DETAILED DESCRIPTION

[0034] In the following description, numerous specific details are given to provide a thorough understanding of the application. However, it will be apparent that the application can be practiced without one or more of the specific details. In other instances, well-known techniques are not described in detail in order to avoid obscuring the application.

[0035] ​It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0036] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0037] The self-cleaning method for cleaning equipment provided in this application can be applied to cleaning equipment. In order to clearly describe the self-cleaning method of the cleaning equipment of the present invention, the cleaning equipment provided in the second aspect of the present invention will be described in detail below.

[0038] like Figures 1 to 5 As shown, this embodiment of the invention provides a cleaning device, including a body 10 and a cleaning component 60 rotatably connected to the body 10. The body 10 is also provided with a dirt collection component and a cleaning liquid delivery component. The cleaning component includes a housing 601, and at least one cleaning roller 602 and a drive mechanism are provided in the accommodating space of the housing 601. The drive mechanism is tractively connected to each cleaning roller 602. The drive mechanism is used to drive at least one of the cleaning rollers 602 to rotate. The rotation direction can be forward or reverse. For example, in self-cleaning mode, drying mode or air-drying mode, it can drive at least one of the cleaning rollers 602 to rotate in reverse.

[0039] The cleaning equipment can be handheld cleaning devices, such as handheld floor scrubbers. We will take handheld cleaning devices as an example for a detailed explanation. Specifically, for example... Figure 1 As shown, the main body 10 has a slender structure, and the cleaning component 60 is located at the lower part of the main body 10 and is rotatably connected to the main body 10. During the cleaning operation, the main body 10 is tilted relative to the cleaning component 60. This utilizes the downward pressure generated by the weight of the main body 10 to make the cleaning component 60 fit more closely to the surface to be cleaned, and also makes it easier for the user to push the cleaning component 60 with the main body 10, requiring less effort. When storing the cleaning equipment, the main body 10 is perpendicular to the cleaning component 60, thereby reducing the space occupied by the cleaning equipment.

[0040] like Figure 2 ,Figure 3 , Figure 4 and Figure 5 As shown, specifically, the cleaning roller 602 includes a rotating roller 6024 and bristles 6023 disposed on the outer periphery of the rotating roller 6024. Specifically, the drive mechanism is connected to the rotating roller 6024, thereby enabling the drive mechanism to drive the cleaning roller 602 to rotate forward or in reverse. Each cleaning roller 602 is equipped with a corresponding scraping mechanism 603, that is, the number of scraping mechanisms 603 is the same as the number of cleaning rollers 602 and corresponds one-to-one; of course, the cleaning roller 602 may also be equipped with two or more scraping mechanisms 603, and the number of scraping mechanisms 603 configured in each cleaning roller 602 can be set according to the specific structure and functional requirements of the cleaning assembly 60.

[0041] like Figure 1 and Figure 3 As shown, the dirt recovery assembly includes a recovery bin 20, a vacuum blower 40, and a suction pipe 70. The recovery bin 20 and the vacuum blower 40 are mounted on the main body 10, and the outlet of the suction pipe 70 is connected to the recovery bin 20, with the vacuum blower 40 in fluid communication with the recovery bin 20. The vacuum blower 40 creates negative pressure within the suction pipe 70 to draw dirt from the surface to be cleaned and from the scraping mechanism 603 into the recovery bin 20. The suction pipe 70 can be a rigid pipe extending along a specific path, or a flexible pipe whose path can be changed, depending on the type and structural design of the cleaning equipment.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning fluid delivery assembly includes a cleaning fluid tank 30, a water supply pipe 50, and a water outlet module 605. The cleaning fluid tank 30 is mounted on the machine body 10 and is connected to the water outlet module 605 via the water supply pipe 50. The water outlet module 605 is used to spray the cleaning fluid from the cleaning fluid tank 30 onto the cleaning roller 602 through the water supply pipe 50. The water supply pipe can be a rigid pipe extending along a path or a flexible hose whose path can be changed, depending on the type and structural design of the cleaning equipment.

[0043] Furthermore, a water pump is also installed on the water supply pipeline 50. The water pump can increase the flow rate of the cleaning liquid and shorten the time it takes for the cleaning liquid to flow to the water outlet module 605, thereby improving the working efficiency of the handheld cleaning equipment.

[0044] Furthermore, the machine body is equipped with a controller that can be implemented using various application-specific integrated circuits (ASICs) (140SiC), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPG140), microcontrollers, microprocessors, or other electronic components. The controller is used to switch between various operating modes and, in each operating mode, to control the cleaning roller 602, water pump, and drive unit to perform corresponding actions. The controller is mounted on the machine body 10, which also has a cleaning switch electrically connected to the controller and a touch display. The touch display can show multiple operation buttons and current information such as the water level, operating mode, and battery level. Users can select the operating mode via the touch display. The operating modes include at least self-cleaning mode and sweeping mode, and may also include other modes such as drying or air-drying modes. Specifically, the self-cleaning mode refers to the mode in which the cleaning equipment automatically cleans the cleaning rollers and suction ducts after completing the cleaning operation; the sweeping mode refers to the mode in which the cleaning equipment cleans the surface to be cleaned; the drying mode refers to the mode in which the damp cleaning rollers are heated and dried; and the air-drying mode refers to the mode in which the damp cleaning rollers are dried by blowing air.

[0045] Furthermore, the device body 10 is also equipped with a reminder component connected to the controller. The reminder component includes a speaker and a memory that pre-stores several voice audios.

[0046] It is understood that the forward rotation of the cleaning roller 602 in this application refers to the circumferential rotation of the contact point between the cleaning roller 602 and the surface to be cleaned in the direction that gradually approaches the air inlet of the suction pipe 70. See details below. Figure 2 , Figure 5 , Figure 6 and Figure 7 The solid arrow in the text indicates the direction; reversing the cleaning roller 602 means that the contact point between the cleaning roller 602 and the surface to be cleaned rotates circumferentially in a direction that first moves away from the air inlet and then gradually moves closer to it, which is the opposite of the forward rotation. See details. Figure 2 , Figure 5 , Figure 6 and Figure 7 The direction of the dotted arrow in the figure. The rotation duration and speed of the cleaning roller 602 in both forward and reverse directions can be set by the user through the touch screen, or can be set before the cleaning equipment leaves the factory. In this embodiment, the rotation duration and speed of the cleaning roller 602 in both forward and reverse directions are not strictly limited.

[0047] Specifically, when using cleaning equipment, such as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, in the case that the bristles 6023 of the cleaning roller 602 are not sprayed with the cleaning liquid, the bristles 6023 of the cleaning roller 602 are in a dry state, that is, the bristles 6023 are in a straight and fluffy state, so that the outer diameter of the cleaning roller 602 is in a maximum state, that is, the length of R1 in Figure 2 , Figure 5 , Figure 6 and Figure 7 , and in the case that the bristles 6023 of the cleaning roller 602 are sprayed with the cleaning liquid, the bristles 6023 of the cleaning roller 602 are wetted, and through the friction between the bristles 6023 and the surface to be cleaned, the bristles 6023 are in a flat state, that is, most or even all of the bristles 6023 adhere to the rotating roller 6024, that is, the outer diameter of the cleaning roller 602 is the length of R2 in Figure 2 and Figure 5 , so that the outer diameter of the cleaning roller 602 is reduced, thereby reducing the tightness of the contact between the scraping mechanism 603 and the bristles 6023, and further reducing the scraping force of the scraping mechanism 603 on the bristles 6023, so that part of the dirt attached to the bristles 6023 is not scraped off by the scraping mechanism 603. These dirt are brought into the accommodation space where the cleaning roller 602 is located due to the forward rotation of the cleaning roller 602, and due to the centrifugal force generated by the forward rotation of the cleaning roller 602 or the dirt scraping other components in the accommodation space, such as the water outlet module 605, resulting in the dirt remaining in the accommodation space.

[0048] In this embodiment, in order to clean the dirt in the accommodation space, when the self-cleaning device enters the self-cleaning mode, the controller controls the driving mechanism to drive at least one cleaning roller 602 to reverse, so that the bristles 6023 of the reversed cleaning roller 602 are erected through the scraping force of the scraping mechanism 603, so that the bristles 6023 are in a straight and fluffy state, so that the outer diameter of the cleaning roller 602 is increased, so that the outer diameter of the cleaning roller 602 tends to be in a maximum state, that is, the length of R1 in Figure 2 , Figure 5 , Figure 6 and Figure 7 , thereby increasing the tightness and friction of the bristles 6023 with the dirt remaining in the accommodation space, so that the dirt remaining in the accommodation space can be attached to the bristles 6023. In addition, with the continuous reverse rotation of the cleaning roller 602, the cleaning roller 602 continuously cleans the accommodation space, and through the blocking of the scraping mechanism 603 and the scraping force of the scraping mechanism 603 on the bristles 6023, the dirt on the bristles 6023 is accumulated in the gap between the cleaning roller 602 and the scraping mechanism 603, and with the increase of the reverse rotation time of the cleaning roller 602, more and more dirt is accumulated, forming a dirt ball.

[0049] Therefore, according to the cleaning device provided by the embodiment of the present invention, during the reversal of the cleaning roller 602, the scraping force of the scraping mechanism 603 causes the bristles of the cleaning roller 602 to stand up, thereby increasing the contact tightness and friction between the bristles 6023 and the dirt remaining in the accommodating space. This allows the dirt remaining in the accommodating space to adhere to the bristles 6023, thereby cleaning the dirt in the accommodating space where the cleaning roller 602 is located. This avoids the problem that dirt remaining in the accommodating space is prone to mold and odor if not cleaned for a long time, which would affect the environment and user health; and it also eliminates the need for manual cleaning by the user, improving the user experience.

[0050] In addition, after the bristles 6023 of the cleaning roller stand up, the surface area of ​​the outer periphery bristles 6023 of the cleaning roller 602 in contact with the air increases, which is beneficial to the subsequent drying of the cleaning roller. Therefore, in the air drying mode or dry drying mode of the cleaning equipment, the drying speed can be accelerated by reversing the cleaning roller 602 before or during the drying process.

[0051] The dirt can be dust, small impurities (such as flocculent matter, mud, and paper scraps), or hair, or it can be liquid. The cleaning solution can be any of water, detergent, or a mixture of water and detergent. The surface to be cleaned is the surface that the cleaning equipment needs to clean during operation, such as the ground, floor, glass, etc., but is not limited to these. Furthermore, this embodiment does not limit the specific location of the scraping mechanism 603; the scraping mechanism 603 can be positioned within the accommodating space to scrape the cleaning roller 602, and the number of scraping mechanisms 603 is not limited. Similarly, this embodiment does not limit the specific location of the water outlet module 605; the water outlet module 605 can be positioned within the accommodating space to spray the cleaning solution onto the cleaning roller 602, and the number of water outlet modules 605 is not limited. Within a controllable scraping force range, the higher the hardness, the longer the length, and the greater the density of the bristles 6023, the better the self-cleaning effect.

[0052] Furthermore, such as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the scraping mechanism 603 is set at a certain angle to the outer periphery of the cleaning roller 602, and the scraping mechanism 603 and the outer periphery of the cleaning roller 602 are in interference contact. The scraping mechanism 603 includes at least one scraper, and the specific number of it can be set by the operator according to actual needs. This embodiment does not impose a strict limitation.

[0053] The scraping mechanism 603 is set at a certain angle to the outer periphery of the cleaning roller 602. This increases the resistance of the scraping mechanism 603 to the cleaning roller 602, thereby improving the scraping effect on the cleaning roller 602. The interference contact ensures that the scraper bar is in close contact with the outer periphery of the cleaning roller 602, which can better remove stains or cleaning liquid adhering to the outer periphery of the cleaning roller 602, further improving the cleaning effect on the cleaning roller.

[0054] In some implementations, the scraping mechanism 603 is located above the cleaning roller. Specifically, when the scraping mechanism 603 is disposed on the outer periphery of the cleaning roller 602 to scrape off the cleaning liquid or stains remaining on the outer periphery of the cleaning roller 602, the scraping mechanism 603 is disposed near the inlet of the suction pipe 70 to scrape off the cleaning liquid or stains remaining on the cleaning roller 602 before suction, or to scrape and suction substantially simultaneously, thereby improving the cleanliness of the cleaning roller 602.

[0055] The following is a detailed description of the number and rotation method of the cleaning rollers 602 in the above embodiments.

[0056] In some embodiments, such as Figure 2 As shown, there is one cleaning roller 602. Before or after the cleaning equipment enters the self-cleaning mode, drying mode or air-drying mode, the controller controls the drive mechanism to drive the cleaning roller 602 to reverse.

[0057] In other embodiments, there is one or more cleaning rollers 602. Before or after the cleaning equipment enters the self-cleaning mode, drying mode or air-drying mode, the controller controls the drive mechanism to drive at least one of the cleaning rollers 602. This can be either partial or complete reversal of the cleaning rollers 602.

[0058] An exemplary case is given in detail with two cleaning rollers 602.

[0059] There are two cleaning rollers 602, namely a first cleaning roller 6021 and a second cleaning roller 6022; the drive mechanism is used to drive the first cleaning roller 6021 and / or the second cleaning roller 6022 to reverse.

[0060] In one implementation, such as Figure 5 As shown, after the cleaning equipment enters the self-cleaning mode, drying mode or air-drying mode, the drive mechanism can drive the first cleaning roller 6021 and the second cleaning roller 6022 to reverse, so as to use the first cleaning roller 6021 and the second cleaning roller 6022 to clean the accommodating space at the same time.

[0061] In another implementation, such as Figure 6 and Figure 7As shown, after the cleaning device enters the self-cleaning mode, the drying mode or the air-drying mode, the driving mechanism can also drive only the first cleaning roller 6021 or the second cleaning roller 6022 to reverse, i.e., the first cleaning roller 6021 reverses and the second cleaning roller 6022 rotates forward, or the first cleaning roller 6021 rotates forward and the second cleaning roller 6022 reverses. This rotating mode is suitable for the case where the accommodation space around one cleaning roller 602 still has dirt, while the accommodation space around the other cleaning roller 602 is relatively clean, thereby avoiding that all cleaning rollers 602 continuously clean the accommodation space where they are located, and consuming more power.

[0062] Further, in order to take out the dirt cleaned from the accommodation space, the cleaning roller 602 can also be driven by the driving mechanism to rotate forward after reversing, so that the dirt accumulated in the cleaning roller 602 and the dirt removal mechanism 603 rotates forward with the cleaning roller 602 during the forward rotation of the cleaning roller 602, and the dirt removal mechanism 603 is used to scrape the dirt accumulated in the cleaning roller 602, thereby achieving the purpose of cleaning the dirt in the accommodation space.

[0063] In order to improve the cleaning effect, the dust collector fan 40 and / or the water spraying pump can be started during the forward or reverse rotation of the cleaning roller 602, and the wind power of the dust collector fan 40 and / or the water spraying amount of the water spraying pump can be adjusted.

[0064] For example, during the reverse rotation of the cleaning roller 602, the controller controls the dust collector fan 40 to start working, so that the cleaning liquid on the cleaning roller 602 can be sucked, and a large amount of cleaning liquid will flow through the suction pipeline 70 of the cleaning device, thereby achieving the purpose of flushing the suction pipeline 70. The dust collector fan 40 works at a higher power, which improves the speed of sucking the cleaning liquid, thereby not only increasing the speed of cleaning the suction pipeline 70, but also improving the drying speed of the cleaning roller 602, so that the bristles 6023 of the cleaning roller 602 are more easily erected, and the bristles 6023 are more closely contacted with the dirt in the accommodation space, the friction force is also increased, thereby improving the cleaning effect and efficiency of the cleaning roller 602 on the accommodation space.

[0065] In the process of rotating the cleaning roller 602 forward, the controller controls the water spraying pump to work at the maximum flow, and uses the dirt scraping mechanism 603 to scrape the dirt gathered by the cleaning roller 602, so as to clean the cleaning roller 602. The bristles 6023 again absorb a large amount of cleaning liquid, so that the dirt after being soaked is more easily scraped off by the dirt scraping mechanism 603, which greatly improves the scraping effect of the dirt on the bristles 6023. And in this process, the water spraying pump continuously sprays cleaning liquid to the cleaning roller 602 at the maximum flow, which can further improve the soaking effect of the dirt, so that the dirt is more easily scraped off. And in the process of rotating the cleaning roller 602 forward, a part of the cleaning liquid will be thrown out, which will reduce the amount of cleaning liquid on the cleaning roller 602. Therefore, the continuous spraying of the water spraying pump is also a supplement of the cleaning liquid to the cleaning roller 602. And the dirt scraped off by the dirt scraping mechanism 603 can be sucked into the recycling box 20 by the dust collection fan 40.

[0066] Of course, in the process of rotating the cleaning roller 602 forward or reversely, the dust collection fan 40 and the water spraying pump can also adopt other cooperation modes, which are not strictly limited in the application.

[0067] In the application, the driving mechanism can adopt different structures according to different rotating modes.

[0068] The first structure: the driving mechanism includes two transmission assemblies; one of the transmission assemblies is in transmission connection with the first cleaning roller 6021, and the other transmission assembly is in transmission connection with the second cleaning roller 6022.

[0069] In this structure, the rotation of the first cleaning roller 6021 and the second cleaning roller 6022 is respectively driven by the corresponding transmission assembly, and this structure is suitable for all the rotating modes described above, that is, the first cleaning roller 6021 and the second cleaning roller 6022 can be reversely rotated at the same time, or the first cleaning roller 6021 is rotated forward and the second cleaning roller 6022 is reversely rotated, or the first cleaning roller 6021 is reversely rotated and the second cleaning roller 6022 is rotated forward. Therefore, the rotating direction of the first cleaning roller 6021 and the second cleaning roller 6022 is not limited by the transmission assembly, thereby improving the flexibility of the rotation of the first cleaning roller 6021 and the second cleaning roller 6022.

[0070] The second structure: the driving mechanism includes one transmission assembly; the first cleaning roller 6021 and the second cleaning roller 6022 are respectively in transmission connection with the transmission assembly; and the transmission assembly is used to reversely rotate the first cleaning roller 6021 and the second cleaning roller 6022.

[0071] In the structure, the number of the transmission assembly is one, that is, the first cleaning roller 6021 and the second cleaning roller 6022 share one transmission assembly, which can drive the first cleaning roller 6021 and the second cleaning roller 6022 to rotate reversely at the same time, so that the number of the transmission assembly is reduced, and the cost is reduced.

[0072] Specifically, the transmission mechanism is a gear box.

[0073] Among them, at least two gears meshing with each other are arranged in the gear box, one of which is connected with the corresponding motor as a main gear, and the other is connected with the rotation of the corresponding cleaning roller 602 as a driven gear, so that the main gear is driven to rotate, and the driven gear is driven to rotate together, so that the corresponding cleaning roller 602 is driven to rotate.

[0074] Further, the outer box of the gear box can be made of sound-absorbing material to reduce the noise generated during the operation of the gear box.

[0075] The driving mechanism further comprises a motor and a motor driving circuit connected with the motor, and the motor driving circuit comprises an H-bridge circuit.

[0076] The H-bridge circuit can reverse the voltage or current at the output end to make the motor rotate forward or reversely; then the motor rotating forward or reversely drives the transmission assembly to rotate, thereby driving the corresponding cleaning roller 602 to rotate, and realizing the forward rotation and reverse rotation of the cleaning roller 602.

[0077] In some embodiments, the dirt recycling assembly comprises a recycling box 20, a suction pipeline 70 and a dust suction fan 40; the air outlet of the suction pipeline 70 is connected with the recycling box 20, the air inlet of the suction pipeline 70 is arranged above the cleaning roller 602, and the dust suction fan 40 is in fluid communication with the recycling box 20; the dust suction fan 40 and the cleaning liquid distribution assembly are used for cleaning the cleaning roller 602 and / or the suction pipeline 70.

[0078] The cleaning operation of the cleaning device mainly relies on the sweeping and mopping of the cleaning roller 602 and the suction and collection of the dirt by the suction pipeline 70, so the cleaning roller 602 and the suction pipeline 70 need to be cleaned. In the embodiment, the cleaning roller 602 and / or the suction pipeline 70 can be cleaned by the dust suction fan 40 and the cleaning liquid distribution assembly, and the working modes of the dust suction fan 40 and the cleaning liquid distribution assembly can be freely combined according to the actual cleaning requirements, which is not strictly limited in the application.

[0079] Further, the dust suction fan 40 and the cleaning liquid distribution assembly are also used for pre-cleaning the cleaning roller 602 in the self-cleaning mode.

[0080] Before the cleaning roller 602 is reversed in the above embodiment, the cleaning roller 602 can also be cleaned by the suction fan 40 and the cleaning liquid distribution assembly, so that the cleaning of the accommodation space is performed when the cleaning roller 602 is relatively clean, thereby improving the cleaning effect.

[0081] To further illustrate the self-cleaning process of the entire cleaning device, as shown in Figure 8 the following will be described in detail with respect to a self-cleaning process, which specifically includes the following steps:

[0082] Step S101: receiving or generating a self-cleaning instruction.

[0083] In some embodiments, the user inputs the self-cleaning instruction by himself through the touch display screen or operation button on the cleaning device, or inputs the self-cleaning instruction through the application program of the terminal device and sends it to the cleaning device, so that the cleaning device can receive the self-cleaning instruction.

[0084] In another embodiment, the cleaning device can automatically generate a cleaning instruction when the cleaning device is placed on the cleaning pile, so that the user does not need to input the cleaning instruction by himself, thereby improving the user experience.

[0085] In yet another embodiment, the cleaning device posture is converted to determine whether the cleaning device has completed the cleaning operation, so that the self-cleaning instruction is received when the cleaning device is converted from a tilted state to an upright state, that is, the cleaning device has completed the cleaning operation, thereby eliminating the need for the user to input the cleaning instruction by himself, thereby improving the user experience.

[0086] Step S102: in response to the self-cleaning instruction, controlling the cleaning device to enter a self-cleaning mode.

[0087] The self-cleaning mode can achieve the purpose of automatically cleaning the cleaning device without manual cleaning by the user, which can improve the intelligent degree of the cleaning device while reasonably reducing the use cost of the entire machine, and is conducive to improving the user experience. Further, at the same time when the self-cleaning mode starts, the controller controls the loudspeaker to broadcast the voice of "starting self-cleaning" to enable the user to understand that the self-cleaning mode switching is successful.

[0088] Step S103: performing a pre-cleaning step of the cleaning roller 602.

[0089] This step pre-cleans the cleaning roller 602, thereby cleaning the dirt attached to the cleaning roller 602 during the cleaning operation, thereby improving the cleanliness of the cleaning roller 602, and thereby improving the cleaning effect of the cleaning roller 602 on the accommodation space during the subsequent reversing process of the cleaning roller 602.

[0090] Specifically, as shown in Figure 9 Step S103 specifically includes:

[0091] Step S1031: Control the driving part to drive the cleaning roller 602 to rotate forward, and control the suction fan 40 to work at the first power.

[0092] In this step, the cleaning liquid delivery assembly does not spray cleaning liquid to the cleaning roller 602, that is, the water spraying pump does not work. With the cleaning roller 602 rotating forward, the dirt attached to the cleaning roller 602 during the cleaning operation is scraped off by the dirt scraping mechanism 603, and the scraped dirt is concentrated near the air inlet of the suction pipeline 70. Thus, the scraped dirt is sucked into the recovery tank 20 by the negative pressure generated by the suction fan 40 in the suction pipeline 70, thereby realizing the cleaning of the cleaning roller 602 and the recovery of the dirt.

[0093] The first power of the suction fan 40 can be set by the user through the touch screen, or can be set before the cleaning device is shipped. The size of the first power is not strictly limited in the embodiment. In specific application, the first power is set to be small, so that the dirt can be sucked into the recovery tank 20, thereby reducing the power consumption of the suction fan 40.

[0094] Step S1032: Control the driving part and the suction fan 40 to stop working, and control the water spraying pump to work at the maximum flow.

[0095] In this step, the water spraying pump works at the maximum flow, so that the cleaning liquid is sprayed to the stationary cleaning roller 602. The bristles 6023 of the cleaning roller 602 absorb a large amount of cleaning liquid, so that the dirt attached to the bristles 6023 is soaked by the cleaning liquid, so as to achieve the purpose of cleaning the cleaning roller 602. In the process of spraying the cleaning liquid, the suction fan 40 is controlled to stop working, so as to avoid that the sprayed cleaning liquid is sucked into the recovery tank 20 from the air inlet of the suction passage, thereby reducing the amount of cleaning liquid sprayed to the bristles 6023.

[0096] The water spraying pump works at the maximum flow, which can increase the spraying time, shorten the soaking time of the bristles 6023, and improve the cleaning efficiency. Specifically, the spraying time of the cleaning liquid is usually about 5s.

[0097] Further, when the step is executed, the controller controls the loudspeaker to broadcast the voice of “cleaning the cleaning roller 602”, so that the user can understand the progress of the self-cleaning.

[0098] Step S1033: Control the driving part to drive the cleaning roller 602 to rotate forward, and control the water spraying pump to continue to work at the maximum flow.

[0099] In the process of rotating the cleaning roller 602 forward, the dirt attached to the bristles 6023 of the cleaning roller 602 is scraped off by the dirt scraping mechanism 603. Based on the fact that a large amount of cleaning liquid is absorbed by the bristles 6023 in step S2022, the dirt after being soaked is more easily scraped off by the dirt scraping mechanism 603, which greatly improves the scraping effect of the dirt on the bristles 6023. In this process, the water spraying pump continuously sprays cleaning liquid to the cleaning roller 602 at the maximum flow rate, which can further improve the soaking effect of the dirt, so that the dirt is more easily scraped off. In the process of rotating the cleaning roller 602 forward, a part of the cleaning liquid is thrown out, which reduces the amount of cleaning liquid on the cleaning roller 602. Therefore, the continuous spraying of the water spraying pump is also a supplement of the cleaning liquid for the cleaning roller 602. In addition, in this process, the dust suction fan 40 is always stopped, so as to avoid the sprayed cleaning liquid being sucked into the recovery box 20 through the air inlet of the suction channel, which reduces the amount of cleaning liquid sprayed on the bristles 6023.

[0100] In this step, in the process of rotating the cleaning roller 602 forward, the dirt scraping mechanism 603 and the sprayed cleaning liquid can make the cleaning roller 602 have a better cleaning effect.

[0101] Step S1034: controlling the water spraying pump to stop working, and the driving part to continue rotating the cleaning roller 602 forward.

[0102] In the case that the water spraying pump stops working, that is, stops spraying cleaning liquid to the cleaning roller 602, the cleaning roller 602 continues to rotate forward, so as to throw out part of the cleaning liquid on the cleaning roller 602, thereby improving the dryness of the cleaning roller 602.

[0103] The length of time for rotating the cleaning roller 602 forward can be set by the user through the touch screen, or can be set before the cleaning equipment is shipped. The length of time for rotating the cleaning roller 602 forward is not strictly limited in this embodiment. In specific applications, in order to improve the drying effect of the cleaning roller 602, the length of time for rotating the cleaning roller 602 forward in this step is relatively long, about 15s.

[0104] In this step, in the process of rotating the cleaning roller 602 forward, the dirt scraping mechanism 603 and the sprayed cleaning liquid can make the cleaning roller 602 have a better cleaning effect.

[0105] Further, steps S101 to S104 can be steps for pre-cleaning the cleaning roller 602 in the self-cleaning mode, and of course can also be steps for cleaning the cleaning roller 602 alone, which is not strictly limited in this application.

[0106] For cleaning the suction pipeline 70, the controller controls the driving part to drive the cleaning roller 602 to rotate, and the dust suction fan 40 and the water spraying pump to work.

[0107] In this step, the cleaning roller 602 is soaked by the water spraying pump, and then the cleaning liquid on the cleaning roller 602 is sucked into the recycling tank 20 through the suction pipeline 70 by controlling the suction fan 40, so that the suction pipeline 70 is cleaned during the flow of the cleaning liquid through the suction pipeline 70. The flowing gas formed by the suction pipeline 70 also accelerates the evaporation speed of the cleaning liquid on the cleaning roller 602, so that the drying speed of the cleaning roller 602 is further accelerated.

[0108] Step S104: The driving part drives the cleaning roller 602 to reverse, so that the bristles 6023 of the cleaning roller 602 are erected by the scraping force of the scraping mechanism.

[0109] This step can refer to the description of the reverse rotation of the cleaning roller 602 in the above embodiment, and will not be repeated here.

[0110] Step S105: The driving part drives the cleaning roller 602 to rotate forward, so that the dirt on the cleaning roller 602 is scraped off by the scraping mechanism.

[0111] This step can refer to the description of the forward rotation of the cleaning roller 602 in the above embodiment, and will not be repeated here.

[0112] Further, when this step is performed, the controller controls the loudspeaker to broadcast the voice of "cleaning the cleaning roller 602", so that the user knows the progress of the self-cleaning.

[0113] Step S106: Repeat steps S104-S105 several times.

[0114] The steps S104-S105 are repeated several times, so that the accommodation space can be repeatedly cleaned, thereby improving the cleaning effect of the accommodation space, and the suction pipeline 70 can also be cleaned multiple times during the cleaning of the accommodation space, thereby improving the cleaning effect of the suction pipeline 70.

[0115] The number of repetitions can be set before the cleaning device is shipped, and the duration of the forward rotation of the cleaning roller 602 is not strictly limited in this embodiment. In specific applications, the number of repetitions can be set to 2-5 times.

[0116] Step S107: Perform the deep cleaning step.

[0117] When the cleaning device is working, there will be a lot of dirt on the cleaning roller 602, and the suction pipeline 70 will suck the dirt on the cleaning roller 602 and the dirt on the surface to be cleaned into the recycling tank 20, and there will be a lot of dirt in the suction pipeline 70. Therefore, this step further cleans the cleaning roller 602 and the suction pipeline 70 to ensure good self-cleaning effect.

[0118] Further, when performing the step, the controller controls the speaker to play a voice of "deep cleaning" to make the user know the progress of the self-cleaning.

[0119] Specifically, as shown in Figure 10 the step S107 specifically includes:

[0120] The step S1071: control the driving part to drive the cleaning roller 602 to reverse, the water spraying pump to stop working, and the dirt detection part to periodically detect the cleaning roller 602.

[0121] During the reversing of the cleaning roller 602, the controller controls the water spraying pump to stop working, so as to suspend the spraying of the cleaning liquid to the cleaning roller 602, so as to improve the accuracy of the subsequent cleaning detection and detection of the cleaning roller 602.

[0122] Specifically, the dirt detection part is arranged on the shell 601 of the cleaning assembly 60, and the dirt detection part is used to detect whether there is dirt remaining on the cleaning roller 602, and the detection result is transmitted to the controller, so that the controller performs corresponding control operation based on the detection result.

[0123] In specific application, the dirt detection part can adopt a light sensor or a reflective light sensor, the dirt detection part senses the light reflection speed on the bristles 6023 of the cleaning roller 602, and transmits the light reflection speed to the controller, so as to identify the light reflection speed by the controller, so as to judge whether there is dirt remaining on the cleaning roller 602.

[0124] In the embodiment, the dirt detection part is controlled to periodically detect, so as to not only ensure the detection of different areas of the cleaning roller 602, improve the accuracy of the detection, but also reduce the power consumption of the dirt detection part.

[0125] It is worth noting that the interval time cannot be an integer multiple of the time used for one revolution of the cleaning roller 602, so as to avoid the repeated detection of the same part of the cleaning roller 602 by the dirt detection part, and cause a larger error in the detection result.

[0126] The step S1072: based on the detection result of the dirt detection part, judge whether there is dirt remaining on the cleaning roller 602, if yes, execute the step S1073; if no, execute the step S1074.

[0127] The light reflection speed and the material type are stored in the memory. The controller finds the material type corresponding to the detected light reflection speed, and then determines whether the material type is the same as the material type of the bristles 6023. If it is determined that the material type is different from the material type of the bristles 6023, for example, the material type is hair, it is determined that there is dirt on the cleaning roller 602. If it is determined that the material type is the same as the material type of the bristles 6023, it is determined that there is no dirt on the cleaning roller 602. The memory can be arranged on the machine body 10 of the cleaning device.

[0128] Step S1073: prolong the reverse rotation time of the cleaning roller 602.

[0129] In the case of determining that there is dirt on the cleaning roller 602, the cleaning roller 602 is controlled to continue to reverse rotation for a certain time, so that the cleaning roller 602 continues to be scraped by the dirt scraping mechanism 603 to scrape off the dirt and make the dirt accumulate between the dirt scraping mechanism 603 and the cleaning roller 602. This can ensure that the cleaning roller 602 is cleaned thoroughly, thereby improving the self-cleaning effect of the cleaning roller 602.

[0130] Step S1074: do not prolong the reverse rotation time of the cleaning roller 602.

[0131] In the case of determining that there is no dirt on the cleaning roller 602, the cleaning roller 602 does not need to continue to reverse rotation, so as to reduce the power consumption of the cleaning device.

[0132] Step S1075: control the driving part to drive the cleaning roller 602 to alternately rotate in the forward and reverse directions, and control the dust suction fan 40 to work at the first power.

[0133] In this step, the suction pipeline 70 is cleaned again and the cleaning roller 602 is dried by controlling the dust suction fan 40 and the cleaning roller 602 in cooperation. Specifically, during the operation of the dust suction fan 40, the cleaning roller 602 is also controlled to rotate reversely and alternately, that is, the cleaning roller 602 reversely rotates for a period of time and then rotates forwardly for a period of time, so that the dirt accumulated in the gap between the dirt scraping mechanism 603 and the cleaning roller 602 in step S2093 is brought to the air inlet of the suction pipeline 70 during the forward rotation of the cleaning roller 602, and then the dirt is scraped by the dirt scraping mechanism 603 and collected into the recovery tank 20 by the suction pipeline 70. By changing the rotation direction, the effect of repeatedly rubbing the bristles 6023 by the cleaning roller 602 is improved, the cleanliness of the bristles is improved, and the cleaning liquid brushed off from the cleaning roller 602 can also be sucked into the recovery tank 20 by the suction pipeline 70 to clean the suction pipeline 70 again when the cleaning liquid flows through the suction pipeline 70, thereby improving the self-cleaning effect of the suction pipeline 70. The flowing gas formed by the suction pipeline 70 also accelerates the evaporation speed of the cleaning liquid on the cleaning roller 602, thereby further accelerating the drying speed of the cleaning roller 602.

[0134] Further, before this step is performed, that is, before the dust suction fan 40 is started, the controller can control the loudspeaker to broadcast the voice of “cleaning pipeline” to make the user understand the progress of self-cleaning and remind the user that the start of the dust suction fan 40 will bring a certain sound.

[0135] Step S108: controlling the driving part to drive the cleaning roller 602 to rotate forwardly and the dust suction fan 40 to work at the second power.

[0136] In this step, part of the cleaning liquid can be brushed out during the forward rotation of the cleaning roller 602, thereby accelerating the drying speed of the cleaning roller 602, and the dust suction fan 40 is controlled to work at a greater power, thereby improving the suction force to improve the suction ability of the cleaning liquid, so that the brushed-out cleaning liquid can be quickly recovered, and the air flow speed can also be greatly improved, thereby accelerating the evaporation speed of the cleaning liquid of the cleaning roller 602, so that the drying speed of the cleaning roller 602 is faster.

[0137] Of course, the above is only an exemplary self-cleaning process, and other cooperation modes among the cleaning roller 602, the dust suction fan 40 and the water spraying pump can also be used to realize the self-cleaning process in actual application, and the present embodiment is not strictly limited.
