Description

Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular provides a method for controlling floor cleaning equipment. Background Art

[0002] In the application field of floor scrubbers, a heating mechanism is usually required to enhance the cleaning effect. There are some problems with the existing floor scrubber heating control methods, which lead to energy waste and poor cleaning effect.

[0003] The existing technology is based on manual adjustment of heating control. The operator needs to manually adjust the heating temperature according to the degree of dirtiness, but this method is prone to errors and inconsistencies. For areas with more serious dirtiness, higher heating temperatures may be required for effective cleaning, while some areas with less serious dirtiness can be cleaned with lower heating temperatures. The operator may not have enough experience or cannot accurately judge the heating temperature required for different degrees of dirtiness, resulting in reduced cleaning effect and possible waste of energy.

[0004] Therefore, a new technical solution is needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0054] 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.

[0055] 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.

[0056] like Figure 1-12 As shown, the floor cleaning device of the present application is described to solve the problem that the existing operator cannot accurately judge the heating temperature required for different degrees of dirt, 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, a return water component and a turbidity 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, the return water component is arranged on the upper side of the housing 4, and the turbidity detection component is arranged on the return water component and is configured to detect the turbidity of the liquid in the return water component.

[0057] 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. The return water component can draw back and store the water used for washing the floor, and the turbidity detection component is used to detect the turbidity of the liquid in the return water component, so as to control the opening or closing of the first heating component and the second heating component through the turbidity data.

[0058] 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 return water component, a turbidity detection component, a battery and a power detection component.

[0059] like Figure 9-12As 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The return water component includes a return water pipe and a sewage tank. The liquid used to clean the floor enters the sewage tank through the return water pipe. The sewage tank is connected to the handheld frame 6. The turbidity detection component includes a turbidity sensor; the turbidity sensor is arranged in the sewage tank, and the turbidity sensor uses the principle of light scattering to measure turbidity. Specifically, it emits light into the sewage tank and judges the turbidity of the liquid according to the degree of scattering of the light in the liquid. When there are particles in the liquid, the light will be scattered by these particles, causing the propagation path of the light to change, thereby reducing the intensity of the light. After receiving the intensity of the scattered light, the concentration of the particles in the liquid can be inferred based on the intensity of the scattered light.

[0069] It should be noted that the above-mentioned turbidity sensor is preferably set up, and the turbidity in the sewage tank can also be detected by other types of turbidity sensors. For example, an acoustic turbidity sensor uses the scattering and absorption characteristics of suspended particles encountered by sound waves when propagating in a liquid. The acoustic turbidity sensor emits sound wave pulses and measures the attenuation and signal changes during the propagation of the sound waves in the liquid. When there are particles in the liquid, the sound waves will interact with the particles, causing the sound waves to be scattered and absorbed. By measuring the changes in the propagation characteristics of the sound waves in the liquid, the particle concentration in the liquid can be determined.

[0070] It should also be further explained that the turbidity sensor can also be set in other positions. For example, the turbidity sensor can be set in the return pipe to detect the turbidity in the return pipe; or the return pipe can be fully or partially transparent, and the turbidity sensor can be placed on the outside of the transparent part of the return pipe to detect the turbidity in the return pipe.

[0071] 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.

[0072] 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.

[0073] 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 .

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Other possible implementations of the local surface cleaning device are described below.

[0082] 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. For example, the heating wire 51 and the heating element 52 are both located inside the roller brush body 1, and there are two heating wires 51, and one end of the two heating wires 51 is electrically connected to the two conductive rings 24 respectively. 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. Of course, the heating element 52 can also be constructed in other forms. For example, the heating element 52 can also be made of other materials that can generate heat, such as ceramic heating plates.

[0083] In an alternative implementation, the first conductive component and the second conductive component may also adopt other structures. The first conductive component includes a spring sheet 217 and a conductive block 218 , and the second conductive component includes a conductive ring 24 .

[0084] There are two conductive rings 24 , which are sleeved on the fixed base 214 and fixed to the fixed base 214 .

[0098] Refer to the following Fig.13 , the startup control method of the air conditioner of the present application is introduced.

[0099] like Fig.13 As shown, corresponding to the above-mentioned floor cleaning device, the floor cleaning device control method of the present application includes:

[0100] S101, obtaining turbidity data in the return water component; for example, obtaining turbidity data in the return water component through a turbidity sensor.

[0101] S103, determining the interval in which the turbidity data is located; for example, analyzing the turbidity data and dividing the turbidity data into corresponding intervals.

[0102] S105, determining a cleaning mode of the floor cleaning device based on the interval in which the turbidity data is located; for example, different intervals correspond to different cleaning modes, and the cleaning mode of the floor cleaning device is determined according to the different intervals in which the turbidity data is located.

[0103] S107, 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.

[0104] The control method of the floor cleaning equipment of the present application determines different cleaning modes according to different turbidity data, and turns on or off the first heating component and the second heating component. When the turbidity data in the return water component is high, it means that the cleaning position is more dirty at this time, and when the turbidity data in the return water component is low, it means that the cleaning position is less dirty at this time. It can heat according to the turbidity data adaptively according to different degrees of dirt, so that the cleaning effect of dirt is better.

[0105] The preferred implementation modes of the present application are introduced below.

[0106] In one embodiment, the cleaning mode of the present application includes a first mode, a second mode and a third mode.

[0107] 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.

[0108] 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. The bristles on the outside of the roller brush body can be heated at a higher temperature and directly act on the dirt, which has a better cleaning effect on some stains.

[0109] 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.

[0110] 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, so that the cleaning effect of general dirt on the ground is better. When the required temperature rises, the corresponding rotation speed and flow rate decrease. The reduction in flow rate can improve the heating effect, and the reduction in rotation speed can prevent heat dissipation, so that the effect of cleaning serious dirt is better.

[0111] 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.

[0112] In one embodiment, the step of "determining the cleaning mode of the floor cleaning device based on the interval in which the turbidity data is located" further includes: if the turbidity data is less than or equal to a first preset threshold, determining that the cleaning mode of the floor cleaning device is the first mode; if the turbidity data is greater than the first preset threshold and less than or equal to a second preset threshold, determining that the cleaning mode of the floor cleaning device is the second mode; if the turbidity data is greater than the second preset threshold, determining that the cleaning mode of the floor cleaning device is the third mode. The second preset threshold is greater than the first preset threshold.

[0113] It should be noted that 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 in the roller brush body is 1.2: 1. Here, the rotation speed of the front roller brush body is used as the basis for explanation.

[0114] Specifically, the present application takes the turbidity data as F, the first preset threshold value as 5 mg / L, the second preset threshold value as 20 mg / L, the first rotation speed as 450 rpm, the second rotation speed as 400 rpm, the third rotation speed as 350 rpm, the first flow rate as 25 ml / min, the second flow rate as 20 ml / min, and the third flow rate as 15 ml / min as an example. If the turbidity data obtained is less than or equal to 5 mg / L, it proves that there is less dirt at this location, then the cleaning mode is determined to be the first mode, at which time the first heating component and the second heating component are both controlled to be turned off, the rotation speed of the roller brush body is the first rotation speed, i.e. 450 rpm, and the flow rate of the pump body is the first flow rate, i.e. 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 turbidity data obtained is greater than 5 mg / L and less than or equal to 20 mg / L, it proves that the dirtiness of the location is at a medium level, then 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, 20 ml / min. In this way, for stains that are generally difficult to clean, the use of medium heating temperature, rotation speed and flow rate can achieve effective cleaning of the ground, maximize the use of electricity, and avoid wasting electricity. If the turbidity data obtained is greater than 20 mg / L, it proves that the location is more dirty, then 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, 15 ml / min. In this way, a higher heating temperature is used to clean more dirt and achieve a good cleaning effect.

[0115] Of course, the specific values ​​of the first preset threshold, the second preset threshold, the first speed, the second speed, the third speed, the first flow rate, the second flow rate and the third flow rate 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.

[0116] 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.

[0117] In one embodiment, after the step of “determining the cleaning mode of the floor cleaning device based on the interval in which the turbidity data is located”, the control method further includes:

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] In one implementation, the floor cleaning device further includes a buzzer fixedly connected to the handheld part frame. After the step of "obtaining the turbidity data in the water return assembly", the control method further includes: if the turbidity data is greater than the third preset threshold, the buzzer emits a dirt alarm; otherwise, the buzzer is turned off. For example, when the turbidity data is greater than the third preset threshold, the buzzer emits a dirt alarm to remind the user to timely discover the uncleaned stains, so as to achieve the purpose of thoroughly cleaning the floor. And the third preset threshold is greater than the second preset threshold. For example, the third preset threshold can be 30 mg / L. When the turbidity data is relatively large, the buzzer reminds the user to pay attention, enabling the user to timely discover the uncleaned stains, and thus repeat the cleaning to achieve the purpose of thoroughly cleaning the floor.

[0123] It should be noted that the setting of the buzzer is not necessary. Those skilled in the art can adjust it according to the actual application situation, or other devices that can remind the user to pay attention can also be adopted, such as by means of lights, displaying text on the screen, etc. At the same time, those skilled in the art can also adjust the value of the third preset threshold according to the actual situation. Of course, those skilled in the art can selectively omit this step.

[0124] The following combines Fig.14 , and introduces a possible implementation process of the present application.

[0125] As Fig.14 shown, in a possible operation process:

[0126] S201, obtain the turbidity data F in the sewage tank;

[0127] S202, if F ≤ 5 mg / L, the cleaning mode is the first mode.

[0128] S203, if 5 mg / L < F ≤ 20 mg / L, the cleaning mode is the second mode.

[0129] S204, if F > 20 mg / L, the cleaning mode is the third mode, and then execute S205 and S209.

[0130] S205, obtain the remaining power P of the battery.

[0131] S206, if P < 10%, adjust the floor cleaning device in the third mode to the first mode.

[0132] S207, if 10% ≤ P < 20%, adjust the floor cleaning device in the third mode to the second mode.

[0133] S208, if 20% ≤ P, do not adjust the cleaning mode.

[0134] S209, if F>30mg / L, the buzzer alarms.

[0135] 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.
