Description

Technical Field

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

[0002] With the continuous development of technology, cleaning equipment such as robotic vacuum cleaners are becoming increasingly popular. Taking robotic vacuum cleaners as an example, when a robotic vacuum cleaner is working, the roller brush assembly installed on the body rotates, and the garbage on the ground is thrown into the suction port by the rotating roller brush assembly. In this way, the garbage can be more effectively sucked into the internal dustbin of the robotic vacuum cleaner to achieve the purpose of cleaning.

[0003] However, in related technologies, when the roller brush assembly rotates, it is easy to get hair and other debris that can easily become tangled. This can cause the robot vacuum to get stuck in hair or other debris, thus affecting the normal cleaning operation. This not only damages the roller brush assembly of the robot vacuum, but also makes the roller brush assembly difficult to clean. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] With the continuous development of technology, cleaning equipment such as robotic vacuum cleaners are becoming increasingly popular. Taking robotic vacuum cleaners as an example, when a robotic vacuum cleaner is working, the roller brush assembly mounted on its body rotates. Debris on the ground is thrown into the suction port by the rotating roller brush assembly, allowing it to be more effectively sucked into the internal dustbin for cleaning. However, in related technologies, the roller brush assembly easily gets tangled with hair and other debris during rotation, causing the robotic vacuum cleaner to become prone to hair tangling and jamming, thus affecting the normal cleaning operation. This not only damages the roller brush assembly but also makes it difficult to clean.

[0036] Based on the above considerations, in order to solve the problem in related technologies where hair easily gets tangled in the roller brush assembly during rolling cleaning, leading to difficulty in cleaning or even damage to the roller brush assembly, a cleaning device has been designed. At least part of the roller brush assembly of the cleaning device is located at the suction port. The roller brush assembly forms a cleaning area by rolling, and the dust and debris gathered during cleaning can be sucked into the collection box through the suction port. When hair gets tangled in the roller brush assembly during rolling cleaning, the cleaning area formed by the rolling hook structure will also sweep over the hook structure, so that the hook structure can hook the hair tangled in the roller brush assembly and suck it into the collection box through the suction port. This can effectively reduce the probability of hair getting tangled in the roller brush assembly, thereby effectively reducing the probability of material jamming and damage to the cleaning device, and the cleaning effect of the cleaning device is better.

[0037] For ease of description, we will take a robotic vacuum cleaner as an example to explain the cleaning equipment provided in this application in detail.

[0038] Please refer to Figures 1 to 6 This application provides a cleaning device 1000, including a device body 100, a roller brush assembly 200, and a hook structure 300. A collection box (not shown in the figure) is formed inside the device body 100. A suction port 101 is provided on the device body 100 and is connected to the collection box. The suction port 101 is configured to generate negative pressure. The roller brush assembly 200 is rotatably disposed on the device body 100, and at least a portion of the roller brush assembly 200 is located at the suction port 101. The roller brush assembly 200 is configured to roll and form a cleaning area. The hook structure 300 is disposed on the device body 100 and located around the suction port 101. The hook structure 300 is located within the cleaning area.

[0039] Among them, the main body 100 refers to the main structure of the cleaning equipment 1000, that is, the main parts including the shell structure and internal control structure of the cleaning equipment 1000.

[0040] A collection box is formed inside the main body 100 of the equipment; the collection box is used to collect dust, hair and other dirt sucked in from the suction port 101. Optionally, the collection box can be detachably installed inside the main body 100 of the equipment, so that the collection box can be removed and cleaned, thereby improving the convenience of cleaning the collection box.

[0041] The main body 100 of the device is provided with a suction port 101; optionally, the suction port 101 can be located at any point on the bottom of the main body 100; for example, the suction port 101 can be located at the center of the bottom of the main body 100, or the suction port 101 can be located off-center from the bottom center of the main body 100. The suction port 101 is connected to the collection box, and a negative pressure can be formed at the suction port 101; thereby, the suction port 101 can use the formed negative pressure to suck in hair, dust and other garbage, so as to achieve the purpose of cleaning and dust collection.

[0042] It should be understood that the negative pressure at the suction port 101 can be, but is not limited to, negative pressure created by the suction of a fan device.

[0043] The roller brush assembly 200 refers to the structural component used to achieve cleaning.

[0044] The roller brush assembly 200 is rotatably mounted on the main body 100 of the device. The roller brush assembly 200 can rotate around its own axial direction and performs a cleaning operation on the target object (such as the floor, carpet, etc.) during the rotation. It can be understood that the area swept by the roller brush assembly 200 during the rotation is the cleaning area.

[0045] At least a portion of the roller brush assembly 200 is located at the suction port 101; thus, during the rolling cleaning process, the hair, dust and other debris gathered by the roller brush assembly 200 can be sucked into the collection box by the suction port 101.

[0046] Hook structure 300 refers to a structural component whose end section forms a hook shape.

[0047] The hook structure 300 is disposed on the main body 100 of the equipment and located around the suction port 101; the number of hook structures 300 can be one or more. Optionally, the hook structure 300 can be fixed to the main body 100 by means of welding, bonding, snap-fit ​​connection, fastener connection, etc.

[0048] The hook structure 300 can be arranged around the periphery of the suction port 101; or, the hook structure 300 can be arranged sequentially along the axial direction of the roller brush assembly 200 and placed on one side of the suction port 101.

[0049] The hook structure 300 is located within the cleaning area. Thus, when the roller brush assembly 200 rolls to perform cleaning, if hair gets tangled in it, the hair will roll synchronously with the roller brush assembly 200 within the cleaning area. When the hair rolls to the hook structure 300, the roller brush assembly 200 continues to roll, and the hair is easily hooked by the hook structure 300. This allows the roller brush assembly 200 to separate from the hair, enabling the suction port 101 to draw the separated hair into the collection box.

[0050] The cleaning device 1000 provided in this application embodiment has at least a portion of the roller brush assembly 200 located at the suction port 101. The roller brush assembly 200 rolls to form a cleaning area for cleaning operations. The dust and debris collected during cleaning can be sucked into the collection box through the suction port 101. When hair gets tangled in the roller brush assembly 200 during the rolling cleaning process, the cleaning area formed by the rolling hook structure 300 will also sweep over the hook structure 300. Thus, the hook structure 300 can hook the hair tangled in the roller brush assembly 200 and suck it into the collection box through the suction port 101. This can effectively reduce the probability of hair getting tangled in the roller brush assembly 200, thereby effectively reducing the probability of the cleaning device 1000 getting stuck and damaged, and the cleaning effect of the cleaning device 1000 is better.

[0051] Please refer to Figures 1 to 6 In some embodiments, a cleaning chamber 110 is provided at the bottom of the device body 100, at least a portion of the roller brush assembly 200 is disposed in the cleaning chamber 110, and the two opposite ends of the roller brush assembly 200 are rotatably connected to the inner side of the cleaning chamber 110 along the axial direction X; the dust suction port 101 is opened on the inner side of the cleaning chamber 110, and the hook structure 300 is disposed on the inner side of the cleaning chamber 110.

[0052] The cleaning chamber 110 is used to accommodate and assemble the roller brush assembly 200. In some embodiments, the cleaning chamber 110 may be a cylindrical cavity.

[0053] The upper part of the roller brush assembly 200 can be disposed inside the cleaning chamber 110, and the two opposite ends of the roller brush assembly 200 along the axial direction X are rotatably connected to the inner side of the cleaning chamber 110; thus, when the roller brush assembly 200 rotates, the cleaning area formed by the roller brush assembly 200 can perform cleaning operations at the bottom of the equipment body 100; and the dust suction port 101 opened on the inner side of the cleaning chamber 110 can suck up the garbage collected at the roller brush assembly 200.

[0054] In this embodiment, the hook structure 300 is disposed on the inner side of the cleaning chamber 110. When the roller brush assembly 200 rolls and wraps around hair, the roller brush assembly 200 carries the wrapped hair as it rolls and sweeps across the inner side of the cleaning chamber 110. In this way, the hook structure 300 can hook the hair, so that the hair can be separated from the continuously rolling roller brush assembly 200. Furthermore, the suction port 101 provided on the inner side of the cleaning chamber 110 can more easily suck up the hair on the hook structure 300 located on the inner side of the cleaning chamber 110.

[0055] Please refer to Figures 1 to 6In some embodiments, the suction port 101 is located in the middle of the inner side of the cleaning chamber 110 along the axial direction X of the roller brush assembly 200; and multiple hook structures 300 are provided on both sides of the inner side of the cleaning chamber 110 along the axial direction X of the roller brush assembly 200, opposite to the suction port 101.

[0056] In this embodiment, the suction port 101 is located at the center of the inner side of the cleaning chamber 110 along the axial direction X of the roller brush assembly 200. This allows the suction port 101 to achieve a more balanced adsorption effect on debris on both sides of the roller brush assembly 200 along the axial direction X.

[0057] Meanwhile, in this embodiment, multiple hook structures 300 are provided on both sides of the inner surface of the cleaning chamber 110, opposite to each other along the axial direction X of the suction port 101 of the roller brush assembly 200. Thus, during the rolling process of the roller brush assembly 200, the hook structures 300 can hook hair onto the roller brush assembly 200 located on opposite sides along the axial direction X of the suction port 101. After the hair is hooked by the hook structures 300 and separated from the roller brush assembly 200, the hair can be more easily sucked into the central suction port 101; this effectively improves the cleaning effect.

[0058] Please refer to Figures 1 to 6 In some embodiments, multiple hook structures 300 are symmetrically distributed about the suction port 101 along the axial direction X of the roller brush assembly 200; multiple hook structures 300 located on either side of the suction port 101 are arranged sequentially along the direction intersecting the axial direction X of the roller brush assembly 200.

[0059] Multiple hook structures 300 are symmetrically distributed along the axial direction X of the roller brush assembly 200; thus, the hook structures 300 on both sides of the suction port 101 along the axial direction X have a roughly the same effect on hooking hair onto the roller brush assembly 200. This ensures the effective separation of tangled hair from the entire roller brush assembly 200.

[0060] In this arrangement, multiple hook structures 300 on any one side are sequentially arranged along the axial direction X intersecting the roller brush assembly 200. Thus, as the multiple hook structures 300 are sequentially distributed along the axial direction X of the roller brush assembly 200, they also shift along the direction intersecting the axial direction X. Furthermore, along the axial direction X of the roller brush assembly 200, the two rows of hook structures 300 located on opposite sides of the suction port 101 can form a "V" shape.

[0061] Please refer to Figures 1 to 6 In some embodiments, the cleaning device 1000 further includes a drive structure (not shown in the figure), which is disposed within the device body 100 and whose output end is connected to the roller brush assembly 200.

[0062] The drive structure may be, but is not limited to, a drive motor; the drive motor is used to drive the roller brush assembly 200 to rotate in order to achieve the purpose of automatic cleaning.

[0063] Please refer to Figures 1 to 6 In some embodiments, the roller brush assembly 200 includes a main body 210 and a bristle structure 220 and an adhesive strip structure 230 disposed on the main body 210; the main body 210 is rotatably connected to the inner side of the cleaning chamber 110; the bristle structure 220 is arranged in a ring around the surface of the main body 210 in a direction intersecting the axial direction X of the roller brush assembly 200; the adhesive strip structure 230 is spaced apart from the bristle structure 220; wherein the bristle structure 220 and the adhesive strip structure 230 rotate around the axial direction X of the roller brush assembly 200 and form a cleaning area.

[0064] Understandably, the main body 210 refers to the main body 210 of the roller brush assembly 200 used to support the bristle structure 220 and the rubber strip structure 230. The main body 210 is rotatably connected to the inner side of the cleaning chamber 110; the main body 210 can be rotated by a drive structure to achieve synchronous rotation of the bristle structure 220 and the rubber strip structure 230 for cleaning.

[0065] The tufted structure 220 refers to multiple tufts of hair fixedly arranged on the main body 210. The multiple tufts of hair form the tufted structure 220 and can roll to achieve cleaning operations.

[0066] The adhesive strip structure 230 refers to a strip-shaped hard adhesive structure fixedly mounted on the main body 210. The adhesive strip structure 230 provides support, reducing the probability that hair will directly wrap around and become trapped on the main body 210 when the roller brush assembly 200 is wrapping hair. The adhesive strip structure 230 and the hair-embedding structure 220 are spaced apart, allowing multiple adhesive strips to support the wrapped hair. This facilitates the subsequent operation of the hook structure 300 to hook the hair.

[0067] The bristle structure 220 is arranged in a ring around the surface of the main body 210 along the axial direction X intersecting the roller brush assembly 200; thus, when the main body 210 rolls, the bristle structure 220 at different positions has different contact time with the target object, thereby playing the role of sweeping and collecting the garbage so that it can be sucked up by the suction port 101.

[0068] Please refer to Figures 1 to 6 In some embodiments, there are multiple adhesive strip structures 230, and multiple adhesive strip structures 230 are arranged sequentially and spaced apart on the surface of the main body 210 around the axial direction X of the roller brush assembly 200; a bristle structure 220 is provided between any two adjacent adhesive strip structures 230.

[0069] In this embodiment, the number of adhesive strip structures 230 is set to multiple; for example, the adhesive strip structures 230 can be any number of two, three, or more. Multiple adhesive strip structures 230 are sequentially spaced on the surface of the main body 210 around the axial direction X of the roller brush assembly 200. Thus, in the axial direction X of the roller brush assembly 200, multiple adhesive strip structures 230 are sequentially spaced; when the roller brush assembly 200 is washing, if hair initially gets entangled, the multiple adhesive strip structures 230 can work together to support the initially entangled hair, reducing the amount of hair entangled onto the main body 210. This facilitates the subsequent hair removal operation by the hook structure 300.

[0070] A bristle-embedded structure 220 is provided between any two adjacent rubber strip structures 230; thus, the bristle-embedded structure 220 can perform cleaning and brushing operations on the target object, and the rubber strip structure 230 can perform support operations simultaneously.

[0071] Please refer to Figures 1 to 6 In some embodiments, the adhesive strip structure 230 includes a first adhesive strip portion 231 and a second adhesive strip portion 232 connected and integrally formed. The first adhesive strip portion 231 and the second adhesive strip portion 232 are respectively arranged around the surface of the main body portion 210 in a direction intersecting the axial direction X of the roller brush assembly 200. In the axial direction X of the roller brush assembly 200, the first adhesive strip portion 231 and the second adhesive strip portion 232 are symmetrically arranged about the center of the main body portion 210.

[0072] It should be understood that the first rubber strip portion 231 and the second rubber strip portion 232 respectively refer to two sections of the same rubber strip structure 230 along the axial direction X of the roller brush assembly 200.

[0073] The first adhesive strip 231 and the second adhesive strip 232 are respectively arranged in a ring around the surface of the main body 210 along a direction intersecting the axial direction X of the roller brush assembly 200; and the first adhesive strip 231 and the second adhesive strip 232 are symmetrically arranged about the center of the main body 210 along the axial direction X of the roller brush assembly 200. In this way, the first adhesive strip 231 and the second adhesive strip 232 are symmetrically distributed on the main body 210 and can be combined to form a "V" shaped structure.

[0074] With this configuration, the adhesive strip structure 230, through the distribution of the first adhesive strip portion 231 and the second adhesive strip portion 232 on the main body portion 210, and in conjunction with the rotation direction of the roller brush assembly 200, enables the adhesive strip structure 230 to gather the hair towards the center portion of the main body portion 210 along the axial direction X when supporting the hair, so as to facilitate the hair removal operation of the hook structure 300.

[0075] Please refer to Figures 1 to 6In some embodiments, the bristle implantation structure 220 includes a first bristle implantation portion 221 and a second bristle implantation portion 222, which are respectively arranged in a ring around the surface of the main body portion 210 along a direction intersecting the axial direction X of the roller brush assembly 200; the first bristle implantation portion 221 and the second bristle implantation portion 222 are symmetrically arranged about the center of the main body portion 210 along the axial direction X of the roller brush assembly 200.

[0076] It should be understood that the first bristle implantation section 221 and the second bristle implantation section 222 refer to two segments of the same bristle implantation structure 220 along the axial direction X of the roller brush assembly 200.

[0077] The first bristle-planting portion 221 and the second bristle-planting portion 222 are respectively arranged in a ring around the surface of the main body portion 210 along the axial direction X intersecting the roller brush assembly 200; and the first bristle-planting portion 221 and the second bristle-planting portion 222 are symmetrically arranged about the center of the main body portion 210 along the axial direction X of the roller brush assembly 200. In this way, the first bristle-planting portion 221 and the second bristle-planting portion 222 are symmetrically distributed on the main body portion 210 and can be combined to form a "V" shaped structure.

[0078] With this configuration, the bristle structure 220, through the distribution of the first bristle section 221 and the second bristle section 222 on the main body 210, and in conjunction with the rotation direction of the roller brush assembly 200, enables the bristle structure 220 to gather the garbage in the middle during the rolling cleaning process, so as to facilitate the gathering of garbage and the suction operation of the dust inlet 101.

[0079] Please refer to Figures 1 to 6 In some embodiments, along the rotation direction of the roller brush assembly 200, one of the plurality of hook structures 300 closer to the suction port 101 is located in front of another hook structure 300 further away from the suction port 101.

[0080] The term "near or far from the suction port 101" refers to a comparison of the distances between the centers of two adjacent hook structures 300 and the suction port 101 along the axial direction X of the roller brush assembly 200. If the distance between the hook structure 300 and the center of the suction port 101 along the axial direction X of the roller brush assembly 200 is shorter, then the hook structure 300 is closer to the suction port 101; otherwise, it is farther away from the suction port 101.

[0081] With this configuration, when the roller brush assembly 200 rotates to clean, the hook structure 300 near the suction port 101 can first contact the hair pre-wound on the adhesive strip structure 230, so that the hair can be preferentially hooked off by the hook structure 300 near the suction port 101; and after the hook structure 300 hooks the hair off the rotating roller brush assembly 200, the suction port 101 can more easily suck up the hair on the hook structure 300 near the suction port 101; thus, the hair removal operation can be effectively improved.

[0082] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
