Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a control method for a surface cleaning device. Background Technology

[0002] Currently, surface cleaning devices such as floor scrubbers are widely used. A surface cleaning device includes a cleaning machine and a base; the cleaning machine includes a pivotally connected floor brush and a body, with rotatable cleaning components on the brush; while cleaning the surface to be cleaned, the cleaning components rotate to wipe away the dirt adhering to the surface. After cleaning, a large amount of dirt adheres to the cleaning components, which need to be cleaned promptly to ensure smooth operation for the next cleaning session. After cleaning, the cleaning components are in a damp state; to prevent bacterial growth, they need to be dried promptly.

[0003] In existing technology, floor brushes contain a scraping component. When drying the cleaning component, the cleaning component and the scraping component are in an interference fit. Although this fit can remove water during the rotation of the cleaning component, the constant pressure during rotation causes the bristles of the cleaning component to lie flat on the surface. Furthermore, the longer the cleaning component rotates and / or the longer it is used, the more flattened the bristles become. When the bristles lie flat, the wet bristles stick together, which is not conducive to drying the base of the bristles and affects drying efficiency. At the same time, after drying, the cleaning component has poor fluffiness, affecting the cleaning effect on the surface. Summary of the Invention

[0004] The purpose of this application is to provide a control method for a surface cleaning device, which alleviates the problem of the cleaning part collapsing and reducing the drying efficiency during the drying process due to the scraping of the scraping part, and proposes a drying method that can both improve the drying efficiency and make the brush bristles fluffy after drying.

[0005] The surface cleaning device in this application includes a cleaning machine and a base. A drying component is provided on the base or the cleaning machine. The cleaning machine has a floor brush, and the floor brush is provided with a scraper and a cleaning component. The cleaning component has a first state in which it is at a first distance from the scraper and a second state in which it is at a second distance from the scraper, wherein the first distance is less than the second distance.

[0006] The control method for the surface cleaning device includes a drying step, which includes at least:

[0007] Control the operation of the drying component and control the cleaning component to be in the second state.

[0008] In one embodiment, the drying step further includes the cleaning component being in a first state, and the drying step includes the cleaning component switching from the first state to a second state, or the cleaning component switching between the first state and the second state.

[0009] In one embodiment, before the cleaning component switches from the first state to the second state, the cleaning component is controlled to rotate in the opposite direction of the first state for a preset time before switching to the second state.

[0010] In one embodiment, the drying step further includes detecting the degree of dryness of the cleaning component, and controlling the cleaning component to operate in a second state when the degree of dryness of the cleaning component reaches a preset value.

[0011] In one embodiment, during the drying step, the rotational speed of the cleaning component is V1 when it is in the first state and V2 when it is in the second state, wherein V2 is greater than V1.

[0012] In one embodiment, when the cleaning component is in the second state, the cleaning component is controlled to rotate at a rotation speed V3 for a first preset time, and then the cleaning component is controlled to rotate at a rotation speed V4 for a second preset time; or, the cleaning component is controlled to rotate at a rotation speed V4 for a third preset time, and then the cleaning component is controlled to rotate at a rotation speed V3 for a fourth preset time; wherein, the rotation speed V3 is less than the rotation speed V4.

[0013] In one embodiment, the cleaning component is in a second state, and the cleaning component is controlled to rotate forward or backward.

[0014] In one embodiment, the control method further includes a spin-drying step, and the surface cleaning device further includes a suction fan for generating suction force. The spin-drying step includes at least: controlling the cleaning component to be in a first state and controlling the cleaning component to rotate at a speed V5, and controlling the suction fan to run; after the surface cleaning device completes the spin-drying step, it enters a drying step.

[0015] In one embodiment, the spin-drying step further includes controlling the cleaning component to alternately be in a first state and a second state.

[0016] In one embodiment, the floor brush is further provided with a suction port for receiving dirt from the cleaning component. The cleaning component in the first state moves horizontally forward to bring it into a second state, and a drying gap is formed between the cleaning component in the second state and the suction port.

[0017] In this application, during the drying process of the cleaning component, the relative positions of the cleaning component and the scraping component are adjusted by moving the cleaning component at an appropriate time. At least the interference fit depth between the cleaning component and the scraping component is reduced, or the interference fit between the cleaning component and the scraping component is released, i.e., a clearance fit is achieved. This alleviates the phenomenon of bristle flattening that occurs in the cleaning component during the drying process, facilitates the drying of the bristle roots, and improves the drying efficiency. At the same time, it also improves the fluffiness of the cleaning component after drying, ensuring the cleaning effect on the surface to be cleaned. Attached Figure Description

Detailed Implementation

[0032] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0033] Similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Example 1:

[0035] This embodiment provides a surface cleaning device 1, such as... Figure 1 As shown, the surface cleaning device 1 in this embodiment includes a cleaning machine 10 and a base 20. The cleaning machine 10 is used to clean the ground surface waiting to be cleaned, and the base 20 is used to perform maintenance operations such as self-cleaning, drying and charging of the cleaning machine 10.

[0036] like Figure 2 As shown, the cleaning machine 10 includes a control unit, a pivotally connected floor brush 120, and a body 110. (As...) Figure 3 As shown, the floor brush 120 is equipped with a cleaning component 123, a drive motor (not shown in the figure), and a driving component (not shown in the figure). The drive motor is connected to the control unit and the cleaning component 123, and is used to drive the cleaning component 123 to rotate under the control of the control unit. The driving component is connected to the control unit, and is used to drive the cleaning component 123 to cause relative displacement between the cleaning component 123 and the scraping component 124 on the floor brush 120 under the control of the control unit. For example, the cleaning component 123 can be any cleaning tool that can be used to wipe the floor or other surfaces waiting to be cleaned, such as a single roller brush, a double roller brush, or a tracked cleaning cloth.

[0037] In one implementation of this embodiment, during the drying process, the cleaning component 123 can undergo relative displacement with the scraping component 124 under the drive of the driving component. This relative displacement can be achieved by the cleaning component 123 moving horizontally under the action of the driving component to reduce or eliminate the interference fit between the cleaning component 123 and the scraping component 124. Alternatively, the cleaning component 123 can move obliquely upwards in an inclined direction under the action of the driving component. Alternatively, the relative position of the cleaning component 123 and the floor brush 120 remains unchanged, while the scraping component 124 moves horizontally or rotates to reduce or eliminate the interference fit between the cleaning component 123 and the scraping component 124.

[0038] The floor brush 120 is also provided with a housing, which is located above the cleaning component 123 and at least partially covers the cleaning component 123.

[0039] The floor brush 120 is also provided with a liquid supply component 125, which is located on one side of the cleaning component 123. As an optional solution in this embodiment, the liquid supply component 125 is located above the scraping component 124 and is used to supply liquid to the cleaning component 123 at a certain flow rate under the control of the control unit.

[0040] The floor brush 120 is also equipped with a suction port 122, which is located on one side of the cleaning component 123. The body 110 is equipped with a suction pipe (not shown in the figure), a wastewater tank 111 and a suction fan 112. The suction pipe is connected to the suction port 122 and the wastewater tank 111. The suction fan 112 is connected to the wastewater tank 111 and is connected to the control unit. The suction fan 112 is used to suck dirt into the wastewater tank 111 through the suction port 122 and the suction pipe under the control of the control unit.

[0041] The floor brush 120 is also provided with a scraper 124, which is located on one side of the cleaning component 123. For example, the floor brush 120 may have only one scraper 124, which is a straight ordinary scraper bar used to scrape the dirt on the cleaning component 123, or the scraper 124 is a comb-tooth scraper bar with serrations.

[0042] like Figure 3As shown, the floor brush 120 may also be equipped with two scraping elements 124, namely a first scraping element 1241 and a second scraping element 1242. The first scraping element 1241 is a straight, ordinary scraping strip used to scrape dirt off the cleaning element 123, and the second scraping element 1242 is a comb-toothed scraping strip used to remove hair from the cleaning element 123. The first scraping element 1241 and the second scraping element 1242 may be approximately on the same plane in the longitudinal direction, with the first scraping element 1241 located above the second scraping element 1242. Alternatively, the first scraping element 1241 may be located below the second scraping element 1242. As one implementation of this embodiment, the first scraping element 1241 and the second scraping element 1242 may have the same interference fit with the cleaning element 123. Alternatively, the interference fit between the first scraping component 1241 and the cleaning component 123 is greater than the interference fit between the second scraping component 1242 and the cleaning component 123; or, the interference fit between the first scraping component 1241 and the cleaning component 123 is less than the interference fit between the second scraping component 1242 and the cleaning component 123.

[0043] The surface cleaning device 1 in this embodiment also includes a drying component, which is disposed on the base 20 or the cleaning machine 10. The drying component is used to generate airflow and / or heat to dry the cleaning component 123. In this embodiment, the structure of the drying component is explained by taking an airflow generating component disposed on the base 20 as an example. The base 20 is provided with an air outlet 220. The drying component is connected to the air outlet 220 and to the control unit. Under the control of the control unit, the drying component is used to discharge airflow to the cleaning component 123 through the air outlet 220 to dry the cleaning component 123. Specifically, the drying component can be a drying fan, which, under the control of the control unit, discharges airflow to the cleaning component 123 through the air outlet 220 to dry the cleaning component 123; or, the drying component can include a drying fan and a heating wire, with the heating wire located in the gas delivery path of the drying fan, the drying fan discharging airflow under the control of the control unit, and the heating wire heating the airflow under the control of the control unit, and the heated airflow being discharged onto the cleaning component 123 through the air outlet 220 to dry the cleaning component 123.

[0044] Those skilled in the art will appreciate that the drying assembly could also be a suction fan 112 mounted on the body 110 that generates an airflow from the cleaning component 123 toward the suction fan 112 during the drying process. Alternatively, the drying assembly could be a heating element mounted on the base 20 for drying the cleaning component 123.

[0045] Generally, when the surface cleaning device 1 is cleaning the ground surface waiting to be cleaned, the cleaning component 123 and the scraping component 124 are in an interference fit state; specifically, during normal cleaning, the cleaning component 123 and the scraping component 124 are in an interference fit state with a first interference amount; at the same time, the control unit controls the suction fan 112 to run the drive motor to drive the cleaning component 123 to rotate; during the rotation of the cleaning component 123, the control unit controls the liquid supply component 125 to supply liquid to the cleaning component 123 at a certain flow rate to keep the cleaning component 123 in a wet state. The moistened cleaning component 123 generates physical friction with the surface to be cleaned during rotation, removing dirt from the surface. During the dirt removal process, dirt may adhere to the cleaning component 123 or the surface to be cleaned. The scraping component 124 scrapes the cleaning component 123 during its rotation, removing some of the dirt. The suction fan 112, while operating, draws the dirt from the surface to be cleaned and the dirt scraped off from the cleaning component 123 into the wastewater tank 111 through the suction port 122 and the suction pipe. The surface to be cleaned is continuously cleaned in this manner until the cleaning work is completed.

[0046] After cleaning, a large amount of dirt will adhere to the cleaning component 123. To ensure the smooth progress of the next cleaning operation, the cleaning component 123 needs to be cleaned in a timely manner. After cleaning, the cleaning component 123 is in a moist state. To avoid the growth of bacteria, the cleaning component 123 needs to be dried in a timely manner.

[0047] In the prior art, the floor brush 120 is equipped with a scraper 124. When drying the cleaning component 123, the cleaning component 123 and the scraper 124 are in an interference fit. Although this fit can remove water during the rotation of the cleaning component 123, the constant pressure on the cleaning component 123 during rotation causes the bristles of the cleaning component 123 to lie flat on the surface. The longer the rotation time and / or the longer the usage time of the cleaning component 123, the more flattened the bristles become. When the bristles of the cleaning component 123 lie flat, the wet bristles stick together, which is not conducive to drying the roots of the bristles of the cleaning component 123, thus affecting the drying efficiency. At the same time, after drying, the cleaning component 123 has poor fluffiness, which affects the cleaning effect on the surface to be cleaned.

[0048] To address the aforementioned problems, this embodiment provides a control method for the surface cleaning device 1. This method is executed by the aforementioned control unit, and its working principle is explained in detail below:

[0049] like Figure 4 As shown, the control method of the surface cleaning device 1 in this embodiment includes the following drying step S1:

[0050] Drying step S1: Control the operation of the drying component and control the cleaning component 123 to be in the second state.

[0051] In this embodiment, the cleaning component 123 has a first state where it is at a first distance from the scraping component 124, and a second state where it is at a second distance from the scraping component 124, where the first distance is less than the second distance. That is, when the cleaning component 123 is in the second state, it is farther from the scraping component 124. The following relationship can be derived: when the cleaning component 123 is in the first state, it has an interference fit with the scraping component 124; when the cleaning component 123 is in the second state, it can have an interference fit with the scraping component 124, but the interference fit depth is lower than that in the first state; or, the cleaning component 123 can release the interference fit with the scraping component 124, i.e., a clearance fit. Those skilled in the art will understand that when there are two scraping parts 124, if the cleaning part 123 is in the first state, the cleaning part 123 is in an interference fit with the two scraping parts 124, and the depth of the interference fit can be equal or different; when there are two scraping parts 124, if the cleaning part 123 is in the second state, the cleaning part 123 can be in an interference fit with both scraping parts 124 at the same time, or the cleaning part 123 can be in an interference fit with only one of the scraping parts 124, but the depth of the interference fit is less than the depth of the interference fit between the cleaning part 123 and the scraping part 124 in the first state, or the cleaning part 123 can be released from the interference fit with both scraping parts 124 at the same time.

[0052] When the control unit executes step S1, it controls the drying assembly to operate and simultaneously controls the cleaning component 123 to be in the second state; specifically, if the cleaning component 123 is in the second state when step S1 is executed, the control unit does not perform any operation; Figure 3 As shown, if the cleaning component 123 is in the first state, the driving component drives the cleaning component 123 to move away from the scraping component 124 and the suction port 122, as shown. Figure 5 As shown, after moving to a certain position, the cleaning component 123 is in a second state, controlling the cleaning component 123 to stop moving. After the drying assembly operates, airflow is discharged onto the cleaning component 123 through the air outlet 220 on the base 20 to dry the cleaning component 123. Those skilled in the art will understand that the drying assembly can be turned on during or before performing step S1. In this step S1, the control unit can control the cleaning component 123 to rotate continuously, rotate intermittently, or control the cleaning component 123 not to rotate.

[0053] First, when the cleaning component 123 is in the first state, it is in an interference fit with the scraping component 124. This fit causes the bristles of the cleaning component 123 to easily flatten on the cleaning component 123. Specifically, the bristles at the interference fit between the cleaning component 123 and the scraping component 124 are prone to flattening. During the rotation of the cleaning component 123, it is constantly squeezed and flattened by the scraping component 124. The time and centrifugal force required for the cleaning component 123 to rotate without the scraping component 124 are insufficient for it to fully recover its fluffy state. Therefore, when the cleaning component 123 is always in the first state for drying, although the water in the cleaning component 123 can be quickly removed by the scraping of the scraping component 124, excessive scraping will cause the bristles to flatten. Therefore, the cleaning component 123 should not always be in the first state during the drying process. It should also include a second state in which the interference fit between the cleaning component 123 and the scraping component 124 is small or non-interference fit. By placing the cleaning component 123 in the second state, the interference fit depth between the cleaning component 123 and the scraping component 124 is reduced, or the interference fit between the cleaning component 123 and the scraping component 124 is released, which alleviates the phenomenon of bristle flattening that occurs in the cleaning component 123 during the drying process, making it easier to dry the bristle roots and improving the drying efficiency; at the same time, it also increases the fluffiness of the cleaning component 123 after drying, ensuring the cleaning effect on the surface to be cleaned.

[0054] Secondly, such as Figure 3 and Figure 5 As shown, compared to the first state, when the cleaning component 123 is in the second state, the cleaning component 123 is closer to the air outlet 220 located on the front side wall of the cleaning tank 210. The airflow from the air outlet 220 to the cleaning component 123 is greater and the heat is higher, which improves the drying efficiency of the cleaning component 123.

[0055] Thirdly, such as Figure 3 As shown, when the cleaning component 123 is in the first state, the cleaning component 123 and the scraping component 124 are in interference contact. At this time, the surface of the cleaning component 123 and the surface of the cleaning tank 210 form a first air duct 1271, and the airflow discharged from the air outlet can only follow the... Figure 3 The arrow in the image indicates that the airflow passes through the first air duct 1271 to dry the cleaned part 123; however, as Figure 5 As shown, when the cleaning component 123 is in the second state, and the interference fit between the cleaning component 123 and the scraper 124 is released to form a clearance, a first air duct 1271 is formed between the surface of the cleaning component 123 and the surface of the cleaning tank 210, and a second air duct 1272 is formed between the cleaning component 123 and the inner surface of the cover 121, the scraper 124, and the liquid supply component 125. The airflow discharged from the outlet can simultaneously follow the... Figure 5The airflow, as indicated by the arrows, flows through the first air duct 1271 and the second air duct 1272 to dry the cleaning component 123. This demonstrates that in step S1, by placing the cleaning component 123 in the second state, bidirectional airflow is achieved, allowing the airflow to fully envelop the entire cleaning component 123 and improving drying efficiency. Furthermore, as the airflow passes through the second air duct 1272, it also dries the inner surface of the cover 121, the scraper 124, and the liquid supply component 125, resulting in even better drying.

[0056] Fourthly, such as Figure 3 As shown, when the cleaning component 123 is in the first state, because the cover 121 is a straight surface parallel to the rotation axis of the cleaning component 123, or the cover 121 is a concentric arc surface concentrically arranged with the cleaning component 123, the width S1 of the second air duct 1272 in the direction from the cleaning component 123 to the scraping component 124 is the same; however, as Figure 5 As shown, when the cleaning component 123 is in the second state, the width S1 of the second air duct 1272 in the direction from the cleaning component 123 to the scraping component 124 gradually widens. This allows the airflow to enter the first air duct 1271 at a faster speed when drying the cleaning component 123, thereby improving the drying efficiency of the cleaning component 123.

[0057] Fifthly, such as Figure 5 As shown, when the cleaning component 123 is in the second state, the gap between the cleaning component 123 and the suction port 122 increases, forming a drying gap. At this time, when the cleaning component 123 and the scraping component 124 are in an interference fit, the airflow flows to the drying gap through the first air duct 1271. When the cleaning component 123 and the scraping component 124 are released from the interference fit, the airflow flows to the drying gap through both the first air duct 1271 and the second air duct 1272. After flowing to the drying gap, the airflow can stay in the drying gap for a period of time to dry the suction port 122 and its surroundings, resulting in a good drying effect.

[0058] Sixthly, the base 20 typically performs a self-cleaning operation on the cleaning machine 10 first, cleaning the cleaning component 123 and the suction pipe through the self-cleaning operation; after the self-cleaning operation is completed, a drying operation is performed to dry the cleaning component 123 and the suction pipe through the drying operation. However, in practice, the suction fan 112 is in a closed state when the drying operation is performed, and residual liquid in the suction pipe may flow directly down through the suction port 122. Therefore, in the drying step S1, the cleaning component 123 is placed in a second state away from the suction port 122, so that the liquid flowing out of the suction port 122 flows into the cleaning tank 210 instead of flowing onto the cleaning component 123. At the same time, when the drying airflow flows through the first air duct 1271 through the cleaning tank 210, the residual liquid flowing into the cleaning tank 210 can be evaporated. This setting fully ensures the drying efficiency of the cleaning component 123.

[0059] As one implementation of this embodiment, the cleaning component 123 moves away from the suction port 122 and the scraping component 124 by moving the cleaning component 123 horizontally under the action of the driving component, thereby moving the cleaning component 123 away from the suction port 122 and the scraping component 124, thereby adjusting the gap between the cleaning component 123 and the suction port 122 and the scraping component 124.

[0060] As one implementation of this embodiment, the driving component can be a motor mounted on the floor brush 120. Two motors are directly or indirectly mounted on both sides of the driving component. When the cleaning component 123 is switched from the first state to the second state, the two motors can jointly drive the cleaning component 123 to move away from the scraper 124 and the suction port 122. When the cleaning component 123 is switched from the second state to the first state, the two motors can jointly drive the cleaning component 123 to move closer to the scraper 124 and the suction port 122.

[0061] As one implementation of this embodiment, in step S1, the control unit can control the operation of the suction fan 112. When the suction fan 112 is running, the airflow flows through the first air duct 1271 and / or the second air duct 1272 at a faster speed, further improving the drying efficiency of the cleaning component 123. Simultaneously, when the suction fan 112 is running, it can also guide the airflow into the suction pipe to dry the suction pipe. Optionally, during the drying process of the cleaning component 123, the suction fan 112 can be continuously or intermittently operated, or selectively operated according to the drying needs and / or requirements of the cleaning component 123. Optionally, during the drying process, the operating power of the suction fan 112 can be consistent with that of the surface cleaning device 1 when cleaning the floor, or it can operate at a higher power to improve drying efficiency, or it can operate at a lower power to reduce environmental noise, or it can operate at varying power according to the drying requirements of the cleaning component 123.

[0062] In one implementation of this embodiment, in step S1, the control unit can adjust the airflow speed of the drying component and the heating power of the heating wire according to the dryness of the cleaning component 123; when the suction fan 112 is running, the operating power of the suction fan 112 can also be adjusted according to the dryness of the cleaning component 123. The wetter the cleaning component 123, the drying component is controlled to blow air at a faster speed and / or the heating wire is controlled to operate at a higher heating power and / or the suction fan 112 is controlled to operate at a higher operating power.

[0063] Example 2:

[0064] Based on the above embodiments, this embodiment provides a control method for a surface cleaning device 1, which includes a drying step S1. In the drying step S1 of this embodiment, the cleaning component 123 can be in a first state in addition to being in a second state.

[0065] Specifically, in the drying step S1 of this embodiment, the control unit can control the cleaning component 123 to switch from a first state to a second state, and after successful switching, keep the cleaning component 123 in the second state. In this embodiment, the cleaning component 123 is first placed in the first state, so that the cleaning component 123 and the scraper 124 are in interference contact, so that the scraper 124 can scrape off most of the moisture on the cleaning component 123 during the rotation of the cleaning component 123; after the cleaning component 123 has been running in the first state for a period of time, the cleaning component 123 is switched to the second state, so that the drying component can dry the remaining moisture on the cleaning component 123 during the rotation of the cleaning component 123, thereby improving the drying efficiency of the cleaning component 123. Those skilled in the art will understand that the timing of the cleaning component 123 switching from the first state to the second state during the drying process can be a fixed time set by the product factory or the user, or any reasonable condition such as automatic switching when the weight or humidity of the cleaning component 123 reaches a preset value after monitoring.

[0066] Optionally, in the drying step S1 of this embodiment, the control unit can detect the degree of dryness of the cleaning component 123. When the degree of dryness of the cleaning component 123 reaches a preset value, the control unit can control the cleaning component 123 to operate in a second state. Specifically, in the drying step S1, while drying the cleaning component 123, the control unit can determine the degree of dryness of the cleaning component 123 by detecting the drive motor current, drive motor voltage, drive motor power, humidity of the cleaning component 123, weight of the cleaning component 123, resistance of the cleaning component 123, etc. As the drying process proceeds, if the degree of dryness of the cleaning component 123 reaches the preset value and the moisture content of the cleaning component 123 is low, the cleaning component 123 needs to be rotated quickly to ensure drying efficiency. However, when the moisture content of the cleaning component 123 is low, if the cleaning component 123 is in the first state with an interference fit with the scraper 124, the resistance is large when the cleaning component 123 rotates rapidly, and the load on the drive motor surges, resulting in excessive output current and potential electrical hazards. Therefore, when the moisture content of the cleaning component 123 is low, if the first state of the cleaning component 123 cannot support its rapid rotation, it is detrimental to ensuring the drying efficiency of the cleaning component 123. To address this, in the drying step S1 of this embodiment, when the drying degree of the cleaning component 123 reaches a preset value, the cleaning component 123 is controlled to operate in the second state, reducing the interference fit depth between the cleaning component 123 and the scraper 124, or releasing the interference fit between the cleaning component 123 and the scraper 124. This reduces the rotational resistance of the cleaning component 123 and the load on the drive motor, allowing the output current of the drive motor to remain at a normal level, preventing overheating of the drive motor, and enabling the drive motor to support the rapid rotation of the cleaning component 123, thus fully ensuring the drying efficiency of the cleaning component 123.

[0067] Optionally, in the drying step S1 of this embodiment, when the cleaning component 123 is in the first state, the control unit can control the cleaning component 123 to rotate at a first rotational speed V1; when the cleaning component 123 is in the second state, the control unit can control the cleaning component 123 to rotate at a second rotational speed V2; wherein, the second rotational speed V2 is greater than the first rotational speed V1. When the cleaning component 123 is in the first state, it is in an interference fit with the scraping component 124. When the rotational speed of the cleaning component 123 is too high, the load on the drive motor is too large and the output current is too large, which can easily cause overheating. By making the cleaning component 123 rotate at a low speed, the load and output current of the drive motor are reduced, and the overheating of the drive motor is avoided, thus protecting the drive motor. When the cleaning component 123 is in the second state, the interference fit depth with the scraping component 124 is low, or there is no interference fit at all. When the speed of the cleaning component 123 is high, the load on the drive motor is also small and it is not easy to generate heat. Therefore, when the cleaning component 123 is in the second state, the cleaning component 123 is controlled to rotate at a high speed, so that the drive motor can run normally while the excess water is thrown out, ensuring the drying efficiency of the cleaning component 123.

[0068] Example 3:

[0069] Optionally, in the drying step S1 of this embodiment, the control unit can also control the cleaning component 123 to switch between a first state and a second state. Those skilled in the art will understand that when controlling the cleaning component 123 to switch between the first and second states, the initial state of the cleaning component 123 can be the first state, or the initial state of the cleaning component 123 can be the second state. The cleaning component 123 rotates in the first state, scraping off residual moisture. The cleaning component 123, having had its moisture scraped off, moves to the second state to rotate, reducing or eliminating the squeezing force of the scraper 124 and ensuring sufficient contact with the drying airflow, while utilizing the centrifugal force generated during rotation to fluff the cleaning component 123. After sufficient contact with the drying airflow for a period of time, it switches from the second state back to the first state to remove moisture again, and this cycle repeats. This solves both the problem of excessive moisture content in the cleaning component 123 during the drying process, which results in low drying efficiency relying solely on the drying assembly, and the problem of the scraper 124 continuously squeezing and flattening the bristles of the cleaning component 123.

[0070] Furthermore, by switching the cleaning component 123 between the first and second states, the cleaning component 123 vibrates during its displacement, causing some of the water on it to be shaken off; especially when the cleaning component 123 vibrates and rotates simultaneously, even more excess water can be shaken off. Simultaneously, when the cleaning component 123 switches between the first and second states, water on the cleaning component 123 can be removed through a combination of scraping and drying, thus improving the drying efficiency of the cleaning component 123.

[0071] Example 4:

[0072] Based on the above embodiments, this embodiment provides a control method for a surface cleaning device 1. The method includes a drying step S1. In the drying step S1 of this embodiment, at least the cleaning component 123 is switched from a first state to a second state, or the cleaning component 123 is switched between a first state and a second state.

[0073] Furthermore, the drying step also includes: before the control unit switches the cleaning component 123 from the first state to the second state, the control unit can control the cleaning component 123 to rotate in the reverse direction of the first state for a preset time before switching to the second state. Specifically, before the cleaning component 123 switches from the first state to the second state, the cleaning component 123 is in the first state with an interference fit with the scraping component 124, and then the control unit controls the cleaning component 123 to... Figure 3The direction shown in P2 is reversed. During the rotation, the scraping component 124 lifts the bristles on the cleaning component 123, exposing the bristle roots. When the cleaning component 123 rotates in the reverse direction for a preset time, the control unit switches the cleaning component 123 to the second state. After the switch is completed, the drying component dries the cleaning component 123. At this time, because the bristle roots of the cleaning component 123 are exposed, the entire bristle and its roots of the cleaning component 123 can be effectively dried, resulting in high drying efficiency and better drying effect. Those skilled in the art will understand that after switching to the second state, the control unit can control the cleaning component 123 to rotate continuously, rotate intermittently, or control the cleaning component 123 not to rotate.

[0074] Example 5:

[0075] Based on the above embodiments, this embodiment provides a control method for a surface cleaning device 1. The method includes a drying step S1. In the drying step S1 of this embodiment, if the cleaning component 123 is in a second state, the control unit can control the cleaning component 123 to rotate at a third rotation speed V3 for a first preset time. Then, the control unit can control the cleaning component 123 to rotate at a fourth rotation speed V4 for a second preset time. The third rotation speed V3 is less than the fourth rotation speed V4. This method allows the cleaning component 123 to rotate slowly first, gradually drying each area of ​​its surface. Then, the cleaning component 123 rotates rapidly to re-dry any areas that were not fully dried, ultimately achieving uniform and thorough drying of the entire cleaning component 123, ensuring a good drying effect and preventing any missed areas from drying.

[0076] Optionally, in the drying step S1 of this embodiment, if the cleaning component 123 is in the second state, the control unit can control the cleaning component 123 to rotate at a fourth rotation speed V4 for a third preset time, and then the control unit can control the cleaning component 123 to rotate at a third rotation speed V3 for a fourth preset time. The third rotation speed V3 is less than the fourth rotation speed V4. This method allows the cleaning component 123 to rotate rapidly first, quickly drying the entire surface of the cleaning component 123 and removing most of the moisture; then, the cleaning component 123 rotates slowly to dry the remaining moisture, improving drying efficiency.

[0077] Example 6:

[0078] Based on the above embodiments, this embodiment provides a control method for a surface cleaning device 1, the method including a drying step S1: controlling the operation of the drying component and controlling the cleaning component 123 to be in a second state.

[0079] Optionally, the base 20 for placing the surface cleaning device 1 is an open-type control cleaning component 123, which is used in step S1 according to... Figure 3The direction indicated by P1 is a positive rotation. For example... Figure 3 and Figure 5 As shown, the base 20 is open, meaning that when the surface cleaning device 1 is placed on the base 20, the cleaning component 123 is partially exposed to the air. Rotating the cleaning component 123 clockwise allows cool air from outside the base 20 and airflow from the outlet 220 to enter the first air duct 1271 and the second air duct 1272, improving the drying efficiency of the cleaning component 123.

[0080] Optionally, the base 20 for placing the surface cleaning device 1 is sealed, and the cleaning control component 123 is controlled according to the following in step S1: Figure 3 The direction shown in P2 is reversed. Those skilled in the art will understand that the sealed base 20 mentioned here includes fully sealed base 20 and non-fully sealed base 20. That is, the sealing mentioned here does not mean that the base 20 can completely seal the peripheral area of ​​the floor brush 120 or form a completely sealed vacuum in the suction area. Rather, it simply refers to a structure that partially covers the edges of the base 20 and the floor brush 120 by providing sealing structures such as soft rubber or baffles on the base 20, reducing the open space between the floor brush 120 and the base 20. Figure 6 and Figure 7 As shown, when the base 20 is fully sealed, a connector 126 is provided on the base 20. The connector 126 can shield the portion of the cleaning component 123 that is exposed to the air, reducing the contact area between the cleaning component 123 placed on the base 20 and the outside air. At this time, the control unit controls the cleaning component 123 to proceed according to... Figure 6 When the direction shown in P2 is reversed, the airflow output from the air outlet 220 can stay in the first air duct 1271 and the second air duct 1272 for a longer time to dry the cleaning component 123, thereby improving the drying efficiency of the cleaning component 123.

[0081] Example 7:

[0082] Based on the above embodiments, this embodiment provides a control method for the surface cleaning device 1, such as... Figure 8 As shown, the method includes a spin-drying step S0 and a drying step S1:

[0083] Spin-drying step S0: Control the cleaning component 123 to be in the first state and control the cleaning component 123 to rotate at the fifth rotation speed V5, and control the suction fan 112 to run.

[0084] In this step, the control unit controls the cleaning component 123 to be in the first state, so that the cleaning component 123 abuts against the scraping component 124, and controls the cleaning component 123 to rotate. During the rotation of the cleaning component 123, the scraping component 124 can scrape off most of the water on the cleaning component 123. At the same time, after the suction fan 112 is running, it absorbs the water scraped off the cleaning component 123 into the wastewater tank 111. After the spin-drying step S0 is completed, the control unit can control the surface cleaning device 1 to perform the following drying step S1.

[0085] Drying step S1: Control the operation of the drying component and control the cleaning component 123 to be in the second state.

[0086] In this step, the control unit will control the drying assembly to dry the cleaning component 123. For the specific implementation method, please refer to the above embodiment, which will not be repeated here.

[0087] In this embodiment, the moisture on the cleaning component 123 is removed by a combination of spin drying and drying, which ensures the drying effect and improves the drying efficiency of the cleaning component 123.

[0088] Optionally, the rotation speed of the cleaning component 123 in the spin-drying step S0 is greater than that in the drying step S1. This allows more water to be removed in the spin-drying step S0, further improving the drying efficiency of the cleaning component 123.

[0089] Optionally, in the aforementioned spin-drying step S0, the control unit can control the cleaning component 123 to alternately be in the first state and the second state. If the drying component is only turned on to dry the cleaning component 123 when the spin-drying stage begins, the pre-cooling of the hot air output by the drying component will form water droplets that adhere to the cover 121. By switching the cleaning component 123 between the first state and the second state in the spin-drying step S0, a certain amount of vibration can be generated, which is more conducive to the spin-drying process. At the same time, during the state switching process, the cover 121 can be slightly vibrated, and the water droplets adhering to the cover 121 can be shaken off during the vibration.

[0090] Optionally, after completing the drying step S1, the control unit can control the cleaning component 123 to return to the first state, and after returning to the first state, control the cleaning component 123 to proceed according to... Figure 3 Rotating the brush in the opposite direction as shown in P2 will lift the bristles, ensuring the suction power of the cleaning component 123.

[0091] Example 8:

[0092] This embodiment proposes a connection method for a movable cleaning component 123 on a floor brush 120, based on the above embodiments.

[0093] like Figure 9As shown, in this embodiment, the cleaning component 123 has a receiving cavity, and the drive motor 1233 is disposed in the receiving cavity; the cleaning component 123 has a first end face and a second end face disposed opposite to each other, a first connecting rod 1232 is provided on the first end face, and a second connecting rod 1231 is provided on the second end face.

[0094] like Figure 9 , Figure 10 as well as Figure 11 As shown, the floor brush 120 has a first base 128 and a first connector 129. The first base 128 has a first end 12811, and the first end 12811 is provided with an open first semi-circular groove 1281. The first connector 129 is provided with an open second semi-circular groove 1291. When the first connector 129 is connected to the first base 128, the first semi-circular groove 1281 and the second semi-circular groove 1291 are connected to form a first mounting groove 1292. A first slider 1283 is provided in the first mounting groove 1292, and the first slider 1283 is connected to the first connecting rod 1232. The first base 128 is provided with a first driving member 1285, a first worm gear 1284 and a first transmission rod 1282; the first worm gear 1284 has a first inner hole 12841, and the output end of the first driving member 1285 is disposed in the first inner hole 12841; the first transmission rod 1282 has a first output end 12822 and a first mating hole 12821, the first worm gear 1284 is disposed in the first mating hole 12821, and the first output end 12822 is connected to the first slider 1283.

[0095] Similarly, the floor brush 120 also has a second connector (not shown in the figure), and the first base 128 has a second end (not shown in the figure), which is opposite to the first end 12811; the second end is provided with an open third semi-circular groove, and the second connector is provided with an open fourth semi-circular groove. When the second connector is connected to the first base 128, the third semi-circular groove and the fourth semi-circular groove are joined to form a second mounting groove; a second slider (not shown in the figure) is provided in the second mounting groove, and the second slider is connected to the second connecting rod 1231.

[0096] The first drive member 1285 and the second drive member are connected to the control unit. When the cleaning member 123 moves away from the suction port 122, the control unit drives the output ends of the first drive member 1285 and the second drive member to run in the first rotation direction. After the first drive member 1285 runs, it drives the first worm gear 1284 and the first transmission rod 1282 to run. After the first transmission rod 1282 runs, it drives the first slider 1283 to move away from the suction port 122. After the second drive member runs, it drives the second worm gear and the second transmission rod to run. After the second transmission rod runs, it drives the second slider to move away from the suction port 122. When both the first slider 1283 and the second slider move away from the suction port 122, they drive the cleaning member 123 to move away from the suction port 122.

[0097] When the cleaning component 123 moves towards the suction port 122, the control unit drives the output ends of the first driving component 1285 and the second driving component to operate in the second rotation direction. After the first driving component 1285 operates, it drives the first worm gear 1284 and the first transmission rod 1282 to operate.

After the second driving component operates, it drives the second worm gear and the second transmission rod to operate. After the second transmission rod operates, it drives the second slider to move towards the suction port 122. When both the first slider 1283 and the second slider move towards the suction port 122, the cleaning component 123 moves towards the suction port 122.
