Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cleaning systems, and particularly relates to a sweeping robot and a cleaning system. BACKGROUND
[0002] The side brush is an indispensable component of the sweeping robot. When the sweeping robot is working, the side brush rotates at high speed to drive the bristles to rotate, effectively sweeping the garbage at the corners and the roots of obstacles and the like to the cleaning range of the roller brush. Subsequently, the roller brush or the vacuum cleaning device further cleans the garbage, ensuring that the corners can be thoroughly cleaned.
[0003] In the related art, most side brushes are always in contact with the surface to be cleaned. When the surface to be cleaned has viscous stains such as liquid dirt, oil stains and dust, the stains will come into contact with the side brush, causing the side brush to be contaminated. The contaminated side brush will bring the stains to the originally clean surface to be cleaned when it continues to clean, causing secondary pollution. When the sweeping robot passes through the carpet, the side brush will pull and entangle the carpet fibers, which not only damages the carpet but also increases the noise and energy consumption when traveling. CONTENT OF THE UTILITY MODEL

[0015] In some embodiments, the side brush arm further extends away from the rotation direction.
[0016] In some embodiments, the side brush device comprises a driving module and an outward swinging module, the driving module is installed in the shell, a first end of the outward swinging module is rotationally connected to the driving module, and a second end of the outward swinging module is rotationally connected to the side brush arm, and the driving module is used to drive the second end of the outward swinging module to swing between the lifting area and the circumferential side of the shell.
[0017] In some embodiments, the side brush arm further extends away from the rotation direction, and the rotation direction of the outward swinging module is the same as the rotation direction of the side brush arm when the outward swinging module swings into the lifting area.

When an element is referred to as being "fixedly connected" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element.
[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the specification herein is for describing particular embodiments only and is not intended to be limiting of the application.
[0040] In order to better understand the technical solutions and beneficial effects of the present application, the present application will be further described in detail below in combination with specific embodiments:
[0041] As shown in Figures 1 to 3 An embodiment of the floor cleaning robot 10 includes a housing 100, an edge brush device 200, and a receiving cover 300. The housing 100 is provided with a lifting area 101 adjacent to one side of the surface to be cleaned. The edge brush device 200 is mounted on the housing 100, and the edge brush device 200 is provided with an edge brush arm 210 arranged to rotate, the edge brush arm 210 is arranged to tilt towards the surface to be cleaned, and the edge brush arm 210 is used to sweep the garbage at the corner into the cleaning range of the roller brush. The receiving cover 300 is located in the lifting area 101 and cooperates with the receiving cover 300 to form a receiving cavity 301, that is, the receiving cavity 301 is formed between the receiving cover 300 and the housing 100, the receiving cavity 301 extends to the outside of the housing 100, the edge brush arm 210 can enter the receiving cavity 301 and abut against the receiving cover 300, so that the edge brush arm 210 elastically deforms towards the housing 100 and is lifted, and the edge brush arm 210 is separated from the surface to be cleaned after being lifted, so that the edge brush arm 210 is switched to the stowed position. Preferably, the receiving cover 300 is plate-shaped.
[0042] As shown in Figure 2It is shown that, in the present embodiment, the reference distance of each element is the distance between the corresponding element and the surface to be cleaned, one end of the brush arm 210 away from the surface to be cleaned is the first end, and the other end of the brush arm 210 close to the surface to be cleaned is the second end. When the brush arm 210 is in contact with the surface to be cleaned, the reference distance of the accommodation cover 300 is less than the reference distance of the first end of the brush arm 210, and the reference distance of the accommodation cover 300 is greater than the reference distance of the second end of the brush arm 210. Before the brush arm 210 passes through the adhesive stain or the carpet, the brush arm 210 enters the accommodation cavity 301 and abuts against the accommodation cover 300, so that the brush arm 210 is elastically deformed towards the shell 100 under the abutting force F of the accommodation cover 300, and then the brush arm 210 is lifted and separated from the surface to be cleaned, that is, the brush arm 210 is lifted to the stowed position. When the brush arm 210 needs to be cleaned again, the brush arm 210 leaves the accommodation cavity 301, so that the brush arm 210 is elastically reset, that is, the brush arm 210 is lowered to the cleaning position.
[0043] It can be understood that, in the process of the brush arm 210 entering the accommodation cavity 301, the accommodation cover 300 slides relative to the brush arm 210, and at the same time pushes the brush arm 210 to deform towards the shell 100, and then the brush arm 210 is lifted. The relative sliding of the accommodation cover 300 and the brush arm 210 does not limit which element is moving and which element is stationary, and the relative sliding means that there is a speed difference between the brush arm 210 and the accommodation cover 300, resulting in sliding between them.
[0044] It can be understood that the number of brush arms 210 is not limited, and the number of brush arms 210 can be 1, 2, 3, 4, etc. Each brush arm 210 has bristles, and the number of bristles on each brush arm 210 is not limited, and the number of bristles on each brush arm 210 can be 1, 2, 3, 4, etc.
[0045] It should be noted that the lifting of the present application is a movement away from the surface to be cleaned, and is not limited to vertical upward movement. For example, when the robot cleaner 10 cleans the wall surface, the lifting is a movement away from the wall surface; when the robot cleaner 10 cleans the ground, the lifting is a movement away from the ground.
[0046] The above-described robot cleaner 10, before the brush arm 210 passes through the adhesive stain or the carpet, the brush arm 210 enters the accommodation cavity 301 between the accommodation cover 300 and the shell 100, and abuts against the accommodation cover 300, so that the brush arm 210 is elastically deformed towards the shell 100 and lifted to a predetermined height, and the brush arm 210 is separated from the surface to be cleaned after being lifted, avoiding the situation that the brush arm 210 contacts the adhesive stain or the carpet, improving the cleaning effect of the robot cleaner 10, avoiding damage to the carpet by the brush arm 210, and reducing noise and energy consumption when traveling.
[0047] Furthermore, after the side brush arm 210 enters the receiving cover 300, the receiving cover 300 covers one side of the side brush arm 210, so that the receiving cover 300 protects the side brush arm 210, reduces the chance of external damage to the side brush arm 210, extends the service life of the side brush arm 210, and avoids the side brush arm 210 from coming into contact with sticky stains, carpets, etc.
[0048] like Figure 3 As shown, in some embodiments, the side brush arm 210 also extends away from its rotation direction A. That is, the direction C in which the side brush arm 210 extends from the first end to the second end is away from its rotation direction A, wherein the first end of the side brush arm 210 is disposed adjacent to the outward swing module 230, and the second end of the side brush arm 210 is disposed away from the outward swing module 230. Figure 3 For example, the rotation direction A is counterclockwise, and the extension direction C is clockwise or close to clockwise. In this way, the receiving cover 300 can abut against the side brush arm 210 along the extension direction of the side brush arm 210, reducing the bending angle of the side brush arm 210 and preventing the side brush arm 210 from breaking when entering the receiving cavity 301. This also allows the side brush arm 210 to return to its original position after being raised, ensuring that the side brush arm 210 can be repeatedly cleaned and raised.
[0049] like Figure 3 As shown, in some embodiments, the housing cover 300 is fixedly connected to the housing 100, omitting the drive structure of the housing cover 300, simplifying the structure of the sweeping robot 10 and reducing the cost of the sweeping robot 10.
[0050] like Figure 4 As shown, in this embodiment, when it is necessary to lift the side brush arm 210, the side brush arm 210 moves toward the lifting area 101. At this time, the side brush arm 210 enters the receiving cavity 301 and abuts against the receiving cover 300, causing the side brush arm 210 to elastically deform toward the housing 100 and lift. After being lifted, the side brush arm 210 separates from the surface to be cleaned, so that the side brush arm 210 switches to the retracted position.
[0051] like Figure 5 As shown, in some other embodiments, the housing 100 is provided with an idle area 102 on the side adjacent to the surface to be cleaned, and the receiving cover 300 is movably disposed between the lifting area 101 and the idle area 102. When the receiving cover 300 is in the idle area 102, it can be completely separated from the side brush arm 210.
[0052] like Figure 6As shown, in this embodiment, when the side brush arm 210 needs to be raised, the receiving cover 300 moves to the lifting area 101, forming a receiving cavity 301 between the receiving cover 300 and the housing 100, allowing the side brush arm 210 to enter the receiving cavity 301 and abut against the receiving cover 300. When the side brush arm 210 is cleaning, the receiving cover 300 moves to the idle area 102, completely separating the receiving cover 300 from the side brush arm 210. This ensures that the side brush arm 210 does not lift during each rotation cycle, meaning the side brush arm 210 can continuously contact the surface to be cleaned during cleaning, improving the cleaning effect of the side brush arm 210. It can be understood that the movement of the receiving cover 300 can be linear motion, rotation, or flipping.
[0053] It is understandable that the raised area 101 and the idle area 102 can be partially overlapped, adjacent, or spaced apart.
[0054] like Figure 6 As shown, in some embodiments, the sweeping robot 10 also includes a drive unit 400, which is mounted on the housing 100. The receiving cover 300 is fixedly connected to the power output end of the drive unit 400. The drive unit 400 is used to drive the receiving cover 300 to switch between the lifting area 101 and the idle area 102, so that the receiving cover 300 can automatically switch positions, thus realizing the automation of the receiving cover 300.
[0055] It is understood that the driving device can be a linear driving device, a tilting driving device, a rotary driving device, or other existing driving devices. Preferably, the driving device is a linear driving device.
[0056] like Figure 6 As shown, in some embodiments, the rotation center of the side brush arm 210 is fixed to the lifting area 101. When the receiving cover 300 is in the lifting area 101, it coincides with one end of the side brush arm 210 adjacent to the housing 100. When the receiving cover 300 moves into the lifting area 101, it pushes the side brush arm 210, causing the side brush arm 210 to elastically deform towards the housing 100. In this embodiment, as the receiving cover 300 gradually enters the lifting area 101, it gradually forms a receiving cavity 301 with the housing 100, pushing the side brush arm 210 to elastically deform and lift towards the housing 100. After the receiving cover 300 is fully inside the lifting area 101, it coincides with one end of the side brush arm 210 adjacent to the housing 100, keeping the receiving cover 300 in contact with the side brush arm 210, thereby keeping the side brush arm 210 within the receiving cavity 301 and in the lifted position.
[0057] It should be emphasized that after the receiving cover 300 is fully inserted into the lifting area 101, since the receiving cover 300 overlaps with the end of the side brush arm 210 adjacent to the housing 100, even if the side brush arm 210 continues to rotate, the receiving cover 300 can still abut against the side brush arm 210, so that the side brush arm 210 remains in the lifting position.
[0058] like Figure 7 As shown, in some embodiments, the side brush device 200 includes a drive module 220 and an external swing module 230. The drive module 220 is installed inside the housing 100. The first end of the external swing module 230 is rotatably connected to the drive module 220, and the side brush arm 210 is rotatably connected to the second end of the external swing module 230. The drive module 220 is used to drive the second end of the external swing module 230 to swing between the lifting area 101 and the periphery of the housing 100, so that the drive module 220 can drive the second end of the external swing module 230 to extend to the periphery of the housing 100. Since the side brush arm 210 is rotatably connected to the second end of the external swing module 230, the cleaning range of the side brush arm 210 on the periphery of the housing 100 is increased, thereby improving the cleaning effect of the sweeping robot 10.
[0059] like Figure 7 As shown, in some embodiments, the side brush device 200 includes a drive module 220 and an outward swing module 230. The drive module 220 is installed inside the housing 100. The first end of the outward swing module 230 is rotatably connected to the drive module 220, and the side brush arm 210 is rotatably connected to the second end of the outward swing module 230. The drive module 220 is used to drive the second end of the outward swing module 230 to swing between the lifting area 101 and the periphery of the housing 100. Further, the housing 100 also has an idle area 102 on the side adjacent to the surface to be cleaned. A receiving cover 300 is movably disposed between the lifting area 101 and the idle area 102. When the receiving cover 300 is in the idle area 102, it can be completely separated from the side brush arm 210. In this embodiment, the lifting action of the side brush arm 210 has at least the following two types:
[0060] like Figure 7 As shown, in the first scenario: First, the second end of the outward-swinging module 230 is inserted into the lifting area 101. Then, the receiving cover 300 moves to the lifting area 101. As the receiving cover 300 gradually enters the lifting area 101, it gradually forms a receiving cavity 301 with the housing 100, pushing the side brush arm 210 to elastically deform and lift towards the housing 100. After the receiving cover 300 is fully inserted into the lifting area 101, the receiving cover 300 and the end of the side brush arm 210 adjacent to the housing 100 overlap, keeping the receiving cover 300 and the side brush arm 210 in contact, thereby keeping the side brush arm 210 within the receiving cavity 301 and in the lifted position.
[0061] like Figure 8As shown, the second method is as follows: First, the receiving cover 300 moves to the lifting area 101, and then the second end of the outward swing module 230 swings into the lifting area 101, so that the outward swing module 230 drives the side brush arm 210 into the receiving cavity 301 and abuts against the receiving cover 300, so that the side brush arm 210 elastically deforms and lifts towards the housing 100. After being lifted, the side brush arm 210 separates from the surface to be cleaned, so that the side brush arm 210 switches to the retracted position.
[0062] like Figure 4 As shown, in some embodiments, the side brush device 200 includes a drive module (not shown) and an outward swing module 230. The drive module is installed inside the housing 100. The first end of the outward swing module 230 is rotatably connected to the drive module, and the side brush arm 210 is rotatably connected to the second end of the outward swing module 230. The drive module is used to drive the second end of the outward swing module 230 to swing between the lifting area 101 and the periphery of the housing 100. Further, the receiving cover 300 is fixedly connected to the housing 100. In this embodiment, when the second end of the outward swing module 230 swings into the lifting area 101, the outward swing module 230 drives the side brush arm 210 into the receiving cavity 301 and abuts against the receiving cover 300, causing the side brush arm 210 to elastically deform and lift towards the housing 100. After lifting, the side brush arm 210 separates from the surface to be cleaned, allowing the side brush arm 210 to switch to the retracted position.
[0063] like Figure 7 As shown, furthermore, the side brush arm 210 extends away from its rotation direction A. That is, the direction C in which the side brush arm 210 extends from its first end to its second end is away from its rotation direction A. The first end of the side brush arm 210 is located adjacent to the outward swing module 230, and the second end of the side brush arm 210 is located away from the outward swing module 230. The rotation direction B of the outward swing module 230 when it swings into the lifting area 101 is the same as the rotation direction A of the side brush arm 210. Figure 7 For example, rotation directions A and B are both counterclockwise, while extension direction C is clockwise or nearly clockwise. This allows the receiving cover 300 to abut against the side brush arm 210 along its extension direction, reducing the bending angle of the side brush arm 210 and preventing it from breaking when entering the receiving cavity 301. This also ensures the side brush arm 210 can return to its original position after being raised, allowing for repeated cleaning and raising.
[0064] In some embodiments, the edge of the receiving cover 300 is provided with a plurality of spaced-apart combing sections (not shown), which are used to comb the side brush arm 210, thereby removing hair from the side brush arm 210 and improving the cleaning effect when the side brush arm 210 is cleaned again. Preferably, the plurality of combing sections are arranged in an array.
[0065] The application also provides a cleaning system, comprising a base station and the sweeping robot 10 of any of the above embodiments, the base station being used for accommodating the sweeping robot 10.
[0066] Compared with the prior art, the application has at least the following advantages:
[0067] 1. Before the side brush arm 210 passes through the sticky dirt and the carpet, the side brush arm 210 enters the accommodation cavity 301 between the accommodation cover 300 and the shell 100 and abuts against the accommodation cover 300, so that the side brush arm 210 is elastically deformed towards the shell 100 and is lifted to a predetermined height, the side brush arm 210 is separated from the surface to be cleaned after being lifted, the situation that the side brush arm 210 contacts the sticky dirt and the carpet is avoided, the cleaning effect of the sweeping robot 10 is improved, the carpet is prevented from being damaged by the side brush arm 210, and the noise and energy consumption during travel are reduced.
[0068] 2. After the side brush arm 210 enters the accommodation cover 300, the accommodation cover 300 covers one side of the side brush arm 210, so that the accommodation cover 300 plays a protective role on the side brush arm 210, the probability that the side brush arm 210 is damaged from the outside is reduced, the service life of the side brush arm 210 is prolonged, and the situation that the side brush arm 210 contacts the sticky dirt, the carpet and the like is avoided.
[0069] The above-described embodiments only express several embodiments of the application, the description is more specific and detailed, but it cannot be understood as a limitation on the disclosed patent scope. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which all belong to the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
