, the flow rate of the pump body is the third flow rate, and the first heating component and the second heating component are both turned on. In this way, the first heating component and the second heating component are both turned on to reach a higher temperature, and the cleaning of stubborn stains can be more thorough.

[0113] Furthermore, the third rotation speed is less than or equal to the second rotation speed, the second rotation speed is less than or equal to the first rotation speed, the third flow rate is less than or equal to the second flow rate, and the second flow rate is less than or equal to the first flow rate. Thus, when both the first heating component and the second heating component are turned off, the rotation speed of the roller brush body and the flow rate of the pump body are the highest, resulting in a better cleaning effect on the floor. When the required temperature rises, the corresponding rotation speed and flow rate decrease. The reduced flow rate can improve the heating effect, and the reduced rotation speed can prevent heat dissipation, resulting in a better effect of cleaning stubborn stains.

[0114] It should be noted that the above settings are the best choice for the first mode, the second mode and the third mode, and those skilled in the art can also make adaptive adjustments according to specific circumstances. For example, the first mode, the second mode and the third mode only include the opening and closing of the first heating component and the second heating component, or include the opening and closing of the first heating component and the second heating component and the rotation speed of the roller brush body. Of course, in the second mode, the first heating component can also be turned on and the second heating component can be turned off.

[0115] The stain types of the present application are divided into three categories, including a first stain category, a second stain category, and a third stain category.

[0116] The first stain type includes dust and / or debris; and the first stain type is easy to clean, and can be cleaned even without heating the stain or using hot water.

[0117] The second type of stains includes oil stains, dyes and / or sludge; and the second type of stains are difficult to clean, and the stains need to be heated or hot water is used to effectively clean them.

[0118] The third type of stains includes grease and / or traces. For example, grease accumulated on the kitchen floor after a long period of time, or dye marks on the floor after the dye has dried, or mud marks on the floor after the mud has dried, or tea marks on the floor after the tea has dried. The third type of stains is the most difficult to clean, and it is necessary to use hot water and heat the stains to clean them.

[0119] In one embodiment, the step of "determining the cleaning mode of the floor cleaning device based on the stain type" further includes: if the stain type belongs to the first stain type, determining the cleaning mode of the floor cleaning device to be the first mode; if the stain type belongs to the second stain type, determining the cleaning mode of the floor cleaning device to be the second mode; if the stain type belongs to the third stain type, determining the cleaning mode of the floor cleaning device to be the third mode.

[0120] Specifically, there are two roller brush bodies, and the rotation speeds of the two roller brush bodies are different. The front roller brush body ( Fig.10 The speed of the roller brush body (the one closest to the paper surface) is: Fig.10 The rotation speed of the other roller brush body) is = 1.2:1. The rotation speed of the front roller brush body is used as the basis for explanation here. This application takes the first rotation speed of 450 rpm, the second rotation speed of 400 rpm, the third rotation speed of 350 rpm, the first flow rate of 25 ml / min, the second flow rate of 23 ml / min, and the third flow rate of 20 ml / min as an example. If the acquired stain type is the first stain type, it proves that the stain is relatively easy to clean, then the cleaning mode is determined to be the first mode. At this time, the first heating component and the second heating component are controlled to be turned off, the rotation speed of the roller brush body is the first rotation speed, that is, 450 rpm, and the flow rate of the pump body is the first flow rate, that is, 25 ml / min. In this way, by using a lower heating temperature, the floor can be effectively cleaned and electricity can be saved. If the acquired stain type is the second type of stain, which proves that the stain is relatively difficult to clean, the cleaning mode is determined to be the second mode, the first heating component is controlled to be turned off, and the second heating component is turned on; the rotation speed of the roller brush body is the second rotation speed, that is, 400 rpm, and the flow rate of the pump body is the second flow rate, that is, 23 ml / min. In this way, for stains that are generally difficult to clean, the use of medium temperature, rotation speed and flow rate can achieve effective cleaning of the floor, maximize the use of electricity, and avoid wasting electricity. If the acquired stain type is the third type of stain, which proves that the stain is relatively difficult to clean, the cleaning mode is determined to be the third mode, the first heating component and the second heating component are controlled to be turned on, the rotation speed of the roller brush body is the third rotation speed, that is, 350 rpm, and the flow rate of the pump body is the third flow rate, that is, 20 ml / min. In this way, a higher heating temperature is used to clean stubborn stains and achieve a good cleaning effect.

[0121] Of course, the specific values ​​of the first speed, second speed, third speed, first flow rate, second flow rate and third flow rate mentioned above are only exemplary. At the same time, the size relationship between the first speed, the second speed and the third speed is not necessary, and the size relationship between the first flow rate, the second flow rate and the third flow rate is not necessary. Those skilled in the art can adjust some or all of the parameters based on the specific application scenario. For example, the first flow rate, the second flow rate and the third flow rate are equal, or the first speed, the second speed and the third speed are equal. Such adjustment does not deviate from the principle of the present application.

[0122] It should be further explained that the different rotation speeds of the two roller brush bodies are preferably set, and those skilled in the art may adjust some or all of the parameters based on specific application scenarios. For example, the rotation speed of the front roller brush body may be equal to the rotation speed of the rear roller brush body, and of course the number of roller brush bodies may also be one.

[0123] In one embodiment, after the step of “determining the cleaning mode of the floor cleaning device based on the stain type”, the control method further includes:

[0124] If the cleaning mode of the floor cleaning device is the third mode, the remaining power of the battery is obtained; when the remaining power is less than the first power threshold, the cleaning mode of the floor cleaning device is adjusted from the third mode to the first mode. When the remaining power is greater than or equal to the first power threshold and less than the second power threshold, the cleaning mode is adjusted from the third mode to the second mode.

[0125] Specifically, the present application takes the remaining power as P, the first power threshold as 10%, and the second power threshold as 20% as an example for explanation. The remaining power P of the battery is obtained. If P<10%, the floor cleaning device in the third mode is adjusted to the first mode; if 10%≤P<20%, the floor cleaning device in the third mode is adjusted to the second mode.

[0126] In this way, when the battery power is low, the cleaning mode is adjusted to extend the battery life and ensure cleaning efficiency without changing the battery.

[0127] It should be noted that the above control method is only preferred and can be adjusted by those skilled in the art. For example, when P<10%, the floor cleaning device in the third mode can also be adjusted to the second mode. Alternatively, those skilled in the art can selectively omit this step.

[0128] In one embodiment, the floor cleaning device control method further includes obtaining an image of the position to be cleaned, specifically, obtaining the image of the position to be cleaned by a visual sensor; and determining the type of stain at the position to be cleaned based on the image. For example, the type of stain at the position to be cleaned is determined by identifying the image of the position to be cleaned.

[0129] It should be noted that the above method of determining the type of stain at the location to be cleaned is preferred, and those skilled in the art may also use other methods to determine the type of stain. The relevant methods have been described in the structural introduction of the above-mentioned floor cleaning equipment and will not be repeated here.

[0130] In one embodiment, the step of "obtaining the type of stain at the position to be cleaned" further includes: if the stain type acquisition fails, determining the stain type is the third stain type. In this way, if the stain type acquisition fails, the stain type is determined to be the third stain type, so that even if unidentifiable stains appear, effective cleaning can be performed to avoid incomplete cleaning.

[0131] Of course, the above steps are not necessary, and those skilled in the art may selectively omit the steps.

[0132] Combine the following Fig.14 , a possible implementation process of the present application is introduced.

[0133] like Fig.14 As shown, in one possible operation process:

[0134] S201, obtaining the stain type S of the location to be cleaned;

[0135] S202: If S∈the first stain type S1, the cleaning mode is the first mode.

[0136] S203, if S∈the second stain type S2, the cleaning mode is the second mode.

[0137] S204, if and The cleaning mode is the third mode, and then S205 is executed.

[0138] S205, obtaining the remaining power P of the battery.

[0139] S206: If P<10%, adjusting the floor cleaning device in the third mode to the first mode.

[0140] S207: If 10%≤P<20%, the floor cleaning device in the third mode is adjusted to the second mode.

[0141] S208: If 20% ≤ P, the cleaning mode is not adjusted.

[0142] It should be noted that although the detailed steps of the method of the present application are described in detail above, without departing from the basic principles of the present application, technical personnel in this field can combine, split and change the order of the above steps. The modified technical solution does not change the basic concept of the present application and therefore falls within the scope of protection of the present application.
