Description

Technical Field

[0001] This application relates to the field of cleaning robot technology, and in particular to an anti-tangling side brush and a sweeping robot. Background Technology

[0002] Robotic vacuum cleaners are equipped with roller brushes and side brushes, with the side brushes typically located on the side of the robot near the bottom. During cleaning, the roller brush and side brushes work together to increase the cleaning coverage area and enhance the cleaning depth. The side brushes can also be used to clean edge areas or corners, such as those next to walls or obstacles.

[0003] The side brush of a robotic vacuum cleaner generally consists of a side brush frame and side brush legs. The side brush legs are fixed to the side brush frame. In traditional robotic vacuum cleaners, the side brush legs are set to correspond to the diameter of the side brush frame, which makes it easy for debris to be blown away by the side brush legs and for hair and other debris to get tangled at the connection between the side brush frame and the side brush legs. Utility Model Content

[0004] This application provides an anti-tangling side brush and a sweeping robot, aiming to solve the problem that the diameter setting of the side brush legs corresponding to the side brush frame of traditional sweeping robots makes it easy for garbage to be blown away by the side brush legs and for hair and other debris to get tangled at the connection between the side brush frame and the side brush legs.

[0005] To solve the above-mentioned technical problems, this application proposes an anti-tangling side brush, which includes: a side brush frame and side brush legs;

[0006] The side brush leg is provided in two parts, and the two side brush legs are fixed on the same side of the side brush frame, and the side brush leg and the outer contour of the side brush frame are tangent to each other.

[0007] Furthermore, the two side brush legs are arranged in parallel with a spacing between them.

[0008] Furthermore, the brush skeleton is hemispherical.

[0009] Furthermore, the side brush leg includes a fixing strip, which is fixedly connected to the side brush frame, and the fixing strip is curved.

[0010] Furthermore, the side brush leg also includes a brush, and a first mounting groove is provided at the end of the fixing strip away from the side brush frame, and the brush is fixed in the first mounting groove.

[0011] Furthermore, the fixing strip is twisted.

[0012] Furthermore, the anti-tangling side brush also includes a connecting component, the side brush frame is provided with a second mounting groove, the connecting component is disposed in the second mounting groove, and the connecting component is used to connect an external driving device.

[0013] Furthermore, the connecting component includes a first connector, the side brush frame is provided with a first through groove, the first connector is embedded in the first through groove, and the first connector is fixedly assembled with the side brush frame.

[0014] Furthermore, the connecting assembly also includes a second connector, the second connector having a third mounting groove, the first connector being embedded in the third mounting groove, and the first connector and the second connector being fixedly assembled.

[0015] In order to achieve the above-mentioned utility model objectives, the second aspect of this utility model provides a sweeping robot, which includes the anti-tangling side brush of any of the above-mentioned components.

[0016] The beneficial effects of this application are as follows: In the anti-tangling side brush and sweeping robot provided in this application, the anti-tangling side brush includes a side brush frame and side brush legs. Two side brush legs are provided, fixed to the same side of the side brush frame, and the side brush legs are tangent to the outer contour of the side brush frame. Because the side brush legs are tangent to the outer contour of the side brush frame, the side brush legs are less likely to scatter debris during operation, and hair and other debris are less likely to become tangled at the connection between the side brush legs and the side brush frame.

[0025] like Figure 1 As shown, this application provides an anti-tangling side brush, which includes a side brush frame 100 and side brush legs 200. There are two side brush legs 200, which are fixed to the same side of the side brush frame 100, and the side brush legs 200 and the outer contour of the side brush frame 100 are in a tangent positional relationship.

[0026] In one specific embodiment, the side brush frame 100 plays a crucial role in supporting the various components. The shape and material of the side brush frame 100 are determined according to actual design requirements. The side brush legs 200 are the structural parts that directly participate in the cleaning work. By contacting the ground or other cleaning surfaces, they achieve the collection and sweeping of dust and debris. In this embodiment, two side brush legs 200 are provided, and the two side brush legs 200 are fixed on the same side of the side brush frame 100. This layout makes the force on the anti-tangling side brush relatively concentrated on one side during operation, which facilitates the drive device to rotate and clean it. The tangential position of the side brush legs 200 and the outer contour of the side brush frame 100 means that the installation position of the side brush legs 200 is exactly along the tangential direction of the edge of the side brush frame 100. This makes it less likely that hair, thread-like debris, etc., will become entangled at the junction of the side brush legs 200 and the side brush frame 100 during the rotation of the anti-tangling side brush. Instead, they are more likely to be thrown off the side brush legs 200 under the action of centrifugal force, effectively reducing entanglement and ensuring that the anti-tangling side brush can continue to perform cleaning work smoothly. Furthermore, the structural design of the side brush legs 200 being tangent to the outer contour of the side brush frame 100 makes it less likely that the anti-tangling side brush will fly debris during rotation.

[0027] In summary, the tangential design of the side brush legs 200 and the outer contour of the side brush frame 100 effectively improves the problem of traditional side brushes easily getting tangled with hair and other debris, while also reducing the chance of the side brush legs 200 scattering debris.

[0028] like Figure 1 As shown, the two side brush legs 200 are arranged in parallel at intervals.

[0029] In one specific embodiment, the two side brush legs 200 are parallel to each other and there is a certain distance between them. Because the two side brush legs 200 are parallel, the debris wrapped around the two side brush legs 200 is more easily detached from the side brush legs 200 under the action of centrifugal force. Furthermore, the distance between the two side brush legs 200 allows each side brush leg 200 to play its own role during the cleaning process, avoiding mutual interference.

[0030] like Figure 1 As shown, the brush skeleton 100 is hemispherical.

[0031] In one specific embodiment, the side brush frame 100 adopts a hemispherical shape. Structurally, it has a unique curved surface and spatial form. The curved surface of the side brush frame 100 provides a suitable curvature for the installation of the side brush legs 200, allowing the side brush legs 200 to be fixed along the curved surface in a reasonable positional relationship such as tangency. Moreover, the hemispherical shape makes it easier for debris and dust to slide off the curved surface or be thrown off by centrifugal force when the anti-tangling side brush rotates and cleans. Compared with some flat or other shaped frames, the hemispherical shape reduces the probability of debris staying and accumulating on the side brush frame 100. At the same time, the hemispherical structure has good spatial inclusiveness, which can adapt to side brush legs 200 of different lengths and shapes as well as different installation layouts, providing a good foundation for the diversified design and functional optimization of the entire anti-tangling side brush.

[0032] like Figure 2 As shown, the side brush leg 200 includes a fixing strip 210, which is fixedly connected to the side brush frame 100, and the fixing strip 210 is curved.

[0033] In one specific embodiment, the fixing strip 210, as an important component of the side brush leg 200, serves to connect the side brush frame 100 and the brush 220. Its material needs to possess sufficient strength and toughness to ensure that the side brush leg 200 will not easily break or deform during prolonged rotating cleaning operations. In this embodiment, the fixing strip 210 and the side brush frame 100 are integrally formed. The curved shape of the fixing strip 210 allows the brush 220 to better conform to the terrain when contacting the ground or other surfaces being cleaned. For example, when cleaning surfaces with a certain slope or unevenness, the curved fixing strip 210 allows the brush 220 to contact the ground at a more suitable angle, enhancing the cleaning effect. From an anti-tangling perspective, the curved shape changes the straight shape of the fixing strip 210. When debris, hair, etc., come into contact with the side brush leg 200, they are less likely to quickly accumulate and entangle along the direction of the fixing strip 210; instead, they are obstructed at the bend. Compared to traditional straight fixing strips, this more effectively prevents tangling.

[0034] In summary, the curved design of the fixing strip 210 in the side brush leg 200 optimizes the performance of the anti-tangling side brush. When cleaning large areas with complex ground conditions, such as outdoor plazas and parks, cleaning equipment equipped with this anti-tangling side brush can better adapt to ground conditions. Whether the ground is slightly uneven or has small potholes, the curved fixing strip 210 can guide the brush 220 to closely adhere to the ground, effectively sweeping away dust, leaves, and other debris. At the same time, when dealing with easily tangled debris such as pet hair and plant fibers, the curved fixing strip 210 effectively reduces the probability of these debris getting tangled on the side brush leg 200.

[0035] like Figure 3 As shown, the side brush leg 200 also includes a brush 220. The end of the fixing strip 210 away from the side brush frame 100 is provided with a first mounting groove 211, and the brush 220 is fixed in the first mounting groove 211.

[0036] In one specific embodiment, the brush 220 is a key component that directly contacts the surface being cleaned to achieve the cleaning function. Its material is typically soft and possesses a certain degree of elasticity and friction, such as nylon filaments, which effectively adsorbs and removes dust and other fine debris. The first mounting groove 211 is located at the end of the fixing strip 210 away from the side brush frame 100, and its shape and size match the brush 220. By installing the brush 220 in the first mounting groove 211, it is ensured that the brush 220 will not easily loosen or fall off during rotating cleaning, thus ensuring the stability of the cleaning operation. Simultaneously, through the reasonable design of the depth, width, and other dimensional parameters of the first mounting groove 211, the extension length and angle of the brush 220 can be adjusted to a certain extent, allowing the brush 220 to better adapt to different cleaning scenarios and requirements, further optimizing the cleaning effect.

[0037] In summary, the side brush leg 200 uses a first mounting groove 211 at one end of the fixing strip 210 to fix the brush 220, allowing workers to easily and promptly replace worn brushes 220, ensuring the side brush always maintains good cleaning performance. Furthermore, this design allows for adjustment of the brush 220's extension length and angle, enabling the anti-tangling side brush to be optimized and adjusted according to actual conditions when cleaning different floor materials, improving adaptability to various floor surfaces and enhancing cleaning effectiveness.

[0038] like Figure 2 As shown, the fixing strip 210 is twisted.

[0039] In one specific embodiment, the twisted shape of the fixing strip 210 is a further optimization design based on the curved shape. Here, the twisted shape means that the fixing strip 210 undergoes a spiral twist along its length, and different fixing strips 210 have different twist angles. From an anti-tangling perspective, when debris, hair, etc., come into contact with the twisted fixing strip 210, due to its spiral structure, the debris will be dispersed along the twisting direction, making it difficult to form a continuous entanglement along the fixing strip 210. Furthermore, under the centrifugal force generated by the rotation of the anti-tangling side brush, it is easier to be thrown away from the side brush leg 200. From a cleaning function perspective, the twisted fixing strip 210 allows the brush 220 to contact the surface being cleaned from multiple different angles during the cleaning process, enhancing the cleaning ability of the anti-tangling side brush.

[0040] In summary, the twisted design of the fixing strip 210 significantly improves the overall performance of the anti-tangling side brush. The twisted fixing strip 210 effectively handles various easily tangled filamentous and thread-like debris, ensuring the anti-tangling side brush can operate stably for extended periods. Simultaneously, its unique multi-angle cleaning function provides better cleaning results for stubborn stains and small debris on the floor. Furthermore, the twisted fixing strip 210 makes the side brush leg 200 structure more resilient and resistant to deformation, extending the service life of the side brush leg 200.

[0041] like Figure 3 As shown, the anti-tangling side brush also includes a connecting component 300. The side brush frame 100 is provided with a second mounting groove 110, and the connecting component 300 is disposed in the second mounting groove 110. The connecting component 300 is used to connect an external driving device.

[0042] In one specific embodiment, the connecting component 300 is a key part for connecting the anti-tangling side brush to the drive device. It plays a role in transmitting power, enabling the anti-tangling side brush to rotate and perform cleaning work under the drive device. The side brush frame 100 is a hollow hemispherical shape, and its hollow part is the second mounting groove 110. The second mounting groove 110 provides a stable and suitable mounting space for the connecting component 300, ensuring the stability and reliability of power transmission. The connecting component 300 can be composed of multiple different parts, such as slots, bushings, etc. Through the cooperation of these structures, it can accurately dock with the drive device.

[0043] like Figure 2 As shown, the connecting component 300 includes a first connector 310, and the side brush frame 100 is provided with a first through groove 120, in which the first connector 310 is embedded.

[0044] In one specific embodiment, the bottom of the side brush frame 100 is provided with a first through groove 120, which extends through the side brush frame 100 and is circular. The first connecting member 310 includes a first cylindrical portion 311 and a second cylindrical portion 312, which are integrally formed and concentrically arranged. The diameter of the first cylindrical portion 311 is smaller than the diameter of the second cylindrical portion 312, and the shape of the first cylindrical portion 311 matches the shape of the first through groove 120. The first cylindrical portion 311 is embedded in the first through groove 120.

[0045] like Figure 3 As shown, the connecting component 300 also includes a second connector 320, which has a third mounting groove 321, and the first connector 310 is embedded in the third mounting groove 321.

[0046] In one specific embodiment, the shape of the second connector 320 matches the shape of the second mounting groove 110. The second connector 320 is located in the second mounting groove 110. The side of the second connector 320 near the first connector 310 is provided with a third mounting groove 321. The shape of the third mounting groove 321 matches the shape of the second cylindrical portion 312. The second cylindrical portion 312 is embedded in the third mounting groove 321, so that the first connector 310 and the second connector 320 are fixedly connected. This nested design forms a tight and orderly connection relationship between the first connector 310 and the second connector 320.

[0047] A fourth mounting groove 322 is provided at the end of the second connector 320 away from the first connector 310. The fourth mounting groove 322 is used to connect with an external drive device. The fourth mounting groove 322 and the third mounting groove 321 are concentrically arranged to ensure the balance and stability of the entire connecting assembly 300 during the force and power transmission process. This allows the power transmitted from the drive device to be evenly and smoothly transmitted to the side brush frame 100 through the connecting assembly 300, avoiding additional vibration, skewing and other adverse conditions caused by uneven force. The shape and size of the fourth mounting groove 322 are designed according to the specifications of common drive device output shafts and other connection parts. In this embodiment, the fourth mounting groove 322 is a rectangular groove.

[0048] In order to achieve the purpose of this utility model, in one embodiment, this application also provides a sweeping robot, which includes the anti-tangling side brush described in any of the above embodiments.

[0049] In this embodiment, no specific structure of the robot vacuum cleaner is limited, as long as the robot vacuum cleaner includes the aforementioned anti-tangling side brush.

[0050] The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
