[0002] Cleaning equipment refers to mechanical devices used for cleaning various places and items. Taking a robotic vacuum cleaner as an example, hair may become entangled in the brush during the cleaning process. To ensure cleaning effectiveness, relevant technologies incorporate a cutting mechanism within the robotic vacuum cleaner. This mechanism uses blades to cut the hair tangled in the brush, facilitating its timely removal. However, the driving mechanism of this cutting mechanism is relatively complex. Utility Model Content

[0003] The main purpose of this invention is to provide a transmission component, a cutting mechanism, a cleaning module, and a cleaning device, aiming to solve the problem of the complex driving method of the cutting mechanism in related technologies.

The cleaning module includes a roller and an end cap disposed at one end of the roller. The roller can rotate relative to the end cap around its central axis. The transmission assembly includes:

[0005] The transmission body includes a first transmission part and a mating part. The first transmission part is disposed on the drum and can rotate synchronously with the drum. The mating part is housed inside the drum and fixed to the end cap.

[0015] Preferably, the second transmission unit includes an eccentric structure disposed in the first transmission unit. The rotation axis of the eccentric structure is collinear with the central axis of the first transmission unit and rotates coaxially with the first transmission unit. During the rotation of the eccentric structure, the contact position between the far center point of the eccentric structure in its radial direction and the cutting assembly changes periodically in the axial direction of the drum, so as to drive the cutting assembly to perform reciprocating linear motion along the axial direction of the drum.

[0016] In this structure, the connecting part is formed at a local position near the center of rotation of the eccentric structure, and the transition part is formed at the far center of the eccentric structure.

[0017] Preferably, the second transmission unit includes a crank, a connecting rod, and a slider. One end of the crank can rotate coaxially with the first transmission unit, and both ends of the connecting rod are respectively hinged to the other end of the crank and the slider. The slider is connected to the cutting assembly via transmission.

[0018] The connecting part includes a crank, and the conversion part includes a connecting rod and a slider.

[0019] This utility model also proposes a cutting mechanism, which is disposed on the roller of the cleaning module, including:

[0020] The cutting assembly includes a movable blade movably mounted on a drum and a fixed blade fixedly mounted on the drum, both extending axially along the drum and facing each other; and,

[0021] The aforementioned transmission assembly has a second transmission part that is connected to the moving blade to drive the moving blade to reciprocate relative to the fixed blade in the axial direction of the drum.

[0029] Preferably, the blade holder has a notch on the side opposite to the cutting edge of the moving blade, and the notch has opposing first and second inner walls in the axial direction of the roller;

[0030] The eccentric structure is housed within the notch, and during its rotation, the centroid of the eccentric structure alternately contacts the first inner wall and the second inner wall.

[0037] This utility model also proposes a cleaning device, including the above-mentioned cleaning module.

[0038] The technical solution provided by this utility model has at least the following advantages:

[0039] The transmission assembly provided by this utility model includes a transmission body and a second transmission part. The transmission body includes a first transmission part that can rotate synchronously with the drum and a mating part fixed to the end cover. The mating part is connected to the first transmission part and can drive the first transmission part to rotate around its own central axis when the first transmission part rotates synchronously with the drum. The second transmission part is connected to the first transmission part and the cutting assembly of the cutting mechanism, so that when the first transmission part rotates, it can drive the cutting assembly to perform reciprocating linear motion along the axial direction of the drum. That is, through the first transmission part and the mating part, the rotation of the drum is converted into the rotation of the first transmission part, and at the same time, through the second transmission part, the rotation of the first transmission part is converted into driving the cutting assembly to perform reciprocating linear motion; thus, the rotation of the drum can be converted into the linear motion of the cutting assembly using only three components connected by transmission, and the transmission structure is simple.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] Cleaning equipment refers to mechanical equipment used for cleaning various places and items. Cleaning equipment can be vertical or horizontal, handheld or self-propelled, wireless or wired; no specific limitations are made here. Similarly, this utility model does not specifically limit the cleaning function of the cleaning equipment; it can be used for sweeping, vacuuming, mopping, wiping glass, cleaning carpets, etc.

[0056] Taking robotic vacuum cleaners as an example, their cleaning modules typically feature roller brushes. These brushes rotate at high speed, creating friction with the floor to loosen and gather dirt. Combined with a suction system, this efficiently collects dust, hair, and debris. However, during the cleaning process, hair can sometimes become entangled in the roller brush.

[0057] In order to effectively clean the hair tangled on the roller brush and simplify the structure for cleaning tangled hair, this utility model improves the hair cutting mechanism 100 of the cleaning module 1000. The transmission component 1 of the cutting mechanism 100 will be described below with reference to the accompanying drawings.

[0058] Please see Figures 1 to 8 The attached figures show specific embodiments of the transmission component 1 provided by this utility model applied to the cutting mechanism 100, the cleaning module 1000, and finally in the cleaning equipment.

[0059] The cleaning module 1000 includes a roller brush body 200, which includes a hollow roller 201 and two end caps 202 disposed at both ends of the roller 201. The roller 201 can rotate relative to the two end caps 202 around its central axis.

[0060] Please see Figures 1 to 4The transmission assembly 1 includes a transmission body 11 and a second transmission part 12. The transmission body 11 includes a first transmission part 111 and a mating part 112. The first transmission part 111 is disposed on the drum 201 and can rotate synchronously with the drum 201. The mating part 112 is housed inside the drum 201 and fixed to the end cover 202. The mating part 112 is drively connected to the first transmission part 111 so that when the first transmission part 111 rotates synchronously with the drum 201, it drives the first transmission part 111 to rotate around its own central axis. The second transmission part 12 is drively connected to the first transmission part 111 and the cutting assembly 2 of the cutting mechanism 100 so that when the first transmission part 111 rotates, it drives the cutting assembly 2 to reciprocate linearly along the axial direction F1 of the drum 201.

[0061] It is understood that the transmission assembly 1 is generally used for power transmission between mechanical components, and therefore has power input and power output. In this invention, the transmission assembly 1 includes a transmission body 11 and a second transmission part 12. The transmission body 11 realizes power input through an external power source, while the second transmission part 12 serves as the power output.

[0062] To simplify the drive mechanism, the transmission component 1 is installed inside the roller 201 of the cleaning module 1000. When the roller 201 rotates around its central axis relative to the end cover 202, the first transmission part 111 installed on the roller 201 can rotate synchronously with the roller 201, thereby serving as the power input of the transmission body 11 and converting the rotation of the roller 201 into the power source of the transmission body 11.

[0063] At this time, the rotation of the roller 201 is converted into the power source of the first transmission part 111, causing the first transmission part 111 to rotate around the central axis of the roller 201. Since the fixed fitting part 112 is on the end cover 202, the first transmission part 111 can be regarded as rotating around the circumference of the fitting part 112. The fitting part 112 is connected to the first transmission part 111 in a transmission manner. After the power of the first transmission part 111 is transmitted to the fitting part 112, it is provided to the first transmission part 111 in the reverse direction, thereby driving the first transmission part 111 to rotate around its own central axis.

[0064] The second transmission unit 12 is connected to the first transmission unit 111 and the cutting component 2 of the cutting mechanism 100. Thus, when the first transmission unit 111 rotates, it drives the cutting component 2 to reciprocate linearly along the axial direction F1 of the roller 201. In other words, the rotation of the roller 201 is converted into the rotation of the first transmission unit 111 through the first transmission unit 111 and the mating part 112, while the second transmission unit 12 drives the cutting component 2 to reciprocate linearly. Therefore, the rotation of the roller 201 can be converted into the linear motion of the cutting component 2 using only three connected components, resulting in a simple transmission structure.

[0065] This invention does not impose specific limitations on the transmission method of the first transmission part 111 and the mating part 112. In one embodiment, please refer to... Figures 2 to 4 The mating part 112 extends along the axial direction F1 of the roller 201, and its outer periphery is provided with a first toothed part 113. The central axis of the first transmission part 111 intersects with the central axis of the mating part 112, and the outer periphery of the first transmission part 111 is provided with a second toothed part 114. The second toothed part 114 meshes with the first toothed part 113, so that the first transmission part 111 can rotate around its central axis while rotating synchronously with the roller 201.

[0066] In other words, the central axes of the first transmission part 111 and the mating part 112 are arranged intersecting. Since the mating part 112 is fixed to the end cover 202, when the first transmission part 111 rotates synchronously with the roller 201, it is equivalent to the first transmission part 111 rotating circumferentially around the mating part 112. At the same time, the first tooth 113 on the outer periphery of the mating part 112 and the second tooth 114 on the outer periphery of the first transmission part 111 mesh. At this time, the mating part 112 can output power in the opposite direction, driving the first transmission part 111 to rotate around its central axis.

[0067] This invention does not impose specific limitations on the structure of the first transmission part 111 and the mating part 112. Any structure that involves tooth meshing and can change the direction of the axis of rotation is acceptable.

[0068] In one embodiment, please refer to Figures 2 to 4 The mating part 112 includes a worm gear 115, which is arranged along the axial direction F1 of the roller 201 and has one end fixed to the end cover 202. The first transmission part 111 includes a worm wheel 116 rotatably mounted on the roller 201, and the teeth of the worm wheel 116 mesh with the teeth of the worm gear 115. Specifically, the first tooth 113 includes the teeth of the worm gear 115, and the second tooth 114 includes the teeth of the worm wheel 116.

[0069] A worm gear 115 is installed along the axial direction F1 of the drum 201, with one end of the worm gear 115 fixed to the end cover 202. Simultaneously, a worm wheel 116 is installed on the inner wall of the drum 201, and the worm wheel 116 can rotate along its central axis. When the worm wheel 116 rotates synchronously with the drum 201, it is equivalent to the worm wheel 116 rotating circumferentially around the worm gear 115. At the same time, the first tooth 113 of the worm gear 115 meshes with the second tooth 114 of the worm wheel 116. In this case, the worm gear 115 can output power in the opposite direction, driving the worm wheel 116 to rotate around its central axis.

[0070] To ensure the stability of the worm gear 115, in one embodiment, please refer to... Figure 2The transmission assembly 1 also includes a fixing structure, which includes a bearing 13 and a mounting base 14. The mounting base 14 is located on the inner wall of the roller 201, and a mounting groove 141 is formed on the mounting base 14. The bearing 13 is sleeved on the outer peripheral side of the worm 115 and is located near the first tooth 113. The bearing 13 is at least partially housed within the mounting groove 141. By providing the bearing 13 and the mounting base 14, the installation stability of the worm 115 can be improved.

[0071] In one embodiment, please refer to Figures 2 to 4 The central axis of the first transmission unit 111 is set at an angle to the central axis of the drum 201. The second transmission unit 12 includes a connecting part 121 and a conversion part 122. The connecting part 121 is connected to the first transmission unit 111 and can rotate synchronously. The conversion part 122 is connected to the connecting part 121 and the cutting assembly 2, so that when the connecting part 121 rotates, it drives the cutting assembly 2 to reciprocate linearly along the axial direction F1 of the drum 201.

[0072] This invention does not impose specific limitations on the structure of the second transmission unit 12. Anything that can convert rotation into reciprocating linear motion is acceptable.

[0073] In one embodiment, the second transmission unit 12 includes an eccentric structure 123 disposed on the first transmission unit 111. The rotation axis of the eccentric structure 123 is collinear with the central axis of the first transmission unit 111 and rotates coaxially with the first transmission unit 111.

[0074] During the rotation of the eccentric structure 123, the contact position between the distal point of the eccentric structure 123 in its radial direction and the cutting component 2 changes periodically in the axial direction F1 of the drum 201, thereby driving the cutting component 2 to reciprocate linearly along the axial direction F1 of the drum 201; wherein, a connecting part 121 is formed at a local position near the rotation center of the eccentric structure 123, and a conversion part 122 is formed at the distal point of the eccentric structure 123.

[0075] This invention does not impose specific limitations on the eccentric structure 123. To further simplify the structure of the transmission assembly 1, preferably, the eccentric structure 123 is configured as an eccentric wheel.

[0076] The following example uses "eccentric structure 123 configured as an eccentric wheel" to illustrate this concept. Figure 5 and Figure 6 The transmission path of transmission component 1 is described in detail.

[0077] The axis of rotation of the eccentric wheel is collinear with the central axis of the first transmission unit 111 and rotates coaxially with the first transmission unit 111. Please refer to... Figure 5Taking the orientation shown in the figure as an example, on the axis F1 of the roller 201, when the eccentric wheel rotates along its rotation axis and rotates until its centroid is on the right, the centroid of the eccentric wheel contacts the cutting component 2, thereby pushing the cutting component 2 to move to the right.

[0078] Please see Figure 6 Taking the orientation shown in the diagram as an example, on the axial direction F1 of the drum 201, when the eccentric wheel rotates along its rotation axis and rotates until its centroid is on the left, the centroid of the eccentric wheel contacts the cutting component 2, thereby pushing the cutting component 2 to move to the left. Thus, when the eccentric wheel rotates along its rotation axis, the centroid of the eccentric wheel alternately contacts the cutting component 2 on the left and right sides, thereby driving the cutting component 2 to perform reciprocating linear motion along the axial direction F1 of the drum 201.

[0079] In another embodiment, the second transmission unit 12 includes a crank, a connecting rod, and a slider. One end of the crank is coaxially rotatable with the first transmission unit 111, and both ends of the connecting rod are hinged to the other end of the crank and the slider, respectively. The slider is driven by the cutting assembly 2. The connecting part 121 includes a crank, and the conversion part 122 includes a connecting rod and a slider. That is, when the first transmission unit 111 rotates around its central axis, the rotation of the first transmission unit 111 is converted into linear motion of the slider through the connected crank, connecting rod, and slider, thereby driving the cutting assembly 2 to reciprocate linearly along the axial direction F1 of the roller 201.

[0080] Based on the above embodiments, this utility model also provides a cutting mechanism 100. Please refer to [link / reference]. Figure 4 , Figure 7 and Figure 8 The cutting mechanism 100 is disposed on the roller 201 of the cleaning module 1000. The cutting mechanism 100 includes a cutting assembly 2 and a transmission assembly 1. The cutting assembly 2 includes a movable blade 21 movably disposed on the roller 201 and a fixed blade 22 fixedly disposed on the roller 201. Both the movable blade 21 and the fixed blade 22 extend along the axial direction F1 of the roller 201 and are arranged facing each other. The second transmission part 12 of the transmission assembly 1 is connected to the movable blade 21 to drive the movable blade 21 to reciprocate relative to the fixed blade 22 along the axial direction F1 of the roller 201.

[0081] It should be noted that the transmission component 1 is configured as described above, which includes all the technical features of the transmission component 1. Therefore, the cutting mechanism 100 also includes all the technical features of the transmission component 1, and thus has the technical effects brought about by all the technical features described above.

[0082] The rotation of the roller 201 is converted into the rotation of the first transmission part 111 by the first transmission part 111 and the mating part 112 of the transmission assembly 1. At the same time, the rotation of the first transmission part 111 is converted into the movement of the moving blade 21 along the axial direction F1 of the roller 201 by the second transmission part 12 of the transmission assembly 1. The moving blade 21 drives the relative fixed blade 22 to reciprocate through the second transmission part 12, similar to the principle of an electric razor, to cut hair or other objects on the roller 201.

[0083] Both the moving blade 21 and the fixed blade 22 can be arranged in a serrated or wavy shape.

[0084] Specifically, please refer to Figure 7 The cutting assembly 2 also includes a blade holder 3 housed within the drum 201. The blade holder 3 is slidably mounted on the drum 201 along the axial direction F1. A movable blade 21 is disposed on the blade holder 3. A fixed blade 22 is located on the side of the movable blade 21 facing away from the blade holder 3. The second transmission unit 12 is connected to the blade holder 3 for transmission.

[0085] More specifically, the blade holder 3 is provided with two abutment parts 31, which are spaced apart on the axial direction F1 of the drum 201; the first transmission part 111 can rotate along its central axis, and the central axis of the first transmission part 111 is set at an angle to the central axis of the drum 201.

[0086] The second transmission unit 12 includes an eccentric structure 123 located between two abutting parts 31. The eccentric structure 123 can rotate synchronously with the first transmission unit 111, and during its rotation, the centroid of the eccentric structure 123 alternately contacts the two abutting parts 31.

[0087] During the synchronous rotation of the eccentric structure 123 with the first transmission part 111, the centroid of the eccentric structure 123 in its radial direction alternately contacts the two abutment parts 31, thereby driving the blade support 3 to drive the moving blade 21 to reciprocate linearly along the axial direction F1 of the roller 201.

[0088] In order to simplify the components of the cutting mechanism 100 and make the component arrangement of the cutting mechanism 100 more compact, please refer to one embodiment. Figure 4 and Figure 7 The blade holder 3 has a notch 32 on the side opposite to the cutting edge of the moving blade 21. The notch 32 has a first inner wall 321 and a second inner wall 322 opposite to each other in the axial direction F1 of the roller 201.

[0089] The eccentric structure 123 is housed within the notch 32, and during its rotation, the centroid of the eccentric structure 123 alternately contacts the first inner wall 321 and the second inner wall 322; wherein, the two abutting portions 31 include the first inner wall 321 and the second inner wall 322.

[0090] In other words, a notch 32 is provided on the blade holder 3, and the eccentric structure 123 is housed within the notch 32. During the synchronous rotation of the eccentric structure 123 with the first transmission part 111, the centroid of the eccentric structure 123 in its radial direction alternately contacts the first inner wall 321 and the second inner wall 322. This not only eliminates the need for an additional abutment part 31, but also makes the assembly of the eccentric structure 123 and the blade holder 3 more compact.

[0091] The following example uses "eccentric structure 123 configured as an eccentric wheel" to illustrate this concept. Figure 5 and Figure 6 The transmission path of transmission component 1 is described in detail.

[0092] The axis of rotation of the eccentric wheel is collinear with the central axis of the first transmission unit 111 and rotates coaxially with the first transmission unit 111. Please refer to... Figure 5 Taking the orientation shown in the figure as an example, on the axial direction F1 of the drum 201, when the eccentric wheel rotates along its rotation axis and rotates until its centroid is on the right, the centroid of the eccentric wheel contacts the first inner wall 321 of the notch 32, thereby pushing the blade support 3 to move to the right.

[0093] Please see Figure 6 Taking the orientation shown in the figure as an example, on the axial direction F1 of the drum 201, when the eccentric wheel rotates along its rotation axis and rotates until its centroid is on the left, the centroid of the eccentric wheel contacts the second inner wall 322 of the notch 32, thereby pushing the blade holder 3 to move to the left. Thus, when the eccentric wheel rotates along its rotation axis, the centroid of the eccentric wheel alternately contacts the first inner wall 321 and the second inner wall 322 on the left and right sides, thereby driving the blade holder 3 to perform reciprocating linear motion along the axial direction F1 of the drum 201.

[0094] This application does not impose a specific limit on the number of moving blades 21 and fixed blades 22, as long as the number of moving blades 21 and fixed blades 22 is the same and they correspond one-to-one.

[0095] Please see Figure 7 and Figure 8 In one embodiment, multiple movable blades 21 are provided, which are fixed on the blade support 3 and arranged side by side at intervals along the axial direction F1 of the roller 201. Multiple fixed blades 22 are provided, which are fixed on the inner wall of the roller 201 and arranged side by side at intervals along the axial direction F1 of the roller 201.

[0096] The cutting mechanism 100 also includes a pressure plate 4, which is located on the side of the blade holder 3 away from the moving blade 21 and is fixed to the inner wall of the roller 201. The pressure plate 4 presses against the blade holder 3 to press the moving blade 21 and the fixed blade 22 together.

[0097] Furthermore, a guide structure is provided between the pressure plate 4 and the blade holder 3, thereby guiding the movement of the blade holder 3 along the axial direction F1 of the roller 201.

[0098] This utility model also provides a cleaning module 1000. Please refer to [link / reference]. Figure 1 and Figure 2 The cleaning module 1000 includes a roller brush body 200, a cutting mechanism 100, and a drive assembly 300.

[0099] The roller brush body 200 includes a hollow roller 201 and two end caps 202 located at both ends of the roller 201. The roller 201 can rotate relative to the two end caps 202 around its central axis. The roller 201 is provided with an opening 203 that communicates with its interior.

[0100] When the cleaning module 1000 cleans the floor or carpet, the roller brush body 200 is very prone to getting tangled with hair or other filamentous materials. By providing a cutting mechanism 100 inside the roller 201, with the blades of its fixed blade 22 and moving blade 21 being adjacent and facing the opening 203, the hair on the roller brush body 200 is cut off, making the roller brush body 200 easy to clean.

Therefore, the cleaning module 1000 also includes all the technical features of the cutting mechanism 100, and thus has the technical effects brought about by all the technical features described above.

[0102] The rotation of the roller 201 is converted into the rotation of the first transmission part 111 by the first transmission part 111 and the mating part 112 of the transmission assembly 1. At the same time, the rotation of the first transmission part 111 is converted into the movement of the moving blade 21 along the axial direction F1 of the roller 201 by the second transmission part 12 of the transmission assembly 1. The moving blade 21 drives the relative fixed blade 22 to reciprocate through the second transmission part 12, similar to the principle of an electric razor, which can continuously and uninterruptedly cut hair and other filamentous materials on the roller brush body 200.

[0103] The drive assembly 300 includes a drive shaft 301 arranged along the axial direction F1 of the roller 201, which drives the roller 201. The mating part 112 of the cutting mechanism 100 and the drive shaft 301 are respectively disposed on two end caps 202, and the drive shaft 301 is rotatably mounted on the corresponding end cap 202 along the axial direction F1 of the roller 201.

[0104] Please see Figure 1 and Figure 2In one embodiment, the roller 201 includes a first cylindrical body and a second cylindrical body joined together to form an inner cavity for accommodating the cutting mechanism 100. Both ends of the first cylindrical body and the second cylindrical body are through-holes, resulting in the roller 201 having through-hole ends after the first and second cylindrical bodies are joined. Two end caps 202 are respectively disposed at both ends of the roller 201, and the roller 201 is rotatable relative to the two end caps 202 around its central axis.

[0105] This utility model also provides a cleaning device. The cleaning device can be a vacuum cleaner, a robotic vacuum cleaner, or a vacuum and mop combo, etc. The cleaning device includes the cleaning module 1000 in the above embodiments, and has all the technical features of the cleaning module 1000 and the technical effects brought about by all the technical features.

The cleaning body is equipped with a control circuit board or control switch to control the cleaning module 1000 to perform cleaning work. By providing a cutting mechanism 100 on the cleaning module 1000 of the cleaning equipment, the roller brush on the cleaning equipment is easier to clean, the cleaning effect is better, and the service life of the cleaning equipment can be extended.
