Technical Field

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

[0002] In related technologies, after the cleaning equipment cleans inside the base station, some moisture and impurities will penetrate the inside of the mop. Due to the mixing of impurities and moisture between the contact surfaces of the mop and the roller, the coefficient of friction drops sharply, which may cause the mop to jam or slip, resulting in abnormal friction noise and other problems.

[0007] According to the present invention, the cleaning component is provided with a first anti-slip protrusion on the drive shaft and / or driven shaft, and the number of the first anti-slip protrusion is limited. By utilizing the first anti-slip protrusion in conjunction with a plurality of second anti-slip protrusions on the mopping component, the driving force and anti-slip capability can be improved during the operation of the cleaning component, thereby solving the problems of insufficient driving force and slippage noise caused by the decrease in friction between the contact surface of the mopping component and the drive shaft or driven shaft.

[0012] In some specific embodiments, the circumferential surface where the groove of the annular groove is located is used as the reference surface, and the first anti-slip protrusion does not extend beyond the reference surface.

[0013] In some specific embodiments, the annular groove has two groove sidewalls disposed opposite to each other in the first direction, and the first anti-slip protrusion is a rib extending along the first direction, with the two ends of the rib connected to the two groove sidewalls respectively in the first direction.

[0014] In some specific embodiments, the annular groove is trapezoidal in shape on the longitudinal section of its axis, the first anti-slip protrusion is a trapezoidal rib with the same longitudinal section shape as the annular groove, and the second anti-slip protrusion is a trapezoidal protrusion with the same longitudinal section shape as the annular groove.

[0015] In some examples, the annular groove is located at the center of the drive shaft or the driven shaft in the first direction, and a plurality of second anti-slip protrusions are located at the center of the dragging member in the first direction.

[0016] In some specific examples, there are multiple annular grooves arranged in the first direction, and the inner peripheral wall of the wiping member has multiple mounting areas arranged in the first direction. The multiple mounting areas correspond one-to-one with the positions of the multiple annular grooves, and each mounting area is provided with multiple second anti-detachment protrusions.

[0017] In some specific embodiments, the cross-sectional shape of the second anti-slip protrusion cut by a plane perpendicular to the first direction is triangular or trapezoidal.

[0018] In some specific embodiments, the number of the first anti-slip protrusions in the drive shaft assembly is one, and the first anti-slip protrusion is disposed on the drive shaft.

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] The following is for reference. Figures 1-12 This invention describes a cleaning component 100 and a cleaning device 1000 according to embodiments of the present invention. The cleaning component 100 is used to install on the cleaning device 1000, wherein the cleaning device 1000 can be a self-propelled cleaning robot or a handheld floor scrubber.

[0045] Please see Figures 1-4 The cleaning assembly 100 according to an embodiment of the present invention includes: a mounting bracket 10, a drive shaft assembly, and a mopping component 40. For example, the cleaning assembly 100 may be a tracked cleaning assembly.

[0046] The drive shaft assembly includes a drive shaft 20 and a driven shaft 30, both of which are rotatably mounted on the mounting bracket 10. The axial directions of the drive shaft 20 and the driven shaft 30 are both along a first direction, and the drive shaft 20 and the driven shaft 30 are spaced apart in a second direction, which is perpendicular to the first direction.

[0047] The first direction is Figure 3 The F1 direction shown is the second direction. Figure 3 The F2 direction is shown. The first direction can be left-right or front-back, and the second direction can be left-right or front-back. Taking the first direction as left-right and the second direction as front-back as an example, the axial directions of the drive shaft 20 and the driven shaft 30 both extend in the left-right direction, and they are arranged at intervals in the front-back direction. The left and right ends of the drive shaft 20 and the driven shaft 30 are rotatably supported on the mounting bracket 10.

[0048] The wiping component 40 is arranged around the outer periphery of the drive shaft assembly and is in drive engagement with the drive shaft 20 and the driven shaft 30. The drive shaft 20 is used to connect with the drive component to drive the drive shaft 20 to rotate. The drive component may be located in the main body of the cleaning equipment.

[0049] When the cleaning equipment performs a cleaning task, the cleaning component 100 contacts the surface to be cleaned. When the cleaning component 100 is running, the driving component drives the drive shaft 20 to rotate. The friction between the contact surface of the drive shaft 20 and the mopping component 40 can drive the mopping component 40 to move. The friction between the contact surface of the mopping component 40 and the driven shaft 30 can drive the driven shaft 30 to rotate, so that the cleaning component 100 can perform the cleaning function of the surface to be cleaned.

[0050] The drive shaft 20 and / or driven shaft 30 are provided with first anti-slip protrusions 22. The number of first anti-slip protrusions 22 along the same circumferential direction of the drive shaft 20 or the driven shaft 30 is less than or equal to 8. The inner peripheral wall of the mopping member 40 is provided with a plurality of second anti-slip protrusions 42 arranged circumferentially. During the operation of the cleaning assembly 100, the second anti-slip protrusions 42 cooperate with the first anti-slip protrusions 22. For example, the cooperation between the second anti-slip protrusions 42 and the first anti-slip protrusions 22 can be that the two abut against each other circumferentially.

[0051] The cooperation between the first anti-slip protrusion 22 and the second anti-slip protrusion 42 can reduce the slippage of the mopping component 40 along the circumferential direction of the drive shaft assembly, improve the anti-slip capability of the cleaning component 100, and also provide driving force between the drive shaft assembly and the mopping component 40 to a certain extent.

[0052] According to the present invention, the cleaning assembly 100, by providing a first anti-slip protrusion 22 on the drive shaft 20 and / or the driven shaft 30 and limiting the number of the first anti-slip protrusions 22, and by utilizing the first anti-slip protrusions 22 in cooperation with a plurality of second anti-slip protrusions 42 on the mopping member 40, can improve the driving force and anti-slip capability during the operation of the cleaning assembly 100, thereby solving the problems of insufficient driving force and slippage noise caused by the decrease in friction between the contact surface of the mopping member 40 and the drive shaft 20 or the driven shaft 30.

[0053] Please refer to Figure 3 and further refer to Figure 6 The mounting bracket 10 includes a main bracket 11 and a secondary bracket 12. The two ends of the drive shaft 20 in the first direction are respectively connected to the two ends of the main bracket 11, and the two ends of the driven shaft 30 in the first direction are respectively connected to the two ends of the secondary bracket 12. The drive shaft 20 and the driven shaft 30 are arranged at intervals along the second direction.

[0054] The mounting bracket 10 is also equipped with components such as positioning pin 111 and latch 121 to facilitate the positioning and installation of the cleaning component 100.

[0055] Please refer to this again. Figure 3 The wiping element 40 is arranged around the outer periphery of the drive shaft assembly. The wiping element 40 can be a single-layer structure or a multi-layer structure, such as a double-layer structure.

[0056] If the mopping component 40 is a single-layer structure, the outer side of the mopping component 40 is made of a material with cleaning function, and the inner side is made of a material with a certain roughness, so as to fit with the drive shaft 20 and the driven shaft 30.

[0057] If the mopping component 40 has a multi-layer structure, the outermost layer is a material layer with cleaning function, and the innermost layer is a material layer with a certain roughness so as to be in contact with the drive shaft 20 and the driven shaft 30. A plurality of second anti-slip protrusions 42 are provided on the inner peripheral wall of the innermost layer.

[0058] If the mopping component 40 has a double-layer structure, the mopping component 40 includes a mopping body 401 and an inner liner 402. The inner liner 402 is located inside the mopping body 401, and the outer peripheral wall of the inner liner 402 is connected to the inner peripheral wall of the mopping body 401. A plurality of second anti-slip protrusions 42 are located on the inner peripheral wall of the inner liner 402.

[0059] In some embodiments, such as Figures 5-7 As shown, the number of first anti-slip protrusions 22 along the same circumference of the drive shaft 20 or driven shaft 30 is less than the number of second anti-slip protrusions 42.

[0060] The number of first anti-slip protrusions 22 along the same circumference of the drive shaft 20 or driven shaft 30 can be any number not exceeding 8. For example, for the drive shaft 20, no more than 8 first anti-slip protrusions 22 are arranged circumferentially along the drive shaft 20, such as 6 first anti-slip protrusions 22 arranged in a circle along the circumference of the drive shaft 20, or 2 first anti-slip protrusions 22 arranged circumferentially along the drive shaft 20.

[0061] It should be noted that in some embodiments of this disclosure, the first anti-slip protrusion 22 may be provided only on the drive shaft 20. Since the drive shaft 20 is the part that provides the driving source for the dragging member 40, the more obvious the force between it and the dragging member 40, the lower the probability of the dragging member 40 slipping relative to the transmission shaft assembly. Therefore, providing the first anti-slip protrusion 22 on the drive shaft 20 can improve the transmission reliability between the transmission shaft assembly and the dragging member 40 while simplifying the structure. Of course, in other embodiments, the first anti-slip protrusion 22 may be provided only on the driven shaft 30, or both the drive shaft 20 and the driven shaft 30 may be provided with the first anti-slip protrusion 22.

[0062] The following explanation uses the example of the first anti-slip protrusion 22 being located on the drive shaft 20.

[0063] If there is only one first anti-slip protrusion 22, then during the operation of the cleaning component 100, the first anti-slip protrusion 22 will rotate with the drive shaft 20, and the first anti-slip protrusion 22 will intermittently cooperate with a portion of the second anti-slip protrusion 42 to play an anti-slip and assist role. Specifically, after the drive shaft 20 rotates to a certain angle, for example, when the first anti-slip protrusion 22 is located in the space between the drive shaft 20 and the driven shaft 30, the first anti-slip protrusion 22 disengages from the second anti-slip protrusion 42 on the mopping component 40. After the drive shaft 20 continues to rotate, the first anti-slip protrusion 22 will engage with the second anti-slip protrusion 42 again, thus providing anti-slip and assist functions once more. If the cleaning assembly 100 operates in an uneven environment with sticky stains, the mopping component 40 may slip from the drive shaft 20 or the driven shaft 30 due to environmental factors. In this case, the intermittent engagement of the first anti-slip protrusion 22 and the second anti-slip protrusion 42 can promptly correct the engagement between the mopping component 40 and the drive shaft 20 or the driven shaft 30, making the entire cleaning assembly 100 operate more reliably and ensuring the cleaning effect and efficiency of the cleaning assembly 100.

[0064] If there are two or more first anti-slip protrusions 22, by reasonably selecting the setting position of the first anti-slip protrusions 22, a portion of the first anti-slip protrusions 22 can always cooperate with the second anti-slip protrusions 42 during the entire operation of the cleaning component 100, so as to play the role of anti-slip and assist at all times. If the cleaning component 100 works in an uneven environment with sticky stains, the mopping component 40 may slip with the drive shaft 20 or driven shaft 30 due to environmental factors. At this time, the cooperation of the first anti-slip protrusions 22 and the second anti-slip protrusions 42 can correct the cooperation between the mopping component 40 and the drive shaft 20 or driven shaft 30 in time, so that the operation of the entire cleaning component 100 is more reliable, thereby ensuring the cleaning effect and cleaning efficiency of the cleaning component 100.

[0065] It is understandable that the more first anti-slip protrusions 22 there are in the same circumferential direction, the better the anti-slip and assist effect will be. However, interference problems may occur. For example, during operation, multiple first anti-slip protrusions 22 and multiple second anti-slip protrusions 42 are more likely to misalign. Once multiple first anti-slip protrusions 22 and second anti-slip protrusions 42 are misaligned, it will be more difficult to get the first anti-slip protrusions 22 and second anti-slip protrusions 42 back to their aligned positions. This may also aggravate the wear of the first anti-slip protrusions 22 and second anti-slip protrusions 42 and reduce the service life of the cleaning component 100. Therefore, in this embodiment, the number of first anti-slip protrusions 22 on the same axis and in the same circumferential direction does not exceed 8.

[0066] In some specific embodiments, refer again Figures 5-7 The height of the first anti-slip protrusion 22 is H1, and the height of the second anti-slip protrusion 42 is H2. H1 and H2 satisfy the condition: 0.5H2≤H1≤H2. That is, the height of the first anti-slip protrusion 22 is between half the height of the second anti-slip protrusion 42 and the height of the second anti-slip protrusion 42. For example, H1 can be 0.5H2, 0.6H2, 0.7H2, 0.8H2, 0.9H2, or H2.

[0067] It is understood that the "height of the first anti-slip protrusion 22" here refers to the height of the first anti-slip protrusion 22 protruding from the surface on which it is mounted on the drive shaft 20 or driven shaft 30. This surface is referred to as the first mounting surface, which can be located within the cylindrical surface constructed by the maximum outer diameter of the shaft on which the first anti-slip protrusion 22 is located. Similarly, the "height of the second anti-slip protrusion 42" refers to the height of the second anti-slip protrusion 42 protruding from the surface on which it is mounted on the inner peripheral wall of the dragging member 40.

[0068] In the above technical solution, by limiting the protrusion height of the first anti-slip protrusion 22 and the protrusion height of the second anti-slip protrusion 42 to meet the above conditions, the cooperation between the first anti-slip protrusion 22 and the second anti-slip protrusion 42 can be made more reliable, so that there will be no situation of disengagement. Furthermore, when the first anti-slip protrusion 22 and the second anti-slip protrusion 42 are in cooperation, the mopping member 40 with the second anti-slip protrusion 42 will not be partially lifted up, causing the partially lifted mopping member 40 to have uneven contact with the ground, thereby affecting the cleaning function of the cleaning component 100.

[0069] In some specific embodiments, there are multiple first anti-slip protrusions 22. The distance between two adjacent first anti-slip protrusions 22 along the circumferential direction of the drive shaft 20 or driven shaft 30 is L1, and the distance between two adjacent second anti-slip protrusions 42 along the circumferential direction of the dragging member 40 is L2. L1 is greater than or equal to an integer multiple of L2.

[0070] Since the number of first anti-slip protrusions 22 on the same axis and in the same circumferential direction does not exceed 8, the first anti-slip protrusions 22 cannot continuously engage with all the second anti-slip protrusions 42. During the engagement process, there will be a certain distance L1 between two adjacent first anti-slip protrusions 22 in the circumferential direction of their respective axes. L1 is numerically greater than the distance L2 between two adjacent second anti-slip protrusions 42 in the circumferential direction of the mopping member 40, and L1 is greater than or equal to an integer multiple of L2. This distance setting can ensure that the first anti-slip protrusions 22 can engage with the second anti-slip protrusions 42 in a staggered manner during the operation of the cleaning component 100, avoiding the problem of the first anti-slip protrusions 22 and the second anti-slip protrusions 42 colliding at their top ends due to improper distance setting, which could lead to the mopping member 40 falling off from the drive shaft 20 or the driven shaft 30.

[0071] In some embodiments, the spacing between any two adjacent second anti-slip protrusions 42 in the circumferential direction of the wiping member 40 is equal, that is, a plurality of second anti-slip protrusions 42 are evenly and spaced apart in the circumferential direction of the wiping member 40.

[0072] like Figure 3 and Figure 4As shown, in some embodiments, the outer peripheral wall of the drive shaft 20 and / or driven shaft 30 is provided with an annular groove 21 extending circumferentially therein, and the first anti-slip protrusion 22 is provided in the annular groove 21. In the above technical solution, by providing an annular groove 21 extending circumferentially on the outer peripheral wall of the drive shaft 20 or driven shaft 30, and placing the first anti-slip protrusion 22 in this annular groove 21, on the one hand, it is convenient for the first anti-slip protrusion 22 and the second anti-slip protrusion 42 to cooperate here, which can improve the driving force and anti-slip ability during the operation of the cleaning component 100, thereby solving the problem of insufficient driving force and slippage noise caused by the decrease in friction between the contact surface of the mopping component 40 and the drive shaft 20 or driven shaft 30. On the other hand, the annular groove 21 always... The second anti-slip protrusion 42 engages and can limit the movement of the second anti-slip protrusion 42 along the axial direction of the drive shaft 20 or driven shaft 30. If the first anti-slip protrusion 22 and the second anti-slip protrusion 42 disengage, the second anti-slip protrusion 42 can continue to extend into the annular groove 21. This ensures that the wiping member 40 is always in contact with the drive shaft 20 or driven shaft 30, and will not be lifted up by the contact between the outer peripheral wall of the drive shaft 20 or driven shaft 30 and the second anti-slip protrusion 42, thus preventing the wiping member 40 from disengaging from the drive shaft 20 or driven shaft 30.

[0073] In some specific embodiments, reference is made to Figures 9-11 With the circumferential surface of the groove 212 of the annular groove 21 as the reference surface, the first anti-slip protrusion 22 does not exceed the reference surface.

[0074] In other words, the first anti-slip protrusion 22 is inside the groove 212, and the cooperation between the first anti-slip protrusion 22 and the second anti-slip protrusion 42 is also within the annular groove 21. This ensures that during the operation of the cleaning component 100, the wiping component 40 can always be in flat contact with the drive shaft 20 or the driven shaft 30 without any local protrusions, thus ensuring the operational reliability of the cleaning component 100. This also ensures that the cleaning component 100 can always fit well with the surface to be cleaned, guaranteeing the cleaning effect, and that the cleaning component 100 can always be in good contact with the scraper that removes the dirt, achieving real-time self-cleaning.

[0075] Please refer to this again. Figure 3 and Figure 4 , Figure 10 and Figure 11 In some specific embodiments, the annular groove 21 has two groove sidewalls 211 arranged opposite to each other in a first direction, and the first anti-slip protrusion 22 is a rib extending in the first direction, with the two ends of the rib connected to the two groove sidewalls 211 respectively in the first direction.

[0076] In other words, the two ends of the first anti-slip protrusion 22 extending along the first direction respectively extend to and connect with the two groove sidewalls 211. This configuration can improve the deformation resistance of the first anti-slip protrusion 22, so that during the cooperation between the first anti-slip protrusion 22 and the second anti-slip protrusion 42, the annular groove 21 and the first anti-slip protrusion 22 can more reliably limit the second anti-slip protrusion 42 in the first direction, effectively preventing the second anti-slip protrusion 42 from detaching from the annular groove 21, thereby preventing the dragging member 40 from detaching from the drive shaft 20 or the driven shaft 30.

[0077] Reference Figure 10 In some specific embodiments, the annular groove 21 is trapezoidal in shape on the longitudinal section of its axis, that is, the cross-section of the annular groove 21 cut by the plane passing through the axis of its axis is trapezoidal, wherein "the plane passing through the axis of its axis" means that the axis of its axis is located in this plane. The first anti-slip protrusion 22 is a trapezoidal rib with the same longitudinal cross-sectional shape as the annular groove 21, and the second anti-slip protrusion 42 is a trapezoidal protrusion with the same longitudinal cross-sectional shape as the annular groove 21.

[0078] On the longitudinal section of the annular groove 21, the first anti-slip protrusion 22 is a trapezoidal rib with the same longitudinal section shape as the annular groove 21, and the second anti-slip protrusion 42 has the same longitudinal section shape as the annular groove 21, both being trapezoidal.

[0079] This design increases the contact area between the second anti-slip protrusion 42 and the two sidewalls 211 of the annular groove 21, thereby increasing the friction between them and effectively suppressing the slippage of the mopping component 40. On the other hand, the two sidewalls 211 of the annular groove 21 guide the second anti-slip protrusion 42, keeping it inserted into the annular groove 21. This makes the cooperation between the first anti-slip protrusion 22 and the second anti-slip protrusion 42 smoother when the cleaning component 100 is working.

[0080] like Figure 9 and Figure 10 As shown, in some examples, the annular groove 21 is located at the center of the drive shaft 20 or the driven shaft 30 in the first direction, and a plurality of second anti-slip protrusions 42 are located at the center of the drag member 40 in the first direction.

[0081] When there is only one annular groove 21, the annular groove 21 is located in the middle of the drive shaft 20 or driven shaft 30 in the first direction. The inner peripheral wall of the mopping member 40 has a mounting area 41 corresponding to the position of the annular groove 21. The mounting area 41 is provided with a plurality of second anti-slip protrusions 42. This design allows the first anti-slip protrusion 22 and the second anti-slip protrusion 42 to cooperate in the middle of the entire cleaning assembly 100 in the first direction when the cleaning assembly 100 is working. The assistance generated by the cooperation of the first anti-slip protrusion 22 and the second anti-slip protrusion 42 can act in the middle of the first direction, which is conducive to the mopping member 40 and the drive shaft 20 or driven shaft 30 fitting together.

[0082] In some specific examples, there are multiple annular grooves 21, which are arranged in a first direction. The inner peripheral wall of the wiping member 40 has multiple mounting areas 41 arranged in the first direction. The multiple mounting areas 41 correspond one-to-one with the positions of the multiple annular grooves 21. Each mounting area 41 is provided with multiple second anti-detachment protrusions.

[0083] When there are multiple annular grooves 21, the multiple annular grooves 21 are arranged in a first direction. Each annular groove 21 has a first anti-slip protrusion 22. The inner peripheral wall of the mopping component 40 has multiple mounting areas 41 corresponding one-to-one with the positions of the multiple annular grooves 21. Each mounting area 41 has multiple second anti-detachment protrusions. This design ensures that when the cleaning assembly 100 is working, each annular groove 21 has a first anti-slip protrusion that cooperates with multiple second anti-slip protrusions, preventing the mopping component 40 from slipping against the drive shaft 20 or driven shaft 30 during operation, further improving the stability of the cleaning assembly 100.

[0084] In some specific examples, refer to Figures 5-7 The cross-sectional shape of the second anti-slip protrusion 42 cut by a plane perpendicular to the first direction is triangular or trapezoidal.

[0085] On a plane perpendicular to the first direction, the cross-section of the second anti-slip protrusion 42 is triangular or trapezoidal, which allows two adjacent second anti-slip protrusions 42 to form a mating groove 43, facilitating misalignment with the first anti-slip protrusion 22. This avoids the problem that the mopping component 40 would partially protrude due to the collision between the top of the first anti-slip protrusion 22 and the top of the second anti-slip protrusion 42, resulting in uneven contact between the cleaning component 100 and the ground, thus affecting the cleaning function of the cleaning component 100.

[0086] In some specific embodiments, the number of the first anti-slip protrusion 22 of the drive shaft assembly is one. The first anti-slip protrusion 22 is provided on the drive shaft 20, which makes the structure simpler and easier to process, and helps to reduce production costs.

[0087] Reference Figure 12The cleaning device 1000 according to an embodiment of the present utility model includes a device body 500 and a cleaning component 100 according to the above embodiment, wherein the cleaning component 100 is disposed on the device body 500.

[0088] According to the present utility model, the cleaning device 1000, by adopting the cleaning component 100 of the above embodiment, enables the first anti-slip protrusion 22 to cooperate with a plurality of second anti-slip protrusions 42 on the mopping member 40 during operation, thereby solving the problems of insufficient driving force and slippage noise caused by the decrease in friction between the contact surface of the mopping member 40 and the drive shaft 20 or driven shaft 30.

[0089] In some embodiments, the cleaning device 1000 is a cleaning robot. The device body 500 is equipped with wheels 51, which allows the cleaning robot to move to the area to be cleaned according to the cleaning task.
