Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and a side brush assembly. Background Technology

[0002] During the cleaning process of a robot vacuum cleaner, the side brush component always works close to the ground. When it encounters dirt containing liquid, it is easy to spread the dirt onto the cleaned area, causing secondary pollution.

[0003] In related technologies, the side brush assembly is connected to a transmission component, which drives the side brush assembly to move up and down, thereby enabling selective operation. However, this method requires a large vertical travel space, which is insufficient at the bottom of the robot vacuum, necessitating an increase in the robot's height to achieve the aforementioned functions. Utility Model Content

[0004] The purpose of this application is to provide a cleaning device and a side brush assembly that can raise and lower the cleaning component without increasing the height of the cleaning device, so that the cleaning component can selectively perform cleaning operations.

[0005] To achieve the above objectives, this application provides a side brush assembly, which includes a support base, a rotating body, and a cleaning component. The support base includes a transmission component and a housing connected to each other. The rotating body has a spiral mechanism on its outer peripheral surface. The cleaning component has a leg section and a cleaning section. The leg section is connected to the housing via a rotating component. One end of the leg section is connected to the cleaning section, and the other end of the leg section can slide relative to the spiral mechanism, so that the leg section drives the cleaning section to move up and down relative to the support base.

[0006] Optionally, the spiral mechanism is a spiral groove, the rotating body is sleeved on the transmission member, and the other end of the support leg section is held in the spiral groove. When the bearing seat rotates in the first direction, the housing rotates relative to the rotating body, and the other end of the support leg section slides towards the bottom of the spiral groove, causing the cleaning section to flip upward so that the end of the cleaning section moves upward.

[0007] Optionally, the side brush assembly includes: a bracket; a unidirectional rotating member having an outer ring fixedly connected to the bracket and an inner ring rotatable in one direction relative to the outer ring in a second direction; the second direction being opposite to the first direction; and a mating sleeve, the outer wall surface of which is connected to the inner ring of the unidirectional rotating member, and the inner wall surface of which is connected to the rotating body.

[0008] Optionally, the outer wall surface of one end of the rotating body is formed with an external hexagonal surface, and the spiral groove is formed on the outer wall surface of the other end of the rotating body; the inner wall surface of the mating sleeve is formed with an internal hexagonal surface, and when the upper part of the rotating body is inserted into the interior of the mating sleeve, the external hexagonal surface and the internal hexagonal surface mate.

[0009] Optionally, the bottom end of the rotating body abuts against the housing.

[0010] Optionally, the housing has a side extension and an outer extension, wherein the side extension extends radially outward from the bottom periphery of the transmission member, and the outer extension extends upward from the periphery of the side extension; a clearance hole is provided on the side of the outer extension, and the support leg extends into the spiral groove through the clearance hole.

[0011] Optionally, the side brush assembly further includes a top cover, wherein the top cover is connected to the top end of the outer extension, the top cover has a through hole, the rotating body passes through the through hole and extends partially into the area formed by the transmission member, the housing and the top cover, and the spiral groove is located in the area formed by the transmission member, the housing and the top cover.

[0012] To achieve the above objectives, this application also provides a cleaning device, which includes at least a moving body, a driving component, and the aforementioned side brush assembly. The side brush assembly is disposed at the bottom of the cleaning device, and the driving component drives the side brush assembly to rotate.

[0013] Optionally, the side brush assembly further includes a drive assembly, which includes a power source and a transmission gear, wherein the power source drives the transmission component to rotate through the transmission gear.

[0014] Optionally, the transmission component is provided with an upward-facing mounting groove; the drive assembly further includes a drive rod, which is connected to the transmission gear and inserted into the mounting groove.

[0015] Optionally, the drive assembly further includes a transmission assembly, wherein the bracket surrounds to form a receiving cavity, and the transmission assembly, the one-way rotating member, the mating sleeve, and the transmission gear are disposed within the receiving cavity.

[0016] Therefore, the technical solution provided in this application involves a transmission component that drives the cleaning component to rotate via the housing. The cleaning component is connected to the housing via a rotating component, and the other end of the support leg of the cleaning component can slide along a spiral mechanism. When the housing and the rotating body rotate relative to each other, the other end of the cleaning component can slide up and down under the guidance of the spiral mechanism, allowing the cleaning section connected to one end of the cleaning component to rotate up and down around the rotating component. In this way, when liquid waste is detected, the cleaning section can automatically lift, thereby avoiding secondary pollution caused by contamination of the side brush.

[0017] Furthermore, it is understandable that the housing and the rotating body achieve the vertical adjustment of the cleaning section through relative rotation. During the adjustment process, the vertical position of the housing and the rotating body does not change, and there is no need for vertical adjustment stroke space. Therefore, the cleaning equipment does not need to increase its own height to reserve a large bottom space for installing the side brush assembly. Thus, the cleaning component can be raised and lowered without increasing the height of the cleaning equipment, allowing the cleaning component to be selectively cleaned, and the cleaning equipment can be made as thin as possible to expand the range of low-lying areas that can be cleaned.

[0032] As robotic vacuum cleaners become increasingly popular, users are demanding higher levels of intelligence and deep cleaning capabilities. Adding side brushes to the bottom edge of robotic vacuum cleaners increases cleaning coverage and enhances corner cleaning ability. However, these side brushes also present some challenges, such as affecting the robot's ability to overcome obstacles and spreading solid-liquid mixtures or wastewater onto cleaned areas.

[0033] To address this, this application integrates a side brush adjustment structure within the side brush assembly. Utilizing the forward and reverse rotation of the motor driving the side brush assembly, the side brush can be raised and lowered. This allows the brush bristles to be lifted when encountering obstacles or liquid-containing dirt, improving obstacle-crossing ability and cleaning effectiveness. Furthermore, the side brush bristle raising and lowering function of this application can also raise the bristles to avoid easily tangled dust and hair, preventing entanglement.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0035] like Figure 1 and Figure 2As shown, this application provides a cleaning device that may include a movable body 100, a side brush assembly 200, and a drive assembly 300. The movable body 100 serves as the main body of the cleaning device, primarily supporting and protecting other components. The side brush assembly 200 is connected to the bottom of the movable body 100, moving along with it. The drive assembly 300 can also drive the side brush assembly 200 to rotate, allowing it to perform self-rotation cleaning while moving with the movable body 100. This enables the cleaning device to increase cleaning coverage and enhance the cleaning ability of corners and edges through the side brush assembly 200.

[0036] In practical applications, the mobile unit 100 can be a self-moving chassis, capable of autonomous movement according to a preset program. The mobile unit 100 can also be a semi-automatic unit, equipped with auxiliary movement functions and a handheld handle for easy user pushing, allowing for manual movement in conjunction with the auxiliary movement functions. Of course, the mobile unit 100 can also be entirely user-driven. In other words, the cleaning equipment can be, for example, a robotic vacuum cleaner, a floor scrubber, or a handheld cleaning device.

[0037] Regarding the specific structure of the side brush component 200, as follows: Figures 3 to 5 As shown, in one feasible embodiment, the side brush assembly 200 may include a bracket 210 connected to the movable body 100, a support 220, and a cleaning component 230. The support 220 has a transmission component 221 and a housing, with the housing located at the bottom end of the transmission component 221. A drive assembly 300 is connected to the transmission component 221, allowing the drive assembly 300 to drive the transmission component 221 and the housing to rotate. The cleaning component 230 is arranged around the axis of the transmission component 221 and has a leg section 231 and a cleaning section 232. The leg section 231 is connected to the housing via a rotating component 233, and the end of the leg section 231 away from the transmission component 221 is connected to the cleaning section 232. When the drive assembly 300 drives the housing to rotate, the housing can drive the cleaning component 230 to rotate, thereby using the cleaning section 232 to clean the ground. Preferably, the rotating part 233 of the housing is located near the end of the support leg section 231 adjacent to the transmission part 221. In this way, the end of the support leg section 231 near the transmission part 221 only needs to move up and down slightly to drive the cleaning part 230 to move up and down significantly, thereby enabling rapid adjustment of the cleaning part 230. Furthermore, there is no need to reserve too much space inside the housing, thus reducing the volume of the housing.

[0038] In this embodiment, the vertical movement of the end of the support leg segment 231 adjacent to the transmission component 221 is adjusted, thereby causing the end of the support leg segment 231 away from the transmission component 221 to drive the cleaning segment 232 to rotate up and down around the rotating component 233. In other words, adjusting the vertical movement of the cleaning segment 232 enables it to have a lifting function. When liquid debris is detected, or when the scene requires a mopping mode and the sweeping mode is not desired, the cleaning segment 232 can automatically lift to avoid contamination. Thus, in sweeping mode, if liquid stains are encountered, the cleaning segment 232 will not come into contact with the ground, thereby avoiding secondary pollution caused by dirt on the side brush.

[0039] Furthermore, it is understandable that in scenarios where the cleaning equipment also has a mopping function, the cleaning equipment can also achieve a single mopping function. That is, in the single mopping mode, the cleaning section 232 can be automatically raised and transformed into a pure mopping cleaning equipment. This can avoid the cleaning section 232 from being coated with wet stains, and achieve the separation of sweeping and mopping in the cleaning process and the separation of dry and wet pollutants.

[0040] In practical applications, the support leg section 231 can be made of a high-rigidity material such as plastic or hard rubber, so that the cleaning section 232 can be rotated and flipped through the support leg section 231. The cleaning section 232 can be made of a flexible material such as bristles, so that the cleaning section 232 can deform and fit into contact with the ground, thereby improving the cleaning effect of the cleaning section 232 on the ground.

[0041] In one feasible implementation, a rotating body 250 may be included, which is sleeved on the transmission member 221. A helical mechanism is provided on the outer wall surface of the rotating body 250. This helical mechanism can be a helical groove 251, a helical protrusion, or other helically sliding structure; this application does not specifically limit its application. Taking the helical groove 251 as an example, the helical groove 251 is arranged around the axis of the rotating body 250. The end of the support leg segment 231 away from the cleaning segment 232 remains within the helical groove 251. Along the axial direction of the rotating body 250, the rotating member 233 is rotatably connected to the housing via a rotating shaft and is located near the clearance hole. Thus, when the rotating body 250 and the support seat 220 rotate relative to each other, the end of the support leg segment 231 away from the cleaning segment 232 can move up and down under the limiting action of the helical groove 251, thereby causing the end of the support leg segment 231 away from the transmission member 221 to drive the cleaning segment 232 to rotate up and down around the rotating member 233.

[0042] In practical applications, to facilitate the sliding of the end of the support leg segment 231 away from the cleaning segment 232 within the spiral groove 251, a slider 234 can be provided at the end of the support leg segment 231 away from the cleaning segment 232, so that the support leg segment 231 is slidably connected to the spiral groove 251 via the slider 234. The slider 234 can be constructed as a near-circular structure. The number of spiral grooves 251 is the same as the number of cleaning components 230, and can be one, two, or three, etc. When there are multiple spiral grooves 251, the multiple spiral grooves 251 can be spaced apart around the axis of the rotating body 250.

[0043] Meanwhile, considering that the cleaning component 230 also needs to rotate for cleaning, that is, in addition to rotating relative to the support 220 to adjust the up and down movement of the cleaning section 232, the rotating body 250 can also rotate synchronously with the support 220 to satisfy the self-rotation cleaning function of the cleaning component 230.

[0044] Therefore, such as Figure 3 and Figure 4 As shown, in one feasible embodiment, the side brush assembly may further include a one-way rotating member 240, which has an outer ring fixedly connected to the bracket 210 and an inner ring that can rotate unidirectionally relative to the outer ring in a second direction, the inner ring being connected to the rotating body 250.

[0045] Thus, when the drive assembly 300 drives the carrier 220 to rotate in the first direction, the one-way rotating member 240 blocks the rotation of the rotating body 250. At this time, the carrier 220 can rotate relative to the rotating body 250. The carrier 220 drives the cleaning member 230 to rotate and causes the slider 234 to slide towards the bottom end of the spiral groove 251, causing the other end of the support leg section 231 to flip upward, thereby causing the cleaning section 232 to move upward. When the slider 234 slides to the bottom end of the spiral groove 251, the carrier 220 can no longer rotate relative to the rotating body 250. At the same time, due to the obstruction of the one-way rotating member 240, the final form is that the cleaning section 232 flips upward, and the side brush stops rotating.

[0046] When the drive assembly 300 drives the carrier 220 to rotate in a second direction opposite to the first direction, the slider 234 can first slide towards the top of the spiral groove 251, causing the cleaning section 232 to flip downwards and contact the ground. When the slider 234 slides to the top of the spiral groove 251, it drives the rotating body 250 to rotate synchronously with the carrier 220. Alternatively, when the drive assembly 300 drives the carrier 220 to rotate in the second direction, the slider 234 slides towards the top of the spiral groove 251, causing the cleaning section 232 to flip downwards and contact the ground, while simultaneously driving the rotating body 250 to rotate in the second direction. However, due to the friction of the rotating body 250 itself, its rotational speed is slightly less than that of the carrier 220, allowing the slider 234 to slide towards the top of the spiral groove 251. When the slider 234 slides to the top of the spiral groove 251, it drives the rotating body 250 to rotate synchronously with the carrier 220.

[0047] In practical applications, the one-way rotating component 240 can be a one-way bearing. For the specific structure of the one-way bearing, please refer to the existing technology.

[0048] It should be noted that the unidirectional rotation direction of the unidirectional rotating component 240 should correspond to the direction of the spiral groove 251. Specifically, as shown in... Figure 3 and Figure 4 As shown in the example, the spiral groove 251 is a right-hand spiral structure, and the second direction mentioned above should be counterclockwise. In this way, when the drive assembly 300 drives the support seat 220 to rotate in the first direction (clockwise), the one-way rotating member 240 blocks the rotation of the rotating body 250, so that the support seat 220 can rotate relative to the rotating body 250, and the slider 234 can slide towards the bottom end of the spiral groove 251, causing the other end of the support leg section 231 to flip upward, thereby causing the cleaning section 232 to move upward.

[0049] Of course, the above functions can also be achieved by replacing the one-way rotating part 240 with a disconnection mechanism. Specifically, the disconnection mechanism disconnects the rotating body 250 from the support 210, allowing the bearing seat 220 and the rotating body 250 to rotate synchronously. The disconnection mechanism also connects the rotating body 250 to the support 210, allowing the bearing seat 220 and the rotating body 250 to move relative to each other, thereby adjusting the up-and-down sliding of the cleaning section 232. The disconnection mechanism can refer to existing clutch structures and will not be described in detail here.

[0050] Considering that the structure of the one-way rotating component 240 is more compact and simple, this application preferably uses the one-way rotating component 240 to assist in realizing the synchronous rotation and relative rotation of the rotating body 250 and the bearing seat 220, which will be described in the following description.

[0051] The aforementioned rotating body 250 can be directly connected to the inner ring of the unidirectional rotating component 240.

[0052] The aforementioned rotating body 250 can also be connected to the inner ring of the one-way rotating component 240 via a mating sleeve 260. Specifically, as shown... Figure 4 and Figure 6 As shown, the outer wall surface of the mating sleeve 260 can be connected to the inner ring of the one-way rotating member 240, and the inner wall surface of the mating sleeve 260 mates with the upper outer wall surface of the rotating body 250.

[0053] In practical applications, the outer wall surface of the mating sleeve 260 can be interference-fitted or glued to the inner ring of the unidirectional rotating component 240. The upper outer wall surface of the rotating body 250 has an external hexagonal surface, and the spiral groove 251 is formed on the lower outer wall surface of the rotating body 250. Correspondingly, the inner wall surface of the mating sleeve 260 has an internal hexagonal surface. When the upper part of the rotating body 250 is inserted into the interior of the mating sleeve 260, the external hexagonal surface and the internal hexagonal surface engage, thereby the unidirectional rotating component 240 can restrict the unidirectional rotation of the rotating body 250.

[0054] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the housing may include a housing 222. The housing 222 may have a side extension 2221 and an outer extension 2222, wherein the side extension 2221 extends radially outward from the bottom periphery of the transmission member 221, and the outer extension 2222 extends upward from the periphery of the side extension 2221. A clearance hole 2223 is provided on the side of the outer extension 2222, allowing for the installation of a bracket on the housing. The rotating member 233 can be connected to the bracket, and the end of the support leg 231 away from the cleaning section 232 extends through the clearance hole 2223 into the spiral groove 251. When the end of the support leg 231 adjacent to the transmission member 221 moves to the top of the spiral groove 251, the cleaning section 232 is at least partially located below the side extension 2221. In this way, the side extension 2221 and the outer extension 2222 can block external dirt, reduce the possibility of external dirt entering the rotating body 250 and the support 210, and prevent dirt from accumulating and affecting the normal rotation of the rotating body 250, the support leg section 231 and the transmission component 221.

[0055] Furthermore, the side brush assembly 200 may also include a top cover 270, which is connected to the top end of the extension 2222 to close the top opening of the housing 222, preventing external dirt from entering the rotating body 250 and the support 210 through the top opening of the housing 222. Simultaneously, the top cover 270 is also provided with a through hole 271, through which the rotating body 250 passes and partially extends into the area formed by the transmission member 221, the housing 222, and the top cover 270, and the spiral groove 251 is located within the area formed by the transmission member 221, the housing 222, and the top cover 270.

[0056] In practical applications, the junction between the top cover 270 and the housing 222 can also be provided with clearance holes 2223. The clearance holes 2223 of the top cover 270 and the clearance holes 2223 of the housing 222 are spliced ​​together to form a hole for the cleaning component 230 to pass through. Of course, clearance holes 2223 can also be provided only on the top cover 270, and the cleaning component 230 is connected to the top cover 270 through the rotating component 233.

[0057] To prevent the upper part of the rotating body 250 from detaching from the interior of the mating sleeve 260, in one feasible embodiment, the bottom end of the rotating body 250 abuts against the housing 222, thereby supporting the rotating body 250 and keeping the upper part of the rotating body 250 inside the mating sleeve 260. Furthermore, the point contact and / or line contact between the rotating body 250 and the housing 222 reduces the friction between them, preventing excessive force transmitted to the unidirectional rotating member 240 when the rotating body 250 rotates relative to the support 220, which could damage the unidirectional rotating member 240. Simultaneously, the bottom end of the rotating body 250 abuts against the housing 222, allowing the support 220 to utilize this friction to transmit power and drive the rotating body 250 to rotate when the rotating body 250 and the support 220 rotate synchronously.

[0058] Regarding the specific structure of driver component 300, as follows: Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in one feasible embodiment, the drive assembly 300 may include a power source 310 and a transmission gear 320, wherein the power source 310 is connected to the transmission member 221 via the transmission gear 320, thereby driving the transmission member 221 to rotate. The bottom end of the transmission gear 320 abuts against the mating sleeve 260, thereby the mating sleeve 260 can also support and limit the transmission gear 320.

[0059] Optionally, the transmission gear 320 and the mating sleeve 260 are in point or line contact to reduce the friction between the rotating body 250 and the housing 222, thus preventing excessive force transmitted to the unidirectional rotating component 240 when the rotating body 250 rotates relative to the bearing seat 220, which could damage the unidirectional rotating component 240. Simultaneously, the bottom end of the transmission gear 320 abuts against the mating sleeve 260, allowing the bearing seat 220 to utilize this friction to transmit power and drive the rotating body 250 to rotate when the rotating body 250 and the bearing seat 220 rotate synchronously.

[0060] In practical applications, the power source 310 can be an electric motor, which can then drive the transmission component 221 to rotate via the transmission gear 320 by utilizing the motor's forward and reverse rotation function.

[0061] In one feasible implementation, the aforementioned transmission gear 320 can be directly connected to the transmission member 221.

[0062] In another alternative embodiment, the transmission member 221 is provided with an upward-opening mounting groove 2211. The drive assembly 300 also includes a drive rod 330, which is connected to the transmission gear 320 and inserted into the mounting groove 2211. A fastener 400 passes through the bottom of the transmission member 221 from below and is connected to the drive rod 330.

[0063] In practical applications, the drive rod 330 and the transmission gear 320 can be integrally formed. The cross-section of the mounting groove 2211 matches the cross-section of the drive rod 330, and the cross-sectional shape of both is non-circular, such as quadrilateral, pentagon or hexagon, thereby preventing relative rotation between the drive rod 330 and the transmission component 221.

[0064] like Figure 7 As shown, in one feasible embodiment, the power source 310 can be connected to the transmission gear 320 via the transmission assembly 340, thereby achieving deceleration and staggered arrangement using the transmission assembly 340 and the transmission gear 320. Accordingly, the bracket 210 can be constructed as a gearbox structure with a receiving cavity 211, in which the transmission assembly 340, the one-way rotating member 240, the mating sleeve 260, and the transmission gear 320 are disposed.

[0065] In practical applications, the bracket 210 can be composed of an upper shell and a lower shell. The transmission component 340, the bearing seat 220, the rotating body 250, the one-way rotating part 240 and the mating sleeve 260 are installed on the lower shell. When the upper shell and the lower shell are connected, the upper shell and the mating sleeve 260 together realize the vertical limit of the transmission gear 320.

[0066] Based on the same concept, such as Figure 8 As shown, this application also provides a side brush assembly that can be integrally installed on or detached from a cleaning device. Specifically, the side brush assembly may include a transmission component 221, a housing, a rotating body 250, and a cleaning component 230. The housing is connected to the transmission component 221, and the housing rotating body 250 is sleeved on the transmission component 221. The outer circumferential surface of the rotating body 250 is provided with a helical mechanism. The cleaning component 230 has a leg section 231 and a cleaning section 232. The leg section 231 is connected to the housing via a rotating component 233. One end of the leg section 231 is connected to the cleaning section 232, and the other end of the leg section 231 can slide along the helical mechanism.

[0067] Furthermore, the side brush assembly also includes a bracket 210 and a one-way rotating member 240. The one-way rotating member 240 has an outer ring fixedly connected to the bracket 210 and an inner ring that can rotate unidirectionally relative to the outer ring in a second direction. The rotating body 250 is connected to the inner ring, and the helical mechanism is configured as a helical groove 251 located on the outer wall of the rotating body 250, the helical groove 251 surrounding the axis of the rotating body 250. The end of the support leg segment 231 away from the cleaning section 232 remains within the helical groove 251. Along the axial direction of the rotating body 250, the rotating member 233 is located on the housing. When the transmission member 221 drives the housing to rotate in the second direction, the housing rotates relative to the rotating body 250, and the other end of the support leg segment 231 slides towards the bottom end of the helical groove 251, causing one end of the support leg segment 231 to flip upwards, thereby moving the cleaning section 232 upwards.

[0068] It should be noted that the specific structures of the transmission component 221, housing, rotating body, and cleaning component 230 can be found in the detailed descriptions in the above embodiments, and will not be repeated here.

[0069] The terms "upper" and "lower" are used to describe the relative positions of the various structures in the accompanying drawings.
