Description

Technical Field

[0001] The present application relates to the technical field of floor cleaning, and in particular to a cleaning component and a cleaning device. Background Art

[0003] The sweeping robot is provided with a cleaning component, which includes a roller and a scraper. A roller mop is sleeved on the outer periphery of the roller, which is mainly used to clean the stains on the ground. The scraper abuts against the roller mop and is used to scrape out the dirty water and stains on the roller mop. However, with the long-term use of the scraper, the part where the scraper contacts the mop is prone to wear, resulting in the scraper being unable to press the mop, resulting in the problem of scraper failure. In order to solve the above problems, Chinese patent CN218606412U discloses a cleaning component of a sweeping robot and a sweeping robot, wherein an elastic member is provided between the scraper and the outer shell of the cleaning component, so that the scraper has a tendency to move toward the roller mop. When the scraper is worn, the scraper still abuts against the roller mop under the elastic force of the elastic member, thereby avoiding the problem of scraper failure.

[0004] However, in Chinese patent CN218606412U, due to the elastic force exerted by the elastic member on the scraper, when the force of the scraper against the roller mop is too large, the roller may be stuck. Utility Model Content

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0040] See also Figures 1 to 9 As shown, according to an embodiment of the present application, a cleaning device is provided, which may be, for example, a sweeper or a scrubber, etc. The cleaning device includes a cleaning assembly, which includes a mounting bracket 10, a roller component 30, a scraper 20, an elastic component 40, and a limiting component 50.

[0041] The mounting bracket 10 is provided with a mounting space 13. The roller component 30 includes a roller body 31 and a roller mop 32. The roller body 31 is rotatably connected in the mounting space 13, and the roller mop 32 is arranged on the outer periphery of the roller body 31. The first end of the scraper 20 is movably connected to the mounting bracket 10, and the second end of the scraper 20 opposite to the first end abuts against the roller mop 32. The elastic component 40 is arranged between the mounting bracket 10 and the scraper 20, and the elastic component 40 applies elastic force to the scraper 20 so that the second end of the scraper 20 has a tendency to move toward the roller mop 32. The limiting component 50 is arranged between the mounting bracket 10 and the scraper 20, and the limiting component 50 is used to limit the maximum displacement of the scraper 20 moving toward the roller mop 32.

[0042] In this embodiment, when the cleaning device is cleaning, the second end of the scraper 20 abuts against the roller mop 32 to scrape off the stains and sewage on the roller mop 32. When the second end of the scraper 20 is worn, since the elastic component 40 is provided between the mounting bracket 10 and the scraper 20, the elastic component 40 is in a compressed state in the initial state, and the elastic component 40 applies an elastic force to the scraper 20 in order to restore to an uncompressed state. At the same time, since the first end of the scraper 20 is movably mounted on the mounting bracket 10, the elastic force applied by the elastic component 40 to the scraper 20 can make the worn scraper 20 abut against the roller mop 32 again.

[0043] In addition, due to the action of the elastic component 40, the scraper 20 is pressed against the roller mop 32, and the roller mop 32 is a flexible component. The scraper 20 is pressed against the roller mop 32, causing the roller mop 32 to deform to a certain extent. When the pressure applied by the elastic component 40 to the roller mop 32 is too large, the roller body 31 and the roller mop 32 may be stuck and unable to move. In order to solve the above problem, a limiting component 50 is provided in this embodiment. The limiting component 50 is provided between the mounting bracket 10 and the scraper 20, and is used to limit the maximum displacement of the scraper 20 moving toward the roller mop 32. That is to say, when the scraper 20 applies a large pressure to the roller mop 32, the limiting component 50 can apply a force opposite to the elastic force applied by the elastic component 40 to the scraper 20 to the scraper 20, thereby reducing the pressure applied by the scraper 20 to the roller mop 32, and preventing the roller body 31 and the roller mop 32 from being stuck by the scraper 20.

[0044] At the same time, when the cleaning device is used for a long time, it is easy to cause excessive wear of the scraper 20, and in serious cases, parts of the scraper 20 that are not used for wear may also be worn and damaged. The limiting component 50 of this embodiment also has the function of limiting the wear amount of the scraper 20, that is, when the supporting force applied by the limiting component 50 to the scraper 20 is exactly equal to the elastic force applied by the elastic component 40 to the scraper 20, the wear amount of the scraper 20 reaches the maximum, and at this time, the scraper 20 will not continue to press against the roller mop 32 under the action of the limiting component 50.

[0045] Furthermore, an avoidance hole 11 is provided on the mounting bracket 10, and the limiting component 50 includes a limiting member 51, which passes through the avoidance hole 11 and is connected to the scraper 20. The limiting member 51 can move relative to the axial direction of the avoidance hole 11 and stop on the mounting bracket 10 to limit the maximum displacement of the scraper 20 toward the roller mop 32.

[0046] Specifically, when the scraper 20 exerts a relatively large pressure on the roller mop 32, the limiter 51 is driven by the scraper 20 to abut against the mounting bracket 10, and the limiter 51 is subjected to the supporting force exerted by the mounting bracket 10. Through the force transmission effect, the limiter 51 exerts a supporting force on the scraper 20, thereby reducing the pressure exerted by the scraper 20 on the roller mop 32. At the same time, when the wear amount of the scraper 20 reaches the maximum value, the limiter 51 stops on the mounting bracket 10, and the supporting force exerted by the limiter 51 on the scraper 20 is used to balance the elastic force exerted by the elastic component 40 on the scraper 20, and finally stops the scraper 20 from moving toward the roller mop 32.

[0047] Furthermore, the limiting member 51 has a connecting section 511 and a flange section 512. The connecting section 511 passes through the avoidance hole 11 and is connected to the scraper 20. The flange section 512 is connected to an end of the connecting section 511 away from the scraper 20 and protrudes from the outer peripheral surface of the connecting section 511. Figure 1 In the middle Z direction), part of the projection surface of the avoidance hole 11 is located in the projection surface of the flange section 512.

[0048] In this embodiment, part of the projection surface of the avoidance hole 11 is located in the projection surface of the flange section 512, which means that the flange section 512 cannot pass through the avoidance hole 11. When the flange section 512 contacts the outer surface of the avoidance hole 11, it limits the scraper 20. In other words, when the pressure applied by the scraper 20 to the roller mop 32 is too large, the flange section 512 presses against the outer surface of the avoidance hole 11 away from the scraper 20, so that the mounting bracket 10 applies a supporting force to the flange section 512, which makes it difficult for the scraper 20 to move toward the roller mop 32, thereby preventing the roller component 30 from being stuck.

[0049] As attached Figure 8 As shown, the distance L1 between the avoidance hole 11 and the flange section 512 satisfies the relationship: 0≤L1≤5mm.

[0050] Specifically, a certain distance L1 is set between the avoidance hole 11 and the flange section 512 so that the cleaning device can adjust the pressure applied by the scraper 20 to the roller mop 32. That is to say, if the pressure applied by the scraper 20 to the roller mop 32 is relatively large, the flange section 512 abuts against the outer surface of the avoidance hole 11, and L1 is 0 at this time. The limiter 51 applies a supporting force to the scraper 20 to reduce the elastic force applied by the scraper 20 to the roller mop 32, so as to prevent the roller body 31 and the roller mop 32 from stopping rotating. The distance L1 can be used to adjust the supporting force applied by the limiter 51 to the scraper 20. When the maximum value of L1 is relatively large, such as L1 is greater than 5 mm, when the flange section 512 abuts against the outer surface of the avoidance hole 11, the supporting force applied by the limiter 51 to the scraper 20 is relatively small. The value of L1 can be 0, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm and 5mm.

[0051] Further, the avoidance holes 11 include at least two, and the at least two avoidance holes 11 are arranged at intervals along the axial direction of the drum body 31. The limiting members 51 include at least two, and the at least two limiting members 51 and the at least two avoidance holes 11 are arranged in a one-to-one correspondence.

[0052] As attached Figures 1 to 4As shown, in a specific embodiment, the avoidance holes 11 include two, and the two avoidance holes 11 are arranged on the mounting bracket 10 at intervals along the axial direction of the drum body 31, and the limit members 51 include two, and the two limit members 51 pass through the two avoidance holes 11 and are connected to the scraper 20 respectively. Considering that the influence of gravity or other external forces may cause the support force applied by the limit members 51 at various locations of the scraper 20 along the axial direction to be different. Therefore, in this embodiment, by providing two avoidance holes 11 and two limit members 51, the force of the limit members 51 applied to the scraper 20 at various locations along the axial direction is as uniform as possible. Of course, in some embodiments, the avoidance holes 11 and the limit members 51 may also include multiple, so as to further make the support force of the limit members 51 applied to various locations on the scraper 20 more uniform.

[0053] Furthermore, a support column 52 is provided on one side of the scraper 20 close to the mounting bracket 10 , a connecting hole 521 is opened on the support column 52 , the limiter 51 is fixed on the support column 52 through the connecting hole 521 , and the support column 52 is swingably arranged in the avoidance hole 11 .

[0054] Specifically, the support column 52 can improve the connection strength between the stopper 51 and the scraper 20, and prevent the stopper 51 from being separated from the scraper 20 due to the low connection strength between the stopper 51 and the scraper when the scraper 20 moves due to the elastic force of the elastic component 40, so that the pressure exerted by the scraper 20 on the roller mop 32 is too large, and the roller component 30 stops rotating. In addition, in this embodiment, the support column 52 includes at least two, and the two support columns 52 are arranged at intervals along the axis direction of the roller body 31, and are arranged one-to-one with at least two stoppers 51.

[0055] In order to avoid interference between the support column 52 and the avoidance hole 11 when the scraper 20 is moving, in the present embodiment, an avoidance notch 111 is provided on the side wall of the avoidance hole 11. The avoidance notch 111 is located on one side of the swinging direction of the support column 52, and the width L2 of the avoidance notch 111 and the diameter L3 of the support column 52 satisfy the relationship: 0.1mm≤L2-L3≤0.2mm.

[0056] Specifically, when the width L2 of the avoidance notch 111 and the diameter L3 of the support column 52 satisfy the relationship 0.1mm≤L2-L3≤0.2mm, the avoidance notch 111 is neither too large nor too small relative to the support column 52. On the one hand, it can prevent the support column 52 from interfering with the avoidance hole 11 when the scraper 20 moves and drives the support column 52 to move; on the other hand, when the support column 52 moves, it will not completely separate from the avoidance hole 11, resulting in the flange section 512 being unable to abut against the mounting bracket 10. When L2-L3 is less than 0.1mm, the distance between the inner wall surface of the avoidance hole 11 and the support column 52 is small, which easily causes the support column 52 to interfere with the avoidance hole 11. When L2-L3 is greater than 0.2 mm, the distance between the support column 52 and the inner wall of the avoidance hole 11 is too large, which may cause the support column 52 to be driven by the scraper 20, and the flange section 512 to pass through the avoidance notch 111, resulting in the flange section 512 being unable to contact the mounting bracket 10 to limit the scraper 20, and eventually the roller component 30 may stop rotating under the pressure of the scraper 20. The value of L2-L3 can be 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm and 0.2 mm.

[0057] As attached Fig. 9 As shown, the scraper 20 includes a mounting portion 21 and a wiper portion 22, wherein the mounting portion 21 is movably connected to the mounting bracket 10, and the wiper portion 22 is pressed against the roller mop 32. A clamping protrusion 211 is provided on one of the mounting portion 21 and the wiper portion 22, and a clamping groove 221 is provided on the other of the mounting portion 21 and the wiper portion 22, wherein the clamping protrusion 211 is inserted into the clamping groove 221 to connect the mounting portion 21 with the wiper portion 22.

[0058] Specifically, in this embodiment, the part of the scraper 20 that is used for wear is the wiper part 22, and the part used for connecting the mounting bracket 10 is the mounting part 21. The mounting part 21 and the wiper part 22 are detachably connected by a structure of a clamping protrusion 211 and a clamping groove 221. When the wiper part 22 needs to be replaced, it is only necessary to disassemble the wiper part 22 separately and connect the new wiper part 22 to the mounting part 21. The structure of this embodiment is convenient and the cost is low. In addition, the support column 52 is arranged on the wiper part 22, and is connected to the connecting section 511 after passing through the mounting part 21.

[0059] In a specific embodiment, the mounting portion 21 is provided with a plurality of slots 221 spaced apart along the axial direction of the drum body 31, and the wiper portion 22 is provided with a plurality of protrusions 211 spaced apart along the axial direction of the drum body 31. The plurality of protrusions 211 are inserted into the plurality of slots 221 one by one to improve the connection stability between the wiper portion 22 and the mounting portion 21.

[0060] Furthermore, the mounting bracket 10 is provided with a first rotating shaft 12 along the axial direction of the drum body 31, and the mounting portion 21 is rotatably sleeved on the first rotating shaft 12. The elastic component 40 includes a torsion spring 41, which is sleeved on the first rotating shaft 12, and the first end of the torsion spring 41 abuts against the mounting bracket 10, and the second end of the torsion spring 41 abuts against the scraper 20, so that the second end of the scraper 20 has a tendency to move toward the drum mop 32.

[0061] Specifically, during installation, the torsion spring 41 is in a compressed state, and the first end of the torsion spring 41 abuts against the mounting bracket 10. Since the mounting bracket 10 is fixed, the second end of the torsion spring 41 abuts against the scraper 20 and applies elastic force to the scraper 20, so that the mounting portion 21 rotates on the first rotating shaft 12. After the mounting portion 21 rotates, the second end of the scraper 20 has a tendency to move toward the roller mop 32. When the wiper portion 22 is worn, the wiper portion 22 continues to abut against the roller mop 32 under the action of the second end of the torsion spring 41.

[0062] In a specific embodiment, the torsion spring 41 includes a plurality of torsion springs 41, which are sleeved on the first rotating shaft 12 at intervals along the extension direction of the first rotating shaft 12, and the first ends of the plurality of torsion springs 41 abut against the mounting bracket 10, and the second ends of the plurality of torsion springs 41 abut against the wiper portion 22. Optionally, the second ends of the plurality of torsion springs 41 abut against the mounting portion 21.

[0063] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0064] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0065] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
