Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment accessories, and in particular to a mop assembly of a surface cleaning device. Background Art

[0002] With the continuous development of cleaning equipment, cleaning equipment is widely used in people's lives, such as sweeping robots and handheld cleaning devices. These cleaning devices are usually equipped with a mop mechanism. By rotating the mop mechanism relative to the surface to be cleaned, a better cleaning effect can be achieved. However, during the cleaning process, the dirty water on the mop of the mop mechanism usually needs to be removed. A few cleaning devices use a scraper to contact the mop of the mop mechanism. When the mop rotates relative to the scraper, the scraper can scrape off the dirty water and dirt on the mop. Existing mops are usually formed by splicing, and a long gap will be formed at the splicing. The gap is easy to tear during the use of the mop, and the edge of the mop is also easy to burr. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a mop assembly for a surface cleaning device, which increases the strength of the mop edge, prevents the mop edge from burring, and increases the connection strength of the mop splicing position.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A mop assembly of a surface cleaning device, the surface cleaning device comprising a shell, a roller brush chamber being provided on the shell, the mop assembly comprising a roller shaft rotatably arranged in the roller brush chamber and a mop sleeved on the outer surface of the roller shaft, a scraper for scraping and cleaning the mop being provided on the side wall of the roller brush chamber, a scraping edge of the scraper being in contact with the outer surface of the mop, the outer surface of the mop having a first gap formed by splicing, at least one end of the mop being provided with an edge ring, the edge ring having a second gap formed by splicing or overlapping, the first gap and the second gap being staggered in the circumferential direction of the mop.

[0006] In the above technical solution, the edging ring can be used to edge the mop, increase the strength of the mop edge, and prevent the mop edge from burring. The first slit and the second slit are staggered in the circumferential direction, so that the edging ring can completely wrap the first slit of the mop, and the scraper is not likely to tear the first slit of the mop when scraping and cleaning the mop, thereby increasing the connection strength of the mop splicing position.

[0007] Preferably, the mop is provided with the edging ring at both ends. The structure can simultaneously increase the connection strength of the two ends of the mop.

[0008] Preferably, the hydrophobicity of the edging ring is greater than that of the mop.

[0009] Preferably, the two ends of the long strip of edging strip overlap to form the edging ring. When the edging strip overlaps, the inner end extends along the edging strip toward the outer end as the overlapping direction. When the mop cleans the cleaning surface, the rotation direction of the roller is opposite to the overlapping direction of the edging ring. When the scraper is scraping and cleaning, the structure can make the scraper always scrape and clean from the outer end of the edging ring to the inner end of the edging ring along the overlapping direction, making it difficult to pick up the second gap, thereby increasing the reliability of the edging ring connection.

[0010] Preferably, the length of the mop in the axial direction of the roller is smaller than the axial length of the roller. The structure enables the mop to be fully stretched out by the roller in the axial direction, thereby ensuring the cleaning effect of the mop.

[0011] Preferably, at least part of the first slit is spirally wrapped around the outer circumference of the mop. The mop is spliced ​​in a spiral shape to generate a first slit spirally wrapped around the outer circumference of the mop, so that the scraper always has a certain angle relative to the first slit, and the scraper only contacts one point of the first slit at the same time, reducing the tearing effect of the scraper on the first slit.

[0012] Preferably, the first gap is arranged on the outer circumference of the mop in parallel with the rotation axis of the roller.

[0013] Preferably, the mop includes a cleaning layer on the outer surface and a reinforcement layer on the inner surface, and the edging ring covers both the cleaning layer and the reinforcement layer; or, the mop includes a cleaning layer on the outer surface and a reinforcement layer on the inner side, and the edging ring covers the cleaning layer, and at least part of the edging ring is arranged between the cleaning layer and the reinforcement layer. The cleaning layer can play a cleaning effect, and the reinforcement layer can increase the overall strength of the mop.

[0014] Preferably, the strengthening layer is made of rubber or silicone material. The strengthening layer of rubber or silicone material not only has the function of strengthening the overall strength of the mop, but also has a certain anti-slip effect, which can reduce the slip probability of the mop and the roller.

[0015] Preferably, the reinforcement layer is formed on the inner surface of the mop by coating or bonding, or the edge ring is sewn on the mop.

[0016] Preferably, the mop and the roller are detachably arranged, and the structure facilitates the mop to be replaced separately.

[0017] The beneficial effects of the present invention are as follows: 1. The first slit and the second slit are staggered in the circumferential direction, so that the edging ring can completely wrap the first slit of the mop, and the scraper is not easy to tear the first slit of the mop when scraping and cleaning the mop, thereby increasing the connection strength of the mop splicing position. 2. The edging ring forms a partition effect on sewage, which can improve the cleaning effect of the mop. 3. When the scraper is scraping and cleaning, the scraper can always scrape and clean from the end of the edging ring set on the outside to the end of the edging ring set on the inside along the overlapping direction, and it is not easy to pick up the second slit, thereby increasing the reliability of the connection of the edging ring. 4. The first slit spirally surrounding the outer circumference of the mop can make the scraper always larger than the first slit by a certain angle, and the scraper only contacts one point of the first slit at the same time, thereby reducing the tearing effect of the scraper on the first slit. 5. The strengthening layer of rubber material or silicone material not only has the function of strengthening the overall strength of the mop, but also has a certain anti-slip effect, which can reduce the probability of slipping between the mop and the roller. 6. The mop can be replaced individually. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Fig. 9 As shown, another surface cleaning device is introduced in an embodiment of the present invention, which includes a body 4, a floor brush assembly 5 pivotally connected to the bottom of the body, the floor brush assembly includes a shell 5.1, and a drive motor and a mop assembly 1 arranged on the shell 5.1, as shown in FIG. Fig.10 and Fig.11 As shown, the mop assembly 1 includes a roller 6 and a mop 2, the roller includes a first roller 6.1 and a second roller 6.2, the mop is covered on the outer surfaces of the first roller 6.1 and the second roller 6.2, and at least one of the first roller 6.1 and the second roller 6.2 is connected to the driving motor to drive the mop to contact the surface to be cleaned.

[0033] In one embodiment, Fig.10 and Fig.11 As shown, the first roller 6.1 and the second roller 6.2 are arranged front and back, wherein the diameter of the first roller 6.1 is smaller than the diameter of the second roller 6.2, and the drive motor is drivingly connected to the second roller 6.2.

[0034] It can be understood that, in another embodiment, the diameter of the first roller 6.1 is equal to the diameter of the second roller 6.2, and the drive motor is drivingly connected to the second roller 6.2.

[0035] Embodiment 1:

[0036] A mop assembly for a surface cleaning device, the surface cleaning device comprising a housing, the housing being provided with a roller brush chamber, such as Figure 1 and Figure 2 As shown, the mop assembly includes a roller shaft rotatably arranged in the roller brush chamber and a mop 2 sleeved on the outer surface of the roller shaft, the mop is provided with bristles for wiping the surface to be cleaned, and a scraper 7 for scraping and cleaning the mop 2 is provided on the side wall of the roller brush chamber, and the scraping edge of the scraper 7 is in contact with the outer surface of the mop 2, the outer surface of the mop 2 has a first gap 2.1 formed by splicing, at least one end of the mop 2 is provided with an edge ring 3, and the edge ring 3 has a second gap 3.1 formed by splicing or overlapping, and the first gap 2.1 and the second gap 3.1 are staggered in the circumferential direction of the mop 2.

[0037] The strip-shaped mop 2 usually has the advantages of being easy to process and low in cost. Therefore, when making the ring-shaped mop 2, the two ends of the strip-shaped mop 2 are spliced ​​together to form a ring-shaped structure. However, due to the limitation of the manufacturing process, a gap will be formed at the splicing of the two ends of the mop 2, namely the first gap 2.1 mentioned above. In the above technical scheme, the edging ring 3 can hem the mop 2, increase the strength of the edge of the mop 2, and make the edge of the mop 2 less likely to burr. The first gap 2.1 and the second gap 3.1 are staggered in the circumferential direction, so that the edging ring 3 can completely wrap the first gap 2.1 of the mop 2. When the scraper scrapes and cleans the mop 2, it is not easy to tear the first gap 2.1 of the mop 2, thereby increasing the connection strength of the splicing position of the mop 2.

[0038] Furthermore, the axial width of the mop covered by the edge ring is not greater than the length of the bristles. The width of the mop covered by the edge ring is not greater than the length of the bristles, so that the bristles close to the edge ring and not covered by the edge ring can fall to one side of the edge ring during the cleaning process, which can not only increase the cleaning area in the axial direction, but also hide the side of the edge ring under the bristles, reducing the tearing of the side of the edge ring during the roller brush cleaning process and affecting the connection strength of the edge ring.

[0039] When the scraping edge of the scraper contacts the outer surface of the mop 2, there is a certain amount of interference between the two, but the scraper will not hinder the normal rotation of the mop 2. When the mop 2 rotates relative to the scraper, the scraper can scrape and clean along the surface of the mop 2 to scrape off the sewage, dirt, etc. on the mop 2. The mop 2 and the roller are detachably arranged, and the scraper is arranged along a preset direction, and the axial direction of the rotating shaft of the roller is roughly parallel to the preset direction. The length of the mop 2 in the axial direction of the roller is less than the axial length of the roller. When the mop 2 is sleeved on the outer surface of the roller, it has an interference fit with the roller, that is, the roller tightens the mop 2.

[0040] like Figure 1 and Figure 2As shown, on the basis of Example 1, the two ends of the mop 2 are provided with the edging ring 3, and the hydrophobicity of the edging ring 3 is greater than that of the mop 2, so that the edging ring 3 can form a partition effect on the sewage, and the edging rings 3 at both ends can simultaneously increase the connection strength of the two ends of the mop 2. When the mop 2 is mopping the floor, the sewage on one side of the mop 2 is not easy to pass through the edging ring 3 and leak to the side where the mop 2 is not set, which can improve the cleaning effect of the mop 2.

[0041] like Figure 3 As shown, on the basis of Example 1, the annular edging ring 3 is formed by overlapping the two ends of the long edging strips, and the connection strength of the edging ring 3 formed by the overlap is greater. When the edging strips overlap, the end set on the inner side extends along the edging strips to the end set on the outer side as the overlapping direction. When the mop 2 cleans the cleaning surface, the rotation direction of the roller is opposite to the overlapping direction of the edging ring 3. When the mop 2 cleans the cleaning surface, the structure can make the scraper always scrape and clean from the end of the edging ring 3 set on the outer side to the end of the edging ring 3 set on the inner side along the overlapping direction, and it is not easy to pick up the second gap 3.1, thereby increasing the reliability of the connection of the edging ring 3. Figure 3 The ω direction is the overlapping direction, and the ψ direction is the rotation direction of the roller when the mop 2 cleans the cleaning surface.

[0042] In another embodiment, Figure 4 As shown, the annular edging ring 3 is formed by closely splicing the two end surfaces of the long edging strip. The structure can make the second gap 3.1 free of protrusions.

[0043] like Figure 7 and Figure 8 As shown, on the basis of Example 1, at least part of the first slit 2.1 is spirally arranged around the outer periphery of the mop 2. By setting at least part of the slit of the mop 2 in a spiral shape, when the scraper is scraping and cleaning the mop 2, the entire scraper will not contact the edge of the first slit 2.1 of the mop 2 at the same time, thereby reducing the area where the entire scraper is in contact with the first slit 2.1 at the same time, and a smaller part of the entire scraper is in contact with the first slit 2.1 at the same time, greatly reducing the amount of interference between the scraper and the edge of the mop 2 located at the first slit 2.1, so that when the mop 2 rotates relative to the scraper, the mop 2 will rotate more smoothly, and because the scraper intersects with the first slit 2.1, the scraper can pass through the slit smoothly, and the scraper will not be stuck in the slit, thereby avoiding the scraper being stuck in the first slit 2.1.

[0044] like Figure 5As shown, on the basis of Example 1, the mop 2 includes a cleaning layer 2.2 on the outer surface and a strengthening layer 2.3 on the inner surface, the strengthening layer 2.3 is formed on the inner surface of the mop 2 by coating or bonding, the strengthening layer 2.3 is made of rubber material or silicone material, and the edging ring 3 covers the cleaning layer 2.2 and the strengthening layer 2.3 at the same time. The cleaning layer 2.2 can absorb water and remove dirt. When the mop 2 is processed, the cleaning layer 2.2 is first spliced, and then the strengthening layer 2.3 is formed on the inner surface of the mop 2 by coating or bonding, and then the mop 2 is edged, so that the edging ring 3 can cover the cleaning layer 2.2 and the strengthening layer 2.3 at the same time. The cleaning layer 2.2 can play a cleaning effect, and the strengthening layer 2.3 not only has the function of strengthening the overall strength of the mop 2, but also has a certain anti-slip effect, which can reduce the slip probability of the mop 2 and the roller. The strengthening layer 2.3 formed by coating or bonding has integrity and no seams, which can increase the overall connection strength of the mop 2 and prevent it from breaking easily. Specifically, at least one side of the edging ring 3 is provided with a flange 3.2. Figure 5 In the embodiment, flanges 3.2 are provided on both the outer and inner sides of the edging ring 3. The flanges on the inner side can increase the friction between the mop and the roller shaft, and reduce the possibility of the mop sliding axially relative to the roller shaft; and the flanges on the outer side can better protect the bristles.

[0045] In another embodiment, Figure 6 As shown, the mop 2 includes a cleaning layer 2.2 arranged on the outer surface and a reinforcing layer 2.3 on the inner side. The reinforcing layer 2.3 is formed on the inner surface of the mop 2 by coating or bonding. The reinforcing layer 2.3 is made of rubber or silicone material. The edging ring 3 covers the cleaning layer 2.2, and at least part of the edging ring 3 is arranged between the cleaning layer 2.2 and the reinforcing layer 2.3. The cleaning layer 2.2 can absorb water and remove dirt. When the mop 2 is processed, the cleaning layer 2.2 is first spliced, and then the cleaning layer 2.2 on the outer surface is edged so that the edging ring 3 covers the cleaning layer 2.2, and then the reinforcing layer 2.3 is formed on the inner surface of the mop 2 by coating or bonding so that at least part of the edging ring 3 is arranged between the cleaning layer 2.2 and the reinforcing layer 2.3. The cleaning layer 2.2 can achieve a cleaning effect, and the strengthening layer 2.3 not only strengthens the overall strength of the mop 2, but also has a certain anti-slip effect, which can reduce the slip probability of the mop 2 and the roller. The strengthening layer 2.3 formed by coating or bonding has integrity, and the strengthening layer 2.3 has no seams, which can increase the strength of the mop 2. Specifically, the flange 3.2 provided only on the outer side of the edging ring 3 can better protect the bristles.

[0046] It can be understood that the mop in this embodiment can be mounted on the outside of the cylindrical roller, and the mop can also be mounted on the outside of the rotating assembly composed of a driving roller and a rotating roller arranged side by side and at intervals. The mop in the tensioned state is roughly an elliptical cylindrical structure, and the rotating assembly can realize the function of the roller.
