[0001] The utility model relates to the technical field of cleaning equipment, in particular to a side sweeping component and a cleaning device. Background Art

[0002] As a new type of cleaning appliance, sweeping robots and cleaning base stations are particularly popular among users because of their practical functions such as self-cleaning, automatic garbage dumping, and automatic recharging. They are very convenient to use.

[0003] When a sweeping robot or a cleaning base station performs a cleaning operation, a side sweeping assembly is usually provided to clean the edge of the space. When working, the side sweeping assembly is driven to rotate by a motor. However, the current side sweeping assembly mainly includes a side sweeping body and a cleaning arm provided on the periphery of the side sweeping body. During the rotation of the side sweeping assembly, hair is easily entangled on the cleaning arm, and the hair is easily moved along the cleaning arm and entangled on the side sweeping body and the rotating shaft of the motor. This easily causes the side sweeping body and the rotating shaft to be unable to rotate, thereby causing the motor to be blocked and burn out. Utility Model Content

[0004] The main purpose of the utility model is to provide a side sweeping assembly and a cleaning device to solve the problem that the side sweeping assembly in the prior art easily causes the motor to burn out.

[0005] According to one aspect of the utility model, there is provided a side scanning assembly, comprising:

It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] As mentioned in the background technology, the existing side sweeper assembly mainly includes a side sweeper body and a cleaning arm arranged on the periphery of the side sweeper body. During the rotation of the side sweeper assembly, hair is easily entangled on the cleaning arm, and the hair is easily moved along the cleaning arm and entangled on the side sweeper body and the rotating shaft of the motor, which easily causes the side sweeper body and the rotating shaft to be unable to rotate, thereby causing the motor to be blocked and burn out. To this end, the utility model provides a new side sweeper assembly, which can solve the problem that the structure of the side sweeper assembly in the prior art is easy to cause the motor to burn out. The side sweeper assembly of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 3 As shown, according to an embodiment of the present application, a side sweeping assembly is provided, which includes a main body 10 , a support arm 20 and a cleaning arm 30 .

[0036] Specifically, the support arm 20 includes at least one, and the first end of the support arm 20 is connected to the main body 10; the cleaning arm 30 includes at least one, at least one support arm 20 and at least one cleaning arm 30 are arranged in a one-to-one correspondence, the first end of the cleaning arm 30 is connected to the second end of the support arm 20, and the interconnected cleaning arm 30 and the support arm 20 have different extension directions, that is, the cleaning arm 30 and the support arm 20 extend along different straight lines.

[0037] When the side sweeping assembly of the present application is installed on a cleaning device, such as a cleaning robot or a cleaning base station, the motor 40 (such as Figure 5The cleaning arm 30 is connected to the main body 10 and drives the main body 10 to rotate, thereby driving the support arm 20 and the cleaning arm 30 to rotate synchronously. When the cleaning arm 30 rotates, the edge of the space can be cleaned. At the same time, since the support arm 20 is arranged between the cleaning arm 30 and the main body 10 in this embodiment, when hair is entangled on the cleaning arm 30, the arrangement of the support arm 20 can extend the distance between the cleaning arm 30 and the main body 10, and prevent the hair on the cleaning arm 30 from directly contacting the main body 10 and entangled on the main body 10 and the rotating shaft of the motor 40; at the same time, since the connecting cleaning arm 30 and the support arm 20 extend in different directions, when the hair is entangled on the cleaning arm 30, the support arm 20 can play a blocking role between the cleaning arm 30 and the main body 10, and the hair on the cleaning arm 30 is difficult to be entangled on the support arm 20 and then contact the main body 10 and entangled on the main body 10 and the rotating shaft of the motor 40.

[0038] That is to say, in this embodiment, by arranging the support arm 20 between the cleaning arm 30 and the main body 10, and making the extension direction of the support arm 20 different from the extension direction of the cleaning arm 30, such an arrangement can prevent the hair entangled on the cleaning arm 30 from bypassing the support arm 20 and entangled on the main body 10 and the rotating shaft of the motor 40 used to drive the main body 10 to rotate, thereby preventing the motor 40 from being blocked and burned. Compared with the side sweeping assembly in the prior art, the main body 10 of the side sweeping assembly in this embodiment is not easily entangled by hair, and the problem of the motor 40 rotating shaft being blocked and burned can be avoided. It is safer to use and can increase the service life of the cleaning device using the side sweeping assembly in this embodiment.

[0039] Combine again Figures 1 to 3 As shown, the main body 10 in this embodiment is generally arranged in a columnar block structure, and the columnar block can be a cylindrical block, a prismatic block or other special-shaped column blocks, etc. Figures 1 to 3 1 shows the case where the main body 10 is arranged as a cylindrical block structure. In actual connection, the support arm 20 is connected to the outer edge of the cylindrical block.

[0040] In order to improve the structural strength and service life of the side sweeping assembly in this embodiment, the support arm 20 and the main body 10 in this embodiment are processed by integral injection molding, and the structure is stable and reliable. Of course, in other embodiments of the present application, the support arm 20 and the main body 10 can also be connected by screw connection, welding or clamping, etc. As long as other deformation methods are based on the conception of this application, they are all within the scope of protection of this application.

[0041] Likewise, the cleaning arm 30 and the supporting arm 20 in this embodiment may be connected by means of snap connection, welding, screw connection or integral injection molding.

[0042] Furthermore, the support arm 20 in the present embodiment can be arranged in a cylindrical shape or in a block shape, and the cross-sectional area of ​​the support arm 20 (i.e., the cross-sectional area obtained by cutting the support arm 20 along the length direction perpendicular to the support arm 20) gradually decreases in the direction away from the main body 10, that is, the end of the support arm 20 close to the main body 10 is relatively thick, and the end away from the main body 10 is relatively thin. Such an arrangement can make the center of gravity of the support arm 20 arranged toward the side close to the main body 10, so as to avoid the support arm 20 from being separated from the main body 10 under the action of centrifugal force when the side sweeping assembly rotates, and can improve the use stability and reliability of the side sweeping assembly in the present embodiment to a certain extent. Of course, in other embodiments of the present application, the cross-sectional area of ​​the support arm 20 can also remain unchanged along the length direction of the support arm 20.

[0043] Optionally, the corners of the second end of the support arm 20 in this embodiment are provided with chamfered corners 22. With this arrangement, when the side-sweeping assembly rotates, the corners of the second end of the support arm 20 can be prevented from damaging objects in the space, and the support arm 20 can be prevented from scratching the human body during the assembly process.

[0044] See also Figure 1 As shown, the support arm 20 in this embodiment extends in the radial direction of the main body 10. After the cleaning arm 30 is connected to the second end of the support arm 20, compared with the extension of the support arm 20 in other directions, the support arm 20 in this embodiment is Figure 1 , the first end of the cleaning arm 30 is farthest from the main body 10 , and the hair on the cleaning arm 30 is less likely to be entangled on the main body 10 .

[0045] Furthermore, a stopper 21 is provided between the first end of the cleaning arm 30 and the second end of the supporting arm 20 in the present embodiment. Through the action of the stopper 21, the hair can be stopped on the cleaning arm 30 to prevent the hair on the cleaning arm 30 from moving to the supporting arm 20 and the main body 10, which can further improve the safety of the side sweeping assembly in the present embodiment.

[0046] Optionally, the stopper 21 in this embodiment includes a stopper protrusion 211, which is arranged on the support arm 20 and protrudes from at least the outer edge of the first end of the cleaning arm 30. In this way, the hair wrapped around the cleaning arm 30 is not easy to bypass the stopper protrusion 211 and wrap around the support arm 20 and the main body 10. Optionally, the stopper protrusion 211 in this embodiment is integrally formed with the support arm 20. In actual processing, it is only necessary to make the second end of the support arm 20 protrude from the outer periphery of the cleaning arm 30. The structure is simple and easy to implement.

[0047] Of course, in other embodiments of the present application, the stop portion 21 can also be other structures such as a stop block welded, screwed or clamped on the second end of the support arm 20 or the first end of the cleaning arm 20. As long as it is other deformation methods based on the concept of the present application, it is within the protection scope of the present application.

[0048] In this embodiment, the cleaning arm 30 is a bundle of bristles or a cleaning strip. In the embodiment of the present application, a bristle structure is preferably used. A bundle of bristles includes multiple bristles, and the first ends of the multiple bristles are fixedly connected as a whole, that is, the bristles are an integral structure. This arrangement can prevent the brushes from merging and picking up hairs when the cleaning arm 30 opens and contacts the ground and leaves the ground. There is a first angle A between the support arm 20 and the cleaning arm 30. The first angle A is greater than or equal to 90° and less than or equal to 150°. That is to say, the first angle A in this embodiment satisfies the relationship: 90°≤A≤150°, for example, 90°, 100°, 110°, 120°, 130°, 140° or 150°, etc. When the first angle A is less than 90°, the second end of the cleaning arm 30 will be arranged toward the main body 10, which makes it inconvenient to clean the edge of the space, and the hair is easy to contact the main body 10; when the first angle A is greater than 150°, as the main body 10 rotates, the hair on the cleaning arm 30 is easy to pass over the cleaning arm 30 and entangle on the support arm 20. That is to say, in this embodiment, by making the first angle A satisfy the relationship: 90°≤A≤150°, not only can the cleaning effect of the side sweeping assembly be guaranteed, but also the hair on the cleaning arm 30 can be prevented from being entangled on the support arm 20 and the main body 10.

[0049] Combination Figures 1 to 5 As shown, in order to facilitate the connection with the rotating shaft of the motor 40, the main body 10 in this embodiment is provided with a connecting portion 11 for connecting with a predetermined rotating shaft (i.e., the rotating shaft of the motor 40), and the extension line of the cleaning arm 30 and the center line of the connecting portion 11 (i.e., the line coinciding with the axis of the rotating shaft of the motor 40) are staggered. When the main body 10 rotates, the hair on the cleaning arm 30 is wound around the cleaning arm 30 along the length direction of the cleaning arm 30. In this application, by staggering the extension line of the cleaning arm 30 and the center line of the connecting portion 11, the winding direction of the hair can be deviated from the center line of the connecting portion 11 on the main body 10, which can further prevent the hair from moving toward the side close to the main body 10 and winding around the rotating shaft of the main body 10 and the motor 40, thereby further preventing the rotating shaft of the motor 40 from being blocked and burned. Exemplarily, the connecting portion 11 can be a connecting hole or a connecting groove, etc.

[0050] Furthermore, the cleaning arm 30 in this embodiment includes an anti-static arm, that is, the cleaning arm 30 in this embodiment has an anti-static effect, so that the cleaning arm 30 can be prevented from rubbing against the hair to generate static electricity and adsorb the hair on the cleaning arm 30. Exemplarily, the anti-static arm includes a rubber arm or a plastic arm, which has a simple structure and low manufacturing cost.

[0051] Combination Figure 2 As shown, the main body 10 has a first side 101 (with Figure 2 The support arms 20 and the cleaning arms 30 each include a plurality of support arms 20 and a plurality of cleaning arms 30, and the plurality of support arms 20 and the plurality of cleaning arms 30 are arranged at intervals along the outer periphery of the main body 10, and the plurality of support arms 20 and the plurality of cleaning arms 30 are all located on the first side 101 of the main body 10. In this embodiment, the support arms 20 and the cleaning arms 30 can be arranged in two, three, four or more than four. Figures 1 to 3 2 shows the case where there are three support arms 20 and cleaning arms 30. By providing multiple support arms 20 and multiple cleaning arms 30, the cleaning effect and cleaning efficiency of the side sweep assembly in the embodiment can be improved. At the same time, in the embodiment, by making multiple support arms 20 and multiple cleaning arms 30 all located on the first side 101 of the main body 10, when the side sweep assembly is installed in the cleaning device, the first side 101 is the side close to the ground. Such a configuration can make the cleaning arm 30 fit the bottom surface as much as possible, so as to facilitate cleaning the ground.

[0052] In combination with the above embodiments, it can be known that the side sweeping assembly of the present application includes a main body 10, a support arm 20 and a cleaning arm 30. Since the support arm 20 is arranged between the cleaning arm 30 and the main body 10, the extension direction of the support arm 20 is different from the extension direction of the cleaning arm 30, and the support arm 20 is provided with a stopper 21, the cleaning stop can be realized to prevent the hair on the cleaning arm 30 from moving toward the side close to the main body 10. At the same time, the cleaning arm 30 has an antistatic effect, which can prevent the cleaning arm 30 from rubbing with the hair to generate static electricity and adsorb the hair, and the cleaning arm 30 is an integral structure. Compared with the brush structure, the brush can be prevented from merging and picking up hair in the process of leaving the ground after the brush is opened and touched the ground, thereby avoiding the need for the user to manually clean the side sweeping, and at the same time, under the blocking effect of the support arm 20, it can be prevented that the hair rises along the cleaning arm 30 to the main body 10 and the rotating shaft of the motor 40 to cause the motor 40 to burn.

[0053] See also Figure 4 and Figure 5As shown, according to another aspect of the present application, the present application further provides a cleaning device, which may be, for example, a sweeping robot, or a cleaning base station, etc. The cleaning device includes the side sweeping component in the above embodiment, and therefore, the cleaning device includes all the technical effects of the side sweeping component in the above embodiment. Since the technical effects of the side sweeping component have been described in detail above, they will not be repeated here.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
