Description

Technical Field

[0001] This invention relates to the technical field of cleaning tools, and more specifically to a cleaning mechanism and cleaning equipment. Background Technology

[0002] When cleaning surfaces, especially those with a lot of hair like blankets, the cleaning mechanism of cleaning equipment can easily become entangled in hair or other filaments, making it difficult to clean thoroughly or even causing the brush to jam. The traditional solution is to incorporate a cutting blade into the cleaning mechanism to cut the hair and other filaments before sucking them into the cleaning equipment. However, this cutting action requires a separate cutting drive mechanism, making the cleaning mechanism complex and relatively expensive. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the transmission cutting tool needs to be equipped with a corresponding cutting drive mechanism, which makes the structure of the cleaning mechanism complex and the cost high.

[0007] A transmission assembly is disposed on the cleaning component, the transmission assembly is connected to the second cutting component, and is adapted to drive the second cutting component to rotate relative to the first cutting component as the cleaning component rotates.

[0008] Optionally, in the cleaning mechanism, both the first cutting member and the second cutting member are disposed on the cleaning member and can rotate around the rotation axis of the cleaning member. The transmission assembly drives the second cutting member to rotate around the target rotation axis simultaneously, wherein the target rotation axis is not parallel to the rotation axis of the cleaning member.

[0009] Optionally, in the cleaning mechanism, the cleaning component includes a cover rotatably connected to the cleaning member, and the transmission component is disposed inside the cleaning member, including a first transmission member and a second transmission member. The first transmission member connects the cleaning member and the second cutting member, and the second transmission member connects to the cover, and the first transmission member and the second transmission member have abutting portions.

[0010] The abutting portion is adapted to convert the rotation of the first transmission member around the rotation axis of the cleaning member as the cleaning member rotates into the rotation of the first transmission member around the target rotation axis, so as to drive the second cutting member to rotate around the target rotation axis.

[0011] Optionally, in the cleaning mechanism, the first transmission member includes a mating portion, and the second transmission member includes a guiding portion. The guiding portion and the mating portion together form the abutting portion.

[0019] Optionally, in the cleaning mechanism, the connecting rod is provided with a first anti-rotation part, and the second cutting member is provided with a second anti-rotation part that cooperates with the first anti-rotation part. The first anti-rotation part includes a first wedge-shaped surface, and the second anti-rotation part includes a second wedge-shaped surface that cooperates with the first wedge-shaped surface.

[0020] The rotation of the cleaning component drives the first transmission component and the second cutting component to rotate together. The second cutting component stops rotating under the action of external force, causing the first wedge surface and the second wedge surface to move relative to each other along the wedge direction, so that the first anti-rotation part and the second anti-rotation part separate.

[0031] The cleaning mechanism provided by this invention includes a cleaning component, a cutting component, and a transmission component. The rotation of the cleaning component drives the transmission component to rotate, and under the action of the transmission component, the second cutting component can rotate relative to the first cutting component, thereby realizing the cutting action. Therefore, the cutting component does not need to set up a separate cutting drive mechanism to realize the cutting action, which makes the cost of the cleaning mechanism lower. Moreover, the first and second cutting components are rotating and cooperating to cut, and there is a certain cutting angle between the first and second cutting components. Compared with linear reciprocating cutting components, it can effectively improve the self-cleaning effect of the cleaning mechanism. Attached Figure Description

[0057] Example 1

[0058] This embodiment provides a cleaning mechanism 100. Please refer to [link / reference]. Figures 1 to 4The cleaning mechanism 100 includes a cleaning component 1, a cutting component 2, and a transmission component 3. The cleaning component 1 includes a rotatable cleaning element 11, such as a cleaning roller brush, which cleans the surface to be cleaned by rotating the cleaning element 11. The cleaning element 11 has a cutting hole 1121. The cutting component 2 is located inside the cleaning element 11, making the structure more compact. The cutting component 2 includes a first cutting element 21 and a second cutting element 22. At least a portion of the second cutting element 22 protrudes from the cutting hole 1121 to the outside of the cleaning element 11. The first cutting element 21 and the second cutting element 22 cooperate to cut hair or other filamentous materials wrapped around the outside of the cleaning element 11. The transmission component 3 is located on the cleaning element 11 and is connected to the second cutting element 22, suitable for... As the cleaning component 11 rotates, the second cutting component 22 rotates relative to the first cutting component 21. The rotation of the cleaning component 11 drives the transmission component 3 to rotate, and under the action of the transmission component 3, the second cutting component 22 can rotate relative to the first cutting component 21, thereby realizing the cutting action. Therefore, when the cutting component 2 of the cleaning mechanism 100 realizes the cutting action, it is not necessary to set up a separate cutting drive mechanism, which makes the manufacturing cost of the cleaning mechanism 100 lower. Moreover, the first cutting component 21 and the second cutting component 22 are rotating and cooperating to cut, and there is a certain cutting angle between the first cutting component 21 and the second cutting component 22. Compared with the linear reciprocating cutting component, it is not easy to get hair tangled, which can effectively improve the self-cleaning effect of the cleaning mechanism 100.

[0059] To convert the rotation of the cleaning component 11 into the rotation of the cutting component 2, the first cutting component 21 and the second cutting component 22 can both be mounted on the cleaning component 11. When the cleaning component 11 rotates around its rotation axis, the first cutting component 21 and the second cutting component 22 can both rotate together with the cleaning component 11. At this time, the transmission component 3 can drive the second cutting component 22 to rotate around the target rotation axis at the same time. The target rotation axis refers to the rotation axis of the second cutting component 22 when the second cutting component 22 and the first cutting component 21 form a rotational cut. Furthermore, the target rotation axis is not parallel to the rotation axis of the cleaning component 11. Preferably, the target rotation axis is perpendicular to the rotation axis of the cleaning component 11, so that the second cutting component 22 rotates along the plane extending from the cutting hole 1121 to achieve the cutting of hair and other filamentous materials at the cutting hole 1121.

[0060] Specifically, for transmission component 3, such as Figure 5 and Figure 7As shown, the transmission assembly 3 includes a first transmission member 31 and a second transmission member 32, both of which are disposed within the cleaning member 11, resulting in a more compact structure and less space occupation. The first transmission member 31 connects the cleaning member 11 and the aforementioned second cutting member 22. The rotation of the cleaning member 11 drives the first transmission member 31 to rotate, simultaneously causing the second cutting member 22 to rotate. The cleaning assembly 1 also includes a cover 12 rotatably connected to the cleaning member 11, which forms part of the outer shell of the cleaning mechanism 100, or... The cover 12 is detachably mounted on the housing of the cleaning mechanism 100. The second transmission member 32 is connected to the cover 12 and is fixed relative to the cover 12. The cleaning member 11 can rotate around the second transmission member 32 as a rotation axis. The first transmission member 31 and the second transmission member 32 have abutting portions, which are adapted to convert the rotation of the first transmission member 31 around the rotation axis of the cleaning member 11 as it rotates with the cleaning member 11 into the rotation of the first transmission member 31 around the target placement axis, thereby driving the second cutting member 22 to rotate around the target rotation axis. When the cleaning member 11 rotates around the second transmission member 32, it drives the first transmission member 31 to rotate around the second transmission member 32 as a rotation axis. At the same time, when the first transmission member 31 rotates around the second transmission member 32, the second transmission member 32 can act on the first transmission member 31, causing the first transmission member 31 to rotate around the target rotation axis. When the first transmission member 31 is cylindrical, the target rotation axis is the central axis of the first transmission member 31.

[0061] Furthermore, combined Figure 9 and Figure 10 There are various specific implementations of the contact portion of the first transmission member 31 and the second transmission member 32. In one embodiment, the first transmission member 31 includes a mating portion 3111, and the second transmission member 32 includes a guiding portion 3211. The guiding portion 3211 and the mating portion 3111 interact to form the aforementioned contact portion. The mating portion 3111 includes a plurality of guide protrusions arranged circumferentially along the first transmission member 31. The guiding portion 3211 includes a spiral segment 3211a disposed on the periphery of the second transmission member 32. The spiral segment 3211a extends axially along the first transmission member 31. When the cleaning member 11 rotates, it drives the first transmission member 31 to rotate around the second transmission member 32, so that at least one guide protrusion can be engaged in the groove of the spiral segment 3211a. When the guide protrusion moves along the spiral groove, since the first transmission member 31 is in a stationary state, the spiral groove can apply a force to the guide protrusion in the axial direction of the second transmission member 32, thereby causing the second transmission member 32 to rotate around its own central axis.

[0062] The multiple guide protrusions include multiple guide ribs 3111a arranged along the axial direction of the first transmission member 31. The multiple guide ribs 3111a are all inclined in the axial direction of the first transmission member 31, and the inclination direction of each guide rib 3111a is consistent with the rotation direction of the spiral segment 3211a, so that the guide ribs 3111a and the spiral segment 3211a mesh with each other to better act on the second transmission member 32, so that the second transmission member 32 rotates and drives the second cutting member 22 to rotate, so as to cooperate with the first cutting member 21 to cut.

[0063] Of course, in another implementation, such as Figure 9 and Figure 10 As shown, the first transmission component 31 may include a worm gear 311, and the second transmission component 32 includes a worm 321 that meshes with the worm gear 311. The worm 321 extends along the axial direction of the cleaning component 11 to form the rotation axis of the cleaning component 11. The rotation center axis of the worm gear 311 forms the target rotation axis. Through the transmission of the worm gear 311 and the worm 321, the transmission is more stable, thereby making the cutting assembly 2 more stable when cutting and the cutting effect is better.

[0064] The connection method of the first transmission component 31, the second cutting component 22, and the cleaning component 11 is as follows: Figure 7 and Figure 8 The cleaning mechanism 100 also includes a connecting rod 4, with both ends of the connecting rod 4 rotatably mounted on the cleaning component 11. The first transmission component 31 and the second cutting component 22 are both sleeved on the connecting rod 4. The connecting rod 4 is tightly fitted with the first transmission component 31. When the first transmission component 31 rotates, it can drive the connecting rod 4 to rotate, thereby causing the second cutting component 22 to rotate through the connecting rod 4.

[0065] To prevent the connecting rod 4 from easily wearing against the cleaning component 11 during rotation, the cleaning mechanism 100 also includes a first sleeve and a second sleeve sleeved at both ends of the connecting rod 4. The first sleeve and the second sleeve are mounted on the cleaning component 11, and the connecting rod 4 can rotate relative to the first sleeve and the second sleeve. The first sleeve and the second sleeve can both be metal parts. The first sleeve and the second sleeve prevent the connecting rod 4 from easily rubbing against the cleaning component 11 during rotation, which can better protect the cleaning component 11 and make the installation between the cleaning component 11 and the connecting rod 4 less prone to failure and more reliable.

[0066] For the cutting assembly 2, the first cutting element 21 and the second cutting element 22 can be configured as cutting blades or serrated blades, etc. The first cutting element 21 is fixedly set to form a fixed tool, and the second cutting element 22 is rotated to form a moving tool. During the rotation, the second cutting element 22 has a cutting state that is in contact with the first cutting element 21 and a separating state that is far away from the first cutting element 21. In order to avoid the formation of a gap between the second cutting element 22 and the first cutting element 21 during the rotation, which would easily trap hair or other filamentous objects and make them difficult to cut, the first cutting element 21 and the second cutting element 22 should remain in contact when they are in the cutting state.

[0067] Specifically, in one embodiment, combined with Figure 11 and Figure 12 As shown, the cutting assembly 2 also includes an elastic element 5. The second cutting element 22 has a movable stroke along the axial direction of the first transmission element 31, that is, the second cutting element 22 can slide along the connecting rod 4. The elastic element 5 connects the connecting rod 4 and the second cutting element 22. The elastic element 5 allows the second cutting element 22 to slide along the connecting rod 4, thereby automatically adjusting the fit between the second cutting element 22 and the first cutting element 21 during the rotation of the second cutting element 22, so that the second cutting element 22 can fit with the first cutting element 21 to avoid getting stuck with hair or other filamentous objects that are difficult to cut.

[0068] Specifically, the elastic element 5 can be configured as a spring, which is sleeved on the outside of the connecting rod 4, and its two ends along its extension and contraction direction respectively abut against the connecting rod 4 and the second cutting element 22. The first cutting element 21 is located on the side of the second cutting element 22 facing away from the elastic element 5, so that the second cutting element 22 can be abutted against the end face of the first cutting element 21 by the spring. When the first cutting element 21 and the second cutting element 22 are in close contact, the second cutting element 22 will be subjected to the reaction force of the first cutting element 21, compressing the spring and causing the second cutting element 22 to move away from the first cutting element 21. The spring moves in the direction of 1 to prevent the first cutting component 21 and the second cutting component 22 from being too tightly attached, resulting in excessive rotational friction and excessive machine power. When the gap between the first cutting component 21 and the second cutting component 22 is too large, the spring can abut against the second cutting component 22 under its own elastic force, causing the second cutting component 22 to move towards the first cutting component 21, thereby making the first cutting component 21 and the second cutting component 22 fit together to better cut hair and other filamentous materials. This not only protects the better cutting effect but also avoids hair getting caught in the cutting component 2, resulting in a better cutting effect.

[0069] In another embodiment, such as Figure 13As shown, the first transmission member 31 can also be configured to move relative to the connecting rod 4. The two ends of the elastic member 5 can respectively abut against the cleaning member 11 and the first end of the first transmission member 31. The second cutting member 22 is disposed between the second end of the first transmission member 31 and the first cutting member 21. Through the extension and contraction of the spring, the first transmission member 31 abuts against the second cutting member 22 to move and fit against the first cutting member 21. The working principle is similar to that described above and will not be repeated here.

[0070] Furthermore, if the cutting component 2 encounters a hard obstacle, such as a stone or hardware, and gets stuck during the cutting process, the second cutting component 22 will be unable to continue rotating under the action of the obstacle. In this case, in order to better protect the transmission component 3 and the cleaning component 11, the first transmission component 31 should be kept able to continue rotating to prevent the cleaning component 11 from getting stuck, which could lead to the driver that drives the cleaning component 11 to rotate getting stuck or even damaged.

[0071] Preferably, combined with Figure 14 and Figure 15 As shown, a first anti-rotation part 41 is provided on the connecting rod 4, and a second anti-rotation part 221 is provided on the second cutting member 22 to cooperate with the first anti-rotation part 41. The first anti-rotation part 41 includes a first wedge-shaped surface 412, and the second anti-rotation part 221 includes a second wedge-shaped surface 2212 that cooperates with the first wedge-shaped surface 412. When the cleaning component 11 is working normally, its rotation drives the first transmission component 31 and the second cutting component 22 to rotate together, allowing the second cutting component 22 to perform cutting actions. When the second cutting component 22 stops rotating due to external force (such as being jammed by an obstacle), the first transmission component 31 and the connecting rod 4 continue to rotate under the drive of the cleaning component 11, allowing the connecting rod 4 to rotate relative to the second cutting component 22. The first wedge surface 412 and the second wedge surface 2212 can move relative to each other along the wedge direction, causing the first anti-rotation part 41 and the second anti-rotation part 221 to separate. After the first anti-rotation part 41 and the second anti-rotation part 221 separate, the second cutting component 22 no longer rotates with the rotation of the connecting rod 4, and the second cutting component 22 remains jammed and stationary, while the first transmission component 31 and the connecting rod 4 continue to rotate. The operation of the cleaning component 11 is not affected, better protecting the cleaning component 11, the transmission component 3, and the driver, and extending the service life of the cleaning mechanism 100.

[0072] Furthermore, combined Figure 14 and Figure 15As shown, the first anti-rotation part 41 includes a wedge-shaped block 411 sleeved on the outside of the connecting rod 4. The wedge-shaped block 411 abuts against the end of the first transmission member 31 and is tightly fitted with the connecting rod 4. A movement area for the connecting rod 4 is formed inside the cleaning member 11. When the second cutting member 22 is jammed, the connecting rod 4 can move along its length direction, so that the first anti-rotation part 41 and the second anti-rotation part 221 can be separated, thereby preventing the rotation of the connecting rod 4 from driving the second cutting member 22 to rotate. The first wedge-shaped surface 412 is provided on the wedge-shaped block 411 and is inclined along the axial direction of the first transmission member 31. The second anti-rotation part 221 includes a wedge-shaped block 411 sleeved on the outside of the connecting rod 4. The second anti-rotation part 221 includes a wedge-shaped block 411 sleeved on the outside of the connecting rod 4. The first anti-rotation part 411 is sleeved on the end of the first transmission member 31 and is tightly fitted with the connecting rod 4. The second anti-rotation part 221 includes a wedge-shaped block 411 sleeved on the outside of the connecting rod 4. The second anti-rotation part 221 is sleeved on the second cutting member 22. The first wedge-shaped surface 412 is provided on the wedge-shaped block 411 and is inclined along the axial direction of the first transmission member 31. The second anti-rotation part 221 includes a wedge-shaped block 411 sleeved on the second cutting member 22. The rotating hole 2211 on the component 22 is non-circular. The rotating hole 2211 is connected to the wedge block 411 to form an anti-rotation fit. A wedge-shaped protrusion 2213 is formed on the hole wall of the rotating hole 2211. The second wedge surface 2212 is provided on the wedge protrusion 2213 and is in close contact with the first wedge surface 412. When the second cutting component 22 is stuck, the wedge protrusion 2213 is stationary. The wedge block 411 rotates relative to the wedge protrusion 2213 under the drive of the connecting rod 4, and causes the first wedge surface 412 and the second wedge surface 2212 to move in the wedge direction, so that the connecting rod 4 is displaced along its length. At this time, the elastic element 5 can be connected between the cleaning element 11 and the second transmission element 32. When the connecting rod 4 moves along its length, it drives the first transmission element 31 to move as well, thereby compressing the elastic element 5. When the second cutting element 22 is released from jamming, the elastic element 5 pushes the first transmission element 31 to move under the action of its own elastic restoring force, thereby driving the connecting rod 4 to reset, so that the first wedge surface 412 and the second wedge surface 2212 cooperate, so that the second cutting element 22 can rotate again and cut, making the self-adjustment capability of the cleaning mechanism 100 stronger.

[0073] Furthermore, the wedge block 411 includes a mounting platform 4111 and a wedge-shaped boss 4112 protruding from the mounting platform 4111. The mounting platform 4111 can be integrally set with the connecting rod 4, or the mounting platform 4111 and the connecting rod 4 can be tightly fitted together. The first wedge-shaped surface 412 is set on the wedge-shaped boss 4112. The mounting platform 4111 is sleeved on the outside of the connecting rod 4 and abuts against the first transmission member 31 on one side. The rotating hole 2211 is sleeved on the outside of the wedge-shaped boss 4112. The second cutting member 22 abuts against the other side of the mounting platform 4111 and the first cutting member 21 on both sides along the axial direction of the first transmission member 31. The mounting platform 4111 presses the second cutting member 22 against the first cutting member 21, so that the second cutting member 22 and the first cutting member 21 fit tightly together, thereby improving the cutting effect and avoiding hair getting caught. Furthermore, the top of the wedge-shaped boss 4112 is flat along the protruding direction. When the second cutting member 22 is jammed, this flat surface can abut against the second cutting member 22, allowing the connecting rod 4 to rotate better and preventing scratches on the second cutting member 22. Multiple wedge-shaped bosses 4112 can be provided, and multiple wedge-shaped bosses 4112 are arranged circumferentially along the connecting rod 4, making the second cutting member 22 more stable when rotating together with the connecting rod 4.

[0074] For the cleaning component 11, to facilitate the installation of the transmission assembly 3, the cleaning component 11 can be configured as a separate unit. Specifically, as follows: Figure 3 As shown, the cleaning component 11 includes a main body 111 and a cover 112. The main body 111 has an installation port 1111 on one side of its circumferential direction of rotation. Preferably, the installation port 1111 is located in the middle of the main body 111. The cover 112 is detachably covered at the installation port 1111. The cutting hole 1121 is formed on the cover 112. The connecting rod 4 is clamped and fixed inside the main body 111 by the main body 111 and the cover 112. During installation, the first transmission component 31 and the second cutting component 22 can be sleeved on the connecting rod 4 first, and then the first sleeve and the second sleeve can be sleeved on both ends of the connecting rod 4 respectively. Then, the two ends of the connecting rod 4 sleeved with the first sleeve and the second sleeve can be installed on the main body 111 respectively. Finally, the cover 112 is placed on the installation port 1111 to completely fix the connecting rod 4.

[0075] Specifically, in combination Figure 7 and Figure 8As shown, the main body 111 is provided with two first clamping parts 1112, which clamp the first sleeve and the second sleeve on one side respectively. Each of the two first clamping parts 1112 includes a first clamping groove on the inner sidewall of the main body 111. The cover 112 is provided with two second clamping parts 1122, which clamp the first sleeve and the second sleeve on the other side respectively. Each of the two second clamping parts 1122 includes a second clamping groove on the inner sidewall of the cover 112. When the cover 112 is placed on the installation opening 1111, one of the first clamping parts 1112 and one of the second clamping parts 1122 cooperate to jointly clamp the first sleeve, and the other first clamping part 1112 and the other second clamping part 1122 cooperate to jointly clamp the second sleeve. The openings of the two first clamping grooves and the two second clamping grooves are opposite to each other, thereby fixing the first sleeve and the second sleeve, which is convenient for installation.

[0076] Furthermore, when the cutting hole 1121 is formed on the cover 112, the aforementioned first cutting member 21 can be disposed between the first sleeve and the first transmission member 31. Of course, the first cutting member 21 can also be disposed between the second sleeve and the first transmission member 31. The cover 112 is also provided with a second cutting member 22, at least a portion of which protrudes from the cutting hole 1121 to the outside of the cleaning member 11, thereby cutting hair and other filamentous materials around the cutting hole 1121.

[0077] Moreover, see also Figure 1 A cutting groove is formed on the outer side of the cover 112, and a cutting hole 1121 is located in the cutting groove. Multiple guide ribs are provided on the outer periphery of the main body 111. The multiple guide ribs are inclined and extended in the direction of the cutting groove along the axial direction of the main body 111. Hair and other filamentous materials on the outside of the cleaning component 11 can be guided into the cutting groove through the guide ribs, so that the cutting component 2 can cut the hair and other filamentous materials. The treatment of hair and other filamentous materials is more convenient and cleaner.

[0078] It is understandable that, such as Figure 16 As shown, the cleaning assembly 1 also includes a bearing 13, with its two ends along its axial direction abutting against the cleaning component 11 and the cover 12 respectively, thus confining the bearing 13 between the ends of the cover 12 and the cleaning component 11. The second transmission component 32 is sleeved on the inner side of the inner ring of the bearing 13, and the cleaning component 11 is sleeved on the outer side of the outer ring of the bearing 13. The connection through the bearing 13 makes the rotation of the cleaning component 11 smoother and easier to clean.
