Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and specifically to a cleaning device, a side brush assembly, and a control method for the cleaning device. Background Technology

[0002] With the development of social productivity, people's living standards have also improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment. However, the cleaning effectiveness of cleaning equipment at the edges (such as the junction of walls, furniture sides, and the floor) has always been a challenge for the industry. In particular, traditional rollers, brushes, or mop pads are ineffective at cleaning the corners formed by two walls, resulting in cleaning dead zones.

[0003] In existing technologies, side brushes can be installed on cleaning equipment. The bristles of these side brushes can reach into corner areas and sweep dust into the suction port during rotation, thus achieving a sweeping effect. However, this cleaning effect is relatively poor. When there is stubborn dirt or water stains on the floor, the bristles cannot effectively clean them. Therefore, improving the cleaning effect in corner areas is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0047] After the second cleaning unit finishes cleaning, the side brush assembly is controlled to rotate in the first direction opposite to the second direction, so that the working surface of the first preset area can be cleaned again by the first cleaning unit.

[0048] One beneficial effect of this disclosure is that the first cleaning unit is constructed to extend downwards from the base to the working surface, thereby overcoming the limitations of the machine body structure. The first cleaning unit can extend to the edge area on the outside of the machine body, thereby covering cleaning blind spots and achieving comprehensive cleaning. Specifically, when the cleaning equipment travels to a corner, the first cleaning unit can extend into the corner area, thereby cleaning the floor in the corner area.

[0049] Furthermore, the first cleaning unit not only rotates with the base relative to the main body but also rotates around its own axis, thus creating a dual cleaning motion and generating a stronger active cleaning force. By rotating with the base, the first cleaning unit expands the cleaning range of the edge area; through its own rotation, it repeatedly scrapes and pushes dust and fine particles in the edge area, improving cleaning effectiveness and reducing dirt residue on the work surface. In addition, water can be applied to the first cleaning unit for cleaning; it can perform a mopping function during its rotation, thus cleaning stubborn dirt and water stains, and improving the cleaning effect in corner areas.

[0065] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0066] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0067] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0068] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0069] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0070] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0071] This disclosure provides a cleaning device and a side brush assembly. The cleaning device includes the side brush assembly. The specific structure and working principle of the cleaning device provided by this disclosure will be described in detail below with reference to the accompanying drawings. The specific structure and working principle of the side brush assembly provided by this disclosure will also be introduced at the same time.

[0072] This embodiment provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, handheld vacuum cleaner, handheld floor scrubber, handheld fabric cleaner, or other handheld cleaning devices well known to those skilled in the art. It can also be a robotic vacuum cleaner, robotic mop, or a combined sweeping and mopping robot, used to clean work surfaces such as floors, sofas, and carpets.

[0073] This embodiment uses a robot that combines sweeping and mopping as an example of cleaning equipment. (Refer to...) Figure 3 The cleaning equipment includes a main body 1 and a side brush assembly 2 that rotates relative to the main body 1. The main body 1 is the main frame of the equipment, which is used to support the side brush assembly 2, the main cleaning unit (such as a roller brush 3, a suction port 5, etc.), the wheels, and other core components. The edge of the main body 1 is reserved for the installation space of the side brush assembly 2.

[0074] In one embodiment of this disclosure, a main cleaning unit is provided on the body 1. This main cleaning unit can be a roller brush 3, which is rotatably connected to the body 1, thereby enabling it to clean the work surface during rotation. The outer surface of the roller brush 3 can be provided with cleaning cotton, brush bristles, a cloth, or other cleaning components, allowing the roller brush 3 to wet-mop the work surface during rotation. Taking the direction of travel of the cleaning equipment as forward, the roller brush 3 can be rotatably connected to one side of the body 1 in the front-rear direction, and a traveling wheel can be provided on the other side. The traveling wheel can rotate under its own driving force, allowing the cleaning equipment to move freely across the work surface, thereby cleaning all work surfaces in the house.

[0075] The projection of the main body 1 on the working surface can completely cover the projection of the main cleaning unit on the working surface. In order for the roller brush 3 to be able to rotate normally, its length usually cannot extend beyond the main body 1. When the cleaning equipment travels to the edge of the wall, furniture, etc. for edge cleaning, the sides of the roller brush 3 will be a certain distance away from the edge of the wall, furniture, etc., resulting in cleaning dead corners.

[0076] To address the issues of unevenness between the roller brush 3 and the sides of the body 1, resulting in the inability to achieve zero-edge cleaning and poor cleaning performance, refer to... Figure 1 In existing technology, the roller brush 3 can be configured to float laterally relative to the body 1. Specifically, the roller brush 3 can be floatingly connected to the motion mechanism via an elastic component, allowing the roller brush 3 to remain in an outwardly extended position relative to the body 1 during edge cleaning, thereby conforming to the wall edge and increasing the cleaning coverage area; when the side of the roller brush 3 collides with an obstacle such as a wall, the roller brush 3 can adaptively retract inward, and after the external force is removed, the roller brush 3 can return to its original position under the action of elasticity. However, as Figure 1 As shown, even when the roller brush 3 remains extended, it is unable to clean the inside corner area 4, such as the corner of a wall.

[0077] In another existing technical solution, reference Figure 2 A side brush can be installed at the front side of the main body 1. The bristles of the side brush can reach into the corner area 4 for cleaning. When the side brush rotates, the bristles can sweep the dust on the ground towards the suction port 5 in the center of the main body 1, where it can be sucked away. The bristles are made of flexible material, and the bristles extending to the outside of the main body 1 can naturally deform when they come into contact with obstacles such as walls, thus preventing the cleaning device from getting stuck. However, the bristles can only sweep the corner area 4, not mop it. Understandably, the corner area 4 is prone to accumulating dirt and grime. When faced with stubborn dirt and water stains on the ground, the side brush bristles cannot clean effectively, and may even sweep liquid dirt towards the suction port 5, causing the dust collection box to become damp. Dirty water may drip from the suction port 5, contaminating the ground.

[0078] To improve the cleaning effect on the corner area 4, the body 1 of this disclosure is provided with a side brush assembly 2. The side brush assembly 2 can be installed on the left and / or right side of the body 1, and its projection edge on the working surface exceeds the projection of the body 1 on the working surface. Thus, the side brush assembly 2 can clean the working surface located from the side of the roller brush 3 to the outside of the body 1, expanding the cleaning area and making up for the cleaning blind spots of the traditional roller brush 3. This allows the cleaning equipment of this disclosure to reduce the distance between the cleaning unit and the wall or other obstacles when cleaning along the wall or other obstacles, and to clean blind spots (such as the corner area 4) that the roller brush 3 cannot reach, reducing the omission of dirt in blind spots and improving the user experience.

[0079] refer to Figures 3 to 5 The side brush assembly 2 is configured to rotate relative to the body 1. Specifically, the side brush assembly 2 includes a base 20 and a first cleaning unit 21. The base 20 is rotatably connected to the body 1. The base 20 is the mounting base of the side brush assembly 2. One end of it is rotatably connected to the body 1 through a transmission structure, and the other end provides a mounting point for the first cleaning unit 21.

[0080] In one embodiment of this disclosure, reference is made to Figure 3 A rotating base 12 is provided on the body 1 at the position corresponding to the side brush assembly 2. A drive shaft (not shown in the figure) is provided on the rotating base 12. A motor for driving the drive shaft to rotate can be provided inside the body 1, thereby enabling the drive shaft to rotate relative to the body 1. (Reference) Figure 4 The base 20 is provided with a mounting flange 201, and a transmission hole 202 is formed on the mounting flange 201. The transmission hole 202 is fitted onto the transmission shaft. The transmission hole 202 is constructed to be non-circular, and the shape of the transmission shaft is adapted to the transmission hole 202, so that the transmission shaft always maintains a fit with the inner wall of the transmission hole 202 when rotating, thereby driving the base 20 to rotate together through the mounting flange 201.

[0081] The first cleaning unit 21 is configured to extend downwards from the base 20 to the working surface, and cleans the working surface as the base 20 rotates. The first cleaning unit 21 is a cleaning component that directly acts on the working surface; one end is connected to the base 20, and the other end extends downwards towards the working surface. The specific tilt angle of the first cleaning unit 21 can be set according to actual edge-contact requirements, thereby ensuring that it can extend to areas outside the machine body 1. The first cleaning unit 21 of this disclosure extends downwards from the base 20 to the working surface, thus overcoming the limitations of the machine body 1 structure. The first cleaning unit 21 can extend to the edge-contact area outside the machine body 1, thereby covering cleaning blind spots and achieving comprehensive cleaning. Specifically, when the cleaning equipment travels to a corner, the first cleaning unit 21 can extend into the corner area 4, thereby cleaning the floor of the corner area 4.

[0082] Furthermore, the first cleaning unit 21 can also rotate about its own axis. For example... Figure 6 As shown, the first cleaning unit 21 includes a rotating shaft 211, which is rotatably connected to the base 20, thereby enabling the first cleaning unit 21 to rotate around its own axis. The first cleaning unit 21 of this disclosure not only rotates with the base 20 relative to the body 1, but also rotates around its own axis, thus forming a dual cleaning motion of "revolution + rotation," thereby generating a stronger active cleaning force. By rotating with the base 20, the first cleaning unit 21 expands the cleaning range of the edge area; by rotating, the first cleaning unit 21 can repeatedly scrape and push dust and fine particles in the edge area, improving the cleaning effect and reducing dirt residue on the working surface. Furthermore, water can be applied to the first cleaning unit 21 for cleaning; the first cleaning unit 21 can perform a mopping function during its rotation, thereby cleaning stubborn dirt and water stains, improving the cleaning effect of the corner area 4.

[0083] In one embodiment of this disclosure, a drive unit is provided on the base 20, and the drive unit is configured to drive the first cleaning unit 21 to rotate relative to the base 20. Specifically, the drive unit may be a micro motor disposed on the base 20, and the power output end of the drive unit may be connected to the rotating shaft 211 of the first cleaning unit 21 through a transmission structure, thereby achieving stable power transmission. At the same time, the drive unit may be controlled by the control unit of the cleaning equipment. The control unit may adjust the opening and closing and the rotation speed of the drive unit according to the current cleaning mode (such as edge cleaning mode, non-edge cleaning mode, etc.). For example, the rotation speed may be increased during edge cleaning to enhance the scraping force.

[0084] This embodiment achieves active rotation of the first cleaning unit 21 relative to the base 20 by setting a drive unit, making the rotation of the first cleaning unit 21 controllable and adjustable, thereby ensuring the cleaning effect. In addition, for different cleaning modes, working surface materials, types of dirt, and other specific scenarios, this embodiment can adaptively adjust the rotation speed of the first cleaning unit 21 by controlling the drive unit, thereby enhancing the cleaning adaptability.

[0085] In one embodiment of this disclosure, as the base 20 drives the first cleaning unit 21 to rotate, the first cleaning unit 21 rotates around its own axis due to the frictional force of the working surface. This embodiment relies on the frictional force of the working surface to achieve the rotation of the first cleaning unit 21, thus eliminating the need for a drive unit and a matching transmission structure, reducing drive costs; it also reduces the number of parts in the side brush assembly 2, reducing the space occupied by the base 20.

[0086] During operation, when the base 20 drives the first cleaning unit 21 to rotate around the machine body 1, the first cleaning unit 21 comes into contact with the working surface, generating friction. The direction of this friction is opposite to the tangential direction of the first cleaning unit 21's revolution around the base 20, thus creating torque on the first cleaning unit 21, which in turn drives it to rotate around its own axis. The faster the revolution speed, the greater the friction, and the rotation speed increases synchronously. This achieves speed linkage adjustment. When the base 20 increases its speed due to edge contact requirements, the rotation speed of the first cleaning unit 21 increases synchronously, thereby improving the cleaning effect.

[0087] In one embodiment of this disclosure, reference is made to Figure 4 and Figure 5 The base 20 is provided with a connecting portion 23, on which the first cleaning unit 21 is rotatably connected and configured to extend from the connecting portion 23 toward the working surface. The first cleaning unit 21 is indirectly connected to the base 20 via the connecting portion 23, and is rotatably connected to the connecting portion 23, thereby allowing it to rotate relative to the base 20 about its own axis under external force. One end of the connecting portion 23 is connected to the base 20, and the other end is connected to the rotating shaft 211 of the first cleaning unit 21, thus achieving a rotatable connection. The connecting portion 23 can extend obliquely from the base 20 toward the working surface, thereby ensuring that the first cleaning unit 21 at its other end can extend to an area outside the machine body 1.

[0088] In one specific embodiment of this disclosure, the connecting portion 23 is made of a flexible material and is configured to deform under external force. Optionally, the connecting portion 23 may be made of flexible materials such as silicone or rubber. The flexible material must meet the dual requirements of elastic recovery and support strength. Such materials can deform under force and quickly return to their original position after the force is released, avoiding permanent deformation. In this embodiment, the connecting portion 23 may be a columnar rubber strip.

[0089] When the first cleaning unit 21 encounters an obstacle during its rotation with the base 20, the connecting part 23 is compressed and bent, thereby buffering the impact and causing the first cleaning unit 21 to avoid the obstacle, preventing hard collisions and improving safety. Furthermore, when there are protrusions or depressions on the working surface, the connecting part 23 can adapt to the working surface, ensuring that the first cleaning unit 21 always fits the working surface, preventing it from being suspended and guaranteeing cleaning effectiveness.

[0090] In one embodiment of this disclosure, reference is made to Figure 3 The machine body 1 is provided with a spray hole 11. Liquid is sprayed through the spray hole 11 at least onto the working surface below the first cleaning unit 21, and / or onto the first cleaning unit 21. The spray hole 11 can be opened on the machine body 1 near the side brush assembly 2. In this embodiment, the side brush assembly 2 is located on the side of the machine body 1, so the spray hole 11 can be opened on that side. The spray hole 11 is connected to the clean water tank of the cleaning equipment through the internal pipeline of the machine body 1, thereby forming a liquid delivery channel. The cleaning medium stored in the clean water tank can be delivered to the spray hole 11 and sprayed outward through the spray hole 11.

[0091] The spray nozzle 11 can spray cleaning medium onto the working surface corresponding to the cleaning area of ​​the first cleaning unit 21. Specifically, the spray position can be aimed at the working surface below the first cleaning unit 21, thereby pre-wetting the dirt in that area, reducing the adhesion between the dirt and the working surface, and facilitating cleaning by the first cleaning unit 21. The spray nozzle 11 can also spray cleaning medium onto the first cleaning unit 21, for example, by aiming it at the cleaning surface of the first cleaning unit 21, keeping the first cleaning unit 21 moist, enhancing its ability to adsorb dust (preventing dust from being stirred up), and at the same time, the moist cleaning surface can dissolve dirt, thereby improving the cleaning effect of the first cleaning unit 21.

[0092] In one embodiment of this disclosure, a flow pipe is provided inside the first cleaning unit 21, and a liquid outlet is formed on the surface of the first cleaning unit 21 in the flow pipe; the liquid in the flow pipe is configured to flow out to the first cleaning unit 21 through the liquid outlet. Specifically, one end of the flow pipe in the first cleaning unit 21 is used to form a liquid outlet, and the other end can be connected to the internal pipe of the body 1 through the connecting part 23 and the liquid channel built into the base 20, and then connected to the clean water tank of the cleaning equipment, thereby forming a liquid transport passage. The cleaning medium stored in the clean water tank can be transported to the liquid outlet and flow directly to the surface of the first cleaning unit 21 through the liquid outlet.

[0093] This embodiment, by setting a flow channel in the first cleaning unit 21, allows the cleaning medium to flow directly inside the first cleaning unit 21. The cleaning medium can flow out evenly from the surface of the first cleaning unit 21, thereby achieving precise liquid supply and avoiding the loss problem caused by the uncontrollable landing point of the cleaning medium in the external spray scheme. In addition, when the cleaning medium flows out of the liquid outlet, it can wash away residual dirt on the surface of the first cleaning unit 21 in real time, reducing the accumulation of dirt on the first cleaning unit 21. The side brush assembly 2 can achieve self-cleaning simultaneously during the cleaning process, thereby reducing the user's maintenance frequency and extending the service life of the first cleaning unit 21.

[0094] In one embodiment of this disclosure, reference is made to Figure 6 The first cleaning unit 21 includes a roller 212, on the surface of which cleaning bristles are provided. The roller 212 can be a cylindrical structure sleeved on the outside of the rotating shaft 211. The roller 212 can rotate around the axis of the rotating shaft 211 as it rotates relative to the machine body 1 with the base 20, thereby generating a stronger active cleaning force. The outer surface of the roller 212 can be flocked with cleaning bristles, allowing the roller 212 to wet-mop the work surface during rotation, thus reaching into the corner area 4 for mopping and improving the cleaning effect of the corner area 4. Compared to traditional bristle-type side brushes (with large gaps between individual bristles, easily missing fine dust), this disclosure uses a roller 212 as the first cleaning unit 21, and the cleaning bristles on the surface of the roller 212 cover a large area, thereby effectively reducing dust omissions. Meanwhile, the cleaning bristles will not scratch sensitive surfaces such as wooden floors and marble when they come into contact with the work surface, and the soft contact reduces friction noise during rotation, avoiding the harsh friction noise of traditional hard brushes, thus improving the user experience in home settings.

[0095] In one embodiment of this disclosure, at least two first cleaning units 21 are provided, and the at least two first cleaning units 21 are configured to be distributed in the circumferential direction of the base 20. By providing at least two first cleaning units 21, the cleaning effect of the side brush assembly 2 is further improved. The specific number of first cleaning units 21 can be set according to the size of the base 20 and the actual edge-fitting requirements. Each first cleaning unit 21 is rotatably connected to the base 20 or the connecting part 23 through an independent rotating shaft 211, ensuring that each can rotate independently around its own axis, and all first cleaning units 21 can rotate synchronously around the body 1 with the base 20. The tilt angle, extension length, and other parameters of each first cleaning unit 21 can be set to be consistent, or can be finely adjusted according to actual needs, thereby ensuring the best edge-fitting cleaning effect.

[0096] This disclosure enhances the edge cleaning intensity by setting at least two first cleaning units 21. Multiple first cleaning units 21 act simultaneously on the edge area (such as the inner corner area 4), forming a superimposed cleaning force through a dual motion of "revolution + rotation," thereby improving the dirt removal rate at the edge location. Furthermore, in schemes with a single first cleaning unit 21, the base 20 is prone to wobbling or even eccentric rotation due to excessive force on one side; however, this embodiment balances the force on the base 20 by setting at least two circumferentially distributed first cleaning units 21, improving the working stability of the side brush assembly 2. Simultaneously, if one of the first cleaning units 21 temporarily fails (e.g., due to rotational jamming), the other first cleaning units 21 can still maintain the edge cleaning function, thereby enhancing the fault tolerance of the side brush assembly 2.

[0097] In one embodiment of this disclosure, such as Figure 4 As shown, the cleaning equipment also includes a second cleaning unit 22 rotatably connected to the base 20. The second cleaning unit 22 extends obliquely from the base 20 to the working surface and is configured to clean the working surface as it rotates with the base 20. Specifically, the second cleaning unit 22 differs from the first cleaning unit 21. For example, the first cleaning unit 21 can be a roller 212 with cleaning bristles, mainly used for wet mopping the working surface; while the second cleaning unit 22 can be a bristle bundle, mainly used for sweeping away debris and crumbs on the working surface, or the second cleaning unit 22 can be a scraper, mainly used for scraping away liquids on the working surface. The second cleaning unit 22 and the first cleaning unit 21 can complement each other, achieving multi-functional collaborative cleaning and improving the overall functionality of the side brush assembly 2.

[0098] The first cleaning unit 21 and the second cleaning unit 22 are arranged at intervals in the circumferential direction of the base 20. Compared with the scheme of setting a single first cleaning unit 21, this embodiment balances the force on the base 20 and improves the working stability of the side brush assembly 2. During operation, the second cleaning unit 22 and the first cleaning unit 21 rotate synchronously around the body 1 with the base 20. The second cleaning unit 22 can be configured to be unable to rotate around its own axis, and it can clean the working surface while rotating with the base 20.

[0099] In one specific embodiment of this disclosure, the second cleaning unit 22 is a brush. The material of the brush can be selected from nylon, PP fiber, etc., and the brush bristles are arranged in a dense manner to form bristle bundles. The second cleaning unit 22 may include multiple bristle bundles. The brush bristles can extend obliquely from the base 20 to the working surface, thereby ensuring that at least some of the brush bristles can extend to areas outside the body 1, so that the second cleaning unit 22 can achieve edge cleaning.

[0100] Furthermore, the hardness of the first cleaning unit 21 can be less than the hardness of the brush bristles. This disclosure achieves a dual cleaning effect of "coarse cleaning + fine cleaning" by setting a first cleaning unit 21 with lower hardness and a second cleaning unit 22 with higher hardness. Specifically, the second cleaning unit 22 with higher hardness (such as brush bristles) can effectively loosen stubborn dirt (such as residue and debris stuck to the ground, hardened dust in the ground gaps) in the edge area by scraping as it rotates with the base 20; the first cleaning unit 21 with lower hardness (such as a roller 212 with cleaning bristles) can rotate on its own while rotating with the base 20, thereby rolling on the working surface and thoroughly cleaning the loosened fine dirt and dust, avoiding cleaning residue caused by the high-hardness second cleaning unit 22 not being able to completely adhere to the working surface.

[0101] In one embodiment of this disclosure, the first cleaning unit 21 is constructed using a flexible material and is configured to deform relative to the working surface. Specifically, in embodiments where the first cleaning unit 21 includes a roller 212, the body of the roller 212 can be made of a flexible material, and the cleaning fibers implanted or bonded to its surface are also flexible. When subjected to external force, both the roller 212 and the cleaning fibers can deform. Optionally, the body of the roller 212 can be made of flexible materials such as silicone or rubber. The flexible material needs to meet the dual requirements of elastic recovery and support strength. Such materials can deform under force and quickly return to their original position after the force is released, avoiding permanent deformation.

[0102] During actual edge-applying operations, when the first cleaning unit 21 comes into contact with obstacles such as walls, baseboards, and furniture, the flexible first cleaning unit 21 is compressed and bent, thereby providing cushioning and preventing hard collisions that could cause the cleaning equipment to get stuck or furniture surfaces to be scratched and damaged. This improves the mobility and safety of the cleaning equipment. Furthermore, when there are protrusions or depressions on the work surface, the first cleaning unit 21 can adapt its deformation relative to the work surface, ensuring that it always adheres to the work surface, preventing it from being suspended and guaranteeing cleaning effectiveness.

[0103] Furthermore, existing non-flexible side brushes cannot adapt to irregular edge areas. Even if their cleaning range extends beyond the body 1, their rigid structure still makes it difficult to adapt and reach into complex cleaning dead corners, thus failing to achieve true zero-edge cleaning. In contrast, this disclosure, by setting a flexible first cleaning unit 21, can adaptively deform with the surrounding environment, thereby reaching into cleaning dead corners and extending the cleaning coverage to areas that traditional rigid cleaning units cannot reach, truly achieving a zero-edge cleaning effect.

[0104] In one embodiment of this disclosure, the first cleaning unit 21 and the second cleaning unit 22 are configured to move between a first position in contact with the work surface and a second position away from the work surface. When in the first position, the first cleaning unit 21 and / or the second cleaning unit 22 can contact the work surface and clean it. Specifically, in an embodiment where the first cleaning unit 21 includes a roller 212, the first cleaning unit 21 performs mopping when in the first position; in an embodiment where the second cleaning unit 22 includes bristles, the second cleaning unit 22 can perform sweeping (e.g., sweeping dust towards the suction port 5) when in the first position. In contrast, the second position refers to a non-working position where the entire cleaning unit maintains a certain gap with the work surface.

[0105] Furthermore, while the side brush assembly 2 in the previous embodiment can sweep and mop the corner area 4, the sweeping bristles and the mopping unit contact the ground simultaneously, causing the mopping unit to be covered with dust swept up by the bristles, or the bristles to become wet and sticky with hair. In this embodiment, the first cleaning unit 21 and the second cleaning unit 22 are used for wet mopping and sweeping, respectively, and both are connected to the base 20. When the base 20 rotates, the cleaning range of the two cleaning units is basically the same, which can easily cause them to interfere with each other.

[0106] To address the aforementioned issues, when the first cleaning unit 21 is in the first position, the second cleaning unit 22 is in the second position; conversely, when the first cleaning unit 21 is in the second position, the second cleaning unit 22 is in the first position. This avoids the first cleaning unit 21 and the second cleaning unit 22 simultaneously contacting the work surface, allowing them to work separately and preventing interference between the sweeping and mopping functions. Specifically, when the first cleaning unit 21 is in the first position mopping, the second cleaning unit 22 is raised to avoid getting wet; conversely, when the second cleaning unit 22 is in the first position sweeping, the first cleaning unit 21 is raised to avoid picking up dust. This prevents interference caused by the simultaneous operation of the first cleaning unit 21 and the second cleaning unit 22, improving both cleaning effectiveness and efficiency.

[0107] In addition, as a component that is in long-term frictional contact with the working surface, the cleaning unit is prone to wear after a period of use. In this embodiment, the first cleaning unit 21 and the second cleaning unit 22 only move to the first position in contact with the working surface when they need to work, and can be lifted when the other is working, thereby reducing the friction time with the working surface and extending the service life of the side brush assembly 2.

[0108] Furthermore, the first cleaning unit 21 and the second cleaning unit 22 can be rotatably connected to the base 20, and the two can be flipped relative to the base 20 respectively, thereby realizing the position switching between the first position and the second position. Figure 7The diagram shows the situation where the first cleaning unit 21 is in the first position and the second cleaning unit 22 is in the second position. Figure 8 The diagram shows the situation where the first cleaning unit 21 is in the second position and the second cleaning unit 22 is in the first position. Optionally, the first cleaning unit 21 and / or the second cleaning unit 22 can be rotated by an angle of 180° when switching positions, thereby ensuring that the cleaning unit in the second position does not come into contact with the working surface at all.

[0109] In one embodiment of this disclosure, the cleaning device further includes a transmission unit disposed on the base 20. The transmission unit is configured to drive the first cleaning unit 21 to a first position and simultaneously drive the second cleaning unit 22 to a second position when the base 20 rotates in a first direction, and is also configured to drive the first cleaning unit 21 to the second position and simultaneously drive the second cleaning unit 22 to the first position when the base 20 rotates in a second direction. Specifically, the first and second directions are opposite. As mentioned above, the base 20 can rotate under the drive of a motor within the body 1. The motor can rotate forward and reverse, thereby driving the base 20 and the transmission unit to rotate in the first and second directions, respectively. By providing a transmission unit, this disclosure allows the position switching of the cleaning units to be achieved using the rotational power of the base 20 itself, without the need for additional driving force, thus reducing the driving cost of the side brush assembly 2.

[0110] Specifically, refer to Figure 9 In one specific embodiment, the transmission unit may include a reversing shaft 7 at least partially installed in the base 20. One end of the reversing shaft 7 extending into the base 20 is configured to drive the first cleaning unit 21 and the second cleaning unit 22 respectively. Multiple rotating grooves 24 are provided on the side of the base 20, and the first cleaning unit 21 and the second cleaning unit 22 are rotatably connected to the base 20 through these rotating grooves 24. When the base 20 rotates under the drive of a motor within the body 1, the inner wall of the rotating groove 24 applies rotational force to the first cleaning unit 21 and the second cleaning unit 22, and the first cleaning unit 21 and the second cleaning unit 22 can apply corresponding rotational force to the reversing shaft 7.

[0111] like Figure 9 As shown, a gear disk 71 can be provided at the bottom of the reversing shaft 7. A meshing gear 61 is provided on one end of the first cleaning unit 21 and the second cleaning unit 22 located inside the base 20. The meshing gear 61 meshes with the gear disk 71, thereby realizing the transmission connection between the cleaning unit and the reversing shaft 7. When the base 20 drives the first cleaning unit 21 and the second cleaning unit 22 to rotate, the meshing gear 61 has a rotational tendency under the interaction with the gear disk 71, thereby being able to flip relative to the base 20 and realize position switching.

[0112] like Figure 10 As shown, in another embodiment of this disclosure, a flange 72 may be provided at the bottom of the reversing shaft 7. A first abutment portion 621 and a second abutment portion 622 are provided on one end of the first cleaning unit 21 and the second cleaning unit 22 located within the base 20. The first abutment portion 621 and the second abutment portion 622 are configured to have a predetermined included angle, and the flange 72 is configured to restrict movement between the first abutment portion 621 and the second abutment portion 622. Preferably, the extending directions of the first abutment portion 621 and the second abutment portion 622 may be perpendicular to each other, and the first abutment portion 621 and the second abutment portion 622 are integrally formed rocker arms. An arc-shaped groove 623 is formed at the connection position of the first abutment portion 621 and the second abutment portion 622, and the flange 72 is configured to be restricted at the position of the arc-shaped groove 623. When the base 20 drives the first cleaning unit 21 and the second cleaning unit 22 to rotate, the flange 72 can abut against the first abutting part 621 or the second abutting part 622, thereby applying a force, which causes the first cleaning unit 21 and the second cleaning unit 22 to flip relative to the base 20, thus achieving a position switch.

[0113] In one specific embodiment of this disclosure, the transmission unit is at least partially located inside the base 20, and it can simultaneously cooperate with the first cleaning unit 21 and the second cleaning unit 22 to simultaneously drive them to switch positions. The transmission unit may include a damper and a switching element, wherein the switching element can drive the cleaning unit to switch positions during movement, and it may be the reversing shaft 7 mentioned above; the damper can apply rotational resistance to the switching element.

[0114] When the base 20 begins to rotate in the first direction, the first cleaning unit 21 and the second cleaning unit 22 tend to rotate in the first direction along with the base 20, and the switching member receives the transmission force from the cleaning unit. Since the rotational resistance between the switching member and the damper is greater than the transmission force applied by the cleaning unit, the switching member will not immediately rotate in the first direction, but will instead apply a force in the opposite direction to the first cleaning unit 21 and the second cleaning unit 22. This causes the first cleaning unit 21 and the second cleaning unit 22 to rotate relative to the base 20, thereby moving the first cleaning unit 21 to the first position and the second cleaning unit 22 to the second position. The cleaning unit that has completed the position switching can continue to transmit rotational force to the switching member until it overcomes the resistance from the damper, thereby causing the switching member to rotate together in the first direction. The first cleaning unit 21 can achieve stable cleaning during rotation.

[0115] Similarly, when the base 20 rotates in the second direction, the rotational resistance of the damper causes the switching element to exert opposing forces on the first cleaning unit 21 and the second cleaning unit 22. This causes the first cleaning unit 21 and the second cleaning unit 22 to rotate relative to the base 20, thereby moving the first cleaning unit 21 to the second position and the second cleaning unit 22 to the first position. The cleaning unit that has completed the position switching can drive the switching element to rotate together in the second direction, and the second cleaning unit 22 can achieve stable cleaning during the rotation.

[0116] In one embodiment of this disclosure, when the cleaning device cleans a first preset area, the first cleaning unit 21 is located in a first position and is configured to clean the working surface as it rotates with the base 20; when the cleaning device cleans a second preset area, the second cleaning unit 22 is located in the first position and is configured to clean the working surface as it rotates with the base 20. Specifically, the first preset area may include edge areas and / or corner areas on the working surface; the second preset area may include non-edge areas on the working surface.

[0117] The first preset area (edge / corner position) is a blind spot for the main cleaning unit (roller brush 3). In existing cleaning devices with side brushes, the cleaning effect is poor because the brush bristles, similar to those of the second cleaning unit 22, are used to sweep dust along the edges. When cleaning the first preset area, that is, when the cleaning device sweeps along the edges, the cleaning device of this disclosure can control the first cleaning unit 21 to be in a first position. The first cleaning unit 21 can reach into the edge and corner areas to mop, thereby improving the cleaning effect.

[0118] When cleaning non-edge areas, the main cleaning unit (roller brush 3) can perform wet mopping cleaning on its own, so the first cleaning unit 21 does not need to work and can remain in the second position to avoid unnecessary wear and tear. At this time, the second cleaning unit 22 is in the first position. The bristles of the second cleaning unit 22 can sweep dust towards the roller brush 3, the suction port 5, etc., thereby working in conjunction with the main cleaning unit to improve cleaning efficiency.

[0119] This disclosure also provides a control method for a cleaning device, applicable to the cleaning device described above. The method includes: when the cleaning device is cleaning a first preset area, controlling the first cleaning unit 21 to move to a first position contacting the working surface; and when the cleaning device is cleaning a second preset area, controlling the first cleaning unit 21 to move to a second position away from the working surface. Specifically, taking the first preset area as an edge area and the second preset area as a non-edge area as an example, the cleaning device can determine the current area type through an infrared distance sensor, a visual sensor, or a map established by radar at the edge of the body 1.

[0120] If it is determined that the current location is in the first preset area, the base 20 is controlled to rotate in the first direction, thereby driving the first cleaning unit 21 to move to the first position through the transmission unit, so that the first cleaning unit 21 can reach into the corners, edges and other blind spots of cleaning, and achieve the effect of edge cleaning.

[0121] If it is determined that the current location is in the second preset area, the base 20 is controlled to rotate in the second direction, thereby driving the first cleaning unit 21 to move to the second position through the transmission unit, so that the first cleaning unit 21 can be lifted away from the working surface, avoiding wear caused by long-term contact with the working surface and extending the service life of the first cleaning unit 21.

[0122] Furthermore, in one embodiment of this disclosure, the control method further includes: when the cleaning device is cleaning the first preset area, controlling the second cleaning unit 22 to move to a second position away from the working surface; and when the cleaning device is cleaning the second preset area, controlling the second cleaning unit 22 to move to a first position in contact with the working surface. This avoids the first cleaning unit 21 and the second cleaning unit 22 from simultaneously contacting the working surface, allowing them to work separately and thus preventing interference between the sweeping and mopping functions. Specifically, when the first cleaning unit 21 is in the first position mopping, the second cleaning unit 22 is lifted, thus preventing it from getting wet; when the second cleaning unit 22 is in the first position sweeping, the first cleaning unit 21 is lifted, thus preventing it from getting dusty. This avoids interference caused by the simultaneous operation of the first cleaning unit 21 and the second cleaning unit 22, improving cleaning effect and efficiency.

[0123] This disclosure also provides a control method for a cleaning device, applicable to the aforementioned cleaning device. The method includes controlling the side brush assembly 2 to rotate in a second direction to clean the work surface via the second cleaning unit 22. Specifically, during normal cleaning operation, the side brush assembly 2 can be controlled to rotate in the second direction by default. At this time, the second cleaning unit 22 can remain in a first position in contact with the work surface and clean the work surface while rotating with the base 20. The bristles of the second cleaning unit 22 can sweep dust towards the roller brush 3, suction port 5, etc., thereby working in conjunction with the main cleaning unit to improve cleaning efficiency.

[0124] When the cleaning equipment detects a first preset area, it controls the side brush assembly 2 to rotate in the first direction, opposite to the second direction, so that the first cleaning unit 21 can clean the working surface. Specifically, the first preset area is an edge area or a corner area 4. The cleaning equipment can identify the type of area it is about to enter through infrared distance sensors, vision sensors, or radar maps built on the edge of the body 1. When the first preset area is detected, the side brush assembly 2 is controlled to reverse, that is, rotate in the first direction. The first cleaning unit 21 and the second cleaning unit 22 rotate relative to the base 20, so that the first cleaning unit 21 moves to the first position and the second cleaning unit 22 moves to the second position. As the base 20 continues to rotate in the first direction, the first cleaning unit 21 can remain in the first position in contact with the working surface and clean the working surface while following the rotation of the base 20.

[0125] In one embodiment of this disclosure, the control method further includes: during the cleaning of the work surface by the first cleaning unit 21, controlling the liquid to be sprayed through the spray nozzle 11 at least onto the work surface below the first cleaning unit 21, and / or onto the first cleaning unit 21. Specifically, the first cleaning unit 21 can perform wet mopping on the work surface of a first preset area, and the spray nozzle 11 can spray the cleaning medium onto the work surface corresponding to the cleaning area of ​​the first cleaning unit 21, thereby pre-wetting the dirt in that area, reducing the adhesion between the dirt and the work surface, and facilitating the wet mopping cleaning by the first cleaning unit 21. The spray nozzle 11 can also spray the cleaning medium onto the first cleaning unit 21, for example, by aiming it at the cleaning surface of the first cleaning unit 21, keeping the first cleaning unit 21 moist, enhancing its ability to adsorb dust (preventing dust from being stirred up), and at the same time, the moist cleaning surface can dissolve dirt, thereby improving the cleaning effect of the first cleaning unit 21.

[0126] In one embodiment of this disclosure, the control method further includes: when the cleaning device cleans the first preset area, controlling the side brush assembly 2 to rotate in a second direction so as to clean the working surface of the first preset area through the second cleaning unit 22; after the second cleaning unit 22 has finished cleaning, controlling the side brush assembly 2 to rotate in a first direction opposite to the second direction so as to clean the working surface of the first preset area again through the first cleaning unit 21.

[0127] Specifically, when the cleaning equipment detects the first preset area, it does not immediately control the side brush assembly 2 to reverse, but continues to rotate in the second direction. This allows the second cleaning unit 22 to clean the working surface of the first preset area, with the brush bristles pre-sweeping away any floating dust. After sweeping is complete (i.e., after the second cleaning unit 22 has finished cleaning), the side brush assembly 2 is then controlled to reverse, thereby switching the positions of the first cleaning unit 21 and the second cleaning unit 22. While continuing to rotate in the first direction, the first cleaning unit 21 remains in contact with the working surface and cleans the surface as it rotates with the base 20. This creates a sweep-then-mop sequence, improving the cleaning effect on the first preset area (such as the corner area 4) and preventing interference caused by the first cleaning unit 21 and the second cleaning unit 22 simultaneously contacting the ground.

[0128] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments.
