Technical Field

[0001] This application belongs to the field of cleaning equipment technology, specifically relating to a cleaning component and cleaning equipment. Background Technology

[0002] With the development of technology, cleaning equipment, such as robotic vacuum cleaners, has gradually entered people's lives. Cleaning equipment is a type of smart home. With a certain degree of artificial intelligence, it can automatically complete the floor cleaning work, bringing great convenience to people's lives.

[0003] Cleaning equipment uses cleaning components to clean the ground. However, existing cleaning equipment is not convenient to adjust the working status of the cleaning components during use. For example, it is not convenient to adjust the height of the working surface of the cleaning components, which makes it difficult for the cleaning components to switch to different cleaning heights.

[0004] Therefore, the related technology has the drawback that it is inconvenient to adjust the working state of the cleaning components when using the cleaning equipment. Utility Model Content

[0005] The purpose of this application is to provide a cleaning component and a cleaning device that can solve the problem in the related art that it is inconvenient to adjust the working state of the cleaning component when using the cleaning device.

[0006] In a first aspect, embodiments of this application provide a cleaning component, the cleaning component comprising:

[0007] A cleaning body is movably connected to the base of a cleaning device, and the cleaning body has a first working state and a second working state.

[0008] The drive assembly includes a drive motor and a rotating wheel connected to the drive motor. The rotating wheel is provided with a first drive part and a second drive part. The first drive part and the second drive part are distributed along the circumference of the rotating wheel. The distance between the second drive part and the rotation center of the rotating wheel is greater than the distance between the first drive part and the rotation center of the rotating wheel. The first drive part and the second drive part can act on the cleaning body respectively.

[0009] When the first driving unit acts on the cleaning body, the cleaning body switches to the first working state;

[0010] When the second drive unit acts on the cleaning body, the cleaning body switches to the second working state.

[0011] Secondly, embodiments of this application also provide a cleaning device, which includes a base and the aforementioned cleaning components. The cleaning body of the cleaning components is movably connected to the base, and the driving component of the cleaning components is disposed on the base.

[0012] In this embodiment, a drive motor drives a rotating wheel to rotate, thereby adjusting the positions of the first and second drive units. This allows either the first or second drive unit to act on the cleaning body, switching the cleaning body to either a first or second working state. This configuration allows the user to adjust the working state of the cleaning components via the drive assembly without manual intervention, improving ease of use and safety. Furthermore, the structure using a drive motor and rotating wheel to switch the cleaning body's working states is simple and easy to assemble, reducing the risk of malfunctions and maintenance costs associated with complex mechanical structures.

[0051] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0052] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0053] The cleaning components and cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0054] refer to Figures 1-27 This application provides a cleaning component that may include a cleaning body 100 and a drive component 200. The cleaning body 100 can be movably connected to a base 300 of a cleaning device, and may have a first working state and a second working state. The drive component 200 may include a drive motor 210 and a rotating wheel 220 connected to the drive motor 210. The rotating wheel 220 may be provided with a first drive part 221 and a second drive part 222. The first drive part 221 and the second drive part 222 may be distributed circumferentially along the rotating wheel 220. The distance between the second drive part 222 and the rotation center of the rotating wheel 220 may be greater than the distance between the first drive part 221 and the rotation center of the rotating wheel 220. Furthermore, the first drive part 221 and the second drive part 222 may act on the cleaning body 100 respectively.

[0055] When the first drive unit 221 acts on the cleaning body 100, the cleaning body 100 switches to the first working state; when the second drive unit 222 acts on the cleaning body 100, the cleaning body 100 switches to the second working state.

[0056] In this embodiment, the rotating wheel 220 is rotated by the drive motor 210 to adjust the position of the first drive unit 221 and the second drive unit 222, so that the first drive unit 221 or the second drive unit 222 acts on the cleaning body 100, thereby switching the cleaning body 100 to the first working state or the second working state. With this configuration, the user can adjust the working state of the cleaning component through the drive assembly 200 during use without manual intervention, which improves the convenience and safety of use. At the same time, the structure of the drive motor 210 and the rotating wheel 220 cooperating to drive the cleaning body 100 to switch working states is simple in structure and easy to assemble, which helps reduce the failure and maintenance costs caused by complex mechanical structures.

[0057] In an optional embodiment, the working surface of the cleaning body 100 in the first working state is lower than that in the second working state. That is, when the first drive unit 221 acts on the cleaning body 100, the cleaning body 100 switches to the first working state, which lowers the cleaning body 100 to a low position, thus switching the cleaning body 100 to a pressurized mode. This allows the cleaning body 100 to perform pressurized cleaning on carpets and the like, thereby cleaning hair or impurities from the carpet fibers and improving the cleaning effect. When the second drive unit 222 acts on the cleaning body 100, the cleaning body 100 switches to the second working state, which raises the cleaning body 100 to a normal cleaning position. Here, the first working state can be a pressurized working state, and the second working state can be a normal cleaning state. In this embodiment, the raising and lowering of the working surface of the cleaning body 100 can be achieved by adjusting the positions of the first drive unit 221 and the second drive unit 222.

[0058] In an optional embodiment of this application, the cleaning body 100 may also have a third working state, and the rotating wheel 220 may also be provided with a third driving unit 223. Here, the third driving unit 223, the first driving unit 221, and the second driving unit 222 may be distributed circumferentially along the rotating wheel 220, and the distance between the third driving unit 223 and the rotation center of the rotating wheel 220 may be greater than the distance between the second driving unit 222 and the rotation center of the rotating wheel 220. When the third driving unit 223 acts on the cleaning body 100, the cleaning body 100 switches to the third working state. With this configuration, the cleaning body 100 can be switched to the third working state by the third driving unit 223, thereby improving the functionality of the cleaning equipment.

[0059] In other embodiments, the cleaning body 100 may not have a third working state, and the rotating wheel 220 may not include the third drive unit 223.

[0060] Optionally, the working surface of the cleaning body 100 in the third working state can be higher than the working surface of the cleaning body 100 in the second working state. When the third drive unit 223 acts on the cleaning body 100, the cleaning body 100 switches to the third working state, which can raise the cleaning body 100 to a high position, that is, the cleaning body 100 can switch to the lifting mode. In this way, the cleaning body 100 can clean a higher surface to be cleaned, or the cleaning body 100 can avoid obstacles, or the cleaning body 100 can be lifted off the ground to facilitate disassembly of the cleaning body 100.

[0061] In an optional embodiment, the cleaning body 100 can be a roller brush cavity assembly, which may include a scraper 130, a roller brush cavity 101, and a roller brush 120. The roller brush cavity 101 can be movably connected to the base 300, the roller brush 120 is disposed within the roller brush cavity 101, and the scraper 130 can be disposed below the roller brush 120. Figure 10 and Figure 11 As shown, when the cleaning body 100 is in the second working state, the scraper 130 interferes with the surface A to be cleaned by 0.3mm, that is, the scraper 130 is compressed by 0.3mm, so that the scraper 130 can press firmly against the ground, thereby improving the cleaning effect; as Figure 8 and Figure 9 As shown, when the cleaning body 100 is in its first working state, under its own weight, the cleaning body 100 presses down on objects such as blankets, allowing the bottom end of the scraper 130 to extend under the surface A to be cleaned, for example, into the blanket or other object, thereby improving the cleaning effect; Figure 12 and Figure 13 As shown, when the cleaning body 100 is in the third working state, the cleaning body 100 rises to the high position and moves the scraper 130 away from the surface A to be cleaned. At this time, the distance between the scraper 130 and the surface A to be cleaned can be 3mm.

[0062] Of course, the cleaning body 100 may not be a roller brush chamber assembly. For example, the cleaning body 100 may be a mop disc assembly or other cleaning structures.

[0063] In some embodiments, the roller brush chamber assembly may further include a roller brush motor 170, two roller brush cover plates 102, and a counterweight 190. The roller brush motor 170 is disposed on the side of the roller brush chamber 101 opposite to the scraper strip 130, and is connected to the roller brush 120 via a transmission structure. The transmission structure may be disposed at one end of the roller brush chamber 101, and the counterweight 190 may be disposed at the other end of the roller brush chamber 101. The two roller brush cover plates 102 may respectively cover both ends of the roller brush chamber 101, and may respectively cover the transmission structure and the counterweight 190. The cavity 101 is provided with a dust inlet mounting frame 150, which is connected to the roller brush cavity 101 via a flexible element 160. Here, the flexible element 160 can be made of liquid silicone. The dust inlet mounting frame 150 has a roller brush cavity dust inlet 151 communicating with the roller brush cavity 101. The dust inlet mounting frame 150 can be installed at the dust inlet mounting position 320 on the base 300. The roller brush cavity 101 can communicate with the suction port of the cleaning equipment's fan, and the roller brush cavity dust inlet 151 can communicate with the dust box on the base 300 to suck dust and other contaminants into the dust box. The dust inlet mounting frame 150 can be connected to the base 300 via screws. Specifically, the dust inlet mounting frame 150 has mounting holes 152 for screws to pass through.

[0064] Furthermore, the cleaning body 100 can be rotatably connected to the base 300 via two pivots 180, and the two pivots 180 can be respectively positioned near both ends of the cleaning body 100 to improve the stability of the cleaning body 100. Here, the base 300 can be provided with pivot mounting holes 310, and the pivots 180 can be connected to the pivot mounting holes 310.

[0065] Optionally, the roller brush chamber assembly may also include a flexible baffle 140, which may be disposed below the base 300 and on one side of the roller brush chamber 101. The flexible baffle 140 may prevent large debris from entering the roller brush chamber 101 and causing the roller brush 120 to jam.

[0066] In some embodiments, the cleaning body 100 may also have multiple working states, such as a fourth working state, a fifth working state, etc. Correspondingly, the rotating wheel 220 may also be provided with multiple driving parts, such as a fourth driving part, a fifth driving part, etc., and the distance between each driving part and the rotation center of the rotating wheel 220 is not equal. In this way, the cleaning body 100 can switch between multiple working states, thereby further improving the functionality of the cleaning equipment.

[0067] It should be noted that when switching working states, there is no need to use other sensors for position detection. The position of each drive unit can be switched directly by rotating the rotating wheel 220, thereby directly switching the cleaning body to the required working state.

[0068] In an optional embodiment, the rotating wheel 220 may include a rotating wheel body 2201 and a connecting portion 2202. The connecting portion 2202 is coaxially disposed with the rotating wheel body 2201. The connecting portion 2202 may be located on the side of the rotating wheel body 2201 near the motor body of the drive motor 210, and the connecting portion 2202 may be in a circumferential upper limit engagement with the output shaft 211 of the drive motor 210, so that the rotating wheel 220 can rotate synchronously with the output shaft 211 of the drive motor 210. In this embodiment, the first driving portion 221, the second driving portion 222, and the third driving portion 223 may all be disposed on the rotating wheel body 2201.

[0069] Here, at least one first limiting surface 212 can be provided on the output shaft 211 of the drive motor 210, and a connecting hole 2203 connected to the output shaft 211 is provided on the connecting part 2202. At least one second limiting surface 2204 can be provided on the hole wall of the connecting hole 2203. The first limiting surface 212 and the second limiting surface 2204 fit together so that the connecting part 2202 and the output shaft 211 are in a circumferential limiting fit.

[0070] The first limiting part 224 and the second limiting part 225 can both be connected to the connecting part 2202, and the first limiting part 224 and the second limiting part 225 can both be connected to the side of the rotating wheel body 2201 that is close to the motor body of the drive motor 210. In this way, the structural strength of the first limiting part 224 and the second limiting part 225 can be further improved.

[0071] In addition, the reinforcing part 226 mentioned above can also be connected to the side of the rotating wheel body 2201 that is close to the motor body of the drive motor 210. In this way, the structural strength of the reinforcing part 226 can be improved, which in turn helps to further improve the structural strength of the first limiting part 224 and the second limiting part 225.

[0072] In an optional embodiment of this application, a connecting working plate 110 is provided on the cleaning body 100, and a rotating wheel 220 is located below the connecting working plate 110. When the first driving part 221 abuts against the connecting working plate 110, the cleaning body 100 switches to a first working state; when the second driving part 222 abuts against the connecting working plate 110, the cleaning body 100 switches to a second working state; and when the third driving part 223 abuts against the connecting working plate 110, the cleaning body 100 switches to a third working state. With this configuration, since the rotating wheel 220 is located below the connecting work plate 110, the first drive unit 221, the second drive unit 222, and the third drive unit 223 can abut against the connecting work plate 110. By adjusting the positions of the first drive unit 221, the second drive unit 222, and the third drive unit 223, the cleaning body 100 can be raised and lowered. Furthermore, it is easier for the drive assembly 200 to drive the cleaning body 100. At the same time, the first drive unit 221, the second drive unit 222, or the third drive unit 223 can provide support for the cleaning body 100, making it easier for the cleaning body 100 to maintain the required working state.

[0073] In other embodiments, the cleaning body 100 may not have a connecting work plate 110, and the output shaft 211 of the drive motor 210 may be parallel to the length direction of the cleaning body 100. The first drive unit 221, the second drive unit 222 and the third drive unit 223 may directly contact the cleaning body 100, and the cleaning body 100 may be kept in the required working state by the friction between the drive unit and the cleaning body 100.

[0074] Optionally, the cleaning body 100 may also be provided with at least two reinforcing plates 111, each of which can be connected to the connecting work plate 110. This can strengthen the connection between the connecting work plate 110 and the cleaning body 100 and improve the structural strength of the connecting work plate 110.

[0075] Of course, the reinforcing plate 111 may not be installed on the main cleaning unit 100.

[0076] Alternatively, along the direction from the rotating wheel 220 to the connecting work plate 110, i.e. from bottom to top, the width of each reinforcing plate 111 gradually increases in the direction from the cleaning body 100 to the drive motor 210. This increases the connection area between the reinforcing plate 111 and the connecting work plate 110, thereby improving the connection strength between the connecting work plate 110 and the reinforcing plate 111. Furthermore, the at least two reinforcing plates 111 mentioned above may include two first reinforcing plates 1111 and at least two second reinforcing plates 1112. The two first reinforcing plates 111 may be connected to the two ends of the connecting working plate 110 along the length of the cleaning body 100, respectively. Each second reinforcing plate 1112 is located between the two first reinforcing plates 1111. In the direction from the cleaning body 100 to the drive motor 210, the maximum width of the first reinforcing plate 1111 is greater than or equal to the width of the connecting working plate 110 to improve the support strength of the first reinforcing plate 1111 to the connecting working plate 110. In the direction from the cleaning body 100 to the drive motor 210, the maximum width of the second reinforcing plate 1112 is less than the width of the connecting working plate 110 to provide space for the rotating wheel 220 to extend into. Of course, the at least two reinforcing plates 111 mentioned above may also include only the first reinforcing plate 1111 or the second reinforcing plate 1112.

[0077] In an optional embodiment, the first drive unit 221 is an arc-shaped surface, and the center of the arc-shaped surface coincides with the axis of the rotating wheel 220. This configuration facilitates the processing of the first drive unit 221. At the same time, since the first drive unit 221 is an arc-shaped surface, any position on the arc-shaped surface acting on the cleaning body 100 can switch the cleaning body 100 to the first working state, thereby increasing the effective area of ​​the first drive unit 221 and reducing the control precision of the rotating wheel 220.

[0078] Of course, the first drive unit 221 may not be a curved surface. For example, the first drive unit 221 may be a protrusion provided on the rotating wheel 220.

[0079] Furthermore, the central angle of the arc surface is greater than 0 and less than or equal to 183.5°. Optionally, the central angle of the arc surface can be equal to 183.5°. This setting allows the first drive unit 221 to act on the cleaning body 100 within the 183.5° range of the rotating wheel 220, that is, the cleaning body 100 can be in the first working state within the 183.5° range of the rotating wheel 220.

[0080] Based on the cleaning components provided in the embodiments of this application, the embodiments of this application also provide a cleaning device. The cleaning device may include a base 300 and the cleaning components described in any of the above embodiments. The cleaning body 100 of the cleaning component is movably connected to the base 300, and the driving component 200 of the cleaning component may be disposed on the base 300.

[0081] The beneficial effects achieved by the cleaning equipment provided in this application embodiment are consistent with the beneficial effects achieved by the cleaning components provided in this application embodiment, and will not be repeated here.

[0082] In an optional embodiment, the cleaning device may further include a limiting post 240, which may be connected to the base 300 or the drive motor 210. A first limiting part 224 may also be provided on the rotating wheel 220, which may be connected to the second drive part 222. When the second drive part 222 acts on the cleaning body 100, the first limiting part 224 and the limiting post 240 engage in a limiting cooperation in the direction from the third drive part 223 to the second drive part 222. This configuration, through the limiting cooperation between the first limiting part 224 and the limiting post 240, prevents the rotating wheel 220 from rotating in the direction from the third drive part 223 to the second drive part 222. This allows the second drive part 222 to accurately act on the cleaning body 100 and maintain the cleaning body 100 in a second working state, thereby preventing the cleaning body 100 from switching states due to external forces during operation.

[0083] Of course, the cleaning equipment may not include the limiting post 240, and the first limiting part 224 may not be provided on the rotating wheel 220.

[0084] In an optional embodiment, the rotating wheel 220 may also be provided with a second limiting part 225, which can be connected to the third driving part 223. When the third driving part 223 acts on the cleaning body 100, the second limiting part 225 and the limiting post 240 engage in a limiting cooperation in the direction from the second driving part 222 to the third driving part 223. With this configuration, the limiting cooperation between the second limiting part 225 and the limiting post 240 prevents the rotating wheel 220 from rotating in the direction from the second driving part 222 to the third driving part 223. This allows the third driving part 223 to act accurately on the cleaning body 100 and keep the cleaning body 100 in the third working state, thereby preventing the cleaning body 100 from switching states due to external forces during operation.

[0085] Of course, the second limiting part 225 may not be provided on the rotating wheel 220.

[0086] Optionally, at least one of the first limiting part 224 and the second limiting part 225 is provided with an arc-shaped limiting surface 227, which can fit against the side wall of the limiting post 240. This design has two advantages. First, because the arc-shaped limiting surface 227 fits against the side wall of the limiting post 240, the contact area between the first limiting part 224 and / or the second limiting part 225 and the limiting post 240 can be increased, effectively preventing the first limiting part 224 or the second limiting part 225 from shaking or moving, thereby improving the limiting effect between the first limiting part 224 and / or the second limiting part 225 and the limiting post 240. Second, the arc-shaped limiting surface 227 can play a certain buffering role when the first limiting part 224 and / or the second limiting part 225 contacts the limiting post 240, thereby reducing the impact force on the rotating wheel 220 and the limiting post 240, and reducing the wear between the first limiting part 224 and / or the second limiting part 225 and the limiting post 240, thus helping to extend the service life of the rotating wheel 220 and the limiting post 240.

[0087] In this embodiment, both the first limiting part 224 and the second limiting part 225 may be provided with an arc-shaped limiting surface 227, and the curvature directions of the arc-shaped limiting surface 227 of the first limiting part 224 and the arc-shaped limiting surface 227 of the second limiting part 225 are opposite.

[0088] Of course, the first limiting part 224 and the second limiting part 225 may not have the arc-shaped limiting surface 227.

[0089] Optionally, a reinforcing portion 226 is provided between the first limiting portion 224 and the second limiting portion 225, with both ends of the reinforcing portion 226 connected to the first limiting portion 224 and the second limiting portion 225, respectively. This arrangement can improve the strength of the first limiting portion 224 and the second limiting portion 225, preventing them from deforming or breaking due to excessive force.

[0090] Of course, the reinforcing part 226 may not be provided between the first limiting part 224 and the second limiting part 225.

[0091] In an optional embodiment, the drive assembly 200 may further include a motor bracket 230, through which the drive motor 210 can be connected to the base 300, and the aforementioned limiting post 240 can be disposed on the motor bracket 230. This arrangement facilitates the processing of the limiting post 240 and eliminates the need to modify the base 300.

[0092] Optionally, a connecting post can be provided on the base 300, and a mounting hole can be provided on the motor bracket 230. The connecting post can extend into the mounting hole, thereby realizing the connection between the motor bracket 230 and the base 300.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
