Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and specifically to a cleaning device. Background Technology

[0002] With the development of technology and the improvement of people's quality of life, cleaning equipment is being used more and more in people's lives.

[0003] Cleaning equipment consists of a main unit and a floor brush. When a user rotates the main unit relative to the floor brush during use, they need to manually return the main unit to its original position before rotation. This interrupts the cleaning process, reduces cleaning efficiency, and also degrades the user experience. Summary of the Invention

[0004] This application provides a cleaning device that improves the user experience.

[0005] This application provides a cleaning device, which includes a body and a floor brush assembly. The floor brush assembly includes a rotating structure and a floor brush. The rotating structure includes a first rotating member, a second rotating member, and a first elastic member. The second rotating member is adapted to connect to the body. The rotation center line of the second rotating member and the first rotating member is a first rotation center line. The second rotating member and the first rotating member rotate relative to each other to switch between a first position and a second position, such that the body rotates to the left or right position around the first rotation center line. When the second rotating member and the first rotating member switch between the first position and the second position, they pass through a third position. The first elastic member is disposed between the first rotating member and the second rotating member. The first elastic member is configured to provide a restoring force to the second rotating member in the first position to switch to the third position. The floor brush includes a housing and a wiping disc assembly. The housing is rotatably connected to the first rotating member. In the first position, when the first elastic member is in a compressed state, the first elastic member and the wiping disc assembly are located on the same side of the first rotation center line along a first direction; or, in the first position, when the first elastic member is in a stretched state, the first elastic member and the wiping disc assembly are located on opposite sides of the first rotation center line along a first direction.

[0006] In current technology, in order to enhance the cleaning ability of floor scrubbers, some manufacturers have begun to add cleaning components to the floor brushes of floor scrubbers. These cleaning components can be disc brushes, and the solution of using disc brushes for auxiliary cleaning differs from existing sweeping machines, which are generally disc-shaped automatic machines with concentrated components.

[0007] Therefore, the force of the entire component is relatively concentrated, and the external influence it receives during movement is small, making it less likely to lose control. At the same time, sweepers are generally equipped with two disc brushes that rotate relative to each other, thereby achieving mutual cancellation of forces.

[0008] Unlike floor scrubbers, floor scrubbers have a flexible, rotatable body mounted above the floor brush for the user to hold. As a result, their components are not concentrated, and they are subject to many external forces, making them highly susceptible to loss of control due to external influences.

[0009] Furthermore, current floor scrubbers are all equipped with a single disc brush structure. Therefore, in actual cleaning, the force of the disc brush can easily affect the operation of the entire floor scrubber.

[0010] This application further counteracts the swaying caused by the disc brush by setting an elastic element, which helps to avoid interrupting the cleaning process and thus improves the user experience. At the same time, although an elastic element is added, it does not completely restrict the rotation of the machine body and the floor brush, thus ensuring that the flexibility of rotation is maintained while preventing the floor brush from deflecting randomly.

[0011] According to the cleaning device of this application embodiment, by switching a first rotating component connected to the floor brush and a second rotating component connected to the main body around a first rotation center line between a first position and a second position, and by providing a first elastic component between the first and second rotating components, when the user rotates the second rotating component to the first position, the first elastic component stores elastic potential energy. When the user releases the operating force, the elastic potential energy stored in the first elastic component is converted into a restoring force that drives the second rotating component to switch to a third position between the first and second positions, allowing the second rotating component to automatically return to the third position. This eliminates the need for the user to manually adjust the position of the main body, thus avoiding interruptions to the cleaning process. Furthermore, the operation is simple, reducing the user's learning curve and improving the user experience. Simultaneously, the simple structure reduces the manufacturing cost of the rotating structure. In addition, the arrangement of the first elastic component is related to the position of the wiping disc assembly, which helps to balance or counteract the asymmetrical frictional torque generated during turning, making the return movement of the cleaning device to the third position smoother and more stable, thereby improving the stability and reliability of the cleaning device.

[0012] In one possible implementation of this application, in a first position, the first elastic member is in a compressed state, and the first elastic member and the wiping plate assembly are located on the same side of the first rotation centerline; the rotation structure further includes a second elastic member, which is disposed between the first rotating member and the second rotating member, and is located on opposite sides of the wiping plate assembly on the first rotation centerline; the second elastic member is configured to provide a restoring force to the second rotating member in the second position to switch to the third position, and the stiffness of the first elastic member is greater than the stiffness of the second elastic member.

[0013] In one possible implementation of this application, in a first position, the first elastic member is in a stretched state, and the first elastic member and the wiping disc assembly are located on opposite sides of the first rotation centerline along a first direction. The rotating structure further includes a second elastic member disposed between the first rotating member and the second rotating member, and located on the same side of the first rotation centerline as the wiping disc assembly; the second elastic member is configured to provide a restoring force to the second rotating member in the second position for switching to a third position, and the stiffness of the first elastic member is greater than the stiffness of the second elastic member.

[0017] In one possible implementation of this application, the first sliding member has a first mounting cavity, the first mounting cavity being open on one side facing the bottom wall of the first limiting groove, and a portion of the first elastic member is located in the first mounting cavity.

[0018] In one possible implementation of this application, a first mounting post is provided on the bottom wall of the first limiting groove, and one end of the first elastic member is sleeved on the first mounting post.

[0019] In one possible implementation of this application, the second rotating member includes a mounting portion and two rotating portions. The mounting portion is adapted to be connected to the body, and the two rotating portions protrude from the mounting portion. The two rotating portions are arranged opposite to each other in the extension direction of the first rotation center line. A portion of the first rotating member is located between the two rotating portions and is rotatably connected to the two rotating portions. Along the arrangement direction of the mounting portion and the first rotating member, the first elastic member is located between the mounting portion and the first rotating member.

[0020] In one possible implementation of this application, the end of the first rotating member facing the mounting portion is provided with a first protrusion. Along the arrangement direction of the mounting portion and the first rotating member, the first protrusion is directly opposite the first elastic member, and the first elastic member is located between the mounting portion and the first protrusion.

[0035] With the development of technology and the improvement of people's quality of life, cleaning equipment is being used more and more in people's lives.

[0036] Cleaning equipment consists of a main unit and a floor brush. When a user rotates the main unit relative to the floor brush during use, they need to manually return the main unit to its original position before rotation. This interrupts the cleaning process, reduces cleaning efficiency, and also degrades the user experience.

[0037] To address the aforementioned technical problems, this application provides a cleaning device.

[0038] The cleaning equipment according to the embodiments of this application will be described below.

[0039] Cleaning equipment can be floor scrubbers. For example, cleaning equipment can be fully automatic floor scrubbers, semi-automatic floor scrubbers, walk-behind floor scrubbers, ride-on floor scrubbers, etc.

[0040] The cleaning equipment is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a floor, wall, or the surface of an object to be cleaned with different degrees of roughness. The embodiments of this application do not specifically limit the type of surface to be cleaned.

[0041] Please see Figure 1 The cleaning equipment provided in this application includes a floor brush assembly 1000. The floor brush assembly 1000 includes a floor brush 100. During operation, the floor brush 100 moves across the surface to be cleaned, and the surface is cleaned by contacting and rubbing the floor brush 100 with the surface to be cleaned.

[0042] The floor brush 100 may be equipped with a wastewater tank. When the floor brush 100 is working on the surface to be cleaned, the dirt can be collected into the wastewater tank.

[0043] Therefore, by installing a wastewater tank on the floor brush 100, it is beneficial to reduce the loss of wastewater and garbage during transportation, improve cleaning efficiency, and ensure that dirt on the surface to be cleaned can be collected quickly and effectively. Furthermore, it allows users to directly empty the wastewater and garbage after cleaning, thereby reducing operation steps and cleaning time.

[0044] The floor brush 100 includes a housing 110 and a wiping disc assembly 120. The housing 110 is rotatably connected to the first rotating member 210. The wiping disc assembly 120 is mounted on the housing 110. The wiping disc assembly 120 has greater friction with the surface to be cleaned, and can be used to clean stubborn stains on the surface to be cleaned. Stubborn stains include, for example, stains with strong adhesion, thick stains, and heavy stains.

[0045] The wiping disc assembly 120 may include a rotary lifting mechanism 121 and a wiping disc 122. The rotary lifting mechanism 121 is mounted on the housing 110. The wiping disc 122 is connected to the rotary lifting mechanism 121. The rotary lifting mechanism 121 is used to drive the wiping disc 122 to rotate and lift. Specifically, when the wiping disc assembly 120 is not needed, it can be in a retracted position, with a gap between the wiping disc 122 and the surface to be cleaned. When the wiping disc assembly 120 needs to be used, the rotary lifting mechanism 121 drives the wiping disc 122 to rotate, and simultaneously drives the wiping disc 122 to descend, lowering it to the working position where it contacts the surface to be cleaned. The high-speed rotation of the wiping disc 122 cleans the stains on the surface.

[0046] The cleaning equipment may also include a body (not shown). The floor brush assembly 1000 may also include a rotating structure 200. The body is connected to the floor brush 100 via the rotating structure 200. The rotating structure 200 allows rotation between the body and the floor brush 100, thereby improving the mobility of the cleaning equipment.

[0047] The rotating structure 200 may contain pipes. The negative pressure source of the machine body can suck up dirt through the pipes.

[0048] The machine body can be equipped with components such as a clean water tank and a wastewater tank. The clean water tank is used to hold cleaning liquid. When the cleaning equipment is working, the cleaning liquid in the clean water tank is sprayed onto the floor brush 100 or the surface to be cleaned in front of the floor brush 100, working together with the floor brush 100 to clean the surface. Dirt on the surface to be cleaned, such as wastewater, particles, and hair, is sucked into the wastewater tank, thus completing the cleaning process.

[0049] Please see Figures 2-4 The rotating structure 200 provided in this application includes a first rotating member 210, a second rotating member 220, and a first elastic member 230. The first rotating member 210 is adapted to be connected to the housing 110. The second rotating member 220 is adapted to be connected to the fuselage.

[0050] The first rotating member 210 is rotatably connected to the housing 110, and the rotation center line of the first rotating member 210 and the floor brush 100 is the second rotation center line W2. The second rotation center line W2 extends along a first direction F1, which is perpendicular to the travel direction of the floor brush 100. Specifically, the first rotating member 210 can have a vertical position and a horizontal position. When the first rotating member 210 is in the vertical position, its extension direction is perpendicular to the travel direction of the floor brush 100. When the first rotating member 210 is in the horizontal position, its extension direction is parallel to the travel direction of the floor brush 100.

[0051] Therefore, the machine body can rotate relative to the brush 100 along the second rotation center line W2 via the first rotating component 210, allowing the machine body to switch between a vertical position and a horizontal position. When the machine body is in the vertical position, the user can clean the surface to be cleaned without bending over. When the machine body is in the horizontal position, it can be used to clean the underside of sofas, under beds, and other surfaces, thus making the cleaning equipment suitable for different cleaning scenarios and improving the user experience.

[0052] It should be noted that "vertical" includes absolute verticality and near verticality, where the acceptable deviation range for near verticality can be, for example, within 5°, 8° or 10°.

[0053] For example, the first rotating member 210 includes a main body 2101 and two rotating parts 2102. The two rotating parts 2102 are located at opposite ends of the main body 2101 along a first direction F1, so that the first rotating member 210 is formed into an inverted "T" shape. The two rotating parts 2102 pass through rotating holes on the floor brush 100, so that the first rotating member 210 can rotate relative to the floor brush 100 about a second rotation center line W2.

[0054] The second rotating member 220 rotates relative to the first rotating member 210 to switch between a first position S1 and a second position S2. The rotation center line between the second rotating member 220 and the first rotating member 210 is the first rotation center line W1. The first rotation center line W1 is perpendicular to the first direction F1.

[0055] Specifically, the floor brush 100 may have a first end and a second end facing away from each other along a first direction F1. When the second rotating member 220 switches to the first position S1, the second rotating member 220 rotates about the first rotation center line W1 towards the first end. When the second rotating member 220 switches to the second position S2, the second rotating member 220 rotates about the second rotation center line W2 towards the second end.

[0056] When the second rotating member 220 and the first rotating member 210 switch between the first position S1 and the second position S2, they pass through the third position S3, which is then located between the first position S1 and the second position S2. When the second rotating member 220 is in the third position S3, the fuselage can be in a vertical position. When the second rotating member 220 is in the first position S1, the fuselage rotates to the left around the first rotation center line W1, that is, the fuselage tilts to one side of the first direction F1. When the second rotating member 220 is in the second position S2, the fuselage rotates to the right around the first rotation center line W1, that is, the fuselage tilts to the other side of the first direction F1.

[0057] It should be noted that when a user uses the cleaning equipment, "left side" can refer to the user's left side and "right side" can refer to the user's right side; this application does not limit this.

[0058] The first elastic element 230 can be disposed between the first rotating element 210 and the second rotating element 220. Thus, when the first rotating element 210 and the second rotating element 220 rotate relative to each other, the first elastic element 230 can be compressed or stretched.

[0059] The first elastic element 230 is located on one side of the first rotation center line W1 along the first direction F1. Therefore, when the second rotating element 220 rotates around the first rotation center line W1, it can ensure that a force is generated on the first elastic element 230.

[0060] The first elastic element 230 is configured to provide a restoring force to the second rotating element 220 in the first position S1, switching it towards the third position S3. Specifically, when the first position S1 of the first elastic element 230 and the second rotating element 220 are on the same side of the first direction F1, the first elastic element 230 is in a compressed state. When the first position S1 of the first elastic element 230 and the second rotating element 220 are on different sides of the first direction F1, the first elastic element 230 is in a tensile state.

[0061] Therefore, when the second rotating member 220 rotates around the first rotation center line W1 to the first position S1, the first elastic member 230 can provide a restoring force to the second rotating member 220 to switch to the third position S3, so that the second rotating member 220 can return from the first position S1 to the third position S3.

[0062] For example, the first elastic member 230 can be located between the edge of the first rotating member 210 in the first direction F1 and the edge of the second rotating member 220 in the first direction F1. This allows for a better force to be applied to the first elastic member 230, and also facilitates the first elastic member 230 to generate a counterforce on the second rotating member 220, enabling the second rotating member 220 to return to the third position S3 more quickly.

[0063] For example, the first elastic element 230 may be a spring.

[0064] In addition, the first elastic member 230 can also be used to provide a restoring force to the second rotating member 220 in the second position S2 to switch to the third position S3.

[0065] In the first position S1, when the first elastic element 230 is in a compressed state, the first elastic element 230 and the wiping disc assembly 120 are located on the same side of the first rotation center line W1 along the first direction F1. Therefore, in the first position S1, when the first elastic element 230 in the compressed state needs to recover its deformation, it will drive the second rotating element 220 to switch to the third position S3.

[0066] Alternatively, in the first position S1, when the first elastic element 230 is in a stretched state, the first elastic element 230 and the wiping disc assembly 120 are located on opposite sides of the first rotation center line W1 along the first direction F1. Therefore, in the first position S1, if the first elastic element 230 in the stretched state needs to recover its deformation, it will drive the second rotating element 220 to switch to the third position S3.

[0067] According to the embodiments of the present application, the floor brush assembly 1000 switches between a first rotating member 210 connected to the floor brush 100 and a second rotating member 220 connected to the body around a first rotation center line W1, between a first position S1 and a second position S2. A first elastic member 230 is provided between the first rotating member 210 and the second rotating member 220. When the user rotates the second rotating member 220 to the first position S1, the first elastic member 230 stores elastic potential energy. When the user releases the operating force, the elastic potential energy stored in the first elastic member 230 is converted into a restoring force that drives the second rotating member 220 to switch to a third position S3 between the first position S1 and the second position S2. This allows the second rotating member 220 to automatically return to the third position S3, eliminating the need for the user to manually adjust the position of the body. This helps avoid interrupting the cleaning process, and the simple operation reduces the user's learning cost, thus improving the user experience. Simultaneously, the simple structure helps reduce the manufacturing cost of the rotating structure 200. Furthermore, the arrangement of the first elastic element 230 is related to the position of the wiping disc assembly 120, which helps to balance or counteract the asymmetrical frictional torque generated during turning, making the return of the cleaning equipment to the third position S3 smoother and more stable, thereby improving the stability and reliability of the cleaning equipment.

[0068] Please continue reading. Figures 1-4 In some embodiments, the rotating structure 200 further includes a second elastic member 240. The second elastic member 240 is disposed between the first rotating member 210 and the second rotating member 220, and is located on the other side of the first rotation center line along the first direction F1. The second elastic member 240 is configured to provide a restoring force to the second rotating member 220 in the second position S2 for switching to the third position S3, and the stiffness of the first elastic member 230 is greater than the stiffness of the second elastic member 240. This allows for better cooperation with the floor brush 100 having the wiping disc assembly 120, enabling the machine body to switch back to the third position S3 more stably. Furthermore, the structure is simple, thus helping to reduce the manufacturing cost of the cleaning equipment.

[0069] Please continue reading. Figures 2-4In some embodiments, one of the second rotating member 220 and the first rotating member 210 is provided with a first limiting groove 221. The first limiting groove 221 is open to the other side of the second rotating member 220 and the first rotating member 210. Specifically, the first limiting groove 221 may be provided on the second rotating member 220, and the first limiting groove 221 may be open to the side of the first rotating member 210. Alternatively, the first limiting groove 221 may be provided on the first rotating member 210, and the first limiting groove 221 may be open to the side of the second rotating member 220.

[0070] For example, the first limiting groove 221 can extend along a second direction. This second direction is perpendicular to both the first direction F1 and the travel direction of the floor brush 100. This facilitates the processing of the first limiting groove 221, thereby reducing the manufacturing cost of the rotating structure 200.

[0071] A portion of the first elastic element 230 is disposed within the first limiting groove 221. Thus, the first limiting groove 221 protects the first elastic element 230, thereby improving its service life and reliability. Simultaneously, it guides the compression or tension of the first elastic element 230, allowing it to compress or rebound along a predetermined axis. Furthermore, it facilitates pre-installation of the first elastic element 230, thereby improving the assembly efficiency of the steering structure.

[0072] Please continue reading. Figures 2-4 In some embodiments, a first mounting post 2211 is provided on the bottom wall of the first limiting groove 221. One end of the first elastic member 230 is sleeved on the first mounting post 2211. Therefore, when assembling the first elastic member 230, it can be first sleeved on the first mounting post 2211, which is a simple fixing method and helps to improve the assembly efficiency of the rotating structure 200.

[0073] Please continue reading. Figures 2-4 In some embodiments, the rotating structure 200 may further include a first sliding member 222. The first sliding member 222 is slidably connected to the first limiting groove 221. This arrangement allows the first sliding member 222 to slide relative to the first limiting groove 221.

[0074] For example, the first limiting groove 221 may have multiple slide rails 2212. These slide rails 2212 may be spaced apart on the sidewall of the first limiting groove 221. The first sliding member 222 may have multiple sliding protrusions 2222. The sliding protrusions 2222 protrude from the first sliding member 222 and slidably engage with the slide rails 2212. This arrangement simplifies the structure and facilitates the sliding engagement between the first sliding member 222 and the first limiting groove 221, thereby reducing the manufacturing cost of the rotating structure 200.

[0075] The cross-section of the first sliding member 222 can be rectangular, circular, or irregular in shape.

[0076] The first elastic element 230 is disposed between the bottom wall of the first sliding element 222 and the first limiting groove 221. Specifically, one end of the first elastic element 230 is located in the first limiting groove 221, and the other end is connected to the first sliding element 222. This provides better protection for the first elastic element 230, thereby helping to improve its service life.

[0077] Please continue reading. Figures 2-4 In some embodiments, the second rotating member 220 is provided with a first limiting groove 221, which is open on the side facing the first rotating member 210. In the first position S1, the first sliding member 222 abuts against the first rotating member 210, and the first elastic member 230 is in a compressed state. Specifically, during the rotation of the second rotating member 220 to the first position S1, one end of the first elastic member 230 is fixed within the first limiting groove 221, and the other end is connected to the first sliding member 222, ensuring that the first sliding member 222 is always in contact with the first rotating member 210, thus relatively fixing the first sliding member 222. The first limiting groove 221 slides relative to the first sliding member 222 towards the first rotating member 210, compressing the first elastic member 230 between the first limiting groove 221 and the first sliding member 222. This arrangement simplifies the structure and helps reduce the manufacturing cost of the rotating structure 200.

[0078] For example, the area where the first rotating member 210 abuts against the first sliding member 222 is called the first region. The orthographic projection of the first region onto the plane containing the first sliding member 222 lies within the contour of the first sliding member 222. Therefore, the dimension of the end of the first sliding member 222 facing the first rotating member 210 is larger than the dimension of the first region, giving the first sliding member 222 a larger abutting area. This allows the first sliding member 222 to better engage with the first rotating member 210, thereby ensuring that the first elastic member 230 can more reliably provide a restoring force to the second rotating member 220 when switching from the first position S1 to the third position S3.

[0079] Please continue reading. Figures 2-4 For example, the outer periphery of the open side of the first limiting groove 221 has a limiting protrusion 2213 that protrudes toward the first rotating member 210. The limiting protrusion 2213 is also located on the outer periphery of the first sliding member 222. Thus, the first sliding member 222 can be limited by the limiting protrusion 2213, which helps to avoid the problem of the first sliding member 222 falling off, and thus helps to improve the stability and reliability of the rotating structure 200.

[0080] Please continue reading. Figures 2-4In some embodiments, the first sliding member 222 may have a first mounting cavity 2221. The side of the first mounting cavity 2221 facing the bottom wall of the first limiting groove 221 is open. A portion of the first elastic member 230 is located in the first mounting cavity 2221. Thus, the first mounting cavity 2221 can better protect the first elastic member 230, thereby improving the service life of the first elastic member 230. At the same time, it also facilitates the assembly of the first elastic member 230, thereby improving the assembly efficiency of the rotating structure 200.

[0081] Please continue reading. Figures 2-4 In some embodiments, the rotating structure 200 includes a second elastic member 240. The second elastic member 240 is disposed between the first rotating member 210 and the second rotating member 220. Thus, when the first rotating member 210 and the second rotating member 220 rotate relative to each other, the second elastic member 240 can be compressed or stretched.

[0082] The second elastic element 240 is located on the other side of the first rotation center line W1 along the first direction F1. Therefore, when the second rotating element 220 rotates around the first rotation center line W1 to the first position S1 or the second position S2, a force can be applied to the second elastic element 240.

[0083] The second elastic element 240 is configured to provide a restoring force to the second rotating element 220 in the second position S2, switching towards the third position S3. Specifically, when the first elastic element 230 and the second rotating element 220 are on the same side of the first direction F1 in the first position S1, the first elastic element 230 is under compression, and the second elastic element 240 is under tension. When the first elastic element 230 and the second rotating element 220 are on different sides of the first direction F1 in the first position S1, the first elastic element 230 is under tension, and the second elastic element 240 is under compression.

[0084] Therefore, when the second rotating member 220 rotates around the first rotation center line W1 to the second position S2, the second elastic member 240 can provide a restoring force to the second rotating member 220 to switch to the third position S3, so that the second rotating member 220 can return from the second position S2 to the third position S3. Thus, when the second rotating member 220 is in the first position S1 or the second position S2, it can automatically switch back to the third position S3 through the restoring force provided by the first elastic member 230 or the second elastic member 240, which is conducive to further improving the user experience.

[0085] Please continue reading. Figures 2-4In some embodiments, the second elastic member 240 has the same stiffness as the first elastic member 230. This helps to reduce the assembly difficulty of the rotating structure 200. At the same time, the restoring forces on opposite sides of the second rotating member 220 are the same, allowing the second rotating member 220 to switch back to the third position S3 more stably.

[0086] The second elastic element 240 has a different stiffness than the first elastic element 230. This arrangement helps to improve the applicability of the rotating structure 200.

[0087] Please continue reading. Figures 2-4 For example, one of the second rotating member 220 and the first rotating member 210 is provided with a second limiting groove 223. The second limiting groove 223 is open to the other side of the second rotating member 220 and the first rotating member 210. Specifically, the second rotating member 220 may be provided with the second limiting groove 223, and the second limiting groove 223 may be open to the side of the first rotating member 210. Alternatively, the first rotating member 210 may be provided with the second limiting groove 223, and the second limiting groove 223 may be open to the side of the second rotating member 220.

[0088] A portion of the second elastic element 240 is disposed within the second limiting groove 223. Thus, the second elastic element 240 is protected by the second limiting groove 223, thereby improving its service life and reliability. Simultaneously, it provides guidance for the compression or tension of the second elastic element 240, allowing it to compress or rebound along a predetermined axis. Furthermore, it facilitates pre-installation of the second elastic element 240, thereby improving the assembly efficiency of the steering structure.

[0089] Please continue reading. Figures 2-4 For example, a second mounting post 2231 is provided on the bottom wall of the second limiting groove 223. One end of the second elastic member 240 is sleeved on the second mounting post 2231. Therefore, when assembling the second elastic member 240, it can be sleeved on the second mounting post 2231 first, which is a simple fixing method and helps to improve the assembly efficiency of the rotating structure 200.

[0090] Please continue reading. Figures 2-4 For example, the rotating structure 200 may further include a second slider 224. The second slider 224 is slidably connected to the second limiting groove 223. This arrangement allows the first slider 222 to slide relative to the second limiting groove 223.

[0091] The second elastic element 240 is disposed between the bottom wall of the second sliding element 224 and the second limiting groove 223. Specifically, one end of the second elastic element 240 is located in the second limiting groove 223, and the other end is connected to the first sliding element 222. This provides better protection for the second elastic element 240, thereby improving its service life.

[0092] Please continue reading. Figures 2-4 For example, the second rotating member 220 is provided with a second limiting groove 223, which is open on the side facing the first rotating member 210. In the second position S2, the second sliding member 224 abuts against the first rotating member 210, and the second elastic member 240 is in a compressed state. This arrangement simplifies the structure and helps to reduce the manufacturing cost of the rotating structure 200.

[0093] Please continue reading. Figures 2-4 For example, the second sliding member 224 may have a second mounting cavity 2241. The side of the second mounting cavity 2241 facing the bottom wall of the second limiting groove 223 is open. A portion of the second elastic member 240 is located in the second mounting cavity 2241. Thus, the second elastic member 240 can be better protected by the second mounting cavity 2241, thereby improving the service life of the second elastic member 240. At the same time, it also facilitates the assembly of the second elastic member 240, thereby improving the assembly efficiency of the rotating structure 200.

[0094] Please continue reading. Figures 2-4 In some embodiments, the second rotating member 220 may include a mounting portion 2201 and two rotating portions 2202. The mounting portion 2201 is adapted to connect to the fuselage, and the two rotating portions 2202 protrude from the mounting portion 2201. The two rotating portions 2202 are arranged opposite to each other in the extension direction of the first rotation center line W1. A portion of the first rotating member 210 is located between the two rotating portions 2202 and is rotatably connected to the two rotating portions 2202. Specifically, the cross-section of the second rotating member 220 perpendicular to the first direction F1 may be formed as an inverted U-shape. This avoids interference when the second rotating member 220 rotates relative to the first rotating member 210, thereby improving the reliability of the rotation of the rotating structure 200.

[0095] Along the arrangement direction of the mounting portion 2201 and the first rotating member 210, the first elastic member 230 is located between the mounting portion 2201 and the first rotating member 210. This facilitates the assembly of the first elastic member 230, thereby improving the assembly efficiency of the rotating structure 200. It also prevents the rotating portion 2202 from interfering with the compression or tension of the first elastic member 230.

[0096] Please continue reading. Figures 2-4In some embodiments, the end of the first rotating member 210 facing the mounting portion 2201 is provided with a first protrusion 211. Along the arrangement direction of the mounting portion 2201 and the first rotating member 210, the first protrusion 211 is directly opposite the first elastic member 230, and the first elastic member 230 is located between the mounting portion 2201 and the first protrusion 211. This arrangement helps to reduce the manufacturing cost of the rotating structure 200.

[0097] The cleaning device provided in another embodiment of this application will now be described. The difference between this embodiment and the above embodiment is that the position of the first elastic member 230 is different.

[0098] Please continue reading. Figures 1-4 In some embodiments, when the first elastic member 230 is in a stretched state at the first position S1, the first elastic member 230 and the wiping disc assembly 120 are located on opposite sides of the first rotation center line along the first direction F1. Therefore, when the first elastic member 230 is in a stretched state at the first position S1, it needs to recover its deformation, which will drive the second rotating member 220 to switch to the third position S3.

[0099] Please continue reading. Figures 1-4 In some embodiments, the rotating structure 200 further includes a second elastic member 240, which is disposed between the first rotating member 210 and the second rotating member 220, and located on the other side of the first rotation center line along the first direction F1. The second elastic member 240 is configured to provide a restoring force to the second rotating member 220 in the second position S2 to switch to the third position S3, and the stiffness of the first elastic member 230 is greater than the stiffness of the second elastic member 240. This allows for better cooperation with the floor brush 100 having the wiping assembly 120, enabling the machine body to switch back to the third position S3 more stably.

[0100] The cleaning device provided in another embodiment of this application will be described below.

[0101] Please return to the reference. Figure 1 and Figure 2 In some embodiments, the floor brush 100 includes a first wheel and a second wheel. Both the first and second wheels are rotatably mounted on the bottom of the housing 110, and are spaced apart in a first direction F1. The cleaning device also includes a detection device and an electronic control module. The electronic control module is electrically connected to the detector and adjusts the rotational speed of the first and second wheels based on the detection results from the detection device. Specifically, when the detection device detects that the second rotating member 220 rotates to one side around a first rotation center line, the electronic control module understands that the user has a tendency to rotate to one side, for example, to the left or right. The electronic control module then adjusts the rotational speed of the first and second wheels to cause the floor brush 100 to rotate to one side.

[0102] Please continue reading. Figure 1 In some embodiments, the detection device includes a first detection element and a second detection element. Both the first and second detection elements are disposed on the second rotating member 220. The first rotating member 210 has a first abutment portion and a second abutment portion. The rotating structure 200 has a first trigger position and a second trigger position. The first trigger position is either between the third position S3 and the first position S1, or the first position S1. The second trigger position is either between the third position S3 and the second position S2, or the second position S2.

[0103] At the first trigger position, the first detection element abuts against the first contact part, and the electronic control module controls the differential rotation of the first wheel and the second wheel based on the detection result of the first detection element. This allows the floor brush 100 to rotate in the first direction F1, which is the same side as the first trigger position, thereby improving the intelligence level of the cleaning equipment and ultimately enhancing the user experience.

[0104] At the second trigger position, the first detection element abuts against the second contact part, and the electronic control module controls the differential rotation of the first and second wheels based on the detection result of the second detection element. This allows the floor brush 100 to rotate in the direction of the first direction F1, which is the same side as the second trigger position, thereby improving the intelligence level of the cleaning equipment and ultimately enhancing the user experience.

[0105] It should be noted that the contact time between the first detection component and the first contacting part, and the contact time between the first detection component and the second contacting part, can be used to determine whether the user has made a mistake.

[0106] It is understood that in the various embodiments of this application, the sequence number of each process does not imply the order of execution.
